ABSTRACT
Add-ons module is using multiple plug projections to improve mechanical joint to a cell phone. The coupling is performed by push-pull action. A substantially larger moment is thus resisting separation of the add-on from the cell phone.

CLAIMS(2)
WHAT IS CLAIMED IS:
A cell phone add-on comprising:
a body having a number of sides, one of the sides having a plurality of projection plugs, said projection plugs separated at a distance from each other, said projection plugs fitting plug ports of a cell phone;
so that the add-on can be mechanically coupled to a cell phone by applying a push force and removed by a pull force.
2. The cell phone ad-on of claim 1, wherein the projection plugs are the audio male plug and the communication male plug.

DESCRIPTION
Cell Phone Add-on FIELD OF INVENTION
[0001] The present invention relates to a cell phone. More particularly this invention pertains to an add-on module mechanically coupled to a cell phone.

BACKGROUND OF THE INVENTION
[0002] Present designs of add-ons to a cell phone are based on a relatively large communication plug to couple an add-on module to the phone body. The add-ons provide extra features to the cell phone such as an additional battery, image projector, cooling propeller, perfume pumper or a medical device. Such modules are plugged only temporarily into the cell phone and a sturdy mechanical joint is not required.
[0003] However, there seem to be a need on the market for cell phone add-ons which would enhance the appeal for cell phone especially in the luxury market. Such modules could be a mechanical/electrical watch, jewelery or a precious materials art object. Unfortunately present designs of the add-ons do not provide a sufficient mechanical coupling since they are based on a singular connection. Newer cell phones such as I-phone5 have even reduced size communication port. Such port is suitable for electrical connection docking station such as Belkin Charge+Synch Dock, but not sturdy enough to join a sizable add-on module.

SUMMARY OF THE INVENTION
[0004] Accordingly one object of the present invention is to create improved mechanical coupling between the cell phone and the add-on.
[0005] In order to achieve this objective the communication port, as well as the audio port of the cell phone are employed simultaneously to create a mechanical coupling with the add-on. The coupling is separable by push-pull action and securing of the add-on is provided by the retention mechanism of the cell phone ports. The improved mechanical joint is achieved because the cell phone ports are located at the distance relative to each other. A
substantially larger moment is thus resisting separation of the add-on from the cell phone. Further advantage is that the potentially damaging strain to the port components is thus reduced while using the add-on for an extended time.
[0006] This summary of the invention does not necessarily describe all features of the invention. In the following the invention will be described in detail with reference to the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 shows a perspective elevation of the add-on and of the cell phone in orientation before pushed together.
[0008] Figure 2 shows a perspective elevation of the cell phone and add-on coupled together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] With reference to Figure 1 there is illustrated a cell phone 1 and an add-on module 2. The add-on is intended to be coupled to the cell phone by pushing in the direction 3. The add-on incorporates two male projections, communication plug 4 and audio plug 5, separated at the distance 6. While pushing the add-on 1 in the direction 3 the two male plugs fit into the corresponding female component at the ports of the cell phone. The cell phone female components are separated at the same distance 6 as the add-on male projections.
[0010] One advantage of the preferred embodiment is that the two port joint coupling resists substantially a separation between the cell phone and the add-on while subjected to the moments 7 and 8 as shown in figure 2.
