Further, the thickness of the holder 4 in the door opening / closing direction can be made very thin, and if a safety sensor is attached to the door-to-door side, a passerby is not conscious and the aesthetics of the door are not impaired in terms of design.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 4 shown corresponding to FIG. 3 is an example in which the present invention is applied to a wooden door panel or a tempered glass door panel, and devices having the same reference numerals perform the same functions and have a C-shaped mounting member 3. Bolts 30 (FIG. 4C) or nuts 40 (D) as fastening members are fixed to a plurality of locations in advance by spot welding or the like, and the spacer member 26 is hollow through the back surface of the holder 4 A hole portion of the fixing portion 27 is formed. A head amplifier 7 is embedded on the upper end side of the holder 4 and is connected to the parallel electrode plate of each sensing portion 5 i (i = a to n) by a coaxial cable 24.

  The work procedure for attaching the safety sensor to the door panel in this configuration will be described. First, a) the cover on the side of the joint is removed, and the mounting member 3 having a C-shaped cross section to which the bolt 30 or the nut 40 as a fastening member is fixed is provided. The panel 2 is fixed to the frame 28 on the door-to-door side with a male screw 29. b) Applying an adhesive to the panel contact surface of the holder 4 in which the sensing unit 5 is inserted in advance and the hole is formed in the hollow fixing unit 27, and then the holder 4 is moved horizontally in the opening and closing direction of the panel, The bolt 30 is inserted into the hole of the hollow fixing portion 27. At this time, in order to stabilize the fixing of the holder 4, it is preferable to insert a spacer 31 on the outer periphery of the bolt 30 according to the depth of the mounting member 3, and a reinforcing plate 32 is provided outside the back surface of the holder 4. It is preferable to attach it. Further, when the nut 40 is fixed to the mounting member 3, the length thereof is equal to the depth of the mounting member 3, and the hole portion of the hollow fixing portion 27 and the nut 40 are aligned and matched. 4) In the case of FIG. 4C, a washer 34 and a nut 36 as a fastening member are screwed onto the bolt 30 to fix the holder 4 to the mounting member 3. In the case of FIG. 4D, the holder 4 is fixed to the mounting member 3 by a washer 42 and a screw 44 as a fastening member. d) Thereafter, the surface of the hollow fixing portion 27 is planted with a sealing material, and predetermined wiring is performed.

  The mounting operation of the safety sensor to the automatic door panel is very light with both the mounting member 3 and the holder 4 within several kilograms, so that one worker can perform it alone, and the working time can be as short as about 1 hour. It is safe because there is no work to move heavy objects. Further, the length of the holder 4 in the opening / closing direction can be very thin, around 20 mm. If a safety sensor is attached to the door-to-door side, the passerby is not conscious and the door aesthetics are not impaired.

  FIG. 5 corresponding to FIG. 4 is another embodiment of the present invention, and is a case where the mounting member 3 such as a coffin door or a Senage door is preinstalled on the door panel 2 side, FIG. 5A is a perspective view of a sandwiching and fastening member 50i that can be attached to and detached from the holder 4. A hollow female threaded portion 53 is formed in a substantially rectangular sandwiching plate 50 having a length H and a width W. A cylindrical hollow female screw member 51 is fixed by welding or the like, and a flat portion 52 that is cut into a flat shape is provided on the tip side thereof in order to determine the rotation angle of the sandwich plate 50.

  Next, a safety sensor mounting operation using the clamping and fastening member 50i (i = a to n) will be described. f) First, remove the cover on the blind side so that the wiring work can be performed. In addition, since the attachment member 3 is provided in the panel 2 by the coffin door etc., the fixing operation | work of the attachment member 3 is unnecessary. g) Next, as shown in FIG. 5 (B), a clamping and fastening member 50i is inserted into the holder 4 from the back surface, and temporarily fixed by a clip 56i from the front surface side at a rotational position where the longitudinal direction becomes vertical. And fix. In addition, since the width W of the sandwiching plate 50 is inserted into the C-shaped gap of the mounting member 3, it is necessary to be narrower than this, and the length H of the sandwiching plate 50 is equal to the lateral width of the groove of the mounting member 3. A slightly longer one is preferable because it does not idle during fastening, which will be described later, and can be securely fixed to the mounting member 3. h) After that, the holder 4 is stood in the vertical direction, moved horizontally in the panel opening / closing direction, the back surface (bottom part) of the holder 4 is brought into contact with the mounting member 3, and the sandwiching plate 50 is placed in the C-shaped gap of the mounting member 3. Insert into. i) Next, the clip 56 i is slightly moved to the tip side, the tip of the female screw portion 53 is sandwiched again, and the clamping plate 50 is pushed into the groove of the C-shaped mounting member 3. Subsequently, the clip 56i is rotated in a state where the sandwiching plate 50 is pushed into the groove, and the sandwiching plate 50 and the attachment member 3 are held as shown in FIGS. 5 (E) and 5 (F). . j) Next, after removing the clip 56i and inserting the washer 54 and the spacer member 58i, the holder 4 and the three attachment portions are sandwiched together with the reinforcing plate 32 coated with adhesive on the back surface by the bolt 59 as a fastening member. Fasten and fix with pinching plate 50. k) Thereafter, the surface of the hollow fixing portion 27 is implanted with a sealing material, and after performing predetermined wiring, a cover on the blind side is applied.

