The present invention does not use a binding material such as nails, bolt-nuts, adhesives, etc. when connecting two or more square sections of lumber or plate at one intersection to XY-axis right-angle connection, XYZ-axis connection, or diagonal connection to XYZ-axis intersection. The present invention relates to a multi-axis cross connection structure that can securely connect without a connection.

When connecting pillars and strips and longitudinals, or diagonals to columns and strips and longitudinals at one intersection, so far they have been nailed to the connection point, fastened with bolts and nuts or glued together. It has been recognized as a practice to fix it by means of application.

However, this old multi-axis cross connection structure is time-consuming and inconvenient for its connection work, and the cost is also large and unsuitable as a connection structure that can be reassembled after disassembly.

Accordingly, an object of the present invention is simple, when two or more members are connected so that the XY axis, the XYZ axis, and the XYZ-α axis intersect at one point, the connection part is simple without nailing, bolt-nut fastening, adhesive, or the like. It is robust, fast and easy for anyone to connect, and it is easy to disassemble and provide a multi-axis cross connection structure.

It is another object of the present invention to provide a multi-axis cross connection structure in which the connected traces are not apparent in appearance and look neat.

In the present invention, the connection structure varies depending on the number of multi-axis members connected at one point, for example, X-Y-axis, X-Y-Z-axis, and X-Y-Z-α-axis joint, but one common feature is one. In other words, while connecting grooves such as pillar, cross member, longitudinal member, and diagonal member are connected to each other, the member is connected to the pillar member by turning the member horizontally by 90 ° with the eccentric shaft as the axis of rotation in the member member member member. All of the connecting materials are firmly connected.

The basic ground of the present invention is assumed that the pillars and the cross members are square rods having the same standard cross section, and the pillar members have the following connection structure using the X axis and the cross member as the Y axis. That is, the column member has a connecting groove for supporting the eccentric shaft of the horizontal member, and the horizontal member has an eccentric shaft capable of pivoting at least 90 degrees using the connecting groove as a bearing. This eccentric shaft is formed as a circular round shaft which is slightly away from the end of the cross member and is located at its one corner.

In addition to the column or the horizontal member, the vertical member or the diagonal member may be connected together. In this case, the pillars are connected to the grooves for these additions, and the vertical and diagonal members also have a pillar and the horizontal or diagonal or longitudinal connection grooves. However, the cross member is not structurally different, but there is only a difference in that the length of the eccentric shaft is short and long. The vertical material added here is the Z axis, and the diagonal material is the α axis.

Hereinafter, embodiments of the present invention will be described in detail.

1 to 3 show a basic connection structure for connecting at right angles using two members. Likewise, the pillar member 10, which is a square or square bar of cross section, has a Y axis, and is a horizontal member. 20 is the X axis.

First, in FIG. 1, a cross member connecting groove 11 is formed near the upper end of the pillar member 10. The connecting groove 11 is J-shaped when viewed from the side, its front and rear width is limited to 1/2 of the overall width, the height of the connecting groove 11 is equal to the length of one side of the cross member 20, the valley ( 12 is formed in a semicircular arc shape having the front and rear widths as diameters. This is necessary in order to prevent the eccentric shaft 21 from coming out of the flaw when the cross member 20 is connected, and at the same time, to prevent the connecting marks between the column member 10 and the cross member 20 from shifting. . At the same time, one side of the upper end of the connection groove 11 extends straight to form a brace 13. This bracing portion 13 is an end portion outside the eccentric shaft 21 of the cross member 20 when the cross member 20 is inverted by 90 ° after sandwiching the eccentric shaft 21 of the cross member 20. The front surface 23 of the 22 is an element that is forced to the bottom surface of the brace 13 so as to be stuck.

The cross member 20 forms a round bar-like eccentric shaft 21 by cutting a position leaving one end slightly. The length s1 of this eccentric shaft 21 is equal to the length of one side of the pillar member 10 having a square cross section. In addition, it is placed in a place which is circumscribed simultaneously on both sides at one corner. The thickness is equal to the radius of the furnace 12.

Assembling the horizontal member 20 to the pillar member 10 of the structure as described above is the same as the second. The process is detailed in Figure 3. First, the eccentric shaft 21 is pressed into the cross member connecting groove 11 of the pillar member 10 by holding the cross member 20 so that the eccentric shaft 21 is placed on the back of the cross member 20. A) span the eccentric shaft 21 in the valley 12 (b). Subsequently, the horizontal member 20 is reversed 90 degrees toward the back of the column member 10 (C). Then, the eccentric shaft 21 is pressed down against the valley 12 by force, and the bottom 23 of the brace 13 is forced to endure the front surface 23 of the end 22.

