The specific embodiment

Referring now to accompanying drawing and illustrative embodiment; Anchor fitting 10 can attach to an end of collapsible transportation shelf or container 12 or the outside of sidewall; Each anchor fitting 10 can be connected to the adjacent anchor fitting 10 of transportation shelf 12 (the transportation shelf that for example stack at the first transportation shelf top), for example shown in Fig. 2-4.As the transportation shelf 12 ' (Fig. 1) of prior art; Transportation shelf 12 can stack at the top each other; So that with the processing of the shelf that stack structure and effectively storage, for example be folded storage when shelf or container, and/or when the three unities is transported to another place.Anchor fitting can be used for making the transportation shelf that stack fixed to one another, and a kind of clearly visual indication is provided when device is fixed, even be that fix and safety and can move so that user and operator also can easily confirm folded shelf a long way off.

Collapsible transportation shelf 12 are normally rectangular, have distolateral 13 with the lengthening side 15 (Fig. 1), it has removable or the detouchable wall.Transportation shelf 12 can comprise the traditional interconnects that is positioned at shelf 12 folding corner regions 14.This interconnects comprises 16 upwardly extending public extension or the post (not shown)s from upper corner zone, and is arranged to female receptacle or the cover relative with upper corner zone 16, is used to admit the post of adjacent shelf.Corresponding female portion of transportation shelf 12a, the degree of freedom that the transportation shelf that the transportation shelf that assurance stacks are aimed at and restriction stacks move are each other aimed at and be received in to the public post that transports shelf 12b down.Each anchor fitting 10 all attaches to or is arranged on (for example upper and

lower transportation shelf

12a, 12b) on the transportation shelf separately; And can attach on the part of respective fixation device of adjacent transportation shelf, so that through restriction or stop basically or prevent that adjacent transportation shelf break away from

adjacent shelf

12a, 12b together fixed to one another each other.Obviously; Anchor fitting 10 can replace the locking ability of traditional interconnects; Its allusion quotation shape characteristic is like transportation shelf 12 stable and alignment function to be provided for the article that stack; But other aligning/invariant feature for example meshes breach, magnet etc. and also can be used to the article that stack and provide and aim at and stable, the article that wherein stack can be as in illustrated example a top that is arranged on another, perhaps be arranged side by side.

Anchor fitting 10 comprises support element 18, last bolt 20, following bolt 22 and tethers or tethers member 24.In the embodiment that Fig. 2-7 describes; Support element 18 is roughly U-shaped or tunnel-shaped; And comprise a pair of almost parallel and outwards outstanding left and

right arm

26a, 26b; They are from bottom 28 vertical extent of cardinal principle U-shaped structure, between

arm

26a, 26b, confirm the passage 30 of capwise substantially when respectively transporting shelf when support element 18 attaches to.Last bolt 20 and following bolt 22 all pass two arm 26a, the 26b of passage 30 and splice holder element 18.Just as will be discussed later in detail, tethers 24 first end 24a place couple anchor fitting on bolt 20, locate removably to be connected to the following bolt 22 of another anchor fitting of adjacent transportation shelf at the second end 24b (24a is relative with first end).When not engaging the following bolt 22 of adjacent fixed device, tethers 24 hangs between the arm 26a that is hung in the vertical channel 30, the 26b, shown in ' A ' among Fig. 2-5 from last bolt 20.When being coupled to anchor fitting 10, tethers 24 (promptly is coupled to the anchor fitting of transportation shelf 12a; It directly places on the following transportation shelf 12b of attached tethers 24) the following bolt 22 of support element 18 time; Tethers 24 extends upward from the last bolt 20 of the support element 18 that transports commodity price 12b down, crosses between each vertical channel 30 of adjacent supports member 18 (like support element and the tethers (locating at ' B ') referring to the following transportation shelf 12b in Fig. 2-4 and 6).Therefore, tethers 24 can be connected to the last bolt 20 of the support element that descends to transport shelf 12b 18 the following bolt 22 of the support element 18 of transportation shelf 12a, can prevent that

adjacent transportation shelf

12a, 12b from separating.

