Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a panel hanging system in which a panel such as a wooden panel can be reliably clamped by tightening a tightening port, and the panel can be easily removed by pulling down a lever. Regarding the upper jig.

A panel lifting jig used when constructing a so-called panel house using panels such as wood-based panels is used to hold a large number of panels between a pair of clamp parts of the panel hoisting jig and lift them with a crane or the like. Since it is necessary to lift the panel and install it in a predetermined location, it must have a structure that can hold the panel without it falling off, especially for safety reasons, and a structure that allows the panel to be easily removed after it is lifted. must have.

However, in conventional panel lifting jigs of this type, for example, panel lifting jigs that clamp the panel between two clamp parts by a certain lever operation, the panel can be easily removed, but the tightening is difficult. If the force cannot be adjusted and the lever operation is not sufficient to tighten the panel, the clamp section will not be able to hold the panel sufficiently, and as a result, there is a risk that the panel will fall off during lifting. In addition, in a panel lifting jig that uses tightening bolts, the tightening force can be easily adjusted and the panel can be securely held by the clamp part, but the tightening also prevents the panel from coming off. This had to be done with bolts, which required labor to remove the panel.

The present invention has been made in view of the above-mentioned points, and it is possible to securely clamp a panel such as a wooden panel by tightening a tightening bolt, and to easily remove the panel by pulling down a lever. The present invention provides a panel lifting jig that can be used to lift panels.

That is, the panel lifting jig of the present invention has a main body having a first clamp part at the lower end, and a rotary arm having a second clamp part at the lower end, which is pivotably supported at the upper end thereof. A tightening mechanism is provided between a part of the main body and a part of the rotating arm, and the tightening mechanism tightens the panel between the first clamp part and the second clamp part. The clamping state of the clamping mechanism is released by pulling down a lever whose one end is rotatably supported on the main body, thereby clamping the first clamp part and the second clamp part. The panel lifting jig is configured to separate the tensioning mechanism from the tensioning mechanism, and the tightening mechanism includes an adjustment arm whose length can be adjusted by rotating a tightening bolt. The invention is characterized in that it does not tighten the panel by increasing the length of the constant arm.

An embodiment of the panel lifting jig of the present invention shown in the drawings will be described below.

FIG. 1 shows a perspective view of the panel lifting jig of the present invention. , 3 is a rotating arm whose upper end is rotatably supported at the upper part of the main body, and 4 is a second clamp part fixed to the lower end of the rotating arm 3 and having a spike 4" on the front surface. 5 is a lever with one end rotatably supported on the main body 1 on the right side of the pivot support 6 of the rotating arm 3; 7 is a lever that connects a part of the main body l and a part of the rotating arm 3; The panel lifting jig of the present invention is configured such that the panel is held between the first clamp part 2 and the second clamp part 4 by tightening the clamp mechanism 7. At the same time, by pulling down the lever 5, the tightening state by the tightening mechanism 7 is released, and the first clamp part 2 and the second clamp part 2 are separated.
There is no need to separate the panel from the clamp part 4 and separate the panel.

The tightening mechanism 7 includes an adjusting arm 8 whose length can be adjusted by rotating a tightening bolt 17, and by increasing the length of the adjusting arm 8, the panel can be tightened. None.

To explain the embodiment in more detail, the tightening mechanism 7 has an upper end portion of a cam portion IO1 formed integrally with the shaft support 9 of the lever 5 at the upper right side of the main body 1, as shown in FIGS. 1 and 2. A rotating rod 11 that is rotatably supported, and a rotating rod 11 that supports the left side.
A fixed arm 8 is rotatably supported on the lower end of the rotary arm 3, and the lower end of the rotary arm 3 is rotatably supported on the rotary arm 3. Line segment 1 connecting the pivot support at the upper end and the pivot support at the lower end of the adjustment arm 8
2 (shown by an imaginary line in FIG. 2), it is brought into contact with the cam portion 10 from the right side in a state of protruding to the left.

The adjustment arm 8 has a main body piece 13 whose left side is rotatably supported on the lower end of the rotating rod 11, and a two-wheeled part inserted into a fitting hole 14 provided at the right end of the main body piece 13. A sliding rod I5 is fitted into the rod and its lower end is rotatably supported on a part of the rotating arm 3.
and a tension spring 16 that connects the main body piece 13 and the rotating arm 3; and a tension spring 16 that is screwed onto the right end of the main body piece 13 from above, and whose lower end is pressed against the upper end of the sliding rod 15 by the action of the tension spring 16. By adjusting the degree of screwing of the tightening bolt 17 into the main body piece 13, the sliding rod 15 can be inserted into the insertion hole 4 of the main body piece 13. adjusting the degree, thereby substantially changing the length between the axial support 18 of the adjusting arm 8 to the lower end of the pivoting rod 11 and the axial support 19 of the adjusting arm 8 to the pivoting arm 3 However, by adjusting its length to be longer, the rotating arm 3 can be rotated clockwise in FIG. 2 to grip the panel.

Further, the clamping between the first clamp part 2 and the second clamp part 4 as described above by the tightening mechanism 7 can be released by rotating the lever 5 clockwise in FIG. This is done by pressing the lower end of 11 to the right with a cam portion 10, and the pivot of the rotation rod 11 with the adjustment arm 8 is moved to the right of the line segment 12 in FIG. At this point, the rotating arm 3 is rotated counterclockwise at once to separate the first clamp part 2 and the second clamp part 4.

