The lower regulating member 6 is internally provided, and the shaft body 4 is configured to protrude from one side of the tubular portion 3a.

As shown in FIG. 2, the opening 90 provided in the partition wall 9 that partitions the living room space has an upper frame 80 disposed on the ceiling side and a pair of vertical frames 81 disposed on the left and right of the upper frame 80. , 81 are assembled.
The door frame 8 in the illustrated example shows an example in which the lower frame disposed on the floor side is not provided, but is not limited thereto, and may be provided with a lower frame.
A plurality of hinges 1 are provided on either one of the pair of vertical frames 81 so as to be separated from each other in the vertical direction. As shown in the figure, the hinge 1 includes a door-side hinge 1a provided on the door 7 side, It is comprised with the door frame side hinge 1b provided in the door frame 8. As shown in FIG.

Hereinafter, as shown in FIGS. 1A to 1D, the door-side hinge 1a and the door-frame hinge 1b are configured such that the tubular portion 3a of the door-side hinge 1a is replaced with the tubular portion 3b of the door-frame hinge 1b. A description will be given based on a configuration in which a shaft body 4 that is provided on the upper side and is movable up and down is installed in a cylindrical portion 3a of the door-side hinge 1a provided on the upper side.
The door-side hinge 1a and the door-frame-side hinge 1b include rectangular flat plate-like blade portions 2a, 2b and cylindrical portions 3a, 3b made of a hollow cylindrical body having a bottom, and the blade portions 2a, 2b and the tubular shape. The portions 3a and 3b are integrally formed, and may be integrally formed, or may be formed separately and integrated with each other.
A plurality of insertion holes 20 a are formed in the blade portion 2 a of the door-side hinge 1 a, and a fixing tool (not shown) is inserted through the insertion hole 20 a to firmly fix the blade portion 2 a to the end surface of the door 7. A plurality of insertion holes 20b are also formed in the blade portion 2b of the door frame side hinge 1b, and a fixing tool (not shown) is inserted into the insertion hole 20b to firmly fix the blade portion 2b to the vertical frame 81. .
Here, the number and arrangement of the insertion holes 20a, 20b are not limited to the illustrated example, and the blade portion 2a of the door side hinge 1a and the blade portion 2b of the door frame side hinge 1b are stably provided on the door 7. What is necessary is just to be comprised so that it may adhere to an end surface or the vertical frame 81. FIG.

The door side hinge 1a will be described with reference to FIGS. 3 (a) to 3 (c).
As described above, the door-side hinge 1a includes the blade portion 2a and the cylindrical portion 3a. The cylindrical portion 3a is provided with the bottomed surface 30a facing upward, and the upper regulating member is provided in the cylindrical portion 3a. 5 and a lower regulating member 6 are provided.
The upper restricting member 5 and the lower restricting member 6 are formed in a cylindrical shape so as to be installed along the inner wall of the tubular portion 3 a, and protrude downward from the length of the shaft body 4 and the shaft body 4. They are separated according to the amount.
That is, the lower regulating member 6 is formed so that the lower end portion 4b of the shaft body 4 slightly protrudes from below the cylindrical portion 3a in a state where the shaft body 4 is held at the upper position, and the upper regulating member 5 is When the shaft body 4 held in the upper position is further lifted, the positional relationship is set so that the shaft body 4 comes into contact with the upper end portion 40a of the locking projection 40, and the cylindrical body 3a is internally mounted. desirable.
Further, the upper regulating member 5 includes the bottom surface 30a of the tubular portion 3a and the shaft body so that the upper end portion 4a of the shaft body 4 does not contact the bottomed surface 30a of the tubular portion 3a when the shaft body 4 is lifted upward. It is preferable that a gap is set between the upper end portion 4a of 4 and the cylinder portion 3 is internally provided. In this case, even when the shaft body 4 is lifted up most, the bottomed surface 30a of the cylindrical portion 3a and the upper end portion 4a of the shaft body 4 are not in contact with each other, thereby reducing the occurrence or damage of contact sound. be able to.

