Description

Technical area

The invention relates to a new changing table of the type comprising a tray suitable for receiving a changing mat.

Previous techniques

We already know changing plans intended to be adapted on top an opening, such as above a bathtub or a cot, in which the underside of the tray intended to receive the changing mat proper, has studs capable of wedging the plate on the edges of the opening. Although widely used, this solution has the disadvantage of be adapted to only one opening width. It follows an absence of versatility according to the different opening dimensions, and therefore a lack of safety in the conditions of use where the opening is different from that for which the plan is planned. Indeed, a changing table adapted to a bathtub determined cannot adapt to a cot and vice versa (see also BE-A-896 888 and EP-A-0288047).

The invention overcomes these drawbacks. It aims at a changing plan of the type in question which is perfectly adapted whatever the dimensions of the opening of the organ intended to receive it.

Brief description of the invention

The invention relates to a changing table comprising a tray capable of receiving a changing mat, intended to be fitted on top of an opening, in particular the top of a bathtub or a cage bed, and in which the underside of the plate has means capable of wedging said plate on the edges of the opening, characterized in that these means are adjustable in position and lockable on the edges of the opening.

In a first embodiment, the plate has on both main lateral edges of the longitudinal recesses intended to form tanks for storage.

In a second preferred embodiment, the plate is shaped general rectangular, and according to the invention said tray has lights arranged in a cross in the vicinity of each of its four angles and the means of adjustment and locking features are able to slide and lock in said lights.

Way of realizing the invention

Referring to Figure 1, the changing plan according to the invention designated by the general reference (1) is made by thermoforming in plastic material polyolefin, such as polypropylene or polyethylene.

This changing table (1) includes a tray (2) capable of receiving a mattress changing not shown, commonly used for this application. This changing table is intended to be fitted on top of an opening, such as the edges of a bathtub (B1, B2) or a cage bed (L1, L2).

The plate (2) has on the two main lateral edges (3,4) recesses (5,6) intended to form storage bins for various objects, such like sponges, brushes, soaps, etc.

In the preferred embodiment, the plate (2) is of general shape rectangular and has four lights at each of its four angles (10,11,12,13). More precisely, the underside of the tray (see Figure 2) has two reinforcing ribs (15,16) in X, the ends of which have said lights (10-13). These lights (10-13) cooperate with a means of adjustment and locking characteristic of the invention.

• un plot (21) creux moulé ou thermoformé formant pied, de forme générale légèrement tronconique, et dont le fond (22) d'une part, vient s'appliquer contre la face inférieure (19) du plateau (2), et d'autre part, présente deux oreilles (23,24) disposées sur le dessus (voir figure 5), destinées à être positionnées contre les bords des rainures (15) et (16); la face interne du fond (22 ) présente une couronne cylindrique (25) dont les parois sont sensiblement parallèles à celles du plot (21), mais dont la hauteur est limitée seulement à une portion du fond ;
• un taquet coïnceur (30) également en matière plastique moulée ou injectée, monobloc, constitué respectivement
  • d'une base (31) destinée à venir se loger dans la couronne (25) en s'appuyant sur la face interne (26) du plot, d'un bras (32) orthogonal à la base (31) destiné à traverser et à coulisser dans les lumières (10-13);
  • d'un axe (33) parallèle à la base (31), destiné à passer à travers l'ouverture caractéristique (27,28) ménagée sur le dessus (22), puis à dépasser les lumières (10-13);
  • d'un joint torique (34) compressible, destiné à être interposé entre la face supérieure (35) de la base (31) et la face inférieure (26) du fond de la couronne (25);
• une languette de blocage (40) (voir figures 6, 7 et 8), constituée d'un levier (41) présentant à une extrémité un crochet (42) formant came destiné à s'engager dans l'axe (34); en basculant le levier (41) (voir figure 7), on comprime le joint torique (33) grâce au déplacement de la came (42) qui réhausse l'axe (33) du fait de l'escamotage du levier (41) (voir figure 7).

This characteristic means (see FIGS. 6, 7 and 8), designated by the general reference (20), is essentially formed by three distinct parts, namely respectively:

• a hollow molded or thermoformed stud (21) forming a foot, of generally slightly frustoconical shape, and the bottom (22) of which, on the one hand, is applied against the underside (19) of the plate (2), and on the other hand, has two ears (23,24) arranged on the top (see Figure 5), intended to be positioned against the edges of the grooves (15) and (16); the inner face of the bottom (22) has a cylindrical crown (25) whose walls are substantially parallel to those of the stud (21), but whose height is limited only to a portion of the bottom;
• a coincidenting cleat (30) also in molded or injected plastic material, in one piece, constituted respectively
  • a base (31) intended to be housed in the crown (25) based on the internal face (26) of the stud, an arm (32) orthogonal to the base (31) intended to pass through and to slide in the lights (10-13);
  • an axis (33) parallel to the base (31), intended to pass through the characteristic opening (27,28) formed on the top (22), then to exceed the openings (10-13);
  • a compressible O-ring (34), intended to be interposed between the upper face (35) of the base (31) and the lower face (26) of the bottom of the crown (25);
• a locking tab (40) (see Figures 6, 7 and 8), consisting of a lever (41) having at one end a hook (42) forming a cam intended to engage in the axis (34); by tilting the lever (41) (see FIG. 7), the O-ring (33) is compressed by virtue of the displacement of the cam (42) which raises the axis (33) due to the retraction of the lever (41) ( see figure 7).

When the user wishes to adjust the changing table on the opening of a cot or a bathtub, just remove the changing mat to gain access to the cleats (30) and to slide the arm (31) into the lights concerned until the stud (21) comes to rest on the edges concerned. At the moment, conventionally, the user folds the lever (41) of the tongue (40) to ensure the positioning and locking of the studs (21) against the edges of the opening concerned. In the locked position (see Figure 7), the tab (41) is completely retracted into the ribs (15,16) so as not to form protrusion on the back of the changing mat.

Advantageously, the stud (21) has a lateral lug (50) orthogonal to the plan of the stud, intended to serve as a stop to pass under the upper crosspieces of a cot and thus ensure good maintenance of the changing table.

In an advantageous version (see Figure 3), the rear side face vertical of the changing table has openings intended to receive suction cups (60) which are intended to be pressed against the vertical wall generally tiled overhanging the bath, and thereby ensuring good support from the whole.

• la simplicité mécanique ;
• la parfaite adaptation aux différentes dimensions des ouvertures possibles ;
• la versatilité d'adaptation ;
• la sécurité d'emploi.

The changing table according to the invention has many advantages over those used to date. We can cite :

• mechanical simplicity;
• perfect adaptation to the different dimensions of the possible openings;
• versatility of adaptation;
• job security.

In this way, it can be successfully used in all applications of changing plans.
