Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinged door for a house.

[0002]

2. Description of the Related Art Due to the westernization of life in recent years, doors of the door type have been widely used as residential doors instead of sliding doors. As shown in FIGS. 9 and 10, the hinged door 11 is attached to a frame 9 of a door opening 8 via a hinge 10, and can be freely opened and closed in one or both directions. The hinged door 11 has advantages that it can be opened and closed with a small force and is excellent in airtightness as compared with a sliding door.

[0003]

However, on the other hand, the conventional hinged door type 11 has the following disadvantages (1) to (4).
Has the following disadvantages. (1) Dead space is required. 9 and 10
As shown in FIG. 5, a so-called dead space D is formed in a locus portion where the door 11 opens and closes, and when footwear W such as shoes and slippers is placed in the dead space D, the door 11 pays the footwear W when the door is opened and closed. And the footwear W becomes an obstacle. Further, in some cases, the footwear W may be placed on the floor F and the door 11.
There is also a situation in which the footwear W is sandwiched between the lower end and the opening and closing of the door 11 is hindered, or the sandwiched footwear W is damaged. Therefore,
As the name suggests, nothing could be put in the dead space D including the footwear W. Therefore, footwear W is
The dead space D must always be kept away from the dead space D. For example, in the case of a toilet door, the user walks on the floor F in the dead space D of the door with bare feet or straddles the dead space D with a fork. As a result, they had to wear toilet slippers, which was unsanitary and caused the slippers to be scattered.

(2) A step is required. In order to eliminate the dead space D, it is necessary to provide a step by lowering the floor of the door in the opening direction by about 100 to 150 mm from the other floor. By doing so, the footwear W does not get caught on the door when the door is opened and closed, so that it is often used in toilets and the like. However, providing steps is a means of countering the recent barrier-free movement of eliminating steps in the house and ensuring the safety of the elderly and the disabled, and falls over the steps. And the danger increases. In addition, it is extremely difficult for a person using a wheelchair to pass through this step.

[0005] (3) In the case of a front door that opens outward, there are security and security problems. In the case of entrance doors, in a detached house, if there is sufficient space at the entrance, it is possible to provide an inward-opening door where the hinge is not exposed to the outside, but in the case of small houses and apartments In general, entrance space is limited, so the entrance door must be opened outward. When the entrance door is opened outward, the hinge holding the door is inevitably exposed outside. By removing the hinge mandrel exposed outside, the door can be removed, which poses a security problem. Also, in an apartment house with a common corridor, the door opening outside may collide with a pedestrian in the common corridor, which is a safety problem.

(4) There is a problem in appearance. Instead of providing a step, the lower end of the door may be cut by the height of the footwear W (about 10 cm) so that the footwear W is also used as a ventilation hole so that the footwear W is not caught at the time of opening and closing. However, this is inferior in appearance, and in the case of a toilet door, it is difficult to adopt it because odor and excretion sound leak. In addition, the means of using sliding doors as in the conventional method is also reconsidered, but for example, if a sliding door is used in a place where doors of the door type are lined up like a common hallway in an apartment complex, the design differs only there . Further, as described above, the sliding door is slightly opened and closed, has poor airtightness, and easily emits odors and excretion sounds. Furthermore, if the above-mentioned step is provided in a part of an apartment house, the height of the door is different only in that part, which is unsightly.

Therefore, an object of the present invention is to provide a housing which does not form a so-called dead space, can be opened and closed without interfering with footwear without providing a step, and is excellent in crime prevention, safety and appearance. To provide a door for use.

The vehicle includes a door body 2, a lifting / lowering body 3, a driving mechanism 4, a handle lever 5, a sensing mechanism 6, and a driving circuit C. The door body 2 has a hinge 1 attached to a frame 9 attached to the door opening 8.
The lifting body 3 is rotatably coupled to the door body 2 and is fitted to the lower end of the door body 2 so as to be vertically movable.
It has a width and a thickness substantially equal to. Therefore, the door main body 2 and the elevating body 3 are recognized as an integral body from the appearance.

The driving mechanism 4 is built in the door main body 2 and moves the elevating body 3 up and down. The drive mechanism 4 in the present embodiment includes a solenoid 4a operated by the handle lever 5 or the sensing mechanism 6, and a hydraulic cylinder 4c operated by a hydraulic pump 4b using the solenoid 4a as a switch source. The drive mechanism 4 in this embodiment uses a drive power source that is obtained by transforming a 100 V commercial power supply to 24 V by the power supply unit 7. The handle lever 5 is attached to a left intermediate height portion of the door body 2.

