Abstract
Abstract The invention refers to some improvements in the foldable frames for children's pushchairs, of the type which includes the handlebar fitted slidingly over the front legs, with the folding of the pushchair being obtained with the bringing down of the handlebar. With these improvements, a very complete, light children's pushchair with a simple structure and very compact folding up is obtained. These advantages are achieved by structuring the frame on the basis of a linked triangulation formed on each side by the rear (3) and front (1) legs, and by a base frame (5), the rear leg (3) being linked by its upper end (9) on a solidly jointed flange (7) of the lower end of the brace members of the handlebar (6) and along which it slides guided by the front leg (1), the front (1) and rear (3) legs being related to each other by means of the base frame (5) and the front legs (1) being finished off at the top with a guiding flange (8) along which the corresponding brace member of the handlebar (6) slides.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
- Improvements in the foldable frames for children's pushchairs, of the type which includes the handlebar fitted slidingly over the front legs, with the folding of the pushchair being obtained with the bringing down of the handlebar, characterized essentially by the fact that the lower end of the brace members of the handlebar (6) includes a guiding flange (7) solidly jointed on the front leg (1), on whose flange (7) the upper end (9) of the corresponding rear leg (3) is linked, which is eye-jointed with the front leg (1) with a base frame (5) which also links the legs of each side together, with the mentioned guiding flange (7) including the linkage of a brace (10) which supports the seat frame (12) by linkage through the centre of its sides, which link through their rear part at an intermediate point (13) of the rear legs (3).
Claim 2
Dependent Claim
147 words
- Improvements in the foldable frames for children's pushchairs, of the type which includes the handlebar fitted slidingly over the front legs, with the folding of the pushchair being obtained with the bringing down of the handlebar, characterized essentially by the fact that the lower end of the brace members of the handlebar (6) includes a guiding flange (7) solidly jointed on the front leg (1), on whose flange (7) the upper end (9) of the corresponding rear leg (3) is linked, which is eye-jointed with the front leg (1) with a base frame (5) which also links the legs of each side together, with the mentioned guiding flange (7) including the linkage of a brace (10) which supports the seat frame (12) by linkage through the centre of its sides, which link through their rear part at an intermediate point (13) of the rear legs (3).
Claim 3
Dependent Claim
106 words
- Improvements in the foldable frames for children's pushchairs, in accordance with claim 1, characterized by the fact that the lower end of the brace members of the handlebar (6) is provided with a safety catch (30) stressed elastically which attaches at two solidly jointed pivots (31) of the upper zone of the front legs (1) where there are handlebar ascent stopping dogs, whose safety catches (30) are unlocked by manual action on corresponding elastically stressed levers (32) linked on two solidly jointed flanges (8) of the upper end of the front legs (1) along whose flanges (8) the brace members of the handlebar (6) slide.
Claim 4
Dependent Claim
193 words
- Improvements in the foldable frames for children's pushchairs, in accordance with claim 1, characterized by the fact that, instead of the linked seat frame (12), a support (35) is freely inserted in the brace members of the handlebar (6), above the guiding flanges (7), and it supports the seat frame (36) in a slanting manner, whose support (35) includes: a main central block (37) provided transversally with a passage (38) for the mentioned inserting, a slight rear cavity (39) with internal stopping dog (40) and with its toothed periphery (41) and on its front side a central tubular rod (42) with opposite planes (43); a secondary inserted block (44) fixed on the frame (36) of the seat and which is provided with a cavity (45) with stopping dog (46) and annullar toothing (47) on its front side; and a control knob (48) formed by a housing which is transversally provided with an opening (49) for the passage and fitting of a safety catch (50) with a spring (51) which in its centre is provided with a keyhole-shaped orifice (52), which is inserted in the tubular rod (42) of the main block (37).
Claim 5
Dependent Claim
118 words
- Improvements in the foldable frames for children's pushchairs, in accordance with claim 3, characterized by the fact that the control knob (48) is, on its inside, provided with a transversal housing (53) where the safety catch (50) is housed, and includes on each side of the housing some extensions (54) on which some convex protrusions (55) of the front side of the central block (37) are supported in the position for locking the support (35) of the seat, while on pressing the safety catch (50) and turning the knob (48) on an angle, the mentioned convex protrusions (55) fit in the mentioned transversal housing (53), unlocking the support (35) so that the seat position can be changed.
Claim 6
Dependent Claim
66 words
- Improvements in the foldable frames for children's pushchairs, in accordance with claims 3 and 4, characterized by the fact that the secondary knob (44) and the control knob (48) are related to each other and are attached with a shaft (57) which crosses the main block (37) on whose shaft (57) a spring (56) arranged between the main (37) and secondary (44) blocks is inserted.
Claim 7
Dependent Claim
68 words
- Improvements in the foldable frames for children's pushchairs, in accordance with claim 1, characterized by the fact that the front legs (1) are provided with an elastically stressed (61) coupling lever (60) in their upper zone, by means of which the unfolded position of the pushchair is locked upon latching on the lever a hook (62) envisaged in the guiding flanges (7) making up the handlebar (6).
