Sweden-Sweden (SE), (7M Ruska & Co (5 ^) Hinge with hidden hinge shaft -

The present invention relates to a hinge with a hidden hinge shaft, comprising a first hinge part made for mounting in at least a partially recessed position for one of the two articulated joints with each other by a hinge member and a second hinge part made at an angle. and having a first leg adapted to be joined to the second of said two members and a second leg extendable into the cavity in the first hinge portion and adapted at its outer end to be articulated therewith to allow mutual pivotability between the two hinge portions about the hinge axis located in a part for recessed mounting of the first hinge part, wherein the member resiliently movably fitted to the first hinge part is adapted to co-operate with the selected part of the second hinge part, acting as it approaches a certain pivot position in the first with respect to one hinge portion in the direction of the second hinge portion against said position.

m

A hinge of the above-mentioned type is previously known, in which the resiliently movable member is formed by an elastic flexible tongue 2 6381 5 which is integral with the first hinge part, which is made entirely by molding of plastic. Such a resiliently moving member has a practical risk, since the force exerted by said member on the second hinge part weakens over time and, in the worst case, may cease completely.

The object of the present invention is to provide an improved hinge of the type mentioned in the introduction, in which said risk is completely eliminated or at least considerably reduced. The hinge according to the invention is mainly characterized in that the resiliently movable member is formed by a spring-loaded discrete element movably mounted on the first hinge part, for example in the form of a piece of nylon or other suitable plastic material, and that the selected part a cam surface on the side remote from the hinge axis of said leg, said cam surface extending substantially in a direction forming an acute angle with the longitudinal direction of the second leg.

A hinge according to, for example, a selected embodiment of the invention will be explained in more detail below with reference to the accompanying drawing, in which Figure 1 shows a perspective hinge in a cabinet door and cabinet wall mounted, with the cabinet door required open, Fig. 2 shows a section of the hinge in Fig. 1 , Fig. 3 shows a section similar to Fig. 2, in which case, however, the cabinet door is required to be closed, and Fig. 4 shows a hinge part mounted on the door, showing this as seen from the rear.

The hinge shown in the drawing is formed by two hinge parts articulated to each other, preferably of metal, namely a first part, generally indicated by reference numeral 10, and a second part, generally indicated by reference numeral 11. Part 10 is shown in Figures 1-3 mounted on the cabinet door 12, while part 11 is shown mounted on the cabinet wall 13 · 6381 5

The hinge part 10 is formed by a planar front plate 14 and two parts 15 and 16 projecting from its rear side, which when inserted into the door 11 are inserted into a cylindrical cavity 17 drilled therein, the part 10 being fixed to the door through screws 18 passing through the front plate 14.

The hinge part 11 is made as a strip profile with short, longitudinal edge flanges, bent at an angle, and has two branches 19 and 20, the straight main parts of which form an angle of about 90 ° with each other. However, said angle, as shown in the drawing, may be less than 90 °. The longer leg 19 is intended to be inserted into the longitudinal chute 22 in the fitting 22 mounted on the inside of the cabinet wall 13 by means of screws 21, in which the leg 19 can be locked in an adjustable position by a screw 23 fitted in an elongate hole in the fitting. The shorter leg 20 is formed at its outer end as a bearing sleeve for a 2 M hinge pin 25, the end portions of which are fitted in aligned holes in the two opposite walls of the part 16 of the part 10. This part 16 has a generally frame-like shape and delimits a cavity into which the hinge part 11 can be partially fitted.

Reference numeral 27 preferably denotes a Z-shaped element of nylon or other suitable plastic material movably mounted on the hinge part 10 and acted in the direction of the spring 28 against the position where the end portion of the resilient member protrudes into the cavity 26 of the limited dimension. in its longer branch 19 provided with a depression 29 which forms a cam surface for cooperating with the element 27, extending in a direction forming an acute angle with the shorter branch 20. The spring biased element 27 and the cam surface formed by the depression 29 co-operate with each other, acting on the door 11 in the direction of its closing position as it approaches its closed position and then when the door has reached its closed position, releasably securing it to this position without recourse to magnetic locks or other special holding member to ensure such locking of the door.

Claims (2)

A hinge having a hidden hinge shaft, comprising a first hinge part (10) made for mounting in an at least partially recessed position in one (12) of two articulated joints with each other by means of a hinge member (12, 13), and a second hinge part (11) bent at an angle and having a first leg (19) adapted to be connected to the second (13) of said two members (12, 13) and a second leg (20) extensible in the first hinge portion (10). ) and adapted at its outer end (24) to be articulated therewith to allow mutual pivoting between the two hinge portions (10, 11) about a hinge axis (25) located in the portion of the first hinge portion (10) for flush mounting, wherein a member (27) resiliently movably fitted to the first hinge part (10) is adapted to co-operate with a selected part (29) of the second hinge part (11) approaching a certain pivoting position with respect to the first hinge part (10) in the direction of the second hinge part (11) against said position, characterized in that the resiliently movable member is formed by a spring-loaded separate element movably mounted on the first hinge part (10) ( 27), for example in the form of a body (27) of nylon or other suitable plastic material, and that the selected part of the second hinge part (11) is formed by the cam surface (29) of the first leg (19) near the bent transition point between the two arms (19, 20) on the side remote from the shaft (25), said cam surface (29) extending substantially in a direction forming an acute angle with the longitudinal direction of the second leg (20). Hinge according to claim 1, characterized in that said cam surface (29) is formed in a substantially straight main part of the second hinge part (11) obliquely inwards to an obliquely inwardly directed part of this branch (19) which on the rear side of the second hinge part (11) a pocket into which the edge portion of the first hinge part (10) can be fitted.
