Description

Side arm folding type supination plate

Technical field

The present invention relates to body-building apparatus technical field, especially relate to a kind of side arm folding type supination plate.

Background technology

At present, computer has become important item indispensable in people's work and amusement.But, use computer work or amusement certainly will have influence on the health of people for a long time.This impact is accumulated over a long period, and be on the rise, and not note and the attitude of letting alone all will cause cancerating of physical function in the future.For this reason, market has occurred call the board for lying on back for abdomen back of the body training aids.This board for lying on back not only body-building equipment material, the back manadesma strain of the lumbar muscle strain person that more can releive.According to the study, one day two groups of unlucky dynamic back that will make of receipts amounting to 60 times becomes light.The unlucky dynamic i.e. user of so-called receipts lies low on the service creeper of board for lying on back, and both feet catch on the foot hook frame in front respectively, and both hands are embraced after brain, do sit-up movement.But common board for lying on back is many on folding property to be short of to some extent, and function is comparatively single.

Summary of the invention

The object of this invention is to provide a kind of side arm folding type supination plate, it has and is easy to folding feature.Further, it also has the more feature of function.

The technical solution adopted in the present invention is: side arm folding type supination plate, comprise main frame body, this main frame body is fixed with service creeper, and the front portion of this main frame body be fixed be positioned at this service creeper front on the upside of upper foot hook frame, the underside of forward of described main frame body is hinged with front foot frame by the first hinge, simultaneously, the upper-end part of driving of this front foot frame is provided with pin-and-hole in the front of this first hinge, the bottom of this main frame body is positioned at first locating hole that front is provided with and this pin-and-hole matches of this first hinge, and this pin-and-hole and this first locating hole align the latter two inside can insert one first pin.

The below that the front side portion of described main frame body is positioned at foot hook frame on this is hinged with lower foot hook frame by the second hinge, simultaneously, the rear this main frame body being positioned at this second hinge is provided with the second locating hole, one second pin can be inserted in this second locating hole, and, the middle part of this lower foot hook frame or be connected with extension spring between bottom and this front foot frame.

Described lower foot hook frame is provided with the temporary hole for temporarily depositing this second pin.

The present invention is advantageously: be easy to fold, function is more.The front foot frame of side arm folding type supination plate of the present invention can easily fold backward, can have less occupation of land space.Meanwhile, this service creeper has the lower foot hook frame that can reset, and person taking exercise can carry out the exercise of shank strength by means of this lower foot hook frame, thus makes this board for lying on back have more function.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described:

Fig. 1 is the schematic perspective view (locally) of side arm folding type supination plate in using state of embodiments of the invention;

Fig. 2 is the schematic perspective view (locally) of side arm folding type supination plate at folded state of embodiments of the invention.

Detailed description of the invention

Embodiment, is shown in shown in Fig. 1 and Fig. 2: side arm folding type supination plate, comprises main frame body 10.This main frame body 10 is fixed with service creeper 20, and the front portion of this main frame body 10 be fixed be positioned at this service creeper 20 front on the upside of upper foot hook frame 30.That is, person taking exercise faces upward and lies on this service creeper 20, and ankle portion hooks on this on foot hook frame 30, and both hands embrace head, can carry out sit-up exercise.

Further say, the underside of forward of this main frame body 10 is hinged with front foot frame 40 by the first hinge 41.That is, the front support of this main frame body 10 can get up by this front foot frame 40.Meanwhile, the upper-end part of driving of this front foot frame 40 is provided with pin-and-hole 42 in the front of this first hinge 41, and the bottom of this main frame body 10 is positioned at first locating hole 11 that front is provided with and this pin-and-hole 42 matches of this first hinge 41.What is called matches and refers to aforementioned pin-and-hole 42 and the first locating hole 11 can align, and this pin-and-hole 42 and this first locating hole 11 align the latter two inside and can insert one first pin 43.That is, make this front foot frame 40 prop after inserting this first pin 43, then can support the front portion of this main frame body 10.Meanwhile, when needs carrying or storage, only need this first pin 43 to extract, can by this front foot frame 40 backward, upwards folding and draw close in this main frame body 10 as far as possible, make this board for lying on back have less occupation of land space.

Further say, the below that the front side portion of this main frame body 10 is positioned at foot hook frame 30 on this is hinged with lower foot hook frame 50 by the second hinge 51.Meanwhile, the rear this main frame body 10 being positioned at this second hinge 51 is provided with the second locating hole 12, can insert one second pin 52 in this second locating hole 12.That is, after this second pin 52 is inserted in this second locating hole 12, this second pin 52 can be formed spacing to the upper end of this lower foot hook frame 50, then makes this lower foot hook frame 50 rotate; Otherwise only need to take down this second pin 52, this lower foot hook frame 50 is that is rotatable; And taken down after this second pin 52, this lower foot hook frame 50 also can fold easily.Like this, its ankle portion hooks and also can carry out sit-up exercise on this lower foot hook frame 50 by person taking exercise.And, the middle part of this lower foot hook frame 50 or be connected with extension spring 53 between bottom and this front foot frame 40.That is, person taking exercise also can lie on this service creeper 20, and ankle portion hooks on this lower foot hook frame 50, overcomes the pulling force of this extension spring 53, can carry out the exercise of leg muscle.Certainly, this lower foot hook frame 50 is also provided with the temporary hole 54 for temporarily depositing this second pin 52.That is, when person taking exercise carries out leg muscle exercise or this lower foot hook frame 50 folding, the second pin 52 taken out can be inserted in this temporary hole 54 to avoid it to lose.

The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
