CONTAINER WITH A SUCTION-CUP ATTACHMENT PARTICULARLY FOR MOTORCYCLES

Abstract: According to the invention a container (1, 11) is obtained, particularly for motorcycles, consisting of a box (4,13) provided with a lid and at least with a bottom suited for the transportation of goods, wherein the stable connection between the container and the motorcycle body is obtained by means of one or more suction cups (3) attached to the bottom (2,12) of the container and adhering to the motorcycle body. According to a form a of execution of the invention the container (1) has a double bottom; on the outer one (2), one or more suction cups (3) are attached. According to another form of execution the container (11) has a single bottom (12) wherein more suction cups are connected to tongues (14,15) permanently attached at the bottom (12).

Description: The invention concerns a container with a suction-cup attachment, particularly suited for motorcycles. The need to provide motorcycles with one or more permanently attached carrier devices has been felt since motorcycles have first been manufactured. In the US-A-4 059 207 and also in the DE-C-860 463 motorcycles with carriers are disclosed consisting essentially of flat stands connected with the body of the motorcycle by belts/or elastic bands on which suitcases, boxes or bags of any type could be strapped with belts or elastic bands, too. The US-A-4 325 531 discloses a carrier device consisting of rigid containers made of plastic in the shape of a box or of a suitcase which are also attached to flat stands described before which are usually positioned behind the seat. The evolution in the motorcycle-design which has occurred in the last few years has led to the construction of motorcycles with one-piece seats and has changed the position of the motorcyclist's upper body leaning forward toward the motorcycle, so that the rear-end of his body is set back toward the rear-end of the motorcycle. This fact has led to the consequence of reducing and, in some cases, of completely doing away with the space available for the connection of containers on the motorcycles. Since motorcyclists have felt the need to have available, nonetheless, a container, in many models said container has found its support area on the fuel tank of the motorcycle. Said containers, which usually acquire the shape of a bag or suitcase, are anchored to the motorcycle or to the fuel tank by mans of bands which may be or not be elastic, but which are, however, always adjustable and which are wound around the fuel tank and then anchored to the tube holding the steering shaft of the motorcycle. A further evolution in the design of motorcycles has provided the motorcycle with on outer shell encasing the fuel tank, so that it is extremely difficult, if not impossible, to wound belts or bands around the fuel tank and, therefore, to attach the container to the motorcycle. The purpose of the present invention is that of overcoming the drawbacks due to the difficulty, or to the impossibility, of attaching a container to the fuel tank of a motorcycle or to parts thereof which are encased. Another proposed purpose which the invention intends to fulfil is that of making available a container which can be attached to the body of the motorcycle without any need for making holes in or for providing fixed fastenings on the body or, at any rate, without causing the container to leave visible marks on the varnish of the body. Not the least purpose is that of obtaining a container which is extremely easy to apply on and remove from the body of a motorcycle and also securely attachable to the body, so that it is not possible for the container to come off while the motorcycle is moving. All the mentioned purposes and others are fulfilled with the technical solution which is defined by the features of the characterizing portion of claim 1. According to a form of execution of the invention, the suction cups of the container are attached to a flat board, preferably but not necessarily made of deformable plastic material, so that it can adapt itself to the surface of the fuel tank to which the suction cups adhere; in this case, the board carrying the suction cups is the outer bottom of the container and it is connected removably on one side with the container, by means of hinges, belts or similar means. According to another form of execution of the invention, the container has a single bottom, which may be or not be rigid, at which one or more suction caps may be directly applied and which adhere to the surface of the fuel tank or to a part of the motorcycle body suited to receive the container. In this case is also useful to expect that the suction cups are set on some tongues which are on the bottom, but outside the container, so that the connection and the detachment of the suction cups to the motorcycle body is possible when the container is closed as well. In the executions of the invention in which suction cups are used, the container has some slots of any shape or a plurality of holes where the suction cups are fitted in order to make the placing of the suction cups possible in the most suitable parts of the motorcycle body. Other characteristics and details of the invention will be better described in the above-mentioned forms of execution, which are given by way of example only, but are not meant to limit the scope of the invention and are represented in the enclosed tables of drawing, where: Fig. 1 represents the container according to the invention, provided with a double bottom and with the suction cups on the outer bottom. Fig. 2 shows a variation of the container of Fig. 1, in which the outer bottom has some slots to adjust the distance between the suction cups. Fig. 3 represents a variation of the inventive container in fig. 1, wherein the outer bottom has plurality of holes to adjust the distance between the suction cups. With reference to Fig. 1, it can be observed that the container, indicated as a whole with 1, consists of a box 4 with its bottom 5 and its lid 6 and of a supporting board 2 that is the second bottom of the box made of a composite flexible plastic material, which, in this case, is made of a sheet of plastic material with an underlying layer of synthetic expanded rubber. The suction cups 3 are arranged at the corners of a quadrilateral and they are permanently attached to bottom 2 by known means. The adherence of the suction cups to the body of the motorcycle is obtained by means of an excentric clamping or by screwing in the known ways. In the case of Fig. 1, the box 4 is connected by means of a finge 7 to bottom 2, so that it can easily be latched or partially or totally unlatched from it said bottom. For instance, should the container 1 be fastened on the fuel tank of the motorcycle, it is obvious that, in case of refuelling, it is particularly useful to have the possibility of tilting the box 4 so as to have access to cap of the fuel tank 9 which protrudes from hole 8 made in the bottom 2, in order to avoid having to remove the box 4 from the motorcycle. Fig. 2 shows a variation concerning the bottom 2 of the container which has the possibility of changing the geometrical arrangement of the suction cups 3 within the slits 16 having cross-shopped cuts made in the place of fixed holes receiving the suction cups. This solution is particularly advantageous when the same container 10 is applied on different motorcycle models. It is in fact obvious that the adjustable arrangement of the suction cups 3 within the slits 6 allows the container 10 of Fig. 2 to adapt itself with its bottom to different motorcycle bodies or to different types of motorcycle fuel tanks. Fig. 3 shows another variation concerning bottom 2 connected with tank 9. In said variation bottom 2 has a plurality of holes able to fit the suction cups 3. In this way the suction cups 3 can be placed in teh most advantageous way according to the shape and the dimension of the tank, to which the container 1 must be connected. In fig. 3 the four suction cups 3 are placed on the four corners of bottom 2, but if the tank 9 were shorter e.g. in length, a couple of suction cups could be put closer to the other one. It has then been demonstrated that the container according to the invention in each of its different forms of execution solves all problems connected with the secure attachment between the container and the motorcycle body without any need for said body to be drilled with holes for the passage of belts or similar. It will also be pointed out that the container which is obtained by means of the suction cups prevents all possible deterioration of the body varnish in correspondence with the points of adherence, both thanks to the material used in manufacturing the suction cups, which is notably flexible plastic material and because the suction cups in themselves do not allow friction movements between the suction cup and the element to which the suction cup adheres. As far the reliability of clamping and adherence between the container of the invention and the motorcycle body is concerned, it will be pointed out that tests performed on prototypes employing four suction cups with a holding strength of approx. 20 kg. each have given very good holding results even while the motorcycle was moving under vibrating and bouncing conditions. Moreover the suction cups may be secured to the surface to which they adhere using different known means, such as the toggle clamping method, the screw clamping method, the eccentric clamping method or also the simple method of clamping a single suction cup without any specific pressure means.
