DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition connection structure which enables easy and proper connection between partitions.

[0002]

2. Description of the Related Art Conventionally, when partitions are connected to each other, a strip-shaped connecting plate is hung between upper end surfaces of adjacent partitions and screwed, or each partition is mounted on a support interposed between the partitions. Is fixed by screwing through a bracket. After the connection, a cover is attached to the upper end surface of the partition, and the upper surface of the partition is hidden by the cover together with the connection plate.

[0003]

However, in such a connection structure, every time the partition is assembled and disassembled, the operation of attaching and detaching screws must be performed. For this reason, there is a problem that the work is not troublesome.

[0004] On the other hand, it has been considered that connecting the partitions via a buckle is an effective means. That is, a structure is adopted in which a buckle is pivotally attached to one partition and a pin is fixed to the other partition, the buckle is engaged with the pin and the buckle is rotated to connect the partitions. It is to be.

[0005] However, the buckle is generally configured to prevent its return by rotating to a position beyond a conceivable point, and as a result, to apply a continuous tightening force to a partition or the like. Therefore, even if the maximum operating force is applied when passing the thought point,
After that, loosening of the tightened state due to the buckle passing through the idea point is unavoidable in principle, and there is a problem that rattling is likely to occur. Conversely, if it is attempted to achieve a tightened state in which looseness is not caused even when loosened, an excessively large maximum operating force is required when exceeding a conceivable point, and the inconvenience that the difficulty of work is doubled arises. Also, after exceeding the thought point, the direction in which the buckle tries to rotate by receiving the reaction force from the panel is reversed, and that direction will match the direction of the operating force previously applied to the buckle Then, there is a danger that the rotation is bounced and a finger or the like is easily pinched. The above-mentioned inconveniences can be said in the same manner when the buckle is released.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a partition connection structure in which partitions can be connected or disconnected easily and appropriately. And

[0007]

In order to achieve the above object, the present invention employs the following configuration.

That is, according to the present invention, in a connection structure in which partitions are connected to each other via a buckle, the buckle can be moved between the buckle and the partition in a region where the turning operation of the buckle is effectively converted as a force for attracting the partitions. A buckle is provided with a lock mechanism for locking the buckle.

In a first specific embodiment, the buckles are pivotally mounted in pairs on a common connecting member.
Engaging portions are respectively formed at positions approaching each other by a rotating operation in the engaging direction, a connecting member is disposed across the partitions, and each buckle is rotated to correspond each engaging portion. And the buckle is locked by a lock mechanism during the engaging operation while gradually engaging the engaged portion formed at the upper end of the partition to be engaged.

In a second embodiment, the buckles are pivotally attached to the upper ends of the respective partitions, and engaging portions are formed at positions approaching each other by a pivoting operation in the engaging direction. , A connecting member having a pair of engaged portions formed at both ends is disposed across the partition,
Rotating each buckle to gradually engage each engagement portion with the engaged portion of the corresponding connecting member, and locking the buckle by a lock mechanism during the engagement operation. .

In a third embodiment, the buckles are pivotally attached to a pair of auxiliary connecting tools connected via an intermediate connecting tool, respectively. In the state where an intermediate connecting member is interposed between the counter pivoting ends of the pair of auxiliary connecting members, they are inserted across the partitions, and each buckle is rotated. , Each engaging portion is engaged with the engaged portion formed at the upper end of the corresponding partition, and further, the auxiliary connecting tool is rotationally biased in a direction of gradually separating the auxiliary connecting tool with the engaging portion as a fulcrum, and One in which the buckle is locked by a lock mechanism during the moving operation is exemplified.

As a fourth embodiment, the buckle is pivotally attached to the upper end of each partition, and the buckle is provided with auxiliary connecting members at positions separated from each other by a rotation operation in the engaging direction. In a state in which the intermediate connector is interposed between the opposite pivotal ends of the two auxiliary couplers, each buckle is pivoted, and the pivotal urging is performed in a direction to gradually separate the auxiliary couplers, A device in which the buckle is locked by a lock mechanism during the rotation operation is exemplified.

In addition, the normal buckle may be configured to be locked by the lock mechanism just before the point beyond the expected point.

