Capsule bed

Abstract

To provide capsule beds that offer excellent sound insulation and vibration damping when placed side by side. [Solution] A capsule bed 1 comprises a hollow columnar cylindrical body 2 having a living space inside, and closed ends 3 and 4 that seal both ends of the body 2, with an openable / closable opening / closing part 5 provided on at least one of the closed ends 3 and 4 at both ends. The closed ends 3 and 4 at both ends are configured to protrude from the body 2 in a flange-like manner. As a result, when multiple capsule beds are placed side by side horizontally or stacked vertically, adjacent capsule beds will be in contact with each other at the outer surfaces of the closed ends at both ends, creating a gap between the bodies of adjacent capsule beds. This gap prevents vibrations from the body from being directly transmitted between adjacent capsule beds, thereby enhancing the sound insulation and vibration damping effects between capsule beds.

Description

Technical Field

[0001] The present invention relates to a capsule bed which is a capsule-shaped bed having a bedroom space for sleeping inside.

Background Art

[0002] A narrow bedroom that is blocked from the outside by a capsule and forms a complete private room space is called a capsule bed (or capsule room) (see the Digital Daijisen). A capsule bed basically consists of a box body (housing) formed by a blind-ended cylindrical body having a living space inside, and has a configuration in which an entrance is formed on either the end face or the cylindrical surface. By arranging or stacking a plurality of capsule beds horizontally or vertically, a large number of living spaces can be formed in a limited space. In addition, the capsule bed is easy to carry, and since the internal living space can be blocked from the outside world, it can be used for group / collective activities and disasters / emergencies (see Patent Document 1).

[0003] Regarding conventional capsule beds, for example, those described in Patent Documents 1-12 are known. When classifying these conventional capsule beds (or capsule rooms) according to the outer shape of the box body, they are generally classified into (I) a rectangular parallelepiped type and (II) a hexagonal prism type (honeycomb type), and the hexagonal prism type is further classified into (IIa) a corner-bottom honeycomb type and (IIb) a flat-bottom honeycomb type, and can be classified into the types shown in FIGS. 14 to 16.

[0004] As shown in Figure 14, a rectangular capsule bed has a basic structure in which both ends of a rectangular cylinder are closed off with end faces to form a box-like body, and an opening / closing part (door, shutter, roll blind, etc.) for an entrance / exit is provided on one end face or the cylinder face (see, for example, Patent Documents 6-9). As shown in Figure 14, by arranging these individual capsule beds side by side or stacking them vertically, many living spaces can be created within a limited space. The interior of the box is equipped with interior facilities such as bedding such as mats or carpets, futons, pillows, interior lights, luggage racks, hangers, ventilation and air conditioning equipment, clocks, televisions, radios, and electrical outlets (see, for example, Patent Documents 6-9).

[0005] Furthermore, as shown in Figure 15 or 16, a hexagonal prism-shaped (honeycomb-shaped) capsule bed (or capsule room) has a basic configuration in which both ends of a hexagonal cross-section cylinder are closed with end faces to form a box-shaped structure, and an opening / closing part for an entrance / exit is provided on one end face (see, for example, Patent Documents 1-5). When these individual capsule beds are installed side by side or stacked vertically, there are arrangements with one vertex at the bottom as shown in Figure 15 (see Patent Documents 2, 3, 4) or arrangements with one side at the bottom as shown in Figure 16 (see Patent Documents 1, 5). By making the box-shaped structure a honeycomb, multiple capsule beds can be stacked in a honeycomb shape, accommodating many people in a small area without wasting space, and can therefore be used for group activities or in disaster / emergency situations (see Patent Document 1). Patent Document 1 shows a capsule bed in which the individual cylinders are joined together from the beginning and not separated individually, and the cylinder walls of adjacent living spaces are shared.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 10-018431 [Patent Document 2] Utility Model Registration No. 3165250 Specification [Patent Document 3] Japanese Patent Publication No. 2015-209684 [Patent Document 4] Japanese Patent Publication No. 2024-022408 [Patent Document 5] Japanese Public Gazette No. 49-045765 [Patent Document 6] Japanese Patent Publication No. 2002-295040 [Patent Document 7] Japanese Patent Publication No. 05-248107 [Patent Document 8] Japanese Utility Model Publication No. 56-091844 Specification [Patent Document 9] Japanese Patent Publication No. 2018-003434 [Patent Document 10] Japanese Utility Model Publication No. 57-147948 Specification [Patent Document 11] Publication number 01-039329 [Patent Document 12] Utility Model Registration No. 3113233 Specification [Overview of the project] [Problems that the invention aims to solve]

