Description

Territory of invention

The The present invention relates to a handle holder, in particular for stems of cleaning equipment like brooms, mops and the like, and serves to provide the provided with a stick holder cleaning devices on fast and easy way to attach, for example, cleaning cart.

State of technology

Devices of this type are well known. For example, in the US 4,722,113 discloses a device for attaching a mop to a bucket comprising a stalk holder attached to the handle of the mop with an approximately vertically downwardly directed wedge-shaped connecting element and a bucket attached receiving device, the latter having a wedge corresponding recess, in which the stem holder with the wedge is used. The fixation of the handle holder on the stem is carried out by means of a screw to be mounted sleeve whose hollow cylinder-like lateral surface is open at one point for spreading recording.

Similar type sleeve or bush-like stem holder are in the publications DE 1 876 148 U . DE 1 973 197 U or GB 2 388 156 A described, wherein the former relates the holding force exclusively via a clamping screw and the other two exploited only the clamping action of the sleeve without the use of screws for fixation on the stem. From the cited documents are also connection or suspension elements in the form of holes or hooks, also integrally formed on the sleeve or bush-like stem holder, known.

The However, known stick holders have on the one hand the disadvantage that It may well be fixed on the handle when using screws or wedges but only awkward attached or solved can be while In the case of elastic claws, they are relatively simple on the stem attached or detached from it can be however, the fixation due to the necessary elasticity of the claws is relatively weak and the claws can also break over time. are the claws formed from too rigid material to the clamping force increase, this in turn makes it difficult to attach or detach the steep holder. nevertheless is a quick height adjustment of the handle holder in both systems on the handle pretty awkward.

presentation the invention

task the present invention is to develop a stick holder, easy and fast anywhere on a stick attach and detach leaves, without the holding strength of the stem in the attached state to compromise. Here, special attention is paid to the fact that the attachment and detachment can also be made quickly in a row, so that a simple Adjustment along the stem is enabled.

These Task is by a handle holder with the features of the protection claim 1 solved. advantageous versions follow from the subclaims.

Of the Stem holder according to the invention has a handle receiving opening, defines the two partial holes, wherein the minimum diameter of the first partial bore is such that a circular cylindrical stem with a defined outer diameter is slidably movable in the first partial bore in the handle holder, and the minimum diameter of the second partial bore is sized that the stem is essentially fixed in the second partial bore is, and wherein the stem from the first part of the hole in the second Partial bore and vice versa is movable. Through the mobility of the stem in the first partial bore, the stem holder can quickly put on the stalk and by moving in the fixed Position be brought in the second part of the hole. A fast and easy switching between the released and the fixed position allows thus also a quick and easy movement of the handle holder along of the stem.

It It should be understood that the term "bore" is not necessarily a circular bore is meant, and that deviations from the circular shape are possible, as long as the minimum diameter of the bore, i. the minimum dimensions the bore in a radial direction perpendicular to the axis of the bore, have the above properties.

Prefers is the minimum diameter of the second part of the hole in essence equal to the diameter of the stem, leaving the stem in the second Partial hole is determined by press fitting. The minimum diameter the first partial hole is larger than the diameter of the stem, leaving the stem in the first partial bore is slidable.

Prefers the axes of the partial holes are at an angle to each other arranged. Thus, the movement of the stem between the holes by mere Buckling of the stem relative to the stem holder can be effected.

Furthermore, it is preferred that the second partial bore has two clamping surfaces which are axially offset from one another. Thus, a special allows good fixation of the stem in the second bore.

Of the Stem holder preferably has a higher elasticity than that Stalk. This will cause the stem to move between the two sub-holes further eased.

Farther is the clamping surfaces the receiving opening of the handle holder preferably roughened. This will increase the liability between Stem and handle holder in fixed state further increased, without that the slipperiness in the dissolved Condition significantly impaired becomes. Alternatively you can the clamping surfaces the receiving opening of the handle holder preferably with a rubber-elastic coating be provided whose high coefficient of friction excellent adhesion in the specified state.

Finally includes the stem holder according to the invention furthermore prefers a hook with which the handle holder can be suspended, wherein the hook is preferably formed integrally with the handle holder.

Of the Hook may in a preferred embodiment two side by side lying hook arms which have a slot for receiving between them define another stem or a vertical carrier. Thus, can the stem holder according to the invention hold two cleaning instruments or with the slot on a vertical support structure are attached.

Short description the drawings

In the following the invention with reference to embodiments according to the 1 and 2 explained.

1 shows a side longitudinal sectional view of the handle holder according to the invention, in which the handle holder is shown with inserted stem in its released position.

2 shows a side longitudinal sectional view of the handle holder according to the invention, in which the handle holder is shown with inserted stem in its fixed position.

3 shows a perspective view of another embodiment of the handle holder according to the invention, in which the hook has two arms.

Ways to execute the invention

In the following 1 and 2 a preferred embodiment of the handle holder is shown. The stem holder comprises a body 1 in which a receiving opening 2 for receiving the stem 10 is formed, and a hook 5 with which the handle holder can be attached to, for example, a cleaning cart. The receiving opening consists of two partial holes 2A and 2 B whose respective diameters are denoted by D _A and D _B.

In 1 It can be seen that the diameter D _{A is} dimensioned sufficiently larger than the diameter of the stem D _S , for example by 0.5 mm, so that in the partial bore 2A picked stem can slide in this and be moved. On the other hand, the diameter D _B is chosen so that in the partial bore 2 B picked stalk, in 2 is determined by press contact with the walls of the bore. For example, D _B = D _{S can be} +/- 0.1 mm.

Although the press contact in the specified state only by the wall 3 is sufficient to the stem 10 to hold slipping, is provided in the embodiment shown that in addition the offset in the axial direction wall 4 with the stalk 10 is in press contact and thus provides a particularly strong holder.

As can be seen from the figures, the partial holes 2A and 2 B arranged with their longitudinal axes at an angle α. Thus, it is only necessary to bend the stem with little effort in the stem holder to the stem of the partial bore 2A into the partial bore 2 B or snap in the other direction. This allows a quick and easy adjustment of the handle holder along the stem.

In another embodiment, the hook 5 two hook arms arranged side by side 5a . 5b on, which has a gap between them 6 define. In this gap 6 can either be another stalk 7 For example, a dustpan, or the stem holder can thus be attached to a vertical rod, such as a cleaning cart instead of a horizontal rod. The distance between the two arms is accordingly chosen slightly smaller than such a stem or such a rod and can be roughened or provided with a rubber-elastic coating.

The handle holder disclosed in the following claims can be fastened to handles of cleaning appliances such as mops, brooms, window cleaning appliances or similar devices in a simple, quick and convenient manner, the handle being securely and firmly fixed in the secured position Handle holder is encompassed. The handle holder can be on or for this purpose at points provided for example cleaning trolley or in storage rooms. The skilled person will undoubtedly further advantageous embodiments with reference to the can be seen here, which are also within the scope of this invention.
