Abstract
Description
Technical Field
[0001] This invention relates to the field of fitness equipment technology, specifically to a curved arm grip mounted on a squat rack. Background Technology
[0002] A squat rack is an essential multi-functional exercise equipment for gyms or home workouts. With the addition of accessories, it can be used for storage, squats, bench presses, pull-ups, dips, and more.
[0003] Dips are divided into narrow-grip dips and wide-grip dips. A narrow grip means the distance between the bars is the same as shoulder width, while a wide grip means the distance between the bars is wider than shoulder width. A narrow grip works the triceps and posterior deltoids, while a wide grip works the pectoralis major. Dips can be performed on parallel bars or a squat rack with bent-arm handles.
[0004] The existing flexor arm grip includes a pin (inserted into a pin hole in the upright column during use), a U-shaped body (a three-sided encircling structure consisting of a central main plate and two side plates) that works with the pin to restrict its rotation in a certain direction, and a grip that is fixedly connected to the U-shaped body. When installed on a squat rack, it adds a flexor arm exercise function to the squat rack.
[0005] Existing flexor grips come in various forms, but generally have the following drawbacks: 1. Most are single-grip designs, with two flexor grips combined and installed on a squat rack. Due to the one-piece design (welded or bolted), the spacing between the two grips is not adjustable. Even with a double-grip design, there are only four grips on the same plane after combination, resulting in only three sets of spacing when paired. Given the different body types of users, and the distinction between wide and narrow grips, the applicability or versatility of existing flexor grips is not high, making it difficult to accurately target specific muscle groups. 2. The pin holes on the squat rack uprights are mostly oriented forward and backward. Most existing flexor grips can only be installed on the front of the squat rack, and a few can only be installed on the side. For some users, purchasing a set (two) of flexor grips means they want to install them not only on the front or side, but also on both sides. However, existing flexor grips do not meet the requirements for flexible installation, limiting the freedom of installation. 3. Due to the inconsistent hole diameters, existing curved arm grips are incompatible with standard designs. (If the pin diameter is larger than the hole diameter, the pin cannot be inserted; if the pin diameter is smaller than the hole diameter, the grip will sag. The greater the difference in diameter between the pin and the hole, the greater the sag.) There are dozens of different squat racks on the market. Manufacturing a matching curved arm grip for each rack would be extremely costly. Therefore, there is an urgent need for a curved arm grip that can be selectively installed on the front and sides of a squat rack, with adjustable spacing to accommodate different user body types and grip width requirements, and compatible with different squat racks (pin holes on the uprights). Summary of the Invention
[0006] Therefore, embodiments of the present invention provide a curved arm grip that can be installed on a squat rack to solve one or more of the technical problems of existing curved arm grips, such as the inability to choose whether to install them on the front or side of the squat rack, the inability to adjust the spacing, and the inability to be used with different squat racks.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A first aspect of the present invention provides a curved arm grip for mounting on a squat rack, comprising a U-shaped body, a plate-shaped pin, a cylindrical pin, a support tube, a sliding sleeve, and a grip; the body includes a main plate and side plates located on both sides of the main plate; each of the two side plates has a side pin hole in its middle section, and the two side pin holes are coaxial; the plate-shaped pin is detachably fixed to the end of the two side plates away from the main plate; the main plate and the plate-shaped pin are respectively provided with a positive pin hole, and when the plate-shaped pin is fixed to the side plate, the two positive pin holes are coaxial; the cylindrical pin can pass through the two side pin holes or the two positive pin holes; the support tube is fixed to the side of the main plate away from the U-shaped groove; the sliding sleeve is slidably disposed on the support tube, and the sliding sleeve cannot rotate around the support tube; the grip is arranged laterally, with one end fixed to the sliding sleeve and the other end away from the support tube and the sliding sleeve.
[0009] Furthermore, the support tube is a square tube, and the sliding sleeve is a U-shaped sleeve adapted to the square tube so that the sliding sleeve cannot rotate around the support tube.
