Definitions

  • the invention relates to a floor cleaning device with a handle in the form of a handle or a handle and a connected to this, having cleaning elements, carrier, which consists of two with the open side facing and releasably connected, thin-walled plastic shells, of which in the use position upper shell is connected to the handle, while the lower shell has the cleaning elements.
  • Floor cleaning devices of the aforementioned type are used in the form of brooms, scrubbers, hand brushes or as wipers with cleaning elements in the form of a pad.
  • the carriers of such cleaning devices are today predominantly made of plastic, the carriers being solid, receiving the cleaning elements in a firm or detachable connection on their underside and being provided with a handle or handle on their top.
  • the carrier has a handle housing for this purpose, into which the handle is inserted, while the handle is molded directly onto the carrier in the case of hand brushes or the like. Due to the necessarily large use of plastic mass, the material costs are relatively high, which is why one has resorted to inexpensive regenerated plastics, foamable plastics or the like.
  • the invention has for its object to form floor cleaning devices of the above-mentioned construction inexpensive in terms of production and assembly and useful in terms of use.
  • the training according to the invention has the advantage over the generic state of the art that the cleaning device in the case of a self-locking design of the plug connection consists of only two components, in the case of an additional lock of a maximum of three components, which can be easily plugged together and possibly one additional handle can be connected to each other when operating the lock.
  • a similarly simpler one Although connection is known in the hand brush described at the beginning (US Pat. No. 3,008,165), this requires a considerably greater use of plastic material.
  • the invention has the further advantage that lower shells with new cleaning elements or lower shells with other cleaning elements can be attached to the same upper shell, which is not exposed to wear.
  • the lower shell can have bristles, a pad or the like. have and are connected to the upper shell by the simple plug connection.
  • the plug connection provided according to the invention can be realized in a simple manner in that the two shells have mutually adapted undercuts and projections. These can be snap-in or snap connections, in which the elasticity of the shells can be used.
  • At least one projection on the upper shell can be designed as a manually operable locking member.
  • the two shells can be closed by inserting the projections or undercuts into one another and then tilting one or the other shell and connected to one another by actuating the locking member.
  • the locking member can be formed from a rotatable or pivotable handle and a locking lug attached to it or an eccentric. In this way, the locking member with a Bring the simple and short handle into the locked position.
  • the shells preferably have a coordinate symmetry, the lower shell being connectable to the upper shell offset by 90 ° or 180 ° from the basic position.
  • This embodiment is based on the knowledge that, in the case of floor cleaning devices, wear is preferred at certain points on the cleaning elements.
  • these are, for example, the front narrow areas, in the case of a stick broom or scrubber, however, the front slow areas.
  • the stability of the intermediate shell carrier is completely sufficient even in the case of very thin-walled shells with a wall thickness in the range of approximately 2 mm.
  • one of the two shells can be provided with stiffening ribs or stiffening formations.
  • the upper shell advantageously has a style housing that accommodates the handle of the device, which is designed as a stick.
  • the lower shell has two or more further shells or cavities on its lateral boundaries to enlarge the fastening surface for the cleaning elements.
  • the lower shell is preferably formed centrally with respect to the adjacent shells or cavities and congruent with the upper shell forming the stem housing, so that the same Handle housing a lower shell with side shells or cavities enlarging the mounting surface can be attached. In this way, for example, a large-area street broom or the like can be made from a room broom, which is generally relatively narrow.
  • the cleaning elements are attached to the bottom shell of the lower shell by thermal melting.
  • the connection can be made by welding. If this requirement is not met, the cleaning elements can be pressed into the soft plastic floor until they are firmly anchored after the plastic has solidified.
  • cleaning elements in the form of bristles, fibers or also of fabrics, fleeces, tangled fibers or tangled wires can be fastened, the latter possibly being designed to be pillow-shaped.
  • anchoring by thermal melting can be accomplished with any open surface structure of the cleaning elements.
  • the bottom shell of the bottom shell on the outside at the attachment point of the bristle bundles can have strip-like or hump-like thickenings on which the bristle bundles are placed by one of the aforementioned thermal methods.
  • the floor cleaning device shown in Figures 1 to 3 which can be designed for example in the form of a broom, scrubber or a wiper, has a handle 1 and a carrier 2, which is formed from a lower shell 3 and an upper shell 4.
  • a carrier 2 which is formed from a lower shell 3 and an upper shell 4.
