Description

  The present invention relates to an anti-sway structure for a lock box for preventing the back side of the lock box housed in the door in a cantilevered support state by fixing only the front back plate to the mouth of the door.

  A lock box, which is a main body of a locking / unlocking device provided on a door, is attached and fixed to the door with various attachment structures. Generally, as shown in FIG. The lock box 505 is inserted into the recess 500a or the cavity 500b from the side of the mouth, and the flange-shaped front plate 507 formed on the side of the lock box 505 is fixed to the door mouth 501 with a screw or the like. It is structured to be fixed with. The lock box 505 disposed in the door has an operation member 511 that protrudes inward from the front and back surfaces of the door 500 via a seat member, so-called escation 509, for example, a shaft 511a such as a handle, a lever, or a knob. It is connected to the bearing of the lock box 505. Support pillars arranged between the seat members pass through the periphery of the lock box 505, and the front and back seat members 509 are positioned and fixed to the door 500 with a plurality of support pillars and screws.

  The bearing portion arranged in the lock box 505 is at a distance from the mouth end side, and the back side of the lock box is supported by the door 500 compared to the mouth end side fixed to the door 500 via the front plate 507. In other words, the state is supported only by the shaft 511a of the operation member 511 arranged on the front and back of the door 500. That is, the lock box 505 is supported in a cantilever manner only by the front plate 507. For this reason, the lock box 505 has its back side swung toward the front and back surfaces of the door 500 with respect to the side of the door, and the shaft core is not straightened or eccentric, or one seat member 509 is fixed. However, the accuracy was not high, such as the other being displaced.

  For this reason, the lock box 505 moves inside the door, that is, swings in the direction of the front and back surfaces of the door, causing malfunction of cylinders and handles, and the lock box 505 swings during assembly, resulting in poor workability. Sometimes it was.

  Conventionally, with respect to the problems as described above, a steady rest has been provided on the back surface, which is the facing surface of the front and back cases (see, for example, Patent Document 1). The steady rest includes a plurality of adjusting plates whose thickness can be changed, supports the position of the lock box from the front and back cases, and prevents the lock box from swinging with respect to the door.

  However, in this example, adjustment plates are provided on the front and back cases, respectively, and the lock box is sandwiched from the front and back to adjust the position of the lock box. For example, the distance between the cases is large, that is, the door is thick. In addition, in the case of being biased to either the center in the thickness direction or the like, a large number of adjustment plates are required, and the amount of protrusion from each must be devised in order to balance the thickness direction. In particular, when the front and back cases are attached to the doors, the adjustment plates protrude from the doors, which is not very good for workability.

In addition, various holes are drilled in the door 11 corresponding to the position where the lock box 19 is mounted. Typical examples include wiring holes 89, escation connection holes 91, handle shaft holes 93, spare holes 95, cylinder rotation transmission link shaft holes 97, escation connection holes 99, cylinder lock holes. 101 etc. are mentioned. These holes shown in FIG. 5 are covered, for example, by attaching the outer escation unit 27b.

FIG. 6 is a perspective view of the upper portion of the lock box held between the locking collars, and FIG. 7 is an exploded perspective view of the adjustment plate, the locking collar, and the press-fitting nut shown in FIG.
The above-described brace collar 49 that is externally inserted into the stud nut 39 is disposed in the through hole. The brace collar 49 projects the pair of support arms 45 in the same direction in a direction perpendicular to the axis 43 of the stud nut 39. A space 47 is formed between the pair of support arms 45. The upper side portion of the lock box 19 is fitted in the spacing space 47 in the thickness direction. That is, the locking collar 49 can sandwich the lock box 19 with the support arm 45.

  On the outer periphery of the stud nut 39, there is an adjustment plate 51 having a desired thickness between the back plate 29 of one escation unit 27 and the anti-vibration collar 49, in this embodiment, a plurality of thin adjustment plates 51. Extrapolated. If the number of adjustment plates 51 is reduced, the position of the anti-vibration collar 49 in the direction approaching the outdoor back plate 29b of one outer escation unit 27b is adjusted, and if the number of adjustment plates 51 is increased, The stop collar 49 is adjusted in the direction away from the outdoor back plate 29b of one outer escation unit 27b. Thus, the position of the anti-vibration collar 49 from the outdoor back plate 29b can be adjusted by increasing or decreasing the number of adjustment plates 51.

