Combination exercise rack adjustment device

Abstract

A combination exercise rack adjustment device allows the combination exercise rack to have multiple positions for an upright. The positions translate to different angles that are used for specific exercises such as bench press and squats. The device has a cam with an extension that dictates the angle of the upright. In the preferred embodiment, a post is described that includes the adjustment device.

Claims

An adjustment device for an upright of a combination exercise rack, comprising: a cam; the cam having a first position and a second position; the cam configured to be mounted on a post of the combination exercise rack; a locking member to lock the cam in place; wherein the upright is configured to be inserted and hinged to the post to allow the upright to be positioned in at least two angles relative to the post depending on whether the cam is in the first position or the second position.

2. The adjustment device of claim 1, wherein: the cam has a first recess.

3. The adjustment device of claim 2, wherein: the cam has a second recess.

4. The adjustment device of claim 3, wherein: the cam has an extension member; the extension member is configured for the upright to rest on.

5. The adjustment device of claim 4, wherein: the locking member is threaded.

6. The adjustment device of claim 5, wherein: a retaining bar is configured to be selectively removable from the first recess.

7. A post for a combination exercise rack, comprising: a main body; the main body at least partially hollow; the main body configured to receive an upright; a cam; the cam having a first position and a second position; the cam configured to be selectively mounted on the main body; a locking member to lock the cam in place; wherein the upright is configured to be inserted and hinged to the main body to allow the upright to be positioned in at least two angles relative to the main body depending on whether the cam is in the first position or the second position.

8. The post of claim 7, wherein: the cam has a first recess.

9. The post of claim 8, wherein: the cam has a second recess.

10. The post of claim 9, wherein: the cam has an extension member; the extension member is configured for the upright to rest on.

11. The post of claim 10, wherein: the locking member is threaded.

12. The post of claim 11, wherein: a retaining bar is configured to be selectively removable from the first recess.

13. The post of claim 12, wherein: the post has a retaining member; the retaining member holds the retaining bar in place.

14. The post of claim 7, wherein: the post has a connecting member; the connecting member interacts with the locking member.

15. The post of claim 7, wherein: the post has an opening; the opening receives an extension member.

16. The post of claim 13, wherein: a second locking member is selectively connected to the retaining bar.

DETAILED DESCRIPTION

(10) Now referring to the drawings, FIGS. 1-9 show a combination exercise rack adjustment device 20. As best seen in FIGS. 2 and 3, the adjustment device 20 has a cam 30. The cam 30 has an extension member 32, a first recess 34 and a second recess 36. The cam also has an opening 38 which can accommodate a connecting member 52 of a post 50 configured to receive an upright 60.

(11) As seen in FIG. 4, a locking member 40 serves as a cover as well as maintaining the position of the cam 30. Preferably the locking member 40 is lock collar knob. The locking member 40 has an opening 42 that is preferably threaded to correspond to threads of the connecting member 52. The locking member 40 is then simply screwed onto the connecting member 52 until tightened.

(12) As best shown in FIGS. 6-8, the preferred embodiment of the post 50 includes the exercise rack adjustment device 20. The post 50 has the connecting member 52, a retaining member 54, an opening 56, and a main body 57 that is at least partially hollow to form a cavity 58. These elements of the post 50 interact with the cam 30 and locking member 40.

(13) In use, the cam 30 is placed such that the extension member 32 is within the opening 56 of the post 50 and that the connecting member 52 fits into the opening 38 of the cam 30. The cam 30 is then turned to the desired location which is having either the first recess 34 or second recess 36 under the retaining member 54 of the post 50. The first recess 34 correlates to a first position and the second recess correlates to the second position. The locking member 40 is then placed on the connecting member 52 and tightened to maintain the cam 30 in either the first position or second position.

(14) To further assist maintaining the selected position of the cam 30, a retaining bar 70 can be selectively inserted through the retaining member 54 as shown in FIGS. 7 and 8. Furthermore, a second locking member 71 is attachable to the retaining bar 70 to further secure the retaining bar 70 and thus the cam 30 in the selected position.

(15) Depending on the position selected, an upright 60 placed in the cavity 58 will have a different angle as shown in FIGS. 7 and 8.

(16) Having thus described the invention in connection with the preferred embodiments thereof, it will be evident to those skilled in the art that various revisions can be made to the preferred embodiments described herein with out departing from the spirit and scope of the invention. It is my intention, however, that all such revisions and modifications that are evident to those skilled in the art will be included with in the scope of the following claims.
