SECURITY SLEEPING

  The present invention relates to box springs or beds, in one piece or in two main parts, of the slat type, folding beds and weight machines.

comprising a folding bed base.

  There are many solutions of box springs made of wooden or flat metal slats connected by means of end caps to the two side members of a frame constituting the

remaining from the box spring.

  Also known in particular from French invention patents N 638,723 - N 7831673 - N 94 10142 - N 96 06709 folding beds equipped with four rollers moving in slides arranged on the two lateral sides of a box and thanks to a French patent application N 97 08640, a weight training device comprising in particular a folding bed base which allows, in an upright position, a person to hang on the upper crosspiece in order to perform physical training exercises and which allows , during the tilting operation of the bed base around a horizontal axis, to do weight training by exerting a couple on the bed base while holding said upper cross member; torque to which one or more energy absorbing devices is opposed. These different folding bed embodiments do not present risks for an isolated user, but a user can accidentally cause play, or even voluntarily, the jamming or shearing of the limbs of a person.

  carefree near the moving parts.

  One of the aims of the present invention is to provide greater safety in use on all the foldable beds plus an improvement to the aforementioned muscular apparatus by allowing, on the one hand, to have several levels for hanging and by making the apparatus accessible to people of different sizes, and on the other hand, to add degrees in the muscular exercises made more difficult as the couple exercises as close to the axis

of articulation of the box spring.

  Another object of the invention is to make it possible to produce all types of sturdy bed or box springs and of good firmness while avoiding nests as much as possible.

  dust and cellulose fibers appreciated by mites.

  According to the invention, these objects are achieved by means of a slatted bed base characterized in that the slats (1), in their greatest number, are produced in a flat tubular metal profile with flat, straight edges (2) or inclined (3), and / or rounded (4) and are connected by autogenous welding or by brazing

  directly on the two beams (5) of the bed base.

  According to a variant of the invention, several of said slats (1) are interconnected by tubular metal spacers (6) whose profile is similar to that of

  slats (1) and welded or brazed directly on said slats.

  In one application of the invention relating to a weight training device comprising a folding bed base, the slats in flat tubular section, of said bed base, will be

  preferably made with rounded edges.

  According to other applications of the invention relating to folding beds or to weight training machines comprising a folding bed base, and in order to avoid jamming of a person lying under the headboard during the end of the lifting the bed base, one or a few slats (7) located at the head of the bed base are assembled with the side members (5) and the uprights (8) using means (10,11,12) allowing the bedding to be held in all positions of the bed and allowing said slats (7) to retract or detach from the box spring in the event of encounter with a

  obstacle during the raising of the bed.

  Preferably, the applications of the invention relating to a folding bed or weight training apparatus of the type comprising four rollers (9,13) rolling in rectilinear slides (14,15) equipping the lateral sides of a frame will be made so that the slides (14) located at the rear of the frame are parallel to the junction plane of the frame with the wall, so that no wedging between the movable part and the

wall cannot be possible.

  Similarly, to avoid jamming, the means of compensation and / or - 3 - of energy absorption (16) equipping the applications mentioned above are partially or entirely wrapped by the slides (14) made in the form of C To partially ensure the balance of the movable part, these latter applications use as means of compensation and / or energy absorption (16) gas springs containing a large volume of liquid and these act in or near the vertical plane containing the axes of the slides (14). For these latter applications, by favoring ease of manufacture or even aesthetics, it is convenient for the axes of the other rectilinear slides (15) to be located in a

same horizontal plane.

  Finally, to obtain an improved balance of the movable part equipping the folding beds or bodybuilding apparatus, the compensation and / or energy absorption means (16) comprise on either side of the frame at least two springs to gas (17,18), containing a large volume of liquid, mounted one behind the other and in alignment with their longitudinal axis. Preferably, in order to mitigate the possible buckling of the gas springs (17,18 ) mounted in the same alignment, one or more intermediate elements (19) slide inside the slides (14) and keep their ends in the axis of the gas springs (17,18)

who join.

  Applications designed according to the invention have a number of advantages. All these applications contribute to a coating of good firmness, solid, hypoallergenic, and of great safety of use. They can be made in two removable parts to facilitate their transport. There are additional advantages of the weight system, such as allowing people of different sizes to use it and thus stay

  usable throughout a child's growth.

  It goes without saying that it is not departing from the scope of the invention if the bed base with metal slats with a flat tubular profile is fitted to any type of bed other than those already mentioned, such as, for example, hinged bed frames, pull-out or bunk beds. , etc. In the following, the invention is explained in more detail with the aid of the accompanying drawings.

  representing an embodiment of the invention.

  Figures 1,2,3 show in section flat tubular metal profiles with

different songs.

  Figure 4 shows in perspective a weight training machine with a box spring

  folding, two-seater, presented in the high position.

  Figure 5 is a sectional view showing one of the rollers (13) circulating in one of the

  slides (15), the base being in a horizontal position.

  Figures 6 and 7 are sectional views showing the joint of the end

  upper of one of the gas springs in the slide (14).

