Description

  The present invention relates to a decorative cover that covers a gap between two security sensors in a security sensor device in which a pair of security sensors are supported on both sides of a support pole.

  In an active sensor device used in a warning area with a relatively long warning distance, a plurality of sensor sets, for example two, may be arranged in series. In that case, in general, a security sensor including a projector and / or a light receiver is attached to each of the support poles at both ends of the warning area, and another pair for transmitting / receiving a detection line to / from the security sensor to the central support pole. Install security sensors in a back-to-back arrangement. In such an arrangement, two back-to-back crime prevention systems aim to improve the aesthetics by hiding the support poles between the security sensors and to conceal the wiring connected to both security sensors so that they are not mischievous. It is known to attach a decorative cover that covers the gap between the sensors (see Non-Patent Document 1).

  The decorative cover is attached by the following construction procedure. That is, as shown in FIG. 7, first, the mounting plate 51 of the first security sensor (for example, the light receiver) 50 </ b> A is a half in which the screw body 59 inserted through the insertion hole 51 a is applied to the support pole 54. The circular mounting bracket 58A is fixed to the support pole 54 by screwing into the screw holes 58a at both ends. Next, the sensor body 52 of the first security sensor 50A is attached to the mounting plate 51 by fastening a screw body (not shown), and the sensor body 53 is put on the sensor body 52 and the screw body (not shown) is attached. By fastening, the first security sensor 50 </ b> A is supported by the support pole 54. Subsequently, as shown in FIG. 8, the mounting plate 60 of the second security sensor (for example, the light receiver) 50B is screwed into the screw holes 58a at both ends of the mounting bracket 58B in the same manner as described above. It is fixed to the support pole 54. The mounting plate 60 is provided with four mounting projections 61 projecting sideways having screw holes 61a for mounting the decorative cover.

  Next, the decorative cover 62 is attached to the attachment plate 60. The decorative cover 62 is formed by bending a strip-shaped sheet metal, and a pair of side walls 62a and 62b facing each other, an upper wall 62c connecting the upper ends of the side walls 62a and 62b, and a relative relationship between the side walls 62a and 62b. There are two attachment pieces 62d provided on the inner surface facing each other, and insertion holes 62e formed in each attachment piece 62d. The lower ends of the side walls 62a and 62b are open. The decorative cover 62 is inserted into the insertion holes 62 e of the decorative cover 62 and screwed into the screw holes 61 a of the mounting protrusions 61 of the mounting plate 60, so that the decorative cover 62 is attached to the mounting plate 60 fixed to the support pole 54. It is attached. Finally, the second security sensor 50B is attached in the same procedure as the first security sensor 50A described above. As a result, the decorative cover 62 has both side walls 62a and 62b covering the gap between the security sensors 50A and 50B from the side, and the upper wall 62c is above the gap between the security sensors and the support pole 54. The arrangement covers the end face.

  However, the decorative cover 62 has various problems. First, if there is a request to add a cosmetic cover to an existing security sensor device for the purpose of improving aesthetics or preventing mischief of wiring, one of the security sensors, for example, After removing the second security sensor 50B once, a mounting plate 60 having a screw hole 61a for mounting the decorative cover is mounted on the mounting bracket 58B, a decorative cover 62 is mounted on the mounting plate 60, and the second mounting plate 60 is attached to the second mounting plate 60. It is necessary to reattach the security sensor 50B. Since the security sensor 50B is once removed from the support pole 54, it is necessary to redo the adjustment of the optical axis with the corresponding security sensor (for example, a projector). Therefore, when the decorative cover 62 is additionally attached to the existing security sensor device, a considerable work burden is imposed on the installer.

