Description

本願発明は、書架（書棚）のような棚装置（ラック）とこれを床に固定する連結金具とに関するものである。 The present invention relates to a shelf device (rack) such as a bookshelf (book shelf) and a connection fitting for fixing the same to a floor.

書架のような棚装置は、転倒防止のために床に固定することが行われている。特に、間口寸法に対して奥行き寸法が小さいと前後方向に倒れ易くなるため、前後方向に倒れることを防止する必要がある。また、転倒防止は特に地震対策として必要であり、図書館の書架のように不特定多数の人が使用する棚装置では、地震時における利用者の安全確保や書籍の散乱防止のために転倒防止手段は特に重要であると言える。 A shelf device such as a bookshelf is fixed to the floor in order to prevent falling. In particular, if the depth dimension is small with respect to the frontage dimension, it tends to fall down in the front-rear direction, so it is necessary to prevent it from falling down in the front-rear direction. In addition, prevention of falls is particularly necessary as a countermeasure against earthquakes. For shelf devices used by an unspecified number of people, such as library shelves, means to prevent falls to ensure the safety of users and prevent books from being scattered during an earthquake. Is particularly important.

棚装置の転倒防止手段として従来は、水平片と垂直片とを有するＬ形の連結金具が使用されており、水平片をアンカーで床に固定し、垂直片を棚本体にボルト（ビス）で締結している。この場合、水平片は棚本体の外側に露出させていることが殆どであるため、体裁が悪いと共に、人の足が当たって躓くおそれもあった。 Conventionally, an L-shaped connecting bracket having a horizontal piece and a vertical piece is used as a means for preventing the fall of the shelf device. The horizontal piece is fixed to the floor with an anchor, and the vertical piece is attached to the shelf body with bolts (screws). It is concluded. In this case, since the horizontal piece is mostly exposed to the outside of the shelf main body, the appearance is not good and there is a risk of hitting a person's foot.

他方、特許文献１には、下向き開口の浅い箱状ベースを有するキャビネットを床に固定するための手段として、箱状ベースの内部に隠れるレール金具（連結金具）をアンカーで床に固定し、ベースを連結金具の上面にビスで固定することが記載されている。 On the other hand, in Patent Document 1, as a means for fixing a cabinet having a box-like base having a shallow downward opening to the floor, a rail fitting (connection fitting) hidden inside the box-like base is fixed to the floor with an anchor. Is fixed to the upper surface of the connecting bracket with screws.

特開２０００−２３２２７０号公報JP 2000-232270 A

特許文献１のレール金具はキャビネットのベースの内部に隠れていて外側から視認できないため、美観が悪化したり人が躓いたりする問題は生じない。しかし、箱状ベースをレール部材に上から重ねてビスで締結するものであるため、書棚のように箱状ベースを備えていない棚装置には適用できない問題がある。また、床には凹凸や傾斜があることが多く、そこで連結金具と床との間にスペーサ板を配置して隣り合った棚装置の高さを調節したり水平度を出したりしているが、特許文献１の構成ではいったんキャビネットを設置するとレール部材の高さを変更することはできないため、床の凹凸や傾斜への対応が難しいという問題もあった。 Since the rail metal fitting of patent document 1 is hidden inside the base of a cabinet and cannot be visually recognized from the outside, the problem that aesthetics deteriorate or a person crawls does not arise. However, since the box-shaped base is overlapped on the rail member from above and fastened with screws, there is a problem that it cannot be applied to a shelf apparatus that does not have a box-shaped base such as a bookcase. In addition, the floor often has irregularities and slopes, and a spacer plate is placed between the connecting bracket and the floor to adjust the height of the adjacent shelf devices and to increase the level. In the configuration of Patent Document 1, once the cabinet is installed, the height of the rail member cannot be changed, so that there is a problem that it is difficult to cope with unevenness and inclination of the floor.

棚本体はこのような現状に鑑み成されたものであり、棚装置用の改良された床固定構造を提供することを目的とするものである。 The shelf main body is made in view of such a current situation, and an object thereof is to provide an improved floor fixing structure for a shelf apparatus.

