The specific embodiment

The present invention is described in detail below in conjunction with accompanying drawing.Although comprised representational embodiment in the following explanation, do not get rid of the existence of other embodiment, and described embodiment can make the change that does not break away from the spirit and scope of the present invention.Whole accompanying drawing and below explanation in, if possible, identical label will be used to refer to identical or close part.

Simultaneously, the present invention is especially at a kind of runner assembly that is used for mobile shelving, and other assembly that constitutes a complete mobile shelving system part obtains describing in a preferred embodiment of the present invention equally.

Shown in Fig. 1-4 track and the runner assembly 10 that is used for mobile shelving.Assembly 10 comprises one or many tracks 12 longitudinally, be sliding combined with on every track 12 one longitudinally skid 14 to support shelf unit (not shown), in addition, also be useful on the cross member 16 that two or more skids 14 are linked together above.Representational shelf unit is suitable for being installed on two skid 14 tops, can slide along two tracks 12, is similar to consistent distance with the length of shelf unit at interval between two tracks 12.

More clearly illustrated skid 14 of the present invention among Fig. 5, Fig. 6.Skid 14 is substantially the U-shaped extruded product of a reversing, has a main line 18 that extends holding one or more roller mount 20, and along skid 14 right sides, four slits 22,24,26 and 28 of extending of a left side and upper side.Especially, slit 22 extends along the left surface of skid 14, and slit 24 extends along right flank, and slit 26 and 28 extends along upper side.Slit 22,24,26 and 28 is preferably T word groove, thereby is used to have the square nut 30 of internal thread.Nut 30 can provide quick, general structure like this, because can provide anchor point in the arbitrfary point along skid 14 for external item.

In case nut 30 moves to the position of hope, the external item that comprises an installing hole 32 is typically moved into place, thereby make installing hole 32 and nut 30 coaxial alignments.Bolt 34 extends through installing hole 32, passes slit 22,24,26 or 28, enter then nut 30 and with its screw-threaded engagement.Also have a slit 36 to extend, thereby provide further erecting device for roller mount 20 and end frame 38 along the napex central authorities of main line 18.

By design skid 14 like this, after being cut, extruded product do not need extra back processing, for example hole, fluting etc.

Next the explanation in the paragraph relates to the example of the project that can be mounted to skid 14.Some of them are necessary projects, and for example cross member 16, but other not necessarily, and for example lock bracket 40.Be appreciated that other project of not drawing and illustrating can be mounted to skid 14 equally here, for example, sensor (figure does not show), motor (figure does not show), mechanical actuation device, and similarly install.

One or more clips 42 are installed on the top of skid 14, and it is used for matching with the corresponding receiving system of below, shelf unit, for example, and the hole of a corresponding shape (figure does not show).Clip 42 comprises that an installation portion 44, one installing holes 46 extend through from installation portion 44, and a second portion 48, this second portion 48 from installation portion 44 upright and doublings to be matched with pairing receiving system.Use bolt 34 to pass installing hole 32 and be positioned at the nut 30 of slit 28, thereby clip 42 is fixed to skid 14 with cooperation.In an illustrated embodiment, each skid 14 has the clip 42 that separate two spaces.

Two cross members 16 extend between the skid 14 on the track 12 that is being spaced apart, thereby provide required support to each shelf unit.Cross member 16 is substantially I-shaped extruded product, and its left and right and upper side has slit 50,52 and 54 respectively.Preferably, slit 50,52 and 54 also is T-slot substantially, when external item being installed in wherein the time, can as described abovely equally adopt bolt/nut to connect.

Each cross member 16 uses the A-frame 56 of hollow to be connected to skid 14 at junction point.The upstanding wall of support 56 comprises outward extending outstanding 58, and outstanding 58 shape closely cooperates with both respectively the side slot 52 of cross member 16 in in the side slot 22 of skid 14.Outstanding 58 are rib shape is beneficial to pass from slit, and therefore, any impact load on support 56 has all reduced.

