Description

本発明は、引手付き椅子に係わり、更に詳しくは椅子を移動させることが容易な引手付き椅子に関するものである。   The present invention relates to a chair with a handle, and more particularly to a chair with a handle that allows easy movement of the chair.

従来から、特許文献1の図1に記載されているように、学童用の木製椅子では背凭れ板の中央部をくり抜いて引手部を形成しているものは一般的である。しかし、キャスター付きの回転椅子では、背凭れ部には引手部を設けたものは皆無である。   Conventionally, as described in FIG. 1 of Patent Document 1, in a wooden chair for school children, a central portion of a backrest plate is cut out to form a handle portion. However, in a swivel chair with casters, there is no one that has a handle part in the backrest part.

通常、背凭れ部に引手部が無い場合には、該背凭れ部の上端を持って手前に引くことになるが、キャスターが床面をスムーズに転がらない場合や、床面に段差が有る等の障害物がある場合には、椅子が倒れることもある。つまり、背凭れ部の上端は、最も重心から離れた位置であり、またキャスターと床面の接触点から最も離れて回転モーメントが大きく作用する位置であり、本質的に最も倒れ易いのである。
特許第2624933号公報(図1)
Normally, when there is no handle part in the backrest part, it will be pulled forward with the upper end of the backrest part, but if the caster does not roll the floor surface smoothly or there is a step on the floor surface etc. If there are other obstacles, the chair may fall over. That is, the upper end of the backrest is the position farthest from the center of gravity, and is the position where the rotational moment acts most away from the contact point between the caster and the floor surface.
Japanese Patent No. 2624933 (FIG. 1)

そこで、本発明が前述の状況に鑑み、解決しようとするところは、脚部の下端にキャスター等の移動手段を取付けるとともに、該脚部で支持された座部の背後部に背凭れ部を設けた回転椅子等において、背凭れ部がクッション体やインナーシェル、アウターシェルで構成された複合構造を有するものでも該引手部を設けて移動させ易いようにした引手付き椅子を提供する点にある。   Therefore, in view of the situation described above, the present invention intends to solve the problem that a moving means such as a caster is attached to the lower end of the leg portion, and a backrest portion is provided behind the seat portion supported by the leg portion. The present invention also provides a chair with a handle in which the backrest portion has a composite structure in which the backrest portion is composed of a cushion body, an inner shell, and an outer shell so that the handle portion can be easily moved.

本発明は、前述の課題解決のために、脚部の下端にキャスター等の移動手段を取付けるとともに、該脚部で支持された座部の背後部に背凭れ部を設け、該背凭れ部の背面側に位置する合成樹脂製のアウターシェルに、引手部を形成した椅子であって、前記引手部として、前記アウターシェルの一部に凹陥部を形成するとともに、該凹陥部の中央部に横長の膨出部を形成し、該膨出部の上面側を指が掛からない平面部とし、該膨出部とそれより下側の凹陥部の間は開放し、前記膨出部の内面側に内接可能な形状の本体部に下方へ開放した凹部を形成した指当て部材を、前記アウターシェルの前面側から取付けることにより、該指当て部材の凹部を前記膨出部の下側の凹陥部に面してなる引手付き椅子を構成した(請求項1)。 In order to solve the above-mentioned problems, the present invention attaches a moving means such as a caster to the lower end of the leg portion, and provides a backrest portion behind the seat portion supported by the leg portion. A chair in which a handle portion is formed on an outer shell made of synthetic resin located on the back side, and a recess portion is formed in a part of the outer shell as the handle portion, and at a central portion of the recess portion. A horizontally long bulging portion is formed, and the upper surface side of the bulging portion is a flat portion on which a finger is not hooked, and the space between the bulging portion and the recessed portion below the bulging portion is opened, and the inner surface side of the bulging portion A finger contact member formed with a recessed portion opened downward in a body portion that can be inscribed in is attached from the front side of the outer shell, so that the recessed portion of the finger contact member is recessed below the bulging portion. The chair with a handle which faces a part was constituted (claim 1).

ここで、前記指当て部材は、前記本体部の両側端に取付部を形成し、該指当て部材を前記アウターシェルの前面側から前記膨出部の内面側に内接させるとともに、両取付部をアウターシェルの前面側に形成した固定台にネジで取付けることが好ましい(請求項2)。 Here, the finger contact member is formed with attachment portions on both side ends of the main body portion, the finger contact member is inscribed from the front surface side of the outer shell to the inner surface side of the bulging portion, and both attachment portions Is preferably attached to a fixing base formed on the front side of the outer shell with a screw .

