Description

[Technical field]

[0001] The present disclosure relates to a blanket and table set. [Background technology]

[0002] Various types of hangers for kotatsu have been proposed (see Patent Document 1), for example, hangers with an opening formed in the center have been proposed (see Patent Documents 2 to 4).

[0003] Similar hanging devices can also be used in combination with tables used for purposes other than kotatsu, for example, it is possible to use the hanging devices in combination with tables used for outdoor purposes (see Patent Document 5). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 58-187367 [Patent Document 2] Registered Utility Model No. 3041304 [Patent Document 3] Japanese Patent Application Publication No. 1-260222 [Patent Document 4] JP 2006-150022 A [Patent Document 5] JP 2019-136180 A Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned conventional hanging devices are used by being placed on the top of a table, so the position of the hanging device relative to the table is easily shifted. For example, when a user enters or exits the space inside the hanging device placed on the table, the user may unintentionally pull the hanging device, causing the hanging device to shift position, and cold outside air may flow into the space inside the hanging device.

[0006] As lifestyles become more diverse, it is becoming common for households to not have kotatsu, and various types of tables are being used in each household. There is a demand for combining blankets with such various types of tables and using them like kotatsu. Thus, there is a demand for a blanket that can be used not only for kotatsu but also for various other types of tables, and that is highly convenient.

[0007] The present disclosure has been made in consideration of the above-mentioned circumstances, and aims to provide a blanket that is advantageous in preventing misalignment relative to a table when used in combination with a table, and a table set that utilizes such a blanket. [Means for solving the problem]

[0008] One aspect of the present disclosure relates to a blanket that can be attached to a table, the blanket comprising: a main body having an opening peripheral edge that defines an opening; a band- or string-shaped first extension member provided at the opening peripheral edge and extending circumferentially about the opening, the first extension member being capable of locally changing the circumferential size of the opening peripheral edge in a width direction perpendicular to the circumferential direction; and a band- or string-shaped second extension member provided at the opening peripheral edge and extending circumferentially at a position farther from the opening than the first extension member, the second extension member being capable of locally changing the circumferential size of the opening peripheral edge in the width direction.

[0009] At least one of the first extension member and the second extension member may be an elastic member that is elastically expandable and contractible.

[0010] The blanket may include a band- or string-shaped stopper extension member provided at the peripheral edge of the opening, extending circumferentially at a position farther from the opening than the second extension member, and having a smaller elasticity than the first extension member and the second extension member.

[0011] The blanket may include one or more additional extension members in the form of bands or strings provided at the peripheral edge of the opening and extending circumferentially at a position farther from the opening than the second extension member, and which can locally change the circumferential size of the peripheral edge of the opening in the width direction.

[0012] The spacing between the first extension member and the second extension member may be different from the spacing between the second extension member and an additional extension member adjacent to the second extension member.

[0013] The body may have gathers.

[0014] The blanket may include a locking portion that can be locked to the table.

[0015] Another aspect of the present disclosure relates to a table set comprising a table and the blanket described above, the blanket being attached to the table with an open peripheral edge surrounding the table. Effect of the Invention

[0016] According to the present disclosure, it is possible to provide a blanket that is advantageous in preventing misalignment relative to a table, and a table set that utilizes such a blanket. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a perspective view showing an example of a table set in which the blanket shown in FIG. 1 is attached to a table. [Diagram 3] FIG. 3 is a partial enlarged view showing an example of an opening peripheral end portion of a blanket. [Figure 4] FIG. 4 is a diagram for explaining the amount of deflection of the extension member. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0019] In the following description, terms indicating directions such as "upper" and "lower" are merely expedient expressions based on a state in which the blanket is attached to a table based on standard usage, unless otherwise specified. Therefore, such terms indicating directions do not limit the orientation of each element in this disclosure, and the actual blanket and table may be oriented in any direction depending on the usage state.

[0020] Fig. 1 is an external view showing an example of a blanket 10. Fig. 2 is a perspective view showing an example of a table set 15 in which the blanket 10 shown in Fig. 1 is attached to a table 11.

