Description

[0001] The present invention relates to a protective device for a door leaf, in particular for protecting the door leaf during transport, during assembly and after assembly.

[0002] Such a protective device can be packaging that encloses the door leaf during transport. However, the protective device can also at least partially enclose or cover the door leaf during and after installation, thus protecting it from damage.

[0003] A protective device that wraps a door leaf during transport is known, for example, from document DE 20 2019 106 215 U1. The document discloses reusable packaging for at least temporarily repacking the door leaf. This repackaging serves in particular to protect the door on site from any damage caused by pending construction, renovation, or refurbishment work. The renewed protection of the door leaf using door packaging can be achieved both during installation, i.e., when it is not yet installed, and after the door leaf has been installed, i.e., when it is installed. In the light of document DE 20 2019 106 215 U1, "after installation" means that the door leaf is hung in an existing door frame and the door is open. The repackaged door cannot be closed. This is a disadvantage in many cases.

[0004] The protective device known from the document DE 20 2019 106 215 U1 has a first wall, a second wall, a third wall, a fourth wall, a fifth wall and a sixth wall, wherein • the first wall and the second wall are arranged at a first distance and parallel to each other, • the third wall and the fourth wall are arranged at a second distance and parallel to each other, • the fifth and sixth walls are arranged at a third distance and parallel to each other, • the third, fourth, fifth and sixth walls connect the first wall and the second wall and • the third, fourth, fifth and sixth walls form a strip with a width corresponding to the first distance, and • has predetermined breaking points or predetermined breaking lines, in particular material weaknesses or perforations, at or along which the protective device can be torn open.

[0005] The protective device known from document DE 20 2019 106 215 U1 has, among other things, predetermined breaking lines in the first wall and the second wall in areas where handle sets are attached to the door leaf. The first and second walls can be opened via these predetermined breaking lines in order to mount the handle set on the otherwise still packaged door leaf. This makes it possible to mount the handle set in an otherwise largely packaged state of the door leaf at a location that is not the location where the door leaf is installed. This makes it possible to mount the door handle set in a location that is more suitable than the location where the door leaf is installed in the building. The door, which is thus largely packaged, can be brought to the location where the door leaf is installed with the handle set installed. The door leaf is then also protected during transport to the location where the door leaf is installed.

[0006] In addition to a handle set, other fittings are sometimes attached to door leaves on construction sites. However, this requires unpacking the door leaf from its usual packaging and separating the packaging from the door leaf. This is also a disadvantage of the usual packaging.

[0007] The invention was therefore based on the problem of improving the known packaging.

[0008] This problem is solved in that a part of the first wall of a protective device according to the invention according to claim 1 forms a first protective cover for a closing side of the door leaf, which is separable from the remaining protective device, wherein this part has a smaller area than the first wall and wherein the first protective cover is delimited by a first, second, third and fourth predetermined breaking line of the predetermined breaking lines and a. wherein the first predetermined breaking line runs along an edge between the first and third walls or at a distance from and parallel to an edge between the first and third walls, b. wherein the second predetermined breaking line runs along an edge between the first and fourth walls or at a distance and parallel to an edge between the first and fourth walls, c. wherein the third predetermined breaking line runs along an edge between the first and the fifth wall or at a distance and parallel to an edge between the first and the fifth wall and d. wherein the fourth predetermined breaking line runs along an edge between the first and sixth walls or at a distance from and parallel to an edge between the first and sixth walls.

[0009] The protective device provides the first protective cover with which the closing side, often also referred to as the counter-hinge side, of the door leaf suspended in the frame can be covered. This first protective cover is smaller than the first wall of the protective device. This is necessary so that the first protective cover for the closing side only covers the part of the closing side of the door leaf that is visible when the door is closed. If the first protective cover were larger than or the same size as the closing side, the first protective cover would also extend into the area where the frame seal rests on the door leaf. The first protective cover would then prevent the door from closing or at least make it very difficult to do so.For this reason, the first protective cover formed from the protective device according to the invention for the closing side of a door leaf is smaller than the closing side of the door leaf, both in the case of rebated doors and in the case of flush-fitting doors.

