Definitions

  • the invention relates to a synthetic broom or brush, in particular a grass brush, comprising a handle and a bristle portion with fibers or bristles of a synthetic material, which are held in the turns of at least two strands twisted together, in particular a twisted wire.
  • the traditional Indian grass broom is the preferred cleaning agent in India. It consists of a handle of about half a meter in length and an approximately as long frond with fibers of grass. Depending on the quality, about 300 g of grass are used for the frond. To sweep, the user takes the broom in one hand, bends so far forward that about 30% of the broom touches the floor and guides the broom in this pose to remove the dirt from the floor.
  • a disadvantage of the traditional Indian grass broom is its low durability.
  • the floors in Indian households are usually very hard.
  • the durability of a grass broom is only between about three to six months.
  • Another disadvantage is that it loses particles and later also entire grass tufts during the entire lifetime.
  • the necessary acreage for the grass for making the broom are limited.
  • the grass fronds are preferably made of grass, which is grown specifically for this purpose in the northeastern regions of India.
  • a broom of the generic type consists of a handle and a bristle portion of synthetic fibers, wherein the fibers are held in the manner of a bottle brush by twisted wires together.
  • Grass broom as close as possible to a traditional grass broom in terms of its fiber volume and volume, usually several twisted wires are combined with fibers to form a bristle part.
  • the twisted wires extend in the interior of the bristle part over a length of about two-thirds of the bristle part.
  • the known synthetic grass brush is characterized by a high durability and also loses no particles, but has the disadvantage that its service properties are significantly worsened by the twisted wires.
  • the traditional grass broom is very soft and clings to the soil to be cleaned, the well-known synthetic Broom relatively stiff. In particular, when the wires touch the ground during bending, the rigidity of the bristle portion increases abruptly.
  • the object of the invention is therefore to develop a synthetic broom of the type mentioned so that it is simple and inexpensive to produce and also when using synthetic fibers
  • a grass brush comprising a handle and a bristle portion with fibers or bristles of a synthetic material, which are held in the turns of at least two strands twisted together, in particular a twisted wire, which twisted together
  • a synthetic grass brush according to the invention thus largely corresponds in its use properties to a traditional grass brush.
  • the strands which are twisted together to integrate the fibers or bristles, can be made of any materials, eg. B. plastic. A prerequisite for their suitability is merely that they essentially retain this shape after twisting and shaping the helix.
  • a twisted wire according to the invention may also comprise a plurality of individual wires twisted together.
  • Fiber amount can be tied. Due to the central arrangement of the twisted wire in the interior of the frond, on the outer circumference of the fibers are arranged and protrude from there down, a broom according to the invention also comes in its appearance
  • the bristle part of a grass broom from several helically formed twisted wires with fibers. These For example, they may be arranged "in series" along a core, such as described below, or parallel to one another (eg, double, triple helix)
  • Grass brooms can be varied over the formation of the coil, for example, over the number of turns, their pitch, the diameter of the coil, etc. within wide limits.
  • the helix can be formed differently in different regions of the bristle part.
  • greater flexibility in the lower portion of the bristle portion of the broom is achieved by increasing the number of turns per unit length toward the bottom of the broom.
  • the same effect can be achieved in that the coil tapers conically towards the lower end of the bristle part of the broom.
  • the fiber density can also be increased in a simple manner.
  • the synthetic grass brush according to the invention corresponds in its
  • the length of the helix depends on the desired length of the bristle part and is preferably between 30 and 70 cm.
  • the diameter of the helix is chosen so that the outer diameter of the bristle part corresponds to that of a natural grass broom and is preferably between 50 mm and 150 mm.
  • tubular core preferably made of a plastic material, particularly preferably of PP (polypropylene), HDPE (High Density Polyethylene), EVA (ethylene vinyl acetate) or a mixture of these materials assigned.
  • PP polypropylene
  • HDPE High Density Polyethylene
  • EVA ethylene vinyl acetate
  • the twisted wire with the fibers is preferably wound on the flexible core.
  • the positioning of the twisted wire with the fibers on the core can be facilitated by providing on the outer circumference of the core a groove or positioning ribs for receiving the twisted wire with the fibers.
  • the core can be additionally profiled. This has the advantage that the tool for producing the core can be made simpler.
  • the flexible core can conically taper downwards.
  • Typical dimensions for such a core are: length: 20 cm - 70 cm, preferably 55 cm; Diameter: 2 mm - 35 mm, preferably 6 mm - 25 mm.
  • the diameter of the individual wires is advantageously chosen so large that a sufficient clamping force for the fibers is achieved. Also, depending on the length and the material of the individual wires to make sure that the diameter is large enough that they do not break during twisting. When using two individual wires for a twisted wire, diameters in the range of 0.8 to 4.0 mm, preferably between 1, 0 mm and 1, 5 mm, have proven to be advantageous.
  • Galvanized steel is preferably used as the wire material, since this material can be bent well. In addition, it has a high tensile strength, whereby a high clamping force can be achieved when twisting the wires without the wire tearing.
  • the fiber material used is preferably polypropylene.
  • Polypropylene fibers have the required durability and are also very cost effective.
  • Other plastics such as PET (polyethylene terephthalate), PS (polystyrene), PVC (polyvinyl chloride) can also be used.
  • fibers of different materials for example the above, can be combined with each other. Both fiber mixture can be used, as well as in different
  • the length of the fibers is preferably between 150 and 700 mm
  • Shorter fibers have the disadvantage that, when swept, few fibers are in contact with the ground, or the flexible core may easily come into contact with the ground. For longer fibers, the problem arises that the bristles deform too much, or the required pressure during sweeping can not be applied. Alternatively, with long bristles, the bristle diameter would have to be increased, which would increase the total weight of the brush.
  • the fiber diameter is preferably between 0.2 and 1.5 mm, more preferably about 0.3 mm to 0.7 mm.
  • Thinner fibers have the disadvantage that they deform too easily at the preferred length or become too flexible, whereby the cleaning performance decreases. For thicker fibers, the stiffness increases and the fibers do not conform so well to the floor (poor cleaning performance). In addition, the number of bristles usually decreases at the same application weight. It is also possible to provide fibers with different diameters, for example in the form of a mixture. But there can also be fibers with
  • the profile of the bristles used may be round, oval, star-shaped, rectangular, diamond-shaped or tri-pointed (trilobate).
  • the dreispitzförmige design has the advantage that the flexural rigidity of such a bristle is similar to a round bristle, but by the three-pointed design, the material usage can be reduced.
  • the fiber ends are preferably split. They can be cut open with knives, for example.
  • the fiber ends are mechanically processed, whereby the fiber ends, if the fibers consist of several mutually immiscible materials, tracked.
  • the fiber weight is preferably between 100 and 400 g. At low fiber weights arise on the one hand, a poor quality impression and on the other a poor cleaning performance. At higher fiber weights, the broom becomes too heavy and therefore unwieldy or too expensive.
  • the handle can be made of PP (polypropylene), HDPE (high density polyethylene), PS (polystyrene) or ABS (acrylonitrile-butadiene-styrene). Of course, recycled materials or materials from renewable raw materials can also be used. HDPE is preferred since this material is favorable and can be processed in the economical blow molding process.
