Definitions

  • the invention relates to a joint, in particular for couches such as garden or camping chairs with a central part and a headboard.
  • Lying hinges are used to articulate a headboard to a couch frame and to hingedly support a footboard serving as a support to the couch frame as disclosed in FR 1 225 971 A, US 4 354 710 A, US 3 918 822 A or CH 358 289 A are known.
  • the headboard should be adjustable in several angular positions relative to the rest of the couch surface. In known couch joints, it is provided to first unfold the foot before a pivoting of the head part relative to the rest of the bed is done, however, this function is not always safe, or accidentally wrong handling the headboard folded back and then the foot in his Support position are brought.
  • the present invention has for its object to provide a joint, especially for couches, which is simple in construction and yet safe to handle.
  • the joint of the invention is characterized u. a. characterized in that it consists of an extremely small number of easily manufacturable mold elements that are easy to install. Depending on the required force acting as torque on the slide, the teeth can be dimensioned accordingly.
  • the slider comprises a cranked portion so that the slider extends laterally adjacent to a rivet serving as an axis of rotation of the mutually pivotable form element pairs of the central portion and head portion.
  • a plurality of projections are arranged in a first group on the outer shells, which is diametrically opposed to an equal number of projections of a second group. Intermediate spaces with the same contact surfaces and / or sliding surfaces for the slide or its elements are formed between the projections.
  • These groups with different shapes of projections, and consequently also gaps, allow the one group to serve both as a detent and in one direction to enable detent advancement, while the second group projections are merely for detention and thus for power transmission.
  • the projections of the first group each have an inclined surface on which slides along a pivoting of the head portion in one direction, a front edge of the slider.
  • the slider In order to lock the slide as needed so that it is locked with respect to the longitudinal part with respect to the longitudinal direction relative to its longitudinal direction, measures can be provided by the slider is moved, for example, at its spring adjacent teeth transverse to the longitudinal direction of the slider and behind a Paragraph of the relevant opening engages in the inner shell. Additionally or alternatively, it is possible that the slider has an additional tooth on a side edge, which engages in a guide slot in one of the inner shells, wherein the guide slot has a portion on which a shoulder is formed. Such an embodiment of the additional tooth is to be provided in particular in such arrangements in which only the front end of the slider is provided with locking members.
  • additional projections are formed on the outer shells, it being appropriate that one of these additional projections of the first group of projections and the additional additional projection is associated with the other group of projections.
  • the spring is arranged in a simple manner in a nozzle formed from the form elements, wherein the spring is supported against an integrally formed with the form elements spring stop.
  • the joint according to the invention is provided with a foot part which is pivotally mounted on the central part.
  • the foot part preferably consists of a hollow profile having at its end two parallel wall parts with congruent bores for receiving a serving as a pivot axis component, said wall parts are used to form a hinge with the pair of form elements, which forms the middle part.
  • a first outer shell of a pair of shaped elements is provided with a formation which cooperates with a hinge forming the first wall part.
  • This formation is preferably substantially circular segment-shaped and on the first wall part a concave sliding contour is formed whose curvature is adapted to the radius of the circular segment.
  • a second outer shell of a pair of mold elements has an integrally formed projection which extends in the axial and radial directions and the second wall portion of the Foot has such a contour that, depending on the pivot angle of the foot part of the projection cooperates with the wall part or is released.
  • this wall part it may also be possible that the foot part must first be swung out by a certain angle and the rest of the swinging forcibly occurs simultaneously with the unfolding of the headboard from the middle part.
  • the middle part of the inner shells and the head part, the outer shells are assigned.
  • the outer shells are part of the middle part.
  • the inner cavity should be closed with the moving parts therein against the outside. It is therefore expedient that the inner shells each have a mutually directed edge, so that there is an outwardly closed contour.
  • a bed hinge 1 is shown in perspective in the position of use.
  • This bed hinge 1 comprises a central part 2, a head part 3 and a foot part 4, wherein in this context the term "foot part” means the support of a couch.
  • the middle part 2 consists of two mold elements 5, 5 ', which are sheet metal parts in the embodiment. These sheet-metal shaped parts 5, 5 'comprise inner shells 7, 7' and form a nozzle 5 * in an oblong region.
  • the head part 3 consists of two mold elements 6, 6 ', also embodied here as shaped sheet metal parts, each comprising an outer shell 8, wherein the elongated portions of the sheet metal shaped parts 6, 6' form a nozzle 6 *.
  • the outer shell 8 is provided with a plurality of indentations, which form inwardly directed projections 9, which will be discussed in more detail to the other figures.
  • the inner shells 7, 7 * and the outer shell 8 are arranged concentrically to each other and through a central bore in each of these shells, a rivet 11 extends, which represents the axis of rotation for the joint formed from the central part 2 and the head part 3.
  • the foot part 4 comprises at its upper end wall parts, of which in Fig. 1, only a wall part 13 is visible, which is connected by means of a rivet 12 hingedly connected to the formed from the sheet metal parts 5, 5 'middle part 2.

  • the spring 23 is effective and close to it Area are provided two lateral teeth, which serve as locking members 28.
  • the slider 25 is guided with the locking members 26 in the openings 30, 30 'and with the locking members 28 in the openings 31, 31'. It can be seen on the inner shell 7 that the opening 31 has a section 31 "on which a shoulder 31 * is formed, behind which the locking members 28 can be hooked in. It may be advantageous, in addition to this hookability, to have a side edge of the slider 25 To form additional tooth 29, which 'engages in a guide slot 32 of the inner shell 7 and in a certain position in a section 32' of the guide slot 32 behind a paragraph 32 * reaches a position in which the slider 25 is not displaced.
