Definitions

  • the invention relates to a hinge joint of the type mentioned in the preamble of claim 1.
  • Such hinge joints are used, for example, for pivotably fastening the cover of a conventional music cassette housing to this cassette housing.
  • the cover has two mutually parallel tabs with coaxial pins facing each other.
  • the tabs are elastic in the direction of the pin axes.
  • the bearing recesses for receiving the pins are formed on the outer sides of two side walls of the cassette housing.
  • To mount the cover the tabs are elastically bent apart so that the pins are placed on the side walls serving as guide walls.
  • the cover is moved transversely to the direction of the pin axis until the pins are aligned with the associated bearing recesses and snap into them because of the spring tension of the tabs.
  • a disadvantage of these known hinge joints is that in the case of the individual joint, the pin is not aligned with the axis of the bearing recess during assembly, so that the pin can be tilted in any direction relative to the axis of the bearing recess, as a result of which the pin engages precisely in the Bearing recess is not ensured. Alignment of the pin to the bearing recess takes place only by an exact guidance of the other pin, which cooperates with the pin in pairs. For this reason, a hinge joint construction of the known type cannot be used as a single hinge.
  • a hinge joint of the type mentioned in the preamble of claim 1 is already known, but which is designed as a double-hinge double hinge.
  • the first component is not supported by a separate guide surface formed thereon, which bears against a separate guide surface provided on the second component; rather, each individual joint forms the support for the other individual joint.
  • the guide rail has such a width that it lies practically over the entire length of the pin.
  • the guide wall for the pin is designed as an inclined, elastically evasive wall.
  • the known double hinge is complicated in construction and, in particular, cannot be installed in a space-saving manner in an inner corner of a box-like component, since it has essentially twice the width in the direction of the pin axis compared to a single-pin hinge. Since the guide surfaces form a largely tilting guide for the pin during assembly, the guide rail can have a smaller thickness than the pin length, so that it only forms a side guide, with which tilting or stiffness can be reliably avoided.
  • the guide rail guiding the pin at a distance from the pin end forces the pin to assume a position in which the pin axis lies in a plane containing the axis of the bearing recess. Any inclination in this plane is automatically corrected in that the pin is precisely aligned in the final phase of the assembly movement on the one hand by the bearing recess and on the other hand by the stop edge.
  • the guide rail can be designed as a closed rail into which the pin is inserted in the axial direction and then displaced transversely to its axial direction.
  • the guide rail is preferably open at its front end in the direction of displacement, so that the pin can be inserted into this rail transversely to the axial direction and can be guided out of this rail.
  • the guide rail is preferably semicircular with an axis concentric with the axis of the bearing recess (hinge axis) and with an inner diameter corresponding to the diameter of the pin in the area guided by the guide rail.
  • the rear end serves the Guide rail as a bearing shell for the pin, which surrounds this on its half circumference and supports against forces acting in the corresponding direction on the pin.
  • the bearing recess can then essentially have the shape of a bearing half-shell which is open in the direction of assembly when viewed in the direction of the hinge axis; the bearing shell formed by the guide rail, which supports in the mounting direction, and the bearing shell formed by the bearing recess, which supports the pin in the opposite direction, complement one another to form a bearing surrounding the pin on all sides.
  • the guide rail is formed by a tab which is essentially parallel to the guide wall of the second component and has an approximately U-shaped recess which opens into a free tab edge with its open end.
  • At least one guide surface arranged essentially transversely to the pin axis is connected to the first component, which lies against a guide surface connected to the second component essentially transversely to the hinge axis when the pin is moved.
  • These guide surfaces are preferably designed so that they secure the pin against a withdrawal movement out of the bearing recess; however, it is also possible to fix the pin in both axial directions, as will be described in more detail below.
  • the guide wall of the second component is formed by a tab which is transverse to the hinge axis and elastic in the direction of the hinge axis and which performs the evasive and snap movement.
  • a ramp arranged in the assembly direction in front of the bearing recess and rising in the assembly direction towards the guide rail is provided on the guide wall of the second component.
  • a bearing block in which the bearing recess is formed, is arranged on the guide wall of the second component; the pedestal has a ramp that slopes from its top against the direction of installation to approximately the guide wall.
