At least two front castors are arranged on the chassis in the area of the front and at least two rear castors are arranged in the area of the rear. The pivotability of the castors about the vertical axis can be blocked or at least restricted by a mechanism.

A swivel castor with a directional lock is from the German utility models DE 712 9463 U and DE 82 12 074 U1 known. The castor wheel has a locking element and a locking counter-element, which are movable between an engagement position and a release position.

OBJECT OF THE INVENTION

The invention has for its object to provide a movable loading lift with which goods can be easily and flexibly both safely transported over routes and exactly positioned at the destination.

SOLUTION

The object of the invention is achieved according to the invention with the features of the independent claims.

Further preferred configurations according to the invention can be found in the dependent patent claims.

DESCRIPTION OF THE INVENTION

The invention relates to a movable loading lift for picking up, moving, lifting and lowering goods. The loading lift has a chassis with a front lying in the forward direction and a rear lying in the forward direction. A lifting unit with a mast and a receiving device for receiving the goods is arranged on the chassis. A motor is connected to the lift unit. An operating unit for moving the loading lift and for moving the receiving device by means of the motor in the vertical direction along the mast for lifting and lowering is arranged in the area of the rear. At least one front castor is arranged on the chassis in the area of the front and at least one rear castor is arranged in the area of the rear. The movable loading lift has a swivel locking unit for the front swivel castor and / or the rear swivel castor. The swivel locking unit has a remote control element which is arranged in the area of the rear. The swivel locking unit each has a locking element for the at least one front swivel castor and / or the at least one rear swivel castor, which works together with a counter locking element of the front swivel castor or rear swivel castor. The swivel locking unit is designed and arranged such that the locking element can be moved between an engagement position and a release position by actuating the remote control element.

With such a movable loading lift, the operator stands behind the rear of the loading lift and operates it with his hands via the control unit arranged there. The control unit is used for motor-driven lifting and lowering of the holding device along the mast of the lift unit. However, the operating unit can additionally have one or more mechanical handles which are used to generate the actual travel movement of the loading lift by the operator pressing or pulling on the handles. In this case, the charging lift does not have a motor-driven travel drive. However, it is also possible for the loading lift to have such a motor-driven travel drive and for the movement to be generated without muscle power.

The mobile loading lift is used in particular in logistics and for the transport and handling of goods that have a mass in a range from approximately 30 to 600 kg. It is a lifting aid for such goods and not a construction vehicle, such as a crane or even a heavy-duty crane. A typical application is the handling of wheels when they are mounted on the motor vehicle.

The motor connected to the lift unit is in particular an electric motor. This is supplied with energy by means of a rechargeable battery or an accumulator.

The component referred to in this application as the “front swivel castor” or “rear swivel castor” is not only the castor body that can be rotated to generate the travel movement of the movable loading lift, but also the cage surrounding it, the bearing, the mounting flange, etc. One could therefore speak of the "front castor unit" or "rear castor unit". For the sake of simplicity, however, the term “front castor” or “rear castor” is used in this application. The swivel castor can also be a steerable wheel.

The new movable loading lift has a central swivel locking unit or several central swivel locking units for the front swivel castor and / or the rear swivel castor.

In contrast to directional locks of the prior art, the swivel castor is switched over to a fixed castor and vice versa not directly on the respective castor but at a distance from it. If there are several front castors and these can be switched, the switch is preferably made jointly and simultaneously for the front castors. If there are several rear castors and these are switchable, the switch is preferably carried out jointly and simultaneously for the rear castors. If both the front swivel castors and the rear swivel castors can be switched, the switchover can either be carried out jointly and simultaneously for the front swivel castors and the rear swivel castors or separately.

In addition, the actuation is carried out via at least one remote control element, which is arranged within the reach of the normal location of the operator of the movable loading lift. The operator's area is the area of the rear of the loading lift and its surroundings. More precisely, the operator is behind the rear of the loading lift when operating. The operator therefore does not have to go forward to actuate the front castors in the sense of switching from the freely pivotable position to the locked position and vice versa. This means that switching can be done easily and conveniently while driving with the mobile loading lift. If the rear swivel castors are designed to be switchable, this switchover is also convenient.

