[Industrial applications]

 This invention relates to hinges. In particular, the present invention relates to a hinge used when attaching a hinged door such as a door, and a hinge that can easily adjust a slight gap between the frame and the door after attachment.

[0002]

[Prior art]

 Various hinges are already known as hinges. The simplest one is two blades connected by a shaft that can be opened and closed freely. The two blades have a symmetrical shape, so either blade may be attached to the door side. It is considered as a structure. A hinge with such a structure has been said to have a large number of screw holes formed in each of two blade plates, and to be fixed directly to the frame and door with screws. With a hinge having such a structure, it is easy to adjust the left and right slight gaps between the frame and the door even after attaching to the frame, and the gap between the door and the top frame or floor. It wasn't. In order to adjust these gaps, the hinge had to be replaced from the beginning, so careful attention was required when attaching the hinge.

Therefore, there has been proposed a hinge in which the gap between the door and the frame can be adjusted after the hinge is attached. In this type of hinge, in addition to the original hinge, a fixed block is installed in advance on the frame side, and the blade plate of the hinge attached to the door side is attached to the fixed block. The mechanism was designed to facilitate position adjustment by causing a slight deviation between them. Such a proposal is described in, for example, Japanese Utility Model Publication No. 5-22787 and Japanese Utility Model Publication No. 5-78868. However, the hinges described in these publications have a drawback that the structure is complicated. Further, since the structure is complicated, there is a drawback that looseness is likely to occur between the parts.

[0004]

[Problems to be solved by the device]

 As described above, there have been merits and demerits in the conventional hinges. Therefore, there is a demand for a hinge that can adjust the gap between the door and the frame, can be easily attached to the door and the frame, has a simple structure, has no rattling, and can be provided at a low cost. This invention aims at providing a hinge suitable for such a demand.

[0005]

[Means for Solving the Problems]

 This invention is an improvement of a hinge composed of a hinge portion and a fixed block, as taught by Japanese Utility Model Laid-Open Nos. 5-22787 and 5-78868.

In the above publication, the two blades of the hinge are slidable on the shafts where they are connected to each other, so that the hinge itself and the fixed block have a complicated structure. It is easy to loosen the connection between the section and the fixed block. Therefore, in this invention, the position of the door with respect to the frame can be adjusted by sliding between the fixed plate attached to the frame side and the hinge instead of sliding on the shaft, thereby simplifying the structure. It was also improved so that there would be no backlash.

According to the present invention, an engaging portion is formed at one end of a blade plate that constitutes a hinge portion, and the other fixing block is a fixing plate that is simply a flat plate provided with grooves and holes. The essence is that the locking part of the hinge part is recessed into the groove so that it can slide in the axial direction of the hinge part. In addition, the locking part is recessed in the groove to prevent the locking part from floating from the groove, and the opening angle between the vane plate and the fixed plate with the locking part as a fulcrum is attached on the fixed plate. The essence is that it can be set freely according to the degree of appearance of screws.

This invention is a hinge comprising a hinge portion formed by connecting two blade plates with a shaft so as to be openable and closable, and a fixing plate fixed to one of the two blade plates. The tip part extending parallel to the axis of one of the blades is bent to provide a locking part with a uniform cross section, and the fixed plate slides the blade while locking the locking part on its surface. The present invention relates to a hinge characterized by forming a groove and additionally providing a retractable screw for inclining the blade plate with the locking portion as a fulcrum.

【Example】

 An example of the hinge according to the present invention will be described with reference to the drawings as follows. FIG. 1 shows a hinge part in a hinge according to the present invention, (a) is a plan view and (b) is a side view. 2A and 2B show a fixing plate in a hinge according to the present invention. FIG. 2A is a plan view thereof, and FIG. 2B is a sectional view taken along line BB in FIG. 3A and 3B show the locking relationship between the hinge portion and the fixing plate in the hinge according to the present invention, FIG. 3A is a plan view, and FIG. 3B is a sectional view taken along line BB in FIG. FIG. 4 shows a usage state of the hinge according to the present invention, (a) is a plan view thereof, and (b) is a sectional view taken along line BB in (a). FIG. 5 is a cross-sectional view showing a state in which the hinge is projected from the fixing plate and the vane plate is inclined in the hinge according to the present invention.

In FIG. 1, the blade plate 1 and the blade plate 2 are openably and closably coupled by a shaft 3 to form a hinge portion x. In the portion where the blades 1 and 2 are connected to the shaft 3, like the conventional hinge, the ends 11 and 12 of the blades, which are curved in a cylindrical shape, are alternately positioned, and the shaft 3 is located there. It is pierced and can be opened and closed freely. A ring 13, which is made of plastic, particularly polyolefin, is interposed between the curved cylindrical portions 11 and 12 to facilitate opening and closing.

The blade plate 1 is a portion fixed to the door side, and the blade plate 2 is a portion fixed to the frame side. A tip portion of the blade plate 2 extending in parallel with the axis 3 is bent in a cross-section to form a locking portion. The locking portion is composed of an oblique portion 21 that obliquely protrudes from the blade plate 2, and a parallel portion 22 that protrudes in parallel with the blade plate 2 at the tip thereof.

The vane plate 1 is provided with a screw hole 14 for fixing to the door. The blade plate 2 is provided with a screw hole 23 for temporarily fixing to the fixed plate, a screw hole 24 for fixing the fixed plate and the frame, and a screwdriver for rotating the screw attached to the fixed plate. A screw hole 25 for inserting is additionally provided. Each of these holes 23 to 25 on the blade 2 is a long hole extending in the direction in which the shaft 3 extends. It is desirable that the shape of the holes be the same. However, the taper direction around the hole is different from the other screw holes 23 and 24 only in the screw hole 25, and is opposite to the protruding direction of the oblique portion 21.

