Definitions

  • the present invention relates to a relaxation furniture or light sleeper device, thin in its members, stable and easily stackable, comprising a frame provided with a front foot system and a double base system at the rear on the head side, the plane of the front leg being perpendicular to each of the rear legs.
  • An enveloping canvas is associated with the frame on which the user can relax.
  • the entire chassis constitutes a single horizontal plane which is rigid.
  • the chassis is identical, completed by a second movable assembly forming a backsplash articulated transversely on it at approximately 1/3 rear to evolve at will from a straight rectilinear part similar to the simplified model towards all the raised positions where the relaxation furniture constitutes a lounge chair.
  • GB 2168890 A tubular canvas frame at the feet forming two stackable W arches, without backsplash; its two ends constitute cantilevers on which it is excluded to sit; the whole is subjected defenselessly to the pulls of the canvas under load which accentuates the progressive lateral spacing of these two W.
  • FR 2465443 shows a heavy frame having overlapping shapes but cluttered with slats which imply a cushion and the presence of the wheels prevents any prospect of overlapping in a small volume.
  • US 4264102 With the same characteristics as the previous one, if it is articulated, it cannot be straight or stackable.
  • this relaxation furniture It is light, nevertheless rigid and resistant so that a canvas stretched over the frame advantageously replaces the usual slats and mattresses.
  • the conformation of this piece of furniture allows the use of a tube of reduced diameter to result in a stack of very small dimensions without disadvantages for its height on feet. Its stability is increased by the fact that its feet are connected together in pairs and that the plane of the front ones is orthogonal to those of the two rear legs on the head side.
  • the invention therefore relates to a relaxation furniture that can form a berth or chaise longue comprising a bed frame, two front legs and two rear double legs, the furniture stacking on top of each other with minimal bulk and in a direction of stacking perpendicular to the plane of the bed, characterized in that each of the two rear legs consists of a tube having a shape similar to a U or a W, the lower part of which is in contact with the ground, the first of the ends of the U or W is connected to the rear end of a lower side forming the frame, the second rising end of which is connected to said frame at the junction point, and in that the two front feet consist of a bar tubular having a shape similar to a U or W, the lower part coming into contact with the ground, each of the two ends of the U or W being connected to the lower side so that the plane co now the front legs is perpendicular to each of the two planes containing the rear legs (and possibly the armrests), the sides of the legs and the armrests being inclined longitudinally with respect
  • this piece of furniture consists of a first part, a second part and a third part, the first part comprising two horizontal tubes situated on either side of the berth and over its entire length and forming the lower sides, each tube being connected to the ends of the front leg by an elbow in the direction of the ground to then join, the second part being in the shape of a U and integral with the first part, the two sides of the U being placed side by side on the lower sides, the bottom of the U forming a horizontal cross-piece uniting at the same time the tubes of the first part on the front part of the bed, the ends of the bars of the U ending backwards near the connection point of the rear legs, the third part forming the rear legs of the bunk connected together by the crossmember.
  • the bars of the U continue to the rear and form a horizontal crossbar at the level of the user's head.
  • this piece of furniture has a backsplash which is articulated on the second part to about 1/3 of its total length towards the rear and it is formed of a U, the bottom of which constitutes a crosspiece situated at the end of the furniture on the head side and the sides of the U having the same spacing as the tubes of the first and second parts, its two uprights having their end articulated on the end of the second part, it is designed so that in the folded position in the plan of the berth, it also lets pass on both sides the feet of the identical piece of furniture placed on it.
  • the invention will be clearly understood with the aid of the following nonlimiting example of embodiment which begins with a chassis shown in FIGS. 2 and 5 composed of three parts.
  • the first part, main frame consists of a tube in the form of a symmetrical fork, the horns of which form two parallel and horizontal sides (1), hereinafter called the lower sides, their two ends will be fixed or preferably welded to the crosspiece (10) of the third part described below, the tubes are spaced to obtain the comfortable width of a bed.
  • these two sides are bent at the bending points (2) downwards to form with the ground the type of stacking angle and at the same time according to some variant an angle lateral to the length of the bed from 5 to 20 ° outwards, these two sides thus form the two uprights (3) which constitute the front base in the shape of a trapezoid and the plane of which is inclined according to the stacking angle.
  • These two uprights are bent at the bending point (4) to form the crosspiece (5) which constitutes the base of the trapezoid which can be arched with the arrow (5a), details given at the end with all the usual dimensions.
