Referring to fig. 8, fig. 8 is a schematic view showing a structure in which two block elements 01 are vertically snap-fitted by a block connector 02, and includes two block elements 01 and one block connector 02, and the process of snap-fitting the two block elements 01 in different directions is achieved by the block connector 02 being snapped and rotated by a certain angle in the manner shown in fig. 8.
Referring to fig. 9 and 10, fig. 9 and 10 show a cross-sectional view of the detent arrangement of a building element 01 and a building element connector 02, the cross-sectional line being positioned as D-D in fig. 9, wherein 01B in fig. 10 is a groove in the building element 01 and 02C is a detent tab on the building element connector 02.
Referring to fig. 11, the structural illustration i of fig. 11 shows the fastening of an expansion element 03 to a building element 01, comprising a building element 01 and an expansion element 03. The expansion element 03 is snapped in the manner shown in the drawing and rotated by a certain angle, so that a snap-in fastening in the vertical direction on the building element 01 is achieved.
With reference to fig. 12, the structural illustration ii of fig. 12, in which the expansion element 03 is fastened to the building element 01, comprises a building element 01 and an expansion element 03. The expansion element 03 is snapped and rotated by a certain angle in the manner shown in the figure, so that the snap fastening in the horizontal direction on the building element 01 is achieved.
Referring to fig. 13, fig. 13 shows a sectional view of the structure of the expansion element 03 fastened to the toy building element 01. The position of the section lines is shown in fig. 13 as E-E, where 01B is a groove in the toy building element 01, 03B is the axis of rotation in the fixed coupling element, and 03C is a catch in the fixed coupling element.
Referring to fig. 1 to 4, and also to fig. 7 to 10, the toy building element 01 is a polyhedral toy building block with grooves 01B on each side, which is not limited in shape, and may be a tetrahedron, a hexahedron, an octahedron, etc., and the grooves are grooves in which the latch tabs 02C of the toy building connecting element 02 may rotate at a certain angle and have a certain elastic deformability, and are not limited in shape, and may be T-shaped, dovetail grooves, etc. The building block connector 02 is a building block with a snap piece and a certain elastic deformation capacity, which can rotate a certain angle in a groove on the building block element 01, and the shape is not limited, and can be T-shaped, triangular, square and the like. The shape of the engagement piece 02C on the building block connector 02 is not limited, and may be rectangular, triangular, trapezoidal, etc. When two building elements 01 need to be fixed, the clamping sheets of the building element connectors 02 are pressed into the grooves on any surface of one of the building elements 01, then the grooves on any surface of the other building element 01 are pressed into the other clamping sheet of the building element connectors 02, and the grooves on the two building elements 01 and the clamping sheets on the building element connectors 02 are pressed by rotating a certain angle, so that the two building elements 01 are fixed. During rotation, the catch tabs 02C on the building element connector 02 will rotate in the grooves 01B in the building element 01, and since there is a certain angle of inclination between the contact surfaces of the catch tabs 02C on the building element connector and the contact surfaces of the grooves of the building element, the contact surfaces on the grooves 01B will press the catch tabs of the building element connector 02 when the building element 01 rotates, causing the catch tabs of the building element connector 02 to elastically deform and generate a large pressing force. On one hand, after the building block connecting piece 02 is rotated by a certain angle, the clamping piece is rotated into the groove, so that the building block element cannot move in the vertical direction of the groove; on the other hand, the extrusion force generated when the clamping sheet is elastically deformed increases the extrusion force on the contact surface of the building element and the other building element, so that the building element needs very large friction force when moving in the horizontal direction of the groove, and the fixed clamping of different building elements on any groove position of any surface is realized. In this embodiment, as shown in fig. 7 to 10, since the contact surface of the latch piece on the block connector 02 and the contact surface of the groove on the block element have an inclination angle of 3 degrees, the latch piece on the block connector 02 generates a certain elastic deformation when rotated, thereby realizing the latch fixation between the block elements by rotating a certain angle on any groove position on any surface.
Referring to fig. 3 and 4, in order to facilitate the player to snap-fix the toy building element 01 by a fixed angle, i.e. by a fixed angle, the present application also designs a number of right angles to the part of the fixed axis 02B of the toy building connecting element 02, as shown in fig. 4. This feature allows the building element coupling member 02 to be rotatably fixed in the groove 01B of the building element 01 by a fixed angle, while the squaring process also allows the building element coupling member 02 to be rotatably fixed in the groove 01B of the building element 01 only in a fixed direction. This characteristic makes things convenient for the player to fix building blocks connecting piece 02 on building blocks element 01 fast, avoids the too big problem that leads to the rotation angle of needing readjustment again of rotation angle. In the characteristic, the shape of the rotary fixing shaft 02B on the building block connecting piece 02 is not limited, and the rotary fixing shaft can be square, hexagonal, semicircular and the like, the number and the positions of right angles are not limited, and the rotary fixing shaft can be two right angles with equal distance, four right angles with different distance and the like. In this example, the rotation fixing shaft 02B of the block coupling member 02 is a square rotation shaft, and two right-angle processes are performed on the rotation fixing shaft in this example so that the rotation fixing shaft 02B of the block coupling member 02 cannot rotate after rotating 90 ° in the groove 01B of the block 01, and at the same time, the right-angle processes as shown in fig. 4 also make the rotation fixing shaft 02B of the block coupling member 02 rotate only clockwise in the groove 01B of the block 01.
