Definitions

• the present invention relates generally to vehicle covers and more particularly to covers that can easily be removed from a vehicle mounted storage compartment or containment tube and moved into a covering position around the car.
• the invention also relates generally to the configuration of such vehicle covers for fitting around the vehicle which provides trouble-free retraction into a stored position within the containment tube.
• the invention relates to the mounting arrangement of the containment tube and the storage thereof in the vehicle trunk compartment when the cover is not in use.
• the present invention overcomes the problems encountered in prior art vehicle cover devices by providing a containment tube which is pivotally mounted within the trunk compartment of the vehicle and is stored within the trunk compartment when not in use.
• the containment tube is pivotally swung outwardly from the trunk to a second position located exterior of the trunk whereby the trunk lid may be closed and the cover withdrawn from the containment tube.
• the containment tube is hollow and generally cylindrical in shape and possesses a sufficient volume to accommodate the rolled leader segment and flexible cover therein.
• the containment tube also has a longitudinally extending slot formed therein to permit ingress and egress of the cover and leads.
• the unique cover of the present invention comprises a flexible fabric of nylon, for example, having a shape to overlay the roof, front, rear and side portions of the vehicle.
• the cover has leading and trailing edges.
• the leading edge of the cover preferably has a front section of an elastic fabric, with a rigid guide wand attached thereto and is adapted to be secured to the front bumper region of the car.
• the side and trailing edges of the cover include a ribbon or band of elastic material sewn around the perimeter thereof to provide for a snug fit around the lower regions of the rear bumper and side fenders.
• a leader segment constructed of an elastic material is secured at a first end to a rotatable spool positioned within the containment tube and secured at a second end to the flexible cover at a spaced distance approximately one-quarter to one-third the cover length from the trailing edge of the cover.
• This configuration reduces the number of spool revolutions necessary to retract the cover into the containment tube since the cover is pulled into the tube in a doubled-over fashion until the rear section of the cover is completely retracted into the containment tube.
• the spool within the containment tube is preferably rotated by an electric motor which is powered by the vehicle battery.
• a remote control circuit and remote actuation device is also preferably employed to activate the motor when the cover is to be retracted and wound within the containment tube.
• the cover In use, the cover is unwound from the take-up spool of the containment tube, either in a free wheeling or power assisted mode, by the user who grasps and directs the guide wand at the leading edge of the cover.
• the elasticized front section at the leading edge of the cover may include a cut-out portion to fit around the license plate and/or bracket at the front bumper in order to provide a convenient attachment scheme.
• the cover In the installed condition, the cover is completely removed from the containment tube such that the elastic leader segment extends outwardly from the containment tube slot a distance to permit the trailing edge of the cover to be grasped and pulled rearwardly to cover both the containment tube and the rear bumper of the vehicle.
• the elasticized border portions at the side edges of the cover simultaneously move downwardly to slip beneath the bottom edges of the fenders along the sides of the vehicle providing a very snug and attractive appearance.
• the containment tube is also completely covered by the vehicle cover and out of view when the cover is in the installed position.
• the trailing edge portion of the cover is pulled away and upwardly from the rear bumper and rear fender areas of the car and allowed to assume a position above the containment tube, i.e., in a position between the containment tube and the rear window of the vehicle.
• the elastic border material is sewn into the cover bottom in a manner that causes the cover to naturally gather in the area of the rear window as soon as the lower region of the cover is unhooked from the rear bumper/fender area.
• the leading edge of the cover is then removed from the front bumper and front fender area of the vehicle and the remote control motor switch is then activated.
• the containment tube is pivotally mounted such that the slot of the containment tube which receives the cover is positioned near or above the surface of the trunk lid deck so that there is minimum surface contact with the cover to decrease the chance of snagging as the cover is reeled.
• the heavier elasticized fabric leader material is first wound around the rotating spool of the containment tube which then guides the cover as it is reeled within the containment tube to provide virtually trouble-free reeling and storage.
• a safety overload or torque overload device preferably in the form of a cyclic magnetic switching system or in the form of a spring- loaded torque plate, may be employed within the motorized drive unit in order to sense any snags which may occur during the cover take-up operation.
• Such unavoidable cover snags may result from the cover catching on a side mirror of the vehicle or on a door handle or the like.
• the torque overload device senses any increased tension on the cover and the take-up spool or senses a stoppage of rotation and immediately shuts off the motor in order to prevent overloading thereof and/or ripping of the cover. The obstruction is removed and the motor restarted to complete the winding operation.
• the containment tube is pivotally moved to its stored position within the trunk compartment and the trunk lid closed and locked with the containment tube and cover safely stowed therein.

