Definitions

  • the invention relates to a female connector arrangement with a female connector which is convexly curved against the deflection direction and a tension element which extends between the end portions of the female connector and is arranged on the pressure shadow side, the tension element being flexible, for example a belt or a rope, the one between the end portions of the Spring strip extending section of the tension element is shorter than the longitudinal extent of the curved spring strip.
  • Female connector arrangements are used for the spring support of upholstered furniture, for example mattresses in beds or the like.
  • the female connectors are held on two mutually opposite spars arranged below the surface to be sprung.
  • the two bars are connected by two cross bars.
  • a large number of such slats extends between the two spars.
  • Such a spring base is also referred to as a slatted frame in connection with the spring base of a mattress.
  • a slatted frame can also have different spring slats or spring slat arrangements, in particular if a different, in particular softer or harder, deflection characteristic is desired for certain body areas, such as for example the shoulder and / or pelvic area, than in the other areas.
  • spring strips which are curved convexly against the direction of deflection extend between the spars. These are not adjustable in terms of their deflection hardness.
  • CH 245 030 discloses a resilient mattress in which flexible wooden strips are brought into a shape that is curved against the direction of deflection by means of tension elements.
  • the tension element consists of a wire, which is connected to the two ends of such a wooden strip with the interposition one tension spring is connected.
  • the tension element is used to apply the required preload.
  • the compression work is carried out by the tension springs as part of the tension element.
  • AT 383 731 B shows a further exemplary female connector arrangement from the prior art. If hardness adjustability is desired, female connector arrangements are used which have a female connector extending between the two spars and a second female connector arranged below this female connector.
  • WO 2011/103852 A2 Another embodiment for adjusting the deflection hardness of a female connector is disclosed.
  • This known female connector arrangement comprises a female connector which is convexly curved against the deflection direction and a tension element which is connected to end blocks arranged on the pressure shadow side of the female connector.
  • a round bar or a strip with a rectangular cross-section, which have resilient properties, serves as the tension element.
  • compression springs against which the end blocks act when the curved female connector is deflected via angled tabs At the ends of this tension element there are compression springs against which the end blocks act when the curved female connector is deflected via angled tabs.
  • the hardness of the female connector arrangement can be adjusted depending on the spring characteristic of the compression springs used.
  • the hardness in the deflection of this female connector arrangement can also be achieved by changing the distance between the compression springs.
  • a support element is typically also located between the female connector and the tension element.
  • the invention is therefore based on the object of further developing a female connector arrangement of the type mentioned at the outset in such a way that it not only takes advantage of WO 2011/103852 A2
  • Known female connector arrangement which includes due to the tension element also a constant or nearly constant deflection characteristic of the female connector over the life, but which is also less expensive to manufacture and a degree of hardness is simplified.
  • the tension element is flexible. This can therefore be designed, for example, as a belt or as a rope.
  • a belt is provided.
  • the tension element extends between the two end sections of the curved female connector and connects the end sections when the female connector is unloaded over a shorter distance than they are connected to one another by the female connector.
  • the end sections of the female connector if not loaded, are connected to one another by the tension element in a straight line.
  • the spring bar when unloaded, is biased at least to a small extent by the tension element.
  • the elasticity of the tension element is low. The stretch is 2% to 4%.
  • the extensibility of the tension element should not be greater, since the desired tensile forces to be transmitted between the two ends of the tension element connected to the female connector are reduced by the extent of its elongation. Providing a higher degree of stretch leads to a more sensitive deflection, which can also be desirable. In this way, a relatively high pretension can be exerted on the female connector and the desired flexibility can nevertheless be ensured by the stretching of the belt.
  • a flexible tension element can be attached to the female connector in a particularly simple manner.
  • staples, rivets or the like can be provided, for example, if a direct attachment of the tension element to the female connector is provided.
  • the female connector arrangement according to the invention relates to a female connector and a tension element fastened by staples to the end sections of the female connector.
  • the tension element is guided around the ends of the spring bar and then connected to the pressure side of the spring bar with suitable means, for example staples.
  • the connection is non-positive, in this embodiment by the staples by means of a positive connection.
  • an adjustment of the deflection hardness is not provided after the tension element is connected to the female connector.
