[0015]
1. Adjustment mechanism of camera elevation angle
Reference numeral 30 denotes a camera elevation angle adjustment mechanism, which is provided in the camera unit 3 on the back side of the window plate 11. 3, 4, 9, and 10, 31 is a rectangular opening formed in the front plate 23 in the main body 2 </ b> B, and 32 and 33 are a pair of elastic members that are provided upright on both sides of the opening 31 on the back side. The bearing boss and the switching rib 34 are hexahedral rectangular box-shaped camera cases formed of black or gray resin and fitted with a back cover. On the opposing surfaces of the protruding ends of the pair of bearing bosses 32, a sliding groove having the same width as a support boss 34c described below is formed. Further, a bearing hole is provided in the middle of the sliding groove. Further, a hemispherical protrusion 33 a facing each other is formed at the tip of the switching rib 33. A plurality of reinforcing ribs 35 are formed on the inner wall surfaces on both sides of the side wall that partitions the camera unit 3. A camera body (not shown) is housed in the camera case 34, and its structure is shown in FIG.
[0016]
11 (a) and 11 (b), 34a is a light-receiving cylinder facing the monitoring window 12a, 34b is a non-slip bulge formed so as to swell in multiple rings above and below the light-receiving cylinder 34a, and 34c are both side surfaces. 34d is a horizontal parallel wall sandwiching the support boss 34c, and 34e is a chain hole in which adjacent portions of three cylindrical holes are overlapped and connected in a dumpling shape or a ring shape. The chain hole 34e is provided on a rectangular protruding base 34f, and is formed on an arc having a radius r centered on the support boss 34c. The camera case 34 is inserted into the camera part 3 of the main body 2B from the back side, and the left and right support bosses 34c are slid along the sliding grooves to fit into the bearing holes of the bearing studs 32, and the chain holes 34e are formed. The switch rib 33 is assembled into the camera unit 3 by engaging with the protrusion 33 a.
[0017]
As described above, the main body 2B of the housing incorporating the camera case 34 is attached to the wall surface of the collective entrance with the mounting screws as described above. For example, in the mounting reference state, it is assumed that the projecting portion 33a is fitted into the middle cylindrical hole of the chain hole 34e and the camera case 34 is at the position indicated by the solid line in FIG. When adjusting the elevation angle of the camera, the front end of the camera case 34 facing the opening 31 is pressed against the raised portion 34b, for example, with the index finger. At this time, a thumb is applied to the lower raised portion 34b. While the switching ribs 33 on both sides are pushed and spread by the pressing force of the finger, the camera case 34 rotates counterclockwise around the bearing hole. Then, the fitting of the protruding portion 33a with the chain hole 34e is switched from the middle chain hole 34e to the leftmost chain hole 34e.
[0018]
For this reason, the optical axis OO of the camera reaches the upper limit of the elevation angle θ, and the camera case 34 tilts upward. On the contrary, if a force is applied to the lower raised portion 34b, the camera case 34 is rotated clockwise and restored to the position of the solid line. Further, when a force in the same direction is applied, the fitting of the projecting portion 33a is transferred to the rightmost chain hole 34e, and the camera case 34 tilts downward. In this way, after the elevation angle suitable for the mounting height is set, the lid 2A is mounted on the front surface, and the collective entrance machine 1 is installed on the wall surface of the common entrance in the building. And the camera in the storage chamber 20 of the housing | casing 2 monitors the inside of a viewing angle through the monitoring window 12a of the front.
[0019]
In this case, when the camera case 34 is assembled, the support boss 34 c can be slid along the sliding groove and can be easily fitted into the bearing hole of the bearing boss 32. Further, at the time of adjustment, since the protruding portion 33a moves by intermittently moving the chain hole 34e in sequence, the switching rib 33 can be smoothly switched without unreasonableness. Further, since the bearing boss 32 is sandwiched between the parallel walls 34d, over-rotation of the camera case 34 is automatically prevented.
[0020]
As a result, the elevation angle θ of the camera can be easily adjusted within a range of arbitrary angles by increasing or decreasing the number of circular holes of the chain hole 34e with a simple operation from the front of the apparatus during mounting. In addition, by increasing or decreasing the radius of the circular hole of the chain hole 34e, the engagement strength between the protruding portion 33a and the chain hole 34e can be adjusted. Multiple annular ridges 34b formed above and below the light receiving tube 34a can prevent finger slipping during adjustment, improve operability and prevent injury. In addition, since the camera case 34 is rotatably supported by the bearing boss 32 and the switching rib 33, the camera elevation angle adjustment mechanism is remarkably simple in comparison with the above-described conventional apparatus using a tilting arm or a screw rod. Can be provided.
