  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 7 are views showing an embodiment of the accordion door of the present invention.

  FIG. 1 is an overall view showing an accordion door of the present invention. In the figure, reference numeral 10 denotes a rail, and an accordion door main body 14 is suspended and supported by a plurality of runners 12 capable of traveling on the rail 10. The accordion door body 14 includes frames 16, 18 provided at both ends in the left-right direction, a hinge 20 that can be extended and contracted between the frames 16, 18, and a cloth that is connected to the hinge 20 and arranged before and after the hinge 20. , And a decorative covering material 22 made of plastic sheet, leather or the like.

  A plurality of hinges 20 can be provided at appropriate intervals in the vertical direction. A partial detail view of the hinge 20 arranged at the top is shown in FIG. As shown in the figure, the hinge 20 includes a pair of hinge pieces 24 and 25 having substantially the same length, which are pivotally connected to each other by a pivot 26 at a central portion thereof to form an X-shaped hinge element 28. Further, the end portions of the hinge pieces 24, 25 constituting the adjacent hinge elements 28 are connected to each other by a pivot 30, and a plurality of hinge elements 28 are connected one after another. Therefore, the hinge 20 has the four pivots at the opposite pivots 26 and 26 (the pivot connection point) and the opposite pivots 30 and 30 (the pivot connection point), and each of the hinge pieces 24 and 25 constituting a certain hinge element 28. A plurality of rhombus-shaped portions 32 each having a rhombus shape having four sides of the half and each of the half of the hinge pieces 25 and 24 constituting the adjacent hinge element 28 are connected. When the interior angle of the rhombus-shaped portion 32 changes and the rhombus-shaped portion 32 is deformed, the hinge 20 expands and contracts. A line connecting from the pivot 30 to the pivot 26 of a certain hinge element 28 and a line connecting from the pivot 30 to the pivot 26 of the adjacent hinge element 28 constituting the side of each rhombus-shaped portion 32. The interior angle formed between the two is called the hinge opening angle θ. The pivots 30 of the hinge elements 28 corresponding to the vertical directions of the hinges 20 are connected by wire rods 36 penetrating the pivots 30 in the vertical direction, and the vertical hinge elements 28 extend and contract in synchronization. To be formed.

  In this embodiment, when the accordion door is closed, the accordion door can be automatically moved in the closing direction by manually operating the accordion door in the slightly closing direction. As a means for this, a pair of tension springs 34, 34, which are elastic bodies, are provided on the rhombus-shaped portion 32 of the hinge 20 disposed at the uppermost and lowermost positions.

  Specifically, in the rhombus-shaped portion 32 in which the tension spring 34 is set, between the wire rods 36 and 36 penetrating the pair of pivots 30 and 30 that are opposite vertices of the rhombus-shaped portion 32, and the rhombus shape A pair of tension springs 34 and 34 are spanned symmetrically in the vertical direction with respect to the diamond-shaped portion 32 above and below the portion 32. In this manner, in order to easily and symmetrically arrange the tension springs 34, 34 in the vertical direction of the rhombus-shaped portion 32 of the hinge 20, it is preferable to use a spring bracket 38 as shown in FIG. This spring bracket 38 has a locking portion 38a in which one end of each of the tension springs 34 and 34 is locked to both upper and lower end portions thereof, beyond the intersection of the hinge pieces 24 and 25 constituting the apex 30 of the rhombus shaped portion 32. , 38a.

  The pivots 30, 30 that are the apexes facing each other of the rhombus-shaped portion 32 are always urged by the pair of tension springs 34, 34 arranged so as to sandwich the hinge 20 in this way.

  Although this tension spring 34 can be provided in all the rhombus-shaped portions 32, for example, as shown in FIG. 1, the rhombus-shaped portion 32 of the uppermost hinge 20 and the lowermost hinge 20 are You may make it provide alternately by the rhombus-shaped part 32. FIG. Or you may provide in the rhombus-shaped part 32 for every space | interval suitably, and can set suitably by the balance of the spring force and the weight of the accordion door main body 14. FIG.

  Moreover, as shown in FIG. 1, the brake 40 is provided in the hinge 20 which expands / contracts. The brake 40 plays a role of reducing the speed when the accordion door automatically moves by the urging force of the tension spring 34.

  Further, a stopper case 42 constituting a stopper is disposed in the accordion door main body 14, and in the stopper case 42, one end portion of the cord 44 is attached to the mainspring in which one end is fixed to a part of the stopper case 42. It is connected. The cord 44 is wound by the action of the mainspring in the stopper case 42 unless an external force is applied. The other end of the cord 44 is connected to the left and right inner side surfaces of the frame 18, and the cord 44 is pulled out or drawn from the stopper case 42 as the frame 18 moves. A cord stopper (not shown) is attached to an intermediate position of the cord 44, and the cord stopper engages with the stopper case 42 so that the accordion door can be kept open. A handle 50 is attached to the frame 18.