[0007] As mentioned above, capsule beds are often arranged side-by-side or stacked vertically, as shown in Figures 14 to 16, in order to create more living space within a limited area. When multiple capsule beds are arranged side-by-side in this way, the sides of adjacent capsule beds are in close contact, making it easy for vibrations to be transmitted. As a result, sounds and vibrations emitted from the living space inside adjacent capsule beds are transmitted to the next bed, causing inconvenience to the user of the adjacent capsule bed and disrupting their sleep.

[0008] Furthermore, in order to make effective use of the limited installation space, if multiple capsule beds are placed side by side as shown in Figures 14 to 16, the cluster of capsule beds becomes a wall-like obstacle that completely blocks airflow, resulting in poor ventilation between the capsule beds. Although the inside of the capsule bed is insulated by using insulation material in the body and closed ends, if the ventilation around the capsule bed is poor, hot air tends to accumulate around the capsule bed in the summer, and when the living space is ventilated with a ventilation fan or similar device, the surrounding hot air flows into the room, which is a problem.

[0009] Furthermore, since the inside of a capsule bed becomes an almost airtight space when the opening is closed, the humidity inside the room tends to rise, which can lead to a problem of increased discomfort index (temperature humidity index; THI) inside the room.

[0010] Therefore, an object of the present invention is to provide a capsule bed that offers excellent sound insulation and vibration damping between adjacent capsule beds when multiple capsule beds are arranged side by side horizontally or stacked vertically. A second object of the present invention is to provide a capsule bed that allows for good ventilation around the assembly of capsule beds when multiple capsule beds are arranged side by side horizontally or stacked vertically. A third object of the present invention is to provide a capsule bed in which the discomfort index inside the capsule bed does not easily increase. [Means for solving the problem]

[0011] The first configuration of the capsule bed according to the present invention comprises a hollow columnar cylindrical body having a living space inside, and closed ends that seal both ends of the body, and an openable / closable opening / closing part is provided on at least one of the closed ends at both ends, The closed ends at both ends of the body are characterized by protruding in a flange-like manner.

[0012] With this configuration, the closed ends at both ends of the body are configured to protrude from the body in a flange-like manner. When multiple capsule beds are placed side by side horizontally or stacked vertically, adjacent capsule beds will be in contact with each other at the outer surfaces of their closed ends, creating a gap between the bodies of adjacent capsule beds. This gap prevents vibrations from the body from being directly transmitted between adjacent capsule beds, enhancing sound insulation and vibration damping between them. Furthermore, airflow is maintained through this gap, ensuring air circulation between capsule beds, which reduces the accumulation of heat around the capsule beds, especially in summer. Additionally, the heat dissipation and moisture release effects on the surface of the capsule bed's body are enhanced, reducing the rise in room temperature, especially in summer.

[0013] Here, "flange-like projection" means that the outer circumference expands outward from the center, like a flange. In this invention, the "opening / closing section," which is the entrance / exit, may be provided at the closed ends of both ends of the body, or at the closed end of one end of the body. As the "opening / closing section," a door, shutter, roller blind, etc., can be used.

[0014] Furthermore, in the present invention, it is preferable that the closed ends at both ends of the body portion be formed such that the outer cross-sectional area is the same shape. When multiple capsule beds of the present invention are placed side by side horizontally or stacked vertically, if the outer cross-sectional area of ​​the closed ends at both ends of the capsule beds is the same shape, the space-filling rate of the capsule beds is increased and the stability of the placed capsule beds is improved.

[0015] Here, "circumferential cross-section" refers to the outer circumference of the cross-section of the closed end when the closed end is cut by a plane perpendicular to the central axis of the body. "Identical circumferential cross-sections" means that the circumferential cross-sections have the same shape. "Joining" means arranging them side by side in contact with each other.

