A hinge unit, wherein two panel bodies of rectangular parallelepiped plate shape are abutted on each other along the longitudinal direction with their side end faces in a direction orthogonal to the plate surface direction of the panel bodies aligned with each other and connected to each other so as to be rotated relative to each other to form a door system. The hinge unit comprises two bar-like strut bodies fitted to the side end faces of the two panel bodies, four sets of spur gears fixed to the axial upper and lower end faces of the two strut bodies with their rotating center axes aligned with the center axis of the panel bodies passing the center of the panel bodies in the plate thickness direction, and connection bodies connecting the two pairs of assembled bodies formed of the strut bodies and the spur gears rotatably to each other from the opposite side of the strut bodies with the pair of opposed spur gears among the four sets of spur gears meshed with each other at the upper and lower end faces. The hinge unit is characterized in that one of the strut bodies comprises, on its surface facing the other strut body, a swelled part swelled along the vertical direction, and the other comprises, in its surface facing the one strut body, a recessed part recessed in such a shape that can be engaged with the swelled part along the vertical direction. Thus, the hinge unit capable of completely eliminating the possibility of catching fingers therein can be provided by a simple structure.

Description

Specification

Hinge unit and door system

TECHNICAL FIELD [0001] The present invention relates to a hinge unit provided with a hinge that is inserted between a fixed body and an opening / closing body or between the opening / closing bodies to smoothly open and close the opening / closing body, and a door system using the hinge unit. .

Background art

[0002] Hinges, such as hinged doors and folding doors, can be attached to another open / close body or fixed body so that the open / close body can be freely opened and closed.

[0003] Although the conventional folding door using a hinge has a simple structure, there is a problem that a large gap is generated between the panel bodies when the door is opened, which creates a relatively large dead space. .

[0004] Further, in a conventional folding door using a hinge, the center of rotation (rotation) between the panel bodies is shifted from the center line in the plate thickness direction of the panel bodies to one side in the opening / closing direction. When opening and closing the side, the side edge opposite to the suspension side draws a trajectory that opens or closes once it expands in the direction of the wall. For this reason, a margin must be provided in advance between the wall (fixed body) and the panel body. This gap should be at least about 1 cm for a folding door that is normally used, and the door gap is considerably large, resulting in poor partitioning. This problem of reduced partitioning is unique to hinges with a structure in which the center of rotation (rotation) is out of the center line of the door. Although it is possible to work with a cover on the wall side to close this gap, there are problems with appearance and an increase in manufacturing costs.

[0005] Further, a relatively large gap is generated between the two panel bodies pivotally supported by the hinges when the door is opened, and when the folding door is closed by both the force and the door opening state force, There was concern about pinching fingers in the gap, especially in children. The force that can form the corners of the two panel bodies into a taper shape so as not to pinch the fingers or attach the cover. This will cause problems in manufacturing cost and appearance.

The inventor of the present application used a hinge unit that solved such a problem and the hinge unit. A door system has been developed (see, for example, JP-A-8-218740.) ₀ According to the door system using this hinge unit and this hinge unit, the gap between the two panel bodies is a spur gear. By selecting an appropriate gear height, etc., it is set to a very narrow value of about lmm. In order to further eliminate the narrow gap, the opposing sides of both panel bodies are closed between the two panel bodies with the folding door closed. Further, a sealing member 5 made of a resilient member such as a mower, rubber, beet (synthetic rubber) provided along the longitudinal direction is inserted. Thereby, the possibility of involving a finger or the like is almost completely eliminated.

[0006] However, the public facilities used by unspecified majority have neither the power nor the power to generate any unforeseen circumstances, so the designers and managers of such facilities are more complete. There is a need for a hinge unit and a door system that eliminate the risk of fingers being caught in the door.

The present invention has been made in view of the problems of the conventional hinges as described above, and has a simple structure.

An object of the present invention is to provide a hinge unit and a door system using the hinge unit that completely eliminate the possibility of involving a finger or the like.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of a hinge unit and a door system using the hinge unit according to the present invention will be described with reference to the drawings. 1 and 2 show a door system 1 according to this embodiment. The appearance of is shown. This door system 1 is configured in a folding door type including two panel bodies 10a and 10b and a hinge unit 11 provided between the panel bodies 10a and 10b. The main parts of the panel bodies 1 Oa and 10b are made of a wooden material or a metal material such as aluminum or steel plate, and are formed in a predetermined thickness and size.

