Abstract

An adjustable handle 1 for pushchairs is articulated at the top of handlebar stem 7 about a pivot 4. The handle may be formed of two parts 2,3 the first of which 2 is rotatable about an axis F relative to the second part 3. The first part has a threaded shaft (8 fig 3) which engages with a rack 12 fixed to a ferrule 5 that is attached to the stem 7. Rotation of the handle about axis F causes the handle to alter the angle it makes with the stem 7. The handle may be rotationally fixed about pivot 4 by means of a cog wheel 25 engaging with a toothed inner rim 18 of a first part of the handle. The cog wheel is ordinarily rotationally fixed to a second part 3 of the handle by engaging with a toothed inner rim 24. The cog wheel may be released from engagement with rim 24 by pressing a spring 26 biassed button 27 and then rotating the handle to a new position where it can be locked.

Description

1 Adjustable handle for pushchairs 2331479 This invention concerns an

adjustable handle for pushchairs.

Such a handle is situated at the upper end of each of the stems comprising the handlebars of pushchairs, which are pushed by gripping said handles.

The object of this invention is to allow the position of this handle to be adjusted in a practical and efficient manner, permitting the pushchair to be pushed in the most comfortable and reasonable manner in accordance with each individual's grip, taking into account the varying height of the people that will have to push the pushchair.

This adjustment of the handle consists of its greater or lesser inclination in a single plane, the adjustment being made possible by the handle being transversally articulated at the upper end of each of the stems comprising the handlebars.

This handle is made up of two parts, one of which forms the grip and is coupled at its base, in such a manner as to allow it to rotate around its long axis, to the other part, which forms the articulated support situated at the upper end of each of the stems comprising the handlebars.

The grip is prolonged at its base in the form of a threaded shaft that meshes with a segmental rack extending from the upper end of each of the stems comprising the handlebars, in such a way that as the 2 grip is rotated, the handle changes position in a single plane, turning around a transverse articulation.

In order to ensure the stability of the position chosen for the handle, the joint connecting the grip and the support is provided with a projection and a recess, respectively, that fit together to stabilise the position selected.

In this invention, it has also been envisaged, that, of the two parts the handle is made of, the first part is on which the handle is gripped, whilst its rear zone is articulated by means of a transverse pivot to the second part, which will form a support attached to the top end of the stems comprising the handlebars.

This first part of the handle is in the form of a cup perforated at its centre and provided with teeth around its inner rim, and the top of the second part of the handle is in the form of two cups facing each other and separated by a divider that is perforated at its centre, with these two parts of the handle being joined by and articulated around the transverse pivot passing through their aforementioned perforations.

One of the cups forming the above mentioned second part of the handle f aces the cup at the base of the f irst part and is also provided with teeth around its inner rim. Between these two cups is a cog-wheel that can move along the aforementioned transverse pivot and is pushed by a spring against the divider separating the two cups forming the second part of the handle.

The cup f orming part of the second part of the handle and facing the cup forming part of the first 3 part incorporates a push-button that impinges on the aforementioned cog-wheel, pushing it against the bottom of the cup forming part of the aforementioned first part, compressing the aforementioned spring.

These and other characteristics are shown more clearly in the detailed description given below and to facilitate understanding of same two plates with drawings are attached, showing two practical models, which are given merely as an example, with no limitation of the scope of this invention. In the drawings:

Figure 1 shows a side view of the handle; Figure 2 shows a top view of the handle; and Figure 3 shows a cutaway side view of the handle.

Figure 4 shows a cutaway side view of the 20 articulation zone between the two parts of the handle, according to another model, and Figure 5 shows a side elevation view of the articulation between the two parts of the handle when separated. 25 As shown in the drawings Nos. 1 to 3, the handle 1 is made up of two parts: the grip 2 and the base support 3, which is articulated around a transverse pivot 4 at the upper end 5 of a ferrule 6 extending from stem 7 of the handlebar.

4 The grip 2 is prolonged at its base in the form of a threaded shaft 8 (Figure 3) housed in the hollow support 3 and the grip 2 is coupled at its base, in such a manner as to allow it to rotate around its long axis F in the support 3, to which it is fastened by means of an end cap 9 abutting on the rear rim 10 of the pupport 3, attached by means of an axial screw 11 to the base end of the threaded shaft 8.

changing its inclination as the grip 2 is rotated around its long axis, i.e. around itself, and the threaded shaft 8 meshes with a segmental rack 12 extending from the upper end 5 of the ferrule attached to the stem of the handlebar. By rotating the grip in one direction, the is handle will increase A the angle that it forms with the stem of the handlebar, and by rotating the grip in the opposite direction, the handle will decrease Dthe angle that it forms with the stem of the handlebar, in the same plane.

In order to ensure the stability of the correct position chosen for the handle, the joint 13 connecting the grip 2 and the support 3 is provided with a projection 14 and a recess 15, respectively, (Figure 2) that fit together after each full turn F of the grip 2, this projection and recess separating and fitting together owing to the elastic nature of the plastic material from which the handle is made.

In accordance with figures 4 and 5 of the drawings, this handle for pushchairs is made up of two parts, the first part 2 forming the grip with its base The handle 2 turns on nivot 4 connected by means of a transverse pivot 41 to a divider 51 forming part of the second part 3 of the handle, which forms a support extending from a ferrule 6 f itting onto the top end of each of the stems 7 of 5 the handlebars of the pushchair.

The aforementioned first part 2 of the handle forms at its base a cup 16 with a perforation 17 through its centre and a toothed inner rim 18, and the second part 3 of the handle 19 and 20 facing each other S' with a perforation 21 at 2 and 3 being joined by transverse pivot 41 passing perforations 17 and 21 and forming two heads 22 and 23.

The cup 19 f orming part of the second part 3 of the handle faces the cup 16 of the first part 2 and also has a toothed inner rim 24. Between these two cups is placed a cog-wheel 25 held on pivot 41 and which is free to move along the length of that pivot and is pushed by helical spring 26 (placed between that cogwheel and the bottom of the cup 16) against the divider 51 of the second part 3 of the handle.

The cup 20 forming part of the aforementioned second part 3 incorporates a push-button 27 that impinges on the cog- wheel 25 by means of projections 28 around its rim that pass through the corresponding openings 29 in the divider 51, pushing the aforementioned cog-wheel against the bottom of the cup 16 and compressing the spring 26.

is forms at its top two cups and separated by a divider its centre, these two parts and articulated around a through the aforementioned held in place by its tips 6 Alternating with the projections 28 around the rim of the aforementioned push-button are a number of retaining teeth 30 that, when the spring 26 recovers its full length, press against a rim 31 of the opening of the cup 20.

The handle is adjusted to different positions in its vertical plane as follows: In figure 1, the 1 articulation is blocked and the handle is held firmly in a predetermined position. In this position of the handle, the cogs of the cog-wheel 25 mesh with the teeth 24 of the cup 19 and the teeth 18 of the cup 16.

In order to change the angle of the handle in its own vertical plane, the push-button 27 is pushed in direction F, which pushes the cog-wheel 25 and disengages it from the teeth 24 of the cup 19 and engages the aforementioned cog-wheel solely with the teeth 18 of the cup 16, with the result that the part 2 of the handle comprising the grip is free to rotate around the transverse pivot 4'. When the desired position of the handle is reached, the push-button 27 is released and the spring 26 recovers its full length and pushes the cog-wheel 25 back to its initial position against the divider 57, the articulation mechanism then being blocked once again, with the handle held firmly in the selected position.
