Description

This disclosure relates to door panels.

2. Description of the Related Art Door panels having openings through which pets (companies) can pass are known in the art. Such openings for pets to pass through are provided with a passage door for opening and closing the openings.
For example, the following Patent Document 1 discloses a door device for pets that has a curtain attached to the upper part of a frame-shaped base attached around the opening formed in the mesh of a screen door, and which can be attached and detached by a surface fastener to open and close the opening.

JP 2015-175176 A

However, in the passage door device described in Patent Document 1, although the door that opens and closes the opening can be attached and detached, because the door that opens and closes the opening is a fabric curtain, there is a concern that it may open due to wind or the difference in air pressure between the inside and outside of the room, or close in a bent state.

This disclosure was made in consideration of the above situation, and aims to provide a door panel that allows the passage door to be easily attached and detached, while still being able to stably close the pet passage opening.

To achieve the above object, the door panel according to the present disclosure comprises a panel body provided with a pet passage opening through which a pet can pass, and a passage door that is hung from the panel body side so as to be freely rotatable around its upper end as a fulcrum and opens and closes the pet passage opening, and is characterized in that at least the upper end portion of the passage door is made in the shape of a flexible plate, and by bending the upper end portion of the passage door, it is possible to detach the shaft portion provided on one of the two ends of the passage door in the door width direction and the panel body side from the bearing portion provided on the other side.

The door panel disclosed herein is configured as described above, allowing the passage door to be easily attached and detached while still allowing the pet passage opening to be stably closed.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
In some drawings, some of the detailed reference numerals used in other drawings are omitted.
In each of the following embodiments, directions such as up and down directions will be described based on the state in which the door panel and door device equipped with the door panel according to each embodiment are installed.

1 to 6 are diagrams that diagrammatically show an example of a door panel according to the first embodiment and a modified example thereof, and an example of a sliding door device as a door device equipped with the door panel.
As shown in Fig. 1, the door panel 1 according to this embodiment includes a panel body 10 provided with a pet passage opening 29 through which a pet can pass. With this configuration, even when the door panel 1 is closed, a pet can pass through the pet passage opening 29. The pet passage opening 29 is provided on the lower end side of the panel body 10 so that a pet can pass through.
In this embodiment, as shown in Fig. 4(a), the pet passage opening 29 is provided at the lower end corner of the door edge side of the panel body 10 so as to open to the door edge side and downward. With this configuration, the pet does not need to straddle, and the physical burden on the pet can be reduced, compared to a configuration in which a remaining portion is provided on the lower side of the opening through which the pet passes. In addition, when the door panel 1 is used as a sliding door panel, even if the door panel 1 is moved to the open side while the pet is passing through, contact between the pet and the door panel 1 can be reduced because the pet passage opening 29 opens to the door edge side.

3(a) to 3(c), the door panel 1 is hung from the panel body 10 side so as to be rotatable about its upper end as a fulcrum, and is provided with a passage door 30 that opens and closes the pet passage opening 29. With this configuration, even when the door panel 1 is closed, the pet can still pass through by pushing open the passage door 30, while the pet passage opening 29 can be closed by the passage door 30.
One of the side surfaces of the pet passage opening 29 facing the end surface of the door tail side of the passage door 30 and the end surface of the door tail side of the passage door 30 in the closed position is provided with an attraction part 34 that attracts the attracted part 23 provided on the other side by magnetic force. With this configuration, even if the configuration does not include the remaining part as described above, the attraction part 34 can attract the attracted part 23 to maintain the passage door 30 in the closed position. In other words, if the configuration includes the remaining part as described above, it is possible to provide an attraction part and an attracted part at the lower end of the remaining part and the passage door, but it is possible to provide the attraction part 34 and the attracted part 23 even if the configuration does not include the remaining part. This allows the passage door 30, which displaces in a pendulum shape after the pet opens the passage door 30 and passes through it, to be stopped quickly in the closed position. An example of a specific configuration of the pet passage opening 29 and the passage door 30 will be described later.

1, the door panel 1 is suspended and supported by an upper rail 41 so as to be slidable in the door width direction. In other words, the door panel 1 constitutes a sliding door panel that is constructed as an upper-suspended type.
At the lower end of the panel body 10, a guide groove 14 for receiving the guide parts 7a, 8a provided on the floor side is provided so as to extend in the door width direction on the door tail side of the pet passage opening 29. With this configuration, while allowing the passage of pets as described above, the guide parts 7a, 8a inserted into the guide groove 14 can suppress the swing of the lower end side of the door panel 1 suspended and held on the upper rail 41 in the door thickness direction.
The guide groove 14 is provided with an attraction portion 14a that attracts the guide portions 7a, 8a, which are embedded in the floor side and can be freely raised and lowered, by magnetic force. With this configuration, compared to a configuration in which a guide groove for a fixing pin is provided, the gap between the lower end of the through door 30 in the closed position and the floor side can be reduced while effectively increasing the effective opening width. In other words, when the remaining dimension of the door panel 1 (the dimension of the portion protruding toward the entrance 9 in the fully open position) is reduced to position the through door 30 above the fixing pin, it is necessary to increase the gap between the lower end of the through door 30 and the floor side so that the through door 30 does not interfere with the fixing pin. According to the above configuration, even when the remaining dimension of the door panel 1 is reduced to position the through door 30 above the guide portion 7a, if the guide groove 14 portion passes through, the guide portion 7a will sink into the floor side, so the gap between the lower end of the through door 30 and the floor side can be reduced. Furthermore, compared to a configuration in which a guide groove for a fixing pin is provided, there is no need to increase the groove depth to absorb unevenness on the floor side, and the groove depth of the guide groove 14 can be effectively reduced.

The sliding door device A according to this embodiment includes a door panel 1 and an upper rail 41 that guides the upper end side of the door panel 1. As shown in Figs. 2(a) and (c), the sliding door device A includes a first guide member 7 having a guide portion 7a that is inserted into the guide groove 14 of the door panel 1 in the closed position, and a second guide member 8 having a guide portion 8a that is inserted into the guide groove 14 of the door panel 1 in the open position. With this configuration, the first guide member 7 and the second guide member 8 can suppress the swing of the door panel 1 in the door thickness direction in the closed position and the open position while effectively increasing the effective opening width. In other words, since the pet passage opening 29 is provided at the lower end corner of the door tip side of the door panel 1, it is difficult to provide the guide groove 14 over the entire door width direction of the door panel 1 itself. For example, it is possible to configure the lower end side of the door panel 1 that moves between the closed position and the open position to be guided by one guide member, but in that case, it is necessary to increase the remaining dimension of the door panel 1. With the above configuration, the first guide member 7 and the second guide member 8 can suppress the swing of the door panel 1 in the door thickness direction in the closed and open positions, and can also eliminate any remaining part, effectively increasing the effective opening width.

