Definitions
- the invention relates to a coupling for connecting a broom or the like to a handle, consisting of a pin which can be connected to the broom and which has a latching configuration, and a sleeve which can be connected to the handle for receiving the pin and which has a lock which can be actuated from the outside against spring action having.
- broom handles which have a threaded part at one end which is screwed into an associated threaded hole in the broom.
- the durability of such a coupling depends on how tightly the threaded part is screwed into the associated threaded hole. Since the loads in the clutch area are very high, it is often observed that the clutch still comes loose.
- Couplings known from practice, of the type described at the outset, which are also referred to as plug-in couplings and in which the two coupling halves are connected to one another in that the pin is pushed into the sleeve until it engages, are therefore more advantageous. On the outside of the sleeve or on the stem there is a push button that holds the snap lock.
- the spring of the push button is also responsible for the force with which the latching formations are held in mutual positive engagement.
- the object of the invention is to provide a coupling of the type described above, which is easy to operate and which is characterized by a particularly secure, positive connection of the coupling halves.
- the grid is designed as a locking projection which is arranged on the free end of the pin on one long side, in that the pin on the opposite long side has a recess which reduces the height of the pin and extends over the width of the pin and the length of which is less than the insertion length of the pin in the sleeve, and that the sleeve has an inner cross section which is adapted to the largest pin cross section and which has on one side a latching recess for the latching projection and on the opposite side a longitudinally extending groove for a slot therein Tongue which extends into the inner cross section of the sleeve, the tongue being supported on an axial spring and being connected to a slide arranged on the outside of the sleeve and, in the locked state, gripping the pin on the longitudinal side opposite the latching projection.
- the security of the positive connection no longer depends on the strength of the spring.
- the pin is pushed into the sleeve until the front, free end meets the front of the tongue.
- the locking projection slides on an associated inside of the sleeve. Accordingly, the longitudinal axis of the pin can be tilted somewhat with respect to the longitudinal axis of the sleeve.
- the tongue is moved against the action of its axial spring until the latching projection can snap into the associated latching recess in the inner cross section of the sleeve.
- the tongue under the action of its axial spring, the tongue is pushed back into its starting position, underpinning the longitudinal side of the pin opposite the latching projection, which is thereby held in a form-fitting manner in the sleeve.
- the tongue is pulled back against the action of its axial spring with the aid of the outer slide until the pin is freely movable again and can be pulled out of the sleeve or falls out of the sleeve.
- the locking projection and / or the tongue can have associated bevels which prevent the tongue and the pin from tilting or blocking one another when the pin is inserted into the sleeve.
- the pin advantageously has a rectangular to square cross section.
- the inner cross section of the sleeve should have at least one longitudinally extending guide groove for a guide projection of the pin. The easiest way is when a guide pin is inserted into the pin, which is arranged outside the central plane of the pin. With appropriate Arrangement of the guide grooves, the pin can only be inserted into the sleeve in the correct position.
- the tongue can connect to a slide part guided in the sleeve, which is supported on the bottom of the sleeve via the axial spring, the slide part being connected to the outer slide part.
- the locking projection has a triangular to trapezoidal cross section and that the free end of the sleeve forms a stop for an abutment arranged on the pin, it is possible to prevent any axial play between the coupling halves in the coupled state.
- the coupling shown is used to connect a broom or the like, not shown, to a handle l, which consists of a metallic tube in the embodiment shown.
- a handle l which consists of a metallic tube in the embodiment shown.
- a sleeve 2 is inserted, the inner cross section of which is adapted to the largest cross section of a pin 3, which is connected to the broom or the like, not shown.
- the pin 3 has a rectangular to square cross section; it is designed as a hollow pin in the embodiment shown. In the region of its free end, the pin 3 has a locking projection 5 on a long side 4, which has a triangular cross section. On the opposite longitudinal side 6, part of the pin 3 is cut away, so that a recess 7 is formed which extends across the width of the pin 3 and whose length is slightly less than the insertion length of the pin 3 in the sleeve 2.
- the sleeve 2 has a locking recess 8 for the locking projection 5 of the pin 3 inserted into the sleeve 2.
- the catch recess 8 is opposite a zone 9 which is guided in an axial groove 10 of the sleeve 2.
- the tongue 9 adjoins a slide part 11 which is engaged by an axial spring l2 which is supported on a base l3 of the sleeve 2.
