Definitions

  • NARROW AISLE ATTACHMENT [72] lnventors: Stuart W. Sinclair; Monroe .1. Dennis, both of Houston, Tex.
  • This invention relates to an attachment for industrial lift trucks, and more particularly a narrow-aisle attachment and method which enables the truck to manipulate loads or pallets in front of and at both sides of the truck without requiring the truck to turn in the aisle.
  • the narrow-aisle attachment of the present invention generally includes a crossed arm six-bar linkage rotatably mounted on a load-support tree which is attached to a telescoping side shifter mechanism.
  • the use of the crossed arm six-bar linkage allows the front plate, to which forks or grippers or other load manipulating devices are attached, to be rotated a full 90 to either side of the truck, as well as allowing the front plate to be folded into a normal lift truck configuration.
  • the crossed arm six-bar linkage further enables the entire rotating mechanism to be contained in less width than the standard lift truck front plate and allows the pivot points to remain within the standard lift truck front plate width.
  • the load-support tree includes an equalizer to prevent twisting of the front plate and linkage when a load is engaged from the front, or either side.
  • the telescoping side shifter mechanism allows the load handling devices mounted on the front plate to be manipulated transversely of the truck when the front plate is in its normal position, and allows the front plate to extend beyond either side of the truck when it is rotated 90 from the truck axis.
  • the narrow-aisle attachment of the present invention is designed to be utilized with a standard lift truck by attachment to the standard truck carriage plate. Maximum utility of the present invention is attained when the lift truck includes an elevator mechanism, but additional side shifter mechanisms on the truck are unnecessary.
  • the thin profile of the attachment when facing forwardly prevents an excessive loss in load-carrying capacity.
  • a further object of the present invention is to provide an improved method for structuring and manipulating a six-bar linkage lift truck attachment.
  • FIGS. 1 through 7 present a diagramatic top view of the invention being manipulated to withdraw a pallet from the aisle adjacent to a lift truck,
  • FIG. 8 is a perspective view of the present invention illustrating the manipulation of a loaded pallet from the aisle, similar to FIG. 4,
  • FIG. 9 is a perspective view generally illustrating the overall configuration of the present invention.
  • FIG. 10 is a partial sectional front view of the present inventron
  • FIG. 11 is a partial sectional top view taken along line 11- ll of FIG. 10,
  • FIG. 12 is a side view, taken along line 12-12 of FIG. 10,
  • FIG. 13 is a partial top view taken along line 13- 13 of FIG. 12, and
  • FIG. 14 is a partial sectional top view taken along line 14- 14 of FIG. 12.
  • the reference numeral 10 generally refers to the narrow-aisle attachment of the present invention which is mounted on a conventional industrial lift truck 12.
  • the attachment I0 includes a front plate 14, here shown as a standard industrial lift truck tool-holding accessory carriage plate on which are hung conventional forks 16.
  • Other load-gripping and manipulating devices may be hung from the tool-holding front plate 14 in a conventional manner, or the front plate may be altered for special purposes as shown in the prior art.
  • FIG. 2 the attachment 10 and the fork 16 have been shifted to the right, so that the center lines do not correspond with that of the truck 12.
  • shifting to the extreme side releases the latch which holds the plate 14 against the attachment 10 at that side, thereby allowing the attachment to rotate the plate 14 in the opposite direction.
  • shifting the plate 14 and the attachment 10 to the extreme right unlocks the latch on the right side, allowing the attachment 10 to rotate the plate 14 to the left, as is illustrated in the successive dotted, dashed and full lines of FIG. 3.
  • the steps for rotating the plate and forks in the opposite direction are just the reverse of those indicated above.
  • the plate 14 and forks 16 shown in full lines in FIG. 3, are not aligned with the pallet 18.
  • the operator of truck 12 moves the truck forward and/or backward (as the case may be) to align the forks 16 so that they will fit within the fork space of pallet 18, as seen in FIG. 4.
  • the rotated front plate is shifted to the left so that the forks slide within the fork space of the pallet 18, in a conventional manner.
  • the forks 16 are not centered in the pallet because the near edge of the pallet must clear the attachment frame when the pallet is engaged by the truck 12 and removed from the storage point, as shown in FIG. 5.
  • the plate 14 is shifted to the extreme right and then the carriage is rotated as shown by the solid, dashed and dotted lines of FIG. 6, until the plate 14 faces to the front. If the pallet is overly deep, it may be necessary for the operator of the truck to back the truck so that the edge of the pallet clears the far corner of the storage space, when performing the operation shown in FIG. 6.
