(72) Reference is additionally made to FIGS. 2A, 2B, 2C, 2D, 2E, and 2F, which are, respectively, an exploded view illustration, a perspective view illustration, and front, side, back, and top view planar illustrations of cutting subassembly 170 according to an embodiment of the teachings herein.

(73) As seen, cutting subassembly 170 includes a housing 172 arranged about a longitudinal axis 173 (see FIG. 2D) and having a cowl portion 174 terminating at a distal lip 176, the cowl portion adapted to be rotatably disposed within indentation 150. Extending forward from cowl portion 174, is a main body portion 178, adapted to have a disc-shaped blade 180 seated in a dedicated slot 182 therein. Slot 182 is formed in the circumference of main body portion 178. Blade 180 includes a central bore 184, which is adapted to be aligned with an axial bore 186 formed in main body portion, and to be fixedly held within slot 182 by a screw or pin 188, extending through axial bore 186 and through central bore 184 of blade 180. A diameter of blade 180 is smaller than the radius of main body portion 178, such that when the blade is held within the main body portion, the blade is disposed above the center point of the main body portion, as seen clearly in FIG. 2C.

(74) Main body portion 178 further has a second slot 190, extending through the entire length of the body portion and through most of the diameter thereof, such that an end of blade 180 extends into slot 190, as seen clearly in FIG. 2C. Slot 190 has extending therefrom a tube-receiving recess 192, which extends away from blade 180, between a pair of wheels 194 held by pins 196. As explained in further detail hereinbelow, in use, a tube to be cut is slid into main body portion 178 via recess 192, such that rotation of the housing 172 together with blade 180 results in cutting of the tube.

(75) Main body portion 178 further includes two protrusions 197, extending substantially tangentially to the circumference of the main body portion, each protrusion being disposed on a different end of slot 190 and including a bore 198. A tightening pin or screw 199 is adapted to extend through bores 198 of protrusions 197, and, in use, to apply pressure to the protrusions thereby to reduce the width of slot 190 and to force blade 180 to apply suitable pressure to the tube being cut, as explained in detail hereinbelow.

(76) Reference is now made to FIGS. 3A, 3B, 3C, 3D, 3E, and 3F, which are perspective view illustrations of steps of cutting a tube using the tube cutting subassembly forming part of the device of FIGS. 1A to 1E.

(77) As seen in FIG. 3A, a hollow elongate tube 300 is disposed outside of device 100, and is aligned with recess 192 of slot 190 of the cutting subassembly 170.

(78) The elongate tube 300 may be formed of any suitable material, and is typically formed of metal, such as aluminum, or of a pliable plastic.

(79) In some embodiments, the exterior diameter of the elongate tube is in the range of 3 mm to 5 mm.

(80) In some embodiments, the diameter of the hollow of the elongate tube is in the range of 2 mm to 4 mm.

(81) In some embodiments, the thickness of the wall of the elongate tube is in the range of 0.25 mm to 1 mm.

(82) In some embodiments, at step 3A, prior to insertion of the tube into the device 100, the user may anchor the device to a working surface, such as a table, using anchoring elements 112, substantially as described hereinabove.

(83) As seen, the tip of anchoring screw 160 is raised above protrusions 122 and slot 124, and the cutting subassembly is oriented such that the head of tightening screw 199 is directed downward, away from top surface 103.

(84) In FIG. 3B, the elongate tube 300 has been inserted, via recess 192 of slot 190 and the hollow of the cowl of cutting subassembly 170 into slot 124 between protrusions 122, to a desired degree. In some embodiments, the user may use the indications, marked on protrusions 122, to know the length of the tube 300 disposed within slot 124, between the location of blade 180 and the end of the tube. As seen, the orientation of anchoring screw 160, of cutting subassembly 170, and of tightening screw 199, remains unchanged relative to FIG. 3A.

(85) In FIG. 3C, the user has rotated anchoring screw 160 to engage the section of elongate tube 300 disposed within slot 124, and to anchor the elongate tube 300 in position prior to cutting thereof. In this arrangement, blade 180 engages tube 300.

(86) Once the elongate tube 300 is anchored, the user rotates cutting subassembly 170, within indentation 150 and relative to the remainder of device 100 and to tube 300, as illustrated in FIGS. 3D and 3E. Each of FIGS. 3D and 3E which shows a 90-degree rotation of cutting subassembly 170. Rotation of cutting subassembly 170 causes corresponding rotation of blade 180 about tube 300. Due to the engagement of blade 180 with tube 300, rotation of cutting subassembly 170 results in partial cutting of the tube.

