Description
[0026] The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show particularly preferred variants of the embodiment of the invention, but the invention is not limited thereto. The same reference numerals are used for the same components in the figures. In an exemplary and schematic manner [0027] FIG. 1 shows a side view of a kit with a first embodiment variant of a tool and a sanitary faucet; [0028] FIG. 2 shows a perspective view of the first embodiment variant of the tool and the sanitary faucet; [0029] FIG. 3 shows a sectional view of the first embodiment variant of the tool and the sanitary faucet; [0030] FIG. 4 shows a partial perspective view of the first embodiment variant of the tool; and [0031] FIG. 5 shows a side view of a second embodiment variant of the tool.
[0032] FIG. 1 shows a side view of a kit 15 with a first embodiment variant of a tool 1 and a sanitary faucet 3. The sanitary faucet 3 comprises a faucet body 16 having an outlet 18 with an outlet opening 17. The faucet body 16 can be attached to a support not shown here. A thermostatic mixer 21 of the sanitary faucet 3 shown in FIG. 3 can be supplied with hot water via a hot-water line 19 and with cold water via a cold-water line 20 shown in FIG. 2. The mixing valve 21 can be used to mix the cold water and the hot water to form a mixed warm water having a warm-water temperature. The warm water can then be fed to a mixing valve, which is also not shown here, through which the warm water can be mixed with cold water to form a mixed water having a desired mixed-water temperature. The mixed-water temperature and an extraction quantity of the mixed water can be adjusted by an actuating lever 22 of the sanitary faucet 3. The tool 1 has a shaft 4 extending along a longitudinal axis 5 of the tool 1. Furthermore, the tool 1 has a tool length 23 along the longitudinal axis 5. A drive geometry 6 is formed at a first longitudinal end 24 of the tool 1, and an actuating handle 26 is formed at an opposite second longitudinal end 25, by means of which a user can rotate the tool 1 about the longitudinal axis 5. The longitudinal axis 5 therefore simultaneously represents an axis of rotation of the tool 1.
[0033] FIG. 2 shows an enlarged view of the first embodiment variant of the tool 1 of the sanitary faucet 3 in the area of an assembly opening 27 of the faucet body 16, after the tool 1 has been connected to an adjustment element 2 of the sanitary faucet 3 shown in FIG. 3. The shaft 4 of the tool 1 comprises a plurality of plates 14, wherein adjacent plates 14 are rotated by 90° with respect to one another about the longitudinal axis 5. The individual plates 14 have a length 28, a width 29 and a thickness 30. At the second longitudinal end 25 of the tool 1, the actuating handle 26 having an outer corrugation 31 can be seen.
[0034] FIG. 3 shows a sectional view of the first embodiment variant of the tool 1 and the sanitary faucet 3. The drive geometry 6 of the tool 1 is inserted through the mounting opening 27 of the faucet body 16 onto a screw head 32 of an adjustment element 2 of the sanitary faucet 3. In this case, the adjustment element 2 is designed in the shape of a bolt, which is bolted into a threaded sleeve 33. The threaded sleeve 33 is supported in a body adapter 34 of the faucet body 16. The adjustment element 2 has a stop surface 35 for an expansion element 36 at its end opposite the screw head 32. The expansion element 36 can expand in an axial direction 37, i.e., in parallel to the longitudinal axis 5 of the tool 1 or of the adjustment element 2, as a function of the mixed-water temperature of the mixed water, and in so doing adjust a gate valve 39 in the axial direction 37 via a connecting element 38. The gate valve 39 can be used to adjust a hot water gap for the hot water and a cold-water gap for the cold water, which gaps are not shown here, such that a mixing ratio of the hot water and the cold water and thus a warm-water temperature of the warm water mixed from the hot water and cold water can be adjusted by the gate valve 39. By rotating the tool 1 about the longitudinal axis 5, the stop surface 35 and thus the expansion material element 36 can be adjusted in the axial direction 37. In this way, the thermostatic mixing valve 21 can be used to adjust a maximum warm-water temperature of the mixed warm water. After the warm-water temperature has been adjusted, the tool 1 can be pulled off again from the adjustment element 2.
[0035] FIG. 4 shows a perspective view of the first embodiment variant of the tool 1 in the area of its drive geometry 6. The drive geometry 6 is formed at the first longitudinal end 24 of the tool 1 in the manner of a hexagon socket 7 and is fitted onto the bolt head 32 of the adjustment element 2. In this way, a torque can be transferred to the adjustment element 2 and the tool 1 can be used to rotate the adjustment element 2 about the longitudinal axis 5. The drive geometry 6 comprises a first drive jaw 8 and a second drive jaw 9, which have a (substantially) C-shaped and/or ring-segment-shaped cross-section orthogonal to the longitudinal axis 5. The drive jaws 8, 9 are separated from each other by a first slot 10 and second slot 11, which continue in parallel to the longitudinal axis 5 into the adjacent plate 14 of the shaft 4 of the tool 1, where they open into a drilled hole 40. When a predetermined torque is reached during the actuation of the adjustment element 2, the drive jaws 8, 9 spread elastically outwards in a radial direction 41 (i.e., orthogonally to the longitudinal axis 5) such that the drive geometry 6 slips in a circumferential direction 42 about the longitudinal axis 5 over the screw head 32 of the adjustment element 2, in that way preventing damage to the expansion material element 36 and/or the threaded sleeve 33 shown in FIG. 3. A first opening 12 is also formed in the first drive jaw 8 and a second opening 13 is formed in the second drive jaw 9, which increases the flexibility of the drive jaws 9, 10. Furthermore, it can be seen in FIG. 4 that adjacent panels 14 of the shaft 4 overlap in an overlap region 43 in parallel to the longitudinal axis 5.
[0036] FIG. 5 shows a side view of a second embodiment variant of the tool 1 in the region of its first longitudinal end 24. The second embodiment variant of the tool 1 differs from the first embodiment variant of the tool 1 only in that the first opening 12 of the first drive jaw 8 of the drive geometry 6 and the second opening 13 of the second drive jaw 9 of the drive geometry 6 are not orthogonal to the longitudinal axis 5, but are oblique. In this way, the torque, at which the drive jaws 8, 9 spread elastically outwards in the radial direction 41 and the drive geometry 6 disengages from the screw head 32 of the adjustment element 2, can be changed compared to the first embodiment variant of the tool 1. In all other respects, the second embodiment variant of the tool 1 is configured identically to the first embodiment variant of the tool 1.
[0037] This invention can prevent damage to a sanitary faucet.
