Description

Die Erfindung betrifft eine pinzettenartige Greifhilfe mit einstückig aus elastischem Material bestehenden, geraden Schenkeln, die zum hautkontaktfreien Dosieren von nach Art von Geschirrspülmaschinen-Reinigertabletten großformatig ausgebildeten Pulverpreßlingen an ihren Greiferflächen quer zur Schenkellängsrichtung verlaufende, gerade Greiferkanten besitzen.The invention relates to a tweezer-like gripping aid with straight legs consisting of one piece of elastic material, which have straight gripping edges on their gripper surfaces transverse to the longitudinal direction of the legs for the skin-contact-free dosing of powder compacts designed in the manner of dishwasher detergent tablets.

Im Bereich der Haushaltschemie sind konzentrierte Produkte und Wirkstoffe in Form großformatiger Pulverpreßlinge entwickelt worden. Beispielsweise werden kompaktierte Geschirrspülmaschinen-Reiniger anstelle von Pulver- oder Granulatformulierungen verwendet. Es werden auch Waschkraftverstärker bzw. -hilfsmittel und Reinigungsmittel, wie WC-Becken-Steine und Blauspüler für den Wasserkasten, als Konzentrat in Form gepreßter oder gegossener Körper aber auch als extrudierte Stränge zur Anwendung beim Endverbraucher geliefert. Bei all diesen Produkten ist es wünschenswert, den Anwender vor direktem Hautkontakt mit dem Wirkstoff zu schützen, weil die Produkte ätzende, klebende, stark färbende oder staubige Oberflächen besitzen können. Eine anwendungsfreundliche Verpackung der Produkte würde einen erheblichen Aufwand erfordern und damit nicht die erstrebte Einsparung bringen.Concentrated products and active ingredients in the form of large-sized powder compacts have been developed in the field of household chemistry. For example, compact dishwasher cleaners are used instead of powder or granule formulations. Detergent boosters, auxiliary agents and cleaning agents, such as toilet bowl stones and blue flushers for the water tank, are also supplied as a concentrate in the form of pressed or cast bodies, but also as extruded strands for use by the end user. With all of these products, it is desirable to protect the user from direct skin contact with the active ingredient, because the products can have caustic, adhesive, strongly staining or dusty surfaces. A user-friendly packaging of the products would require considerable effort and would not bring the desired savings.

In dem DE-GM 85 22 211 wird eine einfach aufgebaute und als Massenartikel preiswert herzustellende Greifhilfe beschrieben. Das bekannte Gerät ist gekennzeichnet durch zwei U-förmig über einen Steg miteinander. verbundene Greifwangen mit dem Produkttyp entsprechend profilierten Innenflächen und mit für einen sicheren Halt zwischen Daumen und Zeigefinger einer Hand ausgebildeten Außenflächen. Dieses Gerät ermöglicht zwar ein recht sicheres, flächiges und direktes Umgreifen oder punktuelles Umfassen eines tablettenförmigen Pulverpreßlings; bei ungeschicktem Fingerdruck kann das Produkt aber leicht zerbröckeln.DE-GM 85 22 211 describes a simply constructed gripping aid that is inexpensive to produce as a mass article. The known device is characterized by two U-shaped with each other via a web. connected gripping cheeks with the product type according to professional gelled inner surfaces and with outer surfaces designed for a secure hold between the thumb and index finger of one hand. Although this device enables a fairly secure, flat and direct gripping or selective gripping of a tablet-shaped powder compact; with unskillful finger pressure the product can easily crumble.

Dieses Problem ist besonders dann aktuell, wenn Pulverpreßlinge nach Art von sogenannten Vorspül-Reiniger-Tablettten (für Geschirrspülmaschinen) zu dosieren sind. Diese Produkte, die nicht - wie üblich - in ein Geschirrspülmaschinen-Dosierkästchen oder dergleichen gegeben und erst vor Beginn des Reinigungs-Programms in das Maschineninnere freigesetzt werden, sondern bereits zum Vorspülgang - also vor Programmbeginn - in den Innenraum der Geschirrspülmaschine, insbesondere Haushalts-Geschirrspülmaschine, an günstiger Stelle eingebracht werden sollen.This problem is particularly relevant when powder compacts are to be dosed in the manner of so-called pre-rinse cleaner tablets (for dishwashers). These products, which - as usual - are not put into a dishwasher dosing box or the like and are only released into the interior of the machine before the start of the cleaning program, but rather into the interior of the dishwasher, especially household dishwashers, during the pre-wash cycle - i.e. before the start of the program , should be introduced at a more convenient location.

