BACKGROUND OF THE DISCLOSURE Field of the DisclosureThe disclosure relates to weightlifting rack systems, in particular, weightlifting rack systems having slidable rail supports.
Background and Description of the Related ArtSliding weightlifting rack supports are typically in a fixed angular orientation.
The population has become more aware of the health benefits of exercise and personal fitness. People make going to the gym, fitness club or having a home gym an element of their physical fitness and supplement this physical fitness with lifting weights. A concern regarding the practice of weight lifting has been having a spotter present during the lifting. A user could potentially injure himself or herself by lifting too much weight or accidentally dropping weight on a body part. The spotter's purpose is to help the user finish lifting the weight after the user has become fatigued, or remove the weight should the user not be able to complete the exercise repetition. Many people, however, do not always have spotters available.
To address this issue, Smith machines have been introduced as a way for a user, without a spotter, to lift weights with the added safety of being able to rack the weights at any time during the exercise and to reduce the risk of losing one's balance during the exercise, which can be more difficult when using a free weight barbell (also referred to herein as a bar). The typical Smith machine has a frame with a pair of stationary guide rails. A barbell is attached to these guide rails so that a user can lift the barbell in a vertical up and down motion. Exercises that can be performed on these Smith machines include chest press, shoulder press, leg squats, cleans, bicep curls and triceps extensions.
A major restriction of the Smith machine that guide rails or tracks of the Smith machine are typically in a fixed position and/or angular orientation. Traditional Smith machines require the user to lift the weight in a fixed, vertical up and down orientation. This inhibits the user from lifting the barbell in a full range of motion that can otherwise be accomplished with a barbell, in which the barbell is unrestricted in terms of movement directions. The horizontal freedom of movement associated with a barbell allows for a more natural lifting motion. The horizontal movement limitation of traditional Smith machines can also result on excessive shoulder joint strain during exercise. As such, there is a need for a weightlifting system that provides the user the ability to lift weights in a wider range of motion than with traditional Smith machines with the incorporation of safety of guide rails and ability to rack the weights when the user cannot support the weight himself or herself, for additional safety to the user.
SUMMARY OF SOME EMBODIMENTSSome embodiments disclosed herein relate generally to strength training or weightlifting machines. For example and without limitation, some embodiments disclosed herein relate to a free weight simulating weightlifting system that allows the user to lift weights in a greater range of motion with additional safety support than traditional weightlifting machines or equipment.

Some embodiments disclosed herein relate to a weightlifting system, having one or more rotating support arms that can support carriage members along the length of the rotating support arms. The rotating support arms can be rotatable relative to a fixed arm support. In any embodiments disclosed herein, the support arms can have internal guide rails or carriage members configured to translate along an internal surface of the support arm in the lengthwise direction (which is generally upward and downward, though this may not be in the true vertical direction, because the support arms are rotatable). The weightlifting system can have a bar that extends at least between the two support arms that a user can grip or support. The bar can extend beyond the two support arms so that one or more weight plates can be supported by the bar. The weights can be loaded onto the end portions of the bar, the end portions extending outwardly from the support rails. The weightlifting system can have a latch mechanism used to secure the bar in a desired or predetermined position along the length of the support arms. In the secured position, the bar will be prevented from translating at least in the downward direction until the latch mechanism is disengaged or changed to the free position.
Additionally, in any embodiments disclosed herein, the bar of the weightlifting system can have slidable grip elements or handle elements that are slidable along the axial length of the bar. In any embodiments disclosed herein, the grip elements can be configured such that they slide axially along the length of the bar, but do not rotate about the bar. Conversely, the grip elements can be configured to slide and rotate about the bar.
Described herein is a weightlifting machine having a plurality of safety features for weightlifting, and/or features that can reduce the load exerted on a user's shoulders during bench press exercise. For example, during a squat routine for exercising one's leg muscles, the weightlifting system can be configured to limit the movement of the bar in the lateral directions (left and right, relative to the user's forward facing position). The weightlifting system can also be configured to provide a fixed range of movement of the bar in the forward and aft directions.
