Description

The present invention relates to a fixture with a door body that moves in the longitudinal direction of the upper frame.

In a top-hung sliding door, which is a type of fitting, the door body's suspension wheel moves along a rail in the upper frame, and the door body moves in the longitudinal direction of the upper frame. The rail is located in a groove that opens downward in the upper frame, and the upper end of the door body is placed in the groove in the upper frame. In the internal space of such a groove in the upper frame, animals (for example, birds such as sparrows) may enter the area above the door body and build nests inside (for example, on the rail).

Regarding the prevention of nesting in building materials, Patent Document 1 describes a window shutter opening concealment device that uses a concealing plate attached to the opening of the upper storage case to hide the gap between the opening and the shutter, preventing small birds from entering the gap. However, the opening concealment device described in Patent Document 1 is a device that prevents small birds and other birds from entering the upper storage case that stores the shutter, and cannot prevent animals from entering the grooves of the upper frame. Furthermore, if an animal enters the upper storage case from a location other than the gap between the opening and the shutter, it cannot prevent nesting in the internal space of the upper storage case.

The second partition 52 is arranged with a gap (here, a gap of a size that animals cannot enter) between it and the groove bottom 32, and faces the groove bottom 32 in the vertical direction. The second partition 52 is located between the upper end 3A of the door body 3 and the groove bottom 32, and divides the internal space 35 of the groove 30 in the vertical direction.

The pair of third partitions 53 are a pair of side surfaces (side partitions) of the partition member 50, and protrude from the first partition 51 toward the second groove wall 34 of the groove 30. The third partitions 53 are spaced apart from each other in the longitudinal direction R of the upper frame 5, protrude from the first partition 51 toward the indoor side, and are disposed between the second partition 52 and the upper end 3A of the door body 3. The third partitions 53 are located at both ends of the partition member 50, on the indoor side (the second groove wall 34 side) of the first partition 51 and below the second partition 52 (the upper end 3A side of the door body), and divide the internal space 35 of the groove 30 in the longitudinal direction R of the upper frame 5.

The tip of the second partition 52 on the indoor side (the second groove wall 34 side) is bent downward, and the second partition 52 has a hanging portion 54 formed at its tip. The hanging portion 54 protrudes downward and hangs down at the tip of the second partition 52. The indoor side tips of the pair of third partitions 53 are formed in a bent shape with a step corresponding to the bent shape of the second groove wall 34. The tip of the second partition 52, the hanging portion 54, and the tip of the third partition 53 are each positioned with a gap (here, a gap of a size that animals cannot enter) between them and the second groove wall 34, and face the second groove wall 34 in the forward direction S of the upper frame 5.

The partition member 50 defines a partition space 55 between itself and the second groove wall portion 34 by the partition portions 51-53. The partition space 55 is part of the internal space 35 of the groove portion 30, and is formed between the partition portions 51-53 of the partition member 50 and the second groove wall portion 34, and is surrounded by the partition portions 51-53 and the second groove wall portion 34. The base member 40 is disposed in the partition space 55, and is located on the indoor side of the first partition portion 51 and below the second partition portion 52. The base member 40 is also located between the pair of third partition portions 53. The reinforcing portion 43 of the base member 40 is located below the rail 21, separated from the pair of third partition portions 53.

The rail 21 is disposed in the partition space 55 where the partition member 50 is located. The first partition 51 is disposed on the outdoor side (first groove wall 33 side) of the partition space 55 and the rail 21, and covers the rail 21 from the outdoor side. The second partition 52 is disposed above the partition space 55 and the rail 21, and covers the rail 21 from above. The first partition 51 is disposed between the first groove wall 33 of the groove 30 and the rail 21, and the second partition 52 is disposed between the groove bottom 32 of the groove 30 and the rail 21.

The rail 21 protrudes from the second groove wall 34 of the groove 30 to the outdoor side and is positioned on the indoor side of the first partition 51. The outdoor tip of the rail 21 is positioned with a gap between it and the first partition 51 (here, a gap of a size that animals cannot enter), and faces the first partition 51 in the forward direction S of the upper frame 5. The rail 21 is located below the second partition 52 and is positioned between the second partition 52 and the upper end 3A of the door body 3.