[0010] This problem is also solved in that a part of the second wall of a protective device according to the invention according to claim 2 forms a second protective cover for an opening side of the door leaf, which second protective cover can be separated from the remaining protective device, wherein this part has a smaller area than the second wall or has an area of the same size as the second wall and wherein the second protective cover is limited by a fifth, sixth, seventh and eighth predetermined breaking line of the predetermined breaking lines and a. that the fifth predetermined breaking line runs along an edge between the second and third walls or at a distance and parallel to an edge between the second and third walls, b. that the sixth predetermined breaking line runs along an edge between the second and fourth walls or at a distance and parallel to an edge between the second and fourth walls, c. that the seventh predetermined breaking line runs along an edge between the second and the fifth wall or at a distance and parallel to an edge between the second and the fifth wall and d. that the eighth predetermined breaking line runs along an edge between the second and sixth walls or at a distance from and parallel to an edge between the second and sixth walls.

[0011] In contrast to the first protective cover, which is smaller than the first wall of the protective device, the second protective cover can be the same size as or smaller than the second wall of the protective device. Since the opening side of a door leaf does not touch the frame when the door is closed, the second protective cover can also be formed from the second wall.

[0012] The first and second protective covers of a protective device according to the invention can protect the closing side and the opening side of a door leaf. It is possible for only the first protective cover to be used to protect the closing side, or only the second protective cover to protect the opening side. Both protective covers can also be used simultaneously.

[0013] The problem can further be solved by providing ninth predetermined breaking lines of the predetermined breaking lines in the third wall of a protective device according to the invention according to claim 3, and said ninth predetermined breaking lines delimit two first regions which are spaced apart from one another and from the edge between the third and fifth walls and from the edge between the third and sixth walls.

[0014] In order to be able to mount hinges on a door leaf protected by a protective device according to the invention in addition to a door handle fitting, the first two areas can be cut out of the third wall. This makes it possible to access the points on the packaged door leaf where the hinges are inserted into the door leaf. The door can therefore remain largely protected by the protective device when the door hinges are mounted on the door leaf. This makes it possible to provide hinges to door leaves arranged in a stack and wrapped in a protective device according to the invention without having to unpack the door leaves. This makes it possible for the door leaves to be placed in a stack protected by the protective device and still allow the hinges to be mounted.

[0015] The first wall and / or the second wall of a protective device according to the invention can have tenth predetermined breaking lines. These tenth predetermined breaking lines can delimit a second region in each of the two walls, which is at a distance from the edge between the first or second and the fifth wall and from the edge between the first or second and sixth wall. These second regions can be completely or partially severed from the first and / or second wall if a door handle set or door handles or the like are to be mounted on the door leaf arranged in the protective device. These tenth predetermined breaking lines can begin either at an edge between the first or second wall and the third wall or at an edge between the first or second wall and the fourth wall and run perpendicular to this edge.

[0016] In a preferred embodiment, a protective device according to the invention is designed so that a. the first predetermined breaking line runs along the edge between the first and third walls, b. the second predetermined breaking line runs at a distance and parallel to the edge between the first and fourth walls, c. the third predetermined breaking line runs along an edge between the first and fifth walls and d. the fourth predetermined breaking line runs at a distance and parallel to the edge between the first and sixth walls.

[0017] Furthermore, in the case of one or the preferred protective device mentioned in the previous paragraph a. the fifth predetermined breaking line runs along the edge between the first and third walls, b. the sixth predetermined breaking line runs along the edge between the first and fourth walls, c. the seventh predetermined breaking line runs along an edge between the first and fifth walls and d. the eighth predetermined breaking line shall be spaced apart and parallel to the edge between the first and sixth walls.

[0018] It is not necessary for the aforementioned weak lines to run across the entire height or width of the protective device. Rather, it is possible for the weak lines to be followed by cut or fold lines along which the protective device is cut or bent.