Referring to fig. 7, 1 to 4, and secondly, in order to meet the requirement of the toy building element 01 to be snapped in at a fixed position, the present embodiment also envisages a positioning hole 01A on the toy building element 01 and a positioning shaft 02A on the toy building element connector as in fig. 1 to 2. When the location axle 02A of building blocks connecting piece 02 aimed at the locating hole 01A of building blocks element 01 pressed in, when another building blocks element 01 rotated certain angle, the rotation axis of building blocks connecting piece 02 rotated in the locating hole of building blocks element 01 all the time to it is fixed to realize that building blocks element joint is fixed on appointed position. In this example, when the building element 01 shown in fig. 7 needs to be fixed in a fixed position on another building element 01 by means of snap-fitting, the relative position of the building element 01 is always kept unchanged when the building element 01 is rotated by means of the positioning hole and the positioning shaft, so as to meet the requirement that the building element 01 needs to be fixed in a fixed position by means of snap-fitting.
Referring to fig. 7, 1 to 4, in addition, in order to meet the need for feedback to the player of the spin-in-place when the building elements 01 are snap-fitted together, the present embodiment also envisages a projection 01C and a recess 01D on the building element 01 as shown in fig. 1 to 2. The convex platforms and the concave surfaces on the building block elements correspond to each other, and the number and the shape are not limited. When a toy building element is rotated to a given position, the projection on the toy building element will fall into the recess on the other toy building element, at which point the sound of the projection on the toy building element falling into the recess will give the player feedback of the rotation in place. In this example, the boss 01C of the 2 nd toy building element 01 will just sink into the recess 01D of the 1 st toy building element 01 after rotating into place, giving the player a good indication of the click-in-place.
Referring to fig. 1, 2, 5, 6, and 11 to 13, the building element 01 is a polyhedral building block having a groove 01B on each face, and the shape is not limited, and may be a tetrahedron, a hexahedron, an octahedron, or the like, and the groove is a groove in which the clip 03C of the expansion element 03 can rotate by a certain angle and has a certain elastic deformation capability, and the shape is not limited, and may be a T shape, a dovetail groove, or the like. The expansion element 03 is a building block with a clamping piece and a certain elastic deformation capacity and can rotate for a certain angle in a groove on the building block element 01, and the shape of the fixing connecting piece is not limited and can be T-shaped, triangular, square and the like. The shape of the engaging piece 03C on the expansion element 03 is not limited, and may be rectangular, triangular, trapezoidal, etc. The fixed connecting piece can be used independently, and also can be connected with an expansion component of the building block for use, and the expansion component of the building block is not limited in form and can be a gear, a windmill, a wheel, a battery pack and the like. When the extension element 03 is to be fixed to the building element 01, the engagement tabs 03C of the fastening connection are merely pressed into the grooves 01B in the building element 01, and the rotation through a certain angle causes the engagement tabs on the fastening connection to rotate into the grooves and to produce a certain compression, so that the fastening engagement of the extension element 03 on the building element 01 is achieved. During rotation, the clamping piece 03C of the expansion element 03 rotates in the groove 01B of the building element 01, and because the contact surface of the clamping piece 03C on the expansion element 03 and the contact surface of the groove 01B on the building element 01 have a certain inclination angle, when the expansion element 03 rotates, the contact surface of the groove on the building element 01 can extrude the clamping piece of the expansion element 03, so that the clamping piece on the expansion element 03 is elastically deformed and generates a larger extrusion force. On one hand, after the fixed connecting piece is rotated by a certain angle, the clamping sheet on the fixed connecting piece can rotate into the groove, so that the fixed connecting piece cannot move in the vertical direction of the groove; on the other hand, the pressing force generated when the clip elastically deforms increases the pressing force on the contact surface of the expansion element 03 and the building element 01, so that a very high friction force is required when the fastening connection moves in the horizontal direction of the groove of the building element. The expansion element 03 can thus be fixedly clamped in any groove position on any side of the building element 01. In this example, as shown in fig. 11 to 13, since the contact surface of the engaging piece on the extending element 03 and the contact surface of the groove on the building element 01 have an inclination angle of 3 degrees, when the extending element 03 rotates, the engaging piece on the fixing connector generates a certain elastic deformation, so that the extending element 03 can rotate at a certain angle in any groove position on any surface of the building element 01 to realize the engaging fixation.
