 11 Claims. 4 Drawing Figures TUMBLE DETECTOR BACKGROUND OF THE INVENTION This invention relates generally to a tumble detector and. more particularly. to a detector for accompanying goods to be transported to determine whether the goods have been transported in a recommended position.  
  There are a great number of materials the nature of which requires that they be transported in a certain position. The usual means of fulfilling this requirement consists of certain instructions marked on the crates. such as arrows. These precautions prove to be insufficient since it is very common for materials to be received at their destination in a damaged condition and there always remains the suspicion that. at some time during transport. the recommended position has been changed. However. it is not possible to prove that this is so and. therefore. no grounds exists to claim damages from the carrier.  
  What is needed therefore is a device that indicates. on arrival of materials at their destination. whether they have been transported in the recommended position or not. The device should be capable of detecting not only the fact of improper transport. but also the number and direction of tumbles made in the region of 90. The purpose of the present invention is to provide such a device.  
 SUMMARY OF THE INVENTION According to the principal aspect of the present invention. there is provided a simple and inexpensive tumble detector for accompanying goods to be transported to determine whether the goods have been transported in a recommended position. The detector comprises a closed container having a transparent face for viewing the interior of the container. Partition means are formed in the container which define a labyrinth. A plurality of different colored balls are located in the labyrinth. The labyrinth is shaped so that the balls assume a predetermined different position in the container depending upon the amount and direction of turning of the container resulting from the handling undergone by the goods during transport.  
 BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a perspective view of one form of the detector of the present invention:  
 FIG. 2A is a top plan view of the tumble detector in its correct position. while FIGS. 28. C. D and E show the detector rotated through four counterclockwise quarter turns while FIGS. 28&#39;. C. D&#39; and E show the detector rotated through four clockwise quarter turns;  
  FIG. 3 is a perspective view of a second form of the detector of the present invention; and  
  FIG. 4A is a top plan view of the detector illustrated in FIG. 3 shown in its correct position while FIGS. 43. C. D and E show the detector rotated through four counterclockwise quarter turns and FIGS. 48&#39;. C. D and E show the detector rotated through four clockwise quartcr turns.  
 DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference is now made to FIGS. I and 2 of the drawings in detail. which illustrate one form of the tumble detector of the invention. generally designated [0. The  
 detector comprises a closed circular container 12 having a transparent face I4 and a circular perimeter 16. A partition arrangement is provided in the container 12 made up of a plurality of walls which are perpendicular to the face I4 of the container. This partition defines a symmetrical labyrinth. More specifically. the partition arrangement includes a wall 18 which extends radially from adjacent the center 20 of the container to the circular perimeter 16. A second wall 22 is aligned with the wall l8 and extends inwardly from the perimeter I6 toward the wall l8 but is spaced therefrom. As can be seen from FIG. 2. the walls 18 and 22 divide the container into two equal sides.  
  A third wall 24 is provided on each side of the container. The wall 24 is joined to the wall I8 adjacent to the center 20 of the container. A fourth wall 26 is also provided on each side of the container. This wall is joined to the wall 18 between the center 20 ofthe container and the perimeter 16. The walls 24 and 26 on each side of the container diverge outwardly from the wall 18 toward the perimeter l6.  
  A fifth wall 28 is also provided on each side of the container. Each fifth wall is joined to the wall 22 between the ends thereof and extends around the wall 24 toward the wall 26. More specifically. the fifth wall includes a first section 30 which is joined to the wall 22 and a second section 32 which is generally perpendicular to the wall 26.  
  A sixth wall 34 is also provided on each side of the container. This wall extends from the perimeter 16 out side of the wall 28 toward the wall 26. Preferably the wall 34 and the second section 32 of the wall 28 are parallel to each other.  
  A seventh wall 36 is formed on each side of the container and extends from the circular perimeter I6 adjacent to the end of the wall 26 toward the wall 34.  
