Description

本発明は、車両のテールゲート、テールハッチ等、車両の開口部に開閉自在に設けられる開閉扉体等の回動角度を一定位置で停止させる車両の開閉部保持機構に関し、特に、開閉力をアシストするコイルスプリング部材が用いられる車両の開閉部保持機構に関するものである。   The present invention relates to a vehicle opening / closing portion holding mechanism for stopping a rotation angle of an opening / closing door body or the like provided in an opening portion of a vehicle such as a tailgate and a tail hatch of a vehicle at a fixed position, and in particular, an opening / closing force. The present invention relates to an opening / closing part holding mechanism for a vehicle in which an assisting coil spring member is used.

従来の車両の開閉部保持機構としては、図１５及び図１６に示すようなものが知られている（例えば、特許文献１等参照）。   As a conventional vehicle opening / closing part holding mechanism, those shown in FIGS. 15 and 16 are known (see, for example, Patent Document 1).

まず、構成から説明すると、この従来の車両の開閉部保持機構では、図１５に示すように、ピックアップトラック等の車両１の後部２には、荷台３が設けられている。   First, in terms of configuration, in this conventional vehicle opening / closing part holding mechanism, as shown in FIG. 15, a loading platform 3 is provided at the rear part 2 of the vehicle 1 such as a pickup truck.

この荷台３の後端には、下縁部５ａ両端縁に水平方向に沿って形成された回動ヒンジ軸４，４を回動中心として、車両後方へ上縁部５ｂを回動させることにより、ゲートを開放させるテールゲート部材５が枢着されている。   At the rear end of the cargo bed 3, the upper edge portion 5b is rotated to the rear of the vehicle with the rotation hinge shafts 4 and 4 formed along the horizontal direction at both ends of the lower edge portion 5a as the rotation center. A tailgate member 5 for opening the gate is pivotally attached.

このテールゲート部材５には、左，右側縁部５ｃ，５ｃと、前記荷台３の側面部材３ａ，３ａの内側に固着される後部ストッパ部材３ｂ，３ｂとの間を連結する一対のゲートバランス装置７，７が設けられている。   The tail gate member 5 includes a pair of gate balance devices that connect the left and right edge portions 5c and 5c and the rear stopper members 3b and 3b fixed to the inside of the side members 3a and 3a of the cargo bed 3. 7,7 are provided.

このゲートバランス装置７は、図１６に示すように、中空円筒状の外筒部材７ｂと、この外筒部材７ｂの内側にスライド自在に挿抜される中空円筒状の内筒部材７ｃとを有して、両端が略閉塞されたシリンダ状の外形を呈している。   As shown in FIG. 16, the gate balance device 7 includes a hollow cylindrical outer cylinder member 7b, and a hollow cylindrical inner cylinder member 7c that is slidably inserted into and removed from the inner cylindrical member 7b. Thus, it has a cylindrical outer shape that is substantially closed at both ends.

この外筒部材７ｂ，及び内筒部材７ｃの内部には、前記左，右側縁部５ｃ，５ｃ及び後部ストッパ部材３ｂ，３ｂに固着される両端軸部７ａ，７ａ間に張設されて、伸縮弾性変形することにより、前記テールゲート部材５の開閉動作に必要とされる力をアシストするコイルスプリング部材８と、このコイルスプリング部材８の内側に位置して、前記荷台３の上面部３ｃと、開放されたテールゲート部材５の内側面５ｄとの間を略面一として、水平状態で停止させるベルト状の保持ロープ部材９とが設けられている。   The outer cylinder member 7b and the inner cylinder member 7c are stretched between the shaft portions 7a and 7a fixed to the left and right edge portions 5c and 5c and the rear stopper members 3b and 3b so as to expand and contract. A coil spring member 8 that assists a force required for the opening and closing operation of the tailgate member 5 by being elastically deformed; and an upper surface portion 3c of the cargo bed 3 that is positioned inside the coil spring member 8; A belt-like holding rope member 9 that stops in a horizontal state is provided so as to be substantially flush with the inner surface 5d of the opened tailgate member 5.

次に、この車両の開閉部保持機構の作用効果について説明する。   Next, the effect of the opening / closing part holding mechanism of the vehicle will be described.

これらの開閉体側折り返しループ部２４ｃ及び車体側折り返しループ部２４ｄとは、各々前記ゲート側支持軸固定ブラケット１５の開閉体側支持軸１７及び、前記車体側支持軸固定ブラケット１４の車体側支持軸１６との各外周面に、捲き付けられて折り返されることにより、前記２本の保持ロープ２４ａ，２４ａが並設されて、この保持ロープ部材２４全体がループ状を呈して係止されている。   The opening / closing body side folding loop portion 24c and the vehicle body side folding loop portion 24d are respectively the opening / closing body side support shaft 17 of the gate side support shaft fixing bracket 15 and the vehicle body side support shaft 16 of the vehicle body side support shaft fixing bracket 14. The two holding ropes 24a and 24a are juxtaposed to each other on the outer peripheral surfaces of the two, and the entire holding rope member 24 is locked in a loop shape.

