Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a special tube expressing decorativeness and luxury, which is used to open and close a partition door in an apartment house to a door frame etc. The present invention relates to a hinge having a portion.

(Prior Art) As shown in FIG. 10, a hinge used for mounting a door on a door frame so as to be openable and closable is an upper and lower tubular portion formed by bending one side end into a tubular shape, respectively. Upper and lower blades 33, 34 provided with 31, 32 are rotatably held by inserting a shaft core 35 into the upper and lower cylindrical portions 31, 32. 36 is the upper and lower tubular parts 31, 32
A ring made of metal, synthetic resin, etc. held between, 37 is a cover that covers the upper and lower openings of the upper and lower tubular parts, and 38 is the upper and lower blades 33, 34. A screw hole, 39, is a hinge used to fix the object.

The hinge 39 is used by fixing the upper blade plate 33 to the door and the lower blade plate 34 to the door frame or the like with screws via screw holes 38, respectively.

(Problems to be solved by the invention) Generally, in order to attach a door to a door frame with a hinge 39, the upper blade plate 33 is removed from the shaft core 35, and the upper blade plate 33 is placed at a predetermined position of the door and the lower blade. Place the plate 34 in the specified position of the door frame and screw holes 38, respectively.
After fixing by fixing with screws via, the upper cylinder part 31 of the upper blade plate 33 is fitted to the shaft core 35 held by the lower blade plate 34 by lifting the door.

In this case, since the upper blade plate 33 is pulled away from the lower blade plate 34, the ring 36 fitted to the shaft core 35 may fall off at the attachment work site and be lost, which may interfere with the work. Often.

In addition, the grab bar 37 used to cover the opening of the upper and lower tubular portions 31 and 32 prevents the leg portion 40 from falling off during use of the hinge 39 so that the leg portion 40 is attached to the upper and lower tubular portions 31 and 32. It is press-fitted and fixed to the upper and lower tubular portions 31, 32 by welding or the like as necessary.

However, since the leg portion 40 of the gibbo 37 that is press-fitted into the upper and lower tubular portions 31, 32 is short, it gradually becomes loose over time, and in addition, it is difficult to weld,
Since an imperfect one is also formed, during operation of the hinge 39, the drop 37 of the lower tubular portion 32 may fall off, and along with that, the shaft core 35 may also come off and an accident may occur in which the door cannot be opened and closed.

In addition, the tendency for general preference to seek individuality and luxury has become stronger recently. For example, a room door or a wooden door with a solid feeling, a hinge made of a heavy brass casting that was widely used in Europe in the past, even for the parts used for that door,
For example, a handle. However, such hinges are not mass-produced, and the price is considerably high and difficult to obtain.

(Means for Solving the Problem) The present invention has been made in view of the above-mentioned problems of the related art. -The purpose is to solve the above problems by covering the lower cylinder part and fixing the ring that surrounds the inner ring with a ring cover in a non-separable manner with a shaft rod tightened to the lower cylinder part. There is.

The present invention is a gibbo that has legs that are press-fitted inside the upper and lower tubular portions, which are formed at one end of the upper and lower blades, respectively.
A tube case provided with an opening of a required length in the height direction with a width the same as the thickness of both blades is attached so as to enclose the legs and integrated by an appropriate means. In addition, a hollow case that is press-fitted to both of the cylindrical portions through the opening, and an inner ring having a locking mechanism for the shaft surrounded by a ring cover, and a ring sandwiched between the both cylindrical portions, A special pipe portion fitted with the both tubular portions and the ring, the lower portion of which is fixed to the lower tubular portion, and the shaft rod which rotatably holds the both vane plates. It is a hinge provided.

(Operation) Since the hinge locks the ring by the shaft rod that is securely fixed to the lower cylinder part, even if the upper blade is pulled out from the shaft rod, the ring will be lost as before. Never occurs.

In addition, the hinge has a
It is press-fitted into the inside of the lower cylinder, and a double locking mechanism is used to cover the outside of the upper and lower cylinders with a pipe case that is integrated into the groove and is fitted with a double lock mechanism.
