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

TECHNICAL FIELD 
The present invention relates to frames for installing wooden bricks with 
which roads through parks, pavements along public roads, road surfaces of 
parking places, roads used in meeting places to be held entertainment 
temporarily, and other roads are paved. The wooden bricks are installed on 
the ground of the said roads and held with the frames, and pavement of 
wooden bricks is built. 
BACKGROUND ART 
Hitherto, pavements used wooden bricks are sometimes observed in malls 
where pedestrians can freely walk, on roadways at special time, in parks, 
in gardens and the like. 
Such pavement of wooden bricks are installed by the following methods. 
In the first method, the ground is almost leveled by coating void kneading 
mortar, wooden bricks are placed on the ground at suitable spaces, and the 
wooden bricks are evenly knocked with a wooden hammer and the like to 
level the surface of the wooden bricks and to cover some of the lower part 
of the wooden bricks with the mortar. Molten asphalt is then poured into 
each joint of the wooden bricks, the asphalt is hardened, and sand is put 
on the asphalt. 
In the second method, asphalt primer is applied on the concrete ground 
which is evenly finished by coating with leveling mortar, a solution of 
blown asphalt is applied on the ground before plural wooden bricks are 
placed on the ground at suitable spaces in good order one by one, the 
solution of blown asphalt is then poured into each joint of the wooden 
bricks, the asphalt is hardened to obtain joint completion. In this 
method, when the wooden bricks are installed on the ground, there is no 
doubt that the wooden bricks should be evenly knocked with a wooden hammer 
and the like to level the surface of the wooden bricks. 
However, these methods for installing the wooden brick pavement have many 
problems and cannot fit for practical use. Operations for installing the 
wooden bricks in the first and the second methods described above are 
conducted by placing many wooden bricks one by one and by knocking the 
surface to arrange the bricks, so that the operations are extremely 
inefficient. Furthermore, it is difficult to obtain the flat surface of 
the pavement. As the wooden bricks are arranged by eye measurement, there 
is a problem in which it is difficult to make even the joint width between 
each wooden brick. 
Moreover, in the usual installation of wooden bricks as described above, as 
the wooden bricks are fixed on the ground with mortar or asphalt and 
joints are fixed with mortar or asphalt, rainwater and the like cannot 
permeate underground, and there is a problem in which pools are easily 
formed on the wooden brick pavement. As the result, corrosion of the 
wooden bricks is induced. Furthermore, as the wooden bricks are fixed with 
asphalt and the like as described above, the change of expansion of the 
wooden bricks caused by containing water and contraction of the dehydrated 
wooden bricks cannot be absorbed. 
Thereupon, it has been disclosed that plural wooden bricks are arranged in 
fixed order, and wooden bricks are joined together by filling joint 
materials such as asphalt, acryl type rubber, urethane type rubber and the 
like between their gaps to form the board like complex of wooden bricks 
(Unexamined Publication of Japanese Patent Application Number, 
59(1984)-(1006). 
Furthermore, it has been disclosed that plural wooden bricks are joined 
together to arrange in a row as described above by using joint materials 
which are obtained by mixing resin and rubber chips, and the joints have 
apertures passing through the both sides (Unexamined Publication of 
Japanese Utility Model Application Number, 61(1986)-19(2010). 
However, problems of the former method are that the joint materials have no 
water permeability when roads and the like are paved by this method, 
rainwater and the like cannot permeate underground, and pools are easily 
formed on the wooden brick pavement, as the result, the wooden bricks are 
corroded. Further, as the joint materials cannot keep sufficient 
pliability, the method cannot enough coped with the expansion and 
contraction of wooden bricks caused by humidity changes. There is also a 
very important problem in which the process for attaching the wooden 
bricks to the joint materials is difficult. 
The latter method is aimed to settle the problem of water permeability, 
however, so far as the above constitution is concerned, it will be 
practically difficult to keep the water permeability, and the joint 
process of wooden bricks with joint materials is difficult like the former 
method. 
Accordingly, an object of the present invention is to provide a frame for 
installing wooden bricks which is separated from the wooden bricks and can 
easily fit to the wooden bricks. 
Another object of the present invention is to provide a frame for 
installing wooden bricks which can enough coped with the expansion and 
contraction of wooden bricks caused by humidity change when the wooden 
bricks are held to the frame to install on a sidewalk and the like. 
Furthermore, another object of the present invention is to provide a frame 
for installing wooden bricks which can keep water permeability when the 
wooden bricks are held to the frame to install on a pavement and the like. 
The other object of the present invention is to provide a frame for 
installing wooden bricks in which splits of the wooden bricks can be 
prevented by flexibly fixing the bricks so as to admit their deformation 
in a certain extent, when the wooden bricks are held to the frame to 
install on a road and the like, even though the road is pressed by 
pedestrians or cars. 
Additionally, another object of the present invention is to provide a frame 
for installing wooden bricks having a means which can fill up wide joint 
gaps between the wooden bricks, because the gaps are produced by uneven 
plane configuration of the wooden bricks to be held. 
DISCLOSURE OF INVENTION 
The first invention is 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 means 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. 
