Abstract

1. A universal stepped wrench for radiator connection nipples or return flow nipples, having the following features : it has a square end (1) and an engagement end which, for inch measurement nipples, comprises in a sequence of reducing cross-section, a plurality of hexagonal stepped engagement portions (2, 3, 4, 5) formed with opposite grooves (6, 7, 8, 9) therein, the cross-section of the grooves being semi-circular, characterised by the following steps : at the engagement end, only hexagonal screw head shapes are provided for 1", 3/4", 1/2" and 3/8" nipples and approximately 14 mm, 10 mm, 20 mm and 15-16 mm are used as lengths ; the engagement portion for 1/2" nipples is stepped between thickness of 13.8 and 12 mm and the lengths of these steps are about 14 mm and 6 mm ; the grooves (6, 7, 8, 18, 9) are disposed at two opposite surfaces of the hexagon ; the width of the groove cross-section decreases from 5-6 mm in the case of the thickest engagement portion (2) to 3-3.5 mm at the thinnest portion (5).

Description

Die Erfindung bezieht sich auf einen Universalstufenschlüssel für Heizkörperverschraubungsnippel oder Rücklaufnippel mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a universal step wrench for radiator screw nipple or return nipple with the features of the preamble of claim 1.

Beim Ersatz von alten Ventilen in alten Heizkörpern müssen Nippel herausgeschraubt und passende Nippel wieder hereingeschraubt werden. Es kommen unterschiedliche Großen und Formen der Nippel vor, jedoch sind alle Nippel außen im Zollmaß gehalten. Zum Betätigen der Nippel weise diese im Inneren entweder einen Sechskant-Abschnitt - als Variante einen Doppelsechskantabschnitt, d. h. mit zwölf Ecken - oder zwei sich gegenüberstehende Nocken auf. Es kommen praktisch fünf unterschiedliche Sechskantgrößen und vier unterschiedliche Nockenzuordnungen vor, wobei der Abstand des jeweiligen Sechskants bwz. des Nockens vom dem freien Nippelende herstellerbedingten Schwankungen unterliegt. Zum Herausschrauben der Nippel mußte der Handwerker deshalb mehrere unterschiedliche Schlüssel bereithalten.When replacing old valves in old radiators, nipples must be unscrewed and suitable nipples screwed in again. There are different sizes and shapes of nipples, but all nipples are held on the outside in inches. To actuate the nipples, they either have a hexagon section inside - as a variant, a double hexagon section, i. H. with twelve corners - or two opposing cams. There are practically five different hexagon sizes and four different cam assignments, the distance between the respective hexagon or. the cam from the free nipple end is subject to fluctuations caused by the manufacturer. To unscrew the nipple, the craftsman had to keep several different keys ready.

Es sind bereits Versuche unternommen worden, die Vielzahl der Schlüssel zu reduzieren. Bei einem bekannten Werkzeug dieser oberbegrifflichen Art (DE-U1-8 011 130) sind neben drei sechskantigen Abschnitten für 3/4-, 1/2- und 3/8-zöllige Nippel noch ein kreiszylindrisches Basisteit für 1-zöllige Nippel mit Nocken vorgesehen. Angaben über die Längen der Eingriffsabschnitte sind nicht gemacht. Der Eingriffsabschnitt für 1/2-zöllige Nippel ist einheitlich durchgehend dargestellt. Es sind zwei durchlaufende Nuten von etwa 6 mm Breite in einander gegenüberliegenden Eckkanten der Eingriffsabschnitte vorgesehen. Nachteilig an dem bekannten Werkzeug ist der Umstand, daß es nicht für alle vorkommenden Nippel paßt und daß es wegen der Nuten in den Eckbereichen die Doppelsechskantäbschnitte der Nippel schlecht greift.Attempts have been made to reduce the number of keys. In a known tool of this generic type (DE-U1-8 011 130), in addition to three hexagonal sections for 3/4, 1/2 and 3/8 inch nipples, there is also a circular cylindrical base part for 1-inch nipples with cams . No details are given about the lengths of the engagement sections. The engagement section for 1/2-inch nipples is shown consistently throughout. There are two continuous grooves of about 6 mm in width in opposite corner edges of the engagement sections. A disadvantage of the known tool is the fact that it does not fit all nipples and that because of the grooves in the corner areas it does not grip the double hexagon sections of the nipple.

