Description

Technical environment

[0001] The invention relates to a storage and metering device for multi-purpose lubricating greases, a storage and metering device for multi-purpose lubricating greases with a tubular receiving container for the multi-purpose lubricating grease, which is provided with a bottom part and a removable lid, as are used in almost every craft or industrial workshop. State of the art

[0002] Here you will often find simple cans of lubricating grease, from which portions of grease can be taken as needed using more or less suitable utensils, such as brushes.

[0003] The cans are often unsealed, so contamination of the contents is not an occasional occurrence. Furthermore, the brushes used often sink into the lubricant, meaning that excess lubricant must first be removed before the brush can be applied evenly to the desired area in a later step.

[0004] To ensure a predetermined supply of lubricants, particularly to machines, lubricant dispensers equipped with an electric motor drive are known from the prior art, for example from DE 44 22 407 A1 D, which can be adjusted to supply a predetermined quantity of lubricant to a suitable location on a machine.

[0005] In addition, manually operated grease guns are of course known, which can be used by qualified personnel to supply lubricant to bearings, spindles and the like via grease nipples. Object of the invention

[0006] Based on the problem described above, the object of the invention is not to improve the described partially machine-driven lubricant dispensing devices, which have of course proven themselves in practice.

[0007] Rather, the aim of this invention is, in principle, to improve and replace the grease dispensers described above, so that contamination of the lubricants is avoided, easy intuitive dosing and removal of the lubricant is ensured, and the removal instrument has its fixed place on the novel storage and dosing device. Solution to the task

[0008] According to the invention, the problem set for a storage and dosing device with the features described in the generic part of claim 1 is solved by the technical teaching described in the characterizing part of the main claim.

[0009] The essential feature of the invention is that a rotatable threaded spindle is arranged in the interior of the receiving container, which is rotatably mounted in the base of the receiving container, pointing vertically upwards towards the lid, and extends through a closure part arranged below the lid. A piston is mounted on the threaded spindle and is movable translationally upwards and downwards on it. Above the piston, in the area of ​​the interior located there, the multi-purpose lubricating grease intended for removal is introduced. The closure part has a plurality of recesses arranged on a concentric ring around the threaded spindle, and an actuating element for rotating the threaded rod and for translationally moving the piston is fixed on the threaded rod above the closure part on the outside of the storage and dosing device.

[0010] The design according to the invention makes it possible to store the required multi-purpose lubricating grease in a closed container and, when required, to push a metered quantity of this multi-purpose lubricating grease upwards out of the receiving container through the recesses arranged in the closure part by means of a rotation of the actuating element on the outside of the storage and metering device by means of the piston inside which is movable translationally in height by the threaded spindle, where the lubricating grease can then be picked up for further use by suitable removal devices such as a brush.

[0011] If the storage and dosing device is not in use, the recesses on the top can be covered by placing the existing lid on top, thus reliably preventing contamination of the multi-purpose lubricating grease when not in use.

[0012] Specific embodiments of the subject matter of the invention result, in conjunction with the technical teaching of the main claim, additionally from the features of the dependent claims relating back to the main claim.

[0013] In practice, it has proven advantageous if the recesses arranged in a concentric ring around the threaded spindle open into a groove-shaped depression on the outer side of the locking element, facing away from the interior. Using the brush typically used to remove multi-purpose grease, the groove-shaped depression can easily be brushed around the threaded spindle to remove the grease that has been squeezed out of the recesses.

[0014] To ensure consistently reliable translational movement of the piston, it has also proven advantageous to arrange two opposing receptacles on the inside of the base, concentrically around the threaded spindle. These receptacles accommodate guide columns inserted into each guide column. The guide columns project vertically upwards into the interior of the reservoir towards the closure and each passes through a bore of the piston. The guide columns prevent the piston from rotating when the threaded spindle is turned simultaneously, thus ensuring reliable linear movement of the piston upwards or downwards even with varying viscosities of the lubricating grease located in the interior above the piston.

[0015] With regard to cost-effective manufacturing of the device according to the invention, to ensure a long service life and easy handling or filling, it has proven advantageous to manufacture the receiving container from aluminium and to screw it to the base part and the closure part, which are made of plastic.