The second invention is 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 means for 
fixing the wooden bricks is prepared in each holding section, a piece of 
elastic protrusion is protruded from a section wall of each holding 
section into an oblique downward direction in the section, and, 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. 
The above holding sections can be constituted in several kinds of size and 
configuration corresponding to the wooden bricks to be held. As the plane 
configuration of wooden bricks, a quadrangle such as a square and a 
rectangle, a circle and the like are common, so that the holding sections 
can be constituted so as to hold the wooden bricks having a kind of 
configuration or combination of plural kinds of configuration in 
appropriate arrangement. 
As an example, when the plane configuration of the aimed wooden bricks are 
a square, plural holding sections, such as nine holding sections are 
constituted in three perpendicular and three lateral lines, respectively. 
In this case, by forming section plates of lattice, the holding sections 
can be constituted in the perpendicular and lateral arrangement as 
described above. In such constitution, each corresponding part of the 
above section plate is a section wall of each holding section, the section 
wall is owned jointly at the adjacent holding sections. This is a 
fundamental arrangement of the wooden bricks. 
For example, an installing frame in which holding sections of wooden bricks 
having plane circular configuration are arranged in perpendicular and 
lateral lines as described above can be constituted. In this case, the 
section wall is constituted in a plane ring-shaped surrounding wall. The 
outer circumference of the wall is connected with outer circumference of 
an adjacent section wall by using a suitable connection means. The 
suitable connection means is a connection plate which is integrally molded 
with the section wall. 
Furthermore, for example, an installing frame can be constituted by 
arranging about three lines of holding sections which hold wooden bricks 
having plane rectangular form so a to contact at the longitudinal side. 
Then, the above means for fixing the wooden bricks also can be mainly 
constituted by a holder on which the wooden bricks are placed. This holder 
is constituted as a stand which is partly standing up from the lowest part 
of the holding section. Further, the holder is constituted so as to have a 
little high edge on the upper surface. The inside of the holder has 
relatively a little low plane part. One or about two screw holes passing 
through two sides of the inside plane part are made. Furthermore, 
preferably, one or more small holes are made around the hole. When the 
holding section has a plane configuration of a square or a circle, a 
holder is suitably constituted in the center. When the holding section has 
a plane configuration of a rectangle or the like, plural holders are 
suitably arranged at proper interval in proportion to the length. Then, 
the above holder is constituted so as to be held by plural arms which 
extend near the lower part of the section walls of the holding section. 
Moreover, plates for preventing sinking of wooden bricks may be 
horizontally projected at the lower inside of the above section walls, 
around the lower part of the holder and at the lower sides of the above 
arms. 
Further, the above protrusion piece is constituted, for example, in the 
downward direction from the top of section walls to the section inside 
and, as described above, into an oblique downward direction. The angle 
between the protrusion piece and the section wall is not particularly 
limited, suitably about 25.degree.-35.degree.. The width of the protrusion 
piece is not particularly limited, suitably 1/3-1/4 of the thickness of 
the wooden brick. Commonly, the thickness is about 9-13 mm. The above 
protrusion piece is aimed to hold and elastically bind the wooden brick by 
contacting the lower edge of the protrusion piece to the outer 
circumference of the wooden brick which is inserted in the holding 
section. The above protrusion piece has, if necessary, a notch for 
penetrating water at suitable intervals. When rainwater and the like are 
penetrated between the installed wooden bricks, the notch can act to flow 
the water on the ground, and the water can be penetrated underground by 
constituting the ground of water penetration. As the rainwater and the 
like cannot stay around the wooden bricks by such constitution, their 
corrosion and the like can be prevented. 
Furthermore, in the second invention elastic projections are especially 
prepared on the wide connection means between the holding sections. The 
projections are especially used for the installing frames which hold 
wooden bricks having plane circular configuration. In this case, it is 
inevitable to form, at least in part, a wide gap between the holding 
sections. In the above gap, the connection means for connecting the 
adjacent holding sections, for example the connecting plate, is 
constituted, and plural elastic projections are prepared on the connection 
means. These elastic projections are constituted in pipe form passing 
through the plate, and the form is suitable from the point of view of 
water penetration. 
Further, around the installing frames of wooden bricks, in any case, male 
and female joining means are, if necessary, constituted for joining the 
adjacent objects when the bricks are installed. 
Moreover, these installing frames are suitably formed by using plastic 
materials having enough strength. As the materials, polypropylene and the 
like are suitable. 
The installing frames of this invention are constituted as described above 
and can be used for pavements such as sidewalks by holding wooden bricks 
as follows. The wooden bricks are previously applied antiseptic treatment. 
At the beginning, the wooden bricks having plane configuration are inserted 
into each of the holding sections as expected. The wooden bricks are 
inserted by pressing from the top in the installing frame which is placed 
upward. As the protrusion pieces are constituted obliquely downward at the 
surrounding walls of the holding sections and elastically, when the wooden 
bricks are pressed into the holding sections as described above, with the 
bricks descending, the protrusion pieces go back to the section walls and 
the wooden bricks are smoothly inserted into the holding sections. If 
dimensions of the wooden bricks are slightly larger or smaller, some 
difference of the dimensions are absorbed by the above protrusion pieces. 
