Description

  The present invention relates to a closing sensor device that picks up a closing signal of an opening / closing body provided in a door frame.

  For example, Patent Document 1 states that “a fixed magnet is provided in a receiving metal fitting on the door frame side, while a latch bolt having a magnet at a tip portion and an elastic body for a latch bolt are provided in a lock box on the door side. "A matter in which a bolt is attracted in accordance with the polarity of the fixed magnet and is engaged with a metal fitting against the spring force of an elastic body" is described. The embodiment described in Patent Document 1 is to eliminate the generation of impact sound such as “Koto” when the door is closed in an opening / closing type opening / closing body.

  Further, in Patent Document 2, “a movable electrode member and a movable electrode member return elastic body are provided in a support box on the door frame side, while a fixed electrode member is provided on the upper lid of the sliding door, and when the sliding door is closed, "Matters to be energized by adsorbing the movable electrode member to the fixed electrode member" are described. The embodiment described in Patent Document 2 is intended for energization.

  As described above, conventionally, in the opening / closing body of a joinery, the matter of providing a fixed magnet or a movable magnet in a case on the door frame side is known. However, neither Patent Document 1 nor Patent Document 2 is “what picks up the closing signal of the opening / closing body corresponding to the dust size”.

In addition, Patent Document 3 describes a matter of providing a drive control unit including one or a plurality of switches in a lock box together with main members constituting an electric lock. The door closing signal of the opening / closing body is not picked up by the contact relationship with the trigger provided on the door frame side. Patent Document 3 describes an example of a mechanism for moving the dead bolt backward.

(C) It is possible to reduce the number of components and to facilitate the combination and manufacture.

  Hereinafter, the best mode (first embodiment) for carrying out the present invention shown in FIGS. 1 to 4 will be described.

(1) Door frame and box-type support member 1 is, for example, a door frame that forms an opening of a building, and 2 is a box-type support member that is mounted in a vertical frame of the door frame 1. It does not matter whether the door frame 1 is for real estate (building) or movable property (ship). In short, the door frame 1 for an opening / closing body (a swing door or a sliding door) may be used.

  First, the box-type support member 2 includes a support box 2A and a front cover 2B that is integrally fixed to the front surface of the support box 2A via an unfixed fastener. Thus, the support box 2A includes a case portion 2a having a recess 3 and upper and lower end plate portions 2b and 2b that are bent outward from the opening end of the case portion 2a.

  Then, horizontal guide means (for example, slit-shaped notches) 4 are respectively formed in a portion near the lower end portion and a portion near the upper end portion of the left and right side walls of the case portion 2a. The slit-shaped notch of the horizontal guide means 4 is an example, and may be a protruding guide rail. Further, a small protrusion-like spring end support portion 5 is provided at the center of the inner surface of the vertical bottom wall at the back of the case portion 2a.

  On the other hand, the front cover 2B joined to the front surfaces of the end plate portions 2b and 2b of the support box 2A has a rectangular opening 7 and attachment holes 8 for fasteners respectively formed at upper and lower ends. Yes. The left / right / up / down width of the opening 7 of the front cover 2B is smaller than the opening width of the recess 3 of the support box 2A, but is set to an appropriate size so that a movable trigger described later can be smoothly projected. ing.

(2) Movable trigger and elastic body Next, the box-type support member 2 incorporates a movable trigger 11 and an elastic body 12 that constantly urges the movable trigger. The movable trigger 11 is a magnetic body (for example, ferrite), and is always urged by the spring force of the elastic body (for example, a coil spring) 12 so that the protruding portion protrudes from the opening of the front cover 2B.

  As shown in FIG. 2, the movable trigger 11 of this embodiment is guided directly (in this embodiment) or indirectly (for example, via a guide rail) to the support box of the support member 2 and the maximum value of dust ( (E.g., 6 mm) having a plate-like flange portion 11a pressed against the inner wall surface of the front cover 2B, and a protruding portion 11b protruding from the opening 7 of the front cover 2B, and the protruding portion 11b is at least a magnetic material. Of course, the flange portion 11a of the movable trigger 11 may also be a magnet.

  Thus, upper and lower engagement protrusions 13 that engage with the horizontal guide means 4 of the support box 2A are provided on the left and right side walls of the flange portion 11a. In addition, an unnumbered spring end support portion (for example, a recess) is formed in the center of the back surface of the movable trigger 11. In addition, the form of the protrusion part 11b of the movable trigger 11 is formed in planar fingertip shape in consideration of the case where the opening / closing body is an open door.

(3) Opening / closing body side 15 is an opening / closing body (a hinged door or a sliding door) provided at the opening of the door frame 1. When the opening / closing body 15 is an open door, the base end is attached to the vertical frame of the door frame via upper and lower hinges, as is well known. Further, when the opening / closing body 15 is a sliding door, the door tip can contact the front surface of the front cover 2 </ b> B of the support member 2. For example, there are two types of electric locks for confirmation of going out that are manufactured and sold by the applicant: an open door type and a sliding door type. The open door type is several millimeters (for example, 3 mm, 4 mm, 5 mm) between the end surface of the free end of the opening / closing body 15 and the vertical frame of the door frame 1 (or the front surface of the front cover 2B of the support member 2), depending on the attachment. , 6 mm, etc.). Moreover, in the case of a sliding door type, depending on the engagement state of the sickle piece, dust within 6 mm is similarly generated between the door tip and the door frame 1.

