  • Another example is any such cookware vessel, where the handle is configured to detach from the vessel without the user manually moving the actuator.
  • a cookware vessel includes a vessel, a bracket, and a detachable handle.
  • the vessel has a bottom portion surrounded by a substantially upright sidewall that terminates at a rim to define an interior volume for holding a food item.
  • the bracket is coupled to an exterior of the substantially upright sidewall adjacent to the rim.
  • the bracket has two vertically spaced apart rods that extend horizontally along the bracket. The two rods include an upper rod and a lower rod.
  • the handle includes a grip portion, a coupling fixedly attached to the grip portion, an actuator rotatingly coupled to the handle, and a spring coupled to the actuator.
  • the coupling has a channel and an indented bottom portion.
  • a cookware article is configured with a bracket on an exterior side wall for receiving a removable handle.
  • the bracket has an interior channel that extends from an opening in an underside that receives an arm or plate of the U-shaped coupling.
  • the U-shaped coupling on the end of an elongated plate that extends into a grip portion of the handle.
  • the elongated plate has a concave depression on an underside that provides a guiding surface for the elongated rod to translate along the plate such that a beveled end thereof can extend through penetration in the U-shaped coupling to secure the coupling within the bracket.
  • Another example is any such cookware vessel, where the handle is configured to be attached to the vessel without the actuator being manually rotated in the second direction by the user.
  • a detachable handle for a cooking vessel includes a grip portion, a coupling, an actuator, and a spring.
  • the coupling is attached, directly or indirectly, to the grip portion, and has a channel configured to surround at least a portion of an upper partial geometric surface of a bracket attached to the cooking vessel when positioned against the upper partial geometric surface.

  • a cookware vessel (such as a pot or a pan) includes a handle that is permanently attached to the cookware vessel.
  • Other traditional cookware vessels include a handle that is detachable from the cookware vessel.
  • Such traditional detachable handles may be deficient.
  • such traditional detachable handles require considerable mechanical complexity, as well as a particular structure on the cookware vessel for engaging the detachable handle. This particular structure can be an outward extending flange with a lockable mating feature designed to engage an internal fixture of the detachable handle.
  • a problematic deficiency in traditional detachable handles is the lack of a snug engagement with the receiving component on the cookware vessel.
  • cookware vessel 1000 may provide an easier and more reliable means for attachment to the bracket 120 of the cookware vessel 100.
  • a user of cookware vessel 100 only utilizes the actuator 260 to remove the handle 200 from the vessel 100, not to attach the removed handle 200 to the vessel 100.
  • the user is required to manually engage an actuator to attach the handle to the cookware vessel.
  • these traditional detachable handles are more complicated, and require a user to simultaneously perform multiple functions in order to re-attach the detachable handle.
  • the 121 includes an aperture 122 positioned in a location above the lower opening 120o.
  • the handle 200 does not include the elongated rod 240. Instead, the actuator 260 of the handle 200 can engage (e.g., clip into, clamp onto) a portion of the bracket 120. This may assist in securing the handle 200 to the vessel 100, in some examples.
  • the spring 250 may apply a force to the actuator 260.
  • the spring 250 is a torsion or compression spring.
  • the spring 250 may be positioned at a tilt, as is illustrated in FIGS. HA- HE.
  • the force from the spring 250 may cause the actuator 260 to rotate forwards (i.e., to the left in FIGS. 11A-11E) in a counterclockwise direction. This rotation may allow the actuator 260 to engage (e.g., clamp onto, clip into) a portion of the bracket 120, so as to assist in securing the handle 200 to the vessel 100.
  • the force from the spring 250 may also resist rotation of the actuator 260 backwards (i.e., to the right in FIGS. 11A-11E) in a clockwise direction.
  • the actuator 260 is configured to engage (e.g., clip into, clamp onto) a portion of the bracket 120. This may assist in securing the handle 200 to the vessel 100, in some examples. For example, it may lock the handle 200 in place with the vessel 100, thereby eliminating (or reducing) any “play” between the two components.
  • the upward movement of the handle 200 causes the actuator 260 to move upward over the upper edge 128 of the bracket 120.
  • the force from the spring 250 may rotate the actuator 260 forward (i.e., to the left in FIGS. 11D-11E) in a counterclockwise direction.
  • the actuator 260 may engage (e.g., clip into, clamp onto) the upper edge 128 of the bracket 120, so as to assist in securing the handle 200 to the vessel 100.
  • the rotational clamping motion of the actuator 260 may cause the handle 200 to continue to attach to the vessel 100 even if the user stops pushing the handle 200 upwards, as is discussed above.
  • the handle 200 may include an upward and forwardfacing shaft 279 positioned within a cavity in the handle 200.
  • the shaft 279 may center and stabilize the position of the spring 250.
  • the actuator 260 may have complimentary extending shaft 281 to center and stabilize the other side of the spring 250.
