Description

Application of Article 30, Paragraph 2 of the Patent Act Sold to Mitsubishi Heavy Industries Transportation and Construction Engineering Co., Ltd. on January 24, 2020 and April 21, 2020.

The present invention relates to a canopy forming member, a canopy using the same, and a method for manufacturing a canopy.

At airports, boarding bridges are used to transport passengers between planes and terminal buildings. A canopy that covers the tip of the boarding bridge like a hood is provided at the tip of the boarding bridge on the airplane side (for example, Patent Document 1). This prevents wind and rain from entering the boarding bridge.

As described in FIG. 2 of Patent Document 1, the canopy (closure 11) includes a ceiling surface and left and right side surfaces, and each of these surfaces is formed into a bellows structure consisting of a series of mountain folds and valley folds. Furthermore, as shown in FIG. 2 of Patent Document 1, the canopy needs to curve along the fuselage of the airplane, so it is made of a flexible material. The flexible material is, for example, a sheet of Tetoron (polyester) base fabric coated with soft PVC on both sides to be flameproofed.

Utility Model Publication No. 3-28997

However, the canopy as described in Patent Document 1 has a problem in that during rainy weather, rainwater accumulates in the valley folds of the bellows structure on the ceiling surface, resulting in poor drainage. In particular, since the canopy is made of a flexible material, when there is a lot of rain, the valley folds on the top surface form a pocket structure due to the weight of the rainwater, where rainwater accumulates and worsens drainage. There was a problem.

In view of the above problems, the present invention aims to provide a canopy with good drainage.

In the following description, when referring to directions such as up, down, left, and right, the directions are meant to be up, down, left, and right when viewed from the front in the drawing.

<Overview of canopy>
First, an overview of the canopy 1 will be explained. FIG. 1 shows a canopy 1 attached to the tip of a boarding bridge (not shown) on the airplane (not shown) side, as seen from the airplane side. As shown in FIG. 1, the canopy 1 covers the floor FL of the passageway of the boarding bridge like a hood.

As shown in FIG. 2, the ceiling surface of this canopy 1 has a bellows structure 2. Although not shown, both sides of the canopy 1 also have a bellows structure.

This bellows structure 2 expands and contracts in the front-rear direction (direction perpendicular to the paper plane of FIG. 1). However, as shown in FIG. 2, the length that this bellows structure 2 can extend is limited by a restriction belt B2. Note that, as shown in FIG. 1, the canopy 1 includes a total of five restriction belts B1 to B5, including the restriction belt B2.

By the way, as shown in FIG. 1, the ceiling surface of this canopy 1 (the valley line 4a1 of the bellows structure 2) is such that the height of the part located on the center line O of the canopy 1 shown in FIG. It is formed to be higher by a height H than both left and right end portions of. As a result, an inclined portion is formed on the ceiling surface of the canopy 1, so that rainwater falling on the canopy 1 easily flows down from the ceiling surface.

The canopy 1 as described above is mainly composed of a cushion member 13, a connecting member 14, and a forming member 3, as shown in FIG. Each component will be explained below.

<Description of cushion member>
As shown in FIG. 1, the cushion member 13 includes a horizontal member 13a and a pair of left and right vertical members 13b attached to both left and right ends of the horizontal member 13a.

Both the horizontal member 13a and the vertical member 13b have an elongated square column shape. These horizontal members 13a and vertical members 13b are made by attaching a square column-shaped rubber sponge to a core material made of a metal material such as a high-tensile steel plate, and covering the core material with a flexible material. The flexible material is, for example, a sheet of Tetoron (polyester) base fabric coated with soft PVC on both sides to be flameproofed. Furthermore, as shown in FIG. 1, two thin silicone sponges 11a having the same length as the width in the longitudinal direction (horizontal direction in FIG. 1) of the cross member 13a are placed on the side surface of the cross member 13a on the airplane side. are installed in parallel. On the other hand, a thin silicone sponge 11b having a length of about one-fifth of the width in the longitudinal direction (vertical direction in FIG. 1) of the vertical members 13b is placed on the upper part of the side surface of the pair of left and right vertical members 13b on the airplane side. They are installed one by one.

As shown in FIG. 1, a pair of left and right devices 16a for connecting the canopy 1 and the boarding bridge are provided on the back surface (side surface opposite to the airplane side) around the lower end portion 13b1 of the vertical member 13b. ing. However, since the pair of left and right instruments 16a have a conventionally well-known structure, a detailed explanation thereof will be omitted.

<Description of connecting members>
As shown in FIG. 1, the connecting member 14 is provided so as to cover the periphery of the cushion member 13. Further, as shown in FIG. 1, the connecting member 14 includes a horizontal member 14a and a pair of left and right vertical members 14b attached to both left and right ends of the horizontal member 14a.

