Description

Verschiebbare Doppelrolle mit BremsklotzMovable double roller with brake block

Die Neuerung bezieht sich auf eine Doppelrolle, vorzugsweise fixr Kranken- u. o. Pflegebetten, die über einen mit der Außenhülse (12) fest verbundenen Stab (4) mit einem Bremsklotz (5) über einen Schaltnocken (14) aus der Außenhülse (12) so weit ausfahrbar ist, bis der Stab (4) mit dem Bremsklotz (5) keinen Bodenkontakt mehr hat.The innovation relates to a double roller, preferably fixed for hospital or nursing beds, which can be extended from the outer sleeve (12) via a rod (4) firmly connected to the outer sleeve (12) with a brake block (5) via a switching cam (14) until the rod (4) with the brake block (5) no longer has contact with the ground.

Es sind Laufrollen bekannt, die in der Schwenk- und Laufrichtung feststellbar sind. Diese Laufrollen sind sehr kostenintensiv gefertigt und haben den Nachteil, daß sowohl im festgestellten als auch im beweglichen Zustand nur eine geringe Standfläche gegeben ist.There are known castors that can be locked in the swivel and running direction. These castors are very expensive to manufacture and have the disadvantage that they only have a small footprint when locked or when moving.

Der Neuerung liegt die Aufgabe zugrunde, eine Laufrolle so zu gestalten, daß dieThe innovation is based on the task of designing a roller in such a way that the Standfläche vergrößert wird und bei Nichtbenutzung der Laufrolle diese entlastet ist.The standing area is increased and the load on the castor is reduced when it is not in use.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die unter Federvorspannung stehende Laufrolle über einen feststehenden Stab (4), der mit der Außenhülse (12) verbunden ist, schiebbeweglich über einen Schaltnocken (14) so weit nach unten gedrückt wird, bis der Stab (4) mit dem Bremsklotz (5) keinen Bodenkontakt mehr hat.This object is achieved according to the invention in that the spring-loaded roller is pressed downwards via a fixed rod (4) which is connected to the outer sleeve (12) and is slidably pushed via a switching cam (14) until the rod (4) no longer has contact with the ground with the brake block (5).

Die Neuerung ist in den Zeichnungen dargestellt und wird im folgenden Text näher beschrieben:The innovation is shown in the drawings and is described in more detail in the following text:

Fig. 1: Schnittzeichnung einer Laufrolle mit Bremsklotz (5), wobei der Fig. 1: Sectional drawing of a roller with brake block (5), where the

Bremsklotz (5) Bodenkontakt hat; die Doppel-Laufrolle (1) ist durch die
Druckfeder (10) nach oben gedrückt.Brake pad (5) has ground contact; the double roller (1) is
Compression spring (10) pressed upwards.

Fig. 2: Doppel-Laufrolle (1) in einer Rückansicht, wobei der Bremsklotz (5) Fig. 2: Double roller (1) in a rear view, with the brake block (5)

Bodenkontakt hat.has contact with the ground.

Fig. 3: Doppel-Laufrolle (1) in einer Rückansicht, wobei die Laufrollen (1) Fig. 3: Double roller (1) in a rear view, with the rollers (1)

Bodenkontakt haben.have contact with the ground.

Der Rollenträger (2), vorzugsweise aus einer Zink-Druckguss-Legierung oder aus Kunststoff bestehend, nimmt über den Rollenbolzen (3) die beiden vorzugsweise aus Kunststoff gefertigten Laufrollen (1) auf, die jeweils mit einem Ring fixiert werden.
Auf dem Ansatz des Rollenträgers (2) ist zweckmäßig ein Drucklager (7) installiert, wobei die Schiebehülse (8) über den Ring (6) drehbeweglich mit dem Rollenträger (2) verbunden ist. Der Stab (4) mit dem Bremsklotz (5) ist über den Querstift (11) mit der Außenhülse (12) fest verbunden. Die in der Schiebehülse (8) über dem Querstift (11) eingesetzte Druckfeder (10) schiebt die Schiebehülse (8) mit dem Rollenträger (2) und den Laufrollen (1) nach oben, sobald der Schaltnocken (14) geschwenkt wird.
Die Laufrolle ist entlastet [Fig. I].The roller carrier (2), preferably made of a zinc die-cast alloy or of plastic, receives the two rollers (1), preferably made of plastic, via the roller bolt (3), which are each fixed with a ring.
A thrust bearing (7) is conveniently installed on the attachment of the roller carrier (2), whereby the sliding sleeve (8) is connected to the roller carrier (2) via the ring (6) in a rotationally movable manner. The rod (4) with the brake block (5) is firmly connected to the outer sleeve (12) via the cross pin (11). The compression spring (10) inserted in the sliding sleeve (8) above the cross pin (11) pushes the sliding sleeve (8) with the roller carrier (2) and the rollers (1) upwards as soon as the switching cam (14) is pivoted.
The roller is unloaded [Fig. I].

Bei Fahrbarmachung der Laufrolle (1) wird der Schaltnocken (14) im Uhrzeigersinn geschwenkt. Die Schiebehülse (8) mit dem Rollenträger (2) und den LaufroUen (1) wird so weit nach unten gedrückt, bis der Bremsklotz (5) keinen Bodenkontakt mehr hat, wobei die Schlitze (13) in der Schiebehülse (8) die senkrechte Führung übernehmen.When the roller (1) is made mobile, the control cam (14) is pivoted clockwise. The sliding sleeve (8) with the roller carrier (2) and the rollers (1) is pressed downwards until the brake block (5) no longer has contact with the ground, whereby the slots (13) in the sliding sleeve (8) take over the vertical guidance.

Die Bewegung des Schaltnocken (14) wird zweckmäßig über einen nicht näher beschriebenen Hebel erfolgen, der mit der Schaltachse (15) verbunden ist.
Der drehbewegliche Bremsklotz (5) schwenkt mit der Laufrolle, so daß eine große Standfestigkeit zu jedem Zeitpunkt gegeben ist.The movement of the switching cam (14) is expediently carried out via a lever (not described in more detail) which is connected to the switching axis (15).
The rotating brake block (5) pivots with the roller so that a high level of stability is ensured at all times.
