[Figure 3] This is a perspective view showing the manual locking device and roller latch provided on the sleeve portion. [Figure 4] This is a perspective view showing the lock receiver and latch receiver provided on the door body. [Figure 5] This diagram shows how the roller latch engages with the latch receiver. [Modes for carrying out the invention]

[0008] Hereinafter, an embodiment of the joinery described herein will be described in detail with reference to the drawings. In the following description, the horizontal direction of the door body 3 and the side panel 4 will be referred to as the left-right direction X. The left-right direction X is the width direction of the door body 3 and the width direction of the side panel 4. In the left-right direction X, one side will be referred to as the X1 side (right side in Figure 1), and the other side as the X2 side (left side in Figure 1).

[0009] As shown in Figures 1 and 2, the joinery 1 of this embodiment comprises a frame 2 fixed to the building, a door body 3 (door body) arranged to open and close within the frame 2, and a side section 4 arranged on the leading edge side of the frame 2. The joinery 1 is installed for the entrance of the building. The joinery 1 can be locked and unlocked by a manual locking device 5 and an electric locking device 6.

[0010] The frame 2 is provided along the four sides of the opening of the building. As shown in Figures 1 and 2, the frame 2 is framed in a rectangle by an upper frame 21 and a lower frame 22 as horizontal frames, a vertical frame 23 positioned on the X1 side in the left-right direction X, and a vertical frame 24 positioned on the X2 side in the left-right direction X. Inside the frame 2, the door body 3 and the side panels 4 are arranged adjacent to each other in the width direction. The door body 3 is positioned on the X1 side in the left-right direction X. The side panels 4 are positioned on the X2 side in the left-right direction X.

[0011] Door body 3 is an entrance door. As it is for entrance use, door body 3 is heavier and has a more substantial feel compared to interior doors. Door body 3 is a hinged door that can be opened and closed by rotating around the pivot axis of a hinge 25 provided on the vertical frame 23 on the X1 side in the left-right direction X. Door body 3 is installed in a so-called outward-opening configuration, rotating outwards from the closed position.

[0012] The door body 3 is formed in a roughly rectangular, plate-like shape that is elongated in the vertical direction. As shown in Figure 2, an exterior handle 26 is attached to the exterior surface of the door body 3. An interior handle 27 is attached to the interior surface of the door body 3. The exterior handle 26 and the interior handle 27 are formed extending in the vertical direction near the leading edge of the door body 3.

[0013] The exterior handle 26 and the interior handle 27 are formed in a roughly U-shape that opens towards the door body 3, and their upper and lower ends are connected to the exterior or interior surface of the door body 3.

[0014] The exterior handle 26 and the interior handle 27 constitute a gripping part that the user (hereinafter referred to as "user") grasps to open and close the door body 3. The user can open and close the door body 3 by grasping the exterior handle 26 or the interior handle 27 and pushing or pulling the door body 3.

[0015] The exterior handle 26 and the interior handle 27 are fixed handles that are fixed to the door body 3 in an immovable state. The exterior handle 26 and the interior handle 27 are fixed to the exterior or interior surface of the door body 3 in an immovable state so that the door body 3 can be opened and closed. The exterior handle 26 and the interior handle 27 are not provided with a mechanism to release the roller latch 7 (latch part). For example, there are conventionally known building components that have a mechanism that allows the latch part to be released by gripping the handle. In contrast, in this embodiment, neither the exterior handle 26 nor the interior handle 27 has a mechanism that releases the latch part by gripping the handle. Therefore, in the building component 1 of this embodiment, even if the user grips the exterior handle 26 or the interior handle 27, the roller latch 7 (latch part) cannot be released.

[0016] As shown in Figure 2, the exterior handle 26 has a vertically extending grab bar 261 (vertical member) and a pair of end support parts 262 that protrude toward the door body 3 from the upper and lower ends of the grab bar 261. The grab bar 261 is gripped when opening and closing the door body 3.

[0017] The interior handle 27, like the exterior handle 26, has a vertically extending grab bar 271 (vertical member) and a pair of end support parts (not shown) that protrude from the upper and lower ends of the grab bar 271 toward the door body 3. The grab bar 271 is gripped when opening and closing the door body 3.

[0018] In this embodiment, the grab bar 261 of the exterior handle 26 and the grab bar 271 of the interior handle 27 are formed in a straight line extending vertically, for example, with a length of 80% to 100% of the vertical length of the door body 3 when viewed from the interior or exterior.

[0019] As shown in FIGS. 1 and 2, the sleeve portion 4 is disposed within the frame body 2 adjacent to the door body 3. When the door body 3 is in the closed position, the sleeve portion 4 is disposed on the leading edge side of the door body 3. When the door body 3 is in the closed position, the sleeve portion 4 is disposed opposite to the end face 3a on the leading edge side of the door body 3.

