DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge unit provided with a hinge and a hinge interposed between the fixed body and the opening / closing body or between the opening / closing bodies to smoothly open and close the opening / closing body, and the hinge unit. Door system.

[0002]

2. Description of the Related Art Heretofore, hinges have been used frequently everywhere, such as hinged doors and folding doors, in which an opening and closing body can be freely opened and closed on another opening or closing body or a fixed body.

One of the most common hinges is a hinge 100 having a one-point fulcrum structure as shown in FIG. The hinge 100 is a combination of two mounting plates 100b and 100c rotatably (rotatably) with respect to one common shaft 100a. The two mounting plates 100b and 100c are, for example, a folding door 101. Two panel bodies 101a and 101b to be formed
Attached to opposite sides of the As a result, the panel bodies 101a and 101b are bent around the fixed shaft 102 in a bellows shape as shown by the solid line and the imaginary line, and the slide shaft 1 is moved.
Numeral 03 slides in a rail body (not shown) and can be opened and closed freely.

As a modification of the one-point fulcrum structure, a hinge 110 having a two-point fulcrum structure shown in FIG. 13 is also known. This hinge 110 is attached to the entire side surface of the panel bodies 111a and 111b in the vertical direction, that is, a so-called "overall hinge".
(Also called "through hinge"). The hinge 110 includes two shafts 110a and 110b that individually rotate the panels 111a and 111b, and the two shafts 110
mounting plates 110c and 110 that rotate about the a and 110b
d and the connecting member 1 connecting the two shafts 110a and 110b.
10e. As a result, when the folding door 111 is opened,
The panel bodies 111a, 111 are changed from the solid line illustration to the virtual line illustration.
11b rotates while folding in a bellows shape.

FIG. 14 shows an example of another type of hinge.
Shown in The hinge 120 also has the structure of the entire hinge, and has two fulcrums. This hinge 120 is a panel body 1
A pair of mounting plates 120a, 120b attached to the mounting plates 21a, 121b and having one end curved;
a, 120b for rotatably connecting the first and second members 120a, 120b. Gears are formed inside and outside the curved portions of each of the mounting plates 120a and 120b, and the mounting plates 120a and 120b are meshed with each other by their outer gears. The connecting body 120c has a concave cross section in the transverse direction as shown in the figure, and cylindrical portions 1201 and 1202 are integrally formed inside the two protruding ends. A gear is formed on the circumference of each of the cylindrical portions 1201 and 1202, and the inner gear of the curved portion of the mounting plate 120a (120b) meshes with this gear. As a result, the panel bodies 121a and 121b can be pivoted around the two cylindrical portions 1201 and 1202, respectively, as shown by the solid line (folded door open state) and the virtual line (folded door closed state) to open and close the folding door. Can be.

[0006]

However, the above-mentioned conventional hinge has the following disadvantages.

Although the hinge 100 having a one-point fulcrum shown in FIG. 12 has a simple structure, the gap W1 between the panel bodies 101a and 101b when the door is opened, that is, a dead space is relatively large as shown by the imaginary line in the figure. In addition, when the folding door is closed from the state of the imaginary line to the state of the solid line in FIG.
There is a concern that a finger may be pinched in the gap P between the members 1b, especially in a child or the like. The corners of the panel bodies 101a and 101b can be formed in a tapered shape or a cover can be provided so as not to pinch a finger, but this causes problems in manufacturing cost and appearance.

Further, a hinge 110 having two fulcrums shown in FIG.
In particular, as shown by the phantom line, the connecting body 11 of the hinge 110
Due to the existence of 0e, there is a problem that the dead space W2 when the panel bodies 111a and 111b are folded is very large. This problem is the same as in FIG.

An unsolved problem common to the structures of FIGS. 12 to 14 is the problem of the center of rotation of the door. This problem is particularly noticeable when applied to Orito. 12 to 14, the center of rotation (rotation) between the panel bodies is the center line L1 (to L3) passing through the center of the panel in the thickness direction.
) Is shifted to one side in the opening and closing direction. For this reason, when one panel body 101a (111a, 121a) is opened and closed, the panel body 101a ((111a, 1
The side end opposite to the hinge of 21a) draws a trajectory that opens and closes once it expands in the wall direction, as indicated by an imaginary line M in FIG. Therefore, the space WD is provided between the wall (fixed body) and the panel body 101a (111a, 121a).
Must be large in advance. This gap W
D is a normally used folding door, which needs at least about 1 cm, which is a considerably large value for the gap between the doors, resulting in poor partitionability. The problem of the decrease in partitioning property is peculiar to a hinge having a structure in which the center of rotation (rotation) is off the center line of the door. To cover the gap WD, a work such as attaching a cover to the wall side can be performed, but this poses a problem in appearance and an increase in manufacturing cost.

