The invention is designed to be installed on one or both of the shipboard and coastal facilities (eg, overhangs, wharf breaks, docks, floats or similar structures) to mitigate the impact of the ship on coastal installations. The formed elastic antiglare device.

It has long been used to mitigate the impact of ships on coastal facilities to protect both the sides of the ship and the coastal facilities of various resilient antiglare devices. Elastic antiglare devices generally considered to be used for this purpose are types that can exhibit an operation curve such as following the next step in turn during the elastic deformation period of the antiglare device.

(1) Initial load: During this period, the compression of the device and the increase in reaction force of the accompanying antiglare, which occurs when the ship is in contact with such antiglare, are greater than the increase in antiglare by such compression.

(2) Flexors: These flexors occur after the initial load, during which the increase in reaction force of the antiglare under compression is less than the rate of increase in the amount of deformation of the antiglare due to the fact that the antiglare is bent or curved. Decrease in value.

(3) Load final stage: The rate of increase of the reaction force of the antiglare device is again greater than the rate of increase of the deformation amount of the device due to the fact that the antiglare device is further compressed in contact with the shipboard.

The operation of the elastic antiglare device is evaluated in consideration of the amount of deformation of the device and the amount of energy absorbed by the device, that is, the energy absorbing power, of which deformation occurs following the impact from the ship against the device. Denotes the surface area of an area defined by the motion curve in a graph representing the motion curve, one of the coordinate sides of the curve representing the amount of deformation and one line drawn from the starting point of the load end machine on the motion curve Is crossing at right angles to one of them.

More specifically, the resilient antiglare device is considered to have a very good operating effect when the deformability of the device is large and at the same time a large surface area of the above described area is shown.

Some of the elastic antiglare devices exhibiting the above-described motion curves are given as examples.

U.S. Patent Nos. 945,456 (January 2, 1964), U.S. Patent Nos. 3,418,815 and 3,418,816 (Dec. 31, 1968), and U.S. Patent No. 3,820,495 (Patent Date June 28, 1974). The patent specification discloses a resilient antiglare device consisting of: a hollow rubber tube with a trapezoidal cross section with one attachment face, a cushioning face opposite the attachment face, and its attachment face and cushioning face. It consists of a pair of supporting parts between them, and the planar tube section perpendicular to the long side of the tube has a generally equilateral trapezoidal shape, the upper end of which forms a cushioning surface and the lower end of which forms an electrical attachment surface. Two sides of the same length form a support.

The British patent specification also states that the antiglare device of the above structure can achieve the maximum operating effect when the following requirements of the trapezoid forming the cross-sectional shape of the hollow rubber tube meet the following requirements.

A = H ~ 3H, B = 0.2H ~ 0.8H, t = 0.15H ~ 0.4H, and θ = 45 ° ~ 80 °

Of these, H is the height measured between the top and the bottom, A is the width of the bottom, B is the width of the top, t is the thickness of each support, and θ is the angle of each side to the bottom.

US Patent No. 3,418, 815 discloses an antiglare device of hollow, flexible tubing, such as that disclosed in the British Patent Specification, for optimal load distribution throughout the ship's side and also its resilient objects so that it has improved energy absorption. It has a hard plate attached to the buffer surface. The use of another rigid plate buried in the attachment surface of the hollow flexible tube is also disclosed therein.

U.S. Patent No. 3,418,816 discloses a composite antiglare device comprising a plurality of antiglare devices, each of which is substantially the same as that disclosed in U.S. Patent No. 3,418,815. Also, a resilient antiglare device having a structure having a substantially V-shaped cross section is well known, and a cross-sectional view thereof is as shown in FIG. 1 in the accompanying drawings.

Referring now to FIG. 1, this known V-shaped antiglare device consists of a pair of supports 1 and 2 which are elongated to the same width, each supporting part of which is one of the bridge portions 3. The bridge portion 3 is integrally connected at the edge and has a flat cushioning face 4 facing away from the side effects flanges 5 and 6, the flanges each having an associated support 1 and From different edges of (2), they protrude from each other in different directions and in parallel with the plane of the buffer surface (4).

This anti-glare device is integrally made of an elastic material such as rubber.

