Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel connecting structure for forming a partition panel or the like which is preferably used in an office or the like.

[0002]

2. Description of the Related Art For example, in a partition panel used as a partition for partitioning a space in an office or the like, it is common to use a plurality of panels continuously in a plane direction. As a panel connecting structure for forming such a partition panel, a pillar is interposed between adjacent panels, and a plurality of slits formed on the side surfaces of the pillar extending from the upper and lower ends are projected from the side end surface of the panel. Some panels connect adjacent panels by hooking a hooking claw.

[0003]

However, in the case where the columns are interposed between the adjacent panels as described above, particularly when a large number of panels are connected in series, a large number of columns are required. The cost is inevitably high, and it is laborious to carry the goods from the factory to the office. Therefore, there is a demand for a panel connecting structure that has a simple structure and that can connect adjacent panels without interposing columns.

By the way, as a connecting structure for connecting adjacent panels without interposing columns, for example, a concave portion is formed in a vertical frame member forming a side end face of the adjacent panels, and between the vertical frame members. A panel is connected by interposing a connecting member having a pair of protrusions that fit into the recesses, and screwing a bolt inserted from the inner side surface of the vertical frame member into a screw hole provided in the protrusion of the connecting member. Or a concave groove extending in the vertical direction is formed on the side end surface of the panel, and both end portions of a plate-like connecting member having substantially the same length as the panel are inserted from above into the concave groove, and the connecting member is interposed therebetween. It is conceivable to connect adjacent panels with each other.

However, the former must attach the surface materials to the front and rear surfaces of the panel after connecting the vertical frame members with each other by bolts, which makes the work on site extremely complicated. On the other hand, in the latter case, since the connecting member becomes long by itself, a large insertion resistance is involved when the connecting member is inserted along the side edge of the panel to the complete insertion position. Moreover,
At the initial stage of insertion, since the connecting member must be temporarily raised to a position higher than the upper end of the panel in the standing state, there is a risk that the upper end of the connecting member may be caught on the ceiling or the like and interfere with the insertion work. It's not something.

[0006]

In view of the above-mentioned problems, the present invention connects adjacent panels by a connecting member inserted between the panels along the thickness direction of the panels.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION That is, according to the present invention, the side end surfaces of adjacent panels are connected to each other through a connecting member, and the connecting member is provided between adjacent panels in the thickness of the panel. Insert along the direction and the bottom surface is the panel
Of the engaging hole formed on the side end face of the
Darken to a position, coupling of the panels, characterized in that so as to connect to each other the side edge surfaces of adjacent panels by engaging the engaging claw which is disposed at both ends of the connecting member to the engaging hole It is a structure.

With such a structure, the side end surfaces of the panels to be connected to each other are butted against each other with a predetermined gap, and the connecting member is inserted through the gap along the thickness direction of the panel, and both ends thereof are inserted. By engaging the engaging claw provided in the portion with the engaging hole formed in the side end surface, the panels can be connected without interposing the support. Therefore, it is possible to reduce the cost by omitting the columns and to reduce the complexity of carrying in. Further, since the connecting member is inserted between the panels along the thickness direction of the panel, it is possible to configure the connecting member from a plurality of members having a small height, and to reduce the resistance when inserting the connecting member. It is possible to make it small and easy to handle. further,
Since the working direction at the time of connection is the thickness direction of the user's body, the work such as insertion is very easy to perform as compared with the case of working along the surface direction. Further, since the panel as a finished product to which the surface material is attached can be connected, the work on site becomes very easy.

As a specific embodiment for engaging the connecting member with the engaging hole, the connecting member is a plate-like member having a face plate portion, and the face plate portion is provided on a panel. After being inserted between adjacent panels in an upright state so as to be substantially parallel to the side end face, the face plate portion is rotated by about 90 degrees to be in a horizontal state orthogonal to the side end face of the panel and the engaging claw is formed in the engaging hole. The thing to be engaged is mentioned.

In the width direction and the depth direction of the panel after connection
To prevent movement, the engagement claw should be
The engaging recesses are provided at both ends in the opposite direction.
It is desirable to tightly engage the concave and convex portions with the opening edge in the depth direction of the dowel . In order to obtain a smooth insertion property of the connecting member into the engaging hole and a reliable connected state, the engaging hole is inserted such that the distance between the opening edges facing each other in the depth direction is larger than the depth dimension of the engaging claw. It is preferable to include a region and an engagement region formed below the insertion region and opposed to each other in the depth direction so as to closely and unevenly engage with the engagement recess of the engagement claw.

