The key switch device of the present invention is attached to an automatic door of a common entrance of a condominium, a management door of a shared electronic device that manages elevator movement, an opening / closing door of an alarm device, and the like. In this type of key switch device, a cylinder lock that is normally operated by operating a general key (plate key) is fixedly attached to a frame-shaped switch mounting plate having a key switch.
[0003]
8 and 9 show a conventional example of a key switch device X for comparison with the present invention. Reference numeral 1 denotes a frame-shaped or box-shaped switch mounting plate, and a key switch (microswitch) 2 is provided inside the switch mounting plate 1 via one or more support rods. The key switch 2 has an actuator (movable piece) and a plurality of lead wires 3. Reference numeral 4 denotes a disk-like driven member for turning on and off the key switch, which is rotatably provided in the fitting hole of the front wall 1c of the switch mounting plate 1 (see FIG. 9). The driven member 4 has a recess 5 at the center, and a “+ -shaped” engaging groove 6 is formed on the front side of the recess 5 as a reference. An actuating plate for an actuator (not shown) is integrally provided at the inner end of the driven member 4 so as to be able to rotate cooperatively against the spring force of the spring member.
[0004]
Therefore, when the driven member 4 rotates, the operating plate rotates cooperatively, and as a result, the key switch (microswitch) 2 is turned on and off via the actuator. Reference numerals 7 denote female thread portions for the fasteners 8 formed at the four corners of the front wall 1c of the switch mounting plate 1, respectively.
[0005]
On the other hand, 10 is a cylinder lock which is detachably mounted on the front wall 1c of the switch mounting plate 1 through the fixing tool 8. The cylinder lock 10 includes a cylinder lock body 11 containing a pin tumbler and the like, and a rectangular mounting substrate 12 provided integrally with a rear end portion of the cylinder lock body 11.
[0006]
The cylinder lock body 11 includes a rotor 14 having a key hole 13 into which a plate key K can be inserted at the center in the axial direction. An engagement body (not shown) that engages with the driven member 4 is fixed to the rear end portion of the rotor 14. The cylinder lock body 11 includes an outer cylindrical body 15 positioned on the outermost side, and a male screw portion 16 is formed on the outer peripheral wall of the outer cylindrical body 15. On the other hand, through holes 17 for fixing tools 8 respectively corresponding to the female screw portions 7 are formed at the four corners of the mounting substrate 12.
[0007]
Next, 18 is an adjusting nut (hexagonal nut) that is screwed into the male threaded portion 16 of the cylinder lock body 11, 19 is a ring having a packing function, and 20 is a radial engaging projection 21 at an appropriate portion of the inner peripheral edge. The fitting link, 22 is a ring-shaped decorative body that is screwed to the front end of the male threaded portion 16 of the cylinder lock body 11, and 23 is a mounting object plate (door, door) having a circular cut hole 24 into which the cylinder lock body 11 enters. A small engaged portion 25 into which the engaging protrusion 21 enters is formed in an appropriate portion of the cut hole 24 in a radial direction.
[0008]
In the above configuration, when the cylinder lock 10 is replaced, the cylinder lock body 11 itself cannot be removed. The reason is that the cylinder lock body 11 and the mounting substrate 12 are integrally formed. Further, the cylinder lock 10 is fixed to the front wall 1c of the switch mounting plate 1 via a plurality of fixing tools 8, and the key switch device X has a plurality of mounting procedures on the mounting target plate 23 as described below. It is because it is fixedly attached after going through.
[0009]
First, the decorative body 22 is removed from the cylinder lock body 11, and the adjustment nut 18 screwed into the cylinder lock body 11 is turned according to the thickness of the panel-shaped attachment target plate 23. Next, the ring 19 and the fitting ring 20 are moved in the direction of the screw base (mounting board) of the cylinder lock body 11. Next, the tip of the cylinder lock body 11 is inserted into the cut hole 24 from the inside of the mounting target plate 23, and the cosmetic body 22 is screwed from the outside so as to be screwed into the tip. At this time, the engagement protrusion 21 of the fitting ring 20 is engaged with the small engagement portion 25 of the attachment target plate 23. Thereafter, the adjustment nut 18 is tightened from the inside, and the key switch device X is securely fixed to the mounting target plate 23.