  • the tension element is connected to the female connector with at least one end with a releasable non-positive connection.
  • the traction means is permanently fixed at one end, for example using staples as described above.
  • the positive connection at the other end can be achieved, for example, in that this end is equipped with a gag or a gag-like element, which can then be inserted into a gag receptacle of the other end section of the female connector.
  • this end of the female connector is bifurcated, the tension element being guided through the fork opening and the gag being supported on the outside of the female connector and thus on its pressure side.
  • the female connector or the fork sections preferably have a plurality of toggle receptacles arranged at different distances from the end thereof.
  • the pulling element can have a handle beyond the gag or the gag-like element, with which the gag can be brought out of the gag receptacle, in alignment with another gag receptacle and then released again. Due to the different distance between these two toggle receptacles, the female connector arrangement then has a different deflection characteristic.
  • the gag remains permanently on the pressure side of the female connector, regardless of whether it is in a gag receptacle or not, it is considered expedient if this end of the female connector is held in a male cap.
  • the toggle receptacles are then at a distance from the actual end of the female connector, namely in front of the female connector cap.
  • the tension element is thus held on the spring strip at this end in the manner described above. It is quite possible if the tension element is connected to both ends of the female connector in this way.
  • a gag is supported on one end of the female connector.
  • the other end of the tension element is then detachably connected to the female connector.
  • the releasable connection between the tensioning element and the female connector is provided by means of Velcro and fleece tapes that are engaged.
  • This connection of the tension element to at least one end section of the spring strip is preferably located on the pressure side of the spring strip, so that the tension element is likewise guided around the ends of the spring strip.
  • the tension element is a belt. Due to the width of the belt, the engaged area between the interacting bands can be dimensioned large enough to withstand even greater shear forces. Either the tension element carries the Velcro strip and the female connector the loop tape or vice versa.
  • connection of the belt with Velcro and Velcro straps to the female connector on its pressure side is also secured by the weight of the mattress. It goes without saying that such a connection of the tension element can also be provided only in one end section of the spring strip, while the other end of the tension element is fixed to the spring strip, for example by staples and thus in a non-detachable manner.
  • the adjustability in the deflection characteristic is very simple in this embodiment. In a first setting of the female connector arrangement, the Velcro and fleece fastener is opened and closed again after the desired length of the tension element has been set, namely by the Velcro tape engaging the Velcro tape.
  • the ends of the female connector engage at the end of the female connector, make sure that by shortening the female connector during a tensioning process, if a female connector pre-tensioning is possible, the female connector is not shortened to such an extent that it threatens to fall out of one or both male connectors.
  • the flexible tension element is stretched between the two strip caps into which the end sections of the female connector are inserted.
  • the traction element can be permanently connected to the strip caps.
  • the connection can also be detachable, for example, as already described above, using Velcro and fleece tapes.
  • the pulling element is fixed to a strip cap and detachably connected to the other strip.
  • the pulling element is detachably connected to a strip cap at one end, while the other end of the pulling element is connected non-detachably, for example by means of staples or the like, to the spring strip.
  • the hardness in the deflection characteristic in the female connector arrangement is not provided by adjusting the tension of the spring element by differently fixing the end sections of the tension element to the end sections of the female connector, but by providing at least one degree of hardness adjustment slide.
  • This measure can of course also be carried out in addition to a possible setting of the deflection characteristic by the measures already described.
  • Such a degree of hardness adjustment slide surrounds the female connector and the tension element, typically in the manner of a cuff, in such a way that such a degree of hardness adjustment slide means that the distance at which the female connector is held by the tension element is smaller, typically significantly smaller than the distance of these elements in the Area of the crown of the female connector when unloaded.
  • the distance between these two elements is greatest in the unloaded state of the female connector arrangement.
  • a degree of hardness adjustment slide is arranged displaceably in the longitudinal extension of the female connector. With this configuration, a hardness degree adjustment can already be carried out with a single hardness degree adjustment slide. If this is brought out from an edge position, in which the female connector and the tension element in the area of the apex of the female connector have their maximum distance from one another, when not under load, and moved in the area of the apex of the female connector, the distance between the female connector is adjusted by the hardness adjustment slide and reduced the tension element.