[0010] Furthermore, the square tube is provided with multiple equally spaced limiting pin holes, and the U-shaped sleeve is provided with one or a pair of limiting pin holes. By inserting limiting pins through the limiting pin holes, the position of the U-shaped sleeve in the length direction of the square tube is relatively fixed.
[0011] Furthermore, the support tube is a round tube, and the sliding sleeve is a C-shaped sleeve or a semi-circular sleeve. The round tube is provided with multiple equally spaced limiting pin holes, and the C-shaped sleeve has one or a pair of limiting pin holes. By inserting limiting pins through the limiting pin holes, the position of the C-shaped sleeve in the length direction of the round tube is relatively fixed, and the C-shaped sleeve cannot rotate around the round tube.
[0012] Furthermore, each of the two side plates has a strip-shaped insertion hole at the end furthest from the main board. The strip-shaped insertion hole is arranged vertically, and the plate-shaped pin can be inserted into the two strip-shaped insertion holes.
[0013] Furthermore, the plate-shaped pin has a locking slot at the lower part of both ends, and when the plate-shaped pin is inserted into the strip-shaped insertion hole, the locking slot locks the lower edge of the strip-shaped insertion hole; or, one end of the plate-shaped pin has a through hole for passing a pin, and the size of the other end is larger than the size of the strip-shaped insertion hole; or, both ends of the plate-shaped pin have through holes for passing a pin.
[0014] Furthermore, both ends of the cylindrical pin are provided with through holes for threading pins; or, one end of the cylindrical pin is provided with a spring bead, the other end is larger than the size of the side pin hole and the front pin hole, and a pull ring is provided at the large end of the cylindrical pin.
[0015] Furthermore, the end of the support tube away from the main board is provided with an end plate, the upper end of which protrudes above the upper plane of the support tube to form a retaining edge.
[0016] Furthermore, the inner sides of both the motherboard and the side panel are provided with anti-scratch pads.
[0017] A second aspect of the invention provides another curved arm grip mounted on a squat rack, comprising a U-shaped body, the body including a main plate and side plates located on both sides of the main plate, the curved arm grip further including a plate-shaped pin, a cylindrical pin, a support tube, and a grip; both side plates have side pin holes in their middle sections, the two side pin holes being coaxial; the plate-shaped pin is detachably fixed to the end of the two side plates away from the main plate; the main plate and the plate-shaped pin are respectively provided with positive pin holes, the two positive pin holes being coaxial when the plate-shaped pin is fixed to the side plate; the cylindrical pin can pass through the two side pin holes or the two positive pin holes; the support tube is fixed to the side of the main plate away from the U-shaped groove, the support tube having multiple horizontally oriented insertion holes, the multiple insertion holes being equally spaced along the length direction of the support tube; the grip is arranged laterally, one end inserted into the insertion hole, the other end away from the support tube.
[0018] The embodiments of the present invention have the following advantages:
[0019] The curved arm grip provided by this invention, when installed on a squat rack, has its U-shaped groove facing the upright. After the main body is attached to the upright, a plate-shaped pin is installed to form a U-shaped structure. The inner side of the U-shaped structure is almost in contact with the outer side of the square upright (achieved through the design of relevant dimensions), thereby preventing the support tube from sagging (mainly the plate-shaped pin and the main body play the role of preventing sagging). Then, a cylindrical pin is inserted into the front pin hole or the side pin hole, and at the same time, the cylindrical pin passes through the pin hole of the upright (the size of the cylindrical pin is smaller than the size of the smallest pin hole of the upright on the market), thus achieving the height limit of the curved arm grip. There are two installation methods. One method involves the U-shaped groove facing left and right of the column. In this case, the axes of the two side pin holes are along the front-back direction. Since the axis of the column pin holes is also along the front-back direction, the cylindrical pin is inserted into the two side pin holes in this installation method. The other method involves the U-shaped groove facing front and back of the column. In this case, the axes of the two main pin holes are also along the front-back direction. Since the axis of the column pin holes is also along the front-back direction, the cylindrical pin is inserted into the two main pin holes in this installation method. When using the device, grip the handles with both hands to perform parallel bar dips. Because the sliding sleeve can slide along the support tube but cannot rotate, the grip spacing of the two curved arm handles mounted on the two columns is adjustable, thus accommodating users of different body types and meeting the training needs of both wide and narrow grips.