[0010]
As a conventional example of the key switch device X, a male thread is formed on the outer peripheral wall of the outer cylinder of the cylinder lock, while a ring-shaped female thread is formed on the mounting front plate of the switch body, and the cylinder lock is mounted before the mounting. After being screwed to the face plate, an operating screw that is screwed to the vertical plate of the switch body is operated, and a claw portion of an engaging claw body that is swingably provided on the support member on the switch body side is formed on the outer cylinder body. There is a structure that is engaged with a notch-like engaging portion.
[0011]
However, in the case of this embodiment, a notch-like engaging portion must be formed in the cylinder lock, and the fixing structure of the cylinder lock is complicated.
[0012]
[Problems to be solved by the invention]
As described above, in the conventional key switch device X, the cylinder lock body 11 and the mounting substrate 12 of the cylinder lock 10 are integrally formed, and the cosmetic body is screwed into the cylinder lock body. When the cylinder lock 10 itself is to be replaced because it is necessary to remove it from the mounting plate 23, the cosmetic body 22 is removed from the cylinder lock body 11, the adjustment nut 18 is then loosened, and the cylinder lock is then removed. The cylinder lock 10 could not be removed from the front wall 1c of the switch mounting plate 1 unless the main body 11 was pulled out of the mounting target plate 23 and then the plurality of fixing members 8 were loosened.
[0013]
Accordingly, an object of the present invention is to smoothly rotate the rotating engagement plate by simply operating the operating rod from the inside of the mounting target plate without removing the adjusting nut, the cylinder lock fitting support member, and the like. Can be easily removed from the switch mounting plate, or the cylinder lock can be fixedly attached to the switch mounting plate via the cylinder lock fitting support member. Further, when the operating rod is operated, the rotation engagement plate rotates stably.

The guide roller 35 is fitted in a rotatable and penetrating state.
[0023]
In addition, a plurality (three in this embodiment) of short support rods 36 for rotating engagement plates are arranged at a predetermined interval inside the guide roller 35 positioned on the concentric circle of the driven member 4A.
[0024]
Further, between the horizontal support pins 34 at the right upper and lower corners of the vertical support plate portion 9a, a rotation engagement plate horizontal engagement pin 37 is implanted. In addition, a small drive gear 41 that is fixedly provided at the inner end of the operation rod 40 is disposed at the upper left corner of the vertical support plate portion 9a.
[0025]
Next, main members (the operating rod 40 and the rotation engagement plate 50) of the present invention will be described. As shown in FIG. 1 , the operating rod 40 is a rod-like body provided in a horizontal state on the outside of one side wall 1b of the switch mounting plate 1A. The operating rod 40 has an engaging groove portion 42 for the tool at the rear end portion thereof, and a portion near the tip end portion is supported in a penetrating manner at the upper left corner of the vertical support plate portion 9 a of the front storage case 9. And the small drive gear 41 mentioned above is provided in the inner end part.
[0026]
The rotation engagement plate 50 that rotates via the operation rod 40 is formed in a ring shape, and an engagement tooth 51 that meshes with the small drive gear of the operation rod 40 at a part of the outer circumferential wall that forms the circular hole 53. Is formed. Further, cylinder lock relief notches 52 and 52 through which the engagement protrusions 43 of the rear end of the cylinder lock 10A pass (allow passage) are formed symmetrically at appropriate portions of the inner peripheral wall of the circular hole 53. ing. These notches 52, 52, the rear end portion of the cylinder lock is in communication with the interpolating the circular hole 53 fitted in the through state. In addition, an arcuate guide long hole 54 having a required length in the circumferential direction is formed in the wall surface of the rotation engagement plate 50 from a portion near one notch 52. The engagement pin 37 is engaged with the arcuate guide slot 54.
[0027]
Then, as shown in FIG. 7 , the ring-shaped rotation engagement plate 50 is slidable on the protruding end surface of the short support rod 36 so as to be guided by the outer peripheral wall of the three guide rollers 35 and the engagement pin 37, respectively. And is housed in the housing portion 31 of the front housing case 9 so as to mesh with the small drive gear 41 of the operating rod 40.
