Abstract
Description
- The present invention refers to an element for fastening devices, in particular for sports footwear such as, for example, skiing or snowboarding shoes or boots, skates, climbing boots, cycling shoes, and to a process for manufacturing such element.
- Lever-type fastening devices are widely used in footwear, particularly in the sport field. Strength and lightness are thus essential requirements to provide a functional product, which must obviously be combined with an attractive look and, not less important, a favourable final cost of the finished item.
- The price, in addition to the quality of the materials used, also depends on the type of processes that are carried out in making the various elements and on the reproducibility of the same.
- At present, the fastening devices most commonly used include a jointed buckle lever on a base fastened to one of the edges of the footwear to be fastened. On the lever arm is pivoted a rod that is in turn connected to engaging means, such as for example a hook, suitable to engage corresponding engaging means integral with the other edge of the footwear, generally consisting of a rack means (an example of such fastening means is shown in
figure 8 ). - All the components described above are made separately and assembled later through fastening or mechanically coupling means. In particular, the lever arm and the hook are obtained from an extruded element suitably subjected to milling to produce internal undercuts, to form holes for holding articulation means and for aesthetic shaping.
- Although the lever arm and hook have somewhat similar shapes, they are made from different profiles, generally extruded in a direction transversal to their longitudinal extension and subsequently trimmed by milling.
- However, by extruding the profiles in a transversal direction, the fibres in the material of the starting element are orientated in a direction perpendicular to that of the loads to which the element is subjected when in actual use, which is definitely a disadvantage in terms of strength and durability of the fastening device.
- Moreover, the precision milling of a mechanical piece is a very delicate and costly process involving, moreover, a considerable quantity of waste due to the necessity of operating on profiles having a certain thickness: these characteristics determine to a considerable extent the final price of the component.
- The main objective of the present invention is to resolve the drawbacks of the prior art by devising elements of fastening devices, such as for example a lever arm or a hook, obtained from a single profile having a particular geometry and through an extrusion process that makes it possible to impart particular properties of strength and lightness to the same element.
- In the scope of the above objective, an important aim is to devise an element for fastening devices that can be obtained by shearing alone, without requiring costly and delicate milling operations.
- Also with the aim of containing the cost of the pieces, a further objective of the present invention is to devise an element for fastening devices that can be obtained with a minimum production of waste, with resulting savings in terms of material used.
- A further objective of the present invention consists of devising an element for fastening devices achieved with short production times, by increasing the capability of manufacturing the fastening devices.
- An equally important objective is to devise an element for fastening devices that accomplishes the above purpose and objectives at competitive production costs, so that its use is advantageous also from the economic point of view, and that can be obtained with the usual well-known plants, machines and equipment.
- The above-mentioned purpose and objectives, and others that will become more evident later, are achieved with an element for fastening devices, particularly for sports footwear as defined in
claim 1. - Further characteristics and advantages obtainable with an element for fastening devices according to the present invention will be more evident from the following description of a particular, but not exclusive, embodiment shown by way of non-limiting example with reference to the following figures:

figure 8 shows, by way of example, a prior-art fastening device, and -
figure 9 show, by way of example, a fastening device including elements according to the present invention. - As mentioned above, the fastening devices generally used include a lever arm jointed to a base fastened to one of the edges of the footwear to be fastened. On the lever arm is pivoted a rod that is in turn connected to engagement means, such as for example a hook, suitable to engage corresponding engaging means integral with the other edge of the footwear, generally consisting of a rack means (
figure 8 ). - To achieve the basic purpose of the present invention, a particular geometry has been studied that makes it possible to obtain elements for fastening devices such as a lever arm and/or a hook engaging the rack made from a single profile.
- With reference to
figure 1 ,reference number 1 generally indicates a profile having characteristics suitable to achieve the above specified objectives; in particular, saidprofile 1 is extruded in a direction parallel to the longitudinal extension of the element that is to be produced and has a transversal cross section that resembles the Greek letter "π". - Said profile includes a
plate 1A having a longitudinal extension L greater than the transversal extension T, from which protrude, perpendicularly to one of the two faces of theplate 1A, a first and a secondlongitudinal ribs plate 1A, along the entire longitudinal extension L of the same plate. - Said
plate 1A may have a substantially rectangular cross section, as shown infigure 2A , or, as an alternative, it may be suitably shaped, as shown solely by way of example in figures from 2B to 2F. - From a profile having a geometry as described above, it is possible to obtain an
engaging hook 10 and/or alever arm 20 suitable to be used in a fastening device for sports footwear. - To manufacture an
engaging hook 10 it is sufficient to create a through opening 11 on a longitudinal portion of theplate 1A, in particular in the space included between said first and saidsecond rib hook 10 to interface with corresponding engaging means provided on the rack, and a plurality ofholes 13, suitably arranged on said first andsecond rib - Similarly, to obtain instead a
lever arm 20 it is sufficient to create a through opening 21 on a longitudinal portion of theplate 1A, in the space included between said first and saidsecond rib holes 23, suitably arranged on said first andsecond rib - In addition, to give elements of
fastening devices plate 1A and on theribs plate 1A can be bent. - A particularly advantageous procedure to obtain an element for fastening devices from a
profile 1 having the geometry as described above includes a succession of cold-sheared slots as will be illustrated in greater detail later. In particular, said procedure is known in the metal plate processing field as transfer-die process. -
Figures 3A, 3B and4 illustrate, in different views, the subsequent processing phases of theextruded profile 1 according to the geometry described above, to obtain anengaging hook 10; likewise, infigures 5A, 5B and6 are shown, in different views, the subsequent steps of processing theextruded profile 1 according to the geometry described above, to obtain alever arm 20. - In general, the
profile 1 is inserted into the front of the relative machine comprising the transfer dies, where it is subjected in a continuous process to a plurality of subsequent machining operations during its feeding movement, which takes place preferably in a horizontal direction indicated in the figures by the arrow D. - Initially, only a head portion of said