It should be noted that any of the features, components, or details of any of the arrangements or embodiments disclosed in this application, including those disclosed below, are interchangeably combinable with any other features, components, or details of any of the arrangements or embodiments disclosed herein to form new arrangements and embodiments.
These and other features, aspects and advantages of this disclosure will now be described in connection with some embodiments of the present disclosure, in reference to the accompanying drawings. The illustrated embodiments, however, are merely examples and are not intended to limit the present disclosure. The following are brief descriptions of the drawings.
Embodiments disclosed herein relate to strength training or weightlifting systems.
In any embodiments disclosed herein, though not required, the weightlifting system embodiments can have a pair of slidable or moveable grip elements 14 (also referred to herein as hand grips) supported by the barbell. As shown in
In any embodiments disclosed herein, the grip elements can have a plurality of ball bearings or slide element positioned between an inner wall portion of the grip elements and an outer wall of the barbell, the bearings or slide element configured to provide smooth rolling or translation along the length of the barbell. The grip elements can generally be made from metal, plastic, rubber, or any combination thereof. For example, the grip elements can be made from metal sleeves (which can be aluminum, steel, or otherwise) that have bearings therein to permit the grip elements to slide or translate along the length of the outer surface of the barbell, and a gripping portion made of plastic and/or rubber, for additional grippiness and/or comfort. Each grip or grip element can have a first linear bearing or slide element at a first end thereof, and a second linear bearing or slide element at a second end thereof.
In any embodiments disclosed herein, the grip elements can be configured to translate along the length of the barbell independently, and can be configured to translate along the length of the barbell without being rotatable about the barbell. In some embodiments, the barbell and/or grip elements can have indexing features, channels, protrusions, and/or other features that permit the translation of the grip elements along the length of the barbell, but prevent the rotation of the grip elements relative to the barbell. Alternatively, in any embodiments, the grip elements can also be configured to generally freely rotate relative to the barbell in addition to translating lengthwise along the barbell.
In some embodiments, the grip elements can have a middle portion, a first end portion, and a second end portion. The middle portion can be configured to receive a user's hand. The middle portion can be knurled or otherwise have features, materials, or components such as a rubber or foam sleeve or overmold designed to provide a slip resistant and/or comfortable grip for the user.
In any embodiments, the middle portion can have an outer diameter of approximately 1.625 in, or from approximately 1.5 in to approximately 1.75 inches. The middle portion can be approximately 5 inches long, or from approximately 4.5 inches to approximately 5.5 inches long. Each of the first and the second end portions can be configured to support a linear bearing or other slide element therein. A retaining ring or clip can be used to secure the bearings or slide elements therein. The overall length of the grip elements can be approximately 10 inches, or from approximately 8 inches to approximately 12 inches, or from approximately 9 inches to approximately 11 inches.
Any embodiment of the weightlifting system disclosed herein can have two grip elements. Additionally, in any embodiments disclosed herein, the grip elements can have locking features or locking element configured to selectively lock the grip elements either rotationally, translationally, or both rotationally and translationally. For example, with the lock activated, the grip elements can be securely positioned in a desired location along the length of the barbell, or so as to be rotationally locked to the barbell. The locking element can be activated by hand without the use of tools, or, in other embodiments, using tools. In some embodiments, the locking element can comprise a quick release clamp, spring clamp, or other type of clamp, or any of the features, components, or details of the limiting elements described herein.
In any embodiments disclosed herein, a locking collar or limiting element can be secured to the barbell in any desired position to provide a limit to a range of movement of the hand grips or grip elements. The limiting element can be positioned at any desired location along the length of the barbell, or multiple limiting elements can be positioned at any desired locations along the length of the barbell. For example, in any embodiments, one, two, or four limiting elements can be positioned at any desired positions along the length of the barbell to limit the range of movement of the grip elements. In embodiments where one limiting element is positioned on the barbell, the limiting element can be positioned in approximately the middle of the length of the barbell.
