Description

Hinge-crutch with asymmetrical footrest < RTI ID = 0.0 >

The present invention relates to a hinged crutch using an asymmetric foot plate. More particularly, the present invention relates to a hinged crutch for an asymmetric foot, which is rotated at a predetermined angle with respect to a hinge, The present invention relates to a hinged crutch using an asymmetric footrest which is easy to stand.

Generally, crutches are widely used as an assistive device to help people who have difficulty in legs walking. 1, the crutches 100 generally include a pair of upper rods 110 arranged in a direction perpendicular to the paper surface at regular intervals, a pair of upper rods 110 disposed on the upper ends of the pair of upper rods 110, A cradle 120 coupled across both upper rods 110 to support a user's armpit and a pair of upper rods 110 on the underside of the cradle 120, And a lower rod 140 coupled between the lower ends of the pair of upper rods 110 to be positioned between the upper rods 110. The lower rod 140 is attached to a lower end of the lower rod 140 And a crutch tip (150) whose tip contacts the ground.

At this time, the handle 130 and the lower rod 140 can adjust the height of the upper rod 110 so that the upper rod 110 can be adjusted to the user's body condition. By forming holes in the height direction at regular intervals and fixing them with bolts or the like). Examples of such crutches include Korean Registered Utility Model Registration No. 20-0375949, "Adjustable Length Crutches", No. 20-0398697 "Crutches", and No. 20-0408358 "Crutch height adjusters" .

On the other hand, crutches that combine various technologies for people who are physically difficult to move due to the nature of crutches are being proposed. For example, Korean Patent Registration No. 10-0520273 entitled "crutches" generates a tightening force through a screw fastening structure and uses the tightening force to adjust the length of the upper length adjusting rod (upper rod) and the lower length adjusting rod So that the convenience of use can be ensured and the crutches are expected to have an effect of preventing the reliability of the product from being lowered due to the decrease in the elastic force of the spring in the past. A registration crutch can be used as the crutch for the crutches. The crutches (the upper and lower rods) are formed of a plurality of length-adjustable rods (variable rods) The present invention proposes crutches that are expected to have an effect that a cane combined with crutches can be more easily used in accordance with the body / body condition of the user by simply loosening or loosening the variable cone. In addition, the registration number 20-0356738 "crutches with elasticity" can buffer the impact transmitted through the lower neck (lower rod) by a buffer so as to reduce impact transmitted to the user's side and wrist. It also suggests crutches that are expected to be used without any inconvenience. Regarding the "piston crutches ", registration number 20-0416352, a piston is provided under the upper structure of a crutch, so that it is possible to walk smoothly not only on a flat surface but also on a stepped portion such as a stair, And the effect of walking for a long time is expected.

Although the crutches developed by applying various techniques to the disabled persons having difficulty in legs are provided, the crutches according to the prior art are not applied ergonomically, which is somewhat inconvenient for the user to move the crutches.

Particularly, the crutches according to the prior art have a relatively sharp protrusion at the bottom, which is very inconvenient for walking on a soft ground.

That is, the conventional crutches and the crutches proposed by the prior art, when the user moves using the crutches, first move the crutches forward, and then the crutch tip 150 is tilted to the ground and then the crutches tip 150 of the crutches is subjected to a load (Generated because the user is leaning on the crutch), the crutch tip 150, which is configured to walk while repeating the operation of moving the body, is very dangerous when it is walked on a soft flat surface There is also. Therefore, in the case of the conventional crutches, the walking stability of the user who is walking on the crutches while being dependent on the weight is inevitably degraded.

Also, since the crutch formed by the crutch tip 150 having a small contact area according to the pendulum movement of the crutches, the entire body moves while applying a large load, so that the bottom surface tends to fall when the attention is dispersed slightly during the slipping or walking. There is a problem that the risk of secondary accident is high.

Therefore, various crutches such as crutches with four feet have been introduced as an alternative, and these crutches are mainly used by children or elderly people who have insufficient strength.

