721 73 "I Hinge with locking member

The invention relates to a hinge provided with a closure member, comprising a first hinge part and a second hinge part articulated to each other by a pivotable shaft, and a closure member loaded with at least one spring, the closure member being provided with an opening 10 for said closure member. pressed by said at least one spring to protrude and close said hinge portion when closing said first and second hinge portions.

Hinges provided with a closure member are already known in the furniture industry to ensure that the cabinet door remains closed in the closed position. Cabinet doors with such hinges do not need to be separately fitted with another type of closure member, such as a lock or a magnetic closure, unless it is desired to make the cabinet lockable. However, such hinges are complex in structure and, as a result, expensive to manufacture. One such furniture hinge with a closing member is disclosed, for example, in DE-GM 8 030 213.2. A hinge according to said DE publication has a spring-loaded closure member arranged in the second hinge part and a recess is in turn formed in the second hinge part, into which the closure member is arranged to protrude when the hinge is in the closed position.

However, the closure member according to said DE publication has a complex structure and comprises a spring-loaded articulated lever pivotally articulated to another hinge part by a articulation shaft separate from the hinge axis. Such a closure member thus consists of several separate parts which are small in size and, as a result, the assembly of the hinge provided with such a closure member is quite time-consuming.

It is an object of the present invention to provide a hinge with a closure member which achieves the same advantages as with the prior art solutions and which is furthermore considerably simpler in construction and less expensive to manufacture than known hinges with a closure member. In order to achieve this, the invention is mainly characterized in that the closure member is arranged in the recess formed in the second hinge part so as to be movable in a substantially perpendicular direction with respect to the axis.

The advantages of the invention can be pointed out e.g. following. The structure of the closure member in the hinge is very simple. The manufacturing and assembly costs of the hinge are e.g. as a result, made very small. The closure member is fitted to the hinge so that it can be replaced, if necessary, by a simple operation without the need to disassemble the hinge. The hinge does not even need to be removed from its application during the replacement of the closure member.

The invention will now be described by way of example with reference to the figures of the accompanying drawing.

Figure 3 shows a more detailed detail of Figure 1.

Figure 4 shows the hinge closure member without springs.

Figure 5 shows the hinge closure member with the springs in place.

Figures 1 and 2 show the hinge according to the invention assembled and in the closed position. Reference numeral 1 denotes a first hinge part intended to be fixed, for example, to a wall of a cabinet or to another corresponding fixed component 30. In order to fasten the first hinge part 1 to the wall, a hole 12 is formed in the first hinge part for the screw, as well as guide pins 11 on the side facing the wall for aligning the hinge. Reference numeral 2 denotes a second hinge part intended to be attached to a door or the like. The second hinge part 2 of the Hinge-35 is not intended to be fastened to the door by screwing, but for fastening there is a groove to be machined in the door into which the second hinge part 2

The first hinge part 1 and the second hinge part 2 are connected to each other by a shaft 3, around which said hinge parts 1 and 2 can be pivoted relative to each other by more than 180 °. A closure member 4 is loaded in the second hinge part 2 and is loaded with at least one spring 5. An opening 9 is formed in the first hinge part 1 into which the closure member 4 is arranged to protrude when the hinge is in the closed position according to Fig. 1.

Figure 3 shows in more detail the arrangement of the closure member 4 in the hinge. According to Fig. 3, a recess 6 is formed in the second hinge part 2, in which the closing member 4 can move back and forth under the load of the spring 5 in a substantially perpendicular direction with respect to the shaft 3. A resilient tongue 7 is formed in the closure member 15, which prevents the closure member 4 from protruding out of the recess 6 when the hinge is open. When the hinge is opened, the tongue 7 protrudes against the abutment surface 8 in the second hinge part 2, preventing the closure member 4 from escaping from the recess 6. The tongue 7 is arranged resiliently so that after passing the abutment surface 8, the tongue 7 protrudes outwards, preventing the closure member 4 from escaping from the recess 6. The closure member 4 can be simply removed from the recess 6 by pushing the tab 7 inwards, the spring 5 pushing the closure member 4 out of the recess 6.

As already shown in connection with Fig. 1, an opening 9 is formed in the first hinge part 1, into which the closing member 4 is arranged to protrude when the hinge is in the closed position. The opening 9 has an oblique surface 10 along which the closing member 4 is adapted to slide when closing the hinge. The oblique surface 10 is arranged obliquely with respect to the direction of movement of the closure member 4 so that when the hinge is closed the closure member 4 slides along said oblique surface 10 and tightens the first hinge part 1 and the second hinge part 2 under the action of the spring 5. When the hinge 35 is opened, the first and second hinge parts 1 and 2 pivot relative to each other initially so that the oblique surface 10 forces the closure member 4 to protrude in the recess 6 and after the oblique surface 10 passes the closure member 4. As already mentioned above, the closing member 4 cannot protrude completely out of the recess 6 when the hinge is opened, because the tongue 7 protrudes against the abutment surface 8.

Figures 4 and 5 show a preferred embodiment of the closure member 4. The closure member 4 is preferably made of plastic and is provided with pin-like guides 14 on each side, which are adapted to protrude into the springs 5. Thus, according to Figures 4 and 5, the preferred embodiment 10 of the closure member 4 has two pin-like guides 14, in which case, of course, two pieces of springs 5 are also required. According to the figures, the springs 5 are preferably helical springs. It is, of course, clear that the springs 5 can be other than coil springs. Leaf springs of metal or plastic, for example, can be used as springs, and rubber springs can also be used in the solution according to the invention. The number of springs 5 may also vary, but solutions according to the most preferred embodiments use either two or one spring.

The invention has been described above by way of example with reference to the figures of the accompanying drawing. However, this is not intended to limit the invention in any way to the examples shown in the figures, but many modifications are possible within the scope of the inventive idea defined by the following claims.
