Description

  The present invention relates to an energizing device for a sliding door for energizing an electric lock side lead wire attached to the sliding door and a control panel side lead wire provided on the door frame side.

  Conventionally, as an energizing device for this type of sliding door, the one described in Japanese Patent No. 3719311 (Patent Document 1) is known. The energizing device for a sliding door described in this publication includes a magnet-integrated fixed electrode that is attached to a sliding door and connected to an electric lock via a sliding door lead wire, and an electrode storage guide portion that is attached to the door frame. And a support box that is movably provided in the support box, and is always urged in the backward (door frame) direction by the spring force of the spring member provided in the support box, and leads on the control panel side And a magnet-integrated movable electrode connected to the magnet. The movable electrode includes a contact portion having a magnet that is attracted to the fixed electrode corresponding to the polarity of the magnet of the fixed electrode, and the support box penetrating the guide small hole of the support box from one side of the contact portion. The guide bar extends to the lead wire space and a stopper provided at the upper end of the guide bar. When the sliding door is closed, the movable electrode is moved from the electrode storage guide of the support box to the spring member. The flat contact portion of the fixed electrode slides with respect to the movable electrode when the sliding door is opened.

Japanese Patent No. 3719311

  However, in the energizing device for sliding doors described in Patent Document 1, the fixed electrode formed integrally with the magnet is fixed to the cage of the sliding door, and the movable electrode formed integrally with the magnet is placed in a support box fixed to the door frame. The movable electrode is always urged and stored in the backward direction by a spring, and when the sliding door is closed, the movable electrode protrudes from the support box in the sliding door direction against the spring force of the spring member and is attracted to the fixed electrode. Therefore, when the gap between the upper end of the sliding door and the door frame is large, or when the sliding door rattles due to wind or human operation, only one movable electrode side is energized as in this conventional example. In the energizing device for sliding doors, when the sliding door is closed, there is a possibility that the sliding door side electrode and the frame side electrode are not reliably in contact with each other and a contact failure may occur.

  Moreover, in this thing of this patent document 1, since only a movable electrode moves with respect to a fixed electrode as mentioned above, when the clearance gap between the upper end of a sliding door and a door frame is large, or a wind or a person's When the sliding door is rattled by operation, the positional relationship of the contact part of the fixed electrode and the movable electrode is shifted, and electrical noise is generated, which has a bad influence on the contact failure and control circuit etc. There was a problem.

  Furthermore, in this Patent Document 1, when the sliding door is opened, the flat contact portion of the fixed electrode slides with respect to the movable electrode, and the contact is polished to remove dust attached to each electrode. When the sliding door is closed, until the sliding door is completely closed (that is, until the magnet on the fixed electrode side and the magnet on the movable electrode side are attracted to each other), the magnets repel each other. There is a problem that the dust attached to each electrode cannot be removed.

  The present invention has been devised in order to solve the above-described problems, and the sliding door side electrode and the frame side electrode are always urged in the opposite directions to move independently, thereby allowing the sliding door to move independently. Even when the gap between the upper end and the door frame is large, or when the sliding door rattles due to wind or human operation, the two electrodes are reliably contacted to prevent contact failure. In addition, by storing the frame-side electrode built-in body in a floating state in the case, when the sliding door is closed, the sliding door-side magnet and the frame-side magnet attract each other, so that the contact between the sliding door-side electrode and the frame-side electrode is brought into contact. Misalignment of the portion can be prevented, and no electrical noise is generated. Furthermore, the sliding door side electrode and the frame side electrode slide against each other not only when the sliding door is opened but also when the sliding door is closed, so that the contact is polished and dust attached to each electrode is removed. It is an object of the present invention to provide an energizing device for a sliding door that exhibits the excellent effect of the above.

