Description

[Detailed Description of the Invention] This invention relates to a hinge particularly suitable for heavy doors.

Conventionally, when suspending a door, after aligning the lower end of the shaft cylinder of the upper part with the upper end of the shaft of the lower part which is arranged at least in two stages above and below the door frame and the vertical stile of the door, While lowering the door, the shaft cylinder was fitted onto the support shaft.

However, since the protruding length of each support shaft is the same, the support shafts of the upper and lower hinges must be aligned with the shaft cylinder at the same time, and heavy items such as doors cannot be lifted by one person. There were other drawbacks.

The purpose of this invention is to provide a hinge that can be suspended without having to align each support shaft and shaft cylinder at the same time.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the diagram, the hinge A has a pair of upper and lower mounting pieces 1 and 2.
and shaft cylinders 3 and 4 provided on the inner edges of both pieces 1 and 2,
It consists of a shaft member 5 whose upper part protrudes so as to fit into the shaft cylinder 3 of the upper part 1 and whose lower part is fitted and supported by the shaft cylinder 4 of the lower part 2.

The shaft member 5 is provided with a hole 6 extending downward from the upper end surface.

In addition, a padding material 7 is fixed to the upper part of the shaft tube 3 of the upper part 1, and the padding material 7 has three stepped recessed holes 8 whose diameter gradually decreases upward from the lower end surface. is provided.

Further, heads 9.9', 9'' are provided which fit into each step from the lower stage to the upper stage of the stepped recessed hole 8, and the lower surface of each head 9.9', 9'' is provided with a hole. A protruding shaft 10 that fits into the shaft 6 is provided.

In addition, the shapes of the above-mentioned heads 9.9', 9'' are as shown in the figure: one that fits only into the lower stage of the stepped recess 8, one that fits into the lower stage and the next stage, and one that fits from the lower stage. Although it is shaped like something that fits into the upper part, it may be a head for each stage.

Further, although the illustrated case shows a three-stage stepped concave hole 8, a two-stage one may be used in some cases.

Furthermore, although a pipe is used for the shaft material 5, there is a hole 6 at the upper end of the shaft.
may be provided.

In the figure, 11 is a caulking shaft for fixing the shaft material 5 to the shaft tube 4, and 12 is a caulking shaft for fixing the stuffing material 7 to the shaft tube 3.

The hinge according to this invention differs from the above-mentioned structure, and the following describes how to use the hinge.As shown in FIG. The number pieces 2 are screwed to the vertical stile C, respectively, and three stages of hinges A are arranged between the upper and lower ends of the vertical stile.

Next, a protruding shaft 10 having a head 9'' is connected to the hole 6 of the upper shaft member 5 in contact with the upper stage of the stepped recessed hole 8, and a protruding shaft 10 having a head 9″ is connected to the hole 6 of the middle stage shaft member 5 in contact with the middle stage of the stepped recessed hole 8. A protruding shaft 10 having a head 9',
The head 9 contacts the lower stage of the stepped recessed hole 8 with the hole 6 of the lower shaft member 5
The protruding shafts 10 having the following shapes are respectively inserted.

That is, the protruding length of each head becomes shorter from the upper stage to the lower stage.

Afterwards, lift door B and remove shaft cylinder 3 of upper hinge A.
After aligning the lower end of the door with the upper head 9'', the lower end of the barrel 3 is fitted into the head 9'' by lowering the door slightly.

Then, by aligning the shaft tube 3 of the middle hinge A with the middle head 9' and lowering the door B slightly, the head of the lower hinge A is repeatedly fitted into the head 9'. 9 and the shaft tube 3, and then, without lowering the lower part A, fit the shaft tube 3 to each shaft member 5.

At this time, the upper end of the head 9'' is in the upper step of the stepped recess 8 of the upper hinge A, the upper end of the head 9' is in the middle of the stepped recess 8 of the middle hinge A, and the upper end of the head 9'' is in the stepped recess of the lower hinge A. The upper ends of the heads 9 abut the lower stages of the holes 8, respectively.

As described above, according to the hinge according to this invention, a filling material is provided in the upper part of the shaft cylinder of the upper flap, and a stepped concave hole whose diameter gradually decreases upward from the lower end surface of the filling material. and also,
A hole is provided at the upper end of the support shaft, and a protruding shaft having a head with a required protrusion length is inserted into this hole, so that a protruding shaft with a long protruding head can be inserted into the upper hinge and a protruding shaft with a long protruding head can be inserted into the lower hinge. By using a head with a short protruding length, the shaft member and the shaft cylinder can be fitted sequentially from the upper side to the lower side.

Therefore, it is not necessary to match each shaft cylinder and shaft member at once as in the conventional case, and even a heavy door can be hung by one person.
