The present invention is a block including a hollow housing within which a cylindrical container is loosely received and retained against axial motion relative to the housing. A hook supporting shaft is inserted within this container and the shaft is axially slidable relative to the container within predetermined limits. A shock absorbing mechanism within the container dampens the sliding motion of the shaft. The last named mechanism may include a dashpot with a dashpot housing mounted to the sh...

A block includes a hole provided on one side of the block, two fifths of the length of the block from one end, and a pin provided on the opposite side of the block two fifths of the length of the block from the other end. The hole is arranged to be connected to the pin of a like underlying or overlying block, so that a plurality of said blocks can be connected to form a double helix. Each end of the block includes a knob for connecting a plurality of blocks to a flexible member which follows a d...

A building block for use in building a structure consisting of linear or stepped courses of a plurality of blocks is designed such that any two types are required, a full block and a half block. Each full or half block consists of a substantially parallel piped body having upper and lower faces, opposed side walls and opposed end walls. The side walls and the end walls define a central cavity and the blocks are arranged to receive similar blocks in overlying and underlying relationship. The oute...

A block for a building or a pavement is disclosed which has a plurality of longitudinal holes and transverse holes extending through the block and communicating with each other at the intersecting points, recesses formed on the underside thereof, and a plurality of holes extending vertically through the block at the solid portions remaining between the intersecting points of the holes.

A block according to the present invention is a block comprising a base body part, a first protruding part, and a second protruding part, which are integrally formed with each other. The base body part has a left lower side face, a right lower side face, a left upper side face, and a right upper side face formed as respective sloping faces. The first protruding part has a lower surface thereof formed by first to third left-hand sloping faces, an upper surface thereof formed by fourth to sixth le...

A block unit for a block toy contains a block body having protrusions and recesses through which the block body is freely connectable to other block units; a rotary shaft rotatably supported in the block body in such a manner that the rotary shaft is extended in a block coupling direction in which the block unit is coupled to other block units through the protrusions and recesses thereof; and a rotation transmitting mechanism for transmitting the rotation of the rotary shaft to other block bodie...

A block set having a plurality of individual units, each unit consisting of two identically proportioned U-shaped elements joined together at one leg of each element so that the exterior dimensions of the unit are in the form of a cube.

A heat transferring device adapted for use in a thermoelectric generator which automatically compensates for shock, vibration, and thermal expansion is disclosed. The device consists of a relatively solid block composed of four slideably moveable wedges arranged in opposing pairs so that the movement of one pair of wedges together causes the other pair of wedges to move apart, one pair of opposing wedges being provided with means biasing them together.

A block system useful as a puzzle or game consisting of a group of solids adapted to be assembled into a larger regular polyhedron. The solids each have shapes that are determined by an assembly of components that include a tetrahedron and one or more fractional sections of an octahedron. The fractional sections comprises one-eighth and one-fourth sections of a regular octahedron.

A marine block useable with other similar marine blocks in constructing marine structures such as groins, breakwaters, seawalls and seawall armor. The blocks are used in constructing structures in an arranged condition in which they are keyed together and may be disposed in a random arrangement. Each block is constructed as two massive, end cylinders of circular cross section joined together integrally by a center cylinder of lesser mass and diameter than the end cylinders. The end cylinders are...
