Description

The present invention relates to a trolley, in particular for storing and transporting objects such as tools and / or workpieces.

Dolly are used for example in super and hardware stores, where they are referred to as shopping carts. Depending on the design, the shopping carts have a wire basket, in which the objects that are to be purchased can be stored and transported to the cash register and possibly further to the motor vehicle.

While such shopping carts have been well-proven for smaller items, difficulties arise when the items are so long and / or wide that they overhang the wire basket. This is the case, for example, with flat objects such as wood panels or large beverage crates. For such items, trolleys are used in particular in hardware stores and beverage markets, which have no wire basket, but arranged near the bottom shelf on which the flat objects or beverage crates can be stored.

After use, such shopping carts and such trolleys can be pushed into each other and thus space-saving and relative to each other more or less position-defined parked. The ability of the dolly to be pushed into each other, is also referred to as a graduated ability.

Such dolly with arranged near the bottom shelves are also used in factories to transport, for example, to be processed or machined workpieces to processing machines or storage warehouses. The transport of tools is carried out with such transport vehicles. The disadvantage of this is that the sometimes heavy objects must be lifted by the employees of the near-bottom storage shelves and consequently from a small height and stored there, to which a high physical effort is necessary and health hazards and especially back problems can be caused. Known dolly, which have a working height arranged shelf, are not graduated and therefore can not be stored to save space. They are therefore placed in an arbitrary position in the workshop, creating a picture of disorder. Such dolly, sometimes referred to as a tool cart, are in the DE 80 32 425 , of the DE 201 19 610 U1 , of the DE 197 53 783 A1 and the DE 37 23 464 A1 disclosed.

Object of an embodiment of the present invention is to provide a trolley, in particular for storing and transporting objects such as tools and / or workpieces, which can be provided with simple and inexpensive means. In particular, the trolley should have a shelf, which can be arranged at a working height, the trolley should still be staggered and consequently save space.

This object is achieved with the features specified in claim 1. Advantageous embodiments are the subject of the dependent claims.

• - eine Trägereinrichtung, die eine Längsachse definiert, entlang welcher sich die Trägereinrichtung verjüngt,
• - wobei an der Trägereinrichtung drei oder mehr als drei Räder befestigt sind, oder
• - wobei an der Trägereinrichtung zwei Räder und zumindest ein Auflageabschnitt befestigt sind,
• - wobei die Räder bzw. die Räder und der Auflageabschnitt eine Bezugsebene definieren, und
• - zumindest eine an der Trägereinrichtung befestigte Trägersäule, an welcher eine Ablageplatte zwischen einer ersten Position, in welcher die Ablageplatte im Wesentlichen senkrecht zu der Bezugsebene, und einer zweiten Position, in welcher die Ablageplatte im Wesentlichen parallel zu der Bezugsebene verläuft, bewegbar befestigt ist.

An embodiment of the invention relates to a transport vehicle, in particular for storing and transporting objects such as tools and / or workpieces

• a support means defining a longitudinal axis along which the support means tapers,
• - Wherein three or more than three wheels are attached to the support means, or
• - Wherein two wheels and at least one support portion are attached to the support means,
• - Wherein the wheels or the wheels and the support portion define a reference plane, and
• at least one support column fixed to the support means, on which a support plate is movably mounted between a first position in which the support plate is substantially perpendicular to the reference plane and a second position in which the support plate is substantially parallel to the reference plane.

The reference plane is defined by the wheels or the wheels and the support section so that the reference plane is substantially parallel to the support on which the transport carriage is moved and parked. The longitudinal axis extends in the reference plane or parallel thereto.

The proposed transport vehicles are inserted into one another and consequently staggered. The scalability is achieved in that the support means tapers along the longitudinal axis and that the storage plate is movable between two positions. In the first position, the worktop is perpendicular to the reference plane and therefore takes virtually no space parallel to the reference plane. As a result, the trolley can be inserted very far into one another, so that many of the proposed trolley are parked particularly space-saving.

The attachment of the tray to the support column makes it possible to arrange the tray at least in the second position spaced from the support means. The distance can be chosen so that the shelf is located in the second position at working height. As a result, the objects to be transported can be stored back-friendly on the shelf and removed from her. In addition, the objects can also be processed directly on the trolley so that the trolley takes over the function of a mobile worktop. Such a processing is particularly suitable for wood or metal plates and wooden boards. The term support column is to be understood primarily to mean that it is designed as a rod-shaped and one-piece support. In addition, however, the support column may also comprise multi-part support elements which are rotatably secured together.

