Description

Double-layer bedroom

The invention belongs to a double-layered bedroom, and particularly relates to a passenger car of a railway passenger car, a passenger ship, and a double-layered bedroom having a combined upper and lower sub-bedroom in a fixed building. Background technique

For long-distance railway trains, passenger ships and hotel rooms, providing sleeper conditions for passengers is a basic service item. In a limited space, it is the hope of the operator to arrange as many berths as possible and to improve the comfort of the berth as much as possible. At present, in most railway sleeper compartments, sleepers are arranged by 9 to 12 open, semi-enclosed or fully enclosed sleepers on one side wall of the carriage. There are two rows in each sleeper. Double or triple berth separated by partitions. The passengers in the middle and upper berths are up and down. China's current railway sleeper cars are 22- or 25-type railway hard sleepers, soft sleepers and high-class passenger cars. Among them, the soft sleeper car generally has nine door compartments, each of which has two upper bunks and two lower bunks, with a capacity of 36 people. The high-pack passenger car has fewer staff, only about 16 people. The shortcomings of the usual bunk arrangements for these railway sleeper buses are mainly the following:

1. The height of the upper bunk is too high from the floor. The passengers are difficult to work on the bunk, and the movement is complicated and inconvenient.

2. The bunk space is open and cannot provide separate and closed bedroom space for each passenger, lacking privacy and security. Even in a soft pouch with a door that can be closed, because it is a multi-person, if the companions do not know each other, or the men and women are mixed, there is still a problem of lack of privacy and security. Even in the double superior private room, because the two passengers are not necessarily acquainted, the gender is not necessarily the same, so the problem still exists.

3, the upper store does not provide passengers with a floor space for standing like a bed in a normal bedroom. Therefore, if the passengers on the upper bunk want to stand up, they can only climb down the ladder from the 1.5-meter-high bed. On the shared ground before the lower bunk, it is very inconvenient.

4, the upper store can not provide passengers with a comfortable sitting environment, the upper store passengers can only After the upper floor is laid down, temporarily take a seat on the lower bunk, or sit down on the simple folding stool on the side of the corridor. For the lower-street passengers, if the passengers who are borrowing are strangers, the time will often make both sides more embarrassing, affecting the mood of both parties.

5. The arrangement of the bunks makes it difficult for passengers to observe the view of the window in the lying position.

6. It is difficult to provide a stand-alone table for single use for each bunk.

7. The spatial layout of this kind of shop cannot make each passenger get the independent audio-visual facilities or the space environment required by the networked computer. This will become an insurmountable solution for the rapid development and popularization of multimedia and Internet technologies in trains and passenger ships. Obstruction.

8. The layout of this bunk cannot provide a separate use of sanitary facilities next to each passenger's bed.

In order to improve the comfort of the existing railway sleeper cars, at least partially solve or alleviate the problems as described above, in the Chinese patent documents such as 200420079476. 042, 98242058. 7, 200420005229. 6 respectively, various double layers are proposed respectively. The bedroom plan, which combines the necessary technical features that can be summarized as:

An upper sub-bedroom and a lower sub-bedroom which are combined with each other and disposed together in a space surrounded by the front wall, the rear wall and the left and right side walls; the upper and lower sub-bedroom doors are opened on the front wall; There is a shared hallway; the floor in the upper bedroom and the fixed bed form the penthouse ceiling in the lower bedroom.

Compared to the prior art of the previous railway sleeper compartments, these patented solutions provide a separate enclosed space for the upper and lower berths, and even provide a folding seat function. However, these programs also have the following major defects:

1. The height of the door of the upper bedroom is still too high from the floor of the corridor. The passengers in the upper bedroom still need to rely on the steep ladder to enter and exit the bedroom. The operation is still very difficult and not convenient.

2. The operation of the foldable bed plate proposed by the user is difficult for the customer and does not form an ideal comfortable seat structure and environment.

3. When this double-bedroom is used in a railway passenger car, each sub-bedroom is a separate box that is not connected to each other. Therefore, for two people who need to live together, this single-person box is not as good as a double-box. Although in the 200420005229. 6 patent also proposed a double box The plan, but this double private room is obviously not as good as a single person for passengers who wish to live alone. On the other hand, for railway operators, the ratio of single and double boxes cannot always satisfy the passengers' expectations. Summary of the invention

The basic object of the present invention is firstly based on the prior art to propose a two-story bedroom having a sitting and standing space, closed and independent of each other, and easier to access in comparison with the prior art.

