Description
[0001] The invention relates to a corner connector for joining two plate-shaped elements at an angle – preferably a right angle – with the features of the preamble of claim 1. In particular, the corner connector according to the invention is intended for joining two plate-shaped elements of a piece of furniture or for joining two furniture panels. The plate-shaped elements or furniture panels are, in particular, the sides of a drawer. Furthermore, the invention relates to a corner joint or a piece of furniture with two plate-shaped elements or with two furniture panels, which are connected to each other by the corner connector at a preferably right angle, with the features of the preamble of claim 13 or claim 14.
[0002] Utility model DE 20 2015 006 757 U1 discloses a furniture corner connector for joining two furniture panels at a right angle, comprising an inner L-profile and an outer L-profile that can be interlocked at a distance from each other and parallel to each other, such that the legs of the furniture corner connector are double-walled or form pockets into which the ends of the two furniture panels to be joined can be inserted. The outer surfaces of the legs of the inner L-profile have ribs running parallel to an apex of the L-profile, which engage in grooves in the inner surfaces of the two furniture panels, such that the furniture panels are held against being pulled out of the double-walled legs of the furniture corner connector.
[0003] US Patent 2,133,204 A discloses a corner connector with a right-angled L-profile made of steel, from the inside of one leg of which several smooth-walled, cylindrical pins project at equal intervals from one another in a common plane parallel to the other leg. The known corner connector is attached from below to a base and a wall that rests at a right angle to the base of a cabinet, such that the L-profile rests against the outside of the base and the wall and that the pins engage in holes drilled parallel to the wall through the base into the wall. For securing, screws are driven transversely to the pins of the corner connector through the wall of the cabinet into threaded holes in the pins, passing transversely through the pins of the corner connector. To detach the corner connector for disassembly and removal of the cabinet, the screws are unscrewed, after which the corner connector can be removed from the cabinet.
[0004] To join the walls of a drawer, patent GB 1 341 399 A proposes arranging square-section timbers upright at the corners of the drawer between its walls. Tenons with barbs project from the sides of the timbers facing the drawer walls, engaging in holes in such a way that they connect the drawer walls via the timbers.
[0005] US patent 5,213,403 A discloses a corner connector for drawer walls, which includes a sliding guide for a drawer slide on the underside of a drawer base. The corner connector has an L-shaped profile, one leg of which engages between two abutting drawer walls and from which coaxial pins project on both sides, engaging in holes in the abutting drawer walls. Another leg of the L-shaped profile rests against the outside of one of the drawer walls.
[0006] The object of the invention is to propose a corner connector with which two plate-shaped elements, preferably arranged at a right angle to each other, can be easily connected.
[0007] This problem is solved by the features of claim 1. The dependent claims relate to advantageous embodiments and further developments of the invention.
[0008] The corner connector according to the invention is designed for connecting two plate-shaped, in particular flat, elements that are arranged at an angle to each other, or that are connected at an angle to each other by the corner connector. The plate-shaped elements are, in particular, elements of a piece of furniture and can also be considered furniture panels. The corner connector has a contact surface, in particular a flat surface, for each of the two plate-shaped elements, wherein the two contact surfaces are arranged at an angle of less than 180° and preferably at an angle of 90° to each other. The two contact surfaces of the corner connector according to the invention thus enclose an inside corner with an angle of preferably 90° between them. The two contact surfaces are arranged at the angle to each other at which the two plate-shaped elements are to be arranged and connected to each other.A tenon projects from one of the two contact surfaces, preferably perpendicular to that surface. The inner side of the leg of the L-profile, from which the tenon projects, is referred to here as the first contact surface of the corner connector. Similarly, the leg of the L-profile, from whose inner side the tenon projects, is referred to as the first leg of both the L-profile and the corner connector. To connect the two plate-shaped elements, the corner connector with the tenon is inserted through a through-hole in one of the two plate-shaped elements into a blind hole in the second of the two plate-shaped elements, which is aligned with the through-hole. The first contact surface of the corner connector according to the invention rests against an outer side of the first plate-shaped element, and the second contact surface rests against an outer side of the second plate-shaped element.The pin has barbs on a circumferential surface that counteract or prevent the pin from being pulled out of the blind hole in the second plate-shaped element without damage.
[0009] Preferably, the corner connector according to the invention has more than one pin projecting from the first contact surface. One embodiment of the invention provides three pins, preferably projecting perpendicularly from the first contact surface of the corner connector according to the invention and spaced at different distances from one another. This design prevents the corner connector from being attached to the two plate-shaped elements in a manner other than intended.
