• Hand manipulated logic puzzles having a plurality of segments connected for movement relative to one another into a desired alignment are well known in the art, and indeed, cubic forms of these types of puzzles have proven enormous popular.

• the logic puzzle 20 of the present invention comprises twelve spanning members 24, which are arranged so as to define a central locus X and six subordinate locii Y equally circumferentially-spaced thereabout.
• the subordinate locii Y collectively define three axes A, normal to one another and intersecting at the central locus X, with each of said subordinate locii Y being intersected by a respective one of said axes A.
• a respective four of said spanning members 24 extend, respectively, from each of the subordinate locii Y to each of the subordinate locii Y circumferentially adjacent thereto.
• the present invention also comprises rotational means, designated by general reference numeral 50 and described more fully in the following paragraphs, for enabling, when said spanning members 24 are in the operative configuration, selective relative rotation by manual manipulation of a selected group of four contiguous spanning members 24 selected from said twelve spanning members 24 and extending from a selected one of said subordinate locii Y about the respective axis A intersecting said selected one of the subordinate locii Y.
• rotation is best illustrated in Figures 1 and 2, with Figure 1 showing the spanning members 24 in their operative configuration, and Figure 2 showing a selected group of four contiguous spanning members 24, namely, the uppermost four of said spanning members 24, rotated relative to the remaining spanning members about the vertical axis A.
• the spanning members 24 are each seen, inter alia, in Figure 1 to be substantially arcuate, thereby to collectively take the shape of three open rings, normal to one another and surrounding the central locus X when in said operative configuration.
• the contemplated shape is preferable from the standpoint of aesthetics.
• the spanning members 24 need not necessarily be arcuate, and indeed, may take any variety of shapes, having equally satisfactory utility, and accordingly, the present invention is expressly not to be limited to embodiments thereof including spanning members 24 arcuate in shape .
• the rotational means 50 preferably comprises a pair of substantially arcuate channels 24 ' formed in each spanning member 24 on opposite sides of a respective medial plane 52 which is defined by the axes A intersecting the respective subordinate locii Y between which said each spanning member Y extends. Said medial plane 52 is illustrated in Figure 12.
• the spanning members 24 preferably each comprises an inner arcuate flange portion 28, a concentric outer arcuate flange portion 30 and a curved web portion 32 rigidly extending between and connecting said inner arcuate flange portion 28 and said outer arcuate flange portion 30.
• Each main body member 22 comprises three slider arms 38 and three junction portions 54, said slider arms 38 being rigidly interconnected in end-to-end, normal relation to one another and separated by respective junction portions 54.
• the slider arms 38 are shaped complementary to the arcuate channels 24' and, when said spanning members 24 are in their operative configuration, are each mounted within a respective one of the arcuate channels 24' in inter-fitting, frictional relation for sliding, circumferential movement relative thereto, thereby to slidably attach said main body members to said spanning members for selective relative rotation therewith.
• the spanning members 24 are each formed with free end portions
• each slider arm 38 is provided with a substantially planar, arcuate major surface 56, adjacent to the web portion 32 of the spanning member 24 having the arcuate channel 24 ' within which said slider arm 38 is slidably mounted when the spanning members 24 are in the operative configuration, and an opposed bullnosed, arcuate side surfaces 58, best illustrated in Figures 3, 4 and 5.
• This profile of the slider arms 38 is not strictly necessary, as other profiles will have similar utility, but is advantageous, in that it enables the components of the logic puzzle 20 to be press-fit together during assembly, while retaining sufficient rigidity for normal use. It will be evident to persons skilled in the art that, in logic puzzles 20 constructed in accordance with the foregoing structure, it is possible for opposing groups of four of said twelve spanning members 24, that is, all of the spanning members 24 which extend from the pair of subordinate locii Y intersected by any given axis A, to rotate contemporaneously about said axis A relative to the remaining spanning members 24.
• This feature of the foregoing structure does not add significant utility to the logic puzzle 20, as sequential rotation of said opposing groups would have the same effect upon the alignment of the puzzle elements, and moreover, intentional contemporaneous manipulation of said opposing groups requires manual dexterity well beyond the ability of most users.
• Such feature does, however, pose some difficulties in operation, particularly in that it enables inadvertent partial rotation of a group of contiguous spanning members 24 about any given axis A, particularly in relation to users having limited manual dexterity, such as children and the infirm, and could go unnoticed, potentially resulting in damage to the logic puzzle 20 if rotation about another of the axes A was attempted.
• a locking means 76 for exclusively enabling relative rotation, when said selected group of four contiguous spanning members 24 have undergone said selective relative rotation otherwise than to the operative configuration, of said selected group of four contiguous spanning members 24 about the respective axis A intersecting the selected one of the subordinate locii Y.

• a respective detent member 62 associated with each spanning member 24 is also provided, as are mounting means 64 for operative mounting of each detent member 62 on the respective slider arm 38 associated therewith, such that, as illustrated in Figure 13A, each detent member 62 is aligned with the socket means 60 of the slider arms 38 respectively mounted within the pair of arcuate channels 24 ' formed on the spanning member 24 to which said each detent member 62 is operatively attached when said spanning members 24 are in said operative configuration.
• the slider arms 38 define a first slider arm 66 associated with said each detent member 62 and a second slider arm 68 associated with said each detent member 62.
• the mounting means 64 is adapted such that, upon said sliding, circumferential movement of the first slider arm 66 associated with said each detent member 62, said each detent member 62 is displaced from the socket means 60 of the first slider arm 66 associated therewith and caused to lockingly engage the socket means 60 of the second slider arm 68 associated with said each detent member 62, as illustrated in Figure 13B.
• the mounting means 64 is further adapted to disengage each said detent member 62 from said socket means 60 of said second slider arms 68 associated with said each detent member 62 when said spanning members 24 are in said operative configuration.
• the spanning members 24 are each constructed from a strong, but somewhat flexible plastic material, such as polyethylene, or nylon such that the mounting means 64 comprises a respective tab member 64 flexibly, resiliently attached to and integrally formed with each spanning member 24, to which respective tab member 64 the detent member 62 associated with said each spanning member 24 is rigidly attached and integrally formed therewith.
• the mounting means 64 comprises a respective tab member 64 flexibly, resiliently attached to and integrally formed with each spanning member 24, to which respective tab member 64 the detent member 62 associated with said each spanning member 24 is rigidly attached and integrally formed therewith.
• any other suitable mounting means 64 could be employed.
• Each cap member 26 is also preferably provided, each of said cap members 26 being positioned at a respective one of the subordinate locii Y such that a respective four of said twelve spanning members 24 extend, respectively, from said each cap member 26 to each of the cap members 26 circumferentially adjacent thereto.
• Each cap member 26 comprises an upper portion 26A overlying the spanning members 24 extending therefrom, a lower portion 26B underlying the spanning members 24 extending therefrom, and a pin member 26C extending between and rigidly connecting said upper portion 26A and said lower portion 26B.

• the pin member 26C may be rigidly attached to the upper portion 26A and the lower portion 26B by any conventional manner, for example, by the use of suitable adhesives.