  • the resulting deflection characteristic is significantly softer than in an embodiment in which the female connector and the tension element are at a greater distance from one another in the region of the apex of the female connector.
  • two hardness degree adjusting slides are used, which are then shifted towards or away from one another, depending on the direction in which the hardness in the compression characteristic is to be adjusted ,
  • the use of a flexible tension element, which is involved in the deflection work of the female connector arrangement, also allows the female connector arrangement to be configured in such a way that part of the load-bearing capacity that is originally assigned to the female connector can be transferred to the tension element. This means that with such a female connector arrangement, the female connector itself can, if desired, be made thinner. This leads to a reduction in the weight of a spring base, especially if it has a plurality or even a plurality of spring strip arrangements of this type. This also saves resources.
  • Such a female connector can, depending on what is to be produced for a deflection characteristic, also from several individual female connectors be constructed. With this concept, the ends of the individual spring strips can be connected to one another or can also be loosely displaceable in the longitudinal axial direction. In the latter case, the female connector is softer overall.
  • the female connector arrangement has a second female connector in addition to the first female connector already described. This is located on the pressure shadow side of the first female connector and is curved in the direction of deflection and thus in the opposite direction to the first female connector. Then the tension element is located between these two mutually convexly curved spring strips.
  • This female connector arrangement can be fastened to a carrier, for example a carrier female connector in the region of the apex of the lower female connector. This carrier is then held on the frame side with respect to the spring base. If the carrier is a carrier spring strip, this is typically connected to the longitudinal bars of the spring base.
  • the tension element is connected with its end sections to both female connectors.
  • This can be achieved, for example, in that the tension element is designed in two layers in the region of its end sections. This can also be achieved by dividing the tension element in the end sections, so that one part is connected to the first female connector and another part to the second female connector. Typically one will provide the division in the middle of the tension element with equally strong female slats.
  • a belt section at the end section can also be designed differently. Typically, the wider end section will then be connected to the female connector with the harder deflection characteristic.
  • the end sections are preferably guided around the ends of the female connectors and fastened to the outer sides of the female connectors.
  • a spring base in the manner of a slatted frame can only have female connector arrangements of the type described above as female connectors.
  • the spring bar arrangements are located in the shoulder and / or pelvic areas of a person lying thereon due to their particular hardness adjustability in the case of reclining furniture.
  • the remaining female connectors can be conventional female connectors.
  • a female connector node is preferably used to connect the tension element with its end section to the ends of such a female connector arrangement.
  • This can be a plastic part, which has receptacles for the ends for the female connectors in the manner of strip caps.
  • the spring strips are preferably tapered in width towards their ends.
  • Such a female connector node comprises a central opening for tensioning the tension element, through which the tension element is guided and is supported on the outside by an abutment, for example a toggle.
  • the tension element which is typically designed as a belt, can have a plurality of toggle pockets which are arranged at a distance from one another transversely to the longitudinal extent of the tension element.
  • a female connector arrangement is suitable for integration into a mattress, as is a female connector arrangement with only two oppositely curved female connectors opposite one another with respect to the tension element.
  • Such mattresses can be used on both sides without sacrificing the quality of the deflection.
  • a female connector arrangement 1 comprises a female connector 2 and a tension element designed as a belt 3 in the exemplary embodiment shown.
  • the female connector 2 is convexly curved, specifically against the direction of deflection.
  • the female connector 2 is made of wood.
  • the belt 3 has a width that is slightly smaller than the width of the female connector 2.
  • the belt is a textile material, the extensibility of which is approximately 2% to 4%. A certain elasticity of the tension element has a favorable effect on the comfort of deflection.
  • the belt 3 is flexible. This material is therefore suitable as a tension element.
  • the belt 3 shows how Figure 1 recognizable, a greater length than the female connector 2.
  • the end sections 4, 4.1 of the belt 3 are shown angled, which is to indicate that the belt 3 with its end sections 4, 4.1 is to be attached to the female connector 2 and these end sections 4, 4.1 are guided around the ends 5, 5.1 of the female connector 2.
  • the end sections 4, 4.1 of the belt 3 are connected in the illustrated embodiment with staples 6 to the pressure side of the female connector 2.
  • the assembly of the female connector assembly 1 of Figure 1 is in Figure 2 shown.
