上記特許文献1に記載された机では、2つの脚体を本体に固定するために、4本のボルトのそれぞれにナットを螺合しなければならず、机の組み立て作業に時間がかかるという問題があった。また、学校などで使用される机では、学年が変わるごとに児童の身長や好みに応じて本体の高さを調整する必要があるが、机の数が多い(例えば1クラスに40台)だけでなく、作業が短期間(例えば3月)に集中するため、作業負担が大きくなり過ぎるという問題があった。   In the desk described in the above-mentioned patent document 1, in order to fix the two legs to the main body, a nut must be screwed into each of the four bolts, and it takes time to assemble the desk. was there. For desks used in schools, etc., it is necessary to adjust the height of the main body according to the height and preference of the child whenever the grade changes, but there are only a large number of desks (for example, 40 units per class). In addition, since the work is concentrated in a short period (for example, March), there is a problem that the work load becomes too large.

本発明は上記問題に対処するためになされたものであり、短時間で簡単に組み立てることができる支持台、支持台を構成する支持部の回動を阻止する回動阻止部材およびその製造方法を提供することを目的とする。   The present invention has been made to cope with the above-described problem, and provides a support base that can be easily assembled in a short time, a rotation prevention member that prevents the rotation of the support portion constituting the support base, and a method for manufacturing the same. The purpose is to provide.

上記目的を達成するため、本発明の支持台の特徴は、上下方向に間隔を隔てて水平方向に向けて設けられた2つの第1貫通孔を有し、支持対象を支持する支持部と、2つの前記第1貫通孔のそれぞれに対応する2つの第2貫通孔を有し、前記支持部の荷重を受ける脚部と、一方の前記第1貫通孔および一方の前記第2貫通孔に挿入される棒状の雄ねじ部と前記雄ねじ部に螺合される雌ねじ部とを有し、前記支持部に前記脚部を接続する接続部材と、前記雄ねじ部を中心とする前記支持部の回動を阻止する回動阻止部材とを備え、前記回動阻止部材は、前記支持部および前記脚部の一方に対して前記接続部材で固定される本体部と、前記本体部に設けられ、他方の前記第1貫通孔および他方の前記第2貫通孔に挿入されるピンとを有することにある。   In order to achieve the above object, the feature of the support base of the present invention includes two first through holes provided in the horizontal direction at intervals in the vertical direction, and a support portion that supports a support target; Two second through-holes corresponding to each of the two first through-holes, and inserted into the leg portion receiving the load of the support portion, one of the first through-holes and one of the second through-holes A rod-shaped male screw portion and a female screw portion screwed to the male screw portion, a connecting member connecting the leg portion to the support portion, and rotation of the support portion around the male screw portion. A rotation blocking member for blocking, and the rotation blocking member is provided on the main body portion fixed to the one of the support portion and the leg portion by the connecting member, and the other of the body portion Having a first through hole and a pin inserted into the other second through hole That.

この構成において、一方の第1貫通孔および一方の第2貫通孔には、接続部材の雄ねじ部が挿入されており、雄ねじ部に雌ねじ部が螺合されることによって、支持部に脚部が接続されている。また、他方の第1貫通孔および他方の第2貫通孔には、回動阻止部材のピンが挿入されており、これにより、支持部は、脚部に対して雄ねじ部を中心とする回動が阻止されている。回動阻止部材のピンが設けられた本体部は、支持部および脚部の一方に接続部材で固定されているので、ピンは他方の第1貫通孔および他方の第2貫通孔から脱落し難い。なお、第1貫通孔および第2貫通孔は、それぞれ少なくとも2つずつ形成されていればよく、それぞれ2つに限定するものではない。   In this configuration, the male threaded portion of the connecting member is inserted into the first through hole and the second through hole, and the female threaded portion is screwed into the male threaded portion, so that the leg portion is supported by the supporting portion. It is connected. Further, a pin of a rotation preventing member is inserted into the other first through hole and the other second through hole, whereby the support portion rotates around the male screw portion with respect to the leg portion. Is blocked. Since the main body portion provided with the pin of the rotation preventing member is fixed to one of the support portion and the leg portion with the connecting member, the pin is difficult to drop off from the other first through hole and the other second through hole. . The first through hole and the second through hole only need to be formed at least two each, and are not limited to two.

この構成では、他方の第1貫通孔および他方の第2貫通孔には、回動阻止部材のピンが挿入されるので、雄ねじ部を挿入する必要がない。したがって、雄ねじ部を雌ねじ部に螺合する手間を省くことができ、支持台を短時間で簡単に組み立てることができる。   In this configuration, since the pin of the rotation preventing member is inserted into the other first through hole and the other second through hole, it is not necessary to insert the male screw portion. Therefore, the trouble of screwing the male screw portion into the female screw portion can be saved, and the support base can be easily assembled in a short time.