[0021] The blanket 10 shown in Fig. 1 is a blanket that can be attached to a table 11 (see Fig. 2), and includes a main body 20 made of a flexible material, typically made of cloth. There are no limitations on the cloth that can be used to make the main body 20. The main body 20 can be made of at least one of natural fibers and synthetic fibers, and may be a woven fabric or a fabric other than a woven fabric (e.g., a nonwoven fabric).

[0022] The main body 20 has an integrally formed opening peripheral edge 21 and a hem portion 22. The opening peripheral edge 21 and the hem portion 22 are made of the same material in the example shown in Fig. 1, but may be made of different materials.

[0023] The opening peripheral edge 21 is a portion that defines the opening (through hole) 30 located in the center of the main body 20, and forms the upper edge of the main body 20. The hem 22 is a portion that extends downward from the opening peripheral edge 21, and forms the lower edge of the main body 20.

[0024] When the blanket 10 is attached to the table 11, the table 11 is placed at a position corresponding to the opening 30 of the blanket 10, and the peripheral edge 21 of the opening of the blanket 10 is supported by the table 11 while horizontally surrounding the table 11. In this manner, the blanket 10 is attached to the table 11 via the peripheral edge 21 of the opening, and the space below the top plate portion of the table 11 is surrounded by the hem 22 of the blanket 10.

[0025] The main body 20 of the blanket 10 has gathers 25, also called wrinkles or folds, at each of the opening peripheral edge 21 and the hem 22, and has an undulating uneven shape along the circumferential direction Dc of the opening 30.

[0026] In the example shown in Fig. 2, a top plate portion (particularly an outer peripheral end portion) provided to protrude horizontally from a plurality of (e.g., four) legs of the table 11 supports an opening peripheral end portion 21 surrounding the top plate portion, thereby attaching the blanket 10 to the table 11. The opening peripheral end portion 21, which can be flexibly deformed, can partition the opening 30 into any planar shape, and therefore can be appropriately attached to a top plate portion other than the example shown in Fig. 2. That is, although the top plate portion shown in Fig. 2 has a roughly rectangular planar shape, the opening peripheral end portion 21 of the blanket 10 can also be attached to a top plate portion having a planar shape other than a rectangle (for example, a polygonal planar shape other than a square, a circular (including an elliptical) planar shape, or an irregular planar shape).

[0027] FIG. 3 is a partial enlarged view showing an example of the open peripheral edge 21 of the blanket 10. As shown in FIG.

[0028] In the example shown in FIG. 3, a first extension member 31, a second extension member 32, a third extension member 33, and a fourth extension member 34 are provided at the opening peripheral edge 21 of the blanket 10.

[0029] Each of the first extension member 31, the second extension member 32, the third extension member 33, and the fourth extension member 34 is a band-like or string-like member extending in the circumferential direction Dc of the opening 30, and can locally change the circumferential size of the opening peripheral edge 21 in the width direction Dw perpendicular to the circumferential direction Dc. Each of the first extension member 31, the second extension member 32, the third extension member 33, and the fourth extension member 34 is assigned a specific end region (the first end region 21A, the third to fifth end regions 21C to 21E) of the opening peripheral edge 21, and extends in the assigned end region. Each of the first extension member 31, the second extension member 32, the third extension member 33, and the fourth extension member 34 can locally change the circumferential size of the assigned end region of the opening peripheral edge 21. For example, the circumferential size of the first end region 21A of the opening peripheral edge 21 is changed by the first extension member 31, the circumferential size of the third end region 21C is changed by the second extension member 32, the circumferential size of the fourth end region 21D is changed by the third extension member 33, and the circumferential size of the fifth end region 21E is changed by the fourth extension member 34. In this way, the circumferential size of the opening peripheral edge 21 can be partially (locally) changed and adjusted with respect to the width direction Dw of the opening peripheral edge 21.

