Definitions

  • a broom construction includes two shell portions which are fitted together by aligning and interengaging projections on one portion into recesses on another and they are held together by a snap fit of a projection of one portion into a female receiving portion on the other.
  • the shell portions together define a socket for receiving a handle at one end and a recess or skirt portion for receiving a bundle of fibers in the opposite end.
  • the fibers are held in position by projecting teeth which are defined in two separate longitudinally spaced rows within the skirt portion, the rows of teeth being offset so as to engage the fibers in a manner such that they can fan out.
  • the assembly is either locked by an encircling collar extending over the socket portion of the shells or by C-shaped securing clips which fit into recesses defined on each end of the shells or by a combination of both, and in some instances, by the addition of an encircling band around the exterior of the skirt portions.
  • This invention relates to a broom or similar brush-wear article wherein a bundle or pack of bristles, fibres, or strands is maintained between two assembled mating shells.
  • the present invention aims at providing such shells having a configuration which allows the broom to be assembled easily and rapidly, while the pack of bristles is maintained after assembling under optimum conditions as far as tightness and firm grip are concerned, in spite of the stresses acting on the broom when used.
  • Yet another object of the invention is to provide a broom wherein the bundle of bristles is efficiently maintained between the assembled half-shells due to the provision of rows of teeth or wedges in the skirt of said half-shells, which teeth or wedges penetrate the fibre bundle.
  • FIG. 1 is an elevational view of a broom according to the invention, with several parts torn away.
  • FIG. 2 is a perspective view showing one of the halfshells used in manufacturing such broom.
  • FIG. 3 is a perspective view showing a collar for maintaining the portions of the half-shell which constitute a socket adapted to receive the broomstick.
  • FIG. 4 is an axial cross-sectional view of the broom of FIG. 1.
  • FIG. 5 is a perspective view corresponding to FIG. 2, showing another embodiment of the invention.
  • FIG. 6 is an axial cross-sectional view of the broom of FIG. 5.
  • FIG. 7 is a sectional broom of the clamping arrangement for assembling the sides of the half-shell according to FIG. 5.
  • FIGS. 8 and 9 are sectional views showing the interlocking feature of the half-shells.
  • FIG. 10 is a diagrammatic view showing the arrangement of a bundle of fibres assembled prior to assembling the half-shells.
  • the broom comprises a bundle 1 of rice-straw, sorghum, or similar fibres, or bristles, maintained between two half-shells which, when assembled, form a sleeve or socket 3 and a skirt 2.
  • the half-shells are made of a thermoplastic material such as polystyrene Super.
  • Each half-shell comprises at its upper end a semi-cylindrical half-socket 4 connected to the skirt portion 2 by symmetrical planar stiffening webs 5.
  • each half-shell Arranged on the inner walls of each half-shell are a male and female attaching means 9 and 8 respectively, the attaching means of each half-shell being complementary to the mating attaching means of the other half-shell, said attaching means being adapted to be clamped or hooked to each other when subjected to pressure, due to the elasticity of the material.
  • This is achieved by the provision on each attaching means, or member, of at least one oblique surface 27 allowing for easy penetration into the complementary member, while a locking surface 28 allows the two complementary members to be locked to each other.
  • centering means 7a and 7b are provided, the centering member 7a having a hole and being complementary to the centering means 7b which comprise a mating punch-like portion.
  • the inner wall of each half-shell is also provided with a transverse rib 12 extending over the entire width or over part of the width of the half-shell and serving as an abutment adapted to be contacted by the end of the fibre bundle.
  • attaching and centering members may be provided. Instead of being of the pin point type shown in FIG. 2 they may be of the linear type shown in FIG. 5.
  • the attaching and centering members are constituted by transverse plates 37a, 37b projecting from the inner wall of the half-shell and having their free ends 38a, 38b formed into locking hooks extending in opposite directions as shown in FIG. 6.
  • the centering members are constituted by plates 39a, 39b adapted to be applied upon each other as shown in FIG. 6, when the broom is assembled.
  • the webs 5 constitute planar bearing surfaces which prolong or continue the sides 23, 24.
  • One of the webs may be provided with punches 25 while the other web has mating holes so as to provide for greater accurateness of the assembly of the two half-shells.
  • the edges '16, 17 or 18, 19 may be provided with interlocking profiles as shown in FIGS. 5 and 6.
  • the socket 4 adapted to receive the broomstick has a slightly tapering shape.
  • a sleeve or collar 13 provided with a stiffening rib constituting an abutment is mounted on the socket 4; the collar has lateral slots 14, the length of which corresponds to the length of the ribs constituted on the sides of socket 4 by webs 5.
  • the skirt 2 advantageously comprises external ribs 20 and 22 between which a belt 21 is placed for clamping this portion of the assembled half-shells together.