また、前記膨出部の上面側を指が掛からない平面部とするとともに、該平面部が前記膨出部の突出側へ向けて下方傾斜してなるとより好ましい(請求項)。 Also, with the upper surface of the bulging portion and flat portion not applied finger, and more preferably flat portion is formed by downwardly inclined toward the projecting side of the bulging portion (claim 3).

以上にしてなる請求項1に係る発明の引手付き椅子は、背凭れ部を構成する合成樹脂製のアウターシェルの成形とともに、背凭れ部の背面に引手部を設けることができ、該引手部を引くことによって容易に椅子を手前に移動させることができる。また、背凭れ部の上端よりも下方位置に引手部が設けられているので、より重心の低い位置を引くことになり、若しくは脚部の下端に対する回転モーメントが小さくなるので、不意に椅子が倒れることがなくなるのである。また、学童が使用する場合にも、引手部が低い位置にあるので、椅子を手前に引く作業がし易くなり、扱い易いものとなる。引手部は、凹陥部の中に形成された膨出部に設けたので、アウターシェルから大きく突出することがなく、通常は邪魔にならず、また意匠性にも優れたものとなる。しかも、膨出部の下面側に下方から指を掛ける凹部を形成したので、更に低い位置で椅子を引くことができるので、より安定に椅子を移動させることができる。更に、下方に向いた凹部を有する引手部は、アウターシェルに、前面側の開放部から凹部を形成した指当て部材を取付ける分割成形により形成するので、各部材は二つ割の金型で成形することが可能であり、そのため金型コストを低減することができる。 The chair with a handle of the invention according to claim 1 as described above can be provided with a handle portion on the back surface of the backrest portion together with the molding of the outer shell made of synthetic resin constituting the backrest portion. By pulling, the chair can be easily moved to the front. In addition, since the handle portion is provided at a position below the upper end of the backrest portion, the lower center of gravity is pulled, or the rotational moment with respect to the lower end of the leg portion is reduced, so that the chair collapses unexpectedly. It will disappear. In addition, when a schoolchild uses it, the handle portion is at a low position, so that the task of pulling the chair forward becomes easy and easy to handle. Since the pulling portion is provided at the bulging portion formed in the recessed portion, the pulling portion does not protrude greatly from the outer shell, and usually does not get in the way and has excellent design. And since the recessed part which hooks a finger from the downward direction was formed in the lower surface side of a bulging part, since a chair can be pulled in a still lower position, a chair can be moved more stably. Further, the pulling portion having the concave portion facing downward is formed by split molding in which a finger contact member having a concave portion is formed on the outer shell from the opening portion on the front side, so each member is molded with a split mold. It is possible to reduce the mold cost.

請求項2によれば、アウターシェルへ指当て部材をネジ止めにより取付けることができる。 According to the second aspect, the finger contact member can be attached to the outer shell by screwing.

請求項3によれば、前記膨出部の上面側を指が掛からない平面部としたことにより、間違いなく指を膨出部の下面側の凹部に掛けるように誘導することができ、予期しない使用形態を排除でき、更に前記平面部を前記膨出部の突出側へ向けて下方傾斜させることにより、強制的に膨出部の上面側に指を掛けられなくすることができる。 According to the third aspect of the present invention, since the upper surface side of the bulging portion is a flat surface portion on which the finger does not hang, the finger can definitely be guided to hang on the concave portion on the lower surface side of the bulging portion, which is unexpected. The usage form can be eliminated , and further, by tilting the flat portion downward toward the protruding side of the bulging portion, it is possible to forcibly prevent the finger from being hooked on the upper surface side of the bulging portion.

次に、添付図面に示した実施形態に基づき、本発明を更に詳細に説明する。図1は本発明に係る引手付き椅子の全体側面図、図2〜図6は第1実施形態の要部を示し、図中符号1は脚部、2は座部、3は背凭れ部、4は背凭れ支持杆をそれぞれ示している。   Next, the present invention will be described in more detail based on the embodiments shown in the accompanying drawings. FIG. 1 is an overall side view of a chair with a handle according to the present invention, FIGS. 2 to 6 show a main part of the first embodiment, in which 1 is a leg, 2 is a seat, 3 is a backrest, Reference numeral 4 denotes a back support heel.