  • the actuator 260 may include one or more rotational couplings 265 that rotatingly couple the actuator 260 to an inside portion of the handle 200, as is illustrated in FIG. 12B.
  • the rotational couplings 265 may rotatingly couple the actuator 260 to a lower shell 232 of the handle 200.
  • the rotational couplings 265 may rotatingly couple the actuator 260 to the back side of the coupling 210.
  • the actuator 260 is discussed above as engaging with a portion of the bracket 120, in some examples, the actuator 260 may alternatively (or additionally) engage with the flange 115 (to which the bracket 120 may be attached or integrated with, as is discussed above).
  • the actuator 260 may rotate relative to the handle 200 (as is discussed above), the coupling 210 may remain fixed in place in the handle 200. As such, any movement of the handle 200 (e.g., upward, downward, rotation) causes the coupling 210 to move with the handle 200.
  • FIGS. 12F-12J illustrate, in schematic cross-sectional elevation views, an example sequence of steps for detaching the handle 200 from the vessel 100.
  • the handle 200 is fully attached to the bracket 120 (and therefore to the vessel 100, not shown).
  • a user presses on the actuator 260, causing it to rotate backwards (i.e., to the right in FIGS. 12F-12J) in a clockwise direction.
  • This causes the hooks 268 to lift upwards (by also rotating backwards) so as to disengage from the lower rod 130b, as is illustrated in FIG. 12G.
  • FIGS. 17A-17C are cross-section views of example movements of the handle 200 and the components thereof for attaching the handle 200 to the vessel 100.
  • FIGS. 18A and 18B are front and rear elevation views of the bracket 120 isolated from the vessel 100 and the handle 200.
  • FIGS. 19A- 19D are various views of an example spring plate 290, in which FIG. 19A is a perspective view, FIG. 19B is a side elevation view showing the spring plate 290 disposed in the bracket 120, which is shown in cross-section view with hatching, FIG. 19C is a front elevation view, and FIG. 19D is a top plan view thereof.
  • FIGS. 20A and 20B are cross-sectional elevation view of examples of the bracket 120 attached to a vessel 100 having an outward sloping side wall.
  • FIG. 20A and 20B are cross-sectional elevation view of examples of the bracket 120 attached to a vessel 100 having an outward sloping side wall.
  • FIGS. 18A and 18B illustrate an example of the bracket 120 in isolation from the vessel 100.
  • FIG. 18A is a front elevation view of the bracket 120 in which the partial geometric surfaces 131 are visible
  • FIG. 18B is a back elevation view of the bracket 120.
  • the bracket 120 includes four opposing depressions 1221, in the form of vertical indents that are spaced apart in the area in-between the upper partial geometric surface 131a and the lower partial geometric surface 131b.
  • the depressions 1221 may present as projections that extend outward from the rear side of the bracket 120, as is illustrated in FIG. 19B.
  • FIGS. 20A and 20B illustrate additional examples for how the bracket 120 may be attached to vessel 100 when the sidewall 102 of the vessel 100 slopes outward.
  • the bracket 120 may be integrated with or positioned on an external side of a flange 115 that is directly connected to the sidewall 102 of the vessel 100 (such as with bolts, welds, or rivets).
  • the bracket 120 may be formed with a sloping rear wall 120r that matches the shape of the sidewall 102. This sloping rear wall 120r may allow the upper partial geometric surface 131a to be disposed over the lower partial geometric surface 131b, so that they both extend to the same (or similar) horizontal position (as is illustrated by the vertical line in FIG. 20B).
  • the hooks 268 are on opposing arms 2681 that project forward from the lower portion of the actuator body 2601 (see FIG. 13B).
  • the channel 218 of the coupling 210 is disposed medially with respect to a gap in-between the spaced apart hooks 268 of the actuator 260.
  • the actuator 260 (including the hooks 268) can rotate about the lower pin 278b, while the orientation of the coupling 210 (with the channel 218) is fixed by the upper pin 278a and rails 207. As such, the actuator 260 rotates with respect to the coupling 210 (and with respect to the handle 200).
  • the spring plate 290 may be affixed to the underside of the narrow lower portion 2172 of the coupling 210.
  • a screw may be inserted through both the hole 2902 in the base of the spring plate 290 and also a corresponding threaded recess in the coupling 210 (not shown).
  • the bottom of the spring plate 290 and the opposing sides (surrounding the bottom) of the spring plate 290 are configured to snugly receive the opposing sides and bottom of the narrow lower portion 2172 of the coupling 210. This may assist in affixing the spring plate 290 to the underside of the narrow lower portion 2172 of the coupling 210.
  • the cavity 205 and support surface 234 of the handle 200 may be an integral monolithic member (as is illustrated in FIG. 23 A), onto which the grip member 230 is over molded from thermoplastic or thermosetting resins (as is illustrated in FIG. 23B).
