Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to hinges.

[0002]

2. Description of the Related Art A hinge has a pair of blades which are respectively connected to two members to be rotatably connected to each other, and a pivot on which a shaft tube portion provided on one side of each blade is loosely fitted. It is composed of. As this hinge, there is generally known a hinge provided with a flange portion at which the end surface of the shaft tube portion of each vane abuts at a central position in the axial direction of the pivot shaft (see Japanese Patent Publication No. 47-46288). In this way, in the case of a hinge that has a collar on the pivot,
Since the collar portion is sandwiched between the shaft tube portions of the two vanes, there is no problem of slipping of the pivot.

By the way, when the door is connected to the pillar at two upper and lower positions by using the above-mentioned hinge, it is usual that different hinges are used at the upper and lower sides.

That is, in this case, the vanes are connected to the upper and lower parts of the pillar and the door, respectively, and the lower halves of the pivots are inserted into the axial tube portions of the upper and lower vanes on the pillar side, respectively. Generally, a method of fitting each axial tube portion of the upper and lower vanes on the side to the upper half of the upper and lower pivots on the pillar side is adopted. At that time, it is difficult to simultaneously align the axial tube portions of the upper and lower vanes on the door side with the upper and lower pivots of the pillar side.
Therefore, for example, a hinge with a long pivot is used in the upper part of the door, and a hinge with a short pivot is used in the lower part. In other words, in this case, the fitting start position between the upper half of the pivot and the shaft tube portion shifts in the axial direction between the upper part and the lower part, and the shaft tube part of the upper vane on the door side first moves to the pillar side. It is possible to align and fit a part to the upper pivot, and then to align and fit the shaft tube part of the lower vane on the door side to the lower pivot on the pillar side. .

Of course, not only the above door, but when connecting two members by a plurality of hinges, when it is difficult to align the shaft tube portion and the pivot, different types of hinges are usually adopted. is there.

[0006]

However, as described above,
Using a plurality of different types of hinges means that if they are used incorrectly, for example, with respect to the door, the upper hinge will be aligned first, but the lower side will be aligned first. This means that the workability of the operator is lost and the workability of the worker is deteriorated. In addition, the parts management becomes complicated, and the manufacturing cost of the hinge is high.

Further, in the case of the door, there are right-handed (right-handed) and left-handed (left-handed), but in contrast to this, it is necessary to prepare hinges for right-hand use and left-hand use, This further exacerbates the problems of workability, part management and manufacturing cost described above.

That is, an object of the present invention is to increase the versatility of the hinge. Specifically, the first problem is to make it possible to use one kind of hinge in two kinds of modes in which the fitting start positions of the pivot shaft and the shaft tube portion are different, such as for the upper part and the lower part of the door. The second problem is to make it possible to use one type of hinge for both the right opening and the left opening.

[0009]

According to the present invention, in order to solve the above-mentioned first problem, the lengths of the shaft portions projecting in both directions from the collar portion of the pivot are different, and the orientation of this pivot is the use of a hinge. By changing the position depending on the position, the fitting start position of the pivot and the shaft tube portion can be changed. For the second problem, double-sided spot facing is performed in the screw insertion hole of the blade of the hinge. Is applied.

That is, specifically, therefore, a pair of blades each having a shaft tube portion on one side and respectively coupled to two members to be rotatably connected, and the shaft tube portions of both blades. A hinge having a first shaft portion and a second shaft portion that are selectively inserted into the shaft, and a pivot having a collar portion that abuts against the end surface of each shaft tube portion between the shaft portions. The lengths of the first shaft portion and the second shaft portion are made different from each other, and the both blades are selectively assigned to the shaft portions having different lengths so that the shaft tube portions are loosely fitted. Further, each of the pair of blades is formed with a screw insertion hole for coupling with two members to be rotatably connected, and the screw insertion hole is formed in the peripheral edge of both sides of the blade. Each has a seat surface.

(Operation) In the present invention, when two members are connected using two hinges, one blade of each of the two hinges is connected to one member, and the axial tube of these blades is connected. When the pivots are inserted in the parts so that they are oriented in opposite directions, the first shaft part and the second shaft part having different lengths are projected from the shaft tube parts of the blades. That is, the fitting start positions of the shaft tube portions of the two blades coupled to the other member and the respective pivots are displaced in the axial direction, and after the shaft tube portion and the pivot axis of one hinge are aligned, The other hinge can be aligned with the shaft tube portion and the pivot.

Moreover, since seating surfaces are formed on both sides of the vane, by changing the mounting surface of the vane,
The hinge can be used for both right opening and left opening.

[0013]

Therefore, according to the present invention, since the length of the first shaft portion and the length of the second shaft portion protruding from the collar portion of the pivot shaft are different from each other, by changing the direction of the pivot shaft, Two types of hinges can be used, such as one for the upper part of the door and one for the lower part of the door, in which the fitting start position of the pivot and the axial pipe part is shifted in the axial direction. Workability is improved, parts management is easy, and manufacturing cost can be reduced. Moreover, since the seat surfaces are formed on both sides of the blade for the screw insertion holes of the blade, one type The hinge can be used for both right-opening and left-opening, even when the rotation directions are different, increasing the versatility of the hinge and improving workability, managing parts, and reducing manufacturing costs. Will be advantageous.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

-Embodiment 1-This embodiment is shown in FIGS. 1 to 5.

