Definitions

  • the invention relates to a fitting, more specifically to a device for detachably suspending a sliding door from a guide rail, having a hanger member guided in the guide rail and a body member formed to be flushmounted in a recess at the top of the sliding door and conneetable to the sliding door, whereby the weight of the sliding door is suspended from the guide rail via the holder and hanger members.
  • One known fitting of this type is formed by a plateshaped web having at its one end a headpiece and at its other end a foot piece.
  • the head piece is designed as a slider and has shoulders symmetrically to its longitudinal center plane by means of which the slider bears on the flanges of a D-shaped rail.
  • the footpiece provided at the-bottom endof the web is formed as a cylinder and much thicker'than the web.
  • the thickness or rather depth of this cylinder is such that its one flat end coincides with the web and its other end which is also flat extends into a recess at the top end of the sliding door leaf.
  • This latter flat end and the adjoining cylindri cal portion extend into the recess deep enough to provide a support for the sliding door leaf.
  • the recess in the top end of the sliding door is formed as a cylindrical hole and made with a slightly larger diameter than the cylinder.
  • the web which connects the head piece with the foot piece of the fitting is recessed in a vertical slot extending from the cylindrical hole to the top edge of the door leaf.
  • the web is provided with a hole above the cylinder to receive a screw to be driven into the door.
  • the web is formed with a half-round lug at a point above the cylinder to assist alignment which lug extends into a further recess at the edge of the door leaf to the same depth as the cylinder.
  • the screw serving to fasten the web to the door leaf is inserted into a projection between the cylinder and the lug.
  • the fitting With a view to avoiding such difficulties in applying the fittings, it has been further proposed to subdivide the fitting into a base body and an extensible part, the base body being cup-shaped in the recess and provided with internal retaining means for the extensible part.
  • the base body preferably of cylindrical or nearcylindrical shape, is insertable in a recess of corresponding diameter at or near the top end of the door leaf in which it is secured by the interlocking action of serrations provided on its cylindrical perimeter.
  • the extensible part consisting of a head member sliding in the guide rail, an adjoining neck part and, adjoining to this, a shaft, is guided with said shaft in a hole of the base body in which it can be moved both up and down as well as tumed.
  • the shaft is fitted with a grip element by means of which the extensible part can be moved and brought into two extreme positions and an intermediate position in the base body.
  • base body is shaped as a circle with a segment cut off
  • this object is achieved in a fitting of the type initially referred to by forming the holder with two jaws connected to the hanger and providing radially spreading means, such as an eccentric cam, to lock the holder positively in the recess.
  • An advantageous version of the fitting according to the invention has the holder designed with an annular shape with the spreading means, e.g., an eccentric cam, located in its center.
  • This design of the holder offers an advantage in that the recess to be provided for it in the door leaf can be produced with a simple tool, e.g., an auger bit or a router.
  • the holder is made flat at the level of the top edge of the sliding door and has the jaws connected to the hanger member at or near this flat portion or segment line.
  • This flat portion or rather segment face enables the holder to be applied direct at the edge of the sliding door top so that the fitting can be placed with relative convenience in a concealed location.
  • this arrangement offers the advantage that, apart from the aforementioned recess to accommodate the holder, the door leaf need have no further recesses which also considerably simplifies the cutting of the recess.
  • both the jaws and the eccentric cam are provided with elements of a twist lock arranged so that the elements on the jaws are connectable to those of the eccentric cam.
  • the fitting With a view to making the fitting as a simple moulding, preferably of a plastic material, such as nylon, polyamide etc., its elements, i.e., the hanger and the jaws, form an integral unit, so that only the eccentric cam has to be made separately and pushed between the jaws.
  • the eccentric cam is also a plastic moulding.
  • the spreading element say an eccentric cam
  • the spreading element can be shaped as a socket with a recess to receive a wrench key. With the tool inserted in the socketrecess, the spreading element can be very easily turned into a locked or unlocked position by rotating the tool clockwise or anti-clockwise.