[0020] The sleeve portion 4 is a sub-door that can be opened and closed by rotating about the rotation axis of the hinge 41 provided on the vertical frame 24 on the X2 side in the left-right direction X. The sleeve portion 4 is attached in a so-called outward-opening manner, rotating from the closed state toward the outdoor side (the front side of the paper surface in FIG. 1). Normally, the sleeve portion 4 is fixed in the closed state and is used in the open state when it is desired to greatly widen the opening within the frame body 2 when loading and unloading large luggage during a move or the like.

[0021] The sleeve portion 4 is provided with two manual locking devices 5, an electric locking device 6, and a roller latch 7 (latch portion). The two manual locking devices 5 are provided in the sleeve portion 4 at vertically spaced positions.

[0022] As shown in FIG. 3, each of the manual locking devices 5 includes a box locking portion 51 having a hook-shaped deadlock portion 511, a cylinder portion 52 having a keyhole 521 formed at its tip, and a thumb turn portion (not shown).

[0023] The box locking portion 51, the cylinder portion 52, and the thumb turn portion (not shown) are provided in the sleeve portion 4. The cylinder portion 52 is provided on the outdoor side of the sleeve portion 4. The thumb turn portion is provided on the indoor side of the sleeve portion 4, although not shown. The box locking portion 51 is shared when locking and unlocking with the manual locking device 5 and when locking and unlocking with the electric locking device 6.

[0024] The deadlock portion 511 is provided so as to be able to project and retract from the end face 4a of the sleeve portion 4 toward the door body 3 side. The deadlock portion 511 is formed in a sickle shape with its tip protruding upward when locked. The deadlock portion 511 can engage with a locking receiver portion 28 (see FIGS. 2 and 4) provided on the end face 3a on the leading edge side of the door body 3.

[0025] The deadbolt hook 511 is configured to be movable between a position where the deadbolt hook 511 protrudes and engages with the lock receiver 28 of the door body 3 to lock it, and a position where the deadbolt hook 511 is retracted and disengaged from the lock receiver 28 to unlock it, when a user opening or closing the door body 3 rotates the keyhole 521 of the cylinder 52 from the outside or rotates the thumbturn (not shown) from the inside. In addition to operating the cylinder 52 or the thumbturn, the door body 3 can also be locked and unlocked by driving the motor (not shown) of the electric locking device 6, which will be described later.

[0026] The electric lock device 6 is installed on the sleeve portion 4, as shown in Figures 1 and 2. The electric lock device 6 comprises an outdoor authentication unit 61, a locking / unlocking drive unit (not shown) having electrical components such as a motor (not shown), and a control unit. The outdoor authentication unit 61 is exposed on the outdoor side of the sleeve portion 4, as shown in Figure 1.

[0027] The outdoor authentication unit 61 authenticates the user by receiving an authentication signal wirelessly when the user presses the authentication button while carrying an authentication device, or when the user presses the authentication button and holds an authentication card key over it. The control unit (not shown) determines the authentication signal transmitted from the outdoor authentication unit 61 of the electric lock device 6 and drives a motor (not shown) if predetermined conditions are met. This operates the deadbolt hook 511 of the box lock unit 51, thereby locking and unlocking the door body 3.

[0028] Furthermore, for example, if the electric locking device 6 malfunctions, the user can insert a key into the keyhole 521 of the cylinder part 52 of the manual locking device 5 and rotate it to move the deadbolt part 511, thereby locking and unlocking the door body 3.

[0029] As shown in Figure 3, the roller latch 7 is positioned between two manual locking devices 5 that are spaced apart vertically at the end of the side section 4 on the door body 3 side.

[0030] The roller latch 7 is a latch that does not interlock with the outdoor handle 26 and the indoor handle 27. In this embodiment, the outdoor handle 26 and the indoor handle 27 are not provided with a mechanism to release the latch. Therefore, because the roller latch 7 is not interlocked with the outdoor handle 26 or the indoor handle 27, when the door body 3 is in the closed position, the outdoor handle 26 or the indoor handle 27 cannot release the roller latch 7. For example, even if a user grips the outdoor handle 26 or the indoor handle 27, they cannot release the roller latch 7.

[0031] The roller latch 7 has a cylindrical roller portion 71 that extends in the vertical direction. The roller portion 71 is rotatable around a rotation axis that extends in the vertical direction. The roller portion 71 is provided at the end face 4a of the sleeve portion 4 in a state biased toward the door body 3 side, and can extend and retract toward the door body 3 side from the end face 4a of the sleeve portion 4.

[0032] When the door body 3 is closed, the roller portion 71 is biased toward the door body 3 and engages with the latch receiving portion 29 (see Figures 2 and 4) provided on the leading edge end face 3a of the door body 3 to maintain the closed state of the door body 3. When a force greater than the force holding the door body 3 is applied to open it, the engagement of the roller portion 71 is released, and the door body 3 can be opened. As shown in Figures 4 and 5, the latch receiving portion 29 is formed as a semicircular recess from the leading edge end face 3a of the door body 3 and extends in the vertical direction.

