Description

The present invention relates to a crescent sensor unit that is used by being attached to a sash frame or the like, detects the open / closed state of the sash and the locked / unlocked state of the crescent lock, and simultaneously locks the crescent lock.

Conventionally, a detection unit is installed near a crescent lock provided on a pair of sliding doors that run backwards, and a monitoring system for sliding doors is formed by this detection unit and a centralized management unit to which signals are input. The detection unit includes a control unit, a reed switch that is turned on and off in a closed state and a sliding door opened state, a crescent lock locked state, and an unlocked state. And a reed switch that is switched on and off, and when one of the reed switches is switched, the control unit is used to inform the centralized management unit which reed switch has been switched (for example, , See Patent Document 1).
Japanese Patent Laid-Open No. 10-61273

However, in the above conventional example, the reed switch only detects the magnet attached to the lever of the crescent lock, and the lever of the crescent lock itself is exposed. Normally, the crescent lock lever is locked by a slide-type operation unit provided in the vicinity of the rotation shaft of the lever. Whether the operation unit is in the lever lock state or in the lever lock release state. In order to detect whether it is, it was necessary to add a dedicated detection unit.

For this reason, in the past, it was possible to determine whether the sliding door was closed, opened, crescent lock locked, or unlocked, but the crescent lock lever lock It was not possible to determine whether or not Also, since the operation of locking the crescent lock is separate from the operation of locking the lever of the crescent lock, the operation of the crescent lock is complicated and the lock operation of the lever is often forgotten. The problem remains that the lever locking mechanism is not being used effectively.

In the present invention, a crescent sensor unit is constituted by a base portion and a main body that moves while being supported by the base portion, and the main body is within a range that does not hinder the operation of the lever of the crescent lock before moving from the base portion. After moving, the movement of the lever of the crescent lock stopped at the locking completion position is held at a position where it is physically blocked. The main body was provided with a reed switch for detecting a sash opening / closing detection magnet approaching in the closed state of the sash and a lever detection unit for detecting a crescent lock lever stopped at the locking completion position.

According to the configuration of the present invention, since the main body of the crescent sensor unit physically prevents the movement of the lever of the crescent lock, the lock function of the lever of the crescent lock is exhibited. Since the main body of the crescent sensor unit comes into contact, various means can be adopted as the position detecting means of the lever of the crescent lock stopped at the locking completion position. The magnet attached to the lever of the crescent lock is not caught by the conventional example that the reed switch detects, and the degree of freedom in design increases.

Furthermore, in the conventional example where the reed switch detects the magnet attached to the lever of the crescent lock, the length and shape of the lever of the crescent lock are limited, and it is not possible to handle the crescent lock with a short lever. However, according to the present invention, since the main body side of the crescent sensor unit moves, one that can be applied to crescent locks of various shapes including the length of the lever is realized.

FIG. 1 is a perspective view showing a state in which the crescent sensor unit of the present invention is attached to a sash with a crescent lock, and FIG. 2 is an enlarged view of a main part of FIG. 2A shows a state in which the crescent lock is in an unlocked state and the main body of the crescent sensor unit is fixed to the base portion, and FIG. 2B shows a state in which the crescent lock is in a locked state, and the crescent sensor is in a locked state. It shows a state where the main body of the unit physically blocks the movement of the lever of the crescent lock stopped at the locking completion position. 1 and 2 both show a state in which the sash is closed. This will be described in more detail with reference to FIG.

The crescent sensor unit includes a main body 1 and a base portion 2, and the main body 1 is supported on a base portion 2 screwed to a sash frame. In the state of (a), the lever 4 of the crescent lock can freely rotate, and this lever rotates and faces completely upward, and does not come into contact with the main body 1 of the crescent sensor unit even in the locked state. The state of (b) shows that the crescent lock is locked, the main body 1 moves while being supported by the base portion, and is held at a position surrounding most of the lever 4 of the crescent lock stopped at the locking completion position. ing.

The inside of the main body 1 is shown in FIG. A reed switch 5 for detecting the sash opening / closing detection magnet 3 approaching in the closed state of the sash and a lever detector 6 for detecting the crescent lock lever 4 stopped at the locking completion position are incorporated. The reed switch 5 does not react to the sash opening / closing detection magnet 3 in the state (a), but reacts to the sash opening / closing detection magnet 3 until it enters the state (b) so that the contact is turned on. Is set to Two reed switches 5 are provided so that the sash opening / closing detection magnet 3 can correspond to a mounting state in which the sash opening / closing detection magnet 3 approaches the surface opposite to the main body. The lever detector 6 is a contact switch that is activated by the contact of the lever 4 of the crescent lock, and is set so that the contact is turned off in the state (a) and the contact is turned on in the state (b). The main body 1 includes a wireless transmission unit that outputs the state of the reed switch 5 and the lever detection unit 6, and is set to emit radio waves toward the corresponding wireless reception device.

According to the above configuration, the open / closed state of the sash is detected by the reed switch 5, and the locked / unlocked state of the crescent lock is detected by the lever detection unit 6. Along with detection of the locked / unlocked state of the crescent lock, the main body 1 of the crescent sensor unit surrounds the lever 4 of the crescent lock, so that the lock function of the crescent lock also works.

The above description is for a crescent lock with a reasonably long lever. The lever of the crescent lock unit with a rectangular opening slides downward when the crescent lock lever is in a locked state. However, if the crescent sensor unit body is configured to move further downward, the crescent lock is such that the lever is short and the lever is within the dimensions of the mounting base. Is also applicable. For example, the opening of the main body of the crescent sensor unit may be a U shape instead of a rectangle so that it does not contact the lever mounting base. Movement of the main body of the crescent sensor unit from the base is not limited to the slide method. Before movement, the crescent sensor unit is held within the range that does not hinder the operation of the crescent lock lever. Any form may be used as long as the movement of the lever of the crescent lock stopped at the completion position is held at a position where it is physically blocked. Even if it does not become a form which encloses a lever, a hook-like thing should just be a form which stops rotation to the unlocking direction of a lever of a crescent lock.

Moreover, although the case where the contact switch which operates by the contact of the lever 4 of the crescent lock is employed as the lever detection unit 6 has been described, other detection is possible if the crescent lock lever stopped at the locking completion position can be detected. A method may be adopted. For example, as shown in FIG. 4, the operation of the reed switch 5 that detects the open / close state of the sash, such as the magnetic proximity sensor 7 that detects the approach of a metal lever, the pressure sensor 8 that detects the pressure when contacting, and the like. Anything may be used as long as it does not interfere with.

FIG. 5 shows another embodiment of the lever detection unit. A lever detection unit 10 that is supported while being pressed downward by a spring 11 is provided inside the crescent sensor unit main body 1, and a lever detection magnet 12 is incorporated therein. A lever detecting reed switch 9 is arranged on the main body 1 side. FIG. 5 shows a state where the lever detection magnet 12 is placed outside the detection range of the lever detection reed switch 9. When the lever detection unit 10 is moved upward relatively by the lever 4 as the main body 1 moves downward, the lever detection reed switch 9 fixed on the main body 1 side approaches the lever detection magnet 12. The contact is turned on. The lever detection reed switch 9 differs from the reed switch 5 that detects the sash open / close detection magnet 3 in the arrangement direction by 90 °. Approach can be detected reliably. By devising the strength of the magnetic force of the lever detection magnet 12, the location of the lever detection reed switch 9, the movable distance within the main body of the lever detection unit 10, etc., the length of the crescent lock lever can be flexibly handled. A lever detection unit that can be used is realized.
