The aim of the invention is that the receiving space can be flexibly adapted and the transport device can be securely locked regardless of the size of the receiving space. To this end, the invention proposes that at least four holes are arranged in pairs or groups over the height of at least one side wall of the base body bordering the insertion opening (2), and that the closure body (4) has at least two fastening openings (6) corresponding to the paired round holes (3) of the base body (1), wherein the round holes (3) on the base body (1) and/or the fastening openings (6) on the closure body (4) have a thread, wherein two bolts can be screwed or inserted into the fastening openings (6) or round holes (3) such that the base body (1) and the closure body (4) are positively connected.

Description

The invention relates to a transport device for flat objects, in particular for paintings, art prints and/or posters stretched on stretcher frames, with a cuboid-shaped base body in which a receiving space for at least one flat object is formed and which has an insertion opening on one side through which the flat object can be inserted into the receiving space, wherein the transport device comprises a cuboid-shaped closure body which can be pushed onto the base body so that the closure body at least partially covers the base body and can be fixed to the base body to close its insertion opening.

Such a transport device is known, for example, from the publication EN 10 2019 110 894 A1 known. The transport device described there is used for transporting and storing flat objects, especially works of art. In order to protect the works of art from damage, the receiving space described there is at least partially padded. Furthermore, the base body and the closure body can be connected in a form-fitting manner via ribs and corresponding recesses.

To protect the transport device and its contents from unauthorized access, the EN 10 2019 110 894 A1 proposes to provide corresponding eyelets on the closure body and the base body, which can be connected by means of a cable tie or lock.

The disadvantage of the options described there for attaching the closure body to the base body is that the transport device only has a receiving space of a predetermined size. The connection between the base body and the closure body is also not stable because it is only realized by the two bodies themselves and their integral components.

It is therefore an object of the invention to provide a transport device whose receiving space can be flexibly adapted and which can be locked independently of the size of the receiving space, wherein the transport device should also be easy to operate.

To solve the problem, the invention proposes, starting from a transport device of the type mentioned at the outset, that at least four holes are arranged in pairs or groups over the height of at least one side wall of the base body adjacent to the insertion opening and that the closure body has at least two fastening openings corresponding to the paired round holes of the base body, wherein the round holes on the base body and/or the fastening openings on the closure body have a thread and wherein two bolts can be screwed or inserted into the fastening openings or round holes, such that the base body and the closure body are positively connected.

The round holes on the base body, which are distributed in pairs or groups over the height, make it possible to push the locking body onto the base body to such an extent that a pair or group of round holes on the base body is aligned with the at least two fastening openings on the locking body. The bolts can then be inserted so that the locking body is secured to the base body. The bolts can be locked in the round holes using the blocking mechanism. The blocking mechanism can only be opened again by an authorized person. The storage volume of the transport device according to the invention can thus be easily adjusted and adapted for flat objects of different sizes. It is also possible to protect the object from unauthorized access.

A preferred embodiment of the invention provides that the round holes on the base body are distributed over at least 80%, preferably over at least 90% of the height of the base body. This allows the receiving volume to be increased in a particularly advantageous and flexible manner.

A particularly preferred embodiment of the invention provides that the distances between the round holes are the same and are a maximum of 75 mm, preferably a maximum of 55 mm. This ensures that a round hole can always form a pair with the round hole arranged above and below it, so that the flexibility is further increased without any design effort.

The blocking mechanism is preferably designed using bolts in the form of eyebolts and a U-lock that runs through the eyelets of the eyebolts. This design reliably prevents the eyebolts from being unscrewed. The construction is robust and easy to use.

Alternatively, the blocking mechanism is designed using bolts in the form of at least two locking bolts with an axial lock. The axial lock ensures a positive connection between the base body and the locking body.

A further development of the invention provides that one or more fold-out holding brackets, preferably two holding brackets, and/or at least one handle are arranged on the outer surface of the closure body. For example, a carrying strap with a snap hook can be attached to the folded-out holding brackets so that the user can comfortably carry the transport device over the shoulder during transport. When the holding brackets are not in use, they are folded in and preferably sunk into a recess in the closure body. The same principle applies to a handle that is arranged on the insertion opening on the outer surface of the closure body, which can be grasped directly by hand during transport and preferably has an ergonomic shape.

It is useful if the closure body and/or the base body are made of plastic, preferably polyethylene. The transport device therefore remains relatively light overall and yet is very robust against environmental influences, so that the flat object is safely protected. In addition, the closure body and the base body can be made of plastic using the rotation process. The rotation process offers a particularly precise and yet cost-effective manufacturing method.

Advantageously, the closure body and/or the base body have padding on their inner surfaces. The padding provides additional protection for the flat object against impacts during transport.

