Definitions

  • the present invention relates to a spring frame for supporting a mattress or upholstery with a plurality of profile elements surrounding a support surface and a plurality of strips spanning the support surface and each extending between two mutually opposite profile elements, the two ends of which can each be connected to a profile element by means of a connecting element, in particular on this can be determined.
  • Such spring frames can be used in particular in caravans or cabins of trucks or boats.
  • the connecting elements are riveted to the profile elements. This is labor intensive and increases the weight of the spring frame.
  • the invention is based on the object of eliminating these disadvantages.
  • the connecting elements can be inserted into the longitudinal grooves of the profile elements in a rectilinear movement from above, especially when the groove opening the longitudinal grooves point upwards in relation to the support surface and the ribs or projections of the connecting elements point downwards.
  • This makes it possible to use the connection between the ribs or projections of the connecting elements and the longitudinal grooves of the profile elements as a clamping connection and/or snap-in connection to train. Fixing with rivets or screws is therefore not necessary. The weight of the spring frame can thereby be reduced.
  • a simple insertion of the connecting elements from above can also be promoted in that the profile elements above the groove openings are designed without profile sections and the ribs or projections protrude freely from the connecting elements, i.e. the connecting elements are formed in the direction of the support surface below the ribs or projections without component sections are.
  • one or both longitudinal grooves are arranged in the area of a longitudinal edge of the respective profile element.
  • the ribs or projections of the connecting elements can be arranged in the region of an edge of the respective connecting element facing the profile element.
  • the connecting elements preferably each have a receptacle, in particular a pocket, for one end of a strip designed as a female strip or support strip for spring elements arranged thereon. This ensures a secure connection between the strips and the connecting elements.
  • the strips of the spring frame can each be provided with a connecting element at both ends in advance and inserted as a whole from above into the longitudinal grooves of two opposing profile elements. This enables particularly simple and therefore cost-effective assembly of the spring frame.
  • At least one of the two longitudinal grooves of the profile elements has an undercut and at least a rib of the connecting elements is provided with a locking hook, which engages behind the undercut when the connecting element is installed. This results in an advantageous snap-in connection.
  • At least some of the profile elements are provided with a series of recesses or lugs and the connecting elements are each reciprocally provided with a lug or a recess, the lugs being designed for positive engagement in the recesses.
  • the connecting elements are fixed relative to the profile elements due to the positive engagement of the lugs in the recesses. Even without riveting, unwanted displacement of the connecting elements in the longitudinal direction of the profile elements can be prevented.
  • the recesses or noses of the profile elements are provided on the profile elements according to a predetermined grid dimension. In this way, the distance between the connecting elements from one another in the longitudinal direction of the profile elements and thus also the distance between the strips accommodated by them can be specified. This also simplifies assembly and thereby reduces costs.
  • the recesses or lugs of the profile elements are provided on the outer wall of a groove and the lugs or recesses of the connecting elements are provided on an associated rib or an associated projection. This is also advantageous in production.
  • the profile elements are preferably made of aluminum. Other materials such as wood or plastic are also possible.
  • the connecting elements are preferably made of plastic.
  • two butted ends of two profile elements are connected to one another via an angle-adjustable corner element.
  • the setting angle of the corner elements can preferably be determined by a counter bearing.
  • the counter bearing preferably has at least two mutually offset ribs or projections, which can each be used in one of the two longitudinal grooves of the profile elements in order to connect the corner element to the two profile elements. This uses the longitudinal grooves of the profile elements to also fix the corner elements on the profile elements.
  • the counter bearings also have lugs or recesses which can be inserted in a form-fitting manner into reciprocally designed recesses or lugs of the profile elements. This means that the counter bearings can also be fixed relative to the longitudinal extent of the profile elements.
  • the connecting elements and the counter bearings are connected to the profile elements only via the ribs or projections and, if necessary, the noses or recesses. Rivets or screws for connecting the connecting elements or counter bearings to the profile elements are thereby avoided, which reduces costs and weight.
