Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a work table table device in which a wagon stand is stored in a cabinet so that it can be put in and taken out. Stopper lever on the rear end that can be raised and rotated freely
7 is installed, and the operation lever 8 for raising and lowering the stopper lever 7 from a substantially upright state protruding upward from the top end of the wagon stand 2 to a substantially horizontal state located below the top end of the wagon stand 2 is moved to the top of the wagon stand 2. A crosspiece 5 provided on the side and against which the stopper lever 7 in an approximately upright state hits when the wagon stand 2 is pulled out from the cabinet 1 is attached to the upper end of the opening 4 of the cabinet 1. This relates to a workbench table device characterized in that a catch device 6 having an elastic curved piece 22 that is engaged by the stopper lever 7 when the stopper lever 7 is rotated is fixed to the back surface of the crosspiece 5. be.

An object of the present invention is to perform operations for preventing the wagon stand from being separated from the cabinet, fixing the wagon stand to the cabinet, and separating the wagon stand from the cabinet by simply operating a stopper lever using an operating lever. It is an object of the present invention to provide a workbench table device that is easy to perform and can be used in various ways.

The present invention will be explained in detail below with reference to Examples.

The cabinet 1 is formed of a box-like body with an opening 4 for entrance and exit at the front and an opening at the bottom, and as shown in FIG. There is an opening 4 at the front end of the top plate 11.
A crosspiece 5 is attached so as to hang down.

The rail groove 10 runs horizontally near the opening 4 and diagonally toward the back.

By recessing the rail groove 10 into the inner surface of the side plate 9 in this manner, the inner dimension between the side plates 9 can be utilized to the maximum extent.

A pair of catch tools 6 are fixed on the back side of the crosspiece 5.

The wagon stand 2 has casters 13 attached to the legs 12, a wagon table plate 14 attached to the upper surface of the legs 12, a door plate 15 attached to the front end of the wagon table plate 14 on the front side of the legs 12, and a wagon table plate 15 attached to the front end of the wagon table plate 14 on the front side of the legs 12. The table plate 3 is attached to the wagon table plate 14 at a hinge 16 so as to be movable vertically from a horizontal position to a substantially hanging position.

This hinge 16 is a spring-loaded hinge to which a spring 17 is attached, and the spring force acts in a direction to rotate the table plate 3 upward.

However, there is no force to rotate the table plate 3 against its own weight.

The lever 18 is formed by bending the stopper lever 7 at one end and the operating lever 8 at the other end, and is attached to the lower surface of the rear end of the table plate 3 with a pair of bearing plates 19, and the stopper lever 7 is bent at the other end. The levers 18 are mounted at positions where the lever 7 projects from the rear end of the table board 3 and the operating lever 8 projects from the side end of the table board 3, respectively.

Further, rollers 20, 2 are provided at both ends of the rear end of the table plate 3.
0 is attached, and the roller 20 is inserted into the rail groove 10.

Therefore, when storing the wagon stand 2 in the cabinet 1, when the wagon stand 2 is moved inward from the opening 4 into the cabinet 1 using the casters 13, the rollers 20 fit into the rail grooves 10 of the side plate 9 of the cabinet 1. As it moves along the table board 3, the table board 3 rotates downward due to its own weight and becomes in a substantially hanging state, and the table board 3 and the wagon stand 2 are stored in the cabinet 1 as shown in FIG. 2a. Ru.

At this time, the door plate 15 of the wagon stand 2 serves as a door that closes the opening 4 of the cabinet 1 as shown in FIG. 2C.

Furthermore, since the table plate 3 rotates downward under its own weight, the rollers 20 follow the rail grooves 10 during this rotation, so that the wagon stand 2 can be smoothly accommodated in the cabinet 1 with a small force.

Next, when the wagon stand 2 is pulled out from the cabinet 1 and work is performed on the wagon stand 2, the handle 21 on the upper part of the wagon stand 2 is grasped and the casters 13 are moved to pull it out from the opening 4.

Since the part 20 from which the wagon stand 2 is pulled out moves along the inclined rail groove 10, the table plate 3 rotates upward as shown in FIG. 3A.

At this time, since the table plate 3 is biased in the upward rotation direction by the spring 17, the table plate 3 rotates smoothly due to the biasing force of the spring 17 without the need to pull the wagon stand 2 with strong force. Become.

When the rollers 20 reach the horizontal part of the front end of the rail groove 10, the table plate 3 becomes the wagon table plate 1 as shown in FIG.
It will be in a horizontal state flush with 4.

At this time, the stopper lever 7 is in a vertical position, and the stopper lever 7 abuts against the back surface of the crosspiece 5 of the cabinet 1 as shown in FIG. 4a, thereby preventing the table board 3 from coming out of the cabinet 1. The wagon stand 2 and the cabinet 1 can be used as an integral unit without being separated from the cabinet 1.

Also, as shown in Fig. 3b, by pulling the operation lever 8 and tilting the stopper lever 7 slightly from its upright position, the stopper lever 7 can be moved to the catch tool 6 as shown in Fig. 4b.
When the table board 3 is engaged with the elastic bending piece 22 of the cabinet 1, the table board 3 is coupled to the crosspiece 5 of the cabinet 1, and the table board 3 is prevented from retracting into the cabinet 1.
can be fixed.

In this way, work can be carried out over a wide area both on the wagon table plate 14 of the wagon stand 2 and on the table plate 3.

Furthermore, when you want to pull out the table board 3 from the cabinet 1 and separate the wagon stand 2 from the cabinet 1,
First, pull out the wagon base 2 until the stopper lever 7 hits the crosspiece 5, then move the wagon base 2 back a little, and in this state rotate the operating lever 8 until it hits the bottom surface of the table board 3 as shown in Figure 4C. By doing so, the stopper lever 1 is tilted down, and after the stopper lever 7 is brought into a substantially horizontal state where it does not come into contact with the crosspiece 5, the wagon stand 2 is pulled out as shown in Fig. 3C, and as shown in Fig. 4D. Like table board 3
is pulled out from the opening 4 of the cabinet 1, and the wagon stand 2 can be separated from the cabinet 1.

In the figure, 23 is a stop protrusion that prevents the stopper lever 7 from rotating outward and the operation lever 8 from being pulled into the depths of the lower surface of the table board 3, 24 is an adjuster, and 29 is a counter.

As described above, in the present invention, by simply operating the operating lever and rotating the stopper lever, it is possible to prevent the wagon stand from slipping out of the cabinet, fix the wagon stand to the cabinet, and prevent the wagon stand from slipping out of the cabinet. The device can be separated from the cabinet, these three functions can be achieved by simply operating the operating lever, and it can be used in various ways.

In addition, by operating the operation lever in this manner and engaging the stopper lever with the elastic curved piece of the catch tool, it is possible to prevent the stopper lever from hitting the cabinet crosspiece and the wagon stand slipping out of the cabinet. This prevents the wagon stand from entering the cabinet again when the stopper lever engages with the elastic curved piece of the catch, so the wagon stand can be stably engaged with the cabinet without moving. This allows the wagon stand to be used in the upright position.

In addition, the connection between the wagon stand and the cabinet using the operating lever can be done by hand by rotating the operating lever and engaging the stopper lever with the elastic curved piece of the catch tool attached to the crosspiece. is simple.