  • FIG. 8 the narrow-aisle attachment is shown in a position comparable to FIG. 4.
  • the plate 14 includes not only the forks 16, but also a carton hood attached to the plate 14.
  • FIG. 8 also illustrates the use of the narrowhaisle attachment 10 on a truck 12 to manipulate a pallet 18 located above ground level.
  • the attachment 10 is shown attached to the standard two-piece attachment and tool-holding plate 22 of the truck. This plate is, in a conventional manner, moved vertically by the elevator 24.
  • the narrowaisle attachment 10 generally includes the six-bar linkage 26, the side-shifter mechanism 28, the load-support tree 30, and the latches 32.
  • the six-bar linkage supports and pivots the plate 14, to which are attached the load-engaging devices, such as the forks 16.
  • the load-support tree 30 supports the linkage 26, and through an equalizer arrangement, prevents twisting thereof.
  • the side-shifter mechanism 28 in turn supports the load-support tree and operates in conjunction with the latches 32 to allow pivoting of the six-bar linkage 26.
  • the base of the side-shifter mechanism in turn mounts on the standard attachment and tool-holding plate 22 of the lift truck 12.
  • the six-bar linkage includes the load-support tree 30, the plate 14, and two pair of generally s qnmetrical arms 34, 36 and 38, 40.
  • the tree 30 generally includes brackets 42 and M,
  • pivot pins 46 pivotally supporting inner arm 34 and pivot pins 48 pivotally supporting inner arm 36 at both the top and bottom.
  • lnterconnecting and allowing pivotal movement between arms 34 and 38 are pivot pins 50, while similarly interconnecting arms 36 and 40 are pivot pins 52 at both the top and bottom.
  • interconnecting and allowing pivotal movement of the front plate 14 and outer arm 38 are pins 54, while similarly interconnecting the plate 14 and outer arm 40 are pins 56.
  • pins 54 and 56 are not coaxial, but are offset, so that when the plate 14 is parallel to the lift truck plate 22, the arms 38 and 40 cross. Plate 14 therefore forms a link in the six-bar linkage.
  • Extension of ram 58 causes arm 34 to pivot outwardly from a position adjacent the frame 70 of the attachment 10 to a position somewhat past perpendicular to the frame, as seen in FIG. 11.
  • extension of the ram 60 causes the arm 36 to move from a position adjacent the frame 70 to a position somewhat past perpendicular thereto, as seen in FIG. 11.
  • the rams are extended at the same time so that the arms butt together as shown in FIG. 11. Retraction of the two rams causes the arm 34 and 36 to rotate about the pivots 46 and 48 until the pivots 50 and 52 are adjacent the frame 70.
  • the rams 58 and 60 may not be extended.
  • Plate 14 includes a latch assembly 32 at either end thereof.
  • the latches are designed to engage with roller catches 72 and 74.
  • Roller catch 72 is mounted on outer arm 38 adjacent the pivot pin 50, while roller catch 74 is mounted an outer arm 38 adjacent pivot pin 52.
  • the latches 32 on both sides of plate 14 are engaged with their respective roller catches 72 and 74.
  • roller catch 74 is disengaged, in a manner to be hereinafter described, and the front plate remains latched only to roller catch 72. This retains plate 14 adjacent arm 38.
  • roller catch 72 is attached to arm 38.
  • bracket 75 Extending backwardly from plate 14 is the bracket 75 to which is pivotally attached a cam 76.
  • the cam 76 prevents movement of roller catch 72, and consequently holds plate 14 adjacent arm 38.
  • Attached to the cam 76 is a suitable operating lever 78 which is manipulated to rotate cam 76 in the direction indicated by the arrow, to release catch 72.
  • the cam 76 is suitably biased, as by a spring or rubber block, to ordinarily remain in the position shown in FIG. 13.
  • the symmetrical latch on the opposite end of plate 14 is shown in FIG. 11 with the addition of prime marks to the various numerals.
  • the racks 80 and 82 in combination with the pinions 84 and 86, operate as an equalizer to prevent twisting from the vertical of the tree 30 when loads are manipulated by appropriate tools attached to plate 14.
  • the side-shifter mechanism 28 is here shown to be telescoping so that it includes primary and secondary hydraulic rams to selectively position the tree 30 transversely across the front of the lift truck 12.
