## Title
Gel grip controller

## Abstract

The present invention is directed to a controller having a gel-gripping surface for engagement with a user's hand. The controller includes a housing having a plurality of operation members logistically positioned for manipulation by a user's hand. A handle portion adapted to be grasped by the hand of a user includes a deformable gel-grip extending over a substantial portion of the handle. The gel grip includes a flexible external exposed surface containing a semi-liquid flowable material within a cavity portion of the gel-grip. Such an arrangement provides a multi-directional deforming gripping surface with a comfortable feel.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a video game controller and more particularly to a controller with an integrated gel-grip.
2. Discussion of the Related Art
Video game controllers are also well in the art and conventionally employ a hard plastic housing to be grasped by the user. Such conventional controllers are uncomfortable and after significant use can cause blistering, perspiration and otherwise cause discomfort and poor performance for the user. U.S. Pat. No. 6,120,025 attempts to alleviate some of the problems associated with conventional controller grips by providing a simple covering material secured to the controller. (U.S. Pat. No. 6,120,025 is herein incorporated by reference.) Other attempts to provide cooling have been to incorporate a fan and force air through the controller. While the prior art grips may provide slight relief, they do not provide the level of comfort and feel as that of the present invention as heretofore described.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a controller with a gel-gripping surface for engagement with a user's hand thus overcoming the shortcomings of the prior art devices. The controller includes a housing having a plurality of operation members logistically positioned for manipulation by a user's hand. A handle portion adapted to be grasped by a hand of a user includes a deformable gel-grip extending over a substantial portion of the handle. The gel grip includes a flexible external exposed surface containing a semi-liquid flowable material within a cavity portion of the gel-grip. Such an arrangement provides a multi-directional deforming gripping surface with a comfortable feel.

DESCRIOTION OF THE PREFERRED EMBODIMENTS
FIG. 1 depicts a video controller having a plurality of operational members, such as a pair of stick controls 3, a D-pad 5, and a host of other conventional operational buttons. Each of the members providing operational control over respective characteristics of a given game. Two handle portions 7a, 7b extend from a central housing portion and are contoured to be grasped by a hand of a user. Conventionally, the controller is grasped simultaneously by two hands on each on a corresponding handle 7a, 7b. A deformable gel-grip 11 is secured to the each handle covering a substantial portion of the handle to provide conform and superior feel to the user. The details of the gel-grip will be explained in further detail below.
FIG. 2 depicts a gel-grip 11 according to one embodiment of the present invention. A retaining flanged 13 made of a substantially rigid material such as ABS plastic forms the outer boundary of the grip extending along the outer periphery and maintains the shape of the gel-grip. A flexible material 11 extending across a substantial portion of the external surface of the grip contains a semi-liquid flowable material within a closed cavity portion of the grip 11. Referring to FIG. 3, in one embodiment the retaining flange 13 has a back surface 13a substantially conforming to the external surface of the handle 7. A peripheral lip portion 13b lip extends along the outer periphery of the gel-grip defining its outer boundaries. The flexible material, such as fabric, is secured to the peripheral lip. The flowable semi-liquid material 13c is disposed between the back surface 13a and the flexible material 11. The retaining flange 13 is directly secured to the handle 11 with an adhesive or positive means as in an alternate embodiment which will be discussed later.
The gel material 13c may be contained directly between the flexible material 11 and back surface 13a of the flange. However, it is preferred to use a bladder filled with the gel 13c to ensure containment over the life of the grip and simplify the manufacture of the gel-grip. The gel 13c material may be a silicone based gel. For example, the gel material may be formed of a silicone psuedogel material as disclosed in U.S. Pat. No. 5,741,877, or that disclosed in U.S. Pat. No. 4,558,112, each of which is herein incorporated by reference. The material 13c needs to be flowable and semi-liquid while having sufficient viscous properties to provide sufficient feel of the controller while simultaneously providing superior comfort. The gel grip provides an exposed external gripping surface that s capable of simultaneously moving both orthoganally and translationally relative to handle during deformation when grasped by a users hand. The Gel grip of the present invention provides a superior balance between comfort and feel which here-to-for has not been recognized in the prior art controllers.
FIG. 4 represents an alternate embodiment according to the present invention. In this embodiment, the retaining flange 113 is formed of a band member 113b extending along a substantial portion of the periphery of the gel grip. The gel filled bladder 113c and flexible material are simply adhered to the retaining flange 113. The retaining flange 113 and back surface of the gel filled bladder 113 are together adhered to an external surface of the handle 7a. The flexible material 111 may also extend over the back surface of the bladder (not shown) to define a closed cavity with the flange and the back surface of the flexible material and flange adhered to the handle 7a. 
FIG. 5 represents an alternate embodiment of the present invention. Rather than adhering the gel grip to the handle, a connecting member engages a corresponding portion of the handle portion thereby providing a positive connection between the gel-grip and the handle 7. The connecting member includes a plurality of locking tabs 31 having a detent 33 formed proximate a terminal end. The locking tab 31 extends from an underneath portion of said gel-grip and engages the handle 7a through a recess 41 thereby providing said positive connection between the gel grip and handle 7a. FIG. 6 depicts a detailed view of the connection between the gel-grip and handle 7a. 
FIGS. 7–8 depict alternate embodiments with connections between the gel-grip and handle 7a. In this embodiment the connecting member includes a closed lip 8 disposed on an underneath portion of the retaining flange 13 and engaging a corresponding groove 8 formed along an opening in the handle 7a thereby providing a snap-fit removable connection between said gel-grip and the handle 7a. The close lip 8 replaces the locking tab of the previous embodiment extending continuously around the underneath portion of the flange 13 as shown in FIG. 8. While the retaining flange is substantially rigid, such as formed of ABS plastic, it may be deformed slightly. To remove the gel-grip from the handle 7a, the retaining flange 13 need simply be pinched between thumb and forefinger to deform the flange 13 to unseat the lip from the groove. The flange 13 and lip 8 may simply be pushed into seating with the groove 8a in a snap-fit fashion. This arrangement provides for the ability to interchange gel-grips of differing color etc. and otherwise allow for replacement of the grip. A locking tab 51 having a bore 53 may also be provided to engage a peg 61 disposed within the handle 7a. To install the gel-grip, the flange 13 is simply pinched to deform the locking tab inward to clear the peg 61, when the flange 13 is released, the bore 53 slides over the peg 61 and the lip seats within the groove 8 and the gel grip secured to the handle 7a. 
While the present invention has been shown and described with reference to specific embodiments forming the best mode, various changes in form and detail may be made without departing from the spirit and scope of the invention.
