Abstract

A storage system that includes a storage rack and a plurality of containers. The storage rack includes a frame assembly, a plurality of shelf members, and at least one biasing member. The biasing member is positioned on one of the shelf members and extends into a storage space defined two adjacent shelves that is sized to receive a container. The biasing member applies a biasing force upon a container positioned in the storage space thereby retaining the container in the storage rack. The biasing member can be a separately formed piece that is mounted to the shelf member. Alternatively, the biasing member can be formed integral with the shelf member such that addition of the biasing member to the storage rack does not require additional material.

Description

TECHNICAL FIELD

The present disclosure generally relates to storage devices and systems, and more particularly relates to storage devices and systems for use in holding containers and related methods.

BACKGROUND

Different types of specimen storage systems and methods are used in the medical and biological industries. One example storage system is a storage rack that holds a plurality of containers, wherein the containers each house frozen biological specimens. An example storage system includes a plurality of compartments sized to receive the containers. The compartments are stacked vertically. Access to the compartments is available along a single side surface of the storage system. The storage system holds the containers while the containers are placed in a frozen environment that maintains the frozen state of the biological specimens. Some example frozen environments include chest freezers that maintain temperatures as low as −100° F., and liquid Nitrogen freezers that can maintain temperatures as low as −300° F. These types of freezers are typically relatively deep, requiring that the storage racks that hold the containers to be relatively tall.
Storage racks with a locking rod that traverses the openings into the storage rack where the containers are inserted have been used to help prevent the containers from falling out of the storage racks during storage and the retrieval process. Locking rods result in several disadvantages. One disadvantage relates to the fabrication problem of providing alignment of all the holes in the storage rack for the locking rod to fit through. Another disadvantage is the extra height and depth of the storage rack required for the locking rod. The most significant disadvantage of locking rods is the operation challenge of having to remove the locking rod to retrieve a sample. When handling a relatively tall storage rack, the locking rod is equally long and must be drawn upward a height sometimes as tall as the operator. Handling the locking rod can be difficult when wearing necessary protective equipment such as gloves that protect against freezer burn when handling the storage rack. Furthermore, removal of the locking rod has to be done while the rack is out of the refrigerated environment, which creates the potential of the specimens inside and outside of the refrigerated environment warming up and thawing out while handling the storage rack.
Another storage rack feature that has been used to retain containers are spring clips mounted to the sides of the storage rack. The spring clips are welded in place and exert a biasing force on the sidewalls of the container to hold the containers within the storage rack. Side mounted spring clips also have many disadvantages, such as added cost, increased manufacturing complexity, and additional width requirements for the storage rack.
A storage system that addresses these and other shortcomings would be an advance in the art.

SUMMARY

One aspect of the present disclosure relates to a storage system that includes a storage rack and a plurality of containers. The storage rack includes a frame assembly, at least one shelf member, and at least one biasing member. The at least one biasing member is positioned on the at least one shelf member and extends into a storage space sized to receive a container. The at least one biasing member applies a biasing force upon a container positioned in the storage space thereby retaining the container in the storage rack. Typically, the force required to remove the retained container from the storage rack is a force greater than gravity forces. The at least one biasing member can be a separately formed piece that is mounted to the at least one shelf member. Alternatively, the biasing member can be formed integral with the at least one shelf member such that addition of the biasing member to the storage rack does not require additional material as compared to a similar storage rack that is void of a biasing member.
It is desired to produce another system which will retain the specimens during storage and retrieval and to allow for easy, quick retrieval of a desired specimen with reduced risk of warming all the stored specimens.
The above summary is not intended to describe each disclosed embodiment or every implementation of the inventive aspects disclosed herein. Figures in the detailed description that follow more particularly describe features that are examples of how certain inventive aspects may be practiced. While certain embodiments are illustrated and described, it will be appreciated that disclosure is not limited to such embodiments.