The above basic object of the present invention is achieved as follows:

A double-layered bedroom comprising an upper sub-bedroom and a lower sub-bedroom which are combined with each other and disposed together in a space surrounded by a front wall, a rear wall and left and right side walls; a bedroom of the upper and lower sub-bedrooms The door is opened on the front wall; there is a shared corridor outside the door; the floor in the upper bedroom and the fixed bed form the penthouse in the lower bedroom;

a) the hallway floor is lower than the upper level bedroom floor, higher than the lower level bedroom floor; and:

The hallway floor is connected to the upper floor of the bedroom through the door of the upper bedroom and the steps;

The hallway floor is connected to the lower floor of the bedroom by the door of the lower bedroom and the steps;

b) the floor and fixed bed panels of the upper sub-bedroom, and at least three partitions between the upper sub-bedroom and the lower sub-bedroom, namely the transverse partition, the longitudinal partition and the under-bed partition, separating the upper and lower sub-bedrooms;

The bottom edge of the transverse wall is connected to the edge of the fixed bed board of the floor bedroom;

One of the two side edges of the transverse wall is connected to a side wall, and the other side is connected to one side of the longitudinal wall;

The other side of the longitudinal wall is connected to the front wall between the upper and lower bedroom bedrooms; the lower wall of the bed is sealed between the bed of the upper bedroom and the floor of the upper bedroom. The bed plate referred to herein refers to a plate for carrying a mattress and supporting the human body to lie down, and the "fixed bed plate" refers to a bed plate fixed to a base body (such as a wall body, a bracket).

The term "wall" as used herein refers to a slab wall used to separate spaces.

The term "front wall" as used herein refers to the wall of the double-bedroom bedroom that is adjacent to the front wall. The wall on the other side of the bed is the "back wall", and the left and right walls between the front and rear walls are "side walls". When applied to a railway passenger car, the "rear wall" refers to the outer wall of the car with the window.

In the existing RW25 type railway soft sleeper with 36 bunks, if the above technical features proposed by the present invention are applied, all the bunks can be improved to be closed and independent without expanding the car body volume and the car body size. Single-person bedroom, sitting and standing space in each sub-bedroom. In this kind of compartment consisting of single-person compartments, the number of single-car compartments has not only decreased, but has also increased to 44 to 48, and the space utilization rate has been significantly improved. Since the corridor floor is placed between the floors of the upper and lower sub-bedrooms, the doors of each sub-bedroom are connected to the corridors with similar steps, so that the passengers can walk on the ordinary steps without the use of the handrails. Very easy to get in and out of the bedroom. Of course, at both ends of the compartment, in order to connect with the ends of the ordinary compartment through the platform, several steps are required to be approached at the ends of the corridor floor of the compartment.

Compared with several prior patent solutions described above, the present invention adopts an elevated corridor floor and utilizes a plurality of partitions in the door of the lower sub-bedroom to surround the passengers and stand up and down the lower bedroom door. The space allows passengers to easily enter and exit the lower bedroom through one or two steps without bending down. Similarly, the upper bedroom can also be easily accessed by step. Therefore, it is more practical and achieves the basic object of the present invention.

Of course, although the invention is well suited for use in railway sleeper cars, it will be apparent that the scope of application of the present invention is not limited at all to railway cars. In some vehicles such as ships, long-duty road buses, and some large aircraft, the present invention can be applied with different dimensional changes according to different environmental requirements. Moreover, in addition to being in the vehicle, it is of course also possible to apply the invention in certain fixed buildings to obtain a comfortable bedroom with high space utilization, especially suitable for use in hotels, colleges and military quarters, or According to the features of the present invention, a double-bedroom unit that is standardized, modular, removable, dockable, and quick-disassembling can be made, so that a large number of single-person private rooms can be quickly assembled, and the space utilization rate is high. Dormitory, hotel.

Since the bed front of the bedroom has a floor between the front panel and the door, people standing on the indoor floor can sit directly on the bed. However, this sitting posture is obviously not as comfortable as the seat with the backrest, and the person sitting on the edge of the bed cannot observe the landscape outside the window on the rear wall in a natural sitting position. Therefore, a still further object of the present invention is to provide a more comfortable seating condition for indoor personnel on the premise of achieving the above object of the invention, and to make it easier to observe the scenery outside the window in a sitting position. This object of the invention is achieved by the following additional technical features:

a) a section of the bed in the middle of the bed of the upper and lower sub-bedrooms to the bed is a foldable bed that can be folded around the hinged axial direction of the middle of the bed;

b) There is a platform under the foldable bed board in the flat state, and there is a floor between the front and the side wall of the platform; the seat and the foldable bed form a seat, and the foldable bed plate with the angle adjustment mechanism is formed Adjustable angle backrest for the seat.

The term "orientation mechanism" as used herein refers to a mechanism utilizing the technical principle of a mechanism or device for adjusting and locating the fold angle of a foldable member applied to a seat or a folding bed in the prior art. It can be the simplest way to adjust the angle: Set the limit stop at the appropriate position on the seat wall to directly resist the reversible backrest (the above-mentioned foldable bed).

The term "bed" as used herein refers to a general term for all the components including a bed board and a mattress that constitute a bed that can be lying down.

As used herein, "bedside" refers to the side of the bed where the head of the human body is best suited to lie, and the opposite side is referred to as the "bed tail." For the beds described herein, the bed head is the end of the bed near the side of the door.

The term "seat" as used herein refers to a table or plate-like object suitable for people to sit on.