In the installation structure of the sliding door device A, a wall body (first wall body) 3 is provided on at least one side of the door thickness direction of the door panel 1 in the open position. With this configuration, the door panel 1 can be installed in a sleeve wall or a door pocket. In this installation structure, the second guide member 8 is provided so as to be located on the door tail side rather than the center of the wall width direction of the first wall body 3. With this configuration, the lower end side of the door panel 1 in the final stage of moving from the closed position to the open position and the door panel 1 in the initial stage of moving from the open position to the closed position can be guided by the second guide member 8. In this installation structure, the first guide member 7 is provided so that the guide portion 7a is located at the door tip side end of the guide groove 14 of the door panel 1 with the guide portion 8a of the second guide member 8 located at the door tail side end of the guide groove 14 of the door panel 1, as shown in FIG. 2(b). With this configuration, when the door panel 1 moves between the open position and the closed position, the guide portions 7a, 8a of both the first guide member 7 and the second guide member 8 are inserted into the guide grooves 14, allowing the door panel 1 to be opened and closed smoothly. In addition, since the second guide member 8 is positioned closer to the end of the door than the center of the first wall 3 in the wall width direction, the first guide member 7 is positioned on the first wall 3 side in the opening width direction of the entrance 9, making it less likely that the first guide member 7 will get in the way.

In this installation structure, walls (first wall 3 and second wall 4) that divide the door pocket 2 are provided on both sides of the door panel 1 in the open position in the door thickness direction. With this configuration, the door panel 1 can be installed inside the door pocket. In this installation structure, the second wall 4, which is one of these walls 3 and 4, is provided with a door pocket inspection opening 5 that allows inspection of the second guide member 8, and a lid 6 that opens and closes the door pocket inspection opening 5. With this configuration, the second guide member 8 installed inside the door pocket 2 can be inspected by opening the lid 6, even while the door panel 1 is stored in the door pocket.

Specifically, as shown in Figs. 1 and 2, the installation structure is such that a single door panel 1 is installed in a door pocket in a one-sided sliding manner.
The door panel 1 is attached to a door frame including an upper frame 40 provided with an upper rail 41. The door frame may be provided in the sliding door device A. The door frame includes an upper frame 40, a door-end side vertical frame 42 whose upper end is joined to the door-end side end of the upper frame 40, a door-end side vertical frame 44 whose upper end is joined to the door-end side end of the upper frame 40, and a pair of intermediate vertical frames (middle mullions) 45, 45 that define the door pocket opening. The entrance 9 opened and closed by the door panel 1 is defined by the upper frame 40 (upper rail 41) on the upper side, the door-end side on the door-end side vertical frame 42, and the door-end side on the pair of intermediate vertical frames 45, 45. The lower side of the entrance 9 may be defined by a floor or by an appropriate lower frame.

The upper frame 40 may be fixed to an appropriate upper frame base that constitutes the ceiling of an opening in a building such as a residence. In the illustrated example, a hanging wall that constitutes a partition wall is provided above the upper frame 40, but instead of this embodiment, the upper frame 40 may be attached to or embedded in the ceiling.
The upper rail 41 is fixed to the underside of the upper frame 40. At least the upper portion of the upper rail 41 may be fitted and fixed in a receiving groove formed on the underside of the upper frame 40. The upper rail 41 is provided with guide grooves extending in the longitudinal direction for guiding the runners 12, 12 constituting the guided member provided on the upper end side of the door panel 1.

The leading edge vertical frame 42 and trailing edge vertical frame 44 may be fixed to an appropriate vertical frame base that constitutes the opposing inner surfaces of the opening.
The door end vertical frame 42 is provided with a receiving groove (door clearance groove) 43 that receives the door end end of the door panel 1 and extends in the vertical direction (direction along the door height direction). This receiving groove 43 is provided to open toward the center of the opening width direction of the entrance 9. The groove width dimension of this receiving groove 43 along the door thickness direction may be an appropriate dimension according to the door thickness dimension of the door end so that the door end end of the door panel 1 can be received. In the illustrated example, the receiving groove 43 is tapered such that the groove side walls on both sides in the groove width direction expand toward the opening side (see also FIG. 5(a)).
The end of the door panel 1 in the fully open state abuts against or is close to the end-of-door-side vertical frame 44. A buffer body against which the end of the door panel 1 abuts or is elastically abutted against may be provided on a projected surface of the end-of-door-side vertical frame 44 facing the center of the opening width direction of the entrance 9.

The pair of intermediate vertical frames 45, 45 may have their upper ends fixed to a longitudinal midpoint of the upper frame 40 and their lower ends fixed to the floor.
The door pocket 2 is provided so as to open toward the entrance 9, which is one side in the door width direction, and constitutes a storage space for the door panel 1. The dimension of the door pocket 2 along the door width direction (storage direction) is set according to the door width dimension of the door panel 1 so that the door panel 1 can be stored. In this embodiment, the dimension of the door pocket 2 along the door width direction is set to a dimension that can store the entire door panel 1. In other words, the door panel 1 is installed so that no remaining part is left protruding toward the entrance 9 in the open position (fully open position). In the illustrated example, an example is shown in which the door end side end surface of the door panel 1 in the fully open position and the projected surface of the intermediate vertical frames 45, 45 facing the center of the opening width direction of the entrance 9 are approximately on the same plane.

The upper side of this door pocket 2 is defined by an upper frame 40 (upper rail 41), both sides in the door thickness direction are defined by a first wall body 3 and a second wall body 4, and the rear side in the storage direction is defined by a door trailing side vertical frame 44. The lower side of this door pocket 2 may be defined by a floor.
The intermediate vertical frames 45, 45 are provided along the ends of the first wall body 3 and the second wall body 4 on the entrance/exit 9 side.
The first wall body 3 and the second wall body 4 may be formed by providing a series of wall base boards that constitute the partition wall, or may have a pair of sleeve-wall-like wall parts provided separately from the partition wall, or may be formed integrally to form the door pocket 2. In the illustrated example, the first wall body 3 and the second wall body 4 on both sides in the door thickness direction are each formed by two wall base boards provided with an appropriate spacer between them.