[0030] Each of the first extension member 31, the second extension member 32, and the third extension member 33 shown in FIG. 3 is an elastic member that can be elastically stretched and contracted, and is made of a rubber cord such as a round rubber band (e.g., a bungee cord). On the other hand, the fourth extension member 34 shown in FIG. 3 is provided as a stopper extension member having a smaller stretch rate than the first extension member 31 to the third extension member 33, and is made of, for example, a fiber cord. In the example shown in FIG. 3, all of the extension members 31 to 34 have flexibility that allows them to bend, but the first extension member 31, the second extension member 32, and the third extension member 33 have greater rigidity and stretch rate than the fourth extension member 34, and an elastic force acts on them that tries to maintain a more linear shape than the fourth extension member 34 when no external force is applied.

[0031] The method by which each of the first extension member 31, the second extension member 32, the third extension member 33, and the fourth extension member 34 locally changes the circumferential size of the opening peripheral end 21 in the width direction Dw is not limited. As an example, a stopper device capable of changing the length of the portion of the extension member covered by the opening peripheral end 21 may be attached to each of the first extension member 31, the second extension member 32, the third extension member 33, and the fourth extension member 34. As an example, a stopper device (see reference numeral "26" in Figs. 1 and 2) having a size and shape that does not enter or is difficult to enter the inner space of the opening peripheral end 21 may be attached to the extension members 31 to 34 on the outside of the opening peripheral end 21. In this case, the stopper device 26 can variably determine the portion of the extension members 31 to 34 located outside the opening peripheral end 21 (and thus the portion located in the inner space of the opening peripheral end 21). Such a stopper device is a widely used known device, so a detailed structural example will not be described here.

[0032] 3 has a first end region 21A, a second end region 21B, a third end region 21C, a fourth end region 21D, and a fifth end region 21E arranged successively farther from the opening 30 (upper edge). These end regions 21A to 21E have inner spaces separated from one another.

[0033] The first extension member 31, the second extension member 32, the third extension member 33, and the fourth extension member 34 are disposed in the inner spaces of the first end region 21A and the third end region 21C to the fifth end region 21E of the opening peripheral end 21, respectively, and do not move to end regions other than the corresponding end regions. Therefore, the second extension member 32 extends in the circumferential direction Dc at a position farther from the opening 30 than the first extension member 31 (i.e., at a position closer to the hem portion 22 (see Figs. 1 and 2)). Similarly, the third extension member 33 extends in the circumferential direction Dc at a position farther from the opening 30 than the second extension member 32, and the fourth extension member 34 extends in the circumferential direction Dc at a position farther from the opening 30 than the third extension member 33.

[0034] In this way, the third extension member 33 and the fourth extension member 34 correspond to "one or more additional extension members" that are strip- or string-shaped and extend in the circumferential direction Dc at a position farther from the opening 30 than the second extension member 32, and include a stopper extension member (in this example, the fourth extension member 34) that has a smaller expansion rate than the first extension member 31 and the second extension member 32.

[0035] The size of the opening peripheral edge 21 in the width direction Dw (i.e., the direction from one of the upper edge portion and the lower edge portion of the main body 20 to the other) perpendicular to the circumferential direction Dc is not limited, and the size of the width direction Dw of the end regions 21A to 21E included in the opening peripheral edge 21 is also not limited. In the example shown in FIG. 3, the width direction size tb of the second end region 21B is larger than the width direction sizes of the other end regions 21A, 21C, and 21D. As a result, the distance in the width direction Dw between the first extension member 31 and the second extension member 32 is larger than the distance between the second extension member 32 and the third extension member 33 adjacent to the second extension member 32, and the distance between the third extension member 33 and the fourth extension member 34.