With the above additional technical features, the bed in the bedroom has the function of being converted into a seat with an adjustable backrest, which further improves the sitting condition in the bedroom. If a window is opened on the back wall of the bedroom, a person sitting on the seat with the adjustable angle back can observe the view of the window in a very comfortable sitting position.

Due to the use of the angle adjustment mechanism, the person lying on the bed can lean against the foldable bed when the angle between the foldable bed and the fixed bed is positioned at about 120 degrees.

In order to solve the contradiction between the single-person private room and the double private room existing in the prior art mentioned above, the present invention further proposes the following additional technical features:

Included in the at least two double-story bedrooms that are joined together side by side and share a corridor; the layout of the upper and lower sub-bedrooms of the two adjacent double-bedrooms are mirror images of each other; the two adjacent double bedrooms An inner door with a two-way anti-locking device is opened between the upper bedroom or the lower bedroom by a common side wall on the side of the doorway.

The "two-way anti-locking device" mentioned here may be a two-way anti-locking function in the prior art. Locks can also be an easier way: Install latches on both sides of the door. Its function is: Only the owners in the sub-bedrooms on both sides of the door agree and open the door locks or latches in their respective directions to connect the two adjacent sub-bedrooms. Moreover, people on both sides of the door can lock the inner door to prevent the other party from entering. Of course, it is also possible to add a third door lock based on this, which can only be opened by the manager. In this way, the manager can finally decide whether to open the door.

In order to make the aforementioned seat with the adjustable angle backrest more comfortable to sit, the feet can be stretched enough when sitting up, and the present invention further proposes the following additional technical features:

a) comprising at least two double-story bedrooms joined together side by side and sharing a corridor; b) wherein adjacent double-deck bedrooms share the same side wall;

c) The upper part of the double-bedroom or the lower-level bedroom of the adjacent two-story bedroom has a foot hole at the lower side of the front side of the adjustable angle seat, which is embedded in the other side of the side wall In the adjacent double bedroom.

The "stretching hole" referred to in this article is a cavity on the wall that can accommodate the feet that are stretched forward in a sitting position.

Since the width between the front and rear walls in the bedroom is larger than the width of the bed, and there is a floor space in front of the bed, in order to further utilize the space in the bedroom, the owner in the bedroom can provide a seat for the temporarily entering guest, and the present invention further The following additional technical features are proposed:

There is an additional seat in the upper sub-bedroom with a lower part of the vertical partition; the side of the door in the lower sub-bedroom has an additional seat between the front wall and the edge of the bed.

Now that a closed separate bedroom has been formed with additional seating and a floor, this provides the conditions for further enhancements in the bedroom. A still further object of the invention is to provide a wash basin in the bedroom. To this end, an additional technical feature of the invention is further provided: above the additional seat there is a wash basin hinged on the longitudinal wall or the front wall which is foldable between the vertical and horizontal postures.

In order to clear the water in the wash basin before it is folded to the upright position, it is obvious that the downward water pipe is led through a flexible hose connected to the bottom of the basin. However, the drawback of this method is that the lower pipe releases water at a slower rate. If the user flips the wash basin before the water is drained, it may cause the sewage to overflow the basin. To this end, an additional technique further proposed by the present invention The technical features are:

The wash basin has a main water tank at the front and a sub-sink at the rear with an opening facing the front edge of the wash basin. The rear wall portion of the sub-sink has a water outlet □ connected to the sewer pipe near the hinge shaft of the wash basin.

When the wash basin is turned up, the opening of the sub-sink is facing upwards, and the rear wall becomes the bottom of the trough. The sewage in the wash basin naturally flows into the sub-tank and passes through the rear wall of the sub-tank (that is, the bottom of the trough). The nozzle and conduit flow into the sewer line. In this way, the overflow of the sewage is avoided, and the water outlet and the water-tight component at the bottom of the ordinary wash basin are omitted.

The wash basin is a must-have item in the bathroom. Obviously, if there is another bathroom essential item in the bedroom - the toilet, the function is more perfect. Therefore, in order to increase the toilet facility, a further additional technical feature proposed by the present invention is that the additional seats in the upper and lower sub-bedrooms are flip-top seats hinged on the base with the rear edge hinged on the base. The board, and, there is a toilet under the seat board.

Thus, the toilet is directly coupled to the additional seat, and the foldable seat panel of the additional seat is the toilet lid.

Setting up the toilet in this small bedroom space will of course create two basic problems: How to deal with odor? Is it not elegant enough?

First of all, the odor problem can be solved directly by the usual means in the prior art, such as setting a negative pressure source in the toilet, so that the odor can be immediately sucked away. Of course, it is also possible to use a deodorant at the same time. An exhaust port is also provided in the bedroom to remove occasional spills.

As for the question of whether it is elegant or not, it should be said that this is a question that the customer can accept psychologically. In fact, for passengers, it is self-evident that it is more convenient to go to the public bathroom to use the toilet in the separate bedroom. This problem needs to be dealt with in the actual application according to the degree of public recognition. At the very least, it is possible to retain only the wash basin features. After all, the function of the wash basin is also important for people in the bedroom. Of course, if the size of the indoor space in the actual application allows, the wash basin does not have to be folded or retractable, but directly fixed.

