図４に示した板材は、例えば一定の板厚（例えば３ｍｍ）の鋼板から形成されており、その上面には複数の滑り止め加工部４０が規則的（不規則でも良い）に配置されている。   The plate material shown in FIG. 4 is formed of, for example, a steel plate having a constant plate thickness (for example, 3 mm), and a plurality of anti-slip processed portions 40 are regularly (or irregularly) arranged on the upper surface thereof. .

図５は滑り止め加工部４０の単体の拡大平面図、図６は図５中のVI−VI断面による断面図、図７は図５中のVII−VII断面による断面図、図８は滑り止め加工部４０を構成する凸部４１（後述）の斜視図である。   5 is an enlarged plan view of a single part of the anti-slip processing portion 40, FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. 5, FIG. 7 is a cross-sectional view taken along the line VII-VII in FIG. It is a perspective view of the convex part 41 (after-mentioned) which comprises the process part 40. FIG.

図５−図８に示すように、滑り止め加工部４０は、４つの凸部４１を十文字状に配置して構成されており、４つの凸部４１を一組として滑り止め加工部の単体を構成している。凸部４１は、荷受台基端部２３の荷受面の基面４５に連続し互いに対向配置された１対の基部４２、これら基部４２の間にて基面４５から突出させ架橋させるようにして形成したブリッジ部４３、ブリッジ部４３の上面に形成された平坦な荷受面部４４を有している。   As shown in FIG. 5 to FIG. 8, the anti-slip processing unit 40 is configured by arranging four convex portions 41 in a cross shape, and a single anti-slip processing unit is formed with the four convex portions 41 as a set. It is composed. The convex portion 41 is continuous with the base surface 45 of the load receiving surface of the load receiving base end portion 23, and is configured to project from the base surface 45 and bridge between the pair of base portions 42 disposed opposite to each other. The bridge portion 43 is formed, and the flat load receiving surface portion 44 is formed on the upper surface of the bridge portion 43.

上記ブリッジ部４３は、切り起こし用の金型でパンチング加工し、両サイドを剪断してブリッジ状に突出させることで形成されている。ブリッジ部４３の基面４５からの高さｈは、基面を構成する板材の板厚ｔよりも低く、ブリッジ部４３と基面４５との間に間隙が生じないようになっている。   The bridge portion 43 is formed by punching with a die for cutting and raising, and shearing both sides to project in a bridge shape. The height h of the bridge portion 43 from the base surface 45 is lower than the plate thickness t of the plate material constituting the base surface, so that no gap is generated between the bridge portion 43 and the base surface 45.

凸部４１は単体で見ると、上方から見て概略矩形に形成され、矩形の１対の長辺部が基面４５を剪断して形成された剪断面４６、１対の短辺部が基部４２をなしている。基部４２はパンチング加工により剪断されない部分であり、基面から連続して立ち上がりブリッジ部４３を支持する部分である。ブリッジ部４３の剪断面４６と荷受面部４４との境界部分はエッジが立っている（角になっている）。ブリッジ部４３の基部４２と荷受面部４４との境界部分はエッジが立っていても（角になっていても）良いが、実際には丸みを帯びることが多い。荷受面部４４は荷受台５の荷受面とほぼ平行である。   When the convex portion 41 is viewed as a single unit, the convex portion 41 is formed in a substantially rectangular shape when viewed from above, and a pair of long sides of the rectangle is formed by shearing the base surface 45, and a pair of short sides is the base. 42. The base portion 42 is a portion that is not sheared by punching, and is a portion that rises continuously from the base surface and supports the bridge portion 43. The boundary portion between the shear surface 46 and the load receiving surface portion 44 of the bridge portion 43 has an edge (has a corner). The boundary portion between the base portion 42 and the cargo receiving surface portion 44 of the bridge portion 43 may have an edge (may be a corner), but is actually often rounded. The load receiving surface portion 44 is substantially parallel to the load receiving surface of the load receiving platform 5.

このような凸部４１を４つ十文字状に配置した滑り止め加工部４０において、剪断面４６は放射状に（前後方向及び左右方向に）伸び、前後方向・左右方向のいずれから見ても４つのうちの２つの凸部４１の剪断面４６が対向するようになっている。   In the anti-slip processing portion 40 in which the four convex portions 41 are arranged in a four-letter shape, the shear surface 46 extends radially (in the front-rear direction and the left-right direction), and there are four when viewed from both the front-rear direction and the left-right direction. The shearing surfaces 46 of the two convex portions 41 are opposed to each other.

次に、図９−図１５を用いて本実施の形態の滑り止め構造を適用した格納式荷受台昇降装置４の動作を説明する。図９−図１５では操作部３４を図示省略してある。   Next, the operation of the retractable load receiving table elevating device 4 to which the anti-slip structure of the present embodiment is applied will be described with reference to FIGS. 9 to 15, the operation unit 34 is not shown.

まず、荷受台５を図９に示す格納状態から図１３に示す作業状態に移行させる荷受台展開時の動作について説明する。図９のように荷受台５が格納姿勢にあるとき、操作部３４で所定の操作を行うと、動力装置３３からの電力を駆動源として図示しない油圧ポンプからの圧油がスライドシリンダ１４のボトム側に供給されてスライドシリンダ１４が伸長方向に駆動する。スライドシリンダ１４が伸長し、図１０のようにスライダ９が後端側ストッパ１６に当接したことが図示しない後端センサに検出されると、荷受台基端部２３が下降し、荷受台本体部２５及び荷受台先端部２７は支持ローラ１２に倣って荷受台基端部２３に対し回動する。そして、図１１に示したように荷受台基端部２３が接地し、荷受台本体部２５及び荷受台先端部２７が支持ローラ１２に立て掛けられるように起立した状態となる。 (1) Unloading operation of the load receiving table First, an operation at the time of unloading the load receiving table for shifting the receiving table 5 from the storage state shown in FIG. 9 to the working state shown in FIG. 13 will be described. As shown in FIG. 9, when a predetermined operation is performed with the operation unit 34 when the load receiving platform 5 is in the retracted position, the pressure oil from a hydraulic pump (not shown) is supplied from the power unit 33 to the bottom of the slide cylinder 14. The slide cylinder 14 is driven in the extending direction. When the slide cylinder 14 is extended and the rear end sensor (not shown) detects that the slider 9 is in contact with the rear end side stopper 16 as shown in FIG. The portion 25 and the load receiving table distal end portion 27 are rotated with respect to the load receiving table base end portion 23 along the support roller 12. Then, as shown in FIG. 11, the load receiving base end portion 23 is grounded, and the load receiving stand main body portion 25 and the load receiving stand distal end portion 27 stand up so as to lean against the support roller 12.

荷受台５が図１１のような姿勢になったら、操作者は折り畳まれた状態の荷受台５を展開する。この場合、まず荷受台本体部２５に設けた図示しないグリップを引き、荷受台本体部２５を略水平状態に展開する（図１２参照）。続いて、荷受台先端部２７に設けた図示しないグリップを引き、荷受台先端部２７を略水平状態に展開する（図１３参照）。   When the load receiving stand 5 is in the posture as shown in FIG. 11, the operator unfolds the load receiving stand 5 in a folded state. In this case, first, a grip (not shown) provided on the cargo cradle body 25 is pulled to unfold the cargo cradle body 25 in a substantially horizontal state (see FIG. 12). Subsequently, a grip (not shown) provided at the tip of the load receiving table 27 is pulled to expand the load receiving tip end portion 27 in a substantially horizontal state (see FIG. 13).