  In order to solve the above-described problem, the sliding door energizing device according to claim 1 of the present invention is different from the sliding door side electrode connected to one end of the sliding door side lead wire to which the electric lock is connected, and the sliding door side electrode. The sliding door side electrode built-in body having the sliding door side magnet provided on the body is provided on the sliding door, and this sliding door side electrode built-in body is normally urged by a spring so as to jump out in the door frame side direction. A frame-side electrode built-in body having a frame-side electrode connected to one end of the lead wire and a frame-side magnet provided separately from the frame-side electrode is provided on the door frame, and the frame-side electrode built-in body is a spring. The frame-side electrode built-in body is housed in a case having an opening at the front, and the sliding door is interposed between the frame-side electrode built-in body and the case. Play is formed in the opening / closing direction of the door and the thickness direction of the sliding door. When the door is closed, the sliding door side magnet and the frame side magnet are attracted to each other and the sliding door side electrode and the frame side electrode come into contact with each other until they are completely closed and are in an energized state. When the sliding door side electrode and the frame side electrode are in contact with each other, the sliding door side magnet and the frame side magnet are in a non-energized state when they slide and come into contact with each other. It is characterized by.

  Further, in the energizing device for sliding doors according to claim 2, the sliding door side electrode built-in body and the frame side electrode built-in body have an inclined end surface that faces each other when the sliding door is closed from the open state. is there.

  According to the first aspect of the present invention, the sliding door-side electrode built-in body having the sliding door-side electrode and the sliding door-side magnet and provided on the sliding door is urged by the spring so as to always jump out in the door frame side direction. The frame-side electrode built-in body that has the frame-side electrode and the frame-side magnet and is provided on the door frame is urged by a spring so as to always pop out in the sliding door side direction, so that the sliding door is completely closed Then, in addition to the biasing force of the spring of the sliding door side electrode built-in body and the biasing force of the spring of the frame side electrode built-in body acting from both toward the center of the gap, the sliding door side magnet and the corresponding frame side magnet and Due to the synergistic effect of the magnetic attraction force, the sliding door side electrode built-in body and the frame side electrode built-in body are completely and securely held in a normal conductive state, and the sliding door side electrode and the frame side electrode are firmly and reliably Contact. Therefore, even when the gap between the upper end of the sliding door and the door frame is large or when the sliding door rattles due to wind or human operation, both electrodes are reliably contacted to prevent poor contact.

  The frame-side electrode built-in body is housed in a case having an open front part, and play is formed between the frame-side electrode built-in body and the case in the sliding door opening / closing direction and the sliding door thickness direction. Therefore, when closing the sliding door, the position of the sliding door side electrode built-in body and the frame side electrode built-in body is determined by attracting the sliding door side magnet and the frame side magnet, and when one electrode built-in body moves, The other electrode built-in body follows the magnetic attraction force. Therefore, it is possible to prevent the displacement of the contact portion of the contact between the sliding door side electrode and the frame side electrode, the occurrence of electrical noise is eliminated, and the influence on the control circuit can be avoided.

  Furthermore, when the sliding door is closed, the sliding door side magnet and the frame side magnet are attracted to each other, and the sliding door side electrode and the frame side electrode come into contact with each other until they are completely closed. When opened, if the sliding door side electrode and the frame side electrode are in contact with each other and slide, the sliding door side electrode and the frame side electrode are not energized. Therefore, not only when the sliding door is opened, but also when the sliding door is closed, the sliding door side electrode and the frame side electrode slide against each other to polish the contacts, and dust attached to each electrode is removed. Excellent cleaning effect such as

  According to the second aspect of the present invention, the sliding door-side electrode built-in body and the frame-side electrode built-in body have an inclined end surface facing each other when the sliding door is closed from the open state. When closing from the open state, even if the facing end faces of the sliding door side electrode built-in body and the frame side electrode built-in body come into contact with each other, they are pushed into each other by the action of the slope of the starting end face. It has the effect that the closing operation can be performed smoothly without any trouble.

