DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, there is shown a perspective view of a shelf locking system 10 incorporating features of the present invention. Although the present invention will be described with reference to the exemplary embodiment shown in the drawings, it should be understood that the present invention can be embodied in many alternate forms of embodiments. In addition, any suitable size, shape or type of elements or materials could be used.
The shelf locking system 10 includes a shelf support 12 and a removable shelf lock 14. The shelf lock 14 is removably engageable with the shelf support 12. The shelf lock 14 and the shelf support 12 provide for an improved shelf locking system 10 which secures and protects cabinet shelf parts/components while being shipped.
Referring now also to FIGS. 2-4, the shelf support 12 comprises a support body section 16, and a pin member 18. The pin member 18 is configured to be insertable into a cabinet wall 20. The support body section 16 comprises a contact surface, or first surface, 22 (further illustrated in FIGS. 3 and 4) which is configured to be in contact with a shelf 24. The shelf support 12 supports the shelf 24 at a first side, or bottom side, 26. The shelf support also comprises a latch portion, or first portion, 28 (best shown in FIG. 4). The latch portion 28 extends from an end, or first end, 30 of the support body section 16 to the pin member 18. The latch portion 28 may comprise a cylindrical shape with a cylindrical outer surface 32. The shelf support 12 may be comprised from plastic and/or metal, or any other suitable material. Additionally, the shelf support may be a one-piece or a two-piece member.
The shelf lock 14 comprises a body section 34, two contact members 36a, 36b and two arm members 38a, 38b (best illustrated in FIGS. 3 and 4). The shelf lock 14 is a one-piece member which may be formed from plastic for example. The two contact members 36a, 36b extend from a middle portion 40 of the body section 34. The two contact members 36a, 36b have a suitable length for contacting a top side, or second side, 42 of the shelf 24. Additionally, the two contact members 36a, 36b may extend in a general curvilinear fashion such that the two contact members 36a, 36b curve away from one another. However, it should be noted that contact members having any suitable shape for contacting the shelf may be provided.
The two arm members 38a, 38b extend from a first lateral side 44 of the body section 34. The two arm members 38a, 38b extend in generally the same direction (a direction away from a bottom side 46 of the body section 34) as the two contact members 36a, 36b. Additionally, the orientation of the arm members 38a, 38b to the contact members 36a, 36b may be provided such that a width 48 of the arm members 38a, 38b is generally perpendicularly oriented relative to a width 50 of the contact members 36a, 36b (see FIG. 1). The two arm members 38a, 38b extend from the first lateral side 44 and form a common arm member section 52 before extending as two separate arm members. The two arm members 38a, 38b extend from the common arm member section 52 with suitable dimensions to allow for a slotted opening 54 between the two arm members 38a, 38b. One of the arm members, which may also be referred to as a latch arm member, 38a comprises a contoured end 56 which extends towards the other arm member 38b to form a substantially closed end 58 of the slotted opening 54. Additionally, an inner edge of the contoured end 56 provides a latch contact area 60 and an outer edge may provide a lead-in feature 62 to facilitate reception of the latch portion 28. It should be noted that one or both of the arm members 38a, 38b may be resiliently deflectable to allow for receiving the latch portion 28 of the shelf support 12. The two arm members 38a, 38b have a suitable length for extending beyond the shelf 24 and allowing for engagement with the shelf support 12.
It should be noted that although the arm members 38a, 38b are joined proximate the body section 34, the arm members 38a, 38b may extend separately from the lateral side 44. Additionally, although the figures illustrate the arm member 38a comprising the contoured end 56 and the latch contact area 60, an alternate embodiment may provide the reverse configuration such that the arm member 38b comprises the contoured end and the latch contact area. Further, another alternate embodiment may provide arm members (having contoured ends and latch contact areas) that are substantially mirror images of each other.