[0019] Also according to the invention is an arrangement comprising a door leaf and a protective device according to the invention, wherein the door leaf is arranged between the walls of the protective device.

[0020] In an arrangement according to the invention, the first regions can be cut out of the third wall. This creates holes in the third wall. These holes allow access to first receptacles for hinges provided in the door leaf. The hinges inserted in the first receptacles can extend through the holes in the wall.

[0021] In an arrangement according to the invention, the second regions can be cut out of the first and / or second wall. This creates holes in the first and / or second wall. These holes allow access to second receptacles for a door handle assembly provided in the door leaf. Parts of the door handle assembly inserted into the second receptacles can protrude through these holes in the first and / or second wall.

[0022] Furthermore, further protection of the door leaf is provided by an arrangement comprising a door leaf and the first protective cover separated from a protective device according to the invention. The first protective cover is attached to the door leaf in such a way that it largely covers the closing side of the door leaf. In particular, the surfaces of the closing side of the door leaf that rest against a seal of the frame when the door is closed are not covered.

[0023] Further protection of the door leaf is achieved by an arrangement of a door leaf and the second protective cover separated from a protective device according to the invention in that the second protective cover is fastened to the door leaf in such a way that it completely or largely covers the opening side of the door leaf.

[0024] Preferably, the first protective cover and / or the second protective cover can be attached to the door leaf with adhesive film strips.

[0025] Further features and advantages of embodiments of the invention are described below with reference to the schematic drawings.

[0026] It is not necessary for a protective device according to the invention or a cardboard blank for a protective device according to the invention to have all of the features described below. It is also possible for a protective device according to the invention or a cardboard blank for a protective device according to the invention to have only individual features of the exemplary embodiments described below.

[0027] The cardboard blank for the first protective device is essentially rectangular. It is notched at two corners.

[0028] The cardboard blank for the first protective device has cutting lines, a predetermined breaking line and fold lines. The cutting lines are shown in the Fig. 1 and Fig. 4 solid, the break line is dashed in the figures and the fold lines in the Fig. 1 and Fig. 4 is shown in dotted lines. The predetermined break lines are perforation lines. The cardboard blank is folded 90° along the fold lines to produce the first protective device. The cardboard blank is also folded 90° along some of the predetermined break lines to produce the first protective device. These will be explained later.

[0029] In the presentation of the Fig. 1, the cardboard blank for the first protective device has, from right to left, a first flap L1, the first wall W1, the third wall W3, the second wall W2 and a second flap L2.

[0030] In the presentation of the Fig. 1, a third tab L3 is connected to the first wall W1 at the top and a fourth tab L4 at the bottom. A fifth tab L5 is connected to the second wall W2 at the top and a sixth tab L6 at the bottom. A seventh tab L7 is connected to the third wall W3 at the top and an eighth tab L8 at the bottom. A ninth tab L9 is connected to the first tab L1 at the top and a tenth tab L10 at the bottom.

[0031] The first wall W1 and the third wall W3 are separated by a first predetermined breaking line 1 of the predetermined breaking lines and, in extension thereto, by a first fold line F1 of the fold lines. The first flap L1 and the first wall W1 are separated by an eleventh predetermined breaking line 11 of the predetermined breaking lines and, in extension thereto, by a second fold line F2 of the fold lines.

[0032] The first wall W1 and the third flap L3 are separated by a third predetermined breaking line 3 of the predetermined breaking lines. A third fold line F3 of the fold lines separates the first wall W1 and the fourth flap L4.

[0033] The second wall W2 and the third wall W3 are separated by a fifth predetermined breaking line 5 of the predetermined breaking lines and, in extension thereof, by a fourth fold line F4 of the fold lines. The second flap L2 and the second wall W2 are separated by a sixth predetermined breaking line 6 of the predetermined breaking lines and, in extension thereof, by a fifth fold line F5 of the fold lines.

[0034] The second wall W2 and the fifth flap L5 are separated by a seventh predetermined breaking line 7 of the predetermined breaking lines. A sixth fold line F6 of the fold lines separates the second wall W2 and the sixth flap L6.