An embodiment of the present invention will be described below with reference to FIGS.
FIG. 1 is a front view showing an example of a usage state in which an energizing device for a sliding door according to the present invention is attached. In FIG. 1, a is a sliding door such as a single sliding door or a sliding door, and the opening b3 of the door frame b is opened or closed by the sliding door a. Reference numeral 1 denotes an electric lock attached to the vertical rod a1 of the sliding door a, and 10 denotes an energizing device for the sliding door. In this embodiment, the upper door a2 of the sliding door a and the door facing the upper rod a2 in the closed state It is attached to the upper frame b2 of the frame b. The electric lock 1 is electrically connected to the energizing device 10 for the sliding door via the sliding door side lead wire 25, and is provided in the electric lock 1 by supplying or stopping current to the sliding door side lead wire 25. The lock 2 is engaged with and disengaged from the receiving hole 3 provided in the vertical frame b1 of the door frame b. Further, the control panel side lead wire 35 is electrically connected to the other side of the energizing device 10 for the sliding door via the control panel 5 connected to the power source 4.

  A specific configuration of the sliding door energization device 10 will be described in detail below with reference to FIGS. The energizing device for the sliding door is roughly divided into a sliding door side unit 20 attached to the upper frame a2 of the sliding door a and a frame side unit 30 attached to the upper frame b2 of the door frame b.

  The sliding door side unit 20 includes an insulating case 21 having a storage chamber 21a having a U-shaped cross section and a flange portion 21b extending in the left-right longitudinal direction of the opening edge of the storage chamber 21a, and a storage chamber for the case 21 21a is provided with an insulating sliding door side electrode built-in body 23 which is installed so as to be able to protrude and retract from the opening 21a1 of the case 21.

  For example, the sliding door side electrode built-in body 23 forms a rectangular case with a substantially U-shaped cross section, as shown in FIGS. 2, 4, and 5. And the side facing the frame side unit 30), the sliding door side electrodes 24, 24 are provided apart from each other near the center in the longitudinal direction, and the above sliding door side leads are provided below the sliding door side electrodes 24, 24. One ends of the lines 25 and 25 are connected. Near the both ends in the left-right longitudinal direction of the case, there are provided sliding door side magnets 26, 26 which are separated from the sliding door side electrodes 24, 24 and are different from each other.

  And when assembling the said sliding door side electrode built-in body 23 and the case 21, before fixing the front board 21c to the upper surface (front surface) of the collar part 21b of the case 21, for example, the sliding door side lead wire 25 or the sliding door side is beforehand taken. Springs 27, 27 such as coil springs are inserted into spring-insertion cylinders 21d, 21d formed on the lower side (rear surface side) of the sliding door-side electrode built-in body 23, to which the electrodes 24, 24 and the sliding door-side magnets 26, 26 are assembled. To do. After housing the sliding door side electrode built-in body 23 in this state in the housing chamber 21 a of the case 21, the front plate 21 c is crimped to the flange portion 21 b of the case 21 with, for example, caulking pins 21 e, and the case 21 and the sliding door side electrode built-in body 23 are placed. It is good to assemble. Therefore, as shown in FIGS. 4 and 14, the sliding door side electrode built-in body 23 is normally urged so as to protrude in the door frame side direction by the springs 27 and 27. At this time, in the sliding door side electrode built-in body 23, the flange 21d1 protruding from the outer peripheral wall of the spring-fitted insertion tube 21d is locked to the inner flange 21c1 of the front plate 21c, and further protrusion is restricted. .

  As described above, in a state where the sliding door side electrode built-in body 23 and the case 21 are assembled, the case 21 is fitted into the storage portion a21 formed on the upper lid a2 of the sliding door a, and is attached to the front plate 21c and the flange portion 21b. It fixes with the screw | thread 28 etc. through the formed hole.

