Description
1076~73 The pre8ent invention relates generally to the trans-portation of sheet materials ant, more particularly, to knock-down shipping racks for transporting and storing glazing sheets wherein the racks may be quickly assembled for use and easily disassembled for compact storage.
It was formerly common practice to pack glazing sheets in disposa~le wooden boxes or paperboard cartons for shipment to installers. However, with increasing labor and material co~ts, such disposable packaging is not always economically ~ustified.
Disposal of the waste materials from such packing has also become increasingly difficult chiefly due to ecological factors. More-over, wooden or heavy cardboard cartons offer limited protection from breakage of heavy fragile items such as glass sheets.
Reusable shipping racks have been previously used for shipping glazlng sheets as shown, for example, in U.S. patent No.
3,533,502, issued on October 13, 1970. However, such a prior art rack has not proved entirely satisfactory in that it is not read-ily adapted to carry glazing sheets of different thicknesses and - dimensions. As is well known, the building industry requires a large number of glazing sheets of different sizes as dictated by the various building styles. Thus, large numbers of different size glass sheets are produced and shipped to installers for glaz-ings in such buildings, and several different size racks are re-quired to accommodate sheet3 that vary greatly in size. There-fore, if the racks will not interchangeably accommodate the dif-ferent size sheets, the number of racks which must be maintained is multiplied. The racks represent a sizeable economic invest-ment and thus it is desirable to minimize the number required.
Al80, the increased cost of transporting the empty racks back to the shipper i8 becoming prohibitive.
Briefly stated, the knock-down shipping rack of thls invention, while having utility in the transporting of multiple sheets of flat glass, generally is particularly adapted for re-peated use wherein it can be set up, loaded, transported and, when emptied at its destination, packed in a compact manner for transport back to the shipper. Some of the members forming the rack are ad~ustable vertically, some horizontally, and other members are interchangeable with llke elements of different lengths in order that the rack might accommodate various sizes of flat glass sheets. Thus, only one basic type of rack i8 re-quired thereby providing a ~avings in construction costs as well as storage space for spare racks.
According to the present invention, there is provided a knock-down shipping rack for transporting and storing flat sheets on their edges in an inclined position, characterized by ~ ;
a pair of end members spaced apart in opposed relationship, each said end member having a generally L-shaped sheet supporting sur-face with one of the surfaces supporting said sheet edgeæ, said one surface being inclined inwardly and downwardly at an acute angle to the horizontal plane with the other supporting surface extending upwardly therefrom, a pair of side rails extending be-tween said end members for spacing said members apart in said op- , posed relationship, means for detachably connecting the ends of said side rails to said end members, a tie member mounted for generally vertical ad~ustment on each of said end members, and means for securing said tie member in a selected vertical position relative to said end members.

Referring now to the drawings and particularly to Figs.
1 and 2, there is illustrated a reusable knock-down shipping rack ~ constructed in accordance with the invention and designated in ; its entirety by the reference numeral 20. As disclosed, the rack ~- 20 in it~ assembled condition comprises an open frame in the form of a rectangular parallelepiped structure and generally includes a pair of upstanding sheet supporting end members 21 snd 22 for - .- .
l supporting a plurality of glass sheets 23 on their edges in an ~i :
,~
inclinet pogition, a like palr of horizontal longitutinal tubular side rails 24 for detachably connecting the end supportlng mem-bers together in generally vertical, parallel planes, a like pair of adJustable top tie members 25 for retaining a plurality of in-divitual glass sheets 23 on the supporting ent members, and a like pair of ad~ustable end restraining members 26 for preventing entwise movement of the glass sheets 23 relative to the rack 20.
