Chinese Patent CN204273324U provides a reflective weighted steel plate vest, where a shoulder connection part of the vest is designed integrally to prevent breakage. The correspondence between weighted parts and body parts varies for users with different body proportions. For example, when a tall user wears the vest, the weighted part is at the abdomen, whereas for a shorter user, the weighted part is at the waist. The lack of adjustability to accommodate different users' body conditions results in a suboptimal user experience for some users.

In some embodiments, as shown in FIGS. 1 and 2, the weighted vest includes a first vet body 100 and a second vet body 200. In some embodiments, the first vet body 100 may include two symmetrically arranged first shoulder straps 110, wherein a first adhesive element 111 (as shown in FIG. 2) may be provided along a length direction of a first side of each of the two first shoulder straps 110, and a connecting strap 112 may be separated from the first adhesive element 111 and may be provided at a position of each of the two first shoulder straps 110 where the first adhesive element 111 is located. The second vet body 200 may include two symmetrically arranged second shoulder straps 210, wherein a second adhesive element 211 (as shown in FIG. 5) may be provided along a length direction of one side of each of the two second shoulder straps 210, and a connecting buckle 212 may be provided on another side of each of the two second shoulder straps 210 at a position corresponding to the second adhesive element 211. In some embodiments, the first adhesive element 111 may be detachably attached to the second adhesive element 211, and the connecting strap 112 may be detachably connected to the connecting buckle 212. In some embodiments, a first weight pocket 120 may be provided on the first vet body 100, and a second weight pocket 220 may be provided on the second vet body 200. More descriptions of the first vet body 100, the second vet body 200, the first weight pocket 120, and the second weight pocket 220 may be found in the related descriptions below.

The first vet body 100 refers to a part of the weighted vest that is located on a front side of a user's body when the user wears the weighted vest. The second vet body 200 refers to a part of the weighted vest that is located on a back side of the user's body when the user wears the weighted vest. When the user wears the weighted vest, the first shoulder straps 110 and the second shoulder straps 210 are located on the shoulders. More descriptions of the first vet body 100 and the second vet body 200 may be found in the related descriptions below.

In some embodiments, the first adhesive element 111 and the second adhesive element 211 may be detachably attached using a hook-and-loop fastener. The first adhesive element 111 and the second adhesive element 211 may be provided with a plurality of looped soft fibers and a plurality of hooked hard fibers, respectively. When the first adhesive element 111 and the second adhesive element 211 are attached to each other, the plurality of looped soft fibers and the plurality of hooked hard fibers interlock to achieve a secure attachment between the first adhesive element 111 and the second adhesive element 211. The user may adjust adhesive positions of the first shoulder straps 110 and the second shoulder straps 210 based on the height and a usage need of the user, thereby changing an overlapping area of the first shoulder straps 110 and the second shoulder straps 210, so that hems of the first vet body 100 and the second vet body 200 are disposed appropriately for the user's body, ensuring comfortable wear. In some embodiments, the first adhesive element 111 and the second adhesive element 211 may be detachably attached using other structures, such as reusable glue.

In some embodiments, the connecting strap 112 and the connecting buckle 212 may be detachably connected. The connecting buckle 212 may be a buckle ring through which the connecting strap 112 is threaded (as shown in FIG. 1). The connecting strap 112 and the connecting buckle 212 may be detachably connected using other structures, such as a clasp, a snap button, a button, a side-release buckle, a safety pin, a tie, a hook, etc., which are not limited by the present disclosure. For example, if the connecting buckle 212 is a button, the connecting strap 112 may be provided with a plurality of buttonholes through which the button may be fastened. As another example, if the connecting buckle 212 is a main fastener, the connecting strap 112 may be provided with a plurality of auxiliary fasteners for press-fit attachment.

In some embodiments, the connecting strap 112 may be provided at the position of the first shoulder strap 110 where the first adhesive element 111 is located. One end of the connecting strap 112 may be fixedly connected to the first vet body 100, while the other end the connecting strap 112 may be a free end that aligns with but moves freely relative to the first adhesive element 111 (i.e., separated from the first adhesive element 111). Correspondingly, in some embodiments, the second vet body 200 may include two symmetrically arranged second shoulder straps 210 (as shown in FIG. 3 and FIG. 5). An inner side of each of the two second shoulder straps 210 may be provided with the second adhesive element 211 along a length direction of the second shoulder straps 210, and on an another side of each of the two second shoulder straps 210, the connecting buckle 212 may be provided at a position corresponding to the second adhesive element 211.

In some embodiments, after attaching the first adhesive element 111 to the second adhesive element 211, the user may further secure the first shoulder straps 110 and the second shoulder straps 210 by combining the connecting strap 112 with the connecting buckle 212. It should be noted that the second adhesive element 211 is provided on one side of the second shoulder straps 210, while the connecting buckle 212 is provided on another side of the second shoulder straps 210. Specifically, during installation, the second shoulder straps 210 may be disposed above the first shoulder straps 110. The connecting strap 112 on the first shoulder strap 110 combines with the connecting buckle 212 on top of the second shoulder straps 210 to form a clamping structure with the connecting strap 112 and a main body of the first shoulder straps 110 clamping a main body of the second shoulder straps 210 (i.e., the second shoulder strap 210 is in the middle, and two sides of the second shoulder strap are the connecting strap 112 and the first shoulder strap 110, respectively). In actual use, because the first vet body 100 and the second vet body 200 are quite heavy, an overlapping connection region of the first shoulder straps 110 and the second shoulder straps 210 creates a pressure on the user's shoulders. The pressure ensures that the connecting strap 112 and the first shoulder straps 110 are tightly affixed to two sides of the second shoulder straps 210, thereby increasing friction and preventing relative sliding between the first shoulder straps 110 and the second shoulder straps 210. Additionally, by increasing the friction, the connecting strap 112 is prevented from sliding within the connecting buckle 212, and by providing a dual fixation, stability of the combined first vet body 100 and second vet body 200 is ensured.