  • the secondary rams are actuated in response to an increase in resistance to movement and constitute a refinement of the present invention, giving a somewhat broader range of operating area, and may be dispensed with if less maneuverability can be tolerated. Other devices may be utilized to provide equivalent movement.
  • the primary side-shifting mechanism includes a motor here shown as rams 102 and 104.
  • rams 102 and 104 are here shown as single-acting, with the cylinder ends being attached to the frame '70 oriented in opposite directions.
  • Attached to the piston rod 106 of ram 102 is a sprocket 108, while attached to the piston rod 110 of ram 104 is a sprocket 112.
  • Attached to opposite sides of the frame 70 adjacent rams 102 and 104 is a chain 1 14 which engages the sprockets 108 and 112.
  • the chain 114 may have suitable adjustment means 116 at either or both ends attaching the chain to the frame 70.
  • the center of the chain is attached to the load-support tree 30 by bracket 118.
  • Suitable hydraulic connections are made in a conventional manner to the rams 102 and 104. Entry of hydraulic fluid into ram 102 causes the piston rod 106 to extend, rotating the chain 114 about the sprocket 108 in the direction of the arrow, causing bracket 118, and therefore tree 30 to move in the same direction as the piston rod extends, only twice as fast because of the mechanical advantage. Similar, but opposite movement results when ram 104 is energized.
  • the tree moves across the face of the frame 70 and is supported by the various rollers 90, 94 and 98. This in turn causes the six-bar linkage 26 to similarly move transversely across the face of the frame 70. This movement is substantial only if the plate 14 is positioned perpendicular to the frame 70. With the foregoing described primary side-shifter mechanism, the plate 14 may be manipulated to the edge of the frame 70.
  • the frame 70 itself may be shiftable to make the present invention more maneuverable. This is accomplished by the secondary side-shifting mechanism.
  • the sub-frame 120 includes an upper bracket 122 and a lower bracket 124 which are fixedly attached, in a conventional manner, to the front carriage plate 22.
  • a Z-shaped bearing 126 is interposed between the upper bracket 122 and the frame 70 to support the frame so that it may slide on the upper bracket.
  • a vertical bearing 128 serves a similar purpose between the frame 70 and the lower bracket 124.
  • Extending upwardly from the upper bracket 122 of the sub-frame 120 is a lug 130, which protrudes through a slot 132 in the frame 70- This slot is best seen in FIG. 1 1.
  • Secondary motor means are interposed between the frame 70 and the lug 130, here shown as secondary rams 134 and 136.
  • One end of each ram is attached to the frame 70, and the opposite operative end is connected to the lug 130.
  • Actuation of ram 134 results in sliding the frame 70 away from the lug 130, which is fixedly attached to the lift truck carriage plate 22 through the upper bracket 122. In this manner, the frame 70 may be maneuvered bodily over a portion of the face of the carriage plate 22, thus extending the side-shifter range of the present invention.
  • the rams 134 and 136 are hydraulically actuated in a conventional manner.
  • centering springs 138 which engage the subframe 120. The purpose of these springs is to provide a specific resistance before unlatching occurs and to partially center the frame 70 with respect to the sub-frame 120 when it is not desired that the frame 70 remain at the extreme end of its travel with respect to the sub-frame.
  • the present invention has provided an attachment for lift trucks which is particularly useful in manipulating loads in front of and at both sides of a lift truck.
  • the method of the present invention is felt to have been adequately described with reference to the structure and generally includes maintaining two links of a six-bar linkage overlapped with one interposed link therebetween, and selectively latching the interposed links to the overlapped arms.
  • a narrow-aisle attachment for use with a lift truck including:
  • rotating means mechanically interconnecting each of the inner arms and the tree to rotate the arms relative to the tree
  • latch means selectively interconnecting each of the outer arms to the plate
  • side-shifter means supporting the tree for selective shifting of the tree transversely to the truck
  • equalizer means interconnecting the load support tree and side-shifter means to prevent relative twisting therebetween.
  • rotating means includes hydraulic motors pivotally interconnected between the tree and each of the inner arms.
  • latch means includes locking cams on the plate which engage catches on the outer arms, and wherein the means for selectively actuating the latch means includes cam-locking fingers which engage the locking cams at selective positions of actuation of the sideshifter means.
  • a work-engaging means providing a link in the six-bar linkage
  • latch means selectively locking each of the outer arms to the work-engaging means
