10 may be locked to the locking rod 21 attached to the
(B)). Conventionally, since there was no such temporary support means, it was very difficult to lock the heavy work A to be coated.

Once the upper side of the workpiece A is locked by the locking rod 21 mounted on the long rotating member 7, the locking rod 21 mounted on the long sliding member 13 can be freely moved. The lower surface of the object A can be held by using the locking rod 21 to fix the object A (FIG. 10C). In this case, the rotating long member 7 is not rotated. The advantage of providing the locking rod 21 on the sliding long member 13 is shown in FIG.
The invention is not limited to the one shown in FIG. For example, when the object to be coated A has a large dimension in the vertical direction, it can be dealt with by attaching the locking rod 21 to the lower end portion of the sliding long member 13. This is not possible with a conventional workbench for painting which does not have the sliding long member 13.

The mounting mode of the locking rods 21 is not limited to the embodiment, and for example, the three locking rods 2
1 may be provided on the rotating long member 7, and one locking rod 21 may be provided on the sliding long member 13. The number of locking rods 21 is not limited to four in the embodiment, and may be, for example, three or five. Further, in the embodiment, the locking rod 21 and the long members 7 and 13 are each formed of a long member having a square cross section, but the shape is not limited to this. It may be circular.

FIG. 11 shows another embodiment of the sliding long member 13, in which the sliding long member 130 is

When the sliding long member 130 is not provided,
a, and if it is moved downward along 1b,
When the object to be coated is rotated, the sliding long member 1
30 does not get in the way. The means for mounting the sliding long member 130 and the column 1a1b is, for example, the sliding long member 13
Means 140 and 150 similar to the means in can be adopted. Further, in order to prevent the sliding long member 130 from moving downward due to the object to be coated and its own weight, a plurality of locking holes are provided in the length direction of the columns 1a and 1b. Alternatively, a locking pin may be engaged.

FIG. 12 shows another embodiment of the stay-2. The stay-2 is made up of a cylindrical first member 2a and a first member 2a.
And the second member 2b slidable and position-fixable with respect to the hollow portion, the length of the stay -2 can be adjusted in the length direction. Therefore, by adjusting the length of the stay-2, it is possible to change the interval between the column 1a and the column 1b. In the illustrated state, the case where the interval between the columns 1a and 1b is narrow (the case where the length of the stay -2 is short) is shown, and the receiving portion 15 of one sliding long member 13 is the first member 2a.
The receiving part 15 of the other sliding long member 13 is attached to the second member 2b. In this state, the rotation elongate member 7 has left an extra length (left end in the figure).
By increasing the length of the support 1a with respect to the support 1b
Can be separated.

By making the length of the stay-2 variable, the length between the columns 1a and 1b can be changed, and the length can be changed according to the size and shape of the workpiece to be locked. The work bench can be installed in a well-balanced manner. Further, for example, when changing the position of the sliding long member 13 corresponding to the object to be coated, by moving the position of the column 1b correspondingly, it is possible to balance the whole center of gravity and to work more. The object to be coated can be locked in an easy state.

[0031]

According to the first and second aspects of the present invention, the plurality of locking rods can be selectively and appropriately mounted on arbitrary portions of the rotating long member and the sliding long member. Therefore, it is possible to flexibly cope with the type of the object to be coated. In addition, the use of the rotating and sliding long member can provide strength to the frame body of the workbench, and can endure well even when the object to be coated is heavy. .

The third aspect contributes to space saving during storage. Claim 4
