Description

PCT APPLICATIONDEADLIFT WEIGHT MACHINETECHNICAL FIELD

[0001] This invention relates to weight machines, in particular, weight machines to perform or simulate deadlifts.BACKGROUND

[0002] The deadlift is a common weightlifting exercise and a competitive sport in which a barbell is loaded with weights, and placed in front of the weightlifter. The weightlifter then squats or bends forward to grab the barbell, and using his or her legs, back, butt, and arms, hoists the barbell upward. In doing so, there is a risk that the barbell can hit the leg of the weightlifter. In deadlifting, the weight being lifted is generally well over hundreds of pounds, and for world class weight lifters, up to one thousand pounds or more. As such, having the barbell hit one’s legs on the way up with such extreme weights can be extremely dangerous. Therefore, there is a need for a deadlift weight machine that allows weightlifters to practice the deadlift exercise without the risk of having the barbell hit one’s legs.SUMMARY

[0003] The present invention is directed to deadlift weight machine that simulates the deadlift movement, but eliminates the interference typically created by the traditional Olympic-style weight bar by utilizing a split weight bar in which a first weight bar is operatively connected to a first weight stack, and a second weight bar is operatively connected to a second weight stack so that during the deadlift exercise, no portion of the weight bar is directly in front of the user’s legs.This configuration with a split weight bar also allows the user to modify the range of motion or travel during the deadlift movement to compensate for injuries or to challenge the competitive lifter.

[0004] For added versatility, each weight bar is independently adjustable from the other weight bar in a horizontal direction to adjust the distance between the first weight bar and the second weight bar, and a vertical direction to adjust the height of the weight bar. Adjustable handles can also be operatively connected to each weight bar to allow the lifter to adjust his or her hand grip position.BRIEF DESCRIPTION OF DRAWINGS

[0009] The detailed description set forth below in connection with the appended drawings is intended as a description of presently-preferred embodiments of the invention and is not intended to represent the only forms in which the present invention may be constructed or utilized. The description sets forth the functions and the sequence of steps for constructing and operating the invention in connection with the illustrated embodiments. It is to be understood, however, that the same or equivalent functions and sequences may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention. As such, features shown in one embodiment, but not another should not be taken to mean such features is exclusiveto the embodiment shown. Rather, features shown in one embodiment can be applicable to the other embodiment.

[0010] For purposes of this application, directional terms, such as vertical, horizontal, lateral, medial, up, down, left, right, front, back, and the like are not meant to be limiting, but rather, used for ease in description. As such, if an imaginary axis were drawn, the X-direction would be the lateral direction (left to right in FIG. 2), the Y -direction would be the forward-backward direction (left to right in FIG. 3), and the Z-direction would be the vertical direction (up and down in FIGS.2 and 3). In addition, rotational terms, such as yaw, pitch, and roll are also based on this x-y-z designation. As such, yaw refers to rotational direction about a Z-axis. Pitch refers to rotational direction about an X-axis. Roll refers to the rotational direction about a Y-axis.

[0011] Referring to FIGS. 1-4, the weight machine 100 of the present invention comprises a first weight bar 102a and a second weight bar 102b bilaterally arranged about a centerline C. The first and second weight bars 102a, 102b can be operatively connected to a weight stack 104. In some embodiments, the first and second weight bars 102a, 102b can be connected to their own respective weight stack 104a, 104b (FIGS. 1 -3). As such, the first weight bar 102a and first weight stack 104a, can be separate and independent from the second weight bar 102b and the second weight stack 104b. In some embodiments, the first and second weight bars 102a, 102b can be connected to the same weight stack 104 (FIG. 4).

[0012] The following describes one side of the weight machine 100; however, it is to be understood that the description also applies to the opposite side. Therefore, for each first component described, there can be an analogous second component bilaterally arranged on the opposite side as shown in the drawings.

