Abstract

1439911 Hinges R HEINZE 12 July 1973 [1 Aug 1972] 33272/73 Heading E2F A hinge for the door 15 of a cabinet 13 designed to urge the door to a closed position comprises a fitting 12 secured to a wall of the cabinet and a fitting 4 secured to the door by a hollow barbed cup 2 and a barbed dowel 5 both embedded within the door, the two fittings being pivotally connected by a pair of hinge arms 6, 7. The fitting 4 has a rectangular-section cavity 16 to accommodate a slidable locking element 17 which has a hollow rectangular section shank 19 extending into a hook member 18 formed with a cam face 24. A pin 21 secured in fitting 4 passes through a slot 20 in shank 19, a compression spring 22 being trapped between pin 21 and the end face of cavity 16 to urge cam face 24 into contact with a looped end 6a of arm 6 thereby exerting a force on the door tending to close it. Different profiles for cam face 24 are described and it is stated that the cam face may engage a roller instead of looped end 6a.

Description

A and the RICHARD 40547 The resent invention concerns a hinge for cabinet doors the like and comprises two pivoted levers and a element which is accommodated in insertion displaceable under the bias of a spring and the integral locking cam of which cooperates with a roller or a bearing sleeve for the Hinges pf this type produce the force necessary for keeping a door without holding devices spring latches or the acting positively or th Hinges are know i which a lockin member formed as roller and with a locking cam Integral with the With this unsuitable arrangement difficult to form the cam on the fitting or to mount it thereon on the other due to the circular of the roller only relatively weak retaining forces can be latch hinges axe also known which have a pivotably mounted triangular locking element with a bearing sleeve for the pivoted This design requires particularly for the locking element and spring a considerable amount of spac which makes a small compact It is also difficult particularly if strong closing forces are necessary to the then powerful The object of the present Invention is therefore to provide a correctly and mounted latch hinge which produces necessary closing forces even if comparatively strong whilst retaining a small compact There is provided in accordance with an embodimen of the present a latch hinge for connection of two parts of furniture for hinging a door to a cabinet and the the comprising two pivoted levers a cup insertable in one part of the for the and containing a displaceable spring actuated locking element made with a locking cam which cooperates with a roller or with the bearing sleeve of the pivoted wherein the locking element is displaceably held in guide passage outside the receiving so the member is displaceably guided in parallel or at an acute angle to the surface of the and the end of the locking along which the convex portion of the locking extends projects beyond the guide passage into the inside of the Further accordance with a embodiment of the invention there provided a latch hinge as described hereinabove wherein the locking cam has curved portion which cooperates with the roller or the bearing In another embodiment of the present invention it is that a defined position of the locking is obtained in its guidance by integral guiding fixing means or by a section di ering from the circular The advantages achieved by the present invention reside more particularly in the feature that the incorporation and compression springs of powerful is since spring diposed in the receiving bore has no of deflection and compression of the spring can be e cted by pressure on its free end in the direction of the axis of said The present arrangement of spring and looking member inclined at an acute angle to the surface of the door also makes it possible if the locking cam is suitably exploit the force of the spring and therefore to obtain an optimal closing foroe for be In order that the invention carried into praotioe an embodiment will now be described in by way of with reference to the accompanying drawings in shows a section through a fitted latch hinge in the closed shows a perspective view of a dismantled hinge in its open shows the locking element in Figs various possibilities of the locking or curve of the locking member according to and 2 show a hinge casing 1 which comprises in known manner an insertion cup 2 having a barbed profile 3 insertable in the door and an integral housing for a locking element A spreading dowel 5 mounted in the usual manner on the housing rotation and As the hinge casing 1 is connected by two pivoted levers 7 at the pivotal centres 11 to a fitting 12 which is also in known manner and therefore not to the wall of a The housing has a guide passage preferably extending at an acute angle to the surface of the door for the locking element present slightly inclined arrangement of the guide passage 16 has been because the best closing results have been achieved it is immediately poseible to allow the guide passage 16 to extend parallel to the surface 15 of the door in order to obtain a low overall height of the housing In such a it appears advisable to adapt the lockin cam or curve to the new The locking element is and engages by its hook member into the interior of the insertion cup The guide shank 19 preferably has a rectangular in order to obtain a defined position immediately the locking element 17 is introduced into the similarly square guide passage a feature which is a great help for the driving in of the looking pin 21 which has to engage through the slot 20 in the locking element Due to this large supporting surfaces are also obtained on the adjacent parte which receive any resulting forces and make them as far as wear is if the surface friction should exceed an acceptable the guide shank 19 or guide passage 16 may be provided with eliding ribs reducing the bearing due to the described form of it is poseible for the locking member 17 to be prevented from and this results in a favourable relief of the locking it may be mentioned in this that these may of course be obtained by other in the case of a Circular of the guide shank by guide grooves and integral locating projections or pine and the At the end of the guide shank the locking element 17 is provided with the slot 20 in conjunction with the locking pin 21 mounted on the is adjusted to the necessary movement of displacement resulting from the engagement between the guide cam 2k and the pivoted sleeve At the same the locking pin 21 provides a point of support for the spring 22 and secures the locking element 17 from dropping The cavity 28 in the guide shank 19 receives the compression spring On the outer surface of the hook member locking element 17 carries an integral calculated relatively to the overall area preferably a convex locking cam 2k with the bearing sleeve 6a of the pivoted lever 6 which pivots about the point The locking cam 2k may naturall also with an extra roller or The lower part of the locking cam 2k may according to the proposed use and desired locking action be provided with a special For special or desired closing or holding properties may be obtained by differently selected angles of incline of the member Furthermore the curve member may have a recess in which the pivoted sleeve 6a or it may have a cam behind which the pivot sleeve 6a or a shoulder 27 may be provided behind which the pivoted sleeve 6a becomes particularly the introduction of the compression spring also greatly simplified in the hinge of the present this assembling being effected in such manner that the locking element 17 is inserted into the opening in the guide the compression spring 22 passage 16 faolng the insertion oup 2 and is then introduoed into the opposite In the case of the closed hinge according to a suitably formed tool can now be placed on the free end of the compression spring 22 and said spring 22 compressed until the locking pin 21 can be inserted Due to the fact that the compression pin 22 is disposed in a cavity 28 open only at one the risk of the compression spring 22 springing away laterally ie eliminated and assembly is effeoted more rapidly and insufficientOCRQuality