本発明の他の特徴は、2つの前記第1貫通孔の組を第1組とし、2つの前記第2貫通孔の組を第2組としたとき、前記第1組および前記第2組の一方は、他方に対して異なる高さで対応可能なように上下方向にずらして複数設けられていることにある。   Another feature of the present invention is that when the set of two first through holes is a first set and the set of two second through holes is a second set, the first set and the second set One is that a plurality is provided so as to be shifted in the vertical direction so as to correspond to the other at different heights.

この構成では、支持部の高さを調整することができる。例えば、支持部に第1組が複数設けられている場合には、脚部に設けられた第2組を複数の第1組から選択した1つに対応させることによって、支持部の高さを調整することができる。一方、脚部に第2組が複数設けられている場合には、支持部に設けられた第1組を複数の第2組から選択した1つに対応させることによって、支持部の高さを調整することができる。また、この構成では、上記特許文献1に開示された先行技術に比べて接続部材の数を半分にすることができるので、高さ調整作業の作業負担を大幅に軽減できる。   In this configuration, the height of the support portion can be adjusted. For example, in the case where a plurality of first sets are provided in the support portion, the height of the support portion is increased by making the second set provided in the leg portion correspond to one selected from the plurality of first sets. Can be adjusted. On the other hand, when a plurality of second sets are provided on the leg portion, the height of the support portion is increased by making the first set provided on the support portion correspond to one selected from the plurality of second sets. Can be adjusted. Also, with this configuration, the number of connecting members can be halved compared to the prior art disclosed in Patent Document 1, so that the work load of height adjustment work can be greatly reduced.

本発明の他の特徴は、前記本体部は、前記雄ねじ部が挿通される貫通孔を有しており、前記雄ねじ部は、前記本体部に当接される頭部を有していることにある。   Another feature of the present invention is that the main body portion has a through hole through which the male screw portion is inserted, and the male screw portion has a head portion that comes into contact with the main body portion. is there.

この構成では、雄ねじ部の頭部で本体部を支持部および脚部の一方に押し付けて固定することができる。   In this configuration, the main body portion can be pressed and fixed to one of the support portion and the leg portion with the head portion of the male screw portion.

本発明の他の特徴は、上側の前記第1貫通孔の高さにおける前記支持部と前記脚部との隙間幅を上側隙間幅とし、下側の前記第1貫通孔の高さにおける前記支持部と前記脚部との隙間幅を下側隙間幅としたとき、前記上側隙間幅が前記下側隙間幅よりも広いときには、上側の前記第1貫通孔および上側の前記第2貫通孔に前記雄ねじ部が挿入され、前記下側隙間幅が前記上側隙間幅よりも広いときには、下側の前記第1貫通孔および下側の前記第2貫通孔に前記雄ねじ部が挿入されることにある。   Another feature of the present invention is that the gap width between the support portion and the leg portion at the height of the upper first through hole is the upper gap width, and the support is at the height of the lower first through hole. When the gap width between the portion and the leg portion is the lower gap width, when the upper gap width is wider than the lower gap width, the upper first through hole and the upper second through hole When the male screw portion is inserted and the lower gap width is wider than the upper gap width, the male screw portion is inserted into the lower first through hole and the lower second through hole.

この構成では、上側隙間幅と下側隙間幅とを比較して、上側隙間幅が広いときには、雄ねじ部が上側に配置されるとともにピンが下側に配置される。一方、下側隙間幅が広いときには、雄ねじ部が下側に配置されるとともにピンが上側に配置される。つまり、隙間幅が広い側では、接続部材によって支持部に脚部が密着されて接続される。したがって、支持部と脚部との隙間を効果的に解消することができる。   In this configuration, when the upper gap width is compared with the lower gap width, when the upper gap width is wide, the male screw portion is arranged on the upper side and the pin is arranged on the lower side. On the other hand, when the lower gap width is wide, the male screw portion is disposed on the lower side and the pin is disposed on the upper side. That is, on the side where the gap width is wide, the legs are brought into close contact with and connected to the support portion by the connection member. Therefore, the gap between the support portion and the leg portion can be effectively eliminated.

上記目的を達成するため、本発明の特徴は、上下方向に間隔を隔てて水平方向に向けて設けられた2つの第1貫通孔を有し、支持対象を支持する支持部と、2つの前記第1貫通孔のそれぞれに対応する2つの第2貫通孔を有し、前記支持部の荷重を受ける脚部と、一方の前記第1貫通孔および一方の前記第2貫通孔に挿入される棒状の雄ねじ部と前記雄ねじ部に螺合される雌ねじ部とを有し、前記支持部に前記脚部を接続する接続部材とを備える支持台において、前記雄ねじ部を中心とする前記支持部の回動を阻止するための回動阻止部材であって、前記支持部および前記脚部の一方に対して前記接続部材で固定される本体部と、前記本体部に設けられ、他方の前記第1貫通孔および他方の前記第2貫通孔に挿入されるピンとを有することにある。   In order to achieve the above-described object, the present invention is characterized in that there are two first through holes provided in the horizontal direction with a space in the vertical direction, and a support portion for supporting a support target, Two second through-holes corresponding to each of the first through-holes, a leg portion receiving the load of the support portion, and a rod shape inserted into one of the first through-holes and one of the second through-holes And a connecting member for connecting the leg portion to the support portion. The support portion includes a male screw portion and a female screw portion screwed into the male screw portion. A rotation preventing member for preventing movement, a main body portion fixed to the one of the support portion and the leg portion by the connecting member, and provided in the main body portion, the other first penetration Having a hole and a pin inserted into the other second through hole That.

