Description

Technical Field

[0001] The present invention relates to the technical field of door devices installed in indoor spaces of buildings such as buildings.

Background Art

[0002] Generally, partition panels are provided to partition indoor spaces of buildings such as buildings. Among such partition panels, when the indoor space is, for example, an office, there is a panel provided to partition between a business room where people perform work, meetings and other operations, and a machine room (equipment room) that accommodates equipment such as air-conditioning equipment. In such partition panels, in order to perform work such as maintenance of equipment arranged in the machine room, the panel body constituting the partition panel (if there are a plurality of such panel bodies, part or all of the panel bodies) is configured as an openable / closable door panel body. However, configuring such an openable / closable door panel body to allow anyone to freely open and close it is not preferable from the viewpoint of management. Therefore, in such cases, it is required to provide a locking device on the openable / closable door panel body, and manage such that only an administrator holding a key can open and close the door panel body. Accordingly, providing a locking device on such a door panel body is known (see, for example, Patent Document 1).

Summary of the Invention

Problem to be Solved by the Invention

[0004] However, in the conventional method of attaching the aforementioned locking device to a door, the tip of the lock body, where the keyhole is formed, is fitted into a keyhole drilled in the surface plate of the door, and the surface plate is then clamped from both sides by the locking device. In this case, the part that protrudes from the surface plate is large in diameter and bulges out conspicuously, impairing visibility. Therefore, it has been proposed that the locking device be mounted via a mounting member provided inside the door panel, so that only the lock tip with the keyhole is exposed from the surface plate. However, in this case, only the keyhole and the lock tip are visible from the surface plate, but mounting errors inevitably occur when attaching the mounting member to the door panel and attaching the locking device to the mounting member. As a result, the lockhole and the lock tip are mounted in a misaligned state, resulting in problems such as inferior design and appearance, and these are the issues that the present invention aims to solve. [Means for solving the problem]

[0005] The present invention was created in view of the above circumstances and with the aim of solving these problems, and the invention of claim 1 is a door device in which a door panel body having front and back plates that can be opened and closed is provided with a locking device that locks and unlocks the door panel body by turning a key inserted into a keyhole, and the locking device comprises a lock body that is attached to the door panel body and a lock tip that extends from the front edge of the lock body body and is provided with a keyhole, wherein the locking device is attached to the door panel body by fastening the lock body to a mounting bracket provided on the door panel body, and a keyhole provided on the front plate of the door panel body into which the lock tip is inserted is exposed together with the lock tip when the locking device is attached to the door panel body, and a position adjustment means is provided between the mounting bracket and the lock body body for adjusting the mounting position of the lock body body with respect to the mounting bracket in the vertical and horizontal directions to align the keyhole and the lock tip. The invention of claim 2 is a door device according to claim 1, wherein the mounting bracket comprises a mounting piece located between front and back plates and to which the lock body is attached from the back side via screws, and the position adjustment means comprises a position adjustment member interposed in an overlapping manner between the lock body and the mounting piece, the position adjustment member being mounted to the mounting piece so as to be position adjustable in one of the vertical or horizontal directions, and mounted to the lock body so as to be position adjustable in the other of the vertical or horizontal directions. The invention of claim 3 is a door device according to claim 2, characterized in that the position adjustment member comprises two plate-like bodies, a first adjustment plate on the mounting piece side and a second adjustment plate on the lock body side, the second adjustment plate is fixed to the lock body with screws and is also fixed to the mounting piece together with the first adjustment plate, and the screw fixing of the first and second adjustment plates and the mounting piece is such that the position of the first adjustment plate and the mounting piece is adjusted in one of the vertical and horizontal directions by guiding the first adjustment plate and the mounting piece with a first convex portion formed on one of the first adjustment plate and the mounting piece into a first guide elongated hole formed on the other which is elongated in one of the vertical and horizontal directions, and the position of the first adjustment plate and the second adjustment plate is adjusted in the other of the vertical and horizontal directions by guiding the first adjustment plate and the second adjustment plate with a second convex portion formed on one of the first adjustment plate and the second adjustment plate into a second guide elongated hole formed on the other which is elongated in the other of the vertical and horizontal directions. The invention of claim 4 is a door device according to claim 2, characterized in that the position adjustment member is made of a single plate-shaped adjustment plate, the adjustment plate is fixed with screws together with the lock body and the mounting piece, and the screw fixing of the adjustment plate, lock body and mounting piece is characterized in that the position of the mounting piece and the adjustment plate is adjusted in one of the vertical and horizontal directions by a first convex portion formed on one of the mounting piece and the adjustment plate being guided by a first guide elongated hole formed on the other which is long in one of the vertical and horizontal directions, and the position of the adjustment plate and the lock body is adjusted in the other of the vertical and horizontal directions by a second convex portion formed on one of the adjustment plate and the lock body being guided by a second guide elongated hole formed on the other which is long in the other of the vertical and horizontal directions. The invention of claim 5 is a door device according to claim 3 or 4, characterized in that the first and second convex portions are formed by burring screw holes for screw fixing. [Effects of the Invention]