以上の操作によって、荷受台５が展開し、図５−図８の本実施の形態の滑り止め構造を施した荷受台基端部２３の荷受面が露出し、その上部に作業者や荷物を載せることができるようになる。荷受台５を格納する際は、上記手順と逆の手順を行う。   By the above operation, the load receiving platform 5 is unfolded, the load receiving surface of the load receiving platform base end portion 23 having the anti-slip structure of the present embodiment shown in FIGS. It can be put on. When storing the cargo receiving stand 5, the reverse procedure to the above procedure is performed.

（２）荷受台昇降（作業支援）動作
次に図１３−図１５を用いて格納式荷受台昇降装置４における荷受台５の作業時の昇降動作について説明する。荷受台５を展開した後、操作部３４で所定の操作を行うと、リフトシリンダ２２のボトム側に圧油が供給されてリフトシリンダ２２が伸長方向に駆動し、図１５に示すように荷受台５を車両の荷台３の床面高さまで上昇する。荷受台５を下降させるときには、操作部３４で所定の操作を行うと油圧ポンプ３７が停止してリフトシリンダ２２の保持圧が開放され、荷受台５やアーム１９−２１あるいは荷受台５上の作業者や荷物等の重みによって荷受台５が下降する。リフトシリンダ２２の縮退時にボトム側から押し退けられた戻り油は図示しない作動油タンクに戻される。 (2) Elevating / lowering operation (work support) operation Next, the elevating operation during the operation of the load receiving platform 5 in the retractable load receiving platform elevating device 4 will be described with reference to FIGS. When a predetermined operation is performed by the operation unit 34 after the load receiving platform 5 is deployed, the pressure oil is supplied to the bottom side of the lift cylinder 22 and the lift cylinder 22 is driven in the extending direction, as shown in FIG. 5 is raised to the height of the floor of the loading platform 3 of the vehicle. When the load receiving platform 5 is lowered, if a predetermined operation is performed by the operation unit 34, the hydraulic pump 37 stops and the holding pressure of the lift cylinder 22 is released, and the work on the load receiving platform 5, the arm 19-21 or the load receiving platform 5 is performed. The cargo receiving platform 5 is lowered due to the weight of the person or baggage. The return oil pushed away from the bottom side when the lift cylinder 22 is retracted is returned to a hydraulic oil tank (not shown).

なお、図１３に示すように荷受台基端部２３が接地した状態まで荷受台５を下降させ、この状態でさらに同じ操作を続けると、荷受台基端部２３が接地した状態でリフトシリンダ２２が縮退する結果、第１アーム（チルトアーム）１９が回動して平行リンクの平行四辺形の頂点位置が崩れる。するとほぼ水平の姿勢を保っていた荷受台５が後方に向かって下り傾斜の姿勢に移行（チルト）し、図１４に示すように荷受台先端部２７の先端側が地面に近接することにより、台車等を荷受台５上に積載し易くなる。   As shown in FIG. 13, when the load receiving base 5 is lowered to the state where the load receiving base end portion 23 is grounded and the same operation is continued in this state, the lift cylinder 22 is maintained while the load receiving base base end portion 23 is grounded. As a result, the first arm (tilt arm) 19 rotates and the parallelogram apex position of the parallel link collapses. Then, the load receiving platform 5 that has maintained a substantially horizontal posture shifts downward (tilt) toward the rear, and as shown in FIG. Etc. can be easily loaded on the receiving tray 5.

続いて本実施の形態の滑り止め構造により得られる作用効果を説明する。   Next, functions and effects obtained by the anti-slip structure of the present embodiment will be described.

本実施の形態によれば、滑り止め加工部４０を構成する凸部４１が剪断加工により形成されたブリッジ部４３を有し、ブリッジ部４３の側面である剪断面４６と上面である荷受面部４４との境界に実質直角のエッジが形成されているので、剪断面を持たない凸部を滑り止めとして形成する場合に比べて滑り止め効果を飛躍的に向上させることができる。また、本実施の形態の場合、上記構成の凸部４１を十文字状に並べて滑り止め加工部４０を構成するため、滑り止め加工部４０の単体で見ても、複数の方向（本例の場合前後方向及び左右方向）に前述したエッジ部分が向くので、滑り止め効果が一方向に指向されず各方向に対する滑り止め効果が得られる。本実施の形態の滑り止め構造は、このような構成により滑り止め効果が飛躍的に向上し、例えば降雨時や降雪時であっても凸部４１が露出した状態にあれば十分な滑り止め効果が期待できる。   According to the present embodiment, the convex portion 41 constituting the anti-slip processing portion 40 has the bridge portion 43 formed by shearing, and the shear surface 46 that is the side surface of the bridge portion 43 and the load receiving surface portion 44 that is the upper surface. Since a substantially right-angled edge is formed at the boundary, the anti-slip effect can be dramatically improved as compared with the case where a convex portion having no shearing surface is formed as an anti-slip. Further, in the case of the present embodiment, the convex portions 41 having the above-mentioned configuration are arranged in a cross shape to constitute the anti-slip processing unit 40. Therefore, even when viewed as a single anti-slip processing unit 40, a plurality of directions (in this example) Since the edge portion described above faces in the front-rear direction and the left-right direction), the anti-slip effect is not directed in one direction, and an anti-slip effect in each direction can be obtained. The anti-slip structure of the present embodiment greatly improves the anti-slip effect by such a configuration. For example, even when it is raining or snowing, the anti-slip effect is sufficient if the convex portion 41 is exposed. Can be expected.

また、例えば図１６のように、周囲１箇所のみを基部４２’とし、それ以外の部分を剪断し持ち上げて凸部４１’を形成した場合を比較例に挙げる。この場合、凸部４１の上面が基部４２’から遠ざかるにつれて単調に高くなると、凸部４１’上に載置された荷物は最も基部４２’から遠く高位置にあるエッジ部分４７’により線で受けられる。車両用荷受台昇降装置の荷受台には例えばダンボールが直接置かれることも多く、このように線もしくは点で荷重を支える構造では面圧が高くなり過ぎ、ダンボールに破れが生じたり跡が付いたりし易くなる。   Further, for example, as shown in FIG. 16, a case where only one peripheral portion is the base 42 'and the other portions are sheared and lifted to form the convex portion 41' will be described as a comparative example. In this case, when the upper surface of the convex portion 41 increases monotonously as it moves away from the base portion 42 ′, the load placed on the convex portion 41 ′ is received by a line by the edge portion 47 ′ that is farthest from the base portion 42 ′ and located at a high position. It is done. For example, corrugated cardboard is often placed directly on the consignment of the vehicle consignment elevating device, and in such a structure that supports the load with a line or a point, the surface pressure becomes too high, and the cardboard is torn or marked. It becomes easy to do.

それに対し、本実施の形態の滑り止め構造では、各凸部４１の上面が平坦な荷受面部４４になっているので、荷物を面（荷受面部４４）により低い面圧で受けることができ、荷物に傷跡が付き難い。また、ブリッジ部４３は両側の基部４２で支持されているので、図１６の比較例に比べてブリッジ部４３が高剛性で疲労強度にも優れている。   In contrast, in the anti-slip structure of the present embodiment, since the upper surface of each convex portion 41 is a flat load receiving surface portion 44, the load can be received by the surface (the load receiving surface portion 44) with a lower surface pressure. It is hard to get a scar. Further, since the bridge portion 43 is supported by the base portions 42 on both sides, the bridge portion 43 has higher rigidity and excellent fatigue strength than the comparative example of FIG.