  Second, the decorative cover 62 is attached to one of the security sensors, in this example, the mounting plate 60 of the second security sensor 50B. It is always attached to the security sensor 50B at a fixed relative position. Accordingly, when the security sensor device is supported by the support pole 54 having a small pole outer diameter, the distance (gap) between the security sensors 50A and 50B becomes small, so the decorative cover 62 is the first crime prevention cover 62. It protrudes more than necessary on the sensor 50A side, greatly overlaps the side of the first security sensor 50A, blocks a part of the detection line to the optical system of the first security sensor 50A, or protrudes on the decorative cover 62. The reflected light may enter the optical system and the first security sensor 50A may malfunction. Therefore, the width W of the side walls 62a and 62b of the decorative cover 62 cannot be set larger than necessary.

  On the other hand, when the security sensor device is supported by the support pole 54 having a large pole outer diameter, the distance (gap) between the security sensors 50A and 50B becomes large. A part on the security sensor 50A side cannot be concealed by the decorative cover 62 and is exposed to the outside, leading to a decrease in aesthetic appearance. Therefore, the width W of the side walls 62a and 62b of the decorative cover 62 cannot be set smaller than necessary. As described above, the width W of the side walls 62a and 62b of the decorative cover 62 needs to be set within a predetermined range. Accordingly, the support pole 54 applicable to the decorative cover 62 has a pole outer diameter within a narrow range. Limited to what you have.

  Thirdly, the decorative cover 62 is formed by bending a strip-shaped sheet metal and connecting one end portions of both side walls 62a and 62b with the upper wall 62c. The upper wall 62c is a simple rectangular shape without a pole insertion hole. Since it is a shape, it can be applied only to applications for covering the security sensor device supported by the upper end of the support pole 54. That is, it cannot be attached to a security sensor device that is supported by an intermediate portion other than the upper end portion of the support pole 54, which requires the support pole 54 to be inserted through the decorative cover 62.

  An object of the present invention is to provide a decorative cover that can be easily attached to an existing sensor device for crime prevention in an arrangement that covers it without removing it, and that can cope with various outer diameters of poles. Another object of the present invention is applicable to both a security sensor device attached to a support pole having a wide range of pole outer diameters and a security sensor device supported at an arbitrary height position of the support pole. It is to provide a cosmetic cover.

  In order to achieve the above object, the cosmetic cover of the security sensor device according to the present invention is a cosmetic cover that covers a gap between the security sensors in a support structure in which the security sensor is supported on one side portion and the other side portion of a support pole. A cover having a pair of cover pieces that are divided into two in the longitudinal direction of the support pole, each of the cover pieces having a pair of front and rear side walls and a connection wall that connects one end of each side wall. And the other opposing ends of the pair of cover pieces are connected by a detachable connector.

  In the decorative cover of this security sensor device, a pair of cover pieces are inserted along the longitudinal direction of the support pole so as to cover the gap between the security sensors, and the other opposite ends of each are connected by a connector. Then, the both side walls and connection walls of each of the pair of cover pieces are attached so as to cover the front and rear gaps between both security sensors and both ends. Thus, unlike a conventional decorative cover that is fixedly attached to a part of the security sensor device, this decorative cover is not provided with any direct fixing means for the security sensor device, and a pair of covers are provided. It is installed in an arrangement that covers both security sensors by connecting them together. Therefore, when a decorative cover is additionally attached to the existing security sensor device on the support pole, it is not necessary to remove a part of the security sensor device from the support pole, and the other ends of both cover pieces are attached and detached. It can be easily attached to the security sensor device by a simple operation of simply connecting with a flexible connector. Moreover, since the decorative cover is not fixedly attached to the security sensor, the gap can be appropriately covered by matching the center of the decorative cover to the middle position of the gap between the security sensors. Therefore, unlike the case where a decorative cover is attached to one security sensor, the other security sensor does not protrude more than necessary, and a part of the other security sensor on the support pole is not exposed. Therefore, this decorative cover can be applied to the security sensor device supported by the support pole having a wide range of pole outer diameters without any trouble, and improves the beauty of the security sensor device.

