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

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

Reference is now made to <FIG>, <FIG>, <FIG>, <FIG>, <FIG>, and <FIG>, which are perspective view illustrations of steps of cutting a tube using the tube cutting subassembly forming part of the device of <FIG>.

As seen in <FIG>, a hollow elongate tube <NUM> is disposed outside of device <NUM>, and is aligned with recess <NUM> of slot <NUM> of the cutting subassembly <NUM>.

The elongate tube <NUM> may be formed of any suitable material, and is typically formed of metal, such as aluminum, or of a pliable plastic.

In some embodiments, the exterior diameter of the elongate tube is in the range of <NUM> to <NUM>.

In some embodiments, the diameter of the hollow of the elongate tube is in the range of <NUM> to <NUM>.

In some embodiments, the thickness of the wall of the elongate tube is in the range of <NUM> to <NUM>.

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

As seen, the tip of anchoring screw <NUM> is raised above protrusions <NUM> and slot <NUM>, and the cutting subassembly is oriented such that the head of tightening screw <NUM> is directed downward, away from top surface <NUM>.

In <FIG>, the elongate tube <NUM> has been inserted, via recess <NUM> of slot <NUM> and the hollow of the cowl of cutting subassembly <NUM> into slot <NUM> between protrusions <NUM>, to a desired degree. In some embodiments, the user may use the indications, marked on protrusions <NUM>, to know the length of the tube <NUM> disposed within slot <NUM>, between the location of blade <NUM> and the end of the tube. As seen, the orientation of anchoring screw <NUM>, of cutting subassembly <NUM>, and of tightening screw <NUM>, remains unchanged relative to <FIG>.

In <FIG>, the user has rotated anchoring screw <NUM> to engage the section of elongate tube <NUM> disposed within slot <NUM>, and to anchor the elongate tube <NUM> in position prior to cutting thereof. In this arrangement, blade <NUM> engages tube <NUM>.

Once the elongate tube <NUM> is anchored, the user rotates cutting subassembly <NUM>, within indentation <NUM> and relative to the remainder of device <NUM> and to tube <NUM>, as illustrated in <FIG> and <FIG>. Each of <FIG> and <FIG> which shows a <NUM>-degree rotation of cutting subassembly <NUM>. Rotation of cutting subassembly <NUM> causes corresponding rotation of blade <NUM> about tube <NUM>. Due to the engagement of blade <NUM> with tube <NUM>, rotation of cutting subassembly <NUM> results in partial cutting of the tube.

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 <NUM>, and a second portion 300b outside of the device, as illustrated in <FIG>.

In some embodiments, following one or more full rotations of cutting assembly <NUM>, the user may twist and tighten screw <NUM>, causing protrusions <NUM> 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.

Following cutting of the tube, the user may remove the cut tube portion from slot <NUM> by releasing anchoring screw <NUM> and sliding the cut tube portion out of slot <NUM> away from cutting subassembly <NUM>, or through cutting subassembly <NUM>.

In some embodiments, the pressure applied by blade <NUM> to tube <NUM> causes deformation of the shape of the tube at the cutting point. In some such embodiments, device <NUM> 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.

Reference is now made to <FIG>, <FIG>, and <FIG>, which are perspective view illustrations of steps of bending a tube <NUM>, which may be a tube previously cut as described with respect to <FIG>, or a complete tube as provided by a manufacturer or retailer, using a tube bending subassembly <NUM> forming part of the device <NUM>.

As seen in <FIG>, the device <NUM> is prepared for bending of tube <NUM>, by rotating handle <NUM> from being parallel to the protrusions <NUM>, to being perpendicular thereto. The tube <NUM> is not yet placed in the device <NUM>.

At a next step, shown in <FIG>, tube <NUM> is inserted into the bending assembly <NUM>, between disc shaped base <NUM> and second pin <NUM>, such that the tube <NUM> engages groove <NUM> and is disposed between the arms of receiving portion <NUM>.

<FIG> shows the next step of the bending process, in which handle <NUM> is rotated relative to main body <NUM> and relative to disc shaped base <NUM>. The pin <NUM> rotates together with handle <NUM>, and pushes the tube <NUM> to bend about base <NUM>. The degree of bending of the tube <NUM> may be controlled by the angle to which the user rotates the handle <NUM>. Rotating the handle <NUM> degrees, will result in the tube <NUM> being bent <NUM> degrees from the initial state (straight line or <NUM>-degree angle), and thus the tube will have an angle of <NUM> degrees. Rotating the handle <NUM> degrees, will result in the tube <NUM> being bent <NUM> degrees from its initial, straight line, state, and in the tube having an angle of <NUM> degrees. Rotating the handle <NUM> degrees, as illustrated, results in the tube <NUM> having a bend of <NUM> degrees.

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. In the construction toy according to the present invention, hollow elongate tubes are connected to one another using connectors according to embodiments of the present invention.

Some connectors, such as those described herein with respect to <FIG>, are designed for connection to at least one tube. Such connectors include a base defining at least one base surface, at least one prong extending outwardly from the at least one base surface.

As seen hereinbelow, many different types of connectors meet these requirements. Some connectors include multiple prongs and are connectable to multiple different tubes. In some cases, multiple prongs extend from a single base surface, whereas in other cases the prongs extend from a base having multiple base surfaces.

Some connectors are connectable to one another, so as to form pivotable connectors, rotatable connectors, or otherwise movable connectors. Some connectors include a hollow bore through which an elongate foil tube may extend, such that the connector may slide along the elongate tube. The bore may further be suitable for snap fit connection of another connector thereto, using a suitable snap fit connection mechanism as described hereinbelow.

Some connectors, such as those described hereinbelow with respect to <FIG>, are interim connectors, or supporting connectors, adapted for connection thereto of two other connectors. Such supporting connectors allow for creation of more complex and intricate structures, and enable additional degrees of freedom between connectors and/or tubes.

Some connectors may include electronic components, such as LED lights for example attached to or disposed within the base of the connector. In some such embodiments, power for operating the electronic components may be provided via at least one electrically conductive tube connected to the connector.

Some connectors may be fixedly or rotatably attached to a motor, such as a servo motor or a rotating motor, and facilitate construction of structures which can move dynamically and autonomously, without the user providing force for moving components of the constructed structure. In some embodiments, such motors may be coded by the user to carry out a specific sequence of movements or actions, for example by communication with a suitable app installed on a mobile computing device.

Some examples of connectors suitable for use as part of the construction toy of the present invention are described specifically hereinbelow. Some structural elements are similar for all the connectors described. For brevity, these structural elements are described once with respect to the first drawing in which they appear, and the description is referenced when these structural elements appear again, by explicitly stating that the structure of one element is equivalent to the structure of a previously described element.
