Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge mounted on an opening frame and a door for holding the door in a freely rotatable manner.
The present invention relates to a hinge that is not required to be replaced even when the door is used upside down, and is convenient for a left-right door.

[0002]

2. Description of the Related Art Conventionally, as hinges used for doors, there are many hinges which can be separated from an opening frame side half portion attached to an opening frame and a door side half portion attached to a door side, and can be vertically inserted and removed. When viewed from the side where the door is opened, there are two types of hinges: “for left suspension” where the hinge is located on the left side, and “for right suspension” where the hinge is located on the right side. It was not possible to use both for "left suspension" and "right suspension".

[0003] Therefore, it is generally necessary to designate "for left suspension" or "for right suspension" at the time of ordering a door. A hinge corresponding to the designation is previously attached to the opening frame or door, and the door is shipped. I have. Therefore, at the time of packing, “open for left hanging” or “for right hanging” is displayed on both of the opening frame and the door, but it may still be incorrectly delivered at the time of delivery. In addition, two types of products are required for each type: "for left suspension" and "for right suspension". Manufacturers also require "for left suspension" and "for right suspension". We had to go ahead with operations while forecasting demand for what the production ratio would be.

Further, when the opening direction of the door once installed is changed due to a reform or the like, it is impossible to change left and right at all by the above-mentioned conventional hinge. On the other hand, the applicant and others have proposed hinges that can be used for both the left and right sides (Japanese Utility Model Laid-Open No. 4-52177, Japanese Utility Model Laid-Open No. 4-4107).

5, Heikai 5-75378).

[0005] As one of the hinges which can be used for both left and right, there is a hinge called a flag hinge. This is, as shown in FIG. 8, an opening frame side half 91 having a vertical axis X attached to the opening frame.
A vertical shaft tube P fitted to the vertical shaft X, which is attached to the door
The door-side halves 92 having are turned upside down or turned over in the same plane so that they can be used for both left and right.

FIG. 9 (JP-A-48-592)
43, JP-A-59-128876, etc.), each of which has a vertical shaft cylinder P, and the two halves 95 have one vertical axis X,
As shown in FIG. 10, both the opening frame 10 and the door 20 are turned upside down, and the position of the barrel can be changed by reversing in the same plane, as shown in FIG. Is configured. This is because the door side half is formed symmetrically with respect to the plane that bisects the front and back of the door, and it is attached evenly to both sides of the door, so the door is turned around the vertical center line as an axis. If the vertical shaft X and the vertical shaft cylinder P are mounted so that they always come to the side where the door is opened, they can be converted into either "for left suspension" or "for right suspension".

That is, according to this, for example, when the door is once mounted on the door and the opening direction of the door needs to be changed, first, the fixing screws on the door side half are all removed, After being separated from the door, it is turned over, etc., and is attached to the door again. As described above, the opening direction of the door can be changed. However, as described above, there is a problem in that considerable trouble such as removal and re-attachment of all fixing screws is required.

In addition, due to the change in the mounting direction of the hinge, if the screws are insufficiently tightened at the time of re-installation, or if the same mounting holes are used, the holding force of the screws is greatly reduced. In the worst case, the door may fall off.

[0009] After all, to change the hinge mounting direction on site, the work load is too large, especially in a short time.
In the construction of an apartment house with a large number of doors, the increase in burden becomes even more remarkable and is virtually impossible. Therefore, even if it is referred to as both left and right, it is actually attached to the door in advance at the time of shipment from the factory, and the mounting direction such as “for right suspension” and “for left suspension” is displayed on the package. Conventional processing is still common today.

[0010] In addition, regarding the decrease in the holding force of the screw, supplementarily, a screw having a hinge attached to the door body (4 to 6 wood screws of about 30 to 40 mm is required for reasons of strength). If the screw is not completely screwed in, the door will loosen due to opening and closing, and if it is used for a long time, it may fall off. Power tools such as a driver are required. Depending on the skill of the operator, the screwing is insufficient and the strength may be reduced. Further, since the hinge is once removed and re-attached, a large number of traces of the attachment hole remain on the door, which may impair the aesthetic appearance and decrease the holding power of the wood screw.