As shown in Fig. 2(a), the door pocket inspection hatch 5 is provided so as to penetrate the second wall 4 in the wall thickness direction. As shown in Fig. 1, the door pocket inspection hatch 5 is provided at the lower end side portion of the second wall 4. The height position at which the door pocket inspection hatch 5 is provided, the dimension along the door width direction, and the dimension along the up-down direction may be set to an appropriate position and dimension depending on the maintainability of the second guide member 8, the presence or absence of a baseboard, etc.
The inner circumferential surface of the opening of this door pocket inspection hatch 5 may be configured by a frame-like member that holds the lid body 6 so that it can be opened and closed freely.
The lid 6 may be detachable from the door pocket inspection hatch 5, or one end of the lid 6 may be rotatably connected to the door pocket inspection hatch 5. The frame-shaped member and the lid 6 that constitute the door pocket inspection hatch 5 may be provided in the sliding door device A.

In this example, the first guide member 7 is provided so as to be located outside the door pocket 2. The illustrated example shows an example in which it is provided so as to be located in a portion near the door pocket opening. In this example, the first guide member 7 is provided in a recessed manner on the floor side, and the guide portion 7a is provided so as to be able to freely appear and disappear. With this configuration, even if the first guide member 7 is provided so as to be located outside the door pocket 2, it is unlikely to get in the way.
The second guide member 8 is provided so as to be located on the inner side (the side of the trailing edge vertical frame 44) of the center in the door width direction of the door pocket 2. In this example, the second guide member 8 is provided in a recessed state on the floor side, similar to the first guide member 7, and is configured so that the guide portion 8a is provided so as to be freely protruding and retracting.
The first guide member 7 and the second guide member 8 may be configured to hold the guide parts 7a, 8a so that they can be raised and lowered in the vertical direction relative to a casing embedded in the floor side. Each guide part 7a, 8a may have a two-stage telescopic structure. Also, each guide part 7a, 8a may be configured to have an attracted part that is attracted by magnetic force to an attracting part 14a (see FIG. 3(c)) provided on the guide groove 14 side. In other words, the first guide member 7 and the second guide member 8 may be so-called magnet guides. In this case, a magnet or a ferromagnetic material that constitutes the attracted part may be embedded in the upper end of the guide parts 7a, 8a.

As shown in FIG. 1, the door panel 1 is a generally rectangular flat plate that is elongated in the vertical direction. The height (length) of the door panel 1 may be set according to the opening height of the doorway 9 that is opened and closed by the door panel 1. The height of the door panel 1 may be, for example, about 1800 mm to 2100 mm. If the opening height of the doorway 9 is approximately the same height as the ceiling height from the floor to the ceiling, the height of the door panel 1 may be, for example, about 2400 mm to 3000 mm. The width of the door panel 1 may be set according to the opening width of the doorway 9, for example, about 600 mm to 1200 mm. The thickness of the door panel 1 may be, for example, about 20 mm to 40 mm.

A handle 11 is provided on both sides of the door thickness direction of the door front end of this door panel 1.
Runners 12, 12 suspended from the upper rail 41 are provided on both sides of the upper end of the door panel 1 in the door width direction. These runners 12, 12 may be configured to include rolling elements such as rollers that roll on guide pieces provided on the upper rail 41.
The illustrated example shows an example in which a relatively small light-transmitting portion 13 is provided at the upper end of the door front end of the door panel 1. The illustrated example shows an example in which the light-transmitting portion 13 is substantially circular when viewed in the door thickness direction, but it may be rectangular or have other shapes, and may be provided in other locations.
The panel body 10 constituting this door panel 1 may be, for example, a so-called flush panel in which a surface material is attached to a panel core material having a frame around all four sides. In the example shown, an example is shown in which a mirror-shaped part having a thickness smaller than that of the surrounding area is provided in the center part of the panel body 10, but both sides in the door thickness direction may be flat over almost the entire surface, or various other configurations may be used.

The guide groove 14 provided at the lower end of the panel body 10 is provided to open downward and extend in the door width direction. The door leading side of the guide groove 14 is provided to open at the opening inner side surface 15b facing the door leading side of the opening 15 constituting the pet passage opening 29 of the panel body 10, and the door trailing side is provided to open at the door trailing side end surface of the panel body 10. In other words, the guide groove 14 is provided over the entire door width direction of the lower end of the panel body 10 on the door trailing side of the pet passage opening 29. Instead of such a mode, the guide groove 14 may be provided over almost the entire door width direction of the lower end of the panel body 10 on the door trailing side of the pet passage opening 29. The groove depth of the guide groove 14 may be about 5 mm to 10 mm when the guide parts 7a and 8a are magnet guides as described above. The groove width of the guide groove 14 at both ends in the door width direction is made larger than the groove width at the central part in the door width direction so as to easily receive the guide parts 7a and 8a. As shown in Fig. 2(a), the first guide member 7 is provided so as to be adjacent to the center of the door width direction of the part where the groove width of the end of the guide groove 14 is made large when the door panel 1 is in the closed position. With this configuration, it is possible to easily receive the guide part 8a while suppressing rattling in the door thickness direction of the end of the lower end of the door panel 1 in the closed position.
The guide groove 14 may be defined by a groove member fitted into a fitting groove provided at the lower end of the panel main body 10. Such a groove member may have magnets embedded as suction parts 14a (see FIG. 3(c)) that attract the attracted parts of the guide parts 7a and 8a at both ends in the door width direction, and a ferromagnetic material such as a steel plate embedded as suction part 14a that attracts the attracted parts of the guide parts 7a and 8a at the center part in the door width direction.