  In the present invention, it is preferable that each cover piece is provided with a positioning mechanism that presses against both security sensors with a spring force to position the cover piece in the middle between both security sensors. As a result, the decorative cover is positioned so as to be automatically positioned in the middle of the gap corresponding to the gap between both sensors depending on the pole outer diameter of the support pole on which both sensors are supported. The Thereby, it is possible to automatically and appropriately cope with a wide range of pole outer diameters.

  In the configuration having a positioning mechanism, each positioning mechanism includes a first contact that contacts one security sensor, a second contact that contacts the other security sensor, and a security sensor that corresponds to each contact. It is preferable to have a spring body that is advanced toward the front and a locked portion that is locked to a locking portion provided in each contact at an advance limit position and positions each contact at the advance limit. As a result, even if the size of the gap between the two sensors varies depending on the pole outer diameter of the support pole on which both sensors are supported, both cover pieces point each contact toward the corresponding security sensor. The two spring bodies to be advanced are moved to a position where the spring forces are balanced, and are automatically positioned in the middle of the gap between the two sensors.

  In the present invention, the support pole extends in the vertical direction, the decorative cover has an upper first cover piece and a lower second cover piece, and the second cover piece is lateral to the support pole. It is preferable to have an engagement hole to be fitted from the outside. As a result, the second cover piece is moved upward while sliding on the support pole in a state where the support pole is fitted from the side into the engagement hole, and both are connected to the first cover piece. Since it can be set as the arrangement | positioning which covers the clearance gap between sensors, a decorative cover can be attached with easy operation with respect to both existing sensors in a support pole.

  In the present invention, it is preferable that at least the connection wall of the first cover piece has a knockout plate for selectively forming an insertion hole through which the support pole is inserted. As a result, if the insertion hole for cutting the knockout plate and inserting the support pole is formed in the connection wall of the first cover piece, the first cover piece is supported at any intermediate position other than the upper end of the support pole. It can be attached to both the sensors in an arrangement that covers the gap between them.

  In the configuration in which at least the connection wall of the first cover piece has a knockout plate, the connection wall of the lower second cover piece also has the knockout plate, and the connection wall of each cover piece further includes A wall main body integrally formed on both side walls, and a separation wall that is detachably attached to the wall main body and forms an insertion hole for the support pole between the wall main body and the wall main body. It is preferable to have. Thus, since both the first and second cover pieces have the knockout plate and the wall body and the separation wall, the same shape can be shared. The cost of the mold can be reduced, and the two cover pieces can be reduced in shape by dividing the decorative cover into two at the intermediate position, so that the packaging shape can be reduced to reduce the transportation cost. it can.

  According to the decorative cover of the security sensor device of the present invention, a pair of cover pieces divided into two in the longitudinal direction of the support pole are arranged so as to cover the gap between the security sensors supported by the support pole, By connecting each other opposite ends with a connecting tool, it can be attached in an arrangement covering the front and rear and both gaps between both security sensors, so that it is fixedly attached to a part of the security sensor device. Unlike the decorative cover, it is attached in such a manner as to cover the security sensors by connecting a pair of covers to each other without using any direct fixing means for the security sensor device. Therefore, when the decorative cover is additionally attached to the existing security sensor device on the support pole, there is no need to remove a part of the security sensor device from the support pole, and the other ends of both cover pieces can be detachably connected. The decorative cover can be easily attached to the security sensor device by a simple operation of simply connecting with a tool. Therefore, when a decorative cover is additionally attached to the existing security sensor device on the support pole, it is not necessary to remove a part of the security sensor device from the support pole, and the other ends of both cover pieces are attached and detached. It can be easily attached to the security sensor device by a simple operation of simply connecting with a flexible connector. In addition, since the decorative cover is not fixedly attached to the security sensor, the gap can be appropriately covered by matching the center of the decorative cover to the middle of the gap between both security sensors, so a wide range of poles The outer diameter can be accommodated, and the aesthetic appearance of the security sensor device is improved.

