Abstract
John D. Allen WALL STAKE FOR VEHICLE SIDEWALL PANELING
ABSTRACT OF THE DISCLOSURE
Disclosed are wall stake structures adaptable for removable insertion into flat bed trailer and truck vehicles provided with a plurality of depending pockets whereby drayage vehicle sidewall pan-eling is supported by intervening upright wall stakes. The wall stake comprises: an upright semi-rigid post having a header and a foot which is insertable into a flat bed vehicle pocket; a plurality of distinct spacers each extending transversely forwardly of the post; and an upright guide-plate abutting the respective spacers and ultimately attached to the post, the guide-plate being transversely more resilient than is the post and also laterally liberally wider to provide two transversely resilient channels for supporting sidewall paneling. The spacers pref-erably comprise a plurality of vertically separated distinct tubular bushings which are removably attached to the post and guide-plate thereby facilitating manipulation of the paneling and permitting use of different thickness paneling. At the header upper end of the post is provision for a secure and reliable seat to permit engagement with a transversely extending topbow canopy support.

Description
1~8~Z~7~
SPECIFICATION
Overland draya~e vehicles of the flat bed type common-ly include a plurality of depending pockets along the truck or trailer sides. Occasionally, depending upon the type of cargo to be hauled, such pocketed flat bed vehicles are pro-vided with temporary sidewalls comprising stakes uprightly removably inserted into the flat bed pockets and elongate upright paneling (usually of plywood material) ~eing up-rightly removably supported by the intervening wall stakes.
Among the prior art wall stakes are those described in United States Patents Nos. 3,097,880, 3,162,224, 3,794,375;
3,837,702; and 3,940,179. -Wall stake constructions of the prior art suffer from one or more of the following disadvantages and deficiencies.
Transversely shifting cargo loads can place a great deal of stress upon the wall stakes and the intervening elongate paneling. If wall stakes are made too rigid, a transversely shifting cargo load can cause fracture or permanent deforma- ~ -tion. Even localized deformation at the wall stake channel will make subse~uent dismantling of the paneling sidewalls extremely difficult, if not impossible. On the other hand, if wall stakes are made too transversely resilient through-out, they are unable to sustain the paneling and shifting cargo weights. A seeming solution to this dilemma had been to provide the wall stake preponderantly of base and alloy metals. However, such metallic wall stakes under actual roadway use conditions oftentimes fracture, or eventùally become so corroded as to become practically impossible to remove from the metallic flat bed vehicle. Another problem common with prior art wall stakes is that they do not pro-vide a reliable connector for the vehicle transversely ex-tending topbow. Yet another problem associated with prior 12'~9 art wall sta~es is that t~ey cannot readily accommodate side-wall paneling of different thickness.
It is accordingly the general object of the present invention to provide an improved removable wall stake for flat bed vehicles sidewall paneling which overcomes the several disadvantages and deficiencies of prior art wall stakes.
The invention in one aspect provides a wall stake adaptable for removable insertion into a flat bed vehicle provided with a plurality of depending pockets, said wall stake being adaptable for uprightly supporting vehicle sidewall paneling and ;~
comprising: a)an upright post extending along a vertical-axis from a header at the post top-end to a foot at the post bottom-end, said post having an upright periphery surrounding said vertical-axis and including a uniplanar front-surface of a finite lateral-width, a left-surface, and a right-surface, said post having a cross-sectional size of at least about three square inches whereby said post is semi-rigid in the transverse direction when ;
its foot is removably emplanted into a vehicle depending pocket;
b) a plurality of vertically separated and distinct tubular ~ -~

