Specification

Folding door suspension mechanism and folding door system using this suspension mechanism

Technical field

[0001] The present invention relates to a folding mechanism for a folding door including a suspension rail attached to a lower side of a vertical opening of a housing, and a suspension wheel having a roller that rolls along the suspension rail, and the suspension mechanism. In particular, the present invention relates to a folding mechanism for folding doors having three or more door panel bodies, and a folding door using this hanging mechanism.

Background art

[0002] The inventor of the present application is a hinge unit described in Patent Document 1 in order to provide a hinge and a door system having a simple structure and having no fear of pinching fingers and practically excellent partitioning properties when closed. And a door system using this hinge unit was proposed.

For example, as shown in FIG. 20, the door system 101 includes a folding door 120 including two panel bodies 120a and 120b and a hinge unit 122 provided between the panel bodies 120a and 120b, and a three-side frame body. 111, and a support mechanism 118 that supports the folding door 120 so that it can be opened and closed. The support mechanism 118 includes a suspension rail 114 and a six-wheel suspension vehicle 117, and also serves as a suspension mechanism.

[0004] Hinging unit 122ί, Fig. 20 [As shown, remove the two props 123a and 123b. Each of the support bodies 123a and 123b is formed in a bar shape having a substantially semicircular cross section here, and its length substantially matches the height of the panel bodies 120a and 120b, and its maximum diameter is a panel body. 120a, 120b thickness [Match this!

[0005] As shown in FIGS. 21 (a) and (b), the spur gears 123a and 123b are fixed to the spur gears 125a and 125b via fixed shafts 124a and 124b, respectively. ! The spur gears 125a and 125b can be engaged with each other, and the upper end (or lower end) side of the spur gears 125a and 125b is connected to each other by a thin plate-like connecting plate 126 in the engaged state. Both ends of the connecting plate 126 are rotatably attached to bolts 127a and 127b fixed at the axial center positions of the spur gears 125a and 125b. For this reason, the gears 125a and 125b are connected in an engaged state and can rotate (rotate) freely. When the gears 125a and 125b rotate, The provided support columns 120a and 120b are also rotated around the central axis in the vertical direction. The gears 125a, 125b, that is, the support columns 120a, 120b, are not displaced from each other in the vertical direction by the stopper mechanisms of the bolts 127a, 127b.

On the other hand, as shown in FIG. 20, the upper frame 11 lu of the three-way frame 111 cuts a predetermined area of 2Z3 or more in the width direction, and embeds a suspension rail 114 in the cut portion.

[0007] Further, as shown in FIGS. 22 (a) and 22 (b), the six-wheel suspension vehicle 117 is accommodated in the suspension rail 114 and arranged so as to be freely movable along its longitudinal direction. Yes. A rotatable axle 117a is suspended from the six-wheel suspension wheel 117! The axle 117a is fixed at a predetermined position on the upper end surface of the panel body 120b. This fixed position is set to a predetermined position such that the folding door 120 is perpendicular to the three-way frame 111 so that the passable width is maximized when the door is fully opened. The six-wheel suspension vehicle 117 has at least a strength capable of supporting the suspension load of the panel body 120b. As the door is opened and closed, the six-wheel suspension vehicle 117 also rolls and moves within the suspension rail 114, allowing the sliding motion of the panel body 120b, and allowing the rotation of the axle 117a to allow the swing motion of the panel body 120b. .

[0008] According to the hinge unit and the door system using the hinge unit, the structure of the object when moving from the open state to the closed state with a simple structure including the column body, the gears, and the coupling body as main parts is provided. The pinch can be eliminated, the dead space in the open state can be reduced, and the partition performance can be improved by improving the sealing performance in the closed state.

[0009] In addition, for example, a single-wheel suspension vehicle used for accordion doors, etc. The door can be opened and closed smoothly because no bearing is used for the rotating shaft and the vertical axis is not fixed because of the hanging shaft. 6-wheel suspension 117 uses a bearing on the rotating shaft, so the roller rolls smoothly, while there is a problem that there is no need to install a slide roller or guide rail on the floor side. In addition, since it is supported by four rollers, the verticality is stable and the door can be opened and closed smoothly.

