Description

  The present invention relates to a rotating member hinge device that foldably connects two adjacent members such as a door plate (panel) of a folding door, and in particular, between these members in a state in which these two members are folded. The present invention relates to an improvement of a rotating member hinge device provided with cover means for closing the space and preventing fingers from being pinched.

  One prior art folding door provided with this type of rotating member hinge device is shown in US Pat. In this folding door, the hinge cylinders 10 and 16 of the two swing members 8 and 9 of the hinge unit that foldably connect the two panel members 1a and 1b fill the semicircular gap when these panel members are folded. The cover means that is formed in a large size and closes the space formed between the panel members 1a and 1b when the panel members 1a and 1b are folded is rotated relative to the inner surfaces of the hinge cylinders 10 and 16. It consists of a plurality of pipe members 21 connected via a mandrel 7.

  However, the cover means of this structure requires the hinge cylinders 10 and 16 of the hinge unit to be formed in a size corresponding to the folding space of the two panel members, which increases the size of the hinge cylinder and greatly opens and closes the rotating member. There was a drawback that resistance was imparted.

  Another conventional folding door provided with this type of rotating member hinge device is disclosed in Patent Document 2. The cover means of the folding door includes a cover 11 disposed between the panel members 4 and 5 so as to cover a gap between the two panel members 4 and 5, and a cover holding member attached to the inner surface of the cover 11. 13 and a slider having a slide pin 19 slidably engaged with the guide hole 14 of the cover holding member 13 and attached to the opposing connecting ends of the panel members 4 and 5. In the cover 11, the slide pin 19 moves along the guide hole 14 as the panel members 4 and 5 are opened and closed so that the cover 11 always covers the gap between the panel members 4 and 5.

  In the cover means of this patent document 2, since the gap between the panel members 4 and 5 is covered, a finger is not inserted into the gap, but both the panel members 4 and 5 are in the middle of opening and closing the folding door. There is a possibility that a gap may be generated between the cover 11 and a finger (see FIGS. 2 and 3 in the same document).

  An example in which the rotating member hinge device of the present invention (in the following embodiments, the rotating member is foldable, which is hereinafter referred to as a folding member hinge device) is applied to a folding door will be described in detail with reference to the drawings. FIG. 1 shows a folding door 1 having a folding member hinge device 10 to which the present invention is applied. In the illustrated embodiment, a sliding vehicle 3U slidably engaged with upper and lower slide rails 2U, 2D. 3D, which includes first and second panel members (first member, second member) 4 and 5, and these panel members 4 and 5 are foldably connected by the folding member hinge device 10 of the present invention. ing.

  As shown in FIGS. 2 and 3, the folding member hinge device 10 includes at least one hinge unit 20 that foldably connects the first panel member 4 and the second panel member 5, the first panel member 4, and the first panel member 4. The cover means 30 closes the space between the two panel members 5.

  In the form shown in the figure, two upper and lower hinge units 20 are provided. These hinge units 20 include a first blade 24A integrated with the intermediate hinge tube 22M and a second blade 24B integrated with the both-end hinge tube 22E. These hinge cylinders 22M and 22E are rotatably supported on the hinge shaft 26. The hinge shaft 26 is used in common for the upper and lower hinge units, and also functions as a support shaft for the rotation of the cover member of the cover means 30 described later so as to function as the first panel member 4 and the second panel member 5. The part which extends over the entire length and protrudes from the hinge cylinder 22E at both ends is supported by the cover member by the hinge shaft supports 28U and 28D.

  As shown in detail in FIG. 3, the cover means 30 is a hollow having an arcuate outer peripheral surface 32P corresponding to the arcuate cutouts 4N and 5N at the opposite edges of the first panel member 4 and the second panel member 5. The columnar cover member 32 follows the opening and closing of these members 4 and 5 when the first panel member 4 and the second panel member 5 are opened and closed. Are held between the first panel member 4 and the second panel member 5 via the hinge unit 20 by a flat wall surface 32F opposite to the arcuate outer circumferential surface 32P.

  More specifically, the columnar cover member 32 is formed of a hollow body having a semi-cylindrical cross section with an arc-shaped outer peripheral surface 32P and a flat wall surface 32F. And a shaft engaging groove 32G into which a half of the cross section of the hinge shaft 26 is engaged and an opening 32M corresponding to the notch 32N. As shown in FIG. 3, in the first panel member 4 and the second panel member 5, the blades 24A and 24B are engaged with the hinge unit mounting position, and the inner surfaces of the blades 24A and 24B (surfaces opposite to the mounting surfaces). Has blade-engaging dents 4R and 5R so as to substantially coincide with the inner surfaces of the first panel member 4 and the second panel member 5. Therefore, as shown in FIG. 4A, the hinge unit 20 is attached to these panel members 4 and 5 so that the inner surfaces thereof coincide with the inner surfaces of the first panel member 4 and the second panel member 5, respectively. Further, the cover member 32 is rotatably supported on the hinge shaft 26 of the hinge unit 20. In FIG. 3, reference numeral 32 </ b> C is a cap that closes the upper and lower open ends of the hollow columnar cover member 32.

  As shown in FIG. 4, the cover means 30 follows the blades 24 </ b> A and 24 </ b> B of the hinge unit 20 that is displaced according to the opening and closing of the first panel member 4 and the second panel member 5. A cover holding part 34 is provided to hold the space between the first panel member 4 and the second panel member 5 so as to close the first panel member 4, and the cover holding part 34 moves toward the inner surface of the columnar cover member 32. It comprises a holding piece 36 that is displaced following the opening and closing of the panel member 4 and the second panel member 5. In the form shown in the figure, the holding piece 36 is formed integrally with one (or both) of the intermediate hinge cylinder 22M of the hinge unit and the two end hinge cylinders 22E.

