Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement of a hinge that allows fine adjustment of the vertical position of a door. A door that is opened and closed relative to a door frame must maintain proper clearance relative to the door frame when closed. The hinge of this invention is of a type that allows fine adjustment of its vertical position when the door sags during installation or use.

[Conventional technology]

Conventional hinges of this type include, for example, the Jitsukaisho
Examples include those shown in Japanese Patent No. 62-16671. The hinge has a shaft pin inserted into the bearings of a pair of left and right blades, a collar member that can be tapped is fixed inside at least one opening of each bearing, and a screw member is inserted into the hole of the collar member. It is configured to be adjusted up and down by tapping. However, with this hinge, the load of the door is directly supported at the tip of the screw member through the upper slat to which the door is fixed and the shaft pin whose collar receives the lower end of the bearing. In other words, a large load is always applied to the tip of the screw member from the shaft pin, and as a result, the shaft pin, which rotates together with the upper blade plate as the door opens and closes, also applies rotational force to the screw member. A door whose vertical position is properly adjusted by a screw member is
Repeated rotation of the screw causes misalignment in the vertical position.

[The problem that the idea aims to solve]

The object of this invention is to provide a hinge that solves the above-mentioned problems and prevents the vertical position of the door from being misaligned.

[Means for Solving the Problems] The hinge of this invention is a hinge in which a shaft core is vertically movably inserted into a cylindrical bearing portion of a pair of vanes, and the hinge is configured such that at least one of the bearing portions and the shaft A vertically movable auxiliary cylinder is interposed between the core and one end of the cylinder faces the inner end of the other bearing in the longitudinal direction, and the other end can slide into one of the bearings. The bearing is supported by a bridge piece inserted into the shaft, and the bridge piece is held so as to be displaceable at the tip side of a screw operating member movably attached to one of the bearings in the length direction. It is. A second invention is the first invention in which a rotation preventing means for preventing rotational displacement of the bridge piece is provided between the bridge piece and one of the bearings.

This invention will be explained below based on embodiments shown in the drawings. Each member constituting the hinge of this invention is made of brass, iron, other metal materials, synthetic resin materials, or the like.

In the first embodiment shown in FIGS. 1 to 4,
1 and 2 are a pair of upper and lower blade plates, 1a and 2a are cylindrical bearings of the blade plates 1 and 2, and 1b and 2b are bearings that are integrally formed by curving one side of the blade plates 1 and 2. A narrow gap in the length direction of parts 1a and 2a, 1c and 2
Reference numeral c indicates a screw hole for attaching the blade plates 1 and 2 with screws 15, and reference numeral 3 indicates a shaft core inserted into the bearing portions 1a and 2a so as to be movable in the vertical direction.

A vertically movable auxiliary cylinder 5 is interposed between at least one (lower) bearing part 2a and the shaft core 3. 5a is one end 5 in the length direction of the auxiliary cylinder 5
b is an integral flange portion provided as necessary. Flange portion 5a on one end side 5b of auxiliary cylinder 5
is made to face the inner end side 1d in the length direction of the other (upper) bearing part 1a, and is inserted into the inner part of the upper bearing part 1a through a cylindrical decorative cover 6 integrally provided with a sliding part 6a. Support the end side 1d. makeup cover 6
Since the sliding portion 6a serves as a seat plate during rotation, the entire decorative cover 6 is preferably made of a synthetic resin material with a low coefficient of friction. Reference numeral 6b is an insertion hole through which the shaft core 3 passes, and reference numeral 6c is an escape groove into which one of the blade plates 2 is fitted so as to be displaceable. However, the above-mentioned decorative cover 6 is not an essential member because the function of the hinge can be achieved even without it.

The other end side 5c of the auxiliary cylinder 5 is supported by a piece 7 that is slidably inserted into one of the bearings 2a along its length. is held movably at the tip end 8a of a screw operating member 8 attached to the outer end 2d in the longitudinal direction of one of the bearings 2a.

