Description

[0001] The present invention relates to a door according to the preamble of claim 1.

[0002] Doors with a finger protection element are known from the state of the art.

[0003] WO 2019 / 038030 A1 discloses a finger protection device for bridging a gap in a door that can be closed by a door leaf. It comprises a winding shaft with a first end and a second end, and a roller blind that can be wound around the winding shaft by means of the winding shaft. End caps are provided above and below the winding shaft.

[0004] GB 2 164 690 A discloses a door safety device consisting of a flexible film wound on a roll within a tube having a longitudinal slot from which the film protrudes. The device is mounted adjacent to a hinge opening so that when the door is opened, the film extends over the opening and is retracted from the slot against a spring bias to protect the opening and thus prevent fingers from becoming trapped.

[0005] In contrast, the present invention is based on the object of creating a door that is better adapted to local conditions.

[0006] This object is achieved by a door according to claim 1, a system according to claim 12 and a method according to claim 14.

[0007] The door comprises a door leaf, a door frame, a finger protection element, and an extension element. The finger protection element can, for example, comprise a profile or be designed as a profile. A roller blind, for example, can be arranged on the finger protection element, preferably on the profile, which covers a gap between the door leaf and the door frame when the door leaf is open. The extension element can, in particular, be a separate component from the finger protection element. The extension element can, for example, be attached to the finger protection element.

[0008] The door leaf is pivotally mounted on the door frame. By pivoting the door leaf, the door leaf can be moved from an open state to a closed state and vice versa. For the purposes of this description, the open state is understood in particular to mean that an opening surrounded by the door frame is exposed, allowing a person to pass through. For the purposes of this description, the closed state is understood in particular to mean that the door leaf closes this opening.

[0009] The finger protection element is attached to the door leaf. At least a portion of the extension means is arranged below a lower end of the finger protection element. Preferably, the extension means can be attached to the lower end of the finger protection element. For example, the extension element, with the exception of the portion, can protrude into the finger protection element and be attached to the finger protection element with the area protruding into the finger protection element.

[0010] The section of the extension element has a smaller cross-sectional area than the finger protection element. In particular, it is possible for the entire section to have a smaller cross-sectional area than the finger protection element.

[0011] The section with the smaller cross-sectional area below the finger protection element is advantageous if there is an obstacle in the area of ​​the door, for example a tile or a skirting board, against which the finger protection element would strike when the door leaf is opened if it were mounted at the height of the obstacle. It is advantageous to arrange the finger protection element above the obstacle to enable the door leaf to be opened as intended. For aesthetic reasons and to protect against pinching, it is advantageous to arrange the extension element at the height of the obstacle. However, this is only possible without impairing the functionality of the door if it does not strike the obstacle when the door leaf is opened. For this reason, the smaller cross-sectional area, in particular the recess, is advantageous. Preferably, the cross-sectional area of ​​the section is adapted to the obstacle. The section has the recess for this purpose.

[0012] With the exception of the recess, the extension element can be rotationally symmetrical. This is advantageous for allowing the extension element to be used in a similar or identical manner, for example, above the finger protection element.

[0013] According to one embodiment of the invention, the extension means can have a plurality of guide elements. The guide elements can each be designed to guide a cutting tool in a guide direction when severing the extension means. In this way, the extension means can be particularly easily adapted to local conditions, for example, to an obstacle. The guide elements can also be referred to, for example, as notch options. In this case, a recess in the extension means adapted to the obstacle can also be referred to as a notch.

[0014] According to one embodiment of the invention, the guide direction can run horizontally and parallel to a surface of the door leaf. The finger protection element can rest against the surface. This guide direction is advantageous for creating a recess in the extension element that is adapted to a tile or baseboard.

[0015] According to one embodiment of the invention, the guide elements can form a corrugated surface of the extension means. In the context of this description, the corrugated surface is understood in particular to mean alternating projections and depressions. The corrugated shape is particularly advantageous for arranging a relatively large number of guide elements close to one another.

[0016] According to one embodiment of the invention, the finger protection element can comprise a profile attached to the door leaf and a roller blind attached to the profile. The roller blind can, for example, be able to be rolled up onto and off a winding shaft attached to the door frame.

[0017] According to one embodiment of the invention, the finger protection element can be designed as a finger guard for a secondary closing edge of the door leaf. In this case, finger guard is understood in particular to mean preventing a human finger from becoming trapped between the secondary closing edge and the door frame. In the context of this description, the secondary closing edge is understood in particular to mean the edge whose extension in the vertical direction is greatest and which moves less far than the opposite edge during the opening and closing process of the door leaf.

[0018] According to one embodiment of the invention, the extension means can be attached, in particular directly, to the finger protection element.

[0019] According to one embodiment of the invention, the extension means can be attached to the finger protection element by means of screws.

[0020] According to one embodiment of the invention, the extension means can be inserted into the finger protection element.

[0021] According to one embodiment of the invention, the extension means can be attached to the door leaf or the finger protection element via an adhesive connection. This is particularly advantageous if, for example, in the case of a glass door, damage to the door leaf is to be avoided.

[0022] According to one embodiment of the invention, the door may comprise a further extension means, a portion of which is arranged above an upper end of the finger protection element. The further extension means may have some or all of the features of the previously described extension means. The use of the further extension means may be advantageous, particularly for aesthetic reasons. Furthermore, it may be advantageous if there is a further obstacle in the upper region of the door leaf that prevents the door leaf from opening if the finger protection element extends into this region.

