Adjustable exercising device

[0001] 1. Field of the Invention

[0002] The present invention relates to exercising equipment and, more particularly, to an adjustable exercising device.

[0003] 2. Description of the Prior Art

[0004] As shown in FIG. 1, a conventional exercising device includes a cylinder-shaped spring 10 having two ends, each connecting with a shaft 20. The shaft 20 includes a handle 30 fitted to an outer side thereof. The handle 30 is held and compressed inward by a user to twist the spring 10. After releasing the exercising device, the spring 10 recovers its shape by using resilience, thereby exercising the user's arms and chest.

[0005] However, the conventional exercising device still has the following disadvantages:

[0006] 1. The exercising device is fixed and can not be adjusted by the user based on requirement, limiting its usage.

[0007] 2. While compressing the exercising device, each coil of the spring 10 will generate a gap to clamp the user dangerously.

[0008] 3. The exercising device is fixed and can not decrease its size, making storing inconvenient.

[0009] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

[0010] The primary object of the present invention is to provide an adjustable exercising device that is assembled and disassembled easily and quickly.

[0011] A further object of the present invention is to provide an adjustable exercising device that can prevent the resilient straps from injuring the user.

[0012] Another object of the present invention is to provide an adjustable exercising device in which the resilient straps and the grip members are allowed to be assembled and disassembled according to the required number and to decrease storage size.

[0013] An adjustable exercising device includes two grip members and three resilient straps. Each of the grip members includes a body, an engaging member, an elastic element, and a positioning cover. The body includes a lateral coupling seat having three inserting holes disposed on a front end thereof and a handle extending from a rear end thereof to connect with a hanging rope. The handle is filled with foam material. The coupling seat further has a sliding groove fixed on a side thereof, communicating with the inserting holes and being in response to a cross section of the engaging member to be formed in a projection shape. The coupling seat further has a retaining recess secured on an opening end of the sliding groove. The engaging member includes a pushing portion fixed on a top surface thereof, a notch arranged on an inner wall thereof, and three locking projections disposed on a bottom thereof. Each locking projection has a beveled surface mounted on a front end of one side thereof. The elastic element, such as a spring, is formed in a lamination shape. The resilient strap has a proper elasticity, and a connector is fixed on each of two ends thereof. The connector includes an engagement slot or engagement bore arranged on one side thereof.

[0023] The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustration only, the preferred embodiments in accordance with the present invention.

[0024] Referring to FIGS. 2-6, an adjustable exercising device comprises two grip members 1 and three resilient straps 2. Each of the grip members 1 includes a body 11, an engaging member 12, an elastic element 13, and a positioning cover 14. The body 11 includes a lateral coupling seat 111 having three inserting holes 112 disposed on a front end thereof and a handle 113 extending from a rear end thereof to connect with a hanging rope 114. The handle 113 is filled with foam material. The coupling seat 111 further has a sliding groove 115 fixed on a side thereof, communicating with the inserting holes 112 and being in response to a cross section of the engaging member 12 to be formed in a projection shape. The coupling seat 111 further has a retaining recess 116 secured on an opening end of the sliding groove 115. The engaging member 12 includes a pushing portion 121 fixed on a top surface thereof, a notch 122 arranged on an inner wall thereof and three locking projections 123 disposed on a bottom thereof. Each locking projection 123 has a beveled surface 1231 mounted on a front end of one side thereof. The elastic element 13, such as a spring, is formed in a lamination shape. The resilient strap 2 has a proper elasticity, and a connector 21 is fixed on each of two ends thereof. Each connector 21 includes an engagement slot 211 or engagement bore arranged on one side thereof.

[0025] In assembly, one end of the elastic element 13 is fitted into the notch 122 of the engaging member 12. Then, the elastic element 13 and the engaging member 12 are fitted to the sliding groove 115 of the body 11. The positioning cover 14 covers the retaining recess 116 of the body 11 to limit the engaging member 12 to not disengage from the sliding groove 115 of the body 11. The elastic element 13 is pressed to abut against an inner side of the notch 122 of the engaging member 12 by using its one end, and another end of the elastic element 13 is biased against an inner side of the sliding groove 115. Then, the connectors 21 of the two ends of the resilient strap 2 are inserted to the inserting holes 112 to push against the beveled surface 1231 of the locking projection 123 of the engaging member 12. The elastic element 13 is compressed to drive the engaging member 12 to slide horizontally. As the connectors 21 are inserted to predetermined positions, the engaging member 12 is pushed by the elastic element 13 to move back to its original position. The locking projection 123 is retained in the engagement slot 211 of the connector 21, finishing assembly.

[0026] In operation, the two grip members 1 are held by the user to be pressed inward to twist the resilient straps 2. After the user releases the resilient straps 2, the resilient straps 2 recover their resilience to exercise the user's arms and chest.

[0027] As shown in FIG. 7, when desiring to remove the resilient straps 2, the engaging member 12 is pushed away from the sliding groove 15 by pushing the pushing portion 121 so that the elastic element 13 compresses the locking projections 123 of the engaging member 12 to disengage from the engagement slots 211 of the connectors 21 of the resilient straps 2. Then, the connectors 21 of the resilient straps 2 are pulled away from the inserting holes 112 of the body 11.

[0028] Referring to FIGS. 8 and 9, one or two resilient straps 2 are selected to be inserted to the inserting holes 112 located on two outer sides of the coupling seats 111 or the inserting holes 112 located on a middle portion thereof.

[0029] It is apparent from the above description that the adjustable exercising device of the present invention has the following advantages:

[0030] 1. The number of the resilient straps 2 is selective based on requirement to assemble and disassemble from the predetermined inserting holes 112 easily, adjusting desired resiliently twisted resistance.

[0031] 2. In assembly, the resilient straps 2 are inserted to the inserting holes 112 directly. Also, by pushing the engaging member 12 outward, the resilient straps 2 are disassembled quickly.

[0032] 3. The resilient straps 2 are located between the handles 1, preventing the resilient straps 2 from injuring the user.

[0033] 4. The resilient straps 2 and the grip members 1 allow to be assembled and disassembled according to required number to decrease storage size.

[0034] While various embodiments have been shown and described in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