The swivel locking unit has several components that can be mounted on different parts of the loading lift. However, the swivel locking unit is at least also arranged on the chassis, the mast or the control unit. The swivel locking unit is therefore not exclusively part of the front castors or rear castors.

In the operating position of the operator, the operator is at a maximum distance from the front castors. If the movable loading lift is to be moved over a comparatively large distance, for example to drive to the location where there is a good to be transported, the loading lift must be positioned exactly by simultaneously pivoting both the front castors and the rear Swivel castors not required. Such a simultaneous swiveling is even a hindrance and difficult and delays the reaching of the destination when driving straight ahead. The same applies if the goods to be transported have already been picked up and are now being brought to their new destination.

The new central swivel locking unit for the front swivel castor (s) and / or the rear swivel castor (s) therefore enables the operator to change the swivel castor (s) in a simple and convenient manner without leaving his position behind the rear of the loading lift. that they are in their engaged position. If the respective locking element of the swivel locking unit then engages in the associated locking counter-element of the respective steering roller (“engaging position”), the steering rollers can no longer pivot about the vertical axis and thus facilitate straight-ahead driving. The pivotability of the other castors is sufficient to implement the required cornering.

When the operator has reached the place where more sensitive handling of the goods is required, he can release the steering roller (s) in the same simple manner by actuating the remote control element from his position behind the rear of the loading lift. If two front castors are available and can be switched, they are released together and at the same time, so that they can turn around their vertical axes again. The same applies to switchable rear castors. With the now four freely swiveling castors, the loading lift can be positioned precisely and delicately. The loading lift can also be moved sideways.

The movable loading lift can have at least one front swivel castor which can be temporarily converted into a fixed castor by means of the swivel locking unit. This is particularly possible with a centrally positioned front leg. But there can also be more than two switchable front castors. This is particularly possible with two symmetrically arranged front legs. It is also possible that the loading lift has more than two front castors - e.g. B. four, six or eight front castors. All or only a part of these can be temporarily converted into fixed castors by means of the swivel locking unit.

If the rear swivel castors can also be temporarily converted into fixed castors, this is done using the swivel locking unit of the front swivel castors or an additional swivel locking unit.

The swivel locking unit moves the at least one locking element between an engagement position and a release position. The release position is understood to mean that the swiveling of the steering roller about the vertical axis is immediate. The same does not necessarily apply mutatis mutandis to the engagement position. For example, the engagement position can only mean that the locking element has changed its position relative to the release position, but the actual intervention in terms of preventing the swivel castor from pivoting about the vertical axis (“engaging position”) does not yet exist, since the countermember of the castor wheel does not exist located in the engagement area of the locking element.

It is possible that the locking element is not part of the steering roller. The locking element is instead part of the swivel locking unit and only interacts with the respective steering roller. The swivel castor can therefore be designed like a normal swivel castor with the exception of the locking counter element. The swivel castors of a movable loading lift are wearing parts. With the new loading lift, they can be replaced easily and inexpensively without having to replace parts of the swivel locking unit. The only part to be exchanged is the locking counter element, which however is not part of the swivel locking unit according to the definition of this application.

It is possible that the respective locking element is not connected to the respective steering roller. This means that there is no fixed connection between the locking element and the respective steering roller. However, these two parts touch to produce the engaged position. To dismantle the swivel castor, it only has to be released from the chassis and not from the swivel locking unit. This enables assembly and disassembly of the swivel castors which does not take longer than in the prior art without a swivel locking unit.

The locking elements and the respectively assigned locking counter-elements can be designed and arranged in one another for a positive engagement. The engagement position is thus realized by a form fit. The locking element can have a protruding part and the locking counter element can have a recessed part. The protruding part may e.g. B. act a nose, a paragraph, a pawl, a bolt, a pin, etc. The exempted part may be e.g. B. a recess, a recess, a groove, etc. act. However, it is also possible that the reverse constellation is present.

