Abstract
Abstract An improved temperature measuring probe is provided, including a sensing element having a probe head attached at the forward end and a handle connected to the rearward end. The probe is designed for use with an elastic cot designed to fit over the sensing element and to be releasably secured to the handle. To this end a flange extends about the forward portion of the handle. A pair of diametrically opposed slits extend into the handle from the forward end bisecting the flange. The halves of the flange are normally spaced apart a distance sufficient to engage an annular ring at the open end of the associated cot. Upon the application of a sufficient force, the halves of the flange may be shifted toward one aNother to enable the cot ring to override the flange.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
In combination: a measuring probe; a sensing element of said probe, said sensing element comprising an elongated member having a shank portion, a free front end, and a rear end connected to a handle; a handle disposed about portions of said sensing element; securing means coupled to said handle adapted to releasably secure a protective cot about said sensing element, said securing means including a flange disposed about said handle, said flange being transversely shiftable with respect to said shank; means connected to said securing means for enabling the shifting of said securing means between a cot retaining position and a cot release position; a protective cot adapted for placement over said sensing element, said cot including an elongated member formed of an elastic material, a closed front end of said elastic member, an open rear end of said elastic member; and, a relatively rigid annular ring disposed about said open end defining an opening into the interior of said cot, the inside diameter of said ring being substantially equal to the crosssectional dimension of said flange measured when said flange is in said release position.
Claim 2
Dependent Claim
186 words
In combination: a measuring probe; a sensing element of said probe, said sensing element comprising an elongated member having a shank portion, a free front end, and a rear end connected to a handle; a handle disposed about portions of said sensing element; securing means coupled to said handle adapted to releasably secure a protective cot about said sensing element, said securing means including a flange disposed about said handle, said flange being transversely shiftable with respect to said shank; means connected to said securing means for enabling the shifting of said securing means between a cot retaining position and a cot release position; a protective cot adapted for placement over said sensing element, said cot including an elongated member formed of an elastic material, a closed front end of said elastic member, an open rear end of said elastic member; and, a relatively rigid annular ring disposed about said open end defining an opening into the interior of said cot, the inside diameter of said ring being substantially equal to the crosssectional dimension of said flange measured when said flange is in said release position.
Claim 3
Dependent Claim
79 words
The invention in accordance with claim 1 wherein said handle comprises a generally elongated member coaxial with said sensing element, a front section of said handle extending over portions of said shank, a recess extending about said handle front section proximal the front end of said handle defining said flange and a pair of diametrically opposed slits in said handle front section extending rearwardly from said handle front end whereby to separate said handle front section into two halves.
Claim 4
Dependent Claim
55 words
The invention in accordance with claim 2 wherein said handle front section tapers outwardly from said handle front end to said flange and the diameter of said handle front end is less than the inside diameter of said cot ring and the diameter of said flange is greater than the inside diameter of said ring.
Claim 5
Dependent Claim
56 words
The invention in accordance with claim 2 wherein the length of said cot body portion when relaxed is less than the distance measured from the front end of said sensing element to the handle flange and wherein said cot is formed of a material sufficiently elastic, to enable said cot to be stretched to said distance.
Claim 6
Dependent Claim
24 words
The invention in accordance with claim 1 wherein said relatively rigid annular ring comprises the open end of said cot rolled over on itself.
Claim 7
Dependent Claim
148 words
A measuring probe for association with a removable elongated cot formed of an elastic material having a closed front end, an open rear end and a relatively rigid annular ring disposed about said open end defining an opening into the interior of said cot, said probe comprising: a sensing element including an elongated member having a shank portion, a free front end containing a proBe head, and a rear end connected to a handle; a handle connected to one end of said element; securing means coupled to said handle adapted to releasably secure said cot about said sensing element, said securing means including a recessed portion extending about said handle defining a flange, said flange being transversely shiftable with respect to said shank; and means connected to said securing means for enabling the shifting of said securing means between a cot retaining position and a cot release position.
Claim 8
Dependent Claim
148 words
A measuring probe for association with a removable elongated cot formed of an elastic material having a closed front end, an open rear end and a relatively rigid annular ring disposed about said open end defining an opening into the interior of said cot, said probe comprising: a sensing element including an elongated member having a shank portion, a free front end containing a proBe head, and a rear end connected to a handle; a handle connected to one end of said element; securing means coupled to said handle adapted to releasably secure said cot about said sensing element, said securing means including a recessed portion extending about said handle defining a flange, said flange being transversely shiftable with respect to said shank; and means connected to said securing means for enabling the shifting of said securing means between a cot retaining position and a cot release position.
Claim 9
Dependent Claim
79 words
The invention in accordance with claim 6 wherein said handle comprises a generally elongated member coaxial with said sensing element, a front section of said handle extending over portions of said shank, a recess extending about said handle front section proximal the front end of said handle defining said flange, and a pair of diametrically opposed slits in said handle front portion extending rearwardly from said handle front end whereby to separate said handle front section into two halves.
Claim 10
Dependent Claim
55 words
The invention in accordance with claim 7 wherein said handle front section tapers outwardly from said handle front end to said flange and the diameter of said handle front end is less than the inside diameter of said cot ring and the diameter of said flange is greater than the inside diameter of said ring.
