Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a switch such as a door. More specifically, a window or door such as a skylight for air intake can be securely held at a desired position, and even if the user touches an open window or door, the window closes or moves without permission. The present invention relates to a switch such as a door which can be locked so as not to be locked.

[0002]

2. Description of the Related Art Conventionally, various types of switches such as doors for fixing a window or a door such as a skylight for air intake to a fully open position or a desired half-open position have been used. Known from. For example,
2. Description of the Related Art There is known a switch such as a door having an outer arm and an inner arm, both of which are slidably connected and further provided with a ratchet mechanism for fixing the inner arm at an appropriate position. Such a conventional switch such as a door is attached to each side of a skylight, for example. Specifically, the front end of the inner arm is attached to the skylight, and the rear end of the outer arm is attached to the window frame.

However, when the door or the like is opened and the door or the like is completely extended,
There is a problem that durability is poor because an impact acts directly on the connecting portion between the inner arm and the outer arm.

Therefore, the present inventor has previously proposed a switch such as a door which can eliminate the impact of the connecting portion (Japanese Patent Application No. 2-4).
No.00628). Such a switch such as a door has an outer arm and an inner arm, the front end of the inner arm is inserted from the rear end of the outer arm, and both are slidably connected,
It has a fully open lock mechanism and a half open lock mechanism.

[0005] The fully-open lock mechanism includes a locking body having a locking portion rotatably attached to a front end side inside the outer arm, and a locking body provided at a rear end side inside the inner arm. And a contact body that can contact the body.

[0006] Further, elongated holes are formed on the front end side of the outer arm and the rear end side of the upper surface of the inner arm so that the locking portion of the locking body can protrude and retract.

The half-open lock mechanism includes a rack having teeth arranged inside the outer arm along a longitudinal direction, and a rear end inside the inner arm so as to be biased toward the rack. And a detent having a claw attached to the side.

When such a switch such as a door is used, first, when the inner arm is pulled out substantially the entire length from the outer arm by fully opening the window or the like, the contact body on the rear end side of the inner arm moves outward. The locking body is rotated by contacting the locking body of the arm. At this time, the locking body slightly appears to the outside through the long holes of the inner arm and the outer arm, and locks in a substantially fully opened state so that the inner arm cannot be inserted into the outer arm.

When it is desired to close the window from the fully opened state, the window is further opened and the inner arm is further pulled out, so that the abutting member comes into contact with the locking member and the locking member is further rotated to thereby rotate the inner arm. The lock can be released and the window can be closed as a result.

Also, while opening the window, the detent claw of the outer arm continuously meshes with the teeth of the rack of the inner arm, so if the opening of the window is stopped halfway,
The window can be locked in the desired half-open position.

However, in the case of a switch such as a door having a fully-open lock mechanism and a half-open lock mechanism as described above, the window is opened when a force is inadvertently applied to the window in either the half-open state or the fully-open state. It has the disadvantage of moving.

In particular, when the window is fully opened, when the window is cleaned, or when a head or the like of a person working around the window applies a force in a direction in which the window hits the window and pushes the window open, the above-described operation is performed. As described above, the locking of the inner arm by the locking body is released, and the window may be inadvertently closed.

The present invention has been made in order to solve such a problem, and a window or a door such as a skylight for air intake can be securely held at a desired position, and a user is open. An object of the present invention is to provide a switch such as a door which can be locked so as not to close or move without permission even when touching a window or a door.

[0014]

A switch such as a door according to the present invention comprises:
An outer arm and an inner arm, wherein a front end of the inner arm is inserted from a rear end of the outer arm, the two arms are slidably connected to each other, and a fully-open lock mechanism and a half-open lock mechanism are provided. A lock mechanism may be in contact with a locking body having a locking portion rotatably attached to a front end side inside the outer arm and the locking body provided at a rear end side inside the inner arm. A long hole through which a locking portion of the locking body can be protruded and retracted is formed at a front end side of the outer arm and a rear end side of an upper surface of the inner arm. A rack having teeth disposed along the longitudinal direction inside the inner arm, and meshing with teeth of the rack attached to the front end of the outer arm so as to be biased toward the rack; Has nails that can be A door or other switch including a detent, wherein at the front end side inside the outer arm, the movement of the detent can be regulated, and the inner arm is fixed to a position at the time of full opening inside the outer arm. A stopper that can be provided.