支持台において、一方の第1貫通孔および一方の第2貫通孔には、接続部材の雄ねじ部が挿入されており、雄ねじ部に雌ねじ部が螺合されることによって、支持部に脚部が接続されている。回動阻止部材のピンは、他方の第1貫通孔および他方の第2貫通孔に挿入される。これにより、雄ねじ部を中心とする支持部の回動を阻止できる。回動阻止部材のピンが設けられた本体部は、支持部および脚部の一方に接続部材で固定されるので、ピンは他方の第1貫通孔および他方の第2貫通孔から脱落し難い。   In the support base, the male threaded portion of the connecting member is inserted into the first through hole and the second through hole, and the female threaded portion is screwed into the male threaded portion, so that the leg portion is formed in the supporting portion. It is connected. The pin of the rotation preventing member is inserted into the other first through hole and the other second through hole. Thereby, rotation of the support part centering on the external thread part can be prevented. Since the main body portion provided with the pin of the rotation preventing member is fixed to one of the support portion and the leg portion by the connecting member, the pin is difficult to drop off from the other first through hole and the other second through hole.

また、支持台の工場出荷時に、他方の第1貫通孔および他方の第2貫通孔に雄ねじ部が挿入されている場合でも、長期の使用により雄ねじ部が緩んで脱落することがある。この場合には、脱落した雄ねじ部に代えて回動阻止部材を用いることによって、支持台を短時間で簡単に修復することができる。   Even when the male screw part is inserted into the other first through hole and the other second through hole at the time of shipment of the support base from the factory, the male screw part may be loosened and fall off due to long-term use. In this case, the support base can be easily repaired in a short time by using the rotation blocking member instead of the dropped male screw portion.

本発明の他の特徴は、前記ピンは、他方の前記第1貫通孔および他方の前記第2貫通孔のそれぞれの内側に配置される第1部分と、前記第1部分の先端部から先方に延びて設けられた第2部分とを有しており、前記第2部分の直径は、前記第1部分の直径よりも小さくされていることにある。   According to another feature of the present invention, the pin includes a first part disposed inside each of the other first through hole and the other second through hole, and a tip portion of the first part. And a second portion that extends and the diameter of the second portion is smaller than the diameter of the first portion.

この構成では、第2部分の直径は第1部分の直径よりも小さくされているので、ピンを第1貫通孔および第2貫通孔に挿通させる際には、小径の第2部分をガイドとして用いて容易に挿通させることができる。したがって、第1部分の外面と第1貫通孔および第2貫通孔のそれぞれの内面との隙間の幅を狭くすることが可能となり、この隙間によるピンのがたつきを抑制できる。   In this configuration, since the diameter of the second portion is smaller than the diameter of the first portion, the second portion having a small diameter is used as a guide when the pin is inserted into the first through hole and the second through hole. Can be easily inserted. Therefore, it is possible to reduce the width of the gap between the outer surface of the first portion and the inner surfaces of the first through hole and the second through hole, and the rattling of the pin due to the gap can be suppressed.

本発明の他の特徴は、前記本体部は、前記雄ねじ部が挿通される貫通孔を有しており、前記雄ねじ部は、前記本体部に当接される頭部を有していることにある。   Another feature of the present invention is that the main body portion has a through hole through which the male screw portion is inserted, and the male screw portion has a head portion that comes into contact with the main body portion. is there.

この構成では、雄ねじ部の頭部で本体部を支持部および脚部の一方に押し付けて固定することができる。   In this configuration, the main body portion can be pressed and fixed to one of the support portion and the leg portion with the head portion of the male screw portion.

本発明の他の特徴は、上記回動阻止部材の製造方法であって、(a)一定厚さの金属製の板材を加工することによってピン挿通孔を有する前記本体部を形成し、(b)金属製の棒材を加工することによって前記ピン挿通孔に挿通されるピン本体と前記本体部の一方面に当接される当接部とを有する前記ピンを形成し、(c)前記本体部の一方面側から前記ピン挿通孔に前記ピン本体を挿通させるとともに、前記当接部を前記本体部の一方面に溶接することにある。   Another feature of the present invention is a method of manufacturing the rotation preventing member, wherein (a) the body portion having a pin insertion hole is formed by processing a metal plate having a constant thickness; ) Forming a pin having a pin main body inserted into the pin insertion hole and an abutting portion abutting against one surface of the main body by processing a metal bar; and (c) the main body The pin main body is inserted into the pin insertion hole from one surface side of the portion, and the contact portion is welded to one surface of the main body portion.