[0013] The first weight bar 102a can be operatively connected to the first weight stack 104a via a first pulley system 106a. The first weight bar 102a, the first weight stack 104a, and the first pulley system 106a can be mounted to, or otherwise, operatively connected to a first frame 108a to provide structural integrity to the weight machine 100 and allow lifting of the first weight bar 102a to cause the first weight stack 104a to rise via the first pulley system 106a.

[0014] The first pulley system 106a can be comprised of one or more pulley wheels 110a and a first line 112a. The first line 1 12a can be any belt, cable, rope, chain, and the like, adapted for transferring force from an input (e.g. first weight bar 102a) to an output to move the weights 114a in the first weight stack 104a. The pulley wheels 110a can be connected to the first frame 108a in a fixed manner or in an adjustable manner. A first end 113 of the first line 112a can be operatively connected to the first weight bar 102a, then wraps around the one or more pulleys 110a and connects to the first weight stack 104a at an opposite end 115 so that movement of the first weight bar 102a results in movement of the weights 114a in the first weight stack 104a typical of traditional weight machines.

[0015] In the preferred embodiment, the first weight bar 102a is adjustable. Preferably, the first weight bar 102a is adjustable in a horizontal direction (latero -medial direction along the X- axis) and a vertical direction (up and down along the Z-axis). The weight bar 102a is generally an elongated bar 120a having a lateral end 122 and a medial end 124 positioned closer to the centerline C relative to the lateral end 122. The elongated bar 120a can be inserted into a mount 130. The mount 130 can be a bracket, a sleeve, or any other sturdy structure that can hold the elongated bar 120a and allow the elongated bar 120a to move vertically and laterally. For example, in the preferred embodiment, the mount 130 comprises a horizontal mount 132a and a vertical mount 134a. The horizontal mount 132a and the vertical mount 134a can be in the form of a rigid sleeve.Therefore, the horizontal mount 132a and vertical mount 134a can be hollow, each defining an opening that extends the entire length of the rigid sleeve. Although the cross-sectional shape of the sleeves can be any shape, the preferred cross-sectional shape is rectangular or circular. More preferably, the horizontal mount 132a and the vertical mount 134a are elongated box shapes with square-shaped cross-sections.

[0016] Preferably, the horizontal mount 132a and the vertical mount 134a are attached to each other in a perpendicular manner. As such, when the mount 130 is properly installed as part of the weight machine 100, the horizontal mount 132a is parallel to the surface of the floor (in the X- direction) while the vertical mount 134a is perpendicular to the surface of the floor (in the Z- direction).

[0017] To accommodate lateral movement of the weight bar 102a, the cross-sectional shape and dimensions of the horizontal mount 132a can be substantially similar to the cross sectional shape and dimensions of the elongated bar 120a, such that the elongated bar 120a can be inserted into the opening of the horizontal mount 132a. A sufficient gap can exist between the inner wall defining the opening of the horizontal mount 132a and the outer wall of the elongated bar 120a such that the elongated bar 120aa is able to slide in and out of the horizontal mount 132a. The horizontal mount 132a can further comprise a bar lock 136a to lock the elongated bar 120a in place at a desired location.

[0018] A variety of known locks can be employed. In the preferred embodiment, the bar lock 136a can have a lever 138 that can be rotated to create resistance against the elongated bar 120a to prevent the elongated bar 120a from sliding within the horizontal mount 132a. As such, a user is able to loosen the lever 138, slide the weight bar 102a to the desired location, then rotate the lever 138 to tighten the bar lock 136a against the weight bar 102a holding the weight bar 102a in placein the lateral direction. In some embodiments, the bar lock 136a can be a spring-loaded pin and the elongated bar 120a can have a plurality of holes 137 aligned along the length of the elongated bar 120a. The spring-loaded pin can be configured to insert into one of the plurality of holes 137 to lock the elongated bar 120a in place.

