Patent Application
20240359046
The present disclosure relates to the technical field of fitness equipment, more particularly to a training apparatus capable of being quickly combined into a dumbbell and a kettlebell.
Modern urbanites are experiencing high working intensity, so exercising and running have gradually become popular. However, due to time constraint, it is impossible for them to go to the gym usually. Therefore, small sized exercising apparatuses are needed that can be used at home, among which dumbbells and kettlebells are the most common. If the two can be combined into one, not only can the cost for purchasing apparatuses be saved, but convenience can also be brought to storage and usage.
In order to address the above technical problems, existing training apparatuses often realize a transformation thereof employing threaded connection or lock-pin connection, thereby to achieve a combination of two in one. However, the above connection method is cumbersome, and it is needed to perform adjustment during the connection process, making the difficulty and time of transformation of the apparatus increased.
It is an object of the present disclosure to provide a training apparatus capable of being quickly combined into a dumbbell and a kettlebell to address the above problems, which improves the issues that the training apparatus has difficulty in transformation and the transformation needs a long time.
The present disclosure achieves the above object employing the following technical solutions. A training apparatus capable of being quickly combined into a dumbbell and a kettlebell includes:
Preferably, an opening of the snap ring has a protrusion forming a limit part, and an outer wall of the snap-fit block forms a protruded block used in fitting with the limit part. During the usage of the training apparatus, the snap ring and the snap-fit block can form an integral closed ring, enhancing the steadiness of snap-fit connection therebetween.
Preferably, a side surface of the weight block is formed with two hollow holes, the mounting groove is intercommunicated with the hollow hole, and the abutting block has one end extending through the mounting groove into the hollow hole. It is more convenient to disassemble the training apparatus and the steadiness of the training apparatus during usage is not affected.
Preferably, a side surface of the kettlebell body is formed with two receiving cavities, and the receiving cavity is matched with the handle in shape. When the training apparatus is used as a kettlebell form, the handle is received into the kettlebell body, reducing the risk of being lost.
Preferably, the end part of the kettlebell body, the end part of the handle and the other side of the weight block are each fixedly connected with a mounting block, and the mounting block is fixedly connected to the snap-fit block. It is convenient to replace the corresponding snap-fit block during later periods, thereby facilitating the easy maintenance of the training apparatus.
The present disclosure has the following beneficial effects.
In the above connecting mechanism, the snap-fit block and the snap ring are mutually matched in shape, which can quickly achieve a closed connection state. After rotation to place, the abutting blocks will autonomously extend out of the mounting grooves to lock the snap-fit block with a diagonal distribution. The above connection method is simple in operation and low in mounting difficulty, whereby the training apparatus is convenient to transform and achieves an effective combination of two in one. Furthermore, the handle can be received into the kettlebell body, reducing the risk of being lost.
Reference numerals in the drawings are illustrated as below. 100, weight block; 110, mounting groove; 200, kettlebell body; 300, handle; 400, connecting mechanism; 410, snap ring; 420, snap-fit block; 430, abutting block; and 431, torsion spring.
The technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings of the embodiments of the present disclosure. Apparently, the described embodiments are merely certain embodiments of the present disclosure, rather than all of the embodiments. All of the other embodiments that a person skilled in the art obtains on the basis of the embodiments of the present disclosure without paying creative work are intended to fall within the protection scope of the present disclosure.
During specific implementation, as shown in
As shown in
In the present embodiment, after the snap-fit block 420 is rotated 90 degrees, the snap ring 410 and the snap-fit block 420 can form an integral closed ring, enhancing the steadiness of snap-fit connection therebetween.
As shown in
In the present embodiment, during a disassembly operation, a hand extends into the hollow hole of the weight block 100 and presses against the two abutting blocks 430 simultaneously from lateral sides, after which the other ends of the abutting blocks 430 are received into the mounting grooves 110, whereby it is more convenient to disassemble the training apparatus and the steadiness of the training apparatus during usage is not affected.
As shown in
In the present embodiment, when the training apparatus is used as a kettlebell form, the handle 300 is received into the receiving cavity before completing the installation of the other side of the kettlebell body 200. The design of receiving the handle 300 into the kettlebell form reduces the risk of the handle 300 being lost.
As shown in
In the present embodiment, it is more convenient to mount the snap-fit block 420 and it is also convenient to replace the corresponding snap-fit block 420 during later periods, thereby facilitating the easy maintenance of the training apparatus.
The working principle is as follows. When it is needed to transform the training apparatus into a kettlebell, enter the snap-fit block 420 into a mounting area from a notch of the snap ring 410; by the time, the snap-fit block 420 squeezes against the abutting blocks 430, and the abutting blocks 430 are squeezed into the mounting grooves 110. Then, the snap-fit block 420 is rotated 90 degrees, so that the limit part and the protruded block form into a closed state. Thereafter, the abutting blocks 430 lose the squeezing from the snap-fit block 420 and extend through the mounting grooves 110 under the function of the torsion springs 431 to limit two diagonal positions of the snap-fit block 420, thereby achieving a stable connection after transformation. Next, the handle 300 can be received into the receiving cavity. Similarly, corresponding weight blocks 100 can be mounted in sequence with the above principle. When it is needed to transform the training apparatus into a dumbbell, the operation is similar to the above principle. During the disassembly of the apparatus, a hand extends into the hollow hole of the weight block 100 and presses against the two abutting blocks 430 simultaneously from lateral sides, after which the other ends of the abutting blocks 430 are received into the mounting grooves 110 and in the meantime the abutting blocks 430 do not lock the snap-fit block 420. Then, rotate the snap-fit block 90 degrees to complete the disassembly of the training apparatus.
In addition, it should be understood that although the present specification has been described according to embodiments, it does not mean that each embodiment includes only one independent technical solution. Such narration method of the specification is merely for clear illustration. Those skilled in the art should view the specification as an entirety. Technical solutions in each embodiment can be properly combined to form some other embodiments that those skilled in the art can understand.
