Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention externally energizes an electric lock or the like which is a locking device provided in a sliding door such as a sliding door or a sliding door arranged in an opening of a building such as a house. The present invention relates to a sliding door energization structure.

[0002]

2. Description of the Related Art Sliding doors such as sliding doors and sliding doors arranged in openings such as entrances and exits of buildings such as houses and buildings are slidable in the left-right width direction with respect to the frame of the opening. In addition to being movable, it can be removed from the opening frame, that is, unlike the door, there is no part connected to the frame such as hinge parts such as hinges, and opening and closing operations are done by the building. The structure is only slidably guided with respect to.

Therefore, in order to dispose an electric lock for locking and unlocking the sliding door electrically, in order to obtain power from the outside of the sliding door, the frame side and the sliding door are connected by a curl cord which is expandable and contractible. A structure for making a physical connection was used.

However, since the curl cord having the above-mentioned current-carrying structure is exposed to the outside, it has an external appearance.
It has a drawback that it is unattractive and, because it repeatedly expands and contracts due to the opening and closing operation of the sliding door, it is liable to deteriorate and a wire breakage may occur, resulting in improper energization of the electric lock.

From this, a metal fitting for energizing an electric lock for a sliding door has been devised, for example, Japanese Utility Model No. 3-12.
A device for energization disclosed in Japanese Patent No. 128 is conventionally used. In this energizing device, contact bodies are respectively arranged on the door-edge-side upper edge of the sliding door and a frame facing the upper edge when the door is closed, and between the sliding door upper-edge side contact body and the frame-side contact body. , Provided with a movable cover arranged on the frame side to cover the contact body,
The cover is opened by a door closing operation, and the contact bodies are brought into contact with each other in a conductive manner when the door is closed.

[0006]

However, in the above-described conventional energizing device, the movable cover is provided on the frame side, but the cover is opened by the sliding door tip, that is, Since the cover is configured to open by engaging the sliding door,
The cover is formed with a protrusion to engage with the sliding door, and this protrusion protrudes inside the building opening, making it look unattractive and easy to handle by hand because this operating part is exposed. There was a problem that it was opened and closed.

Further, in this energizing device, one of a pair of contact bodies that come into contact with each other is projected by a spring. However, since the contact body is pivotally attached and pivoted, it projects. However, there are drawbacks in that the case for accommodating the contact bodies cannot be downsized and the number of the contact bodies cannot be easily increased.

Therefore, in order to solve the above problems, the present invention can be constructed in a small space even if the number of the energizing contacts arranged on the sliding door side and the frame side is increased, and surely contact each other. It is an object of the present invention to provide a current-carrying structure for a sliding door that has a good-looking exterior structure.

The urging force of the compression coil spring 17 is always applied to the movable block 12, and the urging force causes the tip 12a of the movable block 12 to open the one end 5a of the case 5, that is, the tip of the cover plate 7. The movable block 12 is always protruded from the 7a side.
In the state where 2a is projected, each fixed contact 13 does not correspond to the through hole 8 of the cover plate 7 and becomes the lower part of the concealing portion 9, so that each fixed contact 13 is not exposed.

The projecting length of the movable block 12 is the same as that of the regulating projection 15 provided on the bottom surface of the movable block 12.
Is abutted on the end surface of the plate portion 6 in the case 5, so as to be flush with the one end surface 5a of the case 5 main body as shown in FIG.

The sliding door unit 2 includes a sliding door 4
At the upper edge of the side, the cover plate 7 is substantially flush with the upper end surface in the recess 4a in which the door front end surface and the upper end surface are notched in a rectangular concave shape, that is, parallel to the moving direction of the sliding door 4. The movable block 12 is attached to the lower part of the cover plate 7 so as to be slidable in parallel with the moving direction of the sliding door 4 along the cover plate 7.

Next, the frame side unit 3 is a frame body of an opening for guiding the sliding movement of the sliding door 4 described above, and is arranged on the upper frame 20 facing the upper edge of the sliding door 4, and serves as the other block. The fixed block 21, the convex portion 23, and the movable contact 24 as the other contact are generally configured.

The fixed block 21 is, as shown in FIG.

The convex portion 23 is provided. The thickness of the convex portion 23, that is, the other end surface 2 of the fixed block 21.
The length of protrusion from 1b is set to be substantially equal to the length between the through holes 8 in the cover plate 7.

The position of each guide hole 22 is determined by the convex portion 23.
With reference to the vertical surface 23a, the distance from the vertical surface 23a is set and arranged.