In FIG. 1, the same or equivalent to those shown in FIGS. A reference numeral is attached, and a duplicate description is omitted. The decorative cover 1 in FIG. 1 is attached so as to cover a gap between two security sensors 50A and 50B supported on one side and the other side of a support pole 54 erected on the ground. The support pole 54 has a pair of cover pieces 2 and 3 that are divided into two in the longitudinal direction (vertical direction in this embodiment). In this embodiment, the upper first cover piece 2 and the lower second cover piece 3 have the same shape, and therefore, each cover piece 2, 3 is obtained by dividing the decorative cover 1 into two in the middle in the longitudinal direction. It becomes. The opposite end portions of the cover pieces 2 and 3 are connected to each other by a detachable connecting tool 4 to form the decorative cover 1.

  FIG. 2 shows an exploded perspective view of FIG. The first and second security sensors 50A and 50B are supported in a back-to-back arrangement on one side and the other side of the support pole 54 in the same procedure as described in FIG. In other words, the mounting plate 51 of the first security sensor 50A is attached to the support pole 54 with the screw body 59 inserted through the insertion hole 51a in a semicircular shape. Are fixed to the support poles 54 by being screwed into the screw holes 58a at both ends. Next, the sensor main body 52 of the first security sensor 50A is attached to the mounting plate 51 by fastening a screw body (not shown), and the sensor body 53 and the mounting plate 51 are covered with the sensor cover 53 and the screw body (FIG. 1st security sensor 50A is supported by support pole 54 by fastening (not shown). The second security sensor 50B is also attached to the support pole 54 in the same procedure. The wirings of both security sensors 50 </ b> A and 50 </ b> B are inserted into through holes (not shown) provided in the support pole 54 and pass through the hollow portion of the support pole 54, for example.

  The first and second security sensors 50A and 50B are generally both light projectors or both light receivers. On the other hand, one light receiver or light projector is disposed on each of the other two support poles so as to face the security sensors 50A and 50B. However, one of the back-to-back security sensors 50A and 50B may be a projector, and the other may be a light receiver. In the case of a projector, the sensor body 52 includes a light projecting element that emits a detection line such as infrared rays, a drive circuit for the light projecting element, a lens for projecting the detection line, and the like. In the case of a light receiver, the sensor body 52 includes a light receiving element that receives the detection line, a light receiving circuit that processes an electrical signal from the light receiving element, a light receiving lens for the detection line, and the like. An intruder is detected by blocking the detection line projected from the projector to the light receiver.

  The first and second cover pieces 2, 3 of the decorative cover 1 are a pair of front and rear first and second side walls 8, 9 that face each other, and a connection wall 10 that connects one end portions of both side walls 8, 9 to each other. And have. The cover pieces 2 and 3 having the same shape as each other are arranged so as to be opposed to each other by turning the other 180 ° and upside down. Accordingly, the cover pieces 2 and 3 are connected to each other in such a manner that the first side walls 8 and the second side walls 9 face each other. On the first side wall 8 of each cover piece 2, 3, a connecting piece 11 is integrally projected from the central part in the left-right direction at the other end of the cover piece 2, and the connecting piece 11 is inward from the inner surface thereof. A cylindrical connecting boss 12 projecting in the direction is formed. In the second side wall 9, an insertion hole 13 of the connector 4 (FIG. 1) is drilled at a location near the other end. The second side wall 9 is formed with a plurality of guide protrusions 14 at both side positions of the insertion hole 13 on the inner surface thereof, which will be described later in detail.