Referring to Fig. 4, in the embodiment shown, each shelf comprises a pair of anchor fitting 10 on each distolateral 13 (only having represented one distolateral 13 among Fig. 4) that is arranged on shelf 12, so that each shelf 12 all comprises four anchor fittings 10 altogether.Each anchor fitting 10 is close to or arranges near independent folding corner region 14.Anchor fitting also can adopt other number and layout.For example, a pair of anchor fitting 10 can add or be arranged on alternatively each lengthening side 15 (see figure 1), perhaps has only single anchor fitting 10 can be arranged on a side or many sides of shelf 12.Obviously, although among the embodiment that has described open and describe relate to two collapsible transportation shelf that stack, the present invention also can be used in the plural collapsible transportation shelf that stack.For example; Each shelf in a plurality of collapsible transportation shelf that folded and stacked; As shown in Figure 1; Can be provided with the anchor fitting 10 that the anchor fitting 10 of the transportation shelf of one or more and adjacent one another is aimed at, thus can make each folding transportation shelf be fixed on above and/or under on those transportation shelf of adjacent one another.For example shown in Figure 4; With respect to anchor fitting 10; Anchor fitting can add and comprise retainer or chain retainer 31, is used for when tethers 24 is not connected to the anchor fitting 10 of adjacent transportation shelf, helping to keep tethers 24 in place, for example is used for the anchor fitting 10 of the transportation shelf 12a of Fig. 4.Retainer 31 can comprise the arm 26a at support element 18, bolt or the bar between the 26b; So that each tethers 24 is positioned at after the chain retainer 31; Thereby be in unused state and transportation shelf 12 when moving at tethers 24, prevent that tethers 24 from outwards waving from anchor fitting 10.Retainer 31 for example can comprise the steel pole that diameter is about 1/4 to 3/8 inch; Its welding or be fixed on each arm 26 with other modes; Also can be along the length setting of support element 18, when constituting chains with convenient tethers 24, the chain link of retainer 31 contact chains 24; It has the planar orientation that is approximately perpendicular to arm 26, shown in the transportation shelf 12a of Fig. 4.

Support element 18 is 28 welding or otherwise fastening or be fixed on shelf 12 in the bottom; And be included in the top through hole 32 among each arm 26a, the 26b; Through hole 32 basic alignings each other in top are used for will going up bolt 20 with the vertical direction of cardinal principle and are installed on arm 26a, 26b.Last bolt 20 can or adopt fastener etc. to be fixedly mounted in the top through hole 32 of

arm

26a, 26b through welding, can be inserted through the first end or the anchor portion 24a of tethers 24, so that tethers is fixed or basically for good and all is couple on the support element 18.

Arm

26a, 26b also define each other the left side of aligning and right lower quadrant through

hole

34a, 34b basically, so that support bolt 22 down with respect to

arm

26a, 26b with the direction of approximate vertical.Lower through-

hole

34a, 34b can be less times greater than the diameters of following bolt 22.Described in the embodiment that describes, the lower left quarter through hole 34a in the left arm 26a comprises at least one breach 36, is used for removably fixing therein bolt 22 down, and this also will describe below.Alternatively, through

hole

34a, 34b can comprise a plurality of breach, so that bolt 22 can remove from support element 18 fully down.Support element 18 can be used and transport shelf 12 essentially identical material; For example steel or other have the material of sufficient intensity, can or adopt fastener or other to couple or connecting method couples and be attached to the outside face of each transportation shelf 12 through welding.In addition, each can directly be soldered to a side or the end wall of the transportation shelf that are provided with at interval a pair of plate that separates that not is not bound up each other by bottom (for example bottom 28), so that form the support element in the scope of the invention.

Tethers 24 is flexible and the high member of intensity basically, has the ring that is used for being connected respectively bolt 20 and following bolt 22 at first end 24a and the second end 24b place.For example, as illustrated, tethers 24 can comprise a chain; For example a traditional chain has a plurality of chain links, for example 3/4 inch 80 grades chain; Can be purchased from the McMaster-Carr supplier company in Atlanta, Georgia State city, component part NO. is 3587T18.But obviously, the tethers of various other type shapes also is applicable to the present invention.For example, the cable (for example wirerope etc.) that is formed with ring at any end has equivalent action.Alternatively, also can add the special characteristic that couples, for example collude or fish plate (below will describe), perhaps be used for tethers is coupled to other connecting device of support element 18 with reference to Fig. 8-10 in any one or both ends of tethers 24.