  • the female connector 2 is preloaded to a small extent with regard to its convex curvature by the belt 3 extending between the ends 5, 5.1. This pretension supports the springback behavior of the female connector 2 after a pressure load or in the event of a change in the pressure load and ensures a compression characteristic that remains constant over the life of the female connector 2.
  • Figure 3 shows the female connector arrangement 1 as part of a spring base 7, which is designed in the illustrated embodiment as a mattress base.
  • the spring base 7 has two longitudinal bars 8, 8.1, which are connected to one another at the ends by two transverse bars 9. In the figures, only one cross member 9 is visible due to the cross-sectional representation of the spring base 7.
  • the longitudinal bars 8, 8.1 and the cross bars 9 connecting them form a frame. Between the longitudinal spars 8, 8.1, several female connector arrangements 1 extend parallel and at a certain distance from one another.
  • the spring base 7 can thus be addressed as a slatted frame.
  • the female connector arrangements 1 are held on the longitudinal spars 8, 8.1 each by means of a strip cap 10, 10.1, which in the Figure 3 is shown in section.
  • the ends of the female connector arrangement 1 engage in the receptacles of the ledge caps 10. 10.
  • the ends of the female connector arrangement 1 are held with play in the strip caps 10, so that length compensation movements occur during deflection the engagement in the inguinal caps 10, 10.1 are not impaired.
  • the strip caps 10, 10.1 are connected to the respective spar 8 or 8.1 by means of a mounting part 11, 11.1. Via the mounting part 11, 11.1, the strip caps 10, 10.1 can also be pivoted about the axis of the mounting parts 11, 11.1 by a few angular degrees, in order to allow the top of the female connector 2 to tilt when there is a point load.
  • the deflection characteristic is set by the manufacturer via the belt 3. It is entirely possible to arrange spring bar arrangements with a different deflection characteristic, for example in the pelvis and / or in the shoulder area, with a softer deflection characteristic over the longitudinal extent of the longitudinal bars 8, 8.1.
  • the female connector arrangement 1 is characterized by a particularly pleasant deflection behavior. Particularly in the case of an eccentric load, due to the belt 3 connecting the ends 5, 5.1 and the consequently limited length compensation movement of the female connector 2, a bulge forms on that side of the eccentric pressure action, the length of which between the location of the pressure load and the engagement in the strip holder 10, 10.1 is longer. This is particularly desirable for side sleeping positions, since the recliner then forms in the immediate vicinity of the body of the person lying on both sides, and the width of the recliner is thus significantly smaller than the longitudinal extension of the female connector 2.
  • FIG 4 shows a further female connector arrangement 1.1.
  • the female connector arrangement 1.1 differs from the female connector arrangement 1 solely in that it comprises two hardness adjustment slides 12, 12.1.

Due to the cuff-like edging of the female connector 2 and the belt 3, the degree of hardness adjustment slides 12, 12.1 have a channel 13, 13.1 in which the female connector 2 and the belt 3 are arranged.
  • Figure 4 shows the two hardness adjustment slides 12, 12.1 in their position adjacent to the strip caps 10, 10.1 and thus in a position in which the female connector arrangement 1.1 has its greatest deflection hardness.
  • Figure 5 shows an adjustment of the degree of hardness adjustment slide 12, 12.1 compared to the female connector 2 and the belt 3 with a significantly softer deflection characteristic than when the same in the position Figure 4 , as indicated schematically by the different width of the block arrows as a measure of the differently acting pressure load. From the representation of the Figure 5 it is clear that the belt 3 is approximated to the curved shape of the female connector 2 by moving the hardness adjustment slide 12, 12.1.
  • Figure 5 are the hardness adjustment slide 12, 12.1 symmetrical with respect to the apex of the female connector 2 with respect to its edge position in the Figure 4 been adjusted. If an asymmetrical deflection characteristic across the width of the female connector arrangement 1.1 is desired, the degree of hardness adjustment slides 12, 12.1 can also be brought into an asymmetrical position with respect to the central longitudinal plane of the spring suspension 7. For example, the hardness adjustment slides 12, 12.1 can both be placed in one half of the female connector 2, with the result that the deflection characteristic in the right area of the female connector arrangement 1.1 is then softer than in the left area.
