INTERLOCKING BUILDING ELEMENTS /CONSTRUCTION BLOCKS USING SPRING ACTION SN.&P MECHANISM
TECHNICAL FIELD
This invention relates to the interlocking building elements/ construction DIOCKS using spring action snap me hanism.
BACKGROUND OF THE INVENTION
The conventional blocks usually used in making toys or fun games etc. are mostly made of wood or plastic material. V ereas, wυod in its nature looks dirty and also gets dull upon use with the passage of time, while plastic is not eco friendly.
Dif±erent types of blocks which are available in the market canno be properly tightened. After some time they loose grip due to wear & tear.
The current invention lends itself advantageously, but with simpler elements with other known construction toys. The device of the present invention has unique features which enhances the performance of the building elements and construction blocks in particular.
OBJECTS OF THE INVENTION
The object of the present invention is to create such type of blocks which can easily be combined/assembled. i
Λnothej object o the invention is to provide tight grip among αi±±erent elements so that alter gripping, the different elements do not become loose.
Still another object of the invention is to have the combination of different elements having facility of rotation up to 360°.
Another object of the invention is to accommodate snapping mechanism on all structural elements.
SUMMARY OF THE INVENTION
The present invention allows the use of plurality of materials such as Steel, Aluminum, Brass, Plastic and the like to form a configuration. Generally, materials which are light in weight are to be used so that they can be properly handled. These blocks can be used as toy blocks for children. Different shapes and configuration can be made such as cars, planes, huts, buildings, trains, robots, cathedrals etc., depending on the imagination of the child. These blocks can easily be used by architects also to make models of their proposed buildings. They can also be used by engineers/industrial designs for the purposes of modeling as well.
These blocks are so designed that when they are interlocked, cannot be easily dismantled on account of the snap mechanism which has a tight grip between them. They can only be taken apart when slight pressure is applied with finger to enable the spring to release the male member.
T ώ material known to be most suitable for making elements is alloy oi aluminum wnicn couiα be easiiy pressure die casted/extruded, since the alloy of aluminum has a reasonable degree of strength for proper functioning and for 5 riveting of the snap action mechanism where ever required. As well as it allows to form various composite structures at limited cost.
Accordingly this invention relates to interlocking building blocks characterizing the use of spring action mechanism
-jO comprising structural elements; said elements having male and female snap action mechanism, where in said female snap action mechanism having recesses accommodating expandable spring with two arms of the spring protruding inwardly in said female receptacle to receive male snap action mechanism
15 thereby interlocking the joint means provided to allow 360° rotation along the axis of snap action mechanism between male snap actio mechanism and female snap action mechanism wherein the male snap action mechanism having a recess throughout the diameter of the upper half to allow the
20 spring to come back to its original position, thereby interiockinq the joint.
Another aspect of the invention is to accommodate snapping mechanism on all the structural elements. The female snapping mechanism is provided with an expandable spring
25 with two arms of the spring protruding inwardly in the female receptacle. When the male snapping mechanism is snapped/pushed with the pressure of the fingers the spring opens to accommodate the male snapping mechanism. Once the mechanism is totally interlocked, the spring comes to its 0 original position, thereby preventing the release, without the use of pull force. The spring comes back to its original
position because of a recess provided in the male snap mechanism throughout the diameter of the male snap action mechanism.
At the time of release a similar action takes place whereby the spring is pushed outwards due to the pull force and results in disengaging the snap mechanisms.
Another aspect of the invention is to have the plurality of radially receiving and engaging portions of other elements to form a configuration. Yet another aspect of the invention is that, plurality of material can be used as the interlocking of the blocks is only dependent upon the snap mechanism and not the material involved. Yet another aspect of this invention is. to provide for a locking arrangement of the elements when the elements are along their axial axis. Yet another aspect of this invention is to allow rotation of elements along the axis of the snap mechanism as per the requirement. Should the rotation be not desired the elements can be made static with each other by having two or more snap mechanism between them. However, should completely free and unrestricted rotation be desired between the two elements, free rotating shaft with male snap mechanism on either end of the shaft can be used. The shaft in this mode is placed between two holes of the element where the holes are of a larger diameter than the male snapping mechanism and the shaft which has the male snapping mechanism on either end.

Figure 1 shows the square shape of element 1 in which both upper half of male snap action mechanism 20 and the upper half of the female snap action mechanism 16. 22 is a female cavity in which the female member sits on any element, 17 is lower half of the female snap mechanism, 19 is the lower half of the male member. The female snap action mechanism has a spring 18 fitted on to it. Figure 2 shows a different shape that is a rectangular element having the same male & female members. In Figure 3 the combination of element 1 and 2 is shown. It shows the male snap action mechanism fitment with the female snap action mechanism. In Figures 4, 5, 7, 8, 12, 13, 15, 16, 18, 19, 21, 22, 24 the different con iguration of elements is shown having male & female snap action mechanisms. Figure 9 is a side view of the element 6, a cylinder having male and female snap mechanism radially. Figure 10 shows the element 6 with a male snap mechanism axially. Figure 11 shows how the cylindrical structural element 6 is engaged with element 5.
Figure 13 shows how the structural element 7 which is in the shape of hexagon is having male S. female elements and figure

frim l ftnaj mechanism in detail with the position of the spring 18 explicitly shown in this drawing. Figure 31 clearly shows how the male member is riveted along with the element 2. The lower half of male snap mechanism 19 5 is joined with upper half 20 of the male snap mechanism by a pressing riveting action at 23.
It should be understood that the forms of the invention shown are representative only, as certain changes may be required without departing from the text of this disclosure. ■jO For example spring like snap mechanism may be replaced with snap mechanism made of resilient material, not being spring m totality. Likewise the snap action mechanism can be replaced by any kind of bearing, to perform a similar job of a 360° rotation.
