Description
本発明は、船舶内に使用される梯子（ラッタル）、タラップ、脚立、家屋の階段等の昇降具に用いられる踏桟に関する。 The present invention relates to a pedestal used for lifting tools such as ladders, laps, stepladders, and house stairs used in ships.
従来の昇降具としての梯子を図１１を参照して説明する。尚、図１１において、（Ａ）は正面図、（Ｂ）は側面図である。 A ladder as a conventional lifting tool will be described with reference to FIG. In FIG. 11, (A) is a front view and (B) is a side view.
図１１に示すように、梯子は、脚部１０１ａ、１０１ｂと頭部１０２ａ、１０２ｂとの間に結合されたフレーム構造をなす2対の支柱１０３ａ−１、１０３ａ−２（図示せず）、１０３ｂ−１、１０３ｂ−２と、支柱１０３ａ−１、１０３ｂ−１に結合された1対の手摺１０４ａ、１０４ｂと、支柱１０３ａ−１、１０３ａ−２（図示せず）と支柱１０３ｂ−１、１０３ｂ−２との間に等間隔に結合された複数の踏桟１０５とによって構成されている（参照：特許文献１）。 As shown in FIG. 11, the ladder is composed of two pairs of columns 103a-1, 103a-2 (not shown), 103b that form a frame structure coupled between the legs 101a, 101b and the heads 102a, 102b. -1, 103b-2, a pair of handrails 104a, 104b coupled to the columns 103a-1, 103b-1, columns 103a-1, 103a-2 (not shown) and columns 103b-1, 103b- 2 and a plurality of step bars 105 coupled at equal intervals between the two (refer to Patent Document 1).
図１１においては、脚部１０１ａ、１０１ｂは床にねじ止めされた止め具１０６ａ、１０６ｂに回転可能に結合され、他方、頭部１０２ａ、１０２ｂは天井にねじ止めされた止め具１０７ａ、１０７ｂに回転可能に結合され、梯子は急傾斜をなしている。このような梯子は傾斜梯子（ラッタル）と呼ばれ、たとえば、船舶の内部等において昇降に用いられる。 In FIG. 11, the legs 101a, 101b are rotatably coupled to stops 106a, 106b screwed to the floor, while the heads 102a, 102b rotate to stops 107a, 107b screwed to the ceiling. Combined possible, the ladder is steep. Such a ladder is called an inclined ladder and is used for raising and lowering inside a ship, for example.
図１２は図１１の踏桟１０５の斜視図である。すなわち、踏桟１０５は、図示しないボルト等によって図１１の支柱１０３ａ−１、１０３ａ−２；１０３ｂ−１、１０３ｂ−２に固定された金属製の踏み板１０５１と、滑止めマット１０５２とによって構成されている。 FIG. 12 is a perspective view of the crosspiece 105 of FIG. That is, the tram 105 includes a metal foot plate 1051 fixed to the columns 103a-1, 103a-2; 103b-1, 103b-2 in FIG. 11 by bolts (not shown), and a non-slip mat 1052. ing.
踏み板１０５１は、その前端部１０５１ａが内側にほぼ直角に折り曲げられた断面L字形状をなしており、また、滑止めマット１０５２も、その前端部１０５２ａが内側にほぼ直角に折り曲げられた断面L字形状をなしている。滑止めマット１０５２は、エチレンプロプレン（EPDM）ゴムチップ、天然ゴムチップ等を混成した防滑性、弾力性、防音性、透水性、難燃性、耐撃性、耐候性等を有する材料よりなる本体部１０５２−１と、本体部１０５２−２の前端部に積層された合成ゴム等により形成された防滑性、耐摩耗性材料よりなるコーナ部１０５２−２とにより構成されている。尚、コーナ部１０５２−２の一部の表面は、防滑性を増大させるために、凹凸にされている。 The tread plate 1051 has an L-shaped cross section in which the front end portion 1051a is bent inward at a substantially right angle, and the anti-slip mat 1052 also has an L-shaped cross section in which the front end portion 1052a is bent inward at a substantially right angle. It has a shape. Non-slip mat 1052 is a main body made of a material having anti-slip property, elasticity, soundproof property, water permeability, flame resistance, fire resistance, weather resistance, etc., which is a mixture of ethylene propylene (EPDM) rubber chip, natural rubber chip, etc. 1052-1 and a corner portion 1052-2 made of a non-slip, wear-resistant material formed of synthetic rubber or the like laminated on the front end portion of the main body portion 1052-2. Note that a part of the surface of the corner portion 1052-2 is made uneven to increase the slip resistance.
