Definitions

  • This invention relates to a runner, in particular to a castor, with a locking device for arresting therunning and/or swivelling movement of the wheel, which castor has a back-set bearing pivot and back-set bearing through which passes an axially movable locking pin, on which pin a trip cam or the like acts.
  • centrally lockable castors which are especially intended for articles of furniture such as movable sick or hospital beds.
  • the centrally lockablecastors are generally actuated by means of a central locking device via rods or cable controls, which control trip cams or other members such as eccentrics, wedge or key systems for example, as disclosed in German Gebrauchsmuster Specification 1 928 153. 3
  • the invention obviates these disadvantages and provides a runner, in particular a castor, which even during assembly of the runner, can be accurately adjusted from the first so that subsequent adjusting operations, after the runner has been mounted in the frame of the bed or other article of furniture frame, is no longer necessary.
  • a runner in particular a castor, with a locking device for arresting the running and/or swivelling movement of 'the wheel, said runner having a back-set bearing and pivot, an axially movable locking pin passing through said bearing and pivot and a trip cam orjthe like arranged to act on saidlocking pin, wherein the trip cam or the like is arranged in a casing which encloses said pivot and the locking pin over substantially their entire extent, and which is a component part of the runner and forms a substantially smooth attachment plug by which the runner can be fitted into a tubular foot or the like.
  • the runner can be adjusted, during its assembly, in respect of the correct co-operation' of the trip cam and locking pin and is thus ready for installation, so that the tolerances of the bed frame or the like can no longer have a disadvantageous effect.
  • a particularly advantageous further development of the invention is characterized in that the trip cam or the like is supported in a casing composed of two half shells, which casing encloses the back-set bearing pivot and the locking pin substantially over their entire extent and which is a component part of the runner and forms the substantially smooth attachment plug for the fitting of the runner in a tubular foot of the like.
  • the invention offers among others the advantage that the wall thickness of the casing or of the casinghalf shells pushed over and enclosing the trip cam or the like can be varied in order to be able to use one and the same runner for fitting in tubular feet of different inner diameters.
  • the two casing shells can be provided at their lower end with an inner beading with which they engage in an outer groove of the back-set bearing pivot.
  • the two casing shells can be held together at their upper and lower ends by rings.
  • the lower retaining ring can act simultaneously as a tube end ring of the tubular foot.
  • the casing or the two casing shells can consist of metal or plastics or other suitable materials. Their construction as die-cast metal components is particularly advantageous.
  • the two casing shells consist of zinc die-castings.
  • the trip cam supported in the casing or two casing shells has a non-circular bore preferably with a flat on one side, in which the operating lever or the shift linkage can be inserted force-lockingly and fixed so as to rotate therewith, when the runner is fixed in the tubular foot of the bed frame of the like.
  • the bore of the trip cam can also however have a different profile which allows a control lever or shift linkage to be accommodated force-'lockingly and fixed so as to rotate therewith.
  • FIG. 1 shows the castor ready for installation, in section
  • FIG. 2 shows a detail of the arrangement of the trip cam in the casing, in lateral section
  • FIG. 3 shows only the casing of FIG. 1 composed of two half-shells, with the trip cam supported therein and with a control lever inserted, partly in section;
  • FIG. 4 shows the castor of FIG. 1 after its installation in a tubular foot, in section
  • FIG. 5 shows the arrangement of the trip cam in the casing after the insertion of the casing in the tubular foot, in lateral section.
  • the castor comprises a runner fork 2 holding a wheel 1 and a back-set bearing 3, which here is a swivel bearing and is composed of an outer ball cup 4, an inner ball cup 5 and balls 6.
  • a back-set bearing pivot 7 is fastened to the back-set bearing 3 in the usual manner by means of facetting and flanging.
  • a locking pin 8 is supported axially movably in the back-set bearing pivot 7, which pin is prevented from rotating by a lateral flat 9.
  • the locking pin 8 is mushroom-shaped and is provided at its lower end portion with a mushroom head 10, which can move axially together with the locking pin.
  • a pawl 11 is pivotably supported by means of a spindle 12.
  • Both the mushroom head of the locking pin 8 and the pawl l l have coinciding coni cal ratchet teeth 12 and 13, which mesh with one another when through actuation of the central locking device the trip cam 14 is rotated and thus presses on a cap nut 15 and consequently pushes the locking pin 8 downwards in its axial direction, in order to force the pawl 11 against the wheel 1.
  • the wheel 1 is arrested both in its swivelling movement and its rotary motion and thus the castor is completely locked.
  • the trip cam 14 is supported in the upper portion of a casing 16, which here encloses the back-set bearing pivot 7 and the back-set bearing pin 8 over their entire extent.
  • the casing 16 is a component part of the castor and forms an outwardly smooth attachment plug, by means of which the castor can be fitted into a tubular foot 24 (FIG. 4).
  • the casing 16 consists of two half-shells 16a and 16b which here enclose over their entire extent the back-set bearing pivot 7 and the locking pin 8.
  • the casing shells 16a and 16b have at their lower end an inner beading 17, with which they engage in an outer groove 18 of the back-set bearing pivot 7 and they are thereby connected to this latter axially immovable.
  • the casing shells 16a and 16b are held together by rings 19 and 20.
  • the lower retainer ring 20 acts simultaneously as a tube end ring of the tubular foot 24 (FIG. 4).
  • the two casing shells 16a and 16b and therefore the casing 16 formed therefrom are here diecast metal components and in this case consist of zinc die-castings, they could however just as well be pressed or injection moulded from a suitable plastics material.
  • the castor can be accurately adjusted during its assembly in respect of the co-operation of the trip cam 14 and locking pin 7 by means of the cap nut 15 and an associated lock nut 15a, so that the castor is ready for installation and will not need to be subsequently adjusted when it is inserted in the tubular foot 24 of the bed frame or other piece of furniture and is secured therein by means of a screw 25.
  • a runner preferably a castor, comprising a housing structure with an axis and a running wheel rotatable on said axis, a back-set bearing pivot arranged on said housing structure, an axially movable locking pin passing through the bearing pivot, trip camming means arranged to act on said locking pin, and securing means arranged in said housing structure to be acted on by said locking pin to lock the running and/or swivelling movement of the wheel
  • the improvement which comprises a casing enclosing said bearing pivot and locking pin over substantially their entire extent, and forming an integral component part of the runner, said trip camming means being movably but inlosably enclosed within said casing and supported in said casing and force connected to said locking pin and forming an integral component part of the runner, said casing forming a substantially smooth attachment plug by means of which the runner can be fitted in a tubular foot and the like and having near its upper end at least one horizontal bore which coincides with a bore of said trip camm
  • runner preferably a castor, as claimed in claim 1, which runner comprises a housing structure with an axis and a running wheel rotatable on said axis, a back-bearing pivot arranged on said housing structure, an axially movable locking pin passing through the bearing pivot, trip camming means arranged above the upper end of said bearing pivot to act on the head of said locking pin, and securing means arranged in said housing structure to be acted on by said locking pin to lock the running and/or swiveling movement of the wheel, wherein there are two half-shells forming a casing enclosing said bearing pivot and locking pin over substantially their entire extent, and forming an integral component part of the runner, said camming means being movably but inlosebly enclosed within said casing and supported in said casing above the upper end of said bearing pivot and force connected to said locking pin and being turnable in said casing for acting on the head of said locking pin and form ing an integral component part of the runner, said two half-shells
  • each halfshell has at its lower end an inner beading, and the back-set bearing pivot has an outer groove in which said headings engage.