The positive connection can be designed so that it can be fixed between the locking element and the locking counter-element in different angular positions. Examples of such angular positions are angles of 0 °, 45 ° and 90 °. It is therefore possible to secure not only straight-ahead travel at an angle of 0 °, but also other positions. In the 90 ° position, forward and reverse travel are prevented. With a corresponding angular adjustment of the rear swivel castors as well, the loading lift can be secured against unwanted movement.

The swivel locking unit can be designed and arranged in such a way that the locking element does not engage in the associated locking counter-element in the release position and the swivel castor can thus be pivoted in the sense of changing the direction of travel of the movable loading lift. In the release position, there is therefore no positive engagement between the locking element and the locking counter-element. These elements either do not touch at all or only in such a way that the relative movement is not prevented. The castor can thus pivot freely about its vertical axis.

The swivel locking unit can be designed and arranged such that the locking element engages in the engaged position in the associated locking counter-element, provided that the steering roller is in a locking pivoting position, and the steering roller is therefore not pivotable in the sense of preventing the direction of travel of the movable loading lift from changing. Assuming the engaged position does not therefore necessarily mean that the pivotability of the steering roller has already been eliminated. For this, the (still) swivel castor must be swiveled into a locking swivel position. In the example described above, locking at 0 ° (or 180 °) must be done so the castor can be brought into this position. This can be achieved simply by the operator moving the loading lift with appropriate swivel movements and thereby automatically adjusting the locking swivel position of one or both front castors. When this locking pivot position is reached, the actual positive engagement between the locking element and the locking counter element then takes place automatically. This can be caused, for example, by a spring force.

The swivel locking unit can have mechanical connecting means, in particular Bowden cables or rods, which connect the remote control element to the locking elements. In this way, the actuation signal entered by the operator via the remote control element is transmitted to the locking elements. This can be implemented, for example, in such a way that separate mechanical connecting means are connected to the respective locking element on both sides of the loading lift. These initially separate mechanical connecting means are then preferably routed centrally to the remote control element. However, it is also possible, for example, for this vertical section to be bridged by only one mechanical connecting means, while there is a mechanical connecting means for each side in the horizontal section.

However, the swivel locking unit can also have electrical connecting means, in particular electrical lines, an electric motor and mechanical connecting means, the electrical connecting means connecting the remote control element to the electric motor and the mechanical connecting means connecting the electric motor to the locking elements. In this way, the power transmission between the electric motor and the locking elements takes place mechanically, but without muscle power, while the actuation of the electric motor takes place on the basis of an electrical signal triggered by the operator. The electric motor can e.g. B. act as a linear motor. In the mechanical fasteners it can be, for. B. act flexible cables, wires, etc. or a rigid linkage.

The chassis can have two spaced front legs in the region of its front, at the end of which one of the front castors is arranged. The mechanical connection means can then be guided through the inside of the front legs. This effectively prevents damage to the mechanical connection means and at the same time creates a tidy visual impression.

The triggering of the operating command in the sense of moving the locking element between the engagement position and the release position can be carried out not only by the operator but also by an electrical or electronic control unit. For example, a switching command can be triggered simultaneously by the engine control unit in the motorized movement of the recording unit. Another example is the release position is always triggered when the lift movement is slow and / or close to the component by means of speed sensors and / or distance sensors.

It is possible that not only the locking elements can be moved alternately between the engagement position and the release position by means of the remote control element or an additional remote control element, but also the castors are braked.

The swivel locking unit can be designed such that the engagement position of the locking elements is automatically assumed when the swivel locking unit is in an inactive position. However, it is also possible for the release position to be adopted automatically instead. The mechanical connection means, e.g. B. the Bowden cable or the linkage, can in particular be connected to a return spring so that when the Bowden cable or the linkage is relieved, the engagement position is automatically assumed.