The present invention has been made in view of the above-mentioned problems of the conventional hinge, and has a simple structure, practically no fear of pinching a finger, and excellent in partitioning property when closed. An object is to provide a door system using a hinge unit.

[0011]

In order to achieve the above object, a hinge unit according to the present invention comprises two rectangular plate-like panels each having a pair of side end faces in a direction perpendicular to the plate surface direction. Butts against each other along its longitudinal direction, and
A hinge unit that is rotatably connected to another panel body to form a door system. 2 above
Two rod-shaped support members to be attached to the side end surfaces of each of the two panel members, and an axial upper end surface and a lower end surface of each of the two support members pass through a center point in the plate thickness direction of the panel body. Four spur gears fixed to the position on the central axis so that the rotation center positions are aligned, and a pair of opposing spur gears of the four spur gears on the upper end face and the lower end face are connected to each other. And a connecting body that rotatably connects the two sets of the support body and the spur gear from the opposite side of the support body in a meshed state. A portion of each of the two pillars to be attached to the panel body is formed on a flat attachment surface, and two projections for attachment to the panel body are protruded from the attachment surface along the axial direction. . On the other hand, the surface opposite to the mounting surface of each of the two pillars is formed in a shape having a cross section orthogonal to the axial direction describing a semicircle according to the size of the spur gear.

Preferably, the two pillars are rotatable at at least one position in the longitudinal direction of the pillar while contacting each other, and are fixed to each of the pillars. Provided with a pair of joint members.

Further, in the door system of the present invention, two adjacent panel members out of a plurality of rectangular plate-like panel members are connected to each other by connecting the side end surfaces of the panel members in a direction orthogonal to the plate surface direction to the longitudinal direction. A door system that includes a hinge unit that abuts each other along a direction and rotatably connects to each other panel body, and opens and closes the plurality of panel bodies in a bellows shape. The hinge unit is attached to the side end face of each of the two panel bodies.
The rotational center position is aligned with the position of a central axis passing through the center point in the thickness direction of the panel body with the upper end surface and the lower end surface of the two rod-shaped support members and the two support members in the axial direction. The four fixed spur gears, and a pair of opposing spur gears of the four spur gears at the upper end face and the lower end face, respectively, are engaged with each other and are opposite to the support body. And a connecting body that rotatably connects the two sets of the support body and the spur gear to each other. A portion for attaching each of the two pillars to the panel body is formed on a flat attachment surface, and two projections for attachment to the panel body are formed on the attachment surface on the pillar body side along the axial direction. In addition to projecting, the surfaces opposite to the mounting surface of each of the two columns are formed in a shape having a cross section orthogonal to the axial direction describing a semicircle shape according to the size of the spur gear. . On the other hand, a portion for attaching each of the column members of each of the plurality of panel members is formed on a flat attachment surface, and a groove for fitting the two protrusions is formed on the attachment surface on the panel member side along the axial direction. Drill.

Preferably, the two pillars are rotatable at at least one position in the longitudinal direction of the pillar while contacting each other, and are fixed to each of the pillars. Provided with a pair of joint members.

[0015]

According to the hinge unit and the door system of the present invention, when the panel body is pushed (or pulled) in the longitudinal direction of the panel body, the panel body opens and closes while meshing with another opposing panel body. Is done. If the door system is a folding door, a plurality of panel bodies are opened and closed in a bellows shape. At this time, since the virtual rotation (rotation) center of the hinge unit coincides with the center line passing through the center of the panel body in the thickness direction, the end of the panel body opposite to the hinge unit is outwardly opened and closed. There is no swelling trajectory. This allows
A gap between a fixed body such as a wall and a panel body (opening / closing body) can be eliminated. Also, by making the diameter of the gear approximately equal to the diameter of the column, the gap between the two columns can be made almost zero (for example, 1 mm). Very good partitioning properties can be ensured without using such a method.

Further, the gear is provided only at the upper end and / or lower end of the column, and the thickness of the gear is formed of, for example, a thin spur gear, and the gap between the two columns is almost zero as described above. Since it is set to, there is no possibility of accidentally pinching an object when the door is closed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

1 and 2 show the appearance of a manual folding door 1 according to this embodiment. The folding door 1 includes two panel bodies 10a and 10b, and a hinge unit 11 provided between the panel bodies 10a and 10b. Panel body 1
The main parts of each of Oa and 10b are made of a wooden material here, and are formed to a predetermined thickness and size.