(87) As the user continues to rotate the cutting subassembly, the blade cuts deeper and deeper into the tube, until the tube is fully cut into a first portion 300a anchored within device 100, and a second portion 300b outside of the device, as illustrated in FIG. 3F.

(88) In some embodiments, following one or more full rotations of cutting assembly 170, the user may twist and tighten screw 199, causing protrusions 197 to become closer to each other, thereby increasing the pressure applied by the blade to the tube, to facilitate cutting of more internal portions of the tube. This is particularly useful when the tube is formed of a relatively thick material.

(89) Following cutting of the tube, the user may remove the cut tube portion from slot 124 by releasing anchoring screw 160 and sliding the cut tube portion out of slot 124 away from cutting subassembly 170, or through cutting subassembly 170.

(90) In some embodiments, the pressure applied by blade 180 to tube 300 causes deformation of the shape of the tube at the cutting point. In some such embodiments, device 100 may further include a re-shaping protrusion, onto which cut tube 300a may be placed in order to return the end thereof to circular shape.

(91) Reference is now made to FIGS. 3G, 3H, and 3I, which are perspective view illustrations of steps of bending a tube 310, which may be a tube previously cut as described with respect to FIGS. 3A to 3F, or a complete tube as provided by a manufacturer or retailer, using a tube bending subassembly 130 forming part of the device 100.

(92) As seen in FIG. 3G, the device 100 is prepared for bending of tube 310, by rotating handle 136 from being parallel to the protrusions 122, to being perpendicular thereto. The tube 310 is not yet placed in the device 100.

(93) At a next step, shown in FIG. 3H, tube 310 is inserted into the bending assembly 130, between disc shaped base 132 and second pin 148, such that the tube 310 engages groove 134 and is disposed between the arms of receiving portion 140.

(94) FIG. 3I shows the next step of the bending process, in which handle 136 is rotated relative to main body 102 and relative to disc shaped base 132. The pin 148 rotates together with handle 136, and pushes the tube 310 to bend about base 132. The degree of bending of the tube 310 may be controlled by the angle to which the user rotates the handle 136. Rotating the handle 45 degrees, will result in the tube 310 being bent 45 degrees from the initial state (straight line or 180-degree angle), and thus the tube will have an angle of 135 degrees. Rotating the handle 120 degrees, will result in the tube 310 being bent 120 degrees from its initial, straight line, state, and in the tube having an angle of 60 degrees. Rotating the handle 90 degrees, as illustrated, results in the tube 310 having a bend of 90 degrees.

(95) When using the tubes and connectors described herein, typically the user prepares multiple hollow elongate tubes, by cutting and/or bending the tubes to be in a desired configuration, for construction of a structure using the construction toy of the present invention.

(130) It is appreciated that while FIGS. 11A and 11B illustrate the connection between a snap-fit end connector and a specific supporting connector, the process of connecting a snap-fit connection portion to a sliding connection portion is relevant for any pair of connectors including these connection components, regardless of the number or type of prongs such connectors include.

(131) FIGS. 12A and 12B are, respectively, perspective view illustrations of a second exemplary use of the female pivoting end connector 460 of FIGS. 7A to 7C according to an embodiment of the disclosed technology. As seen in FIG. 12A, female pivoting end connector 460 is disposed adjacent, and is aligned with, male pivoting portion 534 of supporting connector 530 (see also FIGS. 11A and 11B).

(132) As seen in FIG. 12B, connectors 460 and 530 are connected to one another such that longitudinal protrusion 540 of male pivoting portion 534 (similar to longitudinal protrusion 448 of FIGS. 6A to 6C) is disposed within gap 470 of female pivoting end connector 460. Protrusions 472 are rotatably disposed within corresponding recesses 542 of male pivoting protrusion 534 (similar to recesses 452 of FIGS. 6A to 6C). In this arrangement, connectors 460 and 530 can pivot relative to one another about an axis extending through protrusions 472 and recesses 542, so as to change the angular orientation between prong 467 and sliding connector portion 536.

(133) It is appreciated that while FIGS. 12A and 12B illustrate the connection between a female pivoting end connector and a specific supporting connector, the process of connecting male and female pivoting connection portions to one another is relevant for any pair of connectors including these connection components, regardless of the number or type of prongs such connectors include.