[0036] When the blanket 10 having the open peripheral edge 21 shown in Fig. 3 is attached to the top plate portion of the table 11, the first extension member 31 can be positioned above the top plate portion, while the second extension member 32, the third extension member 33, and / or the fourth extension member 34 can be positioned below the top plate portion. In this case, it is preferable that the first extension member 31 above the top plate portion is adjusted to have a smaller diameter than the top plate portion, while the second extension member 32, the third extension member 33, and / or the fourth extension member 34 located below the top plate portion are adjusted to have a smaller diameter than the top plate portion. As a result, not only the side surfaces of the outer peripheral edge of the table 11 but also the upper and lower surfaces are covered by the open peripheral edge 21, and it is possible to effectively prevent the blanket 10 from being misaligned with respect to the table 11 (particularly, misalignment in the width direction Dw).

[0037] When attaching blanket 10 (particularly opening peripheral edge 21) to the top plate portion of table 11 in this manner, changing which of second extension member 32, third extension member 33, and fourth extension member 34 is positioned below the top plate portion according to the thickness of the top plate portion is effective in preventing displacement of blanket 10 relative to table 11. For example, when the thickness of the top plate portion is smaller than width direction size tb (thickness T1) of second end region 21B of opening peripheral edge 21, second extension member 32, third extension member 33, and fourth extension member 34 can all be positioned below the top plate portion.

[0038] Furthermore, when the thickness of the top plate portion is larger than the width direction size tb of the second end region 21B but smaller than the width direction size (thickness T2=tb+tc) of the entire second end region 21B and third end region 21C, the third extension member 33 and the fourth extension member 34 can be positioned below the top plate portion. In this case, the second extension member 32 is disposed so as to fasten the side surface of the outer peripheral end portion of the top plate portion, thereby effectively contributing to preventing the blanket 10 from shifting in position relative to the table 11.

[0039] Furthermore, when the thickness of the top plate portion is greater than the widthwise size (thickness T2) of the entire second end region 21B and third end region 21C, but smaller than the widthwise size (thickness T3=tb+tc+td) of the entire second end region 21B, third end region 21C, and fourth end region 21D, the fourth extension member 34 can be positioned below the top plate portion. In this case, the second extension member 32 and the third extension member 33 are arranged so as to fasten the side surface of the outer peripheral end of the top plate portion, thereby effectively contributing to preventing the blanket 10 from shifting relative to the table 11.

[0040] The thickness of the top plate of the table in general circulation varies, but many tables have a top plate with a thickness of about 1 cm to about 5 cm. Therefore, the blanket 10 can show excellent versatility by having the opening peripheral edge 21 optimized for the top plate having a thickness of about 1 cm to about 5 cm. As an example, the width direction size tb of the second end region 21B of the opening peripheral edge 21 may be about 2 cm, while the width direction sizes tc and td of the third end region 21C and the fourth end region 21D may be about 1 cm. In this case, thanks to the elasticity in the width direction Dw inherent to the opening peripheral edge 21 and the play of the inner space of the end regions 21A, 21C to 21E with respect to the extension members 31 to 34, the opening peripheral edge 21 can be appropriately attached even to a top plate having a thickness somewhat larger than the width direction size (thickness T3) of the second end region 21B, the third end region 21C, and the fourth end region 21D as a whole.

[0041] Furthermore, even if the thickness of the top plate portion is greater than the widthwise size (thickness T3) of the entire second end region 21B, third end region 21C, and fourth end region 21D, blanket 10 can be attached to the outer circumferential end portion of table 11. In this case, blanket 10 can be appropriately attached to table 11 by arranging first extension member 31 and / or fourth extension member 34 in addition to second extension member 32 and third extension member 33 so as to tighten the side surface of the outer circumferential end portion of the top plate portion.

[0042] It should be noted that the portion of the table 11 to which the blanket 10 (particularly the opening peripheral edge 21) can be attached is not limited to the top plate portion. For example, the blanket 10 may be attached to the table 11 by having a plurality of legs of the table 11 surrounded and fastened by the opening peripheral edge 21. In particular, when each leg of the table 11 extends downward so as to gradually widen outward in the horizontal direction, attaching the opening peripheral edge 21 to such a plurality of legs effectively prevents the opening peripheral edge 21 (and thus the entire blanket 10) from shifting downward.

