Definitions

  • the invention relates to a wide-angle hinge with two scissor-like intersecting articulated arms that are connected to one another by a hinge pin, one end of which is articulated to the mutually facing, inner ends of a supporting wall stop part and a door stop part, which is preferably pot-shaped, and their swinging ends Swing levers are articulated to the outer ends of these stop parts, with a cam arranged in the region of a joint, the cam surface against which a sliding or rolling element loaded by a closing spring and pivotable by a joint part about the axis of the joint is pressed that the closing spring only acts in the closing direction in the area of the closed position of the joint parts.
  • EPC can be produced without additional effort and without additional parts having to be stored and kept ready during final assembly, thereby optionally with and without a locking device that In a rocker arm between its hinge axes, a sliding or rolling element acted upon by a compression spring is optionally provided, which cooperates with a cam provided in the region of the joint of the rocker arm.
  • the known wide-angle hinge already corresponds to rational industrial production methods in that different wide-angle hinges can be produced with simplified final assembly with reduced storage, because only rocking levers without a locking device and with pre-assembled locking devices have to be kept ready.
  • the object of the invention is to further develop the known wide-angle hinge in a compact and slim embodiment in such a way that it can be manufactured without locking devices and with locking devices with different locking characteristics while maintaining as large a number of the same parts as possible without major additional assembly effort.
  • the supporting wall and door stop parts and the rocking levers connected to them can be retained unchanged regardless of the type of hinge to be produced.
  • the intersecting articulated arms also have a basically constant outer shape, so that they always match the basic parts that remain unchanged.
  • the articulated arms can be provided with corresponding cams and spring-loaded sliding or rolling bodies and also preassembled immediately, so that during final assembly only the respective ends of the articulated arms are connected to the supporting wall and door stop parts and the rocking levers Need to become.
  • the parts forming the locking device can be connected in one piece to the articulated arms, but at least arranged in a space-saving manner in them and integrated into them in such a way that slim and compact designs result.
  • the wide-angle hinge according to the invention also complies with standardization which simplifies production in the production of different hinge types.
  • the tool costs can also be reduced due to the fact that the simply designed individual parts of the wide-angle hinge largely match.
  • the cam is expediently formed directly on the articulated arm.
  • the articulated arm can consist of a U-shaped sheet metal stamped part with legs angled from a web part, the bores for the articulated bolt connecting the articulated arm with the other articulated arm being provided in its legs and the cam surface consisting of at least one tongue-shaped part bent out of the web part. In this way, the cam can only be produced together with the articulated arm by punching and bending.
  • the cam surface can also consist of a transverse web formed by at least one punched-out section of the web part, a snap effect being able to be achieved in the closing area with such a cam surface.
  • the cam can also consist of a plastic or metal part fastened by the hinge pin.
  • the sliding body is formed by the free end of a prestressed leaf spring, which is the closing spring.
  • the leaf spring can have a hairpin-shaped curved part, the resilient leg of which is supported on the cam and the other leg of which angled straight part serving for fastening is angled.
  • the arc formed between the straight part and the leg can be supported on a bolt fastened to the legs.
  • the sliding body can also consist of a sliding block which is guided between the web part and the bead-shaped beads of the legs of the articulated arm and which is acted upon by a compression spring which is clamped between the latter and a tongue bent out of the web part between the legs.
  • a rolling body consisting of a cylindrical roller can be provided, which is inserted into an end groove of the sliding block designed as a guide body.
  • the sliding body can be made from a with an abutment bracket that is attached to the articulated arm or its web part Stigt is hinged flap part, wherein a wedge-shaped body made of elastomeric material is held in the wedge-shaped space between the abutment and the folding part.
  • the cam is provided on the articulated arm articulated on the door stop part and the articulated arm articulated on the supporting wall stop part is provided with the closing spring and the sliding or rolling element.
  • the cavity in the articulated arm in question has been used in a particularly advantageous manner to arrange the locking mechanism.
  • the wide-angle hinge shown in FIGS. 1 and 2 consists of the longer articulated arm 1 crossing with the shorter articulated arm 2, both of which are articulated to one another by the articulated pin 3 to form a universal joint.
  • the longer articulated arm 1 is articulated around the articulation pin 4 in the cup-shaped articulated part 5, which forms the door stop part and is embedded in a blind hole milled into the door 6.
