Description

[0001]
BACKGROUND OF THE INVENTION
The present invention energizes the lead wire on the electric lock side provided on the sliding door and the lead wire on the control panel (operation panel) side provided on the door frame side in order to send low voltage power to the electric lock. The present invention relates to a current-carrying metal fitting for sliding doors. This sliding door energization metal fitting relates to a sliding door energization metal fitting that is energized when the sliding door is closed, and is in a non-energized state when the sliding door is opened.
[0002]
[Prior art]
Conventionally, an example of the electrical fitting for sliding doors closest to the present invention is described in Japanese Utility Model Publication No. 3-12128. The embodiment described in this publication is basically a shamisen drum-shaped movable contact plate that is attached to the upper arm of a sliding door via a pivot box and connected to an electric lock via a sliding door side lead wire. On the other hand, an L-shaped fixed contact is provided on the upper frame of the door frame via an insulating mounting bracket so as to face the claw-shaped protrusion of the movable contact plate, and is connected to the lead wire on the control panel side. It consists of a board.
[0003]
Thus, the movable contact plate is urged by the spring force of the spring member built in the pivot box so that the claw-like projecting portion always projects from the upper window of the pivot box, and when the sliding door is closed, The movable contact plate on the sliding door side is brought into an energized state by sliding contact with the fixed contact plate on the door frame side.
[0004]
However, the above configuration has the following drawbacks.
(1) The mounting location of the movable contact plate and the fixed contact plate is limited. That is, since the movable contact plate slides in contact with the fixed contact plate in the horizontal direction, these contact members are the upper door of the sliding door in consideration of functionality, safety, ease of connection, etc. It must be installed at a specific location on the top frame of the door frame facing the front side. Therefore, for example, when the connecting end portion of the lead wire on the control panel side is guided “inside the top of the vertical frame” of the door frame via the conduit, it is not suitable for use.
(2) It is not easy to mount the movable contact plate and the fixed contact plate. That is, what is the clearance (clearance) between the upper end surface of the upper lid of the sliding door and the inner wall surface of the upper frame of the door frame facing this, and the claw-like shape of the movable contact plate when the sliding door is opened and closed In order to prevent the protruding part from sliding on the inner wall surface of the upper frame of the door frame, considering the circumstances such as the amount of protrusion of the claw-like protruding part protruding from the upper window of the pivot box, In addition, it is required to attach both contact plates with high accuracy so that the contact failure between the movable contact plate and the fixed contact plate does not occur. Therefore, the movable contact plate and the fixed contact plate cannot be attached in a so-called “about feeling”. Therefore, workers need a certain level of skill.
(3) The claw-like projecting portion of the movable contact plate gets in the way and the sliding door cannot be easily removed. That is, the movable contact plate is urged so that its claw-like protruding portion always protrudes from the upper window of the pivot box by the spring force of the spring member built in the pivot box. The sliding door cannot be easily removed from the door frame during repair or repair.
[0005]
[Problems to be solved by the invention]
In view of the conventional problems as described above, the first object of the present invention is not only to place the current-carrying metal fittings in the upper frame of the sliding door and the upper frame of the door frame, but also in the “vertical frame upper part” of the door frame and “ It can be attached to the downpipe. The second purpose is that the electric bracket can be attached in a so-called “about feeling” even if the worker does not require a certain level of skill. The third purpose is that the sliding door can be easily removed from the door frame at the time of inspection and repair of the current-carrying metal fittings. The fourth purpose is to increase the magnetic field at the time of closing the sliding door as much as possible, or to increase the contact area between the fixed electrode and the movable electrode, so that the sliding door is closed or the clearance between the sliding door and the door frame, etc. It is to prevent contact failure between the fixed electrode and the movable electrode depending on circumstances. The fifth object is to expect advantages such as easy assembly, low failure rate, and high durability.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the embodiment of the present invention shown in the drawings will be described with an example of a sliding door energizing bracket X of the first embodiment.
