Description

【０００１】
【発明の属する技術分野】
この発明は、荷物の保管、運搬の際に使用するフォークリフト用の合成樹脂製パレットに係り、特に支柱部の隅部が耐衝撃性に優れている合成樹脂製パレットに関する。
【０００２】
【従来の技術】
従来、荷物の保管、運搬に使用されるフォークリフト用パレットでは、耐腐食性、耐汚染性に優れている合成樹脂製パレットが広く使用されている。図２は、四方差しパレットの一例を示す。四方差しパレット１は、上部デッキボード３と下部デッキボード５とを四隅の支柱部７、その中間に設けた中間支柱部９及び四隅を結ぶ対角線上の交差部に設けた中央支柱部で連結し、前記上下デッキボードと支柱部７、９で囲まれた空隙をフォーク差込口１１としている。
【０００３】
上記パレット１は、予め各支柱部の略中央部における水平方向の分割面１３で分割成形した上部デッキボードを有する上部品１Ａと、下部デッキボードを有する下部品１Ｂとを分割面１３において突き合わせ溶着してなる。四隅支柱部７を形成する上部デッキボード側分割部７Ａと下部デッキボード側分割部７Ｂ、及び中間支柱部９を形成する上部デッキボード側分割部９Ａと下部デッキボード側分割部９Ｂは、ともに閉じた中空構造を構成している。前記上部デッキボード３と下部デッキボード５の表面は、それぞれ平滑面に形成され、その内側面には補強リブが設けられている。
【０００４】
上記構成のフォーク差込口におけるデッキボード及び支柱部は、荷物を載置したときに高荷重を受けるばかりでなく、フォークリフトによる荷役作業中にフォークの接触及び衝撃を受けることになる。また、斜め方向に落下するときなどに、四隅支柱部７の先端角部が地面等に衝突することがある。合成樹脂製パレットは、木製パレットに比較して耐衝撃性が悪く破損し易いという問題がある。
【０００５】
そこで、合成樹脂製パレットにおいては高い衝撃強度を持たせるためのリブ構造が提案されている。例えば、支柱部を補強したパレットとして、特開平９−１７５５３４号公報、特開平４−２４２５４０号公報などに記載されたパレットがある。
【０００６】
【発明が解決しようとする課題】
前記公報記載のパレットは、中空構造とした支柱部の内部に角部位置から対角線上に中央部に向かう仕切壁を設け、さらに、フォークの差込方向に沿って前記仕切壁と交差する仕切壁とを設けたものである。このような構造では、四隅支柱部７の先端角部が衝撃を受けた場合には、必ずしも十分な強度を有するものではなかった。
【０００７】
落下時の四隅支柱部７の先端角部での耐衝撃性を高めるには、デッキボードのリブ構造と支柱部の構造とは互いに関係しており、両者の関係が重要であることが分かった。そこで、この発明の目的は、四隅支柱部の耐衝撃性を高める合成樹脂製パレットを提供するものである。
【０００８】
【課題を解決するための手段】
この発明は上記目的を達成するために次のような構成とした。即ち、この発明の合成樹脂製パレットは、上部デッキボードと下部デッキボードとを中空構造の支柱部で連結し、前記支柱部と上部デッキボード及び下部デッキボードで囲まれた空隙をフォーク差込口とした合成樹脂製パレットにおいて、四隅支柱部内にパレットの隣り合う側面に対して直交し、支柱部と同じ高さの仕切リブが連結することによって、支柱部の側壁とともに密閉した第１中空部を形成し、四隅支柱部内に開口縁部の接線に対してほぼ直交する方向に設けた支柱部と同じ高さの仕切リブと前記第１中空部を形成する仕切リブとをパレットの側面に対して平行に設けた支柱部と同じ高さの仕切リブが連結することによって第２中空部を形成し、前記第１中空部内に支柱部の角部から対角線上に補強リブを設け、前記対角線上の補強リブにパレットの側面に対して直交する補強リブを連結させたことを特徴とする。
【０００９】
第１中空部を形成する支柱部と同じ高さの仕切リブは支柱部の略中央部で連結している。また、第１中空部内の略対角線上の補強リブと、前記対角線上の補強リブに連結しパレットの側面に対して直交する補強リブの高さは、第１中空部を形成する仕切リブよりも低く形成することができる。また、第１中空部を形成する仕切リブと対角線上の補強リブに連結しパレットの側面に対して直交する補強リブは、ほぼ平行に設けることが好ましい。
【００１０】
【発明の実施の形態】
