[0095] Now for reference Figure 1A , 1B 1C, 1D, and 1E are exploded views, perspective views, top plans, front plans, and side plans, respectively, of device 100 for cutting and bending hollow elongated tubes for constructing toys. This device is an embodiment according to the teachings herein. Device 100 is sized and configured to be suitable for use by children in their home environment. In some embodiments, device 100 is sized and configured for handheld use.

[0096] As shown in the figure, the device 100 includes a body 102, which includes a top surface 103 and partial sidewalls 104, each sidewall terminating at a base portion 106. Two of the sidewalls 104 may include a plurality of recesses 108, which are adapted to the user's fingers and allow the user to comfortably hold the device in their hand.

[0097] The sidewall 104 may also include apertures 110, each aperture 110 adapted to receive a clamping sub-assembly 112 for clamping the device 102 onto a surface of a table or any other workstation, such as a counter or workbench. In some embodiments, the clamping sub-assembly 112 includes a bent metal rod 114 having a horizontal portion substantially parallel to the top surface 103 of the device 100 and a vertical portion substantially parallel to the sidewall 104 of the device. An anchoring element 116 having an anchoring surface 118 and a locking screw 120 are slidably mounted on the vertical portion of the rod 114.

[0098] In use, the device 100 is placed on a table such that the base portion 106 engages with the upper surface of the table. The horizontal portion of the rod 114 is seated within the aperture 110 and extends beyond the edge of the table, while the vertical portion extends downward along the edge of the table. The anchoring element 116 slides upward toward the table until its anchoring surface 118 engages with the lower surface of the table. The anchoring element 116 is then locked in place on the rod 114 by a locking screw 120, thereby ensuring continuous engagement with the worktable.

[0099] Assembled on the top surface 103 is a measuring subassembly for measuring the desired dimensions of the hollow elongated tube. The measuring subassembly includes a pair of elongated protrusions 122 extending outward and upward from the top surface 103 and forming an elongated channel 124 between them. The channel 124 is sized and configured to receive the hollow elongated tube 200, as explained in further detail below. Each protrusion 122 is typically marked with multiple length indicators, for example, by etching, printing, or embossing the tip of the protrusion. The length indicators can use any suitable unit of measurement, and multiple units of measurement can be used, such as inches and centimeters.

[0100] A cylindrical protrusion 126 extends upward and outward from the protrusion 122. The protrusion 126 is adapted to connect with the cutting sub-assembly.

[0101] Mounted on surface 103 is a bending sub-assembly 130 adapted to bend a cut hollow elongated tube to a desired angular orientation. The bending sub-assembly includes a disc-shaped base 132 with a central aperture 133 and a circumferential groove 134 adapted to receive the (cut) hollow elongated tube therein. The radius of the groove 134 controls the radius of the bend formed in the tube. A user-gripable handle 136 has a gripping portion 138 and a receiving portion 140 including two flat surfaces, each including a first aperture 142 and at least a second aperture 144. The base 132 is arranged between the flat surfaces of the receiving portion 140 such that the central aperture 133 is aligned with its first aperture 142. A first pin 146 extends through apertures 133 and 142, such that the base 132 is fixed relative to the first pin 146, while the handle 136 is rotatable relative to the pin 146. The second pin 148 is disposed within the second orifice 144 and is fixed relative to the handle 136. The use of the bending sub-assembly 130 is discussed below. Figures 3G to 3I To describe in more detail.

[0102] At its lateral end, the top surface 103 includes a semi-cylindrical recess 150 surrounded by a pair of protrusions 152. The recess 150 is adapted to receive a cutting sub-assembly 170, as described in further detail below. An anchoring element 154 is adapted to be securely attached to the protrusions 152 and to hold the cutting sub-assembly 170 to the body 102, while allowing the cutting sub-assembly to rotate relative to the body 102 within the recess 150, as explained herein. Anchoring element 156 also includes a threaded orifice 158 adapted to receive a correspondingly threaded anchoring screw 160 therein. Anchoring element 156 is adapted to be arranged such that the orifice 158 and the anchoring screw 160 are positioned above the elongated channel 124, such that one end of the anchoring screw 160 is adapted to engage and anchor or secure the position of the hollow elongated tube 200 during cutting.