As shown in Figures 3(a) and 4(a), an upper cover part 21 that defines the upper side of the pet passage opening 29 and a trailing edge side cover part 22 that defines the trailing edge side of the pet passage opening 29 are attached to the panel body 10. With this configuration, the upper cover part 21 and the trailing edge side cover part 22 can cover the opening inner top surface 15a and the opening inner side surface 15b of the opening 15 that constitutes the pet passage opening 29 provided in the lower end corner part on the leading edge side of the panel body 10 (see also Figure 5(c)).
3(a) and 3(c), a recess 22c is provided at the lower end of the trailing edge side cover part 22, which opens downward so as to connect the guide groove 14 to the pet passage opening 29. With this configuration, while covering the opening inner top surface 15a and the opening inner side surface 15b of the opening 15 as described above, it is possible to suppress interference between the guide parts 7a, 8a provided on the floor side and the trailing edge side cover part 22. In addition, it is possible to suppress the guide parts 7a, 8a, which are freely retractable as described above, from getting caught on the trailing edge side cover part 22 even when they are in the middle of being retracted.

As shown in Fig. 5(c), the suction portion 34 or the attracted portion 23 that maintains the passage door 30 in the closed position is provided on the back side of the trailing edge cover portion 22. With this configuration, the suction portion 34 or the attracted portion 23 provided on the side of the pet passage opening 29 can be made less noticeable by the trailing edge cover portion 22.
As shown in Figures 3(a) to 3(c), the suction portion 34 or the attracted portion 23 provided on the trailing end surface of the passage door 30 is provided at the vertical center of the passage door 30. With this configuration, the center of gravity is higher and the swing range is smaller than in a configuration in which the suction portion 34 or the attracted portion 23 is provided at the lower end of the trailing end surface of the passage door 30, so that the passage door 30, which displaces like a pendulum, can be stopped at the closed position more quickly. In addition, it is also possible to prevent the suction portion 34 or the attracted portion 23 from interfering with the guide portions 7a, 8a of the first guide member 7 and the second guide member 8, which are magnetic guides.

As shown in FIG. 5(a), an axis 37 is provided on one of the upper end of the trailing edge end face of the through door 30 and the upper end of the side face of the pet passage opening 29, and a bearing portion (tailing edge bearing portion) 24 that receives the axis 37 is provided on the other. The axis 37 or trailing edge bearing portion 24 is provided with a spacer portion 36a that ensures a gap between the trailing edge end face of the through door 30 and the side face of the pet passage opening 29. With this configuration, even though the suction portion 34 and the attracted portion 23 are provided on the trailing edge end face of the through door 30 and the side face of the pet passage opening 29 as described above, it is possible to prevent the trailing edge end of the through door 30 from excessively contacting the side of the pet passage opening 29.

As shown in FIG. 5B, at least the upper end portion of the through door 30 is made into a plate shape having flexibility. The upper end portion of the through door 30 can be bent to detach the shaft portions 37, 37 provided on the other side from the bearing portions 24, 26 provided on either end of the through door 30 in the door width direction or on the panel body 10 side. With this configuration, the through door 30 is opened and closed by rotating the upper end side of the plate-shaped through door 30 around the shaft portions 37, 37. As a result, compared to a configuration in which the through door 30 is a cloth curtain or the like, it is less likely to be opened by wind or the difference in air pressure between the inside and outside of the room, and is less likely to be closed in a bent state, so that the pet passage opening 29 can be stably closed by its own weight. In addition, the through door 30 can be easily removed from the panel body 10 side by bending the upper end portion of the through door 30 in the door thickness direction, and the through door 30 can be easily attached to the panel body 10 side by bending it in the same way. This allows the door 30 to be removed until the pet gets used to having it open, and allows maintenance to be easily performed by removing the door 30.

The shafts 37, 37 are provided at both ends of the passage door 30 in the door width direction, and the bearings 24, 26 are provided on the panel body 10 side. For example, if the shaft 37 is provided on the panel body 10 side, the shaft 37 will protrude into the pet passage opening 29 when the passage door 30 is removed, which may cause a concern of interference with a pet, but with the above configuration, such a concern does not exist.
Specifically, the bearings 24, 26 are provided in the through door holding frame 20 including the upper cover part 21 and the trailing edge side cover part 22. The trailing edge side bearing part 24 of the bearings 24, 26 is provided in the trailing edge side cover part 22, and the leading edge side bearing part 26 is provided in the leading edge cover part 25 that covers the leading edge side end face of the upper cover part 21. The trailing edge side bearing part 24 and the leading edge side bearing part 26 face each other and open along the door width direction. The trailing edge side bearing part 24 and the leading edge side bearing part 26 are provided so as to be in the same position (overlapping) as seen in the door width direction. In the illustrated example, the trailing edge side bearing part 24 and the leading edge side bearing part 26 are provided in the center of the panel body 10 in the door thickness direction, but may be provided in a position offset to one side in the door thickness direction.

The opening 15 of the panel body 10 to which the passing door holding frame 20 is attached is defined by an opening inner top surface 15a facing downward and an opening inner side surface 15b facing the door end side, as shown in Fig. 5 (c), and is formed by cutting out the lower end corner of the door end side of the panel body 10. In the illustrated example, the inside corner where the opening inner top surface 15a and the opening inner side surface 15b intersect is formed into a concave curved surface. This opening 15 may be formed by cutting or the like. When the panel body 10 is a flush panel, an appropriate batten member may be provided at a position corresponding to the opening inner top surface 15a and the opening inner side surface 15b.
The passage door holding frame 20 is substantially L-shaped when viewed in the door thickness direction so as to fit along the opening inner top surface 15a and opening inner side surface 15b of the opening 15.

As shown in Figures 4 (a) and 5 (a), the upper cover portion 21 and the end-of-door cover portion 22 are arranged to cover not only the inner top surface 15a and inner side surface 15b of the opening 15, but also both sides in the door thickness direction near the inner top surface 15a and inner side surface 15b of the panel main body 10.
In this example, the upper cover part 21 and the trailing edge side cover part 22 include a first cover part 21a, 22a that covers one side of the panel body 10 in the door thickness direction, and a second cover part 21b, 22b that covers the other side of the panel body 10 in the door thickness direction (see also FIG. 5(c)). In the illustrated example, the first cover part 21a of the upper cover part 21 and the first cover part 22a of the trailing edge side cover part 22 are continuous, and the second cover part 21b of the upper cover part 21 and the second cover part 22b of the trailing edge side cover part 22 are continuous, but these may be separate.