For example, even if the dimensions of the wooden bricks are slightly 
larger and the wooden bricks cannot be easily pressed, the bricks are 
struck with a wooden hammer and the like. 
After the wooden bricks are inserted in the whole holding sections of the 
installing frame, for example, when a fixing means is constituted as a 
holder having a vis hole as described above, the installing frame is 
turned inside out, a vis is inserted in the vis hole and screwed on the 
lower part of the wooden brick. This operation can be efficiently 
conducted by using an electric driver and the like. 
By repeating such insertion work of the wooden bricks, necessary numbers of 
each wooden brick can be inserted in each holding section of the 
installing frame and fixed. 
Then, the installing construction of a necessary installing zone such as a 
sidewalk and the others begins by building a suitable groundwork of 
gravel, concrete and the like. 
The above gravel ground is smoothly finished by digging the necessary zone 
about 300 mm deep, graveling and pressing the zone sufficiently. Further, 
the digging depth is not limited to the above value. The concrete ground 
can be obtained by digging the necessary zone similarly, concreting the 
zone by a general method and smoothly finishing the surface. 
On the gravel or concrete ground as described above, the installing frames 
holding the above wooden bricks are provided perpendicularly and 
laterally. When joining means are constituted around the installing 
frames, the adjacent installing frames are mutually joined by these 
joining means. By conducting such operations throughout the necessary 
zone, the installation is finished. 
Accordingly, the smooth pavement of wooden bricks can be very easily and 
efficiently conducted by a non-professional by continuously joining the 
installing frames. 
Furthermore, as the wooden bricks installed as described above are inserted 
in the holding sections of installing frames and the surrounding sides are 
held by protrusion pieces which are protruded from the section walls, the 
wooden bricks can advantageously act in many ways even after the 
installation. 
Firstly, as the above protrusion pieces have elasticity, these pieces can 
absorb expansion and contraction of wooden bricks caused by humidity 
change. 
Secondly, as the wooden bricks are elastically held by the protrusion 
pieces as mentioned above, even if various shocks are given from the 
outside by running cars or by walking pedestrians on the installing road 
surface, the deformation of wooden bricks is within the limits of retreat 
of the protrusion pieces, so that the deformation beyond the limits is 
prevented and especially cracks which are easily caused along the grain of 
a corner and the like are prevented. 
In the pavement of wooden bricks installed in such a manner, water 
permeability can be secured. 
The above description is applied to both the first and the second 
inventions. In the second invention, when a bigger gap is formed between 
the holding sections, especially when the installing frames contain the 
holding sections of wooden bricks having plane circular configuration, 
this constitution is very useful. Namely, as many elastic projections are 
provided on the connection means between the holding sections, even if a 
gap is formed, it is able to walk or run on the bricks without the least 
inconvenience. As described above, when the elastic projections are shaped 
into a tube, water permeability becomes good.

BEST MODE FOR CARRYING OUT THE INVENTIONS 
For illustrating the present inventions more specifically, examples are 
described below while referring to the drawings. 
The first example of one of the present inventions is explained. 
As shown in FIG. 1, an installing frame in which nine holding sections 1, 1 
. . . having plane squares are arranged in three perpendicular and three 
lateral lines is constituted. 
The above holding sections 1, 1 . . . are surrounded by section walls 2, 2, 
2, 2, these section walls 2, 2 . . . are constituted in common with those 
of mutual adjacent holding sections 1, 1, respectively, and the section 
walls 2, 2 . . . which are situated so as to form the outer walls of the 
installing frame are constituted in common with the outer walls of the 
installing frame. Accordingly, the holding sections 1, 1 . . . are 
constituted in lattice sections which are constituted by a group of three 
section walls 2, 2, 2 which are arranged in four perpendicular lines and a 
group of three section walls 2, 2, 2 which are arranged in four lateral 
lines. 
Further, in the above section walls 2, 2 . . . , the walls in common with 
the outer walls of the installing frame are formed in 2 mm thick and the 
other walls are formed in 4 mm thick. In this case, as described later, 
when installing frames holding wooden bricks b-1, b-2 are jointly arranged 
at a certain area, the distance between the wooden bricks b-1, b-1 which 
are contacted at the mutual adjacent outer wall of the installing frame 
becomes equal to the distance between the wooden bricks b-1, b-1 in the 
installing frame. 
Then, the above installing frame, as shown in FIG. 1 and FIG. 3, is 
constituted in a plane square having a side of 330 mm and a height of 40 
mm. The sides of the above holding sections 1, 1 . . . are 110 mm long. 
Further, the latter length shows distance between the central points of 
the section walls 2, 2 on both sides. Concerning the distance from the 
section wall 2 in common with the outer wall of the installing frame to 
the inside section wall 2, the distance from the side in common with the 
outer wall does not show the distance from the central point but shows the 
distance from the outside. 
As shown in FIGS. 1 to 3, protrusion pieces 3, 3 are protruded from the 
upper end of the section walls 2, 2 . . . of four sides of the above 
holding sections 1, 1 . . . into oblique inside and downward directions of 
the sections by having little openings at the both sides. The angle 
between the protrusion pieces and the section walls 2, 2 . . . is about 
30.degree.. The above protrusion pieces 3, 3 . . . have a protruded width 
of 10 mm. As the result, the above protrusion pieces 3, 3 . . . extend to 
the inside of the holding sections 1, 1 . . . in 5 mm wide. Further, the 
above protrusion pieces 3, 3 . . . have notches 4, 4 for penetrating water 
at two places, respectively. 