[0103] For further reference Figure 2A , 2B 2C, 2D, 2E, and 2F are exploded views, perspective views, front view, side view, rear view, and top view of a cutting sub-assembly 170 according to an embodiment of the teachings herein.

[0104] As can be seen, the cutting sub-assembly 170 includes a housing 172, which surrounds a longitudinal axis 173 (see...). Figure 2D A fairing portion 174 is arranged and terminates at a distal lip 176, the fairing portion being adapted to be rotatably disposed within a recess 150. Extending forward from the fairing portion 174 is a body portion 178 adapted to house a disc-shaped blade 180 seated in a dedicated slot 182. The slot 182 is formed in the circumference of the body portion 178. The blade 180 includes a central aperture 184 adapted to align with an axial aperture 186 formed in the body portion and adapted to be securely held within the slot 182 by a screw or pin 188 extending through the axial aperture 186 and the central aperture 184 of the blade 180. The diameter of the blade 180 is smaller than the radius of the body portion 178, such that when the blade is held within the body portion, the blade is positioned above the center point of the body portion, as... Figure 2C It is clearly visible in the middle.

[0105] The main body portion 178 also has a second slot 190 that extends through the entire length of the main body portion and through most of its diameter, such that one end of the blade 180 extends into the slot 190, as... Figure 2C Clearly visible in the image. The tube receiving recess 192 extends from the slot 190 between a pair of wheels 194 held by pins 196 and extends away from the blade 180. As explained in further detail below, in use, the tube to be cut slides into the body portion 178 via the recess 192, such that rotation of the housing 172 together with the blade 180 results in cutting of the tube.

[0106] The main body 178 also includes two protrusions 197 that extend substantially tangentially to the circumference of the main body. Each protrusion is located at a different end of the slot 190 and includes an orifice 198. A fastening pin or screw 199 is adapted to extend through the orifice 198 of the protrusion 197 and, in use, apply pressure to the protrusion to reduce the width of the slot 190 and force the blade 180 to apply appropriate pressure to the tube being cut, as explained in detail below.

[0107] Now for reference Figure 3A , 3B 3C, 3D, 3E, and 3F are the methods used to form... Figures 1A to 1E A perspective view of the steps involved in cutting a tube, which is part of the device's tube cutting subassembly.

[0108] like Figure 3A As seen, the hollow elongated tube 300 is disposed outside the device 100 and aligned with the recess 192 of the slot 190 of the cutting sub-assembly 170.

[0109] The slender tube 300 can be formed from any suitable material, and is typically formed from metals (such as aluminum) or flexible plastics.

[0110] In some embodiments, the outer diameter of the slender tube is in the range of 3 mm to 5 mm.

[0111] In some embodiments, the diameter of the hollow portion of the slender tube is in the range of 2 mm to 4 mm.

[0112] In some embodiments, the wall thickness of the elongated tube is in the range of 0.25 mm to 1 mm.

[0113] In some embodiments, in step 3A, substantially as described above, before inserting the tube into the device 100, the user may use the anchoring element 112 to anchor the device to a work surface, such as a table.

[0114] As can be seen, the tip of the anchor screw 160 rises above the protrusion 122 and the slot 124, and the cutting sub-assembly is oriented such that the head of the fastening screw 199 points downwards, away from the top surface 103.

[0115] exist Figure 3B In this configuration, the elongated tube 300 has been inserted into the slot 124 between the protrusion 122 to the desired extent via the recess 192 of the slot 190 and the hollow portion of the shroud of the cutter assembly 170. In some embodiments, the user can use the markings on the protrusion 122 to know the length of the tube 300 disposed within the slot 124 between the position of the blade 180 and the end of the tube. As can be seen, the orientation of the anchor screw 160, the cutter assembly 170, and the fastening screw 199 is relative to... Figure 3A It remains unchanged.

