Definitions
- the invention relates to a folding chair of the type specified in the preamble of claim 1.
- the front leg pair and the rear leg pair form two collapsible strut crosses on both sides of the seat plate and below the backrest bracket.
- the two strut crosses are connected to each other by cross struts, which each extend between the front leg pair or the rear leg pair and on which the seat plate rests, which is rotatably attached to the cross strut of the front leg pair and can be locked with the cross strut of the rear leg pair.
- the two pivots of one or the other strut cross define a transverse axis about which the front leg pair and the rear leg pair can be pivoted relative to one another.
- the two rear legs are rotatably supported at the respective upper end by means of a pin in a lower bearing block on the relevant side arm of the backrest bracket, which is arranged in the region of the free end of this side arm.
- These two pins define a further transverse axis about which the pair of hind legs and the backrest bracket can be pivoted relative to one another.
- the pair of forelegs crossing the pair of hind legs runs in the opposite obliquely inclined manner, the two front legs also each being provided at the upper ends with a pin which is received in a longitudinal slot of the mentioned bearing block on the relevant chair side.
- These two pins define a third transverse axis about which the pair of front legs and the backrest bracket can be pivoted relative to one another, this transverse axis shifting with respect to the backrest bracket, which enables the aforementioned longitudinal slots.
- the invention has for its object to provide a folding chair of the type specified in the preamble of claim 1, which is characterized in particular by greater stability, simpler and less expensive structure, easier to use and a more pleasing appearance.
- the folding chairs each consist of a U-shaped backrest bracket 1, a narrower seat plate 2 with a corresponding U-shaped outline, a pair of front legs 3, a pair of rear legs 4, a first pair of struts 5, a second pair of struts 6, a third pair of struts 7 and a pair of sliding pieces 8 .
- the two upper ends of the front leg pair 3, the two upper ends of the rear leg pair 4 and the two front ends 1 'of the backrest bracket 1 are pivotally connected to one another by means of two joints on one or the other side of the chair about a common transverse axis 10.
- the seat plate 2 is pivotally connected to the front leg pair 3 in the region of its straight front edge about a transverse axis 11.
- the three pairs of struts 5, 6 and 7 are each at one end with the pair of sliding pieces 8 about a common transverse axis 12 and at the other two ends with the backrest bracket 1 in the rear area thereof or with the seat plate 2 between the transverse axis 11, that is the pivot axis of the seat plate 2 on the front leg pair 3, and the pair of sliding pieces 8 in the unfolded state of use according to Fig. 1 or 5 of the folding chairs or with the lower ends of the front leg pair 3 each pivotable about a transverse axis 13 or 14 or 15.
- the two sliding pieces 8 are each slidably arranged on one or the other rear leg 4, the rear leg pair 4 being curved, as can be seen from the drawings, and having a greater length than the front leg pair 3.
- the pair of front legs 3 extend substantially vertically, the pair of rear legs 4 from the transverse axis 10, that is to say the pair of front legs 3, the Rear pair of legs 4 and the backrest bracket 1 common pivot axis, obliquely to the rear under the rear ends of the backrest bracket 1 and the seat plate 2, the first pair of struts 5 and the third pair of struts 7 in the same plane between the transverse axes 13 and 15 or their pivot axes on the backrest bracket 1 or Front leg pair 3, so that the plane also contains the transverse axis 12 or the common pivot axis of the three pairs of struts 5, 6 and 7 on the pair of sliding pieces 8 and crosses the surface of the pair of rear legs 4, the second pair of struts 6 approximately parallel to the seat plate 2 and the backrest bracket 1 and the seat plate 2 each approximately horizontally and only slightly rising or falling towards the rear end, the seat plate 2 resting on inner projections 20 of the pair of sliding pieces 8 or the second pair of struts
- the pair of sliding pieces 8 cannot move further down on the rear pair of legs 4 because it is connected to the front leg pair 3 both by the second pair of struts 6 and the seat plate 2 and by the third pair of struts 7.
- the backrest bracket 1 is supported on the front leg pair 3 and the first pair of struts 5.
- the backrest bracket 1, the seat plate 2, the front leg pair 3, the rear leg pair 4 and the three pairs of struts 5 to 7 pivot each other about the six pivot axes defined by the mutually parallel transverse axes 10 to 15, and finally the 2 or that of FIG. 1 or to get into the position of FIG. 8 or from the latter into that of FIG. 5.
