Description

  The present invention relates to a lock box positioning mechanism that positions and locks a lock box built in a hollow door without rattling on both inner wall surfaces of the door.

  The lock box built in the door includes a knob attached to the outside of the door, a cylinder lock exposed to the outside, a thumb turn exposed to the inside, and the like. The lock box is provided with a dead bolt, which is a locking member, so as to be able to advance and retreat from an end surface on the opposite side of the door suspension, so-called a butt. The deadbolt is inserted into the keyhole of the cylinder lock exposed to the outdoor side and inserted into the keyhole to rotate, so that the deadbolt is moved forward and backward from the door's mouth and locked and unlocked on the door frame side. From the indoor side, the thumb turn knob is advanced and retracted only by rotating, so that the door can be easily locked and unlocked.

If the lock box is installed obliquely with respect to the door in a state where it is built in the door, it will hinder the mounting of components such as knobs, cylinders and thumb turns on the front and back surfaces of the door, or latches and dead bolts. In particular, when the door is hollow, the lock box cannot be supported only by the end portion, and some support member is required between the door inner surface and the lock box. Conventionally, in a general hollow door, the center in the thickness direction of the lock box coincides with the center in the thickness direction of the door, and the lock box is attached without any trouble. In order to match the door center and the lock box center, support members of the same length are provided on the front and back surfaces of the lock box, for example, rod-shaped protrusions, stud bolts, or the like. Like a stopper, a hook-shaped member that protrudes the same distance by rotating a screw from the side of the mouth is used to support both inner wall surfaces of the door.

However, in recent years, due to demands such as door design, the number of doors to which a lock box can be attached is increasing in the structure where the center of the lock box does not coincide with the center in the thickness direction of the door. In this case, in the door of the hollow structure described above, support members such as rod-shaped protrusions and stud bolts are separately prepared with left and right equal lengths, or in the case of the steadying device disclosed in Patent Document 1 For example, the length of one of the pair of hook-shaped members is cut shorter than the other, so that the protruding length is changed to correspond to the eccentricity of the lock box support position. All of these countermeasures require complicated and separate processing to cut off the support member and the hook-shaped member, and when such processing work is performed at the lock box installation site, the workability of mounting the lock box is reduced. As a result, the positioning accuracy of the lock box also decreased. This may result in a deterioration in the door erection capability or a crime prevention problem.
Furthermore, in the conventional lock box positioning mechanism, there is a mechanism in which a support member that contacts the inner wall surfaces of the doors and supports the lock box contacts the inner wall surface of the door by point contact. In such a case, a predetermined lock box is used. When the contact pressure is increased in order to obtain a supporting force, stress concentration occurs on the inner wall surface of the door, and the inner wall surface of the door may be deformed to the outer surface side. Such a situation was likely to occur particularly during maintenance such as replacement of the lock box.

  The present invention has been made in view of the above situation, and even in a lock box mounting structure in which the center in the thickness direction of the lock box does not coincide with the center in the thickness direction of the door, the lock box is highly accurately attached to both inner wall surfaces of the door. An object of the present invention is to provide a lock box positioning mechanism that can be reliably supported and does not cause deformation of the inner wall surface of the door, thereby improving workability and mounting accuracy.

According to the positioning mechanism of the lock box according to claim 1 of the present invention, a fixing plate is fixed to the lock box, and a pair of legs is supported to the fixing plate via a pin so that the legs can be freely opened and closed, Since the pressing member that can be pressed by the operating means is brought into contact with the base end seating surfaces of the pair of legs, and the pressing member is swingably held by the holding member via the swing shaft in the vertical direction. An open / close support leg centered on the pin is swung to one side or the other side of the lock box at a certain open leg angle by swinging of the pressing member in contact with the base seat surface. As a result, the protruding length of the leg tip from both sides of the lock box can be varied. Therefore, even in the case of a lock box mounting structure in which the center in the thickness direction of the lock box does not coincide with the center in the thickness direction of the door, if the operating means is operated and the opening / closing support leg is pressed via the pressing member, the deviation will be avoided.

Preferred embodiments of a lock box positioning mechanism according to the present invention will be described below in detail with reference to the drawings.
1 is a perspective view of an upper portion of a lock box provided with a lock box positioning mechanism according to the present invention, FIG. 2 is an exploded perspective view of the lock box positioning mechanism shown in FIG. 1, and FIG. It is a side view of the lock box provided with the mechanism.
The positioning mechanism of the lock box according to the present embodiment works so as to abut and support both side surfaces of the lock box 11 which is built in with one end surface fixed to the end of the hollow door, on both inner wall surfaces of the facing door. This lock box positioning mechanism is provided in at least one of the upper and lower surfaces of the lock box 11 or in an intermediate position. In the present embodiment, as shown in FIG. 3, the lock box 11 is provided on each of the upper surface and the lower surface.

