Description

卓球台Table tennis table
　本発明は、卓球の練習に主として用いられる卓球台に関する。 The present invention relates to a table tennis table mainly used for table tennis practice.
　一般に、卓球台として、国際規格など公認規格または公式規格のサイズのものが試合用および練習用に使用されている。また、家庭などでの練習用には、それよりも小さいサイズのものが使用されている。国際規格サイズの卓球台としては、国際卓球連盟（ＩＴＴＦ）が公認する長さ２７４０ｍｍ、幅１５２５ｍｍ、高さ７６０ｍｍのものが使用されている。 Generally, as a table tennis table, a size of an official standard or an official standard such as an international standard is used for game and practice. In addition, smaller ones are used for practice at home and the like. As a table tennis table of the international standard size, the one having a length of 2740 mm, a width of 1525 mm and a height of 760 mm, which is approved by the International Table Tennis Federation (ITTF), is used.
　従来において、そのような卓球台として、天板を折り畳み式にして収納スペースを小さくしたものが知られている（特許文献１）。 Conventionally, as such a table tennis table, what made the top plate foldable and made storage space small is known (patent document 1).
　また、天板を３つに分割し、設置場所に応じてサイズを変更可能とした卓球台が提案されている（特許文献２）。 Moreover, the table-top was divided | segmented into three and the table tennis stand which was able to change a size according to an installation place is proposed (patent document 2).
　また、横幅を国際規格サイズの半分に狭めて狭い場所でも使用できる卓球台が提案されている（特許文献３）。 In addition, a table tennis table is proposed which can be used in narrow places by narrowing the width to half of the international standard size (Patent Document 3).

　体育館などの公共施設での卓球の試合または練習では、国際規格サイズの卓球台を使用することにスペース上の問題はない。しかし、家庭などのように十分にスペースを取れない狭い場所では、国際規格サイズの卓球台を使用しての練習は通常困難である。 There are no space problems in using a table tennis table of international standard size in a table tennis match or practice in public facilities such as a gymnasium. However, in narrow places where there is not enough space, such as at home, practicing using a table tennis table of international standard size is usually difficult.
　例えば、上に記載した特許文献１の卓球台では、使用しないときの収納スペースは小さくて済むが、使用するときは国際規格サイズそのものであるため、通常は設置が難しい。　　　 For example, in the table tennis table of patent document 1 described above, although the storage space when not using may be small, since it is international standard size itself when using, installation is usually difficult.
　また、上に記載した特許文献２の卓球台では、３分割された１つの天板は長さ９００ｍｍ、幅１０２０ｍｍであり、これらの２つを用いて１８００ｍｍ×１０２０ｍｍの卓球台とした場合でも、かなりの設置スペースを必要とする。使用しないときに３つの天板を有効活用することは容易ではない。 In addition, in the table tennis table of Patent Document 2 described above, one top plate divided into three is 900 mm long and 1020 mm wide, and even if it is a table tennis table of 1800 mm × 1020 mm using these two, Requires considerable installation space. It is not easy to make effective use of the three tops when not in use.
　また、上に記載した特許文献３の卓球台では、横幅が国際規格サイズの半分になっているので設置スペースは半分になるが、それでもかなりの設置スペースが必要である。また、卓球台を使用しない場合でもその保管に設置面積と同じスペースを必要とする。 Further, in the table tennis table of Patent Document 3 described above, since the width is half of the international standard size, the installation space is halved, but still a considerable installation space is required. In addition, even if you do not use the table tennis table, it requires the same space as the installation area for its storage.
　そして、特許文献２、３を含む従来の小型サイズの卓球台では、国際規格サイズの卓球台を使用した場合と同等の本格的な練習ができないという問題がある。 And in the conventional small size table tennis table containing patent documents 2 and 3, there is a problem that a full-scale exercise equivalent to a case where a table tennis table of international standard size is used can not be performed.
　つまり、例えば特許文献２の卓球台では、長さが国際規格サイズよりも短いので、打った卓球ボールが相手のコートに入ったかどうかを正確に見極めることができず、本格的な練習は行い得ない。 That is, for example, in the table tennis table of Patent Document 2, since the length is shorter than the international standard size, it is not possible to accurately determine whether the hit table tennis ball has entered the opponent's court and full-scale practice can be performed. Absent.
　特許文献３の卓球台では、長さは国際規格サイズと同じであるので、ストレートの練習ではよいが、クロスでの本格的な練習は行い得ない。 In the table tennis table of Patent Document 3, since the length is the same as the international standard size, although it is good in straight practice, full-scale practice in the cross can not be performed.
　本発明は、上述の問題に鑑みてなされたもので、設置スペースが少なくて済み、しかもストレートおよびクロスの両方で国際規格などの公認規格サイズの卓球台と同等の本格的な練習を行うことのできる卓球台を提供することを目的とする。 The present invention has been made in view of the above-mentioned problems, requires less installation space, and performs full-scale practice equivalent to a certified standard size table tennis table such as an international standard in both straight and cross. The purpose is to provide a table tennis table that can be played.
　本発明に係る卓球台は、卓球の練習に主として用いられる卓球台であって、天板部および前記天板部を支持する脚部とを備えた２つの台部材と、ネット部材と、を有し、２つの前記台部材の前記天板部は、幅が公認規格の幅の２分の１以下であってかつ互いに同じ寸法であり、長手方向における一方の端部に当該天板部の幅方向に沿った端縁部が、長手方向における他方の端部に当該天板部の幅方向に対して傾斜した傾斜縁部が、それぞれ形成されており、２つの前記天板部をそれぞれの前記傾斜縁部を互いに突き合わせて接触した状態で長手方向に一列になるように配置したときに、その全体の長さが前記公認規格の長さに一致するようになっている。 The table tennis table according to the present invention is a table tennis table mainly used for practicing table tennis, and has two base members including a top plate and legs supporting the top plate, and a net member And the top plate portions of the two base members have a width equal to or less than a half of the width of the official standard and have the same dimensions, and the width of the top plate portion at one end in the longitudinal direction An edge along the direction is formed at the other end in the longitudinal direction with an inclined edge which is inclined with respect to the width direction of the top plate, respectively, and When the beveled edges are arranged in a longitudinal row with the butt ends in contact with one another, the overall length is adapted to the length of the said official standard.
　好ましくは、２つの前記台部材は、それぞれ、前記天板部が前記脚部に対して着脱可能であってかつ表裏反転させることが可能となっている。 Preferably, in the two base members, the top plate can be detachably attached to the leg and can be turned upside down.
　本発明によると、設置スペースが少なくて済み、しかもストレートおよびクロスの両方で公認規格サイズの卓球台と同等の本格的な練習を行うことのできる卓球台を提供することができる。 According to the present invention, it is possible to provide a table tennis table which requires less installation space and can perform a full-scale exercise equivalent to a certified standard size table tennis table in both straight and cross.

〔第一の実施形態の卓球台〕
　図１および図２において、卓球台１は、卓球の練習に主として用いられるものであり、互いに同じ形状の２つの台部材３、４、およびネット部材５を有する。 [Ping Pong Table of the First Embodiment]
In FIG. 1 and FIG. 2, the table tennis table 1 is mainly used for table tennis practice, and has two base members 3 and 4 and a net member 5 which have the same shape.
　図２に示すように、台部材３、４は、天板部１１、２１、および、天板部１１、２１をそれぞれ支持する脚部１２、２２を備える。本実施形態において、天板部１１、２１、および脚部１２、２２は、それぞれ互いに同じ構造であって同じ形状寸法である。 As shown in FIG. 2, the base members 3 and 4 are provided with the top plates 11 and 21 and the legs 12 and 22 that respectively support the top plates 11 and 21. In the present embodiment, the top plates 11 and 21 and the legs 12 and 22 have the same structure and the same shape and size, respectively.
