Description

Technical Field

[0001] This invention relates to ship design, specifically to a shipboard sun protection handrail and passenger ship. Background Technology

[0002] With economic development, more and more passengers are traveling by passenger ship. Because ships may list and tilt on the water, handrails are needed in the ship's corridors.

[0003] Shipbuilding regulations stipulate that handrails or other support structures should be installed along all corridors within escape routes to ensure sturdy support at every step that may be present in passageways leading to assembly and boarding stations. Such handrails should be installed on both sides of longitudinal corridors exceeding 1.8 meters in width and transverse corridors exceeding 1 meter in width.

[0004] However, in actual operation, some passengers use the handrails in the corridors as clotheslines to dry their clothes. This poses a fire hazard. When the ship is in distress, passengers need to quickly evacuate through the corridors to the assembly station. Clothes drying on the handrails hinder passengers' evacuation, impede their rapid escape, and render the handrails useless, thus endangering their lives. At the same time, it also affects the aesthetics of the ship and the daily work of the crew in the corridors.

[0005] The above problems have caused great distress and difficulties for ship owners, and there is a particular need to design a new type of handrail to avoid this situation. Summary of the Invention

[0006] This invention addresses the problem that existing passenger ship corridor handrails are easily used by passengers to dry clothes, obstructing passage and posing safety hazards. It proposes a structurally sound anti-clothes-drying handrail that complies with ship safety regulations. This design retains the original safety and auxiliary function of the handrail while structurally eliminating the possibility of hanging clothes for drying. Furthermore, it adds practical functionality to meet the actual needs of ship operation. To achieve the above objectives, this invention is implemented through the following technical solution:

[0007] A marine sun protection handrail, the marine sun protection handrail comprising:

[0008] Handrails extend along the direction of the ship's corridor;

[0009] Several armrest seats, one end of which is fixedly connected to the armrest and the other end of which is fixedly connected to the armrest mounting seat of the bulkhead, so as to fix the armrest to the bulkhead;

[0010] The liner is fixedly installed between several armrest seats and the bulkhead, with the upper and lower ends of the liner abutting against the ceiling and the deck surface, respectively.

[0011] The top surface of the handrail has an alternating wave-like undulation along its length, forming multiple sloping sections that are inclined relative to the horizontal plane. The cross-section of the handrail is flat and has a width of 70-100mm.

[0012] Furthermore, the wave-shaped handrail has an inclination angle of 5° to 15° every 350 to 500 mm, and rounded corners are provided at the crests and troughs of the wave.

[0013] Furthermore, a 10mm wide × 10mm deep strip groove is formed on the bottom surface of the side of the handrail away from the bulkhead along the length of the handrail. An LED light strip is embedded in the groove. The LED light strip is connected to the ship's emergency power supply to provide decorative lighting during normal navigation and switch to emergency lighting mode in case of distress.

[0014] Furthermore, the height of the armrest seat is 60-80mm, and the armrest seat is provided with an L-shaped bracket and fixed seats and fixed rings fixed at both ends of the L-shaped bracket;

[0015] The L-shaped bracket has rounded corners at the corners;

[0016] The fixed seat abuts against and is fixedly connected to the bulkhead;

[0017] The handrail passes through a number of fixing rings of the handrail seat in sequence to be fixedly connected to the handrail seat. The handrail is provided with an annular groove corresponding to each fixing ring. The fixing rings of each handrail seat are respectively embedded in the annular groove and are flush with the outer surface of the handrail.

[0018] Furthermore, multiple countersunk bolts pass through the fixing seat, the liner plate and the handrail mounting seat in sequence to fix the handrail seat to the bulkhead and the liner plate.

[0019] The handrail mounting base is a U-shaped base that is vertically welded and fixed to the surface of the bulkhead. The end plate of the handrail mounting base is provided with threaded holes for connecting bolts, and the inner side of the end plate is provided with reinforcing ribs.

[0020] Furthermore, the interval between two adjacent handrail seats is 800-1000mm, the handrail is 1000mm from the upper surface of the corridor deck covering, and the distance between the handrail and the lining is 50mm.

