Description

本発明は、インストルメントパネル等の車両側の設置母材に対して着脱可能となっている車載機器の取付構造に関するものである。   The present invention relates to a mounting structure for an in-vehicle device that is detachable from an installation base material on a vehicle side such as an instrument panel.

車両側の設置母材（インストルメントパネル等）に取り付けられているカーナビゲーションやカーオーディオ等の車載機器は、修理や交換のために取り外すことがあり、修理後には再び設置母材に取り付けられる。また、近年、この種の車載機器の利便性を高めるために、車両側の設置母材に取り付けた正規の状態だけでなく取り外した状態でも使用できるようにした車載機器が実用化されている。具体的には、ユーザがカーナビゲーション等の車載機器を取り外して、手持ちのビデオカメラやゲーム機等の外部機器と接続することにより、この車載機器の表示部や内蔵スピーカを利用して外部機器の映像や音声の情報が視聴できるようになっている。   In-vehicle devices such as car navigation and car audio attached to an installation base material (instrument panel or the like) on the vehicle side may be removed for repair or replacement, and are attached to the installation base material again after repair. In recent years, in order to enhance the convenience of this type of in-vehicle device, in-vehicle devices that can be used not only in a normal state attached to a vehicle-side installation base material but also in a removed state have been put into practical use. Specifically, when a user removes an in-vehicle device such as a car navigation system and connects it to an external device such as a video camera or a game machine, the external device is displayed using the display unit or the built-in speaker of the in-vehicle device. Video and audio information can be viewed.

このように車両側の設置母材に着脱可能な車載機器の取付構造を少ない部品点数で安価に実現している従来技術として、車載機器のシャーシ等の筐体部分の左右両側面にそれぞれ板ばねを固定し、各板ばねのフック部を設置母材（インストルメントパネル）に掛止させるという構造のものが知られている（例えば、特許文献１参照）。   As a conventional technique that realizes an in-vehicle device mounting structure that can be attached to and detached from an installation base material on the vehicle side at a low cost with a small number of parts, leaf springs are respectively provided on the left and right side surfaces of a housing portion such as a chassis of the in-vehicle device. Is fixed, and a hook portion of each leaf spring is hooked to an installation base material (instrument panel) (for example, see Patent Document 1).

かかる従来の取付構造において、左右の板ばねの自由端側にはフック部が折曲形成されており、このフック部が車載機器の筐体部分の側方へくの字状に張り出しているため、車両側の設置母材の内壁部に各板ばねのフック部を抜け止め状態で掛止させることができる。また、車載機器を設置母材から取り外す際には、機器本体に形成されているスロットに取外し治具（リリースキー）を挿入し、この取外し治具で板ばねを弾性変形させることにより、左右の板ばねのフック部を設置母材に掛止されない退避位置まで移動させ、この状態で車載機器を手前へ引っ張って設置母材から取り外すようになっている。なお、取り外した車載機器を設置母材に対し嵌め込むように押し込めば、この車載機器を各板ばねの撓みを利用してスナップ装着させることができる。   In such a conventional mounting structure, a hook portion is bent at the free end side of the left and right leaf springs, and this hook portion projects in a laterally U-shape from the housing portion of the in-vehicle device. The hook portions of the leaf springs can be hooked to the inner wall portion of the base metal on the vehicle side in a retaining state. Also, when removing the in-vehicle device from the installation base material, a removal jig (release key) is inserted into the slot formed in the device body, and the leaf spring is elastically deformed by this removal jig, so The hook portion of the leaf spring is moved to a retracted position where it is not hooked by the installation base material, and in this state, the in-vehicle device is pulled forward and removed from the installation base material. In addition, if it pushes in so that the removed vehicle equipment may be inserted with respect to an installation base material, this vehicle equipment can be snap-mounted using the bending of each leaf | plate spring.

しかしながら、前述した従来の取付構造においては、板ばねの奥行き寸法を長めに設定しておかないとフック部に所要の撓み量が確保できないため、奥行き寸法の短い車載機器には適用できないという問題があった。また、かかる従来の取付構造においては、板ばねのフック部をある程度撓み易く設定しておかないと、車載機器の着脱作業に支障を来す虞があるため、車両側の設置母材に対する車載機器の取付強度が不足し易いという問題があった。なお、取付強度を高めるために板ばねのフック部を撓みにくくしておくと、車載機器の着脱作業が煩雑になるばかりか、着脱時にフック部が塑性変形して車載機器の正常な取付が行えなくなってしまう虞がある。   However, the above-described conventional mounting structure has a problem that it cannot be applied to in-vehicle devices with a short depth dimension because the required deflection amount cannot be secured in the hook portion unless the depth dimension of the leaf spring is set long. there were. In addition, in such a conventional mounting structure, if the hook portion of the leaf spring is not set to be bent to some extent, there is a risk of hindering the mounting / demounting operation of the in-vehicle device. There has been a problem that the mounting strength of is likely to be insufficient. If the hook part of the leaf spring is made difficult to bend in order to increase the mounting strength, not only the mounting / dismounting operation of the in-vehicle device becomes complicated, but also the mounting of the in-vehicle device can be performed normally due to plastic deformation of the hook portion during mounting / dismounting. There is a risk of disappearing.