  In such safety sensor mounting work on the automatic door panel, the holder 4 is very light, within a few kg, so that even one worker can perform it, and there is no need to work on the mounting member 3 such as bolts / nuts. The working time is less than 30 minutes, which is short, and it is safe because there is no heavy moving work. In the above description, the hollow fixing portion 27 is provided in the holder 4. However, if the structure of the holder is such that the lid or the like can be opened / closed or attached / detached, it is not necessary to plant the sealing material on the hollow fixing portion 27. The coaxial cable 24 and the sensing plates 20a and 20b are not shown.

  FIG. 6 corresponding to FIG. 5 shows another embodiment of the present invention, and devices having the same reference numerals perform the same functions, and spatial directivity as a non-contact proximity sensor. Instead of the high-frequency proximity sensor 5i without the optical reflective proximity sensors 70 and 70a having spatial directivity, the optical reflective proximity sensor 70 is arranged on the panel side-by-side. In addition to functioning as a safety sensor, an optical reflective proximity sensor 70 is also provided in the entrance / exit direction of the automatic door so that this sensor can also function as an activation sensor.

  Accordingly, a plurality of optical reflective proximity sensors 70 each having directivity in the three directions of the automatic door entrance direction, the exit direction, and the door-to-door direction are distributed in the hollow portion of the holder 4. However, on the side surface of the holder 4 on which the optical sensor 70 is disposed, window portions 48 are formed at predetermined positions in order to transmit the projection light and the reflected light.

  The attaching operation of the holder 4 to the attaching member 3 is the same as the above steps f) to j). Further, in FIG. 6D, the light source means 72 is arranged so that light is projected in the vertical direction, and the projected light is bent in a substantially horizontal direction by a reflecting member 73 such as a mirror, and the light is emitted from the window 74 to the outside. Then, the reflected light is input through the window 74, bent again in the vertical direction by the reflecting member 73 and input to the light receiving means 75, and the output is subjected to arithmetic processing by the detecting means 76, depending on the amount of reflected light. An optical system for determining whether or not a person is present is shown.

  On the other hand, in FIG. 6E, light from the light source means 72 is projected in a substantially horizontal direction and output to the outside through an imaging member 77 such as a lens, and the reflected light is transmitted through the imaging member 77. An optical system is shown in which the light input means 75 is input and the output is processed by the detection means 76. The projection optical system and the incident optical system are separated by a light shielding means 78.

  Any of the optical reflective proximity sensors can be embedded in the holder 4, and in particular, the optical system as shown in FIG. 6D has a very thin structure with a door opening / closing direction length of 10 mm or less. However, since the angle adjustment of the projection light and reflected light of the optical system can be freely changed and adjusted, it is very preferable as a safety sensor / safety / startup sensor attached to the door-to-door side of the automatic door panel. In addition, when using an optical reflective proximity sensor as a safety sensor, when light is projected in the horizontal direction, very strong reflected light may return from the opposing door panel or metal surface on the building side due to specular reflection or the like. Therefore, it is preferable to project light with an inclination of several degrees with respect to the horizontal direction.

A cylindrical hollow female screw member 51 having a hole formed therein is fixed, and an elastic member 38 such as a winding spring is wound around the inner side of the holder 4 at the tip side thereof, so that the elastic member 38 is prevented from falling off. A wide spacer member 58 is screwed to the front end of the holder, and a rotation groove 39 of the sandwiching plate 50 is recessed. FIG. 7B shows the entire holder 4 before being attached to the attachment member 3. Sections are shown, and devices with the same numbers have the same functions With play, the hollow fixed portion 60 for fixing the holder 4 to the hollow female screw member 51 is adapted to be disposed outside of the spacer member 58 with the hole 62.

  Next, a safety sensor mounting operation using the clamping and fastening member 50i will be described. Assuming that the mounting member 3 is disposed and fixed in advance on the door panel 2 side, such as a coffin door or a Senage door, first, m) First, the holder 4 having a cross section as shown in FIG. Assuming that they are integrated and assembled at a different location, after applying an adhesive to the contact surface of the holder 4 with the mounting member 3, the holder 4 is set up in the vertical direction and remains in the opening and closing direction of the panel. The holder 4 is moved in parallel, the back side of the holder 4 is brought into contact with the mounting member 3, and the sandwiching plate 50 is inserted into the C-shaped gap portion of the mounting member 3 with the longitudinal direction being vertical. n) Next, by using the groove 39 with a driver or the like, the sandwiching plate 50 is pushed into the mounting member 3 and then rotated to rotate the sandwiching plate 50 and the mounting member 3 as shown in FIG. Hold on. o) Subsequently, a bolt 59 as a fastening member is inserted into the hollow female screw portion 53 and tightened, and the holder 4 and the mounting member 3 are fastened and fixed while being sandwiched between the sandwiching plates 50.