On the other hand, of the two panel bodies 10a and 10b, rotary shafts 32U and 32L are respectively fixed to the upper and lower end surfaces of the right panel body 10b in FIG. The rotary shafts 32U and 32L virtually form the same vertical axis. Among these, the rotary shaft 32U at the upper end is coupled to the rotary shaft arm 33, and the rotary shaft arm 33 is fixed in a slide rail 34 provided in the upper wall surface of the door system 1. The rotary shaft arm 33 can adjust the vertical position of the rotary shaft 32U, that is, the panel body 1 Ob. The rotating shaft 32L at the lower end is rotatably supported by a receiving portion formed at a predetermined position on the floor.

[0014] Further, another rotating shaft 35 is fixed to the upper end surface of the left panel body 10a in FIG. The rotary shaft 35 is rotatably supported by a slidable six-wheel slide roller 36 that is accommodated in the slide rail 34. The rotary shafts 32U and 35 and the rotary shaft arm 33 are described in, for example, Japanese Utility Model Publication No. 7-24544, and the six-wheel slide roller 36 is described in, for example, Japanese Patent Laid-Open No. 9-144421. Can be used.

As shown in FIGS. 3 to 5, the hinge unit 11 includes two support bodies 20 and 21. Each of the support bodies 20 and 21 is made of, for example, an aluminum material formed into a rod shape having a substantially semicircular cross section, and the length thereof is substantially matched to the height of the panel bodies 10a and 10b. The maximum diameter is matched to the thickness of the panel bodies 10a and 10b.

As shown in FIGS. 4 and 5, spur gears 22 a and 22 b are respectively fixed to the upper and lower end surfaces of the support bodies 20 and 21 using screws 30. Each of the spur gears 22a and 22b is made of, for example, a resin and has a thin axial thickness of, for example, about 1 cm. Further, as shown in FIG. 5, the teeth of each of the spur wheels 22a and 22b are not provided on the entire circumference, and the half circumference (180 °) and a slight margin α ° of “180” are provided. It is provided only in the range of “° + 2α °”. In the case of a folding door in which the panel body is folded in parallel to each other, the range of teeth of the spur gears 22a and 22b is in principle within 90 ° of the circumference. However, in this embodiment, the same spur gears 22a and 22b are used regardless of whether the folding door is opened or closed inward or outward. It is possible to use, and the teeth of 180 ° of “90 ° + 90 °” are formed so that the versatility can be obtained. Further, the extra α ° teeth are suppressed to a minimum of about 10 °, for example, and the certainty of the combined state accompanying the rotation of the panel bodies 10a and 10b is guaranteed.

[0017] Both spur gears 22a, 22b are connected to each other at the upper end (or lower end) side by a thin plate-like connecting plate 23 while being in mesh with each other. Both ends of the connecting plate 23 are bolted by bolts 31 and 31 so as to be rotatable with respect to the spur gears 22a and 22b. For this reason, the spur gears 22a and 22b are connected to each other while being engaged with each other and can freely rotate (rotate) with each other. When the spur gears 22a and 22b are rotated, the column bodies 20, 21 fixed to the spur gears 22a and 22b are also integrally rotated around the longitudinal central axis. Note that the spur gears 22a and 22b (that is, the support columns 20 and 21) are not displaced from each other in the vertical direction.

[0018] As shown in FIG. 6, the column body 21 is fixed to the fixing portion 21a fixed to the end surface of the panel body 10b facing the other panel body 10a when the door is closed, and fitted to the fixing portion 21a. The fitting portion 21b is formed. These are, for example, extruded aluminum materials.

[0019] The fixing portion 21a includes a base portion 21al that abuts the end surface of the panel body 21a, and two protrusions that project from the base portion 21al to the panel body 10b side over the entire length from the upper end to the lower end of the base portion 21al. The strips 21a2 and 21a2 are provided with a pair of spur gear fixing portions 21a3 projecting in an arc shape over the entire length from the upper end to the lower end of the base portion 21al on the opposite side of the base portion 21al to the projection 21a2. The spur gear fixing portion 21a3 is also provided with a female engagement piece 21a4 protruding outward from the arc.

