Description

Walking aids

The present invention relates to a medical assistive device, in particular a walking aid.

For patients with hemiplegia caused by stroke, they must rely on assistive devices to stand up from the bedside or walk for rehabilitation. Therefore, a support frame is usually set up next to the patient's bed to assist in standing up from the bedside, and a walker is placed next to the bed. As a result, a variety of assistive devices must be prepared at home. In addition, most of the walkers currently used by hemiplegic patients are designed as canes. However, when using such a cane-type walker, because the distance between the four support points is not large, if the cane-type walker is too close to the body, if the patient's body center of gravity is too far to the side due to the movement of the steps, the patient will find it difficult to rely on the cane-type walker to support the body, and it is easy to fall. When the cane-type walker is supported at a position farther away from the body in order to prevent falls, this support method will make it difficult for the patient to apply force, and it is not very convenient to use.

Therefore, the purpose of the present invention is to provide a walking aid that can improve at least one disadvantage of the prior art.

Therefore, the walker of the present invention includes a first leg mechanism and a second leg mechanism spaced apart from each other, and a gripping rod mechanism and a bridging rod mechanism spaced apart from each other between the first leg mechanism and the second leg mechanism.

The first leg mechanism includes two first leg modules extending up and down and spaced in front and back, a first upper rod extending in front and back and straddling between the top ends of the first leg modules, and a first cross rod straddling between the first leg modules and spaced below the first upper rod. The second leg mechanism includes two second leg modules extending up and down and spaced in front and back, a second upper rod extending in front and back and straddling between the top ends of the second leg modules, and a second cross rod straddling between the second leg modules and spaced below the second upper rod. The spacing between the second footbar modules is smaller than the spacing between the first footbar modules, and the height of the second upper bar is smaller than the height of the first upper bar.

The gripping rod mechanism is connected to the first upper rod, and extends outwards in the left and right directions from the first upper rod, bends downwards and extends to connect to the second upper rod. The cross-linking rod mechanism is connected between the first cross-link rod and the second cross-link rod.

The effect of the present invention is that through the structural design of the first leg mechanism and the second leg mechanism with different widths and different heights, and the structural design of the gripping rod mechanism and the cross-linking rod mechanism straddling the first leg mechanism and the second leg mechanism at intervals, the walker of the present invention has multiple uses and can provide a more stable support in the front, back, left and right directions.

Before the present invention is described in detail, it should be noted that similar components are represented by the same numbers in the following description.

Referring to Figures 1, 2, 3, and 4, a first embodiment of the walker 200 of the present invention is suitable for use by a paraplegic user 900, and can be placed in front of the user 900 as a walking aid (as shown in Figure 2), or placed at the side of the user 900 as a crutch (as shown in Figure 3), or can be used as a standing aid when standing up from the edge of the bed (as shown in Figure 4).

The walker 200 includes a first leg mechanism 3 and a second leg mechanism 4 extending vertically and spaced apart from each other, a gripping rod mechanism 5 extending horizontally and spanning between the top ends of the first leg mechanism 3 and the second leg mechanism 4, and a cross-linking rod mechanism 6 extending horizontally and spanning between the first leg mechanism 3 and the second leg mechanism 4 and spaced apart below the gripping rod mechanism 5. In this embodiment, the first leg mechanism 3 and the second leg mechanism 4 are generally in a state of extending upwardly and obliquely toward each other, but the implementation is not limited to this and may also be in an upright parallel state.

Referring to Figures 1, 5, and 6, the first leg mechanism 3 includes two first leg modules 31 extending up and down and spaced front and back, a first upper rod 32 extending front and back and spanning between the top ends of the first leg modules 31, and a first cross rod 33 extending front and back and spanning between the first leg modules 31 and spaced below the first upper rod 32.