  • the second part or doubling of the main frame is a U-shaped tube, the foot of the U which constitutes the front crosspiece (7) of the frame, see Fig 7, is rectilinear and horizontal, bent on each side at the bending points (2 bis) at 90 °.
  • the U-shaped tube has two sides which rest on the upper part of the lower sides of the first part of which it has the same width. It ends at the junction point (16) for the version equipped with a backsplash, see Fig 2, or continues along a straight line by the sides (6 bis), by the two hangers (19 bis) and by the crosspiece head (21a) for the simple version, see Fig 1.
  • This second part then forms a quadrilateral which is superimposed on the main frame.
  • the main frame and its lining are thus assembled by welding or any other means of fixing, continuously or at a few points and receive on both sides hangers (2 and 2a), gussets ( 36 ) in the shape of a butt which contribute to reinforcing the inclined legs and must by their position and shape ensure the superposition of the berths, the guidance and the vertical setting in the stacking direction.
  • the third part also called double head base, consists of the two rear legs secured to the crosspiece (10) which connects them on their rear part.
  • Each rear leg is made up of a tube whose shape is close to a capital U or W; the central part of the feet coming into contact with the ground consists of an arc of a circle or a flat part connected to two hangers giving a U shape.
  • This part (14) can also be bent upwards in the middle forming an arrow (14a) giving a shape of W.
  • the ends of the rear uprights of the U or W forming each base are connected to the rear end of the lower side (1).
  • the ends of the front uprights of the U or W are connected to the double frame at the junction point (16).
  • the junction point (16) is the area where the lower side (1) and the upper side (6) cross the upright (15), the front part of the rear base. It is located about 1/3 of the length of the berth, rear side which is the side where the head of the user is located.
  • this third part consists of a single tube bent at two bending points (11) meeting the crosspiece (10) of the end of the rear side of the base (13) and joins the end rear side (1). This tube is then bent to meet the rear side (13) and the front side (15) in one go, arc of a circle, or in two times forming a flat part (14) with two hangers (12 and 12 bis) or in three times with arrow up (14 bis).
  • the front leg of the first part is in a plane perpendicular to those defined by the rear legs. These two vertical planes are spaced 15 m / m (thickness of the hold) from the lower sides, to be parallel to them.
  • the uprights (15) are fixed by means of a shim ('17) machined or cast which saves between them a space of about 15 m / m for allow the passage of the legs on either side of the frame of another berth in posi stacked.
  • armrests can be widened and reinforced using a doubling of identical shape (35) which has one end (30 bis) beyond the junction point (16) on the upright (15) and the other ( 33a) in the vicinity of the hanger (31a).
  • the inclination of the uprights (30 and 33) is preferably identical to that of the feet for the direction of vertical stacking.
  • the sides of the front leg (3) and the rising sides of the rear legs (13 and 15) as well as the armrests (30 and 33) form an angle with the stacking direction which, according to a preferred embodiment, is perpendicular to the plan of the berth part of the cabinet.
  • these parts must make an acute angle less than 20 ° and greater than 30 °, which is a function of the thickness of the adopted part.
  • the angle between the horizontal plane of the berth and the uprights front feet, rear base and possibly armrests is close to 60 to 65 °, ideal angle so that each upper part of a berth comes into contact in at the same time with each corresponding lower part of the furniture fitted above.
  • the articulated and adjustable backsplash (Fig 7 plan, Fig 3 and 4 from the front and in a horizontal position, Fig 5 face position of the backsplash raised by 25 ° as Fig 2 in profile) is like the second part, a U-shaped tube whose the bottom constitutes the head crosspiece (21) and is bent at 90 ° at the bending point (11) to form the two sides (20) which are parallel to each other and of the same width as the frame.
  • the backsplash is symmetrically opposite the second piece at the end of which it is articulated by two hinges on the axis (22) allowing it to rise at will in the chaise longue position.
  • a reinforcement crosspiece (23) parallel to the crosspiece (21) is fixed on the sides (20), flattened at the ends to serve as a shim between the lower sides (1) and the sides (20) which protects the canvas .
  • This crosspiece (23) is offset downward, it constitutes with the sides (20) and the head crosspiece (21) the housing of a cushion, it strengthens the assembly and gives support to the top of the crutch defined above. below (assembly 50, Fig 8) by serving as a bearing.
