CA2122396A1 - Sun visor for motor vehicles - Google Patents

Abstract

An adjustable sun visor for motor vehicles consisting of a main shaft which secures and supports a base plate, which plate then accepts and allows a second plate to telescope and move back and forth. Given two designs, the main shaft may include a hinge to allow the visor to be moved to any desired position. In its fullest extension, the visor could equal the length of prior art visors and when telescoped, the visor would reduce to about half its fullest extension.
The plate into which the other plate telescopes contains a spring release mechanism which controls the release of the telescoped plate. Both plates are covered in upholstery material and may support, for example, a mirror and/or light.

Description

This invention relates to a manually operable sun visor appropriate to all manner of automotive vehicles to shield the eyes of the driver and front seat occupant from the sun's rays while driving.
A common current type of sun visor is one which is secured immediately above and in front of the driver and front seat passenger positions in an automotive vehicle. These visors are usually comprised of a single plastic oblong base plate (possibly with a soft plastic overlay) covered with a protective pile cloth fabric. The plate is secured to the inside roof structure of the car, typically by a single quarter inch round metal rod at one end and by a clip in the ceilng of the vehicle at the other end. The metal rod is the main shaft and it allows the visor to be flipped down to any desired position just a~ove eye level and immediately in front of the front seat occupant or rotated to the side window position.
These prior art visors have one primary function..... that of shieliding the eyes of the front seat occupants from the rays of the sun while the car is being driven. Further, in recent years, visors have been used as a base to attach a mirror and/or light and in some cases to store small pull out plates to address the specific shortcomings of the large single plate eg the sun's rays coming in corners, below the visor, etc. In addition, the appearance of the visor has been enhanced. Each of the following prior art sun visor patents address a different aspect of the visor's structure and aesthetics but none researched, including these, address the safety and ease of movement features identified in this patent application : U.S. Pat # 5,054,839 focuses on an aesthetically enhanced appearance and improved structure;
U.S. Pat # 5,011,211 recommends an improved manufacturing process; Canadian Pat # 1,325,823 addresses the multiple visor issue; U.S. Pat # 5,152,573 and U.S. Pat # 5,016,938 focus on blocking the sun's rays below the existing single plate unit for shorter drivers; U.S. Pat #'s 5,104,174 and 5,042,867 address internally stored plates to be used to block the sun's rays around and about the single plate and U.S. Pat #'s 4,950,021 and 5,080,420 address multiple visor shields at the front and side windows at the same time.

The major difficulty of existing visors occurs when the visor needs to be moved from the front window position to the side window position. This movement could occur with the visor flap in its 'resting' position, ie horizontal to the roof of the car or in the 'flap down' position, protecting the eyes of the driver from the sun's rays.
Due to the length of the visor, as the driver swings it from the front to the side position, the visor makes direct ~~ /Y

21~2396 contact with the driver's head regardless of whether the flap is in the 'resting' or 'flap down' position.
The head contact even occurs in the 'resting' position because the visor's ability to move smoothly over the driver's head depends directly on the ability of the driver to execute this awkward manoever, the height of the driver within the car, the driver's positioning in his seat and the engineering installation of the visor..... if any one or more of these variables interferes with the movement, the visor will make contact with the driver's head. To minimize head contact with the visor, the driver is forced to lower his head or move it backward and/or to the side. There is no alternative.
Visors are approximately 37-50 cm's long. The distance of the driver's head from the metal rod fastener in the upper left corner of the car's interior, to a comfortable driving position is normally about 16-25 cm's.
The fact that existing visors make contact with the driver's head unless he/she moves it out of the way is a significant and dangerous design flaw which this invention seeks to correct. During the second or split second that the driver's eyes are off the road ..... ..anything could happen or begin happening.. ....specifically loss of control, disorientation, etc........ and probably has. The inventor feels strongly that some car accidents on the road are the direct result of the driver losing control...... over reacting or under reacting to a situation or perceived situation which may or may not have occurred while his/her head was moved to allow the visor to pass.
Further, there is another significant problem. If the driver is wearing eye glasses, the visor, swinging across in front of the driver's head may inadvertently touch the glasses and knock them askew, causing momentary panic in the driver or worst case, knock the glasses off the head of the driver.
This latter situation could have a disastrous affect, resulting in a car accident which could prove fatal...... and probably has.

