Description
本発明は車両用エアコンダクト等に使用される一体に形成された取付部を有する中空成形体に関するものである。 The present invention relates to a hollow molded body having an integrally formed mounting portion used for a vehicle air conditioner duct or the like.
自動車内を快適な環境にしたり、フロントガラスの曇りを防止するために、自動車にはエアコンなどの空調設備が設けられている。この空調設備から出される調温空気はエアコンユニットからダクトを通って車両室内に送られる。このような自動車用のダクトは、従来からブロー成形による中空成形体が広く用いられている。
従来技術としては、軟化状態にある発泡樹脂パリソンを、開閉可能な分割型金型内に配置し、該発泡樹脂パリソンを金型で挟み込み発泡樹脂パリソン内に気体を吹き込んで発泡樹脂中空成形体を製造する方法において、分割型金型の閉合に伴って発泡樹脂パリソンの少なくとも一部を、成形される発泡樹脂中空成形体の外壁面より外側に突出させ、該突出部を重ね合わせて押し潰すことにより、密度が０．５ｇ／ｃｍ３以上であり、且つ坪量が該発泡樹脂中空成形体の本体部の坪量の２倍を超える平坦部を有する取付け部材を有する発泡樹脂中空成形体の製造方法及び中空成形体（例えば、特許文献１参照）が存在している。
In order to make the interior of the automobile a comfortable environment and to prevent the windshield from being fogged, the automobile is provided with air conditioning equipment such as an air conditioner. Temperature-controlled air emitted from the air conditioning equipment is sent from the air conditioner unit through the duct into the vehicle compartment. Conventionally, blow molded hollow molded bodies have been widely used for such automobile ducts.
As a conventional technique, a foamed resin hollow molded body is obtained by placing a foamed resin parison in a softened state in a split mold that can be opened and closed, sandwiching the foamed resin parison with a mold, and blowing a gas into the foamed resin parison. In the manufacturing method, when the split mold is closed, at least a part of the foamed resin parison is projected outward from the outer wall surface of the molded foamed resin hollow molded body, and the projected parts are overlapped and crushed. Manufacture of a foamed resin hollow molded body having a mounting member having a flat portion whose density is 0.5 g / cm 3 or more and whose basis weight exceeds twice the basis weight of the main body of the foamed resin hollow molded body There exists a method and a hollow molded body (see, for example, Patent Document 1).
前記従来技術は、軟化状態にある樹脂パリソンを、金型内に配置し、このパリソンを金型で挟み込み、パリソン内に気体を吹き込んで中空ダクトを製造するが、金型の閉合に伴いパリソンの一部を中空ダクトの外壁面より外側に突出させ、押し潰して取付部を形成するものである。
しかしながら前記従来技術は、この潰しによって形成された取付部が平板状であるため、中空ダクトの固定のために所定面積の取付部を設ける必要があり、取り付けられる位置の制限を受けやすいという問題がある。
また、平板状の取付部を湾曲形状である金属パイプにガタツキなく取り付けることが難しいという問題もある。
本発明は、これらの問題を解決したものであり、空調ダクトの取付部の剛性を向上させ、取付部を固定する被取付部が、例え湾曲形状であっても、ガタツキなく取り付けられるようにした一体に形成された取付部を有する中空成形体を提供するものである。
In the prior art, a resin parison in a softened state is placed in a mold, and the parison is sandwiched between molds, and a gas is blown into the parison to produce a hollow duct. A part protrudes outside the outer wall surface of the hollow duct and is crushed to form an attachment portion.
However, since the mounting portion formed by this crushing has a flat plate shape, it is necessary to provide a mounting portion having a predetermined area for fixing the hollow duct, and there is a problem that the mounting position is easily limited. is there.
Moreover, there is also a problem that it is difficult to attach the flat attachment portion to the curved metal pipe without rattling.
The present invention solves these problems, and improves the rigidity of the mounting portion of the air conditioning duct so that the mounted portion for fixing the mounting portion can be mounted without rattling even if the mounted portion has a curved shape. A hollow molded body having an integrally formed attachment portion is provided.
