Description

[Technical Field]

[0001] The present invention relates to a cover unit that serves as a member for covering a switchboard provided inside a passenger car in a railway vehicle. [Background technology]

[0002] Railway passenger cars are equipped with equipment such as switchboards and trash cans. It is not desirable to expose these inside the car from the standpoints of safety, appearance, and vehicle design. Therefore, a cover unit that covers the equipment is installed on the access platform (deck) installed in the passenger car.

[0003] Patent Document 1 discloses a multipurpose box that can store a switchboard and trash cans and is installed on the entrance and exit platform (deck) of a railway vehicle. This multipurpose box is formed into a box shape by fastening the edges of panels with screws to frames erected at the four corners (front, rear, left, and right). The ceiling is also closed with panels. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-171519 Summary of the Invention [Problem to be solved by the invention]

[0005] The multipurpose box in Patent Document 1 has rail members (horizontal frames) fixed to the vertical frame by welding. Also, frame members (pillars) are erected at the four corners (front, back, left, right). Therefore, there are issues such as distortion due to welding, and the four frame members are difficult to adjust in height, making it difficult to install on the floor (prone to rattle). [Means for solving the problem]

[0006] The present invention has been conceived in view of the above problems, A cover unit covering a distribution board installed in the end body of a passenger car of a railway vehicle, a first vertical frame fixed to the side structure; a support pillar arranged at a position a predetermined distance away from the first vertical framework toward the vehicle interior side; A second vertical frame fixed to the end structure; a floor surface fixing bracket for fixing the first vertical aggregate and the second vertical aggregate to a floor surface; At least two first horizontal aggregates extending between the first vertical aggregates and the support columns; At least two second horizontal aggregates extending between the second vertical aggregates and the support columns; an oblique connecting bracket fixed to the support column to connect the first horizontal frame and the second horizontal frame; a first panel disposed between the first vertical frame and the support column; a second panel disposed between the second vertical frame and the support column; The first panel or the second panel is characterized in that a hinged door is provided on the first panel or the second panel. [Effects of the Invention]

[0007] In the cross frame unit according to the present invention, the first vertical frame and the second vertical frame are fixed to the side structure and the end structure, and the support columns are supported by horizontal frame members fixed to the first vertical frame and the second vertical frame, and are not fixed to the floor surface. Therefore, there are almost no welds, so distortion is unlikely to occur at the connection points between the frames. Furthermore, because the support columns are not fixed to the floor surface, even if distortion occurs at the connection points between the frames, the distortion can be absorbed by the support columns, making the distortion less noticeable. Another advantage is that assembly is easy.

[0008] In addition, by using a composite panel material made of a top plate, core material, and back plate, it is possible to rivet the joining bracket on the back side, and fixing screws etc. are not visible on the front side, which is also ideal from a design perspective.

DETAILED DESCRIPTION OF THE INVENTION

[0010] The following describes a kinematic unit according to the present invention with reference to the drawings. Note that the following description exemplifies one embodiment of the present invention, and the present invention is not limited to the following description. The following description can be modified within the scope of the present invention.

[0011] The cover unit 1 according to the present invention is a cover that covers equipment such as a switchboard installed on the end body of a passenger car of a railway vehicle. The equipment may also include a fire extinguisher or a trash can. The cover unit 1 conceals the equipment from passengers as part of the vehicle design.

[0012] FIG. 1 is a perspective view of the cover unit 1 as seen from inside a passenger car of a railway vehicle. FIG. 1(a) shows the case when the first main door 14a is closed, and FIG. 1(b) shows the case when the first main door 14a is open. The cover unit 1 is provided on the left and right sides of an aisle door 104 provided on an end body structure 102. It may be provided on only one side of the aisle door 104. The cover unit 1 has a first wall surface 10 that is a wall parallel to the end body structure 102, and a second wall surface 12 that is parallel to the side body structure 100. The length of the first wall surface 10 from the side body structure 100 is called the width 10w of the first wall surface, and the length from the end body structure 102 is called the width 12w of the second wall surface.