[0010] However, the folding door system including the hinge unit with the 6-wheel suspension vehicle has the following problems. First, as shown in Fig. 23, when the door is opened, the door panel always protrudes both inside and outside the room. For example, footwear etc. I don't want it to protrude from the front door. On the other hand, when it is used at the hotel entrance / exit, it cannot project to the corridor. Since the door panel protrudes on both the indoor side and the outdoor side, it is not possible to provide door stops at the upper and lower ends of the door panel, resulting in a gap, and as a result, intrusion of wind and rain cannot be prevented. Cannot be used at entrances and exits. Even when used indoors, there is a problem in sound insulation.

[0011] However, if the door panel is protruded only on the indoor side or the outdoor side, the weight is applied only to one side, and therefore the tilting moment to rotate the 6-wheel suspension vehicle in the vertical plane is Arise. In addition, since the door panel exists only on the indoor side or the outdoor side, when the door panel is rotated, the suspension wheel also has a rotational moment in the horizontal plane. Then, these moments may hinder the movement of the suspension car and hence the smooth opening and closing of the folding door.

[0012] The second problem is that, when used for a folding door having three or more door panels, as shown in FIG. 23, the six-wheel suspension vehicle 117 has a certain length in the direction of the suspension rail 114. In this case, the six-wheel suspension vehicles 117 and 117 interfere with each other and the door cannot be completely opened, and the effective opening width is reduced. In this case, not only the appearance when the door is opened is strong, but a wider opening width is required to secure the same effective width, which is uneconomical.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a suspension mechanism according to the present invention and a folding door system using the suspension mechanism will be described with reference to the accompanying drawings. 1 and 2 are external views showing an outline of the first embodiment of the folding door system 1 according to the present invention. In this embodiment, the case where the folding door system 1 is adopted as an entrance door of a detached house will be described as an example.

In the folding door system 1 shown in FIG. 1, an opening OP that forms the entrance of a room is defined by the three-sided frame 2 and the entrance floor 3. The three-way frame 2 is formed by integrally forming an upper frame 2u and vertical frames 2s and 2s on both sides thereof.

[0023] In addition to the three-way frame 2, this door system 1 includes three panel bodies 11 (rotary shaft side panel), 12 (intermediate panel), 13 (grip side panel) and the panel bodies 11, 12 The folding door 10 is composed of a hinge unit 20 mounted on the door and a hinge unit 21 mounted between the panel bodies 12 and 13. The main parts of the panel bodies 11, 12 and 13 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.

A suspension rail 5 is attached to the lower surface of the upper frame 2u of the three-way frame 2. As shown in FIG. 3, the suspension rail 5 is formed in a substantially hollow prismatic shape having a slit 5a provided along the length direction at the center of the lower side. Then, both sides of the lower slit 5a are running surfaces 5e of side rollers 42 and 42 of a suspension wheel 40 to be described later. A concave groove 5b having the same width as the slit 5a is provided in the center of the upper side along the length direction. Further, a female engagement piece 5c is projected from the top of both sides, and an engagement groove 5d is formed in the female engagement piece 5c.

[0025] The side surface of the suspension rail 5 is covered with an outdoor cover 14 and an indoor cover 15 as shown in FIG. A projection 15a is formed at the lower end of the indoor cover 15 along the length direction of the suspension rail 5, and the door-like ridges 8, 8, installed on the opening OP side of the vertical frames 2s, 2s, In addition, the gap between the opening OP and the folding door 10 is closed together with the step of the outdoor floor 5 that is one step down from the entrance floor 4, thereby preventing outdoor wind and rain from entering the indoor.

[0026] By attaching a weather strip made of a long material such as plastic or rubber to the surface of the protrusion 8 and the convex portion 15a that contacts the folding door 10, more sound insulation, air tightness, and water tightness can be obtained. Can be improved.