[0006] By adopting the invention of claim 1, when the keyhole provided in the surface plate of the door panel is exposed together with the tip of the lock when the lock device is attached to the door panel via a mounting bracket attached to the door panel, the position adjustment means provided between the mounting bracket and the lock body allows for easy adjustment of the vertical and horizontal position of the tip of the lock relative to the keyhole. As a result, misaligned mounting of the tip of the lock is avoided, and the appearance is not compromised. By adopting the invention of claim 2, a position adjustment means is interposed in an overlapping manner between the lock body portion, which is attached to the mounting piece portion of the mounting bracket via screws, and the mounting piece portion. As a result of the position adjustment member constituting the position adjustment means being attached to the mounting piece portion so as to be position-adjustable in one of the vertical or horizontal directions, and attached to the lock body portion so as to be position-adjustable in the other of the vertical or horizontal directions, the position adjustment means can be constructed simply by using the position adjustment member. By adopting the invention of claim 3, the position adjustment member is configured to include a first and a second adjustment plate, in which case the second adjustment plate is screw-fixed to the lock body and also screw-fixed to the mounting piece together with the first adjustment plate. In this case, the screw fixing of the first adjustment plate and the mounting piece is performed with the position adjusted in one of the vertical and horizontal directions by guiding a first convex portion formed on one of the first adjustment plate or the mounting piece into a first guide elongated hole formed on the other that is longer in one of the vertical or horizontal directions. Similarly, the screw fixing of the first adjustment plate and the second adjustment plate is performed with the position adjusted in the other of the vertical and horizontal directions by guiding a second convex portion formed on one of the first or second adjustment plate into a second guide elongated hole formed on the other that is longer in the other of the vertical or horizontal directions. As a result, vertical and horizontal position adjustment can be easily performed using the first and second adjustment plates. By implementing the invention of claim 4, when the position adjustment member is constructed from a single plate-shaped adjustment plate, both the lock body and the mounting piece are fixed to the adjustment plate with screws. However, by fixing the mounting piece and the adjustment plate with screws while guiding a first convex portion formed on one of the mounting piece and the adjustment plate into a first guide slot formed on the other that is elongated in one of the vertical or horizontal directions, the screw fixing is performed while the position adjustment is performed in one of the vertical or horizontal directions. Similarly, by fixing the adjustment plate and the lock body with screws while guiding a second convex portion formed on one of the adjustment plate and the lock body into a second guide slot formed on the other that is elongated in the other of the vertical or horizontal directions, the screw fixing is performed while the position adjustment is performed in the other of the vertical or horizontal directions. As a result, vertical and horizontal position adjustment can be easily performed using a single adjustment plate. By adopting the invention of claim 5, the first and second convex portions are formed by burring screw holes for screw fixing, enabling them to be used for multiple purposes. As a result, there is no need to form separate first and second convex portions, simplifying the structure and improving workability. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0008] The embodiments of the present invention will now be described based on the drawings. In the drawings, 1 is a partition panel that divides the interior space into an office (staff room) R and a machine room (storage room) M, and the partition panel 1 is constructed by connecting two door panel bodies 2, 2a in a continuous manner in the left-right direction. Both of these door panel bodies 2, 2a are constructed to be able to be opened towards the office R side, and are configured as double-opening doors that are pivotally supported via hinges 3a on the left and right structural support columns (partition columns) 3, which are structural members. The door panel bodies 2 and 2a are framed around all four sides by horizontal frame members 4 and 5 on the top and bottom sides, and vertical frame members 6 and 7 on the leading and trailing ends on the left and right sides. Front and back panels 8 and 9 are provided on the front and back sides of the framed structure, on the office R side and the machine room M side, respectively. Regarding the front panel 8, considering visibility from the office R side, the entire door panel body 2 is decorated with the same design or the same concept (for example, a wood grain forest pattern).