Alternatively, the place of flexible tethers obviously can use the supreme bolt 20 of rigidity or solid element or element pivotal mounting and be coupled to down bolt 22.Therefore, the last bolt of any support element that can be coupled in down transportation shelf 12b and cable, chain or the rigid member gone up between the following bolt of the support element that transports shelf 12a all are suitable.The length that can select tethers is so that fixed to one another with upper and lower transportation shelf; And restriction perhaps prevents their (for example transportation shelf leave the perpendicular movement that another transports shelf) separated from one another basically; So that restriction or forbid basically or prevent that post 14 breaks away from the cover 16 of the transportation shelf 12 that stack when tethers is installed between adjacent or the shelf that stack fully; Thereby strengthen the stability of a plurality of transportation shelf that stack, and prevent to transport shelf accidental separation each other.Obviously, just passable as long as the transportation shelf can keep closely arranging complete lax permission that exists in the tethers when attached to a certain degree, so that post 14 remains in the cover 16, the maintenance shelf align.

Preferably as shown in Figure 7, following bolt 22 comprises axle 21, and this axle has close end 22a, middle part 22b and distal portion 22c.Handle portion or extension 38 extend perpendicular to close end 22a substantially, provide to be convenient to install and dismantle the gripping surface of bolt 22 down from the lower through-hole 34 of support element 18.The weight of handle portion 38 also is used to make down bolt 22 owing to gravity is partial to the direction of expectation, and this will describe below.The middle part 22b and the distal portion 22c of following bolt 22 have constant diameter, and distal portion 22c comprises the radially protrusion 40 of size corresponding to the breach 36 in the lower through-hole 34 simultaneously.Protrusion 40 extends from axle 21 with handle portion 38 identical radial direction at the homonymy of handle portion 38 or edge, so that handle portion 38 all extends upward from axle 21 with protrusion 40, protrusion 40 radially is inserted through the breach 36 in the lower through-hole 34.

After protrusion 40 passes breach 36 and is positioned at the left arm 26a outside of bolt 22 distal portion 22c under the support; Following bolt 22 rotates about 180 degree; For example by handle portion 38; So that radially protrusion 40 and handle portion 38 are to extending below, make protrusion 40 and breach 36 mal-alignmentes, bolt 22 disengaging lower through-hole 34 were down also forbidden in restriction basically when bolt was positioned at this direction instantly.The weight of handle portion 38 departs from bolt 22 and holds it in out-of-alignment direction; Thereby prevent radially protrusion 40 chances or accident alignment notch 36 again; So that following bolt 22 can not break away from support element 18, only if down bolt 22 is manually turned about 180 degree and makes radially protrusion 40 alignment notch 36 once more.Through descending bolt 22 to insert the opening on the second end 24b or encircling in 41; The second end 24b of tethers 24 removably is coupled to down bolt 22; Be positioned at vertical channel 30; And further will descend the distal portion 22b of bolt 22 and radially protrusion 40 be inserted through lower through-hole 34b, rotation is bolt and this bolt-lock is fixed on the appropriate location down, thereby prevents that this tethers breaks away from.Although protrusion 40 is represented as from axle 21 along handle portion 38 identical radial direction and stretches out; But bolt also can be configured to make handle portion to rely on the gravity rotation; Make an axle rotation protrusion be in and breach 36 out-of-alignment directions, and protrusion not the edge radial direction identical with handle extend from axle.

Referring now to Fig. 7 A and 7B,, shown optional following bolt 222 has and is arranged on the elastic component 223 of axle around 221.Instantly bolt 222 is installed in 18 last times of support, and elastic component 223 is between the outside of T-handle shown in the present embodiment 238 and arm 26b, so that elastic component 223 makes down bolt 222 be offset to open or unengaged position.Pass through hole 34 against elastic component 223 and rotate bolt 222 down through the radially protrusion 240 that promotes bolt 222 when protrusion 240 alignment notch 36 radially, feasible radially protrusion 240 is not aimed at the breach 36 of through hole 34, thereby can realize down the joint of bolt 222.When bolt 222 was not in place down, because T-handle 238 will be outstanding away from arm 26b, elastic component 223 provided additional safety factor.Fig. 7 A also discloses optional locking plate 225a, the 225b on arm 26b, be arranged on the through hole 34 that protrusion 240 passes breach 36 around.Locking plate 225a, 225b form the triangle wedge in said embodiment; Prevent protrusion 240 because the unintentional rotation of bolt 222 and alignment notch 36 down; Because protrusion 240 will be met locking plate 225a or 225b; Only if following bolt 222 at first further heads on the elastic force of elastic component 223 and extends, so that protrusion 240 leaves locking plate 225a and 225b during bolt 222 rotates down.Shown in Fig. 7 B, can be used for the stop member of elastic component 223 through being welded on retaining washer or retainer 227 on the axle 221.