Um zu erreichen, daß solche Vorspül-Reiniger-Tabletten schon durch die Einwirkung des Spülwassers leicht zerfallen, muß das Tablettenmaterial sehr weich sein; hartgepreßtes Material kommt nicht in Frage. Derart weiches Tablettenmaterial kann mit üblichen zangenartigen Greifhilfen beim Erfassen leicht so stark gepreßt werden, daß zumindest Teile der Tablette abbröckeln und zu Boden fallen. Zu dem Verlust an Reinigermaterial kommt hinzu, daß das agressive Tabletten material mit weiteren Hilfsmitteln vom Boden aufgehoben werden muß. Dem Ziel, eine sich möglichst leicht bereits im Vorspülgang auflösende Tablette zu schaffen, steht also das Problem entgegen, diese unverpackte Tablette unzerstört aus einem Vorratsbehälter an den vorgesehenen Platz in der jeweiligen Maschine zu transportieren.In order to ensure that such pre-rinse-cleaner tablets easily disintegrate due to the action of the rinsing water, the tablet material must be very soft; hard pressed material is out of the question. Such soft tablet material can easily be pressed so hard with conventional pliers-like gripping aids when grasping that at least parts of the tablet crumble and fall to the ground. In addition to the loss of cleaning material, the aggressive tablet material must be lifted from the floor with other aids. The aim of creating a tablet that dissolves as easily as possible in the pre-rinse cycle is countered by the problem of transporting this unpacked tablet undamaged from a storage container to the intended place in the respective machine.

Der Erfindung liegt die Aufgabe zugrunde, eine Greifhilfe zum hautkontaktfreien Dosieren von nach Art von Geschirrspülmaschinen-Reinigertabletten großformatig ausgebildeten, durch mechanischen Druck leicht zerfallenden Pulverpreßlingen zu schaffen, auf die beim Erfassen eines Pulverpreßlings in einem weiten Kraftbereich Druck auszuüben ist, ohne daß die Gefahr eines zu hohen Drucks an der Tablette und damit einer mechanischen Beschädigung besteht. Die erfindungsgemäße Lösung besteht für die pinzettenartige Greifhilfe mit einstückigen, geraden Schenkeln, die an ihren Greiferflächen quer zur Schenkellängsrichtung verlaufende, gerade Greiferkanten besitzen, darin, daß die Greiferflächen in Richtung auf einander zu aus der Schenkellängsrichtung federnd abgewinkelt sind.The invention has for its object a gripping aid to the skin To create contact-free dosing of large-format powder compacts designed in the manner of dishwasher detergent tablets, which easily disintegrate by mechanical pressure, to which pressure is to be exerted in a wide force range when a powder compact is grasped, without the risk of excessive pressure on the tablet and thus mechanical stress There is damage. The solution according to the invention for the tweezers-like gripping aid with one-piece, straight legs, which have straight gripper edges running on their gripper surfaces transversely to the longitudinal direction of the leg, is that the gripper surfaces are resiliently angled towards one another from the longitudinal direction of the leg.

Durch die erfindungsgemäß abgewinkelte Form der jeweils aus Schenkel und Greiferfläche bestehenden Arme der Greifhilfe im vorderen Greifbereich wird bei Zusammendrücken der Schenkel eine ausgleichende Federwirkung ausgelöst, die eine zu starke Anpressung am Produkt ausschließt. Mit anderen Worten heißt das, daß beim Zusammendrücken der Schenkel die Greiferflächen sich zunächst gleichlaufend auf einander zu bewegen, daß aber beim Inberührungkommen der Greiferflächen oder Greiferkanten mit der jeweiligen Tablette und weitererr Zusammendrücken der Schenkel der an die Greiferflächen angrenzende federnde Greiferwinkel zur Wirkung kommt mit der Folge, daß nur noch ein relativ kleiner Teil der insgesamt mit der Hand ausgeübten Kraft'bis zur Tablette durchdringt, weil der größere Teil der Kraft in erwünschter Weise - beim Strecken des federnden Winkels verbraucht wird.Due to the angled shape according to the invention of the arms of the gripping aid each consisting of legs and gripping surface in the front gripping area, a balancing spring action is triggered when the legs are compressed, which rules out excessive pressure on the product. In other words, when the legs are pressed together, the gripper surfaces initially move in synchronism with one another, but when the gripper surfaces or gripper edges come into contact with the respective tablet and further compresses the legs, the resilient gripper angle adjacent to the gripper surfaces comes into effect with the Consequence that only a relatively small part of the total force exerted by hand penetrates to the tablet, because the greater part of the force is consumed in the desired manner when the resilient angle is stretched.