The remote control element is arranged in the area of the rear of the loading lift. It can on the control unit, for. B. on the handlebar. But it can also be arranged on the chassis, the mast, the battery or another part arranged there.

It is also possible that further levers or switches are arranged in the area of the remote control element, by means of which additional functions of the movable loading lift can be activated and deactivated. Such additional functions are e.g. B. a warning light or an additional drive.

The simultaneous actuation of both locking elements can take place in particular via a double pull lever or a Y cable or Y linkage. In the case of the double pull lever, two bowden cables of the same length are pulled at the same time by operating the lever, each leading to one of the locking elements. With the Y connection, the Bowden cable or linkage is divided into two cables or linkages via a distributor in order to control the locking elements at the same time.

If the movable loading lift has a motor, in particular an electric motor, for actuating the swivel locking unit, in particular a traction motor with a spindle or a traction Electromagnet can be used. For this purpose, the motor or the electric train electromagnet can be located directly on the locking element, e.g. B. inside the foreleg. An adjacent arrangement is also possible. It is controlled via a common electrical signal. Control by means of an upstream Bowden cable or linkage is also possible. The engine sits z. B. in the housing under the lift unit. This allows the front legs to be made slimmer. Accessibility is simplified in the event of a repair. In addition, you can only use one motor that simultaneously controls two Bowden cables or rods in the sense of the Y arrangement described above.

FIGURE DESCRIPTION

1-7 show different views of a first exemplary embodiment of a new movable loading lift 1 for picking up, moving, lifting and lowering goods. 1 shows an isometric view of the movable loading lift 1 in which its overall arrangement is clearly recognizable.

The mobile loading lift 1 has a chassis 2nd with one in the forward direction 3rd seen front lying front 4th and one in the forward direction 3rd seen rear stern 5 on.

The chassis 2nd has different supports or profiles, two of which are in the area of the front 4th spaced front legs 6 belong. The front legs 6 extend parallel to the forward direction 3rd .

Approximately in the front end area of the front legs 6 and thus in the area of the front 4th is on each of the front legs 6 one front swivel castor each 7 arranged. With the front swivel castor 7 it is not only the one for generating the travel movement of the movable loading lift 1 rotatable roller body, but also the cage and the necessary parts. In contrast to a non-steerable fixed castor, a swivel castor is characterized in that it is pivotable about a vertical axis to enable cornering. In this case, the steering angle is not specified by a motor, but instead arises due to the operation of the movable loading lift 1 by the operator. However, it could also be predetermined by means of a control unit and a drive.

In the area of the opposite tail 5 are spaced hind legs 8th intended. On each of the hind legs 8th is a rear swivel castor 9 arranged.

On the chassis 2nd is a lift unit 10th with a mast extending substantially vertically upwards 11 and a cradle 12th arranged for receiving the goods. The lift unit 10th is with an engine 13 connected, which is designed as an electric motor and in turn with a battery 14 is connected and driven by this.

The mobile loading lift 1 still has one in the area of the stern 5 arranged control unit 15 for moving the loading lift 1 over the floor and for moving the cradle 12th by means of the engine 13 in the vertical direction along the mast 11 for lifting and lowering. The control unit 15 has a handlebar 16 with handles arranged on both sides 17th which are gripped by the operator's left and right hands when the operator is behind the stern 5 of the movable loading lift 1 stands and this by means of the handles 17th pulls or pushes. The actual movement of the loading lift 1 is generated manually by the operator. But it would also be possible for the control unit 15 Has controls for actuating a travel drive and possibly steering drive.

The control unit 15 still has a lift control 18th on which by means of an electrical line 19th with the engine 13 connected is. With the lift control 18th becomes the cradle 12th Move up and down in the vertical direction.

These previously described elements of the movable loading lift 1 are from the German patent application DE 10 2015 115 392 A1 the applicant ring known and are therefore not described in more detail below.