  • the two inner shells 7, 7 ' have recesses 18 which are of circular design and are located at a certain distance from an edge 17, 17', this distance forming an annular surface 19. With the open edges of the edges 17, 17 'are the two sheet metal parts 5, 5' against each other and thus form the closed cavity between the inner shells 7, 7 '.
  • the outer shells 8, 8' of the sheet metal parts 6, 6 ' are arranged, which have inwardly directed projections 9, 10, 38, 39, which cooperate with the locking members 26 and 28. That the locking members 26, 28 engage in intermediate spaces between the projections 9 and 10, in particular from Fig. 5 clearly.
  • a plurality of projections 9 and a projection 38 and a projection 46 are provided in a first group of projections, wherein a diametrically opposite second group projections 10 and a projection 39 comprises.
  • the shape of the projections of the respective Gurppe is chosen so that there are gaps between them, the same locking surfaces and sliding surfaces - with the exception of the projection 38 - form.
  • the function of the projections 38 and 39 will be explained later to Fig. 6 and 7.
  • the outer shells 8, 8 ' have at their periphery a circumferential flange 33, which covers the annular surface 19 of the inner shells 7, 7' and thus prevents the ingress of dirt into the recess 18.
  • the outer shells have centric bores 20, 20 'and the inner shells 7, 7' have centric bores 21, 21 ', through which the rivet 11 extends, which the pivot axis for the mutually pivotable sheet-metal shaped parts of the central part and the head part forms.
  • the sheet metal parts 5, 5 'holes 22, 22' are provided, which are congruent.
  • the foot 4 has at its upper end the already mentioned wall part 13 and a parallel thereto extending wall part 13 ', wherein the two wall parts 13, 13' with congruent bores 16, 16 'are provided.
  • the foot part 4 engages with its wall parts 13, 13 ', the central part 2 and through the holes 16, 16', 22, 22 ', the rivet 12, which thus forms the axis of rotation for the hinge-like joint between the middle part 2 and the foot part 4 extends ,
  • the embodiment of the expression 14 and the sliding contour 15 has already been described with reference to FIG. 1.
  • a projection 45 is formed, which protrudes radially and axially outwards and whose function will be explained below to Fig. 3.
  • support edges 44 are formed, which come to lie in the position of use of the couch joint for resting against the outer periphery of the sheet metal parts 5, 5 '.
  • Fig. 3 shows a side view of the couch joint 1 in the folded state.
  • the sockets 5 * and 6 * are parallel to one another, ie the head part 3 is pivoted onto the middle part 2.
  • the foot part 4 is also pivoted to the central part 2 and also extends substantially parallel to the central part 2.
  • the integrally formed on the outer shell 8 'projection 45 is located at a blocking edge 41 of the wall portion 13', so that it prevents the head part 3 is folded up can be, as long as the foot part 4 is not pivoted about the rivet 12 by a predetermined angle. This ensures an order for handling, ie the foot part 4 must first be swung out before a pivoting of the head part 3 is possible.
  • a transition 42 is provided to a driving portion 43, so that the foot part 4 must be at least over the transition portion 42 also moved past the projection 45 to a movement of the head part 3 relative to the Center part 2 to allow. If the foot part 4 is not yet fully unfolded, the remaining pivoting of the foot part 4 is generated by the pivoting of the head part 3 relative to the middle part 2 via the introduction of force of the projection 45 on the driving portion 43.
  • the reference numerals in Fig. 3 Match for the same parts with those of Figs. 1 and 2.
  • FIG. 4 shows a side view of the bed hinge 1 with the foot part 4 completely unfolded, but with the head part 3 still folded.
  • the position of the slide 25 and the spring 23 acting thereon are shown by dashed lines in FIG.
  • Fig. 5 shows a section along the line V-V in Fig. 4. From this illustration it can be seen that the edges 17, 17 'of the inner shells 7, 7' abut each other and thus form a closed against the outside cavity within the inner shells. On the outer sides, the inner shells 7, 7 'covered by the outer shells 8, 8', wherein the flange 33 rests on the annular surface 19 and thus prevents the ingress of dirt.
  • the slider 25 is in its against the force of the spring 23 displaced end position, so that the locking members 26 and 28 are disengaged from the spaces between the projections 9 and 10. It is apparent from Fig. 5, however, that the locking members 26 and 28 laterally project so far into the cavity formed by the outer shells 8, 8 ', that upon engagement between the projections 9 and 10, a locking against pivoting of the head part 3 relative to the central part 2 is reached.
  • FIGS. 6 to 8 show the inside of the middle part 2 and head part 3 in different functional positions of the joint. Since in the folded state shown in FIG. 4, the slider 25 is located in the position in which this is moved against the spring 23 and held immovably, is when unfolding the joint, ie pivoting of the head part 3 relative to the middle part 2 - in the example of FIG. 6 in the clockwise direction - causes no blockage, since the projections 9 and 10 are outside the path of movement of the locking members 26, 28.
  • the projection 39 comes into abutment against the slide 25, namely on the additional tooth 29, and thus lifts the slide 25 or the teeth 28 and 29 behind the shoulders 31 *, 32 * out in a position in which the locking members or the additional tooth are no longer held and thus the slider 25 is longitudinally displaceable.
  • a long flank 40 is provided on the projection 38, by which the slider 25 is moved so far against the spring 23, that the locking members 28 and the additional tooth 29 in the sections 31 'and 32' of the guide slots, whereby the region 34 of the slider 25 are pressed by the spring behind the shoulders 31 *, 32 *, so that the slider is no longer displaceable in its longitudinal direction in this position.
  • Fig. 9 shows an alternative embodiment of the central part 2 and the head part 3 such that the inner shells 7 part of the head part and the outer shells 8 are part of the middle part. This makes it necessary that the spring 23 is disposed in the socket 6 * of the head part. Otherwise, however, the arrangement is the same.
