【考案の詳細な説明】
本考案は、ゴム製防舷材、殊に横長筒形のゴム
製防舷材の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in rubber fenders, particularly oblong cylindrical rubber fenders.
従来、第１図に示すごとく、断面形状が輪形

接頭語を冠して仮称する。 Conventionally, as shown in FIG. 1, rubber fenders having an oblong cylindrical shape and having a trapezoidal cross-sectional shape of a ring shape a, a square shape b, a substantially inverted V shape c, or a substantially inverted Y shape d are known. In this specification, these fenders are tentatively named with prefixes such as "cylindrical,""prismatic,""V-shaped," and "Y-shaped," respectively.

前記補強材料の埋設により剛直化される該防舷材
は反力を増大し、所定の性能を発揮しえなくな
る。 As is well known, the above-mentioned oblong cylindrical fenders are suspended or fixed with anchor bolts so that their axes are parallel to the quay surface, and are mainly caused by the deformation of the rubber body. Alleviates the compressive force applied when the ship docks. As a result, the surface rubber is torn and chipped due to the abrasive action of the ship's side panels (this is called "chipping damage").
). Conventionally, in order to prevent this damage, a technology has been proposed for quite some time to embed reinforcing materials such as woven fabric or scale cord in the surface of the fender and the impact-receiving surface that comes in most contact with the fender side plate ( for example,
Jitko No. 34-17460, Jitko No. 35-3147, etc.). However, as mentioned earlier, rubber fenders absorb impact energy by deforming the fuselage, so
The fender, which is made rigid by embedding the reinforcing material, increases the reaction force and becomes unable to exhibit the desired performance.
一方、ゴム成形品の補強手段としてゴム材料中

り、それだけ反力が増大し所定のエネルギー吸収
性能を発揮し得なくなる。 On the other hand, a technique is well known in which a large number of short fibers are mixed into a rubber material as a reinforcing means for rubber molded products.
Therefore, as a countermeasure against the above-mentioned chipping damage, it is conceivable to construct the required parts of the rubber fender, for example, the impact receiving part, with the rubber material containing short and small fibers, but in this case as well, the short and small fibers may be mixed in. Performance deteriorates because the abutment becomes rigid. For example, the "V-shaped fender" shown in Figure 1 c can exhibit greater energy absorption performance than the "cylindrical fender" and "prismatic cylindrical fender" shown in Figure 1 a and b. It is widely used as a However, in the case of the fender,
After compressive deformation of the rubber occurs at the initial stage of loading, the rubber body bends and deforms as shown in Figure 2 in response to the subsequent compressive load to absorb the compressive energy, but in this case, the impact receiving part also becomes concave as shown in the figure. Deforms into a curved shape. Therefore, if the impact receiving portion is made rigid, the bending action of the left and right side walls will be suppressed, and the reaction force will increase accordingly, making it impossible to exhibit a predetermined energy absorption performance.
そこで、本考案者は防舷材の性能を低下させる

傷に対応できることを見出した。 Therefore, as a result of research into a structure that can effectively resist the above-mentioned damage without reducing the performance of the fender, the present inventor has found that, in particular, the "Y" shown in Figure 1 d.
It has been found that by adopting a "shaped" cross-sectional structure, even if the impact-receiving part is made of a rubber material mixed with short fibrils, it is possible to effectively deal with the above-mentioned chipping damage without substantially reducing the performance of the fender itself.

した構造にある。 The present invention provides a rubber oblong cylindrical fender that exhibits excellent energy absorption performance against the compressive load applied when a ship berths, and also exhibits excellent durability against chipping damage. The gist of this is that the impact-receiving part of the "Y-shaped fender" is made of a rubber elastic material mixed with a large number of short and small fibers.

る。 To explain the above basic configuration in further detail, in the cross-sectional shape, there is a pair of support portions that are symmetrically inclined in a divergent shape, and a virtual center plane of both support portions that is integrally formed from one end of each of the support portions. one impact-receiving part that is formed to protrude upward along the support part, and integrally extends outward from the other end of each of the support parts in a direction orthogonal to the virtual center plane of both support parts. In an oblong cylindrical rubber fender, the width (W) of the impact receiving portion is approximately equal to the spacing (S) at the lower end of each of the supporting portions. , the impact receiving part further has a thickness (T) of T≒0.1 to a height (g) of the fender measured from the upper surface of the impact receiving part to the lower surface of the attachment part. It is characterized by being formed as if it were 0.3H and being made of a rubber elastic material mixed with a large number of short and small fibers.

形成されている。 FIG. 3 is a side view of a rubber fender according to an embodiment of the present invention, and FIG. 4 is a sectional view taken along line a-a in FIG. 3. As shown in FIG. 4, the fender 1 of this example includes a pair of support sections 3, 3 which are symmetrically inclined in a divergent shape, and both support sections integrally extending from the upper end of each support section 3. One impact receiving part 2 is formed to protrude upward along the virtual center plane (Y-Y) of the support part 3, and the virtual center plane of both support parts is integrally formed from the other end of each support part 3. It consists of a pair of mounting portions 4, 4 extending outward in a direction perpendicular to (Y-Y), and is formed in an oblong cylindrical shape as a whole, as shown in FIG.

is 250mm, and the distance between the lower ends of each support section 3, 3 (S)
is 162 mm, while the thickness of the impact receiving part 2 (T)
and width (W) are 60 mm and 162 mm, respectively. Further, the impact receiving portion 2 is made of a rubber elastic material mixed with a large number of short fine fibers 5.

Since it is formed so as to protrude so as to satisfy the relationship of 0.1 to 0.3H, and so that W≒S, the compressive force at the time of coming alongside is absorbed exclusively by the bending action of both support portions 3, 3. Moreover, as shown in FIG. 5, each of the supporting portions 3 that are being bent is prevented from contacting the side plate by the impact receiving portion 2, and can be deformed to a greater extent.
