Abstract

It is a small apparatus that has the suitcase shape and size fixed to the car's roof. It contains a protective cover that can wrap and unwrap the car, completely, automatically, quickly and easily according to the principal of the circumvention or twirling of soft tissue around an axle, producing circular folding. As a result, it saves time and money and economizes water. In addition, it can be also used for cosmetic and touristic purposes to cover roofs, backyards, and swimming pools.

Description

THE AUTOMATIC CAR COVER

Introduction: Technical state:

It is an apparatus used to cover the car automatically, according to a new principal. It can also be used for cosmetic and touristic purposes to cover the roofs, backyards,- and swimming pools. The prior art:

The well-known car protective-cover, which is used manually or semi-automatically, The umbrellas, which are used in the Holy Mosque of ALMADINA, which depend in movement on metallic joints and angles. - The Benefits:

Covering the car full automatically, quickly, and easily It can save time and money and economize water.

The description:

This apparatus consists of: 1-Two bases:

1^st: A flat subbase 59x59 cm attached to the car roof by four small rubber bases, or by air vacuum devices. It has a central axle A (2.5 cm diameter, 30 cm length) of- wide base Fig: 1.

2^nd: A flat upper-base 59x59 cm parallel to the sub-base:

It has an empty round center (8 cm diameter) to permit the cylinder to pass through it freely.

It is holded by a flat arm attached to the central axle A (fig 2). It caries - the spreading units, the motor, and the gear-chains as in Fig: 8, 9, 22.

2- An external plastic cover which has a streamline shape. It bases on the central axle A .Fig5.

3-A small slow electric motor: has the ability to rotate in two directions, fixed to the inferior surface of the upper-base ,its motion axle passes through the upper-base up to- be fixed by a pillow-block-bearing (which is fixed to a special base to the upper-base) ,the motor's axle carries two gears (S 1,S2) .The first depends on one direction ballbearings while the other depends on another ball-bearing that has the opposite direction. Fig (9, 10,11). 4-The four spreading units: - There is a unite at each corner of the upper-base.

Each unit consists of metallic base 8x8x2 cm , Fig 12 ,fϊxed on the upper surface of the upper-base fig 8 , crossed by 4 axles, Figl3,14,23 .three axles are short ,and each holds from bottom a gear ,but the fourth axle (E) holds from bottom a gear( E) and from top also holds a gear (E) . Fig 13,14,15. - So each spreading unit has four gears under the upper-base, Fig 9 , 26 , and one gear over the upper-base .Fig 8 , 14,15.

A gear-chain Gl passes through the four upper gears E (of the four spreading units) on the 4 corners of the upper-base connecting them with the gear Sl (that depends on one direction ball bearing fixed to the motor's axle. Fig 22. - 5-The circular folding unit: consists of: 1-The cylinder C (5 cm diameter 18 cm height) placed on two ball bearings on the central axle A, Fig 3 it can rotate in two directions , it has a gear S3 on its upper part over the upper-base.Fig4,6,7,l 1 2- A gear chain.G2 attaches between the cylinder's gear S3 and the - motor's gear S2.Fig 22.

6- The gears and gear-chains:

One big gear S3 depends on the upper part of the cylinder.

Two gears Sl, S2 depend on two opposite one-direction ball bearings holded on the motor axle fig: 10, 11. - 20 gears: 5 for each spreading unit; Fig 14.

The gear-chainGl delivers the motion from Sl to the four upper gears of the spreading units. Fig 22.

The gear-chainG2 delivers the motion from S2 to S3 (the cylinder's gear). Fig 22.

7- Four plastic chains: - Each plastic chain is made of 30 small plastic pieces attached to each other.The vertical section of the small plastic piece has the shape of the letter (I). The small plastic piece has two external faces .Its horizontal cross section shows small teeth on both faces; Fig 19. These teeth permit the four under gears of the spreading unit to besiege and interlock (gear) with the plastic piece as in Fig 23, 25. - Each small plastic piece has a head and tail .Figl 6, 17.

The small plastic piece is 2 cm height, 1.5 cm width, and 12 cm length , but its actual length after putting the pieces together is 10 cm that its tail (2 cm) inserts inside the next plastic piece's head . The head has two vertical opposed socket pins, and the tail has two vertical small-- opposed holes to connect and articulate with the socket pins, to produce a long plastic chain that can twist horizontally left and right, but cannot twist vertically. The sagital vertical section of the head (Fig 16) is like the letter C (closed from one side), this acts as anti-rotator of the next small plastic piece, Fig 18, (prevents rotating to that closed side direction, but permits to twist the opposite direction) - which is the same rolling direction around the cylinder. The plastic chain is fixed to the cylinder with special bases. Fig 27.

In the vertical level of the plastic piece we find 3.5 degrees of deflection between the sites of the head socket pins and the tail holes sites, (in the same plastic piece), Fig 21.

This is very important to make the plastic chain turn down 90 degrees when 25 plastic pieces depart out the apparatus (3.5degrees multiplies 25 pieces ~ 90 degrees).This angle is necessary to provide the plastic chain the suitable streamline of the front and- back sides of the car . Fig 28.

Each plastic piece has a hanger on its bottom surface. Fig 16,19.

8- Waterproof textile protective-cover:

It has an empty circular center with linearly zipper that extends from outline to the empty circular center. It also has 4 supported cords that extend diagonally from outlines to the- empty center.

The cover is connected to the plastic chains hangers by hooks from the 4 diagonal supported cords; Fig 37,38.

The fig31 shows how the cover curls (folds) around the cylinder.

9-Remote-control unit. - 10-Contact sensors: To cutoff the power at the end of the stages.

11 -Electric wires.

12- The brushes: Made of tough tall plastic fibers distributed on the circumference of the inferior surface of the upper-base, to push and direct the cover down to avoid squashing the cover between the gears. (Fig 29 , 30 )

Fig 21: The deflection of the head's socket pins sites from the tail's holes. there is 3.5 degrees of deflection ,this difference is important to make the plastic chain turns down 90 degrees when 25pieces depart from the apparatus (3.5x25 «

90degree) . This will give the plastic chain enough bending to correspond - with the car surface at back and front sides..

socket pins sites (3.5 degrees) in each plastic piece. This makes the plastic chain curves down 90 degrees at the level of the plastic piece No.25 at the car's front and back sides.

The folding phase: - The motor scrolls in an opposite direction of the spreading. It rolls the gear S2 (as its one direction ball bearing is gearing with this direction).

The gear S2 scrolls the gear chain G2 that rotates the gear S3 and so the cylinder curls with the four plastic chains, which roll around the cylinder with the cover.

When the four plastic chains enter, they pass through the brushes that push the cover- down.

Also when the four plastic chains enter, they scroll the gear (E) which moves the gear-chain Gl that scrolls Sl inactively, because Sl depends on one direction ball bearing that is not gearing in this direction.

So the cover and the plastic chains curl and gather around the cylinder. - The distributed hangers all over the plastic chains carry the cover by hooks attached to the cover's four supported cords.

Contact sensors are used to stop the motor at the end of the two phases, to prevent any damage to the apparatus.

The apparatus is provided with remote-control for auto-motion. - When the cover is folded inside the apparatus, the apparatus can be removed and put in the car's package.

Other designs of the apparatus may be used manually. This demands some simple modifications.

The car can be provided with the apparatus during manufacturing. When we design- it to be a part of the car roof thickness,it rises up to spread the cover when wanted.

And dives down and disappears after folding the cover.

We can replace the plastic chains by other materials such as plastic or long steal flexible blades, steal cords, metal ropes, plastic ropes, supported textile ropes, or plastic chain of different shapes.