Each first foot bar module 31 includes a first fixed rod 311 extending up and down and connected to the first upper rod 32 at its top end, a first foot bar 312 mutually sleeved with the first fixed rod 311 and used to support the ground, and a first telescopic positioning member 314. The first foot bar 312 can be telescopically adjusted up and down relative to the first fixed rod 311 to change the vertical extension length of the entire first foot bar module 31. The first telescopic positioning member 314 is installed on one of the first fixed rod 311 and the first foot bar 312, and can be detachably connected to the other of the two, so that the first foot bar 312 can be telescopically adjusted and positioned relative to the first fixed rod 311.

The first upper rod 32 is radially penetrated with a plurality of first positioning holes 321 spaced apart in front and back. The first cross rod 33 is connected between the bottom ends of the first fixing rods 311 and is located above the first foot rods 312.

In this embodiment, each of the first foot rods 312 has a plurality of telescopic positioning holes 313 that penetrate radially and are spaced vertically along the length thereof. Each of the first telescopic positioning members 314 is a positioning spring buckle that is fixedly mounted in the corresponding first fixing rod 311 and radially passes out of the outer peripheral surface of the first fixing rod 311. The first telescopic positioning member 314 is inserted into one of the telescopic positioning holes 313 of the corresponding first foot rod 312, so that the first foot rod 312 is telescopically adjusted and positioned relative to the first fixing rod 311. Since there are many types of structures that can extend and adjust the length of the first foot bar module 31, and it is not the focus of the improvement of the present invention, it will not be described in detail, and the implementation is not limited to the above-mentioned implementation.

The second leg mechanism 4 includes two second leg modules 41 extending up and down and spaced front and back, a second upper rod 42 extending front and back and straddling between the top ends of the second leg modules 41, and a second cross rod 43 extending front and back and straddling between the second leg modules 41 and spaced below the second upper rod 42.

Each second foot bar module 41 includes a second fixed rod 411 extending up and down and connected to the second upper rod 42 at its top end, a second foot bar 412 which is mutually sleeved with the second fixed rod 411 and used to support the ground, and a second telescopic positioning member 414. The second foot bar 412 can be telescopically adjusted up and down relative to the second fixed rod 411 to change the vertical extension length of the entire second foot bar module 41. The second telescopic positioning member 414 is installed on one of the second fixed rod 411 and the second foot bar 412, and can be detachably connected to the other of the two, so that the second foot bar 412 can be telescopically adjusted and positioned relative to the second fixed rod 411.

The second upper rod 42 is radially provided with a plurality of second positioning holes 421 spaced apart from each other. The second crossbar 43 is connected between the bottom ends of the second fixing rods 411, located above the second foot rods 412, and the second crossbar 43 is at the same height as the first crossbar 33.

In this embodiment, the vertical extension height of the second footbar modules 41 is less than the vertical extension height of the first footbar modules 31, and the front-to-back distance of the second footbar modules 41 is less than the front-to-back distance of the second footbar modules 41, so that the height of the second upper rod 42 is lower than the height of the first upper rod 32, the length of the second upper rod 42 is less than the length of the first upper rod 32, and the length of the second crossbar 43 is less than the length of the first crossbar 33.

In this embodiment, each of the second foot rods 412 has a plurality of upper and lower intervals and a telescopic positioning hole 413 for the second telescopic positioning member 414 to be inserted into. Since the structural design of the telescopic adjustment of the second foot rod modules 41 is the same as that of the first foot rod modules 31, it will not be described in detail.

Referring to Figures 5, 6, and 7, the gripping rod mechanism 5 includes a first adjustment module 51 mounted on the first upper rod 32, a second adjustment module 52 mounted on the second upper rod 42, a gripping rod 53 bent and extended up and down and mounted between the first adjustment module 51 and the second adjustment module 52, and a first locking member 54 and a second locking member 55 mounted on the first adjustment module 51 and the second adjustment module 52, respectively.

The first adjustment module 51 includes a first adjustment seat 511 that can be adjusted forward and backward and sleeved outside the first upper rod 32, and a first positioning pin 514 that is screwed into the first adjustment seat 511 and inserted into one of the first positioning holes 321 of the first upper rod 32. The first adjustment seat 511 has a hinge portion 513 facing one side of the second leg mechanism 4. By inserting the first positioning pin 514 into one of the first positioning holes 321, the first adjustment seat 511 can be adjusted and positioned relative to the first upper rod 32.

