(12) Referring to FIG. 1 of the drawings, apparatus according to an exemplary embodiment of the present invention comprises a fixed portion 10 and a releasable portion 12. The fixed portion 10 comprises a base 14, which is retained beneath a mattress 16, and has a first part 18 of a clip affixed thereto by means of a length of webbing 20. The releasable portion 12 is detachably affixed to the edge of a bed covering 22, such as a sheet, blanket, bedspread or duvet, and further includes a second part 24 of the above-mentioned clip. It can be seen from FIG. 1 that the first part 18 of the clip comprises the male portion of a front releasing button clip and the second part 24 comprises the corresponding female portion thereof. The first part 18 of the clip consists of an insert member 18a carrying a sprung button member 18b. The second part 24 defines a recess therein (not shown) that generally matches the shape and depth of the insert member 18a. In use, the insert member 18a is fully inserted into the recess of the second part 24 of the clip, such that the sprung button member is depressed and then springs back to exert a force against an internal retaining member. If it is required to release the clip, a user pushes the associated button 24a on the second member to depress the sprung button member 18b of the first part 18, releasing it from the internal retaining member and allowing the insert member 18a to be withdrawn from the recess. Such clips, and others, are well known in the art and will not be described in further detail herein.

(13) Referring to FIGS. 1 and 2 of the drawings, in use, the fixed portion 10 of the apparatus, once installed with the base 14 underneath the mattress 16, remains in situ, whilst the releasable portion 12 can be selectively clipped thereto or released therefrom by means of the first and second parts 18, 24 of the clip, as described above. This means that the bed covering 22 can be selectively anchored to and released from the mattress 16, without the need to repeatedly attach and remove the apparatus to/from the bed. Thus, once configured, the apparatus can remain permanently in situ for repeated and selected use. As shown particularly in FIG. 2, when the two portions 10, 12 are clipped together, the bed covering is prevented from falling or being pulled off the mattress 16, when in use.

(14) Referring now to FIG. 3A of the drawings, the releasable portion 12 of the apparatus is provided with a clamp system for detachably affixing the releasable portion 12 to a bed covering 22. The clamp system comprises a rear grip member 26 and an overhead jaw member 28. The rear grip member 26 comprises an elongate plate which, in use, is oriented substantially vertically and parallel to the side edge of the mattress 16. The overhead jaw member 28 has an inverted, substantially J shaped cross-section, and consists of a lower, slightly curved facia 28b, in opposing and spaced apart arrangement relative to the rear grip member 26, and an upper hooked portion 28a which extends from the opt of the facia, and curves upwardly beyond and towards the inner surface of the rear grip member 26. The hooked portion 28a and the facia 28b are connected together with an extension spring 30 therebetween, such that the relative distance between the lower edge of the hooked portion 28a and the upper edge of the facia 28b can be adjusted, wherein, without any force being applied thereto, the extension spring 30 is configured to hold the above-mentioned edges of the hooked portion and facia together.

(15) The rear grip member 26 and the facia 28 are together by means of a pivot mechanism 32, comprising an elongate arm which is pivotally mounted, at one end, to the rear grip member 26, and pivotally mounted, at the opposing end, to the facia 28 (via an inner mounting plate 28c). The pivot mechanism 32, so arranged and configured, forms an over-centre pivot in respect of the facia relative to the rear gripping member.

(16) In use, and in an open configuration, an opening is defined between the inner surface of the hooked portion 28a of the spring-loaded jaw member and the upper edge of the rear grip member 26. A portion of the edge of a bed covering 22 is inserted into the clamp system via this opening. Next, and referring to FIGS. 3B and 3C of the drawings, a manual force is applied to the lower edge of the facia 28, so as to push it in the direction of the rear grip member 26. This action causes the facia to pivot about the respective adjacent end of the pivot mechanism arm. Simultaneously, the pivot mechanism arm is caused to pivot, in the same direction, at the opposite end. As the rear grip member 26 is effectively fixed, this causes a corresponding downward force to be applied to the facia (and hooked portion 28a) so that the hooked portion moves beyond the upper edge of the rear grip portion 26 (toward the mattress 16) and downward to close the gap between it and the upper edge of the rear grip portion 26 and apply clamping pressure to the bed cover edge located therebetween.

(17) However, the extension spring 30 allows for a certain amount of height adjustment of the hooked portion 28a relative to the facia 28b (defined by the gap 34 therebetween), such that automatic adjustment of the gap between the inner surface of the hooked portion and the upper edge of the rear grip member 26 is effected to allow for varying thicknesses of bed covering. In the fully closed/clamped configuration, as illustrated in FIG. 3 of the drawings, the over-centred pivot mechanism 32 and the spring pressure lock the clamp system in place.