[0010] Preferably, the pins are arranged in a common plane that is preferably perpendicular to the first contact surface of the corner connector and / or preferably parallel to the second contact surface of the corner connector.
[0011] In particular, only the first contact surface of the corner connector according to the invention has one or more pins; in this embodiment of the invention, no pin projects from the second contact surface. Specifically, the corner connector has exclusively pins that are parallel to each other.
[0012] One embodiment of the invention provides that the pin(s) do not have a circular cross-section, but rather, for example, an elliptical or oval cross-section. A rectangular cross-section of the pin(s) is also possible. This allows the pin(s) to be inserted into the through hole or blind hole in the plate-shaped elements with less force. A major semi-axis or a major transverse dimension of the cross-section of the pin(s) preferably runs parallel to the second contact surface of the corner connector. This results in the plate-shaped element with the blind hole(s) being subjected to greater stress in its plane than perpendicular to the plane, thereby reducing the risk of the plate-shaped element splitting open.The plate-shaped element with the through-hole(s) is subjected to greater stress parallel to an edge near the blind hole(s) than perpendicular to the edge, which also reduces the risk of the plate-shaped element "bursting open" there.
[0013] A preferred embodiment of the invention provides for a corner connector with a straight L-profile having, for example, strip-shaped legs extending in a longitudinal direction along the L-profile. The inner surfaces of the legs, facing each other, form the two contact surfaces for the two plate-shaped elements to be joined. The two legs of the L-profile, or rather their inner surfaces forming the two contact surfaces, are at a right angle to each other, and the pin(s) extend from one of the inner surfaces, preferably perpendicular and / or parallel to the inner surface of the other leg of the L-profile.
[0014] In one embodiment of the invention, an inner end surface is provided at one end of the two contact surfaces or at one end of the L-profile of the corner connector according to the invention, for example, to support the corner connector on an upper edge of the first plate-shaped element or on the upper edges of both plate-shaped elements. The inner end surface is at – preferably right – angles to the two contact surfaces of the corner connector and extends from one to the other of the two contact surfaces. The inner surface can be understood as a kind of stop or support at one end of the corner connector for contact with the upper edges of the two plate-shaped elements.
[0015] Preferably, the corner connector according to the invention has a plate-shaped end piece at one end, which extends in the inner corner between the contact surfaces of the corner connector from one contact surface to the other. One side of the end piece facing the two contact surfaces forms the inner end surface of the corner connector. The plate-shaped end piece can also be considered as a cover for, for example, the upper edges of the plate-shaped elements to be joined.
[0016] In order to guide a telescopic drawer slide past the corner connector on the underside of the drawer, one embodiment of the invention provides a recess on one of the two legs of the corner connector, extending from an edge furthest from the other leg and the apex. The recess is located, in particular, at one end of the corner connector, specifically at the end furthest from the end piece. Preferably, the recess is located in the leg parallel to the pins. "Recess" means that the leg is narrower in the area of the recess than outside of the recess.
[0017] In order to guide a telescopic drawer slide, which is arranged in a groove in a side wall of the drawer, past the corner connector, one embodiment of the invention has a recess on one of the two legs that extends across the width of the leg and over the apex of the L-profile into the other leg. The recess is preferably provided at a distance from both ends of the corner connector and / or in the leg from which the pins project.
[0018] The corner connector may have a recess and / or a notch.
[0019] Preferably, the corner connector according to the invention is made in one piece; for example, the L-profile with optionally the plate-shaped end piece at one end and the pin(s) projecting from the inner side of one of the two legs of the L-profile forming the first contact surface are manufactured in one piece ("in one shot") by injection molding from plastic.
