专利说明:

[0001] The disclosure relates to fitness equipment, more particularly to a dumbbell set with adjustable weights.
[0002] The dumbbell is exercise equipment for training the hand muscles and is usually equipped with a single weight that cannot be changed. If a user needs to set different exercise intensity, he should prepare many dumbbells of different weights at the same time. This not only leads to waste of money, but also storage difficulties.
[0003] A dumbbell set is disclosed in Taiwanese Patent Application No. TW201725062, and mainly comprises a base seat and a dumbbell. The dumbbell has a handle and two weight units arranged respectively on two opposite ends of the handle. Each weight unit has a plurality of hook discs rotatable in conjunction with the handle, and a plurality of weight blocks. Each hook disc has a hooking unit that has at least one protruding part and at least one spacer in addition to the at least one protruding part. Each weight block has a hooking protrusion. The rotation of the handle makes it possible to adjust the relative position between the at least one protruding part and the at least one spacing of the hook discs and the hooking protrusion, so that the weight blocks can be mounted selectively on the handle or detached from the handle so as to be placed in the receiving seat, thereby achieving the effect of adjusting the weights of the dumbbell.
[0004] Although the aforementioned dumbbell assembly can achieve its intended purpose, since each weight block is connected to a corresponding disc of the hook discs through its hooking protrusion, the weight of the weight block is therefore concentrated on the protrusion of hook, and since the hook protrusion is not integrally connected to the main body of the weight block, if there are defects during the manufacture of the hook protrusion and the main body of the weight block, the hooking protrusion easily breaks off and is removed from the main body of the weight block. If the break occurs during exercise, the weight block will fall straight down and potential danger may arise.
[0005] Accordingly, an object of the present disclosure is to provide a dumbbell assembly which is capable of overcoming at least one of the drawbacks of the prior art.
[0006] According to this disclosure, a dumbbell assembly includes a base seat extending along a left-right direction, two weight units, and a dumbbell. The base seat has a main seat body having two receiving areas formed in an upper surface thereof and spaced apart from each other in the left-right direction. Each receiving area has a plurality of receiving grooves arranged spaced apart from each other along the left-right direction. The weight units are respectively arranged in the receiving areas. Each weight unit has a plurality of weight blocks received respectively and removably in the receiving grooves of a respective one of the receiving areas. Each weight block has at least one engagement hole.
[0007] The dumbbell has a handle extending in the left-right direction and two weight adjustment modules respectively arranged on two opposite ends of the handle and respectively corresponding to the weight units. Each weight adjustment module has an insertion base defining a plurality of adjustment spaces arranged spaced apart from each other along the left-right direction, and a plurality of engagement units respectively received in the adjustment spaces and corresponding respectively to the weight blocks of a respective weight unit. Each engagement unit includes a drive component mounted on the handle, and at least one insertion pin resiliently connected to the drive component and corresponding to the at least one engagement hole. As the handle is rotated relative to the weight adjustment modules, the handle drives each engagement unit to move between an engaged state and a disengaged state.
[0008] When each engagement unit is in the engagement state, the at least one insertion pin is driven by the drive component to protrude out of the insertion base and engage in the au at least one engagement hole in a corresponding block of weight blocks, thereby connecting the insertion base to the corresponding weight block; and, when each engagement unit is in the disengaged state, the at least one insertion pin is retracted into the insertion base and is moved away from the at least one engagement hole in the corresponding block weight blocks, thereby detaching the insert base from the corresponding weight block.

[0038] Referring to Figures 1 to 3, it is seen that a dumbbell assembly according to one embodiment of the present disclosure comprises a base seat 1, two weight units 2 and a dumbbell 3.
[0039] The base seat 1 extends along a left-right (X) direction and has a main seat body 11 and two projections 13 protruding from the main seat body 11. The main seat body 11 has two receiving areas 12 formed in an upper surface thereof and spaced from each other in the left-right (X) direction. Each receiving area 12 has three receiving grooves 121 arranged spaced apart from each other along the left-right (X) direction. The projections 13 are located between the landing areas 12. Specifically, each projection 13 is close to a respective area of the landing areas 12, and has an inverted L-shaped body.
