Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rotary support for a door that can automatically close the door by gravity.

(Prior Art) As this type of support, those shown in FIGS. 8 and 9 have been implemented.

The support shown in FIG. 8 was a hinge previously proposed by the applicant and devised for automatically closing the door (1) by its own weight (Shokai Sho 60-161268).

The hinge can be opened and closed by a pivot shaft (94) fitted to the tubular body (92) (93), with a pair of mounting plates (90) (91) having a tubular body (92) (93) protruding from one end of a flat plate. The end faces of the two cylinders (92) (93) that are in sliding contact with each other are attached to the mounting plates (90) (91).
Helical surfaces (95) (96) are formed so that the tubular body (92) moves outward in the axial direction as is opened.

When the door (1) is pushed in the opening direction, the mounting plate (9
The cylindrical body (92) of (0) rises up on the spiral surface (96) of the mating cylindrical body (93) and rotates. Therefore, the door (1) opens while gradually rising.

When the hand is released from the opened door (1), the weight of the door (1) acts on the upper cylinder (92), and conversely to the above, the upper cylinder (9).
2) knocks down the spiral surface (96) of the lower tubular body (93) and rotates, and the door (1) automatically closes.

The rotation support tool for the door shown in FIG. 9 includes a lower support tool (3) for rotatably supporting the pivotal support side of the lower surface of the door (1) and a pivotal support side of the upper surface of the door (1). The lower support (3) is composed of an upper support (6) that is movably supported, and as shown in FIG. 10, the lower support (3) is rotatably supported by the support (4) and the support (4). The mounting base (5) is mounted and has a door mounting portion (55), and the end faces of the supporting base (4) and the mounting base (5) that are slidably opposed to each other are such that the mounting base (5) is the door (1). ), The mounting base (5) is formed with spiral surfaces (47) (54) so as to move outward in the axial direction.

(Problems to be solved by the invention) Although the hinge of FIG. 8 is mainly used for a pivot support of a door of a toilet, the toilet door is attached to the side edge of the pivot of the door (1) as shown in FIG. In order to hide the gap between the side wall plate (2) and the side wall plate (2), a scale plate (21) is attached to the outside of the wall plate (2).

When the door is pivotally supported by the hinge (9), the hinge cylinder (92)
Since (93) is exposed to the outside, it obstructs the attachment of the scale plate (21), and it is unavoidable to avoid the protruding part of the hinge and divide the scale plate (21) to attach it, resulting in poor workability.
Moreover, there was a problem that the appearance was not good.

The rotation support of the door shown in FIG. 9 has the weight of the door (1) supported by the spiral surface (47) of the support base (4), so that the support base (4) and the mounting base (5) are concentric. The bending moment acts on the shaft (40) that keeps the temperature of the door, and the rotation of the door becomes heavy. Also, the shaft (40)
The top surface of the spiral surface (47) is always rubbed against the inner surface of the shaft hole of the mounting portion (55), which accelerates wear and increases rattling.

Moreover, the height position of the door cannot be adjusted when the door is closed or opened.

In a toilet with multiple toilet booths, the floor is gently sloping to improve the water sweep, so even if you use the same type of support to support the door, the height of the door will vary. It happened and didn't look good.

Further, since the support base (4) is screwed to the lower part of the pillar, when it is applied to the toilet, water is splashed during cleaning,
There was a problem that the screwed part was likely to rot.

The present invention clarifies a door rotation support device that can solve the above problems all at once.

(Means for Solving the Problems) A door rotation support device of the present invention comprises a lower support device (3) for rotatably supporting a pivot side of a lower surface of a door (1) and a pivot support of an upper surface of the door (1). The lower support tool (3) is composed of an upper support tool (6) for rotatably supporting the side up and down, and the lower support tool (3) is fixed to the floor surface and rotated by the support table (4). A mounting base (5) which is mounted so as to be possible and has a door mounting portion (55), and the mounting base (5) is a door at the end faces of the supporting base (4) and the mounting base (5) which are in sliding contact with each other. As the mounting base (5) moves in the axial direction as it rotates in the opening direction of (1), the spiral surface (4
7) In the fixture for the door forming (54), the support base (4) has a screw shaft (42) projecting vertically upward at the center of the base plate (41). ) Is formed by screwing a receiving cylinder (44) into the screw shaft (42), and axially formed clamping grooves (43a) (43a). The receiving cylinder (44) is formed into an inner cylinder (45).
It is formed as a double cylinder consisting of an outer cylinder (46) and an inner cylinder (45).
The screw shaft (42) is screwed onto the screw shaft, the clamp screw (49) is screwed through the both cylinders, the tip of the screw (49) is fitted into the clamp groove (43a), and the outer cylinder ( The upper end surface of 46) has a spiral surface (47) (47) formed symmetrically with respect to the surface including the axis, and the upper end surface of the inner cylinder (45) also has a symmetrical spiral surface (with respect to the surface including the axis). 47a) (47a) are formed, and the tops of the spiral surfaces (47) (47a) of the outer cylinder (46) and the inner cylinder (45) are at the same height.
A cylinder body (51) and a cylinder body (51) which are located at 80 ° symmetry and are slidably fitted in the screw shaft (42) of the support base (4) so as to be slidable in the axial direction. And a door mounting portion (55) provided at the upper end of the (51),
Is formed in a double cylinder including an inner cylinder (52) and an outer cylinder (53), and the lower surface of each cylinder has a spiral surface (47) (47a) of the receiving cylinder (44) of the support base (4). ) Corresponding to the spiral surface (54) (54a) is formed.