• Figure 11 is a partial perspective view of the front of the vehicle with the cover of the invention installed thereon.
• the vehicle cover system of the present invention generally designated 2 is shown in the fully installed condition surrounding a vehicle generally designated by reference numeral 4.
• the cover system 2 includes a flexible cover portion 6, the details of which are shown in Figure 5, and a containment tube 8 mounted adjacent a rearward end of the car trunk.
• An elasticized leader segment 10 connects the cover 6 to a rotatable spool 9 located within the containment tube 8.
• the elastic leader segment 10 is sewn or otherwise attached to the fabric cover 6 at an attachment area 10 ' .
• a smaller segment 11 is attached to the leader 10 by way of a zipper 13, preferably of nylon which, in turn, is connected to the spool at edge 11'.
• the flexible cover 6 is preferably constructed of a lightweight nylon material.
• a variety of synthetic and natural materials, including nylon, dacron, cotton, acetylated cotton, and blends of natural and synthetic materials may be used as the primary material for the fabric cover 6.
• the preferred material is nylon because of its light weight, strength, cost, and resistance to mildew and the like.
• the cover 6 also is constructed of a fabric having a light color, so as to reflect the rays of the sun away from the vehicle to thus keep it cool. Due to the fact that the cover material is in intimate contact with the vehicle surface, ideally a cover with a light color on the outer side and a dark color on the inner side is preferred. In this manner, the light outer color reflects the sun away from the cover surface while the darker color on the under side absorbs heat radiated and conducted from the vehicle's surface beneath, thereby transmitting heat away from the covered vehicle's surface.
• the cover 6 includes a leading edge 12 and a trailing edge 16 adapted, respectively, for placement at the front and rear bumpers.
• the cover also includes side edges 14 which extend between the leading and trailing edge portions on opposite sides of the vehicle.
• the cover 6 preferably includes a ribbon-like band of elastic border material 15, on the order of about 1/4 inch wide, sewn around its perimeter.
• the band of elastic ribbon-like border 15 extends from the leading edge 12 around the sides 14 to the trailing edge 16 to permit the peripheral edges of the cover to fit snugly around the lower regions of the vehicle body as shown in Figure 1.
• the leading edge 12 of the fabric cover 6 also includes an elastic fabric front section 18 which extends rearwardly therefrom and is joined to the cover 6 by way of a stitched seam 19, for example.
• the elastic front section 18 carries a rigid, rod shaped guide wand 20 which is fitted around a loop-like bead 52 formed at the end of section 18; see Figure 7.
• a cut-out area 22 is formed within the elastic front section 18 which may conveniently fit around the front license plate bracket for securement purposes.
• the lower front bumper area of the vehicle 4 may be fitted with a pair of small clamps or like means for holding the wand 20 in place (not shown) .
• the cover 6 of the present invention represents a significant improvement over prior covers which are reeled into storage housings, principally due to the unique feature of the elastic leader segment 10 which joins the cover 6 to the rotatable spool 9 of the containment tube.
• Elastic leader 10 is, by way of example, about 24" in width, which is approximately the length of an entry slot 24 formed in the containment tube 8, Figure 2.
• the leader 10 is also, for example, about 2 feet in length from the attachment seam 10' with the cover 6 to the terminal end
• the location of the elastic leader segment 10 relative to the cover 6 is important and, in this regard, we prefer to place the seam 10' joining the leader segment 10 to the cover 6 approximately one-quarter to one- third the cover length from the trailing edge 16. For example, if the cover 6 has a length of approximately 16 feet from the leading edge 12 to the trailing edge 16, the leader segment 10 would preferably be affixed at 10' to the cover 6 between about 4 to 5 feet from the trailing edge 16. In this manner, an aft section of the cover 6 is defined as the section extending from seam 11' to the trailing edge 16.
• the aft section of the cover 6 extends rearwardly to cover the containment tube 8 and the rear trunk and bumper portions of the vehicle when the cover is in the installed position as shown in Figure 1. Conversely, when the cover 6 is to be removed, as shown in Figure 4, the aft section is lifted from beneath the rear fenders and bumper area of the vehicle to assume, by virtue of the elastic border 15, a position above the containment tube 8. In the position shown in Figure 4, the side edges 14 of the cover 6 assume a posture, due to the elastic leader segment 10, extending diagonally from the area of the front bumper to a point forward of and slightly above the inlet slot 24 of the containment tube 8.
• the take-up tube is activated to reel in the leader segment 10.
