Patent Application
20240278057
The present invention relates to exercise equipment. More particularly, but not exclusively, it relates to a weight lifting assembly.
Exercise equipment is often utilised by people aiming to get fitter and stronger. Weight lifting equipment may be useful, to help users develop muscle, and improve bone density.
Some exercise equipment may be particularly useful, to help with rehabilitation to increase mobility, strength, and quality of life. Exercise equipment aimed at rehabilitation may help a person regain their independence and shorten recovery time.
However, as weight lifting equipment inherently involves heavy components, safety is a key concern for the users of the equipment. Injuries may occur if weight plates are dropped, especially during adding and removing weights to barbells. Users may also find it difficult to assume particular exercise positions, such as lying on their back for bench presses while supporting the exercise equipment.
Users of weight lifting equipment may often require assistance to help them during their work out. For example, spotters may be necessary to help a lifter support heavy barbell weights while the lifter gets into position.
In other cases, a weight lifter may use cage racks to help support their barbell weights while getting into their exercise position. It may be desirable for weight lifting equipment to be safer and simpler than traditional equipment presently available.

The invention will now be described by way of example only and with reference to the drawings in which:
With reference to
The weight lifting assembly 1 is preferably formed from metal, for example aluminium. It is anticipated that the weight lifting assembly 1 can be formed from different metals. For example, the stands 2 or elongate members of the stands 2 may be formed from aluminium, while the cross bar 3 is formed from steel. However other suitable materials with sufficient stiffness and durability may be used.
The weight lifting assembly 1 is preferably sized and configured to be lifted by users as a whole.
The weight lifting assembly 1 comprises two vertical stands 2 horizontally spaced apart from each other in use. Preferably the spaced apart vertical stands 2 are spaced a width greater than the shoulder width of a user of the weight lifting assembly 1.
The stands 2 support the cross bar 3. The stands 2 are attached to the ends of the cross bar 3, or are alternatively attached towards the ends of the cross bar. It is anticipated that stands 2 having different heights, to accommodate different users, uses, or exercises, may be provided.
In the most preferred configurations, the vertical position or height of the cross bar 3 relative to the base 5 can be adjusted, described in more detail later.
The stands 2 preferably comprise weight receiving members 4 and a base 5 for providing a stable support for the weight lifting assembly 1.
The weight lifting assembly 1 comprises stands 2 and a cross bar 3 having an inherent weight. It should be appreciated that the weight lifting assembly 1 is suitable for use with no additional weight plates 10 added to the assembly as shown in
Alternatively, the user can add, or remove standard weights 10 to the weight lifting assembly 1 as shown in
In the preferred configuration, the weight receiving members 4 are located towards a lower end 8 of the stands 2 of the weight lifting assembly 1, so that weights 10 may be loaded towards the lower end 8 of the stands 2. Preferably, the weight receiving members 4 are on a lower horizontal plane than the cross bar 3.
A weight lifting assembly 1 having weights 10 loaded towards the lower end 8 of the stands 2 has a low centre of gravity, resulting in improved stability. Additionally, a weight lifting assembly 1 configured for loading weights 10 at the lower end 8 of the stands 2 improves the safety of the assembly for users, as weights 10 do not need to be lifted high to be loaded onto the assembly. Loading weights 10 onto the weight lifting assembly 1 towards the lower end 8 of the stand 2 may reduce the likelihood of back injuries, or if the weights are dropped, the weights may cause less damage to the ground or the assembly.
As weights 10 have been loaded onto the weight receiving members 4 of the weight lifting assembly 1, a useful advantage of the present invention is its ability to adjust the height of the cross bar 3 along the length of the stands 2 without having to remove the weights 10 off the assembly. In contrast, on a traditional barbell and rack assembly, weights are generally located at the ends of the barbell, so users have to remove the weights to adjust the height of the barbell relative to the rack.
The weight receiving members 4 comprises a distal end 11 and a proximal end 12 as shown in
In the preferred configuration, the weight receiving members 4 are cylindrical.
In the preferred configuration, the weight receiving members 4 are substantially horizontal. The weight receiving members 4 in a substantially horizontal configuration helps the weights 10 stay on the weight lifting assembly 1. Alternatively, the distal end 11 of the weight receiving pin 4 is higher than the proximal end 12 (not shown). In this configuration, the weights 10 are biased by gravity towards the proximal end 12 of the weight receiving pin 4, which is another configuration which helps the weights 10 stay on the weight lifting assembly 1.
The weight receiving members 4 are configured to receive weights 10. Optionally a weight collar 25 can be inserted onto the distal end 11 of the weight receiving pin 4 to secure the weights 10 onto the weight receiving pin 4.
The length of the weight receiving members 4 are preferably long enough to support multiple weights 10. In the preferred configuration, the length of a weight receiving member 4 is configured to support three weights 10 as represented in
In
An example configuration as shown in
Preferably, a locking mechanism 13 locks the cross bar 3 with the stand 2, so the position of the cross bar 3 with respect to the stands 2 remains fixed when an upwards force is applied to said crossbar in a locked position, such as when a user lifts the assembly off the ground by the cross bar.