[0011]
First, FIG. 1 is a schematic explanatory view of a usage state of the sliding door energizing bracket X. FIG. In FIG. 1, 1 is a sliding door, 2 is an electric lock built in the center of the open side downside of the sliding door, 3 is a door frame, and 4 is a control panel installed in the room of the building. The sliding door energizing bracket X is attached to, for example, the upper frame 1a of the sliding door 1 and the upper frame 6 of the door frame 3 facing the upper frame 1a. The sliding door energizing bracket X of this embodiment can be mounted on the vertical frame 1b of the sliding door 1 and the vertical frame 8 of the door frame 3 facing the vertical frame 1b. Considering the relationship with the embodiment, the former example will be described.
[0012]
The sliding door 1 may be a single sliding door, but in this embodiment, the sliding door 1 is a sliding type sliding door that can be opened both, and the electric lock 2 is electrically connected through the sliding door energizing metal X and the sliding door side lead wire 7. And the engaging lock 2a is engaged with and disengaged from the receiving metal fitting 9 provided in the vertical frame 8 of the door frame 3. Moreover, the control panel 4 is electrically connected to the sliding door energizing bracket X via the control panel side lead wire 10.
[0013]
By the way, the control panel 4 is electrically connected to a commercial AC power supply 11 and an input unit 12 such as a numeric keypad and a locking / unlocking means installed indoors and outdoors. The control panel side lead wire 10 generally employs a rotary solenoid that changes in the direction of electromotive force when the electric lock 2 is locked or unlocked. It is distinguished from the lock signal lead wire 10a.
[0014]
Next, FIG. 2 thru | or FIG. 6 is each explanatory drawing which showed the specific structure of the electrically-conductive metal fitting X for sliding doors. In each of these drawings, reference numeral 20 denotes a plurality (two in the embodiment) of fixed electrodes provided at intervals on the upper lid 1a of the sliding door 1. Each of these fixed electrodes 20 has a magnet 21 inside, and is connected to the electric lock 2 through the sliding door side lead wire 7 described above. Since the fixed electrode 20 is a conductor, it is preferably housed in an insulating case 22 fixedly provided in the upper collar 1a. In this case, instead of the insulating case 22, an insulating member such as an insulating plate or an insulating frame may be interposed between the upper collar 1 a and the fixed electrode 20. Further, the insulating case 22 is not necessarily required when the upper collar 1a is made of wood because the fixed electrode 20 may be directly fitted into the recess formed in the upper collar 1a.
[0015]
The size and shape of the fixed electrode 20 are not particularly limited. Preferably, the fixed electrode 20 is elongated in the length direction of the upper rod 1a (the opening / closing direction of the sliding door), and the surface of the fixed electrode 20 is in contact with the contact surface of the movable electrode 40 described later. The contact surface should be flat. Also, the insulating case 22 should be provided so that the movable electrode 40 does not come into contact with the upper lid 1a of the sliding door, and preferably protrudes somewhat from the upper end surface of the upper lid 1a. Further, the mounting position of the fixed electrode 20 has to correspond to the mounting position of the movable electrode 40. However, the fixed electrode 20 is made of a conductive metal, and the sliding door side lead wire 7 is connected to the electric lock side electric wire. In view of the ease of the above, it is desirable that the upper end 1a of the sliding door 1 should be the sliding door opening side end.
[0016]
Next, reference numeral 30 denotes an insulating support box attached to the upper frame 6 of the door frame 1. The support box 30 is preferably fitted into the upper frame 6 so as to face the fixed electrode 20, and is fixed to the upper frame 6 via a fixing tool 31.