[0020] Claim 13 relates to a corner joint, in particular of a piece of furniture, comprising two plate-shaped elements or two furniture panels, which are connected to each other by the corner connector according to the invention. The two plate-shaped elements are arranged at an angle to each other – preferably a right angle. The contact surfaces of the corner connector are located on opposite outer surfaces of the two plate-shaped elements. An end face of the second of the two plate-shaped elements rests against an inner surface of the first plate-shaped element at an end or edge of the first plate-shaped element. The end face is a terminal surface at an edge of the plate-shaped element that extends from the inner surface to the outer surface of the plate-shaped element.In the first plate-shaped element, a through-hole is provided for each tenon of the corner connector. This through-hole extends transversely through the first plate-shaped element and aligns with a blind hole located in the end face of the second plate-shaped element. The blind hole(s) are, in particular, parallel to an inner and an outer surface of the second plate-shaped element and open into the end face of the second plate-shaped element, to which the blind hole(s) are, in particular, perpendicular. The two plate-shaped elements are connected by the tenon(s) of the corner connector being inserted through the through-hole(s) in the first plate-shaped element into the blind hole(s) in the end face of the second plate-shaped element. Additionally, the bearing surfaces of the corner connector hold the two plate-shaped elements together.The barbs on the corner connector's pins – if present – prevent it from being pulled out of the blind hole(s) in the second plate-shaped element, thus improving the corner connector's hold on the two plate-shaped elements and consequently the connection between them. The plate-shaped end piece covers the upper edge of the first plate-shaped element, or the upper edges of both plate-shaped elements, or the edges of the plate-shaped elements adjoining the corner.
[0021] According to the invention, the barbs are located outside a region of the pin(s) that extends along the pin(s) from the leg of the corner connector from which the pin(s) project at least as far as the other leg of the corner connector is wide. Here, the width is the extent of the other leg transverse to the apex and parallel to the pin(s). This design enables or facilitates demolding of the corner connector from an injection mold after injection molding.
[0022] In order to avoid trough-shaped depressions in an outer side of the leg of the corner connector, from the inside of which the pin(s) protrude, when manufacturing the corner connector by injection molding from plastic, the pin(s) in a preferred embodiment of the invention are tubular hollow pins.
[0023] The piece of furniture is in particular a drawer with a side wall and a back wall, which form the two plate-shaped elements that are connected with the corner connector according to the invention.
[0024] All features mentioned in the description and / or illustrated in the drawing can be implemented individually or in any combination in embodiments of the invention. Embodiments of the invention that do not include all, but only some, of the features of a claim, including an independent claim, are possible.
[0025] The invention is explained in more detail below with reference to an embodiment illustrated in the drawing. The drawing shows: Figure 1 shows a corner connector according to the invention in a perspective view; Figure 2 shows an exploded view of a corner joint with the corner connector made of Figure 1 according to the invention; Figure 3 the corner joint made of Figure 2from an outside in a perspective view; Figure 4 the corner joint made of Figures 2 and 3 from an interior view in a perspective representation; and Figure 5, an end view of a tenon of the corner connector made of Figure 1 .
[0026] The in Figure 1The corner connector 1 according to the invention, as illustrated, has a straight L-profile 2 with two strip-shaped legs 3, which – in the exemplary embodiment – are arranged at an angle of 90° to each other. The strip-shaped legs 3 – in the exemplary embodiment – extend parallel to a vertex 4 of the L-profile, with the legs 3 seamlessly merging into one another at their longitudinal edges facing each other at the vertex 4 of the L-profile 2 of the corner connector 1. The longitudinal direction of the legs 3 of the corner connector 1 is here defined as the direction parallel to the vertex 4 of the L-profile 2, regardless of whether the legs 3 are longer in this direction than perpendicular to the vertex 4. Correspondingly, the longitudinal edges of the legs 3 are defined as the edges of the legs 3 of the corner connector 1 that are parallel to the vertex 4 of the L-profile 2.
[0027] The opposing sides of the legs 3 of the corner connector 1 according to the invention, which have an internal angle between them which in the exemplary embodiment is 90°, form two contact surfaces 5, 6 for two plate-shaped elements 7, 8 ( Figures 2 to 4The corner connector 1 connects the two surfaces 5, which are joined to each other at an angle of 90° in the exemplary embodiment. One of the two contact surfaces 5, referred to here as the first contact surface 5, has three pins 9 arranged in a plane perpendicular to the first contact surface 5 and parallel to the apex 4 of the L-profile 2 of the corner connector 1, and in a plane parallel to a second of the two contact surfaces 6 of the corner connector 1. The pins 9 are spaced at different distances from each other. The number of three pins 9, their arrangement in a common plane, and their different distances from each other are not essential to the invention. At least two pins 9 are provided, and more than three pins 9 are also possible. The invention does not preclude an embodiment of the corner connector 1 with only one pin 9.
[0028] The corner connector 1 has exclusively parallel pins 9 that project from the first contact surface 5. The second contact surface 6 has no pins 9. In the exemplary embodiment, the pins 9 are located in a common plane.
[0029] The pins 9 have sawtooth-shaped barbs 10 around their circumference, which are directed towards the first contact surface 5. In the exemplary embodiment, the barbs 10 are distributed evenly around the circumference of the pins 9 and arranged along a portion of the length of the pins 9, starting at the free ends furthest from the first contact surface 5.