本発明は、このような従来技術の実情に鑑みてなされたもので、その目的は、奥行き寸法の短い車載機器にも適用可能であり、車両側の設置母材に対する取付強度が高く着脱作業に支障を来す虞もない車載機器の取付構造を提供することにある。   The present invention has been made in view of the situation of the prior art as described above, and the object thereof is applicable to in-vehicle devices having a short depth dimension. An object of the present invention is to provide an in-vehicle device mounting structure that does not cause any trouble.

上記の目的を達成するために、本発明は、車載機器のシャーシに保持されたロック部材が車両側の設置母材に掛止可能であると共に、取外し治具を用いて前記ロック部材の掛止状態を解除することによって、前記車載機器を前記設置部材から取り外すことが可能な車載機器の取付構造において、前記ロック部材を、前記車載機器の奥行き方向に対して直交する方向に延びる金属板製の板金スライダと、この板金スライダに圧縮状態で収納されたコイルばねとによって構成すると共に、前記板金スライダに、その長手方向の一端部にせり出す掛止部と、前記長手方向の他端部に延在して前記コイルばねを収納するばね収納部と、このばね収納部の長手方向他端部の終端を規定する抜け止め壁と、前記掛止部と前記ばね収納部とを連結する基部と、この基部内の空間と前記ばね収納部内の空間とを仕切る位置に存する隔壁とを折曲形成し、かつ、前記シャーシに、前記板金スライダを長手方向へスライド移動可能に位置規制するガイド部と、前記抜け止め壁に形成された隙間から前記ばね収納部に挿入されて前記コイルばねを前記隔壁へ向けて加圧するばね押え部とを折曲形成し、前記コイルばねが前記板金スライダを長手方向の一端側へ付勢して前記掛止部を前記シャーシの外方へ突出せしめることによって、前記掛止部を前記設置母材に掛止させてロック状態となし、前記コイルばねの付勢力に抗して前記取外し治具で前記板金スライダを長手方向の他端側へスライド移動させることによって、前記掛止部と前記設置母材のロック状態が解除されるようにした。 In order to achieve the above object, according to the present invention, a locking member held in a chassis of an in-vehicle device can be hooked on an installation base material on a vehicle side, and the locking member is hooked using a removing jig. In the in-vehicle device mounting structure in which the in-vehicle device can be removed from the installation member by releasing the state, the lock member is made of a metal plate extending in a direction orthogonal to the depth direction of the in-vehicle device. A sheet metal slider and a coil spring housed in a compressed state in the sheet metal slider are configured. The latch extends to one end in the longitudinal direction of the sheet metal slider and extends to the other end in the longitudinal direction. a spring housing part for to accommodating the coil spring, a base portion for connecting the retainer wall defining the end of the other longitudinal end of the spring storage portion, and said and said locking portion the spring housing portion And a partition wall existing in a position which divides the space between the space within the spring accommodating portion in this base and bent form, and, on the chassis, and a guide portion for slidably position regulating the sheet metal slider longitudinally, A spring holding part that is inserted into the spring housing part through the gap formed in the retaining wall and pressurizes the coil spring toward the partition wall is bent, and the coil spring pushes the sheet metal slider in the longitudinal direction. By urging to one end side and projecting the latching part outward of the chassis, the latching part is latched to the installation base material to be locked, and resists the biasing force of the coil spring. Then, by sliding the sheet metal slider to the other end side in the longitudinal direction with the removal jig, the locked state of the hooking portion and the installation base material is released.

このように板金スライダの掛止部をコイルばねの付勢力でシャーシの外方へ突出させて車両側の設置母材に掛止させるという取付構造を採用すると、コイルばねの付勢力を強くして設置母材に対する車載機器の取付強度を高めても、コイルばねは弾性変形させ易く塑性変形しにくい部品であるため、車載機器の着脱作業を円滑に行うことができる。また、板金スライダの長手方向は車載機器の奥行き方向に対して直交しているため、この取付構造は奥行き寸法の短い車載機器にも問題なく適用できる。しかも、１枚の金属板を折曲加工することで所要の機械的強度を有する板金スライダを形成でき、この板金スライダにコイルばねを組み込むだけでロック部材が得られると共に、シャーシの切り起こし片等によってガイド部やばね押え部を形成できるため、部品点数が少なく安価な取付構造を容易に実現することができる。   In this way, if the mounting structure is adopted in which the latching portion of the sheet metal slider is projected outward of the chassis by the biasing force of the coil spring and latched to the vehicle base material, the biasing force of the coil spring is increased. Even if the mounting strength of the in-vehicle device with respect to the installation base material is increased, the coil spring is a component that is easily elastically deformed and hardly plastically deformed, so that the in-vehicle device can be attached and detached smoothly. In addition, since the longitudinal direction of the sheet metal slider is orthogonal to the depth direction of the in-vehicle device, this mounting structure can be applied to the in-vehicle device having a short depth without problems. Moreover, a sheet metal slider having the required mechanical strength can be formed by bending a single metal plate, and a lock member can be obtained simply by incorporating a coil spring into the sheet metal slider, and a chassis cut-and-raised piece, etc. Since a guide part and a spring pressing part can be formed by this, an inexpensive mounting structure with a small number of parts can be easily realized.

