A tension spring (19) is stretched between the lower spring mounting portion (24) and the lower spring mounting portion (24) provided in the vicinity of the lower spring mounting portion (24). Has been granted. When the operating ring (18) is pulled and the operating lever (17) is turned clockwise in FIG. 1, the upper pivot shaft (9)
Will fall to the right side beyond the operating fulcrum (21). This results in the state of FIG. Thereby, the tension spring (19) contracts, and the link mechanism (4) is loosened as shown in FIG. Conversely, as shown in FIG. 1, when the operating ring (18) is pulled counterclockwise and the tension spring (19) is positioned to the left of the operating fulcrum (21) (the state of FIG. 1), the upper spring mounting portion (20) and the tension spring (19) act between the lower spring mounting portion (24),
The link rod (7) is pulled up, and the movable pad (15) projects toward the fixed pad (16). An inverted cover member (3) is attached from the outer surface side of the mechanism side leg (1b) to the lower end, and the upper end of the cover member (3) is pivotally connected to the operating fulcrum (21). Is being worn. The distal end (3a) of the cover member (3) projects from the distal end of the mechanism-side leg (1b), and further has the distal end (3a) and the outer surface (3c).

6) Tensile force is applied to project to the side. Cover material
A projection (3b) protrudes from the inner surface of the outer wall (3c) of (3). As shown in FIG. 2, the projection (3b) is used to push the cover member (3) rightward in the figure, and the operating ring (18) is pulled clockwise to rotate the swing lever (3). When the lower end of 30) protrudes to the right in FIG. 2, the protrusion (3b)
To the cover member (3) on the right side (that is, the fixed side pad).
(In the direction away from (16)). Next, the operation of the first embodiment of the present invention will be described. As shown in FIG. 2, when the operating lever (17) is pulled clockwise, the operating lever (17) is moved to the operating fulcrum (21).
Clockwise around the lever, which causes the actuating lever (1
The upper end of the swing lever (30) connected to the other end of (7) moves together with the trajectory of the swing lever pivot shaft (22), and the lower end of the swing lever (30) moves to the right in the figure. , Cover member as described above
The cover member (3) comes into contact with the projection (3b) of (3) and is pushed out in a direction away from the fixed pad (16). At this time, the cover spring (25) is extended. Projection of swing lever (30)
Since the pressing force on (3b) is given by the tension of the tension spring (19), the tension of the extended cover spring (25) is set to be smaller than the tension of the contracted tension spring (19). Have been. In FIG. 2, the cover member is pushed to the right.
In the present embodiment, the distal end (3a) of (3) is moved to a position substantially coinciding with the distal end of the mechanism-side leg (1b).
The link rod (7) is pulled down with the contraction of the tension spring (19), the upper link plate (5) rotates counterclockwise around the upper fulcrum axis (8), and the suspension ring (6) is connected to the clamp body (1). ). On the other hand, as can be seen from FIG. 2, the movable pad (15) moves downward of the link rod (7) and the lower link plate (12) rotates clockwise around the lower fulcrum axis (13). To the mechanism side leg (1b) side (in other words, the direction away from the fixed side pad (16)), and move to the fixed side pad (1
6) and the movable pad (15) are widely opened.
At this time, since the movable pad (15) and the tip of the mechanism side leg (1 b) and the tip of the cover member (3) are almost aligned,
There is no hindrance when inserting the lifting member (T) into the member insertion recess (1d). After the lifting member (T) is inserted into the member insertion recess (1), the operating ring (18) is pulled up counterclockwise as shown in FIG. It rotates counterclockwise around the operating fulcrum (21) and pulls up the swing lever (30). The tension spring (19) extends with the counterclockwise rotation of the operating lever (17), and pulls up the link rod (7). At this time, by moving the operating fulcrum (21) to the left side in the figure, even if the tension spring (19) releases the hand from the operating ring (18) due to click motion, the operating lever (17) moves clockwise. There's no going back. Operating lever (17)
Comes into contact with the stopper (31) and stops. When the link bar (7) is pulled up by the tension spring (19), the lower end of the swing lever (30) also moves to the left in FIG. 1 in accordance with the movement of the operating shaft (23) of the link bar (7). Then, it is separated from the protrusion (3b) of the cover member (3). This causes the cover member (3) to move toward the fixed pad (16) due to the tensile force of the cover spring (25). In addition, the upward movement of the ring rod (7) causes the lower link plate (12) to rotate counterclockwise, thereby moving the movable pad (15) to the fixed pad (16). As a result, the lifting member (T) is sandwiched between the movable pad (15) and the fixed pad (16) by the spring force of the tension spring (19), and at the same time, the distal end of the cover member (3) is The gap (1e) generated between the lifting member (T) and the distal end of the mechanism-side leg (1b) comes into contact with or close to T). The pinching force between the fixed side pad (16) and the movable pad (15) at this time is not so strong because it depends only on the pulling force of the tension spring (19). Hanging ring (6) in this state
The upper link plate (5) and the upper fulcrum shaft.
