Description

Hinge structure of folding door

technical field

The invention relates to a hinge part structure of a folding door. The door connected with the hinge part can be bent evenly without impacting sound when folding, and fingers will not be caught by the hinge part when opening and closing the folding door.

Background technique

Fig. 9 shows the opening and closing action of an existing general folding door, which is composed of a main door (a) and an auxiliary door (b), and joints such as hinges are provided therebetween so that they can be folded mutually. Moreover, the auxiliary door (b) is rotatably installed on the shaft (c) on one side of the door pivot, and the slider arranged on the upper end of the main door (a) can move along the upper guide rail, so it can move along the The trace switch shown in the figure.

The folding door installed at the entrance and exit is easier to open and close than the single door. Especially when the entrance and exit are wide, if a single door is installed, when the handle at the front end of the single door is held to open and close, the turning radius centered on the shaft on the side of the door pivot becomes larger, making the operation difficult, and the front end will be far away. well beyond the channel side. In contrast, if it is a folding door, since it moves along the upper guide rail as shown in Figure 9, the operation is relatively simple.

However, the main door (a) and the auxiliary door (b) of this folding door are hinged so that they can be folded, and the switch operation is carried out by holding the handle (d) installed at the front end of the main door (a). At this time, as shown in the figure, the hinge part of the folded folding door has an opening, and the opening (f) is closed by closing the folding door, but the opening (f) sometimes catches fingers due to the closure. . Clothes worn on the body and objects held can also be caught.

In this way, although the hinge part is opened due to the folding of the folding door, when such a hinge part structure is adopted, the external appearance of the room sandwiching the folding door does not have the same appearance. Moreover, when the folding door is folded, the side ends of the main door (a) and the auxiliary door (b) are exposed from the opening, and the trim and mounting screws are exposed on the surface. In addition, in the case of the hinge shown in the figure, after the folding door is aligned and closed, a slight gap is generated between the main door (a) and the auxiliary door (b), and light passes through.

The "hinge for folding doors" of Japanese Patent No. 3240508 eliminates the gap generated between the main door (a) and the auxiliary door (b), and prevents fingers or clothes from being caught by the hinge when opening and closing the folding door Work hard. That is, "the structure is as follows: a pair of perforated plate members are installed on the corresponding side end faces of the two door panels; hinge fittings are arranged at respective two ends of the above-mentioned perforated plate members; 1. A hinge part that connects the perforated plate members with the help of the above-mentioned hinge fittings so that they can rotate relatively freely; The inclined surface on the side of the surface forms a V-shaped space that opens toward the interior side.”

However, the above-mentioned "hinge for a folding door" forms a V-shaped space that opens toward the indoor side when the folding door is formed in a straight line, and this space detracts from the appearance of the hinge portion of the folding door. That is, when the switch is operated, although the phenomenon of pinching fingers is eliminated, the existence of this space detracts from the appearance of the folding door. Due to this space, the outer and inner hinges of the folding door have different appearances.

Although the folding door shown in Figure 9 uses a hinge as the hinge (e) connecting the main door (a) and the auxiliary door (b), as shown in Figure 10, most of them use the joint part (i). The joint part (i) is provided with shaft holes (g), (g) at the side ends of the main door (a) and the auxiliary door (b), and the two shafts (h) embedded in the two shaft holes (g), (g) ) stand up. Although side end parts (j), (j) are attached to the side ends of the main door (a) and the auxiliary door (b), shaft holes (g), (g) It is relatively simple to insert and connect the shafts (h) and (h) erected on the joint part (i) into the shaft hole (g).

However, in this hinge structure, the main door (a) and the auxiliary door (b) connected by the joint member (i) cannot be bent uniformly, so it is difficult to smoothly open and close the folding door. That is, since the center of rotation is biased towards one of the two shafts (h) and (h) erected on the joint member (i), it is difficult to perform switching operations accompanied by a uniform bending movement around the joint member (i) .

Contents of the invention

Thus, the hinge portion of the conventional folding door has the above-mentioned problems. The problems to be solved by the present invention are precisely these problems. The present invention provides a hinge part structure of a folding door, which will not pinch fingers or clothes when the folding door is opened and closed. went well.