As a result, the eccentric shaft 21 is trapped in the valleys 12 of the connection grooves 11 so as not to fall into any of the front and rear as well as the front and the rear of the connection grooves 11. Thus, the connection of the horizontal member 20 to the pillar member 10 is a strong edge connection state without nailing, bolt-nut, and adhesive.

Next, another embodiment of the present invention related to the fourth to sixth degrees will be described. This embodiment also shows a case in which the vertical axis 30 of the Z axis is connected to the pillar material 10 of the Y axis and the horizontal member 20 of the X axis at one corner.

The pillar material 10a has the horizontal member connecting groove 11a and the vertical member connecting groove 16 at the same time. However, in the pillar material 10 of the first embodiment, the valleys 12 at the lower end of the cross member connecting groove 11 are removed and the brace part 13 extending from the contact flaw 11 is omitted, and the c-phase One point is different in cross section. The longitudinal member connecting groove 15 has half the width of the member connecting groove 33. Thus, while forming the eccentric shaft 31 of the longitudinal member 30 in a square cross section, the width | variety of the cross member connecting groove 11a is the same, and height is about 1/2 small compared with the cross member connecting groove 11a.

However, the cross member 20 is not different from the first embodiment. Newly added new material 30 also has an eccentric shaft 31. However, the eccentric shaft 31 is slightly different from the eccentric shaft 21 of the longitudinal member 30 as a square rod while the eccentric shaft 21 of the cross member 20 is a round rod. ) Is the same as the longitudinal width of the column member (10a) and one side of the cross member 20, but the column connecting groove 32 is a differential in the length of the cross member connecting groove 33 and the pillar connecting groove (32). The vertical width of the vertical contact groove 15 of the column member 10a and the vertical contact groove 15 of the column member 10a correspond to only half the width of the longitudinal member connection groove 15 of the pillar member 10a. It is to let.

When the pillar material 10a, the horizontal material 20, and the vertical material 30 are completely assembled, it becomes like FIG. 5b. On the contrary, referring to FIG. 6, first, the eccentric shaft 21 of the cross member 20 is placed in the cross member connecting groove 11 a of the column member 10 a and inserted into the end. Subsequently, the eccentric shaft 31 of the longitudinal member 30 is also fitted to the longitudinal member connecting groove 15 in a state where it is placed on the outer upper portion of the longitudinal member 30. At this time, the inner surface of both ends of the eccentric shaft 21 is placed in a state coinciding with the boundary line of both ends of the eccentric shaft 31 of the longitudinal member 30, thereby reversing the horizontal member 20 (a).

Then, the horizontal member 20 is reversed 90 degrees toward the rear of the column member 10a (b). Then, the column member 10a and the vertical member 30 are trapped by the horizontal member 20 and at the same time, the horizontal member 20 is also bound to the column member 10a by the vertical member 30. As a result, the column member 10a, the horizontal member 20, and the vertical member 30 are entangled with each other and are firmly connected to each other.

This time, another embodiment of the present invention, that is, when the column member 10b is connected to the Y axis, the horizontal member 20 is the X axis, and the vertical member 30a is the Z axis, and is connected at one corner, the column member ( The connection structure in the case where the diagonal member 40 is inclined at an angle with respect to 10b) and the cross member 20 at a time will be described. The contents of this modified embodiment are well illustrated in FIGS. 7 to 9.

First, referring to FIG. 7, the column member 10b is provided with a cross member connecting groove 11 and a diagonal member connecting groove 17. The strip member connecting groove 11 is J-shaped when viewed from the side as in the first embodiment, but its width is only one third of it. The other two-thirds are occupied by the diagonal grooves 16. This diagonal member connecting groove 16 is literally a groove cut in the comb direction, and occupies a place where the vertical member connecting groove 15 in the second embodiment is formed, and the center thereof is a horizontal member connecting groove ( It is equal to the cross-sectional center of the cross member 20 connected to 11), and its height is also equal to the length of one side of the diagonal member 40.

Here, the cross member 20 is not structurally changed. However, the vertical material 30a has many changes. For example, in the second embodiment, where the column connecting groove 32 of the eccentric shaft 31 was located, the upper connecting groove 34a for the diagonal member and the lower connecting groove 34b for the diagonal member are vertically combed. It is replaced by forming to be on line. That is, the pillar connecting groove is excluded. The connecting grooves 34a and b and the cross member connecting grooves 32 on the diagonal have the same size as the right angled cross section of the diagonal member 40 and the cross member 20.

Moreover, in the diagonal member 40, between the column member connecting groove 41 and the longitudinal member connecting groove 43 is 1/3 of the thickness thereof. Therefore, the width of the diagonal member connecting grooves 34a and b on the longitudinal member 30a becomes 2/3 of the length of the horizontal side. Therefore, when the diagonal member 40 is connected to the column member 10b and the vertical member 30a is connected again, the connection thickness is equal to the thickness of one of the pillar member 10b, so that the surface of the other member is not blown out either way. Looks smooth.