The primary inventive idea of this invention is that of having a sun visor made up of two separate portions with one telescoping in parallel with the other. This idea, allows for the visor to become approximately half its length, resulting in minimal to no interference with the driver's head when being swung into the side window position and back again. The passenger also receives the benefit of the visor's reduced length however the situation is not as critical as the driver's.
It is one object of this invention to provide an adjustable sun visor assembly for a vehicle including, a bracket for 2122~9~

attaching said assembly to said vehicle; a dual arm unit pivotally attached to said bracket, said unit including a base arm, a base sleeve arm and a hinge; a visor including a base plate and a slide plate wherein said base plate is attached to said base arm and said side plate is slidably mounted on said base sleeve arm, such that said visor can be moved from side to side by pivotal movement of said dual arm unit in said bracket; said visor can be moved from an up or down position (or vice versa) by pivoting the visor about said hinge; and said slide plate can be moved with respect to said base plate by sliding movement of said slide plate on said base sleeve arm to provide an elongated sun visor.

It is another object of this invention to provide an adjustable vehicular sun visor assembly including a bracket for attaching said assembly to said vehicle, an arm pivotally attached to said bracket, and a visor including a base plate and a slide plate, wherein said base plate is pivotally attached to said arm, and said slide plate is slidably mounted to said base plate such that said visor can be moved (1) from side to side by pivotal movement of said arm with respect to said bracket, (2) from an up or down position (or vice versa) by movement of said visor with respect to said arm, and (3~ from an extended to a collapsed position (or vice versa) whereby said slide plate is moved horizontally with respect to said base plate to provide an elongated sun visor.

Figure 1:
The visor illustrated in Figure 1 is the plan view from the driver's perspective in the 'flap down' position, ie showing the visor as it would look pulled down in front of and just above the driver's eyes.
In the embodiment shown in Figure 1, the radical design change of the visor from prior art is immediately obvious.
Specifically, the introduction of the Dual Arm Unit 1, 2 and 3, the hinge 4 on the main shaft, the two plates 6 and 7 and the design and location of the Clip Arm 11. The visor could be covered in a deep pile cloth consistent with existing prior art except on the top and bottom of Slide Plate 7 which make direct contact with Base Plate 6 parts.
This visor invention is designed to replace existing prior art visors within existing vehicles and be included as part of the manufacturing process of new vehicles. The Bracket 5, to attach the visor to the auto, is consistent with existing visor brackets and as a result the entire visor unit can be installed with the screws available. The visor's Dual Arm Unit will rotate within the bracket as today but the flap movement's vertical control will come from the hinge on the Dual Arm Unit. There are two arms, Base Arm 2 and Base Sleeve Arm 3, extending from the Dual Arm Unit. Base Arm 2 supports the Base Plate 6, while Base Sleeve Arm 3 and Track 9 accept and allow Slide Plate 7 to slide back and forth within Base Plate 6. The overlap distance between Edge B and Edge C and the quality of the fitting of Slide Sleeve 8 on Base Sleeve Arm 3, and Flange 10 in Track 9 assures the rigidity and strength of the two plates of the visor. Air holes 17 in both plates, shown in later figures, facilitate the movement of the Slide Plate. The thickness of Clip Arm 11 provides strength and stability to the visor when it is being snapped into and out of the clip at the 'resting' position. A Spring Ratchet Mechanism 12, to be described later, attached to a wall of Base Plate 6 and to Slide Plate 7 by metal bands, provides for the controlled release of the Slide Plate.
Figure 2:
The basic infrastructure of the visor is comprised of the Dual Arm Unit 1 with its two extending arms, Base Arm 2 and 5- ~

