Definitions

  • the prior art includes U.S. Pat. No. 5,931,150 issued on Aug. 3, 1999 to Bowen et al.
  • the apparatus described therein includes respective circular discs each having a radially extending slot that extends from the center of each disc to the periphery of the disc.
  • One such disc is placed behind each knob by aligning the radial slot thereof with the shaft and sliding the disc along the extent of the radial slot until the center of the spacer substantially encircles the shaft that carries the knob.
  • the thickness of the disc is sufficient to prevent axial travel of the knob and thus prevent axial travel of the shaft and discharge of flammable gas.
  • the present invention is generally directed to safety apparatus for gas stoves. More particularly, the present invention is directed to apparatus to prevent inadvertent discharge of flammable gas from a gas stove. Even more particularly, the present invention is directed to preventing safety hazards inherent in the inadvertent discharge of flammable gas from a gas stove.
  • knobs to control the flow of gas to individual burners as well as the oven.
  • the knobs are disposed on respective shafts near the intersection of the front face of the stove and the top face of the stove.
  • an axial force is required to deep press each knob before the knob can be rotated clockwise to initiate gas flow to the respective burner or oven.
  • This construction is intended to prevent gas flow into the environment of the stove. In practice merely applying an axial force to any individual knob initiates gas flow without any rotation of the knob. Accordingly, there may be inadvertent discharge of gas or other room in which the gas stove is disposed if someone leans against any one of the respective knobs.
  • Disadvantages of this construction include the necessity for placing a separate disc behind each of the knobs. In the event any such disc falls off and thus is not behind each of the knobs there is a vulnerability to inadvertent release of flammable gas. Human error is also a vulnerability because it is relatively easy to inadvertently not place a spacer of this type behind each of the required knobs.
  • the shortcomings of the prior art are overcome and additional advantages are provided through a safety apparatus for prevention of inadvertent discharge of flammable gas by a gas stove having an array of knobs constructed to allow discharge of flammable gas to respective burners subsequent to depression of one or more knobs.
  • the apparatus includes a safety apparatus having a first planar member having an edge; the safety apparatus includes a plurality of recesses extending from the edge. Each of the recesses is dimensioned for passage proximate to respective shafts carrying respective knobs on the associated stove.
  • the first planar member has a thickness small enough to fit intermediate the backs of each of the knobs and a thickness large enough to prevent axial movement of the knobs that is sufficient to allow discharge of flammable gas.
  • a plurality of the recesses have an identical shape.
  • One of the recesses may have a generally rectangular shape.
  • a plurality of the recesses may be arch shaped.
  • the safety apparatus may further include a second planar member fixed to the first planar member.
  • the second planar member may be disposed in substantially perpendicular relationship to the first planar member. An edge of the second planar member may be rectilinear.
  • FIG. 1 is an isometric view of a portion of conventional gas stove showing the relationship between the gas burners and the knobs that control the flow of gas to the burners;
  • FIG. 2 is an isometric view of one embodiment of the safety stop apparatus in accordance with the present invention.
  • FIG. 3 is an isometric view of the same embodiment of the safety stop apparatus shown in FIG. 2 illustrating the cooperation with knobs of a stove.
  • a conventional gas cooking stove 10 typically has a plurality of burners 12 disposed on the top surface 14 thereof in addition to a plurality of knobs 16 often disposed at the top of the front surface thereof.
  • the knobs 16 are carried on respective shafts.
  • the typical gas fired stove includes a mechanism that allows the discharge of flammable gas at one of the respective burners 12 when one of the knobs 16 is depressed.
  • the control mechanism requires depression of each of the knobs 16 before that knob 16 may be rotated clockwise to a position suitable for cooking throughout a finite cooking period.
  • knob 16 Although it is necessary to depress a knob 16 before the mechanism allows rotation of the knob 16 to a position suitable for passage of gas over a finite cooking period, typical burner and oven controls allow passage of flammable gas to the burner merely upon depression of one of the knobs and 16 .
  • the safety apparatus 20 in accordance with one form of the present invention is shown in greater detail in FIG. 2 .
  • the apparatus 20 includes a virtually extended elongated plan 22 having a thickness that is small enough to fit between the front of the stove and the rear of the respective knobs 16 as well as thick enough to limit the axial movement of the shaft mounting the respective knobs sufficiently to prevent any possibility of discharge of flammable gas.
  • the flanged 22 is provided with U-shaped openings 24 for cooperation and engagement with respective shafts carrying respective knobs.
  • the apparatus 10 includes an opening 26 that is generally rectangular.
  • the opening 26 is intended for use with a stove 10 having a central knob intended for control of an oven.
  • the alternate generally rectangular shape allows for clearance with respect to a screw or any other obstruction that is part of the stove 10 and which is disposed above any knob.
  • the generally rectangular contour is proximate to a central knob within the array of knobs on the front of the stove 10 .
  • the apparatus 20 includes a second flanged 28 which in the illustrated preferred embodiment is generally horizontal and thus perpendicular to the generally vertical flanged 22 .
  • the generally horizontal flanged 28 is convenient for a user to grasp both when the flanged 22 is being placed in the safety position intermediate the back of the knobs 16 and the front of the stove 10 or being removed from the position intermediate the back of the knob 16 and the front of the stove 10 .
  • Other embodiments may have the first flanged 22 and the second flanged 28 disposed in coplanar relationship.
  • the apparatus of the present invention may be manufactured from a wide variety of materials including but not limited to plastic, cardboard, metal and/or wood.
