Abstract

A demountable support for a table, esp. for a butcher's bench, comprises a flat frame for supporting the bench top and equipped beneath with four block-shaped fixing elements, onto which four legs can be pushed; a bottom frame comprising the feet can be pushed onto the bottom ends of the legs, and a bolt is pushed up through each leg to screw into the block and hold the assembly firmly together. Preferred materials are: for the blocks, aluminium pressure castings; for the top structure and legs, square tubes of aluminium or stainless steel, and for the bench support, stainless steel. This arrangement is easy to dismantle, stiff and strong and has comparatively small transport volume.

Substructure for tables

In factories producing sausage products and in butcher shops, meat on butcher's tables varies Finishes processed. The butcher's tables are designed as step or flat tables and are preferred equipped with a plastic worktop. In addition to the plastic plate, step tables also have a shelf made of stainless steel. In addition to the tables with a fixed base, there are also dismantling tables on the market for which you can unscrew the upper part with the table top from the substructure with the four table legs. The table substructure is in many embodiments made of aluminum square tubes and with an intermediate grate or an intermediate floor fitted.

The dismantling table stands out from the tables with a table top that is firmly attached to the substructure a significantly smaller space requirement during transport and the resulting lower transport costs.

A disadvantage of almost all dismantling tables is the lack of stability. Stable cutting tables are structurally very complex and therefore expensive.

The invention is based on the object of developing a collapsible substructure for tables, the construction of which the Advantages of a small transport volume and great stability combined.

According to the invention, this object is achieved by a dismountable substructure, which is characterized by a support

frame for the table top, on the underside of which there are four block-shaped fastening segments are arranged, four table legs that can be plugged onto the fastening segments, a substructure with four standing feet each with a connector element for fastening the feet to the table legs and Connecting bolts that can be pushed through from below through the standing feet and the table legs with one in the fastening segments can be screwed into the underside of the support frame Thread end.

In an advantageous embodiment of the invention, the Fastening segments designed as a square for attaching the square tubes used as table legs, and the Fastening segments have a foot with a square groove for inserting a table leg and a threaded hole a funnel-shaped centering opening for a connecting bolt.

The invention experiences an expedient further development through a piece of round pipe inserted into the upper end of the standing feet of the substructure for insertion into a table leg as well as an insert sleeve fastened in the lower end of the upright feet with a downwardly open threaded hole for receiving a height-adjustable screw foot and a closure cap located within the standing foot, which has a through-hole for the connecting bolt and acts as an abutment serves for the bolt head.

Finally, the invention provides that the fastening segments for the table legs are aluminum die-cast parts.

The table substructure that can be dismantled according to the invention is characterized by high stability and good transportability the end. Due to the simple construction, even the layman can quickly and easily use the table top with the base assemble.

The invention is explained in detail below with reference to an embodiment shown in the drawing. Show it

Fig. 1 is a perspective view of a step table a plastic worktop,

2 shows a side view of the table without the side frame, ., eat a half with the individual parts blown up and the other half of which is shown in the assembled state,

3 shows the longitudinal section through a standing foot of the substructure and

4 shows a cross section in the area of the plug connection between the table leg and the standing foot of the Underframe.

The mainly intended for butchers step table 1 with a rectangular shape for processing meat according to the FIGS. 1 and 2 consist of an upper part 2 and a substructure 3.

The upper part 2 has a support frame 4 made of longitudinal members 5,6,7 and cross members 8, 9, which are made of aluminum or Stainless steel square tubes are made. On the support frame 4 is the table top 10 made of stainless steel, designed as a step plate, with a storage plate 10a and a stepped step 10b, on which a countertop 11 made of plastic rests loosely attached. The table top 10 is provided with a side frame 12 framed by low wall parts, one of the worktop 11 fixing subframe 12a and one opposite has this raised part frame 12b, which surrounds the tray 10a and prevents pieces of meat from falling to the ground fall.

The essential components of the dismountable substructure 3 are a frame with a rectangular intermediate grate 13, at the corners 4 made of aluminum square tube Standing feet 14 are arranged, and four also as aluminum

Square tube made table legs 15, which with their lower Each end can be slipped onto a tubular piece 16 inserted into the upper end of the upright feet 14. For the standing feet 14 and the table legs 15, square tubes made of stainless steel can also be used.

In the lower end of the upright feet 14 of the substructure 3, an insert sleeve 17 made of aluminum is pressed, the one downwardly open threaded hole 18 for receiving a height-adjustable screw foot 19 and one within of the standing foot 14 has a closure cap 20 with a through hole 21.

On the underside of the support frame 4 for the table top 10 are block-shaped, square-shaped fastening segments 22 made of die-cast aluminum at the four corners arranged, on which the table legs 15 of the substructure 3 are attached. The fastening segments 22 have a Foot 23 with a square groove 24 for inserting the upper end of the table legs 15 and a threaded hole 25 with a funnel-shaped centering opening 26.

When assembling the upper part 2 with the substructure 3 of the The step table 1 is inserted from below through each standing foot 14 through the bore 21 in the closure cap 20 of the insert sleeve 17 and the table leg 15 placed on the standing foot 14 is fitted with a connecting bolt 27, the threaded end 28 of which passes through the funnel-shaped centering opening 26 slides into the threaded hole of the fastening segment 22. With one from below in When the socket wrench is inserted into the vertical foot 14, the threaded end 28 of the threaded bolt 27 is inserted into the fastening segment 22 screwed in so deep that the support frame 4, table leg 15 and standing foot 14 are firmly braced against one another, the bolt head 29 is supported on the closure cap 20 of the insert sleeve 17, which serves as an abutment. Then from A screw foot 19 is screwed into the insert sleeve 17 of the four standing feet 14 of the table substructure 3 at the bottom.

By means of the connecting bolts 27 in the simplest way Assembled step table 1 is so stable that it can withstand the heavy loads that occur in the rough butcher's work with the required operational reliability.
