DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(12) The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

(13) Referring to FIGS. 1-4, a vehicle arrangement 7 of the present invention has a Jeep-type sport utility and/or all terrain type vehicle 10 with a partially open top 12 with a transverse window 14. In the embodiment shown, the transverse window 14 provides a windshield header that is adjacent a front row passenger portion of the vehicle. The window 14 has a ferromagnetic frame 16.

(14) Over the rear seat in seating portion 22 of the vehicle is a weatherproof section top 42. A flexible fabric or mesh, preferably air-permeable membrane or cover 24 provides sun shading of a front row driver and side passenger portion of the vehicle.

(15) The cover 24 has a fabric portion 26. Connected with an end of the fabric portion 26 of the cover is a magnetic portion or member 28. (For clarity of illustration in FIG. 1, the section of the flexible cover connected to the magnetic member 28 is not shown). The magnetic member removably connects the fabric portion to the windshield of the vehicle and tensions the fabric portion 26. The magnetic member 28 has a magnet 29 that can be a singular member or can be comprised of multiple discrete magnetic members 30 as shown in FIG. 5. The magnet portion may be fabricated by a metallic material or include the whole or partial use of a magnetic polymer such as PANiCNQ (a combination of emeraldine-based polyaniline (PANi) and tetracyanoquinodimethane (TCNQ)). In the embodiment shown in FIG. 4, magnetic member portion 28 is encapsulated in a polymeric cover 36. The cover 36 can be a singular material or a combination of materials. The encapsulating material of the polymeric cover 36 may be used to join a plurality of magnetic members 30 into a rigid structural member. The encapsulating material 36 of the polymeric cover can also be selected to aid in sealing the interface between the magnetic member and the frame 16 of the window 14. The encapsulation material can also include portions of the afore described magnetic polymers or such magnetic polymers with a more compliant outer polymer cover layer to enhance sealing.

(16) Attached to the frame surrounding the window 14 can be a latch plate 40. The latch plate can be utilized for connecting a permanent or rigid cover over the front portion of the vehicle. The rigid cover may be a removable cover like cover section 42, that can be stored in the rear of the vehicle or may be as shown a pivotal cover 44. The latch plate has a connection portion 46 to connect to the frame directly or indirectly. The latch plate may have a connection portion 48 for connection with a top and rigid cover. To release the cover 24, a vehicle operator can just displace the magnetic member 28 from the window frame. As well known to those skilled in the art, the cover 24 may have openings (not shown) for the connecting hardware of the cover 44 to connect with the latch plate.

(17) As shown in FIG. 10, a magnetic member 28 has an encapsulated tail 51. An inclined portion 53 of the latch plate acts as a stop for the magnetic member 28 in the vehicle's longitudinal direction. In another embodiment (not shown), the inclined portion is formed in almost a 90° angle with respect to connection portion 46, allowing the inclined portion to act as a longitudinal stop for the magnetic member 28 without the need for the tail 51. In still another embodiment shown in FIG. 9, a magnetic member 61 has a male member 63 engaged into female depression 65 of a longitudinal frame 131. The male/female engagement provides a stop for the magnetic member 61 in both longitudinal and transverse directions. In another embodiment (not shown), the male/female portions of the engagement between the magnetic member and the frame are reversed. The male/female engagement can be utilized on the front window frame with the pivotal cover 44 (not shown). In FIG. 10, the magnetic member has an encapsulation header 71 that serves as an air or rain shield.

(18) In FIG. 7, a magnetic member 128 has a rearward extension 129 that is laterally stopped by spaced-apart latch plates 40. The elongated portion of the magnetic member 128 has horizontal magnetic attractive interface with the windshield. The rearward extension has vertical magnetic attractive interface with the latch plates 40. A longitudinal window frame 131 has a series of female depressions 65 to allow for multiple fore and aft positions of the fabric portion of the cover (FIG. 8).

(19) The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