In a preferred embodiment of the connecting member and the engaging hole, the engaging claws are arranged in pairs in the depth direction of the connecting member, and the engaging hole is the engaging hole. An example is one in which the side end surfaces of the panel are arranged in pairs so as to correspond to the claws. In order to facilitate the connecting work, it is desirable that the connecting member be held by a detachable connecting member holder and be inserted between adjacent panels to be rotated.

As a specific embodiment of the connecting member holder in this case, the connecting member holder holds the connecting member and can be inserted between adjacent panels, and a user holds it. An example of the device includes an operation unit that can be rotated. When a plurality of panels are arranged in series to form a partition panel or the like, it is desirable to support the upper and lower ends of the panels by upper and lower support members.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the case where the panel connection structure of the present invention is applied to a partition panel A used as a partition for partitioning a space in an office or the like will be described.

As shown in FIGS. 1 to 3, the partition panel A includes a top rail 1 which is an upper support member fixed to a top plate surface C, and a lower support member fixed to a floor surface F. It is provided with a barrel baseboard 2 and a plurality of panels 3 that are continuously provided between the top rail 1 and the baseboard 2 along the surface direction. As shown in FIGS. 2 and 3, the ceiling rail 1 includes a top plate 11, a side wall 12 vertically extending from the front and rear edges of the top plate 11, and an inward projection from the side wall 12. The top plate 11 is fixed to the top surface C with bolts or the like, which is a substantially U-shaped aluminum extruded material having an opening at the bottom, which includes projections 13 that are attached to the front and rear surfaces of the panel 3.

The baseboard 2 has a bottom plate 21 and side walls 22 that stand upright from the front and rear edges of the bottom plate 21 in a vertical direction.
Is fixed to the floor surface F with bolts or the like. Between the side walls 22, a U-shaped member 4 having a top plate 41 and a side wall 42 hanging vertically from the front and rear edges of the top plate 41 and having an opening at the bottom is formed on each panel 3. It is fitted in a position where it can support two places in the width direction. And the U-shaped member 4
The height of the panel 3 is adjusted by screwing the adjuster 5 that supports the panel 3 into the screw hole 43 provided in the top plate 41, and by moving the adjuster 5 forward and backward with respect to the screw hole 43. I am trying.

As shown in FIGS. 2 to 4, the panel 3 has a paper honeycomb core 31 made of paper and first and second metallic surface materials 32 and 33 attached to both front and rear surfaces thereof. so,
A cloth cloth is attached to the outer surfaces of the first and second surface materials 32 and 33 to adjust the appearance. The first surface material 32 is formed by integrally bending the outer wall 321 attached to one outer surface of the paper honeycomb core 31 and the left and right edge portions of the outer wall 321 by bending them by approximately 90 degrees and integrally. The left and right side walls 322 that form the side end surface 3a, and the left and right side walls 32
The bent wall 323 is bent from the front end of the second plate 2 by about 90 degrees and extends along the width direction, and is further bent and bent by about 90 degrees toward the inside of the panel 3. The second surface material 33 includes an outer wall 331 attached to the other outer surface of the paper honeycomb core 31 and left and right side walls 332 attached to side surfaces of the paper honeycomb core 31. Also,
As shown in FIG. 2, a cutout 322a that opens downward is provided at the lower ends of the left and right side walls 322 of the first surface material 32, and the panel 3 is provided between the top rail 1 and the skirting board 2. In this case, the opening edge of the notch 322a is the side wall 2 of the baseboard 2.
2 is fitted. At this time, the paper honeycomb core 3
The lower surface of 1 is attached and supported on the head 51 of the adjuster 5.

In this embodiment, in this embodiment, a slit 6 which is an engaging hole is formed in the side end surface 3a of the adjacent panel 3, and the panel 6 adjacent to the slit 6 is formed.
The adjacent panel 3 is connected by engaging the connecting member 7 inserted along the thickness direction of the panel 3 between them. As shown in FIGS. 4 and 5, the connecting member 7 is a thin plate-shaped face plate portion 71 having a substantially rectangular shape in a plan view.
And a pair of notches 72 formed at both ends in the depth direction of the face plate portion 71 and opening outward, and engaging claws 73 protruding in pairs in the depth direction from both ends in the width direction of the face plate portion 71.
And engaging recesses 74 formed at both ends in the depth direction of the neck portion of the engaging claw 73.

