Stovetop fire suppressor mounting device and method
View Patent ↗A mounting device and method of mounting an automatic stovetop fire suppressor are provided herein. Stovetop fires are a well-known residential and commercial hazard. Common parts are utilized across the stovetop fire suppressors employed in different stovetop configurations, reducing inventory count. The mount design can be automated for greater efficiency of time and labor and may provide increased production or throughput. A magnet is attached at the factory for the vent hood product, eliminating the need for such assembly by an end user. This attachment also alleviates loss or misplacement of the magnet during unpacking or installation. A threaded insert is staked to the fire suppressor can and affords reliable retention of the magnet to the fires suppressor can. The present designs enables formation of a consistent vent area in the fire suppressor can.
1. A mounting device for a stovetop fire suppressor, the device comprising:
a threaded insert disposed in a top wall of the stovetop fire suppressor;
a felt washer in juxtaposition with a shoulder of the threaded insert; and wherein,
the threaded insert has a top rim for staking to a top of a stovetop fire suppressor container.
2. A mounting device for a stovetop fire suppressor, the device comprising:
a threaded insert disposed in a top wall of the stovetop fire suppressor;
a felt washer in juxtaposition with a shoulder of the threaded insert; and
internal threads in the threaded insert mated with machine screw threads having a major diameter of 0.1112 inches and a pitch diameter of 0.0950 inches.
3. The device according to claim 2 , further comprising:
a stainless steel 18-8 machine screw mated to the internal threads of the threaded insert.
4. The device according to claim 3 , further comprising:
a nylon patch in the threaded portion of the bolt.
5. The device according to claim 4 , further comprising:
the nylon patch minimum length is four thread pitches.
6. A mounting device for a stovetop fire suppressor, the device comprising:
a threaded insert staked to a top of a stovetop fire suppressor container;
a felt washer sandwiched between a shoulder of the threaded insert and an inner side of the top of the stovetop fire suppressor container;
a vent hole in the top the stovetop fire suppressor container, wherein the felt washer covers the vent hole;
a machine screw of 0.11 inch diameter threaded into the internal threads of the threaded insert; and
a magnet housing with a center opening greater than an outer diameter of a shaft of the machine screw and less than the diameter of a head of the machine screw secured to the top of the stovetop fire suppressor container via the machine screw.
7. A method of making a mounting device for a stovetop fire suppressor, the method comprising:
creating a center hole in a top of a stovetop fire suppressor container;
inserting a threaded insert which has a felt washer in juxtaposition with a shoulder of the threaded insert through the center hole; and
mechanically staking a top rim of the threaded insert to an outer side of the top of a stovetop fire suppressor container.
8. The method of making a mounting device according to claim 7 , further comprising:
creating a vent hole in the top of a stovetop fire suppressor container.
9. The method of making a mounting device according to claim 7 , further comprising:
sandwiching a felt washer between a shoulder of the threaded insert and an inner side of a top wall of the stovetop fire suppressor.
10. The method of making a mounting device according to claim 8 , further comprising:
sandwiching a felt washer between a shoulder of the threaded insert and an inner side of a top wall of the stovetop fire suppressor and covering the vent hole with the felt washer.
11. The method of making a mounting device according to claim 7 , further comprising:
machining and tapping a piece of 0.50 inch aluminum bar stock to make the threaded insert.
12. The method of making a mounting device according to claim 11 , further comprising:
machining a chamfer on a top of the threaded insert and on a bottom shoulder of the threaded insert.
13. The method of making a mounting device according to claim 11 , further comprising:
machining a shaft diameter above a shoulder diameter; and
machining an inner and an outer stake rim diameter, respectively, above the shaft diameter.