[0019] The vertical mount 134a can be configured to move the weight bar 102a in a vertical direction (Z-direction). For example, the weight machine 100 can further comprise an adjustment bar 140a attached to the frame 108a. The vertical mount 134a can be slidably mounted on to the adjustment bar 140. For example, the shape and dimension of the opening defined by the inner wall of the vertical mount 134a can be substantially the same as the shape and dimension of the outer wall of the adjustment bar 140a. As such, the user can raise or lower the vertical mount 134a relative to the adjustment bar 140a to change the resting height of the vertical mount 134a. Because the vertical mount 134a is fixed to the horizontal mount 132a, and the horizontal mount 132a houses the weight bar 102a, adjusting the height of the vertical mount 132 adjusts the height of the weight bar 102a.

[0020] A mount lock 142a can be used to fix the height of the vertical mount 134a in place. Any known locking mechanism can be used to lock the height of the vertical mount 134a. Preferably, the mount lock 142a is a pin, and the adjustment bar 140a comprises a plurality of holes 144 configured to receive the pin. The pin may be spring-loaded to be biased towards the adjustment bar 140a. As such, when the pin is vertically aligned with one of the holes 144, the pin has a tendency to enter into the hole 144. Once the pin enters a hole 144, the vertical mount 134a is unable to move relative to the adjustment bar 140. Although the pin-style lock can be sufficient to lock the vertical mount 134 in place relative to the adjustment bar 140, a secondary mount lock 146a can further be used. The secondary mount lock 146a can be similar to, and use the sameresistance style locking mechanism as the bar lock 136a. As such, the secondary mount lock 146a can have a lever of which rotation in a first direction locks the secondary mount lock 146a through increased resistance against the adjustment bar 140a, and rotation in an opposite direction unlocks the secondary mount lock 146a from the adjustment bar 140a. Other known methods can be used to lock the vertical mount 134a in place.

[0021] The adjustment bar 140 can be connected to the frame 108a through a primary rail 150a. The primary rail 150a can be fixed to the frame 108a in an immovable manner, while the adjustment bar 140a can be slidably mounted on the primary rail 150a. As such, with the mount 130 locked in place on the adjustment bar 140a, lifting of the weight bar 102a raises the mount 130, which raises the adjustment bar 140a, causing the adjustment bar 140a to slide up along the primary rail 150a in a vertical direction because the primary rail 150a is immovably fixed to the frame 108a. By way of example only, the adjustment bar 140a can comprise a first slidable collar 152a fixed at a top end 154 of the adjustment bar 140a, and a second slidable collar 156a fixed at a bottom end 158 of the adjustment bar 140a. Preferably, the first slidable collar 152a and the second slidable collar 156a are co-axially aligned. The first and second slidable collars 152a, 156a can be slidably mounted on the primary rail 150a to allow the adjustment bar 140a to move up and down adjacent to, and along, the primary rail 150a. Due to the slidable collars 152a, 156a at the top and bottom ends 154, 158 of the adjustment bar 140a, the adjustment bar 140a is stabilized within the Z-direction and moves in a vertical direction without swaying in a horizontal direction (X or Y-direction).

[0022] Nonetheless, due to the extreme force that can be placed on the primary rail 150a with heavy weights, the weight machine 100 can further comprise an auxiliary rail 160a. The auxiliary rail 160a can be fixed to the frame 108a in an immovable manner like the primary rail 150a andconfigured to allow the first adjustment bar 140a to slide along the auxiliary rail 160a. For example a third slidable collar 162a can be attached to the mount 130 or the adjustment bar 140a by a mounting rod 163. The third slidable collar 162a can be slidably mounted on the auxiliary rail 160a. Therefore, as the weight bar 102a is moved up and down, the mount 130 rises up and down with the weight bar 102a causing the adjustment bar 140a to rise up and down parallel to the primary rail 150a due to the first and second collars 152a, 156a, while the third collar 162a rises up and down along the auxiliary rail 160a, which is also parallel to the primary rail 150a. Therefore, the collars 152a, 156a, 162a working in conjunction with the primary rail 150a and auxiliary rail 160a keep the weight bar 102a moving smoothly in a vertical direction without swaying horizontally.