[0030] In a longitudinal area extending from the leg 3 of the corner connector 1, from which the pins 9 protrude, at least as far as the other leg is wide perpendicular to the apex 4 of the L-profile 2 of the corner connector 1 and parallel to the pins 9, the pins 9 do not have barbs 10 in order to be able to demold the corner connector 1 from an injection molding tool after injection molding in plastic.
[0031] In the exemplary embodiment, the tenons are 9 tubular hollow tenons (see figure). Figure 1 ), so that no trough-shaped depressions form in an outer side of the leg 3 during injection molding of the corner connector 1, from whose inner side the pins 9 protrude.
[0032] At one end of the L-profile 2, the corner connector 1 has a plate-shaped end piece 11, the side of which facing the legs 3 forms an inner end surface 12 of the L-profile 2 of the corner connector 1, which extends in the inner angle between the two contact surfaces 5, 6 of the L-profile 2 of the corner connector 1 according to the invention. The plate-shaped end piece 11, or the inner end surface 12, is at an angle – in the exemplary embodiment at a right angle – to the L-profile 2, or to the two legs 3 of the corner connector 1.
[0033] As in Figure 1 and 3As can be seen, one of the two legs 3 of the corner connector 1 according to the invention has a recess 27 on or in a longitudinal edge parallel to the apex 4, located furthest from the other leg 3 and the apex 4. In the area of the recess 27, the leg 3 is narrower than outside the recess 27. In the embodiment shown, the recess 27 is located at an end of the corner connector 1 furthest from the end piece 11 and on the leg 3 that is parallel to the pins 9. The recess 27 allows the passage of a telescopic rail (not shown) for extending a drawer 15 (to be explained later), which is arranged on the underside of the drawer 15. The telescopic rail passes through the recess 27 on the leg 3 of the corner connector. As shown in Figure 3 Preferably, a back panel 14 of the drawer 15 in the area of the recess 27 of the corner connector 1 is also recessed.
[0034] As in Figures 2 and 3As can be seen, one of the two legs 3 of the corner connector 1 according to the invention has a recess 28 that extends across the width of the leg 3 and over the apex 4 of the L-profile 2 of the corner connector 1 into the other leg 3. The recess 28 is located in a central area of the corner connector 1 between the two ends of the corner connector 1. The recess 28 allows the passage of the telescopic rail of the drawer 15 (not shown) when the telescopic rail is arranged on the outside of a side wall 13 of the drawer 15. Figure 3 The side wall 13 of the drawer 15 has a groove 28 on its outer side in which the telescopic rail (not shown) is or will be arranged.
[0035] In the exemplary embodiment, leg 3 has the recess 28, from the inside of which the pins 9 project. Thus, one leg 3 has the recess 27 and preferably the other leg 3 has the recess 28.
[0036] The corner connector 1 can have the recess 27 and / or the recess 28. Versions that have neither the recess 27 nor the recess 28 are also possible.
[0037] In the exemplary embodiment, the corner connector 1 according to the invention, with its L-profile 2, the pins 9 and the plate-shaped end piece 11, is manufactured in one piece by injection molding from plastic.
[0038] The corner connector 1 is designed to connect the two plate-shaped elements 7, 8 at the angle that the two legs 3 of the L-profile 2 of the corner connector 1 have to each other, in the exemplary embodiment therefore at an angle of 90° to each other. In particular, the corner connector 1 is designed to connect two plate-shaped elements 7, 8 of a piece of furniture, whereby the plate-shaped elements 7, 8 can also be referred to as furniture panels in this case. In the embodiment shown in Figures 2 to 4In the illustrated embodiment of the invention, the corner connector 1 connects a side wall 13 with a back wall 14 of a piece of furniture, which in this embodiment is a drawer 15 (not shown). The side wall 13 forms the first plate-shaped element 7, the back wall 14 the second plate-shaped element 8, and the drawer 15 the piece of furniture.
