Abstract

The present disclosure relates to a door leaf formed of a flexible material, wherein the flexible material is resistant to puncture and resistant to tearing; and to a door system comprising the door leaf.

Claims (33)

1 . A door system comprising:

a door leaf,

an attachment member comprising a top end and a bottom end, and

an attachment assembly,

wherein the attachment assembly rotationally couples the door leaf to the attachment member and is configured to restrict rotation of the door leaf relative to the attachment member to no more than 180 degrees;

wherein the attachment assembly comprises:

a hinge pin,

a top end-cap attached to the top end of the attachment member,

the top end-cap presenting a first side, a second side, a top surface disposed between the first side and the second side, and a bottom surface opposite the top surface,

wherein a top end of the hinge pin is received within the bottom surface of the top end-cap to thereby rotationally couple the door leaf to the attachment member, and

wherein the top end-cap has the top surface sloped outwardly at an angle and downwardly relative to a vertical axis of the hinge pin such that the top end-cap does not present a ligature point, thereby preventing an object from being anchored to the top end-cap.

2 . The door system of claim 1 ,

wherein the attachment assembly further comprises a bottom end-cap attached to the bottom end of the attachment member,

wherein a bottom end of the hinge pin is received within the bottom end-cap, and

wherein the top end-cap and the bottom end-cap are identical to one another.

3 . The door system of claim 1 , wherein the door leaf comprises a channel extending along an edge thereof, wherein the channel receives the hinge pin.

4 . The door system of claim 3 , further comprises a bottom end-cap, wherein at least one of the top end-cap or the bottom end-cap abuts a respective end of the channel.

5 . The door system of claim 4 , wherein the attachment member comprises a recess configured to receive the channel.

6 . The door system of claim 5 , wherein an outer diameter of the channel is equal to an inner width of the recess.

7 . The door system of claim 1 , further comprising a bottom end-cap, wherein one of the top end-cap or the bottom end-cap and the hinge pin comprises at least one detent arranged to restrict a rotation of the hinge pin relative to the attachment member.

8 . The door system of claim 1 , wherein a top edge of the door leaf forms an acute angle with respect to the attachment member.

9 . The door system of claim 1 , wherein at least one corner of the door leaf is rounded.

10 . The door system of claim 1 , wherein the door leaf is bendable.

11 . The door system of claim 1 , wherein the attachment assembly is configured to restrict rotation of the door leaf relative to the attachment member to less than 150 degrees.

12 . The door system of claim 1 , further comprising a fixing member comprising opposing jaws defining a recess therebetween, the fixing member configured for attachment between the attachment member and a wall or a door frame.

13 . The door system of claim 12 , further comprising a bottom end-cap, wherein at least one of the top end-cap or the bottom end-cap comprises fixing points for attachment to the fixing member.

14 . The door system of claim 1 , wherein the vertical axis is a central vertical axis.

15 . The door system of claim 3 , wherein the channel comprises a core layer sandwiched between a first skin layer and a second skin layer.

16 . The door system of claim 15 , wherein the core layer comprises an aramid fibre and the first skin layer and the second skin layer comprise plasticized PVC-coated woven nylon fabric.

17 . The door system of claim 15 , wherein the channel comprises a hollow aluminium tube.

18 . The door system of claim 15 , wherein an interface between the channel and the core layer is rounded.

19 . The door system of claim 7 , wherein the hinge pin comprises a protrusion configured to engage the at least one detent, thereby limiting the rotation of the hinge pin.

20 . The door system of claim 19 , wherein the at least one detent comprises a first detent and a second detent arranged on opposing sides of the top end-cap or the bottom end-cap.
