Referring to fig. 1 and 2, an exercise apparatus 200 is provided in accordance with the present invention. The exercise apparatus includes a force source device 100 and a grip lever 170. The force source device 100 includes a frame 110, a servo motor 120, a support 130, and a moving member. In the example shown in fig. 1, the frame 110 is formed by connecting four upright posts 111 and six connecting rods 112. The frame 110 is used to support other components, which may take the form of a frame or other available structure. Each of the columns 111 is provided with a rack 113 extending in the vertical direction.
The support 130 is used for installing the servo motor 120, the moving member and the like. The number of the supporting seats 130 is two, and the supporting seats are arranged at intervals. Each support base 130 includes an L-shaped support plate 131 and a support bracket 132. Two ends of the L-shaped supporting plate 131 are respectively provided with a supporting frame 132. The servo motor 120 is mounted on an L-shaped support plate 131. The L-shaped support plate 131 is provided with a rotatable transmission shaft 121. The servo motor 120 is rotatably provided by driving a transmission shaft 121 via a timing belt 122. The transmission shaft 121 passes through two supporting frames 132 at both ends thereof, respectively, and is provided with a guide gear 123 at an end thereof. The guide gear 123 is engaged with the rack 113. The servo motor 120 drives the guide gear 123 to rotate through the timing belt 122 and the transmission shaft 121. The guide gear 123 may be vertically lifted and lowered along the rack 113 when rotated. A plurality of guide wheels 133 are mounted on the support frame 132. The guide wheel 133 is rotatably provided on the support frame 132 and contacts the column 111. The guide wheels 133 are rollably disposed along the upright 111. The L-shaped support plate 131 is further provided with a cross bar 134. The two ends of the cross bar 134 are respectively connected to the two supporting frames 132. In the example shown, the crossbar 134 is a cylindrical bar.
As shown in fig. 3 to 7, the moving parts are in a box-type structure, the number of the moving parts is two, and the structures are the same. For convenience of description, the first moving member 140 and the second moving member 150 will be named as follows. The structure of the first mover 140 is described below as an example. The first moving member 140 is formed by connecting two side plates 141 through a pin 142. The two side plates 141 are spaced apart. The number of the pins 142 is plural, and the number of the pins can be enough to firmly connect the two side plates. In the example shown in the figures, a first roller 143 is provided on one of the pins 142. The other four pins 142 are provided with second rollers 144. The cross bar 134 passes between the two side plates 141 and through four second rollers 144. Two of the second rollers 144 are located above the crossbar 134 and in contact with the crossbar 134, and two other second rollers 144 are located below the crossbar 134 and in contact with the crossbar 134. Four second rollers 144 grip the crossbar 134. The first roller 143 is coaxially mounted with a first gear 145. The side plate 141 is also mounted with a second gear 146. The second gear 146 is rotatably mounted on the side plate 141. The first gear 145 is meshed with the second gear 146, and the diameter of the first gear 145 is larger than that of the second gear 146. A counterweight 147 is mounted coaxially with the second gear 146. In the example shown, the weight device 147 is a circular block having a selected weight. When the second gear 146 rotates, the counterweight 147 is driven to rotate synchronously.
The second moving member 150 is formed by connecting two side plates 141 through a pin 142. The two side plates 141 are spaced apart. The number of the pins 142 is plural, and the number of the pins can be enough to firmly connect the two side plates. In the example shown in the figures, a first roller 143 is provided on one of the pins 142. The other four pins 142 are provided with second rollers 144. The holding rod 170 passes between the two side plates 141 and through the four second rollers 144. Two of the second rollers 144 are located above the grip lever 170 and are in contact with the grip lever 170, and the other two second rollers 144 are located below the grip lever 170 and are in contact with the grip lever 170. Four second rollers 144 grip the grip lever 170. The first roller 143 is coaxially mounted with a first gear 145. The side plate 141 is also mounted with a second gear 146. The second gear 146 is rotatably mounted on the side plate 141. The first gear 145 is meshed with the second gear 146, and the diameter of the first gear 145 is larger than that of the second gear 146. A counterweight 147 is mounted coaxially with the second gear 146. In the example shown, the weight device 147 is a circular block having a selected weight. When the second gear 146 rotates, the counterweight 147 is driven to rotate synchronously.
The first moving member 140 and the second moving member 150 are vertically disposed and connected by a connecting member 160. The connecting member 160 has an upper end connected to the second moving member 150 and a lower end connected to the first moving member 140. The connecting member 160 is used to connect the first moving member 140 and the second moving member 150, and its specific structure may be any feasible structure, such as a connecting rod, a connecting plate, etc.