また、ブリッジ部４３の基面４５からの高さｈが板厚ｔよりも低い範囲に抑えられているので、ブリッジ部４３の両サイドが剪断面４６を形成してもブリッジ部４３と基面４５との間に生じる隙間を最小限に抑制することができ、荷受台５の内部への異物の侵入を抑制することができる。また、図１−図３に示したように車体の下部に荷受台が収容される格納式荷受台昇降装置に本実施の形態の滑り止め構造を適用した場合、走行中に車輪で跳ね上げられる泥や水が荷受台にかかることがある。これに対しても、ブリッジ部４３の周囲に間隙が生じないので荷受面の下方から跳ね上げられる水や泥が通過することがほとんどなく、荷受面が泥や水で濡れることを防止することができ、滑り止め効果を相乗的に発揮させることができる。   Further, since the height h from the base surface 45 of the bridge portion 43 is suppressed to a range lower than the plate thickness t, the bridge portion 43 and the base surface are formed even if both sides of the bridge portion 43 form the shear surface 46. 45 can be suppressed to a minimum, and entry of foreign matter into the interior of the load receiving tray 5 can be suppressed. In addition, when the anti-slip structure of the present embodiment is applied to the retractable load receiving device lifting device in which the load receiving device is accommodated in the lower part of the vehicle body as shown in FIGS. Mud and water may get on the cradle. Against this, since there is no gap around the bridge portion 43, water or mud splashed from below the cargo receiving surface hardly passes, and the cargo receiving surface can be prevented from getting wet with mud or water. The anti-slip effect can be exhibited synergistically.

（第２の実施の形態）
図１７は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第２の実施の形態を構成する滑り止め加工部の単体の拡大平面図、図１８は図１７中のXVIII−XVIII断面による断面図である。 (Second Embodiment)
FIG. 17 is an enlarged plan view of a single non-slip processing portion constituting the second embodiment of the anti-slip structure of the load cradle of the vehicle cradle lifting / lowering device of the present invention, and FIG. 18 is an XVIII-XVIII in FIG. It is sectional drawing by a cross section.

図１７及び図１８に示すように、本実施の形態の滑り止め加工部４０Ａの単体は、凸部４１Ａａ，４１Ａｂが第１の実施の形態と同じように上方から見て概略矩形に形成されているが、凸部４１Ａａ，４１Ａｂの短辺方向の長さＷａ，Ｗｂが異なっている。また、凸部４１Ａａ，４１Ａｂの配置も第１の実施の形態と相違しており、本実施の形態では、十文字状に配置した４つの凸部４１Ａａ，４１Ａｂが、それらの配置の中心点Ｏに対してそれぞれ所定距離Ｄａ−Ｄｄだけオフセットさせた位置関係に配置されている。オフセット距離Ｄａ−Ｄｄはそれぞれ又は組合せで相違していても良いし統一されていても良い。それ以外の構成は第１の実施の形態と同様であり、滑り止め加工部４０Ａを構成する各部のうち第１の実施の形態に対応する部分には符号に添え字「Ａ」を付して説明を省略する。   As shown in FIGS. 17 and 18, the single piece of the anti-slip processing portion 40A of the present embodiment has convex portions 41Aa and 41Ab formed in a substantially rectangular shape when viewed from above, as in the first embodiment. However, the lengths Wa and Wb in the short side direction of the convex portions 41Aa and 41Ab are different. Further, the arrangement of the convex portions 41Aa and 41Ab is also different from that of the first embodiment, and in this embodiment, the four convex portions 41Aa and 41Ab arranged in a cross shape are at the center point O of the arrangement. They are arranged in a positional relationship that is offset by a predetermined distance Da-Dd. The offset distances Da-Dd may be different from each other or in combination, or may be unified. The rest of the configuration is the same as that of the first embodiment, and the subscript “A” is added to the reference numerals for the portions corresponding to the first embodiment of the respective portions constituting the anti-slip processing portion 40A. Description is omitted.

このように、複数の凸部で滑り止め加工部を構成する場合、各凸部の寸法や配置は適宜設計変更可能である。本例では短辺寸法の異なる２種類の凸部を２つずつ組み合わせて滑り止め加工部４０Ａを構成する場合を例に挙げたが、長辺寸法に変化を付けても良いし、寸法の異なる３種類以上の凸部を組み合わせても良い。凸部の数も４つに限定されず、３つ以下にすることもできるし５つ以上にすることもできる。本実施の形態においても第１の実施の形態と同様の効果を得ることができる。   As described above, when the anti-slip portion is configured by a plurality of convex portions, the dimensions and arrangement of the convex portions can be appropriately changed in design. In this example, the case where the anti-slip processed portion 40A is configured by combining two types of convex portions having different short side dimensions two by one has been described as an example, but the long side dimension may be changed or the dimensions may be different. You may combine 3 or more types of convex parts. The number of convex portions is not limited to four, and can be three or less, or five or more. Also in this embodiment, the same effect as in the first embodiment can be obtained.

（第３の実施の形態）
図１９は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第３の実施の形態を構成する滑り止め加工部の単体の拡大平面図である。 (Third embodiment)
FIG. 19 is an enlarged plan view of a single non-slip processing portion constituting the third embodiment of the anti-slip structure of the load receiving platform of the vehicle load receiving lifting device according to the present invention.

図１９に示すように、本実施の形態の滑り止め加工部４０Ｂの単体は、凸部４１Ｂが第１の実施の形態と同じように上方から見て概略矩形に形成されているが、平行に配置された２つ１組の凸部４１Ｂで構成される２組の凸部対４８Ｂａ，４８Ｂｂを、一方の凸部対４８Ｂａが他方の凸部対４８Ｂｂに対して９０度回転させた状態で並べて配置して構成されている。凸部対４８Ｂａ，４８Ｂｂの数や角度、凸部対４８Ｂａ，４８Ｂｂを構成する凸部４１Ｂの数や寸法は図示した態様に限定されない。それ以外の構成は第１の実施の形態と同様であり、滑り止め加工部４０Ｂを構成する各部のうち第１の実施の形態に対応する部分には符号に添え字「Ｂ」を付して説明を省略する。   As shown in FIG. 19, the non-slip processing portion 40B according to the present embodiment has a convex portion 41B formed in a substantially rectangular shape as viewed from above, as in the first embodiment. Two pairs of convex portions 48Ba and 48Bb composed of two pairs of convex portions 41B are arranged side by side with one convex portion pair 48Ba rotated 90 degrees with respect to the other convex portion pair 48Bb. It is arranged and configured. The number and angle of the convex pairs 48Ba and 48Bb and the number and dimensions of the convex portions 41B constituting the convex pairs 48Ba and 48Bb are not limited to the illustrated modes. The rest of the configuration is the same as that of the first embodiment, and the subscript “B” is added to the reference numerals for the portions corresponding to the first embodiment among the components constituting the anti-slip processing portion 40B. Description is omitted.

本実施の形態のような構成としても、第１の実施の形態と同様の効果を得ることができる。   Even with the configuration of the present embodiment, the same effects as those of the first embodiment can be obtained.