In addition, the shaft support 6 of the rotating arm 3 in the panel lifting jig of the present invention allows the first clamp part 2 and the second clamp part 4 to be connected even if there is a slight difference in thickness between the panels to be lifted.
The panels can be eccentrically mounted or not, so that the panels can be clamped with their front surfaces accurately parallel to each other. That is, as shown in FIGS. 2 and 3, in the shaft support 6, an eccentric shaft 21 is integrally provided on the surface side of a shaft 20 rotatably provided on the main body 1, and the eccentric shaft 21 is rotatably provided. moving arm 3
The eccentric adjustment plate 2 is constructed by rotatably fitting the upper end portion and is integrally fixed to the surface side of the eccentric shaft 2I.
2 rotates the shaft 20 together with the eccentric shaft 21 to move the center of the eccentric shaft 21, thereby changing the pivot position of the upper end of the rotating arm 3. The pivot position of the upper end of the rotating arm 3 is fixed by using a screw 23 passed through the end of the eccentric adjustment plate 22.
This is done by screwing into one of a plurality of positioning holes 24 located around the shaft 20 and screwed into the main body l.

Further, 25 is a pivot support located in front and above the first clamp part 2 and provided on both sides of the main body 1 in a direction perpendicular to the front surface of the first clamp part 2; 26 is a pivot support for the pivot support 25 The auxiliary clamp part 26 is pivoted so as to be slidable and rotatable, and the auxiliary clamp part 26 is biased by a tension spring 27 in a direction in which it comes into pressure contact with the first clamp part 2 . This auxiliary clamp section 26 is used to clamp the end of the panel 28 between the second clamp section 4 and the second clamp section 4 when lifting a panel 28 having no width at the end as shown in FIG. is the first
It is used by being brought into contact with the front surface of the first clamp section 2, as shown in FIGS. 2 and 5.

In addition, a stopper 29 is provided on the back side of the auxiliary clamp part 26.
In order to maintain this state of contact with the first clamp part 2, the stopper 29 is fitted into a locking hole 37 in the front part of the corresponding first clamp part 2. put. When the auxiliary clamp part 26 is not in use, it is pulled upward in the direction of the second clamp 4 against the tension spring 27, as shown by the two-dot chain line in FIG. 1 and by the solid line in FIG. After rotating, the tensile force is released and the stopper 29 is fitted into the locking hole 38 in the front surface of the corresponding first clamp part 2, thereby locking the first clamp part 2 and the second clamp part. This is done so that it does not get in the way when a normal panel 30 as shown in FIG. 7 is held. Incidentally, a spike 26' is provided protruding from the front surface of the auxiliary clamp section 26, and the rear surface thereof is left blank so that the spike 26' of the first clamp section 2 does not collide with the spike 26' and get in the way.

In addition, in FIG. 2, 31 is a handle protruding from both sides of the upper end of the main body 1, and 32 is a curved guide groove bored from the left side to the upper part of the main body 1.

In addition, 33 is a chain whose upper end is suspended from a crane or the like (not shown) and whose lower end is fixed to a fitting bar 34 which is fitted into the curved guide groove 32, and is used to lift horizontally stacked panels. By moving the upper insertion bar 34 from the lower end of the curved guide groove 32 to the upper end as it is lifted, as shown in FIG. 2, it is possible to reduce the pressurizing moment at the beginning of lifting and prevent damage. It is. That is, if there is a distance between the clamp parts 2 and 4 that hold the end of the panel on one side and the position of the insertion bar 34 where the lifting blade is applied, a moment proportional to the distance is applied to the end of the panel. If the panels are stacked sideways, position the fitting hole <-34 near the clamp part 2.4, and as the panel is raised up, it will automatically fit Insert bar 3
Consideration was given to move 4. 35 is a fitting bar 3 from the upper and lower ends of the curved guide groove 33 in FIG. 2 to the upper end.
4, but prevents the insertion bar 34 from moving from the upper end to the lower end of the curved guide groove 33 by abutting against a stopper 36 protruding from the main body 1. It is supported on a shaft so that it can rotate freely.

Therefore, when using the panel lifting jig of the present invention having the above configuration, first, as shown in FIG.
It is suspended from a crane or the like via a lever 5, and an operating rope is fixed to the tip of the lever 5. Furthermore, depending on the thickness of the end of the panel to be lifted, the auxiliary clamp part 2 is installed as described above.
6 is used as necessary, and the eccentric position of the pivot support 6 of the rotating arm is adjusted as described above according to the thickness of the panel to be lifted. Next, the first clamp part 2
Alternatively, place the panel to be lifted between the auxiliary clamp part 26 and the second clamp part 4, position the lever 5 at the position shown in the figure, and bring the lower end of the rotating rod 11 into contact with the cam part 10 as shown in the figure. In addition, as described above, the panel to be lifted is placed between the first clamp part 2 or the auxiliary clamp part 26 and the second clamp part 26.
After positioning it between the clamp part 4 and the tightening bolt 17
The panel is reliably held by adjusting the length of the adjustment arm 8 by rotating it with a latch type box wrench or the like to increase the length of the adjustment arm 8 as described above. After that, the panel is hoisted to a predetermined position by a crane, etc., and the operating rope at the tip of the lever 5 is pulled down.As mentioned above, the rotating member 3 is rotated in the direction of the arrow in Fig. 2, and the clamping force of the panel is increased. can be easily released and the panel can be easily removed. Before lifting the next panel, turn the tightening bolt 17 to shorten the length of the adjustment arm 8.

As described above, according to the panel lifting jig of the present invention, the panel can be clamped by tightening the tightening bolts, which makes it easy to check the tightening condition. The panels can be lifted safely without falling off, and the clamping of the panels can be released all at once by pulling down the lever, which has the great effect of making it easier to remove the panels.
