JP2554773Y2 - Kneading position control device for seat-chair type massaging machine - Google Patents

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to the improvement of a seat-type masseter, and particularly to a masseter with a structure in which both sides of a spine are kneaded. The present invention relates to a position control device.

[Conventional technology]

Conventionally, a sliding frame provided with a plurality of small planetary rollers is screwed onto a threaded rod rotated by a motor, and the sliding frame is moved by driving the motor. An abrasion machine having a structure that is driven to rotate while floating up and down along the curve of the sword is used.

[Problems to be solved by the invention]

In other words, this kind of chair for massage is for kneading up and down along the spine, but has a problem that the kneading position cannot be freely changed at the request of the user. In addition, since the massaging machine is a chair type, it is often used as a chair even when not in use, but in this case, if the roller for kneading is at the lumbar position, it will not only be an obstacle, There was a problem that it was unpleasant and unpleasant.

The present invention has been made in view of the above problems, and a massage position can be freely selected and changed, and a massage position control device in a chair-type masseter that waits at a position where a massage member does not interfere with a user when not in use. The purpose is to provide.

[Means for solving the problem]

In order to achieve the above object, a kneading position control device in a seat-chair type massaging machine according to the present invention includes a sliding frame receiving hole formed by opening a threaded rod rotated by a motor at the center of a backrest frame. At the center of the
A rack gear and a guide rail are configured so as to be parallel to both sides of the threaded rod, and have side surfaces having undulations. The sliding frame screwed with the threaded rod is arranged along the guide rail. A rotating shaft that slides and rotates by meshing the rack gear and the gear is pivotally mounted, and a pair of star frames having a number of small rollers around the shaft are axially mounted on both ends of the rotating shaft. A plurality of non-contact type position sensors are arranged at one side of the sliding frame receiving hole formed in the center of the backrest frame in a direction not to interfere with the sliding frame in the direction of the threaded rod. A sensor driver for turning on the position sensor is fixed to a part of the moving frame, and the detection output from the position sensor allows the motor to be turned on or off by a selection input from an operation switch configured on the side wall of the backrest. "OFF", "Forward" And a controller for controlling the “reverse rotation”, and further drives the sliding frame up and down within the range of the kneading position designation set by the input signal from the operation switch, and the sliding frame is moved up or down in any direction. The sliding frame is stopped at a standby position by a stop input signal of the operation switch even during driving.

[Action]

According to the above configuration, the motor is controlled to “forward”, “reverse”, and “stop” by the input of the “ON” from the operation switch and the “kneading position designation” signal via the controller, The position of the sliding frame is constantly detected from each of the position sensors. Therefore, while driving according to the range of "designation of massage position" input from the operation switch,
When the “OFF” signal is input, the motor is rotated so as to move upward regardless of whether the sliding frame is sliding up or down, and the kneading member provided at the upper end is used by the user. "Stops" by position detection by a position sensor at a position where it does not interfere with the position.
