Abstract

PROBLEM TO BE SOLVED: To prevent feet from tottering by providing a fixing member for clamp-fixing the feet to a mounting member in parallel to the folding direction of the feet. SOLUTION: By tightening a knob bolt screwed to a sleeve part 6 fixed to feet 3, the feet 3 are pushed and fixed to the surface parallel to the axial direction of the pin 4 of a foot mounting member 1a. The feet 3 are fitted surely to the member 1a. In this way, the rotation of the feet 3 inside a table 1 can be regulated to prevent the feet 3 from tottering. In order to increase the rigidity and safety of the feet 3 as required, two feet 3 are connected by a stay 7. When a main body is transferred or preserved not to use it, the stay 7 is removed, the knob bolts 5 are loosened and removed from the feet 3, and the feet 3 are turned inside the table 1 on the fulcrum of the pin 4 and folded.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg mounting mechanism for a circular saw machine for processing a work material with a circular saw protruding from an upper surface of a table.

[0002]

2. Description of the Related Art The prior art will be described with reference to FIGS. A table section folding structure of a conventional circular saw machine will be described. The legs 13 are inserted into the inner surfaces of the four corners of the table 11, and the knob bolts 15 are attached to the table 11 and the legs 13.
And the table 11 and the leg 13 are fastened by a sleeve 16 having a female screw. When folding the leg 13 into the table 11, the knob bolt 15
On the contrary, during the cutting operation, the knob bolt 15 is tightened to fix the leg 13.

[0003]

In the conventional folding type circular saw machine, since the knob bolt 15 is fixed at one position, when a load is applied from the side of the main body, the rigidity such as the leg 13 fluctuating or the folding main body falling down or the like may be insufficient. There was a problem of lack of safety.

An object of the present invention is to provide a circular sawing machine which solves the above-mentioned conventional disadvantages, prevents wobbling of legs, and has improved rigidity and safety.

[0005]

In order to achieve the above object, a circular saw having a circular saw protruding from an upper surface of a table and a leg for supporting the table is provided below the table. A leg mounting member for mounting the leg is provided, a rotation shaft of the leg is inserted into the leg mounting member and one end of the leg, the leg is foldably supported inside the table, and the leg is mounted on a side surface of the leg mounting member. A fixing member for tightening and fixing the leg is provided in parallel with the folding direction of the leg, and a screw fitting portion of the fixing member is provided on the leg.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 is a front view showing a leg mounting mechanism of a circular saw machine according to the present invention, FIG. 2 is a right side view of FIG. 1, FIG. 3 is a front view showing a state where a table portion of the circular saw machine is folded, FIG.
FIG. 3 is a sectional view taken along line AA of FIG. 2.

In the figure, a circular saw machine is mounted such that the upper half of the circular saw 2 protrudes from the upper surface of the table 1, and the circular saw 2 is covered with a contact prevention device 8. Table 1
Below, a leg 3 and a motor for driving a circular saw (not shown) are provided.

A leg mounting member 1a is fixed below the table 1, and a support member 1b is mounted parallel to one surface of the leg mounting member 1a. Leg attachment member 1a, support member 1b
A hole is formed perpendicularly to one surface of the leg mounting member 1a, and an end of the U-shaped leg 3 as viewed in FIG. 2 is formed in a U-shaped mounting portion formed by the leg mounting member 1a and the support member 1b. The portion is sandwiched, and the pin 4 serving as the rotation axis is inserted. As a result, as shown in FIG. 3, the leg 3 can be freely folded toward the inside of the table 1 with the pin 4 as a fulcrum.

Also, the leg 3 and the leg mounting member 1a
The through holes 1c and 3a for the knob bolt 5 are formed in parallel with the folding direction (in the direction perpendicular to the axial direction of the pin 4). The leg 3 is provided with a sleeve 6 having a female screw portion inwardly of the table 1. The knob bolt 5 is inserted from the through hole 1c, passes through the through hole 3a of the leg 3, and the knob bolt 5 and the sleeve 6 are screw-fitted, so that the leg 3 always hits the inner surface of the leg mounting member 1a. It is fixed in the state where it is.

In the above configuration, when the knob bolt 5 is tightened, the leg 3 is pressed and fixed to a plane parallel to the axial direction of the pin 4 of the leg mounting member 1a. The leg 3 surely hits the leg mounting member 1a. Thus, the rotation of the leg 3 toward the inside of the table 1 can be restricted, and the leg 3 does not shake. Also, in order to increase rigidity and safety if necessary, the two legs 3 are connected by a stay 7.

When the main body is moved or transported, or when the main body is to be stored for not being used, as shown in FIG. 3, the stay 7 is removed, the knob bolt 5 is loosened and the main body is removed from the leg 3,
The leg 3 is folded by rotating the leg 3 in the direction of the inside of the table 1 with the pin 4 as a fulcrum.

[0012]

According to the present invention, the legs are tightened and fixed in parallel with the direction in which the legs are folded, so that the legs can be securely fixed to the table during the cutting operation, so that the legs are stable and stable. Available in condition.
