Abstract
Abstract A signal-emitting arrangement adapted for non-destructive attachment to a valuable garment, such as a fur coat, is described. A pair of large-area plates are hinged together along corresponding longitudinal edges thereof, one of the plates bearing a signal transmitter. A plurality of corresponding projections and recesses are arranged along the other longitudinal edges of the respective plates so that when such plates are pivoted toward each other with the edge of the garment therebetween, the projections pierce the garment and enter the recesses. The projections and recesses are distributed over the longitudinal edge in staggered fashion to avoid undue force concentration on, and distortion and buckling of, the garment edge. A pair of separate camming projections disposed on one of the plates outside the garment-piercing area of the other projections is releasably lockable in separate aligned recesses on the other plate. For this purpose, suitable blocking members are resiliently biased into such recesses in the path of movement of the camming projections, which have sawtooth-like formations thereon for initially displacing and then releasing the blocking elements to lock the camming projection in the associated recesses when the first set of garment-piercing projections penetrate their recesses.

In an apparatus for signalling a removal of a garment from an area provided with a sensing element, first and second elongated plates having corresponding first and second longitudinal edges, one of the plates having signal-transmitting means for emitting an indication detectable by the sensing element when the garment is moved past the sensing element with the one plate affixed to the garment, means joining the respective first longitudinal edges of the first and second plates for pivotal movement between a first closed position in which corresponding first surfaces of the plates are disposed in confronting relation for engaging a portion of the garment and a second closed position in which the first surfaces are disengaged from the garment, the first plate having a plurality of first recesses disposed in the first surface thereof and distributed along the second longitudinal edge thereof, the second plate having a correspondingly distributed plurality of first garment-piercing projections extending outwardly from the first surface thereof for penetraing the garment portion and entering the first recesses of the first plate when the plates are pivoted into their first position, the first plate having a pair of longitudinally spaced second recesses disposed on its first surface, the second recesses being situated in transversely spaced relation to the first recesses; and in which the apparatus further comprises, in combination, a pair of second locking projections individually extending from the first surface of the second plate in aligned relation with the second recesses of the second plate when the plates are brought into the first position, the second projections individually extending into the respective second recesses when the first projections extend into the first recesses, and means for releasably locking the second projections in the associated second recesses.
Claim 3
Dependent Claim
152 words
Apparatus as defined in claim 1, in which the first plate includes means defining a third recess extending longitudinally therein in alignment with and intersecting relation to the respective second recesses; and in which the releasable locking means comprises, in combination, a substantially U-shaped blocking element having first and second outer legs longitudinally spaced by approximately the longitudinal distance between the second recesses for selectably blocking the second recesses, the blocking element being supported for longitudinal movement in the third recess between a locking position in which the first and second legs thereof individually extend into corresponding regions of the respective second recesses in the paths of movement of the associated second projections on the second plate and a release position in which the first and second legs are withdrawn from the associated second recesses, and spring means supported in the third recess for biasing the blocking element into its locking position.
Claim 4
Dependent Claim
82 words
Apparatus as defined in claim 2, in which the releasable locking means further comprises, in combination, a sawtooth-shaped formation on the outer surface of each second projection for successively outwardly camming the associated leg of the blocking element toward its release position against the force of the spring means and then releasing said leg so that such leg is urged back by the spring means to its locking position behind the formation to secure the second projection within the associated second recess.
Claim 5
Dependent Claim
202 words
Apparatus as defined in claim 1, in which the first plate comprises means defining a third recess extending longitudinally therein in alignment with and intersecting relation to the respective second recesses; and in which the releasable locking means comprises, in combination, first and second substantially U-shaped blocking elements each having first and second outer legs longitudinally spaced approximately by the longitudinal distance between the second recesses, the first and second blocking elements being supported in transversely spaced relation with their respective legs extending toward each other, the first and second blocking elements being longitudinally staggered whereby the first leg of the first element is disposed between the first and second legs of the second element, each of the first and second elements being supported for longitudinal movement in the third recess between a locking position in which the associated first and second legs individually extend into corresponding regions of the respective second recesses in the paths of movement of the associated second projections on the second plates and a release position in which the first and second legs are withdrawn from the associated second recesses, and spring means for simultaneously urging the first and second blocking elements into their respective locking positions.
Claim 6
Dependent Claim
34 words
Apparatus as defined in claim 4, in which the spring means comprises a compression spring extending between the first leg of the first blocking element and the second leg of the second blocking element.
Claim 7
Dependent Claim
99 words
Apparatus as defined in claim 4, in which the releasable locking means further comprises a pair of sawtooth-shaped formations extending radially symmetrically from opposite sides of the outer end of each second projection for engaging and successively outwardly camming the corresponding legs of the first and second blocking elements within the associated second recess toward their release position against the force of the spring means and then releasing both such corresponding legs so that such legs are again simultaneously urged back into their locking position behind the associated formations to secure the second projection within the associated second recess.
