2205282 TELESCOPING COVER FOR STORAGE FACILITIES
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention pertains to retractable covers for storage facilities and more particularly to a telescoping cover having selfcleaning guideways on which it is designed to reciprocate.
2. Description of the Prior Art
Storage facilities may take many different forms, including vehi cular cargo beds and stationary material containment structures. Tops designed to cover such a storage facility generally serve the purposes of providing security against entry by both the weather elements and unauthorized persons. The user, however, must be able to efficiently access the interior of the storage facility; thus, any provision for security must also take into account easy access. In addition, the special case of vehi cular employment is particularly sensitive to the effects of wind when tra veling at moderate to high speed, and provision must accordingly be made to ensure that Integrity of seal between the top and the side walls is retained.
Several solutions have been advanced in the prior art whichare directed at solving the particularly demanding conditions encountered'% vehicular applications. These have generally two rather broad classes of approach: articulating covers, and retractable covers.
Articulating covers are generally composed of a plurality of segments which are designed to hinge upwards, thereby providing access to the interior of the storage area. U.S. Patent 4,615,557 to Robinson disclo- 1 1 - -oj ses a panel cover having two sections which hinge transversely across the bed of a pickup truck and seat on a channel provided along the wall periphery. U.S. Patent 4,313,636 to Deeds discloses a multiple segmented cover transversely hinged across a pickup truck bed, folding forwardly in the bed on an angle iron track. U.S. Patent 4,284,303 to Hather discloses a two piece top which folds longitudinally along the pickup truck bed sing hinged sections on the top of the side walls. All of these solutions require the user to lift a relatively large, unwieldy cover section which could in the process be very difficult under conditions of high wind.
Retractable covers are generally composed of segments which slidably move in relation to the storage facility, thereby permitting access to the interior of the storage area. Generally, these employ three types of methods that utilize either removable segments, accordion folding segments, or fan folding segments. Further, these generally employ a channel of either a 'Cm or 'Un shape which is secured to the longitudinal side walls of the storage facility, which cooperate with a lip at either end of the longitudinal sides of the cover'segments to permit slidable movement in the lonitudinal direction while preventing movement in the transverse and vertical directions.
The removable segment solution is disclosed in U.S. Patent 4,406,493 to Albrecht et al which describes a modular hard top for pickup truck beds, each component of which is slidably secured to the side walls via a OCO shaped channel cooperating with top segment lips.
The accordion folding solution is disclosed in U.S. Patent 4,547,014 to Wicker which describes a generally OCO shaped channel mounted longitudinally on the side walls of a pickup truck. which accepts for slidable movement therein a series of transverse cross members supporting a flexible top material. U.S. Patent 4,285,539 to Cole describes a generally OCO shaped channel secured to the side walls of a pickup truck cooperating with a series of guides slidably moving therein to fold a bow structure supporting a flexible top material using a crank.
is The fan-folding solution is disclosed in U.S. Patent 4,611,848 to Romano which describes a "C" shaped channel mounted interiorly at the top of a- pickup truck's side walls. A series of transverse cross members are movably supported by wheels located in the channels thereby allowing stiff cover panels to be crankably rolled onto a rewind tube. U.S. Patent 4,550,945 to Englehardt describes a fan-folding segmented panel cover which rests on a pickup truck's side walls, utilizing pins for retention thereon. U.S. Patent 4,618,194 to Kirkham et al describes use of OCO shaped channels located interiorly at the top of the pickup truck's side walls which are designed to slidably cooperate with hinged slide bars supporting a plurality of segmented rigid cover panels, permitting folding of the panels forwardly in the bed by means of a motor actuating crank. U.S. Patent 4, 273,377 to Alexander describes use of a NUO shaped track located interiorly at the top side walls of a pickup truck which has a pair of grooves serving as guides for ball bearings that are integral on a bearing guide which support in turn a plurality of transverse support members. U.S. Patent 4,252,362 to Campbell describes use of generally C" shaped channels mounted to the Interior side walls of a pickup truck in which are located a plurality of wheels that support, at each end, cross members which in turn support a flexible top material; the channel is designed to permit various amounts of the bed to be closeably covered.