図１は、四隅支柱部７を分割面１３で分割した下部デッキボード側分割部７Ｂの要部断面図である。四隅支柱部７、７のフォーク差込口１１に面する側壁のうち、開口縁部７ａは、フォークの差し込みを容易にするために開口に向かって広がっており、平面において傾斜面又は湾曲面に形成されている。また、四隅の支柱部７には、前記傾斜面又は湾曲面とされた開口縁部７ａの接線に対してほぼ直交する方向に仕切リブ７ｂが設けられ、パレットの側面に対して直交する仕切リブ７ｃが設けられている。
【００１１】
さらに、四隅の支柱部７において、開口縁部７ａに設けられた仕切リブ７ｂ、７ｂは、ほぼ同一線上において対向するように設けられており、対角線を挟んでほぼ対称をなしている。前記仕切リブ７ｃ、７ｃは、四隅支柱部のほぼ中央部において連結している。前記仕切リブ７ｂと仕切リブ７ｃは、パレットの側面に対して平行な仕切リブ７ｄによって連結されている。
【００１２】
前記仕切リブ７ｂ、７ｃ及び７ｄは、支柱部と同じ高さに形成され、分割面において溶着される。従って、支柱部７の内部には、仕切リブ７ｃ、７ｃによって密閉した第１中空部２０と、仕切リブ７ｂ、７ｃ及び７ｄによって密閉した第２中空部２１とが形成されることになる。また、前記仕切リブ７ｃの延長線上には、補強リブ１５、１５が設けられている。
【００１３】
さらに、四隅支柱部７のパレット中央部側の隅部には、パレットの側面に対して平行な補強リブ１６、１６が設けられており、支柱部７の側壁とともに平面方形状を形成している。前記補強リブ１５、１６は、支柱部の側壁から一定の範囲のみが支柱部の高さと同じ高さに形成されており、分割面において溶着される。
【００１４】
四隅支柱部７の対角線上の外側隅部には、補強リブ１７、１８が設けられている。前記補強リブ１７は、支柱部の角部と仕切リブ７ｃ、７ｃの連結部１９とを連結しており、補強リブ１８は、補強リブ７ｃと同様に、パレットの側面に対して直交して設けられており、補強リブ１７のほぼ中間部に連結している。前記補強リブ１７、１８は、補強リブ１５、１６と同じ高さに形成すればよい。
【００１５】
上記の通り、四隅支柱部７の外側隅部には、略対角線上の補強リブ１７と、前記補強リブ１７に連結しパレットの側面に対して直交する補強リブ１８を設けたから、図２に示すように、落下等によって下面デッキボードの表面に対して斜め方向から衝撃を受けた場合にも変形や破損のおそれがない。また、補強リブ１７を補強リブ７ｃ、７ｃの連結部１９と連結することにより、耐衝撃性を一層増大させることができる。
【００１６】
尚、上記実施形態では、下部デッキボード５の四隅支柱部について説明したが、上部デッキボード３においても同様に形成することができるのは勿論である。重複を避けるために、上部デッキボードについての説明は省略する。また、上記実施形態では四方差しパレットについて説明したが、二方差しパレットでもよいのは勿論、両面使用パレット、片面使用パレットのいずれにも適用することができる。
【００１７】
【発明の効果】
この発明に係る合成樹脂製パレットは、四隅支柱部内にパレットの側面に対して直交する仕切リブを設けて四隅支柱部の外側隅部に密閉した第１中空部を形成し、四隅支柱部内に開口縁部の接線に対してほぼ直交する方向に設けた支柱部と同じ高さの仕切リブと前記第１中空部を形成する仕切リブとをパレットの側面に対して平行に設けた支柱部と同じ高さの仕切リブが連結することによって第２中空部を形成し、前記第１中空部内に略対角線上の補強リブと、前記対角線上の補強リブに連結する補強リブを設けたから、パレットの表面に対する斜め方向からの衝撃に対して優れた耐衝撃性を有することとなり、落下による衝突に対しても容易に変形したり破損したりすることがない。また、デッキボードや支柱部の肉厚を厚くすることなく耐衝撃強度を高めることができるから、パレット自体の重量を増大することなく、成型上も有利である。

BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin pallet for forklifts used for storing and transporting luggage, and more particularly to a synthetic resin pallet in which corners of struts are excellent in impact resistance.