When applying a compressive force or an external pressure in the above-described structure and as shown in FIG. 1, for example, the swelling pressure is applied to the plane buffer 4 in a direction perpendicular to the plane of the buffer 4. At the same time, the anti-glare device is a flange (5) (6) that is firmly fixed using an anchor bolt, etc., and when it is installed in a coastal facility, the V-type anti-glare device supports the support (1) (2) to the bridge (3). The relative part of the antiglare connected integrally expands and contracts outward with the substantial intermediate part to the bridge part 3, respectively, and the bridge part 3 is supported by the support part 1 as indicated by a single dotted line X. Tends to extend outward in the space between and (2), and the relative part of the antiglare, in which the support parts (1) (2) are integrally connected to the bridge part (3), is connected to the bridge part (3). With the actual middle part In this way, the elastic portion is deformed and the bridge portion 3 has a tendency to extend outward in the space between the support portions 1 and 2, as indicated by a single dashed line X, and the support portions 1, 2 Is the result of the parts of the antiglare connected integrally to the bridging part 3 to their respective positions facing outward of the imaginary line Z, and the (Z) lines respectively correspond to the corresponding attachment flanges (5). ) Or (6) at right angles to the mounting surface and pass through point Q, with the supporting part 1 or 2 indicated by the double-dotted line Y, with the point Q to the side. When freely rotatable in the vertebrae of the vertebra, the supports 1, 2 bend outwardly in relation to each other with a relatively large amount of reaction forces resulting from the bow.

The motion curve of this antiglare shown in FIG. 1 is shown as (A) in the graph of FIG.

In the structure shown in FIG. 1, the outward expansion of the antiglare portion in which the support portions 1 and 2 are integrally connected to the bridge portion 3 and the protrusion of the substantially intermediate portion of the bridge portion 3 can be suppressed for as long as possible. If so, the time at which the flexion takes place in the support (1) (2) can be delayed for a significant period, which in turn leads to an improvement in the energy absorbency of the antiglare.

In addition, in the structure shown in FIG. 1, immediately after the supports (1) (2) start their bending, they are continuously contacted with the ship with the contact area of each support (1) (2) and the pressure on the ship is increased. The antiglare area to which the load is applied gradually increases.

The load acting area of the antiglare increases such that it extends out of the imaginary line Z passing through the point Q at right angles to the attachment flanges 5 and 6, with each support part 1 having its axis as the axis. When 2) can be diffracted in the deformation or elastic bending period of the antiglare occurring in the above-described manner, the supports 1, 2 bend completely outwards in relation to each other and at the same time a load acts on the antiglare. The direction is parallel to any of the imaginary lines Z through which each Z passes through the point Q.

This is the beginning of the third end stage of the aforementioned load, and the reaction force generated by the deformed or curved antiglare increases rapidly.

Therefore, during the bending period of the support (1) (2), the contact of the support (1) (2) to the shipboard is avoided and at the same time the ship's load is applied to the antiglare device diagonally with respect to the imaginary line (Z). In this case the bendability of the support 1, 2 can be suspended for a considerably extended period of time, which in turn leads to an improvement in the energy absorbency of the fragrance.

The antiglare device disclosed in U.S. Patent No. 3,829,495 can be considered as an improved version of the antiglare device shown in FIG. 1 in terms of energy absorption, and the structure of the antiglare device in the bridge portion of the U.S. patented antiglare device mentioned last. It is the same as seen in FIG. 1 except for the recessed groove and the recessed rib. In addition, the latter patent also discloses the use of rigid light guide plates each embedded in a corresponding flange.

According to the last mentioned U.S. patent, the rib antiglare slumped toward the length of the antiglare and bulged away from the inner surface of the bridge to the buffer surface in the space between the supports is severely with the support flexed outward in relation to each other. When refracted, the ribs are designed to rely on coastal facilities by supporting bridges with curved supports to further absorb impact energy.

On the other hand, a recessed groove that extends to the length of the antiglare and is confined to the buffer surface of the bridge on the opposite side of the recessed rib and thus divides the buffer surface into buffer zones, one in each of the recessed grooves, is designed to When the antiglare device is elastically deflected, the buffer zones in each of the recessed grooves move toward each other, while slipping occurs between the sides of the ship and each buffer bore so that the support is integral to the bridge. This avoids possible outward expansion of the part of the antiglare that is connected to it, i.e. as it occurs in the structure shown in FIG. 1 and in this way delays the timing at which each support starts to flex.

The antiglare structure disclosed in the last mentioned US patent can virtually represent an improved energy absorption based on the fact that the timing at which each support begins to flex is delayed by the presence of the recessed groove.