When the invention is applied to a railway passenger car, it may be necessary to use a toilet. To increase efficiency, a toilet can be used for multiple double bedrooms at the same time. There are 44 single rooms in one section. The soft sleeper compartment can only use 6 toilets.

In the sub-bedroom with the above-mentioned adjustable angle seat, the side wall or the rear wall on the front side of the seat should of course be provided with a table that can be folded and retracted. Although this is not a necessary technical feature, it is obviously very useful. In addition, the sides of the foldable bed that serve as the side of the seat back are preferably also provided with retractable seat armrests.

The retractable table can be retracted directly from the existing technical features of the various retractable tables. For example, the simplest hinged hinge on the wall. If the structure behind the wall allows, a pull-out table hidden inside the wall can also be used.

The specific implementation of the retractable seat armrest has been made available in the prior art with proven solutions and technical principles. A simple method that is conventionally employed is to articulate at the left and right side edges of the face of the foldable bed that acts as the seat back.

In summary, the overall advantages of the above-mentioned all technical features proposed by the present invention can be summarized as follows: with respect to the main drawbacks of the prior art described in the paragraph of the Background of the Invention.

1. People in the upper and lower sub-bedrooms can easily enter and exit the door through the steps. This action does not even require the use of handrails for the average person, as long as the lift is raised like a normal staircase.

2. The space in the sub-bedroom is a closed cabin space, which provides an independent privacy space for the insiders. For single-person travellers, especially female travellers, the advantages of this secret, independent personal space are obvious. The soft sleeper carriage with 44 single-person private rooms of the present invention has an advantage over the existing soft-sleep passenger cars with nine 4-person private rooms (ie, 36 bunks).

3. Although the upper sub-bedroom proposed by the present invention is above the lower bedroom, however, unlike the upper bunk in the four-person private dining room of the traditional soft sleeper, this upper-level sub-bedroom provides indoors for the passengers. The condition of standing by the bed. Although the indoor standing space may not be sufficient, it is very beneficial to the living activities of passengers.

4. The function of the adjustable angle seat achieved by the present invention is clearly highly desirable for the passenger. People are not physically suitable for long periods of lying, nor are they suitable for sitting posture for a long time. The present invention provides the passenger with a bed that can be easily converted to each other and an adjustable angle backrest soft chair with armrests in the same bedroom. Compared to the existing patented technology mentioned in this article, this The bed and chair conversion operation is easier and more convenient, and the user can stand alone at the bedside with a simple lifting action with one hand.

5, because the foldable bed can be used as a cushion for the person lying on the bed by means of the angle adjustment mechanism, if the TV is installed at the appropriate position above the bed, then this is placed on the mattress with the backrest Watching TV is obviously very comfortable. Moreover, it is very easy to directly observe the scenery outside the window, whether sitting in the seat or leaning on the bed.

6. The front of the adjustable angle seat in the sub-bedroom has a very suitable position to accommodate the retractable table. This table is obviously very useful for passengers.

7. With a comfortable seat and a table in front of the seat, put a keyboard and mouse on the table, fix the flat panel display on the side wall behind the table, and connect the server through the cable. The ideal internet cafe room environment. The single bedroom room with internet access is fascinating for many long-distance travellers.

8. Since it is a private bedroom space, there is a practical possibility for an open wash basin and toilet. For long-distance travellers, it is obvious that the use of the toilet that can be used as an additional seat at the bedside can be used at any time. As long as the negative pressure mechanism already in the prior art is used, the odor can be eliminated in time.

9. The adjacent sub-bedrooms can be interconnected by opening the inner door so that two adjacent single rooms can be easily converted into double rooms. This feature is beneficial to both the passengers and the operators. It not only completely eliminates the contradiction between the single room and the double room, so that the operators can cope with the ever-changing single and double private rooms, and also let the "double room" Passengers can temporarily separate each other by closing the inner door as needed to avoid the noise of the other party. Wait until you wake up and then open the door.

detailed description

One embodiment having the essential features of the present invention is a two-story bedroom, the appearance and construction of which are illustrated in Figures 1 through 4. It is composed of an upper sub-bedroom and a lower sub-bedroom, and the upper and lower bedrooms share the front wall 1, the rear wall 2, the left side wall 3, and the right side wall 4. The floor 8-1 in the upper sub-bedroom is connected to the corridor floor 14 through the upper sub-bedroom door 12-1 by means of the step 11-1; the floor 8-2 in the lower sub-bedroom is passed through the lower sub-bedroom by the step 11-2. Door 12-2 is in communication with hallway floor 14.

In the upper bedroom, the fixed bed on the bed 9-1 is below the lower bedroom. That is to say, the fixed bed board 9-1 of the upper sub-bedroom also serves as a part of the ceiling of the lower level bedroom. The floor 8-1 of the upper level bedroom also doubles as part of the ceiling of the lower level bedroom. The lower sub-bedroom bed is located directly below the bed in the upper level bedroom.

