ES1156485U - Folding light table (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Folding light table of the type comprising an upper board (1) which is mounted on a metal support (2) to which the folding legs (3) are articulated, characterized in that the upper board is constituted by a frame or internal perimeter frame of wood (4) of approximately 26 mm in thickness, provided in defined areas with wooden crosspieces (5), which form in the frame some cavities or recesses (6), in order to accommodate expanded polystyrene sheets (7) of medium density and of the same thickness as the frame, which is covered on both sides by means of sheets of a compact phenolic (8) of 2 mm. Of thickness, which are joined to the wooden frame by adherent means in a pressing operation, in order to configure a single block, whose edge is covered by a perimeter thermoplastic and profiled edge (9) of 2mm thickness, which is attached to the block by gluing.

Once the block is formed, it is machined with the desired rectangular shape and its edge is covered by a 2mm thick thermoplastic and profiled perimeter edge (9), which is attached to the block by gluing. The plastic used is called ABS, highly resistant to shocks.

5 In the third and fourth figure, it is observed that the support of the board is formed by an aluminum frame, whose profiled aluminum beams (10) are provided with through holes (11) for fixing to the board, while on its face internal side has mechanized fittings (12) for the insertion and

10 union of aluminum reinforcements or crossbars (13).

Also in the fifth figure it can be seen that the crossbars (13) have threads in their heads, some screws that will fit in the machined fittings (12) facing the stringers (10), the immobilized

15 crossbar screws in their housings, which will be closed superiorly by the board. These screws are arranged anchored in both testas of each crossbar, but in the drawing the screws in the internal testa have been omitted for greater clarity of the fittings.

20 All this is arranged so that the aluminum frame will be mounted on the board in approximate coincidence with the internal wooden frame to fix the aluminum frame beams to the beams of the wood frame of the board by means of screws that cross the beams of aluminum until threading in the wooden frame.

25 In the sixth figure it can be seen that the crossbars (13) of the aluminum frame allow the support and fixing of mechanical means (14) for opening and closing the folding legs, which are provided with a safety lever (15) which releases the rotation of a connecting rod (16) articulated to each folding leg,

30 Likewise, in the sixth and seventh figures it can be seen that each leg is configured with three different steel profiles welded on a "U" side, which allow compensating or balancing the weights of the folding light table.

35 Each leg of the U-shaped configuration table has a side profile

(17) cylindrical, which is supported transversely on vertical boxes

10

ends (18) of the stringers, with the possibility of turning on their supports, as a pivot axis of the leg, while the other side profile (19) has a flat surface provided with end taps (20) supporting the leg on the ground, as well as leaning on the stringers when folding the

5 leg

These lateral profiles of the side "U" leg are joined by the intermediate profile (21) in the form of a bar that determines the height of the leg and on which the connecting rod (16) of opening and closing said leg is articulated.

10 Similarly, in the sixth and seventh figures it can be seen that the extreme vertical boxes (18) of the stringers have the shape of a hollow rectangular prismatic body, provided with anchoring means (22) for fixing to the stringers, as well as a hole (23) that receives a bushing (24) that acts as

15 housing for free rotation of the cylindrical side profile (17) or rotary axis of the leg.

In addition, each box is closed in its lower area by a reinforced block (25) with brackets, which is provided on its base with non-slip means (26), which

20 is located below the axes of rotation of the legs in a position to allow the stacking of the inverted tables to occupy less space in their storage and / or transport.

In this way, the support of the board (1) of an inverted upper table is allowed,

25 on the four reinforced blocks (25) of the boxes (18) of an inverted lower table, which with the non-slip means (26) provided in the support base of the blocks prevents sliding between the stacked tables.

In the eighth and ninth figures it can be seen that the folding light table is

30 capable of incorporating a front panel (27) as a skirt for closing the table hollow, provided on the upper edge of L-shaped profiles (28) as handles, while on the inside they have lateral profiles in the form of omega (29) in a position to be hooked to angular eyelashes (30) formed in at least the reinforced studs (25) of the boxes

35 front of the table.

Also in the eighth and ninth figures it can be seen that the table is

capable of having a power strip mounted on the top panel (1)

electrical connections (31), equipped with at least two angular plates on its front

(32) open towards the inside of the table, which are provided in its horizontal section

5

of tightening screws (33), ready to be coupled and fixed to the edge of the

table .