In this first embodiment, the threaded portion on the distal end side 8a of the screw operating member 8 is screwed into the piece 7, and the proximal end side 8b is fixed separately or integrally to the outer end side 2d of the bearing portion 2a. A cylindrical support piece 9 provided at
It is rotatably attached to the. Reference numeral 8c is a locking portion to which a tool such as a driver for rotating the screw operating member 8 is locked.

Further, it is desirable that the aforementioned piece 7 is provided with a rotation preventing means 10 for preventing its rotational displacement. The anti-rotation means 10 is provided between the piece 7 and one bearing part 2a, and in the first embodiment, a protrusion 7a integrally provided on the piece 7 is provided on one bearing part 2a. It is constructed by fitting into the narrow gap between 2a and 2b. The piece 7 that supports the auxiliary tube 5 should be made of a synthetic resin material with a low coefficient of friction or have a sufficiently smooth surface so that no rotational force is applied from the auxiliary tube 5. is desired.

Although not shown, other anti-rotation means include:
One example is one in which a protrusion is partially provided in the longitudinal direction of the inner surface of the bearing portion 2a, and a groove is provided in the piece 7 to slidably fit into the protrusion.

In this invention, the shaft core 3 is inserted so as to be movable in the vertical direction, and is formed to an appropriate length so that the load of the other (upper) slat 1 and the door 13 attached to it is not applied at all. be.

Reference numeral 12 denotes an auxiliary cylinder which is rotatably inserted with the upper part of the shaft core 3 being slidable and rotatably inserted into the bearing portion 1a of the other vane plate 1, either slidably or fixedly. Reference numeral 12a denotes a flange portion integrally provided on the inner end side in the longitudinal direction of the sub-tube 12, which abuts against the sliding portion 6a of the decorative cover 6 described above. Incidentally, the entire sub-cylinder 12 can also be formed integrally with the bearing portion 1a of the vane plate 1.

[Effect]

Next, the operation of the first embodiment of this invention will be explained. In FIG. 2, the other (upper) wing plate 1 attached to the door 13 is raised by a distance l from the lowest position with respect to the other (lower) wing plate 2 attached to the door frame or other fixed member 14. in a state. By rotating the screw operating member 8 to the right or left with a tool such as a door driver, the piece 7
When the auxiliary cylinder 5 supported by the piece 7 is moved upward or downward, the auxiliary cylinder 5 is also moved upward or downward. Therefore, a decorative cover 6 is provided on one end side 5b of the auxiliary cylinder 5.
The bearing portion 1a of the other vane plate 1, which is opposed and supported via the sliding portion 6a of
is the one whose displacement is adjusted up and down. The load of the door 13 and the upper wing plate 1 is supported by the bridge piece 7 via the auxiliary tube 5, and is not applied directly to the screw operating member 8, so even if the door 13 is repeatedly opened and closed, the screw cannot be operated. The member 8 does not rotate to the right or left, and the door 13 maintains an appropriate vertical position for a long period of time. Further, the holding of the proper position is particularly reliable in the case where the piece 7 is provided with the detent means 10, but even in the case where the piece 7 is not provided with the detent means 10, the upper Since the bearing portion 1a of the vane plate 1 and the auxiliary cylinder 5 and the auxiliary cylinder 5 and the bridge piece 7 are not directly connected, the rotational force from the vane plate 1 is hardly transmitted, and the door The vertical position of 13 will be maintained appropriately.

〔Example〕

FIG. 5 shows a second embodiment of this invention. In this embodiment, the screw operating member 8 is screwed onto a support piece 9 fixed to one of the bearings 2a, so that the tip end 8a of the screw operating member 8 pushes up the piece 7. The other configurations are the same as those in the first embodiment, and the second embodiment also exhibits effects similar to those described above.

[Effect of idea]

The door attached with the hinge of this invention described above will hardly lose its proper vertical position relative to the door frame during repeated opening and closing operations, and the frequency of readjustment of the hinge will be extremely reduced. It is intended to have the effect of