Further, the locking member of the outer arm has a compensating mechanism for compensating the moving distance of the rotating shaft and the inner arm, and the compensating mechanism can rotate the rotating shaft of the locking member. A holding plate for holding the holding member, a guide plate having an elongated hole for slidably supporting the rotation axis of the locking member along the longitudinal direction of the outer arm, and It is preferable that the arm comprises a spring for urging the arm toward the rear end.

According to the present invention, since the stopper is provided on the front end side inside the outer arm, the inner arm can be reliably locked at the predetermined position when the arm is fully open or half-open. For example, if the stopper is operated when the window is fully opened, the stopper can lock the inner arm in the fully opened position. In addition, if the stopper is operated when the window is half-opened, the stopper restricts the movement of the detent, so that the detent claw cannot move while meshing with the teeth of the rack on the inner arm side. , The inner arm can be locked in the half-open position.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a switch such as a door according to the present invention. FIG. 1 is a perspective explanatory view showing a use example in which both sides of a skylight are supported as one embodiment of a switch such as a door of the present invention. FIG. 2 is a perspective view showing a state where a side cover of an outer arm of FIG. 1 is opened. 3 is a partially cutaway perspective view of the inner arm of FIG. 1, FIG. 4 is an exploded perspective view of a main part of the compensation mechanism of FIG. 2,
5 to 12 are sectional explanatory views showing the operation of the switch such as the door in FIG. 1.

As shown in FIG. 1, the switch such as a door of this embodiment applied to the skylight W has an outer arm 1 and an inner arm 2, and the inner arm 2 extends from the rear end of the outer arm 1. Are inserted so as to be slidable. Both sides of the skylight W are connected to the window frame F via such door switches. The switch such as a door includes a full-open lock mechanism and a half-open lock mechanism, which will be described later, to lock the skylight W in a fully-opened or partially-opened state. A lever 6 for operating the stopper 5 (see FIG. 2) protrudes to the outside at the front end side of the outer arm 1.

The outer arm 1 is, as shown in FIG.
A base 1a and a side cover 1b each having a substantially U-shaped cross section formed by bending a metal plate of stainless steel, aluminum, steel, iron, or the like so as to have a substantially U-shaped cross section are fitted to face each other. By combining them, a cylindrical body having a rectangular cross-sectional shape is obtained.

A detent 3 having a claw 3a at its tip is rotatably attached to a mounting plate 1e provided on the front end 1c side inside the base 1a. Since the detent 3 is pulled by the extension coil spring 4 from the rear end 1d side of the outer arm 1, the claw portion 3a is constantly urged in the direction of pressing against the rack 13 (see FIG. 3) of the inner arm 2. I have. The rear end side of the tension coil spring 4 is locked on a guide plate 16 (see FIG. 4).

Further, a stopper 5 is provided on the mounting plate 1e.
Is rotatably mounted. The stopper 5 is made of a metal plate-like member, and has a contact portion 5 a having a substantially sector shape that can contact the side surface of the detent 3, and a fitting hole 12 (see FIG. 3) formed on the upper surface of the inner arm 2. (See FIG. 3) are formed respectively. One end of a lever 6 is fixed to a peripheral portion of the stopper 5. The grip 6a formed at the other end of the lever 6 is exposed to the outside through an elongated hole 7 formed by cutting out the base 1a and the side cover 1b.

A locking body 8 having four locking portions 8a formed diagonally is rotatably mounted on a mounting plate 1f provided on the front end 1c side inside the base 1a. On the front end 1c side of the outer arm 1, a locking portion 8 of the locking body 8 is provided.
A long hole 9 through which a can appear is formed by cutting out the base 1a and the side cover 1b. Further, the locking body 8 of the outer arm 1 includes a compensating mechanism 14 described later for compensating the moving distance of the rotating shaft 8b and the inner arm 2.

Inside the outer arm 1, the mounting plate 1
e, 1f and a spring stopper 1g described later are erected from the bottom surface 1j so as to form a gap G between the inner inner surface 1h of the base 1a. By inserting one side wall 2d (see FIG. 3) of the inner arm 2 through the gap G, the inner arm 2 can slide inside the outer arm 1.

The inner arm 2 is, as shown in FIG.
It is manufactured by bending a metal plate such as stainless steel, aluminum, steel, or iron so as to have a substantially U-shaped cross section. At the front end 2b inside the inner arm 2, a tooth 1
A rack 13 on which 3a is formed is provided. Also,
On the rear end 2c side of the inner arm 2, there is provided a contact body 10 which can contact the locking body 8 on the outer arm 1 side. Further, a long hole 11 is formed at the rear end side of the upper surface of the inner arm 2 so that the locking portion 8a of the locking body 8 can protrude and retract, and the stopper 5 is provided at a position forward of the long hole 11. A fitting hole 12 into which the fitting protrusion 5b (see FIG. 2) can be fitted is formed.