In some embodiments, to facilitate quick adjustments by the user based on the user's situation, an indicator mark may be provided on at least one of the two first shoulder straps 110 at a position corresponding to the first adhesive element 111. The indicator mark may be a marking line or a numerical mark created with a special coating or graphic, indicating an end position where the second shoulder strap 210 adheres to the first shoulder strap 110. For example, a manufacturer may set a same indicator mark (with a plurality of height marking lines) or different indicator marks (with only a corresponding height) on the weighted vest for users with different heights. The manufacturer may preset the indicator mark based on a position of the second shoulder straps 210 on the first shoulder straps 110, allowing users to adjust according to their heights, thereby achieving quick adjustment and fitting.

In some embodiments of the present disclosure, the first vet body 100 and the second vet body 200 are configured as detachable independent entities. The first shoulder straps 110 of the first vet body 100 are provided with the first adhesive element 111 and the connecting strap 112, while the second shoulder straps 210 of the second vet body 200 are provided with the second adhesive element 211 and the connecting buckle 212. This configuration allows users to freely adjust the position of the combined first vet body 100 and second vet body 200 according to their heights and ensuring reliability of the combination, thereby effectively improving comfort of using the weighted vest for different users and ensuring a better user experience.

In some embodiments, each of two sides of the first vet body 100 may be provided with a third adhesive element 132, an outer side of the first weight pocket 120 may be provided with a fourth adhesive element 121; each of two sides of the second vet body 200 may be provided with a connecting ring 231, and the third adhesive element 132 may pass through the connecting ring and may be detachably connected to the fourth adhesive element 121. Specifically, the third adhesive element 132 may pass through the connecting ring 231, fold back, and detachably connect to the fourth adhesive element 121. In some embodiments, the connecting ring 231 may be not required, and the third adhesive element 132 may wrap around the waist of the user and detachably connect to the fourth adhesive element 121. The third adhesive element 132 or the fourth adhesive element 121 may also be provided on the second vet body 200 without limitation. More descriptions of the detachable connection structure of the third adhesive element 132 and the fourth adhesive element 121 may refer to the detachable connection structure of the connecting strap 112 and the connecting buckle 212 above. Since relying only on the first shoulder straps 110 and the second shoulder straps 210 makes it difficult to securely attach the first vet body 100 and the second vet body 200 to the user's chest and back, it may not prevent the first vet body 100 and the second vet body 200 from shaking during movement. The detachable connection structure of the third adhesive element 132 and the fourth adhesive element 121 allows the first vet body 100 and the second vet body 200 to be securely attached to the user's chest and back.

In some embodiments, as shown in FIGS. 2 and 3, each of the two sides of the first vet body 100 may be provided with a first pad 130, the first pad 130 may be provided with a fixing strap 131. Correspondingly, each of the two sides of the second vet body 200 may be provided with a second pad 230, the connecting ring 231 may be provided on the second pad 230. During installation, the fixing strap 131 may pass through the connecting ring 231 to form a limiting structure. In some embodiments, the third adhesive element 132 may be provided on one side of the fixing strap 131 at a position corresponding to the first weight pocket 120. Correspondingly, the fourth adhesive element 121 may be provided on the outer side of the first weight pocket 120, and the third adhesive element 132 may be detachably connected to the fourth adhesive element 121. After the fixing strap 131 is limited by the connecting ring 231, fixation may be achieved through the detachable attachment of the third adhesive element 132 and the fourth adhesive element 121. The third adhesive element 132 and the fourth adhesive element 121 may also be configured as two parts of a hook-and-loop fastener to form a fixing attachment structure. In some embodiments, only the fixing strap 131 and the connecting ring 231 may be provided, or only the third adhesive element 132 and the fourth adhesive element 121 may be provided, which is not limited by the present disclosure.

In some embodiments, as shown in FIG. 1, after being connected by the first shoulder straps 110 and the second shoulder straps 210, the first vet body 100 and the second vet body 200 may be worn parallel to each other on the user's body. The fixing strap 131 may pass through the connecting ring 231 and wrap back to a corresponding position on the first vet body 100. At this point, the third adhesive element 132 on the fixing strap 131 may align with the fourth adhesive element 121 on the outer side of the first weight pocket 120. By applying a pressure, the first vet body 100 and the second vet body 200 may be securely attached to the user's body.

In some embodiments, there may be provided with two sets of fixing straps 131 which are arranged in parallel; alternatively, there may be provided with two sets of third adhesive elements 132 and fourth adhesive elements 121 which are arranged in parallel. When the two sets of fixing straps 131 are provided, one set may be disposed at a bottom of the first vet body 100 or a bottom of the second vet body 200 (near the user's waist or hips), and another set may be disposed at a position on the first vet body 100 or the second vet body 200 near the user's chest. When the two sets of third adhesive elements 132 and fourth adhesive elements 121 are provided, one set may be disposed at a bottom of the first vet body 100 or a bottom of the second vet body 200 (near the user's waist or hips), and another set may be disposed at a position on the first vet body 100 or the second vet body 200 near the user's chest. In some embodiments, one of the two sets of fixing straps 131 or one of two sets of third adhesive elements 132 and fourth adhesive elements 121 may be an elastic strap. The first vet body 100 and the second vet body 200 may be fixedly connected by the elastic strap (e.g., one end of the elastic strap is located on the first vet body 100, and another end of the elastic strap is located on the second vet body 200), or the first vet body 100 and the second vet body 200 may be detachably connected by the elastic strap (e.g., one end of the elastic strap is located on the first vet body 100, and another end of the elastic strap is detachably connected to the second vet body 200).

In some embodiments of the present disclosure, when using the weighted vest, adjustment and cooperation of the first shoulder straps 110 and the second shoulder straps 210 ensure that a hem position of the first vet body 100 and the second vet body 200 align with an optimal wearing position of the user. Then, through adjustment and cooperation of the fixing strap 131 and the connecting ring 231, the first vet body 100 and the second vet body 200 may be securely attached to the user's chest and back, which allows for customized fitting based on an actual situation of the user, ensuring that both the shoulders and waist match the body shape of the user, thereby enhancing wearing comfort.