[0009] One of the door panel bodies 2, 2a (the one on the left in Figure 2) 2 is provided with a locking device 10 positioned in the inner space S of the corner between the lower horizontal frame material 5 and the door edge side vertical frame material 6. The locking device 10 is a general-purpose cylinder lock and comprises a rectangular prism-shaped lock body 10a in which a cylinder lock mechanism (not shown) is housed, and a lock tip 10b that extends cylindrically from the leading edge 10aa of the lock body 10a, having a smaller width (smaller diameter) than the lock body 10a. The tip of the lock 10b is provided with a keyhole 10c at its edge. By turning the key K inserted into the keyhole 10c, the tip of the lock 10b rotates, causing the latch 10d on the lock body 10a to swing, which engages and disengages with the latch 11 on the door edge end of the other door panel 2a. This allows the locking and unlocking of the locking device 10. Incidentally, the key K used in this case is a general-purpose, wide, plate-shaped key, and is configured as a master key.

[0010] A mounting bracket 12 for attaching the locking device 10 is provided at the corner between the lower horizontal frame member 5 and the door-side vertical frame member 6. The mounting bracket 12 is composed of a first piece 12a on the door-side, whose L-shaped bent tip abuts against or closely faces the front plate 8; a second piece 12b on the door-end, which abuts against or closely faces the back plate 9; and a mounting piece 12c that connects these first and second pieces 12a and 12b. The first piece 12a is attached and fixed (fastened) to the door-end side projection surface 6a of the door-end vertical frame member 6 with which it abuts via screws 12d. Incidentally, the mounting bracket 12 may, of course, be configured such that the bending directions of the first and second pieces 12a and 12b are reversed.

[0011] In a state where the mounting bracket 12 is attached to the vertical frame member 6 on the door end side as described above, the mounting piece portion 12c is positioned at the front-rear intermediate portion between the front and back surface plates 8 and 9, and the mounting piece portion 12c is provided with a through-hole 12e for allowing the lock main body portion 10a to penetrate therethrough. Then, in the lock device 10, in a state where the lock main body portion 10a penetrates the through-hole 12e, a mounting arm portion 10e provided on the lock main body portion 10a is attached and fixed to the mounting piece portion 12c. However, when the lock main body portion 10a is directly attached to the mounting piece portion 12c, there is a possibility that misalignment occurs between the lock tip portion 10b and the key hole 8a due to errors such as mounting errors and processing errors, resulting in an eccentric double circle state of the lock tip portion 10b and the key hole 8a, which leads to poor visibility. Therefore, in the present embodiment, between the mounting bracket 12 and the lock main body portion 10a, specifically between the mounting piece portion 12c and the mounting arm portion 10e of the lock main body portion 10a, there is provided a position adjusting means X for adjusting the position of the lock main body portion 10a in the vertical and horizontal directions (vertical and horizontal directions) to adjust (adjust, correct, rectify) the misalignment between the lock tip portion 10b and the key hole 8a.

