制する第1規制部と、最小対向間隔を規制する第
2規制部とから成る。 On the other hand, within the opposing interval between the supporting parts 13a and 13b, a regulating means is provided for regulating the amount of displacement of the opposing interval between the supporting parts 13a and 13b due to the spring properties of the flexible connecting parts 14a and 14b. . This regulating means includes a first regulating section that regulates the maximum facing distance between the supporting sections 13a and 13b, and a second regulating section that regulates the minimum facing distance.

The upper and lower ends of the vertical piece 19' are the upper and lower support parts 13a,
A predetermined interval (for example, 1 mm) is spaced from each opposing surface of 13b.
次で、上記構成による連結具11を使用して、
両板材A,Bを相互に連結するには、まず、両板
材A,Bに係止部12a,12bが縮径して通り
抜ける大きさの取付孔Ha,Hbを開設する。 Next, using the connector 11 with the above configuration,
In order to connect the two plate materials A and B to each other, first, mounting holes Ha and Hb are opened in both the plate materials A and B to a size that allows the locking portions 12a and 12b to reduce in diameter and pass through.
次に、両板材A,Bの各取付孔Ha,Hbに対し
て各係止部12a,12bを夫々挿入して係止す
る。 Next, the locking portions 12a and 12b are inserted and locked into the mounting holes Ha and Hb of both the plates A and B, respectively.
即ち、各係止部12a,12bを挿入すると、
取付孔Ha,Hbの孔縁に両弾性片16,16が当

することで、両板材A,Bの取付孔Ha,Hbにワ
ンタツチで取付く(第1図)。 That is, when each locking part 12a, 12b is inserted,
Both elastic pieces 16, 16 come into contact with the edges of the mounting holes Ha, Hb, and when pushed strongly, both elastic pieces 16, 1
6 are pushed by the hole edges and advance into the attachment holes Ha and Hb while being bent inwardly toward each other. When both the elastic pieces 16 pass through the attachment holes Ha and Hb, they expand outward due to their elastic force, and the step portions 16' and 16' at their tips are caught on the hole edges, and the supporting portions 13a and
By sandwiching the plates A and B from above and below between the outer surface of the plate 13b, it can be attached to the mounting holes Ha and Hb of both plates A and B with one touch (Fig. 1).
又、このとき、支持部13a,13bの両端の
各当接部17が板材A,Bに夫々当接する。この

