Definitions
- the Murphy bed presented in this document has the drawback, however, that if the handle unlocking of the locks is activated inadvertently during that the bed is loaded, and in particular when this bed supports a person sitting or lying down, then the bed frame suddenly collapses.
- the object of the present invention is in particular to overcome these drawbacks.
- a retractable bed of the genre in question is essentially characterized in that that the locks allow some sliding play to second pivots between the stop portion of said latches and the second stop position of the second pivots, the assistance means being provided to make up for this play by lifting the frame to place the second pivots in their second stop position when the frame is in raised position and the bed not loaded, and said means assistance also being designed to leave the frame lower slightly so that the second pivots abut against the respective stop edges of latches when the frame is in the raised position and the bed supports a predetermined load, and in that the stop edge of each lock has a share a contact area against which the second corresponding pivot when the frame is in raised position and the bed supports said load predetermined, and on the other hand a protruding area which is disposed between the contact area and the cam edge and which protrudes toward the second stop position of the second pivot from the contact area, this protruding area being designed to cooperate with the second pivot in preventing the latch from pivoting to its cleared position when
- the retractable bed 1 comprises a rigid bed frame 4 of rectangular shape, which extends horizontally and which has the first and second longitudinal sides 5, 6 as well as two transverse sides 7, only one of which is visible on the drawings, this bed frame supporting a mattress 8 ( Figure 1), for example through slats 9 whose ends are fixed respectively to longitudinal sides 5, 6 of the bed frame.
- the bed frame 4 is supported, in the vicinity of its two transverse sides 7, by two articulated structures of support 10 each comprising two legs 11, 12 which are cross in X and which extend substantially in planes vertical parallel to the transverse sides of the frame, these two legs being connected to each other by a pivot 13 at level of their crossing.
- this spacer ring 13a maintains for example a gap greater than 2 cm between the legs 11, 12, so as to prevent a user, especially a child, is not injured by displacement in scissor legs 11, 12 when the bed passes from its raised position to its lowered position or vice versa.
- the two legs 11 belonging respectively to two articulated support structures extend respectively between on the one hand the upper ends which are articulated on fixed pivots 14 integral with the first longitudinal side 5 of the bed frame, and on the other hand lower ends which are connected to each other by a longitudinal cross 15, supported by two of casters 2 and integral with a pedal 16 which extends towards outside the bed.
- this pedal 16 When the bed is in the lowered position, this pedal 16 has an upper surface which is accessible at the foot of a user and who is at a low height above ground, for example at a lower height 10 cm and preferably less than 5 cm, so only after removing the Murphy bed 1 from its position stowed under the fixed bed 3 by pulling on the outer handle 29, the user can hold the fold-away bed 1 exactly in the desired position while maintaining his foot depressed on pedal 16 while he is raising the foldaway bed in the raised position.
- the pedal 16 presses lightly on the floor when the bed is in the raised position, without lifting the rollers 2 secured to the cross member 15.
- the Murphy bed 1 is then immobilized, and on the other hand, the pedal 16 increases the stability of the bed retractable by providing an additional support point.
- the legs 12 belonging respectively to the two articulated support structures 10 extend respectively on the one hand between upper extremities which are each secured to a pivot 17 which can slide parallel to the transverse sides 7 of the frame bed, and on the other hand the lower ends which are connected to each other by a cross member 18 mounted on two casters 2.
- each articulated support structure 10 presents a gas spring 23 which, in the example considered, is mounted on the one hand between the aforementioned pivot 14 and on the other hand an additional pivot 24 which is fixed to the corresponding leg 12 between pivot 13 and end lower of said leg 12.
- the gas struts 23 can act with sufficient leverage to stress effectively the bed frame up by providing some assistance to the user.
- the latches 25 are in the form of two vertical metal plates which revolve around a axis of rotation 27 on supports 26 integral with the second longitudinal side 6 of the bed frame.
- latches 25 are connected to each other by a metal conjugation bar 28 which is integral at least one actuation handle.
- Each of the latches 25 extends longitudinally towards inside the bed frame, from the axis of rotation 27 up to a free end 30, in the immediate vicinity of a side walls of the corresponding yoke 20.
- a tension spring 31 is mounted between each yoke 20 and the corresponding lock 25, so as to upwardly urge the free end 30 of said lock, thus making this lock cooperate with a portion of the corresponding pivot 17, which protrudes out of the light 19 disposed opposite the lock 25.
- the lock 25 then remains in permanent contact with the pivot 17 by means of a support finger 33 which axially extends the lower edge of this lock.
- the lock then maintains the pivot 17 in the vicinity from its second stop position 22, with a certain play of sliding between said second stop position and a stop edge 34 formed at the free end of the lock.
- This stop edge forms a notch which is oriented towards pivot 17 and which on the one hand has a central contact zone 35 against which comes to bear the pivot 17 when the frame is in the raised position and is loaded, and on the other hand a protruding part 36 which is disposed between the contact area 35 and the upper edge 32 of the lock.
- the protruding part 36 projects towards the second stop position 22 from the contact zone 35, enough to cooperate with the pivot 17 by preventing the latch 25 to pivot to its erased position when this pivot 17 rests on contact zone 35.