Next, the fully open lock mechanism and the half open lock mechanism will be described.

As shown in FIGS. 2 and 3, the full-open lock mechanism includes a front end locking member 8 inside the outer arm 1 and a rear end contact member 10 inside the inner arm 2. ing. On the other hand, a locking portion 8a of the locking body 8 is provided on the front end 1c side of the outer arm 1 and the rear end 2c side of the inner arm 2.
Long holes 9 and 11 are formed respectively.
Therefore, when the skylight W of FIG. 1 is opened almost to the full open state and almost the entire length of the inner arm 2 is pulled out from the outer arm 1, the contact body 10 rotates the locking body 8, and The locking portion 8a is protruded outside through the elongated holes 9 and 11 (see FIG. 8). This prohibits the inner arm 2 from being housed inside the outer arm 1 and, as a result,
The skylight W is locked in the fully opened state (see FIG. 9). Also,
When it is desired to close the skylight W from the fully opened state, the skylight W is further opened and the inner arm 2 is further pulled out, so that the contact body 10 comes into contact with the locking body 8 and the locking body 8 is further rotated. The lock of the inner arm 2 is released (see FIG. 10), and as a result, the skylight W can be closed.

As shown in FIGS. 2 and 3, the half-open lock mechanism has a rack 13 having teeth 13a on the inner arm 2 side, and a claw 3a capable of meshing with the teeth 13a of the rack 13. And a detent 3. With this configuration, as shown in FIG.
Is moved forward (that is, the direction of opening the skylight W in FIG. 1 and the rightward direction in FIG. 6), the claws 3a only slide on the teeth 13a and do not mesh with each other. Even when the arm 2 is to be moved rearward (that is, in the direction to close the window and to the left in FIG. 6), the claw 3a engages with the teeth 13a, and the inner arm 2 is housed inside the outer arm 1. Is forbidden. Therefore, the window can be locked in a half open state at a predetermined position.

As shown in FIG. 2 and FIG. 4, a compensating mechanism 14 provided in the locking body 8 is a holding body for rotatably holding the rotating shaft 8b of the locking body 8. 1
5, and a long hole 16a for slidably supporting the rotation shaft 8b of the locking body 8 along the longitudinal direction of the outer arm 1.
Are formed, and a tension coil spring 17 for urging the holding body 15 toward the rear end 1d of the outer arm 1. Extension coil spring 17
The rear end side is locked by the spring stopper 1g. Since the compensating mechanism 14 allows the locking body 8 to move in the longitudinal direction of the outer arm 1, the compensating mechanism 14 can compensate the moving distance of the inner frame 2 when releasing the full-open lock mechanism.

For example, as shown in FIG. 1, in the case of a skylight W on which the switch such as a door of this embodiment is attached to both sides, it is necessary to release the lock from a state in which the switch is fully opened by the fully open lock mechanism. It is necessary to release the lock by pulling out the inner arms 2 of the switches such as doors on both sides by a predetermined length. However, if only one side of the skylight W is pushed to pull out the inner arms 2 on both sides, the skylight W is slightly curved. The lock can be released by pulling it out, but on the other side of the skylight W, the inner arm 2 cannot be pulled out by a predetermined length, and there is a case where the lock cannot be released. In this case, the lock must be released by pressing only the other side of the skylight W again. In order to solve such a problem, the switch such as the door of the present embodiment is provided with the compensating mechanism 14, so that with respect to one side of the skylight W, the inner arm 2 is pulled out by a predetermined length to release the lock. After that, the locking mechanism 8 and the inner arm 2 are further moved forward by substantially the length of the long hole 16a by the action of the compensating mechanism 14 (see FIG. 12). On the other side of W, the inner arm 2 can be sufficiently pulled out by a predetermined length, and the lock can be released.

Although the present embodiment has been described with reference to an example in which the locking member has a compensation mechanism, the present invention is not limited to this. For example, when only one switch such as the door of the present invention is attached to a window or a door, a compensating mechanism is not always necessary, but if it is provided, a kind of cushion is provided when it is opened vigorously. Plays the role of
This has the effect of preventing doors and hinges from being damaged.

Next, an operation method of the switch such as a door according to the present embodiment will be described in order with reference to FIGS.
5 to 12, the right side in the figures is the front, and the left side is the rear.