本発明に係る椅子は、前記脚部1の軸部5の上端に座部を回転可能且つ高さ調節可能に支持するとともに、該座部2の背後部に背凭れ部3を背凭れ支持杆4にて前後傾動可能に支持したものである。そして、前記脚部1の軸部5の下端から放射状に延びた支脚6,…の先端部下端にそれぞれキャスター7,…を設け、床面を転動して移動可能としたものである。ここで、本発明では、椅子の構造は前述のキャスター付きの回転椅子に限定されず、脚部1の下端にキャスター等の移動手段を取付けるとともに、該脚部1で支持された座部2の背後部に背凭れ部3を設けた椅子であれば広く適用できるものである。   The chair according to the present invention supports the seat portion at the upper end of the shaft portion 5 of the leg portion 1 so that the seat portion can be rotated and the height can be adjusted, and the backrest portion 3 is supported at the back of the seat portion 2. 4 is supported so that it can tilt forward and backward. Then, casters 7,... Are respectively provided at the lower ends of the tips of the support legs 6,... Extending radially from the lower end of the shaft portion 5 of the leg 1, so that they can move by rolling on the floor surface. Here, in the present invention, the structure of the chair is not limited to the above-described swivel chair with casters, and a moving means such as a caster is attached to the lower end of the leg 1 and the seat 2 supported by the leg 1 is provided. The present invention can be widely applied to a chair provided with a backrest 3 at the back.

本発明において、前記背凭れ部3は、図示しないインナーシェルの前面側にクッション体8を取付けるとともに、インナーシェルの背面側をアウターシェル9で外覆した構造のものである。前記インナーシェルとアウターシェル9は、合成樹脂製で成形されたものでり、ウレタン発泡体等で形成したクッション体8をインナーシェルの前面側に配して、それをクロス等の表皮シートで外覆して製造する。尚、前記背凭れ支持杆4の上端部はインナーシェルに強固に固定され、前記アウターシェル9の下部に設けた開口10から引き出されている。ここで、前記背凭れ支持杆4は、中央部に1本には限らず、左右に1本ずつ設けることもある。   In the present invention, the backrest 3 has a structure in which the cushion body 8 is attached to the front side of an inner shell (not shown) and the back side of the inner shell is covered with an outer shell 9. The inner shell and the outer shell 9 are made of synthetic resin, and a cushion body 8 formed of urethane foam or the like is arranged on the front side of the inner shell, and the outer shell 9 is covered with a skin sheet such as a cloth. Manufacturing by covering. Note that the upper end portion of the backrest support rod 4 is firmly fixed to the inner shell and pulled out from an opening 10 provided in the lower portion of the outer shell 9. Here, the backrest support rod 4 is not limited to one at the center, but may be provided one at the left and right.

そして、前記背凭れ部3の背面側に位置する合成樹脂製のアウターシェル9に、引手部11を一体成形若しくは分割成形にて形成するのである。本実施形態では、前記アウターシェル9の中央部やや上位に前記引手部11を形成している。ここで、前記引手部11を設ける位置は、前記背凭れ部3の左右中央部で、可能な限り下方にすることが安定性の観点から好ましいのである。前述の左右に1本ずつ背凭れ支持杆4,4を設ける場合は、両背凭れ支持杆4,4の間で、アウターシェル9の下部位置に前記引手部11を設けることができる。   And the handle part 11 is formed in the synthetic resin outer shell 9 located in the back side of the backrest part 3 by integral molding or division molding. In the present embodiment, the handle portion 11 is formed slightly above the center of the outer shell 9. Here, it is preferable from the standpoint of stability that the position where the pulling portion 11 is provided is as low as possible in the left and right central portions of the backrest portion 3. When the backrest support rods 4, 4 are provided one by one on the left and right sides, the handle portion 11 can be provided at a lower position of the outer shell 9 between the backrest support rods 4, 4.

具体的には、図3〜図6に示すように、前記引手部11として、前記アウターシェル9の一部に略半球面状の凹陥部12を形成するとともに、該凹陥部12の中央部に横長の膨出部13を該アウターシェル9の輪郭から若干突出するように形成し、該膨出部13の下面側に下方から指を掛ける凹部14を形成している。更に、前記引手部11は、前記膨出部13の上面側を指が掛からない平面部15とするとともに、該平面部15が前記膨出部13の突出側へ向けて下方傾斜していることが好ましい。   Specifically, as shown in FIGS. 3 to 6, a substantially hemispherical concave portion 12 is formed in a part of the outer shell 9 as the pulling portion 11, and at the central portion of the concave portion 12. A horizontally long bulging portion 13 is formed so as to slightly protrude from the contour of the outer shell 9, and a concave portion 14 is formed on the lower surface side of the bulging portion 13 from which a finger is hung from below. Further, the pulling portion 11 has the upper surface side of the bulging portion 13 as a flat surface portion 15 on which no finger is hooked, and the flat surface portion 15 is inclined downward toward the protruding side of the bulging portion 13. Is preferred.

