Description

The present invention relates to a bed, including a hospital bed for the treatment of patients at home.

It relates more particularly to a bed comprising at least one bed base having a receiving surface of a mattress, said sleeping surface, and at least four fall protection barrier elements positionable around the bedding surface of the bed base and couplable to said bed base.

Such beds are well known to those skilled in the art. Until now, such beds are generally equipped with protective barrier elements permanently fixed on the bed base. These protection elements are either retractable or movably mounted between an active position and an inactive position in which they extend under the bed base, to allow the bedridden person 15 to access or leave the bed, or to the nursing staff. to intervene on the said person.

This results in a complexity of the protection element itself or its connection to the bed. In addition, as these protective elements are intended to be permanently installed, the weight of the bed is high and the assembly / disassembly of protective barrier elements tedious.

Generally, such fall protection barrier members are formed of a plurality of bars, so that the weight of each barrier member is high, increasing the total weight of the bed.

An object of the present invention is therefore to provide a bed whose design 30 allows assembly / disassembly in a short time and easy way of the bed, in particular to facilitate its transport.

Another object of the present invention is to provide a bed whose design allows easy maintenance and a reduction in the number of types of parts to be stored.

Another object of the present invention is to provide a bed whose design allows a weight reduction of the bed.

For this purpose, the subject of the invention is a bed, in particular a hospitalized bed for the treatment of patients at home, said bed comprising at least one bed base comprising a mattress receiving surface, referred to as a sleeping surface, and least four fall protection barrier elements positionable around the bed base sleeping surface, and couplable to said bed base, characterized in that the fall protection barrier elements, or at least two of the fall protection barrier elements, of the bed are interchangeable fall protection barrier members, and in that the coupling means between each interchangeable fall protection barrier member and the mattress are means for releasably coupling said fall protection barrier member to said bed frame. In other words, the bed comprises at least four, preferably at least six, fall protection barrier elements, at least two, preferably at least four of said fall barrier protection elements, being interchangeable elements, that is, can be put in place of one another.

These at least two interchangeable anti-fall barrier elements of the bed are each coupled or releasably connectable to said bed base. The coupling means between the fall protection barrier element and the bed base are thus configured to releasably couple each interchangeable fall protection barrier element to said bed base. Generally, the bed base comprises a frame surrounding or delimiting the sleeping surface of the bed base and the fall protection barrier elements are couplable or coupled to said bed frame. The elements of the fall protection barrier are therefore integral with the bed base, in the state coupled to said bed base.

Preferably, the bed comprises at least six anti-fall protection barrier elements of which at least two, preferably at least four, are interchangeable.

More preferably, the bed comprises, among the interchangeable fall protection barrier elements, backrest function elements, referred to as backsplash and headrest, respectively positionable at the ends of the bed base and elements with a part delimiting function. lateral wall of the bed positionable along a side of said bed base.

Preferably, at least one of the interchangeable fall protection barrier members is interchangeable with an opposing positionally opposable fall protection barrier member, i.e., facing the sleeping surface. , so that the two barrier elements are facing the state coupled to the bed base. This interchangeability makes it possible to eliminate the notions left and right or head and foot at the level of the barrier elements. 25

Generally, at least a portion of the coupling means between interchangeable fall protection barrier member and box spring are the same or the same from one interchangeable fall protection barrier member to another, to allow interchangeability. Preferably, at least one of the fall protection barrier elements comprises a frame and at least one at least partial filling element of said frame, said or at least one of the at least partial filling elements of said frame being preferably, a flexible element.

The invention therefore also relates to a bed comprising at least one bed base comprising a receiving surface of a mattress, said sleeping surface, and fall protection barrier elements positionable around the bedding surface of the bed base and coupled to said protective base, at least one of the fall protection barrier elements comprising a frame and at least one at least partial filling element of said frame, said at least one at least one filling element of said frame being a flexible element.

This results in lightening of the bed due to the nature of the at least partial filling element of the frame.

Preferably, said at least one at least partial filling element of said frame is removably mounted on said frame.

Generally, said at least one at least partial filler element of said frame being a flexible element, the fall protection barrier element is equipped with means for tensioning and maintaining in the stretched state of said flexible element.

