DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a watertight structure of a front door which is barrier-free and which ensures watertightness between a front door and a lower frame.

[0002]

2. Description of the Related Art When considering the entrance and exit of a wheelchair user from an entrance door, the actual room No. 1-7819 and actual climbing, as well as the space between the room sandwiching the door and the outdoor floor surface, are taken into consideration.
The problem is that there is no step on the upper surface of the lower frame as in 3002107.

[0003] An airtight material for ensuring watertightness cannot be laid between the lower frame having no step on the upper surface and the lower end of the one-sided door. Water tightness between the lower frame and the lower frame is ensured by an airtight material built into the bottom of the door lower frame as in the above example.

The airtight material built in the lower frame of the door rises and falls with the opening and closing of the door, protrudes from the lower frame when the door is closed, and comes into close contact with the upper surface of the lower frame. In that state, the airtight material is exposed to the outdoors. Deterioration becomes a problem because it is placed. In addition, when water falling along the surface of the door and falling around the lower surface of the lower frame hits the airtight material, the water may enter the room from between the airtight material and the upper surface of the lower frame due to a capillary phenomenon.

[0005] The present invention proposes a watertight structure that enhances the watertightness between the lower frame and the deterioration of the airtight material built in the lower frame of the door.

[0006]

According to the present invention, an airtight material incorporated in a lower frame of a door is composed of an airtight material body close to a room and a hanging piece adjacent to the outside of the room and hanging down from the airtight material body. And, by protecting the airtight material main body with the hanging piece, while preventing the deterioration of the airtight material main body, and preventing the water flowing around the lower surface of the lower frame from entering the room from the upper surface of the lower frame,
Increases water tightness with the lower frame.

[0007] The hanging piece of the airtight material projects downward from the lower end of the airtight material outside the room, so that the airtight material main body is placed in an exposed state, and water falling from the lower frame or bouncing on the lower frame. Prevents the airtight material main body from being applied to the airtight material main body and protects the airtight material main body from deterioration.

In addition, by preventing water from splashing on the airtight material main body and returning water from the outdoor side, water is prevented from entering between the airtight material main body and the upper surface of the anticipated piece, and the airtight material main body is used. Thorough water tightness with the prospective piece.

[0009] The upper surface of the lower frame is formed on a flat surface or a step or a slope within a range that can be regarded as a flat surface so that the wheelchair can move between the room and the outside without any trouble. To the extent that the inclination is not a problem, the outdoor upper surface where the outdoor hanging piece is in close contact is positioned at a slightly lower level than the indoor upper surface where the airtight material body closer to the indoor is in close contact with the lower end of the hanging piece. It is located at a level corresponding to the lower end of the airtight material body. Thereby, the airtight material main body and the hanging piece are brought into close contact with the upper surface of the lower frame with the same pressure, and the bending of the hanging piece caused by projecting downward from the lower end of the airtight material body is prevented.

[0010] By preventing the hanging pieces from being bent, protection of the airtight material body by the hanging pieces and ensuring of watertightness by the airtight material body are ensured.

In a second aspect of the present invention, a drain hole for discharging water existing on the lower frame is formed in the upper surface of the lower frame, the airtight material body is brought into close contact with the upper surface of the lower frame, and the hanging piece is positioned in the drain hole. In addition, water is prevented from entering between the airtight material main body and the upper surface of the lower frame while maintaining the close contact state between the airtight material main body and the upper surface of the lower frame, thereby ensuring watertightness.

Since the drain hole formed in the upper surface of the lower frame does not form a step or an inclination on the upper surface of the lower frame, the wheelchair can pass through the lower frame without hindrance by suppressing the width of the drain hole.

According to a third aspect of the present invention, the upper surface of the lower frame is divided into an indoor-side speculative piece and an outdoor-side speculative piece, and the level of the outdoor-side speculative piece is determined by the height of the grating adjacent to the outdoor side of the lower frame. By lowering the grating on the outdoor-side prospect piece of the lower frame, bringing the airtight material body into close contact with the upper surface of the indoor-side prospect piece, and bringing the hanging piece into close contact with the upper surface of the grating, as in claim 2, In this way, water is prevented from entering between the airtight material main body and the upper surface of the lower frame while maintaining the close contact between the airtight material main body and the upper surface of the lower frame, thereby ensuring watertightness.

