COVER ANVIL

1. Field of the invention

The field of the invention is that of construction and building, and in particular that of roofing tools.

More specifically, the invention relates to a roofer's anvil.

The invention finds an application in particular in the size of slates and makes it possible to adapt their dimensions to the constraints of each roof.

2. State of the art

On roofing sites or renovation of slate roofs, it is known to use a roofer's anvil to cut slates according to the different configurations of the roof, for example in the presence of a skylight, or a valley, or at the level of the last row of slate at the ridge or on the bank.

Traditionally, the roofer's anvil is a tool obtained by punching in a flat steel sheet, in the general shape of a "T". The horizontal branch of the "T" forms the body of the anvil, the upper longitudinal edge of which called ford serves as a support for the slate when the roofer places it on the body of the anvil to cut it. Depending on the model, the ford is flat or inclined to form a chamfer which facilitates cutting. Depending on the orientation of this chamfer, the anvil can be used by a left-handed or a right-handed person.

In addition, the body of the anvil is extended by the vertical branch of the "T" which forms the foot or the tail of the anvil. This straight or curved foot has a tapered distal end in the shape of a point. Thus, the roofer can immobilize his anvil by planting the point in a structural element such as a rafter.

Document FR-A-3 012 162 describes such an anvil which has the drawback of damaging and therefore of irreparably weakening the structural element in which the anvil is inserted, by cutting the fibers of this element.

Another disadvantage of a known "T" anvil is that it is not possible to plant your foot when the roofer intervenes to repair an already covered roof area. This is why, by default, the roofer plugs the anvil into an upright of the wooden roof ladder that he uses. Roofer ladders are made up of uprights of great length and thinness. Thus, they are flexible, essential characteristics which allow them to marry the roof and distribute the load which avoids localized supports which would damage the roofing, but are not very robust. So, planting the anvil in the ladder will weaken it.

In order to remedy these drawbacks, it has been proposed in document FRA-2 627 226 to integrate a tool holder with a roof ladder. This tool holder mounted at the level of the upper rung and on the outside of the ladder has a slot which makes it possible to wedge the end of the anvil tip. Thus, the roofer can in certain cases avoid planting the anvil in the ladder or the frame.

A disadvantage of this tool holder technique is that if the ladder has a length of 5 m or more, the tool holder is not necessarily located in the work area of the roofer.

We thought of adding tool holders regularly along the length of the ladder. But these weigh down the scale which is already not very handy and is expensive.

These known techniques also have the disadvantage of not solving the problem of using the anvil on the ground which requires a workbench or a piece of heavy and stable wood. Indeed, for certain repetitive cuts, such as the size of a batch of shore slates all at the same length, the roofer prefers to work on the ground in safety rather than in balance on a roof.

3. Objectives of the invention

The invention therefore aims in particular to overcome the drawbacks of the state of the art cited above.

More specifically, the invention aims to provide a roofing anvil for the size of slates which can be used without planting it in a frame member or ladder.

Another objective of the invention is to provide such a roofing anvil technique which is simple to use on a roof, and / or on the ground, which makes it possible to work in safety and in particular which is easy to handle and ergonomic.

Another object of the invention is also to provide such a roofing anvil technique which makes it possible to store a few slates in reserve on the roof.

Another objective of the invention is to provide such a roofing anvil technique which offers a solution for allowing the tracing of the cutting line to be produced on the covering element.

An objective of the invention is also to provide such a technique which is of reduced cost price.

4. Statement of the invention

These objectives, as well as others which will appear subsequently, are achieved with the aid of a roofing anvil for the size of a covering element such as a slate, comprising a substantially quadrilateral planar body having a longitudinal cutting edge. .

According to the invention, such an anvil has at least one hanging hook projecting from the longitudinal edge opposite the cutting edge, the hook being oriented in a direction substantially parallel to the edge.

Thus, it is possible to maintain the anvil on different supports such as structural elements, a slate hook, the flat roofing ladder, without irreparably damaging the supports in question.

In addition, it is also possible to use the anvil placed directly on the ground.