When the handle lever 5 is manually turned in the door opening direction, the drive circuit C operates the drive mechanism 4 to move the elevating body 3 upward, and the sensing mechanism 6 causes the door body 2 to move.
Is closed to detect the proximity of the door opening 8, the drive mechanism 4 is operated to move the lifting / lowering body 3 downward, and when the sensing mechanism 6 is not detected, the drive mechanism 4 is operated to raise the lifting / lowering body 3 It is designed to be moved. Specifically, the drive circuit C includes a first switch SW1 and a second switch SW2 connected in parallel between the power supply and the drive mechanism 4, and the first switch SW1 moves in the door opening direction of the handle lever 5. The second switch SW2 is turned on when the handle lever 5 is returned, turned off when the handle lever 5 returns, and turned on when the sensing mechanism 6 is not detected, and turned off when detected.

As shown in FIG. 8, the driving mechanism 4 includes a motor 4d operated by a handle lever 5 or a sensing mechanism 6, and a lifting shaft 4f which moves up and down by meshing with a gear rotated by the motor 4d. It can also be configured. Further, a pneumatic cylinder can be used instead of the hydraulic cylinder 4c,
It is also possible to use a long-stroke solenoid instead of a cylinder.

The sensing mechanism 6 is constituted by a door stop switch attached to the door main body 2. When the door main body 2 is opened and detached from the door opening 8, the second switch SW2 of the drive circuit C is opened. Is turned on, and the elevating body 3

Is turned on.

The housing door 1 according to the embodiment of the present invention comprises:
It works as follows. When the handle lever 5 is rotated clockwise to open the house door 1 in the closed state (see FIGS. 2 and 3), the first switch SW1 of the drive circuit C linked to the handle lever 5 is turned on. The drive circuit C for operating the drive mechanism 4 is energized, and the solenoid 4a
Operates, and the rod moves in one direction. The hydraulic pump 4b is operated by the rod of the solenoid 4a,
A hydraulic pressure is generated in each of the two hydraulic cylinders 4c through one hydraulic pipe. As a result, the lifting body 3 connected to the rod of the hydraulic cylinder 4c rises, and the opening space S (10
(About 0 mm to 150 mm) (see FIGS. 4 and 5).

When the door 1 is further opened in this state, the door stop switch constituting the sensing mechanism 6 is detached from the door opening 8. As a result, the second switch SW2 linked to the door stop switch is turned on, the energized state of the drive circuit C is maintained, and the ascending posture of the elevating body 3 is maintained as it is. Note that, at this time, even if the ascent / descent body 3 continues to move upward and the handlebar 5 is returned to the original position and the first switch SW1 is turned off, the drive circuit C is energized by the second switch SW2. Therefore, the upward movement is continued as it is, and the open space S is formed.

By forming such an open space S, when the door 1 is opened, the lower end thereof does not interfere with the footwear W, and a so-called dead space D is not formed. In addition, since there is no need to provide a step for eliminating the dead space D, it is possible to contribute to the construction of a barrier-free house. Further, when used as an entrance door, the door can be opened inward, so that when the door 1 is opened, it is safe from hitting a person walking outside, and the hinge 10 of the door 1 is closed. Since it is provided inside, there is no problem in crime prevention such that the stem of the hinge 10 is removed from the outside.

As a result, the second switch SW2 is turned off, and the solenoid 4a
Moves in the opposite direction, and the hydraulic pressure in the opposite direction acts on the hydraulic cylinder 4c from the hydraulic pump 4b via the other hydraulic pipe. Therefore, the rod of the hydraulic cylinder 4c extends, and the elevating body 3 connected to the distal end thereof is extended.
Descends, and the open space S is closed. In a state where the door stop switch is operated, the handle lever 5 is normally returned to the original position, and the first switch SW1 is already off. Therefore, the door stop switch is set to the door opening 8.
And the second switch SW2 is turned off, so that the elevating body 3 descends (see FIGS. 2 and 3).

When the door 1 is closed, the elevating body 3 is in the descending posture, and the distance between the lower end of the elevating body 3 and the floor surface F is 3 to 3.
It is about 5 mm. Therefore, the appearance is not different from a normal door. By setting the distance between the lower end of the elevating body 3 and the floor surface F to be about 5 to 20 mm when the door is closed, the space can be made a ventilation hole having no security problem. This ventilation hole is particularly effective in summer.