As described above, crutches have been used for a wide range of function-oriented purposes that assist the walking of patients who are uncomfortable, irrespective of age and gender. However, since the crutches of FIG. 1 can not stand on its own, , Which is unsuitable for hygiene.

In addition, even if these crutches are kept upright, there is an inefficient use of the space because a separate space to be leaned or a separate element (for example, a tripod mechanism) is required. And crutches with four feet may be able to stand on their own, but space efficiency is not so good because of the space they occupy. Especially, in hospitals and nursing homes that have a large amount of crutches, it is difficult to overlook their space efficiency.

Therefore, there is an urgent need for improvements according to the problems and necessities as described above.

Korea Registration No. 20-0356738 "crutches with elasticity" (registered on July 7, 2004). Korean Registration No. 20-0416352 "Piston crutches" (registered on May 5, 2006.)

Fig. 7 is a view showing a hinge crutch using an asymmetric footrest according to another embodiment.

Referring to the drawings, a hinged crutch using an asymmetric footrest according to an embodiment of the present invention includes a body 10, a footrest 20 installed at a lower end of the body 10, a rotation guide A crutches 40 for protecting the footrest 20 and a locking part 50 for fixing the rotation of the footrest.

Accordingly, as shown in FIG. 2, the hinged crutch using the asymmetric footrest according to the embodiment of the present invention includes a main body 10 supporting a user's body and having a hinge portion 11 at a lower portion thereof; A foot plate 20 installed at the lower end of the main body 10 and connected to the hinge 11 so as to be able to rotate at a predetermined angle and having an asymmetric center; And a rotation guide (30) protruding on both sides of the hinge portion (11) to limit the forward and backward rotation of the footrest (20).

In addition, the rotation guide 30 may be provided with an elastic member 31 having a predetermined thickness at a position corresponding to the foot plate 20.

And may further comprise a boot-shaped crutches 40 detachably coupled to the footstool 20 and covering the bottom of the footstep 20 and capable of absorbing the impact of contact with the support surface.

A hollow space 51 extending through the inside of the hinge portion 11 and the foot plate 20 is formed so that the foot plate 20 can be rotated or fixed to the body 10 as shown in Fig. The locking bar 50 may further include a locking part 50 which is slidable along the space and can be locked or unlocked.

Also, as shown in FIG. 4, in the hinged crutches using the asymmetric footplate according to the embodiment of the present invention, the foot plate 20 may be an arcuate shape that is convex upward as in the shape of a sole.

FIG. 5 is a view showing an exemplary state in which a user uses a hinged crutch using an asymmetric footrest according to an embodiment of the present invention according to the present invention, and FIG. 6 is a view showing an example of a state in which the user uses an asymmetric footrest according to another embodiment of the present invention, Fig. 6 is a view showing an exemplary state using a hinge crutch used; Fig.

The components of the hinged crutch using the asymmetric footrest according to the embodiment of the present invention will now be described.

The main body 10 supports the user's body and a hinge portion 11 is formed at a lower portion thereof. That is, referring to FIG. 1, a pair of upper rods 110, which are arranged in parallel to each other at regular intervals and in a direction perpendicular to the paper surface, and a pair of upper rods 110, A handle 130 that is coupled across a pair of upper rods 110 on the underside of the cradle 120 to allow the user to hold the cradle 120 by hand, And a lower rod 140 coupled to be positioned between both upper rods 110 at the lower end of the upper rod 110 of the lower rod 140. The hinge portion 11 is formed at the lower portion of the lower rod 140.

In particular, the hinge portion 11 prevents the foot plate 20, which will be described later, from being detached from the body 10 and guides the foot plate 20 to rotate at a predetermined angle.

The footrest 20 is installed at the lower end of the main body 10 and is connected to the hinge portion 11 to be able to rotate at a predetermined angle, and is formed in an asymmetric structure with its center being offset to one side.

As shown in FIG. 2, the foot plate 20 is formed with a predetermined thickness and contacts the support surface 90 on the flat surface to disperse and support the weight of the user.