　図３～図６に示すように、２つの天板部１１、２１は、長手方向に沿って延びる互いに平行な長辺縁部１１ａ，１１ｂおよび長辺縁部２１ａ，２１ｂを有し、長辺縁部１１ａと１１ｂ、長辺縁部２１ａと２１ｂのそれぞれの間隔が、天板部１１、２１の幅Ｗ２となっている。 As shown in FIGS. 3 to 6, the two top plates 11 and 21 have parallel long side edges 11a and 11b and long side edges 21a and 21b extending along the longitudinal direction, and the long sides The distance between the edge portions 11 a and 11 b and the long side edge portions 21 a and 21 b is the width W 2 of the top plate portions 11 and 21.
　天板部１１、２１の幅Ｗ２は、互いに同じ寸法であり、公認規格としての国際規格の幅Ｗ１の２分の１以下、本実施形態では国際規格サイズの４分の１以下となっている。国際規格の幅Ｗ１は１５２５ｍｍであるので、天板部１１、２１の幅Ｗ２は、１５２５÷４で、約３８．１ｍｍ、またはそれよりも狭いということである。具体的には、第一の実施形態の図１～図６に示した例では、幅Ｗ２は３０ｍｍである。 The widths W2 of the top plate portions 11 and 21 are equal to each other, and are less than or equal to a half of the width W1 of the international standard as the official standard, and less than or equal to 1⁄4 of the international standard size in this embodiment. . Since the width W1 of the international standard is 1525 mm, the width W2 of the top plate parts 11 and 21 is 1525/4 and about 38.1 mm or narrower. Specifically, in the example shown in FIGS. 1 to 6 of the first embodiment, the width W2 is 30 mm.
　そして、天板部１１、２１は、長手方向における一方の端部に当該天板部１１、２１の幅方向に沿った端縁部１１ｃ，２１ｃが、長手方向における他方の端部に当該天板部１１、２１の幅方向に対して角度α１（度）だけ傾斜した傾斜縁部１１ｄ，２１ｄが、それぞれ形成されている。 And the top plate parts 11 and 21 have the edge parts 11c and 21c along the width direction of the top plate parts 11 and 21 at one end in the longitudinal direction and the top plate at the other end in the longitudinal direction. Inclined edge portions 11d and 21d are formed at an angle α1 (degree) with respect to the width direction of the portions 11 and 21, respectively.
　２つの天板部１１、２１の傾斜縁部１１ｄ，２１ｄの角度α１は同じであるので、傾斜縁部１１ｄ，２１ｄを互いに突き合わせて接触した状態で、図１および図６に示すように長手方向に一列になるように配置したときに、その全体の長さＬ１が国際規格の長さＬ１に一致するようになっている。 Since the angle α1 of the inclined edges 11d and 21d of the two top plates 11 and 21 is the same, as shown in FIGS. 1 and 6, the longitudinal direction is obtained with the inclined edges 11d and 21d in contact with each other. When arranged in a row, the entire length L1 is made to match the length L1 of the international standard.
　このような天板部１１、２１は、木材、合板、プラスチックなどの材料からなる適当な厚さ寸法、例えば１５～２５ｍｍ程度の厚さの長尺の板材を用いて形成することが可能である。 Such top plate portions 11 and 21 can be formed using a plate material having a suitable thickness dimension, for example, a thickness of about 15 to 25 mm, made of a material such as wood, plywood, or plastic. .
　図４および図５において、脚部１２、２２は、それぞれ、４つのスタンド３１ａ～ｄ、２つの長側板３２ａ，ｂ、２つの短側板３３ａ，ｂからなる。長側板３２ａ，ｂおよび短側板３３ａ，ｂは、ネジまたは接着剤などによって互いに連結されてほぼ矩形の枠形状に形成され、その４ヵ所のコーナー部分にスタンド３１ａ～ｄがネジまたは接着剤などによって固定される。 In FIGS. 4 and 5, the legs 12 and 22 are respectively composed of four stands 31a to 31d, two long side plates 32a and 32b, and two short side plates 33a and 33b. The long side plates 32a and 32b and the short side plates 33a and 33b are connected to each other by a screw or an adhesive to form a substantially rectangular frame shape, and four corner portions of the stands 31a to 31d are formed by screws or an adhesive or the like. It is fixed.
　長側板３２ａ，ｂの長さは、国際規格の長さＬ１の半分の長さＬ２よりも短く、短側板３３ａ，ｂの長さは、天板部１１、２１の幅Ｗ２と同じである。スタンド３１ａ～ｄの長さは、国際規格の卓球台の高さＨ１から天板部１１、２１の厚さを差し引いた寸法である。スタンド３１ａ～ｄとして、その下端部に、クッション部材、滑り止め部材、または高さ調整部材などを設けておいてもよい。 The lengths of the long side plates 32a and 32b are shorter than the half length L2 of the length L1 of the international standard, and the lengths of the short side plates 33a and 33b are the same as the width W2 of the top plate portions 11 and 21. The length of the stands 31a to 31d is a size obtained by subtracting the thickness of the tops 11 and 21 from the height H1 of the international standard table tennis table. As the stands 31a to 31d, a cushion member, a non-slip member, a height adjustment member or the like may be provided at the lower end portion thereof.
　したがって、脚部１２、２２は、平面視において、その長さが天板部１１、２１の短い方の長辺縁部１１ｂ，２１ｂの長さＬ２ｂよりも短く、その幅が天板部１１、２１の幅Ｗ２と同じである。 Therefore, in plan view, the legs 12 and 22 have a length shorter than the length L 2 b of the shorter long side edge 11 b or 21 b of the top 11 or 21, and the width thereof is the top 11 It is the same as the width W2 of 21.
　本実施形態において、２つの台部材３、４は、それぞれ、天板部１１、２１が脚部１２、２２に対して着脱可能であって、かつ表裏反転させることが可能となっている。 In the present embodiment, the top plates 11 and 21 of the two base members 3 and 4 are attachable to and detachable from the legs 12 and 22, respectively, and can be turned upside down.
　つまり、天板部１１、２１と脚部１２、２２とは別個独立して構成されており、天板部１１、２１は脚部１２、２２の上に載っているだけであり、特別な固定は行われていない。 That is, the tops 11 and 21 and the legs 12 and 22 are separately and independently configured, and the tops 11 and 21 only rest on the legs 12 and 22 and special fixing Has not been done.
　そのため、天板部１１、２１を表裏反転させることにより、図３の２点鎖線で示すように、傾斜縁部１１ｄ，２１ｄの傾斜方向を反転させ、天板部１１、２１の形状を長手方向の中心線を中心として左右反転させることができる。 Therefore, as shown by a two-dot chain line in FIG. 3, the inclination directions of the inclined edges 11 d and 21 d are inverted by reversing the top plates 11 and 21 so that the shapes of the top plates 11 and 21 become longitudinal It can be flipped horizontally around the center line of.
　また、天板部１１、２１を脚部１２、２２の上に載せる場合に、幅方向においては天板部１１、２１と脚部１２、２２とを一致させることになるが、長さ方向においては、天板部１１、２１が脚部１２、２２からはみ出さない範囲で適当に自由にずらせることができる。 In addition, when placing the tops 11 and 21 on the legs 12 and 22, in the width direction, the tops 11 and 21 and the legs 12 and 22 coincide with each other, but in the length direction The top plate portions 11 and 21 can be freely displaced as long as the top plate portions 11 and 21 do not protrude from the leg portions 12 and 22.