The second adjustment module 52 has a second adjustment seat 521 that can be installed on the second upper rod 42 to be adjustable forward and backward, and a second positioning pin 523 that is threadedly installed on the second adjustment seat 521 and penetrates one of the second positioning holes 421 of the second upper rod 42. By inserting the second positioning pin 523 into one of the second positioning holes 421, the second adjustment seat 521 can be adjusted and positioned relative to the second upper rod 42. The second adjustment seat 521 has a clamping groove 522 that opens upward and penetrates forward and backward.

Since the structural design of the first adjustment module 51 being able to adjust and position relative to the first upper rod 32 and the structural design of the second adjustment module 52 being able to adjust and position relative to the second upper rod 42 are both existing technologies and have many types, they will not be described in detail, and the implementation is not limited to the above-mentioned implementation forms.

The gripping rod 53 is generally L-shaped, and has a gripping section 531 that is pivoted to the hinge portion 513 via a vertical pivot shaft 512 and horizontally protrudes toward the second leg mechanism 4, and a supporting section 532 that bends downward from the protruding end of the gripping section 531 and is engaged with the engaging groove 522 of the second adjustment seat 521. The gripping rod 53 can be operated to pivot horizontally between a gripping position that straddles the first upper rod 32 and the second upper rod 42 via the pivot shaft 512, and a folded position that is away from the second upper rod 42 and is disposed next to the first leg mechanism 3. The pivot changes of the grip bar 53 will be described later.

The first locking member 54 can be loosely screwed downwardly through the hinge portion 513 of the first adjustment seat 511, and can be detachably inserted radially through the gripping section 531, thereby fixing the gripping section 531 in a non-pivotable manner on the first adjustment seat 511. The second locking member 55 can be loosely screwed transversely through the second adjustment seat 521, and can be detachably inserted radially through the supporting section 532, thereby positioning the bottom end of the supporting section 532 in the clamping groove 522.

Referring to Figures 5, 6, and 8, the cross-link mechanism 6 includes two mounting seats 61 rotatably mounted on the first cross-link 33 and the second cross-link 43, respectively, a cross-link rod 62 that can be moved forward and backward and relatively rotated across the mounting seats 61, and two positioning members 63 that are screwed and mounted on the mounting seats 61.

Each mounting seat 61 has a first rotating seat tube 611 rotatably mounted on the corresponding first crossbar 33 or the second crossbar 43, and a second rotating seat tube 613 coaxially connected to the side of the first rotating seat tube 611 and adjacent to another mounting seat 61.

The cross-connection rod 62 is generally in a U-shape with an opening facing backwards, and has two ends 621 extending forward and backward and respectively inserted in the second rotating seat tubes 613 so as to be movable forward and backward and relatively rotated, and a cross-connection portion 623 connected between the ends 621. Each of the ends 621 is radially penetrated with a third positioning hole 622. The cross-connection rod 62 can be pivoted between a horizontally supporting position between the first leg mechanism 3 and the second leg mechanism 4 and a folded position of being upright and leaning against the first leg mechanism 3 via the mounting seats 61. The pivoting change of the cross-connection rod 62 will be described later.

Each positioning member 63 passes through the corresponding first rotating seat tube 611, and is radially threaded through the first rotating seat tube 611 and the second rotating seat tube 613, and passes through the corresponding first crossbar 33 or the second crossbar 43, and passes through the corresponding third positioning hole 622 of the end 621, thereby locking the corresponding mounting seat 61, the corresponding first crossbar 33 or the second crossbar 43, and the crossbar 62 together.