The foot plate 20 can support the crutches on the support surface 90 more stably than when the user is walking because the contact surface of the foot plate 20 with the support surface 90 is wider than the conventional crutch tip.

In particular, the footrest 20 of the present invention is an asymmetric structure in which the center connected to the hinge portion 11 is biased rearwardly from the front-rear center of the footrest 20. Therefore, in the same material with the center of the footrest 20 as a reference, the front is heavier than the rear and descends downward. At this time, it rotates naturally around the hinge portion 11. This natural rotation causes the foot plate 20 and the support surface 90 to be horizontal in correspondence with the inclined angle of the body 10 when the user is walking. The leveled footrest 20 evenly contacts the support surface 90 so that the load is dispersed so that the user does not need to waste force to artificially keep the footrest 20 horizontal with the support surface 90.

Therefore, the conventional hinge unit 11, the foot plate 20, the rotation guide 30, and the like, which can perform an ergonomic joint function, can not be implemented, The present invention can achieve the desired object.

On the other hand, the shape and configuration of the foot plate 20 can be changed depending on the presence or absence of the crutches 40 to be described later.

That is, if the footrest 20 is directly contacted with the support surface 90 without the crutches 40, the portion corresponding to the function of the crutches 40 is placed under the footrest 20 abutting the support surface 90 . The footrest 20 without the crutches 40 should be able to absorb an impact that comes into contact with the support surface 90 without slipping against the support surface 90 by contacting the support surface 90 directly.

Therefore, the upper portion of the footrest 20 can be formed of a hard material because it is connected to the body 10, and the lower portion of the footrest 20 is in contact with the support surface 90, so that it absorbs shocks and prevents slippage. .

On the other hand, if the footrest 20 is inserted into the crutches 40 to indirectly contact the supporting surfaces 90, it is easy for the footrests 20 to be inserted into the crutches 40, It is sufficient that the load is transmitted well and the impact that comes into contact with the support surface 90 can be indirectly absorbed.

The foot plate 20 may have a flat plate shape as shown in FIG. 2 so as to have a large contact area with the support surface 90 and may have a load applied from the body 20, As shown in FIG. 4, which can be vertically resilient so as to relieve an impact caused by contact with the upper surface of the foot. However, the shape of the foot plate 20 in the present invention can be variously changed within the technical scope of the present invention.

The material of the footrest 20 may be a rigid plastic material having elasticity or a metal material, and a part of the footrest 20 may be a natural material having elasticity such as rubber material or urethane or synthetic resin.

Further, in the present invention, the material of the footrest 20 need not be limited to a specific material because it needs to be varied depending on its function, structure, or use.

5, when the user supports the lower end of the crutch for the sake of walking, the foot plate 20 is positioned forward of the body 10 in the walking direction of the pedestrian, As a whole, is inclined backward.

In this state, the foot plate 20 rotates downward in the forward direction and upward in the rear direction due to the asymmetric structure, but contacts the elastic member 31 of the rotation guide 30 to be described later and stops after rotating at a predetermined angle.

The suspended pedestal 20 is inclined with respect to the supporting surface so that the pedestal 20 is supported on the supporting surface as shown in Figure 5 (a).

5 (b), the body 10 advances to the step (c) of FIG. 5. When the foot 20 is viewed as a reference, the foot 10 And the body 10 rotates around the hinge 11 connected to the hinge.

Accordingly, the center of gravity moves in the walking direction with respect to the hinge portion 11 of the hinge-connected body 10, which is hinged to the hinge portion 11, so that the hinge portion 11 is rotated at a predetermined angle.

The body 10 is hinged with the center of the foot plate 20 connected to the hinge 11 as a rotation center while the body 10 rotates as a whole, The rotation of the main body 10 can be stably performed on the basis of the center of the foot plate 20 connected to the hinge portion 11. [

In the crutches in which the conventional body and the crutch tip are fixed or orthogonal, when the crutch is inclined during the walking process as shown in FIGS. 5A and 5C, the body may not rotate with the foot plate, ) To maintain the minimum contact area possible.