- a pin l5 extends through the slide part 11 and mutually opposite longitudinal slots l4 of the handle l into a slide l6 surrounding the handle l.
- the sleeve 2 has guide grooves 17 on the inside, which, as can be seen in particular from FIG. 3, are arranged off-center.
- the pin 3 is pushed into the sleeve 2, guide grooves l7 and guide pin l8 ensuring that the pin 3 is only in the correct position in the sleeve 2 can be introduced.
- the longitudinal axis of the pin 2 is pivoted somewhat with respect to the longitudinal axis of the sleeve 2 because the locking projection 5 of the pin 3 slides on the associated inside of the sleeve 2.
- the end face of the pin 3 also meets the tongue 9 and takes it along in the insertion direction against the action of its axial spring l2.
- the locking projection 5 reaches the area of the locking recess 8, it snaps into it.
- the tongue 9 is pushed back by its axial spring l2 back into its rest position, whereby it grips the longitudinal side of the pin 3 opposite the latching projection 5 in the region of the recess 7 and thus positively fixes the pin 3 in the sleeve 2.
- the outer slide l6 is moved against the action of the axial spring l2 until the tongue 9 releases the end of the pin 3. Then the pin 3 can be pulled out of the sleeve 2 or it falls out of the sleeve 2 automatically in a corresponding position.
- the tongue 9 on the one hand and the free end of the pin 3 on the other hand have associated bevels 19 and 20 which support the interaction of these components when they snap into place.
- the free end 2l of the sleeve 2 is designed as a stop for an abutment, not shown, arranged on the pin 3. With an appropriate arrangement of the abutment on the pin 3, the conditions can be set so that the insertion length of the pin 3 in the sleeve 2 is limited so that the triangular locking projection 5 only partially engages in the locking recess 8 and thereby prevents any axial play of the coupling half .

Abstract
Description
Die Erfindung betrifft eine Kupplung zum Anschluß eines Besens oder dergleichen an einen Stiel, bestehend aus einem mit dem Besen verbindbaren Zapfen, der eine Rastausbildung aufweist, sowie aus einer mit dem Stiel verbindbaren Hülse zur Aufnahme des Zapfens, die eine von außen gegen Federwirkung betätigbare Verriegelung aufweist.The invention relates to a coupling for connecting a broom or the like to a handle, consisting of a pin which can be connected to the broom and which has a latching configuration, and a sleeve which can be connected to the handle for receiving the pin and which has a lock which can be actuated from the outside against spring action having.
In der Praxis sind Besenstiele bekannt, die an einem Ende ein Gewindeteil aufweisen, das in eine zugeordnete Gewindebohrung des Besens eingedreht wird. Die Haltbarkeit einer solchen Kupplung hängt davon ab, wie fest das Gewindeteil in die zugeordnete Gewindebohrung eingedreht wird. Da die Belastungen im Kupplungsbereich sehr hoch sind, beobachtet man häufig, daß die Kupplung sich dennoch löst. Vorteilhafter sind deswegen aus der Praxis bekannte Kupplungen, der eingangs beschriebenen Gattung, die auch als Steckkupplung bezeichnet werden und bei denen die beiden Kupplungshälften dadurch miteinander verbunden werden, daß der Zapfen soweit in die Hülse geschoben wird, bis er einrastet. Außen an der Hülse oder am Stiel befindet sich ein Druckknopf, der die Rastverriegelung hält.In practice, broom handles are known which have a threaded part at one end which is screwed into an associated threaded hole in the broom. The durability of such a coupling depends on how tightly the threaded part is screwed into the associated threaded hole. Since the loads in the clutch area are very high, it is often observed that the clutch still comes loose. Couplings known from practice, of the type described at the outset, which are also referred to as plug-in couplings and in which the two coupling halves are connected to one another in that the pin is pushed into the sleeve until it engages, are therefore more advantageous. On the outside of the sleeve or on the stem there is a push button that holds the snap lock.
Die Feder des Druckknopfes ist aber auch dafür verantwortlich, mit welcher Kraft die Rastausbildungen im gegenseitigen Formschluß gehalten werden. Je größer die Sicherheit des Formschlusses sein soll, desto stärker muß die Feder ausgebildet sein und desto mehr Kraft ist zum Zusammenfügen bzw. zum Lösen der Kupplungshälften erforderlich.The spring of the push button is also responsible for the force with which the latching formations are held in mutual positive engagement. The greater the security of the positive connection, the stronger the spring must be and the more force is required to assemble or to release the coupling halves.