In practice, however, the friction coefficient between the cushioning zone and the shipboard of the antiglare device is not always fixed, but varies depending on the type of ship and the surface condition of the buffer zone, so that the antiglare device adds its load on the ship. Operation in the direction of closeness of the buffer zones to each other in each of the recessed grooves occurring when deflecting is not always stable and is easy to work at such a low coefficient of friction and at the same time it is delayed at a high position.

For example, the antiglare device disclosed in the last mentioned U.S. patent generally has an operating curve as shown by (B) in the graph of FIG. 2, but the antiglare device has a The operating curve as indicated by C) is shown, and the operating curve A is shown at the place where the friction agent is small. In other words, the antiglare device of the structure disclosed in the last mentioned US patent not only tends to change depending on the frictional agent generated between the buffer zone and the bow of the antiglare device, but also has relatively low energy absorption. Has disadvantages.

Incidentally, the present invention should provide an antiglare device capable of improved elastic deformation of the substantially Y-shaped cross section as its basic purpose, and the device may be compared with any of the above-described antiglare devices discussed above. It should be able to exhibit improved energy absorption.

Another main object of the present invention is to provide an anti-glare device capable of improved elastic deformation of the above kind which can satisfactorily and effectively alleviate the impact acting on it in any direction.

Another object of the present invention is to provide an antiglare device capable of improved elastic deformation of the above kind, which has a buffering capacity that varies depending on the magnitude of the impact applied to it.

Another object of the present invention is an improved elastic deformation of this kind that can be easily manufactured at any time without requiring any complicated process and without substantially requiring the use of specially designed manufacturing equipment for the production of antiglare devices of the invention. It is to provide an anti-glare device that can.

To this end, the present invention aims to be an anti-glare device that can be elastically deformed to be fitted to one or both of the impact portion and the water layer portion to alleviate the impact acting from the impact portion to the impact portion. The device generally consists of a generally rectangular cross section with a water column and a pair of relative supports which rely on the buffer so that they are separated from each other in the opposite direction of the water column.

The buffer part according to the present invention is composed of a single elongated buffer material having a rectangular cross section, and each support part leaning on the buffer material is bent in a width direction, and the support part is bent near the buffer material and each support part is bent toward a wide side. It consists of the leg part on one side and the heel part on the other side of the inflection point.

Each heel occupies a freely flanked side of each support, generally separated from the buffer, and has an attachment flange protruding outwards in a direction parallel thereto.

When each heel of the support is measured at right angles to the length of the antiglare and between the opposite sides of the insect repellent device, the gap is determined by the maximum internal distance or span (S) of the buffer (W). Is within the numerical range of greater than or equal to 0.75, and less than or equal to 1.08 times the width of such buffer.

That is 0.75W S 1.08 W

The value of the span S is the width W of the receiver at the shock absorber (see FIG. 4), and the distance of the span S when the total height H = 40 mm between the receiver surface and the attachment surface of the buffer is set. Several changes (for example, 0.75 W, 0.85 W, 1.00 W, 1.08 W, 1.15 W) are obtained by the compression test to obtain the maximum strain deflection and the reaction force and the absorption as shown in Table 1 below.

TABLE 1

The amount of compression refers to the ratio (h / H × 100) between the original height H and the height h during compression.

As shown in Table 1, the smaller the value of the span S, the higher the reaction force.

If this reaction force is too large, the ship's side may be damaged. On the contrary, even if the reaction force is too small, sufficient anti-glare function may not be achieved.

On the other hand, the maximum strain of refractive index decreases as the value of span S decreases.

However, the total evaluation of the fender performance is performed by the energy absorption amount calculated based on the reaction force and the deformation amount. In Table 1, the energy absorption amount is the highest with the span S = 1.00 W, and decreases even when the value of the span S becomes larger or smaller than this.

The energy absorption amount in the case of this span S = 1.00W was made into 100%, and the ratio with respect to this is shown on the right side of Table 1. In view of the shortcomings of this ratio and the case of over or under reaction, the present invention is limited to the range where the ratio is within about 80%, that is, the span S = 0.75w to 1.08w.

Preferably, the foot of each support portion preferably has a uniform thickness in the range of 0.2H to 0.4H, where it represents the total height of the antiglare device measured between the water repellent surface and the attachment surface of the buffer, and on the surface of the attachment There is a contact area of the attachment flange to the heel and the heel portion of the limb may have a uniform or non-uniform thickness.

