Description

この発明は、外表面に立体物を取り付けてなるランドセルに関する。 The present invention relates to a school bag having a three-dimensional object attached to its outer surface.

ランドセルの外表面には、通常、天然皮革や合成皮革、人工皮革などの比較的柔らかい素材のものが使用されている。そのため、長期間使用していると傷が目立ってくることがある。そこで従来から、特に傷つき易い蓋部をカバーで覆うことが広く行われている（例えば特許文献１参照）。 The outer surface of school bags is usually made of relatively soft materials such as natural leather, synthetic leather, and artificial leather. Therefore, scratches may become noticeable after long-term use. Therefore, conventionally, it has been widely practiced to cover the lid portion, which is particularly easily damaged, with a cover (see, for example, Patent Document 1).

特開２０１４－１１０８３５号公報JP 2014-110835 A

ところで近年のランドセルは、高級志向の高まりから素材自体にこだわっているものも多い。これに対してカバーは定期的な交換を前提とするものであって、通常、薄手の合成樹脂シートや布などの比較的安価な素材を使用しているものが多く、ランドセルの素材と相応していると必ずしもいえないことがある。また最近では、外表面に装飾を施したランドセルも登場してきているが、カバーを取り付けると折角の装飾が見えなくなってしまう。 By the way, many of the randoseru in recent years are particular about the material itself due to the increasing desire for luxury. Covers, on the other hand, are meant to be replaced on a regular basis, and are usually made of relatively inexpensive materials such as thin synthetic resin sheets and cloth, which are suitable for randoseru. There are some things that cannot always be said. Recently, some school bags with decorations on the outer surface have also appeared, but when the covers are attached, the special decorations become invisible.

そこで、カバーで覆わなくても外表面の傷つきを抑制することのできるランドセルの提供を目的とする。 Therefore, it is an object of the present invention to provide a school bag that can prevent the outer surface from being damaged without being covered with a cover.

本発明のランドセルは、上部に開口を有する収容部と、前記収容部に連結された背負いベルトと、前記収容部の開口に被さるとともに、収容部の底部近傍まで延設された蓋部と、前記蓋部の下端を前記収容部に留め付ける連結ベルトとを備えたランドセル本体の外表面に、立体物が部分的に取り付けられていることを特徴としている。 The school bag of the present invention comprises a storage section having an opening at the top, a shoulder belt connected to the storage section, a lid covering the opening of the storage section and extending to the vicinity of the bottom of the storage section, and The school bag is characterized in that a three-dimensional object is partially attached to the outer surface of the main body of the school bag, which includes a connecting belt that fastens the lower end of the lid portion to the storage portion.

前記立体物のランドセル本体に接触する部分が、ランドセル本体の外表面と同等又はそれよりも軟質な材質からなることが好ましい。また、前記立体物がクッション性を有することが好ましい。前記立体物が、可撓性を有するシート材を湾曲させることで構成されていることが好ましい。前記立体物が着脱可能であることが好ましい。 It is preferable that the portion of the three-dimensional object that contacts the main body of the school bag is made of a material that is as soft as or softer than the outer surface of the main body of the school bag. Moreover, it is preferable that the three-dimensional object has a cushioning property. It is preferable that the three-dimensional object is configured by curving a flexible sheet material. It is preferable that the three-dimensional object is detachable.

前記立体物が、前記蓋部、収容部及び背負いベルトの少なくともいずれかに取り付けられていることが好ましい。また、前記立体物が、蓋部と連結ベルトとの連結部に取り付けられていることが好ましい。特に前記連結ベルトが、ハトメ鋲によって蓋部に連結されており、ハトメ鋲の孔を利用して立体物が取り付けられていることが好ましい。 It is preferable that the three-dimensional object is attached to at least one of the lid portion, the storage portion, and the shoulder belt. Moreover, it is preferable that the three-dimensional object is attached to the connecting portion between the lid portion and the connecting belt. In particular, it is preferable that the connecting belt is connected to the lid portion with an eyelet rivet, and the three-dimensional object is attached using a hole in the eyelet rivet.