[0033] To open the door body 3 from the outside, from the state shown in Figure 1, unlock it using the electric lock device 6 or manual lock device 5, and then pull the outside handle 26 towards you. When a force greater than the force holding the door body 3 is applied to the door body 3, the engagement between the roller latch 7 and the latch receiver 29 is released, and the door body 3 can be opened as shown in Figure 2. To close the door body 3, move the door body 3 to the closed position as shown in Figure 5, thereby engaging the roller latch 7 with the latch receiver 29. This allows the door body 3 to be closed. After the door body 3 is closed, it is locked using the electric lock device 6 or manual lock device 5.

[0034] This embodiment provides the following advantages. The door 1 of this embodiment includes an entrance door body 3 to which an exterior handle 26 is attached and which can be opened and closed, a side portion 4 positioned opposite the leading edge end face 3a of the door body 3 when the door body 3 is in the closed position, and a roller latch 7 provided on the side portion 4 that does not interlock with the exterior handle 26.

[0035] As a result, when opening the entrance door 3 located at the entrance of the building, it is not necessary to release the latch using the exterior handle 26, making it easy to open the entrance door 3. Furthermore, since the exterior handle 26 does not have a mechanism that interlocks with the roller latch 7, it can be a fixed handle that is fixed in place on the door 3. Also, since the exterior handle 26 does not have a mechanism that interlocks with the roller latch 7, there is no need to install a mechanism that interlocks with the roller latch 7 inside the door 3, and the exterior handle 26 can be installed at any position and in any shape on the door 3. This improves the freedom of placement and shape of the exterior handle 26, making it possible to create a handle with a high level of design appeal.

[0036] In this embodiment, the door body 3 is held by a roller latch 7 that is not linked to the exterior handle 26. Therefore, since the roller latch 7 engages with and disengages from the latch receiving portion 29 simply by opening and closing the door body 3, the entrance door body 3 can be easily opened and closed with a simple configuration.

[0037] In this embodiment, the exterior handle 26 has a grip bar 261 that extends vertically. This allows the door body 3 to be opened and closed by gripping the vertically extending grip bar 261, making it easy to open and close the entrance door body 3. Furthermore, because it has a vertically extending grip bar 261, the exterior handle 26 can have a clean design, improving its aesthetic appeal.

[0038] This disclosure is not limited to the embodiments described above, and any modifications, improvements, etc., that are effective in achieving the objectives of this disclosure are included.

[0039] For example, the above embodiment is configured with an electric locking device, but it is not limited to this, and it does not have to have an electric locking device.

[0040] Furthermore, in the above embodiment, a door body (door frame) and a side section 4 are provided, and a latch is provided on the side section 4, but the invention is not limited to this. For example, a door body (door frame) and a side section 4 may be provided, and the latch may be provided on the door body (door frame). Alternatively, a door frame and a door body (door frame) may be provided without a side section, and the latch may be provided on the door body (door frame). Alternatively, a door frame and a door body (door frame) may be provided without a side section, and the latch may be provided on the door frame.

[0041] Furthermore, in the above embodiment, the latch portion that does not interlock with the handle is made up of a roller latch 7. However, it is not limited to this. For example, the latch portion may be made up of a magnetic latch. A magnetic latch is a latch that, when the door body (door frame) is closed, holds the door body 3 closed by magnetic force, and when a force greater than the magnetic holding force is applied to the door body 3, the magnetic holding is released and the door body 3 can be opened.

[0042] Furthermore, in the above embodiment, the latch portion that is not linked to the handle is configured to be released by applying force to the door body (door frame body) as in the roller latch 7, but the invention is not limited to this. The latch portion may be configured not to be linked to the handle by not providing a mechanism to release the latch portion on the handle, for example, by providing a latch release button separately from the handle, so that the latch portion is released when the latch release button is pressed.

[0043] Furthermore, in the above embodiment, a sleeve portion 4 is provided, and the opposing portion is made of the sleeve portion 4, but the embodiment is not limited to this. A sleeve portion 4 does not have to be provided. For example, in a configuration without a sleeve portion 4, the opposing portion may be made of the vertical frame of the frame or the wall of the building. In this case, a latch portion may be provided on the vertical frame of the frame or the wall of the building.

[0044] In the above embodiment, the sleeve portion 4, which serves as the opposing part, is a sub-door that can be opened and closed, but the embodiment is not limited to this. The sleeve portion 4, which serves as the opposing part, may be configured to be non-openable or non-openable.

[0045] In the above embodiment, the handle is a handle having a vertical member extending in the vertical direction, but it is not limited to this. For example, the handle may be formed in the shape of a door knob that protrudes from the surface of the door body (door frame), or it may be formed in the shape of a handle that is recessed from the surface of the door body (door frame).