[0020] The ridges 21a2 and 21a2 are fitted into concave grooves provided in the panel body 10b, so that the column body 21 is firmly fixed to the panel body 10b without causing a positional shift. The pair of spur gear fixing portions 21a3 is fitted with the lower ends of spur gears 22b, into which bolts 31 are screwed, and the spur gear 22b is fixed to the panel body 21 in the female engagement piece 21a4. Screw 30 to be screwed

[0021] The fitting portion 21b has a substantially semicircular cross section and a smooth outer surface, and a bulging portion 21bl that bulges toward the panel body 10a when the door is closed at the center of the arc. Is provided.

[0022] Further, inwardly protruding ridges 21b2 and 21b2 are provided in the vicinity of both ends of the arc, and these ridges 21b2 and 21b2 are fitted in a gap between the base portion 21al and the female engagement piece 21a4. Wearing and fitting part 21b is fixed and the column 21 is formed.

On the other hand, as shown in FIG. 6, the column body 20 includes a recessed portion 20bl formed in a shape that engages with the bulging portion 21bl in place of the bulging portion 21bl of the column body 21. In this respect, it is fundamentally different from the support body 21, and the other configuration is substantially the same as that of the support body 21, and a description thereof will be omitted. When the door is closed, the bulging part 21bl engages the recessed part 20bl with a very narrow gap of about lmm, so the other side of the door cannot be seen.

[0024] In the conventional strut body, the fitting portion and the base portion are integrally formed in a substantially D shape, and a groove is provided at the position of the bulging portion 21bl and the recessed portion 20bl. After the screw is screwed into the base side to fix the column body to the panel body, elastic members such as mower, rubber, and beads (synthetic rubber) are inserted into the concave groove to The sealing portion was formed so as not to be involved. For this reason, after forming the sealing portion, the screw was not visible, and the appearance was not impaired.

[0025] With this force, as shown in the present embodiment, when the bulged portion 21bl and the recessed portion 20bl are provided at the position of the conventional concave groove, the screw head can be concealed by screwing in this portion. I can't do it, and my aesthetics are damaged. Therefore, in the present embodiment, the column bodies 20, 21 are disassembled into the fixing portions 20a, 21a and the fitting rods 20b, 21b, and the fixing rods 20a, 2 la are first used with screws or the like on the non-node bodies 10a, 10b. After the fixing, the fitting parts 20b and 21b are fitted into the fixing parts 20a and 21a, respectively, thereby forming the support columns 20 and 21. This makes it possible to fix the column bodies 20, 21 to the panel bodies 10a, 10b without exposing the fixing screw heads.

[0026] The door system 1 of the present embodiment is configured as described above. As a result, by pulling the handle 37 (see FIG. 1) of one panel body 10a to the right side of the figure, the panel bodies 10a and 10b bend in a bellows shape around the hinge unit 11, and the six-wheel slide roller 36 Moves to the rotating shaft 32 U side, and the door is opened as indicated by the phantom line in FIG.

On the other hand, when the handle 37 is pulled to the left in FIG. 1 from the door open state, the door system 1 can be closed, and a closed state shown by a solid line in FIG.

[0028] In this case, a finger or the like may be caught in the gap between the support column 21 and the support column 22 in the open state shown in FIG. When shifting from the open state to the closed state, as the door moves in the direction (A) in the figure, the column body 20 rotates in the (B) direction and the column body 21 rotates in the (C) direction. That is, when a finger or an object is sandwiched between the support column 21 and the support column 22, the finger or the like rotates in the direction of being caught.

[0029] Here, if the end of the support body has a smooth surface such as a mower, rubber, bead (synthetic rubber) or the like, and if a sealing portion made of a material is formed, the frictional resistance At the same time, there is a risk that fingers may actually get involved.

However, in the hinge unit 11 according to the present embodiment, both the bulging portion 21b and the recessed portion 20b have a smooth surface, so that the frictional resistance is small. As the 21 moves in the (B) and (C) directions, it moves in the (D) direction, that is, in the direction away from the fingers, so that the fingers are not caught. As a result, the door continues to move in the (E) direction without closing a finger or the like and reaches the closed state.

[0031] The embodiments described above are for illustrative purposes and do not limit the scope of the present invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, and these embodiments are also included in the scope of the present invention.

[0032] For example, the column body shown in the present embodiment has a recessed portion on the hanging base side and a bulging portion on the other side, but conversely, the bulging portion on the hanging base side and on the other side. Recesses may be provided Industrial applicability

[0033] According to the hinge unit and the door system using the hinge unit according to the present invention, an excellent effect can be obtained if the possibility of involving a finger or the like can be completely eliminated with a simple structure. .
