Abstract
Abstract A speculum for examining body cavities comprises two angle pieces, each having a generally U-shaped cross-section along substantially its whole length, and consequently troughed-like legs, both angle pieces with their troughs facing each other being removably connectable to each other with side portions thereof on either side of the speculum overlapping each other to form a pivot portion from which the four legs extend, respective legs of the angle pieces being movable together or apart by means of one pair of legs comprised of a leg of each angle piece, serving as handles for operating the other pair, and characterized in that both angle pieces are identically alike and that in the area of the pivot portion, each has on one side a pin and on the opposite side a hole, the hole in each angle piece being made to accommodate the pin of the opposing angle piece.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
189 words
A speculum arranged for examining body cavities and consisting of two angle pieces (1) each having a generally U-shaped cross-section along substantially the whole of its length, and consequently having trough-like legs (3, 4) of which one leg (3) is preferably narrower than the other (4), both angle pieces (1) with their troughs facing each other being removably connectable to each other with side portions of the angle pieces on either side of the speculum overlapping each other to form a pivot portion (2), from which the four legs (3, 4) extend, being movable together or apart by means of one pair of legs (3, 4), one from each angle piece (1), serving as handles for operating the other pair (4, 3), characterized in that both angle pieces (1) are made identically alike and that in the area of the pivot portion (2) each has on one side a pin (5) and on the opposite side a hole (6), the hole in each angle piece (1) being made to accommodate the pin (5) of the opposing angle piece (1) for creating the pivoting function of the pivot portion (2).
Claim 2
Dependent Claim
189 words
A speculum arranged for examining body cavities and consisting of two angle pieces (1) each having a generally U-shaped cross-section along substantially the whole of its length, and consequently having trough-like legs (3, 4) of which one leg (3) is preferably narrower than the other (4), both angle pieces (1) with their troughs facing each other being removably connectable to each other with side portions of the angle pieces on either side of the speculum overlapping each other to form a pivot portion (2), from which the four legs (3, 4) extend, being movable together or apart by means of one pair of legs (3, 4), one from each angle piece (1), serving as handles for operating the other pair (4, 3), characterized in that both angle pieces (1) are made identically alike and that in the area of the pivot portion (2) each has on one side a pin (5) and on the opposite side a hole (6), the hole in each angle piece (1) being made to accommodate the pin (5) of the opposing angle piece (1) for creating the pivoting function of the pivot portion (2).
Claim 3
Dependent Claim
79 words
A speculum as claimed in claim 1, characterized in that the pin (5) on either angle piece (1) is arranged on the outside of the said one side portion thereof and is made with a head, and that the hole (6) which is arranged in the other side portion (8) thereof merges into a radially outwardly directed slit (7) breaking through the edge of said other side portion (8) for inserting the pin of the opposing angle piece (1).
Claim 4
Dependent Claim
33 words
A speculum as claimed in claim 2, characterized in that the slit (7) is somewhat underdimensioned in relation to the pin (5) so that the pin is retained snapped in the hole (6).
Claim 5
Dependent Claim
65 words
A speculum as claimed in claim 2, characterized in that the width of the pin (5), transverse to the insertion direction in the slit (7) at a predetermined insertion orientation is narrower than the width of the pin in the insertion direction so that after mutual turning of the angle pieces (1) the pin is prevented from leaving the hole (6) via the slit (7).
Claim 6
Dependent Claim
52 words
A speculum as claimed in claim 2, characterized in that the pin (5) tapers from its base to its head, its base dimension being such as to conform with a tight fit to the diameter of the hole (6), or the least diameter thereof in the case where the hole dilates outwardly.
Claim 7
Dependent Claim
78 words
A speculum as claimed in claim 2, characterized in that the side portion (8) provided with hole (6) of both coupled side portions (1) overlaps on either side of the speculum the side portion of the angle pieces provided with the pin (5), the side portion (8) provided with the hole on each angle piece being made displaced sideways such that both the co-acting leg pairs (3, 3; 4, 4) of the angle pieces are mutually centred sideways.
Claim 8
Dependent Claim
137 words
A speculum as claimed in claim 2, in the case where the side portions (8) provided with the holes (6) have locking teeth (9) for fixing the angular position of the angle pieces (1) in co-action with leg projections (10) on the opposing angle piece, characterized in that a part of the respective side portion (8) provided with said hole (6) is made as a flap (12) by means of a pair of slits disposed on either side of the hole (6), the flap preferably provided with a folding line (14) at its base so that the remainder of the side portion (8) with the locking teeth (9) can remain substantially unaffected by axial compression of the pivot portion (2) via the flaps (12) for releasing the leg projections (10) from engagement with the locking teeth (9).
Claim 9
Dependent Claim
58 words
A speculum as claimed in claim 7, characterized in that a folding line (11) is arranged on the side portion of the angle piece behind the pin (5) so that when the pivot portion (2) is axially compressed the leg projection (10) is given a definite inward movement to release it from engagement with the locking teeth (9).
