The present invention is directed to video game controllers, and more particularly to a video game controller with a detachable joystick.
Video gaming is very popular and has become increasingly complex, requiring video game controllers with multiple inputs (e.g., buttons, joysticks) that can be actuated (e.g., pressed, pivoted, etc.) to activate functions within the video game. As the inputs are actuated, electrical signals are generated, processed and/or transmitted to a gaming console to which the controller connects. The console operates the video game at least in part based on the signals it receives from the controller. There are different gaming consoles in the market, and each console may use a different type of controller (e.g., having different types or combination of inputs) or accommodate the use of multiple types of controllers.
Some game controllers are designed for particular use in fighting games or arcade style games. Such controllers can have an arcade like joy stick and multiple buttons, and a base or housing that allows the user to optionally rest his or her wrists on the housing of the controller while actuating the controls (e.g., the joy stick and/or buttons). Though such controllers are portable, they are often much larger than typical hand held controllers and the joystick that sticks out of the body of the controller makes it difficult to store the controller when traveling as it does not easily fit in a typical backpack, messenger bag or suitcase. Moreover, when placed in a travel bag (e.g., back pack, messenger bag, suitcate), the joystick sticking out of the controller housing can result in pressure exerted on the joystick head, which can result in damage to the joystick and/or the controller. To address these problems, removable joysticks have been developed for use with such controllers, to allow the controller to better fit in a travel bag. However, such removable joysticks are still deficient. For example, the dust cover is not retained when the joystick is removed, which results in the dust cover being misplaced or lost, which can negatively affect the operation of the controller (e.g., due to ingress of dust, liquid or other matter into the controller via the opening the dust cover normally covers, which can cause the joystick actuator to malfunction or fail.
Accordingly, there is a need for an improved video game controller with a removable joystick that solves the problems discussed above.
In accordance with one aspect, a removable joystick for use with a video game controller is provided. The removable joystick includes a base shaft coupleable to a joystick unit in the video game controller. The removable joystick also comprises a top shaft assembly removably coupleable to the base shaft. The top shaft assembly includes a top shaft with a proximal end that optionally removably couples to a joystick ball. The top shaft assembly also includes a collar that is spring loaded and movably coupled to the top shaft and has a flange that extends outward from the outer surface of the collar. The top shaft assembly removably couples to the base shaft via a quick disconnect connection (e.g., ball-lock connection). When the top shaft assembly is disconnected from the base shaft, the flange of the collar engages and retains a dust cover disposed over the collar to inhibit misplacement or loss of the dust cover. This assembly facilitates travel with the video game controller by allowing decoupling of the joystick while preventing misplacement or loss of the dust cover.
In accordance with another aspect, a removable joystick assembly for use with a video game controller is provided. The removable joystick assembly comprises a base shaft with a circumferential recess at a proximal end of the base shaft and a top shaft assembly removably coupleable to the base shaft. The top shaft assembly comprises a top shaft having a central bore and comprising a threaded proximal end configured to removably couple to a joystick ball, a circumferential slot at a location between the proximal end and a distal end of the top shaft configured to removably receive a clip, and a plurality of openings defined in a distal wall portion of the top shaft that are configured to movably retain metal balls therein. The top shaft assembly also comprises a collar movably coupled over the top shaft by a spring disposed between the clip on the top shaft and an inner shoulder in the collar. The collar comprises a proximal inner surface with a first diameter that defines an annular gap between the top shaft and the collar that receives the spring, the first diameter being greater than a diameter of an outer surface of the top shaft. The collar also comprises an intermediate inner surface with a second diameter different than the first diameter and configured to contact an outer surface of the top shaft at the location of the plurality of openings to bias the balls in the openings radially inward relative to the distal wall portion of the top shaft. The collar also comprises a distal inner surface with a third diameter greater than the second diameter and configured to be spaced from the an outer surface of the top shaft at the location of the plurality of openings to allow the balls in the openings to more radially outward relative to the distal wall portion of the top shaft. The collar also comprises a flange extending radially outward from a distal portion of the collar. The spring biases the collar toward a distal position where the intermediate inner surface biases the balls in the openings radially inward and into the circumferential recess of the base shaft to couple the top shaft assembly and the base shaft. When the collar is pulled proximally, the distal inner surface is spaced from the plurality of openings so that the balls move radially out of the circumferential recess thereby decoupling the top shaft assembly from the base shaft. The flange on the collar is configured to engage a dust cover disposed over collar to retain the dust cover when the top shaft assembly is decoupled from the base shaft.
In accordance with another aspect, a kit for a removable joystick assembly for use with a video game controller is provided. The kit comprises a base shaft with a circumferential recess at a proximal end of the base shaft, and a top shaft assembly removably coupleable to the base shaft. The top shaft assembly comprises a top shaft having a threaded proximal end, a circumferential slot at a location between the threaded proximal end and a distal end of the top shaft having a clip disposed therein, a plurality of openings defined in a distal wall portion of the top shaft, and a plurality of metal balls movably retained in the plurality of openings. The top shaft assembly also comprises a collar movably coupled over the top shaft, a spring disposed between the clip on the top shaft and an inner shoulder in the collar to allow spring loaded movement of the collar relative to the top shaft between a distal position and a proximal position, the collar having a flange extending radially outward from a distal portion of the collar. The spring is configured to bias the collar toward a distal position so that the collar biases the balls in the openings radially inward and into the circumferential recess of the base shaft to intercouple the top shaft and the base shaft. When the collar is pulled proximally, an inner surface of the collar is spaced from the plurality of openings so that the balls move radially out of the circumferential recess to decouple the top shaft assembly from the base shaft. The flange is configured to engage a dust cover disposed over collar to retain the dust cover when the top shaft assembly is decoupled from the base shaft.
