Modes for Carrying Out the Invention

[0021] Hereinafter, a plurality of embodiments according to the present disclosure will be described with reference to the accompanying drawings. For the sake of clear description, many implementation details are also described below, but the present disclosure is not limited by these details. That is, in some embodiments of the present disclosure, these details are not essential. In addition, in order to simplify the drawings, well-known components and members may be represented by simplified schematic illustrations.

[0022] One embodiment of the present disclosure provides a squat depth gauge that assists a user in performing accurate squat training and can adjust the squat depth according to an individual's physique and type of training. In addition, each member of the squat depth gauge has a detachable design, and is excellent in storage and portability.

[0023] Referring to FIG. 1, a usage example of a squat depth gauge according to an embodiment of the present disclosure is shown. The squat depth gauge 100 can be installed corresponding to any type of squat equipment 10 (so-called squat rack), and is configured such that when the user performs a squat motion, the user can easily and surely recognize whether his / her squat depth has reached the set target depth. Thereby, the user can perform accurate squat training.

[0024] In some embodiments, the squat depth gauge 100 includes a bottom support frame 200, a scale pole 300 provided upright on the bottom support frame 200, and an indicating member 400 movably disposed on the scale pole 300. The width of the bottom support frame 200 can be adjusted according to the width of the squat equipment 10 to be used, and is set so that the width of the bottom support frame 200 substantially matches the width of the squat equipment 10. In addition, the length of the bottom support frame 200 is adjusted according to the physique of the user, whereby the position of the indicating member 400 is set to substantially match the position under the user's buttocks during squatting. In some embodiments, the bottom support frame 200 may be installed in contact with the squat equipment 10 or may be installed non-contact.

[0025] The scale pole 300 has multiple markings, and the indicator member 400 is movably positioned on the scale pole 300. This allows the indicator member 400 to be set to a predetermined height on the scale pole 300 according to the user's needs, and the distance (spacing) d between the indicator member 400 and the ground is set. This distance d is used as the depth target during the squat movement.

[0026] After setting the squat depth gauge 100, the user can easily determine whether their squat depth has reached a pre-set target depth by checking whether their buttocks make contact with the indicator member 400 during the squat movement. This enables the user to perform accurate squat training. In some embodiments, the indicator member 400 is made of an elastic material, which expands the acceptable range of contact between the user and the indicator member 400, and reduces discomfort caused by a rigid indicator member 400, as well as the risk of the user falling due to excessive weight being placed on the indicator member 400.

[0027] Referring to Figure 2, an exploded view of a squat depth gauge according to one embodiment of the present disclosure is shown. The squat depth gauge 100 comprises a bottom support frame 200, a scale pole 300 mounted upright on the bottom support frame 200, and a movably positioned indicator member 400 on the scale pole 300. In some embodiments, the bottom support frame 200 comprises a first pole 210, two second poles 220, two L-shaped adapters 230, and two engaging pieces 240. The second poles 220 are assembled to both ends of the first pole 210 via the L-shaped adapters 230, and both ends of the first pole 210 are assembled to the L-shaped adapters 230 via the engaging pieces 240. Furthermore, the design of the engaging pieces 240 can improve the structural strength of the bottom support frame 200.

[0028] For example, the first pole 210 comprises at least one first sliding member 212 and a second sliding member 214. The first sliding member 212 is slidable relative to the second sliding member 214, thereby allowing adjustment of the length of the first pole 210, for example, the length along the first direction D1 corresponding to the width of the squat machine 10 shown in Figure 1. In some embodiments, the first sliding member 212 and the second sliding member 214 are arranged coaxially, and the first sliding member 212 has a large inner diameter capable of accommodating the second sliding member 214. In other embodiments, the first sliding member 212 and the second sliding member 214 may be arranged in parallel and slidably relative to each other, for example, by a slide rail structure.

