Definitions

  • Self-latching hinges have gained wide spread acceptance in the building industry for the installation of cabinet doors and the like. Such hinges include a spring biased latching mechanism which retains the cabinet door closed without the need for a separate latch. Thus use of self-latching hinges not only does away with the cost of the latch hardware itself, but also eliminates the even greater labor expense associated with installation of the latch.
  • Hinges of the type just described suffer severalshortcomirigs.
  • the need for a decorative cover complicates assembly and hence increases hinge cost.
  • the spring wire sections extending from either side of the roller tend to slip out from the front of the ears retaining the spring. This is so because as the hinge is opened, a component of force is exerted on the roller by the notch edge in a direction away from the leaf knuckles. This force component is in just the proper direction to work the spring out from under the ears.
  • the ears must be relatively long to cover both the front and rear spring wire sections, and will exhibit some inherent flexure.
  • FIG. 1 is a front elevation view of the inventive selflatching hinge, shown in the closed position.
  • FIG. 2 is a transverse sectional view of the hinge of FIG. 1, as seen generally along the line 2--2 thereof, a cabinet door and frame being shown in phantom.
  • FIG. 3 is a side elevation view showing the ears and tabs supporting the pressure roller and spring assembly
  • FIG. 4 is a perspective view of the hinge leaf to which the roller and spring assembly is attached.
  • the hinge 10 includes a first hinge leaf ll pivotallyconnected to a second hinge leaf 12 by means of 'a hinge pin 13. As illustrated in FIG. 2, and the hinge l0 advantageously may be used to attach a cabinet door 14 or the like to a door frame member -15.
  • the hinge 10 functions to maintain the door 14 closed without the need for separate latch hardware.
  • the door 14 may be fastened to the hinge 10 by the use of screws 16 extending through the openings 17 in an attachment plate 18 forming part of the hinge leaf 1].
  • Extending from one edge of the plate 18 is an offset section 19 of generally L-shaped cross-section which seats within the recessed edge 14a of the door 14.
  • the hinge leaf 11 also includes a spaced pair of hinge knuckles 21, 22 which project forwardly of the plate 18 from the end of the offset section 19.
  • the terminal ends of the knuckles 21, 22 are curled to form a pair of spaced, coaxially aligned bearing sleeves 23, 24 which receive the hinge pin 13.
  • the hinge leaf 12 includes a decorative back plate 26 which may befastened to the door frame 15 by means of screws 27 extending through a pair of mounting holes 28. Extending forwardly from the back plate 26 is a single hinge knuckle 29 the terminal end of which is curled to form a bearing sleeve 30. As shown in FIGS. 1 and 3, the bearing sleeve 30 is situated between, and in coaxially alignment with the sleeves 23, 24 of the other hinge leaf 1 1, so as to engage the central section of the hinge pin 13.
  • the central portion of the sleeve 30 (FIGS. 2 and 3) does not completely encircle the hinge pin 13, but rather defines a notch 31 having a notch edge 32 parallel to the hinge pin 13.
  • the roller 34 (FIG. 3), which may be fabricated of a hard plastic material, surrounds the central section 36 of the spring 35.
  • the wire portions of the spring 35 extending in either direction from the central section 36 define forward legs 37, 38 the ends of which are doubled back to define rear legs 39, 40. This shape results in a spring 35 capable of exerting considerable biasing force on the roller 34.
  • each bearing sleeve 23, 24 is incompletely curled to form the ears 42, 43 in a plane substantially parallel to the hinge knuckles 21, 22 and spaced therefrom by a distance approximately equal to spring forward legs 37, 38.
  • the tabs 44, 45 comprise segments of the hinge leaf 35 to work loose or become dislodged. Moreover, the ears 42, 43 function to insure that the spring 35 will remain firmly within the plane producing maximum force against the notch edge 32 of the leaf member 12.
  • the inventive self-latching hinge 10 is not only attractive, but due to the action of the novel bearing sleeve projecting ears 42, 43 provides a hinge of signifi- 11 extending from theoffset section 19 in a direction parallel to the attachment plate 18.
  • the terminal ends 44a, 45a of the tabs 44, 45 are bent forwardly of the attachment plate 18, in a plane substantially parallel to that defined by the ears 42, 43.
  • the tabends 44a, 45a also are spaced from the hinge knuckles 21, 22 by a distance equal to the thickness of the wire forming the spring 35.
  • the tabs 44, 45 respectively retain in place the spring rear legs 39, 40.
  • the spring 35 is maintained firmly in a plane substantially parallel to the hinge pin 13.
  • the force produced by the spring 35 is exerted in just the direction necessary to maximize the latching capability of the hinge 10.
  • the roller 34 When the hinge 10 is open (FIG. 3), the roller 34 bears against the exterior surface a of the sleeve 30, thereby compressing the spring 35. As the door 14 and hinge 10-are rotated toward the closed position (FIG. 2), the roller 34 begins to engage the notch '31. When this occurs, the force of the spring presses the roller 34 against the notch edge 32 to force the hinge 10 into the latched position. The pressure exerted by the spring 35 and roller 34 against the notch 31 thereafter maintains the hinge closed. Subsequently, the hinge 10 may be opened by rotating the door 14 and the hinge leaf 11 with sufficient effort to overcome the latching force" of the spring 35.
  • a self-latching hinge comprising:
  • a unitary wire spring having a central section extending through said roller, and having forward legs extending in opposite directions from said central section and doubled back to define rear legs,
  • said first hinge leaf being unitary and including
  • each knuckle being curled to form a bearing sleeve, said sleeves being coaxially aligned and receiving said hinge pin,
  • each sleeve being incompletely curled and extending rearwardly in generally spaced parallel relationship with a respective knuckle to form an ear retaining a respective forward leg of said spring
  • each tab extending generally parallel to said plate from adjacent the rear ends of said spaced knuckles, the terminal end of each tab being bent forwardly of said plate into generally coplanar relationship with said ears to retain a respective rear leg of said spring,
  • said second hinge leaf being unitary and including
  • a selflatching hinge of the type having a pair of hinge leaves pivotally connected by a hinge pin, one of said hinge leaves having a spaced pair of knuckles the terminal ends of which are curled to form bearing sleeves, said hinge having a doubled back unitary wire roller-biasing spring retained against the knuckles of said one hinge leaf by ears projecting rearwardly from the bearing sleeves of said leaf and by tabs extending parallel to the leaf attachment plate and bent forwardly into a plane parallel to said ears.
  • a self-latching hinge according to claim 5 wherein said one leaf includes an offset section having first and second portions disposed at right angles, said first portion extending perpendicularly to said attachment plate, said knucklesextending perpendicularly to said second portion, said tabs extending from and coplanar with said second portion between said knuckles.
  • a self-latching hinge according to claim 7 including a cylindrical roller supported by the central section of said unitary wire spring, the forward legs of said spring extending from said central section being retained against said knuckles by said ears, the doubled back rear legs of said spring being retained by said tabs.