上記の構成において、板金スライダに長手方向に沿って延びるフランジ部を折曲形成し、このフランジ部をシャーシのガイド部に摺接させることによって、板金スライダが長手方向と直交する幅方向に位置規制されるようにしてあると、板金スライダを長手方向に沿って円滑にスライド移動させ易くなるため好ましい。この場合において、板金スライダの基部が半角筒状に折曲形成されていると共に、一対のフランジ部が基部の底部に連続して折曲形成されていると、基部を支えるフランジ部をシャーシに摺動させながら板金スライダをスライド移動させることができるため、板金スライダにガタが生じにくくなって一層円滑なスライド移動を期待できる。しかも、基部に所要の機械的強度を確保しつつ１枚の金属板から板金スライダの展開形状を効率良く打ち抜くことができるため、材料の無駄を低減できる。   In the above configuration, the flange portion extending in the longitudinal direction is bent on the sheet metal slider, and the flange portion is slidably contacted with the guide portion of the chassis, so that the sheet metal slider is regulated in the width direction orthogonal to the longitudinal direction. This is preferable because the sheet metal slider can be easily slid smoothly along the longitudinal direction. In this case, when the base portion of the sheet metal slider is bent in a half-square tube shape and the pair of flange portions are continuously bent at the bottom portion of the base portion, the flange portion supporting the base portion is slid onto the chassis. Since the sheet metal slider can be slid while being moved, the sheet metal slider is less likely to be loose, and a smoother sliding movement can be expected. Moreover, since the developed shape of the sheet metal slider can be efficiently punched from one metal plate while ensuring the required mechanical strength at the base, waste of material can be reduced.

また、上記の構成において、板金スライダの基部とばね収納部は同径に形成されていても良いが、基部に比してばね収納部が低背に形成されていると共に、このばね収納部の内径がコイルばねの外径と略同等であると、ばね収納部によってコイルばねの径方向のガタを効果的に抑制できると共に、板金スライダの展開形状において基部とばね収納部間の段差に伴う余剰部分を利用して隔壁を形成できるため、材料の無駄をより効果的に低減できる。   In the above configuration, the base portion of the sheet metal slider and the spring storage portion may be formed to have the same diameter, but the spring storage portion is formed with a low profile as compared with the base portion. When the inner diameter is substantially the same as the outer diameter of the coil spring, the radial backlash of the coil spring can be effectively suppressed by the spring storage portion, and surplus due to a step between the base portion and the spring storage portion in the developed shape of the sheet metal slider Since a partition can be formed using a part, waste of material can be reduced more effectively.

また、上記の構成において、板金スライダの基部に取外し治具（リリースキー）を挿入するための挿入孔が開設されていると、機械的強度が確保し易い基部に取外し治具を確実に係合させることができるため、取外し治具を用いて板金スライダを所望方向へスライド移動させるロック解除作業を簡単かつ確実に行えるようになる。   In the above configuration, if the insertion hole for inserting the removal jig (release key) is opened in the base of the sheet metal slider, the removal jig is securely engaged with the base where mechanical strength is easy to secure. Therefore, the unlocking operation of sliding the sheet metal slider in the desired direction using the removal jig can be performed easily and reliably.

本発明の取付構造によれば、板金スライダにコイルばねを収納してなるロック部材を車載機器のシャーシにスライド移動可能に組み付け、コイルばねの付勢力で板金スライダの掛止部をシャーシの外方へ突出させて車両側の設置母材に掛止させることによって、車載機器が設置母材に取り付けられるようにしてあるため、コイルばねの付勢力を強くして設置母材に対する車載機器の取付強度を高めても、コイルばねは弾性変形させ易く塑性変形しにくい部品であるため車載機器の着脱作業を円滑に行うことができる。また、板金スライダの長手方向は車載機器の奥行き方向に対して直交しているため、この取付構造は奥行き寸法の短い車載機器にも問題なく適用できる。しかも、１枚の金属板を折曲加工することで所要の機械的強度を有する板金スライダを形成でき、この板金スライダにコイルばねを組み込むだけでロック部材が得られると共に、シャーシの切り起こし片等によってガイド部やばね押え部を形成できるため、部品点数が少なく安価な取付構造を容易に実現することができる。   According to the mounting structure of the present invention, a locking member that houses a coil spring in a sheet metal slider is slidably assembled to a chassis of an in-vehicle device, and the latching portion of the sheet metal slider is moved outwardly of the chassis by the biasing force of the coil spring. Since the in-vehicle device is attached to the installation base material by projecting to the installation base material on the vehicle side, the urging force of the coil spring is strengthened and the mounting strength of the in-vehicle device to the installation base material Even if the coil spring is increased, since the coil spring is a component that is easily elastically deformed and hardly plastically deformed, the mounting and dismounting operation of the in-vehicle device can be performed smoothly. In addition, since the longitudinal direction of the sheet metal slider is orthogonal to the depth direction of the in-vehicle device, this mounting structure can be applied to the in-vehicle device having a short depth without problems. Moreover, a sheet metal slider having the required mechanical strength can be formed by bending a single metal plate, and a lock member can be obtained simply by incorporating a coil spring into the sheet metal slider, and a chassis cut-and-raised piece, etc. Since a guide part and a spring pressing part can be formed by this, an inexpensive mounting structure with a small number of parts can be easily realized.

