Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for moving furniture and the like, and more particularly to a device for moving furniture and other indoor equipment to arbitrary positions using rails laid under the floor.

Today, the housing situation in Japan may be said to be far improved compared to before, but due to extremely high land prices, people are forced to live in houses that are less than half the size of those in Europe and the United States. And this situation is
There is little hope that the situation will improve in the future due to the concentration of the population in cities and the trend towards nuclear families, which will continue to accelerate. Therefore, it can be said that achieving effective use of limited area and space is the key to improving the lives of the people.

However, until now, housing designs in Japan have generally adopted the principle of one room for one purpose, with little consideration given to using one room for multiple purposes. Therefore, if we try to create a large number of rooms within a limited area, we have no choice but to reduce the area of each room, but on the other hand, the size of furniture has changed due to the Europeanization and luxury of the people. As rooms tend to get larger year by year, rooms that were already small are starting to feel even more cramped. Furthermore, once large furniture such as chests of drawers is installed, it is usually extremely difficult to move it and clean the dust from behind it, so it is unlikely that it will become a breeding ground for fleas and aphids over the years. Unavoidable. In particular, microscopic mites that nest in dust are
It is also a health problem because it can easily cause allergic symptoms such as asthma.

The third problem with large stationary furniture is
There is a risk of falling due to an earthquake. However, since Japan is an earthquake-prone country located on the Pacific Rim seismic belt, there is always a risk of being struck by an earthquake of moderate or greater magnitude.
Once an earthquake occurs, tall and large pieces of furniture are the first to fall.

As mentioned above, how to harmonize the tastes of the people who demand large, high-quality furniture for small houses, and how to improve the earthquake resistance of large furniture are important issues in this industry. As far as I know,
Effective answers to these questions have not yet been given. The present invention seeks to provide a suitable solution to these problems.

From the long experience of designing, constructing and selling housing, the inventor of the present invention was acutely aware that the above problem could not be solved without breaking away from the preconception of one room per use.As a result of various research, the following confirmed the fact.

(b) “Narrowness” unless one room is given versatility for multiple uses.
that it cannot be solved.

(b) Even if casters are installed to make furniture movable, it is difficult to move large furniture to a designated position. Additionally, the fact that the casters make the building even taller is a disadvantage when considering earthquake resistance.

(c) Rails can improve the defects mentioned in the first part of (b), but rails cannot be laid on carpet surfaces, and the defects mentioned in the second part of the same paragraph cannot be avoided even with rails. However, rails are best in terms of ease of movement.

(d) Furniture, etc. should be combined as much as possible to reduce the layout area.

(E) If the rails can be laid below the floor level, it will not only solve the problem (C) but also be advantageous in terms of earthquake resistance.

The present invention is based on the above knowledge, and its gist is to provide a slit in the floor surface corresponding to the rail laid below the floor, and to place a leg plate having wheels at the lower end on the rail. This means attaching any furniture or other indoor equipment to the leg plate. Adopting such a configuration provides the following advantages.

(i) Able to move furniture etc. smoothly with one finger.

(ii) Since there is only a thin slit in the floor surface, the existence of the slit can be completely hidden by laying a long hair carpet.

(iii) If multiple pairs of rails are laid in parallel, it is easy to store multiple pieces of furniture, such as storing medium-sized furniture inside large furniture, and small furniture inside medium-sized furniture.

(iv) Since the furniture is held in place by the leg plates between the underfloor surface and the rail, there is no risk of it falling over unless there is a severe earthquake that would cause the house to collapse.

(v) Due to the features mentioned in (ii) and (iii) above, it is easy to make the room versatile, and therefore the merits of a one-room room can be utilized to the maximum extent.

(vi) Since furniture etc. can be easily moved, cleaning can be carried out thoroughly, which is extremely hygienic, and at the same time, it is healthy because the risk of allergies due to dust mites is drastically reduced.

(vii) If the rails are given an appropriate slope, furniture, etc. can be automatically moved to a predetermined position or their height can be adjusted.

(viii) The back side of furniture etc. becomes available. This feature is extremely useful in practice in that it makes it easier to use deep furniture, for example, or it allows you to utilize both sides of a cupboard.

(ix) The effort required to move furniture, etc. is significantly reduced, and no damage occurs due to the movement.

(x) There are no impressions on the carpet.

() You can move a large planter or aquarium to a sunny or sunny location depending on your preference. In particular, the latter type of aquarium is heavy, so being able to move it freely has great benefits.

() It is also possible to easily rearrange offices, stores, etc.

() Small area can be used effectively,
Improves livability and workability.

