Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slide cover for an electric lock (hereinafter simply referred to as a slide cover), and more particularly to a slide cover that covers the end face of a cylinder lock built in the electric lock and has excellent operability.
[0002]
[Prior art]
Like the cylinder lock, the electric lock is usually mounted near the free side edge of the outer surface of the door. For example, the electric lock operation button 1 shown in FIG. The numeric keypad (not shown) is exposed.
[0003]
Then, the personal identification number is input by operating the numeric keypad, and the handle 3 is operated and unlocked according to the unlocking signal displayed when the input personal identification number matches the pre-registered personal identification number. .
[0004]
By the way, the electric lock using the commercial power supply is locked out because the electric lock does not operate in the event of a power failure or in the case of battery consumption in the electric lock using the battery.
[0005]
Therefore, in preparation for such an emergency, the electric lock usually has a built-in cylinder lock, and the electric lock is locked and unlocked by operating the cylinder lock using the key.

This cylinder lock is usually covered with a cover plate 4, and in an emergency, the cylinder lock is slid downward in the direction opposite to the flip lid 2, in FIG. 1, downward to expose the end face of the cylinder lock with the key hole opened.
[0007]
[Problems to be solved by the invention]
The lid plate 4 is usually bent, for example, at the opening edge of the lid plate 4 having a U-shaped cross section, and the bent portion is engaged with a guide groove formed at the substrate side edge of the electric lock. Therefore, the sliding operation of the cover plate 4 which cannot be made into a narrow guide due to the size is not smooth.
[0008]
In addition, since the cover plate needs to stably cover the cylinder lock in a normal state, the guide of the slide has to be so-called awkward, and there is a disadvantage that the slide operation in an emergency becomes more difficult.
[0009]
Accordingly, an object of the present invention is to provide a slide cover that can smoothly cover a cylinder lock in a normal state and that can be smoothly slid in an emergency.
[0010]

[0011]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below based on the embodiment shown in FIGS.
In FIG. 3, reference numeral 5 denotes a substrate, and this substrate 5 is mounted in the vicinity of the free side edge of the door outer surface as in the conventional electric lock.
[0012]
A numeric keypad device 6 is mounted on the top of the substrate, and the numeric keypad device 6 is covered with a spring lid 2 in a normal state other than during the locking / unlocking operation of the electric lock, as shown in FIGS. As described above.
[0013]
The spring lid 2 is biased in the direction of rotating counterclockwise in FIG. 3 by the elasticity of the spring lid spring 7, but is normally locked by the operation button 1 to maintain the angular position shown in FIG. Yes.
[0014]
On the other hand, as shown in FIG. 3, an emergency cylinder lock 8 is mounted almost at the center of the substrate 5 with its end face with the keyhole opened outward (rightward in FIG. 3). The cylinder lock 8 is covered with a cover plate 4.
[0015]
As shown in FIG. 2 and FIGS. 5 to 7, the cover plate 4 is a frame having a concave shape in which a top surface is formed with a notch into which the operation button 1 is fitted, and side plates integrally formed on both sides.
[0016]
Then, on the inner side of the upper surface plate below the lid plate 4 (to the left in FIG. 5), a pair of connecting plates 9 having a substantially L shape as a whole are integrally formed while maintaining a substantially parallel relationship position. Projected.
[0017]
The lower part of the connecting plate 9 extends further in the door direction, and thin slide pins 11 are provided on the opposing surfaces of the extended part.
[0018]
On the other hand, a pair of guide grooves 12, 12 are formed in the vicinity of the cylinder lock 8 of the substrate 5, as shown in FIG.
[0019]
As shown in FIGS. 4 to 6, the guide groove 12 in the illustrated embodiment opens on both side plates of a guide frame made of a plate bent in a U-shaped cross section, and is a pair of symmetrically arranged. It is formed as an L-shaped notch.
[0020]
The guide groove 12 includes a first guide groove 12a (see FIG. 5) that is long and substantially parallel to the door surface, and a second guide groove 12b that is bent in the door direction at the lower end of the first guide groove 12a. It is a substantially L-shape.
[0021]
The width of the guide groove 12 is set to be slightly larger than the outer diameter of the slide pin 11, so that the slide pin 11 can slide in the guide groove 12.
[0022]
A protrusion 14 extends along at least the first guide groove 12a of the guide groove 12, and the protrusion 14 is elastically supported.
[0023]
In the illustrated embodiment, a spring frame 15 made of a thin spring plate bent in a U-shaped cross-section is screwed to the substrate 5 in a state of being overlapped with the guide frame 13 in the same manner as the guide frame 13, and the free side plates are free. The ridges 14, 14 are formed by bending the end edge so as to be a semicircular shape protruding outward in the cross section.