[0021]
2. Push button mechanism
Reference numeral 40 denotes a push button mechanism, which is configured in the operation unit 4. Reference numerals 41 and 42 denote a plurality of button holes having substantially the same shape, and reference numeral 43 denotes a button member. The button holes 41 and 42 have substantially the same rectangular shape and are formed at the same position on the lid 2A and the main body 2B. A front view, a side view, and a cross-sectional view of the button member 43 are shown in FIGS. 12 (a), 12 (b), and 12 (c). The button member 43 is composed of two parts, a square button part 44 and an apron-like extension part 45 projecting to the front side below the button part 44. Reference numeral 46 denotes a push button provided on the button portion 44, which is connected to the peripheral portion through a thin connecting portion 47 that provides springiness and protrudes in an inverted convex shape in cross section. The button member 43 is made of a rubber material such as silicone rubber having a hardness of about 50 degrees and elastic, and is integrally molded with these resins.
[0022]
A total of 14 push buttons 46 (3 × 4) +2 are formed on the button member 43. On the surface of each push button 46, numerical values “0 to 9”, “asterisk”, “cancel”, “voice guide” and “call” signs and characters are displayed by printing or the like. Such a button member 43 is mounted by inserting all the push buttons 46 into the button holes 42 of the main body 2B from the back side. In the mounted state, the front end of the push button 46 is slightly exposed on the operation surface on the lid plate 21 and the lower ends face each other close to the tact switch group mounted on the second substrate 17 (FIG. 5). ).
[0023]
A plan view of the mounting state of the button member 43 is shown by a two-dot chain line in FIG. As shown in the figure, the button member 43 is elastically interposed in the gap between the main body 2 </ b> B and the second substrate 17 and surrounds the 14 tact switches 17 a on the second substrate 17. Further, the extending portion 45 that hangs down from the front surface of the button member 43 covers the front surface of a setting switch such as the DIP switch 17b that is mounted below the tact switch 17a and has a different function. In addition to the DIP switch 17b, the front surface of the address switch 17c of the collective entrance 1 and the volume switch 17d and the reset switch 17e for adjusting the volume of the speaker described below are also covered with the extending portion 45.
[0024]
As described above, according to the button member 43 of the first embodiment of the present invention, the front surfaces of the various setting switches including the tact switch group 17a mounted on the second substrate 17 and the DIP switch 17b below the tact switch group 17 are simultaneously covered. be able to. Therefore, the mounted components on the second substrate 17 having different functions and functions can be uniformly isolated from the external environment such as wind and rain. As a result, the number of parts of the operation unit 4 is reduced, and assembling is easy and an effect can be expected in terms of cost. When changing the setting of the DIP switch 17b and the like, first, the cover plate 1 is removed from the main body 2B, and the extending portion 45 is turned to the front side from the opening 45b formed below the button hole 42 of the main body 2B. Then, the DIP switch 17b and the like may be exposed and adjusted. Thus, since the button member 43 is formed of a rubber material, the extending portion 45 is easily turned over. Further, the extended portion 45 can be formed by extending the button member 43 without providing another member. As described above, since the important address switch 17c and the like for setting the address of the collective entrance machine 1 are covered by the extending portion 45, it is possible to prevent malfunction and failure due to contact and operation outside the parties concerned.
[0025]
Note that 61 shown above the tact switch group 17a in FIG. 13 is the above-described microphone (microphone). Reference numeral 17f denotes a seven-segment display that displays a four-digit numerical value facing the display window 12b, and 17g denotes a plurality of light-emitting diodes arranged in a line, each of which mounts the second substrate 17 together with the tact switch group 17a. Mounted on the surface. The plurality of light emitting diodes 17g are respectively inserted into light shielding cylinders 17h provided on the back surface of the main body 2B (FIGS. 4, 9, and 10), and face the semitransparent triangle 12d of the guide display 12c. Both the 7-segment display 17f and the light-emitting diode 17g sequentially turn on and display numerical values and items of the guidance display 12c in accordance with the key input in association with the operation of the push button 46 of the push button mechanism 40. .
