Description

The present invention relates to a member connection structure for detachably connecting paired members to be connected to each other.

As a structure for detachably connecting a pair of connection target members, in addition to a structure in which the connection target members are screwed together, a magnet type structure for connecting both connection target members using the magnetic force of a magnet, or one of them. A mechanical type or the like is known in which a convex portion provided on a connection target member of No. 1 and a concave portion provided on the other connection target member are engaged with each other in a concavo-convex manner to detachably connect both connection target members (for example, a patent). See Document 1).

However, since the magnet type is connected by magnetic force, the connection force is relatively weak, and if such a member connection structure is adopted when constructing a large structure, there is a risk that the whole will be deformed or collapsed. Must be worried. In order to reduce such anxiety, a strong magnet may be used, but if the members to be connected are connected to each other with a magnet that is too strong, a large force is required when disassembling the members, which adversely affects workability.

On the other hand, in the mechanical type, since the convex portion and the concave portion are physically engaged and disengaged, a relatively reliable connection can be realized in the engaged state, but the convex portion and the concave portion are engaged while being aligned. Not only is it difficult to assemble because it is necessary, but also the members to be connected to be finally connected are relatively moved to engage the convex portion with the concave portion, so that the assembly order is easily restricted.

It is possible to transmit to the interlocking bar R1 via. That is, as shown in FIGS. 13 to 16 and 19, the lock operation portion R4 is a bolt-shaped one having an operation reception portion R41a at the outer end of the operation body R41, and is a core portion 50 of the vertical frame 5. It is rotatably attached to the vertical frame 5 in a state where it is integrally rotatably pierced by the pinion R42 housed inside. A window hole 51b for exposing the pinion R42 to the groove 5a is formed in a portion of the bottom wall 51 of the vertical frame 5 corresponding to the pinion R42, and the exposed portion of the pinion R42 is provided on the connecting bar R1. It is engaged with the rack R43. In this rack R43, a plurality of rectangular through holes R43a that engage with the teeth R42a of the pinion R42 are formed on the connecting bar R1 at a predetermined pitch. R44 is a detent to prevent the pinion R42 and the operating body R41 from slipping.

As shown in FIGS. 13 to 16 and 19, the lock pin R2 is projected from a portion corresponding to each engagement hole R1a in the vertical frame 4, and has a large diameter portion R21 at the tip thereof. The lock pin R2 is attached to the bottom wall 41 of the vertical frame 4.

Has been done.

The interlocking bar R1 of the mechanical lock mechanism R described above is made of a magnetic material that can be attracted to a magnet, and the interlocking bar R1 can be held at the lock position (p) by the auxiliary magnet R3. That is, in the state where the interlocking bar R1 is raised to the lock position (p), the upper end portion R1c of the interlocking bar R1 is attracted to and held by the auxiliary magnet R3.

Here, the operation of the member connection structure described above will be described.

First, while keeping the right vertical frame 5 (one connection target member) of the first peripheral wall panel 1A and the left vertical frame 4 (the other connection target member) of the second peripheral wall panel at substantially the same height level. As they are brought closer to each other, as shown in FIGS. 11 and 12, both vertical frames 5 and 4 are magnetically attracted to each other by magnetism by the magnetic temporary fixing mechanism M, and are temporarily connected to each other. At that time, even if the height levels of the two vertical frames 5 and 4 are slightly different, the tip portion M2a of the magnetic unit M2 (the tip portion M2a of the magnet holder M22) has a side view table shape. The vertical relative positions of the vertical frames 5 and 4 are corrected when they are fitted to the magnet receiver M1 that forms a shape, and when the magnetic unit M2 is finally attracted to the magnet receiver M1, both vertical frames 5 and 4 are attached to each other. The vertical positioning of the magnet is completed. Further, since the tip portion M2a of the magnetic unit M2 attached to the vertical frame 4 is also fitted into the groove 5a provided in the vertical frame 5, the vertical frames 5 and 4 can be positioned in the horizontal direction. It is said.