• the cover 6 follows the leader 10 in a very neat and orderly fashion due to the high position and feeding alignment afforded by the elastic leader 10 and location of the containment tube adjacent the top of the trunk lid 5. The retraction of the cover is also facilitated since the cover is pulled into the containment tube in a doubled-over or double-layered configuration until the entire aft portion of the cover is retracted.
• the containment tube 8 is fitted with a pair of spaced-apart mounting straps 26 which include hinged fittings 28.
• the straps 26 are adapted to be secured to a rear wall of the trunk compartment of the vehicle 4.
• the mounting straps 26 are preferably of a high strength stainless steel material of relatively thin gauge, for example, 0.60 inches thick to permit the trunk lid 5 to close over the straps 26 when the containment tube 8 is outside, in the operable position shown in Figures 1, 2 and 4.
• the straps may also be constructed of stainless steel mesh or plastic.
• the leader segment 10 is preferably constructed of an elastic-like stretchable material, for example, the material sold under the trademark "Spandex” is particularly suitable. This same fabric is also suited for use in the front section 18.
• the front bumper area of the vehicle 4 may also be equipped with "C- shaped spring clips (not shown) to engage and retain the tube-like guide wand 20 when the cover is in the extended position shown in Figures 1 and 4. Retention spring clips are useful for those vehicle designs which do not possess a protruding license plate bracket for engagement with open slot 22 of the front section 18.
• the spool 9 of the containment tube 8 can be rotated either manually, by spring tension, or by a motor assist drive.
• the containment tube 8 and spool 9 may be constructed in a telescoping fashion with slidable nesting sections to accommodate various sizes and weights of vehicle covers.
• the telescoping action is but one of many various forms the containment tube 8 may take within the context of the overall invention.
• the containment tube 8 may be manufactured from either plastic or metal pipe and cut to length with the slot 24 formed through the sidewall by appropriate means along its longitudinal length.
• a pair of end plates 30 are secured to the ends of the containment tube 8.
• the take-up spool 9 is rotatably mounted preferably on bearings within the containment tube 8. As shown in Figure 6, spool 9 may be rotatably driven by a drive motor 32.
• a 12 volt DC 100-150 rpm motor having a wireless control receiver and receiver/motor interface logic and circuitry, generally indicated as 34, is connected thereto and mounted within a chamber formed between the end plate 30 and a motor mounting plate 36.
• the take-up spool 9 is made up of two tubular shafts 38 and 40 mounted for rotation at their ends within stationary end plates 30 and 36.
• a central extension rod 42 is slidably fitted within the tubular bores of the shafts 38 and 40 to permit adjustment of the length of the containment tube 8.
• Set screws 44 are fitted within the tubular shafts 38 and 40 to secure the extension rod 42 therein when the desired length is established.
• the drive shaft tubes are preferably constructed of aluminum tubing stock while the extension rod 42 may be of a stainless steel material to provide a strong joint between the rotating members. Of course, other materials may be employed, such as high strength plastic materials for the central extension rod and tubular shafts and end plates.
• the rotatable spool 9 is driven by a motor shaft 46 which extends from the motor 32 through the mounting plate 36 and into the tubular bore of the shaft member 40.
• a set screw 48 or like keying element engages the sidewall of the tubular shaft 40 to cause the spool 9 to rotate with the motor driven shaft 46.
• the edge 11' of the elastic leader 10 is fastened to the take-up spool 9 by way of an attachment segment 11 which is connected to the main leader 10 preferably by a zipper 13, or by snaps, or by a Velcro-type fastener. Having a zipper in the attachment segment 11 permits the cover to be removed from the spool and containment tube for washing, cleaning, waterproofing and the like, or for thorough drying purposes.
• the attachment segment 11 is secured to the spool 9 by either slitting the spool, inserting and fastening the end of the leader into the slit; or by using mechanical fasteners such as screws, rivets, tape, adhesive materials or the like.
• the attachment segment 11 may be constructed of elastic material similar to the leader segment 10, however, this is not absolutely necessary.
• the width of the attachment segment 11 and the leader segment 10 are several feet in width and substantially are of the same dimension or slightly less than the length of the slot 24 formed in the containment tube 8.
• the cylindrical containment tube 8 may be configured in cross-section as a circle or it may assume an elongated eccentric or oval shape as shown in the cross- sectional view of Figure 7.
• the entry slot 24 for the cover is formed by two inwardly formed curling lips 50, which may conveniently be formed by way of an extrusion, for example.
• the leading edge 12 of the front portion 18 has a bead portion 52 formed therealong, which is adapted to be fitted into a hollow interior 54 of the control wand 20.
