Description

The invention relates to an assembly unit for connecting a lid to a connection arrangement which can be pivotably connected to a swivel arm.

From the EP 3 460 154 A1 a connection arrangement for pivotally connecting a support arm to a cover is known. The connection arrangement comprises a connection element which can be connected to the cover, wherein it lies directly on the cover.

The object of the present invention is to provide a mounting unit for connecting a cover to a connecting arrangement which can be pivotably connected to a swivel arm, and which can be mounted simply and reliably. Furthermore, it is an object of the present invention to provide a coupling arrangement for the pivotable coupling of a pivot arm to a cover, which is also simple and reliable to assemble.

The object is achieved by an assembly unit for connecting a lid to a connection arrangement which can be pivotably connected to a swivel arm, comprising: a first fastening element and a second fastening element, each having a thread with which they can be fastened to the lid, and a mounting element with a first opening in which the first fastening element is seated in a preassembled state and with a second opening in which the second fastening element is seated in the preassembled state.

Because the first fastening element and the second fastening element are pre-assembled in the first and second opening of the assembly element, they are secured to the assembly element in such a way that they are not isolated during assembly and can therefore be lost. In addition, the two fastening elements are positioned exactly relative to the cover with which they can be connected, so that in particular an oblique screwing in is prevented.

At least one of the first and second fastening elements can have a guide section, a head section and a threaded section. At least one of the first and the second fastening element can be made in one piece.

The first opening can form a counter thread to the thread of the first fastening element, and / or the second opening can form a counter thread to the thread of the second fastening element.

The first opening can delimit an inner cylinder, the diameter of which is smaller than a nominal diameter of the thread of the first fastening element, and / or the second opening can delimit an inner cylinder, the diameter of which is smaller than a nominal diameter of the thread of the second fastening element. In the sense of the present invention, an inner cylinder is to be understood as an imaginary cylinder which touches the surface delimiting the opening or the surfaces delimiting the opening, but does not penetrate it. In other words, the inner cylinder is the largest imaginary cylinder that can be placed entirely in the opening.

The thread of the first fastening element can have an axial spacing of two opposite flanks on a diameter that corresponds to the diameter of the inner cylinder of the first opening, which is at least twice as large as a thickness of the mounting element. As a result of this configuration, a cylindrically designed first opening also forms a counter thread to the thread of the first fastening element, the counter thread being a thread without a pitch.

Alternatively, the first opening and / or the second opening can have a thread in the form of a profiled notch. The indentation can either have been made in the opening by means of a thread cutting tool or can be made in the opening by means of self-tapping first fastening elements or second fastening elements.

The thread of the second fastening element can have an axial spacing of two opposite flanks on a diameter that corresponds to the diameter of the inner cylinder of the second opening, which is at least twice as large as a thickness of the mounting element. As a result of this configuration, a cylindrically designed second opening also forms a counter thread to the thread of the second fastening element, the counter thread being a thread without a pitch.

The inner cylinder of the first opening and / or the inner cylinder of the second opening can have a diameter which is smaller than the diameter of the guide section of the first or of the second fastening element. As a result, the guide section comes into contact with the mounting element when the fastening elements are connected to the cover. The assembly force is thus even and over the assembly element introduced into the lid over a large area, so that the fastening elements do not sink into the lid. In particular, damage to the cover can be prevented if the connecting force of the fastening elements is selected incorrectly.

The mounting element can comprise a first insert element which has the first opening and a second insert element which has the second opening. The first and / or the second insert element can in particular be made of a plastic. The first insert element can be inserted, in particular clipped, into a first receiving opening of a mounting element of the mounting element. The second insert element can be inserted, in particular clipped, into a second receiving opening of the mounting element.

At least one of the first and second insert elements can be configured as an expansion element. By screwing the thread of the first fastening element or the second fastening element into the first insert element or the second insert element, the effective diameter of the expansion element is increased, so that the expansion element can be clamped in a receptacle, for example a fastening hole in the cover.

The object is further achieved by a coupling arrangement for pivotably coupling a swivel arm to a cover, comprising: a connection arrangement which can be pivotably connected to the swivel arm, an assembly unit according to a previously mentioned embodiment which can be fastened to the cover, the first fastening element and the second fastening element of the assembly unit is connected to the connecting arrangement in the assembled state of the coupling arrangement.

The connection arrangement can in particular be a single connection element.

At least one of the first and the second fastening element can have a guide section and a head section, and the connecting arrangement can have a guide slot, with which it is slid onto the guide section in an assembled state of the coupling arrangement in a mounting direction, the connecting arrangement having the head section in a Direction reaches behind to the direction of assembly. The at least one of the first and the second fastening element can comprise a ring element which has the guide section and the head section, and a thread element which has the thread and which is inserted into the ring element.

The 1 to 6 , which are described below together, show a cover fitting 1 with an assembly unit according to the invention 36 , The lid fitting 1 has a base element 2 on, the fastening screws, not shown, on a furniture body 6 is attached. The basic element 2 is therefore on the side wall 5 of the furniture body 6 fixed.