Moreover, at the central lower part of the above holding sections 1, 1 . . 
. especially as shown in FIG. 1, FIG. 2 and FIG. 4, a holder 5 of each 
wooden brick is arranged, respectively. The above holders 5, 5 . . . are 
formed in a circle stand by standing up from the bottom of the holding 
sections 1, 1 . . . in 10 mm high. Then, the top of the holders 5, 5 . . . 
has a circular plane part 6 inside of the surrounding edge in 1 mm high, 
respectively. At the center of the above circular plane part 6, 6 . . . , 
a vis hole 7 is formed so as to pass through two sides of the plane part. 
Further, around the vis hole, two little binding holes 8, 8 are made in a 
straight line with the above vis hole 7. The above holder 5, as shown in 
FIG. 1, is held by extending each arm 9 from four inner corners of the 
holding section 1. 
Moreover, around the lower part of the above holders 5, 5 . . . , on both 
sides of the lower part of the above arms 9, 9 . . . and at the lower 
inside of the above section walls 2, 2 . . . a protrusion 10 for 
preventing sinking of wooden bricks is horizontally projected, 
respectively. 
Then, as shown in FIG. 1 and FIG. 2, on two adjacent sides which contain an 
angle and belong to four sides of the outer walls of the installing frame, 
two joining projections 11, 11 are protruded, respectively, and on the 
other two sides, joining holes 12, 12 corresponding to the above joining 
projections 11, 11 are constituted, respectively. The joining projections 
11, 11 of the side are formed on the section walls 2, 2 of the holding 
sections 1, 1 which are situated at corners of the installing frame. They 
are naturally constituted on the section walls 2, 2 in common with the 
same outer wall of the installing frame. As shown in FIG. 2, FIG. 4, FIG. 
5 and FIG. 7, the joining projections 11, 11 are projected from the outer 
walls of the installing frame so as to be situated slightly above the 
thickness of the protrusions 10, 10 . . . for preventing sinking of wooden 
bricks. The projection width is about 4 mm, slightly wider than the 
thickness of the outer wall, namely 2 mm. The thickness in a height 
direction is about 6 mm. Besides, as shown in FIG. 1 and FIG. 3, the 
length of the direction along the outer walls of the above joining 
projections 11, 11 . . . is determined to almost the same as the length 
between the notches 4, 4 for penetrating water of the protrusion pieces 3, 
3 . . . , namely about 45 mm. 
In addition, the above joining holes 12, 12 of the side of the outer wall 
of the installing frame correspond to the above joining projections 11, 
11, and they are constituted on the section walls 2, 2 of the holding 
sections 1, 1 which are situated at corners of the installing frame. As 
shown in FIG. 2, FIG. 4, FIG. 5 and FIG. 7, the joining holes 12, 12 are 
made at the outer walls of the installing frame so as to be situated above 
the thickness of the protrusions 10, 10 . . . for preventing sinking of 
wooden bricks. The height from the hole bottom of the joining holes 12, 12 
is slightly above 6 mm. Then, the length of the direction along the outer 
walls of the above joining holes 12, 12 is almost the same as the length 
between the notches 4, 4 for penetrating water of the protrusion pieces 4, 
4, namely slightly above 45 mm. 
Furthermore, the above whole constitution elements are integrally molded 
out of plastics which are obtained by mixing a main polypropylene 
material, and a weathering agent and the like. 
In this embodiment, as the installing frame is constituted as described 
above, as explained in the following, the frame can be used for the 
pavement of sidewalks and the like by holding the wooden bricks b1, b-1 . 
. . having plane square configuration to the holding sections 1, 1 . . . . 
Considering the size of the above installing frame, the wooden bricks b-1, 
b-1 which are formed in plane square shape having a side of 100 mm and a 
height of 40 mm are suitable for the holding object. Moreover, the above 
wooden bricks b-1, b-1 are naturally applied antiseptic treatment by 
permeating an antiseptic or by the other method. 
Before the installing frame is installed on sidewalks and the like, the 
wooden bricks b-1, b-1 . . . are inserted and held in the holding sections 
1, 1 . . . , respectively. 
The wooden bricks b-1, b-1 . . . , as shown in FIG. 1, are placed upward, 
and successively pressed in the holding sections 1, 1 . . . from the top. 
As the protrusion pieces 3, 3 . . . of the section walls 2, 2 . . . , 
especially as shown in FIG. 2, FIG. 4, FIG. 5, FIG. 6 and FIG. 7, are 
constituted obliquely downward and they are molded out of plastics of 
which a main material is elastic polypropylene, with the pressing action 
of the wooden brick b-1 as described above, the lower edge goes back to 
the section walls 2, 2 . . . , and the wooden brick b-1 is smoothly 
inserted. When the insertion is a little hard, the brick can be struck 
with a wooden hammer and the like. By repeating this operation in the 
numbers of the holding sections 1, 1 of each installing frame, the wooden 
bricks b-1, b-1 can be inserted in each installing frame. 