Aufgabe der Erfindung ist es, eine Kupplung der eingangs beschriebenen Gattung anzugeben, die sich leicht betätigen läßt und die sich durch besonders sicheren, formschlüssigen Verbund der Kupplungshälften auszeichnen.The object of the invention is to provide a coupling of the type described above, which is easy to operate and which is characterized by a particularly secure, positive connection of the coupling halves.
Diese Aufgabe wird dadurch gelöst, daB die Raster als Rastvorsprung ausgebildet ist, der am freien Ende des Zapfens auf einer Längsseite angeordnet ist, daB der Zapfen auf der gegenüberliegenden Längsseite eine die Höhe des Zapfens reduzierende Ausnehmnung aufweist, die sich über die Breite des Zapfens erstreckt und deren Länge kleiner ist als die Einschublänge des Zapfens in der Hülse, und daß die Hülse einen dem größten Zapfenquerschnitt angepaßten Innenquerschnitt hat der auf einer Seite eine Rastausnehmnung für den Rastvorsprung und auf der gegenüberliegenden Seite eine sich in Längsrichtung erstreckende Nut, für eine darin geführte Zunge aufweist, die bis in den Innenquerschnitt der Hülse ragt, wobei die Zunge auf einer Axialfeder abgestützt ist und mit einem auf der Außenseite der Hülse angeordneten Schieber verbunden ist sowie im Verriegelungszustand den Zapfen auf der den Rastvorsprung gegenüberliegenden Längsseite unterfaßt.This object is achieved in that the grid is designed as a locking projection which is arranged on the free end of the pin on one long side, in that the pin on the opposite long side has a recess which reduces the height of the pin and extends over the width of the pin and the length of which is less than the insertion length of the pin in the sleeve, and that the sleeve has an inner cross section which is adapted to the largest pin cross section and which has on one side a latching recess for the latching projection and on the opposite side a longitudinally extending groove for a slot therein Tongue which extends into the inner cross section of the sleeve, the tongue being supported on an axial spring and being connected to a slide arranged on the outside of the sleeve and, in the locked state, gripping the pin on the longitudinal side opposite the latching projection.
Bei dieser Kupplung hängt die Sicherheit des Formschlusses nicht mehr von der Stärke der Feder ab. Um die beiden Kupplungshälften miteinander zu verbinden, wird der Zapfen in die Hülse eingeschoben, bis sein vorderes, freies Ende auf die Stirnseite der Zunge trifft. Dabei gleitet der Rastvorsprung an einer zugeordneten Innenseite der Hülse. Dementsprechend kann die Längsachse des Zapfens gegenüber der Längsachse der Hülse etwas gekippt sein. Wenn die freie Stirnseite des Zapfens auf die Zunge trifft, wird die Zunge gegen die Wirkung ihrer Axialfeder soweit mitgenommen, bis der Rastvorsprung in die zugeordnete Rastausnehmnung im Innenquerschnitt der Hülse einschappen bzw. einrasten kann. Nunmehr wird die Zunge unter der Wirkung ihrer Axialfeder wieder in ihre Ausgangsstellung zurückgedrückt, wobei sie die dem Rastvorsprung gegenüberliegende Längsseite des Zapfens unterfaßt, der dadurch formschlüssig in der Hülse gehalten ist. Zum Lösen der beiden Kupplungshälften wird die Zunge mit Hilfe des äußeren Schiebers gegen die Wirkung ihrer Axialfeder zurückgezogen, bis der Zapfen wieder frei beweglich ist und aus der Hülse herausgezogen werden kann oder aus der Hülse herausfällt.With this coupling, the security of the positive connection no longer depends on the strength of the spring. To connect the two coupling halves to each other, the pin is pushed into the sleeve until the front, free end meets the front of the tongue. The locking projection slides on an associated inside of the sleeve. Accordingly, the longitudinal axis of the pin can be tilted somewhat with respect to the longitudinal axis of the sleeve. When the free end face of the pin meets the tongue, the tongue is moved against the action of its axial spring until the latching projection can snap into the associated latching recess in the inner cross section of the sleeve. Now, under the action of its axial spring, the tongue is pushed back into its starting position, underpinning the longitudinal side of the pin opposite the latching projection, which is thereby held in a form-fitting manner in the sleeve. To release the two coupling halves, the tongue is pulled back against the action of its axial spring with the aid of the outer slide until the pin is freely movable again and can be pulled out of the sleeve or falls out of the sleeve.
