Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a door switch. More specifically, the present invention relates to a door opening/closing device that can hold a double-folding window or door at an arbitrary opening degree and requires a small installation space.

[Prior Art] As a conventional door switch, there is one shown in FIG. 18, for example. This switch D consists of a stay 53 that is rotatably attached to the window 51 side with a mounting bracket 52 and a stopper 55 that is fixed to the window frame 54 side.If you turn the screw 56 on the top of the stopper 55 with your finger, the stay 53 slides through a hole in the stopper 55, and the stay 53 is fixed in the stopper 55 by turning the screw 56 in the opposite direction.

When in use, when the screw 56 is turned and the window 51 is pushed and pulled, the stay 53 follows suit and the window 51 is opened and closed, and when the screw 56 is tightened in the middle of opening and closing, the stopper 55 is activated. The window 51 is adapted to be held in its open and closed position.

[Problems to be solved by the invention] In conventional door openers, the stay 5 can be moved at any position.
3 is difficult to secure, and there is a problem in that the window suddenly closes or opens suddenly when the wind blows.

In view of such circumstances, the present invention aims to provide a door opening/closing device that can reliably hold windows and doors at arbitrary opening degrees.

[Means for Solving the Problems] The door opener of the present invention includes an elongated outer cylinder having a plurality of engagement recesses along its longitudinal direction, and a long outer cylinder that is telescopically inserted into the outer cylinder. an elongated inner member, an engagement member having a base fixed to the inner member and a plate spring member whose engagement portion can elastically engage with the engagement recess; Fitted into the outer cylinder so as to be slidable along the longitudinal direction of the cylinder, and having a pressing part;
A locking mechanism that can be locked by being slid by the pressing portion to a position where the engaging member is pressed and fixed in a state in which it is engaged with the engaging recess, and a locking mechanism that is formed on the insertion member. The stopper is comprised of a convex stopper that can be elastically engaged with a convex portion formed on the locking mechanism when the mating member is in the locked state and in the unlocked state.

Note that the door operating device of the present invention can be applied to windows, doors, and other types of doors that open on double doors in general. However, in this specification, unless otherwise specified, "window" refers to all types of double-hung windows, doors, and doors, and "window frame" is used to refer to their frames. There is.

[Function] The present invention has a locking mechanism that can lock the engagement member at any position within the outer cylinder,
They engage and act on the stopper formed on the inner member, so when the locking mechanism is activated,
Even when the wind blows, the windows do not close or open on their own.

[Example] Next, embodiments of the present invention will be described.

Fig. 1 is a perspective view of a switch according to an embodiment of the present invention in an installed state, Figs. 2 and 3 are a plan view and a front view of the switch, and Figs. 4 and 5 are a plan view and a portion of an outer cylinder. A perspective view, FIGS. 6 and 7 are a plan view and a partial perspective view of the inner member, FIGS. 8 and 9 are explanatory views of the inner member inserted into the outer cylinder, and FIG. 10 is a main part of the switch. A perspective view, FIGS. 11-12 are a vertical cross-sectional view and a schematic plan view with the lock mechanism released, and FIGS. 13-14 are a vertical cross-sectional view, a schematic plan view, and a schematic plan view with the lock mechanism in operation. Fig. 15 is a perspective view of a switch according to another embodiment of the present invention, and Figs. 16 and 17 are a plan view and a front view of the switch.

In Figures 1 to 3, 1 is a switch, 2 is a window, and 3
is the window frame.

The switch 1 has an elongated outer cylinder 5 and an elongated inner member 6, and can be attached to the window frame 3 and the window 2 using attachment fittings 7 and 8. In addition, the mounting bracket 7,
8 can be of any shape depending on the window 2 and window frame 3 to be installed; for example, the first
5 to 17 may be used. The mounting bracket 8a shown in this figure is of a type that allows the insertion member 6 to be attached to the lower notch of the window 2 from the back side.

The outer cylinder 5 will be explained based on FIGS. 4 and 5. The outer cylinder 5 has a wide cross-section over most of its longitudinal direction. Side walls 11 on both sides of the outer cylinder 5 extend straight in the longitudinal direction, and upper edges 11a of the side walls 11 extend slightly inward. The edge of the upper edge 11a is formed into a continuous wave shape. Note that at the end of the upper edge 11a, the protruding piece 11b is bent inward and diagonally downward to prevent the insertion member 6 from coming off. It is preferable to form the outer cylinder 5 by press working from a metal such as iron, stainless steel, or aluminum in order to maintain sufficient strength and manufacture it at low cost.

The inserting member 6 will be explained based on FIGS. 6 and 7. The inner member 6 is a long member of the same size as the outer cylinder 5, and has a cross-sectional shape and dimensions that allow it to be telescopically inserted into the outer cylinder 5. The illustrated inner member 6 has a wide cross-section, and like the outer cylinder 5, it can be manufactured by press working from metal such as iron, stainless steel, or aluminum to achieve sufficient strength and low cost. It is preferable to do so.