[0043] Even when the opening peripheral end 21 of the blanket 10 is attached to a part of the table 11 other than the top plate portion (e.g., the legs) in this manner, the blanket 10 can be properly attached to the table 11 by positioning at least one of the first extension member 31, the second extension member 32, the third extension member 33 and the fourth extension member 34 so as to tighten the part other than the top plate portion.

[0044] The main body 20 of the blanket 10 shown in Fig. 1 is provided with a locking portion 40 on the back side that can be locked to the table 11. The locking portion 40 shown in Fig. 1 is provided as a ring-shaped hook portion (e.g., flat rubber) having elasticity, and is hooked onto a holding portion (not shown) such as a protrusion provided on the table 11 (e.g., the back surface of the top plate). This makes it possible to effectively prevent the blanket 10 from shifting in position relative to the table 11. The locking portion 40 is not limited to the form shown in Fig. 1, and may be formed of a member that can be attached to a location other than the top plate (holding portion) of the table 11 (e.g., a string-like member that can be tied to the leg of the table 11), for example.

[0045] 4 is a diagram for explaining the amount of deflection of the extension member 35. The extension member 35 in FIG. 4 is representative of each of the above-mentioned first extension member 31 to fourth extension member 34, and the following description of the extension member 35 also applies to each of the first extension member 31 to fourth extension member 34.

[0046] 4, "L" represents the total length (horizontal length) of the linear extension member 35 when it is assumed that no external force (including gravity) is applied to the extension member 35. "m" and "n" represent the horizontal distance from each end of the extension member 35 to an arbitrary point X, and "f" represents the amount of deflection of the point X of the extension member 35. "X0" represents the center point of the extension member 35, and "f0" represents the amount of deflection of the center point X0 of the extension member 35.

[0047] If the mass per unit length of the extension member 35 is represented by "W" and the horizontal tension of the extension member 35 is represented by "H", the deflection f and f0 due to the weight (gravity) of the extension member 35 at point X and center point X0 can be expressed by the following equation.

[0048] f = W × m × n / (2 × H) f0=W×(L / 2)×(L / 2) / (2×H)=W×L 2 / (8×H)

[0049] Furthermore, if the magnitude of the concentrated load applied to a point on the extension member 35 is represented by "P", the amount of deflection f of the extension member 35 at point X when the concentrated load P acts on point X of the extension member 35 under the influence of gravity, and the amount of deflection f0 of the extension member 35 at the center point X0 when the concentrated load P acts on the center point X0 under the influence of gravity can be expressed by the following equations.

[0050] f = (1 / 2 × W × L + P) × m × n / (L × H) f0 = (1 / 2 × W × L + P) × L / (4 × H)

[0051] It is preferable to determine various conditions of the blanket 10 based on the above formula. For example, the "mass per unit length W" of the extension members 35 (each of the first to fourth extension members 31 to 34) and the "horizontal tension H of the extension members 35" may be appropriately determined by adopting a preset allowable deflection amount (upper limit deflection amount) as "f" ("f0") in the above formula, adopting the maximum side length of the table 11 assumed to be combined with the blanket 10 as "L" in the above formula, and adopting the expected concentrated load acting on the extension members 35 (particularly the expected maximum load) as "P" in the above formula.

[0052] For example, in the example shown in Figures 1 and 2, the horizontal tension H of the first extension member 31, the second extension member 32, and the third extension member 33 can be changed by adjusting the "portion located in the inner space of the opening peripheral end 21" of each of these extension members 31, 32, and 33 using the stopper device 26.

[0053] As described above, according to this embodiment, the first extension member 31 and the second extension member 32 are provided, which can locally change the circumferential size of the opening peripheral end 21 of the blanket 10 in the width direction Dw. This allows the blanket 10 (particularly the opening peripheral end 21) to be appropriately attached to the table 11 so as to effectively suppress misalignment of the blanket 10 with respect to the table 11.

[0054] Furthermore, the blanket 10 of this embodiment is widely applicable to tables 11 of various types and shapes, and can be used for tables with a low overall height (e.g., center tables), tables with a high overall height (e.g., dining tables), and tables with adjustable overall height (lift-up tables).