In any embodiments, the limiting element or elements can be selectively fixable or lockable in any desired position along the length of the barbell. For example, the locking element can be clampable by hand (i.e., without the use of tools) to the barbell at any desired position. A quick release type clamping element (having a cam lever or otherwise) can be used to selectively lock or secure the limiting element in the desired position. When the limiting element is to be moved, the user can simply release the clamp, reposition the limiting element in the desired position, and then engage the clamp. Other locking or securing mechanisms can be used to secure the limiting element in the desired position, such as set screws (hand or tool operated), ball and detent components, spring collars, slip lock collars, and other quick release collars that are typically used with barbells, or otherwise.
In some embodiments, with reference to
Any of the weightlifting system embodiments disclosed herein can have a horizontal barbell assembly 18 configured to movably attach the barbell to the guide rails. In some embodiments, referring to
The engagement elements can be made from metal, including steel, aluminum, or any other suitable material or materials. In some embodiments, a plurality of protrusions can extend from the support base to secure or rack the barbell. In alternative embodiments, the plurality of protrusions can be made from metal, including steel, aluminum, or any other suitable material or materials.
In any embodiments disclosed herein, with reference to
As shown in
In any of the weightlifting system embodiments disclosed herein, the weightlifting system can be configured to limit a range of rotation of the guide rails. For example, with reference to
In any embodiments disclosed herein, the guide rail stops can be configured to prevent the guide rails from rotating past the vertical (or 0°) position, or can be configured to prevent the guide rails from rotating more than 5° past the vertical position. In some embodiments, the guide rail stops can be made from metal such as steel or aluminum, or can be made from any other suitable material.
In any embodiments disclosed herein, as shown in
With reference to
The support base 102 can also have a first stationary support member 114 (also referred to herein as a first stationary support arm) and a second stationary support member 116 (also referred to herein as a second stationary support arm) extending generally upwardly away from the forward extending support members 104, 106. In any embodiments disclosed herein, the first stationary support arm can have a first portion 114a (also referred to herein as a lower portion) that is generally vertically oriented and a second portion 114b that has an angle that is approximately 15° relative to vertical, or from approximately 10° to approximately 20° or more from vertical.
The support base can also have a first and a second angled support members 118, 120 that can span between the first and second forward extending support members 104, 106 and the first and second stationary support members 114, 116, respectively. The first and second angled support members 118, 120 can be approximately 43.11 inches in length, or from approximately 35 inches or less to approximately 55 inches or more in length. An end portion of the angled support members adjacent to the forward extending support members can be angled at approximately 45°. An end portion of the angled support members adjacent to the stationary support members can be angled at approximately 30°. Except otherwise described, the members of the support base can be bolted, welded, or otherwise coupled together.
The first and second portions of the first stationary support arm 114 can be monolithically formed, or can be formed of different tubing members and welded, bolted, or otherwise coupled together. For example,
The first portion 114a can be approximately 18.67 inches long, or from approximately 15 inches to approximately 25 inches long. The second portion 114b can be approximately 54.67 inches long, or from approximately 45 inches to approximately 60 or more inches long. The first portion 114a can serve as a rotational stop or limit for the first rotatable member 126, to prevent the first rotatable member from rotating beyond a predetermined angle relative to the first stationary member 114. For example, the first portion 114a can prevent the first rotatable member 126 from rotating past the vertical orientation, or more than approximately 2°, or approximately 5° past the vertical orientation of the first rotatable member. The second stationary support arm 116 can be similarly configured to have a first portion 116a and a second portion 116b.
In any embodiments disclosed herein, the support base can be configured such that the support base is rigid enough to not need the front and/or rear frame members. For example and without limitation, a top frame member or plurality of frame members, not shown, can be used to interconnect or couple a top portion of the first stationery support arm 114 to a top portion of the second stationery support arm 116 to provide additional, rigid frame support to the first and second stationery support arms. In this configuration, the rigidity of the frame can be significantly increased such that the laterally extending support members 108, 110 can be eliminated to provide free access to the barbell without obstruction.
