Abstract
The utility model discloses a tensile force supine board which comprises a front frame and a rear frame connected together; a foot hook and a supporting rod are arranged on the front frame; a lying board is arranged on the rear frame; and the upper part of the front frame is connected with a tensile force device. After optimization, the tensile force device comprises a spring and a handle; one end of the spring is connected with the handle, and the other end of the spring is connected with the front frame; and the tensile force device is connected with the front frame through movable buckles. The tensile force supine board has the advantage that an exerciser can do multiple items of exercise simultaneously, so that the exercise efficiency is higher, and the effect is better.
Description
Technical field
The present invention relates to the body-building apparatus technical field, especially relate to a kind of pulling force board for lying on back.
Background technology
Board for lying on back is body-building apparatus commonly used at present.General, board for lying on back comprises side arm and the after-frame that links together, and side arm is provided with that pin colludes and strut, and after-frame is provided with service creeper.Like this, the person taking exercise lies on the service creeper upside down, and ankle section is colluding pin and colluding, and thigh is subject to the support of strut, can carry out easily sit-up exercise.In order to increase the function of this board for lying on back, people have connected stay cord in the place ahead of board for lying on back, are used for carrying out pulling force and take exercise.But the person taking exercise only can select separately an exercising way at one time.That is: perhaps carry out sit-ups, perhaps carry out pulling force and take exercise, thereby exercise efficient is not high.Therefore be necessary to be improved.
Summary of the invention
Deficiency for above-mentioned prior art exists the purpose of this invention is to provide a kind of pulling force board for lying on back, and it has the person taking exercise can carry out multinomial exercise simultaneously, thereby exercise efficient is higher, and effect is characteristics preferably.
To achieve these goals, the technical solution adopted in the present invention is: the pulling force board for lying on back, comprise the side arm and the after-frame that link together, and side arm is provided with that pin colludes and strut, and after-frame is provided with service creeper, and the top of described side arm is connected with chest expander.
Described chest expander comprises spring and handle, and an end connecting handle of this spring, the other end connect side arm.
Described chest expander is connected knot that can be undone by a pull to be realized connecting with side arm.
After adopting said structure, the present invention is compared with existing technology the advantage that has and is: 1, the person taking exercise can carry out multinomial exercise simultaneously, thereby exercise efficient is higher, and effect is better.Pulling force board for lying on back of the present invention arranges chest expander on side arm top, and during person taking exercise's sit-ups, because the person taking exercise lies on the service creeper, hand can grip chest expander simultaneously, takes exercise thereby carry out pulling force.That is, the person taking exercise has carried out two exercises simultaneously, and exercise efficient is higher.2, assembling is simple, easy to use.Chest expander is connected with side arm by knot that can be undone by a pull, has made things convenient for the demolition, installation of chest expander.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the perspective view of embodiments of the invention;
Fig. 2 is the perspective view of knot that can be undone by a pull of the present invention.
The specific embodiment
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, see illustrated in figures 1 and 2: the pulling force board for lying on back comprises the side arm 11 and the after-frame 12 that link together.Are connected with after-frame such as, side arm 11 and are " people " font and connect.Wherein, side arm 11 is provided with strut 30 and pin colludes 20, and after-frame 12 is provided with service creeper 40.In order to increase the function of this board for lying on back, and improve person taking exercise's exercise efficient, the top of side arm 11 is connected with chest expander 50.This chest expander 50 can be connected on the side arm 11 by knot that can be undone by a pull 511.Obviously, adopt after the knot that can be undone by a pull 511, be convenient to the demolition, installation of chest expander 50.Certainly, chest expander 50 preferably is connected in the top of strut 30.
Chest expander 50 can be taked multiple common mode.Optimize, this chest expander 50 comprises spring 51 and handle 52.At this moment, an end connecting handle 52 of spring 51, the other end connect side arm 11.At this moment, knot that can be undone by a pull 511 is positioned at the end of spring 51.
Using method of the present invention: the person taking exercise lies on the service creeper 40, and hand grips handle 52, and ankle section is colluding pin and colluding 20, and thigh is subject to the support of strut 30, carries out pulling force and take exercise in sit-ups.Certainly, the person taking exercise also can select separately sit-ups or pulling force to take exercise.