[0023] Due to the heavy weights being lifted and dropped repeatedly, the weight machine 100 can further comprise a dampening pad 170a to absorb the forces of the weight bar 102a being dropped. For example, the dampening pad 170a can be placed underneath any moving structure associated with the weight bar 102a so that when the weight bar 102a is at rest, the weight bar 102a directly or indirectly rests on the dampening pad 170a. By way of example only, the dampening pad 170 can be placed directly underneath any one or more of the adjustment bar 140a, the mount 130, the second collar 156a, and / or the third collar 162a. Therefore, when the adjustment bar 140a is at its lowest position, the adjustment bar 140a, the mount 130, the second collar 156, and / or the third collar 162 can rest on aa dampening pad 170a. If the user lifts the weight bar 102a, then drops the weight bar 102a, the adjustment bar 140a rises and drops accordingly and lands on the dampening pad 170a to protect the floor. As such, the dampening pad 170a can be a resilient member made of rubber, plastic, cork, or any other material that can absorb the forces of the weights being dropped.

[0024] To facilitate lifting of the weights, the weight bar 102a can further comprise a handle 180a. Preferably, the handle 180a comprises a first grip bar 181a in the form of a cylindrical bar, a first mounting frame 183a fixed to the first grip bar 181 a to position the first grip bar 181a parallel to the first elongated bar 120a, and a first rod 182a fixed to the first mounting frame 183a in a perpendicular direction relative to the first grip bar 181a, wherein the first handle 180a is configured to rotate relative to the first weight bar 102a about a longitudinal axis A defined by the first rod 182a.

[0025] As such, the handle 180a is adjustable so that the user can employ different grip styles. Preferably, the handle 180a can be rotatable about the Z-axis (yaw rotation) so that the user can employ a palm forward grip, a palm towards the side grip (or toward each other), or a palm backward grip, or any angle therebetween. As such, the handle 180a can be mounted on the weight bar 102a about a vertical axis A (parallel to the primary rail 150a) to allow the handle 180a to rotate about the vertical axis A (yaw rotation). In some embodiments, the handle 180a can rotate a full 360 degrees. In some embodiments, the handle 180a can rotate within approximately a 90 degree range. In some embodiments, the handle 180a can be configured to rotate continuously within the desired range. In some embodiments, the handle 180a can rotate within fixed increments. For example, when the handle 180a is parallel to the weight bar 102a, this may be considered a zero degree rotation. With the handle 180a at zero degrees, the user can employ a palm forward or palm backward grip. The handle 180a can then be rotated so as to be about 90 degrees relative to the weight bar 102a. In this configuration, the user can use a grip in which the palms face inward or toward each other.

[0026] To facilitate the ease of rotating the handle 180a, the handle 180a can be spring loaded to be biased upwards away from the first weight bar 102a in a locked configuration, such thatcompression or downward pressure on the handle 180a towards the first weight bar 102a releases the handle 180a to an unlocked configuration, allowing the handle 180a to be rotated to a desired yaw position; and when downward pressure is released, the handle 180a springs upward into the locked configuration. For example, the handle 180a may be mounted on a rod 182a. The rod 182a can be placed in a housing 184a at the medial end 124 of the weight bar 102a, such that the rod 182a can rotate about the vertical axis A. A pin 186 can project radially outwardly from the rod 182a perpendicular to the vertical axis A up to or beyond the diameter of the housing 184a. The bottom of the housing 184a can be configured with a plurality of diametrically opposing grooves 188 to receive or seat opposite ends of the pin 186. The grooves 188 are positioned around the perimeter of the housing 184 to set the degree of rotation of the handle 180. Therefore, at rest, the pin 186 resides in one set of diametrically opposite grooves 188. Because the handle 180a is biased upwardly and fixed to the pin 186 via the rod 182a, the pin 186 remains inside the groove 188, and the handle 180a cannot rotate. To rotate the handle 180a, the user can press down on the handle 180a, which causes the pin 186 to move outside the groove 188 allowing the handle 180a to rotate. The handle 180a can be rotated to the next desired position, and when the pressure on the handle 180a is released, the pin 186 falls into the closest groove 188 causing the handle 180a to be fixed at the new angle. Thus, grooves 188 may be positioned to allow the handle 180a to be locked at zero degrees relative to the weight bar 102a, 30 degrees, 45 degrees, 60 degrees, 90 degrees or any angle therebetween. In some embodiments, the handle 180a can have a free rotation mode so that while the weight bar 102a is bearing a load, the user can rotate the handles 180 freely to exercise the forearms. Other types of locks such as the first bar lock 136a and the secondary mount lock 146a can also be used to lock the handle 180a in a desired orientation.

