The present disclosure relates generally to improved designs for an adjustable trap bar used for weightlifting exercises.
Weightlifting is a significant part of many exercise regimens. Using barbells, dumb-bells and the like provide the foundation of resistance based training that increases user strength. Traditional barbell design involves a straight piece with weights secured to either side thereto. The user lifts the weights via the center part of the straight piece.
Introduced in the 1980s, the trap bar is a device that replaces the center part of the straight piece between the secured weights found in a traditional barbell with a generally closed piece, which may be, for example, diamond, hexagonal or rectangular in shape. The weightlifter places himself or herself in the middle of the closed piece and lifts the secured weights using handlebars that are attached to each side of the closed piece.
Early trap bar embodiments are disclosed in U.S. Design Pat. Nos. 317,641 and 320,249, both invented by Al P. Gerard.
The advantages of a trap bar over a barbell for deadlift weightlifting include:
A) it may be easier to learn than the barbell deadlift.
B) there may be no hyperextension at lockout.
C) there may be no need for a mixed grip.
D) the high handles are useful for people with insufficient hip range of motion.
E) there may be less chance of getting pulled forward/spinal flexion.
F) the trap bar may still be just as hip-dominant as a barbell deadlift.
G) there may be better skill transfer to other sports.
The present invention is directed to a number of improved closed-piece and open-piece trap bar embodiments having adjustable properties that enable the user to have a safer and more effective weightlifting experience.
The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views, together with the detailed description below, are incorporated in and form part of the specification, and serve to further illustrate embodiments of concepts that include the claimed invention, and explain various principles and advantages of those embodiments.
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present invention.
The apparatus and method components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.

The front of the trap bar includes two front sleeve pieces 240a, 242a that are partially or fully hollow and built to encompass and slide along a front expansion piece 245a. The right side of the right front sleeve piece 242a is fused to the front side of the right side piece 230b. The left side of the left front sleeve piece 240a is fused to the front side of the left side piece 230a. In an alternative embodiment, the left side of the right front sleeve piece 242a is also fused to the right of the front expansion piece 245a. In an alternative embodiment, the right side of the left front sleeve piece 240a is also fused to the left of the front expansion piece 245a.
The back of the trap bar includes two back sleeve pieces 240b, 242b that are partially or fully hollow and built to encompass and slide along a back expansion piece 245b. The right side of the right back sleeve piece 242b is fused to the back side of the right side piece 230b. The left side of the left back sleeve piece 240b is fused to the back side of the left side piece 230a. In an alternative embodiment, the left side of the right back sleeve piece 242b is also fused to the right of the back expansion piece 245b. In an alternative embodiment, the right side of the left back sleeve piece 240b is also fused to the left of the back expansion piece 245b.
The front expansion piece 245a may include a plurality of locking holes 275a where the front expansion piece can be secured using one or more of locking mechanisms 250, 255. The locking mechanisms 250, 255 work in tandem with retaining slots 290a, 290b and stopper bolts 292a, 292b serve to control the expansion of the telescoping tubes to prevent them from coming apart. Alternatively, securing mechanisms (not shown) may be threaded through sleeve piece cutouts 240b, 242b to secure the back expansion piece 245b. In the alternative, threading may be used to secure the back expansion piece 245b.
The construction of the trap bar allows the user to adjust the trap bar by making it wider or narrower depending on user preference. In order to accomplish this, the user unlocks one or more of the locking mechanisms 250, 255. This allows the trap bar to increase or decrease in width depending on the preference of the user. Once the width of the trap bar is set to the user's preference, the user then locks one or more of the locking mechanisms 250, 255 to secure that width during use.
The user then loads and secures weights (not shown) on the weight-loading bars 210a, 210b. The user then steps within the trap bar and uses the handles 220a, 220b to lift and lower the trap bar.

The front of the trap bar includes a front set of two sleeve pieces 520a, 522a that are partially or fully hollow and built to encompass and slide along a front expansion piece (not shown) via a front cutout 521a. A pin 515c is positioned to the left of the front cutout 521a. A retaining slot 515a and a stopper bolt 525a prevent movement of the two sleeve pieces 520a, 522a when locked and allows movement of the two sleeve pieces 520a, 522a when unlocked.
The front of the trap bar includes a back set of two sleeve pieces 520b, 522b that are partially or fully hollow and built to encompass and slide along a front expansion piece (not shown) via a back cutout 521b. A retaining slot 515b and an optional stopper bolt 525b prevent movement of the two sleeve pieces 520b, 522b when locked and allows movement of the two sleeve pieces 520b, 522b when unlocked.
The back of the trap bar contains no connections.
The construction of the trap bar allows the user to adjust the trap bar by making it wider or narrower depending on user preference. In order to accomplish this, the user unlocks one or more of the locking mechanisms 515c. This allows the trap bar to increase or decrease in width via movement of the sleeve pieces 520a, 522a, 520b, 522b depending on the preference of the user. Once the width of the trap bar is set to the user's preference, the user then locks one or more of the locking mechanisms 515c to secure that width during use. The user then loads and secures weights (not shown) on the weight-loading bars 505a, 505b. (The user may use the option of the bent-leg or securing member feature of the open-piece trap bar described below to load the weights in a safer manner.) The user then steps within the trap bar and uses the handles 508a, 508b to lift and lower the trap bar.
Optionally, the nature of the shape of the left side piece and a right side piece 504a, 504b have a unique property that allows for easier and safer loading and unloading of weights on the weight-loading bars 505a, 505b. This is because the back end of the left side piece 504a has a left bent leg 507a and the back end of the right side piece 504b has a right bent leg 507b.
In
Set forth below are three other embodiments of open-piece trap bars having bent legs at the back end of the left side piece and the right side piece. These embodiments have the benefits of easy loading and unloading as described above in
