Definitions

  • a stationary tubular guide member has a upwardly directed open end and a vertically oriented longitudinal axis.
  • a pivot Filedl 3, 1970 pin has an upper portion projecting above the open end for engaging and supporting a swingable element, an intermediate [21] Appl' 79148 portion between the upper portion and the open end, and a lower portion located within the guide member with limited [30] Foreign Application Priority Data freedom of axial displacement therein.
  • a retaining pin prevents the pivot pin from turning with reference to the guide Oct. 17, Germany ..P 19 52 member.
  • a downwardly p p surrounds with its pp r section the intermediate portion of the pin and with its lower [52] US.
  • the present invention relates generally to pivotal supports, and more particularly to pivotal Supports serving as a hinge for use at the bottom of a door or analogous swingable element.
  • Pivotal supports used for such purposes are already known. They are employed when other types of hinges cannot or are not desired to be used, and they cooperate with a socket provided in the downwardly directed bottom edge face of the door or other swingable element, in which an upwardly facing end portion of a pivot pin of the support is received so that the element can pivot about an upright axis defined by the elongation of the pivot pin.
  • these known pivotal supports are adjustable in that their pivot pin can be raised or lowered within certain defined limits.
  • a concomitant object of the invention is to provide such a pivotal support wherein the pivot pin can be raised and lowered reliably and in a most simple manner, even under the most disadvantageous circumstances as concerns the location and accessibility of the support.
  • Still another object of the invention is to provide such a support which is protected in a simple and reliable manner against undersired displacement of the pivot pin out of the position which has once been selected and set.
  • a pivotal support particularly as a hinge for use at the bottom of a door or analogous swingable element
  • a pivotal support which according to one embodiment comprises a stationary tubular guide member having an open end and a longitudinal axis and which is adapted for mounting with its axis vertically oriented and with the open end facing upwardly.
  • a pivot pin is provided having an upper portion projecting upwardly of the open end for engaging and supporting a swingable element, an intermediate portion between the upper portion and the open end, and a lower portion accommodated within the guide member with limited freedom of axial displacement therein.
  • Retaining means retains the pivot 'pin against rotation with reference to the guide member.
  • a downwardly open cap member has an upper section surrounding the intermediate portion of the pin, and a lower section surrounding the guide member. Cooperating screw threads on the intermediate portion and upper section permit rotation of the cap member with reference to the pivot pin with concomitant axial displacement of the latter with reference to the guide member.
  • the pivot pin is prevented from rotating but is capable of performing axial movements in a sense raising or lowering it. Torque transmitted to the pivot pin when the swingable element associated therewith is moved between its various positions, will be directly transmitted to the guide member rather than via the screw-threaded means, whereby undersired displacement of the pivot pin from its once-selected position is avoided even under disadvantageous circumstances.
  • the cap member serving for displacing the pivot'pin axially will always be'maintained in its predetermined position with reference to the bottom of the swingable element and with reference to the elongation of the guide member, that is the cap member will not move upwardly or downwardly with reference to the guide member as does the pivot pin when adjustments are made.
  • the cap member will always be located in one and the same position and always be readily accessible. Because of this the present construction does not require the pivotal support to be laterally offset from the downwardly directed bottom face of the door or other swingable element as is the case in certain known constructions where this is necessary in order to be able to have access to the support for adjusting purposes.
  • the bottom face of the cap member will abut slot the mounting means-for instance the floor, the sill or the like-in which the guide member is mounted stationarily with its axis vertically oriented.
  • the cap member engage the upper end face of the tubular guide member so as to be axially supported thereby.
  • the lower end portion of the guide member which will normally be accommodated in an aperture of the mounting means, such as the floor, the sill or the like, is provided with an axially extending slot through which a pin extends inwardly and outwardly of the circumferential wall of the guide member, with its outward end being anchored in the mounting means while its inward end extends into an axial recess provided in the lower portion of the pivot pin and registering with the slot.
  • the mounting means with a similar slot and to have the outer end portion of the pin or retaining rod member also be located in this similar slot. In any case, this provides for a reliable retention of the pivot pin against rotation with reference to the guide member.
  • the lower end portion of the guide member is of circular outline, it will at the same time provide for a retention of the guide member itself against rotation.
  • the recess provided in the lower end portion of the pivot pin will terminate short of the downwardly directed lower end face of the latter so that an additionalfunction achieved by the retaining pin or retaining rod member will be to prevent undersired separation of the pivot pin from the guide member, for instance when the pivotal support is in storage or is being transported prior to its installation.
  • the manner in which the guide member maybe secured to its mounting means may vary.
  • its lower end portion will have a smaller diameter than its upper portion and be externally threaded, being received in an opening for'this purpose in the mounting means, such as the floor, the door sill or the like.
