During exercise, such as weightlifting or bench pressing, a person may wear a belt to provide lower back and core support. The weightlifting belt reduces the risk of injury when performing strenuous exercise, such as weightlifting. For example, a person who performs a squat may wear a weightlifting or powerlifting belt to reduce the risk of injury to their lumbar area or their lower back.
Weightlifting belts may be of a variety of widths, but may generally be wider than belts that are typically worn in beltloops of a pant. The length of the weightlifting belt may be any suitable length, and in some cases, may depend on the girth of the wearer. Regardless of the length and width of the weightlifting belt, it is desirable for the belt to be worn taught across the wearer's waist and/or abdomen. A belt that is loose may not provide an optimum level of support to the wearer. As a result, it is desirable to wear a weightlifting belt with a near precise tightness.
Buckles are used for wearing a weightlifting belt. The buckles generally engage spaced holes in the weightlifting belt to hold the weightlifting belt wrapped around the user of the weightlifting belt. The weightlifting belts typically have a spatial distance between holes (e.g., spatial periodicity) that allows for a reasonable, but imperfect fit of the weightlifting belt. In other words, conventionally, weightlifting belts are worn with lengths that increment according to the distance between the holes formed on the weightlifting belt. Thus, conventional weightlifting belts and/or buckles may not allow a perfect fit, if that perfect fit corresponds to an intermediary distance between any two belt positions, as defined by the holes disposed on the weightlifting belt.
Additionally, conventional buckles may be flimsy and may unbuckle during use. In some cases, the buckles may snag other items and come unbuckled. Furthermore, due to requirements of ruggedness, conventional weightlifting buckles may be relatively expensive and may be constructed with more expensive materials that provide for a relatively high level of ruggedness.
The detailed description is described with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The same reference numbers in different figures indicate similar or identical items.
Examples of this disclosure include a buckle for a weightlifting or powerlifting belt. The buckle may be used to hold two ends of the weightlifting belt in a manner such that the weightlifting belt is held in a wrapped orientation around a user of the weightlifting belt. In other words, the buckle, as disclosed herein, may allow for a weightlifting belt to be held in a substantially oval and/or circular shape, snugly around a user of the weightlifting belt. The weightlifting belt may be of any suitable type (e.g., 10 mm belt, 13 mm belt, etc.) and material of construct (e.g., leather, polymer, etc.).
The buckle, as disclosed herein, may allow for a more precise and/or snug fit for a user of weightlifting belts than conventional buckles. The buckle, as disclosed herein, may allow for a wrapped length that is intermediary between the holes disposed on the weightlifting belt. In other words, the buckle can be adjusted to provide a more precise fit than conventional buckles for weightlifting belts.
In some examples, the buckle for a weightlifting belt may include an adjustment mechanism that allows for the user of the buckle to adjust the fit of the belt to a precision that is less than the distance between the holes on the weightlifting belt. The adjustment mechanism may, in some cases, be a worm screw seated in a corresponding set of threads that allows for fine adjustment of the tightness of the weightlifting belt. “fine adjustment,” as used herein, refers to the adjustment of the tightness of the weightlifting or other belt that is at a level that is more precise or granular than what merely fixedly engaging the holes disposed on the weightlifting belt would allow. Although the adjustment mechanism discussed in this disclosure is the worm screw, it should be understood that the disclosure contemplates other fine adjustment mechanisms, such as ratcheting mechanisms, sliding mechanisms, clamping mechanisms, or the like.
In some cases, the buckle includes a car attached to a body, where the car can move relative to the body. The car engages the holes disposed on the weightlifting belt. Because the car, which holds one end of the weightlifting belt, can move relative to the rest of the buckle, including the body, the movement of the car can be used for fine adjustments of the snugness or tightness of the weightlifting belt. A user may be able to adjust the relative position of the car, and therefore control the snugness of the weightlifting belt, by rotating the worm screw disposed between the body and the car of the buckle. Threads that engage the worm screw may be disposed in one or both of the body and/or the car.
The buckle, as disclosed herein, has a sleek and compact design that minimizes material usage and minimizes snag points that may catch surrounding objects (e.g., exercise equipment) and unbuckle. By using less material, the buckle is cost effective, without unneeded parts or bulk. The sleek design allows the belt to conform more closely to the contour of the weightlifting belt that it holds, resulting in an aesthetic look compared to conventional buckles. Additionally, the buckle is easily fabricated due to its compact design, further leading to cost-effective manufacture.