Sowohl der zwischen den Armen aufgespannte Öffnungswinkel als auch der Dämpfwinkel zwischen Schenkel und Greiferfläche müssen nicht knickartig ausgebildet sein. In den Rahmen der Erfindung gehören auch mehr oder weniger gerundete Übergänge der im Bereich der Winkel aneinanderstoßenden Flächen.Both the opening angle spanned between the arms and the damping angle between the leg and the gripper surface need not be kink-like. The scope of the invention also includes more or less rounded transitions of the surfaces abutting one another in the area of the angles.

Gemäß weiterer Erfindung kann es günstig sein, wenn die abgewinkelten Greiferflächen etwa parallel zur Winkelhalbierenden des durch die Schenkel aufgespannten Öffnungswinkels verlaufen. Bei Anwendung liegen dann die Greiferflächen im wesentlichen flach an der anzuhebenden Tablette an.According to a further invention, it can be favorable if the angled gripper surfaces run approximately parallel to the bisector of the opening angle spanned by the legs. In use, the gripper surfaces then lie essentially flat on the tablet to be lifted.

Wenn stattdessen gewünscht wird, die Tablette nicht flächig sondern mit der vorderen, vorzugsweise geraden, Greiferkante des jeweiligen Schenkels berührend zu erfassen, werden die Greiferflächen mehr als parallel zu der Winkelhalbierenden abgewinkelt. Es kommt dann vorzugsweise eine Raumform in Frage, bei der die Greiferflächen größenordnungsmäßig um den Öffnungswinkel der Schenkel aus jeder Schenkellängsrichtung nach innen bzw. aufeinander zu abgewinkelt sind. Diese stärker abgewinkelte. Form der Alrme hat den Vorteil, daß die einen übermässigenDruck auf die Schenkel dämpfend aufnehmende Federwirkung des Winkels zwischen Schenkel und Greiferfläche der Arme der Greifhilfe theoretisch etwa maximal wird.If, instead, it is desired to grip the tablet not in a flat manner but in contact with the front, preferably straight, gripper edge of the respective leg, the gripper surfaces are angled more than parallel to the bisector of the angle. A spatial shape is then preferably possible in which the gripper surfaces are angled inwards or towards each other by the opening angle of the legs from each longitudinal direction of the leg. This more angled. A form of the l RME has the advantage that an excessive pressure on the leg receiving damping spring effect of the angle between the leg and the gripper surface of the arms of the gripping aid is about the theoretical maximum.

Grundsätzlich kann die erfindungsgemäße Greifhilfe aus beliebigem elastischem Material, wie Kunststoff oder Metall, bestehen. Aus Gründen des Aufwands für Material und Herstellung ist es günstig, Polypropylen einzusetzen.Basically, the gripping aid according to the invention can consist of any elastic material, such as plastic or metal. Due to the expense of material and manufacture, it is favorable to use polypropylene.

Anhand der schematischen Darstellung von Ausführungsbeispielen werden Einzelheiten der Erfindung erläutert. Es zeigen:

  • Fig. 1 eine Greifhilfe in perspektivischer Ansicht;
  • Fig. 2 ein Ausführungsbeispiel einer Greifhilfe im Schnitt;
  • Fig. 3 ein abgewandeltes Ausführungsbeispiel der Schnittdarstellung nach Fig. 2;
  • Fig. 4 eine Greifhilfe im Schnitt mit einer gegriffenen Tablette;
  • Fig. 5 eine stark zusammengedrückte Greifhilfe nach Fig. 4; und
  • Fig. 6 eine eine Tablette an deren Rundung erfassende Greifhilfe nach Fig. 4.
Details of the invention are explained on the basis of the schematic representation of exemplary embodiments. Show it:
  • Figure 1 is a gripping aid in a perspective view.
  • Figure 2 shows an embodiment of a gripping aid in section.
  • Fig. 3 shows a modified embodiment of the sectional view of Fig. 2;
  • Figure 4 is a gripping aid in section with a gripped tablet.
  • FIG. 5 shows a strongly compressed gripping aid according to FIG. 4; and
  • FIG. 6 shows a gripping aid according to FIG. 4 that detects a tablet on its curve.

