Definitions

  • a wall of an elevator car from two or more wall elements by connecting two adjacent wall elements with each other. This makes it possible, for example, to introduce the individual wall elements through a shaft door and assemble them in the elevator shaft to the larger cabin wall.
  • a cabin wall which is larger than the shaft door, can also be removed element by element from the elevator shaft in the opposite way.
  • the illustrated method is not suitable for joining wall elements of composite panels - for example, honeycomb composite panels or foam core composite panels - since they usually have no connection elements for attaching said cross member.
  • connection means which serve for connecting sandwich panels arranged between two cover plates filling material.
  • the connection means described assume that the sandwich panels are provided along their edges to be joined with a plurality of grooves formed in the cover plates.
  • outer cover-connection profiles which press the sandwich plates to be joined in each case an edge region to each other frontally.
  • Object of the present invention is to provide a connecting device for the connection of two wall elements of an elevator car, with which plate-shaped wall elements can be connected without integrated connection elements, which has a high rigidity, and which is mountable from the inside of the elevator car, wherein It must be ensured that neither the wall elements nor parts of the connecting device can be deformed or destroyed by tightening tensioning devices in the areas of the connecting zones.
  • a connecting device serves for the connection of a first, in particular plate-shaped wall element and a second, in particular plate-shaped wall element of an elevator car, which is adjacent thereto and is separated from the first by a gap.
  • the gap may extend over the entire mutually facing end faces of the two wall elements. This allows the formation of simple end faces and a connection on the largest possible length.
  • the gap may equally extend only over portions which allow a gripping behind the wall elements by hand or a mounting tool, while touching the wall elements in the remaining area with their end faces.
  • the connecting device advantageously extends over the entire gap length, which ensures maximum rigidity and advantageously isolates the elevator car thermally and acoustically against the elevator shaft.
  • the gap widths may, for example, be in the range of 50 to 100 mm in order to allow the handrail to engage behind the wall elements.
  • a connecting device comprises a first plate element with a first edge region for resting on a first wall surface of the first wall element, a second edge region for resting on a second wall surface of the second wall element and a first central region connecting these two edge regions and covering the gap second plate member with a third edge region for support a third wall surface of the first wall element, a fourth edge region for resting against a fourth wall surface of the second wall element, and a second middle region connecting these two edge regions and likewise covering the gap.
  • the first and third edge regions and the second and fourth edge regions thus form receiving grooves for receiving the mutually facing edge regions of the first and second wall element.
  • the two plate elements are designed so that their two central regions touch each other in the mutually braced state. This ensures that neither the connecting device nor the wall elements can be deformed or destroyed, because the screws which clamp the two plate elements with the wall elements are over-tightened.
  • connection device interconnect mutually offset wall elements or wall elements which form an angle with each other.
  • the first plate element is then movably connected to the second plate element in a first direction, so that the above-mentioned receiving grooves are variable in their width.
  • the connecting device comprises clamping means for clamping the first and the second central region against each other in the mentioned first direction. Due to the bracing, the first wall element can be clamped in the variable receiving grooves between the first and third edge regions and the second wall element between the second and fourth edge regions.
  • the clamping means and higher normal forces between the edge regions of the plate elements and the wall surfaces of the wall elements generated and thus a higher frictional engagement can be taught. Also, this can increase the rigidity of the entire connection in all directions.
  • the clamping means comprise in a preferred embodiment, one or more bolts, preferably designed as clamping screws, which cooperate with associated internal threads, preferably with threaded nuts, and brace the two central regions of the plate elements against each other in the first direction when screwing.
  • the clamping screws can pass through through holes in both plate elements and be screwed with separate nuts, which are located behind the screw heads facing away from the plate element.
  • the internal threads can also be in the screw heads be turned away plate member integrated by, for example, an internal thread is formed in the central region or a threaded sleeve fixedly connected to the central region.
  • bolts connected to the central region of the one plate element projecting towards the central region of the other plate element can pass through a through-hole therein and with an internal thread present in this central region or behind this center region Threaded nut is screwed.
  • the tensioning means may comprise one or more elastic spring elements, in particular helical springs, which connect the two plate elements elastically with one another or pull one against the other.