（第４の実施の形態）
図２０は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第４の実施の形態を構成する滑り止め加工部の単体の拡大平面図である。 (Fourth embodiment)
FIG. 20 is an enlarged plan view of a single non-slip processing portion constituting the fourth embodiment of the anti-slip structure of the load receiving table of the vehicle load receiving lifting device of the present invention.

図２０に示すように、本実施の形態の滑り止め加工部４０Ｃの単体は、凸部４１Ｃが第１の実施の形態と同じように上方から見て概略矩形に形成されているが、数を増やして凸部４１Ｃを放射状に８つ配置して構成されている。それ以外の構成は第１の実施の形態と同様であり、滑り止め加工部４０Ｃを構成する各部のうち第１の実施の形態に対応する部分には符号に添え字「Ｃ」を付して説明を省略する。   As shown in FIG. 20, in the non-slip processing portion 40C according to the present embodiment, the convex portion 41C is formed in a substantially rectangular shape when viewed from above as in the first embodiment. The number of convex portions 41C is increased and eight are arranged radially. The rest of the configuration is the same as that of the first embodiment, and the subscript “C” is added to the reference numerals for the portions corresponding to the first embodiment among the components constituting the anti-slip processing portion 40C. Description is omitted.

本実施の形態のような構成でも、第１の実施の形態と同様の効果が得られる。さらに、第１の実施の形態では４つの凸部４１を十文字に配列したため、凸部４１のエッジ部分が直交する２方向を向くようになっていたが、本例の場合、中心点Ｏの周りに等間隔で８つの凸部４１Ｃを配列することにより、前後方向に対して４５度傾斜した「前右・後左」方向と「前左・後右」方向を向いたエッジ部分が加わる。これにより第１の実施の形態よりも効果的に各方向に対する滑り止め効果が発揮される。   Even with the configuration of the present embodiment, the same effects as those of the first embodiment can be obtained. Furthermore, in the first embodiment, since the four convex portions 41 are arranged in a cross shape, the edge portions of the convex portions 41 are directed in two directions orthogonal to each other, but in this example, around the center point O By arranging the eight convex portions 41C at equal intervals, edge portions that are inclined at 45 degrees with respect to the front-rear direction and facing the “front right / rear left” direction and the “front left / rear right” direction are added. Thereby, the anti-slip effect with respect to each direction is exhibited more effectively than in the first embodiment.

（第５の実施の形態）
図２１は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第５の実施の形態を構成する滑り止め加工部の単体の拡大平面図、図２２は図２１中のXXII−XXII断面による断面図である。 (Fifth embodiment)
FIG. 21 is an enlarged plan view of a single non-slip processing portion constituting the fifth embodiment of the anti-slip structure of the load cradle of the vehicle cradle lifting / lowering device of the present invention, and FIG. 22 is a XXII-XXII in FIG. It is sectional drawing by a cross section.

図２１及び図２２に示すように、本実施の形態の滑り止め加工部４０Ｄは、単一の凸部４１Ｄで構成されている。凸部４１Ｄは、ブリッジ部４３Ｄが上方から見て放射状に形成されている点がこれまでの実施の形態と相違している。放射状に形成されたブリッジ部４３Ｄは、その中心点Ｏから四方に延びる延在部４９Ｄを有している。４つの延在部４９Ｄはブリッジ部４３Ｄの中央部分で繋がっており、各延在部４９Ｄの先端部が基部４２Ｄになっている。勿論、ブリッジ部４３Ｄの上面は全体に平坦な荷受面部４４Ｄを構成している。既述した実施の形態では、凸部の形状が矩形になっていたが、このように凸部の形状は適宜設計変更可能である。但し、前述したように十分な剛性を確保するため、ブリッジ部は少なくとも１対の基部を有している必要がある。   As shown in FIG.21 and FIG.22, the anti-slip | skid process part 40D of this Embodiment is comprised by the single convex part 41D. The convex portion 41D is different from the previous embodiments in that the bridge portion 43D is formed radially when viewed from above. The radially formed bridge portion 43 </ b> D has an extending portion 49 </ b> D extending from the center point O in all directions. The four extending portions 49D are connected at the central portion of the bridge portion 43D, and the distal end portion of each extending portion 49D is a base portion 42D. Of course, the upper surface of the bridge portion 43D constitutes a flat load receiving surface portion 44D as a whole. In the embodiment described above, the shape of the convex portion is rectangular, but the shape of the convex portion can be appropriately changed in design in this way. However, as described above, in order to ensure sufficient rigidity, the bridge portion needs to have at least one pair of base portions.

さらに、本実施の形態では、ブリッジ部４３Ｄの荷受面部４４Ｄに各剪断面４６Ｄに沿って形成された溝である４つの凹部５０Ｄを設けている。これにより荷受面部４４Ｄ自体の摩擦係数を高めることができ、より滑り止め効果を向上させることができる。但し、凹部５０Ｄの数や形状は限定されず、例えば比較的大きな円状の凹部を荷受面部４４Ｄに１つ設けても良いし、比較的小さな円状の凹部を多数斑点状に設けても良い。   Further, in the present embodiment, four concave portions 50D that are grooves formed along the respective shear surfaces 46D are provided in the load receiving surface portion 44D of the bridge portion 43D. Thereby, the friction coefficient of the cargo receiving surface portion 44D itself can be increased, and the anti-slip effect can be further improved. However, the number and shape of the recesses 50D are not limited. For example, one relatively large circular recess may be provided on the load receiving surface 44D, or many relatively small circular recesses may be provided in a spot shape. .

上記以外の構成は第１の実施の形態と同様であり、滑り止め加工部４０Ｄを構成する各部のうち第１の実施の形態に対応する部分には符号に添え字「Ｄ」を付して説明を省略する。   The configuration other than the above is the same as that of the first embodiment, and the subscript “D” is added to the reference numerals for the portions corresponding to the first embodiment among the components constituting the anti-slip processing portion 40D. Description is omitted.

（第６の実施の形態）
図２３は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第６の実施の形態を構成する滑り止め加工部の単体の拡大平面図である。 (Sixth embodiment)
FIG. 23 is an enlarged plan view of a single non-slip processing portion constituting a sixth embodiment of the anti-slip structure of the load receiving platform of the vehicle load receiving lifting device of the present invention.

図２３に示すように、本実施の形態の滑り止め加工部４０Ｅは、第５の実施の形態と同様、単一の凸部４１Ｅで構成されているが、上方から見て放射状に形成されたブリッジ部４３Ｅは、その中心点Ｏから八方に延びる延在部４９Ｅを有している。その他の構成は第５の実施の形態と同様であり、滑り止め加工部４０Ｅを構成する各部のうち第５の実施の形態に対応する部分は符号の添え字を「Ｅ」に変えて説明を省略する。   As shown in FIG. 23, the anti-slip processing portion 40E of the present embodiment is configured by a single convex portion 41E as in the fifth embodiment, but is formed radially when viewed from above. The bridge portion 43E has an extending portion 49E extending from the center point O in all directions. The rest of the configuration is the same as that of the fifth embodiment, and the part corresponding to the fifth embodiment of the respective parts constituting the anti-slip processing part 40E is described by changing the subscript to “E”. Omitted.

本実施の形態おいては、第５の実施の形態と同様の効果に加え、延在部４９Ｅを八方に延ばしたことにより、第５の実施の形態と比較してもより効果的に各方向に対する滑り止め効果が発揮される。   In the present embodiment, in addition to the same effects as those of the fifth embodiment, the extending portion 49E is extended in all directions, so that each direction can be more effectively compared with the fifth embodiment. Anti-slip effect is exhibited.

