Description

DOOR STOPPER TECHNICAL FIELD OF THE INVENTION

The invention relates to a door stopper according to claim 1.

BACKGROUND OF THE INVENTION

There are available different door stopper solutions available for keeping doors temporarily in an opened position. These include commonly used wedges, often made of wood or elastic material such as rubber, that are wedged below a door leaf in order to keep the door leaf in a certain opened position. There are also available door stoppers that can be attached to the upper side of a door leaf in order to lock 10 it into a certain position.

A disadvantage of the mentioned door stoppers is that they are situated either below the door leaf or above the door leaf. Therefore a person wanting to place the door stopper in order to keep the door open either needs to bend down to place the door stopper or to reach out high to the top of the door in order to place it.

It is objective of the invention to provide an alternative door stopper that provides improved ergonomics for the person wanting to use it.

SUMMARY OF THE DISCLOSED SOLUTION

This objective is achieved with a door stopper according to claim 1.

According to the invention the door stopper comprises a wedge element, the wedge 20 element having a first surface and a second surface arranged in parallel with the first surface, the surfaces facing opposite directions, wherein each of the first surface and the second surface have a height and a width. The second surface is configured to be engaged with the frame of a door or a hinge of a door, and at least one side surface connects the first and the second surface. The at least one side surface 25 is configured to engage at least with a door leaf, the distance between the first and the second surface is smaller than the smallest dimension of the heights and widths of the first and the second surface. The second surface is equipped with a magnet

20185540 prh 15 -06- 2018 such that the door stopper is attachable to a metal door frame or to a metal hinge of a door.

According to the invention the distance between the first and the second surface is smaller than the smallest dimension of the heights and the widths of the first and the 5 second surface. In case the first and the second surface have a rectangular, polyangular or square surface, the heights and the widths are the heights and the widths of the surfaces in question. In case the first and the second surface have a circular shape, the heights of the surfaces correspond to the diameters, as the widths equally correspond to the diameters. In case of circular first and second sur10 faces, the distance between the first and the second surface is thus smaller than the diameters of said surfaces.

Some kind of door frames have on their inner sides additional vertical inwardly protruding portions. When used with this kind of door frames, a door stopper according to the invention often abuts with one side surface against this protruding portion 15 while it abuts against the door leaf on the opposite side.

A door stopper according to the invention is configured such that it can be placed between a door frame or a door leaf at a position convenient for the person wanting to place the door stopper. As the second surface of the door stopper is equipped with a magnet, the door stopper can be removably attached to a metal part of the 20 door frame or for example a hinge. In case of a metal door, the door stopper can be attached to the door frame at any height in convenient reach for a person. In case of a non-metal door, the door stopper according to the invention can be attached to a metal hinge, which are usually situated in the middle of the door, approximately 20-30 cm below the upper edge of the door and approximately 20-30 cm upwards 25 from the bottom edge of the door. A door stopper according to the invention can thus be placed more ergonomically and conveniently compared to wedges of the state of the art.

According to one embodiment the magnet is embedded in the second surface or glued to the second surface. The embedded magnet can be attached to the second 30 surface for example with a common glue or can be attached to the wedge element during molding of the wedge element. The strength and the dimensions of the

20185540 prh 15 -06- 2018 magnet have been selected such that the wedge element attaches to a metal door frame or hinge but the wedge element is removable from the door frame or the hinge with little force.

According to another embodiment the first and the second surface of the wedge 5 element are of equal size and shape.

The size of the surfaces of the wedge shaped element is chosen according to the space present between an opened door leaf and a vertical protruding portion on one of the vertical inner sides of a door frame, such that the door stopper can be wedged into that space such that the second surface of the wedge shaped element of the 10 door stopper abuts with part of the door frame or a hinge of the door, while at least one side surface of the wedge shaped element abuts against the door leaf.

According to one embodiment the door stopper has rounded edges. This shape is preferable, as a rounded shaped wedge element is more easy to install in the space between the opened door leaf and the door frame. Also, when the wedge element 15 has a shape with rounded edges or no edges, damage to the door leaf or door frame is prevented.

According to one embodiment the shape of the first and second surface is round.

When the first and the second surface have a round shape, the diameter of the diskshaped wedge element is preferably 50-120 mm.

According to one embodiment the diameter of the first and the second surface of the wedge element is 60-110 mm.

According to another embodiment the wedge element is made of essentially elastic material. The disk-shaped wedge element is preferably made of wood, laminated wood, composite, plastic or rubber. An elastic material of the wedge element is ad25 vantageous for a door stopper, as a door stopper of elastic material can more easily be wedged between a door frame and a door leaf. Elastic material also prevents damaging of material or paint of the door frame and the door leaf.

20185540 prh 15 -06- 2018

According to another embodiment a gripping element has been attached to the first surface of the wedge element which gripping element protrudes outwardly from the first surface.

By using the gripping element, a person can grip the door stopper and place it to the 5 wedging position between a door frame and a door leaf.

According to one embodiment a connection line such as a chain, a wire or a rope is attached to the wedge element connecting the door stopper to an attachment piece attached to a wall or door frame.

This connection line can be attached to the wedge for example by means of a screw connection. The attachment piece is preferably a screw or bolt attached to the door frame or to a wall in vicinity of the door frame. The length of the connection line is slightly larger than the distance between the attachment place and an intended wedging place for the door stopper such that the door stopper is convenient to install. The length of the connection line is however shorter than the distance from the attachment place to the ground, in order to prevent dropping of the wedge element to the ground.

Additionally, a holder for the wedge element can be fixed for example to the wall next to the attachment place. When not in use for wedging the door, the door stopper can be stored in this holder.
