Description

[Technical field]

[0001] The present invention relates to a hoisting fitting, and more particularly to a hoisting fitting that can be easily and appropriately attached to a structure such as a light-transmitting plate when the structure is hoisted by a crane. [Background technology]

[0002] Noise insulation walls to be installed on roads and other areas are constructed, for example, by attaching hanging brackets to sound insulation boards, hoisting them with a wire attached to a crane, and dropping both ends of the boards between the flanges of H-shaped steel pillars, and stacking them one on top of the other in multiple layers.

[0003] Patent Document 1 discloses a hanging fitting that is attached to an opening that is formed at the upper end of the side of a sound insulating wall, with a large diameter at the bottom and a small diameter at the top, which can be attached to the sound insulating wall by one person, there is no risk of it coming loose during the hanging work, and furthermore, it can be easily removed after the hanging work is completed.

[0004] [Patent Document 1] JP 2016-160050 A Summary of the Invention [Problem to be solved by the invention]

[0005] Soundproofing panels include light-transmitting panels made of polycarbonate, acrylic, tempered glass, etc., and some have an aluminum frame attached to the body of the light-transmitting panel. These light-transmitting panels are installed by attaching hanging hardware to holes formed in the aluminum frame and hoisting it with a crane.

[0006] Fig. 1 is a plan view of a light-transmitting plate to which an aluminum frame is attached. An aluminum frame 50 is attached to the upper surface of the light-transmitting plate, and a round hole 50a and a long hole 50b are formed side by side. Fig. 2 shows a hanging bracket 60 (hereinafter referred to as a "conventional hanging bracket") used to hang up the light-transmitting plate.

[0007] The conventional hanging hardware 60 has an eye nut 61, a bolt 62, and a nut 63 with a washer. The bolt 62 is bent into a U-shape, and a thread is formed at the tip for screwing with the nut 63. When attaching the conventional hanging hardware 60 to the aluminum frame 50, the tip of the bolt 62 is inserted into the long hole 50b with the nut 63 removed, and the tip of the bolt 62 is made to protrude from the round hole 50a while tilting it along the curve of the bolt 62, and then the nut 63 is screwed onto the protruding tip of the bolt 62 to attach it. In this way, the conventional hanging hardware 60 can be easily attached to the aluminum frame 50.

[0008] However, in the past, when attaching the hanging bracket 60 to the aluminum frame 50, if the installation procedure was incorrect and the tip of the bolt 62 was inserted into the round hole 50a, protruding from the long hole 50b, and then screwed on the nut 63, the load would be concentrated locally on the washer of the nut 63 when the plate was lifted, causing the edge of the long hole 50b to deform or break, and causing the translucent plate to fall.

[0009] Therefore, an object of the present invention is to provide a hanging fitting used when lifting a structure having a long hole formed on its upper surface, which can be easily and appropriately attached to the structural part. [Means for solving the problem]

[0010] Books A hanging fitting according to one aspect of the invention comprises: a movable member through which the shaft is inserted and movable along the shaft; and a biasing means for biasing the movable member along the axial direction of the shaft toward the one end, causing the movable member to abut against the insertion member, wherein the longitudinal length of the insertion member is longer than the longitudinal length of the hanging hole, and the movable member has a shaft long hole through which the shaft is inserted, and two abutment portions that abut against two points on either side of a portion of the insertion member attached to the shaft by the axial member when biased by the biasing means, and the movable member has an arc-shaped portion when viewed from the front, and the shaft long hole is formed in the arc portion when viewed in a plan view. Effect of the Invention

[0015] According to this invention, the movable member is moved to the second position, the insertion member is tilted and inserted into the long hole of the structure, and then the insertion member is horizontally positioned and the movable member is moved to the first position, thereby making it easy to attach the hanging hardware to the structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] An embodiment of the hanging fitting of the present invention will be described with reference to the drawings.

[0018] 3, the hoisting hardware 1 according to this embodiment is attached to the light-transmitting plate 30 when the light-transmitting plate 30 is hoisted by a crane. The light-transmitting plate 30 has an aluminum frame 31 attached to its top, both side surfaces, and bottom surface, and the hoisting hardware 1 is attached to each of two points on its top surface.

[0019] The configuration of the hanging hardware 1 according to this embodiment will be described with reference to Figures 4 and 5. The hanging hardware 1 comprises a shaft 6, an insertion member 2 attached to one end of the shaft 6 so as to be able to swing and inserted into a long hole, described below, formed in the upper part of the aluminum frame, and a stopper 7 attached to the shaft 6 and movable along the axial direction of the shaft 6.

