  However, the existing locking / unlocking display devices including Patent Document 1 are integrally incorporated from the beginning with the locking device attached to the door, and are not retrofitted. Further, since the display device is provided inside the locking device, the number of man-hours and the number of parts are increased, and the cost is increased accordingly.

  Therefore, an object of the present invention is to provide a locking / unlocking display device that can be easily attached to an existing locking device at a very low cost.

  In order to solve the above problems, a locking / unlocking display device according to one aspect of the present invention includes a pedestal fixed to a door, and a thumb turn that rotates with respect to the pedestal and switches between a locking state and an unlocking state. A locking / unlocking display device that is installed on a door locking device and displays whether the door locking device is in a locked state or in an unlocked state. The color-specific display board divided into the two areas and a shielding member that is used by being attached to the thumb turn and rotates together with the thumb turn. The shielding member partially covers the surface of the color display board. In the unlocked state of the door locking device, the shielding plate covers one region of the color-specific display plate and hides the other region, and the door is exposed. The locking device is locked , It said shielding plate, characterized in that exposing the one region with invisible over the other region of the Color panel.

  In a preferred embodiment, the color display plate is formed in an arc shape, the color display plate is divided into two in the circumferential direction, and the two regions are partitioned. The plate is similar to the arc-shaped region divided into two.

  According to the locking / unlocking display apparatus according to the present invention, the locking / unlocking display function can be easily and inexpensively added simply by being attached to an existing locking apparatus provided on the door.

FIG. 1 is a front view showing color-specific display plates constituting a locking / unlocking display apparatus according to an embodiment of the present invention. FIG. 2 is a front view showing a shielding member constituting the locking / unlocking display apparatus according to the embodiment of the present invention. FIG. 3 is a perspective view for explaining an installation method of the locking / unlocking display apparatus according to the embodiment of the present invention. FIG. 4 is a front view illustrating a state in which the door locking device is displayed in an unlocked state by the locking / unlocking display device according to the embodiment of the present invention. FIG. 5 is a side view showing a state where the locking / unlocking display device according to the embodiment of the present invention is attached to the door locking device. FIG. 6 is a front view for explaining a state in which the door locking device is displayed in the locked state by the locking / unlocking display device according to the embodiment of the present invention.

  Hereinafter, specific examples of the locking / unlocking display device of the present invention will be described with reference to the drawings. This locking / unlocking display device is installed in a door locking device using a thumb turn provided on a general indoor door or entrance door, etc., and the locking state and unlocking state of this door locking device are clarified. It makes it possible to distinguish.

  This locking / unlocking display device comprises a color-specific display board 11 as shown in FIG. 1 and a shielding member 22 as shown in FIG. The color-specific display board 11 is a paper member having an adhesive applied on the back surface, and has an arch shape as a whole. In addition, two target areas 11r and 11b are set in the arc direction, and the area 11r is red and the area 11b is blue.

  On the other hand, the shielding member 22 includes an arc-shaped shielding plate 23 and a substantially rectangular standing portion 24. The standing portion 24 is integrally connected to the shielding plate 23 and extends from the end portion of the shielding plate 23 at a right angle. The shape of the shielding plate 23 is similar to each of the regions 11r and 11b of the color-specific display plate 11, and has a slightly large area so as to completely shield each of the regions 11r and 11b.

  An adhesive is applied to the outer surface of the standing portion 24 (the right rear surface in FIG. 2). The shielding member 22 is preferably made of resin and ensures a certain durability, but may be made of paper whose strength is secured by surface treatment. Moreover, although it is effective to make the shielding member 22 inconspicuous color such as gray, since the metal surface is usually exposed in the door locking device, the surface treatment is performed so as to give a metallic luster. You may make it have the external appearance similar to a metal surface.

  Next, with reference to FIG. 3 thru | or FIG. 6, the usage of this locking / unlocking display apparatus is demonstrated. First, the color-specific display plate 11 is inserted between the thumb turn 34 and the pedestal 35 of the door locking device 33 and is attached to the upper half of the pedestal 35 as shown in FIG. Next, as shown in FIG. 4, the standing portion 24 is attached to the left side surface of the thumb turn 34 so that the shielding plate 23 completely hides and shields the region 11 r of the color-specific display plate 11. FIG. 5: is the side view which looked at the locking device for doors to which the locking / unlocking display apparatus of a present Example was attached from the side.

  In this state, as shown in FIG. 4, only the blue region 11b of the color-specific display board 11 is visible. In the locking / unlocking display device of the present embodiment, blue represents the unlocking state. Here, it is assumed that the thumb turn 34 is turned to the right to bring the door locking device into the locked state. In that case, as shown in FIG. 6, the blue region 11b of the color-specific display board 11 is hidden, and only the red region 114 is visible. Here, red represents a locked state.

  Therefore, when the red arc is visible on the door locking device, the door is locked, and when the blue arc is visible, the door is unlocked, so that it can be seen at a glance whether the key is closed. Moreover, it is possible to install the locking / unlocking display device at an extremely simple and low cost, in which only two members of the color-specific display plate 11 and the shielding member 22 are attached to the existing door locking device.

  As described above, the present invention has been described based on the embodiment, but the present invention is not limited to this, and may be modified without departing from the spirit of the present invention, and each feature may be appropriately combined. Also good.

  By using the locking / unlocking display device according to the present invention, the locking / unlocking display function can be easily and inexpensively added simply by sticking to an existing locking device provided on the door.