An engagement member made of a leaf spring 9 is attached near one end of the insertion member 6. This leaf spring 9
consists of a mounting part 9a and an engaging part 9b, and the mounting part 9
A has a U-shaped cross section and is fixed to the bottom surface of the insert member 6 by a rivet 9c. Engagement part 9
b consists of a thin spring plate extending from the mounting portion 9a, the tip of which is wound into a cylindrical shape, into which a headed pin 9d is inserted from below. This pin 9d functions to prevent the cylinder of the engaging portion 9b from being crushed even if force is applied during locking. The engaging portions 9b face the cutout portions 13 on both sides of the inner member 6, and are designed to elastically engage with the corrugation of the upper edge 11a of the side wall 11 of the outer cylinder 5. In other words, the leaf spring 9 is bent inward when an external force is applied, and is able to climb over the peaks of the upper edge 11a of the corrugated side wall 11. Note that a plate 6b is fixed to the rear part of the attachment part 9a of the plate spring 9.
It comes into contact with the protruding piece 11b of the outer cylinder 5 and functions as a stopper to prevent the inner member 6 from coming off.

8 and 9 show the state in which the inner insertion member 6 is inserted into the outer cylinder 5. In FIG. 8, the inner member 6 is deeply inserted into the outer cylinder 5, and in FIG. 9, the inner member 6 is almost pulled out from the outer cylinder 5. When the inner member 6 is moved in the longitudinal direction within the outer cylinder 5 in this way, the leaf spring 9
It is moved by repeatedly engaging and disengaging from each waveform of a.

The locking mechanism is shown in Figures 10-14. This locking mechanism locks or releases the engagement of the leaf spring 9 at any position within the outer cylinder 5, and includes an inner member 6 and a rectangular cylindrical knob member 15 placed over the outer cylinder 5. is established between.

As shown in FIG. 10, a first stopper 16, which is formed by cutting out the bottom plate 6a of the inserting member 6 and bending it diagonally upward, is provided at the distal end of the inserting member 6;
A second stopper 17 formed by raising the bottom plate 6a upward is provided slightly inside the stopper 16. An arrow 18 indicating the locking direction is formed on the surface of the box of the knob member 15.
A wedge 19 is formed on the inner surface of the box. The wedge 19 is inserted between the two engaging portions 9b of the leaf spring 9 to prevent the engaging portion 9b from bending inward. A convex portion 21 connected by a connecting piece 20 is integrally formed at the rear of the wedge 19. Note that the grip member 15 having the wedge 19 and the convex portion 21 is preferably integrally molded from synthetic resin, aluminum die-casting, or the like.

11-12 show the unlocked state, and FIGS. 13-14 show the locked state. Note that in FIGS. 12 and 14, only the wedge 19 and the convex portion 21 of the knob member 15 are shown with hatching in order to make the positional relationship easier to understand.

Unlocked state (Figures 11-12)
, the convex portion 21 is connected to the first stopper 16 and the second stopper 16.
The wedge 19 is located between the stopper 17 and the wedge 19 is not in contact with the leaf spring 9. Therefore, since the leaf spring 9 can be freely bent, the inner member 6 can freely expand and contract within the outer cylinder 5 when the knob member 15 is in the illustrated position. Note that since the protrusion 21 of the knob member 15 is in contact with the first stopper 16, the inner member 6
It never goes away.

From the above state, by moving the knob member 15 with your finger in the direction of the arrow 18 formed on its surface, it can be brought into the locked state (FIGS. 13 and 14). When the knob member 15 is moved, the connecting piece 20 is bent and the convex portion 21 passes over the second stopper 17 and is restrained in the illustrated state. At this time, the wedge 19 fits between the two engaging parts 9b of the leaf spring 9, and the leaf spring 9 cannot be bent, so that the state in which the engaging part 9b is engaged with the recess in the side wall 11 of the outer cylinder 6 is maintained. Retained. Therefore, in this state, the leaf spring 9 is restrained at the position where it engages with the side wall 11 of the outer cylinder 5, and cannot freely expand and contract with respect to the outer cylinder 5.

Next, the actions of the switch 1 as described above will be explained in steps 1 to 3.
This will be explained with reference to the figures. If the grip member 15 is pulled in the direction opposite to the direction of the arrow 18, the insert member 6 will be removed.
Since the window 2 freely expands and contracts with respect to the outer cylinder, the window 2 can be opened and closed freely by holding and moving the window 2 by hand. that time,
Since the inner member 6 only moves in and out of the outer cylinder 5, the switch does not protrude inside the window frame 3. When the knob member 15 is moved in the direction of the arrow 18 with the window 2 open, closed, or partially opened, the locking mechanism is activated and the movement of the insert member 6 is restrained. Therefore, the window 2 remains open, closed, or partially opened. Moreover, when the window 2 tries to open or close due to an external force, that force is converted into a force that pushes the two engaging parts 9b of the leaf spring 9 inward, but that force is absorbed by the wedge 19. Since no force is ever generated in the direction of expansion and contraction of the insertion member 6, it is mechanically reasonable and extremely strong. Therefore, even if the wind blows,
The inconvenience of the window 2 being opened or closed unexpectedly does not occur. Furthermore, with this invention, the switch does not protrude inward when the window is opened or closed.
This has the advantage that it requires only a small installation space, and that you can freely install other internal windows on the inside of the window.

[Effects of the invention] According to the invention, the window can be opened to any desired opening degree and reliably maintained in that state.