Referring initially to Figures 1 and lA which typify prior art relative to upright wall stakes for supporting sidewall paneling. A typical flat bed pocketed vehicle might ~ ~ -take the form of trailer "T" having wheels "W", drawbar "Y", and horizontal flat bed "F" rearwardly terminating at "R".
Incrementally spaced along the sides of flat bed "F", and customarily at two-feet intervals, are depending pockets "P" ~
of a few inches finite-depth. The typical prior art wall ~ -stake "H" depicted in Figure lA is of extruded metal having a uniform H-shaped cross-section to provide two upright channels for the upright terminii of removably supported paneling 100. The upper and lower laterally extending hori-zontal terminii of paneling 100 are respectively indicated~
as 105 and 106 (at flat bed "F"). The lower end foot part of wall stake "H" is removably inserted into vehicle pocket "P" while the upper portion is provided with an offset tubular seat "J" for supporting the depending lower end "BB"
of the transversely extending topbow "B" which in turn sup- ~
ports a canopy (not shown). ~`
Figures 2-5 depict a representative embodiment 9 of the wall stake concept of the present invention. Wall stake 9 comprises an upright post 10 extending along a vertical-axis lOA from a header portion lOH at the post top-end 11 to -~
a foot lOF at bottom-end 12 and which is removably emplant-~`
~lZ7~ -able into fl~-t bed ~ocket ~ n~erted post 10 is semi-rigid in the transverse direct.i`on and preferably o~ non-metallic construct~on whereby also corrosion at bed "F" does not occur and the foot lOF is mechanicall~ shaveable to con-form to the pocket shape and si~e encountered. Regularly rectangular cross-sectional sizes and shapes for post 10 are desireable, in which cases there are four upright elongate surfaces including rear-surface 13, front-surface 14 of a finite lateral-width "LW" a left-surface 15, and a right-surface 16 of a finite transverse-width "TW". To provide a transversely semi-rigid non-metallic emplanted post, which i5 preferably of oak wood, the rectangular cross-sectional area should exceed three square inches and with the TW/LW
ratio being within the range of one-half to two~
Canopy supporting topbows "B" are customarily sta-tioned at four-feet intervals, and thus, one-half or more the wall stakes used should have seating means e.g. "J", for a topbow lower end ''BB'I. Herein, the post might be pro-vided with a circular post-bore 17 extending downwardly from ~;
top-end 11 along vertical-axis lOA for a minor proportion of the post upright height 11-12(which is typically a 4 feet height). A metallic pipe 18 having a circular pipe-bore is frictionally secured within post-bore 17 to provide a seat ~or topbow lower end "BB". Topbows "B" exert ap-preciable transverse stresses upon its seating means e.g.
"J", but which the concentric and metallic pipe seat 18 herein is admirably suited to withstand. In this vein, a twisted metallic wire 19 provides a girth-band located immediately below and surrounding post top-end 11 and co-elevational with pipe 18, which girth-band 19 prevents the non-metallic post header portion lOH from being ruptured by the forces exerted by topbow "B".

Cooperating with and attached to post 10 and forward- :
ly transversely spaced therefrom a finite transverse-length "TL" is a guide-plate 30 which in its lateral-distance 35-36 liberally exceeds the - 5a - ~
lO~Z'~9 po9t lateral-wldth "LW" by a l~tiO of about two. Thus, the up~ight left-edge 35 and ri~ht-edge 36 Or guide-plate 30 might protrude llke lateral-extents "LE" beyond the po~k lertward and rightward terminii 15 and 16. Guide-plate 30 1~ necessar~ly ~truekurally re~iliently ~lexible a~ by having a relativel~ thln dimen310n "GT" between lts rearward 33 ~nd it~ rorward 34 broad ~ur~aces, which 6iven-thicknes~