  By providing a positioning mechanism on each of the upper and lower parts of the lock box 11, the lock box 11 is supported on both inner wall surfaces of the door up and down, and the number of support points increases, so that the lock box 11 can be positioned more reliably. Is now possible. In addition, since the positioning mechanism provided in the upper part and the lower part of the lock box 11 is substantially the same structure, in the description of the present embodiment, only the positioning mechanism provided in the upper part shown in FIG. 1 will be described as an example.

  The lock box positioning mechanism includes a fixed plate 1, an opening / closing support leg 3, a pressing member 5, a holding member 7, and an adjusting screw 9 as an operation means as main components. As shown in FIG. 2, the fixed plate 1 includes an upper fixed plate 13 and a lower fixed plate 15. Support holes 17 and 17 are formed in each of the upper fixing plate 13 and the lower fixing plate 15, and the upper and lower ends of the pins 19 whose axis is in the vertical direction are supported in the support holes 17.

  Between the upper fixing plate 13 and the lower fixing plate 15, an opening / closing support leg 3 including a pair of legs 21 and 23 is supported by a pin 19 through a pin hole 25 so as to be swingable. A recess 27 is formed at the end of the lower fixing plate 15 at the mouth end, and the recess 27 accommodates the pressing member 5 and the holding member 7. The holding member 7 has upper and lower pieces and is formed in a U shape. Protrusions 29 and 29 are provided on both sides of the holding member 7, and the protrusions 29 and 29 engage with holding windows 31 and 31 provided on the side portions of the lower fixing plate 15 and the upper fixing plate 13. As a result, the holding windows 31 are held slidably in the longitudinal direction of the upper fixing plate 13 and the lower fixing plate 15 within a range in which the projections 29 29 move within the holding windows 31, 31.

  A support piece 33 is bent and raised at the end of the lower fixing plate 15, and a U-shaped support groove 35 is formed in the support piece 33. A circumferential groove 37 of the adjusting screw 9 is fitted into the support groove 35. The tip of the adjustment screw 9 supported by the support piece 33 is screwed into the female screw 39 of the holding member 7. Therefore, the holding member 7 is slid in the longitudinal direction of the upper fixing plate 13 and the lower fixing plate 15 by rotating the head 41 of the adjusting screw 9 by an adjustment jig, for example, a tool such as a screwdriver (plus driver). Is done.

  C-shaped bearing portions 43 and 43 are formed on the upper and lower pieces of the holding member 7. Oscillating shafts 45, 45 projecting upward and downward of the pressing member 5 are inserted into the bearing portions 43, 43. The pressing member 5 has a pair of pressing pieces 47 and 47 that are bent in a substantially C shape on both sides. In the state where the pressing member 5 is swingably held by the holding member 7, the left and right pressing pieces 47, 47 come into contact with the base seat surfaces 21 a, 23 a of the opening / closing support leg 3 ( (See FIG. 4 (a)).

  Therefore, when the holding member 7 is slid in the direction approaching the opening / closing support leg 3 by rotating the adjusting screw 9, the pressing member 5 approaches the opening / closing support leg 3 via the holding member 7. Moved to. As a result, the pressing pieces 47 of the pressing member 5 press the base end seat surfaces 21a and 23a of the pair of legs 21 and 23, respectively. The pair of legs 21 and 23 are swung around the pin 19 in the direction in which the leg-side distal ends 21b and 23b are opened by the base end seating surfaces 21a and 23a being pressed by the pressing pieces 47 and 47. It has become so.

  Further, in this pressed state, the pressing member 5 is swingably held by the holding member 7 via the swinging shafts 45, 45, so that the open / close support leg 3 has an opening leg angle. While being held, the pressing member 5 is swung by swinging, so that the left and right legs 21 and 23 can protrude from both side surfaces of the lock box 11 with different protruding lengths.

