Definitions

  • Portable wood burning stoves are used in camping for heat and cooking.
  • large portable firepits are used for example in residential back yards for recreation, to provide outdoor heat, and to support limited cooking such as marshmallow roasting.
  • Figure 3 is an exemplary representation of a fire grate for a wood burning fire pit, in accordance with at least one embodiment of the present disclosure.
  • the combustion fire pit 150 includes a top portion 152, a bottom portion 154, and a middle portion 156.
  • the firepit 150 further includes an inner wall or inner body 110, an outer wall or outer body 120, a connecting ring 125 located in the top portion 152 of the fire pit 150 and attached to or formed as a single piece with the inner body 110 and the outer body 120, and a cavity or burn chamber 190 defined by an inwardly facing surface of the inner body 110, within which the fire grate 100 is positioned.
  • the fire pit 150 further includes a top lip 115 attached to or formed as a single piece with either of the inner body 110 or outer body 120.
  • the fuel 160 combusts into ash 162, which falls through the fire grate 100 into the ash pan 180.
  • the fire grate 100 can be removed from the fire pit 150 by lifting it vertically upward, in a direction parallel to axis 270, through the cavity or burn chamber 190. This permits user access to the ash pan 180, which can then also be removed from the fire pit by lifting vertically through the cavity or bum chamber 190.
  • the ash pan 180 may then be emptied and optionally cleaned.
  • the fire grate 100 may also optionally be cleaned, and then the ash pan 180 and fire grate 100 returned into the fire pit 150 as shown in Figure 1.
  • the feet 440 of the ash pan 180 rest on the bracing tray bottom 475 such that they are nested against the centering rim 480. This permits both the self-centering of the ash pan 180 within the fire pit 150, and the maintenance of air gap 178 between the ash pan 180 and the bracing tray 175, with minimal effort or precision required on the part of the user.
  • FIG 6 is a perspective view of another embodiment of an ash pan 180 for a wood burning fire pit, in accordance with at least one embodiment of the present disclosure.
  • the ash pan 180 includes a top lip 410, an upward- embossed central hub 420, three radial stiffening arms 430, and three downward-embossed feet 440 disposed at or near the outer edge of the ash pan bottom.
  • the ash pan 180 rests on the bottom of the bracing tray, such that the feet 440 of the ash pan 180 are nested against a centering feature of the bracing tray.
  • FIG. 7 is a perspective view of another embodiment of an ash pan 180 for a wood burning fire pit, in accordance with at least one embodiment of the present disclosure.
  • the ash pan 180 does not include feet that rest on the bottom of the bracing tray 175. Rather, the ash pan 180 includes a lip 710 designed to hang from a recessed ring 730 in the rim 720 of the bracing tray 175.
  • a central feature, cone, or tower 740 rises up from the base 704 of the ash pan, and includes a cap 750 that may for example be used as a handle to lift the ash pan 180 out of the fire pit 150, or return the ash pan 180 into the fire pit 150.
  • ventilation holes 760 are provided both in the side wall 702 of the ash pan 180 and in the central tower 740.
  • the size, shape, and positioning of the tower 740, cap 750, or ventilation holes 760 may be different than shown in Figure 7.
  • the number of ventilation holes may also be different, ranging from one ventilation hole to a large plurality of ventilation holes.
  • Figure D is a perspective top view thereof
