Abstract
Abstract A press-fitted joint between a transom bar and the frame or sash bar of a window, door or the like is provided having a connecting piece with parallel hooked ribs which enter the transom bar, such hooked ribs being in engagement with facing hooked ribs on the frame or sash bar wherein the engagement is effected solely with hooks of the connecting piece open in the same direction and hooks of the frame or sash bar open in the other direction and the inter-engaging hooked ribs permit of displacement of the connecting piece in relation to the opening of its hooks at least to the extent of the depth of the hooks relative to the frame or sash bar and that for securing the connecting piece in its frame or sash bar engaging position, one or more fixing pins are provided which are forced into registering holes of the connecting piece and the sash bar.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
338 words
A press-fitted joint between a transom bar and a frame bar for windows, doors and the like, wherein: a. the frame bar comprises an opposed pair of parallel side faces and at least one transverse web connecting said side faces, said web having on one side thereof at least two upstanding ribs running in the length direction of the frame bar in spaced parallel relationship with one another, each rib having a hook formed on its longitudinal edge which opens in a direction toward a given one of said pair of side faces of the frame bar; b. the transom bar comprises an opposed pair of parallel side faces and a spaced parallel pair of transverse webs connecting these side faces, said pair of webs defining a chamber therebetween; and, c. a connecting piece is disposed within said chamber and is removably secured to said transom bar, said connecting piece having a ribbed side proximate said one side of said web of the frame bar and provided with at least two elongated upstanding ribs running in the length direction of the frame bar in spaced parallel relationship with one another, each rib of the connecting piece having a hook formed on its longitudinal edge which opens in a direction opposite to that of said hooks of the frame bar and which interengages with a respective one of the latter hooks, the arrangement of said ribs of the frame bar and connecting piece being such that before the connecting bar and the frame bar are secured to one another the connecting piece is laterally displaceable relative to the frame bar in the open direction of said hooks of the frame bar at least to an extent which frees the respective intergaged hooks from interengagement, the connecting piece having parallel through holes therein which register with through holes in the web of said frame bar, the registering holes having fixing pins forced therein to secure the connecting piece and the frame bar to one another in their hook engaging position.
Claim 2
Dependent Claim
338 words
A press-fitted joint between a transom bar and a frame bar for windows, doors and the like, wherein: a. the frame bar comprises an opposed pair of parallel side faces and at least one transverse web connecting said side faces, said web having on one side thereof at least two upstanding ribs running in the length direction of the frame bar in spaced parallel relationship with one another, each rib having a hook formed on its longitudinal edge which opens in a direction toward a given one of said pair of side faces of the frame bar; b. the transom bar comprises an opposed pair of parallel side faces and a spaced parallel pair of transverse webs connecting these side faces, said pair of webs defining a chamber therebetween; and, c. a connecting piece is disposed within said chamber and is removably secured to said transom bar, said connecting piece having a ribbed side proximate said one side of said web of the frame bar and provided with at least two elongated upstanding ribs running in the length direction of the frame bar in spaced parallel relationship with one another, each rib of the connecting piece having a hook formed on its longitudinal edge which opens in a direction opposite to that of said hooks of the frame bar and which interengages with a respective one of the latter hooks, the arrangement of said ribs of the frame bar and connecting piece being such that before the connecting bar and the frame bar are secured to one another the connecting piece is laterally displaceable relative to the frame bar in the open direction of said hooks of the frame bar at least to an extent which frees the respective intergaged hooks from interengagement, the connecting piece having parallel through holes therein which register with through holes in the web of said frame bar, the registering holes having fixing pins forced therein to secure the connecting piece and the frame bar to one another in their hook engaging position.
Claim 3
Dependent Claim
53 words
A press-fitted joint according to claim 1, wherein the connecting piece has a compression screw arranged parallel to and between the fixing pins, said screw being forced against said one side of the transverse web of the frame bar so as to force abutting surfaces of the interengaged hooks tiGhtly against one another.
Claim 4
Dependent Claim
89 words
A press-fitted joint according to claim 1, wherein the other one of said pair of side faces of the frame bar is in abutting coplanar relationship with a recessed one of said side faces of the transom bar, the connecting piece extending from its ribbed side to an opposing flat side thereof in the longitudinal direction of the transom bar no further than said other one of said pair of side faces of the frame bar, the fixing pins not projecting beyond said flat side of the connecting piece.
Claim 5
Dependent Claim
53 words
A press-fitted joint according to claim 3, wherein said recessed side face of the transom bar is recessed by an amount permitting lateral access for said connecting piece to and from said chamber of the transom bar while said connecting piece is secured to the frame bar and unsecured to the transom bar.
