munnion

16,17.

This balance block 40 makes the length of balance block elongated on the whole, loads easily, and is not only safer, and can win the weight of balance block.

The 2nd example

The bob-weight of the present invention's the 2nd example is described below with reference to Fig. 5.In addition, add identical Reference numeral, omit its detailed explanation for the inscape identical with Fig. 1 of the 1st example.

The 2nd example is for for example being divided into 1 balance block of growing crosswise 50 as shown in Figure 6 the example of 3

piece

50a, 50b, 50c.

Each

piece

50a, 50b, 50c for example form

groove

51,52 in the left and right side of the piece 50b that hits exactly, side at the piece 50a of end forms the lug boss 53 that is fitted in the groove 51, equally form the lug boss 54 that is fitted in the groove 52 in the side of the piece 50c of end, concavo-convex chimeric mutually by making, can be assembled into a balance block of growing crosswise 50.

In addition, each

piece

50a, 50b, 50c are screwed into handle 55 in the tapped bore 56 like that by shown in the image pattern 7 (a), can load and unload ground mounting knob 55.

When in the framework of bob-weight 10 that balance block 50 is packed into, as long as handle 55 is installed on each

piece

50a, 50b, the 50c, on holds handle 55 was loaded into every, a balance block was just passable as being assembled into as shown in Figure 6.Because handle 55 is in the way when piling up balance block 50, therefore after packing into, take off handle 55.

By like this a balance block of growing crosswise 50 being divided into

piece

50a, 50b, 50c, be that unit handles with the piece, the operation of can packing into safely, total weight can not reduce yet.

Other embodiment of Fig. 7 (b) expression balance block.Balance block 50 shown in this Fig. 7 (b) is wholely set the handle 57 as handle on each

piece

50a, 50b, 50c.At this moment, each

piece

50a, 50b, 50c form depressed part 58 in the above, and handle 57 is fixed across these depressed part 58 ground.If handle 57 is installed like this, handle can not become obstacle when piling up.

In addition, be divided into the example that three piece constitutes a balance block, singly be not limited thereto, also can be divided into 4, be divided into 5 though above example is served as reasons.

And each piece both can constitute with mo(u)lding, also can fill concrete moulding in chase as the 1st example.

The 3rd example

Fig. 8 represents the bob-weight of the present invention's the 3rd example.

The 3rd example has added central mullion 59 in the mount structure of bob-weight 10.This central mullion 59 and

munnion

16,17 are configured in the centre of

munnion

16,17 abreast.The cross section of

munnion

16,17 is " コ " word shape, and central mullion 59 use cross sections are the section bar of " H " shape.

By being provided with central mullion 59 like this, can pile up the small-sized balance block 60 of 2 row side by side.At this moment, the length of balance block 60 is half of the balance block length of growing crosswise usually.

If adopt the bob-weight 10 of said structure, become half owing to compare the weight of each balance block 60 with the common balance block of growing crosswise, therefore handle becoming easily, even and clip finger and also can not make finger injuries, can carry out loading operation safely.And because not change of the total weight of balance block on the whole, therefore can keep total weight can realize safety again.

In addition, also can make the thickness of each balance block 60 thinner.If like this, because the weight of each balance block 60 is lighter, though therefore stacked piece number increases, loading operation becomes safer owing to the weight of balance block 60 lightens.

The 4th example

The bob-weight of the present invention's the 4th example is described below with reference to Fig. 9, Figure 10.

The 4th example makes balance block become big for opposite with the 3rd example that has increased cargo-carring balance block quantity, bears the example of total weight with 3～5,6 balance blocks.

As shown in Figure 9, the balance block 62 of 3 lengthwises is along laterally carrying on bob-weight 10 side by side.3 balance block 62 usefulness transoms 63 are fixed in the munnion 16,17.If the total weight of present embodiment balance block is for example 300kg, a balance block 62 is 100kg.In addition, Figure 10 is the example of 3 balance blocks 62 arranged side by side up and down.

If adopt the bob-weight of said structure, handwork is loaded because the preponderance of 1 balance block 62 can not be chosen, and therefore uses hoisting crane to load.Can avoid the danger of handwork thus indirectly, clip the danger of finger etc. when for example avoiding piling up balance block.

The Heavy Weight of each balance block 62 is to degree that can not a dead lift in this example, and is the weight that just can keep total weight with several, is specially 50～200kg.
