Description

  The present invention relates to an exterior structure and a telescopic gate, and more particularly to a riveting structure for the pipe or a pivot made of the pipe.

  In exterior structures such as gates, fences, and carports, a structure is adopted in which a required member is brought into contact with the tip of a pipe and the required member is fixed to the pipe with a rivet. For example, in a pantograph type telescopic gate, the ends of one fixed pivot of the plurality of pivots in the vertical direction that connect the intersecting portions of a plurality of oblique members intersecting in an X shape so as to be relatively rotatable. Some are fixed to vertical bars on both the front and rear sides, and other movable pivots are slidable up and down relative to the vertical bars on both sides.

In this type of telescopic gate, a fixed pivot is formed by a pipe having a drawn portion formed by drawing at both ends. The enlarged diameter portion at the tip is engaged with the inner periphery of the throttle portion of the fixed pin shaft (Patent Document 1).
FIG. 7 of JP-A-10-153072

  In the conventional riveting structure, as shown in the case of the fixed pivot of the telescopic gate, the diameter of the rivet is set inside on the inner periphery of the throttle, even though the throttle has an inner shape that changes smoothly. Therefore, if there is a variation in the inner surface shape of the throttle portion, there is a drawback that the variation directly affects the engagement state of the enlarged diameter portion. Moreover, if the telescopic gate is used for a long period of time, the throttle part, the enlarged diameter part, and the engaging part are likely to be worn, and the wear may cause rattling or the rivet may be detached from the fixed pivot. There are also concerns.

Further, the door body 5 is provided with an intermediate drop bar device 16 at a substantially central portion in the left-right direction, and an end drop bar device 17 at the locking end frame 15.

  Each drop rod device 16, 17 has drop rods 20, 21 that are detachable with respect to the drop holes 18, 19 on the ground 2 side, and operating bodies 22, 23 that operate the drop rods 20, 21 in the vertical direction. I have. A traveling wheel 24 that travels on the ground 2 is provided at a substantially central portion of the door body 5 at the door end side.

  2 (A) and 2 (B), the pantograph mechanism 8 includes a plurality of pairs of intermediate link members 25 arranged in the left-right direction so as to intersect with each other in an X shape in plan view, and eight in plan view at both ends. It has a pair of end link members 26 arranged in a letter shape, and is extendable in the left-right direction while bending in the horizontal direction around the vertical axis via the connecting bars 9, 10 and the pivot 29. The pair of intermediate link members 25 are connected to each other by a connecting bar 9 at a substantially central intersection, and each pair of intermediate link members 25 adjacent in the left-right direction is rotated relative to each other by a connecting bar 10 at the tip. It is connected freely.

  The pair of end link members 26 are connected to the distal end portion of the intermediate link member 25 on the end portion side corresponding to the inner end side by a connecting bar 10 so that the cylindrical portion 30 on the outer end side is close to the front and rear. Thus, the connecting frame 11 is fitted into pivots 29 at both upper and lower ends so as to be relatively rotatable.

  The connecting frame 11 connects the pair of pantograph mechanisms 8 in the vertical direction on the end side, and the connecting frame 11 is arranged in the vertical direction between the upper and lower pantograph mechanisms 8. It is fixed in contact with the locking end frame 15. That is, as shown in FIGS. 3 to 7, the locking end frame 15 is provided with protrusions 33 at substantially the entire length in the vertical direction at both front and rear ends of the side wall 32 corresponding to the connection frame 11. The side wall 34 is fastened to the side wall 32 of the locking end frame 15 by a fastening unit 36 that is fitted between the portions 33 and disposed in the vicinity of the pantograph mechanism 8. The fastening unit 36 includes a fastening screw 37 and a contact plate 38 into which the fastening screw 37 is screwed. The contact plate 38 is fixed to the side wall 34 of the connection frame 11 by a rivet 39.

  As shown in FIGS. 3 to 7, pivots 29 made of a pipe material are fixed to the upper and lower ends of the connecting frame 11. The pivot 29 is inserted into a pair of front and rear shaft holders 41 formed inside the cylindrical connecting frame 11 and fixed by rivets 42 from the side wall 34 side.

  Each pivot 29 has a diameter so that a rivet hole 43 is fitted in a portion fitted to the shaft holding portion 41, and an engagement hole 44 is opened to an inner circumferential hole 45 in the vertical direction at an end opposite to the shaft holding portion 41. It is formed to penetrate in the direction.

