Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that the description is illustrative only, and is not to be construed as limiting the scope of the utility model.
It should be noted that: like reference numerals refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
As shown in fig. 1 to 3, the leg training device 100 includes a main body 10 and two leg rests 20; the main body 10 includes two arms 11 that are coupled to each other and elastically folded and unfolded.
Wherein, the support arm 11 comprises an inner side surface and an outer side surface, and the outer side surface is provided with a support surface 12. The leg rest portion 20 comprises a leg-fitting contact portion 21 and a mounting surface 22 located on the back of the contact portion 21, the contact portion 21 comprises an arc-shaped contact surface s attached to the leg, the mounting surface 22 is arranged opposite to the support surface 12 of the arm 11, and an elastic positioning structure 30 is arranged between the opposite mounting surface 22 and the support surface 12 for positioning, so that the two are abutted against each other and further limited by the elastic positioning structure 30.
Further, after the leg rest portion 20 and the arm 11 are positioned by the elastic positioning structure 30, the leg rest portion 20 is mounted on the arm 11 by the shaft pin 23, and the leg rest portion 20 can rotate around the shaft pin 23. At this time, it should be noted that, in the present embodiment, the shaft pin 23 plays a main role in positioning and connecting the leg-rest portion 20 and the support arm 11, and the leg-rest portion 20 can rotate around the shaft pin 23; without providing a fastening effect for the leg rest portion 20 and the arm 11.
The exerciser needs no additional loose or tight shaft pin 23 when using the device. It is the resilient locating structure 30 that maintains the location of the leg rest portion 20 on the arm 11 in a selected orientation. I.e. to position and angle the resilient positioning structure 30 and more particularly the pivot pin 23, against the leg 20 and the arm 11 in series.
The present invention has the advantage that the leg rest portion 20 is held in the selected orientation by the pivot pin 23 connecting the leg rest portion 20 to the arm 11 while the resilient retention structure 30 limits the rotation of the two.
When the user wants to adjust the orientation of the leg rest portion 20, the user only needs to rotate the leg rest portion 20 to a proper angular orientation, and then the position of the leg rest portion 20 on the rotation plane is switched, and then the positioning is performed by the elastic positioning structure 30. In this case, the shaft pin 23 in the embodiment serves to provide an axis for the leg rest 20 to rotate on the one hand, and to connect the leg rest 20 and the arm 11 on the other hand.
More specifically, a plurality of arc-shaped grooves h1 are distributed on the supporting surface 12 around the pivot pin 23 as the center, and a positioning groove h2 is arranged in the mounting surface 22.
Of course, a plurality of arc-shaped grooves h1 may be distributed on the mounting surface 22 around the pivot pin 23 as the center, and a positioning groove h2 may be provided in the supporting surface 12.
The elastic positioning structure 30 comprises a ball 32 and a spring 31 which are positioned in the positioning groove h2, and the ball 32 falls into one of the arc-shaped grooves h1 to position the leg rest portion 20.
When the leg-rest mechanism is used, a pressing force is applied to the ball 32 during the rotation of the leg-rest portion 20, so that the spring 31 is compressed, the ball 32 can be retracted into the positioning groove h2, and the ball 32 is pushed to move into the next arc-shaped groove h1 by rotating the leg-rest portion 20. When the external force applied to the leg rest 20 is removed, the ball 32 is returned by the resilient force of the spring 31 and cooperates with the curved groove h1 to define the leg rest 20 and the arm 11.
Preferably, as shown in fig. 4, the shaft pin 23 in this embodiment is a screw, and one end of the screw is provided with a knob p 1; the arm 11 is provided with a through hole 13, and a screw hole p2 is provided in the mounting surface 22 of the leg portion 20.
A screw with a knob p1 is screwed through the through hole 13 in the threaded hole p2 of the leg rest 20. The screw is screwed into the screw hole p2, but the leg portion 20 and the arm 11 are not locked, and are positioned by the spring 31 and the ball 32.
Preferably, the number of the arc-shaped grooves h1 on the supporting surface 12 in the present embodiment is 2-10. And the support arm 11 part of the leg rest part 20 is of a flat structure, so that the installation convenience and stability of the leg rest part 20 are improved.
The mounting surface 22 and the support surface 12 are circular surfaces or circular-like surfaces to match the rotation trajectory of the leg rest 20, further improving the smooth feel and visual experience of the exerciser when rotating the leg rest 20.
The present invention is intended to illustrate that the leg rest portion 20 is held in the selected orientation by a pivot pin 23 connection between the leg rest portion 20 and the arm 11 while limiting rotation of the two by a resilient detent structure 30.
When the user wants to adjust the orientation of the leg rest portion 20, the user only needs to rotate the leg rest portion 20 to a proper angular orientation, and then the position of the leg rest portion 20 on the rotation plane is switched, and then the positioning is performed by the elastic positioning structure 30. In this case, the shaft pin 23 in the embodiment serves to provide an axis for the leg rest 20 to rotate on the one hand, and to connect the leg rest 20 and the arm 11 on the other hand.
The present invention has been described above with reference to leg trainers, and the principles and embodiments of the present invention have been described herein with reference to specific examples, which are provided only to assist in understanding the present invention and the core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