Bei einem weiteren bekannten Innensechskantschlüssel (DE-U1-7 919 953) ist ein Bedienungsteil mit einer axialen kantigen Aussparung zum Eingriff eines Bedienungswerkzeuges vorgesehen, oder das Bedienungswerkzeug muß unmittelbar an einem der Eingriffsabschnitte angesetzt werden. Es werden zwar vier sechseckige Eingriffsabschnitte für zöllige Nippel beschrieben, jedoch ist bei diesem Ausführungsbeispiel kein Vierkantende zum Angriff eines Ratschenschlüssels vorgesehen. Die Längen dieser Eingriffsabschnitte sind nicht angegeben. Der Eingriffsabschnitt für 1/2-zöllige Nippel ist einheitlich durchgehend dargestelJt. Die im Querschnitt rechteckförmig dargestellten Nuten können entweder in den Flächen oder in zwei gegenüberliegenden Eckkanten des Arbeitsteiles vorgesehen sein.In a further known Allen key (DE-U1-7 919 953), an operating part with an axial angular recess for engaging an operating tool is provided, or the operating tool must be attached directly to one of the engaging sections. Although four hexagonal engagement sections for imperial nipples are described, no square end for engaging a ratchet wrench is provided in this embodiment. The lengths of these engagement sections are not specified. The engagement section for 1/2-inch nipples is shown consistently throughout. The grooves shown rectangular in cross section can either be provided in the surfaces or in two opposite corner edges of the working part.

Der Erfindung liegt die Aufgabe zugrunde, einen Stufenschlüssel so zu gestalten, daß einerseits im wesentlichen sämtlichen in der Praxis vorkommenden Nippel erfaßt werden und andererseits die Gesamtlänge des Werkzeuges möglichst klein ist. Ferner sollen die Nuten die Funktion der Eingriffsabschnitte möglichst wenig beeinträchtigen, wenn es darum geht, Nippel mit doppeltem sechskantigem Innenmaß zu erfassen.The invention has for its object to design a step wrench so that on the one hand essentially all nipples occurring in practice are detected and on the other hand the total length of the tool is as small as possible. Furthermore, the grooves should impair the function of the engagement sections as little as possible when it comes to gripping nipples with a double hexagonal internal dimension.

Diese Aufgabe wird durch den Universalstufenschlüssel mit den Merkmalen des Anspruches 1 gelöst.This object is achieved by the universal step key with the features of claim 1.

Mit dem erfindungsgemäßen Universalstufenschlüssel braucht nicht lange versucht werden, ob der spezielle, in den Nippel eingeführte Schlüssel paßt, oder ob ein anderer Schlüssel versucht werden muß, vielmehr erweist sich das neue Werkzeug automatisch mit einer der Stufen als passend. Dabei können auch häufige Sonderformen von 1/2-zölligen Nippeln erfaßt werden. Die Arbeit kann so wesentlich beschleunigt werden.It does not take long to try with the universal step key according to the invention whether the special key inserted into the nipple fits or whether another key has to be tried; rather, the new tool automatically proves to be suitable with one of the steps. Frequent special forms of 1/2-inch nipples can also be detected. The work can be accelerated significantly.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung beschrieben. Dabei zeigt :

  • Figur 1 einen Stufenschlüssel, von der Seite gesehen ;
  • Figur 2 eine Ansicht in Richtung des Pfeiles II;
  • Figur 3 eine Ansicht in Richtung des Pfeiles III und
  • Figur4 einen Universalstufenschlüssel, in perspektivischer Darstellung.
An embodiment of the invention is described with reference to the drawing. It shows:
  • Figure 1 shows a step key, seen from the side;
  • Figure 2 is a view in the direction of arrow II;
  • Figure 3 is a view in the direction of arrow III and
  • Figure4 a universal step key, in perspective.