Therefore, the invention provides the anchor fitting that is positioned on the transportation shelf of being arranged to stack arrangement, wherein anchor fitting comprises chain or tethers, in that the time spent is not placed in the vertical channel of shelf.Tethers is removable so that extend upward from the support that transports shelf down; At least part is received in the support of transportation shelf; Wherein tethers removably is coupled to the following bolt of the support of transportation shelf 12a, thereby provides shelf to be locked in the indication of vision clearly together with tethers across the mode between the overhead transportation shelf at interval each other.The following bolt of each support is a detouchable, so that the transportation shelf below being positioned at removably are coupled to the tethers of support.Following bolt can have radially protrusion or pin, is used to prevent down the unexpected or accidental disengaging of bolt.Through restriction or prevent the perpendicular movement between the adjacent transportation shelf, anchor fitting can with the post and cover collaborative work on the shelf, keep shelf safety, fixing, and can not be in alignment with each other dividually, for example be used to transport the depositing of shelf, lifting and transportation.

Alternatively, and referring to Fig. 8-10, another shown anchor fitting 110 is used to transport shelf 112a, and 112b is last, and that transportation shelf 112a, 112b have is distolateral 113, folding corner region 114 and upper corner zone 116.Anchor fitting 110 comprises the support element 118 that supports last bolt 120 and following bolt 122.As the support element 18 of anchor fitting 10, support element 118 comprises from welding or is fixed in bottom 128 outward extending a pair of arm 126a, the 126b of each transportation shelf 112 (for example passing through spacerarm 129).Each end of tethers 124 (for example chain or cable etc.) all comprises fish plate 142, is used for engaging with each upper and lower bolt 120,122 through the hole 141 in the plate 142.Except arm 126, support element 118 comprises also that in the upper end U-shaped side extension 144 is used for bolt 120 on the support section.

Each arm 126 defines top through hole 132 and lower through-hole 134.Be similar to the last bolt 20 and top through hole 32 of anchor fitting 10, following bolt 122 can be soldered or be permanently affixed in the lower through-hole 134 of arm 126a, 126b, so that the first end 124a of tethers 124 forever is coupled to load-carrying element 118.Be similar to the following bolt 22 and lower through-

hole

34a, 34b of anchor fitting 10; The last bolt 120 of anchor fitting 110 and at least one top through hole 132a, 132b can correspondingly configured (for example through being provided with breach 136 and corresponding formation protrusion 140 on last bolt) in upper right quarter through hole 132b; So that bolt is slidably engaged in top through hole 132a, the 132b in the permission; The distal portion 120c that prevents bolt 120 simultaneously breaks away from the passage 130 that support arm 126a, 126b limit, for example with the following bolt 22 and lower through-hole 34a, the similar mode of 34b of said fixing device 10.Should be understood that in Fig. 8 and 9, the second end 124b is attached at the upwardly extending tethers 124 of going up of shelf 112a, the fish plate 142 of its first end 124a will be permanently affixed at (not shown) on the 3rd transportation shelf that overlay shelf 112a top.

Last bolt 120 comprises handle extension 138, and this handle extension 138 is positioned at passage 130 outsides, but in the passage 146 that L shaped side extension 144 is confirmed, is for example illustrated by Fig. 9 and 10 the bests.Be similar to handle extension 38 and protrusion 40 radially; Last bolt 120 comprises the handle extension 138 of the middle part 120b that is in bolt 120; It aims at radially protrusion 140 basically, thereby prevents that the distal portion 120c of bolt 120 breaks away from the first end 124a (for example at fish plate 142 places) of passage 130 and tethers 124.U-shaped side extension 144 comprises the through hole 148 of the close end 120a that is used to support bolt, and close end is relative with distal portion 120c.Therefore, last bolt 120 can slide in top through hole 132a, 132b and in the through hole 148 of U-shaped side extension 144, thereby the second end 124b of tethers 124 removably is coupled to support element 118.

