Abstract

The device is for cutting wood especially several logs of wood and comprises several baskets (6) in which the wood is piled. The wood is elevated to a certain height for the mounts (4) on a base (1) stabilised by parts (2). The baskets (6) may be removable and the feet of the baskets are placed in holes in plates (5). There may be parts (8) which are fixed transversely over the baskets (6) allowing anchoring for the holding of the wood.

Description

DESCRIPTION
Cut-off easel with removable baskets
The present invention relates to a device for cutting with a minimum of effort and a maximum of security several logs of wood in a single operation.

 The traditional easels called cross or goat are ill-suited to the use of a chainsaw; others, more sophisticated, are more reassuring but often costly and ineffective. The wood is most often cut log by log and the operator must collect the cut wood from the ground.

 The device according to the invention makes it possible to stack and enclose several logs of wood at a comfortable working height in order to be cut into thirty three centimeters or fifty centimeters.

 The operator can work alone with maximum safety and in an ergonomic position.

 The fact of being able to cut several logs together causes on the one hand a saving of energy necessary for the operation of the chainsaw, on the other hand a reduction in noise pollution and avoids untimely handling of the wood between two cuts.

A safety bar prevents accidents at the end of the cut.

 The device according to the invention also prevents the user from picking up the cut wood on the ground, in fact the baskets in which the wood has been stacked and cut are removable and allow the operator to return the wood to the desired location by simply removing the said baskets from the frame which remains at the cutting location.

 The entire device can be easily moved when empty using a central wheel on one side of the frame (wheelbarrow style).

The device according to the invention consists of four separate parts
- the base and its two stabilizers shaped in metal profile.

 - platinum support uprights fixed at certain locations on the base.

 - baskets in metal tubes fitting into the plates and in which the wood is stacked.

 - A safety bar preventing accidents at the end of the cut.

Detailed Descriptions
The accompanying drawings illustrate the invention
Figure 1 shows the dispoSitif according to the invention from the front equipped with three uprights (4) fitted and screwed into profiles (3) welded on the base (1) at a center distance (a) for cutting wood in thirty three centimeters .

The center distance (b) allows the wood to be cut in fifty centimeters using only two uprights (4) fitted and screwed into profiles (3) welded to the base (1).

 the user just has to cut between two baskets (6) to achieve the length of the desired wood. The wood is shown in the figures in (17). The saw cut in (18).

Figure 2 shows the device according to the invention from another angle and shows the fixing of the stabilizers (2) on the base (1).

These stabilizers are equipped at each end of the cup (11) adjustable in height by screwing allowing the leveling of the entire device.

Figure 2 also shows the location of the safety bar (13) shaped in the tube, and its attachment to uprights (12) which even come to be fixed on the parts (2), screws perfect their maintains.

Figure 3 shows the baskets (6) formed in metal tube. These baskets are composed of two identical parts (6) and (6 ') bent into a certain radius corresponding to the distance between the holes on the plate (5). These two parts are joined by a piece (7) by welding, of a length allowing the concordance of the centers in the other direction of the plate (5). The parts (7) form a stop on the plates (5) when the feet of the baskets are fitted therein.

Plastic plugs (10) act as feet, the baskets can be placed inside the house without damaging the floor.

 Iron sleepers (8) are fixed by screwing on (6) and (6 ') perpendicular to the pieces (7) and at a certain height.

On the one hand to stiffen the basket assembly and on the other hand to allow the attachment of an elastic tensioner (9) Figure 1 and Figure 2 for the maintenance of wood during and after cutting.

The plates (5) formed in the metal sheet of sufficient thickness are welded in their axis to the uprights (4).

 Figure 4 shows the fixing of the wheel support (14) on a stabilizer (2) by welding. The wheel (15) is made of plastic rotating on an axis (16) fixed on either side of the support (14) by screwing.

 The wheel is located in the axis of the base (1) and slightly raised from the ground. It is enough to raise the side opposite to it to make it touch the ground and thus move the device empty like a "wheelbarrow". The wheel attachment does not appear on the other diagrams for a good understanding when reading the plans.

Notes: It is possible to make the packaging of the device more practical and less bulky to make the baskets (6) removable.

It suffices to section the parts (7) in FIG. 3 through their middle and to sleeve them using a tube with an outside diameter corresponding to the inside diameter of the parts (7), then pierce the assembly and screw. It is the same for the uprights (4) and their plate (5),
It is sufficient to weld a profile identical to the parts (3) in FIGS. 1 and 2 under the said plates on their axis and to perfect the maintenance of the uprights (4) by drilling and screwing.

 It is obvious that the device according to the invention can be used to cut boards, bundles and all materials which can be normally cut by a chainsaw or a hand saw.

Of course, the invention is not limited to the embodiment described above and shown from which one can provide other modes and other embodiments without departing from the scope of the invention .