More specifically, each sheet supporting end member 21 or 22 comprises a front corner post 27 and a rear corner post 28 which are ~oined together by a horizontal bottom sheet support-ing rail 29. As best illustrated in Fig. 2, the sheet support-ing rail 29 extents between ant is rigidly connected as by weld-ing to the lower ends of the corner posts 27 and 28. The top surface 30 of the rail 29 slopes townwardly and inwardly at an acute angle to the horizontal from the front corner post 27 to the rear corner post 28 for supporting the bottom etges of the glass sheets 23 in an inclined position. Lateral support for the glass sheets 23 is provided by an upstanding sheet supporting mem-ber 31 which ex~ends perpendicularly upwardly from the sloping surface 30 of the rail 29 to the top end of the rear corner post .;
28. Thu~, the surface 32,of the upstanding member 31 provides an inclined lateral support against which the substantially upright surface of the innermost sheet of glass 23 rests when it is stand-ing o~ its bottom edge on the inclined surface 30 of the rail 29.
In order to provide for ease in assembling and disas-sembling and at the same time provide for a rugged rack assembly, each end of the side rails 24 is detachably connected to its ad-~acent corner post by a peg and socket device 33. Thus, as in-dicated in Fig. 2 and specifically illustrated in Fig. 3, the corner posts 27 and 28 of eacp end supporting member 21 and 22 are pro~ided with a horlzontally pro~ecting tubular peg 34 whereln the pegs pro~ecting from the end member 21 face the pegs pro~ectlng from the end member 22. Each peg 34 is adapted to be received ln an open end 35 of the slde ralls 24. Each end of the slde ralls 24 is locked to lts correspondlng peg 34 by a headed pin 36 whlch is placed through a set of registerlng aper-tures 37 provided in each end of the ralls 24 and the peg 34.
The pln 36 18 retalned ln place by a halrpln cllp 38. Also, each ent of the slde rails 24 is provlted wlth a dependlng angle-shaped bracket or gusset 39, a slde of whlch bears agalnst the correspondlng corner post to provlde a stable Jolnt structure.
As lllustrated ln Flg. l, the front corner post 27 may be formed of two separable lnterflttlng sections 80 that a sec-tion of each front post can be readlly removed ant replaced on the frame 80 as to permlt ready access for loadlng and unloading of the glass sheets 23 on the rack 20. Thus9 each front corner post 27 18 comprlset of a bottom section 40 and a removable upper sectlon 41. At the lower end of the removable upper section 41 is a tubular peg 42 whlch 18 adapted to be recelved ln the open upper end 43 of the bottom sectlon 40.
Wlthln the above-descrlbed structure a plurallty of the ~' flat glass sheets 23 18 sultably contained for shipment or stor--I 20 age. As viewed in Flgs. 1 and 2, the incllned ~urfaces 30 of `-~ the support ralls 29 support the bottom edges of the glass sheets .
23 at an acute angle to the horizontal and the surfaces 32 sup-I port the sheets laterally, and since the inclined surfaces are i normal to each other9 they provide an L-shaped supporting struc-;; ture. Thus, the plurallty of sheets 23 contained on the rack 20 will be parallel and their edges will be aligned. The sheet sup-; porting surfaces 30 and 32 are provided with an appropriate cushioning material 44, such as cellular plastic which is resil-ient and nonabrasive, to protect the face of the innermost sheet and the bottom edges of the s~heets which rest thereagainst from damageO The cushionlng material 44 preferably has a tough flex-ible skln with a somewhat more reslllent core 80 as to withstand the wear imposed by the glass sheets 23, particularly, the wear imposed by their sharp edges.
In order to provide for a more stable lateral sheet supporting structure and yet permit tisassembly of the rack 20, one or more longitudinal bracing rails 45 is provided between and detachably connected to the faclng sides of the upstanding support members 31. Thus, as viewed ln F18B~ 2 and 4. each ln-wardly facing side of the members 31 is provided wlth a plurality of vertically spaced anchor elements 46 disposed ln opposed re-lation to each other wherein each element has a pair of bayonet slots 47. As illustrated ln Flg. 4, each end of the braclng rail 45 18 provided with a bearlng plate 48 which bears agalnst a cor-responding anchor element and which is provited with a pair of pro~ecting headed lugs 49 which are received in the bayonet slots 47 to form a quick disconnect yet rigid coupling.
