Adjustable dumbbells allow the user to train using selected weights within a weight range while reducing the need for a single dumbbell with a range of weights within the same weight range. Adjustable dumbbells include handles or other support bars, which can then have one or more weight plates, optionally attached to the support bars. to increase The weight of the dumbbells is adjustable, and the user simply attaches or attaches additional weight plates to the handles until the desired weight is achieved. In some embodiments, the adjustable dumbbells may be hand weights. An example of an adjustable dumbbell is shown in US Patent No. 9,795,822, which is hereby incorporated by reference in its entirety. For example, the handle can be sized such that the space between the two sets of weight plates is wide enough for a single hand. In some embodiments, the adjustable dumbbells may be long bars, such as those used for squats, bench presses, and the like. The width of the bar between each set of weight plates may be sufficient to separate the hands (eg, greater than shoulder length apart). In some embodiments, the adjustable dumbbells may be weights for the weight machine. In some embodiments, adjustable dumbbells may have a single set of weight plates, such as for kettlebells.

In some embodiments, the adjustable dumbbell may include a plate adjustment mechanism that connects selected weight plates to the adjustable dumbbell until a desired weight is achieved. Regardless of how the selected weight plates are attached to the handle, the user may not always attach all of the weight plates to the handle at the same time. Thus, when the user removes the handle from the bracket, one or more unselected weight plates may remain behind the bracket. These non-selected weight plates may fall off the bracket. In at least one embodiment, a non-selected weight plate removed from the carriage may become a safety hazard and may fall on the user, be left on the floor to be tripped over, or present another safety hazard. Additionally, in at least one embodiment, non-selected weight plates that are removed from the carriage may become misaligned. For example, an unselected weight plate may be stolen, lost, placed in the wrong plate, or otherwise misplaced.

To prevent unselected weight plates from falling out of the bracket, the bracket may include a retaining mechanism. A retention mechanism may secure unselected weight plates to the carriage while allowing selected weight plates to be removed from the carriage while attached to the handle. In this way, non-selected weight plates may not shift and therefore may not pose a safety hazard or be misplaced. Securing non-selected weight plates to the brackets further improves the user's training experience by eliminating the need for the user to consciously attend to non-selected weight plates.

FIG. 3 is a representation of an embodiment of a bracket 306 in accordance with at least one embodiment of the present disclosure. Bracket 306 includes a plurality of weight plate receptacles 314 . Each weight plate receptacle is configured to receive a weight plate (eg, weight plate 104 of FIG. 1-1 ). The weight plate receptacle shown is a recess in the bracket 306 that aligns and helps position the weight plate relative to the bracket 306 . Latches (collectively 310 ) are shown in or at the edge of each weight plate receptacle 314 . The latch 310 is configured to secure the weight plate to the bracket 306 in the weight plate receptacle 314 .

In the illustrated embodiment, a first plurality of latches 310 - 1 is located on a first side of the weight plate receptacle 314 and a second plurality of latches 310 - 2 is located on a second side of the weight plate receptacle 314 . Including latches 310 on either side of the weight plate receptacle 314 may allow for a simplified retention mechanism, or allow the retention mechanism increased control over which weight plates are selected and deselected.

4 is a cross-sectional view of a weight plate 404 and a retention mechanism 416 in accordance with at least one embodiment of the present disclosure. The weight plate 404 is included in the top table Handle space 418 in face 420 into which a handle (eg, handle 102 of FIG. 1-1 ) may be inserted. The weight plate 404 further includes notches 408 (collectively 422 ) in the sides. In the illustrated embodiment, the weight plate 404 includes notches 408 in both the first side 422-1 and the second side 422-2.

The notch 408 includes a notch engagement angle 424 , which is the angle measured clockwise between the notch engagement surface 426 and the second side 422 - 2 . In some embodiments, the notch engagement angle 424 may have an upper limit, a lower limit, or include 45°, 60°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 120°, 135°, within the range of the upper limit and lower limit, or any value between them. For example, notch engagement angle 424 may be greater than 45°. In another example, notch engagement angle 424 may be less than 135°. In yet another example, notch engagement angle 424 may be any value within a range between 45° and 135°. A notch engagement angle 424 of approximately 90° provides maximum force to secure the weight plate to the bracket. In some embodiments, a notch engagement angle 424 of less than 135° may be critical to provide sufficient force to secure the weight plate to the bracket.

The latch 410 includes a protrusion 428 that extends into the notch 408 . In the illustrated embodiment, protrusion 428 has a triangular cross-sectional shape. The protrusion 428 has a latch engaging surface 430 that engages the notch engaging surface 426 . In the illustrated embodiment, the notch engaging surface 426 has the same shape as the latch engaging surface. In this manner, the bearing surface between the latch engaging surface 430 and the notch engaging surface 426 is maximized. Because the protrusion 428 is inserted into the notch 408, when a removal force is applied to the weight plate 404, the protrusion 428 contacts the notch. Engaging surface 426 contacts the notch. Interference between notch 408 and protrusion 428 secures weight plate 404 to the bracket.