上記の目的を達成することができる本発明の第１発明は、請求項１に記載された通りの中空成形体であり、次のようなものである。
中空本体と、該中空本体の側面から外側へ延設する取付部とからなる中空成形体であって、前記取付部は係止手段で被取付部材と係止するための取付座と、前記取付部の延設方向に配置される第１の中空部と、該第１の中空部と交差する方向に配置される第２の中空部とを連通して設ける構成である。
The first invention of the present invention capable of achieving the above object is a hollow molded body as described in
A hollow molded body comprising a hollow main body and a mounting portion extending outward from a side surface of the hollow main body, wherein the mounting portion is a mounting seat for locking with a member to be mounted by a locking means, and the mounting The first hollow portion disposed in the extending direction of the portion and the second hollow portion disposed in the direction intersecting with the first hollow portion are provided in communication with each other .
上記の目的を達成することができる本発明の第２発明は、請求項２に記載された通りの中空成形体であり、次のようなものである。
請求項１に記載の発明に加えて、前記第２の中空部は、前記取付座を中間に位置して２本設ける構成である。
A second invention of the present invention capable of achieving the above object is a hollow molded body as described in
In addition to the first aspect of the present invention, the second hollow portion has a configuration in which two mounting seats are provided in the middle.
本発明に係る一体に形成された取付部を有する中空成形体は、上記説明のような構成を有するので、以下に記載する効果を奏する。
（１）中空本体の側面から外側へ一体に形成される取付部の延設方向に中空部を設けているので、取付部としての剛性が向上し、金属ブラケット等の補強部材を用いる必要がなく、取付部の面積を小さくすることができる。そのため、中空成形体を被取付部材に取り付ける場合に、周辺に配置される他部材との空間的な制約がなくなる。
（２）取付部の中空部は、延設方向の第１の中空部とこの第１の中空部と交差する第２の中空部とからなるので、取付部全体のねじれや撓みに対する剛性が向上し、さらに強固な取付部とすることができる。
（３）請求項２に記載の発明によると、２つの第２の中空部が延設方向で取付座を挟むように設けているので、被取付部材が湾曲形状であったとしても、ガタツクことなく固定することができる。
（４）取付部の取付座に係止手段を用いて被取付部材と係止固定したときに、第２の中空部が被取付部材と当接すると、被取付部材の形状に合わせて弾性変形するので、取付け後の取付部の安定性が向上する。
（５）本発明の一体に形成された取付部を有する中空成形体は金型織込みのため、製造が容易でコストの低下を図ることができる。
Since the hollow molded body having the integrally formed attachment portion according to the present invention has the configuration as described above, the following effects are achieved.
(1) Since the hollow portion is provided in the extending direction of the mounting portion that is integrally formed from the side surface of the hollow main body to the outside, the rigidity as the mounting portion is improved and there is no need to use a reinforcing member such as a metal bracket. The area of the mounting portion can be reduced. Therefore, when attaching a hollow molded object to a to-be-attached member, a spatial restriction | limiting with the other member arrange | positioned at the periphery is lose | eliminated.
(2) the hollow portion of the mounting portion taken, since and a second hollow portion which intersects the first hollow portion of the extending direction and the first hollow portion, the rigidity for the entire mounting section torsion or deflection It can improve and it can be set as a still stronger attachment part.
(3) According to the invention described in
(4) When the second hollow portion comes into contact with the mounted member when the mounting seat of the mounting portion is locked to the mounted member using the locking means, the elastic deformation is performed according to the shape of the mounted member. Therefore, the stability of the mounting portion after mounting is improved.
(5) Since the hollow molded body having the integrally formed attachment portion of the present invention is woven into a mold, it can be easily manufactured and the cost can be reduced.
中空本体と、該中空本体の側面から外側へ延設する取付部とからなる中空成形体であって、前記取付部はネジ、ボルト、クリップ等の係止手段で被取付部材と係止するための取付座と、延設方向に配置される第１の中空部と該第１の中空部と交差する方向に配置される第２の中空部を前記取付座を中間に位置して２本設ける一体に形成された取付部を有する中空成形体である。 A hollow molded body comprising a hollow main body and a mounting portion extending outward from a side surface of the hollow main body, the mounting portion being locked with a member to be mounted by a locking means such as a screw, a bolt, or a clip. Two mounting seats, a first hollow portion arranged in the extending direction, and a second hollow portion arranged in a direction intersecting the first hollow portion are provided with the mounting seat in the middle. This is a hollow molded body having an integrally formed mounting portion.
