Definitions
- the present invention relates to a shelving system and wherein shelves are clampingly secured to corner posts by clamps which are latched and unlatched by a lever to provide a sturdy and easy-to-assemble shelf assembly
- shelf assemblies wherein a plurality of shelves are connectable to support posts.
- One major problem of such shelf assemblies is that they are difficult and time-consuming to assemble in order to secure a rigid connection of the shelf with the support posts. Often, a hammer or such other device is necessary in order to engage the connection of brackets with the support posts. Being difficult to assemble, they are also difficult to disassemble, if additional shelves need to be added to a shelf assembly. Most of the shelves are connected to the post by sliding corner connectors from the top of the posts and therealong. Usually, if a shelf is to be added, the other shelves need to be displaced to provide a different shelf spacing.
- shelf assemblies of the above-described type A still further problem with shelf assemblies of the above-described type is that during assembly of the shelving to the post it is often necessary to lay at least two posts on the floor surface and hold the shelves vertically thereover to effect the connections. Once all the shelves have been connected to two of these posts, then the other two posts are laid on the floor and the semi-assembled assembly is then placed over those two posts wherein the connectors have to be engaged at corresponding spacings to the already engaged two posts. This creates misalignment of shelves and waste of time in assembling and disassembling the shelf assembly in order to obtain proper alignment of the shelves with the posts. Skilled personnel is usually required to assemble these shelf assemblies. Still further, some of the shelf assemblies are not aesthetically pleasing to the eye due to the construction of the support posts and the clamping devices.
- Another feature of the present invention is to provide a shelving system which is easy to assemble and which provides a secure clamping connection of the shelves to the support posts.
- Another feature of the present invention is to provide a shelving system wherein the shelves are easy to assemble and disassemble from the posts and wherein additional shelves can be added by easily displacing already assembled shelves in a simple, effective and quick manner.
- Another feature of the present invention is to provide a shelving system which can be assembled with the post disposed vertically and the shelves connected horizontally and without the use of tools and by a non-expert person.
- the present invention provides a shelving system which comprises one or more shelves of rectangular outline.
- Each shelf has an open-ended post receiving channel in each corner thereof.

Description
- The present invention relates to a shelving system and wherein shelves are clampingly secured to corner posts by clamps which are latched and unlatched by a lever to provide a sturdy and easy-to-assemble shelf assembly
- Various shelf assemblies are known wherein a plurality of shelves are connectable to support posts. One major problem of such shelf assemblies is that they are difficult and time-consuming to assemble in order to secure a rigid connection of the shelf with the support posts. Often, a hammer or such other device is necessary in order to engage the connection of brackets with the support posts. Being difficult to assemble, they are also difficult to disassemble, if additional shelves need to be added to a shelf assembly. Most of the shelves are connected to the post by sliding corner connectors from the top of the posts and therealong. Usually, if a shelf is to be added, the other shelves need to be displaced to provide a different shelf spacing.
- A still further problem with shelf assemblies of the above-described type is that during assembly of the shelving to the post it is often necessary to lay at least two posts on the floor surface and hold the shelves vertically thereover to effect the connections. Once all the shelves have been connected to two of these posts, then the other two posts are laid on the floor and the semi-assembled assembly is then placed over those two posts wherein the connectors have to be engaged at corresponding spacings to the already engaged two posts. This creates misalignment of shelves and waste of time in assembling and disassembling the shelf assembly in order to obtain proper alignment of the shelves with the posts. Skilled personnel is usually required to assemble these shelf assemblies. Still further, some of the shelf assemblies are not aesthetically pleasing to the eye due to the construction of the support posts and the clamping devices.
- It is therefore a feature of the present invention to provide a shelving system which substantially overcomes the above-mentioned disadvantages of the prior art.
- Another feature of the present invention is to provide a shelving system which is easy to assemble and which provides a secure clamping connection of the shelves to the support posts.
- Another feature of the present invention is to provide a shelving system wherein the shelves are easy to assemble and disassemble from the posts and wherein additional shelves can be added by easily displacing already assembled shelves in a simple, effective and quick manner.
- Another feature of the present invention is to provide a shelving system which can be assembled with the post disposed vertically and the shelves connected horizontally and without the use of tools and by a non-expert person.
