7 Claims, 5 Drawing Figures COMBINED DOOR STOPPER AND HINGE ASSEMBLY BACKGROUND OF THE INVENTION The present invention relates generally to door mounting structures and more particularly to a combined assembly operating both as a door hinge and stopper. More particularly the present invention relates to a construction wherein a combined hinge and stopper may be formed with a pair of hinge leaves having a torsion bar spring operativcly interposed therebetween. The spring is formed as a generally rodlike member which is bent to have its ends configured as a pair of spring arms. The torsion spring is fixedly mounted upon one of the hinge leaves and a roller which operates as a cam follower is mounted upon one of its spring ends. The other hinge leaf includes a stop member generally formed with a cam surface which is engagcable by the roller to perform the stopping function of the assembly. The torsion bar spring is so mounted and arranged in a front slotted recess of one of the hinge leaves that the two leaves may be turned freely relative to each other about a hinge pin through a certain opening angle before the roller engages the lirst of the stop cam surfaces. The force of the torsion bar spring resists further relative rotation of the hinge leaves in both directions thereby requiring additional force to be applied lifting the roller from engagement with a portion of the cam stop surface against the load of the torsion bar spring when the hinges are to be ro tatcd further.
Door stoppers of the aforementioned type structurely combined with a hinge member have been heretofore known as, for ctamplc, disclosed in German Pat. Nos. l,584,t)39 and 2,041,017. In such known assemblies, a torsion bar spring is held in a block of one of the hinge leaves extending transversely to the hinge axle within bores or similar recesses. However, in such known assemblies the construction thereof is limited in application to hinges comprising at least one hinge leaf formed as a drawn metal part and having a U-shaped crosssectional profile. For many applications the use of a hinge leaf designed as a drawn metal part introduces an undesirable increase in the cost of the hinge. Furthermore, the stop member associated with the stop arm of the torsion spring mounted on one of the hinge leaves in the type of door stopper above described is formed by a corresponding block of the hinge leaf extending transversely to the hinge axle. In practice, this requires that the hinge leaf be designed as a drawn metal plate. Apart from the fact that hinge leaves designed as pressed metal parts are not always desirable for the reasons mentioned above, they have the additional disadvantage that the stops consist of drawn metallic material which is relatively easily deformable and which is subject to considerable wear when in use. Thus, tolerance increases gradually appear in the hinge thereby leading in operation to the occurrence of a relatively loud cracking noise in the door stopper.
In view of the state of the art herein before discussed, the present invention is directed to the problem of pro viding a door stopper of the above mentioned type which is structurally combined with a hinge member and which permits, on the one hand, the use of conventional hinge profiles for the production of the hinge leaves and, on the other hand, provision of hard bear ing surfaces in the range of the stop members formed on the other hinge leaf cooperating with the stop arm of the torsion spring irregardless of the material which is used for the production of the hinge leaf. The invention is further aimed at a design of the stop arm of the torsion spring and of the stops on the hinge leaf member cooperating therewith which will eliminate the cracking noises which occur even after prolonged use of the hinge, thereby giving rise to more desirable operating features of the assembly.
SUMMARY OF THE INVENTION In accordance with the present invention, both of the hinge leaves of the assembly are formed in a known manner from molded pieces. with the hinge leaf having the torsion bar spring mounted thereon being cut to length from elongated stock having a desired rolled hinge section and being provided with a groove extending parallel to the hinge axis to receive the torsion spring therein. The shaft of the torsion bar spring may be locked within the groove by means of forged protubcranccs which extend from at least one of the edges of the groove in a direction transversely of the groove axis,
Since one of the hinge leaves may be cut from elongated rolled stock having the cross sectional configuration of the hinge leaf. the groove which receives the torsion bar spring may be arranged in the stop side of the hinge section with one of its sides arranged at an angle of about 43 relative to the surface of the leaf with the other wall of the groove extending substantially perpendicularly to the stop face of the hinge leaf, The locking of the shaft of the torsion bar spring in the groove is effected in accordance with a special feature of the invention by stamped protuberances provided in the hinge leaf wall adjoining the groove and inclined toward the stop face of the hinge leaf in such a way that a nose-type projection partly overlapping the shaft of the torsion bar spring is formed. These projections overlapping the torsion spring are produced in accordance with the present invention in the range of two opposite edge zones of the hinge leaf so that, in this manner, the hinge leaf is reshaped while in the cold condition. This approach to mounting of the torsion bar spring in the hinge leaf which is produced by being cut from rolled elongated stock, gives rise to a further advant'age, in addition to permitting use of binge sections formed from rolled stock. inasmuch as the fasten ing ofthe torsion bar spring may be effected in a simple manner with minimum cost and without requiring additional parts. Since the torsion bar spring is inserted into the stop face of the hinge leaf, the fastening points are required merely to prevent the torsion bar spring from moving in a longitudinal direction with this effect being positively achieved even without great care being exerted with regard to manufacturing tolerances.
By a further feature of the present invention one of the hinge leaves is designed with a single eye or bearing hole through which the hinge can extend and the torsion bar spring is mounted or associated with this single-eye hinge leaf while the other hinge leaf is designed as a doublc-eye member made of cast iron, particularly a malleable cast iron member. In order to provide stops exhibiting sufficient wear resistance for the stop arm of the torsion bar spring, the assembly of the invention is arranged, in accordance with an additional feature thereof, so that the stops are configured in the form of a cam disk made from steel plate and attached on a block of the hinge leaf extending transversely to the hinge axis. The cam disk is preferably connected to the hinge leaf block by riveting and comprises at least one, but preferably several, cam nodules defining cam rccesses therebetween.
In accordance with an additional feature of the invention, the roller which is arranged on the stop arm of the torsion bar spring and which cooperates with the cam disk arranged on the other hinge leaf is provided with a collar which engages the underside of the cam disk. The roller collar engaging the underside of the cam disk prevents the roller from moving in an axial direction along the arm of the torsion bar spring during operation of the door stopper, thus preventing disengagement of the cam disk therefrom.
According to another feature of the invention, the roller which is arranged on the stop arm of the torsion bar spring comprises circumferential gear-like teeth and is adapted to the shape of the cam surfaces on the cam disk such that both of these elements cooperate in a formfitting manner and they are thereby substantially free of slippage or play when in an engagement. In order to prevent the teeth of the roller from skipping the cam nodules of the cam disk and to avoid the resulting cracking noises which could occur during the operation of the door stopper, the roller may be formed with larger intervals between the teeth thereof and particularly in a star-like configuration in order to dimension the size and the intervals of the cam nodules on the cam disk such that the roller is constantly in engagement therewith thereby to avoid skipping of cam nodules which are not properly arranged opposite the tooth troughs of the roller.
Finally, by an additional feature of the invention, there is provided a stop member which limits the maximum opening which can be achieved between the two hinge leaves with the stop member being formed by an inwardly directed bent portion of the outer hinge leaf designed with a double-eye configuration, which stop member cooperates by abutment with the other hinge leaf. Compared with other known structures for door stoppers of this type, this configuration has the advan tage that the door stopper operates in a manner which eliminates the necessity of utilizing the torsion bar spring stop arm as a limit stop, thereby avoiding this additional load from being placed upon the torsion bar spring and at the same time achieving a more stable limit stop effect.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its use, reference should be had to the accompanying drawings and descriptive matter in which there are illustrated and described preferred embodiments of the invention.