[0116] exist Figure 3C In this arrangement, the user has rotated the anchoring screw 160 to engage the section of the elongated tube 300 arranged within the slot 124, and has anchored the elongated tube 300 in place before cutting it. In this arrangement, the blade 180 engages the tube 300.

[0117] Once the elongated tube 300 is anchored, the user rotates the cutting sub-assembly 170 within the recess 150 and relative to the rest of the device 100 and relative to the tube 300, as follows: Figure 3D and 3E As shown. Figure 3D and 3EEach of the figures shows a 90-degree rotation of the cutting subassembly 170. The rotation of the cutting subassembly 170 causes a corresponding rotation of the blade 180 around the tube 300. Due to the engagement of the blade 180 with the tube 300, the rotation of the cutting subassembly 170 results in a partial cut of the tube.

[0118] As the user continues to rotate the cutting sub-assembly, the blade cuts deeper and deeper into the tube until the tube is completely cut into a first portion 300a anchored within the device 100 and a second portion 300b outside the device, as shown. Figure 3F As shown.

[0119] In some embodiments, after the cutting assembly 170 has rotated one or more times, the user can twist and tighten the screw 199 to bring the protrusions 197 closer together, thereby increasing the pressure applied by the blade to the tube to facilitate cutting more of the inner portion of the tube. This is particularly useful when the tube is formed of a relatively thick material.

[0120] After the tube is cut, the user can remove the cut tube portion from the slot 124 by releasing the anchor screw 160 and sliding the cut tube portion out of the slot 124 away from the cutting sub-assembly 170 or through the cutting sub-assembly 170.

[0121] In some embodiments, the pressure applied by the blade 180 to the tube 300 causes the tube to deform at the cutting point. In some such embodiments, the device 100 may also include a reshaping protrusion on which the cut tube 300a can be placed to restore its end to a rounded shape.

[0122] Now for reference Figure 3G , 3H And 3I, these are perspective views of the steps of bending tube 310 using a portion of the tube bending sub-assembly 130 of the forming device 100, the tube 310 being as shown about Figures 3A to 3F The previously cut tube as described, or a complete tube as provided by the manufacturer or retailer.

[0123] like Figure 3G As seen, by rotating the handle 136 from parallel to the protrusion 122 to perpendicular to it, the device 100 is prepared for bending the tube 310. The tube 310 is not yet placed in the device 100.

[0124] In the next step, such as Figure 3H As shown, tube 310 is inserted into bending assembly 130, located between disc base 132 and second pin 148, such that tube 310 engages groove 134 and is disposed between arms of receiving portion 140.

[0125] Figure 3IThe next step of the bending process is shown, in which the handle 136 rotates relative to the body 102 and relative to the disc-shaped base 132. The pin 148 rotates together with the handle 136 and pushes the tube 310 to bend around the base 132. The degree of bending of the tube 310 can be controlled by the angle at which the user rotates the handle 136. Rotating the handle 45 degrees will cause the tube 310 to bend 45 degrees from its initial state (straight or 180 degrees), resulting in an angle of 135 degrees. Rotating the handle 120 degrees will cause the tube 310 to bend 120 degrees from its initial straight state, resulting in an angle of 60 degrees. As shown, rotating the handle 90 degrees results in a 90-degree bend in the tube 310.

[0126] When using the tubes and connectors described herein, users typically prepare multiple hollow elongated tubes by cutting and / or bending the tubes to form the desired configuration for constructing structural components using the building toys of the present invention. In the building toys according to the present invention, the hollow elongated tubes are connected to each other using connectors according to embodiments of the present invention.

[0127] Some connectors, such as those mentioned here. Figures 4A to 17C The described connectors are designed for connection to at least one tube. Such connectors include a base defining at least one base surface and at least one pin extending outward from said at least one base surface.

[0128] In some embodiments, the at least one pin has: a first longitudinal segment and a second longitudinal segment, both having a first circumference; and a recessed longitudinal segment between the first longitudinal segment and the second longitudinal segment, the recessed longitudinal segment having a second circumference, wherein the second circumference is smaller than the first circumference.