The longitudinal partition 5 is partitioned between the upper bedroom bed and the front wall, and the upper and lower sub-bedroom doors 12-1, 12-2 are separated on both sides. The transverse wall 6 is connected between the longitudinal partition 5 and the right side wall 4, and the lower edge is connected to the front edge of the fixed bed plate 9-1 of the upper sub-bedroom. There is a distance of about 0.5 m between the horizontal partition wall 6 and the lower sub-bedroom door 12-2, which allows the person to stand upright and enter the lower sub-bedroom. Door 12-2. This space is also the location for people to stand in the lower sub-bedroom space.

The fixed bed board in the upper bedroom is 9-1 and the floor is closed to the floor 8-1 by the under-wall 7. The steps of the upper and lower levels of the bedroom are two levels, each step height is about 0. 25 meters. This height is the height that adults can easily get up and down without the need for handrails.

• Above the closed door panel of the transverse partition 6, the right partition 4, the longitudinal partition 5 and the lower sub-bedroom door 12-2, there is a top cover which constitutes the luggage compartment 13-1 of the upper sub-bedroom.

The recommended values for the main dimensions of this embodiment are: The height of the lower bed sub-bed 9-2 and the upper sub-bedroom bed 9-1 bottom is 0.95 m; the sub-bedroom door 12-1, 12-2 is high 1 9米, 0. 55米; bed length 2 meters, width 0. 8 meters; fixed bed board 9-1, 9-2 relative to the indoor floor 8-1, 8- 2 height 0. 5 meters; front and rear wall 1 9米。 The distance between the upper and lower sides of the bedroom floor 8-1 to the ceiling 40 1. 9 meters. The upper level of the bedroom ceiling 40 to the lower level of the bedroom floor 8-2 total height of about 3 meters.

The two sub-bedrooms of this two-bedroom have a volume of about 9.6 cubic meters, and each sub-bedroom has a square of 4. 8 cubic meters. The total volume of a common bedroom with the same indoor width, length and height is 2 meters x width 1. 6 meters X height 1. 9 meters = 6. 8 cubic meters. That is to say, this double-bedroom has obvious advantages in terms of space utilization. More importantly, this two-bedroom unit offers two upper and lower sub-bedrooms in a total height of about 3 meters, and each sub-bedroom has an upright living space of no less than 1. 9 meters.

The other side of the hallway of the two-bedroom can obviously also arrange another double-story bedroom of the same structure.

The mattress 10 above the fixed bed panel 9 and the mattress 25 above the foldable bed panel 16 are two portions of the same flexible soft mattress, the connected portions of which can be bent with the folding of the foldable bed panel 16. The flipped foldable bed 16 and the lower table 17 together form a chair. The foldable bed 16 on which the recliner 26 is mounted is the adjustable angle back of the seat. A mattress 25 and a soft backrest pad 19 are respectively mounted on both sides of the foldable bed board 16. There is also a soft seat cushion 18 on the seat 17. Two seat armrests 20 are hinged in the recesses of the foldable bed 16 on either side of the backrest pad 19. Seat The armrest 20 of the chair can only be retracted within a range of about 0 to 105 degrees under the restriction of the limit structure. The angle adjustment mechanism of the seat can be implemented using the technical principles of a wide variety of seat recliner mechanisms that have been widely used in the prior art. As long as the seat back can be leveled or steplessly adjusted in the range of 0-105 degrees.

There is a table 21 with a retractable retractable front in front of the seat.

Figures 9 through 12 show an embodiment of a double bedroom with the bed features shown in Figures 5-8.

In this embodiment, above the vertical partition 5, there are two steps of the main luggage rack 13-1 and the sub-tank 13-1-01. There is another secondary longitudinal wall 5-01 between the two luggage racks.

On the top of the retractable table 21-1, 21-2 in the upper and lower sub-bedrooms, there are sub-tables 21-1-01, 21-2-01 fixed to the side walls. The retractable table 21-1, 21-2 slides on the guide rails on the lower sides of the sub-tables 21- 1-01 and 21-2-01.

There is an additional seat 22 - 1 on the side of the platform 17-1 in the upper bedroom.

The doors of the upper and lower sub-bedrooms 12-1, 12-2 are sliding doors with upper and lower rails attached to the outside of the front wall. After opening, move the door panel to the middle of the front wall 1.

The middle level of the step 11-1 in the door of the upper bedroom is a recessed stepped step of about 15 cm in width and about 18 cm in depth at the side door. Such a shape can retract the two-stage structure into the room, and only a small cavity against the corner of the wall is left on the indoor floor 8-1. This step 11-1, which is set indoors, will avoid obstacles to corridor corridors.

The middle level of the step 11-2 in the door of the lower bedroom is a small bench-shaped step on the side door frame and the side wall. This small bench-style step 11-2 occupies only a small area of the interior corner and does not affect the activities of the indoor staff.

Of course, in order to prevent the floor 8-1 in the upper bedroom from being recessed, it is also possible to cover the cavity by means of a movable telescopic plate, a flap, etc., and then remove it when in use. The specific manner is various, for example, designed to be realized by a linkage mechanism that is linked with the door panel 12-1 of the door of the upper sub-bedroom by the linkage mechanism. When the door is opened, the middle level groove of the step 11-1 is exposed, and the door is closed after being closed.

