Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a spray stand for holding a work during painting, and particularly to an improvement of a spray stand suitable for painting vehicle parts on a vehicle sheet metal. Is.

"Prior Art" Conventionally, as a spray stand of this type, a dedicated spray stand is prepared for each work in a mass production plant, or a spray that moves by computer control while suspending and moving the work. Although it is designed to paint with a gun, there is no spray stand that can handle cases where the shape and size of each work is different, such as in an automobile sheet metal factory. It leans against the ceiling, hangs it from the ceiling, or puts a "leveling pad" on the floor or workbench to adjust the level so that each work is supported in a state suitable for each painting.

[Problems to be solved by the device] Therefore, in a large variety of small amount painting work, most of the painting work is spent to support the work in a state suitable for painting, and this support is required. If it is not in an appropriate state, uneven coating or the like may occur, so that there is a drawback in that a skilled person must take careful time to support the work.

Further, this type of work is often a heavy object such as an automobile door or bonnet, and has a drawback that the labor of the operator is very large.

[Purpose] Therefore, the present invention has been made in view of the above-described drawbacks, and it is possible to hold works of various shapes and sizes in an optimal state for painting with one machine, and it is also convenient for handling heavy objects. Its aim is to provide a stand for simple spraying.

Further, in view of the fact that the present invention has a tendency that an automobile sheet metal factory does not have enough working space for entry of a large vehicle, etc., the storage can be made compact, and in addition to the detached parts when painting the vehicle, It is an object of the present invention to provide a spray stand that can be used for multiple purposes such as a step since it requires painting work at a high place such as the ceiling outer surface of the main body.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the structure of the present invention based on the above-mentioned utility model registration claim is based on the above-mentioned object, and a pair of parallel main arms are provided on the base 1.

A pair of bodies 6 connected to each other, and the base ends of the parallel second arms 6a and 6b of the second frame 6 are pivotally attached to the inner portions of the parallel main arms 2a and 2b by axes P4 and P4, respectively. Parallel third arm 8a of
8b and the horizontal crosspiece 2 connecting the parallel third arms 8a, 8b
3 is connected to the other end of the base 1, and the third frame 8 is connected to the other of the first frame 2 and the second frame 6. One of the second frame body 6 and the third frame body 8 is provided with a first hook 17 that detachably engages the first frame body 2 and the second frame body 6 in a folded state. Is provided with a second hook 20 that detachably engages the second frame 6 and the third frame 8 in a folded state, and the third frame 8 has a substantially L shape. The one end side hook bars 30 and 30 having the front end portions serving as hook portions 32 that are locked in the holes H of the work M are inserted into the front end openings of the parallel third arms 8a and 8b, and the parallel first arms 8a and 8b are inserted. Fixed screw 1 provided on the peripheral surface of the distal end side of the three arms 8a, 8b
It is fastened at 0 and 10 and is detachably connected. Further, one of the horizontal rails 7, 21 and 22 of the second frame body 6 has a substantially linear rod-like end portion which engages with the hole H of the work M. The other side hook bar 40, which is a hook portion to be stopped, is attached to the cross rails 7, 21, 2,
A holding member 18b having a through hole 18c for penetrating the other side hook bar 40 is continuously provided on a rotary base member 18a which is rotatably arranged around the holding member 1.

"Operation" Next, the operation of the present invention will be described with reference to the accompanying drawings.

First, the state shown in FIG. 1 shows the usage form as a workbench, stepping board, and drying stand. The usage example as a workbench is the first.
As shown in Fig. 2, a flat work is placed on the second frame 6 (not visible in the same figure), and painting work is performed as shown in the figure. Can perform sheet metal work. The first example of use as a step is
As shown in FIG. 1, when a person rides on the second frame 6 to perform work such as painting at high places, and when it is used as a drying stand, as shown in FIG. It can be used by hanging dry things such as washed mats.