Since the sliding door side unit 20 is configured as described above, when the sliding door side magnet 26 is not close to the frame side magnet 36 of the frame side unit 30, that is, when the sliding door is opened, FIG. 14, the sliding door side electrode built-in body 23 pops out in the door frame side direction by the urging force of the spring 27 (until 21d1 is locked to 21c1). Further, as shown in FIG. 5, when the sliding door side electrode built-in body 23 is pressed against the urging force of the spring 27 in the direction of the arrow A, the lower end portion of the spring fitting insertion tube 21 d comes into contact with the case 21. Moved down to position. Furthermore, when the sliding door is closed, as shown in FIG. 2, the sliding door side magnet 26 of the sliding door side electrode built-in body 23 and the frame side magnet 36 of the frame side electrode built-in body 33 of the frame side unit 30 face each other. 2, the sliding door side electrode built-in body 23 is shown in FIG. 2 due to the balance between the attractive force between the magnets and the springs 27, 27 of the sliding door side electrode built-in body 23 and the spring 37 of the frame side electrode built-in body 33. It protrudes in the door frame side direction. When the sliding door a is opened, as shown in FIG. 14, the sliding door side electrode built-in body 23 and the frame side electrode built-in body 33 protrude from the cases 21 and 31 by the biasing force of the springs 27 and 37.
When the sliding door a is closed, the inclined surface 23c of the sliding door side electrode built-in body 23 of the sliding door side unit 20 and the frame side electrode built-in body 33 of the frame side unit 30 as shown in FIG. 33c abut, and the sliding door side electrode built-in body 23 and the frame side electrode built-in body 33 retreat against the springs 27 and 37, respectively, due to the action of the inclined surface. Further, when the sliding door is closed and completely closed, the state shown in FIG. 2 is obtained. In addition, in the state of FIG. 13, the magnets 36 and 26 are subjected to a repulsive force, but the repulsive force does not cause the sliding door side electrode built-in body 23 and the frame side electrode built-in body 33 not to contact (separate). It is preferable to do so.

The frame side unit 30 includes an insulating case 31 having a storage chamber 31a having a U-shaped cross section and a mounting plate 31b extending in the left-right longitudinal direction of the opening edge of the storage chamber 31a, and a storage chamber for the case 31 An insulating frame-side electrode built-in body 33 is provided in 31a so as to be able to appear and retract.
Note that an opening 3b1 for the frame-side electrode built-in body 33 to appear and disappear is formed from the longitudinal center of the mounting plate 31b to near both ends.

  The frame-side electrode built-in body 33 forms a case having a substantially U-shaped cross section and a substantially rectangular outer shape, for example, along FIGS. 2 and 6 to 11, and is formed at the center of the case. A spring 37 such as a coil spring is fitted into the recessed portion 31d. The spring 37 biases the frame-side electrode built-in body 33 in the sliding door direction. On the lower side of the case (in FIG. 2, the side facing the sliding door side unit 20), leaf spring-like frame-side electrodes 34, 34 are provided apart from each other near the approximate center in the left-right longitudinal direction. One end of the control panel side lead wires 35, 35 is connected to a part of the side electrodes 34, 34, and the other end is led out from the lead wire introduction hole 31 c of the case 31 and connected to the control panel 5.

  The frame side electrode 34 is formed in a bent leaf spring shape, and the base end portion thereof is fitted into the upper end portion of the spring introduction hole 31e of the frame side electrode built-in body 33 (case body), while the tip end portion is The downward projecting portion 34 a is formed so as to be surely in contact with the sliding door side electrode 24, and the downward projecting portion 34 a is combined with the urging force of the spring 37 by springs 38, 38 such as coil springs provided near the base end portion. Thus, the sliding door side electrodes 24, 24 are urged so as to contact with each other.

  Near the both ends in the left-right longitudinal direction on the lower side of the case 31, frame-side magnets 36, 36 that are separated from the frame-side electrodes 34, 34 and have different polarities are provided.