As shown in Figure 5 (c), the first cover portion 21a of the upper cover portion 21 comprises an upper plate-shaped portion arranged to cover the inner top surface 15a of the opening, and a front plate-shaped portion arranged to extend upward from one side edge portion in the door thickness direction of the upper plate-shaped portion and cover one side of the panel main body 10 in the door thickness direction.
The second cover portion 21b of the upper cover portion 21 comprises an upper plate-shaped portion arranged to cover the upper plate-shaped portion of the first cover portion 21a, and a front plate-shaped portion arranged to extend upward from the other side edge portion in the door thickness direction of the upper plate-shaped portion and cover the other side of the panel main body 10 in the door thickness direction.
In other words, the upper plate-shaped portion of the first cover part 21a and the upper plate-shaped portion of the second cover part 21b are stacked vertically to cover the inner top surface 15a of the opening. Also, the front plate-shaped portion of the first cover part 21a and the front plate-shaped portion of the second cover part 21b sandwich the panel body 10 from both sides in the door thickness direction, covering both sides in the door thickness direction near the inner top surface 15a of the opening.

The first cover portion 22a of the trailing edge side cover portion 22 comprises a trailing edge side plate portion arranged to cover the inner surface 15b of the opening, and a front side plate portion arranged to extend from one side edge portion in the door thickness direction of the trailing edge side toward the trailing edge and to cover one side of the panel main body 10 in the door thickness direction.
The second cover portion 22b of the trailing edge side cover portion 22 comprises a trailing edge side plate portion arranged to cover the trailing edge side plate portion of the first cover portion 22a, and a front side plate portion arranged to extend from the other side edge portion in the door thickness direction of the trailing edge side plate portion toward the trailing edge and cover the other side of the panel main body 10 in the door thickness direction.
In other words, the trailing edge side plate portion of the first cover portion 22a and the trailing edge side plate portion of the second cover portion 22b are overlapped in the door width direction to cover the opening inner side surface 15b. Also, the front side plate portion of the first cover portion 22a and the front side plate portion of the second cover portion 22b sandwich the panel body 10 from both sides in the door thickness direction to cover both sides in the door thickness direction near the opening inner side surface 15b.
The recess 22c is provided at the lower end of the trailing edge side plate portion of the first cover portion 22a and the second cover portion 22b of the trailing edge side cover portion 22 so as to open downward and penetrate in the door width direction. The dimensions of the recess 22c in the door thickness direction and in the vertical direction may correspond to the groove width and groove depth of the guide groove 14.

The upper cover portion 21 and the trailing edge side cover portion 22 may be made applicable to panel bodies having different door thickness dimensions by adjusting the overlapping dimensions between the upper plate portion and trailing edge side plate portion of the first cover portion 21a, 22a and the upper plate portion and trailing edge side plate portion of the second cover portion 21b, 22b.
The upper cover part 21 and the trailing edge side cover part 22 may be attached to the panel body 10 by an appropriate adhesive, adhesive material, or a fastener such as a screw. In the illustrated example, the spacer parts 25c and 27 are provided between the upper plate part of the first cover part 21a of the upper cover part 21 and the opening inner top surface 15a. The spacer parts 25c and 27 are provided so that the upper cover part 21 does not interfere with the recessed corner between the opening inner top surface 15a and the opening inner side surface 15b, which are concavely curved as described above, in other words, so that the trailing edge side cover part 22 can abut against the opening inner side surface 15b. In the illustrated example, the spacer part 25c on the leading edge side is provided on the leading edge cover part 25, and the spacer part 27 on the trailing edge side is provided on the upper plate part of the first cover part 21a.

The trailing edge cover part 22 is provided with an attracted part 23 as one of the attracting part 34 and the attracted part 23. The attracted part 23 may be a ferromagnetic material such as a steel plate attracted to the magnet as the attracting part 34, or may be a magnet. In the illustrated example, the attracted part 23 is a thin plate whose thickness direction is the door width direction. The attracted part 23 is provided along the back surface facing the opening inner side surface 15b of the second cover part 22b of the trailing edge cover part 22. The attracted part 23 may be fixed to the back surface of the second cover part 22b with an adhesive or a sticky material. The first cover part 22a of the trailing edge cover part 22 is provided with a notched recess for receiving the attracted part 23. Instead of providing the attracted part 23 on the back surface side of the second cover part 22b, the attracted part 23 may be provided so as to be exposed on the front surface side facing the leading edge side of the trailing edge cover part 22.
The trailing edge side bearing portion 24 is provided so as to open toward the leading edge side at the upper end portion of the trailing edge side cover portion 22. In the illustrated example, the trailing edge side bearing portion 24 is provided so as to penetrate the second cover portion 22b and the first cover portion 22a of the trailing edge side cover portion 22 in the door width direction, which is the thickness direction of these cover portions. When the overlapping dimension of the trailing edge side plate portions of the first cover portion 22a and the second cover portion 22b is adjustable as described above, the trailing edge side bearing portion 24 of the first cover portion 22a may be elongated in the door thickness direction.

The door end cover portion 25 is arranged so that the door end side facing the door end is approximately flush with the door end side end face of the panel main body 10.
As shown in Fig. 3(b) and Fig. 5(c), the door end cover part 25 has a portion covering the door end side end surface of the upper plate part of the first cover part 21a and the second cover part 21b of the upper cover part 21, and a portion covering the door end side end surface of the front plate part on both sides in the door thickness direction. The portion covering the door end side end surface of the front plate part includes rising pieces 25b, 25b that rise up so as to respectively follow both side edges in the door thickness direction of the door end side end surface of the panel main body 10. These rising pieces 25b, 25b may be provided with a portion that follows the chamfered portion of both side edges in the door thickness direction of the door end side end surface of the panel main body 10.
As shown in Fig. 5(a), the dimension of this door end cover part 25 along the door thickness direction is the thickness dimension of the panel body 10 plus the thickness dimension of the front plate-shaped parts on both sides of the door thickness direction of the upper cover part 21. The groove width of the groove bottom of the receiving groove 43 of the door end side vertical frame 42 is set according to the thickness dimension of the panel body 10 in order to suppress the swing of the door panel 1 in the door thickness direction on the door end side. Therefore, the door end cover part 25 is formed so that the dimension along the door thickness direction on the door end side is set according to the groove width of the groove bottom of the receiving groove 43, and the dimension along the door thickness direction becomes larger toward the door end side.