  FIG. 3 shows an exploded perspective view of the decorative cover 1. At both side positions of the insertion hole 13 on the inner surface of the second side wall, L-shaped holding protrusions 14 that allow the connection piece 11 to pass in the vertical direction (longitudinal direction of the support pole 54) are located at both side positions of the insertion hole 13. Two are formed. Each holding projection piece 14 engages with the left and right sides of the connection piece 11 to prevent the relative inclination of the cover pieces 2 and 3, and the other end face of each side wall 8 and 9 of the cover pieces 2 and 3. Are positioned so that the connecting boss 12 matches the insertion hole 13. By inserting the connector 4 into the insertion hole 13 in a state of being matched with each other and screwing it into the connecting boss 12, both guide pieces 2 and 3 are connected to form the decorative cover 1. In this embodiment, a tapping screw that is screwed into the connecting boss 12 is used as the connecting tool 4.

  The connection wall 10 of each cover piece 2, 3 has a wall body 10 a and a separation wall 18. The wall body 10a is integrally formed with the pair of side walls 8 and 9 of the cover pieces 2 and 3, and connects the side walls 8 and 9. The separation wall 18 is formed separately from the cover pieces 2 and 3 and is detachably attached to the cover pieces 2 and 3. The connection wall 10 can be changed to a shape in which two types of support poles 54 having different pole outer diameters can be selectively inserted. That is, the wall main body 10a is formed with a semicircular engagement hole 10b that fits into the support pole 54 having a small pole outer diameter from the side, and has a semicircular shape having a larger diameter than the engagement hole 10b. The knockout portion 10c formed in a thin wall is provided in a concentric arrangement with the engagement hole 10b. Therefore, if the inner portion of the wall body 10a is cut off along the knockout portion 10c and the inner portion thereof is excised, the engagement hole 10b of the wall body 10a is fitted into the support pole 54 having a large pole outer diameter from the side (in the radial direction). A semicircular shape having a large inner diameter that can be formed.

  On the other hand, the separation wall 18 is attached to the wall body 10a as clearly shown for the lower second cover piece 3. That is, when the separation wall 18 is disposed so as to constitute a part of the connection wall 10 with respect to the wall main body 10a, the attachment portion 21 formed on the inner surface thereof is aligned with the support boss portion 10d of the wall main body 10a. In this state, the tapping screw 19, which is an example of a fixture, is screwed into the support boss portion 10 d via the attachment portion 21, thereby being connected to the wall body 10 a to form the connection wall 10. As shown for the upper first cover piece 2, the separation wall 18 has a circular knock-at plate 20 having the same diameter as the semicircular engagement hole 10 b of the wall body 10. The at-plate 20 is connected to the separation wall 18 via a small-diameter knockout portion 22 having one half protruding from the separation wall 18 and the other circular portion formed in a thin semicircular shape. Further, a large-diameter knockout portion 24 having a thin semicircular shape having the same diameter as that of the knockout portion 10c of the wall body 10a is formed on the separation wall 18 in a concentric arrangement with respect to the small-diameter knockout portion 22. .

  When the pair of security sensors 50A and 50B are supported by the upper end of the support pole 54, the connection wall 10 of the upper first cover piece 2 is connected to the wall body 10a as it is, so that the knockout plate The half of the 20 projecting in a semicircular shape is fitted into the engagement hole 10b of the wall body 10a to form a rectangular flat plate, and this rectangular flat connecting wall 10 is formed on the upper end surface of the support pole 54 (FIG. 2). Cover the whole.

  At this time, the connection wall 10 of the lower second cover piece 3 is formed as follows. That is, when the support pole 54 has a small outer diameter, the second cover piece is fitted into the engagement hole 10b of the wall body 10a of the second cover piece 3 from the side. 3 is applied to the support pole 54. On the other hand, the knockout plate 20 of the separation wall 18 is cut along the small diameter knockout portion 22, and the separation wall 18 is connected to the wall body 10 a by the tapping screw 19. As a result, the connection wall 10 of the lower second cover piece 3 has an inner peripheral surface 22a that matches the engagement hole 10b of the wall body 10 and the outer diameter surface of the small-diameter knockout portion 22 of the separation wall 18 as shown in FIG. Thus, an insertion hole 23A is formed through which the support pole 54 having a small pole outer diameter is inserted.

