Abstract

A battery pack for removable attachment to a portable telephone (2) comprises a housing (1) having a latch (7) for engaging complementary retention means (8) on the telephone, the face of the housing confronting the telephone including a recess (9) for accommodating a complementary raised portion (10) of the telephone, and a pair of spaced apart ribs (12) in the recess abut the raised portion (10) of the telephone when the battery pack is attached causing the battery pack to be urged in a direction to provide more positive engagement between the latch (7) and the retention means (8). <IMAGE>

Description

Batterv Pack This invention relates to a battery pack for removable attachment to a portable telephone.
A known battery pack for removable attachment to a portable telephone comprises a housing having a simple mechanical latch in the form of a cantilevered arm with a barb for engaging complementary retention means on the telephone. The face of the housing confronting the telephone includes a recess for accommodating a complementary raised portion of the telephone. A battery pack having these features is disclosed in the applicant's UK registered design number 2037419.
The applicant has found in practice that the aforementioned battery pack tends to become detached from the telephone when the telephone is inadvertently dropped from a relatively short height, or when it is subjected to some other shock.
According to the present invention there is provided a battery pack for removable attachment to a portable telephone, comprising a housing having a latch for engaging complementary retention means on the telephone, wherein the face of the housing confronting the telephone includes a recess for accommodating a complementary raised portion of the telephone, characterised in that the recess is provided with at least one protrusion which abuts the raised portion of the telephone when the battery pack is attached thereto, whereby the battery pack is urged in a direction to provide more positive engagement between the latch and the retaining means.
A battery pack in accordance with the invention has the advantage that it provides more positive engagement between the latch and the retaining means, which in turn helps to secure the battery pack more firmly in place when it is attached to a telephone. Thus the battery pack is less likely to become detached if the telephone is dropped from a small height or when it is subjected to some other shock.
In a preferred embodiment the protrusion or protrusions are in the form of a rib or ribs which may be disposed on a portion of the recess nearest to the latch.
Suitably there are two spaced apart ribs which help to prevent movement, specifically rotation of the battery pack when attached to a telephone.
Along their length the protrusions may have a substantially uniform cross-section or a tapering cross-section. In either case the cross-section may be semi-circular.
Embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a schematic cross-section of a battery pack in accordance with the invention during removal from a telephone; Figure 2 is a schematic cross-section of a battery pack in accordance with the invention attached to a telephone; Figure 3 is a plan view of the face of the battery housing confronting the telephone; Figure 4 is a cross-section showing a detail of the battery housing in Figures 1 to 3; and Figure 5 is a cross-section showing a detail of a modified embodiment of a battery pack in accordance with the invention.
Referring to Figure 1, there is shown a battery pack 1 which can be removably attached to a portable telephone 2, or to any other suitable portable electronic apparatus.
The battery pack comprises a generally rectangular housing 1 made, for example, of a plastics material enclosing a plurality of rechargeable cells (not shown). The housing comprises an upper part la and a lower part 1b which are suitably fastened together, for example, by snap fitting, adhesive, ultrasonic welding, or by any other suitable means.
Referring also to Figure 3, the edge of the battery pack adjacent the base 3 of the portable telephone 2 comprises a pair of spaced apart lugs 4 having a rounded profile adapted to be accommodated by a complementary recess 5 defined by a lip 6 at the base 3 of the telephone 2. During attachment of the battery pack to the telephone the lugs 4 locate in recesses 5 providing a hinge. The battery pack is thus capable of pivotal motion in the direction of arrow A (see Figure 1).
The edge of the battery pack opposite the lugs 4 is provided with an integral latch 7 comprising a cantilevered arm 7a biased away from the housing 1. The cantilevered arm 7a comprises a barb 7b on the face of the arm 7a opposing the housing. When the battery pack is attached to the telephone, as shown in figure 2, the barb 7b engages a complementary recess 8 in the telephone 2. The barb 7b is urged into engagement with recess 8 under the biasing action of the arm 7a, thus locking the battery pack in place on the telephone.
The face of the housing 1 confronting the telephone 2 includes a rectangular recess 9 for accommodating a complementary raised portion 10 of the telephone. The recess 9 is elongate and extends generally in the longitudinal direction of the housing 1. The recess 9 is disposed centrally on the face of the housing confronting the telephone, taken in the transverse direction of the housing (see Figure 2).
In accordance with the invention, the face 11 of the recess 9 nearest the latch is provided with a pair of spaced apart integral protrusions 12 in the form of ribs extending from the back face of the recess 9 towards the open front face, as shown more clearly in Figure 4. The ribs 12 have a substantially uniform semicircular cross-section along their length. As shown in Figure 3 the ribs 12 are equally spaced about the longitudinal axis of the housing lb in order to help prevent rotation of the battery pack when attached to a telephone.
When the battery pack is attached to the telephone in the fully closed position as shown in Figure 2, the two ribs 12 abut the face 13 of the raised portion 10 of the telephone confronting the recess 9 so that the battery pack is urged in a direction to provide more positive engagement between the latch 7 and the retaining recess 8.
The leading edge 1 2a of the ribs 12 is rounded to prevent jarring against the top edge of the raised portion 10. For the same reason, the outer edge 9a of the recess 9 nearest the base of the telephone and the corresponding edge of the raised portion 10a are both rounded, i.e. they both have a convex profile.
When it is desired to remove the battery pack from the telephone the arm 7a of latch 7 is pressed in a direction towards the housing 1 to release the barb from the retaining recess 8 in the telephone. The battery pack can be detached firstly by pivoting the battery pack about the hinge 4,5, as represented by the arrow A in Figure 1, and then by moving the battery pack in the longitudinal direction away from the telephone, as represented by arrow B in Figure 1.
In a modified embodiment, as shown in Figure 5, the ribs 12 have a tapering semicircular cross-section along their length. The height of the ribs 12 gradually increases towards the front (outer) face of the recess 9. In this embodiment, in order to facilitate removal from the moulding tool, the thickness of the wall portion of the housing supporting the ribs 12 gradually reduces towards the front of the recess.
It will be evident in view of the foregoing description that various modifications may be made within the scope of the present invention. For example there may be more or less than two ribs, and the ribs may have a profile different to that described herein.