Any embodiments of the weightlifting system disclosed herein can have a first rotatable member 126 and a second rotatable member 128 that can rotate about a fixed axis relative to the first and/or second stationary support members 114, 116. In some embodiments, the first and second rotatable members 126, 128 can be approximately 73 inches in length, or from approximately 65 inches or less to approximately 85 inches or more in length. In any embodiments, the first and second rotatable members 126, 128 can be shorter, for example, approximately 50 inches in length, or from approximately 40 inches or less to approximately 60 inches or more in length.
With reference to
In some embodiments, a first bracket and a second bracket can be used to support each shaft member. The brackets can be bolted, welded, or otherwise coupled with or secured to the support members 114, 116 and have an opening therein configured to support the shaft members 132, 134. Additionally, the support bracket or member 130 can be coupled with a top portion of the first rotate alarm 126 and a top portion of the second rotatable arm 128 to cause the first and second rotatable arms 126, 128 to rotate and move simultaneously.
In this configuration, the first and second rotatable members 126, 128 can be configured to be movable between a first, stowed position, as shown in
Any of the embodiments of the weightlifting system disclosed herein can be configured to limit the range of rotation or the angle of rotation of the first and second rotatable members 126, 128. For example and without limitation, as shown in
Conversely, an upper portion 126b of the first rotatable member 126 can be configured to contact and/or abut an upper portion 114b of the first stationary member 114 when the first rotatable member 126 has reached the first or stationary position, thereby limiting the rotational range of the first rotatable member. Similarly, an upper portion 128b of the first rotatable member 128 can be configured to contact and/or abut an upper portion 116b of the first stationary member 116 when the first rotatable member 128 has reached the first or stationary position, thereby limiting the rotational range of the first rotatable member.
In any embodiments disclosed herein, the first and second rotatable members 126, 128 can be configured to rotate from a first position, that can be approximately 15° relative to vertical, or from approximately 10° to approximately 20° relative to vertical, to a second position that is approximately 0° relative to vertical, or which is approximately 5° forward leaning relative to vertical, or is approximately 5° backward leaning relative to vertical. In any embodiments disclosed herein, the first and second rotatable members 126, 128 can be configured to rotate through a range of approximately 15° or more, or approximately 20° or more, or between approximately 10° and 30° relative to the stationary members.
However, the embodiments of the weightlifting system disclosed herein are not so limited and can be designed and configured to permit the rotation of the first and second rotatable members through any desired angular limits. Additionally, in any embodiments disclosed herein, the stationery members can be vertically oriented and the rotating members can rotate away from the stationery members from an initial position that is approximately vertically oriented through a range of approximately 15° or more, or approximately 20° or more, or between approximately 10° and 20° relative to the stationary members and relative to the vertical orientation.
When the first and second rotatable members 126, 128 are positioned in any position away from the stowed or first position, the user using the weightlifting apparatus can exert an upward force on the bar or permit gravity to move the bar downward so as to move the bar freely in the upward and downward directions (as represented by arrows A3 and A4 in
In any embodiments disclosed herein, the weightlifting system such as weightlifting system embodiment 100 can be configured such that the first and second rotational members 126, 128 are biased to move (for example, under the force of gravity) toward the first or stowed position at a majority of the range of positions of the first and second rotational members 126, 128. In some embodiments, the first and second rotational members 126, 128 can be configured to remain in the second position wherein the first and second rotational members 126, 128 are either vertically oriented or rotated past the vertical position relative to the stationary members 114, 116.
With reference to
With reference to
Another benefit of this system is that, while the barbell is being moved up and down during the exercise, the first and second rotatable members 126, 128 can simultaneously rotate about the first and second shafts or axes 132, 134 to permit multiple planes of motion simultaneously during the exercise (i.e., in the fore and aft directions as well as in the upward and downward directions). Additionally, the system has the added benefit of safety features which permit the user to safely rack or support the weight when the user's strength can no longer support the weight.
In any embodiments disclosed herein, the weightlifting apparatus can have one or more safety features. For example, the weightlifting apparatus can have one or more features configured to allow a user to rack or suspend the bar in the event that the user does not have enough strength to return the bar to the initial position of the bar, and/or prevent the bar from descending toward the user. For example, in some embodiments, the weightlifting apparatus can have one or more safety latches coupled with the bar that are configured to advance into and engage with one or more openings or slots formed in the stationary support members. The user can advance the safety latches into the openings by moving the entire bar assembly and the rotatable support members toward the stationary support member so that each of the safety latches advance into the openings or slots formed in the stationary support members.
