20210053641
The present invention in general relates to the field of accessories for motor vehicles, and more specifically it relates to a legs apron for a motor vehicle.
In the field of motor vehicles, such as motor scooters by way of non-limiting example, it is known to use legs aprons serving the function of protecting the legs of the driver against bad weather, especially during the winter. In particular, legs aprons of the divisible type are known, i.e. legs aprons which comprise a first and second part of apron which may be removably coupled together. Examples of divisible legs aprons are described in Patent Application EP2998207 to Bagster and in Patent Application FR2826627 to Motopolis.
A drawback of the above-mentioned divisible legs aprons of the known art is associated with the fact that a water leak may occur in such aprons along the junction line between the two parts of the apron, particularly when the motor vehicle is moving and the water is pushed according to a direction which substantially is parallel to the plane of the apron. Moreover, leaks may occur in such aprons along the junction line between the two parts of the apron when the legs apron collects water during the stops of the motor vehicle (for example, when the motor vehicle is stopped at the traffic light or parked outdoors, etc.).
It is an object of the present description to make available a legs apron for a motor vehicle which allows the above-mentioned drawbacks with reference to the known art to be resolved or at least partly obviated.
These and other objects are achieved by means of a legs apron for a motor vehicle as defined in claim 1 in the most general embodiment thereof, and in the claims dependent thereon in certain particular embodiments thereof.
In particular, the aforesaid object is achieved by means of a legs apron for a motor vehicle, comprising:
The leaking of water may indeed be reduced or avoided along the junction line between the two parts of the legs apron due to the fact of making waterproof the junction line between the first and second part of apron.
In particular, said at least one waterproofing element may comprise a first longitudinal flap which extends from one of the first and second part of apron and which is adapted to overlap the junction line.
In other words, the first longitudinal flap may extend from the first part of apron towards the second part of apron, or vice versa it may extend from the second part of apron towards the first part of apron. In the first version, the first longitudinal flap is fastened to the first part of apron. The legs apron comprises at least one fastening element arranged for stably and removably fastening, when said first flap overlaps the junction line, said first flap to the other part of apron selected from the first and second part of apron from which the first longitudinal flap does not extend. In other words, if said first flap is fastened to the first part of apron, said first flap surmounts the junction line and is removably fastened at the second part of apron by means of the fastening element. If, contrarily, said first flap is fastened to the second part of apron, said first flap surmounts the junction line and is removably fastened at the first part of apron by means of the fastening element.
Moreover, said at least one waterproofing element may comprise a second longitudinal flap which extends from the aforesaid other part of apron. According to one embodiment in particular, a first longitudinal flap is provided connected to the second part of apron and a second longitudinal flap connected to the first part of apron. In particular, said second flap is configured so as to overlap the junction line and at least partly the first longitudinal flap.
According to one embodiment, said first and second flaps each comprise a first face adapted to face the junction line and an opposite second face. In particular, the second flap is configured so as to overlap the first longitudinal flap so that at least a portion of the first face of the second longitudinal flap may overlap at least a portion of the first face of the first longitudinal flap.
The overlapping between the first and the second flap occurs in the area of the second part of apron. The first flap in particular is positioned so as to surmount the junction line, thus being positioned in the area of the second part of apron. At this point, the contact occurs between the first flap and the second flap, which overlap so as to close and isolate the junction line. According to one embodiment, said first and second flaps may be folded together, in particular according to a longitudinal line parallel to the junction line, so as to achieve a labyrinth seal therebetween once the second longitudinal flap overlaps the first longitudinal flap.
Thereby, a particularly effective seal may be obtained which with respect to the solutions of the known art, allows the leaking of water to be avoided or significantly limited along the junction line between the two parts of the apron, both when the vehicle is moving and the water is pushed according to a direction substantially parallel to the plane of the apron, and when the apron collects water during the stops of the motor vehicle.
According to an advantageous embodiment, said at least one waterproofing element comprises a longitudinal extension which protrudes from said first face of the first longitudinal flap and which is joined to the first face of the first longitudinal flap so as to define a fold line.
In other words, the longitudinal extension in turn is a portion of flap, or a duplication, of the first flap, which partly is connected to the first face of the first flap in a connection portion and extends overhangingly therefrom, thus forming a fold line. The latter substantially is obtained downstream of the connection portion. In particular, said second flap is adapted to at least partly overlap said longitudinal extension so as to be folded together with the longitudinal extension about the fold line.