FIG. 2 shows the fixed plate y. The fixing plate y is provided with a groove 4 on the surface, and one side of the groove 4 having an end is projected to form a projecting portion 41 for narrowing the opening of the groove 4, and the inner surface 42 of the projecting portion 41 has a fixed plate. It is flush with the surface of y. The height t of the protrusion 41 is the same as the thickness t of the blade plate 2. The groove 4 is large enough to accommodate the locking portion of the vane plate 2, that is, the oblique portion 21 and the parallel portion 22. Further, the groove 4 is provided so as to penetrate through the fixed plate y in the longitudinal direction. The groove 4 has a semicircular cross section, and it is preferable that the groove 4 has a hook-shaped protrusion formed in the diameter direction of the opening.

As shown in FIG. 2, the fixed plate y has a large number of through holes. Among them, the via hole 43 is for fixing the fixing plate y to the frame side. The screw hole 44 is for temporarily fixing the blade plate 2 to a fixing plate fixed to the frame side, and is for receiving a screw inserted from the screw hole 23 of the blade plate 2. The screw hole 45 is for inserting the screw 6, and the screw 6 can be retracted from the fixed plate y. The screw hole 46 is for fixing the blade plate 2 and the fixed plate y to the frame.

To attach the hinge according to the present invention between the door and the frame, the hinge portion x is attached to the door on the one hand, and the fixing plate y is attached to the frame on the other hand. In order to attach the hinge part x to the door, it is sufficient to insert a screw into the screw hole 14 of the blade 1 and stop it as in the conventional case. To attach the fixing plate y to the frame, the screw 5 is inserted into the screw hole 43 and fixed. At the same time, the screw 6 is inserted into the screw hole 45 of the fixing plate y and embedded.

After that, as shown in FIG. 3, the hinge part x fixed to the door D is brought close to the fixing plate y fixed to the frame F, and the parallel part 22 and the oblique part 21 of the blade plate 2 are fixed to the fixing plate y. Insert it into the groove 4. At this time, the surface of the parallel portion 22 is fixed in close contact with the inner surface 42 of the projecting portion 41, but since the groove 4 penetrates into the fixed plate y, the blade plate 2 is grooved along the fixed plate y. 4 can be slid in the extending direction. Thus, the position of the hinge part x and the fixing plate y in the direction in which the shaft 3 extends, that is, the vertical direction of the door D can be adjusted. As a result, adjustment can be made between the door D and the top frame and floor.

After adjusting the vertical direction in this way, the screw 7 is inserted from the screw hole 23 of the blade plate 2 and passed through the screw hole 44 of the fixed plate to temporarily fix the blade plate 2 to the fixed plate y. At this time, since the screw hole 23 is a long hole, the blade 7 can be reliably fixed to the fixed plate y by the screw 7 even after the position adjustment.

After that, a screwdriver is inserted into the screw hole 25 of the blade plate 2, the screw 6 is rotated from above the blade plate 2, and the screw 6 is projected and retracted from the fixed plate y. At this time, since the screw hole 25 is a long hole, the tip of the screwdriver can be brought into contact with the screw 6 even after the position adjustment, like the screw 7. Since the periphery of the screw hole 25 is inversely tapered, the head of the screw 6 surely abuts around the screw hole 25 to support the blade plate 2. That is, when the screw 6 is protruding, as shown in FIG. 5, the blade plate 2 changes its inclination with respect to the fixed plate y with the oblique portion 21 and the parallel portion 22 as fulcrums. As a result, the lateral gap between the door D and the frame F can be adjusted.

The inclination of the vane plate 2 with respect to the fixed plate y is determined by the degree to which the head of the screw 6 projects from the fixed plate y. Therefore, it is preferable to mark a part of the head of the screw 6 to determine how much the screw 6 should be rotated and how much the head should protrude.

After the vertical and horizontal adjustments are completed in this way, the screws 8 are inserted into the screw holes 24 to obtain the state shown in FIG. At this time, since the screw hole 24 is a long hole, the blade plate 2 can be securely fixed to the fixed plate y and the frame F with the screw 8 even after the position adjustment. As a result, the hinge according to the present invention is used in the state shown in FIG.

[0021]

EFFECTS OF THE INVENTION According to the present invention, since the hinge part and the fixed block are provided separately, the hinge part can be attached to the door side and the fixed block can be attached to the frame side by roughly determining the position. . Also, at the hinge part, the tip part that extends parallel to the axis of one of the blades is bent to provide a locking part with a uniform cross section, and at the fixed part, while locking the locking part on the surface, Since the groove for sliding the blade is formed, the door can be moved up and down in the frame by inserting the locking part in the groove and sliding the blade on the fixed plate. The gap in the can be adjusted easily. Also, the engagement between the locking part and the groove makes it possible to adjust the lateral gap between the door and the frame by adjusting the opening angle between the fixed plate and the vane with the locking part as a fulcrum. it can. In this way, all gaps around the door can be adjusted.

Further, in the present invention, the hinge portion is only the one in which the tip portion of the conventional hinge is bent and the locking portion is provided, and the fixing plate forms the groove on the flat plate and the long hole is formed. Since it is only used, the structure of the hinge as a whole is simple, and thus it can be provided at a low cost. In addition, since the hinge part and the fixed plate are occluded over the entire tip part of the blade, there is little backlash between them, so that the hinge can be easily attached. The present invention provides such benefits.
