Description

本発明は,電化製品の組み立てなどに使用される雄ネジを保護するネジカバーに関し,特に,そのネジカバーの装着を簡単にするための技術に関するものである。   The present invention relates to a screw cover for protecting a male screw used for assembling an electric appliance, and more particularly to a technique for simplifying the mounting of the screw cover.

一般に,電化製品などの機器を組み立てる際,部品の接合に金属製のネジが用いられる。このネジは,その機器からの熱伝導によって高温になるおそれがある。そのため,人が容易に触れることができないように対策を施すことが望ましい。例えば,機器の筐体の外部から雄ネジを螺着した際にその雄ネジの頭部が筐体に埋没するように,雄ネジの螺着部の深さを十分に確保しておくことが考えられる。但し,この場合には,その深さを確保するために筐体を厚くする必要があり,機器の薄型化が阻害される。
一方,特許文献1には,ネジの頭部が露出しないようにネジカバーを装着する構成が開示されている。これにより,機器の薄型化を阻害することなく,人が容易にネジに触れることができない構造を実現することができる。ここで,図8を用いて,前記特許文献1に開示されたネジカバーの取り付けを伴うネジの螺着作業について説明する。
まず,図8(a)に示すように,雄ネジ100の胴部101をネジカバー200に嵌挿させる。次に,図8(b)に示すように,雄ネジ100を筐体300に設けられた雌ネジ部301に螺着する。その後,図8(c)に示すように,雄ネジ100の頭部102を覆うようにネジカバー200をヒンジ部201で折り曲げる。
特開平8−320012号公報
Generally, when assembling equipment such as electrical appliances, metal screws are used to join parts. These screws can become hot due to heat conduction from the equipment. Therefore, it is desirable to take measures to prevent people from touching easily. For example, when a male screw is screwed from the outside of the device casing, the depth of the screwed portion of the male screw must be sufficiently secured so that the head of the male screw is buried in the housing. Conceivable. However, in this case, it is necessary to increase the thickness of the casing in order to secure the depth, and this makes it difficult to reduce the thickness of the device.
On the other hand, Patent Document 1 discloses a configuration in which a screw cover is mounted so that the screw head is not exposed. As a result, it is possible to realize a structure in which a person cannot easily touch a screw without hindering thinning of the device. Here, with reference to FIG. 8, the screwing operation involving the attachment of the screw cover disclosed in Patent Document 1 will be described.
First, as shown in FIG. 8A, the body 101 of the male screw 100 is inserted into the screw cover 200. Next, as shown in FIG. 8B, the male screw 100 is screwed into the female screw portion 301 provided in the housing 300. Thereafter, as shown in FIG. 8C, the screw cover 200 is bent by the hinge portion 201 so as to cover the head 102 of the male screw 100.
Japanese Patent Laid-Open No. 8-320012

しかしながら,前記特許文献1に開示された構成では,前述したようにネジカバー200の装着作業,雄ネジ100の螺着作業,及びネジカバー200の折曲作業の少なくとも3段階の作業が必要になる。機器の組み立ての作業効率を向上させるためにも,ネジの螺着作業はできるだけ簡単であることが望ましい。
従って,本発明は上記事情に鑑みてなされたものであり,その目的とするところは,雄ネジの頭部をカバーする構造をできるだけ簡単な作業で実現することのできるネジカバーを提供することにある。
However, in the configuration disclosed in Patent Document 1, it is necessary to perform at least three steps of the screw cover 200 mounting operation, the male screw 100 screwing operation, and the screw cover 200 bending operation as described above. In order to improve the efficiency of assembling the equipment, it is desirable that the screwing operation is as simple as possible.
Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a screw cover capable of realizing a structure for covering the head of a male screw with as simple an operation as possible. .

上記目的を達成するために本発明は,雄ネジの胴部を嵌挿するための嵌挿孔を有するネジ装着部と,前記雄ネジの頭部の一部又は全部を覆うためのカバー部と,前記カバー部が前記ネジ装着部の嵌挿孔に嵌挿された前記雄ネジの頭部を覆う方向に弾性を有するように前記ネジ装着部及び前記カバー部を連結する弾性連結部とが一体形成されてなることを特徴とするネジカバーとして構成される。
この構成によれば,前記雄ネジを螺着する際に用いられる工具が該雄ネジから離間されると,前記カバー部は弾性によって前記雄ネジの頭部の一部又は全部を覆うことになる。従って,前記ネジカバーを前記雄ネジに装着した状態で該雄ネジを螺着するだけで前記雄ネジの頭部の一部又は全部をカバーする構造を実現することができる。これにより,前記雄ネジを螺着した後で,カバー部を折り曲げるための作業(例えば,特許文献1参照)を省略することができ,作業効率を向上させることができる。
また,本発明は,雄ネジの胴部を嵌挿するための嵌挿孔を有するネジ装着部と,前記雄ネジが前記ネジ装着部に嵌挿された状態で雌ネジに螺着される前は,前記雄ネジの頭部の一部又は全部を開放し,前記雄ネジが前記ネジ装着部に嵌挿された状態で雌ネジに螺着された後は,該雌ネジが設けられた被螺着部材に当該ネジカバーが接触することにより前記雄ネジの頭部の一部又は全部を覆う方向に変形するカバー部とが一体形成されてなることを特徴とするネジカバーとして構成されてもよい。
この構成によっても,前記ネジカバーを前記雄ネジに装着した状態で,該雄ネジを前記雌ネジに螺着するだけで,前記ネジカバーのカバー部が前記雄ネジの頭部の一部又は全部を覆うことになり,作業効率を向上させることができる。
ところで,前記カバー部は,前記雄ネジの頭部の一部又は全部を覆うための複数のカバー片を有するものであってもかまわない。
特に,複数の前記カバー片に,螺着された後の前記雄ネジの頭部の中心部を開放する切り欠きを形成しておくことが望ましい。これにより,前記雌ネジに螺着した前記雄ネジを取り外す際,該雄ネジの頭部の中心部に工具を当てやすくなる。
In order to achieve the above object, the present invention provides a screw mounting portion having an insertion hole for inserting a body portion of a male screw, and a cover portion for covering a part or all of the head portion of the male screw. The screw mounting portion and the elastic connecting portion for connecting the cover portion are integrated so that the cover portion has elasticity in a direction to cover the head of the male screw inserted into the insertion hole of the screw mounting portion. The screw cover is characterized by being formed.
According to this configuration, when the tool used for screwing the male screw is separated from the male screw, the cover portion elastically covers part or all of the head of the male screw. . Therefore, it is possible to realize a structure that covers a part or all of the head of the male screw by simply screwing the male screw in a state where the screw cover is attached to the male screw. Thus, after the male screw is screwed, an operation for bending the cover portion (see, for example, Patent Document 1) can be omitted, and work efficiency can be improved.
In addition, the present invention provides a screw mounting portion having a fitting insertion hole for fitting a body portion of a male screw, and before the male screw is screwed into the female screw in a state of being inserted into the screw mounting portion. After part or all of the head of the male screw is opened and the male screw is screwed onto the female screw in a state of being inserted into the screw mounting portion, the male screw is provided with the female screw. The screw cover may be configured integrally with a cover portion that deforms in a direction to cover a part or all of the head of the male screw when the screw cover comes into contact with the screw member.
Even in this configuration, the cover portion of the screw cover covers a part or all of the head of the male screw simply by screwing the male screw into the female screw with the screw cover attached to the male screw. As a result, work efficiency can be improved.
By the way, the cover part may have a plurality of cover pieces for covering part or all of the head of the male screw.
In particular, it is desirable to form notches that open the center of the head of the male screw after being screwed to the plurality of cover pieces. This makes it easier to apply a tool to the center of the head of the male screw when removing the male screw screwed on the female screw.