U.S. Patent 4,289,346 to Bourgeois discloses a retractable cover which employs a first embodiment utilizing the accordion fold method, whereby a generally OCO shaped channe. I positioned at the top of the iide walls of a pickup truck is used to guide wheels connected to cross supports of flexible top material. In a second embodiment, a plurality of rigid top panels of Progressively smaller dimension are designed to telescope successively one receivably into the other, with movement being enabled by utilization of the above mentioned Cu shaped channel and wheel combination in cooperation with a motorized mechanism.
is In the prior art, there remains the problem of providing a cover for a storage facility, in particular a mobile vehicular facility, which is easy to operate, fully secure against the elements of weather and unauthorized entry, and substantially unaffected by environmental conditions that may cause debris to build up on the guides. Articulating covers are not easy to use, as mentioned above. Prior art retractable: covers are subject to environmental conditions, particularly sand, dirt, or ice which can get into the 'Uu or wCl shaped channels used to guide reciprocation, causing impaired operability until the inhibiting conditions are removed. Accordingly, a retractable cover is needed which Is substantially immune to these factors, and which yet provides a secure, easy to use covering for a storage facility, in particular those pertaining to truck cargo beds.
SUMMARY OF THE INVENTION
The present invention is directed to solving the need for providing a retractable cover for storage facilities, especially those used in vehicular applications, which is substantially insensitive to environmental debris accumulation on the guideways used to regulate reciprocation.- In the preferred embodiment, a plurality of cover sections in successive mutual telescopically receivable relation are employed, however,'a flexible top material supported by a plurality of rib elements could be used in accordion-fold fashion. A guideway is provided at the top of each longitudinal section of storage facility side wall. Each guideway is constructed of an elongated base which has a generally flat surface from which elongated bosses extend. The bosses are formed of a lower and upper portion. The lower portion mates with the guideway base in lengthwise parallel relation. The upper portion is disposed an the lower portion in lengthwise offset parallel and co-terminal relation. The cover sections have a top which forms a cover for the storage area, from which depend c 1 is mutually opposing sides. Each cover section has a slotted lower terminus which allows one of the bosses on one guideway to be receivably inserted therein such that the cover section is mounted to the guideways. A detent is attached to the lower terminus of the cover section sides to prevent the cover sections from being vertically dislodged from the guideway by &; I interferring action with the offset upper portion of the received boss. Provision may be made for the use of,wheeled load bearing members within the slotted lower terminus to ride along the upper portion of the received boss so as to reduce friction during reciprocation of the cover sections.
Because the guideway contains no NCO or NUN shaped channel that would easily accumulate dirt, sand or ice, and because it is very easily washed or wiped clean, there is virtually no likelihood that accumulation of debris could render reciprocation of the cover sections difficult to accomplish. Indeed, the interaction between the guideway bosses and the cover section slats is such that the respective surfaces are complementarily shaped in close proximate relation thereby causing a wiping action at the forward end of the cover as the cover is moved along the guideways causing the bosses to be cleaned free of debris every time the cover section is extended from the retracted position.
Additionally, the guideway is provided with an OLO-shape along its longitudinal length, one side of which, the base, rests on the top of the storage facility side walls and the other, an extension member depends vertically down the storage facility side wall whereat attachment is 'made of the guideway to the storage facility side walls. By this structure, the guideway is able to transversely reciprocate in response to temperature induced dimensional variations between the cover section sides and the storage facility side walls.
Accordingly, it is an object of the present invention to provide a retractable storage facility cover that is easy to use and provides substan- 1 1 1 J1 tial storage access when retracted and security against the effects of weather and unauthorized entry when extended.
It is a further object of the present invention to provide a retractable storage facility cover hat is designed for use In vehiculir applications, particularly truck cargo beds, that is secure from the elements of weather even when the vehicle is driven at moderate to high speeds.
It is yet a further object of the present invention to provide a retractable storage facility cover which employs guideways for guiding reciprocable action of the cover which because of complementarity of shape between the cover and the guideways, the guideways are self- cleaning and generally impervious to debris accumulation due to the effects of environmental conditions. such as sand, dirt or ice.
It is still a further object of the present invention to provide a retractable storage facility cover which Is of rigid construction and has is mounting means for connection to the side walls of the storage facility which allows for thermal expansivity of the cover in relation to the side walls.

Because the most demanding form of utilization of the invention is in applications Involving motor vehicles, the preferred embodiment has been primarily directed to such employments. However, to those skilled in the pertinent art, it is clear that the principles used in making and using the invention for purposes of retractably covering a truck cargo bed canbe readily adapted for the somewhat more simplistic conditions of operation appurtenant to use in stationary situations. Accordingly, it is to be understood that the description that follows is applicable to other usage configurations, and that, since motor vehicle use is the most complex, it is dealt with in particular hereafter.
i 1 1 f 8 - is While the preferred embodiment hereinbelow described utilizes such a telescoping approach for providing a retractable cover, the present invention may be adapted for use with flexible top covers retracting in accordion-fold fashion. This will be discussed following the discussion of the telescoping preferred embodiment.