[0014] As the engagement structure, the engagement portion is an engagement recess, and the engaged portion is a pin, or the engagement portion is a claw,
It is preferable that the engaged portion is a hook hole.

Specific examples of the lock mechanism include an engagement mechanism between a lock arm and a hook hole, an engagement mechanism between a dowel and a recess, and an engagement mechanism between a slide pin and an engagement groove. And a mechanism. In particular, when using an engagement mechanism between the slide pin and the engagement groove, in order to prevent the engagement from being easily released due to rattling of the partition, the inner end of the engagement groove is provided with a buckle release direction. It is effective to provide a notch that extends, slide the slide pin along the engagement groove, and then pull the slide pin into the notch.

In order to improve the appearance at the time of connection, an opening groove extending in the longitudinal direction for inserting a buckle is formed in the upper end surface of the partition, and the opening groove is formed in a state where the partitions are connected by the buckle. It is effective that the lid is sealed by the buckle, and the upper surface of the buckle and the upper end surface of the partition are continuously flush.

In order to position the connection between the partitions more firmly and more accurately, it is effective that the connecting member is taperedly engaged with both partitions to be connected. For this purpose, it is desirable that a part of the rotation of the buckle be converted to a force that deepens the taper engagement between the connecting member and the partition.

[0018]

With this configuration, as the buckle is rotated, the force for pulling the partitions gradually increases as the amount of rotational displacement increases, and the buckle is locked by the lock mechanism when it reaches a certain rotational position. Is done. Therefore, there is no inconvenience that the input operating force escapes, and the buckle can be fixed while substantially maintaining the rotational position when the maximum operating force is applied. In this manner, the present invention minimizes the loosening of the tightening force due to the operation of the buckle, reduces the occurrence of rattling between the partitions, and at the same time, increases the maximum operating force more securely than before. It will be reduced. Also, since the direction in which the buckle is operated and the direction in which the buckle tries to rotate are always in opposition, there is no danger that the buckle will suddenly rotate beyond the expected point, and the lock operation or unlock operation must be performed. It can be done smoothly and safely.

[0019]

As shown in FIGS. 1, 4 and 5, the connecting member 3 has a channel-shaped main body comprising a side wall 31 and a bottom wall 32, and a lid 33 provided on the side wall 31. doing. The cross-sectional shape of the main body is the upper frame material 1 described above.
2 corresponds to the cross-sectional shape of the groove 12a and the notch 13a of the edge member 13, and the planar shape thereof is
Of the receiving frame 13c. That is, the entire connecting member 3 is formed in the groove 12a through the cutout 13a.
And the lid 33 is placed on the receiving frame 13c. The lid 33 is disposed at a position where the central portion in the longitudinal direction of the connecting member 3 can be partially closed, and the inner periphery of the connecting member 3 is opened upward on both left and right sides of the lid 33. I have. And in the opening,
A pair of buckles 2 are arranged inside the connecting member 3 in a state of facing each other.

As shown in FIGS. 1, 4 and 6, the buckle 2 has a structure in which the upper ends of a pair of side walls 21 are connected via a top plate 22. The buckle 2 is pivotally attached to the side wall 31 of the connecting member 3 via the horizontal pin 23, and approaches each other by a pivoting operation of the buckle 2 in an engagement direction near the pivot point and with the pivot point as a fulcrum. An engagement recess 24 which is an engagement portion is formed at each position. When the buckle 2 is rotated from a release position shown by imaginary lines in FIGS. 1 and 6 to an engagement position shown by solid lines in FIG.
Is gradually and deeply engaged from the side with a pin 12d, which is an engaged portion, which is horizontally mounted on the upper frame member 13.