この構成では、金属製の板材と金属製の棒材とによって、回動阻止部材を簡単に製造することができる。   In this configuration, the rotation preventing member can be easily manufactured by using a metal plate and a metal bar.

本発明の他の特徴は、前記工程(b)では、前記本体部の一方面に当接される当接部の当接面を前記ピン本体に対して垂直に形成することにある。   Another feature of the present invention is that, in the step (b), a contact surface of a contact portion that is in contact with one surface of the body portion is formed perpendicular to the pin body.

A circular pin insertion hole 66 through which the pin 62 is inserted is formed at the center in the front-rear direction at the lower portion of the main body 60. Further, as shown in FIG. 4A, around the through hole 64 on one surface (left side surface) 60e of the main body portion 60, a letter “up” indicating an appropriate direction of the main body portion 60 and a male screw portion 44 are provided. An arrow indicating the direction in which the screw is turned, and letters “Shimal” and “Yulm” indicating the effect of turning the male screw portion 44 are described.

図5に示すように、ピン62は、ピン挿通孔66に挿通される円柱状のピン本体68と、ピン本体68の基端部から拡径して設けられた円盤状の当接部70とを有している。ピン本体68は、下側の第1貫通孔24および下側の第2貫通孔40(図3)のそれぞれの内側に配置される円柱状の第1部分68aと、第1部分68aの先端部から先方に延びて設けられた第2部分68bとを有している。第1部分68aの外径は、第1貫通孔24および第2貫通孔40の各内径に対して若干細い隙間嵌めとなる太さに形成されている。また、第2部分68bの外径は、第1部分68aの直径よりも細く形成されているが、雌ネジ部46の内径に対して前記第1部分68aの隙間嵌め(第1貫通孔24および第2貫通孔40に対する各隙間)と同じ隙間嵌め(隙間)となる太さに形成されている。   As shown in FIG. 5, the pin 62 includes a cylindrical pin main body 68 that is inserted into the pin insertion hole 66, and a disk-shaped contact portion 70 that is provided with a diameter increased from the base end portion of the pin main body 68. have. The pin main body 68 includes a columnar first portion 68a disposed inside each of the lower first through hole 24 and the lower second through hole 40 (FIG. 3), and a tip portion of the first portion 68a. And a second portion 68b provided to extend forward. The outer diameter of the first portion 68 a is formed to a thickness that provides a slightly narrower gap fit to the inner diameters of the first through hole 24 and the second through hole 40. The outer diameter of the second portion 68b is smaller than the diameter of the first portion 68a, but the gap fitting of the first portion 68a with respect to the inner diameter of the female screw portion 46 (the first through hole 24 and Each gap is formed to have the same thickness as the gap fitting (gap).

当接部70には、本体部60の一方面(左側面)60eに当接される当接面70aが形成されており、当接面70aには、溶接の際に溶かされる複数(本実施形態では3つ)の突起74が周方向に一定の角度間隔(本実施形態では120度)を隔てて形成されている。当接面70aは、ピン本体68に対して垂直な平坦面に形成されている。したがって、当接面70aが本体部60の一方面(左側面)60eに当接されて溶接されると、本体部60の他方面(右側面)60fとピン本体68とがなす角度は必然的に90度になる。   The contact portion 70 is formed with an abutment surface 70a that abuts against one surface (left side surface) 60e of the main body 60, and the abutment surface 70a has a plurality of (this embodiment) melted during welding. In the embodiment, three projections 74 are formed at a constant angular interval (120 degrees in the present embodiment) in the circumferential direction. The contact surface 70 a is formed as a flat surface perpendicular to the pin body 68. Therefore, when the contact surface 70a is in contact with and welded to one surface (left side) 60e of the main body 60, the angle formed between the other surface (right side) 60f of the main body 60 and the pin main body 68 is inevitable. It becomes 90 degrees.

(回動阻止部材18の製造方法)
図5に示すように、回動阻止部材18を製造する際には、まず、一定厚さの金属製の板材(図示省略)を加工することによって貫通孔64とピン挿通孔66とを有する本体部60を形成する。また、金属製の棒材(図示省略)を加工することによってピン本体68と当接部70とを有するピン62を形成する。続いて、本体部60の一方面60e側からピン挿通孔66にピン本体68を挿通させるとともに、当接部70の当接面70aを本体部60の一方面60eに当接させる。その後、当接部70の当接面70aと本体部60の一方面60eとをプロジェクション溶接により接合する。プロジェクション溶接では、当接面70aに設けられた複数の突起74が溶かされるので、当接部70の当接面70aを本体部60の一方面60eに隙間なく接合できる。
(Manufacturing method of the rotation prevention member 18)
As shown in FIG. 5, when manufacturing the rotation preventing member 18, first, a main body having a through hole 64 and a pin insertion hole 66 by processing a metal plate (not shown) having a certain thickness. A portion 60 is formed. Moreover, the pin 62 which has the pin main body 68 and the contact part 70 is formed by processing metal bar material (illustration omitted). Subsequently, the pin main body 68 is inserted into the pin insertion hole 66 from the one surface 60 e side of the main body portion 60, and the contact surface 70 a of the contact portion 70 is brought into contact with the one surface 60 e of the main body portion 60. Then, the contact surface 70a of the contact part 70 and the one surface 60e of the main-body part 60 are joined by projection welding. In projection welding, the plurality of protrusions 74 provided on the contact surface 70a are melted, so that the contact surface 70a of the contact portion 70 can be joined to the one surface 60e of the main body 60 without any gap.

