Abstract

Dans la présente invention, un orifice a été fait sur la partie extérieure d'un coude de tuyau de poêle ce qui permet de nettoyer le tuyau de poêle sans avoir besoin de le démonter. Cet orifice est fermé par une trappe retenue fermement au coude pa r une penture à ressort d'un côté, et par une agrafe de l'autre.In the present invention, an orifice has been made on the outside of a stove pipe elbow which allows the stove pipe to be cleaned without the need to dismantle it. This orifice is closed by a hatch held firmly at the elbow by a spring hinge on one side, and by a clip on the other.

II est d'usage courant pour nettoyer le tuyau : que le poêle soit refroidi pour dévisser les vis, de se munir d'un contenant pour recevoir les résidus, de faire suffisamment attention de ne pas trop salir la résidence et finalement, remonter le tout. Cette méthode nous apportait d'autres inconvénients comme le centrage des trous de vis après le tuyau sans parler du temps alloué, soit de trente à quarante minutes, et enfin, rallumer le poêle.
f ai découvert que ces inconvénients peuvent être supprimés en perforant un orifice du côté extérieur d'un coude de 90 degrés (6) et en recouvrant ce trou par une trappe (4), celle-ci légèrement plus grande que le trou.
La trappe (4) est retenue fermement au coude par une penture à ressort (3) et se ferme hermétiquement car il est muni d'une agrafe autoblocante mâle (2) qui s'unit à
la partie femelle (5) déjà existante sur le coude de 90 degrés (6) et pour que tout se fasse vite j'ajouterais un anneau (1) d'environ un pouce pour que l'accès d'ouverture soit rapide.
Pour nettoyer les conduits du poêle qui sont en ligne droite avec le coude 90 degrés (6), il s'agit de tirer l'anneau (1), d'ouvrir la trappe (4) qui reste attachée au coude grâce à la penture (3). Ä l'aide d'un grattoir, on nettoie les conduits. Lorsque le nettoyage est terminé, nous refermons la trappe (4) et nous poussons légèrement vers le coude (6) pour que l'agrafe (2) s'unisse à la partie femelle (5) et y prenne prise.
Grâce à la penture (3) et à l'anneau (1), le travail est fait rapidement et la trappe (4) est toujours bien ajustée au coude (6).

It is common practice to clean the pipe: let the stove be cooled to unscrew the screw, get a container to receive the residue, make enough attention not to soil the residence too much and, finally, reassemble everything. This method us brought other disadvantages such as the centering of the screw holes after the hose without talk about the time allotted, thirty to forty minutes, and finally turn it back on the stove.
I discovered that these disadvantages can be eliminated by perforating a orifice of outer side of a 90 degree elbow (6) and covering this hole with a hatch (4), this slightly larger than the hole.
The hatch (4) is held firmly at the elbow by a spring hinge (3) and closes hermetically because it is provided with a self-locking male clip (2) which unites with the part female (5) already existing on the 90 degree elbow (6) and so that everything is be quick I would add a ring (1) of about an inch so that the opening access be fast.
To clean the stove ducts which are in a straight line with the elbow 90 degrees (6) there this involves pulling the ring (1), opening the hatch (4) which remains attached to the elbow thanks to the hinge (3). Using a scraper, the ducts are cleaned. When the cleaning is finished, we close the hatch (4) and we push slightly towards the elbow (6) for that the clip (2) joins the female part (5) and takes hold there.
Thanks to the hinge (3) and the ring (1), the work is done quickly and the hatch (4) east always well adjusted at the elbow (6).

Claims

Claim:

1. An access hatch for cleaning a stove pipe having an opening on the outside with a 90 degree elbow of said pipe, said hatch covers the orifice and marries the shape of the part exterior of said elbow to allow sealing, said hatch is characterized by:
an oval shape and radii of curvature along the longitudinal axes and transverse of said bend, the longitudinal axis of the hatch is arranged parallel to the axis longitudinal of the elbow;
the hatch is the same thickness and material in corrugated sheet as the elbow;
at one end of the hatch, a ring is screwed to the external wall of said trap;
an arrow-shaped male part of a self-locking staple is screwed to the inner wall of the hatch;
a female part, square or diamond-shaped, corresponding to the male part of said staple is pierced on the wall of said elbow;
said ring has a circular shape of an inch size and is used to rotate the hatch to access said elbow opening; and attached to the elbow and the opposite end of the hatch, a spring hinge firmly holds the trapdoor at the elbow and allows rapid closing of the trapdoor.
