FIELD OF THE INVENTION
The embodiments of the present invention relate to an exercise device utilizing resistance bands and being attachable to a desk, table, countertop or similar article.
BACKGROUND
For those people working in offices or at desks, it can be challenging to find time to exercise. With the pandemic in full swing, the population of people sitting behind desks is ever increasing. Even a slight increase in heart rate can overcome the negative health consequences of a sedentary lifestyle.
It would be advantageous to develop an exercise device that may be attached to a desk, for example, and used while seated in the desk chair. Importantly, the exercise device, when not being used, should not interfere with use of the desk for conventional non-exercise activities.
SUMMARY
Accordingly, a first embodiment of the present invention comprises broadly a pair of brackets configured to attach to a desktop in a spaced manner, resistance bands configured to extend from a handle to said two spaced brackets wherein the handle is a near a mid-point thereof. When attached to the desktop, the brackets maintain the resistance bands and handle generally underneath the desktop when not in use. When needed, the user grips the handle with two hands and performs various exercises while seated in his or her chair.
In one embodiment, the brackets are configured to retain multiple resistance bands allowing the user to increase or decrease the resistance as needed. In another embodiment, the brackets are configured to provide increased stability against the force of the user pulling on the one or more resistance bands while exercising.
In another embodiment, one or more additional resistance bands and handles are removably attached to the brackets to provide unique exercise options over the resistance bands extending between the brackets.
Other variations, embodiments and features of the present invention will become evident from the following detailed description, drawings and claims.

DETAILED DESCRIPTION
For the purposes of promoting an understanding of the principles in accordance with the embodiments of the present invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive feature illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention claimed.
The brackets and handle of the present invention may be made using any suitable materials including, but not limited to, alloys, composites, metals, polymers, ceramics, plastics and combinations thereof. The resistance bands may be made using any suitable resilient materials including elastic, latex, rubber, fabric, etc. The components of the present invention may be fabricated using any suitable techniques including, but not limited to, milling, machining, molding, casting, 3D printing and combinations thereof.
FIGS. 1-4 show an exercise unit 100 attached to a desktop 105. While a desk is discussed herein, any piece of furniture or article with a generally flat top and bottom with an exposed edge and sufficient space underneath may receive the exercise unit 100. The exercise unit 100 comprises a pair of brackets 110-1, 110-2, a first set of resistance bands 120-1, 120-2, handle 130 and clips 140-1, 140-2. FIG. 2 shows a second pair of resistance bands 121-1, 121-2, corresponding handle 131 and clips 141-1, 141-2. As shown, the brackets 110-1, 110-2 are configured to maintain the first set of resistance bands 120-1, 120-2 and corresponding handle 130 beneath the desktop 105. The brackets 110-1, 110-2 are further configured to maintain the first set of resistance bands 120-1, 120-2 and corresponding handle 130 near the undersurface of the desktop so that the exercise unit 100 does not interfere with the user while he or she is seated in his or her chair while working at the desk.
FIGS. 5 and 6 show the exercise unit 100 not attached to a desktop. As shown in FIGS. 1-6, in one embodiment, the handle 130 is ergonomically designed to accommodate a user's hands. Angle A, defined by a left-hand grip 131-1 and right-hand grip 132-1, creates a V-shape generally matching an angle of a user's hands when using the exercise unit 100 in a seated posture. A straight handle would not perform well as the user's hands would tend to slip off and become fatigued quickly during use.
FIG. 6 shows the brackets 110-1, 110-2 configured so that the threaded connectors 117-1, 117-2 (e.g., threaded bolts) used to attach the exercise unit 100 to the desk are angled against the direction of force that is applied when a user pulls on the first set of resistance bands 120-1, 120-2. In this manner, the bolts 117-1, 117-2 tend to more securely maintain the exercise unit 100 in position when attached to the desktop.
FIG. 7 shows an exploded view of the exercise unit 100. Clips 140-1, 140-2 on the end of each resistance band 120-1, 120-2 serve to connect the first set of resistance bands 120-1, 120-2 to the brackets 110-1, 110-2 while second ends of the first set of resistance bands 120-1, 120-2 connect to the handle 130. As best seen in FIG. 8, the brackets 110-1, 110-2 include cut-outs 127-1, 127-2 for receiving clips 140-1, 140-2 of the first set of resistance bands 120-1, 120-2 and a second resistance band if desired. In an alternative arrangement, a single resistance band is used and extends completely through the handle 130. FIG. 12 shows a cut-away view of resistance band 120-1 connected to handle 130. A tube expansion plug 123 prevents resistance band 120-1 from dislodging from the handle 130 during use. In other words, the tube expansion plug 123 has a greater diameter than handle bore 133 so that the resistance band 120-2 remains connected to handle 130. A protective sleeve 134 or sheath prevents excessive wear and tear to the resistance band 120-1 that may be caused as the resistance band 120-1 stretches in the handle bore 133 during use. In one embodiment, the protective sleeve 134 is thermally attached to the resistance band 120-1.