The protrusion includes a latch engagement angle 432, which is the angle measured clockwise between the latch engagement surface 430 and a line 433 parallel to the first side 422-1. In some embodiments, the latch engagement angle 432 may have an upper limit, a lower limit, or include 45°, 60°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 120°, 135°, within the range of the upper limit and lower limit, or any value between them. For example, the latch engagement angle 432 may be greater than 45°. In another example, the latch engagement angle 432 may be less than 135°. In yet another example, the latch engagement angle 432 may be any value within a range between 45° and 135°. A latch engagement angle 432 of approximately 90° provides maximum force to secure the weight plate to the bracket. In some embodiments, a latch engagement angle 432 between 75° and 105° may be critical to provide sufficient force to secure the weight plate to the bracket.

In some embodiments, the latch engagement corner 432 and the notch engagement corner 424 are complementary. In other words, the latch engagement angle 432 and the notch engagement angle 424 add up to 180°. Complementary latch engagement corner 432 and notch engagement corner 424 can increase the bearing surface between the latch engagement surface and the notch engagement surface. This increases the force securing the weight plate to the bracket. In some embodiments, the latch engagement angle 432 and the notch engagement angle 424 are not complementary and may add up to an angle greater or less than 180°.

The latch 410 includes a latch arm 434 extending from the protrusion 428 . In the illustrated embodiment, the latch arm 434 rotates about a pivot 436 . Holding Agency 416 A latch camshaft 438 is included which includes lobes 439 . As the latch camshaft 438 rotates, the lobes 439 push the lower portion 440 of the latch arm 434 . As lobe 439 pushes lower portion 440 , latch arm 434 rotates about pivot 436 and upper portion 442 of latch arm 434 rotates toward notch 408 (counterclockwise in the view shown). This may insert protrusion 428 into notch 408 . As the latch camshaft 438 rotates further, the lug rotates away from the lower portion 440 and a resilient member (not shown) may urge the latch arm 434 to rotate about the pivot 436 (clockwise in the view shown). This may cause upper portion 442 and protrusion 428 to dislodge from notch 408 , thereby releasing weight plate 404 from the bracket and allowing weight plate 404 to be removed.

5-1 is a top view of an adjustable dumbbell system 500 in accordance with at least one embodiment of the present disclosure. In the illustrated embodiment, the adjustable dumbbell system 500 includes a first dumbbell 501-1 and a second dumbbell 501-2.

The plate adjustment mechanism 544 includes a plate camshaft gear 545 connected to a plate camshaft (not shown). The plate master gear 546 rotates the plate camshaft gear which rotates the plate camshaft to selectively select the counterweight plates (collectively 504) for connection to the first handle 502-1 and the second handle 502-2, respectively . The main plate gear 546 is connected to the main shaft 547 .

The retention mechanism 516 includes a latch cam gear 548 connected to a latch camshaft (not shown). Latch master gear 549 rotates latch cam gear 548 , which rotates a latch camshaft to selectively insert latch 510 into a slot (not shown) in weight plate 504 . The latch main gear 549 is driven by the main shaft 547 . In this way, the plate adjustment mechanism 544 and the holding mechanism 516 mechanical connections. In other words, the board adjustment mechanism 544 and the holding mechanism 516 are connected through a gear connection.

11-1 is a perspective view of an adjustable dumbbell assembly 1100 in accordance with at least one embodiment of the present disclosure. Brackets 1106 support weight plates 1104 and handles 1102 . Handle 1102 includes a plate adjustment mechanism that selectively connects weight plate 1104 to handle 1102 . The plate adjustment mechanism is driven by a motor under the carriage 1106 .

11-2 is another perspective view of the adjustable dumbbell assembly 1100 of FIG. 11-1. A motor 1193 below the bracket 1106 can control the plate adjustment mechanism. The motor 1193 rotates the first gear shaft (not shown) and the second gear shaft 1194-2. The first gear shaft and the second gear shaft 1194 - 2 are connected through a plate gear belt 1195 . Therefore, the first gear shaft and the second gear shaft 1194-2 may rotate at the same speed.

11-3 is a top view of the bracket 1106 of FIG. 11-1 including a plate adjustment mechanism 1144 in accordance with at least one embodiment of the present disclosure. The plate adjustment mechanism includes a first gear shaft 1194-1 and a second gear shaft 1194-2. The first gear shaft 1194-1 and the second gear shaft 1194-2 are driven by the motor 1193 shown in Fig. 11-2. The first pinion 1196-1 is connected to the first gear shaft 1194-1, and the second pinion 1196-2 is connected to the second gear shaft 1194-2. The first pinion 1196-1 drives the first rack 1197-1 on the first plate extension bar 1198-1 and the second pinion 1196-2 drives the second rack 1197-1 on the second plate extension bar 1198-2. 2.

The first plate extension bar 1198-1 and the second plate extension bar 1198-2 extend into a series of voids in the weight plate 1104 shown in FIG. 11-1. The extension lengths of the first plate extension rod 1198 - 1 and the second plate extension rod 1198 - 2 determine the number of weight plates 1104 connected to the handle 1102 . In this way, by rotating the first gear shaft 1194-1 and the second gear shaft 1194-2, the weight plate 1104 can be selected.