本発明のランドセルは、ランドセル本体の外表面に立体物が部分的に取り付けられているため、使用者がランドセルを背負ったまま壁にもたれ掛かったり、ランドセルを床に置いたりしても、ランドセル本体と対象物との間に立体物が介在することとなり、ランドセル本体の傷つきを抑制する（立体物をランドセル本体の防傷具として利用する）ことができる。 In the school bag of the present invention, since the three-dimensional object is partially attached to the outer surface of the school bag body, even if the user leans against the wall while carrying the school bag on his back or puts the school bag on the floor, the school bag body Since the three-dimensional object is interposed between the object and the object, damage to the school bag body can be suppressed (the three-dimensional object can be used as a scratch protector for the school bag body).

また、立体物のランドセル本体に接触する部分が、ランドセル本体の外表面と同等又はそれよりも軟質な材質からなれば、立体物によってランドセル本体を傷つけることもない。立体物がクッション性を有していれば、衝撃を吸収することができる。立体物が可撓性を有するシート材を湾曲させることで構成されていれば、簡単な構成でクッション性を付与することができる。また、装飾性に富んだ形状とすることもできる。また、立体物が着脱可能であれば、必要に応じて取り付けたり取り外したりすることができる。また、立体物の交換もし易い。 Moreover, if the part of the three-dimensional object that contacts the main body of the school bag is made of a material that is as soft as or softer than the outer surface of the main body of the school bag, the main body of the school bag will not be damaged by the three-dimensional object. If the three-dimensional object has cushioning properties, it can absorb the impact. If the three-dimensional object is configured by curving a flexible sheet material, it is possible to impart cushioning properties with a simple configuration. Moreover, it can be made into a shape rich in decorativeness. Also, if the three-dimensional object is detachable, it can be attached or detached as necessary. In addition, it is easy to exchange three-dimensional objects.

立体物が蓋部、収容部及び背負いベルトの少なくともいずれかに取り付けられていれば、当該部分の傷つきを抑制することができる。また、立体物が、蓋部と連結ベルトとの連結部に取り付けられていれば、連結部を立体物によって隠すことができる。そのため、縫い目や鋲などを隠すことができ、見栄えが良い。連結ベルトが、ハトメ鋲によって蓋部に連結されており、ハトメ鋲の孔を利用して立体物が取り付けられていれば、立体物の取り付けや取外しが簡単である。また、立体物を取り付けるための孔などを別途、蓋部に設ける必要も無く、立体物を取り外した状態での見栄えも良い。 If the three-dimensional object is attached to at least one of the lid portion, the storage portion, and the carrying belt, it is possible to prevent damage to the relevant portion. Moreover, if the three-dimensional object is attached to the connecting portion between the lid portion and the connecting belt, the connecting portion can be hidden by the three-dimensional object. Therefore, the seams and tacks can be hidden, and the appearance is good. If the connection belt is connected to the lid portion by means of eyelet studs, and the three-dimensional object is attached using the holes of the eyelet studs, the three-dimensional object can be easily attached and detached. In addition, there is no need to separately provide a hole or the like for attaching the three-dimensional object to the lid, and the appearance is good even when the three-dimensional object is removed.

次に、この発明のランドセルの一実施形態を図面に基づいて詳細に説明する。本発明のランドセル１は、図１に示すように、ランドセル本体２と、このランドセル本体２の外表面に取り付けられる立体物７とを備えている。 Next, one embodiment of the school bag of the present invention will be described in detail based on the drawings. A school bag 1 of the present invention comprises a school bag body 2 and a three-dimensional object 7 attached to the outer surface of the school bag body 2, as shown in FIG.

ランドセル本体２は、上部に開口３ａを有する収容部３と、収容部３に連結された背負いベルト４、４と、収容部３の開口３ａに被さるとともに、収容部３の底部近傍まで延設された蓋部５と、蓋部５の下端を収容部３の底部に着脱可能に留め付ける連結ベルト６（図２参照）とを備えている。 The school bag main body 2 includes a storage portion 3 having an opening 3a at the top, shoulder belts 4, 4 connected to the storage portion 3, and covering the opening 3a of the storage portion 3 and extending to the vicinity of the bottom portion of the storage portion 3. and a connecting belt 6 (see FIG. 2) that detachably fastens the lower end of the lid portion 5 to the bottom portion of the housing portion 3. As shown in FIG.

