ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a foldable mobile wrist communicator according to the preamble of the patent claim
1
. Mobile communicator here means also wireless telephones on the whole.
2. Description of the Prior Art
The patent publication U.S. Pat. No. 5,274,613 presents a watch and a radio telephone mounting on a wrist strap. In the prior art solution a watch and a mobile radio communicator are located in a foldable unit, which can be attached to or disconnected from a wrist strap. The foldable unit is opened out so that the topmost part of the foldable unit pivots out to the left and the middle part to the right as seen from the left hand while the bottom part remains in its initial position. That is to say the foldable unit pivots out tangent to the wrist strap i.e. perpendicular to the arm line. When unfolded the unit functions as a radio telephone which has a microphone on one end and an earphone on the other end of the opened unit.
However, the prior art solution has its disadvantages. Whole electronics has been planned to be inserted in one wrist strappable unit. In this way the unit becomes large and heavy, which makes the usage of the unit on the wrist strap quite inconvenient. Especially the power unit solutions of the mobile communicators still today are of the size and weight class, which are very difficult to fit together with the unit in question. One notable disadvantage is also that because the current supply is fixed when the current supply runs low, the watch and the mobile communicator are out of order till the current supply has been charged again.
The radio mobile communicator of the prior art opens out to a very inconvenient position when it is used on the wrist. When the longitudinal direction is perpendicular to the longitudinal direction of the arm talking to the phone and other usage of the radio telephone is difficult because irrespective of whether the opened out mobile communicator is located inside or outside of the wrist the user must always hold his hand in an unnatural position as he speaks to the phone. In addition, when the watch and the radio telephone are combined it is impossible to use and carry them separately only one at a time.
SUMMARY OF THE INVENTION
The purpose of the present invention is to create a new mobile communicator by which the above mentioned problems can at least to a great extent be removed. In order to facilitate this the mobile communicator constructed in accordance with the principles of present invention is characterized by the preamble of the patent claim
1
. Advantageous embodiments of the invention have been presented in other patent claims.
The present invention has an advantage that the mobile communicator folds out for use parallel to the arm. The unfolded mobile communicator can be used supported by the palm without removing it from the wrist strap. A solution like this improves operation comfortability and increases operation security of the mobile communicator.
One preferred mobile communicator constructed in accordance with the principles of present invention includes another device such as a watch or a television, which has been placed on the same wrist strap. Both devices can be separate units so it is possible to use them separately only one unit at a time, if required. In addition, two separate units arranged to the different sides of the wrist strap make a more balanced and convenient assembly to be worn on the wrist and used than a large combined unit on a wrist strap.
In one preferred mobile communicator constructed in accordance with the principles of present invention the problem of a heavy current supply has been solved using an annular current supply, which can also function as a wrist strap. In this way the weight is distributed especially evenly and both the mobile communicator and the other device can use the same current supply. In addition, when the current supply is exhausted it can be replaced by a charged one and the charged current supply can be used immediately without waiting for the first battery to be charged.
A mobile communicator in accordance with an embodiment of the present invention comprises a wrist strap and an actual mobile communicator connected to it, which has at least two mobile communicator parts, which have been mechanically united by joints so that they can be folded in against one another for a position of repose and can be opened outwardly for a position of use, characterized in that the parts of the mobile communicator are arranged to be opened for use in essentially vertical direction compared with the wrist strap plane.
