Abstract

Claims (27)

1. A kit for constructing a craft, comprising:

a plurality of blocks, each block having a main body having an exterior surface that is made from a material that is adherent when exposed to water so as to permit a first block from the plurality of blocks to be adherable to a second block of the plurality of blocks by applying water to at least one of the first and second blocks,

each block further including a top surface and a block projection extending from the top surface,

each block further including a bottom aperture extending into the main body towards the top surface, and defining a longitudinal axis,

wherein the bottom aperture includes a first aperture region that has a plurality of first region sidewalls, which are connected to one another by a plurality of first region corners each having a first average radius, wherein the first aperture region is shaped to receive the block projection of the second block of the plurality of blocks, and

wherein the bottom aperture includes a second aperture region that has a plurality of second region sidewalls, which are connected to one another by a plurality of second region corners each having a second average radius that is greater than the first average radius.

2. The kit as claimed in claim 1 , wherein the second region sidewalls progressively increase in thickness with increasing distance from the second region corners.

3. The kit as claimed in claim 1 , wherein the second aperture region is shaped to receive a distal portion of a block tray projection on a block tray.

4. The kit as claimed in claim 3 , wherein the first aperture region is shaped to receive a proximal portion of the block tray projection.

5. The kit as claimed in claim 4 , wherein the bottom aperture includes a shoulder between the first aperture region and the second aperture region that defines a depth of the first aperture region, wherein the depth of the first aperture region is selected such that the shoulder is positioned to engage a limit surface on the block tray to hold a lowermost surface of one of the plurality of blocks above a floor of the block tray that surrounds the block tray projection.

6. A kit for constructing a craft, comprising:

a plurality of blocks, each block having a main body having an exterior surface that is made from a material that is adherent when exposed to water so as to permit a first block from the plurality of blocks to be adherable to a second block of the plurality of blocks by applying water to at least one of the first and second blocks,

each block further including a top surface and a block projection extending from the top surface,

each block further including a bottom aperture extending into the main body towards the top surface, and defining a longitudinal axis,

wherein the bottom aperture includes a first aperture region that is shaped to receive the block projection of the second block of the plurality of blocks, and

wherein the bottom aperture includes a second aperture region that is shaped to receive a distal portion of a block tray projection on a block tray,

wherein the first aperture region is shaped to receive a proximal portion of the block tray projection,

wherein the bottom aperture includes a shoulder between the first aperture region and the second aperture region that defines a depth of the first aperture region, wherein the depth of the first aperture region is selected such that the shoulder is positioned to engage a limit surface on the block tray to hold a lowermost surface of one of the plurality of blocks above a floor of the block tray that surrounds the block tray projection.

7. The kit as claimed in claim 6 , wherein the first aperture region is sized to have a first minimum clearance relative to the proximal portion of the block tray projection, and the second aperture region is sized to have a second minimum clearance relative to the distal portion of the block tray projection, wherein the first minimum clearance is smaller than the second minimum clearance.

8. A kit for constructing a craft, comprising:

a plurality of blocks, each block having a main body having an exterior surface that is made from a material that is adherent when exposed to water so as to permit a first block from the plurality of blocks to be adherable to a second block of the plurality of blocks by applying water to at least one of the first and second blocks,

each block further including a top surface and a block projection extending from the top surface,

each block further including a bottom aperture extending into the main body towards the top surface, and defining a longitudinal axis,

wherein the bottom aperture includes a first aperture region that is shaped to receive the block projection of the second block of the plurality of blocks, and

wherein the bottom aperture includes a second aperture region that is shaped to receive a distal portion of a block tray projection on a block tray,

wherein the first aperture region is shaped to receive a proximal portion of the block tray projection,

wherein the first aperture region is sized to have a first minimum clearance relative to the proximal portion of the block tray projection, and the second aperture region is sized to have a second minimum clearance relative to the distal portion of the block tray projection, wherein the first minimum clearance is smaller than the second minimum clearance.
