Abstract

The present invention relates to a handle 10 having a joint 20 suitable for connection to a trolley 1 with a central stem 2, the joint 20 having a handle 10 relative to the stem 2. Connect the handle to the center stem (2) so that can rotate.

Description

Handle {HANDLE}

The invention relates to a strong and comfortable handle, for example mounted on a trolley. The handle can be rotated to suit the person using the handle.

Trolleys for infants and children are already known, having a U-shaped handle in which the outer U-part of the handle can be adjusted in height through upward or downward movement and can be locked in some position. Adjustment is made by hingely connecting each end of the U-part to the main frame on each side of the trolley, the hinge comprising a locking device.

The problem with this solution is that in order to release all of the locking devices, the user has to stop walking, in turn, change the angle, and then lock all of the devices again before continuing to walk. In practice, the angle only changes when another user needs it or when the trolley has to be folded to fit the reservoir, for example.

The purpose of the height adjustment of the handle is to make the trolley suitable for the pusher's height, but the prior art solution also affects the distance between the user and the trolley itself. The problem when the handle is in a nearly vertical upward position, adapted for tall people, is that long legs cannot walk properly without the feet touching the wheels or frame of the trolley.

It also means that the angle of force applied when pushing the trolley is not optimized because it changes with the height of the handle.

Moreover, these handles cannot be used on trolleys with a frame comprising a central main stem as described in WO 03/035448.

The handle according to the present invention is symmetrically with a joint that allows the handle to rotate in the plane of the object to which the handle is attached, such as the frame of the trolley, or more preferably the center main stem of the trolley with telescopic extension. A formed handle.

As shown in FIG. 1, the handle 10 according to the present invention is suitable as a handle for a trolley 1 with a central stem 2. The trolley 1 has a center stem 2, and a handle 10 is mounted on the upper end of the center stem 2.

The handle 10 can be rotated at different angles relative to the frame and is connected to the central stem 2 by a joint 20. The joint 20 can rotate the handle, for example to the lever 21 (see FIG. 5) at different predetermined positions as shown in FIGS. 2 to 4 and respectively seen at different angles in FIGS. 5 to 7. The handle can be locked and unlocked.

In this embodiment, the joint 20 comprises a cylinder part 22 of the handle 10, which extends through a casing 24 as shown in FIG. 8, in which the cylinder is to be rotated by an axis of rotation. Can be. This allows, for example, the handle 10 to be rotated nearly 360 ° through the plane of symmetry of the frame of the trolley.

The cylinder part 22 may comprise a recess 23, in which the locking pin 25 is loaded, for example by means of a lever 21, preferably with a spring to lock the handle 10 in place. Can be introduced.

This solution enables a number of different height positions of the handle 10. Similarly, this solution allows the handle 10 to be adapted to the angle at which the user's force is applied to the object to which the handle is attached. Thus, in combination with the telescopic stem as described in WO 03/035448, the handle can be adjusted to both the exact height and the angle at the same time.

In this embodiment, the handle 10 has an elliptical or D-shaped transverse piece fastened to the joint 20 at the symmetrical middle of one of its main arches. In another embodiment, the handle can have an opening or cutout in the symmetrically opposite midpoint of the joint, such that the handle 10 can rotate freely over 360 ° relative to the trolley.

Furthermore, this shape of the handle 10 does not change the angle of the handle, but two different height positions on the handle 10, or nearly horizontal positions (FIGS. 3 and 7) when in the vertical position (FIGS. 4 and 7). 6) allows the user access to two different distances from the frame, or a combination thereof (Figures 2 and 5) depending on where the handle is locked.

The handle may, for example, be made of plastic, aluminum or steel and may have a coating and insulation that provides excellent grip on the handle face. Various modifications are possible in the design of the handle.

According to the configuration of the present invention, the handle 10 may have a number of different height positions. In addition, the handle 10 may be adapted to an angle at which the user's force is applied to the object to which the handle is attached. Thus, in combination with the telescopic stem, the handle can be adjusted to both the exact height and the angle at the same time.