According to a further embodiment, the carrier device comprises a first side carrier and a second side carrier which extend in an angle lying in the reference plane to the longitudinal axis. As a side support common profiles can be used, so that the support means can be provided inexpensively. In addition, the profile can be chosen so that the forces and moments occurring can be safely absorbed without an increased space requirement. The course of the side support with respect to the longitudinal axis makes it possible in a simple manner to design the trolley staggerable.

In a further developed embodiment, the carrier device may have a first cross member, which runs perpendicular to the longitudinal axis and which connects the first side carrier and the second side carrier with each other. The first cross member increases the rigidity of the support without requiring much space.

In a further developed embodiment, the first side support and the second side support may each have a front end, wherein the first cross member interconnects the first side support and the second side support at their front ends. The arrangement of the first cross member at the front ends ensures that the trolley can be inserted very far into one another, so that they can be parked particularly space-saving.

In a further embodiment, the first side support and the second side support each have a rear end and the support means comprise a second cross member which connects the first side support and the second side support in the region of their rear ends. The use of a second cross member, which is connected in the region of the rear ends with the two side supports, leads to a further increase in the rigidity of the support means.

A further developed embodiment is characterized in that the first side support and the second side support each have an upper surface and the second cross member connects the first side support and the second side support at their upper surfaces. The first cross member and the two side supports of a first transport carriage can be performed under the second cross member of a second transport vehicle. In this embodiment, the gradeability is not affected by the second cross member.

In accordance with a further embodiment, in each case a support column extending essentially perpendicular to the reference plane is fastened in the region of its rear ends to the first side support and to the second side support. In this embodiment, two mounting portions are provided for the tray, so that the two support columns can be dimensioned comparatively small.

A further developed embodiment is characterized in that the two support columns have a U-shaped or C-shaped cross section and the two support columns each enclose a cavity with an open end, the open ends facing each other and the storage tray in the first position at least partially is received in the two cavities. The two support columns are used in this embodiment, not only the support of the shelf, but also to define the first position by the shelf protrudes into the cavities. Elaborate and additional units for defining the first position of the tray are not necessary, so that the structure of the trolley can be kept simple.

According to a further embodiment, the shelf plate at least one projecting into the two cavities guide portion which is formed so that the tray is rotatable with respect to the support columns. The rotation is used to move the shelf between the vertical and the horizontal can. The guide portion may be formed relatively simple and have a circular cross-section, so as to enable on the one hand the linear guide within the cavities of the support columns and on the other hand the rotation between vertical and horizontal. The transfer of the tray from the first to the second position takes place in the following manner in this embodiment: In the first position is the vertically oriented Tray plate on the support device and projects with its lateral edges into the cavities of the support columns. To transfer to the second position, the tray is lifted to the upper end of the support columns until the tray can be rotated in the horizontal. When transferring between the two positions, the storage tray in this embodiment performs both a translational and a rotational movement.

A further embodiment is characterized in that the two support columns each have an open upper end, via which the guide portion can be introduced into the two cavities, and at least one stop element is provided, with which the two upper ends are partially closed, when the guide portion is introduced into the two cavities. The stopper element prevents the guide section from being inadvertently moved out of the cavities when the tray plate is lifted and the shelf plate loses its guidance. In addition, the stop element can be arranged so that there is a feedback for the user, when the tray can be rotated from the vertical to the horizontal, namely, when the guide portion abuts the stop element.

According to a further embodiment, the two support columns each have a shoulder which is dimensioned such that the storage plate is aligned in the second position with the upper ends of the support columns. In this embodiment, a barrier-free storage surface is created, so that in particular flat objects such as wood or metal plates can be stored on the shelf without, for example, disturb the support columns. In particular, wood or metal plates can be placed on the shelf, which protrude beyond the shelf. In this embodiment, the proposed trolley can be used particularly useful as a mobile worktop.
In a further developed embodiment may be attached to the support plate, a support member with which the storage plate is supported in the second position on the support means. Although the support of the tray can also be done exclusively on the support columns, however, in the operation of the trolley, in particular, relatively large torques can act on the support columns when the tray extends far away from the support columns. The support element relieves the support columns and helps to define the second position of the shelf.

In a further developed embodiment, the carrier device has at least one receiving section with which the supporting element can be introduced in the second position. With the receiving portion, the support member can be connected in a clearly defined manner with the support means, so that the user can bring the trolley quickly and easily in the second position.