[0013] Furthermore, when describing each component hereinafter, when distinguishing between the components that constitute the first wall surface 10 and the components that constitute the second wall surface 12, the component that constitutes the first wall surface 10 will be labeled "first" and the component that constitutes the second wall surface 12 will be labeled "second."

[0014] The cross section unit 1 has a space surrounded by the first wall surface 10, the second wall surface 12, the side structure 100, the end structure 102, the ceiling structure 110 (which may be the ceiling surface of the passenger car), and the floor structure 112 (which may be the floor surface of the passenger car). This space is called the inside 1in of the cross section unit, and the inside of the passenger car is called the outside 1out of the cross section unit. The first wall surface 10 and the second wall surface 12 are fixed to at least the side structure 100, the end structure 102, and the floor structure 112, and these may be fixed directly or via connecting brackets (indirectly). Inside 1in of the cross section unit, equipment equipment EB such as a distribution board is arranged.

[0015] It is also desirable that one or more opening / closing doors 14 be provided on the first wall surface 10 or the second wall surface 12. The housing unit 1 is made up of the first wall surface 10 and the second wall surface 12.

[0016] <Aggregate: Vertical aggregate> Fig. 2 is a perspective view showing only the cross section unit 1. Fig. 2(a) is a view seen from the outside 1out of the cross section unit, and Fig. 2(b) is a view seen from the inside 1in of the cross section unit.

[0017] 2(b), the cross section unit 1 has first vertical aggregates 20, support columns 22, and second vertical aggregates 24 as vertical aggregates (referred to as "vertical aggregates").

[0018] More specifically, the support pillar 22 is positioned at a point inside the vehicle from the side structure 100 by the width 10w of the first wall surface, and at a point away from the end structure 102 by the width of the second wall surface 12w.

[0019] Additionally, auxiliary vertical frames 26 may be provided between the first vertical frame 20 and the support pillar 22, or between the support pillar 22 and the second vertical frame 24. The auxiliary vertical frames 26 are used to secure door hinges, which will be described later.

[0020] The aggregates used include vertical aggregates arranged above and below the direction of gravity, and horizontal aggregates that are perpendicular to the vertical aggregates (described later). These aggregates have cross-sectional shapes with high bending strength, such as L-shaped, Z-shaped, or hat-shaped cross sections. Additionally, areas that can be used as fixing brackets may be provided as appropriate.

[0021] The first vertical frame 20 is fixed to the side structure 100. The second vertical frame 24 is fixed to the end structure 102. Here, the first vertical frame 20 may be fixed to the side structure 100 directly, or may be fixed via a fixing bracket welded or bolted to the side structure 100. The second vertical frame 24 is fixed to the end structure 102 in the same way.

[0022] The first vertical ribs 20 and the second vertical ribs 24 are fixed at their lower ends to fixing brackets (hereinafter referred to as "floor fixing brackets 30") that are fixed to the floor and have an L-shaped cross section and a length equal to the width of the wall. Figure 3(a) shows the cross section. Figure 3(b) shows the cross section.

[0023] The floor fixing bracket 30 has a Z-shaped cross section with a surface 30a that protrudes to the outside 1 out of the frame unit and a surface 30b that protrudes to the inside 1 in of the frame unit separated by a height of 30h. A lower horizontal frame (material that connects to the lower ends of the inner vertical frame of the horizontal frame, described later) is bolted to the surface 30b that protrudes to the inside 1 in of the frame unit.

[0024] As will be described later, the support columns 22 are not fixed to the floor fixing brackets 30, but are only fixed to the first vertical ribs 20 and the second vertical ribs 24 via the horizontal ribs.

[0025] <Aggregate: Horizontal aggregate> Horizontal aggregates are placed between the first vertical aggregate 20 and the support column 22, and between the second vertical aggregate 24 and the support column 22. The horizontal aggregates include at least a first upper horizontal aggregate 40 placed between the upper end of the first vertical aggregate 20 and the support column 22, and a first lower horizontal aggregate 42 placed between the lower end of the first vertical aggregate 20 and the support column 22. The first lower horizontal aggregate 42 is fixed to a floor surface fixing bracket 30 (see FIG. 3).