Installing hole 32 also is positioned on the upstanding wall of support 56.Installing hole 32 on the support 56 is positioned to make cross member 56 with respect to skid 14 vertical fixing, and just, each upstanding wall of support 56 is mounted to cross member 16 and skid 14 respectively.Again, preferably use nut 30 to be connected each assembly with bolt 34.

For skid 14 and shelf unit afterwards can be slided along track 12, skid 14 must also comprise the device of accommodating above-mentioned rollers seat 20.The main line 18 that the invention provides skid 14 holds one or more roller mount 20.

Each roller mount 20 also is the U-shaped profile of reversing, and its size is adapted in the skid main line 18.Therefore the top side face of roller mount 20 comprises two installing holes that are spaced apart 32, when roller mount 20 during along position that main line 18 is positioned to wish, can use tapping screw 34 to extend through installing hole 32 and enters slit 36, thereby roller mount 20 is firmly fixed.Such configuration means that roller does not need boring just can be mounted to skid 14.Typically, each shelf unit will comprise rollers that are positioned at each skid 14 vertical end, still, may need more roller in some cases, and the main line 18 of skid can be used for this point.

Roller mount 20 comprises bigger coaxillay aligned hole 60, and hole 60 extends through the sidewall of roller mount 20.Pin 62 extends through from the hole, thereby roller 64 is remained in the roller mount 20.Roller 64 can rotate around pin 64, and clearly, it allows skid 14 and shelf unit relative orbit 12 afterwards to move.

Mentioned end frame 38 also can be mounted to skid 14.End frame 38 not only is used for covering the end of skid 14, and it is used for also preventing that the shelf unit from tilting.Each holds frame 38 to be the form of outer rigid housing, and the shape of its internal structure corresponding to the cross section of skid extruded product, therefore holds frame 38 can be matched with an end of skid substantially.Tapping screw 34 is used for end frame 38 fix in position, and the hole 32 that tapping screw 34 is gone up from end frame 38 most extends through and enter skid slit 36.The bottom of end frame 38 is shoulders 64 of two horizontal expansions, and when it cooperates with track (described in hereinafter), it can prevent the overturning of shelf unit.Therefore hold frame 38 to constitute the device preventing tilting of assembly 10.

Referring to Fig. 7 and Fig. 8, track 12 also is made up of the one section metal that squeezes out as seen from the figure, and it comprises a hollow profile especially.Track 12 generally comprises bottom 66, inwall 68,70,72 and 74, and outer wall 76 and 78, and each several part is one-body molded separately. Outer wall 76 and 78 in the track 12 upper ends a bit of distance that extends internally is crossed inwall 70 and 72.Bottom 66 and outer wall 76,78 form triangular cross-sectional shape substantially, yet because outer wall does not converge on the summit, they define a center groove 80 of extending along track 12.

The inner geometry of track 12, particularly height, hollow profile allow firm but unobtrusive track to connect, and clearly, no longer need to be mounted to and use glue to be connected in high-precision mode with suitable fasteners.

The shape of inwall 76 and 78 inner surface has two functions.First point, in the lowermost extent of center groove 80, inwall 76 and 78 defines a V-arrangement guider 82, and it is support roller 64 surface thereon.Roller 64 is matched with guider 82 at the center, and two edges of roller 64 contact with guider.The weight of the shelf unit on roller makes roller remain on the position of hope, and makes it have sufficient frictional force to rotate through guider glibly.For preventing wearing and tearing, and strengthen guider, positioning bead (figure does not show) keeps the crinoline bands along V-arrangement guider 82, and the crinoline band generally is formed from steel.