The 1A to 1E show an embodiment of a trolley 10 , which is particularly useful for storing and transporting objects such as tools and / or workpieces. The dolly 10 has a carrier device 12 on, which is a longitudinal axis L of the trolley 10 defined (see 1B) , At the carrier device 12 There are four wheels in total 14 attached, which is a reference plane e define and as to be perpendicular to the reference plane e running axis swivel castors are executed. Instead of the four wheels can have two wheels 14 and an unillustrated support portion may be provided. Also an execution of the transport vehicle 10 with three wheels 14 is conceivable.

The carrier device 12 includes a first side support 16 and a second side support 18 , each one a front end 20 and a back end 22 have, wherein the two side support 16 . 18 at their front ends 20 with a first cross member 24 connected to each other. The side supports 16 . 18 run in one in the reference plane e lying angle α to the longitudinal axis L to each other, so that the carrier device 12 to the front end 20 the side support 16 . 18 rejuvenated.

As in particular from the 1D shows the carrier device comprises 12 a second cross member 26 with which the two side members 16 . 18 are connected. The two side supports 16 . 18 each have an upper surface 28 on, off the wheels 14 shows away. The second cross member 26 is on the upper surfaces 28 with the two side beams 16 . 18 connected so that the second cross member 26 over the two side beams 16 . 18 and the first cross member 24 is arranged.

At the carrier device 12 are two support columns 30 attached, in the illustrated embodiment, substantially perpendicular to the reference plane e run.

The 2 shows a schematic sectional view through the support columns 30 Approximately along the in 1C defined cutting plane AA. The two support columns 30 have a U-shaped cross section, each with an open end 32 on. The support columns 30 are so on the carrier device 12 attached that open ends 32 show each other. The two support columns 30 each enclose a cavity 34 ,

Furthermore, the transport cart includes 10 a shelf 35 with a distal end 36 and a proximal end 38 , The shelf 35 is between a first position, which in the 1C and 1D is shown, and a second position, which in the 1A . 1B and 1E is shown, movable back and forth on the support columns 30 attached. As in particular from the 2 recognizable, includes the shelf 35 a guide section 40 in the example shown as one at the proximal end 38 the shelf 35 attached round spar 42 is executed. The round spar 42 has a diameter D on, which corresponds approximately to the width of the U-shaped profile. The two support columns 30 each have an open top 44 on (cf. 1E) through which the round spar 42 together with the shelf 35 in the from the two support columns 30 enclosed cavities 34 can be introduced. The two open upper ends 44 can by means of a stop element 46 partially closed, especially if the round spar 42 in the two cavities 34 is introduced.

In the first position, the tray runs 35 approximately perpendicular to the reference plane e , where the round spar 42 on the second cross member 26 rests on ( 1D ). As in particular from the 2 shows, the shelf protrudes 35 in the first position laterally into the cavities 34 into it, so that the support columns 30 the shelf 35 lead and hold in the vertical orientation.

Should the shelf plate 35 be transferred to the second position, the tray is 35 to the upper end 44 the support columns 30 moved out until that round bar 42 on the stop element 46 is applied. The stop element 46 prevents the round spar 42 when transferring the shelf 35 in the second position over the top 44 the support columns 30 is moved out, causing the shelf 35 lose the leadership. If the round spar 42 on the stop element 46 is applied, the tray is 35 turned from the vertical to the horizontal, eliminating the shelf 35 gets into the second position. In the area of the distal end 36 is a support element 48 rotatable on the shelf 35 attached ( 1D ), which in one on the first cross member 24 arranged receiving section 50 can be introduced when the tray 35 located in the second position. The shelf 35 is thereby fixed in the second position.

In particular from 1D shows that the support columns 30 a paragraph 52 have in the region of the upper end, whereby the shelf 35 in the second position flush with the support columns 30 concludes. This also contributes to the fact that the support plate 35 eccentric on the round spar 42 is attached, as in particular in 2 recognizable.

Also the stop element 46 does not protrude above the shelf 35 addition, so that a obstacle-free shelf is created. Consequently, even flat objects, such as wood panels, which are larger than the shelf 35 , easily on the shelf 35 be filed.

The height of the support columns 30 is chosen so that the shelf 35 in the second position at working height, so that it is easily accessible for an employee and he back-friendly objects on the shelf 35 take off and take from her.
