Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a guide tube in which an open groove of a constant width is formed in the axial direction, in which a long and slender driving member such as a cable or a rond is inserted freely in the axial direction, and is fixed to the driving member. The present invention relates to a window opening/closing device in which a connecting member is connected to a window plate through the opening groove, and the window plate is opened and closed by raising and lowering the window plate by sliding the driving member.

First, an example of a window opening/closing device using a gear cable in which meshing teeth are formed by spirally winding a metal wire around a core wire with equal pinches will be described with reference to the accompanying drawings.

A pair of side frames 1 having vertical guide grooves 2 formed on the corresponding inner surfaces are erected in parallel to each other, and a glass window plate 3 having both sides fitted into the guide grooves 2.2 is mounted to be freely raised and lowered. A closing plate 4 is stretched across the lower part between the side frames 1.1, and a certain space is provided between the mounting surface 4a on the inside thereof and the window plate 3. At the center of the mounting surface 4a of the closing plate 4,
U-shaped brackets 1-5 are fixed, one on top and one on top of A1.
At the same time, a circular gear case 6 is fixed to the side thereof with screws 7.7. As shown in FIG. 2, the gear case 6 has a circular gear housing hole 8 formed at its center, and a sliding hole 9 that intersects tangentially with the gear housing hole 8. A drive gear 13 housed in the hole 8 is fixed to a drive shaft 12, and one end of this drive shaft 12 penetrates the closing plate 4 and protrudes outward.
A handle 14 is attached.

A guide tube 15 having an axially formed open groove 18 opening on the window panel 3 side is passed through the upper and lower brackets 5.5 and is fixed by welding through the mounting piece 16.16. The guide tube 15 is fixed by a screw 17.
are connected in series, and their tips are connected to one end of the sliding hole 9 of the gear case 6, and the other end of the sliding hole 9 is connected to a terminal tube 2o whose tip is bent into a U-shape. .

Inside the straight pipe 15, the curved pipe 19, the sliding hole 9 of the gear case 6, and the terminal pipe 2o, there is a core wire 21 made of twisted metal.
A flexible guard cable 23, which has meshing teeth formed by spirally winding a single metal wire 22 at an equal pitch, is inserted freely into the sliding hole 9 at the intersection with the gear housing hole 8. As shown in FIG.
A connecting member 27 made of synthetic resin consisting of a ring 24, legs 25, and a mounting plate 26 is fixed to the gear cable 23 by casting it around the ring 24, and is fixed to the receiver of the window plate 3 by a screw 28 passed through the mounting plate 26. It is fixed at 29.

Then, when the handle 14 is turned to rotate the drive gear 3, the guard cable 23 that meshes with it moves in the axial direction and is connected to the guard cable 23 via the connecting member 27 and the receiver 29. The window plate 3 moves up and down along the guide tube j5 to open and close the opening above the closing plate 4. rHere, both sides of the window plate 3 are aligned with the guide grooves 2 of the side frame 1.
．． If the window plate 2 is tightly fitted, the window plate 3 will move up and down without shaking back and forth and left and right, but if the fitting accuracy is too strict, galling may occur and the window plate 3 may not move up and down smoothly. Therefore, a certain gap is often required between the window plate 3 and the guide groove 2, and in such a case, the window plate 3 will swing from side to side with play.

Therefore, in this embodiment, as shown in FIG. It is a contact surface 3o that makes sliding contact with the outer surface, and the contact surface 30 and the guide tube 15 allow the connecting member 27 to swing from side to side together with the window plate 3.
It is designed to be prevented by contact with

Note that if there is a possibility that the protruding piece 29 will interfere with the mounting piece 16 when the connecting member 27 moves to the upper or lower end of the guide tube 15, remove the interfering side of the mounting piece 16 and replace it with one of the mounting pieces. 16 may be fixed to the Brassino l-5, or the end of the projecting piece 29 on the interfering side may be driven in to shorten it.

In addition, if there is no interference with the mounting piece 16, the projecting piece 1
6 on both sides of the leg portion 25 to sandwich the guide tube 15 from both sides, the window plate 3 can be held more stably.

In the modification of the present invention shown in FIG. 5, arcuate contact surfaces 30a, 30a concentric with the outer surface of the guide tube 15 are formed on the inner surfaces of the protrusions 29a, 29a formed on both sides of the leg portion 25. This makes it possible to reliably prevent horizontal shaking.

In addition, instead of the guard cable 23, a simple wire,
It is clear that the present invention can also be applied to the case where a driving member such as a rod is used.

As specifically explained with the above embodiments, the window opening/closing device of the present invention has an elongated drive unit such as a cable or rod that slides in the axial direction within a guide tube in which an open groove of a constant width is formed in the axial direction. In the window opening/closing device, the window plate is temporarily connected to the window through the open groove with a connecting member that is freely inserted and fixed to the driving member, and the window plate is opened and closed by raising and lowering the window plate by sliding the driving member. The main feature is that the connecting member is formed with a contact surface that makes sliding contact with the outer surface of the guide tube, which has the effect of preventing the window plate from rolling and allowing the window plate to be stably raised and lowered.