（第７の実施の形態）
図２４は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第７の実施の形態を構成する滑り止め加工部の単体の拡大平面図である。 (Seventh embodiment)
FIG. 24 is an enlarged plan view of a single anti-slip portion constituting the seventh embodiment of the anti-slip structure of the load cradle of the vehicle load cradle lifting device according to the present invention.

第５及び第６の実施の形態では少なくとも１つの凹部５０Ｄ，５０Ｅを有することを特徴としていたが、こうした凹部は放射状に形成したブリッジ部でなくとも設けられることは言うまでもない。ブリッジ部の荷受面部にはその形状とは無関係に凹部を設けることが可能であり、それぞれ相応の効果を得ることができる。図２４に例示した滑り止め加工部４０Ｆは、第１の実施の形態のように概略矩形の凸部４１Ｆの荷受面部４４Ｆに凹部５０Ｆを設けた例である。勿論、同じ矩形の凸部を有する第２−第４の実施の形態や後述する各実施の形態にも凹部を設けることは可能である。その他の構成は既述の実施の形態と同様であり、本実施の形態においても同様の効果を得ることができる。   The fifth and sixth embodiments are characterized by having at least one concave portion 50D, 50E, but it goes without saying that such a concave portion is provided even if it is not a radial bridge portion. It is possible to provide a recess in the load receiving surface portion of the bridge portion regardless of its shape, and it is possible to obtain a corresponding effect. The anti-slip processing part 40F illustrated in FIG. 24 is an example in which a concave part 50F is provided on the load receiving surface part 44F of the substantially rectangular convex part 41F as in the first embodiment. Of course, it is possible to provide a recess also in the second to fourth embodiments having the same rectangular protrusion or in each embodiment described later. Other configurations are the same as those of the above-described embodiment, and the same effect can be obtained in this embodiment.

なお、滑り止め加工部４０Ｆを構成する各部のうち既述の実施の形態に対応する部分は符号の添え字を「Ｆ」に変えて説明を省略した。   Of the parts constituting the anti-slip processing part 40F, the part corresponding to the above-described embodiment is not described by changing the subscript to “F”.

（第８の実施の形態）
図２５は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第８の実施の形態を構成する滑り止め加工部の凸部の拡大平面図である。 (Eighth embodiment)
FIG. 25 is an enlarged plan view of the convex portion of the anti-slip processing portion constituting the eighth embodiment of the anti-slip structure of the load cradle of the vehicle cradle lifting device of the present invention.

上方から見た凸部の形状が矩形に限定されないことは第５及び第６の実施の形態で説明したが、第５及び第６の実施の形態に比して金型の製作容易性の面では、図２５に示したように上方から見て台形状の凸部４１Ｇが有利な例として挙げられる。本例では台形の上底部と下底部を１対の基部４２Ｇ（上底部と下底部を結ぶ２つの側面を剪断面４６Ｇ）としたが、上底部と下底部を結ぶ２つの側面を１対の基部４２Ｇ（上底部と下底部を剪断面４６Ｇ）としても良い。このように１対の基部は形状や長さが異なっても構わない。例えば、基部の形状は１本の直線でなく折れ線や曲線であっても良い。   Although it has been described in the fifth and sixth embodiments that the shape of the convex portion seen from above is not limited to a rectangle, the mold is easier to manufacture than the fifth and sixth embodiments. Then, as shown in FIG. 25, a trapezoidal convex portion 41 </ b> G viewed from above is an advantageous example. In this example, the upper base and lower base of the trapezoid are a pair of bases 42G (the two side surfaces connecting the upper base and the lower base are shear surfaces 46G), but the two side surfaces connecting the upper base and the lower base are a pair. It is good also as base 42G (an upper bottom part and a lower bottom part are the shearing surfaces 46G). In this way, the pair of base portions may have different shapes and lengths. For example, the shape of the base may be a broken line or a curve instead of a single straight line.

凸部４１Ｇは、単独で滑り止め加工部を構成しても良いし、複数で滑り止め加工部を構成しても良い。勿論、上方から見た形状が異なる他の凸部と組み合わせて１つの滑り止め加工部を構成しても良い。これは既述の各実施の形態及び後述の各実施の形態においても同様である。また、凸部４１Ｇとして線対称の台形（上底部及び下底部の挟角が同じ台形）を図示したが、凸部はこのような線対称の台形でなくても良いし、例えば平行四辺形であっても金型の製作は容易である。   The convex portion 41G may constitute a non-slip processed portion alone or a plurality of anti-slip processed portions. Of course, you may comprise one anti-slip | skid processed part combining with the other convex part from which the shape seen from upper direction differs. The same applies to each of the above-described embodiments and each of the embodiments described later. In addition, although a line-symmetric trapezoid (a trapezoid having the same angle between the upper and lower bases) is illustrated as the convex portion 41G, the convex portion may not be such a line-symmetric trapezoid, for example, a parallelogram. Even so, the mold can be easily manufactured.

その他の構成は既述の実施の形態と同様であり、凸部４１Ｇを構成する各部のうち既述の実施の形態に対応する部分は符号の添え字を「Ｇ」に変えて説明を省略した。本実施の形態においても同様の効果を得ることができる。   Other configurations are the same as those of the above-described embodiment, and the portions corresponding to the above-described embodiment among the portions constituting the convex portion 41G are changed to the suffix “G” to omit the description. . Similar effects can be obtained in the present embodiment.

（第９の実施の形態）
図２６は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第９の実施の形態を構成する滑り止め加工部の凸部の拡大平面図である。 (Ninth embodiment)
FIG. 26 is an enlarged plan view of a convex portion of a non-slip processing portion constituting a ninth embodiment of the anti-slip structure of the load receiving table of the vehicle load receiving lifting device of the present invention.

本例は第８の実施の形態と同様に金型の製作容易性の面で有利な他の例であって、図２６に示したように本実施の形態の凸部４１Ｈは、上方から見た形状が概略樽型になっている。基部の形状が１本の直線でなく折れ線や曲線であっても良いことは第８の実施の形態でも述べたが、このことは基部のみならず剪断面にも言えることであり、例えば本実施の形態のように上方から見て外側に凸の曲線に形成された剪断面４６Ｈを持つ構成としても良い。つまり剪断面は曲面であっても良い。また、対向する２つの剪断面の形状や長さが異なっていても構わない。   This example is another example that is advantageous in terms of the ease of manufacturing the mold as in the case of the eighth embodiment. As shown in FIG. 26, the convex portion 41H of the present embodiment is viewed from above. The shape is roughly barrel-shaped. As described in the eighth embodiment, the shape of the base may be not a single straight line but a broken line or a curve. This is true not only for the base but also for the shear plane. It is good also as a structure which has the shearing surface 46H formed in the convex curve outside seeing from upper direction like this form. That is, the shear surface may be a curved surface. Moreover, the shape and length of two opposing shearing surfaces may be different.

このように上方から見た剪断面の形状を一直線とせずに折れ線や曲線とすることで、１つの剪断面でありながら複数方向に対する滑り止め効果を発揮することができる。   Thus, by making the shape of the shearing surface viewed from above not a straight line but a broken line or a curved line, it is possible to exhibit an anti-slip effect in a plurality of directions while being one shearing surface.

