Description

  The present invention relates to a joinery in which a heat insulating material is provided between surface layer materials to form a face material.

  Conventionally, for the purpose of improving heat insulating properties and dew proofing properties, various fittings in which a heat insulating material is disposed inside a face material have been provided. The face material is formed by, for example, disposing a heat insulating material inside an aggregate configured in a rectangular frame shape, and further disposing a surface layer material such as a steel plate on both surfaces of the frame of the aggregate. (For example, refer to Patent Document 1).

  When a face material is used as a door, a lock case is provided at a portion on the door end side, and a handle is provided on the surface of the door. The lock case incorporates a lock that keeps the door closed by engaging with the opening frame, and is accommodated in an accommodating portion provided between the surface layers. The handle has a function of releasing the lock of the lock case from the outside of the door, and is provided on both surfaces of the face material located on the door end side (see, for example, Patent Document 2).

JP-A-7-91152 JP 2006-274623 A

  By the way, various types of handles are provided for the doors. However, in recent years, an operation unit for the handle is disposed on the surface of the face material via a pedestal, and the operation of the operation unit is displaced with respect to the pedestal. For example, a configuration in which the lock of the lock case is released by bringing the operation unit closer to or away from the face material is also provided. In a joinery equipped with this type of handle, the unlocking operation is easier compared to conventional ones that rotate the operating part of the handle, so even if you have a load on both hands, for example. It is advantageous in terms of convenience, such as being able to open the door.

However, when the operation unit is operated, the operation force is applied to the surface material of the face material via the pedestal part of the handle. In particular, when the pedestal portion of the handle and the position of the operation portion for operating the handle are offset with respect to the face material, the pedestal portion of the handle is in contact with the surface layer material when the operation portion is operated. In this state, the operating force applied to the surface material concentrates, and the situation becomes more severe in terms of strength.

  Here, when the size of the pedestal portion of the handle is larger than that of the lock case, the pedestal portion of the handle that protrudes from the lock case can sandwich the heat insulating material from both sides through the surface layer material. It becomes possible to receive the operating force applied to the surface layer material with the heat insulating material when operated. On the other hand, in the case where the lock case is configured to be larger than the pedestal portion of the handle, the accommodating portion for accommodating the lock case also becomes large, and it becomes difficult to sandwich the heat insulating material by the pedestal portion. As a result, the operating force when operating the operating part of the handle cannot be received by the heat insulating material, and the surface layer material is deformed, and there is a risk of causing a problem such as the pedestal of the handle being lifted from the surface material. is there.

  In view of the above circumstances, an object of the present invention is to provide a joinery that can suppress the deformation of the surface material when the operation portion of the handle is operated regardless of the size of the lock case.

In order to achieve the above object, a joinery according to the present invention is provided with a handle having an operation part at a position offset with respect to a pedestal part on the surface of a face member provided with a heat insulating material between surface layer materials, A fitting that disposes the lock on the opening frame by disposing a lock case in an accommodating portion provided between the surface layer materials and releasing the lock of the lock case by operating the operation portion with respect to the pedestal portion. A reinforcing portion is provided between the inner surface of the surface layer material provided with the handle and the lock case in a state of being thermally in non-contact with the other surface layer material, and the reinforcing portion includes the handle A cover portion disposed between the inner surface of the surface layer material provided with the outer surface of the lock case, and the edge of the cover portion that is bent at a substantially right angle from the edge located on the door tip side, A connecting piece supported by an aggregate located on the side; A support that is bent at a substantially right angle in the same direction as the connecting piece from the edge located on the suspending side of the cover, and supported by a contact surface along the direction of finding the heat insulating material through the bent end. The one part is formed integrally with a metal plate-like member .

  According to the present invention, the operating force of the operating portion applied to the surface layer material via the pedestal portion is received by the lock case by the reinforcing portion interposed between the inner surface of the surface layer material provided with the handle and the lock case. Can do. Moreover, since the reinforcing portion is not thermally in contact with the other surface layer material, there is no possibility of affecting the heat insulating property of the face material.

Each of the accommodating portions 26A and 26B is set to have a large size in the vertical and horizontal directions and a size in the thickness direction with respect to the lock cases 30A and 30B to be accommodated.