[0020] The insertion member 2 is attached to one end of the shaft 6 via a mounting bracket 3. As shown in Fig. 5(B), one end of the shaft 6 is processed into a flat plate shape. The mounting bracket 3 is composed of two plate-like members 3a and 3b, and is fixed to the shaft 6 with the flat-plate-shaped portion of the shaft 6 sandwiched between the plate-like members 3a and 3b.

[0021] Insertion holes 3c, 3d are formed in opposing positions of plate-like members 3a, 3b of mounting bracket 3. Similarly, insertion hole 2a is formed in insertion member 2. Insertion member 2 is fitted between plate-like members 3a, 3b, and after aligning insertion holes 3c, 3d with insertion hole 2a, bolt 4 is passed through and nut 5 is screwed in, whereby insertion member 2 is attached to mounting bracket 3 in a swingable manner.

[0022] Stopper 7 has a sector shape, and a long hole 7a is formed along the arc in the arc portion. Stopper 7 is attached to shaft 6 so as to be movable along the axial direction of shaft 6 by being inserted into long hole 7a from the other end of shaft 6. A washer 8, a spring 9, and a washer 10 are further inserted from the other end of shaft 6, in that order, and finally the other end of shaft 6 is closed by an eye nut 11.

[0023] The spring 9 biases the stopper 7 downward (towards one end of the shaft 6). This causes the stopper 7 to come into contact with the insertion member 2 and inhibit the swinging of the insertion member 2. In response to this, the stopper 7 is lifted against the biasing force of the spring 9 and pulled away from the insertion member 2, thereby releasing the inhibition of the swinging of the insertion member 2. Note that the position where the stopper 7 comes into contact with the insertion member 2 and inhibits the swinging of the insertion member 2 is sometimes referred to as the "swing inhibition position," and the position where the stopper 7 is pulled away from the insertion member 2 and the inhibition of the swinging of the insertion member 2 is released is sometimes referred to as the "swing inhibition release position."

[0024] It should be noted that, instead of the spring 9, another elastic member (rubber, etc.) that urges the stopper 7 downward may be used. Also, it is preferable that the spring 9 has an elastic force sufficient to allow the stopper 7 to be lifted with a human finger and pulled away from the insertion member 2.

[0025] Next, a method for attaching the hanging hardware 1 to an aluminum frame will be described with reference to Figs.

[0026] 6, a long hole 31a is formed in the upper surface of the aluminum frame 31. The length of the long hole 31a in the longitudinal direction is shorter than the length of the insertion member 2 in the longitudinal direction.

[0027] When attaching the hanging hardware 1, first, as shown in FIG. 7, the stopper 7 is lifted against the biasing force of the spring 9, and the insertion member 2 is inserted into the elongated hole 31a in an inclined (standing) state.

[0028] 8(A) and (B), after inserting the insertion member 2 into the long hole 31a, the position of the insertion member 2 is adjusted to be horizontal along the aluminum frame 31. This ensures that even if the hanging hardware 1 is pulled up, the insertion member 2 is caught on the inside of the long hole 31a and will not come out.

[0029] 9(A) and (B), the stopper 7 is lowered and fitted into the edge of the long hole 31a so that it comes into contact with the inside of the hole. At this time, the stopper 7 presses the insertion member 2 from above at two points and is biased downward (toward one end of the shaft 6) by the spring 9, so that the insertion member 2 does not come out of the long hole 31a. In this way, the stopper 7 prevents the insertion member 2 from swinging and prevents the insertion member 2 from tilting and coming out of the long hole 31a.

[0030] 10 and 11, the hoisting bracket 1 attached to the top surface of the aluminum frame 31 has a wire 40 hung from an eye nut 11. The crane then pulls up the wire 40 to hoist the light-transmitting plate 30. At this time, the shaft 6 can move along the longitudinal direction of the long hole 7a according to the hoisting angle α of the wire 40, so the load is not concentrated at one point.

[0031] When removing the hanging hardware 1 from the aluminum frame 31, first, the stopper 7 fitted into the long hole 31a is lifted and pulled away from the insertion member 2 to release the inhibition of the swinging of the insertion member 2. Next, the insertion member 2, which is in a horizontal position, is tilted (uprighted) and pulled out from the long hole 31a. In this way, the hanging hardware 1 can be easily removed from the aluminum frame 31.

