Abstract
A tonneau cover assembly, such as for a compartment at the rear end of a vehicle includes a housing which has an opening in one side and a rotatable spool therein. A tonneau cover, i.e. a cover, extends through the opening, is secured to the spool, and wound on the spool such that the tonneau cover is movable between a fully extended position and a fully retracted position wherein the tonneau cover is fully wound onto the spool. A torsion spring biases the tonneau cover towards the fully retracted position. The tonneau cover includes a generally rigid flap attached at an outer end of the tonneau cover which has a handle thereon. Two stop members are attached to at opposite sides of the flap, and they are sized to prevent the flap from fully entering the opening and winding onto the spool. Each stop member has a wedge-shaped section which narrows in an inward direction towards the housing such that the stop member is wedged into the opening so as to inhibit the flap from vertically oscillating within the opening. The stop members also include projections for securing the stop members to supports to hold the tonneau cover in an extended position.

Description
Background of the Invention
This invention relates generally to a cover apparatus which selectively covers or exposes a compartment area, particularly a cargo area of a vehicle, such as a rear tonneau compartment area.
Tonneau cover assemblies usually serve as a means to conceal the contents of the tonneau cargo area, or rear compartment, of a hatchback, station wagon, pickup truck or other type of vehicle which may have luggage, equipment or other personal items contained therein.
There have been a variety of tonneau cover assembly devices developed for the tonneau compartment of a vehicle. However, this invention most specifically relates to a retractable tonneau cover assembly which has a flexible tonneau cover that is retracted into a housing by a biasing means.
One general example of a known retractable tonneau cover assembly is shown in U.S. Pat. No. 4,776,625 wherein a roll-up cover member 52 is retractable into a housing 54 and can be unwound to obscure the view of the contents of the vehicle compartment 12.
Another known retractable tonneau cover assembly is shown in FIGS. 10-12. In the latter known vehicle tonneau cover assembly, the tonneau cover assembly includes a flexible tonneau cover portion and a more rigid flap secured to the outer free end of the tonneau cover. The flap has two stop members on the bottom side thereof to prevent the flap from entering the opening in the housing.
However, this flap is not rigidly secured when the tonneau cover is retracted within the housing. This permits the flap to vibrate when the vehicle is traveling along a roadway. Among other things, this vibration is distracting to the driver and causes wear marks on the cargo area walls. In some instances, vibration absorbing mounts have been placed on the cargo walls between the flap and the walls so that the wear and the noise are reduced.
FIG. 10 is a perspective view of the latter prior art tonneau cover assembly. The device includes a housing 110 which is mounted on the inside walls 111 of the vehicle at the front of the cargo area immediately behind the back of the rear seat. The housing 110 has an opening 112 through which the tonneau cover 113 passes to enter or exit the housing. The tonneau cover 113 has one end secured to a spring biased spool (not shown) within the housing 110 which biases the tonneau cover 113 towards the fully retracted position. A generally rigid flap 114 is secured to the outer free end of the tonneau cover, and the flap is shaped to conform to the shape of the rear wall of the cargo area. Two rubber stoppers 115 are mounted on the bottom side of the flap 114 which serve to prevent the flap 114 from entering the opening 112 when the cover 113 is retracted. In addition, separate fasteners 116 are mounted on the opposite lateral side edges of the flap 114 in order to engage fasteners (not shown) on the side walls 111 adjacent the rear wall of the vehicle to maintain the tonneau cover 113 in the fully extended, or open, position.
As noted, the flap edge 114a must conform to the shape of the rear wall of the cargo area, which is generally an arcuate shape. Among other things, the arcuate nature of the flap edge 114a and the size of the housing prevent the flap 114 from being stored in the housing when retracted. Consequently, the weight of the flap 114 causes the flap to droop downwardly, and potentially engage the side wall 111, as noted. Further, road irregularities cause the flap 114 to vibrate against the side walls 111 and against the housing 110. This vibration, thereby, creates irritating noises within the vehicle cabin. In addition, wear marks are, thus, made on the side walls 111.
Added shock absorbing material 117 has been sometimes placed on the bottom of the flap 114 adjacent the lateral side edges to dampen the vibration of the flap against the side walls 111 and to reduce wear marks on the side walls 111.