  As can be seen from FIG. 4, the holding piece 36 is integrally formed with the corresponding hinge cylinders 22M and 22E so as to be perpendicular to the blades 24A and 24B (see reference numerals 36A and 36B). With this configuration, as shown in FIG. 4D, when the first panel member 4 and the second panel member 5 are completely opened, the holding pieces 36A and 36B engage with both sides of the inner surface of the columnar cover member 32. Then, the columnar cover member 32 is positioned at a position where the space S between the first panel member 4 and the second panel member 5 is closed.

  Next, the opening / closing operation of the folding door 1 using the folding member hinge device 10 of the illustrated form will be described with reference to FIG. 4. In the state where the folding door 1 is completely closed (see FIG. 4A). The cover member 32 of the cover means 30 of the folding member hinge device 10 has an arcuate outer peripheral surface 32P corresponding to the arcuate inner surface of the notch 4N of the first panel member 4 and the notch 5N of the second panel member 5. Thus, it is stored in the space S between these panel members 4 and 5.

  From this state, the first panel member 4 and the second panel member 5 of the folding door 1 are opened so as to be folded, and an open / closed intermediate state in which these panel members 4 and 5 are substantially perpendicular is shown in FIG. . Since the cover member 32 is rotatably held by both the first panel member 4 and the second panel member 5, even if the first panel member 4 and the second panel member 5 are opened so as to be folded, the cover member 32 is covered. The member 32 holds the position as it is (the same position as that in FIG. 4A). Even when the cover member 32 is rotated by an external force applied to the cover member 32 by mistake from the open / closed intermediate state of FIG. 4C by hand (FIG. 4C). 4 (B)), the holding pieces 36A, 36B integral with the blades 24A, 24B engage with either side of the inner surface of the columnar cover member 32, and the space S remains closed. A finger or the like does not enter S.

  In the position shown in FIG. 4C, the cover member 32 is an intermediate position in which the space S in the notch of the two panel members 4 and 5 is symmetrical, and the panel members 4 and 5 are moved from this position. Further, the cover member 32 is further opened and reaches the fully open position (completely folded position) shown in FIG. .

  Finally, when the two panel members 4 and 5 reach the fully folded position where the two panel members 4 and 5 are fully opened, the holding pieces 36A and 36B integrated with the blades 24A and 24B are, as shown in FIG. The cover member 32 is positioned at a symmetrical position that closes the space S by engaging with both sides of the inner surface of 32.

  When the two panel members 4 and 5 are sequentially closed from the fully open (folded) position of FIG. 4D, the position returns to the fully closed position (deployed position) of FIG. 4A through the position of FIG. . As described above, when the cover member 32 is rotated by an external force when it is in the position of FIG. 4C (see FIG. 4B), the holding piece integral with the blades 24A and 24B. Since the space A remains closed because the 36A and 36B engage with either side of the inner surface of the columnar cover member 32, a finger or the like does not enter the space S. As shown in FIG. 4A, the flat wall surface 32F substantially coincides with the blades 24A and 24B, and the arcuate outer peripheral surface 32P coincides with the arcuate cutouts 4N and 5N of the panel members 4 and 5. It fits in the space S of the two panel members 4 and 5.

  In the above embodiment, the columnar cover member 32 is rotatably supported by the hinge shaft 26 of the hinge unit 20, but is rotatably supported by a hinge shaft separate from the hinge shaft 26 of the hinge unit 20. Also good. Moreover, although said embodiment is a folding door which two panel members 4 and 5 rotate, one of the two panel members 4 and 5 may be fixed and the other may rotate like a normal door. . For example, when the panel member 4 is fixed and the panel member 5 is rotatable with respect to the panel member 4, the completely closed state shown in FIG. 4A corresponds to FIG. 4B. The state (the state in which FIG. 4B is displaced 45 ° counterclockwise) is reached, and the columnar cover member 32 does not move until this state. When the panel member 5 is further opened from a state corresponding to FIG. 4B, the holding piece 36B pushes the inner surface of the columnar cover member 32, and the panel member 5 and the columnar cover member 32 are interlocked. Then, in a state corresponding to FIG. 4D, the two panel members 4 and 5 reach the fully folded position where they are completely opened.

  Moreover, in the said embodiment, although the notch parts 4N and 5N of the 1st member 4 and the 2nd member 5, and the outer peripheral surface 32P of the columnar cover member 32 are circular arc shape, the cover member 32 and the 1st member 4 are the same. The first member 4 and the first member 4 can be accommodated in the notches 4N and 5N at the opposite edges of the second member 5 and do not interfere with the rotation of the first member 4 and the second member 5. The cutout portions 4N and 5N of the two members 5 and the outer peripheral surface 32P of the cover member 32 may have a shape other than an arc shape.

  Further, in the above embodiment, the cover member 32 is rotatably supported by the hinge shaft 26, but may be fixed to the hinge shaft 26 at a position other than the hinge unit 20. In this way, even when an external force is applied to the cover member 32 in the state of FIG. 4C, the cover member 32 is not displaced from the state of FIG. 4C to the state of FIG. 4B. . Therefore, in this case, the holding pieces 36A and 36B are unnecessary.

  According to the present invention, the cover member is not held by the hinge cylinder of the hinge unit, but is held by the rotating member via the hinge unit of the normal form. There is no need to create a gap for inserting a finger between the rotating member in any process of opening and closing the rotating member, and the rotating member can always be opened and closed safely. The nature is great.