[0021] Furthermore, the cross-section of the handrail is a flat, rounded rectangle with a width of 80mm;

[0022] The handrails are made of wood or fire-resistant fiberglass or PVC, and the handrail bases are made of stainless steel.

[0023] The lining is a composite rock wool board, which has two layers of stainless steel plates and rock wool inside the two layers of stainless steel plates.

[0024] The following is a slightly expanded version, which remains concise but is more persuasive:

[0025] The advantages of this invention are:

[0026] 1. Triple anti-drying mechanism: wavy inclined surface (5°~15° inclination per section) + wide flat cross section (preferably 80mm) + continuous fireproof lining on the inner side, clothes hangers cannot be hung securely and clothes cannot be bypassed, effectively eliminating the problem of illegal drying in corridors.

[0027] 2.

Detailed Implementation

[0037] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0038] To fully understand this invention, detailed steps and structures will be presented in the following description to illustrate the technical solution of this invention. Preferred embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0039] Reference Figures 1 to 4 As shown, this embodiment provides a marine anti-drying handrail, mainly installed on the bulkheads of escape passages such as passenger ship corridors. This handrail not only meets the mandatory strength requirements of shipbuilding codes, namely, being able to withstand a horizontal distributed load of 750 N / m along the corridor centerline and a vertically downward distributed load, but also solves the fire safety hazard caused by passengers illegally drying clothes. The specific solution is as follows:

[0040] The handrail 1 of this application extends continuously along the longitudinal (or transverse, depending on the corridor layout) of the ship's corridor, and is typically installed on one or both sides of the corridor bulkhead. The top surface of the handrail 1 is designed with a continuous, wave-like, alternating undulating structure along its length, forming multiple sloping sections inclined relative to the horizontal plane. Specifically, a wave cycle is formed every approximately 350mm to 500mm (preferably approximately 440mm in this embodiment), and the inclination angle of each sloping section is 5° to 15° (preferably approximately 6° in this embodiment). The crests and troughs are rounded (preferably with a radius of R10 to R20mm) to ensure a smooth feel and avoid sharp edges, thus preventing injury to passengers' hands.

[0041] The cross-section of the handrail 1 is a flat, rounded rectangle, preferably 80mm wide (ranging from 70 to 100mm) and approximately 30 to 40mm thick. This wide and flat design prevents common clothes hanger hooks (generally with an opening width of 40 to 60mm) from being effectively attached to the handrail, further preventing clothes from being hung out to dry. Meanwhile, the handrail 1 can be made of wood (with a waterproof and wear-resistant coating) or fire-resistant composite materials such as fiberglass and PVC to meet the fire resistance and lightweight requirements of ships.

[0042] On the bottom surface of the handrail 1 on the side away from the bulkhead 3, a strip-shaped groove 11, 10mm wide and 10mm deep, is formed along its length. An LED light strip 12 is embedded within this groove 11, and the LED light strip 12 is connected to the ship's emergency power system via a waterproof connector. During normal navigation, the LED light strip 12 provides soft decorative lighting, enhancing the aesthetics of the corridor; in the event of ship distress or power failure, it automatically switches to emergency lighting mode, providing passengers with a continuous evacuation guidance light source. This design combines functional and decorative lighting, avoiding the need for an additional separate emergency light strip in the corridor and optimizing space utilization. The LED light strip 12 serves as a low-level indicator light to guide passengers to evacuate quickly, avoiding the problem of separate emergency lights potentially being obscured by clothing.

[0043] Several handrail bases 2 are used to securely fix the handrails 1 to the bulkhead 3. Each handrail base 2 has a body height of 60-80mm (preferably 80mm in this embodiment), and is made of stainless steel (304 stainless steel), which is corrosion resistant and has high strength.

[0044] The handrail seat 2 includes an L-shaped bracket 21 and fixed seats 22 and fixed rings 23 at both ends. The L-shaped bracket 21 has rounded corners to prevent sharp corners from causing injury. The fixed seats 22 abut against the outer surface of the liner 5 and are fixedly connected to the handrail mounting seats 4 on the bulkhead 3 by multiple countersunk bolts passing through the fixed seats 22, the liner 5 and the bulkhead 3, so as to achieve a firm overall installation.

