Abstract

The invention relates to pet beds, and particularly with pet beds with a wall and a base encased in a fabric overcoat. Known pet beds have the disadvantage of needing a rimmed section to allow use by e.g., heavy dogs, and the further disadvantage that rimmed sections on walls formed from resilient materials generate high levels of waste. The object of the invention is to avoid this disadvantage, an objective met by a pet bed comprising a peripheral wall formed from a resilient material, the wall having a regular cross-sectional shape that diminishes in width from its upper to lower end.

Description

This invention relates to pet beds.

It is known to form a pet bed with a base and an upstanding peripheral wall attached to the base, and to cover the wall and base separately or collectively with a fabric overcoat. A material particularly suited to use as the base and wall is a resilient polyether or polyester, but other materials can be used and, for ease of manufacture, the base is ordinarily formed as a circular pad of a required depth, and the wall as a rectangular section of a length to surround the base over its circumference, and optionally to provide a section of lowered height and/or remove a short length of wall to provide an access opening to facilitate entry into the bed by the pet for which the bed is intended.

With larger pets, and particularly larger dogs, it is known to provide increased strength in the peripheral wall by having it formed to an approximate mushroom section, to create a rim of a greater cross-section than that of a dependant and integral wall section. The inherent strength of a pet bed with a rimmed wall construction, allows the head of such as a large dog rest on the rim with a reduced risk of the wall totally collapsing.

The problem attendant to such rimmed wall constructions of resilient material is their cost of production, they needing to be cut or machined from rectangular sectioned blocks, a relatively high cost operation, with the generation of considerable volumes of waste material.

The object of the present invention is to provide a pet bed that avoids those disadvantages mentioned above.

According to the present invention, a pet bed comprises a peripheral wall formed from a resilient material, the wall having a regular cross-sectional shape that diminishes in width from its upper to lower end.

Preferably, a base is provided that may be a pad formed from the same resilient material, or a different material, and the base may be integral with the wall or may be separate or attached to the wall by any suitable means such as an appropriate adhesive, detachable connection means, by welding or by sewing.

The resilient material of the wall can be a polyether, or a polyester of a foamed or sponge-like character, or could be formed from fibrous materials. The base may be of the same material, but could be of any other suitable material.

The wall is desirably formed with a section that is of a generally trapezium shape, that may be a regular trapezium with top and bottom parallel faces and equally and oppositely angled side walls, or it may be an irregular trapezium with top and bottom parallel faces, one side wall perpendicular to the end walls and the opposite side wall at an appropriate angle. With an irregular trapezium, the angled wall can form the inside or the outside wall of the bed.

Both forms of construction allow two or more walls to be cut from a single rectangular block of resilient material, by straight cutting of the side walls, be they angularly disposed or perpendicular. As a direct consequence of this, there are considerable reductions in production costs and a notable reduction in the generation of waste material. With the wall positioned with its narrower lower end adjacent the base, the end of widest section is at the top of the wall; the wall is provided with a strength at least equal to that of specially machined shapes used hitherto Whilst the upper surface of the wall may be plain, it can, if desired, be shaped.

The pet bed may be of round or oval shape, but the nature of the material of the wall would permit other bed shapes to be employed, such as square or rectangular.

For the majority of pets, a side wall as is discussed above, has a sufficient inherent strength to reduce substantially the risk of collapse under a load imposed by the pet. However, for certain usages, it may be advisable to have a reinforcing or strengthening member associated with the wall, such as, for example, a strengthening band extending around the walls outer periphery, in whole or in part.

Preferably, the pet bed, walls and base, are encased in a fabric overcoat. When the base and the wall are separate, they may be separately enclosed and a bottom fabric may be attached to the fabric enclosing the wall. Alternatively, both may have a single fabric overcoat to cover at least the exposed surfaces and possibly, also, the bottom of the base pad. Whilst the fabric overcoat may simply enclose the base and/or wall, it is possible to sew the fabric overcoat to at least the wall, the stitch line being spaced from the upper face of the wall, and generate a rim effect, and may be further stitched, such as at the junction of the wall and the base, to provide an attachment between the wall and the base.

