Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention is a continuous loop exercise apparatus designed so as to enable users thereof to exercise multiple body parts through resistive training.

Brief Description of the Prior Art

With the advancement of modern technological gadgets, the increasing dependency of humans on these technological gadgets and services received by them is causing adverse impact on certain aspects of human lifestyle such as physical activity. Physical training such as resistive training and cardiovascular training is required for overall physical fitness. In the current scenario, considering the paucity of time and space constraint, it is difficult to visit or maintain a gym at home. Therefore, there is a need for devices that are compact, portable, easy to assemble and disassemble while allowing the flexibility to execute various types of exercises.

Various exercise devices formed from rods and bars are available which could be portable but lack the flexibility in use. The device disclosed in U.S. Pat. No. 5,399,138, for example, is an abduction exercise device which includes a helical spring serving as a pivot to permit the arms to move away from each other and is also configured to grip the legs of the human when being used to exercise the legs. The devices disclosed in US Design patent No. D343,882 and US Design patent No. D322,827 is an ornamental design of exerciser that include a spring means.

The device disclosed in U.S. Pat. No. 8,790,227 is an exercise apparatus that includes a U-bar, the ends of which are pivotally coupled to two Lbars by rotatable hinge assemblies containing a torsion spring. The device disclosed in U.S. Pat. No. 6,966,871 is an exercise device wherein the frame includes a pair of movable locks and the locks can be released and engaged by articulating the lock tab. A pair of springs are included in the structure of the bar and the bar post does not extend through the spring thus holding in the locked position.

Other prior art of note include U.S. Pat. No. 2,223,309 ('309 Patent), issued to Swanson; U.S. Pat. No. 3,640,529 ('529 Patent), issued to Kane; U.S. Pat. No. 3,985,354 ('354 Patent) issued to Schulkin; U.S. Pat. No. 6,120,424 ('424 Patent) issued to Arline; U.S. Pat. No. 6,616,580 ('580 Patent), issued to Chen; and US Patent Application Publication No. 2004/0110610 ('610 Publication) authored by Chen et al. The '580 Patent, in particular, describes a collapsible combination waist and leg exerciser comprising a base, two elastic frames, and two connected handles.

In use, the user may stand on base with hands grasped on the handles and bend waist forward facing elastic frames in order to exercise up and down repeatedly. The user may also sit on a chair with the chair's legs pressed on base by the weight of the user. The user's feet are urged against the top of handles for exercising up and down repeatedly. The user may lay back with feet urged against the top of handles in a continuous up and down movement. This can train or develop the parts of body such as chest, arms, waist, legs, and buttock effectively in a small environment.

The exercise devices disclosed in the prior-art have employed the use of both in-line coil spring and torsion springs thus providing either only a pivotal movement or as a fixed construction. Also, they can be used only for certain specified exercises. Some of the prior-art devices include the use of heavy components such weight plates, which are heavy to move.

To overcome the aforementioned disadvantages, the present invention incorporates a series of inline resistance elements and rigid intervening structures assembled so as to form a continuous loop of elements. This enables flexion or extension of the apparatus for imparting resistive training to different body parts of the user. Given the unique continuously looped design of the present invention, the exercise apparatus may be utilized in combination with the floor, on the chair, or can be placed on a table or countertop without the requirement to reconfigure or reassemble the product.

OBJECTS OF THE INVENTION

The principle object of the present invention is to provide a versatile, multipurpose and portable continuous loop exercise apparatus.

Another object of the invention is to provide a continuous loop exercise apparatus for the purpose of imparting resistive training.

Still another object of the invention is to provide a versatile, multi-purpose and portable continuous loop exercise apparatus which can be used for exercising on the floor, on the chair, or can be placed on a table or countertop as well, without the requirement of reconfiguring or reassembling.

A further object of the invention is to provide a versatile, multi-purpose and portable continuous loop exercise apparatus wherein, the low impact design of the apparatus minimizes wear on joints.

SUMMARY OF THE INVENTION

The present invention generally concerns a continuous loop exercise apparatus designed so as to enable users thereof to exercise multiple body parts through resistive training. The present invention incorporates a series of inline resistance elements and rigid intervening structures assembled so as to form a continuous loop of elements. The series of inline resistance elements are particularly located so as to enable flexion or extension of the apparatus for imparting resistive training to differing body parts of the user. The unique continuously looped design of the present invention is such that the exercise apparatus may be utilized in combination with floor, on the chair, or can be placed on a table or countertop as support structures without the requirement to reconfigure or reassemble the apparatus.

The continuous loop design provides extension type resistance elements that are in-line with rigid body members thereby eliminating elements that protrude from the compact dynamic volumetric space. Various aspects of the apparatus and its looped characteristics allow the exercise apparatus to be used for a wide variety of exercises and the one-piece curved design allows users with different body builds to perform the same exercises appropriately by changing the user-to-apparatus contact positions rather than by adjusting the dimensions of the equipment, as is the case with most of the prior-art exercise apparatus. When higher or lower resistance is desired, it is contemplated that the resistance elements may be readily swapped out for resistance elements of differing restorative force, but remain in-line with the rigid body members.

The simple assembling process enables the continuous loop exercise apparatus 10 to be quickly installed and carry out exercises to tone, tighten and strengthen the entire body.

The assembling of the continuous loop exercise apparatus 10 will be disclosed in detail. As shown in FIG. 2, firstly, the lower member 3 is placed on the floor. One of the resistance elements 5 with a first end 5a is placed over a first end of the lower member 3a. Similarly, another resistance element 5 with a first end 5a is placed over a second end of the lower member 3b. Further, the left member 4 with a left member 4a is placed over the second end 5b of the said resistance element 5. Similarly, the right member 2 with a right member 2a is placed over the second end 5b of the said resistance element 5. The apparatus is positioned to rest the right member 2 and the left member 4 on the floor.

Further, another resistance element 5 with a first end 5a is placed over a first end of the upper member 1a and yet another resistance element 5 with a first end 5a is placed over the second end of the upper member 1b. The assembled component 1 along with the two resistance elements 5 with their second ends 5b, are placed over a second end of the right member 2b and a second end of the left member 4b respectively. The continuous loop exercise apparatus 10 is then brought back to the original position with the lower member 3 resting on the floor. Various assembly methods are known and can be used for assembling the present invention without limitation to the assembling approaches discussed here.

Further details of assembling the continuous loop exercise apparatus 10 is as shown in FIG. 3a, FIG. 3b, and FIG. 3c, wherein the upper member 1 includes a first male spring-loaded connection 1c on the first end 1a and a second male spring-loaded connection 1c on the second end 1b. The right member 2 includes a first male spring-loaded connection 2c on the first end 2a and a second male spring-loaded connection 2c on the second end 2b. The lower member 3 includes a first male spring-loaded connection 3c on the first end 3a and a second male spring-loaded connection 3c on the second end 3b.
