defined by

opposite ends

26 and 28 and

opposite sides

30 and 32. In the illustrated'ernbodirnent for'playing a skiing-type game, end 26 of the playing surface 24 is the starting" end and end 28 is the finish end. A gutter structure 34 peripherally surrounds the playing surface 24 for receiving playing members which may inadvertently be propelled over one of the edges of the playing surface. v

In accordance with the invention, the playingsurface 24, in

cross section, is straight throughout its area in the direction parallel with

side edges

30 and 32, as shown by the arrows 36, and is convexly curved throughout its area in the direction parallel with the

end edges

26 and 28, i.e., transverse to the direction 36, as shown by the arrows 38.

The garneboard 22 is supported upon a supporting surface (not shown) by tilfing apparatus 40 which provides tilting movement for the board 22 and its playing surface 24 about a first axis 22 parallel with the direction 38 and a second axis 44 parallel with the direction 36. Tilting assembly 40 comprises a supporting member 46 adapted to be supported upon the supporting surface and having a pair of spacedapart, upstanding posts 48 and 50 formed thereon. Pivot member 52 extends between and is pivotally supported bythe posts 48 and 50 for pivotal movement about the axis 42. A mounting member 54 is mounted on the bottom surface 56 of the playing surface 24 and has a post 58 depending therefrom. Another pivot member 60 is provided having one end secured to post 58 and extending on the axis 44. Pivot member 60 is rotatably seated in opening 62 formed in the pivot member 50 at right angles to the axis 42, as indicated by the dashed line 64, and is secured in position by means of a suitable collar member 66.

A pair of manual manipulating

handles

68 and 70 are respectively secured to the board 22' extending outwardly from end 72 of the gutter structure 34 which is adjacent the finish" end 28 of the playing surface 24.- It will thus be seen that the game board 22 and its playing surface 24 may be manipulated manually by the

handle members

68 and 70 to provide a compound tilting movement, the board and playing surface being tilted about axis 42, as shown by the arrows 74, and also tilted about the axis 44, as shown by the arrows 76.

. In the illustrated embodiment for playing a skiing-type game, a plurality of abutments in the form of flags 78 are provided in' spaced-apart relation along the longitudinal center line of the playing surface 24, i.e., midway between the'side

edges

30 and 32, the flags 78 thus simulating a slalom skiing course. Each of the flags 78 is preferably mounted for rotational movement on the playing surface 24. A rolling playing member 80, which may take any of the forms shown in FIGS. 8 through 12, is provided which rolls upon the playing surface 24 between the start" end 26 and the finish" end 28 in response to manipulation of the

handles

68 and 70, the object of the game being to cause the rolling playing member 80 to traverse the path defined by the flags 78 in slalom fashion as indicated by the dashed line 82. By reason of the rotatable mounting of the flags 78 upon the playing surface 24, flags 78 maybe initially oriented in a direction parallel with the center line thus a given flag hit by therolling member 80 will be turned to a different position indicating engagement with the member 80. As will be more fully described in connection with FIGS. 8 through 12 inclusive, the rolling playing member 80 has a frustoconical rolling surface, the combination of this frustoconical rolling surface and the convexly curved playing surface 24 increasing the manipulative dexterity required in order to cause the rolling member 80 to traverse the slalom course 82 without impinging upon any of the flags 78.

Referring now to FIGS. 3 and 4, in which like elements are indicated by like reference numerals, another embodiment of the invention is shown in which the game board 22 and its playing surface 24 are manipulated by a single joy stick type control lever 84. Here a supporting frame 86 is provided adapted to be supported upon the supporting surface 88. A bearing member 99 is provided mounted on the frame 86 aligned with the axis 44 and pivot member 100 is journaled in the bearing member 99. A first lever member 102 is provided having its upper end mounted on the game board 22 and depending therefrom and being pivotally connected intermediate its ends to one end of the pivot member 100, as at 104. The manipulating handle member 84 comprises a second lever member 106 having a grip portion 108 on its upper end and being pivotally connected intermediate its ends to the other end of the pivot member 100 as at 110. The lower ends 112 and 114 of the

lever members

102 and 106 are connected by a link member 116. It will be seen that movement of the manipulating handle 84 between the position shown in solid lines in FIG. 4 and the position shown in dashed lines will result in pivotal movement of the game board 22 about axis 42 which extends through pivot 104, as shown by the arrow 74, and that side-to-side movement of the manipulating handle 84, as shown by the arrows 118 will result in pivotal tilting movement of the game board '22 about axis 44 as shown by the arrows 76.

