ABSTRACT:
FIELD AND BACKGROUND OF THE INVENTION
The present invention concerns a combined support device, in particular for an extinguisher, including a frame, a housing for said extinguisher, prehensile means integral with said frame, catching means and means for resting on a plane surface.
In numerous industrial sectors, such as the tinplate industry, plumbing and heating installations, it is necessary to use a torch for various work, such as welding, soldering, oxygen cutting and flame descaling. This work is carried out with a naked flame and can thus involve a significant risk of fire by inflammation of the combustible materials situated in immediate proximity to the torch flame. Moreover, since the torch flame can reach temperatures higher than 3000° C., fires are also liable to be caused indirectly, in particular by sparks or drops of melted metal or the prolonged action of heat radiation, even outside the area of formation of the flame.
Added to these risks is that created by the torch itself when it is not being used. Indeed, operations performed with a torch require frequent interruptions during which the flame is not extinguished. If the torch is then placed carelessly on the floor or on any object acting as a support, it can cause a fire.
This is why it is necessary for the user of the torch to have available, at the place where work is being performed, an extinguisher which he can easily move and a suitable support to place the torch on safely when he is not using it.
OBJECTS AND SUMMARY OF THE INVENTION
The present invention proposes to provide a solution to this safety problem by providing a combined support device as defined in the preamble and characterised in that it further includes means for supporting the torch nozzle and means for insulating the flame of said torch from the environment in which it is situated.
According to the preferred embodiment of the device, the housing for the extinguisher includes several concentric rings and the frame includes two vertical struts to which said rings are fixed at regular intervals.
Preferably, the prehensile means of the device include a handle integral with the vertical struts of the frame and two arms provided with a free bent section at one of the ends thereof. These free sections form the catching means of the device.
The means for placing the device on a plane surface include three legs, two of said legs being formed by the ends of the vertical struts of the frame, and the third being fixed on the rings of the housing at a point which is equidistant from said vertical struts.
In an advantageous manner, the top ring of the housing includes an open sector and the means for supporting torch nozzle include:
an additional ring fixed to the vertical struts of the frame, under the top ring,
a V-shaped notch arranged on the top edge of said additional ring,
and an inverted V-shaped notch arranged on the bottom edge of said ring opposite the V-shaped notch,
said means allowing the torch nozzle to be supported and immobilised when the device is in a vertical position.
In another embodiment, the torch nozzle support means include:
an intermediate element fixed to the vertical struts of the frame between the prehensile means and the housing,
and a groove arranged in said intermediate element for accommodating, guiding and preventing the backward movement of the torch nozzle when the device is in a horizontal position.
Preferably, the means for insulating the torch flame include:
a curved metal plate arranged along the housing over the section thereof comprised between the two vertical struts,
and a layer of insulating material placed in the space defined between said plate and said housing.