  • the skirt furthermore may be provided with a plurality of conveniently spaced perforations adapted to receive clamping members, assembling staples or similar assembling members with a view to improving the integral connection between the fibre bundle and the skirt.
  • the aforementioned assembling members are masked by the belt 21.
  • the half-shells are also provided with projections arranged adjacent the lower end of the shells and adapted to improve the holding of the fibre bundle; these projections may have any desired convenient shape; they may be constituted, for example, by rows of teeth 10, 11 which are preferably shifted with respect to each other (FIG. 2), or by relatively shifted pointed stubs 40, 42 (cf. FIG. 5) defining between them a planar portion 41, 43; this arrangement allows for easy penetration of the pointed stubs into the fibre bundle.
  • the stubs 42 of the top row have smaller dimensions than those of the stubs 40 forming the lower row; thus, the smaller stubs will more readily penetrate the upper end portion of the assembled fibre bundles.
  • the assembly of the two half-shells may be improved, as shown in FIG. 7, by clamping the lateral portions of the half-skirts together by means of clamps of the buttstrap type the edges 47 of which match corresponding grooves 48 formed on the half-shells. These clamps may be put into place by a simple sliding motion, and they are maintained in their proper position by belt 21.
  • the assembling of the broom is carried out in the following manner:
  • the fibre-bundle is formed by stitching or clamping the bristles together, or by tightly mounting the bristles between two rod members 44 (cf. FIG. 10) the upper end portion 45 being then immerged in a gluing substance maintained in the liquid state by heating and capable of easy solidification, such substance being, for instance, a polyethylene based composition.
  • the fibre bundle is then introduced between the two half-shells with its end abutting the internal ribs or plates 12 (of. FIG. 2) or 37a, 37b, cf. FIG. 5), while the centering members have previously been brought into register.
  • the half-shells are then simply pressed against each other, for example by means of a press, so as to achieve the mutual penetration of the complementary attaching means, as shown in FIGS. 4 and 6.
  • a perfectly integral assembly is achieved either by this pressure, provided the edges 23, 24 and the webs 5 have been previously coated with a convenient adhesive; or by a convenient welding process for connecting the respective portions of plastic material which constitute said edges and webs.
  • the clamps 46 may be mounted by a simple sliding motion.
  • Collar '13 is then mounted on socket 4 and belt 21 is put in place between ribs 20 and 22.
  • the novel broom can be manufactured by a process comprising very simple steps which can be carried out by mechanical means using conventional machinery, while said manufacturing process provides a broom having assembled halfshells which constitute a perfectly integral assembly due to the joint effects of the interior attaching means, the attachment at the periphery of the shells, the clamping effect of the collar and the belt, the novel broom furthermore exhibiting excellent properties of tightness due to the gluing or welding of the half-shells at their mating assembling surfaces.
  • a brush comprising first and second substantially symmetrical half shell portions joined together and defining an embracing skirt portion opening at one end for receiving a bundle of fibers and a socket portion opening at an opposite end for receiving a broom stick, male engagement means on said first shell portion projecting outwardly from the interior thereof, female socket means on said second shell portion engaged with said male projecting portion in a snap-fit, each of said first and second shell portions including a laterally extending stiffening web defined on each side adjacent the juncture of said socket portion and said skirt portion, and a cylindrical collar fitted over said socket portion and having an elongated slot defined on each side thereof through which the stiifening web portions of each of said first and second portions extend.
  • a brush comprising first and second substantially symmetrical half shells defining together an embracing skirt portion opening at one end for receiving a bundle of fibers and a socket portion opening at the opposite end for receiving a broom stick, each shell having inner walls with at least one complementary centering projection and recess which are interengaged for aligning said half shell portions together and at least one complementary attaching means projecting from the corresponding interior surfaces of said first and second shell portions which are interengaged to hold said shell portions together, each of said first and second shell portions having an exterior first rib extending therearound adjacent said one end and a second rib at a spaced location from and parallel to said first rib, and an encircling belt disposed between said first and second ribs and around said skirt portion.
  • a brush comprising first and second substantially symmetrical half shell portions arranged in juxtaposition and defining a lower skirt portion having an opening at one end for receiving a bundle of fibers and an upper cylindrical socket portion having an opening at the opposite end for receiving a handle, each shell portion having a plurality of projections some of which include projecting hook elements and some of which include receiving recesses, a lateral stiffening web defined between said skirt portion and said socket portion on each of said first and second shell portions, one of said first and second shell portions having a projection on said webs and the other having a recess on said webs for receiving the projection for aligning the two parts together, an abutment defined at the inner end of said skirt portion, a bundle of bristles clamped together and disposed in said skirt portion up to said abutment, means projecting inwardly from said skirt portions of said first and second shells engaged in said bundle of bristles, an encircling belt extending around said skirt portion and holding said skirt portion together, and a cylindrical collar fitted over said socket portion and