本発明によれば,前記ネジカバーを前記雄ネジに装着した状態で該雄ネジを螺着するだけで前記雄ネジの頭部の一部又は全部をカバーする構造を実現することができる。これにより,前記雄ネジを螺着した後で,カバー部を折り曲げるための作業(例えば,特許文献1参照)を省略することができ,作業効率を向上させることができる。   According to the present invention, it is possible to realize a structure that covers a part or all of the head of the male screw by simply screwing the male screw in a state where the screw cover is attached to the male screw. Thus, after the male screw is screwed, an operation for bending the cover portion (see, for example, Patent Document 1) can be omitted, and work efficiency can be improved.

(First embodiment)
First, the screw cover X1 according to the first embodiment of the present invention will be described with reference to FIG. Here, FIGS. 1A, 1B and 1C are a side view, a top view and an external view of the screw cover X1, and FIGS. 1D, 1E and 1F are the male screw 1 of the screw cover X1. FIG. 1 (g) and FIG. 1 (h) are a side view, a top view, and FIG. 1 showing a state in which the male screw 1 to which the screw cover X1 is attached is being screwed. (I), (j), (k) is a side view, a top view, and an external photograph showing a state after the screwing operation of the male screw 1 to which the screw cover X1 is attached.
As shown in FIGS. 1A to 1C, the screw cover X1 is a resin member in which a screw mounting portion 21, a cover portion 22, and an elastic connecting portion 23 are integrally formed in a substantially U-shape. . The screw cover X1 has elasticity to maintain the state shown in FIGS. The material forming the screw cover X1 is not limited to resin, but it is desirable that the heat conduction efficiency from the male screw 1 is as low as possible.
The screw mounting portion 21 has an insertion opening 21a into which the body portion 11 (see FIG. 1D) of the male screw 1 is inserted.
The cover portion 22 covers the entire head portion 12 of the male screw 1 so that the head portion 12 does not touch a human hand. Note that the cover portion 22 may cover the head 12 of the male screw 1 to make it difficult for the head 12 to touch a human hand. Further, the cover portion 22 may be composed of a plurality of cover pieces as described in the first and second embodiments.

そして,前記弾性連結部23は,前記ネジ装着部21の嵌挿孔21aに嵌挿された前記雄ネジ1の頭部12を覆う方向に前記カバー部22が弾性を有するように前記ネジ装着部21及び前記カバー部22を連結している。
前記ネジカバーX1は,外部からの力が作用していない状態では,弾性によって図1(a)に示すように略コの字状を成す状態で維持される。なお,前記ネジカバーX1は,前記弾性連結部23が,前記ネジ装着部21及び前記弾性連結部23の連結部を支点に,前記カバー部22が前記雄ネジ1の頭部12を覆う方向に弾性を有する構成であってもよい。
一方,図1(g),(h)に示すように,前記雄ネジ1が螺着される筐体4(被螺着部材の一例)には,前記雄ネジ1が螺合されるネジ溝が形成された雌ネジ42が設けられている。前記雌ネジ42は,該雌ネジ42に螺着された後の前記雄ネジ1を前記筐体4の表面から突出させないように,前記筐体4に設けられた凹部41内に設けられている。また,前記凹部41は,前記ネジカバーX1が装着されたときに,該ネジカバーX1のカバー部22との間に隙間を形成するべく,該カバー部22よりも大きく形成されている。
The elastic connecting portion 23 is formed so that the cover portion 22 has elasticity in a direction covering the head 12 of the male screw 1 inserted into the insertion hole 21a of the screw mounting portion 21. 21 and the cover part 22 are connected.
The screw cover X1 is maintained in a substantially U-shaped state as shown in FIG. 1A due to elasticity when no external force is applied. The screw cover X1 is elastic in such a direction that the elastic connecting portion 23 covers the connecting portion of the screw mounting portion 21 and the elastic connecting portion 23, and the cover portion 22 covers the head 12 of the male screw 1. The structure which has this may be sufficient.
On the other hand, as shown in FIGS. 1 (g) and 1 (h), a thread groove into which the male screw 1 is screwed into a casing 4 (an example of a member to be screwed) into which the male screw 1 is screwed. A female screw 42 is provided. The female screw 42 is provided in a recess 41 provided in the housing 4 so that the male screw 1 after being screwed onto the female screw 42 does not protrude from the surface of the housing 4. . The concave portion 41 is formed larger than the cover portion 22 so as to form a gap with the cover portion 22 of the screw cover X1 when the screw cover X1 is attached.

続いて,図1を参照しつつ,前記ネジカバーX1を用いて前記雄ネジ1を前記筐体4に螺着するための作業者の螺着作業について説明する。
作業者はまず,図1(d)〜(f)に示すように,前記ネジカバーX1のカバー部22を押し上げて,前記雄ネジ1の胴部11を前記ネジ装着部21の嵌挿孔21a(図1(b),(c)参照)に嵌挿する。これにより,前記雄ネジ1が前記ネジカバーX1に装着される。
このとき,前記ネジカバーX1のカバー部22を,前記雄ネジ1の頭部12の周部に当接させることにより,該頭部12の中心部を開放させた状態にする。これにより,前記雄ネジ1の頭部12に工具3を当てて,該雄ネジ1を回転させることが可能となる。
Next, an operator's screwing operation for screwing the male screw 1 to the housing 4 using the screw cover X1 will be described with reference to FIG.
First, as shown in FIGS. 1D to 1F, the operator pushes up the cover portion 22 of the screw cover X1, and the body portion 11 of the male screw 1 is inserted into the insertion insertion hole 21a ( 1 (b) and (c)). Thereby, the male screw 1 is attached to the screw cover X1.
At this time, the center portion of the head 12 is opened by bringing the cover portion 22 of the screw cover X1 into contact with the peripheral portion of the head 12 of the male screw 1. As a result, the male screw 1 can be rotated by applying the tool 3 to the head 12 of the male screw 1.

そして,作業者は図1(g),(h)に示すように,前記雄ネジ1の頭部12に工具3を当て,該雄ネジ1を前記雌ネジ42に螺合させる。
このとき,前記雄ネジ1の頭部12の周部に当接されていた前記カバー部22は,前記雄ネジ1が前記雌ネジ42に螺合されるに従って前記工具3側に移動する。そして,前記カバー部22は,前記工具3に当接して保持される。なお,図1(g),(h)は,前記雄ネジ1が前記雌ネジ42に最後まで螺合された螺着後の状態を示している。
Then, as shown in FIGS. 1G and 1H, the operator applies the tool 3 to the head 12 of the male screw 1 and screws the male screw 1 into the female screw 42.
At this time, the cover portion 22 that is in contact with the peripheral portion of the head 12 of the male screw 1 moves toward the tool 3 as the male screw 1 is screwed into the female screw 42. The cover portion 22 is held in contact with the tool 3. 1 (g) and 1 (h) show a state after screwing in which the male screw 1 is screwed to the female screw 42 to the end.