Die in Fig.1 perspektivisch dargestellte Greifhilfe 1 besteht aus einem z.B. etwa 20 mm breiten und insgesamt 200 mm größenordnungsmäßig langen Band mit geraden Längskanten 2 und quer dazu verlaufenden geraden Endkanten bzw. Greiferkanten 3. Die Greifhilfe 1 besitzt auf der Mitte des sie bildenden Bandes einen federnden Öffnungswinkel 4 zwischen gleich langen, geraden Schenkeln 5. An die dem Winkel 4 gegenüberliegendenlängsenden der Schenkel 5 schließen sich über einen Dämpfwinkel 6 Greiferflächen 7 an.The gripping aid 1 shown in perspective in FIG. 1 consists of a e.g. about 20 mm wide and a total of 200 mm long with straight longitudinal edges 2 and transversely extending straight end edges or gripper edges 3. The gripping aid 1 has a resilient opening angle 4 on the middle of the band forming it between straight legs 5 of the same length the longitudinal ends of the legs 5 opposite the angle 4 adjoin gripper surfaces 7 via a damping angle 6.

Je nach der vorgesehenen Anwendung und Ausbildung der Greifhilfe 1 können die Innenflächen der Greiferflächen 7 profilartige Erhebungen 8, z.B. Rippen, Dornen, Stege oder Wülste, besitzen. Solche profilartigen Erhebungen 8 werden besonders dann gewünscht, wenn die Greiferflächen 7 bei Anwendung im wesentlichen flach an der anzuhebenden Tablette anliegen. Bei einer entsprechenden Greifhilfe 1 soll nach Fig. 2 der Dämpfwinkel 6 etwa gleich dem halben Öffnungswinkel 4 der Schenkel 5 gewählt werden. Wenn dagegen ein Erfassen der Tablette lediglich mit den Greiferkanten 3 der Greiferfläche7 gewünscht wird, sind die profilartigen Erhebungen 8 an sich nicht erforderlich, aber der Dämpf - winkel 6 soll größer als derjenige nach Fig. 2 sein. Er kann nach Fig. 3 beispielsweise in der Größenordnung des Öffnungswinkels 4 der Schenkel 5 liegen. Wenn also im vorliegenden Fall die Greiferfläche 7 im unbelasteten Zustand etwa parallel zur Winkelhalbierenden 9 des von den Schenkeln 5 aufgespannten Winkels 4 verläuft, soll die Greiferfläche 7 nach Fig. 3 weiter als parallel zu der Winkelhalbierenden 9 nach innen, das heißt in Richtung auf .den anderen Schenkel 5, abgewinkelt werden.Depending on the intended application and design of the gripping aid 1, the inner surfaces of the gripping surfaces 7 can have profile-like elevations 8, for example ribs, thorns, webs or beads. Such profile-like elevations 8 are particularly desired when the gripper surfaces 7 lie essentially flat against the tablet to be lifted when in use. With a corresponding gripping aid 1, according to FIG. 2, the damping angle 6 should be selected approximately equal to half the opening angle 4 of the legs 5. If, on the other hand, the tablet is only to be gripped with the gripper edges 3 of the gripper surface 7, the profile-like elevations 8 per se are not necessary, but the damping angle 6 should be greater than that of FIG. 2. According to FIG. 3, it can, for example, be of the order of magnitude of the opening angle 4 of the legs 5. If, in the present case, the gripper surface 7 runs approximately parallel to the bisector 9 of the angle 4 spanned by the legs 5 in the unloaded state, the gripper surface 7 according to FIG. the other leg 5, angled.

