Abstract

An automatic locking apparatus releasably locks together a studded end plate connector to a notched vertical frame column of a storage rack. The automatic lock includes a vertical lever positioned adjacent one surface of an end plate connector when the end plate connector is mounted on a vertical frame column. A locking pin and tension support extend from the inside face of the vertical lever through the end plate connector. The tension support has a protruding end extending past the end plate connector and a tension device mounted on the protruding end to create a force for pulling the inside face of the vertical lever toward one surface of the end plate connector. The locking pin has a length that allows it to extend through the top of a notch or other aperture in the frame column when studs of the end plate connector are positioned in the bottom of corresponding notches in the frame column, preventing withdrawal of the studs from the notches. The locking pin automatically retracts as the end plate connector comes into contact with the frame column and automatically locks after the studs slide into the bottom of their corresponding notches of the vertical frame. The end plate connector can later be disconnected from the vertical column by pulling on the vertical lever to withdraw the locking pin, allowing the studs to slide up from the bottom of the notches.

Description

AUTOMATIC TRABAZ DB VIGA Background The present invention is directed to the field of systems for storage shelves. More particularly, the present invention is directed to an improved locking apparatus to prevent uncoupling of the longitudinal beam plate connectors from the columns of the vertical support structure in storage rack systems with modular structure. Storage rack assemblies with modular structure are constructed around a plurality of columns of vertical structure, where each of the columns of the structure has one or more lines of support grooves placed up and down the height of the structure. column. The grooves are generally tapered, having an inverted tear shape causing the grooves to be wider near the top than the bottom. The racks of the storage racks are placed transversely between the columns and share the weight of the stored loads. The end of each of the beams typically includes a longitudinal plate connector having two or more rods in it to engage the grooves of a column of the vertical structure. Each of the rods has a base portion coupled directly to a connector surface of the longitudinal plate and a head portion remote from the base and having a diameter substantially greater than the base. To couple a slot and secure the shelf beam to a column of the structure, each of the heads of the stem must have a diameter small enough to enter its respective slot near the top portion of the slot. Each of the heads of the shank must also have a diameter that is sufficiently long so that it can not leave the lower portion of the slot. The diameter of the base of each of the rods should be small enough to enter the upper portion or the lower portion of the groove. During the coupling, the head of each of the rods passes entirely through the upper portion of a corresponding groove, leaving only the base portion until surrounded by the groove. Being narrow enough to enter the lower portion of the groove, the base allows the rod to slide downward under the force of gravity while the head of the rod remains extended when going through the slot. Once the rod enters the lower portion of the slot, the head of the rod remains positioned beyond the surface of the column of the structure that is distant from the connector of the longitudinal plate. However, by having a diameter greater than the portion of the bottom groove, the head of the stem can not pass through the groove or withdraw laterally therefrom. While the rods are not forced to slide back into the upper portion of their corresponding slots, the heads of each of the rods continue to secure the longitudinal plate connector and the shelf beam in place. Normally, the weight of this common storage shelf beam combined with any shared load is sufficient to prevent upward movement of the stems, allowing the longitudinal plate connectors to remain securely in place. However, there are certain situations in which the scions can be uncoupled by an accidental or unintentional upward force. These forces are often exerted during the loading and unloading of loads, during the construction or reconfiguration of storage shelves, or when the shelves of storage or adjacent charges come into contact with another storage or loading