  The brace collar 49 is prevented from falling off the tip 35 by a press-fit nut 53 attached to the tip 35 of the stud nut 39. Since the press-fit nut 53 having a retaining function is attached from the distal end portion 35 of the stud nut 39, a complicated structure for restricting the dropout of the anti-vibration collar 49 on the outer periphery of the stud nut 39 becomes unnecessary. As a result, the anti-vibration collar 49 can be positioned in the axial direction with the adjustment plate 51 and the press-fit nut 53 interposed therebetween. That is, depending on the object to be attached, the position of the stud nut 39 in the axial direction changes depending on the number of adjusting plates 51 and the anti-vibration collar 49. With this press-fit nut 53, the position is maintained by press-fit mounting. Thus, the trouble of forming a groove on the outer peripheral surface of the stud nut 39 is eliminated.

  The brace collar 49 is rotatably supported by the stud nut 39 and is in non-contact with the lock box 19 in a rotational posture in which the support arm 45 protrudes toward the wooden end 13. That is, when the lock box 19 is inserted, the support arm 45 can be disposed at the retracted position. By rotating at least 90 degrees from the non-contact posture, the pair of support arms 45 are arranged at positions where the lock box 19 is sandwiched. In this steady rest structure, the outer escation unit 27b can be inserted without interfering with the lock box 19 at the retracted position in which the support arm 45 protrudes toward the mouthpiece 13, and after the outer escation unit 27b is inserted. In other words, the lock collar 19 is pinched by the support arm 45 so that the swing collar 49 is rotated, thereby preventing the shake. Accordingly, the lock box 19 can be easily prevented from being shaken by simply rotating the lock collar 49 and sandwiching the lock box 19 with the support arm 45.

  In the present embodiment, the adjustment plate 51 is formed of an annular plate. The adjustment plate 51 through which the stud nut 39 penetrates can be detached from the stud nut 39 only in the penetrating direction, and the stud nut 39 cannot be detached in the direction orthogonal to the axis. By using such a penetrating member, the adjustment plate 51 cannot be dropped off and can be reliably extrapolated to the stud nut 39.

  The adjustment plate 51 may be formed so as to be detachable from the direction orthogonal to the axis of the stud nut 39 by being opened in a C shape. By making the adjustment plate 51 into a C shape with the opening opened, it is possible to press-fit the opening from the direction orthogonal to the axis of the stud nut 39 and attach the adjustment plate 51 to the stud nut 39. As a result, the position of the brace collar 49 can be adjusted in the axial direction even after the stud nut 39 is mounted.

Next, the operation of the lock box steadying structure having the above-described configuration will be described.

  At that time, as shown in FIG. 8B, the through-hole 33 is provided with an anti-vibration collar 49 that is externally inserted into the stud nut 39 and is rotatable. Since the support arm 45 is rotated so that the support arm 45 faces the end 13 or the opposite side, the support arm 45 does not hit the lock box 19 when inserted into the through hole 33.

  To lock the lock box 19, the lock collar 49 is rotated in the through hole 33 (FIG. 9C) so that the pair of support arms 45 are in contact with both sides of the lock box 19. Hold it. In this state, the lock box 19 is placed at a predetermined position in the thickness direction of the door 11.

  Then, the inner escation unit 27a is attached by screwing the back plate clamping fixing screw 41 passed through the indoor back plate 29a into the female screw 37 of the stud nut 39 as shown in FIG. It is fastened and fixed to the outer escation unit 27b.

  Both escation units 27 are provided with operation members 21 such as handles and knobs, cylinder locks, thumbturns, and the like, and their shaft portions 23 are appropriately connected to respective positions in the lock box. . Further, after attaching the escation unit 27, these operation members 21 may be attached to the lock box 19.

  As described above, in this steady rest structure, the rest collar 49 is externally attached to the stud nut 39 for sandwiching and fixing the pair of escation units 27 to the door 11 from the front and back, and the support arm 45 of the rest collar 49 When the back side portion of the lock box 19 is sandwiched in the thickness direction, the steady rest can be easily made with a simple structure using a small number of parts.
