It is coupled to the shaft hole (a) formed biased to the lower body of the leg (L1).

In addition, each of the rotation members 200 is provided with a stopper 200c for the stability of the state supporting the worktable (L) of the wheel 100.

Further, the rotation member 200 is in a non-contact state of the ground of the wheel 100,

More precisely, when the wheel does not support the load of the work table L and the non-slip member 20 at the bottom of the leg is firmly brought into contact with the ground,

The locker 400 to be described later has a round portion 200b (see FIG. 3A) for guiding easily away from the engaging groove 200c ′ (see FIG. 3A) of the rotation member 200.

Next, the moving part L3 is in a state in which the wheel 100 is in contact with the ground.

(As mentioned earlier, more precisely, the wheels support the load on the workbench (L).)

It is preferable to further include a locker for fixing the,

In particular, in the drawings, the locker is provided under the two legs (L1) main body 10 so that the operator can operate by foot in an upright state.

It consists of a rocker in the form of a rod,

More specifically, the two pivot members 200 (ie, two wheels 100 provided on one pair of legs of the workbench) may be provided at the lower hole A at both lower sides of the leg body 10 so as to simultaneously lock and lift them.

It is composed of one bar locker (400).

The function of the locker 400 enables one-touch (or snap) type locking-unlocking, so that mutual switching of the state of using the wheel or moving the workbench when the workbench is moved or non-moved (that is, at work) is not possible. It can be done easily.

Referring to FIGS. 3A and 3B and FIGS. 6A and 6B, the function and operation state of the moving unit will be described in more detail.

The rod-shaped rocker 400 is to remain in the state coupled to the defect groove (200c ') of the rotating member 200 by the coil spring 500,

One end of the coil spring 500 is coupled to the locker 400, and the other end is coupled to the rotation shaft pin 200a serving as a fixing member.

As can be seen in Figures 3a and 3b, the separation prevention of the connection member 300 fitted in the lower body hole (A) of the leg (L1) body 10 is made by a washer (c) coupled by welding or the like. (Various variations as required),

The departure prevention of the other end of the spring 500 coupled to the pivot shaft 200a is made by a nut c '.

6a when the wheel 100 supports the load of the work table (L)

When the worker lifts one pair of legs of the workbench L, the rotating member 200)

(More precisely [two wheels 100-two rotating members 200-coupling member 300 combined])

The wheel 100 by turning around the shaft pin (200a) by its own weight

In the state of FIG. 6B in which the work table L load is unsupported

The working table L load supporting state of FIG.

Accordingly, the rocker 400, which was under downward tension by the spring 500, descends along the lower long hole A of the leg main body 10.

(At this time, the round part 200b of the rotating member 200 is important to guide the two wheels 100-the two rotating members 200-the connecting member 300 to be smoothly lowered without being caught by the locker 400. Will play a role)

While coinciding with the engaging groove (200c ') of the rotating member 200 is switched to the locked state,

At this time, the stopper 200c of the pivot member 200 is in contact with the outside of each leg body 10 to ensure the correct coupling and tightness of the locker 400 and the coupling groove 200c '.

Accordingly, the wheel 100 is to support the load of the work table 100, the leg (L1) body 10, the bottom anti-slip member 20 is spaced apart from the ground by a certain height (h).

Next, when the worktable is completed, the worktable is arranged at the work position and the wheels are folded to ensure the firmness of the upright state.

The worker may lift up the locker 400 by using the instep of the foot in an upright state without bowing or lowering,

Accordingly, the spring 500 is extended and the locker 400 is positioned above the lower body hole A of the leg body 10.

The wheel 100 has a load of the working table (L)

Rotating member 200 has no resistance, so turning the shaft pin (200a) to the shaft as shown in Figure 6b

(At this time, the round part 200b of the rotating member 200 plays an important role of guiding the two rotating members 200 to smoothly turn without being caught by the locker 400.)

Accordingly, the lower slip member 20 of the lower body of the leg L1 contacts the ground.

The wheel 100 is heard from the ground and a certain height (h).

In order to more securely lift the wheel lifted state is preferably formed one more coupling groove in the corresponding position of the rotating member 200,

Although the locker 400 presses the round part 200b of the rotation member 200 by the spring 500 to keep the wheel 100 lifted at a predetermined height h,

Vibration is applied to the workbench L so that the wheel 100 pivots by its own weight (more specifically, the self-weight of [two wheels 100-two pivoting members 200-coupling member 300] combination) in contact with the ground. Even if

Since the actual load of the workbench L is supported by the legs L1, the situation in which the workbench moves does not occur.

The second coupling groove of the rotation member 200 to more firmly fix the lifted state of the wheel is not necessary.

Next, the present invention is preferably provided with a height adjusting means so as to freely adjust the height of the footrest according to the working environment.

The height adjusting means for the work table (L) can be both the method of adjusting the length of the leg (L1) body 10 itself, and the method of adjusting the coupling position of the footrest (L2) coupled to the leg (L1). Do.

In order to adjust the height of the more durable footrest portion 1 and 2 and 3 and 5 is shown the height adjustment means employing the latter method.

Looking more specifically at this,
