Exerciser capable of doing multidirection actions
An exerciser includes a main body having two sets of locating holes symmetrically disposed at left and right sides along a respective smoothly arched track, two swivel connectors each having a fixed end pivoted to a center of figure of one smoothly arched track at the main body, and a retaining member engaged in one of the locating holes for locking the respective swivel connector to the main body, two handlebars having one ends respectively pivoted to the swivel connectors and the other ends provided with a grip respectively, and two elastomeric members respectively coupled between the swivel connectors and the handlebars.
1. Field of the Invention
The present invention relates to apparatus for physical exercises and, more particularly, to an exerciser capable of doing multi-direction actions, e.g. an operation angle-adjustable scissors-action exerciser.
2. Description of the Related Art
When in use, the user's back is supported on the soft front pad 111, and the user holds the handlebars 130 with the hands and moves the handlebars 130 inwards and outwards to perform a scissors action. When wishing to change the operation angle, the user must dismount the elastomeric members 131 and then loosen the lock screw 123 of each coupling device 120, for enabling the respective handlebar 130 to be turned to the desired angle. This design of scissors-action exerciser has a complicated structure formed of a big number of parts, leading to high manufacturing cost. Further, when wishing to change the operation angle of the handlebars, the adjustment procedure is complicated.
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide an operation angle-adjustable scissors-action exerciser, which has the advantages of simple structure, less number of parts, and low manufacturing cost.
It is another object of the present invention to provide an operation angle-adjustable scissors-action exerciser, which is easy to operate.
To achieve these objects of the present invention, the exerciser comprises a main body for the rest of the user's back, two swivel connectors, two handlebars, and elastomeric members. The main body has two sets of locating holes symmetrically disposed at left and right sides thereof along a respective smoothly arched track at the main body. The two swivel connectors each have a fixed end pivoted to a center of figure of one smoothly arched track at the main body, and a retaining member engaged in one of the locating holes for locking the respective swivel connector to the main body. The two handlebars each have a first end pivoted to the swivel connector and a second end provided with a grip. The elastomeric members are respectively symmetrically coupled between the swivel connectors and the handlebars.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
The main body 20 comprises a substantially flat rectangular open frame 21, and two semicircular coupling plates 22 symmetrically bilaterally disposed at the back side. The semicircular coupling plates 22 each have a serrated arc defining a plurality of positioning notches 23, and a smoothly arched sliding slot 24 extended corresponding to the serrated arc.
The back pad 25 is fixedly provided at the front side of the open frame 21 of the main body 20 for supporting the user's back.
As shown in
The two handlebars 40 (see
The two elastomeric members 50 are respectively molded from rubber, each having two end holes 51 and 52 disposed at two distal ends and respectively coupled to the hook rod 38 at one swivel connector 30 and the hook rod 42 at one handlebar 40.
The operation angle-adjustable scissors-action exerciser can be used in a universal gym. Alternatively, the operation angle-adjustable scissors-action exerciser can be provided with shoulder straps for fastening to the user's back. The operation of the operation angle-adjustable scissors-action exerciser is outlined hereinafter with reference to FIGS. 6˜8.
As illustrated in
As indicated above, the operation angle-adjustable scissors-action exerciser has the advantages of simple structure, less number of parts, and low manufacturing cost. Further, the user needs not to change the position of the two elastomeric members when adjusting the angular positions of the swivel connectors and the handlebars relative to the main body. Additional elastomeric members may be added to increase the damping resistance, enhancing the exercising strength.
The main body 70 comprises a substantially rectangular flat base 71. The rectangular flat base 71 has two sets of locating holes, for example, screw holes 72 symmetrically disposed near two opposite lateral sides and respectively arranged along a smoothly arched track.
The two swivel connectors 80 each comprise an elongated connector body 81, the elongated connector body 81 having an angled fixed end pivoted to the center of figure of the smoothly arched track along which one set of screw holes 72 is arranged and a free end provided with a through hole 82, and a retaining member, for example, a screw bolt 83 inserted through the through hole 82 and selectively threaded into one screw hole 72 (see
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
Claims
1. An exerciser comprising:
- a main body for the rest of a user's back, said main body having two sets of locating holes symmetrically disposed at left and right sides thereof along a respective smoothly arched track at said main body;
- two swivel connectors each having a fixed end pivoted to a center of figure of one smoothly arched track at said main body, and a retaining member engaged in one of said locating holes for locking the respective swivel connector to said main body;
- two handlebars each having a first end pivoted to one said swivel connector and a second end provided with a grip; and
- a plurality of elastomeric members respectively coupled between said swivel connectors and said handlebars.
2. The exerciser as claimed in claim 1, wherein the fixed end of each said swivel connector is angled and perpendicularly pivoted to said main body for enabling said handlebars to be turned about an axis perpendicular to the axis about which the corresponding swivel connector is turned.
