This disclosure relates to an apparatus for preventing a structure from completely or substantially closing flush against a frame.
Various apparatus are used to prevent doors (or other entry/exit structures, such as, for example, gates, panels, or other structures) from contacting other objects. For example, a stop is a device that can be used to hold a door open or closed in order to prevent a door from contacting another object or from opening too widely. In some instances, a stop can prevent the door from coming into contact with a wall surface on which the doorframe is mounted. In other examples, a stop can be a movable device that is disposed on a floor and adjacent the surface of a doorframe in order to prevent a hinged door or a sliding door from closing securely within a doorframe. In some examples, a movable door stop can also be disposed on a floor in proximity to a doorway and seated beneath the surface of a hinged door such that the door is prevented from closing beyond the position of the stop. While such movable stops can prevent accidents in some examples, movable stops can sometimes become displaced from their intended positions and thus fail to prevent a door from closing completely on an object within a doorframe.
In one general embodiment, a device includes a base attachable to a first side of a door; a swing arm coupled to the base, the swing arm including a bracket flange configured to extend across an edge of the door between the first side of the door and a second side of the door opposite the first side of the door; and a biasing member coupled between the swing arm and the base and configured to urge the swing arm from a retracted position in which the bracket flange is adjacent the edge to an extended position in which the bracket flange is apart from the edge.
In another general embodiment, a method includes attaching a base of a blocking device to a first side of a door; urging a swing arm including a bracket flange, and coupled to the base, towards an edge of the door extending between the first side of the door and a second side of the door opposite the first side of the door; closing the door substantially flush against a doorframe such that the bracket flange is positioned between the edge of the door and the doorframe; and opening the door such that the swing arm is urged away from the edge of the door by a biasing member coupled between the swing arm and the base.

Various embodiments of a device for blocking closure of a door or other moveable structure according to the present disclosure may include one or more of the following features. For example, the device can include a base that is attachable to a first side of a door and a swing arm that is coupled to the base. In some examples, the swing arm includes a stop and a bracket flange that can extend across an edge of the door from the first side of the door to a second side of the door. In some instances, the device further includes a biasing member that couples the swing arm to the base and which can be housed within the base.
Various embodiments of a device according to the present disclosure may also include one or more of the following features. For example, the biasing member can be configured to urge the swing arm away from the base, such that the swing arm is disposed in an extended position and the stop can prevent the door from closing completely within a doorframe. In some examples, the bracket flange can be urged flush against the edge of the door, such that the biasing member extends and thereby disposes the swing arm in a retracted position.
Various embodiments of a device according to the present disclosure may also include one or more of the following features. In some embodiments, the device may be configured for use with one or more door configurations including a left hand hinge door having a normal swing direction, a left hand hinge door having a reverse swing direction, a right hand hinge door having a normal swing direction, and a right hand hinge door having a reverse swing direction.
Various embodiments of a device according to the present disclosure may also include one or more of the following advantages. In some examples, the device can act as a safety mechanism by preventing a door from smashing a small object, such as a finger or a child's hand, between a door and a doorframe. By positioning the device at a sufficient height along the door, a small child can further be prevented from having access to the device and thus from adapting the device from an extended configuration to a retracted configuration and vice versa. In some instances, the device can be used to maintain a door ajar from a doorframe, irrespective of associated safety aspects of the device. In some cases, the attachable feature of the device can remove the need to check the positioning of the device and the need to reposition the device, in contrast to movable, floor-seated devices that can easily be displaced from their intended positions and thus may require repositioning.
These general and specific aspects may be implemented using a device, system or method, or any combinations of devices, systems, or methods. The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features, objects, and advantages will be apparent from the description, the drawings, and the claims.
This disclosure relates to an apparatus for preventing an entry/exit structure from completely or substantially closing flush against a frame, and more particularly, to a door block used for preventing a door from smashing an object, such as a finger, between a door and a doorframe as the door closes toward the doorframe. In a general embodiment, a device for blocking closure of a door or other moveable structure includes a base that is attachable to a first side of a door and a swing arm that is coupled to the base. In some examples, the swing arm includes a bracket flange that can extend across an edge of the door from the first side of the door to a second side of the door. The swing arm can further include a stop that may prevent the door from closing completely within the doorframe.
In some embodiments, the device further includes a biasing member that couples the swing arm to the base. In some examples, the biasing member can be housed within the base. In some examples, the biasing member can be configured to urge the swing arm away from the base, such that the swing arm is disposed in an extended position and the stop can prevent the door from completely or substantially closing within the doorframe, thereby further preventing the door from smashing an object, such as a finger, on a doorframe. In some examples, the bracket flange can be urged against the edge of the door, such that the biasing member extends and thereby disposes the swing arm in a retracted position. In some embodiments, the base can include a cutout having the shape of the stop and accommodating the stop when the swing arm is disposed in a retracted position. In a retracted configuration, the device can allow the door to close completely within a surrounding doorframe.
In some embodiments, the device can include one or more pull handles coupled to the stop and/or the bracket flange for urging the swing arm towards the base. In some embodiments, the device can be configured for use with one or more door configurations including a left hand hinge door having a normal swing direction, a left hand hinge door having a reverse swing direction, a right hand hinge door having a normal swing direction, and a right hand hinge door having a reverse swing direction.
In some examples, the door block can act as a safety mechanism by preventing a door from smashing a small object, such as a finger or a child's hand, between the door and the doorframe. By attaching the device to the door at a sufficient height, a small child can further be prevented from having access to the device. In some examples, the device can be used to maintain the door ajar from the doorframe. In some cases, an attachable feature of the device can remove the need to check the positioning of the device and the need to reposition the device.

Referring again to
In some embodiments, a door block can be configured as a mirror image of the door block 100, such that the door block is configured for use with a right hand hinge door having a normal swing direction and a left hand hinge door having a reverse swing direction. Alternatively, the door block 100 may be mounted on either of a left hand hinged door or a right hand hinged door by, for example, inverting the door block 100 and attaching the door block 100 upside down on the door.
In some examples, a door block (e.g., the door block 100) can act as a safety mechanism by preventing a door from smashing a small object, such as a finger or a child's hand, between a door and a doorframe. By positioning the door block at a sufficient height along a door, a small child can further be prevented from having access to the door block and thus from adapting the door block from an extended configuration to a refracted configuration and vice versa. In some examples, the door block can be used to maintain a door ajar from a doorframe, irrespective of associated safety aspects of the door block. In some examples, the attachable feature of the door block can remove the need to check the positioning of the door block and the need to reposition the door block, in contrast to movable, floor-seated stops that can easily be displaced from their intended positions and thus may require repositioning.
A number of embodiments have been described. Nevertheless, it will be understood that various modifications may be made. For example, although a coil spring is shown in the illustrated embodiments, other types of biasing members (e.g., elastic bands) may be used in place of the coil spring. Furthermore, various combinations of the components described herein may be provided for embodiments of a similar apparatus. Accordingly, other embodiments are within the scope of the present disclosure.