　なお、天板部１１、２１は脚部１２、２２の上端部に載せるだけであり、特別な固定装置を設けていない。天板部１１、２１は相当の重量を有するので、脚部１２、２２の上に載せるだけでも、その重力によって十分に安定する。しかし、より一層の安定を望む場合には、適当な固定装置を設けてもよい。 The top plates 11 and 21 are simply placed on the upper ends of the legs 12 and 22, and no special fixing device is provided. Since the tops 11 and 21 have a considerable weight, even if they are placed on the legs 12 and 22, they are sufficiently stabilized by their gravity. However, if further stability is desired, suitable fixing devices may be provided.
　そのような固定装置として、例えば、天板部１１、２１の側面に係合部を設け、その係合部に対して着脱可能な係合装置を脚部１２、２２の上部に設ける。または、天板部１１、２１の下面に対して真空吸着するようなパッドを、脚部１２、２２の上部に設ける。 As such a fixing device, for example, engaging portions are provided on the side surfaces of the top plate portions 11 and 21 and engaging devices that can be attached to and detached from the engaging portions are provided on the upper portions of the leg portions 12 and 22. Alternatively, a pad that is vacuum-sucked to the lower surface of the top plate portion 11 or 21 is provided on the upper portion of the leg portion 12 or 22.
　また、固定装置ではないが、脚部１２、２２の上端面に摩擦係数の大きな部材を取り付けておき、摩擦によって天板部１１、２１を滑り難くすることでもよい。例えば、スタンド３１ａ～ｄの上端面、または、長側板３２ａ，ｂ、短側板３３ａ，ｂの上端面などに、合成ゴムなどからなる適当なサイズの複数個の摩擦部材を取り付けておけばよい。 Further, although not a fixing device, a member having a large coefficient of friction may be attached to the upper end surfaces of the legs 12 and 22 so that the top plates 11 and 21 become less slippery by friction. For example, on the upper end surfaces of the stands 31a to 31d or the upper end surfaces of the long side plates 32a and 32b and the short side plates 33a and 33b, a plurality of friction members made of synthetic rubber may be attached.
　なお、脚部１２、２２は、保管または運搬のために、折り畳み可能な構造、またはネジなどで容易に組み立て分解が可能な構造としておいてよい。 The legs 12 and 22 may have a foldable structure or a structure that can be easily assembled and disassembled with a screw or the like for storage or transportation.
　図７において、ネット部材５は、基板４１、基板４１の両端部に設けられたポール４２ａ，４２ｂ、および、ポール４２ａ，４２ｂ間に張られたネット４３を有し、これらが一体になったものである。 In FIG. 7, the net member 5 has a substrate 41, poles 42a and 42b provided at both ends of the substrate 41, and a net 43 stretched between the poles 42a and 42b, and these are integrated It is.
　基板４１は、幅が、自立可能な程度の寸法、例えば数十ｍｍないし百ｍｍ程度、具体的には５０ｍｍ程度である。また、長さが、天板部１１、２１の幅Ｗ２よりも大きく、例えば幅Ｗ２の１．５倍～２倍程度である。例えば、天板部１１、２１の幅Ｗ２が３０ｍｍの場合に、基板４１の長さは６０ｍｍ程度とすればよい。 The substrate 41 has a width that allows self-supporting, for example, about several tens of mm to about 100 mm, specifically about 50 mm. In addition, the length is larger than the width W2 of the top portions 11, 21 and is, for example, about 1.5 to 2 times the width W2. For example, when the width W2 of the top plates 11 and 21 is 30 mm, the length of the substrate 41 may be about 60 mm.
　ポール４２ａ，４２ｂは、ネット４３を張るためのものであり、基板４１の両端部において垂直に取り付けられる。 The poles 42 a and 42 b are for stretching the net 43 and are vertically attached at both ends of the substrate 41.
　基板４１およびポール４２ａ，４２ｂの材料として、木材、合板、プラスチック、金属などを用いることができる。 Wood, plywood, plastic, metal or the like can be used as the material of the substrate 41 and the poles 42a and 42b.
　ネット４３は、国際規格の卓球台に用いられるものと同じ材質および形状であってよく、長さが国際規格のものよりも短い。ネット４３は、基板４１の底面からネット４３の上部までの長さ（高さ）が、国際規格におけるネットの高さＨ２と同じとなるよう、ポール４２ａ，４２ｂ間に張られた状態で固定されている。 The net 43 may be the same material and shape as those used for the international standard table tennis table, and the length is shorter than that of the international standard. The net 43 is fixed in a stretched state between the poles 42a and 42b so that the length (height) from the bottom of the substrate 41 to the top of the net 43 is the same as the height H2 of the net in the international standard. ing.
　ネット部材５は、一列になるように配置した２つの天板部１１、２１の境界部分の上面に載置して使用される。 The net member 5 is used by being placed on the upper surface of the boundary portion between the two top plates 11 and 21 arranged in a line.
　本実施形態の卓球台１は、図１または図６に実線で示すように長手方向に一列になるような配置（ストレート配置）としたときに、ストレートのサーブまたはラリーの練習を行うことができる。 The table tennis table 1 of the present embodiment can practice straight serve or rally when arranged in a line in the longitudinal direction (straight arrangement) as shown by a solid line in FIG. 1 or 6. .
　また、本実施形態の卓球台１は、図６に２点鎖線で示すように、２つの天板部１１、２１を、それぞれの端縁部１１ｃ，２１ｃを間隔をあけた状態で対向させて長手方向に一列になるように配置したときに、その全体の長さを国際規格の卓球台の対角線の長さに一致させることが可能となっている。 Further, as shown by a two-dot chain line in FIG. 6, the table tennis table 1 of the present embodiment makes the two top plates 11 and 21 face each other with their respective edge portions 11 c and 21 c spaced apart. When arranged in a line in the longitudinal direction, it is possible to match the overall length to the diagonal length of the international standard table tennis table.
　つまり、天板部１１、２１を図６に示すように対角線に沿って配置したときに、傾斜縁部１１ｄ，２１ｄが国際規格の卓球台の短辺の一部と一致するように、角度α１が設定されている。 That is, when the tops 11 and 21 are arranged along a diagonal as shown in FIG. 6, the angle α1 is set so that the inclined edges 11d and 21d coincide with part of the short sides of the international standard table tennis table. Is set.
　図６に２点鎖線で示す配置（フォアクロス配置）とした場合の卓球台１Ｂが、図８に示されている。 The table tennis table 1B in the case of the arrangement (forecross arrangement) indicated by a two-dot chain line in FIG. 6 is shown in FIG.
　図８において、卓球台１Ｂは、台部材３、４、およびネット部材５Ｂを有する。 In FIG. 8, the table tennis table 1B has base members 3, 4 and a net member 5B.
　台部材３、４は、図１～図５で説明したものと同じであるが、ネット部材５Ｂは、上で説明したネット部材５に薄板部４４が追加されている。 The base members 3 and 4 are the same as those described with reference to FIGS. 1 to 5, but the net member 5B has a thin plate portion 44 added to the net member 5 described above.