As shown in FIGS. 1 and 6, the lock mechanism 4 has a lock arm 42 pivotally connected via a pin 41 between the side walls 21 on the opposite side of the buckle 2. The lock arm 42 has protrusions 42a and 42b above and below the center.
A hook portion 42c is formed at the lower end of the hook portion 4b.
2c extends downward through a hole 32a formed in the bottom plate 32 of the connecting member 3. When the connecting member 3 is provided in the groove 12a of the partition 1, the hole 32a is provided at a position communicating with the hook hole 12e formed in the bottom wall 12b. Also, this lock arm 42
It is elastically biased to the position shown in FIGS. 1 and 6 by a not shown torsion spring or the like provided between the buckle 2 and the like.
In order to rotate the lock arm 42, an opening 22a is provided in the top plate 22 of the buckle 2, and a finger or the like is inserted through the opening 22a to make the upper projecting portion 42a of the lock arm 42 anti-elastic. The pressing operation can be performed in the bias direction. Note that a gap is formed between the top plate 22 of the buckle 2 and the lid 33 of the connecting member 3 as an allowance for the buckle 2 to rotate. The top plate 22 of the buckle 2 and the lid 33 of the connecting member 3 are flush with each other.

In the drawing, reference numeral 34 denotes a connecting member
This is a relief groove for avoiding interference between the connecting member 3 and the pin 12d when inserted into the inside 2a.

Next, a procedure for connecting the partitions 1 according to the present embodiment will be described. First, the side edges of the partition 1 are brought close to each other in the direction of the arrow as shown in FIG.
As shown in FIG. 2, the side frame members 14 are brought into a state of abutting each other. Next, with the buckle 2 raised to the release position indicated by the imaginary line in FIGS. 1 and 6, the connecting member 3 is laid over the opening groove 12 a via the rectangular notch 13 a formed by the two partitions 1. Charge. At this time, in FIGS. 4 and 6, the side wall 31 and the bottom wall 32 of the connecting member 3 are disposed along the inner surface of the upper frame member 13 of the partition 1, and the lid 33 is attached to the receiving frame 13 c of the edge member 13.
Attached to In this state, the buckle 2 is rotated to the engagement position indicated by the solid line in FIGS. This operation may be performed successively for each buckle 2 or may be performed simultaneously. At that time, as the buckle 2 rotates, the engagement recess 24 gradually engages with the pin 12d fixed at the upper end of the partition 1, and as a result,
Since the partitions 1 are urged toward each other via the pins 12d, the degree of adhesion to the side frame members 14 is increased. When the buckle 2 reaches a certain rotation position, a hook 42 formed at the lower end of the lock arm 42 is formed.
c is a hook hole 12 opening at the bottom wall 12b of the groove 12a.
e, the lock arm 42 is gradually inserted into the hook hole 12e while being rotated in the anti-elastic bias direction. Then, at a position where the hook portion 42c has passed through the hook hole 12e, the lock arm 42 is rotated in the elastic biasing direction by the torsion spring, and is engaged with the hook hole 12e in a state where it cannot be pulled out. At this point, the partitions 1 are strongly connected via the connecting member 3. At this time, as shown in FIG. 6, the top plate 22 of the buckle 2 and the lid 33 of the connecting member 3 are connected to the edge member 1 of the partition 1.
3 and are arranged substantially flush with each other.

When the buckle 2 is released, a finger is inserted through the opening window 22a while the buckle 2 is pressed down, and the lock arm 42 is urged in the anti-elastic bias direction.
If the force applied to the buckle 2 is gradually reduced in this state, the buckle 2 starts to rotate due to the reaction force received from the partition 1 in the direction of the release position, whereby the hook portion 42c of the lock arm 42 becomes a hook hole. 12e, and the buckle 2 is further rotated to return to the release position shown by the imaginary line in FIGS.

With the above-described partition connection structure, in the process of rotating the buckle 2, the rotational displacement is always converted to a force for effectively attracting the partitions 1, so that the operating force once input escapes. There is no inconvenience and the buckle 2 can be fixed by the lock mechanism 4 while substantially maintaining the rotational position when the maximum operating force is applied. For this reason, according to this embodiment, the loosening of the tightening force due to the operation of the buckle 2 can be suppressed as much as possible, and the occurrence of rattling between the partitions 1 is reduced, and the connection state is assured. can do. Accordingly, the connection can be completed with a smaller maximum operation force than before, and the operability is also improved. In addition, since the direction in which the buckle 2 is operated and the direction in which the buckle 2 tries to rotate due to the reaction force received from the partition 1 are always in opposition as described above, it is as if the buckle 2 exceeded the expected point. Therefore, there is no danger of sudden rotation, and the lock operation or the unlock operation can always be performed smoothly and safely. Furthermore, since the connection state is realized by the pair of buckles 2, the functional beauty as a left-right symmetric structure is excellent, and the connection of the partition 1 can be performed even when one of the buckles 2 is in a use position where it is difficult to operate. An effect that can be surely released is also provided. Furthermore, since the top plates 33 and 22 are flush with the upper surface of the edge frame member 13 with the connecting member 3 attached and the buckle 2 fixed at the engagement position, a special cover is required. It is not necessary to attach it, and it also has an advantage that the appearance can be improved at the same time when the connecting operation is completed. Of course, it is needless to say that the above-mentioned premise provides an excellent operational effect that the connection or disconnection can be easily realized only by operating the buckle 2.

