Description
Es gibt Gabelschlüssel, die sich selbsttätig passend zu den Schraubenköpfen oder Muttern in der Maulweite einstellen.There are open-ended wrenches that automatically fit the screw heads or Adjust the nuts in the mouth width.
Der Erfindungsgegenstand1 ist eine besondere Ausführungsform eines solchen Schlüssels und nachstehend näher beschrieben. Die Fig. ι stellt den Gabelschlüssel in einer Seitenansicht mit geschlossener Maulweite dar. Die Fig. 2 gibt eine Draufsicht ίο desselben Gegenstandes bekannt.The subject of the invention 1 is a particular embodiment of such a key and is described in more detail below. Fig. Ι shows the open-ended wrench in a side view with a closed mouth.
Die Fig. 3 stellt den Gabelschlüssel in einer Seitenansicht dar.Fig. 3 shows the open-ended wrench in a side view.
Der Gabelschlüssel α wird aus Stahlguß oder Schmiedeeisen hergestellt und ist zum
Anziehen für sechseckige, sowohl wie für viereckige Schraubenköpfe gleich gut geeignet.
. Wie aus Fig. 1 ersichtlich ist, wird die Maulöffnung, wie bekannt, mit beispielsweise
zehn oder mehreren Stahlplättchen el ausgefüllt, die unter Federdruck stehen. Die Anzahl
und die Dicke der Stahlplättchen kann je nach Größe des Schlüssels verschieden gewählt
und die Teilung nach einer Mutterlehre stufenweise eingerichtet werden.
Der Hohlraum c, der auch in seiner Breite die größte Maulweite des Gabelschlüssels darstellt,
ist mit den Stahlplättchen d ausgefüllt. Das .Neue besteht darin, daß jedes dieser
Stahlplättchen an einem Ende einen kleinen Stifte hat, auf welchem sich je eine Feder/
befindet, während der Stift e noch ein Stückchen in einer Bohrung g geführt wird. Statt
der bekannten Anordnung einer gemeinsamen Fed!er zum Vorschieben für alle Stahlplättchen
ist also hier nach der Erfindung jedes Stahlplättchen mit einer eigenen solchen Feder versehen.The open-end wrench α is made of cast steel or wrought iron and is equally suitable for tightening hexagonal and square screw heads.
. As can be seen from Fig. 1, the mouth opening is, as is known, filled with, for example, ten or more steel plates el which are under spring pressure. The number and thickness of the steel plates can be selected differently depending on the size of the key and the division can be set up in stages according to a mother gauge.
The cavity c, which also represents the largest opening of the open-end wrench in its width, is filled with the steel plate d. The new thing is that each of these steel plates has a small pin at one end, on which there is a spring /, while the pin e is guided a bit in a hole g. Instead of the familiar arrangement of a common Fed ! he for advancing all steel plates is provided here according to the invention each steel plate with its own such spring.
Die Stahlplättchen haben noch einen Hubbegrenzungsschlitz h, und durch diese Schlitze ist der kleine Bolzen i gesteckt, der in der unteren Schlüsselwange festgeschraubt ist und so die Stahlplättchen in ihrer äußersten Hubbegrenzung hält.The steel plates also have a stroke limiting slot h, and the small bolt i is inserted through this slot, which is screwed into the lower key cheek and thus holds the steel plate in its outermost stroke limitation.
Bei Anwendung des Gabelschlüssels für Muttern, die zur größten Maulweite des +5 Schlüssels passen, werden sämtliche Stahlplättchen beim Aufschieben auf die Mutter zurückgeschoben, während bei kleineren Muttern, wie beispiels\veise nach Fig. 3, nur diejenigen Stahlplättchen zurückgeschoben werden, die auf der Breite der Mutter oder des Schraubenkopfes liegen.When using the open-ended wrench for nuts that are larger than the +5 If you fit the key, all the steel plates will be pushed onto the nut pushed back, while with smaller nuts, as for example according to FIG. 3, only those steel plates are pushed back that are on the width of the nut or of the screw head.
Wird der Gabelschlüssel. von der Mutter entfernt, so schieben sich die Stahlplättchen selbsttätig durch' die kleinen Druckfedern / in ihre äußere Endstellung vor.Will the open-end wrench. from the mother removed, the steel plates push themselves through the small compression springs / in their outer end position.
