1. Field of the Invention
The subject matter of the present Invention is a shingle, in particular roof shingle, wherein the shingle is characterized relative to the state-of-the-art in that both the laying speed as well as the placing precision are jump-like improved.
2. Brief Descriptions of the Invention
The shingle according to the present Invention, in particular the roof shingle, is characterized in that the shingle exhibits a raised engagement and guiding element at its bottom side. According to a preferred embodiment both the raised guide element as well as the so-called shingle shoulder exhibit undercut zones, wherein the undercut zones correspond to each other. Here the undercut zone in the raised engagement and guide element is formed like a female mold or stencil and the undercut zone in the shingle shoulder is formed like a male mold.
Shingles, in particular roof shingles, can be produced out of a variety of materials, for example out of mineral material, out of wood and more recently in a preferred degree out of a molten mixture of organic material, for example plastics and inorganic material, for example slate flour.
The shingle neck defines an axial direction.
A first shingle shoulder is disposed on a first side between the shingle neck and the shingle body. A first ridge forms a top side of the first shoulder.
A second shingle shoulder is disposed on a second side between the shingle neck and the shingle body. A second ridge forms a top side of the second shoulder. A raised engagement and guide element is disposed on an inner side of the shingle body and in a lower region of the shingle body and disposed remote from the shingle neck and forms a ledge. The inner side of the shingle defines a first plane. An outer side of the shingle defines a second plane disposed parallel to the first plane. The shingle neck defines an axial direction. A plurality of sectional planes is disposed perpendicular to the first plane and contain a straight line disposed parallel to the axial direction of the neck. An inner side of the raised engagement and guide element defines a third plane disposed parallel to the first plane. The ledge forms a third acute angle with the third plane when intersected by one of the plurality of sectional planes. The ledge forms a third obtuse angle with the first plane when intersected by one of the plurality of sectional planes.
The first ridge forms a first acute angle with the second plane when intersected by one of the plurality of sectional planes and the first ridge forms a first obtuse angle with the first plane when intersected by one of the plurality of sectional planes. The second ridge forms a second acute angle with the second plane when intersected by one of the plurality of sectional planes and the second ridge forms a second obtuse angle with the first plane when intersected by one of the plurality of sectional planes.
The first acute angle is from about 40 to 50 degrees. The second acute angle is from about 40 to 50 degrees. The third acute angle is from about 40 to 50 degrees. The first obtuse angle is from about 130 to 140 degrees. The second obtuse angle is from about 130 to 140 degrees. The third obtuse angle is from about 130 to 140 degrees.
The shingle comprises essentially the shingle body, the shingle neck and the shingle shoulder as will be explained and illustrated in detail further down by way of drawings.
The shingle can further exhibit gutter canals on the upper side of the shingle neck as is known in principle.
The shingle is suitable for covering arbitrary surfaces, in particular roof surfaces.
As already recited above, the laying technology can be improved in multiple directions and jump-like upon application of the invention shingles, wherein during laying each shingle assures simultaneously the restraint and restricted guidance of a shingle placed in the following. In addition, the desired positioning is necessarily obtained during laying and the necessary double covering is assured. The essence of the present Invention is explained in detail in the following by way of the accompanying figures, wherein these figures represent preferred embodiments of the present invention.
The novel features which are considered as characteristic for the invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawing.
In the accompanying drawing, in which are shown several of the various possible embodiments of the present invention:
The invention shingle is designated with the reference numeral 1 in
The raised engagement and guide element disposed preferably in the lower region of the shingle body carries the reference numeral 5 with the female mold like undercut zone 6.
The male mold like undercut zone of the shingle shoulder 4 carries the reference numeral 7.
Here the female mold like undercut zone 6 is a rear undercut with re-entrant angle, which female mold like undercut zone 6 serves for receiving the male like undercut zone 7 of the shoulder 4, wherein the male mold like undercut zone 7 is formed nearly sharp edged.
The side 4 is situated in an angle of from about 40 to 50 degrees relative to side 2.
The male mold like undercut zone 7 of the shoulder 4 is situated in an angle of from about 40 to 50 degrees relative to a face of the shingle body 2. The female mold like undercut zone 6 is disposed perpendicular to the face of the raised engagement and guide element 5. Alternatively, the female mold like undercut zone 6 is disposed at an angle of from about 40 to 50 degrees to the face of the raised engagement and guide element 5 such a to shape match the male mold like undercut zone 7.
The geometric kind of the undercut zones 6 and 7 is furnished such at any rate that a slipping in of the male mold like undercut zone 7 into the female mold like undercut zone 6 is performed as complete as possible.
Here the width of the shoulder 4 is preferably dimensioned such that the width of the shoulder 4 corresponds to half the width of the raised engagement and guide element 5.
The roof is laid from the bottom to the top during the placement work in such a way as this is shown in detail in
The shoulder 4 of the shingle exhibits an outer edge 10 which is sharp as a knife and which is shown in
The in principle known rafters are designated with the reference numeral 9. A cross-section through the representation of
The shingle according to the present invention can be subdivided in half or also in three parts in particular for forming the edge zones of roofs, wherein the half elements or third elements are part of the general present invention principle.
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of roofing system configurations and shingle laying procedures differing from the types described above.
While the invention has been illustrated and described as embodied in the context of a shingle, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.