  • the spring elements space the plate elements in the first direction while at a distance which is less than the wall thickness of the wall elements, so that the spring elements in the assembled state, the two plate elements brace against each other and clamp the wall elements frictionally in the grooves.
  • the spring members allow the above-described initial large spacing of the plate members from each other such that the second plate member can be inserted through the gap.
  • the first direction referred to below is the direction which extends substantially perpendicular to the cleavage plane. As a cleavage plane while the plane is referred to, which extends between the two opposite end faces of the adjacent wall elements.
  • the two central regions of the plate elements touch each other in the mutually strained state.
  • This increases the rigidity of the connecting device, since both plate elements are positively supported against each other.
  • the plate elements are designed so that when clamping the plate elements with the wall elements on the one hand no plastic deformation of the plate elements and on the other hand sufficient, but not unduly high clamping forces result. Manufacturing and assembly tolerances can be compensated thanks to the elasticity of the plate elements.
  • the first central region is connected to both the first and the second edge region via an outer oblique surface.
  • the connecting device pushes apart the two wall elements by the oppositely inclined outer inclined surfaces sliding on the edges of the two wall elements, thereby distancing the wall elements to an intended gap width.
  • the outer inclined surfaces cause a correct positioning of the connecting device in the gap, whereby an appropriate distribution of the force exerted by the clamping means on the wall elements normal forces and thus the provided frictional engagement is ensured.
  • the second central region may be connected to the third and / or fourth edge region of the second plate member via further outer inclined surfaces adjacent to the third and fourth edge region of the second plate member, said inclined surfaces are inclined so that they in Direction towards the respective adjacent edge area lead away from the first plate element.
  • the first central region has two middle oblique surfaces, which in With respect to the above-defined first direction are each inclined in opposite directions, while the second central region also has two central inclined surfaces which have the same opposite inclinations as the central inclined surfaces of the first central region and are arranged so that in the clamped state of the two plate elements, the central inclined surfaces of first central region rest on the central inclined surfaces of the second central region.
  • the two plate elements are positioned transversely to the longitudinal direction of the existing gap between the wall elements relative to each other and fixed immovably in said direction.
  • the inclined surfaces are advantageously produced by folding the middle regions. These bends in the longitudinal direction of the gap, i. in the longitudinal direction of the connecting device, also increase the rigidity of the connecting device in the longitudinal direction.
  • at least one of the two plate elements may additionally or alternatively comprise further bends and / or reinforcements, in particular ribbing, material thickening or the like. Such bends and / or reinforcements can also be made in the transverse direction of the connecting device, i. be formed between the two wall elements.
  • a seal is arranged in the edge region of the first and / or second wall element facing the gap, which seals this edge region of the wall element against the first and / or second middle region of the plate elements.
  • the seal can be arranged, for example, in receiving grooves in the end faces of the wall elements and have an elastic flange which, in the mounted state, presses against a central region, in particular against an outer oblique surface and thus seals the wall elements against the corresponding plate element.
  • a receiving groove formed by the first and third edge regions or by the second and fourth edge regions of the first and second plate elements is first pushed over an edge region of the first wall element.
  • the plate elements which are sufficiently spaced apart from one another via the clamping means are made oblique to the gap plane and subsequently the second plate element is pushed through the gap so that its third and fourth edge regions engage behind the third or fourth wall surface of the first or second wall element.
  • the first and the second central region are clamped by the clamping means against each other in the first direction, for example, tightened by the clamping screws or the nuts are screwed onto fixed bolts. This closes the receiving grooves and the first wall element is clamped between the first and third edge region, the second wall element between the second and fourth edge region.
  • the connecting device has at least one of the outer oblique surfaces described above, then unless the connecting device is already in the final assembly position by chance and the wall elements are not already in place their intended distance from each other, at least one edge of a wall element in contact with at least one outer inclined surface which is inclined towards the first direction. With mutual approach of both plate elements in the first direction, effected by the tensioning means acting in this direction, slides this edge on said outer inclined surface, whereby the connecting means automatically positioned in its intended position in the gap, preferably centered, and the two wall elements to the intended Gap width are distanced from each other.
  • first and second wall element can be connected to one another from the inside of the elevator car, whereby the second plate element loosely connected to the first plate element and movable in the first direction relative to the first plate element can be handled well via the first plate element and also over the inclined surfaces themselves positioned in the correct position.