[0039] For connection purposes, three through holes 16 are provided in one of the two plate-shaped elements 7, and three blind holes 17 are provided in the other of the two plate-shaped elements 8. In the exemplary embodiment, the through holes 16 are provided in the first plate-shaped element 7 and in the side wall 13, respectively. The through holes 16 are located at a distance from an end edge 18 of the plate-shaped element 7 that is equal to the distance between the pins 9 of the corner connector 1 and the second contact surface 6 of the L-profile 2 of the corner connector 1. The through holes 16 are spaced the same distance apart as the pins 9, and a first through hole 5 is located at a distance from an upper edge 19 of the plate-shaped element 7 that is equal to the distance between a pin 9 nearest the inner end surface 12 of the corner connector 1 and the inner end surface 12.The front edge 18 is here referred to as an edge facing the corner connector 1 and the upper edge 19 as an edge of the plate-shaped element 7 facing the end piece 11.
[0040] The three blind holes 17 are provided in an end face 20 of the other plate-shaped element 8, in this case the second plate-shaped element 8, which in the exemplary embodiment forms the back panel 14 of the drawer 15. The end face 20 is an end face on the end edge of the second plate-shaped element 8 facing the first plate-shaped element 7 and the corner connector 1. The three blind holes 17 are provided at a distance from an outer surface 21 of the second plate-shaped element 8 that is equal to the distance of the pins 19 from the second contact surface 6 of the corner connector 1. The distance between the three blind holes 17 is as large as the distance between the tenons 19 and the distance between a blind hole 17 and the upper edge 22 of the plate-shaped element 8 is as large as the distance between the tenon 9 of the corner connector 1 and the inner end surface 12.The blind holes 17 are arranged parallel to the outer surface 21 and the upper edge 22 of the plate-shaped element 8. The outer surface 21 is defined as the side of the second plate-shaped element 8 facing away from the first plate-shaped element 7.
[0041] To connect them, the two plate-shaped elements 7, 8 are arranged at a right angle to each other such that the end face 20 of the second plate-shaped element 8 abuts an inner surface 23 facing it of the first plate-shaped element 7, and the blind holes 17 in the end face 20 of the second plate-shaped element 8 are aligned with the through holes 16 that extend transversely through the first plate-shaped element 7 along its end face 18. The corner connector 1 is inserted with its pins 9 through the through holes 16 in the first plate-shaped element 7 and into the blind holes 17 in the second plate-shaped element 8 until the first bearing surface 5 of the L-profile of the corner connector 1 abuts an outer surface of the first plate-shaped element 7.The second contact surface 6 lies against the outside 21 of the second plate-shaped element 8 and the inner end surface 12 of the plate-shaped end piece 11 of the corner connector 1 lies against the upper edges 19, 22 of the plate-shaped elements 7, 8.
[0042] The barbs 10 of the pins 9 hold the pins 9 in the blind holes 17 of the second plate-shaped element 8 and prevent them from being pulled out of the blind holes 17. The diameters of the through holes 16 and the blind holes 17 can be selected and the barbs 10 designed such that the pins 9 can be pulled out of the blind holes 17 and the through holes 16 without damage to loosen the connection, or such that the pins 9 cannot be pulled out of the blind holes 17 of the second plate-shaped element 8 without damage if loosening the connection is to be avoided.
[0043] The corner connector 1, which connects the two plate-shaped elements 7, 8 with its contact surfaces 5, 6 and the pins 9, and the two plate-shaped elements 7, 8 form a corner connection 24 according to the invention.
[0044] On their inner surfaces 23, the two plate-shaped elements 7, 8, which form the side wall 13 and the back wall 14 of the drawer 15, have grooves 25 that run parallel to the lower edges opposite the upper edges 22. A base 26 of the drawer 15 is inserted into the grooves 25.
[0045] The cones 9 can have circular cross-sections. Figure 5Figure 1 shows one of the pins 9 with a round, but not circular rather elliptical, cross-section, whereby a larger semi-axis, i.e., a largest transverse dimension of the pins 9, runs parallel to the second contact surface 6. An oval cross-section of the pins 9 is also possible, for example. The elliptical or oval cross-section, or in any case the non-circular cross-section, facilitates the insertion of the pins 9 through the through holes 16 in the first plate-shaped element 7 and the insertion of the pins 9 into the blind holes 17 in the second plate-shaped element 8.By aligning the largest transverse dimension of the pins 9 parallel to the second contact surface 6, the first plate-shaped element 7 is subjected to greater stress by the pins 9 of the corner connector 1 inserted through its through holes 16, parallel to an edge near the through holes 18, than perpendicular to the edge. Similarly, the second plate-shaped element 8 is subjected to greater stress in its plane than perpendicular to the plane of the plate by the pins 9 of the corner connector 1 inserted into its blind holes 17. Both of these factors reduce the risk of the plate-shaped elements 7 and 8 splitting open.