[0040] The weight units 2 are respectively arranged in the receiving areas 12. Each weight unit 2 comprises three weight blocks 2 received respectively and removably received in the receiving grooves 121 of a respective area of the receiving areas 12. Each weight block 21 has a substantially U-shaped groove wall 211 defining an insertion groove 20 with an upwardly facing opening, and two engagement holes 212 (only one is visible in Figure 2) formed in two opposite ends of the groove wall 211 near an upper end thereof and spaced apart from each other along a front-back direction (Y) transverse to the left-right direction (X ). The weight blocks 21 of each weight unit 2 have different thicknesses and weights. The outermost block of the 21 weight blocks is the thinnest and lightest, while the innermost block of the 21 weight blocks is the thickest and heaviest.
[0041] The dumbbell 3 has a handle 31, two weight adjustment modules 32 and two anti-rotation modules 33. The handle 31 extends in the left-right (X) direction and has a grip part 311 and a grip part 311. shaft 312 extending through the gripping part 311. The weight adjustment modules 32 are respectively mounted on two opposite ends of the shaft part 312. The anti-rotation modules 33 are respectively connected to the weight 32.
[0042] Each weight adjustment module 32 has a hollow insertion base 321, four substantially U-shaped limitation plates 322 disposed on a lower part of the insertion base 321 and spaced apart from each other along the left direction -right (X), three engagement units 323, 323', 323'', an upper cover 324 and three first elastic elements 325. Each of the two adjacent limiting plates 322 cooperates with the lower part of the insertion base 321 to define a mounting space 302. Thus, the lower part of the insertion base 321 and the limit plates 322 cooperatively define three mounting spaces 302 spaced along the left-right (X) direction. The insertion base 321 of each weight setting module 32 can be inserted into the insertion grooves 20 of the weight blocks 21 of the corresponding weight unit 2, so that the weight blocks 21 are respectively received in the mounting spaces 302. The insertion base 321 defines three setting spaces 301 arranged to be spaced from each other along the left-right (X) direction and respectively having openings facing upwards.
[0043] The engagement units 323, 323', 323'' of each weight setting module 32 are respectively disposed in the setting spaces 301 of the insertion base 321, and respectively correspond to the weight blocks 21 of each weight unit. weight 2. Each engagement unit 323, 323', 323'' has a drive component 400 mounted on the shaft portion 312 of the handle 31, two insertion pins 500 respectively connected to the front and rear sides of the drive component 400, and two second elastic elements 600 respectively fitted onto the insertion pins 500. The drive component 400 of each engagement unit 323, 323', 323'' has a drive block 41, 41', 41'' fitted onto one of the ends of the shaft part 312 and driven in rotation by the handle 31, and a driven block 42 superimposed on the drive block 41, 41', 41'' and up against it. Driven block 42 is driven to move up and down relative to drive block 41, 41', 41'' when the latter is rotated by handle 31. For illustrative purposes, the drive component drive block 400 of the engagement unit 323 which is close to the grip portion 311 is represented by reference numeral 41, the drive component drive block 400 of the 'Engagement unit 323'' which is distal to grip portion 311 is represented by reference numeral 41'', and drive component drive block 400 of engagement unit 323 ' which is disposed between the engagement units 323 and 323'' is represented by the reference numeral 41'.