以下、本発明の実施形態例について図１〜図３９を参照しつつ説明する。これらの図に示す車載機器１は、カーナビゲーションやカーオーディオ等として多機能に使用できる電子機器である。図１〜図１４に示すように、この車載機器１は、表示部２０や複数の操作キー２１や回転操作ノブ２２，２３等を有する機器本体２と、機器本体２の背面２ａに固定されたシャーシ３と、シャーシ３にスライド移動可能に保持された一対のロック部材４とによって主に構成されている。図１６や図１７に示すように、通常、この車載機器１は車両側の設置母材（インストルメントパネル）１０に取り付けられているが、外部機器と接続したい場合や修理したい場合等には、図３９に示すように、車載機器１を設置母材１０から取り外すことができるようになっている。そして、取り外した車載機器１を手持ちのビデオカメラやゲーム機等の外部機器と接続することにより、この車載機器１の表示部２０や内蔵スピーカを利用して外部機器の映像や音声の情報が視聴できるようになっている。   Embodiments of the present invention will be described below with reference to FIGS. The in-vehicle device 1 shown in these drawings is an electronic device that can be used for multiple functions, such as car navigation and car audio. As shown in FIGS. 1 to 14, the in-vehicle device 1 is fixed to a device main body 2 having a display unit 20, a plurality of operation keys 21, rotary operation knobs 22 and 23, and a back surface 2 a of the device main body 2. It is mainly constituted by the chassis 3 and a pair of lock members 4 held slidably by the chassis 3. As shown in FIG. 16 and FIG. 17, the in-vehicle device 1 is usually attached to a vehicle-side installation base material (instrument panel) 10, but when connecting to an external device or repairing, As shown in FIG. 39, the in-vehicle device 1 can be detached from the installation base material 10. Then, by connecting the removed in-vehicle device 1 to an external device such as a video camera or game machine on hand, the video or audio information of the external device can be viewed using the display unit 20 or the built-in speaker of the in-vehicle device 1. It can be done.

この車載機器１が車両側の設置母材１０に取り付けられているときには、図１７に示すように、ロック部材４を構成する板金スライダ５の掛止部５１がシャーシ３の外方へ突出して設置母材１０の係合突起部１１に掛止されている。図１８〜図２６に示すように、板金スライダ５は圧縮状態のコイルばね６を収納しており、このコイルばね６の付勢力によって掛止部５１をシャーシ３の外方へ押し出す向きに板金スライダ５が付勢されている。また、図３４〜図３８に示すように、取外し治具であるリリースキー７を機器本体２のキー挿入用スロット２ｂを介して板金スライダ５の挿入孔５２へ挿入することにより、この板金スライダ５をコイルばね６の付勢力に抗してスライド移動させることができる。これにより、掛止部５１を設置母材１０の係合突起部１１から離脱させることができるため、車載機器１を手前へ引っ張れば、図３９に示すように設置母材１０から車載機器１が取り外せるようになっている。   When the in-vehicle device 1 is attached to the vehicle-side installation base material 10, as shown in FIG. 17, the latching portion 51 of the sheet metal slider 5 constituting the lock member 4 protrudes outward from the chassis 3. It is hooked on the engaging projection 11 of the base material 10. As shown in FIGS. 18 to 26, the sheet metal slider 5 houses a coil spring 6 in a compressed state, and the urging force of the coil spring 6 pushes the latching portion 51 outward of the chassis 3. 5 is energized. Further, as shown in FIGS. 34 to 38, the release key 7 as a removal jig is inserted into the insertion hole 52 of the sheet metal slider 5 through the key insertion slot 2 b of the apparatus main body 2. Can be slid against the biasing force of the coil spring 6. Thereby, since the latching | locking part 51 can be made to detach | leave from the engagement protrusion part 11 of the installation base material 10, if the vehicle equipment 1 is pulled forward, the vehicle equipment 1 will be removed from the installation base material 10 as shown in FIG. It can be removed.

ロック部材４について詳しく説明すると、図２や図３に示すように、このロック部材４はシャーシ３内の右下隅部と左下隅部に保持されている。各ロック部材４は、金属板を折曲加工してなる板金スライダ５と、この板金スライダ５のばね収納部５３内に圧縮状態で収納されたコイルばね６とによって構成されている。板金スライダ５は車載機器１の奥行き方向に対して直交する左右方向に延びており、コイルばね６の軸線方向も板金スライダ５の長手方向と同じ向きである。また、シャーシ３の背面板３０にガイド部３１と規制部３２とばね押え部３３が折曲形成されており、そのうちガイド部３１と規制部３２が板金スライダ５を長手方向へスライド移動できるように支持しており、ばね押え部３３が板金スライダ５内へ遊挿されてコイルばね６の一方の受け部として機能するようになっている。ただし、各ロック部材４は全く同等のものであり、シャーシ３内に一方のロック部材４が右向きに組み込まれ他方のロック部材４が左向きに組み込まれている。また、シャーシ３の右下隅部と左下隅部に設けられているロック部材４用の支持構造（ガイド部３１や規制部３２、ばね押え部３３等）も全く同じものである。   The lock member 4 will be described in detail. As shown in FIGS. 2 and 3, the lock member 4 is held at the lower right corner and the lower left corner in the chassis 3. Each lock member 4 includes a sheet metal slider 5 formed by bending a metal plate and a coil spring 6 accommodated in a compressed state in a spring accommodating portion 53 of the sheet metal slider 5. The sheet metal slider 5 extends in the left-right direction orthogonal to the depth direction of the in-vehicle device 1, and the axial direction of the coil spring 6 is the same as the longitudinal direction of the sheet metal slider 5. Further, a guide portion 31, a restriction portion 32, and a spring retainer portion 33 are formed on the back plate 30 of the chassis 3 so that the guide portion 31 and the restriction portion 32 can slide the sheet metal slider 5 in the longitudinal direction. The spring pressing portion 33 is loosely inserted into the sheet metal slider 5 and functions as one receiving portion of the coil spring 6. However, the lock members 4 are completely equivalent, and one lock member 4 is incorporated in the chassis 3 in the right direction and the other lock member 4 is incorporated in the left direction. Further, the support structures for the lock member 4 (the guide portion 31, the restricting portion 32, the spring pressing portion 33, etc.) provided at the lower right corner and the lower left corner of the chassis 3 are exactly the same.