In addition, a horizontal insertion / removal type is called
A left / right dual-use type has been proposed in which an insertion opening is provided in the door side half of the door so that a horizontal piece of the opening frame side half can be inserted from the front and back of the door (Japanese Patent Laid-Open No. 9-317300). This is because when the direction of opening the door at the construction site is changed, it is not necessary to temporarily remove and reattach the half of the door to the door, but if the fixing screw on the horizontal piece is loosened , The door may fall off. In addition, since the position of the opening frame side half cannot be changed, the opening frame cannot be used for both left and right. Therefore, the left and right opening frames are required separately.

Considering the packing at the time of transporting the door, the one shown in FIGS. 8 to 10 has a problem in that the vertical barrel P projects from the door, so that the hinge may be damaged or the packing becomes large. There is. The door handle L can be easily removed at the time of transportation because it is attached with one screw, but the hinge requires four to six wood screws and takes a lot of time to remove. Is generally shipped in a state where it is attached to a door in advance.

That is, since the hinged vertical barrel P projects from the door body as shown in FIG. 10, it is easily deformed and damaged by an external impact. Further, as shown in FIG. 11, in order to protect the protruding hinged vertical barrel P, a hinge protecting cushioning member 102 is required in addition to the door packing cardboard 101. Further, since the plane portion other than the vertical shaft cylinder P is a hollow portion, the height adjusting cushioning material 10 is also provided in this portion.
It requires a filler such as 3. Therefore, as shown in FIG. 12, the thickness of the packing is twice or more as compared with the case where the door is packed alone, and the amount of the cushioning material is also increased. In addition, since the hollow portion is large, lamination in a packaged state tends to be unstable, and there is a risk of collapse of the load particularly when transporting a truck or the like.

Also, in the case of a hinge that can be inserted and removed as shown in FIGS. 8 to 10, the door is once lifted and attached so that the vertical barrel P is dropped onto the vertical axis X on the opening frame side. Requires a space longer than the length of the vertical axis X. If there is no space of at least about 10 cm, the door cannot be mounted, and there is a problem that mounting may be difficult depending on the surrounding conditions.

[0015]

FIG. 1 is a front view of a door, FIG. 2 is a perspective view showing an embodiment of the present invention, and FIG. FIG. 4 is a cross-sectional view illustrating an embodiment, and FIG. 4 is a cross-sectional view illustrating a state where a shaft member is mounted on a door-side base member.

Referring to FIG. 1, the opening frame 10 will be described first. The hinge-side vertical frame member 11 having a pair of upper and lower hinges H, H for holding the door 20 in a rotatable manner, and the handle L turning the door. A latch receiving member R2 capable of receiving the latch R1 which advances and retreats from 20, and a hinge receiving side vertical frame member 12 having the same length as the hinge side vertical frame member 11, is inserted and coupled between the upper ends of both. An upper frame member 13 is provided.

The hinge H includes an opening frame side half portion attached to the opening frame 10 and a door side half portion 50 attached to the door 20. Although the illustration of the opening frame side half is omitted here, for example, the opening frame side half 9 shown in FIG.
At least one as in (1 in this embodiment)
Vertical axis X is provided. Further, the door-side half 50 is provided with at least one (one in the present embodiment) vertical shaft cylinder P which is fitted to the vertical axis X. The door-side half 50 is connected to the opening frame-side half 91 via the vertical shaft cylinder P.
And pivotally connected about a vertical axis X, whereby the door 2
0 is rotatably held.

More specifically, the door-side half 50 will be described.
Has a door-side base member 51 and a shaft member 52.
The former door-side base member 51 is embedded at the end of the door 20 and is fixed by a plurality of screws without protruding from the door 20. That is, the width is equal to the width of the end face of the door 20 and does not protrude from the end face of the door 20 toward the opening frame 10. The latter shaft member 52 is separable from the door-side base member 51, and includes a vertical shaft cylinder P and an insertion plate 53 formed by connecting the vertical shaft cylinder P to a distal end portion. The vertical barrel P may be formed integrally with the insertion plate 53 as in the present embodiment, or may be a separate vertical barrel P coupled thereto. Hole 53a in insertion plate 53
And a rectangular opening 5 at the rear end.
3b is provided.

