Definitions

  • the present invention relates to a spring mattress comprising springs enclosed in casings, a so-called pocket mattress.
  • the invention is also related to a method and device for producing such mattresses.
  • a common technique of making spring mattresses is the so-called pocket technique.
  • the springs are enclosed in pockets, i.e. they are individually enclosed by a casing material.
  • the springs will be relatively individually resilient so that they can flex individually without affecting the neighboring springs and, thus, the comfort to the user increases since the weight will be distributed more uniformly over the surface that receives the load.
  • a drawback of this type of mattress is, however, that it is difficult to provide thin mattresses. If the length of the springs is reduced without a corresponding reduction of the width, the spring will, especially when the length approaches the length of the diameter of the spring, have a tendency to turn in the casing, which dramatically deteriorates the comfort of the mattress.
  • the existing technique requires the use of a much larger number of springs. Consequently the manufacturing will be considerably more expensive and more complicated. Besides it is difficult to prevent such mattresses from also being stiffer since too thin spring wires cannot be used.
  • spring mattresses for many purposes where thinner mattresses are required, such as for overlay mattresses, seat cushions and the like.
  • spring mattresses have several properties making it desirable to use them also in these contexts, such as excellent comfort, individual flexibility, a long life and easy and inexpensive manufacture.
  • the document CN 206590894 U also discloses a spring mattress according to the state of the art.
  • a spring mattress comprising a plurality of interconnected coil springs enclosed in casings, wherein for at least one of the springs, casing portions arranged at the ends of the spring are connected to each other through the spring via a joint, and the joined casing portions comprising an opening through the spring.
  • This mattress is of the general type as disclosed in US 6591438 , US 7748065 and US 8087114 by the same applicant, which are herewith incorporated by reference, and thus has essentially all advantages that are associated with this type of mattress, such as the possibility of making the mattress thin, the advantageous bias of the springs etc.
  • the inventive mattress also gives a number of additional advantages.
  • the aeration and ventilation through the mattress is improved.
  • a significant volume of moisture leaves the body during sleep. Thanks to the improved aeration/ventilation, this moisture will be taken care of more efficiently, and without making the mattress damp.
  • the moisture will more efficiently be removed from the user's body, and away from the mattress. Further, this improves the comfort and sleeping quality, and will enable a more stable sleeping temperature and humidity for the user. This will make temperature regulation for the user easier.
  • the reduction of damp and moisture in the mattress will counteract assembly and growth of dust mites, mold, bacteria etc, and will thereby maintain the mattress in a hygienic condition for a much longer time. This will also reduce the risk for development of allergies. It will also reduce the risk of unwanted odors.
  • the improved aeration and ventilation will make it possible to maintain the mattress in a clean and hygienic state for a much longer time, thereby increasing the longevity of the mattress.
  • the present invention is based on the realization that in this particular type of mattress, i.e. a pocket spring mattress in which the casing portions arranged at the ends of the spring has been joined to each other through the spring, aeration and ventilation can easily be provided by provision of an opening through the joint, i.e. through the spring. Not only does this greatly improve the aeration and ventilation through the mattress, but also it does not in any way deteriorate or affect the other properties of the mattress.
  • the mattress functionally performs in the same way as previously known mattresses of the same type, but with a greatly improved aeration and ventilation.
  • each pocket i.e. the casing enclosing each spring
  • each spring is formed as a toroid, having a doughnut shape, forming a circular compartment enclosing the spring.
  • the casing portions may be indirectly joined, i.e. without being in direct contact with each other. However, preferably the casing portions may be moved so far towards each other as to contact each other. It is also preferred for the casing portions at the spring ends to be moved so far towards each other that the springs are biased. By letting the casing portions contact each other there is only a need for one common opening through the spring.
  • connection of the casing portions is preferably given such a size and shape that the connection obtains sufficient strength and stability. Furthermore, the shape and size of the connection can be varied to give different degrees of bias of the springs. In this way, it is possible to easily vary the bias between different mattresses, and also between different springs in one and the same mattress. Preferably, the connection forms a symmetric joint area.
  • the opening is arranged within the perimeter of the joint of the casing portions.
  • the opening may have various shapes, such as quadratic, rectangular or oval. However, preferably the opening has a symmetric shape, and most preferably the opening is substantially circular.
  • the average diameter of opening is preferably within the range 2-50% of the average diameter of the spring, and preferably within the range 5-30%, and most preferably within the range 10-25%.
  • the ratio of the average spring diameter to the average diameter of the opening may be between 2 and 8, preferably between 3 and 6, and most preferably between 3 and 4.
  • the opening may have an average diameter in the range of 0.1-3 cm, and preferably within the range 0.5-2 cm, and most preferably within the range 0.7-1.5 cm.
  • the casing portions are connected by a plurality of welding points distributed around the opening.
  • the joint may comprise 2, 3, 4, 6 or 8 welding points.
  • the casing portions may be connected by a continuous welding around the opening. By providing welding around the opening proper strength is maintained in the interconnection in spite of the opening.
  • the welding points may be symmetrically arranged around the opening to ensure sufficient strength in the interconnection.
  • the casings form a plurality of strings interconnected side by side, each string comprising a continuous casing material, the casings being defined by at least one longitudinal connecting line extending parallel to the longitudinal direction of the string and a plurality of transverse connecting lines extending transversely to the longitudinal direction of the string, and coil springs arranged in the casings of the string.