[0129] In some such embodiments, at least one or each of the first and second longitudinal segments is significantly longer than the third longitudinal segment. In some embodiments, the ratio between the length of the first longitudinal segment and the length of the third longitudinal segment is at least 2:1. In some embodiments, the ratio between the length of the second longitudinal segment and the length of the third longitudinal segment is at least 2:1.

[0130] In other embodiments, the at least one pin is a cylindrical pin defining a tubular hollow portion adapted to receive a tube therein. The at least one tube can be held within the tubular hollow portion by friction.

[0131] As shown below, many different types of connectors meet these requirements. Some connectors include multiple pins and can be connected to multiple different tubes. In some cases, multiple pins extend from a single base surface, while in others, the pins extend from a base having multiple base surfaces.

[0132] Some connectors can be interconnected to form pivotable connectors, rotatable connectors, or other movable connectors. Some connectors include a hollow aperture through which an elongated foil tube can extend, allowing the connector to slide along the elongated tube. The aperture can also be adapted for snap-fit ​​connection with another connector using a suitable snap-fit ​​connection mechanism as described below.

[0133] Some connectors, such as those mentioned below Figures 18A to 27D The types described are interim connectors or support connectors, which are suitable for connecting two other connectors. These support connectors allow for the creation of more complex and intricate structures, and allow for additional degrees of freedom between the connector and / or the tube.

[0134] Some connectors may include electronic components, such as LEDs, attached to or disposed within the base of the connector. In some such embodiments, power for operating the electronic components may be supplied via at least one conductive tube connected to the connector.

[0135] Some connectors can be fixedly or rotatably attached to motors, such as servo motors or rotary motors, and facilitate the construction of structural components that can move dynamically and autonomously without requiring the user to provide force to move the constructed components. In some embodiments, such motors can be coded by the user to perform specific sequences of motions or actions, for example, by communicating with a suitable application installed on a mobile computing device.

[0136] Some examples of connectors suitable for use as parts of the toy construction of this invention are described in detail below. For all the connectors described, some structural elements are similar. For the sake of brevity, these structural elements are described once in the first figure in which they appear, and when these structural elements appear again, the description is referred to by explicitly stating that the structure of an element is equivalent to the structure of the previously described structural element.

[0137] Now for reference Figure 4A and 4B These are, respectively, perspective and side plan views of an end connector 400 according to an embodiment of the disclosed technology.

[0138] As can be seen, the terminal connector 400 includes a base 402 having a flat surface 404 and a curved surface 406. Extending outward from the flat surface 404 are pins 407. Pins 404 include a first longitudinal segment 408a and a second longitudinal segment 408b, which are separated by a recessed longitudinal segment 410. The second segment 408b terminates at a partially tapered end 412.

[0139] In some embodiments, the first longitudinal segment 408a and the second longitudinal segment 408b have a first circumference, and the recessed longitudinal segment 410 has a second circumference, wherein the second circumference is smaller than the first circumference.

[0140] In some embodiments, at least one or each of the first longitudinal segment 408a and the second longitudinal segment 408b is significantly longer than the recessed longitudinal segment 410. In some embodiments, the ratio between the length of the first longitudinal segment 408a and the length of the recessed longitudinal segment 410 is at least 2:1. In some embodiments, the ratio between the length of the second longitudinal segment 408b and the length of the recessed longitudinal segment 410 is at least 2:1.

[0141] In use, a tube, such as the cut tube 300 and / or bent tube 310 described above, can be placed on the pin 407 to connect the tube to the connector 400. In such an embodiment, the pin 407 can be inserted into the hollow portion of the tube 300 or 310. In some embodiments, the tube 300 or 310 can be crimped onto the pin 407, as described below regarding Figures 30A to 30C As stated above.

[0142] For further reference Figure 4C , 4D 4E and 4E are perspective, side plan and front plan views of end connector 400' according to another embodiment of the disclosed technology, respectively.