- According to the above features, from a broad aspect, the present invention provides a shelving system which comprises one or more shelves of rectangular outline. Each shelf has an open-ended post receiving channel in each corner thereof. The post receiving channel is transversely oriented with respect to a shelf support surface of the shelf and has a vertical opening facing inwardly of the shelf. The channel is shaped to receive a support post in close fit therethrough with an inner wall portion of the support post facing the vertical opening. The inner wall has spaced-apart arresting formations on an outer surface thereof. A clamp having a clamping means is provided with one or more connecting formations for interlocking with the arresting formations. A latch is provided for urging the connecting formations against the inner wall portion of the support post with the one or more connecting formations in engagement with one or more of the arresting formations. The latch maintains a constant locking pressure against the clamping means to immovably secure the shelf to the support post at a desired position.

FIG. 7 , there is shown generally at 10 a shelf assembly which comprises one ormore shelves 11 of rectangular outline and secured to fourcorner support posts 12. The present invention concerns theclamp assemblies 13 which secure theshelves 11 to the corner support posts and for ease of illustration the drawings only show a corner portion of the shelves together with their clamp assemblies. It is noted that aclamp assembly 13 is provided in all four corners of a shelf. - With reference now to
FIGS. 1 and 2 , there is shown aclamp assembly 13 connected to acorner support post 12. As hereinshown, eachshelf 11 has an open-endedpost receiving channel 14 secured in each corner thereof by welding. The shelf as hereinshown is a wire-rod shelf having a plurality ofhorizontal wires 15 spot-welded to transverse reinforcedtransverse ribs 16, also formed of wires welded together. Accordingly, thepost receiving channel 14 is welded to some of these steel rods. As illustrated, thepost-receiving channel 14 is transversely oriented with respect to thesupport surface 17 of theshelf 11. Thepost receiving channel 14 also has avertical opening 18 as better seen fromFIG. 2 , which faces inwardly of the shelf. Thepost receiving channel 14 also has a transverse cross-section which is configured for receiving thesupport post 12 in close fit therethrough. - As hereinshown, the
support post 12 has an oval-like cross-section which defines opposedparallel side walls 19 andconvex end walls Arresting formations 21, in the form of transverse notch depressions, are formed at the apex of the innerconvex end wall 20. The support post is also fabricated of steel. - As illustrated, when the
support post 12 is received within thepost receiving channel 14, an inner wall portion of theend wall 20 of the post projects outwards of thevertical opening 18. Theclamp assembly 13 is provided with aclamping jaw 22 which is provided on an inner surface thereof with connectingformations 23 as shown inFIG. 3 for interlocking with the arrestingformations 21. Accordingly, the connectingformations 23 have the same spacing as the arrestingformations 21. - The
clamping jaw 22 is connected to alatch 24 which urges theclamping jaw 22 against theconvex end wall 20 of the support post with the connecting formations in engagement with the arresting formations. This latch 234, when in a closed or engaged position, as shown inFIG. 1 , maintains a constant locking pressure against theclamping jaw 22 to immovably secure theshelf 11 to thesupport post 12 at a desired position therealong. - As hereinshown, the
latch 24 is provided with apivotal arm 25 whereby to engage and disengage the connectingformations 23 from the arrestingformations 21 and hence disconnecting theclamping jaw 22 from thesupport post 12. The clamping jaw has a concave shape to embrace theconvex end wall 20 of the support posts. As shown in the embodiments ofFIGS. 1 and 2 , the latch and clampingjaw 22 are removably secured to the shelf and the post. - The
pivotal arm 25 is pivotally secured at one end thereof to anend pivot connection 26 secured to a projectingrib 27 welded to the clampingjaw 22. A bracingarm 28 is pivotally connected to thepivotal arm 25 at afurther pivot connection 29 spaced from theend pivot connection 26. The bracingarm 23 has a shelf-engaging end constituted by aU-shaped notch 30 formed in thefree end 31 of the bracing arm and dimensioned to receive a wire rod, hereinwire rod 32 of the shelf thereacross. When the latch is in the engaged position, as shown inFIG. 1 , the bracing arm is in alignment with the connectingrib 27 and theend pivot connection 26 andfurther pivot connection 29 are in horizontal alignment. The bracingarm 28 is also dimensioned whereby to apply this constant pressure and is therefore positioned to apply a constant force against the clampingjaw 22 when disposed in disalignment. In order to disconnect the latch, it is simply necessary to lift the pivotal arm, as shown inFIG. 2 , to remove the clamping pressure. - As hereinshown, the clamping