Several embodiments of the invention will now be described by way of example only, with reference to the accompanying drawings, in which: [0014]
FIGS. [0015] 1 to 7 are schematic sectional views of possible wall, base and fabric overcoat combinations; where FIG. 1 shows a fabric overcoat stitched to the wall to generate a rim, and FIGS. 2 to 7 show constructions prior to stitching the overcoat to the wall, but which could be left unstitched.
In FIG. 1, a pet bed [0016] 1 has a circumferential side wall 2 formed from an appropriate form stable resilient material such as, for example, a polyether or a polyester of a foamed or sponge-like character. The side wall has a regular cross-sectional shape that diminishes in width from its upper end 3 towards its lower end 4, and the side wall is encased in a fabric overcoat 5, secured to the side wall by stitching as at 6. This not only secures the overcoat in place, but also gives the side wall an aesthetically pleasing appearance, by providing a rim 7 at the top of the side wall.
The bottom of the bed is closed by a [0017] fabric sheet 8 suitably attached to or integral with the fabric overcoat 5, and in the bed bottom there is provided a separate cushion, in the form of a pad 9 of the same material as that of the side wall 2 encased in a fabric outer cover 10 that can be the same as, or can contrast with, the fabric of the overcoat.
FIGS. [0018] 2 to 7 illustrate variants of FIG. 1, and like reference numerals are used for like components. All Figures show the side wall shape as manufactured, and the fabric overcoat on the side walls can be left as illustrated or can be stitched to the side wall as is illustrated in FIG. 1.
In FIG. 2, in place of a loose pad, a secured pad [0019] 9 is provided by having an oversheet 10 of fabric suitably secured to the fabric sheet 8, closing the bottom of the bed.
FIG. 3 shows a form of construction with a separate encased pad [0020] 9, and a removable overcoat 5 on the side wall 2. Thus the fabric of the overcoat to the outer side of the rim can extend across the bottom of the rim to close it, and the fabric to the inner side of the rim also extends across the bottom of the rim, but has a central aperture 11, to allow the fabric overcoat and base to be pulled from the rim 2.
FIG. 4 illustrates a construction with a captive pad [0021] 9 and the fabric sheet 8 closing the bottom of the bed slit and overlapped at 12 after the manner of a pillowcase, to allow the removal of the pad 9, the overcoat having a bottom aperture SA to allow its removal from the side wall.
In FIG. 5 the inner face of the fabric overcoat around the rim is extended across the bottom of the bed to form a [0022] fabric closure sheet 13, and the outer face of the fabric around the rim is similarly extended across the bottom of the bed to form the bottom sheet 8 which is provided with a central aperture 14. A pad 9 is enclosed between the sheets 8 and 13, the aperture 14 allowing the pad to be removed, and the fabric to be removed from the rim. Although not illustrated, the pad can be laid on top of the closure sheet 13, as a separate loose fabric covered cushion.
FIG. 6 again shows a captive pad arrangement, but here the fabric of the inner face of the overcoat has an [0023] envelope 15 attached to it that extends across the bottom of the bed, and encloses the pad 9, and the fabric of the outer face of the overcoat is extended across the base of the bed to form a bottom sheet, with an aperture to allow the fabric and the pad to be removed from the rim.
FIGS. [0024] 1 to 6 illustrate arrangements where the rim and the pad are separate. In FIG. 7, there is illustrated an arrangement where the rim and the pad form a unitary construction, with the rim and pad being formed integrally with each other, or separately formed and attached to each other by an appropriate adhesive or bonding agent, or heat-sealed to each other.
In the forms of construction illustrated, the side wall is formed of a generally trapezium shape, wider towards its upper end to provide reasonable strength at the upper end of the rime and the cross-sectional shape being such that more than one side wall for a bed can be cut from a single block of the material of the side wall, by straight or angled cuts. This provides a considerable reduction in the generation of waste materials, with consequent reductions in cost, but also simplifies noticeably the manner of the production of the side wall by avoiding relatively complex cutting and machining operations, with again a noticeable reduction in costs.
