Description

Connecting element for plates

The present invention relates to a connecting element for plates, in particular for kitchen worktops, with a first fastening element, which can be fixed to a first plate, and a second fastening element, which can be secured to a second plate, wherein the fastening elements are connected to one another via a movable Führungsseiement.

DE 32 36 719 discloses a clamping connector for profile afford, which is introduced into two adjacent holes in the profile strips. The clamp connector comprises two insertion body, wherein an insert body engages with a connecting strap in the other insert body and there is adjustable via an eccentric and can be fixed. Especially in the assembly of countertops, for example, for kitchens, a precise alignment and adjustment is often required so that the adjacent plate parts are exactly aligned and form a flat surface. Such Justagemöglichkeit is not available in this clamp connector.

It is therefore an object of the present invention to provide a connector for plates, which allows easy alignment of the plates to each other in different directions.

This object is achieved with a connecting element for plates having the features of claim 1.

According to the invention, an eccentric for moving the guide element is rotatably mounted on each fastening element, wherein a first eccentric can move the guide element in a first direction and a second eccentric the guide element in a deviating from the first direction second direction. Thereby, the fasteners connectable to the plates can be moved relative to each other in different directions to align the plates. This can also be done after a pre-assembly of the plates, so that over the connecting element a fine division can be made. The eccentrics can thereby move the guide element in different directions, in particular at right angles to each other, so that a simple tolerance adjustment is possible.

For a compact design, the guide element is preferably plate-shaped. The guide element can each partially in one , -

Recording to be received on the first and the second fastening element, so that the guide element between the fastening element and a plate is slidably disposed. According to a further embodiment, two obliquely aligned slots are formed on the guide element, which are each penetrated by an eccentric. The eccentric is rotatably mounted on a circular opening of a fastening element, so that a pin of the eccentric is guided in the slot to move the guide element.

Further, elongated holes can be formed on the guide element in an advantageous manner, which are penetrated to guide the relative movement between the guide element and a fastening element in each case by a bolt. As a result, higher forces can be absorbed by the connecting element, wherein in each fastener more than one bolt can be set to increase the stability.

The connecting element can be mounted in a simple manner on a bore of two adjacent plates, if the fastening elements are designed as semicircular plates. Then, the center of the bore is arranged approximately in the region of the parting plane and on each plate, a semicircular plate can be mounted as a fastener.

The guide element is preferably plate-shaped and T-shaped. In this case, the guide element can be inserted into a rectangular receptacle on the two fastening elements, with individual side edges of the receptacle forming guide surfaces for a displacement of the guide element relative to the fastening elements. The guide element is thus partially positively inserted into the receptacle on the fastening elements. For a stable guidance, the guide element and the fastening elements can each be made of a metal sheet.

According to the invention, a plate arrangement is provided with a corresponding connecting element, wherein the fastening elements are preferably each screwed to a plate. A pot bore is not required for the use of the connecting element according to the invention, but is advantageous. - -

The receptacle for the connecting element in the divided plate may also be formed as a long recess or opening, which is divided in the longitudinal direction by the joint. In each panel connected to the half of the slot is e.g. executed as a milling. Half of the elongated hole corresponds approximately to the radius of the connecting element. The depth of the elongated hole preferably corresponds to the thickness of the connecting element.

The invention will be explained in more detail below with reference to an exemplary embodiment with reference to the accompanying drawings. Show it:

Figure 2 is a perspective view of a mounted connecting element;

FIGS. 3A and 3B show two perspective views of the connecting element during the adjustment;

Figure 4 is an exploded perspective view of the connecting element;

FIGS. 5A and 5B show two views of the preassembled connecting element, and FIGS

FIGS. 6A to 6C show several views of the preassembled connecting element.

A connecting element 1 serves to connect two adjacent plates 2 and 3, for example, to form a common kitchen worktop, wherein at a joint 8 between the plates 2 and 3, a bore is introduced and a half-bore 6 to the plate 2 and a half-bore 7 on the plate 3 is omitted.

The connecting element 1 comprises a first fastening element 4, which is designed as a semicircular plate and can be inserted via screws 9 into the drilling half 6. On the opposite side, the second fastening element 5 is also formed as a semicircular plate and can in the - -

Drill half 7 are inserted so that the mounting position shown in Figure 2 is achieved.

The union union 1 can make an alignment of the plates 2 and 3 relative to each other, as shown in Figures 3A and 3B. On the first fastening element 4, a rotatable eccentric 11 is arranged, while on the second fastening element 5, a second eccentric 12 is provided. By turning the second eccentric 2 by a screwdriver 10, the plates 2 and 3 can be displaced perpendicular to the plane of the end edges at the joint 8 relative to each other, as shown by the arrows. Similarly, by turning the first eccentric 11 through the screwdriver 10, an adjustment movement can be made parallel to the plane of the end edges on the joint 8, as shown schematically by the arrows in FIG. 3B.

In Figure 4, the Verbindungsseiement is shown with all items. In the first fastening element 4, a larger circular opening 13 is arranged for the rotatable mounting of the eccentric 1, which has a pin spaced from the axis of rotation, which engages through a slot 22 on a guide element 20. On the second fastening element 5, an opening 14 for rotatably supporting the second eccentric 12 is formed in a similar manner, which has an eccentric to the axis of rotation arranged pin, which passes through a slot 21. The guide member 20 is plate-shaped and has a substantially T-shape with a narrower and a wider portion. The guide element 20 is displaceably mounted relative to the fastening elements 4 and 5. For this purpose, 20 elongated holes 23 are formed in the narrower portion of the guide member, which are aligned parallel to the joint 8 and the end edges of the plates 2 and 3, while at the wider portion of the guide member 20 slots 24 perpendicular to the plane of the end faces of the plates 2 and 3 are aligned. The elongated holes 23 and 24 are each penetrated by bolts 16, which are arranged on circular openings 15 on the fastening elements 4 and 5. The bolts 16 may be formed as rivets, which are captively fixed to the fastening elements 4 and 5. Furthermore, the screws 9 are still shown, by means of which the Befestigungsseiemente 4 and 5 can be fixed to the plates 2 and 3. - -

In FIGS. 5A and 5B, the connecting element 1 is shown in the preassembled position without the plates 2 and 3. The plate-shaped guide element 20 is arranged in a rectangular recess 30 on the fastening elements 4 and 5, wherein the wider portion of the guide element 20 rests against side edges of the recess 30. If the first eccentric 11 is rotated, the guide element 20 shifts under the guidance of the bolts 16 in the oblong holes 23 according to FIG. 3A. If the second eccentric 12 is rotated, the guide element 20 shifts as shown in FIG. 3B.

In FIGS. 6A to 6C, the connecting element is shown in detail. As can be seen in particular in FIG. 6C, side edges 27 of the wider section of the guide element 20 bear against the side edges of the recess 30 and form a guide surface for the displacement movement. A side edge 25 between the two side edges 27, however, is spaced from an edge of the receptacle 30, so that in this direction, the guide member 20 in the receptacle 30 is displaceable. On the opposite side on the narrower section of the guide element 20, side edges 28 are each arranged at a distance from one another to form an edge of the receptacle 30, so that a sliding movement is made possible here. An end edge 26 between the two side edges 28, however, abuts against a side edge of the receptacle 30, so that here a guide surface for the displacement movement is provided. In order to securely fix the fastening elements 4 and 5 to the plates 2 and 3, embossments 7 are further formed which dig into the material of the plates 2 and 3 during screwing. The fastening elements 4 and 5 are preferably formed of sheet metal by punching and embossing, as well as the guide member 20. But other materials, such as plastic, can be used.