[0029] At least one first slide member 212 is provided with a lateral scale S1, and a plurality of positioning holes 216 are provided at positions corresponding to these lateral scales S1. For example, positioning holes 216 corresponding to 90cm, 95cm, 100cm, 105cm, 110cm, 115cm, and 120cm are formed. The user can position the second slide member 214 relative to the first slide member 212 by inserting a positioning member 218, such as a pin, screw, or spring ball, into the selected positioning hole 216, thereby making the positioning member 218 function as a stopper. This allows the length of the first pole 210 to be matched to the width of the squat machine 10 shown in Figure 1.

[0030] For example, the second pole 220 comprises at least one third sliding member 222 and a fourth sliding member 224, the third sliding member 222 being slidable relative to the fourth sliding member 224, thereby allowing adjustment of the length of the second pole 220, i.e., the length along the second direction D2 corresponding to the distance between the user and the squat equipment 10 shown in Figure 1. In some embodiments, the third sliding member 222 and the fourth sliding member 224 are arranged coaxially, and the third sliding member 222 has a larger inner diameter to accommodate the fourth sliding member 224 inside. In other embodiments, the third sliding member 222 and the fourth sliding member 224 are arranged in parallel and may be slidably provided relative to each other, for example, by a slide rail structure.

[0031] At least one third slide member 222 is provided with a vertical scale S2, and a plurality of positioning holes 226 are formed at positions corresponding to these vertical scales S2. For example, positioning holes 226 corresponding to 60cm, 75cm, and 90cm are provided. The user can position the fourth slide member 224 relative to the third slide member 222 by inserting a positioning member 228, such as a pin, screw, or spring ball, into the selected positioning hole 226, thereby causing the positioning member 228 to function as a stopper. This makes it possible to adjust the length of the second pole 220. Note that the required adjustment amount will differ depending on the user's physique and exercise habits, so the interval between the vertical scales S2 on the second pole 220 may be set to be larger than the horizontal scale S1 on the first pole 210.

[0032] For example, the L-shaped adapter 230 is equipped with two elastic arms 232, and when the second pole 220 is assembled to the L-shaped adapter 230, the elastic arms 232 are configured to clamp the third slide member 222. In some embodiments, the elastic arms 232 and the third slide member 222 are provided with locking holes 235 and 225, respectively, and the user can fix the second pole 220 and the L-shaped adapter 230 by inserting a locking member 250 such as a screw into these locking holes 235 and 225. In other embodiments, the second pole 220 and the L-shaped adapter 230 may be engaged by a latch mechanism or a spring ball mechanism.

[0033] For example, the engaging piece 240 is formed in the shape of a right triangle, and engaging claws 242 are provided on both side edges of the engaging piece 240. The L-shaped adapter 230 is provided with engaging grooves 234 corresponding to the engaging claws 242, and the first sliding member 212 of the first pole 210 is also provided with engaging grooves 215 corresponding to the engaging claws 242. The user can assemble the first pole 210 and the L-shaped adapter 230 without using tools by engaging the engaging claws 242 of the engaging piece 240 with the engaging grooves 234 of the L-shaped adapter 230 and the engaging grooves 215 of the first sliding member 212 while the first pole 210 is in contact with the L-shaped adapter 230.

[0034] Furthermore, because the engaging piece 240 is in the shape of a right triangle, after the assembly of the bottom support frame 200 is complete, both side edges of the engaging piece 240 come into contact with the first pole 210 and the L-shaped adapter 230, respectively. This not only increases the structural strength of the squat depth gauge 100, but also prevents the L-shaped adapter 230 and the scale pole 300 from tilting relative to the first pole 210, especially when the user's buttocks come into contact with the support member 400 and a downward load is applied.

[0035] For example, the support member 400 comprises an elastic rope 410 and hooks 420 provided at both ends of the elastic rope 410. Because the elastic rope 410 has the property of being stretchable, it can adapt to changes in the length of the first pole 210 (changes in the width of the squat equipment 10), and slack or excessive tension is less likely to occur. The elastic support member 400 expands the permissible range of contact between the user and the support member 400, and reduces discomfort caused by a rigid support member and the risk of the user falling over by putting excessive weight on the support member 400. In some embodiments, the support member 400 is fixed by engaging the hooks 420 at both ends of the elastic rope 410 with holes 315 in the scale pole 300. In other embodiments, the hooks 420 are made of a magnetic material, and by providing a magnet on the scale pole 300, the hooks 420 can be attracted to the scale pole 300 by magnetic force and positioned. In yet another embodiment, the support member 400 is not limited to an elastic rope, but may be composed of, for example, a horizontal bar, as long as it can be movably positioned on the scale pole 300.