  Next, an example in which the frame side electrode built-in body 33 and the case 31 are assembled will be described. First, frame-side electrodes 34 and 34, frame-side magnets 36 and 36, and springs 37, 38, and 38 that are connected to one end of the control panel-side lead wire 35 are assembled to the frame-side electrode built-in body 33. Next, after the frame side electrode built-in body 33 in this state is stored in the storage chamber 31a of the case 31, the mounting plate 31b is brought into contact with the opening edge of the storage chamber 31a of the case 31, and the mounting plate 31b, Is fixed with screws 39, and the case 31 and the frame-side electrode built-in body 33 are assembled (see FIG. 11). Therefore, as shown in FIGS. 6 and 14, the frame-side electrode built-in body 33 is always urged to jump out in the sliding door side direction by the springs 37 and 37. At this time, in the frame-side electrode built-in body 33, the flange 33a protruding from the outer peripheral wall of the frame-side electrode built-in body 33 is locked to the inner flange 31b2 formed at the edge of the opening 31b1 of the mounting plate 31b. The above pop-up is regulated.

  As described above, in the state where the frame-side electrode built-in body 33 and the case 31 are assembled, the case 31 is fitted into the storage portion b21 formed on the upper frame b2 of the door frame b and applied to the upper frame b2. The mounting plate 31b is fixed to the upper frame b2 with screws 41 through the holes 40 formed in the mounting plate 31b of the case.

  Since the frame side unit 30 is configured as described above, when the frame side magnet 36 does not act on the sliding door side magnet 26 of the sliding door side unit 20, as shown in FIGS. 6, 7, and 14. Moreover, the frame-side electrode built-in body 33 pops out in the sliding door side direction by the urging force of the spring 37 (until 33a is locked to 31b2). Further, as shown in FIG. 8, when the frame side electrode built-in body 33 is pressed against the urging force of the spring 37 in the door frame side direction, the upper end surface of the frame side electrode built-in body 33 comes into contact with the top plate of the case 31. Moved up. Further, when the sliding door is closed, as shown in FIG. 2, the sliding door side magnet 26 of the sliding door side electrode built-in body 23 and the frame side magnet 36 of the frame side electrode built-in body 33 of the frame side unit 30 face each other. 2, the frame-side electrode built-in body 33 is as shown in FIG. 2 due to the balance between the attractive force between the magnets and the springs 27, 27 of the sliding door-side electrode built-in body 23 and the spring 37 of the frame-side electrode built-in body 33. It protrudes in the sliding door direction.

The frame-side electrode built-in body 33 is housed in a case 31 having an open front portion (for example, the lower part in FIGS. 6 to 10), and a sliding door is provided between the frame-side electrode built-in body 33 and the case 31. A play is formed in the opening / closing direction of a and the thickness direction of the sliding door a.
That is, as shown in FIG. 9, a play m consisting of a gap is formed between the flange 33a formed on the outer wall of the frame-side electrode built-in body 33 and the outer wall 31f of the case 31, and the stroke of the play m The frame-side electrode built-in body 33 can be moved in the sliding door opening / closing direction X by an amount. Also, as shown in FIG. 10, a play n consisting of a gap is formed between the side wall 33b of the frame-side electrode built-in body 33 and the opening 31b1 of the mounting plate 31b of the case 31, and the stroke of this play n The frame-side electrode built-in body 33 can be moved in the thickness direction Y of the sliding door by an amount.

  When the sliding door is completely closed, as shown in FIG. 2, the sliding door side magnet 26 and the frame side magnet 36 are attracted to each other and the sliding door side electrode 24 and the frame side electrode 34 slide on each other until the sliding door is completely closed. The contacts are polished to move and become energized. Further, when the sliding door is opened, the sliding contact side electrode 24 and the frame side electrode 34 are slid to each other and polished in the section where the sliding side electrode 24 and the frame side electrode 34 are in contact.