This connecting member 14 will be explained in more detail using FIG. 3. As shown in FIG. 3, the connecting member 14 is arranged on the other side of the cushion member 13 (the rear side in FIG. 3).

Then, an end side 14a1 of the cross member 14a of the connecting member 14 shown in FIG. 3 on the cushion member 13 side (front side in FIG. 3) is connected to the cross member 13a of the cushion member 13 by stitching or the like. The cross member 14a of the connecting member 14 connected to the cushion member 13 in this manner forms a slope that descends toward the cushion member 13 (front side in FIG. 3), as shown in FIGS. 2 and 3.

Similarly, the vertical member 14b of the connecting member 14 shown in FIG. 3 is also connected to the vertical member 13b of the cushion member 13. Although not shown, the vertical member 14b of the connecting member 14 forms a slope that slopes from the outside to the inside of the canopy 1.

<Description of forming members>
Hereinafter, regarding the forming member 3, a description of the expanded state of the forming member 3, a description of a process for forming the forming member 3 into the shape shown in FIG. 3, and a description of the forming member 3 shown in FIG. The explanation will be divided into two parts: a method for forming the bellows structure 2 as shown;

<Description of the expanded state of the forming member>
FIG. 4(a) shows a state in which the forming member 3 (see FIG. 3) is developed. As shown in FIG. 4(a), the forming member 3 includes a forming member main body 4, a right side forming portion 5a, and a left side forming portion 5b. Note that the forming member 3 is made of a flexible material. The flexible material is, for example, a sheet of Tetoron (polyester) base fabric coated with soft PVC on both sides to be flameproofed.

The forming member main body 4 forms the bellows structure 2 of the ceiling surface of the canopy 1 (see FIG. 2). Therefore, the length of the forming member main body 4 in the longitudinal direction D1 (the left-right direction in FIG. 4) is approximately equal to the width of the ceiling surface of the canopy 1 (the length of the ceiling surface of the canopy 1 in the left-right direction in FIG. 1). As shown in FIG. 4(a), this forming member main body 4 has a width L in a direction D2 (vertical direction in FIG. 4) perpendicular to the longitudinal direction D1 (horizontal direction in FIG. 4) formed from a corner crease C. It is formed in a tapered shape toward the center line P of the member 3.

On the other hand, the right side forming part 5a and the left side forming part 5b form a bellows structure (not shown) on both sides of the canopy 1 shown in FIG. Therefore, the length of the right side forming part 5a and the left side forming part 5b in the longitudinal direction D1 (horizontal direction in FIG. 4) is the height of the side surface of the canopy 1 (in the vertical direction of the side surface of the canopy 1 in FIG. 1). approximately equal to the length).

Note that the right side forming part 5a and the left side forming part 5b may be provided with a notch 5b1 and a notch 5b2 (see FIG. 4(b)), which will be described later.

<Explanation of processing of forming members>
In manufacturing the canopy 1, the forming member 3 is processed to have a shape as shown in FIG. 3. This process will be explained using FIGS. 5(a) and 5(b).

The right side forming part 5a shown in FIG. 5(a) is the right side forming part 5a shown in FIG. 4(a) in a state where the forming member 3 is bent along the corner crease C as shown by the arrow Y1. . A pinch stitch is applied to the right side forming portion 5a along the corner crease C. That is, the forming member 3 is folded along the corner crease C and the loop is sewn together. This gives the forming member 3 a habit so that it can maintain the bent state at the corner crease C (see FIG. 5(b)).

Similarly, a chevron-shaped pinch stitch is performed from one end Ca of the corner fold line C shown in FIG. 5(a) to the other end Cb along the folded fold line C2. As a result, the forming member 3 is shaped so that it can maintain the bent state at the fold line C2 (see FIG. 5(b)).

Next, the corner crease C is bent into a V shape (see FIG. 5(b)) so that a valley line 4a1 (see FIG. 5(b)) is formed at the position indicated by the two-dot chain line in FIG. 5(a). At the same time, it is folded back along the folded fold C2 as shown by the arrow Y2 so that the apex of the chevron-shaped folded fold C2 touches the valley line 4a1 from below (see FIG. 5(b)).

By doing the above, it is possible to obtain a forming member 3 having a shape as shown in FIG. 5(b).

The above process is also performed on the left side surface forming portion 5b. Thereby, the forming member 3 having the shape shown in FIG. 3 can be obtained. Although not shown, the forming member 3 processed as described above also has a downward U-shape with an open bottom, similar to the cushion member 13 and the connecting member 14.

<Description of formation of bellows structure using forming members>
A method of forming the bellows structure 2 (see FIG. 2) using the forming member 3 treated as described above will be described.

