Definitions

  • the present invention relates to a spring frame for supporting a mattress or upholstery, comprising several profile elements surrounding a support surface and several slats spanning the support surface, each extending between two opposing profile elements, the two ends of which can each be connected to a profile element by means of a connecting element, in particular fixed to it, wherein at least a part of the profile elements is provided with two longitudinal grooves parallel to each other and extending in the longitudinal direction of the respective profile element, wherein the two grooves are offset from each other in height and perpendicular to the longitudinal extension of the respective profile element and parallel to the plane of the support surface with respect to the support surface of the spring frame, and wherein the connecting elements have at least two ribs or projections parallel to each other and offset from each other according to the longitudinal grooves of the profile elements, each of which can be inserted into one of the two grooves in order to connect the connecting element to the respective profile element.
  • spring frames can be used particularly in caravans or in the 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.
  • a spring frame with the features of the preamble of claim 1 is made of DE 20 2004 010 852 U1 known. Similar spring frames are also known from the DE 84 29 877 U1 , the DE 23 18 513 A1 and the DE 76 25 905 U1 known.
  • the invention is based on the objective of eliminating the aforementioned disadvantages.
  • the staggered arrangement of the longitudinal grooves of the profile elements allows the connecting elements to be inserted into the longitudinal grooves of the profile elements in a straight line from above. This is achieved in particular by ensuring that the groove openings face upwards with respect to the support surface and the ribs or projections of the connecting elements face downwards. This makes it possible to design the connection between the ribs or projections of the connecting elements and the longitudinal grooves of the profile elements as a clamping and/or snap-in connection. Therefore, fastening by rivets or screws is unnecessary. This can reduce the weight of the spring frame.
  • one or both longitudinal grooves are arranged in the region of a longitudinal edge of the respective profile element. Accordingly, the ribs or projections of the connecting elements can advantageously be arranged in this way. be arranged in the area 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 spring strip or support strip for spring elements arranged thereon. This ensures a secure connection between the strips and the connecting elements.
  • the slats of the spring frame can each be pre-fitted with a connecting element at both ends 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 is provided with an undercut and at least One rib of the connecting element is provided with a locking hook which, when the connecting element is mounted, engages behind the undercut. This results in an advantageous snap-fit connection.
  • At least a portion 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 with the recesses.
  • the positive engagement of the lugs with the recesses secures the connecting elements relative to the profile elements. This prevents unintentional displacement of the connecting elements in the longitudinal direction of the profile elements, even without riveting.
  • the recesses or lugs of the profile elements are provided according to a predetermined grid dimension. This allows the spacing of the connecting elements from each other along the length of the profile elements, and thus also the spacing of the strips they accommodate, to be predetermined. This also simplifies assembly and therefore 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 projection. This is also advantageous in manufacturing.
  • 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 each other via an angle-adjustable corner element.
  • the angle of the corner elements is preferably determined by a counter bearing.
  • the counter bearing preferably has at least two offset ribs or projections, each of which can be inserted into one of the two longitudinal grooves of the profile elements to connect the corner element to the two profile elements. This utilizes the longitudinal grooves of the profile elements to also secure the corner elements to the profile elements.
  • the counter bearings also have lugs or recesses that can be inserted into reciprocally shaped recesses or lugs of the profile elements in a form-fitting manner.
  • the counter bearings can also be positioned relative to the longitudinal extent of the profile elements.
  • the connecting elements and counter bearings are attached to the profile elements only via the ribs or projections and, if applicable, the lugs or recesses. This eliminates the need for rivets or screws to connect the connecting elements or counter bearings to the profile elements, thus reducing costs and weight.
  • the in Fig. 1 The spring frame 1 shown (only one corner section is depicted) consists of four profile elements 2, each connected at right angles to the others via corner elements 3 and surrounding a support surface 4. Between two opposing profile elements 2 (only one profile element is depicted), several support rails 5 are arranged, each carrying a plurality of spring elements 6 for supporting a mattress or upholstery element. Instead of the support rails 5 with spring elements 6, spring rails could also be provided, which in turn support a mattress or upholstery element.
  • the support rails 5 are connected at both ends to the associated profile element 2 via connecting elements 7, as described in detail below.
  • the profile element 2 shown is provided with two longitudinal grooves 8 and 9, each with a groove opening 31 facing upwards with respect to the support surface 4.
  • the longitudinal grooves 8 and 9 are offset from each other vertically with respect to the support surface 4, perpendicular to the longitudinal extent I of the profile element 2, and parallel to the support surface 4.
  • the groove 8, which is deeper with respect to the support surface 4 is provided with an undercut 10 and has a series of recesses 11, of which Only one recess is visible.
  • 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 have an approximately triangular cross-section. They have a rear wall 12 perpendicular to the support surface 4 and a lower wall 13 running parallel to the support surface 4. Furthermore, the connecting elements 7 are laterally bounded by two essentially triangular side walls 14. Finally, an intermediate wall 15, also running 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 angled section 17 pointing away from the pocket 16 is provided, on which two projections 18, pointing towards the lower wall 13, are freely cantilevered.
  • the projections 18 are designed for positive engagement with the upper groove 9.
  • a recess 19 is provided, which is defined by an upper edge 20 and a lateral edge 21.
  • Three projections 22 are formed on the upper edge 20, which, like the projections 18, project freely towards the lower wall 13.
  • the projections 22 are designed for positive engagement with the lower groove 8.
  • the projections 22 have locking lugs 23 which engage behind the undercut 10 of the lower groove 8 in a snap-fit 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. with recesses 25. This allows for easy demolding of a connecting element 7 manufactured as a plastic injection molded part.
  • the central projection 22 of the connecting elements 7 is provided with a lug 26.
  • the lug 26 is designed such that it can engage positively in a recess 11 of the lower longitudinal groove 8 of the profile element 2. This secures the respective connecting element 7 relative to the longitudinal extent I of the profile element 2.
  • the recesses 11 determine the position in which the connecting elements 7 are to be mounted.
  • FIG. 4 Figure 2 shows how two butted profile elements 2 are connected to each other via an angle-adjustable corner connector 27.
  • the corner connector 27 consists of two parts 27a and 27b, which are rotatably connected to each other via a hinge-like element 28.
  • a counter bearing 29 is provided to define an adjustment angle.
  • This counter bearing consists of two parts 29a and 29b, which are pivotably connected to each other 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 that engage positively in the upper groove 9 and the lower groove 8 of the profile elements 2.
  • the lower projections can be provided with locking lugs that can engage the undercut 10 of the lower groove 8 in a snap-fit manner. Furthermore, the lower projections can be provided with lugs which can engage positively in a recess 11 of a profile element 2, thereby fixing the two parts 29a and 29b of the counter bearing 29 relative to the longitudinal extent of the respective profile element 2. This also determines the adjustment angle of the corner element 27.
  • the corner element 7 and the counter bearing 29 can each be made of plastic.
