DETAILED DESCRIPTION OF THE INVENTION

[0010] The mounting element 1 shown in FIGS. 1a to 1f is intended to connect furniture elements with different orientations. The mounting element 1 has an elongated body 2 that is cubic in at least some parts. The body 2 has a longitudinal axis 3, four parallel longitudinal faces 4a to 4d in pairs, and two longitudinal ends 5a, 5b. At least one of the four longitudinal faces 4a to 4d forms a planar fastening surface by which the mounting element 1 can abut and fasten to a furniture element. In the illustrated exemplary embodiment, all four longitudinal faces 4a to 4d form planar fastening surfaces by which the mounting element 1 can be fastened to a furniture element. For this purpose, each longitudinal face of the body 2 that forms the fastening surface is provided with one or more through-holes 6 (e.g., two, spaced 32 mm apart).

[0011] As shown in FIGS. 1e and 1f, the body 2 has a dashed square 7 contour with edges of length D when viewed in the direction of the longitudinal axis 3.

[0012] The body 2 has a first mounting surface 8a at one of its first longitudinal ends 5a and a second mounting surface 8b at its other, second longitudinal end 5b, both of which are formed by stepped portions of the body 2. The first mounting surface 8a is arranged parallel to the longitudinal faces 4a, 4d and perpendicular to the longitudinal faces 4b, 4c. The second mounting surface 8b is inclined relative to the longitudinal faces 4a-4d by 45° about the longitudinal axis 3, in this case by way of example only. The first and second mounting surfaces 8a, 8b are arranged rotated by 45° relative to each other about the longitudinal axis 3, such that the longitudinal axis 3 of the body 2 lies in the plane of the first and second mounting surfaces 8a, 8b.

[0013] The rear surface of the first longitudinal end 5a, facing the first mounting surface 8a, is formed by a longitudinal surface 4d parallel to the first mounting surface 8a. Meanwhile, the rear surface of the second longitudinal end 5b, facing the second mounting surface 8b, is formed by an independent rear surface 9 parallel to the second mounting surface 8b. The thickness of the longitudinal ends 5a, 5b, i.e., the distance between the first mounting surface 8a and the longitudinal surface 4d in the case of the first longitudinal end 5a, and the distance between the second mounting surface 8b and the rear surface 9 in the case of the second longitudinal end 5b, corresponds to half the edge length D of the main body 2, i.e., D / 2 (FIG. 1c). When viewed along the longitudinal axis 3, each of the longitudinal ends 5a, 5b has an inner portion 10 whose width is equal to the edge length D of the main body 2 (FIG. 1e), and the outer portion 11 adjacent to it has a rounded front surface.

[0014] Furthermore, the body 2 also has, between its two longitudinal ends 5a, 5b, preferably centrally, a third mounting surface 8c formed by the groove base of a transverse groove 12, said transverse groove being open on both sides and arranged parallel to the longitudinal faces 4a, 4d and perpendicular to the longitudinal faces 4b, 4c. The first and third mounting surfaces 8a, 8c are arranged in the same plane, and the longitudinal axis 3 also lies in the plane of the third mounting surface 8c. The groove width of the transverse groove 12 in the direction of the longitudinal axis 3 and the groove length of the transverse groove 12 in the direction transverse to the longitudinal axis 3 are the same length as the edge length D.

[0015] One of the two groove walls of the transverse groove 12 is formed by a spring element 13, which is connected to the groove bottom and has a locking element 14 on its free end, which here has, for example, a convex cross-sectional shape extending transversely to the longitudinal axis 3. The body 2 has, on one of its two longitudinal faces 4b, 4c, the face (4c) on which the transverse groove 11 opens transversely to the longitudinal axis 3, a locking element 15, which has a shape complementary to the locking element 14 of the spring element 13 and here has, for example, a concave cross-sectional shape extending along the entire longitudinal face 4c.

[0016] The first, second, and third mounting surfaces 8a-8c all have the same locking arrangement consisting of multiple locking elements arranged around a center, such as locking protrusions 16 and locking recesses 17. The locking arrangement has multi-fold rotational symmetry about the center, and in this case, it is a circular arrangement, and the locking protrusions 16 and locking recesses 17 are arranged alternately on the circumference at 45° intervals, resulting in four-fold rotational symmetry. The center of the locking arrangement is determined by the through-hole 18 in each mounting surface 8a-8c.