In some embodiments, the safety latch elements and the rotatable support members can be configured so that the safety latch elements can be rotatable relative to the carriage members and, hence, rotatable relative to the rotatable support members so as to be selectively advanceable into slots or openings formed in the rotatable support members. This can be achieved, without limitation, by making the latch members rotate when a user rotates the barbell assembly so that the latch members are and selectively engagable with slots positioned on a wall of the first rotatable member 126 and the second rotatable member 128. The latch elements can be engagable by rotating the barbell member 140 so that the latch elements are able to extend into slots formed in the rotatable members. The latching mechanism and the barbell could be secured to the rotatable support members regardless of the rotational position of the rotatable member relative to the stationary member of the weightlifting system.
Additionally, in any embodiments, such as the illustrated embodiment, the weightlifting system can be configured such that the user does not have to rotate the bar to engage the safety latch with the one or more slots. Rather, the latch elements can be configured such that the safety latch elements will automatically engage with one or more of the slots when the rotatable support member is positioned adjacent to or near to the fixed arm such that the safety latches are advanced into the slots when the rotating arm is against or in close proximity to the fixed arm. As in the illustrated embodiment, the latch elements can be configured to extend through openings in the rotatable support member regardless of the angular orientation of the bar or otherwise so that all a user needs to do is to rotate the rotatable support members against the stationary support members to advance the latch elements into the openings or slots in the stationary support members.
In this configuration, to disengage the safety latch or latches from the slot or slots, the user would rotate the rotatable support members away from the stationary support members. The weightlifting apparatus can be configured such that, when the safety latch is in the first, or stowed position, the bar can be freely moved relative to the rotatable support member regardless of the position that the rotating arm is in relative to the fixed arm. In other words, in some embodiments, the bar can be translated relative to the slot in the rotatable support member even if the rotatable support member is in the first position against or proximal to the fixed arm.
With reference to
For example and without limitation, a body portion 174 of the first carriage member 164 can have a latching element 176 extending away from the body element 174. The second carriage member 166 can be similarly configured to have a second latching element 178 extending from a body portion 178 of the second carriage member 166. Latching elements 176 and 178 can be configured to extend into any of the desired slots 170 of the first stationary member 114 and the slots 172 of the second stationary member 116 when the first rotational member 114 at second rotational member 116 are moved to the first position in which the first and second rotational members 126, 128 are adjacent to or abutting against the first and second stationary members 114, 116.
In any embodiments disclosed herein, the first latching element 176 can have a tabbed portion 182 extending in the downward direction at an end portion 176a of the first latching element 176. The tabbed portion 182 can be configured to engage the wall portion of the front face 114a of the first stationary member 114 so as to prevent the latching mechanism from becoming inadvertently disengaged from the first stationary member 114. A second latching mechanism 178 can be similarly configured to have a tabbed portion that can engage with the wall portion of the front face 116a of the second stationary member 116.
As mentioned, the carriage members can be configured to translate along an inside surface of the rotatable members of the weightlifting system.
The body portion 174 of the carriage assembly 164 can be sized and configured to fit inside of and translate within an inside surface of the rotatable support members 126, 128. In some configurations, the rotatable members 126, 128 can be made from 3 inch by 3 inch square profile steel tubing having a wall thickness of between approximately 0.120 and 0.250 inch thickness. Body portion 174 can be sized and configured such that, when the wheels 190 are assembled to the body element 174, the carriage assembly 164 will be able to roll smoothly within an inside surface of the rotatable members 126, 128. In some embodiments, each of the wheels 190 can be sized and positioned such that only a small portion of the wheels extend past the adjacent and perpendicular surfaces. For example and without limitation, in any embodiments disclosed herein, the wheels 190 can be sized and positioned such that the contact surface 190a of the wheels extends approximately 0.10 inch past the adjacent, perpendicular surface of the body element 174, or from approximately 0.05 in to approximately 0.2 inch past the adjacent, perpendicular surface of the body element 174.