In order to make full use of the height of the building space, reduce the height of the four walls of the entire double bedroom, 2米形成形成。 The floor of the upper level of the door is divided into two parts. The floor below the seat is about 0. 2 meters higher than the floor 8-1 at the door. An indoor table top floor 8-1-01. The gap between the high and low drops is enclosed by an additional lower bed 7-01. Both floors also serve as the ceiling in the lower level bedroom.

In this embodiment, the recommended main dimensions are:

The distance between the left and right side walls 3, 4 is 2. 35 meters, and the distance between the front and rear walls 1 and 2 is 1. 3 meters; the bed board (including the flattenable foldable bed board 25 and the fixed bed board 9) has a total length of 1.95 meters. Width 0. 76 m; The height of the bottom surface of the fixed bed board 9-1 of the upper sub-bedroom is 8.43 meters from the bottom floor of the lower floor bedroom floor. The height of the lower floor sub-bedroom fixed bed board 9-2 is 0 from the floor 8-2. 47 meters; the upper door bedroom door 12-1 door to the upper level bedroom floor 8-1 height is 1. 95 meters, the lower level bedroom door 12-2 door to the hallway floor 14 height is also 1. 95 The height of the door panels of the upper and lower bedroom sliding doors 12-1, 12-2 are 2.35 meters, width 0. 58 meters; the floor of the upper bedroom is 8-1 from the corridor The height of the height of the floor 14 is 0. 4 meters, the height of the floor of the lower floor is 8-2, and the height of the floor is also 0. 4 meters; the average step height of each step 11-1, 11-2 is 0. 2 meters; The height of the four walls of the double bedroom is 2.78 meters.

The total volume of the double bedroom of this embodiment is 2.35 meters long. X depth is 1. 3 meters X height 2. 78 = 8.5 cubic meters. The average volume per cubicle is 4.25 cubic meters.

Compared with the previous embodiment, the space utilization rate of the embodiment is further improved, and the step height of entering and exiting the door is also lowered. The sliding door method used has less interference with the living activities of the room personnel than the swing door method.

13 and 14 show a state in which a plurality of the above-described double-bedroom units are combined side by side in series. Each bedroom shares the same corridor. It can be seen that since the doors of the upper and lower sub-bedrooms all adopt the same outer dimensions and installation height, the neat appearance is more beautiful than the different heights of the above-described embodiments.

An embodiment of an optimized design of the present invention for use in a railway passenger car is shown in Figures 15 through 32.

The scheme is based on China's current Type 25 standard railway passenger car. The cross section of the outer wall 2-01 of the car is exactly the same as the cross section of the outer wall of the 25 passenger car. Its size conforms to the current national standard of China. Requirements for Locomotive and Vehicle Limits. Fig. 15 is a view showing the outline configuration of a double-bedroom unit in the embodiment.

According to this scheme, in a standard length (25500mm) 25-type compartment, 11 pairs of double-bedroom units can be arranged, and each pair of units is arranged on opposite sides of the central corridor.

In this scheme, the width of the corridor is determined to be between 0.75 and 0.8 meters. The interior width of the 25 passenger car is 2.9 meters and the net height is about 3.15 meters. According to this size, the relative height between the floor 8-1 of the upper sub-bedroom and the floor 8-2 of the lower sub-bedroom to the hallway floor 14 is 0.56 meters, single step 11-1 The height is 0. 28 meters. The spacing between the center lines of the left and right side walls (ie, the pitch of the compartment unit) is 1.96 meters; in order to widen the upper space of the standing position of the door of the lower sub-bedroom as much as possible, the fixed bed board 9-1 in the upper bedroom is gradually turned toward the tail of the bed. 5米。 The narrowest part of the bed is about 0. 5 meters.

The sub-bedroom doors 12-1 and 12-2 also use the sliding door method. The door height of the upper bedroom door 12-1 is 2.35 meters from the corridor floor 14, and the height of the corridor roof 33 is 2.1 meters from the corridor floor 14. Therefore, a cavity 34 is reserved in the hall roof 33 outside the threshold of the upper bedroom door 12-1. This recess 34 prevents the passenger from reaching the step 11-1 when entering the upper level bedroom door 12-1 when the head hits the corridor ceiling 33. Due to the presence of this cavity 34, the upper track of the upper sub-chamber door panel 12-1 should be placed in the middle of the hall roof 33, bypassing the cavity 34. To this end, the present scheme designs the upper sub-bedroom sliding door panel 12-1 into an end cap shape that is bent at the upper end toward the middle of the corridor ceiling 33 (see FIG. 16), and the upper end curved end cap 12-1-01 is along the corridor ceiling 33. The guide rails in the longitudinal grooves 33-02 on both sides of the middle portion slide.