In Fig. 4 wird eine Greifhilfe 1 nach Fig. 3 im Schnitt mit einer ergriffenen Tablette 10 im Prinzip gezeichnet. Ein solcher Pulverpreßling zur Anwendung im -Vorspülgang einer Geschirrspülmaschine kann bei zylindrischer Ausbildung beispielsweise einen Durchmesser von 30 mm, eine Höhe von 22 mm und ein Gewicht von 25 g besitzen.In Fig. 4, a gripping aid 1 according to Fig. 3 is drawn in section with a gripped tablet 10 in principle. Such a powder compact for use in the pre-rinse cycle of a dishwasher can, for example, have a diameter of 30 mm, a height of 22 mm and a weight of 25 g with a cylindrical design.

Bei Anwendungder Greifhilfe 1 zum Anheben der Tablette 10 wird durch die gegenüber 'der Längsrichtung 11 der Schenkel 5 abgewinkelte Form der Greiferflächen 7 bei Fingerdruck in Pfeilrichtung 12 auf die Schenkel 5 eine ausgleichende Federwirkung ausgelöst, die ein zu starkes Anpressen der Greiferkanten 3 an der Tablette 10 in einem weiten Kraftbereich des in Pfeilrichtung 12 ausgeübten Drucks verhindert. Beispielsweise gibt Fig. 5 einen Hinweis darauf, daß eine stark zusammengepreßte Greifhilfe 1 zunächst im Bereich des Dämpfwinkels 6 selbst federnd der Druckkraft 12 nachgibt, bevor bei wesentlich höherem Druck in Pfeilrichtung 12 die Tablette 10 in Mitleidenschaft gezogen werden kann.When using the gripping aid 1 for lifting the tablet 10, the shape of the gripper surfaces 7, which is angled with respect to the longitudinal direction 11 of the legs 5, triggers a compensating spring effect upon finger pressure in the direction of the arrow 12 on the legs 5, which causes the gripping edges 3 to be pressed against the tablet too strongly 10 prevented in a wide force range of the pressure exerted in the direction of arrow 12. For example, Fig. 5 gives an indication that a strongly compressed gripping aid 1 initially yields itself resiliently in the region of the damping angle 6 to the compressive force 12 before the tablet 10 can be affected at much higher pressure in the direction of the arrow 12.

Im Ausführungsbeispiel nach Fig. 6 wird eine Greifhilfe 1 nach Fig. 4 dargestellt, die das sichere Erfassen einer zylindrischen Tablette 10 am Zylinderumfang, also in ungünstigster Position, darstellt. Die Greifhilfe 1 kann nämlich, wegen der geraden Greiferkanten 3 einerseits und wegen des federnden Nachgebens ihrer aus Schenkel 5 und Greiferfläche 7 zusammengesetzten Arme auch lose in eine Trommel oder dergleichen geschüttete Pülverpreßlinge erfassen und ohne die Gefahr des Zerbröckelns oder Abrutschens an den zur Anwendung vorgesehenen Ort, z.B. im Innern einer Geschirrspülmaschine, transportieren.In the exemplary embodiment according to FIG. 6, a gripping aid 1 according to FIG. 4 is shown, which represents the secure gripping of a cylindrical tablet 10 on the cylinder circumference, that is to say in the most unfavorable position. The gripping aid 1 can namely, because of the straight gripper edges 3 on the one hand and because of the resilient yielding of their leg 5 and gripper Surface 7 composite arms also loosely poured powder compacts poured into a drum or the like and transport them to the place intended for use, for example inside a dishwasher, without the risk of crumbling or slipping.

Durch die dargestellte, langgestreckte Bauform der im wesentlichen durch die Schenkel 5 gebildeten Arme der Greifhilfe 1 wird ferner erreicht, daß ohne Hautkontakt auch aus einer tiefen, zylindrischen oder rechteckigen Trommel Produkt zu entnehmen ist. Eine langgestreckte Bauform ist auch vorteilhaft beim Einlegen der jeweiligen Tablette in einen Maschineninnenraum, wenn die vorgesehene Arbeitsposition beispielsweise in der Mitte der Maschine liegt.The illustrated, elongated design of the arms of the gripping aid 1 essentially formed by the legs 5 also ensures that product can be removed from a deep, cylindrical or rectangular drum without skin contact. An elongated design is also advantageous when inserting the respective tablet into a machine interior if the intended working position is in the middle of the machine, for example.