Der Stufenschlüssel nach Fig. 1 ist nicht in allen seinen Merkmalen Gegenstand der Erfindung und wird aus Offenbarungsgründen aufrechterhalten. Er besteht vorzugsweise aus gehärtetem Werkzeugstahl und weist ein Vierkantende 1 und daran anschließend vier Eingriffsabschnitte 2, 3, 4, 5 auf. Die Eingriffsabschnitte 2 bis 5 sind abgestuft, d. h., der dem Vierkantende 1 benachbarte Eingriffsabschnitt 2 hat den größten Querschnitt und der am weitesten entfernte Eingriffsabschnitt 5 hat den kleinsten Querschnitt. Die geometrische Form der Eingriffsabschnitte entsprechen Innensechskant-Schraubköpfen wie sie in Nippel von 1, 3/4, 1/2 und 3/8 Zoll vorkommen und folgende Abstände paralleler Flächen aufweisen : 22 mm (bei 1-zölligem Nippel) 16,8 mm (bei 3/4-zölligem Nippel), 13,8 mm verjüngend auf 12 mm (bei 1/2- zölligem Nippel) und 9,8 mm (bei 3/8-zölligen Nippel).The step key according to FIG. 1 is not the subject of the invention in all of its features and is maintained for reasons of disclosure. It preferably consists of hardened tool steel and has a square end 1 and then four engagement sections 2, 3, 4, 5. The engagement sections 2 to 5 are graded, i. that is, the engaging portion 2 adjacent the square end 1 has the largest cross section and the most distant engaging portion 5 has the smallest cross section. The geometric shape of the engagement sections corresponds to hexagon socket screw heads as they occur in nipples of 1, 3/4, 1/2 and 3/8 inches and have the following distances between parallel surfaces: 22 mm (with 1-inch nipple) 16.8 mm ( for 3/4 inch nipples), 13.8 mm tapering to 12 mm (for 1/2 inch nipples) and 9.8 mm (for 3/8 inch nipples).

Außerdem sind an zwei sich gegenüberliegenden Sechskantflächen jedes Eingriffsabschnittes 2 bis 5 jeweils eine in Achsrichtung sich erstreckende Nut 6, 7, 8, 9 vorgesehen. Die Achsen der Nutabschnitte 2 bis 5 fluchten zueinander, desgleichen die Nuten 6 bis 9. Die Nuten 6 bis 9 bilden gewissermaßen eine schräglaufende Rinne an der Außenseite der « Stufenpyramide », gebildet durch die Eingriffsabschnitte 2 bis 5.In addition, a groove 6, 7, 8, 9 extending in the axial direction is provided on two opposing hexagonal surfaces of each engagement section 2 to 5. The axes of the groove sections 2 to 5 are aligned with one another, as are the grooves 6 to 9. The grooves 6 to 9 form, as it were, an oblique groove on the outside of the “step pyramid”, formed by the engagement sections 2 to 5.

Die axialen Längen der Eingriffsabschnitte 2 bis 5 sind unterschiedlich groß gewählt, und zwar weist jeder Eingriffsabschnitt die minimale Länge auf, welche erforderlich ist, die Nocken in den praktisch vorkommenden Nippeln zu erfassen. Die Längen der Eingriffsabschnitte 2 bis 5, ohne Ubergangsschräge, vom Vierkantende 1 aus gesehen, betragen etwa 14 mm, 10 mm, 17 mm und 16 mm. Die Eingriffslänge des Werkzeuges (mit Ratschenschlüssel) beträgt etwa 87 mm. Die Nuten 6 bis 9 weisen etwa halbkreisförmigen Querschnitt auf, dessen Breite von 5 mm bei dem Eingriffsabschnitt 2 auf 3 mm beim Eingriffsabschnitt 5 abnimmt. Die Eingriffsabschnitte 2 bis 5 sind im übrigen leicht verjüngt ausgebildet, und zwar in der Reihenfolge ihrer Querschnittsabnahme, in Fig. 1 also von links nach rechts.The axial lengths of the engagement sections 2 to 5 are selected to be of different sizes, namely each engagement section has the minimum length which is necessary to grasp the cams in the nipples which occur in practice. The lengths of the engagement sections 2 to 5, without transition bevel, as seen from the square end 1, are approximately 14 mm, 10 mm, 17 mm and 16 mm. The length of engagement of the tool (with ratchet wrench) is approximately 87 mm. The grooves 6 to 9 have an approximately semicircular cross section, the width of which decreases from 5 mm in the engagement section 2 to 3 mm in the engagement section 5. The engagement sections 2 to 5 are otherwise designed to be slightly tapered, in the order in which they decrease in cross-section, ie from left to right in FIG. 1.