11-4 is a cross-sectional view of the adjustable dumbbell assembly 1100 of FIG. 11-1 in accordance with at least one embodiment of the present disclosure. Adjustable dumbbell assembly 1100 includes a plate adjustment mechanism 1144 in handle 1102 and a retention mechanism 1116 in bracket 1106 . Plate adjustment mechanism 1144 and retention mechanism 1116 are driven by the same mechanism. Specifically, the first gear shaft 1194-1 drives the first plate extension rod 1198-1 and the first holder extension rod 1199-1, and the second plate gear shaft 1194-2 drives the second board extension rod 1198-2 and the second holder extension rod 1198-1. Extension Rod 1199-2. Accordingly, plate adjustment mechanism 1144 may be mechanically coupled to retention mechanism 1116 . In other words, when the plate adjustment mechanism 1144 connects the weight plate 1104 When attached to handle 1102 , retaining mechanism 1116 may, in conjunction with the same operation of motor 1193 , secure one or more unselected weight plates 1104 to bracket 1106 .

Bracket 1106 includes retention mechanism slot 1103 . As the first gear shaft 1194-1 rotates, a first retention pinion (not shown) on the first gear shaft 1194-1 may engage a first retention rack on the first retention extension rod 1199-1. This can cause the first retention extension bar 1199-1 to extend into the retention mechanism slot 1103 where it can engage one or more latches. One or more latches may engage one or more unselected weight plates 1104, securing them to the bracket. Similarly, as the second gear shaft 1194-2 rotates, the second retention pinion 1105-2 on the second gear shaft 1194-2 can engage the second retention rack on the second retention extension rod 1199-2. This can cause the second retention extension bar 1199-2 to extend into the retention mechanism slot 1103 where it can engage one or more latches. One or more latches may engage one or more unselected weight plates 1104, securing them to the bracket.

In some embodiments, each weight plate 1104 may be connected to each other via an interlocking connection 1107 . For example, in the illustrated embodiment, the interlocking connection may allow the weight plates 1104 to be separated from each other using an upward force, but may prevent separation from each other using a downward or longitudinal force (eg, parallel to the handle 1102). In some embodiments, interlock connection 1107 may be a dovetail connection. In some embodiments, interlock connection 1107 may be any type of interlock connection.

Interlocking connections 1107 can help keep all non-selected weight plates 1104 oriented in the same direction. In this way, the handle 1102 and the selector The selected weight plates 1104 can be removed from the brackets 1106, and all unselected weight plates 1104 can remain upright in the brackets 1106. This may allow handle 1102 and selected weight plate 1104 to be easily reinserted into bracket 1106 without having to align unselected weight plates in bracket 1106 .

In some embodiments, retention mechanism 1116 may include retention protrusions 1109 at either end of bracket 1106 . Retaining protrusions 1109 may extend into end weight plates 1111 . End weight plates 1111 may be connected to other weight plates 1104 via interlocking connections 1107 . Thus, when handle 1102 is removed, end weight plate 1111 may remain fixed to bracket 1106 and remaining non-selected weight plates 1104 may remain oriented relative to end weight plate 1111 via interlocking connection 1107 . Thus, the end weight plates 1111 may be the only weight plates secured to the bracket 1106 and the remaining weight plates 1104 may remain upright based on the interlocking connection 1107 with the end weight plates 1111 .

In some embodiments, retention protrusion 1109 may be rigidly attached to bracket 1106 . For example, retention protrusion 1109 may have a height and/or position relative to bracket 1106 that does not change based on actuation of plate adjustment mechanism 1144 . In some embodiments, retention protrusion 1109 can be actuated. For example, retention protrusion 1109 may have an adjustable height and may only extend into end weight plate 1111 when retention mechanism 1116 engages retention protrusion 1109 . In other examples, the end weight plates 1111 may be secured to the bracket 1106 using latches on the sides of the end weight plates 1111 or any other mechanism described herein.

FIG. 12 is a schematic diagram of an adjustable dumbbell control system 1223 in accordance with at least one embodiment of the present disclosure. Adjustable dumbbell control system 1223 Can be used to control any of the adjustable dumbbells and associated hardware discussed in this article. For example, adjustable dumbbell control system 1223 may be used to control adjustable dumbbell system 100 of FIG. 1 , adjustable dumbbell system 200 of FIG. 2 , bracket 306 of FIG. 3 , retaining mechanism 416 of FIG. -2 adjustable dumbbell system 500, adjustable dumbbell 600 in FIG. 6, adjustable dumbbell 700 in FIG. 7, holding mechanism 816 in FIG. 8, adjustable dumbbell assembly 900 in FIG. 9, FIG. 11-1 to FIG. 11-4 The adjustable dumbbell assembly 1100 of , and combinations thereof. Adjustable dumbbell control system 1223 may be used to perform method 1086 of FIG. 10 .

Adjustable dumbbell control system 1223 includes adjustable dumbbell system 1200 . Adjustable dumbbell system 1200 may include a weight controller 1213 . The weight controller 1213 may be configured to attach a weight plate to the handle based on a set weight. Weight controller 1213 may receive a set weight from weight selection input 1215 . The user can enter a set weight into the weight selection input 1215, and based on the set weight entered into the weight selection input, the weight controller 1213 can attach the appropriate number of plates to the handle to set the adjustable dumbbell to the set weight. In this way, by using the weight selection input 1215, the user can increase the control over his or her training. This can improve the training experience.

