Description

  The present invention relates to a loft bed that can be easily assembled.

  A loft bed is also called a high bed. The bed is located higher than the floor, with a ladder and stairs for climbing the bed, and underneath it is a space for a study desk, sofa, hanger, etc. Say. Because it can efficiently use a small space, it can be used for children's rooms and single-room apartments and apartments where people can live alone. Loft means “attic” or “mezzanine”, and the loft bed is also called “system bed”.

  Since this loft bed is used in a one-room apartment or the like, it is desired that the loft bed be brought into the room as a set and be light weight that can be assembled even by an unfamiliar person or woman.

The following documents can be found as prior art relating to loft beds.

  Each of the above prior arts relates to a loft bed. However, Patent Document 1 prevents cotton dust descending downward, and Patent Document 2 can be converted into two forms of a baby bed and a loft bed. Further, Patent Document 3 is an invention of a bed unit in which a book shelf unit and a clothing shelf unit are placed on the leg of the bed unit and the strength against rolling is increased. Patent Document 4 relates to a system bed that can be removed from a plate-shaped support material and a box-shaped support material and can be brought into contact with the floor to form a relatively low bed. Patent Document 5 can be assembled. Although it is related to the configured system bed, it seems that it takes time to assemble it.

  Therefore, the present application provides a loft bed that has a relatively simple structure and can be easily assembled even in a studio apartment.

  That is, in the first invention, four pillars are vertically connected to form a rectangle, a plate is attached to all or a part of the upper rectangle, and a tenon is fixed vertically to the upper surface of the plate surface. A mortise-supporting column is placed on a four-tenon support column with a tenon with a tenon through-hole in the four corners. This is a loft bed for assembly, in which a fall-preventing frame provided with tenon through holes at four corners is passed through the tenon of the supporting column with tenon and placed around the bed on the bed.

The cross section of the column may be circular or rectangular, and may be circular or rectangular. The four pillars have the same length, and the four pillars are connected by a cross or the like so that the cross section becomes rectangular. A plate is attached to all or a part of the upper rectangle. The plate is a surface that is horizontal with respect to the floor surface and is used to stand the tenon vertically upward, and serves as a part that supports a bed, a fall prevention frame, and a weight of a user to be described later. A tenon is fixed to the plate vertically and fixed vertically. A tenon is a protrusion created at the end of one member to join two members such as wood and metal. The four legs of the loft bed with the tenon shall be the support pillar with the tenon. The upper direction means the direction toward the ceiling.
The mortise must be securely fixed to the plate. If the tenon is loose or falls off the plate, it may cause a serious accident such as injury to the user.

The four mortise-supporting pillars are vertically set at predetermined positions, and the mortises of the support mortise-bearing pillars (hereinafter sometimes referred to as mortises) are passed through the tenon holes of the bed provided with tenon-passage holes at the four corners. Let the bed rest on the four mortise support pillars, and the four mortise support pillars are fixed. Here, the bed means a rectangular flat plate having an appropriate size for a person to sleep. Tenon through holes are provided at the four corners of the bed, and vent holes are appropriately formed in the center.
The four corners are a bed, a fall prevention frame, which will be described later, and a wooden decorative frame, which are rectangular, and a place close to a right angle portion inside the rectangle.

First, four mortise-supporting pillars are set up on the floor to an appropriate size. A berth is placed on the mortise, and the support columns with mortises are moved to pass through the tenon holes of the berth, so that the positions of the support columns with mortises are fixed.

Next, let the tenon of the support column with mortise protruding from the tenon through hole at the four corners of the bed go through the tenon hole of the anti-fall frame with the tenon through holes at the four corners, and put the fall prevention frame into the bed Put it on top and make it a loft bed for assembly. The fall prevention frame is a frame that surrounds the periphery of the bed so that a person does not fall from the bed, and has a predetermined height.

  The tenon holes of the fall prevention frame can be provided with plates attached to the upper and lower four corners of the fall prevention frame (in this case, there are 8 places to attach the plate), and tenon holes can be provided there. The tenon which penetrates the tenon hole of the bed may be a structure which can penetrate further.

Subsequently, in the second invention, the three pillars are vertically connected to form a right triangle, a plate is attached to all or a part of the upper right triangle, and the tenon is perpendicular to the upper surface of the plate surface. Fix the support column with mortises, and place a bed with mortise through holes at the four corners on the support columns with mortises through the tenon of the support columns with mortises. This is a loft bed for assembly in which a fall prevention frame provided with tenon through holes at the four corners is passed through the tenon of the support pillar with tenon and placed around the bed on the bed.