　すなわち、図８のように卓球台１Ｂをフォアクロス配置とした場合に、２つの天板部１１、２１の境界部分の間隔Ｄ１が大きくなるので、その間隔Ｄ１を埋めてネット部材５の載置を可能とするために、薄板部４４が用いられる。薄板部４４の長さは、フォアクロス配置とした場合の天板部１１、２１の境界部分の間隔Ｄ１よりも大きくしておけばよい。薄板部４４の幅については、特に制限はないが、天板部１１、２１の幅Ｗ２と同じとするか、またはそれよりも小さい寸法としてもよい。薄板部４４の厚さは、薄い程使用に際して好ましいが、適当な剛性を有する程度の厚さとしておけばよい。例えば、薄板部４４の材料を、木材、合板、プラスチックなどとした場合は、厚さを１ｍｍ～数ｍｍ程度とすればよく、材料を金属とした場合は、厚さを数分の１ｍｍ～１ｍｍ程度とすればよい。 That is, when the table tennis table 1B is arranged in the forecross arrangement as shown in FIG. 8, since the distance D1 between the boundary portions of the two top plates 11 and 21 becomes large, the distance D1 is filled to place the net member 5 A thin plate 44 is used to make it possible. The length of the thin plate portion 44 may be made larger than the distance D1 of the boundary portion between the top plate portions 11 and 21 in the forecross arrangement. The width of the thin plate portion 44 is not particularly limited, but may be the same as or smaller than the width W 2 of the top plate portions 11 and 21. The thickness of the thin plate portion 44 is preferably as thin as possible in use, but may be set to a thickness having an appropriate rigidity. For example, when the material of the thin plate portion 44 is wood, plywood, plastic or the like, the thickness may be about 1 mm to several mm, and when the material is metal, the thickness may be a few mm to 1 mm It should be a degree.
　ネット部材５Ｂは、天板部１１、２１の中央部において、傾斜縁部１１ｄ，２１ｄに対して平行となるように配置される。 The net member 5B is disposed in parallel to the inclined edge portions 11d and 21d at the central portion of the top plate portions 11 and 21.
　なお、ネット部材５の基板４１の幅を間隔Ｄ１よりも大きくして天板部１１、２１の上に直接に載置可能とした場合には、薄板部４４は不要である。 When the width of the substrate 41 of the net member 5 is made larger than the interval D1 so as to be able to be placed directly on the top plates 11 and 21, the thin plate portion 44 is unnecessary.
　卓球台１を図８に示すようにフォアクロス配置とすることにより、フォアによるクロスのサーブまたはラリーの練習が行える。 By placing the table tennis table 1 in the forecross arrangement as shown in FIG. 8, it is possible to practice serving or rallying crosses by the fore.
　なお、ストレート配置の卓球台１をフォアクロス配置の卓球台１Ｂに変更するには、台部材３、４を、それぞれ床平面上で反転させてフォアクロス配置となるように移動させればよい。その後に、ネット部材５Ｂを配置すればよい。 In order to change the table tennis table 1 in the straight arrangement to the table tennis table 1B in the forecross arrangement, the base members 3 and 4 may be moved on the floor plane so as to be in the forecross arrangement. Thereafter, the net member 5B may be disposed.
　または、台部材３、４を床平面上で少し回転させてフォアクロス配置に対応する位置とした後、それぞれの天板部１１、２１のみを反転させることによって、フォアクロス配置としてもよい。この場合に、脚部１２、２２を互いに少し離すようにすればなお良い。 Alternatively, after the base members 3 and 4 are slightly rotated on the floor plane to be at a position corresponding to the forecross arrangement, the forecross arrangement may be performed by inverting only the top plate portions 11 and 21. In this case, it is better if the legs 12 and 22 are slightly separated from each other.
　または、台部材３、４をその位置のままで、フォアクロス配置に変更することも可能である。つまり、卓球台１の台部材３、４を長手方向にのみ移動させて少し離した後、天板部１１、２１のみを反転させることにより、フォアクロス配置の卓球台１Ｂとすることもできる。 Alternatively, it is also possible to change the arrangement of the base members 3 and 4 to the forecross position as it is. That is, by moving only the table members 3 and 4 of the table tennis table 1 only in the longitudinal direction and separating them slightly, it is possible to make the table tennis table 1B of the forecross arrangement by reversing only the top plates 11 and 21.
　さらに、卓球台１Ｂの天板部１１、２１を表裏反転させることにより、角度α１の正負が反転して傾斜縁部１１ｄ，２１ｄの傾斜方向が反転するので、２つの天板部１１、２１を、図６に示す対角線とは異なる他方の対角線に沿って配置することが可能である。 Furthermore, by reversing the top and bottom portions 11, 21 of the table tennis table 1B, the positive and negative of the angle α1 are reversed and the inclination directions of the inclined edges 11d and 21d are inverted. It is possible to arrange along another diagonal different from the diagonal shown in FIG.
　すなわち、卓球台１Ｂの天板部１１、２１を表裏反転させることにより、図９に示すバッククロス配置の卓球台１Ｃとすることができる。 That is, by inverting the table tops 11 and 21 of the table tennis table 1B, the table tennis table 1C of the back cross arrangement shown in FIG. 9 can be obtained.
　図９において、卓球台１Ｃは、卓球台１Ｂと同じ構成要素である、台部材３、４、およびネット部材５Ｂを有する。 In FIG. 9, the table tennis table 1C has base members 3 and 4 and a net member 5B which are the same components as the table tennis table 1B.
　卓球台１Ｃと卓球台１Ｂとの相違は、天板部１１、２１が表裏反転していることと、表裏反転した天板部１１、２１の傾斜縁部１１ｄ，２１ｄに対応して、ネット部材５Ｂがそれと平行に配置されることである。 The difference between the table tennis table 1C and the table tennis table 1B is that the tabletops 11 and 21 are upside down, and the net members are corresponding to the inclined edges 11d and 21d of the tabletops 11 and 21 reversed. 5B is to be placed parallel to it.
　すなわち、図８に示す卓球台１Ｂの天板部１１、２１を表裏反転させることにより、容易に図９に示すバッククロス配置の卓球台１Ｃとすることができる。 That is, by inverting the top and bottom portions 11, 21 of the table tennis table 1B shown in FIG. 8, the table tennis table 1C of the back cross arrangement shown in FIG. 9 can be easily obtained.
　卓球台１Ｃをバッククロス配置とすることにより、バックによるクロスのサーブまたはラリーの練習が行える。 By placing the table tennis table 1C in the back cross arrangement, it is possible to practice the cross serve or rally by the back.
　このように、天板部１１、２１を表裏反転させ、傾斜縁部１１ｄ，２１ｄに対して平行となるようにネット部材５Ｂを配置することにより、卓球台１Ｂと卓球台１Ｃとの間で容易に変更することができる。 Thus, by arranging the net members 5B so that the tops 11 and 21 are turned upside down and parallel to the inclined edges 11d and 21d, it is easy between the table tennis table 1B and the table tennis table 1C. Can be changed to
　このように、本実施形態の卓球台１は、台部材３、４または天板部１１、２１の配置または表裏を変更することにより、ストレート、フォアクロス、またはバッククロスのいずれの練習をも行うことができる。 Thus, the table tennis table 1 of the present embodiment performs either straight, forecross, or backcross practice by changing the arrangement or front and back of the base members 3 and 4 or the top plate portions 11 and 21. be able to.
　しかも、ストレート、フォアクロス、またはバッククロスのいずれの練習においても、それぞれの卓球台１，１Ｂ，１Ｃは、国際規格に合ったサイズであるため、国際規格サイズの卓球台と同等の本格的な練習を行うことができる。 Moreover, in any practice of straight, forecross, or backcross, the respective table tennis tables 1, 1B and 1C are the size according to the international standard, so they are as serious as the international standard size table tennis table You can practice.
　また、本実施形態の卓球台１は、国際規格の卓球台の一部分から構成されるものであるから、仮想的な国際規格の卓球台の全体の配置にとらわれることなく、卓球台１，１Ｂ，１Ｃを設置する部屋のスペースに応じて都合のよい配置とすることがでる。したがって、従来のような広い場所でなくても、例えば家庭におけるリビングルームやガレージなどにおいても、卓球台１，１Ｂ，１Ｃを用いて国際規格サイズの卓球台と同等の本格的な練習を行うことができる。 Moreover, since the table tennis table 1 of this embodiment is comprised from a part of table tennis table of international standard, table tennis table 1, 1 B, without being caught in the whole arrangement | positioning of the table tennis table of virtual international standard. The arrangement can be made convenient according to the space of the room where 1 C is installed. Therefore, even if it is not a large place as before, for example, in a living room or a garage at home, using a ping-pong table 1, 1B, 1C to perform a full-scale practice equivalent to a ping-pong table of international standard size Can.
