例えば、実開昭６１−２０８８０号公報参照）。As a conventional example 1 of this type of gravity hinge, a rotary cylinder that rotates together with the door is rotatably fitted around the outer periphery of a guide shaft provided on a fixed lower support, and guided on the lower support. A pair of upper and lower elliptical inclined surfaces obtained by cutting the cylinder diagonally with respect to the axis are formed on the fixed cylinder provided on the outer periphery of the shaft and the rotating cylinder, and the door's own weight is used to There is a device in which a pair of upper and lower elliptical inclined surfaces are made to slide against each other, and a rotating cylinder is rotated around a guide shaft to rotate the door in the opening or closing direction (for example, Jitsukai Showa 58-+101
(See Japanese Utility Model Publication No. 68 and Japanese Utility Model Application No. 140066/1983). In addition, as a conventional example 2 of this type of gravity hinge, a guide shaft is attached between a pair of upper and lower protrusions of a fixed member formed in a hollow shape to guide a substantially convex rotating member that rotates together with the door. A pair of upper and lower cam bodies are rotatably attached to the outer periphery of the shaft and fitted around the outer periphery of the guide shaft between the lower part of the rotating member and the upper part of the lower protrusion of the fixed member. The cam body is fixed to the side protrusion, and the upper and lower pair of cam bodies are made to slide against each other using the weight of the door.
Some devices rotate a rotating member around a guide shaft to force the door to rotate in the opening or closing direction (
For example, see Japanese Utility Model Application No. 61-20880).

いる。However, in conventional gravity hinges, when the rotating cylinder is rotated together with the door, the upper sloping surface of the ellipse slides on the lower sloping surface around the guide axis in point contact. It turns out. The sliding movement caused by this point contact prematurely wears out the pair of upper and lower elliptical inclined surfaces. In addition, the point where the lower inclined surface of the ellipse supports the upper inclined surface is offset from the center of rotation of the hinge (axis of the guide shaft).
Since the rotating cylinder is only a dot, the rotating cylinder cannot rotate in a well-balanced manner around the center of rotation of the hinge, and the rotating cylinder rotates at an angle to the guide shaft, causing premature uneven wear between the rotating cylinder and the guide shaft. There was a problem in that the door was easy to move and rattled easily. In addition, the gravity hinge of Conventional Example 2 incorporates a guide shaft and a pair of upper and lower cam bodies between the fixed member and the rotating member, and has a large number of parts (and a complicated structure. In particular, the fixed member There was a problem in that the assembly work of attaching a guide shaft between a pair of upper and lower protrusions and attaching a rotating member and a pair of upper and lower cam bodies to the outer periphery of the guide shaft was troublesome and time-consuming. Both gravity hinges 1 and 2 have a problem in that the height of the door cannot be easily adjusted because the hinge itself does not have a height adjustment function.The present invention has less early wear and uneven wear. Moreover, it is an object of the present invention to provide a gravity hinge that is simple in structure and assembly, and in which the height of the door can be easily adjusted.

ることを防止できる。According to the gravity hinge configured as described above, the pair of upper and lower spiral cylindrical surfaces are always in surface contact, and the rotating cylinder is moved inside the supporting cylinder by the mutual sliding action of the pair of upper and lower spiral cylindrical surfaces using the weight of the door. The door can be rotated in a well-balanced manner to automatically rotate the door in the opening or closing direction. In addition, the height of the support cylinder relative to the fixed cylinder is adjusted by the screw feeding action by rotationally adjusting the support cylinder, so that the height of the door can be easily adjusted together with the rotating cylinder supported by the support cylinder. After adjusting the height,
By fixing the support cylinder with a locking nut, it is possible to prevent the support cylinder from being rotated due to the rotational friction of the rotating cylinder that is rotated together with the door.