[0016] In the present invention, it is preferable that the outer peripheral shape of the cross-section of the closed end portions at both ends of the body portion is a quadrilateral or a hexagon. If the outer peripheral shape of the cross-section of the closed end portion is a quadrilateral or a hexagon, when a plurality of capsule beds of the present invention are arranged side by side horizontally or stacked vertically and arranged side by side, the capsule beds can be arranged in the installation space with the densest packing, the utilization efficiency of the installation space can be maximized, and the limited space can be effectively utilized.

[0017] A second configuration of the capsule bed according to the present invention is that, in the first configuration, the body portion and the closed end portion are made of wood, and at least the outer surface of the side plate constituting the body portion is formed to have a rough surface structure having irregularities extending over the entire outer surface.

[0018] According to this configuration, by forming the body portion and the closed end portion of wood, a high sound insulation and moisture-proof effect can be obtained. The moisture-proof effect lowers the internal perceived temperature. The sound insulation effect blocks external noise and improves the habitability. By forming it into a rough surface having irregularities extending over the entire outer surface, a high temperature reduction effect, a high humidity dissipation effect, and a high noise diffusion effect can be obtained.

[0019] Here, the "rough surface having irregularities" can be an irregular stripe groove surface, a porous surface, a punching surface, a grained surface, an embossed surface, etc.

[0020] More preferably, the outer surface of the side plate constituting the closed end portion can also be formed to have a rough surface structure having irregularities extending over the entire outer surface. Thereby, a higher sound insulation and moisture-proof effect can be obtained.

[0021] A third configuration of the capsule bed according to the present invention is that, in the first configuration, the inner surface of the side plate constituting the body portion is formed to have a rough surface structure having irregularities extending over the entire inner surface.

[0022] This configuration allows for a rough surface with irregularities across the entire inner surface, resulting in high temperature reduction, high humidity dissipation, and high noise diffusion effects.

[0023] Furthermore, more preferably, the inner surface of the side plate constituting the closed end can also be formed to have a rough surface structure with irregularities extending over the entire outer surface. This provides a higher temperature reduction effect, humidity dissipation effect, and noise diffusion effect.

[0024] A fourth configuration of the capsule bed according to the present invention is characterized in that, in the third configuration, the inner surface of the side plate constituting the body is made of a plate material in which hexagonal recesses are uniformly formed over the entire surface.

[0025] This configuration, by forming the inner surface with a plate material that has uniformly hexagonal indentations across its entire surface, provides high temperature reduction, high humidity dissipation, and high noise diffusion effects. In addition, the hexagonal indentations increase the strength of the inner plate.

[0026] Here, "a board material with hexagonal indentations uniformly formed across its entire surface" can refer to a board material with hexagonal holes arranged in a mesh pattern (honeycomb wood), for example.

[0027] A fifth configuration of the capsule bed according to the present invention is that, in the second or third configuration, the side plates constituting the body are constructed by combining a plurality of unit wooden boards for side plates, The rough surface structure is characterized by a series of parallel, evenly spaced linear grooves formed on the surface of each of the unit wooden boards used for the side panels.

[0028] With this configuration, by creating a row of parallel grooves spaced at regular intervals, the sound reflected from the surface of the unit wooden boards used for the side panels is scattered (diffusely reflected) and diffused, resulting in a noise reduction effect.

[0029] A sixth configuration of the capsule bed according to the present invention is, in the first configuration, a leg member that supports the lower side of the torso, A leg ring provided at the lower end of the leg member, An adjuster for adjusting the height of the aforementioned leg member, It is characterized by having the following features.

[0030] This configuration allows for easy movement thanks to the wheels, making it possible for one person to transport it. Furthermore, the adjusters allow it to be fixed in place, ensuring stable mounting even on uneven ground.

[0031] Here, "caster" refers to a wheel (or wheel) whose direction can be freely changed. "Adjuster" refers to a component with a height adjustment function, mainly used to fine-tune the movement and position of machinery and equipment.

[0032] A seventh configuration of the capsule bed according to the present invention is characterized in that, in the first configuration, an electrical outlet or AC-USB power adapter for supplying electricity from the outside is provided in the living space within the torso.

[0033] With this configuration, by providing an electrical outlet or AC-USB power adapter, it becomes possible to supply power to or charge portable information devices indoors during a disaster.

[0034] An "AC-USB power adapter" is a type of AC adapter that converts household AC power into USB (Universal Serial Bus) power.

