detailed description

Hereinafter, the present invention will be described in further detail based on the embodiments shown in the drawings. FIG. 1 is a diagram showing the overall structure of a movable rack 11 as a prefabricated block structure 10 according to the present embodiment. FIG. 2 is a perspective view showing the overall structure of a prefabricated shelf 12 as the prefabricated block structure 10 of the present embodiment. Each prefabricated block structure 10 is configured to include a support frame 13 and a lateral frame 14 .

The support frame 13 is constituted by combining a plurality of support blocks 20 . In the example shown in FIGS. 1 and 2 , a plurality of support blocks 20 are stacked up and down to form one support frame 13 .

As shown in FIG. 3 , the support block 20 is formed of a synthetic resin molded product, and has a pillar portion 21 , a partition wall portion 22 , a supporting notch 23 , and a receiving notch 26 . A plurality of pillar portions 21 are provided at predetermined intervals along the longitudinal direction of the support block 20 . Each pillar part 21 is formed in a cross-sectional substantially square shape with a height of about several centimeters to several tens of centimeters. Of course, the cross-sectional shape and the like are arbitrary, and may be approximately circular. The part 21a is formed in a substantially square cross section, and the pillar part 21b located at the other end is formed in a substantially semi-elliptical cross section. However, in order to increase the strength, it is preferable to form the side surface 21c constituting each pillar portion 21 so as to be located as close to the lower end edge as possible.

The partition wall portion 22 is provided so as to straddle between the pillar portions 21 , 21 adjacent to each other along the longitudinal direction in the vicinity of the substantially center in the height direction of the support block 20 . As a result, two cutouts (the support cutout 23 and the accommodation cutout 26 ) are formed between the adjacent pillar parts 21 , 21 at the upper and lower sides sandwiching the partition wall part 22 .

The support notch 23 is a notch opened on the upper part of the partition wall 22, and is formed in a size for accommodating an end 41 of a rod-shaped member 40 described later. An engaging portion that engages with an engaged portion formed at an end portion 41 of the rod-shaped member 40 described later is formed on the inner surface of the support notch portion 23 . As will be described later in detail, the engaged portion is the tenon portion 42 provided at the end portion 41 of the rod-shaped member 40 . The engaging portion is a dovetail groove 24 formed so as to allow insertion of the tenon portion 42 .

Moreover, in this embodiment, the connection wall 25 which connects the intermediate part in the thickness direction of each support|pillar part 21 is provided, and the notch part 23 for support is formed in both sides which pinches|interposes the said connection wall 25. Therefore, in this embodiment, the insertion length of the end portion 41 of the rod-shaped member 40 into each supporting notch portion 23 is approximately half of the thickness obtained by subtracting the thickness of the connecting wall 25 from the thickness of the pillar portion 21. length.

The accommodating notch 26 is a notch formed in the lower portion of the partition wall 22 and opened on the lower surface, and is formed by an area into which an end 41 of a rod-shaped member 40 described later can be inserted when viewed from the front.

The support frame 13 is formed by vertically connecting a plurality of support blocks 20 . Therefore, the upper part and the lower part of each pillar part 21 of the support block 20 are formed so that the lower part and the upper part of each pillar part 21 of the other support block 20 arrange|positioned vertically can respectively be fitted. In other words, the outer diameter of the upper portion of the pillar portion 21 is smaller than the inner diameter of the lower portion. Therefore, when the support blocks 20 are vertically connected, the upper portion of the support block 20 disposed on the lower side fits into the peripheral wall of the lower portion of the support block 20 disposed on the upper side.

In order to suppress the fall of the support block 20 arranged on the upper side, at least one of the pillar parts 21, in this embodiment, the pillar part 21a located at one end in the longitudinal direction is formed to extend upward. The projection part 27a of the support block 20 is inserted into the hole part 33a for projection arrange|positioned in the peripheral wall of the pillar part 21a of the support block 20 on an upper side. In addition, on the pillar portion 21b located at the other end in the longitudinal direction, the protrusion portion 27b formed to extend upward is inserted into the protrusion hole portion 33b arranged in the peripheral wall of the pillar portion 21b of the support block 20 on the upper side. middle. It should be noted that, among the support blocks 20 arranged at the upper end of the support frame 13, the support block arranged at the uppermost part (the support block with reference numeral 20A shown in FIG. As shown in Fig. 1, it is preferable to use a support block in which the protrusions 27a, 27b are not formed.