  • the central chassis crossmember (particularly visible in Fig 4, 5 and 7) consists of a U-shaped tube oriented in the same direction as the backsplash (8) and following. Its two sides (9) are housed and welded in the grooves formed between the sides of the frame (1 and 6) in the area of the junction point (16). They are bent at 90 ° at (9 bis) to form the crosspiece (8).
  • the middle of this crosspiece having the function of bearing for the stand (28) of the crutch (50) and to enable it to provide the concentric support necessary for all the inclinations of the backsplash, it must be positioned with an offset (18) behind the axis of articulation (22) of the backsplash and another offset (18 bis) downwards by means of two light hangers (8 bis) on the crosspiece (8).
  • This cross member is also a longitudinal reinforcement at the junction point (16) and allows the frame to resist the embrace of the canvas when fully loaded. In stacking, this downward protrusion is easily absorbed by the flexibility of the fabric of any berth located below.
  • a telescopic stand (50) is automatically locked by compression. Its choice is decisive for the practical operation of the backsplash and especially for its small size with regard to the desired stacking.
  • the stand (50) consists of three tubes circulating one inside the other:
  • the first outer tube is the cylinder (25), its end is introduced integrally into the foot of a tubular T (28) whose bottoms are slotted to form a connecting rod head, articulated on the center of the central crosspiece (8) of the chassis to serve as support and bearing.
  • the second tube freely circulating in the cylinder is the piston (26), its projecting end is also fixed in another T (29) which likewise takes support in the center of the cross of the backsplash (23).
  • the parts (28 and 29) are kept in alignment by the clips (39).
  • the part (29) and the crosspiece (21) have an orifice (41) in the extension of the piston to deliver passage to the pusher defined below.
  • the piston houses at its other end a known mechanical blocking system (40) which blocks it in the compression direction inside the cylinder by means of either: cone, eccentric, ball or the like, leaving it free in the opposite direction . It allows the backsplash to be raised and locked in any desired position, following the arc (24) around the axis (22).
  • the third is the pusher (27). Small in diameter, it penetrates inside the piston (26) through the orifice (41), produced in its extension, it is guided by a centering ring (42) up to the mechanical locking system (40) that 'he is responsible for locking.
  • the pusher is extended by a rod (27 ter) very slightly articulated with its end (27), inside the part (29) to reach the crosspiece (21) which it pierces, the rod ends with a button (27 a).
  • a simple press on this very accessible button triggers the release and allows the backrest to descend.
  • the interlining must be particularly comfortable and easy to maintain, but its description goes beyond the scope of the invention.
  • a practical vehicle for picking up large numbers of berths is easily achievable, starting from any standard berth on which an axle is fitted which finds its place between the gussets ( 37 ) which connect at the level of the hanger ( 12) the upright (13) and the crosspiece (14), equipped with two standard wheels whose dimensions are variable depending on the nature of the ground.
  • On bumpy, soft ground (47), significantly higher wheels (49) are fitted with large tires and located outside of said legs to increase stability. It is thus possible by taking the crosspiece of the feet before easily pulling a stack of 15 berths (Fig 14), very securely nested with for total height 1 m 20 and less than 100 Kgs.
  • the tubes are made of light metal such as aluminum alloy, have a diameter of 20 m / m and a section of 1.5 to 2 m / m.
  • the furniture is about 2 m long, 0.70 wide overall and 0.30 to 0.40 high.
  • the aluminum gussets or reinforcement plates are 3 to 5 m / m thick.
  • the weight provided for its whole: chassis, stand, canvas and elastics is 5 to 6 Kgs.
  • the backsplash which is about 0.70 long.
  • the optional armrests will be 18 to 20 cm apart from the frame and will be 25 to 30 cm long.
  • the crosspieces of the front (5) and rear (14) legs have hangers in their middle which give the ground an arrow (5 bis and 14 bis) of 4 to 5 cm for better reach.
  • the intermediate cross of the backsplash which is offset downwards by 3 cm without harming the stacking, lets the lacing of the pillow pass over it.
  • the central cross member of the chassis is 40 to 50 cm long, its rearward offset is 10 to 12 cm and downward from 6 to 8 cm.
  • the shims ( 17 and 34 ) give the tubes which connect with them a spacing of 15 m / m (F in Fig 9), determining for the nesting of the rear legs.
  • the cylinder is 20 m / m in diameter
  • the piston 16 m / m the pusher 8 to 10 m / m and the rod approximately 6 m / m