DETAILED DESCRIPTION

The Example Storage System of FIGS. 1-4C

An example storage system and related methods of storage are now described with reference to FIGS. 1-4C. The storage system 10 includes a storage rack 12 and a container 14. The storage rack 12 defines a plurality of storage spaces 70 into which the container 14 can be removably inserted and retained.
The storage rack 12 includes a frame assembly 16, a plurality of shelf members (first, second and third shelf member 18, 20, 22), and first and second biasing members 24, 26. The frame assembly 16 includes a pair of front supports 30, and a pair of rear supports 32 that define four corners and four side surfaces of the storage rack 12. The supports 30, 32 are aligned vertically generally parallel to the Z axis of the XYZ coordinate system shown in FIGS. 1 and 2. The frame assembly 16 further includes a top cover 34 having a pair of vertically downward facing flanges 39, and first and second handles 36, 38 positioned on an upper surface of the top cover 34.
The shelf members 18, 20, 22 each include a top support surface 40 facing a generally vertical upward direction, a bottom support surface 42 facing an opposite, vertically downward facing direction, and a pair of side flanges 44, 46 that extend in a generally vertically upward direction and are aligned along side edges of each shelf member. The shelf members 18, 20, 22 are positioned vertically relative to each other with the top and bottom support surfaces of each shelf member arranged in parallel.
Individual storage spaces 70 sized to receive the container 14 are defined by spaces within the frame assembly 16 that are positioned between adjacent shelf members 18, 20, 22 and front and rear supports 30, 32. The side flanges 44, 46 of the shelf members 18, 20, 22 restrict access into the storage spaces 70 from opposing sides 31, 33 of the frame assembly 16 (see FIG. 1). The rear supports 32 of the frame assembly 16 include flanges that extend along the side surfaces 31, 33 of the frame assembly 16 and also along a rear surface 35 of the frame assembly 16 thereby also restricting access into the storage spaces 70 from the side 31, 33 and rear surfaces 35 of the frame assembly 16. Access to the storage spaces 70 is provided along a front surface 37 of the frame assembly 16.
In alternative arrangements, one or more of the opposing side 31, 33 and rear surfaces 35 can also be configured to provide access into the storage spaces 70. In one example, the rear supports 32 are configured with a single flange portion extending along the side surfaces 31, 33 of the frame assembly 16 without a flange extending across the rear surface 35 of the frame assembly 16, thereby providing access into the storage spaces 70 via the rear surface 35 of the frame assembly 16 in addition to the front surface 37 of the frame assembly 16.
Referring to FIG. 3, the first and second biasing members 24, 26 include a connection portion 50 that engages the shelf member top or bottom support surface 40, 42 (e.g., first shelf member 18), a first segment 52 and a second segment 54. A first bend 56 defines the connection portion 50 from the first segment 52, and a second bend 58 defines the first segment 52 from the second segment 54. FIGS. 4A-C illustrate several example configurations for the first and second biasing members 24, 26. Other bend configurations are possible with the addition of further bends or the elimination of one of bends 56, 58. Each bend configuration can provide a unique biasing force that is applied to the container 14 positioned in the storage space 70 (e.g., the direction in which the biasing force is applied and the magnitude of force).