[0035] An eighth configuration of the capsule bed according to the present invention is characterized in that, in the first configuration, the wood constituting the body and the closed end is wood with a moisture content of 10% by weight or less.

[0036] This configuration, using wood with a moisture content of 10% by weight or less, provides a high moisture absorption effect. This reduces indoor humidity, lowers the perceived temperature, and improves living comfort.

[0037] The ninth configuration of the capsule bed according to the present invention is characterized in that, in the first configuration, the plate material used on the side surface of the body has a five-layer structure consisting of a wood veneer layer, a wood plywood layer, an insulation layer, a wood plywood layer, and a wood veneer layer from the inside out.

[0038] This configuration, with its five-layer structure as described above, also enhances impact resistance and heat insulation.

[0039] A tenth configuration of the capsule bed according to the present invention is characterized in that, in the first configuration, a waterproof and heat-insulating paint is applied to the entire outer surface of the body and the closed end.

[0040] With this configuration, applying waterproof and heat-insulating paint prevents water from leaking into the room during condensation, even when installed outdoors. Furthermore, applying waterproof and heat-insulating paint reduces the rise in indoor temperature due to sunlight when installed outdoors. [Effects of the Invention]

[0041] As described above, the capsule bed of the present invention has a configuration in which the closed ends at both ends of the central body of the capsule bed protrude in a flange-like manner. When multiple capsule beds are placed side by side horizontally or stacked vertically, a gap is created between the bodies of adjacent capsule beds. This gap prevents vibrations from the bodies of adjacent capsule beds from being directly transmitted, enhancing the sound insulation and vibration damping effects between capsule beds. This makes it difficult for sounds and vibrations generated in the room to be transmitted to the next bed, solving the problem of disturbing the user of the adjacent capsule bed or disrupting their sleep. Furthermore, because airflow passes through this gap, air circulation between capsule beds is ensured. In particular, during the summer, heat is less likely to accumulate around the capsule beds, reducing the rise in room temperature and improving the comfort of the occupants in the room during use.

[0042] Furthermore, constructing the body and closed end from wood provides superior sound insulation and moisture resistance. Additionally, forming the outer or inner surface of the side panels constituting the body (and closed end) with a rough surface structure that has irregularities across the entire surface provides superior temperature reduction, humidity dissipation, and noise diffusion effects, ultimately improving the comfort of occupants in the room during use.

[Figure 14]This diagram shows the basic configuration of a rectangular capsule bed. [Figure 15] This diagram shows the basic configuration 1 of a hexagonal prism-shaped (honeycomb-shaped) capsule bed. [Figure 16] This diagram shows the basic configuration 2 of a hexagonal prism-shaped (honeycomb-shaped) capsule bed. [Modes for carrying out the invention]

[0044] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. [Examples]

[0045] (1) Exterior configuration Figure 1 is a front view perspective of the capsule bed according to the present invention. Figure 2 is a rear view perspective of the capsule bed according to the present invention. The capsule bed 1 of this embodiment is made entirely of wood and comprises a hollow columnar cylindrical body 2 having a living space inside, closed ends 3 and 4 that seal both ends of the body 2 (front end and rear end), and an openable / closable opening / closing part 5 provided on the front closed end 3.

[0046] The body section 2 is formed as a hollow hexagonal prism with a cross-sectional shape perpendicular to the central axis (the central axis passing from the center of the back to the center of the front) being a regular hexagon. Similarly, the closed end section 3 on the front side and the closed end section 4 on the back side are formed as short hexagonal prisms with a cross-sectional shape perpendicular to the central axis being a regular hexagon. The body section 2 is constructed by combining multiple rectangular body plates 2a (unit wooden boards for side plates). In this embodiment, the capsule bed 1 is oriented such that one of the six sides of the hexagonal prism-shaped body section 2 and closed end sections 3 and 4 is the bottom surface, and the opposite side is the top surface. That is, it is a flat-bottomed honeycomb type capsule bed as shown in Figure 16.

[0047] The closed ends 3 and 4 are constructed by sealing the inside of the hexagonal frame wooden blocks 3a and 4a with board material. The outer cross-sectional shape of the closed ends 3 and 4 is formed to be the same. When multiple capsule beds 1 are placed side by side horizontally or stacked vertically, if the outer cross-sectional shape of the closed ends 3 and 4 at both ends of the capsule bed 1 is the same, the space-filling rate of the capsule beds 1 can be increased, and the overall stability of the assembled capsule beds 1 is improved.

