Cushions with exchangeable cover

Abstract: A cushion is provided, which cushion comprises a filling (1) and a removable cover (4). To avoid folds developping in the cover, the hanging loosely thereof and to enhance its general appearance, the cover is on its inside and the filling is on its outside provided with releasable mutually fitting connections. These connections can be press studs (10), velcro tape, or a snap connection. Thus the removable cover is kept in its position relative to the filling. According to a preferred embodiment, the connections fitted on the filling are plates (21) comprising a hole attached to the filling, and the connections attached to the cover are plates or buttons comprising a mushroom-like extension,fitting in the holes, together forming a snap connection.

Description: The present invention relates to a cushion comprising at least one filling, and a cover provided with at least one opening and enclosing the cushion on both sides. A cushion with such an exchangeable cover facilitates cleaning of the cushion. Cleaning the whole cushion in the washing machine when it has become soiled is indeed a general problem. This often results in a volume reduction and change of shape of the filling so that in the washed state the cushion no longer has an attractive appearance. A cushion will often not fit into a normal domestic washing machine. The above problem which is particularly applicable to garden furniture is solved through the use of an exchangeable cover, since cleaning can then be easily performed by removing the cover and cleaning it separately, for instance in a washing machine. Another advantage of these known cushions with an exchangeable cover is that, should taste, trend or fashion change, a new cover can easily be fitted so that the user could have adapted cushions at a cost considerably smaller than the purchase of completely new cushions would involve. A further advantage of these cushions provided with an exchangeable cover is the fact that the volume of a retail trader's stock could be considerably reduced by having a limited number of fillings in stock in combination with a large number of diversely designed cushions. A wide choice of cushions can hereby be offered to a potential purchaser by the retail trader, while the trader does not need to stock a large volume of complete cushions. Despite all the above mentioned advantages, cushions provided with exchangeable covers have the drawback that the cover will begin to hang loosely and develop folds, certainly at the bottom of the back cushion. Such a cushion does not have an attractive appearance. The cushion known from US-A-2845637 solves these problems. This prior art cushion comprises at least one filling and a cover, enclosing said filling on both sides, the cover being provided with a closable opening for inserting the filling into the cover, the filling on its outside being provided with connection means of the first kind, being releasably connectable with connection means of the second kind, the connection means of the second kind being fit for adhering the cover to the filling. The aim of the present invention is to provide a cushion, as set out above and wherein the connection means can be hidden. This aim is fulfilled by the features of the characterizing portion of claim 1. FR-A-1320876 discloses a releasable cover which can be connected with cushions, but these cushions are fixed and they form part of a seat. The present invention will now be elucidated with reference to the drawings, wherein: fig. 1 shows a partly broken away perspective view of a first embodiment of a cushion according to the present invention; fig. 2 shows a partly broken away perspective view of a fourth embodiment according to the present invention; fig. 3 shows a detail sectional view of a filling as according to the embodiment depicted in fig. 4; and fig. 4 shows a perspective detail sectional view of the connecting means according to alternative embodiments; The cushion shown in fig. 1 is formed by a filling 1 and a cover 4. Arranged around the back filling 3 as shown in the drawing is a back cover 5. The covers 4, 5 are joined to one another. Arranged in the side of each of the covers 4, 5 is a zip closure 7 and 8 respectively so that the covers can be opened for removal of the filling. In order to improve the appearance of the cushion and to prevent folds in the relevant cushions, the filling is provided with a number of press-studs 9. The cover, designated in its entirety by 4, is provided in corresponding positions on the inside with associated negative press-studs 10. Using these press-studs arranged both at the front and rear a good attachment of the cover on the filling is obtained. The cushion also remains properly in place as a result. Owing to the flexibility of the cover 4 with respect to the cushion it is further possible to form so much space between the cover and filling that it is easily possible to reach the relevant press-studs with the hand through the opened zip closure to fasten or release them. A similar consideration applies for the press-studs 9, 10 arranged in the seat cushion. For decorative purposes it is possible to arrange a decorative button 11 on the outside of the cover at the location of the press-studs. According to a preferred embodiment the press-studs placed on either side of a filling are connected to each other so that the filling gives an "upholstered" effect. Through the steps according to the invention this effect is likewise created with a cushion having a loose, exchangeable cover. The filling 1 shown in fig. 2 is formed by a back portion 2 and a seat portion 3. Four filling fixing plates 21 are arranged on the front side of the back portion 2. Four filling fixing plates 21 are likewise arranged on the rear side of the back portion 2, these at corresponding positions. All filling fixing plates 21 are provided with sixteen holes 24 disposed in a circle. All four pairs of oppositely located filling fixing plates 21 are mutually joined by means of stitched seams 22. Two filling fixing plates 21 are arranged against both the upper part and the lower