Description

The invention relates to the field of foldable beds, and in particular foldable medical beds.

• des roulettes pour permettre au lit d'être déplacé notamment lorsque le patient est dessus ;
• un sommier dont le dossier est relevable ;
• un système de réglage en hauteur du sommier ;
• une tête et un pied de lit ;
• des éléments permettant l'accrochage de divers accessoires tels que des tables, des barrières ou encore des potences.

Patients with movement-limiting illness require special home care and, as such, require the use of appropriate medical equipment for their comfort. This material is very often bulky because it must incorporate many features to help the patient. In the case of medical beds, the beds most often include:

• rollers to allow the bed to be moved especially when the patient is on it;
• a sommier whose backrest is liftable;
• a system for adjusting the height of the bed base;
• a head and a footboard;
• elements allowing the attachment of various accessories such as tables, barriers or even gallows.

The constitution of the bed also depends on the needs of the patient. The bed is made especially for these needs, then it is transported to the patient where it is installed.

Transport, given the size of the bed, is a step that poses a problem. Indeed, the dimensions of the beds thus formed are not suitable for places other than hospitals or other specialized institutions. Various solutions have been considered to solve this problem.

A first solution is to place the bed, complete or in a pre-assembled position, on a support, usually provided with wheels. The bed is placed at an angle, so as to allow its passage more easily.

A second solution is to transport the bed in spare parts on the support. This second solution offers the advantage of providing a more compact package for transportation. However, an additional assembly step is necessary, which assembly can be tedious when the number of elements of the bed is important.

The support used to transport the bed is specific. In other words, this support can not be used for beds of different structures. Providers of beds, so as not to have to store any a range of supports, so manufacture each support according to the bed to be transported and get rid of the support once used.

Installers bringing a bed to a person must bring support and then take it away once the bed is installed, which can be tedious.

Some manufacturers have developed folding medical beds, which allow the bed to be transported in a folded position to reduce congestion, without using bed transport support, and then mounting the bed to the patient. The assembly of the bed is by unfolding and blocking in the unfolded position.

The document EP 1 658 787 , for example, discloses a bed in two parts pivoting relative to each other between an extended position in which the two parts form an angle of 180 ° and a folded position, more compact in which the two parts are folded l one to the other.

However, the beds thus formed do not allow a great variation of the equipment, the folding mechanism limiting the space around the bed base. Accessories that may be needed with the bed must be brought separately from the bed.

In addition known medical beds in kit, in which the bed is in parts, a bed element, usually the base, serving as a carrier. When the bed is to be brought to a person, no element outside the bed is brought.

For example, the document FR 97 13188 describes a bed, comprising two parts on wheels, of substantially identical sizes. The two parts are detachable, and can take a vertical position relative to the wheels or a horizontal position. Therefore, the two parts are placed in a vertical position relative to the wheels, and then are fixed against each other, the assembly being able to roll to be moved. To assemble the bed, the two parts are separated, and they are placed in a horizontal position on the wheels. By tilting each part relative to the other, they are hooked to each other, forming the bed.

The document US 5,438,723 has a bed, in which the bed base and the base are in three detachable parts: a foot part, a head part and a sitting part. The base is assembled in a compact position, in which its seating part is placed between the head and foot parts, the latter two being placed perpendicular to the first. Wheels are fixed under the seat part, so as to form a mobile assembly. The parts of the bed base are reported on the whole. To form the bed, the different parts of the base and the bed frame and the wheels are detached. Then the different parts of the base are assembled, and the wheels are fixed on the parts head and feet. The parts of the bed frame are then positioned and fixed on the base.

One of the disadvantages of these kit beds is that they are difficult to assemble and disassemble for one person. Indeed, an imbalance is caused during the passage of the bed from its folded position to its position of use, both when fixing the two parts of the bed in the document FR 97 13188 only when moving the fixation of the wheels on the bed in the document US 5,438,723 .

The present invention aims in particular to remedy these problems.

A first object of the invention is to provide a bed structure adaptable to beds having various features.

A second object of the invention is to provide a transportable bed without elements external to the structure of the bed.

A third object of the invention is to minimize the size of the bed during the transport step.

A fourth object of the invention is to allow assembly and disassembly of the bed easily by one person.