連結金具は請求項５で特定されている。すなわち、この連結金具は請求項２〜４のうちのいずれかに記載した連結金具を対象にしており、棚本体におけるサイド支持体の下方において前後方向に延びる細長いベース板と、前記ベースの少なくとも前後両端寄り部位に突設した起立部とを有しており、前記ベース板のうち、前記起立部よりも前後内側の少なくとも２カ所の部位に、前記アンカーが貫通する締結穴を設け、前記起立部には、前記サイド支持体を固定するボルトがねじ込まれる雌ねじ穴を空けている。
請求項６の発明は、請求項１の構成に加えて、「前記サイド支持体の下端部には、左右の側板を有しかつ前記連結金具が下方から入り込む下向き開口部が形成されており、前記下向き開口部が、当該下向き開口部の内部に位置した前記連結金具に前記ねじで固定されている」、という構成を含んでいる。
請求項７の発明は、請求項６において、前記連結金具は、前記アンカーで床に固定されるベース板と、前記ベース板から上向きに突出して前記サイド支持体の下向き開口部に入り込む起立部とを有しており、前記サイド支持体における下向き開口部の側板が前記ねじで前記連結金具の起立部に締結されている。
請求項８の発明は、請求項２と同じほぼ同様の前提の構成において、前記サイド支持体の下端部には、左右の側板を有する下向き開口部が形成されており、前記下向き開口部と前記連結金具とを左右に重ねて両者を前記ねじで固定している。 The connecting fitting is specified in claim 5. That is, this connection fitting is intended for the connection fitting according to any one of claims 2 to 4, and is an elongated base plate extending in the front-rear direction below the side support in the shelf body, and at least front and rear of the base has a standing portion projecting from the both ends toward the site, of the base plate, the portion of the at least two locations of the inner front and rear than the standing part, provided with a fastening hole in which the anchor penetrates, the standing portion Is provided with a female screw hole into which a bolt for fixing the side support is screwed.
In addition to the configuration of claim 1, the invention of claim 6 has a structure in which “the lower end portion of the side support has left and right side plates and a downward opening into which the connecting fitting enters from below is formed. The downward opening is fixed to the connection fitting located inside the downward opening with the screw.
The invention of claim 7 is the invention according to claim 6, wherein the connection fitting includes a base plate fixed to the floor by the anchor, and an upright portion protruding upward from the base plate and entering a downward opening of the side support. The side plate of the downward opening in the side support is fastened to the upright portion of the coupling fitting with the screw.
According to an eighth aspect of the present invention, in the configuration based on substantially the same assumption as in the second aspect, a downward opening having left and right side plates is formed at a lower end portion of the side support, and the downward opening and the The connecting metal fittings are overlapped on the left and right, and both are fixed with the screws.

本願各発明では、連結金具は全体が棚本体の下方に配置されているので、連結金具が人目に触れて体裁が悪くなったり人が連結金具に躓いたりすることはない。また、棚本体のサイド支持体は横向き姿勢のねじで連結金具に固定されているため、例えば、連結金具と床との間にスペーサ板を差し込みながら高さや姿勢を調整することも簡単に行える。 In the present inventions, the entire connection fitting is because it is disposed below the shelf body, is not a person or appearance becomes poor connection fitting touch the person is or stumbled on connecting fitting. Further, since the side support of the shelf main body is fixed to the connecting bracket with a laterally oriented screw, for example , the height and posture can be easily adjusted while inserting a spacer plate between the connecting bracket and the floor.

請求項２，７の構成を採用すると、連結金具の起立部もサイド支持体の内部に隠れるため、連結金具が人目に触れることをより的確に防止して美観の向上を確実に実現できる。同様に、ねじは棚本体の内側からねじ込むものであるため、ねじの頭が人目に触れることはなく、この面においても体裁がよい。 If the structure of Claim 2 and 7 is employ | adopted, since the standing part of a connection metal fitting is also hidden inside a side support body, it can prevent more accurately that a connection metal fitting touches a human eye, and can implement | achieve the improvement of an aesthetics reliably. Similarly, since the screw is screwed from the inside of the shelf main body, the head of the screw is not touched by human eyes, and the appearance is good also in this aspect.

