Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door mounting structure, and more particularly, to a door mounting structure suitable for improving the appearance of a hinge interposed between a door and a door frame.

[0002]

[Prior art]

 Generally, a hinge is used to attach the door to the door frame. This hinge is composed of a hinge pin and a pair of hinge members that are rotatably provided with the hinge pin as a fulcrum. Each hinge member is fixed to the door and the door frame, respectively. Then, the door is opened and closed.

First, an outline of a conventional structure will be described with reference to FIG. Here, FIG. 4 is a perspective view of essential parts showing an example of a pair of folding door mounting structures proposed in Japanese Utility Model Laid-Open No. 57-102674. In this figure, folding doors 50 and 51 are attached at two upper and lower positions via hinges 52 so that they can be expanded and folded. The hinge 52 includes a hinge pin 54 and a pair of hinge members 55 and 56 rotatably provided with the hinge pin 54 as a fulcrum. The hinge pin 54 is , A pair of upper and lower pin forming shafts (not shown). These pin forming shafts are integrated by a method such as press-fitting one shaft tip into a hole formed in the other shaft tip.

The hinge members 55 and 56 are respectively arranged along the longitudinal direction at the rectangular plate-shaped portions 55A and 56A and the end portions of the plate-shaped portions 55A and 56A which are opposed to each other by abutting the edges thereof. It is composed of a plurality of ring-shaped portions 55B and 56B which are arranged coaxially with each other at intervals. The one hinge member 55 is screwed and fixed to the end surface of the folding door 51 by a fixing screw 60, and the other hinge member 56 is folded by the fixing screw 60 via a part of the cushioning material 61. It is fixed to the end surface of the door 50, and by this, the folding doors 50 and 51 are attached so as to be openable and closable in the direction of relative rotation.

The cushioning material 61 includes a piece 61A extending along the vertical direction on the end surface of the folding door 50, and a mounting piece 61B having an outer shape corresponding to the plate-like portion 56A of the hinge member 56. The attachment piece 61B is fixed to the end face of the folding door 50 together with the hinge member 56. The cushioning material 61 is made of an appropriate elastic material such as rubber, and when the folding doors 50 and 51 are expanded in a horizontal row so that the hinge portions 55 and 56 are overlapped with each other, Direct contact between the plate-shaped portions 55A and 56A of the members 55 and 56 is avoided, and shock or noise is absorbed.

[0006]

[Problems to be solved by the device]

 However, the structure using the hinge 52 has the following problems. That is, from the state shown in FIG. 4, the folding doors 50 and 51 are expanded in the relative rotation direction so that the plate-like portion 55A and the mounting piece 61B are overlapped, that is, the folding doors 50 and 51 are moved horizontally. When the hinge pins 54 are arranged in a line, the outer peripheral side regions of the hinge pins 54 and the ring-shaped portions 55B and 56B through which the hinge pins 54 are inserted are exposed to the outside, and it can be said that the appearance is good. Absent.

Further, both of the hinge members 55 and 56 constituting the hinge 52 are only fixed by screwing directly to the respective end faces of the folding doors 51 and 50. In the state where 50 and 51 are folded as shown in FIG. 4, a large number of fixing screws 60 all appear in the external appearance, and this also poses a problem of impairing the appearance. These problems do not adequately meet the modern demand for the aesthetic appearance of individual building parts such as fittings to give residents even more luxury and satisfaction.

Further, when the folding doors 50 and 51 are expanded in a horizontal row, the hinge pins 54 and the ring-shaped portions 55B and 56B are prevented from protruding greatly from between the folding doors 50 and 51 toward the outside. In order to avoid this, arcuate portions 50A and 51A are formed at the corners of the folding doors 50 and 51, respectively, as regions for accommodating the hinge pins 54 and the like. Therefore, the folding doors 50 and 51 have to be specially formed with the arcuate portions 50A and 51A, which are relatively difficult to form, and there is a drawback that the folding doors 50 and the like are complicated.

The purpose of the present invention is to solve such a problem, and to reduce the exposed portion of the hinge between the door and the door frame to improve the appearance. It is to provide a door mounting structure that can be.

[0010]

It is attached to the frame 2 so as to be openable and closable.

The L-shaped short portion of the fixed end surface 1A is provided comparatively longer than that of the door-contact end surface 1B, and this short portion partially covers the outer peripheral side area of the hinge pin 10 described later. It is configured as a hinge hidden portion 1C that surrounds it. On the other hand, the pad 4 is fixed to the L-shaped short portion of the door contact end face 1B by means of adhesion or the like so that shock or noise when the door 1 is closed can be absorbed.

The door frame 2 has a plate thickness W2 which is thicker than the plate thickness W1 of the door 1, and in the present embodiment, the inside is formed hollow. As shown in FIGS. 2 and 3, the end face 2A of the door frame 2 is provided with a notch 6 formed in a substantially rectangular shape at the upper end thereof. The notch 6 is also formed at the lower end of the end face 2A of the door frame 2 in the same manner. Inside the notch 6, the hinge member holding member for connecting the door 1 via the hinge 3 is held. A part of the body 7 can be housed, and the hinge member holder 7 is fixed to the door frame 2 side by an appropriate bolt or adhesive while being housed in a predetermined position.