Das Vierkantende 1 ist 1/2-zöllig ausgebildet, d. h., die zueinander parallelen Seitenflächen weisen einen Abstand von 12,2 bis 12,7 mm auf. Ein derartiges Vierkantende kann in einen handelsüblichen Ratschenschlüssel eingesteckt werden, so daß eine bequeme Handhabung des Werkzeuges möglich ist. Zur Sicherung des Werkzeuges am Ratschenschlüssel kann ferner eine Rastkugel 10 vorgesehen sein, die in einer Bohrung des Vierkantendes 1 sitzt, durch eine eingelegte Feder nach außen gedrängt wird, jedoch die Bohrung nicht verlassen kann, weil der äußere Bohrungsrand verstemmt ist.The square end 1 is 1/2-inch, i. that is, the mutually parallel side surfaces are spaced from 12.2 to 12.7 mm. Such a square end can be inserted into a commercially available ratchet wrench, so that the tool can be handled comfortably. To secure the tool on the ratchet wrench, a locking ball 10 can also be provided, which sits in a bore of the square end 1, is pushed outwards by an inserted spring, but cannot leave the bore because the outer edge of the bore is caulked.

Das Werkzeug nach Fig. 4 unterscheidet sich von dem Stufenschlüssel nach Fig. darin, daß statt der Verjüngung von 13,8 mm auf 12 mm am Eingriffsabschnitt 4 eine weitere Stufe 14 vorgesehen ist. Die Eingriffsabschnitte (ohne Übergansschrägen) haben folgende Längen : 14 mm (für 1-zöllige Nippel), 10 mm (für 3/4-zöllige Nippel), 14 mm und 6 mm (Stufe 14) (für 1/2- zöllige Nippel) sowie 15 mm (für 3/8-zöllige Nippel). Die Gesamtlänge des Werkzeuges vor Aufstecken auf einen Ratschenschlüssel beträgt 82,5 mm ; bei aufgestecktem Ratschenschlüssel wird ein Freiraum (Arbeitsraum) von 87 mm Breite zwischen Nippel und Heizkörpernischenwand benötigt. Die sich längs erstreckenden Nuten 6, 7, 8, 18, 9 sind abgestuft tief und weisen eine Breite von 3 mm (Nut 9) bis 6 mm (Nut 6) bei halbkreisförmigen Querschnitt auf. Die Nutenachsen 6, 7, 8, 18, 9 sind in einer Querschnittsebene enthalten und entsprechend den Eingriffsabschnitten stufig gegeneinander versetzt.The tool according to FIG. 4 differs from the step wrench according to FIG. 4 in that instead of the taper from 13.8 mm to 12 mm, a further step 14 is provided on the engagement section 4. The engagement sections (without transition bevels) have the following lengths: 14 mm (for 1-inch nipples), 10 mm (for 3/4-inch nipples), 14 mm and 6 mm (step 14) (for 1/2-inch nipples) and 15 mm (for 3/8 inch nipples). The total length of the tool before being placed on a ratchet wrench is 82.5 mm; When the ratchet wrench is attached, a free space (work space) of 87 mm width is required between the nipple and the radiator recess. The longitudinally extending grooves 6, 7, 8, 18, 9 are stepped deep and have a width of 3 mm (groove 9) to 6 mm (groove 6) with a semicircular cross section. The groove axes 6, 7, 8, 18, 9 are contained in a cross-sectional plane and are staggered with respect to one another in accordance with the engagement sections.