() It becomes possible to lead a functional life and work that eliminates waste.

There are still many advantages of the present invention, but other advantages can be easily deduced by experts based on the disclosure of the present invention.

The furniture to which the present invention is applied includes not only so-called furniture and fixtures, but also indoor equipment of considerable size, partitions, and the like. Examples include chests of drawers, beds, cupboards, cupboards, sideboards,
display shelves, show cases, dining tables,
There are desks, chairs, bookshelves, reception sets, dressing tables, refrigerators, washing machines, dryers, sewing machines, large planters, aquariums, and more. These indoor equipment items are stored singly or in combination depending on the purpose, and are used either in their current location or moved to a desired location. When adopting a composite format in which furniture etc. are combined and stored, there are countless combinations, but some suitable examples include sink-refrigerator-dining table-sideboard, desk-chair-bookshelf, and reception set. - Sideboard, bed - sideboard (or bookshelf or dressing table), sink (or washing machine) - dryer, dining table - sewing machine, decorative shelf - aquarium, etc. In particular, if the furniture that is the subject of the invention can also serve as a partition, such as a closet unit or a set between a closet and a floor, it is possible to freely divide rooms as desired and also freely change the size of each room. This is advantageous in practice. Note that the house to which the present invention is applied is usually a residence, but it may also be an office, a store, etc., if desired.

The indoor equipment described above is attached to leg plates that can slide on rails laid under the floor. This leg plate is made from a metal plate with a thickness of several millimeters, has wheels on its lower edge, and its upper part protrudes above the floor surface through a slit cut in the floor plate. Therefore, the width of the slits drilled in the floorboards can be within several millimeters, so if a long pile carpet is laid, they will be hardly noticeable, and after the indoor equipment is removed, the slits can be used as a wide floor surface. It is preferable that the parts of the leg boards that protrude above the floor are not exposed as much as possible, or that they are given a design, color, etc. that matches the furniture.

The rails are generally laid parallel to the floorboards, but some may have sloped sections if necessary. This inclination is used, for example, to provide a run-up to furniture etc. to make it easier to pull them out or store them, or to change their height to suit storage and use. For example, if you want to store a dining table above the sink, it will be difficult to do so because there is a slight difference in height between the two, but if you create a downward slope in the middle of the rail, until the table moves to the specified position. If the device is designed so that it can be lowered to a desired height, conflicts caused by the difference in height between storage and use can be easily resolved. Note that the number of pieces of furniture that can be placed on a pair of rails is not necessarily one, but if you want to accommodate another piece of furniture inside another piece of furniture, as a general rule, provide multiple pairs of rails that share the same axis. There is a need. In this case, as a general rule, the width of the rail is made larger for the outer furniture and smaller for the inner furniture.

The rails may also be curved or crossed if desired. In particular, if a turning table is provided at the intersection, furniture, etc. can be moved in the right angle direction, which is convenient for rearranging the room. However, in these cases, it is a good idea to make some changes to the foundation itself so that the joists do not get in the way.

It is preferable that the surface on which the rails are laid is relatively close to the lower surface of the floorboard. Ideally, the upper edge of the supporting wheel should not touch the underside of the floorboard. In this way, the inclination of furniture, etc. due to an earthquake is prevented by the contact between the wheels and the lower surface of the floorboard, so that overturning is effectively prevented.

The movement of furniture, etc. in the present invention is usually performed manually. Since the furniture is mounted on wheels mounted on rails, even large and heavy furniture can be moved manually without any problem. However, if the need for frequent movement is expected, such as when storing a desk or cupboard over a sink, it is necessary to apply rotational force to the wheels themselves or attach the mounting base to a rope, chain, or piston. It is advantageous to provide self-propulsion by known means such as traction. In particular, it would be most convenient to use a motor, chain, sprocket, etc., or to automatically move stepwise to a plurality of predetermined positions using an air cylinder or the like. In addition, when moving the furniture manually, it is preferable to add a brake or a stopper so that the furniture etc. can be fixed at a predetermined position.

In addition to the above, there may be various additional devices for effectively utilizing the device of the present invention. Examples of such methods include means for connecting and moving a plurality of pieces of furniture and automatically disconnecting them at a predetermined point, or means for making furniture such as tables foldable for convenient storage. However, since all of these means can be achieved by means known per se, it will be easy for experts to make inferences based on the disclosure of this specification.

