The present invention relates to a non-rotating decorative cap which can be fixed to a rotating body, and in particular, the present invention relates to a non-rotating decorative cap which can be fixed at the center of a vertically rotating member such as a vehicle's wheel; thereby showing a non-rotating state of a pattern, emblem or advertisement irrespective to the rotation of a rotating member.
Non-Rotating decorative caps are widely known as vehicles' accessories, which are used to display logos, emblems, or advertisements upon; wherein such caps use adhesives in order to be installed, and use transparent protective covers on the displayed item; wherein the transparent cover causes dust to be accumulated between the transparent cover and the displayed item; and wherein such caps vibrate at certain speeds causing the displayed item to vibrate, and thus become unreadable.
To overcome the rotation problem of regular decorative wheel caps which causes the logo, emblem, advertising or pattern of the caps to be unreadable during the motion of the vehicle, a new non-rotating wheel cap must be put in place with an engineered shape that prevents the caps from vibrating. The new cap must be light in weight, easier to install and more stable than those in the prior art, and does not use any protective covers to prevent the accumulation of dust in order for the logo to be readable all the time.
Through the movement of a vehicle and during the rotation of the vehicle wheels, any decoration; whether it was a logo, an advertisement or an emblem imprinted on a regular wheel cap becomes impossible to be seen and identified clearly, and after the vehicle stops in a static position, the decoration rarely remains in its upright position and usually stops in a tilted manner, therefore, the main purpose of such cap is to exhibit certain decorative shapes clearly.
Having discussed the main flaw in a regular wheel cap, the need for a non-rotating wheel cap that overcomes this flaw becomes apparent, but due to the limitations of acceptable prices paid for wheel caps and due to constructive and design-related issues, the mechanism that keeps the decoration in its upright vertical position in such caps must be cost effective, simple in design, small in size, light in weight and easy to clean, therefore it is a main objective of the present invention to provide a non-rotating wheel cap that is distinguished by these advantageous features.
To achieve the objective of the present invention, all the components of the non-rotating wheel cap disclosed in this invention are press-fitted to each other in order to avoid the usage of bolts and nuts; which would increase the weight of such cap, and accordingly increases the force needed to maintain such cap in its upright position. Such cap is installed in its position at the center of a wheel rim using fixtures, thus, it is easy for the user himself to install and uninstall such cap, whenever he pleases. Narrow spaces are avoided in the cap of the present invention, since these spaces increase the difficulty of cleaning such cap. The decorations displayed on such cap are at the most apparent component on the outer side of such cap, with no transparent surfaces covering the decoration, since these surfaces are known for accumulating mist.
There is provided a non-rotating wheel cap device for displaying decorations at the center of a vehicle's wheel rim, the device comprising:
Preferably, the cylindrical body 1 and the cylindrical housing 9 are made out of plastic, while the crescent-shaped body 4 and said metal sheet 37 are made out of metal. Preferably, the cylindrical holes 7 are three holes. Preferably, the cylindrical housing 9 is adapted to cover the opening 18 of the cylindrical body 1. Preferably, the roller bearing 6 and the crescent-shaped object 4 are adapted to be enclosed inside the inner body space between the opening 1 and the bottom wall 19.
Further features and advantages of the present invention will become apparent from the following detailed description, taken in combination with the appended drawings, in which:
Preferably, the bottom wall 19 is inclined upwards toward the pin 3.
Preferably, said pin 3 comprises a curved base 300, a cervix 301 and a head 302 with the head and cervix forming a mushroom-shape such that the radius of the cervix 301 at the point of connection to the head 302 is greater than the radius of the remaining portions of the cervix 301. Said head 302 and part of the cervix 301 are divided into three symmetrical parts 3a, 3b, 3c.
Preferably, said cylindrical body has a plurality of holes 38 distributed radially at the distance between the upper and lower body edges 16,17.
The inclination of said bottom base 19, the curvature of the pin base 300, and the holes 38 allows for better centrifugation force to clean the device of the present invention.
Preferably, each of the supporting members 2 of the cylindrical body 1 has supporting member 200 connected to said lower lip portion 22.
Preferably, desired decorations are printed on the concaved circular metal sheet 37.
The cylindrical body 1 and the cylindrical housing 9 are made out of plastic, and the crescent-shaped object 4 is made out of metal. Preferably, the cylindrical holes 7 are three holes. Preferably, the cylindrical housing 9 is adapted to cover the opening 18 of the cylindrical body 1. Preferably, the roller bearing 6 and the crescent-shaped object 4 are adapted to be enclosed inside the inner body space between the opening 1 and the bottom wall 19.
From the discussed features of the preferred embodiment of the present invention, it is clearly noticed that the cylindrical body 1 can be manufactured based on the central space of a wheel rim, thus, and due to the compact design of the non-rotating wheel cap disclosed in present invention and since these designs enfold the mechanisms needed to keep the upright position of the cap inside the inner space of the cylindrical body 1, the cap can be simply inserted in the inner space of any wheel rim with no need to any modifications, in a manner similar to any regular wheel cap.
Excluding the roller bearing 6, the crescent shaped object 4 and concaved circular metal sheet 37; which are made out of metal, all the components of the cap are made of plastic, in order to reduce weight; wherein such reduction in weight enables the single roller bearing 6 to efficiently hold the cap in its upright position.
The non-rotating wheel cap of the present invention has also been tested at a machine that rotates the wheel of a vehicle in order to simulate the actual motion of vehicles. Going at a simulated speed that exceeds 400 km/hr, the non-rotating wheel cap disclosed in the present invention kept at an upright position during the whole period of the test.
Although the above description of the present invention has disclosed the features of the invention as applied to the preferred embodiment; additions, omissions and modifications applied to the details of the embodiment illustrated may be made by those skilled in the art without departing from the essential characteristic of the present invention.