　なお、ネット部材５の基板４１の部分、およびネット部材５Ｂの基板４１および薄板部４４の部分については、天板部１１、２１よりも出っ張っているため、国際規格の卓球台とは若干異なった状態となっている。しかし、それらはネットに近い部分であるため、通常のサーブやラリーの練習にはほとんど差し支えない。 The base 41 of the net member 5 and the base 41 of the net member 5B and the thin plate portion 44 of the net member 5B project beyond the top plate portions 11 and 21 and are therefore slightly different from the table tennis table of the international standard. It is in the state. However, because they are close to the net, they are almost safe for regular serve and rally practice.
　上に述べた実施形態の卓球台１において、ネット部材５を天板部１１、２１の中央に配置するのは極めて容易である。 In the table tennis table 1 of the embodiment described above, it is extremely easy to arrange the net member 5 at the center of the top plate portions 11 and 21.
　上に述べた実施形態の卓球台１Ｂ，１Ｃにおいて、ネット部材５Ｂを天板部１１、２１の中央に配置するのを容易とするために、配置位置の目印を薄板部４４に設けておいてもよい。例えば、ネット部材５Ｂを卓球台１Ｂ，１Ｃのそれぞれに合わせた配置とするために、薄板部４４に基板４１の外形に沿った線を描いておくことでもよい。 In the table tennis table 1B, 1C of the embodiment described above, in order to make it easy to arrange the net member 5B at the center of the top plate 11, 21, a mark of the arrangement position is provided on the thin plate 44 It is also good. For example, in order to arrange the net member 5B in accordance with the table tennis tables 1B and 1C, a line along the outer shape of the substrate 41 may be drawn on the thin plate portion 44.
　また、ネット部材５，５Ｂを天板部１１、２１または薄板部４４に固定するための固定装置を設けておいてもよい。 In addition, a fixing device for fixing the net members 5 and 5B to the top plate portions 11 and 21 or the thin plate portion 44 may be provided.
　また、卓球台１Ｂ，Ｃにおいて、天板部１１、２１の端縁部１１ｃ，２１ｃの間隔Ｄ１の目印を薄板部４４に設けておいてもよい。また、端縁部１１ｃ，２１ｃの間隔Ｄ１を規定するための適当な位置決め部材を薄板部４４に設けておいてもよい。 Further, in the table tennis table 1B, 1C, a mark of the distance D1 between the edge portions 11c, 21c of the top plates 11, 21 may be provided on the thin plate portion 44. Further, an appropriate positioning member may be provided on the thin plate portion 44 for defining the distance D1 between the end edge portions 11c and 21c.
　例えば図１０（Ａ）に示すような薄板部４４Ｂを用いる。薄板部４４Ｂは、薄板４４１、および、薄板４４１の下面に取り付けられた突起４４２ａ，ｂからなる。突起４４２ａ，ｂの外側面間が、間隔Ｄ１と一致した寸法となっている。 For example, a thin plate portion 44B as shown in FIG. 10 (A) is used. The thin plate portion 44 B includes a thin plate 441 and protrusions 442 a and 44 b attached to the lower surface of the thin plate 441. The dimension between the outer surfaces of the protrusions 442a and 442b is the same as the distance D1.
　天板部１１、２１の端縁部１１ｃ，２１ｃを突起４４２ａ，ｂの外側面に当接させることにより、天板部１１、２１は適切な位置に位置決めされ、容易にクロス配置の卓球台１Ｂ，Ｃとすることができる。 By bringing the end edges 11c and 21c of the tops 11 and 21 into contact with the outer surfaces of the protrusions 442a and b, the tops 11 and 21 can be positioned at appropriate positions, and the table tennis table 1B of the cross arrangement can be easily crossed. , C.
　または、図１０（Ｂ）（Ｃ）に示すような薄板部４４Ｃを用いる。薄板部４４Ｃを製造するには、金属板例えば薄い鉄板を準備し、その両側を直角程度に折り曲げて耳部４４３ａ，ｂを形成する。耳部４４３ａ，ｂは、それぞれの長さを間隔Ｄ１と同じ寸法としておき、相互の間隔を天板部１１、２１の幅Ｗ２よりも小さい寸法としておく。 Alternatively, a thin plate portion 44C as shown in FIG. 10 (B) (C) is used. In order to manufacture the thin plate portion 44C, a metal plate, for example, a thin iron plate is prepared, and both sides thereof are bent at a right angle to form the ear portions 443a, b. The ear portions 443a, b have the same length as the distance D1, and the distance between the ear portions 443a, b is smaller than the width W2 of the top plate portions 11, 21.
　天板部１１、２１の端縁部１１ｃ，２１ｃを耳部４４３ａ，ｂの端部に当接させることにより、天板部１１、２１は適切な位置に位置決めされ、容易にクロス配置の卓球台１Ｂ，Ｃとすることができる。 By bringing the edge portions 11c and 21c of the top plate portions 11 and 21 into contact with the end portions of the ear portions 443a and b, the top plate portions 11 and 21 are positioned at appropriate positions, and the table tennis table of cross arrangement is easily It can be 1B and C.
　上に述べた実施形態の卓球台１は、２つの台部材３、４を幅方向に並べ、天板部１１、２１の長辺縁部同士が互いに接する状態て配置することが可能である。 The table tennis table 1 of the embodiment described above can arrange two base members 3 and 4 in the width direction, and can be disposed in a state where the long side edge portions of the top plates 11 and 21 are in contact with each other.
　すなわち、図１１に示す卓球台１Ｄにおいて、２つの台部材３、４が、天板部１１、２１の短い方の長辺縁部１１ｂ，２１ｂが互いに接する状態で並行して配置されている。 That is, in the table tennis table 1D shown in FIG. 11, the two base members 3 and 4 are arranged in parallel with the shorter long side edge portions 11b and 21b of the top plates 11 and 21 in contact with each other.
　また、天板部１１、２１の傾斜縁部１１ｄ，２１ｄを相手コートに近い側に配置し、かつ傾斜縁部１１ｄ，２１ｄの先端の長い方が幅方向の外側に位置するように配置することにより、傾斜縁部１１ｄ，２１ｄの出っ張った部分を利用してネット部材５を端縁部１１ｃ，２１ｃからの距離がＬ２の位置に安定して配置することができる。 In addition, the inclined edges 11d and 21d of the top plate portions 11 and 21 are disposed on the side closer to the opposing coat, and the longer ends of the inclined edges 11d and 21d are disposed on the outer side in the width direction. Thus, the net member 5 can be stably disposed at a position where the distance from the end edge portions 11c and 21c is L2 by utilizing the protruding portions of the inclined edge portions 11d and 21d.
　したがって、卓球台１Ｄの幅Ｗ３は、天板部１１、２１の幅Ｗ２の２倍となる。幅Ｗ２が国際規格の幅Ｗ１の４分の１である場合には、幅Ｗ３は、国際規格の幅Ｗ１の丁度２分の１となる。また、卓球台１Ｄの長さＬ２は、国際規格の長さＬ１の半分となりる。つまり、卓球台１Ｄは、国際規格の卓球台のダブルスにおけるサービス時の自コートと同じ領域広さとなる。 Therefore, the width W3 of the table tennis table 1D is twice the width W2 of the tops 11 and 21. When the width W2 is a quarter of the width W1 of the international standard, the width W3 is exactly half the width W1 of the international standard. The length L2 of the table tennis table 1D is half of the length L1 of the international standard. That is, the table tennis table 1D has the same area as the court at the time of service in the doubles of the international standard table tennis table.
