Definitions
- the invention relates to a suction head on a vacuum cleaner, which suction head is towards the floor to be cleaned open, transverse to the direction of movement of the suction head channel - shaped suction mouth with suction opening and in Direction of movement in front of and behind the suction mouth Bristle strip, which is connected to a carrier plate is.
- a suction head of the construction described is e.g. known from DE-A 27 53 798.
- the bristle strips support when the vacuum cleaner is working cleaning work as dust-removing brushes. They have during the back and forth working movement of the suction head, but also from forces that move the suction head towards the Press cleaning floor and that of an operator are exercised, not insignificant stress to record.
- the bristle strips can also be used as Support elements are used with which the suction head on the cleaning floor is supported. Can be used as support elements but also rollers, sliding elements and similar components, in addition be arranged to the bristle strips.
- the Bristle strips are on the underside of the suction head housing arranged immovably or lifting and using additional components lowerable. In the embodiment with lifting and lowering Bristle strips, the bristle strips are retracted when they hinder the cleaning work, e.g. on deep-pile Carpets may be the case.
- the bristle strips often have one in practice U-shaped sheet metal strip as bristle strip back, into which the bristles are inserted and in which they are clamped are. This is complex in terms of production.
- the bristles are placed on a metal strip, which is, for example, 15 mm wide, with a Length well twice the height of the bristles in the finished Corresponds to bristle strip, transverse to the band direction in defined, uniform layer thickness.
- a steel wire is placed in the middle of the steel strip.
- the Sheet metal tape with the bristles placed on it is U-shaped around the Steel wire bent over with the bristles underneath and compressed.
- the steel wire as a soul prevents that Fall out of the U-shaped bent and clamped by the metal strip Bristles. Then the protruding ones Bristles sheared to finished height. If necessary Cutouts are punched in and the bristle strip is opened Production lengths cut to length.
- the described embodiment one keeps for reasons of strength and reasons of Dimensional stability required for when working with the vacuum cleaner to absorb significant stress are.
- the invention is based on the technical problem, one Suction head of the construction described at the beginning with bristle strips equip that simple and shapely in one industrial mass production can be produced can be easily assembled and all loads to be absorbed easy and with a long service life and shape stability record, tape.
- the invention is based on the knowledge that the Bristle strips of a suction head of the bristle strip back as a stiffening backbone on a support plate can serve and can fully fulfill this function if the Carrier plate is designed as indicated and the bristle strip back cohesively connected to the carrier plate are, such that the bristle backs the Support plate against deformations caused by stress the plate level and the backing plate the bristle back against stress-related deformations in Stiffen the direction of movement of the suction head. So far the invention works with a special design and Union of the bristle bar back and the carrier plate, which is also easy to assemble and in which the Bristle strip back on the one hand and the carrier plate on the other hand interact favorably.
- the bristle backs train in the case of deformations caused by stress out of the plate level, stiffening as it were, as in the construction industry with the so-called shell statics are used, while on the other hand the area moment of inertia the support plate stiffening on the bristle strips acts in the direction of movement of the suction head Have to absorb stresses.
- the special cleaning can be set up at the same time the bristles in the back of the bristle strip become safe and with held for a long time.
- the carrier plate Moldings and other shapes are not required, which enables production by extrusion.
- Bristle back and the backing plates from the same thermoplastic.
- the back of the bristle strip can be formed into shaped edge grooves the carrier plate and with the material of the edge grooves be cohesively connected. But you can also do that Shape the bristle strip back onto the carrier plate and at the same time the bristles in the back of the bristle strip fasten by injection. With the measures described can by injection molding, but also of Extrusion.
- the carrier plates with The molded bristle strips can be elongated Products are made by extrusion. When extruding can also the bristles in the thermoplastic Material of the support plate are introduced.
- Back of the bristle strip and the carrier plate are angularly rigid with one another connected, which also in the area of angles Formations increasing the moment of inertia are provided could be.
- the suction head 1 shown in Fig. 1 belongs to a Vacuum cleaner.
- the suction head 1 has one to be cleaned Open floor, transverse to the direction of movement of the suction head 1 extending channel-shaped suction mouth 2 with a not shown suction opening and in the direction of movement in front of and behind the suction mouth 2 bristle strips 3, which with a support plate 4 are connected.
- the Bristles 5 of the bristle strips 3 in one made of thermoplastic Plastic molded bristle back 6 embedded are.
- the bristles 5 are preferably also made made of a thermoplastic. If you take the Fig. 4 and 5 add, it is clear that the bristle back 6 as stiffening edge elements for those made of thermoplastic Plastic molded carrier plate 4 is formed are.
- the height h of the bristle strips 3 in the direction of Bristles 5 is large in relation to the thickness d of the carrier plate 4. Nonetheless, the component is carrier plate 4 with bristle strips 3 in the suction head 1 according to the invention sufficiently stiff.
- the bristle back 6 and the carrier plates 4 are integrally connected. Further is the design is made so that the bristle back 6 the support plate 4 against stress-related deformations out of the plate level and the carrier plate 4 die Bristle strip back 6 against stress-related deformations Stiffen in the direction of movement of the suction head 1.
- the Bristle strip back 6 in molded-on edge grooves 7 of Carrier plate 4 used and with the material of the edge grooves 7 cohesively connected.
- they are Bristles in a strand of thermoplastic material, which forms the bristle back, embedded; on the other hand, the bristle strip back is in the marginal grooves glued or welded to the material of the edge grooves.
- the bristle strip back is in the marginal grooves glued or welded to the material of the edge grooves.
- the bristles 5 in the marginal webs of the one-piece Carrier plate embedded. The webs form stiffening edge elements and at the same time the bristle bar back 6.
- the 4 and 5 object is shown by Extrusion and thus producible in one operation.
- Bristle strip back 6 can be made of melted bristle material consist; but it can also be made of material, e.g. B. Recycled, which are added during the extrusion becomes.
- the carrier plate 4 with the molded bristle strips form a one-piece component. The manufacturing and assembly effort is compared to the state of the Technology significantly reduced.
- the bristle backs 6 and the carrier plate 4 are angularly rigid with one another are connected when they are shaped as shown. It is understood that the thermoplastic plastic a appropriate hardness.
- the bristle back 6 and the carrier plate 4 suitably consist of same thermoplastic.