In this temporary connection state, the lock pin R2 of the vertical frame 4 penetrates into the large-diameter hole portion R1a1 in the engagement hole R1a of the interlocking bar R1 held by the vertical frame 5. When a rotation operation force is applied to the operation body R41 of the lock operation unit R4 from the outside in this state, the rotation operation force is transmitted to the interlocking bar R1 via the pinion R42 and the rack R43, and the interlocking bar R1 is in the unlocked position. It moves upward from (q) to the lock position (p) and is held at the lock position (p) by the auxiliary magnet R3. At the lock position (p), as shown in FIG. 15, the lock pin R2 engages with the narrow slit portion R1a2 of the engagement hole R1a, and the large diameter portion R21 of the lock pin R2 comes from the engagement hole R1a. It is forbidden to get out. That is, the vertical frames 5 and 4 are locked by the mechanical lock mechanism R so as not to be detached.

In the member connection structure having such a configuration, both vertical frames 5, 4 are first temporarily connected by the magnet type temporary fixing mechanism M, and then are connected in earnest by the mechanical lock mechanism R. Therefore, the assembly work of the peripheral wall panels 1A and 1B can be efficiently performed, and the connection strength can be increased.

Here, FIG. 9 shows one connection target member (vertical frame 5 on the right side of the front view of the first peripheral wall panel 1A) and the other connection target member (second peripheral wall panel) in order to show the magnet type temporary fixing mechanism M. FIG. 10 is a front view showing a part of both vertical frames 5 and 4 where the magnetic temporary fixing mechanism M exists in a state where the vertical frame 4) on the left side of the front view of 1B is separated from the vertical frame 4). , FIG. 9 is a cross-sectional view taken along the line YY in FIG. FIG. 11 is a diagram corresponding to FIG. 9 in a state where both vertical frames 5 and 4 are connected, and FIG. 12 is a diagram corresponding to FIG. 10 in the same state. FIG. 13 is a front view showing a part of the main parts of the vertical frames 5 and 4 in a state where the vertical frames 5 and 4 are separated from each other in order to show the mechanical lock mechanism R. , FIG. 13 is a cross-sectional view taken along the line ZZ in FIG. FIG. 15 is a diagram corresponding to FIG. 13 in a state where both vertical frames 5 and 4 are connected, and FIG. 16 is a diagram corresponding to FIG. 14 in the same state. FIG. 17 is an exploded perspective view showing a connection mode of the first and second peripheral wall panels 1A and 1B, and FIGS. 18 and 19 show a magnetic temporary fixing mechanism M and a mechanical locking mechanism R, respectively. It is a figure which showed the main part in FIG. 17 enlarged.

That is, in this embodiment, the magnetic temporary fixing mechanism M temporarily connects the vertical frames 5 and 4 in a state where both vertical frames 5 and 4 are positioned in the biaxial directions (horizontal direction and vertical direction). Therefore, it is unlikely that the position will be displaced or the shape will be lost in the temporarily connected state, and the peripheral wall panels 1A and 1B can be efficiently assembled without necessarily relying on a highly skilled worker.

Moreover, since the positioning of both vertical frames 5 and 4 is completed in the temporarily connected state, the relative positional relationship between the lock pin R2 of the mechanical lock mechanism R and the interlocking bar R1 is also as intended at the time of design. Therefore, it is possible to prevent or suppress the occurrence of a problem that it takes time to engage the lock pin R2 with the interlocking bar R1 and that the interlocking bar R1 does not operate smoothly due to mutual misalignment.

The above describes the member connection structure between the right vertical frame 5 (one connection target article) of the first peripheral wall panel 1A and the left vertical frame 4 (the other connection target article) of the second peripheral wall panel 1B. However, the member connection structure according to the present invention is also applied to other parts.

