Description

M265072 4. Creation Instructions (1) [Technical Field of New Type] This creation relates to the improvement of sports fitness equipment, and aims to provide a sit-up exercise aid that can effectively assist users in sit-up exercises. [Previous technology] In a busy life, the average office worker can hardly spare time for outdoor sports, so most of them can only use the trivial time after work to do some simple limb stretching exercises, or use the time before bedtime to do Some simple supine exercises to stretch the bones and muscles and increase the body's metabolic function. Among them, when doing sit-ups, because the body's center of gravity changes with the exercise posture, in a state where others can help fix your feet, you can make The sit-up exercise is carried out more smoothly, but in reality, there is not a suitable person who can assist the sit-up exercise at any time, so that there is an assist device to assist the user in the sit-up exercise. As shown in the first figure, it is a conventional auxiliary structure. This auxiliary device is provided with a baseboard 1 1 on which a user lies on a base frame 10, and the base frame 10 corresponds to the baseboard. A fixed foot 12 with a considerable height is provided straight at the rear end of 1 1. A cross bar 1 3 for hooking the user's footboard is provided at an appropriate height of the fixed foot 12, and the user is riding on the bedboard 1. 1 is near one end of the fixed foot bar 12 and fixes the feet by bending the feet and hooking the foot board on the cross bar 13 to achieve the purpose of assisting the user to perform supine motion.

M265072 IV. Creation instructions (2) However, the slanting angle of the bedplate 1 1 of the conventional auxiliary device is too large and cannot be adjusted. For users with insufficient waist strength, it is impossible to lift the body toward the fixed foot 12 And, besides the functions that can be used to fix the user's feet, there are no other functions that can help the user perform the supine team exercise. For ordinary users, it still requires a large amount of strength to lift the body. Therefore, the practicality is not as ideal as expected, and it is more likely to cause sports injuries to the user. [New content] The creation of "Structure Improvement of the Sit-up Sit-up Exercise Aid" is based on a base frame equipped with crossbars for users to fix their feet, grips for users to hold with both hands, and A seat supporting the user's body; wherein, the cross bar is arranged at one end of the base frame, and the seat is arranged at the middle position of the base frame, and the grip is connected with a motor through a tether and a reel. , The user can sit on the seat, and hold the grip and press the down switch, so that the motor releases the tether, so that the body slowly lays back on the lying board, and when the up switch is pressed, the motor The tether is rolled up and the grip is pulled toward the base frame, so as to generate a pulling force for assisting the user to assist the user in performing sit-ups. Furthermore, a reclining plate with an adjustable inclination angle is further provided on the other side of the seat corresponding to the cross bar, so that the reclining plate can be used as a structure to support the user's body, and can be used by the user according to his own waist force. Adjusting the inclination angle of the lying plate 'even the lying plate is completely flat' to meet the needs of the world, highlighting the practicability and applicability of the aid.

The user can sit on the seat 20 and hold the grip 30 and press the down switch 3 0 2 to release the motor from the tether 3 1 and let the body slowly lie back on the lying board 21, and when When the up switch 3 0 1 is held down, the tether 31 is rolled up by the motor 40 and the grip 30 is pulled toward the crossbar 13 to produce a pull-up effect for the user. To achieve the purpose of assisting users to perform sit-ups. Moreover, as shown in the third figure, the base frame 10 of this creation is provided with a fixed foot 12 with an appropriate height at one end, and the other end of the base frame 10 corresponding to the fixed foot 12 , And in the middle of the base frame 10

M265072 4. Creation instructions (5) There are foldable collapsible folding feet 14 at the position, so that the base frame 10 can be supported to a height sufficient to configure the motor 40; as shown in Figures 7 and 8 As shown in the figure, the folding foot 14 is pivotally set at a predetermined position on the base frame 10, and a positioning hole 15 at an angle of ninety degrees is provided on the periphery of the pivot. The folding foot 14 is according to the activity. The positioning holes 15 selected by the pins 16 are changed to reach the extended or folded state, so that when necessary, all the folding feet 14 of the base frame 10 can be folded to increase the convenience of the storage of the auxiliary device. Sex. As mentioned above, this creation provides a better and feasible sit-up exercise aid, and filed a new patent application in accordance with the law; however, the above implementation descriptions and diagrams are those of the preferred embodiment of this creation and are not In this way, the limitation of this creation is to be similar to the structure, installation, features, etc. of this creation, which should be within the scope of the creation purpose of this creation and the scope of patent application.