On the base element 2 is a swivel arm 7 around a first body axis K1 pivotally attached. On one of the first cabinet axis K1 far end is the swivel arm 7 with a connecting element 8th around a first lid axis D1 pivotally connected. The first body axis K1 and the first lid axis D1 are spaced apart and arranged parallel to each other.

The lid 11 is only via the cover fitting 1 or other comparable cover fittings with the furniture body 6 pivotally connected. No further hinges are provided.

A defined movement of the lid 11 opposite the furniture body 6 to ensure the cover fitting 1 in the present embodiment, a control arm 12 on that on the base element 2 around a second body axis K2 is pivotally connected and on the connecting element 8th around a second lid axis D2 is pivotally connected. The second body axis K2 and the second lid axis D2 are spaced and parallel to each other and spaced and parallel to the first body axis K1 and first lid axis D1 arranged. Thus form the swivel arm 7 and the control arm 12 a parallelogram arrangement that defines a defined sequence of movements of the lid 11 pretends.

The lid 11 can be compared to the furniture body 6 by means of the cover fitting 1 between one in 1 shown open position and a closed position move, the lid 11 is arranged in the closed position in a vertical position and an opening 26 of the furniture body 6 closes.

The connecting element 8th is with a first fastener 9 and a second fastener 10 connected, the two fasteners 9 . 10 on a lid 11 are attached. The first fastener 9 extends through a first opening 38 a mounting element 37 , which can also be called a mounting plate. The second fastener 10 extends through a second opening 39 of the mounting element 37 , The mounting element 37 is between the connecting element 8th and the lid 11 arranged.

The two fasteners 9 . 10 are identical to each other in the present case. That is why it becomes representative in 2 first fastener shown on the left 9 described.

The first fastener 9 has a head portion 13 , a guide section 14 and an attachment portion 15 on that along a longitudinal axis L of the first fastener 9 are arranged one behind the other. The leadership section 14 is between the head section 13 and the mounting section 15 arranged. The leadership section 14 has a circular cross section and has a smaller diameter than the head section, which is likewise circular in cross section 13 , Due to the smaller diameter of the guide section 14 opposite the head section 13 an undercut is formed.

The fastening section 15 has a thread that goes into the material of the lid 11 is screwed in. The fastening section 15 extends through the first opening 38 of the mounting element 37 ,

For mounting the lid fitting 1 will be the assembly element first 37 from a pre-assembled state in which the first fastener 9 in the first opening 38 and the second fastener 10 in the second opening 39 sits with the lid 11 connected. This will be the first fastener 9 and the second fastener 10 in the lid 11 screwed. By sitting the fasteners 9 . 10 in the respective opening 38 . 39 of the mounting element 37 is screwed in so that the fasteners are positioned exactly 9 . 10 to each other is realized. In addition, the fasteners will tilt 9 . 10 prevented during screwing. The respective management section 14 the fasteners 9 . 10 lies on the mounting element after screwing in 37 so that the bolt biasing force is large from the guide portion 14 about the mounting element 37 on the lid 11 is transmitted. This will sink the fasteners 9 . 10 in the lid 11 prevented when the screw torque is incorrectly selected.

In the 7 to 9 , which are described below together, is a second embodiment of the assembly unit 36 ' shown, which is different from the assembly unit described above 36 differs in that the mounting element 37 a first insert element 40 and a second insert element 41 includes. The first and the second insert element 40 . 41 are each designed as an expansion element, but are not limited to this. Regarding the similarities of the first configuration of the assembly unit 36 and the second embodiment of the assembly unit 36 ' at this point, reference is made to the preceding explanations, the same or similar elements being provided with the same reference symbols.

The mounting element 37 ' the assembly unit 36 ' has a first receiving opening 34 in which the first insert element 40 is inserted, and a second receiving opening 35 in which the second insert element 41 is used on. The insert elements 40 . 41 are present in the respective receiving opening 34 . 35 clipped. However, it is also conceivable that the insert elements are injection molded onto the mounting element. The first element 40 includes the first opening 38 the assembly unit 36 ' and the second insert element 41 includes the second opening 39 the assembly unit 36 ' , In the opening 38 . 39 the fasteners are seated as previously described 9 . 10 on.

In the 10 to 12 , which are described below together, is a third embodiment of the assembly unit 36 " shown, which differ from the first embodiment of the assembly unit 36 by the embodiment of the fasteners 9 ' . 10 ' different. Regarding the similarities of the first configuration of the assembly unit 36 and the third embodiment of the assembly unit 36 " reference is therefore made to the preceding explanations, the same or similar elements being designated with the same reference symbols.

The first fastener 9 ' and the second fastener 10 ' are identical in the present case, so that the example in 10 first fastener shown on the left 9 ' is described. The first fastener 9 ' comprises a ring element 3 , The ring element 3 has the head section 13 and the guide section 14 on. The ring element 3 is designed in a ring shape and includes a central opening in which a threaded element 4 that the threaded section 15 has, sits.