Structure, member connection structure between the right vertical frame 5 (one connection target article) and the corner frame 2C (the other connection target article) of the sixth peripheral wall panel 1F, corner frame 2C (one connection target article) And the member connection structure between the 7th peripheral wall panel 1G and the left vertical frame 4 (the other article to be connected), the right vertical frame 5 (one object to be connected) of the 7th peripheral wall panel 1G, and the 7th Member connection structure with the left vertical frame 4 (the other article to be connected) of the peripheral wall panel 1F of 8, the right vertical frame 5 (one object to be connected) and the corner frame 2D (the other article to be connected) of the eighth peripheral wall panel 1F. The present invention is also applied to the member connection structure between the connection target article, and the corner frame 2D (one connection target article) and the left vertical frame 4 of the first peripheral wall panel 1A (the other connection target article). Has been done. Here, "left and right" indicate the directions when the panels 1A to 1H are viewed from the outer surface side.

Since each of these member connection structures is based on the member connection structure between the peripheral wall panels 1A and 1B described above, the same reference numerals are given to the corresponding parts, and the description thereof will be omitted.

The member connection structure of the present invention is not limited to the connection between panels, in other words, the connection between frames constituting the panel, and can be applied to various fields without departing from the gist of the present invention. It is possible.

Further, the configuration of the magnet type temporary fixing mechanism is not limited to that of the illustrated embodiment, and for example, the magnet unit may be one in which a magnet is held in an exposed state by a magnet holder. However, according to the structure in which the magnet is held so as to be wrapped by a resin magnet holder as in the illustrated embodiment, it is possible to effectively prevent the magnet itself and the member on the other side from being scratched due to collision or the like. ..

Further, since the tip of the magnet unit is projected outward from the joint surface, not only can the magnet be made relatively large to increase the magnetic force for temporary holding, but also the tip of the magnet can be grooved and magnetized. By engaging the receiver with a taper, positioning of both vertical frames in the biaxial directions (direction orthogonal to the groove and groove extension direction) can be performed at once, and temporary assembly can be performed smoothly and reliably. In particular, in this embodiment, since the tip portion M2a of the magnet unit M2 has a side view table shape, when the tip portion M2a is fitted to the side view U-shaped magnet receiver M1, both vertical frames 5 and The vertical positioning of 4 is forcibly performed. Therefore, even if there is some unevenness on the floor, both vertical frames 5 and 4 can be positioned at the same height level and temporarily connected. Therefore, the operation of the mechanical lock mechanism R becomes smooth, and the assembly work can proceed efficiently.

Of course, the configuration of the mechanical lock mechanism is not limited to the one described above, but according to the combination of the Dharma hole-shaped engaging hole and the lock pin having a large diameter portion as in the above embodiment, the interlocking mechanism is performed. The bar can be made into a relatively thin plate, and can be easily stored in the groove of the frame. Further, the mechanism for moving the interlocking bar forward and backward is not limited to the one shown in the illustrated example, but since the rack is formed by using a plurality of rectangular through holes formed in the interlocking bar, the number of parts is reduced. It becomes possible.

Further, the number and arrangement positions of the auxiliary magnets are not limited to those shown in the illustrated example, but the other connection is made corresponding to the end of the magnetic material interlocking bar held by one connection target member. If a single auxiliary magnet is provided on the target member and the end of the interlocking bar is set to approach the auxiliary magnet at the locked position and away from the auxiliary magnet at the unlocked position, the interlocking bar is locked. It can be held in a position and can effectively prevent the lock-like body of the mechanical lock mechanism from coming off due to vibration or the like. Further, according to such a configuration, when the interlocking bar is moved to the non-locked position and disassembled, the suction state between the auxiliary magnet and the interlocking bar is released. Therefore, in the locked position, the auxiliary magnet exerts a function of strengthening the bonding between the vertical frames, and in the non-locking position, the bonding force strengthening state due to the magnetic force of the auxiliary magnet disappears or weakens. Therefore, it is convenient when disconnecting the vertical frame.

In addition, various modifications may be made as long as the gist of the present invention is not impaired.