The shelf lock 14 removably attaches to the shelf support 12 as illustrated in FIGS. 5-7. To engage the shelf lock 14 with the shelf support 12, the shelf lock 14 is positioned such that the arm members 38a, 38b extend between the cabinet wall 20 (not shown in FIGS. 5-7 for purposes of clarity) and an end 64 of the cabinet shelf 24. The two extending arms 38a, 38b are then aligned with the shelf support 12 wherein the slotted opening 54 is oriented opposite the latch portion 28 (see FIG. 5). To attach the shelf lock 14 to the shelf support 12, the shelf lock 14 is advanced in a direction (represented by arrow 55) towards the shelf support 12 wherein the latch portion 28 is received between the arm members 38a, 38b. One or both of the arm members 38a, 38b resiliently deflect to separate the arm members and open the substantially closed end 58 of the slotted opening 54 (see FIG. 6). The lead-in feature 62 facilitates the deflection of the arm member(s) 38a, 38b and guides the latch portion 28 towards the slotted opening 54. As shown in FIG. 7, the shelf lock 14 is then fully advanced until the latch portion 28 is within the slotted opening 54 and the contact members 36a, 36b are against the second side 42 of the shelf 24. The arm members 38a, 38b resiliently deflect back towards each other to form the substantially closed end 58 of the slotted opening 54. This retains the shelf lock 14 engaged with the shelf support 12 as the latch contact area 60 is fitted against the latch surface 32. It should be understood that although the figures illustrate the latch portion 28 as having a greater diameter than the pin 18, alternate embodiments may comprise latch portions having a diameter equal to or less than the pin diameter.
When the shelf lock 14 and the shelf support 12 are joined together and sandwich the cabinet shelf 24 (shelf support contact surface 22 on a first side 26 and contact members 36a, 36b on a second side 42), they secure the shelf 24 for protection during shipping. The shelf support 12 and the shelf lock 14 provide a clamping force to the shelf 24 such that the shelf 24 does not move relative to the cabinet wall 20. Once the cabinets are installed, the shelf lock 14 can be separated and removed from the shelf support 12. The removable shelf lock 14 can be discarded. The shelf support 12 remains in the cabinet to support the cabinet shelf 24.
The removable shelf lock 14 may be installed in one of two positions as illustrated in FIGS. 8-9. The removable shelf lock 14 may be mounted on the top side 42 of the shelf to hold the shelf 24 down (see FIG. 8). This configuration allows both contact members 36a, 36b to support the second side (or top side) 42 of the shelf 24. This configuration may be utilized when it is desired to restrain the shelf 24 from translating in a vertical direction (direction perpendicular to the second side 42) during shipping and/or handling. Additionally, the contact members 36a, 36b may provide a friction force (or clamping force) to the top side 42 of the shelf 24 to secure the shelf 24 in a horizontal direction.
The removable shelf lock may also be mounted on a front edge, or third side, 66 of the shelf 24 to hold the shelf 24 down and in (see FIG. 9). This configuration allows the first contact member 36a to support the third side 66 of the shelf 24 and the second contact member 36b to support the second side 42. This configuration may be utilized when it is desired to restrain the shelf 24 from translating in a vertical direction and a horizontal direction during shipping and/or handling.
In both of the positions described above, the direction of a holding force (represented by arrows 68, 70) generated between the removable shelf lock 14 and the shelf support 12 is generally in line with an installation direction (represented by arrows 72, 74) of the shelf lock 14 to the shelf support 12 (except opposite). The opposite directions of the holding force 68, 70 and the installation direction 72, 74 provide for a holding force that is not generated perpendicular to the installation direction. For example in the first position (FIG. 8), the holding force 68 is generated in a direction opposite to the installation direction 72. The holding force 68 is not generated in a direction perpendicular to the installation direction 72 (or parallel to the top side 42 of the shelf 24). Similarly, in the second position (FIG. 9), the holding force 70 is generated in a direction opposite to the installation direction 74. The holding force 70 is not generated in a direction perpendicular to the installation direction 74.
It should be understood that although the figures illustrate the latch portion 28 as having a cylindrical shape, any suitable shape for providing a latching surface and latching engagement may be provided. It should also be understood that although the figures illustrate the shelf lock 14 as engaging with the latching surface 32 of the shelf support 12, in an alternate embodiment, the shelf lock may engage a portion of the pin member.
It should be understood that the foregoing description is only illustrative of the invention. Various alternatives and modifications can be devised by those skilled in the art without departing from the invention. Accordingly, the present invention is intended to embrace all such alternatives, modifications and variances which fall within the scope of the appended claims.