  4 to 7, the rivet hole 43 and the engagement hole 44 have substantially the same diameter as the inner circumferential hole 45 of the pivot 29, and the intersection portion of the rivet hole 43 and the inner circumferential hole 45 is engaged. The intersecting portion between the hole 44 and the inner peripheral hole 45 is formed with a substantially right angle along each inner peripheral surface. The pivot 29 is fixed to the connection frame 11 by a rivet 42 driven into the rivet hole 43 from the side wall 34 side of the connection frame 11. The engagement hole 44 is covered from the outside of the cylindrical portion 30 of the end link member 26 fitted to the pivot 29.

  On both the upper and lower sides of the cylindrical portion 30 of the end link member 26, connection plates 46 and 47 for connecting the pair of pivots 29 back and forth are provided. The lower connecting plate 47 is fitted on the pivot shaft 29 between the cylindrical portion 30 of the end link member 26 and the connecting frame 11, and the side edge of the connecting plate 47 contacts the side wall 32 of the locking end frame 15 between the protrusions 33. It touches. The upper connecting plate 46 is in contact with the tip of the pivot 29 and is fixed to the pivot 29 by a rivet 48 penetrating in the vertical direction and driven into the inner peripheral hole 45. The connecting plate 46 constitutes a contact member, and also serves as a retaining plate for the end link member 26.

The rivet 48 is, for example, a blind rivet or the like, and has a head 49 and a shaft 50 integrated with the head 49 as shown in FIG. A diameter-expanded portion 51 that engages with the engagement holes 44 on both sides from the 45 side is formed. By enlarged diameter portion 51 Ru crimping the leading end of the shaft portion 49, which tip portion of the shaft portion 49 is expanded outward from the inner peripheral hole 45 side of the pivot 29, on both sides in the radial direction It engages with the engagement hole 44 in a state of biting into a substantially right-angled corner formed between the engagement hole 44. The rivet 42 is engaged from the rivet hole 43 to the inner peripheral hole 45 in substantially the same manner.

  In the telescopic gate having the above-described configuration, when the doorway 1 is closed, the door body 5 is extended and the locking end frame 15 is brought into contact with the locking receiving frame 7 and locked by the locking device. At this time, in each pantograph mechanism 8, the front ends of the pair of front and rear end link members 26 are connected to the front and rear pivots 29 on the connecting frame 11 side, and the locking end frame 15 is fixed to the connecting frame 11. The locking end frame 15 can be held at a predetermined angle with respect to the pantograph mechanism 8. Therefore, if the locking end frame 15 is aligned with the locking receiving frame 7, the opposing end surfaces of both can be contacted easily and reliably. Then, the dropping rods 20 and 21 of the intermediate dropping rod device 16 and the end dropping rod device 17 are dropped into the dropping holes 18 and 19 on the ground 2 side to lock the door body 5.

  On the end side of each pantograph mechanism 8, unlike the connecting bars 9 and 10 that connect the middle part up and down, each end link member 26 is pivotally supported by a pivot 29, and the pivot 29 has both upper and lower ends. Since the end portion side of the pantograph mechanism 8 is vertically connected through the connecting frame 11 fixed to the locking frame 11, the locking end frame 15 can be easily connected through the connecting frame 11.

  In addition, the two front and rear pivots 29 are fixed to the upper and lower ends of the connection frame 11, but connection plates 46 and 47 are provided on both upper and lower sides of the cylindrical portion 30 of the end link member 26 to connect the front and rear pivots 29. Therefore, the pivots 29 can be securely fixed to the upper and lower sides of the connecting frame 11, and the distance between the pivots 29 is widened back and forth, so that the expansion and contraction operation of the pantograph mechanism 8 is not hindered.

  Further, the connecting plate 46 abuts on the end surface of the pivot 29 and is fixed by the rivet 48. The engaging hole 44 is formed in the pivot 29, and the enlarged diameter portion 51 at the tip of the rivet 48 is the inner peripheral hole 45 of the pivot 29. The enlarged diameter portion 51 engages with the engagement hole 44 from the side and bites into a substantially right-angled corner formed between the inner peripheral hole 45 and the engagement hole 44. Therefore, the enlarged diameter portion 51 of the rivet 48 is reliably engaged with the pivot 29, and the connecting plate 46 that contacts the end surface of the pivot 29 can be easily and reliably fixed by the rivet 48.