FIG. 1 is an exploded perspective view of the flag hinge 1. The flag hinge 1 includes a pair of upper and lower blades 2 and 2 connected to each of two members to be rotatably connected, and the blades 2 and 2.
It has a pivot 3 to which 2 is attached, and upper and lower caps 4 and 4 attached to the vanes 2 and 2.

As shown in FIGS. 2 and 3, the vanes 2 and 2 are rectangular in shape and have shaft tube portions 6 and 6 open at both ends on each side. Each blade 2 is formed with a plurality of screw insertion holes 7 for screwing to each member to be connected. Then, a counterbore is applied to the opening peripheral edge portions of both surfaces of the blade of the screw insertion hole 7, and seat surfaces 7a, 7a for screws are formed on the both surfaces.

The pivot 3 is a shaft tube portion 6 of each of the vanes 2 and 2.
A flange portion 10 provided with a first shaft portion 8 and a second shaft portion 9 that can be selectively inserted into the shaft 6, and the shaft portions 8 and 9 are in contact with the end faces of the shaft pipe portions 6 and 6 in the middle. It is provided in series via. Then, the first shaft portion 8 is formed so that the length from the flange portion 10 is shorter than that of the second shaft portion 9.

The cap 4 is composed of a circular head portion having substantially the same size as the outer diameter of the shaft tube portion 6 of the blade 2, and a leg portion fitted into the shaft tube portion 6.

FIG. 4 shows an example of use of the flag hinge 1. This is an example in which the door 12 is rotatably connected to the pillar 11 of the building at two locations, upper and lower, with right-handedness.

That is, first, two flag hinges 1 and 1 are prepared, and one blade 2 of each flag hinge 1 is connected to a pillar 11 and the other blade 2 is connected to a door 12 by screws. In this case, since the vane 2 has the seating surfaces 7a formed on both sides with respect to the screw insertion hole 7, either side of the two sides can be brought into contact with the pillar 11 or the door 12 to be joined thereto. .

Next, the pivots 3, 3 are fitted into the respective axial tube portions 6, 6 of the upper and lower vanes 2, 2 on the side of the pillar 11. In this case, the first shaft portion 8 of the pivot 3 is fitted into the upper blade 2 and the second shaft 9 of the pivot 3 is fitted into the lower blade 2. As a result, the longer second shaft portion 9 projects upward from the upper vane 2 of the pillar 11, and the shorter first shaft portion 8 projects upward from the lower vane 2. .

Then, the door 12 is lifted up, and the shaft tube portion 6 of the upper vane 2 is aligned with the long second shaft portion 9 protruding from the upper vane 2 of the pillar 11 and partially fitted. Then, the shaft tube portion 6 of the lower blade 2 of the door 12 is aligned with the short first shaft portion 8 protruding from the lower blade 2 of the pillar 11, and the door 12 is lowered as it is. The shaft tube portion 6 and the pivot shaft 3 are completely fitted at both the upper and lower portions.

The cap 4 can be fitted in advance on the shaft tube portion 6 of each blade 2 (for example, at the manufacturing stage).

In the above embodiment, the vane 2 on the upper side of the pillar 11
Although the longer second shaft portion 9 is projected from the lower blade and the shorter first shaft portion 8 is projected from the lower blade 2, this may be reversed, and the operator can freely set it on site. Can be decided.

FIG. 5 shows an example in which the door 12 is attached to the pillar 11 by left hand. In this case, flag hinge 1
As described above, since the seating surfaces 7a are formed on both sides of the blade 2 with respect to the screw insertion hole 7 of the blade 2, the contact surface of the blade 2 should be reversed from the example shown in FIG. You will understand that it is good.

When the seating surface of the screw insertion hole is formed on only one surface of the vane 2, the pillar 11 and the door 1 in the example of FIG.
If you replace the blades 2 and 2 that were respectively connected to 2 and 2,
The door 12 can be attached left-handed.

-Embodiment 2-This embodiment is shown in FIGS. 6 to 8 and includes a two-pipe hinge 2.
1 is an example.

The two-pipe hinge 21 of this example has a blade 22 different from that of the first embodiment, and the pivot and the cap are the same as those of the first embodiment.

That is, the blade 22 has the shaft tube portion 26 in the upper half (or the lower half) of one side thereof, and the remaining half is a notch. Further, as in the first embodiment, the blade 22 has the screw insertion hole 2 having seat surfaces 27a, 27a on both sides.
7 are formed.

Therefore, in the case of this example, as can be understood by seeing FIG. 6 and FIG. 8, the two-pipe hinge 21 is similar to the first embodiment by reversing the vertical direction of the pivot shaft 3. On the door 12
It can be used for both upper and lower uses. However, since the seat surface 27a of the screw insertion hole 27 is provided on only one surface, the two-hand hinges for right-hand use and left-hand use are separate.

In each of the above-mentioned embodiments, examples of use in which a door is attached to a pillar have been described, but it goes without saying that the present invention can also be applied to attachment of a lid of a container and rotary parts in various machines or devices.
