Detailed Description υf the Invention
In this detailed description, the preferred embodiments of the inventive shopping trolley are described only to facilitate belter understanding of the invention without producing any limiting effect.
In terms of the elements of the prior art, the invention comprises a supporting body (10), a handle (40) provided on the said supporting body (10), a chassis (20) and wheels (30) that enable the movement of this structure.
The present invention comprises a lifting mechanism (60) having amoveable surface (61 ) which enables the products placed in the basket ( 12) of lhe supporting body ( 10) to be lifted upwards and which is positioned on the base sides (11) of the supporting body (10); motion transfer rods (62), which enable upward and downward movement of the said movcable surface (61), and which are connected to the said surface (61 ); and a spring (65) and a movcable collar (64) that enable these rods (62) to be drivca
The invention comprises hinge points (63) which enable movement of the motion transfer rods (62) connected to the movcable surface (61 ), a fixed bearing shaft (67) which guides upward and downward movement of the said moveable collar (64) and which is also connected to the chassis (20), a pedal (66) which is positioned below the said moveable collar (64) and which is able Io move axially for the spring (65) that is in compressed state to be able to apply pressure, a pedal slot (68) formed on the bearing shaft (67) in order for the movcable surface (61) to be brought to normal position and for the pedal (66) to be locked, at least one locking mechanism (50) which is formed on the said supporting body (10) and which enables operation of the said lifting mechanism (60).
Operation of the mechanism is as follows: when the products placed on the moveable surface (61) are desired to be lifted upwards together with the movcable
surface (61), the pedal (66) which is affixed in the pedal slot (68) (see Figure 4) is moved axially in the s-direction by Toot whereby it is released from the pedal slot (68) (see Figure 3). With the axial movement of the pedal (67), the compressed spring (65) gels released and pushes the movcablc collar (64) upwards in the a- direction. With the movement of the moveable collar (64) in the aκJirection, the motion transfer rods (62) connected to the collar (64) also move.
Since the motion transfer rods (62) are connected to the moveable surface (61) via the hinge points (63), they push the moveable surface (61) upwards in a-direction by means of the spring (65) and the moveable collar (64). The moveable collar (64) exerts the push movement on the bearing shaft (67). Since it is fixed on the said shaft (67), it moves linearly upwards and downwards.
In order to bring the moveable surface (61) to normal position, that is to lower it, again the pedal (66) is pressed by foot to be positioned into the slot (68). With this movement, while the collar (64) and the motion transfer rods (62) are moving downwards they also pull the moveable surface (61 ), to which they are connected, downwards whereby the process is completed. There are holders (61.1) positioned to ensure easy sliding of the moveable surface (61) Ln its upward and downward movement. The said holders (61 -1) are cylindrical and are produced from plastic or metal parts. Additionally barriers (61.2) are formed on the moveable surface (61). Since the weights of the goods on the moveable surface (61 ) are not equal, the surface is prevented by means of the barriers (61.2) from failure to ascend in case it slips to one side.
In Figure 5, as an example to an alternative configuration, it is possible Tor the moveable surface (61) to be moved automatically by depressing a button rather than being moved manually. Upon supplying drive to the motor, which is an actuator (69), the actuator (69) provides rotational movement to the bearing shaft (67). In this system, there are threaded surfaces formed on the bearing shaft (67). In the inner surface of the moveable collar (64), which corresponds to the
threaded outer surfaces (67.1) and which is fixed with this screw just like a screw & nut relation, there arc again threaded surfaces (64.1) formed. With the rotational movement of the bearing shaft (67) the tnoveable collar (64) moves upwards. With the said movement, the transfer rods (62) push the moveable surface (61) to which they arc connected ensuring upward movement thereof, In order for the threaded outer surface of the bearing shaft (67) to perform rotational movement, it is fixed onto the body (67.3) via a ball bearing (67.2). While the threaded part of the shaft (67) is performing rotational movement, the body (67.3) remains in fixed position. This is enabled by the ball bearing (67.2).
Scope of protection of the present application is specified in the claims. It can definitely not be limited to the above description which is provided by way of example. Tt is clear that a person skilled in the art can disclose the innovation disclosed in the present invention by using similar configurations and/or can apply this configuration to other areas of similar objectives used in the related art. Thus, it is obvious that the said configurations will lack novelty and particularly the criterion of surpassing the state of the art.
