     TECHNICAL FIELD 
     This invention relates to construction components, and particularly to construction components that can be used both in toy construction sets and puzzles. 
     BACKGROUND 
     One known analog from prior art is the construction component from the company “LEGO”, containing a base, which is created, as a rule, in the form of a parallelepiped with one or more interlocking joints (patent RU 2150985 of 20 Jun. 2000). 
     A disadvantage of the known construction component is poor functionality because its design permits only one possible type of connection between identical construction components. 
     SUMMARY OF THE INVENTION 
     The object of the claimed invention is to create a construction component which provides many options for interlocking similar components. 
     The technical result comprises increasing the functional possibilities of the construction component by increasing the connection options of the proposed construction component with other components of the same type and introducing additional elements to provide a movable connection. 
     The technical result of the first construction component embodiment is achieved due to the construction component containing a base and interlocking joint. The base is made flat and has a rectangular form, with sides made in multiples of &lt;&lt;a&gt;&gt;. The interlocking joint is created by positioning protrusions on the base, which form four groups of protrusions. The first group of protrusions is positioned at least on one side of the base in tubular form, having ring-shaped cross-sections with an outer diameter equal to &lt;&lt;a&gt;&gt;. The height of the protrusions in the first group is greater than &lt;&lt;0.5a&gt;&gt; but no greater than &lt;&lt;a&gt;&gt;. The second group has protrusions positioned on at least one side of the base that are tubular, with cross-sections in the form of a square having side length in the tubular protrusion equal to &lt;&lt;a&gt;&gt;. The height of the protrusions in the second group is equal to &lt;&lt;0.5a&gt;&gt;. In the third group, protrusions are made in the form of rectangular plates, positioned with its midline on the ends of the base, flush with these ends, and having ledges with width equal to &lt;&lt;a&gt;&gt; along the short sides protruding not more than &lt;&lt;0.5a&gt;&gt; from the base ends. The ledges are angled towards each other with the gap formed between their end parts no greater than &lt;&lt;a&gt;&gt;. Protrusions in the fourth group are made in the form of corners, having shelves positioned perpendicular to the base planes on its adjacent ends and flush with these ends. Shelves have a length equal to &lt;&lt;a&gt;&gt; and width no greater than &lt;&lt;0.5a&gt;&gt;. All protrusions are positioned on the base in accordance with the coordinate grid of mutually perpendicular lines parallel to base edges. The distance between neighboring lines of the coordinate grid is equal to &lt;&lt;2a&gt;&gt;. The distance between the base edges and neighboring lines on the coordinate grid −&lt;&lt;0.5a&gt;&gt;. Protrusions from the first group are positioned at points where the grid lines intersect. Protrusions from the second group are positioned at points where the diagonals of the cells of the coordinate grid intersect. Protrusions from the third group are positioned in the middle between the neighboring protrusions from the first group that are positioned flush with the ends of the base. Protrusions from the fourth group are positioned in the corners of the base.

The height of protrusions  2  and  7  (see  FIG. 6 ) &lt;&lt;H&gt;&gt; is greater than &lt;&lt;0.5a&gt;&gt; but no greater than &lt;&lt;a&gt;&gt;. Protrusions from the first group are made in the form of protrusions  7  with cross-shaped cross-section form, where the distance between the opposing ends of the cross is equal to &lt;&lt;a&gt;&gt;, and/or protrusions  2  with tubular form having ring-shaped cross-sections with an outer diameter equal to &lt;&lt;a&gt;&gt;. The inner side of the ring can be made ported and/or with grooves closed on both ends. In the second group, protrusions  4  are made in the form of rectangular plates, positioned with its midline on the ends of the base  1 , and having ledges, flush with these ends, with width equal to &lt;&lt;a&gt;&gt; (see  FIG. 8 ) along the short sides protruding from the base ends by a length “B” (see  FIG. 7 ), which is not more than &lt;&lt;0.5a&gt;&gt;, angled towards each other with the gap formed between their end parts no greater than &lt;&lt;a&gt;&gt; (see  FIG. 5 ). Protrusions  6  in the third group are made in the form of corners, having shelves positioned perpendicular to the base  1  planes on its adjacent ends and flush with these ends, with a length equal to &lt;&lt;a&gt;&gt; (see  FIG. 8 ) and width &lt;&lt;d&gt;&gt; (see  FIG. 5 ) no greater than &lt;&lt;0.5a&gt;&gt;. Protrusions are positioned on the base  1  in accordance with the coordinate grid  8  (see  FIG. 10 ) of mutually perpendicular lines parallel to base  1  edges, wherein the distance between neighboring lines of the coordinate grid is equal to &lt;&lt;2a&gt;&gt;, wherein the distance between the base edges and neighboring lines on the coordinate grid −&lt;&lt;0.5a&gt;&gt;. Protrusions  2  from the first group are positioned at points where the coordinate grid  8  lines intersect. Protrusions  4  from the second group are positioned in the middle between the neighboring protrusions  2  from the first group that are positioned flush with the ends of the base  1 . Protrusions  6  from the third group are positioned in the corners of the base  1 . 