[0016] To store a brush, mentioned above and intended as a grease dispensing device, directly on the invention when not in use, it has proven advantageous to provide a blind hole on the upper side of the actuating element facing away from the receiving container. The handle of the brush can be inserted into this blind hole, with the depth of the blind hole being in the range of 20 to 40 mm and the diameter in the range of 10 to 20 mm. Character description

[0017] An embodiment of the invention is explained in more detail below with reference to the accompanying drawing. The figure shows a cross-sectional view through the storage and dosing device according to the invention, from which all essential details of the internal structure and operation of the invention can be seen.

[0018] The invention comprises a receiving container 1, preferably made of aluminum and cylindrical in shape, defining an interior 15. The receiving container 1 is equipped with a base 2 at its underside, which is screwed to the receiving container. This is preferably done by means of lateral screws (not shown in detail), with each screw engaging a threaded hole on the side of the base 2 through a through-hole in the lower region.

[0019] In the center of the base section 2 is a bearing point 9 in the form of a bore, into which a threaded spindle 4 is arranged vertically upwards into the interior 15 of the receiving container 1. At its lower free end, the threaded spindle 4 is secured by means of a snap ring 25.

[0020] On the upper side of the receiving container, facing away from the base part 2, it is equipped with a closure part 5. A bore 6 is provided in the center of this closure part 5, through which the threaded spindle 4 passes, so that the upper free end of the threaded spindle 4 protrudes from the receiving container.

[0021] An actuating element 20 is fixed to this upper free end of the threaded spindle 4, which serves to rotate the threaded spindle 4. To facilitate actuation, a knurling 21 is located on the outside of the actuating element 20.

[0022] Inside the interior 15 of the receiving container 1, a piston 7 is mounted on the threaded spindle 4 in a threaded bore 26. In addition to the threaded bore 26, the piston 7 has two bores 11 and 12 arranged diametrically opposite each other on a concentric circle. These bores 11 and 12 each extend through a column 23 and 24, which are inserted into receptacles 13 and 14 in the base 2 of the device according to the invention. When the threaded spindle 4 is rotated, the columns 23 and 24 prevent the piston 7 from rotating simultaneously, so that the rotation of the threaded spindle 4 only allows the piston to move upwards and downwards in a straight line.

[0023] The piston 7 is sealed off from the inner wall of the receiving container 1 by means of a seal 10. As can be seen from the drawing, the piston 7 defines a larger or smaller upper section 16 and lower section 17 of the interior 15, depending on its position.

[0024] Multi-purpose grease is introduced into the upper section 16. Prior to this, the piston 7 is moved to its lower position, where it rests against the top of the base section 2. To introduce the grease into the upper section 16 of the interior, the closure part 5 is separated from the reservoir 1. After filling, the closure part 5 is placed onto the reservoir 1. When the threaded spindle 4 is then turned, the piston 7 moves upwards from its lower position and forces the multi-purpose grease present in the upper section 16 of the interior 15 upwards. There, it is metered according to the movement of the piston 7 and emerges through recesses 18 in the form of through-holes arranged concentrically around the threaded spindle 4 in the closure part 5.

[0025] On the outside of the closure part 5, an annular recess 19 in the form of a groove is provided in the area of ​​the bores 18. The squeezed-out multi-purpose lubricating grease can be dispensed from the recess 19 in a measured amount using a brush.

[0026] When the storage and dosing device according to the invention is not in use, a lid 3 is placed on the top of the receiving container 1. The lid 3 has a recess in the center of this recess, the diameter of which is slightly larger than the outer diameter of the actuating element 20, so that the lid 3 can be placed over the actuating element 20 onto the top of the receiving container 1 or the closure part 5. The outer surface of the lid 3 is provided with downward-facing bends at right angles, which ensure a secure fit of the lid 3 on the receiving container 1.

[0027] The brush typically used for removing the lubricating grease from the recess 19 can be inserted directly into a blind hole 22 on the top of the actuating element 20 of the device. It is thus always readily available. The blind hole 22 is designed to accommodate various brush handles, advantageously with a diameter of 10 to 20 mm and a depth of 20 to 40 mm.

[0028] The inventive design of the storage and dosing device for multi-purpose lubricating greases fulfills, as described above, all the requirements of cost-effective manufacturing and easy handling; moreover, the features of the invention ensure a long service life.

[0029] Naturally, one does not move outside the scope of protection of the invention if individual aspects of the described exemplary embodiment of the storage and dosing device according to the invention are implemented in a technically different, but equivalent manner.