Since the step between the indoor-side prospect and the outdoor-side prospect corresponds to the height of the grating, no step is generated between the upper surface of the indoor-side prospect and the upper surface of the grating. The wheelchair can pass on the lower frame without any trouble.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a door 1 as shown in FIG.
This is a watertight structure that secures watertightness with the prospective piece 5 of the lower frame 4.

As shown in FIGS. 1 and 7, a door bottom 6 is accommodated in the bottom of the lower frame 2, and an airtight material 3 is stored in the door bottom 6 such that the door 1 can be opened and closed and moved up and down. As shown in FIG. 7, the door bottom 6 is built in the door bottom 6 as shown in FIG. 8 by the rod 7 projecting toward the vertical frame 8 on the hanging side when the door 1 is opened and hitting the vertical frame 8 when closed. The airtight material 3 is lowered against the spring, and when the rod 7 is separated from the vertical frame 8, the airtight material 3 is raised and stored by the restoring force of the spring.

The hermetic member 3 is composed of a hermetic member main body 30 closer to the room and a hanging piece 31 adjacent to the outside of the room and hanging down from the lower end of the hermetic member main body 30. The hanging piece 31 is formed by making a cut in the outside of the airtight material 3 integrally molded,
Alternatively, it is formed by combining an airtight material separate from the airtight material main body 30.

According to the first aspect of the present invention, as shown in FIG.
The upper surface where the hanging piece 31 close to the outdoor is in close contact is positioned at a level corresponding to the lower end of the airtight material body 30 and the lower end of the hanging piece 30, respectively, so that the airtight material body 30 and the hanging piece 31 are evenly arranged on the upper surface of the prospective piece 5. It is adhered to.

The portion of the upper surface of the prospective piece 5 where the airtight material body 30 is in close contact and the portion where the hanging piece 31 is in close contact with the airtight material body 30
When there is a level difference corresponding to the level difference between the lower end of 30 and the lower end of the hanging piece 31, and when the prospective piece 5 forms a horizontal plane, as shown in FIG. Thus, a step is formed between the upper surfaces of the outdoor-side prospect pieces 52 to which the hanging pieces 31 are in close contact. If the entire prospect piece 5 does not form a horizontal plane, the upper surface of the prospect piece 5 simply slopes gently downward from the indoor side to the outdoor side.

The level difference between the part of the prospective piece 5 where the airtight material body 30 is in close contact and the part where the hanging piece 31 is in close contact is large enough to allow a wheelchair to pass over the prospective piece 5 without any trouble. , The upper surface of the indoor side prospect piece 51 and the outdoor side prospect piece
The step between the tops of 52 is negligible for wheelchair traffic 3
It can be suppressed to the size range of about mm.

The level of the lower end of the airtight material main body 30 and the lower end of the hanging piece 31 is determined according to the size of the allowable step, and there is a step of 3 mm between the indoor-side prospect 51 and the outdoor-side prospect 52. In this case, the hanging piece 31 projects downwardly by about 3 mm from the airtight material body 30, and the airtight material body 30 and the hanging piece 31 are in close contact with the indoor-side prospect piece 51 and the outdoor-side prospect piece 52, respectively, at the same pressure.

According to the second aspect of the present invention, as shown in FIGS. 2 and 3, a drain hole 53 is formed in the prospective piece 5, the airtight material main body 30 is brought into close contact with the upper surface of the prospective piece 5, and the hanging piece 31 is connected to the drainage hole 53. The watertightness between the airtight material main body 30 and the prospective piece 5 is ensured by being positioned inside.

The lower frame 4 has a cross section having a drain 54 below the prospective piece 5 for receiving water dropped from the drain hole 53, and water is discharged outside the lower frame 4 outside the drain 54. A drain hole 55 for draining is formed. The drain hole 53 is provided with a mesh-shaped cover 9 for preventing dust from falling into the drain passage 54.

