This application is a continuation-in-part of application Ser. No. 178,082, filed Sept. 7, 1971, now abandoned.

This invention relates to a device for adapting a rug rake so that it may be converted to a brush as and when desired, and to means for rendering a fabric type ofv brush suitable for brushing or sweeping rugs.

It is an object of the invention to provide an adaptor for a rug rake, which adaptor mounts a brushing surface and which adaptor is detachably attachable to the rug rake.

It is an object of the invention to provide means for adapting a slant pile fabric, known for use as a brush, to use as a device for brushing or sweeping rugs.

In the drawings which illustrate a preferred embodiment of the invention:

FIG. 1 shows a perspective, partially broken away, view of the invention;

FIG. 2 shows a cross-section along the line 2-2 of FIG. 1;

FIG. 3 shows a partial cross-section along the lines 33 of FIG. 1;

FIG. 4 shows a partial cross-section along the lines 44 of FIG. 1;

FIG. 5 shows a partial side view along the lines 55 of FIG. 1; and

FIG. 6 shows a bottom view of the adaptor with the rug rake installed.

In the drawings, the rake comprises a body 10 preferably of flat longitudinally extending slightly bowed form. An array of tines 12 (here about 33) suitable for raising the fibres on a shag rug, are provided projecting from one side of the body, in roughly the same direction, to contact the rug surface. The body member, on the opposite side from the tines, provides a sloping mount 14 for a manual operating handle. In the preferred embodiment, the mount 14 contains a threaded socket, not shown, into which the handle may be screwed to extend at 45 to a floor, when the tines 12 are in contact with a rug on said floor. As alternatives to the threaded mount, and within the scope of the invention, other means of attachment of the handle may be provided, and other manual grasping means may be provided for manually using the array on a rug. In the preferred embodiment, the handle mount 14 is a separate member glued and/or bolted to the body. However, these members may be made intergral, or separately and capable of being assembled in a different manner, as desired.

The surface 16 of body member 10 from which the tines extend, is provided with a pair of an outer and an inner peripheral flange, defining between them a groove 21 to receive an edge of the adaptor as hereinafter described. Preferably each time adjacent flange 19 is provided with a tin 23 outwardly sloping from the root of the tine and dimensioned and contoured to direct the adaptor edge striking said fln into the groove 21.

The invention is directed to the combination of the rub rake, so far described, with an adaptor to convert the rake into a brush and with the provision of slides on the brush extending generally in the brushing direction to assist in the operation of the latter.

The body member 10 at a plurality of locations (here four) adacent said flange 18 is provided with slots immediately adjacent flanges 19 and approximately parallel to the direction of longitudinal extension of the adjacent flanges 18 and 19. The four slots are arranged in opposed pairs, the pairs being preferably symmetrically disposed on each side of the handle-mount l4. Slots 20 extend through the wall 15 to surface 16.

' The adaptor comprises a brush support member 22, preferably of plastic, shaped to overlie the array of tines 12 and here embodied as a solid wall or plate and provided with a brush surface on one side, and having resilient and slightly flexible side walls 24 extending from brush support member 22 in the opposite direction to that faced by said brush surface.

The edge 25 of said adaptor side walls, remote from said wall, is shaped to be received in the groove 21 when the adaptor is mounted on the brush body. The adaptor is also provided with a plurality (here four) of flat prongs 26 inset from the adaptor sidewalls 24 and located and of a length so that they may be directed through slots 20 in the rug rake body wall. The flat prongs 26 are, adjacent their free ends, provided with outwardly directed hook or shoulder members having shoulders 28 designed to contact the rug rake body wall 15 on the side thereof remote from the tines, when the prongs 26 are extending through the slots and in such arrangement, to hold the adaptor in position with the edge of the adaptor side walls 24 received in the groove 21.

To attach the adaptor to the rug rake body, the side walls 24 are slid about the tines l2 and the prongs 26 directed into slots 20. The outwardly directed fins guide the edge of wall 24 into groove 21. The edge presence in the grooves and the engagement of shoulders 28 holds the adaptor in place in the rug rake body. This is assisted by the provision of ribs 23A (FIG. 4) projecting from the wall 25 of brush body 10 toward the tines 12 and arranged to frictionally'contact adjacent tines 12.

To dismantle the adaptor from the rug rake body the walls 24 thereof and/or prongs 26 are pressed inward to disengage the shoulders 28 from wall 15 after which the adaptor may be slid away from the body. Detachably mounted on handle 14 is a small brush, as shown, which may be used to clean the main brush.

The brush surface is formed from a suitably cut pile fabric 33, produced by synthetic fibre strings (preferably nylon) woven through a fabric matrix or backing, preferably cotton, to provide at the intended front of the fabric, nylon (or other synthetic fibre) extents between stitch apertures which are double the pile length required. These extents are then cut to produce the piles and these are panned which involves the applica tion of a heated surface to the piles in one sense to produce the required slant. With such panning the fibres forming the bristles, slope predominately in one direction, and the brush is used by brushing in the direction wherein the bristles so predominately sloped are advanced, i.e. in which the bristle tips lead the roots. The advance or brushing direction is to the left in FIG. 2 and to the left and rearwardly in FIG. 1, as shown by the slope of the bristles and is, for the assistance of the user indicated by the arrow 31 in FIG. 1.

Inter alia the bristle pile fabric may be obtained through Collins and Aikman Corporation, Ca-vel Division, Ca-vel, North Carolina, USA. 27112.

The pile fabric 33 may be attached to the support 22 in any desired manner. As shown in FIGS. 2 and 4 the fabric 33 suitably shaped by spongy or rubber padding 32 may be retained and supported between outer peripheral flanges 34 extending outwardly from the sup port 22 and an inner member 36 having outwardly directed and pointed tines 38, shaped to contact the inner surface of flange 34 after piercing fabric 33 and padding 32 thus retaining the padding 32 and fabric 33 in position.

It is found, in accord with the invention, that the operation of the brush on the rug requires slides overlying, at spaced locations, the fabric, for contacting the rug to be brushed with the slides directed in the desired brushing direction, determined by the advanced direction of the bristles. It is believed that the reason is that the slides limit the engagement of the bristles with the rug to a suitable amount of interference and also guide the brush, relative to the rug, in the brushing direction.

Slides 35 preferably of 3/16 inch thick plastic, including the preferably provided ribs 37, are attached over the fabric preferably at two spaced locations, to contact the rug surface during brushing. The slides 35 extend longitudinally in their rug contacting extent in a direction having its major component parallel to the direction of brushing as directed by the advanced direction of the bristles and indicated by the arrow. Preferably such slides extend parallel to the extended brushing direction. Preferably a plurality (here 4) of ribs 37 project from slide 35 toward the intended rug position and are directed in the direction of longitudinally extending slides 35, to be preferably parallel to the brushing direction and to guide the direction of the rug rake in such direction. The ribs 37 are preferably downwardly pointed.

The slides 35 are mounted on the body 22 in any desired manner, such as by gluing or clamping and are climensioned to compress the spongy material 32 under the fabric which they overlie.