First, the forming member 3 shown in FIG. 3 is sewn to the connecting member 14. Specifically, among the longitudinal direction (left-right direction in FIG. 3) end sides 4b1 and 4b2 of the forming member main body 4 of the forming member 3 shown in FIG. 3, the near side (front side in FIG. 3) 4b1 is sewn to the end side 14a2 on the other side (back side in FIG. 3) of the connecting member 14 shown in FIG. Similarly, the right side forming portion 5a and the left side forming portion 5b of the forming member 3 are also sewn to the left and right vertical members 14b of the connecting member 14.

Here, when sewing together the forming member 3 and the connecting member 14, as shown in FIG. I'll leave it there.

The rope fixing portion brackets R1 and R2 are for holding an aggregate 15 (see FIG. 6(b)), which will be described later, using a rope. A rope hole h for inserting a rope is formed at the tip of the rope fixing part brackets R1 and R2. Further, the rope fixing portion brackets R1 and R2 are made of the same flexible material as the forming member 3. A total of 14 sets (28 pieces in total) of such rope fixing part brackets R1 and R2, including 4 sets (8 pieces) of rope fixing part brackets R1 and R2 shown in FIG. 3, are arranged at predetermined intervals, The proximal sides are sewn together between the forming member 3 and the connecting member 14.

Next, a plurality of forming members 3 are further sewn to the other side (back side in FIG. 3) of the forming member 3 shown in FIG. For example, to form the bellows structure 2 having eight peaks 4a2 (see FIG. 2), a total of seven forming members 3, including the connecting member 14 shown in FIG. 3 and the forming member 3 sewn together, are sewn together. becomes.

Specifically, first, the forming member 3 (first forming member 3) shown in FIG. The eye forming member 3) is sewn together. When sewing together, the adjacent edges of these forming members 3, that is, the edge 4b2 on the far side (back side in FIG. 3) of the first forming member 3, and the near side (on the near side of the second forming member 3) The front side in FIG. 3) is sewn together with the edge 4b1. Similarly, adjacent sides of the right side forming part 5a and the left side forming part 5b shown in FIG. 3 are sewn together.

At this time, 14 sets of rope fixing brackets R1 and R2 (see FIG. 3) are also inserted between the first forming member 3 and the second forming member 3 at predetermined intervals, and the proximal end is sewn together.

In this way, by sewing together the connecting member 14 and the plurality of forming members 3, the bellows structure 2 as shown in FIG. 2 is formed. Note that although only the peak portion 4a2 of the ceiling portion is shown in FIG. 2, the peak portion 4a2 is formed over the ceiling and the left and right side surfaces. When the bellows structure 2 is viewed from inside, a plurality of pairs of rope fixing portion brackets R1 and R2 are suspended from the ceiling and the peak portions 4a2 on the left and right side surfaces (not shown).

Note that, as shown in FIG. 6(a), the valley line 4a1 is not inclined at this point. Therefore, from inside the bellows structure 2, as shown in FIG. 6(b), the aggregate 15 is inserted into each peak portion 4a2 (see FIG. 2). This aggregate 15 has a core material formed of a metal material such as a high-tensile steel plate, and the core material is covered with a flexible material similar to the forming member 3. As shown in FIG. 6(b), it has a downward U-shape with an open bottom, similar to the bellows structure 2, the cushion member 13, and the connecting member 14.

Such an aggregate 15 is inserted from the inside of the bellows structure 2 between each pair of a plurality of rope fixing portion brackets R1 and R2 hanging from a peak portion 4a2 formed over the ceiling and left and right side surfaces. For example, to form the bellows structure 2 having eight peaks 4a2 (see FIG. 2), a total of eight aggregates 15, one aggregate 15, must be inserted into each of the peaks 4a2 (see FIG. 2). Become.

Then, one end of a rope (not shown) is fixed to one rope fixing part bracket R1 of each pair, and the other end is passed under the aggregate 15 and fixed to the other rope fixing part bracket R2. In this way, one aggregate 15 is fixed to the peak portion 4a2 of the bellows structure 2 by 14 sets of rope fixing brackets R1 and R2 (see FIG. 3). As a result, as shown in FIG. 6(b), the peak portion 4a2 is pulled upward by the aggregate 15, and the peak portion 4a2 becomes a horizontal straight line. Along with this, the valley line 4a1 is also pulled upward, as shown in FIG. 6(b).

Here, as shown in FIG. 4(a), the forming member main body 4 is formed in a tapered shape toward the center line P side. Therefore, as shown in FIG. 6(b), the portion located at the center line O of the valley line 4a1 is pulled the highest. Thus, as shown in FIG. 1, the height of the valley line 4a1 of the ceiling surface of the canopy 1 at the point located on the center line O of the canopy 1 shown in FIG. It will be formed to be higher by the height H. That is, an inclined portion is formed on the ceiling surface of the canopy 1.

