Description.

Denominations.

Shelf with brackets for use on ladders.

The scope of production.

This provision relates to a shelf with brackets for ladders, for use in connection with the placing of tools and tools, and for use as support for the ladder against house walls or roof hangings.

The shelf is provided with a bracket which attaches to two of the ladder steps, the bracket thus being designed to lock itself after application to the ladder steps, thus remaining fixed regardless of the effects.

The shelf is mounted on the brackets. The fittings are designed with an elasticity to fit most known types of ladders.

Prior art.

IUS 4211307 is shown a shelf for ladders with suspension and brackets.

The bracket is fastened in 3 consecutive steps, with the shelf suspended in the upper stage and adjusted in the transverse direction over the middle stage, and supports on the lower stage.

The middle step bracket enables positioning in a position in front of the ladder, as well as at the rear of the ladder.

IGB 1179970 is shown a shelf with brackets for use on ladders.

The technical problem to be solved.

The known shelves with fittings US 4211307 and GB 1179970 are inappropriate in use, resting on the steps of the ladder, without proper attachment. This means that an upward impact can release the bracket from the ladder, thus reducing the shelf.

In addition, GB 1179970 has the disadvantage that it can only be mounted on the back of the ladder.

The known shelves have fittings that are expensive and complicated to manufacture.

The new technique.

What is new in the invention is that a bracket is designed in two parts so that after mounting it is fixed so that it is able to withstand influences from all directions without being released from the steps of the ladder. The shelf is mounted on these two fittings.

Shelf with brackets can be mounted at the front or rear of the ladder as desired.

The technical impact.

By using said technique, where the brackets are self-locking on the ladder steps, together with prior art, it is obtained that shelves with brackets can be fixed on the ladder steps so that it can withstand forces from all directions, and of normal sizes, without being released off the ladder, thereby falling down.

To release the shelf fittings from the ladder steps, the fittings must be influenced by 3 simultaneous and independent influences.

The fittings are simple and inexpensive to manufacture, as the processing consists of cutting, drilling holes, and bending.

Exports Examples.

Figure 1 shows shelf with bracket (1) on which shelf (2) is mounted on bracket (3).

Bracket (3) (2) is fastened with bracket (10) to "front" of ladder (4), with shelf (2) pressed against the front edge (7) of brackets (6). the clip onto ladder stage (5).

In FIG. Figure 2 shows shelf with bracket mounted on the "back" of the ladder with bracket (9) at the top and bracket (10) at the bottom.

In FIG. 3 shows shelf with bracket (1) where shelf (2) is fastened to bracket (3) with wood screws (8) and where bracket (3) is fixed on ladder steps (4) and (5).

In FIG. 4, detail of bending (9) is shown on bracket (3) indicating angles and dimensions, angle (w) being preferably <90 ° and angle (v) being about 5 °, causing (D) to be about 5mm. greater than (L). Enlightenment (L) is adapted to ten! diameter of common ladder steps.

The bracket is made with thickness (t) and width (b) - see figure 1.

Claims (2)

1.