Subsequently, the installing frame in which the insertion of the wooden 
bricks b-1, b-1 in the holding sections 1, 1 . . . are finished is turned 
inside out, a vis 3 is inserted in the vis hole 7 from the back of each of 
the holders 5, 5 . . . to screw on the wooden brick b-1 from the back, and 
the wooden brick b-1 is fixed on the holder 5. It is efficiently conducted 
by an electric driver to screw the vis 13 on the wooden brick b-1. FIG. 3 
shows the installing frame in which the wooden bricks b-1, b-1 . . . are 
held in the holding sections 1, 1 . . . , as described above. FIG. 4 shows 
a condition in which the wooden bricks b-1, b-1 . . . are fixed on the 
holder 5, 5 . . . by the vis 13, 13 . . . . 
The installation of sidewalks and the like is conducted by building the 
groundwork of gravel or concrete. 
In this embodiment, the gravel ground is built and the frames are installed 
on a sidewalk in a park. 
This gravel ground 14 is smoothly finished by digging down a certain zone 
in a depth of about 30 cm, graveling and pressing the zone sufficiently. 
On the above gravel ground 14, the installing frames in which the above 
wooden bricks b-1, b-1 . . . are held are arranged perpendicularly and 
laterally. This work is conducted by arranging the installing frames on 
the gravel ground 14 while the adjacent installing frames are connecting 
each other. The adjacent installing frames are mutually connected, for 
example, as shown in FIG. 5, by progressing one of the installing frames 
to the other installing frame as shown by an arrow, and by fixing the 
joining projections 11, 11 of the outer wall of one of the installing 
frames in the joining holes 12, 12 of the other installing frame. When the 
installing work is conducted throughout the fixed zone while the adjacent 
installing frames are mutually joined as described above, the construction 
is completed. In this way, the smooth pavement of the wooden bricks b-1, 
b-1 . . . can be completed by simple operation by which the installing 
frames are continuously arranged. FIG. 6 shows a part of the installing 
frame provided on the gravel ground 14 after the wooden bricks b-1, b-1 
are held. Further, FIG. 7 shows a mutually connected part of the adjacent 
installing frames which are laid on the gravel ground 14. 
Still more, it is not necessary to insert a filler in the joint between the 
wooden bricks which are installed by the installing frame, but if 
necessary, it is able to fill the joint with sand and the like. However, 
when the filler is inserted in the joint, it is necessary to investigate 
well the property of the filler so as to keep water permeability. 
By the way, in the wooden bricks b-1, b-1 . . . which are installed as 
described above, as shown in FIG. 3 and FIG. 4, as the surrounding sides 
are held at the lower edges of the protrusion pieces 3, 3 . . . which are 
obliquely and downward protruded from the section walls 2, 2 . . . of the 
holding sections 1, 1 . . . and as the protrusion pieces 3, 3 . . . 
themselves have elasticity, these pieces can absorb expansion and 
contraction of wooden bricks b-1, b-1 . . . caused by humidity changes. 
Further, as the deformation of the wooden bricks b-1, b-1, . . . is 
limited in the ranges of the holding sections 1, 1 . . . , even if various 
shocks are given from the outside by running cars or by walking 
pedestrians on the installed road surface, cracks which are easily caused 
along the grain are prevented. 
Further, in the pavement of the wooden bricks b-1, b-1 . . . using the 
above installing frame, as notches 4, 4 for penetrating water are formed 
on the protrusion pieces 3, 3 . . . which are provided on the section 
walls 2, 2 . . . of the installing frame, rainwater and the like can flow 
on the gravel ground 14 through these notches. As the gravel ground 14 is 
naturally water penetration, rainwater and the like can be penetrated 
underground. 
When a part of the wooden brick b-1 installed in the installing frame is 
damaged, the damaged wooden brick b-1 can be changed as follows. 
Firstly, a bar tip, a chisel tip, an edged tool and the like are thrust on 
the surface of the damaged wooden brick b-1, the wooden brick b-1 is 
cracked by striking their back with a hammer and the like, the vis 13 is 
loosened and the brick is taken out from the holding section 1. Then, the 
above vis 13 which is exposed on the surface of the holder 13 is struck 
down on the side of the gravel ground 14. After that, a binding agent is 
applied on a plane circular part 6 of the holder 5, and a new wooden brick 
b-1 is inserted in the said holding section 1. Thus, the binding agent 
adheres to the back of the wooden brick b-1, the wooden brick b-1 and the 
holder 5 are adhered and fixed in the holding section 1. The adherence of 
the binding agent to the plane circular part 6 is strengthened by 
overflowing excess binding agent from the back of the holder 5 through the 
little binding holes 8, 8, and by solidifying the overflowed binding agent 
in a globular shape having a longer diameter than the inside diameter of 
the little binding holes 8, 8. 
Then, the second example of one of the present inventions is briefly 
explained. 
As shown in FIG. 8, an installing frame having a plane square is 
constituted by arranging three lines of holding sections 21, 21, 21 having 
plane rectangular forms. 
The above holding sections 21, 21, 21 are surrounded by section walls 22, 
22 . . . , the section wall 22 between the mutual adjacent holding 
sections 21, 21 is constituted in common, and the section walls 22, 22 . . 