The buckle, as disclosed herein, due to its compact and durable design, may be fabricated and/or manufactured from a wide variety of materials. Unlike conventional buckles for weightlifting belts, the novel buckle disclosed here need not be manufactured only from metals. Because of its robust design, the buckle may be fabricated from any variety of metals, as well, as any variety of plastics or other polymeric materials. Additionally, the ability to use nonconventional materials allows for the use of any variety of fabrication mechanisms. Conventional buckles are made substantially from metal, where parts of the conventional buckle is machined. The Buckle, as disclosed herein, may be fabricated from conventional materials, but may also be fabricated from more cost-effective plastics and/or other polymeric materials using lower cost fabrication techniques, such as injection molding and/or 3D printing.
The buckle, as disclosed herein, may be fabricated in any suitable manner, including machining, molding, casting, 3D printing, or the like. As 3D printing technology becomes more ubiquitous, the disclosure further contemplates the design of the buckle disclosed herein being sold to consumers, who in turn may 3D print the buckle in their own homes or gyms.
In some cases, the buckle may also include a magnet disposed on a lever of the buckle that allows for an extra-secure buckling of the buckle. The magnet may engage with a wedge of the buckle, if the wedge is constructed from a magnetic material, such as iron, steel, cobalt, nickel, chromium, or the like. Alternatively, another magnet may be disposed on the wedge to magnetically engage the magnet disposed on the lever of the buckle. In this way, there is an additional force (e.g., a magnetic force) that cooperates with the latching mechanism of the lever and wedge to keep the buckle from unbuckling, such as from snagging another object.
The buckle 100 may further include a fastener plate 118 that is fixedly disposed on the wedge 102 of the buckle 100. The fastener plate 118 may have edges 120 therein that define holes 122. The fastener plate 118 may have any suitable number of holes 122 formed therein. For example, as shown, the fastener plate 118 may have four holes 112 therein. In other cases, the fastener plate 118 may include two holes or six holes. The holes 122 in the fastener plate may correspond roughly to holes of the weightlifting belt. For example, a typical weightlifting belt may have two sets of holes along the length of the weightlifting belt. The holes 122, as defined by the edges 122 of the fastener plate 118, may be spaced in a manner that corresponds with the spacing of the holes on the weightlifting belt. The fastener plate 118 may be attached to one end of the weightlifting belt using any suitable mechanism, such as a screw and nut through the holes 122, hexagonal bolts, other fasteners, or the like. In other cases, the fastener plate 118 may be attached to the body 106, holding one end of the weightlifting belt, by a threaded insert. In still other cases, the fastener plate 118 may be attached to the body 106, holding one end of the weightlifting belt, by machine threading into the body 106.
The buckle 100 may further include a car 124 that is movably coupled to the body 106 of the buckle 100. The car 124 may be configured to move along rails 126 of the body 106. In other words, the rails 126 of the body 106 may serve as guides along which the car may be able to move. A user of the buckle 100 may move the car 124 relative to the body 106 for fine adjustment of the effective length of the weightlifting belt to control the snugness thereof. In other words, by moving the car 124 relative to the body 106, a user can adjust the tightness of the weightlifting belt with a granularity that is more precise than the granularity possible by the spacing of the holes on the weightlifting belt alone.
The car 124 may include one or more legs 128, which protrude from a bottom surface of the car 124. The legs 128 are configured to fit within the holes of the weightlifting belt to hold the weightlifting belt to the buckle 100. The car 124 may have any suitable number of legs 128. In some cases, the car 124 may have four legs 128. In other cases, the car 124 may have one, two, three, six, or eight legs 128. The legs 128 may be spaced from one another with a spacing that corresponds to the spacing of holes on the weightlifting belt that is to be held by the buckle 100. For example, the weightlifting belt may have holes that are 1 inch apart. In that case, the legs 128 of the car 124 may also be spaced substantially 1 inch apart. In some cases, the weightlifting belt may have holes that are disposed as pairs along the length of the weightlifting belt. In this case, in some embodiments, the car 124 may have four legs 128, which together engage two sets of holes running along the length of the weightlifting belt.
In some cases, the legs 128, as disposed on the car 124, may include feet 130. The feet 130 may enable the corresponding legs 128 to not slip out of the holes on the weightlifting belt. Thus, the feet 130 enable the legs 128 to more reliably hold onto the weightlifting belt. In some cases, the all of the legs 128 of the car 124 may have feet 130. In other cases, one some of the legs 128 may have feet 130. In yet other cases, none of the legs 128 may have feet 130.