According to embodiments of the present disclosure, the weight controller 1213 may connect the weight plate to the handle using any of the structures, mechanisms, actuators, or other devices discussed herein. For example, weight controller 1213 may activate one or more latches to secure a selected weight plate to the handle. In some examples, weight controller 1213 may activate one or more latches to secure unselected weight plates to the bracket. In some embodiments, based on the set weight, the weight The volume controller 1213 may identify combinations of weight plates to attach to the handle. The weight controller 1213 may then connect the identified combination of weight plates to the handle using any of the mechanisms discussed herein. In some embodiments, the weight controller 1213 may connect unselected or identified weight plates to the bracket to reduce the risk of loss or injury due to a loose weight plate.

In some embodiments, weight selection input 1215 may use any type of input to receive a set weight. For example, the user may enter a set weight into the weight selection input 1215 with a verbal command. For example, the user can speak commands such as "set the weight to 15 lbs." A microphone on voice recognition input 1217 can receive spoken commands, and voice recognition software can process the spoken commands to determine a set weight. After processing the spoken command, voice recognition input 1217 may communicate the set weight to weight controller 1213.

In some embodiments, weight selection input 1215 may receive a set weight from remote computing device 1219 . The remote computing device 1219 can send the set weight at the weight selection input 1215 to the communication device, which can then send the set weight to the weight controller 1213. The weight controller 1213 can then attach the appropriate weight plate to the handle to achieve the set weight.

In some embodiments, weight selection input 1215 may receive a set weight from one or more buttons 1221 on the cradle, or otherwise connected to adjustable dumbbell system 1200 . Buttons 1221 may include specific set weights, specific weight plates attached to the handle, weight increments, activities related to set weights, any other button input, and combinations thereof.

In some embodiments, adjustable dumbbell system 1200 may also include a display 1225 . Display 1225 may include training information related to adjustable dumbbells.

In some embodiments, display 1225 may include one or more elements of weight selection input 1215 . For example, display 1225 may include one or more buttons 1221 . In some embodiments, display 1225 may be a touch-sensitive display, and button 1221 may be a designated portion of the touch-sensitive display. In some embodiments, display 1225 may provide instructions to the user to provide verbal commands to adjustable display system 1200 . In some embodiments, display 1225 may provide information received from remote computing device 1219 .

FIG. 13 is a representation of a method 1327 for securing an adjustable dumbbell in accordance with at least one embodiment of the present disclosure. Method 1327 may be performed by adjustable dumbbell control system 1223 of FIG. 12 .

According to an embodiment of the present disclosure, method 1327 may include receiving a set weight from a weight selection input at 1329 . For example, the weight selection input may include voice recognition input, and setting the weight may be entered using spoken commands from the user. In some examples, the set weight may be entered using buttons, may be received from a remote computing device, or may be entered using any other input mechanism.

At 1331, based on the received/input set weight, one or more weight plates may be selectively connected to the handle to set the adjustable dumbbell to the set weight. In some embodiments, the weight controller can identify which weight plates to attach to the handle to achieve a set weight, and can provide instructions to the adjustment mechanism to attach the weight plates to the handle. Any unselected weight plates may be connected to the bracket at 1335. An unselected weight plate can be a weight plate that is not attached to the handle. In some embodiments, the weight controller may identify unselected weight plates.

Industrial utilization

Adjustable dumbbells allow the user to train using selected weights within a weight range while reducing the need for a single dumbbell with a range of weights within the same weight range. Adjustable dumbbells include handles or other support bars, which can then have one or more weight plates, optionally attached to the support bars. To increase the weight of an adjustable dumbbell, the user simply attaches or attaches additional weight plates to the handles until the desired weight is achieved. In some embodiments, the adjustable dumbbells may be hand weights. For example, the handle can be sized such that the space between the two sets of weight plates is wide enough for a single hand. In some embodiments, the adjustable dumbbells may be long bars, such as those used for squats, bench presses, and the like. The width of the bar between each set of weight plates may be sufficient to separate the hands (eg, greater than shoulder length apart). In some embodiments, the adjustable dumbbells may be weights for the weight machine. In some embodiments, adjustable dumbbells may have a single set of weight plates, such as for kettlebells.

In some embodiments, the adjustable dumbbell may include a plate adjustment mechanism that connects selected weight plates to the adjustable dumbbell until a desired weight is achieved. Regardless of how the selected weight plates are attached to the handle, the user may not always attach all of the weight plates to the handle at the same time. Thus, when the user removes the handle from the bracket, one or more unselected weight plates may remain behind the bracket. These non-selected weight plates may fall off the bracket. In at least one embodiment, a non-selected weight plate removed from the carriage may become a safety hazard and may fall on the user, be left on the floor to be tripped over, or present another safety hazard. Additionally, in at least one embodiment, non-selected weight plates that are removed from the carriage may become misaligned. For example, an unselected weight plate may be stolen, lost, placed in the wrong plate, or otherwise misplaced.

To prevent unselected weight plates from falling out of the bracket, the bracket may include a retaining mechanism. A retention mechanism may secure unselected weight plates to the carriage while allowing selected weight plates to be removed from the carriage while attached to the handle. In this way, non-selected weight plates may not shift and therefore may not pose a safety hazard or be misplaced. Securing non-selected weight plates to the brackets further improves the user's training experience by eliminating the need for the user to consciously attend to non-selected weight plates.

