Description

[Technical field]

[0001] This invention relates to a kids desk that can be used as a child grows. [Background technology]

[0002] Among study desks, desks (kids desks) whose tabletop height can be adjusted to suit the growth of children from infants to elementary school students are known, as described in Non-Patent Document 1, for example.

[0003] This height-adjustable study desk comprises a pair of left and right legs having front and rear support legs each having multiple rows of mounting holes formed at a predetermined pitch in the vertical direction, a top plate having a pair of side panels at both left and right ends, and a reinforcing plate mounted horizontally across the middle of each leg.

[0004] [Non-Patent Document 1] [Searched on January 23, 2020], Internet<URL:https: / / www.kagu-wakuwaku.com / products / detail / 1164> Summary of the Invention [Problem to be solved by the invention]

[0005] However, conventional height-adjustable desks had reinforcing plates installed horizontally between the middle sections (lower halves) of each leg, so the tabletop could not be lowered sufficiently to a height suitable for a child sitting in the chair when he or she was a small toddler.

[0006] Therefore, after extensive research, the inventor discovered that all of the above-mentioned problems could be solved if, when used by a short infant, the table top is placed between the lower parts of a pair of left and right legs, and a reinforcing plate connected between the lower halves of each leg can be hung between the upper parts of these legs as a shelf, while when the child grows up and, for example, reaches elementary school age, the table top can be moved to the top of each leg and this reinforcing plate can be hung between the lower halves of each leg in its original position, thereby completing the present invention.

[0007] The present invention has been developed in consideration of such conventional problems, and aims to provide a kids' desk in which the height of the tabletop can be adjusted as the child grows, and in which a reinforcing plate mounted horizontally between the lower halves of a pair of left and right legs can be moved between the upper parts of each leg and used as a shelf when the child is young. [Means for solving the problem]

[0008] The invention described in claim 1 is a kids' desk having a height-adjustable top plate attached to a pair of left and right legs, characterized in that a reinforcing plate that can be used as a shelf is horizontally installed between the lower halves of each leg and between the upper parts of each leg when the top plate is attached to the lower parts of the legs.

[0009] The size of the kids' desk is arbitrary. For example, it may be 50cm to 1m in height, 50cm to 1m in width, and 30cm to 80cm in depth. The components of the kids' desk (e.g., the legs having the front and rear support legs, the top plate, etc.) can be made of any material. For example, various types of wood, various types of plastic, various types of metal, etc. can be used.

[0010] The size of the tabletop is arbitrary. For example, the width may be 50 cm to 1 m, and the depth may be 30 cm to 80 cm. The tabletop includes those having drawers of various structures.

[0011] The material of the reinforcing plate is arbitrary, for example, various wood materials, various plastic materials, various metal materials, etc. The size and number of reinforcing plates used are also arbitrary. The top plate and the reinforcing plate may be detachably connected to the pair of left and right legs by any structure, for example, by screws or hooks.

[0012] The invention described in claim 2 is the kids' desk described in claim 1, characterized in that a pair of left and right side panels are arranged on both left and right ends of the tabletop, each of which has a front end that is lower in height than its rear end, and the tabletop is attached to the pair of left and right legs via these side panels, with the front ends of each side panel protruding forward.

[0013] The "shape in which the height of the front end is lower than the height of the rear end" may be, for example, a trapezoid or a shape similar thereto. The difference in height between the front end and the rear end of each side panel is arbitrary, and may be, for example, 1 cm to 10 cm. The length by which the front end of each side plate protrudes forward beyond each front support leg is arbitrary, and may be, for example, 1 cm to 20 cm.

[0014] The invention described in claim 3 is the kids' desk described in claim 2, characterized in that the pair of left and right legs are provided with front and rear support legs, each of which has multiple rows of mounting holes formed at a predetermined pitch in the vertical direction, and each of the front support legs, including the vertical arrangement of the corresponding mounting holes, gradually inclines forward as it goes downward, and the front and rear ends of each side panel are provided with a plurality of separate mounting holes arranged in pairs that can respectively communicate with the mounting holes of the corresponding rows of the front support legs and the rear support legs, and of the pair of separate mounting holes, the one on the front end side of the side panel is a long hole extending in the front-to-rear direction, and the top panel is screwed to the pair of left and right legs in a height-adjustable manner via the multiple separate mounting holes including the long holes and the mounting holes that overlap these separate mounting holes.

