DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art As a door bottom gap closing device, a partition material for closing a gap between a door bottom and a shoe rub is attached to a door lower frame so as to be able to come out toward the shoe rub, and a vertical frame is attached to a hinged door vertical frame. When the push button is pushed into the door vertical frame by receiving the reaction force from the vertical frame that hits the door vertical frame when opening and closing by the push button that is attached to the Known is one that is extruded toward the rub so that the gap between the door bottom and the shoe rub is closed.

[0003]

This known door bottom gap closing device is adapted to be attached when a door is manufactured, and various types of door bottom gap closing devices are prepared according to door specifications. It cannot be applied to ready-made doors, and because it is mounted in a narrow space called the lower frame of the door, the mechanism is fine and complicated, the cost is high, and the vibration of the door causes It is easily damaged and difficult to handle and maintain, and mounting it causes problems such as making the entire door heavier.

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

[0005]

That is, a door bottom gap closing device 20 according to the present invention is attached to a shoe rub of a door frame fixed to a passage, and is provided with a groove member 12 having a straight groove 11 extending straight. At the left and right ends, a pair of left and right swing levers 13 and 14 that swing at right angles to the longitudinal direction of the long groove 11 are provided, and a support shaft is provided between the swing levers 13 and 14 in parallel with the swing shaft 15. 16, a partition member 17 having substantially the same length as the support shaft 16 is hung on the support shaft 16 so that the upper edge 18 can be rotated in parallel with the swing shaft 15, and fitted into the long groove 11 so as to protrude and retract. One end 19 of one swing lever 13 protrudes above the long groove to form a door stop (19), and the dimension of the partition member 17 in the depth direction of the groove is adjusted by the swing of the door stop 19 to form an upper edge 18 of the partition member 17. Of a size required to protrude from the long groove 11 A.

Hereinafter, as specifically described 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 part.

The partition member 17 is made of an airtight and extremely lightweight member such as expanded polystyrene or expanded polyethylene as a main material, and has a horizontally elongated slot 2 penetrating in its length direction.
3 is open.

The support shaft 16 is loosely fitted in the elongated hole 23. When the swing lever 13 swings and rotates, the support shaft 16 swings up and down. The partition member 17 is guided by the groove wall 29 like a follower of a cam mechanism having the groove wall 29 as a cam surface, is pushed up, and comes out of the long groove 11.

Therefore, the partition member 17 is thus formed by the groove wall 29.
It is not always necessary to loosely fit the support shaft 16 into the long hole 23 opened in the partition member 17 as long as the necessary relative rotational movement is possible when it is guided up and pushed up and out of the long groove 11. For example, the long groove 1 is formed on the side surface 24 of the partition member 17.
1, a support shaft 16 can be loosely fitted in the groove, or a bracket having a horizontally long slotted hole is attached to the bottom surface of the partition member 17, and the bracket is supported in the slotted hole. The shaft 16 can be loosely fitted, or the partition member 17 and the support shaft 16 can be connected so that relative rotational movement occurs by bringing the support shaft 16 into rolling contact with the bottom surface of the partition member 17. .

The left and right swing levers 13 and 14 are provided on the swing shaft 1.
5 are bonded to each other so as to swing together, but they are not bonded to the swing shaft 15 but are pin-joined, and the left and right swing levers 13 and 14 are integrated via the support shaft 16. It can also be made to oscillate.

The door stop 19 is elastically urged by a leaf spring (not shown) and vertically protrudes above the long groove 11.

The door bottom gap closing device 20 is attached to the shoe rub at the entrance, and in the figure, 25 is a door, 26 is a vertical frame, 27 is a door stop, and 28 is a corridor.

The lower end of the door 25 to be closed is
, The swinging lever 13 swings and rotates, and the partition member 17 is protruded from the elongated groove 11. The lower end of the door 25 abuts against the door stop 19 due to the door 2.
5 is closed and positioned above the shoe rub (21, 22), so that the pushed up partitioning material 17 is
0 and crimped, so that the gap 31 between the door bottom 30 and the shoe rub (21, 22)
Will be blocked.

On the other hand, when the door 25 is opened, the door stop 19 is elastically urged by a leaf spring (not shown) to return to the original vertical state.
14 and the support shaft 16 also oscillate and return to the original state,
7 falls into the long groove 11.

Therefore, when the door 25 is open,
It does not occur that the partition member 17 protrudes above the shoe rub (21, 22) and hinders walking.

In this case, a leaf spring is used to return the door stop 19 to the original vertical state. However, the swing lever 13 swings and rotates due to the gravity of the door stop 19. In order to return the door stop 19 to the original vertical state, a leaf spring is not necessarily required. Instead, a coil spring, a rubber plate, an air cushion, or the like is applied. You can do it.

[0017]

As described above, since the door bottom gap closing device 20 according to the present invention is installed in the shoe rub (21, 22), the space for installing the door bottom gap closing device 20 is particularly increased. This is not necessary, and the door bottom gap closing device 20 can be configured to be larger than the thickness of the door 25, and it is not necessary to make it compact, so the door bottom gap closing device 20 is configured by a simple mechanism. The manufacturing cost of the door bottom gap closing device 20 can be reduced,
It is easy to maintain and can be used for various types of doors without being damaged by the vibration of the doors.