その後,図1(i)〜(k)に示すように,前記工具3を前記雄ネジ1の頭部12から離間させると,該工具3に当接して保持されていた前記カバー部22は,弾性によって前記雄ネジ1の頭部12を覆う方向に変形する。これにより,前記雄ネジ1の頭部12は,その全部が前記カバー部22によってカバーされる。
また,前記雄ネジ1及び前記ネジカバーX1は,前記筐体4の凹部41内に収められるため該筐体4から突出しない。但し,これに限られず,前記筐体4に凹部41が設けられていない構成であってもかまわない。この場合には,前記雄ネジ1や前記ネジカバーX1が前記筐体4から突出することになるが,前記雄ネジ1の頭部12は前記ネジカバーX1のカバー部22によって覆われる。
このように,前記ネジカバーX1が装着された前記雄ネジ1が前記筐体4に螺着された後は,該雄ネジ1の頭部12に人が容易に触れることができない構造が実現される。従って,仮に前記雄ネジ1が高温になるような事態が生じても,前記雄ネジ1に人が触れる危険性を低減することができ,機器の安全性を高めることができる。
なお,前記筐体4に螺着された前記雄ネジ1を取り外す際は,前記凹部41と前記カバー部22との間の隙間から該カバー部22を押し上げることで,前記雄ネジ1の頭部12に前記工具3を当てることが可能である。
Thereafter, as shown in FIGS. 1 (i) to 1 (k), when the tool 3 is separated from the head 12 of the male screw 1, the cover portion 22 held in contact with the tool 3 is: It is deformed in a direction to cover the head 12 of the male screw 1 by elasticity. As a result, the entire head 12 of the male screw 1 is covered by the cover portion 22.
Further, the male screw 1 and the screw cover X1 do not protrude from the housing 4 because they are stored in the recess 41 of the housing 4. However, the present invention is not limited to this, and a configuration in which the recess 41 is not provided in the housing 4 may be employed. In this case, the male screw 1 and the screw cover X1 protrude from the housing 4, but the head 12 of the male screw 1 is covered by the cover portion 22 of the screw cover X1.
In this way, after the male screw 1 with the screw cover X1 attached is screwed to the housing 4, a structure in which a person cannot easily touch the head 12 of the male screw 1 is realized. . Therefore, even if a situation occurs in which the male screw 1 becomes hot, the risk of human touching the male screw 1 can be reduced, and the safety of the device can be improved.
When removing the male screw 1 screwed into the housing 4, the head portion of the male screw 1 is pushed up by pushing up the cover portion 22 from the gap between the concave portion 41 and the cover portion 22. It is possible to apply the tool 3 to 12.

以上説明したように,前記ネジカバーX1を前記雄ネジ1に装着し,該雄ネジ1を前記筐体4に螺着するだけで,前記雄ネジ1の頭部12は,前記ネジカバーX1のカバー部22によって覆われる。従って,前記雄ネジ1を前記筐体4に螺着した後で,前記カバー部22を折り曲げるなどの作業を省略することができ,作業効率を向上させることができる。
また,前記ネジ装着部21は,前記雄ネジ1の頭部12と前記雌ネジ42との間に介在することになるため,ワッシャーやスペーサー等として兼用することも可能である。
As described above, the head 12 of the male screw 1 can be attached to the cover portion of the screw cover X1 simply by attaching the screw cover X1 to the male screw 1 and screwing the male screw 1 to the housing 4. 22 is covered. Therefore, after the male screw 1 is screwed to the housing 4, the work such as bending the cover portion 22 can be omitted, and work efficiency can be improved.
Further, since the screw mounting portion 21 is interposed between the head 12 of the male screw 1 and the female screw 42, it can also be used as a washer, a spacer or the like.

As shown in FIGS. 2A and 2B, the screw cover X2 is a resin member in which a screw mounting portion 51, a cover portion 52, and an elastic connecting portion 53 are integrally formed. The screw cover X2 has elasticity to maintain the state of FIGS. 2 (a) and 2 (b). The material forming the screw cover X2 is not limited to resin, but it is desirable that the heat conduction efficiency from the male screw 1 is as low as possible.
The screw mounting portion 51 has an insertion opening 51a into which the body portion 11 (see FIG. 2C) of the male screw 1 is inserted.
The cover 52 covers the entire head 12 of the male screw 1 so that the head 12 does not touch a human hand. Note that the cover 52 may cover the head 12 of the male screw 1 to make it difficult for the head 12 to touch a human hand.

そして,前記弾性連結部53は,外部からの力が作用していない状態では,図2(a),(b)に示すように,前記カバー部52が前記ネジ装着部51の嵌挿孔51aの上方を開放する状態が維持されるよう前記ネジ装着部51及び前記カバー部52を連結している。
そのため,図2(c),(d)に示すように,前記ネジカバーX2が前記雄ネジ1に装着されたとき,前記カバー部52は,少なくとも前記雄ネジ1の頭部12の中心部を開放することになる。
一方,前述したように,前記筐体4(被螺着部材の一例)には,前記凹部41及び前記雌ネジ42が設けられている(図2(e),(f)参照)。ここで,前記凹部41は,その内部の側壁が,前記雄ネジ1が前記ネジカバーX2に装着された状態で前記雌ネジ42に螺着される際に該ネジカバーX2の前記弾性連結部53に接触するように形成されている。
When the external connection force is not applied to the elastic connecting portion 53, the cover portion 52 is inserted into the insertion hole 51a of the screw mounting portion 51 as shown in FIGS. 2 (a) and 2 (b). The screw mounting part 51 and the cover part 52 are connected so that the state where the upper part of the cover is opened is maintained.
Therefore, as shown in FIGS. 2 (c) and 2 (d), when the screw cover X 2 is attached to the male screw 1, the cover portion 52 opens at least the central portion of the head 12 of the male screw 1. Will do.
On the other hand, as described above, the casing 4 (an example of a member to be screwed) is provided with the concave portion 41 and the female screw 42 (see FIGS. 2E and 2F). Here, the concave portion 41 has an inner side wall that contacts the elastic connecting portion 53 of the screw cover X2 when the male screw 1 is screwed to the female screw 42 with the male screw 1 mounted on the screw cover X2. It is formed to do.