As shown in FIGS. 1 to 4, the hinge unit 11 includes two support members 20a and 20b. Each of the pillars 20a and 20b is made of an aluminum material in the form of a rod having a substantially semicircular cross section. The length of the pillars 20a and 20b substantially matches the height of the panel bodies 10a and 10b.
The maximum diameter matches the thickness of the panel bodies 10a and 10b.

As shown in FIG. 4, spur gears 22a and 22b are fixed to upper and lower end surfaces of the pillars 20a and 20b via fixed shafts 21a and 21b, respectively. Each of the spur gears 22a and 22b is made of, for example, resin and has a thickness of about 1 cm in the axial direction, which is thin. The two spur gears 22a and 22b can mesh with each other, and the upper ends (or lower ends) of the two spur gears 22a and 22b are connected to each other by a thin connecting plate 23 in the meshed state. Both ends of this connecting plate 23
The spur gears 22a, 22b are rotatably mounted on bolts 24a, 24b fixed at the axial center position. For this reason, the gears 22a and 22b are connected while being engaged with each other, and can freely rotate (rotate) with each other. When the gears 22a and 22b rotate, the pillars 20a and 20b fixed to the gears 22a and 22b also integrally rotate around their longitudinal center axes. Note that the gears 22a, 22b,
That is, the pillars 20a, 20b are connected to the bolts 24a, 24
The stopper mechanism b prevents the two parts from shifting in the vertical direction.

The columns 20a and 20b are provided with gears 22.
By appropriately selecting the diameters of a and 22b, the height of the teeth, and the like, the distance between them is set to be extremely narrow, about 1 mm. Then, in order to further eliminate the narrow gap, a sealing member 25 is inserted between the two pillars 20a and 20b with the folding door closed. This sealing member 25
As shown in FIG. 6, the support members 20a, 2
0b along the longitudinal direction on the opposite side
as and 20bs are formed, and one slit 2
An elongated sealing member 25 made of mohair or rubber is embedded in the entire slit 20bs at 0bs. Since a part of the sealing member 25 protrudes outward, the slits 20as and 20bs of the panel bodies 10a and 10b face each other in the closed state of the folding door. The partial tip fits in the other slit 20as.

As shown in FIG. 6, each of the pillars 20a and 20b also has two projections 20am and 20an (20bm, 20bm) on the side opposite to the slit 20as (20bs).
20bn) is formed in the vertical direction. Each panel body 10a
On one side surface of (10b), two grooves each having a shape matching the above-mentioned projection are formed. Therefore, each column 20a (20b) is connected to each panel 10a by using the groove as a guide.
(10b) is fitted as shown, and the slit 20aa (2
0bs) is fixed with screws B from the side.

On the other hand, on the other side of each panel body 10a (10b), a frame 26a (26b) having a shape symmetrical to the support body 10a (10b) is provided.
Fitting and screwing are performed as in (10b). Since the outer circumferences of the walls 26a and 26b on the wall side are arc-shaped, the gap between the frames 26a and 26b and the walls 27a and 27b can be set to a value that is almost equal to none. However, in consideration of natural play and looseness, About 1mm is left. Therefore, slits similar to those described above are formed in both the wall 27a (27b) and the frame 26a (26b).
The slits on the sides a and 26b are filled with elastic sealing members 28a and 28b as described above.

On the other hand, FIG.
As shown in the figure, slide shafts 30U and 30L are respectively protruded, and the slide shafts are embedded in walls and floors.
It is slidable in the horizontal direction (longitudinal direction of the panel body section) along 1U, 31L. The other panel body 10
Fixed shafts 32U and 32L are also protruded from the upper and lower end surfaces of b, and are supported by walls and floors so that they can only rotate.

The door system of this embodiment is configured and functions as described above. For this reason, by pulling the handle 33 (see FIG. 1) of one panel body 10a to the right in FIG.
While the panel bodies 10a and 10b bend in a bellows shape around the hinge unit 11, the slide shafts 30U and 30L move toward the fixed shafts 32U and 32L, and the doors open as indicated by phantom lines in FIG.

Conversely, when the handle 33 is pulled to the left in FIG. 1 from the door opened state, the folding door 1 can be closed, and the stopper (not shown) is brought into the closed state shown by the solid lines in FIGS.

