Drawer-sommier

Abstract: The Drawer-sommier is another way of making a bed with regard to the former technique, using wood without making use of iron to achieve the traditional small board grill sommier firmness (2), and ussing wooden crossbars (3) sufficiently high to hold the weight of the persons. This allows for the framework (1) to be closed with a timber board at the bottom that provides an air chamber (5) between the closed bottom (4) and the mattress.

Description: The invention relates to a bed frame for supporting a mattress composed of a wooden framework having opposite sides of wood that can be assembled with wooden corner pieces at the corners of the frame, a small-board grill resting uppon wooden crossbars which are linked to both opposite sides of the framework and a closed bottom of timber board being jointed to the crossbars and the framework which produces an inside cavity or air chamber between the closed bottom and the mattress supported on the small-board grill. The prior art refers to traditional wooden cabinet-type bed frames for supporting bed springs composed of a metal grill fixed to a frame also metallic that in turn support mattresses. It has also been proposed a small-board grill, yielding with the weigth, fixed to an iron framed then iron bars are used with the small-board grill, underneath, to keep it rigid. The use of synthetic materials has been proposed in frames that are designed to support the mattress. In the case of a day bed there is no small-board grill but rather a frame is provided that is generally covered with cloth and includes a base adjacent the floor. Also it has been proposed to provide a metal frame that is covered with cloth and has the shape of a box-like frame for supporting bed springs, the inside cavity of the box-like frame serving as a wardrobe. Document FR-A-2 547 185 discloses a bed frame according to the preamble of claim 1. While having these and other configurations wooden bed frames for supporting mattresses have the sole function (with regard to that directly influence the human body) being the support of bed springs which support mattresses, pointing at its style or design as the most relevant features.The invention seeks to provide a more convinient set to rest and to sleep in accordance with the wooden industry. The Drawer-sommier is something more than mere support for the mattress. It has evolved from a plane form as a bed spring without volume to another form with volume in the shape of a drawer in which appears an inside cavity. The invention seeks to provide an air chamber producing insulation within said wooden structure. Iron is a conductor of electricity electromagnetic and sound waves, as well as a thermal conductor and it is contrary to the main object of the invention which is insulation. Otherwise wood is insulating. Another object of the invention is to provide a bed frame for supporting a mattress which eliminates the need of a bed spring. Accordingly, the invention seeks to provide a breathable surface receiving the mattress that allows different configurations. In one embodyment the small-board grill is placed in downwardly-spaced relation relative to the upper edge of the framework. In this case the mattress remains fixed surrounded by a portion of the framework avoiding that the mattress moves to the sides. Another embodiment provides a small-board grill with independent flexible small boards susceptible of substitution then supplementary small boards are provided to create a surface with different contours. A further embodiment provides a small-board grill made of small boards fixed to opposite support slats supported by the opposite sides of the framework, supporting the mattress either adjacent or in downwardly-spaced relation relative to the upper edge of the framework. In accordance with the invention the insulation, produced by the air chamber, keeps the mattress from the draft, the temperature changes and the humidity, keeping the warmth of the body. It also keeps the mattress from the dust considerably. The rigidity of the bed set supplies a straight position for the human body when resting, due to the stabilizing wooden crossbars which keep the small-board grill firm. The wooden framework with corners externally rounded appears beautiful and avoids bumping one's body. The comfort added to the body by the air chamber makes unnecessary the use of voluminous mattress. The invention is particularly conceived to be used in a raised-spaced relation relative to the floor, to keep the effect of the air chamber, that allows connecting different interchangeable support components as: bed legs, bed wheels, a skirting board or to be fitted to bed backs. The assembly of the corner pieces to the frame can be made by mortise and tenon joint method, generally use in cabinet work, with the possibilty to mount or to dismount the framework, which union can be improved with a reinforcement bracket of wood or metal. The wooden crossbars can be assembled to the framework also with the possibility to mount or to dismount them. The small-board grill can be made of independent small boards which rest uppon the wooden crossbars, their flexibility allows for these to be inserted in the side slots of the framework, they are fixed downwards forming the firm support of the mattress. The bottom is made of timber board and it is fixed to the framework by a rebating glued or screwed, which would reinforce the solidity of the bed set. Fig. 1 shows the drawer-sommier with comer pieces externally rounded for embedded mattress, and independent small-boards. Fig. 2 shows a) the drawer-sommier without comer pieces for embedded mattress, and b) the drawer-sommier for mattress on the surface with a fixed small-board grill. Fig. 3 shows a) the drawer-sommier with legs for embedded mattress and a detail of independent small board and b) the drawer-sommier with legs for embedded mattress and a detail of independent small-board grill. Fig. 4 is a cross section of the drawer-sommier for embedded mattress: a) independent small boards, b) fixed small-board grill, c) independent small-board grill. Fig. 5 is a cross section of the drawer-sommier for mattress on the surface: d) fixed small-board grill, e) independent small-board grill. Fig. 6 shows a) type of the drawer-sommier, b) side view, c) use, d) side view of the small-board grill and independent small board 9, e) side view of the small-board grill and suplementary small board 7. Fig. 7 is a cross section of the ancorage device 8; the left-hand side: head board; the right-hand side: drawer-sommier. Fig. 8 shows a way of assembly: comer piece 6, slot 10, metal bracket 18. Fig. 9 shows the invention to be used with different support components: bed legs 12 or bed wheels 13, with capacity for two mattresses 17, a skirting board 14, a head board 15 or to be fitted to bed backs 16. While the preferred forms and embodiments have been illustrated and described, it will be apparent to those skilled in the art that various changes may be made without deviating from the inventive concepts set forth above. Accordingly, the assembly method to connect the different parts of the frame with its correspondent corner section sides, may vary, in accordance with the preferences of the manufacturers, since there are found several devices in the market that make possible its connection. The measurements of the drawer-sommier may vary in accordance with the use, as is the case to adapt them for a cradle. The invention can be standard manufactured, due to its uniform parts, just as metallic springs are made at independent factories, becoming an essential tool for those furniture manufacturers that work only with wood, reducing work and time.