[0027] In some embodiments, the first handle 180a can be configured to tilt about 91 degrees to about 110 degrees in a medio-lateral direction (moved along the X-axis and rotated about the Y-axis) when rotated to be perpendicular to the first weight bar 102a. For example, the handle 180a. When the handle 180 is in the 90 degree configuration, the plane of the handle 180 can be perpendicular to the length of the weight bar 102a. FIG. 4 shows the handle 180 in a 0 degree configuration with the plane of the handle 180 parallel to the weight bar 102a. In some embodiments, with the handle 180 in the 90 degree configuration (see, FIGS. 1-2), the handle 180 can be tilted in the medio-lateral direction (along the X-axis) in which the plane of the handle 180a forms a tilt angle T with the weight bar 102a. Preferably the tilt angle T can range from about 91 degrees to about 100 degrees. More preferably, the tilt angle T is about 97 degrees. The tilt angle T can be fixed, or it can be adjustable.

[0028] The weight stack 104a can be a typical weight stack used in typical weight machines, and includes other forms of weight resistance, for example, using hydraulics, elastic bands, cam arms as used in plate-loaded equipment, and the like. In the preferred embodiment, the frame 108a can comprise a weight rack 190 to hold change plates 191 (or fractional weights). In the preferred embodiment, the weight rack 190 can extend from a first frame 108a to a second frame 108b. Change plates 191 can be used to increase the weight load in smaller increments relative to the standard weights that make up the weight stack 104a. As such, the weight machine 100 can further comprise a change plate bar 192a. The change plate bar 192a can be connected to any of the moving elements of the weight machine 100, such as the weight stack 104a, the weight bar 102a, the mount 130, the adjustment bar 140a, and the like. In the preferred embodiment, the change plate bar 192a is fixed to the top end 154 of the adjustment bar 140a. The change plate bar 192acan be used as part of the plate-loaded equipment in conjunction with or in lieu of the pulley system.

[0029] In some embodiments, the weight machine 100 can have spring reinforced suspension under the handles 102a and the weight stack 114a for improved usability, noise control, and reduced wear and tear to improve the life of the weight machine 100.

[0030] For brevity and ease of reading, only one side of the weight machine 100 has been described in detail above. However, the weight machine 100 can be made bilaterally symmetrical. Therefore, for any component described above on the first side of the weight machine 100, a person of ordinary skill in the art would know that there can be a corresponding second structure on the opposite side with the same structural configuration for the same function in a mirror image arrangement as shown in the figures and recited in the claims so that the user can perform the exercises with both sides of the body at the same time.