Prior to the present invention, the known vehicle retractable tonneau cover assemblies had problems related to, among other things, noise, wear, excess numbers of parts and excess weight, etc.

Furthermore, the present invention is easy to manufacture. For example, when a single piece stop member is constructed, it can be formed easily, and efficiently attached to the tonneau cover. Furthermore, when the single stop member includes a variety of functional parts, no additional members need to be added; thereby, reducing construction time, costs, and weight.
Furthermore, the present invention does not require an elaborate housing structure in order to achieve the advantages and functions of the invention.
(2) Reduction Of Vibrations And Reducing Of Wear: In the present invention, frictional wear inside the vehicle is eliminated. Thereby, among other advantages, preserving higher quality of the product over extended use.
In addition, noise resulting from vibrations during use when in a retracted state is also eliminated. Thereby, among other advantages, creating greater driving comfort and safety.
The present invention enables a rigidly secured tonneau cover which is economically beneficial and which minimizes the parts required, and which is far superior to the prior developed devices.
The above and other (a) objects, (b) advantages, (c) features and (d) aspects of the present invention will be more readily perceived from the following description of the preferred embodiments thereof taken together with the accompanying drawings and claims.

Detailed Description of the Preferred Embodiments
As illustrated in FIG. 1, the tonneau cover assembly 1 according to the preferred embodiment of the invention is situated in the rear cargo area of a vehicle (the tonneau compartment area).
In use, the tonneau cover 2, shown in FIG. 2, of the tonneau cover assembly 1 is moved between two specific positions, (1) a fully retracted position (shown in dark lines in FIG. 1 ) wherein the compartment area is visible and accessible from the back of the vehicle and (2) a fully extended position (shown in dotted lines in FIG. 1) wherein the tonneau cover covers the tonneau cargo area and wherein the tonneau cover is fixedly held by a connection portion of the vehicle (as discussed below).
Referring to FIGS. 2, 4 and 5, the tonneau cover assembly according to the instant invention comprises a housing 3 and a tonneau cover 2 which is movable in and out of the housing 3 between the fully extended position and the fully retracted position.
The housing includes an elongated opening 4, see FIG. 4, in one side thereof. The opening 4 has a sufficient width to accommodate the width of the tonneau cover portion which enters the housing when retracted.
The illustrated tonneau cover 2 includes two sections, (1) a generally rigid flap section 5 and (2) a flexible cover section 6.
As further shown in FIGS. 2, 4 and 5, the flap 5 is mounted on, or otherwise formed at, the outside free end of the flexible cover 6. The flap (1) helps to maintain the structural shape of the tonneau cover, but also (2) as in the prior art tonneau cover, the flap is shaped to conform to the rear wall of the vehicle. As illustrated in FIG. 2, the side of the housing having the elongated opening is preferably generally linear. On the other hand, the rear end wall of the vehicle is usually non-linear, or a generally arcuate configuration, such as also seen in FIG. 2.
Therefore, the flap is formed with a width Q, as indicated in FIG. 2.
Preferably, the flap is formed with a plastic material. In addition, the rigidity of the flap portion can be due to or enhanced by an inner frame structure.
The flexible portion 6 of the tonneau cover 2 can be formed, as an example, with a polyester basic fabric material. In addition, as shown in FIG. 4, a stiffener rod 7 can be included in the flexible cover section 6 in order to enhance rigidity in a lateral direction.
As also shown in FIG. 2, the flap further serves as a means for providing a handle 8 (as discussed below).
As shown in FIGS. 3-5, one end of the flexible cover 6 extends into the opening 4 of the housing 3 and is secured to a spool 9 which is rotatably mounted within the housing. The tonneau cover 2 is wound onto the spool 9 as the tonneau cover 2 is moved from the fully extended position to the fully retracted position.
In order to provide a winding force, at least one torsion spring 10, shown in FIG. 3, located inside the spool 9 biases the tonneau cover toward the fully retracted position shown in FIG. 5. The torsion spring 10 can be connected in any manner as would be readily understood by one of ordinary skill in the art. For example, the spring 10 can be attached at one end to a fixed central shaft which passes therethrough and at another end to the inside of the spool 9. Although a torsion spring 10 is the preferred embodiment, it should be apparent that other types of winding means may be employed, i.e. other devices capable of exerting a turning force on the spool 9 in order to wind the tonneau cover to a retracted state, including, as examples, a motor device or other resilient means. In addition, although preferred for compactness, etc., the spool 9 does not necessarily have to be hollow with a winding means therein, but it can be a solid shaft with an external winding means.