そして、図１中実線で示す様に、前記テールゲート部材５の開放により、前記コイルスプリング部材２１が伸張される最大長さは、図４中二点鎖線で示すように、前記テールゲート５が、略水平状態となり、前記荷台３の上面部３ｃと、内側面５ｄとが略面一となる位置での前記開閉体側支持軸１７及び、前記車体側支持軸１６との間の寸法Ｌ２に適合されて設定されている。   As shown by a solid line in FIG. 1, the maximum length of the coil spring member 21 that is extended by opening the tail gate member 5 is as follows. As shown by a two-dot chain line in FIG. In accordance with the dimension L2 between the opening / closing body side support shaft 17 and the vehicle body side support shaft 16 at a position where the upper surface portion 3c of the cargo bed 3 and the inner side surface 5d are substantially flush with each other. Has been set.

すなわち、保持ロープ部材２４が、所定量延びきった状態で、前記テールゲート５の最大開放量となるように、予め設定することにより、前記荷台３の上面部３ｃと、開放されたテールゲート部材５の内側面５ｄとの間が略面一となる水平状態で停止され、更なるコイル部２１ａの伸張方向への変形が規制されるように構成されている。   That is, the upper surface portion 3c of the cargo bed 3 and the opened tailgate member are preset by setting the holding rope member 24 so as to reach the maximum opening amount of the tailgate 5 in a state where the holding rope member is fully extended by a predetermined amount. 5 is stopped in a horizontal state that is substantially flush with the inner side surface 5d, and further deformation of the coil portion 21a in the extending direction is restricted.

更に、この実施の形態では、図８に示すように、前記保持ロープ部材２４の長手方向略中央で、並設配置される一対、二本の前記保持ロープ２４ａ，２４ａ間の一部に、貼合固定部２５が設けられていて、側面視略８の字状を呈している。   Furthermore, in this embodiment, as shown in FIG. 8, the holding rope member 24 is attached to a part between the pair of holding ropes 24a, 24a arranged in parallel at the approximate center in the longitudinal direction. A joint fixing portion 25 is provided and has a shape of approximately 8 in side view.

この貼合固定部２５は、略全幅Ｗ１に渡り、糸２７…により、縫合されて固着されていて、各保持ロープ２４ａ，２４ａの両側縁部が一致するように、重複された状態で固定されている。   The bonding fixing portion 25 is fixed by being overlapped so that both side edges of the holding ropes 24a and 24a coincide with each other by being sewn and fixed by a thread 27 over substantially the entire width W1. ing.

また、この実施の形態では、図４中に示すように、前記コイルスプリング部材２１が伸張された状態で、コイル部２１ａの内側に位置する前記保持ロープ部材２４が、延びきると、貼合固定部２５の面内，外方向中心が、径方向ｄで、中心に位置するように構成されている。   Further, in this embodiment, as shown in FIG. 4, when the holding rope member 24 located inside the coil portion 21a is fully extended in a state where the coil spring member 21 is extended, the bonding fixing portion The in-plane and out-of-plane centers of 25 are configured to be located in the center in the radial direction d.

次に、この実施の形態の車両の開閉部保持機構の作用効果について、説明する。   Next, the effect of the opening / closing part holding mechanism for a vehicle according to this embodiment will be described.

この実施の形態の車両の開閉部保持機構では、ピックアップトラック１１の荷台３の後部１２に開口形成された開口部周縁１２ａのうち、下側周縁に沿って設けられた前記回動ヒンジ軸４を回動中心として、図１中白抜き矢印に示すように、前記テールゲート部材５が、上縁部５ｂを車両前後方向に揺動させながら開閉塞される。   In the opening / closing part holding mechanism of the vehicle of this embodiment, the rotating hinge shaft 4 provided along the lower peripheral edge of the opening peripheral edge 12a formed in the rear part 12 of the loading platform 3 of the pickup truck 11 is provided. As indicated by the white arrow in FIG. 1, the tailgate member 5 is opened and closed while swinging the upper edge portion 5b in the vehicle front-rear direction, as indicated by the white arrow in FIG.