The hinge part structure of the folding door of the present invention is made to install the side end part that is roughly U-shaped cross-section at the side ends of the main door and the auxiliary door, and the upper and lower ends of the hinge formed at the front end of one arm of the side end part are connected by a joint part. up structure. There is a shaft hole on the hinge, and the two plug shafts erected and extended from the joint part are inserted into the shaft hole to connect the two hinges. Therefore, the main door and the auxiliary door can be rotated and folded around the shaft of the joint part. .

A hole other than the above-mentioned shaft is formed on the joint member through which a screw is passed to mount the hinge cover. A hinge cover having the same length as the side end parts and inserted between the upper and lower joint parts can block the gap (space) generated between the hinges formed on the two side end parts. In addition, by forming a trim cover at the end of the other arm of the side end member and making the trim cover similar in shape to the surface side of the hinge, the appearance of both sides of the hinge can be substantially the same.

The folding door is composed of the above-mentioned main door and an auxiliary door, which are connected by a hinge so that they can be folded, and the door pivot side of the auxiliary door is rotatably supported. Also, a slide block is installed on the upper guide rail to suspend the main door, and the slide block moves along the upper guide rail. The basic structure of this folding door is the same as the existing one, and there is also a semi-automatic structure in which the spring is contained in the hinge of the auxiliary door rotatably supported by the shaft. That is, a folding door that is opened by hand can be closed independently, and a folding door that is closed by hand can be automatically opened conversely.

On the other hand, the hinge portion structure of the present invention is such that the bending angles of the main door and the auxiliary door are uniform when opening and closing the folding door. Therefore, a main gear is installed concentrically with the shaft extending from the joint member, and an auxiliary gear is provided that meshes with the main gear. The two main gears are not in contact with each other, but the auxiliary gears mesh with each other, which can make the bending angle of the main door and the auxiliary door uniform. In addition, although the bending angles of the main door and the auxiliary door can be made uniform by meshing the main gears, in this case, the outer diameter of the main gear becomes large to protrude from the door surface.

Therefore, the present invention employs a structure in which the outer diameter of the main gear is made so small that it does not protrude from the door surface while using the auxiliary gear. Here, the shaft inserted into the hinge shaft hole of the door side end member does not necessarily have to be mounted on the joint member, and the shaft provided on another member may be inserted into the hole of the joint member while being inserted into the side end member. in the hinge shaft hole.

Detailed ways

Embodiments of the present invention will be described in detail below with reference to the drawings.

Example

Figure 1(a) and Figure 1(b) show the situation where the folding door is stretched and the entrance and exit are closed, Figure 1(a) is a front view, showing the surface seen from the inside of the folding door, and Figure 1(b) is a rear view , Indicates the surface seen from the outside of the folding door. In the figure, 1 indicates a main door, and 2 indicates an auxiliary door, and the main door 1 and the auxiliary door 2 are foldably connected by a hinge portion 3 . And, one side of the door pivot of auxiliary door 2 supports the shaft with hinge 4 so that the auxiliary door 2 can rotate, and the upper guide rail 5 of the main door 1 is slidably fitted and suspended on the slide block 6 that slides. Move together with slide block 6, make this folding door fold up.

Above-mentioned slide block 6 is installed on the front end of main door 1, and, because the width dimension of this main door 1 and auxiliary door 2 is substantially equal, so, the main door 1 and auxiliary door 2 of folded folding door overlap, main door 1 The front end portion will not exceed a lot from the upper guide rail 5 to one side of the channel.

However, although a handle 7 and a latch 8 are installed inside the main door 1 , they are located not at the front end but on the side of the hinge with the auxiliary door 2 . Here, the styles of the handle 7 and the latch 8 are not limited, but as shown in FIG. 2 , a U-shaped handle is easy to hold and easy to open and close the folding door. In addition, the latch 8 is installed on the lower side of the handle 7, and the latch rod can be protruded upwards and inserted into the guide groove of the upper guide rail 5 by rotating the latch 8.