[0017] The body 2 also has a fourth mounting surface 8d formed by a longitudinal surface 4d, and when viewed from the side has a comb-shaped cross-section 19. The comb-shaped cross-section 19 has alternating high and low comb-step portions 20a and 20b, all of which have the same cross-sectional width.

[0018] 2a to 2f show a connector 21 comprising two or three mounting parts 1 abutting against each other by means of first, second or third mounting surfaces 8a to 8c and connected to each other by screws 22 as required.

[0019] In Figure 2a, two mounting parts 1 are arranged with their longitudinal axes 3 oriented at right angles to one another and abutting each other at their first mounting surfaces 8a.

[0020] In Figure 2b, two mounting parts 1 are oriented with their longitudinal axes 3 at an angle of 135° to each other and abut against each other with their first mounting surfaces 8a.

[0021] In Figure 2c, the two mounting parts 1 are arranged with their longitudinal axes 3 at right angles to each other and abut against each other at the first and second mounting surfaces 8a, 8b.

[0022] In Figure 2d, the three mounting parts 1 are oriented with their longitudinal axes 3 oriented in a zigzag pattern relative to one another. In Figure 2d, the upper and middle mounting parts 1 are oriented with their longitudinal axes 3 oriented at right angles to one another and abut each other at their first mounting surfaces 8a, 8a. The lower and middle mounting parts 1 are oriented with their longitudinal axes 3 oriented at 135° to one another and abut each other at their first and second mounting surfaces 8a, 8b.

[0023] In Figure 2e, two mounting parts 1 are arranged with their longitudinal axes 3 oriented perpendicular to each other and abutting each other at the first and third mounting surfaces 8a, 8c. The protrusion 14 of the spring member 13 of one mounting part 1 engages with the recess 15 of the other mounting part 1, thereby locking the two mounting parts 1 together.

[0024] In Fig. 2f, the two mounting parts 1 are oriented with their longitudinal axes 3 at right angles to one another and abut against one another on the third mounting surfaces 8c, 8c by the lateral grooves 12 of the two mounting parts 1, which are oriented rotated 90° relative to one another and interdigitated. On the one hand, the protrusion 14 of the spring element 13 of the lower mounting part 1 in Fig. 2f engages with the recess 15 of the upper mounting part 1, and on the other hand, the protrusion 14 of the spring element 13 of the upper mounting part 1 engages behind or below the lower step 20b of the longitudinal surface 4d of the lower mounting part 1, thereby doubly locking the two mounting parts 1 against one another.

[0025] 2a to 2f, the locking projections 16 and the locking recesses 17 of the mounting surfaces that abut against each other in a desired angular direction are engaged with each other. Screws 22 are threaded through the through holes 18 of the abutting mounting surfaces, thereby fixing the mounting surfaces, and thus the two mounting parts 1, in the locked angular direction.

[0026] FIG. 3 shows a connector 21 including two mounting parts 1 whose longitudinal axes 3 are parallel to one another and whose longitudinal surfaces 4a are inserted into one another. The longitudinal surface 4a of each mounting part 1 has a comb-shaped insertion cross-section, consisting of a first mounting surface 8a recessed by a step and a lateral groove 12 whose bottom surface is flush with the first mounting surface 8a. The two mounting parts 1 are inserted into one another via this comb-shaped insertion cross-section. A protrusion 14 on a spring member 13 of one mounting part engages with a locking recess 23 (FIG. 1c) on the other mounting part. This locking recess 23 is located in front of the step between the first mounting surface 8a and the longitudinal surface 4a, thereby doubly locking the two mounting parts 1. To fasten the two mounting parts 1 together, a fastening screw 22 can be threaded into the through holes 6, 18. This connector 21 can be used, for example, as a double connector for two furniture panels.