In this embodiment, a connection structure similar to that described above is adopted between the partition 1 and the column 5 provided at the end. The connection structure is shown in FIGS. 2, 3, 5, and 7, and as shown in the cross section of FIG. 8, a single buckle 2 is provided in the connection member 6, and one end of the connection member 6 itself is provided. Form a claw 61 that engages with the engaging portion 51 of the column 5. Then, with the claw 61 engaged with the engaging portion 51 of the support 5 from above, the support 5 and the partition 1 are pulled by rotating the buckle 2 as described above,
The connecting operation can be completed by engaging the lock arm 42 with the hook hole 12a. For this reason, even if it is applied mutatis mutandis between the column 5 and the partition 1, the effect of quickly, safely and reliably performing the connection work is exhibited. Reference numeral 62 denotes a cover attached to the upper end of the column.

<Second Embodiment> FIGS. 9 and 10 show an example in which the partition connection structure employed in the first embodiment can be applied to partitions having different structures. That is, the partition 101 in FIG.
Is different from the above embodiment only in the configuration of the partition 1 and the side frame members 14 (posts). That is, in the above-described embodiment, the side frame member 14 of the partition 1 has a structure in which the column 15 is divided in half, but in this embodiment, the side frame member of a complete column shape is formed on one side edge of the partition 101 from the beginning. On the other side edge side, no side frame material is provided. And the adjacent partition 1
When one side edge of 01 is abutted on the other side edge, the side frame member 114 is interposed between the partitions 101 as a support, and exhibits a function of assisting the partition 101 independence. Since the groove 112a, the pin 112d, the hook hole 112e, and the like can be formed in the same manner for the partition having such a structure, the buckle built-in connection member 103 having the same structure as that of the above-described embodiment is applied in exactly the same manner. Is possible.

<Third Embodiment> The partition connection structure shown in FIGS. 11 to 16 has basically the same structure as that of the first embodiment. The structure and the structure of the lock mechanism are different. That is, in the first embodiment, as shown in FIG.
On the buckle 2, engagement recesses 24 as engagement portions are respectively formed at positions approaching each other by a rotation operation in the engagement direction, and the connecting member 3 is disposed across the partition 1. Is rotated so that each of the engagement recesses 24 is gradually and deeply engaged with the pin 12d as an engaged portion fixed to the upper end of the corresponding partition 1, and the configuration of the lock mechanism 4 during the engagement operation. A hole 12e in which a lock arm 42 as an element is formed at the upper end of the partition 1.
It was configured to engage with. On the other hand, in the present embodiment, on the buckle 202, the pawls 224, which are engaging portions, are formed at positions approaching each other by a pivoting operation about the pin 223 in the engaging direction.
Each buckle 202 is rotated in a state in which the hook holes 2 are formed at the upper ends of the corresponding partitions 201 while the buckles 202 are arranged between the partitions 201.
12d, the dowels 242 constituting the lock mechanism 204 are engaged with the concave portions 231a formed in the connecting member 203 during the engagement operation. The dowel 242 protrudes from the outer surface of the side wall 221 of the buckle 202, and the recess 231a is
03 is provided on the inner surface of the side wall 231.