. which are situated so as to form the outer walls of the installing frame 
are constituted in common with the outer walls of the installing frame. 
Further, the above section walls 22, 22 which are constituted in common 
with the outer walls of the installing frame have a thickness of 2 mm and 
the other section walls 22, 22 have a thickness of 4 mm which is twice of 
the above thickness. As described later, when installing frames which hold 
wooden bricks b-2, b-2 having plane rectangular forms are jointly arranged 
at a certain area, the distance between the wooden bricks b-2, b-2 which 
are contacted at the mutual adjacent outer wall of the installing frame 
becomes equal to the distance between the wooden bricks b-2, b-2 in the 
installing frame. 
Then, the above installing frame, as shown in FIG. 8 and FIG. 11, is 
constituted in a plane square having a side of 330 mm and a height of 40 
mm. The length of short sides of the above holding sections 21, 21 . . . 
is 110 mm and the length of their long sides is 330 mm. Further, in the 
above size, the short sides show the distance from the center of one side 
of the section wall 22 to the center of the other side of the section wall 
22. Concerning the size of the section wall 22 which is in common with the 
outer wall of the installing frame and the inside section wall 22, the 
distance from the side in common with the outer wall does not show the 
distance from the center but the distance from the outside. Concerning the 
long sides, it shows the distance from the outside of outer wall to the 
outside of the other outer wall. Namely, this size is equal to the size of 
a side of the installing frame. 
As shown in FIGS. 8 to 12, a protrusion piece 23 are protruded downward in 
the section from the short side and three protrusion pieces 23, 23, 23 are 
protruded from the long side of four section walls 22, 22 . . . of the 
above holding sections 21, 21 . . . , respectively. The length of the 
protrusion pieces 23, 23 . . . is 70 mm in the direction of walls and the 
width is 10 mm in the protrusion direction. The angle between the 
protrusion pieces and the section walls 22, 22 . . . is 30.degree.. 
Accordingly, the length of protruded lower part is usually about 5 mm in 
the section. Then, the protrusion piece 23 of the short side is situated 
in the center of the section wall 22. Openings of 20 mm are left at the 
both sides. Moreover, in the long side, one protrusion piece 23 is 
arranged in the center of the section wall 22 and each protrusion piece 23 
is arranged at the both sides in the distance of 40 mm, respectively. 
Furthermore, in each of the above holding sections 21, 21, 21, plate frames 
24, 24 are arranged at the positions dividing into equal three parts in 
the section. As shown in FIG. 8, FIG. 10 and FIG. 13, these plate frames 
24, 24 is constituted in a frame form by connecting the both edges to the 
long sides of the section walls 22, 22. The height of the plate frames is 
10 mm and the width is 10 mm. 
Then, in each of the above holding sections 21, 21, 21, as shown in FIG. 8, 
FIG. 9, FIG. 10, FIG. 12 and FIG. 13, a holder 25 of each wooden brick b-2 
is arranged so as to be situated at the center lower part of three square 
zones which are divided by the above plate frames 24, 24. The above 
holders 25, 25 . . . are pedestals having a height of 10 mm and standing 
up from the bottom of the holding sections 21, 21. Namely, the height of 
the pedestals is equal to the height of the above plate frames 24, 24. 
Further, the upper surface of the above holders 25, 25 . . . have plane 
hollows 26, 26 . . . of which surrounding edges are left and the height is 
about 1 mm. As the result, the configuration of the above plane hollows 
26, 26 . . . , as shown in FIG. 8, is similar to the plane configuration 
of the holders 25, 25 . . . . Two vis holes 27, 27 are passed through from 
the upper surface to the under surface of the above plane hollows 26, 26 . 
. . . Further, as shown in FIG. 8, eight arms 29, 29 . . . are protruded 
from the outer surroundings of each of the above holders 25, 25 at regular 
angles of 45.degree. in radial directions, and these arms are joined to 
the lower parts of the section walls 22, 22 . . . or the above plate 
frames 24, 24, respectively. 
Moreover, each plate for preventing sinking 30 is horizontally projected at 
the lower inside of the above section walls 22, 22 . . . , at both lower 
sides of the plate frames 24, 24 . . . , around the lower part of the 
holder and at both lower sides of the above arms 29, 29 . . . . 
Then, as shown in FIG. 8 and FIG. 11, two joining projections 31, 31 are 
made on each of two adjacent sides which contain an angle and belong to 
four sides of the outer walls of the installing frame, respectively, and 
joining holes 32, 32 corresponding to the above joining projections 31, 31 
are constituted on the other two sides, respectively. The above joining 
projections 31, 31 on one side are constituted on the section wall 22 
(long side) or the section walls 22, 22 (short sides) of the above two 
square zones which are situated at the corners of the installing frame. 
Concerning the short sides of the holding section 21, these projections 
are naturally constituted on the section walls 22, 22 which are in common 
with the same outer wall of the installing frame. As shown in FIG. 9, FIG. 
