Description

[Detailed description of the invention] (Subject of the invention) This invention relates to a window that can be remotely opened and closed at any angle using a geared cable.

(Prior art and its drawbacks) Conventionally, geared cables have a strong pushing force inside the pipe, but a weak pushing force on the part that comes out from the pipe, and when pushed against a window shoji frame, it bends and becomes useless. Since the geared cable itself cannot be used to push the window, the pulling force of the geared cable is used to either open or close the window, and the opposite opening or closing requires manual effort. However, in this case, the window can only be opened or closed completely, and therefore the window cannot be opened or closed at any desired degree, nor can it be opened or closed remotely. To solve this drawback, there are combinations of geared cables and push-pull chains or gear racks, but these have complex structures and are expensive, and push-pull chains in particular apply forces in the right angle to the chain. The gear rack easily bends and becomes useless, and the rear of the gear rack sticks out when the window is closed, which is dangerous.
It has the disadvantage that its use indoors is restricted and its aesthetic appearance is impaired.

(Purpose of the invention) This invention improves the above-mentioned drawbacks of windows using conventional remote opening/closing devices, and has a simple and inexpensive structure that allows reliable remote opening/closing and stops the opening/closing degree of the window at a desired position. This was done to provide windows that can be opened and closed remotely.

(Structure of the device) This device connects the tip of a geared cable stored in a pipe.
The tip of the pipe is fixed to the sliding body that slides, and the coupling protrusion that projects from the sliding body is pivoted to one end of the push member that slides on the window frame, and the other end of the push member is
A shaft or hinge is used as a fulcrum to contact or pivot the shoji frame of a window that opens and closes, and a gear rotated by a manual handle or an electric motor is engaged with the geared cable.The rotation of the gear moves the geared cable forward and backward, and the sliding body moves forward and backward. The present invention relates to a remote opening/closing window in which the window can be opened and closed at any angle by pushing or pulling one end of the pushing member and lifting or lowering the shoji frame with the other end of the pushing member.

(Example) FIG. 1 shows an example of use in a skylight that opens upward.

The tip of the geared cable 2 housed in the pipe 1 is fixed by welding or other method to the bottom of the sliding body 3 consisting of the bottomed cylindrical body 3' shown in FIG. Insert it into pipe 1 from the edge,
The bottomed cylindrical body 3' and the pipe 1 are engaged with each other so that the bottomed cylindrical body 3' slides back and forth at the tip of the pipe 1 in accordance with the movement of the geared cable 2. The bottomed cylindrical body 3' may be engaged with the pipe 1 by inserting the tip end portion of the pipe 1 through the opening of the bottomed cylindrical body 3'. The bottomed cylindrical body 3' may have a structure that expands and contracts in two or more stages. In these engagements, when the tip of the geared cable 2 pushes the bottom of the bottomed cylindrical body 3' in the manner described later, the bottomed cylindrical body 3' is not separated from the tip of the pipe 1. It is preferable that both the bottomed cylindrical body 3' and the pipe 1 be provided with engaging protrusions that abut and lock with each other.

The bottomed cylindrical body 3' is pivoted to one end 5a of the push member 5 at a coupling protrusion 4 protruding from its outer bottom surface, and the other end 5b of the push member 5 is provided with a window that opens and closes using a shaft or a hinge as a fulcrum 6. It is pivoted to the shoji frame 7 at a position away from the fulcrum 6.

When the window is closed, the shoji frame 7 is parallel to the shoji frame 7.
Attach the crosspiece 8 to a roof, ceiling, wall, or pillar, etc., and place the pipe 1 and the bottomed cylindrical body 3' on the upper surface of the crosspiece 8 (in the figure) and parallel to the crosspiece 8. and attach the pipe 1 to the ceiling, roof, wall, pillar, etc. In this case, the pipe 1 may be bent except for the vicinity of the sliding portion of the bottomed cylindrical body 3'.