[0027] FIG. 4 shows a connector 21 including two mounting parts 1 oriented with their longitudinal axes 3 parallel to one another and with their comb-shaped mounting surfaces 8d engaging each other. The high comb step portion 20a of one mounting part 1 engages with the low comb step portion 20b of the other mounting part 1. As shown in FIGS. 5a-5c, the mounting parts 1 can be offset by different lateral offset amounts: 0 mm (FIG. 5a), 4 mm (FIG. 5b), or 8 mm (FIG. 5c), depending on which high comb step portion 20a and which low comb step portion 20b engage each other. To achieve a 4 mm lateral offset, in FIG. 5b, the lower mounting part 1 is laterally flipped or rotated 180° compared to FIGS. 5a and 5c.

[0028] The lateral groove 12 can be open on only one lateral side instead of both lateral sides as shown in the exemplary embodiment. The body can also have a rectangular or polygonal outer contour when viewed in the direction of the longitudinal axis 3 instead of the square 7 shown in the exemplary embodiment. The body 2 can also have fewer longitudinal sides, i.e., for example, only one, two, or three, instead of the four longitudinal sides 4a-4d shown in the exemplary embodiment. The body 2 can also have fewer mounting surfaces, i.e., for example, only one, two, or three, instead of the four mounting surfaces 8a, 8b shown in the exemplary embodiment. Also, instead of being screwed, the fastening surfaces of the mounting part 1 can be adhesively bonded to the part.

[0029] Furthermore, a corner connection between two parts can be made using only one mounting part 1 by screwing two orthogonally arranged longitudinal faces to the part respectively.

[0030] 1 to 5 do not show the components fastened to each mounting component 1. The components can be oriented, for example, at 45°, 90°, 135°, or 180° to each other, or can be connected in a T-shape.

[0031] 6a and 6b show a furniture assembly 30 in which two panel-like furniture parts 31, 32 are arranged at right angles to each other and connected to each other by a connector 21. As shown in FIG. 6a, the longitudinal surfaces 4a of one first mounting part 1 and the other second mounting part 1 are screwed to the other first furniture part 31 or the other second furniture part 32 by screws 33 passing through the through-holes 6. The furniture parts 31, 32 are then moved, with the longitudinal axes 3 of the two mounting parts 1 aligned parallel to each other, until the inclined second mounting surfaces 8b of the two mounting parts 1 abut each other and are locked together by the locking elements 16, 17 (FIG. 6b). The second mounting surfaces 8b then engage beneath each other, thereby securing the two furniture parts 31, 32 to each other. Overall, this provides a highly rigid and strong corner connection.

[0032] 7a and 7b show a furniture assembly 30 including two furniture parts 31 and 32, with a gap dimension s adjusted to 4 mm by connectors 21. Each mounting part 1 has its longitudinal surface 4c screwed to the panel side of the furniture parts 31 and 32. The lower mounting part 1 in FIG. 7 protrudes upward beyond the upper edge of the lower furniture part 31, and the upper mounting part 1 protrudes downward beyond the lower edge of the lower furniture part 31; that is, the total protrusion amount corresponds to the gap dimension s. The two furniture parts 31 and 32 are first positioned with their front faces facing each other and with their mounting parts 1 facing each other, i.e., at an angle (FIG. 7a). Next, the two mounting parts 31 and 32 are rotated to their flush mounting positions, whereby the high comb-shaped step portions 20a and low comb-shaped step portions 20b of the two mounting parts 31 and 32 engage with each other, as shown in FIG. 5a (FIG. 7b). The pivot axis is defined by these fitting parts 1 engaging with each other.

[0033] FIG. 8 shows a furniture assembly 30 consisting of three furniture parts 31, 32, and 33, in which the central furniture part 32 is fastened to the other two furniture parts by two connectors 21. The two lower connectors 21 are arranged as shown in FIG. 7, and the two upper connectors 21 are arranged as shown in FIG. 2e and fastened to the respective furniture parts. First, as shown in FIG. 7a, the central furniture part 32 is placed diagonally on the lower furniture part 31 using the two lower connectors 21. Then, the central furniture part 32 is rotated to a flush mounting position with the other two furniture parts 31 and 33, thereby locking the two mounting parts 1 of the upper connectors 21 together. The mounting parts 1 of the connectors 21 can then be fastened to each other by screws 22. [Explanation of symbols]