A slit 51a penetrating from the front side to the back side of the door 20 is formed in the door side base member 51, and the rear end of the insertion plate 53 is formed in the slit 51a by the front side of the door 20 (right side in FIG. 3). From behind (Fig. 3
At the left). The door side base member 51 is provided with a lock mechanism for locking the insertion plate 53 guided by the slit 51a.

The lock mechanism includes spring springs 31 and 32.
Sets of locks 3 projecting toward the slit 51a through the
3,34. The contact portion 33a of the lock 33 on the front side of the door 20 is smoothly inclined so that the protrusion becomes smaller from the rear side of the door toward the front side, and the insertion plate 53 is
Only when guided to the front side of the door 20 by the door 1a, it comes into contact with the rear end of the insertion plate 53, contracts, and
Is stored on the opposite side. On the other hand, door 2
The abutting portion 34a of the lock 34 on the back side is smoothly inclined so that the protrusion becomes smaller from the front side to the back side of the door, and the insertion plate 53 is guided only when the insertion plate 53 is guided by the slit 51a from the back side of the door 20. The rear end of the slit 53 is contracted and contracted to be stored on the side opposite to the slit 51a. Therefore, the lock 33 remains in the protruding state even when the rear end of the insertion plate 53 guided from the back side of the door 20 abuts on the slit 51a. Similarly, the lock 34 guides the slit 51a from the front side of the door 20. Even if the inserted rear end portion of the insertion plate 53 comes into contact with the insertion plate 53, the insertion plate 53 remains in the protruding state.

The slit 5 of the door side base member 51
Opening windows 35 and 36 used to release the lock by the locks 33 and 34 are formed at positions facing the locks 33 and 34 with 1a therebetween.

The springs 31, 32 normally extend and press the locks 33, 34 so as to project toward the slit 51a. At this time, as shown in FIG. 3, the rear end of the insertion plate 53 is guided by the slit 51 a from the front side of the door 20, and when the rear end of the insertion plate 53 comes into contact with the lock 33, the lock 33 is compressed. This contracts in the direction in which it is stored (upward in FIG. 3), and this state is maintained while the lock 33 contacts the plate surface of the insertion plate 53.

When the position of the hole 53a provided in the insertion plate 53 reaches the position of the lock 33 according to the guide of the insertion plate 53, the lock 33 projects from the hole 53a by the pressing force of the spring spring 31 from the storage position. To lock the insertion plate 53. At this time, the lock 34 in the protruding state is housed inside the opening 53b of the insertion plate 53 so as not to contact the plate surface of the insertion plate 53, so that the lock 34 is in the protruding state and is not locked. . In order to release the lock by the lock 33, a bar-shaped tip of a driver or the like is locked from the open window 35 of the door-side base member 51 to the hole 53 a of the insertion plate.
This is done by abutting against and pushing. That is, the extended spring spring 31 is contracted, and the lock 33
Is returned to the storage position, so that the lock is released. Although it is possible to easily remove the lock 33 by pushing it with a fingertip, a tool such as a screwdriver is used because it is dangerous if a child pushes carelessly and the hinge comes off.

Conversely, the rear end of the insertion plate 53 is
Guided from the back side to the slit 51a, the insertion plate 53
When the rear end contacts the lock 34, the lock 34 is retracted by the action of the contraction of the spring 32, and this state is maintained while the lock 34 contacts the plate surface of the insertion plate 53. When the position of the hole 53a provided in the insertion plate 53 reaches the position of the lock 34 according to the guide of the insertion plate 53, the lock 34 projects from the hole 53a and locks the insertion plate 53. At this time, the lock 33 in the protruding state is connected to the opening 5 of the insertion plate 53.
3b, so that it does not come into contact with the plate surface of the insertion plate 53, it is in a protruding state and is not locked. Similarly, in order to release the lock by the lock 34, the rod-shaped tip of a driver or the like may be brought into contact with the lock 34 and pushed in.