[0044] Referring to Figures 4 to 7, the drive blocks 41, 41', 41'' of the engagement units 323, 323', 323'' have different shapes. The drive block 41, as shown in Figure 5, has a substantially sector-shaped drive main body 411, five spaced projecting portions 412 projecting outwardly and integrally from an outer periphery of the driving main body 411, and four positioning recesses 413 extending inward from the outer periphery thereof and each of which is located between two adjacent portions of the projecting portions 412. The drive block 41', as shown in Figure 6, has a substantially rectangular drive main body 411', three projecting portions 412' projecting outward and integral from each short side of the drive main body 411', and four positioning recesses 413' each of which is located between two adjacent parts of the projections 412'. The drive block 41'', as shown in Figure 7, has a body main drive 411' ' X-shaped having four spaced apart arms 4111, four pairs of protrusions 412'' each pair of which projects outwardly and integrally from a respective arm of the arms 4111, and four recesses of positioning 413'' each of which is located between a respective pair of the pairs of protrusions 412''.
[0045] Figure 8 illustrates the drive blocks 41, 41', 41'' of the engagement units 323, 323', 323'' which are sleeved on the rod portion 312 of the handle 31 and overlap in the left direction -right (X) (see Figures 1 and 2) with the projecting parts 412, 412', 412'' of the drive blocks 41, 41', 41' blocking each other.
[0046] Referring again to Figures 4 through 7, the driven block 42 of each engagement unit 323, 323', 323'' has a driven main body 421 and a downwardly projecting abutment portion 422 and a standing alone from the main driven body 421 and abutting against the drive block 41, 41', 41'' of a corresponding unit of the engagement units 323, 323', 323''. The driven main body 421 has two curved guide notches 423 opposite to each other in the front-back (Y) direction. Each guide notch 423 is defined by a notch defining surface 4231.
[0047] Referring to Figures 3-7, the insertion pins 500 of each engagement unit 323, 323', 323'' are located in a corresponding space of the adjustment spaces 301. Each insertion pin 500 has a portion curved head portion 52 abutting the surface defining a notch 4231 of a respective one of the guide notches 423, and a stem portion 51 extending outwardly from the head portion 52 along the front-back direction (Y) and inserted into the insertion base 321 to position it there. The second elastic elements 600 of each engagement unit 323, 323', 323'' are respectively fitted onto the stem parts 51 of the insertion pins 500. Each second elastic element 600 comes into abutment between the head part 52 and the insert base 321.
[0048] The top cover 324 is mounted on the insertion base 321 and covers the adjustment spaces 301. Each first elastic member 325 is disposed between the top cover 324 and one of the driven blocks 42 of the engagement units 323, 323' , 323'', and elastically urges one of the driven blocks 42 downwards.
[0049] Referring to Figure 12, in combination with Figure 7, the 323” engagement unit will be illustrated below. The engagement unit 323'' can be driven by rotation of the handle 31 to move between an engaged state and a disengaged state. When the engagement unit 323'' is moved from the disengagement state (see Figure 7) to the engagement state (see Figure 12), the drive block 41'' rotates with one of the arm 4111 pushing up the abutment part 422 of the driven block 42 until the abutment part 422 moves over one of the projections 412'' and falls into the positioning recess 413'' and engages therewith, thereby driving the driven main body 421 to move upward relative to the insertion base 321 and relative to the insertion pins 500. At this time, the insertion pins 500 are spaced away from the respective guide notches 423 and are urged by the notch-defining surfaces 4231 of the guide notches 423 to move until the stem portions 51 thereof protrude out of the insertion base 321 and engage the respective engagement holes 212 of the weight block 21, thereby connecting the insertion base 321 to the weight block 21. Simultaneously, the first elastic member 325 is compressed by the driven main body 421 to store a restoring force, and presses down on the abutment portion 422 to abut against the positioning recess 413 and preventing it from slipping therefrom, thereby fixing the engagement unit 323'' in the engagement state. The second elastic members 600 are compressed due to the outward movement of the insertion pins 500 and store restoring forces.