The plural-ity of glass sheets 23 contained in the above-described structure is retained against the bottom inclined sup-porting surfaces 30 by the pair of vertically positionable top tie members 25. A tie member 25 is mounted between the front and ~ 20 rear corner posts 27 and 28 of each end member 21 and 22. Ac-;`~ cordingly, as viewed in Fig. 1, each tie member 25 comprises frontand rear tubular legs 50 and 51, respectively, of smaller size than the tubular corner posts 27 and 28 so that each leg may be telescoped within the corresponding front and rear corner posts.
; The legs 50 and 51 are Joined together by a rail 52 that extends downwardly and inwardly from the front leg 50 to the rear leg 51 80 that when the bar 25 is mounted on either end member 21 or 22, the glass contacting surface 53 of the rail 52 will be parallel to the bottom inclined glass supporting surface 30. The surface 53 is also provided with a pad of the cushioning material 44 to protect the top edges of the glass sheets against damage.
In order to retain each telescoped leg 50 and 51 at the desired extension relative to its corresponding corner post, two of its opposlte walls are perforated to provide a plurality of centrally arranged, spaced apertures 54. Thu~, the top ends of each corner post are~provided with a centrally posltloned aper-ture 55 with which the apertures 54 can be placed ln reglstry.
Th- leg- 50 or 51 ar- ret-lned ln th- corre~pondlng corner po-t-by a headed pln as prevlously described, that is, a pin 36 is inserted in registering apertures 54 and 55 of the legs and corner posts, re~pectlvely, and secured therein by a hairpin clip 38.
The glass sheets 23 are held against endwlse movement relative to the above-described structure by the restraining mem-bers 26 as illustrated in Flg. l. Thus, a~ vlewed in Fig. 2, each restraining member 27 18 formed ln the shape of a T and has an upstanding glass contacting sectlon 56 and a tubular leg 57.
The glass contactlng surface 58 is also provlded wlth a pad of the cushioning material 44 to protect the end edges of the glass sheets against damage. The leg 57 is tele~copically received within a horizontally extending tubular elemene 59 provided in the mid-portion of each of the sheet supporting rails 29 of the 20 end members 21 and 22. In order to retain each restralning mem-ber 26 at a desired extension relative to the rail 29, the ver-tically opposed walls of the leg 57 are perforated to form a plurality of centrally arranged, spaced apertures 60. Thus, the element 59 i8 provided with a centrally positioned aperture 61 with which any of apertures 60 can be placed in registry. The leg 57 of the restraining member 26 is retained in the element 58 by a headed pin 36 ' and hairpin clip 38 a8 previously described.
As viewed in Fig. 5, the rack 20 may be adapted to carry a plurality of groups or separate stacks 62, 62' and 62" of gla~s 30 sheets as illustrated in phantom lines. Acccrdingly 9 a rectangu-lar floor 63 of the desired size is placed on the end members 21 and 22 and its central portion is supported by a brace member 64.
The brace member 64 lncludes a transver~e rail element 65 having ~076073 .
a pin 66 dependlng from one end thereof for lnsertion in an aperture 67 (see Flg. 1) provided ln the side rall 24 and a grooved longitudinal element 68 depending from the other end thereof whlch surrounds the other side rail 24. An additlonal brace rail 45 is positloned adJacent the lower end of the glass ,~ unlts to prevent the lower end of the central glass unlt 62 ' ~ from moving transver6ely relatlve to the floor 63.