続いて,図2を参照しつつ,前記ネジカバーX2を用いて前記雄ネジ1を前記筐体4に螺着するための作業者の螺着作業について説明する。
作業者はまず,図2(c),(d)に示すように,前記雄ネジ1の胴部11を前記ネジカバーX2のネジ装着部51の嵌挿孔51aに嵌挿することにより,該雄ネジ1を前記ネジカバーX2に装着する。このように,前記雄ネジ1が前記ネジ装着部51に嵌挿された状態であっても,前記筐体4の雌ねじ42に螺着される前は,前記ネジカバーX2のカバー部52は,前記雄ネジ1の頭部12の中心部を開放している。従って,前記雄ネジ1の頭部12に工具3を当てて,該雄ネジ1を回転させることが可能である。なお,ここでは,前記雄ネジ1の頭部12の中心部だけを開放する場合を例に挙げているが,前記頭部12を全て開放する構成であってもかまわない。
Next, an operator's screwing operation for screwing the male screw 1 to the housing 4 using the screw cover X2 will be described with reference to FIG.
As shown in FIGS. 2 (c) and 2 (d), the worker first inserts the body 11 of the male screw 1 into the insertion hole 51a of the screw mounting portion 51 of the screw cover X2 to thereby insert the male screw 1. The screw 1 is attached to the screw cover X2. As described above, even when the male screw 1 is inserted into the screw mounting portion 51, the cover portion 52 of the screw cover X <b> 2 is formed before the female screw 42 of the housing 4 is screwed. The central part of the head 12 of the male screw 1 is opened. Therefore, the male screw 1 can be rotated by applying the tool 3 to the head 12 of the male screw 1. Here, a case where only the central portion of the head 12 of the male screw 1 is opened is described as an example, but a configuration in which the head 12 is entirely opened may be used.

そして,作業者は図2(e),(f)に示すように,前記雄ネジ1の頭部12に工具3を当て,該雄ネジ1を前記雌ネジ42に螺着させる。ここでいう螺着とは,前記雄ネジ1を前記雌ネジ42に最後まで螺合させた状態を言い,図2(e),(f)はその螺着後の状態を示している。
このとき,前記弾性連結部53が前記凹部41の内部の側壁に接触して,前記凹部41の内部の側壁に沿うように変形する。これにより,前記雄ネジ1に装着された前記ネジカバーX2のカバー部52には,前記雄ネジ1の頭部12を覆う方向へ変形するための力が作用することになる。但し,このとき前記雄ネジ1の頭部12には工具3が当てられているため,前記カバー部52は,前記工具3に当接した状態で保持されることになる。
Then, as shown in FIGS. 2 (e) and 2 (f), the operator applies the tool 3 to the head 12 of the male screw 1 and screwes the male screw 1 to the female screw 42. The screwing here means a state in which the male screw 1 is screwed to the female screw 42 to the end, and FIGS. 2 (e) and 2 (f) show a state after the screwing.
At this time, the elastic connecting portion 53 contacts the side wall inside the concave portion 41 and is deformed along the side wall inside the concave portion 41. As a result, a force for deforming in the direction covering the head 12 of the male screw 1 acts on the cover portion 52 of the screw cover X2 attached to the male screw 1. However, since the tool 3 is applied to the head 12 of the male screw 1 at this time, the cover 52 is held in contact with the tool 3.

その後,前記工具3を前記雄ネジ1の頭部12から離間させると,図2(g),(h)に示すように,前記工具3に当接して保持されていた前記カバー部52は,前記ネジカバーX2の弾性連結部53が前記筐体4の凹部41に接触することにより作用する力によって,前記雄ネジ1の頭部12を覆う方向に変形する。これにより,前記雄ネジ1の頭部12は,その全部が前記カバー部52によってカバーされる。このとき,前記雄ネジ1及び前記ネジカバーX2は,前記筐体4の凹部41内に収められるため該筐体4から突出しない。
このように,前記雄ネジ1が前記ネジ装着部51に嵌挿された状態で前記筐体4の雌ねじ42に螺着された後は,前記カバー部52は,前記弾性連結部53が前記筐体4の凹部41の内面に接触することにより前記雄ネジ1の頭部12の全部を覆う方向に変形する。これにより,前記雄ネジ1の頭部12に人が容易に触れることができない構造が実現される。従って,仮に前記雄ネジ1が高温になるような事態が生じても,前記雄ネジ1に人が触れる危険性を低減することができ,機器の安全性を高めることができる。
なお,前述したように,前記筐体4に螺着された前記雄ネジ1を取り外す際は,前記凹部41と前記カバー部52との隙間から該カバー部52を押し上げることで,前記雄ネジ1の頭部12に前記工具3を当てることが可能である。
以上説明したように,前記ネジカバーX2を前記雄ネジ1に装着し,該雄ネジ1を前記筐体4に螺着するだけで,前記雄ネジ1の頭部12は,前記ネジカバーX2のカバー部52によって覆われる。従って,前記雄ネジ1を前記筐体4に螺着した後で,前記カバー部52を折り曲げるなどの作業を省略することができ,作業効率を向上させることができる。
Thereafter, when the tool 3 is separated from the head 12 of the male screw 1, as shown in FIGS. 2 (g) and 2 (h), the cover portion 52 held in contact with the tool 3 is: The elastic connecting portion 53 of the screw cover X <b> 2 is deformed in a direction to cover the head 12 of the male screw 1 by a force acting when the elastic connecting portion 53 contacts the concave portion 41 of the housing 4. As a result, the entire head 12 of the male screw 1 is covered by the cover portion 52. At this time, the male screw 1 and the screw cover X2 do not protrude from the housing 4 because they are housed in the recess 41 of the housing 4.
As described above, after the male screw 1 is fitted into the screw mounting portion 51 and screwed into the female screw 42 of the housing 4, the cover portion 52 has the elastic connecting portion 53 connected to the housing. By contacting the inner surface of the recess 41 of the body 4, the body 4 is deformed in a direction covering the entire head 12 of the male screw 1. Thereby, a structure in which a person cannot easily touch the head 12 of the male screw 1 is realized. Therefore, even if a situation occurs in which the male screw 1 becomes hot, the risk of human touching the male screw 1 can be reduced, and the safety of the device can be improved.
As described above, when removing the male screw 1 screwed to the housing 4, the male screw 1 is pushed up by pushing up the cover portion 52 from the gap between the concave portion 41 and the cover portion 52. It is possible to apply the tool 3 to the head 12.
As described above, the head 12 of the male screw 1 can be attached to the cover portion of the screw cover X2 simply by attaching the screw cover X2 to the male screw 1 and screwing the male screw 1 to the housing 4. 52. Therefore, after the male screw 1 is screwed to the housing 4, the operation such as bending the cover portion 52 can be omitted, and the working efficiency can be improved.

