ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to radio devices.
In such devices, it is known to equip a housing of the device with an external antenna which projects through an opening in the housing.
Damage to the antenna through snapping, bending or fracture can occur. It is, therefore, a requirement for the radio device that the damaged antenna be readily replaceable.
SUMMARY OF THE INVENTION
With this in mind, in one aspect, the present invention provides a radio device comprising: a housing having an opening and an internal retaining recess; a resilient antenna support sleeve inserted in the opening, the sleeve including a lug projecting into the retaining recess to oppose withdrawal of the antenna support sleeve; an antenna mounted in the antenna support sleeve; the walls of the retaining recess and the surfaces of the lug being shaped such that on rotation of the sleeve the lug is urged inwardly and escapes from the retaining recess.
By virtue of these features, on rotation of the sleeve the lug is urged inwardly and escapes from the retaining recess, thereby facilitating withdrawal of the antenna support sleeve from the housing.
Preferably, the lug comprises a chamfered surface. The chamfered surface on rotation of the sleeve bears against a side wall defining the retaining recess and assists in the progressive inward deformation of the sleeve which helps the lug to escape from the retaining recess. Preferably, the lug comprises a pair of chamfered surfaces such that the same effect can be achieved in either direction. Also, the lug may include a chamfered surface which facilitates the insertion of the lug into the opening.
Preferably, the lug includes a face. The face opposes a top wall defining the recess, whereupon if an attempt is made to withdraw the sleeve from the opening, the face bears against the top wall to oppose this withdrawal.
In a further aspect, the present invention provides an antenna support sleeve suitable for removable insertion into an opening of the housing of a radio device, comprising a tubular wall from which upstands a lug, the wall being sufficiently deformable such that when an inward force is applied to the lug during said insertion the wall deforms but the lug does not.