Fig. 3 shows a cross-sectional view of the folding door device provided with the hinge structure of the present invention, in a folded state and an extended state. However, when folding the unfolded folding door, if the vicinity of the hinge portion is pushed from the outside to make it folded into a substantially V shape, then the front end of the main door 1 is completely closed by pushing the front end of the main door 1 along the upper guide rail toward the side of the auxiliary door. When folded, the main door 1 and the auxiliary door 2 overlap each other after being folded.

The front end of the main door of the overlapping and folded folding door will not go beyond the channel side from the upper guide rail. Since the slider 6 is mounted on the upper end of the front end of the main door 1, the slider 6 only slightly exceeds the front end. Conversely, when stretching the folded folding door, hold the handle 7 installed on the main door 1 and pull it to the front.

Then, when it is stretched to a certain extent to form a substantially V shape, if the handle 7 is pushed, the folding door is fully unfolded and the entrance and exit are closed. When locking the closed folding door, the above-mentioned latch 8 is rotated so that the latch rod protrudes upward and is inserted into the guide groove of the upper guide rail 5 .

Since the handle 7 is installed on the hinge part side of the main door 1, the folding door can be completely closed if the handle 7 is held and pulled firmly, and then the handle 7 is held and pushed as it is. Although the handle 7 moves in the direction of the arrow shown in the figure, the moving distance is small, and even a disabled person in a wheelchair can operate without moving the place.

Also, when folding the extended and closed folding door on the inside, you only need to hold the handle 7 and pull it to the front. direction to move, but the moving distance is also small, and the wheelchair does not have to move.

On the contrary, if the handle is installed at the front end of the main door 1 as before, even if the handle is pulled firmly along the upper guide rail, although the folding door is stretched to a certain extent, it cannot be fully extended to be closed. Therefore, when stretched to a certain extent to form a substantially V-shape, it cannot be closed without moving the wheelchair and pressing the joint portion.

However, the present invention relates to the hinge portion structure of the folding door, and the position of the handle 7 is free and unrestricted, and it can also be installed on the front end portion of the main door 1 . Also, the position of the latch 8 is not particularly limited, but it is preferably located on the hinge side for easy switch operation, so that even a disabled person in a wheelchair can easily operate without moving the wheelchair.

Here, what is shown in FIG. 4(a) and 4(b) is the concrete example which shows the structure of the hinge part of this invention. The main door 1 and the auxiliary door 2 are connected by the hinge part 3 so that they can be folded. Figure 4(a) shows the situation where the main door 1 and the auxiliary door 2 are stretched in a straight line, and Figure 4(b) shows the main door 1 and the auxiliary door 2 The case where they are overlapped and folded. The side end parts 9, 9, which are roughly U-shaped cross-sections, are fixed on the side ends of the main door 1 and the auxiliary door 2. For this reason, recesses are formed at the side ends of the doors, and the side end parts 9, 9 cooperate with the recesses. Install.

In addition, a trim cover 11 is formed at the tip of one arm 10a of the side end member 9 having a substantially U-shaped cross section, and a hinge 12 is formed at the tip of the other arm 10b. In addition, the shaft hole 13 penetrates the hinge portion 12 . Here, the outer surface 14 of the above-mentioned trim cover 11 and the outer surface 15 of the hinge 12 are all made into smooth arc surfaces, and the curvature of the arcs is almost the same. Therefore, the outer appearance of the hinge portion seen from the surface and the inside has almost the same shape.

The shaft erected from the joint part is inserted into the shaft holes 13, 13 of the above-mentioned hinge, and the hinges of the main door 1 and the auxiliary door 2 are connected by the joint part, and each hinge can rotate around the shaft. 16 of this figure represents a hinge cover, which is made with the same length as the side end parts 9, 9 that are screwed to the side ends of the main door 1 and the auxiliary door 2, and can cover the gap (space) that occurs between the two hinges. That is, the above-mentioned hinge cover 16 is screw-fixed to the joint member arranged at the lower end of the hinge and the joint member arranged at the upper end of the hinge.