The forwardly transver~ely e~tendln~ spaoer means and the attachment mean~ between post lO and gulde-plate 30 are preferably located at v~rti~ally separated and di~tlnctly lsolated location~.
~OI~LZ'79 Accordingly, between each distinct spacer means station (20), the guide-plate 30 is desireably transversely resilient for its entire lateral-distance 35-36 as indicated in phantom line "D". Herein each distinct spacer means station 20 comprises a tubular cylindrical bushing 21 having a rear-ward inner-end 22 abutting post front-surface 14 and a for- ;~
ward outer-end 23 abutting guide-plate rear-face 33, trans-verse distance 22-23 being "TL". A headed fastener bolt 24 at each spacer station 20 passes horizontally through post 10, thence bushing 21, and finally guide-plate 30 midway edges 35 and 36. Completing the fastener arrangement for-wardly of guide-plate 30 and surrounding bolt 2~ are: wash-er 25, lock-washer 26, and finally nut 27 threadedly engaged with bolt 24. Accordingly, with such removably secured fastener means 24-27, the bushing 21 can be readily replaced with another bushing 21 but of a different transverse-length "TL". This allows a selectable transverse-length "TL" for the two wall stake channels and equivalent to the transverse -thickness of the paneling (e.g. 100) available for or other-wise appropriate to the flat bed cargo carrying vehicle.
Preferably, the inside diameter of removahly secured cylin-drical spacer bushing 21 slightly exceeds the diameter of bolt 24, this loosely surrounding relationship facilitates ready removal of paneling from the two upright channels of each wall stake.
For the Figure 5 wall stake embodiment having the ~
quide-plate bottom-edge 32 nearer post bottom-end 12, the ;
wall stake channels secure the upright endward terminii 101 of elongate paneling. However, sidewall paneling utilized is oftentimes of four-feet and even eight-feet lateral lengths. As previouslyEointed out, pockets "P" are commonly spaced at two-feet increments along the flat bed cargo- - ' `

carryin~ vehicle. Accordingly, paneling (100) is oftentimes additionally supported by wall stakes (99) located inter-mediate the paneling endward terminîi 101, such as at verti-cally notched portions 102 extending downwardly of panel top-edge 105. For such purpose, and as indicated in Figure 5A, with intermediately employed (102) wall stakes 99, the guide-plate bottom-edge 32 is located much nearer to post top-end 11 than to bottom-end 12. For example a guide-plate height 31-32 about twelve-inches would be typical. In such situa-tions, the spacer means e.g. 21, are located within the down-wardly notched intermediate portions 102 of paneling 100.
After many re-insertions and removals of sidewall paneling from the wall stake channels, the upright terminii 101 might eventually become worn drastically thinner than the channel transverse-length "TL". To compensate for such panel wearing, one might select a bushing of appropriately shorter transverse-length (e.g. 22-23), or even select a softer structural material for the post 10 whereby further tightening of nut 27 will partially embed bushing 21 therein which effectively shortens the transverse-length between post and guide-plate.
From the foregoing, the construction and operation of the wall stake for vehicle sidewall paneling will be readily understood and further explanation is believed to be un-necessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not deslred to limit the invention to the exact construc-tions shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.

After many re-insertions and removals of sidewall paneling from the wall stake channels, the upright terminii 101 might eventually become worn drastically thinner than the channel transverse-length "TL". To compensate for such panel wearing, one might select a bushing of appropriately shorter transverse-length (e.g. 22-23), or even select a softer structural material for the post 10 whereby further tightening of nut 27 will partially embed bushing 21 therein which effectively shortens the transverse-length between post and guide-plate.
From the foregoing, the construction and operation of the wall stake for vehicle sidewall paneling will be readily understood and further explanation is believed to be un-necessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not deslred to limit the invention to the exact construc-tions shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.