Second point, relative depression 84 is positioned at V-arrangement guider 82 tops, and it is used to hold the shoulder 64 that is associated with end frame 38.Those skilled the in art will appreciate that, when the skid 14 of assembling is positioned on the track 12, the shelf unit is supported on skid 14, shoulder 64 limited the shelf unit all be displaced sideways, this is because the upper end of outer wall 76 and 78 stops them to move up.Therefore, prevented the inclination of shelf unit.When the top of shelf unit shelf bears heavy burden, when making it tend to, this point is extremely important.

Between inwall 68 and 70, and between inwall 72 and 74, define hollow region 86.Hollow region 86 is suitable for holding connecting pin 88, and connecting pin 88 is used for two track end are coupled together.Hollow region 86 is used for the pin 90 that is associated with the end stop bracket 92 of track 12 equally.Therefore, by using two connecting pins 90, end stop bracket 92 is mounted to the end of track 12, and for two sections of track 12 are linked together, as shown in Figure 1, has used independent connecting pin 88.

In both cases, connecting pin 88 and 90 all comprises several holes that is spaced apart 94, and all is suitable for inserting in the hollow region 86 of track 12, and final hole 94 and hole 96 coaxial alignments that extend through the bottom 66 of track 12.Reuse tapping screw 34 to cooperate coaxillay aligned hole and thus assembly to be tightened together.

End stop bracket 92 hints as its name, is the end that is used to be mounted to track 12.For example, an independent track may be connected to form by three or four orbital segments, and wherein, two are positioned at terminal orbital segment and comprise that end stop bracket 92 exceeds track in order to prevent that skid 14 from moving.Figure 9 shows that the enlarged diagram of end stop bracket 92, as seen from the figure, it comprises that one is substantially leg-of-mutton shell 98, from an inner support plate 100 outward extending connecting pins 90, and the retainer 102 of an extension between connecting pin 90, when end stop bracket 92 was mounted to track 12, retainer 102 extended into center groove 80.

Retainer 102 comprises that several ribs 104 reduce impact load to provide elastomer to cushion.Because its weight produces a large amount of power, therefore need track end stop enough firm during the shelf cell moving can cushion the bump of such power.End stop bracket 92 also comprises the anti-inclination shoulder 106 according to skid end frame 38.

The height of track 12 also needs along its length maintenance level.Preferably, even also need the height of track 12 can regulate easily the assembling successor.One or more laminations 108 shown in Fig. 2 and the cutaway view promptly are used for realizing above-mentioned purpose.Each lamination 108 is substantially rectangle, and comprises that the hole 110 of 3x2 matrix extends through itself.Comprise that in three holes 110 of lamination 108 previous columns the Q-RING of raising is around portion 112.Three holes 110 of contiguous row comprise that positioner 111 is in order to cooperate one to be positioned at the Q-RING of raising of second lamination 108 of its below around portion 112.Each stacked lamination 108 is with respect to adjacent lamination Rotate 180 degree.

At the end of track 12, adopt one or more lamination 108 (depending on the height of wanting) to be positioned over connecting pin 90 belows; Perhaps, one or more lamination 108 is positioned over connecting pin 88 belows at the joint of one or more orbital segment.Hole 110 is designed for the head of tapping screw 34, adopts tapping screw 34 be connected pin 88 and 90.Know the stacked lamination 108 that those skilled in the art will appreciate that any amount and can be added or remove the height that increases or reduce track 12 1 particular segments.

The further advantage of the improved stiffness characteristics of track extruded product is that it allows lamination 108 to have wideer interval along track 12.

Assembly 10 comprises that several can select connection inclined portion 114.Inclined plane part 114 is used for a smooth surface is provided on track 12, and prevents that track 12 from forming the security risk that trips easily.Each inclined plane part 114 comprises that one is roughly the main body 116 of rectangle, and an end of main body is a hook portion 118, and an opposite end of main body is a straight flange 120, and straight flange 120 is used for concordant with ground substantially when mounted laying.Inclined plane part main body 116 surface thereon comprises that several ribs 122 are with noticeable.Main body 116 belows are girth member 124, and its usefulness is to reduce the overall weight of inclined plane part and has kept intensity.Hook portion 118 autonomous agents 116 extend downwards, inwardly extend upward according to track 12 then again.