収容部３は箱状であって、ランドセル１を背負った際に背中側に位置する背板部と、この背板部と間隔を開けて対向する前板部と、背板部の側端と前板部の側端との間に介在する側板部と、底を塞ぐ底板部とから構成されており、内部に教科書などを収容するための空間が形成されている。各板部は、板状の芯材の表面を、天然皮革や合成皮革、人工皮革など（以下、単に皮革という）で覆うことで構成されている。なお背板部については、別途クッション材を入れても良い。 The housing part 3 is box-shaped and has a back plate part positioned on the back side when the school bag 1 is carried on the back, a front plate part opposed to the back plate part with a gap therebetween, and side ends of the back plate part. It is composed of a side plate portion interposed between the side ends of the front plate portion and a bottom plate portion covering the bottom, and a space for storing a textbook or the like is formed inside. Each plate portion is formed by covering the surface of a plate-shaped core material with natural leather, synthetic leather, artificial leather, or the like (hereinafter simply referred to as leather). A separate cushioning material may be added to the back plate portion.

背負いベルト４は、その一端が、背板部の上部近傍に取り付けられた背鐶（図示しない）に連結され、他端が、底板部の中央近傍に取り付けられたダルマ鐶（図示しない）に連結されている。この背負いベルト４は、可撓性を有する芯材の表面を皮革で覆うことで構成されており、身体に沿って比較的自由に変形できるようになっている。 One end of the shoulder belt 4 is connected to a back ring (not shown) attached near the top of the back plate portion, and the other end is connected to a daruma ring (not shown) attached near the center of the bottom plate portion. It is The shoulder belt 4 is constructed by covering the surface of a flexible core material with leather, so that it can be relatively freely deformed along the body.

蓋部５は、その一端が背板部の上端に連結されている。そして、収容部３の開口３ａ及び前板部の外面を覆いながら、他端が底板部近傍まで延びている。この蓋部５は、背負いベルト４と同様に、可撓性を有する芯材の表面を皮革で覆うことで構成されており、収容部３に被せた状態では、収容部３の外形に沿って弧を描くように変形し、収容部３から離した状態（蓋を開けた状態）では、ほぼ平らな板状に変形する。 One end of the lid portion 5 is connected to the upper end of the back plate portion. The other end extends to the vicinity of the bottom plate portion while covering the opening 3a of the housing portion 3 and the outer surface of the front plate portion. Like the shoulder belt 4, the cover 5 is made of a flexible core material covered with leather. It deforms to draw an arc, and when it is separated from the housing part 3 (the lid is opened), it deforms into a substantially flat plate shape.

連結ベルト６は、図２に示すように略Ｙ字状であって、二股に分かれた上端側がそれぞれ蓋部５に連結されている。連結には縫い付けや鋲による固定など種々の方法が採られる。下端には、収容部３の底板部の中央近傍に取り付けられた錠前（図示しない）に着脱可能に留め付けるための掛止板６ａが設けられている。連結ベルト６についても可撓性を有しており、収容部３の外形に沿って適宜変形する。 The connecting belt 6 is substantially Y-shaped as shown in FIG. Various methods such as sewing and fastening with rivets are used for connection. A latching plate 6a is provided at the lower end for detachably fastening to a lock (not shown) attached near the center of the bottom plate portion of the housing portion 3. As shown in FIG. The connecting belt 6 also has flexibility and deforms appropriately along the outer shape of the housing portion 3 .