[0048] Furthermore, in the capsule bed 1 of this embodiment, the closed ends 3 and 4 at both ends protrude from the body 2 in a flange-like manner. The width of the protrusion of the closed ends 3 and 4 from the body 2 is set to be about 2 to 5 cm. If it is less than 2 cm, when multiple capsule beds 1 are placed side by side, the width of the gap between the body 2 of adjacent capsule beds 1 will be too narrow, resulting in poor ventilation and reduced sound insulation. If it is greater than 5 cm, the volume of the body 2 will become unnecessarily small, resulting in poor space utilization.

[0049] The closed end 3 on the front side is provided with an opening / closing section 5 consisting of a single-leaf door that can be opened and closed (see Figure 1). The opening / closing section 5 is a rectangular door that extends almost the entire height from the bottom to the top edge of the closed end 3, with a hinge 5a on one vertical side of the door and a knob 5b (door handle) on the other. The knob 5b is provided on both the inside and outside sides of the door. Both sides of the closed end 3 are sealed with sealing plates 3b, 3b. The closed end 4 on the rear side is sealed entirely with sealing plate 4b. A window section 6 for letting in light is provided in the center of the closed end 4 (see Figure 2). In this embodiment, the window section 6 is a square, fitted double-glazed window (a window with a double-layered glass structure). By using a double-glazed window, sound insulation and heat insulation of the window section 6 can be ensured.

[0050] A ventilation grille 7 is provided at the upper center of the opening / closing section 5 of the closed end 3 on the front side for ventilating (supplying) the interior of the capsule bed 1. A ventilation grille 8 is also provided at the upper rear of the closed end 4 on the rear side for ventilating (exhausting) the interior. The ventilation grilles 7 and 8 are made of circular wooden boards with numerous ventilation holes. The door panel of the opening / closing section 5 on the rear of the ventilation grille 7 has a ventilation opening that connects to the interior space. The sealing plate 4a of the closed end 4 on the rear of the ventilation grille 8 has a ventilation opening that connects to the interior space. A waterproof outlet 9 is provided at the lower rear of the closed end 4 on the rear side for connecting an electrical cord for external power supply.

[0051] The capsule bed 1 is mounted on top of a frame 11 with four legs. The frame 11 is a platform on which a seat plate 10 is mounted and for adjusting the height of the capsule bed 1 during installation. A flat seat plate 10 is mounted on top of the frame 11, and the capsule bed 1 is mounted on top of the frame 11 via the seat plate 10. Each of the four legs of the frame 11 is equipped with an adjustable caster 12. As shown in Figure 2, the adjustable caster 12 is an integrated unit consisting of a caster 12a (leg wheel) that can rotate freely and an adjuster 12b with a base ring for grounding at the head of a height adjustment screw (lower end). This adjustable caster 12 makes it easy to transport, install, fix, and fine-tune the height of the capsule bed 1.

[0052] Furthermore, when using this capsule bed 1 indoors, such as in offices, warehouses, or gymnasiums, a coating is not required on the outer surfaces of the body 2 and closed ends 3 and 4. However, when installing and using it outdoors, such as in a plaza, a waterproof and heat-insulating coating is applied to the entire outer surface of the body 2 and closed ends 3 and 4. This prevents water leakage into the living space during rainfall or dew. In addition, applying the waterproof and heat-insulating coating reduces the rise in indoor temperature due to sunlight when installed outdoors.

[0053] (2) Construction of the unit wooden boards for the side panels Figure 3 is an enlarged perspective view showing the outer surface structure of the unit wooden boards used for the side panels 2a and 3b. Figure 4 is an enlarged perspective view of section A in Figure 1. Figure 5 is an enlarged perspective view of section B in Figure 2. Each unit wooden board for the side panels constituting the body panels 2a and 3b is made of wood, and its outer and inner surfaces are formed to have a rough surface structure with irregularities throughout the entire surface. Specifically, as shown in Figure 3, this rough surface structure is a row of linear grooves formed on the surface of each unit wooden board for the side panels at regular intervals parallel to the longitudinal direction of the board. This rough surface structure is similarly formed not only on the body panels 2a and 3b, but also on the outer surfaces of the frame wood 3a and 4a, the outer and inner surfaces of the door frame and door panel of the opening / closing section 5, and the outer surface of the window frame 6a of the window section 6.

