Patent Application
20180338584
The present invention relates generally to a body fitting device, and more particularly to a strap connector of a body fitting device.
The human population of the word is continuously increasing and this leads to an increasingly concentrated building arrangement in an urban area, while outdoor spaces are increasingly diminishing. Consequently, spaces for outdoor activity of people are reduced.
Gyms are now commonly established in metropolises and cities to provide indoor spaces for exercises for urban people. One of the most favorite exercise devices that are often available in the gyms is a tension device, which is structured for people to train their arm strength and chest muscles by using a strap connected between a grip and a weight, so that a user may hold the grip and pull the weight through the strap for exercising and training purposes.
To prevent an over-stiff connection for operation of a tension device, two straps are often used for connection, where a first one has an end coupled to the weight and an opposite end coupled to a connector and a second one has an end coupled to the grip and an opposite end coupled to the connector so that the connector functions as a connection interface between the two straps. In this way, the connector that has an adjustable space provides a flexible connection of the straps at the time when an initial pull is made. However, the adjustable or movable clearance provided in the connector makes the user feel sudden impact during pulling of the straps. This causes discomfort of the user and may also readily lead to undesired stretching of muscles of the user.
In view of the problems, to improve the prior art, where a strap connector of a known body fitting device may readily causes impact and may cause no-resistance pulling, leading to discomfort of operation and damage to human body, the present invention provides a strap connector of a body fitting device, which generally comprises: a connector body, which comprises a first movement space and a second movement space that is separated from the first movement space; a first movable block, which is slidably mounted to the connector body and is received in the first movement space and is reciprocally slidable upon being acted upon by an external force; a second movable block, which is slidably mounted to the connector body and is received in the second movement space and is reciprocally slidable upon being acted upon by an external force; and an elastic assembly, which is in contact engagement with and positioned between the connector body and the second movable block to provide an elastic cushioning force to the second movable block. As such, impact occurring during a sliding movement of the second movable block can be eliminated to provide a comfortable effect of pulling to a user and also to effectively protect the user from potential risk of damage caused by non-resistance pulling during a pulling operation.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

The above provides descriptions concerning structure and assembly of each of the components that make up the strap connector 100 of a body fitting device according to the first embodiment of the present invention. An operation of the invention will be described below:
To use the present invention, as shown in
When a user pulls the second strap 70, as shown in
Further, when the second movable block 30 is driven and moved by the second strap 70, as shown in
Further, in the above embodiment, the through holes 116 of the connector body 10 are each constructed to include a small bore or aperture 117 in communication with the second movement space 112 and a large bore or aperture 118 that is coaxially connected to the small aperture 117 and is in communication with the outside. The head portions 511 of the guide members 51 of the guide assembly 50 have an outside diameter that is less than a bore diameter of the large apertures 118 of the connector body 10 and greater than a bore diameter of the small aperture 117, while the shank portions 512 have an outside diameter that is less than the bore diameter of the small apertures 117 of the connector body 10. In this way, the small apertures 117 are sized to allow the shank portions 512 to respectively extend therethrough and the large apertures 118 are sized to hold and keep the head portions 511 therein (as shown in
Further, in the above embodiment, the springs 41 of the elastic assembly 40 are set in contact engagement with the engaging sections 123 of the regulators 12 of the connector body 10 so that a user may use a tool (such as hexagonal spanner) to engage and rotate the driving sections 122 to adjust positions of the regulators 12 for applying different forces acting on the springs 41 to thereby achieve an effect of adjusting and regulating the pre-loaded elastic force of the springs 41.

In the instant embodiment, the connector body 80 comprises a connector base 81 and three regulators 82. The connector base 81 comprises a first base 817, a second base 818, and a coupling strap 819. The first base 817 is in the form of a rectangular frame and comprises a first movement space 811 formed in an interior thereof. The first movement space 811 has two opposite inside surfaces each of which is provided with a first movement rail 813. The second base 818 is in the form of a rectangular frame and comprises a second movement space 812. The second movement space 812 has two opposite inside surfaces each of which is provided with a second movement rail 814. The second base 818 has an end wall that comprises three threaded holes 815 and two through holes 816, which are each located between two adjacent one of the threaded holes 815, formed therein to extend from an outside surface thereof to the second movement space 812. The coupling strap 819 is connected between the first base 817 and the second base 818. The remaining parts and assembly are similar to those of the first embodiment and repeated description will be omitted herein.
As such, to use the instant embodiment, as shown in
When a user pulls the second strap 70, in a way similar to the previous embodiment, the elastic forces generated by the elastic assembly 40 provide a cushioning force for an impact caused by the operation to prevent a shocking impact from occurring on the second movable block 30 during the sliding movement. In this way, the user is provided a better effect of exercise through pulling and is also protected against any potential risk of damage caused by momentary no-resistance sliding.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