が増加すると共に、当接部17が板材A,Bに弾
性的に当接することで、板材A,Bの板厚tに対
する許容性を大きくできる。 Also, at this time, the contact portions 17 at both ends of the support portions 13a and 13b abut against the plate materials A and B, respectively. This abutting portion 17 can be pressed by the plates A and B by setting the distance h in the height direction between the elastic piece 16 and the stepped portion 16' to be slightly shorter than the thickness t of the plates A and B. When the support parts 13a and 13b warp and bend, they elastically abut against the plates A and B due to their restoring force.
Therefore, the locking parts 12a and 12b are pulled in the removal direction, and the step part 16' of the elastic piece 16 is pulled out of each mounting hole.
By biting into the hole edges of Ha and Hb from the outside and increasing the engagement force, the contact portion 17 elastically abuts against the plate materials A and B, thereby increasing the tolerance to the thickness t of the plate materials A and B. You can make it bigger.
こうして、各係止部12a,12bを両板材
A,Bの夫々取付けることで、両板材A,Bは、
連結具11を介して上下に所定間隔だけ離れて対
向保持される(第1図)。 In this way, by attaching the respective locking parts 12a and 12b to both plate materials A and B, both plate materials A and B are
They are held vertically facing each other at a predetermined distance via a connector 11 (FIG. 1).
尚、上方の板材Aの重量が加わるので、その重
量により両可撓連結部14a,14bがパンタグ
ラフ状に少し座屈して、上下の支持部13a,1
3bの対向間隔は僅かに減少する。 In addition, since the weight of the upper plate material A is added, both the flexible connecting parts 14a, 14b buckle slightly in a pantograph shape due to the weight, and the upper and lower supporting parts 13a, 1
The facing distance of 3b is slightly reduced.
又、両可撓連結部14a,14bは、左右対称
構造となつているため、一般的には左右均等に屈
曲し、上下の板材A,Bを平行となる様に保持す
る。 Further, since both flexible connecting portions 14a and 14b have a laterally symmetrical structure, they generally bend evenly on the left and right sides, and hold the upper and lower plates A and B so that they are parallel to each other.
これに対して、板材A,Bに反りや傾きが有る
場合には、両可撓連結部14a,14bが左右非
対称に屈曲することで、反りや傾きが有る板材
A,Bに対しても係止部12a,12bを確実に
取付けることができる。 On the other hand, when the plate materials A and B are warped or tilted, both flexible connecting portions 14a and 14b are bent asymmetrically, so that they are not connected to the warped or tilted plate materials A and B. The stop portions 12a and 12b can be reliably attached.
次に、振動による影響について説明する。 Next, the influence of vibration will be explained.
例えば、外部振動により、上方の板材Aを下方
の板材Bに向つて押し付ける相対的な力が作用し
たと仮定すると、この力により上方の支持部13
aは下向きに押され、両可撓連結部14a,14
bはパンタグラフ状に座屈し、そのバネ性により
両可撓連結部14a,14bは伸長し様とする弾
性復元力を貯える(第5図)。 For example, if it is assumed that a relative force that presses the upper plate material A toward the lower plate material B is applied due to external vibration, this force causes the upper support part 13 to
a is pushed downward, and both flexible connecting parts 14a, 14
b buckles in a pantograph shape, and due to its springiness, both flexible connecting portions 14a and 14b store an elastic restoring force that tends to expand (FIG. 5).
次に、上方の板材Aを押す力が釈放されるか、
押す力より両可撓連結部14a,14bが貯えた
弾性復元力の方が大きくなると、両可撓連結部1
4a,14bは、貯えた弾性復元力により直線的
に伸長し、再度、両可撓連結部14a,14bは
座屈し様とする弾性復元力を貯える(第6図)。 Next, whether the force pushing the upper plate material A is released,
When the elastic restoring force stored in both flexible connecting parts 14a and 14b becomes larger than the pushing force, both flexible connecting parts 1
4a, 14b expand linearly due to the stored elastic restoring force, and again both flexible connecting portions 14a, 14b store the elastic restoring force that tends to buckle (FIG. 6).
こうして、両可撓連結部14a,14bが座
屈、伸長を繰り換えすことで振動を減衰して吸収
し、一方の板材A,Bに発生乃至は作用した振動
を、他方の板材A,Bに伝達しない様に作用す
る。 In this way, both the flexible connecting portions 14a and 14b repeatedly buckle and expand, thereby attenuating and absorbing vibrations, and the vibrations generated or acting on one plate material A, B are transferred to the other plate materials A, B. It acts in such a way that the signal is not transmitted.
一方、両板材A,Bの対向間隔が必要以上に押
し縮められると、両可撓連結部14a,14bは
パンタグラフ状に座屈するが、このとき、一方の
可撓連結部14aから突出したT字形の突片19
の縦片19′の上端と下端が、両板材A,Bの上
下に相対向する対向面に夫々突き当ることで、両
板材A,Bの最小対向間隔を規制する(第5図)。 On the other hand, if the opposing distance between the two plate materials A and B is compressed more than necessary, both the flexible connecting parts 14a and 14b buckle in a pantograph shape, but at this time, the T-shape protruding from one of the flexible connecting parts 14a protrusion 19
The upper and lower ends of the vertical pieces 19' abut against the vertically opposing surfaces of the plates A and B, respectively, thereby regulating the minimum spacing between the plates A and B (FIG. 5).
これにより、両可撓連結部14a,14bが必
要以上に座屈して折れたり、塑性変形するのを未
然に防止できる。尚、両板材A,Bの最小対向間
隔は、縦片19′の上端及び下端と板材A,Bと
の間の隙間の間隔を決定することで自由に設定可
能で、しかも、該隙間を広狭することで最小対向
間隔を容易に変更可能である。 This can prevent the flexible connecting portions 14a, 14b from buckling and breaking or plastically deforming more than necessary. The minimum spacing between the two plates A and B can be freely set by determining the gap between the upper and lower ends of the vertical piece 19' and the plates A and B, and the gap can be widened or narrowed. By doing so, the minimum facing distance can be easily changed.
逆に、両板材A,Bの対向間隔が必要以上に引
き離されると、両可撓連結部14a,14bが直
線的に伸長するが、このとき、両可撓連結部14
a,14bから互いに内向きに突出した突片19
と対向片20とが互いに突き当ることで、両板材
A,Bの最大対向間隔を規制する(第6図)。 On the other hand, if the opposing distance between the plates A and B is separated more than necessary, the flexible connecting parts 14a and 14b will extend linearly.
Projecting pieces 19 projecting inward from each other from a and 14b
By abutting against each other and the facing piece 20, the maximum facing distance between the two plates A and B is regulated (FIG. 6).
これにより、両可撓連結部14a,14bが必
要以上に伸長して塑性変形するのが未然に防止で
きる。尚、両板材A,Bの最大対向間隔は、突片
19の縦片19′の外側面と対向片20の先端と

で、しかも、該隙間を広狭することで最大対向間
隔を容易に変更可能である。 This can prevent the flexible connecting portions 14a, 14b from elongating more than necessary and causing plastic deformation. The maximum facing distance between the plates A and B can be freely set by determining the gap between the outer surface of the vertical piece 19' of the projecting piece 19 and the tip of the facing piece 20. The maximum facing distance can be easily changed by widening or narrowing.
又、両板材A,Bの最大対向間隔を予め決定す
ることができるので、他の部品や部材(図示せ
ず)との間のクリアランスの設定も容易であり、
このクリアランスを確保してあれば、板材A,B
に予想以上の力が加わつた際にも、板材A,Bが
他の部品や部材に接触するおそれがない。 In addition, since the maximum facing distance between the plates A and B can be determined in advance, it is easy to set the clearance between them and other parts and members (not shown).
If this clearance is secured, plates A and B
Even when an unexpected force is applied to the plates, there is no risk that the plates A and B will come into contact with other parts or members.
更に、両板材A,Bの最小、最大対向間隔を規
制することで、板材A,Bの上下動の幅が規制さ
れるので、規制してないものに比べ、振動時の収
束を速くできる。 Furthermore, by regulating the minimum and maximum spacing between the plates A and B, the width of vertical movement of the plates A and B is regulated, so vibrations can be converged more quickly than when they are not regulated.
一方、振動時に両板材A,Bの間に傾きが生じ
たときにも、必要以上に傾くと、上下の支持部1
3a,13bの突起部18がリング状に屈曲して
一方の可撓連結部14aの外側面に突き当つて、
両板材A,Bが必要以上に左右一方に傾くのを阻
止する(第7図)。 On the other hand, when a tilt occurs between the two plates A and B during vibration, if the tilt is more than necessary, the upper and lower support parts 1
The protrusions 18 of 3a and 13b are bent into a ring shape and abut against the outer surface of one of the flexible connecting parts 14a,
This prevents both plates A and B from tilting to either the left or right side more than necessary (Fig. 7).
