TOOL, IN PARTICULAR A CLEANING TOOL AND
APPLICATION THAT INCLUDES A VASTAGO AND A GRIP ELEMENT
DESCRIPTION OF THE INVENTION The invention relates to a tool, especially a cleaning and application tool according to the main idea of claim 1. As a tool, home tools, such as brooms, brushes, mops, are known in the first line of the invention. , wetting devices for the floor and the windows, but also rollers for painting and apparatus -special for painting, pressure rollers for rugs etc. that not only have a handle but also have a long rod with which a part of the work is carried out and, if necessary, it is also pressed. Such handle apparatuses are currently formed of a smooth-walled metal roller or an extruded plastic tube. Due to the saving of material, a small diameter is made, which is currently 18 to 24 mm. The small diameter and the smooth wall make it difficult to manually apply the guide and pressure liquids on the rod and the working part itself. The guidance and the exercise of pressure of the work part have an important role in such tools, whose part of work is not united

rigidly with the handle but by means of a joint. This is especially true for a multiplicity of wet cleaning tools. Furthermore, rods are known, which offer the possibility of an extension, when either auxiliary parts are fitted together or the rod is constructed telescopically. The grip of the rod is more important the longer it is. Up to now they have been limited to providing a handle-shaped conformation on the free end of the rod, but with this only the guiding forces can be transmitted better, but not the pressure force that could be applied with the other hand to some distance from the rod. In the telescopic parts it is known (DE 296
23 812 IU), in which the tubular part forming the rod is provided with a polygonal section, especially a rounded triangular section and in the region of the tube passage from a diameter greater than a smaller diameter, place a plastic sleeve, which present a corresponding polygonal cross section and also present in the means for fixing the extension of the rod. With that polygonal cross section in the tube as well as the plastic sleeve that forms the handle, it should be
possible better handling and with this ergonomic work. Simultaneously if the working part is rigidly or articulatedly connected to the external rod part, the triangular shaped cross section will not offer any optimal ergonomic solution and neither will attention be paid to the different sizes and lengths of the user's arm. From DE 296 03 936 Ul, from which the main idea of claim 1 departs, such a tool is known which shows a handle with a gripping handle, which can be placed on a rod in the axial position that is want and also in the desirable radial position, this is in a rotational position. For this purpose, a grip lever is pivotably mounted on the grip sleeve, which is pivotable between a grip position, in which a radial grip force and a release position are applied to the rod, in which the grip sleeve and with this the handle can be moved and adjusted with respect to the rod. Although in this way it is possible to achieve - an individual adjustment of the position of the handle to the body magnitudes of the user, this with the DE 296 03 936 Ul joined the disadvantage that the grip lever in its grip position, that is to the place the device of
The work protrudes in the form of a hook from the grip sleeve, which presents the danger, the user remains hung on the lever or until it is damaged. The invention proposes the task of creating a tool of the mentioned type, in which the danger that the user engages with the gripping element is minimal. This task is solved with a tool of the aforementioned type, in which the gripping part in its gripping position extends substantially continuously with its external surface to the external surface of the sleeve. In this way, the grip piece is prevented from protruding from the sleeve in its grip position and by means of a direct transition between the outer surface of the grip part and the external surface of the sleeve, it is excluded that the user engages in it. Also in the tool according to the invention, it leads the loose grip element on the rod and can be provided as a loose constructive part and will be able in both cases to be adjusted by the user to his debit habits, his work, his body size and / o 'arm length in an optimal ergonomic manner, where such a grip element serves