In 1a and 1b the individual parts of a transport device according to the invention are shown in an exploded view. The cuboid-shaped base body is designated with the reference number 1. The base body 1 consists essentially of polyethylene and has an insertion opening 2 on one side, which extends over the entire side. A flat object can be inserted into the base body 1 via the insertion opening 2. The base body 1 has round holes 3 over the height of its narrow sides. The round holes 3 have an internal thread. Each round hole 3 forms a pair with the neighboring round holes 3. The round holes 3 on the base body 1 are in 2a and 2b visible.

Furthermore, a cuboid-shaped closure body 4 is shown. The closure body 4 is also made of polyethylene and has a slide-on opening 5 on one side, which extends over the entire side. On the narrow sides, two fastening openings 6 are provided at the lower end, which are not visible in this front view. The fastening openings 6 correspond to the round holes 3 on the base body 1, i.e. have the same or a slightly larger diameter and the same distance from one another.

In addition, the transport device in this embodiment has bolts that are designed as eyebolts 7.1. Finally, a U-lock 8 is shown. The embodiment with plug bolt 7.2 with axial lock 7.2.1 in 1b cannot be locked, but can be opened and closed much quicker.

During use, a flat object is inserted into the receiving space of the base body 1 via the insertion opening 2. The closure body 4 is then at least partially placed over the base body 1 so that the flat object is surrounded by the base body 1 and the closure body 4. The closure body 4 is pushed onto the base body 1 so far that the transport device as a whole accommodates the flat object as precisely as possible and the two fastening openings 6 of the closure body 4 are located exactly over two round holes 3 of the base body 1. As in 2a and 2b shown, the eyebolts 7.1 or the plug bolts 7.2 with axial lock 7.2 are then guided through the fastening openings 6 and screwed into the round holes. The base body 1 and the locking body 4 are now positively connected by means of the eyebolts 7.1 or the plug bolts 7.1 with axial lock 7.2.1.

Finally, the bolt of the U-lock 8 is guided through the eyelets of the eyelet screws 7.1 and the U-lock 8 is closed. The flat object is now safely protected from environmental influences and access by unauthorized persons in the transport device, as shown in 3a shown.

3b shows the transport device closed by means of locking pins in a detailed view.

4a shows the transport device 1 in a first orientation. The locking body 4 is pushed onto the base body 1 so far that the two fastening openings 6 on the locking body 4 are located exactly above the two lowest round holes 3 on the base body 1. The eyelet screws 7.1 are guided through the fastening openings 6 and screwed into the two lowest round holes 3. The U-lock 8 is guided through the eyelets of the two eyelet screws 7.1 and locked. The eyelet screws 7.1 can no longer be turned due to this blocking mechanism. The flat object in the transport device is protected as described above. The transport device has its minimum storage volume in this orientation.

4b shows the transport device 1 in a first orientation. The closure body 4 is pushed onto the base body 1 so far that the two fastening openings 6 on the closure body 4 are located exactly above the two lowest round holes 3 on the base body 1. The plug pins 7.2 with axial lock 7.2.1 are guided through the fastening openings 6 and screwed into the two lowest round holes 3. The plug pins 7.2 with axial lock 7.2.1 can no longer be unscrewed due to this blocking mechanism and connect the closure body 4 to the base body 1 in a form-fitting manner. The flat object located in the transport device is protected as described above. The transport device has its minimum storage volume in this orientation.

5 shows the transport device 1 in a second orientation. The locking body 4 is pushed onto the base body 1 so far that the two fastening openings 6 on the locking body 4 are located exactly above the top two round holes 3 on the base body 1. The eyebolts 7.1 are guided through the fastening openings 6 and screwed into the top two round holes 3 on the base body 1. The U-lock 8 can now be guided through the two eyebolts 7.1 and locked. The transport device has its maximum storage volume in this orientation.

The two orientations show the inventive principle of the transport device, which offers a variable receiving volume and at the same time very good protection for the respective flat object.

6 shows a detailed view of an upper edge of the closure body 4. A retaining bracket 9 is shown on the top. This can be adjusted from a flat position to an unfolded position (as shown) by means of a folding mechanism. For example, a carrying strap can be hooked into the retaining bracket 9 by means of a snap hook. A second corresponding retaining bracket 9 is arranged at the opposite end of the top of the closure body 4.

Finally, a fold-out handle 10 is arranged in a recess in the side wall of the closure body 4. A second fold-out handle 10 of this type is arranged on the opposite side wall of the closure body. By means of the fold-out support bracket 9 or the fold-out handle 10, the transport device can be carried particularly comfortably with both hands or by two people.

7 shows a cross-section through a round hole 3 of the base body 1 with an inserted plug pin 7.2 with an axial lock 7.2.1. The diameter of the shaft of the plug pin 7.2 is selected so that the plug pin fits precisely into the round hole 3. While the axial lock 7.2.1 engages in an axial widening of the round hole so that the plug pin 7.2 is positively connected to the base body 1 The axial lock 7.2.1 can be retracted and the plug pin 7.2 can be pulled out of the round hole 3 via an actuating mechanism (not shown here) on the plug pin 7.2, preferably arranged on the head of the plug pin 7.2.
