Description

[Detailed description of the invention] The present invention describes the structure of the mounting part of the vibration device in a pine surge machine, specifically, the mounting part of the vibration device when used together with the pine surge machine equipped with a rubbing and massaging pine surge device. It is related to the structure of

In recent years, a wide variety of pine serge machines have been provided in response to the needs of users, and in particular, those with multiple functions such as reciprocating rubbing and kneading rollers are equipped with a vibration device, and both pine surges move back and forth. There is an increasing demand for pine surge machines.

However, when the rubbing roller and the vibration device are attached to a support arm that reciprocates and the vibration device is operated, vibrations are transmitted to the guide roller via the support arm, and the contact area between the guide roller and the guide rail is affected by the vibration. This generates a lot of noise, which not only causes discomfort to the user, but also accelerates the wear and tear of various parts, and there has been a strong demand in the industry for effective measures to suppress this vibration noise.

The present invention provides a structure for mounting a vibration device that is extremely effective in preventing the generation of vibration noise when using the above-mentioned vibration device, and the main parts are shown in FIGS. 1 and 2. As shown in the figure, it is equipped with rotatable ring members 1, 1 at appropriate intervals on both sides of the outer periphery to prevent friction with the cloth a and to massage the sides of the spine, and has an eccentric weight inside that serves as a vibration source. On the left and right end surfaces of the drum-shaped vibrating device main body 3 equipped with the motor 2,
At least two loops 4 formed of string-like elastic material
.
Inside the loops 4, 4 protruding from 6, the loops 4,
4 is in a tensioned state, a pin shaft 7 is inserted through the pin shaft 7, and the pin shaft 7 is mounted between the left and right support arms 5.5.

Embodiments of the present invention will be explained below in detail based on drawings showing embodiments of the present invention. Figs. 2 and 3 show the device section of a pine surge machine in which a device equipped with a rubbing roller and a vibration device moves back and forth in the vertical direction. It shows a schematic plan view and a schematic side view of 1, as is well known.
A rubbing roller 8 consisting of a pair of rollers is pivotally supported by an arm 11 attached to a nut body 10 which is moved back and forth by the rotation of a screw shaft 9, and a guide roller 12 is moved along a guide rail 13. It has become.

Reference numeral 14 denotes a spring that elastically biases the arm 11 toward the guide rail 13 side.

A support arm 5 for mounting the vibrating tool main body 3 is pivotally connected to the shaft 31 of the above-mentioned rubbing roller 8, and a bracket 15 extending toward the guide rail 13 is provided on the free end side of the support arm 5. is attached, and the bracket 1
At the end of the guide rail 13, a first
A guide roller 16 and a second guide roller 18 that abuts a lifting guide 17 attached to a portion of the guide rail 13, for example, a portion of the rail 13 where the waist, shoulders, etc. of the human body are located, are provided. When reaches the lifting guide 17, the second guide roller 18 rolls on the lifting guide 17, and when the part of the support arm 5 comes off the lifting guide 17, the first guide roller 16 rolls on the guide rail 13. It is designed to roll.

Reference numeral 19 denotes a spring that elastically urges the support arm 5 toward the guide rail 13 side.

Next, as described above, the main body 3 of the vibrating device is mounted on the support arm 5 by means of the loops 4, 4 of elastic material and the pin shaft 7, and its components are shown in FIGS. 4 to 13. The ring member 1.1 is rotatably fitted on both sides of the cylindrical body made of synthetic resin, the adhesive ring 21 for locking the fitted ring members 1, 1, and the cylindrical body 20 is equipped with a glue ring 21. A small motor 2 for generating vibrations having an eccentric weight 23 fixed to a rotating shaft 22, the small motor 2 being elastically held and fitted into a cylindrical body 20;
Rubber elastic caps 24 and 25 forming both end surfaces of
, and a weight balance 26 fitted within the elastic cap 24.

The loop member has an elongated oval shape as shown in FIG. 12, and has a straight portion 27. between the loops 4 at both ends.
27 is formed with a flange-like seat 28.28 at a position corresponding to the width dimension of the cylindrical body 20, and a straight portion 2 of the loop member is formed in a groove 29.29 provided on the inner surface of the cylindrical body 20.
7 and positioning the flanged seats 28 and 28 on the left and right end surfaces of the cylindrical body 20.
The elastic caps 24 and 25 fitted into the cylindrical body 20 are prevented from being pulled out, and the loops 4, 4 are made to protrude from both end surfaces of the cylindrical body 20.

However, the means for protruding the elastic loops 4, 4 from both end faces of the cylindrical body 20 is not particularly limited.

On the other hand, the pair of loops 4, 4 protruding from the end face of the vibrating device main body 3 can be inserted into the left and right support arms 5, 5 for mounting the vibrating device main body 3, as described above. Elongated holes 6, 6 are bored, and the main body 3 of the vibrator is positioned between the left and right support arms 5.
4 into the elongated hole 6.6, and while pulling the loop ends slightly protruding from the elongated holes 6, 6, insert the bulges 30, 3 at both ends.
0 is inserted into the loops 4, 4, and the main body 3 of the vibrator is thus mounted on the support arm 5.

Thus, the present invention has a ring member 1 that is rotatable on both sides of the outer circumference.
. , 4 at intervals, and the loops 4,
4 is inserted into the long holes 6, 6 provided in the support arm 5, and the pin shaft 7 is inserted inside the loops 4, 4 protruding from the long holes 6, 6, with the loops 4, 4 in tension. Since the main body 3 of the vibrator is inserted between the left and right support arms 5, 5, the main body 3 of the vibrator is reciprocated together with the rubbing roller (or massaging roller) 8, as in the past. Not only can two types of massage, rubbing and vibration, be applied to the back of the human body, but the vibrating device main body 3 is attached to its support arm 5.5 via elastic loops 4, 4. The vibration caused by the operation is absorbed by the elastic loops 4, 4, and the transmission of the vibration to the support arms 5, 5 is alleviated, and there is almost no generation of the annoying metal vibration contact noise that is conventional. , can carry out pine surge quietly and comfortably.