  Furthermore, when the pole outer diameter of the support pole 54 is large, the wall main body 10a of the second cover piece 3 is cut along the large-diameter knockout portion 10c to cut off the outer portion of the knockout portion 10c, thereby engaging the The hole 10 has a large inner diameter. In accordance with this, the knockout plate 20 of the separation wall 18 is cut along the large diameter knockout portion 24. As a result, the connecting wall 10 of the second cover piece 3 has a pole formed by an engagement hole having a large diameter of the wall body 10 and an inner peripheral surface matching the outer diameter surface of the large-diameter knockout portion 24 of the separation wall 18. An insertion hole 23B through which the support pole 54 having a large outer diameter is inserted is formed.

  Further, when the pair of security sensors 50A and 50B are supported at the lower intermediate position from the upper end of the support pole 54 (in the case of FIG. 2), the upper first cover piece 2 also has the second cover piece 3 Similarly to the case, the support pole 54 having a small or large pole outer diameter is selected by selecting the engagement hole 10b or the knockout portion 10c of the wall body 10a and the small diameter knockout portion 22 or the large diameter knockout portion 24 of the separation wall 18. The insertion hole 23A or 23B is formed in the first cover piece 2, and the support pole 54 is inserted through the insertion hole 23A or 23B.

  As described above, the connection wall 10 of the cover pieces 2 and 3 has the wall body 10a formed integrally with the side walls 8 and 9, and the separation wall 18 having the knockout plate 20 and detachably attached to the wall body 10a. By attaching a separation wall 18 of which the presence or absence and the size of the knockout plate 20 are selected to the wall body 10a, the upper first cover piece 2 and the lower second cover piece 3 have the same shape. Can be shared.

  Since the cover pieces 2 and 3 are not fixed at all to the security sensors 50A and 50B, only the distance corresponding to the gap (S in FIG. 6) between the support pole 54 and the insertion holes 23A and 23B of the cover pieces 2 and 3 is provided. The side walls 8 and 9 move in the width direction (left and right direction). Therefore, a positioning mechanism 28 having the same configuration is provided in the vicinity of the connecting wall 10 on the opposing inner surfaces of the side walls 8 and 9 of the cover pieces 2 and 3. This positioning mechanism 28 is accommodated in a mechanism accommodating portion 29 formed on the inner surface of the side walls 8 and 9 in such a manner that a pair of contacts 30A and 30B protrudes from both side openings, and each contact 30A and 30B is accommodated. The cover pieces 2 and 3 function to be positioned at an intermediate position between the security sensors 50A and 50B by being pressed against the back surfaces of the corresponding security sensors 50A and 50B with the same spring force.

  Next, details of the positioning mechanism 28 will be described with reference to FIGS. FIG. 4 shows a relative arrangement when the pair of contacts 30A, 30BA, 30B and the spring body 31 are housed inside the mechanism housing portion 29. As the spring body 31, the same coil spring is used in this embodiment. Therefore, the spring force of the pair of spring bodies 31, 31 is the same. On the other hand, the pair of contacts 30A and 30B are made of resin having the same shape, and the other is inverted with respect to the other, that is, rotated by 180 ° around the axis C1 along the moving direction of the contacts 30A and 30B. With this arrangement, they are accommodated in the mechanism accommodating portion 29 (FIG. 3) opposite to each other. The contacts 30A and 30B have a substantially triangular outer shape, and a contact end portion 30a is provided at the tip.