As depicted in
A user of the buckle 100 may rotate the worm screw 300 to move the car 124 to adjust the distance between the car 124 and the fastener plate 118. It is the control of the distance between the car 124 and the fastener plate 118 that allows for fine adjustments to the snugness of the weightlifting belt, as worn by the user. It should be understood that the distance that the car 124 can move relative to the fastener plate 118 is any suitable distance. In some cases, the allowed movement of the car 124 may be at least the distance between holes on the weightlifting belt. In other cases, the allowed movement of the car 124 may be at least half the distance between holes on the weightlifting belt. In some cases, the car 124 may be able to move at least 1 inch relative to the body 106 and/or the fastener plate 118. In other cases, the car 124 may be able to move at least 0.5 inches relative to the body 106 and/or the fastener plate 118. In some cases, the car 124 may be able to move at least 0.25 inches relative to the body 106 and/or the fastener plate 118.
Although a particular mechanism, namely the worm screw 300, is shown to provide fine adjustments to the weightlifting belt worn with the buckle 100, it should be understood that the disclosure contemplates other mechanisms for fine adjustment of the snugness of the weightlifting belt. For example, other mechanisms my be sliders with brakes or slots to move the car 124 relative to the rest of the buckle 100. In other cases, a rachet, a zipper, and/or a clasp mechanism may be used to adjust the car 124 relative to the fastener plate 118.
The parts of the buckle 100, such as the wedge 102, lever 104, body 106, edge elements 108, car 124, worm screw 300, or the like, may be fabricated from any suitable materials. In some cases, the parts of the buckle 100 may all be fabricated from the same material and in other cases, the parts may be fabricated from different materials. The parts, as discussed herein, may be fabricated from any variety of metals (e.g., aluminum, stainless steel, steel, etc.), ceramics, polymers, and/or composite materials. Due to the robust and sleek design of the buckle 100, a variety of lower-cost polymeric materials may be used to fabricate some or all of the parts of the buckle 100. In some cases, the parts of the buckle 100 may be made from metals that are cast and/or machined. In other cases, parts of the buckle 100 may be fabricated from Acrylonitrile Butadiene Styrene (ABS), Polylactic Acid (PLA), Nylon, High density Polyethylene (HDPE), Polyoxymethylene (POM), Thermoplastic Rubber (TPR), Polypropylene (PP), High Impact Polystyrene (HIPS), other thermoplastics, combinations thereof, or the like. When using thermoplastics, compression molding, injections molding, and/or 3D printing may be used to fabricate the parts of the buckle 100. In some cases, the fasteners used for the joints 110, 112, 116 may be constructed from a different material than the other parts of the buckle 100.
In one example, the magnet 400 may be integrated within the wedge 102. For example, the magnet 400 may be placed within the wedge 102 in one or more cavities formed within the wedge 102. A ferroelectric material (e.g., a piece of steel or iron) or another magnet may be disposed on or in the lever 104 to selectively magnetically couple with the magnet 400 embedded within the wedge 102. This selective coupling, such as when the buckle 100 is in the closed position, allows for enhanced security in keeping the buckle latched and preventing undesired unlatching. In still other cases, the magnet 400 may be disposed inside the buckle 100 and a reciprocal ferromagnetic and/or magnet element may be disposed in or on the wedge 102. The magnet 400 may be of any suitable type, geometry, and/or strength. The magnet 400 may be of the type of neodymium, samarium cobalt, alnico, combinations thereof, or the like.
It should be understood that weightlifting belts come in different configurations (e.g., length, width, thickness, hole configuration, hole spacing, material types, etc.) and the disclosure herein contemplates minor variations in the buckle 100 to accommodate different types of weightlifting belts. It should also be understood that the improvements in the buckle 100, as disclosed herein, provide for a more perfect fit of the weightlifting belt on a person's torso. The fit of the weightlifting belt, in light of the technological and design advances disclosed herein, is not limited to the spacing of the holes in the weightlifting belt. Rather, the fit of the weightlifting belt can be modified using the fine adjustments on the buckle 100 (e.g., the worm screw 300).

In some cases, the lever 104 may be made from metals that are cast and/or machined. Due to the robust and sleek design of the buckle 100, a variety of lower-cost polymeric materials may be used to fabricate the lever 104. In some cases, the lever 104 may be fabricated from ABS, PLA, Nylon, HDPE, POM, TPR, PP, HIPS, other thermoplastics, combinations thereof, or the like. When using thermoplastics, compression molding, injections molding, and/or 3D printing may be used to fabricate the lever 104.

When using thermoplastics, compression molding, injections molding, and/or 3D printing may be used to fabricate the car 124.
At block 708, the worm screw 300 of the buckle 100 is formed. Although shown with a certain shape and size, it will be understood that the worm screw 300 may be fabricated with any suitable size, shape, thread pitch, thread density, thread shape, and/or thread protrusion. The worm screw 300 may be fabricated from any suitable material, such as any variety of metals (e.g., aluminum, stainless steel, steel, etc.), ceramics, polymers, and/or composite materials.