  Four different colored balls 38. 40. 42 and 44 are provided in the container l2. A fewer number of balls could be utilized but such fewer number of balls would not indicate as many different turns as with four balls. While the balls have been described as being colored. they could. if desired. be of the same color if suitably marked so as to be distinguishable from one another. Except for the walls of the partition arrangement which are joined to each other or to the perimeter [6 of the container I2. the spacing between the walls is greater than the diameters of the balls.  
  To use the detector It). the detector is placed inside the crate to be transported in the position illustrated in the FIG. 2A. FIGS. 2B. C. D and E show the tumble detector rotated 90. I&#34;. 270. and 360 in the counterclockwise direction. FIGS. ZB&#39;. C. D and E show the tumble detector rotated I80. 270 and 360 in the clockwise direction. It is seen from each view in FIG. 2 that the balls in the detector I0 assume predetermined different positions for each quarter turn. which positions provide an indication of the amount and direction of turning of the crate resulting from handling undergone by the crate during transport. The position of the balls in the detector are checked upon arrival of the crate at its destination. If this position differs from that shown in FIG. 2A. a claim backed by sufficient evidence can be made against a carrier for damage to the goods.  
  From an inspection of the different positions illustrated in FIG. I. it is easy to ascertain the position the balls would occupy. when the tumble detector. after being overturned several times in one direction. is over turned again one or more times in the opposite direc tion. FIG. 2 only shows the position of the tumble detector after four counterclockwise and clockwise turns. so as not to make the drawings exhaustive and considering that this number of turns is enough to detect the anomalies in normal transportation. Nevertheless. from an inspection of the FIGS. the positions of the tumble detector in successive turns can be ascertained,  
  Reference is now made to FIGS. 3 and 4 of the drawings. which illustrate a modified form ofthe detector of the invention. generally designated 50. This detector comprises a rectangular container 52 which has a transparent face 54. The rectangular container includes a pair of short parallel sides 56 and 58 and two longer parallel sides 60 and 62 which are perpendicular to the sides 56 and 58.  
  A partition arrangement is provided in the container 50 which defines an asymmetrical labyrinth. rather than a symmetrical labyrinth as in the embodiment illustrated in H65. 1 and 2. The partition arrangement in the detector 50 is made up of a plurality of walls which are perpendicular to the face 52 of the detector, More specifically, a first wall 64. of generally U-shaped configuration. is centrally positioned within the container S2. The U-shaped wall 64 faces one of the shorter sides 56 of the container. The U-shaped wall 64 includes a pair of legs 66 and 68 which diverge slightly outwardly from each other. A second wall 70 extends between the end ofthe leg 68 to the side 60 of the container. An inwardly extending projection 72 is formed on the leg 68 adjacent to the wall 70.  
  A generally V-shaped third wall 74 is joined at its apex 76 to the side 56 of the container. A fourth wall 78 is joined to the side 58 of the container and extends at an angle toward the side 60 thereof. A fifth wall 80 is joined to the side 62 of the container and extends at an angle toward the side 58. More specifically. the fifth wall 80 includes a first section 82. a second section 84. and a third section 86. The first section is joined to the side 62 and lies generally perpendicular to the leg 88 of the V-shaped wall 74. The second section 84 of the fifth wall extends generally parallel to the leg 66 of the U-shapcd wall 64. The third section 86 of the fifth wall lies generally perpendicular to the wall 78.  
  As in the embodiment illustrated in FIGS. 1 and 2. four different colored balls 90. 92. 94 and 96 are positioned in the labyrinth defined by the walls in the container 52. Except where the walls are joined to each other or to the sides of the container. the walls are spaced apart a distance greater than the diameters of these balls.  
  In use. the detector is placed inside a crate in the position illustrated in FIG. 4Av H65. 48. C. D and E show the detector rotated through quarter turns in the counterclockwise direction while FIGS. 48&#39;. C. D and E show the detector rotated through quarter turns in the clockwise direction, The halls in the detector assume predetermined different positions therein indicating the amount and direction ofturning ofthe goods. Thus. the detector 50 functions in the same manner as the detector 10.