Another buffer device of the present invention is composed of a pair of separate buffers each, each buffer has a support portion and has a buffer plate that firmly attached to the buffer to connect them.

The width W of this another shock absorber is measured between the opposite side of another buffer away from one of the buffers and the other opposite side of the other buffer.

In the two buffers of the present invention described above, the inclination angle of each foot of each of the supports is in the range of 55 ° to 80 ° with respect to the attachment surface, and the corresponding heel portion following the leg portion has an inner surface with respect to the attachment surface. It is desirable to design so that it lies at an angle in the range of 75 ° -90 ° and the outer surface is at an angle in the range of 55 ° -90 °.

In addition, the thickness of the shock absorber is in the range of 0.1H-0.35H, and the height of each heel portion is in the range of 0.15H-0.4H when measured from the attachment surface to the curve point, that is, the boundary point between the inner surface of the heel and the heel portion. desirable.

Before proceeding with the description of the present invention, it should be noted that similar parts are designated by the same reference numerals throughout FIG. 1.

First, see Figures 3 and 4. One of the ships and docking facilities (projecting docks, docks, breakwaters, docks, floats, or similar structures, etc.) for the purpose of mitigating the impact or impact energy acting on the docking facilities from the ships. Or the antiglare structure, which can be elastically deformed in particular for use on both sides, is made of a resilient material such as rubber and constitutes a elongated body of monolithic structure with a cross-sectional shape like "Y" shape. have.

The antiglare body includes a buffer body 10 having a generally rectangular cross section, the buffer body comprising a pair of side surfaces 12 and at right angles to the outer surface and the outer surface of the water layer portion 11 forming a rot. 13) and there is a pair of supports 14 and 15 which protrude symmetrically on the inner surface of the buffer 10 so that they are separated from each other outward as they gradually fall away from the buffer 10.

The buffer 10 and the symmetrical supports 14, 15 are generally triangular in cross-section with the surface of the bot, whether the bot is an eyepiece or a ship when the antiglare device of the present invention is attached to the bot. To form an elongated hollow space.

As shown in FIG. 4, each support 14, 15 is bent to a wider side and thus consists of a foot 16, 17, which is close to the buffer 10 and each support 14. And (15) lie on one side of the bend and the heel 18, 19 lies on the other side of the bend.

Each of the heel portions 18, 19 separates the flanges 20, 21 which are spaced apart from the buffer 10 and which extend outwardly in the opposite direction of the void space and in parallel with the plane of the receiver 11. The open face portions of the supporting portions 14 and 15 are generally occupied.

When the supports 14, 15 protrude from the buffer 10 so as to be apart from each other as described above, the heel 18, 19 of each of the supports 14, 15 meets the following equation from each other. It is placed at intervals of the maximum span S.

0.75 W S 1.08 W

Where W represents the width of the buffer 10 measured between the sides 12 and 13, respectively.

The buffer body 10 of the antiglare device structured according to the configuration shown in FIGS. 3 and 4 is preferably in the range of 0.1H-0.3H, more preferably in the range of 0.2H-0.25H (where H is the water repellent 11 Is the total height (H) of the antiglare device measured between the contact surface of the mounting flange 20 and the contact surface of the mounting flanges 20 and 21, as shown in FIG. Due to the fact that the bending motion impacts the antiglare body through the receiver 11, the timing at which it occurs at the supports 14 and 15 can be delayed, so that the antiglare body is considerably You can keep his hardship for a period of time.

In addition, after the support parts 14 and 15 have been subjected to the bending motion once by the action of the impact applied to the antiglare, when the outer surfaces of the support parts 14 and 15 are completely bent, they are impact products, for example, The timing of contacting the shipboard may be delayed and delayed so that the antiglare supports a relatively large amount of deformation of the supports 14, 15.

When the thickness T of the shock absorber 10 is less than the lowest point, in the case of the previously designed antiglare device having the structure shown in FIG. 1, the supports are increased to cause a decrease in the energy absorption capacity of the antiglare device itself. There is a possibility of bending immediately upon impact on the water surface with the surface area of the water surface.