[0036] For example, the scale pole 300 comprises a basic scale member 310 and an additional scale member 320. The L-shaped adapter 230 has a sleeve 236, and the extension direction of the sleeve 236 is perpendicular to the extension direction of the elastic arm 232. The basic scale member 310 and the sleeve 236 are provided with corresponding locking holes 316 and 238, respectively. The user can assemble the basic scale member 310 to the L-shaped adapter 230 by inserting a locking member 250, such as a screw, into the locking holes 316 and 238 of the basic scale member 310 and the sleeve 236. In other embodiments, the scale pole 300 and the L-shaped adapter 230 may be engaged by a latch mechanism, a spring ball mechanism, or the like.

[0037] Referring to Figures 2 and 3, Figure 3 is a schematic diagram showing different elevations of a scale pole 300 according to one embodiment of the present disclosure. At least one elevation of the basic scale member 310, for example, the first elevation 311, is provided with a vertical scale S3, which is set to increase from bottom to top. That is, the vertical scale S3 represents the height from the ground (height along the third direction D3 shown in Figure 1). The other elevation of the basic scale member 310, for example, the second elevation 312, is provided with a plurality of holes 315 corresponding to the vertical scale S3, and the hook 420 of the indicator member 400 engages with these holes 315. In some embodiments, the first elevation 311 may be positioned adjacent to the second elevation 312, and in other embodiments, the first elevation 311 may be positioned opposite the second elevation 312.

[0038] The additional scale member 320 is selectively assembled to the basic scale member 310. For example, the additional scale member 320 is engaged with the basic scale member 310 by a latch mechanism, a spring ball mechanism, or the like. The additional scale member 320 has a vertical scale S3' (see Figure 4A) and a plurality of holes 325 corresponding to the vertical scale S3', and the range of the vertical scale S3' of the additional scale member 320 is different from the range of the vertical scale S3 of the basic scale member 310. More specifically, the vertical scale S3' of the additional scale member 320 has a range that continues continuously from the vertical scale S3 of the basic scale member 310, so that the scale of the scale pole 300 increases continuously from bottom to top.

[0039] If the user's squat depth is low and within the range of the vertical scale S3 of the basic scale member 310 is sufficient, then only the vertical scale S3 of the basic scale member 310 needs to be referenced. On the other hand, if the user's squat depth is high and exceeds the range of the vertical scale S3 of the basic scale member 310, then the additional scale member 320 can be attached to the basic scale member 310, and the vertical scale S3' of the additional scale member 320 can be referenced for use.

[0040] In some embodiments, the squat depth gauge 100 further includes a weight block 260 provided within the bottom support frame 200. At least one weight block 260 is provided and is installed on the first pole 210 and / or two second poles 220. In some embodiments, two weight blocks 260 are provided, each positioned at the ends of the two second poles 220, i.e., the ends furthest from the L-shaped adapter 230. In other embodiments, the weight block 260 may be located in the middle of the first pole 210 and / or the two second poles 220, for example, on the second slide member 214 and / or the fourth slide member 224. In this case, the weight block 260 can be performed by forming the second slide member 214 and / or the fourth slide member 224 as a solid structure.

[0041] The weight block 260 can improve the installation stability of the bottom support frame 200 by increasing the downward load between the bottom support frame 200 and the ground. It also has the effect of preventing the support member 400 and the scale pole 300 from tipping over due to a shift in the center of gravity, especially when the user's buttocks come into contact with the support member 400 and a downward load is applied to the squat depth gauge 100 during exercise.

[0042] Referring to Figures 4A and 4B, different disassembled stages of a squat depth gauge according to one embodiment of the present disclosure are shown. Since the first pole 210 and the two second poles 220 of the bottom support frame 200 are each configured to be retractable, when the squat depth gauge 100 is not in use, the user can shorten the first pole 210 and the two second poles 220, respectively, thereby effectively reducing the space occupied by the squat depth gauge 100 and making it easy to store and carry.