(第3の実施の形態)
次に,図3を用いて,本発明の第3の実施の形態に係るネジカバーX3について説明する。ここに,図3(a),(b)はネジカバーX3の側面図,上面図,図3(c),(d)はネジカバーX3の雄ネジ1への装着状態を示す側面図,上面図,図3(e),(f)はネジカバーX3が装着された雄ネジ1の螺着作業中の状態を示す側面図,上面図,図3(g),(h)はネジカバーX3が装着された雄ネジ1の螺着作業終了後の状態を示す側面図,上面図である。
図3(a),(b)に示すように,前記ネジカバーX3は,ネジ装着部61,カバー部62,弾性連結部63及び弾性連結部64が,一体形成された樹脂製の部材である。前記ネジカバーX3は,図3(a),(b)の状態を維持する弾性を有している。なお,前記ネジカバーX3を形成する材料は,樹脂に限られないが,前記雄ネジ1からの熱伝導効率ができるだけ低いものであることが望ましい。
前記ネジ装着部61は,前記雄ネジ1の胴部11(図3(c)参照)が嵌挿される嵌挿口61aを有している。
また,前記カバー部62は,前記雄ネジ1の頭部12の全部を覆うことで該頭部12が人の手に触れないようにカバーするためのものである。なお,前記カバー部62は,前記雄ネジ1の頭部12の一部を覆うことで該頭部12が人の手に触れにくくするものであってもかまわない。
(Third embodiment)
Next, a screw cover X3 according to a third embodiment of the present invention will be described with reference to FIG. 3A and 3B are a side view and a top view of the screw cover X3, and FIGS. 3C and 3D are a side view and a top view showing the mounting state of the screw cover X3 on the male screw 1. FIGS. 3E and 3F are a side view and a top view showing a state in which the male screw 1 to which the screw cover X3 is attached is being screwed, and FIGS. 3G and 3H are views in which the screw cover X3 is attached. It is the side view and top view which show the state after completion | finish of the screwing operation | work of the external thread.
As shown in FIGS. 3A and 3B, the screw cover X3 is a resin member in which a screw mounting portion 61, a cover portion 62, an elastic connecting portion 63, and an elastic connecting portion 64 are integrally formed. The screw cover X3 has elasticity to maintain the state of FIGS. 3 (a) and 3 (b). The material forming the screw cover X3 is not limited to resin, but it is desirable that the heat conduction efficiency from the male screw 1 is as low as possible.
The screw mounting portion 61 has a fitting insertion opening 61a into which the body portion 11 (see FIG. 3C) of the male screw 1 is fitted.
The cover 62 covers the entire head 12 of the male screw 1 so that the head 12 does not touch a human hand. The cover portion 62 may cover the part of the head 12 of the male screw 1 to make it difficult for the head 12 to touch a human hand.

そして,前記弾性連結部63,64は,外部からの力が作用していない状態では,図3(a),(b)に示すように,前記カバー部62が前記ネジ装着部61の嵌挿孔61aの上方を開放する状態が維持されるよう前記ネジ装着部61及び前記カバー部62を連結している。
そのため,図3(c),(d)に示すように,前記ネジカバーX3が前記雄ネジ1に装着されたとき,前記カバー部62は,少なくとも前記雄ネジ1の頭部12の中心部を開放することになる。
一方,図3(e),(f)に示すように,前記筐体4(被螺着部材の一例)には前記雌ネジ42が設けられている。ここで,前記雌ネジ42は,前記第1の実施の形態及び前記第2の実施の形態とは異なり,前記筐体4の表面43に設けられている。
The elastic connecting portions 63 and 64 are inserted into the screw mounting portion 61 when the external force is not applied, as shown in FIGS. 3 (a) and 3 (b). The screw mounting portion 61 and the cover portion 62 are connected so that the state where the upper portion of the hole 61a is opened is maintained.
Therefore, as shown in FIGS. 3C and 3D, when the screw cover X3 is attached to the male screw 1, the cover portion 62 opens at least the central portion of the head 12 of the male screw 1. Will do.
On the other hand, as shown in FIGS. 3E and 3F, the housing 4 (an example of a member to be screwed) is provided with the female screw 42. Here, unlike the first embodiment and the second embodiment, the female screw 42 is provided on the surface 43 of the housing 4.

続いて,図3を参照しつつ,前記ネジカバーX3を用いて前記雄ネジ1を前記筐体4に螺着するための作業者の螺着作業について説明する。
作業者はまず,図3(c),(d)に示すように,前記雄ネジ1の胴部11を前記ネジカバーX3のネジ装着部61の嵌挿孔61aに嵌挿することにより,該雄ネジ1を前記ネジカバーX3に装着する。このように,前記雄ネジ1が前記ネジ装着部61に嵌挿された状態であっても,前記筐体4の雌ねじ42に螺着される前は,前記ネジカバーX3のカバー部62は,前記雄ネジ1の頭部12の中心部を開放している。従って,前記雄ネジ1の頭部12に工具3を当てて,該雄ネジ1を回転させることが可能である。なお,ここでは,前記雄ネジ1の頭部12の中心部だけを開放する場合を例に挙げているが,前記頭部12を全て開放する構成であってもかまわない。
Next, an operator's screwing operation for screwing the male screw 1 to the housing 4 using the screw cover X3 will be described with reference to FIG.
First, as shown in FIGS. 3C and 3D, the operator inserts the body 11 of the male screw 1 into the insertion hole 61a of the screw mounting portion 61 of the screw cover X3, thereby The screw 1 is attached to the screw cover X3. As described above, even when the male screw 1 is fitted into the screw mounting portion 61, the cover portion 62 of the screw cover X3 is in the state before being screwed to the female screw 42 of the housing 4. The central part of the head 12 of the male screw 1 is opened. Therefore, the male screw 1 can be rotated by applying the tool 3 to the head 12 of the male screw 1. Here, a case where only the central portion of the head 12 of the male screw 1 is opened is described as an example, but a configuration in which the head 12 is entirely opened may be used.

そして,作業者は図3(e),(f)に示すように,前記雄ネジ1の頭部12に工具3を当て,該雄ネジ1を前記雌ネジ42に螺着させる。
このとき,前記弾性連結部63が前記筐体4の表面43に接触して,該表面43に沿うように変形する。これにより,前記雄ネジ1に装着された前記ネジカバーX3のカバー部62には,前記雄ネジ1の頭部12を覆う方向へ変形するための力が作用することになる。但し,このとき前記雄ネジ1の頭部12には工具3が当てられているため,前記カバー部62は,前記工具3に当接した状態で保持されることになる。
Then, as shown in FIGS. 3 (e) and 3 (f), the operator applies the tool 3 to the head 12 of the male screw 1 and screwes the male screw 1 to the female screw 42.
At this time, the elastic connecting portion 63 comes into contact with the surface 43 of the housing 4 and deforms along the surface 43. As a result, a force for deforming in the direction covering the head 12 of the male screw 1 acts on the cover portion 62 of the screw cover X3 attached to the male screw 1. However, since the tool 3 is applied to the head 12 of the male screw 1 at this time, the cover portion 62 is held in contact with the tool 3.

