Technical Field
[0001] The invention belongs to the field of door devices and, more specifically, concerns
a door stopper that can be used in several positions and locations, is small in size,
and portable.
Prior Art
[0002] There is a well-known door stopper, https://espak.ee/epood/toode/ukse-kiiltokis-35/,
which has a triangular cuboid made of rubber placed on the base. To keep the door
open, a door stopper is placed between the floor and the door. The disadvantage of
this solution is that the door stopper easily detaches and the door closes, and it
can only be used in one position and one location, between the door and the floor.
[0003] A door and window stopper is known (
EP 1 472 426 B1, Frank F. E. Mayer, published on July 26, 2006), which is a portable element cut out in an S-shape from elastic rubber to keep the
door or window open; it is placed between the floor and door or window and window
frame/window sill. The disadvantage of this solution is that it is quite large in
size and that it can easily move off from between the door or the window, and as a
result, it does not fulfill its original purpose.
[0004] A door stopper is known (
US11591836 B1, Scott W. Johnson, published February 28, 2023) and is configured so that the door is in a partially open position. The door stopper
comprises a fastener that is permanently attached to the door frame, plus a door bolt
and it's receiving element. To hold the door in the open position, the latch receiving
element engages the door latch and secures the door in a partially open position in
several aspects. The disadvantage of this solution is that the door stopper consists
of several assembly parts connected with screws and is permanently screwed to the
door jamb, and it can only be used in one position and in one location, between the
door and the door jamb.
[0005] A portable door stopper is known (
US2020208447 A1, Abraham Farkas, published on July 02, 2020), which holds the door in the open position. The portable door stopper consists of
one piece and comprises a body with a flat part and a bent part, with magnets in the
flat part and the bent part; and a secondary part. The disadvantage of this solution
is that the magnets are for additional fixing of the door stopper, which makes the
device difficult and expensive to manufacture, and the door stopper can only be used
in one position and one location, between the door and the door jamb.
[0006] The closest analog of the invention in terms of technical nature is a collapsible
door stopper (
CN217760535U, MA YEQIANG, published on November 08, 2022), which comprises a fastening element, a movable support, an extendable support leg,
a support element, a magnet, a height-adjusting element, and an anti-slip element.
The fastening element and the movable support are connected to each other by a joint.
The disadvantage of this solution is that it consists of several interconnected assembly
parts, where the fastening element comprises a magnet, which makes the device expensive
to manufacture, and this door stopper can only be used in one position and one location
- between the door and the floor.
Summary of the invention
[0007] The purpose of the invention is to develop a small-sized and portable door stopper
that can be used in several positions and locations.
[0008] The door stopper comprises a fastening element and a fixing element, which are connected
to each other with a joint. The fixing element is a cuboid, which can be moved to
the working or standby position with a joint. The fastening element is a special-shaped
cuboid with a projection on the upper face and a connecting element - double-sided
tape or glue or a screw - on the lower face. The fixing element includes a horizontal
cuboid and a vertical cuboid, which are connected to each other at an angle of 90
degrees. The fixing element comprises a channel where the sides of the channel have
top surfaces, and the wider side surfaces of the vertical cuboid are stopper surfaces.
The fixing element of the door stopper is at an angle to the fastening element, the
size of which depends on the place of use of the door stopper - the door stopper is
used either on the door, door jamb, or on the floor.

[0010] An example of the implementation of the invention
[0011] The door stopper of the invention comprises two elements: a permanently fixed fixing
element 1 and a movable fixing element 2, which are rotatably connected to each other
with a joint 3. The door stopper is designed to be attached to the door, door jamb,
or floor using the connecting element of the fastening element 1. The fixing element
2, which is intended to either prevent or release the movement of the door, allows
the door stopper to have two positions: the working position, where the door stopper
is intended to prevent the door from closing or opening too much, and the standby
position, where the door stopper does not prevent the door from closing.
[0012] The door stopper prevents self-closing doors from closing (e.g., when closing due
to a closing mechanism or as a result of a draft) or also limits the door from opening
too wide. It can be mounted on a door, door jamb, or floor, creating an obstacle between
the door and the door jamb or between the door and the floor. The door stopper is
attached to the floor, door, or door jamb by means of a connecting element.
[0013] The fastening element 1 is a triangular cuboid, the upper face of which comprises
a horizontal rectangular protrusion 1A in the middle part, and the lower face of which
accommodates a connection element (not shown in the figures), by means of which the
door stopper is attached to the door, door jamb or floor. The connecting element is
double-sided tape or glue or a screw passing through the fastening element 1. The
height of the fastening element 1 is lower than the gap between the door and the floor.
