Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A window having a tilting and swinging leaf, comprising a window casing, connection devices mounting the leaf on the window casing for horizontal movement of the leaf in the plane of the window casing from a first closed position to a second tilting position in which the leaf can be opened by a bellows-type motion and to a third swinging position in which the leaf can be opened as a casement window, and a control device comprising one rotatable operating handle mounted on the leaf and a horizontally sliding bolt detachably secured to the window casing and operable by rotation of said rotatable handle to move said leaf from any one of said positions to any other of said positions.
Claim 2
Dependent Claim
120 words
A window having a tilting and swinging leaf, comprising a window casing, connection devices mounting the leaf on the window casing for horizontal movement of the leaf in the plane of the window casing from a first closed position to a second tilting position in which the leaf can be opened by a bellows-type motion and to a third swinging position in which the leaf can be opened as a casement window, and a control device comprising one rotatable operating handle mounted on the leaf and a horizontally sliding bolt detachably secured to the window casing and operable by rotation of said rotatable handle to move said leaf from any one of said positions to any other of said positions.
Claim 3
Dependent Claim
17 words
A window according to claim 1, wherein the leaf is constituted by a pane of toughened glass.
Claim 4
Dependent Claim
20 words
A window according to claim 1, wherein said tilting position is located between the closed position and said swinging position.
Claim 5
Dependent Claim
93 words
A window according to claim 1, said connection devices comprising a bottom corner fitting located in the vicinity of the bottom edge of the leaf on the side of the window casing around which the leaf pivots when it is opened in said swinging position, said fitting having a horizontal supporting rod adapted to pivot around a vertical axis and on which the leaf is slidably mounted, and positioning means for maintaining the leaf in at least two locations with respect to the supporting rod corresponding respectively to said tilting and swinging positions.
Claim 6
Dependent Claim
46 words
A window according to claim 4, wherein the bottom corner fitting comprises a sleeve which is rigidly fixed to the bottom edge of the leaf and slidably mounted along the supporting rod, said sleeve being also capable of pivoting through a predetermined angle about said rod.
Claim 7
Dependent Claim
42 words
A window according to claim 5, wherein the leaf-positioning means comprise spaced notches formed along the supporting rod and corresponding respectively to said tilting and swinging positions, the sleeve being fitted with rolling elements which are capable of penetrating into said notches.
Claim 8
Dependent Claim
44 words
A window according to claim 6, wherein at least those notches which correspond to said tilting position are shaped so as to permit the transverse displacement of the rolling elements of the sleeve when said sleeve pivots about the supporting rod in said position.
Claim 9
Dependent Claim
59 words
A window according to claim 7, wherein the supporting rod is provided with a stop for the sleeve in order to prevent said sleeve from passing substantially beyond said swinging position, the position of said stop being such that the leaf which has come into abutment tends to be restored to said swinging position under the action of gravity.
Claim 10
Dependent Claim
52 words
A window according to claim 5, wherein abutment means are provided for the sleeve on the supporting rod in order to prevent the leaf which is assumed to be in said swinging position from being pushed into said tilting position when pivotal motion of the leaf about its vertical axis has begun.
Claim 11
Dependent Claim
59 words
A window according to claim 9, wherein the abutment means comprise a retractable lug which is restored elastically to the projecting position with respect to the supporting rod and serves as a stop for the sliding sleeve and a cam which controls the withdrawal of the lug when the plane of the leaf is parallel to the fixed window-casing.
Claim 12
Dependent Claim
58 words
A window according to claim 6, wherein an abutment means is provided for the sleeve in a ring which carries the supporting rod in order to prevent the leaf which is assumed to be in said tilting position from being displaced along said supporting rod when the pivotal motion of the leaf about its horizontal axis has begun.