立体物７は、可撓性を有するシート材を湾曲させたり、ヒダを形成する、すなわちクッション性を有するように立体形状とすることで構成されている。具体的には、図１及び図２に示すように、複数枚のシート材を湾曲させるとともにそれぞれ立設することで、バラやカーネーションなどの八重咲きの花を模した形状とされている。立体物７の厚みとしては十分な衝撃吸収性を得るために、例えば１ｃｍ以上とすることが好ましい。材質としては、蓋部５の表面を覆う皮革と同質で同色のものを使用することが好ましい。ただ、これに限らず、同質で異色のものを用いたり、異質で異色のものを用いても良い。例えば反射材であれば、ドライバーに注意を促すことができる。また、立体物７が蓋部５に接触した際の蓋部５への傷つきを抑制するために、少なくとも立体物７の蓋部５の表面と接触する部分は、蓋部５の表面と同等又はそれよりも軟質な材質を用いることが好ましい。 The three-dimensional object 7 is formed by bending a flexible sheet material or forming pleats, that is, forming a three-dimensional shape so as to have cushioning properties. Specifically, as shown in FIGS. 1 and 2, a plurality of sheet members are curved and erected to form a shape that imitates double flowers such as roses and carnations. The thickness of the three-dimensional object 7 is preferably 1 cm or more, for example, in order to obtain sufficient impact absorption. As for the material, it is preferable to use the same material and the same color as the leather covering the surface of the lid portion 5 . However, it is not limited to this, and materials of the same quality and different color may be used, or materials of different quality and different color may be used. For example, reflective materials can alert drivers. Further, in order to suppress damage to the lid portion 5 when the three-dimensional object 7 contacts the lid portion 5, at least the portion of the three-dimensional object 7 that contacts the surface of the lid portion 5 is equal to or greater than the surface of the lid portion 5. It is preferable to use a softer material than that.

このような立体物７は、蓋部５の外面全体に取り付けられるのではなく、部分的に取り付けられる。本実施形態では、図１及び図２に示すように、蓋部５の中間部近傍と下端近傍の２箇所に取り付けられている。また、下端側の立体物７は、蓋部５と連結ベルト６との連結部に取り付けられている。取付に際しては、蓋部５と連結ベルト６とを連結するハトメ鋲８の孔８ａを利用している。また、雄ネジ９と雌ネジ１０とからなる取付具を介して取り付けている（図３参照）。 Such a three-dimensional object 7 is attached not to the entire outer surface of the lid portion 5 but to a part thereof. In this embodiment, as shown in FIGS. 1 and 2, they are attached at two locations near the middle portion and near the lower end of the lid portion 5 . Moreover, the three-dimensional object 7 on the lower end side is attached to the connecting portion between the lid portion 5 and the connecting belt 6 . For attachment, the hole 8a of the eyelet rivet 8 that connects the lid portion 5 and the connecting belt 6 is used. Moreover, it is attached via a fixture consisting of a male screw 9 and a female screw 10 (see FIG. 3).

雌ネジ１０は、予め立体物７に取り付けておくものであって、雄ネジ９と螺合するための本体ネジ１１と、本体ネジ１１を立体物７に取り付けるための取付ネジ１２とからなる。本体ネジ１１は、雌ネジ部１１ａが形成された軸部１１ｂと、軸部１１ｂの上部から径外方向に延設されたフランジ部１１ｃとを有している。取付ネジ１２は、雌ネジ部１１ａに対応する雄ネジ部１２ａと、雄ネジ部１２ａの上端に設けられた円板状のネジ頭１２ｂとを有している。そして、取付ネジ１２の雄ネジ部１２ａを立体物７の内側から孔７ｃを介して外方に突出させるとともに、その突出した雄ネジ部１２ａに、本体ネジ１１の雌ネジ部１１ａを立体物７の外側から螺合させることで、ネジ頭１２ｂとフランジ部１１ｃとによって立体物７を挟持し、雌ネジ１０が立体物７に回転不可の状態で固定されている。なお、雌ネジ１０の立体物７への固定をより強固なものとするために、フランジ部１１ｃやネジ頭１２ｂの表面（立体物７に当接する面）に接着剤を塗布したり、粘着性の両面テープを貼り付けておいても良い。 The female screw 10 is attached to the three-dimensional object 7 in advance, and consists of a body screw 11 for screwing with the male screw 9 and a mounting screw 12 for attaching the body screw 11 to the three-dimensional object 7. - 特許庁The body screw 11 has a shaft portion 11b formed with a female thread portion 11a and a flange portion 11c extending radially outward from the upper portion of the shaft portion 11b. The mounting screw 12 has a male threaded portion 12a corresponding to the female threaded portion 11a, and a disc-shaped screw head 12b provided at the upper end of the male threaded portion 12a. Then, the male threaded portion 12a of the mounting screw 12 is projected outward from the inside of the three-dimensional object 7 through the hole 7c, and the female threaded portion 11a of the body screw 11 is inserted into the projected male threaded portion 12a. The three-dimensional object 7 is held between the screw head 12b and the flange portion 11c by screwing from the outside of the female screw 10, and the female screw 10 is fixed to the three-dimensional object 7 in a non-rotatable state. In order to fix the female screw 10 to the three-dimensional object 7 more firmly, the surface of the flange portion 11c and the screw head 12b (the surface in contact with the three-dimensional object 7) may be coated with an adhesive or an adhesive agent. It is also possible to stick the double-sided tape on it.