In some embodiments, the first weight pocket 120 may be arranged at a position corresponding to the waist of the user, thereby avoiding pressure on the chest of the user. The first weight pocket 120 or the second weight pocket 220 may also be arranged at other positions according to different needs, such as on the shoulders (i.e., on the first shoulder straps or the second shoulder straps), on the chest, etc. In some embodiments, a size of the first weight pocket 120 may be the same as a size of the second weight pocket 220. At least one of an interior of the first weight pocket 120 or an interior of the second weight pocket 220 may be provided with a weight element, the weight element may be detachably connected to the first weight pocket 120 or the second weight pocket 220, and a shape of the weight element may be adapted to a shape of the first weight pocket 120 or a shape of the second weight pocket 220. In some embodiments, the weight element may be uniform in shape and may be freely placed in either the first weight pocket 120 or the second weight pocket 220. The user may determine a count of weight elements to place in the first weight pocket 120 and/or the second weight pocket 220 based on a fitness requirement. In some embodiments, the first weight pocket 120 and the second weight pocket 220 may be a whole body. In some embodiments, the first weight pocket 120 and the second weight pocket 220 may be divided into a plurality of sections (as shown in FIGS. 2 and 3, the first weight pocket 120 and the second weight pocket 220 include a plurality of weight pockets, respectively), each of the plurality of sections capable of holding weight element(s).

In some embodiments, the size of the first weight pocket 120 may differ from the size of the second weight pocket 220, and an area of the first vet body 100 may differ from an area of the second vet body 200. Using weight pockets of different sizes can better utilize space and expand a weight-carrying capacity of the weighted vet.

In some embodiments, as shown in FIGS. 2 and 3, an opening portion of the first weight pocket 120 may be provided with a first cover flap 122. One side of the first cover flap 122 may be fixedly connected to the first vet body 100, and another side of the first cover flap 122 may be a free end detachably attached to the outer side of the first weight pocket 120. An opening portion of the second weight pocket 220 may be provided with a second cover flap 221. One side of the second cover flap 221 may be fixedly connected to the second vet body 200, and another side of the second cover flap 221 may be a free end detachably attached to the outer side of the second weight pocket 220. The attachment structure of the first cover flap 122 and the second cover flap 221 may also be achieved using two parts of a hook-and-loop fastener. In actual use, the first cover flap 122 may be configured to limit the weight element(s) inside the first weight pocket 120, and the second cover flap 221 may be configured to limit the weight element(s) inside the second weight pocket 220, thereby preventing the weight elements from falling out due to a movement of the user. In some embodiments, the opening portion of the first weight pocket 120 or the opening portion of the second weight pocket 220 may not be provided with the first cover flap 122 or the second cover flap 221; instead, the opening portions may be configured to be elastic to achieve the same effect.

In some embodiments, the weight element may be made of a sandbag or a metal material (such as an iron plate, a steel plate, etc.). Weight elements with a same volume but different weights may be made using metals with different densities to meet load requirements of different users. In some embodiments, the weight element may also be made of an elastic material with a slow rebound property (such as a polyurethane material) combined with other high-density substances (such as lead powder, iron sand), thereby ensuring adequate weight while being deformable and resilient. The weight element may deform under a pressure caused by a movement (e.g., curling of the abdomen during a sit-up) of the user and return to its original shape when the pressure is released, which allows the weight element to adapt to a posture of the user and provides feedback on deformation of the first weight pocket 120 and/or the second weight pocket 220 during exercise, thus enhancing the user experience.

In some embodiments, the weight element may be a water pocket provided with a piston. The water pocket refers to a container that may be filled with or drained of water. The piston prevents water leakage. In some embodiments, the water pocket may be an ice water pocket or a hot water pocket. An inner side of a weight pocket (e.g., the first weight pocket 120 and/or the second weight pocket 220) may be provided with an insulating layer, keeping the water pocket warm or cold. When the water pocket is the ice water pocket (which may not require the piston), the ice water pocket may be placed inside the weight pocket (e.g., the first weight pocket 120 and/or the second weight pocket 220) and used for ice therapy or cooling after the user wears the weighted vest for exercise. The water pocket may also contain drinking water, allowing the user to drink and reduce weight after exercising.

FIG. 6 is an exemplary structural diagram of a limiting structure according to some embodiments of the present disclosure.

In some embodiments, as shown in FIG. 6, the first weight pocket 120 or the second weight pocket 220 may be provided with a limiting structure 150, which may be arranged perpendicular to the two first shoulder straps or the two second shoulder straps.

In some embodiments, the limiting structure 150 may include a limiting post configured to secure the weight element. The limiting post may include one or more long limiting posts 151 and one or more short limiting posts 152. The limiting structure 150 may further include one or more limiting elastic bands 153 and one or more limiting fixing bands 154. The one or more limiting fixing bands 154 may be arranged at two ends of the limiting structure 150 to fix the first weight pocket 120 or the second weight pocket 220, and the limiting elastic bands 153 may be arranged between the two limiting posts. When there is only one limiting post, there is no need to provide the limiting elastic bands 153. The one or more limiting fixing bands 154 may secure the limiting post to the first weight pocket 120 or the second weight pocket 220. The one or more limiting elastic bands 153 may tighten the limiting post, and after tightening, a pressure from the limiting post may secure the weight element. The limiting post may be a cylinder, and when the weight element is a sandbag, the limiting post may compress the sandbag to separate the sandbag vertically or horizontally. The one or more long limiting posts 151 may limit vertical movements, and the one or more short limiting posts 152 may limit horizontal movements. The limiting structure strengthens stability of the weight element and prevents the weight element from moving vertically or horizontally during exercise.

In some embodiments, the weight element may be a rechargeable battery. The rechargeable battery is a battery that may be recharged repeatedly. In some embodiments, the weight element may be a rechargeable battery, which may be used to increase the weight of the weighted vest, and the rechargeable battery may also be used in conjunction with other components. In some embodiments, the rechargeable battery may supply power for a physiological monitoring module, a vest state monitoring module, a communication module, or a processor (e.g., the rechargeable battery may supply power for the modules with a short charging cable).

