【Example】

Figure 1 shows a secret machine equipped with a secret electric lock operating device 1 according to the present invention. This is an example of the configuration of an electric lock operating system. In FIG. 1, a seal is attached to a gatepost of an entrance (not shown) to which an electric lock 100 is attached. A Cret electric lock operator (hereinafter referred to as the operator) 1 is installed, and a password code is When setting device 300 is installed and signal lines L100 and L101 are connected between them, Also, a power transformer 400 that steps down the alternating current is connected to the password setting device 300. The configuration is as follows.

[0007] In such a system, the password setting switch (rotary -Switch) The 4-digit PIN code preset on 300a is sent via signal line L101. is transmitted to the electric lock 100 side, and the password is entered by operating the numeric keypad 1a of the operating device 1. When you enter the password, the input password will be combined with the password set on the setting device 300. When the unlock operation key 1b is operated after comparing and determining a match, a message is sent from the operation device 1. An unlock command signal is transmitted to the setting device 300 side via line L100, and the setting device 300 Then, upon receiving the unlock command signal, send an unlock signal to the electric lock 100 via the signal line L101. It is designed to be output and unlocked. Note that 1c is a lock operation key. In addition, the lock status signal output from the electric lock 100 is sent to the setting device via the signal line L100. The signal is transmitted to the 300 side and drives the lock indicator 300c or the unlock indicator light 300d. It is designed to be displayed.

[0008] The controller 1, which forms part of such a system, is installed at a door such as at the entrance as described above. Externally, it is integrally constructed with a frame-shaped case 2 and a protective door 3 located at the front of the case 2. The case 2 and the front protective door 3 prevent the controller 1 from being directly exposed to wind, rain, dust, etc. The protective door 3 is configured to open horizontally, as shown in Figure 2. The controller 1 is placed in a position where any adult or child can operate the keys in a comfortable posture. It is possible to set

[0009] Next, the configuration of the operating device 1, which is the main part of the present invention, will be explained. 3 to 6, a mounting panel is provided on the outer periphery of the operating device 1 slightly behind the front end. 1d, an opening 2a is formed on the rear surface of the frame 2. Inside the opening 2a, there is a The front end of the device 1 is supported in a state that protrudes forward, and the support is provided by the mounting of the operating device 1. The attached panel 1d and the rear surface 2b of the frame 2 are attached using screws (not shown) or the like. Therefore, it is possible. The protective door 3 located on the front side of the frame body 2 is moved in the ``lateral direction'' using the support shafts 4, 4 as fulcrums. It can be opened and closed, and a torsion coil is used to open and close the protective door 3 and prevent the support shafts 4, 4 from coming off. This is done using coil springs 5, 5 which function as both a spring and a compression coil spring. It is structured as follows.

0010 In other words, the upper and lower positions of the rear surface of one side of the protective door 3 are fixed vertically. Two tube bodies 3a and 3b are each configured with a spacing of A coil spring 5 is sandwiched between the tube bodies 3a and 3b. , in the tube bodies 3a and 3b located at the top, from above, the tube body 3b located at the bottom , 3a, a support shaft 4 is inserted from below. Top surface 2 of frame 2 c and one end of the lower surface 2c, each has a small diameter blind hole with the same axis in the vertical direction. 2e, 2e are constructed, and the ends of the support shafts 4, 4 are inserted into these blind holes 2e, 2e. The support shaft is supported by coil springs 5, 5 which have compression and repulsion action. 4, 4 ends, that is, the protective door 3 is configured so as not to come off from the frame 2.

