Description

This invention relates to a hoisting fixture, in particular a hoisting fixture that can be easily and appropriately attached to a structure such as a light-transmitting plate when the structure is hoisted by a crane.

Sound insulation walls installed on roads and other areas are constructed, for example, by attaching hoisting brackets to sound insulation panels, hoisting them with wires attached to a crane, and dropping both ends of the panels between the flanges of supports made of H-shaped steel, then stacking them one above the other in multiple layers.

Patent Document 1 discloses a hanging bracket that is attached to an opening that is formed at the top end of the side of a soundproof wall and has a large diameter at the bottom and a small diameter at the top, and that can be attached to the soundproof wall by one person, without the risk of it coming loose during the hanging work, and that can be easily removed after the hanging work is completed.

JP 2016-160050 A

Translucent panels made of polycarbonate, acrylic, or tempered glass are also used as soundproofing panels, and some have an aluminum frame attached to the main body of the translucent panel. These panels are installed by attaching hanging hardware to holes in the aluminum frame and hoisting it with a crane.

Figure 1 is a plan view of a light-transmitting plate with an aluminum frame attached. An aluminum frame 50 is attached to the top surface of the light-transmitting plate, and round holes 50a and long holes 50b are formed side by side. Figure 2 shows a hanging bracket 60 (hereinafter referred to as a "conventional hanging bracket") used to hoist this light-transmitting plate.

The conventional hanging bracket 60 has an eye nut 61, a bolt 62, and a nut with a washer 63. The bolt 62 is bent into a U-shape, and a thread is formed at the tip for screwing into the nut 63. When attaching the conventional hanging bracket 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 bracket 60 can be easily attached to the aluminum frame 50.

However, if the installation procedure is incorrect when attaching the conventional hanging bracket 60 to the aluminum frame 50, and the tip of the bolt 62 is inserted into the round hole 50a and protrudes from the long hole 50b, and then the nut 63 is screwed in, the load is concentrated locally on the washer of the nut 63 when lifting, causing the edge of the long hole 50b to deform or break, and causing the translucent plate to fall.

Therefore, the object of this invention is to provide a hanging hardware that can be used to hoist a structure having a long hole formed on its upper surface, and that can be easily and appropriately attached to the structure.

a movable member through which the shaft is inserted and which is movable along the shaft; and a biasing means for biasing the movable member along the axial direction of the shaft toward the one end of the shaft, thereby 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 arc portion when viewed from the front, and the arc portion when viewed in a plan view has the shaft long hole formed therein.

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 moved to the first position, so that the hanging hardware can be easily attached to the structure.

An embodiment of the hanging hardware of the present invention will be described with reference to the drawings.

As shown in FIG. 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 sides, and bottom, and the hoisting hardware 1 is attached to each of the two points on its top surface.

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 includes a shaft 6, an insertion member 2 that is attached to one end of the shaft 6 in a swingable manner and inserted into a long hole (described later) formed in the upper part of the aluminum frame, and a stopper 7 that is attached to the shaft 6 and can move along the axial direction of the shaft 6.

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

Through holes 3c and 3d are formed at opposing positions on the plate-like members 3a and 3b of the mounting bracket 3. Similarly, a through hole 2a is formed in the insertion member 2. The insertion member 2 is fitted between the plate-like members 3a and 3b, and the through holes 3c and 3d are aligned with the through hole 2a. The bolt 4 is then passed through and the nut 5 is screwed in, so that the insertion member 2 is attached to the mounting bracket 3 in a swingable manner.

The stopper 7 is fan-shaped, and a long hole 7a is formed along the arc in the arc portion. The stopper 7 is attached to the shaft 6 so that it can move along the axial direction of the shaft 6 by being inserted into the long hole 7a from the other end of the shaft 6. A washer 8, a spring 9, and a washer 10 are then inserted from the other end of the shaft 6, in that order, and finally the other end of the shaft 6 is closed by an eye nut 11.

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, the inhibition of the swinging of the insertion member 2 is released by lifting the stopper 7 against the biasing force of the spring 9 and pulling it away from the insertion member 2. 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 called 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 called the "swing inhibition release position".