図１８〜図２６はロック部材４の外観を示しており、図２８〜図３３は板金スライダ５の外観を示している。これらの図に示すように、板金スライダ５は、長手方向の一端部にせり出す掛止部５１と、長手方向の他端部に延在してコイルばね６を収納するばね収納部５３と、このばね収納部５３の終端を規定する抜け止め壁５４と、掛止部５１とばね収納部５３とを連結する半角筒状の基部５５と、この基部５５から舌片状に延出する隔壁５６と、基部５５を支える脚片として該基部５５の底部に長手方向に沿って延在する一対のフランジ部５７とによって主に構成されている。ばね収納部５３の内径はコイルばね６の外径と略同等に設定されているため、基部５５に比してばね収納部５３は低背であり、両者５５，５３間には段差が形成されている。隔壁５６は基部５５内の空間とばね収納部５３内の空間とを仕切る位置に配置されており、この隔壁５６がコイルばね６の他方の受け部として機能するため、コイルばね６は隔壁５６に常時弾接している。   18 to 26 show the appearance of the lock member 4, and FIGS. 28 to 33 show the appearance of the sheet metal slider 5. As shown in these drawings, the sheet metal slider 5 includes a latching portion 51 protruding to one end portion in the longitudinal direction, a spring housing portion 53 extending to the other end portion in the longitudinal direction and housing the coil spring 6, A retaining wall 54 that defines the terminal end of the spring storage portion 53, a half-tube-shaped base portion 55 that connects the latch portion 51 and the spring storage portion 53, and a partition wall 56 that extends from the base portion 55 in a tongue-like shape. As a leg piece for supporting the base 55, the base 55 is mainly constituted by a pair of flange portions 57 extending along the longitudinal direction at the bottom of the base 55. Since the inner diameter of the spring accommodating portion 53 is set to be substantially equal to the outer diameter of the coil spring 6, the spring accommodating portion 53 has a low profile as compared with the base portion 55, and a step is formed between the both 55 and 53. ing. The partition wall 56 is disposed at a position for partitioning the space in the base portion 55 and the space in the spring storage portion 53, and this partition wall 56 functions as the other receiving portion of the coil spring 6. Always in contact.

かかる板金スライダ５は、図２７に示す展開形状の１枚の金属板を折り曲げて形成したものである。掛止部５１は一対の傾斜したＬ字片として折曲形成されており、この掛止部５１の傾斜面５１ａは設置母材１０の係合突起部１１との係脱が円滑に行えるようにするため微細な階段形状に打ち抜かれている。基部５５は板金スライダ５の本体部分として機械的強度に富む半角筒状に折曲形成されており、この基部５５の天板部の所定位置にリリースキー７を挿入させるための挿入孔５２が開設されている。フランジ部５７は基部５５の全長部分だけでなくばね収納部５３の途中まで延びており、このフランジ部５７の長手方向に沿う側縁がシャーシ３のガイド部３１に摺接して位置規制されるようになっている。また、各フランジ部５７の長手方向の一端部にはシャーシ３の側板３４に当接する幅広なストッパ部５８が形成されている。抜け止め壁５４はばね収納部５３の側板部に連続する一対の折曲片として形成されており、両折曲片の間の隙間５４ａにシャーシ３のばね押え部３３が遊挿されるようになっている。なお、基部５５の側板部に形成した切り起こし部５５ａは隔壁５６を基部５５側から補強している。また、組立工程でコイルばね６がばね収納部５３内から脱落しないようにするため、ばね収納部５３の側板部には絞り加工によって内方へ突出する突条部５３ａが形成されている。   The sheet metal slider 5 is formed by bending a single metal plate having a developed shape shown in FIG. The latching portion 51 is bent as a pair of inclined L-shaped pieces, and the inclined surface 51a of the latching portion 51 can smoothly engage and disengage with the engaging projection 11 of the installation base material 10. Therefore, it is punched into a fine staircase shape. The base 55 is bent as a main body portion of the sheet metal slider 5 in the shape of a half-square cylinder having high mechanical strength, and an insertion hole 52 for inserting the release key 7 is opened at a predetermined position of the top plate of the base 55. Has been. The flange portion 57 extends not only to the full length portion of the base portion 55 but also to the middle of the spring accommodating portion 53, and the side edge along the longitudinal direction of the flange portion 57 is slidably contacted with the guide portion 31 of the chassis 3 so that the position is regulated. It has become. In addition, a wide stopper portion 58 that abuts against the side plate 34 of the chassis 3 is formed at one end portion of each flange portion 57 in the longitudinal direction. The retaining wall 54 is formed as a pair of bent pieces continuous with the side plate portion of the spring accommodating portion 53, and the spring pressing portion 33 of the chassis 3 is loosely inserted into the gap 54a between the bent pieces. ing. The cut-and-raised portion 55a formed on the side plate portion of the base portion 55 reinforces the partition wall 56 from the base portion 55 side. Further, in order to prevent the coil spring 6 from falling out of the spring accommodating portion 53 in the assembling process, the side plate portion of the spring accommodating portion 53 is formed with a protrusion 53a that protrudes inward by drawing.