その後,前記工具3を前記雄ネジ1の頭部12から離間させると,図3(g),(h)に示すように,前記工具3に当接して保持されていた前記カバー部62は,前記ネジカバーX3の弾性連結部63が前記筐体4の表面43に接触することにより作用する力によって,前記雄ネジ1の頭部12を覆う方向に変形する。これにより,前記雄ネジ1の頭部12は,その全部が前記カバー部62によってカバーされる。
このように,前記雄ネジ1が前記ネジ装着部61に嵌挿された状態で前記筐体4の雌ねじ42に螺着された後は,前記カバー部62は,前記弾性連結部63が前記筐体4の表面43に接触することにより前記雄ネジ1の頭部12の全部を覆う方向に変形する。これにより,前記雄ネジ1の頭部12に人が容易に触れることができない構造が実現される。従って,仮に前記雄ネジ1が高温になるような事態が生じても,前記雄ネジ1に人が触れる危険性を低減することができ,機器の安全性を高めることができる。
以上説明したように,前記ネジカバーX3を前記雄ネジ1に装着し,該雄ネジ1を前記筐体4に螺着するだけで,前記雄ネジ1の頭部12は,前記ネジカバーX3のカバー部62によって覆われる。従って,前記雄ネジ1を前記筐体4に螺着した後で,前記カバー部62を折り曲げるなどの作業を省略することができ,作業効率を向上させることができる。
また,前記ネジカバーX3の構成では,前記ネジカバーX2(図2参照)のように前記筐体4に凹部41を設けておく必要がないため,該筐体4をより薄型化することが可能である。もちろん,前記雄ネジ1及び前記ネジカバーX3を前記筐体4の表面43から突出させないように,前記凹部41を設けておくことも他の実施例として考えられる。
Thereafter, when the tool 3 is separated from the head 12 of the male screw 1, as shown in FIGS. 3 (g) and 3 (h), the cover portion 62 held in contact with the tool 3 is: The elastic connecting portion 63 of the screw cover X3 is deformed in a direction to cover the head 12 of the male screw 1 by a force acting when the elastic connecting portion 63 contacts the surface 43 of the housing 4. As a result, the entire head 12 of the male screw 1 is covered by the cover portion 62.
As described above, after the male screw 1 is screwed into the female screw 42 of the housing 4 in a state where the male screw 1 is fitted into the screw mounting portion 61, the cover portion 62 has the elastic connecting portion 63 connected to the housing. By contacting the surface 43 of the body 4, it deforms in a direction covering the entire head 12 of the male screw 1. Thereby, a structure in which a person cannot easily touch the head 12 of the male screw 1 is realized. Therefore, even if a situation occurs in which the male screw 1 becomes hot, the risk of human touching the male screw 1 can be reduced, and the safety of the device can be improved.
As described above, the head 12 of the male screw 1 can be attached to the cover portion of the screw cover X3 simply by attaching the screw cover X3 to the male screw 1 and screwing the male screw 1 to the housing 4. 62. Therefore, after the male screw 1 is screwed to the housing 4, the operation of bending the cover portion 62 can be omitted, and the working efficiency can be improved.
Further, in the configuration of the screw cover X3, there is no need to provide the recess 41 in the housing 4 unlike the screw cover X2 (see FIG. 2), and therefore the housing 4 can be made thinner. . Of course, it is also conceivable as another embodiment that the concave portion 41 is provided so that the male screw 1 and the screw cover X3 do not protrude from the surface 43 of the housing 4.

本実施例1では,前記第2の実施の形態で説明した前記ネジカバーX2(図2参照)の変形例であるネジカバーX21について説明する。なお,前記ネジカバーX2と同様の構成には同じ符号を付してその説明を省略する。
ここに,図4は,本実施例1に係るネジカバーX21の構造を説明するための図である。また,図4(a),(b),(c)はネジカバーX21の側面図,上面図,外観写真,図4(d),(e),(f)はネジカバーX21の雄ネジ1への装着状態を示す側面図,上面図,外観写真,図4(g),(h)はネジカバーX21が装着された雄ネジ1の螺着作業中の状態を示す側面図,上面図,図4(i),(j),(k)はネジカバーX21が装着された雄ネジ1の螺着作業終了後の状態を示す側面図,上面図,外観写真である。
In Example 1, a screw cover X21, which is a modification of the screw cover X2 (see FIG. 2) described in the second embodiment, will be described. In addition, the same code | symbol is attached | subjected to the structure similar to the said screw cover X2, and the description is abbreviate | omitted.
FIG. 4 is a diagram for explaining the structure of the screw cover X21 according to the first embodiment. 4 (a), (b), and (c) are side views, top views, and external photographs of the screw cover X21, and FIGS. 4 (d), (e), and (f) are views of the screw cover X21 attached to the male screw 1. FIGS. 4 (g) and 4 (h) are a side view, a top view, and an external view showing the mounting state. FIGS. 4 (g) and 4 (h) are a side view, a top view, and FIG. i), (j), and (k) are a side view, a top view, and an external photograph showing a state after the screwing operation of the male screw 1 to which the screw cover X21 is attached.

図4(a)〜(c)に示すように,前記ネジカバーX21は,前記ネジカバーX2のカバー部52(図2参照)に換えて,前記雄ネジ1の頭部12を覆うための略扇形の4つのカバー片71を有している。
また,前記カバー片71各々には,螺着された後の前記雄ネジ1の頭部12を覆う際に,該頭部12の中心部を開放する隙間を形成するべく,切り欠き71aが形成されている。
前記カバー片71各々は,複数の前記弾性連結部53によって前記ネジ装着部51に連結されている。前記弾性連結部53各々は,外部からの力が作用していない状態では,図4(a)〜(c)に示すように,前記カバー片71が前記ネジ装着部51の嵌挿孔51aの上方を開放する状態が維持されるよう前記ネジ装着部51及び前記カバー片71各々を連結している。
そのため,図4(d)〜(f)に示すように,前記ネジカバーX21が前記雄ネジ1に装着されたとき,前記カバー片71各々は,少なくとも前記雄ネジ1の頭部12の中心部を開放することになる。
As shown in FIGS. 4A to 4C, the screw cover X21 is substantially fan-shaped to cover the head 12 of the male screw 1 instead of the cover portion 52 (see FIG. 2) of the screw cover X2. Four cover pieces 71 are provided.
Each of the cover pieces 71 is formed with a notch 71a so as to form a gap that opens the central portion of the head 12 when the head 12 of the male screw 1 after being screwed is covered. Has been.
Each of the cover pieces 71 is connected to the screw mounting portion 51 by a plurality of the elastic connecting portions 53. In the state where the external force is not applied to each of the elastic connecting portions 53, as shown in FIGS. 4 (a) to 4 (c), the cover piece 71 is inserted into the insertion hole 51a of the screw mounting portion 51. The screw mounting portion 51 and the cover piece 71 are connected to each other so as to maintain a state where the upper side is opened.
Therefore, as shown in FIGS. 4D to 4F, when the screw cover X21 is attached to the male screw 1, each of the cover pieces 71 has at least the center portion of the head 12 of the male screw 1. Will be released.

続いて,図4を参照しつつ,前記ネジカバーX21を用いて前記雄ネジ1を前記筐体4に螺着するための作業者の螺着作業について説明する。
作業者はまず,図4(d)〜(f)に示すように,前記雄ネジ1の胴部11を前記ネジカバーX21のネジ装着部51の嵌挿孔51aに嵌挿することにより,該雄ネジ1を前記ネジカバーX21に装着する。このとき,前記ネジカバーX21のカバー片71各々は,前記雄ネジ1の頭部12の中心部を開放する状態で維持されている。従って,前記雄ネジ1の頭部12に工具3を当てて,該雄ネジ1を回転させることが可能である。
Next, an operator's screwing operation for screwing the male screw 1 to the housing 4 using the screw cover X21 will be described with reference to FIG.
First, as shown in FIGS. 4D to 4F, the operator inserts the body 11 of the male screw 1 into the insertion hole 51a of the screw mounting portion 51 of the screw cover X21. The screw 1 is attached to the screw cover X21. At this time, each of the cover pieces 71 of the screw cover X21 is maintained in a state in which the central portion of the head 12 of the male screw 1 is opened. Therefore, the male screw 1 can be rotated by applying the tool 3 to the head 12 of the male screw 1.

