DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling workbench. In particular, the present invention, when assembling electrical equipment and the like by assembly work, put the articles to be assembled on this work table, the operator moves the work table by hand, and travels between the workers, during which necessary work is performed. It relates to a workbench used for performing one after another.

[0002]

2. Description of the Related Art A traveling worktable is one in which a baseplate can be moved along a rail on a top plate supported by legs, and several types have been already proposed.

Japanese Patent Application Laid-Open No. 9-57664 proposes a traveling work table in which a rail is directly fixed on a top plate of a work table, and an operator manually moves the base plate along the rail. ing. There, there are two first
A spur and two second spurs are attached, of which the first spur is a normal caster, which rolls on the top plate of the work table, while the second spur is A roll that is to be rolled on the rail and that is fixed in a state where two rolls are closely inclined so as to sandwich the rail is used.

In this proposal, a special structure is used in which two rolls are fixed to the second leg in close proximity to each other, so that the structure of the worktable is complicated and inexpensive. In addition, since the rails are directly fixed on the top plate of the work table, the rails are obstructed when the base plate is not used, so that it is difficult to use as a normal work table.

Japanese Unexamined Patent Publication No. Hei 11-188544 discloses that several types of base units having different rail arrangements are prepared in advance on a top plate of a work table, and the combination of the base units is changed so that different traveling routes are provided. It proposes making a traveling workbench. Here, a rail is fixed directly on the top plate of the work table to travel the base plate to form a travel guide path, while the base plate is provided with four casters of a two-wheel structure on its lower surface, and two of them are provided. The rail is sandwiched between the two wheels of the casters, and the base plate is advanced along the rail.

However, in this traveling method, the rail is directly fixed on the top plate of the work table, so that the rail becomes an obstacle when the base plate is not used, so that it is inconvenient to use it as a normal work table. . Further, in this traveling method, it is necessary to attach four wheels of a two-wheel structure, which complicates the structure of the traveling work table, which makes the traveling work table expensive, and in addition, the traveling work table has to be connected to the rail and the two-wheel casters. The creaking between them is large, so that it is difficult to smoothly advance the base plate, and there is a problem that it becomes more difficult to run more smoothly where the rail is curved.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a traveling workbench free of the above-mentioned problems. That is, when it is not necessary to use the base plate, the rails can be removed and used as a normal table, and the structure is simple and can be provided at a low cost, and the operator can smoothly move the base plate to a desired position by hand. An object of the present invention is to provide a traveling workbench that can travel.

[0008]

According to the present invention, the rail is not directly fixed on the top plate of the work table. Instead, since the work table is usually provided with a column projecting upward from the table, the rail is detachably attached to the column. Further, in order to advance the base plate along the rail, it is simple to simply attach two U-shaped pieces sandwiching the rail to the lower surface of the base plate at intervals. In addition, at least three free casters are attached to the lower surface of the base plate in order to facilitate the movement of the base plate on the top plate of the table. The present invention provides a traveling workbench having a simple structure thus produced.

According to the present invention, in a traveling worktable in which a base plate moves along a rail on a top plate of a work table, a rail can be detachably attached to a support standing upright from the top plate, and the rail can be attached to the support plate when it is attached. , And at the lower surface of a rectangular quadrilateral plate, along with one side, two locking pieces are attached at an interval, and at least three free casters are attached to the lower surface, and the free casters are provided. The lower end of the locking piece is made to protrude more than the lower end of the locking piece to form a base plate, and each locking piece has a gap just between the two projecting pieces forming the above-mentioned rail so that the rail is just inserted. Opening, placing the base plate on the top plate of the work table and placing the rail in the opening of the locking piece, the locking piece accommodates more than half of the rail height in the opening. It is intended to provide a traveling work table.

One embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a partially cutaway perspective view of a traveling workbench according to the present invention. FIG. 2 is a partially cut-away enlarged perspective view of the traveling workbench according to the present invention. FIG.
Indicates a base plate that can be used in the present invention,
(A) is a bottom view of a base plate, (b) is the same side view. FIG.
1 is a partially cutaway vertical sectional view of a traveling workbench according to the present invention. FIG. 5 is a plan view showing a connection state of the traveling workbench according to the present invention.

