DETAILED DESCRIPTION

[0022] In the following detailed description, reference is made to the accompanying drawings and photographs that form a part hereof, and in which is shown by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and like numerals represent like details in the various figures. Also, it is to be understood that other embodiments may be utilized and that process or other changes may be made without departing from the scope of the disclosure. The following detailed description is not to be taken in a limiting sense, and the scope of the invention is defined only by the appended claims and their equivalents. In accordance with the disclosure, a weight lifting and/or functional fitness bar that utilizes an abrasive (sand) blasting finish is hereinafter described.

[0023] Reference is now made to FIGS. 1-4, which are various views illustrating a weight lifting or functional fitness bar 10 that may be utilized in commercial, cross-fit and home gyms. The weight lifting bar may be a variety of different bars, such as a pull-up bar, dead lift bars, Olympic bar, barbell or dumbbell. The weight lifting bar illustrated in FIGS. 1-3 is a pull-up bar 10 is typically made from a rigid material, such as bare or raw steel to withstand the rigors of repeated use by one or more individuals. It should be appreciated that the pull-up bar disclosed herein may be used on weight racks, rigs and wall mounts. As discussed in more detail below, an abrasive or sand blasted process finish is applied to the bar to provide a roughed surface on the raw steel surface. The roughed surface creates enhanced grip, which does not easily wear and retains a sticky grip for individuals to use the bar.

[0024] The pull-up bar 10 includes a cylindrical bar 20, which may be welded to a pair of opposed end pieces 30, 40. The cylindrical bar is typically made of steel. The end pieces 30, 40 include a flange 50, 60 projecting from the end piece and welded to the pull-up bar 10 for providing additional strength and reinforcement. The end pieces 30, 40 may be affixed to a wall (W), power rack or cage 80. Fasteners, such as bolts may be used to affix the end pieces 30, 40 to the wall, power rack or cage.

[0025] The pull-up bar 10 includes a sandblasted process finish 70 creating a second layer 100 over the base steel layer 90. The sand blasted finish provides enhanced grip properties and facilitates pivoting movement of the individual's hands during the transitional phase of pull-ups.

[0026] Sandblasting is a process of forcing solid particles across a hard surface at high speeds using compressed air in order to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.

[0027] In this case, sandblasting is used on the pull-up bar 10 to create a second layer 100, i.e., a rough surface to promote better grip for the individual using the bar. The second layer 100 may cover substantially an entirety of the first or base layer 90. Alternatively, the second layer 100 may cover over half the first or base layer 90. In yet another embodiment, the second layer 100 may cover about half the first or base layer 90. Importantly, the sand blasting process is a quick and efficient solution to improve the grip properties of the metal bar, without diminishing the appearance of the bar.

[0028] It should be appreciated that the sandblasting process may vary based on the type of medium used and the particulars about the media, i.e., type, shape, size, hardness and density as well as air velocity of the blasting process. For example, it is known to use silica sand or silicon dioxide, soda, steel grit, glass bead, plastic beads, garnet, aluminum oxide and others as the media. Other variables in the sandblasting process includes the type of nozzle used for the blasting and the pressure applied for the blasting process. The sandblasted process finish 90 does not easily wear out and retains a sticky/raised grip. The sand blasting process described herein utilizes glass beads to create a sticky mill or frosted finish to the bar. The blast process is known as bead blasting.

[0029] Typically, a traditional pull-up bar includes a grip that is merely clear or powder coated over bare steel, also known as black pipe, which does not have the grip properties of the sandblasted process finish described herein. Instead, conventional power-coated bars become slippery after repeated use and must be replaced.

[0030] Advantageously, the pull-up bar 10 with the sandblasted process finish may be used for multiple years without wearing down, i.e., it retains a good grip. Furthermore, the enhanced grip from the sandblasted process finish does not require the individual to use leather and/or cloth grip hand protection appliances on their hands during use of the bar. However, if an individual desires to use gloves, grip pads or chalk to enhance grip, the sandblasted process finish described herein may complement the use of the gloves, grip pads or chalk to improve the grip. The sandblasted process finish decreases the likelihood of an individual's hands and calluses tearing and/or bleeding, which is common with other traditional bars. Finally, it should be appreciated that the sandblasting finish may be used on other pieces of gym equipment, such as barbells and dumbbells.

[0031] The foregoing descriptions of various embodiments have been presented for purposes of illustration and description. These descriptions are not intended to be exhaustive or to limit the invention to the precise forms disclosed. The embodiments described provide the best illustration of the inventive principles and their practical applications to thereby enable one of ordinary skill in the art to utilize the disclosure in various embodiments and with various modifications as are suited to the particular use contemplated.
