Definitions

  • the invention relates to a lounger comprising
  • the lounger according to this Offenlegungsschrift employs meshing toothed segments that are connected to the first and the second part of the lounger and that are mutually locked in a first position and that are completely disengaged from each other in a second position so that the one part can be readjusted in relation to the other and subsequently locked again.
  • Locking and unlocking of the toothed segments is effected by operating a handle which co-operates with an eccentric cam. With this lounger the toothed segments come completely clear of each other in the second position, whereupon the backrest, for instance, can be readjusted in relation to the seat without any hindrance.
  • the object of the invention is to provide a lounger as described in the opening lines that overcomes the disadvantages mentioned.
  • first and second toothed segments are resiliently urged into engagement with each other, by an spring member and that in the second position of the cam, the two toothed segments can be disengaged from each other against the force of the spring member by rotating the one part with respect to the other parts.
  • the toothed segments do not entirely disengage from one another but some force must be exerted by, for instance, pushing one's back against the backrest so as to tilt the backrest or by pulling the backrest with one or both hands to place it in upright position.
  • Readjustment is now effected in a safe manner and can take place from the lying or seated position.
  • the teeth of the toothed segments are shaped in such a way as to ensure that, when the cam is in the second position and the one part is rotated with respect to the other part, the second toothed segment is pushed away from the first toothed segment against the force of the spring member.
  • the one part is readjusted relative to the other the teeth of the second toothed segment move jerkily, as it were, over those of the first toothed segment.
  • the backrest cannot of its own accord fold down to the fully reclined position since, as mentioned earlier, some force needs to be exerted for readjustment.
  • the embodiment according to the invention affords a safe manner of changing the position of the lounger.
  • the angle of inclination of the tooth flanks to the line connecting the tips of the teeth lies between 30 and 85 degrees.
  • the tips of the teeth are radiused so as to further facilitate the teeth of the toothed segments to clack past one another when the position of the lounger is changed.
  • the cam for locking and unlocking the toothed segments is eccentrically linked to the second toothed segment.
  • the lounger is provided with a cam on both sides, both cams being fitted with operating hand grips.
  • the cams at both sides of the lounger are connected to each other by means of a through-going shaft so that the position can be changed from either side.
  • the first toothed segment is integral with the first or the second part of the lounger.
  • the lounger is manufactured in a plastics material.
  • the lounger 1 shown in fig. 1 comprises a seat 2 to which are hinged a backrest 3 and a leg rest 4 via hinges 5 and 6, respectively.
  • the lounger is further provided with folding supports 7, 8 and 9 and hinged arm rest parts 10 and 11, which are also hinged to the back rest 3 and the seat 2, respectively.
  • the adjusting mechanism is located within the area indicated by the dotted line I in fig. 1. In this case, an adjusting mechanism is fitted on both sides of the lounger, as will appear from the following.
  • the adjusting mechanism is substantially accommodated in U-shaped reinforcing sections along the sides of the seat 2; the reinforcing sections are open on the outside.
  • Fig. 2 shows the rear elevation of the lounger.
  • the parts have the same reference numbers as those in fig. 1 except that they are accentuated.
  • Fig. 3 the side elevation along line II-II in fig. 2, is a schematic representation to a larger scale of the construction of the adjusting mechanism.
  • Toothed segment 13 forms part of an element 14, which can rotate around a pin 15, which is connected as a fixed point to the seat 2, which is schematically represented by line III.
  • Element 14 ends in a resilient ear 16 which at its extremity is arrested by stop pin 17 connected to the seat 2.
  • the springing ear 16 is integral with the element 14.
  • the element 14 is further provided with a recess 18 with an inner wall 19. Within the recess is located a rotatable cam 20, which is eccentrically placed on a shaft 21 connected to the seat 2.
  • Handgrips 27 and 27' may be fitted onto the cams 20 (see figures 1 and 2).
  • Backrest 3 is readjusted as follows. It is first pointed out that the readjusting mechanism is designed so that, when the element 14 with the springing ear 16 is in the central position, toothed segment 13 is in full mesh with toothed segment 12 as shown in fig. 3.
  • the cam 20, in the position as drawn acts in concert with the inner wall 19 of recess 18 so that the longer eccentric side 22 of the cam with its free end 23 is firmly pushed against the element 14 so that the toothed segments are meshed and locked. In this position it is not possible to readjust the backrest 3 around hinge 5 in relation to the seat 2.
  • the angle of inclination of the tooth flanks to the line connecting the tips of the teeth lies between 30 and 85 degrees.
  • the tooth flanks on one side have the same angle of inclination as those on the other side.
  • Cam 20 is eccentrically coupled to the toothed segment 13.
  • a cam may be provided on both sides of the lounger.
  • Operating handgrips may be fitted to the cams.
  • the cams may be connected to one another by means of a through-going shaft so that the lounger may be readjusted from either side.
  • the toothed segment 12 may be integral with the backrest 3.
  • the lounger is manufactured in plastic and is, thus, especially suited as a garden lounger.
