a novel amusement device or puzzle constructed in accordance with this invention is generally designated by the reference numeral 10 , and is depicted as wood head of a golf club , such as a driver or a fairway wood . however , though the amusement device or puzzle 10 is preferably a golf head in external appearance and configuration , other configurations are contemplated , such as the fishing lure and heart - shaped configurations mentioned earlier herein . the amusement device 10 is defined by a plurality of plates including a top plate 11 , a bottom or base plate 12 , a first upstanding end plate or toe plate 13 spaced from a second upstanding end plate or heel plate 14 and a plurality of intermediate plates 15 through 18 ( fig1 ). an uppermost one of the intermediate plates 15 carries in spaced generally parallel depending relationship thereto a front plate or face plate 20 ( fig8 and 12 ) and a rear plate 21 . the intermediate plates 16 through 18 have circular right - cylindrical bores or apertures 26 , 27 and 28 , respectively ( fig4 , 8 and 12 ) which collectively define a generally cylindrical &# 34 ; secret &# 34 ; compartment or chambers in which is housed one or more articles a , which in the present embodiment of the amusement device 10 is a golf ball a . preferably , the plates 11 , 12 , 13 , 14 , 16 , 17 and 18 are each formed from a single piece of wood or each is formed from a plurality of pieces of similar wood laminated together , and in either case the plates 11 , 12 , 13 , 14 , 16 , 17 and 18 are carved or machined to the appropriate golf head contour or configuration . the plate 15 is also a single piece of wood or a plurality of pieces of wood laminated together , and glued or bonded thereto are the rear plate 21 and the front plate 20 ( fig8 ). however , the front plate 20 is preferably formed from lighter and darker wood to provide the appearance of a typical golf club &# 34 ; face ,&# 34 ; and in this regard two vertical wall portions 22 , 23 of the face plate 20 are formed from very light wood and sandwiched therebetween is another vertical wall portion 24 formed of a very dark or reddish appearing wood , such as mahogany . by including a plurality of vertically spaced horizontally disposed grooves 25 in the wall portions 22 through 24 , the face plate or front plate of the amusement device 10 takes on the appearance of the typical &# 34 ; face &# 34 ; of a golf driver or fairway wood head . however , while in the preferred embodiment of the amusement device 10 , the various components thus far described and others to be described hereafter are preferably constructed from wood to lend an authentic appearance to the amusement device 10 , these components can be constructed from polymeric or copolymeric synthetic plastic material appropriately injection molded or from compression molded materials , such as admixtures of shells and adhesives which are conventionally utilized to manufacture life - like mock wood statutes . irrespective of the particular materials or methods of manufacture , the top plate 11 includes an upper contoured surface 30 , a lower flat surface 31 and a generally truncated upwardly converging frusto - conical neck 32 terminating in a flat annular surface or face 33 . a cylindrical bore 34 passes completely through the neck 32 and is in alignment with an upwardly opening blind bore 35 ( fig4 and 6 ) of the second end plate or heel plate 14 when the top plate 11 is in the position illustrated in fig1 and 4 of the drawings . however , the top plate 11 can be pivoted from the position shown in fig1 and 4 to the position thereof shown in fig6 and 10 , and when thus positioned , the bores 34 , 35 are not in alignment . means generally designated by the reference numeral 40 are provided for pivoting the top plate 11 relative to the remaining plates . the pivotally mounting means 40 includes a pivot pin or stem 41 and a cylindrical bore or opening 42 in the heel plate 14 opening through an upper relatively flat surface 43 thereof ( see fig4 and 11 ). the pivot pin or stem 41 includes a reduced medial portion 44 merging with an enlarged cylindrical head 45 having an annular abutment ledge or shoulder 46 ( fig4 and 11 ) which functions in a manner and for a purpose to be described hereinafter . a hosel portion or element 50 forms a frusto - conical continuation of the neck 32 of the top plate 11 but is a separate element formed of wood and has - wound thereupon thread t to provide the hosel portion with the appearance of an authentic golf club hosel . the hosel portion 50 includes a planar circular end 51 and a flat surface 52 ( fig4 ) through which opens a blind bore 53 