Abstract

A universal job centre is composed of a working plate (1), where brackets (2) having shafts (8) are secured on opposed side edges, said brackets being intended to receive hoops (3, 4) which are pivotable around the shafts in an angular range of 270°. Preferably, the hoops may be locked in three positions, which are positioned such that the hoops are either flush with the lower edge of the working plate, or so that the hoops point out from one of the surfaces of the working plate. When the hoops are locked in these positions, the job centre may be converted from being a sack truck (1) into being a working table (2), a roller board (3), a transport cart (4) and, if steps are provided between the hoops, a ladder.

Description

A job centre and uses thereof
The invention relates to a job centre comprising a working plate on whose one surface a plurality of wheels are mounted, and wherein brackets having shafts are arranged on two opposed side edges of the working plate, said brackets having mounted thereto hoops which are pivotable around the shafts.
The invention moreover relates to uses of the job centre.
Many job centres have been developed through the years for artisans, such as job centres consisting of sack trucks which may be converted into a scaffold, a ladder or the like, e.g. as described in GB 1 519 956.
As described in the GB document, the job centre is composed of a ladder which is connected at the top with a plate, which is provided with two hoops, where one hoop is connected with the ladder and the hoop, while the other hoop is connected with the opposite end of the plate. This known job centre consists of many parts and brackets, which makes it rather costly to manufacture the job centre. Further, the weight of the job centre will be quite high.
Finally, US 2003/0234517 A1 discloses a trolley which is equipped with a pivotable hoop which may be adjusted to various angular positions.
Accordingly, an object of the invention is to provide a job centre which, in addition to being flexible, consists of few parts.
The object of the invention is achieved by a job centre of the type defined in the introductory portion of claim 1 , which is characterized in that the hoops may be adjusted to several positions within an angular range of 270°. Hereby, a job centre is provided, which consists of few parts, while maintaining flexibility, it being possible, merely by pivoting the hoops, to convert the job centre into a working table, a transport cart, a sack truck, a ladder or a roller board.
To ensure the stability and the flexibility of the job centre, it is advantageous, as stated in claim 2, that the brackets are formed with recesses which are adapted to receive locking pins on the hoops.
For simple adjustment and locking of the hoops to the bracket, it is advantageous, as stated in claim 3, that the hoops have a guide slot so that the hoops may be displaced perpendicularly relative to the shafts, and additionally, as stated in claim 4, that a spring is arranged in the guide slot between each of the shafts and the bottom of the guide slot.
In order to strengthen the job centre, it is an advantage, as stated in claim 5, that a metal plate is arranged between the legs of the hoops, which may alternatively be done, as stated in claim 6, in that ladder steps are arranged between at least one of the hoops.
As mentioned, the invention also relates to uses. These uses are defined in claims 7 - 10.
The invention will now be explained more fully with reference to the draw- ing, in which
fig. 1 shows the job centre as a roller board,
fig. 2 shows the job centre as a sack truck,
fig. 3 shows the job centre as a transport cart, fig. 4 shows the job centre as a working table,
fig. 5 shows a bracket which is used in the job centre,
fig. 6 shows how one side of a hoop is coupled to the bracket of fig. 5,
fig. 7 shows the structure of the bracket in fig. 5 and fig. 6,
fig. 8 shows the job centre in fig. 4 in perspective,
fig. 9 shows the job centre in fig. 3 in perspective, while
fig. 10 shows the job centre with a circular saw during transport, seen in perspective.
In figures 1 - 4, the numeral 1 designates a working plate which is provided with wheels 5 on its one side.
Brackets 2, whose structure will be explained more fully in connection with figures 5 - 7, are secured along two side edges of the working plate. These brackets carry hoops 3, 4 which, as may be seen in the figures, may be positioned in various angular positions relative to the surface of the working plate, so that the job centre may be used as a roller board (fig. 1), as a sack truck (fig, 2), as a transport cart (fig. 3 and fig. 9) and as a working table (fig. 4 and fig. 8).
With reference now to figures 5 - 7, it will be explained how the brackets 2 are composed.
The bracket 2 carries one leg of a hoop 3, there being arranged through the bracket a shaft 8 around which the hoop is pivotable. The bracket itself, cf. fig. 7, is formed by a component which consists of a profile 14 and a plate member 15 which carries the shaft 8. The profile 14 and the plate member 15 are secured to an edge on the working plate 1.
The hoop 3 is equipped with a guide slot 9 so that it may be displaced relative to the shaft 8.
One end of a spring 10 is mounted inside the bottom 12 of the hoop 3, while its opposite end is secured to a fixed bracket part 11. The spring 10 will secure the hoop 3 in the position shown in figures 5 and 6, where a locking pin 13 on the hoop 3 is mounted in a recess on the bracket 2, which is designated Pos. A.
If a pull is now applied to the hoop 3, it will be displaced in the guide slot 9 and will clear the recess Pos. A, following which the hoop may be pivoted around the shaft 8 to one of the other positions, which are designated Pos. B or Pos. C, where the spring will secure the hoop in the recess of the these positions.
Hereby, it is possible to adjust the hoop within an angular range of 270° in the three positions Pos. A, Pos. B or Pos. C, so that the job centre may be converted to the uses explained previously.
A metal plate (not shown) may be secured between the legs of the hoops, so that the job centre becomes more stable.
It is also possible to secure ladder steps (not shown) between the legs, so that the job centre may serve as a ladder.