The pair of third partitions 53 have a void 56 for the rails 21 in which the rails 21 are arranged. The void 56 is formed in the middle of the third partition 53 in the vertical direction, and the third partition 53 is divided into upper and lower parts at the void 56. The rails 21 penetrate the void 56 of the third partition 53 in the longitudinal direction R of the upper frame 5 and extend in the longitudinal direction R of the upper frame 5. The third partition 53 is arranged with a gap (here, a gap of a size that an animal cannot enter) between it and the rails 21 in the void 56.

The third partitions 53 are located above and below the rail 21, and are disposed between the rail 21 and the second partition 52, and between the rail 21 and the upper end 3A of the door body 3. When the door body 3 moves, the third partitions 53 move in the longitudinal direction R of the upper frame 5 without contacting the rail 21. In addition, the pair of third partitions 53 are disposed between the upper end 3A of the door body 3 and a gap 57 for the wiring 11 in which the wiring 11 of the door body 3 can be disposed. When the wiring 11 is disposed at the upper end 3A of the door body 3 at the location where the third partitions 53 are located, the wiring 11 is disposed in the gap 57. The gap 57 is located in the arrangement path of the wiring 11 and allows the wiring 11 to pass through. The third partitions 53 do not contact the wiring 11 in the gap 57, and form a gap between the wiring 11 and the third partitions 53.

When installing the door body 3 on the fixture 1, the cover 20 is removed from the upper frame 5, and the groove 30 of the upper frame 5 is opened toward the outdoors. The base member 40 of the nesting prevention device 9 is also attached to the upper end 3A of the door body 3 in advance. In this state, the door body 3 is moved from the outdoors toward the frame body 4, and the hoist 10 of the door body 3 is placed on the rail 21 and connected. Next, the partition member 50 of the nesting prevention device 9 is attached to the base member 40 from the outdoors, and the cover 20 is attached to the upper frame 5. As a result, the nesting prevention device 9 is positioned in the internal space 35 of the groove 30.

In the fitting 1 described above, the partitions 51-53 of the partition member 50 within the groove 30 of the upper frame 5 can prevent animals from entering between the upper frame 5 and the partition member 50. The partitions 51-53 can also prevent animals from entering the partition space 55. This can prevent animals from entering the groove 30 of the upper frame 5, and can prevent animals from building nests in the internal space 35 of the groove 30.

As the door body 3 moves, the partition member 50 moves in the longitudinal direction R of the upper frame 5 in the internal space 35 of the groove portion 30. Therefore, nesting in the internal space 35 of the groove portion 30 can be prevented at the point where the partition member 50 moves. By providing a gap between the partition members 51-53 and the upper frame 5, it is possible to prevent interference with the movement of the door body 3. The nesting prevention device 9 can be retrofitted to the door body 3 of an existing fixture 1, and can be easily installed on the existing fixture 1.

The tip of the second partition 52 and the tip of the third partition 53 face the second groove wall 34 of the groove 30 with a gap between them. This prevents animals from entering between the second groove wall 34 and the partition member 50, and from entering the partition space 55, thereby suppressing nesting in the internal space 35 of the groove 30.

By arranging the rail 21 of the upper frame 5 in the void 56 of the third partition 53, nesting on the rail 21 can be prevented without interfering with the movement of the door body 3. The nesting prevention device 9 provided between the two hoists 10 can prevent nesting in the internal space 35 of the groove 30 between the two hoists 10 while preventing any influence on the movement of the hoists 10 along the rail 21.

The base member 40 of the nesting prevention device 9 allows the partition member 50 to be easily attached to the upper end portion 3A of the door body 3. The partition member 50 attached to the base member 40 can be changed to match the shape and dimensions of the groove portion 30 of the upper frame 5. This allows the nesting prevention device 9 to be easily attached to groove portions 30 of various shapes and dimensions.

When the door body 3 moves, the reinforcing portion 43 of the base member 40 can suppress the shaking of the mounting portion 42 of the base member 40 and the partition member 50, stabilizing the partition member 50. As a result, it is possible to prevent the nesting prevention device 9 from affecting the movement of the door body 3. By arranging the wiring 11 in the gap 57 between the third partition portion 53 and the upper end portion 3A of the door body 3, the wiring 11 can be easily arranged at the upper end portion 3A of the door body 3, and damage to the wiring 11 can also be suppressed.