  • the bearing recess is approximately U-shaped with a semicircular part concentric to the hinge axis with an inner diameter corresponding to the outer diameter of the pin end, and with a straight-line part adjoining it in the mounting direction and opening into a side surface of the bearing block.
  • the pin with its root end facing away from the free pin end is fastened vertically on a holding bracket, that is to say it is clamped on one side.
  • the retaining tab is preferably on all sides over the circumference of the pin root, the top and bottom of the retaining tab can serve in cooperation with counter surfaces formed on the second component as guide surfaces for axially fixing the pin.
  • one of these counter surfaces is formed by the guide rail on which the retaining tab rests.
  • a guide surface which is transverse to the hinge axis and which fixes the pin in the axial opposite direction is arranged.
  • the pin is essentially conical in shape with a decreasing diameter from the pin root to the pin end, and the pin end is formed by a cylindrical section with a smaller diameter than the pin section adjoining this cylindrical section.
  • the bearing recess has at least one depth corresponding to the length of the cylindrical section, so that in the event that the bearing recess does not completely penetrate the guide wall, the end face of the pin end does not rest on the bottom of the bearing recess. Static indeterminacy of the axial fixing of the pin can thereby be avoided.
  • the tab forming the guide rail is fastened to the walls of the second component perpendicular to the plane of the tab, with a side edge running parallel to the mounting direction and a trailing edge running transversely to the mounting direction, so that this tab is extremely stable in the direction of the hinge axis.
  • the tab forming the guide wall is, according to the invention, only fastened with a trailing edge running transversely to the mounting direction on a wall of the second component which is perpendicular to the plane of the tab, so that this guide wall can be elastic in the direction of the hinge axis, whereby the elastic evasive and snap movement is clear is assigned to this tab.
  • the hinge joint shown in Fig. 1 is used for the pivotable connection of a first component 2 with a second component 4.
  • a pin 8 is fastened on one side to a retaining tab 6, so that it is attached to it Pin end 10 protrudes freely.
  • the pin 8 is substantially conical with a decreasing diameter from the pin root to the pin end 10.
  • the pin end is formed by a cylindrical section 12, the diameter of which is smaller than the smallest cone diameter of the pin 8 adjoining this section 12.
  • the second component 4 for example a housing, has a plurality of walls delimiting the interior of the housing; In Fig. 1, two mutually perpendicular side walls 14, 16 and a top wall 18 are shown, which form a housing corner.
  • a guide wall 20 is provided with a bearing recess 22 for receiving the pin end 10.
  • the central axis of the bearing recess 22 forms the hinge axis 24.
  • the first component 2 and the pin 8 attached to it become corresponding in a mounting direction lying transverse to the pin axis 26 the arrow 28 shifted until it has reached a locking position aligned with the bearing recess 22 and engages in the bearing recess.
  • a guide rail 30 is arranged in the direction of the hinge axis 24 at a distance from the guide wall 20. It is aligned in the mounting direction 28 and closed at its rear end in the mounting direction so that it forms a stop edge 32. This stop edge 32 defines the locking position of the pin 8, in which the hinge axis 24 and the pin axis 26 coincide. At its front end in the direction of displacement 28, the guide rail 30 is open, so that the pin 8 can be inserted into the guide rail 30 transversely to the pin axis 26.
  • the stop edge 32 is semicircular with an inside diameter corresponding to the outside diameter of the pin 8 in its root area and an axis concentric with the hinge axis 24. In this way, the stop edge 32 forms a bearing shell encompassing and supporting the pin root on half of its circumference.
  • the bearing recess 22 has the shape of a bearing half-shell which is open in the mounting direction 28 and which likewise encompasses and supports the pin end 10 on half of its circumference.
  • the bearing shell formed by the stop edge 32 and the bearing shell formed by the bearing recess 22 complement one another to form a closed bearing, so that the pin 8 is fixed in all radial directions after it has snapped into the bearing recess 22.
  • the guide rail 30 is formed by a tab 34 parallel to the guide wall 20, into which a U-shaped recess 38, with its open end opening into the free tab edge 36, has been made.
