Description
Technical field
The present invention relates to body-building apparatus technical field, especially relate to a kind of board for lying on back with leg exerciser.
Background technology
As modal a kind of body-building apparatus, board for lying on back comprises the L-shaped side arm that links together and after-frame, and the front portion of this side arm top or this after-frame is provided with support bar.Meanwhile, have a pin raker to be fixed on the bottom of a connecting rod, the upper end of this connecting rod is articulated in the middle part of this side arm, and this connecting rod also has the trend resetted downwards.And this after-frame is provided with service creeper, this service creeper is usually in middle convex arc.Like this, person taking exercise faces upward and lies on this service creeper, and thigh is subject to the support of this support bar, and ankle portion hooks on this pin raker, repeatedly lies down and stands up, can carry out sit-up exercise; Or person taking exercise firmly triggers this pin raker, can perform physical exercise to leg muscle.Its defect is: 1, the restoring force of connecting rod reset is constant, thus cannot meet the needs of the person taking exercise with different leg power.That is, range of application is narrower.2, because person taking exercise is when standing up, completely by means of the waist abdomen strength of self, for the person taking exercise that some waist abdomen strength are more weak, comparatively difficulty of standing up, is easy to make it lose the interest of carrying out sit-up exercise.
Summary of the invention
The object of this invention is to provide a kind of board for lying on back with leg exerciser, it has the needs that can meet the person taking exercise with different leg power, the feature that range of application is wider then.Further, it also has the feature that the person taking exercise that can meet different power of waist carries out sit-up exercise.
The technical solution adopted in the present invention is: the board for lying on back with leg exerciser, comprise the side arm and after-frame that link together, the front portion of this side arm top or this after-frame is provided with support bar, simultaneously, a pin raker is had to be fixed on the bottom of a connecting rod, the upper end of this connecting rod is articulated in the middle part of this side arm, and, this after-frame is provided with service creeper, there are the two ends of a torsion spring to hook respectively on the top of this connecting rod and the middle part of this side arm, have the two ends of an extension spring to hook respectively on the bottom of this connecting rod and the bottom of this side arm.
The two ends of described support bar are connected to an elastic drag rope, and the other end of these 2 elastic drag ropes is provided with handle.
The present invention is advantageously:
1, the needs of the person taking exercise with different leg power can be met.The board for lying on back with leg exerciser of the present invention in use, can torsion spring be acted on connecting rod, also can extension spring be acted on connecting rod, or this torsion spring and extension spring are acted on this connecting rod simultaneously, thus make this connecting rod obtain the restoring force of different size, to meet the needs with the person taking exercise of different leg power.
The person taking exercise that 2, can meet different power of waist carries out sit-up exercise.Person taking exercise use of the present invention there is the board for lying on back of leg exerciser and lie down time, hand can haul handle, thus the pulling force of elastic drag rope can be subject to when standing up, even if then waist abdomen strength slightly weak person also can stand up easily, add confidence and enjoyment for it carries out sit-up exercise.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of embodiments of the invention.
Detailed description of the invention
Embodiment, as shown in Figure 1: the board for lying on back with leg exerciser, comprises the L-shaped side arm 11 that links together and after-frame 12.Certainly, the bottom of this side arm 11 and this after-frame 12 all arranges feet.Wherein, the front portion of this side arm 11 top or this after-frame 12 is provided with support bar 20; Have a pin raker 30 to be fixed on the bottom of a connecting rod 31, the upper end of this connecting rod 31 is articulated in the middle part of this side arm 11.That is, this pin raker 30 can with the connecting axle of the upper end of this connecting rod 31 and this side arm 11 for rotating shaft rotates.And this after-frame 12 is provided with service creeper 40.This service creeper more than 40 is in middle convex arc.
Further say have the two ends of a torsion spring 50 to hook respectively on the middle part of the top of this connecting rod 31 with this side arm 11, have the two ends of an extension spring 60 to hook respectively on the bottom of the bottom of this connecting rod 31 with this side arm 11.Obviously, this torsion spring 50 and this extension spring 60 are this connecting rod 31 provides the restoring force be rotated down, and this torsion spring 50 and this extension spring 60 all can disassemble easily.Like this, person taking exercise is when carrying out leg power and taking exercise, can separately this torsion spring 50 be acted on this connecting rod 31, also can separately this extension spring 60 be acted on this connecting rod 31, or this torsion spring 50 and this extension spring 60 are acted on this connecting rod 31 simultaneously, thus make this connecting rod 31 obtain the restoring force of different size, to meet the needs with the person taking exercise of different leg power.
Further say, the two ends of this support bar 20 are connected to an elastic drag rope 70, and the other end of these 2 elastic drag ropes 70 is provided with handle 71.Like this, when person taking exercise lies down using this board for lying on back with leg exerciser to carry out sit-up exercise, hand can haul these 2 handles 71, thus can be subject to the pulling force of these 2 elastic drag ropes 70 when standing up, even if then waist abdomen strength slightly weak person also can stand up easily.
To sum up, this board for lying on back with leg exerciser has the stronger scope of application.
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.
