LOUNGER

Abstract: The invention relates to a lounger comprising a seating part (7) with two legs (1) on each side, which parts are hingedly connected with each other with a leg on each side so connected with the seating part by means of a pin as to allow it to be turned, the seating part being adjustable for height. Each backmost leg is provided on its side facing the seat with a first guideway (2) and a first pin (6) and the sides of the seat with a second guideway (8) and a second pin (14), which second guideway is provided with a number of stops (12, 13) positioned at intervals from each other for the first pin, at which, when the first pin rests against a first stop (12), the seating part of the lounger takes a position different in height from that in which the first pin rests against another stop (13) and at which in every position in which the pin rests against a stop, and in every intermediate position, the second pin is free from the first guideway, and at which, when the lounger is folded up or unfolded, the second pin will be moving in the first guideway, while the first pin will be free from the second guideway.

Description: LOUNGER The invention relates to a lounger comprising a seating part with two legs on each side, which parts are hingedly connected with each other, with a leg on each side so connected with the seating part as to allow it to be turned, and which seating part is adjustable for height. Such a lounger is known from the German Offen- legungsschrift 3.127.310. That lounger, too, is provided with a seating part adjustable for height, which seating part is capable of being adjusted for height in that at the front of the seating part a number of cams are provided cooperating with pins provided at the ends of the legs ending at the front of the seating part. By causing the pins to be engaged behind a set of cams the lounger is locked in a certain position and the seating part then assumes a certain height in relation to the floor. By causing the pins to be engaged behind a set of following cams, the seating part assumes a different height and the lounger is locked in this position. Of the legs one end rests on the floor, the other is connected with the seating part, while the armrests are connected with the seating part with separate armrest supports. The lounger is provided with an adjustable backrest hingedly connected with the seating part and with the armrests. The lounger is of a rather complicated design and another disadvantage is that, when the lounger is folded up, no compact whole is formed, so that a relatively large amount of storage space is taken up in both horizontal and vertical position. Another disadvantage is that frequent use of the lounger causes the adjusting pins and cams to wear out, which will make the safe use of the lounger problematical in the long run. The object of the invention is to provide a lounger with a seating part adjustable for height which does not have said disadvantages. According to the invention this is achieved in that each backmost leg is provided on its side facing the seating part with a first guideway and a first pin and the sides of the seat with a second guideway and a second pin, which second guideway is provided with a number of stops positioned at intervals from each other for the first pin, at which, when the first pin rests against a first stop, the seating part of the lounger takes a position different in height from that in which the first pin rests against another stop and at which in every position in which the pin rests against a stop, and in every intermediate position, the second pin is free from the first guideway, and at which, when the lounger is folded up or unfolded, the second pin will be moving in the first guideway, while the first pin will be free from the second guideway. With the lounger according to the invention the stops for the respective pins are so designed that they partly surround the circumference of the pins. This will prevent the pins from slipping out of the stops, whereby the safe use of the lounger is guaranteed. The first and the second guideway consist of parallel raised ribs situated at some distance from each other providing a fit, with a small amount of clearance, for the second and for the first pin respectively. If so desired, an extension may be coupled in a simple manner to the front of the lounger to serve as a legrest. If this extension is not used, it may be fastened to the back of the backrest in a simple manner. To this end the extension is provided with a lug to enable it to be clicked on to the backrest. With the lounger folded up, the second pin rests against the stop of the first guideway. Then the first pin is entirely free from the second guideway. In this position the lounger forms a compact whole that can easily be stored away in its vertical position. In the folded-up. position the front and back legs are parallel to each other. When the lounger is unfolded, the second pin in the first guideway moves to the free opening thereof, while simultaneously the first pin is moved in front of the free opening of the second guideway. As the unfolding continues the second pin leaves the first guideway and the first pin moves into the second guideway until this first pin comes to rest against the first or the second stop in this second guideway. The lounger is now unfolded and locked with its seating part in its high or low position. The adjustment of the seating part from one position into another is effected by folding up the back legs of the lounger so far that the first pin is released from the first stop in the second guideway and, by unfolding the back legs again, is moved in this guideway until the first pin rests against the other stop in the second guideway. The seating part will then be in a different