The door-end cover part 25 has a protruding piece 25a that protrudes downward from the part that covers the door-end side end face of the upper cover part 21 and is provided with a door-end side bearing part 26. The door-end side bearing part 26 is provided so as to open toward the door tail side. This door-end side bearing part 26 is a bottomed hole so as not to open on the door-end side surface facing the door-end side of the protruding piece 25a.
At least both corners in the door thickness direction of the lower end of the protruding piece 25a are chamfered as shown in Fig. 3(b). With this configuration, it is possible to prevent a pet from getting caught on the corners of the protruding piece 25a or from being injured by the corners. Both corners in the door thickness direction of the lower end of the protruding piece 25a may be chamfered in a C-shape or an R-shape, or the entire lower end may be formed into a multifaceted shape or a convex curved surface.

The dimension of the protruding piece 25a in the vertical direction may be an appropriate dimension so that the shaft 37 described below can be held in the door-end bearing portion 26, and from the viewpoint of strength, etc. The dimension of the protruding piece 25a in the vertical direction from the lower surface of the upper cover portion 21 may be about 10 mm to 20 mm.
The dimension of this protruding portion 25a along the door width direction may be approximately the same as the groove depth dimension of the receiving groove 43 in the door front vertical frame 42.
The spacer portion 25c of the door end cover portion 25 may be attached to the panel body 10 by a suitable adhesive, adhesive material, or fastener such as a screw. Instead of being provided separately from the upper cover portion 21, the door end cover portion 25 may be provided integrally with the upper cover portion 21.
The door end cover portion 25, the upper cover portion 21 and the lower cover portion 22 may be made of a hard synthetic resin such as ABS, or may be made of metal.
The passage door holding frame 20 that holds the passage door 30 is not limited to the above-described configuration, and may have various other configurations.

As shown in FIG. 4(a), when the door panel 1 is in the closed position, the pet passage opening 29 is defined by the upper cover portion 21 and the floor on both sides in the vertical direction, and by the door end side vertical frame 42 and the door end side cover portion 22 on both sides in the door width direction. The height dimension of this pet passage opening 29 along the vertical direction and the width dimension along the door width direction may be appropriately set so that a pet can pass through. The height dimension of this pet passage opening 29 may be a dimension corresponding to small dogs and cats that tend to be kept indoors, and may be, for example, about 250 mm to 400 mm. The width dimension of the pet passage opening 29 may be a dimension corresponding to small dogs and cats, as described above, and may be, for example, about 150 mm to 300 mm. The height dimension and width dimension of the pet passage opening 29 are not limited to dimensions corresponding to small dogs and cats, and may be dimensions corresponding to medium-sized dogs, etc.

As shown in Figure 3 (a), the passing door 30 that opens and closes this pet passage opening 29 has a height dimension in the vertical direction and a width dimension in the door width direction that correspond to the height dimension and width dimension of the pet passage opening 29.
The height dimension of this passing door 30 may be smaller than the height dimension of the pet passage opening 29. With this configuration, the guide portion 7a is free to appear and disappear as described above, so the lower end of the passing door 30 tends not to interfere, but interference can be suppressed even when the guide portion 7a is not smoothly inserted or the opening speed of the door panel 1 is fast. The height dimension of this passing door 30 may be such that its lower end is located slightly (for example, about 2 mm to 10 mm) above the lower end surface of the panel main body 10. In the illustrated example, the passing door 30 has a height dimension such that its lower end is approximately the same height as the groove bottom of the guide groove 14 (more specifically, slightly below the groove bottom). Instead of this embodiment, the height dimension of the passing door 30 may be such that its lower end is the same height as the lower end surface of the panel main body 10.
The width dimension of this passage door 30 may be slightly smaller than the width dimension of the pet passage opening 29 so that both ends of the passage door 30 in the door width direction do not interfere with the front door vertical frame 42 and the rear door cover portion 22.

In this passage door 30, the lower portion 35 is harder than the upper portion 31 including the upper end portion. With this configuration, while the upper portion 31 including the upper end portion is flexible, the lower portion 35 which tends to come into contact with pets is hard, so that damage to the lower portion 35 can be suppressed and the configuration can be made easy to wipe and clean.
As shown in Fig. 3(c) and Fig. 5(b), the upper portion 31 has flexibility to bend appropriately when the pet opens the passage door 30 to pass through it or when the passage door 30 is attached to or detached from the passage door holding frame 20. The upper portion 31 may have appropriate flexibility so that the user can bend the passage door 30 by hand when attaching or detaching the passage door 30. The upper portion 31 may be made of soft acrylic resin such as acrylic soft polymer or soft synthetic resin such as polyvinyl chloride resin. The upper portion 31 may have a Shore A hardness of about 70° to 90°, preferably about 70° to 85°, measured using a type A durometer in accordance with JIS K7215.
The lower portion 35 may be made of a hard synthetic resin such as ABS as long as it is harder than the upper portion 31. In the illustrated example, a hook-shaped piece is provided at the lower end of the lower portion 35 so as to bulge on both sides in the door thickness direction and to define a groove that opens downward, but the shape is not limited to this. The upper portion 31 and the lower portion 35 may be made of an opaque resin, or a transparent or translucent resin.

The thickness of the upper portion 31 and the lower portion 35 may be, for example, about 1.5 mm to 3.0 mm.
In this example, the upper portion 31 and the lower portion 35 are joined at a joint 33 located approximately in the center of the passage door 30 in the up-down direction. The upper portion 31 and the lower portion 35 may be joined by fitting a mating convex portion provided on one of the lower end of the upper portion 31 and the upper end of the lower portion 35 constituting the joint 33 into a mating concave portion provided on the other portion, using an appropriate adhesive or the like. Instead of making the lower portion 35 harder than the upper portion 31 in this manner, the lower portion 35 may have the same hardness as the upper portion 31, or the lower portion 35 and the upper portion 31 may be formed in a continuous manner from the same material.

