Abstract

A door handle (1) is adapted to apply liquid or gel (liquid/gel) to a user'"'"'s hand. The handle (1) comprises a handle grip (2) and a liquid/gel reservoir (6) associated with the handle (1). A liquid/gel displacement device is arranged in the grip (2) and a non-return valve (53) is provided to allow liquid/gel to flow from the reservoir (6) to the displacement device. A hollow trigger (8) is displaceably mounted on the grip (2) and adapted to actuate the displacement device when the handle (1) is gripped for displacement of liquid/gel from the displacement device, into the trigger (8) and then on to a hand or its digits gripping the trigger (8).

Claims

1. A door handle adapted to apply liquid or gel (liquid/gel) to a user'"'"'s hand, the handle comprising:

a handle grip;

a liquid/gel reservoir associated with the handle;

a liquid/gel displacement device in the grip; and

a hollow trigger displaceably mounted on the grip and adapted to actuate the displacement device when the handle is gripped for displacement of liquid/gel from the device, into the trigger and thence on to a hand or its digits gripping the trigger;

wherein the trigger is provided with a plurality of liquid/gel outlets which are normally closed and are individually opened by digital pressure on them, whereby the liquid or gel is expelled selectively where the digits act against the trigger.

2. The door handle of claim 1, wherein the reservoir is above the grip with gravity assisting or causing the liquid/gel to flow down.

3. The door handle of claim 1, wherein individual closure members, such as balls, are provided to close individual outlets, with each closure member being urged into its outlet by a respective spring.

4. The door handle of claim 3, wherein the springs are coil springs or leaf springs in the form of tabs bent from a single strip.

5. The door handle of claim 1, wherein closure members are provided to close individual outlets, the closure members being integrally moulded to resilient fingers, which urge their closure members into the outlets.

6. The door handle of claim 1, comprising a non-return valve allowing liquid/gel flow to from the reservoir to the displacement device.

7. The door handle of claim 1, comprising a second grip adapted to provide a physical antibacterial action.

8. The door handle of claim 1, comprising a guard member arranged to protect the reservoir from impact, if a door on which the handle is adapted to be mounted is opened and brought into contact with an adjacent wall.

9. The door handle of claim 1, comprising a second, upper liquid/gel reservoir removably mounted on the handle which, when fitted, is in fluid communication with the liquid/gel reservoir of claim 1 by virtue of an aperture of the upper liquid/gel reservoir engaging with an aperture of the lower liquid/gel reservoir.

10. A door to which is fitted a door handle according to claim 1.