The end of the second partition 52 may be opposed to the second groove wall 34 without providing the hanging portion 54 at the end of the second partition 52. The nesting prevention device 9 may also be provided at a location other than between the two hoisting wheels 10. For example, in addition to or instead of being provided between the two hoisting wheels 10, the nesting prevention device 9 may be provided outside the hoisting wheels 10 in the longitudinal direction R of the upper frame 5 (the door end 3C side, the door tail 3D side).

In this embodiment, one side of the projected direction S of the upper frame 5 is the outdoor side, and the other side of the projected direction S of the upper frame 5 is the indoor side. In contrast, one side of the projected direction S of the upper frame 5 may be the indoor side, and the other side of the projected direction S of the upper frame 5 may be the outdoor side. Furthermore, the present invention is not limited to single sliding doors installed at entrances, but can be applied to various building materials equipped with a door body that moves in the longitudinal direction of the upper frame.

As described above, the fixture is a fixture comprising an upper frame having a groove portion that opens downward, and a door body whose upper end portion is disposed within the groove portion and moves in the longitudinal direction of the upper frame,
A nesting prevention device is provided at the upper end of the door body, arranged in the groove, and partitions the internal space of the groove with a partition member,
The groove portion has a groove bottom portion located above an upper end portion of the door body, and a first groove wall portion and a second groove wall portion opposed to each other,
The partition member is a fitting having a first partition portion facing the first groove wall portion with a gap between them, a second partition portion protruding from the first partition portion toward the second groove wall portion and facing the groove bottom with a gap between them, and a pair of third partition portions protruding from the first partition portion toward the second groove wall portion with a gap between them in the longitudinal direction of the upper frame and positioned between the second partition portion and the upper end of the door body.
Therefore, in a fixture having a door body that moves in the longitudinal direction of the upper frame, it is possible to prevent animals from entering the groove portion that opens toward the bottom of the upper frame, and to prevent nesting in the internal space of the groove portion.

An end portion of the second partition portion on the second groove wall portion side and an end portion of the third partition portion on the second groove wall portion side face the second groove wall portion with a gap therebetween.
Therefore, animals are prevented from entering between the second groove wall portion and the partition member, and nesting in the internal space of the groove portion can be suppressed.

the upper frame has a rail protruding from the second groove wall portion toward the first groove wall portion within the groove portion and extending in a longitudinal direction of the upper frame,
The door body has a hoist attached to the upper end portion and supported by the rail so as to be movable in the longitudinal direction of the upper frame,
the first partition portion is disposed between the rail and the first groove wall portion,
the second partition portion is disposed between the rail and the groove bottom portion,
The third partition portion has a cavity portion in which the rail is disposed.
Therefore, nesting on the rail can be prevented without interfering with the movement of the door body.

The nesting prevention device is provided between two of the hoists which are spaced apart from each other in the longitudinal direction of the upper frame.
Thus, nesting in the internal space of the groove between the two wheels can be prevented while preventing any influence on the movement of the wheels along the rail.

The nesting prevention device has a base member attached to an upper end portion of the door body and placed in the groove portion,
The partition member is attached to the base member and is connected to the upper end of the door body by the base member.
Therefore, the partition member can be easily provided at the upper end of the door body by using the base member.

The base member has a base portion attached to the upper end portion of the door body, a mounting portion that protrudes upward from the base and to which the partition member is attached, and a reinforcing portion that is connected to the base and the mounting portion and reinforces the mounting portion.
Therefore, when the door body moves, the reinforcing part can suppress shaking of the mounting part and the partition member, stabilizing the partition member. As a result, it is possible to prevent the nest building prevention device from affecting the movement of the door body.

The door body has wiring arranged on the upper end portion,
The third partition portion is disposed between the upper end portion of the door body and a gap allowing the wiring to be disposed therethrough.
Therefore, by arranging the wiring in the gap between the third partition and the upper end of the door body, the wiring can be easily arranged at the upper end of the door body and damage to the wiring can also be suppressed.