- the pair of front legs 3, the rear legs 4 and the third pair of struts 7 of the folding chair according to FIGS. 1 to 3 are each formed by a U-shaped metal bracket, the transverse web of which serves as a base support.
- the two metal brackets of the front leg pair 3 and the rear leg pair 4 are at the upper ends of the longitudinal webs on one or the other side of the chair by means of a bearing block 21 screwed to the underside of the adjacent front end 1 'of the backrest bracket, a bearing pin 22 and two disks 23 with one another and with connected to the backrest bracket 1, the two bearing bolts 22 defining the transverse axis 10 or the corresponding pivot axis.
- the two metal brackets forming the pair of front legs 3 and the third pair of struts 7 are connected to one another at their lower transverse webs by means of plastic hinge pieces, each consisting of two halves 24a and 24b which are screwed together in order to rotatably accommodate the two said crossbars.
- the first pair of struts 5 is formed by two individual metal rods, each of which is connected to the backrest bracket at the upper end by means of a bearing block 25 screwed to the backrest bracket at the bottom, a bearing pin 26 and a washer 27, the two support pins 26 being the transverse axis 13 and the Define the corresponding swivel axis.
- the metal bracket of the front leg pair 3 has a cross strut 28 on which the seat plate 2 is rotatably mounted by means of tabs 29 screwed from below and which therefore defines the transverse axis 11 or the corresponding pivot axis.
- the second pair of struts 6 is also formed by a U-shaped metal bracket. Its transverse web is rotatably mounted on the underside of the seat plate 2 by means of screwed-on tabs 30 and defines the transverse axis 14 or the corresponding pivot axis.
- the ends of the longitudinal webs of this metal bracket are bent outwards to form the aforementioned internal projections 20, which are screwed at their ends to the sliding piece 8 on the respective chair side, in order to hold two bearing eyes 31 and 32 on the respective sliding piece 8, which open the same are rotatable and are provided on the adjacent ends of the first pair of struts 5 and the third pair of struts 7 on the relevant chair side.
- clamps 33 are expediently placed, which, like the hinge pieces 24a, 24b, are made of plastic, which dampens and prevents the folding chair from slipping on a smooth floor.
- the folding chair according to FIGS. 5 to 8 corresponds essentially to that of FIGS. 1 to 4 in terms of structure and mode of operation, apart from the special feature that the transverse axis 11 or the pivot axis of the seat plate 2 on the front leg pair 3 and the transverse axis 12 or the common one
- the pivot axis of the three pairs of struts 5, 6 and 7 are arranged on the pair of sliding pieces 8 such that the two transverse axes 11 and 12 or the two pivot axes coincide in the intermediate state according to FIG. 8 and in the transport or storage state according to FIG. 6 of the folding chair. It is therefore possible to fold the folding chair according to FIGS. 5 to 8 even further than that according to FIGS.
- FIGS. 5 to 8 The folding and unfolding of the folding chair according to FIGS. 5 to 8 is the same as for the folding chair according to FIGS. 1 to 4, apart from the fact that the seat plate 2 is still folded down at the end, as mentioned, or at the beginning first reversed from the position after Fig. 6 is folded up into that of FIG. 8.
- the transverse axis 11 or the pivot axis of the seat plate 2 on the front leg pair 3 is offset from the plane of the latter to the transverse axis 12 or to the common pivot axis of the three strut pairs 5, 6 and 7 on the pair of sliding pieces 8.
- the front leg pair 3 is provided with a U-shaped metal bracket, the transverse web of which forms the cross strut 28 discussed in connection with the folding chair according to FIGS. 1 to 4, and the two longitudinal webs of which are attached to the front leg pair 3 at the ends facing away from the transverse web. As shown, the metal bracket protrudes upward away from the pair of front legs 3.
- the seat plate 2 is also supported on the pair of sliding pieces 8 in the folding chair according to FIGS. 5 to 8 via the second pair of struts 6, but in a different way.
- the pair of struts 6 is in fact bent, so that there are two sections 6 'and 6 "enclosing an obtuse angle a, following the transverse axis 14 or the corresponding pivot axis or following the transverse axis 12 or the corresponding pivot axis 5 of the folding chair.
- the second section 6 "projects obliquely downwards from the seat plate 2 to the pair of sliding pieces 8.
- the second pair of struts 6 can be formed by a U-shaped metal bracket. To form the sections 6 'and 6 ", the two longitudinal webs are each bent accordingly.