[0143] The connector 400' includes a base 402' defining a base surface. Extending outward from the base surface is a tubular pin 417, which includes a tubular body 418 defining an internal hollow portion 419. In use, a tube, such as the cut tube 300 and / or bent tube 310 described above, can be placed into the internal hollow portion 419 of the pin 417 to connect the tube to the connector 400. In such an embodiment, the outer surface of the tube can frictionally engage the inner surface of the tubular body 418 without crimping the tube.

[0146] Now for reference Figure 6A , 6B Views 6C and 6C are, respectively, a perspective view, a side plan view, and a front plan view of a male pivot connector 440 according to an embodiment of the disclosed technology. As can be seen, the male pivot connector 440 includes a base 442 having a surface 444, similar to... Figure 4A and 4B Pin 447 of pin 407 extends from this surface. A longitudinally flat protrusion 448 forming the male pivot portion of the connector extends away from pin 447 from the opposing surface of the base 442. The longitudinally flat protrusion includes two flat surfaces 450a and 450b, each flat surface including a recess 452. The recess 452 is adapted to receive a corresponding protrusion of the female pivot connector, as described herein, for example, regarding... Figures 7A to 7C As mentioned above.

[0147] For further reference Figure 6D , 6E 6F and 6F are perspective views, side plan views, and front plan views, respectively, of a male pivot connector 440' according to another embodiment of the disclosed technology. The male pivot connector 440' is substantially similar to the male pivot connector 440, wherein pins 447 are replaced by tubular pins 457, substantially similar to... Figures 5C to 5E The tubular pin 437, or essentially similar to Figures 4C to 4E 417 tubular pins.

[0148] Figure 7A , 7B 7C and 7C are perspective, side plan, and front plan views, respectively, of a female pivot connector 460 according to an embodiment of the disclosed technology, which is adapted to connect to Figures 6A to 6C Connector 440 or Figures 6D to 6FThe connector 440'. As can be seen, the female pivot connector 460 includes a base 462 having a surface 464, and... Figure 4A and 4B Pin 407, similar to pin 467, extends from this surface. A pair of longitudinal protrusions 468 forming the female pivot portion of the connector extend away from pin 467 from the opposing surface of the base 462. The protrusions 468 have a gap 470 between them. A substantially hemispherical protrusion 472 extends from each longitudinal protrusion 460 into the gap 470.

[0149] For further reference Figure 7D , 7E 7F and 7F are perspective, side, and front views, respectively, of a female pivot connector 460' according to another embodiment of the disclosed technology. The female pivot connector 460' is substantially similar to the female pivot connector 460, except that pins 467 are replaced by tubular pins 477, and is substantially similar to... Figures 5C to 5E The tubular pin 437, or essentially similar to Figures 4C to 4E 417 tubular pins.

[0150] In use, the protrusion 472 of connector 460 or 460' is adapted to be fitted to Figures 6A to 6C Connector 440 or Figures 6D to 6F In the recess 452 of connector 440', the longitudinal protrusion 448 is located within the gap 470. In this arrangement, connectors 440 / 440' and 460 / 460' can pivot relative to each other about an axis formed by the protrusion 472 seated in the recess 452.

[0151] Figure 8A , 8B 8C and 8C are perspective views, side plan views, and front plan views of a sliding end connector 480 according to an embodiment of the disclosed technology, respectively. As can be seen, the sliding end connector 480 includes a base 482 having a surface 484, similar to... Figure 4A and 4B The pin 487 of the plug 407 extends from this surface. A cylindrical portion 488 having a hollow portion 490 is connected via a neck portion 492 to the opposite surface of the base 482, away from the pin 487. The cylindrical portion is arranged such that its longitudinal axis 494 is perpendicular to the longitudinal axis 496 of the pin. The diameter of the hollow portion 490 is slightly larger than the diameter of the tube, for example... Figures 1A to 1E The tube 200 allows the tube to be arranged within the hollow portion 490 and to slide relative to the pin 487 within the hollow portion 490.