[0054] Figure 6 is a broken perspective view showing the layer structure of the unit wooden boards used for the side panels, which are used for the body panels, the sealing panels at the closed ends, and the door panels at the closed ends. The unit wooden boards for the side panels are composed of a five-layer structure as shown in Figure 6, consisting of a veneer layer, a plywood layer, an insulation layer, a plywood layer, and a veneer layer from bottom to top. These five layers are bonded together with adhesive to form a single board. Cedar veneer can be used for the veneer layer. Coniferous plywood can be used for the plywood layer, and the plywood layer has higher strength than the veneer layer. Styrofoam (registered trademark: polystyrene resin insulation material manufactured by DuPont Styrofoam Co., Ltd.) or cellulose insulation material can be used for the insulation layer. On the surface of the veneer layer, which forms the outermost layer on both the front and back, a row of linear grooves is formed as a rough surface structure, consisting of parallel linear grooves arranged at regular intervals, as shown in Figure 6. In this way, by creating a row of parallel grooves at regular intervals, sound reflected from the surface of the unit wooden boards used for the side panels is diffusely reflected, resulting in a noise reduction effect. In addition, the rough surface structure increases the surface area of ​​the veneer layer. As a result, the absorption efficiency of moisture from the surrounding air is improved on the living space side, making it easier to lower the humidity in the indoor space and improving comfort. Furthermore, on the exterior side, the heat dissipation efficiency and moisture release efficiency from the outer surface are improved.

[0055] Furthermore, it is preferable to use wood that has been dried to a moisture content of 10% by weight or less for the body section 2 and the closed ends 3 and 4. By reducing the moisture content to 10% by weight or less, the moisture-proof and sound-insulating effects of the porous wood are further enhanced.

[0056] (3) Interior configuration Figures 7 and 8 are broken perspective views showing the interior of the capsule bed in this embodiment. Figures 7 and 8 show the interior of the body 2 excluding the top surface and the left side body plate 2a, with Figure 7 showing the rear side (side of the closed end 4) and Figure 8 showing the front side (side of the closed end 3). Figure 9 is an enlarged perspective view of the area around the headboard (shelves, with shelves) in Figure 7.

[0057] The inner surface (inside the living area) of the body plate 2a of the body section 2 of the capsule bed 1, the sealing plates 3b of the closed ends 3 and 4, and the door plate of the opening / closing section 5 also have a rough surface structure with irregularities covering the entire surface, similar to the outer surface. Specifically, similar to the outer surface, a row of linear grooves is formed on the surface of each side panel unit, parallel to the longitudinal direction of the board at regular intervals. Furthermore, this rough surface structure is similarly formed not only on the body plate 2a and sealing plates 3b, but also on the inner surface of the door frame of the opening / closing section 5 and the inner surface of the window frame 6a of the window section 6. This rough surface structure on the board surfaces has the effect of reducing noise by scattering noise emitted by the user in the living area. In addition, the rough surface structure increases the surface area of ​​the board surface in the living area, making it easier for the board material to absorb moisture in the room. As a result, the rise in humidity in the living area during use is mitigated, further improving the comfort of the occupant in the living area.

[0058] A headboard 15 is provided at the lower part of the back wall (inner wall of the closed end 4) on the rear side (side of the closed end 4) of the capsule bed 1. A ventilation fan 16 is provided in the ventilation opening at the upper center of the back wall (inner wall of the closed end 4). An interior light 17 is provided above the headboard 15 on the back wall (inner wall of the closed end 4). An outlet 18 and an outlet / switch 19 are provided on the top surface of the headboard 15. Outlet 18 has an AC outlet 18a for external power supply. Outlet / switch 19 has an AC outlet 19a for external power supply, a USB power plug 19b, and a ventilation fan switch 19c (see Figure 9). AC outlets 18a and 19a are outlets for supplying external AC power supplied from the waterproof outlet 9. USB power outlet 19b is an outlet for an AC-USB power adapter that transforms and rectifies the external AC power supplied from the waterproof outlet 9 and supplies it as power for USB charging. The ventilation fan switch 19c is a switch for turning the ventilation fan 16 on and off.