[0050] To change the engagement unit 323'' from the engagement state to the disengagement state, the handle 31 is turned to cause the rotation of the drive block 41'' with respect to the driven block 42 in order to to cause the abutment part 422 to come out of the positioning recess 413'' and to cause it to move on one of the projecting parts 412'' to a position between two adjacent arms of the arms 4111. At this moment , the upward biasing force on the driven block 42 is released, and the biasing force of the first elastic member 325 is also released and urges the driven block 42 to move downward relative to the insertion pins 500 to fix the engagement unit 323'' in the disengagement state. At the same time, the biasing forces of the second elastic members 600 are also released and respectively urge the head portions 52 of the insertion pins 500 to move into the respective guide notches 423 and gradually retract the shank portions 51 of the pins. 500 into the insertion base 321 and away from the respective engagement holes 212 of the weight block 21, thereby detaching the insertion base 321 from the weight block 21.
[0051] Since the relative positions of the drive blocks 41, 41', 41'' are fixed, when the drive blocks 41, 41', 41'' are rotated by the handle 31, specific areas of the blocks 41, 41', 41'' can be selected to be directed upwards in a state in which the projecting parts 412, 412', 412'' can interact with the abutment parts 422 of the driven blocks 42. As such, the engage units 323 can be respectively and independently switched between the engage state and the disengage state.
[0052] Referring again to Figures 2 and 3, the anti-rotation modules 33 are mounted on the two opposite ends of the shaft portion 312 of the handle 31, and respectively face the weight adjustment modules 32. Each module anti-rotation 33 has an outer casing 331, and a rotatable disk 332 fixed in rotation to the outer casing 331. Before the insertion base 321 of each weight adjustment module 32 of the dumbbell 3 is inserted into the grooves inserting 20 the weight blocks 21 of the corresponding weight unit 2, the anti-rotation modules 33 can prevent rotation of the handle 31 relative to the weight adjustment modules 32; and, after the insertion base 321 of each weight adjustment module 32 of the dumbbell 3 is inserted into the insertion grooves 20 of the weight blocks 21 of the corresponding weight unit 2, the anti- rotation 33 are activated by the respective projections 13 so as to allow the rotation of the rotating disc 332 and the handle 31 with respect to the weight adjustment modules 32 to switch the states of the engagement units 323, 323', 323'' . Since the anti-rotation modules 33 are not the main aspect of this disclosure, a detailed description of them will be omitted here.
[0053] Referring to Figures 1 and 2, to use this embodiment, the weight units 2 are first placed in the receiving areas 12, after which the insertion bases 321 of the weight adjustment modules 32 of the dumbbell 3 are inserted downward into the insertion grooves 20 of the weight blocks 21 so as to be arranged in a state shown in Fig. 1. At this time, the projections 13 of the base seat 1 respectively activate the modules anti-rotation 33, so that the user can turn the handle 31 relative to the weight adjustment modules 32.
[0054] Referring to Figures 4-7, when the user intends to use the lightest weight, i.e., the dumbbell 3 is not connected to any of the weight blocks 21 , the user turns the grip portion 311 of the handle 31 to adjust the drive main body 411, 411', 411'' so that its projecting portions 412, 412', 412'' are not directed towards the top, so that all the engagement units 323, 323', 323'' are in the disengagement state. When the user lifts the handle 31, all the weight blocks 21 are not connected to the weight adjustment modules 32 and all remain in the respective receiving grooves 121, so that the user can obtain the lightest weight of dumbbell 3.
[0055] Referring to Figures 9 through 12, if the user intends to change the weight, for example, he intends to connect only the outermost weight blocks 21 of the weight units 2 to To achieve the second lightest weight, the dumbbell assembly of this disclosure is first returned to the condition shown in Fig. 1, after which the grip portion 311 of the handle 31 is rotated to move one of the pairs projecting portions 412'' of the drive blocks 41'' to be directed upward, and only the outermost engagement units 323'' enter the engagement state, while the other engage units 323 and 323' remain in the disengage state. After adjustment, when the user lifts the handle 31, he can get the desired weight from the outermost weight blocks 21.
