  • the invention relates to a security device for a rack formed by notches capable of retaining a cross member, and in particular a rack for a chaise longue.
  • a lounge chair consists of two large uprights connected by two large crosspieces, each of these large amounts being articulated on another amount, carrying a rack. Between the amounts to rack, two small sleepers are placed. A strip of canvas is fixed on the one hand, to a small cross and on the other hand, to a large cross.
  • small amounts are hinged on the large uprights, on the side of the large cross member which is fixed the canvas strip. Opposite of their articulation point on large amounts, small amounts are connected by a cross which is intended for be placed in a rack provided in each rack upright, on the side of the small cross member opposite to that on which the canvas strip is fixed.
  • this crosspiece in the rack and pinion is not always very easy.
  • the cross member of small upright tends to disengage one or both racks when a person, sitting in the lounge chair, moving slightly or even when the lounge chair is moved.
  • the document GB-429,966 describes a device stop for chaise longue which is intended to be fixed in look of at least one notch of the rack the amount of the lounge chair.
  • the stop device For each notch, the stop device has an inverted L shape, fixed on a base, this which spares a cavity for the crosspiece.
  • the horizontal branch of L is used to block the crosspiece.
  • the invention aims to overcome these drawbacks by proposing a safety device for a rack formed of notches capable of retaining a cross member, and including a lounge chair rack, ensuring effective blocking of the cross member, especially when the deck chair is moved, avoiding the presence of protruding parts which could injure the user and finally, not interfering with the storage of deckchairs.
  • the invention relates to a security device for a rack formed by notches capable of retain a cross member, said notches comprising a ramp and a stop, and in particular for a chair rack long, characterized in that it is constituted by a part mounted to pivot freely on the side of at least a notch and comprising a notch capable of receiving said cross member, this notch being defined by a side, by a hook-shaped part and the other side, by a ramp-shaped part towards which is bent the hook, and in that the axis of pivoting of said part is located in such a place that in the rest position, the ramp-shaped part is, under the effect of gravity, protruding from the ramp of said notch, while the shaped part hook allows the insertion of said crosspiece, and such that, when inserted into said notch of the rack, the cross rests on the part in workpiece ramp and causes the hook to tilt which closes on the crosspiece.
  • the part has an imbalance.
  • the part has a general V-shape or the like with one branch extends to constitute said part in the form of hook, bent towards the other branch.
  • the point of the V advantageously constitutes the imbalance of said piece.
  • the pivot axis of the part is located substantially under a middle part between the ramp and the stop of said notch.
  • the hook defines a cavity for the crosspiece whose diameter is slightly greater than the cross section and whose entry section is less than the cross section.
  • the end of the hook forms a protuberance.
  • the part is made of a strong and elastic material, such as polypropylene or nylon.
  • the invention also relates to a lounge chair comprising at least two uprights, each of them presenting a rack made up of notches, on which at least one safety device according to the invention is mounted freely pivoting on the side of a said notches.
  • each safety device is mounted on the internal lateral face of a rack upright.
  • Figure 1 shows a lounge chair in position unfolded and comprising safety devices according to the invention.
  • FIG. 2 represents a rack, for example of a lounge chair, as provided in the state of the technical.
  • Figure 3 illustrates an example of a safety device according to the invention.
  • Figure 4 is a perspective view showing a safety device according to the invention mounted on a rack and in the rest position.
  • FIG. 5 is a front view of a device for safety according to the invention mounted on a rack and in the rest position.
  • FIG. 6 is a perspective view of a device for safety mounted on a rack and in position blocking on a crosspiece.
  • FIG. 7 is a front view of a device for safety according to the invention mounted on a rack and in the locked position on a cross member.
  • Figure 8 is a partial perspective view of a lounge chair fitted with safety devices according to the invention, in the folded and vertical position.
  • Figure 1 illustrates a lounge chair that has two large uprights 1 and 2 parallel which are connected to proximity of each of their ends, by two large sleepers 3 and 4.
  • the lounge chair also includes two uprights rack 5 and 6. These two uprights are parallel and have, on the side of one of their ends a rack 9, 10.