In some embodiments, both the first vet body 100 and the second vet body 200 may be provided with one or more transverse fixing strips 124. The first weight pocket 120 or the second weight pocket 220 may be detachably connected to the one or more transverse fixing strips 124, or both the first weight pocket 120 and the second weight pocket 220 may be detachably connected to the one or more transverse fixing strips 124. Two ends of each of the one or more transverse fixing strips 124 may be fixed to the first vet body 100 or the second vet body 200, and the first weight pocket 120 or the second weight pocket 220 may be provided with a structure connected to the one or more transverse fixing strips 124 (e.g., through a detachable hook-and-loop fastener, a snap, a hook, or a bundled connection, as described above). A user may fix the first weight pocket 120 or the second weight pocket 220 at different positions on the one or more transverse fixing strips 124 as needed to balance a left side force and a right side force on the weighted vest or adjust left side force and the right side force according to requirements. In some embodiments, the two ends of each of the one or more transverse fixing strips 124 may be fixed to the fixing strap 131 or the second pad 230. After the fixing strap 131 is connected to the connecting ring 231, the one or more transverse fixing strips 124 may be tightened accordingly. Providing the one or more transverse fixing strips 124 on the first weight pocket 120 and/or the second weight pocket 220 ensures close fitting between the first and the second weight pockets and the body of the user, enhancing user experience. In some embodiments, lengths of the one or more transverse fixing strips 124 (FIG. 8 shows two transverse fixing strips 124) may be different. In some embodiments, a count of first weight pockets 120 or a count of second weight pockets 220 may be flexibly adjusted according to requirements.

In some embodiments, as shown in FIGS. 1 and 2, an end of the connecting strap 112 may be provided with an elastic sleeve 113, which may be made of an elastic band. The elastic sleeve is sewn onto the connecting strap 112 and configured in a ring shape. In some embodiments, the elastic sleeve 113 may be arranged on a side (e.g., a long side) of the end of the connecting strap 112, and a length of the elastic sleeve 113 (as shown in FIG. 2, a length direction of the elastic sleeve 113 is perpendicular to a length direction of the connecting strap 112) may match a width of the connecting strap 112. After the connecting strap 112 is wound along its length direction, the elastic sleeve 113 is sleeved on an outer side of the width direction of the connecting strap 112. The elastic sleeve 113 can enhance the stability of a combination of the connecting strap 112 and the connecting buckle 212, avoiding relative sliding between the connecting strap 112 and the connecting buckle 212 during a movement of the user. In actual use, after the connecting strap 112 and the connecting buckle 212 are combined at an appropriate position, the connecting strap 112 may be wound along an end, and the end of the wound connecting strap 112 may be pressed against an end of the connecting buckle 212, and then the elastic sleeve 113 may be sleeved and fixed to the end of the wound connecting strap 112. In this state, the elastic sleeve 113 may be used to limit a relative displacement between the connecting buckle 212 and the connecting strap 112, thereby fixing the position of the combination of the connecting strap 112 and the connecting buckle 212. In addition, by fixing the end of the wound connecting strap 112 with the elastic sleeve 113, swinging of an excess portion of the connecting strap 112 during user movement can be avoided, thus avoiding disturbing an action of the user.

In some embodiments, to align the first vet body 100 and the second vet body 200 when connected via the two first shoulder straps 110 and the two second shoulder straps 210, as shown in FIGS. 1 and 3, the second vet body 200 may be provided with a loop 213 at a position on a same side of the connecting buckle 212. The loop may have a structure similar to a structure used on pants to restrain belts. In actual setup, two ends of the loop 213 may be fixedly connected to the second shoulder straps 210, a center of the loop 213 may be separated from the second shoulder straps 210, and a size of the separation part may be matched (e.g., width-matched) with a size of the connecting strap 112. Before combining the connecting strap 112 with the connecting buckle 212, the connecting strap 112 may be threaded through the loop 213 to form a sheath structure on the connecting strap 112, and then the connecting strap 112 may be threaded into the connecting buckle 212 to form two sets of sheath structures. The symmetrically arranged first shoulder straps 110 and the second shoulder straps 210 may form two sets of cooperating structures, thus achieving alignment of the first vet body 100 and the second vet body 200.

In some embodiments, as shown in FIGS. 2 and 3, a first reflective strip 101 may be provided at a position corresponding to each of the two the first shoulder straps 110 on the first vet body 100, and a second reflective strip 201 may be provided at a position corresponding to each of the two the second shoulder straps 210 on the second vet body 200. When the user uses the weighted vest for exercise in a poor lighting condition, the first reflective strip 101 and the second reflective strip 201 can enhance safety. The first reflective strip 101 and the second reflective strip 201 may also be arranged at other positions, such as a bottom of the first vet body 100 and the second vet body 200 (e.g., a position near the waist or hips of the user after wearing the weighted vet). The first reflective strip 101 and the second reflective strip 201 may be made of a special optical coating material, capable of reflecting light sources. Therefore, when a vehicle passes by, the reflected light from the vehicle lights may help the driver notices the user wearing the weighted vest, ensuring the safety of the user during exercise.

In some embodiments, as shown in FIGS. 2 and 4, the zipper 140 may be provided on a symmetry axis of the first vet body 100, i.e., the zipper 140 may be provided at a position of the first vet body 100 corresponding to a vertical center position of the chest of the user, and a zipper pull 141 may be provided on the zipper 140. The zipper 140 may be unlocked or locked by moving the zipper pull 141, which allows a left part and a right part of the first vet body 100 to separate after unlocked. In actual use, after the user complete the adjustment of the first shoulder straps 110, the second shoulder straps 210, the fixing strap 131, and the connecting ring 231, the wearing and removing process may be directly completed by moving the zipper pull 141 to match the zipper 140, thereby eliminating the need of length adjustment by the user whenever the user wears the weighted vest. When the weighted vest is switched to another user, the weighted vest may be readjusted using the manner described in the above embodiments to adapt to different body shapes. The zipper 140 may also be replaced with a detachable structure described above, such as a hook-and-loop fastener, a button, a snap, etc.

In some embodiments, an interior of the first pad 130 and an interior of the second pad 230 may be filled with a flexible material to ensure the comfort of a contact region between sides of the first vet body 100 and the second vet body 200 and the user's body, avoiding pressure from the fixing strap 131 on the user.

In some embodiments, the interior of the first vet body 100 and the interior of the second vet body 200 may be provided with a filling layer made of a material with an elastic property, such as sponge or foam filling. By providing the filling layer, the first vet body 100 and the second vet body 200 can adapt to the user's body curves when worn, while avoiding pressure from heavy object(s) inside the first weight pocket 120 and the second weight pocket 220 on the user's body, thereby enhancing comfort.