Furthermore, although a winding means is the preferred form of retracting the tonneau cover 2 because, among other windings, a winding means has size and material minimizing benefits, the present invention also contemplates other biasing means for moving the cover into a retracted position in the housing such that the tonneau cover 2 is movable between a fully extended position and a fully retracted position. For example, the tonneau cover 2 may be slid or otherwise moved into a housing, without winding.
As noted above, the flap 5 further serves as a means for providing the handle 8, as shown in FIG. 2. As should also be apparent, one can extend the tonneau cover 2 by pulling on the handle 8.
As should also be apparent from this description herein, in the preferred construction, the tonneau cover 2 is constantly urged into the retracted position, so that if one releases the handle 8 prior to fixing it in the fully extended position (as discussed below), the cover 2 will return to the retracted state.
FIGS. 2-3 also illustrate mounts 11 which secure the housing onto side supports within the vehicle cargo area behind the rear seat of the vehicle. As would be apparent to one of ordinary skill in the art, the mounts 11 may be of many constructions and are not limited to the illustrated structure. The mounts 11 should be capable of firmly holding and attaching the housing within the vehicle, such as to the side walls 12 of the vehicle. As examples, brackets, clamps, or other connections can be used. The mount members 11 are, thus, configured to be mounted on side supports of the cargo area of the vehicle.
In the illustrated embodiment, as shown in FIGS. 2, 4 and 5, the flap 5 has two stop members 13 attached thereto which prevent the flap 5 from entering too far into the housing 3, by winding too far onto the spool 9, as the tonneau cover 2 is wound into the fully retracted position. Each stop member 13 is secured to a respective lateral side edge 14, 15 of the flap, as shown in FIG. 2.
Each stop member 13 has a wedged-shaped section 16 at a rear side of the stop member 13 which faces inward towards the housing 3. The wedge-shaped section 16 is formed by inclining the upper and lower surfaces of the stop members over a portion as illustrated. The widest portion of the wedged-shaped section 16 is greater than the height h of the opening so as to ensure a secure fitting wedge connection.
Although two stop members 13 are preferred, additional, or possibly fewer, stop members 13 could be included, although such would clearly be less desirable, such as from the standpoints of stability, secureness and/or minimization of parts.
In operation, when in the fully retracted position, each of the stop members 13 is wedged into the opening 4 in the housing, as shown in FIG. 5. The wedging action created is preferably sufficient to rigidly secure the stop members 13 against the housing 3 and to prevent the flap 5 from vibrating or oscillating, such as (a) in a vertical direction by the contact with upper and lower walls 17, 18, respectively, of the opening 4, and (b) in a horizontal direction, or in a pivotal direction about the opening, by the wedging forces acting thereon.
The spring force of the torsion spring 10, the size and weight of the flap portion 5, and the materials of the stop members 13 and housing 3 are among the factors considered in determining the wedging action. One of ordinary skill in the art would recognize that these factors could be varied depending on circumstances.
In one preferred construction, the stop members 13 are made of a synthetic resin material, and the housing 3 includes a trim extrusion material 19 on the upper and lower edges 17, 18 of the opening. The trim extrusion material 19 can be used to enhance wedging contact and/or reduce wear of the respective parts.
FIGS. 6-9 more specifically illustrate the most preferred structure of the stop members 13.
As shown in the preferred embodiment of the invention, an extension securing means 20, see FIG. 6, is formed integrally with the stop member 13. In this regard, a lateral protuberance 21 is provided which extends to the side of the tonneau cover 2 as shown in FIG. 2, and which engages a receptacle on rear end side supports 22 (generally indicated in FIG. 1) in the cargo area side wall when the tonneau cover 2 is in the fully extended position, whereby the cargo area is covered by the tonneau cover assembly when the protuberances 21 are engaged with the rear end side supports.
As shown in FIG. 2, each lateral protuberance 21 extends a sufficient distance to enable the protuberance to be accommodated in a holding means on the side of the vehicle without interference from other portions of the tonneau cover. Although a lateral protuberance 21 is shown as a preferred securing means, because of, among other things, its economic and minimizing benefits, other securing means such as clips and the like are also contemplated.
