It is equipped with The vertical clutch 16 is rotatable relative to the worm shaft 15, and
It is interlocked and connected to the nut member 14 via the belt 21. Further, the fir clutch 18 can rotate integrally with the worm shaft 15 and is operatively connected to the fir drive shaft 23 via the worm gear groove 22. The clutch pulley 18 is connected to the output pulley 25 of the motor 10 via the belt 24.
is linked to. Therefore, the solenoid 22
If both clutches 16 and 17 are actuated alternatively, the frame 19 is rotated by forward or reverse rotation of the motor 10.
It is possible to drive the fir ball 11 up and down and to rotate the fir ball 11.

An upper limit sensor 26 and a circle sensor 27 are provided at both upper and lower ends of the guide frame 8 to detect the upper and lower limit positions of the frame body 9.

As shown in FIG. 3, the left and right fir balls 11 are rotatably fitted onto inclined shaft portions 29 inclined in opposite directions on an eccentric shaft 28 in the left and right direction. The eccentric shaft 28 is the fir drive shaft 23
Both ends are connected to a supporting shaft 30 which is rotatably supported by the frame 9 on the same axis in opposition to the supporting shaft 30 . Therefore, when the fir drive shaft 23 rotates, the left and right fir balls 11 move in an eccentric arc ellipse while moving forward and backward in accordance with the eccentricity of the eccentric shaft 28. The intervals are starting to change. That is, the distance between the tip pine serge portions that protrude maximum from the backrest portion 1 is expanded or contracted. A disk 31 is provided at the outer end of the support shaft 30, and a fir ball position sensor 32 is attached to the frame 9 in correspondence with the disk 31. This position sensor 32 is connected to the fir ball 11
It is configured to detect through the disc 31 that the vehicle has retreated backward.

This pine surge machine has pine surge functions such as straightening the spine, raising and lowering the fir by the operation of the fir ball 11, and its control device is constructed as shown in FIG. This control device consists of an electronic control circuit 3 with a built-in microcomputer.
3, various sensors 26, 27, 32, various operation keys 34, storage key 35, motor 9, solenoid 2
0 etc. are connected. The electronic control circuit 33 includes a main processing means 36 that automatically or manually processes various pine surge functions according to commands from the operation keys 34, and a fir check means 37 that checks the operation of the fir ball 11 according to each pine surge function.
After the pine surge operation is completed, the fir balls 11 are moved to the lower limit position, and the pair of fir balls 11,
11, and storage control means 38 for storage in the maximum (expanded) position. Here, the maximum mutual distance position refers to the case where the mutual distance between the tip pine serge parts that protrude to the maximum from the backrest part 1 is the maximum, and each fir ball 11, 11 is facing forward in a plan view. It is being expanded gradually. The storage control means 38 is configured to automatically store the fir balls 11 after the automatic mode ends during automatic operation, and to store the fir balls 11 by key input from the storage key 35 during manual movement using the operation key 34. It's summery. Therefore, in this pine surge machine, after the pine surge operation is finished, the fir balls 11 are always lowered to the lower end position of the backrest part 1 and are stored in a position retreated to the rear side of the backrest part 1, and the left and right fir balls 11, 11 It stops at the expanded position.

Next, the operation will be explained with reference to the flowcharts shown in FIGS. 5 to 7. The pine surge machine usually performs the pine surge operation by using a pair of left and right fir balls 11 to straighten the back straighten, or to raise and lower the fir. but,
After finishing the pine surge operation, the fir balls 11 become a hindrance when used as a chair, so the fir balls 11 are lowered to the lower limit position, reversed back and forth, and stored in a retreated state to the rear side in the backrest part 1. Control at this time is performed by the storage control means 38 according to the fir ball storage program.

That is, in the case of the automatic course, control is performed according to the stop program of the main processing means 36.
In the step shown in FIG. 5, it is determined whether the automatic course timer is starting, and if YES, the process returns to the main processing program of the step and continues the pine surge operation. If NO, the pine surge operation has ended, so the automatic pine surge end buzzer is activated (step), and the vertical movement stop processing command (step) and the fir movement stop processing command (step) are sequentially issued. , issues a fir operation position check command (step). At this time, a command and check as to whether the fir ball 11 is reliably stored is given to the fir ball check program shown in FIG. 7 (step). If it is stored, the confirmation command is returned to the step, and the process moves to the termination processing command (step). Next, a timer count command (step) for the end buzzer, a end buzzer command (step), and a program end command (step) are issued in sequence, and the process returns to the main process (step).