• the wand 20 has a longitudinal slot 56 formed therein to permit the wand to be slid over the cover and to permit the beaded portion 52 to reside within the hollow interior 54.
• the diameter of beaded portion 52 is larger than the width of the slot 56 and hence, the guide wand remains attached to the end of the cover 6 by way of this interference fit. End caps are fitted at each end of the guide wand.
• the wand 20 also preferably contains a widened channel portion 58 which 0/05648 _ , 2 _ retains a remote control transmitter unit 60, preferably by a snap fit therein.
• the remote control unit 60 has a switch or button 62 for activating the unit and subsequently sending a signal to the radio receiving control means 70 mounted adjacent the motor 32, or other means mounted in the containment tube 8.
• the containment tube 8 also preferably contains a plurality of spaced-apart drain holes 64 formed through a lower surface thereof to permit accumulated water from the cover 6 to drain therethrough. The drain holes 64 also permit entry of air into the containment tube to maintain the cover in a lower humidity environment within the confines of the containment tube.
• FIG. 8 is a schematic showing one presently preferred embodiment of the control circuitry useful in connection with the present invention.
• the wireless remote control means 60 houses a switch button 62 and a radio frequency transmitter 66.
• a wireless receiver station 68 mounted in the containment tube 8, houses a wireless control receiver 70, with a conventional receiver antenna 72, receiver/motor interface logic circuitry 74 and the drive motor 32.

• the wireless control receiver 70 is located between the motor mounting end plate 36 and the end plate 30 and is activated by a radio signal 76 transmitted from the radio frequency transmitter 66, which, as stated above, may be housed in the guide wand 20.
• the transmitter control unit 60 is preferably unsnapped from the wand and carried by the vehicle operator so as to prevent unauthorized removal of the car cover from the vehicle.
• a radio signal 76 ultrasonic, infrared, microwave or other transmission media could also be used as a wireless control link between the remote unit 60 and the receiver station 68.
• the cover drive motor 32 is activated through a motor/receiver interface logic and circuitry housed in black box 74, which also contains a relay system which may be either solid state logic, or mechanical, to activate the motor 32.
• the circuitry logic is preferably designed such that the remote motor control button 62 must be depressed continuously to permit the operation of the winding/unwinding drive motor.
• Limit control switches 17 may also be used to turn the motor off when the cover has reached either its fully extended, or fully retracted, positions.
• the circuitry is also designed such that the motor rotation may be reversible with a single button control.
• FIG. 9 A further motor control shut-off scheme is shown in Figure 9 which provides a safety shut off in the event of cover snagging and functions as a torque overload device.
• the take-up spool 9 of the containment tube 8 has a rotatable end disc 78 attached thereto for rotation adjacent the stationary motor mounting end plate 36.
• the disc 78 has a plurality of permanent magnets 80 affixed around the perimeter thereof.
• a stationary magnetic sensor 82 is affixed to the mounting plate 36 to monitor the oscillating magnetic field created by the magnets as the spool end disc 78 rotates past the sensor.
• the magnetic sensor 82 is connected to a periodic magnetic field analyzer circuitry represented by black box 84 which, in turn, is wired to the motor 32.
• the sensor 82 continuously monitors the oscillating magnetic field generated as the magnets 80 pass in front of the sensor as the take-up spool end disc 78 rotates during a normal cover winding operation.
• the sensor 82 immediately recognizes a cessation in the oscillating magnetic field and the solid state periodic magnetic field analyzer circuitry 84 immediately causes the motor to shut off, thus preventing an overload in the motor and/or damage to the cover 6 if it were, for example, snagged on a side mirror, door handle, or the like.
• control button 62 on the remote transmitter 60 is pressed and the motor 32 is restarted if additional winding of the cover is required.
• the magnetic sensor control unit is also useful for automatically stopping the motor 32 when the wand 20 reaches the tube 8 to shut the motor off at the end of the winding cycle.
• the take-up spool 9 and containment tube 8 may also be equipped with a manually operated crank handle or like device to permit manual winding of the spool 9 as an alternate embodiment. Such a manual feature may also be incorporated with the motorized embodiment to provide a back-up system for winding the spool 9.

• the cover 6 is, in the embodiment of Figure 10, manually withdrawn from the containment tube and pulled over the vehicle using the guide wand 20 to apply the fabric cover 6 over the surface of the vehicle 4. The pulling movement of the cover causes the spool 9 to rotate and thus stores the needed energy in the springs 86 as they are compressively wound by the rotating spool 9.
• the wound springs 86 are then locked in place after the cover has been reeled in by setting the solenoid pin 94 in one of the indexing holes in the disc 92.