  As shown in FIGS. 6 and 7, the handles 40A and 40B include a pair of upper and lower pedestal portions 41Aa, 41Ab, 41Ba, and 41Bb whose vertical and horizontal dimensions are smaller than those of the lock cases 30A and 30B, and these pedestal portions 41Aa. , 41Ab, 41Ba, 41Bb and operating parts 42A, 42B arranged to be movable with respect to the pedestal parts 41Aa, 41Ab, 41Ba, 41Bb, and the pedestal parts 41Aa, 41Ab, 41Ba, 41Bb. On the other hand, when the operation units 42A and 42B are moved from the normal position to the release position, the latch output shaft 43 is released in the upper pedestal portion (hereinafter referred to as “upper pedestal portions 41Aa and 41Ba” for distinction). Is. In the first embodiment, the pull handle 40A is disposed at a portion located outside the room with the face material 20 closed in the opening frame 10, and the push handle 40B is disposed at a portion located indoors. .

  The pull handle 40A releases the latch output shaft 43 when the pedestal portions 41Aa and 41Ab are operated so as to separate the operation portion 42A from the face material 20. The push handle 40B is configured to release the latch output shaft 43 when the pedestal portions 41Ba and 41Bb are operated so as to bring the operation portion 42B closer to the face material 20. As is apparent from FIG. 1, in the first embodiment, the operation unit 42B of the push handle 40B is disposed at a position offset from the pedestal parts 41Ba and 41Bb.

  Also, as shown in FIGS. 6 and 7, the upper pedestal portion 41Aa of the pull handle 40A and the lower pedestal portion of the pull handle 40A (hereinafter referred to as “lower pedestal portion 41Ab” for distinction) are respectively provided in the key cylinder 44. The thumb pedestal 41Ba of the push handle 40B and the lower pedestal portion of the push handle 40B (hereinafter referred to as “lower pedestal portion 41Bb” for distinction) are provided with thumb turns 45, respectively. The key cylinder 44 can rotate only when a key (not shown) is inserted. When the key cylinder 44 is rotated, a dead operation part (not shown) is locked and unlocked in each of the pedestal parts 41Aa and 41Ab. Although not clearly shown in the drawing, the thumb turn 45 is for locking and unlocking a dead operation portion (not shown) in each of the pedestal portions 41Ba and 41Bb when rotating around the horizontal axis.

  As shown in FIGS. 2, 6, and 7, the push handle 40B and the pull handle 40A are arranged such that the upper pedestal portions 41Aa and 41Ba are arranged at portions corresponding to the upper lock case 30A, and the lower pedestal portions 41Ab and 41Bb are arranged. It is attached to the face material 20 via the surface layer members 23 and 24 in a state where it is disposed at a portion corresponding to the lower lock case 30B. Although not shown in the drawing, the latch output shaft 43 of the push handle 40B and the latch output shaft 43 of the pull handle 40A are linked to a latch lock mechanism (not shown) of the upper lock case 30A, respectively. When the is released, the latch bolt 32 in the engaged state can be brought into the non-engaged state. The dead operation part (not shown) of the push handle 40B and the dead operation part (not shown) of the pull handle 40A are linked to the corresponding dead lock mechanisms (not shown) of the lock cases 30A and 30B, respectively. When at least one of the locking and unlocking operations is performed, it is possible to cause the dead bolt 31 to protrude from the front surface of the lock cases 30A and 30B.

  In the joinery configured as described above, in a normal state, the latch bolt 32 protrudes from the door end surface of the face member 20 and is in a state in which the backward movement is prevented. Therefore, when the face material 20 is disposed in a closed state with respect to the opening frame 10 and the latch bolt 32 is engaged with the receiving seat 14 (see FIG. 4) provided on the vertical frame 13 of the opening frame 10, the opening is obtained. The face material 20 can be kept closed with respect to the frame 10.

