Description

MECHUDE Description Technical d The invention relates to a bundle for attaching to a broom handle comprising a strapping to which substantially transverse strips relative to the shaft axis are attached, a quantity of relatively loose absorbent strips of a textile material. STATE OF THE ART A hook of the type under consideration is known from the German utility model 76 25 260. The absorbent strips attached to the bung transversely to the longitudinal direction of the broom handle are usually made of a cotton felt. In particular in the wet state they do not have any elasticity and hang freely swinging downwards in a similar way to skeins. By virtue of the little body of the cotton felt that forms them, it results in a sparse appearance. During the oscillating movement that occurs when carrying out the cleaning of floor surfaces there is also the latent danger of a mutual contact between the synthetic material binding and the furniture and walls, which can lead to damage on both sides and is unsatisfying. Embodiment of the invention The object of the invention is to improve a product of the type under consideration so that at the time of avoiding a significant increase in production costs an appearance of more body is obtained even in the wet state, as well as a decrease in the danger of damage to the strapping and / or furniture in the case of contacts due to involuntary shock. According to the invention, this task is solved with the distinctive features of claim 1. The subordinate claims refer to favorable embodiments. In the hook according to the invention, at least one elastic body is provided which causes the strips to expand at least in the area of the strapping. By this the hair gets even in the wet state of the strips a larger body appearance, which makes it look more pleasing. The elastic body also prevents the strips from hanging down and oscillating parallel to the shaft axis. By this they protrude from the strapping in the lateral direction even in the wet state, which leads to the fact that in the case of a side impact contact against a solid surface, the strips are crowded between the surface and the strapping. This results in a cushioning of the shock and prevents bilateral damage in the event of contact with inflexible objects. The elastic body can be in the form of a foam body of polymeric material, for example of polyurethane foam, which supports the strips that are softly clamped at least in a partial area. Conveniently, the elastic body is fixed directly or indirectly to the strapping, and is arranged so that a support is obtained on the inner side of at least a part of the straps. It was found to be particularly convenient if the elastic body has such dimensions that it overlaps the strapping in the lateral direction. Although this can not easily be seen from the outside, an elastic body configured in this way exerts an elastic support effect on the strips, which greatly helps to prevent damage when the object touches an inflexible object during lateral oscillatory movement . In the embodiment of the hoist in which the strapping and the strips of the theoretical extension of the pole are arranged substantially in a symmetrical distribution it was found convenient that the elastic body is symmetrically configured in a manner substantially corresponding to that of the distribution. Accordingly, in the case of embodiments in which the strapping has a circular shape, the elastic body should also be configured in a circular manner. However, it is perfectly conceivable to give the zunchado the outline of a regular polygon. The elastic body would then have to be configured correspondingly and associated with the strapping so that a relative torsion is prevented. There is also the possibility of using an elastic body in the form of an elastic band, which at least in a partial area is laminated on at least one side of the strips. In this, it is not absolutely necessary to cover all the strips with a corresponding elastic band. Rather it may be sufficient for the individual case to configure correspondingly only the straps of the piece resting on the upper part. In general, such strips are provided with a centrally disposed opening, they are threaded on a pin of the strapping and distributed evenly in the direction of the circumference. The strips that rest on the upper part are therefore unequivocally defined. In order to avoid a deterioration of the cleaning effect, it turned out to be advantageous if the tape is only provided in the area of the stick and overlaps the strapping in the lateral direction. By this, the components of the determining strips for the achievement of a good cleaning effect, and especially their protruding ends, can continue to penetrate into fine surface inequalities, which is important for a good cleaning effect. The tape in general may consist of a sheet and / or a rubber band. However, it was found to be convenient that it consists mostly of synthetic fibers that are superficially bound. Due to the respiratory activity that results in the case of such an embodiment, the drying process after the previous wetting is favored, thus preventing putrefaction and improving the duration of the useful life of the mop. The tape has particularly good unchangeability if the synthetic fibers forming it are joined to one another by mutual fusion at separate location points. In this, an especially pleasing appearance is achieved if the fibers, at least in part, consist of divided split fibers. Apart from the velvety appearance of the surface, this embodiment results in good elasticity as well as good spring elasticity coupled with good wear resistance. However, comparatively low surface weights are sufficient to achieve the desired increase in the elasticity of the strips.

The tape can be joined to the strips by mutual sewing. Against this it was found to be convenient both from the technical aspect of production as well as from the hygienic point of view if the tape is joined with the strips by a meltable glue in places of separate location. As meltable glue, for example, polyethylene powder can be used, the adhesive particles of which after being applied have a separation smaller than approximately 2 mm between them. BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained below on the basis of the drawings. 1 shows an exemplary embodiment of the hook in perspective view from above, FIG. 2 shows the hooking area of a hook according to FIG. 1 in cross-sectional representation, FIG. 3 shows an exemplary strip to be used in FIG. a hook of the type shown in FIGS. 1 and 2. Embodiment of the invention The hook shown in FIGS. 1 and 2 is used in particular for wet floor cleaning. It is intended to be fixed to a broom mast 1 and comprises a strapping 2 to which a strip 3 absorbing a textile material is fixed substantially transversely to the axis 6 of the mast 1. In the case of the textile material, it can be a cotton felt with a surface weight of 100 to 300 g / m 2, preferably with a surface weight of 180 to 220 g / m 2, which can optionally be provided in the area of its upper side with an improved pattern in terms of wear resistance. The print may consist, for example, of a foamed latex and contain components of a brand and / or graphic symbols. Conveniently the stamping should have a configuration such that it does not cause a noticeable stiffening of the cotton material. The strips 3 shown in figure 3 in plan view are laminated in the central area on the upper side with a felt fabric of divided split fibers, with a surface weight of 40 to 100 g / m2, suitably with a surface weight of 60 to 80 g / m2. Split fibers of this type are produced in the form of strands of fibers. During the carding process they are superficially joined and then subjected to spot welding in which the fibers forming the felt melt so that they transition from one to the other in separate location sites. After this the product obtained is treated with very fine jets of water directed at high pressure against the surface, which has the consequence that the microfibres that form the split fibers are released one from the other between the glue points, which It gives the product a spongy appearance and a structure like a fabric. However, there is good elasticity. From the product obtained in this way, the ribbons are then separated and, as shown in FIG. 3, they are bonded with the cotton strip 3. For this purpose, a meltable glue in the form of powder is introduced into the intermediate zone between the strip 3 and the strip 5 and the lamination obtained is subjected to the effect of pressure and heat, for example by ironing until a softening and a glueing is obtained. mutual of both layers. During the cooling that takes place next this glue obtains a high degree of resistance. However, it has a textile-like softness and a good elastic spring because the adhesive zones are separated from one another and do not significantly reduce the water permeability of the laminate. The strips are inserted into the strapping in the manner shown in Figures 1 and 2 and anchored therein by a mushroom head 7. This consists of synthetic material and on the underside is joined with an elastic body 4 of a polyurethane foam, which like the strapping 2 has symmetrical rotation configuration but nevertheless has a diameter D that overlaps in the lateral direction the diameter d of the strapping. By colliding laterally with inflexible objects, this results in shock damping. By this, damage to the strapping 2 is largely prevented. Additionally, it can be seen in FIG. 2 that a corresponding effect of the straps 5 overlapping the strapping 2 in the lateral direction and sticking with the straps 3 in the area is also obtained. of the stick 1. If necessary they can completely replace the body 4 elastic, complement the elastic body 4 or be replaced by the elastic body 4.