The shaft body 4 is formed in a columnar shape, and preferably a tapered portion 41 having a gradually tapered shape may be formed at the lower end portion 4b thereof. Thus, by making the lower end part 4b into the taper 41, for example, the cylindrical part 3b end part of the door frame side hinge 1b is slid laterally from the side surface side of the shaft body 4 to the lower end part 4b of the shaft body 4. Sometimes (see FIG. 6 (a)), the tapered portion 41 smoothly abuts against the end of the cylindrical portion 3b, so that it can be easily affected.
The upper end portion 40a of the locking projection 40 is formed to be inclined obliquely upward, the lower end portion 40b of the locking projection 40 is formed to be inclined obliquely downward, and the engagement projection 40 is trapezoidal. It is preferable that portions corresponding to the upper side and the lower side of the protrusion 40 are provided so as to be parallel to the axial direction of the shaft body 4.
In the drawing, a portion corresponding to the upper side of the trapezoidal locking protrusion 40 is shown as an upper side portion 40c, and a portion corresponding to the lower side is shown as a lower side portion 40d.

Here, the shaft body 4 is not limited to the one that moves downward due to its own weight, but includes a biasing means 10 (see FIG. 3) that is biased in a direction protruding from the cylindrical portion 3a, and by this biasing force, You may make it the lower end part 40b of the latching protrusion 40 contact the lower side regulation member 6. FIG. The urging means 10 is not particularly limited as long as it urges the shaft body 4 in a direction protruding from the cylindrical portion 3a. For example, the urging means 10 contracts and releases the pressing force. Then, it is possible to employ an elastic body such as a spring material or a sponge material that recovers and returns to its original state.
According to this, even if the installation direction of the hinge 1 is, for example, a horizontal direction or a direction opposite to the illustrated example (a pattern in which the shaft body 4 protrudes from the bottom to the top), the shaft body 4 is caused to appear and disappear from the cylindrical portion 3a. Can do. Further, when the urging means 10 is provided, the reaction force acting in the protruding direction of the urging means 10 can be felt when the shaft body 4 is lifted upward, and the click feeling can be improved.

The upper restricting member 5 includes a rotation guide mechanism 50 in which irregularities are continuous in the circumferential direction so that the upper end portion 40a of the locking projection 40 of the shaft body 4 contacts and rotates the shaft body 4 in one direction. .
The configuration of the rotation guide mechanism 50 is not limited to the illustrated example, but when the shaft body 4 is lifted upward, the rotation guide mechanism 50 is tilted upward so that it slides in a state in which the upper end portion 40a of the locking projection 40 is in contact. The inclined guide part 50a formed by cutting and the movement of the shaft body 4 that has been guided by the inclined guide part 50a and rotationally moved to a predetermined position are stopped, and the shaft body 4 is caused by its own weight or the urging force of the urging means 10. It is good also as what is provided with the stopper part 50b guided so that it may move below.

The lower regulating member 6 is engaged with the lower end portion 40b of the locking projection 40 of the shaft body 4 to rotate and move the shaft body 4 in one direction and to lock and hold the shaft body 4 at different positions. A stop guide mechanism 60 is provided.
The configuration of the locking guide mechanism 60 is not limited to the illustrated example, but the shaft body 4 that rotates and moves to the position of the stopper 50b and moves downward by its own weight or the urging force of the urging means 10 is the first engagement. The first inclined guide portion 60a that is cut obliquely downward so as to be guided to the stop groove 60b and the lower end portion 40b of the locking protrusion 40 of the shaft body 4 that is guided and moved by the first inclined guide portion 60a are locked. The first locking groove 60b, the second inclined guide portion 60c cut obliquely downward so as to guide the shaft body 4 lifted upward to the second locking groove 60d, and the second inclined guide portion 60c. A second locking groove 60d that locks the lower end portion 40b of the locking projection 40 of the shaft body 4 that has been guided and moved may be provided.
In the example shown in the figure, the first groove is to be locked so that the lower end portion 4b of the shaft body 4 protrudes from the lower portion of the cylindrical portion 3 by about half a little (see FIGS. 1B and 5C). The case where the groove | channel which is set as the locking groove 60b and is locked so that the lower end part 4b of the shaft body 4 protrudes most from the lower part of the cylindrical part 3 is shown as the 2nd locking groove 60d. In this case, the second locking groove 60d is cut deeper than the first locking groove 60b.