shelf. As a result of this, the correct locking mechanisms must often be constructed so that they support an upward force of 1., 000 pounds or more. The previous locking devices include simple bolts, pin devices, boterolas and spacers. These devices achieve the result of securing a storage shelf in place and are usually economical and reliable. However, many of these devices require a lot of manual work to place them, secure them individually and then make sure that the devices are correctly coupled, 15 often requiring the use of additional tools. The same manual work must be exercised later during the disassembly. This manual work also presents an additional risk in that an accidental force 20 could be exerted upwards and unsecured by a user during assembly or disassembly, imposing an additional safety hazard for users or other persons who may be in the closeness of the storage shelf. Other previous locking devices incorporate automatic coupling mechanisms coupled to the connector of the longitudinal plate. In these devices, the locking function occurs automatically once the base of the stem slides down and enters the lower portion of a slot. More often, a single bolt or tongue loaded with spring is automatically pressed onto the entry of the rods in the grooves of a structure column. • 1 time the stem slides down, the spring loaded bolt or tongue finds a slot or other corresponding opening in the column of the structure, allowing the bolt or tongue to be pressed and enter the opening, securing the stems and the longitudinal plate connector in place. Although these prior devices eliminate the need to manually secure the storage beams in place after configuration, they typically suffer from a number of inherent disadvantages. Among the existing designs, some fall to eliminate the need for an additional tool during assembly or disassembly. In other automatic locking devices that eliminate the need for additional tools, the construction costs are significantly higher, making that the devices are prohibitive in their cost for mass production. These designs also often require the use of an outer casing assembly to contain a spring and other tension device. When an arrangement of this nature is used, a single safety bolt can be limited to a linear movement, which can, in turn, require the use of more than one finger by the user to give effect to the release of the locking mechanism. For example, this apparatus may require that a knob be held on the safety bolt instead of only a lever being rotated. In some earlier designs that allowed for simple lever operation using a finger, as with a spring-loaded tongue, significant problems have arisen with respect to the breaking of the spring tabs, the loosening, or falling out of their respective connectors. of the longitudinal plate. SUMMARY The present invention is an automatic latching apparatus for releasably securing a longitudinal plate connector with rods to a vertical structure column with grooves of a storage shelf. The automatic lock includes a vertical lever adjacent to a surface of the connector of the longitudinal plate when it is installed on the connector of the longitudinal plate. A lock bolt and a tension bracket extend from the inside face of the vertical lever through the connector of the longitudinal plate. The tension support has a protruding end extending to pass the connector of the longitudinal plate and a tension device mounted on the protruding end to create a force to pull the inner face of the vertical lever towards the surface of the plate connector longitudinal The locking bolt has a length that allows it to extend through the top of a slot or other opening in the column of the structure when the pins of the connector of the longitudinal plate are placed in the lower part of the corresponding slots in the column of the structure, preventing the rods from being removed from the grooves. The lock bolt is also mounted to automatically retract while the connector of the longitudinal plate comes into contact with the column of the structure and to automatically secure itself after the rods slide into the lower part of their corresponding grooves. The connector of the longitudinal plate can be disconnected later from the vertical column when pulling on the vertical lever in order to remove the bolt from the lock, allowing the rods to slide up from the bottom of the slots.

