Description

Adjustable sport body-building apparatus

Technical Field

The utility model relates to a sports fitness device, which is an adjustable sports fitness device, such as a dumbbell or a bar bell.

Background

There are many exercise and fitness apparatuses available in the market, such as a dumbbell, a kettle bell, a bar bell, and other load-bearing or weight-lifting apparatuses, which can be used to exercise the arms, and many exercise and fitness apparatuses, such as a dumbbell, a kettle bell, a bar bell, and the like, which can adjust different weights, thereby facilitating various people to exercise the muscles of the upper body of the user.

However, the weight adjusting mechanisms of the present weight-adjustable exercise device, dumbbell, kettle bell or bar bell are quite numerous and most of them are quite complicated, so that it is quite inconvenient to operate because a person needs a lot of procedures or actions or processes to adjust to different or required weights when operating or adjusting different weights.

In particular, the conventional weight-adjustable exercise device, dumbbell, kettle bell or bar bell includes a plurality of weight plates which are respectively inserted or mounted to two ends of a long shaft in sequence so as to be adjusted to different or required weights. However, these weight plates are inconvenient to handle and use, and are unfortunately not particularly capable of some fine weight adjustment.

In view of the disadvantages of the conventional exercise device with adjustable weight, the present invention has been developed through many researches and improvements to provide an exercise device with adjustable weight, which can be adjusted slightly.

SUMMERY OF THE UTILITY MODEL

It is an object of the present invention to provide an adjustable exercise device that can be fine-tuned for weight and that can be conveniently operated and used by, for example, women of relatively small stature.

Another object of the present invention is to provide an adjustable exercise device, wherein the structure is simplified, the device can be easily manufactured and assembled, and the device can be manufactured quickly, so that the manufacturing cost is relatively low.

The utility model relates to an adjustable exercise body-building device, which comprises a handle, a first end part and a second end part, and two shells which are respectively arranged on the first end part and the second end part of the handle; the method is characterized in that: a first weight block and a second weight block for engaging the housing, and a pawl on the handle that is actuated to selectively engage the weight block to removably mount the weight block to the handle.

The adjustable exercise device has a housing with a guide slot for sliding the pawl. The housing has a chamber communicating with the guide groove for accommodating the weight member.

In the adjustable exercise device, the first weight block has a groove for engaging the pawl. The first weight block has a cavity for accommodating the second weight block, and the first weight block has a side arm, and the caulking groove is formed in the side arm.

In the adjustable exercise device, the second weight block has a through slot for engaging the pawl. The second balancing weight has an outer arm, and the through groove is formed in the outer arm. The handle may further comprise at least one weight plate, and a bolt body slidably disposed in the handle, and the weight plate may be detachably mounted to the handle.

Detailed Description

Referring to fig. 1-5, the adjustable exercise device of the present invention mainly comprises a handle 10, and a plurality of weight blocks or weight plates 50, which are designed to be inserted into or mounted on the handle 10 in sequence, the number of weight blocks or weight plates being selected according to the user's requirement and mounted on the handle 10, wherein the handle 10 is generally in the shape of a long rod and has an inner hole 11, and has one or more than one, for example, two shells 20 are respectively disposed or formed on two

end portions

12, 13 of the handle 10 (fig. 2, 4-5), wherein the inner hole 11 of the handle 10 also passes through each shell 20, and each shell 20 has a dovetail groove 21 (fig. 1) communicating with the inner hole 11 of the handle 10.

The housing 20 has a cavity 22 above and also communicating with the inner bore 11 of the grip 10, and a shoulder 23 communicating with the cavity 22 of the housing 20. One or more plugs 14, 15 (fig. 1,5) are slidably disposed in the inner bore 11 of the grip 10 and can extend out of the shell 20 and the

distal portions

12, 13 of the grip 10, and the weight plate 50 can be detachably mounted to the

distal portions

12, 13 of the grip 10 or the shell 20. A base 80 is provided with a plurality of receiving slots 81 for receiving or accommodating the weight plates 50 and/or the housing 20. Each of the

pins

14, 15 has an upwardly projecting shaft and/or a resilient catch 17 for engaging a recess 22 or shoulder 23 of the housing 20 to locate each of the

pins

14, 15 to the housing 20 and/or the handle 10 and to prevent movement of the

pins

14, 15 and resilient catch 17 relative to the handle 10.

The housing 20 has a generally U-shaped chamber 24 for receiving or housing one or more accessory weights, and the accessory weights also have a generally U-shaped or U-shaped configuration for fitting within the chamber 24 of the housing 20. For example, as shown in fig. 1 and 6-8, the larger or first weight 51 has a cavity 53 for receiving or accommodating the smaller or second weight 52 and may form or constitute two side arms 54, each side arm 54 having a respective channel 55, the smaller or second weight 52 having a space 56 forming or constituting two outer arms 57, each outer arm 57 having a respective through-slot 58 aligned with the respective channel 55 of the larger or first weight 51. The housings 20 each have a channel 25 in communication with the chamber 24 for slidably receiving a pawl 30. the pawl 30 has a resilient catch or button 31 for guiding the pawl 30 to slide or slide relative to the housing 20 to selectively engage a side arm 54 of the first weight 51 or an outer arm 57 of the second weight 52.

In the operation of the present invention, please refer to fig. 8 again, when the pawl 30 is retracted into the guiding groove 25 of the housing 20 and does not extend into the accommodating chamber 24 of the housing 20, the pawl 30 will not engage the side arm 54 of the first weight block 51 or the outer arm 57 of the second weight block 52, so that the first weight block 51 and the second weight block 52 will not be connected or fixed to the housing 20. As shown in fig. 6, when the pawl 30 is moved in one direction, such as to the right, it engages the slot 58 of the outer arm 57 of the second weight 52, such that it selectively couples or secures the second weight 52 to the housing 20 and such that the second weight 52 can be moved away from the first weight 51. In addition, as shown in fig. 7, when the pawl 30 moves in another direction, such as to the left, it can engage with the engaging groove 55 of the side arm 54 of the first weight 51, so that it can simultaneously couple or fix the first weight 51 and the second weight 52 to the housing 20, and can be moved away from the seat 80, so as to selectively couple or fix the first weight 51 and/or the second weight 52 to the housing 20.

In the operation of the present invention, referring to fig. 4 and 5, the elastic buckle 17 drives the

bolts

14 and 15 to detachably mount a predetermined number of weight bearing pieces 50 on the

end portions

12 and 13 or the housing 20 of the handle 10, so as to adjust different weights. 6-8, the pawl 30 may optionally engage the through slot 58 of the outer arm 57 of the second weight 52 or alternatively engage the engagement slot 55 of the side arm 54 of the first weight 51 so that it may selectively couple or secure the first weight 51 and/or the second weight 52 to the housing 20 or removably mount to the

end portions

12, 13 of the handle 10 or the housing 20. It is to be noted therein that the first and

second weight members

51 and 52 are lighter in weight than the weight plate 50 so that they can be finely tuned for operation and use by users of different sizes.