The biasing members 24, 26 can be positioned on either the top or bottom support surface 40, 42 of a given shelf member 18, 20, 22 of the storage rack 12. When a container 14 is positioned within a storage space 70 in the storage rack 12, the biasing members 24, 26 can apply a biasing force in either the vertically upward direction to engage a bottom surface 66 of the container 14, or a vertically downward direction to engage the top surface 64 of the container 14 depending on the location of the biasing members 24, 26.
FIG. 2 illustrates several different arrangements of the biasing members 24, 26 relative to several example storage spaces 70. The uppermost storage space 70 shown in FIG. 2 includes first and second biasing members 24, 26 positioned on a bottom support surface of the top cover 34 of the frame assembly 16. The biasing members 24, 26 extend in a vertically downward direction thereby exerting a vertically downward directed biasing force upon the top surface 64 of the container 14 positioned in the storage space 70.
The middle storage space 70 shown in FIG. 2 includes first and second biasing member 24, 26 positioned on the bottom support surface 42 of the first shelf member 18 and on a top support surface 40 of the second shelf member 20. The biasing members 24, 26 on the bottom support surface 42 of shelf member 18 exert a vertically downward directed biasing force, while the biasing members 24, 26 positioned on the top support surface 40 of the second shelf 20 exert a vertically upward directed biasing force on the bottom surface 66 of the container 14.
The bottom oriented storage space 70 shown in FIG. 2 includes first and second biasing members 24, 26 positioned on the top support surface 40 of the third shelf member 22, thereby exerting a vertically upward directed biasing force on the bottom surface 66 of the container 14.
The biasing forces exerted by the biasing members 24, 26 on a storage container 14 are typically exerted only when the container 14 is inserted into a storage space thereby forcing the biasing members 24, 26 out of a rest state. When the biasing members 24, 26 are forced out of a rest state due to, for example bending of the segments 52, 54 at the bends 56, 58 or flexing of the biasing members 24, 26 along their length between the bends 56, 58, the biasing members 24, 26 attempt to return to their rest state, thereby exerting a biasing force in the opposite direction of movement. In this illustrated configuration of FIG. 2, the biasing force is applied at a point of contact with the container 14. This biasing force can include force components in multiple directions (e.g., XZ, or YZ direction). These biasing force components are preferably sufficient to retain the container 14 within the storage space 70 regardless of the orientation of the storage rack 12. These biasing force components are preferably also sufficient to retain the container 14 within the storage space 70 regardless of the presence of flanges 39, 44, or retaining features of the storage rack 16. For example, if the storage rack 12 shown in FIG. 1 is tipped forward when the containers 14 are inserted in the storage spaces 70, the biasing forces exerted by the biasing members 24, 26 exert biasing forces on the containers 14 to prevent them from sliding out through the front surface openings in the frame assembly 16.
Preferably the biasing members 24, 26 can alone be used to retain the containers 14 within the storage spaces 70. However, it is possible for additional locking or retaining features to be used in combination with the biasing members 24, 26 on the storage rack 12 to further ensure retention of the containers 14 within the storage spaces 70.