  In addition, since the engagement hole 44 is only required to be processed in the pivot 29 made of a pipe material, the pretreatment can be simplified. In addition, an engagement hole 44 is formed in the middle of the pivot 29. Since the engagement hole 44 is covered with a cylindrical portion fitted to the pivot 29, the engagement hole 44 is exposed to the outside. There is nothing wrong.

  Further, since the connecting frame 11 is fixed to the locking end frame 15 by the fastening unit 36 in the vicinity of the pantograph mechanism 8 at both upper and lower end portions thereof, the pivot 29 has a pivot 29 on both the upper and lower sides. It is possible to reliably prevent a fall or the like.

  FIG. 8 illustrates a second embodiment of the present invention. This example illustrates the suspending side of a horizontal link type telescopic gate having the same configuration as that of the first example. The end link member 26 on the suspending side of the pantograph mechanism 8 is connected to the pivots 29 at both the upper and lower ends of the connection frame 11, and the connecting plates 46 that come into contact with both end surfaces of the pivot 29 are rivets 48 as in the first embodiment. It is fixed by.

  The hinge 12 that pivotally attaches the connecting frame 11 and the connecting member 13 by a vertical hinge shaft 55 has a U-shaped hinge fitting 56 fixed to the connecting frame 11, and the connecting member 13 is connected to the hinge fitting 56. The cylindrical portion 57 is pivotally supported by a hinge shaft 55. The hinge shaft 55 is made of a pipe material, and a retaining plate 58 is in contact with both end faces thereof and fixed by rivets 59. An inner peripheral hole 45 and an engagement hole 44 are formed in the hinge shaft 55 similarly to the pivot shaft 29 of the first embodiment, and the enlarged diameter portion 51 of the rivet 59 is engaged with the engagement hole 44. The engagement hole 44 is covered with the cylindrical portion 30 on the outer periphery of the hinge shaft 55.

  The same can be applied to the case where the retaining plate 58 is brought into contact with the end surface of the hinge shaft 55 made of a pipe material and the retaining plate 58 is fixed to the hinge shaft 55 by the rivets 59.

  9 and 10 illustrate a third embodiment of the present invention. In this embodiment, a telescopic gate employing the door body 5 of the vertical pantograph pantograph mechanism 62 is illustrated. As shown in FIG. 9, the telescopic gate body 5 includes a plurality of vertical frame members 63 arranged at equal intervals in the left-right direction, and a pantograph mechanism 62 configured to be extendable in the left-right direction.

As shown in FIG. 10, each vertical beam 64 has a rectangular tube shape, and has a pair of left and right inward ribs 65 bent inward on the pantograph mechanism 62 side, and a pair of left and right protruding ribs 66 on the opposite side. And an outward rib 67 that bends outward on the inside of the protruding rib 66. The inward rib 65, the protruding rib 66, and the outward rib 67 are provided over substantially the entire length in the vertical direction. A cover 68 is attached to the vertical beam 64 through a protruding rib 66 and an outward rib 67 over substantially the entire length in the vertical direction.

  As shown in FIG. 9, the pantograph mechanism 62 is configured by pivotally connecting the intersecting portions of a plurality of oblique link members 69 intersecting in an X shape by pin shafts 70 and 71 in the front-rear direction. . Among the plurality of crossing portions corresponding to each vertical frame member 63, one crossing portion is fixed to the vertical frame member 63 by a fixed pin shaft 70 as shown in FIG. 10, and the other crossing portion is a movable pin shaft 71. Thus, the vertical frame member 63 is slidably connected to the vertical frame member 63.

  The front and rear ends of the fixed pin shaft 70 pass through the inner wall 72 and are inserted into the vertical bars 64, and are fixed to the outer wall 73 of the vertical bars 64 by rivets 74. Engagement holes 44 in a substantially diametric direction are formed at both end portions of the fixed pin shaft 70 so as to open to the inner peripheral hole 45. The engagement hole 44 has substantially the same diameter as the inner peripheral hole 45 of the pin shaft 70, and the diameter-enlarged portion 51 on the shaft portion 50 side of the rivet 74 is engaged with the intersection of the engagement hole 44 and the inner peripheral hole 45.