Referring now to the figures, Figure 1 shows the inventive retractable cover 10 mounted on the cargo bed of a pickup iruck 12. The invention utilizes a plurality of rigid cover sections,.a first cover section 14 which is movable, a second cover section 16 which is movable, and a third cover section 18 which is stationary, which are of successively larger size so that each is telescopically receivable into the other in the order of the first movable cover section 14 into the second movable cover section 16 and the combination of the first movable cover section 14 and the second movable cover section 16 into the third cover section 18. The cover sections are designed so that each covers a portion of the cargo bed and collectively they cooperate when extended to completely cover the cargo bed. Each is formed having a rigid top 20, 22 and 24, respectively, from which depend mutually opposing sides 26L, 28L and 30L, respectively, where L designates the left or driver's side of the vehicle in Figure 1, forming a generally rectangular box shapt; the right side cover section sides are not shown. The first movable cover section 14 has a rear end wall 32 transversely positioned between the cover section sides of the first movable cover section, which serves to complete the coverage of the area above the cargo bed. The third cover section IS closest to the front of the vehicle cab 33 is stationary relative to the vehicle, and the first and second movable coversections 14 and 16 are telescopically receivable into it. It will be understood, therefore, that at least one movable cover section must be used in addition to the third stationary covev, section 18; the use of the two first and second movable cover sections 14 and 16 in the figures is for illustrative purposes only and not intended to be limiting, as any reason- 1 i 1 1 able number could have been chosen. It will be noticed that the cover sections, when fully extended, form a complete covering of the truck cargo bed. Each cover section when extended is structured to sealingly mate with adjacent panels thereby preventing entry by the elements of weather, suc.h as rain, as well as entry by unauthorized ersons. Additionally, particularly valuable cargo is hidden from sight of passersby.
Figure 2 shows the invention in which the first movable cover sec-. tion 14 has been telescopically retracted into the second movable cover seetion 16. This is enabled by the placement of the first and second movable cover sections 14 and 16 on guideways 34 and 36 that are affixed to the top of cargo bed side walls 38 and 0 thereby permitting the movable cover sections to slide longitudinally along the top of the cargo bed side walls. The exact manner of the cooperative operation of the guideways with the cover sections will be described in detail hereinbelow. It can be seen in Figure 2 that some entry is gained to the cargo bed in the area of the tail gate 42, with the first movable cover section 14 being retracted. The movement of the first movable cover section 14 so that it is telescopically received into the second movable cover section 16 is accomplished by pushing on the end rear wall 32 of the first movable cover section 14 on which is provided a handle 44 for this purpose. Figure 3 shows the result of continued application of force applied to the end rear wall 32, in which the first and second movable cover sections 14 and 16 are now both telescopi.cally received into the third stationary cover section 18. It will be seen that the cargo bed is substantially open, the only remaining covered-area being that occupied by the third stationary cover section 18.
The scenario for extending the cover sections"to again cover the cargo bed is accomplished by pulling on the handle 44, a s wil I be more fully described hereinbelow. As indicated above, slidable movement of the first and second movable cover sections 14 and 16 is accomplished by use of the guideways 34 and 36. The structure of the guideway can be understood by t 1 P f 1 is 1 1 reference to Figures 4 and 5, which shows the left-hand cargo bed guideway 34 located on the driver's side of the vehicle. It will be seen from the figure that the guideway is formed of an elongated base 46 which is substantially flat so it can rest on the top of a cargo bed side wall. The elongated base 46 has along one of its longitudinal sides a downward- ly depending extension member 48. The extension member 48 is used to secure the guideway to an interior side 49 of the cargo.bed side wall 38. Extending upward from the elongated base 46 are two elongated bosses 50 and 52 which extend lengthwise, generally the length of the guideway in parallel relation thereto. Their purpose is to guide the sliding movement of each movable cover section in cooperation with slots 68 and 70 provided in each movable cover section side, respectively.