Here, in order to clarify the difference in the appearance structure of the support block 20 provided with the protrusions 27a, 27b, and the support block 20A arranged at the uppermost part without the protrusions 27a, 27b, the differences in the appearance structure of the support block 20A provided at the uppermost part are clarified in Figs. In (i), the whole structure of the former support block 20 is shown concretely as a reference, and the whole structure of the latter support block 20A is shown concretely as a reference in FIGS. 13(a)-(h).

The protruding portion 27a is formed in a hollow substantially quadrangular cross-section, and claw portions 28a, 28b are provided on the peripheral wall surface. In this embodiment, the claw parts 28a, 28b are arrange|positioned at the position which substantially opposes on the front side and the back side of the protrusion part 27a.

As shown in FIG. 3 and FIG. 4 , an inverted U-shaped notch is formed in a part of the peripheral wall, and inner pieces of the inverted U-shaped notch serve as spring pieces 29a and 29b for claws having elasticity. The lower parts of the spring pieces 29a and 29b for claws are integrated with the peripheral wall of the protrusion 27a, and the upper parts have elasticity to bend inwardly and outwardly. The said claw parts 28a, 28b are provided in the outer side of the upper end part of spring piece 29a, 29b for claw parts. Therefore, when the claws 28a, 28b are pressed inward, an elastic force that biases the claws 28a, 28b outward is generated by the claw springs 29a, 29b.

In this embodiment, the claws 28a, 28b protrude outward from the peripheral wall surface of the protrusion 27a, and slopes 31a, 31b are formed on the outer surfaces of the claws 28a, 28b. The portion 27a is inclined such that the bottom of the portion 27a protrudes gradually downward, opposite to the direction in which the protrusion hole portion 33a is inserted.

On the other hand, the protrusion hole portion 33a arranged in the peripheral wall of the pillar portion 21a of the support block 20 on the upper side is provided with locking hole portions 34a, 34b provided with the claw portion 28a. , 28b to engage the claw housing portion 35a, 35b. In other words, the lower semicircular portions of the locking hole portions 34a, 34b serve as the claw accommodating portions 35a, 35b. In the present embodiment, the locking holes 34 a and 34 b are arranged at positions substantially facing each other on the front side and the back side of the protrusion hole 33 a.

Therefore, when the support blocks 20 are connected up and down, the protrusions 27a, 27b of the support blocks 21a, 21b of the lower support block 20 are inserted into the corresponding protrusion hole portions of the support blocks 21a, 21b of the upper support block 20. 33a, 33b. Since the structure of the pillar part 21a, 21b is substantially the same, it demonstrates in detail about the pillar part 21a.

As shown in FIG. 4( a ), the claws 28a, 28b of the protrusion 27a of the lower support block 20 protrude outward from the position of the inner periphery of the protrusion hole 33a of the upper support block 20 . When inserted, as shown in Fig. 4 (b), (c), the end edge of the protrusion hole 33a overcomes the elastic force of the claw springs 29a, 29b and the inclined portion of the claw 28a, 28b of the protrusion 27a 31a, 31b are pressed inward. When further inserted, as shown in FIG. 4( d), the claws 28a, 28b of the projection 27a are locked to the corresponding projection hole 33a by the outward force of the claw springs 29a, 29b. The hole portions 34a, 34b are inserted and engaged with the claw accommodating portions 35a, 35b.

It should be noted that the protruding portion 27b has the same structure as the above-described protruding portion 27a, so detailed description thereof will be omitted. In other words, the spring pieces 29a, 29b for claws provided with the claws 28a, 28b are included. In addition, since the protrusion hole 33b disposed in the peripheral wall of the pillar portion 21b of the upper support block 20 has the same structure as the protrusion hole 33a described above, detailed description thereof will be omitted. In other words, locking hole portions 34a, 34b provided with claw accommodating portions 35a, 35b are included.

