Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is used by being attached to a rotating base of a door, a door, etc. to be opened and closed, and a gap between a door frame and a door can be minimized. The present invention relates to a hinge having the features of.

(Prior Art) As a general hinge that has been widely used,
As shown in the figure, one end of each is bent in a tubular shape to form the upper and lower pipe parts.
The upper and lower blades 23, 24 provided with 21, 22 are rotatably held by inserting the shaft rod 26 into the two pipe portions 21, 22 holding the washer 25 and at the same time, The squeeze 27 is press-fitted so that the shaft rod 26 does not fall out at the upper and lower open ends. 28 is above
A screw hole, 29, which is used to fix the lower blade plates 23, 24 to the object, is a hinge.

(Problems to be solved by the invention) Conventionally, in order to attach a door or the like to the door frame with the hinge 29, one of the vane plates 23 and 24 is completely attached to the place where the hinge 29 such as the door frame and the door is attached. It was done by providing a recess that can be filled in. As a result, the door and the like were relatively closely attached to the door frame, and there was almost no gap between them.

However, recently, in order to improve work efficiency and the like, a method has been adopted in which the hinge 29 is directly attached to the door frame, the door or the like without providing the recess. Therefore, due to the thickness of the upper and lower blades 23, 24, there will be a gap between them.
The appearance is unsightly, so there is a strong demand for improvements.

Also, when attaching hinges 29 directly to the door frame and door, make sure that the hinge mounting surface of the door frame sees the axis of the hinge as the inside and does not form a right angle with the outside surface of the frame. If you do not, even if you try to close the door with the hinge attached, the angle of the door frame hinge attachment surface will interfere and it will not fit inside the door frame. Therefore, it is done to remove the attached lower blade plate 24 and scrape the mounting surface to make it perpendicular to the outer surface of the door frame, and then mount the door again, but this work is troublesome and time-consuming. Therefore, the appearance of a hinge corresponding to this was strongly desired.

In addition, since the hinge 29 is right-handed in use and cannot be used left-handed, it is necessary to prepare another hinge when left-handed, which is extremely inconvenient for consumers. Also, it will be an economical burden.

If hinge 29 is used for a long time, lower spill 27 may come off and shaft rod 26 may fall off, resulting in an accident that damages hinge 29 and the door. On the other hand, various measures have been taken, which causes an unexpected manufacturing cost, which also contributes to the cost increase of the hinge.

(Means for Solving the Problem) The present invention has been made by paying attention to such a problem in the related art, and reduces the thickness of both blade numbers within a range having a required mechanical strength. At the same time, the object of the present invention is to solve the above-mentioned problems by changing the relational position between the two and further improving the relationship between the shaft rods to remarkably enhance the performance of the hinge.

According to the present invention, with respect to the upper tube portion 2 formed at one end of a thin plate-shaped member, the extended back surface passes through the axis of the upper tube portion 2,
With respect to the upper blade plate 1 provided with the upper plate body 3 having the screw hole 4 chamfered with a diameter more than double the hole diameter, and the lower pipe portion 6 formed at one end of a similar plate-shaped member, An inner peripheral wall is provided between the lower blade plate 5 and a lower plate body 7 having a screw hole 4 and a similar screw hole 8 so that the surface on the center line in the vertical direction passes through the axis of the lower pipe portion 6. A ring 11 having a recess 13 opened upward in 12 is sandwiched between the upper and lower pipe parts 2 and 6, and a projection 10 provided at a predetermined position is fitted into the recess 13 so that the upper and lower pipe parts 2・ 6
Further, the hinge is formed by inserting the shaft rod 9 into the ring 11 and crimping the lower end of the shaft rod 9.

(Function) When the hinge is used, the upper and lower blades are arranged so that the back surface of the lower plate body is aligned with the surface passing through the center of the upper plate body in the thickness direction. There is a clearance between the hinge and the upper plate body, and even if the angle formed by the hinge mounting surface of the door frame and the outer surface of the frame is slightly acute, the hinge will be closed when the door is closed. The strain force applied to is absorbed by the clearance, and because it is made of a thin plate-shaped member,
The gap between the door frame and the door is very small.

Further, the hinge can be used as a left-handed one by using a right-handed one by using the upper vane plate upside down and fitting it on the shaft rod, and thus has a dual-purpose function.

Further, in the hinge, since the projection of the shaft rod is fitted into the recess of the ring, the shaft rod does not drop out even if it has been used for many years, and the accident caused thereby can be reliably prevented. Furthermore, since the lower end of the shaft rod is crimped and fixed to the lower pipe part, the shaft rod will not come off and hinder the work when the upper blade is lifted during the attachment work. .

Further, since the hinge does not use the conventional shavings at the open ends of both pipe parts, the hinge can be easily assembled, and the number of work steps can be reduced and the cost can be reduced.