既述のとおり、書架のような棚装置は間口寸法に対して奥行き寸法が小さいため、例えば地震時には前後方向に転倒し易くなる。この場合、棚本体にこれを前倒しする外力が作用すると、後部のアンカーに対して引き抜きの力が作用し、棚本体を後ろに倒そうとする外力が作用すると、前部のアンカーに対して引き抜きの力が作用することになるが、棚本体が前倒れしようとする場合は、棚本体の前倒れ支点から後部アンカーまでの距離（支持スパン）が大きいほど転倒しにくくなり、棚本体が後ろ倒れしようとする場合は、棚本体の後ろ倒れ支点から後部アンカーまでの距離が大きいほど転倒しにくくなる。 As described above, a shelf device such as a bookshelf has a small depth dimension with respect to a frontage dimension, and thus, for example, during an earthquake, the shelf apparatus easily falls in the front-rear direction. In this case, when an external force that moves the shelf body forward acts on the shelf body, a pulling force acts on the rear anchor, and when an external force that attempts to tilt the shelf body backward acts on the shelf body, the pulling is performed on the front anchor. However, if the shelf body is going to fall forward, the greater the distance from the fulcrum fulcrum of the shelf body to the rear anchor (support span), the more difficult it will fall, and the shelf body will fall back When trying to do so, the greater the distance from the back tilting fulcrum of the shelf body to the rear anchor, the more difficult it is to fall.

そして、請求項３の発明では、連結金具の前と後ろにアジャスタボルトがあってこれが接地しているため、棚本体はアジャスタボルトを支点にして転倒しようとすることになり、アジャスタボルトを備えていない場合に比べて支持スパンが長くなる（前後転倒に対する安定性が高くなる。）。その結果、高さ調節機能を損なうことなく転倒防止機能を向上できる。 In the invention of claim 3 , since there are adjuster bolts in front of and behind the connecting metal fittings and these are grounded, the shelf body is going to fall with the adjuster bolt as a fulcrum, and is equipped with the adjuster bolt. The support span is longer than when it is not present (the stability against overturning is increased). As a result, the fall prevention function can be improved without impairing the height adjustment function.

また、例えば棚本体が前倒れしようすると連結金具の後部が浮こうとするが、請求項３ではアジャスタボルトとアンカーとが略一直線状に並んでいるため、アジャスタボルトが床に突っ張って連結金具の浮きがしっかり阻止される。その結果、転倒防止機能をより一層向上させることができる。 Further, for example, when the shelf body is tilted forward, the rear part of the connecting bracket tends to float. However, in claim 3 , the adjuster bolt and the anchor are arranged substantially in a straight line. Lifting is firmly prevented. As a result, the fall prevention function can be further improved.

床の凹凸や傾斜に対応して連結金具の高さを調節するためのスペーサ板は様々の形態を採用できるが、請求項４の形態を採用すると、スペーサ板はねじで離反不能に保持された状態でアンカーで床に押さえ固定されているため安定性に優れており、しかも、止めねじを緩めることで、スペーサ板は連結金具と床との間に挿脱自在であるため、棚装置を所定位置にセットして連結金具をアンカーに嵌め込んだ状態のままで、スペーサ板を挿入したり取り外したりすることができる。 The spacer plate for adjusting the height of the connecting metal fitting according to the unevenness and the inclination of the floor can adopt various forms, but when the form of claim 4 is adopted, the spacer plate is held in an inseparable manner by screws. It is excellent in stability because it is pressed and fixed to the floor with an anchor in the state, and the spacer plate can be inserted and removed between the connecting bracket and the floor by loosening the set screw. the connecting fitting is set to a position in the state is fitted to the anchor, or can remove or insert the spacer plate.

すなわち、連結金具をアンカーから抜き外すことなく、スペーサ板を連結金具と床との間に挿脱できるのであり、このため、床の状態に合わせて高さ調節しながら棚装置を設置していく作業を簡単に行える。特に、請求項３のようにアジャスタボルトを設けていると、アジャスタボルトで所定の高さに保持してから連結金具と床との間の隙間にスペーサ板を挿入することができるため、特に好適である。 In other words, the spacer plate can be inserted / removed between the connecting bracket and the floor without removing the connecting bracket from the anchor. For this reason , the shelf apparatus is installed while adjusting the height according to the state of the floor. Work can be done easily. Particularly, when the adjuster bolt is provided as in the third aspect , the spacer plate can be inserted into the gap between the connecting metal fitting and the floor after being held at a predetermined height by the adjuster bolt. It is.

次に、本願発明の実施形態を図面に基づいて説明する。本実施形態は、書架（書棚）に適用している。本願発明では、方向を特定するため「前後」「左右」の文言を使用するが、書架の奥行き方向が「前後」の方向であり、間口方向が「左右」の方向である。 Next, an embodiment of the present invention will be described with reference to the drawings. This embodiment is applied to the shelves (bookshelf). In the present invention, but use the word "longitudinal", "lateral" to identify the direction, a direction of the depth direction of the shelves is "longitudinal", frontage direction is the direction of "horizontal".