After the intermediate assembly step in which the assembly unit 36 with the lid 11 has been connected is used for further assembly of the cover fitting 1 the connecting element 8th with the first fastener 9 and the second fastener 10 connected. The connecting element 8th is designed in sheet form and has a first guide slot 16 and another second guide slot 17 on. The first guide slot 16 is in an assembly direction M open towards the front. The second guide slot 17 is in the sheet material of the connecting element 8th brought in closed. The second guide slot 17 has an extended section in the mounting direction M at the front 18 on.

In the direction of assembly M viewed, the two guide slots 16 . 17 a width based on the diameter of the guide sections 14 of the two fasteners 9 . 10 is adjusted or is slightly wider. In addition, the guide slots 16 . 17 , in the direction of assembly M considered, narrower than the head sections 13 the fasteners 9 . 10 ,

For easy assembly of the connecting element 8th to the fasteners 9 . 10 to ensure, as already mentioned, is the first guide slot 16 in the direction of assembly M open at the front. In addition, the second guide slot 17 an expanded section 18 whose diameter is larger than the diameter of the head section 13 of the second fastener 10 , Thus, the connecting element 8th on the fasteners 9 . 10 put on, the second fastener 10 through the expanded section 18 in the second guide slot 17 intervenes. By moving the connecting element 8th in the direction of assembly M engages behind the connecting element 8th the head sections 13 of the two connecting elements 9 . 10 , the connecting element 8th between the head sections 13 of the two connecting elements 9 . 10 and the mounting element 37 is positioned.

For fixing the connecting element 8th on the two fasteners 9 . 10 is a fixing device with a fixing element in the form of a tab 19 intended. The tab 19 is by means of an eccentric element 20 on the connecting element 8th attached. The tab points to this 19 a mounting recess 21 on in which the eccentric element 20 with an eccentric approach 22 sitting. The mounting recess 21 is circular in cross-section, as is the eccentric approach 22 , the eccentric element 20 about an axis of rotation D in the mounting recess 21 is rotatable.

In the connector 8th is a hole 23 provided in which an eccentric approach 22 of the eccentric element 20 engages and rotates on the connecting element 8th is riveted. The eccentric element 20 can be one of the eccentric approach 22 defined eccentric axis e opposite the connecting element 8th rotate. The eccentric axis e is parallel with distance to the axis of rotation D arranged.

For turning the eccentric element 20 this has a cross recess 24 so that the eccentric element 20 can be turned with a screwdriver. Due to the eccentric arrangement of the eccentric approach 22 to the mounting recess 21 there is an eccentric wobble of the mounting recess 21 around the eccentric axis e instead, causing the tab 19 relative to the connecting element 8th is moved.

On one of the mounting recess 21 distant front end 27 the tab 19 points the tab 19 a fixing recess 25 on that the head section 13 and the guide section 14 of the first fastening element serving as a securing element 9 receives. The fixing recess 25 is also circular in cross-section and ensures a secure hold of the tab 19 on the first fastener 9 , This is a relative displacement of the connecting element 8th opposite the two fasteners 9 . 10 prevented and the elements mentioned are fixed to each other.

The connecting element 8th points parallel to the mounting direction M running guide walls 28 . 29 on between which the tab 19 is included. When turning the eccentric element 20 becomes the front end 27 the tab 19 therefore in the direction of assembly M emotional. This allows the position of the connecting element 8th relative to the first fastener 9 and thus relative to the lid 11 set linearly in and against the mounting direction.

In the swivel arm 7 is a compression spring, not recognizable here, arranged on the one hand against an abutment 30 near the first body axis K1 and on the other hand against a pressure element 31 is supported. The pressure element 31 is thus towards the connecting element 8th acted upon by force, the pressure element 31 a role 32 with which the pressure element 31 against a positioning contour 33 of the connecting element 8th is supported.

The positioning contour 33 points in the circumferential direction around the first cover axis D1 a changing distance to the first lid axis D1 on. Here is the contour 33 designed such that the pressure element 31 over the largest swivel path of the lid 11 or the connecting element 8th a torque is generated that covers the lid 11 energized towards the open position. In an area between an intermediate position, which is between the open position and the closed position of the cover 11 and the closed position is the positioning contour 33 designed such that the lid 11 force is applied in the direction of the closed position.

In principle, however, it is also conceivable that a cover fitting without the application of force is used or a cover fitting is used in which the cover 11 via another hinge with the furniture body 6 connected is. A cover fitting can also be provided, which serves to hold a folding cover, the folding cover being formed from at least two elements which are arranged vertically one above the other in the closed position and which are pivotally connected to one another.

Through the assembly unit 36 can be aligned from one side of the swing arm 7 and connecting element 8th that together the assembly direction M define, and on the other hand, the first and the second fastener 9 . 10 be ensured. Thus, the entry of an undesirable torque resulting from a tensioned state during assembly onto a bearing between the connecting element 8th and the swivel arm 7 about an axis perpendicular to the lid axis D1 and analogously to a storage between the swivel arm 7 and the base element 2 about an axis perpendicular to the body axis K1 be prevented.
