Description

DETAILED DESCRIPTION OF THE INVENTION Consisting of two adjustable fitting parts, one of which can be inserted into the notch of the other with a protrusion that can be grasped at the rear, one over the other until the fitting parts and the seven-year old fitting part collide. Particularly advantageously, the metal parts abutting each other at right angles are provided with pivoting wedges which grip the projections behind them in a hook-like manner in order to interlock them with each other. This invention relates to a connecting fitting for removably connecting two plate-shaped furniture parts.

For the purpose of connecting metal parts, a connecting metal fitting having a pivoting wedge that is rotatably supported by being twisted with a screwdriver or the like is disclosed, for example, in West German Patent Publication No. 29θ9 O S B, No. 290 G'l7. ! ;No., 1st Sg/Left. 1+
No. 2g36673 and 27'lg. Known from No. 272. Known fittings are difficult to assemble and in any case require a screwdriver or other tool to assemble the fitting parts together and in some cases tightening them together. It has the disadvantage of being necessary.

In the coupling known from German Patent Publication No. 2,206 Ogq, a spring-loaded spring or pivoting wedge engages under tension behind the wide head of a counter-fitting part consisting of a pin. The wedge or pivot wedge is then supported on a stop formed by a step in the casing in the position pushed back from the insertion opening before the insertion of the pin, and a web part located in the insertion opening is provided so that the odor can be removed. , the head of the pin impinges upon insertion against the web portion, thereby displacing the wedge or pivoting wedge from the stop to release the arrest. This known connection has the disadvantage that it has a complex construction and cannot be easily removed again during the possibly necessary disassembly of the furniture.

It is therefore an object of the present invention to provide connecting fittings of the type mentioned at the outset, in which the fitting parts are used to easily assemble the furniture parts connected to them and to remove them again in a simple manner when the furniture is disassembled. It's about creating something that will flow.

According to the invention, this object is achieved in the following way: the pivot wedge is rotatably mounted in the pivot casing and is responsive to the closed position by a pivot spring. and an operating device for rotating the wedge in the uncoupling rotation direction, and an elastic device for retaining the pivoting wedge in its uncoupling position, which can be removed by an insertable protrusion on the other metal part. This problem can be solved by providing an elastic device like this.

The coupling according to the invention can be assembled in a simple manner and without tools in the following way: the swivel cage held in the uncoupling position is released after the fitting parts have been assembled, so that the spring can be rotated. The movable wedge is snapped into its closed position, and the metal parts are tensioned together due to the wedging action.

The operating device for uncoupling the pivot wedge consists of a lever fixed at right angles to the bolt and located on the upper side of the cover plate of the pivot wedge casing to serve the purpose of securing. In another embodiment of the invention, a disc with an actuating lever is rotatably mounted in the cover plate of the pivoting wedge casing concentrically with respect to the bolt axis; A notch in the shape of a shape is provided, and this notch is adapted to cover a lever fixed to the cart. When the pivot wedge then snaps from its uncoupled position into its closed position, the angle of the sector corresponds approximately to the angle over which the short lever fixed to the bolt strokes. When the actuating lever connected to the disc is pivoted into the open position, one side of the sector-shaped recess brings the lever fixed to the bolt into the uncoupled position. If this time the pivoting wedge is held in its uncoupled position by the arresting device, the disc is pivoted together with the actuating lever into its position, which corresponds to the closed position, but the pivoting wedge does not continue. When the device that gathers and restrains the metal parts together is removed, the pivot wedge can snap into its locked position without obstruction. For this reason, another version of the invention is provided with a device for retaining the pivot wedge in its uncoupled position, which device is removable by means of a telescoping projection on the other fitting part. To make this more convenient, this arresting device consists of a plate 9 provided with a hook-shaped section, which is fixed at one end to the pivot wedge and has a casing section projecting from the hook-shaped section. The iR snaps into place behind the uncoupled position.

The hook-shaped part is provided with an outwardly facing flag part, which is located within the insertion opening of the protrusion of the other fitting part, so that it releases the restraint when the other fitting part is fitted. .

According to another embodiment of the invention, the disc with the actuating gear is provided with a beveled edge and a suitably complementary undercut groove of the cover plate of the pivot wedge canong. The actuating lever, which is pivotably mounted inside and is connected to a disc, is mounted on the cover of the pivot wedge casing.
It is inserted into a sector-shaped notch in the plate, and the operating lever has a notch on one end surface, into which a cam that protrudes at the position of the rotating wedge when the connection is removed is fitted. The cam is provided at the peripheral edge of the sector-shaped notch. An operating lever with a cam is fastened in order to remove the metal parts of the coupling fitting, so that the metal parts can be easily pulled apart. In order to connect the fitting parts to each other, however, the rotating wedges are swung into their uncoupled position in the following way, i.e. the pivoting wedges are rotated by means of a restraining device located in the insertion path of the other fitting part. It is pivoted to be held in its uncoupled position, so that the pivoting wedge snaps into its locking position after engagement of the other fitting parts. The operating lever Vi connected to the disk is pivoted back from the front, so that this lever cannot be stopped in its locking position by snapping the pivot.

The hardware parts to be connected to each other should not be pulled under tension against the furniture part that supports the connected furniture parts only by their end edges; It should also be fixed such that it is not perpendicular to that plane or is slidable within the plane of the supporting urine odor part. Mobility with normal movement is prevented by means of the body, i.e. the parts of the furniture to be connected to each other are provided with interdigitated projections or pins, which are inserted into appropriate cutouts in other parts. It fits inside. This special support device, which must be provided alongside the tensioning pivoting connection, however, makes the connection additionally expensive and requires rigidity.