In order fixedly to couple or engage the transportation shelf that top of each other stacks, the at first rotation at first rotation of last bolt 120 quilts of the support element of transportation shelf down, part breaks away from vertical channel 130 at least then.The second end 124b of tethers 124 (the optional fish plate 142 that comprises) then is positioned; So that the distal portion 120c of bolt 120 on the ring in tethers or the fish plate or chain link or the through-hole alignment; Last bolt slides back on the position (the second end 124b that engages tethers 124) and is rotated, so that prevent the unexpected disengaging of bolt.Bolt can comprise two opposite radially protrusions, or the protrusion that is provided with of alternate manner, and for example through

hole

132b and 141 such through holes must need the cooresponding breach that protrusion radially passes.

In Fig. 8-10 illustrated embodiment; Because tethers 124 forever is coupled to down bolt 122; So the second end 124b of tethers dangles downwards from following bolt 122 naturally, near the last bolt 120 of support element with near the transportation shelf 112b under it, even when tethers 124 does not couple bolt 120.Fish plate 142 is to be roughly rectangular metal sheet; Have size and be fit to admit the through hole of going up bolt 120; Fish plate 142 can be used for eliminating that tethers 124 appears to couple bolt 120 and the danger that in fact do not couple, because can confirm fish plate 142 sizes so that they tend to be positioned at basically vertical channel 130 outsides during bolt 120 on not coupling.

Alternatively; The tethers 124 that does not couple for further elimination and the illusion of bolt occurs being coupled to seemingly; Hope that the distal portion 124b of any tethers that does not couple 124 is coupled to the last bolt 120 of same supports; For example among Fig. 8 and 10 shown in ' C ', thereby prevent that the tethers that does not couple from dangling or wave and produce the illusion of the support that is coupled to following transportation shelf downwards.Be fixed to the detachable of same supports through the second end 124b with untapped tethers 124 and go up on the bolt 120, tethers 124 also prevents contact or pulls stayed surface, for example when tethers is coupled to the shelf of transportation bottom of folded transportation shelf.In Fig. 8; For example, three tethers have been represented above-mentioned notion, and wherein the tethers in the middle of (i) will be gone up the transportation shelf and be coupled to down the transportation shelf; (ii) play tethers (locating) not use at ' C '; But its second end is coupled to the last bolt 120 (in the case, the fish plate 142 of each the second end 124b of middle tethers and following tethers is adjacent one another are, is positioned on the last bolt 120 of lower bracket member 118) of same supports; And (iii) go up the last bolt that tethers removably is coupled to the support element of transportation shelf, and forever be coupled to the following bolt (not shown) of the support (not shown) that is located immediately at the 3rd transportation shelf (not shown) on the middle transportation shelf.

Obviously; Among said any embodiment; Any can be fixed on the support element separately in last bolt and the following bolt, and another bolt removably is coupled to another bolt (promptly following or last bolt) of adjacent transportation shelf, and these do not exceed the spirit and scope of the present invention yet.Bolt is a detouchable with selecting down for fixing through selecting bolt, and perhaps vice versa, the vision indication that the user can confirm to have connected or opposite not bonded assembly tethers provides, and be used to the process that tethers coupled or break away from detachable bolt.In any embodiment, can carry out coloud coding to part or all anchor fittings.For example, with reference to the embodiment of Fig. 2-5, tethers 24 can be yellow, and/or support element 18 can be red perhaps other colors.In this way; The range estimation of the transfer cask that stacks can be strengthened confirm that whether tethers 24 extends between the slit of the transfer cask of adjacent one another; Be fixed on together if show the transportation shelf; Confirm that perhaps whether tethers 24 is positioned at passage 30, is not fixed on together if show them as yet.

Within principle of the present invention, can carry out various changes and modifications to above-mentioned specifically described embodiment, it receives the restriction of the scope of appended claims, as understanding according to the principle of patent law.