[0026]
3. Speaker mechanism
FIG. 14 is an exploded explanatory view showing the configuration of the speaker mechanism 50. 14A and 14B, 51 is a speaker, 52 is a mounting box, and 53 is a metal fixing plate. The mounting box 52 is made of resin, and as shown in FIG. 14B, includes a square plate portion 52b having a horizontal sound emitting groove 52a and a cylindrical sound insulating wall 52c into which the speaker 51 is inserted. Cylindrical fixing portions 52d projecting like ears are provided at the four corners of the square plate portion 52b, and the screw bosses 52e of the main body 2B are fitted into the fixing portions 52d. 54 is a left and right gap seal, 55 is a ring-shaped packing, and 56 is a waterproof sheet. A slightly thicker polyurethane is used for the gap seal 54, and in the first embodiment, a nonwoven fabric or a cloth mainly composed of a nonwoven fabric is used for the waterproof sheet 56. Although not shown, a rubber washer is provided between the gap seal 54 and the screw boss 52e.
[0027]
Polyethylene films that are frequently used as this type of waterproof film often break easily due to contact during assembly or the like, and are often not waterproof. On the other hand, since the nonwoven fabric is composed of fibers, it is deformable and has no cracks. In particular, when a non-woven fabric is disposed on the front surface of the cone, since both waterproofness and air permeability are provided, the generated sound wave is almost propagated forward as it is, and leakage sound into the inside of the housing 2 hardly occurs. Therefore, there is also a feature that the sound wave generated by the speaker 51 is concentratedly emitted from the sound emitting grooves 13 and 52a to the front surface of the collective entrance machine 1 through the opening 52f. Here, the nonwoven fabric as the waterproof sheet 56 has a thickness of 300 μm and an air permeability of 35 ml / cm.²-The one of sec is used, and is cut into a circle larger than the outer diameter of the speaker 51.
[0028]
Then, as shown in FIG. 14A, the speaker 51 is covered with a waterproof sheet 56 made of a nonwoven fabric on the front surface of the cone, and is surrounded by a packing 55 and a gap seal 54 and sealed in a sound insulation wall 52c of the mounting frame 52. Housed in state. In this way, the mounting frame 52 that houses the speaker 51 is fixed to the back surface of the main body 2 </ b> B via another gap seal 54. Therefore, similarly to the push button mechanism 40 using the button member 43 described above, it does not occur that it is adversely affected by changes in the external environment such as seasons such as wind and rain and weather. In addition, since it is housed and fixed in the sound insulation wall 52c of the mounting frame 52 in a sealed state, there is almost no vibration, and deterioration of sound quality is prevented.
[0029]
On the other hand, as shown in FIG. 10, a pot-shaped sound insulating wall that surrounds the microphone 61 together with the sound emitting unit 5 having the speaker mechanism 50 is contained in the housing area surrounded by the low-side side wall 24 on the back side of the main body 2B. 29 is provided. Although not shown in detail, the microphone 61 is also covered with a waterproof sheet 66 made of a non-woven fabric or a cloth mainly made of non-woven fabric similarly to the speaker 51 and is opposed to the sound collection hole 14 by being surrounded by the sound insulation wall 29. (FIGS. 5 and 13). As a result, according to the speaker mechanism 50 of the present invention configured as described above, noise noise is not added to the microphone 61 provided in the same housing.
[0030]
Incidentally, FIG. 15 shows the input characteristics of the microphone 61 indicating the degree of influence of the waterproof sheet according to the experiment results of the inventors of the present application. FIG. 15A shows a microphone without a sheet, and FIGS. 15B and C show characteristics when a nonwoven fabric sheet and a polyethylene film sheet are used, respectively. As is clear from the comparison diagram shown in FIG. 15, according to the speaker mechanism 50 and the microphone 61 of the present invention using the non-woven waterproof sheets 56 and 66, the frequency bandwidth is prevented from being narrowed compared to the polyethylene sheet. It can be considered that the sound quality during transmission and reception is also improved.
