Definitions
- the present invention relates to a framework, espe- cially for furniture and other fittings, comprising a frame having a plurality of interconnected frame members, said frame preferably being adapted to accommodate a filling in the space defined by the frame members, and a cover extending over the frame and the filling.
- Securing of covers to furniture frameworks is tradi ⁇ tionally carried out by nailing or tacking, frequently combined with gluing, which requires a yieldable framework material. If this material is metal, other solutions must be applied, which in many cases are time-consuming and ne- cessitate a more complicated basic structure.
- fur ⁇ niture frameworks are often made of wood. However, there is a tendency towards deterioration of the quality of wood from all over the world. The trade is alarmed at this fact, and therefore attempts are being made to produce an alternative to wooden frameworks.
- DE-2,433,638 discloses a cover clamping device in which a strip is snapped into a groove.
- the strip as well as the groove are made of flexible plastic.
- One drawback of this device is the obvious risk that the strip falls out of the groove, if one pulls the cover so hard that the strip and/or the groove are deformed by deflection.
- the object of the present invention is to provide a framework which makes it possible to readily and nicely secure a cover to a framework of an optional material.
- the object is achieved in that at least two opposite frame members are formed with at least one longitudinal, undercut groove which has sides of different length and a bottom inclined relative to the plane of the groove open ⁇ ing and into which a strip is insertable the length of which approximately conforms to the length of the groove, and the width of which is greater than the width of the groove opening but smaller than the width of the groove bottom and the thickn&ss of which is substantially smaller than the width of the groove opening, an edge portion of said cover being disposable about said strip so as to cover at least part of one flat side of the strip and an edge side adjoining this flat side, whereby after posi ⁇ tioning of the -strip in said groove and as the cover is being pulled, the cover is secured to the groove by incli ⁇ nation of the strip in the groove and, thus, clamping of the edge portion between the strip and the wall of the groove.
- the framework can now be made of an optional mate ⁇ rial, especially metal which can withstand higher loads than wood. Moreover, it is possible to define more accur- ate performance characteristics for the material, such as tensile yield limits and ultimate strength.
- a metal frame ⁇ work is also more hygienic and can be made with a lower weigh .
- a further advantage of the present invention is the use of a minimum of loose means of attachment both for mounting the frame proper and the filling and for se ⁇ curing the cover. As a result, the framework is quickly mounted and thus also inexpensive.
- a still further advantage is that the design of fas- tening tabs on the frame members makes the mounting of the filling extremely well suited for automation, and in that case all fastening tabs are fixed simultaneously. This implies, of course, great savings.
- Fig. 1 is a cross-sectional view of a frame member according to the invention
- Fig. 2 is an enlarged view of the groove in the frame member, a strip with a cover secured thereto being arranged in the groove, Figs. 3A-G show the same detail as Fig. 2, but the strip is illustrated in a number of conceivable posi ⁇ tions,
- Fig. 4 illustrates part of a mounted frame with a corner piece
- Fig. 5 illustrates a corner piece before mounting in the framework
- Fig. 6 illustrates a frame member and a bottom slat attached thereto, the frame member also being provided with fastening tabs,
- Figs. 7A-H illustrate a number of possible embodi ⁇ ments of the fastening tabs
- Fig. 8 shows an alternative embodiment of the strip with the cover secured thereto.
- the drawing illustrates a framework for furniture and other fittings.
- the framework is preferably used for beds, but can also be used for car seats and for mounting of a fabric on e.g. exhibition screens or for domestic use as an alternative to wallpaper.
- the framework comprises a frame 1 having a plurality of interconnected frame members 2, said frame preferably being adapted to accommodate a filling in the space de ⁇ fined by said frame members, and a cover 3 extending over the frame 1 and the filling.
- the frame member 2 which as shown in the drawing is appoximately rectangular in cross-section has, in its lower side, an undercut groove 4 adjacent the side of the frame member 2 which is in ⁇ tended to be directed outwards when mounted.