図２，３と図５〜図８に示すように、シャーシ３の背面板３０には各ロック部材４に対応して、左右方向へ延びる直線状のガイド部３１が一対ずつ設けられていると共に、各ガイド部３１の長手方向の両端近傍にそれぞれ規制部３２が設けられている。ガイド部３１は帯状の切り起こし片に絞り加工を施して形成されており、板金スライダ５の両側面に沿って延在する一対のフランジ部５７が一対のガイド部３１に摺接するようにしてあるため、これらガイド部３１によって板金スライダ５は幅方向に位置規制されて長手方向へスライド移動可能に案内されている。各規制部３２は矩形状の切り起こし片に段曲げを加工を施して形成されており、これら規制部３２でフランジ部５７を板厚方向に位置規制することによって、板金スライダ５が背面板３０に対してガタを生じないようにしてある。また、背面板３０には各ロック部材４のばね収納部５３が配置される領域にそれぞればね押え部３３が直角に切り起こされている。この押え部３３は板金スライダ５の抜け止め壁５４の隙間５４ａを介してばね収納部５３内へ挿入されるため、コイルばね６を隔壁５６へ向けて常時加圧する。 As shown in FIGS. 2 and 3 and FIGS. 5 to 8, the back plate 30 of the chassis 3 is provided with a pair of linear guide portions 31 extending in the left-right direction corresponding to each lock member 4. The restricting portions 32 are provided in the vicinity of both ends in the longitudinal direction of each guide portion 31. The guide portion 31 is formed by drawing a strip-like cut and raised piece, and a pair of flange portions 57 extending along both side surfaces of the sheet metal slider 5 are in sliding contact with the pair of guide portions 31. Therefore, the sheet metal slider 5 is guided by the guide portions 31 so as to be slidable in the longitudinal direction while being regulated in the width direction. Each restricting portion 32 is formed by subjecting a rectangular cut and raised piece to step bending. By restricting the flange portion 57 in the plate thickness direction with these restricting portions 32, the sheet metal slider 5 is moved to the back plate 30. Against the backlash. Further, on the back plate 30, spring pressing portions 33 are cut and raised at right angles in regions where the spring accommodating portions 53 of the respective lock members 4 are arranged. Since the pressing portion 33 is inserted into the spring accommodating portion 53 through the gap 54 a of the retaining wall 54 of the sheet metal slider 5, the pressing portion 33 constantly pressurizes the coil spring 6 toward the partition wall 56.

すなわち、ロック部材４をシャーシ３に組み付けると、ガイド部３１および規制部３２によって板金スライダ５は長手方向にスライド移動可能に支持されるが、ばね押え部３３がコイルばね６を加圧するため、コイルばね６の付勢力が隔壁５６に付与される。それゆえ、図２や図３に示すように、板金スライダ５は長手方向の一端側（掛止部５１側）へ付勢され、それに伴ってストッパ部５８が側板３４に当接した状態に保持されると共に、掛止部５１が側板３４の開口部３４ａから外方へ突出した状態となる。   That is, when the lock member 4 is assembled to the chassis 3, the sheet metal slider 5 is supported by the guide portion 31 and the restriction portion 32 so as to be slidable in the longitudinal direction, but the spring retainer 33 pressurizes the coil spring 6, The biasing force of the spring 6 is applied to the partition wall 56. Therefore, as shown in FIGS. 2 and 3, the sheet metal slider 5 is urged toward one end side in the longitudinal direction (the latching portion 51 side), and accordingly, the stopper portion 58 is held in contact with the side plate 34. At the same time, the latching portion 51 protrudes outward from the opening 34 a of the side plate 34.

こうしてロック部材４を組み付けたシャーシ３は、図５や図７に示すように、固定ねじ８等を用いて機器本体２の背面２ａに固定されるため、車載機器１の背面側の左右両側部には板金スライダ５の掛止部５１が露出して外方へ突き出ている。そして、この車載機器１が車両側の設置母材（インストルメントパネル）１０に取り付けられると、図１７に示すように、掛止部５１が設置母材１０の係合突起部１１に掛止されてロック状態となるため、車載機器１は設置母材１０に対して抜け止め状態で装着される（図１６参照）。   As shown in FIGS. 5 and 7, the chassis 3 assembled with the lock member 4 is fixed to the back surface 2 a of the device main body 2 using a fixing screw 8 or the like. The latching portion 51 of the sheet metal slider 5 is exposed and protrudes outward. Then, when the in-vehicle device 1 is attached to the installation base material (instrument panel) 10 on the vehicle side, as shown in FIG. 17, the latching portion 51 is latched on the engagement protrusion 11 of the installation base material 10. Therefore, the in-vehicle device 1 is attached to the installation base material 10 in a retaining state (see FIG. 16).