Detailed Description of the Preference Making Forms With reference to the drawings, numbers and identical reference letters designate the same or corresponding part along several figures shown in the drawings. Figure 1 shows a storage shelf of modular structure 20 of the type of the subject matter of the invention. The components WILLY 12 OF WINTER The basic features of a storage rack storage system with a modular structure include a plurality of vertical structure columns 24 for supporting one or more horizontal storage rack beams 28, mounted transversely on the columns of the structure 24 through the wider dimension of the shelf 31. Cross-sectional horizontal pieces that do not share load 25 and diagonal cross pieces 26 that serve to secure and permanently space the columns of the adjacent structure 24 in relatively fixed positions through the narrowest dimension of the shelf 27. loads shared in the storage system, placed on the storage shelf beams 28 which are coupled to the columns of the structure 24 with the connectors of the longitudinal plate 32. Normally, a flat surface (not shown), such as a shelf, will be placed between two or more storage shelf beams 28 for p Roveer a surface area for storage. The storage shelf 20 is modular because the connectors of the longitudinal plate 32 can be disconnected from the columns of vertical structure 24 and reconnected at alternating points along the height of the columns of vertical structure 24. This variable in the placement of the connectors of the longitudinal plate 32 allows the user to selectively place the beams of the storage shelves 28 at different relative heights within the storage shelf 20 to individually meet the particular storage requirements of the user. As shown in Figure 2, the connectors of the longitudinal plate 32 are connected to the vertical structure columns 24 with rods 40 which are inserted into tapered grooves 36 arranged in one or more of the vertical lines along the height of the vertical structure column 24. The rods 40 have bases 48 coupled to the connector of the longitudinal plate 32 and the heads 44 with diameters substantially wider than those of the bases of the rods 48. The grooves 36 in the column of the structure vertical 24 are teardrop shaped, each having an upper portion 52 which is substantially wider than the lower portion 56. The upper portion 52 of each of the slots 32 is sufficiently wide to accommodate the head 44 of a stem 40, while that the lower portion 56 of each of the slots 36 is sufficiently wide to accommodate only the base 48 of a shank 40, the The lower part of the slot 56 is narrow enough to prevent the head 44 of a shank 40 from passing through the slot 36. During the selective configuration of the storage shelf 5 20, the storage shelf beams 28 are placed along of the vertical structure column 24 at selected heights that represent the desire to level the storage. The rods 40 of the connectors of the end plates 32 are inserted in corresponding grooves 36 in the upper part 52 of each of the grooves. The head 44 of each of the rods 40 passes entirely through its respective groove 36 until the groove 36 surrounds only the base 48 of the rod 40. Having a diameter sufficiently narrow at its base 48, the shank is free to enter the lower part 56 of the groove 36 and slides into the lower part 56 while the shelf beam 28 moves downwards under the force of gravity . 20 Referring briefly to Figure 7, once the rod 40 slides in the lower part 56 of the groove 36, the head 44 of the rod 40 continues to extend completely out of the column of the vertical structure 24 on one side distant from the connector of the longitudinal plate 32. Al having a diameter wider than the lower part 56 of the groove 36, the head 44 of the rod 40 can not be withdrawn laterally from the lower part 56 of the groove 36. This is how, the connector of the longitudinal plate 32 remains secured in a position relative to the column of vertical structure 24 while the rods 40 remain in the lower parts 56 of their respective grooves 36. However, in the absence of a locking mechanism, only the gravity prevents the possible disengagement of the rods 40 from the grooves 36 in the event that the beam of the shelf 28 is subjected to a force, accidentally or unintentionally upward. Thus, a locking device should be used to restrict unintentional uncoupling of the rods 40 out of the slots 36. In accordance with the principles of this invention, an automatic lock 10, mounted on the connector of the longitudinal plate 32, inserts a security bolt 4 in the upper portion 52 of a groove 36 while the rods 40 of the connector of the longitudinal plate 32 slide in the lower portions 56 of their respective grooves 36. With reference to FIGS. 3a and 3b, the Locking apparatus 10 includes a vertical lever 8 having a needle tongue 12.

