The present invention relates to a wrist exercise device, and more particularly, to a detachable case structure of a wrist exercise device.

Wrist exercise devices, including a hollow case interior in which a spherical rotor is rotatably supported, are known for the purpose of muscle movement and rehabilitation associated with the wrist. Several embodiments are disclosed in Taiwan Utility Model Publication No. 135058 and U.S. Patent Publication No. 5,800,311, both of which disclose rotary wrist mechanisms operated by simple rotation performed by wrist muscles.

Conventional wrist exercise apparatuses are exercise instruments that have a single function of exercising or strengthening muscles associated with the wrist. Although improvements have been known incorporating a light emitting device in a wrist exercise device to produce a luminous effect during operation of the wrist exercise device, the operation of a conventional wrist exercise device provides an audio effect for the enhanced sound / light entertainment effect. It can't be done. The addition of circuitry and additional electrical / mechanical elements to the wrist exercise device may cause sound and / or light emission during operation of the wrist exercise device, but there are losses due to the complex structure and increase manufacturing costs. In addition, the circuit must be powered by an internal or built-in power source, which has a very limited power capacity. Therefore, monitoring power loss is of particular interest to wrist exercisers. This is annoying.

Thus, there is a need for a wrist exercise device that overcomes the problems of the prior art device described above.

One object of the present invention is to provide an acoustic generating wrist exercise device comprising a rotor defining a range of an open chamber on both sides, forming a hole in an outer surface of the chamber, and communicating with the chamber. The centrifugal force generated by the rotation of the rotor causes the airflow between the hole and the chamber to produce the effect.

It is yet another object of the present invention to provide a wrist exercise device that generates sound without any electrical circuitry during operation and consumes no electric power.

In order to achieve the above object, according to the present invention, a case consisting of an upper case member and a lower case member paired with each other to form a hollow sphere, and a retaining ring fixed between the upper case member and the lower case member (retention ring), and a wrist exercise device including a rotor that is rotatably supported inside the case by the retaining ring. Cavities are formed on both sides of the rotor, each of which is divided into several chambers by partitions fixed within the cavity, and when the wrist mechanism is operated, the rotor is rotated and centrifugal force generated by the rotation of the rotor As a result, high speed airflow is generated between the hole and the chamber to generate sound without consuming a circuit board and electric power.

The present invention will become apparent to those skilled in the art upon reading the following description of the preferred embodiments with reference to the accompanying drawings.

1 to 5, a wrist exercise device constructed in accordance with a first embodiment of the present invention is generally denoted by the reference numeral 100 and is composed of an upper case member and a lower case member 10, 20. Wherein both the upper case member and the lower case member are hollow hemispheres that mate with each other along opposite mating edges delimiting an interior space therebetween (not shown). The upper case member 10 substantially defines the aperture 11 located on the opposite side of the lower case member 20. Each of the two apertures 12 and the two corresponding perforated lugs 21 are formed in the upper case member and the lower case member 10, 20 so as to be engaged and secured with respect to each other. The upper case member and the lower case member (10, 20) is fixed together.

The retaining ring 30 is inserted between the mating edges of the upper case member and the lower case member 10, 20. Holes 31 and 32 opposite to each other are delimited in retaining ring 30. The rotor 40 is housed in a sphere consisting of an upper case member and a lower case member 10, 20, and has axles 41, 42 positioned coaxially with each other and extending back to back. do. The mandrel 41, 42 is rotatably received in the holes 31, 32 of the retaining ring, and the holes 12 of the inner and upper case members 10 of the spherical case (or the holes of the lower case member 20). 21)). Thus, the rotor 40 can rotate about the mandrel 41, 42 and between the upper case member and the lower case member 10, 20.

The rotor 40 forms opposite cavities around the mandrel 41, 42. Partitions 43, 44 are disposed in the cavities, extend between the mandrel 41, 42, and are disposed inside the circumference of the cavity, each of which leads to a plurality of chambers 431, 441. Division (see FIGS. 3 and 4).

The circumferential groove 45 is formed along the circumference of the rotor 40 to accommodate the wire 451 wound around the groove. The electric wire 451 extends into the case by having an end portion passing through the hole 11 of the upper case member 10. By forcing the electric wire 451 through the hole 11 and forcing it outward, the electric wire 451 is released from the rotor 40, and by the friction between the rotor 40 and the electric wire 451, the rotor ( The driving force applied to 40 causes the initial rotation of the rotor 40. This is just one embodiment that causes the initial rotation of the rotor 40, and other means may be used to cause the initial rotation of the rotor 40 without departing from the scope of the present invention.

The holes 46, 47 are delimited at the outer surface of the rotor 40. The holes 46, 47 can be distributed on the outer surface of the rotor 40 in any desired pattern. In the illustrated embodiment, the holes 46 and 47 are each formed symmetrically in the case members 10, 20. While the hole 46 communicates with the chamber 431, the hole 47 communicates with the chamber 441 so that when the rotor 40 rotates between the upper case member and the lower case member 10, 20. Centrifugal force generated by the rotation of the rotor 40 causes high velocity airflow between the hole 46 and the chamber 431 and between the hole 47 and the chamber 441, which is a sound that generates a sound such as a whistle sound. It will act as a generator.

6 and 7 showing the rotor constructed in accordance with the second embodiment of the present invention, each of the partitions 43 and 44 has a notch 432 at the bottom edge corresponding to the holes 46 and 47. , 442, and the high velocity airflow generated between the hole 46 and the chamber 431 by the rotation of the rotor 40 (and between the hole 47 and the chamber 441) is notched 432, 442 ), The tone and sound level can be changed by the airflow. Notches 432 and 442 may be of any desired shape, and in the illustrated embodiment are arc notches.

8, 9, and 10 each show a third embodiment, a fourth embodiment, and a fifth embodiment of the rotor 40. In the third embodiment shown in Fig. 8, the notches indicated by 432a and 442a are square. In the fourth embodiment shown in Fig. 9, the notches indicated by reference numeral 432b and reference numeral 442b are saw-tooth-shape. In the fifth embodiment shown in Fig. 10, the notches indicated by 432c and 442c are triangles. The shape of the notches 432, 442 (432a, 442a; 432b, 442b; 432c, 442c) allows the rotor 40 to produce different timbres and different sound levels.

According to the present invention, when the wrist movement mechanism is operated, the rotor is rotated and high speed airflow is generated between the hole and the chamber due to the centrifugal force generated by the rotation of the rotor, thereby generating sound without consuming the circuit board and the electric power. .

Although the invention has been described with reference to the preferred embodiments, it will be apparent to those skilled in the art that various modifications and changes can be made without departing from the scope of the invention as defined in the claims.