[0015] The number of mounting holes in the multiple rows drilled in each of the front and rear legs may be any number greater than or equal to 2. For example, the number may be 10 to 15. The pitch at which the mounting holes are formed can also be arbitrary, for example, 2 cm to 5 cm apart. The downward forward inclination angle of each front support leg, including the vertical arrangement of each mounting hole, is arbitrary, and may be, for example, 3° to 30°.

[0016] The length of the slot formed in the front end of each side panel is arbitrary, and may be, for example, 5 cm to 30 cm. The number of separate mounting holes arranged in pairs at the front and rear ends of each side plate is arbitrary. For example, there may be one pair, or two or more pairs, one above the other. Effect of the Invention

[0017] In the kids' desk of this invention, when the child is a small child, the tabletop is attached to the lower part of the pair of legs on the left and right, and the reinforcing plate disposed between the lower halves of each leg is placed horizontally between the upper parts of these legs as a shelf board on which books, small items, etc. can be placed. Later, when the child grows up to be an elementary school student, the table top is moved to the top of each leg, and the reinforcing plates that served as shelves are removed from between the upper parts of each leg and returned to the lower halves of each leg (mounted horizontally). This allows the height of the tabletop to be adjusted as the child grows, and the reinforcing plate stretched horizontally between the lower halves of the pair of left and right legs can be moved to between the upper parts of the legs and used as a shelf when the child is young.

[0018] In particular, according to the present invention as described in claim 2, the pair of left and right side panels have a shape in which the height of the front end is lower than the height of the rear end, and the front end of each side panel protrudes forward beyond the front support legs of the corresponding legs. This increases the attachment strength of the tabletop to the left and right legs, and when a child stands up or sits down from a chair placed in front of the desk, the child's feet are less likely to hit the front ends of the pair of left and right side panels that protrude forward beyond the front support legs.

[0019] Furthermore, according to the present invention as described in claim 3, the front support legs of the pair of left and right legs are designed to gradually slope forward as they go downward, including the upper and lower arrangements of the mounting holes. This makes it less likely that cracks will occur in the upper front part and lower rear part of each front support leg due to the short length from the corresponding edge of the front support leg to each mounting hole, a problem that was present in conventional desks.

[0020] That is, in the conventional desk, even though each front leg is gradually inclined forward toward the bottom, the length between the mounting holes arranged in multiple stages on the front and rear legs is the same. Therefore, at the upper part of each front leg, the length from the front edge of the front leg to the corresponding mounting hole is short, and there is a risk of cracks occurring in the front part of the upper part of each front leg during use. Similarly, at the lower part of each front leg, the length from the rear edge of the front leg to the corresponding mounting hole is short, and there is a risk of cracks occurring in the rear part of the lower part of the front leg during use. However, with the desk of the present invention, the occurrence of such cracks can be reduced for the reasons described above.

[0021] Furthermore, of the separate mounting holes arranged in pairs at the front and rear ends of each side panel, the separate mounting hole at the front end of each side panel is made a long hole extending in the front-to-rear direction.Therefore, even if the front support legs of the pair of left and right legs, including the upper and lower arrangement of each mounting hole, gradually incline forward as they go downward (the lengths between the mounting holes formed in multiple stages on each of the front and rear support legs vary for each stage), the top plate can be screwed to the pair of left and right legs so that the height can be adjusted as the child grows.

[Diagram 2] FIG. 2 is a side view of the kids' desk according to the first embodiment of the present invention when used by a child. [Diagram 3] FIG. 2 is an overall perspective view of the kids' desk according to the first embodiment of the present invention when used by an elementary school student. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The following is a detailed description of the embodiments of the present invention. EXAMPLES

[0024] As shown in Figures 1 and 2, the kids' desk 10 of Example 1 of the present invention has a pair of left and right legs 11 having front support legs 17 and rear support legs 18 each having 12 rows of mounting holes 16 formed therein at 3 cm intervals downward, and a top plate 13 with a pair of side panels 15 arranged on both left and right ends.

[0025] These components will now be described in detail. As shown in Figures 1 and 2, the size of the kids' desk 10 is 72 cm in height, 80 cm in width, and 42 cm in depth. The top plate 13 is made of rubberwood (natural wood) in a horizontally long rectangular shape, and a protruding frame 25 is provided on the rear edge (the other plate materials are also made of rubberwood). Further, near the protruding frame 25 of the top plate 13, a horizontal groove 26 for supporting a tablet used as a teaching material and a pen holder 27 are arranged in a row. A drawer 24 is provided below the top plate 13.

[0026] The upper ends of the front support legs 17 and the rear support legs 18 are connected by an upper connecting plate 21 , and the lower ends of the front support legs 17 and the rear support legs 18 are connected by a lower connecting plate 22 . In addition, each front support leg 17, including the vertical arrangement of the corresponding mounting holes 16, is gradually inclined forward as it goes downward.

