Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a table for excavation table in which the area of the top plate is variable.

[Conventional technology]

Recently, there has been proposed a digging tray in which the size of the digging tray can be changed according to the number of users.
FIG. 2 is an exploded perspective view showing the outline of this excavated turret.
In FIG. 2, reference numeral 1 is a sitting table, on which legs 3 are placed on the upper surface of a stile 5 arranged at the periphery of an opening provided on the floor. This table 1 is a pair of main top plates that can be separated in the direction of expansion and contraction.
2,2, the legs 3 attached to these main top plates 2,2, and the auxiliary top plate 4 which is sandwiched and held between these main top plates 2,2 in a separated state. Become. The auxiliary table 4 is folded and stored on the lower surfaces of the main tables 2 and 2 when the table 1 is contracted, and is expanded when the table 1 is extended.

That is, in the state in which the table 1 is retracted, the table shown in FIG.
As shown in (C), the pair of main top plates 2, 2 are butted against each other, and an auxiliary top plate 4 folded in two is held on the lower surface side thereof.

On the other hand, in the state where the table 1 is extended, FIG.
As shown in (C), the auxiliary top plate 4 is unfolded and sandwiched and held between the main top plates 2, 2. FIG. 5 is a cross-sectional view of the seat 1 shown in FIG. 3 in a contracted state, and the auxiliary top plate 4 is rotatably connected to a mounting piece 11 provided on the center rail 10.
Further, in FIGS. 3 to 5, 12 is a curtain plate of the main top plates 2 and 2, and 13 is a retractable curtain plate provided on the auxiliary top plate 4.

A pair of rails 15 and 15 which are parallel to each other are attached to both ends of the inner rail 10 and an outer rail 14 provided on the outside thereof, and as shown in FIG. The sliding member 16 engages with a groove provided on the inner surface of the rails 15, 15 to slide the main top plates 2, 2.

FIG. 6 shows a mounting structure of the rails 15 and 15, which are mounted parallel to each other and separated by the inner rail 10 and the outer rail 14. FIGS. 7 (A) and 7 (B) show the middle rail 10 and the outer rail 14, respectively, and a mounting piece 11 is vertically provided on the lower surface of the middle rail 10. Rails 15 and 15 are attached to both ends of the middle rail 10 and the outer rail 14 to form a groove 17 with which the slide member 16 engages together with the rails 10 and 14. 8th
The figure shows the mounting piece 11.

In FIG. 2, 6 is a sub-stile attached to the upper surface of the stile 5, 7 is a dowel hole, 8 is a spacer attached to the stile 5 by using the dowel hole 7 in the extended state of the table 1. Is a cover plate that closes the opening of the floor surface when the seat 1 is contracted.

[Problems to be solved by the device]

Wooden rails were used for the rails 15 and 15. However, since a large load is applied to the rails 15 and 15, there is a risk of breakage with a large-sized excavator.

Therefore, it is an object of the present invention to provide a digging table for an excavation table that is not easily broken.

[Means for Solving the Problems]

In the table for excavation table of the present invention, a pair of rails arranged in parallel to each other is a metal rail body having longitudinal grooves formed on the lower surface and the inner side surface, and a rail body having upper and lower edges. And a coating material made of a heat shielding plastic material having a substantially L-shaped cross section, which covers the outer side surface and the upper surface of the rail main body in a state of entering the groove.

[Action]

According to this invention, since the rail main body is made of metal, it is not easily broken even when a large load is applied. Moreover, the outer side surface and the upper surface of the rail body are covered with a covering material made of a heat shielding plastic material. Therefore, because the outer surface that is easy to touch when used is covered,
It is possible to prevent the user from touching the metal rail main body heated by the heat of the heater when using the excavator and being burned. Further, even when the top plate of the rail is exposed when the top plate is expanded and contracted during use and the top face of the rail is exposed, it is possible to prevent burns because the top face is covered.

〔Example〕

An embodiment of this invention will be described with reference to FIG. In other words, this table for excavation is the rail 15 in the conventional example.
Instead of the rail, a rail 20 is used as shown in FIG. The rail 20 includes a metal rail main body 18 made of an extruded material of aluminum having longitudinal grooves 21 and 22 on a lower surface 18b and an inner side surface 18c, and grooves 21 and 22 of the rail main body 18 at upper and lower edges. Rail body 1 with it entering
The outer surface 18d and the upper surface 18a of 8 are covered with a covering material 19 made of a heat shielding plastic material having a substantially L-shaped cross section. Similar to the conventional example, the rails 20 are attached to both ends of the inner rail 10 and the outer rail 14 by general fixing means (not shown) such as screws and adhesives, and the slide members 16 are engaged with the rails 10 and 14. A concave groove 17 is formed.

When a plastic material such as vinyl chloride resin is used as the covering material 19, this can be continuously extruded and molded on the outer surface of the rail body 18.

As described above, in this embodiment, since the rail main body 18 made of the extruded material of aluminum is used, the strength of the sliding mechanism of the main top plates 2 and 2 shown in FIG. 2 can be remarkably improved. Also, when energizing the digger heater,
The outer surface 18d of the rail body 18 that is easy for the user to touch is the covering material 1
Since the rail main body 18 is covered with 9, the user's body does not come into direct contact with the overheated rail body 18 and it is possible to prevent burns. Moreover, even if the auxiliary top plate 4 is removed and the upper surface of the rail 20 is exposed, the upper surface 18 of the rail main body 18
Since a is covered with the covering material 19, it is possible to prevent burns. Further, since the covering material 19 covers the upper and lower edges thereof in the grooves 21 and 22 of the rail body 18, the covering material 19 is securely attached to the rail body 18 and is not peeled off from the rail body 18.

The rail body 18 is not limited to the extruded material of aluminum, and other metal materials can be used as long as sufficient strength can be obtained.

[Effect of device]

According to this invention, since the rail main body is made of metal, the strength of the rail is improved and the rail is not easily broken even when a large load is applied. Moreover, the outer side surface and the upper surface of the rail body are covered with a covering material made of a heat shielding plastic material. Therefore, since the outer surface that is easy to touch during use is covered, it is possible to prevent the user from touching the metal rail body overheated by the heat of the heater and getting burned when using the digger. Further, even when the top plate of the rail is exposed when the top plate is expanded and contracted during use and the top face of the rail is exposed, it is possible to prevent burns because the top face is covered. Further, since the covering material covers the upper and lower edges thereof in the groove of the rail body, the covering material is securely attached to the rail body and is not peeled off from the rail body.