(18) Referring now to FIGS. 4A and 4B of the drawings, the fixed portion 10 of the apparatus comprises a generally T-shaped base 14 consisting of a central elongate leg 14a and a substantially orthogonal cross-bar portion 14b. The upper surface of the cross-bar portion 14b is provided with raised ribs or bumps to form an area 14c of increased friction, such that when the base 14 is placed under a mattress, the frictional engagement between the base and the lower surface of the mattress is maximised. As the free end of the central leg 14a, i.e. the end furthest from the cross-bar portion 14b, there is provided an upstanding end member 14d having an opening 14e defined therein. As described with reference to FIG. 1 of the drawings, the first part 18 of the clip is affixed to the base 14 by means of a length of webbing 20 which is looped through the opening 14e in the end member 14d. Thus, one end of the webbing 20 is fixed to the first part 18 of the clip; the webbing extends through the opening 14e, is folded back on itself and the two opposing portions of the webbing are adjustably attached together in any known manner. The other end of the webbing is free. Thus, the two opposing portions of the webbing can be adjusted relative to each other, in any known manner, to adjust the resultant length of webbing 20 between the first part 18 of the clip and the end member 14d of the base 14. This allows for adjustment to take into account different thicknesses of mattress and also to enable a user to decide how much play to allow in the bed covering, when anchored, according to personal preference and, of course, the extent to which the end of the bed covering extends down the side of the mattress.

(19) It can be seen from FIGS. 5A and 5B that the cross-bar portion 14b of the base 14 may be so dimensioned as to enable its effective use in different positions relative to bed slats 40. However, it will be appreciated that the present invention is not in any way intended to be limited for use with slatted bed frames, but is equally suitable for use with soft or solid mattress bases.

(20) Referring back to FIGS. 4A and 4B of the drawings, each overhanging edge of the cross-bar portion 14b of the base 14 is provided with an open slot 42. The slots 42 are provided to enable additional clips to be employed with the apparatus if required. Thus, referring to FIG. 6 of the drawings, one or more clip members 52 may be employed with the apparatus of an exemplary embodiment of the present invention to prevent the bottom sheet 54 from being pulled off in the night. Each illustrated clip member 52 comprises a length of looped webbing 56 having a folded portion at one end. The webbing 56 is affixed to the base 14 by inserting the loop formed by the folded portion of the webbing into a slot 42, via the opening, such that the open end portions thereof extend into the loop. At the opposite end of the webbing, there is provided a mounting ring 58 to which a clip 60, for example sprung or mechanical, is attached. It will be appreciated that one or more such clips may be selectively employed, as required, and the present invention is not intended to be in any way limited in this regard.

(21) Referring to FIGS. 7A and 7B of the drawings, an additional advantage of the configuration of this exemplary embodiment of the present invention can be seen. Referring first to FIG. 7A of the drawings, in a first configuration, the base 14 is oriented such that the upstanding end member 14d projects upwardly, as in the previous examples. However, in FIG. 7B, it can be seen that the base 14 has been turned over, such that the end member 14d is projecting downwardly. The orientation of the clip part of the apparatus is corrected by inverting the webbing 20 and, as a result, the sitting height of the overall mechanism is significantly shortened for low mattresses, for example. In this case, a high friction/gripping area may be provided on both sides of the cross-bar portion of the base 14.

(22) Referring to FIGS. 8 and 9 of the drawings, in an alternative exemplary embodiment of the present invention, the releasable portion 120 is once again provided with a clamp system for detachably fixing the releasable portion 120 to a bed covering. The clamp system comprises a body portion 260 and an overhead jaw member 280. The body portion 260 comprises an open ended housing 262 defining a receiving channel 262a. The overhead jaw member 280, once again, has an inverted, substantially J-shaped cross-section, and consists of a lower, slightly curved facia 280b and an integral upper hooked portion 280a. The jaw member 280 is pivotally mounted, at opposing side edges, to the housing 262, about a lateral axis thereof, such that the curved facia 280b of the jaw member 280 (at least partially) covers a front face of the housing 262 and the hooked portion 280a thereof, which extends from the top of the facia 280b, is oriented such that it curves generally over (and spaced-apart from) the open end of the housing 262. An end portion 270 is slidably mounted within the receiving channel 262a defined by the housing 262 such that an upper portion thereof extends beyond the upper peripheral edge of the housing 262 defining the channel 262a. The end portion 270 is coupled to the inner walls of the channel and upwardly biased therein (toward the open end thereof) by a pair of springs 272. The upper portion of the end portion 270 (extending beyond the peripheral edge of the housing 262) is provided with a cam member 274, which may be fixed or rotatably mounted, and extends laterally between side edges of the end portion 270. Indeed, the cam member 274 may even be integrally formed with the end portion 270. One or more grooves or ridges 276 may be formed in an outer surface of the cam member 274, wherein a rubber coating (or other frictional material) may be provided. The distal end of the hooked portion 280a of the jaw member 280 may also be provided with a rubber coating 282 (or other frictional material). Indeed, ridges may be provided on the inner surface of the hooked portion 280a and/or its distal end over which, optionally, a rubber (or other frictional) coating may be provided.