Next, the movable contact 24 is a plate-like member whose tip is formed in a substantially triangular shape, and is composed of a plurality of, i.e., nine, corresponding to each fixed contact 13 arranged in the movable block 12. .

Each of these movable contacts 24 is arranged on the substrate 14 such as a printed wiring board via a biasing guide portion 25.

The biasing guide portion 25 is disposed on the lower surface of the base plate 26, and a pair of conductive guide members 27 are planted vertically downward with respect to the plate surface of the base plate 26, and between the conductive guide members 27. And a compression coil spring 28 having conductivity, one end of which is fixed to the substrate 26, and the movable guide 24 is connected to the conduction guide member 27 of the biasing guide member 25.
Both side edges are supported and the other end of the compression coil spring 28 is connected to the base end of the movable contact 24 so that the movable contact 24 can slide between the conduction guide members 27.

Then, each conduction guide member 27 is fitted and inserted along the wall surface in each guide hole 22 of the fixed block 21, and the substrate 26 is fixed to the upper surface of the fixed block 21.
The tip of each movable contact 24 is adapted to protrude from the bottom surface of the fixed block 21.

On the lower surface of the fixed block 21,
A through hole 29 slightly smaller than each guide hole 22 is formed and a thin stopper plate 30 that also serves as a decorative plate is attached, so that the movable contact 24 does not fall out of each guide hole 22 and the movable contact 2
Only the tip of 4 is projected.

As a result, each movable contact 24 can move up and down with respect to the substrate 26, and the compression coil spring 28 can be moved.
Due to the urging force of the fixed block 21, the fixed block 21 is always projected from the lower surface.

An electric wire 31 such as a signal line or a power supply line is connected to each movable contact 24 through the biasing guide portion 25 and the substrate 26, as shown in FIG.

The frame-side unit 3 is a frame body having an opening for guiding the sliding movement of the sliding door 4, and the upper frame 20 facing the upper edge of the sliding door 4, in the present embodiment, the door of the sliding door 4. In the upper frame 20 located at the joint with the vertical frame 19 with which the tip abuts,
The fixing block 21 is attached in such a manner that the bottom surface (stopper plate 30) of the fixed block 21 is substantially flush with the lower surface of the upper frame 20, and the convex portion 23 only is provided. The convex portion 23 is provided so as to project from the lower surface of the upper frame 20 and project from the door end contact surface of the vertical frame 19.

Although not shown in the figures, each of the units 2 and 3 described above is connected to the sliding door side unit 2 with an electric lock arranged at the door end of the sliding door 4, and the frame side unit 3 is connected to a commercial power source or the like. It is connected to a power source and a control unit (not shown).

Next, the operation of the sliding door energizing structure 1 having the above-described structure will be described. First, in the state where the sliding door 4 is opened, in the sliding door side unit 2, the movable block 12 is pressed toward the front end of the case 5 by the urging force of the compression coil spring 17, that is, the front end 12 a of the movable block 12 is covered by the cover plate 7. The fixed contacts 13 are projected from the tip 7a side and are hidden by the concealing portion 9 of the cover plate 7 (see FIG. 3).

Further, in this open state, the frame side unit 3
Each movable contact 24 is in a state of protruding downward.
The electric lock arranged at the door end of the sliding door 4 is not energized, and locking operation and the like are impossible.

Next, when the sliding door 4 is closed and the door end of the sliding door 4 is brought closer to the vertical frame 19 on the building side, first, as shown in FIG. 3, the convex portion of the frame side unit 3 (fixed block 21) is projected. The front end surface 12a of the movable block 12 of the sliding door side unit 2 contacts the vertical surface 23a.

In this abutting state, the fixed contacts 13 and the movable contacts 24 are vertically opposed to each other with the concealing portion 9 of the cover plate 7 interposed therebetween.

Further, when the closing operation progresses and the door tip of the sliding door 4 comes into contact with the vertical frame 19 to bring the door into the closed state, only the movable block 12 is moved by the convex portion 23 of the fixed block 21, as shown in FIG. The movable block 12 is pressed, that is, the movable block 12 slides in the retracted direction with respect to the case 5 against the biasing force of the compression coil spring 17.

In other words, the movable block 12 has the convex portion 2
3 stays at the position of the fixed block 21 through 3, and the case 5 moves together with the sliding door 4 against the biasing force of the compression coil spring 17 with respect to the fixed block 21.

Then, the concealing portion 9 that separates the opposing contacts 13 and 24 is moved by the thickness of the convex portion 23, whereby each fixed contact hidden by the concealing portion 9. 13 is the position of each through hole 8 of the cover plate 7 and is exposed.