Rotation shafts 6U and 6L are fixed to the upper and lower end surfaces of the rotation shaft side panel 11, respectively. The rotary shafts 6U and 6L virtually form the same vertical axis. Among these, the rotating shaft 6U at the upper end is coupled to the receiving portion 7, and this receiving portion 7U is fixedly installed in a suspension rail 5 provided in the upper wall surface of the door system 1. The receiving unit 7U can adjust the position of the rotary shaft 6U, that is, the vertical direction of the rotary shaft side panel 11. The rotating shaft 6L at the lower end is rotatably supported by a receiving portion 7L formed at a predetermined position on the floor.

As shown in FIGS. 4 to 6, the hinge unit 20 includes two support columns 11a and 12a fixed to the panel bodies 11 and 12, respectively. Each of the support bodies 11a, 12a is made of, for example, an aluminum material formed in a rod shape having a substantially semicircular cross section. The length of the support bodies 11a, 12a substantially matches the height of the panel bodies 11, 12, and the maximum The diameter is matched to the thickness of the panel bodies 11 and 12.

As shown in FIGS. 4 and 5, helical gears 22a and 22b are fixed to the upper and lower end faces of the support columns 11a and 12a, respectively. Each of the helical gears 22a and 22b is made of a metal such as steel and has a thin axial thickness of about 1 cm, for example. Further, as shown in FIG. 6, the teeth of the helical gears 22a and 22b are not provided on the entire circumference, but the half circumference (180 °) and a slight margin α ° of “180 ° It is provided only in the range of Χα ° ”. In the case of a folding door in which the panel body is folded in parallel with each other, the range of teeth of the helical gears 22a and 22b is in principle within 90 ° of the circumference. However, in the present embodiment, the same helical gears 22a and 22b can be used regardless of whether the folding door is opened or closed inward or outward, and “90 ° + 90” is obtained so that the versatility can be obtained. The teeth for 180 ° of “°” are formed. In addition, the extra teeth are kept to a minimum of about 10 °, for example, and as will be described later, the certainty of the meshed state accompanying the rotation of the panel bodies 11 and 12 is guaranteed.

[0030] Helical gears 22a and 22b are cylindrical gears formed in a winding with helical teeth, and transmit rotational motion between two parallel support columns 11a and 12b. Helical gears are spur gears. There is no backslash (play between the teeth where the pair of gears mesh), and the meshing is smoother than that of the spur gear. No noise is generated. This noise problem becomes particularly prominent when spur gears are formed of metal materials in order to support the weight when the panel body is large or made of metal and has a weight force S. However, if a helical gear is used, such noise is not generated and the folding door can be opened and closed quietly. In this embodiment, the tooth trace is a general 45 degree angle (the tooth trace is inclined 45 degrees from that of a spur gear).

[0031] Both helical gears 22a and 22b are connected to each other at the upper end (and Z or lower end) side by a thin plate-like connecting plate 23 as a connecting body. Both ends of the connecting plate 23 are bolted to the helical gears 22a and 22b so as to be rotatable. For this reason, the helical 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 helical gears 22a and 22b are rotated, the support pillars 11a and 12a fixed to the helical gears 22a and 22b are also rotated around the central axis in the vertical direction.

[0032] Note that the helical gears 22a and 22b generate a thrust load (a load or a pressure parallel to the axial direction of the rotating shaft) in the axial direction (longitudinal direction) because the teeth are twisted. The plate 23 must be strong enough to support the axial thrust.

[0033] The details of the pillars 11a, 12a and the helical gears 22a, 22b will be described with reference to FIG. 7 and FIG. The support columns 11a and 12a are formed in a hollow cylinder shape that is substantially larger than a semicircle, and groove portions llal and 12al are provided at the center of the semicircle over the entire length from the upper end to the lower end.

