JP2008168101A - Vertically movable saddle for light work - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that an aid which can be easily carried and used immediately on the spot is demanded since there is a lot of work in a half-sitting position for the light work of machine assembly, trial run adjustment, and wiring and piping, work time at the height is long, pains and fatigue are generated by the burdens of body weight put on the feet, the knees and the lower back, and a work place is often changed. <P>SOLUTION: In order to carry and operate the vertically movable saddle for light work anywhere, a battery power source 10 is used, a ball screw 3 is driven by a geared motor 4 with a brake and the saddle 14 is elevated and lowered corresponding to the work height. In order to easily execute the height adjustment of the saddle 14, operation push buttons 13a and 13b are arranged at such a position that they are not erroneously operated while sitting on the saddle. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The present invention relates to an elevating saddle for light work that receives a load of weight on a foot, a knee and a waist by a saddle during mechanical assembly, trial run adjustment, and light work at the middle waist of wiring piping.

Machine assembly, trial operation adjustment, and light work of wiring piping are quite middle and low back work. Also, since the working time at that height is quite good, pain and fatigue occur due to the burden of weight on the feet, knees and hips.

Machine assembly, trial operation adjustment, and light work of wiring piping are quite middle and low back work. Also, since the working time at that height is quite good, pain and fatigue occur due to the burden of weight on the feet, knees and hips. Because the work place changes frequently, it is necessary to make it easy to move.

A saddle 14 is attached as a seat so that work can be easily performed at any height, and the ball screw 3 is driven by a geared motor 4 with a battery power supply brake so that the height of the saddle can be easily adjusted on the spot.
In order to make it easy to adjust the height while sitting on the saddle, the operation buttons are separately arranged on the saddle mounting part for raising and lowering to prevent incorrect operation.
The structure is small and lightweight so that it can be easily carried.

A saddle 14 is attached to enable sitting at any height of the middle waist, and the position of the saddle can be adjusted by operating the operation buttons while sitting. The ball screw 3 is used to reduce the motor capacity, and the geared motor 4 with brake is driven, so that any position can be held according to the working posture. It is convenient to carry because it is a battery power source so that it can be used in any work place, and the lifting guide is a combination of the outer cylinder 1 and the inner cylinder 2 and has a small and lightweight structure.
Hereinafter, embodiments of the present invention will be described.
(I). A saddle 14 that can be used as a seat at any height is attached to the outer cylinder, and can be raised and lowered to an arbitrary height by the electric motor driven ball screw 3.

FIG. 1 shows a front view, a side view, and a plan view of a state in which an operator sits on an elevating saddle for light work.
The front view shows a sectional view of the ball screw attached. FIG. 2 is a detailed cross-sectional view of the parts A, B and C shown in the front view of FIG.

In FIG. 1, the components of the lifting saddle are shown. A saddle 14 is attached to a saddle support 15 attached to the outer cylinder 1. A support unit 6 fixed to the ball screw 3, a coupling 7, and a geared motor 4 with a brake are attached to the upper portion of the outer cylinder 1.
A ball screw nut 5 is attached to the upper part of the inner cylinder 2, and the outer cylinder 1 is raised and lowered and the saddle 14 is raised and lowered by three rotations of the ball screw. A guide bush 16 for guiding the inner cylinder 2 and upper and lower limit detection sensors 11a and 11b are attached to the lower part of the outer cylinder 1. An operation button for driving the geared motor 4 with brake, an ascending push button 13a, and a descending push button 13b are attached to the saddle support 15 attached to the saddle 14 so as to be operated with the left hand and the right hand. For safety, it is installed separately on the right side and left side so that you can not operate both with one hand. For grounding, a pad 19 for preventing slipping is attached to four struts 18.

In FIG. 2, the details of the A part are the mounting state of the support unit 6 that transmits the load from the saddle 14 to the ball screw 3 at the upper part of the outer cylinder 1, the coupling 7 that transmits the rotational force of the geared motor 4 with brake to the ball screw, and the battery. The arrangement of the battery box 10 for storing the battery is shown.

In FIG. 2, B part details show a state where a load applied to the ball screw 3 is received by the ball screw nut 5 and transmitted to the inner cylinder 2. The moment load applied to the outer cylinder 1 is also received.

In FIG. 2, the details of C section are the mounting state of the steady rest 8 at the bottom of the ball screw 3, the guide bush 16 for receiving the moment load applied to the outer cylinder 1 by the inner cylinder 2, and the detent for preventing the rotation of the outer cylinder 1. The attachment state of the key 9 is shown. The arrangement of upper and lower limit stop sensors 11a and 11b and detection rods 12a and 12b for electric drive is shown.

The load transmission from the inner cylinder 2 to the ground is made by the base plate 17, the four struts 18 and the slip stopper pad 19. In order to simplify the movement, the pad 19 may be changed to a caster with a stopper.

It is the front view, side view, and top view of the state where the operator sat down to the raising / lowering saddle for light work of the Example of this invention. The front view is a sectional view of the ball screw attached. It is A, B, and the C section detailed cross-sectional view shown to the front view of FIG. 1 of an Example of this invention.