1 and 2 , when the first embodiment of the walker 200 of the present invention is used, if it is to be placed in front of the user 900 as a walking aid, the first leg frame mechanism 3 and the second leg frame mechanism 4 can be adjusted to be spaced apart from each other, so that the first leg frame mechanism 3 with a higher height is located on the side of the user 900 where the user 900 can move normally, and the cross-connecting rod 62 is adjusted to be U-shaped with the opening side facing the user 900, so that the first leg frame mechanism 3 and the second leg frame mechanism 4 are respectively located on the left and right sides of the normal lower limbs of the user 900, that is, the second leg frame mechanism 4 with a lower height is relatively between the two feet. At this time, the user 900 can grasp the gripping rod 53 with a hand that is functioning normally to support the upper body, and can use the walker 200 to assist in walking.

Referring to Figs. 1 and 3, when the walker 200 is to be placed at the side of the user 900 to be used as a crutch, the walker 200 can be rotated and adjusted to a posture in which the first leg frame mechanism 3 is in front and the second leg frame mechanism 4 is in the back. Then, the user 900 can grasp the gripping rod 53 located at the side with a normal hand to support the upper body and use it as a crutch. When the walker 200 is moved forward a certain distance and then the user grasps the gripping rod 53 and steps forward, since the left and right spacing of the second leg frame mechanism 4 is smaller, that is, the left and right width of the second leg frame mechanism 4 is narrower, when the user 900 steps forward with the foot near one side of the walker 200, The second leg mechanism 4 will not be hit, and because the first leg mechanism 3 and the second leg mechanism 4 are roughly distributed on the front and rear sides of the body, and the left and right spans of the first leg rod modules 31 and the second leg rod modules 41 are large, they can provide excellent support stability in the front, rear, left and right directions, and can stably support the user 900.

Referring to Figures 1 and 4, when the walker 200 is used as an assistive device for standing up from the bedside, the second leg mechanism 4 with a lower height can be turned toward the bedside, and the first leg mechanism 3 with a higher height can be relatively far away from the bedside. Then, the user 900 faces the second leg mechanism 4 and grasps the two ends 621 of the first upper rod 32 with both hands, or grasps the first upper rod 32 and the gripping rod 53 with both hands to help push the body forward and upward.

Referring to Figures 1, 5, and 6, when the gripping rod 53 needs to be shifted forward and backward, the first positioning pin 514 and the second positioning pin 523 can be driven to separate from the first upper rod 32 and the second upper rod 42 respectively, and the gripping rod 53 can be pushed and pulled forward and backward to drive the first shifting seat 511 and the second shifting seat 521 to shift forward and backward relative to the first upper rod 32 and the second upper rod 42 respectively. After the shifting, the first positioning pin 514 is inserted into one of the first positioning holes 321 of the first upper rod 32, and the second positioning pin 523 is inserted into one of the second positioning holes 421 of the second upper rod 42, and the shifting is completed.

Referring to Figs. 1, 9 and 10, when the walker 200 is to be folded, the gripping rod 53 and the cross-connecting rod 62 are operated to be changed to the folded position in sequence. When the gripping rod 53 is to be driven to be changed to the folded position, the first locking member 54 and the second locking member 55 are operated to be respectively disengaged from the gripping section 531 and the supporting section 532 of the gripping rod 53. Then, the gripping rod 53 is pushed forward or backward to drive the supporting section 532 of the gripping rod 53 to be disengaged from the clamping groove 522 of the second adjustment seat 521, and to be horizontally pivoted relative to the first adjustment seat 511, and to be placed against one of the first foot bar modules 31 to be limited. Next, the first locking member 54 is reset relative to the first adjustment seat 511, so that the first locking member 54 passing through the hinge portion 513 of the first adjustment seat 511 is limitedly blocked against the side of the gripping rod 53 facing away from the first tripod mechanism 3. At this time, the gripping rod 53 is positioned in the folded position.

When the cross-connection rod 62 is driven to change to the folded position, the positioning members 63 are detached from the mounting seats 61 respectively. Then, the cross-connection rod 62 is driven upward relative to the first leg mechanism 3, so that the cross-connection rod 62 links the corresponding mounting seat 61 to swing upward relative to the first cross bar 33 toward the first leg mechanism 3, and at the same time, the second leg mechanism 4 is driven to swing upward toward the first leg mechanism 3 through the corresponding mounting seat 61. At this time, the cross-connection rod 62 has changed to the folded position. After the walker 200 completes the folding operation, the volume can be greatly reduced, which is convenient for storage.