  In the accordion door configured as described above, the state shown in FIG. 2 is that the accordion door main body 14 is in the open state, that is, the hinge 20 is contracted. At this time, although a tensile force is applied to the tension spring 34, the hinge opening angle θ of each rhombus-shaped portion 32 is small, and the hinge pieces 24, 25 constituting the two sides of each rhombus-shaped portion 32 are tensioned. It is substantially parallel to the direction of the tensile force of the spring 34, and the rotational moment acting on each hinge piece 24, 25 is small. Therefore, the accordion door main body 14 is kept open by the stopper.

  When the accordion door is open, the stopper is released and the frame 18 is moved in the closing direction by holding the handle 50 provided on the frame 18 in FIG. 1 so that the runner 12 travels along the rail 10. As it goes on, the hinge 20 changes from the contracted state of FIG. 2 to the extended state. Thereby, hinge opening angle (theta) of each rhombus-shaped part 32 of the hinge 20 increases. When the hinge opening angle θ increases, the rotational moment due to the tensile force of the tension springs 34 acting on the hinge pieces 24 and 25 constituting the two sides of each rhombus-shaped portion 32 increases, and the thrust for extending the hinge 20 works. Even if the frame 18 is not moved, the runner 12 automatically travels in the rail 10 and the accordion door is closed. When the frame 18 is completely moved, the tensile force of the tension spring 34 acting on the hinge pieces 24, 25 still keeps the accordion door body 14 closed.

  Next, when the accordion door is opened again from the closed state, the frame 18 is moved in the opening direction by holding the handle 50. At this time, the hinge pieces 24 and 25 must be rotated in the opposite direction against the rotational moment acting on the hinge pieces 24 and 25 by the tensile force of the tension spring 34, but as described above, to some extent the accordion When the door is opened and the hinge opening angle θ of the rhombus-shaped portion 32 of the hinge 20 is reduced, the rotational moment is reduced, so that the operating force for moving the frame 18 is reduced, and the reaction force by the tension spring 34 is reduced. The accordion door can be opened by contracting the hinge 20 with a light force without being affected by the force. And if the accordion door main body 14 fully shrink | contracts and a stopper acts, the accordion door main body 14 will maintain an open state.

  Since the pair of tension springs 34 and 34 that operate as described above are arranged above and below the hinge 20 so as to sandwich the hinge 20, the wire 36 has a tensile force of the pair of tension springs 34 and 34. The wire rod 36 can maintain a substantially straight state because it acts almost symmetrically with respect to the hinge 20 and the rotational moments of the tension springs 34, 34 cancel each other around the hinge 20 (FIG. 7). (See (a)). On the other hand, when only one tension spring 34 is disposed in the vicinity of the hinge 20 asymmetrically, the tensile force acts on the wire 36 and bends in an arcuate shape to cause swelling on the surface of the decorative covering material 22. (See FIG. 7B). In the present embodiment, the appearance of the cosmetic coating material 22 from the outside can be improved without adversely affecting the surface of the cosmetic coating material 22 such as swelling.

  FIG. 8 is a schematic diagram showing another embodiment.

  In this embodiment, the tension springs 34 provided over the wire rods 36 penetrating in the vertical direction through the opposing pivot connection points 30, 30 of the rhombus-shaped portion 32 of the hinge 20 are arranged slightly spaced vertically. It arrange | positions so that it may be pinched | interposed into a pair of hinges 20 and 20 up and down. Even if it does in this way, the effect | action and effect similar to previous embodiment can be achieved, and the displacement of the wire 36 which arises with the wire 36 with the tension | tensile_strength of the tension spring 34 can be suppressed with the upper and lower hinges 20. FIG. And it can maintain the wire 36 in a substantially straight state, does not have an adverse effect of generating swelling on the surface of the cosmetic covering material 22, and can improve the appearance of the cosmetic covering material 22 from the outside. it can.

  FIG. 9 is a schematic view showing still another embodiment, and FIG. 10 is a partial perspective view thereof.

  In this embodiment, the rhombus-shaped portion 32 constituting the hinge is configured in a three-dimensional manner, and an intermediate portion is formed in the vertical direction so that the upper hinge portion 20A and the lower hinge portion 20B are separated. It is. Specifically, the pivot 30 that is one vertex of the rhombus-shaped portion 32 is dotted when viewed from the plane, but is separated into two via the wire 36 when viewed from the front, A tension spring 34 is arranged over the portion of the wire 36 that is in the middle of the separation.

  Even if it does in this way, the effect | action and effect similar to previous embodiment can be achieved, and the displacement of the wire rod 36 produced by the wire rod 36 by the tensile force of the tension spring 34 can be suppressed by the upper and lower hinge portions 20A, 20B. it can. And it can maintain the wire 36 in a straight state, does not have an adverse effect of generating swelling on the surface of the cosmetic covering material 22, and can improve the appearance of the cosmetic covering material 22 from the outside. .

  In the accordion door of the above example, when the accordion door is moved in the closing direction, the accordion door is automatically closed and moved in the opening direction. However, the accordion door is not limited to this. Moreover, although the tension | pulling spring was taken as an example as an elastic body, it does not restrict to this. For example, by placing a compression spring across the wires 36 and 36 so that the pivots 26 and 26 are biased toward each other, the accordion door is automatically opened when moved in the opening direction. When moving in the closing direction, it can also be performed manually.