In some embodiments, the first vet body and/or the second vet body, from inside to outside, include: a lining layer, a silicone layer, the filling layer, a deodorizing layer, and a breathable layer. In some embodiments, a material of the lining layer may be woolen fabric to increase contact comfort. A material of the silicone layer may be silicone, which may be disposed in region(s) prone to sliding, such as under the arms. A material of the deodorizing layer may be an activated carbon fiber material, capable of removing odors caused by exercise. A material of the breathable layer may be breathable mesh fabric. In some embodiments, the silicone layer and the deodorizing layer may be adhered together, with ventilation holes evenly distributed in the deodorizing layer to facilitate expulsion of more odors. The multi-layer design of the first vet body 100 or the second vet body 200 can eliminate sweat and odor generated during exercise, providing a comfortable wearing experience. Moreover, the combination of the silicone layer and the deodorizing layer can replace the PVE rebound rubber material commonly used in weighted vests, effectively reducing impact force while maintaining functionality of the multi-layer design without adding excessive weight to the weighted vest. In some embodiments, a position of the lining layer of the first vet body 100 or the second vet body 200 contacting with the user's body may be provided with an anti-slip strip, a silicone strip, or evenly distributed silicone particles, or the material of the lining layer may be anti-slip fabric to enhance an anti-slip effect.

In some embodiments, the first shoulder straps or the second shoulder straps may be provided with a fixing element. In some embodiments, both the first shoulder straps and the second shoulder straps may be provided with the fixing element. The weighted vest may also include a neck-hanging fan, which may be detachably connected to the fixing element. The structure of the detachable connection is as described above.

In some embodiments, the neck-hanging fan may be fixed to the first shoulder straps or the second shoulder straps (e.g., sewn onto the first shoulder straps or the second shoulder straps), or the neck-hanging fan may be fixed to both the first shoulder straps and the second shoulder straps simultaneously. The neck-hanging fan may be provided with a charging interface for charging, which may be provided on the neck-hanging fan or extended with wiring to the weight pocket. When the weight pocket is provided with the aforementioned battery, the battery may power or charge the neck-hanging fan. The neck-hanging fan may provide cooling when the user is overheated during exercise and help to remove sweat and odors, enhancing the overall experience.

In some embodiments, the weighted vest may be further provided with a storage mesh pocket. The storage mesh pocket may be placed at a convenient position such as on or next to the weight pocket. The storage mesh pocket may include an opening and a storage pocket. The storage pocket may have a relatively large size suitable for holding a water bottle or have a relatively small size suitable for holding keys; and the opening may be an elastic opening.

In some embodiments, a process of using the weighted vest may be as follows.

Firstly, the user may combine the connecting strap 112 on the first vet body 100 with the loop 213 and the connecting buckle 212 on the second vet body 200 to align the first vet body 100 and the second vet body 200.

Then, according to the user's height and marking lines on the two first shoulder straps 110, the user may place the end of each of the two second shoulder straps 210 corresponding to the marking lines on the two first shoulder straps 110, respectively, and secure them together using the first adhesive element 111 and the second adhesive element 211. Next, the user may adjust a length of the connecting strap 112 and a length of the connecting buckle 212 to match positions of the two first shoulder straps 110 and the two second shoulder straps 210, wrap the end of the connecting strap 112, and secures it with the elastic sleeve 113 to limit the connecting buckle 212, that is, the installation of the first shoulder straps 110 and the second shoulder straps 210 is completed.

The user may place the connected first shoulder straps 110 and second shoulder straps 210 on the shoulders, forming a wearing style with the first vet body 100 on the front chest and the second vet body 200 on the back. Then, the user may wrap the fixing strap 131 on the first pad 130 around the connecting ring 231 on the second pad 230, pull a free end of the fixing strap 131 to the first weight pocket 120 of the first vet body 100, and secure the free end of the fixing strap 131 by adhering the fixing strap 131 with the third adhesive element 132 and the fourth adhesive element 121.

The above process completes the first wearing of the weighted vest on the user's body. In subsequent wear and removal processes, the user may wear or remove the weighted vest by locking or unlocking the zipper 140 using the zipper pull 141 without the need for repeated adjustments. When the weighted vest is worn by a different user, the above process may be repeated to fit the vest to different body shapes.

During fitness activities, the user may freely replace the weighting element inside the first weight pocket 120 and/or the second weight pocket 220 to adapt to different fitness needs.

Some embodiments of the present disclosure provide fitness equipment, which includes the weighted vest described above.

In some embodiments, the weighted vest may include a physiological monitoring module and a vest state monitoring module. The physiological monitoring module and the vest state monitoring module may be in communication with a processor, respectively. The physiological monitoring module may be configured to collect physiological data, and the vest state monitoring module may be configured to collect vest data.

The physiological monitoring module refers to a device used to monitor a physiological feature of the user. The physiological monitoring module may include a heart rate sensor, a temperature sensor, a respiratory sensor, or the like. The physiological monitoring module may be provided on the first vet body 100 of the weighted vest near the chest, abdomen, or close to the heart.

The vest state monitoring module refers to a device used to monitor a state of the weighted vest. The vest state monitoring module may include a gyroscope, a pressure sensor, a position sensor, or the like. In some embodiments, the vest state monitoring module may include a gyroscope disposed at a bend of the first shoulder straps and the second shoulder straps, a pressure sensor disposed on an inner side of the first shoulder straps (i.e., a side in contact with the user's body), and two position sensors disposed on two sides of the fixing strap and at the waist positions of the first and second vet bodies.

The physiological monitoring module and the vest state monitoring module may be communicatively connected to the processor in various ways. For example, the physiological monitoring module and the vest state monitoring module may be provided with a communication module (e.g., Wi-Fi, Bluetooth, mobile communication, etc.) to establish communication with the processor.

The communication module may be configured to transmit the physiological data and the vest data to the processor and receive instructions from the processor. There may be various types of communication modules. In some embodiments, the communication module may be a Wi-Fi module installed on the weighted vest to connect to a wireless network. The weighted vest may transmit data to the processor (e.g., a remote server or a terminal server) via the Wi-Fi module and receive instructions from the processor. In some embodiments, the communication module may be a Bluetooth module installed on the weighted vest, allowing it to establish a connection with a smartphone or a smart wearable device (e.g., a smartwatch) where the processor is installed. The instructions may be sent to the weighted vest via an app installed on the smartphone. In some embodiments, the smartphone or the smart wearable device may receive the instructions from the processor (which may be a remote server) and then transmits the instructions to the weighted vest via the Bluetooth module.

