Abstract
Abstract Structure for locking a latching mechanism provided for controlling the opening of a range oven door selectively closing an oven cavity, so as to prevent the opening thereof when the oven cavity is at a high temperature such as during a pyrolytic self-cleaning operation. The locking device includes a thermal sensor which is caused to be disposed in accurate correlated relationship to the oven wall outwardly thereof as a result of a housing associated with the thermal sensor being secured to the oven wall. Resultingly, the sensor is retained in accurate preselected heat transfer association with the oven cavity while being free of exposure to fumes and gases generated in the oven cavity.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
In a latching mechanism having a latch assembly, locking means for locking the latch assembly, a heat sensor, mounting bracket means for supporting the sensor in the mechanism, and means responsive to the sensor for operating the locking means as a result of the sensor sensing a preselected high temperature of an adjacent wall, the improvement comprising: a cover housing said sensor and having a force transfer portion engaging said mounting bracket means; and means for securing said cover to said adjacent wall with the force transfer portion, as a result of the cover being secured to said wall, urging said mounting bracket means to a preselected disposition relative to said wall to dispose said heat sensor supported by the mounting bracket means in a preselected thermal transfer spaced relationship to said wall for causing operation of the locking means in accurate correlation with the wall temperature.
Claim 2
Dependent Claim
147 words
In a latching mechanism having a latch assembly, locking means for locking the latch assembly, a heat sensor, mounting bracket means for supporting the sensor in the mechanism, and means responsive to the sensor for operating the locking means as a result of the sensor sensing a preselected high temperature of an adjacent wall, the improvement comprising: a cover housing said sensor and having a force transfer portion engaging said mounting bracket means; and means for securing said cover to said adjacent wall with the force transfer portion, as a result of the cover being secured to said wall, urging said mounting bracket means to a preselected disposition relative to said wall to dispose said heat sensor supported by the mounting bracket means in a preselected thermal transfer spaced relationship to said wall for causing operation of the locking means in accurate correlation with the wall temperature.
Claim 3
Dependent Claim
20 words
The latching mechanism of claim 1 wherein said mounting bracket is clamped between said force transfer portions and said wall.
Claim 4
Dependent Claim
21 words
The latching mechanism of claim 1 wherein said securing means comprises means for urging said cover into engagement with said wall.
Claim 5
Dependent Claim
32 words
The latching mechanism of claim 1 wherein said cover cooperates with said wall when secured thereto by said securing means to define a heat transfer space in which said sensor is disposed.
Claim 6
Dependent Claim
44 words
The latching mechanism of claim 1 wherein said cover cooperates with said wall when secured thereto by said securing means to define a heat transfer space in which said sensor is disposed, said mounting bracket extending through said space into engagement with said wall.
Claim 7
Dependent Claim
152 words
In a latching mechanism having locking means, a heat sensor mounting bracket means for supporting the sensor in the mechanism, and means responsive to the sensor for operating the locking means as a result of the sensor sensing a preselected high temperature of an adjacent wall, the improvement comprising: wall means having a concave portion enclosing said sensor and defining force transfer means for engaging said mounting bracket means, and a securing portion projecting from said concave portion; and means for securing said securing portion to said wall with the force transfer means as a result of the wall means being secured to said wall urging said mounting bracket means into a preselected abutment with said wall to dispose said heat sensor supported by the mounting bracket means in a preselected thermal transfer spaced relationship to said wall for causing operation of the locking means in accurate correlation with the wall temperature.
Claim 8
Dependent Claim
152 words
In a latching mechanism having locking means, a heat sensor mounting bracket means for supporting the sensor in the mechanism, and means responsive to the sensor for operating the locking means as a result of the sensor sensing a preselected high temperature of an adjacent wall, the improvement comprising: wall means having a concave portion enclosing said sensor and defining force transfer means for engaging said mounting bracket means, and a securing portion projecting from said concave portion; and means for securing said securing portion to said wall with the force transfer means as a result of the wall means being secured to said wall urging said mounting bracket means into a preselected abutment with said wall to dispose said heat sensor supported by the mounting bracket means in a preselected thermal transfer spaced relationship to said wall for causing operation of the locking means in accurate correlation with the wall temperature.
Claim 9
Dependent Claim
22 words
The latching mechanism of claim 6 wherein said securing portion comprises a pair of legs at opposite portions of the concave portion.
Claim 10
Dependent Claim
28 words
The latching mechanism of claim 6 wherein said concave portion defines end portions and said securing portion comprises a pair of legs on each of said end portions.
Claim 11
Dependent Claim
43 words
The latching mechanism of claim 6 wherein said concave portion defines end portions and said securing portion comprises a pair of legs on each of said end portions, each leg defining an integral female means for secured relationship with a male screw element.
Claim 12
Dependent Claim
62 words
The latching mechanism of claim 6 wherein said mounting bracket means comprises a bracket having a portion received within said concave portion of the wall means, a first end portion extending through the wall means, and a second end portion projecting from the concave portion toward said wall and comprising the portion of the bracket means urged into abutment with said wall.
Claim 13
Dependent Claim
83 words
The latching mechanism of claim 6 wherein said mounting bracket means comprises a bracket having a portion received within said concave portion of the wall means, a first end portion extending through the wall means, and a second end portion projecting from the concave portion toward said wall and comprising the portion of the bracket means urged into abutment with said wall, said portion within the concave portion of the wall means defining a force receiving portion engaged by said force transfer means.
Claim 14
Dependent Claim
91 words
The latching mechanism of claim 6 wherein said mounting bracket means comprises a bracket having a force receiving portion within said concave portion of the wall means, a first end portion extending through the wall means, and a second end projecting from the concave portion toward said wall and comprising the portion of the bracket means urged into abutment with said wall, said force receiving portion and said force transfer means respectively defining confronting surfaces brought into facial abutment as a result of the wall means being secured to said wall.
