Description

Torso stretching equipment

The present invention relates to a fitness apparatus, and more particularly to a torso stretching apparatus for a user to stretch a torso and train an upper limb.

Maintaining a sitting posture for a long period of time can cause a static load on the body. No matter how correct the sitting posture is, it will cause muscle fatigue and impede blood circulation. The too close to the spine joint is also easy to oppress the nerve. Therefore, the sedentary person should appropriately arrange the time to change the posture. You should even get up and do stretching exercises to relieve stress and fatigue on your body.

However, for people who are inconvenient in lower limbs and need to use a wheelchair to move, getting up and stretching can be a problem, but it is easy to have a bad influence on health by stretching the muscles for a long time.

Therefore, how to provide a device that can help the user to stretch the trunk is worthy of consideration by those in the field.

One of the primary objects of the present invention is to provide a device that can assist a user in performing a torso extension.

Another primary object of the present invention is to provide an exercise device that is useful for training the upper limb muscles.

In order to achieve the foregoing and other objects, the present invention provides a torso extension device including a support frame, a horizontal axis, a two-rotor arm, two tie rods, and a linkage mechanism, wherein the horizontal axis is rotatably disposed on the support frame. The two arms are disposed on the horizontal axis and are rotatable relative to the support frame along the horizontal axis, and the two arms are used to support the user's armpits, and the two tie rods are respectively supported by a first rotation axis Rotatingly disposed on the support frame and respectively located above the two spiral arms, the two pull rods are used for driving the upper limbs of the user, and the two linkage mechanisms are respectively disposed on the horizontal axis and one of the pull rods In the meantime, the arm and the tie rod are in a rotationally interlocking relationship.

Therefore, when the user drives the lever on the upper limb, the arm is driven to lift the user to kneel, so that the user can lift the upper body by the force of the upper limb, and the trunk can be stretched while training the muscle. Force, help users with inconvenient lower limbs maintain a healthy posture.

The two interlocking mechanisms 50 are respectively disposed between the two ends of the horizontal shaft 20 and one of the pull rods 40, so that the swing arm 30 and the pull rod 40 are in a rotationally interlocking relationship. Possible embodiments of the linkage mechanism 50 include a link group and a toothed disc set. The combination of the chain group, the other linkage group or the plurality of linkage groups, and in the preferred embodiment, each of the linkage mechanisms 50 includes a first turntable 51 fixed to the horizontal axis 20, and one fixed to the first The second turntable 52 of the rotating shaft 41 and a connecting rod 53 are connected to the first and second rotating wheels 51, 52; the first and second rotating wheels 51, 52 of the embodiment are in the shape of a fan, but the shape of the rotating plate is not For example, when the user drives the pull rod 40 downward, the pull rod 40 can drive the first turntable 51 to rotate via the first rotating shaft 41, and the first turntable 51 is connected again. The rod 53 drives the second turntable 52 to rotate, and the second turntable 52 drives the horizontal shaft 20 to rotate. At this time, the swing arm 30 can be lifted up to support the user's armpit, so that the upper body of the user receives an upward traction force. The user's torso is stretched.

In order to adapt to the body length of different users, the initial relative angle of the arm 30 and the tie rod 40 can be designed to have an adjustable function, for example, one of the first and second turntables 51, 52 forms a plurality of indexing holes 54 for The connecting rod 53 is inserted, and the connecting rod 53 is inserted into the different indexing holes 54 to achieve the function of adjusting the initial relative angle; or the interlocking mechanism 50 further includes two latches 55 and two cranks 56, and each of the cranks 56 is provided. It is disposed on the horizontal axis 20 or one of the first rotating shafts 41, and forms a jack 562 at one of the free ends 561 of the crank 56, and can be inserted into the jack 562 and different indexing holes by inserting the latch 55 into the jack 562. 54 to adjust the initial relative angle of the arm 30 and the tie rod 40. The design of any of the two types of interlocking mechanisms 50 described above can separately achieve the function of adjusting the initial relative angle. Therefore, the plurality of indexing holes 54 can be provided only for the first and second rotating disks 51 and 52. Of course, the mechanism for adjusting the initial relative angle is not limited to that shown in this embodiment, and it is also practical to form a screw portion having a screw hole in one of the first and second rotating disks 51 and 52 (not shown). And forming a thread (not shown) on the connecting rod 53 to penetrate the screw hole, thereby changing the relative distance between the first and second rotating wheels 51, 52 when the screwing portion is rotated, and also adjusting The purpose of the aforementioned initial relative angle.

Referring to Figures 1 and 4, in order to let the user know the current state of motion, the torso stretching device 1 of the present invention may further include a sensor for sensing the motion state of the horizontal axis 20. 60. A screen 70 disposed on the support frame 10 and connected to the sensor 60. The motion state includes a rotation angle, a displacement, a torque value, and the like of the horizontal axis 20. For example, the sensor 60 It can be a resistive angle sensing component, and can be used to sense the angular change of the horizontal axis 20, and output and display the sensed signal on the screen 70; of course, the sensor suitable for the present invention is not limited thereto. .

The different states of use of the preferred embodiment are illustrated below by way of illustration.

Referring to FIGS. 5 and 6, the extension arm 34 of the present embodiment can adjust the spacing between the cushion units 35 by rotating relative to the fixing base 31.