  • the longer articulated arm 1 is articulated by the articulation pin 7 with the rocker arm 8, the other end of which is articulated by the articulation pin 9 with the supporting wall stop part 10.
  • the shorter articulated arm 2 is connected at its inner end in an articulated manner to the door stop part 10 by the articulated bolt 11.
  • the outer end of the shorter articulated arm 2 is articulated by the articulation pin 12 to the rocker arm 13, the other of which is articulated by the articulation pin 14 to the cup-shaped hinge part 5.
  • the rocker arm 13, like the rocker arm 8, consists of a stamped, U-shaped sheet-metal part, with indentations being provided in the outer edge of the legs of the rocker arm 13, in which there are limiting the opening angle in the open position of the longer articulated arm 1 bearing bearing pin 4 supports.
  • the supporting wall stop part 10 consists in the usual manner of a fastening plate screwed to the supporting wall, on which the hinge arm provided with the articulation pin 11 is fixed by screws.
  • the hinge arm 1 consists of a stamped sheet metal part, from the web part 15 of which the side legs 16 are bent at right angles.
  • Two tongues 17, 18 are punched out of the web part 15 by punching, of which the tongue 18 is curved approximately concentrically sector-shaped around the bearing pin 3 in the manner shown and the tongue 17 is angled inwards.
  • the tongues 17, 18 are connected to the legs 16 by a transverse web of the web part 15 present between them.
  • the shorter articulated arm 2 also consists of a U-shaped sheet metal stamped part.
  • a leaf spring 21 is fixed in the articulated arm 2 by a bolt 20 which is connected to the web portion 19 of the latter and has the legs thereof.
  • This leaf spring has a hairpin-shaped curved part, the resilient leg 22 of which slides on the cam surface formed by the inwardly bent tongues 17, 18.
  • a straight part 23 is bent from the other leg of the hairpin-shaped part and is held on the web part (19) of the articulated arm 2 in that the leaf spring with its bent part lies between the straight part 23 and the hairpin-shaped part on the bolt 20 supports. Since the leg 22 is prestressed on the cam, the leaf spring (21) is pressed against the retaining pin 20.
  • the resilient leg 22 of the leaf spring 21 essentially slides over the opening region of the wide-angle hinge on the part of the cam curve formed by the web part and the bent tongue 18 which is concentric with the hinge pin 3. In the closing area, the resilient leg slides over the web part in the direction of the angled tongue 17, so that a sufficiently large closing force is generated.
  • the cam consists of a plastic part 24 which is fastened by the articulation pin 3.
  • the plastic part 24 is provided with an extension 25 which has a groove into which the tongue 26 angled from the web part engages.
  • the leaf spring 21 is formed in the manner shown two layers.
  • a sliding body 27 is guided so as to be longitudinally displaceable in a guide, which is formed by its web part (19) and by bead-like beads 28 which are stamped into the lateral legs of the articulated arm 2.
  • the compression spring 30 forming the closing spring is clamped between the sliding body 27 and a tongue 29 which is angled inward from the web part 19.
  • the end face of the sliding body 27 is provided with intersecting grooves, of which the roller-shaped rolling body 31 is inserted. This rolling element is pressed via the sliding element 27 by the compression spring 30 against the cam surface, which is formed by the web part 15 and the tongues 17, 18 bent therefrom.
  • the cam formed in the web part 15 of the longer articulated arm 1 is essentially formed only by the remaining cross web 32 of the web part 15.
  • the interacting with the web-like cam 32 sliding body consists of a flap-shaped part 33 which is integrally connected by a film joint 34 to the abutment block 35 made of plastic.
  • the abutment block 35 is connected by a bolt 36 to the legs of the shorter articulated arm 2 and held in contact with the web part 19 thereof.
  • a wedge-shaped block 37 made of elastomeric material is inserted into the wedge-shaped between the flat end face of the plastic block 35 and the tongue-shaped flap part 33.
  • the wedge-shaped block 37 has a foot 38 which engages in a recess 39 in the plastic block 35. Since the flap-shaped sliding part 33 slides over the rear edge of the web-shaped cam part 32 during closing, a pronounced snap action is achieved when closing with the embodiment according to FIG. 5.
