in the embodiment illustrated in fig1 through fig6 the ornamental flower bed base assembly or matrix material 1 according to this invention comprises a base plate 2 and a plurality of flower plant holders 3 which can be removably mounted on said base plate 2 . the base plate 2 is part of a hollow base frame 4 forming a semi - spherical curved surface and a plurality of circular mounting openings or insertion through - holes 5 disposed at uniform intervals over the entire surface of said hollow base frame 4 . this base plate 2 is made of plastics or light metal so that it will not contribute much to the overall weight . the flower plant holders 3 are also made of lightweight plastics and , in this particular embodiment , each consists of a top ring - shaped flange frame 6 , a ring - shaped bottom frame 7 and a plurality of longitudinal frame members 8 interconnecting said top and bottom frames and forming a lateral side of the flower plant holder 3 . therefore , this flower plant holder is open not only at the top but has ample irrigation openings or orifices 9 along the lateral and bottom sides . moreover , this flower plant holder 3 has a flower plant anti - slip member 10 adapted to prevent accidental slip - off of the flower plants . the anti - slip member 10 , in this embodiment , comprises a top ring - shaped , inwardly - oriented flange 11 , a plurality of legs 12 projecting downwards from said flange 11 with some outwardly biasing resilient force , and an engaging projection 14 having upper and lower tapered guide faces 13 . when this flower plant antislip member 10 is inserted into the holder 3 , said projection 14 is engageable with the lower edge of the flange frame 6 of the holder 3 . the overall configuration of the holder 3 is preferably a tapered shape like the usual flower pot , for the mounting thereof into the insertion throughhole 5 can then be carried out smoothly . moreover , the outer diameter of the top portion of the holder 3 is preferably made slightly larger than the inner diameter of the insertion through - hole 5 , for the holder is then fit tight into the hole 5 so that it will not easily move off . to set the holder 3 securely in the insertion through - hole 5 , one may insert the holder 3 into the hole 5 and cause the projection 14 of the flower plant anti - slip member 10 to engage the lower circumferential edge of the insertion hole 5 . the holder 3 can be easily dislodged from the insertion through - hole 5 by pulling the holder 3 in the outward direction . as an alternative mounting method , though not shown , it may be so arranged that an engaging projection having upper and lower guide faces is provided externally of the longitudinal frame 8 of the holder so that when the holder is removably inserted into the insertion throughhole , said projection engages the inner portion of the peripheral edge of the through - hole . many other mounting modes may be used without departing from the scope of this invention . the following is a description of an exemplary procedure for planting flower plants in the flower plant holder 3 constructed as above . in order to prevent spilling of soil a from the holder , a material b having both water - penetrability and water - holding properties such as sphagnum ( moss ), polyurethane from sponge , rock wool or the like is first set in position and , then , soil a is poured into the holder . flower plants c are then planted in the soil and an additional amount of said material b is laid over the roots of the plants . by so doing , the soil a is precluded from being scattered away or the irrigation water from oozing out from the irrigation orifices . when grown in this condition for a certain time , the flower plants c grow and develop in the holder 3 and the flower plants are positively protected by the anti - slip members of the holder against slip - off so that even if the holder is inclined on its side or inverted , the flower plants will not slip off from the holder . fig7 and 8 show another embodiment of the flower plant holder according to this invention . this flower plant holder 3 , too , is made of lightweight plastics and is provided with a plurality of slit - like irrigation openings or orifices 15 , moreover , in a plurality of positions on the upper part of the peripheral wall of the holder 3 , a couple of engaging projections 17 , 17 having upper and lower tapered mounting guide faces 16 , respectively , are provided in two vertical rows at suitable intervals . in addition , at appropriate intervals on the top peripheral part of the flower plant holder 3 , a plurality of flanges 19 each having an engaging hole 18 are provided . moreover , this flower plant holder 3 is provided with an anti - slip means 20 adapted to prevent accidental slip - off of the flower plants from the holder 3 . this anti - slip member 20 is also molded from lightweight plastics and consists of a ring - shaped anti - slip body , the diameter of which is smaller than the inner diameter of the top opening of holder 3 and a plurality of engaging members 22 adapted to be inserted into the respective engaging holes 18 of the holder 3 , each of said engaging members extending downwardly from the outer periphery of said body 21 . as shown in fig7 this engaging member 22 has an engaging land 23 disposed on the outer side of each of its two legs and as these two legs of each engaging member 22 are forced into the corresponding engaging hole 18 , the engaging lands 23 are engaged by the lower edge of the flange 19 so as to mount the anti - slip member 20 on the top of the flower plant holder 3 . moreover , by closing the two legs of each engaging member 20 by inward biasing , the anti - slip member 20 can be separated from the flower plant holder 3 . moreover , the ring - shaped body 21 of this anti - slip member 20 is discontinuous in one position so that even if there is a minor error in the relative position of each engaging hole 18 and engaging member 22 , this discontinuation 24 assures smooth engagement and disengagement between the two elements . as shown in fig8 the flower plant holder 3 having the above construction can be positively mounted in the insertion through - hole 5 by inserting the holder 3 into the hole 5 and , then , engaging the peripheral edge of the insertion through - hole 5 between the engaging projections 17 in the upper row , among the projections 17 , 17 provided in two vertical rows , and a reinforcing rib 19a of each flange 19 . the holder 3 may be easily dismounted from the insertion throughhole 5 by pulling it outwardly . the engaging projections 17 in the lower row are provided as a secondary means for preventing disengagement of the holder 3 from the insertion through - hole 5 when the engaging projections 17 in the upper row are accidentally disengaged from the insertion through - hole 5 . then , a variety of modes can be employed for assembling such flower plant holders 3 carrying flower plants with the base plate 2 to construct an ornamental flower bed . to construct a spherical ornamental flower bed f as illustrated in fig9 for instance , two base plates 2 each part of a hollow spherically curved base frame 4 may be jointed by mating their open ends with each other and mounting a plurality of holders 3 carrying flower plants c into the respective insertion through - holes 5 of the base plate 2 . and the spherical ornamental flower bed f can for example be used as suspended from both ends of the horizontal beam e of a pole d as illustrated in fig9 . in this arrangement , the attractiveness of the flower balls as an ornamental flower bed is further enhanced . when it is desired to construct a wall type ornamental flower bed f such as the one shown in fig1 , a rectangular hollow base plate having a flat surface ( not shown ) may be provided with a multiplicity of circular or rectangular insertion through - holes at equal intervals over its entire surface and a flower plant holder 3 carrying flower plants be inserted into each of the through - holes . the resulting product is a flower wall type ornamental flower bed f . the above description pertains only to some preferred embodiments of this invention and these embodiments are only illustrative of the invention and by no means limitative of the scope of the invention . thus , many changes and modifications may be made in the shape , construction , relative position , etc . of said base plate 2 , insersion through - holes 5 , flower plant holders 3 , irrigation orifices 9 , 15 , anti - slip members 10 , 20 , engaging projections 14 , 17 and so on without departing from the scope of this invention .
an ornamental flower bed base assembly or matrix material comprising a flower bed base plate having a plurality of insertion through - holes disposed at appropriate intervals and a plurality of flower plant holders each having a side wall provided with irrigation orifices and an open top end , each of the flower plant holders being removably engageable with the respective insertion through - holes of the base plate . this matrix is lightweight and can be easily transported to the contemplated site of erection . using this ornamental flower bed matrix material , a variety of ornamental flower beds can be constructed easily at site . the resulting flower beds are attractive and easy in maintenance .