The plate adjustment mechanism can be located anywhere in the adjustable dumbbell system. In some embodiments, the plate adjustment mechanism may be located in the handle of the adjustable dumbbell. Dials or gears on the outer edge of an adjustable dumbbell allow the handle to turn a shaft that includes a plurality of plate adjustment cams. Plate adjustment cams can be selected Optionally insert the pin into the notch in the weight plate, thereby choosing the weight plate to attach or connect to the handle.

In some embodiments, adjustable dumbbells can be placed in the carriage, and the plate adjustment mechanism can be located in the carriage. The plate adjustment mechanism may include a protrusion in the bracket that extends into a cavity in the weight plate. The protrusions may have an adjustable height. In the upper position, the protrusion can push the latch on the support member connected to the handle inward, away from the notch in the cavity of the weight plate. This will separate the weight plate from the handle. In the lower position, the protrusion may not contact the latch, and the latch may be pushed through the resilient member into the notch in the cavity of the weight plate.

The bracket may include a retention mechanism that includes one or more latches. Each latch may be located on the bracket and selectively inserted into a notch on the weight plate. By inserting the latches into the slots, the retention mechanism secures non-selected weight plates to the bracket. In some embodiments, each weight plate may be associated with a latch. The retention mechanism selectively secures the latch to the associated weight plate when the adjustable dumbbell is placed in the carriage. In this manner, unselected weight plates may be secured to the carriage before the adjustable dumbbell with the selected weight plate attached to the handle is removed from the carriage. In at least one embodiment, securing non-selected weight plates to the bracket prior to the adjustable dumbbell being removed facilitates removal of the non-selected weight plate from the bracket when the adjustable dumbbell is removed. For example, a non-selected weight plate may be secured to the bracket.

In some embodiments, an adjustable dumbbell may include a plurality of weight plates located at both ends of the handle. In this way, the user can hold the handle and move the weight while holding the handle. In some embodiments, equal weights may be attached to the handle at either end. In some embodiments, unequal weights may be attached to the handle. In other words, the first end of the handle may have more weight secured thereto than the second end of the handle. This is probably because more weight plates are attached to the first end of the handle. In some embodiments, the retention mechanism may secure more unselected weight plates to the second end of the bracket than the first end of the bracket to accommodate unbalanced adjustable dumbbells.

In some embodiments, the retention mechanism may include a single latch that secures the plurality of weight plates to the bracket. For example, a single latch may include a bar that extends the entire length of the adjustable dumbbell. In some examples, a single latch may secure some, but not all, of the weight plates to the bracket. In some embodiments, a single latch can secure two, three, four, five, six, or more weight plates to the bracket. In some embodiments, a single adjustable dumbbell can include individual latches for each weight plate and bar latches that can secure multiple weight plates to the bracket. This can increase the stability of the connection between the weight plate and the bracket, prevent the weight plate from being dislocated, and prevent the weight plate from becoming a safety hazard.

In some embodiments, the weight plate is shaped like a plate. A board has a length, width and depth. In some embodiments, the length and width may be approximately the same, such as having a square, circle, or other equilateral polygon. In some embodiments, the length and width may vary, for example having a rectangular, elliptical or other polygonal or non-polygonal configuration. Length and width can be greater than the matching The depth of the heavy board. Thus, a weight plate may represent a plate, pan, or other planar structure. Depth may be the smallest dimension between any two faces of the weight plate.

The weight plate may include two bottom surfaces and at least one outer face extending along an outer circumference of the weight plate. In some embodiments, the depth may be the smallest measurement between the outer two edges. The base can have any cross-sectional shape, including circular, oval, square, rectangular, triangular, pentagonal, hexagonal, any-sided polygonal, non-polygonal, or other cross-sectional shape. Depending on the number of edges of the cross-sectional shape, the outer face may comprise one or more faces. For example, the outer face may include a top, a bottom opposite the top, and first and second sides transverse to the top and bottom, the first side being opposite the second side.

Each weight plate includes a notch. The notch can be located anywhere on the weight plate. In some embodiments, the notch can be located on the first bottom surface or the second bottom surface. In some embodiments, the notch can be located on the outer face, such as on the first side, the second side, both the first and second sides, the top surface, the bracket surface, and combinations thereof. In some embodiments, the notches are indentations, cavities or voids on the surface of the weight plate. In some embodiments, the notch may be located within the cavity of the weight plate.

The notch can have any number of sides, including 1, 2, 3, 4, 5, 6 or more sides. The edges of the slot can have any shape, including curved edges, straight edges, or a combination of curved and straight edges. Thus, the notches may have any shape, including hemispherical, cylindrical, triangular, square, rectangular, pentagonal, hexagonal, or any other shape.

In some embodiments, the latch of the retention mechanism includes a protrusion extending into the notch. In some embodiments, the protrusion can be triangular, pyramidal, hemispherical, cylindrical, conical, or any other shape that can be inserted into the slot.

In some embodiments, the latch engaging surface of the latch has a complementary shape to the slot engaging surface of the slot. For example, the latch engagement surface may be flat and at a latch engagement angle. The slot engaging surfaces may similarly be flat and have slot engaging corners. When activated, the notch may engage the notch at the notch engaging surface, and most or all of the latch engaging surface may contact most or all of the notch engaging surface. This can increase the load bearing area, which can help increase resistance to displacement and/or removal of non-selected weight plates.