[0014] The fixing element 2 is a cuboid, which can be moved to the working and standby position
with joint 3. The fixing element 2 comprises a horizontal cuboid 2B and a vertical
cuboid 2C, which are connected to each other at an angle of 90 degrees, which makes
the fixing element 2 L-shaped. The wider side surfaces of the vertical cuboid 2C are
stopper surfaces 2D and 2E. The horizontal cuboid 2B contains a channel 2A, the sides
of which are formed by the top surfaces 2F. At the lower end of the vertical cuboid
2C is a partial indentation 2G.
[0015] Fixing element 2 is used in two positions:
- the fixing element 2 is in the closed position - the fixing element is folded (the
fixing element "sits" on the fastening element) in such a way that the stopper surface
2D of the fixing element forms an angle of approximately 100-135 degrees with respect
to the rectangular projection 1A of the upper face of the fastening 1;
- the fixing element 2 is in the open position - the fixing element 1 and the fixing
element 2 are substantially aligned with each other (horizontally extended) and form
an angle of approximately 135-180 degrees.
[0016] The joint 3 is at the distal end of the fastening element 1 of the rectangular projection
1A of the fastening element 1 and at the end (which is convex in the preferred embodiment)
of the horizontal cuboid 2B of the fixing element 1, which is not connected to the
vertical cuboid 2C.
[0017] At the lower end of the vertical cuboid 2C, there is a partial indentation 2G, which
allows the fixing element 2 to "sit" on the fastening element 1 in such a way that
the surfaces 2F are in full contact with the upper face of the fastening element 1.
[0018] The size of the angle formed between the fastening element 1 and the fastening element
2 depends on where the door stopper is placed - between the door and the floor or
between the door and the door jamb.
[0019] The height of the vertical cuboid 2C of fixing element 2 is chosen in such a way
that the door stopper does not prevent the door from closing in the standby position
when used on the floor and prevents the door from closing in the working position.
[0020] By moving the fixing element 2 with the help of joint 3, the door stopper can be
moved to different positions. When the fixing element 2 is folded using joint 3, the
cuboid projection 1A of the fixing element 1 enters the channel 2A and the indentation
2G of the fixing element 2, and the fixing element 2 "sits" fixedly with the upper
surfaces 2F on the fixing element 1.
[0021] If you install the door stopper on the floor, the door stopper limits the opening
of the door away from the doorway or the closing of the door in the direction of the
doorway.
[0022] If the door stopper is used on the floor and the door stopper is in the open position
(in a horizontal position, at approximately 160-180 degrees, in an extended position),
the door moves freely over the door stopper, and the door can be opened or closed
(the door stopper is in the standby position).
[0023] If the door stopper is used on the floor and the door stopper is in the folded position,
the door does not move freely (the door stopper is in the working position). Fixing
element 2 is in the raised, folded position. If the door is open and the door stopper
is in the part between the door and the doorway, the stopper surface 2E or 2D of the
door stopper prevents the door from closing (depending on which direction the door
stopper is attached to the floor). The door stopper is also used on the floor to prevent
the door from opening too much (e.g., the door does not hit the wall when it opens
too much). If the door is open and the door stopper is behind the door (not in the
part between the door and the doorway), then the stopper surface 2E or 2D of the door
stop prevents the door from opening too far (depending on which direction the door
stopper is attached to the floor).
[0024] If the door stopper is used on a door or door jamb and the door stopper is in the
open position, the door does not move freely (the door stopper is in the working position).
The door stopper fastening element 1 is attached to the side of the door or to the
door jamb in such a way that the upper surfaces 2F of the horizontal cuboid 2B of
the door stopper create an obstacle between the door and the door jamb when the door
closes, which prevents the door from closing completely. If the door stopper is used
on a door or door jamb and the door stopper is in the folded position, the door closes
freely (the door stopper is in the standby position).
[0025] The peculiarity of the door stopper is that its position can be changed as needed.
When installed on the floor, the position of the door stopper can be changed in such
a way that it restricts the movement of the door in the folded, i.e., working position
(the fixing element 2 "sits" on the fixing element 1 and creates resistance between
the door and the floor) and allows the door to move freely over itself in the open
or standby position (the fixing element 2 and the fixing element 1 are away from each
other in a horizontally spaced position). When installed on a door or door jamb, the
position of the door stopper can be changed in such a way that it allows the door
to close freely in the folded or standby position and restricts the closing (movement)
of the door in the open or working position, when it creates an obstacle between the
door and the door jamb.
[0026] The door stopper is easy to install. The door stopper is portable, and the user can
carry the door stopper with him/her and optionally use it if he/she wants.
[0027] The door stopper is useful:
- for temporarily leaving the self-closing door open;
- when keeping the door open, if the door suddenly closes (e.g., as a result of a draft);
- when limiting the opening trajectory of the door (e.g., to prevent the door from "breaking"
if it opens excessively);
- when opening the door to prevent damage to the surface behind the door (e.g., wall
or cabinet) with the door if there is a physical obstacle behind the door when it
opens too wide.
