Abstract

Rotary joint for a parasol of a stroller, comprising a fastening part (1) which has two round recesses (11) which each form a toothing (12) on the inner wall, and two joints (2) which are articulated with the fastening part (1) are connected and each have a projection (21) which is inserted into the recess (11) and forms a plurality of grooves (23), in each of which a leaf spring (24) is arranged, which the groove (23) in a front Chamber (231) and a rear chamber (232) divides, a locking element (25) for the toothing (12) being arranged in the front chamber (231).

Description

The invention relates to a hinge for a parasol of a stroller, in particular a hinge, which can reduce wear and extend the life.

7 shows a conventional swivel for a parasol of a stroller, which comprises a fastening part (B) and joints (C). The fastening part (B) has teeth (B1). The joints (C) have locking elements (C1), which engage in the teeth (B1), whereby a rotational positioning is made possible. When turning the joints (C), the limiting elements (C1) and the teeth (B1) may wear due to the friction. After a longer period of operation, the fastening part (B) and the joints (C) lose the positioning function, so that the parasol when unfolding and folding can not be positioned.

The invention has for its object to provide a hinge for a parasol of a stroller, having damping elements that can reduce the wear during rotation, so that the life of the rotary joint is extended.

This object is achieved by the inventive swivel for a parasol of a stroller, comprising: a fastening part having two round recesses, which each form a toothing on the inner wall, and two joints, which are hingedly connected to the fastening part and each have a projection which is inserted into the recess and forms a plurality of grooves, in each of which a leaf spring is arranged, which divides the groove into a front chamber and a rear chamber, wherein in the front chamber, a locking element for the toothing is arranged.

The projections of the joints each have three grooves which enclose an angle of 120 ° with each other.

The attachment part is attached to the stroller and the joints are attached to the parasol of the stroller.

The boundary elements engage in the toothing and form at the end facing the toothing in each case an inclined surface.

• 1. Verlängerung der Lebensdauer des Drehgelenks,
• 2. Erhöhung der Stabilität beim Aufklappen und Zusammenklappen des Sonnenschirms des Kinderwagens.

Therefore, the invention has the following advantages:

• 1. extension of the life of the swivel joint,
• 2. Increasing the stability when unfolding and folding the parasol of the stroller.

In the following the invention with reference to embodiments with reference to the drawings will be described in detail. In the drawing shows:

1 an exploded view of a preferred embodiment of the invention,

2 a representation of the preferred embodiment of the invention with the stroller,

3 a sectional view of the movement of the preferred embodiment of the invention ( 1 )

4 a sectional view of the movement of the preferred embodiment of the invention ( 2 )

5 a sectional view of the movement of the preferred embodiment of the invention ( 3 )

6 an exploded view of another embodiment of the invention and

7 a representation of the conventional solution.

The 1 and 2 show a preferred embodiment of the invention, which comprises:
a fastening part ( 1 ), which is attached to the stroller (A) and two round recesses ( 11 ), which on the inner wall in each case a toothing ( 12 ), and an opening ( 13 ), which with the two recesses ( 11 ) and in the center of the two recesses ( 11 ), and
two joints ( 2 ), which can be folded up and down with the sunshade (A1) and the fastening part (A1). 1 ), the joints ( 2 ) each have a projection ( 21 ), which in the recess ( 11 ) is inserted and in the middle of a through hole ( 22 ) for the opening ( 13 ), wherein a hinge pin ( 3 ) through the through holes ( 22 ) and the opening ( 13 ), whereby the joints ( 2 ) with the fastening part ( 1 ) are hinged, the projection ( 21 ) a plurality of grooves ( 23 ), in each of which a leaf spring ( 24 ) is arranged, which the groove ( 23 ) in a front chamber ( 231 ) and a rear chamber ( 232 ), whereas in the anterior chamber ( 231 ) a blocking element ( 25 ), the rear chamber ( 231 ) as a damping chamber of the blocking element ( 25 ), wherein the blocking element ( 25 ) out of the lead ( 21 ) and into the gearing ( 12 ), wherein the blocking element ( 25 ) at the end facing the toothing an inclined surface ( 251 ), through which the joint ( 2 ) slightly into the recess ( 11 ) of the fastening part ( 1 ), and whereby by the rotational positioning of the joints ( 2 ), the opening angle of the sunshade (A1) can be controlled.

Like from the 3 . 4 and 5 it can be seen that the joints ( 2 ) when folding or folding the parasol (A1) of the stroller (A) moves, wherein the limiting elements ( 25 ) of the toothings ( 12 ) against the leaf springs ( 24 ), which are thus in the rear chambers ( 232 ) so that the boundary elements ( 25 ) are pushed inwards. This allows the joints ( 2 ) to be turned around. When the umbrella is stationary, the boundary elements ( 25 ) of the leaf springs ( 24 ) and put back into the gears ( 12 ), so that the parasol (A1) of the stroller (A) is positioned.

In 6 have the projections ( 21A ) of the joints ( 2A ) each have three grooves ( 23A ), which enclose an angle of 120 ° with each other, whereby the joints ( 2A ) better with respect to the fastening part ( 1 ) can be positioned.

The foregoing description represents only the preferred embodiments of the invention and is not intended to serve as a definition of the limits and scope of the invention. All equivalent changes and modifications are within the scope of this invention.