[0011] Next, the structure of each part supporting the protection door 3 will be described in detail with reference to FIGS. 3 and 7. support The holding shaft 4 is formed into a stepped shaft consisting of a small diameter part 4a and a large diameter part 4b, and is attached to the upper end of the door 3. and the inner diameter of the tubes 3a, 3a located at the lower end, and the diameter of the blind holes 2e, 2e on the frame 2 side. is configured to have a large diameter in accordance with the large diameter portion 4b of the support shaft 4. Also, the protective door 3 side The diameters of the other tubular bodies 3b, 3b and the winding diameter of the coil spring 5 are set at the small diameter portion 4a of the support shaft 4. Together, they are configured to have a small diameter. In addition, the height of each component is The height (length) of the large diameter portion 4a of the support shaft 4 is h1 The height (length) of the small diameter portion 4a of the support shaft 4 is h2 The depth of blind hole 2e is h3 The height of the tube body 3a is h4 Tube 3b The height of tube 3b is h5 The distance between the tube body 3a and the tube body 3b is h6. The height (thickness) of the coil spring 5 is h7 If the height (thickness) of the coil spring 5 when compressed is h8, Almost the same as (h1) = (h3) + (h4), (h2)>(h5)+(h6) (h7)<(h6)>(h8) (h3)<(h6)-(h8), and the protective door 3 can be easily and reliably pivoted. It is structured so that it can be done. Therefore, in order to attach the protective door 3 to the frame 2, first attach the small diameter part 4a of the support shaft 4. When inserted from the large-diameter tube 3a toward the small-diameter tube 3b, the tube 3a The diameter of the coil spring 5 located between and the tube body 3b is smaller than the large diameter portion 4b of the support shaft 4. Therefore, while compressing the coil spring 5 by the stepped surface of the support shaft 4, the frame body 2 can be inserted up to the end face of the tube body 3a.

0012 With the support shaft 4 pressed in this way, move the end of the protective door 3 to open the frame 2. When moved in the direction of the hole 2e, the end of the support shaft 4 is pushed by the repulsive force of the coil spring 5. It is turned back and enters the blind hole 2e, so that the protective door 3 can be easily framed without coming off. It is pivotally supported by body 2. Note that both ends 5a, 5 of the coil spring 5 also function as a torsion coil spring. b protrudes long in the direction necessary to open the protective door 3, and one end 5a is a protective door. The other end 5b contacts the inner surface of the protection door 3, and the other end 5b contacts the rear surface 2b or side surface 2d inside the frame 2. The torsion spring force necessary to open the protective door 3 is always exerted. In addition, when the protective door 3 is opened in the "lateral direction", the protective door 3 will come into contact with the side surface 2c of the frame. It is designed so that it can be locked at a certain position.

[0013] Also, when the controller 1 is not operated, the protective door 3 must be closed. For this purpose, as shown in FIGS. 8 and 9, there is a central attachment on the inner surface of the end opposite to the pivot side of the protective door 3. A protrusion 3e protruding inwardly, and a clamping part 6 provided within the frame 2. This is possible by using a so-called push-catch configuration. P For the catch, when the protrusion 3e side is lightly pressed against the gripping part 6 side, the gripping part 6 will be released. When the protrusion 3e is held and pressed again, it will move along the slope of the front end of the protrusion 3e. The clamping part 6 opens and the clamped protrusion 3e is released and protected by the spring force. This allows the door 3 to be opened.

[0014] In addition, the opening and closing direction of the protective door 3 is ``horizontal'' and the two forces of torsional force and compressive force are The coil springs 5, 5 have a structure in which the door 3 is opened and prevented from coming off. The present invention is applicable not only to the above-mentioned secret electric lock operating device, but also to other devices such as It can also be used for products with conventional covers that open in the upward direction, such as drip-proof outlets. becomes possible.

[0015]

[Effect of the idea]

As understood from the above explanation, the secret electric lock operating device of the present invention is Equipped with a side-opening protective door at the front, it can provide the following effects. In other words, the protective door does not open ``upward'' like in the past, but opens ``sideways''. Because the protective door is configured so that it is visible when entering keys on the operating device, and does not interfere with operation. For this reason, it is set at a height that is easy for both adults and children to handle. A secret electric lock operating device can be installed at the location. In addition, the screws are used to open the protective door and to prevent the support shaft supporting the protective door from coming off. A single coil spring performs the two functions of a compression coil spring and a compression coil spring. Because of this, it is possible to reduce the number of component parts and the space required for them. It can be made smaller.