立体物７の蓋部５の外面への取り付けは、雌ネジ１０の軸部１１ｂを、蓋部５の外面側からハトメ鋲８の孔８ａに挿通し、蓋部５の内面側（連結ベルト６の内面側）から、雄ネジ９の雄ネジ部９ａを雌ネジ部１１ａに螺合し、雌ネジ１０のネジ頭１２ｂと雄ネジ９のネジ頭９ｂとで蓋部５（及び連結ベルト６）を挟持する、又は、雄ネジ部９ａの全長を雌ネジ部１１ａに完全に螺合させることで行う。このような取り付け方法であれば、雄ネジ９を緩めるだけで簡単に立体物７を取り外すことができ、例えば破損時や汚染時に気軽に交換することができる。なお、ネジの緩みを抑制するため、雌ネジ１０を蓋部５に固定し、雄ネジ９を立体物７の内側に収容するようにしても良い。 To attach the three-dimensional object 7 to the outer surface of the lid portion 5, the shaft portion 11b of the female screw 10 is inserted from the outer surface side of the lid portion 5 into the hole 8a of the eyelet rivet 8, and the inner surface side of the lid portion 5 (the connecting belt 6 The male screw portion 9a of the male screw 9 is screwed into the female screw portion 11a from the inner surface side of the male screw 9, and the screw head 12b of the female screw 10 and the screw head 9b of the male screw 9 connect the lid portion 5 (and the connecting belt 6). or by completely screwing the entire length of the male threaded portion 9a into the female threaded portion 11a. With such an attachment method, the three-dimensional object 7 can be easily removed simply by loosening the male screw 9, and can be easily replaced when it is damaged or contaminated, for example. In order to prevent loosening of the screw, the female screw 10 may be fixed to the lid portion 5 and the male screw 9 may be housed inside the three-dimensional object 7 .

立体物７の蓋部５への取付手段としては上記ネジによる螺合の他に、磁石や面ファスナーなどによって着脱可能に取り付けても良いし、鋲や接着剤などによって着脱不可に取り付けても良い。また、ネジ挿通用の孔や、対で使用する磁石、面ファスナーの一方を蓋部５に規則的に設けておき（並行配置、千鳥配置など）、好きな位置に立体物７を取り付けられるようにしても良い。 As a means for attaching the three-dimensional object 7 to the lid portion 5, in addition to screwing with screws, magnets, hook-and-loop fasteners, or the like may be used to attach the three-dimensional object 7 to the lid portion 5 in a detachable manner. . In addition, holes for screw insertion, magnets to be used in pairs, and hook-and-loop fasteners are regularly provided on the lid portion 5 (parallel arrangement, zigzag arrangement, etc.) so that the three-dimensional object 7 can be attached at a desired position. You can do it.

