The at least one front support is suitable for being pushed by the torso when the torso moves forward relative to the legs, and drives the at least one connecting member to move from the initial position to the actuating position via the connecting members.

The effect of the present model is that: when the human body makes the operating units respectively positioned on the outside of the legs through the wearing unit, when bending over and allowing the torso to push against the at least one front support, due to the The connecting relationship between the connecting parts and the connecting parts makes the dampers accumulatively support the torso due to the moving of the connecting parts to the actuation position, and even help the torso restore the auxiliary force of standing upright, so that it can indeed respond to bending The action of waist work produces auxiliary effect.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

Referring to Fig. 1 , it is a first embodiment of a novel torso labor-saving device. This first embodiment is suitable for wearing on a human body 1, which includes a torso 11 and two legs 12 connected to the lower part of the torso 11. . Wherein, the torso 11 includes a chest 111 facing forward, two shoulders 112 separated by left and right shoulders, and a back 113 opposite to the chest 111 (marked in FIG. 4 ). The first embodiment includes two operating units 2 adapted to be arranged outside the legs 12 of the human body 1 , and a wearing unit 3 connected to the operating units 2 and adapted to be worn on the human body 1 .

Referring to FIG. 2 , each operating unit 2 includes a body 21 surrounding and defining an accommodating space 210 , a wheel 22 passing through the body 21 and capable of rotating relative to the body 21 along a rotation axis, and a connection On the runner 22 and a joint 23 that can rotate together with the runner 22, a damper 24 adjacent to the body 21, and an end that is wound around the runner 22 and away from the runner 22 is connected The drag cable 25 of the damper 24. Wherein, a part of each of the runners 22 is accommodated in the accommodation space 210 on the same side, and the corresponding traction rope 25 is wound around the individual runners 22 in the individual accommodation spaces 210, so as to The traction cables 25 are protected by the bodies 21 to ensure that the parts of the traction cables 25 wound around the runners 22 will not be accidentally touched and affect normal operation. Each damper 24 has a cylinder body 241 surrounding and defining a chamber 240, a spring 242 disposed in the chamber 240, and an end against the spring 242 away from the individual body 21, And it is connected to the individual traction cables 25 to compress the spring 242 to generate the compression member 243 of the auxiliary force. Specifically, each of the pulling cables 25 extends into the cavity 240 on the same side, passes through the respective spring 242 in the axial direction, and then connects to the compression member 243 . Therefore, each of the traction cables 25 can pull the respective compression member 243, thereby compressing the corresponding spring 242 to accumulate elastic restoring force.

Referring to Fig. 3 and cooperating with Fig. 2, the connecting member 23 of each operating unit 2 can be in an initial position, and one can drive the individual runners 22 to rotate so that the corresponding traction cables 25 apply force to the individual dampers device 24, and make the damper 24 move between actuating positions where an auxiliary force is generated. That is to say, when each of the connecting parts 23 moves to the actuation position, the individual runners 22 will be rotated and a part of the traction rope 25 that is wound around the runners 22 will be rolled, thereby making the runners 22 rotate. The traction cable 25 pulls the connected compression member 243 . At this time, since the spring 242 on the same side is compressed, an elastic restoration force will be accumulated to restore the connecting member 23 to the initial position.

Referring to FIG. 4 and in conjunction with FIG. 1, the wearing unit 3 is suitable for being worn by the human body 1, so as to position the operating units 2 on the human body 1 in a direction extending left and right with the axis of rotation, that is, roughly located on the human body 1. The outer sides of the legs 12 of the human body 1 . The wearing unit 3 includes two connecting parts 31 respectively connected to the connecting parts 23, a front support 32 connected between the connecting parts 31 and suitable for pressing against the chest 111 of the torso 11, and two connecting parts respectively connected to the chest 111 of the torso 11. The extensions 33 at the bottom of the dampers 24, two leg supports 34 respectively connected to the extensions 33 and adapted to be pressed against the front sides of the legs 12 of the human body 1, one connected to the front support 32 and The shoulder-back module 37 between the operating units 2, and two waist belts 38 respectively connected to the front side and the rear side of the operating units 2 and adapted to surround the torso 11 of the human body 1 together. Wherein, the shoulder module 37 has two shoulder straps 371 that are respectively connected to the front holder 32 and extend away from the end of the front holder 32 toward each other, and one is connected to the ends of the shoulder straps 371 away from the front holder 32 and is suitable for use. The cross piece 372 abutting against the back 113 and two positioning belts 373 connected to the cross piece 372 and connected to the operating units 2 at the ends away from the cross piece 372 . The shoulder straps 371 and the positioning straps 373 are intersected on the back 113 of the human body 1 by the shoulder module 37, which can generate inward traction to the operating units 2, thereby preventing the operating units from 2 to shake outwards, so that the operating units 2 can be maintained at the most suitable operating positions relative to the human body 1 .

