Description

[Technical field]

[0001] This invention relates to a children's building block sofa made up of multiple cushion blocks of different shapes. [Background technology]

[0002] 2. Description of the Related Art Conventionally, as a small sofa for children, for example, a kids sofa described in Non-Patent Document 1 and the like are known. This kids sofa has a seat of a suitable size for a child to sit on, a backrest connected to the rear end of the seat to support the child's back, a pair of armrests connected to the left and right ends of the seat, and four legs attached to the underside of the seat. All of these components had shapes according to their respective functions, and adjacent parts were connected to each other. [Prior art documents] [Patent documents]

[0003] [Non-Patent Document 1] [Retrieved December 22, 2024], Internet<URL;https: / / store.shopping.yahoo.co.jp / taiho-kagu2 / 3720071000.html> Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional kids' sofas, all of the components, such as the seat and backrest, have shapes according to their respective functions, and adjacent parts are connected to each other. Therefore, the shape of the sofa is always the same, and it is not possible to freely change the shape of the sofa to suit a child's imagination while playing.

[0005] As a result of extensive research, the inventor discovered that by using a number of cushion blocks, each of which does not have a specific function such as a seat or a backrest and which differ from one another in shape, as components of a children's sofa, children can safely play with these cushion blocks by freely stacking, arranging and knocking them down as if they were large building blocks, thereby stimulating children's five senses while improving their creativity, concentration, thinking ability, spatial awareness, etc., and thus completed the present invention.

[0006] The present invention has been made in consideration of the conventional problems, and aims to provide a building block sofa that allows children to safely play with large building blocks using a number of cushion blocks of different shapes, thereby stimulating the child's five senses and enhancing their creativity, concentration, thinking ability, spatial awareness, etc. [Means for solving the problem]

[0007] The invention described in claim 1 is a building block sofa characterized by being constructed by combining multiple cushion blocks of different shapes as building block parts that can be separated from each other.

[0008] The type of sofa is not limited, and may be, for example, a one-seater or a two-seater or more. The cushion blocks referred to here do not have shapes corresponding to the functions of the seat and backrest as components of a sofa. Adjacent parts are detachable from each other. (For example, they may be fastened by hook-and-loop fasteners, magnets (including sheet-like ones), etc.) The type of cushion block is not limited, and may be, for example, a cushion block having a filling material such as foamed plastic (urethane foam, etc.) or batting covered with a bag-shaped cushion cover made of fabric or leather. The number of cushion blocks of each type used is also arbitrary. For example, one or two of each type may be used.

[0009] Each cushion block may have any shape. The size of each cushion block is much larger than a typical palm-sized building block, and the weight of each cushion block is arbitrary (for example, 100 g to 1 kg) as long as the child can handle it.

[0010] The invention described in claim 2 is the block sofa described in claim 1, characterized in that the plurality of cushion blocks include a square plate block, a circular plate block, a trapezoidal plate block, a semicircular plate block, an arch block, a rectangular pillar block, and a trapezoidal pillar block, each of which can be washed.

[0011] The invention described in claim 3 is a building block sofa described in claim 1 or claim 2, characterized in that each of the multiple cushion blocks is a foamed plastic body having a hardness of 120N to 200N covered with a bag-shaped cushion cover.

[0012] If the hardness of the foam plastic body is less than 120N, the cushion block is too soft and cannot support the weight of a child when used as a sofa, and if the hardness exceeds 200N, the cushion block is too hard and uncomfortable to sit on when used as a sofa. The recovery rate of the foamed plastic body should be 95% or more. If it is lower than this, the cushion block will easily become sagging. Effect of the Invention

[0013] The sofa of this invention uses multiple cushion blocks as components for the children's sofa, each of which does not have a specific function such as a seat or a backrest and has a different shape, so children can safely play with these cushion blocks by freely stacking, arranging, and knocking them down as if they were large building blocks. As a result, while ensuring safety during use, it is possible to enhance a child's creativity, concentration, thinking ability, spatial awareness, etc., while stimulating the child's five senses.

[0014] In particular, according to the present invention described in claim 2, seven different shaped blocks, namely, square plate blocks, circular plate blocks, trapezoidal plate blocks, semicircular plate blocks, arch blocks, rectangular pillar blocks and trapezoidal pillar blocks, are adopted as the cushion blocks for the building block sofa, which further stimulates children's five senses and allows them to create objects of various shapes (e.g. cars, houses, etc.), thereby further enhancing children's imagination and development. In addition, each cushion block is fully washable, so that any dirty cushion block can be washed and cleaned at any time.

[0015] According to the present invention described in claim 3, each cushion block is made of a foamed plastic body having a hardness of 120N to 200N covered with a bag-shaped cushion cover, so that a sofa assembled from the cushion blocks has a good feel as a sofa and is soft to the touch when a child plays with it as a building block. In addition, even if a child hits the cushion block hard or slams it against a wall, parts of the plastic body will not be torn off. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] An embodiment of this invention will now be described in detail. EXAMPLES

[0018] As shown in Figures 1 and 2, the building block sofa 10 according to the first embodiment of the present invention is made up of seven types of cushion blocks C, each of which is fully washable: (1) two square plate blocks 11, (2) four circular plate blocks 12, (3) two trapezoidal plate blocks 13, (4) two semicircular plate blocks 14, (5) two arched plate blocks 15, (6) two rectangular pillar blocks 16, and (7) two trapezoidal pillar blocks 17. These cushion blocks C are assembled adjacent to each other in a separable manner as building block parts.