[0034] The interval between the support bodies 11a, 12a is set to an extremely narrow value of about lmm by appropriately selecting the gear height of the helical gears 22a, 22b. In order to further eliminate the narrow gap, a sealing member 25 is inserted into the groove parts llal and 12al of both support bodies 11a and 12a. As shown in FIG. 7, the sealing member 25 is a member having elasticity such as a mower, rubber, beet (synthetic rubber) provided on the opposite side surfaces of the support columns 11a, 12a along the vertical direction. It consists of Since a part of the sealing member 25 protrudes outward, the groove parts llal and 12al of the support bodies 11a and 12a face each other in the closed state of the folding door, and the sealing member 25 is caused by the elasticity of the sealing member 25. The tip of the protruding part of this is in contact with the sealing member 25 of the other party to improve the cutting performance. Although not shown, the panel body 11 (13) also has the vertical frame 2s (2s) side described above. The sealing members 28a and 28b having the same elasticity as the above are attached.

The helical gears 22a and 22b are formed by two-stage cylindrical force having different diameters. That is, as shown in FIG. 8, helical gear teeth are cut on the outer periphery of a large diameter, and the portion corresponding to the string contacting the panel bodies 11a, 12a is cut to form a substantially semicircular shape. The small diameter portion is cut into a shape inscribed in the support pillars 11a and 12a to form fitting portions 22al and 22bl to be inserted into the support pillars 11a and 12a.

[0036] The helical gears 22a and 22b are attached to the support bodies 11a and 12a in the following procedure. First, the helical gear 26a and 22b are meshed with each other, and the helical gear 26a and 22b are meshed with each other. Connect so that it can rotate freely. Then, the fitting portions 22al and 22bl of the helical gears 22a and 22b are inserted into the support pillars 11a and 12a, and the screw 28 is attached to the support pillars 11a and 12a. The helical gears 22a and 22b are fixed to the column bodies 11a and 12a by pressing the tip of the screw 28 against the bottom of the recess 30 provided by the progressive insertion.

[0037] The hinge unit 21 also has a force substantially the same as that of the hinge unit 20. The hinge unit 20 and the hinge unit 20 are configured to be rotatably supported by a suspension wheel 40 that is slidably accommodated on the suspension rail 5. Different. Hereinafter, the suspension vehicle 40 will be described with reference to FIGS. 3 and 9. FIG. FIG. 3 is a side view of the suspension vehicle 40 viewed from the cross-sectional direction of the suspension rail 5, and FIG. 9 is a front view of the suspension vehicle 40 viewed from the entrance side force.

As shown in FIGS. 3 and 9, the suspension vehicle 40 includes a prismatic traveling body 41, two upper guide rollers 42 provided on the upper surface near both ends of the traveling body 41, and a traveling body 41. A lower guide roller 43 provided on the lower surface near one end and two pairs of side rollers 44 provided on both side surfaces near both ends of the traveling body 41 are provided.

For example, as shown in FIG. 10, the seven rollers 42 to 44 are configured such that a ball bearing 46 is disposed between the rollers 42 to 44 and the roller shaft 45, and the roller shaft 45 plays a role via the ball bearing 46. Supported to roll freely. The ball bearing 46 includes an inner ring 47, an outer ring 48 inserted and fixed to the rollers 42 to 44, a steel ball 49 loaded between the inner and outer wheels, a retainer 50 made of a plastic molded product, and the like.

[0040] The upper guide rollers 42 and 42 are fitted into the recessed grooves 5c of the suspension rail 5, as shown in FIGS. To do. As a result, the rolling of both ends in the front-rear direction along the suspension rail 5 of the traveling body 41 is suppressed, and the side roller 44 straightens the traveling surface 5e of the suspension rail 5 without yawing while swinging its head from side to side. Can be rolled into. In this case, the greater the distance between the front and rear upper guide rollers 42, 42, the more effective the yawing prevention. However, as shown in FIG. 9, there is a rotating shaft 6U and a receiving portion 7U that pivotally support the folding door 10 at the end of the suspension rail 5 on the rotating shaft side, and in order to prevent interference therewith, The length is such that it does not extend from the front of the rotating shaft side panel 11 when opened. Therefore, to secure the distance between the upper guide rollers 42, 42, ensure a sufficient length on the handle side of the suspension rail 5! /