(23) In use, as before, in an open configuration, an opening is defined between the distal end of the hooked portion 280a and the upper surface of the cam member 274. A portion of the edge of a bed covering is inserted into the clamp system via this opening. Next, a manual force is applied to the outer surface of the facia 280b, so as to push it towards the adjacent portion of the housing 262. This action causes the facia 280b to pivot relative to the housing 262. The configuration of the coupling between the jaw member 280 and the housing 262, with the pivot point toward a lower end of the facia 280b (i.e. off-centre and further from the hooked portion end than the opposing end), an over-centre locking mechanism is defined. Thus, when the upper part of the facia 280b is pivoted toward the housing 262, the jaw member 280 pivots over-centre and, in the fully closed configuration with no bed covering in situ (as shown in FIG. 9), the hooked portion 280a curves around the upper surface of the cam member 274 with its inner surface in very close proximity thereto. With a portion of bed covering in situ, the locking action will cause the bed covering to become trapped or captured between the distal end/inner surface of the hooked portion 280a and the outer surface of the cam member 274 (with additional grip being provided by the optional rubber coating(s) thereon). The additional thickness of the bed covering between the hooked portion 280a and the cam member 274 causes the hooked portion 280a to generate a downward force (toward the housing 262), pushing the end portion 270 further into the channel 262a defined in the housing 262 (against the spring bias) by a distance corresponding to the thickness of the bed covering. The continued spring bias in the opposite direction to such movement of the end portion 270 (i.e. the spring bias in the direction toward the hooked portion 280a) maintains a strong grip on the bed covering between the cam member 274 and the distal end/inner surface of the hooked portion 280a. To release the bed covering, the user simply pivots the jaw member in the opposite direction, relative to the housing 262, to raise the hooked portion 280a away from the cam member 274 and release the gripping pressure on the bed covering. Thus, The upwardly biased springs 272, when the clamp system is in the closed configuration with a portion of bed covering between the hooked portion 280a and the cam member 274, maintain a grip therebetween on the bed covering by means o compression, which in one exemplary embodiment of the invention, can provide automatic adjustment (for various thicknesses of bed coverings) up to approximately 15 TOG.

(24) In this exemplary embodiment, the base (not shown) may be connected to the clamp system by means of a conventional side release buckle/clip arrangement, wherein a resiliently flexible clip is provided on the base and a buckle 24b is provided at the lower end of the clamp system. To connect the base to the clamp system, the clip is inserted into the buckle, such that a portion 24a of its side edges extends into a respective aperture in the buckle. In order to release the clip (and de-couple the base from the clamp system), a user depresses or squeezes the portions 24a of the clip, thereby releasing it and enabling it to be manually pulled out of the buckle.

(25) Thus, aspects of the present invention provide a device for holding bedclothes on a bed, in use. The device is fully self-adjusting, allowing for varying thicknesses of bed covers to be equally effectively accommodated. All seasons duvet assemblies that usually comprise two duvets releasably connected together for use during the winter months, can be accommodated without the need for a very large clamping system, simply by clamping only one of the duvets, in use. Furthermore, the amount of play in the bed covering, when in use, is fully user selectable, simply by positioning of the device, and (automatic) adjustment of the relative height of the overall device. Any number of devices may be used, although it is envisaged that an equal number of devices will be used on each side of a bed, for example two on each side, but the present invention is not in any way intended to be limited in this regard. The device of aspects of the present invention has additional benefits when used to assist in removing a duvet from, or fitting a duvet to, a duvet cover. If it is required to remove a duvet from its cover, a user can attach a device one each side of the duvet/cover assembly, at the closed end of the duvet cover, clamping only the duvet cover, and simply pull the duvet itself from the open end. When fitting a cover to a duvet, a user again uses two devices at the closed end of the cover, feeds a first corner of the duvet into one corner of the cover and uses a device to clamp the duvet and cover at that corner. The user then feeds the second corner into the corresponding corner of the cover and clamps that corner. Finally, a user can simply pull the rest of the cover over the duvet and secure in the normal manner.

(26) It will be appreciated by a person skilled in the art, from the foregoing description, that modifications and variations can be made to the described embodiments without departing from the scope of the invention as defined by the appended claims.