Even in such a structure, the buckle 20
2 is rotated, the pawl 224 is increased as the rotational displacement increases.
Urges the partitions 201 toward each other via the hook holes 212d.
The buckle 202 is locked via the lock mechanism 204 when the pulling force with respect to 01 gradually increases and reaches a certain rotation position. Therefore, also in this embodiment, there is no inconvenience that the input operation force escapes, and the buckle 202 can be fixed while substantially maintaining the rotation position when the maximum operation force is applied. And, as in the first embodiment,
The loosening of the tightening force due to the operation of the buckle 202 is suppressed as much as possible, the occurrence of rattling between the partitions 201 is reduced, the connection state is ensured, and the maximum operating force at the time of connection is lower than before. The buckle 202 suddenly turns beyond the expected point because the direction in which the buckle 202 operates and the direction in which the buckle 202 tries to rotate are always in opposition. There is no danger that the locking operation or the unlocking operation can be performed smoothly and safely.

The partition 201 can be fixed to the support 205 through the connecting member 206 having the same structure as in the above embodiment. Also, 2
Reference numeral 07 denotes a cover for closing a gap opened between the buckles 202, and is pivotally attached to the buckle 202.

<Fourth Embodiment> In the connection structure of the partitions shown in FIG. 17 and FIG.
Is the upper frame material 41 at the upper end of each partition 401.
An engagement recess 424, which is an engagement portion, is formed between the side walls 421 between the side walls 421 at positions approaching each other by a rotating operation in the engagement direction. I have. Then, a channel-shaped connecting member 40 having a pair of engaged pins 431 fixed to both ends.
3 are arranged so as to straddle between the partitions 401, and each buckle 402 is rotated so that each engagement recess 424 is gradually and deeply engaged with the corresponding pin 431 of the connecting member 403. A cover 425 is pivotally connected to the upper end of the partition 401 in the vicinity of the pin 423 via a pin 413a. An elongated hole 425a provided on the side of the cover 425 is provided at a pivotal end of the buckle 402. The pin 402a is slidably engaged with the provided pin 402a. A lock arm 442 of a lock mechanism 404 having a structure similar to that of the first embodiment is pivotally attached to the lower surface of the cover 425 near the pivot end. During the engagement operation of the buckle 402 with the pin 431, the hook hole 412 in which the lock arm 442 is opened at the upper end of the partition 401 through the hole 432 provided in the connecting member 403.

In such a structure, the buckle 40
When the pivot 2 is rotated, the buckle 402 urges the partitions 401 toward each other via the engaging recess 424 and the pin 431 as the rotational displacement increases, so that the pulling force on the partition 401 gradually increases. Buckle 402 when it comes to a certain rotation position.
Are locked via the lock mechanism 404. for that reason,
Also in this embodiment, there is no inconvenience that the input operation force escapes, and the buckle 402 can be fixed while substantially maintaining the rotation position when the maximum operation force is applied. As in the case of the first embodiment, the loosening of the tightening force due to the operation of the buckle 402 is suppressed as much as possible, and the occurrence of rattling between the partitions 401 is reduced to improve the connection state. Since the maximum operating force at the time of connection is smaller than the conventional one and the operability is excellent, and the direction in which the buckle 402 is operated and the direction in which the buckle 402 tries to rotate are always in opposition, the buckle 402
There is no danger of suddenly turning beyond the expected point, and the locking or unlocking operation can be performed smoothly and safely. In addition, in this embodiment, since the upper end of the partition 401 is covered with the cover 425 at the same time when the rotation of the buckle 402 is completed, there is also an effect that a special exterior work becomes unnecessary.

<Fifth Embodiment> The partition connection structure shown in FIGS. 19 to 21 exemplifies that the present invention is applicable to a normal buckle having a devised point. Specifically, the pair of buckles 502 are each pivotally connected to the auxiliary connecting member 507 via a pin 571. On the opposite end side of the buckle 502, an engagement recess 5 serving as an engagement portion is provided at a position close to each other by a rotation operation in the engagement direction.
24 are formed. Further, connected portions 572 are formed at the opposite pivotal ends of the auxiliary connecting tools 507, and the connected portions 572 are connected to the connecting portions 581 of the intermediate connecting tool 508.