[0041] Further, at the same time that the upper guide rollers 42, 42 are fitted in the concave grooves 5c of the suspension rail 5, the lower guide roller 43 is fitted in the slit 5a. The upper guide roller 43 and the lower guide roller 42 suppress the vertical roll of the traveling body 41, so that the rolling of the suspension vehicle 40 is prevented, and the folding door 10 can be smoothly moved without rattling. It can be opened and closed. Therefore, it is not necessary to provide a guide rail or the like for preventing the steady rest at the lower end of the folding door 10.

Next, FIG. 11 shows the relationship between the suspension wheel 40 and the hinge unit 21. In the present embodiment, the traveling body 41 of the suspension vehicle 40 has square pillars 41a and 41b having a square cross section overlapped with each other in two upper and lower stages, and bolt holes 41c and 41d drilled in each are connected to each other using bolts 51. Are formed together. However, the traveling body 41 may be integrally formed from the beginning using a rectangular column with a rectangular cross section! ,.

[0043] In addition, bolt holes 41e, 41e force S for connecting with the helical gears 22a, 22b are formed in the prism 41b. Therefore, the screw hole 52 is screwed from below the helical gear 22a (22b) into the bolt hole 31 of the helical gear 22a (22b), the bolt hole 23a of the connecting plate 23, and the Bonole hole 41e of the prism 41b. The helical gears 22a and 22b are connected so that they can mesh with each other and turn freely. In this case, since the helical gears 22a and 22b are fixed to the prism 41b, the connecting plate 23 is not necessarily required. In this embodiment, the upper and lower helical gears 22a and 22b at the upper and lower ends of the butterfly unit 20 and the helical gears 22a and 22b at the lower end of the butterfly unit 21 are attached to unify the appearance.

[0044] In this way, the suspension wheel 40 has the helical gears 22a and 22b at the upper ends of the suspension rail 5 and the hinge unit 21. At the same time, the suspension mechanism of the present invention is configured, and the helical gears 22a and 22b constitute the gear train of the present invention.

[0045] After the suspension wheel 40 and the helical gears 22a, 22b assembled in this way are loaded into the suspension rail 5, the fitting portions 22al, 22bl of the helical gears 22a, 22b are connected to the panel bodies 12, 13 Are inserted into the pillars 12b, 13a integrated with the screw 28, and the screw 28 is screwed into the screw holes 29 formed in the pillars 11a, 12a to be bottoms of the recesses 30 provided in the fittings 22al, 22bl. The helical gears 22a and 22b are fixed to the column bodies 11a and 12a by pressing the tip of the screw 28 to the right. Thus, the panel bodies 12 and 13 are attached to the suspension mechanism.

In this case, as shown in FIG. 12, the suspension rail 5 can be divided into two or more members. At this time, the engagement rod 16 is inserted and fitted into the engagement groove 5d of the female engagement piece 5c, whereby the two member force joints of the suspension rail 5 are connected without causing a step. In this way, even if a problem occurs in the suspension vehicle 40, the suspension rod 40 can be easily removed simply by removing one member of the suspension rail 5 by shifting the engagement rod 16 at the joint force of the engagement groove 5d. Can be released.

[0047] The folding door system 1 of the present embodiment is configured and assembled as described above. Therefore, as shown in FIG. 2, when the folding door 10 is in the fully closed state indicated by the phantom line in FIG. 2 (I in FIG. 2), the handle 9 of the handle side panel 13 is moved forward when it is outdoors. By pulling the handle, the handle side panel 13 rotates around the hinge unit 21 by pushing it away from the door when it is at the entrance.

[0048] This rotation is transmitted from the helical gear 22b of the hinge unit 21 to the helical gear 22a, and rotates the intermediate panel 12 in the opposite direction to the handle side panel 13. Similarly, this rotation is transmitted from the helical gear 22b of the hinge unit 20 to the helical gear 22a, and rotates the rotary shaft side panel 11 in the opposite direction to the intermediate panel 12.