into which is inserted and cemented a pin 54 . the pin 54 cooperates with the blind bore 35 of the heel plate 14 to define means for preventing the top plate 11 from pivoting about the axis of the stem 41 relative to the remaining plates when the pin 54 is seated in the blind bore 35 . however , when the hosel portion 50 is pulled upwardly and removed , as shown in fig9 the end of the pin 54 is retracted from the blind bore 35 of the heel plate 14 and the top plate 11 can be pivoted to the position shown in fig9 to expose the uppermost intermediate plate 15 and the end plate or toe plate 13 , particularly flat coplanar respective surfaces 57 , 58 thereof . the surfaces 57 , 58 are in intimate contacting relationship with the surface 31 of the top plate 11 when the top plate 11 is in the &# 34 ; locked &# 34 ; position of fig1 and 2 which virtually precludes an observer from noticing any significant differences in appearance or line of demarcation between the top plate 11 and the end plates 13 , 14 to thereby preclude rapid solving of the &# 34 ; puzzle &# 34 ; associated with disassembling the amusement device 10 and locating the article a within the secret compartment s . means 60 ( fig3 and 9 through 12 ) define dovetail connecting means between the first end plate or toe plate 13 and each of the intermediate plates 15 through 18 . the means 60 effects selective coupling and uncoupling of the toe plate 13 relative to the intermediate plates 15 through 18 simply through an upward or downward sliding motion relative therebetween ,, as is best illustrated in fig1 and indicated by the double headed arrows ( unnumbered ) associated with the toe plate 13 . the dovetail connecting or coupling means 60 is preferably defined by a dovetail slot 61 ( fig1 ) running the full length of the toe plate 13 between the surface 58 and a lowermost flat surface 62 ( fig4 ). each of the intermediate plates 15 through 18 is provided with a corresponding dovetail innerlocking portion or tongue designated by the reference numerals 63 through 66 , respectively . also , the intermediate plates 15 through 18 include a set of aligned dovetail slots 73 through 76 , respectively ( fig3 and 12 ) which correspond in shape and configuration to a dovetail portion or tongue 77 of the heel plate 14 . thus , the dovetail tongues 63 through 66 and 77 intimately engage with and slide relative to the dovetail slots 61 and 73 through 76 , respectively , to effectively selectively couple and uncouple the toe plate 13 relative to the intermediate plates 15 through 18 , as is best illustrated in the comparative illustrations of fig9 and 10 of the drawings . the purpose of removing the toe plate 13 is to facilitate the total removal of the top plate 11 , as shown in fig1 . in order to accomplish the latter , the intermediate plate 17 must be shifted from a locked position ( fig4 ) to an unlocked position ( fig6 ) and the structure for accomplishing the latter is best illustrated in fig4 through 7 of the drawings . the intermediate plate 17 includes a reduced flat projecting portion 80 ( fig5 and 7 ) which is received in a chamber 81 of the heel plate 14 which is of a generally polygonal configuration ( fig5 ) and opens to the left , as viewed in fig5 . the chamber 81 is closed at its top by a wall 82 and its bottom by a wall 83 ( fig4 ). a slot 84 formed in the projecting portion 80 opens to the right , as viewed in fig4 and 7 , and is of a width slightly greater than that of the diameter of the head 45 of the pivot stem 41 carried by the top plate 11 . when the intermediate plate 17 is in its locked position with the projecting portion 80 thereof seated fully within the chamber 81 , a lower abutment surface or undersurface 89 ( fig4 ) of the projecting portion 80 overlies the abutment ledge 46 of the head 45 ( fig5 ) and prevents any upward force applied to the top plate 11 from moving the latter in an upward direction . however , if the intermediate plate 17 is shifted to the left , as indicated in fig6 and 7 , the undersurface 89 of the intermediate plate 17 no longer overlies the head 45 ( fig7 ) of the stem 41 and the top plate 11 can be lifted vertically upwardly in the manner illustrated in fig1 to disassemble the top plate 11 which permits the subsequent removal of the uppermost intermediate plate 15 and the plates 20 , 21 carry thereby , as will be apparent more fully hereinafter . however , without removing the top plate 11 , the uppermost intermediate plate 15 cannot be removed because no matter in which position the top plate 11 is rotated , a portion of the top plate 11 will always overlie the uppermost intermediate plate 15 , as is