(支持台10の組み立て方法)
図6は、支持部12に脚部14aを固定する方法を示す断面図である。図1に示す支持台10を組み立てる際には、まず、支持部12と2つの脚部14a,14bとを別々に準備し、2つの脚部14a,14bを連結部32で連結する。2つの脚部14a,14bを連結部32で連結したとき、2本の支柱30,30は、鉛直方向に延びて互いに平行になることが望ましい。しかし、現実には、様々な条件により、2本の支柱30,30は、上方に向かうにつれて左右方向中央側に傾く傾向がある。
(Assembly method of support base 10)
FIG. 6 is a cross-sectional view showing a method for fixing the leg portion 14 a to the support portion 12. When assembling the support base 10 shown in FIG. 1, first, the support portion 12 and the two leg portions 14 a and 14 b are separately prepared, and the two leg portions 14 a and 14 b are connected by the connecting portion 32. When the two leg portions 14a and 14b are connected by the connecting portion 32, it is desirable that the two support columns 30 and 30 extend in the vertical direction and become parallel to each other. However, in reality, due to various conditions, the two support columns 30 and 30 tend to tilt toward the center in the left-right direction as they go upward.

2つの脚部14a,14bの連結が完了すると、図6に示すように、支持部12を構成する垂下部22aの左右方向の内側(右側)に脚部14aの支柱30を配置する。上述のように、支柱30は、上方に向かうにつれて左右方向中央側(右側)に傾いているので、支持部12と脚部14aとの間に生じる隙間76の幅は、上方に向かうにつれて広くなる。したがって、上側の第1貫通孔24の高さにおける隙間76の幅を上側隙間幅W1とし、下側の第1貫通孔24の高さにおける隙間76の幅を下側隙間幅W2としたとき、上側隙間幅W1は下側隙間幅W2よりも広くなる。   When the connection between the two leg portions 14a and 14b is completed, the support column 30 of the leg portion 14a is disposed on the inner side (right side) of the hanging portion 22a constituting the support portion 12 in the left-right direction, as shown in FIG. As described above, since the support column 30 is inclined toward the center in the left-right direction (right side) as it goes upward, the width of the gap 76 generated between the support part 12 and the leg part 14a becomes wider as it goes upward. . Therefore, when the width of the gap 76 at the height of the upper first through hole 24 is the upper gap width W1, and the width of the gap 76 at the height of the lower first through hole 24 is the lower gap width W2, The upper gap width W1 is wider than the lower gap width W2.

支持部12に対する脚部14aの位置決めが完了すると、図3に示すように、支持部12に脚部14aを固定する。支持部12に脚部14aを固定する際には、まず、支持部12の側面12aに回動阻止部材18の本体部60を配置するとともに、回動阻止部材18のピン62を下側の第1貫通孔24および下側の第2貫通孔40に挿通させる。ピン62の第2部分68bの直径は、第1部分68aの直径よりも小さくされているので、ピン62(ピン本体68)を下側の第1貫通孔24および下側の第2貫通孔40に挿通させる際には、小径の第2部分68bがガイドとなる。   When the positioning of the leg portion 14a with respect to the support portion 12 is completed, the leg portion 14a is fixed to the support portion 12 as shown in FIG. When fixing the leg portion 14 a to the support portion 12, first, the main body portion 60 of the rotation prevention member 18 is disposed on the side surface 12 a of the support portion 12, and the pin 62 of the rotation prevention member 18 is placed on the lower side. The first through hole 24 and the lower second through hole 40 are inserted. Since the diameter of the second portion 68b of the pin 62 is smaller than the diameter of the first portion 68a, the pin 62 (pin main body 68) is connected to the lower first through hole 24 and the lower second through hole 40. When inserted through the second portion 68b, the second portion 68b having a small diameter serves as a guide.

続いて、回動阻止部材18の貫通孔64、上側の第1貫通孔24および上側の第2貫通孔40に雄ねじ部44を挿入し、この雄ねじ部44を雌ねじ部46に螺合する。すると、雄ねじ部44と雌ねじ部46との締め付け力によって支持部12と脚部14aとが密着されて接続される。このとき、回動阻止部材18の本体部60は、雄ねじ部44の頭部50で支持部12に押し付けられて固定される。   Subsequently, the male screw portion 44 is inserted into the through hole 64 of the rotation blocking member 18, the upper first through hole 24, and the upper second through hole 40, and the male screw portion 44 is screwed into the female screw portion 46. Then, the support part 12 and the leg part 14a are brought into close contact with each other by the tightening force between the male screw part 44 and the female screw part 46. At this time, the main body portion 60 of the rotation preventing member 18 is pressed against the support portion 12 by the head portion 50 of the male screw portion 44 and fixed.

