[0008] An embodiment of the fittings of the present disclosure will be described in detail below with reference to the drawings. In the following description, the lateral direction of the door body 3 and the sleeve portion 4 is referred to as the left-right direction X. The left-right direction X is the width direction of the door body 3 and the sleeve portion 4. In the left-right direction X, one side is referred to as the X1 side (the right side in FIG. 1), and the other side is referred to as the X2 side (the left side in FIG. 1).

[0009] As shown in Figures 1 and 2, the fitting 1 of this embodiment comprises a frame 2 fixed to a building, a door body 3 (door body) arranged so as to be able to be opened and closed within the frame 2, and a sleeve 4 arranged on the door end side of the frame 2. The fitting 1 is installed as an entrance to a building. The fitting 1 can be locked and unlocked using a manual locking device 5 and an electric locking device 6.

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

[0011] The door body 3 is a door for an entrance. The door body 3 is for an entrance and is heavier and feels heavier than door bodies for indoor use. The door body 3 is a swing door that can be opened and closed by rotating around the rotation axis of a hinge 25 provided on a vertical frame 23 on the X1 side in the left-right direction X. The door body 3 is installed in a so-called outward-opening state, which means that it rotates from a closed state toward the outside of the room.

[0012] The door body 3 is formed in the shape of a generally rectangular plate that is long in the vertical direction. As shown in Fig. 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 to extend in the vertical direction near the end of the door tip side of the door body 3.

[0013] The exterior handle 26 and the interior handle 27 are formed in an approximately U-shape with the door body 3 side open, and the upper and lower ends are connected to the exterior or interior surface of the door body 3.

[0014] The outdoor handle 26 and the indoor handle 27 constitute gripping portions that are gripped by a user (hereinafter referred to as "user") who opens or closes the door body 3 to open or close the door body 3. The user can grip the outdoor handle 26 or the indoor handle 27 and push or pull the door body 3 to open or close it.

[0015] The exterior handle 26 and the interior handle 27 are fixed handles that are fixed immovably to the door body 3. The exterior handle 26 and the interior handle 27 are fixed to the exterior or interior surface of the door body 3 immovably relative to the door body 3 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 for releasing the roller latch 7 (latch portion). For example, as a conventionally known technology, there is a fitting that has a mechanism that allows the latch portion to be released by grasping the handle. In contrast, in this embodiment, neither the exterior handle 26 nor the interior handle 27 has a mechanism for releasing the latch portion by grasping the handle. Therefore, in the fitting 1 of this embodiment, the roller latch 7 (latch portion) cannot be released even if a user grasps the exterior handle 26 or the interior handle 27.

[0016] 2, the exterior handle 26 has a grip bar 261 (vertical member) extending in the vertical direction, and a pair of end support portions 262 protruding from the upper and lower ends of the grip bar 261 toward the door body 3. The grip bar 261 is gripped when opening or closing the door body 3.

[0017] Similar to the configuration of the outdoor handle 26, the indoor handle 27 has a grip bar 271 (vertical member) extending in the vertical direction, and a pair of end support portions (not shown) protruding from the upper and lower ends of the grip bar 271 toward the door body 3. The grip bar 271 is gripped when opening or closing the door body 3.

[0018] In this embodiment, the grip bar 261 of the outdoor handle 26 and the grip bar 271 of the indoor handle 27 are formed in a straight line extending vertically, for example, with a length that is 80% to 100% of the vertical length of the door body 3, when viewed from inside or outside the room.

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

[0020] The sleeve 4 is a sub-door that can be opened and closed by rotating around the rotation axis of a hinge 41 provided on the vertical frame 24 on the X2 side in the left-right direction X. The sleeve 4 is installed in a so-called outward-opening manner, rotating from a closed state toward the outside of the room (the front side of the paper in Figure 1). The sleeve 4 is normally fixed in a closed state, and is used in an open state when it is necessary to widen the opening inside the frame body 2 to load or unload large items, such as when moving.

[0021] Two manual locking devices 5, an electric locking device 6, and a roller latch 7 (latch portion) are provided on the sleeve portion 4. The two manual locking devices 5 are provided on the sleeve portion 4, spaced apart from each other above and below.

[0022] As shown in Figure 3, each manual locking device 5 comprises a box lock portion 51 having a hook-shaped dead sickle portion 511, a cylinder portion 52 having a keyhole 521 formed at the tip, and a thumb turn portion (not shown).

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

[0024] The dead sickle portion 511 is provided so as to be able to protrude from the end surface 4a of the sleeve portion 4 toward the door body 3. The dead sickle portion 511 is formed in a sickle shape with the tip protruding upward when locked. The dead sickle portion 511 is able to engage with the lock receiving portion 28 (see Figures 2 and 4) provided on the end surface 3a on the door leading side of the door body 3.

[0025] The dead sickle portion 511 is configured to be movable between a position where the dead sickle portion 511 projects and engages with the lock receiving portion 28 of the door body 3 to lock it, and a position where the dead sickle portion 511 is retracted and disengaged from the lock receiving portion 28 to unlock it, by the user opening or closing the door body 3 rotating the keyhole 521 of the cylinder portion 52 from the outside of the room, or by rotating the thumb turn portion (not shown) from the inside of the room. In addition to operating the cylinder portion 52 or the thumb turn portion, the dead sickle portion 511 can also lock and unlock the door body 3 by driving a motor (not shown) of the electric lock device 6, which will be described later.