In contrast to the above, FIGS. 5 to 7 show the basic usage pattern, and the process of changing from the state shown in FIG. 1 to this basic usage pattern will be described. First, from the state shown in FIG. While slightly lifting the tip side (left side in FIG. 1) of the third frame 8
Is rotated in the direction of the arrow A1 to move the third frame body 8 into the second frame body 6
The second hook 20 holds both of them. Next, the folded second frame body 6 and third frame body 8 are both rotated in the direction of arrow A2 to be folded over the first frame body 2, and the second frame body is engaged by the first hooks 17, 17. Stop. At this time, the third frame body 8 has its base end portion with the axes P4 and P4 parallel to the parallel main arm 2.
Since the width is smaller than the width of the first frame body 2 by being pivotally attached to the inner portions of a and 2b, the first frame body 2 and the second frame body 6 overlap and the third frame body 8 is the second frame body. It overlaps with the frame 6 and is housed in the first frame 2. Then, as shown in FIG. 5, the work M (small door panel without a window frame of the vehicle in FIGS. 5 to 7) is inserted into the existing hole H provided on the inner surface of the work M on one side. The hook portions 32, 32 of 30, 30 are engaged and hooked.

In the above-mentioned state, the work M has a function of being supported so that it can be sprayed on the entire surface thereof, but if the work M is large, the stability is poor, and the inner surface side of the work M (the work M of FIG. The coating on the lower part on the right side), especially on the inner side, is the first frame 2, the second frame 6, the third frame 8 (hereinafter, these three frames are collectively referred to as the "first frame 2 etc."). .) May be difficult to work because it interferes. Therefore, in such a case, the other side hook bar 40 is used, and as shown in FIG.
Stability can be maintained by fixing. That is, the other side hook bar 40 is inserted through the connector 18, and its tip hook portion (not shown, the tip end of this hook bar 40 has a hook portion similar to the hook portion 32 of the one side hook bar 30). Is engaged with an existing hole H at a place different from the above, and the connecting tool 1 of the other hook bar 40 is connected.
Adjust the amount of protrusion from 8 and fix. Further, by changing the protrusion amount of the other side hook bar 40 (changing the pushing amount of the other side hook bar 40 from the connecting member 18), the holding angle of the work M can be changed, and as shown in FIG. If it is inclined, it has the effect that it can be maintained in a state where it can be easily sprayed to the lower portion on the inner surface side. Although not shown in the figure, the work M can be held in a horizontal state by further increasing the protrusion amount of the hook bar 40 on the other side as compared with the state shown in FIG.

Next, when holding a heavy object, as shown in FIG.
First, when engaging the one-side hook bars 30, 30 with a work M (a large door panel with a window frame of a vehicle in FIGS. 8 and 9) leaning against a wall or the like, the first frame body 2 or the like is moved forward ( The standing support frame 3 is tilted in the direction in which the standing support frame 3 engages with and disengages the base 1. Then, when the one-side hook bars 30, 30 are engaged with the hole H of the work M, the first frame 2 or the like is moved to the arrow A4 in FIG. 8 while lifting the work M.
Since the work M can be held by rotating the work M in the direction, the heavy-duty work M can be easily sprayed by one operator by attaching the other side hook bar 40 as shown in FIG. It has the effect of maintaining the state.

In addition, in order to change the basic use form to the storage form as described above, as shown in FIG. 14, if the first frame body 2 and the like are tilted forward, the first frame body 2 and the like are erected from the standing support frame body. 3 is the first
As shown in FIG. 5, since it is flatly laid on the base 1, it has a compact shape, and in this state, if it leans against a wall or the like, it does not occupy a large storage space.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the drawing, reference numeral 1 denotes a base, and the base 1 may have an appropriate shape, but in the illustrated example, a rectangular frame is used, and the lower surface thereof is provided with rolling wheels 25 at four corners for movement. It's easy to do.

A pair of parallel main arms 2 are mounted on the base 1.
A first frame body 2 configured by pivoting the lower ends of a and 2b on axes P1 and P1 is connected so as to be able to move up and down. Although the first frame 2 may be composed of only a pair of parallel main arms 2a and 2b, it has a horizontal rail 14 in the illustrated example, but it is disposed on the horizontal rail 14 and the horizontal rail 14. A description of the first hook 17 will be given later.

