Definitions
- This invention relates to a motor-driven trolley which is intend ⁇ ed to be connected to a wheel-mounted loading trolley in order to drive the latter.
- EP-B1-0 281 536 discloses a laundry trolley for use at hotels, hospitals and the like.
- This trolley is designed for use as a cleaning trolley, one or more removable sections for the cleaning articles being then applied to the trolley.
- the section or sections are preferably equipped with wheels, as is the trolley itself (in the following referred to as the loading trolley).
- the use of such section-equipped loading trolleys has created a need for facilitating their displacement.
- a section is provided with a motor which is so arranged, according to one aspect of the invention, that the section (in the following referred to as the motor-driven trolley) is easily and expediently connectible to the load- ing trolley and that the assembly consisting of the loading trolley and the motor-driven trolley is easily driven with the aid of the motor- driven trolley.
- the motor-driven trolley should itself be movable by motor operation and that it should be possible to wheel by hand not only the motor-driven trolley but also the assembly consisting of the loading trolley and the motor-driven trolley.
- Figs 1A and B and 2A and B illustrate the inventive concept
- Fig. 3 shows an arrangement for moving the driving wheel of the motor-driven trolley between two stable positions.
- Figs 1A and B and 2A and B which illustrate the inventive con ⁇ cept, show an undriven loading trolley A having four castor wheels 1 , as well as an inventive motor-driven trolley B having two fixed wheels 2 and two castor wheels 2a.
- the motor-driven trolley B has a battery- powered motor 3 and a wheel 4 fixed to the output shaft thereof.
- the motor-driven trolley B can be mechanically connected to the loading trolley A in order to drive the latter.
- the wheel 4 with the associated motor 3 is vertically displaceable in the motor-driven trolley B, such that it can be brought into engagement with the floor C, which enables the motor-driven trolley B and the loading trolley A connect ⁇ ed thereto to be driven on the floor C (Fig. IB), in which case the wheels 2, 2a of the motor-driven trolley have no floor contact.
- the motor-driven trolley B and the loading trolley A optionally connected thereto can be wheeled by hand on the floor C on the wheels 1, 2a, 2 (Figs 1A and 2B), or preferably on the wheels 1 only when interconnected, which makes it easier to cross thresholds because the trolley B is hanging freely on the loading trol ⁇ ley A, in which case e.g.
- the wheels 2, 2a may have a suspension of shorter length than the one shown in the Figures.
- the wheel 4 is arranged behind the wheels 2, 2a at the back of the motor trolley B.
- the castor wheels 2a can thus have floor contact, so that the motor-driven trolley B can be driven separately (Fig. 2A).
- the motor-driven trolley B is provided with hooks 5, 6, and the trol ⁇ ley A is provided with pockets or rods 7, 8.
- the hook 5 is articulated and preferably spring-loaded, such that the hook 6 is first brought into engagement with a pocket or rod 7 (after tilting the motor-driven trolley B clockwise, as seen in Figs 1 and 2), and the hook 5 is then brought into engagement with a pocket or rod 8.
- EP-B1-0 281 536 describes such an interconnection arrangement, as well as other such arrangements that might be used.
- the vertical displacement of the wheel 4 and the associated motor 3 is brought about with the aid of a tube 9 fixedly connected to the wheel 4 and the motor 3, an operating handle 10 and a dead- centre elbow mechanism 11 (see Fig. 3) interconnecting the tube 9 and the handle 10.
- the operating handle 10 is articulated to the tube 9 at 12 and to a tube 14 by means of a link 15.
- the tube 14 which is fixedly connected to the chassis 13 (which carries the wheels 2, 2a) of the motor-driven trolley, the tube 9 can be vertically displaced as well as rotated about its longitudinal axis.
- the elbow mechanism 11 passes from a position in which the handle 10 is vertical (dash-dot line 10'; the centre axis) to a position in which the handle 10 has been turned through 90° (dash-dot line 10") in which the wheels 2, 2a have been moved out of previous floor contact, if any, a dead-centre position having been passed, as indi ⁇ cated by the dash-dot link 15.
- the stroke length of the tube 9 can be suitably set by having the point of articulation 16 of the link 15 on the tube 14 arranged on a stop bushing 17, which is vertically displaceable on the tube 14 and can be fixed in the set vertical position and which further can rotate round the tube 14 to enable rotation of the wheel 4, such that the trolley A can be moved in different directions.
- An electric wire 18 running through the tube 9 connects electric control means 19 provided on the handle 10 with the motor 3 via con ⁇ trol electronics 20 for the motor 3.
- the control electronics 20 may, inter alia, be adapted to adjust the speed and reverse the motor 3.

Abstract
On décrit un chariot (B) adapté pour être relié à un chariot récepteur à roues (A). Ce chariot (B) est équipé de roues intermédiaires (2, 2a) permettant de le déplacer manuellement, seul ou associé au chariot récepteur (A). Ce chariot (B) possède de plus une roue entrainée par moteur (4). La roue (4) et son moteur associé (3) sont fixés sur un tube (9) pouvant se déplacer verticalement et en rotation dans le chassis (13) du chariot (B). On peut modifier la position du tube (9) par rapport au chassis (13) à l'aide d'une poignée de commande (10). La poignée de commande (10) est articulée par rapport au tube (9) et au chassis (13), grâce à un dispositif de centrage coudé (11). Dans l'une des positions stables du dispositif coudé (11), la roue entraînée par moteur (4) vient en contact avec le sol de façon à entraîner le chariot (B) et le chariot récepteur (A) si celui-ci est relié. Dans l'autre position stable du dispositif coudé (11), seules les roues intermédiaires (2, 2a) du chariot (B) reposent sur le sol, le chariot (B) est relié au chariot récepteur (A).