[0002]
[Prior art]
Conventionally, forklift pallets used for storage and transportation of luggage, synthetic resin pallets having excellent corrosion resistance and contamination resistance have been widely used. FIG. 2 shows an example of a four-way pallet. The four-way pallet 1 connects the upper deck board 3 and the lower deck board 5 with four corner support sections 7, an intermediate support section 9 provided in the middle, and a central support section provided at a diagonal intersection connecting the four corners. The fork insertion port 11 is a space surrounded by the upper and lower deck boards and the column portions 7 and 9.
[0003]
In the pallet 1, the upper part 1A having an upper deck board and the lower part 1B having a lower deck board, which have been divided and formed by a horizontal dividing surface 13 at a substantially central portion of each support column in advance, are butt-welded on the dividing surface 13. Do it. The upper deck board side divided portion 7A and the lower deck board side divided portion 7B that form the four corner column portions 7 and the upper deck board side divided portion 9A and the lower deck board side divided portion 9B that form the intermediate column portion 9 are both closed. Constitutes a hollow structure. The surfaces of the upper deck board 3 and the lower deck board 5 are formed as smooth surfaces, and reinforcing ribs are provided on the inner side surfaces thereof.
[0004]
The deck board and the strut portion in the fork insertion port having the above-described structure not only receive a high load when a load is placed, but also receive a fork contact and an impact during a cargo handling operation by a forklift. In addition, the tip corners of the four corner struts 7 may collide with the ground or the like when falling in an oblique direction. Synthetic resin pallets have a problem that they have poor impact resistance and are easily damaged compared to wooden pallets.
[0005]
Therefore, a rib structure for providing high impact strength has been proposed for synthetic resin pallets. For example, there are pallets described in JP-A-9-175534, JP-A-4-242540, and the like as pallets with reinforced support portions.
[0006]
[Problems to be solved by the invention]
The pallet described in the above publication is provided with a partition wall that goes diagonally from the corner position to the center portion inside the column portion that has a hollow structure, and further intersects with the partition wall along the fork insertion direction. Are provided. In such a structure, when the tip corner portion of the four-corner column portion 7 receives an impact, it does not necessarily have sufficient strength.
[0007]
It was found that the rib structure of the deck board and the structure of the column part are related to each other and the relationship between them is important in order to improve the impact resistance at the tip corner part of the four corner column part 7 when dropped. . Accordingly, an object of the present invention is to provide a synthetic resin pallet that improves the impact resistance of the four corner struts.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is configured as follows. That is, the synthetic resin pallet according to the present invention connects the upper deck board and the lower deck board with a support column having a hollow structure, and a fork insertion port is formed between the support column, the upper deck board and the lower deck board. In the synthetic resin pallet, the first hollow portion sealed together with the side wall of the support column is formed by connecting partition ribs orthogonal to the adjacent side surfaces of the pallet in the four corner support units and having the same height as the support column. The partition rib having the same height as the support column provided in the direction substantially orthogonal to the tangent of the opening edge in the four corner support column and the partition rib forming the first hollow portion are formed on the side surface of the pallet. A second hollow portion is formed by connecting partition ribs having the same height as the pillar portions provided in parallel, reinforcing ribs are provided diagonally from the corner portions of the pillar portions in the first hollow portion, and on the diagonal lines. Supplement Characterized in that by connecting the reinforcing rib perpendicular to the sides of the pallet to the rib.