(Operation and Effect) When the door (1) is pushed in the opening direction, the door mount (5) of the lower support (3) rolls up on the spiral surface (47) of the mating support (4) and rotates. Therefore, the door (1) opens while gradually rising.

When the hand is released from the open door (1), the weight of the door (1) acts on the mounting base (5), and conversely to the above, the mounting base (5) causes the spiral surface (47) of the support base (4). ), Turn around, and open the door (1)
Automatically closes.

Since the upper end and the lower end on the pivot side of the door (1) are rotatably supported by the lower support tool (3) and the upper support tool (6) arranged in a straight line up and down, like a conventional hinge, There is no protrusion to the outside between the door (1) and the wall plate (2), and the vertical end surface of the door can be arranged so as to be as close to the wall plate (2) as possible without leaving a gap. Between the door (1) and the wall plate (2), it is possible to close it with one scale plate (21), which improves workability and improves the appearance.

Further, since the lower support tool (3) is usually attached to the floor surface of the tiled floor or the mortar floor, the attachment portion does not get wet and rot.

In addition, the support base (4) of the lower support (3) rotates the receiving cylinder (44) screwed to the screw shaft (42) to adjust the height of the receiving cylinder (44), and the door ( Since the height of the closed position of 1) can be adjusted, the heights of the doors (1) (1) of the plurality of toilet booths can be equalized regardless of the water gradient on the floor surface.

Furthermore, the inner cylinder (45) and outer cylinder (46) of the support base (4) are 180 °
The spiral surfaces (54) (54a) symmetrically formed on the inner cylinder (52) and the outer cylinder (53) of the mounting base (5) slide on the symmetrical spiral surfaces (47) (47a). Since they are in contact with each other, the bending shaft does not act on the screw shaft (42) protrudingly provided on the support base (4) and fitted in the inner cylinder (52) of the mounting base (5) with a margin. , The door rotates lightly, and the screw shaft (42) is not worn out.

(Embodiment) Hereinafter, the present invention will be described in detail based on an embodiment of a pivot support for each door of a toilet having a plurality of toilet booths.

FIG. 1 shows a lower support tool (3) for rotatably supporting the lower part of the door and an upper support tool (6) for rotatably supporting the upper part of the door.

The lower support tool (3) is composed of a support base (4) fixed to the floor and a mounting base (5) rotatably supported by the support base (4) and having a door mounting part (55). It

The support base (4) is formed by vertically projecting a screw shaft (42) at the center of a circular base plate (41) and screwing a receiving cylinder (44) of the shaft.

As shown in FIG. 2, a plurality of mounting holes (40) are formed on the base plate (41) outside the screw shaft (42) at equal intervals, and the screw shaft (42) has a 180 ° symmetrical position in the axial direction. Two clamp grooves (43a) (43a) are opened over the entire length of the.

A spiral surface (47) (47) is formed symmetrically on the upper end surface of the outer cylinder (46) in a plane including the shaft center, and in the upper end surface of the inner cylinder (45) is also symmetrical in a plane including the shaft center. A spiral surface (47a) (47a) is formed.

The tops of the spiral surfaces (47) and (47a) of the outer cylinder (46) and the inner cylinder (45) are at the same height and 180 ° symmetrical, and the bottoms of the outer cylinder (46) and the inner cylinder (45) are also respectively. They are at the same height and 180 ° symmetrical.

The mounting base (5) is provided at the upper end of the cylindrical body (51) that is slidably fitted in the screw shaft (42) of the support base (4) so as to be slidable in the axial direction. Door mounting part (5
5) and are included.

The cylinder body (51) is formed as a double cylinder in which an inner cylinder (52) and an outer cylinder (53) are tightly fitted and fixed, and the lower surface of each cylinder has a receiving cylinder for the support base (4). The spiral surfaces (54) (54a) corresponding to the spiral surfaces (47) (47a) of the (44) are formed.

The mounting portion (55) has a pair of L-shaped sandwiching plates (57) and (57) arranged to face a base plate (56) fixed to the upper end of the tubular body (44) so as to be able to approach and separate from each other. 56) A circular holding plate (58) is screwed on the upper part.

The both sandwiching plates (57) (57) are provided with screw insertion holes (59) for screwing the door.