図４は、異なる形状の立体物７Ａを蓋部５に取り付けた状態を示したものである。この立体物７Ａはリボンを模したものであって、可撓性を有する帯状のシート材の両端を連結して扁平な環状に形成するとともに、長手方向の中心近傍を縛ることで構成されている。このように構成すれば、図５に示すように、リボンの両端に、可撓性を有するシート材を湾曲させてなるクッション部７ａが形成されることとなる。また、リボンの中心にもヒダ７ｂが形成され、この部分にもクッション性を持たせることができる。この立体物７Ａは、蓋部５の下端近傍であって、蓋部５と連結ベルト６との連結部に取り付けられている。そのため、連結部を覆い隠すことができることは勿論のこと、収容部３の開口３ａを開放した際、周囲の物に勢い良く衝突する可能性がある蓋部５の下端近傍を保護することができる。
なお、この立体物７Ａは、長手方向の両端部近傍が蓋部５に固定されている。このように２ヶ所以上で固定すれば、立体物７Ａの回転が拘束され、取付状態が安定する。なお、取り付け（固定）に際しては、孔８ａを用いての図３に示すネジによる螺合の他、種々の方法を採用し得る。 FIG. 4 shows a state in which three-dimensional objects 7A having different shapes are attached to the lid portion 5. As shown in FIG. This three-dimensional object 7A imitates a ribbon, and is constructed by connecting both ends of a flexible strip-shaped sheet material to form a flat annular shape, and binding the vicinity of the center in the longitudinal direction. . With this configuration, as shown in FIG. 5, cushion portions 7a formed by bending a flexible sheet material are formed at both ends of the ribbon. A fold 7b is also formed in the center of the ribbon, and this portion can also be provided with a cushioning property. The three-dimensional object 7A is attached to the connecting portion between the lid portion 5 and the connecting belt 6 near the lower end of the lid portion 5 . Therefore, not only can the connecting portion be covered, but also the vicinity of the lower end of the lid portion 5, which may collide with surrounding objects with force when the opening 3a of the housing portion 3 is opened, can be protected. .
The three-dimensional object 7A is fixed to the lid portion 5 in the vicinity of both ends in the longitudinal direction. If it is fixed at two or more places in this way, the rotation of the three-dimensional object 7A is restrained, and the mounting state is stabilized. For mounting (fixing), various methods can be adopted other than screwing with screws shown in FIG. 3 using holes 8a.

図６は、立体物７を背負いベルト４に部分的に取り付けた状態を示している。背負いベルト４は、通常、収容部３内の教科書等を取り出す際に下側に位置するため、載置面と擦れるなどして傷がつき易いが、このように背負いベルト４の前面に立体物７を取り付けることで、背負いベルト４と載置面との間に立体物７を位置させることができ、背負いベルト４の傷つきを抑制することができる。なお、取り付ける場所は特に限定されないが、背負った際に胸の高さに位置するようにすることが好ましい。取付に際しては、蓋部５への取り付けと同じように、ネジ留めや磁石、面ファスナーなど種々の方法で固定することができる。なお、ネジ留めするにあたって、ベルト長さを調節するためのベルト孔を利用すれば、新たに孔を開ける必要もない。また、ベルト孔の間隔と同じ間隔で孔４ａを上側に設けていけば、違和感無く孔を設けることができる。 FIG. 6 shows a state in which the three-dimensional object 7 is partially attached to the shoulder belt 4 . Since the backpack belt 4 is normally positioned on the lower side when a textbook or the like is taken out of the storage section 3, it is easily damaged by rubbing against the placement surface. By attaching 7, the three-dimensional object 7 can be positioned between the backpack belt 4 and the mounting surface, and damage to the backpack belt 4 can be suppressed. Although there is no particular limitation on where to attach it, it is preferable to position it at chest height when carrying it on the back. As with the attachment to the lid portion 5, it can be fixed by various methods such as screwing, magnets, and hook-and-loop fasteners. If the belt holes for adjusting the length of the belt are used for screwing, there is no need to drill new holes. Also, if the holes 4a are provided on the upper side at the same intervals as the intervals of the belt holes, the holes can be provided without discomfort.

図７は、立体物７を収容部３の側板部に部分的に取り付けた状態を示している。このように、収容部３の側面に立体物７を取り付けることで、収容部３の側面の傷つきを抑制することができる。立体物７は、上記ネジ留めや磁石、面ファスナーなど種々の方法で固定する。但し、ランドセルは、背負いベルト４を下にする置き方、蓋部５を下にする置き方、収容部３の底板部を下にする置き方のように複数の置き方が想定されるため、どのような置き方であっても所望の防傷効果が得られるよう、立体物７の位置が変わったり、めくれたりすることのない固定方法が好ましい。 FIG. 7 shows a state in which the three-dimensional object 7 is partially attached to the side plate portion of the housing portion 3. As shown in FIG. By attaching the three-dimensional object 7 to the side surface of the housing portion 3 in this way, the side surface of the housing portion 3 can be prevented from being damaged. The three-dimensional object 7 is fixed by various methods such as screwing, magnets, and hook-and-loop fasteners. However, since the school bag can be placed in a plurality of ways, such as placing the backpack belt 4 downward, placing the lid 5 downward, and placing the bottom plate of the storage unit 3 downward, A fixing method that does not change the position of the three-dimensional object 7 or turn it over is preferable so that a desired scratch-proof effect can be obtained regardless of how it is placed.