However, since the body 10 and the footrest 20 according to the present invention can be rotated through the hinge connection of the footrest 20, the user's weight can be uniformly distributed over the widened footrest 20, Sufficient support area can be secured in the whole process of stepping, and the support state can be stably maintained.

The rotation guide 30 may protrude from both sides of the hinge 11 so as to rotate at a predetermined angle before and after the foot plate 20. The rotation guide 30 may be provided with a predetermined thickness The elastic member 31 may be formed.

The rotation guide 30 has two functions in the present invention.

It is possible to limit the rotation of the footrest 20 to a predetermined angle when the footrest 20 rotates with respect to the hinge portion 11 and to absorb the impact transmitted from the front and rear upper surfaces of the footrest 20 or to be elastically elastic.

That is, as shown in FIGS. 2 and 5, the foot plate 20 is asymmetrically rotated about the hinge portion 11 in the forward direction and the rearward direction is rotated upward. However, Thereby restricting the rotation of the footrest 20 at a predetermined angle.

5, the rear upper surface of the footrest 20 and the rear lower surface of the rotation guide 30 are brought into contact with each other. The rotating guide (30) which abuts the elastic member (31) is formed to absorb or store the shock transmitted from the footrest (20).

In particular, the angle formed between the lower surface of the rotation guide 30 and the horizontal surface can be set, adjusted, and applied at various angles in consideration of the user's step width and walking speed.

As shown in Figs. 3 and 6, the front and rear rotation guides 30a and 30b are shown as being symmetrical, but they need not necessarily be symmetrical. This is because the rear rotation guide 30a contacts the rear upper surface of the footrest 20 so as to absorb the impact and the front rotation guide 30b comes into contact with the front upper surface of the footrest 20, The front and rear rotation guides 30a and 30b need to be implemented differently.

Therefore, the front and rear rotation guides 30a and 30b are applied to the elastic members 31a and 31b and the springs 32b and 32b, respectively, which are configured to perform a function suitable for walking.

Particularly, in FIG. 2, the elastic member 31 of the rotation guide 30 is elastically transmitted to or transmitted to the upper and lower surfaces of the foot plate. However, in order to further enhance the elasticity of the elastic member 31, as shown in FIG. 3, the spring members 32a and 32b can have a higher pressing force and a higher elastic force by using the intermediate member.

Further, although not described in detail in the present invention, a damper that performs a damping action may be used in place of the springs 32a and 32b.

The crutches 40 are detachably coupled to the footrest 20 and cover the bottom of the footrest 20 and can absorb a shock due to contact with the support surface.

2 to 4 show a crutches footwear 40 that is mounted on the footrest 20 so that it can be used to further supplement the impact on the support surface 90.

The crutches 40 are provided with an inlet space through which the footrests 20 can be inserted into the crutches 40 so that the footrests 20 can be inserted into the crutches 40.

The crutches 40 are formed with smooth concavities and convexities such as embossing so as not to slip outward on the lower outer circumferential surface in contact with the support surface, .

The crutches 40 may be formed of natural materials or synthetic resins having elasticity such as rubber or urethane.

The locking portion 50 is extended inside the hinge portion 11 and the foot plate 20 so that the foot plate 20 can be rotated or fixed to the body 10 as shown in Figs. A hollow space 51 penetrating is formed and the fixing bar 52 is slid along the space 51 so that it can be locked or unlocked.

The locking bar 50 is unlocked by sliding it upward to slide the fixing bar 52 downward to slide the fixing bar 52 downward to store the locking bar 52 into the hollow space 51, And the locking part 50 is locked so that the footrest 20 is fixed to the body 10 and is kept standing.

Therefore, since the conventional crutches can not stand on their own, the problem of laying them on the floor when they are stored can be solved by the present invention.

The locking portion 50 can be implemented in various other ways within the technical scope of the present invention that allows the footrest 20 to be locked and unlocked to be rotated or fixed with respect to the hinge portion 11 of the body 10. [