そして,作業者は図4(g),(h)に示すように,前記雄ネジ1の頭部12に工具3を当て,該雄ネジ1を前記雌ネジ42に螺着させる。
このとき,前記弾性連結部53が前記凹部41の内部の側壁に接触して,前記凹部41の内部の側壁に沿うように変形する。これにより,前記雄ネジ1に装着された前記ネジカバーX21のカバー片71各々には,前記雄ネジ1の頭部12を覆う方向へ変形するための力が作用することになる。但し,このとき前記雄ネジ1の頭部12には工具3が当てられているため,前記カバー片71各々は,前記工具3に当接した状態で保持されることになる。
その後,前記工具3を前記雄ネジ1の頭部12から離間させると,図4(i)〜(k)に示すように,前記工具3に当接して保持されていた前記カバー片71各々が,前記弾性連結部53が前記筐体4の凹部41に接触することにより作用する力によって,前記雄ネジ1の頭部12を覆う方向に変形する。これにより,前記雄ネジ1の頭部12は,複数の前記カバー片71によってカバーされる。
Then, as shown in FIGS. 4G and 4H, the operator applies the tool 3 to the head 12 of the male screw 1 and screws the male screw 1 onto the female screw 42.
At this time, the elastic connecting portion 53 contacts the side wall inside the concave portion 41 and is deformed along the side wall inside the concave portion 41. Accordingly, a force for deforming the cover piece 71 of the screw cover X21 attached to the male screw 1 in a direction to cover the head 12 of the male screw 1 acts. However, since the tool 3 is applied to the head 12 of the male screw 1 at this time, each of the cover pieces 71 is held in contact with the tool 3.
Thereafter, when the tool 3 is moved away from the head 12 of the male screw 1, each of the cover pieces 71 held in contact with the tool 3 is held as shown in FIGS. The elastic connecting portion 53 is deformed in a direction to cover the head 12 of the male screw 1 by a force acting when the elastic connecting portion 53 comes into contact with the concave portion 41 of the housing 4. Thereby, the head 12 of the male screw 1 is covered by the plurality of cover pieces 71.

また,前記ネジカバーX21では,前記カバー片71各々に前記切り欠き71aが形成されており,該切り欠き71aによって前記雄ネジ1の頭部12の中心部が開放される。そのため,前記雄ネジ1を螺着した後でも,前記工具3を前記雄ネジ1の頭部12に容易に当てることが可能である。例えば,前記工具3を前記カバー片71の上方から前記頭部12に向けて差し込むことで,該工具3を前記頭部12に当てることが可能である。
もちろん,前記ネジカバーX21は,図5(a),(b)に示すように,前記カバー片71が前記切り欠き71aを有しない構成であってもかまわない。この場合には,図5(c),(d)に示すように,前記雄ネジ1が前記筐体4に螺着されると,前記雄ネジ1の頭部12の中心部が覆われることになるが,前記雄ネジ1を取り外す際には,前記カバー片71各々を押し上げて,前記雄ネジ1の頭部12に前記工具3を当てればよい。
なお,本実施例1では,4つのカバー片71を有する前記ネジカバーX21を,前記ネジカバーX2の変形例として説明したが,前記ネジカバーX1,X3の変形例として同様の構成を採用することも考えられる。例えば,前記ネジカバーX1に適用する場合には,前記カバー片71と同様の4つのカバー片を,前記ネジ装着部21の嵌挿孔21aに嵌挿された前記雄ネジ1の頭部12を覆う方向に弾性を有するように設ければよい。
Further, in the screw cover X21, the cutout 71a is formed in each of the cover pieces 71, and the central portion of the head 12 of the male screw 1 is opened by the cutout 71a. Therefore, even after the male screw 1 is screwed, the tool 3 can be easily applied to the head 12 of the male screw 1. For example, the tool 3 can be applied to the head 12 by inserting the tool 3 from above the cover piece 71 toward the head 12.
Of course, as shown in FIGS. 5A and 5B, the screw cover X21 may be configured such that the cover piece 71 does not have the notch 71a. In this case, as shown in FIGS. 5C and 5D, when the male screw 1 is screwed to the housing 4, the center portion of the head 12 of the male screw 1 is covered. However, when removing the male screw 1, each of the cover pieces 71 may be pushed up and the tool 3 may be applied to the head 12 of the male screw 1.
In the first embodiment, the screw cover X21 having the four cover pieces 71 has been described as a modified example of the screw cover X2, but a similar configuration may be adopted as a modified example of the screw covers X1 and X3. . For example, when applied to the screw cover X1, four cover pieces similar to the cover piece 71 cover the head 12 of the male screw 1 inserted into the insertion hole 21a of the screw mounting portion 21. What is necessary is just to provide so that it may have elasticity in a direction.

In Example 2, a screw cover X31, which is a modification of the screw cover X3 (see FIG. 3) described in the third embodiment, will be described. In addition, the same code | symbol is attached | subjected to the structure similar to the said screw cover X3, and the description is abbreviate | omitted.
FIG. 6 is a diagram for explaining the structure of the screw cover X31 according to the second embodiment. 6 (a) and 6 (b) are side views and top views of the screw cover X31, and FIGS. 6 (c) and 6 (d) are side views, top views, and diagrams showing the mounting state of the screw cover X31 on the male screw 1. 6 (e) and (f) are a side view and a top view showing a state in which the male screw 1 to which the screw cover X31 is attached is being screwed, and FIGS. 6 (g) and 6 (h) are male to which the screw cover X31 is attached. FIG. 4 is a side view and a top view showing a state after the screwing operation of the screw 1 is completed.