基づいて、各種の有効な変更が可能である。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a gravity hinge in which the present invention is applied to a door of a toilet booth will be described below with reference to the drawings. First, an overview of the toilet booth will be explained with reference to FIG. The figure shows a triple toilet booth I, and each toilet booth unit la is composed of a door 2, a front panel 3, and side and partition panels 4. The upper edge of the front panel 3 is fixed to the lower surface of the horizontally installed head joint 5, and the lower edges of the front panel 3, the side surfaces, and the partition panel 4 are fixed to the lower surface of a plurality of panel support devices 6 installed on the floor. installed on. Note that the side surfaces and the back side of the partition panel 4 are fixed to a wall or the like. The door 2 has its lower edge rotatably attached to a gravity hinge 7 installed on the floor surface, and its upper edge rotatably attached to a hinge 8 interposed between the door 2 and the lower surface of the head joint 5. The door 2 is moved in the opening direction (
It is configured to be automatically rotated in the direction of arrow a) or in the closing direction (direction of arrow A). Note that 9 indicates a door latch that maintains the closed state of the door 2. Next, an outline of the mounting structure of the door 2 will be explained with reference to FIGS. 2 and 3. First, the lower gravity hinge 7 includes a rotary cylinder 11 that rotates together with the door 2, a support cylinder 12 that supports the rotary cylinder 11 from below, and a support cylinder 12 that is fixed on a floor surface 13 and arranged at the bottom of the support cylinder 12. It consists of a fixed cylinder 14 and a locking nut 15. The support cylinder 12 is attached to the outer periphery of the fixed cylinder I4 so that its height can be adjusted, and the rotary cylinder 11 is rotatably fitted into the support cylinder 12. Note that details of this gravity hinge 7 will be described later. Next, the upper hinge 8 includes a rotating component 17 that is integrally provided with a rotating shaft 17a, and a bearing component 18 that is integrally provided with a bearing 18a for the rotating shaft 17a. The rotating component 17 is fixed to the upper end surface of the door 2 by a plurality of screws 19, the bearing component 18 is fixed to the lower surface of the head joint 5 and between the top and bottom surfaces of the head joint 5 and the front panel 3 by a plurality of screws 20, The rotating shaft 17a is rotatably fitted into the bearing 18a from below. Note that the bearing 18a of the bearing component 18 is fitted into a groove 21 provided in the head joint 5. The rotation centers P of the lower gravity hinge 7 and the upper hinge 8 are the same. Additionally, the components of the pair of upper and lower hinges 7.8 are as follows:
Engineering plastics (a general term for hard plastics that have almost the same hardness as metals; typical examples include polyacecool, polycarbonate, polyamide,
Examples include modified polyphenylene ether, reinforced polyethylene terephthalate, and polybutylene phthalate. ), but it is best to mold it with polyacecool, which has excellent self-lubricating properties, a low coefficient of friction, and high wear resistance. Further, the head joint 5 has a structure in which the outer surface of an aluminum profile is coated with resin. The door 2 is configured to be rotated around a rotation center P of a lower gravity hinge 7 and an upper hinge 8 to open and close in the directions of arrows a and b. Next, according to FIGS. 4 to 6, the gravity hinge 7
Explain the details. First, the rotating cylinder 11 has a door holder 23 whose cross section is approximately L-shaped.
The door holder 23 is integrally formed on the lower surface of the door 2.
It is fixed to the lower edge of the holder with a plurality of screws 24. An upper spiral cylindrical surface 2 is attached to the lower end surface of the rotating cylinder 11.
5 is formed. An annular step 26 is integrally molded in the interior 12a of the upper half of the support cylinder 12 into which the rotating cylinder 11 is fitted, and a lower spiral cylindrical surface 27 is formed on the upper end surface of the step 26. Furthermore, a female thread 28 is formed on the inner periphery of the lower half of the support cylinder 12 . Note that the fixed cylinder is screwed into the lower half of the support cylinder 12! There is a male thread 30 on the outer periphery of 4.
is formed and the locking nut 15 is attached to the male thread 30 here.
are screwed together. Further, a flange 31 is integrally molded at the lower end of the fixed cylinder 14. This gravity hinge 7 has a central part of a flange 31 of a fixed cylinder 14 fixed to a concrete anchor 32 embedded in a concrete floor 13a forming a floor surface I3 with a screw 33, and a support cylinder 1 attached to a male thread 30 of the fixed cylinder 14.