In order to allow the passengers sitting on the back seat to comfortably extend forward far enough, the solution is provided at the front and rear side walls of the back seat in the upper and lower bedrooms. The foot holes 23-1, 23-2, the extension holes 23-1 of the upper bedroom, occupy a boss on the side wall at the corresponding position of the foldable table on the other side of the side wall. The position and volume of the boss does not interfere with the movement of passengers in the lower sub-bedroom. The front and rear foot holes 23-2 of the back seat in the lower bedroom are just embedded in the space below the fixed bed 9-2 of the other lower bedroom on the other side of the side wall, and will not cause passengers in the sub-bedroom. Any inconvenience.

In front of the backrest seats in the upper and lower sub-bedrooms, there are tables 21-1, 21-2 hinged to the side walls. Before you can flatten the foldable bed boards 16-1, 16-2, you should first fold the table 21-1, 21-2 turn up and lock against the wall. In this solution, the length of the foldable bed board 16 plus the length of the fixed bed board 9 is 1.8 m, which does not meet the length requirement of the standard bed, therefore, the table 21-1 in the upper and lower sub-bedrooms Next, each of the 21-2 has a long strip-shaped additional bed 9-1-01, 9-2-01 fixed to the corresponding side wall and having a width of about 15 cm.

A tablet display 28 is mounted on the side wall above the table 21. The table 21 can be placed with a keyboard mouse. The host computer can be centrally installed in the main unit and server room inside the car, and connected to the display and input device through cables. The computer monitor 28 can also act as a television screen at the same time. A television set 27 is also mounted on the fixed bed board 9. The television set 27 is suitable for passengers lying on the bed to watch. When the foldable bed 16 is at an angle of about 150 degrees to the fixed bed panel 9 as shown in Fig. 20, the passenger leaning against the mattress 25 of the foldable bed can watch the television in a comfortable and natural posture. 27 or the view from the window.

This feature is very advantageous for some passengers with motion sickness who are sensitive to the direction of travel of the train, as he can choose to look in the right direction to look at the window in a sitting or leaning position.

As can be clearly seen from Fig. 17, there is naturally a long hole available in the corridor floor 14 and in the corridor ceiling 33 for longitudinal passage through the entire compartment, the length of the long hole being sufficient to arrange various equipment piping cables. For example, air conditioning pipes, heating pipes, water pipes, vacuum pipes, power supply cables, communication cables, etc., can even be considered as installation space for water tanks and toilets. This space is located inside the insulated outer wall of the car, and has a better anti-freezing environment and maintenance environment (can be repaired when the movable floor is uncovered in the car compartment) than under the car chassis or outside the car roof. It is more suitable for installation and insulation. Water tank and toilet.

In the upper and lower sub-bedrooms there is an additional seat 22-1, 22-2 that can be folded over the seat, and below the additional seat are the toilets 37-1, 37-2. Above the additional seat, there are wash basins 31-1, 31-2 that can be folded and retracted. There are mirrors 39-1, 39-2 on the vertical partition 5 above the wash basin. These devices provide the necessary toilet conditions for passengers in a single bedroom.

The appearance configuration and use steps of the sanitary fixture in the lower sub-bedroom are shown in Figures 21 to 25. The sink structure of the wash basin 31-2 includes two parts: a front main water tank 31-2-01 and a rear sub-sink 31-2-02. The overall construction of the wash basin 31-2 is hinged to the wall by means of a shaft 31-2-03 and a limit locking mechanism. The opening of the sub-tank 31-2-02 faces the main water tank 31-2-01, that is, the phase For the main water tank 31-2-01, the sub-tank 31-2-02 is in a tipping state. When the hand basin 31 - 2 is turned down to the horizontal state, water can be injected into the main water tank 31-2-01 by means of the faucet 32 fixed on the basin edge, and when the waste water needs to be discharged after washing, the wash basin 31 can be directly lifted. -2, the water in the main water tank 31-2-01 which is tilted backwards flows into the sub-tank 31-2-02 which is upright, and along the water outlet 31-2-04 at the bottom of the sub-tank 31-2-02 It flows into the sewage pipe 36. The raised wash basin 31-2 can be kept upright by the locking mechanism, thereby giving up space for the lower additional seat 22-2 and the toilet 37-2. The seat panel of the foldable additional seat 22-2 hinged to the base acts as a toilet lid for the toilet 37-2. The faucet 32 is connected to the water supply pipe by a hose concealed in the basin. A mirror 39-2 is mounted on the wall surface above the wash basin 31-2. A sanitary product holder 41-2 is provided in the lower wall of the mirror 39-2 for placing the toiletries. The waste water of the wash basin 31-2 flows out through the sewage pipe 36 provided to the front wall 1. The sewer pipe 36 extends upwardly to the toilet 37-1 and the wash basin 31-1 in the upper sub-bedroom.