[0055] In addition, the blanket 10 of this embodiment can also be used in combination with a table 11 that is not a kotatsu, and by using a heated carpet in combination, the table 11 that is not a kotatsu can also be used like a kotatsu.

[0056] Furthermore, when the blanket 10 of this embodiment is attached to a kotatsu table having a frame and a top plate, there is no need to interpose the blanket 10 between the frame and the top plate. Therefore, it is possible to attach the blanket 10 to the kotatsu table while the frame and the top plate are fixed with fixing devices such as screws.

[0057] Furthermore, since the blanket 10 of this embodiment has the opening 30, it can be stored compactly while suppressing bulk. For example, it is possible to use the blanket 10 as a cushion by storing the blanket 10 in a cushion-shaped storage bag (not shown). Such a storage bag capable of storing the blanket 10 may be provided separately from the blanket 10, or may be attached to the blanket 10 (for example, sewn to the blanket 10).

[0058] Furthermore, by configuring at least one or both of the first extension member 31 and the second extension member 32 (both in the above example) from an elastic member, the blanket 10 can be easily attached to and detached from the table 11, and the blanket 10 can be securely attached to the table 11. Furthermore, one type of blanket 10 can be flexibly adapted to tables 11 of various sizes (for example, horizontal size).

[0059] Furthermore, by providing one or more additional extension members (in the above example, the third extension member 33 and the fourth extension member 34) in addition to the first extension member 31 and the second extension member 32, it is possible to flexibly adapt one type of blanket 10 to tables 11 of various sizes (e.g., table top portions having various thicknesses), and the attachment strength of the blanket 10 to the table 11 can also be improved.

[0060] In addition, by providing a fourth extension member 34 (stopper extension member) that exhibits a smaller expansion and contraction rate than the first extension member 31 and the second extension member 32, the fourth extension member 34 can be used as a stopper to prevent the blanket 10 from detaching from the table 11.

[0061] Furthermore, by making the spacing between the first extension member 31 and the second extension member 32 different from the spacing between the second extension member 32 and the third extension member 33, it is possible to finely adjust the range of the opening peripheral end 21 of the blanket 10 that can be attached to the table 11 while suppressing an increase in the number of extension members.

[0062] Furthermore, since the main body 20 of the blanket 10 has gathers 25, it is possible to prevent gaps from being generated that allow outside air to flow into the inner space of the blanket 10 when the blanket 10 is attached to the table 11, improving the heat retention of the inner space. Furthermore, since the main body 20 of the blanket 10 has a gathered silhouette, it is possible to make the area around the table 11 look neat and smart when the blanket 10 is attached to the table 11.

[0063] [Variations] In the above-described embodiment, as shown in Fig. 4, the first extension member 31 to the fourth extension member 34 are provided at the opening peripheral edge 21, but the number of extension members provided at the opening peripheral edge 21 is not limited. For example, only the first extension member 31 and the second extension member 32 may be provided at the opening peripheral edge 21. Furthermore, one or more additional extension members may be provided in addition to the first extension member 31 and the second extension member 32, three extension members may be provided at the opening peripheral edge 21, or five or more extension members may be provided at the opening peripheral edge 21.

[0064] In addition, in the above-described embodiment, the first extension member 31 to the third extension member 33 are made of an elastic member such as a rubber cord, but at least one of the first extension member 31 to the third extension member 33 may be made of a non-elastic member such as a fiber cord.

[0065] It should be noted that the embodiments and modifications disclosed in this specification are merely illustrative and should not be construed as limiting in all respects. The above-mentioned embodiments and modifications can be omitted, substituted, and modified in various forms without departing from the scope and spirit of the appended claims. For example, the above-mentioned embodiments and modifications may be combined in whole or in part, and embodiments other than those described above may be combined with the above-mentioned embodiments or modifications. In addition, the effects of the present disclosure described in this specification are merely illustrative, and other effects may be obtained. [Explanation of symbols]