In some embodiments, the processor may not be provided on the weighted vest. For example, the processor may be a remote server or a terminal server; the remote server may be a cloud server on the Internet, and the terminal server may be a smartphone, a smart wearable device, a laptop, an app, etc., bound to the weighted vest.

In some embodiments, the processor may be provided on the weighted vest.

In some embodiments, a miniature processor may be provided on the weighted vest. The miniature processor may be wired or wirelessly connected to the physiological monitoring module and the vest state monitoring module for data acquisition and simple processing. The miniature processor may interact with the processor (e.g., the terminal server) and share data. In some embodiments, the miniature processor may include a communication module and a reminder module. The communication module may be configured to acquire sensor data and transmit the sensor data to the processor. The reminder module may be configured to alert the user, for example, through a voice prompt, a flashing light, a vibration, etc. More descriptions of the miniature processor and the reminder module may be found in the related descriptions below.

In some embodiments, the simple processing of the miniature processor refers to simple calculations or logic. For example, a process of statistical analysis of historical weight data may be performed by the processor (e.g., a remote server), with the miniature processor receiving a statistical feature and a probability threshold from the processor and making a judgment. In some embodiments, the simple processing of the miniature processor may include: obtaining a training plan from the processor, determining whether a current weight satisfies the training plan; if the current weight does not satisfy the training plan using the reminder module to alert the user to adjust a weight distribution. For example, if the training plan is for beginners, a corresponding weight may be in a range of 5-8 kg, and the current weight is 10 kg, the user may be reminded to reduce the weight. By way of example, based on the weight data, the weight distribution may be determined, and whether weights on two sides are balanced (i.e., equal or close) may be determined. If the weights on the two sides are unbalanced, the user may be reminded to adjust a position of the weight pocket, for example, adjusting a relative position of the first weight pocket 120 or the second weight pocket 220 with respect to the one or more traverse fixing strips 124. By way of example, based on physiological data such as body temperature, whether cooling is need may be determined, and a corresponding alert may be issued or a control operation may be performed. For example, if the body temperature is too high, the user may be reminded to turn on the neck-hanging fan or activate the cooling function of the water pocket, and the control operation may include turning on a corresponding switch (e.g., by physically turning the switch on or turning the switch on through a smartphone) after assessment.

In some embodiments, the miniature processor may send various types of data to the terminal server (e.g., the app bound to the weighted vest) for the user to view. The terminal server may perform statistical analysis on the data.

The physiological data refers to data related to the physiological feature of the user, including data related to a heart rate, electrocardiogram, body temperature, respiration, or the like. In some embodiments, the physiological data may be collected through the physiological monitoring module.

The vest data refers to data related to a vest size, position, weight, etc. For example, the vest data may include wearing data (e.g., a size of the weighted vest after wearing, a relative position of the first shoulder straps 110 and the second shoulder straps 210, etc.), weights, or the like. In some embodiments, the vest data may be collected through the vest state monitoring module.

In some embodiments, the processor may be configured to: obtain the physiological data and the vest data; determine, based on the vest data, a user feature, weight data, and wearing data of the weighted vest; and determine an adjustment recommendation based on the physiological data, the user feature, the weight data, and the wearing data.

The user feature refers to a feature related to a current wearer of the weighted vest, such as user body shape data, user ID, etc.

In some embodiments, the processor may be configured to determine the user feature and the wearing data of the weighted vest based on the physiological data and the vest data, including: extract the relative position and angle data of the first shoulder straps and the second shoulder straps based on the vest data, determine a position and angle data of the fixing strap, determine the size of the weighted vest after wearing, and determine a current user ID based on the size after wearing and the physiological data. The relative position and angle data of the first shoulder straps and the second shoulder straps may be obtained through the gyroscope provided at the bend of the first shoulder straps and the second shoulder straps as described above; the position and angle data of the fixing strap may be obtained through the two position sensors provided on the two sides of the fixing strap and the waist positions of the first vet body and the second vet body as described above.

In some embodiments, the processor may be configured to compare the vest data with reference vest data and determine a size after wearing with a high similarity corresponding to the reference vest data as the size of the weighted vest after wearing. The reference vest data may include standard data corresponding to users with different body shapes (different heights, waist circumferences, shoulder widths, chest circumferences, etc.), and the reference vest data may be obtained through wearing tests on users with different body shapes. In some embodiments, the reference vest data may further include physiological data (referred to as test physiological data) obtained synchronously during the wearing tests. The processor may compare current physiological data with the test physiological data to further determine the size of the weighted vest after wearing. In some embodiments, the processor may determine the current user ID based on the size of the weighted vest after wearing, including: comparing the size of the weighted vest after wearing with a historical size after wearing data, and determining a user ID corresponding to the historical size after wearing data with a high similarity as the current user ID. The similarity may be determined using a similarity algorithm, for example, the similarity algorithm may include cosine similarity calculation, Euclidean distance calculation, etc.

The weight data may include current weight data, such as a load weight, a distribution of load weights, etc.

In some embodiments, the weighted vest may further include a plurality of elastic components (e.g., a plurality of elastic threads), with one end of the elastic component fixedly connected to the bottom of the weighted vest (near the hips after wearing), and another end of the elastic component connected to sensors (e.g., tension sensors) placed on the shoulders. When gravity varies, deformation of the elastic components differs, based on which the load weight and the distribution of the load weights may be determined, thereby determining the weight data.

In some embodiments, the processor may be configured to obtain pressure sensor data based on the pressure sensor placed on the inner side (i.e., the side in contact with the user's body) of the first shoulder strap, compare the pressure sensor data with the reference vest data, and determine the weight data. For example, during a wearing test, weight elements are placed at different positions of the weight pocket (e.g., the first weight pocket 120 and/or the second weight pocket 220), or weight elements with different weights are placed at a position of the weight pocket, then the pressure sensor data during the test may be obtained. Since the weights of the weight elements are known, a relationship between the pressure sensor data and the weight elements at the different positions or with different weights may be determined. The processor may compare current pressure sensor data with the pressure sensor data obtained during the wearing test and determine the weight data based on the relationship.