  • Each of the rack uprights 5, 6 is pivotally mounted on one of the large uprights 1, 2, around an axis 12.
  • a strip of fabric 13, corresponding substantially to the distance between the rack uprights 5, 6, is fixed on the one hand, to the small crosspiece (not shown) located at opposite of the small cross member 11 and on the other hand, at the large cross 4.
  • the small uprights 14, 15 are pivotally mounted on each of the uprights 1, 2, around an axis 16 parallel to axis 12 and placed on the side of the large cross 4.
  • the small uprights 14 and 15 are connected by a crosspiece 17.
  • FIG 2 partially shows an amount to rack, such as the one bearing the reference 6 on the Figure 1 and on which no safety device is planned.
  • This amount 6 comprises several successive notches 18, the number of notches being chosen according to the number of different positions which is provided for the lounge chair in the unfolded position.
  • Each notch 18 has a ramp 18a and a stop 18b.
  • the crosspiece 17 illustrated in the different figures has a round section. Conventionally, the notch depth 18, 19 is relatively small by compared to cross section 17.
  • FIGS. 4 and 5 illustrate a safety device according to the invention which is fixed on a rack upright, for example upright 6.
  • the safety device 20 is shown on an extended lounge chair resting on the floor S, and in the rest position, i.e. a position in which the crosspiece 17 is engaged neither in the notch 18 of the rack 10, nor in the device for security.
  • the safety device 20 is mounted on the internal lateral face 6a of the rack upright 6, especially to be as discreet as possible.
  • This security device 20 consists of a part which is freely pivotally mounted on the face 6a and therefore on the side of the notch 18, around a pivot axis 30.
  • this part 20 includes a notch 21 which is defined on one side by a part in hook shape 22 which is suitable for receiving the cross member 17 and on the other side, by a ramp-shaped part 23, in the direction of which the hook is bent.
  • the pivot axis 30 of the part 20 is located at a place such that, in the rest position illustrated in Figures 4 and 5, the ramp-shaped portion 23 is in projection relative to the ramp 18a of the notch 18.
  • the part in hook shape 22 allows the insertion of the crosspiece 17, the notch 21 being open on the side of the crosspiece 17.
  • This position of the part 20 relative to the notch 18 is obtained under the effect of gravity, thanks in particular to the positioning of the axis 30 on the upright 6.
  • the part 20 has a general V-shape or the like, one of which branch extends to form part 22 in shape hook which is bent towards the other branch of the V.
  • V-shaped part and in particular the tip of the V constitutes an unbalance which makes it possible to place, at rest, the part 20 in the position illustrated in FIGS. 4 and 5, relative to notch 18.
  • the invention is of course not limited to this form Part 20.
  • the lounge chair is always unfolded, we choose the position in which it must be fixed in determining the appropriate notches 18, 19 of the racks 10 and 9. Description of the operation of the device security 20 will only be described with reference to notch 18.
  • the cross member 17 slides on the upright 6 and engages on the ramp 18a of notch 18.
  • the cross member 17 then necessarily rests on the ramp part 23 of part 20, which causes the tilting of the hook 22 which closes on the cross 17.
  • the hook 22 defines a cavity 25 for the cross member 17 whose diameter 25a is slightly greater than the section of the crosspiece 17 and whose entry section 25b is less than the cross section of the cross member 17.
  • the crosspiece 17 can cross the entry section 25b, thanks to the elastic nature of the material constituting the part 20, and then it is placed in the cavity 25.
  • This entry section 25b like the end 26 of the hook 22 which forms a protuberance, contributes to the blocking of the crossmember by the safety device 20.
  • the security device 20 makes it possible to block effectively crosses it 17 in a notch of a rack.
  • the safety device according to the invention has made subject to mechanical testing according to procedures described in standard XP D 616062 (furniture outdoor). These tests have shown that the security according to the invention fulfilled all requirements of this standard.
  • Figure 8 shows that in the folded position, here vertical, the safety devices 20 do not have no protruding part which can cause the stacking of loungers or injuring a user, since hooks 22 are tilted against the upright 6.