part of the seat portion 3. The two pairs of fixing plates are here also arranged in corresponding positions and mutually joined by means of stitched seams 22. In the case of this cushion, which is suitable for a seat with a high back, the distance in sideways direction between adjacently positioned filling fixing plates amounts to 20 cm, while all filling fixing plates are fixed at a distance of 19.5 cm from the closest side edge. The distance between both filling fixing plates on the seat portion and the front edge of the seat portion amounts to 27.5 cm and between these filling fixing plates and the centre seam 26.5 cm, while the distance between the centre seam and the lower pair of filling fixing plates of the back cushion amounts to 29 cm, and the distance between both horizontal pairs of filling fixing plates on the back cushion is 28 cm, as is the distance between the upper filling fixing plates and the top edge. In the case of a seat cushion with a low back these measurements are similar, except that only one pair of fixing plates is arranged against a side of the back cushion and is located at a distance of 29.5 cm from the centre seam and from the top edge. The dimensions of a single, so-called tabouret cushion correspond with those of the back portion of a cushion with a low back. In the case of a cushion for a bed-seat, four filling fixing plates 21 are arranged against each side of the back portion of the filling, wherein the distance between the filling fixing plates and the side wall always amounts to 23 cm, and the distance between the two upper filling fixing plates and the top edge is 29 cm, as it is between the upper and the lower pair of filling fixing plates, while the distance between the lower pair of filling fixing plates and the centre seam amounts to 29 cm. On the seat portion the distance between the two rows of filling fixing plates amounts to 26 cm, as in the case of the back portion, while both rows of filling fixing plates are each 23 cm removed from the closest edge. The distance between the row of filling fixing plates situated closest to the centre seam and the centre seam is 34 cm, as it is between the row of filling fixing plates situated closest to the bottom seam and this bottom seam. The central row of filling fixing plates is 33 cm removed from the two neighbouring rows of studs. The invention further comprises a cover 4. The cover 4 is formed by a back portion 5 and a seat portion 6. As shown in fig. 2, plates 23 provided with a mushroom-shaped protrusion are arranged against the inside of the back portion 5 and against the inside of the seat portion 6. When the cover 4 is arranged around the filling 1 the mushroom-shaped protrusions are snapped fixedly into the holes arranged in the fixing plates 22. A good fixing of the cover on the cushion, also in the middle of the surfaces, is thus obtained. It will be apparent that the plates 23 have to be arranged on positions in the cover corresponding with the positions of the filling fixing plates 22. To this end, in the case of a cushion with a high back as shown in fig. 2, the plates 23 are fixed in accordance with the following dimensions: the distance between the two rows of plates amounts to 19 cm, while the two rows are each at a distance of 18.5 cm from the closest side edge. The distance between the top edge and the upper row of plates amounts to 27 cm, the same as between the upper and the lower row of plates of the back cushion, while the distance between the lower row of plates of the back cushion and the seam amounts to 28 cm. In the case of the seat portion the distance between the plates and the centre seam is 25 cm and between the plates and the front seam 26 cm. In the case of a seat with a low back the same measurements apply except that on the back portion the distance between the plates and the top edge and the centre seam amounts to 28 cm. The measurements of a cover for a tabouret cushion correspond with those of the cover for a low-backed cushion. In the case of a cushion for a bed-seat the distance between the two rows of studs amounts to 25 cm, while the distance between each row of studs and the closest side edge is 22 cm. On the back portion the distance between the two upper studs and the top edge, between the two upper and two lower studs and between the two lower studs and the centre seam amounts to 28 cm. The distance between the centre seam and the closest row of studs in the seat portion amounts to 33 cm, as does the distance between the front seam and the closest row of studs. The centre row of studs lies 32 cm removed from the other studs. The fixing of the plates will subsequently be described in more detail with reference to fig. 3. As shown in fig. 3, both square filling fixing plates 21 are mutually connected through the filling 1 by means of a stitch connection 22. During fitting of these filling fixing plates the positioning thereof must be performed in accurate manner, since otherwise the holes in the filling fixing plates are not mutually aligned and the stitched seams 22 cannot be arranged mechanically. In order to facilitate positioning the plates take a square form. Each filling fixing plate is provided with sixteen holes which are disposed regularly in a circle. This step is also necessary to enable mechanical fitting of the filling fixing plates. Arranged against the inside of the cover 4 are plates 23. As shown in fig. 4, these plates 23 are also provided with openings 24 ordered in a circle. For attachment the plate 23 is provided with a mushroom-shaped protrusion 25 which is furnished with a saw-cut portion 26. The plate 21 further comprises a funnel-shaped edge 27 which adjoins a central opening 28 arranged in the plate 21. By pressing the cover 4 at the position of the plate 23 against the filling 1 at the position of the plate 21 the mushroom-shaped protrusion 25 will be guided into the funnel 27, wherein the mushroom-shaped protrusion 25 is pressed into the opening 28 until the thickened portion 29 arranged on the end of the mushroom-shaped protrusion is situated on the rear side of the plate 21. A snap connection is thus effected.