profile 1 is inserted into the machine, and in particular a portion having an extension substantially equal to the width of a first element for the fastening devices to be manufactured. - Said portion reaches a first work station where it undergoes a first processing step consisting of shearing by means of a relative die, preferably in a direction perpendicular to the plane defined by the
rectangular portion 1A, in the direction indicated by the arrow A. - This step creates a central through opening 11 suitable to create the space necessary for the
hook 10, in actual working conditions, to interface with the rack; in the case of thelever arm 20, the first shearing step creates a through opening 21 suitable to provide the central sheared opening for receiving the rod. - If necessary, during said first processing step, an
aesthetic edge contour rectangular portion 1A of theprofile 1, the shape of which can be determined at will through a suitable shaping of the die, providing it is included within the side edges of therectangular portion 1A projecting from theunderlying ribs profile 1. - Advantageously, if required, the particular geometry of the
profile 1 makes it possible to create said through opening 11, 21 substantially flush with theribs ribs figure 7 . - Once said first vertical shearing phase is completed, the portion that has undergone such operation is moved forward by translating the
profile 1 horizontally in the direction indicated by the arrow D until it reaches a second work station; at the same time, due to the horizontal translation of theprofile 1, a second portion of theprofile 1 immediately adjacent to the first portion, and having substantially the same longitudinal extension, is inserted into the first shearing station, where it undergoes the first processing step described above. - Said second processing step consists of a shearing operation in a direction perpendicular to the direction A of the first shearing step and transversal to the extension L of the
profile 1. The direction of said second shearing is shown in the figures with the arrow B. - Through said second step, on both of said first and
second rib profile 1 is created a plurality ofholes side shaping feature - Subsequently, as with the previous phase, the portion that has undergone said second shearing is made to translate horizontally in the direction indicated by the arrow D until it reaches a subsequent processing station.
- Consequently, said translation also involves the translation of the second portion, which has just undergone the first shearing step, to the second processing station, as well as the insertion into the machine of a further portion of the still
intact profile 1, which will be subjected to the first processing step. - Thus, the portion that was first inserted now reaches the third processing station, where any required bending of the portion according to known procedures and its final shearing with respect to the previous portion is carried out, in a direction parallel to the transversal extension T of the
profile 1, to obtain a first finished piece forming the desired component. - Clearly, the final shearing step and the bending step can be carried out at the same time or in sequence, in the order desired; the bending operation itself is optional and thus it can be omitted.
- The subsequent portions will afterward be subjected to the bending phase and/or final shearing to form the component elements as the
profile 1 is fed into the machine and the unfinished portions translate to the following processing station. - The succession of the steps as described above is the one that is most advantageous, but, obviously, the sequence can be modified without thereby departing from the scope of the present invention.
- Further, preferably, until the last shearing step is reached, none of the component elements are yet formed, and they remain still joined to the previous unfinished piece and/or to the following one. However, it is pointed out that the shearing step with which an unfinished portion is separated from the adjacent unfinished portions could take place in any other phase.
- In other words, in summary, a preferential process for manufacturing an
element profile 1 having the geometry as specified above includes, even in a different sequence, the steps of: - a) shearing a first longitudinal portion of said
profile 1 in a first direction A perpendicular to saidplate 1A to form on saidplate 1A a substantiallycentral opening second rib - b) shearing said first portion of said
profile 1 in a second direction B substantially perpendicular to the direction of said first shearing A and transversal to the extension L of theprofile 1, to form a plurality of throughholes second rib element - c) subjecting said first portion of said
profile 1 to a further shearing in said first direction A suitable to separate transversally said longitudinal portion from the remaining part of theprofile 1 to form saidelement - In addition, preferably during step a) a shearing step can be carried out on the side edges of said
plate 1A to obtain afirst edge contour second rib second edge contour - Finally, the above process can also include a further step d) in which said
element -
Figure 9 illustrates, by way of example, a fastening device comprising elements offastening devices profile 1 having the geometry previously described and using the process disclosed above. - From what is disclosed above, it is thus evident that the present invention achieves the initially foreseen objectives and advantages: in effect, a particular geometry was thought out to apply to an extruded profile so as to be able to obtain, through a particular extrusion process, elements of fastening devices with different functions having the necessary strength and lightness; in particular, the elements of fastening devices that can be produced from the same profile geometry are a lever arm and an engaging hook.
- Advantageously, said elements of fastening devices, even if obtained from an extruded profile made from a very strong material such as Ergal®, can be manufactured without the use of costly and delicate milling operations; in fact, the thicknesses and dimensions of each portion of the starting profile have been suitably calibrated so as to make it possible to obtain said elements by shearing alone with a transfer die procedure, a process that is considerably faster than milling and has a moderate cost.
- For the reason disclosed above, the trimming waste produced in the process will also be rather limited, thus making it possible to optimize the resources used, with consequent savings in terms of costs.
- In addition, advantageously, the times for the production of elements of fastening devices from a profile according to the present invention are rather short, with an advantageous increase in their producibility.
- It can be seen, moreover, that by extruding the profile in a direction that is not transversal but parallel to the longitudinal extension of the same profile, the fibres of the material are aligned in the direction of the tensile stresses to which the element is subjected during its use, thus imparting greater strength and durability to the fastening device.
- Naturally, the present invention is open to numerous applications, modifications or variants without thereby departing from the scope of patent protection, as defined by the enclosed claims.
- In addition, the materials and the equipment used for carrying out the present invention, as well as the shapes and dimensions of the individual components, may be the most suitable to the specific requirements.
