Child play puzzle

Abstract

A child play puzzle includes a set of pieces each defining a non-circular aperture therethrough. The child play puzzle also includes a base and a pole extending from the base along a pole axis. The pole sequentially receives each piece of the set of pieces with the pole extending through the aperture of each piece to form a stack of the pieces along the pole. The pole has multiple sections spaced along its length. Each section is of non-circular cross-section in a plane perpendicular to the pole axis. At least one of the sections is rotatable about the pole axis with respect to an adjacent one of the sections, such that moving a piece from about the rotatable section to about the adjacent section requires rotationally aligning the rotatable section with the adjacent section.

DETAILED DESCRIPTION

(8) Referring to FIG. 1, a child play puzzle 100 or puzzle set includes a base 102 and three play modules 104, 106, and 108 supported on base 102. Base 102 can be a rectangular board that is supportable on a horizontal surface 101. A first module 104 of the three play modules is a child play puzzle (e.g., a twist and pivot puzzle) that includes a first pole 110, a set of blocks 112 or sections coupled to pole 110, and a set of pieces 114 (e.g., removable pieces) that can be inserted in and stacked along pole 110. A second module 106 of the three play modules is a child play puzzle with a second pole 120, multiple sections 122 coupled to or extending from second pole 120, and a second set of removable pieces 124 that can be inserted in and stacked along second pole 120. Second play module 106 is spaced from first play module 104. A third play module 108 spaced from first play module 104 and second play module 106 includes a threaded pole 130 and a third set of removable pieces 134 that can be threadedly inserted in and stacked along pole 130. First play module 104 may feature a higher level of difficulty than second and third play modules.

(9) Referring also to FIG. 2, first pole 110 extends from board 102 along a first pole axis A, second pole 120 extends from board 102 along a pole axis B, and third pole 130 extends from board 102 along a pole axis C. Each of pole axes A, B, and C is perpendicular to a broad surface 103 of base 102. Thus, each pole 110, 120, 130 is attached to base 102 so as to extend vertically from base 102 and parallel with respect to each other, with base 102 supported on horizontal surface 101. In some implementations, the poles can extend horizontally from a vertical base or at an angle. The poles 110, 120, and 130 are spaced from each other to allow stacking of each set of pieces on their respective poles at the same time.

(10) As shown in FIG. 1, first pole 110 sequentially receives each piece 115 of set of pieces 114 with pole 110 extending through a non-circular aperture 116 of each piece 115 to form a stack of the pieces 115 along pole 110. As shown in FIG. 2 and as further described in detail below with respect to FIGS. 3-6, pole 110 has multiple sections or blocks 113 spaced or disposed along its length. Each block 113 has a non-circular cross-section (e.g., a non-circular periphery) in a plane perpendicular to first pole axis A. At least one block 113a is rotatable about first pole axis A with respect to an adjacent block 113b such that moving a piece 115 from about rotatable block 113a to about adjacent block 113b requires rotationally aligning rotatable block 113a with adjacent block 113b. Rotatable block 113 can be aligned before or after inserting piece 115. For example, when piece 115 is inserted in pole 110 and disposed about rotatable block 113a, aperture 116 of piece 115 engages the exterior surface of rotatable block 113a so that rotating the piece 115 rotates rotatable section 113a.

(11) As shown in FIG. 2, adjacent block 113b is rotationally fixed with respect to base 102. For example, with pole 110 rotationally fixed to base 102, adjacent block 113b (e.g., a rotationally fixed block) can be coupled to pole 110 to prevent rotation of adjacent block 113b with respect to pole 110 and base 102.

(12) Rotationally fixed block 113b is disposed between first rotatable block 113a and a second rotatable block 113c such that moving a piece from about first rotationally fixed block 113b to about second rotatable block 113c requires rotationally aligning second rotatable block 113c with first rotationally fixed block 113b.

(13) Second rotatable block 113c resides between rotationally fixed block 113b and a second adjacent block 113d (e.g., a second rotationally fixed block) that is disposed between base 102 and second rotatable block 113c. Similar to first rotationally fixed block 113b, second rotationally fixed block 113d is fixed against rotation with respect to base 102. Similar to rotatable block 113a, second rotatable block 113c rotates about pole axis A with respect to second rotationally fixed block 113d such that moving a piece 115 from about second rotatable block 113c to about second rotationally fixed block 113d (e.g., to reach base 102 with piece 115) requires rotationally aligning second rotatable block 113c with second rotationally fixed block 113d.

(14) First rotationally fixed block 113b is misaligned (e.g., arranged with offset corners) with respect to second rotationally fixed block 113d. Such arrangement requires that, when moving a piece 115 from about first rotationally fixed block 113b to about second rotationally fixed block 113d, one must first rotationally align second rotatable block 113c with rotationally fixed block 113b, and then, once piece 115 is about second rotatable block 113c, rotationally align second rotatable block 113c with second rotationally fixed block 113d.