[0032] As described above, the suspension fitting 1 of this embodiment is a suspension fitting used when hoisting a translucent plate 30 (an example of a "structure") having a long hole 31a formed on its upper surface, and comprises a shaft 6, an insertion member 2 whose longitudinal length is longer than the longitudinal length of the long hole 31a, which is swingably attached to one end of the shaft 6 and inserted into the long hole 31a, and a stopper 7 (an example of a "movable member") which is attached to the shaft 6 and can move along the axial direction of the shaft 6 to at least a first position and a second position, such that in the swing restraining position (an example of the "first position"), the stopper 7 comes into contact with the insertion member 2 to restrain the swing of the insertion member 2 caught inside the long hole 31a, and in the swing restraint release position (an example of the "second position"), it moves away from the insertion member 2 to release the restraint on the swing of the insertion member 2.

[0033] Therefore, with the hanging hardware 1 of this embodiment, the stopper 7 is moved to the anti-sway position, the insertion member 2 is tilted and inserted into the long hole 31a, and then the insertion member 2 is horizontally positioned before the stopper 7 is moved to the anti-sway position, thereby making it easy to attach the hanging hardware 1 to the translucent plate 30.

[0034] Furthermore, in order to fix the stopper 7 in the swing-preventing position, the hanging hardware 1 of this embodiment has a spring 9 (an example of a "fixing means") that biases the stopper 7 toward the insertion member 2. This allows the stopper 7 to reliably prevent the insertion member 2 caught inside the elongated hole 31a from swinging, and prevents the insertion member 2 from tilting and coming out of the elongated hole 31a.

[0035] Furthermore, stopper 7 of hanging hardware 1 of this embodiment has elongated hole 7a through which shaft 6 is inserted and formed along the longitudinal direction of stopper 7. As a result, shaft 6 moves along elongated hole 7a according to the hanging angle α during lifting, preventing localized load concentration and deformation or damage to hanging hardware 1 or aluminum frame 31.

[0036] Incidentally, if the hanging hardware 1 can fix the orientation of the insertion member 2 horizontally after inserting the insertion member 2 at an angle into the long hole 31a, the insertion member 2 can be prevented from slipping out of the long hole 31a and the light-transmitting plate 30 can be lifted safely. Therefore, another hanging hardware 1 that can fix the orientation of the insertion member 2 horizontally within the long hole 31a will be described with reference to Figures 12 and 13.

[0037] As shown in Figures 12 and 13, another hanging hardware 1B has a stopper 12 in place of the stopper 7 of the hanging hardware 1, a nut 13 in place of the spring 9 of the hanging hardware 1, and a shaft 14 in place of the shaft 6 of the hanging hardware 1. The stopper 12 is U-shaped and has an insertion hole (not shown) formed in the upper surface. The other end of the shaft 14 is inserted into the insertion hole, so that the stopper 12 is attached to the shaft 14 so as to be movable along the axial direction of the shaft 14. A nut 13 is further inserted from the other end of the shaft 14, and finally the other end of the shaft 14 is closed by an eye nut 11.

[0038] The shaft 14 is formed with a screw thread so as to screw into the nut 13. This allows the nut 13 to move along the axial direction of the shaft 14 while rotating. As shown in Fig. 13, the stopper 12 can be fixed in the swing-preventing position by moving the nut 13 downward (towards one end of the shaft 14). On the other hand, as shown in Fig. 12, the nut 13 can be moved upward (towards the other end of the shaft 14) to separate the stopper 12 from the insertion member 2, thereby releasing the inhibition of the swing of the insertion member 2.

[0039] When attaching another hanging hardware 1B to the long hole 31a on the top surface of the aluminum frame 31, first, the nut 13 and the stopper 12 are moved upward, and the insertion member 2 is inserted into the long hole 31a in a tilted (upright) state. Next, the posture of the insertion member 2 is adjusted to be horizontal so that it is aligned with the aluminum frame 31, and the stopper 12 is lowered to a position where it comes into contact with the insertion member 2 to suppress swinging, and further, the nut 13 is lowered so that it comes into contact with the stopper 12 to fix the stopper 12. Note that when removing another hanging hardware 1B from the long hole 31a on the top surface of the aluminum frame 31, this procedure can be performed in reverse. [Explanation of symbols]