[0027] The pair of left and right side panels 15 are roughly cloud-shaped with the height of the front end connected to the front support leg 17 being 3 to 5 cm lower than the height of the rear end connected to the rear support leg 18, and the front end of each side panel 15 protrudes forward beyond the front support leg 17 of the corresponding leg 11. A long hole (another mounting hole) 19 extending in the front-rear direction is formed at the front end of each side plate 15 and can respectively communicate with the mounting hole 16 of the corresponding stage of each front support leg 17. In addition, a separate mounting hole 20 is formed at the rear end of each side plate 15 and can respectively communicate with the mounting hole 16 of the corresponding stage of each rear support leg 18.

[0028] The top plate 13 is fixed to the pair of left and right legs 11 via separate mounting holes 20 including the long holes 19 and the overlapping mounting holes 16 with screws 30 so that the height can be adjusted. A shelf plate (reinforcing plate) 14A is horizontally installed between the rear upper ends of the legs 11 via screws 30. This shelf plate 14A can be used as the reinforcing plate 14 between the lower parts of the rear support legs 18.

[0029] Next, a method of using the kids' desk 10 according to the first embodiment of the present invention will be described with reference to Figs. First, as shown in Figures 1 and 2, when the child is an infant (when using a low desk), the top plate 13 is provided on the lower part of a pair of left and right legs 11 that are 47 cm high from the floor, and the reinforcing plate 14 that was provided between the lower part of each leg 11 is horizontally placed as a shelf plate 14A between the rear upper ends of these legs 11. At this time, books, small items, etc. are placed on this shelf plate 14A.

[0030] As shown in Figures 2 and 3, when a child grows to be an elementary school student or the like (when using the desk as a high desk), the table top 13 is moved to the top of each leg 11 at a height of 72 cm from the floor, and the reinforcing plate 14, which served as a shelf 14A, is removed from between the rear upper ends of each leg 11 and returned to the space between the lower parts of each rear support leg 18 (mounted horizontally). This allows the height of the top board 13 to be adjusted as the child grows, and the reinforcing board 14, which is laid horizontally between the lower halves of the pair of left and right legs 11, can be moved to between the upper parts of the legs 11 and used as a shelf board 14A when the child is young.

[0031] In this way, in Example 1, a pair of left and right side panels 15 are used that have a shape in which the height of their front ends is lower than the height of their rear ends, and the front ends of each side panel 15 protrude forward from the front supports 17 of the corresponding legs 11. This increases the attachment strength of the top panel 13 to the left and right legs 11, and when a child stands up or sits down from a chair placed in front of the kids desk 10, the child's feet are less likely to hit the front ends of the pair of left and right side panels 15 that protrude forward from each front support leg 17.

[0032] In addition, the front support legs 17 of the pair of left and right legs 11, including the upper and lower arrangement of the mounting holes 16, are gradually inclined forward as they go downward. This means that cracks, which were a problem with conventional desks, are less likely to occur in the upper front part and lower rear part of each front support leg due to the shortened length from the corresponding edge of the front support leg to each mounting hole.

[0033] That is, in the conventional desk, even though each front leg is gradually inclined forward toward the bottom, the length between the mounting holes arranged in multiple stages on the front and rear legs is the same. Therefore, at the upper part of each front leg, the length from the front edge of the front leg to the corresponding mounting hole is short, and there is a risk of cracks occurring in the front part of the upper part of each front leg during use. Similarly, at the lower part of each front leg, the length from the rear edge of the front leg to the corresponding mounting hole is short, and there is a risk of cracks occurring in the rear part of the lower part of the front leg during use. However, in the kids' desk 10 of the present invention, the occurrence of such cracks can be reduced for the reasons described above.

[0034] Furthermore, of the other mounting holes arranged in pairs at the front and rear ends of each side panel 15, the other mounting hole on the front end side of each side panel 15 is made to be a long hole 19 extending in the front-to-rear direction. Therefore, even if the front support legs 17 of the pair of left and right legs 11, including the vertical arrangement of each mounting hole 16, gradually incline forward as they go downward (the lengths between the mounting holes 16 formed in multiple stages on each of the front and rear support legs 17, 18 vary for each stage), the top panel 13 can be screwed to the pair of left and right legs 11 in a height-adjustable manner as the child grows. [Industrial Applicability]

[0035] This idea is useful as a kids' desk technique that can be used as the child grows. [Explanation of symbols]