　したがって、卓球台１Ｄを用いて、ダブルスにおけるサーブまたはレシーブについて、国際規格サイズの卓球台と同等の本格的な練習を行うことができる。 Therefore, using the ping pong table 1D, it is possible to perform a full-scale practice equivalent to the international standard size table tennis table for serving or receiving in doubles.
　また、前方に適当な高さの衝立６を設置することにより、打った卓球ボールを衝立６により跳ね返るようにして一人でラリーの練習を行うことも可能である。 In addition, it is possible to practice the rally alone by making the hit table tennis ball bounce back by the screen 6 by setting the screen 6 of a suitable height ahead.
　なお、上に述べた実施形態において、天板部１１、２１の長い方の長辺縁部１１ａ，２１ａの長さＬ２ａ、短い方の長辺縁部１１ｂ，２１ｂの長さＬ２ｂ、角度α１、クロス配置とした場合の端縁部１１ｃ，２１ｃの間隔Ｄ１などは、作図によってまたは計算によって容易に求めることができる。
〔第二の実施形態の卓球台〕
　次に、他の形状の天板部１１Ｅ、２１Ｅを用いた第二の実施形態の卓球台１Ｅについて説明する。 In the embodiment described above, the length L2a of the long side edges 11a and 21a of the long side of the top 11 and 21, the length L2b of the long side edges 11b and 21b of the short side, the angle α1, The distance D1 between the edge portions 11c and 21c in the case of the cross arrangement can be easily obtained by drawing or calculation.
[Ping Pong Table of Second Embodiment]
Next, the table tennis table 1E of 2nd embodiment using top- plate parts 11E and 21E of another shape is demonstrated.
　図１２において、卓球台１Ｅは、互いに同じ形状の２つの台部材３Ｅ、４Ｅ、およびネット部材５を有する。 In FIG. 12, the table tennis table 1E has two base members 3E, 4E and a net member 5 which have the same shape.
　台部材３Ｅ、４Ｅは、第一の実施形態の卓球台１の天板部１１、２１とは形状の異なる天板部１１Ｅ、２１Ｅを有する。しかし、第一の実施形態の卓球台１の脚部１２、２２と同じ脚部１２、２２を有するので、脚部１２、２２についてはここでの図示および説明は省略する。 The base members 3E and 4E have top plate portions 11E and 21E different in shape from the top plate portions 11 and 21 of the table tennis table 1 of the first embodiment. However, since it has the same legs 12 and 22 as the legs 12 and 22 of the table tennis table 1 of the first embodiment, the illustration and the description here of the legs 12 and 22 will be omitted.
　また、ネット部材５についても、第一の実施形態のネット部材５と同じであるので、ここでの説明は省略する。 Moreover, since it is the same as that of the net member 5 of 1st embodiment also about the net member 5, description here is abbreviate | omitted.
　図１３において、天板部１１Ｅ、２１Ｅには、長手方向における一方の端部に当該天板部１１Ｅ、２１Ｅの幅方向に沿った端縁部１１ｃ，２１ｃが、長手方向における他方の端部に当該天板部１１Ｅ、２１Ｅの幅方向に対して角度α２（度）だけ傾斜した傾斜縁部１１ｄ，２１ｄが、それぞれ形成されている。ここでの角度α２は、図３に示す天板部１１、２１の角度α１よりも若干大きくなる。 In FIG. 13, in the top portions 11E and 21E, the edge portions 11c and 21c along the width direction of the top portions 11E and 21E at one end in the longitudinal direction are the other end in the longitudinal direction. Inclined edge portions 11d and 21d are formed at an angle α2 (degrees) with respect to the width direction of the top plate portions 11E and 21E. The angle α2 here is slightly larger than the angle α1 of the top plate portions 11 and 21 shown in FIG.
　また、天板部１１Ｅ、２１Ｅには、それぞれの傾斜縁部１１ｄ，２１ｄにおいて、当該傾斜縁部１１ｄ，２１ｄに対して直角である直角傾斜縁部１１ｅ，２１ｅが設けられている。傾斜縁部１１ｄ，２１ｄと直角傾斜縁部１１ｅ，２１ｅとによって、コーナー部ＣＢが形成されている。 The top plate portions 11E and 21E are provided with right-angled inclined edges 11e and 21e which are perpendicular to the inclined edges 11d and 21d at the respective inclined edges 11d and 21d. A corner portion CB is formed by the inclined edges 11d and 21d and the right-angled inclined edges 11e and 21e.
　天板部１１Ｅ、２１Ｅにおける直角傾斜縁部１１ｅ，２１ｅの長さは、傾斜縁部１１ｄ，２１ｄの長さよりも短くした方が、通常のクロス練習には都合がよい。しかし、これらの長さは、種々変更して設定することができる。例えば、これらの長さを互いに同じとしてもよい。または、天板部１１Ｅ、２１Ｅの長い方の長辺縁部１１ａ，２１ａと短い方の長辺縁部１１ｂ，２１ｂとの長さが互いに同じとなるように、傾斜縁部１１ｄ，２１ｄおよび直角傾斜縁部１１ｅ，２１ｅの長さを設定してもよい。 It is convenient for normal cross practice to make the lengths of the right angle inclined edges 11e and 21e in the top plate parts 11E and 21E shorter than the lengths of the inclined edges 11d and 21d. However, these lengths can be variously changed and set. For example, these lengths may be equal to one another. Alternatively, the inclined edges 11d and 21d and the right angle may be set so that the lengths of the long side edges 11a and 21a of the long sides of the top portions 11E and 21E and the long side edges 11b and 21b of the short sides become the same. The lengths of the inclined edges 11 e and 21 e may be set.
　図１２に示されるように、２つの天板部１１Ｅ、２１Ｅは、その傾斜縁部１１ｄ，２１ｄを互いに突き合わせた状態で長手方向に一列に配置され、図１に示す卓球台１と同様に全体の長さＬ１が国際規格の長さＬ１に一致するようになっている。 As shown in FIG. 12, the two top plate portions 11E and 21E are arranged in a line in the longitudinal direction with their inclined edges 11d and 21d butted together, and are generally the same as the table tennis table 1 shown in FIG. The length L1 of the frame is made to match the length L1 of the international standard.
　この場合に、２つの天板部１１Ｅ、２１Ｅの間には、直角傾斜縁部１１ｅ，２１ｅを有するために切り欠かれた部分が生じているが、その部分にはネット部材５が載っているので、その切り欠かれた部分はほとんど目立たない。 In this case, a cutaway portion is generated between the two top plate portions 11E and 21E because of the right angled edges 11e and 21e, but the net member 5 is mounted on that portion So that cutaway part is hardly noticeable.
　本実施形態の卓球台１Ｅによって、第一の実施形態の卓球台１と同様に、ストレートのサーブまたはラリーの練習を行うことができる。 Similar to the table tennis table 1 of the first embodiment, the table tennis table 1E of this embodiment can practice straight serve or rally.
　図１２および図１３に示す台部材３Ｅ、４Ｅを用いてフォアクロス配置の卓球台１Ｆとした例が図１４に示されている。 The example made into the table tennis table 1F of a forecross arrangement | positioning using the base members 3E and 4E shown to FIG. 12 and FIG. 13 is shown by FIG.
　すなわち、図１４において、卓球台１Ｆは、台部材３Ｅ、４Ｅ、およびネット部材５Ｅを有する。 That is, in FIG. 14, the table tennis table 1F includes base members 3E and 4E and a net member 5E.
