Description

[Detailed description of the invention] <Industrial application field> Regarding room vendors that are installed in guest rooms of hotels etc. and lock and unlock storage doors by remote control,
In particular, the present invention relates to a locking device for a room bender having double-opening doors.

<Conventional technology> Generally, it is installed in each guest room of a hotel, etc., and is used to store food,
There is a room vendor that displays products such as luxury items and daily necessities, and allows customers to take out the products in a self-service manner as needed.

Such a room vender is configured such that the locking device of the storage door is locked or unlocked by a remote control signal from outside the guest room, such as a hotel reception desk, when the product is taken out. Such room vendors were often formed into a box with a substantially L-shaped cross section in order to increase the variety of display products and storage capacity, and to improve the appearance.

Therefore, at least two external double doors were provided, one at the top of the roughly L-shaped box that faced the front and opened upwards, and the other at the bottom of the box that faced top and opened toward the front. . A locking device is provided for each door, and the stored products can be taken out by locking and unlocking each door.

<Problems to be solved by the invention> However, in the conventional locking device for room vendors, each door is equipped with a locking device, which increases the number of locking devices, making it more complicated, and increasing the cost. I had a problem with getting high.

<Means for solving the problem> This invention was made to solve the above problem. at least two doors forming an external double door with a first door and a second door provided on the upper surface of the lower part of the box body; The locking fitting has a locking groove that is opened at the top and a sloped part that is tapered from the base end toward the locking groove, and the locking fitting is driven by a solenoid provided in the box body to lock and unlock the locking position. and a locking lever that moves between the locking position and the locking position and abuts the sloped part of the locking metal fitting in the locking position to advance the locking metal fitting by the length of the sloped part and engages in the locking groove, The room bender is configured such that when the locking lever engages the locking groove, the lower edge of the first door rests on the free edge of the second door to prevent rotation of the second door. It is a locking device.

<Operation> This invention is constructed as described above, and when the first door and the second door are closed, when the solenoid is driven to the locking side by the locking operation signal, First, the locking lever rotates and comes into contact with the inclined part of the locking fitting provided on the first door.

Further, as the locking lever rotates, the locking lever and the inclined portion slide, and the locking lever reaches the locking groove and becomes locked.

At this time, the lock fitting moves forward by the length of the inclined portion to rotate the first door, causing the lower edge of the first door to extend over the free edge of the second door.

The overhang of the first door prevents the second door from rotating, thereby maintaining the locked state of the first door and the second door.

On the other hand, when the solenoid is driven to the unlocking side by the unlocking operation signal, the engagement between the locking lever and the locking metal fitting is released, and the first door is moved back by the above-mentioned overhang. Then, the first door and the second door are each in a state where they can be opened.

<Example> Hereinafter, an example of this invention will be shown in Figures 1 to 4.
This will be explained based on the diagram.

As shown in the figure, the room bender locking device is composed of a first door 5, a second door 10, a locking fitting 15, a locking lever 20, and a solenoid 25 provided on the room bender main body 1. .

In the embodiment, the room bender main body 1 is made of colored synthetic resin, etc., and is formed into a box with a substantially L-shaped cross section. A second storage chamber 4 whose top surface is open is provided.

The first door 5 is made of, for example, transparent synthetic resin, and a handle member 7 having a U-shaped cross section and forming a handle is fixed to its lower free edge.
Further, the upper end edge of the first door 5 is pivotally connected to the upper corner of the room bender main body 1 by a shaft 8, and is arranged to cover the opening of the first storage chamber 3 so as to be openable and closable.

The second door 10 is made of, for example, transparent synthetic resin, and a handle member 12 having a U-shaped cross section and forming a handle is fixed to its free edge. Also, the second
The other edge of the door 10 is pivotally connected to the front corner of the room bender main body 1 by a shaft 13, and is arranged to freely open and close the second storage chamber 4.

The first door 5 and the second door 10 are double-opening doors, and the trajectories of the handle members 7 and 12 provided at the free edges of the respective doors are formed to intersect. When opening and closing the doors, one door is first opened and closed with one door closed, and then the other door is opened and closed.

Moreover, on the inside of the first door 5, a handle member 7
A lock fitting 15 is provided upright on top. The lock fitting 15 has a sloped part 16 formed on its lower edge, and the sloped part 16 is arranged so that it comes into contact with the sloped part 16 when the first door 5 is closed and the locking lever rotates. (shown by the solid line in FIG. 3). The inclined portion 16 is formed so as to become tapered from the base end to the distal end of the lock fitting 15, and at the tapered end of the inclined portion 16, a lock groove 17 is further cut upward and opened downward. It is formed. Then, with the first door 5 closed, the inclined portion 16 of the lock fitting 15 and the lock groove 17
is formed to protrude inward from a notch groove 2a provided in the frame 2 of the room bender main body 1.

The locking lever 20 has a locking metal fitting 15 at one end.
It has a lock portion 21 formed on a curved inclined side that abuts and engages with the solenoid, and an engaging portion 22 that engages with the engaging piece 27 of the solenoid 25 is formed at the other end.
When the first door 5 is closed, the locking lever 20 is connected to the inclined portion 16 of the locking fitting 15.
It is pivotally mounted at a predetermined position of the frame 2 of the room bender main body 1 by a shaft 23 so as to abut and engage with the lock groove 17.

In the embodiment, the solenoid 25 is a latching type solenoid, which is fixed to the frame 2, and is formed so that its plunger 26 operates to a forward end or a backward end based on an operation signal, and maintains the respective operating end position. ing. In addition, the plunger 26
An engaging piece 27 is fixed to the lock lever 20, and the engaging piece 27 is engaged with the engaging portion 22 of the locking lever 20. As the solenoid 25 operates, the lock lever 20 is driven to move the lock portion 21 into the locked position (indicated by the two-dot chain line in FIG. 4) and the unlocked position (indicated by the solid line in FIG. 4). It is configured to move between.

Further, the solenoid 25 is connected to a control circuit (not shown), and is configured to be activated by an operation signal from a remote control panel located at a remote location.

Note that this invention is not limited to the configuration of the above-mentioned embodiments; for example, several sets of external double doors formed by the first and second doors may be arranged in parallel,
At that time, the locking metal fittings and locking levers provided for each set of doors may be individually controlled by solenoids, or may be a locking lever connected to a single solenoid by a connecting rod or the like. Locking and unlocking may be controlled by

Furthermore, even in the case of a double door that combines one first door with a plurality of second doors, by equipping one first door with a locking device, a plurality of second doors can be opened. can prevent the door from rotating.

<Effect of the invention> Since the locking device of the room bender of this invention has the above-mentioned configuration, by locking the first door, the rotation of the second door is prevented and the first and second locked states are maintained. can be maintained, the locking device can be constructed simply, the number of parts can be reduced, and the construction can be made at low cost.