In the first invention, four columns are connected to a rectangle to form a support column with a tenon. In the second invention, three columns are connected to each other so that the cross section is a right triangle. Etc., and a plate is attached to all or a part of the upper right triangle, and a tenon is fixed vertically to the plate, and this is used as a support column with a tenon.
Although it is difficult to stand upright with only one pillar, it is possible to stand upright independently by connecting four pillars to a rectangle or three pillars to a right triangle. The right triangle is used for the bed, and the fall prevention frame has right angles at the four corners so that it can be matched.

  The assembling method is the same as the tenon support column with four columns connected in a rectangular shape according to the first invention, and the tenon of the tenon support column with three columns connected in a right triangle is passed through the tenon through hole of the bed. Then, the loft bed is assembled by passing through the mortise hole of the fall prevention frame. The bed and the fall prevention frame are the same as in the first invention.

  Subsequently, the third invention attaches a plate to the upper cross section of the cylindrical column, fixes the tenon vertically to the upper surface of the plate surface, and forms a support column with tenon, on the four tenon support columns. Place a bed with tenon through holes on the four corners through the tenon of the support column with tenon, fix the position of the four support columns with tenon, and then place tenon holes at the four corners on the bed. This is an assembly loft bed in which a fall prevention frame provided is passed through a tenon of a support column with a tenon and placed around a bed.

In the first and second inventions, four or three columns are prepared, a plate is attached, and a tenon is fixed to the plate vertically to form a supporting column with a tenon. In the third invention, a cylinder is used. A plate is attached to the upper cross section of a single pillar, and a tenon is fixed vertically to the upper surface of the plate surface to form a support pillar with a tenon.

Not only metal pipes but also wooden pipes and plastic pipes are commercially available. It is cylindrical and the inside is hollow, and it is sufficient if it is cylindrical regardless of circular or rectangular. The cylindrical shape is used to reduce weight and allow women to assemble.
A tenon with a tenon fixed vertically on a horizontal plate is used as a support column with a tenon. In the sense of organization, the support column with tenon using the four columns of the first invention is used as a support column with a rectangular tenon. The support column with tenon using the three columns of the second invention is a support column with right tenon, and the support column with the tenon of the third column of the third invention is a support column with a single tenon.

Although it is difficult to stand alone with the support column with a single tenon according to the third invention, the bed is leaned substantially perpendicular to the floor, and in that state, the tenon of the support column with the single tenon is passed through the tenon through hole of the bed, After that, the loft bed can be assembled by raising the four support columns with tenons. The bed and the fall prevention frame are the same as in the first invention.
In addition, it is also possible to use a rod-like column as a support column with a single tenon instead of a hollow cylinder.

  A fourth invention is the loft bed for assembly according to any one of the first to third inventions, in which the tenon support column and the fall prevention frame are made of metal and the bed is made of wood.

  Even if it is made of wood or plastic, the strength of the loft bed may be maintained. However, the reason why the support column with mortise and the fall prevention frame are made of metal is to ensure safety. In the loft bed, the sleeping position is 1 m or more higher than the floor surface, and earthquake resistance is also required, and it is limited to metal. It is made of metal and may be made of lighter aluminum as well as iron. The fall prevention frame is also made of metal for the same purpose.

  According to a fifth aspect of the present invention, there is provided a wooden decorative frame provided with tenon holes at four corners, and a tenon projecting through the tenon hole of the fall prevention frame on the fall prevention frame is provided with the tenon hole of the wooden decorative frame. It is a loft bed for assembly according to any one of the first to fourth inventions with a wooden decorative frame attached through.

  The wooden decorative frame is placed on the fall prevention frame for the sake of touch and appearance. When you get up or lie down, you often grab the fall prevention frame. If the fall prevention frame is made of metal, it feels cold in winter. In addition, the wooden decorative frame can be patterned to moisturize the room. Therefore, a wooden decorative frame is placed on the fall prevention frame.

  A sixth aspect of the invention is the assembly loft bed according to any one of the first to fifth aspects of the invention, wherein the elevating ladder is attached to the fall prevention frame.

  In the support column with a rectangular mortise and the support column with a right mortise, four or three columns are connected by a cross or the like. The crossbar can be used as a ladder for raising and lowering the loft bed. However, it may be difficult to move up and down due to the vertical. In addition, since the support column with a single tenon has no ladder for raising and lowering, a ladder for raising and lowering is prepared.

The first invention, the second invention, and the third invention provide a loft bed that is easy to assemble by placing a bed with a tenon through hole on a support column with a tenon and a fall prevention frame.
The 4th invention improves safety, such as earthquake resistance, and the 5th invention and the 6th invention improve the convenience of the user of a loft bed, respectively.