[0019] Each cushion block C is made of a urethane foam (foamed plastic body) 29 having a hardness of 150N and a recovery rate of 98.5%, covered with a cushion cover 30 made of a polyester bag. The sizes of each cushion block C are as follows: (1) The square plate block 11 is 70 cm long and wide and 70 cm high; (2) the circular plate block 12 is 30 cm in diameter and 12 cm high; (3) the trapezoidal plate block 13 is 10 cm in diameter and 60 cm high at the top, 70 cm in height and 12 cm thick; (4) the semicircular plate block 14 is 25 cm in radius and 12 cm thick; (5) the arch plate block 15 is 70 cm wide, 35 cm high, with an arch radius of 25 cm, 10 cm wide at the base of both legs and 12 cm thick; (6) the rectangular pillar block 16 is 12 cm wide and 70 cm high; and (7) the trapezoidal pillar block 17 is 13 cm in diameter and 30 cm high at the top, and 60 cm high. The total weight of the cushion block C is 10 kg.

[0020] Next, a method of using the block sofa 10 according to the first embodiment of the present invention will be described with reference to Figs. As shown in Fig. 1, when a child assembles a two-seater building block sofa 10 using cushion blocks C as building block parts, first, two trapezoidal plate blocks 13 with their upside-down orientations reversed are joined together in a square shape in plan view with their inclined surfaces in contact with each other, to obtain a first assembled square plate block 20 having the same shape as the square plate block 11. Then, the square plate block 11 is placed on top of the top surface of this first assembled square plate block 20.

[0021] On the other hand, to the right of a pair of trapezoidal plate blocks 13 assembled in a square shape in plan view, two arch plate blocks 15, each having a corresponding semicircular plate block 14 fitted into the inner space, are joined together in a square shape in plan view with their bottom surfaces in contact with each other, to obtain a second assembled square plate block 21 having the same shape as the square plate block 11. Then, the square plate block 11 is placed on top of the upper surface of this second assembled square plate block 21.

[0022] Next, a trapezoidal pillar block 17 is placed on the outer portion of the upper surface of each square plate block 11 as an armrest, while a pair of long rectangular pillar blocks 16 are placed on the left and right sides of the rear end of the upper surface of each square plate block 11 as a low backrest. Furthermore, a pair of left and right disk blocks 12 are leaned diagonally against the ends of the butt joints of each of the square pillar blocks 16, and another pair of left and right disk blocks 12 are placed as ottomans on the floor in front of the block sofa 10, thereby assembling the block sofa 10.

[0023] Next, as shown in FIG. 3, a method for a child to assemble a racing car (block sofa) 10A using cushion blocks C as building block parts will be described. First, two square plate blocks 11 are joined together in a butted state in the front-to-rear direction, and a trapezoidal pillar block 17 is laid on its side and placed with its length oriented in the left-to-right direction on the front end of the top surface of the front square plate block 11. An arch plate block 15 with its arch side facing backward is abutted against the rear end of the top surface of the front square plate block 11, and a pair of left and right disk blocks 12 are placed in a tire shape in the middle of the lengthwise left and right side edges.

[0024] Meanwhile, a pair of rectangular pillar blocks 16, each with its length oriented forward and backward, are placed on the left and right side edges of the rear square plate block 11, and a semicircular plate block 14 is placed on the top surface of each rectangular pillar block 16 from its rear end to near the center in the length direction. Furthermore, the other arch plate block 15 is placed on the rear part of the top surface of the rear square plate block 11, and a horizontally long trapezoidal pillar block 17 is placed on the rear part of the top surface of this arch plate block 15. Note that here, a trapezoidal plate block 13 is placed behind the rear 11. In this way, the racing car 10A is assembled using the cushion blocks C.

[0025] Next, as shown in FIG. 4, a method for a child to assemble a double bed (block sofa) 10B using cushion blocks C as building block parts will be described. First, the left and right side edges of the two square plate blocks 11 are butted against each other. Then, the rear edges of the square plate blocks 11 are butted against the rectangular pillar blocks 16, each with its length oriented in the left-right direction. The rear edge of the first assembled square plate block 20 is butted against the front edge of one of the square plate blocks 11, and the rear edge of the second assembled square plate block 21 is butted against the front edge of the other square plate block 11. Then, trapezoidal pillar blocks 17, each with its length oriented in the left-right direction, are placed in the front parts of the top surfaces of the first and second assembled square plate blocks 20 and 21, respectively, to assemble the double bed 10B using the cushion block C.

[0026] In this way, since a plurality of cushion blocks C, each of which does not have a specific function such as a seat or a backrest and has a different shape, are used as components of the building block sofa 10, children can safely play with these cushion blocks C by freely stacking, arranging, and collapsing them as if they were large building blocks. As a result, while ensuring safety during use, it is possible to enhance a child's creativity, concentration, thinking ability, spatial awareness, etc., while stimulating the child's five senses.

[0027] In addition, seven different shaped blocks, namely, a square plate block 11, a circular plate block 12, a trapezoid plate block 13, a semicircular plate block 14, an arch plate block 15, a rectangular pillar block 16 and a trapezoid pillar block 17, are used as the cushion blocks C of the building block sofa 10. This further stimulates the child's five senses and allows the child to create objects of various shapes (for example, cars, houses, etc.), thereby further enhancing the child's imagination and imagination. In addition, each cushion block is fully washable, so that any dirty cushion block can be washed and cleaned at any time.

[0028] Furthermore, since each cushion block C is made of urethane foam 29 having a hardness of 150N covered with a bag-shaped cushion cover 30, the building block sofa 10 assembled with the cushion blocks C has a good usability as a sofa, feels good to the touch when a child plays with it as a building block, and even if a child hits the cushion block C hard or slams it against a wall, parts of the urethane foam 29 will not break off. [Industrial Applicability]