[0023] The system according to claim 12 comprises a door according to one embodiment of the invention, a wall, and an obstacle arranged on and protruding from the wall. The obstacle can be, for example, a baseboard or a tile. The door frame is attached to the wall. The extension means has a recess. When the door leaf is open, the obstacle is arranged in the recess. Preferably, the shape of the recess can be adapted to the shape of the obstacle.

[0024] According to one embodiment of the invention, the obstacle can be superimposed with a virtual extension of the finger protection element beyond the lower end of the finger protection element when the door leaf is in the open state. In this description, the virtual extension is understood in particular to mean an extension that is not present as a component, but merely an imaginary extension. The shape of the finger protection element is continued in the extension. Due to the superimposition of this virtual extension on the obstacle, it would be impossible to bring the door leaf into the open state if the finger protection element were arranged within the area of ​​the extension. In such situations, the use of the extension means with the recess is particularly advantageous to ensure that the door leaf can be opened.

[0025] In the method according to claim 14, the door leaf, the door frame, the finger protection element, and the extension means are provided. The extension means can be designed to be rotationally symmetrical. The finger protection element is attached to the door leaf. The recess is formed in the extension means. Guide elements can preferably be used for this purpose. The extension means is attached to the finger protection element or to the door leaf. The extension means is preferably arranged below the lower end of the finger protection element.

[0026] It is possible that one, some or all of the components used in the method may have one, some or all of the features from the previous description of the door or system.

[0027] According to one embodiment of the invention, the dimensions and position of the recess can be adapted to the dimensions and position of the obstacle.

[0028] Further features and advantages of embodiments of the invention are described below with reference to the drawings. The same reference numerals are used for identical or similar parts and for parts with identical or similar functions. They show: Fig. 1 A-B schematic perspective views of an extension means according to an embodiment of the invention; Fig. 2 A-B schematic perspective views of an extension means arranged at one end of the finger protection element from Fig. 1; Fig. 3 A-B schematic perspective views of two extension means arranged at both ends of the finger protection element; Fig. 4 a schematic perspective view of an extension means fastened to a door leaf with an adhesive connection; Fig. 5 a schematic perspective view of an extension means fastened to a door leaf with an adhesive connection; Fig. 6 a schematic plan view of an extension means according to an embodiment of the invention; and Fig. 7 A-H various schematic views of differently designed extension means and finger protection elements.

[0029] It is not necessary for a device according to the invention to have all of the features described below. It is also possible for a device according to the invention to have only individual features of the exemplary embodiments described below.

[0030] The extension means 100 has a section 101 in which a recess 102 is provided. When arranged on the finger protection element 200, the section 101 protrudes from the finger protection element 200. Furthermore, the extension means 100 comprises a region 103 in which holes 104 are arranged.

[0031] The extension means 100 is inserted with the region 103 into the finger protection element 200, so that the section 101 is arranged below the lower end of the finger protection element 200. In many of the figures, the extension means 100 is arranged above the finger protection element 200. However, this does not necessarily correspond to the orientation during installation on a door leaf 400.

[0032] The extension means 100 is fastened to the finger protection element 200 with screws 300 by passing the screws 300 both through the finger protection element 200 and through the holes 104 in the area 103 of the extension means 100.

[0033] Since the recess 102 is arranged in section 101, it is located below the finger protection element 200. The size and position of the recess 102 are adapted to the size and position of an obstacle on a wall. The obstacle is arranged such that if the finger protection element 200 were positioned up to the lower end of the door leaf 400, the finger protection element 200 would strike the obstacle when the door leaf 400 is to be opened, thus preventing the door leaf 400 from opening. For this reason, it is advantageous to arrange the extension means 100 below the finger protection element 200 and to adapt the recess 102 to the size and position of the obstacle.

[0034] However, as in the Figures 3A and 3Bshown, two extension means 100 are provided, one of which is arranged above the upper end of the finger protection element 200 and one below the lower end of the finger protection element 200.

[0035] The extension means 100 is rotationally symmetrical before the recess 102 is formed. This is advantageous for enabling the extension means 100 to be used in a particularly diverse manner, for example, for use as an extension means 100 above the upper end of the finger protection element 200.

[0036] In the Figures 4 and 5 It is shown how the extension means 100 is attached to the finger protection element 200 via an adhesive connection. This can be advantageous, for example, if the door leaf 400 is made of a fragile material such as glass and could be damaged by the screws 300.

[0037] In Figure 6It is shown that the extension means 100 has a plurality of guide elements that together form a corrugated shape 600. The guide elements are designed to guide a cutting tool in a guide direction. The corrugated shape 600 is arranged on the end surfaces of the extension means 100, which, when the extension means 100 is attached to the finger protection element 200, delimit the extension means 100 in the horizontal direction. This facilitates the introduction of the recess 102 into the extension means 100.

[0038] In the Figures 7A to 7HIt is illustrated how differently the finger protection element 200 and the extension means 100 can be designed. Both the thickness of the finger protection element 200 and the length of the area 103 inserted into the finger protection element 200 can vary greatly. The principle of the invention, that an obstacle protruding from the wall does not hinder the opening of the door leaf 400 due to a corresponding recess 102 in the section 101, remains the same.