(1).概略
まず、図１〜図３に基づいて概略を説明する。書架は、板状の外観を呈する左右のサイド支持体１と、これら左右のサイド支持体１を連結する背板２、及び左右のサイド支持体１と背板２との間の物品収納部に配置した複数枚の棚板３とを有しており、これらサイド支持体１と背板２と棚板３とで棚本体４が構成されている。図１〜４の実施形態は、背板２を挟んだ前後両側に収納部を有する両面仕様タイプであり、このため、背板２は左右サイド支持体１の前後中間部に連結されている。なお、サイド支持体１は、側パネル又は側枠体と呼ぶことも可能である。 (1). Outline First, an outline will be described with reference to FIGS. The bookshelf is provided on the left and right side supports 1 that have a plate-like appearance, the back plate 2 that connects the left and right side supports 1, and the article storage unit between the left and right side supports 1 and the back plate 2. It has a plurality of shelf plates 3 arranged shelf body 4 is constituted by the this Rasa id support 1 and the back plate 2 and the shelf plate 3. The embodiment shown in FIGS. 1 to 4 is a double-sided specification type having storage portions on both front and rear sides sandwiching the back plate 2, and for this reason , the back plate 2 is connected to the front and rear intermediate portions of the left and right side supports 1. The side support 1 can also be called a side panel or a side frame.

書架を左右に連結された多連式と成す場合は、隣り合った書架でサイド支持体１が共用されている。従って、多数枚のサイド支持体１の群のうち左右最端のものをエンド支持体と呼び、エンド支持体の間に位置したものを中間支持体と呼ぶことも可能である。 In the case where the bookshelf is a multiple type connected to the left and right, the side supports 1 are shared by adjacent bookshelves. Therefore, it is also possible to call the left and rightmost end group of the group of side support bodies 1 as an end support body and the one located between the end support bodies as an intermediate support body.

図１（Ｂ）や図２に示すように、サイド支持体１は、大まかには木質系の芯板５の両面に金属製化粧板（表面板）６を張った構造になっており、前端と後端との内部には上下長手で前後外側に開口したコの字形のフロント縦補強枠７を配置し、前後中間部には、１本の第１センター補強枠８と、その前後両側に配置した第２センター補強枠９とを配置している。 As shown in FIG. 1 (B) and FIG. 2, the side support 1 has a structure in which a metal decorative plate (surface plate) 6 is stretched on both sides of a wood-based core plate 5 and the front end. the inside of the rear end arranged front vertical reinforcing frame 7 of shaped opening was co outer back and forth up and down the longitudinal, in the front and rear intermediate portion, the first center reinforcing frame 8 of one, on both sides before and after The arranged second center reinforcing frame 9 is arranged.

化粧板６の前後両端部は、内向きに折り返されている。サイド支持体１の上端部には前後長手のアッパー補強枠を設けているが、本願発明との関連はないので説明は省略する。サイド支持体１の化粧板６には、棚板３を支持するブラケット（図示せず）が嵌まる係止穴１０を多段に設けている。係止穴１０は、バーリング加工によって筒状に形成されている。係止穴１０は、フロント補強枠８と芯板４との間、及び、第２センター補強枠９と芯板４との間の部位に形成している。なお、エンドに位置したサイド支持体１については、収納部に面した片側の化粧板６のみに係止穴１０を設けている。 Front and rear end portions of the veneer 6 is folded back inwardly. Although an upper and lower longitudinal reinforcing frame is provided at the upper end of the side support 1, description thereof is omitted because it is not related to the present invention. The decorative plate 6 of the side support 1 is provided with multi-stage locking holes 10 into which brackets (not shown) for supporting the shelf plate 3 are fitted. Locking hole 10 is formed in a cylindrical shape by burring. The locking holes 10 are formed between the front reinforcing frame 8 and the core plate 4 and at portions between the second center reinforcing frame 9 and the core plate 4. In addition, about the side support body 1 located in the end, the latching hole 10 is provided only in the decorative board 6 of the one side which faced the accommodating part.