As shown in FIGS. 4-9, in the preferred embodiment of the invention, a retraction limiting means 23 is also formed integrally with the stop member 13. In this regard, the stop members 13 each have two wedge-limit projections 24 on their upper surfaces 25, see FIG. 6, extending generally vertical from the stop member and having a generally vertical inner contact surface 26 facing inward towards the housing 3 which can engage an outer abutment front wall 27, see FIG. 4, of the housing 3 adjacent the opening 4 so that the flap 5 cannot be retracted into the opening.
However, although less preferred, it should be clearly understood that these projections 24 may be deleted without departing from the spirit of the invention. Although two projections are preferred, clearly more or less projections could be employed without departing from the spirit of the invention.
Therefore, as discussed above and as shown in FIGS. 6-9, in the preferred embodiment, each of the stop members 13 is a "single" piece member which incorporates a variety of functions in the one "single" piece, whereby economic advantages and minimization of parts and weight is greatly enhanced.
That is, a "single" piece stop member according to the most preferred embodiment incorporates the following features and their functions:
(1) retraction limiting means 23, i.e., including as the wedge limiting projections 24 which limit inward movement of the tonneau cover;
(2) vibration damping means and wear reducing means, i.e., including the wedge-shaped section 16; and
(3) extension securing means 20, i.e., including the lateral protuberances 21.
Thus, in the preferred construction, the present invention combines these features into a "single" element, thereby minimizing weight and the number of parts for assembly. However, although clearly less preferred, the present invention also contemplates using separate members in order to separately contain the above three features, alone or in various combinations.
In order to secure the stop members 13 onto the tonneau cover 2, the stop members 13, in a preferred embodiment, include a slot 28 extending fully across the width of the stop members 13 in a first direction and extending only partially across the width of the stop members 13 in a second direction, as shown in FIGS. 4, 5, 7 and 9. In this manner, the stop members 13 are divided into an upper extension 30, see FIG. 7, which extends over the flap and a lower extension 29 which extends under the flap, while the stop members 13 straddle the lateral sides 14, 15 of the flap 5. Preferably, in order to secure the stop members to the flap 5, two rivets 31 are secured within through holes 32, as shown in FIGS. 4 and 5.
As also shown in FIGS. 4 and 5, preferably, the slot 28 in the stop members has a larger front dimension 33 and a narrower rear dimension 34 at a rear side of the wedge-shaped portion 16. In this manner, the wider flap cross section is accommodated in the larger front dimension and only the narrower flexible cover cross section is accommodated in the narrower rear dimension. Among other things, this (1) helps to securely hold the flap 5 within the stop member 13, i.e., helps prevent the flap from being pulled out of the stop member 13, (2) enables the flap to extend partially into the housing, and (3) allows for a narrower wedge size at the rearmost side of the wedge-shaped section 16, i.e., due to the narrower width of the flexible cover cross section.
In a preferred embodiment, the stop members 13 are formed by molding--and preferably molding a "single piece". However, although less preferred, this invention also contemplates using other known means to form the stop members. Further, although clearly less preferred, the present invention also contemplates forming each of the stop members 13 from separate members which are later combined to form the unitary single piece.
In addition, the housing 3 of the invention is shown to be a single `casing` member as illustrated, wherein the upper and lower walls are at upper and lower edges of the opening and wherein the outer abutment front wall is at a front of said opening. However, the terminology "housing" used in the claims is defined to include that the housing 3 can be formed with the outer abutment front wall 27 and/or the upper and lower walls 17, 18 "separate" from the basic `casing` structure into which the tonneau cover is retracted. Thus, the housing 3 may include separate portions, e.g., with a basic `casing` and upper and lower walls attached to the side walls 12 and fixed relative to the opening in the basic `casing` of the housing 3. However, clearly, it is preferred to have these portions as part of the basic `casing` of the housing 3, as illustrated, for economic, material minimizing and other benefits. In either circumstance, it should be understood that the upper and lower walls 17, 18 are located adjacent to the opening.
It will be apparent to those skilled in the art that the embodiments described may be varied as discussed above and in other manners, such as to meet particular specialized requirements, without departing from the true spirit and scope of the invention as claimed.