In some embodiments, the weight data may be input and determined by the user on a remote server or terminal server.

The adjustment recommendation refers to a recommendation provided to the user for adjusting the weighted vest. In some embodiments, the adjustment recommendation may include adjusting a weight, adjusting a position of the first shoulder straps, adjusting a position of the second shoulder straps, and adjusting a wearing position of the first vet body and the second vet body. The adjustment recommendation may be communicated to the user through the reminder module described above. For example, the reminder module may broadcast a verbal reminder to the user.

In some embodiments, the processor may be configured to determine the adjustment recommendation based on the physiological data, the user feature, the weight data, and the wearing data. For example, the processor may determine a relative position of a body part of the user and a sensor corresponding to the body part based on an accuracy of the physiological monitoring module; determine a target position of the first shoulder straps or the second shoulder straps, or a target position of the first vet body and the second vet body based on the relative position; and determine the adjustment recommendation based on the target position.

The accuracy of the physiological monitoring module may be determined in various ways. For example, the closer the physiological data obtained is to standard physiological data, the higher the accuracy is. As another example, the more sensitive a numerical change of the physiological monitoring module is, the higher the accuracy is. It may be understood that for the physiological monitoring module, the higher the accuracy is, the closer the physiological monitoring module is to the user's body. For example, the higher the accuracy of a respiratory sensor is, the smaller a distance between the respiratory sensor and the user's abdomen, and the higher the accuracy of an electrocardiogram (ECG) sensor is, the smaller a distance between the ECG sensor and the user's heart. In some embodiments, the processor may establish a comparison table between accuracies and distances. For example, if the accuracy of an ECG sensor is 95%, the distance between the ECG sensor and the user's heart may be 0˜3 CM. The relative positions (e.g., the distance between the ECG sensor and the user's heart) of the user's body parts and the corresponding sensors may be determined based on the accuracy of the physiological monitoring module.

The target position refers to a position where the weighted vest matches the user's body shape and where the physiological monitoring module matches various parts of the user's body. When the weighted vest is at the target position, it may be determined that the shoulders and the waist of the user match the weighted vest, and the sensors of the weighted vest correspond to various parts of the user's body. In some embodiments, the processor may determine relative positions and select a position with a smallest relative position (e.g., the position where the ECG sensor matches the user's heart) as the target position. For example, if the relative position is a distance of 5 cm between the ECG sensor and the user's heart, with an orientation of the ECG sensor being below the heart (the orientation may be determined by the vest state monitoring module, such as the gyroscope), and the ECG sensor is located at position A currently, then the target position may be a position where the weighted vest moves up by 5 cm. In this case, the adjustment recommendation may be to increase a length at which the first shoulder straps and the second shoulder straps overlap by 5 cm.

In some embodiments, the processor may determine whether to adjust the weight based on historical weight data corresponding to the user feature. For example, the processor may statistically analyze the historical weight data corresponding to the user ID to obtain statistical features and determine whether to adjust the weight based on the statistical features. The statistical features refer to statistical features of the data, including a maximum weight value, a minimum weight value, an average weight value, a weight variance, a weight probability, etc., of the weight. In some embodiments, if the weight exceeds the maximum weight value or minimum weight value, an adjustment may be needed. The corresponding adjustment recommendation may include reducing or increasing the weight. The maximum weight value and minimum weight value of the weight may be preset.

In some embodiments, the processor may determine a weight probability based on historical weight data corresponding to the user ID, and determine whether a weight probability corresponding to a current weight is less than a probability threshold. If the weight probability corresponding to the current weight is less than the probability threshold, the adjustment is needed; and if the weight probability corresponding to the current weight is not less than the probability threshold, no adjustment is needed.

The weight probability refers to frequencies corresponding to different weights. The processor may statistically analyze a distribution of weight probabilities based on historical weight data. For example, in the statistical analysis of historical weight data for the current user ID, the weight probabilities for weights of 4 KG, 5 KG, and 6 KG together are 80%, the weight probability for weights above 8 KG is 5%, and the weight probability for weights below 5 KG is 15%. In some embodiments, the processor may select a historical weight corresponding to the current weight from the distribution of weight probabilities and determine whether the weight probability corresponding to the historical weight is less than the probability threshold. For example, if the current weight is 8 KG and the weight probability for weights above 8 KG is 5%, which is less than the probability threshold of 10%, then an adjustment is suggested. However, if the current weight is 5 KG and the weight probability for weights of 5 KG is 25%, which is not less than the probability threshold of 10%, then no adjustment is needed. The probability threshold may be pre-set.

In some embodiments, the weighted vest may further include an exercise monitoring module, which may be configured to collect exercise data. The exercise monitoring module may include an acceleration sensor, a gyroscope, etc., and may be communicatively connected with the processor. More descriptions of the communicative connection may be found in the related descriptions above.

The exercise data refers to data related to user exercise, including a type of exercise, an intensity, a duration, a distance, a weight, etc. The processor may obtain the exercise data from the exercise monitoring module.

In some embodiments, the processor may be further configured to determine a fatigue level based on the physiological data and the exercise data; and issue a reminder based on the fatigue level. In some embodiments, the reminder may include at least one of a fatigue warning and an operation reminder.

The fatigue level refers to a degree of fatigue experienced by the user after exercise, which may be represented numerically, with a higher numeric value indicating a greater fatigue level. In some embodiments, the processor may determine the fatigue level in various ways. For example, if there is a sustained increase in the heart rate over a time period in the physiological data, it may indicate a high fatigue level. As another example, a high respiratory rate in the physiological data or high intensity, long duration, and heavy weight in the exercise data may indicate a high fatigue level.

In some embodiments, the processor may determine the fatigue level based on the physiological data, the exercise data, and the vest data. For example, the processor may compare the physiological data with reference physiological data to determine a first similarity degree; determine an exercise expenditure based on the exercise data; and determine a fatigue level of a current user based on the exercise expenditure and the first similarity degree.