In this illustrated embodiment, the abutments or flags 78 are shown arranged on the playing surface 24 of the game board 22 in a circular pattern for playing a different form of game, it being understood that the abutments or flags 78 may be arranged in a desired pattern, or even in a random pattern, upon the playing surface 24.

Referring now to FIGS. 5, 6 and 7, the game board 22 and its playing surface 24 may be supported upon the supporting surface 88 for dlting movement in all directions rather than for two-axis tilting movement as in the case of the previous embodiments. Referring to FIG. in which like elements are indicated by like reference numerals, a supporting member 120 is provided adapted to be supported upon the supporting surface 88 and having a post 122 extending upwardly therefrom. Post 122 has a spherically-shaped portion 124 formed on its upper end which cooperatively engages a spherically-shaped recess 126 formed in a mounting member 128 which is mounted on the lower surface 56 of the playing surface 24. 2

Referring to FIG. 7 in which like elements are still indicated by like reference numerals, in the simplest form of the invention, a mounting member 130 is mounted on the abutment surface 56 of the playing surface 24 and has a post 132 depending therefrom. Post 132 has a spherically-shaped portion 134 formed on its lower end which engages the supporting surface 88.

Referring now to FIG. 6 in which like elements are still indicated by like reference numerals, a supporting member 136 is provided adapted to be supported upon the supporting surface 88 and having a post 138 extending upwardly therefrom. A mounting member 140 is mounted on the bottom surface 56 of the playing surface 24 and has a post 142 depending therefrom. An elongated, multicoil relatively stiff coil spring 144 is provided having its opposite ends respectively seated.

upon the

posts

138 and 142 and extending therebetween, thereby providing the omnidirectional tilting movement of the game board 22 and its playing surface 24.

Referring now to FIG. 8, in one embodiment thereof, the rolling playing member may take the form of a solid member 146 having opposite ends 148 and 150 joined by a continuous frustoconical rolling surface 152.

Referring to FIG. 9 in which like elements are indicated by like reference numerals, the rolling playing member 146, rather than being solid as in the case of FIG. 8, may be in the form of an annulus having a frustoconical interior surface 154,

asshown.

Referring now to FIG. 10, the rolling playing member 80 may comprise a pair of

circular disc members

156 and 158 coaxially mounted in spaced-apart relationship upon an axle member 160. Disc member 156 is smaller than disc member 158 and thus the

peripheral edges

162 and 164 of

disc members

156 and 158 mutually define the frustoconical rolling surface.

Referring now to FIGS. 11 and 12 in which like elements are indicated by like reference numerals, an indicator member 166 may be provided rotatably mounted on the axle and projecting radially outwardly beyond the frustum, as indicated by the dashed line 168. More particularly, the indicator member 166 may comprise a member 170 formed of relatively thin sheet metal and having an upper portion 172 uponwhich a decorative image of a skier may be suitably formed, as suggested in FIG. 12. Member 170 has a generally U-shaped portion 174 formed at its lower end having an opening 176 formed therein. A weight member 178 is provided having a central ppening 180 which rotatably receives the axle 160 and having a pointed upper end 182 which is received in the opening 176 in portion 174 of member 172, thus attaching the same. While thus attached it will be seen that the weight member 178 will retain the indicator member 170 in an upright position. In this embodiment, the

peripheral edges

162 and 164 of the

disc members

156 and 158 are beveled further to define the frustum 168, as shown.

The game of the invention as aforementioned is played by manipulating the game board 22 in a manner to cause the playing member 80 to traverse the playing surface 24. With reference to the above-described embodiment in which the flags 78 are arranged in a row in a manner simulating a slalom skiing course, individual players can compete by measuring the length of time it takes for the playing member 80 of an individual player to traverse the course 82. With reference to the embodiment illustrated in FIG. 3, the game may be played by measuring the time it takes for an individuals playing member 80 to roll radially of the circular pattern of flags 78 and to circumnavigate each of the flags 78. Alternatively, the

total number of each of the flags hit by the playing member 80 in a given period of time by each of the players can be recorded as a score. As above mentioned, the flags 78 are rotatably mounted to the playing surface 24 such that the flags 78 when hit by the playing member 80 will turn thus indicating the score at the end of each players turn.

While there have been described above the principles of this invention in connection with specific apparatus, it is to be clearly understood that this description is made only by way of example and not as a limitation to the scope of the invention.