サイド支持体１の下端部のうち前部と後部とには、それぞれ前後方向に長い下補強枠１１を配置している。下補強枠１１は、左右の側板１１ａ，１１ｂを有する正面視下向き開口コの字形の形態であり、表裏の化粧板６で左右から挟まれている（下補強枠１１は化粧板６に接着されている。）。この下補強枠１１により、請求項に記載した下向き開口部が構成されている。なお、下補強枠１１を前後に分離せずに、一連に延びる形態と成すことも可能である。すなわち、サイド支持体１の下端部の全体を下向き開口部と成すことも可能である。 A lower reinforcing frame 11 that is long in the front-rear direction is disposed at the front and rear of the lower end of the side support 1. The lower reinforcing frame 11 has a U-shaped configuration with the left and right side plates 11a and 11b facing downward, and is sandwiched from the left and right by the front and back decorative plates 6 (the lower reinforcing frame 11 is bonded to the decorative plate 6). ing.). The lower reinforcing frame 11 constitutes the downward opening described in the claims. Note that the lower reinforcing frame 11 may be configured to extend in series without being separated forward and backward. In other words, the entire lower end of the side support 1 can be formed as a downward opening.

下補強枠１１の前端部にはフロント縦補強枠７が上から当接しており、両者は溶接によって一体化されている。また、下補強枠１１の前端部の上底面には四角形の支持ナット１２が溶接されており、支持ナット１２に下方からアジャスタボルト１３がねじ込まれている。アジャスタボルト１３は、下補強枠１１を貫通してフロント縦補強枠７に入り込んでいる。 A front vertical reinforcing frame 7 is in contact with the front end portion of the lower reinforcing frame 11 from above, and both are integrated by welding. A square support nut 12 is welded to the upper bottom surface of the front end portion of the lower reinforcing frame 11, and an adjuster bolt 13 is screwed into the support nut 12 from below. The adjuster bolt 13 penetrates the lower reinforcing frame 11 and enters the front vertical reinforcing frame 7.

図２（Ｂ）に示すように、背板２も芯板１４に化粧板１５を張った基本構造であり、左右両側部や上端部には補強枠１６を設けている。背板２は、連結金具（図示せず）を使用してサイド支持体１に連結されている。敢えて述べるまでもないが、サイド支持体１や背板２の構造は任意に設定できる。 As shown in FIG. 2 (B), the back plate 2 also has a basic structure in which a decorative plate 15 is stretched on a core plate 14, and reinforcing frames 16 are provided on the left and right sides and the upper end. The back plate 2 is connected to the side support 1 using a connection fitting (not shown). Needless to say, the structures of the side support 1 and the back plate 2 can be arbitrarily set.

(2).床への固定構造
棚本体４は、サイド支持体１の下に配置した連結金具１８によって床Ｆに固定されている。この点を図４も参照して説明する。連結金具１８は、アンカー１９で床Ｆに固定される前後長手のベース板２０と、ベース板２０の前後両端部に上向き突設した起立部２１とで構成されている。ベース板１０と起立部２１とはいずれも厚い金属板（鋼板）から成っており、両者は溶接によって一体化されている。 (2). Fixing structure to the floor The shelf body 4 is fixed to the floor F by a connecting metal fitting 18 disposed under the side support 1. This point will be described with reference to FIG. The connecting fitting 18 is composed of a longitudinal base plate 20 that is fixed to the floor F by an anchor 19, and standing portions 21 that protrude upward at both front and rear ends of the base plate 20. Both the base plate 10 and the upright portion 21 are made of a thick metal plate (steel plate), and both are integrated by welding.

起立部２１は、サイド支持体１を構成する下補強枠１１の内部に入り込んでおり、下補強枠１１の一方の側板１１ａが、横向き姿勢のボルト２２で起立部２１に締結されている。このため、下補強枠１１の側板１１ａ，１１ｂと化粧板６とにボルト挿通穴２３が空いていると共に、起立部２１には雌ねじ穴２４が形成されている。ボルト挿通穴２３は多少の高さ調節を可能にするため上下に長い長穴になっている。また、ボルト２２には通常よりも大径の座金２５が嵌まっている。ボルト２２はねじの一例である。 Upright portion 21 is penetrated into the inside of the lower reinforcing frame 11 constituting the side support 1, one side plate 11a of the lower reinforcing frame 11 is fastened to the upright portion 21 with a bolt 22 of the horizontal position. For this reason, the bolt insertion hole 23 is vacant in the side plates 11 a and 11 b of the lower reinforcing frame 11 and the decorative plate 6, and the female screw hole 24 is formed in the standing portion 21. The bolt insertion hole 23 is a long hole that is long in the vertical direction in order to allow some height adjustment. The bolt 22 is fitted with a washer 25 having a diameter larger than usual. The bolt 22 is an example of a screw.

