This invention relates generally to sliding mechanisms, and more particularly to a sliding mechanism having multiple translating axes.
Slider phones typically slide in one direction and in one plane while opening or closing. This form factor can make for discomfort on the face while using the phone. Other proposed devices having sliding mechanisms include a couple of fixed axes and a single translating axis. Such arrangement creates a device having an overall thickness that is not necessarily desirable. Slider phones also typically have an antenna that is in closer proximity to the users head due to their form factor over flip phones.
Embodiments in accordance with the present invention can provide a sliding mechanism having multiple translating axes that enable products having desirable form factors.
In a first embodiment of the present invention, a slide mechanism can include a first frame having a first frame guide rail, a second frame having a second frame guide rail, a pivot arm coupled between a fixed axis on the first frame and a first translating axis on the second frame, and a second translating axis that translates along the first frame guide rail as the first translating axis translates along the second frame guide rail. The slide mechanism can further include a follower coupled to the first translating axis that slides along the second frame guide rail as the second translating axis slides along the first frame guide rail. The slide mechanism can further include a spring biasing device coupled between the second frame and the follower such as an over-center spring that biases the first frame and second frame in a closed position when on a first side of center and biases the first frame and the second frame in an open position when on a second side of center. Furthermore, the slide mechanism can include a torsion spring coupled on the pivot arm. Note, the fixed axis and the second translating axis can be in substantially the same horizontal plane and vertical plane when the slide mechanism is in a closed position. The fixed axis and the first translating axis can be in substantially the same horizontal plane when the slide mechanism is in a closed position and in substantially the same vertical plane when the slide mechanism is an open position.
In a second embodiment of the present invention, an electronic product can include a front housing coupled to a first frame having a first frame guide rail, a rear housing coupled to a second frame having a second frame guide rail, a pivot arm coupled between a fixed axis on the first frame and a first translating axis on the second frame, and a second translating axis that translates along the first frame guide rail as the first translating axis translates along the second frame guide rail. The electronic product can be any number of devices including, but not limited to a cellular phone, a satellite phone, a smart phone, a personal digital assistant, a laptop computer, a remote control apparatus, a satellite radio, a messaging device, or a satellite positioning system receiver.
The electronic product can further include a display mounted in the front housing and a keypad mounted in the rear housing. A follower can be coupled to the first translating axis that slides along the second frame guide rail as the second translating axis slides along the first frame guide rail. A spring biasing device can be coupled between the second frame and the follower, where the spring biasing device is an over-center spring that biases the first frame and second frame in a closed position when on a first side of center and biases the first frame and the second frame in an open position when on a second side of center. The electronic product can further include a torsion spring coupled on the pivot arm. The front housing can cover a keypad on the rear housing in a closed position and expose the keypad in an opened position. The front housing slides in at least two dimensions when traversing from a closed position to an open position or from the open position to the closed position. Note, the fixed axis and the second translating axis can be in substantially the same horizontal and vertical planes when the electronic product is in a closed position. Also note that fixed axis and the first translating axis can be in substantially the same horizontal plane when the electronic product is in a closed position and in substantially the same vertical plane when the electronic product is an open position.
In a third embodiment of the present invention, a method of sliding a first housing portion in two dimensions relative to a second housing portion can include the steps of coupling a pivot arm between a fixed axis on a first frame of the first housing portion and a first translating axis on a second frame of the second housing portion and translating a second translating axis along a first frame guide rail of the first frame as the first translating axis translates along a second frame guide rail of the second frame.
The terms “a” or “an,” as used herein, are defined as one or more than one. The term “plurality,” as used herein, is defined as two or more than two. The term “another,” as used herein, is defined as at least a second or more. The terms “including” and/or “having,” as used herein, are defined as comprising (i.e., open language). The term “coupled,” as used herein, is defined as connected, although not necessarily directly, and not necessarily mechanically.
While the specification concludes with claims defining the features of embodiments of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the figures, in which like reference numerals are carried forward.
A slider phone in accordance with the embodiments herein can have a two (2) dimensional path instead of a one (1) dimensional path like those found in existing slider phones. The embodiments illustrated can include multiple translating axes and one fixed axis. One moving piece travels up for a predetermined distance relative to another piece such as 25 mm, and then engages a pivot arm which swings one of the moving pieces up to a predetermined angle such as 15 degrees, while continuing to travel up in a Y or vertical direction another predetermined distance such as 20 mm. Such arrangement allows for more comfort on the face of the user and can be more contoured to the user's head. Such arrangement can also increase the distance from the user's head to an antenna on a device having an antenna using such sliding mechanism.

As illustrated electronic product 10 can further include a display 13 mounted in the front housing 12 and a keypad mounted 18 in the rear housing 14. A follower 52 can be coupled to the first translating axis 45 that slides along the second frame guide rail 54 as the second translating axis 46 slides along the first frame guide rail 34. A spring biasing device 56 can be coupled between the second frame 42 and the follower 52, where the spring biasing device 56 is an over-center spring that biases the first frame 32 and second frame 42 in a closed position when on a first side of center and biases the first frame and the second frame in an open position when on a second side of center. The front housing 12 can cover the keypad 18 on the rear housing 14 in a closed position and expose the keypad 18 in an opened position. The front housing 12 slides in at least two dimensions when traversing from a closed position to an open position or from the open position to the closed position.