In some embodiments, the latch engagement angle as measured counterclockwise with respect to the side may have an upper limit, a lower limit, or include 45°, 60°, 75°, 80°, 85°, 90°, 95° , 100°, 105°, 120°, 135° within the range of the upper limit and lower limit of any one of them, or any value between them. For example, the latch engagement angle may be greater than 45°. In another example, the latch engagement angle may be less than 135°. In yet another example, the latch engagement angle may be any value within a range between 45° and 135°. The close to 90° latch engagement angle provides maximum force to secure the weight plate to the bracket. In some embodiments, a latch engagement angle greater than 45° may be critical to provide sufficient force to secure the weight plate to the bracket.

In some embodiments, the notch engagement angle, as measured counterclockwise with respect to the side, may have an upper limit, a lower limit, or include 45°, 60°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 120°, 135° within the range of the upper limit and lower limit, or any value between them. For example, the notch engagement angle may be greater than 45°. In another example, the notch engagement angle may be less than 135°. In yet another example, the notch engagement angle may be any value within a range between 45° and 135°. A near 90° notch engagement angle provides maximum force to secure the weight plate to the bracket. In some embodiments, a notch engagement angle of less than 135° may be critical to provide sufficient force to secure the weight plate to the bracket.

In some embodiments, the latch engagement angle and the notch engagement angle are complementary. In other words, the latch engagement angle and the notch engagement angle add up to 180°. Complementary latch and notch engagement angles can increase the bearing surface between the latch and notch engagement surfaces. This increases the force securing the weight plate to the bracket. In some embodiments, the latch engagement angle and the notch engagement angle are not complementary and may add up to an angle greater or less than 180°.

In some embodiments, the latch has a complementary cross-sectional shape to the notch. Accordingly, when actuated, the latch may insert into the notch and provide resistance to prevent removal of non-selected weight plates from the bracket. In some embodiments, the latch has a cross-sectional shape that is not complementary to the notch.

In some embodiments, the latch can be located on one side of the adjustable dumbbell. In this manner, the latch may be configured to connect to the notch on the side or top surface of the weight plate. In some embodiments, the latches on the side of the adjustable dumbbell may directly engage the top surface, rather than a notch in the top surface, to secure the weight plate to the bracket. This may allow the retention system to secure the weight plate to the bracket. also, The retention system on the side of the adjustable dumbbell may allow the user to visually confirm that the latch is engaged with the weight plate.

In some embodiments, the latch can be located under the adjustable dumbbell. In this manner, the latches may be configured to insert into cavities in the carrier surface of the weight plate and engage notches located in the cavities. This may allow the weight plate to be secured to the bracket and may prevent user tampering with the retention mechanism.

In some embodiments, a retention mechanism in the bracket can exert a force on the latch to insert and remove the latch from the slot. For example, the retention mechanism may include a retention camshaft that includes a plurality of lobes. The lobes can be spaced longitudinally along the retaining shaft and aligned with the latch arms on the latch. When the lug pushes the latch arm, the protrusion on the latch can move relative to the notch. Each latch may include a resilient member that pushes the latch in a direction opposite to the direction in which the lobe pushes the latch arm (eg, toward or away from the notch). The elastic members may include coil springs, torsion springs, wave springs, elastic foam, elastically deformable materials, any other elastic members, and combinations of the foregoing.

In some embodiments, the protrusion can move into the notch when the lobes on the retaining camshaft push the latch arm. In some embodiments, the protrusion can move away from the notch when the lobes on the retaining camshaft push the latch arm. In some embodiments, the latch arm may include a pivot. When the lobes on the retaining camshaft push the latch arm, the latch arm can rotate about the pivot. So when keeping the camshaft on the dumbbell side of the latch, the protrusion can move into the notch when the lobe pushes on the latch arm. When holding the camshaft opposite the dumbbell across the latch, the protrusion can move away from the notch as the lobes push the latch arm.

In some embodiments, the latch can translate (eg, not rotate, move laterally toward/away) relative to the weight plate. So when keeping the camshaft on the dumbbell side of the latch, the protrusion can move away from the notch when the lobes push the latch. When holding the camshaft across the latch against the dumbbell, the protrusion moves toward the notch as the lobes push the latch.

In some embodiments, the latch may be located below the carrier surface of the weight plate. When the adjustable dumbbell is placed on the carriage, the latches extend into cavities in the surface of the weight plate carriage. The latch may comprise two rotary latch members. In the latch up position, the cavity member in the cavity may push the rotating latch member into the notch in the cavity, thereby securing the weight plate to the bracket. In the latch down position, the rotary latch member may not contact the cavity member, and the rotary latch member will not insert into the notch, allowing the weight plate to be removed from the bracket. In some embodiments, the retaining camshaft may be located below the latch. Holding the lobes on the camshaft pushes the latch into the upper position.

In some embodiments, the weight plate may include a base notch in a notch of the base. The latch may extend up into a cavity in the weight plate. The latch is movable laterally (eg, vertically toward and away from the floor notch) until the latch engages the floor notch. In this way, the latch can move horizontally to secure the weight plate to the carriage.

