Abstract
A device for holding a mechanical tool for forestry work such as a chain saw comprises a combination of a stand (1) and a holding arm (2) which allows the machine to be held at a height from the ground in such a manner that the centre of gravity of the device and machine is inside the support frame outline. <IMAGE>
Description
NEW DEVICE FOR HOLDING A MECHANICAL TOOL FOR
GARDENING, FORESTRY OR RELATED ACTIVITIES
This invention relates to a new device whose purpose is to hold a mechanical tool for gardening or forestry, such tool being in the form of a chain saw.
When a chain saw is used, the saw needs to be frequently out of use for periods of time whilst the sawn timber is moved or fresh timber collected. Generally the saw will be put on the ground and a non electric motor saw, when placed on the ground with the engine running, tends to "walk" about the ground. The machine can under some circumstances overturn. Sometimes the engine will not run smooth or idle slow enough and the chain will catch the ground. This causes the chain teeth to go blunt quickly. During the work sessions, the machine has to be frequently stopped and restarted due to the danger of having a vibrating running machine especially on rough ground.
The purpose of this invention is for a device which holds the chain saw in conditions of safety, with or without the engine running whilst the saw needs to be put down.
The invention concerns a device for holding a mechanical tool for gardening or forestry work, which comprises of a stand, which is on the floor and holds the machine within the framework, above the ground, even on rough or inclined ground.
The device is a combination of hanging and base embers to provide a convenient height for the users. It should be noted that the whole hanging part and the frame forms a combination for the final result for the stability of the whole in a normal rough ground environment.
Thus, according to the invention, the stand and the hanging means rust be sized so that when the machine is in position, the centre of gravity is within the frame legs.
The hanging arrangement allows for the easy fixing of a machine.
For example, if two hooks are used these have to be between 100/ eO(Xrm apart, to allow the users hand to pass between the hooks.
The specific details of the invention will now be described by way of an example with reference to the accompanying drawing, in which:
Figure 1 shows an elevation.
Figure 2 shows a plan.
In this specific example, the stand is made from steel tube (1) of 30mm diameter and 1400mm long, bent in the middle to 90 thus making a right angled triangle, the last side of the base not being closed. The holding arm (2) is 500mm high and 35amm long and perpendicular to the base frame. Two hook bolts (5) bent to approximately SQirn diameter and fixed to the horizontal holding arm (2), such that when a machine such as a chain saw is attached, the machine hangs true, level and horizontal to the ground.
The above device description is only given as an example. It is understood that any variation of design enter into the scope of the invention.
Thus, the stand may have a different shape other than a triangle, may be square, circular, or any other shape. The arm arrangement could be different shapes, as long as the centre of gravity of the device oorresponds to the centre of gravity of the whole when the machine is fitted.
The stand and support arm in the example are made from a tubular section. It is clear that the scope of the invention covers for all other cross sections. For example, rectangular or square section. Also the material may be a metal like mild steel, or aluminium, but could be an alloy, any ferrous or non ferrous material, or in fact a material such as plastic. In the latter case, the design would have to be such as to maintain the solidity and stability compatible with the weight of the machine or tool. The design structural calculations have not been detailed within the present description.
The stand could be equipped with means of securing to the ground.
The device could be capable of being dismantled to make transport and storage simple. For example the support post (2) could be bolted to the stand (1) at plate (3).
The arms of the base (1) could be detachable from the corner piece by female/male connectors with spring push buttons to secure into place. Any method of joining the composite parts is covered by the scope of the invention.
As can be seen from the preceding description, the invention is particularly convenient as the machine (tool, chain saw) is firmly held in the normal manner until such time as the operator has placed the handle of the machine (tool, chain saw) over the securing hook bolts, whence the machine is then released from the operators grip.
Most chain saws have an L shaped handle, as they can be used for sideways as well as vertical cuts. When the saw is in the stand it can be turned sideways for fuelling with oil and fuel.
Normally fuelling would take place with the engine off.
The stand can also be used for working on the machine (tool, chain saw) as the machine is clear of the ground and accessible all round for dismantling.
After maintenance or fuelling the machine can easily be brought round 90 to park in the normal place, with the saw blade width vertical.
The device according to the invention is particularly suitable for a chain saw, but could be used for similar tools used in gardening, forestry, horticultural or agricultural fields, as well and generally in any area where such a tool has to be held in the hands and put down frequently in the oourse of a work session.
Claims (5)
1) A device for holding a mechanical tool for gardening/forestry
work, which comprises of a combination of stand on the ground
and a means whereby the machine (tool, chain saw or the like)
is held at a certain height above ground level, in such a
manner that the centre of gravity of the device and machine
is within the framework, even on uneven ground.
2) A device according to Claim 1 in which a holding method is a
means of hanging and lifting.
3) A device according to Claim 2 in which the hanging means are
two hooks.
4) A device according to Claim 3 in which the two hooks are
between 12oonTn apart.
5) A device according to Claim 1 in which the stand and/or posts
are demountable.
6/ A device according to Claim 5 in which male pieces may be
inserted into female pieces by means of spring buttons which
may be pushed into holes into corresponding female pieces.