Referring to FIG. 5 together with FIG. 1 and FIG. 3 , the action of the human body 1 bending down repeatedly to lift objects after wearing the first embodiment is illustrated as an example. When the torso 11 of the human body 1 bends forward, the chest 111 directly exerts force on the front support 32, and cooperates with the supporting effect of the leg supports 34 on the legs 12, it can be directly connected to the front support. The connecting parts 31 of 32 drive the connecting parts 23 to rotate forward together with the runners 22 around the axis of rotation, that is, to move the connecting parts 23 from the initial position to the actuating position. During the process, the rotation of the runners 22 will pull the traction cables 25 , and then pull the compression members 243 to compress the springs 242 , thereby accumulating elastic restoring force. Through the elastic restoring force accumulated by the springs 242, when the torso 11 of the human body 1 bends to carry an object, in the process of making the torso 11 stand upright again, it will receive the upward auxiliary effect of the elastic restoring force, In this way, the burden caused by the movements that originally required repeated stretching of the muscles around the lower back can be reduced.

Referring to FIG. 6 together with FIG. 1 and FIG. 3 , it will be described by referring to the case where the torso 11 of the human body 1 is bent and then continues to perform operations such as rice planting while maintaining the bending action. Similarly, when the human body 1 bends down, that is, the chest 111 is pushed against the front support 32 , the springs 242 will also accumulate the elastic restoring force. At this time, although the human body 1 is kept in the bending action, since the trunk 11 bends forward in the same direction as the gravitational force, the elastic restoring force against the gravitational force will also pass through these The connecting parts 23 and the connecting parts 31 are transferred to the front bracket 32 to support the chest 111 of the human body 1, so that the burden on the human body 1 during bending can be reduced.

It is worth noting that in the first embodiment, the auxiliary effect is achieved through the operating units 2 respectively located on the left and right sides, although the front bracket 32 is probably driven by the relative moving elements, but these The lower end of the operating unit 2 indeed produces a supporting effect through the separated leg pieces 34 . Therefore, when the human body 1 is working, even if it is necessary to perform actions that are not completely symmetrical on the left and right sides due to the needs of the action of the work, the operating units 2 can operate independently and properly because they operate independently and are not linked together. respond. For example, when the human body 1 bends forward and backward in a forward and backward lunge as shown in FIG. 7, the operating units 2 (only one of them is shown in FIG. The movement difference of these connecting parts 23 operates separately under the situation of different rotation angles, so that the movements of the left and right sides of the human body 1 are not mutually restricted, thereby optimizing the flexibility of activities when wearing the first embodiment.

Referring to FIG. 8 , it is a second embodiment of the new trunk labor-saving device. The difference between this second embodiment and the first embodiment is that the wearing unit 3 includes two shoulders 112 respectively The front support 32 . Compared with the first embodiment, the second embodiment uses the shoulders 112 to evenly share the pushing force against the front supports 32. In addition to dispersing the pushing force, it can also drive the operating units. 2 operation, reach the same effect as this first embodiment and produce auxiliary force when bending over.

To sum up, the novel torso labor-saving device can drive the traction cables 25 through the co-rotation of the connecting parts 23 and the runners 22 in response to the bending action of the human body 1 so that the springs 242 accumulates the elastic recovery force that makes the torso 11 of the human body 1 go upward, so as to generate auxiliary force when the torso 11 stands upright again for the bending action, or maintain the supporting force when bending over. Therefore, can really reach the purpose of this novelty.