2 female screws 28 are screwed together, and the rotating cylinder 11 is connected to the supporting cylinder 1.
2, and the upper and lower spiral cylindrical surfaces 25, 27 are in surface contact with each other from above and below. According to the gravity hinge 7 configured as described above,
Due to the weight of the door 2, a pair of upper and lower spiral cylindrical surfaces 2
5.27 is in constant surface contact. When a person manually rotates the door 2 in the closing direction (arrow direction) or opening direction (arrow a direction), the rotating cylinder 11 is moved to the support cylinder 12 by the sliding action of the pair of upper and lower spiral cylindrical surfaces 25 and 27. It slides upward while rotating together with the door 2 inside the door 12a. Next, when you release your hand from the door 2 that has been rotated in the closing or opening direction, the rotating cylinder 11 moves against the support cylinder 12 by the mutual sliding action of the pair of upper and lower spanral cylindrical surfaces 25 and 27 using the weight of the door 2. Inside 12a, the door 2 slides down while rotating together with the door 2, and the door 2 is automatically rotated in the opening direction (arrow λ direction) or closing direction (arrow arrow direction) and returns to its original position. At this time, since the pair of upper and lower spiral cylindrical surfaces 25.27 always slide while being in surface contact with each other, early wear of the pair of upper and lower spiral cylindrical surfaces 25.27 does not occur. Furthermore, the rotating cylinder II can rotate in a well-balanced manner inside the support cylinder 12 due to the sliding action caused by the surface contact between the upper and lower spiral cylindrical surfaces 25 and 27, so that the rotating cylinder 1! There is also little uneven wear between the support cylinder 12 and the support cylinder 12. Therefore, it has excellent abrasion resistance, and the door 2 can be smoothly opened and closed without rattling. In particular, if the various parts constituting the gravity hinge 7 are made of engineering plastic, the friction coefficient will be lower than that of metal parts, so the door 2 will open and close smoothly, and will also be highly wear resistant. Improves durability. Moreover, according to this gravity hinge 7, the support cylinder 12
When the rotation is adjusted, the fixed cylinder is fixed by the screw feeding action of the male screw 30 and female screw 28! Support cylinder 1 for 4
You can adjust the height of 2. By adjusting the height of the support cylinder 12, the height of the door 2 supported by the door receiver 23 of the rotating cylinder 11 can be easily adjusted. After adjusting the height, the lower end surface 12b of the support cylinder 12 is crimped onto the locking nut 15 to fix the support cylinder 12, and the rotational friction of the rotating cylinder 11, which is rotated together with the door 2, provides support. The cylinder 12 can be prevented from being rotated. Therefore, every time the door 2 is opened or closed, the support cylinder 12 will not rotate unexpectedly and the height of the door 2 will change. Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various effective changes can be made based on the technical idea of the present invention.

も発生しない。Since the present invention is configured as described above, it produces the effects described below. In the gravity hinge of claim 1, the rotary cylinder that rotates together with the door slides with the support cylinder that supports it from below while being constantly in surface contact with the pair of upper and lower spiral cylinder surfaces. , the premature wear that tends to occur with conventional point contacts does not occur. Moreover, since the rotating cylinder can rotate in a well-balanced manner within the supporting cylinder due to the sliding action caused by the surface contact between the upper and lower spiral cylindrical surfaces, there is little uneven wear between the rotating cylinder and the supporting cylinder. Therefore, it has excellent abrasion resistance, and the door is less likely to rattle. On the other hand, since the support cylinder constitutes a guide member for the rotating cylinder and a kite shaft for the rotating cylinder is not required, the number of parts is small and the structure is simple. In particular, the assembly of the gravity hinge can be completed by simply fitting the rotary cylinder into the support cylinder from above, making the assembly work very simple. In the gravity hinge of claim 2, the height of the door can be easily adjusted by simply adjusting the rotation of the support cylinder from the outside. Furthermore, by fixing the support cylinder with a locking nut after adjusting the height, there will be no inconvenience such as the support cylinder unexpectedly rotating and changing the height of the door each time the door is opened or closed. .