When the storage key 35 is operated, the key input buzzer command (step), as shown in FIG.
After passing the vertical movement stop processing command (step), motor stop processing command (step), fir movement processing command (step), and fir movement stop processing command (step), it is determined in step whether the storage operation is in progress. If YES, a fir ball position check command is issued to the fir check program shown in FIG. 7 (step). At this time, if the fir ball 11 is in the predetermined position, the confirmation command is returned to the step, a storage completion command is issued (step), and when the storage is completed, a cancel command is issued to all timers, and then the process returns to the main process ( step).

During the momi check, the program shown in FIG. 7 is followed. That is, in the stop program of the automatic course (main process) or the storage program by inputting the storage key, if the program progresses to the fir check, the fir ball 11 is stored and confirmed in the fir check program. First, in step, it is determined whether the fir ball 11 is in the fixed position stopping operation. At this time, stopping at a fixed position refers to a state in which the fir balls 11 are protruded to the front side. Since the massaging operation ends when the fir ball 11 is stopped at the fixed position, if the operation is stopped at the fixed position, it is determined in step whether the storing operation is in progress. If the half-cut at the step is YES, the fir ball moves in the forward direction (step), and if it is NO, the fir ball moves in the reverse direction (step). In step 〓〓, it is determined whether the detection by the position sensor 32 at the fir ball storing position is OK. At this time,
If YES, then it is determined whether timing monitoring of the position sensor catch is OK, that is, whether time-up monitoring is OK (step 〓〓). Step〓〓
If the determination is NO, the program proceeds in the A direction. This is a case where the fir ball storage position cannot be detected by the position sensor 32. Step〓〓
If YES, issue a command to rotate the fir ball at step 〓〓. Also, if NO in step 〓〓, the program progresses in the forward rotation direction of the fir ball and issues a rotation command for the fir ball 11 (step 〓〓), and if YES, it returns to step 〓〓 and starts the step again in the confirmation program. → Step 〓 〓 → Step 〓〓. If NO at step 〓〓, or NO at step, etc., return to the step. When the fir ball 11 rotates forward according to the command at step 〓
Issue an OFF command (Step 〓〓), stop the fir ball 11 at the storage position, and issue a timer set and stop command for the fir ball brake (Step 〓〓).
Then, the process passes through step 〓〓, issues an ON command to the fir ball brake (step), and completely stops the fir ball 11 at the storage position using the fir ball brake. If you can store fir ball 11,
After a certain period of time, turn on the fir ball brake.
Issue a command to turn it off (step). This completes the entire operation of storing the fir balls 11, so the process returns to the initial program (main processing program) (step). It also issues an OFF command for the motor 10 and solenoid 20 (Step 〓〓), returns to the main processing program, and at the same time issues a momi check OK command to the main processing program (Step 〓〓). Returning to the main process,
Issues a fir ball position check OK command to the step in the automatic course stop program.

When the program progresses from step A in the direction, that is, the position sensor 32 cannot detect the storage position of the fir ball 11, and the judgment at step 〓〓 is incorrect.
If NO, proceed to step 〓〓. The same applies when the step decision is NO. In step 〓〓, it is determined whether or not the timer of the fir ball brake is counting. If YES, go through the steps 〓〓〓〓〓〓, and if NO, turn on the fir ball brake (step).

〔Effect of the invention〕

According to the present invention, after the pine surge operation is completed,
Since the fir ball storage control means 38 is provided to store the fir balls 11 at the lower end position and the maximum mutual spacing (expanded) position, the fir balls 11 are always lowered, expanded, and stopped after the pine surge operation is completed. Therefore, even when used as a simple chair, the fir ball 11 does not get in the way. The fir balls 11, 11 do not get in the way. In particular, even when the user sits deeply, the fir balls 11, 11 gradually expand forward, so that the buttocks are
It will not get in the way by intervening between 11 and 11.

In addition, the pine surge operation is performed by fir balls 11,1
1 performs an eccentric circular arc elliptical movement moving forward and backward in the front-back direction, and the mutual distance between the tip pine serge parts expands and contracts, so the position of pressure of the tip pine serge part on the pine surge target part changes slightly, resulting in an extremely excellent pine surge effect. It will be shown.