[0029] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example 1
[0031] like Figures 1 to 6 As shown, Embodiment 1 provides a curved arm grip installed on a squat rack, including a main body, a plate-shaped pin 3, a cylindrical pin 4, a support tube 5, a sliding sleeve 6, and a grip 7.
[0032] The main body is similar to existing structures, U-shaped, including a main board 1 and side plates 2 on both sides of the main board 1. The main board 1 and side plates 2 can be formed by bending or stamping a single steel plate, or by welding three steel plates. The side of the main board 1 and side plates 2 facing the U-shaped groove is the inner side. Generally, anti-scratch pads are provided on the inner side of the main board 1 and side plates 2 to prevent scratching or damaging the paint on the upright. After installation on the squat rack, the inner side of the U-shaped groove, or the main board 1 and side plates 2, is almost in contact with three sides of the upright (when anti-scratch pads are provided, the anti-scratch pads are in contact with the surface of the upright). This prevents the support tube 5 from sagging after the plate-shaped pins 3 are installed. The main board 1 has a positive pin hole 9. The middle section of both side plates 2 has side pin holes 10, and the two side pin holes 10 are coaxial; the far end of both side plates 2 (the end away from the main board 1) has a vertically arranged strip-shaped insertion hole 11. The plate-shaped pin 3 can be inserted into the two strip-shaped holes 11, thereby detachably connecting to the two side plates 2; the plate-shaped pin 3 also has a positive pin hole 9, and when the plate-shaped pin 3 is fixed to the side plate 2, the positive pin hole 9 of the plate-shaped pin 3 and the positive pin hole 9 of the main plate 1 are coaxial. The cylindrical pin 4 can be inserted into the pair of side pin holes 10 or the pair of positive pin holes 9. The support tube 5 is fixed to the outside of the main plate 1. The sliding sleeve 6 is slidably disposed on the support tube 5, and the sliding sleeve 6 cannot rotate around the support tube 5. The handle 7 is arranged horizontally, with one end fixed to the sliding sleeve 6 and the other end away from the support tube 5 and the sliding sleeve 6.
[0033] The curved arm grip provided in this embodiment, when installed on a squat rack, has its U-shaped groove facing the upright. After the main board 1 is attached to the upright, a plate-shaped pin 3 is installed to form a U-shaped structure. The inner side of the U-shaped structure is almost in contact with the outer side of the square upright (achieved through the design of relevant dimensions), thereby preventing the support tube 5 from sagging (mainly due to the anti-sagging function of the plate-shaped pin 3 and the main board 1). Then, a cylindrical pin 4 is inserted into the front pin hole 9 or the side pin hole 10. At the same time, the cylindrical pin 4 passes through the pin hole of the upright (the size of the cylindrical pin 4 is smaller than the smallest pin hole size of the upright on the market), thus achieving the height limit of the curved arm grip. There are two installation methods. One is with the U-shaped groove facing the left and right sides of the column. In this case, the axes of the two side pin holes 10 are along the front-back direction. Since the axis of the column pin holes is along the front-back direction, in this installation method, the cylindrical pin 4 is inserted into the two side pin holes 10. The other is with the U-shaped groove facing the front-back direction of the column. In this case, the axes of the two main pin holes 9 are along the front-back direction. Since the axis of the column pin holes is along the front-back direction, in this installation method, the cylindrical pin 4 is inserted into the two main pin holes 9. During use, gripping the handles 7 with both hands allows for parallel bar dips. Because the sliding sleeve 6 can slide along the support tube 5 but cannot rotate, the spacing between the two curved arm handles 7 installed on the two columns is adjustable, thus accommodating users of different body types and meeting the training needs of both wide and narrow grips.
