DE1089302B - Extendable and retractable telescopic mast with observer seat arranged on a vehicle - Google Patents

Description

Extendable and retractable telescopic mast arranged on a vehicle with observer seat Arranged on a vehicle, vertically extendable and retractable Telescopic masts are well known.

With these known designs, the mast can be driven in tinge Pivot the state in the horizontal position, so that the vehicle on the one hand when changing location can be moved through narrow door openings, on the other hand also for road transport is not exposed to an impact against an obstacle.

Telescopic masts for observation in the field point at the top of the mast a basket or chair to hold the observer. These mostly firmly with Seating devices connected to the mast prove to be space-blocking during road transport; in addition, the observer lacks the possibility of spreading a map or the possibility of temporary storage of optical devices.

The invention aims to eliminate this deficiency and at the same time make it easier for the observer enable the seat to be pivoted arbitrarily about a vertical axis, but the table is compass-compatible with a map attached to the table top should remain aligned to make it easier to address the observed goals.

According to the invention this is achieved in that the mast tip as A table that can be attached to the upper end of the strut and does not rotate there is formed and that the observer seat a around the geometric axis of the mast pivotably mounted on the table leg forming the extension of the mast Chair is, the chair forms a structural unit with the table.

In a further embodiment of the invention, an upright pin serving to hold the table with the chair is provided on the chassis specifically for the use of the table on trailers, so that the chair can also serve as a seat while driving.

It is recommended to use the on an upright pin of the chassis frame fixed seat in the space between the chassis frame and the one in horizontal Position folded telescopic mast to be arranged.

The invention is illustrated in the drawing and will be on hand of the illustrated embodiment described below.

1 shows a vertically extended observer mast on a trailer vehicle in a view from the side; Fig. 2 shows the same device with the mast pushed together and the observer seat removed from it in the ready-to-drive state in a view from the side.

On the approximately rectangular vehicle frame 1 , two vertically upwardly directed support arms 2 are arranged, which hold the lower telescopic mast part 4 pivotable about the horizontal axis 3. The part 4 is pivoted by means of a pressure cylinder 5 which is supported on the one hand at 6 on the remaining part 4 and on the other hand against the front frame part of the chassis frame 1 . The telescopic mast itself consists of several telescopic parts 4, 7, 8, 9 and 10 . H. At the free end of the tubular mast part 10 there is a plate-like widening 11. This plate-shaped member 11 is engaged by tensioning wires 12 which laterally support the extended mast. On top of the plate-shaped member there is an upright, upright peg 13 which receives a one-legged table with a preferably round table top 14. An observer's chair 15 is fixed to the table leg. The table is connected to the telescopic mast in a torsionally rigid manner, while the chair 15 can be pivoted around the table and can be arbitrarily fixed in any pivot position. It is thereby achieved that a map fastened to the tabletop in a compass-compatible manner can be attached while the observer's seat can change direction at will.

The chassis 1 is braced in a known manner by means of foldable support arms 16 and spindle members 17 in the position of use against the ground.

When changing location, the table with the chair 15 is in the space between the chassis frame and the horizontally aligned, collapsed mast. For this purpose, a special pin is provided on the chassis frame, on which the table with the chair can be placed as a structural unit. In this position, the chair serves as a passenger seat, as illustrated in FIG. 2.

Claims (2)

PATENT CLAIMS: 1. Arranged on a vehicle; Vertically extendable and retractable telescopic mast which can be swiveled horizontally and has an observer seat provided at the top of the mast, characterized in that the mast tip is designed as a table (14) which can be attached to the upper end of the strut (10) and does not rotate there, and in that the observer seat is a pivotable about the geometric axis of the mast on which the extension of the mast forming the table leg is mounted chair (15) , the chair (15) forming a structural unit with the table (14). 2.