  The contact end portion 30a is pressed against the back surface 51b of the mounting plate 51 of the corresponding security sensor 50A, 50B. Step portions 30b and 30b are formed on the front and back surfaces on both sides of the contact end portion 30a, respectively, and a circular recess into which one end of the spring body 31 is inserted between the step portions 30b and 30b. A spring receiving portion 30c is provided. An arm 30d protrudes further outside each stepped portion 30b, and a locking claw 30e forming a locking portion is provided at the tip thereof. A rectangular plate-shaped guide plate portion 30f protrudes from the side opposite to the arm 29d across the axis C1.

  A pair of wide guide rails 38A and 38B having a height of the mechanism accommodating portion 29, that is, the length of the short wall portion 32 is almost half, Low narrow guide rails 39A and 39B are integrally formed. The wide guide rail 38A extends from the opening P1 toward the back, and terminates at an intermediate portion between the openings P1 and P2, and the narrow guide rail 39B extends from the end 38Aa to the opening P2. A locking claw 30e on the upper side of the contact 30A shown in FIG. 4 is locked to the end portion 38Aa which is a locked portion. Similarly, the wide guide rail 38B on the P2 side in FIG. 5 extends from the opening P2 toward the back (front side in FIG. 5), and terminates at an intermediate portion between the openings P1 and P2. A small-width guide rail 39A extends from the locking portion 38Ba to the opening P2. A pair of wide guide rails 38 A and 38 B and narrow guide rails 39 A and 39 B having the same shape as the one short wall portion 32 described above are also pointed with respect to the one short wall portion 32 on the inner surface of the other short wall portion 33. It is formed in a symmetrical arrangement.

  A rectangular plate-shaped partition wall portion 40 that connects the long wall portion 34 and the second side wall 9 to each other is integrally formed at an intermediate portion between the short wall portions 32 and 33. A cross-shaped support protrusion 41 that supports the other end of the spring body 31 of FIG. 4 is integrally formed at each central portion of the main surface of the partition wall 40 facing the openings P1 and P2. . Further, the partition wall 40 has strip-shaped guide pieces 42 extending from the corners on both diagonal sides of the rectangular main surfaces toward the openings P1 and P2 along the side wall 9 and the long wall 34, respectively. 42 is integrally formed. The guide piece 42 guides the contacts 30A, 30B along the moving direction (left-right direction in FIG. 3) by contacting the lower side of the stepped portion 30b of the contacts 30A, 30B in FIG. The mechanism housing portion 29 of the first cover piece 2 in FIG. 3 has the same configuration as the mechanism housing portion 29 of the second cover piece 3.

  The positioning mechanism 28 is a spring of the spring body 31 in a state in which the pair of contacts 30A and 30B are in the relative arrangement shown in FIG. 4 and one end of the spring body 31 is inserted and supported in each spring receiving part 30c. Against the force, it is pushed into the mechanism accommodating portion 29 of FIG. 5 from the openings P1 and P2 on both sides thereof. The pair of arms 30d on both sides of the one contact 30A inserted from the opening P1 is such that the locking claws 30e at the tip end are in sliding contact with the inner side surfaces of the wide guide rails 38A on both sides of the mechanism accommodating portion 29 in FIG. Accordingly, it is slightly deformed by its own elasticity toward the axis C1 side of FIG. 4, and when the locking claw 30e passes through the wide guide rail 38A, the elastic claw 30e is elastically restored, and the locking claw 30e is moved to the end portion (locked). Part) 38Aa. As a result, the contact 30 </ b> A is accommodated while being positioned in the mechanism accommodating portion 29. The other contact 30B is similarly accommodated in the mechanism accommodating portion 29 from the opening P2.

  Thus, as shown in FIG. 6, when the contacts 30A and 30B are positioned between the security sensors 50A and 50B, they are pushed inward by the back surfaces of the security sensors 50A and 50B, that is, the back surface 51b of the mounting plate 51. Thus, the contact end 30 a is pressed against the mounting plate 51 by the restoring force of the compressed spring body 31. As a result, the cover pieces 2 and 3 are positioned at intermediate positions with respect to the gap S between the security sensors 50A and 50B.