2122~96 Base Sleeve Arm 3. The Dual Arm Unit has a hinge 4 to allow the visor to be flipped down to shade the driver's eyes and flipped up to its stationary fixed position. The Dual Arm Unit goes beyond the hinge and is secured to a Bracket 5 which is fastened with screws into the overhead roof of the car's interior the same as prior art visors.
The Dual Arm Unit is the frame on which the entire visor superstructure rests. ThiS unit is hollow to the point where the two arms begin their extension to allow for the running of electric wires as desired. Certain sections of the Dual Arm Unit may be solid metal ie the Base Arm and/or the Base Sleeve Arm.
The Dual Arm Unit 1 begins as a single metal rod permanently fastened to a Bracket 5 in such a way that the Dual Arm Unit may rotate within the Bracket to allow the entire visor to swing to various positions yet provide the fixed stable base required. The Bracket 5, is a round metal disk which is attached by two screws to the roof of the vehicle holding the entire visor in place.
Immediately below the Bracket 5 on the Dual Arm Unit is a Hinge 4 which forms a part of the rod and therefore must allow for the passing of the electrical wires through it. If this is not possible then the wires may have to skirt around the hinge and then be put back in to the rod. The design of the hinge must have at least 90 degree movement to allow the visor to flip down and flip up and the ability to stop and hold the visor at any desired position. In existing sun visors the oblong plate rotates on a single base metal shaft which has the ability to provide this requirement. ThiS
cannot occur in this design because the Base Arm 2 is permanently fixed to the Base Plate 6.
The second arm, the Base Sleeve Arm 3 is also a metal extension on which the Slide Plate 7's Slide Arm Sleeve 8 is mounted. The Base Sleeve Arm 3 has a low friction surface to allow the Slide Arm Sleeve 8 to move easily on it. Further, the Base Sleeve Arm 3 is designed with a 'flange stop' 3A, just in from the end to limit Slide Plate 7 from coming away from the Base Plate once mounted on it. The design here is to provide an overlap and thus added strength to the visor structure given that the unit is a two piece one. It is extremely important that the Base Sleeve Arm 3 fit the Slide Arm Sleeve 8 very snuggly to minimize play but at the same time provide ease of movement for the complete Slide Plate 7.
Figure 2A
This figure is a cut away of the Dual Arm Unit showing how it may be designed to allow the Slide Plate 7 to move ~urther into the Base Plate 6. Specifically, this modified dual arm unit 1-1 would allow the Slide Plate 7 to telescope further within the base Plate 6 and therefore reduce even further the distance between the telescoped visor and the driver.
Figure 3:
Base Plate 6 is made of a suitable material; it may be that plastic will suffice. The Base Plate 6, then, is a hollow sleeve or shell like structure, comprised of a solid material at the top to allow for a horizontal bore 2A
throughout its length to just short of Edge B and the formation of a Track 9 at the bottom. The bore, 2A allows the Base Plate 6 to fit snuggly on the Base Arm 2 and be permanently secured therein. Further, the Base Plate 6 allows Slide Plate 7 to fit into it by having the Base Sleeve Arm 3 accept the Slide Arm Sleeve 8 and Track 9 to accept the Flange 10. The Base Plate 6 provides within its shell design, a plug 12A to hold a slow release Spring Ratchet Mechansism 12, Guides 16 for Metal Bands 13, and Plugs 15 to hold screws for a mirror, a light, and/or any other such accessories. The Plate may also be designed to include guides for electrical wiring, not shown.
There may be a need in the overall design for a mechanism to control the movement of the Slide Plate 7 as it travels in and out of the Base Plate 6. Specifically, if the Slide Plate 7 fits into the Base Plate 6 without any movement facilitator other than friction and the push and pull supplied by the driver, or passenger , as the case may be, the Slide Plate 7 will move inward, totally subject to the strength of the push and be totally reliant on the pull of the driver to come back out. In fact, coming back out, could in some circumstances be awkward, ie the driver pulling the Slide Plate out over his left shoulder in traffic. As a result, a ratchet mechanism could be included and used of appropriate design. This mechanism would take control of the Slide Plate as it was pushed in eg a thin metal band attached to the Slide Plate 7 which winds back to a circular spring ratchet mechanism fixed within Base Plate 6. Once the Slide Plate 7 was depressed, the mechanism would release it slowly back to its fullest extension. This action is required to prevent the Slide Plate, if the mechanism were jus~ a spring load action, from jetting back out quickly and uncontrollably and hitting the driver in the head. This controlled action also aids the driver because once he/she depresses the visor in and swings it to the desired position, the Slide Plate automatically returns to its fullest extension.
Figure 3A is the end view of the Base Plate 6, known as Edge A, down the line I-I in Figure 3. This Edge A has two holes bored through, shown as 2A and 20, one to accept the Base Arm 2 and one underneath it to accept Base Sleeve Arm 3. In addition there are a number of small air holes 17 to facilitate the dissipation of the air forced through from ~ - ~Y

The view also shows the placement of where the Base Sleeve Arm 3 would be positioned if the Dual Arm Unit were fitted.
The diagram further shows the Track 9 formed out of the bottom of the plastic Plate 6 into which Flange 10 fits to provide the guide for Slide Plate 7.
This cross section further shows the general placement of screw plugs 1~ for the attachment of a mirror and or a light. Also, the Guide Flanges 16 for the Metal Bands 13 which are an integral part of the spring Ratchet Mechanism 12 are shown, as is the plug 12A onto which the Ratchet Mechanism is secured.
Figure 4 is a plan view of Slide Plate 7. This plate could be made of plastic, and has a bore at the top of the plate running its entire length. The bore is called Slide Arm Sleeve 8 and with the bore going through to Edge D, the hole providing an outlet for the air to escape when the Plate is telescoped inside Base Plate 6. At the bottom of the Plate is Flange 10 which fits into Track 9 and holds the Slide Arm Plate in place as shown in Figure 4A.
The Clip Arm 11 could be moulded as part of the Slide Plate 7 and is thicker, as is shown in Figure 4B, to provide the strength and durability required as it is clipped and un-clipped from a ceiling receptacle, not shown. A modified Clip Arm 11 is shown in Figure 4C to allow the visor to be used in vans. The van extension could even be a pull out.
Further, two flanges 14 are shown on Edge C, to which the Metal Bands 13 of the Ratchet Mechanism 12 would be attached.
Figure 4A is the end view of Base Plate 7, known as Edge C, down the line III-III in Figure 4. This view shows a ~ore at the top known as Slide Arm Sleeve 8 which is mounted onto the Base Sleeve Arm 3 of Base Plate 6 and Flange 10 at the bottom of Plate 7 which is fitted into Track 9 of Plate 6 to provide for the sliding motion of Plate 7 within Plate 6.
Air holes 17 are provided for air dissipation and flanges 14 for attaching the metal bands 13 of Ratchet Mechanism 12.