The axis of the first roller 143, the axis of the second roller 144, the axis of the first gear 145, and the axis of the second gear 146 on the second moving member 150 are perpendicular to the axis of the first roller 143, the axis of the second roller 144, the axis of the first gear 145, and the axis of the second gear 146, respectively, on the first moving member 140 disposed therebelow. The grip lever 170 is inserted between the side plates 141 of the second moving member located above at both ends thereof, respectively. Four second rollers 144 on the upper mover grip the grip lever 170. The first roller 143 on the second moving member above contacts the holding rod 170 and rolls along the holding rod 170, and the first roller 143 moves relative to the holding rod 170 along the axial direction of the holding rod 170 when rolling.
When the exercise device of the present invention is used for exercise, the grip lever 170 is lifted or pulled upward with force, and the grip lever 170 drives the moving member to move upward. The servo motor 120 outputs a force for moving the support base 130 downward through the timing belt 122, the transmission shaft 121, and the guide gear 123, and the force constitutes a resistance to upward movement of the grip lever 170. The effect of this resistance corresponds to the weight of the barbell when the barbell is used for exercise. During use of the present invention, the grip 170 will inevitably move axially along the crossbar 134 or in a direction perpendicular to the page, i.e., the grip 170. When the holding rod 170 moves along the axial direction of the cross bar 134, the two moving parts are driven to move along the axial direction of the cross bar 134. The first roller 143 and the second roller 144 on the first moving member 140 both roll along the axial direction of the cross bar 134 under the force of the holding rod 170. The first roller 143 of the first moving member 140 contacts the crossbar 134 to have a friction force that rotates the first roller 143 of the first moving member 140. Since the first gear 145 has a larger diameter than the second gear 146, when the first gear 145 rotates one revolution, the second gear 146 will rotate more than one revolution, the specific rotational travel of which depends on the ratio of the diameters of the first gear 145 and the second gear 146. When the holding rod 170 moves along the axial direction, the first roller 143, the first gear 145 and the second gear 146 on the second moving member 150 are driven to rotate, so as to drive the counterweight device 147 to rotate. Therefore, when the grip lever 170 is lifted for exercise, it is necessary to have a sufficient driving force to rotate the weight means 147 on the first moving member 140 and the weight means 147 on the second moving member 150, both when the moving member moves axially along the crossbar 134 and when the grip lever 170 moves axially itself. If the weight 147 on the first moving member 140 and the weight 147 on the second moving member 150 are rotated, it is necessary for the exerciser to apply a certain force to stop the rotation of the two moving members. Therefore, the structure of the invention can ensure that the resistance to be overcome exists in two directions of the moving part on the horizontal direction, so that the structure of the invention which uses the moving part nearby can simulate the moving effect of the disc and has good using feeling.
In the above embodiment, the cross bar 134 is one embodiment of a horizontal guiding device, which is used for guiding the moving member when moving horizontally, and other available structures such as a cross plate, a guiding tube, etc. may be used instead. The weight 147 is one of the embodiments of the counterweight device, which is to maintain a large inertia, and it is only necessary to have a set weight, so that it may be replaced by other available structures. The inertia maintaining apparatus in this embodiment includes a first roller, a first gear, a second gear, and a counterweight, which is used to maintain a large inertia, and some structures such as the first gear and the second gear may be omitted. Other structures can be adopted to replace part of the parts, such as synchronous belt assemblies and chain assemblies to replace the first gear and the second gear. The first roller realizes that the transverse linear movement of the moving member is converted into the rotation of the balancing weight, and as one embodiment of the movement conversion device, a structure with similar function can be adopted for replacement. The diameters of the first gear and the second gear are different, so that the stroke is amplified, namely, the first roller rotates for one circle, and the balancing weight rotates for more than one circle. The first gear and the second gear are used as one embodiment of the stroke amplifying device, and can also adopt chain wheels and synchronous pulleys with different diameters to achieve the same function.
The force source device of the exercise equipment and the exercise equipment of the invention utilize the inertia holding device to help the moving piece to hold the inertia moving in the horizontal direction. The moving accessory of the present invention has greater inertia, and requires greater force in the horizontal direction from rest to motion, and greater force from motion to rest, than a configuration using only the exercise accessory. Therefore, even if the barbell piece is not arranged, the force source device can realize a state similar to the state of lifting the barbell, so that an exerciser feels the sensation of lifting the barbell, the experience is good in the exercise process, and the use effect is better. The invention adopts the motion conversion device to convert the linear motion of the body-building accessory into the rotation of the counterweight device, so that the invention can simulate the effect of lifting the barbell and has novel use mode. By using the travel amplifying device, the use effect of the heavier disc can be simulated by using the lighter weight device, the production cost is low, and the whole weight of the device is small.
The above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions or improvements within the spirit of the present invention are intended to be covered by the claims of the present invention.