[0043] Furthermore, if the squat depth gauge 100 needs to be stored or carried, the user can detach the first pole 210 from the L-shaped adapter 230 simply by pulling out the engaging piece 240 (see Figure 4A). At this time, the second pole 220 and the scale pole 300 remain attached to the L-shaped adapter 230, and the scale pole 300 can be positioned parallel to the second pole 220 by changing the connection angle between the L-shaped adapter 230 and the second pole 220, for example by rotating the elastic arm 232 of the L-shaped adapter 230 relative to the second pole 220 (see Figure 4B). This significantly reduces the space required for the squat depth gauge 100, making it easier to store and carry.

[0044] Referring to Figure 5, an exploded view of a squat depth gauge according to another embodiment of the present disclosure is shown. In the other embodiment, the first sliding member 212 and the second sliding member 214 of the first pole 210 of the bottom support frame 200 may be configured to be separable. That is, when it is necessary to store the squat depth gauge 100, the squat depth gauge 100 can be divided into two main members 100A and 100B by pulling the second sliding member 214 out of the first sliding member 212, and these two main members 100A and 100B can be stored leaning against a wall corner or the like. This configuration effectively reduces the space occupied by the squat depth gauge 100.

[0045] In some embodiments, the squat depth gauge 100 shown in Figure 5 can be further foldable as shown in Figures 4A and 4B to enhance portability. In other embodiments, the L-shaped adapter 230, the first sliding member 212 on the first pole 210, the engaging piece 240, and the third sliding member 222 on the second pole 220 may be fixed by welding and integrally molded, thereby reducing manufacturing costs.

[0046] Referring to Figure 6, a three-dimensional view of a squat depth gauge according to yet another embodiment of this disclosure is shown. The desired squat depth varies depending on the user's training mode. For example, when a user performs a parallel squat, the ideal knee flexion angle is approximately 60 to 70 degrees. For a half squat, the ideal range is approximately 80 to 100 degrees, and for a quarter squat, it is approximately 110 to 140 degrees. In these squat types, the depth of a parallel squat is shallower than that of a half squat, and the depth of a half squat is shallower than that of a quarter squat.

[0047] As described above, the vertical scale S3 of the scale pole 300 indicates the height from the ground, increasing from bottom to top. To allow the user to intuitively select the desired squat depth and to reduce the effort of converting between squat depth and height from the ground, the squat depth gauge 100 may have height interval indicators 330 on the scale pole 300.

[0048] For example, the height interval indicator 330 includes, in order from bottom to top, a first height interval indicator 331, a second height interval indicator 332, and a third height interval indicator 333. The first height interval indicator 331 corresponds to a squat depth interval suitable for parallel squats, the second height interval indicator 332 corresponds to a squat depth interval suitable for half squats, and the third height interval indicator 333 corresponds to a squat depth interval suitable for quarter squats.

[0049] In some embodiments, clear visual differences can be provided between the first height interval indicator 331, the second height interval indicator 332, and the third height interval indicator 333. This allows the user to intuitively select the desired squat depth. For example, the first height interval indicator 331, the second height interval indicator 332, and the third height interval indicator 333 may be distinguished by using different colors, thick dividing lines, washer (ring) marks, or other methods.

[0050] This disclosure provides an individually adjustable squat depth gauge. This squat depth gauge allows users to easily determine whether they have reached a pre-set depth target by observing whether their buttocks contact a guide during the squat movement, enabling accurate squat training. Furthermore, this squat depth gauge is applicable to various types of squat equipment and can be used without modifying the structure of the squat equipment itself, thus improving practicality. In addition, the squat depth gauge can be disassembled into multiple parts, effectively reducing the space it occupies, making it excellent for storage and portability.

[0051] Although this disclosure has been described based on the embodiments described above, it is not intended to limit this disclosure to these embodiments. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure. Accordingly, the scope of protection of this disclosure shall be defined by the claims set forth below. [Explanation of Symbols]