In some embodiments, the retention mechanism can move the latch toward or away from the slot, and can include any retention mechanism, including camshafts, solenoids, linear motors, piezoelectric materials, other linear motion devices, and combinations of these . In some embodiments, the retention mechanism may include lobes on the camshaft that selectively and individually engage or actuate the latch. exist In some embodiments, the camshaft can actuate a single latch at a time. In some embodiments, the camshaft can actuate more than one latch at a time. In some embodiments, the camshaft can actuate all latches at once. In some embodiments, the camshaft may include multiple lobes on the same circumference, which may actuate the latch at different rotational positions. In this way, the camshaft can actuate different combinations of latches depending on the combination of selected and unselected weight plates. In some embodiments, multiple latches may use the same camshaft. In some embodiments, all latches may use the same camshaft. In some embodiments, multiple camshafts can actuate multiple latches. In some embodiments, each latch may be located on the same side of the weight plate. In some embodiments, at least one latch can be located on a first side of the weight plate and at least one latch can be located on a second side of the weight plate.

In some embodiments, as described above, the weight plate may be selected and attached to the handle using plate protrusions extending from the plate receptacle into cavities in the weight plate. Additionally, as mentioned above, the latch may protrude from the board container. Thus, each weight plate may have two protrusions extending into the weight plate. In some embodiments, the plate protrusion and the latch may extend into the same cavity in the weight plate. In some embodiments, the plate protrusions and latches may extend into different cavities in the weight plate. In some embodiments, the plate protrusion and the latch can be actuated by the same retention mechanism. For example, the plate protrusion and the latch may be actuated using the same camshaft, with lobes on the camshaft configured to actuate both the plate protrusion and the latch. In some embodiments, the plate protrusions and latches can be actuated by different retention mechanisms. For example, a plate protrusion may be actuated by a plate camshaft and a latch may be actuated by a latch camshaft.

In some embodiments, the weight plate may include a plate latch and the bracket may include a bracket notch. A protrusion may extend upwardly from the plate receptacle and into the cavity of the weight plate. In the upper position, the protrusions may push one or more board latches laterally outward. One or more board latches may extend into the bracket notch. Thus, when the adjustable dumbbell is removed, non-selected weight plates can be secured to the bracket with the plate latch inserted into the bracket notch. In some embodiments, a retaining mechanism may be positioned below the latch and move the latch between an up position and a down position. In some embodiments, the weight plate may include plate latches and notches, and the bracket may include latches and bracket notches. This provides additional strength to the contact between the weight plate and the bracket, thus providing additional protection against the weight plate being removed from the bracket.

In some embodiments, each latch of the plurality of latches may have an associated retention mechanism. This can allow many different combinations of engaging the latches, and thus the weight plates secured to the brackets. This can increase the versatility of the adjustable dumbbell, thereby improving the user experience. In some embodiments, multiple latches may use the same retention mechanism. This can simplify the bracket assembly, which can improve reliability and reduce manufacturing costs.

In some embodiments, the plate adjustment mechanism may be mechanically connected to the retention mechanism. In this manner, unselected weight plates can be automatically secured to the bracket when the selected weight plate is attached to the handle or bar mount. For example, an adjustable dumbbell can include at least two weight plates. The user can select the desired weight of the adjustable dumbbell through a weight selection input on the bracket, dumbbell, handle, or other location. A user may cause the plate adjustment mechanism to select a first weight and connect it to the handle. Retention can be enabled mechanically using the plate adjustment mechanism mechanism, which secures non-selected weight plates to the brackets. In at least one embodiment, mechanically coupling the plate adjustment mechanism to the retention mechanism can simplify the use of adjustable dumbbells by allowing the user to focus on selecting and using the desired weight plate without worrying about securing non-selected weight plates Or worry about safety hazards posed by unselected weight plates.

In some embodiments, the plate adjustment mechanism may include a combination camshaft to connect the weight plate to the handle, and the retention mechanism uses the same combination camshaft to engage a latch in a slot in the weight plate to secure the weight plate onto the handle. In some embodiments, the plate adjustment mechanism may include a plate camshaft in the handle of the adjustable dumbbell. The plate camshaft can be rotated by means of a plate gear on the main shaft. The latch camshaft selectively engages the latch with the weight plate. The latch camshaft can be rotated through the latch gear. In some embodiments, the latch gear may be on the same spindle as the plate gear. In some embodiments, the latch gear may be located on a countershaft connected to the mainshaft through a gear connection. Additionally, this can help prevent incorrectly securing a non-selected weight plate to the bracket. Taking it a step further, this can help prevent mistaken failure to secure a non-selected weight plate, which could then be misplaced or become a safety hazard.

In some embodiments, the bracket may include a weight plate receptacle, a plate adjustment mechanism, and a retention mechanism sufficient to operate a single adjustable dumbbell. In some embodiments, the bracket may include a weight plate receptacle sufficient to operate a single adjustable dumbbell, a plate adjustment mechanism, and a retention mechanism. In some embodiments, the plate adjustment mechanism and retention mechanism for a plurality of adjustable dumbbells may be operated by the same driving force, such as a spindle. This may simplify the dumbbell adjustment process for the user. this Also, this helps prevent incorrectly securing a non-selected weight plate to the bracket. Taking it a step further, this can help prevent mistaken failure to secure a non-selected weight plate, which could then be misplaced or become a safety hazard.

In some embodiments, a method for securing an adjustable dumbbell includes placing a dumbbell handle in a bracket. The dumbbell handles are selectively connectable to one or more selected weight plates of the plurality of weight plates. One or more unselected weight plates may be secured to the bracket, based on which weight plates are selected for attachment to the dumbbell handles. Securing the non-selected weight plates to the bracket may include inserting a latch on the bracket into a notch of the non-selected weight plate. Securing an unselected weight plate to the bracket may also include inserting a protrusion into a cavity of the unselected weight plate, the protrusion including a latch coupled to a notch in the cavity.