Therefore, when the support block 20 is vertically connected, the claw portions 28a, 28b of the protrusion portion 27a engage with the claw accommodating portions 35a, 35b of the locking hole portions 34a, 34b of the corresponding protrusion hole portion 33a. In addition, the claw portions 28a, 28b of the projection portion 27b are also engaged with the claw receiving portions 35a, 35b of the locking hole portions 34a, 34b of the corresponding projection hole portion 33b. As a result, the degree of connection between the upper and lower support blocks 20 can be further increased, so that the function of suppressing the fall of the support blocks 20 is improved.

In the form shown in FIGS. 1 and 3 , the protrusion hole 33 a in the peripheral wall of the pillar portion 21 a at one end in the longitudinal direction of the support block 20 at the lowermost part of the support frame 13 and the pillar at the other end The caster 50 is attached to the hole part 33b for protrusions in the peripheral wall of the part 21b. As shown in FIG.5(a), (b), the said caster 50 is equipped with the protrusion part 51 for attachment which can be inserted into either of the hole part 33a, 33b for protrusions.

As shown in FIG. 5( a ), in the protruding hole 33 a having a substantially square cross-section of the pillar portion 21 a of the lowermost support block 20 , there is an edge protruding from the peripheral wall surface on the side of the adjacent pillar portion 21 . The two rail portions 36, 36 are long in the vertical direction. Moreover, in the said hole part 33a for protrusions, two rail parts 37 and 37 protrude from the peripheral wall surface facing the peripheral wall surface of the two rail parts 36 and 36. As shown in FIG. On the other hand, in the protrusion hole 33b having a substantially semi-elliptical cross-section of the pillar portion 21b, the same protrusion as the protrusion hole 33a protrudes from the peripheral wall surface on the side of the adjacent pillar portion 21. The two rail portions 36, 36 are long in the vertical direction.

The mounting protrusion 51 of the caster 50 is formed in a substantially semi-elliptical cross-section that can be inserted into the protrusion hole 33b of the substantially semi-elliptical cross-section of the pillar portion 21b, and a flat surface for The two guide groove portions 52 , 52 guide the two guide rail portions 36 , 36 . In addition, two guide groove portions 53 , 53 for guiding the two guide rail portions 37 , 37 are formed on the substantially semi-elliptical peripheral surface.

It should be noted that the mounting protrusion 51 of the caster 50 is formed of a hollow cross-sectional substantially quadrangular shape, and the claw springs provided with the claws 28a, 28b are provided on the peripheral wall surface similarly to the above-mentioned protrusions 27a, 27b. Sheets 29a, 29b.

In this embodiment, the claws 28a, 28b of the protrusion 27a, the claws 28a, 28b of the protrusion 27b, and the claws 28a, 28b of the attachment protrusion 51 have the same positional relationship and the same size. In addition, the claw accommodating portions 35a, 35b of the protrusion hole portion 33a in the peripheral wall of the pillar portion 21a, and the claw accommodating portions 35a, 35b of the protrusion hole portion 33b in the peripheral wall of the pillar portion 21b have the same positional relationship and the same size. Therefore, the caster 50 can be easily attached to any one of the hole part 33a for protrusions of the support|pillar part 21a, and the hole part 33b for protrusions of the support part 21b. The method of its assembly is the same as that of the pillar part 21a shown in Fig. 4 (a) to (d).

The lateral frame 14 is formed of a plurality of bar-shaped members 40 . As shown in FIG. 6 , the rod-shaped member 40 has tenon portions 42 , 42 provided in the vertical direction on the side surfaces of the respective end portions 41 , 41 . The tenon portion 42 functions as an engaged portion that engages with the dovetail groove 24 , which is an engaging portion provided in the support notch portion 23 . The dovetail groove 24 and tenon portion 42 increase the strength of the engaging portion of the supporting notch portion 23 and the end portion 41 of the bar member 40 compared to simple engaging pieces and groove portions, thereby improving the strength of the lateral frame.

In addition, the end portion 41 of each rod-shaped member 40 is formed with a cross-sectional area smaller than that of each receiving notch portion 26 viewed from the front. However, as long as the cross-sectional area of the end portion 41 engaged with the supporting notch portion 23 satisfies such conditions, the cross-sectional area (or outer diameter) of the portion other than the end portion 41 may be larger than that of the receiving notch portion 26 .

