A SECURITY DEVICE

Abstract: A security device (10) for retaining a plurality of floor carpet articles in a stack (16) comprises an arm (26) having spikes (28) depending therefrom and support means (17, 18, 21, 23 and 24) for the arm (26) whereby the arm (26) is adapted to be located above the stack (16) and is movable relative to the stack (16) in a direction longitudinally of the spikes (28) towards an upper surface of an upper article (11) of the stack so that the spikes (28) pierce the upper article (11) and retain the upper article (11) on the stack (16).

Description: DESCRIPTION This invention relates to a security device for retaining a plurality of floor carpets in a stack. It is known in the retail trade to stack carpets one on top of another for convenience of storage and for convenience of display. Generally, the procedure is that a prospective purchaser removes a selected carpet from a stack of carpets and the carpet is taken to a station at which sale of the carpet is transacted. A disadvantage of such a system is that there is no provision for discouraging pilfering of carpets. According to the present invention there is provided a security device for retaining a plurality of floor carpet articles in a stack comprising an arm having a spike depending therefrom and support means for the arm whereby the arm is adapted to be located above the stack and is movable relative to the stack in a direction longitudinally of the spike towards an upper surface of an upper article of the stack so that the spike pierces the upper article and retains the upper article on the stack. The arm may be adjustable relative to the support means in a direction longitudinally of the spike. The support means may comprise a plurality of components adapted to co-operate one with another to adjust selectively the height of the arm relative to the stack. The support means may include securing means for restraining relative movement of said components, the securing means being operable to permit said relative movement. The arm may comprise a plurality oi components pivotally connected one to another. The arm may be provided with a plurality of said spikes. The support means may comprise a base for extending under the stack. The support means may also somprise co-operating telescopic members upstanding from the base. Following is a description, by way of example only and with reference to the accompanying drawings, of one method of carrying the invention into effect. In the drawings : FIGURE i is an elevation of one embodiment of a device in accordance with the present invention shown juxtaposition a stack of floor carpet articles, FIGURE 2 is a perspective view of the embodiment shown in Figure 1, FIGURE 3 is an elevation of another embodiment of a device in accordance with the present invention shown juxtaposition a stack of floor carpet articles, and FIGURE 4 is a perspective view of the embodiment shown in Figure 3. Referring now to Figures i and 2 of the drawings, there is shown a device 10 for retaining uppermost carpets li, 12, 13, 14 and 15 of a stack 16 of such carpets. The device 10 comprises a rectangular base plate 17 having a tubular member 18 upstanding thereirom at a location adjacent an edge of the base plate 17. The tubular member 18 is of rectangular transverse cross section and is at an upper portion thereof provided with a stud (not shown extending transversely inwardly of the tubular member 18 and being movable relative to the tubular member 18 in a direction transversely thereof. The stud is included in a locking mechanism 19 having a slot 20 for receiving a key (not shown). The arrangement is such that, when the key is inserted in the slot 20 and is turned, the stud is withdrawn from the bore of the tubular member 18 against a resilient bias. k'hen the key is returned to the original inserted position, the stud is re turned inwardly of the bore of the tubular member 18 due to the resilient bias. The tubular member 18 has located therein an elongate member 21 slidable longitudinally in the tubular member 18 when the stud is withdrawn from the bore of the tubular member 18. The elongate member 21 is provided with a plurality of apertures 22 spaced longitudinally thereof each aperture 22 being adapted to receive an end portion of the stud when the stud extends inwardly of the bore of the tubular member 18 thereby selectively locating the elongate member 21 longitudinally of the tubular member 18. The elongate member 21 is provided, at an end portion thereof remote from the tubular member 18, with an integral sleeve portion 23 having a rectangular bore (not shown). The central longitudinal axis of the bore of the sleeve portion 23 is inclined downwardly towards the base plate 17 and the bore has extending therethrough an elongate carrier 24 of inverted U-shape transverse cross section, the dimensions of the bore of the sleeve portion 23 and the carrier 24, in transverse crosssection, being such that the carrier is movable longitudinally of the bore of the sleeve portion 23. An end portion of the carrier 24 is provided with a stop 25 limiting movement of the carrier 24 longitudinally of the bore of the sleeve portion 23. The carrier 24 has received therein a portion of an elongate arm 26 of substantially rectangular transverse cross-section, the arrangement being such that the arm 26 is pivotally connected midway intermediate opposite end portions thereof by a pin 27. The arm 26 is provided with a plurality of depending needles 28 spaced longitudinally of the arm. In use, a carpet is located on the base 17 and further carpets are stacked one on top of another on the first carpet to provide the stack 16 of carpets. The key is inserted in the slot 20 of the locking mechanism 19 and turned with a result that the stud is withdrawn from the bore of the tubular member 18. The elongate member 21 is inserted longitudinally into the tubular member 18 and lowered therein so that the needles 28 pierce the uppermost carpets 11, 12, 13, 14 and 15 of the stack of carpets 16. The key then is returned to the originally inserted position and withdrawn from the slot 20 of the locking mechanism 19. In consequence, the stud is released and is urged by the resilient bias towards the elongate member 21. The arm 26 is moved downwardly so that the elongate member 21 moves relative to the tubular member 18 until the stud snaps into engagement with an aperture 22 in the elongate member 21. The arm 26 thus is restrained from being lifted upwardly from the stack of carpets 16 and each of the carpets li, 12, 13, 14 and 15 is restrained from being moved relative one to another due to the needles 28 extending therethrough. The weight of the uppermost carpets li, 12, 13, 14 and 15 on the remaining carpets in the stack 16 is such that the carpets 11 to 15 inclusive generally cannot be lifted to remove carpets of the stack 16 located below the lowermost carpet 15. In order to remove any one of the carpets comprising the stack 16, it is necessary to insert the key (which normally would be in the possession of a person of authority) into the slot 20 of the locking mechanism 19 and to effect turning of the key in order to operate the locking mechanism and lift the carrier 24 and, in consequence, the arm 26 and needles 28 from the stack of carpets 16. In this manner, pilferage of carpets from the stack is substantially reduced. It will be appreciated that the needles 28 are standard and cause no damage to carpets. Furthermore, it will be appreciated that the needles 28 may be removably attached to the arm 26. It will also be appreciated that, in the case of aged carpets which, when arranged in stack result in at least upper carpets of the stack extending in curved configuration, the apparatus in accordance with the present invention compensates for such curvature due to the pivotable connection of the arm 26 and the carrier 24. Referring now to Figures 3 and 4 of the drawings, there is shown a device 29 similar to the device iO except that, in the device 29, an arm 30 is provided with an integral disc 31 at an outer end portion thereof, the plane of the disc extending substantially parallel to the plane of carpets in a stack 16, and an opposite end portion there of is integral with a depending elongate member 32 corresponding to the elongate member 21 of the device 10. The disc is provided with depending needles 33. In all other respects the device 29 corresponds with the device 10.