The method may further include selecting the selected weight plate and identifying the unselected weight plate as any weight plate of the plurality of weight plates that is not the selected weight plate. In other words, the total number of weight plates can be divided into selected weight plates that are connected or attached to the dumbbell handles and unselected weight plates that are secured to the bracket.

In some embodiments, the adjustable dumbbell may include a rack and pinion plate adjustment mechanism. A motor may be located in the bracket, and a shaft may extend through the bracket and connect to the gearbox. The gearbox may include pinions. The handle can be hollow and include an extension arm. A rack (eg, a linear gear) may be located inside the hollow handle. A rack can be connected to a pinion. As the pinion rotates, the rack can extend the extension arm. Each weight plate may include a void through which the extension arm may extend. The extension length of the extension arm can determine the number of weight plates selected and thus the total weight of the adjustable dumbbell. The motor can also be connected to a holding mechanism consisting of a rack and pinion in a The latch arm can be extended. The latch arms may engage/disengage the latches with notches on the weight plates corresponding to selected and unselected weight plates. Thus, the plate adjustment mechanism and the holding mechanism may be connected through a gear connection.

In some embodiments, the bracket supports a plurality of weight plates and handles. The handle includes a plate adjustment mechanism that selectively connects the weight plate to the handle. The plate adjustment mechanism is driven by a motor under the carriage.

A motor under the carriage controls the plate adjustment mechanism. The motor rotates the first gear shaft and the second gear shaft. The first gear shaft and the second gear shaft are connected through a plate gear belt. Therefore, the first gear shaft and the second gear shaft can rotate at the same speed.

The plate adjustment mechanism includes a first gear shaft and a second gear shaft. The first gear shaft and the second gear shaft are driven by a motor. The first pinion is connected to the first gear shaft, and the second pinion is connected to the second gear shaft. The first pinion drives a first rack on the first plate extension and the second pinion drives a second rack on the second plate extension.

The first plate extension rod and the second plate extension rod extend into a series of voids in the weight plate. The extension lengths of the first plate extension and the second plate extension determine the number of weight plates attached to the handle. In this way, by rotating the first gear shaft and the second gear shaft, the weight plate can be selected.

The adjustable dumbbell assembly includes a plate adjustment mechanism in the handle and a retention mechanism in the bracket. The plate adjustment mechanism and the holding mechanism are driven by the same mechanism. Specifically, the first gear shaft drives the first plate extension rod and the first retainer extension rod, and the second plate gear shaft drives the second plate extension rod and the second retainer extension rod. Thus, the plate adjustment mechanism may be mechanically coupled with the retaining mechanism. In other words, When the plate adjustment mechanism connects the weight plate to the handle, the retaining mechanism may, in conjunction with the same operation of the motor, secure one or more unselected weight plates to the bracket.

The bracket includes a retention mechanism slot. As the first gear shaft rotates, a first retention pinion (not shown) on the first gear shaft may engage a first retention rack on the first retention extension. This can cause the first retention extension to extend into the retention mechanism slot where it can engage one or more latches. One or more latches may engage one or more unselected weight plates, securing them to the carrier. Similarly, a second retaining pinion on the second pinion shaft may engage a second retaining rack on the second retaining extension as the second pinion shaft rotates. This can cause the second retention extension to extend into the retention mechanism slot where it can engage one or more latches. One or more latches may engage one or more unselected weight plates, securing them to the carrier.

In some embodiments, each weight plate may be connected to each other via an interlocking connection. For example, in the illustrated embodiment, the interlocking connection may allow the weight plates to be separated from each other using an upward force, but may prevent separation from each other using a downward or longitudinal force (eg, parallel to the handle). In some embodiments, the interlock connection may be a dovetail connection. In some embodiments, the interlock connection can be any type of interlock connection.

Interlocking connections can help keep all non-selected weight plates oriented in the same direction. In this manner, the handle and selected weight plates can be removed from the carrier, and all non-selected weight plates can remain upright in the carrier. This may allow the handle and selected weight plate to be easily reinserted into the carrier without having to align non-selected weight plates in the carrier.

In some embodiments, the retention mechanism may include retention protrusions at either end of the bracket. The retaining protrusions may extend into the end weight plates. End weight plates can be connected to other weight plates through interlocking connections. Thus, when the handle is removed, the end weight plates may remain fixed to the bracket, and the remaining non-selected weight plates may remain oriented relative to the end weight plates via the interlocking connections. Thus, the end weight plates may be the only weight plates secured to the bracket, and the remaining weight plates may remain upright based on the interlocking connection with the end weight plates.

In some embodiments, the retention protrusion may be rigidly attached to the bracket. For example, the retention protrusion may have a height and/or position relative to the bracket that does not change based on actuation of the plate adjustment mechanism. In some embodiments, the retaining protrusion can be actuated. For example, the retention protrusion may have an adjustable height and may only extend into the end weight plate when the retention mechanism engages the retention protrusion. In other examples, the end weight plates may be secured to the bracket using latches on the sides of the end weight plates or any other mechanism described herein.