In any embodiments disclosed herein, the body portion 174 of the carriage assembly 164 can have a height (i.e., distance between the top surface 174a and the bottom surface 174b) of approximately 6 inches, or between approximately 4 inches (or less) and approximately 8 inches, or greater. Additionally, in any embodiments, the body portion 174 can have a width in both the lateral direction and in the forward and aft direction of approximately 2.5 inches, or from approximately 2 inches to approximately 4 inches or more, depending on the size of the wheels, the size of the barbell assembly, and the size of the inside surfaces of the rotatable members. Additionally, in any embodiments, the wheels can have a diameter of approximately 1 inch or less, or approximately 1.05 inch, or from approximately 1 inch to approximately 1.25 inches, or from approximately 2 inches to 2.5 inches or greater.
Each of the four main surfaces of the body portion 174 of the carriage assembly 164, i.e., the front surface 174c, the rear surface 174d, and the first and second side surfaces 174e, 174f, can each be configured to support four wheels 190. In the illustrated embodiment, the carriage assembly 164 can have a total of 16 wheels 190. Each of the wheels can be sized and positioned such that a contact surface 190a of each of the wheels 190 can extend through a surface of the body portion 174 that is adjacent to a normal to the surface on which the wheels 190 or position. For example, with reference to
In any embodiments disclosed herein, however, the carriage assembly can have any number of wheels. For example and without limitation, any weightlifting systems disclosed herein can have eight total wheels supported by the carriage assembly 164, with two wheels on each of the four main surfaces. The wheels in this configuration can be sized and positioned so as to extend past the adjacent, perpendicular surfaces of the body portion 174 on each of the two perpendicular, adjacent sides of the body element 174. Alternatively, in any embodiments disclosed herein, the carriage assembly can have 32 total wheel supported by the carriage assembly 164, with eight wheels on each of the four main surfaces. Further, in any embodiments, the body portion 174 can have more wheels along one edge of the body portion that another edge of the body portion.
With reference to
An opening 192 can extend through the body portion 174 of the carriage assembly 164 from the first side surface 174e to the second side surface 174f. The opening can be configured to permit the barbell assembly 160 to extend therethrough. In this manner, the opening 192 can support the barbell assembly 160 or can be used to couple the barbell assembly 162 with the carriage assembly 164 so that the carriage assembly 164 will translate up and down relative to the rotatable members 126, 128, as the barbell assembly 160 is moved up and down relative to the rotatable members 126, 128, when the weightlifting system is in a second or free state.
Additionally, as shown in
The wheels 190 can be formed from the high-strength plastic, a fiber reinforced plastic, or any suitable metal material or combination thereof. Additionally, in any embodiments, the carriage member can be formed from any suitable rigid material, including aluminum, steel, reinforced plastic, or any other composite material or combination thereof. Any embodiments of the weightlifting system can have one or more low friction pads that are configured to slide relative to the inside surface of the rotating members in place of one or more of the wheels, or a combination of wheels and low friction pads. The low friction pads can be made from any suitable low friction material, including nylon, acetal, polytetrafluoroethylene, or any other suitable material. A bench, similar to the bench types described above, can be used with any of the embodiments disclosed herein, including the weightlifting system 100.
In any embodiments disclosed herein, plastic or rubber pads or other suitable components or materials can be positioned between the upper portion of the rotatable members 126, 128 and the stationary members 114, 116 to soften the impact between the rotatable members and the stationary members as the rotatable members rotate into contact with the stationary members. Similarly, plastic or rubber pads or other suitable components or materials can be positioned between the lower portion of the rotatable members 126, 128 and the stationary members 114, 116 to soften the impact between the rotatable members and the stationary members as the rotatable members rotate into contact with the stationary members. Additionally, in any embodiments disclosed herein, the weightlifting apparatus can have one or more safety stops, which can be pins, shafts, brackets, or other components that can be inserted in any one of a multitude of positions along a front surface of the rotatable support members to provide safety stops to limit the range of travel in the downward direction of the bar.
