Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to an electric lock for a sliding door, and more specifically, an electric operating part is provided on the door frame side, a manual operating part is provided on the sliding door frame, and the electric operating part is provided with an electric operating part on the door frame side. Or it relates to something that can be locked or unlocked as desired by any manual operation part.

(Prior art) Conventionally, in this type of electric lock, the manual operation part and the electric operation part are provided in the same case, so when the sliding door side is used, the solenoid is energized and the movable The wiring had to be wired to the sliding door side, which is the main part, which was difficult, and wire breakage was likely to occur, resulting in a lack of reliability. In addition, if it is installed on the door frame side, which is the fixed part, wiring is easy and there will be no disconnection, but the manual operation part is also moved to the door frame side, and in this case, the space is small, making installation work inconvenient and difficult to operate. became. Moreover, there are many inconveniences such as manual locking and unlocking operations and sliding door opening/closing operations that must be performed separately.

(Object of the Invention) The present invention is intended to eliminate the above-mentioned conventional drawbacks, and the specific configuration of the present invention will be explained below based on the illustrated embodiments.

(Structure and function) (1) is a case that is attached to the door frame of a sliding door, and the front plate (
2) is fixed. (3) and (4) are operating rods that are fitted into the case so that they can be moved up and down, and locking rods (6) and (6) are fixed to each operating rod. An operating part (5) that is linked to the operation of a manual operating part (not shown) consisting of a cylinder, thumb turn, etc. is engaged with the four holes (3a) of one of the operating rods (3). The actuating part (5) is moved up and down by the operation of the part, and the operating part (3) is moved up and down.

(3b) is a connecting part formed on the operating rod (3), and when the door is closed, it is fitted with the electrically operated operating lever (φ) described later.

(7) is a case that is attached to the door frame at a position opposite to the front plate 2 of the case 1, and a solenoid αQ is installed in the case.
is provided. Each time the solenoid is energized, the plunger (10a) engages with a certain amount of resistance.

(8) is a pinion that is pivotally supported approximately in the center of the case (1), and a rack part (3c) provided on the operating rods (3) and (4).
) and (4c) are engaged, and when the operating lever (3) moves up and down, one of the operating levers (4) also moves up and down in conjunction with the same pinion. Figure 1 shows the door in the closed state. And in the unlocked state, that is, the locking lever (6)
, (6) have retreated into the case (1), and the tips of the locking rods have entered the receiving holes (71) and (81) provided in the upper frame (70) and floor (80). In this state, if you pull the sliding door in the opening direction, the sliding door will open.

Next, when locking with a manual operation part such as a cylinder or thumb turn, operate the manual operation part and operate the operation part (5
) is moved downward, the operating rod (3) is slid downward. Then, the locking rod (6) integrally connected to the operating rod (80) slides downward, and its lower end protrudes from the sliding door and engages in a receiving hole (81) provided in the floor.

At this time, the pinion (8) that meshes with the rack part (3C) of the operating rod (3) rotates clockwise, and the other operating rod (4) rotates clockwise through the rack part (4a) that meshes with the same pinion. )
the other locking rod (6) is projected from the sliding door and inserted into the receiving hole (71) provided in the upper frame (70). That is, the locked state shown in FIG. 2 is obtained. To unlock it, just do the opposite operation.

Also, in the unlocked state shown in FIG.
To lock the lock using O, when the solenoid is energized and the plunger (10a) is made to protrude from the solenoid, that is, to slide downward, the actuating part (10b) integrated with the plunger slides downward, and the actuating part (10b) slides downward. The locked state can be obtained in the same manner as described above by sliding the operating lever (3) that engages with the lever downward.

To unlock electrically, simply energize the solenoid and retract the plunger.

In this way, when the door is closed, the door can be locked or unlocked as desired by either a manual operation part such as a thumb turn or a cylinder, or an electric operation part such as a solenoid.

(Modifications, etc.) In the example, a bistable latching solenoid was shown as the electric operation part, but since the plunger is held in the protruding and retracted states with a certain resistance force, this holding force can be used. The purpose is to maintain the rising and falling states of the locking member, and if the locking lever is equipped with a mechanism that maintains this rising and falling state with a certain amount of resistance, even a normal solenoid can be used. This purpose can be achieved by using two solenoids, one for raising and one for lowering, and the type of solenoids does not matter.

In addition, a reversible rotary motor is used instead of a solenoid,
It is also possible to perform the locking and unlocking operations by changing the rotational movement of the motor to the linear movement of the locking member using a mechanism such as a rack or pinion.

In addition, in the embodiment, two locking rods are provided so as to be vertically retractable, but only - two locking rods may be provided, and in that case, a rack and a pinion are not required.

Further, although a rack and a pinion are used as means for interlocking the two locking rods, it is of course possible to simply use a cam instead of the pinion.

Furthermore, in addition to the illustrated embodiment, the locking/unlocking method using a manual operating part such as a cylinder or thumb turn may be achieved by, for example, providing the cylinder or thumb turn coaxially with the pinion (8), and directly controlling the pinion (8) with the cylinder or thumb turn. It may be provided so that it can be locked and unlocked by rotating it.

As described above, according to the electric lock for sliding doors according to the present invention,
An electric operation unit consisting of a solenoid, motor, etc. for locking and unlocking the locking member provided on the sliding door side is placed on the door frame side, and a manual operation unit consisting of a cylinder, thumb turn, etc. for locking and unlocking the same locking member. When the door is closed, the actuating part of the electric operating part engages with the operating rod operated by the manual operating part, and from the sliding door side, the operating part of the electric operating part engages with the operating rod operated by the manual operating part.
From the door frame side, each door can be locked and unlocked independently using the electric operation section, and the electric operation section can be attached to the door frame side, which is the fixed part, and the wiring work is simple and easy to use. There is also no risk of wire breakage or other malfunctions in the electrical system. In addition, the manual operation part consisting of a cylinder, thumb turn, etc. can be installed on the sliding door side like a normal sliding door lock, so it is not only easy to install, but also locks, unlocks, and opens/closes the door. It can produce excellent effects such as being able to perform these steps in succession.