[0028]
Next, the cylinder lock fitting support member 60 will be described. The fitting support member 60 is fixed to the front storage case 9 via a plurality of fixing tools 8A. The fitting support member 60 has a function equivalent to a part of the outer cylinder 15 of the cylinder lock body 11 and the mounting substrate 12 of the cylinder lock 10 of the conventional example.
[0029]
That is, 12A is an attachment board having openings 62 and 63 that are fixed to the vertical attachment wall 9c of the front storage case 9 via the fixing tool 8A and allow the rear end of the cylinder lock 10A to pass through. The through small holes 17A for the fixing tool 8A are formed in four partially cut-out corners of 12A. However, this mounting substrate 12A is different from that of the conventional example, and has a protruding pin 61 that fits into the fitting small hole 33 of the front storage case 9 at the upper center portion of the back surface.
[0030]
Further, a through-hole fitting hole 62 into which the rear end portion of the cylinder lock 10A is fitted is formed in the central portion, and this fitting hole 62 allows passage of the rear end portion of the cylinder lock 10A together with the escape portion 63. An opening is formed. Accordingly, the inner diameter of the fitting hole 62 is set so as to be slidably fitted in consideration of the outer diameter of the screwless outer cylinder 15A of the cylinder lock 10A.
[0031]
The mounting substrate 12A has the relief portion 63 which communicates somewhat wider in the radial direction with respect to the fitting hole 62. In this embodiment, the escape portion 63 corresponds to the arcuate engagement protrusions 43 and 43 protruding from the rear end portion of the outer cylinder 15A of the cylinder lock 10A. It is formed left-right or vertically symmetrical.
[0032]
The fitting hole 62 of the cylinder lock fitting support member 60 corresponds to the circular hole of the rotation engagement plate 50, and the symmetrical relief portion 63 can be opposed to the relief notch portion 52 of the rotation engagement plate 50.
[0033]
Reference numeral 64 denotes two separable arcuate support portions that project in opposition from the front surface of the mounting substrate 12A. The arcuate support portions 64, 64 are provided with the above-described engagement protrusions 43, 43 of the cylinder lock 10A. A pair of guide gaps 67, 67 are provided to slide through the left and right or upper and lower sides. The arcuate support portions 64, 64 are integrally formed on the front surface of the mounting substrate 12A. Further, male screw portions 16A into which the adjustment ring 18A is screwed are formed on the outer peripheral walls of the two arcuate support portions.
[0034]
Since the inner space 68 surrounded by the arcuate support portions 64 and 64 is a portion into which the cylinder lock 10A is inserted, the inner space 68 and the fitting hole 62 of the mounting substrate 12A communicate with each other. Yes. The entrance portion of the internal space 68 of this embodiment is set to be slightly large so that the fitting portion 44 provided around the tip of the outer cylinder 15A of the cylinder lock 10A can enter.
[0035]
Finally, the cylinder lock 10A has a very simple form, and includes a screwless outer cylinder 15A having the above-described fitting portion 44, and a key provided inside the outer cylinder 15A via an inner cylinder member. A rotor 14A having a hole 13A, and an engagement piece 45 which is fixedly provided on the rear end surface of the rotor 14A and engages with an engagement groove 6A of the follower 4A on the switch mounting plate 1A side. Engaging protrusions 43 are provided symmetrically at the rear end of the outer cylindrical body 15A.
[0036]
In the above configuration, the key switch device X1 is attached to the mounting target plate 23 such as an automatic door of a shared entrance of a condominium, a management door of a shared electronic device that manages the lifting and lowering of an elevator, and an open / close door of an alarm device as in the conventional example. It is fixedly attached via an adjustment ring 18A or the like. In this case, a cylinder lock fitting support member 60 is fixed to the switch mounting plate 1A via a front storage case (part) 9 and a plurality of fixing tools 8A. In the storage portion 31 of the front storage case 9, as described above, the rotary engagement plate 50 that is rotated by the operating force of the operating rod 40 has the relief cutout portion 52 positioned with respect to the engagement protrusion 43 of the cylinder lock. It rotates so that it displaces and becomes non-opposing ( engagement direction) or facing state ( engagement release direction). It is.