With reference to FIG. 3 and FIG. 4, an example of the projecting structure of the shaft body 4 provided on the hinge 1 will be described in more detail. FIG. 4 schematically shows the upper restriction member 5 and the lower restriction member 6 in a developed view for explaining the movement of the shaft body 4 of the door-side hinge 1a.
The inclined guide portion 50a with which the upper end portion 40a of the locking projection 40 comes into contact is formed so that the inclination angle obliquely upward corresponds to the shape of the upper end portion 40a of the locking projection 40. Therefore, when the locking projection 40 (shaft body 4) is lifted upward, the upper end portion 40a can be slid in a state of being in contact with the inclined guide portion 50a. Moreover, since the inclination angle of the inclination guide part 50a and the upper end part 40a is formed substantially the same as described above, the shaft body 4 can be regulated so as not to reversely rotate.
On the other hand, the 1st inclination guide part 60a which the lower end part 40b of the latching protrusion 40 contacts is formed inclining below toward the 1st latching groove 60b, curving in circular arc shape. Further, the second inclined guide portion 60c with which the lower end portion 40b of the locking projection 40 comes into contact is formed so that the inclination angle thereof obliquely downward corresponds to the shape of the lower end portion 40b of the locking projection 40. Therefore, when the locking protrusion 40 (shaft body 4) moves downward by its own weight or the urging force of the urging means 10, the lower end portion 40b is in contact with the first inclined guide portion 60a or the second inclined guide 60c. You can make it slide.
Note that the shape of the first inclined guide portion 60a is not a curved shape, and may simply be an inclined shape. Here, in order to smoothly move the locking projection 40 into the first locking groove 60b at a short distance, the curved shape is adopted.

The stopper portion 50b temporarily stops the shaft body 4 that has been rotationally moved along the inclined guide portion 50a, and when the stopper portion 50b moves downward due to the weight of the shaft body 4 or the urging force of the urging means 10, the stopper portion 50b It is formed by setting a position where the locking projection 40 can be guided to be locked in the formed first locking groove 60b or second locking groove 60d. The stopper portion 50 b is formed in parallel with the lower side portion 40 d of the locking projection 40 formed in parallel with the axial direction of the shaft body 4. As a result, the lower side portion 40d of the locking projection 40 is guided downward along the stopper portion 50b.
3 and 4, an extension line of the formation position of the stopper portion 50b is shown by a two-dot chain line 61 so that the relationship between the formation positions of the stopper portion 50b and the locking guide portion 60 can be understood.
In this way, the two-dot chain line 61 is set in the vicinity of the first locking groove 60b and the center position of the second locking groove 60d, whereby the shaft body 4 is locked by the locking grooves 60b and 60d to be locked. The protrusion amount can be changed so that the cylindrical portion 3 can freely appear and disappear.

Next, with reference to FIGS. 1 and 4 to 6, the projecting and retracting operation of the shaft body 4 provided on the hinge 1 will be described together with the procedure for hanging the door 7. In addition, the following description is an example of the hanging procedure of the door 7, Comprising: It does not limit to this.
Two hinges 1 are provided separately above and below the door frame 8, and the door side hinge 1a is attached to the door 7 and the door frame side hinge 1b is attached to the door frame 8 (see FIG. 2).
FIGS. 1A and 5A show a state in which the cylindrical body 3a protrudes most from the shaft body 4. At this time, the locking projection 40 is engaged with the second locking groove 60d that is deeply cut. It is stopped (see the locking projection 40 shown by the solid line in FIG. 4).