The reference physiological data refers to physiological data obtained when the user is engaging in easy or relaxed exercise. In some embodiments, the reference physiological data may be obtained as follows: collecting physiological data of the user during a time period between T1 and T2 when engaging in a plurality of same exercises, determining an average value of each indicator of the user's physiological data during the time period between T1 and T2 as a value of the each indicator in the reference physiological data. The same exercises refer to exercises of a same duration, intensity, and weight for the user, which may be determined by statistical analysis of exercise data from a plurality of users. In some embodiments, the reference physiological data may be physiological data of users of different body shapes in a non-exercise (relaxed) state, which may be made public by a medical device, a smart wearable institution, or other organizations, and the processor may download the reference physiological data from the internet.

The first similarity degree refers to a degree of similarity between the physiological data and the reference physiological data. A numerical value of the first similarity degree is greater than 1, and the closer the numerical value of the first similarity degree is to 1, the more similar the physiological data is to the reference physiological data, i.e., the higher the first similarity degree is; conversely, the larger the numerical value is, the lower the first similarity degree is.

In some embodiments, the exercise expenditure may be determined based on the exercise data. By way of example, the exercise expenditure may be determined as a product of exercise intensity, exercise duration, and a coefficient. The coefficient may be related to the heart rate, the respiratory rate, the user weight, etc.

In some embodiments, the fatigue level of current user may be determined as a ratio of the exercise expenditure to the first similarity degree. If the user has a physical fitness, even though the exercise expenditure is relatively high, the physiological data of the user remains relatively similar to the reference physiological data during relaxation. In this case, it may be considered that the current user is in a relaxed state. By comprehensively assessing the fatigue level based on the exercise expenditure and the first similarity degree, and taking into account the physical fitness of the user, the fatigue level can be determined more accurately.

The processor may determine whether to issue the reminder in various ways. For example, based on the heart rate or respiratory data of the physiological data, the processor may determine whether a current heart rate or respiration is within a preset normal range. If the heart rate or respiratory data remains outside the normal range for a long time, the processor may issue the reminder, which may indicate a need for the user to rest.

In some embodiments, the processor may issue the reminder in response to determining that the fatigue level exceeds a fatigue threshold. The fatigue threshold may be preset. The reminder may include a fatigue warning, which refers to a warning about the fatigue level. The fatigue warning may be issued by the reminder module, for example, through sound (e.g., long beeping, voice announcements), a change in lighting, a vibration pattern, etc. In some embodiments, the reminder may also be issued by the terminal server, for example, through sound or vibration on a terminal device or app.

In some embodiments, the reminder may include an operation reminder, which refers to a reminder about an operation of the weighted vest, such as reducing the weight or adjusting the weighted vest. The operation reminder is similar to the adjustment recommendation described above and will not be repeated here.

In some embodiments of the present disclosure, through the adjustment recommendation or the reminder, the weight, size, etc., of the weighted vest can be better tailored to the body shape of the user. By utilizing the exercise data and the fatigue level, recommendations for rest or adjustments can be given, enabling personalized adaptation of the weighted vest for different users and enhancing user comfort.

Having thus described the basic concepts, it may be rather apparent to those skilled in the art after reading this detailed disclosure that the foregoing detailed disclosure is intended to be presented by way of example only and is not limiting. Various alterations, improvements, and modifications may occur and are intended to those skilled in the art, though not expressly stated herein. These alterations, improvements, and modifications are intended to be suggested by this disclosure, and are within the spirit and scope of the exemplary embodiments of this disclosure.

Moreover, certain terminology has been used to describe embodiments of the present disclosure; For example, the terms “one embodiment,” “an embodiment,” and/or “some embodiments” mean that a particular feature, structure, or feature described in connection with the embodiment is included in at least one embodiment of the present disclosure; Therefore, it is emphasized and should be appreciated that two or more references to “an embodiment” or “one embodiment” or “an alternative embodiment” in various portions of this disclosure are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or features may be combined as suitable in one or more embodiments of the present disclosure;

Furthermore, the recited order of processing elements or sequences, or the use of numbers, letters, or other designations therefore, is not intended to limit the claimed processes and methods to any order except as may be specified in the claims. Although the above disclosure discusses through various examples what is currently considered to be a variety of useful embodiments of the disclosure, it is to be understood that such detail is solely for that purpose, and that the appended claims are not limited to the disclosed embodiments, but, on the contrary, are intended to cover modifications and equivalent arrangements that are within the spirit and scope of the disclosed embodiments. For example, although the implementation of various components described above may be embodied in a hardware device, it may also be implemented as a software only solution, e.g., an installation on an existing server or mobile device.

As another example, it should be appreciated that in the foregoing description of embodiments of the present disclosure, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure aiding in the understanding of one or more of the various inventive embodiments. This way of disclosure, however, is not to be interpreted as reflecting an intention that the claimed subject matter requires more features than are expressly recited in each claim. Rather, inventive embodiments lie in less than all features of a single foregoing disclosed embodiment.

In some embodiments, the numbers expressing quantities or properties used to describe and claim certain embodiments of the present disclosure are to be understood as being modified in some instances by the term “about,” “approximate,” or “substantially.” For example, “about,” “approximate,” or “substantially” may indicate ±20% variation of the value it describes, unless otherwise stated. Accordingly, in some embodiments, the numerical parameter set forth in the written description and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by a particular embodiment. In some embodiments, the numerical parameter should be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameter setting forth the broad scope of some embodiments of the present disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as practicable.

Each of the patents, patent applications, publications of patent applications, and other material, such as articles, books, specifications, publications, documents, things, and/or the like, referenced herein is hereby incorporated herein by this reference in its entirety for all purposes, excepting any prosecution file history associated with same, any of same that is inconsistent with or in conflict with the present document, or any of same that may have a limiting effect as to the broadest scope of the claims now or later associated with the present document. By way of example, should there be any inconsistency or conflict between the description, definition, and/or the use of a term associated with any of the incorporated material and that associated with the present document, the description, definition, and/or the use of the term in the present document shall prevail.

In closing, it is to be understood that the embodiments of the present disclosure disclosed herein are illustrating of the principles of the embodiments of the present disclosure. Other modifications that may be employed may be within the scope of the present disclosure. Thus, by way of example, but not of limitation, alternative configurations of the embodiments of the present disclosure may be utilized in accordance with the teachings herein. Accordingly, embodiments of the present disclosure are not limited to that precisely as shown and described.