In particular, the frame of the fall protection barrier element is formed of at least two uprights and two crosspieces, one of the uprights, or respectively one of the sleepers, being mounted with variable spacing of the upright, or respectively of the crossbar, facing to form a frame of variable size, the amount, or the crossbar, mounted variable spacing, called voltage bar, forming at least a portion of the tensioning means and maintenance to the taut state of said flexible member. Advantageously, the at least partial filling element of said frame is formed by means of at least one textile panel or strip, at least one of the edges of the panel or strip being coupled to the bar Of voltage.

Preferably, the at least partial filling element of the frame is in the form of a strip of textile material wrapped around the elements, namely uprights or crosspieces, mounted with variable spacing of said frame, said strip being provided along two its opposite edges of rushes, the edges of the band equipped with rushes being coupled, overlap, to the tension bar, with the rods extending on either side of said tension bar, and substantially parallel to two opposite faces of the tension bar to come one in bearing contact with one of the faces, the other in bearing contact with the other of the faces of the tension bar according to the direction of 15 displacement of the tension bar, said faces of the tension bar being faces transverse to the direction of movement of the bar in the direction of a reduction or enlargement of said frame.

This arrangement ensures a tension of the strip over its entire width 20 through the combination of the rod and a face of the tension bar during the displacement of said tension bar.

This results in a homogeneous tension of the band without affecting the ease of disassembly of the filling element. Preferably, the bed comprises means for locking the at least partial filling element of the frame in the coupled state of said element to the frame tension bar.

As mentioned above, the bed 1, object of the invention, is more particularly a hospital bed for the treatment of home patients. However, the invention applies to any type of bed.

This bed comprises at least a bed base 2 having a receiving surface of a mattress, said coating surface 3, and at least four elements 4, 5 of 20 fall protection barrier positioned around the sleeping surface 3 of the bed base 2 , and couplable to said bed base 2.

In the examples shown, the bed 2 of the bed 1 is formed of a frame surrounding the mattress receiving surface 3 and the elements 4, 5 of the fall protection barrier 25 are intended to be fixed to said frame.

These fall protection barrier elements extend, in erect position, around the coating surface 3 of the bed base 2 and define an open or closed perimeter around said coating surface 3. This bed may also include a device 14 for driving up and down the bed frame shown here by a lifting device of the chisel type.

In a manner characteristically to the invention, the elements 4, 5 of the fall protection barrier, or at least two of the elements 4 of the fall protection barrier, of the bed are interchangeable anti-fall protection barrier elements, and the means 6, 7 coupling between each element 4 of interchangeable fall protection barrier and the bed base 2 are detachably coupling means of said element 4 of fall protection barrier to said bed base 2.

In the examples shown, the bed 1 comprises six fall protection barrier elements of which at least four are interchangeable.

In particular, the bed comprises, in Figure 1, two types of fall protection barrier elements which are distinguished essentially by the length of the barrier formed by said element.

There are four long-range fall protection barrier elements that are interchangeable with one another.

The short fall protection barrier elements are two in number and interchangeable with one another.

The long-term fall protection barrier elements are, for two of them, positioned at the ends of the bed base and form one headrest, the other the footrest of the bed, while the other two are positioned. on either side of the bed each along a side of the bed in the vicinity of the backsplash head.

The shorter fall protection barrier members are positioned on either side of the bed, each along a side of the bed in the vicinity of the footboard of the bed.

It is usually these small fall protection barrier elements that are removed for access or exit from the bed.

In the example shown in Figure 2, the fall protection barrier elements are six in number and are interchangeable with each other. Again, the bed 1 comprises among the elements 4 of interchangeable fall protection barrier, backrest function elements, called backsplash and backrest head, respectively positionable at the ends of the bed 2 and delimiting function elements of a part lateral wall of the bed.

To allow interchangeability, at least a portion of the coupling means 6, 7 between element 4 of interchangeable fall protection barrier and bed base 2 are identical or similar of a member 4 of fall protection barrier interchangeable with another.