図４（Ｂ）に示すように、ボルト２２は、左右サイド支持体１の間の部位（棚本体１の内部）から起立部２１にねじ込まれている。従って、ボルト２２の頭が棚本体１の外側に露出することはない。また、ベース板２０は、左右中間部がアンカー１９で固定されるようになっている。このため、連結金具１８は、起立部２１が右にずれた状態でも左にずれた状態でも、サイド支持体１を締結することができる。 As shown in FIG. 4B, the bolt 22 is screwed into the upright portion 21 from a portion between the left and right side support bodies 1 (inside the shelf main body 1) . Accordingly, the head of the bolt 22 is not exposed to the outside of the shelf body 1. The base plate 20 is fixed at the left and right intermediate portions by anchors 19. For this reason, the connecting fitting 18 can fasten the side support 1 even when the upright portion 21 is shifted to the right or to the left.

エンドに位置したサイド支持体１を除いた中間位置のサイド支持体１については、下補強枠１１のいずれの側板１１ａ，１１ｂを固定してもボルト２２の頭は外側から見えないので、起立部２１は右にずれた状態でも左にずれた状態でもよいが、施工に際しては、起立部２１が右にずれた状態か左にずれた状態かのいずれかを基準にして全体を揃え、１つのエンドの箇所においてのみ逆に配置するのが良いと言える。なお、連結金具１８は、前後向きを変えると起立部２１が左にずれた状態と右にずれた状態とに変わるため、１種類のみで足りる。 For the side support 1 in the middle position excluding the side support 1 located at the end, the head of the bolt 22 cannot be seen from the outside even if any of the side plates 11a and 11b of the lower reinforcing frame 11 is fixed. 21 may be shifted to the right or to the left, but in the construction, the whole is aligned on the basis of either the standing portion 21 being shifted to the right or the left. It can be said that it is better to arrange them only at the ends. It should be noted that only one type of connection fitting 18 is required because the upright portion 21 is shifted to the left and to the right when the front-rear direction is changed.

連結金具１８のベース板２０は前後アジャスタボルト１３の近くまで延びており、起立部２１の内側（ベース板１９の前後中間部寄りの側）には、アンカー１９に嵌まる締結穴２５が空いている。締結穴２５は前後対称位置に形成されており、アンカー１９の施工誤差を吸収するため左右長手の長穴になっている。図１（Ｂ）に明示するように、アンカー１９（及び締結穴２５）とアジャスタボルト１３とは、ベース板２０及びサイド支持体１の前後長手中心線Ｏ上に位置している。すなわち、前後のアジャスタボルト１３と前後アンカー１９及び締結穴２５は、前後方向に一直線状に並んでいる。 The base plate 20 of the connection fitting 18 extends to the vicinity of the front and rear adjuster bolts 13, and a fastening hole 25 that fits into the anchor 19 is provided inside the upright portion 21 (on the side closer to the front and rear intermediate portion of the base plate 19). Yes. The fastening hole 25 is formed at a symmetrical position in the front-rear direction, and is an elongated hole in the left-right longitudinal direction in order to absorb construction errors of the anchor 19. As clearly shown in FIG. 1B, the anchor 19 (and the fastening hole 25) and the adjuster bolt 13 are positioned on the longitudinal center line O of the base plate 20 and the side support 1. That is, the front and rear adjuster bolts 13, the front and rear anchors 19, and the fastening holes 25 are aligned in the front-rear direction.

アンカー１９は、下穴に挿入してから芯棒を打ち込み又はねじ込む拡張式のタイプであり、床上に露出した雄ねじ部にナット２６をねじ込むことにより、サイド支持体１が床Ｆに固定される。敢えて述べるまでもないが、アンカー１９は拡張式である必然性はなく、ねじ込み式のものやケミカルアンカーなども使用できる。 The anchor 19 is an expansion type in which the core rod is driven or screwed in after being inserted into the pilot hole, and the side support 1 is fixed to the floor F by screwing the nut 26 into the male screw portion exposed on the floor. Needless to say, the anchor 19 is not necessarily an expandable type, and a screw-in type or a chemical anchor can be used.