Contrary to the drawing, the bottomed cylindrical body 3' and the pipe are
That is, the bottomed cylindrical body 3' is connected to one end 5a of the pushing member 5.
It may be attached so that it is pushed from right to left in the figure.

On the top surface of the crosspiece 8 (in the figure), there is a support so that the one end 5a of the push member 5 does not come off the crosspiece 8 when it slides back and forth on the top surface of the crosspiece 8 (in the figure) due to the movement of the bottomed cylindrical body 3'. It is preferable to provide a groove in the groove.

A window frame may be used instead of the crosspiece 8.

A cutout is provided at an appropriate position on the pipe 1 to engage the gear with the geared cable, and an operating means for manually or electrically rotating the gear is attached. These use conventional known techniques and are omitted in the drawings.

One end 5a of the push member 5 is pressed so that the one end 5a of the push member 5 smoothly slides on the upper surface of the crosspiece 8 (in the figure).
A trochanter may be attached to the trochanter.

This idea can be used not only for skylights that open from the top, but also for windows that open from the bottom (the structure with the window fulcrum 6 facing upward in Figure 1), double-hung windows, and single-hung windows.

If the window is large, you may install a shoji frame on the opposite side of Figure 1 that has a structure that is symmetrical to that shown in Figure 1 and interlock it, or you can also add it to other positions. Can be installed.

As shown in FIG. 3, a rod-shaped body 3'' may be used as the sliding body 3 instead of the bottomed cylindrical body 3'.Also, the tip of the geared cable 2 is fixed to the bottomed cylindrical body 3'. In some cases, it may be fixed to the inner bottom surface of the bottomed cylindrical body 3', or it may be fixed to the outer bottom surface of the bottomed cylindrical body 3' by welding, caulking, or other methods.

In the embodiment shown in FIG. 4, the pushing member 5 is composed of two rods 9 and 10, and one end of the rod 10 is pivoted to the coupling protrusion 4, and the other end of the bar 10 is not pivoted to the shoji frame 7. One end is pivoted to the other end of the rod 9 which is pivoted to the crosspiece 8, and as the sliding body 3 advances and retreats, the lower end 10a of the rod 10 slides on the crosspiece 8, and the rod 10 and the rod 9 are pivoted to move up and down. The shoji frame 7 is pushed up or lowered depending on the section.

(Operation and effect of this invention) When opening this window, the gear is rotated by the operating means to slide the geared cable 2 toward the tip of the pipe 1, and the bottom of the sliding body 3 is touched with the tip of the geared cable 2. When pressed, one end 5a of the push member 5 or the lower end 10a of the rod 10 slides on the upper surface of the crosspiece 8 in the direction of the fulcrum 6 of the shoji board 7 (in FIG. 1) or in the opposite direction (in FIG. 4), and at the same time the push member 5 The other end 5b of 5 or the pivoted portion of rod 9 and rod 10 are lifted one after another, and the shoji frame 7 is lifted about fulcrum 6. When it is desired to half-open the window, if the rotation of the gear is stopped midway, the pivoting part between the push member 5 or the rod 9 and the rod 10 supports the shoji frame 7 while remaining half-open. To close the window, rotate the gear in the opposite direction using the operating means, and the geared cable will close the slider 3.
Since it is pulled, one end 5a of the pusher member 5 or the lower end 10a of the rod 10 is also pulled, and at the same time, the other end 5b of the pusher member 5 or the pivoted portion of the rods 9 and 10 pulls down the shoji frame 7, so that the window is closed. As mentioned above, if the rotation of the gear is stopped midway, the window can be opened in any desired half-open state.

As mentioned above, the remote opening/closing window of this invention has an extremely simple structure and operation compared to conventional ones, can be opened and closed remotely, can be left in any half-open state, and is inexpensive to manufacture and install. is possible,
In addition, there is no danger of the protrusion of the rear end of the gear rack in conventional opening/closing devices, and other excellent effects are achieved.