In order to create a connecting fitting that connects furniture parts to each other in a particularly simple and straightforward manner and without additional bin connections, according to a further development of the invention, a rear grippable projection is therefore provided. The metal part has a wide head.
and the pivoting wedge is formed by a disc-shaped, tooth-shaped element arranged in parallel planes at a distance from each other, which, behind the head, align the axis of the bolt. It surrounds the head in a fork shape and is tightly supported on the back side of the head. The connecting fitting according to the present invention is
Not only are the furniture parts to be connected to each other pulled together under tension, but the pivot wedge surrounds the shaft with the head of the hardware part in a fork-like manner, i.e. the furniture parts connected are supported. The rotating wedge is fixed so that it cannot move even at right angles to the surface of the disc-shaped element of the rotating wedge in the furniture part. The fitting part consisting of a bolt with a widened head can be fastened and hung in a particularly simple manner, for example by simply screwing in, if the bolt is threaded.

It is common practice to form the bolt section with a VC between the head and the shaft into a conical or spherical shape, and as a result, the head is! Due to the #-shaped and almost circularly curved pivot, it can be grasped from behind with just a slight end rod to tighten it.

In another form not inventive, the disc-shaped element between the pivots has circularly curved edges, which are shaped like pots that house these edges to support the pivot. It is guided in the annular groove of the Kuhn and is provided in a manner similar to -C.Since the pivot consists of d disc-shaped elements arranged at a certain distance from each other, this is due to the turning force. A certain amount of light is a component that exhibits resistance.

In order to make it more realistic, the space between the rotations is made of a punching member.
The web connecting the disc-shaped elements is located inside the peripheral circle i6.
'', and as a result the web supports the pivoting wedge edge in the annular groove groove IV.
You can open without stopping.

In another embodiment of the present invention, the 1d1 moving spring is provided as a screw spring with a 7-metal ring, the axis of which coincides with the axis of rotation between the turns and rotates. The leg of the moving spring is placed in the gauging notch, and the other leg is fixed during rotation.

According to a particularly advantageous embodiment, one end of the leaf spring is fixed in the cage, the free hook-shaped bend of which is parallel to the pivot point. The 11!1 movable wedge is provided with a shaft or protrusion, and these are placed in the preparatory position of the desire, and in that position, the pivot is pulled back from the insertion opening. 181 at the bend, and the central region of the leaf spring is located wide at the insertion ["-mouth] of the head of the other fitting part, i.e. it is at the point where it becomes unrestricted during insertion. It's getting wider.

<1 part can be assembled in a simple manner as follows: 5 times! i! The furniture part to which the fitting part with the IJ wedge is fixed forms a 11-sided gold paper part and is assembled in such a way that it can be stopped on the bolt provided with the head. The head releases the restraint between rotations, and as a result it automatically stays in its locked position. In the upper wall of the gauging between the turns an axial pin can be supported, which pin is located in the Cuzo/Glu l-11111-hi position.
The pin should be provided with an opposing stopper between the rotations at the bottom +1 (11 ends) and a stopper that moves once as follows, i.e., the rotation between the rotations should be open. It is swiveled into its position by means of a lever and works together in the following manner.

If you hold it in this position, the lock on the arm part can be unlocked. The plate spring shim 1 41 with the bent part after it came off is removed from its quasi-1 piece 1 line 1 +C, and as a result, the operating lever is turned to the position corresponding to the brocade stopper, and it hangs. When the restraining tool is released from the quasi-1] iii position by removing the l + 1 y of detention, it rotates (the key is from the quasi-II eyebrow position [starting from d to the above position) and the chiso. It is something that stays.

Instead of the pivot being also supported in the annular groove in the inner wall of the gauging, the pivot passes through the Ill' I-E spring. In order to provide a large 41 force to the pivoting force, a rotating shaft supporting a circularly curved edge on the cylindrical inner wall of the gauging is used.

According to another embodiment of the invention, the pivot spring has a substantially solid cylindrical shape and has a hole formed entirely within the head of the piece of furniture to be fixed. A bolt with a head inserted into the shell is adapted to rest in the insertion opening through a hole in the web between the hole and the edge of the furniture part. There is. This embodiment is for relatively strong furniture parts! It is suitable for samurai.

According to the carving according to non-invention 1i11Qij
The joint is formed by a circular disc around a bolt parallel to the center line of the pivot spring with a cylindrical side wall increasing laterally in its height. and during rotation, the head is provided with 711. It is provided so as to be stored in the insertion opening parallel to/below the bolt for the bolt. In this embodiment, for example, the bottom rule 1 is attached to the lower end side from the furniture wall that stands upright.
- It is difficult to connect.

In order to fix the disk provided with the rotation space to the desired position in the standing position, the disk is equipped with a sector-shaped head without walls. A4 (~In a vine, the end of the plate spring bent toward the hook facing outward in the direction of the half-frame is B, L, b, and 1). The inner wall of the casing that surrounds the disc is provided with a 1-da-raku on the 11-11 side of the sennin opening, and a lever is attached at the rear of the 7-nok opening. is n14! ! The hook fits around the neck and hangs, and the hook has a flag-like part that projects laterally into the opening. On this flag-shaped part, a decoy that is fitted into the insertion opening on the outside as in 1/CM'A'lJ--a head formed in a spherical shape on the outside of this part slides down, As a result, the pivoting wedge snaps into its locking position.