  From this state, the operation part 42B of the push handle 40B is operated so as to approach the face material 20 with respect to the pedestal parts 41Ba and 41Bb, or the operation part 42A is operated so as to be separated from the face material 20 with respect to the pedestal parts 41Aa and 41Ab. Then, the latch bolt 32 is brought into a non-engagement state. As a result, when the face material 20 is moved to the outdoor side with respect to the opening frame 10, the latch bolt 32 that is in contact with the seat 14 of the opening frame 10 is degenerated and moved with respect to the opening frame 10. The material 20 can be released. Note that the dead bolt 31 is applied to the door end surface of the face member 20 by operating the thumb turn 45 from the indoor side or by operating the key cylinder 44 with a key (not shown) inserted from the outdoor side. , The face material 20 can be locked with respect to the opening frame 10, and the face material 20 keeps the opening frame 10 closed even if the push handle 40B or the pull handle 40A is operated thereafter. Is done.

  Here, when the operation part 42B of the push handle 40B is operated so as to approach the face material 20 with respect to the pedestal parts 41Ba and 41Bb, the operating force is applied to the surface layer material 24 of the face material 20. In particular, since the push handle 40B having a configuration in which the positions of the base parts 41Ba and 41Bb and the position of the operation part 42B are offset to the left and right with respect to the face material 20 is applied, the base when the operation part 42B is operated. The portions 41Ba and 41Bb are likely to be in a single-contact state with respect to the surface layer material 24, and there is a possibility that an operating force is concentrated on the surface layer material 24.

  Therefore, in the face material 20 of the first embodiment, as shown in FIG. 1, between the inner surface of the surface layer material 24 located on the indoor side where the push handle 40B is provided and the side surface of the upper lock case 30A, In addition, a reinforcing portion 22a is interposed between the inner surface of the surface layer member 24 located on the indoor side and the side surface of the lower lock case 30B. These reinforcing portions 22a are plate-like portions formed integrally with the heat insulating material 22 disposed between the surface layer materials 23 and 24, respectively. The plate thickness of the reinforcing portion 22a is formed to a dimension that can fill the gap between the inner surface of the surface layer member 24 and the outer surfaces of the lock cases 30A and 30B. A window hole 22b is formed in a portion where the latch output shaft 43 for transmitting the operation of the push handle 40B to the lock case 30A and a dead operation portion (not shown) are provided.

  According to the joinery configured as described above, since the reinforcing portion 22a is interposed between the inner surface of the surface layer member 24 provided with the push handle 40B and the outer surface of the lock case 30A, 30B, the pedestal portions 41Ba, 41Bb are provided. The operation force of the push handle 40B applied to the surface layer member 24 can be received by the lock cases 30A and 30B. Therefore, as in the first embodiment, the outer surfaces of the lock cases 30A and 30B are configured to be larger than the pedestals 41Aa, 41Ab, 41Ba and 41Bb of the handles 40A and 40B, and the pedestals 41Ba and 41Bb of the push handle 40B and the pull handle Even if it is difficult to sandwich the heat insulating material 22 between the pedestal portions 41Aa and 41Ab of 40A, it becomes possible to suppress the deformation of the surface layer material 24 when the push handle 40B is operated, and the push handle 40B. There is no fear that the pedestal portions 41Ba and 41Bb will be raised from the surface material 24. In addition, the reinforcing portion 22a is not in thermal contact with the surface layer material 23 located outside the outdoor portion, and the reinforcing portion 22a does not transfer heat between the surface layer materials 23 and 24. There is no fear of affecting the heat insulation of 20.

Accordingly, the outer surfaces of the lock cases 30A and 30B are configured to be larger than the pedestal portions 41Aa, 41Ab, 41Ba and 41Bb of the handles 40A and 40B, and the pedestal portions 41Ba and 41Bb of the push handle 40B and the pedestal portions 41Aa and 41Ab of the pull handle 40A. Even if it is a joinery in which it is difficult to sandwich the heat insulating material 22 between the two, it is possible to suppress the deformation of the surface layer material 24 when the push handle 40B is operated, and the pedestals 41Ba and 41Bb of the push handle 40B are formed on the surface layer. There is no risk of incurring problems such as lifting from the material 24. Moreover, since the reinforcing portion 222 is not in thermal contact with the surface layer material 23 located on the outdoor side and the reinforcing portion 222 does not transfer heat between the surface layer materials 23 and 24, the face material There is no fear of affecting the heat insulation of 20. Furthermore, since the periphery of the lock cases 30A and 30B is covered with the reinforcing portion 222, it is possible to increase the mounting rigidity of the lock cases 30A and 30B with respect to the face material 20 and the rigidity of the lock cases 30A and 30B themselves.