  • a retaining nut is then threaded onto this lower end portion from the underside of the mounting means whereas the shoulder provided on the guide member to the diameter differential engages the mounting means at the upper side and provides for reliable abutment in a simple manner, with the thus-mounted support being capable of carrying substantial loads.
  • FIG. 1 is a vertical section through a pivotal support according to the present invention, with portions of the associated swinging element and of the mounting means being also shown in vertical but fragmentary section for purposes of orientation;
  • FIG. 2 is a section taken on line IIII of FIG. 1;
  • FIG. 3 is a side-elevational view of the pivotal support shown in FIG. 1, with portions of the associated swinging element and mounting means being shown for purposes of orientation in broken lines.
  • reference numeral 19 identifies part of a mounting means, for instance a floor door sill or the like, whereas upwardly spaced from the mounting means 19 is a swingable element which has been identified in toto with reference character E.
  • This may be a door, a window or the like, but for purposes of the exemplary embodiment illustrated it will be discussed as a door.
  • the present invention is concerned exclusively with the illustrated pivotal support provided at the lower end of the elementor door E, and therefore no attempt has been made to illustrate corresponding pivot means provided at the upper end of the element E, such corresponding pivot means forming no part of the present invention and it being understood that it may be of any conventional type.
  • the novel pivotal support comprises a tubular guide member having an upper open end and a longitudinal axis which is quite obviously vertically oriented.
  • a pivot pin having the portion 11 and the upper portion 12 which in the illustrated embodiment is a discrete portion and consists of synthetic plastic material.
  • the head of the portion 12 also need not be of the illustrated hemispherical configuration.
  • the head of the portion 12 be receivable in a correspondingly configurated recess ofa socket member 14 which is secured to the underside or bottom face of the element E, for instance in the illustrated manner by screws, or in any other suitable way.
  • the element E and the socket member 14 rigid therewith can then turn with reference to the portion 12.
  • the guide member 10 has, as evident in the drawing, a center passage which is of circular cross section and extends from one to the other axial end of the guide member 10, although the axial end which in the operative position shown in the drawing is the lowermost one, could of course also be closed.
  • the upper portion 15 of the guide member is of cylindrical configuration and is followed downwardly by a lower end portion 16 whose cross section is smaller than that of the portion 15 and which is provided with external threads 17.
  • the lower end portion 16 is provided with an elongated slot elongated in axial direction of the guide member 10, and a retaining pin or retaining rod member 20 extends through this slot with its outer end portion projecting into a corresponding slot or groove 21 provided for this purpose in the means 19 whereas its inner end portion projects into a groove 22 provided in the portion 11 of the pivot pin, with this recess 22 being axially oriented with reference to the pivot pin and registering with the slot in the lower end portion 16.
  • the groove 22 is provided in the portion 23 of the pin 11. It is closed in downward direction, that is it terminates short of the bottom end face of the portion 23 for the reasons pointed out earlier.
  • the outer end portion of the pin 20 could be retained in and by the means 19 in another manner, instead of in a groove 21 as illustrated.
  • the portion 23 has slight play in the bore or center passage of the guide member 10.
  • the portion 24 of the pin projects upwardly above the guide member 10 and has a greater thickness or diameter than the portion 23; it is also provided externally with the illustrated screw threads.
  • the downwardly open cap member 13 surrounds with its lower portion the portion 15 of the guide member 10, whereas its upper portion-which as illustrated has a smaller interior cross section than the lower portion-is internally tapped so as to mesh with the screw threads on the portion 24 of the pin 11, as illustrated and as already discussed. It is advantageous, and carried into effect in the illustrated embodiment, that the axial length of the different-diameter portions of the cap member 13 be so selected that the lower end face of the cap member 13 abuts against the mounting means 19 so that the latter supports the cap member 13. It is emphasized again, however, that it is also possible to have the cap member 13 supported by axial engagement with the upper open end face of the tubular guide member 10.
  • At least the lower part of the outer circumferential surface of the cap member 13 is provided with engagement surfaces which define, for instance, a hexagonal profile, to permit ready engaging and turning of the cap member 13 with a suitable wrench or other applicable tool.
  • a pivotal support particularly a hinge for use at the bottom of a door or analogous swingable element, comprising a stationary tubular guide member having an open end and a longitudinal axis and being adapted for mounting with said axis vertically oriented and said open end facing upwardly; a pivot pin, including an upper portion projecting upwardly of said open end for engaging and supporting a swingable element, an intermediate portion between said upper portion and said open end, and a lower portion located within said guide member with limited freedom of axial displacement therein; retaining means retaining said pivot pin against rotation with reference to said guide member; a downwardly open cap member having an upper section surrounding said intermediate portion, and a lower section surrounding said guide member; and cooperating inner threads on said intermediate portion and upper section, rotation of said cap member resulting in axial displacement of said pivot pin with reference to said guide member.