Conveniently, the fact of providing the aforesaid longitudinal extension which protrudes from the first face of the first longitudinal flap allows the overlapping of the first and the second longitudinal flap to be facilitated and accordingly, the labyrinth seal to be made in a particularly easy manner.
The longitudinal extension may comprise at least one stiffening element, or may be made of substantially rigid material. This advantageously allows both the labyrinth seal to be made in an even easier manner and increased rigidity to be given to the labyrinth seal itself, thereby making it increasingly effective.
According to one embodiment, the first longitudinal flap comprises a free longitudinal edge and a longitudinal portion extending between the aforesaid fold line and the free longitudinal edge. Said at least one fastening element may comprise complementary fastening elements including a first and a second fastening element. The first fastening element is arranged on the first face of said first flap at said longitudinal portion. The second fastening element is adapted to be coupled with the first fastening element and is arranged on the second face of the second longitudinal flap or on the part of apron from which said second flap extends.
According to one embodiment, the first and second fastening elements are longitudinal fastening elements which extend throughout the entire or substantially the entire length of said first and second flaps. The fact of providing such longitudinal fastening elements advantageously allows the fastening elements themselves to be used to create a barrier for the water which tends to seep through the fastening elements.
According to one embodiment, said first and second fastening elements comprise a first and a second strip of Velcro, respectively. The first and second Velcro strips preferably are fastened to the first and second part of apron, respectively, by means of high frequency welding. Thereby, the waterproofing elements are able to ensure a more effective sealing because the fastening of the Velcro strips by means of high frequency welding prevents the passage of the water between each Velcro strip and the longitudinal flap to which such a strip is fastened, contrarily to the case in which for example, the Velcro strips are sewn to the respective longitudinal flaps.
Alternatively to Velcro strips, said first and second fastening element may comprise a first and a second magnetic strip, respectively.
According to one embodiment, said first and second flaps are connected to the respective part of apron by means of high frequency welding. Thereby, the waterproofing elements are able to ensure a more effective sealing because the connection by means of high frequency welding prevents the passage of the water between each of said flaps and the respective part of apron, contrarily to the case in which for example, said first and second flaps are sewn to the respective parts of apron.
At least one between the first and second flaps preferably is a waterproof flap.
According to one embodiment, said at least one waterproofing element comprises said coupling system. In particular, said coupling system may comprise a waterproof zipper.
According to one embodiment, the legs apron may comprise an anti flap system.
According to one embodiment, the legs apron may comprise an internal heating system.

With reference initially to
With reference to
Apron 10 comprises at least one waterproofing element 40, 50, 60, 80 arranged to waterproof the junction line L1. The at least one waterproofing element 40, 50, 60, 80 comprises a first longitudinal flap 50 which extends from the first part 20 of apron and which is adapted to overlap the junction line L1. In the example shown in the accompanying drawings in particular, the first flap 50 belongs to the second part 30 of apron. The legs apron 10 further comprises at least one fastening element 70A, 70B arranged to stably and removably fasten, when the first flap 50 overlaps the junction line L1, the first flap 50 to the first part 20 of apron, i.e. to the part of apron 10 from which the first flap 50 does not extend. According to one embodiment, the at least one waterproofing element 40, 50, 60, 80 comprises a second longitudinal flap 60 which extends from the first part 20 of apron. In particular, the second flap 60 belongs to the first part 20 of apron. The second flap 60 is configured so as to overlap the junction line L1 and at least partly the first longitudinal flap 50. It is worth noting that according to an alternative embodiment, the first flap 50 and the second flap 60 may be inverted or arranged on a same side of the apron. In other words, the first flap 50 could extend from the first part 20 of apron rather than from the second part 30 of apron, and the second flap 60 could extend from the second part 30 of apron rather than from the first part 20 of apron. According to one embodiment, the first and second flaps 50, 60 are connected to the respective part of apron 20, 30 by means of high frequency welding.
The first and second flaps 50, 60 are shaped to couple to each other and to be folded along a substantially longitudinal fold line P1, i.e. parallel to the junction line L1, so as to achieve a labyrinth seal coupling. The coupling between the first and second flap and the successive fold is achieved up to obtaining a flat arrangement of the first longitudinal flap (50) and of the second longitudinal flap (60) coupled to each other.