From this state, first, the shaft body 4 of the door-side hinge 1a attached to the upper side of the door 7 is pushed up with fingers.
As shown in FIG. 5 (b), when the shaft body 4 is pushed up in this way, the upper end portion 40 a of the locking projection 40 can be lifted up to a point where it contacts the inclined guide portion 50 a of the upper regulating member 5. . At this time, if an upward force is applied to the shaft body 4, the locking projection 40 comes into contact with the inclined guide portion 50a, and in this state, moves to the stopper portion 50b along the inclined guide portion 50a.
Here, the shaft 4 of the door side hinge 1a attached to the lower side of the door 7 may be pushed up in the same manner, but the lower door side hinge 1a and the door frame side hinge 1b are fitted together. Since this is not a very difficult operation, the shaft body 4 may be left in the most protruding state. Here, an example will be described in which only the shaft body 4 of the upper door side hinge 1a is pushed up and the shaft body 4 of the lower door side hinge 1a is operated in the most protruded state.

The installer may release the hand from the shaft body 4 when the rotational movement of the shaft body 4 lifted upward stops. Then, the shaft body 4 automatically moves downward due to the weight of the shaft body 4 or the urging force of the urging means 10, and the first locking groove along the first inclined guide portion 60a of the lower regulating member 6 located immediately below. To 60b. This state is shown in FIGS. 1B and 5C.
When the shaft body 4 of the door side hinge 1a attached on the upper side is in a half-locked state in which the shaft body 4 is protruded by about a little less than half, the door 7 is first lifted and the door frame attached to the lower side of the door frame 8 first. The door side hinge 1a attached to the lower side of the door 7 is fitted into the side hinge 1b.

And the door 7 is moved to the fitting position with the door frame side hinge 1b attached to the upper side as it is.
Then, the end of the cylindrical portion 3b of the door frame side hinge 1b hits from the side surface side of the shaft body 4 in a semi-locked state, and the tip 41 is actuated to push the shaft body 4 upward, whereby the first locking The locking at the groove 60b is released. Here, since the tip side of the shaft body 4 is gradually tapered to a tapered shape 41, the position of the tapered portion 41 does not always change regardless of the rotational position of the cylindrical shaft body 4, and the cylindrical portion 3b. The shaft body 4 can be made to act so as to push up smoothly.
This state is shown in FIG. 1 (c) and FIG. 6 (a).
The upper end portion 40a of the locking protrusion 40 of the shaft body 4 lifted again in this manner moves along the inclined guide portion 50a of the upper regulating member 5 to the stopper portion 50b, and then the weight or urging force of the shaft body 4 is reached. The shaft body 4 moves downward by the urging force of the means 10 and is guided to the second locking groove 60d along the second inclined guide portion 60c of the lower regulating member 6.
The shaft body 4 in a state of being locked in the second locking groove 60d is inserted into the cylindrical portion 3b of the door frame side hinge 1b, and the cylindrical portions 3a and 3b are connected in the axial direction. The suspension of the door 7 is completed. This state is shown in FIG. 1 (d) and FIG. 6 (b).

  According to this configuration, when the door 7 is suspended, the shaft body 4 of the door side hinge 1a is set in a semi-locked state, and the door 7 is inclined to the fitting position of the door frame side hinge 1b attached on the upper side. If it moves, the shaft body 4 automatically moves downward, and the shaft body 4 can be communicated with the door side hinge 1a and the door frame side hinge 1b. That is, since it is not necessary to manually raise and lower the shaft body 4, the door 7 can be suspended while the door 7 is held with both hands. Even if it exists, the suspension of the door 7 can be performed simply and safely.

The hinge 1 in the present embodiment is not limited to the indoor door 7 shown in the figure, but can be a hinge 1 used for a door or an opening window attached to the front opening of the furniture. The size, structure, etc. are not limited to the illustrated examples.
Further, when the biasing means 10 is provided as described above, the installation direction of the hinge 1 is not limited to the pattern shown in the figure, and for example, the hinge 1 can be provided so as to be able to protrude and retract in the lateral direction from the cylindrical portion 3a.
Furthermore, the configuration of the locking guide mechanism 60 is also limited to an example in which four sets of the first inclined guide portion 60a, the first locking groove 60b, the second inclined guide portion 60c, and the second locking groove 60d are configured as shown in the figure. The number may be other numbers such as one set and two sets.