(134) Reference is now made to FIGS. 13A and 13B, which are, respectively, a perspective view illustration and a front view planar illustration of an extending connector 550 according to an embodiment of the disclosed technology. As seen, extending connector 550 includes a base 552 having a first surface 554 and a second surface 556. Prongs 557 and 558, both similar to prong 407 of FIGS. 4A and 4B, extend longitudinally outwardly from first surface 554 and second surface 556 respectively. Extending connector 550 is suitable for extending the length of a tube, by connection of a first tube to prong 557 and a second tube to prong 558, such that the resulting tube has the cumulative length of the first and second tubes.

(135) In some embodiments, not explicitly shown, one or both of prongs 557 and 558 may be replaced by a tubular prong, similar to or identical to tubular prong 437 of FIGS. 5C to 5E, or to tubular prong 417 of FIGS. 4C to 4E.

(136) FIGS. 14A, 14B, and 14C, are, respectively, a perspective view illustration, a side view planar illustration, and a front view planar illustration of a three-directional sliding connector 560 according to an embodiment of the disclosed technology. As seen, three directional sliding connector 560 includes a triangular base 562, here illustrated as an equilateral triangle, extending along a longitudinal axis 563, and having three side surfaces 564 as well as front and back surfaces 566. Each of side surfaces 564 has extending therefrom a prong 567, all similar to prong 407 of FIGS. 4A and 4B.

(137) Connector 560 further includes a longitudinal bore 568 extending longitudinally through base 562, similar to bore 490 of FIGS. 8A to 8C. Bore 568 is adapted for a tube to be slidably placed therethrough, and/or for snap-fit connection of a suitable connector thereto, such as connector 500 of FIGS. 9A to 9C, substantially as described with respect to FIGS. 11A and 11B.

(138) Reference is now additionally made to FIGS. 14D, 14E, and 14F, which are, respectively, a perspective view illustration, a side view planar illustration, and a front view planar illustration of a three-directional sliding connector 560′ according to another embodiment of the disclosed technology. Three-directional sliding connector 560′ is substantially similar to three-dimensional sliding connector 560, with each of prongs 567 being replaced by a tubular prong 567′, substantially similar to tubular prong 437 of FIGS. 5C to 5E, or to tubular prong 417 of FIGS. 4C to 4E. In some embodiments (not explicitly shown), only some of prongs 567 may be replaced by tubular prongs 567′, such that the resulting three-dimensional sliding connector may have a mixture of prongs and tubular prongs extending therefrom.

(139) When a tube is connected to each of prongs 567 or 567′, in the orientation of connector 560, an angle of 120 degrees is formed between each two adjacent tubes, and all the tube connections lie in a single plane. If a fourth tube is slidably disposed in bore 568, it has a 90-degree angle to each of the tubes on prongs 567 or in tubular prongs 567′, and is perpendicular to the plane of prongs 567/567′. However, it is appreciated that base 562 may be arranged differently, such that it is not an equilateral triangle, or the prongs are not disposed in a single plane, in which case the angular arrangement of prongs 567/567′ would be different. Additionally, in some embodiments, bore 568 may be obviated, such that the connector may only be used for connection of three tubes in a single plane.

(140) FIGS. 15A, 15B, and 15C, are, respectively, a perspective view illustration, a side view planar illustration, and a front view planar illustration of a four-directional sliding connector 570 according to an embodiment of the disclosed technology. As seen, four-directional sliding connector 570 includes a quadrilateral base 572, here illustrated as a square, extending along a longitudinal axis 573, and having four side surfaces 574 as well as front and back surfaces 576. Each of side surfaces 574 has extending therefrom a prong 577, all similar to prong 407 of FIGS. 4A and 4B. In some embodiments, some or all of prongs 577 may be replaced by tubular prongs, each similar to or identical to tubular prong 437 of FIGS. 5C to 5E, or to tubular prong 417 of FIGS. 4C to 4E.

(141) Connector 570 further includes a longitudinal bore 578 extending longitudinally through base 572, similar to bore 490 of FIGS. 8A to 8C. Bore 578 is adapted for a tube to be slidably placed therethrough, and/or for snap-fit connection of a suitable connector thereto, such as connector 500 of FIGS. 9A to 9C, substantially as described with respect to FIGS. 1 Back to patents