  In the above configuration, the decorative cover 1 shown in FIG. 1 has a pair of cover pieces 2 and 3 that are divided into two in the longitudinal direction of the support pole 54, and the other end portions of the cover pieces 2 and 3 are detachable. By connecting with the connecting tool 4, it is attached so as to cover the gap between the security sensors 50 </ b> A and 50 </ b> B supported by the support pole 54. That is, the decorative cover 1 does not use any direct fixing means for the security sensors 50A and 50B, and covers the security sensors 50A and 50B only by connecting the pair of cover pieces 2 and 3 to each other. Can be attached. Therefore, when the support pole 54 is additionally attached to the existing security sensor device, it is not necessary to remove any part of the existing security sensor device from the support pole 54, and the other end portions of the cover pieces 2 and 3. The decorative cover 1 can be easily attached to the security sensor device by a simple operation of simply connecting them with the detachable connector 4. For the same reason, it is easy to remove the decorative cover 1 from the security sensor device.

Each cover piece 2, 3 is provided with a positioning mechanism 28 that is pressed against both security sensors 50 </ b> A, 50 </ b> B of FIG. 2 by a spring force to position the cover pieces 2, 3 in the middle between both mounting plates 51. Therefore, even if the size of the gap between the security sensors 50A and 50B differs depending on the outside diameter of the support pole 54, both cover pieces 2 and 3 are springs of the spring bodies 31 and 31 of FIG. It is automatically positioned at a position where forces are balanced, that is, at an intermediate position of the gap S between both security sensors 50A and 50B in FIG. Therefore, this decorative cover 1 can be used for both security sensors 50A and 50B supported by the support pole 54 having a wide range of pole outer diameters, and can sufficiently cover the gap S from the front-rear direction and the vertical direction. This improves the beauty of the security sensor device. Moreover, the positioning mechanism 28 having a required function can be obtained with a simple structure.
On the other hand, when a decorative cover is attached to one security sensor, it will protrude beyond the other security sensor side, or a part of the other security sensor on the support pole will be exposed, resulting in a loss of aesthetics. It is. Even when the positioning mechanism 28 is not provided, the gap S can be appropriately covered by matching the center of the decorative cover 1 in the left-right direction with the intermediate position of the gap S between the security sensors 50A and 50B.

  Furthermore, since the second cover piece 3 on the lower side of FIG. 3 has an engagement hole 10b that fits into the support pole 54 from the side, the second cover piece 3 is supported by the engagement hole 10b. Since the pole 54 is fitted from the side, it can be moved upward while sliding on the support pole 54 so as to cover the gap between the security sensors 50A, 50B. It can be attached to both security sensors 50A and 50B by an easy operation.

  Further, since the connection wall 10 of the first cover 2 on the upper side in FIG. 3 has the knockout plate 20 that selectively forms the insertion hole 23, the knockout plate 20 remains on the connection wall 10 of the first cover piece 2. If used, it can be used to cover the gap between the security sensors 50A and 50B supported on the upper end of the support pole 54, while the insertion hole 23A through which the support pole 54 is inserted by cutting out the knockout plate 20 is used. , 23B, the first cover piece 2 is disposed between the security sensors 50A, 50B supported at an arbitrary intermediate position other than the upper end of the support pole 54 and used for covering the gap. it can.

  Further, the connecting pole 10 of each cover piece 2, 3 is attached to the wall main body 10 a integrally formed on the both side walls 8, 9 and a support pole 54 between the wall main body 10 a and the wall main body 10 a so as to be detachable. Because the separation wall 18 has the knock-at plate 20 and the same one can be shared as the cover pieces 2 and 3. The cost of the molding die can be reduced. Furthermore, the cover pieces 2 and 3 can be reduced in shape by dividing the decorative cover 1 into two at the intermediate position, so that the packaging shape can be reduced and the transportation cost can be reduced.
