Abstract

A device for retaining a door or the like in an open position comprises a rotatable member (2), in bearings (4,5) provided in an aperture formed in the door. One end of the rotatable member has an actuating device (1) associated therewith and the other end thereof is in the form of a clasp (7) or hook member. The actuating device (1) is rotatable between two end positions. In one position, the rotatable member (2) permits opening and closing of the door and, in the fully open position of the door, strikes against a cushion portion (9) of a pin (8) located on the floor and acting as a limit stop. In such fully-open state, the actuating device (1) can be rotated into its other end position whereupon the clasp or hook member (7) engages the surface of the cushion member (9) remote from the door and the door is thus prevented from closing until the actuating means (1) is returned to its original position (A). <IMAGE>

Description

SPECIFICATION An apparatus for retaining a door in an open position The present invention relates to a device for retaining a door, a gate or the like in an open position.

A known device for retaining a door in an open position comprises a ring member which is fastened to the lower edge region of the door. This ring is, in use, located around a pin located in a suitable position on the floor of a room orthe stairs, thereby keeping the door in an open position. To close the door the ring must be removed from the pin. This can be particularly difficult to achieve for elderly or infirm people. In fact, if the pin is located in a narrow space between the open door and for example the wall of a room as is often the case the removal of the ring from the pin is not easy, even for an able-bodied person. Another known device, in the form of a window bolt is disclosed in DE-patent publication No. 565,586, wherein a limit device is provided for preventing the window from being opened too wide.

This device is, however, designed to be fixed onto a wall, which restricts its field of application.

The present invention seeks to provide a device which eliminates or at least minimises the disadvantges of such known device and to facilitate the retaining of a door in an open position and the subsequent unfastening and closing of the door.

According to the present invention, there is provided a device for retaining a door or the like in an open position comprising a rotatable member mounted in bearings and which passes, in use, through an aperture formed in the door, the rotat able member having a first end portion upon which actuating means are formed or provided and a second end portion in the form of a clasp or hook member, the two end portions, in use, projecting from opposite faces of the door, the hook member or clasp engageable behind a pin member mountable on a floor or the like, the pin member including a cushion portion, the rotatable member being rotat able between two end portions, one end position being that in which the clasp or hook portion thereof engages the surface of the pin member remote from the door to prevent the door from closing and the second end position being that in which the door is free to close.

One embodiment of the present invention will be further described, by way of example, with reference to the accompanying drawings, in which: Figure 1 shows a front view of one lower corner region of one of the major faces of a door having a device in accordance with the present invention fitted thereto; Figure 2 shows a side view of the corner region of the door and of the device shown in Figure 1; and Figure 3 shows a view similar to Figure 1 but of the other major face of the door.

In Figure 1 there is shown a control wheel 1 which is located on one major face of a door B. The wheel is mounted to a shaft 2 which passes through the door B as shown in Figure 2. The wheel 1 and shaft 2 can be rotated through substantially 90" between two operative positions A and K. Known locking means 3 fitted provided internally of the wheel 1 cause the wheel and shaft to remain in the desired position A or K. The shaft 2 is mounted in bearings in the door B by means of bearing plates 4 and 5. On one side of the door a counter plate 6 for the bearing plate 5 is mounted on the shaft 2. One end of the shaft is bent over to form a clasp or hook-like member 7. A pin or the like 8 is attached to the floor Cat a suitable location, the upper end having a cushion member 9 preferably made of rubber or a similar resilient material - mounted or formed thereon.The pin 7 is so located that, in use, the pin 7 is located between the clasp or hook member 7 and the door B. When the wheel 1 is in position A, the clasp or hook member 7 located at the other end of the shaft 2 on the opposed face of the door extends downwards in position A1 as shown in Figure 3. The door can thus be freely moved in its open position until the member 7 strikes against the rubber cushion 9 of the fastening pin 8, the cushion 9 thus acting as a limiting stop. If the door is to be secured in the open position, the wheel 1 is rotated into position K. This rotates the shaft 2 and the clasp or hook member 7 into position K - see Figure 3 - and the door is caused to remain open because the member 7 is located behind the cushion 9. This locking can be removed by rotating wheel 1 back into position A.

The wheel 1 is designed to be rotated by the foot of a user. Accordingly, the user does not need to bend down or take any unnecessary trouble in order to lock the door in the open position or to unlock the door from the open position. Moreover, the fastening pin 8 does not penetrate rubber cushion 9 thereby reducing the danger inherent in known pins, the ends of which penetrate the cushion.

The device is particularly suitable for use in those environments in which the space between an open door and a wall adjacent thereto or other type of barrier, is relatively inaccessible.