[0017]
Thus, in this embodiment, the support box 30 includes a mounting flange portion 33 having a screw hole 32 with which the fixing tool 31 engages, and a fitting box portion 34 provided continuously to the mounting flange portion 33, and the fitting is performed. A plurality of electrode storage guide portions 35 formed in the back (vertical) direction from the attachment flange portion 33 are formed in the joint box portion 34. Two of these electrode storage guide portions 35 are provided at intervals. The fitting box portion 34 is formed with lead wire space portions 37 communicating with the two electrode storage guide portions 35 via the guide small holes 36 and 36, respectively, and the lead wires 10a and 10b on the control panel side described above. Lead wire introduction window 38 is formed.
[0018]
The upper wall 30a of the support box 30 is detachable in consideration of the convenience of connection with the lead wire 10 on the control panel side, but the upper wall 30a is not necessarily depending on the method of connecting the lead wires. There is no need to provide it.
[0019]
Next, reference numeral 40 denotes a plurality of movable electrodes that are movably provided in the support box 30 and are always biased in the backward (upward) direction by the spring force of the spring member 41 built in the electrode storage guide portion 35. . Since the movable electrode 40 is constantly urged in the direction of the electrode storage guide 35 by the spring member 41, the movable electrode 40 is retracted into the electrode storage guide 35 by the spring force of the spring member 41 when the sliding door 1 is opened. On the other hand, when the sliding door 1 is closed, it pops out of the electrode storage guide portion 35 against the spring force of the spring member 41 and contacts the above-described fixed electrode 20.
[0020]
Thus, the movable electrode 40 includes a prismatic contact portion 43 having a magnet 42 that is attracted to the fixed electrode 20 in accordance with the polarity of the magnet 21 of the fixed electrode 20, and one side surface of the prismatic contact portion 43 ( A guide bar 44 extending from the upper surface through the guide small hole 36 to the lead wire space 37, and a flange-like stopper 45 provided around the projecting upper end portion (terminal portion) of the guide bar 44; The control panel side lead wires 10a and 10b are connected to the protruding upper end of the guide bar 44, respectively.
[0021]
The upper end portion of the spring member 41 described above is appropriately attached to the edge portion of the guide small hole 36 of the support box 30, while the lower end portion is appropriately attached to one side surface of the contact portion 43 of the movable electrode 40.
[0022]
In the above configuration, FIGS. 2 and 3 are explanatory diagrams showing energized states when the sliding door 1 is closed. In this case, since the two fixed electrodes 20 of the sliding door 1 enter below the two movable electrodes 40 in the support box 30, the movable electrodes 40 resist the spring force of the spring member 41. Then, it jumps out of each electrode storage guide portion 35 and is attracted to the opposing fixed electrode 20. Therefore, a lock signal or an unlock signal can be sent from the control panel 4 to the electric lock 2 via the lead wire 10, the sliding door energizing bracket X, and the lead wire 7.
[0023]
On the other hand, FIG.4 and FIG.5 is each explanatory drawing which shows the non-energized state at the time of opening of the sliding door 1. FIG. For example, when the unlocking signal is sent to the electric lock 2 through the unlocking signal lead wire 10b, the sliding door energizing metal fitting X, etc. while the sliding door 1 is closed, the engaging lock 2a of the electric lock 2 is received from the receiving metal fitting 7. Come off. Therefore, when the sliding door 1 is opened, the two fixed electrodes 20 gradually move away from each other without sliding from the projecting movable electrode 40 on the support box 30 side. Then, the two movable electrodes 40 are retracted into the electrode storage guide portions 35 by the spring members 41, respectively.
[0024]
【Example】
In the first embodiment shown in FIGS. 2 to 6, the support box 30 having the movable electrode 40 is mounted in the upper part of the vertical frame 8 of the door frame 3, while the fixed electrode 20 is opposed to the movable electrode 40. You may fix in the vertical fence 1b of the sliding door 1 so that it may do.
[0025]
The fixed electrode 20 includes the magnet 21, but the magnet 21 is not necessarily included, and may be provided on the upper surface of the fixed electrode 20, for example. In short, the fixed electrode 20 and the magnet 21 may be integrated. This also applies to the relationship between the movable electrode 40 and its magnet 42.