その他の構成は既述の実施の形態と同様であり、凸部４１Ｈを構成する各部のうち既述の実施の形態に対応する部分は符号の添え字を「Ｈ」に変えて説明を省略した。本実施の形態においても同様の効果を得ることができる。   The other configurations are the same as those of the above-described embodiment, and the portions corresponding to the above-described embodiment among the portions constituting the convex portion 41H are changed by substituting the suffix of the reference sign to “H” and the description is omitted. . Similar effects can be obtained in the present embodiment.

（第１０の実施の形態）
図２７は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第１０の実施の形態を構成する滑り止め加工部の凸部の拡大平面図である。 (Tenth embodiment)
FIG. 27 is an enlarged plan view of the convex portion of the anti-slip processing portion constituting the tenth embodiment of the anti-slip structure of the load cradle of the vehicle cradle lifting device of the present invention.

図２７に示したように、本実施の形態も上方から見た剪断面の形状を曲線とした他の例を示したもので、本実施の形態の凸部４１Ｉの剪断面４６Ｉは上方から見て内側に凸状（すなわち凹状）に形成されている。また、対向する２つの剪断面の形状や長さが異なっていても構わない。   As shown in FIG. 27, this embodiment also shows another example in which the shape of the shearing surface seen from above is a curve, and the shearing surface 46I of the convex portion 41I of this embodiment is seen from above. Inwardly, it is formed in a convex shape (that is, a concave shape). Moreover, the shape and length of two opposing shearing surfaces may be different.

その他の構成は第９の実施の形態と同様であり、凸部４１Ｉを構成する各部のうち既述の実施の形態に対応する部分は符号の添え字を「Ｉ」に変えて説明を省略した。本実施の形態においても同様の効果を得ることができる。   Other configurations are the same as those of the ninth embodiment, and the portions corresponding to the above-described embodiment of the respective portions constituting the convex portion 41I have been replaced with “I” as reference numerals, and description thereof has been omitted. . Similar effects can be obtained in the present embodiment.

（第１１の実施の形態）
図２８は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第１１の実施の形態を構成する滑り止め加工部の凸部の斜視図である。 (Eleventh embodiment)
FIG. 28 is a perspective view of the convex portion of the anti-slip processing portion constituting the eleventh embodiment of the anti-slip structure of the load receiving table of the vehicle load receiving lifting device of the present invention.

既述の各実施の形態では、ブリッジ部の上面に荷受台５の荷受面とほぼ平行な荷受面部を設けることにより、荷受台５に載置された荷物等の底部に加わる面圧を極力低下させる効果を狙ったが、例えば、ダンボール箱をあまり扱わない、又は段ボール箱を荷受台５上に置く作業を殆どしないユーザ等、荷物の概観の保護よりも極力滑り止め効果の高い荷受面を重視するユーザもいる。既述の実施の形態では、剪断面を有する凸部を形成しその剪断面の上部にエッジを立てることで高い滑り止め効果を確保したが、ブリッジ部の上面の形状を工夫することによって更なる滑り止め効果も期待できる。   In each of the embodiments described above, the surface pressure applied to the bottom of the load placed on the load receiving platform 5 is reduced as much as possible by providing a load receiving surface portion substantially parallel to the load receiving surface of the load receiving platform 5 on the upper surface of the bridge portion. However, for example, users who do not handle cardboard boxes very much or who rarely work on placing cardboard boxes on the receiving platform 5 place importance on the receiving surface that has a higher anti-slip effect than the protection of the appearance of the luggage. Some users do. In the embodiment described above, a high anti-slip effect was ensured by forming a convex part having a shearing surface and raising an edge on the upper part of the shearing surface. However, by further devising the shape of the upper surface of the bridge part. Anti-slip effect can be expected.

図２８に示した凸部４１Ｊは、山型にブリッジ部４３Ｊを形成して構成されており、側方から見て剪断面４６Ｊの頂部に角張ったエッジ状の頂部５２Ｊが形成されている。こうすることで剪断面４６Ｊの上縁部のエッジに加えて上面の頂部５２Ｊのエッジが相乗し、さらなる滑り止め効果の向上が期待できる。このように、凸部は上方から見た形状だけでなく、側方から見た形状も適宜設計変更可能である。勿論、凸部４１Ｊは、単独で滑り止め加工部を構成しても良いし、複数で滑り止め加工部を構成しても良い。側方又は上方から見た形状が異なる他の凸部と組み合わせて１つの滑り止め加工部を構成しても良いことも言うまでもない。また、本例では凸部４１Ｊが単純に上に凸に形成されているが、変曲して一部凹むように形成し、上面に複数のエッジが立つようにしても良い。   The convex portion 41J shown in FIG. 28 is configured by forming a bridge portion 43J in a mountain shape, and an edge-like top portion 52J is formed at the top portion of the shearing surface 46J when viewed from the side. By doing so, in addition to the edge of the upper edge portion of the shear surface 46J, the edge of the top portion 52J of the upper surface is synergistic, and further improvement of the anti-slip effect can be expected. Thus, not only the shape of the convex portion seen from above but also the shape seen from the side can be appropriately changed in design. Of course, the convex portion 41J may constitute a non-slip processed portion alone, or a plurality of anti-slip processed portions. Needless to say, one anti-slip portion may be configured in combination with other convex portions having different shapes as viewed from the side or from above. Further, in this example, the convex portion 41J is simply formed to be convex upward, but it may be formed so as to be bent and partially concave so that a plurality of edges stand on the upper surface.

また、上方から見ると頂部５２Ｊである上面のエッジ部が剪断面４６Ｊに交差する直線になっているが、これは曲線状に形成されていても良いし、基部４２Ｊに交差する直線又は曲線としても良い。互いに交差する複数のエッジ部を有するようにしても良い。この場合、頂部５２Ｊは線でなく点になる。点で滑り止め効果を狙うなら、頂部５２Ｊを線状でなく点状に形成しても良い。   Further, when viewed from above, the edge portion of the top surface, which is the top portion 52J, is a straight line that intersects the shear plane 46J, but this may be formed in a curved shape, or as a straight line or a curve that intersects the base portion 42J. Also good. You may make it have several edge part which mutually cross | intersects. In this case, the top 52J is not a line but a point. If the anti-slip effect is aimed at the point, the top portion 52J may be formed in a dot shape instead of a linear shape.

その他の構成は既述の実施の形態と同様であり、凸部４１Ｊを構成する各部のうち既述の実施の形態に対応する部分は符号の添え字を「Ｊ」に変えて説明を省略した。   The other configurations are the same as those of the above-described embodiment, and the portions corresponding to the above-described embodiment among the respective portions constituting the convex portion 41J are changed by substituting “J” for the reference numerals, and the description thereof is omitted. .

（第１２の実施の形態）
図２９は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第１２の実施の形態を構成する滑り止め加工部の凸部の斜視図である。 (Twelfth embodiment)
FIG. 29 is a perspective view of the convex portion of the anti-slip processing portion constituting the twelfth embodiment of the anti-slip structure of the load cradle of the vehicle cradle lifting device of the present invention.