Zur Unterstützung des geschilderten Funktionsablaufs können der Rastvorsprung und/oder die Zunge einander zugeordnete Anlaufschrägen aufweisen, die verhindern, daß die Zunge und der Zapfen beim Einführen des Zapfens in die Hülse sich gegenseitig verkanten oder blockieren.To support the described functional sequence, the locking projection and / or the tongue can have associated bevels which prevent the tongue and the pin from tilting or blocking one another when the pin is inserted into the sleeve.
Der Zapfen weist zweckmäßig einen rechteckigen bis quadratischen Querschnitt auf. Um sicherzustellen, daß der Zapfen stets so in die Hülse eingeführt wird, daß sein Rastvorsprung in die zugeordnete Rastausnehmung fassen kann, sollte der Innenquerschnitt der Hülse wenigstens eine sich in Längsrichtung erstreckende Führungsnut für einen Führungsvorsprung des Zapfens aufweisen. Am einfachsten ist es, wenn in den Zapfen ein Führungsstift eingesetzt ist, der außerhalb der Mittelebene des Zapfens angeordnet ist. Bei entsprechender Anordnung der Führungsnuten kann der Zapfen stets nur lagerichtig in die Hülse eingeführt werden.The pin advantageously has a rectangular to square cross section. To ensure that the pin is always inserted into the sleeve so that its locking projection can reach into the associated locking recess, the inner cross section of the sleeve should have at least one longitudinally extending guide groove for a guide projection of the pin. The easiest way is when a guide pin is inserted into the pin, which is arranged outside the central plane of the pin. With appropriate Arrangement of the guide grooves, the pin can only be inserted into the sleeve in the correct position.
Die Zunge kann an ein in der Hülse geführtes Schieberteil anschließen, das über die Axialfeder an einem Boden der Hülse abgestützt ist, wobei das Schieberteil mit dem äußeren Schieberteil verbunden ist.The tongue can connect to a slide part guided in the sleeve, which is supported on the bottom of the sleeve via the axial spring, the slide part being connected to the outer slide part.
Wenn der Rastvorsprung einen dreieckförmigen bis trapezförmigen Querschnitt aufweist und daß freie Ende der Hülse einen Anschlag für ein am Zapfen angeordnetes Widerlager bildet, ist es möglich, jegliches axiale Spiel zwischen den Kupplungshälften im gekuppelten Zustand zu unterbinden.If the locking projection has a triangular to trapezoidal cross section and that the free end of the sleeve forms a stop for an abutment arranged on the pin, it is possible to prevent any axial play between the coupling halves in the coupled state.
Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; es zeigen:
- Fig. l einen Längsschnitt durch eine Kupplung entsprechend einen Schnitt in Richtung II durch den Gegenstand nach Fig. 2,
- Fig. 2 einen Schnitt in Richtung II-II durch den Gegenstand nach Fig. l,
- Fig. 3 einen Schnitt in Richtung III-III durch den Gegenstand nach Fig. l.
- 1 shows a longitudinal section through a coupling corresponding to a section in the direction II through the object according to FIG. 2,
- 2 shows a section in the direction II-II through the object according to FIG. 1,
- 3 shows a section in the direction III-III through the object according to FIG.