position. The lounger is folded up or brought into its high position again by reversing the order. The lounger according to the invention is suited, for instance, for use as garden lounger and may be made entirely of plastic. A highly suitable plastic is polypropylene. Other characteristics and advantages will be clear from the description below, for which reference is made to the attached drawings. Herein: Fig. 1 is a view of a part of a leg of a lounger provided with a first guideway and a first pin according to the invention; Fig. 2 is a view of a part of one of the sides of the seating part provided with a second guideway and a second pin, as well as a first and a second stop for the first pin; Fig. 3 shows a part of the lounger in folded-up position with the second pin resting against a third stop o the first guideway and the first pin free from the second guideway; Fig. 4 shows a part of the lounger in unfolded position with the first pin of the first guideway resting against the first stop of the second guideway, the lounger being in its so-called high position; Fig. 5 shows a part of the lounger in unfolded position with the first pin of the first guideway resting against the second stop of the second guideway, the lounger being in its so-called low position; Fig. 6 shows a part of the lounger with the first pin free from the second guideway and the second pin moving into or out of the first guideway; a position created when the lounger is folded up or unfolded, or when the seating part is adjusted from its high to its low position or vice versa. In Fig. 1, 1 is one of the back legs of a lounger provided on the side facing the seating part with a first guideway 2 built up of parallel raised ribs 3 and 4 which merge at one end and form a stop 5 (third stop) for a pin. - Leg 1 is provided on the same side with a first pin 6, which pin 6 extends, in relation to the wall of leg 1, beyond raised ribs 3 and 4. In Fig. 2 a part of seating part 7 is shown provided on its sides with a second guideway 8 again consisting of raised ribs 9 and 10, which leave a passage 11 at the front and are provided on that side also with a first stop 12 for receiving the first pin 6. At the back, ribs 9 and 10 merge and at that place form a second stop 13 for the first pin 6. This will be elucidated in the description of the next figures. Near the first stop 12 a pin 14 (second pin) is provided extending, in relation to the wall of seating part 7, beyond raised ribs 9 and 10. In Fig. 3 the position of the leg and seating part according to figures 1 and 2 is shown with the lounger in its folded-up position. The figure shows (partly) that in its folded-up position back leg 1 is virtually parallel to seating part 7. In this position the second pin.14 rests against stop 5 of the first guideway 2, while the first pin 6 is entirely free from the second guideway 8. When unfolding the lounger, the second pin 14 leaves stop 5 of the first guideway 2 and moves via this guideway to the open end 15 thereof and leaves the guideway via the curved extension 16 (see also fig. 6), while at that moment the first pin 6 is to be found at the free opening 11 of the second guideway (fig. 6) so as to be placed against stop 12 as the unfolding continues. The lounger is unfolded now and, as shown in fig. 4, seating part 7 is in one of the two positions into which seating part 7 of the lounger can be placed. The position taken by seating part 7 in fig. 4 is the highest position that can be taken. In order to adjust the seating part from its high position shown in fig. 4 to its low position shown in fig. 5, it will suffice to fold the backmost legs 8 so far that the first pin 6 is released from stop 12 to move into the second guideway 8 and subsequently, by unfolding back legs 1 again, via this second guideway 8 to move on to stop 13. Seating part 1 is then in its low position. Fig. 5 clearly shows that in this position legs 1 form a smaller angle with the horizontal (floor surface) than legs 1 in the position shown in fig. 4. As a result, seating part 7 is closer to the floor surface. The position shown in fig. 6 (briefly referred to above) is an intermediate position, which occurs when the lounger is being folded up or unfolded, or when the seating part 7 is being adjusted from its high to its low position, or vice versa. The figure shows that in this position the first pin 6 is situated at opening 11 of the second guideway 8, while the second pin 14 is free from the curved extension 16 of the first guideway 2 , so free from the first guideway. In this position the lounger can be folded up; this is done by raising seat 7 at its front, which causes the second pin 14 to move into the first guideway 2 as far as stop 5, or the seating part 7 can be adjusted into its low position by pushing against the back of the seat and simultaneously moving the back legs backwards, which causes the first pin to move via guideway 8 to stop 13. The lounger is folded up or the seating part is adjusted again into its high position by reversing the order. The lounger according to the invention is preferably suited as garden lounger and may be provided with an adjustable backrest 17. The adjustment of the backrest is done as known by lifting the armrests and moving these forwards or backwards and by subsequently lowering them again. The lounger may be provided at the front of the seating part with an extension that can easily be connected to it to serve as a legrest. This is of particular advantage when the seating part is placed in its low position, so that a deck chair is obtained. After its disconnection, the extension serving as a legrest can easily be fastened to the back of the backrest. To this end the extension is provided with a springing lug to enable it to be easily clicked on to the backrest.