In this embodiment, each end 621 of the cross-connection rod 62 is provided with only one third positioning hole 622. However, in another embodiment of the present invention, a plurality of third positioning holes 622 spaced in front and back may be provided at each end 621, so that the cross-connection rod 62 has the function of being able to be moved forward and backward.

Referring to Figures 11 and 12, the difference between a second embodiment of the walker 200 of the present invention and the first embodiment lies in the structural design of the gripping rod mechanism 5 and the cross-connecting rod mechanism 6. For the convenience of explanation, the following will only describe the differences between the embodiments.

In the second embodiment, the gripping rod mechanism 5 and the cross-linking rod mechanism 6 are non-pivotably installed between the first tripod mechanism 3 and the second tripod mechanism 4.

The gripping rod mechanism 5 includes a first adjustment module 51 mounted on the first upper rod 32 so as to be adjustable forward and backward, a second adjustment module 52 mounted on the second upper rod 42 so as to be adjustable forward and backward, and an L-shaped gripping rod 53 fixedly connected between the first adjustment module 51 and the second adjustment module 52.

The cross-link rod mechanism 6 includes two cylindrical mounting seats 61 respectively mounted and fixed on the sides of the first cross-link rod 33 and the second cross-link rod 43, a U-shaped cross-link rod 62 with its two ends 621 respectively inserted in the mounting seats 61 so as to be adjustable forward and backward, and two detachable positioning members 63 respectively radially penetrated in the mounting seats 61 and respectively penetrated in the ends 621. Each of the mounting seats 61 is radially penetrated with a plurality of adjustment and alignment holes 614 spaced forward and backward. Each of the ends 621 of the cross-link rod 62 is radially penetrated with a third positioning hole 622.

Each positioning member 63 has a clip portion 631 that is roughly C-shaped and has a radial opening, and a latch portion 632 that radially protrudes outward from the curved inner surface of the clip portion 631 and passes through the opening of the clip portion 631. When the positioning member 63 is installed, the latch portion 632 passes through one of the corresponding displacement alignment holes 614 of the mounting seat 61 and is inserted into the third positioning hole 622 of the corresponding end portion 621. Then, the clip portion 631 is elastically deformed and clipped to be positioned outside the mounting seat 61, and the installation is completed.

Since the method of shifting the gripping rod 53 and the cross-connecting rod 62 forward and backward relative to the first leg mechanism 3 and the second leg mechanism 4 is substantially the same as that of the first embodiment, it will not be described in detail.

In summary, through the structural design of the first leg mechanism 3 and the second leg mechanism 4 with different widths and heights, and the structural design of the gripping rod mechanism 5 and the bridging rod mechanism 6 straddling the first leg mechanism 3 and the second leg mechanism 4 at intervals, the walker 200 of the present invention has multiple uses and can be placed in front of the user 900 to do It can be used as a walking aid, and can also be placed at the side of the user 900 to be used as a crutch, and can be placed beside the bed to be used as a supporting aid when getting up from the edge of the bed. Because the first leg rod modules 31 of the first leg frame mechanism 3 and the second leg rod modules 41 of the second leg frame mechanism 4 have a larger span, a more stable supporting effect can be provided in the front, rear, left and right directions.

In addition, the gripping rod 53 can be folded and placed against the first leg mechanism 3, the cross-linking rod 62 can link the second leg mechanism 4 to be folded and placed against the first leg mechanism 3, and the first leg module 31 and the second leg module 41 can be adjusted up and down. The volume of the walker 200 can be greatly reduced, and it is convenient to carry and store. Therefore, the walker 200 of the present invention is indeed a very innovative and convenient creation, which can indeed achieve the purpose of the present invention.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