The hinge 3 includes a hinge pin 10 and a pair of hinge members 11 and 12 which are inserted through the hinge pin 10 and are rotatable relative to each other with the hinge pin 10 as a fulcrum. It is configured. Here, each hinge member is referred to as a built-in hinge 11 and a fixed hinge 12. As shown in FIG. 3, the hinge pin 10 is composed of a first pin forming shaft 10A and a second pin forming shaft 10B, and the first pin forming shaft 10A has a small diameter portion 10C on the lower end side in FIG. The pin forming shafts 10A and 10B are integrated by press-fitting the small diameter portion 10C into the hole 10D formed in the axial direction of the second pin forming shaft 10B.

The built-in hinge 11 has a plate-shaped portion 13 provided with a fixing screw hole 13 A at a substantially central portion, and one end side of the plate-shaped portion 13 at predetermined intervals in the vertical direction in FIG. It is composed of a plurality of ring-shaped portions 14. These ring-shaped portions 14 can be formed by providing pieces that partially project from the end of the plate-shaped portion 13 and winding these pieces in a closed loop shape.

Further, the fixed hinge 12 is provided in a shape having a short-sized portion 16 and a long-sized portion 17 which are bent so as to form a substantially L-shape when viewed from above. A plurality of ring-shaped portions 19 are provided at one end of the short-sized portion 16 at predetermined intervals so that they can be positioned on the same axis line without interfering with the ring-shaped portion 14. The ring-shaped portion 19 is formed in the same manner as the ring-shaped portion 14 of the built-in hinge 11. Further, the long portion 17 is provided with fixing screw holes 17A at two upper and lower positions in FIG. 3, and these fixing screw holes 17A can be fixed to the fixed end face 1A of the door 1 by using screws (not shown). ing.

In this embodiment, the plate-shaped portion 13 of the built-in hinge 11 is built in the hinge member holder 7 fixed to the door frame 2 side. This will be described in more detail. The hinge member holder 7 is integrally formed of a metal or a synthetic resin material, has a substantially hollow inside, and is formed into a substantially box-like shape. In the illustrated example, the hinge member holder 7 is shown to project larger than the end surface 2A of the door frame 2, but this is for the purpose of facilitating understanding of the invention, and actually projects a little. Not a thing.

The hinge member holder 7 is provided at a substantially central portion of one side wall 20 which is orthogonal to the insertion direction into the notch 6 formed in the end surface 2A of the door frame 2 and which extends along the vertical direction in FIG. An arcuate portion 22 that partially accommodates the outer periphery of the pin 10 and the ring-shaped portions 14 and 19 through which the pin 10 is inserted is formed. A vertical slit 23 is formed substantially in the center of the arc-shaped portion 22, and a partition wall 25 is formed along the slit 23 between the side wall 20 and the side wall 24 facing the side wall 20. ing.

As shown in FIG. 1, when the plate-shaped portion 13 of the built-in hinge 11 is built in the partition wall 25, the partition wall 25 is coaxial with the fixing screw hole 13 A of the plate-shaped portion 13. Is provided with a fixing screw hole 26. The partition wall 25 divides the internal space of the hinge member holder 7 into a first space 28 on the side opposite to the slit 23 and a second space 29 on the side of the slit 23.

A notch 32 is formed in a side wall 31 that forms a part of the first space 28 and is on the side of the door frame 2 that is inserted into the notch 6, and the notch 32 is formed. 32 acts as an insertion space for the fixing screw 33. On the other hand, as shown in FIG. 1, the partition wall 25 and the plate-shaped portion 13 are provided on the inner surface of the side wall 34 located on the opposite side of the side wall 31 and forming a part of the second space 29. The fixing screw holes 26 and 13A respectively formed and the fixing screw hole 35 located on the coaxial line are provided.

Next, a procedure for attaching the door 1 in this embodiment will be described. First, prior to mounting the door 1, the parts constituting the hinge 3 are assembled to complete the hinge 3 as a single body. At the time of this assembly, the ring-shaped portions 14 and 19 of the built-in member 11 and the fixed hinge 12 are coaxially positioned, and the first and second pin forming shafts 10A and 10B are provided inside the ring-shaped portions 14 and 19. The small diameter portion 10C of the first pin forming shaft 10A is press-fitted into the hole 10D of the second pin forming shaft 10B by inserting in the relative direction.

In this way, after the assembly of the hinge 3 is completed, the plate-shaped portion 13 of the built-in hinge 11 is inserted through the slit 23 of the hinge member holder 7, and the partition wall 25 and the plate-shaped portion 1 are inserted. The positions of the fixing screw holes 26 and 13A respectively provided in 3 are aligned. In this state, the fixing screw 33 is inserted through the notch 32 provided in the side wall 31, and the tip side of the fixing screw 33 is tightened and fixed in the fixing screw hole 35 of the side wall 34, whereby the built-in hinge 11 is formed. The plate-shaped portion 13 is embedded in the hinge member holder 7.

