Description of the Related Art Conventionally, methods often used for adjusting the height of washing machines, office chairs, and the like include loosening a nut, turning a bolt to adjust the height, tightening the nut, and pulling a lever. If the seating surface rises naturally and a vertical mechanism by a gas spring that can be fixed to a desired height can be raised, the former has a disadvantage that the height adjustment work is troublesome, and the latter has a high cost. For this reason, Japanese Patent Laid-Open No. 2-7 describes an adjusting leg capable of adjusting the height by an inexpensive and simple operation.
There is an invention described in 4298 Go. As shown in FIGS. 9, 10 (at the time of disengagement) and FIG. 11 (at the time of fixing), this is provided with a leg bearing 2 provided at a lower portion of the device 1, and provided on the leg bearing 2 so as to be vertically movable. A leg 4 constantly urged downward by a leg spring 3, and an adjusting knob 5 rotatably mounted on the leg bearing 2, and a plurality of split grooves 6 extending up and down around the circumference of the leg bearing 2. And a plurality of first ribs 8 extending up and down are provided on the outer diameter portion of the partition wall 7 of the leg bearing 2, and the inside of the adjustment knob 5 is multiplied. A plurality of second ribs 9 which are formed in a rectangular shape and extend vertically in the inner surface thereof are provided, and the outer diameter portion of the partition wall 7 of the leg bearing 2 is surrounded by the inner diameter portion of the adjustment knob 5, so that the rotation of the adjustment knob 5 The partition wall 7 moves to change the inner diameter 10 of the leg bearing, and the adjustment knob 5 The rotation angle is restricted by the abutment between the first and second ribs. When the rotation angle of the adjustment knob 5 is restricted, the leg bearing inner diameter 10 becomes small, and the vertical direction of the leg 4 is reduced. Is configured to prevent the movement of However, in these conventional adjusting legs, the inner diameter of the bearing changes by turning the adjusting knob, and the leg can be fixed (see FIG. 11) or disengaged (see FIG. 10). However, in order to make the leg bearing inner diameter 10 smaller, the adjustment knob 5 inner diameter portion 1
Since the partition wall 7 of the leg bearing 2 is forcibly elastically deformed in 1, there is a possibility that it may be broken during repeated elastic deformation, or it may be difficult to restore elasticity because a long-term stress is applied at the time of fixing. Was. In addition, since the inner diameter portion 11 of the adjustment knob 5 and the dividing wall 7 of the leg bearing 2 are rubbed with a force applied thereto, there is a fear of wear during repeated adjustment work. If too much force is applied when turning the adjustment knob 5, the adjustment knob 5 may be elastically deformed and broken such that the first rib 8 gets over the second rib 9. Therefore, the present applicant has filed Japanese Patent Application No. 8-67399 in order to solve the above problems. The protective leg of the device disclosed therein is disposed in the lower mounting hole 13 of the outer frame of the device 12 as shown in FIG.
And a mounting case 14, 15 for penetrating the shaft portion 20 of the leg 18 along the axial center, and the case 14, 15. A lock 16 includes a lever 16 housed and rotatably provided left and right, and a lock piece 17 which is guided by a cam groove 22 provided in the lever 16 by rotating the lever 16 to reduce or enlarge the diameter. The concave / convex portion 21 is locked or released by reducing or expanding the diameter of the piece 17, and the lock piece 17 expands or contracts in accordance with the cam groove 22 just by turning the lever 16 right and left. Since the lock piece 17 can be released or fixed, no force such as deformation is applied to the lock piece 17. Therefore, it is possible to provide a device adjusting leg which is hardly damaged or worn even when the adjusting operation is repeatedly performed.