[0009]
The partition ribs having the same height as the support pillars forming the first hollow part are connected at the substantially central part of the support pillars. The height of the reinforcing rib on the substantially diagonal line in the first hollow portion and the reinforcing rib connected to the diagonal reinforcing rib and orthogonal to the side surface of the pallet is higher than that of the partition rib forming the first hollow portion. It can be formed low. In addition, it is preferable that the partition rib forming the first hollow portion and the reinforcement rib connected to the diagonal reinforcement rib and orthogonal to the side surface of the pallet are provided substantially in parallel.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a cross-sectional view of a main part of a lower deck board side dividing portion 7B in which the four corner support portions 7 are divided by a dividing surface 13. Of the side walls facing the fork insertion port 11 of the four corner struts 7, 7, the opening edge 7 a is widened toward the opening to facilitate the insertion of the fork, and is inclined or curved in the plane. Is formed. Further, the four pillars 7 are provided with partition ribs 7b in a direction substantially perpendicular to the tangent to the opening edge 7a which is the inclined surface or curved surface, and the partition ribs perpendicular to the side surface of the pallet. 7c is provided.
[0011]
Further, in the four corner support portions 7, the partition ribs 7b and 7b provided on the opening edge portion 7a are provided so as to face each other on substantially the same line, and are substantially symmetric with respect to the diagonal line. The partition ribs 7c and 7c are connected at substantially the center of the four corner struts. The partition rib 7b and the partition rib 7c are connected by a partition rib 7d parallel to the side surface of the pallet.
[0012]
The partition ribs 7b, 7c, and 7d are formed at the same height as the support column, and are welded on the divided surfaces. Accordingly, the first hollow portion 20 sealed by the partition ribs 7c and 7c and the second hollow portion 21 sealed by the partition ribs 7b, 7c and 7d are formed inside the support column portion 7. Reinforcing ribs 15 are provided on the extension line of the partition rib 7c.
[0013]
Furthermore, reinforcing ribs 16 and 16 parallel to the side surface of the pallet are provided at corners on the pallet central portion side of the four corner support portions 7, and form a planar rectangular shape together with the side walls of the support portions 7. . The reinforcing ribs 15 and 16 are formed to have the same height as that of the support portion only in a certain range from the side wall of the support portion, and are welded on the divided surfaces.
[0014]
Reinforcing ribs 17 and 18 are provided at the outer corners on the diagonal lines of the four corner struts 7. The reinforcing rib 17 connects the corner portion of the support column and the connecting portion 19 of the partition ribs 7c and 7c, and the reinforcing rib 18 is provided orthogonal to the side surface of the pallet similarly to the reinforcing rib 7c. It is connected to the substantially middle part of the reinforcing rib 17. The reinforcing ribs 17 and 18 may be formed at the same height as the reinforcing ribs 15 and 16.
[0015]
As described above, the outer corners of the four corner struts 7 are provided with reinforcing ribs 17 on substantially diagonal lines and reinforcing ribs 18 connected to the reinforcing ribs 17 and orthogonal to the side surfaces of the pallet, as shown in FIG. Thus, there is no risk of deformation or breakage even when an impact is applied to the surface of the lower deck board from an oblique direction due to dropping or the like. Further, by connecting the reinforcing rib 17 to the connecting portion 19 of the reinforcing ribs 7c and 7c, the impact resistance can be further increased.
[0016]
In the above embodiment, the four corner support portions of the lower deck board 5 have been described, but it is needless to say that the upper deck board 3 can be similarly formed. In order to avoid duplication, description of the upper deck board is omitted. Moreover, although the four-way pallet has been described in the above embodiment, it can be applied to both a double-sided pallet and a single-sided pallet as well as a two-way pallet.
[0017]
【The invention's effect】
The synthetic resin pallet according to the present invention is provided with partition ribs orthogonal to the side surface of the pallet in the four corner struts to form a first hollow portion sealed at the outer corner of the four corner struts, and opened in the four corner struts. The same as the column part provided with the partition rib having the same height as the column part provided in the direction substantially orthogonal to the tangent to the edge part and the partition rib forming the first hollow part in parallel to the side surface of the pallet. Since the second hollow portion is formed by connecting the partition ribs having a height , a reinforcing rib substantially diagonally and a reinforcing rib connected to the diagonally reinforcing rib are provided in the first hollow portion. Therefore, it has excellent impact resistance against an impact from an oblique direction, and is not easily deformed or damaged even by a collision caused by dropping. In addition, since the impact strength can be increased without increasing the thickness of the deck board or the column, the molding is advantageous without increasing the weight of the pallet itself.