At this time, each movable contact 24 slides on the upper surface of the concealing portion 9 of the cover plate 7 as the sliding door 4 moves, and together with this closing, each movable contact 24 has a biasing force in the downward direction. Therefore, it comes into direct contact with each fixed contact 13 through each through hole 8 of the cover plate 7.

As a result, the contacts are energized through the contacts 13 and 24, the electric lock of the sliding door 4 obtains a power source, and a signal can be transmitted to and from the control unit to enable a locking operation.

Further, when the door is opened from the closed state, the cover plate 7 is moved by the biasing force of the compression coil spring 17 at the same time when the sliding door 4 is detached from the vertical frame 19. It intervenes between the contact 24 and each fixed contact 13 to cut off the energization state by each contact 13, 24.

In other words, when the door opening operation is performed and the door end of the sliding door 4 is separated from the vertical frame 19, the movable block 12 is projected onto the convex portion 23 of the fixed block 21 by the urging force of the compression coil spring 17 against the sliding door 4. The cover plate 7 moves together with the sliding door 4 while being in contact with the contact plate 13, that is, in the state where the contacts 13 and 24 face each other, and the cover plate 7 is placed between the contacts 13 and 24.
The concealing unit 9 of moves. Then, the energization state of each contact 13, 24 is cut off.

Thereafter, the front end surface 12a of the movable block 12 is
Project from the sliding door 4 (cover plate 7) to a position flush with the door end of the sliding door 4, and the tip surface 12a of the movable block 12
Is separated from the vertical surface 23a of the convex portion 23, and the sliding door 4 is opened.

Therefore, in the sliding door energizing structure 1 thus configured, the movable contact 24 of the pair of contacts is provided on the frame 20 side, and the compression coil spring 2 having the biasing force in the straight downward direction is provided.
At 8, the fixed contacts 13 on the upper edge side of the sliding door 4 facing each other are brought into contact with each other, so that the connection state between them becomes a structure having good conductivity,
The energized state becomes reliable and the reliability is improved. Further, this ensures the operation of the electric lock connected to this energization structure.

Further, since the movable contact 24 has a structure that slides in the vertical direction, even if a plurality of movable contacts 24 are arranged vertically and horizontally, the size can be reduced and the space can be saved. As a result, the installation space on the sliding door 4 side and the frame 20 side, where the energization structure 1 is attached, is not made large.

Further, according to the sliding door energizing structure 1, when the door is closed, the movable block 12 first comes into contact with the convex portion 23 of the fixed block 21, and the movable block 1 is inserted through the convex portion 23.
2 stops, the movable contact 24 and the fixed contact 13 are made to face each other across the cover plate 7, and then the cover plate 7 moves with respect to the movable block 12 as the sliding door 4 moves.
The contacts 13 and 24 are in contact with each other to be in a conductive state. That is, in a state where the tip end surface 12a of the movable block 12 is in contact with the vertical surface 23a of the convex portion 23, the movable block 12 is substantially integrated with the fixed block 21 via the convex portion 23, and these blocks 12, 21 On the other hand, the cover plate 7 substantially integrated with the sliding door 4 via the compression coil spring 17 is provided.
Will be arranged. Therefore, the position of the fixed contact 13 does not move with respect to the movable contact 24, and the cover plate 7 is kept together with the sliding door 4 after maintaining the position where they are directly opposed.
Since the contact points 13 and 24 are moved between the contact points 13 and 24 by the movement of No. 3, no positional deviation occurs when the contact points 13 and 24 are in contact with each other, so that electricity can be supplied reliably and quickly.

Further, the cover plate 7 is provided substantially integrally with the sliding door 4, and the movable block 12 is provided with the convex portion 23 of the fixed block 21.
After the door is in contact with the door and the door is substantially integrated as described above, the moving distance between the door tip of the sliding door 4 and the vertical frame 19 is a distance at which only the compression coil spring 17 operates. The operation against the urging force is a door closing operation that also functions as the operation of sliding the movable block 12 with respect to the cover plate 7, and between the operations against the urging force,
Since both contacts 13 and 24 are already in the facing position, there is no other member that follows or interlocks with the operation of the sliding door 4, and malfunctions or malfunctions due to energization are less likely to occur, and damage is less likely to occur.

Further, in the above embodiment, the cover plate 4
Is disposed on the sliding door 4 side that slides with respect to the building, that is, on the moving body side, so that the contacts (fixed contact 13) disposed on the upper edge of the sliding door where dust or the like is likely to adhere is not contaminated. , There is no risk of contact failure.