As shown in FIG. 4(b), the suction portion 34 that is attracted to the attracted portion 23 of the tail-side cover portion 22 is provided in the present embodiment at approximately the center in the vertical direction. As shown in FIG. 3(b), the attracted portion 23 is provided so that it overlaps with the suction portion 34 when the passage door 30 is in the closed position, as viewed in the door width direction. The suction portion 34 is provided on the tail-side end surface of the joint portion 33. The suction portion 34 may be fitted into a recess provided in the joint portion 33 so as to open toward the tail-side, or may be provided in an embedded state. The suction portion 34 may be a magnet such as a neodymium magnet, and when the attracted portion 23 is a magnet, it may be a ferromagnetic material such as a steel plate. Instead of providing the suction portion 34 at approximately the center in the vertical direction of the passage door 30, the suction portion 34 may be provided in the lower portion of the upper portion 31 or the upper portion of the lower portion 35, which is the central portion in the vertical direction of the passage door 30. Alternatively, the suction portion 34 may be provided in the lower portion of the lower portion 35, which is the lower end portion of the passage door 30. In these cases, the suctioned portion 23 of the trailing edge cover portion 22 may be provided in an appropriate position so that it is located in accordance with the suction portion 34.

The shafts 37, 37 are provided on two hard shaft members 36, 36 that are inserted and held in shaft holding holes 32 that open at both ends of the passage door 30 in the door width direction. With this configuration, while at least the upper end portion of the passage door 30 is configured to have flexibility, the passage door 30 can be opened and closed stably by the two hard shaft members 36, 36 compared to a configuration in which the shafts 37, 37 are integrally formed with the passage door 30. This also makes it possible to extend the life of the passage door 30. In addition, since these shaft members 36, 36 are provided on both sides in the door width direction, the attachment and detachment of the passage door 30 is not hindered.
The shaft holding hole 32 of the passing door 30 is provided at the upper end of the upper portion 31 of the passing door 30. As shown in Fig. 5(a) , this shaft holding hole 32 is provided so as to penetrate the upper end of the upper portion 31 over the entire width of the door.

The shaft members 36, 36 are elongated in the door width direction. The length of the shaft members 36, 36 may be 60 mm or more. With this configuration, even if the passage door 30 is unintentionally removed and the shaft members 36, 36 fall out of the shaft holding hole 32 of the passage door 30, it is possible to prevent pets, infants, etc. from swallowing the shaft members 36, 36. The length of the shaft members 36, 36 may be formed so that a part of them protrudes from the swallowing judgment gauge when they are arranged obliquely inside the cylindrical part of the swallowing judgment gauge specified in JIS C8513. The length of the shaft members 36, 36 may be an appropriate length so as not to hinder the bending of the upper part 31 when the passage door 30 is attached and detached, and may be, for example, 80 mm or less, preferably 70 mm or less, or 65 mm ± 2 mm. In the example shown in the figure, the length of the shaft members 36, 36 is approximately 1/3 of the width dimension of the passage door 30.

The spacer portion 36a is provided on the shaft member 36. In this example, the spacer portions 36a, 36a are provided on both shaft members 36, 36. The spacer portion 36a of the shaft member 36 on the door end side may be configured to secure a gap between the surface facing the door end side of the protruding piece portion 25a of the door end cover portion 25 and the projected surface facing the door end side of the door end side vertical frame 42 and the door end side end face of the through door 30.
These shaft members 36, 36 have the same configuration. The spacer portions 36a, 36a of these shaft members 36, 36 are provided at the boundary between the shaft portions 37, 37 inserted into the trailing-end bearing portion 24 and the leading-end bearing portion 26 and the held shaft portions 38, 38 inserted into the shaft holding holes 32 so as to separate them. With this configuration, even if the shaft holding holes 32 are configured to be provided over the entire width of the passage door 30, it is possible to prevent the shaft portions 37, 37 from entering the shaft holding holes 32.

The outer diameter of the spacer portions 36a, 36a is larger than the inner diameter of the trailing-side bearing portion 24, the leading-side bearing portion 26, and the shaft holding hole 32. The thickness dimension of the spacer portions 36a, 36a along the axial direction may be about 0.5 mm to 1.5 mm. The spacer portions 36a, 36a may be integrally provided with the shaft members 36, 36, or may be separate and fitted into the annular grooves of the shaft members 36, 36. Instead of or in addition to the spacer portions 36a, 36a, an appropriate resin washer or the like having good sliding properties may be provided. Also, instead of or in addition to the configuration in which the spacer portions 36a, 36a are provided on the shaft members 36, 36, a configuration in which a flange-shaped spacer portion is provided on the trailing-side bearing portion 24 and the leading-side bearing portion 26 may be used. Furthermore, a configuration in which such spacer portions 36a, 36a are not provided may be used.

The outer diameter of the shaft portions 37, 37 corresponds to the inner diameter of the trailing edge side bearing portion 24 and the leading edge side bearing portion 26. The outer diameter of the shaft portions 37, 37 may be approximately the same as the inner diameter of the trailing edge side bearing portion 24 and the leading edge side bearing portion 26, or may be slightly smaller. The dimension of the shaft portions 37, 37 along the axial direction corresponds to the depth of the trailing edge side bearing portion 24 and the leading edge side bearing portion 26. The dimension of the shaft portions 37, 37 along the axial direction may be approximately the same as the depth of the trailing edge side bearing portion 24 and the leading edge side bearing portion 26, or may be slightly smaller or larger.
The dimension of the held shaft portions 38, 38 in the axial direction is made larger than the dimension of the shaft portions 37, 37 in the axial direction, and is made to account for the majority of the length of the shaft members 36, 36. With this configuration, the shaft members 36, 36 are less likely to fall off the shaft holding hole 32.
The outer diameter of the held shaft portions 38, 38 corresponds to the inner diameter of the shaft holding hole 32. The outer diameter of the held shaft portions 38, 38 may be substantially the same as or slightly larger than the inner diameter of the shaft holding hole 32. With this configuration, the shaft members 36, 36 are less likely to fall off the shaft holding hole 32.
These shaft members 36, 36 may be made of an appropriate metallic material such as stainless steel.

When attaching the pass-through door 30 configured as described above to the pass-through door holding frame 20 on the panel main body 10 side, as shown in Figure 5 (b), the upper portion 31 of the pass-through door 30 can be bent and each shaft portion 37, 37 can be fitted into the trailing edge side bearing portion 24 and the leading edge side bearing portion 26, respectively, to attach the door.
When removing the through door 30 from the through door holding frame 20, the upper portion 31 of the through door 30 may be bent to detach each shaft portion 37, 37 from the trailing edge bearing portion 24 and the leading edge bearing portion 26, thereby removing the door.