  FIG. 1 shows a case where the counterpart opening / closing body 15 of the box-type support member 2 is a sliding door, and the lock is an example of an electric lock. The electric lock shown in FIG. 1 includes a detection unit 17 and a drive control unit 18 that acquires a signal from the detection unit 17 in a lock box 16. The detection means 17 is fixedly disposed via a support piece 20 on the back side of the front 19 constituting the lock box 16 so that the magnetic force of the movable trigger 11 can be detected when the door is closed. As an example of the detecting means 17, a Hall IC is employed. Of course, the detection means 17 is not limited to this, and a reed switch or other non-contact type magnetic sensitive sensor can be used.

  The detection means 17 is electrically connected to a drive control unit 18 having a printed board via a wiring 21. The drive control unit 18 gives a drive signal (voltage application) to a drive source (for example, a micro motor) 22, and the drive force of the drive source 22 is transmitted via a power transmission means (for example, a gear, a clutch mechanism, a drive rod) 23. Reported to Dharma 24. As is well known, when the dharma 24 rotates by a required amount in the clockwise or counterclockwise direction, for example, a dead bolt 26 having a sickle piece 25 moves forward and backward. And the sickle piece 25 interlock | cooperated with the deadbolt 26 engages with the strike of the metal fitting 27 provided in the door frame 1 at the time of locking.

(4) Operation FIG. 3 corresponds to the case where the detection means 17 provided at the door tip of the opening / closing body 1 (for example, the back side of the front 19) has a large dust size (for example, 6 mm), while FIG. Reference numeral 17 denotes a case corresponding to a case where the dust size is small (for example, 1 mm). As shown in FIG. 3, when the dust size is large when the door is closed, the movable trigger 11 has a flange portion corresponding to the dust size of the opening / closing body 15 by the elastic force of the elastic body 12 in the support box 2 </ b> A. Advance to a position where it presses against the inner wall of the front cover. Therefore, the protruding portion 11b of the movable trigger 11 protrudes from the opening 7 of the front cover 2B. At this time, even when the dust size is larger than the maximum value (for example, 6 mm) (for example, 8 mm), since the magnetic field centered on the protruding portion 11 b is formed, the detection means 17 is configured to have the magnetic force of the movable trigger 11. Can be reliably detected.

  Further, as shown in FIG. 4, when the size of the chile is small when the door is closed, the movable trigger 11 is pushed by the front surface of the front 19 of the lock box 16 on the front end surface of the protrusion 11 b, so that the opening / closing body 15. Corresponding to the above-mentioned dust size, it is displaced backward against the elastic force of the elastic body 12 in the support box 2A. In both the former and the latter cases, the detection means 17 senses the magnetic force emitted from the protruding portion 11b (so-called non-contact type detection means). Then, the signal picked up by the detection means 17 is sent to the drive control unit 18 as a closing signal of the opening / closing body 1.

  In the first example shown in the embodiment of the invention, a small opening may be formed at an appropriate part of the front 19 so that the detection means 17 is easily subjected to the magnetic field of the protruding portion 11b of the movable trigger 11. . The horizontal guide means 4 provided on the support member 2 is a slit-shaped notch 4, but may be a pair of left and right guide shafts (rod-like bodies) penetrating the left and right portions of the flange portion 11 a of the movable trigger 11, for example. . Further, although not particularly shown, the horizontal guide means 4 may be a frame-shaped base having a single or a plurality of cylindrical guide columns.

  By the way, in the first embodiment, the detecting means 17 for detecting the magnetic force of the protruding portion 11b of the movable trigger 11 is provided in the lock box 16, but may be provided in addition to the lock box 16 as shown in FIG. Here, the door closing sensor device shown in FIG. 5 is used as a second embodiment for the sake of convenience, and the same reference numerals as those in the first embodiment are attached to omit redundant description.

  Also in the second embodiment, similarly to the first embodiment, the box-type support member 2 is fixedly attached to the horizontal recesses such as the upper and lower portions of the door frame 1 and the vicinity of the lock box. A magnetic movable trigger 11 and an elastic body 12 that constantly urges the protruding portion 11b of the movable trigger to protrude from the opening 7 of the front cover 2B are provided.

  On the other hand, the opening / closing body 15 is, for example, a sliding door, and a detecting means 17 for detecting the magnetic force of the protruding portion 11b of the movable trigger 11 is provided in the vicinity of the lock box at the door end of the sliding door 15 (Example).

  Therefore, the detection means 17 on the opening / closing body 15 side is arranged at an appropriate portion (upper part, lower part, near the lock box, near the lock box of the sliding door 15 so as to correspond to the mounting position of the box-type support member 2 of the door frame 1. Etc.). In addition, the detection means 17 of 2nd Example is electrically connected through the wiring 21 to the drive control part 18 housed in the lock box 16, for example.

  Even in such a configuration, the movable trigger 11 is similarly retracted into the box-type support member 2 when the door is closed, corresponding to the dust size of the opening / closing body 15 and resisting the elastic force of the elastic body 12. It is.

  Since the present invention is a “door closing sensor device”, the door closing confirmation system including the main part of the present invention as it is and taking into account means (apparatus that appeals to sight and hearing) is equivalent to a use invention. It can be said.

  The present invention is mainly used in industries such as locks and joinery.