[0026]
The spring member 41 provided in the electrode storage guide portion 35 is not necessarily provided in the electrode storage guide portion 35. For example, the spring member 41 is provided in the lead wire space 37 of the support box 30 and supports the upper end portion of the spring member. On the other hand, the lower end portion of the upper wall 30a of the box 30 may be attached to the protruding upper end portion of the movable electrode 40 or the stopper 45, respectively.
[0027]
Further, as shown in FIG. 7, the support box 30A and the fixed electrode 20A are exchanged so that the support box 30A provided with the movable electrode 40A faces the upper arm 1a of the sliding door 1A, while the fixed electrode 20A faces the movable electrode 40A. You may attach fixedly in the upper frame 6a of the door frame 3A. In this case, it is desirable not to form the mounting flange portion on the insulating case 22A in which the two fixed electrodes 20A are fitted. Then, since the insulating case 22A and the fixed electrode 20A are located on the same horizontal plane as the edge of the upper frame 6a of the door frame 3A, the flange portion 33A of the support box 30A provided with the movable electrode 40A can be used case by case. You may make it protrude from the upper collar 1a of 1A of sliding doors.
[0028]
Further, as shown in FIGS. 8 and 9, only one of the fixed electrode and the movable electrode may integrally have a magnet, and the other may be a simple metal plate. That is, in the embodiment of FIG. 8, in the first embodiment, the fixed electrode 20B is a simple conductive metal member (block, plate, etc.) and does not have magnets inside or on the side. On the other hand, in the embodiment of FIG. 9, in the first embodiment, the prismatic contact portion 43B of the movable electrode 40B is simply a conductive metal member (block, plate, etc.), and a magnet is provided on the inside or side. I don't have it.
[0029]
Thus, even if one is a conductive metal member and the other is a conductive metal member that is adsorbed to the metal member, the same effect as in the first embodiment can be achieved.
[0030]
【The invention's effect】
As is clear from the above description, the present invention has the following effects.
(1) When the sliding door is closed, the movable electrode pops out of the door frame or the sliding door against the spring force of the spring member and comes into contact with the fixed electrode. On the other hand, when the sliding door is opened, the movable electrode is retracted into the door frame or the sliding door by the spring force of the spring member. Therefore, the current-carrying metal fittings can be attached not only to the upper frame of the sliding door and the upper frame of the door frame, but also to “inside the vertical frame” of the door frame and “vertical frame” of the sliding door.
(2) Since a magnet-integrated fixed electrode and a magnet-integrated movable electrode that is attracted according to the polarity of the fixed electrode are used, and the contact surface of one electrode (for example, the fixed electrode) is large , Even if a member does not require a certain level of skill, the current-carrying bracket can be attached in a so-called “about feeling”.
(3) The movable electrode moves away from the fixed electrode when the sliding door is opened, and substantially retracts into the door frame or the support box in the sliding door. Therefore, it is possible to easily remove the sliding door from the door frame when inspecting or repairing the current-carrying metal fittings.
(4) The magnetic field at the time of closing the sliding door is made as strong as possible, or the mutual contact area between the fixed electrode and the movable electrode is increased. Therefore, depending on the closed state of the sliding door or the clearance between the sliding door and the door frame. It is possible to prevent contact failure between the fixed electrode and the movable electrode. That is, there is no risk of poor contact even if the sliding door is closed with some margin, or the clearance between the upper lid of the sliding door and the upper frame of the door frame is small or large.
(5) Since the magnet-integrated fixed electrode and movable electrode are employed, the number of components is reduced. Therefore, advantages such as easy assembly, a low failure rate, and high durability can be expected.
(6) In addition, upon opening of the sliding door, when the fixed electrode slides the movable electrode, dust attached to the electrodes are removed. Therefore, contact failure due to dust adhesion can be prevented.