　台部材３Ｅ、４Ｅは、図１２および図１３で説明したものと同じである。ネット部材５Ｅは、ネット部材５に薄板部４４Ｅが追加されている。この実施形態での薄板部４４Ｅは、図８および図９で示した卓球台１Ｂ，１Ｃの薄板部４４よりも長さが若干長い。しかし、その長さの差は僅かであるので、薄板部４４Ｅとして、卓球台１Ｂ，１Ｃの薄板部４４と同じものを用いることが可能である。 The base members 3E and 4E are the same as those described in FIGS. 12 and 13. In the net member 5E, a thin plate portion 44E is added to the net member 5. The thin plate portion 44E in this embodiment is slightly longer in length than the thin plate portions 44 of the table tennis tables 1B and 1C shown in FIGS. However, since the difference in length is small, it is possible to use the same thin plate portion 44E as the thin plate portion 44 of the table tennis table 1B, 1C.
　また、薄板部４４Ｅとして、図１０（Ａ）～（Ｃ）に示すような薄板部４４Ｂ、４４Ｃを用いることも可能である。その場合に、突起４４２ａ，ｂの外側面間または耳部４４３ａ，ｂの長さを、図６に示す間隔よりも若干大きい間隔Ｄ２としておけばよい。 Further, thin plate portions 44B and 44C as shown in FIGS. 10A to 10C can be used as the thin plate portion 44E. In that case, the distance between the outer surfaces of the protrusions 442a and 44b or the length of the ear portions 443a and b may be set to a distance D2 slightly larger than the distance shown in FIG.
　なお、これら角度α２および間隔Ｄ２などについても、作図または計算によって容易に求めることができる。 The angle α2 and the interval D2 can be easily obtained by drawing or calculation.
　図１４に示すフォアクロス配置の卓球台１Ｆによって、フォアによるクロスのサーブまたはラリーの練習が行える。この場合に、図８の卓球台１Ｂと比べてコーナー部ＣＢが完全な形で実現されているので、コーナー部ＣＢを利用したサーブなどの練習をより一層正確に行うことができる。 The table tennis table 1F of the fore cross arrangement shown in FIG. 14 can practice for serving or rallying crosses by the fore. In this case, since the corner portion CB is realized in a complete form as compared with the table tennis table 1B of FIG. 8, the practice such as serving using the corner portion CB can be performed more accurately.
　また、図示は省略したが、卓球台１Ｅを図９に示すようなバッククロス配置とすることも容易に可能である。
〔第三の実施形態の卓球台〕
　次に、他の形状の天板部１１Ｇ、２１Ｇを用いた第三の実施形態の卓球台１Ｇについて説明する。 Moreover, although illustration is abbreviate | omitted, it is also easily possible to set it as the back cross arrangement | positioning as shown in FIG. 9 in the table tennis table 1E.

　台部材ＧＥ、４Ｇは、第一の実施形態の卓球台１の天板部１１、２１とは形状の異なる天板部１１Ｇ、２１Ｇを有する。しかし、第一の実施形態の卓球台１の脚部１２、２２と同じ脚部１２、２２を有するので、脚部１２、２２についてはここでの図示および説明は省略する。 The base members GE, 4G have top plate portions 11G, 21G different in shape from the top plate portions 11, 21 of the table tennis table 1 of the first embodiment. However, since it has the same legs 12 and 22 as the legs 12 and 22 of the table tennis table 1 of the first embodiment, the illustration and the description here of the legs 12 and 22 will be omitted.
　ネット部材５Ｇについては、第一の実施形態のネット部材５に対して長さが短くなっているが、その他の構造および形状などは同じであるので、ここでの説明は省略する。 The length of the net member 5G is shorter than that of the net member 5 of the first embodiment, but the other structure, shape, and the like are the same, so the description thereof is omitted here.
　図１６において、天板部１１Ｇ、２１Ｇは、それぞれ、長手方向に沿って延びる互いに平行な長辺縁部１１ａ，１１ｂ、２１ａ，２１ｂを有し、幅方向に沿って延びる互いに平行な端縁部１１ｃ，１１ｆ、２１ｃ，２１ｆを有する。

　また、脚部１２、２２にフックを直接に取り付けるのではなく、短側板３３ａ，ｂの間に丸棒状の、ポールを掛け渡しておき、そのポールに、例えばＳ字フックやハンガーなどをつり下げるようにしてよい。また、長側板３２ａ，ｂの間に多数のポールを掛け渡しておいてもよい。 Also, instead of attaching the hooks directly to the legs 12 and 22, a round bar-like pole is bridged between the short side plates 33a and 33b, and an S-shaped hook or a hanger is suspended on the pole, for example. You may do so. Also, a large number of poles may be bridged between the long side plates 32a and 32b.
　また、そのようなポール自体を短側板３３ａ，ｂに対して着脱可能としておいてもよい。 In addition, such a pole itself may be detachable from the short side plates 33a and 33b.
　例えば、図２３に示すように、短側板３３ａ，ｂに穴３４ａ，ｂを設けておき、短側板３３ａ，ｂの間隔よりも若干長いポールＰＬの両端をその穴３４ａ，ｂに挿入して掛け渡す。ポールＰＬにＳ字フックＦＫを掛け、種々の物品ＢＰをつり下げる。 For example, as shown in FIG. 23, holes 34a and 34b are provided in the short side plates 33a and 33b, and both ends of the pole PL slightly longer than the distance between the short side plates 33a and 33b are inserted into the holes 34a and 34b hand over. The S-shaped hook FK is hung on the pole PL, and the various articles BP are suspended.
　このようにすれば、ポールＰＬをそのまま穴３４ａ，ｂから引き抜いて取り外すことにより、容易のそれらの物品ＢＰをポールＰＬごと移動することができる。 In this way, it is possible to easily move those articles BP together with the pole PL by pulling out and removing the pole PL from the holes 34a and 34b as it is.
　また、穴３４ａ，ｂに代えて、短側板３３ａ，ｂの上部に開口する凹部を設けておき、天板部１１、２１を外すことによってポールＰＬを脚部１２、２２の上部から着脱可能としておいてもよい。短側板３３ａ，ｂをスタンド３１ａ～ｄの上端面から少し下げて天板部１１、２１との間に間隙ができようにしておき、その間隙にポールＰＬが入り込むようにしてもよい。 Further, in place of the holes 34a and 34b, a concave portion opened at the upper portion of the short side plates 33a and 33b is provided, and the pole PL can be detachably attached to the upper portion of the leg portions 12 and 22 You may leave it. The short side plates 33a and 33b may be slightly lowered from the upper end surfaces of the stands 31a to 31d so that a gap is formed between the short side plates 33a and b and the top plates 11 and 21, and the pole PL may be inserted into the gap.
　なお、卓球台１を練習のために使用する場合においても、ポールＰＬおよび物品ＢＰを脚部１２、２２の取り付けたままにしておいても差し支えない。 Even when the table tennis table 1 is used for practice, the pole PL and the article BP may be left attached to the legs 12 and 22.
　図２３において、天板部１１、２１の上には花瓶ＫＢが載っているが、卓球の練習に使用するときは他の場所へ移動させればよい。 In FIG. 23, the vase KB is placed on the top plate parts 11 and 21, but when used for table tennis practice, it may be moved to another place.
　台部材３、４を並列に配置することにより、クローゼットとしても使用可能である。 By arranging the base members 3 and 4 in parallel, it can also be used as a closet.
