JPH0626278A - Bottom gap closing device for floor mounted door - Google Patents

Abstract

PURPOSE:To provide a door bottom gap closing device between the door sills of a doorway, and not at the restricted lower space of a door. CONSTITUTION:The end of a channel steel 12 having a long channel 11 is fitted with a division 17 driven with an oscillation lever 13 capable of oscillation and rotation in a direction orthogonal with the lengthwise direction of the channel 11 for the closure thereof. In state where the division 17 closes the channel 11, the forward end (19) of the lever 13 forms a door stop section 19 projected above the channel 11. In addition, the end 19 is so constituted as to form a door sill in state where the division 17 closes the channel 11. When the lower end of a closed door 25 comes in contact with the door stop section 19, the oscillation lever 13 vibrates and the division 17 is caused to collide with a door bottom 30, thereby closing a gap 31 between the bottom 30 and door sills 21 and 22. A door bottom gap closing device 20 is provided at the door sill of a doorway and, therefore, not limited in size. Thus, this device 20 can be used for various doors of different type.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door bottom gap sealing device for closing a gap formed between a door bottom of an entrance and a door and shoe rubs.

[0002]

2. Description of the Related Art As a door bottom gap sealing device, a partitioning material for closing a gap between a door bottom and a shoe rub is attached to a lower door sash so that it can be retracted and retracted toward the shoe rub, and a vertical frame is attached to a door vertical sill equipped with a hinge. When the push button is attached so that it can be retracted toward and away from the door, when the push button receives the reaction force from the vertical frame that the door vertical frame hits when opening and closing, and is pushed into the door vertical frame, the partitioning material is removed from the lower frame of the shoe. It is known that a member is extruded toward the rubbing to close the gap between the door bottom and the shoe rub.

[0003]

This known door bottom gap sealing device is designed to be installed when making a door, and various types of door bottom gap sealing devices are prepared according to the standard of the door. It has to be installed in a narrow space called the lower frame of the door because it cannot be applied to an off-the-shelf door, and the mechanism becomes fine and complicated, the cost is high, and the vibration of the door causes There is a problem that it is easy to get rid of, it is difficult to handle and maintain, and the whole door becomes heavy by attaching it.

Therefore, the present invention provides a door bottom gap sealing device,
The above problem is sought to be solved by providing the shoe rubbing instead of the door.

[0005]

That is, a door bottom gap sealing device 20 according to the present invention is to be attached to a shoe rub of a door frame fixed to a passage, and includes a groove member 12 having a straight long groove 11. A partition member 17 that is driven by a swing lever 13 that swings and rotates orthogonally to the length direction of the long groove 11 to open and close the long groove 11 is attached to the end portion.
When the long groove 11 is closed, the tip end portion (19) of the rocking lever 13 protrudes to the upper side of the long groove 11.
9, and the partition member 17 forms a shoe rub when the long groove 11 is closed.

As will be specifically described below with reference to the drawings, both groove edges 21 and 22 of the long groove 11 project at right angles to the groove depth direction to form a shoe rubbing portion.

The partition member 17 is composed mainly of an airtight, extremely lightweight and elastic member such as expanded polystyrene or expanded polyethylene, and is attached to the swing shaft 15 joined to the swing lever 13. It is carried.

A support plate 14 projects from the groove wall 18 so as to cover the long groove 11, and a partition plate 17 is received by the support plate 14 when the long groove is closed.

The side edge of the partition plate 17 on the swing shaft side is the support plate 14.
Sticks out below.

The door stop 19 is maintained vertically by the leaf spring 16.

In the figure, 25 is a door, 26 is a vertical frame, 27 is a door stop, and 28 is a corridor.

That is, the door bottom gap sealing device 20 is attached to the shoe rub at the entrance / exit, and when the lower end of the door 25 to be closed hits the door stop 19, the partition plate 17 swings and rotates together with the swing lever 13. When the long groove 11 is opened and the door is opened, the partition plate 17 closes the long groove 11 by being elastically biased by the leaf spring 16 and the door contact portion 19 returns to the vertical state.

As described above, the lower end of the door 25 has the door stop 19
The one that hits the shoe is when the door 25 is closed and the shoe rub (21.
22), the partition plate 17 that is oscillated and rotated together with the door stop 19 and protrudes comes into contact with the door bottom 30, and the gap between the door bottom 30 and the shoe rubs (21, 22). 31
Will be blocked.

On the other hand, when the door 25 is opened, the door stop 19 is elastically urged by the leaf spring 16 and returns to the original vertical state. At that time, the partition member 17 is also moved together with the swing lever 13. After returning to the original state, the long groove 11 is closed to form shoe rubs.

Therefore, when the door 25 is open,
The partition member 17 does not protrude above the shoe rubs (21, 22) and hinder walking.

In this case, the leaf spring 16 is used to return the door stop 19 to the original vertical state, but the swing lever 13 swings and rotates due to the gravity of the door stop 19. Then, the leaf spring 1 is returned to the original state.
6 is not always necessary, and a coil spring, a rubber plate, an air cushion, or the like can be applied instead.

[0017]

As described above, since the door bottom gap sealing device 20 according to the present invention is installed on the shoe rubs (21, 22), the space for installing the door bottom gap sealing device 20 is particularly improved. It is not necessary, and the door bottom gap sealing device 20 can be configured to be thicker than the thickness of the door 25, and it is not necessary to make it compact. Therefore, the door bottom gap sealing device 20 is configured by a simple mechanism. Also, the manufacturing cost of the door bottom gap sealing device 20 is cheap,
It is easy to maintain, and it can be used for various types of doors without being damaged by the vibration of the doors, and can be easily installed and installed at the construction site.
