DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a ceiling frame structure in a work table which is attached to the front and rear or one of two columns which are vertically erected from each other.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a work table (not shown) for assembling work by an operator or the like in an assembly factory or the like is appropriately arranged, for example, at an appropriate position on an assembly line. A pair of support rods 03, which are supported by the two columns 01 standing vertically apart from each other and extend above the top plate, extend forward from the top of the columns 01, and a tool is attached to the tip of the pair of columns 03. Alternatively, a horizontal rod 04 for suspending and supporting work tools, etc.
Lighting equipment such as a fluorescent lamp for illuminating the upper surface of the top plate is arranged side by side near the horizontal rod 04 to form a top end frame.

More specifically, this top end frame is slidably inserted into a pair of base rods 03a each having a predetermined length in which both support rods 03 are formed, for example, in a cylindrical shape. And a pair of auxiliary rods 03b.
Lighting equipment 05 such as the horizontal rod 04 or a fluorescent lamp is attached to the tip of 3b so as to be close to each other.

[0004] The two auxiliary rods 03b are slidably inserted and supported inside the base rod 03a so that the locking position of a tool or work tool or the front and rear position of the lighting equipment can be adjusted. Have been.

[0005]

However, the two support rods 03 configured as the above-described top end frame structure are slidably inserted and supported inside the base rod 03a. It is configured.

[0006] From this, the shortest length of the base rod 03a is:
Even if all of the auxiliary rods 03b supported by one end of the base rod 03a are accommodated in the base rod 03a, at least half of the total length of the base rods 03a and the auxiliary rods 03b when both the auxiliary rods 03b are maximized. The above needs to be secured.

When shortening both auxiliary rods 03b,
The length of contraction of the auxiliary rod 03b is limited because the mounting part of the horizontal rod 04 and the lighting fixture 05 attached to the outer periphery of the auxiliary rod 03b abuts on the tip of the base rod 03a.

[0008] For this reason, since the adjustment range of the horizontal rod 04 and the lighting equipment 05 in the front-rear direction is narrow, if a tool or a work tool is suspended and supported by the horizontal rod 04 in front of the top plate, the work is obstructed. In addition, there is a problem that not only the function as the top end frame is reduced but also the working efficiency on the top plate is greatly reduced.

The present invention has been made in view of such a problem, and it is possible to appropriately set a use area of a horizontal rod or a lighting fixture provided on a top end frame to a desired position according to a use purpose. It is an object of the present invention to provide a top end frame structure in a top plate that can greatly improve work efficiency in the top plate.

[0010]

In order to solve the above-mentioned problems, a top end frame structure in a work table according to the present invention is provided in a work table attached to the front and rear or one of two support columns vertically erected from each other. A top end frame structure, comprising: a pair of support rods extending forward from at least the top of the support column; and a holder which is slidably inserted around the outer periphery of both support rods and is movable in the front-rear direction. It is characterized by comprising horizontal bars provided at both ends, and holding means for positioning and holding the holding tool moving on the pair of supporting rods at predetermined positions of the supporting rods. According to this feature, instead of the conventional telescopic support rod, the horizontal rod is guided and moved by the pair of support rods via the holder, so that the horizontal rod moves freely on the support rod. It is possible to set the use area of the horizontal rod and the lighting fixture provided on the top end frame to a desired position as appropriate according to the purpose of use, and it is possible to greatly improve the work efficiency of the top plate.

[0011] In the top frame structure of the worktable according to the present invention, the holder is formed as a generally U-shaped opening facing outward at both ends of the horizontal rod, and the opening is formed in both support rods from the inside thereof. It is preferable that they are inserted. By doing so, since the opening is attached to both ends of the horizontal rod outwardly, the horizontal rod supported by both support rods is restrained from moving up and down, and is held until it is held by the holding means. Between the support rods.

[0012] In the top end frame structure of the worktable according to the present invention, the holding means may include a plurality of engagement holes arranged in the extending direction of the pair of support rods and the holding tool together with the holding tool. It is preferable that the engaging portion be configured with a locking portion that can be selectively engaged with the engaging hole. With this configuration, since the plurality of engaging holes are arranged in advance in the direction in which the support rod extends, the holding tool can be moved to a desired position only by selectively engaging the locking portion with the desired engaging hole. Positioning can be easily performed.

[0013] In the ceiling frame structure of the work table according to the present invention, it is preferable that a lighting device is provided between the two holders in proximity to the horizontal rod. According to this configuration, since the lighting fixture is provided near the horizontal rod, a tool or a work tool suspended and supported by the horizontal rod is illuminated, so that not only a mistake in use does not occur, but also a top plate is used. The illumination area can be appropriately adjusted according to the use position of.

Next, the top frame structure of the present invention will be described. FIG. 3 is a partial cross-sectional view showing a state where the holders at both ends of the horizontal rod are attached to the horizontal rods of both upper support members. As shown in FIG. 3, the horizontal rod 19b is a cylindrical tube, and both ends are formed to have a length corresponding to the inner dimension between the upper support members 18, and both ends of the horizontal rod 19b have cross sections. A holder 19a having a U-shape and having a predetermined length is fixed so that the opening side faces outward, and the holder 19a is selectively fixed to a predetermined position of the horizontal rod 18b by the holding means. I have.

More specifically, a single plate 19f is welded to the inside of both ends of the horizontal rod 19b, and a set screw 19g inserted from the outside through an insertion hole 19h formed in the holder 19a is attached to both single plates 19f. The holder 19a is fixed by screwing, and both ends of the lighting fixture support rod 19d are welded to the upper ends of the two holders 19a. Is equipped with a fluorescent lamp 19c as a lighting fixture.

Next, the holding means includes an engagement hole 18 having a plurality of female threads formed in the horizontal rod 18b of both upper support members 18.
g are arranged in a row, and nuts 18d are welded to the inside of the horizontal rod 18b corresponding to the engagement holes 18g, and the both holding tools 19a are inserted into the lower surfaces of both the holding tools 19a. In this state, the insertion holes 19i correspond to the respective engagement holes 18g.

In this way, the horizontal rod 19b is
9a, together with the fluorescent lamp 19c, is held movably back and forth on a horizontal rod 18b of both upper support members 18. The horizontal rod 19b has a plurality of hooks for locking work tools and tools. The stop hook 19j is slidably held in the left-right direction.

When positioning the horizontal rod 19b at a predetermined position of the horizontal rod 18b, a bolt 19e is screwed to the nut 18d through an engagement hole 18g selected from an insertion hole 19i on the lower surface of the holder 19a.

Next, when changing the front / rear position of the horizontal rod 19b, the bolt 19e is removed and the holder 19a is moved to the horizontal rod 1b.