In the examples shown, the means 6, 7 for coupling between an interchangeable anti-fall protection barrier member 4 and the bed base 2 comprise at least two substantially parallel legs 6 or uprights, 20 fitted to the barrier element 4 and projecting from the base of said barrier element 4 and two bases 7 carried by said bed base 2, each base 7 having a cavity 8 within which a leg 6 of the interchangeable anti-fall protection barrier element 4 is adapted to be introduced, Preferably by simple interlocking, the cavity 8 of each base 7 being an axial cavity, of vertical axis orthogonal to the coating surface 3, in the horizontal state of said surface 3 of coating.

It may be envisaged to equip the bed base with at least one additional base to allow said additional base to form, with a base of a pair of base plates of the bed base, an additional pair of bases adapted to receive an element. a fall protection barrier of a type different from the type of barrier elements of i0 fall protection coupled to the pair of bases pre-equipping the bed base.

In the examples shown in FIGS. 1 and 2, each base has the shape of a block provided with a cavity 8, this block being fixed to the frame of the bed base with the opening of its cavity positioned on the face of the top of said block. the horizontal state of the bedding surface 3 of the bed base.

The coupling means between the fall protection barrier element and the bed base are thus configured to allow coupling by simply moving the fall protection barrier element in a vertical plane towards the bed base in the positioned state of the element. fall protection barrier above said bed base. This results in a simplicity of assembly and disassembly.

To complete the coupling, the bed comprises means 9 for locking each element 4 of interchangeable fall protection barrier in the state coupled to the bed base 2.

In the examples shown, said locking means 9 are carried by each base 7 and are in the form of clamping means holding a leg 6 inside the cavity 8 of said base 7, these holding means preferably affecting the shape of a cam pivot lever whose cam is adapted to make more or less projection inside the cavity of the base according to the angular position occupied by said lever. Thus, as illustrated in FIGS. 5 to 7, each lever associated with a base is mounted to pivot about an axis, said horizontal, perpendicular to the longitudinal axis of the cavity 8 of the base. The cam of this lever comes, during the drive in angular displacement of the lever from the unlocked position to the locked position, resting on a deformable piece which tends to deform in the direction of a projection inside. of the cavity of the base to come to exert a support on the leg housed inside the 2974989 II cavity of the base. This deformation of the part is particularly visible in FIG.

This support between leg and deformable part allows the retention by friction of the leg inside the cavity of the base.

Unlocking is effected by angular displacement of the lever in an opposite direction. It is then sufficient to lift the fall protection barrier element to allow the legs of said barrier element to be extracted from the cavities of the bases. The coupling and uncoupling operation takes only a few seconds.

Since the coupling means between the fall protection barrier element and the bed base fitted to the fall protection barrier element 15 are arranged in the plane of said fall protection barrier element, it is easy to store said protective barrier element. fall arrest in the uncoupled state of the bed base by stacking or juxtaposition of said fall protection barrier elements. These fall protection barrier elements can be, in the uncoupled state of the bed base and during the transport phase of the bed, stored inside a bag and during the use phase of the bed, stored at the state juxtaposed at one end of the bed during the steps of entering or leaving the bed.

As mentioned above, at least one of the fall protection barrier elements comprises a frame and at least one at least one fill element of said frame. This at least partial filling element of said frame may be formed of bars or other.

In the preferred embodiment shown in the figures, said at least one element 11 for at least partial filling of the frame 10 is a flexible element.

Preferably, said at least one at least partial filling element 11 of said frame 10 is removably mounted on said frame 10.

As said at least one element 11 for filling at least part of said frame 10 is a flexible element, the element 4 of the fall protection barrier is equipped with means 12 for tensioning and maintaining the stretched state of said flexible element.

In the examples shown, the frame 10 of the element 4 of the fall protection barrier is formed of at least two uprights 101 and two crosspieces 102, one of the uprights, or respectively one of the crosspieces, being mounted at a distance variable amount of the amount, or respectively of the cross, facing to form a frame 10 of variable size, the amount or the crossbar mounted variable gauge, called tension bar 121, forming at least a portion of the means 12 for tensioning and maintaining the stretched state of said flexible element.

This tension bar 121 extends parallel to a stationary cross member 102A housed inside the frame and is connected to this stationary cross member by means of slides and a screw 124 allowing its rotation to vary the dimensions of the frame by varying the distance between cross members of the frame.