On the chassis 2nd and the lift unit 10th is a swivel lock unit 20th for the two front castors 7 arranged. The swivel locking unit 20th has a remote control 21 on that in the area of the stern 5 is arranged. In the present case, the remote control element 21 in the area of the control unit 15 arranged to allow easy operation. But it would also be possible to use the remote control 21 in another area of the tail that is easily accessible to the user 5 to arrange.

In the present example, it is the remote control element 21 around a remote control lever 22 with a Bowden cable 23 connected in a spout 24th is led. The Bowden cable 23 and the spout 24th are on the mast 11 down and through the front legs 6 forward to the front swivel castors 7 guided. This is done by operating the remote control lever 22 the operation of both front castors described below 7 at the same time.

The more precise function of the swivel locking unit 20th is now described in the following in particular with the help of 3rd , 4th and 6 , 7 explained. The swivel locking unit 20th points for the two front castors 7 one locking element each 25th on. The locking element 25th is not part of the respective front swivel castor 7 . Rather, it is a part of the chassis 2nd is attached.

In the example shown here is the locking element 25th as a locking bolt 26 trained the one with the Bowden cable 23 connected is. Using a console 27 is the locking bolt 26 on the chassis 2nd attached. The console 27 allows the locking bolt to move back and forth 26 depending on the actuation by the Bowden cable 23 . It is still a feather 28 arranged the locking bolt 26 when the Bowden cable is released 23 to the right (see 3-7 ) acted upon. The console 27 is by means of screw connections 29 with the chassis 2nd Non-destructively detachably connected.

The respective front swivel castor 7 points to the locking element 25th corresponding trained locking counter element 30th on. In the present case, it is a locking recess 31 that are in an extension 32 the front swivel castor 7 is formed.

The function of the new swivel locking unit 20th is good based on a comparison of 3rd and 4th With 6 and 7 comprehensible. 3rd and 4th show the release position of the locking element 25th , while 6 and 7 the engagement position of the locking element 25th and even the engagement between the locking element 25th and the locking counter element 30th demonstrate. It is between the engaged position of the locking element 25th and the engaging position between the locking element 25th and the locking counter element 30th to distinguish. This is because the engagement position of the locking element 25th just means the locking element 25th would be able to engage the counter locking element 30th to manufacture. However, the actual intervention only takes place when the locking counter element is also in place 30th in the appropriate position.

In 3rd and 4th is the locking element 25th in the release position so that the front swivel castor 7 can freely pivot around its vertical axis in order to take a curve with the movable loading lift 1 to enable. It can be seen that there is no contact between the locking element 25th and the locking counter element 30th consists. In particular, the locking bolt engages 26 not in the locking recess 31 on. This release position is achieved by using the remote control lever 22 the Bowden cable 23 is tightened so that the locking bolt 26 against the force of the spring 28 from the front swivel castor 7 moved away. This position engages and is held until the Bowden cable 23 using the remote control lever 22 is released.

The engagement position of the locking element thereby achieved 25th is in the 6 and 7 shown. It can be seen that the locking bolt 26 due to the force of the spring 28 towards the front swivel castor 7 has moved and now with its free end in the locking recess 31 in the extension 32 the front swivel castor 7 intervenes. Through this intervention, the front swivel castor 7 no longer pivot about its vertical axis. The swiveled position is thus retained until the remote control lever 22 is pressed again.

8-13 show different views of a second exemplary embodiment of the new movable loading lift 1 . In this case, the swivel locking unit 20th a differently designed locking element 25th on. Instead of the locking bolt here is a locking spring designed as a leaf spring 33 available. The locking spring 33 is by means of a clamping device 34 with the Bowden cable 23 and the spout 24th connected. At its other end is the locking spring 33 by means of a fastening device 35 on the chassis 2nd Non-destructively detachably connected.

In this case, this takes over as a locking spring 33 trained locking element 25th thus at the same time the function of the spring of the other exemplary embodiment. Regarding the in 9 and 10th shown release position and in 12th and 13 shown engagement position is referred to the above statements.