The slit 6 is, as shown in FIGS.
On the left and right side walls 322 of the first surface material 32 of the panel 3,
A plurality of members that are arranged side by side in a pair in the depth direction are bored across the upper and lower ends. The slit 6 has an upper region 61 having an opening formed in a substantially rectangular shape in the upper portion, an engagement region 62 formed in a lower portion having an opening in a substantially rectangular shape, and these upper regions 6
1 and the engaging area 62, and has an insertion area 63 wider than the areas 61 and 62. Insertion area 63
Is formed continuously from the upper region 61 and the engaging region 62 by gradually increasing the opening area. The insertion area 63
The separation distance between the opposing opening edges 65 formed by the above is set to be larger than the maximum depth dimension of the engaging claw 73 so that the engaging claw 73 of the connecting member 7 can be easily inserted.
On the other hand, the separation distance between the opposed opening edges 66 forming the engagement region 62 is determined by the inner end 74 a of the engagement recess 74.
It is set to be approximately equal to the depth dimension between, and at the engagement position,
The opening edge 66 tightly engages with the engagement recess 74.
That is, when the engaging claw 73 of the connecting member 7 is inserted into the slit 6, the slit 6 can effectively prevent the interference between the connecting member 7 and the opening edge 65 to facilitate the insertion work. As described above, if the lower surface of the connecting member 7 is inserted to the position where the lower surface of the connecting member 7 contacts the upward opening end face 67 of the slit 6 after insertion, the engaging recess 74 becomes the opening edge 66 of the engaging region 62. It is configured so as to prevent the movement of each panel 3 in the width direction and the depth direction by engaging the concave and convex portions.

The connecting member holder 8 is a hook-like member that can be attached to and detached from the connecting member 7, and has a rod-shaped holding portion 81 capable of holding the connecting member 7 and a base end 81a of the holding portion 81.
Is a thin plate having a rectangular shape in a plan view which is integrally provided with the operation part 82 which can be gripped and operated by a user. The holding portion 81 has a concave groove 83 formed on the tip end 81b side and having an opening on the tip end surface and on the side. The separation distance between the facing surfaces 83 a formed with the groove 83 is slightly larger than the thickness of the connecting member 7. Further, from the base end surface 83b formed with the recessed groove 83, a protrusion 84 that can fit with the notch 72 of the connecting member 7 is provided.
When the connecting member 7 is held in the connecting member holder 8, the connecting member 7 is inserted between the facing surfaces 83a formed with the concave grooves 83, and the notches 72 are fitted to the ridges 84.

As shown in FIGS. 3 and 4, a rubber seal material 9 is press-fitted between the adjacent panels 3 to seal the joints formed between the adjacent panels 3, as shown in FIGS. I am trying. A description will be given of a work process in the case of forming the partition panel A by connecting the adjacent panels 3 to each other in the configuration as described above. First, with the panel 3 inclined, the upper end 3b thereof is inserted between the protrusions 13 of the ceiling rail 1 to
The panel 3 is once lifted up to the position where the lower end portion 3c of the baseboard 2 can be fitted on the baseboard 2, and then the panel 3 is dropped to a position where the lower surface of the paper honeycomb core 31 contacts the head portion 51 of the adjuster 5. In addition, the adjuster 5 is screwed on the U-shaped member 4 in advance so that the head 51 is located at a predetermined height position. In this way, after the plurality of panels 3 are continuously provided between the top rail 1 and the skirting board 2, a slight gap is formed between the adjacent panels 3 so that the connecting member holder 8 can be inserted. The connecting member 7 is provided around the insertion area 63 of the slit 6.
The connecting member holder 8 holding the is inserted. At this time,
As shown in the middle phantom line and in FIG. 7, the face plate portion 7 of the connecting member 7
The connecting member holder 8 is inserted between the side end surfaces 3a of the panel 3 in a standing state in which the panel 1 is substantially parallel to the side end surface 3a of the panel 3. Then, with the connecting member 7 held so as to be positioned in the insertion region 63 of the slit 6, as shown in FIG. 6, the operating portion 82 of the connecting member holder 8 and the face plate portion 71 of the panel 3 side are provided. The engaging claw 73 of the connecting member 7 is rotated by approximately 90 degrees so as to be horizontal and orthogonal to the end face 3a.
Is inserted into the insertion area 63. In addition, the engaging claw 73
However, the separation distance between the panels 3 that can be properly inserted into the insertion region 63 and the engagement recess 74 can be properly engaged with the engagement end portion 66 is larger than the diameter of the holding portion 81 of the connecting member holder 8. Since it is slightly large, if the separation distance is too large, etc., it is properly adjusted at the time of insertion. Then, with the connecting member 7 kept horizontal, as shown in FIGS. 6 and 9,
The insertion area 63 is lowered to the engagement area 62. At this time, since the opening edge between the areas 63 and 62 is tapered, the engagement recess 74 of the engaging member 7 is suitable for the opening edge 66 of the engagement area 62 while correcting a slight positional deviation. Will be disposed at a position that engages with. Then, the connecting member holder 8 is lowered to the position where the lower surface of the connecting member 7 contacts the upward opening end face 67 of the slit 6. At this position, as shown in FIG. 8, the engagement recess 74 of the connecting member 7 is
It tightly engages the opening edge 66 of the engagement region 62, and the connection between the adjacent panels 3 is completed. Further, at this time, the concave and convex engagement between the engaging concave portion 74 and the opening edge 66 prohibits the movement of the panel 3 in the width direction and the depth direction. After that, the connecting member holder 8 is pulled out from between the panels 3 and a sealing material 9 is press-fitted between the adjacent panels 3 to seal the joints between the panels 3.

