Abstract

The present invention relates to a frame for installing wooden bricks in which plural sections for holding the wooden bricks are arranged so as to correspond to the finished arrangement of the wooden bricks, a pederal for fixing the wooden bricks is prepared in each holding section, and a piece of elastic protrusion is protruded from a section wall of each holding section into an oblique downward direction in the section,

or a frame for installing wooden bricks in which, in addition to the above, on a wide joint means between each holding section, plural elastic projections having the same level to the upper surface of the wooden bricks the upper end of which is held in the holding section are prepared,

by holding the wooden bricks which have corresponding size and shape to the holding sections and by installing the wooden bricks on sidewalks and the like, the pavement of wooden bricks having smooth road may be very easily obtained.

Further, the pavement of wooden bricks having water permiability and permitting the expansion and contraction may be obtained.

Claims

1. A frame for installing wooden paving blocks, comprising:

a plurality of juxtaposed sections and each having a peripheral shape for holding a wooden paving block, said sections being arranged in a predetermined pattern, each of said plurality of sections being defined by a peripheral wall;

fixing means provided in each section for fixing a wooden paving block in the section, the peripheral wall for the section extending upwardly above said fixing means to a height such that when a wooden paving block is in position in a section, it will project at least slightly above the peripheral wall of the section; and

an elastic protruding piece provided around at least a portion of the peripheral wall of each section, said protruding piece projecting downwardly and inwardly into the interior of the section and having a free end spaced from the inner surface of the peripheral wall which is resiliently movable toward and away from the inner surface of the peripheral wall for being engaged by the edge of a wooden paving block positioned in the section and moving resiliently for accommodating changes in the shape of a wooden paving block in the section.

2. A frame as claimed in claim 1 in which said fixing means comprises a circular support member provided substantially in a center of the bottom of each of said plurality of sections, and arms connected between said circular support member and the peripheral wall of the section, said arms having spaces therebetween opening out of the bottom of the section, said circular support member having a hole therethrough for inserting a screw therethrough into a wooden paving block for securing a wooden paving block in the section.

3. A frame as claimed in claim 1 in which said frame is integrally molded from a resilient plastic.

4. A frame as claimed in claimed in claim 1 in which said protruding pieces each have a water drainage hole therethrough.

5. A frame as claimed in claim 1 in which said sections are rectilinear in shape, and are juxtapositioned in a pattern which is rectilinear, the portions of the peripheral walls of the juxtaposed sections around the outer periphery of the pattern constituting an outer wall.

6. A frame as claimed in claim 5 in which the thickness of said outer wall is half the thickness of the remainder of the peripheral walls.

7. A frame as claimed in claim 1 in which said sections are round in shape and said frame further comprises an outer wall having a rectilinear shape and surrounding said sections.

8. A frame as claimed in claim 7 in which said frame has spaces between said sections and between said sections and said outer wall, and said frame further comprises upwardly extending elastic projections in said spaces which extend upwardly to the same level as the upper surface of wooden paving blocks in said sections.