ベース板２０のうち締結穴２５よりも前後内側の部位には、スペーサ板２７を取り付けるための止めねじ（ボルト）２８がねじ込まれる雌ねじ穴２９を空けている。雌ねじ穴２９も前後対称の位置に空けられている。スペーサ板２７の一端部には、止めねじ２９が貫通する抜け止め穴３０を空けており、また、前後中間部には、アンカー１９に横から嵌脱する逃がし溝３１が長手一側縁に切り開き形成されている。 The site before and after the inside than the fastening hole 25 of the base plate 20, a set screw (bolt) 28 for attaching the spacer plate 27 is spaced internally threaded hole 29 to be screwed. The female screw hole 29 is also formed at a symmetrical position. One end portion of the spacer plate 27 is provided with a retaining hole 30 through which a set screw 29 penetrates, and a relief groove 31 that fits and detaches from the side of the anchor 19 is cut open at one side edge in the longitudinal direction. Is formed.

図５では、スペーサ板２７を使用して高さ調節している状態を示している（この図５に示す書架は片面仕様である。）。敢えて述べるまでもないが、スペーサ板２７は、下補強枠１１の側板１１ａ，１１ｂに空けたボルト挿通穴２３によっては高さ調節できないときに使用される。スペーサ板２７は、ベース板２０の前後両端まで延びている。 FIG. 5 shows a state in which the height is adjusted using the spacer plate 27 (the book rack shown in FIG. 5 is a single-sided specification). Needless to say, the spacer plate 27 is used when the height cannot be adjusted by the bolt insertion holes 23 formed in the side plates 11 a and 11 b of the lower reinforcing frame 11. The spacer plate 27 extends to the front and rear ends of the base plate 20.

スペーサ板２７を使用した固定工程では、具体的には、アジャスタボルト１３で高さ調節して、ベース板２０と床Ｆとの間に空いた隙間にスペーサ板２７を必要枚数挿入し、次いで、ベース板２０の雌ねじ穴２９にねじ込んだ止めねじ２８をスペーサ板２７の抜け止め穴３０に挿入すると共に、逃がし溝３１をアンカー１９に横から嵌め込み、次いで、アジャスタボルト１３を上向きにねじ込むことで当該アジャスタボルト１３の床Ｆへの突っ張りをいったん解除して、次いで、ナット２６をアンカー１９にねじ込んでスペーサ板２７を床に押さえ固定し、それから再びアジャスタボルト１３を下向きにねじ戻して床Ｆに突っ張らせる、という手順が採られる。スペーサ板２７の要否や使用する場合の枚数は、各アンカー１９の箇所で判断したらよい。 In the fixing process using the spacer plate 27, specifically, the height is adjusted with the adjuster bolt 13, and the required number of spacer plates 27 are inserted into the gap formed between the base plate 20 and the floor F. The set screw 28 screwed into the female screw hole 29 of the base plate 20 is inserted into the retaining hole 30 of the spacer plate 27, the relief groove 31 is fitted into the anchor 19 from the side, and then the adjuster bolt 13 is screwed upward. The tension of the adjuster bolt 13 to the floor F is once released, and then the nut 26 is screwed into the anchor 19 to fix the spacer plate 27 to the floor, and then the adjuster bolt 13 is again screwed downward and pulled to the floor F. The procedure is taken. Number in the case of a necessity and use of the spacer plate 27, can it judged at the location of each anchor 19.

(3).まとめ
既に述べたように、連結金具１８はサイド支持体１の下方に隠れているので、人目に触れることは殆どない。このため体裁が良いと共に、連結金具１８に人の靴が当たって躓くといった問題は全くない。また、棚板３は着脱自在であり、棚本体４の収納部を広く開放できるため、ボルト２２を棚本体４の収納部からねじ込むことに全く支障はない。従って、設置作業の容易性を損なうことなく、美観の悪化を防止できると共に躓きも防止できるのである。 (3). Conclusion As already mentioned, the coupling fitting 18 is hidden below the side support 1, hardly touching the person. For this reason, the appearance is good and there is no problem that a person's shoes hit the connecting fitting 18 at all. Moreover, since the shelf board 3 is detachable and the storage part of the shelf main body 4 can be opened widely, there is no problem in screwing the bolt 22 from the storage part of the shelf main body 4. Therefore, it is possible to prevent the appearance from deteriorating and to prevent whispering without impairing the ease of installation work.