図１３の（Ａ）の組立前側面断面図を参照すると、補強部材としての取付け金具１０５３ａを滑止めマット１０５２の前端部１０５２ａの外側に貼付ける。他方、浮上り防止部材としての取付け金具１０５４ａを滑止めマット１０５２の後端部１０５２ｂの外側に貼付ける。この場合、取付け金具１０５３ａ、１０５４ａの貼付け前もしくは後に、取付け金具１０５３ａ及び踏み板１０５１にねじ１０５３用の位置合わせが必要な矢印Ｈ１、Ｈ１’に示す穴加工すると共に、取付け金具１０５４ａ及び踏み板１０５１にねじ１０５４用の位置合わせが必要な矢印Ｈ２、Ｈ２’に示す穴加工する。 Referring to the cross-sectional side view before assembly in FIG. 13A, a mounting bracket 1053a as a reinforcing member is attached to the outside of the front end portion 1052a of the non-slip mat 1052. On the other hand, a mounting bracket 1054a as an anti-lifting member is attached to the outside of the rear end portion 1052b of the non-slip mat 1052. In this case, before or after attaching the mounting brackets 1053a and 1054a, holes shown in arrows H1 and H1 ′ that need to be aligned for the screws 1053 are formed in the mounting brackets 1053a and the footboards 1051, and screws are attached to the mounting brackets 1054a and the footboards 1051. Drill holes indicated by arrows H2 and H2 ′ that require alignment for 1054.
次に、図１３の（Ｂ）の組立後側面断面図を参照すると、踏み板１０５１の外面と滑止めマット１０５２の内面とを接触させる。次いで、踏み板１０５１の折り曲げられた前端部１０５２ａとを取付け金具１０５３ａの穴及び踏み板１０５１の穴を介してねじ１０５３によって固定する。他方、踏み板１０５１の後端部１０５１ｂと滑止めマット１０５２の後端部１０５２ｂとを取付け金具１０５４ａの穴及び踏み板１０５１の穴を介してねじ１０５４によって固定する。 Next, referring to the assembled side sectional view of FIG. 13B, the outer surface of the tread plate 1051 and the inner surface of the anti-slip mat 1052 are brought into contact with each other. Next, the bent front end portion 1052a of the tread plate 1051 is fixed by the screw 1053 through the hole of the mounting bracket 1053a and the hole of the tread plate 1051. On the other hand, the rear end portion 1051b of the tread plate 1051 and the rear end portion 1052b of the anti-slip mat 1052 are fixed by screws 1054 through the holes of the mounting bracket 1054a and the tread plate 1051.
しかしながら、図１２に示す従来の踏桟においては、踏み板１０５１と滑止めマット１０５２との固定はねじ１０５３、１０５４によって行っているので、取付け金具１０５３ａ、１０５４ａの貼付け、金属製の踏み板１０５１及び取付け金具１０５３ａ、１０５４ａに位置合わせが必要な穴加工を必要とし、この結果、組立作業効率が低いという課題がある。 However, in the conventional foot cross shown in FIG. 12, the tread plate 1051 and the anti-slip mat 1052 are fixed by screws 1053 and 1054, so that the mounting brackets 1053a and 1054a are attached, the metal tread plate 1051 and the mounting bracket. 1053a and 1054a require drilling that requires alignment, resulting in low assembly work efficiency.
