FIG. 2 is a bottom perspective view of an enamel-coated desk according to the first embodiment of the present invention,
Fig. 3 is a longitudinal section taken along the longitudinal direction of Fig. 2,
Fig. 4 is a bottom perspective view of an enamel coated desk board having a frame fixing part on its bottom according to a second embodiment of the present invention
Fig. 5 is a longitudinal section taken along the longitudinal direction of Fig. 4,

As shown in FIGS. 2 and 3, the enamel coated desk plate A having the frame fixing protrusions on the bottom according to the first embodiment of the present invention includes an enamel coated desk top plate 10, And an insertion hole 24 in which a support leg 2 is inserted and fixed is formed in a bottom surface of a lower portion of the frame fixing projecting portion 21, And a desk main body 20 formed to protrude therefrom.

In the present embodiment, the upper surface 10 of the desk is described as being enamel-coated. However, the upper surface of the desk 10 is not limited to an enamel coating, The main body 20 corresponds to the right scope of the present invention.

In this embodiment, since the desk main body 20 is injection-molded by synthetic resin, the frame fixing protrusion 22 is a stretchable structure in which the interval between the insertion grooves 23 is temporarily widened and contracted again. Since the width W1 of the insertion groove 23 is smaller than the diameter D1 of the support leg 2 to be inserted, the support leg 2 is inserted into the insertion hole 24 As shown in Fig.

3, when the pipe-shaped support legs 2 are inserted into the frame fixing projections 22, the insertion grooves 23 of the frame fixing projections 22 Is temporarily opened while the support leg 2 is passed and the support leg 2 is opened at the maximum at the portion where the diameter D1 of the support leg 2 passes (indicated by a chain double-dashed line) The inserted insertion groove 23 is retracted while being inserted into the insertion hole 24 so that the support leg 2 is inserted and fixed in the insertion hole 24.

The enamel coated desk board A having the frame fixing protrusions on the bottom according to the first embodiment of the present invention can easily and quickly fasten the support legs 2 to the desk top panel A, Since the frame fixing projections 22 are projected on the bottom surface of the main body 20, the carrying amount of the enamel coated desk A is reduced by the height of the projected frame fixing projections 22, There is a possibility that the protruding portion 22 is broken. Therefore, an enamel coated desk board A having a frame fixing protrusion on the bottom surface according to the second embodiment of the present invention has been proposed.

As shown in FIGS. 3 and 4, the enamel coated desk board A having the frame fixing protrusions on the bottom according to the second embodiment of the present invention includes an enamel coated desk top surface 10, A desk main body 20 in which a placement groove 21 in which a face 10 is disposed at an upper portion and a fixing groove 25 is formed at a bottom portion of a lower portion on which a support leg 2 is disposed, And the other end of which is formed with an insertion groove 28a which is opened downwardly and an insertion groove 28a which is opened downward and a support leg 2 which is inserted and fixed in the insertion groove 28a. And a support leg fixing piece 26 having a frame fixing protrusion 28 formed with a frame 28b.

Since the desk main body 20 and the support leg fixing pieces 26 are manufactured in a state in which the desk main body 20 and the support leg fixing pieces 26 are separated from each other, And the support leg fixing piece 26 is detachably held in the fixing groove 25 of the desk body 20 at a site such as a classroom And the attachment of the support leg 2 to the desk main body 20 is the same as that already described in the first embodiment, so that a description thereof will be omitted.