1. A wall stake adaptable for removable insertion into a flat bed vehicle provided with a plurality of depending pockets, said wall stake being adaptable for uprightly supporting vehicle sidewall paneling and comprising:
a. an upright post extending along a vertical-axis from a header at the post top-end to a foot at the post bottom-end, said post having an upright periphery surrounding said vertical-axis and including a uniplanar front-surface of a finite lateral-width, a left-surface, and a right-surface, said post having a cross-sectional size of at least about three square inches whereby said post is semi-rigid in the trans-verse direction when its foot is removably emplanted into a vehicle depending pocket;
b. a plurality of vertically separated and distinct tubular bushing spacers each located substantially halfway between the post left and right surfaces and extending a given transverse-length forwardly perpendicularly from the post front-surface; and c. an upright structurally resilient guide-plate abutt-ing said spacers and being attached to the post with a plurality of distinct fasteners each extending transversely through the post, the tub-ular bushing spacer, and the guide-plate said guide-plate having a finite given-thickness defined by a pair of transversely separated broad faces one of which includes the rear-face of said guide-plate located at the spacers and the other of which includes the front-race of said guide-plate, said guide-plate having a bottom-edge located some finite height above the post bottom-end and a top-edge located immedi-ately below the post top-end, the guide-plate also having a pair of substantially parallel upright edges including a left-edge and a right-edge separated by a finite lateral-distance bearing a ratio of at least two compared to the post lateral-width whereby said guide-plate upright edges extend substantially like lateral-extensions beyond the post left and right surfaces so as to provide a pair of similar paneling channels defined by the post and the rear-face of the guide-plate, the guide-plate given-thickness being sufficiently thin such that the guide-plate is more transversely resilient than is the emplanted post, and a vertical separation between each of the respective distinct spacers sufficiently great such that the entire guide-plate between said spacers is transversely resiliently deflectable over the entire lateral-distance thereof.
a. an upright post extending along a vertical-axis from a header at the post top-end to a foot at the post bottom-end, said post having an upright periphery surrounding said vertical-axis and including a uniplanar front-surface of a finite lateral-width, a left-surface, and a right-surface, said post having a cross-sectional size of at least about three square inches whereby said post is semi-rigid in the trans-verse direction when its foot is removably emplanted into a vehicle depending pocket;
b. a plurality of vertically separated and distinct tubular bushing spacers each located substantially halfway between the post left and right surfaces and extending a given transverse-length forwardly perpendicularly from the post front-surface; and c. an upright structurally resilient guide-plate abutt-ing said spacers and being attached to the post with a plurality of distinct fasteners each extending transversely through the post, the tub-ular bushing spacer, and the guide-plate said guide-plate having a finite given-thickness defined by a pair of transversely separated broad faces one of which includes the rear-face of said guide-plate located at the spacers and the other of which includes the front-race of said guide-plate, said guide-plate having a bottom-edge located some finite height above the post bottom-end and a top-edge located immedi-ately below the post top-end, the guide-plate also having a pair of substantially parallel upright edges including a left-edge and a right-edge separated by a finite lateral-distance bearing a ratio of at least two compared to the post lateral-width whereby said guide-plate upright edges extend substantially like lateral-extensions beyond the post left and right surfaces so as to provide a pair of similar paneling channels defined by the post and the rear-face of the guide-plate, the guide-plate given-thickness being sufficiently thin such that the guide-plate is more transversely resilient than is the emplanted post, and a vertical separation between each of the respective distinct spacers sufficiently great such that the entire guide-plate between said spacers is transversely resiliently deflectable over the entire lateral-distance thereof.
2. The wall stake of Claim 1 wherein the post has a regular rectangular cross-sectional shape of a finite transverse-width and id is of wooden structural material; and wherein the guide-plate is of resiliently flexible metallic sheet material.
3. The wall stake of Claim 2 wherein the post is provided with a post-bore extending downwardly from the post top-end along the vertical-axis along a minor proportion of the post upright height;
wherein a metallic pipe having a circular pipe-bore seat is secured within the post-bore; and wherein there is a girth-band tightly surr-ounding the post header above the guide-plate top-edge to prevent the wooden post from splitting during periods when a vehicle topbow is downwardly engaged into the pipe-bore seat.
wherein a metallic pipe having a circular pipe-bore seat is secured within the post-bore; and wherein there is a girth-band tightly surr-ounding the post header above the guide-plate top-edge to prevent the wooden post from splitting during periods when a vehicle topbow is downwardly engaged into the pipe-bore seat.
4. The wall stake of Claim 3 wherein the guide-plate bottom-edge is located nearer to the post top-end than to the post bottom-end whereby to accommodate notched medial portions of very elongated paneling.
5. The wall stake of Claim 1 wherein the guide-plate bottom-edge is located nearer to the post top-end than to the post bottom-end whereby to accommodate notched intermediate portions of very elongated sidewall paneling.
6. The wall stake of Claim 1 wherein the respective spacers comprise tubular cylindrical bushings; and wherein each distinct fast-ener passes transversely through the post, the tubular spacer bushing, and the guide-plate.
7. The wall stake of Claim 6 wherein the respective spacers loosely surround the fastener means to promote ready removal of panel-ing from the stake upright channels; and wherein the fasteners comp-rise threaded bolts removably secured to the post and guide-plate to facilitate replacement of said spacers having different transverse-lengths appropriate to the selected paneling thickness.