5(a) and 5(b) show an embodiment of the hinge structure of the present invention. Fix the brackets 17 and 17 for fixing the gears to the upper ends of the main door 1 and the auxiliary door 2 while extending to the side of the hinge, and install the main gears 18 and 18 on the brackets 17 for fixing the gears. , 17 front ends. 8 (a) and 8 (b), as the bracket 17 for fixing the gear shown separately, its shape is bent into a roughly 'V' shape, and while the main gear 18 is installed at its front end, it is made to be in line with the main gear. A concentric shaft 19 extends from the gear 18 . Here, the main gear 18 is fixed on the bracket 17 for fixing the gear without rotation.

20 in this figure represents a joint member, which is arranged on the upper ends of the hinges 12, 12 shown in Fig. 4(a) and Fig. 4(b) and fixed with screws. 7 (a) and 7 (b), as shown in Figure 7 (a) and 7 (b), the joint part 20 is made into an approximately elliptical shape, and two shafts 21, 21 are erected symmetrically around the central axis M-M. Similarly, the holes 22, 22 are symmetrical and run through the joint. Part 20. Further, auxiliary gears 23, 23 are attached to the shafts 21, 21, and the auxiliary gears 23, 23 can mesh with the main gear 18 fixed to the brackets 17, 17 for fixing the gears. Moreover, the auxiliary gears 23, 23 mesh with each other.

Here, since the main gears 18, 18 do not mesh with each other, their diameter is smaller and they do not arch out from the door surface. When the main door 1 and the auxiliary door 2 are folded as shown in FIG. The center is bent and folded at the same angle.

Although Fig. 5 (a) and 5 (b) are the hinge part structure that constitutes at the upper end of hinge 12, 12, also can constitute the hinge part of similar structure at the lower end. However, this hinge portion structure may be configured so that only the joint member 20 is attached only to the upper end, or to the lower end. But in this case, since the auxiliary gears 23, 23 are not required, the shafts 21, 21 are not required, but the joint part 20 for erecting the shafts 21, 21 can still be used naturally. In addition, since the bracket 17 for fixing the gear is not used, the shafts 19, 19 may be fixed and erected on the joint member 20 instead of the holes 22, 22, thereby fixing the joint member 20 to the hinge cover 16 with screws.

In this way, the joint members 20, 20 are disposed on the upper and lower ends of the hinges 12, 12, and are fixed to the upper and lower ends of the hinge cover 16 for covering the hinges 12, 12 with screws. In this hinge cover 16, screw holes 24, 24... are formed at 5 places as shown in FIGS. 4(a) and 4(b). In this way, the screws passing through the holes 25, 25... of the joint member 20 are screwed to the threaded holes 24, 24...

As mentioned above, the hinge structure of the folding door of the present invention is that the side end parts are installed on the end faces of the main door and the auxiliary door, and at the same time, the hinge of the side end parts is connected by the shaft extending from the joint part, and the main gear and the auxiliary door are installed at the same time. gear, so that the following effects can be obtained.

The hinge structure of the folding door of the present invention is that side end parts are installed at the side ends of the main door and the auxiliary door, and the hinges of the two side end parts are connected by a shaft extending from the joint part so as to be foldable. In addition, since the hinge cover is installed between the two hinges by using the upper and lower joint members, it is possible to prevent a gap between the hinges. In addition, since the hinge cover is provided, fingers or clothing will not be caught when opening and closing the folding door.

And, by making the hinge provided at the front end of one arm of the side end part and the outer surface shape of the rim cover provided at the front end of the other arm the same, the hinge part of the folding door is basically the same on the outside and inside, and the appearance of the hinge part is improved. . Furthermore, in the present invention, a main gear concentric with the shaft inserted into the shaft hole of the hinge shaft is provided, and an auxiliary gear meshed with the main gear is provided, and the two auxiliary gears mesh with each other. Therefore, the main door and the auxiliary door are folded at the same angle around the hinge portion, and it is possible to prevent a knocking sound during the folding operation. Also, since the main gears do not mesh with each other and the auxiliary gears mesh with each other, the outer diameter of the main gear becomes small and does not protrude from the door surface.