[0152] In some embodiments not explicitly shown, pin 487 may be composed of... Figures 5C to 5E tubular pin 437 or Figures 4C to 4EThe tubular pin 417 is replaced by a similar or identical tubular pin.

[0153] Figure 9A , 9B 9C and 9C are perspective views, side plan views, and front plan views of a snap-fit ​​connector 500 according to an embodiment of the disclosed technology. As can be seen, the snap-fit ​​connector 500 includes a base 502 having a surface 504, and... Figure 4A and 4B Pin 407, similar to pin 507, extends from this surface. A pair of longitudinal protrusions 508 forming a snap-fit ​​portion of the connector extend from the opposite surface of the base 502 away from pin 507. The protrusions 508 have a gap 510 between them. Each protrusion 508 terminates at one end distal to pin 507 in a radially outward protrusion 512, which has a locking surface 514.

[0154] In some embodiments not explicitly shown, pin 507 may be composed of... Figures 5C to 5E tubular pin 437 or Figures 4C to 4E The tubular pin 417 is a similar or identical tubular pin replacement.

[0155] In use, the protrusion 508 of connector 500 is adapted to be assembled to Figures 8A to 8C The connector 480 is housed in the hollow portion 490, and a snap-fit ​​mechanism engages therein, such that the locking surface 514 engages with the longitudinal periphery of the cylindrical portion 488, thereby substantially locking the connectors 500 and 480. In this arrangement, pins 487 and 507 form a 90-degree angle.

[0156] Figure 10A and 10B Each is an embodiment of the disclosed technology. Figure 9A and 9B A perspective view of a first exemplary use of the snap-fit ​​connector 500. (See attached image.) Figure 10A What I saw was similar to Figures 1A to 1E The tube 520 of tube 200 is aligned with the pin 507 of the snap-fit ​​connector 500. Tube 520 can be a cut tube, for example... Figure 3F The pipe is 300a, and / or it can be a bent pipe, for example... Figure 3I Pipe 310. In Figure 10B In this process, the tube 520 is connected to the connector 500 by inserting the pin 507 into the hollow portion 522 of the tube 520 until the end 524 of the tube 520 engages with the surface 504 of the connector. In some embodiments, as described below... Figures 30A to 30C In more detail, the tube can be further secured to the connector by pressing it into the recess in pin 500.

[0157] The pins are tubular pins (e.g.) Figures 4C to 4E In an embodiment of the tubular pin 317, the tube 520 is inserted into the hollow portion of the tubular pin and held therein by friction.

[0158] It should be understood that, although Figure 10A and 10B The connection between tube 520 and a specific type of connector (i.e., snap-fit ​​end connector 500) is shown, but connecting the tube to... Figures 10A to 10B The connector process shown applies equally to any tube and any connector with pins similar to pin 507. Similarly, the process of connecting a tube to a connector with tubular pins is equivalent, regardless of the type of connector in which the tubular pins form part.

[0159] Figure 11A and 11B Each is an embodiment of the disclosed technology. Figures 9A to 9C A perspective view illustrating a second exemplary use of the snap-fit ​​connector 500. (See diagram below.) Figure 11A As seen, the snap-fit ​​connector 500 and the support connector 530 are arranged adjacent to and aligned, with the support connector 530 including a base 532. The male pivot portion 534 is similar to the one described above. Figures 6A to 6C The described male pivot portion extends from one surface of the base 532. The sliding connection portion 536 is similar to the one described above. Figures 8A to 8C The described sliding connection portion extends from the opposite surface of the base 532.

[0160] like Figure 11B As seen, connectors 500 and 530 are connected to each other, such that the longitudinal protrusion 508 of the snap-fit ​​connector 500 extends through the hollow portion 538, similar to... Figures 8A to 8C The hollow portion 490. In this arrangement, the cylindrical portion 539 of the connector 520 is arranged and locked between the base surface 506 and the locking surface 514 of the connector 500, and the protrusion 512 extends from the cylindrical portion 539.

