Telescopically adjustable support

The innovation "concerns a telescopically adjustable Support with an inner square tube slidingly inserted into an outer square tube.

From FR-PS 2 492 047 a telescopically adjustable support formed from square tubes emerges. Furthermore, from US Pat. No. 4,352,479, a support is known which, with the aid of a threaded spindle and a nut arranged on this is adjustable.

The present innovation is based on the task of creating a telescopically adjustable support, which is particularly applicable in the field of construction, wood, joinery and carpentry and is characterized by a particularly simple and time-saving handling.

The support according to the innovation essentially solves this problem in that the inner square-shaped tube has an external thread extending at least over part of its length, which consists of only formed in the edge area of the square shaped tube Threaded sections consists, and carries a ring with an adjusting device, which by means of an internal thread engages in these threaded sections.

The support in accordance with the innovation enables quick pressing, pressing, To achieve posts, bracing and bracing, whereby

Comfortable operation is guaranteed due to the lack of pre-positioned holes, pre-positioned bolts, firing pins or clamping wedges. The new telescopic | adjustable support is suitable for wide application areas and f may, for example, as a screw clamp \ (frame), spindle channel, serve trestle, form ties, Bach console, etc. ceiling support. Another ; _The advantage here is that the square thread is easy to clean, especially when working with concrete, because, compared to a round thread, dirt particles can fall through at the flat spots with every slight rotation.

Advantageous embodiments of the innovation emerge from the subclaims and from the drawing, in which a support according to the innovation is shown, for example, in a longitudinal section »

The support 1 consists of two in cross section? square shaped tubes 2 and 7 together, which fit into one another ' which are plugged in. The inner |

Square shape tube 2 has an external thread (flat or f. Trapezoidal thread), which consists of only provided in the edge region thread sections 3. The inner shaped tube 2 carries a ring 4 with an internal thread 5 which engages in the threaded sections 3 of the inner shaped tube 2. On the ring 4, two rotary handles 6 are attached for actuation and by turning the ring, the inner shaped tube 2 can be adjusted relative to the outer shaped tube. The adjustable range of the support depends on the length of the thread on the inner shaped tube 2.

The outer shaped tube 7 is at one end 9 provided with a pressure ring or reinforcement ring 10 and has a support head 8 at the other end, the shape and size of which depends on the intended use.

can be suitable. A similar support head 11 is at the protruding from the outer tube 7 end of the inner molded tube 2 attached. A locking member 13 on the outer tube 7 acts with a recess 12 of the inner shaped tube 2 together and serves as a safety device to prevent accidental falling apart the shaped tubes 2 and 7 to prevent.

Because the thread is only on the edges of the inner molded tube and the dirt surface is very small, a Seibet cleaning of the thread is guaranteed. The load pressure of the column can be fully taken into account by selecting the material to be processed. For supports, when working can be used with a relatively low load pressure (e.g. when gluing door frame panels) thus molded tubes with a small cross-section and low wall thickness can be used, which is reflected in the manufacturing costs and has a beneficial effect on transport. Is the distributable area for certain work If the support is no longer sufficient (e.g. when inserting plastic stars), the new adjustable Support can also be adapted to these given circumstances in a few simple steps, as the extension of the Support only the fuse (locking member 13) is raised, then the outer tube is pulled off and an in the length needs to be replaced. The same procedure can be used if the support should be shortened *