In one configuration of the weight lifting assembly 1, the locking mechanisms 13 lock the cross bar 3 with the stands 2 in a plurality of predetermined positions.
The stand 2 preferably comprises a plurality of locking apertures 9 along the length of the stand 2. The locking mechanisms are configured to engage with the locking apertures of the respective stand to lock a respective end of said cross bar 3 to the stand. The position of the locking apertures 9 corresponds to the different positions or heights the cross bar 3 can be adjusted to relative to the base 5.
In one configuration, the plurality of locking apertures 9 are equally spaced along the stand 2. Preferably, the locking apertures 9 are spaced sufficiently so that the user is able to adjust the position of the cross bar 3 without misaligning the positions of the cross bar on each stand.
Alternatively, the cross bar 3 locks with the stands 2 at a continuous range of positions along the stands. The cross bar 3 can be secured to the stands 2 by increasing friction between the cross bar and the stand. In one configuration, a clamping mechanism can secure the cross bar 3 to the stands 2 (not shown).
In the preferred configuration, as illustrated in
The weight lifting assembly 1 in the preferred configuration comprises a locking mechanism 13 at each of the two junctions between the cross bar 3 and the stands 2 as illustrated in
The locking mechanism 13 of the weight lifting assembly 1 in the preferred configuration is best shown in
The locking mechanism 13 is preferably biased to a locked position by a biasing mechanism 17. In the locked position the locking pin 16 engages with and is secured to the stand 2. The internal locking pin 16 engages with the respective stand 2 to prevent the movement of the cross bar 3 along the stands.
The internal locking pin 16 is configured to selectively engage with any of the locking apertures 9 in the stands 2.
Preferably, the cross bar 3 comprises a cavity 28 at least partially housing the internal locking pin 16, and the biasing mechanism 17.
The internal locking pin 16 comprises a first end 29 and a second end 30. The first end 29 of the internal locking pin 16, engages with locking apertures 9 of the stand 2. The locking apertures 9 of the stands 2, via apertures 9 is configured to receive a first end 29 of the internal locking pin 16.
The biasing mechanism 17 biases the internal locking pin 16 in a direction towards the stand 2 towards the locked position. Most preferably, the biasing mechanism 17 is a spring such as a coil spring as illustrated in
The weightlifting assembly 1 comprises a release mechanism for releasing the internal locking pin 16 from the locking apertures 9 of the stand 2. In one configuration, to disengage the locking mechanism 13, the internal locking pin 16 is forced in a direction away from the stands 2, as shown by arrow 31.
Each locking mechanism 13 preferably comprises a guide casing 14 at each end of the cross bar 3 to help secure the cross bar 3 to the stands 2 as shown in
The stand 2 preferably passes through the guide casing 14. The guide casing 14 preferably comprises a body around a portion of the stand. The body of the guide casing 14 having some length, preferably extends partially along the stand 2. The guide casing 14 is preferably elongate and extends parallel to a vertical axis of the stand a distance.
The guide casing 14 couples the cross bar 3 with the stands 2 to allow a single degree of freedom of translational sliding of the cross bar along a vertical axis of the stands 2 during height adjustments. Preferably, the guide casing 14 helps maintain the cross bar 3 in a generally horizontal orientation so that the cross bar is locked at the same height with respect to the two stands 2. The cross bar 3 is substantially perpendicular to the respective stands 2, when it is in a generally horizontal orientation.
Optionally, the guide casing 14 extends from the bar towards the lower end 8 of the stand 2 as illustrated in
The guide casing 14 concealing at least a portion of the locking mechanism 13 also helps reduce ‘pinch points’ where fingers or loose articles may get trapped, thus improving the safety of the exercise equipment. The guide casing 14 also conceals the locking mechanism 13 improving the aesthetic appeal of the weight lifting assembly 1.
Preferably the locking mechanism 13 at the two junctions of the cross bar 3 and the stands 2 can be operated simultaneously to allow for a substantially vertical adjustment 27 of the cross bar.
In the preferred configuration, a handgrip 15 is attached to the internal locking pin 16. The hand grip may be connected to the respective pin by one or more fastening means 18. At least a portion of the fastening means 18 travels within a side cavity 32 of the cross bar 3. A portion of the fastening means 18 moves from a first position in the side cavity 32 from a locked position, to a second position in the side cavity to an unlocked position.
Preferably, if the hand grip 15 is forced towards a releasing direction 31, the connected internal locking pin also moves in the direction 31. In one configuration, the releasing direction 31 is away from the stand as illustrated in
Using a handgrip 15 to operate the locking mechanism 13 improves the aesthetic appeal of the weight lifting assembly 1, as the internal elements of the locking mechanism operate while being hidden. The locking mechanism 13 of the preferred configuration allows the user to unlock the cross bar 3 from the stands 2 and thus adjust the height of the cross bar relative to the ground.
Preferably the handgrip 15 is a material different from the cross bar 3, such as a polymer, rubber or other suitable material.