また、車両側に装着されている車載機器１を修理したり外部機器と接続するために設置母材１０から取り外す際には、まず、図３４〜図３６に示すように、リリースキー７を機器本体２のキー挿入用スロット２ｂに差し込むことによって、リリースキー７の楔状先部７ａを板金スライダ５の挿入孔５２に挿入する。なお、本実施形態例では、左右の上隅部に取り付けられている操作キー２１を外すことによってキー挿入用スロット２ｂが露出するようになっている（図１５参照）。キー挿入用スロット２ｂに差し込んだリリースキー７を作業者が挿入方向へ押し込んでいくと、リリースキー７の楔状先部７ａがコイルばね６の付勢力に抗して板金スライダ５をばね押え部３３側へスライド移動させていくため、板金スライダ５の掛止部５１が徐々にシャーシ３内へ後退していく。そして、リリースキー７が図３７に示す位置まで挿入されると、掛止部５１はシャーシ３内へほとんど没入するため、この掛止部５１は設置母材１０の係合突起部１１から離脱して掛止状態（ロック状態）が解除される。車載機器１のシャーシ３にはロック部材４が左右２個所に組み付けられているので、各ロック部材４の板金スライダ５をそれぞれリリースキー７でスライド移動させて係合突起部１１から離脱させれば、この車載機器１は設置母材１０に拘持されないロック解除状態となる。それゆえ、図３８に示すように各リリースキー７を挿入可能な最奥まで押し込んで対応する板金スライダ５に係着させてから、作業者が車載機器１を手前へ引っ張れば、図３９に示すように車載機器１を設置母材１０から取り外すことができる。   When the vehicle-mounted device 1 mounted on the vehicle side is removed from the installation base material 10 in order to repair or connect to an external device, first, as shown in FIGS. The wedge-shaped tip 7 a of the release key 7 is inserted into the insertion hole 52 of the sheet metal slider 5 by being inserted into the key insertion slot 2 b of the main body 2. In this embodiment, the key insertion slot 2b is exposed by removing the operation key 21 attached to the upper left and right corners (see FIG. 15). When the operator pushes the release key 7 inserted into the key insertion slot 2b in the insertion direction, the wedge-shaped tip portion 7a of the release key 7 resists the urging force of the coil spring 6 to hold the sheet metal slider 5 to the spring pressing portion 33. The latching portion 51 of the sheet metal slider 5 is gradually retracted into the chassis 3 in order to be slid to the side. When the release key 7 is inserted to the position shown in FIG. 37, the latching portion 51 is almost immersed into the chassis 3, so that the latching portion 51 is detached from the engagement protrusion 11 of the installation base material 10. The locked state (locked state) is released. Since the locking member 4 is assembled to the left and right two places on the chassis 3 of the in-vehicle device 1, if the sheet metal slider 5 of each locking member 4 is slid with the release key 7 and separated from the engaging protrusion 11. The in-vehicle device 1 is in an unlocked state that is not held by the installation base material 10. Therefore, as shown in FIG. 38, when each release key 7 is pushed to the innermost position where it can be inserted and engaged with the corresponding sheet metal slider 5, the operator pulls the vehicle-mounted device 1 forward, as shown in FIG. Thus, the in-vehicle device 1 can be detached from the installation base material 10.

以上説明したように、本実施形態例においては、板金スライダ５にコイルばね６を収納してなるロック部材４を車載機器１のシャーシ３にスライド移動可能に組み付け、コイルばね６の付勢力で板金スライダ５の掛止部５１をシャーシ３の外方へ突出させて車両側の設置母材１０に掛止させることによって、車載機器１が設置母材１０に取り付けられるようにしてある。そのため、コイルばね６の付勢力を強くして設置母材１０に対する車載機器１の取付強度を高めても、コイルばね６は弾性変形させ易く塑性変形しにくい部品であるため、車載機器１の着脱作業を円滑に行うことができる。また、板金スライダ５の長手方向は車載機器１の奥行き方向に対して直交しているため、本実施形態例に係る取付構造は奥行き寸法の短い薄型の車載機器１にも問題なく適用できる。ただし、車載機器１が奥行寸法の長い厚型のものであったとしても、同様の取付構造を適用できることは言うまでもない。   As described above, in the present embodiment, the lock member 4 in which the coil spring 6 is housed in the sheet metal slider 5 is assembled to the chassis 3 of the in-vehicle device 1 so as to be slidable. The in-vehicle device 1 is attached to the installation base material 10 by projecting the latching portion 51 of the slider 5 to the outside of the chassis 3 and engaging the installation base material 10 on the vehicle side. For this reason, even if the urging force of the coil spring 6 is increased to increase the mounting strength of the in-vehicle device 1 with respect to the installation base material 10, the coil spring 6 is a component that is easily elastically deformed and hardly plastically deformed. Work can be performed smoothly. Further, since the longitudinal direction of the sheet metal slider 5 is orthogonal to the depth direction of the in-vehicle device 1, the mounting structure according to this embodiment can be applied to the thin in-vehicle device 1 having a short depth dimension without any problem. However, it goes without saying that the same mounting structure can be applied even if the in-vehicle device 1 is a thick type having a long depth dimension.