In addition, the diagonal member 40 has both the column member connecting groove 41, the horizontal member connecting groove 42 and the longitudinal member connecting groove 43. The pillar connecting groove 41 corresponds to one third of the total width, and the horizontal connecting groove 42 is the same as the horizontal connecting groove 11 of the pillar 10b when viewed from the side, and the vertical connecting groove Reference numeral 43 crosses the pillar material 10b at a right angle, and the size is the same as that of the cross section of the eccentric shaft 31.

FIG. 8a shows a state in which the diagonal member 40 and the cross member 20 are preliminarily connected to the column member 10b in sequence, and FIG. 8b shows a subsequent assembly of the longitudinal member 30a, and FIG. In Figure, the horizontal member 20 inverted by 90 ° in the same manner as described above shows the state of completing the connection.

In this case, as shown in Fig. 9, first, the column connecting groove 41 of the diagonal member 40 is fitted into the diagonal member connecting groove 16 of the pillar member 10b. At this time, since the rear surface of the pillar connecting groove 41 is in contact with the back surface of the pillar material 10b, the connected diagonal member 40 does not slide down even though the diagonal member connecting groove 16 is deviated. Moreover, each of the cross member connecting grooves 11 and 42 is aligned in a J shape. In this state in which the diagonal member 40 is stabilized, this time the eccentric shaft 21 of the member 20 in the member connecting grooves (11, 42) through the open side of the front jaw (14, 44) prior embodiment Push in the same way and descend to span the goal (12, 45). Then, the eccentric shaft 21 of the cross member 20 is in a situation in which the cross member connecting grooves 11 and 42 are trapped in the valleys 12 and 45 and cannot fall back and forth, but artificially, the front jaw ( (A) It can be lifted into the open space on 14 (44).

In the (A) state, insert the longitudinal material (30a) this time. At this time, the eccentric shaft 31 of the longitudinal member 30a extends in the longitudinal direction to the longitudinal member connecting groove 43 of the diagonal member 40, and at the same time, the lower connecting groove 34b is the horizontal member of the diagonal member 40 side. The front grooves 44 and 14 of the connection groove 42 and the pillar material 10b are completely covered. Then, the pillar material 10b, the diagonal material 40, and the vertical material 30a are all preliminarily connected to fall within the range of the eccentric shaft 21 on the horizontal material 20 side (b).

After the preliminary connection is made, the horizontal member 20 is inverted by 90 ° in the same manner as in the above embodiments. Inverted about the eccentric shaft 21, the front surface 23 is changed to the upper surface, the inner surface of the outer end 22 is caught by the outer surface of the pillar 10b and the inner surface of the inner end 22a is vertical ( It is caught by the outer side of 30a) and the outer side of diagonal material 40. In this way, when the column member 10b, the longitudinal member 30a, and the diagonal member 40 are surrounded by the member 20, any member cannot escape the binding state without artificial manipulation (c). Each of the above embodiments is applicable to a skeleton of a wooden building, a skeleton of a merchandise display stand, and the like.

10 to 12 show a case in which the pillar member 10a, the barrier member 20 and the longitudinal member 30 of the second embodiment are replaced by a board, where the barrier member 20a corresponds to the side wall. There is a feature in that it functions only for connection between the column member 10a and the longitudinal member 30 forming the upper plate. When the column member 10a, the cross member 20a, and the longitudinal member 30 are completely assembled, they are as shown in Figs. 11 and 12, and the details thereof are the same as the assembly procedure of the second embodiment (Fig. 6). It is a connection structure and method suitable for a bookshelf, a display stand, and the like.

In the case of continuous construction in the horizontal, vertical, or height directions based on a cube lattice or a cube lattice, each member may be used subsequently. 13 to 15 show a connection structure suitable for the case where the joints 10c and the longitudinal member 30b exist at one corner of the column member 10c, the horizontal member 20 and the longitudinal member 30b. It is shown.

The one end 10c and the longitudinal material 30b arrange an end part in the shape, and the other end 10c and the longitudinal material 30b end up in the shape here. Thus, the connecting elements such as, for example, pins 17a-pinholes 17b, 36a and 36b are attached to each other in the end of each direction in which the edges are arranged, and then connected with each other, as in the case of the second embodiment. The XYZ axis connection is performed by the following method. This joint structure is applicable not only to X-Y-Z-axis connection but also to X-Y-axis connection and X-Y-Z-α-axis connection.

Finally, FIG. 16 illustrates an example of utilization of each of the above connection structures and methods.