The locking mechanism 13 described makes the height adjustment of the weight lifting assembly 1 intuitive and simple to use, especially for new users and in an exercise class environment where simple and quick height adjustability may be desired.
In use, the weight lifting assembly 1 with an adjustable cross bar 3 is advantageous as it may reduce injury to the user when they are getting into position for their exercise. For example, a user may first lie on their back on a bench under the cross bar 3 of the weight lifting assembly 1 as illustrated in
It is anticipated that other locking mechanisms can be used to adjust the cross bar 3 relative to the stands 2 of the weight lifting assembly 1. For example, a ratchet system may be used as a locking mechanism.
The stand 2 is in one configuration generally hollow. The stands 2 optionally comprise end caps 19 to enclose any sharp edges and for aesthetic appeal.
The cross bar 3 optionally comprises rubber or plastic grips around the cross bar 3 (not shown) for user comfort. Grips around the cross bar 3 may also help improve the user's control of the weight lifting assembly 1 during lifting by reducing the likelihood of the cross bar slipping during use, and/or thick hand grips help engage a range of muscle groups.
The base assembly 5 as best shown in
The base member 20 optionally comprises a protective layer 21. The protective layer 21 can cover a portion of the base member 20 as represented in
In the illustrated configuration, the base assembly 5 comprises a support member 24 for supporting the vertical elongate member of the stand 2 from the base member 20. The support member 24 is attached to the base member 20.
In the illustrated configuration, the stand 2 comprises an attachment member 22 having a recess 23 as best shown in
In the illustrated configuration, the lower ends 8 of the vertical elongate members are spaced above the ground to allow weights 10 to fit beneath the vertical members of the stands 2. The elongate member of the stand 2 and the weights 10 may be generally in the same vertical plane to improve the compactness of the weight lifting assembly 1, and/or the stability of the assembly.
In the illustrated configuration, the lower end 8 of the elongate members of the stands 2 is at a distance from the base member 20 greater than the radius of the biggest weight 10 to be loaded onto the weight lifting assembly 1.
In one configuration, the vertical elongate member of the stand 2 and the proximal end 12 of the weight receiving member 4 of the stand are generally in the same vertical plane. An advantage of the stand 2 and weights 10 on the same plane, is to improve the compactness of the weight lifting assembly 1, and/or the stability of the assembly.
Alternatively, the vertical member of the stand 2 and the proximal end 12 of the weight receiving member 4 of the stand 2 are not in the same vertical plane.
It is anticipated that the weight lifting assembly 1 may alternatively comprise stands 2 with a lower end 8 of the vertical elongate members extending to the ground or base member 20.
In the illustrated configuration, the attachment member 22 is connected to the elongate member of the stands 2 as illustrated in
As represented in
A useful advantage of the present invention is the adjustability of the cross bar 3 to tailor the weight lifting assembly 1 for users of different heights and/or to accommodate different exercises including other equipment under the cross bar 3.
The cross bar 4 may be tailored to users confined in wheelchairs as the cross bar 3 can be adjusted to a suitable height, towards the lower end 8 of the stand 2.
It is anticipated that the cross bar 4 can also be adjusted to different heights for a variety of exercises. For example, the cross bar 4 of the weight lifting assembly 1 can be adjusted to a height suitable for bench presses as shown in
As illustrated in
The profile of cross-section the slot 33 of the stand 2 is substantially rectangular. The slot is substantially parallel to a vertical axis of the stand. The slot 33 stiffens the stand 2. The slot 33 may help to stiffen the weight lifting assembly 1 by allowing the ends of the cross bar 3 to securely engage with the stands 2 and to limit flex and twisting of the cross bar 3 when lifting. As shown in
A useful advantage of the present invention is the ability of the slot 33 of the stands 2 to conceal the locking mechanism 13, resulting in fewer ‘pinch points’. The slot 33 of the stands 2 also helps improve the aesthetic appeal of the weight lifting assembly 1, as the engagement of the internal locking pin 16 with locking apertures 9 located in the recess of the stand is hidden from view.
The weight lifting assembly 1 can be disassembled to allow for more efficient storage as shown in
The weights 10 can remain on the disassembled stand 2 as represented in
A weight lifting assembly 1, 101 configured to be disassembled is particularly useful when the assembly is used in a multipurpose workout area or in a limited space such as in an exercise class or at home where it is desirable to put away and store the exercise equipment after use.
The base 55 of the embodiment 101 of
In the illustrated embodiment, the weight receiving member 4 is attached to the elongate member 6 of the stand. The weight receiving member 4 is received through an aperture through the elongate member 6. The weight receiving member 4 is attached to the elongate member 6 near to a bottom end 8 of the elongate member 6. The weight receiving member 4 may extend from two opposed sides of the elongate member/stand. This allows weights to be received on the weight receiving member 4 on each side of the elongate member of the stand.
As shown in
With the weight receiving member 4 received through the elongate member adjacent to an end of the elongate member 6, the weight receiving member 4 may also provide a fixing point for fixing the base 55 to the elongate member 6. As shown in