On the other hand, if the thickness T of the shock absorber 10 is larger than the upper limit and it can lead to a decrease in the width of each support portion 14 and 15 with respect to the constant height of the antiglare device, the antiglare structure will be impacted. When acting on it through this receiver 11, it tends to return to its original shape and generates a considerable amount of reaction force, which causes the antiglare structure to lose its ability to support the relatively large deformation of the support. .

The fact that each of the supports 14 and 15 bends to an extent at the boundary between the corresponding legs 16, 17 and the heel 18, 19 is that the supports 14, 15 are entangled. According to the compression of the shock absorber 10 in the impact action against 11), the fifth (a) to the fifth (c) can be bent sequentially.

In more detail, when the side plate of a ship approaching the eyepiece facility is contacted with respect to FIG. 5, it is assumed that the side plate of the ship contacts the receiver 11 of the antiglare structure depending on the eyepiece structure, the buffer body 14 (15). With the first compression inward and attempt to bend outward in relation to each other around the perimeter between the legs 16, 17 and heel 18, 19, which is the fifth (a) and fifth (b) It can be easily understood in the comparison of the states as seen in the figure.

It should be noted that the states shown in FIGS. 5 (a) and 5 (b), respectively, represent the anti-glare object of the present invention which is 20% and 30% compressed compared to the original form.

Like the antiglare device shown in FIG. 1, unless each support is bent as described in the present invention, the support can be bent irregularly and at different bending points without a substantial cushioning effect that continues for a long time. There is a possibility.

The respective support portions 14 and 15 being bent, i.e., the support portions 14 and 15 corresponding leg portions 16, 17 or heel portions 18 and 19, which are integrally connected to each other at a constant angle. ) Facilitates the bending operation of each support 14 and 15 of the Korean food according to the compression of the buffer 10, and whether the support 14 or 15 follows the bending operation of the support 14 or 15. Prevents sudden and rapid reduction of unknown rigidity and thereby delays the time at which the curved supports 14, 15 may eventually come into contact with the side plates of the ship and, together with the pontoon 11, Such contact of the bent supports 14, 15 to the side occurs when the antiglare of the present invention is compressed or refracted, for example, about 60% with respect to the circle.

On the antiglare structure shown in FIGS. 3 and 4, the motion curve is indicated by (D) in the graph of FIG.

It should be noted that, as shown in FIG. 4, where the supporting portions 14 and 15 are bent at the attachment surface, that is, their respective legs 16 and 17 or the heel portions 18 and ( The height h measured to the boundary line between 19) is preferably in the range of 0.15H-0.4H, more preferably in the range of 0.175H-0.275H, where H represents the total height of the antiglare as described above. .

It should also be noted that the leg portions 16 and 17 of the outer portions 18a and 19a of each of the heel portions 18 and 19 of the supports 14 and 15, respectively, are mated. The outer surface 16a, 17a, and the same surface, which will be understood in the description below.

Even if the outer surfaces 18a and 19a of the heel portions 18 and 19 have the same surface as the outer surfaces 16a and 17a of the leg portions 16 and 17, respectively, the supporting portion 14 And the bending motion of (15) is performed on each leg portion 16 to which the inner surfaces 18b and 19b of the heel portions 18 and 19 are connected to the inner surfaces 18b and 19b. As long as it is arranged to intersect the planes of the inner surfaces 16b and 17b of (17), it can occur without difficulty.

However, if the planes of the respective outer surfaces 18a and 19a are arranged to intersect the planes of the outer surfaces 16a and 17a of the leg portions 16 and 17 as shown, the support 14 and (15) This bending operation can be made easily.

The support portions 14 and 15 connected to the buffer body 10 protrude from the buffer body 10 so as to be separated from each other as they gradually move away from the buffer body 10, and the support portions 14 and 15 thereof. The flared angle of is such that the outer surface 16a and 17a or any of the inner surfaces 16b and 17b of any of the legs 16 and 17 forms an θ1 angle in the range of 55 ° -80 °, preferably It is selected to form a range of 65 ° -75 ° and this angle is relative to the attachment surface when any of the leg portions 16 and 17 has a uniform thickness T in the range 0.2H-0.4H and also the heel The inner surfaces 18b and 19b or the outer surfaces 18a and 19a of any of the sections 18 and 19 are configured to form angles θ2 and θ3, respectively, and θ2 is 75 ° -90 with respect to the attachment surface. It is in the range of ° and θ3 is in the range of 55 ° to 95 ° with respect to the attachment surface.