[0024]
As described above, the protrusion 14 is formed at the free end of the spring plate material and is elastically supported, so that it can move inward in FIGS. 4 and 6, respectively.
[0025]
As shown in FIG. 6, the distance between the extending portions of the connecting plate 9 on which the slide pins 11 are formed is set to be approximately the same as the width of the guide frame 13 (the dimension in the left-right direction in FIG. 6).
[0026]
Further, as shown in FIG. 4, in order to avoid interference with the cylinder lock 8, a part of the portion of the guide frame 13 and the spring frame 15 joined to the substrate 5 is notched in a U shape. 4 and 6, reference numeral 16 denotes a support portion for the operation button 1.
[0027]
In order to mount the cover plate 4 having the above-described structure on the substrate 5, as shown in FIG. 5, the former is pushed into the latter by aligning the slide pins 11 and 11 with the corresponding second guide grooves 12a.
[0028]
As described above, since the distance between the slide pins 11 and 11 is smaller than the width of the guide frame 13, the slide pin 11 naturally interferes with the guide frame 13.
[0029]
In the illustrated embodiment, the interference between the slide pin 11 and the guide frame 13 is positively utilized to elastically deform the connecting plate 9, and the slide pin 11 is fitted into the snap-in and the guide groove 12, as shown in FIG. In this way, the inner surface of the base portion of the connecting plate 9 is stealed to facilitate elastic deformation, and the tip of the extended portion of the connecting plate and a part of the slide pin are cut obliquely.
[0030]
Therefore, when the slide pin 11 is pushed into the guide groove 12, the pair of connecting plates 9 and 9 are expanded by the wedge action generated between the obliquely cut portion and the edge of the guide frame, and the slide pin 11 is expanded. Gets over the edge of the guide frame 13 and fits into the guide groove 12, and thereafter is stably held in the guide groove 12.
[0031]
Further, by stealing the meat of the connecting plate 9 as described above, the locking recess 16 (see FIGS. 5 and 7) extending in the vertical direction is formed inside the pair of connecting plates 9 and 9.
[0032]
Since the portion of the slide pin 11 that has been cut off obliquely is only the lower end portion of FIG. 7, after the slide pin 11 is engaged with the guide groove 12, the former does not deviate from the latter.
[0033]
Then, when the lid plate 4 is seated at the regular mounting position, as shown in FIG. 8, the protrusions 14 in the guide grooves 12 elastically contact the corresponding locking recesses 17 of the connecting plate 9, respectively. With these shape engagements, the cover plate 4 is stably attached to the electric lock.
[0034]
When it becomes necessary to lock and unlock the cylinder lock 8 such as a power failure, the lid plate 4 is pulled toward the front so as to be grasped from both sides.
[0035]
Then, due to the wedge action generated between the locking recess 17 and the protrusion 14, the elastically supported protrusion 14 is elastic in the direction in which the engagement with the locking recess 17 is released. They are deformed and their engagement is released.
[0036]
In this state, when the lid plate 4 is pulled forward, the slide pin 11 slides in the second guide groove 12b in a direction away from the door surface, and the lid plate 4 floats from the substrate 5 as shown in FIG.
[0037]
Next, when the cover plate 4 is moved upward, the slide pin 11 slides upward in the first guide groove 12a, and the end face of the cylinder lock is exposed as shown in FIG.
[0038]
In addition, when the slide pin 11 exists in the 1st guide groove 12a, although the cover plate 4 can be rotated around the slide pin 11, it does not interfere with the raise of the cover plate 4.
[0039]
Further, when the slide pin 11 slides in the first guide groove 12a, the protrusion 14 comes into elastic contact with the slide pin 11, and a frictional resistance is generated therebetween. 4 will never fall.
[0040]
If the cover plate 4 is moved in the direction opposite to that described above after the cylinder lock 8 is operated, the cover plate 4 smoothly moves to the proper mounting position and is seated as shown in FIG.
[0041]
In the illustrated embodiment, the pair of protrusions 14 and 14 are arranged so as to be elastically deformable on the inside, and the slide pins 11 and 11 are engaged with the slide pins 11 and 11 from the outside. The same effect can be obtained even if engaged with the ridge.
[0042]
Further, in the illustrated embodiment, the guide groove 12 and the protrusion 14 are provided on the substrate 5 side, and the slide pin 11 and the locking recess 17 are provided on the lid plate 4 side. However, the same effect can be obtained.
[0043]
【The invention's effect】
As is apparent from the above description, the present invention provides guidance for relative movement between the lid plate and the substrate by sliding the slide pin and the guide groove with the former being separated from the latter. The movement is very smooth.
[0044]
Further, since the lid plate is locked by the engagement of the protrusion and the locking recess when the lid plate is in the regular mounting position, the normal mounting of the lid plate can be stabilized. Various effects are obtained.
