The present invention relates to a cover for vehicle tires which comprises means for the fixing thereof to the tire of the vehicle.
The use of covers on the tires of vehicles is common for personalizing the appearance thereof. Normally these covers are made of plastic material and are fixed to the rim of the tire which is made of metal.
The covers must be fixed to the rim of the vehicle in a secure manner which prevents the covers becoming detached from the tire over a long period of time, taking into account the forces to which they are subjected due to the rotational velocity of the tire, force of the wind and vibrations.
At present, different types of fixing means of these covers to the rims of the vehicle are known.
A first type of cover is joined to the tires by means of screws which must be screwed from the interior of the tire. This type of fixing means has the advantage of being very secure since the joining between the cover and the tire is very durable. However, this type of fixing means has the drawback of being awkward to place since they require screwing from the interior part of the tire. In practice, this means that the end user will change said covers with difficulty since it requires removing the tire. Consequently, this fixing method makes the personalization of the tire difficult after purchasing the vehicle by means of replacing the plastic covers by the end client or in the car dealership.
The fixing method of the plastic covers to the rim by means of screws from the interior of the rim means that the plastic covers are mounted by the provider of the rim and not on the assembly line of the manufacturer of the vehicle. The manufacturer of the vehicle is in favor of the frontal mounting of the plastic covers on the rim on their assembly line. The fixing system of the plastic covers by means of screws from the interior of the rim forces the manufacturer of the vehicle to provide a larger space in their manufacturing plant for storing rims with different plastic cover models. This situation is especially critical when a high number of plastic cover models (different colors) can be mounted on the same rim model. Consequently, the fixing system of the covers by means of screws from the interior of the rim makes the flexibility desired by the manufacturer of the vehicle when personalizing the tire of the vehicle by means of mounting different plastic covers on the rim very difficult.
A second type of cover is joined to the tires by means of adhesive, for example a double-sided adhesive tape. This fixing system has been shown not to be suitable in practice since the fixing thereof is permanent and does not allow the cover to be removed and replaced with another.
Therefore, the need for a cover for the use thereof on a tire of a vehicle is evident which can be easily replaced when desired, even by the end user at any time they desire.
Using the cover for tires of the present invention, the cited drawbacks are resolved, presenting other advantages which are described below.
The cover for tires of the present invention comprises fixing means which allow said cover to be fixed to a rim of a tire and is characterized in that said fixing means comprise a plurality of protrusions, each one of which is associated with a fixing element.
Advantageously, each fixing element is housed in the interior of one of said protrusions and each fixing element preferably comprises tabs which are housed, in the position of use, in the interior of holes complementary to the protrusions.
Furthermore, each fixing element preferably comprises an exterior projection which, in the position of use thereof, abuts against the interior wall of said protrusions and each protrusion comprises a beveled exterior flange which defines one or two inclined planes which allow the cover to be fixed on the tire or which is fixed on and removed from the tire.
According to a preferred embodiment of the present invention, each fixing element defines a substantially cylindrical shape with lateral openings and each protrusion also defines a substantially cylindrical shape with lateral openings.
Advantageously, the fixing elements are made of metal and the protrusions are made of plastic material.
Using the cover for tires of the present invention, the following advantages, amongst others, are achieved:
In order to better understand what has been stated, drawings are enclosed, in which, schematically and only by way of non-limiting example, a practical embodiment is depicted.
A part of a rim 2 of a tire of an automobile has been depicted in
The cover 1 comprises fixing means which allow it to be fixed to the rim by the front part thereof under pressure such that it can be easily placed and removed as and when desired, even by the end user.
Said fixing means comprise a plurality of protrusions 3 distributed conveniently on the rear part of the cover 1, that is to say, on the part which is in contact with the rim 2 such that the cover 1 is correctly fixed to the rim 2.
Said fixing means also comprise fixing elements 4, each one of which is housed in the interior of a protrusion 3, as is described below in greater detail.
The structure of the protrusions 3 can be observed in
Each protrusion 3 comprises a flange 8 on the end thereof furthest from the joining with the rest of the cover 1. This flange 8 is beveled, defining two inclined planes, as can be observed in
The geometry of the flange 8 can be modified so that the removal of the plastic cover from the frontal part of the tire is prevented, if the vehicle manufacturer so desires. This option may be appealing for preventing the theft of the plastic covers from the frontal part of the tire. The removal of the plastic covers must, in this case, be carried out from the interior of the tire. In this case, the beveling of the flange 8 would not define a triangular transversal section, but rather would only define an inclined plane which would allow coupling the cover 1 under pressure.
In
Each fixing element 4 comprises tabs 5 which are housed in holes 7 of said protrusion 3, as can be observed in
It must be indicated that the fixing element 4 can be housed in the interior of the protrusions 3 by means of different methods, such as for example insertion during the molding, insertion under pressure, insertion using ultrasound, insertion with heat, etc.
The fixing elements 4 are made of metal and the principal function thereof is to maintain the tension for retaining or fixing the cover 1 on the rim 2. Without these fixing elements 4, the plastic protrusions 3 alone could not maintain the tension and the cover 1 could separate from the rim 2 after a certain period of time.
As has been previously indicated, the mounting and removal of the cover 1 from the rim is very simple and can be carried out by the end user themselves as and when desired.
In order to place the cover 1 of the present invention in a simple manner, the protrusions 3 must be placed in front of the corresponding housings of the rim 2 and sufficient pressure be applied so that the end of the protrusion 3 provided with the flange 8 is elastically deformed, allowing the anchoring or fixing of the cover 1 owing to the inclined surface of said end.
According to the embodiment depicted, in order to remove the cover 1 from the tire 2, the cover simply has to be stretched with respect to the rim 2, applying the force required for the end of the protrusion 3 provided with the flange 8 to be elastically deformed, allowing the cover 1 to be removed owing to the inclined surface of said end.
However, as previously mentioned, the geometry of the flange 8 can be modified so that the removal of the plastic cover from the frontal part of the tire is prevented if the vehicle manufacturer so desires. This option is appealing for preventing the theft of the plastic covers from the frontal part of the tire. The removal of the plastic covers must, in this case, be carried out from the interior of the tire.
In spite of reference having been made to a specific embodiment of the invention, it is evident for a person skilled in the art that the cover for tires described is capable of undergoing numerous variations and modifications and that all the details mentioned can be substituted for others that are technically equivalent without departing from the scope of protection defined by the attached claims.