10 and FIG. 12, the joining projections 31, 31 are projected from the 
outer walls of the installing frame so as to be situated slightly above 
the thickness of the protrusions 30, 30 . . . for preventing sinking. The 
projection width is about 4 mm, slightly widen than the thickness of the 
outer wall, namely 2 mm. The thickness of a height direction is about 6 
mm. Further, as shown in FIG. 8 and FIG. 11, the length of the direction 
along the outer walls of the above joining projections 31, 31 . . . is 
determined to be about 45 mm. The position of the direction is centered on 
the center point of the corresponding protrusion piece 23. 
Moreover, the above joining halls 32, 32 of the side of the outer wall of 
the installing frame corresponding to the above joining projections 31, 31 
are constituted on the other two sides, respectively. The above joining 
projections 31, 31 on the side are constituted on the section wall 22 
(long side) or the section walls 22, 22 (short sides) of the above square 
zones which are situated at the corners of the installing frame. As shown 
in FIG. 9, FIG. 10 and FIG. 12, the joining holes 32, 32 are made at the 
outer wall of the installing frame so as to be situated above the 
thickness of the protrusions 30, 30 . . . for preventing sinking. The 
height from the hole bottom of the joining holes 32, 32 is slightly above 
6 mm. Then, the length of the direction along the outer walls of the above 
joining holes 32, 32 . . . is slightly above the length of the 
corresponding direction of the above joining projections, namely slightly 
above 45 mm. 
Furthermore, the above whole constitution elements are integrally molded 
out of plastics which are obtained by mixing a main polypropylene 
material, and a weathering agent and the like. 
In this embodiment, as the installing frame is constituted as described 
above, the frame is used as described in the above first example and has 
the same action and effect except that the wooden bricks b-2, b-2 . . . 
having the plane rectangular configuration are held by the holding 
sections 21, 21 . . . . 
Moreover, in this embodiment, concerning the size of the installing frame, 
the wooden bricks b-2, b-2 which are formed in plane rectangular 
configuration having a short side of 100 mm, a long side of 320 mm and a 
height of 40 mm are suitable for the holding object. 
Before the installing frames are installed on sidewalks and the like, the 
wooden bricks b-2, b-2 are inserted and held in the holding sections 21, 
21, respectively. 
These steps, the action of each constitution element of the installing 
frame, and the like are the same as those of the first example. 
FIG. 11 shows that the plane rectangular wooden brick b-2 is held on each 
of the holding sections 21, 21, 21 of the installing frame in the same 
steps described in the first example. FIG. 13 shows that the wooden bricks 
b-2, b-2, b-2 which are placed on the holder 25, 25 . . . are fixed by 
screwing the vis 33, 33 inserted through the vis holes 7, 27 . . . . 
Further, in this example, as shown in FIG. 13, both of the plate frames 
24, 24. . . and the holders 25, 25, 25 act as pedestrias which place the 
wooden brick b-2. 
The instalating construction of sidewalks and the like begins by building a 
groundwork of gravel or concrete. 
The building of the above ground is conducted as described in the first 
example. 
The steps for installing the wooden bricks b-2, b-2 . . . to the ground 
after the bricks are held in the installing frame, and the action and 
effect are the same as those of the first example. 
Then, an example of the second invention is briefly explained. 
As shown in FIG. 14, an installing frame in which nine holding sections 41, 
41 . . . having plane round shapes are arranged in three perpendicular and 
three lateral lines is constituted in a frame 40. The above holding 
sections 41, 41 . . . are held in the frame 40 by the surrounding 
connection plates 55, 55 . . . . The frame 40 is constituted by the above 
connection plates 55, 55 . . . and the outer walls of outer edges, and the 
holding sections 41, 41 . . . are arranged in the frame as described 
above. 
The frame 40 of the installing frame, as described in the above two 
examples, is also constituted in a plane square having a side of 330 mm, 
the thickness of the outer wall is 2 mm, and the height is 40 mm. Further, 
the inside diameter of the above holding sections 41, 41 . . . is 106 mm, 
respectively. 
Each of the above holding sections 41, 41 . . . is surrounded by a section 
surrounding wall 42 having a ring shape. The thickness of the section 
surrounding walls 42, 42 . . . is 2 mm. Further, on the section 
surrounding wall 42 of the above holding sections 41, 41 . . . , as shown 
in FIG. 14, FIG. 15, FIG. 17 and FIG. 18, a protrusion piece 43 is 
protruded from the top into an oblique downward direction of the section, 
respectively. The width of the protruded direction of the above protrusion 
pieces 43, 43 . . . is 10 mm, and the angles between the protrusion pieces 
and the section surrounding walls 42, 42 . . . are about 30.degree.. As 
the result, the lower edge of the protrusion pieces 43, 43 . . . are 
protruded in the direction of the section center in about 5 mm. Further, 
as shown in FIG. 14, FIG. 15 and FIG. 17, eight notches 44, 44 . . . for 
penetrating water at regular angles of 45.degree. are formed in the above 
protrusion pieces 43, 43 . . . . 