  • the length of the slider equal to the length of the segment line or flat top.
  • the length of the slider can be further increased by either increasing the diameter of the holder or by deepening the imaginary segment removed, i.e., shifting the segment line towards the center of the circle inscribing the holder.
  • the accompanying drawing shows a typical embodiment of the invention as applied to the suspension of sliding doors from a guide rail using an eccentric cam for spreading the jaws.
  • the drawing includes the following schematic representations:
  • FIG. 1 is a front view of a fitting as installed
  • FIG. 2 is an end view of the fitting shown in FIG. 1,
  • FIG. 3 is a section through the plane I-I in FIG. I, excluding the eccentric cam and the door leaf,
  • FIG. 4 is a top view of the fitting shown in FIG. I,
  • FIG. 5 is a rear view of the fitting shown in FIG. 1,
  • FIG. 8 is a rear view of the eccentric cam shown in FIG. I, 2, 4 and 5,
  • FIG. 9 is a side view of the eccentric cam shown in FIG. 1, 2, 4, 5 and 8,,and
  • FIG. 10 is a section through the eccentric cam in the 'plane II-II in FIG. 9.
  • the fitting according to the invention is essentially formed by a hanger I and a holder 2 with an eccentric cam 3, of which the hanger is insertable into a guide rail 4 and the holder registers in a recess 5 of a sliding door leaf 6.
  • this may take the form of a slider, as in the case of the embodiment described and illustrated, or a roller type runner, and the holder 2 may be of cylindrical or near cylindrical shape, as described in the specification, or may have any other basic shape.
  • the holder 2 has two jaws 7 which can be spread radially to lock it in the recess 5 of the sliding door leaf 6, preferably by a sufficiently high contact pressureto transmit the load, an eccentric cam 3 arranged between the jaws 7 being tumed'to produce thelockedand unlocked positions.
  • the holder 2 is provided with an elliptical or cylindrical opening 8 at its center, i.e., between its jaws 7, into which the eccentric cam 3 is insertable and rotatable in either direction for the purpose of locking and unlocking the holder.
  • the jaws 7, which preferably are formed with a convex surface, are firmly connected to the slider of the hanger 1, preferably by means of a web 9.
  • the other, unconnected, ends of the jaws 7 have a gap 10 between them which extends across the hole 8 and a further gap 11 between the webs 9 to the slider 1.
  • the eccentric cam 3 has hookshaped projections 12 on its surface which snap onto raised faces 13 provided on the jaws as the eccentric cam is turned; In the embodiment illustrated, the eccentric cam 3 has only the projections 12 which serve to lock the jaws 7 outside the recess 5, i.e., during shipment and handling. For the purpose of locking the jaws 7 in their spread position, the embodiment illustrated provides for the eccentric cam 3 to be turned beyond a dead center into a position where unintentional disengagement is not possible.
  • the eccentric cam 3 is designed in this example as a socket formed with a multiface recess 14 to receive a wrench key by means of which the eccentric cam can be turned into the aforementioned positions.
  • the cylindrical shape of the fitting is flattened at the top door edge, i.e., its cylindrical-shape is reduced by a circular segment at the top, i.e., to the segment line 15.
  • the reduction of the depth of the fitting by a segment is proportioned so that there is sufficient bearing area left at the jaws 7 to engage the supporting areas of the recess 5.
  • the proportions of the segment line and the slider 1 can be looked upon as being at an optimum when the length of the slider is equal to the length of the segment line. This permits a good bearing area to be obtained of the slider 1 on the guide rail 4 so that the unit pressure acting on the guide rail is a function of the length of the slider. Since, in this fashion, the unit pressure remains within acceptable limits in spite of relatively heavy door leaves 6, movement of the door leaves is possible without any great effort.
  • the door leaf 6 is carried on the convex surfaces of the jaws 7 bearing against the recess 5 in the door leaf.
