Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a massaging machine that swings massaging balls.

[Prior art] A massaging machine that swings the massaging balls applies large external forces in all directions to the massaging balls, so the arms that support the massaging balls are
Must be of strong construction.

For this reason, conventionally, as shown in FIG. 3, the arm 2 attached to the swing frame 1 could not be constructed from a single member.
Welding was required to get it into the desired shape. [Problems to be solved by the invention] In the conventional structure, welding is sometimes disliked due to the plating of the arm, making it troublesome to manufacture, and also causing damage such as cracks if the material changes due to welding. Easy to generate, easy to manufacture, and durable!
A T4 model was desired.

The present invention was made in view of these circumstances, and
Even plated arms can be easily manufactured, and
按II with a durable structure! Our goal is to provide opportunities.

[Means for Solving the Problems] The present invention has one end of a rod-shaped arm support a massaging ball, the other end of this arm bent into a dogleg shape, and a swinging frame provided with a hole with which the arm is attached. The problem can be solved by inserting the other end into the swinging frame, forming a lever for gripping the dogleg-shaped part of the arm, and fitting it together to integrate the massaging balls and the swinging frame. has been resolved.

[Function] When the swinging frame is rocked, massage can be performed with the kneading balls through the arms, and the arms transmit the load.

The arms are bent into a dogleg shape and are held at different angles by the holes and grooves of the swinging frame, so that even if external forces are applied to the kneading balls in any direction, the swinging frame and the durable integral structure are maintained. Become.

[Example] The present invention will be explained based on an example not shown in the drawings. Fig. 1 is a vertical cross-sectional view of a main part of a massaging machine according to an example of the invention, and Fig. FIG. 3 is an enlarged perspective view of main parts.

In FIG. 1, the massaging machine has an arm 4 mounted on a swinging frame 3.
A massaging ball 5 is provided at one end of the arm 4.

The other end of the arm 4 is formed with a grip portion 6 bent in a dogleg shape.

Furthermore, the other end of the grip part 6 bent in a dogleg shape is inserted into a hole 7 formed in the swing frame 3, and the bent part in the dogleg shape is formed in the swing frame 3. erased 8
is mated to.

The swing frame 3 is fixed to a shaft 9, and is connected to a drive source 10.
It is configured to be swung by.

In FIG. 2, the swing frame 3 is made of a molded member such as plastic, and grips a grip portion 6 of an arm 4 bent in a dogleg shape through a groove 8 and a hole 7.

) The arm 4 is configured to be fixed with a screw 11 so that it cannot be pulled out from the hole 7.

The fixation using the screws 11 is not limited to this method, and the arm 4 may be fixed by passing through the swing frame 3 and tightening the end portion with a nut.

In such a configuration, when the drive source 10 is driven, the massaging machine can swing the swinging frame 3 to swing the massaging balls 5 via the arm 4, thereby performing massaging.

When a load is applied to the massaging balls 5, that is, when an external force is applied to the massaging balls 5, the arm 4 transmits the load between the swinging frames 3 and 3. This load transmission is performed in various directions. It becomes the power of

However, arm 4 is fl! 2@ is held in the hole 7 and spring 8 of the swinging frame 3, and the arm 4 is bent into a dogleg shape so that it is integrated with the swinging frame 3 in all directions.

Therefore, the massaging balls 5 are moved to the swinging frame 3 by the arm 4.
It becomes one with the body and does not come off easily.

Further, it does not need to be fixed by welding, and even if it is fixed to the swing frame 3 by welding, the part near the massaging balls 5 will not be welded, and the arm 4 will be plated before being erected. Furthermore, damage due to metal fatigue due to changes in the material due to welding will not occur.

Of course, it is also possible to press-fit the arm 4 into the hole 7 of the swing frame 3 and fix it there; since it is bent in a dogleg shape, there is no problem with press-fitting, and assembly is easy.

Such an arm 4 is easy to manufacture because it forms a side path that is bent into a dogleg shape to be gripped, and an arm 4 having a large outer diameter can be easily used.

[Effects of the Invention] According to the present invention, since the arm is bent into a dogleg shape and the swinging frame is gripped by forming holes and grooves, the structure is simple and easy to manufacture, and the massager has a durable structure. This opportunity can be obtained, and its effects are extremely large.

Claims (1)

[Claims] In a massaging machine that oscillates massaging balls, one end of a rod-shaped arm supports the massaging balls, the other end of this arm is bent into a dogleg shape, and the other end of the arm is inserted into a swinging frame provided with a hole. A massaging machine characterized in that the swinging frame is formed with a groove for gripping the dogleg-shaped portion of the arm, and the grooves are fitted into the swinging frame to integrate the massaging balls and the swinging frame.
