ES2273559A1 - Extinguisher support for auto-descending, automatic activation and modification of probe tube of extinguisher, has tube guides on which probe tube slides in telescopic movement to hold and turn extinguisher according to predetermined axis - Google Patents

Abstract

The support has tube guides on which a tube section of the probe tube of an extinguisher slides in telescopic movement. The support is used to hold an extinguisher and turn the extinguisher according to an axis located below the center of gravity of the extinguisher. The probe tube of the extinguisher is modified to make it work in inverted position in case of automatic activation.

Description

Fire extinguisher stand with auto descent, automatic activation and consequent modification of the probe tube of the extinguisher.

The invention fits within the elements and complementary devices of manual fire extinguishers fire

Currently the manual extinguishers consist, in general, of a body formed by a metal container with a head valve, a projection hose and a support or closet for your location.

This support is usually limited to a hook, fixed to a metal plate that is screwed to the wall, from which Hang the fire extinguisher.

WO 02/15980, WO patents are known. 98/53947, P9002176 and others referring to supports, with different purposes and utilities, for manual fire extinguishers, but none are raises the problem of the descent of the extinguisher or its car automatic descent and activation through its own support.

Manual fire extinguishers, in conditions of use, They have weights ranging between 7 and 14 kg, which means that, for some users or under certain conditions, lifting them for pick up and subsequent use is complicated, both for its weight as per handling and grip system, when not a risk of injuries in its uncontrolled fall if it is possible to lift.

Also, if during a fire there is no user that you use the fire extinguisher, it will end up exploding whenever reached by fire.

The present invention solves both problems effectively through a simple system that allows the user make the rapid descent, at ground level, of the extinguisher without any effort and automatically its descent and activation if the Fire extinguisher is hit by fire.

The support consists of a guide tube, section triangular, square, rectangular or any other appropriate, layered or not at the top and fixed at the end higher than the vertical or horizontal wall where the fire extinguisher and its lower part to the same wall if this end it also becomes angled or to the ground if it is the end straight.

Telescopically inserted into this guide tube, a sliding section of tube, of the appropriate length, with a tongue or hook to hang the fire extinguisher and a pin or mechanism lock that fixes the sliding section to the guide tube so that this section cannot scroll vertically as long as it is not the pin or locking mechanism removed. In the same section you it has an anchoring system such that, when the sliding section passes in its displacement through a housing in the tube guide can exceed it in the downward direction and is anchored in the upward direction.

To avoid the impact, in the free fall of the extinguisher, a system is arranged at the bottom of the guide tube of damping or in the sliding section a braking system Adjustable mechanic

The sliding section can have a vertically rotating platform, containing the extinguisher, with the axis of rotation located transversely to the axis of the extinguisher and by below the center of gravity of the same that allows, during descent or before, the extinguisher rotate around this axis to stand vertically and inverted upon reaching the ground so that, at this time, the firing lever of the fire extinguisher and therefore the Fire extinguisher valve is operated by the extinguisher's own weight, stop and the anchors provided.

The rotation of the fire extinguisher platform is prevented by a plastic pin or any type of fuse thermal so that when it is reached by heat it releases the rotation and the descent of the extinguisher.

The present invention raises a system of clamping, lowering and automatic activation of a manual fire extinguisher that entails, given the proposed automatic activation system of the extinguisher, a modification in the probe tube of the extinguisher that allows to operate in an inverted position.

A manual fire extinguisher internally has a tube probe necessary for its correct operation but to be inverted the extinguisher makes you lose all effectiveness of operation, since in this position the probe tube makes the fire extinguisher only expel the propellant gas but not the agent extinguisher. Therefore it is necessary to modify this probe tube so Whether a descent occurs for manual handling of the extinguisher by a user, as if an activation drop occurs Automatic by temperature, the extinguisher works correctly. This  It is equivalent to saying that the extinguisher has to work both in position Right as inverted.

The modification of the probe tube for this double operation is achieved with a sliding system of cross-open bushings, at the base and neck of the probe tube that allows the extinguishing agent to exit, through the right place, in any position.
tion.

When the extinguisher is reversed, the caps (2) fall by gravity to a new position where the hole lower (5) is covered while the upper hole (1) is uncover In manual operation the propellant gas will boost the extinguishing agent through the lower hole (5) while in automatic operation (position reversed therefore) the gas propellant will propel the extinguishing agent through the drill top (1).

The present invention is illustrated by following examples, which are not intended to be limiting of their scope.

Example one

Support with auto descent (fig. 1): when removing the pin (4) that prevents the descent of the section (5), this descends by gravity along the tube (3) until the shock absorber is reached (9). The rebound is prevented by the nail (7) that has been lodged during the descent into the groove (8) of the tube and that prevents the rise of the section (5). The stop (10) is height adjustable so that it previously adapted to the height of the extinguisher that is placed in the support (6) thus avoiding that when descending you can reach hit the ground.

If a shock absorber (17) is provided on the ground and the height of the stop (10), the fire extinguisher is conveniently fixed after descending you can also be off-hook from your support (6).

Example 2

Support with auto descent and auto drive: the support (16) of the fire extinguisher is shaped like u covering both the base as the head of the extinguisher and has two straps (13) that they hug him at his midpoint. This support (16) has an axis of rotation (14), with respect to section (5), located below the center of severity of the extinguisher so that, if there is no mechanism that prevents it, its stable position is reversed, therefore when jumping fixing pins the extinguisher rotates and descends reaching hit the upper handle of the fire extinguisher valve with the stop from the ground (17), this handle being tight when unable to ascend the sliding section (5) for being locked in the window (8) by the fixing nail (7) and not being able to rotate the support (16) by the turn has been blocked by the mechanism (23) in the lock position (24), therefore the extinguisher.