この実施の形態では、前記保持ロープ部材２４の伸張方向である長手方向略中心位置で、略ループ状折り返されて、並設配置される二本の前記保持ロープ２４ａ，２４ａ間が、貼合固定部２５の糸２７…によって、縫合されて固定されている。   In this embodiment, between the two holding ropes 24a, 24a that are folded back in a substantially loop shape and arranged in parallel at the substantially central position in the longitudinal direction, which is the extension direction of the holding rope member 24, is bonded and fixed. It is sewn and fixed by the threads 27 of the portion 25.

このため、前記テールゲート部材５が、図１中二点鎖線で示すように、閉塞されると、前記コイルスプリング部材２１のコイル部２１ａが縮むと共に、前記保持ロープ２４ａ，２４ａが、二本同時に寄り添いながら、同方向へ上，下交互に撓み、前記車体側支持軸１６及び開閉体側支持軸１７間の寸法が短縮される。   Therefore, when the tailgate member 5 is closed as shown by a two-dot chain line in FIG. 1, the coil portion 21a of the coil spring member 21 is contracted and the holding ropes 24a and 24a are simultaneously two. While nestling, it bends up and down alternately in the same direction, and the dimension between the vehicle body side support shaft 16 and the opening / closing body side support shaft 17 is shortened.

このため、前記保持ロープ部材２４は、例えば、図１６に示す１本づつの保持ロープ９ａの曲げ剛性に比して、二本の保持ロープ２４ａ，２４ａが重合された保持ロープ部材２４は、略二倍の曲げ剛性を有する。   Therefore, for example, the holding rope member 24 in which the two holding ropes 24a and 24a are superposed is approximately compared to the bending rigidity of the holding ropes 9a shown in FIG. Has double bending stiffness.

従って、従来のように、保持ロープ９ａ個別に撓む場合に比して、図５に示すように、緩やかな曲率で蛇行して、前記コイルスプリング部材２１のコイル部２１ａの隣接するコイル間に、前記保持ロープ２４ａが、個別に噛み込まれる虞を減少させることができる。   Therefore, compared to the case where the holding ropes 9a are individually bent as in the prior art, as shown in FIG. 5, the meandering is performed with a gentle curvature between adjacent coils of the coil portion 21a of the coil spring member 21. The possibility that the holding rope 24a is individually bitten can be reduced.

従って、前記テールゲート部材５による荷台３の後部１２の閉塞を良好に行うことができる。   Therefore, the rear portion 12 of the loading platform 3 can be satisfactorily closed by the tailgate member 5.

また、この実施の形態では、前記コイルスプリング部材２１のコイル部２１ａの内側に位置する前記保持ロープ部材２４の貼合固定部２５が、図４中に示すように、径方向ｄで、中心に位置するように構成されている。   Moreover, in this embodiment, the bonding fixing part 25 of the holding rope member 24 located inside the coil part 21a of the coil spring member 21 is centered in the radial direction d as shown in FIG. Configured to be located.

このため、前記保持ロープ部材２４は、コイル部２１ａの内周面から上，下方向で略均等に離間しているので、更に、隣接するコイル間に、保持ロープ２４ａが噛み込まれる虞を減少させることができる。   For this reason, the holding rope member 24 is spaced substantially evenly upward and downward from the inner peripheral surface of the coil portion 21a, further reducing the possibility of the holding rope 24a being caught between adjacent coils. Can be made.

更に、この実施の形態では、前記コイルスプリング部材２１には、前記コイル部２１ａと、このコイル部２１ａに連設されて、直線状を呈するロープ逃がし代部２１ｂとが設けられている。   Furthermore, in this embodiment, the coil spring member 21 is provided with the coil portion 21a and a rope relief allowance portion 21b that is connected to the coil portion 21a and has a linear shape.

このため、図１中二点鎖線及び図５に示すように、前記ロープ逃がし代部２１ｂに相当する部分の前記保持ロープ部材２４は、蛇行するように撓んでも、前記コイルスプリング部材２１のコイル部２１ａに噛み込まれる虞が無く、前記車体側支持軸１６及び開閉体側支持軸１７間の寸法短縮代をこの部分で稼ぐことが出来る。   Therefore, as shown in the two-dot chain line in FIG. 1 and FIG. 5, even if the holding rope member 24 corresponding to the rope escape allowance portion 21b bends to meander, the coil of the coil spring member 21 There is no risk of being caught in the portion 21a, and a dimensional reduction allowance between the vehicle body side support shaft 16 and the opening / closing body side support shaft 17 can be earned in this portion.