  Further, in the positioning mechanism of the lock box 11, the contact members 71 and 73 rotate on the open leg side tips 21 b and 23 b of the pair of opening and closing support legs 3 via the shafts 81 and 83 in the same direction as the pin 19. It is supported freely. In the present embodiment, the contact members 71 and 73 are made of a strip-shaped plate material in which R is formed at one corner. In the contact members 71 and 73, when the open leg side tips 21b and 23b of the open / close support leg 3 are opened, the open leg side outer surfaces 71a and 73a contact the inner wall surface of the door. Protrusions 75 and 75 that prevent the contact members 71 and 73 from rotating in the reverse direction are provided on the legs 21 and 23, respectively.

  The upper fixing plate 13 holds the open / close support leg 3 so as to be freely openable / closable, and is fixed to the lock box 11 integrally by the assembly screws 51 while holding the holding member 7, the pressing member 5, and the adjusting screw 9. In this way, the positioning mechanism is fixed to the upper and lower surfaces of the lock box 11. As shown in FIG. 3, the fixed lock box positioning mechanism is such that the head 41 of the adjusting screw 9 is exposed to the mouth from a through hole 55 formed in the mounting fixing plate 53 exposed to the mouth. It has become. Therefore, the adjustment screw 9 can be rotated by a tool inserted into the through hole 55.

  A front plate (not shown) is further attached to the surface of the attachment fixing plate 53. Since the head 41 of the adjustment screw 9 exposed to the mouth is covered with a front plate fixed to the mouth, the adjustment screw 9 that is not required after the lock box 11 is attached is covered, improving the appearance and adjusting. A reduction in the support strength of the lock box 11 due to the rotation of the screw 9 is prevented.

Next, the operation of the lock box positioning mechanism configured as described above will be described.
FIG. 4 is an operation explanatory view showing the support process of the opening / closing support legs in the lock box mounting structure in which the center in the thickness direction of the lock box coincides with the center in the thickness direction of the door, (a) (b) (c) 5 is an operation explanatory view showing the support process of the opening / closing support legs in the lock box mounting structure in which the center in the thickness direction of the lock box does not coincide with the center in the thickness direction of the door, as shown in (a), (b), and (c).
As shown in FIG. 4, in the lock box mounting structure in which the center in the thickness direction of the lock box 11 coincides with the center in the thickness direction of the door 61, the pressing member 5 is rotated by rotating the adjustment screw 9. The base end seating surfaces 21a and 23a are pressed, and as a result, as shown in FIGS. 4 (b) to 4 (c), the open leg side tips 21b and 23b of the open / close support leg 3 are evenly opened. go. As a result, the open leg side tips 21b and 23b of the open / close support leg 3 simultaneously abut against the inner wall surfaces 61a and 61b of the door 61, and the lock box 11 is fixed to the end 63 and the inner wall surfaces 61a and 61b. The door 61 is positioned at the center of the door 61 without rattling by the opening / closing support leg 3 in contact with the door. At this time, the opening / closing support leg 3 always comes into contact with the inner wall surfaces 61a, 61b via the contact members 71, 73, so that the opening / closing support leg 3 does not make point contact and stress is applied to the door inner wall surface 61a. Concentration does not occur.

  On the other hand, as shown in FIG. 5, in the lock box mounting structure in which the center LC in the thickness direction of the lock box 11 does not coincide with the center DC in the thickness direction of the door 61, the center LC of the lock box 11 is located with respect to the center of the door 61. They are arranged eccentrically by δ. In this state, as shown in FIG. 5B, when the adjustment screw 9 is rotated, the opening / closing support legs 3 are opened and closed uniformly at first. Thereafter, the leg tips 23b of one pair of legs 23 come into contact with the adjacent inner wall surface 61a. When the adjustment screw 9 is further rotated in this state, only the other leg 21 of the open / close support leg 3 is opened while the one leg 23 is in contact with the inner wall surface 61a. That is, when the pressing member 5 swings with respect to the holding member 7, the other leg 21 side opens. As a result, finally, as shown in FIG. 5C, the open leg side tip 21 b of the other leg 21 comes into contact with the inner wall surface 61 b, and the lock box 11 has one end surface fixed to the end 63. The pair of legs 21 and 23 come into contact with the inner wall surfaces 61a and 61b which are separated from the lock box 11 at different distances, and are positioned on the door 61 without rattling. Even in this case, the opening / closing support leg 3 always comes into contact with the inner wall surfaces 61a and 61b via the contact members 71 and 73, and stress concentration does not occur on the door inner wall surface 61a.