  Figure 8 is a sectional view showing one of the rollers (9) circulating in a

  slide (14) as well as the articulation of the rod end of the gas spring.

  Figures 9 and 10 show a guide solution in the slides (14) of the intermediate parts (19) connecting the ends of the gas springs (17,18) mounted

  in the same alignment to improve the balance of the moving part.

  With reference to these drawings, the tilting bed and weight training apparatus, produced in accordance with the invention, includes a slatted base shown in position

vertical in Figure 4.

  On this base are articulated two mainly bearing rollers (13) rolling in horizontal slides (15) and two rather centering rollers (9) rolling in

vertical slides (14).

  These slides constitute the essential elements of a mechanically welded frame bearing on the ground by two feet (40) and sealed to the wall by four fixing plates (41). Additional elements (42,43) prevent the penetration by the sides of body parts of users in front of the moving parts of the bed, while three

  crosspieces (44) ensure the parallelism of the roller tracks.

  The box spring is made in two main parts assembled by four bolts

  (45) in order to reduce costs and facilitate packaging and transport.

  Each of the parts consists of two longitudinal members (5) joined together by metal slats (1) produced from a flat tubular section (4) with rounded edges welded directly to the longitudinal members (5). Some of these slats are joined together by elements (6) of the same profile. The upper part of the box spring

  receives a pivoting foot (46) which partly allows the sleeping mattress to be held.

  The head of the bed base receives a tube (30) which is aligned with the axes of the rollers (9) and connected to the side members (5) by uprights (8). This tube therefore moves in a plane parallel to the wall, supporting any pillows or bolster without risk of jamming or pinching of a third person. The first slat (7) of the headboard is removable. Two pieces (1) cut from a sheet close the ends of the slat (7) and each form a hook-like protruding part which takes place in a fastener (10) produced by a curved wire welded to the spar (5). Two other curved wires (12) whose function is to support the mattress in the vertical position are welded to the batten (7) and bear on the uprights (8). Thus, if a person is lying below the bed and close to the wall, the ascent of the bed could be done without danger for him because the slat (7) would retract in the event of an encounter. To complete the safety, a casing (47) acts as a deflector to avoid a possible jamming between the ground and the side members (5) and prevents access to the interior of the

slides (15).

  In this weight training bed application, the means of energy compensation and absorption use on each side of the bed a simple gas spring (16) filled in good part with oil and the two chambers of the cylinders of which communicate through of a sufficiently narrow orifice. The cylinder of the gas spring (16) is articulated in the upper part as shown in Figures 6 and 7, by means of a bolt (35,36). A cross made by the parts (37,38) ensure the resistance to bending of this joint. A tip (39) covers the slide (14). Figure 8 shows the articulation of the gas spring rod (16) in the same axis as the centering roller (9). This last articulation is constituted by a screw (31) blocked at the end by a locking washer (34) on a stop (33) welded on the axis (29) of the roller.

  centralizer (9). A washer (32) with chamfer is attached to the screw (31).

  The minimum effort required to open the bed, prescribed by the standards in force, conditions the minimum effort that each of the gas springs must provide in the extended rod position. and therefore the initial internal pressure of the gas spring. In the horizontal position, it is not necessary that under the action of a minimum force, at the head of the bed base and prescribed by the standards, the bed base is raised. This last condition limits the force of the spring to - 6- gas, in the retracted rod position, which makes it possible to deduce the maximum internal pressure then the volume of oil required using the ideal gas law:

p. v = constant.

  The balance is not ideal, but the narrowness of the orifice that separates the two chambers of the gas spring takes care of absorbing enough energy for the energy

  residual opening is within the limits allowed by the standards.

  A better balance is obtained by using more than one gas spring on each side of the box spring aligned in the same longitudinal axis and which are interconnected as shown in Figures 9 and 10 by a shoe (19) sliding at the inside of the slide (14) and by pins (20). In this way, the minimum pressure located in the gas spring having the lowest force in the extended rod position as well as the maximum pressure located in the gas spring having the greatest force in the retracted rod position is calculated from the same way as before. The intermediate values allow the fairest balance between the torque produced by the moving part (box spring

  + bedding) and the opposite couple by the gas springs.

  The rollers (13), which can be described as carriers since they support the greatest forces opposing both those caused by the weight of the moving part and those caused by the thrust of the gas springs , are articulated on an axis (22) and on a self-lubricating ring (23) as shown in Figure 5. The axial stop of the roller (13) is effected on the one hand by the wing of the C-section of the slide (15) and on the other hand

  by the washer (24) fixed to the axis (22) by the screw (25) and the lock washer (26).

  A screw handle (27), incompletely shown, allows the mobile assembly to be locked in the high position as in the low position, since the horizontal position of the bed base stopped by the pivoting foot brought into position and the vertical position of the bed base determined by the gas springs any extended rod have been designed so that

  the rollers (13) occupy the same position.

  Safety beds, particularly those with a folding bed base, are intended to equip the rooms or studios of individuals as well as those of collective premises such as

that prisons, barracks, boarding schools ...