  Further, the sliding door-side electrode built-in body 23 and the frame-side electrode built-in body 33 have inclined end surfaces 23c and 33c that face each other when the sliding door is closed from the open state.

The operation of this embodiment will be briefly described below.
When the sliding door a is completely closed, as shown in FIG. 2, the magnetic attractive force between the sliding door side magnet 26 and the corresponding frame side magnet 36, the spring 27 of the sliding door side electrode built-in body 23, and the frame side electrode built-in body 33. The sliding door side electrode built-in body 23 and the frame side electrode built-in body 33 are completely formed by the synergistic action with the biasing force of the spring 37, in particular, by the attraction force between the former sliding door side magnet 26 and the frame side magnet 36. The normal conduction state can be reliably maintained. Therefore, since the sliding door side electrode 24 and the frame side electrode 34 are firmly and reliably in contact, even when the sliding door rattles due to wind or human operation, conduction is normal and contact failure is prevented. The electric lock 1 can be energized from the control panel side lead wire 35 through the sliding door energization device 10 and the sliding door side lead wire 25. Therefore, when a locking signal is sent to the locking lead wire of the control panel side lead wire 35, the lock rod 2 of the electric lock 1 is engaged with the receiving hole 3 of the door frame b and locked. On the other hand, when an unlocking signal is sent to the unlocking lead wire of the control panel side lead wire 35, the lock bar 2 of the electric lock 1 is released from the receiving hole 3 of the door frame b and unlocked.

   As shown in FIG. 2, when the sliding door a is opened from the closed state of the sliding door a, a section where the sliding door side electrode 24 and the frame side electrode 34 are in contact (substantially the sliding door side magnet 26 and the frame side magnet 36 are attracted). In this case, the contact is polished by sliding against each other, so that the deposit on the contact portion can be cleaned. For example, as shown in FIG. 13 and FIG. 14, when the sliding door a is further opened until the electrodes 24 and 34 are not in contact with each other, the electrodes 24 and 34 are in a non-energized state. Can not do it.

   Further, as described above, the sliding door-side electrode built-in body 23 and the frame-side electrode built-in body 33 are completely and reliably held in a normal conductive state by the attractive force between the sliding door-side magnet 26 and the frame-side magnet 36. In addition, since the play m and n are formed between the frame side electrode built-in body 33 and the case 31 in the sliding door opening / closing direction and the sliding door thickness direction, the sliding door side electrode 24 and the frame side electrode 34 are formed. It is possible to prevent the displacement of the contact portion of the contact point with the electrical noise.

   In addition, the electricity supply apparatus 10 for sliding doors can also be attached to the vertical frame a1 of the sliding door a and the vertical frame b1 of the door frame b facing the vertical cage a1.

Further, the shape and size of the sliding door side electrode 24 are not particularly limited, but preferably, the sliding door side electrode 24 has a flat plate shape that is long in the opening / closing direction of the sliding door a and has a large surface contact with the frame side electrode 34 (see FIG. 15). ). For example, as shown in FIG. 16, peaks 241 and valleys 242 are formed on the surface of the sliding door side electrode 24, and the lower surface of the frame side electrode 34 is a flat surface 341 so that the contact portions of both are uniformly polished. Thus, those that further improve the cleaning effect are preferable.
In addition, the shape of the frame side electrode 34 should just be a shape pushed in by sliding of the sliding door side electrode 24. FIG.

  Further, like the play m, n, a play can be provided in the sliding door opening / closing direction X and the sliding door thickness direction Y between the sliding door side electrode built-in body 23 and the case 21.

   An electric circuit and a control circuit inside the electric lock 1 are arbitrary, and for example, an instantaneous electrolytic lock type, a temporary energization locking / unlocking type, an energization unlocking type, and the like can be arbitrarily employed.

  The present invention can be employed as an energizing device for sliding doors such as single sliding doors and sliding doors.