When each rod-shaped member 40 is formed of thinned materials such as cedar and cypress, it is preferable to effectively utilize the thinned materials, but the material of the rod-shaped members 40 is not limited to the thinned materials. Other woods (including end materials in wood processing, etc.), synthetic resins, metal pipes, etc. can also be used. However, from the viewpoint of weight reduction, effective use of resources, and cost, it is preferable to use thinned materials as described above.

In this embodiment, the support blocks 20 are connected vertically. At this time, the protrusions 27a, 27b of the lower support block 20 are inserted into the protrusion holes 33a, 33b of the support blocks 21a, 21b at both ends of the upper support block 20 as described above. Then, as shown in FIGS. 4(a) to (d), in the pillar portion 21a, the claw portions 28a, 28b of the projection portion 27a are inserted toward the locking hole portions 34a, 34b of the corresponding projection hole portion 33a to engage with the claws. The accommodating parts 35a and 35b are engaged and locked easily. Also in the pillar part 21b, it is simply locked similarly to the pillar part 21a.

As mentioned above, using the support block 20 of a simple structure, the support frame 13 of predetermined height is formed without using a screw, a nut, etc. In addition, the support notch 23 of the support block 20 disposed on the lower side communicates with the accommodation notch 26 of the support block 20 disposed on the upper side vertically, forming one hole as shown in FIGS. 1 and 2 .

Next, two support frames 13 having a predetermined height are arranged to face each other, and the rod-shaped member 40 is supported between the two support frames 13 , 13 . In the support frame 13 , among the support blocks 20 stacked vertically, the support notches 23 and the accommodation notches 26 communicate vertically as described above. In this regard, first, the end portion 41 of the rod-shaped member 40 is inserted into the receiving notch portion 26 of the support block 20 arranged on the upper side. At this time, since the area of the notch 26 for accommodation viewed from the front is larger than the cross-sectional area of the end 41 of the rod-shaped member 40, insertion can be facilitated. Then, after inserting the two ends 41,41 of the rod-shaped member 40 into the opposing receiving notches 26,26, press down directly so that the tongues 42,42 of each end 41,41 are respectively aligned with the supporting notches. The dovetail grooves 24, 24 of the parts 23, 23 are engaged. Thereby, the end part 41 of the rod-shaped member 40 can be reliably supported by the support notch part 23, without using a screw, a nut, etc. When a desired number of rod-shaped members 40 are arranged in the depth direction, the horizontal frame 14 having a predetermined width is formed.

As above, the area of the receiving notch 26 viewed from the front is larger than the cross-sectional area of the end 41 of the rod-shaped member 40, so even if several other rod-shaped members are disposed between the two supporting frames 13, 13 40, that is, when the opposing distance between the two support frames 13, 13 is fixed, the rod-shaped member 40 can be inserted into any supporting notch 23 or the inserted rod-shaped member can be taken out. Therefore, the degree of freedom of arrangement and disassembly of the rod-shaped members 40 forming the lateral frame 14 is extremely high, and the prefabricated block structure 10 of the size and shape desired by the user can be obtained. In addition, the height of the support frame 13 can also be set to an arbitrary height by the number of connections of the support blocks 20 .

Therefore, for example, it can be used as a low movable stand 11 as shown in FIG. 1 , or it can be used as a bookshelf as shown in FIG. 2 when it is set higher, and the degree of freedom of use is extremely high. In addition, it can be used as a TV table, a cargo rack, a chair, a shelf part of a bed, etc. In addition, since the minimum unit of parts is the support block 20 or the rod-shaped member 40, when disassembled into these parts, it can be extremely compacted, so it is convenient to carry and store.

In addition, it is preferable to prepare in advance multiple types of support blocks having different lengths in the longitudinal direction as the support blocks 20 , or to prepare in advance multiple types of rod-shaped members with different lengths as the rod-shaped member 40 . For example, as shown in FIG. 2, by using rod-shaped members 40 with different lengths, the width of the prefabricated block structure 10 (the distance between the support frames 13 and 13) can be varied depending on the location, and the prefabricated block can be further expanded. Use of Construct 10. In addition, various adjustments can be made to suit the size of the room to be installed.

Next, a lock release tool according to an embodiment of the present invention will be described.