jaw 22 is also provided withguide ribs 33 which maintain the clamping jaw in alignment in that these guide ribs are disposed on opposed sides of wire rods, hereinwire rod 34. - As is also illustrated in
FIG. 2 , thepivotal arm 25 is provided with a flexible retention means in the form of aspring clip 35 which is shaped to snappingly engage a wire rod, hereinwire rod 36 when the arm is urged to an engaging position, as shown inFIG. 1 . - With reference now to FIGS. 3 to 6, there is shown another embodiment of the construction of the
latch 24 and herein designated byreference numeral 24′. Thelatch 24′ is separate from the clampingjaw 22″. As hereinshown, thepost receiving channel 14′ is also of U-shaped cross-section and defines postparallel side walls concave end wall 41. The clampingjaw 22′ is formed as a concave clamping wall, similar to that illustrated inFIGS. 1 and 2 and is provided with the one or more connectingformations 23. The side walls of the clamping jaws are provided with outer projecting tabs 42 which are received inrespective guide slots 43 formed in theparallel side walls post receiving channel 14′. Accordingly, the clampingjaw 22 is movably connected to the post receiving channel. - The

When thearm 25′ is displaced to a shelf engaging position, as shown inFIG. 4 , the cam applies a clamping force against the clampingjaw 22′ as thereinshown. Theclamp 24′ is further provided with aU-shaped cavity 46 under thepivotal arm 25′ adjacent thecam formation 45 for snap engagement with a wire rod, hereinwire rod 47 of theshelf 11 and thiswire rod 47 constitutes a pivot connection. As hereinshown, when the latch is in the engaged position (seeFIG. 4 ) thepivotal arm 25 lies below thesupport surface 17 of theshelf 11 to prevent accidental disengagement of the latch by goods placed on the shelf. As hereinshown, the clampingjaw 22″ is dimensioned to fit between the opposed side 2alls 40 and 40′ of thepost receiving channel 14′ in an unobstructive manner to permit theconcave surface 48 of the clamping jaw to embrace theconvex end wall 20 of thesupport post 12. - As shown in
FIGS. 1 and 2 ,post receiving channel 12 is provided with outwardly sloping end edges 12″ and the clamping jaw has aconcave clamping surface 39 having opposed inner wall end portions disposed for sliding displacement on the outwardly sloping end edges 12″ when urged thereon by thelatch 24. - Referring now more specifically to
FIGS. 8, 9 and 10, there is shown a further modification of the clamp. As hereinshown, theclamp assembly 50 is comprised of aflat clamp plate 51 which is provided with a projectingtab 52 in a rear face 53 thereof whereby to receive apivot pin 54 secured to afree end 55 of thepivotal arm 56 thereof. Thepivotal arm 56 has a connectingpivotal sleeve 57 secured transversely thereof whereby to secure thepivotal arm 56 to atransverse wire rod 58 of thewire shelf 60. The pivotal arm has an offsetintermediate section 59 to locate thefree end 61 closely spaced below the upper surface of thewire shelf 60. - As can be seen from
FIG. 9 , theflat clamping plate 51 has a flat end wall or clampingface 62 which is provided with one or more of the connecting formations, hereinformation 63 for interlocking with the arrestingformations 21 formed in thesupport post 12. By depressing thefree end 61 of thepivotal arm 56 in the direction ofarrow 64, the clampingplate 51 is retracted from its engagement with thesupport post 12. This permits thesupport post 12 to be displaced within the open-ended post receiving channel formed in each corner of thewire shelf 60. - As hereinshown, the open-ended
post receiving channel 70 is constituted by a pair of parallel spacedwire rods wire shelf 60 whereby to receive thesupport post 12 in close fit therein. The twowire rods wire rod section 72 and define opposed parallel side wire sections, one side wire section denoted byreference numeral reference numeral 71″ and 71′″. The wires also define a concaveend wire section 73 and shaped for close fit about thecurved edge wall 12′ of the support post. The clampingplate 51 may also be provided with notches 74 and 74′ to loosely receive thewire rods - Referring now to
FIG. 9 , the post receiving channel is similar to that as illustrated in FIGS. 3 to 6 and wherein the post receiving channel is a U-shaped clamp secured to the corners of the shelf by welding. The channel has opposedparallel side walls FIG. 10 and aconcave end wall 81. As better illustrated from the exploded view ofFIG. 10 , the clampingplate 51 is provided with outer projectingtabs 82 in opposed side edges 83 thereof. These projecting tabs are received inrespective guide slots 84 provided in theparallel side walls plate 51 from an engaged to a disengaged position by the actuation of thepivotal arm 56. Theguide slots 54 are curved or angulated guide slots to guide the displacement of theflat clamp plate 51. - It can readily be seen that with the shelving system as described herein, shelves are easily connected and disconnected from the
