[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a door locking / unlocking display device capable of visually identifying the locked / unlocked state of a guest room such as a hotel from the outside.

[0002]

[Prior art]

 The door locking / unlocking display device is equipped with a display that displays the door locking / unlocking state by protruding it from the surface of the outdoor seat of the door by operating the thumb turn. It is well known in the past to inform employees of the presence or absence of customers.

When the customer locks the door by operating the thumb turn, the display body is projected from the surface of the outdoor side seat plate, so that the employee on the aisle side can see it and stay in the room. Knowing that there are people, for example, refrain from cleaning the cabin.

Usually, this display body is made as an integral body, and the whole body has a noticeable red color or the like, unlike a seat plate of a black color or a plating color of nickel or the like.

[0005] However, originally, it is necessary for only the employee to know about the protrusion of the display body, that is, the presence or absence of the customer, so it is necessary to be known to another customer of the third party. There is no such thing.

In the conventional display body, the protruding state becomes too conspicuous to the customers who dislike interference, and in the stored state, the front face of the display body becomes conspicuous because the front surface of the display body is distinguished from the surface of the seat plate having a different color, which makes it attractive. However, there are problems such as poor appearance and lack of smart appearance.

[0007]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The door locking / unlocking display device of the present invention prevents the display body from being unnoticeably unnecessarily in the projected state, and is hard to distinguish from the seat plate in the stored state. It was proposed for the purpose of doing.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a door locking / unlocking display device including a display body that is pushed in from the surface of the outdoor side seat plate of the door by the operation of the thumb turn to display the locked / unlocked state of the door. The exposed part of the display is composed of the front plate and the display color that forms the body part.The surface of the front plate has the same color system as the surface of the seat plate, and the surface of the display color has a different color from the surface of the seat plate. Characterize.

[0009]

[Action]

 According to the door locking / unlocking display device of the present invention, the surface of the front plate of the display body has the same color as the surface of the seat plate, so that the display body shown in FIG. In the unlocked state, it is difficult to distinguish the front plate surface and the seat plate surface of the display from each other, so that the design does not give a sense of discomfort and the appearance of smart appearance is not impaired.

Further, in the protruding state of the display body shown in FIG. 2, that is, in the locked state of the door by the thumb turn, the display color forming the body part of the display body indicates the presence of the customer with a color different from the surface of the seat board. This means that the employee will obtain the necessary and sufficient signal by looking at it diagonally from above or from the side.

Normally, the presence of the front plate of the display member, which is of the same color as the surface of the seat plate, makes it difficult for other customers who walk in the center of the passage to recognize the protruding state of the display member. As a result, the customer in the guest room will be kept in a non-interfering state.

[0012]

【Example】

 The present invention will be described below with reference to the embodiments shown in FIGS. Each member of this invention is usually made of a metal material such as stainless steel or brass, or a hard synthetic resin material.

In FIGS. 1 and 2, reference numeral 1 is a door of a guest room such as a hotel, 2 is a seat plate of a lock device (not shown) fixed outside the door 1, and 21 is a cylinder forming a part of the lock device. A mounting hole provided on the seat plate 2 for mounting a lock (not shown), and 22 denotes a mounting portion provided on the seat plate 2 which is shared with the locking device for mounting the frame 3 of the locking / unlocking display device. .

The frame 3 in the illustrated example is formed in a box shape, and is fixed to the seat plate 2 by screwing a flange portion (not shown) extending in a direction perpendicular to the plane of the drawing.

A cylindrical cam 5 having, for example, a V-shaped groove 51 is fixed with a pin 9 to the rotary shaft 4 rotatably supported by the seat plate 2 and the bottom plate 31 of the frame body 3. A front end of the rotary shaft 4 is supported by the circular groove of the seat plate 2, and a central portion of the rotary shaft 4 is supported by the bottom plate 31 of the frame body 3 via the small diameter portion of the cam 5.

