HU192793B - Supporting rack of variable height - Google Patents

Abstract

The variable height support buck cross-sectional cross-section rod (3) or Pipe is made by column design. On the rod (3) (preferably it may be tube), multiple transverse insertions (6), which inserts the rod as a ring a shaping disc (4) surrounding it. The Shaped disc (4) prevents the rod tube slipping apart but adjusting the height turning the dial, its shape bore allows the rod to be longitudinal displacement. The dial in the desired location to insert the polygonal rod (3) ” the recording is created again. The figure Nails for random rotation of the disc (5) prevent it

Description

FIELD OF THE INVENTION The invention relates to a device of variable height for supporting objects, particularly for a fixed hitch.

It is known that in the fields of industry, construction, vehicle manufacturing and repair 5 it is often necessary to lay down objects at fixed heights. The adjustability is usually provided by a threaded spindle or by a cross-bore bolt-type solution, which are slow-edged, cost-effective manufacture or assembly. using other materials instead of the prescribed studs may present an accident hazard. No. 3,606,254. US-A describes a 3-legged rack with 15 slippers mounted on a rack on the platform of the elevator. The disadvantage of this solution is the inaccuracy of the load. No. 3,788,604. In the US description, there is a hoist which engages two of the telescopically inserted tubes in each of the inner teeth of the punctures. This solution can become dangerous if foreign materials are blocked by breakthroughs. The preferred embodiment of the height-adjustable support bracket shall ensure a uniform and indivisible structural construction, excluding the replacement of parts with foreign materials.

According to the present invention, a polygonal cross-sectional matching rod and tube is used as an adjusting member. The tube may also be formed in a preferred configuration on the inside rod, making recess (s) perpendicular to its component direction. The depth of insertion is chosen so that there is no continuous groove on the side surfaces. The rod and tube are prevented from sliding into each other by a molded disc, which engages in a recess formed in the rod at the upper end of the outer tube. The adjustment is made by moving the shaped disc to a different groove in the bar. This is possible by rotating the disc in the insertion so that the shaped bore no longer obstructs the axial displacement of the bar.

The device of the invention ⁷ is easy to operate. Excludes the use of foreign materials, usually of lower strength, as fasteners. The adjustment can be done in a short time, the fixing is secure.

This invention relates to:

Variable-height support bracket with matching polygonal cross-sectional rod or tube column design, characterized in that the polygonal bar has transverse grooves and has a disc-shaped bore that fits therein.

The invention is illustrated by the accompanying drawings.

Figure 1 is a side elevational view of the variable height support bracket of the present invention.

Figure 2 is a sectional view taken along line A-A of Figure 1.

The three support legs 1 are welded to the outer tube 2 of triangular cross-section. The rod 3 has, as in the example, an evenly triangular tube, but there are 6 insertions for height adjustment. Three stops 5 are mounted on the underside of the shaped disk 4 to secure the disk against rotation. Therefore, when adjusting, the rod 3 must be slightly raised so that the insert-shaped disc 4 can be rotated. To ensure dismantling, the rod 3 has a detachable stop 7 to facilitate transport.

Claims (3)