The optimal target for implementing the device of the present invention is a relatively large room, for example, a room where a living room and kitchen are combined (LDK). The rail is preferably laid along the longitudinal direction of the room starting in front of the sink, and a cupboard, dining table, reception desk, sofa, etc. can be slidably placed on the rail. With this configuration, you can pull out the cupboard to cook, pull out the dining table to eat, and when finished, store them in their original position and pull out the sofa and reception set to relax or socialize, making it possible to use a small space. The area can be used most effectively depending on the purpose. In addition, even if guests come to cook, they will not be able to see into the kitchen, and when a large number of people gather for parties, memorial services, etc., all the furniture can be moved toward the wall, so there is no need to worry about moving heavy furniture. Therefore, it is ideal to provide rails that extend as far as possible into each room so that the room can be completely emptied if necessary. Although the above description has been made for residences, the device of the present invention can also be applied to stores, offices, etc. In these cases as well, the furniture can be easily moved, making it easy to redecorate. be.

Hereinafter, embodiments of the invention will be described with reference to the accompanying drawings, but the descriptions are of course illustrative and are not intended to limit the technical scope in any way.

FIG. 1 shows a partial plan view of a house in which the invention is implemented. In the drawing, in the center of the floorboard F of a relatively large room 1 that serves as a living room, dining room, and kitchen, there are three slits 2, which share an axis from the kitchen unit K at one end to the opposite wall.
2' and 2'' are bored, and a rail (indicated by a dotted line in the figure) is provided below each slit.In this example, a unique combination type kitchen unit described later is used, so the intermediate slit 2',
2' is the longest, followed by the outer slit 2,
2 and the length gradually decreases toward the inner slits 2'', 2''.

The relationship between each of the above rails and the leg plates placed thereon is shown in the following FIG. 2. Each rail 3,
3', 3'' are attached to the lower surface of the floorboard ( ), and the boxes 5, 5', 5' and 3' are made of upward U-shaped angles supported downwardly and laterally by joists 4, 4'.
It is formed by raising the bottom part of 5" upward. Leg plates 7, 7', 7" made of iron plate with a thickness of 5 mm.
pass through each slit portion of each lid plate 6, 6', 6'' with a slit covering the upper opening end surface of the rail box 5, enter the box 5, 5', 5'', and enter the box 5, 5', 5'' at the lower end thereof. are fork-shaped bearing fittings 8, 8',
8'' is welded, and wheels 9, 9', 9'' are pivoted to the metal fittings. A long-pile carpet 10 is laid on the upper surface of the floorboard F, and the ends of the carpet 10 are wrapped around the floorboard F, making the existence of the slits 2, 2', and 2'' almost invisible. Prevents dust and foreign matter from entering.

As will become clear below, the width of the leg plates 7, 7', 7'' is determined by the depth of the furniture, etc. to be attached.
For cabinets that can be supported by a single bottom plate even though they are not very deep, the width of the main leg plate should be approximately the same length as the depth. In this case, at least two wheels are required along the depth direction. On the other hand, in the case of a table in which the load in the depth direction is shared between two legs, it is appropriate that the leg plate be as narrow as the width of the leg with one wheel. It is best to make the leg plates as inconspicuous as possible. For this reason, for example, it is inserted into the inside of a leg of furniture or the like, or placed along the inside of the leg. Particularly in the case of items such as cupboards and chairs that have a large weight or are subject to a large load, it is preferable to bend the tips of the leg plates inward at right angles to support the load. At this time, the load bearing capacity can be increased by extending the bent end sides of both leg plates and integrating them, if necessary.

3 and 4 are a front view and a side sectional view of the kitchen unit K shown in the previous two figures. This unit consists of a top bag 11 attached to the top, a sliding cupboard 12, and a sliding table 1.
3 and a footrest 14, a sliding combination of a storage compartment 15 and a refrigerator 16, a fixed sink and cooking table 17, and a fixed shelf 20 below the top bag 11. Among the unit components mentioned above, the cupboard 12 is placed on the outer rails 3, 3 (see Figures 1 and 2 below) by the leg plates 7, 7, and the table 13 and footrest 14 are mounted on the leg plates 7, 7. 7', 7';7',7' are placed integrally on the intermediate rails 3', 3', and the connection body of the storage compartment 15 and refrigerator 16 is mounted on separate leg plates 7'',
7''; It is placed on the inner rails 3'' and 3'' by 7'' and 7''. The cupboard 12 is divided into two parts, front and rear, by a partition wall 12a, and the outside (left side when facing the drawing)
The inner portion 12A is configured as a Western liquor shelf and display shelf, and the inner portion 12B is configured as a cupboard.
2a, 12a; 12b, 12b... As shown in the figure, the storage compartment 15 and the refrigerator 16 are of the extraction type, facing each other, and are integrally connected by magnets 18, 18' attached to their respective opposing surfaces. When the protruding locking pin 19 moves forward to a predetermined position (for example, the front end position of the sink 17),
Further advancement is prevented by the pin 19, and as a result, only the refrigerator 16 can be advanced to an arbitrary position. A fixed shelf 20 is also provided on the wall behind the sink 17 to store cooking utensils.