[0059] A knob 5c is provided on the door panel of the opening / closing section 5 on the front side (closed end 3 side) of the interior of the capsule bed 1, and a ventilation grille 20 is provided at the ventilation opening at the top of the door panel. In addition, a bolt lock 21 for locking the door from inside the interior is provided near the knob 5c on the door panel.

[0060] (4) Installation of capsule beds Next, we will describe the case where multiple capsule beds 1 are placed side by side. Figure 10 is a perspective view from the front of three capsule beds 1 placed side by side. Figure 11 is a perspective view from above of three capsule beds 1 placed side by side. Figure 12 is a perspective view from below of three capsule beds 1 placed side by side.

[0061] When multiple capsule beds 1 are placed side by side, as shown in Figures 10 to 12, they are arranged so that one side of the hexagonal ring-shaped frame wood 3a, 4a of the closed ends 3, 4 of adjacent capsule beds 1 are in contact with each other. In this case, as shown in Figure 10, if the height (distance from the bottom edge to the top edge) of the closed ends 3, 4 of one capsule bed 1 is h, then adjacent capsule beds 1 are arranged with alternating heights such that they differ in height by h / 2. In Figures 10 to 12, the height of the central capsule bed 1 is positioned at a height that is h / 2 higher than the heights of the capsule beds 1 on both the left and right sides. At this time, a seat plate 10 is attached to the bottom of each capsule bed 1, and a height-adjustable frame 11 is attached to the bottom of the seat plate 10 of the central capsule bed 1. Four adjustable casters 12 are provided on the bottom surface of the seat plates 10 of the capsule beds 1 on both the left and right sides, and adjustable casters 12 are provided at the lower ends of the four legs of the frame 11 of the central capsule bed 1. These adjustable casters 12 allow a single worker to move the capsule bed 1 when transporting it. Furthermore, when fixing the capsule bed 1 in a predetermined position, the adjuster 12b of the adjustable caster 12 secures the capsule bed 1 in that position and allows for fine adjustment of its height.

[0062] Two adjacent capsule beds 1,1 are connected only by one side of the hexagonal ring-shaped frame wood 3a,4a at their ends 3,4, creating a gap space G between the body sections 2,2. Therefore, this gap space G prevents vibrations from the body sections 2,2 from being directly transmitted between adjacent capsule beds 1,1, thereby enhancing the sound insulation and vibration damping effects between the capsule beds 1,1. Furthermore, as shown in Figures 10 and 11, the gap space G is open to the surrounding atmosphere, resulting in good ventilation of the capsule bed assembly 1. Airflow between the capsule beds 1 is ensured, and especially in summer, heat is less likely to accumulate around the capsule beds. In addition, the heat dissipation and moisture release effects on the body surface of the capsule beds 1 are enhanced, reducing the rise in room temperature, especially in summer.

[0063] (5) Lining with perforated plate In addition to the inner walls of the capsule bed 1 shown in Figures 7 to 9, a perforated plate 30 can also be used as a lining, having hexagonal grid holes 31 uniformly formed across the entire inner wall. Figure 13 shows an example of a perforated plate 30 used for lining. Figure 13(a) is a perspective view of the perforated plate 30, and Figure 13(b) is a plan view of the perforated plate 30. The perforated plate 30 is made of wooden plywood, and flat, hexagonal grid holes 31 are drilled through the entire surface of the plate in a grid pattern. This perforated plate 30 is attached as a lining material to the entire interior wall of the capsule bed 1 shown in Figures 7 to 9. By lining the interior wall of the capsule bed 1 in this way, the interior wall of the capsule bed 1 has a structure in which hexagonal recesses are uniformly formed across the entire surface, thereby improving impact resistance and heat insulation. Furthermore, because the surface area of ​​the interior walls increases, the moisture absorption capacity is also enhanced, which can further improve the comfort of the occupants in the room during use.

[0064] In this embodiment, an example of a flat-bottomed honeycomb type capsule bed was described, but the present invention can also be applied to rectangular parallelepiped type capsule beds as shown in Figure 14, and square-bottomed honeycomb type capsule beds as shown in Figure 15.