As shown in FIGS. 1 and 2, the traveling workbench according to the present invention comprises a work table 3 on which a leg 1 supports a top plate 2, and a base plate 4 having a rail 5 It is a traveling workbench that travels along. The column 6 stands upright from the top plate 2, and the rail 5 is detachably supported by the column 6. The rail 5 extends parallel to the top plate 2 when supported by the column 6.

The base plate 4 is, as shown in FIGS.
On the lower surface of the right-angled quadrilateral plate 7, two locking pieces 8 are provided at intervals along the one side 71, and at least three, in the figure, four free casters 9 are provided on the lower surface. By being made. In this case, the lower end of the free caster 9 protrudes more than the lower end of the locking piece 8. Each locking piece 8 is a pair of two protruding pieces standing upright from a rectangular quadrangular plate 7, and has a leading end opening downward with a gap G just enough to insert the rail 5. .

When the base plate 4 is placed on the top plate 2 of the work table 3 and the rail 5 is inserted into the distal end opening of the locking piece 8, FIG.
As shown in (1), the locking piece 8 accommodates at least half of the height of the rail in the opening. Thus, the traveling workbench according to the present invention is made.

The mechanism by which the rail 5 is removably attached to the column 6 is shown in FIG. 2 and more specifically in FIG. That is, the rail 5 has an L-shaped rail receiver 11.
Is attached to the column 6. Rail support 11
As shown in FIG. 2, the iron piece is bent into an L-shape, and a total of four locking portions 112 are provided on both sides of one piece 111 of the L so as to face outward. The other piece 113 is provided with a hole 114 for fixing a rail. Each locking portion 112 has an L shape,
Each has a dent that opens toward the direction in which the other piece 113 exists.

As shown in FIG. 2, the column 6 is formed by bending a strip-shaped iron plate so that its cross section is square, and each corner has slits 61 and 6 extending in the longitudinal direction.
2 is provided. The interval between the slits 61 arranged in the longitudinal direction is equal to the interval between the locking portions 112 in the rail receiver 11. Therefore, one piece 111 of the rail receiver 11
Is brought into contact with the column 6 and the locking portion 112 is inserted into the slit 61 of the column.
And 62 and pushed downward, the lower edge of the slit cuts into the recess of the locking portion 112 as shown in FIG. At this time, since the width of the depression of the locking portion 112 is made equal to the thickness of the iron plate forming the column 6, the rail receiver 11 is fixed to the column 6.

The other piece 113 of the rail receiver 11 is formed by bending an iron piece into a U-shaped cross section, and has a hole 114 at the center. This hole 114 is for fixing the rail,
As shown in FIG. 2, the rail 115 is fixed to the rail 5 by fitting a screw 115 into the hole 114 and fixing the tip of the screw 115 to the rail 5. It goes without saying that the diameter of the screw 115 is smaller than the width of the rail 5.

The rail receiver 11 can be removed from the support 6 by lifting the rail receiver 11 and removing the locking portion 112 from the slits 61 and 62 of the support 6. Thereby, the rail 5 can be removed from the work table 3. Therefore, the rail is detachable from the work table.

The right-sided quadrilateral plate 7 constituting the base plate 4 has a rounded corner in the example shown in FIG. A rounded corner may not be strictly a right-angled quadrilateral, but it is assumed here that it is included in the right-angled quadrilateral. The corners are rounded to prevent the corners of the base plate from hitting strongly when rotating the base plate by 90 or 180 degrees.

In the example shown in FIG. 3, the rectangular plate 7 is made hollow by bending an iron plate. The entire upper surface of the plate 7 is made of a single iron plate 70 in a shallow box shape, and after attaching a lower plate, a part of the side wall is further bent inward to form a folded piece having a U-shaped cross section. are doing. In contrast, plate 7
Is formed of three lower plates 73, 74 and 75, all of which are formed in a shallow box shape and are welded to the iron plate 70.