First, as shown in FIG. 5, when the skylight W in FIG. 1 is in the fully closed state, the inner arm 2 is housed in the outer arm 1 substantially the entire length, and the detent 3 is engaged with the rack 13. I haven't. At this time, if the lever 6 is at the position indicated by the solid line in FIG. 5, the inner arm 2 can move forward. However, if the lever 6 is tilted to the position indicated by the imaginary line in FIG. The inner arm 2 cannot move forward because 5a restricts the rotation of the detent 3 in the counterclockwise direction and inhibits the detent 3 from engaging with the rack 13.

Next, as shown in FIG. 6, as the skylight W is opened, the inner arm 2 is pulled out from the inside of the outer arm 1, and the detents 3a are attached to the detents 3a by the teeth 13a of the rack 13. Meshes continuously. At this time, if the lever 6 is at the position indicated by the solid line in FIG.
The inner arm 2 can move forward, but if it is tilted to the position indicated by the imaginary line in FIG.
Abuts against the detent 3 so that the claw 3a of the detent 3 cannot release the engagement with the tooth 13a which is engaged at that time. As a result, the inner arm 2 can move forward. As a result, the skylight W can be securely locked at the desired half-open position.

Further, as shown in FIG. 7, when the skylight W is opened almost to the full open state, the long hole 9 of the outer arm 1 is opened.
And the long hole 11 of the inner arm 2 passes directly. At this time,
The contact body 10 on the rear end 2c side of the inner arm 2 abuts on the lower locking portion 8a of the locking body 8 on the front end 1c side of the outer arm 1.

Further, as shown in FIG. 8, when the skylight W is opened, the abutting member 10 rotates the locking member 8 in the counterclockwise direction. The upper locking portion 8a is projected outside. At this time,
The rack 13 finishes passing through the detent 3. When the upper locking portion 8a protrudes to the outside, the contact body 10 engages with the lower concave portion 8c of the locking body 8. The impact at the time of contact between the contact body 10 and the locking body 8 is very small because the compensation body 14 allows the locking body 8 to move slightly forward.

Then, as shown in FIG. 9, the skylight W is slightly closed and the inner arm 2 is slightly pushed into the outer arm 1 so that the peripheral portion of the long hole 11 of the inner arm 2 The inner arm 2 is locked by the upper locking portion 8a, and cannot move further into the outer arm 1. as a result,
The skylight W can be locked at the almost fully open position. At this time, if the lever 6 is tilted to the position shown by the imaginary line in FIG.
Since the fitting protrusion 5b of the stopper 5 fits into the fitting hole 12 of the inner arm 2, the inner arm 2 cannot be pulled out from the outer arm 1. Therefore, even when the user's head or the like hits the skylight W and applies a force in a direction to push the skylight W open when the skylight W is fully opened, the lock of the inner arm 2 by the locking body 8 is not released, There is no problem that the skylight W is closed carelessly.

When it is desired to close the skylight W from the fully open state, the lever 6 is operated to release the lock by the fitting projection 5b of the stopper 5 as shown in FIG. When the arm 2 is further pulled out, the contact body 10 comes into contact with the side surface of the locking body 8 to rotate the locking body 8 further counterclockwise to release the lock of the inner arm 2. In addition, even when it is difficult to release the switches such as the doors on both sides of the skylight W at the same time, since the doors and the switch of the present embodiment include the compensation mechanism 14 (see FIG. 4), the skylight W
As shown in FIG. 12, after the inner arm 2 is pulled out by a predetermined length to release the lock, the locking member 8 is further actuated by the action of the compensation mechanism 14.
By moving the inner arm 2 forward by approximately the length of the long hole 16a, even if the skylight W is slightly curved, the other side of the skylight W can also pull out the inner arm 2 by a predetermined length. , Can be unlocked.

Thereafter, as shown in FIG. 11, when the inner arm 2 is moved into the outer arm 1 while closing the skylight W, the peripheral portion of the long hole 11 of the inner arm 2 is The skylight W can be closed by rotating the locking body 8 in a counterclockwise direction while making contact.

In the present embodiment, the skylight W for taking in air has been described as an example of use of the switch such as the door of the present invention. However, the present invention is not limited to this.
The present invention can also be suitably applied to windows, doors, and the like of lids, bay windows, rotating windows, inspection doors, and the like of underfloor storages that need to be arbitrarily fixed at other half-open or fully-open positions.

[0040]

According to the present invention, a window or a door such as a skylight for air intake can be reliably held at a desired position, and even if the user touches the opened window or door, It can be closed or locked so that it does not move.