[0031]
4). Lock mechanism
A lock 7 that uses the reverse master key described above is arranged on the right side of the lower speaker section 5 of the housing 2. The lock mechanism 70 of the lock portion 7 is shown in FIGS. 16 (a) and 16 (b). If the attachment structure of the lock mechanism 70 of Embodiment 1 is divided roughly, the two attachment types are employ | adopted based on the difference in the structure of a basic lock. FIG. 16 (a) shows one type of ring type, and FIG. 16 (b) shows another structural type frame type. Reference numeral 71 denotes a pair of Φ-shaped screw bosses, which are formed on the back surface of the lid 2A (FIG. 8 and others). 71a is a cylindrical portion of the screw boss 71, and 71b is a plate-like portion formed on the left and right of the cylindrical portion 71a. A metal nut (or a metal knurl) is inserted into the axial center of the cylindrical portion 71a, and protrudes up and down on the back surface side of the lid 2A with a lock hole 70a forming two ears therebetween. By providing the screw boss 71 and providing the mounting plate 73 with a notch 73b corresponding to the screw boss 71, the mounting plate 73 can be prevented from rotating.
[0032]
In FIG. 16A, 72 is a decorative ring in which a screw for axial rotation is provided on the threaded surface of an inner peripheral screw, 73 is a square mounting plate, 74 is a rotation stopper provided with a claw 74a, 75 Is a packing, 76 is an adjusting nut, and 77 is a switch body in which a screw insertion portion 77a is formed on the outer periphery and a lead wire 77b is connected. 73a is an insertion hole formed in the mounting plate 73, and 73b is an arcuate cutout formed on the opposite side. The inner diameter R of the insertion hole 73 a of the mounting plate 73 corresponds to the insertion diameter of the insertion portion 77 a of the switch body 77, and the distance between the notches 73 b and the distance between the two so that the arc contacts the screw bosses 71. It is made approximately equal to the radius of the cylindrical portion 71a.
[0033]
16 (a), the adjustment nut 76 is first screwed into the insertion portion 77a of the switch body 77 slightly deeply, and then the packing 75 and the rotation stopper 74 are fitted. The mounting plate 73 is applied to the back surface of the lid 2A while aligning the insertion hole 73a and the lock hole 70a. The switch body 77 fitted with the rotation stopper 74 or the like is inserted into the insertion hole 73a of the applied mounting plate to expose the tip. The decorative ring 72 is screwed into the insertion portion 77a exposed on the front surface. Next, the rotation stopper 74 is moved forward, and the tip of the claw 74a is inserted into the groove of the decorative ring 72 to prevent rotation. Then, if the adjustment nut 76 is screwed forward, the insertion portion 77a is tightened and the switch body 77 is attached to the lid 2A.
[0034]
When the switch body 77 is mounted, the mounting plate 73 is attached in a fitted state with the opposite sides provided with the notches 73b contacting the side surfaces of the cylindrical portion 71a and the plate-like portion 71b of the screw boss 71. Therefore, the lock mechanism 70 is constructed that does not require a special mounting screw for mounting the reverse master key. Therefore, according to the first embodiment using the mounting plate 73 of this configuration, it does not take time for assembly or replacement work, which contributes to the reduction of the number of parts.
[0035]
In the present invention, there is prepared a mounting plate 73 in which the inner diameter of the insertion hole 73a is formed stepwise, and various types of reverse master keys with different insertion diameters manufactured independently by each manufacturer of this type. Can be installed without problems. When the insertion diameter of the switch body 77 is relatively large and substantially equal to the lock hole 70a, the claw 74a is directly inserted into the groove of the decorative ring 72 through the ear of the lock hole 70a without using the mounting plate 73. Then, the adjustment nut 76 is tightened from the back side, and the switch body 77 is attached to the lid body 2A.
[0036]
In FIG. 16B, 78 is a cylinder, and 79 is a mounting frame. 79a is an attachment screw for the frame 79, 79b is an attachment screw for the cylinder 78, and 79c is a lead wire. The two attachment screws are screwed into a metal nut inserted into the cylindrical portion 71a of the screw boss 71, and the frame 79 is attached to the back surface of the lid 2A. The key is inserted into the keyhole of the cylinder 78 as far as it will go, and the cylinder 78 is fully screwed into the nut on the frame 79 side from the front while keeping the inserted key on the central axis.
[0037]
After the temporarily tightened cylinder 78 is rotated and the keyhole is adjusted to a predetermined position, the lock mechanism 70 is assembled by fixing the cylinder 78 with the mounting screw 79b. In the lock mechanism 70 of FIG. 16B, the screw boss 71 formed on the lid 2 </ b> A is directly used for attaching the cylinder 78. As described above, according to the first embodiment of the present invention, a pair of Φ-shaped screw bosses 71 formed on the back surface of the mounting surface and the opposite sides are inserted between the screw bosses 71 in a fitting manner.