The track extruded product is designed for inclined plane part 114 equally.Forward Figure 10 and 11 to, between the lower end of outer wall 76 and inwall 68, and between the lower end of outer wall 78 and inwall 74, define respectively and receive the hook portion 118 of groove 82 in order to cooperate each inclined plane part 114.Especially, each inclined plane part 114 is configured to cooperate with reception groove 82 by the mode of rotation fastening.Figure 12 has shown that hook portion 118 insertions receive groove 82, next are rotated down the straight flange 120 of main body upwards to push away hook portion 118, to fasten the process that puts in place until hook portion.By the geometry designs of this inclined-plane pivot, the track 12 that can lift or overturn just realizes removing or re-mounting inclined-plane (for the purpose of smoothing again).

One rubber tube 126 is inserted in downwards and between the abutment between the surface that extends internally of the rounded end of outer wall 76 or 78 and hook portion 118.Rubber tube 126 provides downward strength and minimizes the security risk that trips easily to avoid forming that is bent upwards on inclined-plane.The further benefit of rubber tube 126 is it also as a pliable and tough binding element, assists in to handle also multiple inclined plane part to be installed simultaneously to track 12.

Inclined plane part is optionally, even owing to do not use inclined plane part 114, the track extruded product also can be designed as attractive in appearance and safety.

Finally, skid 14 can be locked in different positions along track 12.By described mode above, the lock bracket 40 shown in the figure also can be engaged to the slit 28 on a top of skid 14, perhaps other side slot.Lock bracket 40 comprises that one is mounted to the shell 128 of skid 14, and this shell 128 defines a vertical chamber, and this chamber extends downward track 12 on skid 14 next doors.This chamber comprises a upright opening 130.When desire locking shelf unit, skid moves until upright opening 130 and along track 12 and is drilled with hole 132 coaxial alignments on track 12 in advance.In case aim at, stop pin 134 passes coaxillay aligned hole 130 and 132 and insert hollow region 86, and stop pin 134 rests on the bottom 66 therein, thereby skid 14 is locked to track 12.

Provide anchor clamps 136 in order in track 12, to form prebored hole 132.As shown in Figure 1, anchor clamps 136 are for being mounted to the slim-lined construction of track 12 by lateral arrangement.Anchor clamps 136 be included in its center to lower extension 138, this extends into center groove 80 to lower extension 138, also be included in anchor clamps 136 ends to lower extension 140, be adjacent to the outer wall 76 and 78 of track 12 to lower extension 140. Hole 144 and 146 is positioned on the relative two ends of anchor clamps 136.

Anchor clamps 136 at first are suitable for being mounted on the track 12, thereby hole 144 is positioned to want the top of the point of holing.The purposes in less hole 144 is by using suitable instrument (figure do not show) to make marks on track 12, this mark to drill bit or the instrument that similarly is used for boring on track 12 play the location and guide.Unload lower clamp 12 from track 12 subsequently, make its Rotate 180 degree, and then it is mounted to track 12, thereby bigger hole 146 is positioned at the top of gauge point.Available subsequently drilling machine (figure does not show) passes the hole of track 12 at marked locations brill one.

The design that is appreciated that the assembly that some are shown and describe can be changed in the place of needs.For example, if exist a mechanical actuation device and skid 14 to interrelate, wherein a track outer wall 78 can be from stretch out bigger distance and comprise that a smooth upper surface (figure does not show) is to be used for a driving wheel (figure does not show) of center groove 80.Therefore, such track also can further comprise a hollow region 86.Under these circumstances, same lamination 108 can continue to use by revolving simply to turn 90 degrees, thereby no longer is with respect to track 12 longitudinal extensions, but horizontal expansion.