See fig. 6 and 12. In order to facilitate the player to snap-fit the expansion element 03 to the building element 01 by rotating a fixed angle, the embodiment also designs a certain number of right angles (as shown in fig. 6) on the part of the rotating fixed shaft 03B of the expansion element 03. This feature allows the fixed axis of rotation 03B of the expansion element 03 to rotate only a fixed angle in the groove 01B of the block element 01, while the right angle treatment also allows the fixed axis of rotation 03B of the expansion element 03 to rotate only in a fixed direction in the groove 01B of the block element 01. This feature makes things convenient for the player to fix extension element 03 on building block element 01 fast, avoids the too big problem that leads to the rotation angle of needing readjustment again of rotation angle. In this feature, the shape of the rotating fixing shaft 03B on the expanding element 03 is not limited, and may be square, hexagonal, semicircular, etc., and the number and positions of the right angles are also not limited, and may be two right angles at equal intervals, four right angles at different intervals, etc. In this example, the axis of rotation of the expansion element 03 is a square axis of rotation, in this example (as shown in fig. 6) the axis of rotation is treated at two right angles so that the axis of rotation 03B of the expansion element 03 is not rotated any more after rotating 90 ° in the groove 01B of the building block 01, while the treatment at right angles as shown in fig. 6 also allows the axis of rotation 02B of the building block coupling 02 to rotate only clockwise in the groove 01B of the building block 01.
See fig. 1, 2, 5, 6, 12. Secondly, in order to meet the requirement for the engagement of the expansion element 03 in the retaining position of the toy building element 01, the embodiment also provides for the positioning holes 01A on the toy building element 01 and the positioning shafts 03A on the expansion element 03 as shown in fig. 1, 2, 5 and 6. When the positioning shaft 03A of the extension element is aligned with the positioning hole 01A of the building block element 01 and is pressed in and then rotates for a certain angle, the rotating fixing shaft on the extension element 03 always rotates in the positioning hole of the building block element 01, and therefore the extension element 03 is clamped and fixed at the appointed position on the building block element 01. In the present example (as shown in fig. 12), when the extending element 03 is fixed at a designated position on the building element 01 by means of snap-fit, the relative position between the extending element 03 and the building element 01 is always determined when the extending element 03 is rotated by means of the positioning hole and the positioning shaft, so that the extending element can be fixed at the designated position on the building element 01 by snap-fit quickly and stably.
See fig. 1, 2, 5, 6, 12. In addition, in order to satisfy the requirement of giving the player the feedback that the extension element 03 is rotated in place when the extension element 03 is snap-fitted to the building element 01, the present invention further designs a boss 03D on the extension element 03 as shown in fig. 5. The grooves 01B of the building element 01 correspond to the projections 03D of the expansion element 03, and the number and shape are not limited. When the expansion element 03 is rotated to a given position, the boss on the fixed connection will fall into the concave surface on the toy building element 01, at which point the sound of the boss on the expansion element 03 falling into the concave surface on the toy building element 01 will give feedback to the player that he is rotating in place (see fig. 12). Secondly, due to the projection 01C at the fixing position of the building element 01, when the extension element 03 is rotationally snapped at the fixing position of the building element 01 (as shown in fig. 12), the elastic deformation of the snap piece on the extension element 03 is increased, which easily causes the snap piece to be damaged. In the embodiment, a concave surface 01E (as shown in fig. 1) is formed at a fixed position of the building element 01, and when the expansion element 03 rotates, the boss 03D on the expansion element can rotate in the concave surface 01E on the building element 01, so that elastic deformation of the clamping piece of the expansion element 03 is reduced, and a player can conveniently and quickly clamp the expansion element 03 at a specified position of the building element 01. In this example (see fig. 13), when the expansion element 03 is snapped onto the toy building element 01, the projection on the expansion element 03 slides into the groove on the toy building element 01 after the expansion element 03 is rotated 90 degrees, and when the projection slides, a certain sound is given to the player to give feedback that the snap is in place. The player is prevented from rotating more than 90 degrees.
See fig. 5, 6 and 11. In order to solve the problem that the position of the expansion element 03 cannot be controlled when the expansion element 03 is fixed at any position of the toy building element 01 by rotation, the embodiment further designs a groove 03F on the expansion element 03 as shown in fig. 5 and 6, when the expansion element 03 fixed on the toy building element 01 needs to move up and down, the groove on the expansion element 03 is pressed inwards to deform, the pressing force on the contact surface of the expansion element 03 and the toy building element 01 is reduced during fixing, and therefore the effect that the expansion element can move in the groove horizontal direction of the toy building element 01 after the fixing connecting piece is fixed is achieved (as shown in fig. 11). In this feature, the groove 03F on the expanding element 03 only needs to be capable of inward pressing deformation, and the shape is not limited, and may be linear, T-shaped, and the like. In this case (as shown in fig. 11), the expansion element 03 is a linear groove, and when the fixed connection to the toy building element 01 is moved up and down in the direction shown in the figure, it is only necessary to press the groove in the fixed connection inwards and then move up and down.
The above are preferred embodiments of the present invention, and those skilled in the art can make various changes or improvements on the above embodiments without departing from the general concept of the present invention, and these changes or improvements should fall within the scope of the present invention.