[0012] First, the position adjusting means X employed in the present embodiment is configured by using two plate-shaped bodies serving as position adjusting members, which consist of a first adjusting plate member 13 on the mounting bracket 12 side and a second adjusting plate member 14 on the lock main body portion 10a side, and these first and second adjusting plate members 13 and 14 are attached in an overlapping (laminated) state between the mounting piece portion 12c and the mounting arm portion 10e.

[0013] In this case, the first adjusting plate member 13 is attached and fixed to the mounting piece portion 12c via a screw 13a, and the mounting piece portion 12c is formed with a screw screwing portion 12f for the screw portion of the screw 13a to screw into. In this case, the screw screwing portion 12f is formed by burring from the front surface side so as to become a first convex portion 12f protruding toward the back surface side (the first adjusting plate member 13 side). Furthermore, the first adjustment plate material 13 has a first screw hole 13b through which a screw 13a passes, and this first screw hole 13b is an elongated hole that is long in the lateral direction (left-right direction), forming the first guide hole 13b. When the first adjustment plate material 13 comes into contact with (butts against) the footing piece 12c from the back side, the first convex portion 12f is fitted in so as to be movable in the lateral direction.

[0014] With this configuration, the first adjustment plate 13 is assembled to the mounting piece 13c such that the first convex portion 12f is fitted into the first guide hole 13b so as to be movable laterally. This allows the first adjustment plate 13 to be positioned laterally relative to the mounting piece 12c, and it can be attached and fixed to the mounting piece 12c via screws 13a once its laterally positioned position is achieved. It should be noted that, in order to fasten the first adjustment plate 13 to the mounting piece 12c so as to be able to adjust its position laterally, the opposite configuration is also possible, in which a first guide hole that is elongated laterally is formed on the mounting piece 12c side and a first convex portion is formed on the first adjustment plate 13 side.

[0015] On the other hand, the second adjustment plate 14 is attached and fixed to the first adjustment plate 13 via screws 14a, and the first adjustment plate 13 has a screw threading portion 13c into which the threaded portion of the screws 14a is screwed. In this case, the screw threading portion 13c is formed in such a state that it becomes a second convex portion 13c that protrudes to the back side by burring from the front side. In contrast, the second adjustment plate 14 is attached and fixed to the lock body 10a by screwing a screw 10f inserted from the mounting arm 10e provided on the lock body 10a into a screw hole 14b formed in the second adjustment plate 14. Furthermore, the second adjustment plate 14 has a screw hole 14c through which the screw 14a passes to attach and fix the second adjustment plate 14 to the first adjustment plate 13. This screw hole 14c is an elongated hole in the vertical direction and constitutes a second guide hole 14c into which the second convex portion 13c provided on the first adjustment plate 13 is fitted to move freely in the vertical direction.

[0016] With this configuration, the second adjustment plate 14 is assembled to the first adjustment plate 13 with the first convex portion 13c fitted into the second guide hole 14c so as to be movable in the vertical direction. This allows the second adjustment plate 14 to be vertically adjustable relative to the first adjustment plate 13 which is attached and fixed to the mounting piece 12c, and the second adjustment plate 14 is attached and fixed to the first adjustment plate 13 via screws 14a once the vertical positioning is achieved. Incidentally, the first and second adjustment plates 13 and 14 have through holes 13d and 14d formed therein for the lock body 10a to pass through in a loosely fitted manner. In this case, the through hole 14d formed in the second adjustment plate 14 is set to a size that allows the lock body 10a to just loosely fit (pass through), while the through hole 13d formed in the first adjustment plate 13 is long in the vertical direction and is set to allow the threaded portions of the upper and lower screws 10f used to fasten the lock body 10a to the second adjustment plate 14 to pass through as well. Furthermore, the through hole 12e formed in the mounting piece 12c is also long in the vertical direction and is set to allow the threaded portions of the screws 10f to pass through as well. Furthermore, the mounting piece 12c has a through hole 12g through which a screw hole 14a for fastening the second adjustment plate 14 to the first adjustment plate 13 passes.