この実施の形態の保持ロープ部材２４の幅方向寸法Ｗ１は、図６に示すように、コイルスプリング部材２１のコイル部２１ａの内径寸法ｄ２に近接するように、この保持ロープ２４ａの幅方向各両側縁と、コイル部２１ａの内側面との間隔が、各々約１ｍｍ程度に収まるように設定されている。   As shown in FIG. 6, the width R1 of the holding rope member 24 in this embodiment is close to the inner diameter d2 of the coil portion 21a of the coil spring member 21. The distance between the edge and the inner side surface of the coil portion 21a is set to be about 1 mm.

このため、コイル部２１ａ内側面の上，下方向では、更に幅方向寸法が、内径寸法ｄ２
よりも小さくなるので、保持ロープ２４ａの上，下方向への移動が規制される。 For this reason, in the upper and lower directions of the inner surface of the coil portion 21a, the width direction dimension is further set to the inner diameter dimension d2.
Therefore, the movement of the holding rope 24a in the upward and downward directions is restricted.

このように、前記コイル部２１ａの内径寸法ｄ２に、前記保持ロープ２４ａの幅方向寸法Ｗ１が近接していると、図５に示すように、収縮状態で、コイル部２１ａ内側に存在する保持ロープ部材２４の蛇行は、前記ロープ逃がし代部２１ｂに相当する部分の蛇行に比して、更に、緩やかにすることができる。   Thus, when the width direction dimension W1 of the holding rope 24a is close to the inner diameter dimension d2 of the coil portion 21a, the holding rope existing inside the coil portion 21a in the contracted state as shown in FIG. The meandering of the member 24 can be made gentler than the meandering of the portion corresponding to the rope relief allowance 21b.

従って、更に、前記保持ロープ２４ａが、前記コイルスプリング部材２１のコイル部２１ａに噛み込まれる虞を減少させることができる。   Therefore, the possibility that the holding rope 24a is caught in the coil portion 21a of the coil spring member 21 can be further reduced.

そして、図８に示すように、この実施の形態の保持ロープ部材２４の保持ロープ２４ａ，２４ａ間を接合する貼合固定部２５が、糸２７…による縫合で構成されている。   And as shown in FIG. 8, the bonding fixing | fixed part 25 which joins between the holding ropes 24a and 24a of the holding rope member 24 of this embodiment is comprised by the stitching | suture by the thread | sled 27 ....

また、この実施の形態の保持ロープ部材２４では、両端に位置する折り返し部である前記開閉体側折り返しループ部１２４ｃ及び車体側折り返しループ部１２４ｄが、糸２６，２６による略同様の縫合で構成されている。   Further, in the holding rope member 24 of this embodiment, the opening / closing body side folding loop portion 124c and the vehicle body side folding loop portion 124d, which are folding portions located at both ends, are configured by substantially the same stitching with the threads 26, 26. Yes.

このため、固定や接続の為に、別途部品を追加する必要が無いので、製造コストの増大を抑制できると共に、別途部品が必要無い分、部品配置スペースを設ける必要が無くなり、レイアウトが容易に行えて、設計自由度を増大させることができる。   For this reason, there is no need to add additional parts for fixing and connection, so that it is possible to suppress an increase in manufacturing cost, and it is not necessary to provide additional parts placement space, and layout can be easily performed. Thus, the degree of freedom in design can be increased.

更に、また、この実施の形態の保持ロープ部材２４では、両端に位置する折り返し部である前記開閉体側折り返しループ部２４ｃ及び車体側折り返しループ部２４ｄが、各保持ロープ部材２４ａ，２４ａの端部２４ｂ，２４ｂを重合させて構成されているので、折り返し部分の強度を向上させることができる。   Furthermore, in the holding rope member 24 of this embodiment, the opening / closing body side folding loop portion 24c and the vehicle body side folding loop portion 24d, which are the folding portions located at both ends, are connected to the end portions 24b of the holding rope members 24a and 24a. , 24b are polymerized, so that the strength of the folded portion can be improved.

しかも、端部２４ｂ，２４ｂを重合させた部分を、糸２６…によって、面内，外方向に縫合しているので、前記保持ロープ部材２４の張設方向へ加わる力が、端部２４ｂ，２４ｂ間に面延設方向へスラストする力として作用しても、有効に受け止めることが出来、接着材等による接合よりも強固な接続を得られる。   In addition, since the portions where the end portions 24b and 24b are overlapped are stitched in the in-plane and outward directions by the threads 26, the force applied in the extending direction of the holding rope member 24 is applied to the end portions 24b and 24b. Even if it acts as a force thrusting in the surface extending direction in between, it can be effectively received, and a stronger connection can be obtained than the joining by an adhesive or the like.

図９は、この発明の実施の形態の実施例１の保持ロープ部材１２４を示すものである。   FIG. 9 shows the holding rope member 124 of Example 1 of the embodiment of the present invention.