以上に、この発明の実施形態について説明したが、この発明は上記実施形態に限定されるものではなく、この発明の範囲内で種々変更して実施することが可能である。例えば、上記実施形態では、立体物として、可撓性を有するシートを八重咲きの花やリボンの形状に構成したものを用いていたが、クッション性を高めるために、シート材の内側にスポンジやゴム、バネ、ジェル、綿、低反発素材などの弾性体を内包しても良い。また、シート材の材質としては皮革に限らず、織物地、網地、レース地、フェルト、不織布、紙などであっても良い。また必ずしもシート材を用いる必要は無く、立体的な形状とされたスポンジ、ゴム、低反発素材やこれらの積層物で立体物を構成しても良い。形状も八重咲きの花やリボンに限られること無く、図８ａ、図８ｂに示すように、ハート型や一重咲きの花を模したものであっても良い。さらに、綿を詰めたぬいぐるみ（図８ｃ参照）や、芯材の周りに毛皮を張り付けてなるポンポン（ボンボン：図８ｄ参照）を立体物として用いても良い。大きさについても種々採用し得る。なお、例えば蓋部５に取り付けるにあたって、蓋部５の幅と同等もしくはやや幅広の立体物を用いれば、蓋部５の縁部まで保護することができる。
また、取り付ける個数は１つに限られず、複数取り付けても良い。特に立体物同士を結ぶ仮想線によって多角形を描くように取り付けた場合、立体物が脚のように作用するため、ランドセル本体２が載置面に直接接することを防ぐことができ、高い防傷効果が期待できる。また、図８ｅに示すように、同一形状の立体物を複数並べた状態で取り付ければ、華やかさを演出することもできる。立体物を取り付ける位置は、前記蓋部、収容部及び背負いベルトのうちのいずれか１ヶ所ではなく、複数の位置に取り付けても良い。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention. For example, in the above-described embodiment, a flexible sheet configured in the shape of a double flower or a ribbon was used as the three-dimensional object. , springs, gel, cotton, and low-resilience materials. Further, the material of the sheet material is not limited to leather, and may be woven fabric, mesh fabric, lace fabric, felt, non-woven fabric, paper, or the like. Moreover, it is not always necessary to use a sheet material, and a three-dimensional object may be formed of three-dimensionally shaped sponge, rubber, low-resilience material, or a laminate thereof. The shape is not limited to a double-flowered flower or ribbon, and may be heart-shaped or a single-flowered flower as shown in FIGS. 8a and 8b. Furthermore, a stuffed animal stuffed with cotton (see FIG. 8c) or a pom-pom (see FIG. 8d) made by pasting fur around a core material may be used as a three-dimensional object. Various sizes can also be adopted. For example, when attaching to the lid portion 5, if a three-dimensional object having a width equal to or slightly wider than the width of the lid portion 5 is used, even the edges of the lid portion 5 can be protected.
Also, the number of attachments is not limited to one, and a plurality of attachments may be made. In particular, when three-dimensional objects are attached so as to draw a polygon by imaginary lines connecting three-dimensional objects, the three-dimensional objects act like legs, so that the main body 2 of the school bag can be prevented from coming into direct contact with the mounting surface, resulting in high scratch resistance. expected to be effective. In addition, as shown in FIG. 8e, if a plurality of three-dimensional objects having the same shape are arranged side by side and attached, it is possible to produce a splendid appearance. The three-dimensional object may be attached to a plurality of positions instead of any one of the lid portion, the storage portion, and the shoulder belt.