  • the door leaf 6 rests on these convex surfaces and is positively connected with the holder 2 by a sufficiently high contact pressure to transmit the load produced by spreading the jaws 7 with the aid of the eccentric cam 3.
  • Installation of the fitting in the sliding door leaf 6 is effected in a manner that the fitting, which comes .with the jaws 7 retracted, is slid with its slider into the hollow guide rail 4 to be then placed in the recess 5 provided previously in the sliding door leaf.
  • the jaws 7 of the fitting are relaxed and may be locked in this position by the projections 12 onthe eccentric cam 3 engaging raised faces 13 on the jaws.
  • a wrench key is inserted into the socket of the eccentric cam 3 and this is turned by rotating the tool.
  • Turning of the eccentric cam 3 causes its eccentric surface 16 to press against the inside of the jaws 7 so that the jaws in turn are spread radially outwards. Spreading of the jaws 7 is continued until their convex surfaces are practically in full contact with the surfaces of the recess 5 in the door leaf 6.
  • the jaws 7 are again locked by the eccentric cam 3 having been moved beyond a dead center or detents 17 which prevents it from returning into the unlocked position without any renewed effort, i.e., renewed insertion and turning of the tool.
  • the contact pressure produced in this manner between the holder 2 and the door leaf 6 provides a positive connection between the holder and the door so that their alignment is maintained.
  • the segment line 15 of the circle coincides with the top edge of the door leaf so that the flat top of the holder is preferably flush with the top edge of the door.
  • the jaws 7 rely for the hinge effect entirely on the elastic properties of the material, the deflection on spreading the jaws being accommodated by the webs 9 only.
  • the jaws are returned into their initial position by the restoring force in the webs 9 so as to permit removal of the fitting from the door leaf 6.
  • the fitting is completely sunk into a recess 5 in the sliding door leaf 6 so that its side surface is flush with the door surface. It is obviously possible to conceal the holder 2 by means of some cover and, for this purpose, the socket of the eccentric cam may be provided with a detent to hold such a cover in position.
  • the jaws 7 may be provided on their convex surfaces with a conical bead, such as a segment tooth 18 or a similar projection which is pressed into the recess and maintains the holder perpendicular to its base surface.
  • the element used for spreading the jaws 7, which in the embodiment illustrated is an eccentric cam 3, may be designed as a screw or similar element having eccentric surfaces.
  • the essential feature of the element used for this purpose is that it will radially spread the jaws 7 and maintain them in the spread position.
  • a fitting especially for detachably suspending a sliding door from a guide rail
  • a hanger guided in a guide rail and a holder sunk into a recess at the top end of the sliding door and connectable to the sliding door whereby the weight of the sliding door is carried via the holder and the hanger from the guide rail
  • said holder consisting of two jaws connected to the hanger and an eccentric cam element causing the jaws to be spread radially so that contact pressure secures the holder positively in the recess relative to the sliding door.
  • a fitting especially for releasable hanging of a sliding door on a guide rail comprising: a hanger body having a head portion embodied as a guide means connectable to the guide rail and a base portion embodied as a holding means connectable to the sliding door, both the sliding door and guide rail having recess means respectively formed therewith and into which said head portion and said base portion respectively are insertably connectable into mating relationship, said holding means including two radially spreadable jaws yieldably joined onto said head portion, said jaws being joined to each other only by way of said head portion and at location remote from said head portion being capable of being spread apart, an eccentric cam means insertable between said jaws to be radially 8 spread apart, and projecting means between said jaws to arrest said jaws in at least either of two locking positions.
  • a fitting according to claim 13 in which said base portion with exception of a circular segment has a predominantly circular form, said head portion being joined to the circular segment which connects with said jaws.
  • a fitting according to claim 16 in which there are webs provided by said jaws formed with said base portion at the holding means on said head portion, said webs alone forming connection to said head portion.
  • a fitting according to claim 13 including asleeve means formed into said eccentric cam means radially to spread said jaws, said sleeve means providing multiface surfaces serving as a movable tool to effect spreading of said jaws.
