Detailed Description

The present invention relates to an adjustable exercise and fitness device or dumbbell, please refer to fig. 1-4, the whole pair of adjustable exercise and fitness device mainly includes a base 10 having one or more, for example, four or more, accommodating slots 11 for receiving or accommodating one or two dumbbells, for example, four groups of weight bodies 20,21,30,31 of a first dumbbell 2 and a second dumbbell 3, the base 10 having one or more, for example, four pockets 12,13,14,15 disposed or formed between the accommodating slots 11 (fig. 2, 3) of the base 10 and/or disposed or formed between the four groups of weight bodies 20,21,30,31 and communicated with the accommodating slots 11, the base 10 further having one or more, for example, four channels 16 communicated with the weight pockets 12,13,14,15, respectively.

The dumbbells 2,3 each have a central handle 4,5 for mounting or positioning between the four sets of weights 20,21,30,31, e.g., the first handle 4 and the second handle 5 each have a central grip 40,50 and each have two housings 41,42,51,52 mounted or positioned on the end portions of the grips 40, 50. The housings 41,42,51,52 each have a cavity 43,53 for receiving or housing, for example, first and second weight plates 60,61 and first and second weight plates 62,63, wherein each housing 41,42,51,52 has a partition or frame 44 (fig. 6, 7) disposed within its cavity 43,53 and one or more, for example, two apertures 45 formed or disposed within each frame 44.

One or more, for example four, pegs 47 (fig. 2) are slidably disposed within the handle 40,50, respectively, and are configured to protrude from the housing 41,42,51,52, so that a different or predetermined number of weight bodies 20,21,30,31 can be coupled to the handle 40,50 and/or the housing 41,42,51,52 of the grip 4, 5. The structure or technical idea of the plug 47 for connecting the weight bodies 20,21,30,31 to the grip bars 40,50 and/or the shells 41,42,51,52 of the grips 4,5 is prior art and will not be described herein.

As shown in fig. 2,6-7, the first and second weight plates 60,61 and the first and second weight plates 62,63 each have a space 64, and each have one or more, e.g., two, through-slots 65 formed therein and communicating with the space 64 thereof, and each have one or more, e.g., two, chambers 66 formed therein and communicating with the through-slots 65 thereof, and wherein intermediate portions of the chambers 66 of each of the weight plates 60,61 and the weight plates 62,63 are in communication with each other so as to form an opening 67.

A pair of resilient fasteners 70 are slidably disposed in the through-slots 65 of each of the weight plates 60,61 and weight plates 62,63 and are configured to resiliently protrude into the space 64 of each of the weight plates 60,61 and weight plates 62,63, and two lever arms 71 are slidably disposed in the chambers 66 of each of the weight plates 60,61 and weight plates 62,63 and are coupled at first ends 72 to the fasteners 70 to control the operation of the fasteners 70 into and out of the space 64 (FIGS. 6, 7) of each of the weight plates 60,61 and weight plates 62, 63. The other or second end 73 of lever arm 71 is received or disposed within opening 67 of each of the weight plates 60,61 and weight plates 62, 63.

As shown in FIG. 7, when second end 73 of lever arm 71 is pushed up into chamber 66 of weight plates 60,61 and weight plates 62,63, lever arm 71 forces fastener 70 out of space 64 of weight plates 60,61 and weight plates 62,63 and into slot 65 of weight plates 60,61 and weight plates 62, 63. Conversely, when second end 73 of lever arm 71 is released from being pushed up into pockets 66 of weight plates 60,61 and weight plates 62,63, as shown in FIG. 6, resilient catch 70 will be resiliently forced to protrude into space 64 of weight plates 60,61 and weight plates 62, 63.

As shown in fig. 3-4,6-7 and 9-11, a support plate or block 80 is slidably disposed within the base 10, and has one or more, such as four, protrusions 81 and one or more, such as four, protrusions 82, respectively, protruding through the channel 16 of the base 10 into the cavities 12,13,14,15 of the base 10 so as to touch or touch the second end 73 of the lever arm 71 (fig. 7), and at least one resilient member 83 is disposed between the base 10 and the block 80 so as to urge the protrusions 81 and 82 to protrude into the cavities 12,13,14,15 of the base 10, wherein preferably, the protrusions 81 are higher than, but not necessarily, the protrusions 82. The support block 80 is further provided with one or more, e.g. three, protrusions 84 projecting upwardly and preferably, but not necessarily, enclosing a loop, wherein each protrusion 84 has one or more, e.g. two, seats or shoulders 85,86.

A drive member 90 is rotatably disposed within housing 10 and is adapted to contact or bear against protrusions 84 or shoulders 85,86 of support block 80. As shown in fig. 3, the channel 16 and the recess 11 of the housing 10 and the cavities 12,13,14,15 are disposed or formed in a top plate 17 thereof, and one or more, for example, three grooves 18 are also disposed or formed in the top plate 17, wherein the driving member 90 has one or more, for example, three locking members 91 protruding upward and slidably disposed in the grooves 18 of the top plate 17 of the housing 10 so as to limit the rotational movement of the driving member 90 relative to the housing 10. A torque or torsion body 92 is coupled to the clamp body 91 to rotatably couple the driving member 90 to the housing 10 so that the driving member 90 can be driven to rotate relative to the housing 10. The driving member 90 has one or more, for example three, inserts 93 for engaging or contacting or abutting against the protrusions 84 or shoulders 85,86 of the support block 80 (fig. 12-14).

In the operation of the present invention, referring to fig. 8-9 and 12, when the insert 93 of the driving member 90 is separated from the protrusion 84 of the support block 80, the protrusion rod 81 and the protrusion 82 of the support block 80 can be forced to touch or abut against the second end 73 of the lever arm 71 to force the fastening member 70 to be separated from the spaces 64 of the weight plates 60,61 and the weight plates 62,63 and to be retracted into the through-groove 65. At this time, as shown in FIG. 7, when the fasteners 70 are retracted into the through-slots 65 of the weight plates 60,61 and weight plates 62,63, they can be separated from the frame 44 of the housing 41,42,51,52, so that the weight plates 60,61 and weight plates 62,63 are not coupled or bonded to the housing 41,42,51,52 (FIG. 9) of the grip 4, 5.

As shown in FIGS. 10 and 13, when the insert 93 of the driving member 90 is forced against or against the protrusion 84 of the support block 80, such as the first shoulder 85, the support block 80 is forced downward to separate the weight plate 61 and the weight plate 63, such that the weight plate 61 and the weight plate 63 can be coupled or bonded to the housing 41,42,51,52 (FIG. 10) of the grip 4, 5. As shown in FIGS. 11 and 14, when the insert 93 of the driving member 90 is forced to contact or abut against the protrusion 84 of the support block 80, such as the second shoulder 86, the support block 80 is further forced to move downward such that the protrusion 81 and the protrusion 82 can be forced to move downward to separate from the weight plates 60,61 and the weight plates 62,63, such that the weight plates 60,61 and the weight plates 62,63 can be coupled or bonded to the housings 41,42,51,52 (FIG. 11) of the grips 4, 5. So that the driving member 90 is driven to rotate relative to the seat body 10 to actuate the protrusion 84 of the bearing block 80, thereby controlling the coupling relationship between the protrusion rod 81 and the protrusion 82 and the weight plates 60,61 and the weight plates 62, 63.