  • the in Fig. 1 Spring frame 1 shown (only one corner area is shown) consists of four profile elements 2, each of which is connected to one another at right angles via corner elements 3 and surrounds a support surface 4. Between two opposing profile elements 2 (only one profile element is shown) a plurality of support strips 5 are arranged, each of which carries a plurality of spring elements 6 for supporting a mattress or a cushioning element. Instead of the support strips 5 with spring elements 6, spring strips could also be provided, which in turn carry a mattress or a cushioning element.
  • the support strips 5 are each connected at their two ends to the associated profile element 2 via connecting elements 7, as will be described in detail below.
  • the profile element 2 shown is provided with two longitudinal grooves 8 and 9, each with a groove opening 31 pointing upwards with respect to the support surface 4, the longitudinal grooves 8, 9 being vertical in relation to the support surface 4 and perpendicular to the longitudinal extent I of the profile element 2 and are offset from one another parallel to the support surface 4.
  • the groove 8, which is deeper in relation to the support surface 4, is provided with an undercut 10 and has a series of recesses 11, of which only a recess can be seen.
  • the recesses 11 are arranged according to a predetermined grid dimension.
  • the longitudinal grooves 8, 9 are each arranged in the area of a longitudinal edge 32 of the profile element 2.
  • the connecting elements 7 shown are approximately triangular in cross section. They have a rear wall 12 that is perpendicular to the support surface 4 and a lower wall 13 that runs parallel to the support surface 4. Furthermore, the connecting elements 7 are laterally delimited by two essentially triangular side walls 14. Finally, an intermediate wall 15, which also runs parallel to the support surface 4, is provided approximately in the middle of the connecting element 7, which, together with the lower wall 13 and the two side walls 14, forms a receiving pocket 16 for the end of a strip 5.
  • an angle 17 pointing away from the pocket 16 is provided, on which two projections 18 pointing towards the lower wall 13 are formed in a freely cantilevered manner.
  • the projections 18 are designed for positive engagement in the upper groove 9.
  • a recess 19 is provided, which is defined by an upper edge 20 and a side edge 21.
  • Three projections 22 are formed on the upper edge 20 and, like the projections 18, project freely towards the lower wall 13.
  • the projections 22 are designed for positive engagement in the lower groove 8.
  • the projections 22 have locking lugs 23, which engage behind the undercut 10 of the lower groove 8 in a locking manner.
  • the connecting elements 7 have recesses 24 in the area of the upper projections 18 and in the area of the lower projections 22 are provided with recesses 25. In this way, a connecting element 7 produced as a plastic injection-molded part can be easily removed from the mold.
  • the central projection 22 of the connecting elements 7 is provided with a nose 26.
  • the nose 26 is designed so that it can engage in a form-fitting manner in a recess 11 of the lower longitudinal groove 8 of the profile element 2.
  • the respective connecting element 7 is fixed relative to the longitudinal extent I of the profile element 2.
  • the recesses 11 specify the position at which the connecting elements 7 are to be mounted.
  • Fig. 4 is shown how two profile elements 2 butted together are connected to one another via an angle-adjustable corner connector 27.
  • the corner connector 27 consists of two parts 27a and 27b, which are rotatably connected to one another via a hinge-like element 28.
  • a counter bearing 29 is provided, which consists of two parts 29a and 29b, which are pivotally connected to one another via a film hinge 30.
  • the two parts 29a and 29b of the counter bearing 29 can be connected to the two profile elements 2 in the same way as the connecting elements 7, i.e. via upper and lower projections which engage in a form-fitting manner in the upper groove 9 and the lower groove 8 of the profile elements 2.
  • the lower projections can be provided with locking lugs, which can engage behind the undercut 10 of the lower groove 8.
  • the lower projections can be provided with lugs, which can each engage in a form-fitting manner in a recess 11 of a profile element 2, whereby the two parts 29a and 29b of the counter bearing 29 are fixed relative to the longitudinal extent of the respective profile element 2. This also determines the setting angle of the corner element 27.
  • the corner element 7 and the counter bearing 29 can each be made of plastic.