In accordance with another aspect, a video game controller and a removable joystick assembly are provided in combination. A base shaft has a circumferential recess at a proximal end of the base shaft and a distal end coupled to a joystick unit in the housing of the video game controller. A top shaft assembly is removably coupleable to the base shaft. The top shaft assembly comprises a top shaft having a threaded proximal end removably coupleable to a joystick ball, a circumferential slot at a location between the threaded proximal end and a distal end of the top shaft having a clip disposed therein, a plurality of openings defined in a distal wall portion of the top shaft, and a plurality of metal balls movably retained in the plurality of openings. The top shaft assembly also comprises a collar movably coupled over the top shaft, a spring disposed between the clip on the top shaft and an inner shoulder in the collar to allow spring loaded movement of the collar relative to the top shaft between a distal position and a proximal position, the collar having a flange extending radially outward from a distal portion of the collar. The spring is configured to bias the collar toward a distal position so that the collar biases the balls in the openings radially inward and into the circumferential recess of the base shaft to intercouple the top shaft and the base shaft. When the collar is pulled proximally, an inner surface of the collar is spaced from the plurality of openings so that the balls move radially out of the circumferential recess to decouple the top shaft assembly from the base shaft. The flange is configured to engage a dust cover disposed over collar to retain the dust cover when the top shaft assembly is decoupled from the base shaft, a proximal end of the base shaft disposed at or below a top surface of the housing.
The controller 100 can optionally have one or more buttons 30 on the top surface 12 for actuating one or more functions of the video game during operation. The controller 100 also have a joystick unit 40 that includes a joystick assembly 50. The user can pivot the joystick assembly 50 to actuate a function of the video game during operation. A dust cover 46 is disposed about the joystick assembly 50 and adjacent the top surface 12 of the housing 10. The dust cover 12 covers an opening 14 in the housing 10 within which the joystick assembly 50 pivots to inhibit ingress of dust and foreign material into the housing 10 via the opening 14.
The joystick assembly 50 includes a base shaft 52 that can be coupled to the actuator 42 with a clip 44 (e.g., e-clip) that extends in a slot 52A at a distal end of the base shaft 52. The base shaft 52 can have a bore 52B that extends along its length, and can also have a circumferential recess 53 near a proximal end of the base shaft 52. The base shaft 52 can have a conical surface 52C adjacent the circumferential recess 53 that extends to a shoulder 52D.
The joystick assembly 50 also includes a collar 54 with a flange 55, where the collar 54 is movably mounted onto a top shaft 56 to define a quick release or quick disconnect fitting (e.g., a ball-lock quick disconnect). The flange 55 can optionally extend radially outward from the collar 54 by a distance of between about 0.5 mm and about 3 mm, such as about 1 mm or about 1.2 mm. The collar 54 can have a shoulder 54A that extends radially inward from an inner surface of the collar 54, a proximal cylindrical section 54B with a first inner diameter D1, an intermediate cylindrical section 54C with a second inner diameter D2, and a distal cylindrical section 54C with a third inner diameter D3. Diameter D1 and Diameter D3 are greater than diameter D2, and diameter D3 is optionally greater than diameter D1.
A spring 57 can be disposed over at least a portion of the top shaft 56 and between the top shaft 56 and the collar 54 and allows the collar 54 to be spring loaded relatively to the top shaft 56. As best shown in
In use, when the collar 54 is in the biased position and the top shaft 56 is disposed over at least a portion of the base shaft 52, the balls 58 slide into the circumferential recess 53 of the base shaft 52 to intercouple the top shaft 56 to the base shaft 52. When the collar 54 is slid toward the proximal position (acting against the spring force), the intermediate cylindrical section 54C slides out of contact with the surface of the top shaft 56, allowing the balls 58 to move at least partially into the openings 56A in the top shaft 56 and out of the circumferential recess 53 of the base shaft 52 as the top shaft 56 is pulled away from the base shaft 52. Therefore, the top shaft 56, with the ball 60 attached thereto, and the collar 54 can be decoupled from the base shaft 52 to facilitate travel of the controller 100. Optionally, when the collar 54 and top shaft 56 are decoupled from the base shaft 52, the base shaft 52 does not protrude from the opening 14 of the housing 10 (e.g., the base shaft 52 extends to a proximal end that is at or below a plane of the top surface 12), thereby making it easy for the controller 100 to fit into a back pack, travel bag or suitcase and inhibit damage to the controller 100 or joystick during travel.
Advantageously, as the collar 54 and top shaft 56 are decoupled from the base shaft 52, the flange 55 of the collar 54 engages a surface of the dust cover 46 so that the dust cover 46 is retained on the collar 54. This advantageously inhibits (e.g., prevents) the misplacement or loss of the dust cover 46 while the top shaft 56 and collar 54 are decoupled from the base shaft 52, such as during storage or travel of the controller 100.