In addition, to move it no effort is necessary, unlike an anvil of the prior art that must be torn from the support in which it is inserted.

Furthermore, the cutting edge and the opposite longitudinal edge are not necessarily parallel.

In a particular embodiment of the invention, the planar body is substantially trapezoidal or rectangular.

According to a particular embodiment of the invention, the hooking hook is secured substantially at one end of the longitudinal edge opposite the cutting edge.

Thus, the hook offers, at the end of the anvil a bearing surface on which the roofer can retain and store a few slates to be cut.

According to a particularly advantageous embodiment of the invention, the hanging hook has an end folded in the shape of a "U".

Thus, the hook can be slid over the batten or the bar of the ladder, a leg of the "U" passing behind it, which makes it possible to secure the hooking and to prevent the anvil from coming off the support. under the impact of sudden shocks when cutting roofing elements, such as slates.

According to a particular embodiment of the invention, the opening of the hook is adapted so as to allow the anvil to be hooked to a structural element, such as a batten, to a slate hook or to a step of a roofer's ladder.

Thus, the opening of the hook is particularly suitable for cooperating with the possible attachment points on a roof, such as a slate support strip on a roof, or a rung of a flat roofer's ladder.

For example, the opening of the hook may be greater than or equal to 15 mm, advantageously greater than or equal to 19 mm, for attachment to commonly used battens whose thickness is either 14 mm or 18 mm. Preferably, this opening of the hook is greater than or equal to 29 mm, allowing it to be hooked on most of the ladder bars whose thickness is generally 25 mm.

According to a preferred embodiment of the invention, the roofer's anvil has two hooking hooks projecting from the longitudinal edge opposite the cutting edge.

Thus, the roofer always finds on the roof a point of attachment adapted to the use of his anvil.

In addition, when the anvil is hung on slate hooks on an already covered part of the roof, the two hooks of the anvil provide a greater bearing surface which better distributes the forces undergone by the anvil during slate size.

In addition, this also prevents the end of the anvil body, opposite the hook, from sinking into the ground when it is used on the ground.

Preferably, each of the two hooking hooks is secured substantially to one or the other of the ends of the longitudinal edge opposite the cutting edge.

Thus, the anvil is more stable, especially when used on the ground.

According to a particular embodiment of the invention, the anvil comprises means for adjusting the spacing between the two hooks along the longitudinal edge opposite the cutting edge.

Thus, it is easy to adjust the distance between the two hooks according to that between two battens of the frame, or two bars of the roof ladder for example.

According to an advantageous embodiment of the invention, the anvil body has at least one lumen configured so as to allow the passage of at least the distal phalanx of a finger of one hand.

This makes it easier for the roofer to handle his anvil because he can grab it with a finger.

In addition, he can hang it on his harness, using a carabiner for example, to free a hand and thus climb and move on the roof safely.

According to a particularly advantageous embodiment of the invention, the anvil has four substantially aligned lights, configured so as to each allow the passage of at least the distal phalanx of a finger of one hand.

Thus, the roofer can fully grasp his anvil, and distribute the weight of it on the four fingers which reduces his fatigue.

According to a particular embodiment of the invention, the four lights have in pairs a center distance of substantially 34 mm.

Advantageously, the lights have a parallel axis and spaced approximately 45 mm from the longitudinal edge opposite the cutting edge.

Thus, the palm of the roofer's hand is in contact with the longitudinal edge opposite the cutting edge, the edges of which can be broken, unlike the cutting edge which comprises at least one sharp edge.

According to a particular embodiment of the invention, the cutting edge is bevelled on one side over a substantial part of its length.

Thus, the cutting edge includes a sharp edge which promotes cutting. The side where this sharp edge is formed determines the side where the hammer must shear the roofing element and therefore which hand the roofer will work with. Such anvils are therefore intended either for left-handers or for right-handers.

According to a particular embodiment of the invention, the longitudinal edge is separated from the cutting edge by a distance greater than or equal to 100 mm, preferably greater than or equal to 125 mm.