[0026] Furthermore, horizontal aggregates corresponding to the horizontal aggregates arranged between the first vertical aggregate 20 and the support column 22 are also arranged between the second vertical aggregate 24 and the support column 22. In other words, a second upper horizontal aggregate 50 and a second lower horizontal aggregate 52 are arranged at least between the second vertical aggregate 24 and the support column 22.

[0027] Here, "corresponding" means that the first vertical aggregate 20 and the horizontal aggregate placed on the support column 22, and the second vertical aggregate 24 and the horizontal aggregate placed on the support column 22 are fixed at the same position on the support column 22.

[0028] In addition, both the first upper horizontal aggregate 40 and the first lower horizontal aggregate 42 are first horizontal aggregates, and the second upper horizontal aggregate 50 and the second lower horizontal aggregate 52 are second horizontal aggregates. In addition, both the first upper horizontal aggregate 40 and the second upper horizontal aggregate 50 are upper horizontal aggregates, and both the first lower horizontal aggregate 42 and the second lower horizontal aggregate 52 are lower horizontal aggregates.

[0029] This will be explained more specifically with reference to Figure 4. Figure 4(a) shows the cross section of Figure 4(b). The first lower horizontal frame 42 and the second lower horizontal frame 52 have plate-shaped width regions 42a and 52a facing the inner 1 inch of the cross section unit. Furthermore, the portions facing the support column 22 are provided with vertical wall-like portions 42b and 52b facing the support column 22 and having screw holes. The first lower horizontal frame 42 and the second lower horizontal frame 52 are fastened to the support column 22 with screws whose heads engage with T-grooves 22a and 22b formed in the support column 22, respectively.

[0030] Furthermore, the width regions (brackets) of the first lower horizontal frame 42 and the second lower horizontal frame 52 are fixed to each other by a generally hook-shaped diagonal connecting bracket 32. The width region of the first lower horizontal frame 42 is referred to as width region 41a, and the width region of the second lower horizontal frame 52 is referred to as width region 52a.

[0031] The other horizontal frames arranged on the first wall surface 10 and the second wall surface 12 are fixed to each other in the same manner. Therefore, the horizontal frames arranged on the first wall surface 10 side are connected to the horizontal frames arranged on the second wall surface 12 side at the same height. In other words, it can be said that the horizontal frames arranged at the same height are connected to each other by the diagonal connecting brackets 32 via the support columns 22.

[0032] The upper cross member has an L-shaped cross section and is folded back to the outside of the cross section unit. The folded back part is hidden by the ceiling panel. Figure 5(a) shows such a cross section. Figure 5(b) shows the cross section.

[0033] On the other hand, the lower cross member has an L-shaped cross section, but is folded back to the inside 1 inch of the cross member unit and fixed to the floor fixing bracket 30 (see FIG. 3(a)).

[0034] One or more horizontal frames may be placed between the upper horizontal frame and the lower horizontal frame. This is because horizontal frames can increase the support of the panel and the structural strength of the cross frame unit 1. Figure 2 shows two horizontal frames placed between the first upper horizontal frame 40 and the first lower horizontal frame 42. These are called the first upper auxiliary horizontal frame 44, the first lower auxiliary horizontal frame 46, the second upper auxiliary horizontal frame 54, and the second lower auxiliary horizontal frame 56, respectively.

[0035] At least one of the first upper horizontal frame 40 and the second upper horizontal frame 50 may be fixed to the ceiling structure 110. The frame unit 1 according to the present invention is easy to absorb distortion because the support columns 22 themselves are not fixed to the ceiling structure 110 and the floor structure 112, and the horizontal frames and panel members that provide structural strength are connected by T-grooves. Therefore, fixing at least one of the first upper horizontal frame 40 and the second upper horizontal frame 50 to the ceiling structure 110 actually strengthens the structural strength.