[0161] It should be understood that, although Figure 11A and 11B The connection between the snap-fit ​​connector and a specific support connector is shown, but the process of connecting the snap-fit ​​connection portion to the sliding connection portion is relevant to any pair of connectors that include these connection components, regardless of the number or type of pins included in such connectors.

[0162] Figure 12A and 12B Each is an embodiment of the disclosed technology. Figures 7A to 7C A second exemplary perspective view of the female pivot connector 460. (See diagram below.) Figure 12A As seen, the female pivot connector 460 and the male pivot portion 534 of the support connector 530 are arranged adjacent to and aligned (see also...). Figure 11A and 11B ).

[0163] like Figure 12B As seen, connectors 460 and 530 are connected to each other, such that the longitudinal protrusion 540 of the male pivot portion 534 (similar to...) Figures 6A to 6C The longitudinal protrusion 448 is disposed within the gap 470 of the female pivot connector 460. The protrusion 472 is rotatably disposed within the corresponding recess 542 of the male pivot protrusion 534 (similar to...). Figures 6A to 6C Within the recess 452. In this arrangement, connectors 460 and 530 can pivot relative to each other about an axis extending through the protrusion 472 and the recess 542 in order to change the angular orientation between the pin 467 and the sliding connector portion 536.

[0164] Understandable, although Figure 12A and 12B The example illustrates the connection between a female pivot connector and a specific support connector, but the process of connecting male and female pivot connection portions to each other applies to any pair of connectors that include these connection components, regardless of the number or type of pins included in such connectors.

[0165] Now for reference Figure 13A and 13B These are, respectively, a perspective view and a front plan view of an extension connector 550 according to an embodiment of the disclosed technology. As can be seen, the extension connector 550 includes a base 552 having a first surface 554 and a second surface 556. Figure 4A and 4B Pin 407, similar to pins 557 and 558, extends longitudinally outward from the first surface 554 and the second surface 556, respectively. The extension connector 550 is adapted to extend the length of the tube by connecting the first tube to pin 557 and the second tube to pin 558, such that the resulting tube has the cumulative length of the first tube and the second tube.

[0166] In some embodiments not explicitly shown, one or both of pins 557 and 558 may be coupled with... Figures 5C to 5E tubular pin 437 or Figures 4C to 4E The tubular pin 417 is a similar or identical tubular pin replacement.

[0167] Figure 14A , 14B14C and 14C are perspective, side plan, and front plan views, respectively, of a three-way sliding connector 560 according to an embodiment of the disclosed technology. As can be seen, the three-way sliding connector 560 includes a triangular base 562, shown here as an equilateral triangle, extending along a longitudinal axis 563, and has three side surfaces 564 as well as a front surface and a rear surface 566. Pins 567 extend from each of the side surfaces 564, and are similar to... Figure 4A and 4B Pin 407.

[0168] Connector 560 also includes a longitudinal aperture 568 extending longitudinally through base 562, which is similar to Figures 8A to 8C The orifice 490. The orifice 568 is adapted to allow a tube to be slidably arranged through the orifice, and / or adapted to be engaged with a snap-fit ​​connection of a suitable connector, for example... Figures 9A to 9C The connector 500, basically as about Figure 11A and 11B As mentioned above.

[0169] Now refer to another source Figure 14D , 14E 14F and 14F are perspective, side, and front views, respectively, of a three-way sliding connector 560' according to another embodiment of the disclosed technology. The three-way sliding connector 560' is substantially similar to the three-dimensional sliding connector 560, wherein each pin 567 is replaced by a tubular pin 567', substantially similar to... Figures 5C to 5E tubular pin 437, or similar Figures 4C to 4E The tubular pin 417. In some embodiments (not explicitly shown), only some pins 567 may be replaced by tubular pins 567', such that the resulting three-dimensional sliding connector may have a combination of pins and tubular pins extending therefrom.