This spacing of the tension bar 121 from the stationary cross member of the frame 25 is limited by a limit stop 15 carried by a frame upright.

In the examples shown, the frame comprises two main uprights and two main crosspieces, one of which is movable to form the tension bar 121 of the frame. This frame is, moreover, compartmentalized by means of two intermediate uprights between which the filling element is arranged, the space left free between intermediate uprights and main uprights of the frame forming a gripping space of the element of protective barrier 10 fall arrest.

This frame has a stationary inner cross member 102A to which the tension bar 121 is connected at least via a screw 124, as described above.

The at least partial filling element 11 of said frame 10 is formed by means of at least one panel or strip of textile material, at least one of the edges of the panel or strip being coupled to the bar 121 Of voltage. In the examples shown, the textile web is wrapped around the stationary upper cross member 102 and the tension bar 121 of the frame 10, and the two edges of the web are coupled to the tension bar 121.

Said band 110 is provided along its opposite edges of rods 111, the edges of the band 110 equipped with rods 111 being coupled, overlapping, to the tension bar 121, with the rods 111 extending from both sides. the other of said tension bar 121, and substantially parallel to two opposite faces 122 of the tension bar 121 for coming one into bearing contact with one of the faces 122, the other in contact with each other. support with the other of the faces 122 of the tension bar 121, said faces 122 of the tension bar 121 being faces transverse to the direction of movement of the bar 121 in the direction of reduction or enlargement of said frame 10.

Of course, other embodiments could have been envisaged. It could thus have been chosen to couple one edge of the strip to the tension bar and the other edge of the strip to the stationary crossbar. It could also have been chosen to couple the two edges of the strip to the tension bar by inserting each ring of one edge of the strip into a longitudinal groove of the tension bar. 13 The solution chosen, namely to premont at least two rivets or pads 123 on the tension bar and to provide at least two holes in each longitudinal edge of the strip to fix each edge of the strip to the tension bar insertion with play the rivet of the tension bar in a hole of the strip, is an easy solution to implement. In addition, the disassembly of the band operates easily.

In this position, in which the strip is fixed to the tension bar, as represented for example in FIG. 8A, the edges of the strip overlap and the rods equipping said edges extend on either side of said strip. 121 tension bar and substantially parallel to two opposite faces 122 of the tension bar 121, to come one in bearing contact with one of the faces 122, the other in bearing contact with the other the faces 122 of the tension bar 121, as a function of the direction of movement of the tension bar 121, said faces 122 being faces transverse to the direction of movement of the bar 121 in the direction of a reduction or a enlargement of said frame.

In order to maintain the position of the strip, the bed comprises means 13 for locking the at least partial filling element 11 of the frame 10 in the coupled state of said element to the tension bar 121 of the frame 10.

In the examples shown, these locking means 13 affect the shape of a bar 131 positionable bearing on the tension bar 121. This locking bar 131 is provided on the face intended to bear on the tension bar 121, housing, such as grooves 132 adapted to house the heads of the organs, such as studs or rivets, help fixing the strip to the tension bar 121.

In the fixed state of the locking bar 131 to the tension bar 121, the disassembly of the constituent band of the filler element is impossible. The operating principle of such an assembly is as follows, as illustrated in FIGS. 8A, 8B, 9 and 10.

At first, the web is wrapped around the top rail and the frame tension bar, and is attached to the tension bar as explained above.

The locking bar 131 disposed parallel to the tension bar is then slidably displaced in a vertical plane towards the tension bar, as shown in Fig. 8A, or in a horizontal plane along the tension bar for allow the insertion of the studs or rivets in the slots of the locking bar.

The tension bar is then moved in the direction of web tension, i.e. enlargement of the frame with screw 124. This movement of the tension bar causes progressive tension of the band with a slight slippage of the band during this tension, so that the rods of the band tend to want to be positioned between the tension bar and the locking bar.

This effort of the rods tends to move the locking bar of the tension bar reinforcing the frictional forces between the locking bar and studs at the head of said pads, so that the locking is reinforced.

For unlocking, it is necessary to proceed in the opposite way, that is to say to relax the band and then to remove the locking bar before disassembling the strip of the tension bar.