本実施の形態は、第１１の実施の形態の角張った頂部５２Ｊに丸み（アール）をつけた例である。すなわち。図２９に示した凸部４１Ｋも山型にブリッジ部４３Ｋを形成して構成されているが、側方から見て剪断面４６Ｋの頂部に丸みを帯びたアール状の頂部５２Ｋが形成されている。このようにすることで、第１−第１０の実施の形態等のように凸部の上面に荷受面部を形成した場合に比べても上面が山型であることにより滑り止め効果が増し、なおかつ頂部５２Ｋにアールをつけたことによって第１１の実施の形態に比べて、上に置かれる荷物の底面にかかる面圧を下げることができる。また、本例でも凸部４１Ｋは単純に上に凸に形成されているが、変曲して一部凹むように形成しても良い。   The present embodiment is an example in which the angular top 52J of the eleventh embodiment is rounded. That is. The convex portion 41K shown in FIG. 29 is also formed by forming a bridge portion 43K in a mountain shape, but a rounded round top 52K is formed at the top of the shearing surface 46K when viewed from the side. . By doing in this way, compared with the case where the load receiving surface portion is formed on the upper surface of the convex portion as in the first to tenth embodiments, the anti-slip effect is increased because the upper surface is mountain-shaped, and Compared with the eleventh embodiment, the surface pressure applied to the bottom surface of the load placed on the top 52K can be lowered. Also, in this example, the convex portion 41K is simply convex upward, but it may be formed so as to be partially bent due to inflection.

その他の構成は既述の実施の形態と同様であり、凸部４１Ｋを構成する各部のうち既述の実施の形態に対応する部分は符号の添え字を「Ｋ」に変えて説明を省略した。   Other configurations are the same as those of the above-described embodiment, and the portions corresponding to the above-described embodiment among the respective portions constituting the convex portion 41K are changed by substituting the suffix of the reference sign to “K” and the description is omitted. .

（第１３の実施の形態）
図３０は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第１３の実施の形態を構成する滑り止め加工部の凸部の斜視図である。 (Thirteenth embodiment)
FIG. 30 is a perspective view of the convex portion of the anti-slip processing portion constituting the thirteenth embodiment of the anti-slip structure of the load receiving platform of the vehicle load receiving lifting device of the present invention.

既述の実施の形態では、凸部の上面が荷受面部であるか滑り止め形状であるかに関わらず、平坦な面を有していた。凸部の上面の形状（凸部の側方から見た形状）が適宜設計変更可能であることが既に述べた通りで、当然ながら上面が曲面であっても構わない。   In the above-described embodiment, the upper surface of the convex portion has a flat surface regardless of whether it is a load receiving surface portion or a non-slip shape. As described above, the design of the shape of the upper surface of the convex portion (the shape viewed from the side of the convex portion) can be changed as appropriate. Naturally, the upper surface may be a curved surface.

本実施の形態の凸部４１Ｌは山型にブリッジ部４３Ｌを形成して構成されてはいるが、側方から見て剪断面４６Ｌは全体に弧状に形成されており、凸部４１Ｌの上面５３Ｌは全体に（全面が）曲面で形成されている。本例では上面５３Ｌが単純に上に凸の形状をしているが、変曲して一部凹むように形成しても良い。勿論、線状に凹む形状に限らず点状に（ある箇所が）凹む形状であっても良い。   Although the convex portion 41L of the present embodiment is formed by forming a bridge portion 43L in a mountain shape, the shear surface 46L is formed in an arc shape as viewed from the side, and the upper surface 53L of the convex portion 41L. Is entirely (entirely) formed with a curved surface. In this example, the upper surface 53L simply has a convex shape upward, but may be formed so as to be bent and partially recessed. Needless to say, the shape is not limited to a linearly recessed shape, and may be a shape that is recessed in a dotted shape (a certain portion).

その他の構成は既述の実施の形態と同様であり、凸部４１Ｌを構成する各部のうち既述の実施の形態に対応する部分は符号の添え字を「Ｌ」に変えて説明を省略した。   Other configurations are the same as those of the above-described embodiment, and the portions corresponding to the above-described embodiment among the respective portions constituting the convex portion 41L are not described by changing the subscripts to “L”. .

（第１４の実施の形態）
図３１は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第１４の実施の形態を構成する滑り止め加工部のうち近隣の複数のものを抽出した拡大平面図である。 (Fourteenth embodiment)
FIG. 31 is an enlarged plan view in which a plurality of neighboring non-slip processing portions constituting the fourteenth embodiment of the anti-slip structure of the load receiving table of the vehicle load receiving lifting device of the present invention are extracted.

前述した実施の形態に係る滑り止め構造では、図４に示したように同じ大きさの滑り止め加工部を同じ向きに複数配列して構成したが、滑り止め加工部は、同じ荷受台の荷受面に設けるものであっても、大きさ・向きとも不揃いであって構わない。   In the anti-slip structure according to the above-described embodiment, as shown in FIG. 4, a plurality of the same size non-slip processed parts are arranged in the same direction. Even if it is provided on the surface, the size and direction may be uneven.

図３１に示した滑り止め構造は、互いの向きが４５度異なる２種類の滑り止め加工部４０，４０Ｇを荷受面に複数配置した例である。滑り止め加工部４０は第１の実施の形態の滑り止め加工部であり、滑り止め加工部４０Ｇは滑り止め加工部４０を４５度回転させた構成のものである。また、滑り止め加工部４０ａ，４０Ｇａは、滑り止め加工部４０，４０Ｇを相似的に縮小した構成のものである。勿論、第２−第７の実施の形態で例示した滑り止め加工部のような、その他の形状の滑り止め加工部を同じ荷受面に設けるもの同士で大きさや角度（４５度に限定されない）を適宜異ならせて配列し、滑り止め構造をなしても良い。言うまでもないが、同一の荷受面上に設ける滑り止め加工部は、大きさ・向きの双方を異ならせずいずれか一方だけを異ならせても良い。   The anti-slip structure shown in FIG. 31 is an example in which a plurality of two types of anti-slip processed parts 40 and 40G whose directions differ from each other by 45 degrees are arranged on the load receiving surface. The anti-slip processing unit 40 is the anti-slip processing unit of the first embodiment, and the anti-slip processing unit 40G is configured by rotating the anti-slip processing unit 40 by 45 degrees. Further, the anti-slip processing parts 40a and 40Ga have a configuration in which the anti-slip processing parts 40 and 40G are similarly reduced. Needless to say, the size and angle (not limited to 45 degrees) of the non-slip processed parts exemplified in the second to seventh embodiments are provided on the same load receiving surface. They may be arranged as appropriate to form a non-slip structure. Needless to say, the non-slip processed portions provided on the same load receiving surface may be different in only one of them without changing the size and the direction.

（第１５の実施の形態）
図３２は本考案の車両用荷受台昇降装置の荷受台の滑り止め構造の第１５の実施の形態を構成する滑り止め加工部のうち近隣の複数のものを抽出した拡大平面図である。 (Fifteenth embodiment)
FIG. 32 is an enlarged plan view in which a plurality of neighboring non-slip processing portions constituting the fifteenth embodiment of the anti-slip structure of the load receiving platform of the vehicle load receiving lifting device of the present invention are extracted.

前述した実施の形態に係る滑り止め構造では、図４に示したように同じ構成の滑り止め加工部を複数配列して構成したが、滑り止め加工部は、同じ荷受台の荷受面に設けるものであっても構成が不揃いであって構わない。   In the anti-slip structure according to the above-described embodiment, a plurality of anti-slip processing parts having the same configuration are arranged as shown in FIG. 4, but the anti-slip processing parts are provided on the load receiving surface of the same load receiving platform. However, the configuration may be uneven.