[0026] As shown in Figures 1 and 2, the electric locking device 6 is provided in the sleeve section 4. The electric locking device 6 includes 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 arranged exposed on the outdoor side of the sleeve section 4 as shown in Figure 1.

[0027] The outdoor authentication unit 61 wirelessly receives an authentication signal to authenticate the user when the user presses the authentication button while carrying a portable authentication device, or when the user presses the authentication button and holds up an authentication card key. A control unit (not shown) judges 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 dead sickle part 511 of the box lock unit 51, locking and unlocking the door body 3.

[0028] Also, for example, if the electric locking device 6 breaks down, the user can insert a key into the keyhole 521 of the cylinder portion 52 of the manual locking device 5 and rotate it to move the dead sickle portion 511 and lock or unlock the door body 3.

[0029] As shown in FIG. 3, the roller latch 7 is disposed at the end of the sleeve 4 on the door body 3 side between two manual locking devices 5 that are spaced apart in the vertical direction.

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

[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 also extends in the vertical direction. The roller portion 71 is provided on the end surface 4a of the sleeve portion 4 in a state where it is biased toward the door main body 3, and can extend and retract from the end surface 4a of the sleeve portion 4 toward the door main body 3.

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

[0033] To open the door body 3 from the outside of the room, after unlocking it using the electric locking device 6 or the manual locking device 5 from the state shown in FIG. 1, the outside handle 26 is pulled toward you. When a force greater than the force holding the door body 3 is applied to the door body 3, the roller latch 7 and the latch receiver 29 are disengaged, allowing the door body 3 to be opened as shown in FIG. 2. To close the door body 3, as shown in FIG. 5, the door body 3 is moved to the closed position, causing the roller latch 7 to engage 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 locking device 6 or the manual locking device 5.

[0034] According to this embodiment, the following effects are achieved: The fitting 1 of this embodiment comprises an entrance door body 3 to which an exterior handle 26 is attached and which can be opened and closed, a sleeve 4 that is arranged opposite the leading end face 3a of the door body 3 when the door body 3 is in the closed position, and a roller latch 7 that is provided on the sleeve 4 and does not move in conjunction with the exterior handle 26.

[0035] As a result, when opening the entrance door body 3 located at the entrance of a building, there is no need to release the latch with the exterior handle 26, making it easy to open the entrance door body 3. Furthermore, because the exterior handle 26 is not provided with a mechanism that interlocks with the roller latch 7, it can be a fixed handle that is fixed in a state that it does not move relative to the door body 3. Furthermore, because the exterior handle 26 is not provided with a mechanism that interlocks with the roller latch 7, there is no need to provide a mechanism that interlocks with the roller latch 7 inside the door body 3, and the exterior handle 26 can be provided in any position and in any shape on the door body 3. This increases the degree of freedom in the placement and shape of the exterior handle 26, making it possible to create a handle with a high level of design.

[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, the roller latch 7 is engaged with and disengaged from the latch receiving portion 29 simply by opening or closing the door body 3, making it possible to easily open and close the entrance door body 3 with a simple configuration.

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

[0038] The present disclosure is not limited to the above-described embodiments, and includes modifications, improvements, etc. within the scope of achieving the object of the present disclosure.

[0039] For example, in the above embodiment, the configuration is such that an electric lock device is provided, but this is not limiting, and the electric lock device may not be provided.

[0040] In the above embodiment, the door body (door body) and the sleeve 4 are provided, and the latch unit is provided on the sleeve 4, but this is not limiting. For example, the door body (door body) and the sleeve 4 may be provided, and the latch unit may be provided on the door body (door body). Also, without providing a sleeve, only the door frame and door body (door body) may be provided, and the latch unit may be provided on the door body (door body). Also, without providing a sleeve, only the door frame and door body (door body) may be provided, and the latch unit may be provided on the door frame.

[0041] In the above embodiment, the latch unit that is not linked to the handle is configured as a roller latch 7. However, this is not limiting. For example, the latch unit may be configured as a magnetic latch. A magnetic latch is a latch that uses magnetic force to hold the door body 3 closed when the door body (door frame) is closed, and when a force greater than the magnetic holding force is applied to the door body 3, the magnetic holding force is released, allowing the door body 3 to be opened.

[0042] In the above embodiment, the latch unit that is not linked to the handle is configured to be released by applying force to the door body (door body) like the roller latch 7, but this is not limiting. Instead of providing a mechanism for releasing the latch unit in the handle, for example, a latch release button may be provided separately from the handle, and the latch unit may be released when the latch release button is pressed, thereby making it a latch unit that is not linked to the handle.

[0043] In addition, in the above embodiment, the sleeve portion 4 is provided and the opposing portion is the sleeve portion 4, but this is not limited to this. The sleeve portion 4 may not be provided. For example, in a configuration in which the sleeve portion 4 is not provided, the opposing portion may be formed by the vertical frame of the frame body or the wall of the building. In this case, the latch portion may be provided on the vertical frame of the frame body or the wall of the building.

[0044] In the above embodiment, the sleeve portion 4 as the opposing portion is an openable / closable sub-door, but the present invention is not limited to this. The sleeve portion 4 as the opposing portion may be configured to be unable to be opened or closed.

[0045] In the above embodiment, the handle has a vertical member extending in the vertical direction, but 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 body), or in the shape of a handle that is recessed from the surface of the door body (door body).