support post 12. To construct a shelf assembly as shown inFIG. 7 , it is merely necessary to first dispose the post within thepost-receiving channels 14 and each of the corners of the shelf and to engage the clamping jaw at a desired position with respect to the arrestingformations 21. Although not illustrated, numbers can be disposed or stamped in theside walls 19 of the connecting posts adjacent these arresting formations. If these formations are spaced apart one inch then one inch interval markings would appear therein whereby to make it easy to connect the shelves to the posts whereby the shelves are perfectly parallel to one another between the posts. To connect the shelf, it is merely necessary to engage the latches. Additional shelves are positioned from the top of the posts and secured at a desired elevation with respect thereto. If it is necessary to add more shelves after an assembly has been in use, then one needs to merely displace some or all of the shelves already assembled and thereafter to introduce a new shelf from the top end of the post. This is easily accomplished with this latching system. To disassemble a shelving system, the shelves are easily disconnected from the post and they can be removed one at a time from the top end. On the other hand, the shelves could be disengaged from the bottom end and just slid down the post one on top of each other. With all of the latches in the disengaged position, the post can then be pulled out with the shelves stock-piled one on top of the other. Accordingly, this system is easy to assemble and disassemble and does not require extra tools or skilled personnel in order to fabricate a shelving system utilizing the present invention. - Referring now to FIGS. 11 to 14, there is shown a further embodiment of the
clamp 90 and as hereinshown the clamp has alatch section 91 having ahook end 92 for securing at its free end a clamping means, herein constituted by a wirerod clamping member 93.

The opposedstraight wire sections FIG. 11 , thehook end 92 of thelatch 91 is secured about this connecting transversestraight wire section 95. - The
latch 91 is also a wire-rod latch formed of a single wire rod bent in two sections to provide a pair of closely spaced equallength wire rods hook hook end 92. Thelatch 91 has a clampingformation 99 for engaging a transverse edge of the shelf which is spaced forwardly of the vertical opening and herein constituted by thetransverse wire rod 36. - The clamping
formation 99 is constituted by an upward bend in thelatch rods rod clamping member 93. This upward bend merges into a substantiallytransverse handle formation 100 integrally formed therewith and at the opposed end of the latch. The predetermined distance of the upward bend from the clampingmember 93 is calculated in relation to the distance between theinner wall portion 20 of thesupport post 12 and thetransverse wire rod 36 whereby anouter face 101, seeFIG. 13 , of the bend or clampingformation 99 can be clamped under pressure over aforward face 102 of thetransverse wire rod 36 by applying a downward pressure against thehandle formation 100 in the direction ofarrow 102, as shown inFIG. 13 , to pressure clamp the connectingformations 96 and 96 i into the arrestingformations 21 as shown inFIG. 14 . As shown inFIGS. 13 and 14 , the distance of theintermediate rod sections 91 is such that when the connectingformations formations 21, thecurved section 104 of thewire rods formation 99 rests against thetransverse wire rod 36, as better shown inFIG. 13 and by applying the downward clamping pressure in the direction ofarrow 102 this urges thelatch 91 downward into the top surface of theshelf 11 and clamps under pressure the connecting formations into the arrestingformations 21 with this pressure remaining applied due to the rigidity of the steel wire rods. As can be seen inFIG. 14 with the clamp in engagement, thehandle portion 100 lies within the surface of the shelf thereby providing no obstruction. It is also easy to disengage the clamp by simply engaging thefree end 105 of the clamp and lifting it out of engagement with thetransverse wire rod 36. - With reference now to
FIGS. 15 and 16 , there is shown a further embodiment of the wire rod clamping member and herein constituted by a rectangularwire rod member 110. The wire rod member is formed by a wire rod which is bent to form opposed parallel horizontal wire sections 111 and 111′ and opposed parallelvertical wire sections formations 21 of the support posts 12, as previously described. - The rectangular
wire rod member 110 is secured to thewire rod latch 100 as previously described with reference to FIGS. 11 to 14 but wherein thewire rods flat connection shoe wire rod sections - It is within the ambit of the present invention to cover any obvious modifications of the preferred embodiment described herein. Although the shelves as hereinshown are illustrated as wire rod shelves, it is to be understood that the shelves could be fabricated from plastic materials or they may have a solid support surface. Other obvious modifications become apparent to a personnel skilled in the art from a reading of the present specification.