図３２に示した滑り止め構造は、既述の実施の形態の滑り止め加工部のうちの４種類を同じ荷受面に複数配置した例である。滑り止め加工部４０は第１の実施の形態の滑り止め加工部、滑り止め加工部４０Ａは第２の実施の形態の滑り止め加工部、滑り止め加工部４０Ｂは第３の実施の形態の滑り止め加工部、滑り止め加工部４０Ｅは第６の実施の形態の滑り止め加工部である。勿論、その他の実施の形態で例示した滑り止め加工部を同じ荷受面に設けても良いし、種類も４種類に限らず、３種類以下でも５種類以上でも良い。また、第１４の実施の形態のように同一荷受面上の各滑り止め加工部の向きや大きさを適宜異ならせても良い。   The anti-slip structure shown in FIG. 32 is an example in which a plurality of four types of anti-slip processing parts of the above-described embodiment are arranged on the same load receiving surface. The anti-slip processing unit 40 is the anti-slip processing unit of the first embodiment, the anti-slip processing unit 40A is the anti-slip processing unit of the second embodiment, and the anti-slip processing unit 40B is the anti-slip processing unit of the third embodiment. The stop processing portion and the anti-slip processing portion 40E are the anti-slip processing portion of the sixth embodiment. Of course, the non-slip processed parts exemplified in the other embodiments may be provided on the same load receiving surface, and the types are not limited to four, and may be three or less or five or more. Further, as in the fourteenth embodiment, the directions and sizes of the anti-slip processed portions on the same load receiving surface may be appropriately changed.

このように、既述した各実施の形態を含めて本考案の技術的思想の範囲内にある滑り止め加工部は適宜組合せ可能であり、組み合わせることで対応の効果を発揮させることができる。各滑り止め加工部の配列も図４に示したような規則的な態様に限定されず、ランダムな配列としても良い。荷受面上の場所により荷物や作業者の積載・往来の頻度に差がある場合、それに応じて滑り止め加工部の疎密に変化を付けた複数の領域を同一荷受面上に設けても良いし、滑り止め加工部を設けずに基面４５のみで構成する領域を設けても良い。   As described above, the anti-slip processing parts within the scope of the technical idea of the present invention including each of the embodiments described above can be appropriately combined, and the corresponding effect can be exhibited by combining them. The arrangement of the anti-slip processing portions is not limited to the regular form as shown in FIG. 4 and may be a random arrangement. If there is a difference in the load / traffic frequency of loads and workers depending on the location on the load receiving surface, multiple areas with varying density of the anti-slip processing part may be provided on the same load receiving surface accordingly. Alternatively, a region constituted only by the base surface 45 may be provided without providing the anti-slip processing part.

なお、以上の各実施の形態においては、格納時や展開時に荷受台５を前後にスライドさせる手段としてスライドシリンダ１４を例に挙げて説明したが、シリンダに限らず、例えばモータ等といった他のアクチュエータを用いても良いし、手動によって荷受台５をスライドさせるようにしても構わない。また、油圧アクチュエータに限らず電動アクチュエータに代えても構わない。リフトシリンダ２２に関しても、シリンダに限らず、例えばモータ等といった他のアクチュエータを用いても良いし、油圧アクチュエータに限らず電動アクチュエータに代えても構わない。   In each of the above-described embodiments, the slide cylinder 14 has been described as an example of means for sliding the load receiving platform 5 back and forth during storage and deployment. However, the present invention is not limited to the cylinder, and other actuators such as a motor, for example. Alternatively, it may be possible to manually slide the load receiving platform 5. Further, the actuator is not limited to a hydraulic actuator, and may be replaced with an electric actuator. The lift cylinder 22 is not limited to the cylinder, and other actuators such as a motor may be used. The lift cylinder 22 may be replaced with an electric actuator without being limited to a hydraulic actuator.

また、荷受台基端部２３の荷受面に本考案を適用した場合を説明したが、荷受台本体部２５や荷受台先端部２７の荷受面にも本考案は適用可能である。また、３つ折りの荷受台５の荷受面に本考案を適用した場合を例に挙げて説明したが、２つ折り若しくは４つ折り以上の折り畳み構造の荷受台又は折り畳み構造を持たない一枚物の荷受台の荷受面にも本考案は適用可能である。   Moreover, although the case where this invention was applied to the cargo receiving surface of the cargo receiving base base part 23 was demonstrated, this invention is applicable also to the cargo receiving surface of the cargo receiving base main-body part 25 or the cargo receiving stand front-end | tip part 27. In addition, the case where the present invention is applied to the load receiving surface of the three-fold load receiving base 5 has been described as an example, but a two-fold or four-fold or more folded load receiving table or a single-piece load receiving not having the folding structure. The present invention can also be applied to the receiving surface of a table.

また、車両の車枠後部の下部側に収容可能な格納式荷受台昇降装置の荷受台に本考案を適用した場合を例にとって説明したが、他の方式の荷受台昇降装置の荷受台にも適用可能である。荷受台昇降装置には、例えば収容時には荷受台が垂直に起立して車両の荷台の後部側面を構成する一方、作業時には荷受台が水平の状態を保って垂直方向に昇降するタイプのものもある。また、本実施の形態の荷受台昇降装置と同様に平行リンクを介して荷受台を昇降させるものであっても、荷受台を車枠の下部側に収容するのではなく、車両の荷台の後部側面に沿って垂直に起立させる収容姿勢を採るものもある。このように、例えばバン型トラック等の貨物車両の荷台に設けられる荷受台昇降装置用であればその昇降方式や収容方式に制限されることなく本考案は適用可能であり、こうした方式の異なる荷受台昇降装置の荷受台に本考案を適用した場合も上記と同様の効果を得ることができる。   In addition, although the case where the present invention is applied to the load receiving platform of the retractable load receiving platform lifting device that can be accommodated in the lower part of the rear part of the vehicle frame has been described as an example, the present invention is also applied to the load receiving platform of another type of load receiving platform lifting device Is possible. For example, there is a type in which the load receiving stand erects vertically during housing to form the rear side surface of the load receiving platform of the vehicle, while the load receiving stand is moved up and down in the vertical direction while maintaining a horizontal state during work. . Further, even if the load receiving platform is lifted and lowered via the parallel link in the same manner as the load receiving platform lifting device of the present embodiment, the load receiving platform is not housed on the lower side of the vehicle frame, but the rear side surface of the vehicle loading platform. Some take a stowed posture to stand vertically along. Thus, for example, the present invention can be applied to a load receiving platform lifting device provided on the loading platform of a freight vehicle such as a van type truck, without being limited to its lifting method or accommodation method. The same effects as described above can be obtained when the present invention is applied to the load receiving platform of the platform lifting device.

また、車両の後方に設ける荷受台昇降装置の荷受台に本考案を適用した場合を例にとって説明したが、車両の側方（右側又は左側）に設ける荷受台昇降装置の荷受台にも本考案は適用可能である。このような場合でも上記と同様の効果を得ることができる。   Moreover, although the case where this invention was applied to the load receiving stand of the load receiving platform raising / lowering apparatus provided in the back of a vehicle was demonstrated as an example, this invention is also applied to the load receiving stand of the load receiving stand raising / lowering apparatus provided in the side (right side or left side) of a vehicle. Is applicable. Even in such a case, the same effect as described above can be obtained.