     When connecting constructor elements to one another, the protrusions of different elements interlock with each other. Interlocking is based on the force of friction, occurring between protrusions during close contact with each other. When connecting elements to one another, the protrusions of different groups simultaneously engage in interlocking, which provides improved connection strength. 
     Let&#39;s consider examples of such connections. 
       FIG. 11  shows two constructor elements prior to connecting, with protrusions entering into interlock with each other indicated. The top element  9  is implemented according to the fourth embodiment and the lower element  10  is implemented according to the third embodiment. A protrusion  11  from the first group of element  9  enters into interlock with protrusion  12  of the second group of element  10 . Protrusion  13  from the second group of element  9  enters into interlock with protrusion  14  from the first group of element  10 . Protrusion  15  from the second group of element  9  enters into interlock with protrusion  16  from the first group of element  10 . Protrusion  17  from the first group of element  9  enters into interlock with protrusion  18  from the third group of element  10 .  FIG. 12  shows these elements in an interlocked state. 
       FIG. 13  shows two constructor elements  19  and  20  prior to connecting, with indicated protrusions entering into interlock with each other upon connection. Both elements are implemented according to the third embodiment. Protrusion  21  from the third group of element  19  enters into interlock with four protrusions of element  20 : protrusion  22  from the third group, protrusion  23  from the second group, protrusion  24  from the first group, and protrusion  25  from the first group. Protrusion  23  from the second group of element  20  enters into interlock with protrusion  26  from the fourth group of element  19 .  FIG. 14  shows these elements in an interlocked state. 
       FIG. 15  shows two constructor elements prior to connecting with indicated protrusions entering into interlock with each other upon connection. Constructor element  27  is implemented according to the fourth embodiment, and element  28  is implemented according to the third embodiment. Protrusion  29  from the second group of element  27  enters into interlock with protrusion  30  from the third group of element  30 .  FIG. 16  shows these elements in an interlocked state. 
     The constructor is characterized by the set of three types of elements it comprises. The first type of constructor element is analogous to constructor elements, implemented according to the first or third embodiments (see position  31  on  FIG. 17 ). The second type of constructor element (see position  32  on  FIG. 18 ) is analogous to constructor elements, implemented according to the second and fourth embodiments (see  FIG. 18 ). The third type of constructor element  33  (see  FIGS. 17,19 ) is made tubular and/or rod-shaped and are equipped with, at least, one protrusion on a side surface with the ability to longitudinally move constructor elements of the third type into protrusions with ring-shaped cross-section when placing protrusions of constructor elements of the third type into protrusions with ring-shaped cross-sections from the first group of elements of the first  31  or second  32  type (see  FIGS. 17,19 ) when placing protrusions of constructor elements of the third type into grooves of protrusions with ring-shaped cross-section.  FIG. 19  shows the placement of element  33  of the third type into the closed grooves of the protrusion from the first group of element  32  of the second type. The protrusion is shown in cross-section, so the closed grooves can be seen. 
       FIG. 17  shows a set of constructor elements prior to being assembled into a construction, shown in  FIGS. 20 and 21 . 
     Protrusions of interlocking joints, for a more precise positioning of constructor elements during connection with each other, can be implemented with bevels, rounded off, sloped, and so forth. The base  1  can also be made with various openings to conserve materials.