[0049] At this time, a rotational moment also acts on the suspension wheel 40, but the upper guide roller 42 is in the concave groove 5b and is restrained from moving laterally, and the upper guide rollers 42 before and after the traveling body 41, Since there is a sufficient distance between 42, the upper guide rollers 42, 43 are hooked on the side of the concave groove 5b and the movement of the traveling body 41 is not obstructed.The suspension wheel 40 slides smoothly in the suspension rail 5. be able to. [0050] In this way, the suspension wheel 40 is drawn toward the rotary shafts 6U and 6L (Π in FIG. 2), and finally, the three panel bodies 11, 112, and 13 become parallel, and the virtual wheel in FIG. It reaches the fully open state indicated by the line (111 in Fig. 2).

[0051] On the contrary, when the folding door is fully opened, the panel body 13 is rotated around the hinge unit 21 by pulling the handle 9 toward the right vertical frame 2s in FIG. This rotation is transmitted from the helical gear 22b of the hinge unit 21 to the helical gear 22a, causing the intermediate panel 12 to rotate counterclockwise to the handle side panel 13. Similarly, this rotation is transmitted from the helical gear 22b of the hinge unit 20 to the helical gear 22a, and rotates the rotary shaft side panel 11 counterclockwise to the intermediate panel 12. As a result, the suspension wheel 40 is pulled toward the right vertical frame 2s, and finally, the three panel bodies 11, 112, 13 are arranged in a straight line, and the folding door is fully closed.

[0052] As described above, the folding door 10 can be opened and closed smoothly without causing the panel bodies 11, 12, 13 to protrude toward the entrance side. In addition, even when fully opened, the amount of projection of the panel bodies 11, 12, 13 to the outdoor side can be significantly reduced compared to a normal hinged door. This is particularly effective when it is used for a guest room door of a hotel, for example, and the amount of blocking the entrance in the guest room is small.

[0053] Next, several modifications of the suspension mechanism according to the present embodiment and the folding door system using the suspension mechanism will be described. FIG. 13 shows a modified example of the suspension vehicle.

[0054] As shown in Fig. 13, the suspension wheel 40A of the present modification is basically different from that in the first embodiment in that the lower guide roller 43 is also provided at the other end of the traveling body 41. Other configurations are substantially the same as those of the first embodiment, and the same reference numerals are given and description thereof is omitted.

[0055] As described above, in the folding door system according to the present invention, since the panel bodies 11, 12 and 13 protrude only in the lateral direction when opened, a large tilting moment acts on the suspension vehicle. To counter this force, it is advantageous to have more guide rollers. In addition, as described above, it is advantageous that the distance between the two guide rollers is large to counter yawing. Therefore, in the present modification, the lower guide roller 43 is provided at the end of the traveling body 41 on the side opposite to the existing lower guide roller 43.

However, in this configuration, the new lower guide roller 43 interferes with the bolt hole 41e of the traveling body 41A, and the bolt hole 31 of the helical gear 22a, the bolt hole 23a of the connecting plate 23, and There is a possibility that the bolt hole 41e of the prism 41b cannot be screwed with the single bolt 52. In this case, the helical gear 22a and the connecting plate 23, and the connecting plate 23 and the prism 41b are screwed and connected with separate bolts.

In order to solve this problem, a new lower guide roller 43 may be provided on the handle side panel 13 side as in the second modified example of the suspension vehicle shown in FIG. Although the resistance against yawing is lower than that according to the first modification, the same resistance as that according to the first modification can be obtained against the rolling moment.

FIG. 15 shows a third modification of the suspension vehicle. As shown in FIG. 15, the suspension wheel 40D of the present modification is the same as that of the first embodiment in that the upper prism 41a and the lower prism 41b are connected to the force only at the approximate center in the length direction. The other configurations are substantially the same as those of the first embodiment, and the same reference numerals are given and description thereof is omitted.

