DETAILED DESCRIPTION OF THE INVENTION

(11) As required, detailed embodiments of the present invention are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of an invention that may be embodied in various and alternative forms. Therefore, specific functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for the claims and/or as a representative basis for teaching one skilled in the art to variously employ the present invention.

(12) The following description is presented to enable any person skilled in the art to make and use the invention, and is provided in the context of particular applications of the invention and their requirements.

(13) The invention described herein thus comprises a novel, snow chain device for providing good traction to a vehicle tire. Said device is capable of being removably mounted on the tire with reduced effort and in multiple configurations as well as in a stackable format. The device comprising:

(14) (a) a plurality of link members,

(15) (b) a plurality of base members,

(16) (c) a plurality of adhesive strips, corresponding in equal number to said plurality of base members.

(17) Each link member further includes a chain member and an arch member. Each arch member has a top surface, a bottom surface and a plurality of projections at predefined locations on its bottom surface. The chain member is affixed on the top surface of the arch member. The arch member is shaped to conform substantially to the curvature of the tire. Each base member has a top surface including recessed portions and a bottom surface. The base member is capable of being affixed to an external tire surface, and has a plurality of holes at predefined locations. Each adhesive strip includes a peelable, adhesive front surface, that faces the bottom surface of the base member, and a peelable, adhesive back surface, that faces the external tire surface. The base members are affixed on the external tire surface by means of the adhesive strips. The link members are positioned vertically above the base members, such that the projections of the link members engage with the corresponding holes of the base members. The link members are removably secured with the base members and form a predefined configuration on the external surface of the tire.

(18) FIG. 1 depicts a perspective view of a snow chain device 10 in accordance with the present invention, mounted on a tire 60. Link members 20, base members 30 and adhesive strips 40 are also shown. In this view, only a part of the link members have been positioned on base members.

(19) FIG. 2 depicts a front view of a snow chain device 10 in accordance with the present invention, mounted on a tire 60. Link members 20, base members 30 and adhesive strips 40 are also shown.

(20) FIG. 3 depicts a side view of a snow chain device 10 in accordance with the present invention, mounted on a tire 60.

(21) FIGS. 4a, 4b and 4c depict three alternate views of a link member 20. 21 is a chain affixed to an arch member 22. The arch member 22 is shaped to conform substantially to the curvature of the tire and has projections 23 on its bottom surface.

(22) FIG. 5a represents an illustrative view depicting base members 30 having a recessed top surface 32 and a plurality of holes 34, affixed on adhesive strip 40, which is affixed on the tire 60, in a given configuration of the base members.

(23) FIG. 5b is an illustrative diagram depicting a base member 30 having a recessed top surface 32 and a plurality of holes 34, affixed on adhesive strip 40, which is affixed on the tire 60, in an alternate configuration of the base members.

(24) FIG. 6 is an illustrative diagram depicting a base member 30 having a recessed top surface 32 and a plurality of holes 34, positioned above an adhesive strip 40.

(25) FIG. 7 is an illustrative diagram depicting a base member 30 and an adhesive strip 40 prior to being affixed on an external surface of a tire 60.

(26) FIGS. 8a, 8b and 8c are illustrative diagrams depicting a base member 30 in conjunction with a peelable top surface 41 of an adhesive strip 40.

(27) FIGS. 9a, 9b and 9c are illustrative diagrams depicting a base member 30 in conjunction with a peelable back surface 42 of an adhesive strip 40.

(28) In an embodiment of the invention, it is possible to cover an entire external surface of a tire using the present snow chain device.

(29) In an alternate embodiment of the invention, the present snow chain device can be used to partly cover a specific surface area of a tire.

(30) In one embodiment of the invention, it possible to vertically stack multiple layers of base members and chain members to create a device with greater thickness for higher traction. In such an embodiment, additional layers of adhesive strips are required between the layer of base members and the layer of link members.

(31) In one embodiment of the invention, it is possible to arrange the base members and link members in any number of symmetric or unsymmetrical pattern as desired depending on the level of traction required. The link members can be in any possible size and design pattern.

(32) The present invention is easy to mount or dismount since the link members can be removably secured to the base members. The base members are fastened on the external surface of a tire using adhesive layer having a peelable top surface and a peelable bottom surface. The adhesive layers may be made of 3M Command double side strip adhesive tape, for example. The adhesive strips are disposable and need to be disposed off after each use. The base members and the link members can be reused.

(33) Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.

(34) Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present invention. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