(回動阻止部材18の他の使用方法)
図7は、従来の支持台80に対する回動阻止部材18の使用方法を示す断面図である。図7に示す従来の支持台80は、支持部82と脚部84aとを有しており、支持部82と脚部84aとは、2つの接続部材86,86によって互いに接続されている。この従来の支持台80では、上側の雄ねじ部88を中心とする支持部82の回動が下側の接続部材86によって阻止される。
(Other usage methods of the rotation prevention member 18)
FIG. 7 is a cross-sectional view showing a method of using the rotation preventing member 18 with respect to the conventional support base 80. The conventional support base 80 shown in FIG. 7 has a support portion 82 and a leg portion 84 a, and the support portion 82 and the leg portion 84 a are connected to each other by two connecting members 86 and 86. In this conventional support base 80, the rotation of the support portion 82 around the upper male screw portion 88 is prevented by the lower connection member 86.

図7に示す従来の支持台80において、支持部82の高さを調整する場合には、2つの接続部材86,86を取り外す必要があるが、支持部82の高さを調整した後は、一方(図7では下側)の接続部材86に変えて、上記実施形態の回動阻止部材18が用いられてもよい。この場合には、図7中に二点鎖線で示すように、回動阻止部材18のピン62が、下側の第1貫通孔90および下側の第2貫通孔92に挿通される。また、接続部材86の雄ねじ部88が、回動阻止部材18の貫通孔64、上側の第1貫通孔90および上側の第2貫通孔92に挿通されて、雌ねじ部94に螺合される。   In the conventional support base 80 shown in FIG. 7, when adjusting the height of the support portion 82, it is necessary to remove the two connection members 86, 86, but after adjusting the height of the support portion 82, Instead of the connection member 86 on the one side (lower side in FIG. 7), the rotation preventing member 18 of the above embodiment may be used. In this case, as indicated by a two-dot chain line in FIG. 7, the pin 62 of the rotation preventing member 18 is inserted into the lower first through hole 90 and the lower second through hole 92. The male screw portion 88 of the connection member 86 is inserted into the through hole 64 of the rotation blocking member 18, the upper first through hole 90, and the upper second through hole 92, and is screwed into the female screw portion 94.

このように、従来の支持台80においても、回動阻止部材18を用いることによって、高さ調整作業の作業負担を大幅に軽減することができる。   Thus, also in the conventional support stand 80, by using the rotation prevention member 18, the work burden of the height adjustment work can be greatly reduced.

また、図7に示す従来の支持台80において、2つの接続部材86,86のうち1つが緩んで脱落した場合には、脱落した接続部材86に代えて回動阻止部材18が用いられてもよい。この場合は、回動阻止部材18によって支持台80を簡単に修復することができる。   Further, in the conventional support base 80 shown in FIG. 7, when one of the two connection members 86, 86 is loosened and dropped out, the rotation preventing member 18 may be used instead of the dropped connection member 86. Good. In this case, the support base 80 can be easily repaired by the rotation blocking member 18.

(効果)
本実施形態によれば、上記構成により以下の各効果を奏することができる。すなわち、図3に示すように、下側の第1貫通孔24および下側の第2貫通孔40には、雄ねじ部44を挿入する必要がなく、雄ねじ部44を雌ねじ部46に螺合する手間を省くことができるので、支持台10を短時間で簡単に組み立てることができる。
(effect)
According to the present embodiment, the following effects can be achieved by the above configuration. That is, as shown in FIG. 3, it is not necessary to insert the male screw portion 44 into the lower first through hole 24 and the lower second through hole 40, and the male screw portion 44 is screwed into the female screw portion 46. Since labor can be saved, the support base 10 can be easily assembled in a short time.

図3に示すように、回動阻止部材18におけるピン62が設けられた本体部60は、接続部材16で支持部12に固定されるので、ピン62は第1貫通孔24および第2貫通孔40から脱落し難い。   As shown in FIG. 3, the main body portion 60 provided with the pin 62 in the rotation preventing member 18 is fixed to the support portion 12 by the connecting member 16, so that the pin 62 includes the first through hole 24 and the second through hole. It is difficult to drop off 40.

上述のように、ピン62を第1貫通孔24および第2貫通孔40に挿通させる際には、小径の第2部分68bをガイドとして用いて容易に挿通させることができる。したがって、第1部分68aの外面と第1貫通孔24および第2貫通孔40のそれぞれの内面との隙間の幅を狭くすることが可能となり、この隙間によるピン62のがたつきを抑制できる。   As described above, when the pin 62 is inserted into the first through hole 24 and the second through hole 40, the second portion 68b having a small diameter can be easily inserted. Therefore, it is possible to reduce the width of the gap between the outer surface of the first portion 68a and the inner surfaces of the first through hole 24 and the second through hole 40, and the rattling of the pin 62 due to this gap can be suppressed.