[0034] like Figures 1 to 3As shown, in this embodiment, the support tube 5 is a square tube, and the sliding sleeve 6 is a U-shaped sleeve adapted to the square tube, thereby ensuring that the sliding sleeve 6 cannot rotate around the support tube 5. The distance between the grips 7 of the two curved handles can be adjusted, and the adjustment distance is linear. Optionally, the square tube is provided with multiple equally spaced limiting pin holes, and the U-shaped sleeve has one or a pair of limiting pin holes. By inserting limiting pins through the limiting pin holes, the position of the U-shaped sleeve in the length direction of the square tube is relatively fixed. In this case, the adjustment distance between the two grips 7 is intermittent. Optionally, the support tube 5 is a round tube, and the sliding sleeve 6 is a C-shaped sleeve or a semi-circular sleeve. The round tube is provided with multiple equally spaced limiting pin holes, and the C-shaped sleeve has one or a pair of limiting pin holes. By inserting limiting pins through the limiting pin holes, the position of the C-shaped sleeve in the length direction of the round tube is relatively fixed, and the C-shaped sleeve cannot rotate around the round tube. In this case, the adjustment distance between the two grips 7 is intermittent.
[0035] In this embodiment, the plate-shaped pin 3 has a locking slot 12 at its lower ends. When the plate-shaped pin 3 is inserted into the strip-shaped insertion hole 11, the locking slot 12 locks the lower edge of the strip-shaped insertion hole 11. Alternatively, one end of the plate-shaped pin 3 has a through hole 13 for threading a pin, and the other end is larger than the size of the strip-shaped insertion hole 11. Alternatively, both ends of the plate-shaped pin 3 have through holes 13 for threading pins. These designs prevent the plate-shaped pin 3 from falling off.
[0036] In this embodiment, both ends of the cylindrical pin 4 are provided with through holes 13 for threading pins; or, one end of the cylindrical pin 4 is provided with a spring bead, and the size of the other end is larger than the size of the side pin hole 10 and the front pin hole 9, and a pull ring is provided at the larger end of the cylindrical pin 4. These designs prevent the cylindrical pin 4 from falling off.
[0037] In this embodiment, an end plate 8 is provided at the end of the support tube 5 away from the main board 1, and the upper end of the end plate 8 is higher than the upper plane of the support tube 5 to form a stop. After removing the sliding sleeve 6 from the support tube 5 (and the grip 7 as well), the barbell can be placed on the two support tubes 5 (at this time, the two support tubes 5 need to be installed parallel to the two columns), which can serve multiple purposes.
[0038] Example 2
[0039] Example 2 provides another type of curved arm grip installed on a squat rack, including a U-shaped main body. The main body includes a main plate and side plates located on both sides of the main plate. The curved arm grip also includes a plate-shaped pin, a cylindrical pin, a support tube, and a grip. Both side plates have side pin holes in their middle sections, and the two side pin holes are coaxial. The plate-shaped pin is detachably fixed to the end of the two side plates away from the main plate. The main plate and the plate-shaped pin are respectively provided with positive pin holes. When the plate-shaped pin is fixed to the side plate, the two positive pin holes are coaxial. The cylindrical pin can be inserted into the two side pin holes or the two positive pin holes. The support tube is fixed to the side of the main plate away from the U-shaped groove. The support tube has multiple horizontally oriented insertion holes, which are evenly distributed along the length of the support tube. The grip is arranged horizontally, with one end inserted into the insertion hole and the other end away from the support tube.
[0040] The curved arm grip provided in Example 2 is a simplified form of the curved arm grip provided in Example 1, and has all the advantages of Example 1, such as adjustable spacing (the adjustment spacing is intermittent), load-bearing barbell bar, non-sagging support tube, and good versatility.
[0041] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