図6(a),(b)に示すように,前記ネジカバーX31は,前記ネジカバーX3のカバー部62(図3参照)に換えて,前記雄ネジ1の頭部12を覆うための略半円形状の2つのカバー片81を有している。
また,前記カバー片81各々には,螺着された後の前記雄ネジ1の頭部12を覆う際に,該頭部12の中心部を開放する隙間を形成するべく,切り欠き81aが形成されている。
前記カバー片81各々は,前記弾性連結部63,64によって前記ネジ装着部61に連結されている。前記弾性連結部63,64は,外部からの力が作用していない状態では,図6(a),(b)に示すように,前記カバー片81が前記ネジ装着部61の嵌挿孔61aの上方を開放する状態が維持されるよう前記ネジ装着部61及び前記カバー片81各々を連結している。
そのため,図6(c),(d)に示すように,前記ネジカバーX31が前記雄ネジ1に装着されたとき,前記カバー片81各々は,少なくとも前記雄ネジ1の頭部12の中心部を開放することになる。
As shown in FIGS. 6 (a) and 6 (b), the screw cover X31 is substantially semicircular to cover the head 12 of the male screw 1 instead of the cover portion 62 (see FIG. 3) of the screw cover X3. It has two cover pieces 81 having a shape.
Each of the cover pieces 81 is formed with a notch 81a so as to form a gap that opens the central portion of the head 12 when the head 12 of the male screw 1 after being screwed is covered. Has been.
Each of the cover pieces 81 is connected to the screw mounting portion 61 by the elastic connecting portions 63 and 64. In the state where the external force is not applied, the elastic connecting portions 63 and 64 are configured such that the cover piece 81 is fitted into the insertion hole 61a of the screw mounting portion 61 as shown in FIGS. 6 (a) and 6 (b). The screw mounting portion 61 and the cover piece 81 are connected to each other so as to maintain a state in which the upper side is opened.
Therefore, as shown in FIGS. 6 (c) and 6 (d), when the screw cover X 31 is attached to the male screw 1, each of the cover pieces 81 has at least the center portion of the head 12 of the male screw 1. Will be released.

続いて,図6を参照しつつ,前記ネジカバーX31を用いて前記雄ネジ1を前記筐体4に螺着するための作業者の螺着作業について説明する。
作業者はまず,図6(c),(d)に示すように,前記雄ネジ1の胴部11を前記ネジカバーX31のネジ装着部61の嵌挿孔61aに嵌挿することにより,該雄ネジ1を前記ネジカバーX31に装着する。このとき,前記ネジカバーX31のカバー片81各々は,前記雄ネジ1の頭部12の中心部を開放する状態で維持されている。従って,前記雄ネジ1の頭部12に工具3を当てて,該雄ネジ1を回転させることが可能である。
Next, a screwing operation of an operator for screwing the male screw 1 to the housing 4 using the screw cover X31 will be described with reference to FIG.
First, as shown in FIGS. 6 (c) and 6 (d), the operator inserts the body 11 of the male screw 1 into the insertion hole 61a of the screw mounting portion 61 of the screw cover X31. The screw 1 is attached to the screw cover X31. At this time, each of the cover pieces 81 of the screw cover X31 is maintained in a state in which the central portion of the head 12 of the male screw 1 is opened. Therefore, the male screw 1 can be rotated by applying the tool 3 to the head 12 of the male screw 1.

そして,作業者は図6(e),(f)に示すように,前記雄ネジ1の頭部12に工具3を当て,該雄ネジ1を前記雌ネジ42に螺着させる。
このとき,前記弾性連結部63が前記筐体4の表面43に接触して,該表面43に沿うように変形する。これにより,前記雄ネジ1に装着された前記ネジカバーX31のカバー片81各々には,前記雄ネジ1の頭部12を覆う方向へ変形するための力が作用することになる。但し,このとき前記雄ネジ1の頭部12には工具3が当てられているため,前記カバー片81各々は,前記工具3に当接した状態で保持されることになる。
その後,前記工具3を前記雄ネジ1の頭部12から離間させると,図6(g),(h)に示すように,前記工具3に当接して保持されていた前記カバー片81各々は,前記弾性連結部63が前記筐体4の表面43に接触することにより作用する力によって,前記雄ネジ1の頭部12を覆う方向に変形する。これにより,前記雄ネジ1の頭部12は,複数の前記カバー片81によってカバーされる。
Then, as shown in FIGS. 6 (e) and 6 (f), the operator applies the tool 3 to the head 12 of the male screw 1 and screws the male screw 1 onto the female screw 42.
At this time, the elastic connecting portion 63 comes into contact with the surface 43 of the housing 4 and deforms along the surface 43. As a result, a force for deforming in the direction covering the head 12 of the male screw 1 acts on each cover piece 81 of the screw cover X31 attached to the male screw 1. However, since the tool 3 is applied to the head 12 of the male screw 1 at this time, each of the cover pieces 81 is held in contact with the tool 3.
Thereafter, when the tool 3 is separated from the head 12 of the male screw 1, each of the cover pieces 81 held in contact with the tool 3 is held as shown in FIGS. 6 (g) and 6 (h). The elastic connecting portion 63 is deformed in a direction to cover the head 12 of the male screw 1 by a force acting when the elastic connecting portion 63 comes into contact with the surface 43 of the housing 4. Thereby, the head 12 of the male screw 1 is covered with the plurality of cover pieces 81.

また,前記ネジカバーX31では,前記カバー片81各々に前記切り欠き81aが形成されており,該切り欠き81aによって前記雄ネジ1の頭部12の中心部が開放される。そのため,前記雄ネジ1を螺着した後でも,前記工具3を前記雄ネジ1の頭部12に容易に当てることが可能である。例えば,前記工具3を前記カバー片71の上方から前記頭部12に向けて差し込むことで,該工具3を前記頭部12に当てることが可能である。
もちろん,前記ネジカバーX31は,図7(a),(b)に示すように,前記カバー片81が前記切り欠き81aを有しない構成であってもかまわない。この場合には,図7(c),(d)に示すように,前記雄ネジ1が前記筐体4に螺着されると,前記雄ネジ1の頭部12の中心部が覆われることになるが,前記雄ネジ1を取り外す際には,前記カバー片81各々を押し上げて,前記雄ネジ1の頭部12に前記工具3を当てればよい。
なお,本実施例2では,複数のカバー片81を有する前記ネジカバーX31を,前記ネジカバーX3の変形例として説明したが,前記ネジカバーX1,X2の変形例として同様の構成を採用することも考えられる。例えば,前記ネジカバーX1に適用する場合には,前記カバー片81と同様の2つのカバー片を,前記ネジ装着部21の嵌挿孔21aに嵌挿された前記雄ネジ1の頭部12を覆う方向に弾性を有するように設ければよい。
Further, in the screw cover X31, the cutout 81a is formed in each of the cover pieces 81, and the central portion of the head 12 of the male screw 1 is opened by the cutout 81a. Therefore, even after the male screw 1 is screwed, the tool 3 can be easily applied to the head 12 of the male screw 1. For example, the tool 3 can be applied to the head 12 by inserting the tool 3 from above the cover piece 71 toward the head 12.
Of course, as shown in FIGS. 7A and 7B, the screw cover X31 may have a structure in which the cover piece 81 does not have the notch 81a. In this case, as shown in FIGS. 7C and 7D, when the male screw 1 is screwed to the housing 4, the central portion of the head 12 of the male screw 1 is covered. However, when the male screw 1 is removed, each of the cover pieces 81 may be pushed up and the tool 3 may be applied to the head 12 of the male screw 1.
In the second embodiment, the screw cover X31 having a plurality of cover pieces 81 has been described as a modified example of the screw cover X3. However, it is also conceivable to adopt the same configuration as a modified example of the screw covers X1 and X2. . For example, when applied to the screw cover X 1, two cover pieces similar to the cover piece 81 cover the head 12 of the male screw 1 inserted into the fitting hole 21 a of the screw mounting portion 21. What is necessary is just to provide so that it may have elasticity in a direction.
