This application claims the benefit of U.S. Provisional Application No. 60/841,483 Filed Aug. 31, 2006.
BACKGROUND OF THE INVENTIONThe present invention relates to a crown sizer and, more particularly, to a crow%,n sizer with a locking mechanism for mounting about the post of a metal hook hanger.
Various types of hangers are used in the retail industries. One such hanger is formed from a plastic body having a threaded post on its upper edge. A metal hook is threaded into this post to provide what is commonly referred to as a metal hook hanger.
Although size indicators are commonly used with plastic hook hangers (i.e., a hanger having both a plastic body and plastic hook), the use of size indicators on metal hook hangers has proven more challenging. One such size indicator available for metal hook hangers is referred to as a crown sizer, and is disclosed in U.S. Publication No. 2006/0006204 A1. The sizers disclosed in this publication are intended to be passed over the metal hook and “snapped” into position about the post of the hanger. These sizers, however, have several shortcomings. For example the ability of such crown sizers to remain engaged with the hanger varies from hanger to hanger due to differences in design and tolerances between the various manufacturers. Moreover, certain of these sizers are designed for easier installation, which tends to make the engagement less permanent and prone to unwanted disassembly. Finally, the more elaborate designs present manufacturing challenges, as well as issues with both the installation and retention of the sizer on the hanger.
There is therefore a need in the art for a crown sizer which is more easily manufactured, which can be readily installed about the post of a metal hook hanger, and which will remain securely engaged to the hanger.
SUMMARY OF THE INVENTIONThe present invention, which addresses the needs of the prior art, relates to a sizer for mounting to a post of a hanger. The sizer includes a body configured to surround at least a portion of the post. The body is formed with a split-wall construction to allow expansion of the body during installation of the body about the post. The body further includes a locking mechanism for locking the boded into a closed position following installation about the post.
In one preferred embodiment, the locking mechanism includes cooperating interfitting structure located on a sidewall of the sizer body. In a still further preferred embodiment, the cooperating interfitting structure includes a groove disposed on a first edge of the sidewall and a rib disposed on a second edge of the sidewall, wherein the rib is configured to engage the groove when the body is locked into the closed position.
The present invention further relates to the combination of a hanger and a sizer. The hanger includes a hanger body, a hook-receiving post extending from the hanger body, and a pair of struts connected to the hanger body and located on opposing sides of the posts. The posts and struts define at least one engagement cavity. The sizer includes a sizer body configured to surround at least a portion of the post. The sizer body is Conned with a split-wall construction to allow expansion of the sizer body during installation of the sizer body about the post. The sizer body further includes a locking mechanism for locking the sizer body into a closed position following installation about the post.
As a result, the present invention provides a sizer which can be easily and cost effectively manufactured, which can be readily installed about the post of a metal hook hanger without requiring excessive force, and which will remain securely engaged to the hanger during usage.
Referring to
Those skilled in the art will recognize that a sizer must be both 1) easily securable to the hanger, and 2) capable of remaining secured to the hanger during normal usage (i.e., the sizer should remain on the hanger in a child proof manner). As discussed above, the prior art has been unable to provide a crown sizer for a metal hook which meets both of these criteria. In contrast, the sizers of the present invention are capable of being easily mounted about the post of a metal hook hanger and of remaining secured to the hanger during normal usage.
The sizers of the present invention fulfill these dual goals through the unique configuration of such sizers. More particularly, the sizers of the present invention, e.g., sizer 10, are formed with a split-wall construction which defines an opening 24 in one wall of the sizer. The split-wall construction configuration allows the sizer to be easily installed over hook 16 (see
In addition, it has been discovered herein that the split-wall construction allows tabs 30 to be configured to more closely match and to more fully engage cavities 22, which results in a more secure attachment between the sizer and the hanger. Moreover, the split-wall construction allows the wall thicknesses of the sizer to be increased for enhanced rigidity. In contrast, the prior art crown sizers which lack the novel split-wall construction of the present sizers must be forced over and into engagement with the post of the hanger. Those skilled in the art will appreciate that this prior art design necessarily limits the extent to which the interior protrusions can engage the cavities formed aside the post, or any other such cavity formed on the post. It also limits the ability to increase the rigidity of the sizer.
