Abstract
Description
- The invention relates to a mattress base consisting of a rectangular frame, a plurality of slats disposed transversely at determined intervals, and spring members mounted between the ends of the slats and the longitudinal members of the frame.
- The invention relates more particularly to the spring members making the connection between the ends of the slats and the longitudinal members of the frame.
- SLatted mattress bases are a very practical and comfortable alternative to conventional spiral bed- springs and box springs. Not only do they provide zonal distribution of hardness, but also offer greater stiffness.
- The spring members by which the slats of a mattress base of this kind are connected to the longitudinal members have a great influence on the comfort of the bed. A stiff connection between the ends of the slats and the frame results in a hard, scarcely comfortable bed. Known spring members include rubber supports, which however have the disadvantage of Limited life, flexibility and compressibility.
- Leaf springs are a known alternative to rubber supports. These known Leaf springs, as described in NL 8402221 and NL 8400147, consist mainly of a strip folded in V-shape. They have the disadvantage that on the one hand the places where the strip is folded are weak spots in respect of strength and life, and that on the other hand the slats supported on the V-shaped leaf springs can make only a vertical movement.
- The aim of the mattress base according to the invention is to provide a bed which gives maximum comfort and which is built with constructionally simple and durable elements. The aim of the mattress base according to the invention is more particularly to increase the freedom of movement of the slats so that, while retaining maximum vertical yieldability, the slats can also tilt and undergo a certain horizontal displacement.
- The mattress bass according to the invention is characterized by spring members which consist of a leaf spring whose longitudinal axis is directed at right angles to the longitudinal axis of the slats, and whose shape consists substantially of three parts: a middle part which extends substantially horizontally and on which the ends of one or more slats are supported, and two side parts which form the ends of the Leaf spring and which, starting from the middle part, first extend downwards and then partly extend towards one another, whereupon they extend back upwards and are rigidly fastened by their ends against the longitudinal members of the frame.
- Further details of the mattress base according to the invention will emerge from the following description of one possible form of construction of the mattress base according to the invention, as an example not constituting a Limitation. This description is given with reference to the accompanying drawings, in which:
- Figure 1 is an elevation of the inner side of a longitudinal frame member, a spring member and its fastening to the longitudinal member being shown in front elevation and the slats in section.
- Figure 2 is a section, on the Line AA in Figure 1, of a longitudinal frame member, a spring element and its connection to the longitudinal member being shown in section and the slats being shown in longitudinal section.
- Figure 3 is a longitudinal section of the end of a slat and a connector.
- Figure 4 is a longitudinal section of the end of a slat and a connector with a buffer block.
- As illustrated in Figures 1 and 2, the slatted base according to the invention consists substantially of a frame, whose
longatudinal members 1 carry theslats 2 viaspring members 3. A spring member of this kind is made from a strip of metal and has a shape such that themiddle part 4, on which one ormore slats 2 are fastened, extends substantially horizontally and that starting from themiddle part 4 theends 5 first extend downwards and then, after extending towards each other over acertain distance 6, extend back upwards to pass into thefastener 7. Thefastener 7 is fastened by twostuds 8, each of which fits into a tapped hole in theLongitudinal member 1 of the frame, against the inner face of theLongitudinaL member 1. Thefastener 7 is provided with twogrooves 9. Theend 5 of aspring member 3 can be inserted over its entire width into agroove 9. To ensure optimum, rigid fastening between thespring member 3 and thefastener 7, eachend 5 is provided with ahook 10 and thegroove 9 is shaped accordingly. - In view of the fact that the width of the
middle part 4 is greater than the distance between the points where theends 5 pass out of thegroove 9 in thefastener 7, and because of the rigid connection between theends 5 and the fastener. 7, thespring member 3 can, through the action of the Load on theslats 2, not only make a vertical yielding movement but also make a tilting movement about thefastener 7 and undergo a certain horizontal displacement. In this way theslats 2 are given maximum freedom of movement, which results in increased comfort of the bed. On the other hand, thespring member 3 has no single weak point because of its rounded shape. The simple fastening between thefastener 7 and thelongitudinal member 1 enables the height of theslats 2 to be adjusted in a simple manner, in the state of rest, to the shape of the body. It is sufficient to fasten thestuds 8 of thefasteners 7 at a different height on thelongitudinal members 1 - The connection between a
slat 2 and thespring member 3 is achieved with the aid of aconnector 11, preferably made of plastics material (see Figures 1 and 2). Aconnector 11 of this kind consists substantially of achamber 12 embracing the end of aslat 2 and provided at the bottom with aLong lip 13, behind which themiddle part 4 of thespring member 3 can be pushed (see Figures 3 and 4). Themiddle part 4 may be provided with adepression 14 in the place where a connector 11 'is situated, so that lateral displacement of theslat 2 in relation to thespring member 3 is prevented (see Figure 1). - In the mattress base according to the invention two types of
connector 11 are provided; the first type has a buffer block 15 (Figures 1, 2 and 4), while the second has no buffer block (Figure 3). Thebuffer block 15 is fastened against thechamber 12 of theconnector 11, in front of the end of theslat 2, so that it comes to lie above the longitudinal member 1 (Figure 2). The yieldability of aspring member 3 whoseconnectors 11 are provided with abuffer block 15 is thus Limited to the distance between thebuffer block 15 and the top face of thelongitudinal member 1.Buffer blocks 15 of this type are provided in a middle zone of the mattress base according to the invention. The type not provided with a buffer block (Figure 3) allows greater yieldability because theslat 2 can in this case be pressed in inside theLongitudinaL member 1.Connectors 11 of this type which have nobuffer blocks 15 are provided in the shoulder zone of the mattress base according to the invention. Under the head and the feet theslats 2 are rigidly connected to theLongitudinaL members 1. In this way the hardness of the bed can be adapted to the support required by a determined part of the body. - It is obvious that the shape of the
spring members 3 is not restricted to that shown in the drawings. Thus, theends 5 of aspring member 3 may be seated in separate fasteners. Theends 5 may also be joined to the LongitudinaLmembers 1 at a greater distance apart. Aspring member 3 may also carry only oneslat 2, so that that themiddle part 4 is narrower and is provided with only onedepression 14 .