  • the connecting lines are arranged at the side of the springs, and thus between neighboring springs.
  • Connecting lines extending over the ends of the springs cause problems with so-called false lofts, that is accumulations of material over the springs which increase the height of the mattress but do not exhibit resilience and, thus, do not add to the comfort of the mattress. On the contrary, such false lofts can give a lumpy and uneven surface, which reduces comfort.
  • By arranging the connecting lines With the new mattress, the occurrence of such false lofts is effectively avoided, and the height of the mattress corresponds substantially to the height of the springs, with a single smooth casing layer over the ends of the springs.
  • the relatively smooth casing at the ends of the springs also gives the possibility of easily fastening the end portions of the casing to each other through the springs, by, for instance, welding, which enables very efficient and cost-effective manufacture.
  • the longitudinal connecting lines and the transverse connecting lines of the strings preferably extend substantially at right angles to the longitudinal axes of the springs. Furthermore, the longitudinal connecting lines and the transverse connecting lines of the strings preferably extend in essentially the same plane, which plane preferably is substantially perpendicular to the longitudinal axes of the springs.
  • the strings Connecting the strings to each other via the longitudinal connecting lines has been found very advantageous.
  • the longitudinal connecting lines which typically consist of welds, in many cases projecting from the string, an advantageous separation of the strings is automatically obtained.
  • the strings are in this way attached to each other only along a line, and preferably only at a number of points along this line. This has been found to give a very flexible mattress, where the springs are extremely movable in relation to their neighbors.
  • the casings are formed by a relatively large upper sheet and a relatively large lower sheet, the sheets being connected together along longitudinal and lateral connections lines, e.g. forming a checkerboard pattern, thereby forming the individual pockets for the springs.
  • the pockets are integrated with each other be the same material not only in one direction, as in the above-discussed string embodiments, but in two directions, i.e. both in a length and width dimension.
  • the casing is preferably a textile material, and preferably a weldable textile material.
  • connection of the casing portions at the ends of the spring may be such that the spring is biased.
  • a mattress of lesser thickness, than what is otherwise achievable, may be provided.
  • the connecting means may be arranged in such manner as to provide a desired overlap between the casing portions, the thus-obtained overlap determining the bias of the spring.
  • the spring may be biased so that the length of the spring in the biased state is smaller than 2/3 of the length of the same spring in a non-biased state, preferably smaller than 1/2.
  • the spring may have a height which is less than the width of the springs, preferably less than 2/3 of the width, and most preferred is about 1/2 of the width or less.
  • the spring mattress comprises a plurality of biased springs, wherein at least some of the springs are differently biased.
  • the springs may then be differently biased so as to form portions of the mattress of varying thickness.
  • a device for biasing coil springs enclosed in casings comprising an inserter and a counteracter arranged at a distance therefrom, the inserter and the counteracter being adapted to perform a relative displacement towards and away from each other to bring casing materials at the spring ends of a spring arranged there between towards each other through the spring, such that the spring becomes biased, and an interconnector for forming a joint connecting the thus brought-together casing materials from the two spring ends, characterized in that the device further comprises a punch for punching an opening in the interconnection between the casing materials from the two spring ends.
  • the means for moving casing portions arranged for the ends of the spring towards each other and connecting them to each other comprises welding equipment movable in the spring direction.
  • the welding equipment is preferably adjustable, the size of the generated weld thereby being controllable.
  • the inserter and counteracter may be arranged both to provide the connection, e.g. by welding, and to form the opening, e.g. by punching.
  • a method for manufacturing a spring mattress comprising a plurality of interconnected coil springs enclosed in casings, comprising the steps of enclosing the springs in a casing material, biasing at least one of the springs, and interconnecting the springs, the step of biasing the springs comprising the partial steps of moving casing portions arranged for the ends of the spring towards each other, through the spring and interconnecting them by means of a joint, and further comprising forming an opening in the joint, through the spring.
  • the step of forming the opening in the joint may be performed prior to forming the joint, after formation of the joint, or simultaneously with the joint formation.
  • the forming of the opening may be made prior to forming the joint, the forming of the opening may be made prior to insertion of a spring into the casing/pocket, or alternatively after insertion of the spring.

  • the strings comprise casing material of a folded piece of material, where the fold line extends in the longitudinal direction of the string.
  • the closing longitudinal connecting line 5 is arranged at the opposite side of the string. Transverse connecting lines then extend between the fold line and the longitudinal connecting line.
  • the springs are here oriented in the pockets so that the connecting lines are arranged at the side of the springs and, thus, between neighboring springs.
  • the casing material portions at the ends of the springs are thus essentially free of other connections.
  • the casing portions arranged at the ends of the springs are moved towards each other, through the spring, and connected to each other by connecting means 7 to provide at least a certain degree of bias.
  • the casing portions are moved so far towards each other as to make contact with each other, but of course it is possible to interconnect them also otherwise, by wire, a long clamp or the like.
  • the connecting means may consist of a mechanical connecting element, such as a clamp, a rivet or the like, or by a surface joint, such as an adhesive, a weld or the like.
  • Other fixing elements are, however, also conceivable.
  • the load on the fixing element is normally small since the fixing elements are only loaded when the mattress is unloaded, whereas there is no load at all when the mattress is loaded.