第2部分68bの外径は、雌ネジ部46の内径に対して第1部分68aの隙間嵌めと同じ隙間嵌め(隙間)となる太さに形成されているため、第1部分68aおよび第2部分68bを第1貫通孔24、第2貫通孔40および雌ねじ部46の各内周面に同時に接触させることができ、接触面圧を分散して各接触部分の損傷を防止することができる。   Since the outer diameter of the second portion 68b is formed to have the same gap fit (gap) as the gap fit of the first portion 68a with respect to the inner diameter of the female screw portion 46, the first portion 68a and the second portion 68b. The portion 68b can be brought into contact with the inner peripheral surfaces of the first through hole 24, the second through hole 40, and the female screw portion 46 at the same time, and the contact surface pressure can be dispersed to prevent the contact portions from being damaged.

図3に示すように、2つの第1貫通孔24の組を第1組26とし、2つの第2貫通孔40の組を第2組42としたとき、第1組26は、第2組42に対して異なる高さで対応可能なように上下方向にずらして複数設けられている(図2)。したがって、複数の第1組26から選択した1つに第2組42を対応させることによって、支持部12の高さを調整することができる。   As shown in FIG. 3, when the set of two first through holes 24 is a first set 26 and the set of two second through holes 40 is a second set 42, the first set 26 is a second set. A plurality are provided so as to be shifted in the vertical direction so as to correspond to different heights with respect to 42 (FIG. 2). Therefore, the height of the support portion 12 can be adjusted by making the second set 42 correspond to one selected from the plurality of first sets 26.

図6に示すように、上側隙間幅W1と下側隙間幅W2とを比較して、広い方の上側隙間幅W1に対応する第1貫通孔24および第2貫通孔40には、雄ねじ部44が挿入される。そして、この雄ねじ部44が雌ねじ部46に螺合されることによって、支持部12に脚部14aが接続される。したがって、支持部12と脚部14aとを確実に密着させることができ、支持部12と脚部14aとの隙間76を効果的に解消することができる。   As shown in FIG. 6, when comparing the upper gap width W <b> 1 and the lower gap width W <b> 2, the first through hole 24 and the second through hole 40 corresponding to the wider upper gap width W <b> 1 include the male screw portion 44. Is inserted. Then, the male screw portion 44 is screwed into the female screw portion 46, whereby the leg portion 14 a is connected to the support portion 12. Therefore, the support part 12 and the leg part 14a can be made to contact | adhere reliably, and the clearance gap 76 between the support part 12 and the leg part 14a can be eliminated effectively.

図3に示すように、回動阻止部材18の本体部60は、雄ねじ部44が挿通される貫通孔64を有しており、雄ねじ部44は、本体部60に当接される頭部50を有しているので、雄ねじ部44の頭部50で本体部60を支持部12に押し付けて固定することができる。   As shown in FIG. 3, the main body portion 60 of the rotation preventing member 18 has a through hole 64 through which the male screw portion 44 is inserted, and the male screw portion 44 is a head 50 that contacts the main body portion 60. Therefore, the main body 60 can be pressed against the support 12 with the head 50 of the male screw portion 44 and fixed.

図5に示すように、金属製の板材からなる本体部60と、金属製の棒材からなるピン62とよって、回動阻止部材18を簡単に製造することができる。また、当接部70の当接面70aをピン本体68に対して垂直に形成しているので、当接面70aを本体部60の一方面60eに溶接するだけで、ピン本体68を本体部60の他方面60fに対して垂直に配置することができる。   As shown in FIG. 5, the rotation preventing member 18 can be easily manufactured by the main body 60 made of a metal plate and the pins 62 made of a metal bar. Further, since the contact surface 70a of the contact portion 70 is formed perpendicular to the pin main body 68, the pin main body 68 can be attached to the main body portion simply by welding the contact surface 70a to the one surface 60e of the main body portion 60. 60 can be disposed perpendicular to the other surface 60f.

(Modification)
In carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention. For example, in the above embodiment, the support base 10 shown in FIG. 1 is configured as a desk that supports an object (textbook, notebook, etc.), but the support base may be configured as a chair (not shown) that supports a person. Good.

図3に示すように、上記実施形態では、2つの雌ねじ部46,46が、脚部14aを構成する支柱30の上端部30aに溶接されているが、雌ねじ部46,46は、脚部14aから独立して設けられてもよい。また、ピン62が挿入される側の雌ねじ部46は省略されてもよい。   As shown in FIG. 3, in the above embodiment, the two female screw portions 46, 46 are welded to the upper end portion 30a of the support column 30 constituting the leg portion 14a, but the female screw portions 46, 46 are connected to the leg portion 14a. May be provided independently. Further, the female screw portion 46 on the side where the pin 62 is inserted may be omitted.

