〔考案の技術分野〕
本考案は、自動車などの車輌用パツケージトレ
イに関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a package tray for vehicles such as automobiles.
従来、車輌用パツケージトレイは、合成樹脂の
射出成形や真空成形などによつて１枚板状に形成
している。しかし、全体が１枚板状であるので、
その剛性が弱い。
Conventionally, vehicle package trays have been formed into a single plate by injection molding or vacuum forming of synthetic resin. However, since the whole is a single plate,
Its rigidity is weak.
また、車輌用パツケージトレイの前縁部は乗員
のひざのあたりに位置するので、車輌が事故など
を起した場合、乗員のひざが前縁部に当つてけが
をする危険性があり、そのため前縁部を折り返す
ような構造を採用したものもあるが、その折り返
し部の下端が板状になつているものでは、下から
の突き上げなどの場合には危険性が残つている。 In addition, the front edge of the vehicle package tray is located near the passenger's knees, so if the vehicle is involved in an accident, there is a risk that the passenger's knees will hit the front edge and cause injury. Some devices have a structure in which the edges are folded back, but the lower end of the folded section is plate-shaped, so there is still a risk of being pushed up from below.
そこで、たとえば、パツケージトレイ全体をブ
ロー成形によつて中空状に形成し、前縁部を中空
袋状に形成することにより、安全性を向上するこ
とが考えられる。しかし、単にブロー成形により
形成しても、底部は２重構造となるだけで、ひね
り強度などが十分でない。 Therefore, it is conceivable to improve safety by, for example, forming the entire package tray into a hollow shape by blow molding, and forming the front edge into a hollow bag shape. However, even if it is simply formed by blow molding, the bottom part will only have a double structure, and the twisting strength etc. will not be sufficient.
そこで、さらに発展させると、第１図に示すよ
うに、パツケージトレイ全体をブロー成形によつ
て中空状に形成し、前縁部１を中空袋状に形成す
るとともに、底部の外側底板２にビード状部３を
形成して内側底板４と接合し、強度を向上するこ
とが考えられる。 Therefore, to further develop the package tray, as shown in Fig. 1, the entire package tray is formed into a hollow shape by blow molding, the front edge 1 is formed into a hollow bag shape, and a bead is formed on the outer bottom plate 2 at the bottom. It is conceivable that the shaped portion 3 is formed and joined to the inner bottom plate 4 to improve the strength.
しかし、このようなものでは、その成形のエア
吹込み時に、第２図に示すように、エアがビード
状部３の壁に当つて反対側部分のエア圧力が低
く、成形不良が起きる場合があり、また、ビード
状部３の接合する内側底板４の上面に艶むらが発
生したり、ヒケなどによつて成形変形が発生した
りする問題がある。 However, in such a product, when air is blown for molding, as shown in Figure 2, the air hits the wall of the bead-shaped portion 3 and the air pressure on the opposite side is low, resulting in molding defects. Furthermore, there are problems in that uneven gloss occurs on the upper surface of the inner bottom plate 4 to which the bead-shaped portion 3 is joined, and molding deformation occurs due to sink marks and the like.
本考案は、このような問題を解決しようとする
もので、安全性を向上するとともに、強度的にも
十分なものを提供することを目的とするものであ
る。
The present invention is an attempt to solve such problems, and aims to improve safety and provide sufficient strength.

The outer bottom plate is formed into a hollow shape by the outer bottom plate, a protrusion is formed on the outer bottom plate toward the inner bottom plate, and a protrusion is formed on the protrusion that is joined to the inner bottom plate. A gap corresponding to the height of the protrusion is formed between the bottom plate and the protrusion of the outer bottom plate.
以下、本考案の一実施例を第３図ないし第６図
を参照して説明する。
Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 3 to 6.
１１は合成樹脂ブロー成形によつて一体に形成

ン状の突起１６が設けられている。 11 is a package tray body integrally formed by synthetic resin blow molding;
The outer peripheral edge portion 12 is formed into a hollow bag shape.
Further, the bottom of the main body 11 is formed into a hollow shape by an inner bottom plate 13 and an outer bottom plate 14, and this outer bottom plate 1
4 are provided with elongated bead-shaped protrusions 15 facing toward the inner bottom plate 13 and at predetermined intervals in the length direction of the main body 11.
A pin-shaped protrusion 16 for joining the inner bottom plate 13 is provided at an appropriate position on the upper surface of the holder.
そして、ブロー成形時には、一方から吹込まれ

体に行きわたり、成形が良好に行われる。 During blow molding, air blown from one side is applied to the protrusions 15 of the inner bottom plate 13 and the outer bottom plate 14.
It spreads over the entire area through a gap 17 corresponding to the height of the protrusion 16 between the two, and molding is performed satisfactorily.
１８は取付片である。 18 is a mounting piece.

It may be in line contact with 3.
また、外周縁部１２の中空部は、少なくとも前
縁部に形成すればよい。 Further, the hollow portion of the outer peripheral edge portion 12 may be formed at least at the front edge portion.

According to the present invention, safety is improved by forming the main body by blow molding and forming the front edge into a bag shape, and by providing a protrusion at the bottom that connects the protrusion of the outer bottom plate to the inner bottom plate. The strength is also satisfactory, and since there is a gap equal to the height of the protrusions between the inner and outer bottom plate protrusions, there will be no molding defects due to lack of air during blow molding. By joining only at the protruding portions, molding can be performed satisfactorily without causing uneven gloss or sink marks on the surface of the inner bottom plate.