At block 712, the body 106 of the buckle 100 is formed. Although shown with a certain shape and size, it will be understood that the body 106 may be fabricated with any suitable size, shape, thread pitch, thread density, thread shape, and/or thread protrusion. The body 106 may have threads 302 formed therein to mesh with the threads of the worm screw 300. The threads 302 of the body 106 may be of any suitable type, corresponding to the threads of the worm screw 300. The body 106 may be fabricated from any suitable material, such as any variety of metals (e.g., aluminum, stainless steel, steel, etc.), ceramics, polymers, and/or composite materials. In some cases, the body 106 may be made from metals that are cast and/or machined.

At block 714, the car 124 is assembled onto the body 106 via the worm screw 300. The car may move along the rail 126 of the body 106. The worm screw 300 may be disposed between the car and the body, such that the thread of the worm screw mesh with threads on one or both of the body 106 and/or the car 124.
At block 716, the side elements 108 are assembled onto the body 106. In other words, the joints 116 are formed. In some cases, the fasteners used for the joints 110, 112, 116 may be constructed from a different material than the other parts of the buckle 100.
At block 718, the lever 104 is assembled onto the wedge 102 and the side elements 108. Thus, the joints 110, 116 are formed. In some cases, the fasteners used for the joints 110, 112, 116 may be constructed from a different material than the other parts of the buckle 100.
In some cases, the buckle 100 may be formed primarily with plastic-like materials. In these cases, epoxies, paints, or other finished may be disposed on the buckle after formation. In other cases, the buckle 100 may be formed primarily from metal, where in some cases, a finish or coating may be provided on the metal surfaces of the buckle 100. For example, a coating may be provided for the purposes of reducing corrosion or oxidation of the surfaces of the buckle 100. Other coatings may be used to prevent or reduce the appearance of fingerprints or other oils, dirt, or grime on the surfaces of the buckle 100. Any suitable process may be used to provide the coating on the surfaces of the buckle, such as physical vapor deposition (PVD), chemical vapor deposition (CVD), dip coating, sol-gel coating, electroplating, electroless plating, or the like.
It should be noted that some of the operations of method 700 may be performed out of the order presented, with additional elements, and/or without some elements. Some of the operations of method 700 may further take place substantially concurrently and, therefore, may conclude in an order different from the order of operations shown above.
The wedge 800 may further have one or more springs 816 disposed within cavities defined by edges 818 within the body element 802. These springs 816 may positionally bias the abutment element 804 relative to the body element 802. Due to the springs 816, the abutment element 804 may be pushed in or pull out relative to the body element 802 from a quiescent point of the springs 816. In this way, during the latching process, the spring-biased abutment element 804 allows for a small change in the overall dimensions of the wedge 800. Due to this allowed dimensional change during the latching process, a snug or tight latch may be achieved, where the lever 104 does not unbuckle easily when latched. Put another way, the abutment element 804 may be pushed into the body element 802 during the latching process to allow for an overall longer length of the wedge 800, rather than a shorter length of the wedge 800, to be latched. The longer length of the wedge 800, relative to the case where the abutment element 804 is not present, provides a more snug fit of the wedge 800 to the body 106 and the lever 102, when latched. The snug fit allows for a more secure and reliable latching as compared to a less snug fit of the wedge 800.
It should be understood that the abutment element 804 spring-biased action may be achieved in other ways. For example, the springs may be in different positions or various other types of springs may be used. In other cases, other spring like materials may be used to provide dimensional variability to the wedge 800, such as a block of rubber or other compressible material.
A latch element 918 may be slidably disposed within the slot 906 of the lever 902. In some cases, the latch element 918 may include and/or be constructed of a ferroelectric and/or magnetic material (e.g., iron, nickel, cobalt, chromium, etc.). During the action of latching the lever 902 to the wedge 904, the latch element 918 may slide within the slot 906, according to the edge of the wedge 904. When the buckle 100 is buckled, having the lever 902 buckled to the wedge 904, the latch element 918 is slidably disposed in both the slot 906 of the lever 902 and the cavity 910 of the wedge 904. In this condition, the latch element 918 may be attracted to the magnet 916 by way of magnetic attractive force, causing the latch element 918 to move to a latched position, providing a barrier to unlatching the lever 902 from the wedge 904. Thus, during exercise, the latch element 918 magnetically held against edges 912 at a point within the cavity 910 that is most proximal to the magnet 916 prevents movements in the wearer's torso from accidentally unlatching the lever 902 from the wedge 904. When the wearer wishes to unbuckle the buckle 100, the wearer may slide the latch element 918 away from the magnet 916, against the force of the magnet 916, to a position that allows the wearer to unlatch the lever 902 from the wedge 904.