Next, a modified door panel and a modified door device including the same will be described with reference to FIG.
In the following modified examples and other embodiments described later, differences from the previously described example will be mainly described, and the same components will be given the same reference numerals and their description will be omitted or briefly described. In the following modified examples and other embodiments described later, description of the same effects as those in the previously described example will also be omitted or briefly described.

As shown in FIG. 6(a), the door panel 1A according to this modified example differs from the above-described example mainly in the configuration of the passage door holding frame 20A.
In this modified example, the through door holding frame 20A is provided with an extension 22d extending from the lower end of the tail end cover 22 toward the door tip. In addition, the extension 22d is provided with a groove 22e that communicates with the recess 22c of the tail end cover 22 and the guide groove 14. With this configuration, as shown in Figs. 6(b) and 6(c), in a configuration in which only one guide member 7A is provided, it is possible to reduce the remaining dimension at the fully open position, while suppressing the swing of the lower end of the door panel 1A in the door thickness direction. In other words, since the guide portion 7Aa of the guide member 7A can be received in the groove 22e of the extension 22d at the fully open position, the remaining dimension can be reduced. In addition, the guide member 7A can be a fixed pin instead of a magnet guide.

The extension dimension of the extension portion 22d along the door width direction may be an appropriate dimension from the viewpoint of reducing the remaining dimension and from the viewpoint of opening most of the lower side of the pet passage opening 29. The extension dimension of the extension portion 22d may be, for example, less than 1/2, and preferably 1/3 or less, of the width dimension of the pet passage opening 29. In the illustrated example, an example is shown in which the extension dimension of the extension portion 22d is about 3/10 of the width dimension of the pet passage opening 29.
The extension 22d may be provided integrally with the trailing edge side cover part 22, or may be a separate body from the trailing edge side cover part 22 and fixed to the trailing edge side cover part 22. Instead of being provided on the passage door holding frame 20A, the extension 22d may be formed by extending a groove member forming the guide groove 14 toward the pet passage opening 29. In this case, the groove member constituting the extension 22d may be subjected to an appropriate surface decorative treatment by attaching or painting a decorative sheet of the same color as the passage door holding frame 20A.
The height dimension of the passage door 30 in the vertical direction is made smaller than that of the above example so as not to interfere with the extension portion 22d. Instead of this embodiment, a notched recess for receiving the extension portion 22d may be provided at the corner of the lower end of the passage door 30 on the door tail side.
When such an extension portion 22d is provided, instead of or in addition to the configuration in which a suction portion 34 is provided on the trailing end face of the passage door 30, a configuration in which a suction portion is provided at the lower end of the passage door 30 and an attracted portion is provided on the extension portion 22d may be used.

The sliding door device B is provided with one fixed pin-shaped guide member 7A instead of the first guide member 7 and the second guide member 8 made of the above-mentioned magnet guides. This guide member 7A may be configured to include a fixed plate fixed on the floor and a pin-shaped guide portion 7Aa fixedly provided so as to protrude upward from the fixed plate. In the case where the fixed pin-shaped guide portion 7Aa is provided in this manner, the groove depth of the guide groove 14 including the groove portion 22e and the recess 22c may be made larger than the above example, and may be, for example, about 10 mm to 20 mm.
In the installation structure of the sliding door device B according to this modified example, the guide member 7A is configured so that its guide portion 7Aa is always positioned in the guide groove 14 including the groove portion 22e and the recess 22c of the door panel 1A that moves between the closed position and the fully open position. The guide member 7A is provided so that its guide portion 7Aa is positioned at the door tail end of the guide groove 14 of the door panel 1A in the closed position, and at the door tip end of the groove portion 22e of the extension portion 22d of the door panel 1A in the fully open position. In the illustrated example, the guide member 7A is provided so as to be positioned between a pair of intermediate vertical frames 45, 45 that define the door pocket opening. In this case, the door pocket inspection hatch 5 and the cover body 6 may not be provided.

In this modified example and the above example, the pet passage opening 29 is provided so as to open to the door end side and the lower side, but the pet passage opening may be provided so as to open only to the door end side. In this case, for example, the above-mentioned extension portion 22d may be provided so as to reach the door end side end of the panel body 10.
In this modified example and the above example, the upper cover part 21 and the trailing edge cover part 22 are provided, but they may not be provided. In this case, the bearing parts 24, 26 on both sides may be provided in appropriate positions.
In this modified example and the above example, a suction portion 34 is provided on the trailing end surface of the passage door 30, and an attracted portion 23 is provided on the side surface of the pet passage opening 29, but these may not be provided.
In this modified example and the above example, the door panels 1, 1A are shown installed in the door pocket, but they may also be installed in the sleeve wall or in various other installation configurations.
In this modified example and the above example, the guide groove 14 is provided at the lower end of the panel body 10, but a configuration in which such a guide groove 14 is not provided may also be used.
In this modified example and the above example, the door panel 1, 1A is configured to be suspended and held on the upper rail 41, but it may also be a bottom-loaded type in which a rolling body such as a wheel or caster that runs on the running object is provided on the lower end side of the door panel 1, 1A.

7 and 8 are diagrams illustrating an example of a door panel according to the second embodiment and an example of a door device including the door panel.
In this embodiment, the door panel 1B is different from the above-mentioned example mainly in the configuration of the panel body 10A and the through door holding frame 20B as shown in Fig. 7. In this embodiment, the door device is a hinged door device C. In other words, the door panel 1B constitutes a hinged door panel. The hinged door device C may include a door frame having an upper frame 40A, a door end side vertical frame 42A, and a hanging side vertical frame 44A.
The panel body 10A is shaped like a two-sided frame with a mirror panel portion 16 provided between vertical frame portions 15A, 15A on both sides in the door width direction.
The vertical frame parts 15A, 15A on both sides in the door width direction are generally rectangular flat plates that are long in the door height direction. These vertical frame parts 15A, 15A are provided over the entire panel body 10A in the door height direction. In the illustrated example, the width dimensions of these vertical frame parts 15A, 15A are generally the same. In other words, the end plate part 16 is provided so as to be located approximately in the center of the panel body 10A in the door width direction.

Handles 11A are provided on both sides of the vertical frame 15A on the door end side in the door thickness direction to be operated when opening and closing the door panel 1B.
