Definitions

  • the present invention relates to door handle and spindle assemblies, and particularly, relates to the long term attachment of door handles or knobs to their spindles.
  • door knobs are typically fastened to a door-spindle with a set screw disposed in the shank of the door knob.
  • This set screw has a propensity to loosen after continued use and may eventually fall out enabling the handle to slip off its spindle when one attempts to open the door. This can be an irritating nuisance compounded further by the loss of the set screw.
  • small children can be locked inside a room, panic, and sometimes enter into a state of hysteria when trapped inside a room in which the door handle has slipped off its spindle..
  • a ratchet- enabled door knob including a pawl pivotally mounted in a shank of a door knob; and a biasing element configured to resiliently bias the pawl to engage a toothed door-spindle when the door knob body is mounted on the spindle.
  • the pawl is implemented to releasably engage the spindle.
  • the biasing element includes a coil spring.
  • a door a toothed door-spindle traversing the door; and a door knob mounted on the door-spindle, the door knob having a pawl pivotally mounted in a shank of the door knob, the pawl resiliently biased to releasably engage the toothed-door-spindle when the door knob is mounted on the door-spindle.
  • the biasing element includes a coil spring.
  • a method for construction a door assembly including mounting a toothed door-spindle mounted in a door; and mounting a pivoted pawl configured to releasably secure a door knob to the toothed door-spindle when mounted in a door, the pawl resiliently biased to assume a positon within interdental spaces of the spindle.
  • a method for construction of a door assembly including mounting a toothed door-spindle mounted in a door; sliding a door knob on to the door-spindle, the door knob having a pivotally mounted pawl in a shank of the door knob, the pawl configured to releasably secure the toothed door-spindle; and releasably engaging the door-spindle with the pawl.
  • a method of securing a door knob to a door-spindle including providing a toothed door- spindle; and sliding a ratchet-enabled door knob onto the toothed door-spindle until door knob is releasably secured on the door-spindle.
  • FIGS. 1 and 2 are schematic, cross-sectional side views of a door handle and toothed spindle and pawl coupling in engaged and disengaged states, respectively, according to an embodiment
  • FIG. 3 is a schematic, cross-sectional side view of a variant embodiment of the door handle and spindle assembly depicted in FIGS. 1 and 2, according to an embodiment
  • FIG. 4 is a schematic, cross-sectional side view of a door employing the door handle and spindle assembly depicted in FIGS. 1 and 2 and an additional lock handle and spindle assembly, according to an embodiment
  • FIG. 5 is a schematic, cross-sectional end view of the door knob and spindle assembly depicted in FIG. 4, according to an embodiment.
  • Door assembly refers to the collective set of accessories relating to securing a door in a closed state or freeing the door to assume an open state.
  • Knob body refers the collective unit of the knob and the knob shank.
  • spindle refers to a toothed shaft or bar that attaches to at least one handle and transferring torque to a latch or lock mechanism when a handles is rotated.
  • Pawl refers to a pivoted pin or lever that engages the spindle when disposed in its interdental spaces, according to an embodiment.
  • Knob rose refers to a base structure covering a spindle bore through the door, according to an embodiment.
  • spindle teeth refer to angled or non-angled ridges separated by interdental spaces of the door-spindle.
  • Ringet-enabled knob refers to a door knob configured to releasably engage a toothed-spindle system with a pawl pivotally mounted in the neck or shank of the door knob.
  • FIGS. 1 and 2 are schematic cross-sectional views of a door assembly 1 including a door knob 2, a door knob shank 5, a toothed spindle 3, a resiliently biased pawl 7 configured to releasably engage spindle 3, and knob rose 10, according to an embodiment.
  • knob 2 is securely fastened to spindle 3 by way of pivoted pawl 6 disposed in the interdental spaces 4 of toothed spindle 3 while in an engagement mode.
  • Pawl 6 is pivotally mounted in shank 5 on pin 8 and is biased to assume an engagement position by compression spring 7 also disposed in shank 5, according to an embodiment. Upon application of force "A” pawl 6 pivots around pin 8 and releases spindle 3 so as to enable either removal of knob 2 from spindle 3 as shown by arrow “C” or, alternatively, remove spindle 3 from knob 2.
  • FIG. 3 depicts a variant embodiment of door assembly 1 depicted in FIGS. 1 and 2.
  • This embodiment is implemented with biasing spring 7 and pawl 6 mounted in knob rose 10.
  • Compression spring 7 is constructed from a flexible metallic material; however, it should be noted that other materials providing such functionality are also included within the scope of the present invention.
  • embodiments employing tension springs or leaf springs or other types of recoil mechanisms providing the required biasing of pawl 6 are included within the scope of the present invention.
  • a knob 2 are permanently fastened to spindle 3.
  • engagement of the knob/spindle unit is achieved by a single spindle/pawl coupling whereas in other embodiments in which each knob is releasably attached to the spindle, two spindle/pawl couplings are required to secure handles 2 to spindle 3.
  • the knob/ spindle coupling advantageously provides long-term connection between handle 2 and spindle 3 and eliminates the commonplace complications resulting from a loose or missing set screw as noted above.
  • pawl 6 has an accessible contact surface extending from the shank 5 or knob rose 10, thereby facilitating the application of a release force that may be applied by a user without tools.
  • FIG. 4 depicts a door assembly 1 mounted on a door 11; assembly 1 includes two handles 2 connected by toothed spindle 3 traversing both door 11 and latch mechanism 16, and knob roses 10.
  • pivotally mounted pawl 6 is resiliently biased in an engagement position by compression spring 7.
  • force "A” causes pawl 6 to pivot out of its engagement position, thereby freeing spindle 3 to slide out of knob 2 or alternatively, freeing knob to slide off spindle 3, according to an embodiment.
  • door 11 also includes a lock assembly 17, handle 22, toothed spindle 13 mounted in the lock handle 22 and lock mechanism 18.
  • door lock spindle 13 is secured in lock handle 22 by pawl 16 resiliently biased to engage toothed spindle 13, according to an embodiment.
  • FIG. 5 depicts a schematic end view of the door latch assembly 1 depicted in
  • FIGS. 1-4 Knob 2 and knob rose 10 are implemented as circular structures; but, it should be appreciated that various shapes are included in the scope of the present invention. Further depicted is a toothed spindle 3 and pawl 6 disposed in the interdental space 4 of toothed spindle 3 to such that handle 2 is secured to it as previously noted. It should be further appreciated that spindle 3 embodiments implemented with non-square cross-sections capable of transferring torque to latch mechanisms are included within the scope of the present invention. Spindle teeth 4 are implemented as an alternating series of lateral ridges and grooves in spindle 3 and in certain embodiments span only a fraction of the length of spindle 3 needed to provide the required engagement functionality.
  • Pawl 6 is constructed from a metallic material having sufficient rigidity to secure spindle 3 in place and can withstand the tension applied to knob 2 thought extended use. It should be noted, that various surface geometries of pawl 6 providing the above described engagement functionality are included within the scope of the present invention.