clearly illustrated in fig6 and 10 of the drawings . the intermediate plates 16 , 18 each have projecting portions 86 , 88 , respectively , identical in size and configuration to the projecting portion 80 . furthermore , each of the projecting portions 86 , 88 includes relatively large circular slot means or aperture means ( unnumbered ) which will allow the head 45 to at all times pass therethrough freely without interference . therefore , the abutment ledge 46 of the head 45 and the lower abutment surface 89 of the projecting portion 80 of the intermediate plate 17 constitute the means for selectively holding these plates assembled when interlocked , as shown in fig5 and for effecting separation thereof when released in the manner illustrated in fig7 . preferably the intermediate plates 16 and 18 are held immobilized after the toe plate 13 has been removed . this is accomplished by simply bonding / gluing the lowermost intermediate plate 18 to the base plate 12 . in order to immobilize the intermediate plate 16 after the removal of the toe plate 13 , a downwardly projecting pin or stem 90 ( fig1 ) of the uppermost intermediate plate 15 is received in a bore 91 ( fig1 ) of the intermediate plate 16 . as can be best visualized with respect to fig1 and 12 , once the pin 90 is in the bore 91 ( fig1 ) and the components are in the position shown in fig1 , a leftward pull on any of the dovetail portions 65 through 66 will result only in the leftward movement of the intermediate plate 17 because the lowermost intermediate plate 18 is adhesively secured to the base plate 12 , and the intermediate plates 15 , 16 are interlocked together by the pin or stem 90 and the bore 91 and the stem 41 in the circular bore ( unnumbered ) of the projecting portion 86 of the intermediate plates 16 . however , once the intermediate plate 17 is shifted to the left ( fig6 ) to create : the unlocking heretofore described relative to fig7 the top plate 11 can be removed followed by an upward lifting of the uppermost plate 15 , as shown in fig7 which carries therewith the face plate 20 and the rear plate 21 to expose the secret compartment s and the article / golf ball a therein . at this point ( fig1 ) the golf ball a can be removed from the secret compartment s and , if desired , the intermediate plates 16 , 17 can be removed , as also might be the heel plate 14 . at this point the amusement device 10 is in eight separate pieces , namely , ( 1 ) the base plate 15 and the lowermost intermediate plate 18 bonded thereto , ( 2 ) the heel plate 14 , ( 3 ) the intermediate plate 17 , ( 4 ) the intermediate plate 16 , ( 5 ) the intermediate plate 15 carrying the plates 21 , 21 , ( 6 ) the toe plate 13 , ( 7 ) the top plate 11 and ( 8 ) the hosel portion 50 . in order to reassemble the eight components , the heel plate 14 is slipped upon the base plate 15 with the projecting portion 81 of the lowermost intermediate plate 18 being received in the chamber 81 , after which the projecting portions 80 , 86 of the intermediate plates 17 , 16 , respectively , are inserted into the chamber 81 . the golf ball a is inserted in the chamber s , and the plate 15 is descended from the position shown in fig1 to the position shown in fig1 . the dovetail portion 65 of the intermediate plate 17 is pulled slightly to the , left , as shown in fig6 and 11 , and the stem 41 is inserted into the bore 42 of the end plate 14 until the components reach the position shown in fig6 after which the intermediate plate 17 is shifted to the right ( fig4 ) blocking the head 45 of the stem 41 beneath the projecting portion 80 of the intermediate plate 17 . the toe plate 13 is then slid downwardly from the position shown in fig1 to that shown in fig9 after which the top plate 11 is pivoted to its closed position ( fig1 through 3 ) and locked therein by positioning the hosel portion 30 with its stem 54 in the blind bore 35 to prevent rotation of the top plate 11 . although a preferred embodiment of the invention has been specifically illustrated and described herein , it is to be understood that minor variations may be made in the apparatus without departing from the spirit and scope of the invention , as defined the appended claims .
a novel amusement device is constructed of a plurality of individual plates , and internally thereof the plates define a secret chamber within which one or more articles can be housed . the various plates are constructed to be assembled through a specific sequence of steps , while a reverse sequence of steps results in the disassembly thereof which essentially reveals the secret compartment of the amusement device and the article contained therein .