  • cleaning elements (not shown) in the form of bristles, fibers, cushions or the like are fastened, while the bottom 6 of the upper shell 4 forms the back of the carrier 2 and at the same time is shaped into a handle housing 7, which Stem 1 takes up via a mechanical connection.
  • the shells 3 and 4 are connected to one another via a plug connection.
  • the shell 3 has 8 projections 9, 10 on its opposite, still reaching shell edges, which are optionally formed like strips.
  • the upper shell 4 has on its downwardly extending shell edges 11 a groove adapted to the strip-like projection 9, so that the upper shell 4 comes into engagement with the lower shell 3 in an angular position.
  • a manually operated lock 13 is provided, which is formed from a handle 14 and a locking lug 15.
  • the handle 14 is designed as a twist grip. In the corresponding position of the carrier 14, the locking lug 15 engages under the projection 10 on the lower shell 3.
  • the lower shell 3 and the upper shell 4 are congruent.
  • 3 further shell-shaped depressions 16 are arranged on both narrow sides of the lower shell. As shown in FIG. 11, for example, these can also be closed to form cavities 17.
  • 3 is made by injection molding, the gem. 11 can be produced, for example, by the blowing process.
  • FIG. 4 which only shows the lower shell 3
  • further shell-shaped strips 18 are arranged on the long sides to further enlarge the fastening area.
  • FIG. 5 shows a longitudinal section through a hand broom, the support 2 of which in turn consists of an upper shell 4 forming the back of the hand broom and a lower shell 3.
  • the two shells 3, 4 are in turn connected via a tongue and groove plug connection 9, 12 in the mutually facing side shell edges 11, 8 and via a lock 13, which can be designed in the same way as in the embodiment according to FIG. 1 to 3.
  • the handle 1 is formed in one piece with the shell 4 forming the back.
  • bristles or fibers 19 are attached to the underside 5 of the lower shell 3 in bundle or package form. If the lower shell 5 and the bristles or fibers 19 consist of corresponding plastics, they can be welded together.
  • the bristles or fibers 19 can be connected to one another by melting their ends on the carrier side and by at least partially melting the underside 5 of the lower shell 3 and pressing them together, so that solidification is provided after solidification .
  • the latter can also be achieved with cleaning elements 20 which are not designed in the form of bristles but, for example, in the form of sponges, pads or the like.
  • FIG. 6 shows an exemplary embodiment in which the lower shell 3, at a distance from its lateral shell edges 8, which are overlapped on the outside by the shell edges 11 of the upper shell, has upwardly extending webs 8a with noses 9a formed at their ends, which in FIG Engage cutouts 12a on the upper shell 4 and latch with their nose-like projections 9a.
  • the cleaning elements 20 consist of individual bristle bundles 19a
  • bump-like or strip-like thickenings 5a are provided on the outside 5 of the bottom of the lower shell 3, onto which the bristles 19a are placed with their carrier-side ends, e.g. welded or inserted by thermal melting.
  • the lower shell 3 is provided with stiffening ribs 3a, while in the embodiment according to FIG. Fig. 9, the lower shell 3 is strengthened by formations 3b and 3c strength.
  • the side shell edges 8 are pulled down and provided on the outside with nose-like or strip-like projections 9, into which corresponding recesses of the upper shell, not shown, engage.
  • FIG. 10 shows an embodiment of the carrier 2, in which the upper shell 4 and the lower shell 3 are connected to one another via a self-locking plug-in connection, in that the lower shell 3 has double-walled shell edges 21, between which the shell edge 22 of the upper shell 4 clamps and is self-locking intervenes. Possibly. the connection can still be improved by internal catches, surface roughness or the like.
  • FIG. 12 shows another embodiment of a manually operated lock, whereby otherwise similar connector elements can be provided, which are not shown in more detail here.
  • the lock 13 has an eccentric mounted on the upper shell at 23, which is formed on a rocker arm 24 which forms the handle and, in the closed position, engages behind the edge of the one shell edge 26 which is drawn inwards to form a projection 25.
  • the lower shell 3 and the upper shell 4 are nested in a box shape.
  • the shell edges 27 of the lower shell 3 overlap the shell edges 28 of the upper shell and are provided with manually operated locking members 13 at their upper region. These have small handles 29 which are each integrally connected to the shell edges 27 of the lower shell 3 via a film hinge 30.