When the thickness of any of the heel portions 18 and 19 is equal to or greater than the thickness t of any of the leg portions 16 and 17, the leg portions 16 and 17 respectively. The thickness t should be selected within the above range because it is the amount of deformation of the supports 14 and 15 during the impact or bending action on the supports 14 and 15 and the receiver 11. This affects when to start their bend.

In any case, the antiglare structure of the present invention is 0.75W. S Satisfying the condition of 1.08 W causes the buffer body 10 to be fully compressed at the beginning of the impact action on the antiglare, that is, the curved supports 14 and 15 contact the side plate of the ship. It is critical that it be placed inside the imaginary surface (Z) passing through each point (Q) at right angles to the attachment surface for the duration of the work up to this point.

This is necessary to avoid the possibility of generating an excessive amount of reaction force that may cause the ship to fall away from the eyepiece and away from the dock's side plate, which is far from allowing the ship to approach the eyepiece. Large amounts are also needed to absorb shock or impact energy.

It should be noted that the maximum point 0.75W under the condition of the total length S relative to the width W indicates the possibility of the impact acting diagonally on the receiver 11 as indicated by arrow F ₂ of FIG. 4. Consideration is possible when one heel component (not shown) is formed in each heel portion 18 or 19 so as to project in the opposite direction to the elongated direction of the attachment flange 20 or 21. It is.

The lowest point where each heel component shown is not provided in the heel portions 18 and 19 should be the same as the width W of the buffer 10.

In the structure fully described with reference to FIGS. 3 and 4, rigid reinforcing plates (such as metal or wood boards or textile fabrics) are applied to the respective attachment flanges 20 and 21 to the heel portions 18 and 19. It is possible to embed it into the inside, thereby making it possible to firmly fix the anti-glare of the present invention to the insect body.

In the same way a similar reinforcement plate can be buried in the buffer 10 if desired, and the water receiving surface 11 of the buffer 10 can be made of a material having high abrasion resistance and low coefficient of friction (e.g. Film may be coated with a layer of ethylene).

Although the antiglare shown and described in connection with FIGS. 3 and 4 is a monolithic structure made of an elastic material, the antiglare may also be composed of separate antiglare bodies each having a monolithic structure made of an elastic material.

And this is described next with reference to FIGS. 6 and 7.

Referring to FIGS. 6 and 7, the anti-glare structure is composed of a pair of anti-glare bodies spaced apart from each other, and the angular anti-glare body includes a buffer body 10a, 10b, a support part 14, 15, and an attachment flange 20. (21) is the same as seen in FIG. 3 and FIG.

In the configuration shown in Figs. 6 and 7, each of the buffers 10a and 10b has a rectangular cross section with a pair of upper sides 12a and 12b or 13a and 13b and An integrated shoulder portion 22 or 23 is included, and the buffer body 10a or 10b is connected to the leg plate 24 through these.

The leg plate 24 penetrates through the shoulders 22 and 23 and is fixed to the leg plate 24 using the anchor bolt 25 held by the leg plate 24. ) Connect the starboards. The shoulders 22 and 23 are shown to have angular reinforcement plates 26 and 27 embedded therein for the purpose of providing rigidity to the shoulders 22 and 23.

However, the use of these reinforcing plates 26 and 27 is not critical. Preferably, the leg plate 24 is made of a hard material, such as wood or metal, and at least one surface of the leg plate 24 opposite the shoulders 22, 23 is placed on the resilient pad or the film. It is supposed to be coated.

In use, the anti-glare device is connected to the main body together with the leg plate 24 and mounted on the water repellent body so that the maximum length S between the supports 14 and 15 of the heel portions 18 and 19 is 0.75D. S Within the range of 1.08D, where (D) represents the distance between the outer axial surface 12b of the buffer 10a and the outer side surface 13a of the buffer 10b.

However, as in the case of the above described configurations of FIGS. 3 and 4, the lowest point should be equal to the distance D if neither heel component of each of the heel portions 18 and 19 is provided.

In the sequence of operation of the antiglare, that is, the compression, which is another configuration of the present invention as shown in FIGS. 8 (a) -8 (d), It can be easily seen that it works in the same way as the antiglare according to the electronic configuration shown in the figure.

Each of the attachment flanges 20 and 21 has been shown to have a reinforcement plate 29 or 30 embedded therein to provide rigidity for the attachment flanges 20 and 21.