in the first place for the application of pressure forces, so it is applied at a distance from the end of the rod. This is especially advantageous in conjunction with measuring rods, especially in relation to rods of different length, for example snap rods, telescopic rods, or rods combined with fitting parts and telescopic parts. With these elongated rods, not only an adjustment to the user's body size is possible, but especially a variation of the reach length. In both cases, the inward or rotary adjustment of the handle or handle is possible to an ergonomically favorable position for the user. The gripping element surrounds the rod in the form of a sleeve. Such a sleeve can be constructed essentially closed and fixed with a gripping means acting with a force closing between the sleeve and the rod, where in the first line a friction closure comes into consideration and the fixation is releasable, in order to be able to case given adjust the grip or handle element. The gripping means has a gripping part mounted on the sleeve acting in a force closure with the rod, and is manually operable. The gripping part can have a shape in the form of a penetrating hinge or else
an elongated lever shape, which in its grip position is approximately parallel to the rod. Here, however, it must be ensured for every embodiment that in its gripping position the gripping piece with its smooth outer surface with respect to the outer surface of the sleeve remains. In a preferred embodiment of the invention, the sleeve is provided with a socket formed between two spaced faces and the grip part in its gripping position at least partially in the socket. The faces thus formed in the sleeve run essentially parallel to each other. In particular, the gripping part can be pivotably mounted adjacent to the faces and at least partially penetrate between the faces when tilting to its gripping position. In a special embodiment of the invention, it can be provided that the gripping part is in its gripping position completely inside the socket, that is, between the faces, where preferably the outer side of the gripping piece is at the level of the edges. free from the faces, so that here too an excessive backward cutting is avoided, which would entail the danger of snagging. Especially if the piece of grip on your
The grip position does not fully penetrate the socket, it can be provided in another embodiment of the invention, that the gripping piece in its internal area opposite the rod has a recess on opposite lateral surfaces and that the faces that limit the grip in the position of the gripping part each time they are arranged in a corresponding recess. The recesses that are formed as inwardly pulled areas encounter the walls in the adjustment of the grip piece supported by the inner side and thereby serve to guide the grip piece during adjustment. In the grip position, the recesses completely fill the recesses, where it is especially provided, that the depth of the recesses essentially corresponds to the thickness of the walls that limit the socket, so that the walls with their upper surface on the outer side be smooth with respect to the surface of the neighboring gripping part of the recesses, and do not protrude beyond the recesses. The gripping part is • rounded or smoothed on the outside to prevent edges and cuts backwards. In particular, it can be provided that the gripping part on its external side radially has a convexly rounded contour,
this is on the opposite side to the rod, where the convexity may be formed in the longitudinal direction of the rod and / or in the peripheral direction of the rod. In a possible embodiment of the invention, it is provided, that the gripping piece acted directly on the rod and tightened with it to the sleeve. However, alternatively, it can also be provided that the sleeve has a gripping plate arranged between the gripping part and the rod, and that the grip piece presses in its gripping position the gripping plate against the external surface of the rod, that is to say that act indirectly on the rod. The arrangement of a gripping plate has the advantage that the gripping force can be applied over a larger surface, so that after a long use of the tool, a still secure hold of the gripping element on the rod is also guaranteed. . Preferably, the gripping element is modeled or ergonomically profiled on its external side, thus, depending on the retention and guidance of the tool, it conforms to the user's hand shape. Due to the external diameter, however, a longitudinal and, in some cases, transversal profiling is achieved in the simplest case.