With such a structure, since the adjacent panels 3 are connected to each other via the connecting member 7, it is possible to omit the support columns, realize the cost reduction and carry-in. It is possible to reduce complexity. Furthermore, since the connecting member 7 is composed of a plurality of members having a small height, and is inserted between the panels 3 along the thickness direction of the panels 3 to engage with the slits 6, the connecting member 7
Can be made easy to handle with little resistance during insertion. Further, since the working direction at the time of connection is the thickness direction of the user's body, the work is very easy to perform as compared with the case of working along the surface direction. Further, since the panel 3 as a finished product to which the surface material 32 is attached can be connected, the work on the site becomes very easy.

The connecting member 7 is a plate-like member having a face plate portion 71, and the face plate portion 71 is placed between the adjacent panels 3 in a standing state such that the face plate portion 71 is substantially parallel to the side end surface 3a of the panel 3. After that, the face plate portion 71 is rotated by about 90 degrees so as to be in a horizontal state orthogonal to the side end surface 3a of the panel 3, and the engaging claw 73 is engaged with the slit 6. The panel 3 can be easily connected only by inserting the connecting member 7 using the slight gap formed and rotating.

The engaging claw 73 has engaging recesses 74 at both ends in the depth direction of its neck, and the engaging recesses 74 engage with the opening edge 66 of the slit 6 in the depth direction in a concavo-convex manner. Since the movement of the panel 3 in the width direction and the depth direction is prohibited, the movement of the panel 3 after the connection can be effectively prevented. The slit 6 has an opening edge 65 facing in the depth direction.
An insertion region 63 having a distance between them that is larger than the depth dimension of the engagement claw 73, and an opening edge 66 that is formed below the insertion region 63 and faces in the depth direction are formed in the engagement recess 64 of the engagement claw 63. Since the engaging region 62 for tightly concavo-convex engagement is provided, the connecting member 7 is rotated from the upright state to engage the engaging claw 7.
3 is inserted into the slit 6, the connecting member 7 and the opening edge 6
Interference with 6 can be effectively prevented, and smooth insertion work can be performed. Further, after the insertion, if the connecting member 7 is dropped downward, the engaging concave portion 74 and the opening edge 66 are properly engaged with each other, and a reliable connected state can be obtained.

The engaging claws 73 are arranged in pairs in the depth direction of the connecting member 7, and the slits 6 are arranged to face the side end surface 3a of the panel 3 in correspondence with the engaging claws 63. Since it is arranged so that it is easy to hold the connecting member 7 in a horizontal state. Since the connecting member 7 is held by the detachable connecting member holder 8 and is inserted between the adjacent panels 3 so as to be rotated, it is very easy to insert the connecting member 7 between the panels 3 or engage the engaging work. It can be easy.

The connecting member holder 8 is replaced by the connecting member 7
A holding portion 81 that holds the above and can be inserted between the adjacent panels 3.
And the operation section 82 which can be gripped and rotated by the user, the operability is very good. Since the upper and lower ends of the panel 3 are supported by the top rail 1 and the skirting board 2, rigidity can be maintained when a plurality of panels 3 are continuously arranged to form a partition panel or the like.
Especially effective.

The specific structure of each unit is not limited to the above-mentioned embodiment. For example, in the present embodiment, the slits 6 are arranged side by side in pairs in the depth direction, but the present invention is not limited to this, and one slit may be provided in the depth direction. Further, in the case where the panel 3 has a pair of surface materials having the same configuration adhered to the front and rear surfaces of the paper honeycomb core 31 and side walls of the surface materials are abutted to each other to form a side end surface of the panel. By providing a slit on the side wall of each surface material, the slits are arranged side by side in a pair in the depth direction, and the panel 3 is connected in the width direction by engaging the connecting member 7 with the slit. In addition to being possible, the surface materials 32 are also connected to each other. Other configurations can be variously modified without departing from the spirit of the present invention.

It is possible to realize and reduce the complexity of carrying in. Further, since the connecting member is inserted between the panels along the thickness direction of the panel, it becomes possible to configure the connecting member from a plurality of members having a small length, and the resistance during insertion is small. Can be easy. Further, since the working direction at the time of connection is the thickness direction of the user's body, the work is very easy to perform as compared with the case of working along the surface direction.