Next, with the side wall 31 of the hinge member holder 7 facing the notch 6 of the door frame 2, the hinge member holder 7 is inserted and fixed in the notch 6. At this time, although not shown, the hinge member holder 7 is firmly fixed in the notch 6 by using a fixing means such as an appropriate bolt. Then, the long portion 17 of the fixed hinge 12 left outside the hinge member holder 7 is brought into contact with the L-shaped fixed end surface 1A of the door 1, and in this state, the fixing screw hole 17A The fixed hinge 12 and the door 1 are connected with each other via screws, whereby the work of attaching the door 1 to the door frame 2 is completed.

Contrary to the above, after connecting the hinge 3 and the hinge member holder 7 to each other, the long portion 17 of the fixed hinge 12 is fixed to the fixed end surface 1A of the door 1. The work may be performed first, and then, the hinge member holder 7 may be fitted into the notch 6. When the door 1 thus mounted is closed, as shown in FIG. 1, the outer peripheral region of the hinge pin 10 holds the hinge hidden portion 1C provided on the fixed end face 1A of the door 1 and the hinge member holding member. The long part 17 of the fixed hinge 12 is separated from the plate-like part 13 built in the hinge member holder 7 at a predetermined distance from the side wall 34 to the door-contact surface. The fixed hinge 12 is separated from the side wall 34 integrally with the door 1 when opened.

Therefore, according to such an embodiment, the fixed end surface 1A of the door 1 is provided in an L shape, and the short portion of the L shape is used as the hinge concealed portion 1C to define the outer peripheral side region of the hinge pin 10. Since it is configured so that it is partially surrounded and hidden, it is possible to make the area difficult to see from the outside, and when compared to the conventional structure where the hinge pin is exposed to the outside, the exposed area of hinge 3 is Can be significantly reduced and the appearance can be further improved.

Further, a hinge member holder 7 provided separately is interposed in a mounting portion of the door 1 to the door frame 2, and the plate-shaped portion 13 constituting the hinge 11 built in the hinge member holder 7. Since the internal hinges are built in, it is possible to partially hide the components of hinge 3 and the heads such as bolts that secure internal hinge 11 to door frame 2 side are exposed to the outside. The effect is that there is no such thing. In this case, the hinge member holder 7 is partially exposed from the end surface 2A of the door frame 2, but the amount of protrusion from the end surface 2A is extremely small as described above, and the overall shape is Since it has a box shape, the door frame 2 has a morphologically fused appearance and does not spoil its appearance.

An arcuate portion 22 is provided on one side wall 20 of the hinge member holder 7, and the arcuate portion 22 can partially accommodate the outer peripheral portions of the hinge pin 10 and the ring-shaped portions 14, 19. In addition to the effect that the amount of protrusion of these parts can be reduced, it is not necessary to provide arcuate recesses in both the door 1 and the door frame 2, and the door 1 and the door frame 2 can be provided. Is also easy to form. Further, since the arcuate portion 22 is suitable for molding by a mold, it can be formed without difficulty, and it can be expected that the manufacturing cost can be suppressed by mass production.

Further, since the fixed hinge 12 has a shape including the short-sized portion 16 and the long-sized portion 17 so as to form a substantially L-shape, the built-in hinge built in the hinge member holder 7 is provided. It becomes possible to contact the outer surface side of the side wall 34 at a position spaced apart from the plate-shaped portion 13 of the number 11 by the formation of the arc-shaped portion 22, and it is effective that the hinge pin 10 and the like are largely projected outward. It can be avoided.

Further, since the door frame 2 is provided with the notch 6 and the hinge member holder 7 is fitted and housed in the notch 6, the hinge member holder 7 is attached to the door 1. If the work of fixing to the fixed end face 1A side of the above is preceded, it is extremely easy to position the door 1 with respect to the door frame 2 simply by fitting the hinge member holder 7 into the notch 6 in the subsequent work. Therefore, there is a special effect that one person can easily work. Such an effect is more remarkable especially when the door 1 is made of a material having a relatively heavy weight, for example, an iron door.

Next, variations of the above embodiment will be described. In the above-mentioned embodiment, the door mounting structure according to the invention according to claim 2 was described, but the fixed hinge 12 projects almost at a right angle to the built-in hinge 11 when the door is closed. Alternatively, it may be fixed to the hinge hidden portion 1C of the door. In addition, when fixing the hinge member holder 7 to the door frame 2 side, the example in which the notches 6 are formed at the upper end and the lower end of the end face 2A of the door frame 2 is shown and described, but the present invention is not limited to this. However, it is of course possible to provide the notch 6 at a position where the vertical interval between the notches 6 is shortened.

Further, the hinge member holder 7 may have various internal design changes as long as the plate-shaped portion 13 of the built-in hinge 11 can be built therein. Further, the hinge member holder 7 is not limited to being provided on the door frame 2 side, but it is conceivable to fix the hinge member holder 7 to the door 1 side, for example. In this case, it is possible to cope with this by forming an appropriate cutout or the like of the hinge member holder 7 on the door 1 side and forming a concealing member on the corresponding portion of the end surface 2A of the door frame 2 while forming an appropriate cutout or the like.