In one of the preferred embodiments, the needle tongue 12 is oriented at an angle to the vertical lever 8, allowing the user to operate the lever using a needle tab. Although the angled needle tongue 12 is shown and described in this particular embodiment of the invention, it will be appreciated that the lever may include other extensions, tapers, or correct openings for a single finger operation without departing from the spirit and the scope of the invention. A tension support 15 is mounted on the inner face 13 of the vertical lever 8, where the tension support 15 has a protruding end 16 which extends through the connector of the longitudinal plate 32 after the installation of the automatic lock 10. A tension device 17 is placed in the connector of the longitudinal plate 32 to exert a constant spring force between the tension support 15 and the connector of the longitudinal plate 32. Although the tension device 17 shown and described in the Figure 3 comprises a spring, it will also be appreciated that both a spring, a rubber encapsulation or a similar elastic element can be incorporated into the design within the scope of the invention. In some embodiments, the spring may compressed in position with a separate retainer element 18 mounted on the protruding end 16 with a pivot lock fastener. By exerting a force between the tension holder 15 and the connector of the longitudinal plate 32, the tension device 17 biases the inner face 13 of the vertical lever 8 against a surface of the connector of the longitudinal plate 32. A safety bolt 4 is also mounted on the inner face 13 of the vertical lever 8. Referring now to Figure 4, the security bolt 4 extends through the connector of the longitudinal plate 32, while the vertical lever is adjacent to the surface of the connector of the longitudinal plate 32 and also has a length sufficiently long to extend through an adjacent groove 36 in the column of the vertical structure 24 when the rods 40 of the connector of the longitudinal plate 32 are secured in the lower portions 56 of the corresponding grooves 36. The safety bolt 4 is also positioned to make contact with a contact area of the bolt 19 on the surface of the vertical structure column 24 when the rods 40 of the connector of the longitudinal plate 25 extend 32 through the part 52 of each of the corresponding grooves 36 of the stem, thus preventing the extension of the safety bolt 4 until the rods 40 slide into the lower portions 56 of their respective grooves 36. After the insertion of the rods 40 into the upper part 52 of the grooves 36, the sliding downwards of the rods 40 within the lower parts of the groove 56 makes the operation the automatic securing of the automatic lock 10. With reference again to Figure 4, it is installed an automatic lock 10 in a connector of the longitudinal plate 32 having a plurality of rods 40. The rods 40 are still not inserted into the slots 36 of the connector of the longitudinal plate 32, and the vertical lever 8 is in its polarized position adjacent to the connector surface of the longitudinal plate 32. The two protruding ends 16 of the tension holder 15, with its tensioning device 17 and the safety bolt 4 extend through the connector of the longitudinal plate 32, although neither of the protruding ends 16 nor the safety bolt 4 still extend through the column of the vertical structure 24. Here there is no physical connection still between the connector of the longitudinal plate 32 and the column of the vertical structure 24. Now consider, with reference to Figure 5, the insertion of the rods 40 into the groove 36. The heads 44 of the rods 40 are only narrow enough to fit through the top 52 of each of the grooves 36. The automatic lock is placed in the connector of the longitudinal plate 24 so that the insertion of the rods 40 into the upper parts of the groove 52 brings the tension support 15 to be aligned with the upper part 52 of its own groove 36, allowing the protruding end 16 of the tension support 15 enter the slot 36 and extend through the column of the vertical structure 24. The relative position of the automatic lock 10 also leads to the safety pin 4 so that it aligns with the contact area of the pin 19 on the surface of the column of the vertical structure 24.? 1 time that the rods 40 are inserted into the upper parts of the groove 52, the safety bolt 4 makes contact with the contact area of the bolt 19, which in turn exerts force against the safety bolt 4 and the vertical lever 8 opposite the polarizing spring force of the tensioning device 17. The vertical lever 8 consequently retracts from its position adjacent to the column of the vertical structure 24 while the securing bolt 4 is pushed back under the compression of the connector of the longitudinal plate 32 against the column of the vertical structure 24. The automatic securing action occurs while the rods 40 slide from the upper portions of the groove 52 towards the lower parts of the groove 56. Referring now to Figure 6, the sliding action of the longitudinal plate connector 32 slides the rods 40 from the top 52 of each of the slots 36 to the bottom 56. While the connector of the longitudinal plate 32 moves downward, the protruding end 16 of the tension support 15 also moves towards the lower part 