At the lower center of each of the above holding sections 41, 41 . . . , as 
shown in FIG. 14, FIG. 15 and FIG. 18, a holder 45 of each wooden brick 
b-3 is arranged so as to stand up. The above holders 45, 45 are circular 
pedestals which stands up in a height of about 10 mm from the bottom of 
the holding sections 41, 41 . . . . Moreover, the upper surface of the 
holders 45, 45 . . . have round hollows 46, 46 . . . of which surrounding 
edges are left and the height is about 1 mm. A vis hole 47 is made at the 
center of each of the above round hollows 46, 46 . . . so as to pass 
through the upper surface and the under surface. Further, two small 
joining holes 48, 48 which are arranged on a straight line with the above 
vis hole 47 are made around the vis hole. As shown in FIG. 14, four arms 
49, 49 . . . are protruded from the surrounding of the above holder 45 at 
regular angles of 90.degree., and these arms are joined to the inside of 
the section surrounding wall 42 of the holding section 41. 
Moreover, a protrusion 50 for preventing sinking of the wooden bricks is 
horizontally projected around the lower part of the above holders 45, 45 . 
. . , at both lower sides of the above arms 49, 49 . . . and at the lower 
inside of the above section surrounding walls 42, 42 . . . , respectively. 
Then, as shown in FIG. 14, FIG. 16 and FIG. 17, many elastic tubes 56, 56 
for stepping and pressing are provided on connection plate 55 for 
connecting each of the holding sections 41, 41 to the above arrangement. 
The top of the tube 56, 56 . . . for stepping and pressing is determined 
so as to have almost same height as the top of the wooden bricks b-3, b-3 
. . . which are inserted and held in the holding sections 41, 41 . . . . 
In this example, the height of the tube 56, 56 . . . is 50 mm from the top 
to the bottom of the installing frame. 
On the contrary, as shown in FIG. 14, FIG. 15, FIG. 17 and FIG. 18, two 
joining projections 51, 51 are projected on each of two adjacent sides 
which contain an angle and belong to four sides of the outer walls of the 
above frame 40, respectively, and corresponding joining holes 52, 52 are 
made on the other two sides. The above joining projections 51, 51 on one 
side are formed on the outer wall which partly overlaps on the section 
surrounding walls 42, 42 of the holding sections 41, 41 situated at the 
corner of the frame 40. Then, as shown in FIG. 15 and FIG. 18, the joining 
projections 51, 51 are projected from the outer wall of the frame 40 so as 
to be situated slightly above the thickness of the protrusions 50, 50 . . 
. for preventing sinking. The projection width is about 4 mm, slightly 
wider than the thickness of the outer wall, namely 2 mm. The thickness in 
a height direction is about 6 mm. Further, as shown in FIG. 14 and FIG. 
17, the length of the direction along the outer walls of the above joining 
projections 51, 51 . . . is determined to be about 45 mm. 
Moreover, the above joining holes 52, 52 of the side of the outer wall of 
the frame 40 are arranged so as to correspond to the above joining 
projections 51, 51, and these holes are made on the outer wall which 
overlaps on the section walls 42, 42 of the holding sections 41, 41 
situated at the corner of the frame 40. As shown in FIG. 15 and FIG. 18, 
the joining holes 52, 52 are made at the outer wall of the frame 40 so as 
to be situated above the thickness of the protrusions 50, 50 for 
preventing sinking. The height from the lower part of the joining holes 
52, 52 is slightly above 6 mm. Then, the length of the direction along the 
outer walls of the above joining holes 52, 52 . . . is slightly above 45 
mm. 
Furthermore, the above whole constitution elements are integrally molded 
out of plastics which are obtained by mixing a main polypropylene 
material, and a weathering agent and the like. 
In this embodiment, as the installing frame is constituted as described 
above, as explained in the following, the frame can be used by holding for 
the pavement of sidewalks and the like, the wooden bricks b-3, b-3 . . . 
having the plane round configuration in the holding sections 41, 41 . . . 
. The plane round wooden bricks b-3, b-3 . . . having a diameter of 100 mm 
and a thickness of 40 mm are suitable for the holding object. 
Before the installing frames are installed on sidewalks and the like, the 
wooden bricks b-3, b-3 . . . are inserted and held in the holding sections 
41, 41 of the installing frames, respectively. The steps and the action 
and effect which are caused by each constitution element of the installing 
frame are the same as those of two examples of the first invention. 
Then, FIG. 17 shows the installing frame in which the wooden bricks b-3, 
b-3 . . . . FIG. 18 shows a condition in which the wooden bricks b-3, b-3 
. . . are inserted in the holding sections 41, 41 . . . and fixed on the 
holder 45, 45 . . . with the vis 53, 53 . . . . 
Further, the ground constitution of the necessary installing zone of 
sidewalks and the like is the same as that of two examples as described 
above. 
The steps for installing the frame which holds the wooden bricks b-3, b-3 
on the ground are also identical with those of the first example of the 
present invention. 
The actions and effects of the installing frame are almost identical with 
those of the above example of the present invention. 
Differences are as follows. 
In this example, as the tubes 56, 56 . . . for stepping and pressing are 
provided on the connection plates 55, 55 . . . between the holding 
sections 41, 41 . . . , pedestrians can walk and cars can run on the 
plates, and it is unnecessary especially to fill up the gaps which exist 
between the plane round holding sections 41, 41 . . . . Further, as the 
tubes 56, 56 . . . for stepping and pressing are passed through the 
plates, rainwater and the like can be allowed to flow on the ground. 
INDUSTRIAL APPLICABILITY