According to the hinge configured as described above, the shaft member 5 in which the vertical shaft cylinder P is connected to the insertion plate 53
2 is a detachable type with respect to the door-side base member 51, and can be easily attached from the front side and the back side of the door 20. Can quickly respond to the request. Further, since the shaft member 52 can be removed at the time of packing, the vertical shaft cylinder P does not protrude to the front side or the back side of the door, and as shown in FIG. can do. Therefore, packaging is simple without particularly needing a cushioning material or the like.

In this embodiment, the lock mechanism is constituted by using two sets of locks 33 and 34 and springs 31 and 32. However, one set of lock and spring is provided at the center of the door side base member 51. You may bring it. Although the open windows 35 and 36 are provided, the entire end side of the door 20 may be opened.

Next, a hinge according to a second embodiment of the present invention will be described with reference to FIGS. The same parts as those of the hinge according to the above-described first embodiment are denoted by the same reference numerals. The hinge according to the second embodiment of the present invention includes an opening frame side half that is attached to the opening frame 10 and a door side half 70 that is attached to the end of the door 20, and the vertical provided on the opening frame side half. The door-side half 70 is rotatable around the vertical axis X via the axis X and the vertical shaft cylinder P provided on the door-side half 70, which is fitted to the vertical axis X. The hinge according to the first embodiment is common to the hinge according to the first embodiment in that the door 20 is connected so as to be rotatably held with respect to the opening frame 10.

However, with respect to the door-side base member 71 buried at the end of the door 20 without protruding from the door 20, the shaft member 72 formed by connecting the vertical shaft cylinder P to the tip of the insertion plate 73 is provided. The hinge according to the first embodiment is significantly different from the hinge according to the first embodiment in that the hinge is integrated so as not to be separated.

That is, upper and lower rail grooves 71a and 71b are formed on the upper and lower sides of the door-side base member 71, and the upper and lower rail grooves 71a and 71b are formed with protrusions 73c and 73d provided on the upper and lower portions of the rear end of the insertion plate 73. Are movably fitted on the front side and the back side of the door 20. Further, an insertion plate 73 fitted in the upper and lower rail grooves 71a, 71b.
A total of four stoppers 75 are provided at the top and bottom, respectively, to make the projections 73c and 73d of the first and second projections 73d and 73d unable to fall off.

The projections 73c and 73d of the insertion plate 73 are guided to the position of the door-side base member 71 which vertically connects the middle of the upper and lower rail grooves 71a and 71b.
As shown in FIG. 7, the entire shaft member 72 is rotated from the front side of the door 20 (right side in FIG. 7) to the back side of the door 20 (left side in FIG. 7), or vice versa. , A vertical groove 76 is formed to be rotatable. The vertical groove 76 has a depth capable of storing the entire insertion plate 73. Thus, the packing can be performed relatively easily since only the portion of the vertical barrel P can be left. Further, the springs 31 and 32, which are lock mechanisms for locking the insertion plate 73 guided in the same manner as the first embodiment, are
3 and 34 are provided.

The movement of the shaft member 72 from the front side to the back side of the door 20 will be described. As shown in FIG. 6, a rod-like tip portion such as a screwdriver is inserted into a hole 73a provided in an insertion plate 73 of the shaft member 72 locked. When the door 20 is pressed against the lock 33 on the front side of the door 20, the lock is released. Then, the insertion plate 73 is horizontally moved to the front side of the door, and the projection 73c,
73d is brought to the vertical groove 76, and the space of the vertical groove 76 is used, and the projection 73c, 73d is rotated to the back side of the door 20 around the rotation axis (clockwise rotation in FIG. 7). Thereafter, when the insertion plate 73 on the back side of the door 20 is horizontally moved to the front side of the door 20, the lock 34 on the back side of the door 20 is locked in the hole 73a of the insertion plate 73, and the movement is completed. For the movement from the back side of the door 20 to the front side,
You can do the opposite. The opening 73b provided in the insertion plate 73 plays the same role as the opening 53b of the first embodiment.

In the embodiment of the present invention, a combination of the springs 31 and 32 and the locks 33 and 34 is used as the lock mechanism. However, even if the spring member is used, for example, the lock 33 may be used instead. , 34 as plate springs and the spring springs 31, 32 may be omitted.
