Claim 12

A single use disposable vaginal speculum of a synthetic resin material comprising in combination a. a first frame member forming a hollow handle part and a lower duckbill part, b. a means frame member forming an elongated adjusting section and an upper duckbIll part, c. said elongated adjusting section being positioned in sliding coaxial relationship in said hollow handle part so that said duckbills meet in engaging relationship, d. integral flexible hinge means in said second frame member to provide angular rotation of said upper duckbill with respect to said second frame member.

Claim 13

The invention as recited in claim 10 wherein a. one of said hollow handle part and said adjusting section defines a series of apertures therein, b. a lock projection on the other of said handle part and said adjusting section, c. and biasing means to engage said lock projection with one of said apertures to lock the relative position of said frame members.

Claim 14

The invention as recited in claim 11 wherein said handle portion defines said apertures and said adjusting section defines said lock projection.

Claim 15

The invention as recited in claim 12 wherein a separate member in said adjusting section is provided with said lock projection, and fulcrum means in said adjusting section to support said separate member for oscillating motion.

Claim 16

The invention as recited in claim 12 wherein said biasing means defines a notch portion in one of said members so that a part of said member can be flexed about said notched portion.

Claim 17

A vaginal speculum comprising in combination a. a first synthetic resin frame member defining a U section and an elongated handle section depending therefrom, b. a second synthetic resin frame member defining a U section and an elongated adjusting section depending therefrom, c. said sections being adapted to be telescopically interfitted in sliding register relationship, d. lower duckbill means extending angularly from said first frame member, e. upper duckbill means extending angularly from said second frame member, f. a thumb lock depressent means on said second frame member for disengaging lock projection means between said frame members for relative sliding relationship thereof, g. integral hinge means comprising oppositely disposed notched portions in the U section of said second frame member to permit dual angular adjustment of said upper duckbill, h. lever eans extending from said upper duckbill, and i. lock means extending from said U section of said second frame member to adjustably interlock with said lever to adjust the upper duckbill in angular relationship with respect to said lower duckbill.

Claim 18

A vaginal speculum comprising in combination a. a first synthetic resin frame member defining a U section and an elongated handle section depending therefrom, b. a second synthetic resin frame member defining a U section and an elongated adjusting section depending therefrom, c. said sections being adapted to be telescopically interfitted in sliding register relationship, d. lower duckbill means extending angularly from said first frame member, e. upper duckbill means extending angularly from said second frame member, f. a thumb lock depressent means on said second frame member for disengaging lock projection means between said frame members for relative sliding relationship thereof, g. integral hinge means comprising oppositely disposed notched portions in the U section of said second frame member to permit dual angular adjustment of said upper duckbill, h. lever eans extending from said upper duckbill, and i. lock means extending from said U section of said second frame member to adjustably interlock with said lever to adjust the upper duckbill in angular relationship with respect to said lower duckbill.

Claim 19

The invention as recited in claim 10 wherein said second frame member comprises a. a yoke member having a pair of upstanding arms, b. said integral flexible hinge means comprising a flexible hinge section integral with an end of each of said arms, c. snap fastener means on the end of each of said flexible hinge sections, d. said upper duckbill part having snap fastener apertures therein into which said snap fastener means project to join said upper duckbill part to said yoke member, e. a separate lock member in said elongated adjusting section, f. fulcrum means in said elongated adjusting section to support said lock member for oscillating motion, g. and a lock projection on said lock member adapted to project into openings in a distal wall of said first frame member.

Claim 20

The invention as recited in claim 10 wherein a. a laterally projecting pin member projects from said elongated adjusting section, b. a laterally flexible flap member extends from said upper duckbill part, c. said flap member having a series of apertures therein, d. said integral flexible hinge means permitting said apertures to be aligned with said pin member so that said flap member can be laterally flexed and said pin member caused to enter one of said apertures thereby locking said upper duckbill part in angular relationship to said elongated adjusting section.