The exact cooperation between the cover sections and the guideways is shown in Figure 5, which is a cross-sectional view of the invention from the rear of the vehicle, particularly at the top 54 of the left, or driver's side, cargo bed side wall 38. It can be seen from Figure 5 that each of the elongated bosses 50 and 52 have a lower portion and an upper portion. The lower portion of each boss 56 and 58, respectively, is formed of a narrow segment which mates with the guideway elongated base 46 in lengthwise parallel relation thereto and in extending relation therefrom. The upper portion of each boss 59 and 60, respectively, is of generally circular cross-section and is co-terminously disposed in offset relation to one side of the lower portion, of each boss; the surface direction of the lower portion is followed on the opposite side 64 and 66 respectivelyvf the upper portion of each boss. The bosses, therefore,. have a lowerportion and an upper portion which is offset 61, 62 to one side, along the length of the boss. As mentioned above, the first and second movable cover sections 14 and 16 have a slot 68 and 70, respectively, located in their side lower terminus 72 and 74, respectively, running parallel with the side, which allows one of the bosses on one guideway to receivably insert therein such that the cover section is mounted to the guideways. In particular, it is seen that i is the elongated boss 50 is located in the slot 68 of the second movable cover section 16 and the elongated boss 52 is located in the slot 70 of the first movable cover section 14. The mutual separation of the elongated bosses is determined generally by the movable cover section wall thickness, as-shown in Figure 5, there being one elongated boss on each guideway for each ' movable cover section. In order that the movable cover sections are held onto the guideways against vertical forces, a detent 76 and 78, respectively, is attached to the movable cover so as to protrude into the slot. The detent acts to interfere with the upper portion of the boss, retaining the movable cover section from vertical movement. Figure 5 shows that the offset surface 61 and 62, respectively of each boss upper portion, interferingly contacts a detent surface 80 and 82, respectively of the slot in which the boss is received. The detent is removable attached to each movable cover section side lower terminus. Alternatively, it could be an integral part of the movable cover section. A relationship similar to that just described exists between the guideway-boss and the movable cover section slot and detent on the opposite, or passenger side wall of the vehicle cargo bed, not shown. The stationary third cover section 18 is attached to the guideways 34 and 36 in any convenient manner using any conventional fastener, such as a screw 87 and a mounting bracket.
While the use of elongated bosses of the shape shown is preferred, other shaped bosses are intended. The structural criteria is to provide a shape which provides for only substantially longitudInal sliding movement of the movable cover sections along the guideway. This is accomplished by 1) using a boss which is receivable into the slot at the lower terminus of each movable cover section, permitting only substantially longitudinal movement; and 2) providing an offset in the upper portion relative to the lower portion of the boss which enables an interference with the detent on the movable cover sections, thereby preventing vertical-movement of the movable i i 0 I,,- is cover sections from the guideway. Each movable cover section side slot is structured so that its surface shape is mutually complementary to that of the surface of the boss inserted within it, where the detent provided in the movable cover section wall forms part of the surface of the slot. Thus, the cover section slot shape coupled with the detent shape form a surface complementary to the boss surface. When the movable cover section is slid along the guideway, the complementarity of the movable cover section slot surface and boss surface creates a wiping action on the boss at the leading edge 83 of the movable cover section slot surface, as particulary shown in Figure 6, cleaning off any accumulated debris that may have been present on the boss. This may be particularly understood by reference to Figure 3. A pulling action on the handle will cause the cover sections to successively extend. As this occurs, the leading edge of each cover section slot surface will wipe clean the boss surfaces of any dirt, sand or ice that may be present thereon. This is possible because the bosses are of a shape which cannot significantly accumulate clogging debris, which would be very likely to happen in designs using "Uu or "C" shaped channels, coupled with the fact that the slot in the movable cover sections is complementarily shaped to wipingly engage the boss surface as it slides in the extending direction. Thus, the probllem of impaired operation of retractable cover systems due to exposure to environmentally born debris is substantially eliminated.
Figure 6 discloses an alternative embodiment in which a roller bearing system 84 employing a plurality of rollers 86 is used to carry the majority of the second movable cover section weight loading onto the, upper portion of the boss received in the slot of the second movable cover section. Thus, reduces the effort of the user in overcoming friction as the second movable cover section is slid along the guideway. As indicated In Figure 6, the roller bearing system isinserted into a side cavity 91 in the second movable cover section side at its lower terminus, the shape of the slot leading edge 83 of the cover section remains intact, as described 1 1 1 1 1 above, so that the complementarity of the second movable cover section and slot surface boss surface continue in wiping cooperation. Figure 5 shows the roller bearing system in operation on the second movable cover section 16. The first movable cover section would have a similar roller bearing system and side cavity.