Thus, the roofer has enough space between the support such as the roof and the cutting edge to use his anvil as a rule and draw the cutting line to be made. To do this, he places his slate on the cutting edge and uses a tool, such as his hammer, which he slides between the anvil support and the slate along the cutting edge.

Preferably, the cutting edge has a length substantially of 400 mm.

Advantageously, the two hooks are spaced substantially 330 mm apart, which corresponds to a typical distance between two steps of a roofer's ladder.

6. Detailed description of the invention

6.1. Example of embodiment of the invention

Illustrated in Figures 1 and 2 is an exemplary embodiment of a roofing anvil 10 according to the invention intended to be hung, for example on a roof ladder or a structural member, without damaging it.

This roofing anvil 10 comprises a substantially rectangular body 11, one longitudinal side of which called ford 12 serves as a cutting edge. This body 11 includes three rounded corners to prevent the roofer from injuring himself.

On the longitudinal edge 13 opposite the ford 12 are welded at each end, two hooks 14 and 15 of identical orientation, a hook 14 said upper present at one end 16 of the anvil 10 and a hook 15 said lower.

Each hook 14, 15 is substantially in the shape of a "U" with asymmetrical jamb. As can be seen, the longest leg 14a, 15a of each hook 14, 15 substantially forms a triangle to lighten the weight of the anvil. It is on the height of the isosceles triangle of the longest leg 14a, 15a, that the longitudinal edge 13 of the body 11 is fixed by a continuous weld bead. Furthermore, the second leg 14b, 15b of each hook 14, 15 is substantially rectangular for a maximum gripping surface on the attachment support. In addition, the dimension of the surface of the second leg 14b, 15b is important for the stability of the anvil, especially when it is used on the ground.

Furthermore, the upper hook 14 and the end 16 of the body 11 form a bearing portion on which it is possible to keep a few slates in reserve on the roof.

In Figure 1, we also see the presence in the body 11 of four lights formed of holes 17 regularly spaced, adapted to the passage of at least the first phalanx of the fingers of the hand of the roofer, for handling the anvil. These holes 17 are located near the longitudinal edge 13, the edges of which are broken to prevent the user from being injured.

In this exemplary embodiment, the anvil is made of galvanized steel. Its body 11, forming a rectangular plane of substantially 400 mm x 125 mm for a thickness of 4 mm comprises three rounded corners with a radius of 10 mm. With 125 mm of distance between the ford 12 and the longitudinal edge 13 opposite the ford, the roofer can pass a tool such as a point to be traced between the slate placed on the ford and the support such as the ladder or the roof for mark the cutting line by sliding the tip along the cutting edge.

Along the longitudinal edge 13, the hooks 14, 15 are spaced substantially 330 mm apart.

In addition, each hook 14, 15 in the shape of a "U" formed in a 3 mm sheet has an opening of approximately 29 mm, for a useful depth of approximately 29 mm and a width of approximately 100 mm. Each triangular leg 14a, 15a has a height of substantially 64 mm for a base of substantially 100 mm.

Furthermore, the holes 17 of the finger pass, with a diameter substantially 24 mm and substantially equidistant from 34 mm, are located on an axis approximately 45 mm from the longitudinal edge 13.

6.2. Other optional features and advantages of the invention

In variants of the embodiments of the invention detailed above, provision may also be made:

integrating means for adjusting the position of one or more hooking hooks, such as a screw with a wing nut, the screw secured to the hook being able to slide in an oblong slot in the body of the anvil, for example;

make a cutting edge or at least partially bevelled edge on one side to obtain a sharp edge facilitating cutting, for a left or right handed user, depending on the orientation of the bevel;

to produce a quadrilateral body in which the ford is not parallel to the opposite longitudinal edge, in particular so that the ford has on the roof a slope less than that of the opposite edge parallel to the roof and thus facilitate the tracing of the slate in support on the ford from below along the ford;

integrate a slate retaining plate, substantially in the extension of the upper hook, at the end and perpendicular to the body of the anvil.