That is, in such a configuration, the auxiliary connector 507 is stretched through the intermediate connector 508 with the rotation of the buckle 502, and the reaction force is converted into a force to draw the partitions 501 together. And
The pulling force gradually increases, and the buckle 502 is locked by the lock mechanism 504 just before the point exceeds the expected point. Therefore, also in this embodiment, there is no inconvenience that the input operating force escapes, and the buckle 502 can be fixed while substantially maintaining the rotation position when the maximum operating force is applied. In this manner, in the present embodiment, the loosening of the tightening force due to the operation of the buckle 502 is suppressed as much as possible, the occurrence of rattling between the partitions 501 is reduced, and a proper connection state is ensured. At the same time, the maximum operation force is smaller than before and the operability is excellent. In addition, since the direction in which the buckle 502 is operated and the direction in which the buckle 502 tries to rotate by the reaction force from the partition 501 are always in opposition, the buckle 5
There is no danger that the 02 will turn sharply beyond the expected point, and the locking or unlocking operation can be performed smoothly and safely.

Also, as in this embodiment, the buckle 502
Are pivotally connected to the auxiliary coupler 507 which is separated from each other,
If the auxiliary connecting members 507 are connected by the intermediate connecting member 508, there is an advantage that the connection can be completed using the same components as described above when connecting the partition 501 and the support 505. 20 and 21
As shown in the figure, the intermediate connector 508 is engaged with the support 505, the auxiliary connector 507 is engaged with the intermediate connector 508, and the buckle 502 can be engaged simply by performing the same operation as described above. is there. Therefore, this embodiment is particularly useful when applied to partitions having various connection directions and structures.

<Sixth Embodiment> The connecting structure of the partitions shown in FIGS. 22 to 24 has basically the same configuration as that of the fifth embodiment. The structure is different. That is, in the above embodiment, the engaging portion is the engaging recess 524 formed in the buckle 502, and the engaged portion is the pin 512d fixed to the upper end of the partition 501. The portion is a claw 624 formed on the buckle 602, and the engaged portion is a hook hole 612 d opened at the upper end of the partition 601. Even with such a structure, the function as the buckle is not different from that of the above-described embodiment, and therefore, the same operational effects as those of the above-described embodiment can be obtained.

<Seventh Embodiment> The connecting structure of the partitions shown in FIGS. 25 to 27 belongs to the fifth embodiment in principle, but the buckle 702 is fixed to the upper end of each partition 701. The pin 723 is pivotally connected via the side wall hole 702a.
An auxiliary connecting member 707 is pivotally connected via a pin 771 to a position where the auxiliary connecting member 707 is separated from each other by a rotation operation in the engagement direction with the pin 723 as a fulcrum. Then, with the intermediate connector 708 interposed between the two auxiliary connectors 707,
Each buckle 702 is rotated to urge the auxiliary coupler 707 in a direction to gradually separate the auxiliary coupler 707, and the pins 723, 723 are rotated.
A locking mechanism 704 composed of a combination of a dowel and a recess just before the pin 771 crosses a thought point on a straight line connecting between the pins.
Is used to lock the buckle 702. That is, the difference from the fifth embodiment is that the buckle 502 of the present embodiment engages with the pin 512d from the middle and starts the rotation operation, whereas the buckle 702 of the present embodiment
Is only pivotally attached to the pin 723 from the beginning and is in a rotatable state. Therefore, the basic operation related to the connection is exactly the same as described in the fifth embodiment, and the same operation and effect can be obtained.

<Eighth Embodiment> The partition connecting structure shown in FIG. 28 is a case where the connecting member 3 is taperedly engaged with both partitions 1 to be connected. This 8th
Since the embodiment has basically the same structure as the first embodiment, the same or corresponding parts are denoted by the same reference numerals and description thereof is omitted. This eighth embodiment is different from the first embodiment in that a downward tapered surface 31 is provided below the side wall 31 of the connecting member 3.
t and the upper frame material 1 of each partition 1
In this case, an upward tapered surface 12t is formed below the second groove 12a. Then, with the connecting member 3 inserted into the groove 12a and the two partitions 1 connected to each other, the downward tapered surface 31t comes into close contact with the upward tapered surface 12t, and the connecting member 3 is taperedly engaged with each partition 1. I have to do it.