¦ To adapt the rack 20 for stacklng and handllng, a runner 69 extending between the correspondlng front and rear cor-¦ 10 ner posts 27 and 28 of each end member 21 and 22, is provided for supporting the rack 20 upon a floor with the lower ends of the corner posts spaced slightly above the supporting surface of the runner 69. The runner 69 is formed with a substantially flat center portion 70 and upwardly directed end portions 71 8ecured to the end rall 29 as well as to the corner posts. A vertlcally disposed reinforclng plate 72 18 secured between the runner 69 and the end rall 29 with sufficient space left between them to `, provide openings for the fork of a conventional lift truck.
-I To allow the racks 20 to be stacked upon one another, 20 there is provided in the top of each leg 50 and 51 of the tle member 25, a stacking peg 73 adapted to be received in the bottom of the eorner post of another similarly constructed rack. Each peg 73 has a wide base portion 74 which provides support for the corne~ posts stacked upon it.
'l Briefly describing the manner in which the rack may be used, for example, in transporting a single group of flat glass sheets 23 as illustrated in Flg. 1, a deslred number of sheets are placed on the L-shaped supporting surfaces of the rack 20 then the top tle members 25 and the end restraining members 26 30 are secured in position to bear agalnst the top edges and the end edges of the glass sheets 23, respectlvely. After the glass sheets have been secured as descrlbed, wedge-shaped elements 75 -- 8 -- -~
and 76 of cushioning material are placet between the inner face of the front corner posts 27 and the face of the outermoet sheet of glass at lts top ant bottom edges, respectively, to prevent outwsrd transverse mo~rement on the glass sheets.
In using the rack 20 to traneport multiple groups of glass sheets as illustrated in Flgs. 5 ant 6, a desiret number of sheets of glass are placed ln each group and on the floor 63.
Spacers 77 may be placed between the at~acent edges of the groups to prevent damage therebetween. The end groups 62 and 62" are restrained within the rack 20 as described above. In this case, however, a U-shaped tying member 78 havlng an inclined face 78 covered wlth cushioning m-terial, extends between the pair of front corner posts 27 ad~acent the top ends thereof so that the lncllned face bears against the face of the outermost sheet of glass of each group. The legs of the U-shaped tying member 78 engage the outwardly facing sides of the front corner posts 27 -.
to prevent spreading therebetween. A lip 79, secured to and e~c-;~ tendlng along the front edge of the floor 63, prevents outward,. . .
transverse movement of the lower edges of the glas~ sheets.

More specifically, each sheet supporting end member 21 or 22 comprises a front corner post 27 and a rear corner post 28 which are ~oined together by a horizontal bottom sheet support-ing rail 29. As best illustrated in Fig. 2, the sheet support-ing rail 29 extents between ant is rigidly connected as by weld-ing to the lower ends of the corner posts 27 and 28. The top surface 30 of the rail 29 slopes townwardly and inwardly at an acute angle to the horizontal from the front corner post 27 to the rear corner post 28 for supporting the bottom etges of the glass sheets 23 in an inclined position. Lateral support for the glass sheets 23 is provided by an upstanding sheet supporting mem-ber 31 which ex~ends perpendicularly upwardly from the sloping surface 30 of the rail 29 to the top end of the rear corner post .;
28. Thu~, the surface 32,of the upstanding member 31 provides an inclined lateral support against which the substantially upright surface of the innermost sheet of glass 23 rests when it is stand-ing o~ its bottom edge on the inclined surface 30 of the rail 29.
In order to provide for ease in assembling and disas-sembling and at the same time provide for a rugged rack assembly, each end of the side rails 24 is detachably connected to its ad-~acent corner post by a peg and socket device 33. Thus, as in-dicated in Fig. 2 and specifically illustrated in Fig. 3, the corner posts 27 and 28 of eacp end supporting member 21 and 22 are pro~ided with a horlzontally pro~ecting tubular peg 34 whereln the pegs pro~ecting from the end member 21 face the pegs pro~ectlng from the end member 22. Each peg 34 is adapted to be received ln an open end 35 of the slde ralls 24. Each end of the slde ralls 24 is locked to lts correspondlng peg 34 by a headed pin 36 whlch is placed through a set of registerlng aper-tures 37 provided in each end of the ralls 24 and the peg 34.