A fifth object of the invention is to allow the use of wheels mounted on the bed both during transport once the bed is installed.

According to a first aspect, the invention provides a bed as claimed in claim 1.

The base thus formed can be folded and deployed in a single pivoting operation.

In the deployed position, the front and rear frames are preferably in contact with the ground, so as to form a stable assembly on the ground. The contact is made in particular by means of wheels, allowing the base to be easily moved.

The wheels of the front frame are distributed for example in two trains placed on either side of the axis of pivoting of the rear frame relative to the front frame. Thus, when the base is in the folded position, the weight of the rear frame is distributed over the two trains, bringing more stability to the assembly.

According to one embodiment, the bed comprises a holding device blocking the base in the deployed position, preventing the frames from moving relative to each other. The holding device comprises for example on the sections of longitudinal members of the rear frame, an oblong opening and slot extending in the direction of slenderness of the section, the notch being partially open, and the device comprises two axes carried by the sections of longitudinal members of the front frame, a pivot axis being inserted into the opening of the rear frame, and a holding pin coming into the notch by pivoting the rear frame in the extended position, the pivoting of the rear frame being prevented following the sliding both axes in their respective housing.

According to another embodiment, the bed comprises a locking device blocking the base in the folded position, for moving the folded base without inadvertently expanding.

Preferably, the sections of longitudinal members of the front frame are shorter than those of the rear frame, so that the floor space occupied by the base in the folded position is reduced.

According to a third aspect, the invention proposes a bed comprising a base as described above and a bed base, in which each part of the bed base comprises an armature in which is mounted a support element of a mattress, this element being articulated. relative to the frame between a plane position in which the element is in the plane of the frame and a raised position in which it forms an angle with the plane of the frame.

According to one embodiment, the height of the bed is adjustable, for example by means of a crossbar system, where each spider is placed between the front frame and the rear frame. According to one embodiment, a first bar of each spider is pivotally and slidably mounted on a spar section of the rear frame, and the second bar of the spider is pivotally mounted on the front frame, the two pivoting bars around parallel axes between them and parallel to the pivot axis of the two frames. In this way, when the base is in the folded position, the first bar of each spider is supported on the front frame, so as to maintain the base in the folded position and thus facilitate transport. In addition, when the base is in the folded position, the first bar braces can be fixed on the front frame, so as to permanently block the rotation of the rear frame relative to the front frame. The height can be adjusted by means of a column system.

According to a second aspect, the invention provides a bed transport kit, comprising a bed as described above, further comprising a bed frame, which comprises a front portion a rear portion, separated from one another and fixed on the base, so as not to have to use a transport support outside the bed to transport it.

The two parts of the bed base are preferably of substantially equal dimensions in order to best distribute the load on the folded base. This load distribution can also go through the fact that the two parts of the bed frame are fixed on either side of the rear frame. The parts of the bed base can also be fixed on the front frame of the base, so as not to rock the base during transport. A head and footboard can be attached to the base.

On the figure 1 there is shown a transport kit for a bed 1. The bed 1 comprises a base 2 and a bed base 3.

The base 2 comprises two longitudinal members 4, separated into two sections, so that the base comprises two articulated parts.

A first part of the base 2, called front frame 5, is supported on the ground. The front frame 5 comprises an armature 6 comprising two sections 7 of longitudinal members 4 and a cross member 8 connecting them. From the crosspiece 8, extend two longitudinal bars 9, parallel to the two sections 7, and connected by a parallel transverse bar and of shorter length to the crosspiece 8, so as to form a step on the frame 6. According to a preferred embodiment, the front frame 5 is in stable support on the ground. The stable support is achieved for example by means of two sets of wheels 11 and 12 fixed to the front frame 5. A first set of wheels 11 is fixed on the two sections 7 of the longitudinal members 4, and a second train 12 is fixed on the transverse bar 10 of the staging. The first gear 11 of wheels comprises for example two wheels fixed on the two sections 7 of longitudinal members 4, while the second gear 12 of wheels comprises one. The set then forms a stable support by three points of support.

A second part of the base 2, called a rear frame 13, also comprises two sections 14 of longitudinal members 4 connected by a cross member 15. A wheel train 16 is fixed on the rear frame 13.

