Electronic article surveillance marker assembly

Abstract

An EAS marker assembly comprises a housing defining a cavity extending inwardly from an open wall of the housing and a passage extending through a closed wall of the housing opposite the open wall and disposed aside the cavity and an EAS marker secured to the closed wall of the housing. A securement member extends through the passage and secures the EAS marker assembly to an article of manufacture, the article of manufacture closing the open wall of the housing.

Description

FIELD OF THE INVENTION

This invention relates generally to security from shoplifting of articles of manufacture and pertains more particularly to electronic article surveillance marker assemblies for use with articles of manufacture.

BACKGROUND OF THE INVENTION

One form of electronic article surveillance (EAS) marker in widespread use is in the form of a flat, thin, flexible, rectangular member which is applied adhesively to flat or curved exterior surfaces of articles. One shortcoming of such exterior surface application is that, while often covered by a bar code label, the presence of the EAS marker nonetheless is evident since it is visible from the sides of the bar code label. Still further, the EAS marker is accessible to a customer.

Commonly-assigned U.S. Pat. No. 5,945,909 discloses a so-called “seal” comprising a one-piece body having first and second members closable one upon the other and thereupon respectively defining first and second outer seal walls and a tail peripherally continuous with at least one of the first and second members at a third outer seal wall the tail having a hook at a free end thereof. The seal body defines an interior recess and a detent opening into said third outer seal wall for retentive reception of the tail hook interiorly of the seal. An EAS marker is disposed in the seal body recess and is contained therein between the first and second outer seal walls upon closure of the first and second members.

The '909 patent seal is used by circumscribing a portion of an article, e.g., a watchband, with the tail and then inserting the tail hook into the seal body detent.

The EAS marker is a flat ferromagnetic strip member and is detectable by various known EAS systems, e.g., where the marker is not deactivated (as at an article payment checkout counter) and is carried through EAS marker detection gates at a facility exit.

The above first-discussed practice of applying the EAS marker to the exterior of an article of manufacture, despite its noted disadvantage, has advantage over the EAS marker hidden embodiment of the '909 patent in that the supplier of the EAS marker-equipped article of manufacture has clear awareness that the article is EAS marker-protected. Thus, the EAS marker assembly of the '909 patent is not inspectable as to the presence or absence of the EAS marker or as to its condition, i.e., intact or not intact.

SUMMARY OF THE INVENTION

The present invention has as its primary object the provision of an EAS marker assembly which overcomes the above-discussed disadvantages of known EAS marker practices.

A more particular object of the invention is to provide an EAS marker assembly which may be applied to articles of manufacture wherein deactivation of the EAS marker is not adversely affected by the composition of the article of manufacture.

In attaining the first mentioned object, the invention provides an EAS marker assembly comprising a housing defining a cavity extending inwardly from an open wall of the housing and a passage extending through a closed wall of the housing opposite the open wall and disposed aside the cavity and an EAS marker secured to the closed wall of the housing.

In another aspect, the invention provides, in combination, an article of manufacture, an EAS marker assembly comprising a housing defining a cavity extending inwardly from an open wall of the housing and a passage extending through a closed wall of the housing opposite the open wall and disposed aside the cavity and an EAS marker secured to the closed wall of the housing and a securement member extending through the passage and securing the EAS marker assembly to the article of manufacture, the article of manufacture closing the open wall of the housing.

In attaining the above-noted more particular object, the invention provides an article of manufacture, an EAS marker assembly comprising a housing defining an interior compartment and a passage extending through the housing and an EAS marker secured to a wall of the housing and a securement member extending through the passage and securing the EAS marker assembly to the article of manufacture, the housing being of a dimension such that the article of manufacture does not interfere with deactivation of the EAS marker.

The invention will be further understood from consideration of the following description of preferred embodiments thereof and from the drawings where like reference numerals identify like parts throughout.

DESCRIPTION OF THE DRAWINGS

FIG. 1 is a front elevation of an EAS marker housing in accordance with the invention.

FIG. 2 is a right side elevation of the FIG. 1 housing.

FIG. 3 is a left side elevation of the FIG. 1 housing.

FIG. 4 is a bottom plan view of the FIG. 1 housing.

FIG. 5 is a top plan view of the FIG. 1 housing.

FIG. 6 is a front elevation of an EAS marker assembly secure to an article of manufacture shown in part.

FIG. 7 is a sectional view as would be seen from plane VII—VII of FIG. 6.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1–5, housing 10 is a one-piece plastic body having a top wall comprised of first portion 12a and second portion 12b at respective different elevations and side walls 14, 16, 18 and 20. Housing 10 is open at its bottom wall and cavity 22 extends upwardly from such open bottom wall to top wall first portion 12a.

Housing 10 further defines a passage 24 opening into top wall second portion 12b and extending through the housing into registry with the housing open bottom. Passage 24 is bounded by interior housing structure 26 extending from the open wall to the closed wall and of cylindrical cross-section.

Turning to FIGS. 6 and 7, EAS marker assembly 28 is shown secured to article of manufacture 30 by screw fastener 32, which extends through passage 24, abutting on top wall second portion 12b and being threaded into article of manufacture 30. EAS marker 34 is adhesively secured to the undersurface of top wall first portion 12a.

Article of manufacture 30, e.g., an automobile stereo, will be seen to close the open bottom wall of housing 10. Thus, the invention provides an EAS marker assembly, the EAS marker of which is viewable prior to assembly with an article of manufacture and is hidden from view upon completion of the assembly.

In the above-noted example of an article of manufacture, the housing thereof is a metal and thus capable of interfering with deactivation of the EAS marker, which may be an Ultra*Strip III EAS marker, available from Sensormatic Electronics Corporation and deactivatable by a magnetic field to which it is exposed at article checkout. In accordance with the invention, housing 10 is of a dimension, i.e., height, such that EAS marker 34 is spaced from article of manufacture 30 by a distance D (FIG. 7). In the case of usage of the cited Sensormatic EAS marker, such spacing is at least one-quarter of an inch.

Various changes may be introduced in the disclosed preferred embodiment without departing from the invention. Accordingly, it is to be appreciated that the true spirit and scope of the invention is set forth in the following claims.