[0017] Then, with the position adjustment means X configured in this way, the lock body 10a is attached to the mounting piece 12c. As an example of the procedure in this case, first, the mounting bracket 12 is attached and fixed to the cuboid n surface of the door edge side vertical frame material 6 via screws 12d, while the lock body 10a is attached and fixed to the second adjustment plate material 14 via screws 10f. In this state, with the first convex portion 12f provided on the mounting piece 12c fitted into the first guide hole 13b provided on the first adjustment plate 13, the first adjustment plate 13 is brought into contact with the mounting piece 12c from the back side and fastened in a loose (temporarily fastened) state via screws 13a. At the same time, with the second convex portion 13c provided on the first adjustment plate 13 fitted into the second guide hole 14c provided on the second adjustment plate 14, the second adjustment plate 14 is brought into contact with the first adjustment plate 13 from the back side and fastened in a loose (temporarily fastened) state via screws 14a.

[0018] In this way, the lock body 10a is attached to the mounting piece 12c via a position adjustment means X that is movable in the vertical and horizontal directions and is in a loosened state. In this loosened state, the lock body 10a is moved in the vertical and horizontal directions so that the lock tip 10b exposed from the keyhole 8a is concentric with the keyhole 8a. When it is concentric in the horizontal direction, the screw 13a is tightened to fasten the first adjustment plate 13 to the mounting piece 12c. On the other hand, when it is concentric in the vertical direction, the screw 14a is tightened to fasten the second adjustment plate 14 to the first adjustment plate 13. In this way, the lock device 10 can be easily installed in a concentric state with no vertical or horizontal misalignment of the lock tip 10b relative to the keyhole 8a, improving workability.

[0019] In this embodiment, configured as described above, the keyhole 8a provided in the surface plate 8 of the door panel body 2 is exposed along with the lock tip 10b when the lock device 10 is attached via the mounting bracket 12 attached to the door panel body 2. In this case, the position adjustment means X provided between the mounting bracket 12 and the lock body 10a allows for easy adjustment of the vertical and horizontal position of the lock tip 10b relative to the keyhole 8a, thereby avoiding misaligned mounting of the lock tip 10b and preventing any deterioration in appearance.

[0020] Furthermore, in this case, the position adjustment member for constituting the position adjustment means X is composed of two adjustment plates, a first and a second adjustment plate 13 and 14. The first adjustment plate 13 is fixed to the mounting piece 12c via a screw 13a, the second adjustment plate 14 is fixed to the first adjustment plate 13 via a screw 14a, and the lock body 10a is fixed to the second adjustment plate 14 via a screw 10f. In this case, the fixing of the first adjustment plate 13 and the mounting piece 12c via screws 13a is achieved when the first convex portion 12f formed on the mounting piece 12c is fitted into the laterally elongated first guide hole 13b formed on the first adjustment plate 13, thereby adjusting its position laterally. Furthermore, the fixing of the first adjustment plate 13 and the second adjustment plate 14 via screws 14a is achieved when the second convex portion 13c formed on the first adjustment plate 13 fits into the second guide elongated hole 14c formed on the second adjustment plate 14, thereby adjusting the plate in the direction of the body.

[0021] As a result, when the locking device 10 is attached to the door panel body 2, if the lock tip 10b and the keyhole 8a are exposed to each other and no cover material is used to close the keyhole 8a, then if there is a misalignment between the lock tip 10b and the keyhole 8a due to mounting errors, the vertical and horizontal position of the locking device 10 relative to the keyhole 8a can be easily adjusted using the first and second adjustment plates 13 and 14, thus avoiding any loss of visibility. Moreover, in this case, the first and second convex portions 12f and 13c utilize the convex portion of the screw hole formed by burring for screwing in the screws 13a and 14a. Therefore, there is no need to form a dedicated convex portion, and work efficiency can be improved.

