CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the priority of applicant&#39;s U.S. Provisional Application Ser. No. 62/266,658 filed on Dec. 13, 2015. The content of applicant&#39;s Provisional Application is hereby incorporated by reference as thought set forth at length. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    This invention relates to a compact, collapsible chess clock that is operable to be stored in a compact space for transport and storage while concomitantly being operable to be facilely setup into a functional chess clock for accurate timing of game movement activity and a definitive signal of a time dependent chess match winner. 
         [0003]    Chess is a popular game played around the world between two players. Victory is usually determined when a player “checkmates” an opponent&#39;s king. 
         [0004]    With the number of permutations of permissible moves and combinations or sequences of moves competitive chess from a neophyte to master level can be wonderfully complex. Moreover, beginning in 1883, in London, time was added as an element to the game in tournament play to add a further level of skill challenge and player differentiation. Generally speaking, if a checkmate hasn&#39;t decided the game, the player who runs out of time first forfeits a match. 
         [0005]    Chess clocks keep track of each player&#39;s time by decrementing down during a player&#39;s turn. The more time a player takes to make an individual move, the more cumulative time elapses for the player. In tournament play an initial period of two hours is usually allocated to each player to complete forty moves. If one player does not successfully execute forty moves within the precise period of two hours or less the player forfeits automatically. After the primary two hour period a secondary period of an additional hour to execute an additional number of moves can be assigned. Time not used in a player&#39;s primary period can be added to the player&#39;s secondary period. A player utilizes no time consumption at all while an opponent is “on the clock.” 
         [0006]    A game played with the addition of time constraints and forfeiture for failing to meet a time limitation needs an accurate and objective definition of exceeding any set time period in order of both players to radially accept forfeiture from exceeding a time limitation during play. 
         [0007]    Chess clocks have gained in popularity for casual play. A clock not only helps players develop quick cognitive skills, but maintaining a strict time limit for games keeps the length of games to a mutually agreeable limit. Chess clocks have also gained in popularity for use in other one-on-one barad games. Players of other games use time as an element to keep a game moving and to add and additional level of skill to a game. 
         [0008]    In the past analog and digital chess clocks have been known as illustrated, for example, by U.S. Pat. Nos. 2,539,754 and 4,062,180. Such previously known chess clocks; however, have tended to be somewhat bulky and not easily stored or for transported to a lunch or pick-up game in a park or other casual play site. It would therefore be highly desirable to provide a chess clock that could provide a two player, self-actuated chess timing function while concomitantly being compact and easily portable to enable playing a competitive game of chess in a park during lunch—for example. Moreover, it would further be desirable to provide a chess game timing unit that could be facilely set with different time parameters to accommodate different skill levels of a two player board game such as chess. In this an experienced or skill player might be assigned a shorter time period than a less skillful opponent to facilely “level the playing field.” 
       BRIEF SUMMARY OF THE INVENTION 
       [0009]    The subject invention addresses the desires and concerns expressed above by providing a compact, collapsible, digital chess clock, or other game timing device, that is operable to be easily and compactly stored for transport and facilely set up to accurately time opposing player periods “on the clock” in a casual but competitive game environment. 
         [0010]    The subject invention comprises a combination of four triangular interconnected panels that includes a digital electronic system for timing a chess game, or other timed game event, that can be unfolded into an opposing person environment to register accurate player timing visible by both players for both player times while permitting collapse and compact folding for transport and storage.

     DETAILED DESCRIPTION 
       [0018]    As disclosed in  FIGS. 1 and 2  a compact and collapsible chess clock, or other game timing device  10 , is composed of four generally planar, triangular, panels  12 ,  14 ,  16  and  18  that are connected in sequence by hinges  20 ,  22  and  24 . The panels, per se, have a thickness (note  FIGS. 3 and 4 ) and are preferably composed of a polymeric material with the hinges comprising living hinges to facilely permit folding of the panels for compact transport and storage (note  FIG. 6  as an example). 
         [0019]    The first panel  12  includes a player input pad  26  that is operable to receive a player input signal by manually depressing the pad. The panel  12  also includes an array of solar panels  28  that can operably be used to charge an internal panel battery while a game is in progress. 
         [0020]    An adjoining triangular panel  14  is connected to panel  12  by a living hinge  20  and the panel  14  includes an LED light  30  to register a players “on the clock” turn during play. In addition panel  14  includes an up  32  and down  34  arrow button to increase or decrease a player or opponents time clock. 
         [0021]    In a conventional game of chess each player (W and B) can be assigned an agreed set amount of time, which is typically two hours, to accomplish the players primary moves. The large LED hour register  36 , minute  38  and second  40  time digits can be initially set by player W and once play begins can be electronically decremented down while player W is on the clock thinking and then making a move. At the same time that player W is on the clock and his time record is decrementing down on his panel  14  and a concomitant player W time use record is illustrated by smaller LED digits  42 ,  44  and  46  on player B&#39;s play panel  16 . 
         [0022]    All of the component on player W&#39;s panels  12  and  14  are duplicated on similar panels  16  and  18  for player B. In this player B has a set of solar panels  48  that are duplicates of player W panels  28 . Player B has an input pad  50  identical to pad  26  and panel  16  includes a player B set of hour, minute and second digital time registers  50 ,  52 , and  54  which record Player B&#39;s time “on the clock.” 
         [0023]    Player B also has an on the clock LED register  56  and up and down time adjustment arrows  58  and  60  to set the clock at the beginning of a game or to add secondary time. 
         [0024]    Returning briefly to panel  14  the use time record  50 ,  52  and  54  of player B which is recorded on panel  16  and identifies for player B the time that is being used by player B while he is on the clock is also recorded simultaneously in smaller sized digital LED time registers  62 ,  64  and  66  on player W&#39;s visual panel  14 . 
         [0025]      FIGS. 5-6  disclose views of the four panels  12 ,  16 ,  18  and  20  in stages of being folded into a compact triangular structure as depicted in  FIG. 6 . The panels a preferably composed of a flexible polymeric material or silicon rubber and the electronics can be operably embedded and enrobed within the flexible polymeric material. 
         [0026]    In operation player W and B mutually decide the game that is to be played by designating the total time that is to be available to each player which is entered on both clocks using arrows  32 ,  34 ,  58  and  60 . The time appears on the large led register for white and on the small register for B while B&#39;s time appears on the large register for B and smaller on the same register for W. 
         [0027]    Once the game begins W&#39;s time register is started and his game clock decrements down until W makes a move and physically taps time panel  26  which will stop his clock register  36 - 40  and concomitantly start B&#39;s clock  50 - 54 . At the same time the amount of time remaining for W is registered in small LED registers  42 - 46  that is visible to B at the top of his panel  16 . This process goes back and forth as a game progresses until a checkmate is achieved, one player&#39;s time expires with a flashing zero time register for one player means the end of the game by time expiration forfeiture. Alternatively, by mutual consent, the players go into a second time phase segment by agreement where player time can be reentered and the game proceeds. 
         [0028]    Although  FIGS. 1-6  have illustrated a presently preferred embodiment of the subject compact, collapsible, chess clock the subject configuration, the geometric shape of the modules, etc. are meant to be illustrative and not exhaustive. There are an unlimited variety of timing schemes possible. For example, certain matches such as speed chess or fast chess that use small overall time limits (e.g. 25 minutes) add additional time for each move (e.g. 10 seconds). The chess clock can be programed to carry out this or any other timing scheme. The various aspects of the invention were chosen and described in order to best explain principles of the invention and its practical applications. The preceding description is intended to enable those of skill in the art to best utilize the invention in various embodiments and aspects and with modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the following claims.