Example Biasing Member Configurations of FIGS. 5-10

FIGS. 5-10 illustrate several example biasing member configurations in which the biasing member is formed from the existing shelf member material. Referring first to FIGS. 5-6C, a pair of first and second biasing members 24, 26 is formed from a first shelf member 18. A resulting cutout 25, 27 exists around each of the biasing members 24, 26, respectively. In this way, the biasing member 24, 26 are integral (e.g., formed from the same material and being a unitary piece) with the shelf members 18. The connection portion 50 of the biasing members 24, 26 is coextensive and continuous with the material defining the top and bottom support surfaces 40, 42 of the shelf member 18. FIGS. 6A-C illustrate several example configurations for the biasing members 24, 26 shown in FIG. 5. The biasing members of FIGS. 6A-C include three portions that are bent out of a plane P (see FIGS. 6A) of the top or bottom support surface of the shelf member 18. In other arrangements, the biasing members can include one, two, or more than three segments and include one, two, three (as shown in FIGS. 6A-C), or more bends to define the desired number of segments.
FIG. 6D illustrates one of the biasing members 24 extending from the top surface 40, while the other biasing member 26 extends from the bottom surface 42.
FIGS. 7 and 8A-B illustrate another example biasing member 24 formed from a first shelf member 18. The biasing member 24 as shown in FIGS. 7 and 8A-B includes a greater width. The biasing member 24 of FIGS. 7 and 8A-B is also positioned at a location central across the width W of the shelf member 18. While FIG. 8A illustrates a biasing member 24 having a single bend 56 along the length thereof to define only two segments 50, 52, other configurations including different numbers of bends and segments are possible. FIG. 8B illustrates the biasing member 24 having a contoured portion 51. Other of the biasing member configuration illustrated herein can also include contoured portions.
FIGS. 9 and 10 illustrate a pair of biasing members 24, 26 aligned end-to-end along a length L of the shelf member 18 as opposed to the side-by-side (laterally spaced apart across width W) arrangement of biasing members shown in FIG. 5. FIG. 10 illustrates one of the biasing members 24 extending from one of the top or bottom support surfaces of the shelf member 18, wherein the other biasing member protrudes out from the opposing support surface of the shelf member 18. In other arrangements, both of the biasing members 24, 26 shown in FIGS. 9 and 10 could protrude from the same support surface. Likewise, as with the other biasing member configurations discussed above, each of the biasing members 24, 26 shown in FIGS. 9 and 10 can include different numbers of segments and bends as desired to provide the desired biasing forces and direction of applied biasing force.
In each of the arrangements shown in FIGS. 3-10, the front end F of the shelf member 18 is preferably aligned with the front surface 39 of the storage rack 12. The connection point of each of the biasing members 24, 26 is typically arranged towards the front F of the shelf member 18 so that when a container is inserted into the storage space 70, the free end of the biasing member does not catch on a surface of the container. The biasing member 26 shown in FIGS. 9 and 10 illustrate an alternative arrangement wherein the free end of at least one of the biasing members 24, 26 is oriented towards the front F. The biasing members 24, 26 can include additional bends at or near the free end of the biasing member to reduce the incidence of catching or snagging inadvertently the free end of the biasing member with the container either during inserting or retraction of the container from the storage space 70.
Providing biasing members 24, 26 that are integral with the storage rack 12 can help reduce the total amount of material needed for the storage rack 12 while still providing the desired retention of the containers 14 in the storage spaces 70. A reduction in material can provide a reduced weight for the storage system 10 as well. Integral biasing members 24, 26 typically less likely to detach from the storage rack 12 due to, for example, failure at a connection point to the storage rack 12.

Additional Alternative Configurations

The biasing members disclosed with reference to FIGS. 1-10 are positioned on either the top or bottom support surface 40, 42 of any one of the shelf members 18, 20, 22, or other shelf members of the storage rack 12 shown in FIG. 1. In an alternative arrangement, one or more of the biasing members 24, 26 can be positioned along a side surface 31, 33 of the storage rack 12 to exert a biasing force in the X direction or in the XY plane. In one example, at least one biasing member is integral with one of the first and second side flanges 44, 46 of a shelf member 18, 20, 22 of the storage rack 12. Such an integral biasing member can be defined in the side flange in a similar manner as described above with reference to the biasing members 24, 26 of FIGS. 5-10.
In instances where the side flanges 44, 46 have a relatively small height in the vertical direction, the biasing members can be narrow in width. The side flanges 44, 46 can be increased in height as needed to provide sufficient material for the biasing members to provide the desired biasing force on a container positioned in the storage space 70. Biasing members arranged along the side surface of the storage rack 12 can be used in place of or in addition to biasing members positioned along the top and bottom support surfaces 40, 42 of any given shelf member 18, 20, 22.

CONCLUSION

One aspect of the present disclosure relates to a storage rack that includes a frame assembly, first and second shelf members, and a biasing member. The first and second shelf members are arranged in parallel and are supported by the frame. The shelf members are spaced apart within the frame assembly to define a storage space that is sized to house a container. The biasing member extends from at least one of the first and second shelf members into the storage space. The biasing member is configured to exert a biasing force upon a container housed in the storage space in a direction toward the other of the first and second shelf members to retain the container in the frame assembly. The frame assembly can include four vertically arranged supports, wherein the first and second shelf members are each supported by the four vertically arranged supports. The first shelf member can be positioned vertically above the second shelf member, and the biasing member can be positioned on a vertically upward facing surface or vertically downward facing surface of the second member. The biasing member can be formed integral with one of the first and second shelf members.