[0035] The seventh flap L7 is separated from the third wall W3 by a fold line (not designated in the figures), from the third flap L3 by a first cutting line S1 of the cutting lines and from the fifth flap L5 by a second cutting line S2 of the cutting lines.

[0036] The eighth flap L8 is separated from the third wall W3 by a fold line (not designated in the figures), from the fourth flap L4 by a third cutting line S3 of the cutting lines and from the sixth flap L6 by a fourth cutting line S4 of the cutting lines.

[0037] The ninth flap L9 is separated from the first flap L1 by a fold line (not designated in the figures) and from the third flap L3 by a fifth cutting line S5 of the cutting lines.

[0038] The tenth flap L10 is separated from the first flap L1 by a fold line (not designated in the figures) and from the fourth flap L4 by a sixth cutting line S6 of the cutting lines.

[0039] Furthermore, a fourth predetermined breaking line 4 of the predetermined breaking lines is provided in the first wall W1, parallel to and at a distance from the third fold line F3, and a fourth predetermined breaking line 4 of the predetermined breaking lines is provided in the second wall W2, parallel to and at a distance from the sixth fold line F6. A second predetermined breaking line 2 extends parallel to and at a distance from the eleventh predetermined breaking line 11 in the second wall 2 between the third predetermined breaking line 3 and the fourth predetermined breaking line 4.

[0040] The first, second, third, and fourth predetermined breaking lines 1, 2, 3, 4 delimit a first protective cover S1 formed by a portion of the first wall W1. And the fifth, sixth, seventh, and eighth predetermined breaking lines 5, 6, 7, 8 delimit a second protective cover S2 formed by a portion of the second wall W2.

[0041] To produce the first protective device according to the invention, the cardboard blank is made of Fig. 1 bent as follows:

[0042] The first flap L1 and the second flap L2 are folded backwards by 90° relative to the first wall W1 and the second wall, respectively, along the sixth predetermined breaking line 6 and the fifth fold line F5, and along the eleventh predetermined breaking line 11 and the second fold line, respectively. The second wall W2 is folded backwards by 90° relative to the third wall W3 along the fifth predetermined breaking line 5 and the fourth fold line, and the third wall W3 is folded backwards by 90° relative to the first wall W1, respectively, along the first predetermined breaking line 1 and the first fold line 1. This causes the first flap L1 and the second flap L2 to lie parallel and one above the other. The two flaps L1 and L2 are connected to one another, in particular glued, and together thus form a fourth wall W4.

[0043] The third flap L3, the seventh flap L7, the fifth flap L5, and the ninth flap are folded 90° around the third predetermined breaking line 3, the fold line between the seventh flap L3 and the third wall W3, the seventh predetermined breaking line, and the fold line between the ninth flap L9 and the first flap L1, respectively, so that they also overlap. The flaps are connected to each other, in particular glued, thus forming a fifth wall W5.

[0044] The fourth flap L4, the eighth flap L8, the sixth flap L6, and the tenth flap L10 are folded 90° around the third fold line F3, the fold line between the eighth flap L8 and the third wall W3, the sixth fold line F6, and the fold line between the tenth flap L10 and the first flap L1, respectively, so that they also overlap. The flaps are connected to each other, in particular glued, thus forming a sixth wall W6.

[0045] Fener, the first protective device has a tenth predetermined breaking line S10 in the first and second walls W1, W2. These delimit an area of the first wall W1 and the second wall W2. This delimited area can be separated from the first or second wall in order to mount a handle set or similar on the door otherwise protected by the protective device.

[0046] To mount a door leaf enclosed by the protective device on a frame, the protective covers S1, S2 can be separated from the other parts of the protective device and attached to the mounted door leaf to protect the closing side or opening side of the door leaf.

[0047] The second, in the Fig. 5 and Fig.The protective device shown in Figure 6 differs from the first protective device in that ninth predetermined breaking lines S9 or cutting lines 9 delimit an area in the third wall which can be cut out in order to mount hinges in the packaged door.