The drain hole 53 of the prospective piece 5 is continuous in the longitudinal direction of the lower frame 4 in correspondence with the airtight material 3 continuing in the longitudinal direction of the lower frame 2. It is divided into the indoor side prospect piece 51 and the outdoor side prospect piece 52 with the hole 53 interposed therebetween. The width of the drain hole 53 is suppressed to a size that does not allow the wheel of the wheelchair to fall.

FIG. 2 shows an indoor-side prospect piece 51 and an outdoor-side prospect piece.
FIG. 3 shows a case where 52 is on the same surface, and FIG. 3 shows a case where there is a step.

According to the third aspect of the present invention, when the grating 10 is adjacent to the outdoor side of the lower frame 4 as shown in FIGS. The airtight material body 30 is brought into close contact with the grating 10
And the watertightness between the prospective pieces 5.

There is a step corresponding to the height of the grating 10 between the indoor-side prospect piece 51 and the outdoor-side prospect piece 52 of the prospect piece 5, and the grating 10 is placed on the outdoor-side prospect piece 52. FIG. 4 shows an example of the installation of the grating 10 when the lattice material 11 of the grating 10 faces the expected direction of the lower frame 4, and FIG. 5 shows an example of installation of the grating 10 when the lattice material 11 is parallel to the lower frame 4.
Is in close contact with the upper surface of the indoor side projection piece 51, and the hanging piece 31 is in close contact with the upper surface of the grating 10.

Since the lower end of the hanging piece 31 is lower than the lower end of the hermetic material body 30, the level of the upper surface of the grating 10 is lower than the upper surface of the indoor side projection piece 51 of the lower frame 4 in each of FIGS. However, for example, in the case of FIG. 5 where the grid material 11 of the grating 10 is arranged in parallel with the lower frame 4, the hanging piece 31 is
If the arrangement of the grid member 11 is set so as to be in close contact with the side surface of the eleventh side, the hanging piece 31 will not be bent even if the level of the upper surface of the indoor side projection piece 51 and the upper surface of the grating 10 are the same.

In the present invention, the water falling on the lower frame 4 by the hanging piece 31 is dropped on the outdoor prospect piece 52. However, since the outdoor side of the outdoor prospect piece 52 is open, the water is grating. You will be led to the 10 side. Although garbage also accumulates on the outdoor-side prospect piece 52, cleaning can be performed by lifting the grating 10.

[0030]

According to the present invention, the airtight material main body is protected by the hanging piece formed near the outdoor of the airtight material main body incorporated in the lower frame, so that the deterioration of the airtight material main body can be prevented. Further, since the hanging pieces prevent water existing on the lower frame from entering the room from the upper surface of the lower frame, the watertightness between the airtight material and the lower frame is improved.

In the first aspect of the present invention, the upper surface of the lower frame, to which the hanging piece closer to the outside is in close contact, is located at a level slightly lower than the upper surface of the indoor side, to which the airtight material body is in close contact. While allowing traffic to pass without difficulty,
The bending of the hanging piece can be prevented, and the protection of the airtight material body by the hanging piece and the securing of watertightness by the airtight material body can be ensured.

In the second aspect, the airtight material main body is brought into close contact with the upper surface of the lower frame, and the hanging piece is positioned in the drain hole formed in the upper surface of the lower frame. While preventing water from entering between the airtight material main body and the upper surface of the lower frame, the watertightness is improved.

According to a third aspect of the present invention, a step corresponding to the height of the grating is formed on the upper surface of the lower frame, the grating is placed on the outdoor-side prospect piece of the lower frame, and the airtight material body is brought into close contact with the upper surface of the indoor-side prospect piece. Since the hanging piece is brought into close contact with the upper surface of the grating, it is possible to prevent water from entering between the airtight material body and the upper surface of the lower frame while maintaining the close contact between the airtight material body and the upper surface of the lower frame.

According to the second aspect, a step is not formed on the upper surface of the lower frame even by the drain hole formed on the upper surface of the lower frame. In the third aspect, the height difference between the indoor side prospect piece and the outdoor side prospect piece is the height of the grating. Therefore, a step is not generated between the upper surface of the indoor side prospect piece and the upper surface of the grating, and there is no obstacle to the passage of the wheelchair.