[0031] Therefore, the weight machine 100 can further comprise any one or more combination of the following features: a second weight bar 102b connected to a second weight stack 104b via a second pulley system 106b mounted on a second frame 108b; a second horizonal mount 132b for receiving the second weight bar 102b; a second bar lock 136b to lock the second weight bar 102b at a desired location; a second vertical mount 134b connected to the second horizontal mount 132b; a second adjustment 140b bar attached to the second frame 108b and the second vertical mount 134b for adjusting a height of the second vertical mount 134b; a second mount lock 142b connected to the second adjustment bar 140b and the second vertical mount 134b to set the height of the second vertical mount 134b; a second primary rail 150b operatively connected to the second frame 108b in a immovable manner, wherein the second adjustment bar 140b is slidably mounted on the second primary rail 150b; a second auxiliary rail 160b connected to the second frame 108band the second adjustment bar 140b, and configured to allow the second adjustment bar 140b to slide along the second auxiliary rail 160b; a second dampening pad 170b positioned underneath the second adjustment bar 140b; a second handle 180b mounted at the medial end of the second weight bar 102b, wherein the second handle 180b comprises a second grip bar 181b, a second mounting frame 183b fixed to the second grip bar 18 lb to position the second grip bar 181b parallel to the second elongated bar 120b, and a second rod 182b fixed to the second mounting frame 183b in a perpendicular direction relative to the second grip bar 181b. The second handle 180b can be configured to rotate relative to the second weight bar 102b about a longitudinal axis defined by the second rod 182b, wherein the second handle 180b is spring loaded and configured such that the spring biases the second handle 180b upwards away from the second weight bar 102b in a locked configuration, and compression of the second handle 180b towards the second weight bar 102b releases the second handle 180b to an unlocked configuration for rotation of the second handle 180b to a desired yaw position. The second handle 180b can be configured to tilt about 91 degrees to about 110 degrees in the medio-lateral direction when rotated to be perpendicular to the second weight bar 102b. A second weight stack 114b can be operatively connected to the second weight bar 102b, or the second weight bar 102b can share a common weight stack 114 with the first weight bar 102a. The second weight bar 102b can also be connected to a second change plate bar 192b.

[0032] However, in some embodiments, rather than two weight stacks 114a, a single weight stack 114 can be used as the resistance for both weight bars 102a, 102b. In addition, the first weight bar 102a and the second weight bar 102b can be independently adjustable laterally and vertically.

[0033] The weight machine 100 may further comprise a platform 194 upon which the user can stand to perform the deadlift exercises. The platform 194 can have markings 196 to assist the userin the proper stance for the various deadlift exercises. Preferably, the platform 194 is made of bamboo, but any rigid material can be used such as metal, plastic, wood, and the like.

[0034] EXAMPLE

[0035] In a preferred embodiment, the platform 194 can be square shape having a length of about 3 feet and a width of about 3 feet. The weight bars 102a, 102b can be at a height H of about 3 inches to about 10 inches above the platform, preferably 7 inches. The weight bars 102a, 102b can be adjustable up to a height H of about 18 inches to about 36 inches. More preferably, the height H is adjustable to about 25 inches to about 30 inches. Most preferably, the height H is adjustable from about 7 inches to about 27 inches. The distance D in between the weight bars 102a, 102b (i.e. where the user can stand in between the handles 180a, 180b) can be adjustable from about 15 inches to about 36 inches. More preferably, the distance D in between the weight bars 102a, 102b can be adjustable from about 18 inches to about 33 inches. Most preferably, the distance D in between the weight bars 102a, 102b can be adjustable from about 21 inches to about 31 inches.

[0036] In some embodiments, two weight stacks 104a, 104b are provided, one connected to each weight bar 102a, 102b. Preferably, the total weight of each weight stack 104a, 104b can be up to 400 pounds. Preferably, the total weight of each weight stack 104a, 104b can be up to 300 pounds. Each weight 114a, 114b can be in 15-pound increments with 5-pound and 2.5-pound change plates 191. The primary rails 150a, 150b can be cylindrical with diameters from about 1 inch to about 2 inches. More preferably, the diameter of the primary rails 150a, 150b is about 1.5 inches. The auxiliary rails 160a, 160b can also be cylindrical with diameters of about 0.5 inch to about 1.5 inches. More preferably, the diameter of the auxiliary rails 160a, 160b is about 1 inch.
