Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control device for multiple movable members used for remote control of fenders and mirrors of automobiles.

The object of the present invention is to provide a compact hydraulically operated remote control device that sequentially switches and operates the operating cylinders of each movable member using one hydraulic cylinder type pump device.

In the present invention, an inner cylinder 2 having a handle 1 at its outer end is tightly fitted into an outer cylinder 3 attached to a base body so as to be rotatable only, and a hole is bored in the outer circumference of the bottom of the inner cylinder. A plurality of holes 5 and 6 to be communicated with each other are formed on the same circumference at the bottom of the outer cylinder, and the respective companies on the outer cylinder side are connected via piping to the actuating cylinder 7 of the corresponding movable member. A cylindrical piston 8 was fitted into the inner cylinder so that it could only slide freely, a piston rod 9 was screwed onto the piston 10, and the vicinity of the outer end knob 11 of the piston rod was attached to the inner cylinder 2 so that it could only rotate freely. The figure shows a case where the present invention is applied to a fender mirror remote control device, and the outer cylinder 3 has an outer end flange 12 and a nut 13 screwed into the outer cylinder. The wall plate-like base 14 in front of the driver's seat of the automobile is pressed between the two and fixed thereto.

Reference numeral 15 denotes a retaining ring for the inner cylinder 2, which is provided with a notch 15', and the retaining ring 15 fits into annular grooves formed near the outer ends of the inner and outer cylinders 2 and 3 so as to face each other. .

Reference numeral 16 denotes a plate-shaped gasket made of oil-resistant rubber that is fixed to the outer surface of the bottom of the inner cylinder 2 by adhesive or the like, and the gasket 16 comes into sliding contact with the bottom of the outer cylinder 3.

If there are two holes 5, 6, etc. drilled at the bottom of the outer cylinder,
Since the holes 6 other than the hole 5 communicating with the hole 4 do not communicate with other holes, the packing 16 only needs to be attached around the hole 4.

Reference numeral 16' denotes a projection on the back side of the packing 16. The projection 16' fits into a recess on the outer surface of the bottom of the inner cylinder to increase the positioning and rotation prevention function between the inner cylinder 2 and the packing 16.

17 is a conical recess formed in the outer end surface of the outer cylinder 3 corresponding to the position of each hole 5, 6, etc.; A supported steel ball 19 mounted so as to be retractable engages with the conical recess 17 to determine the rotational position of the inner cylinder 2.

A key part 20 is made to protrude in the radial direction from the base end of the cylindrical piston 8, and the key part 20 is engaged with a keyway 21 recessed in the inner cylinder 2, so that the piston rod 9 is attached to the cylindrical piston.
Cylindrical piston 8 when screwing in or unscrewing
Measure the rotation stop.

A retaining ring 22 having a notch 22/ is fitted into an annular groove formed oppositely between the knob portion 11 fixed to the outer end of the piston rod 9 and near the outer end of the inner cylinder 2.
A knob part 11 is supported by an inner cylinder 2 so as to be rotatable only.

In the figure, 23 is a gasket such as a 01J ring installed on the inner cylinder 2 side so as to be inscribed in the outer cylinder 3, and 24 is a gasket attached on the cylindrical piston 8 side so as to be inscribed in the inner cylinder.
25° 26 indicates flexible piping between the outer cylinder 3 and the working cylinder 7, and the end of the working cylinder 7 on the side where the piston rod 27 is inserted is pivoted 29 on the base plate 28, and the piston The tip of the rod 27 is pivoted 32 to the back plate of a mirror (movable member) 31 which is pivoted 30 to the base plate.

A return spring 33 is attached to the mirror pivot shaft 30 so as to constantly push and bias the piston rod 27 into the operating cylinder 7.

The plywood 28 has a circular mound-shaped portion 28' that protrudes from the back side thereof.
The mirror cover 34 is shown removably clamped by a C-shaped spring 35 installed inside the mirror cover 34.

The present invention has the above-mentioned configuration, in which the inner cylinder 2 is rotated by the handle 1 and the hole 4 thereof is communicated with the hole (5 in the figure) on the outer cylinder side which communicates with the actuation cylinder 7 of the required movable member (mirror). Next, the piston rod 9 is rotated left and right by the knob 11 to slide the cylindrical piston 8 screwed onto the piston rod 9 within the inner cylinder, thereby draining the oil in the oil chamber 36 within the inner cylinder 2. Oil chamber 3 is sent to the hole 5 or from the reading plate 5.
Oil is sucked into the cylinder 6 to control expansion and contraction of the operating cylinder 7.

According to the present invention, the cylindrical piston 8 has a threaded portion with the piston rod 9 and the piston rod 9 is connected to the inner cylinder 2.
Since sliding is prevented by the inner cylinder through the retaining portion, the cylindrical piston 8 will not slide relative to the inner cylinder 2, regardless of the level of pressure in the hydraulic system, unless the knob portion 11 is operated. , and since the oil chamber volume of the hydraulic system does not change regardless of the rotation of the inner cylinder 2 relative to the outer cylinder 3,
There is no fear that the movable parts will move due to the rotation of the inner cylinder 2.
Therefore, the selection handle part 1 and the operating knob part 11 of the movable member
can be operated alternately, and since the handle portion 1 and the knob portion 11 are provided on the same axis, there is an effect that the operation side of the remote control device can be made compact.