All of the above-mentioned storage compartments and refrigerators are constructed so that they can be pulled out manually, but if necessary, a spring may be installed on the wall at the back of the storage compartment 15 or on the back of the storage compartment, and/or a spring may be installed on the back of the storage compartment 15 and/or a rail 3' It may be configured such that the storage compartment 15 is automatically moved to the stop position by giving a slight inclination to the storage compartment 15 and applying a slight starting force.

To use the above system kit, for example, do the following: That is, referring to FIG. 1, when cooking first, pull out the cupboard 12, table 13, refrigerator 16, and storage container 15 to the positions indicated by chain lines in the figure, and then take out the necessary ingredients from the storage containers and the refrigerator. , 15 and 16 to the sink 17
Then, the cooking utensils are taken out from the fixed shelf 20 and cooked, and then the cooked food is placed on the plate using the cupboard 12B, and then,
The table 13 is pulled out to an arbitrary position and food is served. When the meal is finished, the table and cupboard are put back into place. Incidentally, in the illustrated device, cupboard 1
A hatch H is bored at the bottom of 2, and when the upper table, which is served on the back side of the cupboard, is pulled out, the food will pass through the hatch and exit to the front side.
There is no need to transport food items one by one using trays or wagons, which reduces the labor of housewives. Similarly, when cleaning up after a meal, all you have to do is push the table away.

Furthermore, when a table is needed for guests, relaxing after a meal, etc., move the table 13 to the L side of the living room as shown in the chain line and use the chairs C and C that are already placed.
Construct a reception or relaxing set using... Furthermore, if you want to enjoy Western alcoholic beverages by yourself or with close friends, the table 13 is pulled out about 30 cm in front of the cupboard 12 where Western alcoholic beverages are displayed. Since the footrest 14 moves together with the table 13, and the height of the table is slightly higher than that of a normal table, the user can enjoy the taste of a home bar with the same feeling as being at a bar. At this time, if you leave enough space between the table 13 and the cupboard 12 so that a person can stand, and have a wife, young lady, etc. serve, you can create an atmosphere similar to that of a bar, so your boss, customers, etc. It can give satisfaction to people such as: Note that the panel 21 has a spring-loaded hinge 21 on the bottom surface of the table 13 in this example.
Since the panel is attached through the hinge 21b and is divided into two by the hinge 21b, it is curved vertically in a ``H'' shape so as not to get in the way of the legs in the illustrated usage state. In the stored state shown by the solid line in the figure, the cabinet 1 is in a straight line.
Shield the lower part of 2.

Of course, the usages described above are just a few examples, and it goes without saying that there are many other uses depending on the user's ingenuity. for example,
The table has many uses such as a party table, ironing board, sewing machine table, ping pong table, etc. Regardless of how it is used, the kitchen area is completely invisible to guests or family members, so even if it is a single room, it does not harm the harmony of the room, and a relatively small room can be utilized to a high degree. When all the furniture is stored, the spaciousness of the room is emphasized and it does not feel cramped. Moreover, the presence of a large cupboard in the front gives the viewer a sense of luxury. In addition, in this example, as shown in FIG. 5, the rails 3'c, 3'c in the living room L part are connected to the rails 3' in the DK part due to the inclined part 3'b in the middle.
It is slightly lower than tables a and 3'a, and can be lowered to an appropriate height as a reception or relaxing table. However, in this case, if another table is placed on the rails 3', 3' as a reception table, there is no need to provide the inclined portions 3'b, 3'b.

Figure 6 shows sofa S placed along the wall of the living room.
An example is shown in which the rails 3, 3 are laid parallel to. A reception table 13' and a pair of chairs C, C' are placed on the rails 3, 3, as in the previous example.
In this example, when not in use, chairs C, C' and table 13' can be placed against the corner of the room.
Significant space savings can be achieved.

