Description
- 1. Field of the Invention
- The present invention relates to an exercise device, in particular to a torsion-type exercise device which can be easily adjusted to provide different bending and twisting strength.
- 2. Description of the Related Art
- With reference to FIG. 1 showing the conventional torsion-type exercise device, it can be noted that the two ends of a spring C is secured to the left and right levers A,B, respectively. The left and right levers A,B, upon gripping and application of a bending action against the resistant force of the spring therebetween, consequently achieves an exercise effect directed to the two upper limbs of the user (including the palm, elbows, arms and chest). Such an exercise device is of simple structure, easy to use, and is of small bulk making it easy to carry and store, and is low cost and, as such, is a very common device. However, such device does not provide the function of adjustment of the bending strength. The suitability of such device to children, men and women and old people is limited.
- Accordingly, an object of the present invention is to provide a torsion-type exercise device which can be easily adjusted to suit children, women, men and old people who have different strength.
- To achieve the above object, the present invention provides an exercise device which comprises:
- left and right hand levers each having a rod and a pivot seat fixedly attached to one end of said rod,
- a pull member consisting of a stem and a block, said stem being vertically disposed in the center of said block,
- a torsion-adjusting mechanism sleeved onto said stem and including a connecting member for pivotal connection to said pivot seat; and
- two arms, one of which has two ends pivotally connected to one end of said block and said pivot seat of said left hand lever, respectively, and the other of which has two ends pivotally connected to the other end of said block and said pivot seat of said right hand lever.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, in which:
- FIG. 1 is a operational view of the conventional torsion-type exercise device;
- FIG. 2 is an exploded perspective view of the present invention;
- FIG. 3 shows the assembled form of the present invention;
- FIG. 4 is a cross-sectional view taken from line A-A of FIG. 3 of the present invention prior to use;
- FIG. 5 shows the left and right hand levers of the exercise device of the present invention as they are bent from the position shown in FIG. 4; and
- FIG. 6 shows the left and right hand levers of the exercise device of the present invention when fully bent into a side-by-side position from the position shown in FIG. 4.
- With reference to FIG. 2 and FIG. 3, the present invention, according to a preferred embodiment, comprises a
left hand lever 10, aright hand lever 20, apull member 30, twoarms adjusting mechanism 50. - The left hand lever10 and
right hand lever 20 are of completely the same structure and shape and thus, only theleft hand lever 10 will be described herein for simplicity's sake. Theleft hand lever 10 includes arod 101 and apivot seat 102. One end of therod 101 is sheathed with a grippingsleeve 100, while the other end is fixed to thepivot seat 102. Thepivot seat 102 has an L-shape bent member 103 and aprojection 104. Thebent member 103 is provided with a through-hole 105 at one end thereof, and thebent member 103 is provided with a threadedhole 106. Abore 107 is provided on theprojection 104 which is alignment with the threadedhole 106, and aspace 108 is defined between thebent member 103 and theprojection 104. - The torsion-
adjusting mechanism 50 includes anadjustment nut 501, aspring 502, asupport disk 503 and a connectingmember 504. A threadedbore 505 is provided in the center of the top portion of theadjustment nut 501, and through-holes support disk 503 and connectingmember 504, respectively. Therods member 504 provide for insertion into the through-holes bent members bolts holes - The
pull member 30 consists of astem 301 havingthreads 300 at the top portion thereof and ablock 302. Thestem 301 is vertically disposed in the center of theblock 302. From the two ends of theblock 302 each extend a pair ofwalls spaces walls hole 305 and a threadedhole 306, respectively, while the other pair ofwalls hole 307 and a threadedhole 308, respectively. Thestem 301 is passed through the through-hole 507 of the connectingmember 504, the through-hole 506 of thesupport disk 503 and the center of thespring 502, in that order, and is secured to the threadedbore 505 of theadjustment nut 501. The two terminal ends of each arm 40(41) are each provided withapertures 401,402(411,412), in which the top end of onearm 40 is inserted in thespace 108 while the bottom end is inserted in thespace 303, and the top end of theother arm 41 is inserted in thespace 208 while the bottom end is inserted in thespace 304. Abolt 413 is passed through thebore 107 and theaperture 401 of thearm 40, and threadedly locked into the threadedhole 106, while abolt 414 is passed through thebore 207 and theaperture 411 of theother arm 41 and threadedly locked into the threadedhole 206. Abolt 415 is passed through the through-hole 305 andaperture 402 of thearm 40 and threadedly locked into the threadedhole 306, while abolt 416 is passed through the through-hole 307 andaperture 412 of theother arm 41 and threadedly locked into the threadedhole 308. - Thus, when the
adjustment nut 501 is appropriately tightened by rotation, thecompression spring 502 downwardly pushes thesupport disk 503 such that thesupport disk 503 is urged closer to the connectingmember 504, while theblock 302 is pushed upwardly and drives thearms gripping sleeves right levers member 504 is caused to be urged upwardly which will drive thesupport disk 503 to likewise move upwardly to abut against thespring 502 on the one hand, while thearms block 302 and drive thestem 301 to move downwardly on the other hand. Pulling theadjustment nut 501 to move downwardly compresses thespring 502, and the upper and lower end of thespring 502 are compressed thus generating a torsional force. Such reciprocating bending action of the two hands in such a manner achieves the object of exercise. If the torsional force of the left and right hand levers 10,20 is to be adjusted, it is only necessary to tighten or loosen theadjustment nut 501 to adjust the degree of compression of thespring 502. When tightened, the spring is subjected to greater compression and the torsional force is greater; in contrast, when thespring 502 is loosened, the torsional force is smaller. To change the spring or replace the spring with one having a different compression force, all that is required is to remove theadjustment nut 501. It can thus be noted that the described embodiment of the present invention can achieve adjustment of the left and right hand levers 10,20 to different torsional force to fit users of different ages or of different strengths. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