56 of its respective groove 36, while the safety pin 4 continues to make contact with the area of pin 19, sliding down the surface of the column of vertical structure 24. The compression between the connector of the longitudinal plate 32 and the column of the vertical structure 24 continues to push the safety pin 4 against the polarizing force of the spring of the tension device 17 until the pin of safety 4 comes into contact with the upper part 52 of the groove 36 in the column of the vertical structure 24. The safety pin 4 is mounted on the vertical lever 8 so that the safety pin 4 does not come into contact with a part 52 of the groove until after the rods 40 enter the lower portions 56 of their corresponding grooves 36. After the rods 40 enter the lower portions 56 of their respective grooves 36, the bolt of safety makes contact with the upper part 52 of a respective groove 36. The contact with the groove 36 releases the compression against the safety pin 4. Consequently, the polarizing force of the spring of the tensioning device 17 automatically ensures the longitudinal plate connector in place by exerting a force against the vertical lever 8, pushing the vertical lever 8 backward in a polarized position with its internal face 13 adjacent to the connector surface of the longitudinal plate 32, thus extending the securing bolt 4 into the upper portion 52 of the groove 36. In some embodiments of the invention, the securing bolt 4 includes an additional safety bolt groove 55 in which the upper surface of the part higher of slot 52 engages over the pin extension 4. Once the automatic securing action occurs, it is not possible for the rods to be removed from their respective grooves 36 without first releasing the apparatus from the automatic lock 10. Having a diameter greater than the width of the lower parts of the slot 56, it is not possible for the rods 40 to be laterally withdrawn from the grooves 36. With the safety bolt 4 extended in the upper part 52 of its respective groove 36, it is also not possible for the connector of the longitudinal plate 32 it slides up sufficiently for the security bolt 4 to move past the top of its corresponding slot 52. Therefore the security apparatus prevents the rods 40 from sliding towards the upper portions 52 of the corresponding slots 36 of the rods, securing the rods 40 and the connector of the longitudinal plate 32 in place. Once the rods 40 and the connector of the longitudinal plate 32 are secured in place, they can be removed from the vertical structure column 24 only by manually releasing the automatic locking device 10. To release the work 10, a user pulls back on the vertical lever 8 when pulling the angled needle tongue 12. This pulling action moves the vertical lever 8 away from the polarized position adjacent to the connector surface of the longitudinal plate 32, thus pulling the safety pin 4 out of its respective slot 36. The safety bolt 4 has a length that allows the safety bolt 4 to be removed from the groove 36 when the vertical lever 8 is pulled away from the connector surface of the longitudinal plate 32.. Only after the securing bolt 4 is removed from the upper part 52 of its groove 36 the rods 40 can move freely upwards towards the upper part 52 of their respective grooves 36, then the rods 40 can be freely withdrawn from their parts. grooves 36, allowing the connector of the longitudinal plate 32 to be disconnected from the column of the vertical structure 24. While sliding the connector of the longitudinal plate 32 and the rods out of their respective grooves 36, the user must continue to pull the vertical lever 8 in order to prevent the tensioning device 17 from extending the securing bolt 4 and again automatically securing the rods 40 and the connector of the longitudinal plate 32 in place. The people qualified in technology will recognize that many modifications to the automatic lock described above may be made in the description of the preferred embodiments of this invention without departing from the spirit and scope of the invention. Various alternative methods and techniques can be incorporated to couple the safety bolt 4, the vertical lever 8, and the tension support 15 in a fixed and solid interconnected component. The embodiment described in Figure 8a includes a substantially cylindrical safety pin 4 with a rear end of the bolt 60 inserted through an opening in the vertical lever 8 and land on the rear part of the lever. In Figure 8, the described embodiment similarly includes an inserted cylindrical safety bolt 4 where the rear end of the bolt 60 is welded in place. In an illustrative contrast, the tension support 15 is directly screwed into position in the vertical lever 8. It is also possible to make any combination of the subcomponents from a solid forged material or a sharp piece. Figure 10 describes an automatic lock 10 having a safety bolt 4, a vertical lever 8, and a tension bracket 15 formed from a single component of solid forged In the embodiment described in Figure 11 only two of the components, the security bolt 4 and the vertical lever 8, comprise a single solid component. In this embodiment, a J-shaped member 64 is bent into shape from a single length of the material as a metal and inserted into two separate