[0056] Referring to Figures 13 to 16, the handle 31 is rotated to adjust the projections 412' on one of the short sides of the main drive bodies 411' of the drive blocks 41' to face upwards. , so that only the middle blocks of the weight blocks 21 can be connected to the weight adjustment modules 32, or referring to Figures 17 to 20, only the innermost blocks of the weight blocks 21 can be connected to the weight adjustment modules 32, so that different weight effects can be achieved by connecting to different weight blocks 21.
[0057] Referring to Figures 21 to 24, similarly, by rotating the grip portion 311 of the handle 31, the middle engagement units 323' and the innermost engagement units 323 can simultaneously pass in the engagement state, while the outermost engagement units 323'' go into the disengagement state, so that each weight adjustment module 32 is connected to two weight blocks 21 , thus obtaining a heavier weight. Of course, the gripping part 311 of the handle 31 can be rotated so that only the outermost engagement units 323'' and the middle engagement units 323' simultaneously enter the state of being engaged. engagement, or only the outermost engagement units 323'' and the innermost engagement units 323 enter the engagement state simultaneously, so that different combinations of two weight blocks 21 connected to the weight adjustment modules 32 can be obtained.
[0058] Referring to Figures 25 to 28, the grip portion 311 of the handle 31 is rotated so that specific projecting portions 412, 412', 412'' of the driving main body 411, 411', 411'' are directed upwards, so that the engagement units 323, 323', 323'' all enter the engagement state, and all the weight blocks 21 are connected to the weight adjustment modules 32, thus obtaining the heaviest weight of the dumbbell 3.
[0059] It should be mentioned here that, in this embodiment, the weight blocks 21 of each weight unit 2 have different widths in the left-right (X) direction and different weights. The widths of the receiving grooves 121 corresponding to the weight blocks 21 are also changed accordingly. However, in practice, it is not limited to this. The sizes of the weight blocks 21 and the receiving grooves 121 can be the same and will not affect the effect of the weight adjustment. In addition, the number of 21 weight blocks of each 2 weight unit is not limited to three, it can be two or four. Match the number corresponding to the engaging units 323, 323', 323'' and set the number of the projecting parts 412, 412', 412'' of the driving blocks 41, 41', 41'' and the structures overlapping and non-overlapping portions also achieves the effect of weight adjustment.
[0060] It should be noted here that, each weight block 21 has two engagement holes 212, and each engagement unit 323, 323', 323'' has two insertion pins 500 insertable into the engagement holes. 212 in the front-rear (Y) direction, in addition to providing a more stable connection, the balance of the overall structure can also be maintained. However, in practice, it is not limited to this. In other variations of this embodiment, each weight block 21 may have a single engagement hole 212, and each engagement unit 323, 323', 323'' may have a single insertion pin 500 that can be inserted into the engagement hole 212. The linking effect between the weight adjustment module 32 and the weight block 21 can still be obtained.
[0061] In sum, the effect of the dumbbell assembly of this disclosure resides in the following: by the structural design of the protrusions 412, 412', 412'' of the drive blocks 41, 41', 41'', all or part of the engagement units 323, 323', 323'' can be driven to the engagement state or the disengagement state so as to facilitate the user's selection of different weight of the weight blocks 21, thus achieving the purpose of adjusting the weight of the dumbbell 3. Further, the connection of each engagement unit 323, 323', 323'' with each weight block 21 is achieved by inserting the insertion pins 500 into the engagement holes 212 of the weight block 21, replacing the existing weight block which requires additional connection with a hooking protrusion before it can be connected to the dumbbell, and avoiding the situation where the hooking protrusion can break off and the weight block can come off. In addition, each weight block 21 is connected to two insertion pins 500, so even if one of the insertion pins 500 is broken, the weight block 21 will not immediately fall to the ground. A new 500 insert pin replaces the broken one, and it is not necessary to replace the entire 21 weight block. Not only the 32 weight adjustment modules and the 21 weight blocks can be securely connected to each other, but also the maintenance cost can be greatly reduced.
