Abstract
ABSTRACT OF THE DISCLOSURE
A method of fabricating a hinge as described, which includes the step of making a blank for a leaf: bending a marginal edge portion of the blank so that the bend has an arcuate cross section with the radius of curvature correspond-ing to the radius of a rod to which it is to be secured. The circular rod is then secured by welding on an inner side of the bend and extending axially along the bend. The securing comprises welding on an edge of the bend marginal edge portion on the periphery of the rod to secure the rod to the bend. The blank is then bent to enclose the rod circumferentially until a free edge of the bend contacts a major surface of the leaf blank to conform the bend in cross section to the cross section configuration of the rod as a cylindrical knuckle.

Description
~045800 The present invention relates to a hinge applicable -to doors of building construction, furniture such as cabinets, etc. and other articles, and relates to a method for making the same.
As to a conventional method for fabricating a hinge, such a process has been known in which each one side edge of hinge leaves is rolled up beforehand in a circular shape to form a cylindrical knuckle part, and a rod member applicable to either a hinge pintle or a thrust bearing for supporting the hinge pintle at one end thereof is tightly inserted into an aperture o~ the cylindrical knuckle part so as to be rigidly secured therewithin. In the foregoing conventional method, the following steps of process have hitherto been known that 15 the rod member is rigidly secured within -the cylindrical ~
knuckle part by piercing a check pin through apertures - --formed on both the cylindrical knuckle part and the rod member. However, according to the aforementioned con-ventional method, it is very difficult to carry out the processes for inserting the rod member tightly into the ` aperture o~ the cylindrical knuckle part; for forming an aperture, to insert the check pin therein, on both the cylindrical knuckle part and the rod member engaged within the cylindrical knuckle part; and for fixing the rod member securely within the cylindrical knuckle part by inserting the check pin into the apertures, so that a lot of labour and time is needed for fabricating a hinge. Furthermore, such a hinge thus produced is apt to lack solidity in structure because of the fact that ~0 the rod member is often sub~ected to be loosely surrounded

against the main body (5) of the hinge leaf to form a cylindrical knuckle part (6) as shown in ~igure 1d;
(E) The wound portion (6) is t~rned down to be dis-placed within the plane of the main body (5) as shown in Figure 1e.
According to the aforementioned method of the present invention, when the cylindrical knuckle part (6) is formed on one side edge of a blank (1) for a hinge leaf, the rod member (3) applicable to either a hinge pintle or a thrust bearing has already been surrounded tightly by the cylindrical knuckle part (6) : along with the cylindrical knuckle part (6) being able to roll up the rod member (3) therein as an internal mold, thereby a steady hinge without locseness can be fabricated economically in less labor and a short period of time.
Figure 2 shows a step of processes for bending one side edge of the blank (1) for a hinge leaf to form a :
slight arc shape in profile as shown in Figure 1b by : 20 means of a lower die (7) and an upper die (8). ~he blank (1) for a hinge leaf is initially placed on the horizontal surface (14) of the lower die in such a manner as indicated by the two dots and dash line that one end (9) of the blank is extended to come in contact with : 25 an upright plane (13) by crossing over a groove (12) formed by a concave arc surface (10) provided on the lower die and an oblique surface (11) extended in upward inclination from the end portion of concave arc surface.
~: After having placed the blank (1) on the lower die~ the upper die (8) is adapted to slide down along the upright -:' ~04s800 plane (13) of the lower die to press one side edge of the blank (1) by the arc-shaped nose (15) of the upper die, thereby the one side edge is subjected to be bent nearly to an arc shape corresponding to the concave groove in profile as indicated by the solid lineO
Figure 3 illustrates a step of processes in series for rolling up the aforementioned bent portion (2) of the blank in a circular shape as shown in Figure 1d by employing a lower die (16) and an upper die (17)o The bent portion (2) formed at one side edge of the blank : welded on the rod member (3) is placed on a semi-circular groove (18) provided on the lower die (16) as indicated by the solid line to set the main body portion (5) of : the blank for a hinge leaf to be upright along a vertical plane (19) of the lower die (16), and the upper end of the blank is pressed by a bottom plane (20) of the upper die (17) which slides downwards so as to form ; a cylindrical knuckle part (6) at the above-mentioned bent portion (2) which is rolled up in a circular shape along the inner profile of the groove (18) as indicated by the chain line.
Figure 4 illustrates a step of processes in series for turning up the main body of the blank at the point A
by amploying an upper die (21) and a lower die (22) so 25 as to displace the aforementioned cylindrical knuckle :
part (6) thus rolled up in a circular shape within the plane of the main body portion (5) for a hinge leaf as shown in Figure 1e. The cylindrical knuckle part (6) is engaged within a semi-circular groove (23) of the lower ~ .
die (22) as indicated by the chain line to render the main - 6 ~

adapted to be engaged within a recess (28) provided on the upper die (21), to keep it from being crushed down.
Some examples for application of the rod member (3) - to either a hinge pintle or a thrust bearing are illust-rated respectively in Figure 5 - Figure 11.
As for a hinge shown respectively in Figure 5 - ~ .