A rear end portion 41 forming an angular axis of the rotary shaft 4 is projected to the rear of the frame body 3 and is linked to a rotary shaft (not shown) of the thumb turn through an appropriate linking member 10. Therefore, the cam 5 can be turned to the right or left by the turning operation of the thumb turn.

The display body 6 that protrudes and is inserted through the projection insertion hole 23 provided in the outdoor side seating plate 2 to indicate the locked / unlocked state of the door, that is, the presence or absence of the customer is a columnar shape such as a columnar shape. And a follower piece 7 fixedly provided integrally or separately at the rear part thereof.

The driven piece 7 that is held in the frame body 3 together with the display body 6 is formed in, for example, a rectangular parallelepiped shape, and extends in the front-rear direction (left-right direction in the drawing) along a guide piece 32 that is integrally provided in the frame body 3. It is slidable, and is engaged with the cam 5 by a protruding piece 71 having a V-shaped cross section which is integrally provided on the driven piece 7.

The display body 6 of the illustrated example includes a tubular display collar 62 fitted in a columnar portion 61 integrated with the driven piece 7, and a front plate 63 that covers the tip end surfaces of the columnar portion 61 and the display collar 62. Each member 61, 62, 63 is fixed to each other by screwing a screw 64 integrally provided on the rear surface of the front plate 63 into a screw hole of the columnar portion 61.

What is important here is that the surface of the front plate 63 has the same color system as the surface of the seat plate 2. That is, if the surface of the seat plate 2 is a glossy black color such as black, brown or nickel, the surface color of the front plate 63 should be matched with each other. It is more preferable that the front plate 63 and the seat plate 2 have the same material and surface treatment method in addition to color.

The surface of the display collar 62 forming the body of the display body 6 is a color that is clearly different from the surface color of the seat plate 2, for example, red or orange. The surface color of the display color 62 may be painted, baked, or the like, but the entire display color may be formed of a synthetic resin material having a color different from the surface of the seat plate 2 or any other material.

When the display color is entirely made of a material having a color different from the surface color of the seat plate 2, even if the display collar 62 is worn by the protruding and inserting action of the display body 6 with respect to the seat plate 2, the surface thereof is always the same color. Therefore, there is no need for replacement, which is advantageous.

Reference numeral 8 is a compression spring provided around the display collar 62 of the display body 6, both ends of which are brought into contact with the inner surface of the seat plate 2 and the front side of the driven piece 7, respectively. Along with this, the display body 6 is urged in the direction in which the display body 6 is pulled in (the storage direction).

As shown in FIG. 1, when the protruding piece 71 of the driven piece 7 is fitted in the V-shaped groove 51 of the cam 5, the display body 6 is housed from the surface of the seat plate 2 on the outdoor side. In the state, it shows that there is no customer, but when the turning operation of the thumb turn rotates the rotating shaft 4 by 90 ° and the lock mechanism (not shown) is operated to lock the passenger from the cabin side, Meanwhile, the protruding piece 71 of the driven piece 7 is displaced rightward in FIG. 1 along the slope of the V-shaped groove 51 of the cam 5 against the biasing force of the compression spring 8, as shown in FIG. Thus, the inner end portion 52 (right end portion) of the cam 5 is pushed up.

Here, the display body 6 projects from the surface of the seat plate 2, and the employee of the hotel or the like knows the presence of the customer. When the thumb turn is turned in the opposite direction, the driven piece 7 is urged by the compression spring 8 with the rotation of the cam 5 and retracts to the state of FIG. 1, and the display body 6 also returns to the retracted position.

[0026]

[Effect of device]

 According to the door locking / unlocking display device of the present invention described above, when the display body is housed, the front exposed portion of the display body is difficult to distinguish from the surface of the seat plate, and the seat plate portion has a strange feeling. It has the effect of not giving away the aesthetics.

Further, in the protruding state of the display body, since the color distinction is recognized only by the display color of the body portion, other third parties can recognize the protruding state of the display body. It will be difficult to do so, and only the employees of the hotel will be given necessary signals and sufficient signals.