[0170] When the tubes are connected to each pin 567 or 567' in the orientation of connector 560, a 120-degree angle is formed between every two adjacent tubes, and all tube connections lie in a single plane. If a fourth tube is slidably arranged in orifice 568, it forms a 90-degree angle with each tube on pin 567 or in tubular pin 567' and is perpendicular to the plane of pins 567 / 567'. However, it should be understood that base 562 may be arranged differently, such that it is not an equilateral triangle, or that the pins are not arranged in a single plane, in which case the angular arrangement of pins 567 / 567' will be different. Furthermore, in some embodiments, orifice 568 may be omitted, allowing the connector to be used only to connect three tubes in a single plane.

[0171] Figure 15A , 15B15C and 15C are perspective, side plan, and front plan views, respectively, of a four-way sliding connector 570 according to an embodiment of the disclosed technology. As can be seen, the four-way sliding connector 570 includes a quadrilateral base 572, shown here as a square, extending along a longitudinal axis 573, and has four side surfaces 574 as well as a front surface and a rear surface 576. Pins 577 extend from each of the side surfaces 574, and are similar to... Figure 4A and 4B Pin 407. In some embodiments, some or all of pins 577 may be replaced by tubular pins, each with Figures 5C to 5E tubular pin 437 or Figures 4C to 4E The tubular pins are the same as or similar to those of 417.

[0172] Connector 570 also includes a longitudinal aperture 578 extending longitudinally through base 572, similar to Figures 8A to 8C The orifice 490. The orifice 578 is adapted to allow a tube to be slidably arranged through the orifice, and / or adapted to be engaged with a snap-fit ​​connection of a suitable connector, for example... Figures 9A to 9C The connector 500, basically as about Figure 11A and 11B As mentioned above.

[0173] When the tubes are connected to each pin 577 in the orientation of connector 570, a 90-degree angle is formed between every two adjacent tubes, and all tube connections lie in a single plane. If a fifth tube is slidably arranged in orifice 578, it forms a 90-degree angle with each tube on pin 577 and is perpendicular to the plane of pin 577. However, it is understood that base 572 may be arranged differently, such that it is not an equilateral square, or that the pins are not arranged in a single plane, in which case the angular arrangement of pins 577 will be different. Furthermore, in some embodiments, orifice 578 may be omitted, allowing the connector to be used only to connect four tubes in a single plane.

In some embodiments, the base 582 may also include a pair of slots 589 disposed on either side of the additional surfaces 586 along the longitudinal axis of the pin 587.

[0175] In some embodiments, pin 587 may be connected to... Figures 5C to 5E tubular pin 437 or Figures 4C to 4E The tubular pin 417 is replaced by a similar or identical tubular pin.

[0176] Figure 17A , 17B Figures 17 and 17C are perspective, front plan, and side plan views, respectively, of an extended snap-fit ​​connector 590 according to an embodiment of the disclosed technology. As can be seen, the extended snap-fit ​​connector 590 includes a base portion 592 having a first surface 594 and a second surface 596. Extending longitudinally from the second surface 596 is a cylindrical snap-fit ​​portion 598, which terminates at an end face 600. The cylindrical snap-fit ​​portion 598 has a smaller circumference than the base portion 592. Adjacent to the end face 600, the radially outwardly extending cylindrical snap-fit ​​portion 598 consists of a pair of protrusions 602, each protrusion 602 having a locking surface 604 facing the second surface 596. The first pin 607a and the second pin 607b are both similar to Figure 4A and 4B Pins 407 extend longitudinally outward from surfaces 594 and 600, respectively. A through slot 608 extends through a portion of the snap-fit ​​portion 598 and a portion of the pin 607b, the slot 608 facilitating slight clamping of the snap-fit ​​portion 598 during their snap-fit ​​engagement. In some embodiments, one or both of pins 607a and 607b may be provided with… Figures 5C to 5E tubular pin 437 or Figures 4C to 4E The tubular pin 417 is a similar or identical tubular pin replacement.

[0177] In use, connector 590 can be arranged longitudinally through the sliding connector portion, for example, regarding Figures 8A to 8C As described. In this arrangement, the cylindrical portion of the sliding connector will be locked between surfaces 596 and 604.