また、本実施形態例においては、１枚の金属板を折曲加工することで所要の機械的強度を有する板金スライダ５が形成でき、この板金スライダ５にコイルばね６を組み込むだけでロック部材４が得られると共に、シャーシ３の切り起こし片等によってガイド部３１や規制部３２やばね押え部３３等が形成できるため、部品点数が少なくて安価な取付構造となっている。   Further, in the present embodiment, a sheet metal slider 5 having a required mechanical strength can be formed by bending a single metal plate, and the lock member 4 can be formed simply by incorporating the coil spring 6 into the sheet metal slider 5. In addition, since the guide part 31, the restricting part 32, the spring pressing part 33, and the like can be formed by the cut and raised pieces of the chassis 3, the number of parts is small and the mounting structure is inexpensive.

また、本実施形態例においては、板金スライダ５に長手方向に沿って延びるフランジ部５７が折曲形成されており、このフランジ部５７をシャーシ３のガイド部３１に摺接させることによって、板金スライダ５が長手方向と直交する幅方向に位置規制されるようにしてあるため、板金スライダ５を長手方向に沿って円滑にスライド移動させ易くなっている。しかも、板金スライダ５の基部５５が半角筒状に折曲形成されていると共に、この基部５５を支える脚片として一対のフランジ部５７が該基部５５の底部に連続して折曲形成されているため、基部５５を支えるフランジ部５７をシャーシ３に摺動させながら板金スライダ５をガタなく円滑にスライド移動させることができる。さらに、基部５５に所要の機械的強度を確保しつつ１枚の金属板から板金スライダ５の展開形状を効率良く打ち抜くことができるため、材料の無駄を低減できる。ただし、基部５５を筒状に形成して機械的強度をさらに高めた板金スライダ５を用いることも可能である。   Further, in the present embodiment, a flange portion 57 extending in the longitudinal direction is formed on the sheet metal slider 5 in a bent manner, and the flange portion 57 is brought into sliding contact with the guide portion 31 of the chassis 3 to thereby make the sheet metal slider. Since the position of 5 is regulated in the width direction orthogonal to the longitudinal direction, the sheet metal slider 5 can be easily slid smoothly along the longitudinal direction. In addition, the base portion 55 of the sheet metal slider 5 is bent in a half-square tube shape, and a pair of flange portions 57 are continuously bent at the bottom portion of the base portion 55 as leg pieces for supporting the base portion 55. Therefore, the sheet metal slider 5 can be smoothly slid and moved without sliding while the flange portion 57 supporting the base portion 55 is slid on the chassis 3. Furthermore, since the developed shape of the sheet metal slider 5 can be efficiently punched from one metal plate while ensuring the required mechanical strength at the base 55, waste of material can be reduced. However, it is also possible to use the sheet metal slider 5 in which the base portion 55 is formed in a cylindrical shape to further increase the mechanical strength.

また、本実施形態例においては、板金スライダ５のばね収納部５３の内径がコイルばね６の外径と略同等に設定されており、このばね収納部５３が基部５５に比して低背であって両者５３，５５間に段差が形成されている。そのため、ばね収納部５３によってコイルばね６の径方向のガタを効果的に抑制できると共に、基部５５から舌片状に延出する隔壁５６を効率良く形成できるようになっている。つまり、板金スライダ５の展開形状において基部５５とばね収納部５３間の段差に伴う余剰部分を利用して隔壁５６を形成できるため、材料の無駄がより効果的に低減できる。ただし、使用するコイルばね６の材料や外径等を適宜選択すれば、基部５５とばね収納部５３とが同径で両者５５，５３間に段差のない形状の板金スライダ５を用いることも可能である。   In this embodiment, the inner diameter of the spring accommodating portion 53 of the sheet metal slider 5 is set to be substantially equal to the outer diameter of the coil spring 6, and the spring accommodating portion 53 has a lower height than the base portion 55. Therefore, a step is formed between the two 53 and 55. Therefore, the backlash in the radial direction of the coil spring 6 can be effectively suppressed by the spring accommodating portion 53, and the partition wall 56 extending in a tongue shape from the base portion 55 can be efficiently formed. That is, since the partition wall 56 can be formed using the surplus portion associated with the step between the base 55 and the spring storage portion 53 in the developed shape of the sheet metal slider 5, waste of material can be more effectively reduced. However, if the material, outer diameter, etc. of the coil spring 6 to be used are appropriately selected, it is possible to use the sheet metal slider 5 having a shape in which the base portion 55 and the spring storage portion 53 have the same diameter and no step between the two portions 55 and 53. It is.

また、本実施形態例においては、板金スライダ５の基部５５にリリースキー７を挿入するための挿入孔５２が開設されているため、機械的強度が確保し易い基部５５にリリースキー７を確実に係合させることができ、それゆえ、リリースキー７を用いて板金スライダ５を所望方向へスライド移動させるロック解除（掛止解除）作業を簡単かつ確実に行えるようになっている。   In this embodiment, since the insertion hole 52 for inserting the release key 7 is opened in the base portion 55 of the sheet metal slider 5, the release key 7 is securely attached to the base portion 55 where mechanical strength is easily secured. Therefore, the unlocking (latching release) operation of sliding the sheet metal slider 5 in the desired direction using the release key 7 can be performed easily and reliably.
