Table with extension parts that can be swiveled out around bolts

for the tabletop.

Patented in the German Empire on June 16, 1922 .

In the known tables with an extendable table top, in which the extension parts for the table top are arranged so that they can be swiveled out around bolts, the extension parts are located when the table is reduced on the middle table top so that the fixed table top is at the bottom and both of them Extension parts lie one above the other on this middle table top. The consequence of this Construction, is that the pivot pins of the extension parts must be arranged displaceably in their longitudinal direction in holes of a base plate, since the two extension parts must be lowered into the plane of the tabletop after they have been swiveled out. A displaceability of the pivot pin in their guided tours is only possible without difficulty if the

Claims (2)

Bolts already have enough leeway in their guides. Because of this alone and also because the guides work themselves out very quickly by moving the bolts up and down in their guides, the guide bolts alone do not give their swing-out parts a secure hold, so that these tables are provided with special support devices for the swing-out extension parts must, which makes the costs for the production of these tables so expensive that they can practically hardly be brought to execution at the current wage and material prices. The present invention should make it possible to give the pivotable parts a secure hold only through their pivot pins in that a longitudinal shift of the pivot pins no longer needs to take place, accordingly premature wear of the pivot pin bearings does not take place and the bearings can be designed so, that they form a long, reliable guide for the pivot pin. This is achieved in that, when the table is reduced in size, the two parts that can be swiveled out in the same; Level below the middle table top, which can be moved in the vertical direction. The leadership of the middle table top in! vertical direction can be done in the simplest way through a web lying between the strips of the table frame, and there: the two parts that can be swiveled out in! lie on the same plane, there is no longer any need to shift the fastening bolts after they have been pivoted out, which in turn can be stored in long guides attached to the table frame, so that these pivot bolts alone provide a firm hold against tilting the parts that can be pivoted out even after they have been pivoted out is given. In this embodiment, the table can then be produced in the cheapest way with the simplest tools. The drawing shows the invention in Fig. R to 3 with a shortened table top and in Fig. 4 and 5 with an extended table top, namely Fig. Ι is a plan view of the table, Fig. 2 is a section along the line from Fig. I , Fig. 3 is a front view of the table, Fig. 4 is a section along the line cd of Fig. 5 and Fig. 5 is a section along the line from Fig. Ι after the extension of the table top. The frame of the table consists of ilen strips 1, 2, 3, 4, with which the feet 5 of the table are connected in a known manner. In the middle of the frame, two parallel strips 6, 6 are arranged, which leave a slot 7 between them. The middle plate 8 of the table is provided with a web 9 which leads between the strips 6, 6, so that the plate 8 can be moved up and down, but is secured against rotation. On each of the opposing frame strips 3 and 4, a bearing 10 is attached, in which a bolt 11 is rotatable. The upper end of the bolt 11 is firmly connected to its extension plate 12, while the lower end of the bolt is permanently connected to a shelf 13. If the table is pushed together, as shown in FIGS. 1 to 3, the extension plates 12 lie under the middle plate 8, and the storage plates 13 are swiveled in between the feet 5 under the table. If the table is to be extended, the extension plates 12 are rotated in the direction of the arrows 14 (Fig. 1) out from under the middle plate 8 until they come into the position according to Fig. 4, then the middle plate 8 falls onto the frame 1, 2 , 3, 4 so that it forms a flat surface with the extension plates 12. Simultaneously with the pivoting out of the extension plates 12, the storage shelves 13 have also been pivoted out and come into the position according to FIGS. 4 and 5. If the table is to be shortened again, the middle plate 8 is raised and the extension plates 12 are rotated back into their initial position. 95 patent ax proverbs: 1.