openings in the vertical lever 8 to form a single component. There are also alternative methods and configurations for providing tension between the tension holder 15 and the connector of the longitudinal plate 32. Although the design shown and described in the preferred embodiment incorporates a spring component of the tension device 17, the Figure 12 discloses an alternative resilient rubber encapsulation 70 or similar elastic material extending over the length of the tension holder 15 from the connector of the longitudinal plate 32 of the protruding end 16. The resilient encapsulation 70 provides spring tension between the support tension 15 and the connector of the longitudinal plate 32 through elastically reverted to its configured shape, polarizing the inner face 13 of the vertical lever 8 against the surface of the connector of the longitudinal plate 32. The outer surface of the tension support 15 it comprises a series of surface jaws 74 extending from the vicinity of the connector of the longitudinal plate 32 to the protruding end 16 of the tension support 15 and serving to secure the inner surface of the resistant encapsulation 70, securing the encapsulation 70 in its place on the tension support 15. In this embodiment, the surface jaws also eliminate the need for a separate retainer element 18, mounted on the protruding end 16 to give effect to the compression of the encapsulation 70 between the tension holder 15 and the connector of the longitudinal plate 32. In the embodiments where a sealing element 18 is required separately to effect the compression between the tension support 15 and the connector of the longitudinal plate 32, there are many alternatives for securing the retainer element to the tension holder 15. With reference to Figure 11, the retainer member 1 8 may comprise a single retainer ring mounted on the protruding end 16 of the tension holder 15 for capturing an end of the tension device 17. In this embodiment, the retainer element 18 includes a plurality of ends of rail grippers. pointing inwards that are fastened on the protruding end 16 and the tension holder 15. Alternatively, as described in Figure 10, an inward jaw spring cap can also be used as a retainer element 18. In this embodiment, the retainer element 18 comprises a thin piece of tongue-shaped metal with a capacity of of securely holding the tension holder 15. In Figure 9, the retainer member 18 comprises a tapered bottom portion extending from the protruding end 16. A suitable retainer element can also be formed from the support body of the holder. tension. Figures 8a and 8b describe a correctly implemented automatic latch for having a flat tubular tension holder 15 with a wedge-shaped retainer element 18 formed at the end of the protruding end 16. The tension device 17, in this embodiment, it is tapered to engage the retainer element 18. During assembly, the tension device 17 slides over the retainer element 18, expanding as it passes due to the wedge shape of the element. After installation, the tension device 17 remains secured behind the retainer element 18 due to the taper and wedge shapes of the components. A suitable retainer member of the body c can also be formed; of the voltage holder 15 for use with non-tapered tensioning devices. By briefly referring to the embodiment in Figure 3a, the block-like extension of the protruding end 16 can be twisted at an angle of about ten degrees or more from the tubular surface of the tension holder 15. This modification has the effect of creating a compression barrier against the tension device 17, essentially by adding an optional additional retainer element 18 to achieve the same compression effect between the tension holder 15 and the connector of the longitudinal plate. Figures 13a and 13b illustrate a further embodiment including a pressure pin 80 and a plurality of slots 84 at the end C protruding 16 of the tension support 15. In this embodiment, the pressure bolt 80 extends within the length of the tension holder 15. A flange end 86 engages the tension holder at the rear of the vertical lever 8. The length of the pressure bolt 80 is almost so long as the voltage holder 15, and in Figure 13a, it is 29 DE extends closely to the grooves 84 of the protruding end 16. During assembly of this embodiment, a detent element fits over the protruding end 16 of the tension holder. After the retainer member 18 is placed on the protruding end 16, the pressure bolt 80 is pushed into the body of the tension holder 15, as shown in Figure 13b. Within the tension holder 15, the bolt contacts the inner surfaces of the tension holder 15 in the slot 84. The inner surface near the slots 84 is closely spaced, resulting in an exterior buckling 88 that takes its shape in the protruding end 16 of the tension holder 15 while the bolt is pushed inwardly. This camber 88 secures the retainer element 18 against the tension device 17. Those skilled in the art will recognize that the various functions of this invention described above can be used in various combinations with other elements without departing from the scope of the invention. Thus, the appended claims are intended to be interpreted to cover the equivalents of locking devices that are not based on spirit and scope of the invention.