The pln 36 18 retalned ln place by a halrpln cllp 38. Also, each ent of the slde rails 24 is provlted wlth a dependlng angle-shaped bracket or gusset 39, a slde of whlch bears agalnst the correspondlng corner post to provlde a stable Jolnt structure.
As lllustrated ln Flg. l, the front corner post 27 may be formed of two separable lnterflttlng sections 80 that a sec-tion of each front post can be readlly removed ant replaced on the frame 80 as to permlt ready access for loadlng and unloading of the glass sheets 23 on the rack 20. Thus9 each front corner post 27 18 comprlset of a bottom section 40 and a removable upper sectlon 41. At the lower end of the removable upper section 41 is a tubular peg 42 whlch 18 adapted to be recelved ln the open upper end 43 of the bottom sectlon 40.
Wlthln the above-descrlbed structure a plurallty of the ~' flat glass sheets 23 18 sultably contained for shipment or stor--I 20 age. As viewed in Flgs. 1 and 2, the incllned ~urfaces 30 of `-~ the support ralls 29 support the bottom edges of the glass sheets .

In order to provide for a more stable lateral sheet supporting structure and yet permit tisassembly of the rack 20, one or more longitudinal bracing rails 45 is provided between and detachably connected to the faclng sides of the upstanding support members 31. Thus, as viewed ln F18B~ 2 and 4. each ln-wardly facing side of the members 31 is provided wlth a plurality of vertically spaced anchor elements 46 disposed ln opposed re-lation to each other wherein each element has a pair of bayonet slots 47. As illustrated ln Flg. 4, each end of the braclng rail 45 18 provided with a bearlng plate 48 which bears agalnst a cor-responding anchor element and which is provited with a pair of pro~ecting headed lugs 49 which are received in the bayonet slots 47 to form a quick disconnect yet rigid coupling.
The plural-ity of glass sheets 23 contained in the above-described structure is retained against the bottom inclined sup-porting surfaces 30 by the pair of vertically positionable top tie members 25. A tie member 25 is mounted between the front and ~ 20 rear corner posts 27 and 28 of each end member 21 and 22. Ac-;`~ cordingly, as viewed in Fig. 1, each tie member 25 comprises frontand rear tubular legs 50 and 51, respectively, of smaller size than the tubular corner posts 27 and 28 so that each leg may be telescoped within the corresponding front and rear corner posts.
; The legs 50 and 51 are Joined together by a rail 52 that extends downwardly and inwardly from the front leg 50 to the rear leg 51 80 that when the bar 25 is mounted on either end member 21 or 22, the glass contacting surface 53 of the rail 52 will be parallel to the bottom inclined glass supporting surface 30. The surface 53 is also provided with a pad of the cushioning material 44 to protect the top edges of the glass sheets against damage.
In order to retain each telescoped leg 50 and 51 at the desired extension relative to its corresponding corner post, two of its opposlte walls are perforated to provide a plurality of centrally arranged, spaced apertures 54. Thu~, the top ends of each corner post are~provided with a centrally posltloned aper-ture 55 with which the apertures 54 can be placed ln reglstry.
Th- leg- 50 or 51 ar- ret-lned ln th- corre~pondlng corner po-t-by a headed pln as prevlously described, that is, a pin 36 is inserted in registering apertures 54 and 55 of the legs and corner posts, re~pectlvely, and secured therein by a hairpin clip 38.
The glass sheets 23 are held against endwlse movement relative to the above-described structure by the restraining mem-bers 26 as illustrated in Flg. l. Thus, a~ vlewed in Fig. 2, each restraining member 27 18 formed ln the shape of a T and has an upstanding glass contacting sectlon 56 and a tubular leg 57.