The rear frame 13 is pivotally mounted on the front frame 5. For this purpose, the rear frame 13 comprises an opening 17, placed on each section 14, and in which is inserted a pivot pin 18 carried by each section 7 of longerons 4 front frame 5, these axes 18 being located between the two wheels 11 and 12.

The base 2 can then take two positions.

In a first position, said folded, the rear frame 13 is raised relative to the front frame 5 so that the sections 14 of longitudinal members 4 of the rear frame 13 form a substantially equal angle at 90 ° with the sections 7 of the front frame 5. In this position, the sections 7 of longitudinal members 4 of the front frame 5 extend on either side of the rear frame 13.

The base 2 passes into a second position, said deployed, by pivoting the rear frame 13 about the axis 18 of the front frame 5, wherein the sections 14 of the longitudinal members 4 of the rear frame 13 are in line with the portions 7 of the frame before 5.

According to a preferred embodiment, in the deployed position, the rear frame 13 is in contact on the ground, by means of the wheels of the train 16.

In addition, according to a preferred embodiment, the sections 7 of the front frame 5 are shorter than those 14 of the rear frame 13, so that the floor space occupied by the base 2 in the folded position is reduced.

The base 2 further comprises a device 19 for holding in the extended position, comprising a notch 20 carried by each section 14 of the rear frame 13 and a holding pin 21 carried by each section 7 of the front frame 5. The notch 20 has a oblong shape, extending in the direction of slenderness of the section 14, and an opening not extending all the way along the notch 20. Thus, a bottom of the notch 20 is closed. The notch 20 and the opening 17 are distributed longitudinally on the section 14. The retaining pin 21 is located on the sections 7 of the longitudinal members 4 of the front frame 5, between the wheels of the first gear 11 and the end of the sections. opposed to staging. The pivoting opening 17 also has an oblong shape, in the same direction as the notch 20. Consequently, the base 2 is brought into the extended position by pivoting the rear frame 13 and by inserting the axis 21 maintaining in the notch 20, the sections 7 and 14 of the longitudinal members 4 of the two frames 5 and 13 then being in the extension of each other. Then, the shafts 18 and 21 respectively for pivoting and holding respectively slide in the opening 17 and in the notch 20, so as to prevent any relative rotation of the frames 5 and 13 of the base 2.

In addition, the base 2 comprises a locking device in the folded position.

The bed base 3 of the bed 1 comprises two parts 30 and 31. Each part, respectively 30 and 31, comprises a frame, respectively 32 and 33, in the form of U, in which are fixed support elements of a mattress, such as slats, meshes, springs or plates. These elements can be articulated with respect to the frame, thus forming a lift-up backrest or an adjustable seat. The two parts 30 and 31 are independent of each other, so as to be separated in a disjoint position, or to be integral in an assembled position, these two positions being illustrated respectively on the figures 8 and 9 . According to one embodiment, the assembled position is obtained by interlocking and then by fixing the two frames 32 and 33 in the extension of one another, so as to form the bed base 3. For this purpose, the reinforcement 32 of a portion 30 of the bed base 3 comprises on its branches 34 a reduced section 35, which is inserted into a branch 36 of the frame 33 of the second part 31. Then, fastening elements such as screws are mounted between the two frames 32 and 33.

On the bed 1 disassembled as a transport kit, the base 2 is brought and locked in the folded position, and the two parts 30 and 31 of the mattress 3 in the disjoint position are fixed on the base 2 ( figure 1 ). The two parts 30 and 31 are fixed on the front frame 5, and preferably on either side of the rear frame 13, distributing the load on the front frame 5 so as to maintain equilibrium. The parts 30 and 31 of the bed base 3 are fixed for example by means of pins inserted between the base 2 and the frames 32 and 33. Other elements such as a head and a footboard or a bracket can also be fixed on the base 2 or on the bed base 3.

In order to move into the extended position of the base 2, the parts 30 and 31 of the bed base 3, as well as the other elements, are detached and removed from the base 2 in the folded position ( Figures 2 and 3 ). The locking device is removed, allowing the rear frame 13 to pivot relative to the front frame 5 ( figures 4 and 5 ), until the base 2 is in the deployed position and the holding device 19 is put in place ( figures 6 and 7 ). The base 2 then forms a set in stable equilibrium on the ground.