上述の課題を解決するために、本発明に係る昇降具用踏桟は、前端部及び後端部が内側にほぼ直角に折り曲げられた断面コ字形状の踏み板と、前端部が内側にほぼ直角に折り曲げられた断面L字形状の滑止めマットとを具備し、踏み板の外面と滑止めマットの内面を接触させ、踏み板の折り曲げられた前端部と滑止めマットの折り曲げられた前端部とを第１のクリップ型取付け金具によって固定し、踏み板の折り曲げられた後端部と滑止めマットの後端部とを第２のクリップ型取付け金具によって固定したものである。 In order to solve the above-described problem, a lifting rail for a lifting tool according to the present invention includes a foot plate having a U-shaped cross section in which a front end portion and a rear end portion are bent at a substantially right angle inside, and a front end portion at a substantially right angle toward the inside. A non-slip mat with an L-shaped cross-section, and the outer surface of the tread plate and the inner surface of the non-slip mat are brought into contact with each other so that the folded front end of the tread plate and the folded front end of the non-slip mat are The rear end portion of the tread plate that is bent and the rear end portion of the anti-slip mat are fixed by a second clip type mounting bracket.
本発明によれば、踏み板と滑止めマットとの固定を、ねじを用いずに、クリップ型取付け金具を用いて行っているので、取付け金具の貼付け及び位置合わせが必要な穴加工が不要となり、組立作業効率を向上できる。 According to the present invention, since the tread plate and the non-slip mat are fixed using the clip-type mounting bracket without using a screw, the hole processing that requires attachment and positioning of the mounting bracket becomes unnecessary. Assembly work efficiency can be improved.
図１は本発明に係る昇降具用踏桟の実施の形態を示斜視図である。 FIG. 1 is a perspective view showing an embodiment of a lifting rail for an elevator according to the present invention.
図１において、踏桟は、図１１の支柱１０３ａ−１、１０３ａ−２；１０３ｂ−１、１０３ｂ−２にボルト等によって固定される金属製の踏み板１と、滑止めマット２とによって構成されている。 In FIG. 1, the crosspiece is composed of a metal tread plate 1 fixed to the columns 103 a-1 and 103 a-2; 103 b-1 and 103 b-2 in FIG. Yes.

In this case as well, a part of the surface of the corner portion 2-2 is made uneven to increase the slip resistance.
踏み板１の前端部１ａと滑止めマット２の前端部２ａとは図２の（Ａ）に示すばね性の3つのクリップ型取付け金具３−１、３−２、３−３によって固定され、他方、踏み板１の後端部１ｂと滑止めマット２の後端部２ｂとは図２の（Ｂ）に示すばね性の3つのクリップ型取付け金具４−１、４−２、４−３によって固定されている。 The front end 1a of the footboard 1 and the front end 2a of the anti-slip mat 2 are fixed by three spring-type clip-type mounting brackets 3-1, 3-2, 3-3 shown in FIG. The rear end portion 1b of the footboard 1 and the rear end portion 2b of the anti-slip mat 2 are fixed by three spring-type clip-type mounting brackets 4-1, 4-2, 4-3 shown in FIG. Has been.
図２の（Ａ）に示すように、クリップ型取付け金具３−１（３−２、３−３）は、断面コ字形状鈎部３ａ、断面コ字形状鈎部３ａの一方側を延伸した平板部３ｂ、及び平板部３ｂの先端に設けられた爪部３ｃにより構成されている。他方、図２の（Ｂ）に示すように、クリップ型取付け金具４−１（４−２、４−３）は、断面V字形状鈎部４ａ、断面V字形状鈎部４ａの一方側を延伸した断面L字形状部４ｂ、及び断面L字形状部４ｂの先端に設けられた爪部４ｃにより構成されている。 As shown in FIG. 2A, the clip-type mounting bracket 3-1 (3-2, 3-3) extends one side of the cross-sectional U-shaped flange 3a and the cross-sectional U-shaped flange 3a. It is comprised by the nail | claw part 3c provided in the front-end | tip of the flat plate part 3b and the flat plate part 3b. On the other hand, as shown in FIG. 2B, the clip-type mounting bracket 4-1 (4-2, 4-3) has one side of the cross-sectional V-shaped flange 4a and the cross-sectional V-shaped flange 4a. The cross section L-shaped portion 4b is extended, and the claw portion 4c is provided at the tip of the cross-sectional L-shaped portion 4b.
以下、図１の踏桟の組立方法を説明する。 Hereinafter, a method for assembling the crosspiece shown in FIG. 1 will be described.