Then, the upper ends of the first frame body 2 are fixed to both main arms 2
The abutment frame body 3 composed of a pair of locking arms 3a and 3b, which are pivotally connected to the shafts P2 and P2 in the middle of a and 2b, respectively, and whose lower ends are locked to one end side of the base 1, and the base end portions. Main arm 2
A pair of parallel second arms 6a and 6b pivotally attached to the upper ends of a and 2b by axes P3 and P3, respectively, and the parallel second arms 6a and 6b.
The second frame body 6 composed of the horizontal crosspieces 7, 22, and 21 connecting the spaces is connected.

In the standing support frame 3, the lower ends of the locking arms 3a and 3b are connected by a horizontal rail 4, and the horizontal rail 4 engages with stopper projections 24, 24 provided on one end side of the base 1. The first frame 2 is not vertical, and the upper end side is slightly inclined rearward (rightward in the first figure). In the illustrated example, the upright support frame 3 is detachably engageable with the hooks 5 and 5. When the horizontal rail 4 engages with the stopper projections 24 and 24, the horizontal protrusions 4 and 5 can be detachably engaged. The crosspiece 4 is automatically engaged, and when the foot pedal 19 is stepped on, the engagement can be detached and attached. This concrete constitution is shown in FIG. 2 by a bearing 51 fixed to the machine base 1. One end of the pedal pedal 19 is fixed to a rotatably supported hook shaft 52, the hooks 5 and 5 are fixed to both ends of the hook shaft 52, and a spring 53 is hung on the pedal pedal 19. The hooks 5 and 5 are urged so as to rotate in the direction in which the hooks 5 and 5 are engaged with the horizontal crosspiece 4 (the tip end rotates left in FIG. 2).

The hooks 5 and 5 are for preventing the first frame body 2 from falling down to the left side in FIG. 1, so that the first frame body 2 is tilted to the right side in FIG. If set to, it can be omitted. Although not shown in the figure, in the present embodiment, coil springs are attached to both ends of the hook shaft 52 so that the hook shaft 52 is biased in the counterclockwise direction in FIG. However, either one of the coil spring and the spring 53 may be omitted.

The upright supporting frame 3 is pivotally attached to the shafts P2 and P2 by fixing the bearing body P in the middle of both the main arms 2a and 2b and arranging the bearing body P at a right angle to the main arm 2a. P2 passes through a through hole (not shown) provided at the upper end of the locking arm 3a, and the locking arm 3a folds in parallel with the main arm 2a from a state in which both lower ends of the main arm 2a and the locking arm 3a are opened. Although the bearing body P is pivotally attached as described above, it is needless to say that the bearing body P may be fixedly provided on the upper end side of the locking arm 3a.
The pivot connection by the structure is almost the same as above.

Further, in the illustrated example, three lateral rails 7, 22, 21 of the second frame body 6 are arranged at regular intervals, but the number and the interval may be appropriately selected. The second frame body 6 is pivotally attached to the first frame body 2 by axes P3 and P3 so as to be rotatable by 180 degrees.

I am doing it. The base ends of the parallel third arms 8a and 8b are connected to the parallel main arms 2a and 2 by the tips of the parallel second arms 6a and 6b.
The parallel third arm 8a, which is pivotally attached to the inner part of b,
The distance between 8b is smaller than the distance between the parallel main arms 2a and 2b so that the third frame 8 is housed in the first frame 2, and the parallel third arms 8a and 8b are directly connected to each other. The parallel second arms 6a and 6b are not pivotally attached to the tip portions thereof, but are pivotally attached to the horizontal rails 7 connecting the two parallel second arms 6a and 6b. 6
A bearing body (not shown) that bends inward may be fixedly mounted on a and 6b. Further, in order to enable the tip to be locked to the other end side of the base 1, a similar one to the stopper protrusion 24 may be provided on the base 1, but in the illustrated embodiment, Receiving portions 11 and 13 are provided below the frame of the base 1, and the receiving portions 11 and 13 and the inner surface of the frame engage the tip of the third frame.

The first frame 2 and the second frame 6 are detachably locked to either one of the first frame 2 and the second frame 6 in a state where the first frame 2 and the second frame 6 are folded. A second hook 20 for removably locking 17 to either one of the second frame 6 and the third frame 8 in a state where the second frame 6 and the third frame 8 are folded. Is provided.
