DE2826600A1 - Seeding table for use in greenhouse - has base supported on rollers with stops limiting their rotation - Google Patents

Abstract

A trough-shaped table bed rests on a base, and between the base and the table bed underside are roller elements. The roller elements consists of round bars (5) aligned parallel to the table bed longitudinal axis. As a fixing device, one of the bars has a stop which limits it rotation and can be brought into the region at its roller path. The stop is a sheath section (6) which grips around the bar (5) and has radial projections (7, 8). The bar and sheath section can be engaged and disengaged from each other.

Roller lock for a culture table equipped with Holl elements for horticultural companies

The invention relates to a culture table for horticultural companies, with a v / annen-like table bed resting on a substructure, with between the substructure and the underside of the table bed Rolling elements are arranged according to patent ... (patent application P 26 42 108.9-23).

With culture tables of the aforementioned type, the usable area of the table beds within a greenhouse can be reduced enlarge. If you work on a table bed from both sides, an undesired shift can occur. what risk of accident for those working at the table beds Persons means.

The invention is based on the object of avoiding the unintentional bulging of the table beds.

This object is achieved according to the invention

been., that at least one of the rolling elements has a locking device Has.

This allows the table bed to move in its own right reached end position locked; .ground. Rolling back is no longer possible, even if there are stronger thrust forces should occur.

In a preferred embodiment of the culture are seen as rolling elements at least two parallel to the table bed longitudinal axis aligned round profiles gate, wherein one of the round profiles has at least one stop that can be brought into the area of its runway and inhibits its rolling rotation having. This stop is encompassing as the round profile Sleeve part formed with radially protruding cams and the round profile and the sleeve part have a optionally in bz-. ·. disengageable locking connection together. This simple construction has the advantage that while the table bect is being moved, the Round profile in the sleeve part can rotate, with the jib scraping on the runways, either on the substructure or on the table bed is guided along. Only when the positive connection is brought into engagement, the round profile can rotate the encompassing sleeve part, this rotation now is prevented by the stop. The table bed is then locked in its end position. The sleeve part can for example be designed as a clamp placed around the round profile. However, it is also possible to have a short Piece of pipe to be used as a sleeve part.

The clamp or the pipe is movably arranged on the round profile, ie the round profile \ βζιώ. see turning the sleeve / part, the sleeve part in turn being longitudinally displaceable on the ßundprofile. As a form-locking connection, a receptacle arranged on the sleeve part is provided for a driver arranged radially protruding on the round profile, which can be brought into engagement with the receptacle during the longitudinal displacement movement of the sleeve part, with the stops or cams on the sleeve part then acting to inhibit the rotation of the round profile stand on the underside of the table bed. Of course, these stops can also be in contact with the runway of the substructure.

In a preferred embodiment of the described anti-roll mechanism, the receptacle is axially on the sleeve part arranged pipe pocket, the driver being a dipping into the pipe pocket axially aligned with the round profile Pen is. If the sleeve part is moved in the direction of the pin, this pushes itself into the pipe pocket and at the same time the stops come with the underside of the table bed or the top of the substructure in the knitting system to prevent the round profiles from rotating any further.

An exemplary embodiment of the invention, from which further inventive features emerge, is shown in the drawing shown.

The drawing shows in schematic perspective Representation of the table bed 1 and a rail-like upper part 2 of the substructure. The table bed has at the bottom

a rail-like "projection 3, which is a similar Corresponding projection 4 on the upper part 2 of the lower house facing. The table bed rests on several dog profiles, for which a pipe is used in this example has been. The table bed can be moved relative to the substructure, whereby the tube 5 is attached to the rail-like Projections 3 and 4 on the underside of the table bed and the upper part 2 roll off.

6 with a sleeve enveloping the round profile is referred to, the outwardly radially protruding JLnschlag 7 "and. 8 has, in this embodiment from welded / welded round rods exist. The stops 7 and 8 rest on the rail-like projection 3 on the underside of the table bed. One Rolling movement is possible as long as the sleeve part 6 can rotate freely relative to the pipe. the sleeve part becomes 6 in Moved longitudinally of the tube 5, comes the ax on the sleeve outside protruding tube pocket 9 in engagement with a pin 10 arranged on the outside of the tube, in that this pin is in the pipe pocket is immersed. The sleeve part 6 is thereby rotatably connected to the ear 5, so that further displacement the table beds are then prevented by stops 7 and 8. The table beds filled with earth are of this kind heavy weight that an automatic lifting over the stops 7 and 8 is not possible.