Similar to the sanitary equipment of the lower sub-bedroom described above, the external construction and use steps of the sanitary equipment in the upper bedroom are shown in Figs. 26 to 30. The structure of the wash basin 31-1 on the hinged longitudinal partition 5 through the rotating shaft and the limiting mechanism 31-1 - 03 also includes the front main water tank 31-1-01, the rear auxiliary water tank 31-1-02, and the installation The faucet 32 on the basin edge also has a water outlet 31-1-04 at the bottom of the sub-tank 31-1-01. Wash basin 31-1 has an additional seat 22-1 and a toilet 37-1. The vertical partition 5 above the wash basin 31-1 has a mirror 39-1, and a sanitary product holder 41-1 under the mirror.

The luggage compartment 13-1 of the upper sub-bedroom is located in the upper part of the upper top cover in the opening of the lower door bedroom door 12-2. Although the space position of the luggage rack is arranged above the fixed bed board 9-1 in the upper bedroom, in order to avoid the person who falls on the bed when the brakes are suddenly braked, the position of the luggage rack above the fixed bed board 9-1 is closed and used as Air conditioning duct and air outlet 35. The air conditioning vents of the lower sub-bedroom can be placed on the side of the corridor floor below the door 12-2.

The fixed deck board of the lower sub-bedroom 9-2 and the front wall 1 have the same height as the additional seat 22-2. The deck is the lower compartment of the luggage compartment 13-2 (see Figure 20).

The integrated control panel 38 and luminaire 30 are mounted on the walls in the sub-bedroom. The integrated control panel 38 can control indoor lighting, TV, computer, air conditioning, ventilation and other related equipment and call and alarm buttons. There should also be an automatic alarm of smoke and necessary automatic fire extinguishing facilities in the room.

There should be a negative pressure suction hole in the toilets 37-1, 37-2 connected to the negative pressure generating device via a pipe. When the toilet is used, the odor is discharged into the negative pressure hole in real time along with the air.

In order to widen the space on both sides of the bed, the glass and part of the windows 24-1, 24-2 should be mounted as close as possible to the outer surface of the outer wall of the car, and the window sill in the window 24 should be allowed within the limits allowed by the standard limits. Reduce to the height of the bed. In this way, the width of the space on both sides of the middle section of the bed can be up to 0.7 meters.

The length of the remaining two compartments is about 21. 6 meters (1960 X 11 ), and the total length of the remaining compartments is 3. 9 in a 25. 5 mm long compartment of a 25-type standard railway passenger car in China. Around the meter. Since there are wash basins and toilets in each sub-bedroom, there is usually no need to set up separate toilets and washrooms in such compartments. Therefore, the remaining total of 3. 9 meters of carriage space at both ends of the carriage is sufficient to arrange the door aisle, the crew room, the electric control equipment, and the electric hot water equipment. In this way, a total of 44 enclosed wheelchairs, bathroom fixtures, and single luxury sleeper cabins with audiovisual and internet access can be accommodated in a section 25 railcar compartment. The RW25 soft sleeper has an obvious advantage over the existing nine four-person box, 44-story.

Although there are many advantages to an independent single-person private room, it is obvious that in actual business operations, many passengers often need a double private room. If the entire carriage is a single-person private room, it will not be able to meet the requirements of this part of the passengers. However, if the railway operator wants to solve this contradiction by matching some double-person private rooms, there will be a problem that the fixed single-double private rooms can not meet the changing passenger demand.

To this end, in the embodiment shown in Figures 33 to 35, a two-way anti-lock is provided on the side wall between the adjacent adjacent sub-bedrooms in the adjacent two-bedroom unit with mirror images. Functional door locks for sliding door interior doors 29-1, 29-2. In this way, as long as the passengers in the two left and right adjacent sub-bedrooms agree, and the door locks in the respective directions of the shared inner door are opened, the two sub-bedrooms can be connected to each other through the open inner door. . The sliding door panel of the open inner door is retracted into the common side wall of the two sub-bedrooms. Since the feature of the protrusion holes 23-1, 23-2 in the foregoing embodiment cannot be achieved between the adjacent two-story bedrooms of the mutual mirror layout, in the present embodiment, there is no leg hole in the sub-bedroom. However, the experiment proved that the seat without the front hole is still quite comfortable and the passenger is completely acceptable.

Adjacent sub-bedrooms that are interconnected can be temporarily isolated from each other by closing the inner door at any time. As long as the sound insulation of the inner door is sufficient, this feature can solve the companion There is a problem of sleeping and snoring and unable to fall asleep.

The advantages of this passenger compartment with inner door for the operator are also obvious: it can always meet the needs of almost all passengers for single or double rooms. If there are certain legal or ethical requirements in certain areas of application, the operator can also add a third door lock to all interior doors – the administrator's door lock. If the administrator door lock is not opened, the inner door cannot be opened.

The same principle as the above-described scheme, and Figs. 36 and 37 show an embodiment of a double-layered bedroom with inner doors 29-1, 29-2 based on the basic features shown in Fig. 9. The adjacent two-story bedroom units are also mirror images of each other so that adjacent sub-bedrooms of the same floor can be joined to each other or independently of each other by switching the common inner door. This two-bedroom embodiment can be used in hotel room layouts or modularly assembled hotel facilities in fixed buildings. The operator of this hotel can flexibly provide single or double rooms according to the different needs of different customers.