　また、脚部１２、２２の構造または形状を種々変更することによって、陳列棚、整理棚、または収納棚などとして用いることができる。
〔卓球台のゲーム用品としての利用〕
　上に述べた実施形態の卓球台１，１Ｂ～１Ｇを、その構造を変更しまたは適当なアイテムを追加することにより、ゲーム用品として利用することができる。 Moreover, by changing the structure or shape of the legs 12 and 22 variously, it can be used as a display rack, a storage rack, a storage rack, or the like.
[Use as table tennis equipment as game supplies]
The table tennis tables 1 and 1B-1G of the embodiment described above can be used as game supplies by changing the structure or adding appropriate items.
　図２４には、卓球台１を用いた卓球ゲームの構成の例が示されている。 FIG. 24 shows an example of the configuration of a table tennis game using the table tennis table 1.
　図２４において、卓球台１の相手側コートである天板部２１の端部領域に、位置検出センサ６１が載置されている。位置検出センサ６１は、その表面の領域が複数の検出領域ＫＲ１～４に分割されており、それぞれの検出領域ＫＲ１～４に卓球ボールが当たったときにその旨を示す検出信号Ｓ１を出力する。 In FIG. 24, a position detection sensor 61 is placed on an end area of the top board 21 which is the opponent side court of the table tennis table 1. The position detection sensor 61 has a surface area divided into a plurality of detection areas KR1 to K4, and outputs a detection signal S1 indicating that when the table tennis ball hits each of the detection areas KR1 to K4.
　図２４に示す例では、検出領域ＫＲ１はコーナー領域、検出領域ＫＲ２は端縁領域、検出領域ＫＲ３は側縁領域、検出領域ＫＲ４は中央領域である。 In the example shown in FIG. 24, the detection area KR1 is a corner area, the detection area KR2 is an edge area, the detection area KR3 is a side edge area, and the detection area KR4 is a central area.
　位置検出センサ６１からの検出信号Ｓ１は、タブレット（端末装置）６２に入力され、端末装置６２において検出信号Ｓ１に対して種々の演算および統計などが行われ、その結果が表示面ＧＭに表示される。 The detection signal S1 from the position detection sensor 61 is input to the tablet (terminal device) 62, and various calculations and statistics are performed on the detection signal S1 in the terminal device 62, and the result is displayed on the display surface GM. Ru.
　すなわち、タブレット６２において、検出信号Ｓ１に基づいて、各検出領域ＫＲ１～４に卓球ボールが当たった回数が検出され、それに基づいて点数などが表示される。 That is, in the tablet 62, the number of times the table tennis ball hits each of the detection areas KR1 to K4 is detected based on the detection signal S1, and a score or the like is displayed based thereon.
　例えば、卓球ボールが位置検出センサ６１に当たる毎に、検出領域ＫＲ１では１０点、検出領域ＫＲ２では５点、検出領域ＫＲ３では４点、検出領域ＫＲ４では１点を加算する。例えば、複数人が、交互に、天板部１１の側からラケットで卓球ボールを打ち、そのときの点数またはそれまでの合計点を競い合う。または、１人当たり所定回数、例えば２０回を打って、各自が合計点数を競う。また、所定時間内での合計点数を競う。 For example, every time a table tennis ball hits the position detection sensor 61, 10 points in the detection area KR1, 5 points in the detection area KR2, 4 points in the detection area KR3, and 1 point in the detection area KR4 are added. For example, a plurality of people alternately hit table tennis balls with a racket from the side of the top plate portion 11, and compete for the points at that time or the total points so far. Alternatively, each person competes in the total score, hitting a predetermined number of times, for example, 20 times. In addition, the player competes for a total score within a predetermined time.
　また、このような位置検出センサ６１およびタブレット６２は、個人の卓球の練習における成果の指標として用いることができる。すなわち、目標の領域（位置）にどれだけ正確に打ち込めるかを示す指標として使用できる。その場合に、表示面ＧＭに合計点数を表示してもよく、検出領域ＫＲ１～４のいずれに当たったかをその都度表示するようにしてもよい。その際に、検出領域ＫＲ１～４に対する点数の設定を種々変更できるようにすればよい。 Moreover, such a position detection sensor 61 and the tablet 62 can be used as a parameter | index of the result in the exercise of an individual's table tennis. That is, it can be used as an index indicating how accurately the target area (position) can be struck. In that case, the total score may be displayed on the display surface GM, and which of the detection regions KR1 to KR4 is hit may be displayed each time. At this time, the setting of the score for the detection areas KR1 to K4 may be changed variously.
　また、位置検出センサ６１の検出領域の形状は種々変更してもよい。検出領域ＫＲ１～４において、当たったことを検出するだけでなく、当たったときの衝撃の強さ、卓球ボールの回転による摩擦の大きさなどを検出するようにしてもよい。これらの検出結果を表示面ＧＭに表示し、またデータベース化することにより、練習の成果を確認することができる。 Further, the shape of the detection area of the position detection sensor 61 may be variously changed. In the detection areas KR1 to KR4, not only detection of hitting, but also strength of impact upon hitting, magnitude of friction due to rotation of a table tennis ball, etc. may be detected. The results of the practice can be confirmed by displaying these detection results on the display surface GM and creating a database.
　また、天板部１１、２１の上面を、種々のゲームのために使用することができる。例えば、天板部１１、２１の上面に将棋の盤面を載せて、または将棋の盤面を描いた天板部１１、２１を載せることにより、将棋を楽しむこともできる。 In addition, the upper surfaces of the top plates 11 and 21 can be used for various games. For example, it is possible to enjoy shogi by placing the board surface of the shogi on the top surface of the top board parts 11 and 21 or placing the top board parts 11 and 21 on which the board surface of the shogi is drawn.
　また、傾斜を設けた天板部１１、２１の上面に、将棋の駒などを将棋倒しまたはドミノ倒しのために並べておき、将棋倒しまたはドミノ倒しを楽しむこともできる。天板部１１、２１に傾斜をつけるためには、例えば、天板部１１、２１と脚部１２、２２との間の一部に嵩上げ部材を挿入するか、またはスタンド３１ａ～ｄの下端部の一部に嵩上げ部材を挿入するか、またはスタンド３１ａ～ｄの下端部に高さ調整のための部材を設けておくなど、種々の方法を採用し得る。 In addition, on top of the sloped top plate portions 11 and 21, it is possible to arrange a chess piece, etc., for shogi-don or domino defeat, and enjoy shogi-don or domino defeat. In order to incline the top plate portions 11 and 21, for example, a raising member is inserted into a part between the top plate portions 11 and 21 and the leg portions 12 or 22 or the lower end portions of the stands 31a to 31d Various methods may be employed, such as inserting the raising member into a part of the part or providing a member for height adjustment at the lower end of the stands 31a to 31d.
　また、卓球台１を用いて雪合戦ゲームを楽しむことも可能である。雪合戦ゲームでは、卓球ボールを雪玉として用い、台部材３、４をシェルターとして用いればよい。白色の卓球ボールを使用するチームと橙色の卓球ボールを使用するチームとに分かれてゲームを行ってもよい。 Moreover, it is also possible to enjoy a snowball fight game using the ping-pong table 1. In the snowball fight game, a table tennis ball may be used as a snowball, and base members 3 and 4 may be used as a shelter. The game may be divided into a team using white table tennis balls and a team using orange table tennis balls.
　雪合戦ゲームでは、雪玉を相手に当てるだけでなく、適当な容器またはネットを準備しておき、雪玉をそれら容器またはネットに入れた個数で勝敗を競うようにしてもよい。 In the snowball fight game, not only the snowballs but also suitable containers or nets may be prepared, and the snowballs may be put in the containers or nets to compete for the outcome.
　その他、卓球台１，１Ｂ～１Ｇを種々の用途に用いることが可能である。 In addition, it is possible to use table tennis table 1, 1B-1G for various uses.