In place of the spring 9, another elastic member (rubber, etc.) that biases the stopper 7 downward may be used. In addition, 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.

Next, we will explain how to attach the hanging bracket 1 to the aluminum frame using Figures 6 to 10.

As shown in FIG. 6, a long hole 31a is formed on the top surface of the aluminum frame 31. The longitudinal length of the long hole 31a is shorter than the longitudinal length of the insertion member 2.

When attaching the hanging bracket 1, first, as shown in FIG. 7, lift the stopper 7 against the biasing force of the spring 9, and insert the insertion member 2 in a tilted (upright) position into the long hole 31a.

Next, as shown in Figures 8(A) and (B), after inserting the insert member 2 into the long hole 31a, the position of the insert member 2 is adjusted to be horizontal so that it is aligned with the aluminum frame 31. This ensures that the insert member 2 is caught on the inside of the long hole 31a and will not come out even if the hanging hardware 1 is pulled up.

Next, as shown in Figures 9(A) and (B), the stopper 7 is lowered and fitted so that it is in contact with the edge of the long hole 31a. At this time, the stopper 7 presses the insertion member 2 from above at two points and is biased downward (towards 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.

As shown in Figures 10 and 11, the hanging bracket 1 is attached to the top surface of the aluminum frame 31, and the wire 40 is hung from the eye nut 11. The crane then lifts the wire 40 to hoist the translucent plate 30. At this time, the shaft 6 can move along the longitudinal direction of the long hole 7a according to the hanging angle α of the wire 40, so the load is not concentrated at one point.

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 of the long hole 31a. In this way, the hanging hardware 1 can be easily removed from the aluminum frame 31.

As described above, the hoisting hardware 1 according to this embodiment is a hoisting hardware used to hoist a light-transmitting plate 30 (an example of a "structure") having a long hole 31a formed on its upper surface, and includes 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, and in the swing-restraining position (an example of a "first position"), the stopper 7 comes into contact with the insertion member 2 to suppress the swing of the insertion member 2 caught inside the long hole 31a, and in the swing-restraining release position (an example of a "second position"), it moves away from the insertion member 2 to release the inhibition of the swing of the insertion member 2.

Therefore, with the hanging hardware 1 according to this embodiment, the stopper 7 is moved to the anti-sway release position, the insertion member 2 is tilted and inserted into the long hole 31a, and then the insertion member 2 is brought to a horizontal position and the stopper 7 is moved to the anti-sway position, allowing the hanging hardware 1 to be easily attached to the light-transmitting plate 30.

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

Furthermore, the stopper 7 of the hanging hardware 1 of this embodiment has a long hole 7a through which the shaft 6 is inserted and which is formed along the longitudinal direction of the stopper 7. As a result, the shaft 6 moves along the long hole 7a according to the hanging angle α during lifting, preventing the load from concentrating locally and causing deformation or damage to the hanging hardware 1 or the aluminum frame 31.

However, if the hoisting fixture 1 can fix the position 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 translucent plate 30 can be lifted safely. Therefore, another hoisting fixture 1 that can fix the position of the insertion member 2 horizontally within the long hole 31a will be described using Figures 12 and 13.

As shown in Figures 12 and 13, another hanging hardware 1B has a stopper 12 instead of the stopper 7 of the hanging hardware 1, a nut 13 instead of the spring 9 of the hanging hardware 1, and a shaft 14 instead 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.

The shaft 14 is threaded and is adapted 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 oscillation suppression 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 pull the stopper 12 away from the insertion member 2, thereby releasing the suppression of oscillation of the insertion member 2.

When attaching another hanging hardware 1B to the long hole 31a on the top surface of the aluminum frame 31, first move the nut 13 and stopper 12 upward and insert the insert member 2 into the long hole 31a in a tilted (upright) state. Next, after adjusting the posture of the insert member 2 to be horizontal so that it is aligned with the aluminum frame 31, lower the stopper 12 to a position where it comes into contact with the insert member 2 to prevent it from swinging, and then lower the nut 13 to abut against 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.
