Designation: table frame

The utility model "refers to a table frame with 'Corner connectors which have connecting pins extending in all three directions of the room, aai »To which the frames and feet of the frame are connected are.

Table frames of this type, the corner connecting pieces Plastic are known per se. With them, the tubes forming the frames and feet are under tension over the ' associated connecting pin pushed and held by friction. Such table frames have the disadvantage relative low stability. They cannot be chrome-plated in the area of their corner connections, which is often required will.

Table frames are also the rigid, one-piece, U-shaped frame parts which represent the two end faces of the table frame and which are supported by two longitudinal frames are combined with each other to form the table frame. In the case of table frames of this type, production is relatively expensive. Often there is a Chromium plating is required to be great in this regard

Plants "required * the = shaped partial frames" earth to save space in the chrome bath only in the position in which it is closer are on the table frame. Experience has shown, however, that the overlying surfaces of the sub-frame in particular ! Degree of contamination by precipitation of dirt particles and the like. Are exposed.

The innovation is based on the task while avoiding the the disadvantages mentioned above to create a table frame that has favorable conditions for series production, the corners of which can be chrome-plated at a relatively low cost without contamination and one for everyone Needs sufficient stability.

This object is achieved by such a ^ dimensioning of the cross section of the tubes carrying Anschlußjsapfen the EckverbindungsstÜQke _y that there remains a free 'space between its underside and the inner surface of the associated tubes, wherein a bracing of the connecting pin to the associated pipes by means of the the lower wall area of the tubes supported and the connecting pin on the upper wall area of the tubes pressing screw bolts is reached.

The innovation is shown below on the basis of the drawing some embodiments explained.

The corner connectors are metal castings which have connecting pins 1 ¹ , 1 ", 1 ■" extending in all three directions of the room. The frames are formed by tubes 2-5. These tubes are attached to the associated connecting pins I ¹ , 1 " attached * Likewise, the feet 6-9 formed by tubes are attached to the downwardly protruding connecting pegs 1 '· »on which they sit in a form-fitting manner. All tubes 2-9 of the table frame have a rectangular or square cross-section. The connection pins 1 ·, 1 '· are dimensioned in cross section in relation to the cross section of the tubes 2-5 so that when the table frame is fully assembled, the connection pin 1% 1 "and the lower wall of the tubes 2-5 are between the undersides 10 free space 13 remains.

In the embodiment of Fig. 2, the connecting pin is 1 · clamped with the associated tube 5 in that a screw bolt 12, which is above a hole 14 in the lower Wall of the tube 5 is actuated, on the one hand with his' head is supported on this lower wall and on the other hand with the internal thread of a bore 15 in the connecting pin 1 'is engaged.

In the embodiment according to FIG. 3, the connecting pin is

I · with the associated tube 5 with the aid of a screw bolt

Claims (5)

• 3 claims for protection 1. Table frame with Eekverbindungsstücke, which have connecting pins extending in the three views of the seam, to which frames and feet of the G-frame forming tubes are connected, characterized by such a dimensioning of the cross-section of the connecting pins carrying the tubes (2-5) (1 ¹ , 1 ") of the Eclrverbindungs pieces (1) that a free space (13) remains between their underside and the inner surface of the associated pipes (2-5), and characterized by a bracing of the connecting pins (1 ', 1 ") with the associated pipes (2 - 5) with the help of screw bolts (12 in Fig. 2, 11 in Fig. 3). 2. Table frame according to claim 1, characterized in that the screw bolt (11) guided through a bore in the lower wall of the cross-sectionally rectangular or square tube (2.3 _f 4.5) engages with the internal thread of an abutment plate (15) stands and ^(s 11) in contact with the underside of the likewise rectangular or square cross-section terminal pin (1 ·) is located with its end face (Fig 3 _e), 3. Table frame according to claim 1, characterized in that the one with its head on the lower wall of the pipe (5) supported and actuatable via a hole in this wall screw bolt (12) with the internal thread of a The hole in the connecting pin (1 ») is in engagement (Fig. 2), 4. table frame according to one of the preceding claims, characterized in that the surfaces of the corner ■ connecting pieces (1) are chrome-plated at least in the areas not encompassed by the tubes (2-9). 5. Table frame according to one of the preceding claims, characterized in that the connecting pin (1 ^{I! T} ) which receives the tube (6,7,8,9) which forms the foot is profiled.