ここで、前記膨出部13の下側の凹陥部12は、指を差し入れる空間部となり、そして前記凹部14を下方から掛けることができるようになっている。また、本実施形態では、前記膨出部13の上側にも凹陥部12が存在し、指を差し入れることが可能であるが、この膨出部13の上側面を前記膨出部13の突出側へ向けて下方傾斜している平面部15としてことにより、指を掛けることができないよいうにしている。こうすることによって、より低い位置にある前記凹部14に指を掛けるように誘導するのである。尚、この目的のためには、前記膨出部13の上側に凹陥部12を形成せずに、前記アウターシェル9の輪郭を延長した形状にしても良いのである。しかし、人間工学的には、前記膨出部13の上面側の平面部15に親指を当てて、前記凹部14に掛けたその他の指とで当該膨出部13を上下から挟んで使用できる本実施形態の方が優れている。   Here, the recessed part 12 below the bulging part 13 becomes a space part into which a finger is inserted, and the recessed part 14 can be hung from below. Further, in this embodiment, the recessed portion 12 is also present on the upper side of the bulging portion 13 and a finger can be inserted, but the upper side surface of the bulging portion 13 is projected from the bulging portion 13. By using the flat portion 15 that is inclined downward toward the side, the finger cannot be hung. By doing so, it is guided to put a finger on the recess 14 at a lower position. For this purpose, the contour of the outer shell 9 may be extended without forming the recessed portion 12 above the bulging portion 13. However, ergonomically, a book that can be used by placing the thumb on the flat portion 15 on the upper surface side of the bulging portion 13 and sandwiching the bulging portion 13 from above and below with other fingers hung on the concave portion 14. The embodiment is superior.

以上説明した第1実施形態では、前記アウターシェル9の成形と同時に、前記凹部14を含めて引手部1の全体を一体成形したが、金型の抜き方向と該凹部14の向きが交差するので、通常の二つ割の金型で成形することが不可能であり、そのため凹部14を別の割金型で成形する必要があり、金型コストが上昇しコスト高となる。そこで、図7及び図8に示す第2実施形態では、前記アウターシェル9の大部分を通常の二つ割の金型で成形し、前記引手部11の凹部14に対応する部分を別部材として小型の金型で成形し、それらを組合わせて第1実施形態と同様な引手部11を形成する。   In the first embodiment described above, the entire handle portion 1 including the concave portion 14 is integrally formed simultaneously with the molding of the outer shell 9, but the direction in which the mold is pulled out intersects with the direction of the concave portion 14. Therefore, it is impossible to mold with a normal split mold, and therefore it is necessary to mold the recess 14 with another split mold, which increases the mold cost and increases the cost. Therefore, in the second embodiment shown in FIGS. 7 and 8, most of the outer shell 9 is molded with a normal two-part mold, and the portion corresponding to the concave portion 14 of the pull handle portion 11 is used as a separate member. Forming with a small mold and combining them, the handle part 11 similar to the first embodiment is formed.

この場合、前記アウターシェル9には、引手部11として、前記同様な凹陥部12と膨出部13及び平面部15を一体成形し、該膨出部13とそれより下側の凹陥部12の間は開放されている。そして、別部材として成形する指当て部材16は、前記膨出部13の内面側に内接可能な形状の本体部17に下方へ開放した凹部14を形成するとともに、本体部17の両側端に取付部18,18を形成したものである。そして、前記指当て部材16を前記アウターシェル9の前面側から前記膨出部13の内面側に内接させるとともに、両取付部18,18を、アウターシェル9の前面側に形成した固定台19,19にネジ20,20で取付ける。この状態で、前記指当て部材16の凹部14は、前記膨出部13の下側の凹陥部12に面することになる。ここで、前記膨出部13と平面部15も前記指当て部材16の一部として成形することも可能である。   In this case, the outer shell 9 is integrally formed with the recessed portion 12, the bulging portion 13 and the flat portion 15 similar to the pulling portion 11, and the bulging portion 13 and the recessed portion 12 below the bulging portion 13. The space is open. The finger contact member 16 to be molded as a separate member forms a recessed portion 14 opened downward in the body portion 17 having a shape that can be inscribed on the inner surface side of the bulging portion 13, and is formed on both side ends of the body portion 17. The attachment portions 18, 18 are formed. The finger rest member 16 is inscribed from the front surface side of the outer shell 9 to the inner surface side of the bulging portion 13, and both mounting portions 18 and 18 are formed on the front surface side of the outer shell 9. , 19 with screws 20, 20. In this state, the concave portion 14 of the finger contact member 16 faces the concave portion 12 below the bulging portion 13. Here, the bulging portion 13 and the flat portion 15 can also be formed as a part of the finger contact member 16.