In addition, the gripping element can have at least in partial regions a friction-increasing layer, which, for example, consists of an elastic rubber material. It can be a complete coating or a strip or something similar. But, especially, the sleeve and the friction-increasing layer can be manufactured in a two-component injection process. It is also possible for the gripping element itself to be totally or partially consisting of an elastic rubber material, for example an elastomer, whereby not only the grip is increased, but also the grip on the rod, when parts of the gripping element directly exert the effect of grip. Other features and qualities of the invention are apparent from the following description of exemplary embodiments with reference to the accompanying drawings. Where Figure 1 shows a view of a rod with the gripping element placed in a gripping position; Figure 2 shows the rod according to figure 1 with the gripping element in the open or release position; Figure 3 shows an enlarged cut in the area of the upper end of the gripping element in the position
of grip; Figure 4 a section corresponding to fig. 3 in the release position; Figure 5 is a view of an interrupted rod interrupted with a second embodiment of the gripping element in the gripping position; Figure 6 shows the embodiment according to Fig. 5 in the free position and in section; FIG. 7 shows an enlarged section of the gripping element according to FIG. 6 in the released or free position; and Figure 8 a representation corresponding to Fig. 7 with the gripping element in the gripping position. Figures 1 and 2 show a dotted image of a rod 1, which has a cylindrical circular cross section along its entire length and has at its free end a rod hood 2 with the hanging ear 3 and at its opposite end a threaded part 4 for the placement of a working part. In the working part it can be, for example, a broom, brush or something similar. The gripping element 5 is seated on the rod 1, which adjusts in its contour
ergonomic at the hand of a user, and to this end presents a carved configuration. The gripping element 5 forms a sleeve 6 (Figs 3 and 4) which is closed and which includes the rod 1 and is provided at its end opposite the free upper end of the rod with a recess or reception socket 7, which is limited by two. faces 6a a certain distance, which essentially run parallel to the longitudinal direction of the rod 1. On the faces 6a, a gripping part 8 is mounted on a hinge 9, which forms a pivot axis running substantially perpendicular to the longitudinal axis of the rod 1. The gripping part 8 has a penetrating nut shape and in its outer contour 8a a rounded shape convexly outwardly. Figures 1 to 4 show that the convexity occurs in the longitudinal direction of the rod 1. Additionally, the grip piece 8 also has a convex rounded external contour in the peripheral direction of the rod 1, that is essentially perpendicular to the FIG. 1 to 4 is a plan view. On its surface in front of the rod 1, the gripping part 8 has a trough-shaped concave depression 10, which is partially constructed as a cylinder and, for example, fits the
contour of the rod 1. As shown in Figure 2, the gripping part 8 also has in its internal area opposite the rod 1, on opposite lateral surfaces each time a notch 8b, whose depth corresponds essentially to the wall thickness of the faces 6a. In addition, the gripping part 8 has a cam 11, which cooperates with the surface of the rod 1. FIGS. 2 and 4 show the gripping part in the open or loose position, while FIGS. 1 and 3 show the grip piece 8 in the grip position. In the grip position the cams 11, which is disposed in a radial plane below the joint 9, a counter-support, by means of which a radial force directed inwards on the rod 1 is applied from the gripping part 8, whereby the gripping element 5 fixed in its position of adjustment on the rod. As shown in Fig. 1, the faces 6a in the gripping position of the gripping part 8 fill the recesses 8b of the gripping part 8 completely, where between the external surface of each face 6a and the external surface 8a of the part of grip 8 a smooth and continuous surface is formed without step. Also the convex external contour 8a of the gripping part 8 is
it joins continuously in the tightening position of the gripping part 8 continuously in the following contour of the gripping part 5 or of the sleeve 6. In order to put the gripping part 8 in the free position, the user tilts the part of grip 8 around the articulation 9 to the position shown in Figures 2 and 4, in which the cam 11 is out of engagement with the rod 1. In the free position the gripper can both rotate and move axially with respect to to the rod 1, as indicated by the arrow provided in fig 2. The user can thereby fix the gripping element 5 in a position comfortable for the user and there fix it. The exemplary embodiment according to Figures 5 to 8, shows the gripping element 5 with a closed sleeve 6 that encompasses or surrounds the rod 1. Also here the gripping element 5 has a socket 7, on which the grip piece 8 around the articulation 9 pivotably. The gripping part 8 is in this case provided with an elongated gripping lever 12, by means of which it can be set from a free position according to Figs. 6 and 7 by the inclination of the gripping lever 12 with respect to the rod 1, then being brought to the gripping position; then the lever of
grip 12 almost parallel to the rod 1. As shown in Figures 5 and 8 is the gripping part 8 with the gripping lever 12 fully received in the socket formed between the faces 6a and introduced to the level. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects or products to which it refers.