Die dargestellte Kupplung dient zum Anschluß eines nicht dargestellten Besens oder dergleichen an einen Stiel l, der bei der dargestellten Ausführung aus einem metallischen Rohr besteht. In den Stiel l ist eine Hülse 2 eingesetzt, deren Innenquerschnitt dem größten Querschnitt eines Zapfens 3 angepaßt ist, der mit dem nicht dargestellten Besen oder dergleichen verbunden ist.The coupling shown is used to connect a broom or the like, not shown, to a handle l, which consists of a metallic tube in the embodiment shown. In the
Der Zapfen 3 weist einen rechteckigen bis quadratischen Querschnitt auf; er ist bei der dargestellten Ausführung als Hohlzapfen ausgebildet. Im Bereich seines freien Endes weist der Zapfen 3 auf einer Längsseite 4 einen Rastvorsprung 5 auf, der einen dreieckförmigen Querschnitt besitzt. Auf der gegenüberliegenden Längsseite 6 ist ein Teil des Zapfens 3 weggeschnitten, so daß eine Ausnehmung 7 entstanden ist, die sich über die Breite des Zapfens 3 erstreckt und deren Länge etwas kleiner ist als die Einschublänge des Zapfens 3 in der Hülse 2.The
Die Hülse 2 weist eine Rastausnehmung 8 für den Rastvorsprung 5 des in die Hülse 2 eingeschobenen Zapfens 3 auf. Der Rastausnehmung 8 gegenüberliegend befindet sich eine Zone 9, die in einer axialen Nut l0 der Hülse 2 geführt ist. Die Zunge 9 schließt an ein Schieberteil ll an, an welchem eine Axialfeder l2 angreift, die auf einem Boden l3 der Hülse 2 abgestützt ist. Durch das Schieberteil ll und einander gegenüberliegende Längsschlitze l4 des Stiels l erstreckt sich ein Stift l5 bis in einen den Stiel l umgebenen Schieber l6.The
Die Hülse 2 weist innenseitig Führungsnuten l7 auf, die, wie man insbesondere aus Fig. 3 entnimmt, außermittig angeordnet sind. In die Führungsnuten l7 greifen die Enden eines Führungsstiftes l8 ein, der in den Zapfen 3 im Bereich seines freien Endes eingesetzt ist.The
Zum Verbinden des Besens mit dem Stiel l wird der Zapfen 3 in die Hülse 2 eingeschoben, wobei Führungsnuten l7 und Führungsstift l8 dafür sorgen, daß der Zapfen 3 nur in lagerichtiger Anordnung in die Hülse 2 eingeführt werden kann. Während des Einführens ist die Längsachse des Zapfens 2 etwas gegenüber der Längsachse der Hülse 2 verschwenkt, weil der Rastvorsprung 5 des Zapfens 3 auf der zugeordneten Innenseite der Hülse 2 gleitet. Deswegen trifft auch die Stirnseite des Zapfens 3 auf die Zunge 9 und nimmt diese gegen die Wirkung ihrer Axialfeder l2 in Einführrichtung mit. Wenn der Rastvorsprung 5 in den Bereich der Rastausnehmung 8 gelangt, rastet er in diese ein. Nunmehr wird die Zunge 9 von ihrer Axialfeder l2 wieder in ihre dargestellte Ruhestellung zurückgedrückt, wobei sie die dem Rastvorsprung 5 gegenüberliegende Längsseite des Zapfens 3 im Bereich der Ausnehmung 7 unterfaßt und damit den Zapfen 3 formschlüssig in der Hülse 2 festlegt.To connect the broom to the handle l, the
Zum Lösen der Kupplung wird der äußere Schieber l6 gegen die Wirkung der Axialfeder l2 soweit verschoben, bis die Zunge 9 das Ende des Zapfens 3 frei gibt. Dann kann der Zapfen 3 aus der Hülse 2 herausgezogen werden oder er fällt bei entsprechender Lage selbsttätig aus der Hülse 2 heraus.To release the clutch, the outer slide l6 is moved against the action of the axial spring l2 until the
Wie man insbesondere der Fig. 2 entnimmt, besitzen die Zunge 9 einerseits und das freie Ende des Zapfens 3 andererseits einander zugeordnete Anlaufschrägen l9 bzw. 20, die daß Zusammenspiel dieser Bauteile beim Einrasten unterstützen. Das freie Ende 2l der Hülse 2 ist als Anschlag für ein am Zapfen 3 angeordnetes nicht dargestelltes Widerlager ausgebildet. Bei entsprechender Anordnung des Widerlagers am Zapfen 3 können die Verhältnisse so eingerichtet werden, daß die Einschublänge des Zapfens 3 in der Hülse 2 so begrenzt ist, daß der dreieckförmige Rastvorsprung 5 nur teilweise in die Rastausnehmnung 8 einfaßt und dadurch jedes axiale Spiel der Kupplungshälfte unterbunden wird.As can be seen in particular from FIG. 2, the