FIG. 11 shows a second tube expansion plug 124 maintaining the resistance band 120-1 connected to clip 140-1. While tube expansion plugs are detailed herein, those skilled in the art will recognize that other fasteners and mechanisms may be used to connect the first set of resistance bands 120-1, 120-2 to the handle 130 and clips 140-1, 140-2.
Now referring to FIG. 12, the handle 130, in one embodiment, comprises two symmetric members 135-1, 135-2 joined over the first set of resistance bands 120-1, 120-2 and tube expansion plugs 123. The two handle members 135-1, 135-2 may be connected using mechanical fasteners 136, adhesives, etc. Alternatively, the handle 130 may be molded as a single piece over the resistance bands (or single resistance band as disclosed above). The handle 130 includes 8 finger grooves 137 to ergonomically accommodate a user's fingers while the thumbs are wrapped side-by-side under the handle 130.
FIGS. 8, 9A and 9B show views of a bracket 110-1 used to attach the exercise unit 100 to a desktop. When attached to a desktop, a flat (or horizontal) top member 111 sits on an upper surface of the desktop while vertical member 112 extends downward along a front edge of the desktop and first angled member 113 extends downward in a direction beneath the desktop and second angled member 114 extends upward at about 90° relative to the first angled member 113. The second angled member 114 includes a threaded aperture 116 for receipt of a threaded connector 117 permitting the bracket 110-1 to be attached securely to the desktop. The first angled member 113 includes cutouts 127-1, 127-2 for attachment of the first set of resistance bands 120-1, 120-2 via clips 140-1, 140-2. An underside of the top member 111 may include a cushion 119, pad or other protective item to prevent damage to an upper surface of the desktop.
Referring to FIG. 10, the brackets 110-1, 110-2 are designed such that the threaded connector 117, when tightened, contacts the undersurface of the desktop at an acute angle B increasing strength/stability against the force applied to brackets 110-1, 110-2 when the first set of resistance bands 120-1, 120-2 are pulled during use. This arrangement provides greater exercise unit 100 stability than if the threaded connectors 117 contacted the undersurface of the desktop at a substantially vertical or 90° angle.
In practice, a user seated at his or her desk may grip the handle 130 with two hands and pull the first set of resistance bands 120-1, 120-2 from side-to-side, upward and downward (crunches) or in any number of directions to work different muscle groups including the core while increasing heart rate. The exercise unit 100 offers both cardio and core strengthening simultaneously. Using different strength resistance bands and numbers thereof, a user can create a complete workout regime suitable for time at his or her desk.
FIG. 14A shows the exercise unit 100′ with a second set of resistance bands 205-1, 205-2 and corresponding handles 210-1, 210-2 attached to brackets 215-1, 215-2 via slots 220-1, 220-2 according to the embodiments of the present invention. FIG. 14B shows exercise unit 100′ with additional resistance band 205-2. FIG. 14C illustrates a close up of the second set of resistance bands 205-2, 205-3 and corresponding handles (not shown) attached to a single bracket 215-2 of the exercise unit 100′ according to the embodiments of the present invention.
FIG. 15A shows a user doing curling type exercises using the second set of resistance bands 205-1, 205-2 and handles 210-1, 210-2. FIG. 15B shows a user doing press type exercises using the second set of resistance bands 205-1, 205-2 and handles 210-1, 210-2. FIG. 15C shows a user doing upper back type exercises using the second set of resistance bands 205-1, 205-2 and handles 210-1, 210-2. FIG. 15D shows a user doing shoulder and triceps type exercises using the second set of resistance bands 205-1, 205-2 and handles 210-1, 210-2.
FIG. 16A shows an alternative bracket design 300 according to the embodiments of the present invention. In this embodiment, the bracket 300 includes a plurality of apertures 305-1 through 305-4 configured for attachment of resistance bands. Bracket 300 attaches to a table or desk in the same manner described relative to brackets 110-1, 110-2.
FIGS. 16B and 16C show the alternative bracket design 300 in practice according to the embodiments of the present invention. As shown, apertures 305-3 and 305-4 on bracket 300-1 and apertures 305-1 and 305-2 on bracket 300-2 are used to secure horizontal resistance bands 315-1 and 315-2, respectively. Apertures 305-1 and 305-2 on bracket 300-1 and apertures 305-3 and 305-4 on bracket 300-2 may be used to attach additional resistance bands as shown in FIGS. 14A-14C.
Besides increasing heart rate and exercise muscles, the exercise unit 100 helps people be more productive by keeping them awake and alert and providing more energy. By sitting up straight with shoulders back and strengthening the abdominal muscles, the exercise unit 100 also helps people with neck, shoulder and lower back pain. The exercise device 100 also helps people cope with depression or other negativity by offering short healthy bursts of exercise which has been shown to make people feel good about themselves.
Although the invention has been described in detail with reference to several embodiments, additional variations and modifications exist within the scope and spirit of the invention as described and defined herein.
