Abstract

Building sets including a plurality of blocks and a plurality of clips configured to engage a thickness of one or more of the blocks. Each clip includes a base and first and second substantially parallel extensions extending from the base and defining a channel therebetween into which a thickness of a block is receivable. The width of the channel is substantially equal to and slightly less than the thickness of the block receivable within the channel so that the thickness is frictionally retained therein. The clip may include a magnet enclosed within the base so that the base of a first clip may be magnetically coupled to the base of another clip, and each clip may in turn be frictionally coupled to a block received between the extensions of the respective clip. In one embodiment, the clip includes a plurality of channels.

Claims

1. A toy clip for frictionally engaging a thickness of one or more building blocks, the clip comprising:

a planar u-shaped receiver formed entirely of contiguous planar surfaces, the planar u-shaped receiver including;

at least a base defining a planar floor surface; and

a pair of extensions extending from the base to a pair of lateral edges, the extensions each forming a planar interior surface, wherein the planar floor surface and the planar interior surfaces of the extensions combine to define a channel having a proximal portion adjacent to the planar floor surface and a distal portion adjacent to the lateral edges, the channel having a variable width according to a location along or between the proximal portion and the distal portion, the variable width of the channel configured to retain the thickness of at least one of the building blocks via only a frictional fit.

2. The toy clip of claim 1, wherein the variable width of the channel is defined by one or more discontinuities along the planar interior surfaces of the extensions.

3. The toy clip of claim 2, wherein the one or more of the discontinuities along the planar interior surfaces of the extensions comprise frictional features along the planar interior surfaces of the extensions.

4. The toy clip of claim 3, wherein the frictional features along the planar interior surfaces of the extensions are formed by differing angles between the planar interior surfaces and the planar floor surface at the proximal and the distal portions of the channel.

5. The toy clip of claim 4, wherein the proximal portion and the distal portion combine to form a first portion adjacent to the planar floor surface, a second portion adjacent to the first portion, a third portion adjacent to the second portion, and a fourth portion between the third portion and the lateral edges.

6. The toy clip of claim 5, wherein the channel has respective first, second, third, and fourth widths at the first, the second, the third, and the fourth portions of the channel.

7. The toy clip of claim 6, wherein the planar interior surfaces of the extensions form respective first, second, third, and fourth angles relative to the planar floor surface at the first, the second, the third, and the fourth portions of the channel.

8. The toy clip of claim 7, wherein the first angle is approximately 90 degrees, the second angle is less than 90 degrees, the third angle is approximately 90 degrees, and the fourth angle is greater than 90 degrees.

9. The toy clip of claim 1, wherein the extensions extend outward from the base to the lateral edges.

10. The toy clip of claim 1, wherein:

the base is disposed about a central body;

one or more additional bases are disposed about the central body; and

an additional pair of extensions extend from each of the additional bases to form one or more additional channels about the central body.

11. A toy clip for engaging one or more building blocks, comprising:

a number of planar u-shaped channels disposed about a central body, each of the channels formed entirely of contiguous planar surfaces and defined by a base forming a planar floor surface and by respective first and second extensions that form first and second planar interior surfaces extending outward from the planar floor surface to first and second lateral edges, wherein;

a width separates the first and the second planar interior surfaces, the width configured for frictional retention of one or more of the building blocks; and

the width separating the first and the second planar interior surfaces varies according to a location between the planar floor surface and the first and the second lateral edges.

12. The toy clip of claim 11, wherein one or more elevation discontinuities along at least one of the first and the second planar interior surfaces cause the width separating the first and the second planar interior surfaces to vary according to the location between the planar floor surface and the first and the second lateral edges of the channel.

13. The toy clip of claim 12, wherein the one or more of the elevation discontinuities form a pinch point in the width separating the first and the second planar interior surfaces of the first and the second extensions.

14. The toy clip of claim 13, wherein the one or more of the elevation discontinuities comprise one or more frictional protrusions that extend toward a center of the channel.

15. The toy clip of claim 14, wherein:

the channel comprises a first portion adjacent to the planar floor surface, a second portion adjacent to the first portion, a third portion adjacent to the second portion, and a fourth portion between the third portion and the first and the second lateral edges;

the first and the second planar interior surfaces at the first portion are formed perpendicular to the planar floor surface;

the first and the second planar interior surfaces at the second portion are formed at an inward angle of less than 90 degrees;

the first and the second planar interior surfaces at the third portion are formed perpendicular to the planar floor surface;

the first and the second planar interior surfaces at the fourth portion are formed at an outward angle greater than 90 degrees;

each of the first and the second planar interior surfaces defines a first intersection where the second portion meets the third portion and a second intersection where the third portion meets the fourth portion; and

the first and the second intersections define the one or more of the frictional protrusions.

16. A connecting joint for a toy building set, consisting of:

a toy building block having a fixed thickness; and

a toy clip defining a planar u-shaped channel formed entirely of contiguous planar surfaces, the planar u-shaped channel defined by a base forming a planar floor surface and respective first and second extensions that extend outward from the base to first and second lateral edges, the first and the second extensions having first and second planar interior surfaces, the planar u-shaped channel having a varying width that is configured to engage the toy building block via a frictional fit.

17. The connecting joint of claim 16, wherein:

the varying width of the channel comprises at least one pinch point along the first and the second planar interior surfaces of the first and the second extensions.

18. The connecting joint of claim 17, wherein the at least one pinch point comprises an elevation discontinuity along at least one of the first and the second planar interior surfaces.

19. The connecting joint of claim 18, wherein the elevation discontinuity comprises a frictional protrusion formed along the at least one of the first and the second planar interior surfaces.

20. The connecting joint of claim 19, wherein the channel is disposed about a central body of the toy clip.