Further, since the sliding bias of the movable block 12 is constituted not by the tension coil spring but by the compression coil spring 17 having better durability as compared with the tension coil spring, damage due to aging is less likely to occur. A good operation can always be obtained.

Further, since the movable block 12 is moved by the compression coil spring 17 at the same time when the sliding door 4 is opened, and the fixed contact 13 is automatically hidden by the cover plate 7, the fixed contact 13 is required. When the fixed contact 13
It is possible to obtain a good contact state without oxidation of the surface of.

In addition, in this sliding door energizing structure 1, there are few members that largely project from the edge portion of the opening of the building and the edge portion of the sliding door 4 on the door front side, and the appearance of the opening and the sliding door 4 does not deteriorate.

In the above-described embodiment, an example of a structure in which the movable block 12 is provided on the sliding door 4 side, the unit 2 provided with the cover plate 7 is arranged, and the frame 20 side is the fixed block 21 is described. But the sliding door 4 side is fixed block 21
The movable block 12 is provided on the frame 20 side, and the frame 20
The cover plate 7 may be arranged on the side.

In this case, when the door is open, the contact on the frame 20 side is not exposed and is hidden by the cover plate 7,
That is, it is possible to prevent a person from touching the contact when the door is open, preventing an electric shock accident, etc., and obtaining an anticorrosive effect on the contact.

Also, an example was described in which the contact on the movable block 12 side provided with the cover plate 7 was the fixed contact 13 and the contact on the fixed block 21 side was the movable contact 24, but this energization structure is not limited to this. Instead, at least one of the contacts facing each other when the door is closed may be configured to be in electrical contact with each other.

[0063]

As described above, in the sliding door energizing structure according to the present invention, since the pair of contacts are in a positional relationship of directly facing each other across the through hole of the cover plate, the contact state between both contacts is high. Since a protruding biasing member is provided on at least one of the paired contacts, the biasing force in the straight opposite direction makes it possible to further improve the electrical connection between them. Therefore, there is an effect that the energized state becomes reliable and the reliability is improved.

Further, from this, the operation of the electric lock connected to the current-carrying structure is ensured.

Further, since the protruding contacts are structured to slide in the straight direction, it is possible to reduce the size even if a plurality of them are arranged vertically and horizontally, and it is possible to save space. There is an effect.

As a result, it is possible to obtain the effect that the mounting space on the sliding door side and the frame side where the energizing structure is mounted is not required to be large.

Further, according to this current-carrying structure for sliding doors, when the door is closed, first, the two blocks are mutually stopped by the convex portion, the respective contacts of the respective blocks are made to face each other across the cover plate, and thereafter, With the movement of the sliding door, one of the blocks is slidably moved with respect to the cover plate to bring the respective contacts into contact with each other to bring them into an energized state. That is, both blocks are substantially integrated via the convex portion, and the cover plate is arranged for these blocks via the biasing member. Therefore, the position of one contact does not move with respect to the other contact, and after maintaining the position directly facing,
Since the cover plate is configured to move from one contact point to another with respect to these contact points due to the movement of the sliding door, there is no positional displacement when the contact points are in contact with each other, and the current can be supplied reliably and quickly. There is.

Further, the cover plate is provided substantially integrally with the sliding door or the frame, and after the both blocks are substantially integrated with each other via the convex portion when the door is closed, the sliding movement of the door end of the sliding door and the vertical frame is performed. The interval is an interval at which only the urging member operates, and the operation against the urging force of this urging member is a door closing operation that also functions as sliding one block with respect to the cover plate, Also, during the operation against this biasing force, both contacts are already facing each other, so there is no other member that follows or interlocks with the operation of the sliding door, and it is unlikely that malfunctions or malfunctions due to energization will occur. Moreover, there is an effect that damage is unlikely to occur.

Further, when the cover plate is arranged on the sliding door side which slides with respect to the building, that is, on the moving body side, the contacts arranged at the upper edge of the sliding door to which dust and the like are likely to adhere are dirty. Therefore, there is no possibility of causing contact failure.

Further, when the sliding door is opened, one block is slidably moved by the biasing member, and the contact is automatically hidden by the cover plate. Since it is always protected except when, the surface of this contact does not oxidize and a good contact state can be obtained.

In addition, in this energizing structure for a sliding door, there are few members that project largely from the edge portion of the opening of the building and the edge portion of the sliding door on the door front side, and there is an effect that the appearance as the opening and the sliding door does not deteriorate. .