図７に示すように、地震等によって例えば棚本体４を前倒しする外力Ｇが作用すると、棚本体４は一点鎖線で示すように前倒れする状態になり、これに伴い、後部のアンカー１９に引き抜きの作用（モーメント）がかかる。この場合、後部のアンカー１９に作用する引き抜き力Ｇ′は、棚本体４の前傾支点から後部のアンカー１９までの距離スパンに反比例するが、アジャスタボルト１３が存在しない場合はスパンがＬ１であるのに対して、アジャスタボルト１３が存在するとスパンはＬ２と大きくなる。このため、アンカー１９に作用する引き抜き力Ｇ′を抑制して固定強度を向上できる。 As shown in FIG. 7, for example, when an external force G that pushes the shelf body 4 forward is applied due to an earthquake or the like, the shelf body 4 falls forward as shown by the alternate long and short dash line, and accordingly, the rear anchor 19 is pulled out. The action (moment) is applied. In this case, withdrawal force G 'is acting on the rear of the anchor 19, is inversely proportional to the distance span from the previous傾支point of the shelf body 4 to the rear of the anchor 19, when the adjuster bolt 13 is not present span is L1 On the other hand, when the adjuster bolt 13 is present, the span is increased to L2. For this reason, the pulling force G ′ acting on the anchor 19 can be suppressed and the fixing strength can be improved.

また、棚本体４に前倒ししようとする外力Ｆが作用すると、連結金具１８は後部のボルト２２の箇所で引き上げられる状態になり、従って、後部のアンカー１９を引き抜こうする力Ｇ′の大きさは、棚本体４の前傾支点から後部のボルト２２までの距離に反比例する。そして、本実施形態ではアジャスタボルト１３が傾動支点になるため、棚本体４の前傾支点から後部のボルト２２までの距離は、アジャスタボルト１３を備えていない場合のＬ３よりも大きい寸法であるＬ４になっており、このため、アンカー１９に作用する引き抜き力そのものも小さくなる。 Further, when the external force F to be moved forward is applied to the shelf body 4, the connecting bracket 18 is pulled up at the position of the rear bolt 22. Therefore, the magnitude of the force G ′ for pulling out the rear anchor 19 is as follows. It is inversely proportional to the distance from the forward tilt fulcrum of the shelf body 4 to the rear bolt 22. Since the A Jasutaboruto 13 in this embodiment is the tilting fulcrum, the distance from the front傾支point of the shelf body 4 to the rear of the bolt 22 is a size larger than L3 when not provided with the adjuster bolt 13 Therefore, the pulling force acting on the anchor 19 itself is also reduced.

このように、本実施形態では、棚本体４に、これを前後いずれかに転倒させようとする外力が作用した場合、棚本体４の支持スパンと連結金具１８の支持スパンとの両方をできるだけ大きくして、高い安定性を確保できるのである。また、アジャスタボルト１３とアンカー１９とが左右にずれていると、アジャスタボルト１３の突っ張り作用が弱くなるが、本実施形態のようにアジャスタボルト１３とアンカー１９とを略一直線状に配置すると、アジャスタボルト１３でしっかりと突っ張ってアンカー１９の抜けを阻止する状態になるため、安定性の向上に一層優れている。 Thus, in the present embodiment, the shelf body 4, when an external force that attempts to overturn it either before or after is applied, as large as possible both the support span of the supporting span the connecting fitting 18 of the shelf body 4 Thus, high stability can be secured. Further, if the adjuster bolt 13 and the anchor 19 are shifted from side to side, the tensioning action of the adjuster bolt 13 is weakened. Since the bolt 13 is pulled firmly to prevent the anchor 19 from coming off, the stability is further improved.

本願発明は、上記の実施形態の他にも様々に具体化できる。例えば、棚装置を構成するサイド支持体は必ずしも板状（パネル状）である必要はなく、前後の支柱を横桟で繋いだ枠組方式としたり、全体をスチール製のパネル構造とするといったことも可能である。書架以外の各種の棚装置に適用できることも勿論である。連結金具は、１枚の金属板をＬ形に曲げ加工した形態であってもよい。棚本体のサイド支持体を連結金具に固定する手段としては、サイド支持体の下端部にナットを溶接等で固定し、連結金具に挿通したボルトをこのナットにねじ込むといったことも可能である。 (4). Others present invention can be in addition to various concrete than the above embodiment. For example , the side supports that make up the shelf device do not necessarily have to be plate-shaped (panel-shaped), but may be a frame system in which the front and rear columns are connected by horizontal rails, or the entire structure may be a steel panel structure. Is possible. Of course, the present invention can be applied to various kinds of shelf devices other than the bookshelf. Connecting fitting may be processed form bending a metal plate into an L-shaped. As a means for fixing the side support of the shelf body to the connection fitting, a nut may be fixed to the lower end portion of the side support by welding or the like, and a bolt inserted through the connection fitting may be screwed into the nut.