The first and second flaps 50, 60 each comprise a first face 51, 61 adapted to face the junction line L1 and an opposite second face 52, 62. According to one embodiment, the second flap 60 is configured so as to overlap the first longitudinal flap 50 so that at least a portion of the first face 61 of the second longitudinal flap 60 may overlap at least a portion of the first face 51 of the first longitudinal flap 50. According to one embodiment, at least one between the first 50 and the second flap 60 is a waterproof or impermeable flap. In the example shown in the accompanying drawings, both the first flap 50 and the second flap 60 are waterproof flaps.
According to one embodiment, the first and the second flaps 50, 60 may be folded together so as to achieve a labyrinth seal (
According to one embodiment, the at least one waterproofing element 40, 50, 60, 80 comprises a longitudinal extension 80 which protrudes from the first face 51 of the first longitudinal flap 50 and which is joined to the first face 51 of the first longitudinal flap 50 so as to define a fold line P1. In particular, the second flap 60 is adapted to at least partly overlap the longitudinal extension 80 so as to be folded together with the longitudinal extension 80 about the fold line P1.
According to an advantageous embodiment, the longitudinal extension 80 comprises at least one stiffening element. Such a stiffening element may be, by way of non-limiting example, both a rigid element with respect to the fabric of the longitudinal extension 80 which is fastened to the longitudinal extension 80, for example a stiffening element made by means of a rigid longitudinal band fastened to the longitudinal extension 80, and a stiffening element integrated in the longitudinal extension 80, which may be made for example by means of a thickening of the longitudinal extension 80.
According to one embodiment, the first longitudinal flap 50 comprises a free longitudinal edge 53 and a longitudinal portion 55 extending between the fold line P1 and the free longitudinal edge 53. Moreover, the at least one fastening element 70A, 70B comprises complementary fastening elements 70A, 70B. Such complementary fastening elements are depicted in
According to one embodiment, the at least one waterproofing element 40, 50, 60, 80 may comprise a waterproofing element integrated in the coupling system 40 in addition or alternatively to the first and second flap 50, 60. In such a case, the coupling system 40 may comprise for example, a waterproof zipper 40.
According to one embodiment, apron 10 may comprise an anti flap system 90. The anti flap system 90 preferably comprises a plurality of plate-shaped stiffening portions 90 which overlap and are fastened to the side wings 22A, 22B of apron 10. Although the stiffening portions 90 in the drawing are fastened to the outer side of apron 10, such portions 90 preferably are fastened to the inner side of apron 10. The portions 90 are constructively simpler, efficiency being equal with respect for example to known anti flap systems which use bars or similar anti flap elements made for example of polymeric foam or of polystyrene, and moreover have reduced thickness. Thereby, the portions 90 are not an impediment for the driver, especially when the driver is to put his/her foot on the ground during stops. The portions 90 are obtained as thickening of the apron by means of portions which are for example, glued. In the example disclosed, the anti flap system 90 comprises, by way of non-limiting example, four plate-shaped stiffening portions 90, two of which are fastened to wing 22A and two of which are fastened to wing 22B. The plate-shaped stiffening portions 90 create an increased thickness of apron 10 and therefore a stiffening effect which reduces or eliminates the flapping of the wings 22A, 22B. According to a preferred embodiment, the plate-shaped stiffening portions 90 are made by means of high density neoprene plates.
According to one embodiment, apron 10 comprises a heating system (not shown in the drawings). Such a heating system preferably is an internal heating system, i.e. a heating system arranged on or on the inner side of the apron (in other words, on the face of apron 10 intended to face, in use, the legs of driver C1) or inserted in apron 10 itself. In particular, the heating system may comprise heating systems in themselves known, such as for example a synthetic fur applied on the inner side of apron 10, preferably at at least the middle portion 23 of apron 10, or an electrical resistance inserted in apron 10 and connectable to the electric system of motorcycle 1 for example, by means of a USB port.
Having described the structure of apron 10, now an example method for achieving the sealing of the junction line L1 of apron 10 is described by way of non-limiting example with reference to the embodiment shown in the accompanying drawings.
With reference to
In an advantageous embodiment, the legs apron further comprises an anti flap system which comprises at least one stiffening element coupled to the legs apron.
Additionally, the legs apron comprises an internal heating system adapted to heat the space delimited by the legs apron in which the legs of the user are placed.