[0037]
Thus, in the cylinder lock 10A, the engagement projections 43, 43 at the rear end thereof can pass through the relief notches 52, 52 of the rotation engagement plate 50 and engage with the locking wall surface 50a of the rotation engagement plate 50. The fitting support member 60 is inserted to the place. When the operating rod 40 is rotated with a finger or the like in such an insertion state, the rotation engagement plate 50 is rotated by the driving force of the small drive gear 41. In this case the rotation engaging plate 50 is reliably guided by the plurality of guide rollers 35 and horizontal engaging pin 37 as shown in Figure 7. In this embodiment, the rotation engagement plate 50 is a kind of movable obstruction for the cylinder lock 10A. Therefore, when the rotation engagement plate 50 is rotated in one direction, the locking wall surface 50a is formed on the inner wall surfaces of the engagement protrusions 43, 43 of the cylinder lock 10A. On the other hand, it is in a surface contact state. Accordingly, the cylinder lock 10A is locked to the rotation engagement plate 50. Therefore, the cylinder lock 10A cannot be pulled out.
[0038]
Therefore, if the cylinder lock 10A is to be replaced now, the attachment target plate (door, panel, glass, etc.) 23 is first opened. When the mounting target plate is opened, the side wall 1b of the switch mounting plate 1A of the key switch device X1 and the operating rod 40 are visible, and the operating rod 40 is rotated either counterclockwise or clockwise. Then, the rotation engagement plate 50 rotates in the direction of disengagement. As a result, the relief notch 52 of the rotation engagement plate 50 faces the engagement protrusion 43 of the cylinder lock 10A, and the cylinder lock is pulled out at that position. When the cylinder lock 10 </ b> A is pulled out from the fitting support member 60, the engagement protrusions 43 and 43 of the cylinder lock 10 </ b> A slide through the guide gaps 47 and 47 of the fitting support member 60.
[0039]
On the other hand, when a new cylinder lock is fixedly attached to the fitting support member 60, the above-described aspect is reversed. First, the engagement protrusions 43, 43 of the cylinder lock 10A are aligned with the guide gaps 47, 47 of the fitting support member 60, and the outer cylinder 15A is pushed into the rotary engagement plate 50 until it is completely inserted. At this time, if the predetermined key K is inserted into the key hole 13A of the rotor 14A, the rotor 14A can rotate. Therefore, in consideration of this point, the engagement piece 45 is engaged with the engagement groove of the follower 4A on the switch mounting plate 1A side. Push the new cylinder lock to the position where it engages with 6A.
[0040]
When the engagement piece 45 of the cylinder lock is thus engaged with the follower 4A on the switch mounting plate 1A side, the engagement protrusion 43 of the cylinder lock is located on the back side of the rotation engagement plate 50, so that When the collar 40 is turned, the cylinder lock 10A is blocked (locked) so as not to come off the rotation engagement plate 50 as described above. As a result, the new cylinder lock is locked to the rotary engagement plate 50 without going through a complicated procedure, and is supported by the switch mounting plate 1A via the fitting support member 60.
[0041]
【Example】
In the embodiment of the present invention, the switch mounting plate 1 may or may not be provided with the front wall 1c as in the prior art. The switch mounting plate 1A is separate from the front storage case 9, but the front storage case 9 may be integrally formed with the switch mounting plate 1A itself. Further, the operating rod 40 may be provided directly on the switch mounting plate 1A or indirectly through another member, and the form of the operating rod 40 can be arbitrarily changed in design.
[0042]
【The invention's effect】
As is clear from the above description, in the present invention, it is possible to operate the operating rod only by operating the operating rod from the inside of the mounting target plate without removing the adjusting nut, the cylinder lock fitting support member, and the like. Since the rotation engagement plate rotates in the disengagement direction by the driving force of the drive gear, the cylinder lock can be easily removed as it is. On the other hand, when the cylinder lock is locked to the switch mounting plate, the cylinder lock When the cylinder lock is inserted into the lock fitting support member and the operation rod is operated, the rotary engagement plate is similarly rotated in the engagement direction by the driving force of the drive gear of the operation rod. Can be desorbed. Moreover, since the guide member and the short support bar are provided in the front storage case (part), it rotates smoothly. In addition, since the rotation engagement plate is supported by a plurality of short support rods and slidably rotates, the rotation engagement plate rotates stably.
