Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a reinforcing structure for a door hinge that attaches a door to a vertical frame.

0002

[Conventional technology]

The left and right leaves of the door hinge should be aligned against the edge of the door and the surface of the vertical frame, respectively. It is necessary to securely fix the product so that it can withstand the shearing force and peeling force caused by the load. For this reason, recesses are formed on the edge of the door and on the surface of the vertical frame to fit the leaves into. Each leaf is fitted into the recess and secured with screws. However, the surface of a vertical frame made of wood can be easily scraped to form dents. However, vertical frames made by metal extrusion or bending cannot have leaves. It is difficult to form a dent on the surface of the plate to be fixed according to the shape of the leaf. For this reason, the current situation is that leaf fixation relies solely on the tightening force of screws.

0003

[Problem that the idea aims to solve]

Therefore, when fixing the leaf to the plate of the vertical frame using only screws, it is necessary to The number of screws used was large, making screw tightening work extremely troublesome. Therefore, the present invention reduces the number of screws used to fix the leaf to the plate of the vertical frame. The technical challenge was to be able to securely fix the leaf to the plate of the vertical frame. It is said that

0004

[Means to solve the problem]

In order to solve the above problems, the present invention has one leaf fixed to the edge of the door. A door knife whose other leaf is fixed with screws to the plate of the vertical frame to which the door is attached. In the reinforcement structure of No. 1, the screw hole for the screw that fixes the leaf to the plate part of the vertical frame is shaped. In the nut plate that has been formed, insert a hole on the back side of the plate into the through hole drilled in the plate. Insert the leaf that is fitted into the plate and fixed to the surface of the plate from the sliding direction. A feature is that a holding protrusion is formed.

[0005]

[Effect]

According to the present invention, first, the back side of the plate is inserted into the through hole drilled in the plate of the vertical frame. Insert the protrusion of the nut plate into the protrusion and fix it to the surface of the plate of the vertical frame. Insert the leaf of the door hinge from the direction opposite to the nut plate. Next, screw the screw that fixes the leaf into the screw hole of the nut plate, and then Tighten the leaf to the plate of the vertical frame using screws and nut plates.

[0006] As a result, the leaf is not only screwed to the plate of the vertical frame, but also It is held and fixed by the protrusion of the nut plate fitted into the through hole drilled in the There is. Therefore, the nut plate protrusions bear the force that is applied to the leaf. The number of buses used can be reduced.

【Example】

Embodiments of the present invention will be specifically described below with reference to the drawings. Fig. 1 is a perspective view showing the first embodiment of the invention, Fig. 2 is a plan view thereof, and Fig. 3 is a perspective view showing the first embodiment of the invention. It is a perspective view showing a second example.

[0008] The door hinge 1 of the first embodiment shown in FIGS. 1 and 2 is a hinge fixed to the end of the door. Lift up the other leaf 2 together with the door, and that leaf 2 will attach to the door. The shaft pin 6 fixed to the other leaf 3 fixed to the plate part 5 of the frame 4 is removed. It has a removable flag hinge.

[0009] The leaf 3 has two upper and lower screw holes 8, 8 formed on the knuckle 7 side to which the shaft pin 6 is fixed. The screws 9 inserted into the respective screw holes 8, 8 are inserted between the plate portion 5 of the vertical frame 4. A female screw thread formed on the nut plate 10 arranged on the back side of the plate part 5 It is designed to be screwed into the holes 11 and 11 and fixed to the plate part 5 of the vertical frame 4 with screws. Ru.

0010 On the other hand, the nut plate 10 has a through hole 12 formed in the plate portion 5 of the vertical frame 4. The leaf 3 is fitted from the back side of the plate part 5 and fixed to the surface of the plate part 5. A tongue-shaped protrusion 13 is formed to be inserted and held from the sliding direction. This projecting piece 13 is a lead that overlaps the nut plate 10 from the sliding direction. It is inserted into the slot 14 formed at the tip of the leaf 3 to absorb the shearing force applied to the leaf 3. At the same time as supporting the leaf 3, the tongue portion 15 slides into contact with the surface of the leaf 3 so as to press it. The peeling force applied to the leaf 3 is supported.

[0011] Therefore, when fixing the leaf 3 of the door hinge 1 to the plate part 5 of the vertical frame 4, First, insert the protrusion of the nut plate 10 into the through hole 12 formed in the plate portion 5 from the back side. The piece 13 is fitted and the protruding piece 13 is made to protrude to the surface side of the plate portion 5.

0012 Next, the protrusion 13 is inserted into the slot 14 formed in the leaf 3 of the door hinge 1. The leaf 3 is attached to the nut plate along the surface of the plate portion 5 of the vertical frame 4. 10 and the nut plate 10 from the sliding direction.

[0013] As a result, the leaf 3 is inserted into the protrusion 13 of the nut plate 10 and It is held by the protruding piece 13 of.

[0014] In this state, insert the screws 9 into the screw holes 8 and 8 of the leaf 3, respectively, and into the screw holes 11, 11 of the nut plate 10.

[0015] In this way, the leaf 3 is screwed to the plate portion 5 of the vertical frame 4, and It is held by the protruding piece 13 of the nut plate 10 and securely fixed to the plate part 5. Now, the number of screws used, which previously required five, can be reduced to just two. This greatly reduces the labor required for the troublesome screw fixing work.

[0016] Next, in the second embodiment shown in FIG. Fit the hook-shaped protrusions 16, 16 into the through holes 17 bored in the plate portion 5 of the vertical frame 4. Insert both upper and lower ends of the leaf 3 into the protrusions 16 and 16 to hold it. It has become. In this case, it is not necessary to form the slots 14 in the leaves 3 as in the first embodiment. Therefore, ready-made door hinges can be used as they are. In addition, each of the above embodiments shows a reinforcement structure for a flag hinge with two knuckles. However, the present invention can of course be applied to three-pipe hinges, five-pipe hinges, etc.

[0017]

[Effect of the idea]

As described above, according to the present invention, the leaf of the door hinge is fixed to the vertical frame of the door. Reduce the number of screws used for fixing the screws and save labor when tightening the screws. It has the excellent effect of being able to