- the undercut groove 4 has sides 6, 7 of different length and, consequently, an inclined bottom 8.
- a strip or section 5 for securing the cover 3 is in ⁇ sertable in the groove 4.
- the section has a length ap ⁇ proximately conforming to the length of the groove, a width greater than the width of the groove opening but smaller than the width of the groove bottom 8, and a thickness which is considerably smaller than the width of the groove opening.
- the section 5 is, in one embodiment, J-shaped in cross-section with a long web and short flange. An outer edge of the cover 3 is clamped between the flange and web of the J, as shown in Figs. 2 and 3.
- the cover 3 covers at least part of one flat side of the section 5 and an edge side adjoining the flat side and is laid round the two edge sides of the section and the in ⁇ termediate flat side formed by the outside of the web of the J.
- the section 5 can be positioned in the groove 4 in various ways, as illustrated in Fig. 3.
- the sec ⁇ tion preferably is positioned in the groove as shown in Fig. 2.
- the transition between the groove, opening and the side of the frame member which is intended to be directed outwards when mounted is gently rounded so that the cover can be nicely mounted and will not be worn off by any sharp edges.
- the flange and web of the J can of course be upset at certain intervals for improved securing of the edge portion of the cover 3.
- Either the flange or the web of the J can also be provided with pins and mating holes or recesses in the other part of the J at certain intervals, so that on compressing the J, the cover will be forced by the pins into the holes or re-mitteds.
- the strip or section 5 can, of course, be designed in various ways. The essential thing is that it somehow secures the outer edge of the cover 3.
- Fig. 8 An example of a different embodiment ⁇ f the strip is shown in Fig. 8.
- the strip 5 is
- the cover 3 is sewn onto the strip.
- the cover can also be secured to the strip in some other way, e.g. by gluing.
- the frame members 2 are, as shown in Fig. 4, con- nected to each other by corner pieces 10 which are insert ⁇ able in the frame members.
- Fig. 4 illustrates an end frame member 15 and a longitudinal frame member 16 which are joined by a corner piece 10.
- the corner pieces are shown in Fig. 5 and are made of a sheet-metal L-section of which the short leg is formed with two V-shaped recesses 11 at a mutual distance a.
- the long leg is bent along lines extending at right angles to the short leg and through the points of the V recesses 11.
- the portion formed between the V recesses is secured in the portions extending outside the V recesses by upsetting. Thus, no loose means of attachment are required.
- the corner piece 10 is then inserted in two frame members 2 and fixed by means of blind rivet nuts 14.
- bottom slats 13 are attached to the horizontal flange 12 which is provided at the lower part of the side of the frame members 2 which is directed to the centre of the bed, as appears from Fig. 6.
- the bottom slats 13 are preferably made of metal and attached to the flanges 12 on the long sides by e.g. upsetting.
- the filling consists of a lower and sometimes also an upper spring assembly.
- spring assemblies are secured in an excellent way.
- the sides of the frame members 2, which are directed to the centre of the bed, and optionally also the upper sides of the frame members 2 and optionally also the upper sides of the frame members 2 are provided with punched fastening tabs 9. These tabs are best seen in Fig. 6.
- the upper spring assembly is fixed by means of the fastening tabs 9 in the upper side of the frame
- the lower spring assembly is fixed by means of the fastening tabs 9 in the side of the frame member 2 facing the centre of the bed. Since no loose means of attachement are required, such fixing operations are well suited for automation, and in that case all fastening tabs 9 are secured in a single operation.
- the appearance of the tabs may vary, some examples being shown in Fig. 7.
- plates extending diagonal ⁇ ly across the corners can be mounted on the lower side of the frame.
- These plates can also be formed with recesses for mounting legs and possibly also for mounting bedsteads, lighting, bedside tables, and/or other fit ⁇ tings.
- Fastening means for fittings can also be arranged in the frame itself adjacent the corners, for example in the form of bores.
- the blind rivet nuts 14 for fixing the corner piece 10 in the frame members 2 can also be used as fastening means for various fittings.