As explained above, conventional canopies have a problem in that rainwater accumulates in the valley folds of the bellows structure on the ceiling surface, resulting in poor drainage. However, according to the present embodiment, since the ceiling surface can be formed with a V-shaped slope, it is possible to provide a canopy from which rainwater easily falls from the ceiling.

Moreover, if the forming member 3 shown in this embodiment is configured, there is no need to complicate the shape of the aggregate or use another metal material in order to slope the ceiling surface. Therefore, even if the canopy curves along the fuselage of the airplane, the problem of damage due to localized stress is unlikely to occur.

As described above, according to the present embodiment, a canopy with good drainage can be provided.

<Explanation of the cutout>
By the way, in the above explanation, the case where the manufacturing is performed using the forming member 3 as shown in FIG. 4(a) has been explained, but since the forming member 3A as shown in FIG. I will explain about it.

Among the configurations of the forming member 3A shown in FIG. 4(b), the same components as those of the forming member 3 shown in FIG. 4(a) are given the same reference numerals, and the description thereof will be omitted. The forming member 3A shown in FIG. 4B is different from the forming member 3 shown in FIG. This is the point where 5b2 is formed. More specifically, in the center of the left side forming portion 5b shown in FIG. A notch portion 5b1 is formed along the left-right direction). and. In the center of the right side forming part 5a shown in FIG. 4(b) (direction D2 (vertical direction in FIG. 4) perpendicular to the longitudinal direction D1 (horizontal direction in FIG. 4)), the longitudinal direction D1 (horizontal direction in FIG. 4) The point is that a notch portion 5b2 is formed along.

In order to form the shape shown in FIG. 3 using the forming member 3A having such a shape, first, as shown in FIG. Both sides 5b31 and 5b32 of the cutout portions 5b1 and 5b2 are sewn together. After that, by performing the same process as for the forming member 3 shown in FIG. 4(a), it is possible to obtain the forming member 3 having the shape as shown in FIG. 5(b).

However, the thickness W of the right side forming part 5a shown in FIG. 5(b) is thinner when using the forming member 3A shown in FIG. 4(b) than when using the forming member 3 shown in FIG. 4(a). Become something. This point will be explained in more detail using FIG. When the forming member 3 shown in FIG. 4(a) is used, the thickness of the bellows structure 2 (the distance between the valley line protruding toward the floor FL side of the passageway and the ridge line protruding outward) is equal to the thickness W1 shown in FIG. have On the other hand, when the forming member 3A shown in FIG. 4(b) is used, the thickness of the bellows structure 2 becomes thinner by the notch portion 5b2, and becomes the thickness W2 shown in FIG. 1.

Therefore, if the canopy 1 is manufactured using the forming member 3A, the possibility that the bellows structures 2 on both the left and right sides of the canopy 1 will hit passengers, luggage, etc. moving inside the canopy 1 can be reduced.

In addition, in order to increase the angle of inclination of the curved shape formed on the ceiling surface of the canopy 1, the width L of the right side forming part 5a and left side forming part 5b shown in FIG. 4(a) is made larger. By increasing the length, the taper angle can be increased. However, in this case, the thickness W1 shown in FIG. 1 becomes larger. However, even in such a case, the thickness W1 can be suppressed by forming the cutout portions 5b1 and 5b2 as shown in FIG. 4(b).

<Explanation of modification example>
Note that the forming member and canopy shown in this embodiment are merely examples, and various modifications and changes can be made within the scope of the gist of the present invention as set forth in the claims. For example, in this embodiment, the forming member 3 in which the forming member main body 4, the right side forming part 5a, and the left side forming part 5b are integrally formed is used, but the present invention is not limited to this. A forming member 3 in which the surface forming portion 5a and the left side forming portion 5b are separate may be used.

Further, the width L of the forming member 3 is tapered from the corner crease C to the center line P (see FIG. 4(a)), but the forming range is not limited to this. For example, it may be formed toward the center line P from both left and right ends or from a position closer to the center line P than the corner crease C.

Further, in the present embodiment, an example is shown in which the ceiling surface of the canopy 1 is formed using the forming member 3, but the height of the portion located on the center line O of the canopy 1 shown in FIG. 1 is not limited thereto. However, any forming member may be used as long as it is formed to be higher than the left and right end portions of the ceiling surface of the canopy 1 by a height H. However, it is preferable to use the forming member 3. There is no need to complicate the shape of the aggregate or use a separate metal material to create a sloped ceiling surface, and even if the canopy curves along the fuselage of the airplane, local stresses are not generated. This is because the problem of damage is less likely to occur.

Further, in the present embodiment, an example in which the forming member 3 has a left-right symmetrical shape is shown, but the shape is not limited thereto, and the shape may be left-right asymmetrical.