(Embodiment) The present invention will be described in detail below based on an embodiment shown in FIGS. 1 to 4. Reference numeral 1 denotes an upper tube portion 2 formed by bending one end of a thin rectangular plate-shaped member (about 1.7 mm) into a tubular shape, and an extension surface of the rear surface passing through the axis of the upper tube portion 2. And a plurality of screw holes 4 formed by chamfering with a dish diameter larger than twice the hole diameter only on the surface side at a required portion of the upper plate body 3 (see FIG. 4). It is provided).

Reference numeral 5 denotes a lower tube portion 6 formed by bending one end of a rectangular plate-shaped member having the same thickness as the upper blade 1 into a tubular shape having the same diameter as the upper tube portion 2 and a surface passing through a center line in the thickness direction. A lower blade plate composed of a lower plate body 7 arranged so as to pass through the axis of the pipe portion 6,
A plurality of screw holes 8 (four in the drawing) are chamfered with a dish diameter larger than twice the hole diameter at the required positions.

Reference numeral 9 denotes a shaft rod which is provided with a projection 10 near the center by cutting, and which is inserted into the upper and lower pipe portions 2 and 6 to hold the upper and lower blade plates 1 and 5, and 11 is an inner peripheral wall 12 of the shaft rod 9. It is a short cylindrical ring provided with an upwardly opening recess 13 into which the protrusion 10 is fitted.

The hinge 14 is formed by stacking the ring 11 on the upper end of the lower pipe portion 6 of the lower blade plate 5, inserting the shaft rod 9 into the ring 11 and the lower pipe portion 6, and inserting the projection 10 into the recess 13 that opens upward. After fitting the upper pipe portion 2 of the upper blade 1 to the upper portion of the shaft rod 9, the lower end protruding from the lower pipe portion 6 of the shaft rod 9 is caulked 15 to move the shaft rod 9 to the lower pipe portion 6. It was fixed and assembled to.

This hinge 14 is similar to a conventional hinge, in which the lower blade plate 5 is used as a door frame, the upper blade plate 1 is used as a door, and the respective screw holes 4,
It is used by fixing with a screw through 8.

In this case, when the hinge 14 is used, the upper and lower blade plates 1 and 5 are arranged so that the back surface of the lower plate body 7 is aligned with the center plane passing through the center of the upper plate body 3 in the thickness direction. Therefore, the mounting surface of the door frame is slightly acute with respect to the outer surface of the frame, and even if the lower plate body 7 is also mounted at that angle, the clearance between the lower plate body 7 and the upper plate body 3 is increased. Then, the door attached to the upper plate body 3 is installed in a normal state without being slanted. Moreover, since the upper and lower plate bodies 3 and 7 are thin, the upper and lower plate bodies 3 and 7 are Even if the thickness is shifted by half, the gap between the door frame and the door becomes very small (about 2.55 mm or less), which is smaller than the conventional hinge (gap is about 3 mm or more). You can attach the door to the door frame with.

Also, the hinge 14 is right-handed in use as shown, but if the shaft 9 is fitted with the top blade plate 1 turned upside down, it becomes left-handed in use, and the right-handed one is left. It can also be used without permission and has a dual-purpose function.

Further, the hinge 14 has the projection 10 of the shaft rod 9 fitted into the recess 13 opening upward of the ring 11, so that the shaft rod 9 does not fall off even if it has been used for a long time, which is caused by it. Accidents can be reliably prevented. Further, since the lower end of the shaft rod 9 is fixed to the lower pipe portion 6 by crimping 15, when the upper blade plate 1 is lifted during the attachment work, the shaft rod 9 may come off and hinder the work. Does not happen.

Moreover, since the hinge 14 does not use the conventional shavings at the open ends of both the pipe portions 2 and 6, it is easy to assemble, and the number of work steps can be reduced and the cost can be reduced.

In the above embodiment, the hinge 14 is the upper / lower plate body 3,
Since the thickness of 7 is thin, both screw holes 4 and 8 are formed by chamfering with a dish diameter larger than twice the hole diameter, and the screw 16 to be used is the existing one as shown in FIG. By making the diameter of the head 17 more than twice the diameter of the screw shaft 18 and reducing the buildup at the base of the screw shaft 18 to make the thickness of the head 17 thinner by making the shape of the head 17 different from that of the screw shaft 18. , Upper and lower blades 1, 5
When the screws are attached by means of screws 16, the necessary attachment strength is maintained, and the head 17 does not protrude from the surface of the upper and lower blades 1, 5.

(Effects of the Invention) Since the present invention has the above-described configuration, the following effects are obtained.

(1) Even if the mounting surface of the door frame is at an acute angle to the outer surface of the same frame by changing the arrangement of the upper and lower blades,
Does not interfere with opening and closing the door.

(2) Since the upper and lower plate bodies are made thin, the appearance can be improved by reducing the gap between the door frames even if the arrangement is changed.

(3) Convenient in construction because it has a function that can be used for both left and right hand.

(4) It is possible to reliably prevent the shaft rod from falling out or coming out during use, and prevent an accident from occurring.

(5) Since Kiboshi is not used at all, the number of man-hours associated with it can be reduced.