[0059] Bolt hole 41f is drilled at approximately the center in the length direction of upper prism 41a, and through hole 4lg is drilled at lower prism 41b at a position corresponding to bolt hole 4 If, The bolt hole 4 If and the through hole 4 lg are connected by a cap bolt 54. The cap bolt 54 head 54a is provided with a recess 54b into which a hexagonal wrench is fitted, and a recess 41i capable of accommodating the cap bolt 54 is provided at the lower end of the bolt hole 41g.

[0060] Therefore, the distance between the upper prism 41a and the lower prism 41b can be changed by fitting and turning a hexagon wrench in the recess 54b, so that the height of the panels 12, 13 can be easily adjusted. It becomes possible to do. In this case, since the nonel 12 and 13 are suspended on the lower prism 41b via the helical gears 22b and 23a and the support bodies 12b and 13a, the lower prism 41b is lifted by its own weight. There is no shakiness.

[0061] Also, the upper square column 41a has two holes in the longitudinal direction across the bolt hole 41f, and the lower square column 41b has bolt holes 41d at positions corresponding to the upper holes 41h and 41h. , 41d is drilled, and the borehole holes 41d and 41d are accumulated with the chopped bonoleto 55, 55 force ^, and the upper half of the chopped bonoleto 55, 55 screw is not engraved. Inserted at 41h.

[0062] The flaw hole 41h is an oval having a long diameter in the long side direction of the upper prism 41a, and the short diameter is formed to be substantially the same as the upper half of which the screw of the cutting bolt 55 is not screwed. . As a result, even if the rotational moment associated with opening and closing the folding door is applied to the suspension wheel 40D, the upper prism 41a and the lower While the lateral prism 41b is prevented from shifting to the left and right (laterally), the cutting bolt 55 is reliably inserted into the flaw hole 41h even if there is a manufacturing error.

[0063] Next, a modified example of the hinge unit will be described as a fourth modified example. As shown in Fig. 16, the hinge unit 21Αί of this modification is basically different from that of the first embodiment in that the four gears 22c, 22d, 22e, and 22f are connected by the connecting plate 23A. Other configurations are substantially the same as those of the first embodiment, and the same reference numerals are given and description thereof is omitted.

[0064] In the hinge unit 21 according to the first embodiment, pillar bodies having different diameters are required for each thickness of the panel body, which is not economical. Therefore, as in this modification, the helical gear 22d and the helical gear 22e are interposed between the helical gear 22c and the column body 12bA and the helical gear 22f and the column body 13aA. Therefore, even if the panel thickness is different, the same helical gear 22c and column 12bA, helical gear 22f and helical gear 22f and helical gear 22e can be obtained by adjusting the size of the helical gear 22d and the helical gear 22e. The effect that the column body 13aA can be used is obtained.

In this modification, the column body 12bA and the column body 13aA are included in the panel bodies 12 and 13. Further, the helical gear 22c and the helical gear 22f, and the helical gear 22d and the helical gear 22e must be the same size.

FIG. 17 shows a fifth modification. This modification basically differs from that in the first embodiment in that a concealed type auto hinge 53 is used instead of the lower rotating shaft 6L, and other configurations are substantially different from those in the first embodiment. The same reference numerals are used and the description is omitted. By adopting the auto hinge 53, it is possible to make a semi-automatic folding door system that automatically returns to the closed state when it is opened, although it depends on manual operation when the folding door is opened.

Next, a second embodiment of the hanging mechanism and the folding door system using the hanging mechanism according to the present invention will be described with reference to FIG. As shown in FIG. 18, the folding door system 1A according to the present embodiment is basically different from that in the first embodiment in that the rotary shaft 6L is driven by a drive mechanism having an electric motor or the like. Is substantially the same as in the first embodiment, and the same reference numerals are given and description thereof is omitted.