A first portion 30 of the bed base 3 is then placed on the deployed base 2, then the second portion 31 is brought to the base 2 so as to be engaged and fixed on the first portion 30 in the assembled position. The bed base 3 thus formed is then attached jointly and severally on the base 2, forming the bed 1 in the mounted position, the other elements can then be fixed on the bed 1, which is then in the mounted position.

The disassembly of the bed 1 and its transformation into a bed transport kit is carried out by carrying out the reverse operations: separation of the bed base 3 and the other elements of the base 2, the two parts 30 and 31 of the bed base 3 being placed in disjoint position, sliding frames 5 and 13 so as to bring out the axis 21 for holding the notch 20 and then pivoting the rear frame 13 in the folded position of the base 2, locking in the folded position and finally fixing the parts 30 and 31 of the bed base 3 and possibly other elements of the bed 1 on the base 2 or the bed base 3.

According to one embodiment, the bed 1 comprises a mechanism for adjusting the height of the bed base 3.

This mechanism is for example a column system, in which telescopic columns are integrated in the base 2 so as to change the height of the base 2 relative to the ground or the height of the bed base 3 relative to the base 2.

According to a preferred embodiment, and as illustrated on the Figures 10 to 13 , the adjustment mechanism comprises two braces 40, mounted between the two frames 5 and 13 of the base 2, the braces 40 being mounted and operating symmetrically.

A spider 40 has two bars 41 and 42, pivotally mounted relative to each other. A first bar 41 is mounted, by a lower end 43, pivoting and sliding on a section 14 of the rear frame 13, about an axis parallel to the axis 18 of pivoting frames 5 and 13. The lower end 44 of the second bar 42 is pivotally mounted on the front frame 5, about an axis parallel to the pivot axis 18. In practice, the lower end 44 of the second bar is fixed to the cross member of the front frame by means of a hinge 45.

In this embodiment, the braces 40 are used in the locking device of the base 2 in the folded position. Indeed, when the base 2 is in the folded position, the upper end 46 of the first bar 41 of the spider 40 is fixed on the front frame 5, preventing the rear frame 13 from pivoting. To this end, on each section 7 of longitudinal members 4 of the front frame 5, is fixed a gutter 47 on which bears the upper end 46 of the first bar 41. A pin is then inserted through the bar 41 and a section 7 of the front frame 5, solidarisant all. A portion 30 of the bed base 3 is then resting on the braces and the upper end 48 of the second bar 42 remains free.

To put the base 2 in the deployed position, the pin between the brace 40 and the front frame 5 is removed, leaving the rear frame 13 free to pivot until the base 2 arrives in the deployed position. In this position, the ends 46 and 48 of the upper two bars 41 and 42 of the spider 40 are free and coplanar. The bed base 3 can then be assembled and fixed on these ends 46 and 48 of the braces 40.

The height of the bed base 3 relative to the base 2 can be adjusted by varying the angle between the two bars 41 and 42 of the braces 40. For example, the second bars 42 of the braces 40 can be connected by a transverse bar. A piston 49 is mounted between the base 2 and this crossbar. The manual or electrical actuation of the piston 49 causes the pivoting of the bars 41 and 42 of the braces 40 and the sliding of the first bars 41 against the sections 14 of the longitudinal members 4 of the rear frame 13, so as to simultaneously vary the height of the ends 46. and 48 upper bars 41 and 42 of the braces 40.

The bed 1 thus described can be easily transported to the disassembled position thanks to the front frame 5 resting firmly on the floor on the rollers. It offers a compact form, adapted to the structure of the homes of individuals in which such a bed 1 must be installed. The size of the sections 14 of longitudinal members 4 of the rear frame 13 is chosen in order to correspond to the standards of homes of individuals.

In this position, it is also possible to report on the base 2 other elements such as a head or a footboard or even a bracket, and then fix them on the bed 1 once mounted, the number and shape reported elements not being limited by the design of the bed 1.

In addition, the steps of assembly and disassembly are easily done by one person because whatever the position of the base 2, it is in stable equilibrium on the ground, without having to resort to elements additional, and it moves from one position to another by a pivot.

Finally, the base 2 of the bed 1, in the folded position, serving as a transport medium, the bed 1 does not require to manufacture an additional element whose design depends on that of the bed 1.