Figures 7 and 8 show four pairs of rails 3, 3; 3', 3' and 3'' below the floor on the L side of the living room in Figure 1.
3″: Lay down 3,3 and place a bookshelf on each rail.
This is an example in which BS, desk D, and chair C are mounted. Bookshelf B
The widths of the rails 3, 3 and 3', 3' are wide, so that the desk D placed on the narrower rails 3'' and 3'' can fit inside this bookshelf, and the chair C can fit under the desk, respectively. It's summery. Therefore, if the desk D and chair C are pulled out and used when in use, and the desk and chair are stored when not in use, space can be significantly saved. The bookshelf in this example is large and divided into two rows, front and back, and it is necessary to move the bookshelf itself to take out books in the back row, but this bookshelf is supported by four rails. Therefore, the user does not feel the weight. Note that the combination of this example can also be applied to other combinations such as a combination of a large chest of drawers and a small chest of drawers or a dressing table.

FIG. 9 is a schematic diagram of a turning device R having two pairs of mutually intersecting rails. The rails 3, 3 and 3', 3' (see also Fig. 10), which intersect at right angles to each other, are cut at the intersection, and the rails 23, 23 laid on the rotating table 22 are located at this cut part. . The platform 22 is supported by a circular rail 25 via casters 24, 24, . . . and can rotate around an axis 26. According to this method, it is possible to move indoor equipment toward any wall in the room, which is extremely convenient when rearranging or repairing a room.

FIG. 10 is an example in which the turning device shown in FIG. 9 is combined with the device shown in FIG. 7. In this example, the bookshelf
A display shelf B is installed in place of the BS, and an aquarium Aq, which forms part of the display shelf, can enter the interior of the shelf by riding on a rail similar to that shown in FIG. In this example, when cleaning the aquarium Aq, first move the aquarium Aq to the side using the turning device R shown in Fig. 9, move the kitchen unit K to the living room L side, and then use the device R. Then, carry Aq to the sink and clean it, then move Aq to the side again, return K to its original position, and finally put Aq in the specified position. Incidentally, in this explanatory example, since the size of R is small, it will take some effort to replace it, but R
If the diameter of K is large enough to allow K to pass through, it will be much simpler. As is well known, indoor aquariums are the best decoration for living rooms, etc., but the main reason why they are not popular is that they are difficult to clean. However, according to the device of the present invention, cleaning is easy because no effort is required to transport the aquarium, and the aquarium fish in the aquarium will not die of disease and can permanently enjoy the enjoyment of an aquarium.

FIG. 11 shows an example in which the device of the present invention is used as a room partition, which is different from the previous examples. In this example, each partition is, for example, a set 27 for an alcove and a closet, and a set 2 for a wardrobe and a Japanese dance.
8. A wardrobe and a closet set 29 are each constructed as a set, and both are placed on rails 3, 3. On the hallway 30 side of each set are door pockets 32, 32, . . . for accommodating the unit pieces 31, 31, . A pin 33 is attached to the partition wall 31, and the pin is attached to the rail 3 provided under the floor and the groove 34a of the lintel 34 on the ceiling side (see Fig. 11 above).
It fits into the inside and movably supports said 31. Therefore, this device has the effect of freely changing the size of the room or changing the number of rooms within the range of at least the width of the partition wall unit piece 31 or its multiple, so it is easy to change the size of the room or change the number of rooms. This is extremely advantageous when you want to change the number of rooms depending on the situation, or when you want to change the entire room into one room when a large number of people gather, such as for a memorial service. Each unit piece 31 of the partition wall is preferably made of a lightweight wall material such as hard urethane covered with cloth. Note that the unit pieces 31 of each partition wall can be connected in an accordion style if desired.
In addition, a dedicated threshold rail may be installed separately in place of the existing rail.

Although the basic configuration of the present invention and some of its application examples have been explained above, these are just a few examples and do not convey the entire picture. For example, the examples explained above naturally apply to the fixtures and equipment of offices, shops, etc. For example, rearranging sales floors in department stores is a very hard labor that is frequently performed, but according to the means of the present invention, even large display shelves and show cases can be moved easily and easily. Moreover, there is no possibility of damage to the flooring due to forcibly dragging heavy objects, so the installation of this device in these locations is also useful in improving working conditions. Furthermore, the combination of a wheeled leg plate and a rail according to the invention can of course be replaced by a combination of a sliding leg plate and a roller or a rolling ball as an equalizer. These uniform methods are inferior to the former in terms of running smoothness, but have greater load bearing capacity than wheels. FIG. 13 shows an example in which the sliding plate 36 attached to the lower end of the leg plate 7 is placed on the lower rolling ball 37 in the example of FIG. 2 above. It is preferable that the balls 37 are arranged as densely as possible. Note that instead of the pair of balls, rollers with a length spanning the track can also be used, but in this case, it is desirable to add a guide to regulate the sliding direction of the leg plate 7.