-Figure 5 is an alternate plan view of the visor showing almost the same construction and design as that in Figure 1, except that this design shows a Single Main Shaft Support Unit 23 consistent with existing prior art visors eg ( see U.S. Patent 5,011,211) The operation of the visor is the same as previously described except that the Slide Plate 7-1 does not have a bore 8 and Base Plate 6-1 does not have a base sleeve arm 3 on which the Slide Plate rides. Rather, as is shown in Figure 6B, the Base Plate 6-1 has a Track 22, into which the Flange 21 in Figure 6C is fitted and rides.
The Flange 10-1 is consistent in design and use with Flange 10, as is Track 9-1 and Track 9. Other parts are consistent with the first design.
Figure 6A is the end view of the Base Plate 6-1, known as Edge AA, down the line IV-IV in Figure 5. This Edge AA shows a Bore Hole 19 for the mounting of the Single Main Shaft Support Unit 23. It is recognized that the mountimg of this Unit 23 may not be as simple as placing it into a bored opening 19 within the Base Plate 6-1 and that construction may very well require a more complex attachment process to ensure the Unit 23 is secured to the Base Plate 6-1. Again, as shown in Figure 3A, there are air holes 17 bored through to facilitate the dissipation of air.
Figure 6B is the end view of base Plate 6-1, known as Edge BB, down the line V-V in Figure 5. This Edge BB shows the hollow body of the Base Plate 6-1 with dotted lines showing where the Single Main Shaft Support Unit would be and the two Tracks 22 and 9-1, along with other parts consistent with that shown in Figure 3B. The change in design here is the replacement of the Base Sleeve Arm with the Track 22 into which the Flange 21 of the Slide Plate 7-1 fits and allows the Plate 7-1 to slide back and forth within the Base Plate 6-1. Other actions would be the same as that described in 3B.
Figure 6C is the end view of Slide Plate 7-1, known as Edge CC, down the line VI-VI in Figure 5. This Edge CC shows the two Flanges 21 and 10-1 which are fitted into Tracks 22 and 9-1 respectively, thus allowing the Slide Plate 7-1 to slide within the Base Plate 6-1. Air holes 17 are also shown as they may be required for air dissipation to facilitate the movement of the Plate 7-1. TWo flanges 14 are also shown consistent with that shown on Edge C of Slide Plate 7 for the attachment of the bands of Ratchet Mechanism 12.
Figure 7 is a cut away view of Base Plate showing a Modified Single Main Shaft Support Unit 24; modified in that the main shaft has an Extension 24A, the equivalent of a Base Sleeve Arm 3, attached to it to allow the acceptance of a Slide Plate with a Slide Arm Sleeve. This design integrates the Single Shaft with all of its capabilities of existing prior 9 - /~

art ie allowing the visor to be flipped-up, flipped-down and hold at any point, while at the same time allowing for the telescoping of one plate within the other without the hinge unit noted earlier.
Figure 8A is a cut away of the visor assembly showing a modification to both the Clip Arm 11, known as Clip Arm llA
and the Base Plate 6, known as Base Plate 6-2. Clip Arm llA
is extended over to the Base Plate 6-2 and is attached to it as shown in Figure 8C to allow for greater rigidity of the visor unit and to provide for a 'Stop' 6-2A, built into the top of the Plate 6-2, to prevent the Plate 7-2 from coming away from the Base Plate 6-2.
Figure 8B is a view of the top of the Clip Arm llA showing its shape.
Figure 8C is a cut away end view of Base Plate 6-2 known as Edge BBB down the line VII-VII in Figure 8A. This edge BB8 shows the top of the base Plate 6-2 with its modified track 6-2A-1 on which the modified clip arm llA would fit to provide increased rigidity in the overall visor.
Although it is apparent that specific preferred embodiments of an adjustable sun visor assembly have been described, it is apparent to those skilled in the art that many alternatives and modifications may be made to aspects of the disclosed embodiments without digressing from the spirit of the disclosed invention.