Figure 7 discloses an alternative embodiment of the guideway in which the extension member 48 is made to incorporate a curvature 88 along its downward length. It will be seen from the figure that this curvature' is located between where the extension member fastens 90 to the cargo bed sidewall and its connection 92 to the elongated base 46. The purpose of the curvature in the extension member is to allow for thermal expansion of the cover sections in a transverse direction between.sidewalls of the cargo bed. As an example, decreased transverse cover section width on cold days is accommodated by a spring biased distortion.in the extension member 48 toward the interior side of the cargo bed sidewall 49, as shown in the figure.
Figure 8 shows the way in which the cover sections are caused to be in mutual telescopically receivable sealing relation. The forward end 94 of the first movable cover section 14 has an upwardly disposed member 96 on its top 20 which contacts a downwardly disposed member 98 in a forward end 100 of the top 22 of the second movable cover section 16 when the first ' movable cover section 14 has been fully telescoped into the second movable cover section 16 along the direction of arrow A. Further pushing on the rear of the first movable cover section 14 at the handle 44 causes a collective sliding movement of the first and second movable cover sections,14 and 16 telescopically into the third stationary cover section 18 along arrows A -and B. In the reverse direction, pulling on the handle 44 causes the first movable cover section 14 to extend separately along arrow C until the forward end of the upwardly disposed member 96 of the top 20 of the first movable cover section 14 strikes the rearward end of a second downwardly disposed member 102 at a rearward end 103 of the top 22 of the second 1 0 4 movable cover section 16 in the manner shown from the interaction 104 between the second movable cover section 16 and the third stationary cover section 18 in the figure. Further pulling on the first movable cover section 14 causes collective motion along arrow C of the first movable cover section 14 with the second movable cover section 16 until both movable cover sections are fully extended telescopically out of the third stationary cover section 18. Gasket materials 106 are employed to ensure sealing relation between the cover sections.
Operation and use of the Invention can be understood as follows:
The invention is installed on the vehicle by first attaching the guideways on the top of the cargo bed side walls. Next, the first and second movable cover sections are positioned so as to have their upwardly and downwardly disposed members on each top, respectively, in interlocking relation, as shown in Figure 8, then slid onto the guideway. Lastly, the is stationary cover section is attached on the guideway. 7 The cover sections, when completely extended cover the guideway, prevent debris from accumulating on it as well as the cargo bed. When the movable cover sections are retracted by a sliding action along the guide way, the bosses are exposed to the environment and, consequently, the poten 1 20 tiality of debris build-up. When it is desired to extend the cover sec tions, the complementarity of the leading edge surface of the slot in the lower terminus of the movable cover sections and the surface of the bosses causes the bosses to be wiped clean of any debris that has accumulated as the movable cover section is pulled along the guideway, preventing-caking of debris and consequent impairment of operation of the sliding-action of the movable cover sections, as would occur in channel guided cover systems.
While a self-cleaning function is achieved, the interference action of the bosses and the detents, prevents removal of the cover sections vertically out of the slot. Additionally, the mechanism for mutual telescopic receivabi- i Ai 1 1 - is - lity of the cover sections, as Shown in Figure8, also positively provides end points of travel on the guideway for the sliding of the movable cover sections.
While the preferred embodiment has been directed to a telescoping configuration of rigid cover sections, it is possible to use the invention in situations where the rigid cover section is replaced by a flexible top material which is supported by a plurality of rib elements each having a pair of ends, each end connecting with the guideway In the manner described for the rigid panel configuration. Such configuration would utilize an accordion-fold method for retracting the cover and each rib element may slide along a singl. e boss on each guideway. Each end of each rib element forms a lower terminus which is configured in the manner described above for interfacing with the guideway and its boss through means of a slot and detent, which surfaces are in mutual complementary shape to the surface of the boss. A description of a flexible top embodiment that could be adapted to be used with the guideway means described in the present invention is disclosed in the above referenced U. S. Patent 4,289,346.
is 1 A further embodiment of the invention is shown in figures 9 and 10, figure 9 being a sectionaL view showing the cooperative, reLationship between a rib and the guideway, figure 10 being a part sectionaL side view of figure 9.
To those skilled in the art to which this invention appertains, the above described preferred embodiment may be subject to change or modification. Such changes or modifications can be carried.out without departing from the scope of the invention, which Is intended to be limited only by the scope of the appended claims.
