Definitions

• the invention relates to a hand-held device for removing joint fillers, in particular joint sealing compounds, from joints with a grip area for a user's hand and a peeling element on the front.
• joints of tiles or tiles are often sealed with joint sealants, for example made of silicone.
• joint sealants for example made of silicone.
• a generic handheld device made of plastic has also become known, the front end of which has a peeling element which is formed by two differently shaped blade-shaped elements. It is necessary to first penetrate into the joint sealing compound with the first pointed blade-shaped element and to virtually score the joint sealing compound along the entire joint, this advantageously having to be done on both side edges of the joint. The hand-held device is then moved to a different position and the joint sealant thus removed from the joint is removed or peeled off with the second blade-shaped element. If this known handheld device already offers advantages over the above-described solutions, it is still in need of improvement.
• a generic hand-held device is also known from German utility model DE-U-94 22 011.
• This hand-held device has a blade at its tip which can be compressed to form a curved peeling element in accordance with the joint width to be machined.
• Another disadvantage of this known hand-held device is that a peeling effect can only be achieved with pushing operation.
• the object of the invention is to improve a generic handheld device so that both pulling and pushing operation is possible.
• the peeling element is a tapering peeling spout that is open on the back to form a further spout area is trained.
• the hand tool according to the invention is simply inserted into the joint in such a way that the two side flanks of the peeling nozzle lie approximately on the two surfaces adjacent to the joint and then the hand tool is preferably moved in a sliding manner along the joint, as a result of which the joint sealing compound is removed from the substrate in one step in the area of both joint flanks.
• the hand-held device can also be moved in a pulling manner without great effort, in this case too, the side flanks of the peeling nozzle then rest on both edge areas of the joint and ensure that the joint sealing compound is largely completely detached in one work step.
• the device is well suited for both left-handed and right-handed people without modification. Since there are no protruding sharp-edged cutting edges, there is practically no risk of injury to the operator. Due to the fact that the peeling spout is open on the back, detached joint sealing compound can emerge from the back of the hand-held device, so that it can be easily removed along an entire joint without interrupting the peeling process, because the detached mass can emerge from the back of the hand-held device.
• the device due to the formation of a further spout area at the rear end of the spout, the device can also be moved in a pulling manner, as a result of which a peeling through this spout area then takes place.
• the two side flanks of the peeling nozzle are arranged at an angle of approximately 65 ° to one another. This makes working easier, especially in corner areas, for example in joints between a floor and a wall surface.
• the handling can be significantly improved in that the peeling spout merges into a handling area at the end of the side flanks.
• the handling area is used, for example, to support the thumb of the user's hand on it, while the other fingers and the palm of the hand can be completely gripped in the grip area.
• the functionality of the hand-held device can be increased further by designing the end opposite the peeling spout as a spatula. With this spatula it is possible, for example, to remove the last residues of the joint sealant directly from smooth surfaces without the need for an additional spatula.
• the handling area and / or the handle area is provided with groove-shaped elevations for the thumb or a finger of a user's hand.
• the groove-shaped elevations in the handling area serve to position the thumb of the user's hand when the hand tool is used to actually remove the joint sealing compound from a joint, while the elevations in the handle area serve to position the thumb when the hand device is used as a spatula .
• the elevations are preferably formed in trough-shaped regions.
• the handheld device is made of plastic, if possible from a wear-resistant, stable plastic. This reliably avoids the risk of scratching the substrate adjacent to the joint.
• the handheld device can be manufactured simply and inexpensively. put.
• the handheld device can of course also consist of metal or other materials.
• FIG. 1 shows a section through a hand-held device according to the invention along line 1-l in FIG.
• FIG. 5 shows an enlarged detail marked with X in FIG. 1,
• FIG. 6 shows an enlarged detail identified by Y in FIG. 1,
• Fig. 8 is a section along the line Vlll-Vlll in Fig. 4 and
• a hand-held device for removing joint fillers, in particular joint sealing compounds from joints, is generally designated 1 in the drawing.
• This handheld device initially has a tapered grip area 2 which merges forwardly into a handling area 3 which is expanded compared to the tapered grip area 2.
• the handling area 3 ends at the front in a tapering peeling spout 4, the two side flanks of which are 4a and 4b are designated.
• These side flanks 4a and 4b are arranged approximately at an angle of 65 D to one another, as can be seen from FIG. 7.
• the side flanks merge into an angled area 4a 'or 4b' on the upper side and from this into side walls of the handling area 3.
• the underside 4u of the peeling spout 4 is preferably not straight, but rather slightly curved inward.
• the peeling spout 4 is also designed to be open on the back, this area is indicated by an arrow 5.
• the arc-shaped end region, which is open on the rear, forms a further spout region 4c, which also serves as a peeling element.
• the hand-held device 1 is designed as a spatula 6 at the end opposite the peeling spout 4, so that it can also be used as a spatula in addition to its peeling function.
• both the handling area 3 and the grip area 2 have groove-shaped elevations 7, 8 for the thumb or finger of a user's hand, which are formed in trough-shaped recessed areas 9, 10.
• the thumb or a finger rests on the groove-shaped elevations 7 and the other fingers grip the grip area 2 with the palm of the hand, while the thumb or a finger when using the hand-held device 1 with the spatula 6 groove-shaped elevations 8 rests and the remaining fingers and the palm encompass the handling area 3.
• the hand-held device 1 is used to remove a joint sealing compound from a joint with the front, pointed end of the peeling spout 4 into the joint sealing compound, and can then be moved along the joint to push it forward.
• the hand-held device 1 is directed toward the joint with its underside 1a.
• the handheld device 1 can also be pulled along the joint, the spout area 4c then acts as a peeling element.
• the handheld device 1 is preferably made entirely of plastic, preferably of a plastic that is resistant to wear and tear.
• the invention is not limited to the illustrated embodiment. Further configurations are possible without leaving the basic idea.
• the spatial arrangement of the side flanks 4a and 4b of the peeling spout 4 can also be selected differently, depending on the conditions of use, and the spatula 6 can of course also be omitted, for example.