[0036] <Panel material> The panel material 60 is the surface that covers the 1 inch space inside the frame unit. Figure 6 shows a cross section of the panel material 60. The panel material 60 is a composite panel material in which a core material 64 is placed behind the surface of a top plate 62, and a back plate 66 is attached to the back surface of that. The panel material 60 is several mm thick, and can be fixed to other materials with rivets.

[0037] The panel material 60 can be formed according to the specifications of the first wall 10 and the second wall 12. FIG. 2 illustrates an example in which a vertically long first main door 14a and a first sub-door 14b are arranged on the first wall 10. A first upper panel 70 and a first lower panel 72 are arranged on the first wall 10. The first upper panel 70 has a gate-like shape and has a space for the first sub-door 14b. The first lower panel 72 is a long plate-like member (sleeve wall member) that continues from the side structure 100 side of the first upper panel 70. The first main door 14a is arranged between the first lower panel 72 and the support column 22. The second wall 12 is composed of a single second panel 76 that covers the entire second wall 12. However, a door may also be arranged on the second wall 12.

[0038] The panel material 60 arranged on the first wall surface 10 is called the first panel, and the panel material 60 arranged on the second wall surface 12 is called the second panel. More specifically, the first upper panel 70, the first lower panel 72, the first main door 14a, and the first sub-door 14b are the first panels. Furthermore, the second panel 76 arranged on the second wall surface 12 is the second panel. Of course, if a door is provided on the second wall surface 12, the panel material 60 of that door is included in the second panel.

[0039] These panel materials are fixed to the vertical and horizontal frames with rivets. More specifically, the panel material 60 is placed on the outer side of the frame unit relative to the vertical and horizontal frames, and holes are drilled in positions facing the fastening holes in the vertical and horizontal frames. These holes are not through holes in the panel material 60. Then, the vertical or horizontal frames and the panel material 60 are stacked and riveted from the inner side of the frame unit. This allows the panel material 60 to form the first wall surface 10 and the second wall surface 12, with the fixing rivets remaining hidden.

[0040] <Door material> Door material 80 is formed by surrounding four sides of panel material 60 with edging material 82. Figure 4 shows a cross section of the panel material 60 and edging material 82 connected together. The edging material 82 and the edge of the panel material 60 are overlapped and holes are drilled. At this time, the holes do not penetrate all the way to the front side of the panel material 60. The edging material 82 and the panel material 60 are then fastened together with rivets 84. This structure of door material 80 is commonly used for the doors of the cover unit 1 of the present invention.

[0041] Referring again to Figure 2(b), Figure 2 illustrates an example in which a first main door 14a and a first sub door 14b are provided on the first wall 10. The first main door 14a and the first sub door 14b are both fixed to the auxiliary vertical frame 26 on the side structure 100 side via hinges 90. The door material 80 and the hinge 90 are fixed with rivets 84, similar to the rim material 82. The hinge 90 and the auxiliary vertical frame 26 may be fixed with the rivets 84, or may be fastened with bolts via a connecting bracket.

[0042] A key 94 is provided on the support pillar 22 side of the door to normally prevent the door from opening. The key 94 for the first main door 14a is a bolt-type key in which the ends of upper and lower rods are rotatably hooked onto disks connected to the key 94. Rod receiving holes are provided in the first upper auxiliary horizontal frame 44 and the first lower horizontal frame 42.

[0043] Referring again to Figure 7, a U-shaped connecting member 94a is screwed to the first upper auxiliary horizontal frame 44, and an L-shaped angle 94b with a through-hole 94h is fastened to the U-shaped connecting member 94a. When the key 94 is turned, the rod 94c moves up and down and passes through the through-hole 94h of the L-shaped angle 94b, locking the first main door 14a.

[0044] The lock on the first sub door 14b is a latch type lock that rotates a cam on the inside of the locking unit when the key is turned, and the first sub door 14b engages with a cam receiver provided on the inside of the first upper panel 70. This lock also fits into the panel material 60 of the first sub door 14b. , and secured with rivets 84. [Industrial Applicability]

[0045] The present invention can be suitably used in passenger cars of railway vehicles. [Explanation of symbols]