The center of the gears 22a, 22b is
a, 10b are aligned with the center position in the thickness direction,
As shown in FIG. 5, the position of the virtual bending center Co of the hinge unit 11 associated with this opening / closing operation is
a, 10b are on the center line Lo. Accordingly, the movement trajectory of the ends of the panel bodies 10a and 10b at the time of opening and closing does not protrude outward unlike the conventional case. Therefore, the wall 27
a, 27b and gap W between panel bodies 10a, 10b
a and Wb can be set extremely small.

For this reason, the partitioning property can be remarkably improved without providing a cover for concealing the gap. Also,
The gap Wo between the columns 20a and 20b in the door open state
Is almost zero and there is almost no dead space,
A wider passage can be secured.

Further, the walls 27a, 27 in the door closed state
The gap between the panel body 10b and the panel bodies 10a and 10b and the gap between the panel bodies 10a and 10b are originally extremely small, but are almost completely sealed by the sealing members 28a, 28b and 25. Thereby, a much better partitioning property is achieved as compared with the conventional art.

The sealing members 28a, 28b, 25 need not always be provided. Because these gaps are originally smaller than the conventional ones as described above,
Even without the sealing member, the partitioning property is excellent.

On the other hand, the problem that a finger or the like is sandwiched between the panel bodies can be solved. The gap between the pillars 20a and 20b when the door is opened becomes almost zero, and the state does not change even when the door is closed. A relatively large gap is formed between the panel bodies when the door is opened as in the related art, and the gap is caught when the door is closed. There is no need to worry about pinching fingers or objects. Further, since the gears are provided only at extremely limited portions at the upper end and the lower end of the column, it is not assumed that the gears participate in such pinching.

Further, in this embodiment, the panel body opens and closes due to the meshing of the two upper and lower local gears in spite of the structure of the entire hinge, so that a smooth and stable opening and closing operation can be obtained, and the clogging of dust and the like can be achieved. It can be easily removed and maintenance is easy.

For this reason, the hinge unit of this embodiment has a wide range of application, and examples of its use include folding doors at store entrances and general house entrances, passages for general houses, rooms, toilets, and storage doors. There are a wide variety of products, such as folding doors for bathrooms, electric walls, electric garage doors, and telephone doors. In the above-described embodiment, a manual folding door has been exemplified.
By driving the slide shaft with a drive mechanism having an electric motor or the like, the present invention can be easily implemented on an electric folding door.

In the above embodiment, the material of the panel body is made of wood, but it can be applied to a door made of aluminum, for example. The support members 20a, 20b using the aluminum panel members 50a, 50b adjusting members 51a, 51b.
FIG. 7 shows the attachment to the frame b and the frames 26a and 26b. This figure corresponds to FIG.

Further, in the above embodiment, the panel 1
The frames 26a and 26b attached to 0a and 10b are not always necessary, and may be removed and the shape of the panel end may be processed as shown in FIG. 8 or FIG. FIG. 8 shows a rectangular panel end, and FIG. 9 shows a panel end having a semicircular cross section. The shape shown in FIG. 9 can make the gap narrower.

Further, as means for increasing the rigidity of the support body against deformation such as torsion and warping, as shown in FIG.
A disc-shaped joint member 60a, 60b may be inserted at least at one position in the middle of the support members 20a, 20b. The members 60a and 60b are inserted in a state where the support members 20a and 20b cut vertically are fixedly jointed,
And it is rotatable in contact with each other. Thereby, the rigidity of the upper and lower portions of each of the columns 20a and 20b is increased. Therefore, if the door is long in the vertical direction and warping or distortion is likely to occur, it is effective to provide such a joint member.

Further, as described above, the gears are not limited to being provided separately at the upper and lower ends of the support body. For example, when the door is light, the gears are provided only at one of the upper and lower ends. Is also good.

On the other hand, as one modification of the hinge, FIG.
A hinge structure like this is also possible. According to the structure of FIG.
The support body is integrated with both panel bodies 70a and 70b forming a folding door, and gears 71a and 71b are rotatably attached to, for example, notched ends at the upper and lower ends of the panel bodies 70a and 70b. Thus, a door structure in which the support of the hinge unit is integrated is also possible, and the same operation and effect as described above can be obtained.

Further, the door system to which the hinge unit of the present invention is applied is not limited to a folding door. For example, a door system between a fixed body such as a wall to which one side is fixed and a panel body, that is, the hinge unit of the present invention is used for a hinged door. It is also possible to apply.

[0040]

As described above, according to the hinge unit of the present invention and the door system using the hinge unit, a simple structure mainly including the column, the gears, and the coupling body can be used from the open state. It is possible to eliminate the pinching of objects when shifting to the closed state, reduce the dead space in the open state, and further improve the sealing performance in the closed state to improve the partitioning effect.