  Therefore, according to the above-mentioned lock box positioning mechanism, the fixing plate 1 is fixed to the lock box 11 and the pair of legs 21 and 23 are supported to the fixing plate 1 via the pins 19 so that the legs can be opened and closed. Then, a pressing member 5 that can be pressed by the rotation of the adjusting screw 9 is brought into contact with the base end seating surfaces 21a and 23a of the pair of legs 21 and 23, and the pressing member 5 is made to swing in the vertical direction. Since the holding member 7 is swingably held via 45, 45, the opening / closing support leg 3 which is opened and closed with the pin 19 as the center swings the pressing member 5 which is in contact with the base end seat surfaces 21a, 23a. Therefore, the lock box 11 is swung to one side or the other side of the lock box 11 at a fixed leg angle. As a result, the protruding lengths of the open leg side tips 21b and 23b from both sides of the lock box are varied. be able to.

  Thereby, even in the mounting structure of the lock box 11 in which the center LC in the thickness direction of the lock box 11 does not coincide with the center DC in the thickness direction of the door 61, the adjustment screw 9 is rotated and opened and closed via the pressing member 5. If the support leg 3 is pressed, the open / close support leg 3 contacts either the left or right door inner wall surface 61a, 61b corresponding to the position of the eccentric lock box 11, and the left and right protruding lengths are different. Thus, the opening / closing support leg 3 is supported by the inner wall surfaces 61a and 61b. As a result, the lock box 11 can be supported with high accuracy and certainty on both inner wall surfaces 61a and 61b of the door 61, and the workability can be improved even in the mounting structure of the lock box 11 that is mounted with the lock box 11 eccentric. it can. Moreover, it becomes possible to improve the attachment precision of the lock box 11 with respect to a door.

  Further, since the open / close support leg 3 always contacts the inner wall surfaces 61a and 61b at the outer surfaces 71a and 73a on the opening leg side, it does not make point contact with both inner wall surfaces 61a and 61b, and stress is applied to both inner wall surfaces 61a and 61b. Concentration does not occur. Thereby, the deformation | transformation of the door inner wall surfaces 61a and 61b at the time of supporting the lock box 11 can be prevented.

Next, a first modification of the lock box positioning mechanism according to the present invention will be described.
FIG. 6 is an exploded perspective view showing a first modification of the lock box positioning mechanism according to the present invention, and FIG. 7 is a plan view in the support state of the positioning mechanism shown in FIG.

In the first modification, the contact members 71A and 73A have bent contact pieces 71Aa and 73Aa parallel to both inner wall surfaces 61a and 61b of the door 61. That is, the contact members 71A and 73A according to the present embodiment are made of L-shaped metal fittings.
Therefore, according to this lock box positioning mechanism, for example, even when the contact members 71A and 73A are formed of plate members, as shown in FIGS. The large bent contact pieces 71Aa and 73Aa can be brought into contact with both inner wall surfaces 61a and 61b, and the stress applied to both inner wall surfaces 61a and 61b can be distributed over a larger area. As a result, the deformation of the door inner wall surfaces 61a and 61b can be more reliably prevented. In addition, according to this modification, since rotation of contact member 71A, 73A can be controlled by bending contact piece part 71Aa, 73Aa, the extension of protrusion 75,75 (refer FIG. 2) can be made unnecessary. .

Next, a second modification of the lock box positioning mechanism according to the present invention will be described.
8 is an exploded perspective view showing a second modification of the lock box positioning mechanism according to the present invention, and FIG. 9 is a cross-sectional view of the positioning mechanism shown in FIG. 8 in a supported state.
In the second modification, the contact members 71B and 73B have bent contact pieces 71Ba and 73Ba parallel to both inner wall surfaces 61a and 61b of the door 61. That is, the contact members 71B and 73B according to the present embodiment are U-shaped members.
Therefore, according to this lock box positioning mechanism, for example, even when the contact members 71B and 73B are formed of plate members, as shown in FIG. 8, a bent contact piece larger than the end surface of the plate material. The portions 71Ba and 73Ba can be brought into contact with the inner wall surfaces 61a and 61b, and the stress applied to the inner wall surfaces 61a and 61b can be distributed over a larger area. As a result, the deformation of the door inner wall surfaces 61a and 61b can be more reliably prevented. In this modification, the contact members 71B and 73B are U-shaped, so that the strength of the contact members 71B and 73B themselves can be improved. In addition, according to this modification, since rotation of contact member 71B, 73B can be controlled by bending contact piece part 71Ba, 73Ba, the addition of protrusion 75, 75 (refer FIG. 2) can be made unnecessary. .