  • the tab 34 is fastened to the walls 14 and 16 at least with its rear edge 40 running transversely to the mounting direction 28, but preferably also with its side edge 42 running in the mounting direction 28, so that it is extremely rigid in the direction of the hinge axis 24.
  • the guide wall 20 is also designed as a tab 44, which is preferably only attached to the wall 14 with its rear edge 46, so that it can deflect elastically in the direction of the hinge axis.
  • a bearing block 48 is arranged on the guide wall 20, in which the bearing recess 22 is formed.
  • the bearing block 48 has a ramp 50 which slopes from its top against the mounting direction 28 to approximately the top of the guide wall 20.
  • the bearing recess 22 passes through only part of the height of the support bracket 48.
  • the depth of the bearing recess 22 is at least the same, preferably somewhat greater than the length of the cylindrical section 12 of the pin 8.
  • the underside of the top wall 18 facing the tab 34 forms a guide surface which cooperates with the hinge joint.
  • the distance a between the tab 34 and the top wall 18 corresponds approximately to the thickness b of the retaining tab 6.
  • the pin 8 When the pin 8 is displaced in the assembly direction, the pin end 10 runs against the ramp 50 and thereby deflects the tab 44 downward. After reaching the locking position, the pin end 10 snaps into the bearing recess 22 and the tab 44 snaps back into its starting position. Due to the joint action of the bearing recess 22 on the one hand and the bearing shell-like stop edge 32 on the other hand, the pin 8 is also fixed on all sides in the radial direction.
  • the dimensions of the cylindrical portion 12 of the pin 8 on the one hand and the bearing block 48 and the bearing recess 22 on the other hand are coordinated so that the pin 8 neither with its end face on the bottom of the bearing recess 22 nor with the paragraph 52 between the section 12 and the rest Pin part rests on the top of the bearing block 48, so that any static uncertainty axial storage is avoided.
  • a possible resting of the shoulder 52 on the top of the bearing block 48 or the end face of the pin 8 on the bottom of the bearing recess 22 has no significant effect, since the tab 44 can move downwards.
  • the pin 8 can in principle also have a cylindrical shape; however, the conical configuration can have advantages for the bending strength of the pin, since the increasing bending forces corresponding to the pin root correspond to an increasing pin cross-section.
  • the cylindrical configuration of section 12 also makes it possible to design the bearing recess 22 in its semicircular part to be cylindrical, which has advantages in terms of production technology.
  • a slot 54 is formed in the wall 14, the height and width of which corresponds at least to the height and width of the bearing block 48.
  • a shaped slide 56 of the type shown in FIG 2 are introduced, which, in a known manner, enables the design of the profile of the bearing block 48 which is open towards the wall 14.
  • FIG. 3 shows a hinge joint essentially corresponding to the exemplary embodiment according to FIG. 1 in a different viewing direction; Identical parts are identified by the same reference numerals, increased by one hundred. It can be seen that the side edges of the tab 144 forming the guide wall, in particular the side edge 117 facing the wall 116, run obliquely and are not connected to the wall 116. In this way, an elastic evasive movement in the direction of the hinge axis 124 is not hindered when the hinge joint is assembled.
  • a stop lug 107 is formed which, when the holding bracket 106 is pivoted completely in the direction of the part 109 with the hinge joint mounted, bears against the outer edge 111 of the bracket 134 forming the guide rail and thus a pivoting end position of the first component 102 defined.
  • the tab 134 is reinforced in the area in which the stop lug 107 comes to rest by a reinforcing web 113, which prevents the tab 134 from being lifted by the stop lug 107 and thus prevents the stop from becoming ineffective.
  • a coil spring 115 is wound around the pin 108, one end 117 of which is supported on the first component 102 and the second end 119 of which rests against the wall 116 when the hinge joint is mounted.
  • This helical spring 115 generates a force acting on the first component 102 in the direction of the arrow 109; if the first component 102 is, for example, the cover of a housing, the coil spring 115 preferably acts in a direction supporting the cover weight.
  • the front tab edge 136 of the tab 134 is provided with a rounding 139 which merges into the recess 138 and is intended to facilitate insertion of the pin 108 into the recess 138.