The plate 7 has two locking pieces 8 along one side 71.
Is attached. Each of the locking pieces 8 is formed by bending a metal bar into a U-shape. The locking piece 8 is fixed to the plate 7 by welding with its central piece inserted into the plate 7 and only the two side pieces protruding from the lower plate 75. Therefore, plate 7
When viewed from the lower surface side, each locking piece 8 breaks through the plate 75 and only two protruding pieces appear to stand.

The gap G at the tip of the two protruding pieces is a gap just enough to insert the rail 5. If the gap G is larger than the width of the rail, the base plate 4 will rattle on the rail 5 when the base plate 4 is moved along the rail 5.
This gap G must be as narrow as possible. Also, 2
The locking pieces 8 need to be provided on the plate 7 with a gap. If the gap is small, the base plate 4 tends to rattle largely on the rail. Conversely, if the gap is wide, it tends to be difficult to move along the rail where the rail is curved. Therefore, it is preferable that the two locking pieces 8 are provided at positions symmetrical with respect to the center on one side 71 and provided at a position separated from the center by one third to one sixth of the length of one side.

When the base plate 4 is placed on the top plate 2 of the work table and the rail 5 is inserted into the gap between the two projecting pieces of each locking piece 8, the gap between the locking pieces 8 is It is necessary to accommodate at least half of the height. Among them, as shown in FIG. 4, the tip of the locking piece 8 is preferably located below the center axis of the rail 5 and above the lower end of the rail 5. By doing so, it becomes easy to insert the rail 5 into the gap G between the locking pieces 8 and to easily engage the base plate 4 with the rail 5. Conversely, the base plate 4 is lifted and the base plate 4 is 5 can be easily released from engagement. In addition, at the time of engagement, if the position where the locking piece 8 is provided is marked on the upper surface of the base plate, the engagement with the rail 5 is easy.

The base plate 4 is provided with a swivel caster 9 in addition to the engaging piece 8. The universal caster is a caster having a mechanism that can freely change the direction in which the wheel rotates and moves. The swivel casters 9 need to be distributed over the entire rectangular plate 7. It is necessary to provide at least three free casters 9, and it is preferable to provide four.

As shown in FIG. 5, the traveling work table according to the present invention has a work table on which linear rails 5 are arranged and a work table on which a rail 51 curved in a quarter circle is arranged. By connecting to the table, it is possible to make the base plate travel along a course that is bent in an L-shape as a whole. By connecting a work table on which a rail curved to a quarter circle is further arranged, the base plate can be advanced along a U-shaped or Z-shaped course.

The work table used in the present invention requires a support standing upright from the top plate, and the support is preferably an extension of the work table leg. It is desirable to use an integrated one. Therefore, as shown in FIG. 5, when the work tables are connected one after another, the work table to be connected later shares the legs and the columns of the work table assembled earlier. It is preferable that the connection be extended one after another by connecting one top plate and one post on one side to the work table assembled earlier.

[0026]

In the traveling workbench according to the present invention, the base plate is provided with three or more free casters 9, and the tip of the free casters 9 projects more than the locking piece 8.
When the base plate 4 is placed on the top plate 2, three or more free casters 9
Comes into contact with the top plate 2, so that the base plate 4
In this way, the vehicle can run in a stable state. Moreover,
Since the locking piece 8 sandwiches the rail 5, the base plate 4 is forced to travel along the rail 5. In particular, since the locking piece 8 accommodates at least half of the height of the rail 5 in the opening, even if the base plate 4 is slightly inclined, the locking piece 8 does not come off the rail 5, so that the locking piece 8 is surely provided. The base plate can be run along the rail. Also, the engagement with the rail can be released by the locking piece 8 of the base plate 4 lifting the fringe edge, so that the base plate 4 can be easily removed.

Further, according to the present invention, the base plate 4 can be easily removed from the rail 5 as described above, and the rail 5 is removably attached to the column 6, so that the rail 5
, It is easy to make the work table without rails, and thus it is easy to use the work table as a normal work table without rails. Further, in the traveling work table of the present invention, the required rail receiver, rail and base plate are all simple in structure, so that they can be easily manufactured and can be provided at low cost. The present invention has such advantages.