[0068] The electric folding door 10A shown in FIG. 18 is equipped with three panel bodies 11 (rotary shaft side panel), 12 (intermediate panel), 13A (handle opening side panel), and between these panel bodies 11 and 12. Hinges A knit 20 and a hinge unit 21 provided between the panel bodies 12 and 13A are provided, which are configured in the same manner as in the first embodiment. However, since it is a fully automatic folding door system with a drive mechanism, there is no need for a handle, and the width of the three panels can be made the same so that the opening side panel 13A does not need to allow for the handle installation allowance.

[0069] A notch 61 cut into a quadrangular shape is formed in the lower end corner on the wall surface side of the rotary shaft side panel 11. An AC type torque motor 62 is fixed vertically at the position of the notch 61. That is, as shown in FIG. 19, the torque motor 62 has its flange 62 a fixed to the vertical frame 2 s with a nut.

[0070] The main body cover 62b of the torque motor 62 has an outer peripheral surface formed in a semicircular cross section, and in a vertically placed state, rounded portions of the same diameter are positioned on the outer side and the inner side of the folding door.

Furthermore, the torque motor 62 has a motor body, a reducer, a limit switch, etc. (not shown) inside, and a motor output shaft 62c is extended for the reducer force. The output shaft 62c is coupled to a pivot arm 63 provided inside the panel body above the notch 61. Therefore, the rotation of the motor body is transmitted to the rotary shaft side panel 11 via the pivot arm 63, and the rotary shaft side panel 11 is identical to the motor output shaft 62c and the rotary shaft 6U on the upper end surface of the rotary shaft side panel. As a rotation axis, it can rotate around this rotation axis.

[0072] When the torque motor 62 rotates in a predetermined direction corresponding to the folding door opening direction of the rotary shaft side panel 11, the rotary shaft side panel body 11 rotates in that direction. The intermediate panel 12 rotates while being pulled through the hinge unit 20, and similarly, when the intermediate panel 12 rotates, it is urged by this and rotates while the counterpart open side panel 13 A is pulled through the hinge unit 21. Then, the folding door 10A is opened (see Fig. 2). When the torque motor 62 is rotated in the opposite direction, the rotary shaft side panel l ib is rotated in the opposite direction, and the other intermediate panel 12 is correspondingly rotated in the opposite direction while being pushed, Correspondingly, the other door 13A rotates in the opposite direction while being pushed, so that the folding door 10A is closed (see FIG. 2).

[0073] Further, in order to control the rotation of the torque motor 62, an optical sensor 64 and a manual pushbutton switch 65 are provided on the upper wall surface and side surface of the door entrance. These sensor signals and / or scans The switch signal is provided to the controller 66. The controller 66 is constituted by, for example, a CPU system or a sequence circuit, and gives a rotational drive signal for rotating the torque motor 62 forward or backward in response to an input sensor signal or switch signal. Thereby, the rotation direction of the torque motor 62 is controlled. Note that the position and number of the open / close control sensors and switches can be arbitrarily set according to the place where the folding door 10A is installed.

[0074] The folding door 1 OA combined with the suspension wheel 40 and the gear-type hinge units 20, 21 can be opened and closed smoothly automatically or Z and semi-automatically, and is the same as that obtained in the first embodiment. Benefit from the benefits.

[0075] Further, since the outer peripheral surface of the cover 62b of the torque motor 62 is configured to be rounded on both the outer side and the inner side of the folding door, care is taken whether the folding door to be applied is opened leftward or rightward. The same torque motor 62 can be used. In the case of this second embodiment, the force that opens right in FIG. 18 (see arrow IV in FIG. 19). This torque motor 62 can be used in the same way for the folding door that opens left (see arrow V in FIG. 19). Increases nature.

[0076] That is, it is not necessary for a contractor to stock and manufacture separately the torque motors having different cover shapes according to the opening direction of the folding door, and therefore, a cheaper folding door system can be provided.

[0077] At the same time, the gap Wcut (see Fig. 18) between the notch 61 and the torque motor 62 can be set to a minimum for both the left-open and right-open folding door systems. Can be raised.

[0078] 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.