The spacing between the sandwiching plates (57) and (57) is fixed according to the thickness of the door (1), and the spacing between the sandwiching plates (57) and (57) is fixed by tightening the screw (50) of the holding plate (58). To be done.

The upper support tool (6) is composed of a support fitting (7) attached to the wall plate (2) and a receiving fitting (8) attached to the pivot side of the upper end surface of the door (1).

The support metal fitting (7) has an arm plate (72) projecting forward from the upper end of the mounting plate (71) to be screwed to the wall plate (2), and the support shaft downwardly attached to the tip of the arm plate (72). (73) is protruding.

The receiving metal fitting (8) is provided with a through hole (82) into which the support shaft (73) of the supporting metal fitting (7) is fitted in the receiving plate (81) screwed to the door (1), and the hole edge is rubbed. A resin ring (83) for reduction is attached.

The door (1) has a relief hole (11) which is sufficiently larger than the hole (82) at a position corresponding to the through hole (82) of the receiving fitting (8).

The upper support tool (6) is attached to the support fitting (7) and the upper end of the wall plate (2), and the receiving fitting (8) is attached to the door (1).

The end of the lower surface of the door (1) on the pivotal support side is sandwiched by the sandwiching plates (57) (57) of the mounting base of the lower support (3) and fixed by screws.

The support base (4) is fixed to a pivotal position on the floor, and the support shaft (73) of the support fitting (7) is rotated and slid into the through hole (82) of the receiving fitting (8) at the upper end of the door (1). It fits as much as possible, lifts the door (1), and attaches it to the screw shaft (42) of the support base (4) by the mounting base (5).
Fit the cylinder body (51). At this time, the two-dot chain line in FIG. 6 is shown in a state where the spiral surfaces (47) (47a) of the support base (4) and the spiral surfaces (54) (54a) of the mounting base (5) are completely meshed with each other. As described above, the support base (4) is fixed to the floor so that the door (1) is slightly opened from the fully closed state so that the use of the toilet or the empty state can be seen at a glance. This is because

The wall plate (2) is provided with a scale plate (21) that slightly hangs on the pivotal side edge of the door (1) to hide the gap between the door (1) and the wall plate (2).

However, when the door (1) is pushed in the opening direction, the mount (5) on the side of the door (1) causes the spiral surface (47) (47a) of the mating support (4).
Roll up and rotate. Therefore, the door (1) opens while gradually rising.

The upper support tool (6) of the door (1) slides the support shaft (73) of the support fitting (7) attached to the wall plate (2) into the hole (81) of the upper end receiving fitting (8) of the door (1). Since it is movably fitted and supported, there is no problem in raising the door (1) by opening the door (1).

When the hand is released from the open door (1), the weight of the door (1) acts on the mounting base (5), and conversely to the above, the mounting base (5) causes the spiral surface (47) of the support base (4). ) (47a), get off and spin,
The door (1) closes automatically.

As described above, the lower support tool (3) and the upper support tool (6) rotatably support the upper and lower ends of the pivotal side of the door (1). There is no protrusion to the outside between 1) and the wall plate (2), and the gap between the door (1) and the wall plate (2) can be closed with one scale plate (21). ,
Workability is improved.

The support base (4) of the lower support (3) rotates the receiving cylinder (44) screwed to the screw shaft (42) to adjust the height of the receiving cylinder (44), and the door (1). It is possible to adjust the height of the closed position of.

Therefore, as shown in FIG. 5, when a plurality of toilet booths are lined up, the wall plate (2) between the doors (1) and (1) and the door (1)
Is mounted slightly above the floor for convenience of cleaning.

Since the wall board (2) is supported by a pedestal (22) which is fixed to the floor surface and whose height is adjustable, even if a gentle water gradient is formed on the floor surface, The bottom surface height can be made uniform. However, in the conventional hinge supporting the door (1), the height of the door (1) is determined by the mounting position of the hinge, and the lower end of each door (1) is the lower end of the wall plate (2) plate. There was a problem that workability was poor because it took time to determine the mounting height of the hinges so that

In the present invention, the support base (4) of the lower support (3) is configured to change the closing angle of the door (1) by rotating the receiving tube (44) screwed to the screw shaft (42) in 180 ° units. Without changing
The mounting height position can be adjusted, and the above problem can be solved.

Furthermore, according to the present invention, the inner cylinder (45) and the outer cylinder (46) of the support base (4) are formed with 180 ° symmetrical spiral surfaces (47) (47a).
In addition, since the spiral surfaces (54) (54a) symmetrically formed at 180 ° are slidably in contact with the inner cylinder (52) and the outer cylinder (53) of the mounting base (5), they project onto the supporting base (4). For the screw shaft (42) that is installed and fitted in the inner cylinder (52) of the mounting base (5) with a margin,
The bending moment does not work, the door turns lightly, and the screw shaft (4
The loss of 2) does not occur.

The present invention is not limited to the configuration of the above embodiment, and it is needless to say that various modifications can be made within the scope of the claims for utility model registration.