[0045] The handrail mounting base 4 is a U-shaped seat that is vertically welded and fixed to the surface of the bulkhead 3. Its end plate is provided with threaded holes for bolt connection, and the inner side of the end plate is provided with reinforcing ribs 41 to enhance bending and shear strength, ensuring that the handrail system can withstand the 750 N / m horizontal distributed load and 750 N / m vertical downward distributed load required by the specification.

[0046] The fixing ring 23 is a circular ring structure with an inner diameter slightly larger than the outer dimensions of the handrail 1. The handrail 1 passes through each fixing ring 23 in sequence, and an annular groove 13 is provided at the position corresponding to each fixing ring 23. The fixing ring 23 is embedded in the annular groove 13, and its outer surface is flush with the outer surface of the handrail 1. The embedded design eliminates protruding gaps, avoids potential injury to passengers' fingers caused by the protrusion of the handrail seat when the ship is rocking, improves safety and comfort, and is also more aesthetically pleasing.

[0047] The lining plate 5 is fixedly installed between several handrail seats 2 and the bulkhead 3, serving as physical isolation and fireproofing. The upper and lower ends of the lining plate 5 abut against the corridor ceiling and the deck surface (or the upper surface of the deck covering), respectively, forming a continuous baffle structure to prevent passengers from wrapping or hanging their clothing around the inside of the handrail. More preferably, the lining plate 5 adopts a rock wool sandwich panel structure, including two layers of stainless steel plates 51 and a core of rock wool 52, which has good fireproof and heat insulation performance (meeting the fire resistance requirements of Class A or Class B for ships), while being lightweight and rigid.

[0048] Regarding installation parameters: the center-to-center distance between two adjacent handrail seats 2 is 800-1000mm (preferably about 900mm in this embodiment) to ensure the overall rigidity and stability of the handrail. The vertical distance from the top surface of the handrail 1 to the upper surface of the corridor deck covering is approximately 1000mm (e.g., ...). Figure 1 The handrail is designed to meet the ergonomic height requirements of ship corridor handrails, making it easy for adults to grip naturally. The clear distance between the outer side of the handrail 1 and the backing plate 5 is approximately 50mm, which facilitates the insertion of passengers' arms for gripping while preventing clothing from passing through the gap.

[0049] The installation process is briefly described below:

[0050] 1) First, vertically weld and fix the handrail mounting base 4 to the steel structure surface of the bulkhead 3, and install the reinforcing rib 41.

[0051] 2) Position the lining plate 5 so that its upper and lower ends abut against the ceiling and deck surface, respectively.

[0052] 3) Align the fixing seat 22 of the handrail seat 2 with the mounting holes of the liner 5 and the handrail mounting seat 4, and tighten them with countersunk bolts so that the handrail seat 2, the liner 5 and the handrail mounting seat 4 are fixedly connected as one and form a stable support.

[0053] 4) Pass the handrail 1 with the processed wave shape and groove through each fixing ring 23 in sequence, ensuring that the fixing ring is embedded in the annular groove 13 and flush.

[0054] 5) Finally, embed the LED light strip 12 to complete the electrical connection and waterproofing.

[0055] The marine anti-drying handrail of this embodiment effectively solves the fire hazards, evacuation passage blockage, and aesthetic problems caused by passengers illegally drying clothes through a triple anti-drying design with a wave-shaped inclined surface, wide and flat cross section, and inner lining plate. At the same time, the embedded fixing ring, rounded corner transition, LED emergency lighting and other details are optimized to improve safety, aesthetics and practicality. The structure is compact and easy to install and maintain, and it is especially suitable for passenger ships, ro-ro passenger ships and other ships with high requirements for escape passage.

[0056] This invention also advocates for the protection of passenger ships equipped with the aforementioned sun protection aids.

It should be understood that the present invention is not limited to the specific embodiments described above, and the devices and structures not described in detail should be understood as being implemented in a conventional manner in the art. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention using the methods and techniques disclosed above, or modify them into equivalent embodiments with equivalent changes, without departing from the scope of the present invention. This does not affect the essential content of the present invention.
