FIELD OF THE INVENTION
The present invention generally relates to a bracket and pedal system that holds and operates a temporal thermometer without direct hand contact.
BACKGROUND OF THE INVENTION
During early 2020, SARS-CoV-2, also known as the Coronavirus or COVID-19 spread worldwide, requiring countries, states, and individual counties to initiate lockdown procedures to flatten the curve of the pandemic spread. As companies reopened, many businesses began providing initial testing to safely gauge whether employees were healthy and could return to work. They also implemented procedures to test employees as they entered the workplace to ensure that they were symptom-free. Symptoms of a positive COVID-19 patient include a fever. Therefore, taking the temperature of a worker prior to entering the workplace, is a cost-effective measure to prevent increased spread of the virus. Other precautions that were established to help curb the spread of the virus included social distancing and curbside pick-up to encourage less physical contact.
A previous solution to screen employees for COVID-19 has been the installation of thermal camera technology that can detect heat emitted from an individual's body. Major companies such as Amazon, Tyson Foods, and Intel have used these thermal cameras. The camera systems are known in the art and were widely used in Asian airports after the SARS epidemic in 2003. However, these sophisticated camera systems are expensive (between $5,000 and $20,000), and unaffordable by many smaller companies.
One inexpensive option for smaller companies is the use of an infrared temporal thermometer. Temporal artery thermometers—often sold as forehead thermometers—use an infrared scanner to measure the temperature of the temporal artery in the forehead. An advantage of this type of thermometer, in addition to their relatively low cost, is that it can record a person's temperature quickly and is reasonably accurate. In fact, some research suggests that temporal artery thermometers are the most accurate alternative to rectal digital thermometers for taking a child's temperature. A disadvantage, however, is that, in use, someone must hold and operate the thermometer to record the temperature of another. Obviously, it is an added expense to pay someone to record the temperatures of co-workers and visitors.
Thus, there has been a long-felt need for a low-cost apparatus for measuring temperature of employees entering a workplace with a temporal thermometer, while avoiding the need for a person to manually hold the thermometer and take readings, and also avoiding contact with the thermometer by the person whose temperature is being recorded.
SUMMARY OF THE INVENTION
The present invention comprises a holder for a temporal thermometer, having a bracket arranged to hold the thermometer, a lever operatively arranged to depress a button on the thermometer to take a temperature reading, a foot pedal, a cable linking the foot pedal to the lever to activate the thermometer, and a duplex mirror assembly operatively arranged to display the temperature reading.
In an alternative embodiment, the present invention comprises a holder for a temporal thermometer, having a bracket arranged to hold the thermometer, a lever operatively arranged to depress a button on the thermometer to take a temperature reading, a foot pedal, a cable linking the foot pedal to the lever to activate the thermometer, a conduit arranged to cover the cable, and a duplex mirror assembly operatively arranged to display the temperature reading.
In another alternative embodiment, the present invention comprises a holder for a temporal thermometer, having a bracket arranged to hold the thermometer, a lever operatively arranged to depress a button on the thermometer to take a temperature reading, a foot pedal, a cable linking the foot pedal to the lever to activate the thermometer, a flexible conduit arrange to cover the cable, and a duplex mirror assembly operatively arranged to display the temperature reading.
A general object of the invention is to provide an inexpensive holder for a temporal thermometer for quick and easy contactless measurement of employee temperatures in a workplace.
A secondary object of the invention is to provide a holder for a temporal thermometer that may be operated by the person whose temperature is to be recorded without need of another employee to operate the thermometer.
A further object of the invention is to provide a foot operated device for activating a temporal thermometer.
These and other objects, features and advantages of the invention will become readily apparent upon a reading of the following detailed description in view of the drawings and appended claims.

FIG. 10 shows hex head bolt 41 that threadably secures hex standoff 40 to bracket 30.
FIG. 11 is an exploded view of the temporal thermometer holding and duplex mirror assembly.
FIG. 12 is an exploded view of the pedal assembly. Pedal Assembly 14 comprises foot switch base 60, rotatably secured to foot switch lever 61 by pedal shoulder screw 62. Pedal shoulder screw 62 rotatably secures foot switch base 60 to foot switch lever 61 and is threadably secured by pedal flange lock nut 63. Foot switch lever 61 contains an aperture operatively arranged to accept cable 16. Cable 16 has cable anchor 70 fixed to the distal end of cable 16 operatively arranged to prevent the distal end of cable 16 from being removed from foot switch lever 61 aperture. Pedal carriage bolt 65 is operatively arranged to pass through substantially centrally disposed apertures on foot switch base 60 and foot switch lever 61. Pedal carriage bolt 65 is threadably secured to foot switch lever 61 by a pair of pedal hex nuts 64. Conduit 15 is secured to foot switch base 60 by way of pedal EMT fitting 66.
FIG. 13 is a perspective view of an alternative embodiment of the present invention's conduit fitting. An alternative conduit fitting may include flexible conduit 27 that is operatively arranged to house cable 16. Flexible conduit 27 may be used to allow for ease of shipping as it does not require specially-fit packaging to accommodate long rigid conduit 15, shown in FIGS. 1 and 3-12, described supra.
The following description should be read in view of FIGS. 1-13 and the respective description supra. It should also be appreciated that the following description applies to all embodiments of the invention.
To engage thermometer 12 to take a temperature a user first depresses pedal carriage bolt 65. Carriage bolt 65 rotates foot switch lever 61. Carriage bolt 65 is not threadably secured to foot pedal base 60 aperture and moves through the aperture when depressed, substantially functioning as a button. When foot switch lever 61 rotates, cable 16 is pulled in the downward direction from cable anchor 70 moving with foot switch lever 61.
The downward movement of foot switch lever 61 engages trigger bar 50 by the downward motion of cable 16. Trigger bar 50 and trigger 13 rotate about steel shoulder screw 19 to engage thermometer button 17 to activate thermometer 12. A user continues to depress pedal carriage bolt 65 until they have recorded the temperature that is reflected back to the user by duplex mirror assembly 18.
When a user has completed a temperature reading and releases pedal assembly 14 pedal carriage bolt 65, extension spring 52 pulls cable 16 in a vertical direction to maintain a substantially level position of trigger bar 50 that releases trigger 13 from depressing thermometer button 17.