The glass contactlng surface 58 is also provlded wlth a pad of the cushioning material 44 to protect the end edges of the glass sheets against damage. The leg 57 is tele~copically received within a horizontally extending tubular elemene 59 provided in the mid-portion of each of the sheet supporting rails 29 of the 20 end members 21 and 22. In order to retain each restralning mem-ber 26 at a desired extension relative to the rail 29, the ver-tically opposed walls of the leg 57 are perforated to form a plurality of centrally arranged, spaced apertures 60.

The leg 57 of the restraining member 26 is retained in the element 58 by a headed pin 36 ' and hairpin clip 38 a8 previously described.
As viewed in Fig. 5, the rack 20 may be adapted to carry a plurality of groups or separate stacks 62, 62' and 62" of gla~s 30 sheets as illustrated in phantom lines. Acccrdingly 9 a rectangu-lar floor 63 of the desired size is placed on the end members 21 and 22 and its central portion is supported by a brace member 64.
The brace member 64 lncludes a transver~e rail element 65 having ~076073 .
a pin 66 dependlng from one end thereof for lnsertion in an aperture 67 (see Flg. 1) provided ln the side rall 24 and a grooved longitudinal element 68 depending from the other end thereof whlch surrounds the other side rail 24. An additlonal brace rail 45 is positloned adJacent the lower end of the glass ,~ unlts to prevent the lower end of the central glass unlt 62 ' ~ from moving transver6ely relatlve to the floor 63.
¦ To adapt the rack 20 for stacklng and handllng, a runner 69 extending between the correspondlng front and rear cor-¦ 10 ner posts 27 and 28 of each end member 21 and 22, is provided for supporting the rack 20 upon a floor with the lower ends of the corner posts spaced slightly above the supporting surface of the runner 69. The runner 69 is formed with a substantially flat center portion 70 and upwardly directed end portions 71 8ecured to the end rall 29 as well as to the corner posts. A vertlcally disposed reinforclng plate 72 18 secured between the runner 69 and the end rall 29 with sufficient space left between them to `, provide openings for the fork of a conventional lift truck.
-I To allow the racks 20 to be stacked upon one another, 20 there is provided in the top of each leg 50 and 51 of the tle member 25, a stacking peg 73 adapted to be received in the bottom of the eorner post of another similarly constructed rack. Each peg 73 has a wide base portion 74 which provides support for the corne~ posts stacked upon it.
'l Briefly describing the manner in which the rack may be used, for example, in transporting a single group of flat glass sheets 23 as illustrated in Flg. 1, a deslred number of sheets are placed on the L-shaped supporting surfaces of the rack 20 then the top tle members 25 and the end restraining members 26 30 are secured in position to bear agalnst the top edges and the end edges of the glass sheets 23, respectlvely. After the glass sheets have been secured as descrlbed, wedge-shaped elements 75 -- 8 -- -~
and 76 of cushioning material are placet between the inner face of the front corner posts 27 and the face of the outermoet sheet of glass at lts top ant bottom edges, respectively, to prevent outwsrd transverse mo~rement on the glass sheets.
In using the rack 20 to traneport multiple groups of glass sheets as illustrated in Flgs. 5 ant 6, a desiret number of sheets of glass are placed ln each group and on the floor 63.
Spacers 77 may be placed between the at~acent edges of the groups to prevent damage therebetween. The end groups 62 and 62" are restrained within the rack 20 as described above. In this case, however, a U-shaped tying member 78 havlng an inclined face 78 covered wlth cushioning m-terial, extends between the pair of front corner posts 27 ad~acent the top ends thereof so that the lncllned face bears against the face of the outermost sheet of glass of each group. The legs of the U-shaped tying member 78 engage the outwardly facing sides of the front corner posts 27 -.
to prevent spreading therebetween. A lip 79, secured to and e~c-;~ tendlng along the front edge of the floor 63, prevents outward,. . .
transverse movement of the lower edges of the glas~ sheets.
