Description

Description

The invention relates to a detachable connection for rod-shaped components, in particular those with a round cross-section for creating flat or three-dimensional frameworks. Such a connection is known from DT PS 1609419. A merging of the rods in a spherical or polyhedral node is also described in various patent documents. In these solutions, only spatially defined angular positions of the rods among each other are possible for the connection of the rods to the node. Furthermore, designs that enable a ring-shaped connection of the rods are known from patent documents DT PS 420823, DT PS 1609419, DT PS 2232378, CH PS 128174, Fr PS 923264. This design connects all the rods directly to a circular node connection in one plane. It is possible - by using angled rods - to form spatial frameworks, as described in the patent specification DT PS 1609419. However, this means that the angular positions of the individual rods to one another can only be freely selected within this one plane.

The aim of the invention is to propose a connection of the type mentioned at the beginning which makes it possible to detachably connect as large a number of bars as possible in spatially free, i.e. vertically or horizontally selectable angular positions to one another, in order to thereby achieve a high degree of variability. According to the invention, the above object is achieved with a connection of the type mentioned at the beginning in that one or more single- or multi-part, cylindrical or prism-shaped components, the axes of rotation of which coincide with the axis of the bar, are soldered, welded, mounted or similarly connected at any point, but preferably at the end of a bar, to which single- or multi-part, mechanically detachable connecting elements which define the angular position of the bars to one another and are either rigid or adjustable in defined or continuously angular positions are attached in a circular or prism-like manner, in defined or continuously adjustable positions. bii &Ggr;·: &eegr; W i nk>. 1:, &igr;. e 1 lungs perpendicular to the bar axis, to which 1 is constructed on the other hand in the same way'.; and ..in .lmlere St -ib ■ ■ b<·:;f<-■;!.&igr;<; t. <■ r components, u &lgr; sch I &igr; »ii b ..irsi &eegr;·&Iacgr; .

In the embodiment according to Fig. 1 - 3, a cylindrical component (2) provided with holes and countersinks is attached to a pipe (1) with the aid of the screw connection consisting of parts (3) and (4). The screw (9) connects the connecting parts (7) and (8) to the cylindrical component (2) in a force-fitting manner via the friction surfaces (5) and (6). In this example, a spring ring (14) is used to secure the screw (9). A guide (12) is used to position the connecting parts (7) and (3) precisely relative to one another. A joint part (10) located on the connecting part (8) has a radial toothing (11) directed towards the joint center, which enables another identical connecting element to be connected in a force-fitting manner with the aid of a screw connection through the hole (13) with countersink. In this example, the angle between two bars can be locked in 15 degree increments.

In Fig. 16 - 17, the cylindrical components with threaded holes (18) and cylindrical countersinks are connected to the rod (20) by friction using screws (19). Fig. 20 - 21, 28 - 29 show possible connections of a cylindrical component with a wooden rod, whereby a tab is fastened to the wooden rod with bolts in the milled groove of a wooden rod. In Fig. 20 - 21, a tab is connected to a cylindrical component homogeneously or by welding. In Fig. 28 - 29, a tab is connected to a wooden rod in the same way as in Fig. 20 - 21. The tab itself, however, has a homogeneously connected or welded head plate (21) on its front side. This is connected to a cylindrical component by the screw (22) and the nut (23) - positioned within the recess (24).

In Fig. 22 - 23 and 30 - 31, a bolt (26) is attached to a tubular rod through a hole (25) using lock washers, split pins or similar (27). This bolt (25) is surrounded by a cuboid (28) on the front side (31) of which a screw bolt (29) is connected, by means of which a cylindrical component is attached to a tubular rod using a nut (30). In Fig. 22 - 23, a cylindrical component encloses the end of a tubular rod, while in Fig. 30 - 31, a cylindrical component partially protrudes into the end of a tubular rod.

Fig. 49 - 50 show a variant for the design of the connection of the joint (92) to the one- or multi-part connecting elements (86) - (92). The fastening of the connecting elements (86 - (91) to cylindrical components (85) is carried out as shown in Fig. 1 - 3, but in order to increase the cross-section of the connection of the joint (92) to parts of the respective connecting elements (86) and (89), the side surfaces (93) and (94) of the respective connecting elements are fitted to the outer radius (95).