(15) First rotatable block 113a and the second rotatable block 113c can be of a first color different than a color of the first and second rotationally fixed blocks 113b and 113d. Each block 113 of the set of blocks 112 can have a common cross-section shape and size. For example, each block 113 has a polygonal cross-section (e.g., square) of same or similar size. Each removable piece 115 defines a central non-circular aperture 116 therethrough. Non-circular aperture 116 of each piece 115 can be of a size and shape to match the common cross-section shape and size of blocks 113. Pieces 115 can have different overall widths, measured across their apertures 116.

(16) As shown in FIG. 1, second pole 120 sequentially receives each piece 125 of set of pieces 124 with second pole 120 extending through a non-circular aperture 126 of each piece 125 to form a stack of the pieces 125 along pole 120. As shown in FIG. 2, second pole 120 has multiple sections 122 spaced along its length, each including one or more ribs 123 (e.g., rounded ribs) extending away from second pole 120 and along second pole axis B. In other words, each section 122 has a non-circular cross-section in a plane perpendicular to second pole axis B. A first section 122a is rotationally misaligned with a second section 122b and is spaced from second section 122b to define a gap G therebetween. Such configuration requires that moving a piece 125 of the second set of pieces 124 from about the first section 122a to about the second section 122b requires rotationally aligning, at gap G, piece 125 (e.g., aligning the non-circular aperture of the piece 125) with second section 122b.

(17) Rounded ribs 123 are arranged in groups or sections 122 along the length of pole 120, with each rounded rib 123 of section 122 disposed at a different radial location of pole 120 and at the same vertical elevation along pole 120. Each section 122 can be rotationally fixed with respect to each other. For example, each section 122 can be rotationally fixed with respect to base 102 or, if rotatable about axis B, all sections 122 rotate together in the same direction.

(18) Third pole 130 sequentially receives each piece 135 of set of pieces 134 with third pole 120 extending through a circular aperture 136 of each piece 135 to form a stack of the pieces 134 along pole 130. Circular aperture 136 of each piece 135 is a threaded hole and third pole 130 has an exterior thread that threadedly receives each piece 135. As shown in FIG. 2, third set of pieces 134 includes pieces 135 of different sizes. For example, pieces 135 can have a circular shape, with each piece 135 having a different outer diameter.

(19) FIGS. 3-6 illustrate different elements of first child play module 104. FIG. 3 is a top view of first play module 104, featuring first block 113a of play module 104 rotationally coupled to pole 110. To insert piece 115 in pole 110 about first block 113a, the square-shaped aperture 116 of piece 115 is aligned with rotatable block 113a. The square cross-section of aperture 116 corresponds with the square cross-section perimeter of block 113a so that rotating piece 115 rotates block 113a. Similarly, piece 115 rotates the second rotatable block 113c (see FIG. 2).

(20) FIGS. 4 and 5 show the two blocks 113b and 113d that, when inserted or assembled in pole 110, are rotationally fixed to pole 110. For example, as shown in FIG. 4, first non-rotatable block 113b has one or more inwardly projecting shoulders 502 arranged along a diagonal axis D that extends between opposite vertices of block 113b. As shown in FIG. 5, second non-rotatable block 113d has one or more inwardly projecting shoulders 602 arranged in an axis E that extends symmetrically between two opposite sides of block 113d, across a center of block 113d. Such shoulders 502 and 602 engage a common groove of pole 110 to prevent blocks 113b and 113d from rotating with respect to pole 110.

(21) FIG. 6 shows pole 110 with a longitudinal groove 702 extending along a length of pole 110 from or near a base 710 of pole 110 to or near a top end 711 of pole 110. In some implementations, groove 702 can extend along a portion of pole 110 or be a discontinuous groove. Longitudinal groove 702 receives inwardly projecting shoulder 502 of first non-rotatable block 113b to prevent rotation of the block 113b with respect to pole 110. Longitudinal groove 702 also receives inwardly projecting shoulder 602 of second non-rotatable block 113d to prevent rotation of the block 113d with respect to pole 110. The arrangement of respective shoulders 502 and 602 is such that when blocks 113b and 113d are inserted in pole 110, the blocks are misaligned with respect to each other and a rotatable block 113c between the two non-rotatable blocks is always misaligned with at least one of the two non-rotatable blocks.

(22) To set up play module 104, a user may insert rotatable and non-rotatable blocks in an alternating arrangement as shown in FIG. 6, or place more than one rotatable block between two non-rotatable blocks. Additionally, before inserting pieces 115, a user (e.g., a parent) can rotate the rotatable blocks 113a and 113c to misalign the rotatable blocks with respect to the adjacent rotationally locked block.

(23) While a number of examples have been described for illustration purposes, the foregoing description is not intended to limit the scope of the invention, which is defined by the scope of the appended claims. There are and will be other examples and modifications within the scope of the following claims.