図3に示すように、上記実施形態では、回動阻止部材18の本体部60に貫通孔64が形成されているが、貫通孔64に代えて、U字状またはV字状の凹部(図示省略)が本体部60の外周縁に形成されてもよい。この場合でも、雄ねじ本体48の周囲に凹部を配置することによって、頭部50で本体部60を支持部12に押し付けて固定することができる。   As shown in FIG. 3, in the above embodiment, the through hole 64 is formed in the main body portion 60 of the rotation preventing member 18, but instead of the through hole 64, a U-shaped or V-shaped concave portion (illustration is shown). (Omitted) may be formed on the outer peripheral edge of the main body 60. Even in this case, by disposing the concave portion around the male screw main body 48, the main body portion 60 can be pressed against the support portion 12 and fixed by the head portion 50.

図5に示すように、上記実施形態では、ピン本体68が、外径の異なる第1部分68aおよび第2部分68bを有する棒状に構成されているが、ピン本体68は、全長にわたって一定の外径を有する棒状に構成されてもよいし、先端に向かうにつれて外径が徐々に小さくなる棒状に構成されてもよい。   As shown in FIG. 5, in the above embodiment, the pin main body 68 is formed in a rod shape having a first portion 68a and a second portion 68b having different outer diameters. It may be configured in a rod shape having a diameter, or may be configured in a rod shape in which the outer diameter gradually decreases toward the tip.

また、ピン本体68は、外径の異なる第1部分68aおよび第2部分68bを有する場合においては、第2部分68bの外径を雌ネジ部46の内径に対して第1部分68aの隙間嵌めより大きな隙間の隙間嵌めとなる太さに形成することで、雌ねじ部46の内周面への接触を回避して雌ネジ部46の損傷を防止することもできる。また、ピン本体68は、第2部分68bの外径を雌ネジ部46の内径に対して第1部分68aの隙間嵌めより小さな隙間の隙間嵌めとなる太さに形成することで、第1貫通孔24および第2貫通孔40の各内周面への接触を回避して第1貫通孔24および第2貫通孔40の損傷を防止することもできる。   Further, when the pin main body 68 has the first portion 68a and the second portion 68b having different outer diameters, the outer diameter of the second portion 68b is fitted into the gap of the first portion 68a with respect to the inner diameter of the female screw portion 46. By forming the gap so as to fit into a larger gap, contact with the inner peripheral surface of the female screw portion 46 can be avoided and damage to the female screw portion 46 can be prevented. In addition, the pin body 68 is formed so that the outer diameter of the second portion 68b is smaller than that of the first portion 68a with respect to the inner diameter of the female screw portion 46, so that the gap fit is smaller than the first fit. It is also possible to prevent the first through hole 24 and the second through hole 40 from being damaged by avoiding contact with the inner peripheral surfaces of the hole 24 and the second through hole 40.

図3に示す回動阻止部材18は、上下が逆に配置されてもよい。つまり、下側の第1貫通孔24と下側の第2貫通孔40とに接続部材16の雄ねじ部44が挿通されるとともに、上側の第1貫通孔24と上側の第2貫通孔40とに回動阻止部材18のピン62が挿通されてもよい。特に、下側隙間幅W2が上側隙間幅W1よりも広くなっている場合には、回動阻止部材18の上下を逆にすることによって、支持部12と脚部14aとの隙間76を効果的に解消することができる。   The rotation preventing member 18 shown in FIG. 3 may be arranged upside down. That is, the male screw portion 44 of the connecting member 16 is inserted into the lower first through hole 24 and the lower second through hole 40, and the upper first through hole 24 and the upper second through hole 40 are The pin 62 of the rotation preventing member 18 may be inserted through the pin. In particular, when the lower gap width W2 is wider than the upper gap width W1, the gap 76 between the support portion 12 and the leg portion 14a is effectively reduced by turning the rotation prevention member 18 upside down. Can be resolved.

図3に示すように、上記実施形態では、回動阻止部材18の本体部60が接続部材16で支持部12に固定されているが、この本体部60は接続部材16で脚部14aに固定されてもよい。この場合には、脚部14aの側に回動阻止部材18が配置されるので、雌ねじ部46は支持部12の側に配置されることになる。   As shown in FIG. 3, in the above embodiment, the main body portion 60 of the rotation preventing member 18 is fixed to the support portion 12 by the connecting member 16, but the main body portion 60 is fixed to the leg portion 14 a by the connecting member 16. May be. In this case, since the rotation preventing member 18 is disposed on the leg portion 14a side, the female screw portion 46 is disposed on the support portion 12 side.

図3に示すように、上記実施形態では、支持部12に設けられた2つの第1貫通孔24の組である第1組26が上下方向にずらして複数設けられているが、これに代えて、脚部14aに設けられた2つの第2貫通孔40の組である第2組42が上下方向にずらして複数設けられてもよい。   As shown in FIG. 3, in the above embodiment, a plurality of first sets 26, which are sets of two first through holes 24 provided in the support portion 12, are provided while being shifted in the vertical direction. In addition, a plurality of second sets 42, which are sets of two second through holes 40 provided in the leg portion 14a, may be provided while being shifted in the vertical direction.