Attempting to rotate clockwise around (8) will pull up the link bar (7). As a result, the movable pad (15) tries to move toward the fixed pad (16) due to the weight of the lifting member (T) and the clamp body (1), and the suspension ring (6) and the movable pad (1) move.
By 5), the lifting member (T) is strongly held. As a result, it can be lifted while holding the lifting member (T). If the lifting member (T) is lifted as described above, it will be transported to a predetermined place in that state. However, in a cluttered construction work site, during the transportation or lifting and lowering, The clamp body (1) may come into contact with obstacles such as beams and columns. Even in this case, since the cover member (3) is present, an obstacle is fitted in the gap (1e) between the tip of the mechanism side leg (1b) of the clamp body (1) and the lifting member (T). Without getting stuck
Smooth movement becomes possible. When arriving at a predetermined place and lowering the clamp body (1), the tip (3a) is formed to be inclined even if an obstacle contacts the tip (3a) during this descent. So the obstacle is the cover member
Sliding without being caught by (3), the lifting device (A) is caught by an obstacle, the lifting chain is loosened, the suspension ring (6) falls down, the link mechanism (4) is loosened, and it can move with the fixed pad (16) A situation in which the holding force of the pad (15) becomes only the tension of the tension spring (19) and loses the weight of the lifting member (T), and the lifting member (T) falls off can be avoided. FIG. 4 shows a second embodiment of the cover member (3). In this case, instead of pivoting the upper end of the cover member (3) to the operating fulcrum (21), the outer side of the mechanism side leg (1B) is used. This is an example in which a projecting portion is provided in the portion, and the cover member (3) is pivotally attached to the operating fulcrum shaft (21A). In this case, the position of the operating fulcrum shaft (21A) is
Since it comes closer to the tip of (b), the protrusion amount of the cover member (3) is smaller than that of the first embodiment. FIGS. 5 and 6 show a third embodiment of the present invention, in which a pair of inverted C-shaped lever-shaped members are connected by a connecting member to form a cover member (3). In the second and third embodiments, since the lower end of the swing lever (30) does not contact the cover member (3), in this case, the lower link plate (12) contacts the inner surface of the cover member (3). Then, the cover member (3) is pushed out in a direction away from the fixed pad (16) (rightward in the figure). FIGS. 7 and 8 show a cover member (3) according to the present invention.
In the fourth embodiment, in this case, the cover member (3) has a claw shape, and an operating fulcrum (21B) provided at the tip of the mechanism side leg (1b).
Is pivoted to. A spring hook (26b) is provided on the upper end of the cover member (3), and a cover is provided between the spring hook (26a) of the spring hook projection (12a) provided on the lower link plate (12). A spring (25) is stretched, and the cover member (3) moves along with the movement of the lower link plate (12) to support the operating fulcrum (21).
B) and rotate the cover member from the tip of the mechanism side leg (1 b).
The tip (3a) of (3) projects or retreats. As a result, the gap (1e) is closed at the tip (3a). According to the suspension device of the present invention, the cover is attached to the material mechanism side leg so as to move closer to and away from the fixed side pad with the movement of the movable side pad. Because the pad is closed between the pad and the mechanism side leg, when the building material is suspended and transported, or when moving up and down, it does not get caught even if the structure contacts the suspension side mechanism side leg. However, the building material is always held with a strong holding force during the transfer, and the building material does not fall off.