[0022] It should be noted that the present invention is not limited to the above-described embodiments. When adjusting the position in the vertical and horizontal directions, the first adjustment plate 13 can be configured to be vertically adjustable relative to the mounting piece 12c, and the second adjustment plate 14 can be configured to be horizontally adjustable relative to the first adjustment plate 13. Furthermore, in the above embodiment, the screws 13a and 14a are inserted from the back side, and the first and second convex portions 12f and 13c are formed on the mounting piece 12c and the first adjustment plate 13. However, it is also possible to configure the device to be fixed with screws from the front side. In this case, when fixing the mounting piece 12c and the first adjustment member 13 with screws, an elongated hole is formed on the mounting piece 12c side in either the vertical or horizontal direction to serve as the first guide hole, while a first convex portion that also serves as a screw hole is formed on the first adjustment plate 13. When fixing the first adjustment plate 13 and the second adjustment plate 14 with screws, an elongated hole is formed on the first adjustment plate 13 side in the other vertical or horizontal direction to serve as the second guide hole, while a second convex portion that also serves as a screw hole is formed on the second adjustment plate 14.

[0023] Furthermore, in the above embodiment, two first and second adjustment plates 13 and 14 were used as position adjustment members to constitute the position adjustment means X, but the second embodiment can also be implemented using one adjustment plate 15. In this configuration, the adjustment plate 15 is sandwiched between the mounting piece 12c and the front edge 10aa of the lock body 10a. In this case, the first convex portion formed on one of the mounting piece 12c and the adjustment plate 15 is guided by a first guide slot formed on the other that is elongated in one of the vertical or horizontal directions, thereby adjusting the position in one of the vertical or horizontal directions. The adjustment plate 15 and the lock body 10a are then fixed with screws in a state where the position in the other vertical or horizontal direction is adjusted by guiding the second convex portion formed on one of the adjustment plate and the lock body 15 by guiding it by a second guide slot formed on the other that is elongated in the other of the vertical or horizontal directions.

[0024] In the second embodiment, as shown in Figure 10, the mounting piece 12c and the adjustment plate 15 are fixed from the back side via screws 15a, and the adjustment plate 15 and the lock body 10a are fixed via screws 10f. Specifically, the mounting piece 12c has a first convex portion 12f formed by burring, which also serves as a screw hole, while the adjustment plate material 15 has a laterally elongated first guide hole 15b formed therein so that the first convex portion 12f can be fitted into it in a way that allows for lateral position adjustment. As a result, the adjustment plate material 15 can be attached to the mounting piece 12c in a way that allows for lateral position adjustment by screwing a screw 15a that passes through from the first guide hole 15b side into the first convex portion 12f while the first convex portion 12f is fitted into the first guide hole 15b. Furthermore, the adjustment plate 15 has a second convex portion 15c formed by burring, which also serves as a screw hole, while the mounting arm portion 10e formed on the lock tip portion 10b has a vertically elongated second guide hole 10g into which the second convex portion 15c is fitted to move vertically. As a result, the lock body portion 10a can be attached to the adjustment plate 15 so as to be vertically adjustable by screwing a screw 10f that passes through from the second guide hole 10g side into the second convex portion 15c.

[0025] In this second embodiment, the lock body 10a is mounted to the adjustment plate 15 so as to be vertically adjustable, and the adjustment plate 15 is mounted to the mounting piece 12c so as to be horizontally adjustable. As a result, the keyhole 8a and the lock tip 10b, which are exposed on the surface side of each other, can be positioned without misalignment, and the appearance can be easily maintained.
