Description

【０００１】
【発明の属する技術分野】
本発明は、内側と外側の二重構造の載せ台に人が載ることにより体重や体脂肪率や重心動揺等の生体情報を計測する生体計測重量装置の外側載せ台に関する。
【０００２】
【従来の技術】
従来、生体計測重量装置の中の一種に、載せ台に人が載ることにより体重や体脂肪率を計測する体脂肪計付き体重計がある。図４は従来の体脂肪計付き体重計の載せ台であり、図４（ａ）は側面図、図４（ｂ）は裏面図を示す。また、図５は図４の断面Ｂ−Ｂ矢視図である。これら図４、図５に示すように、体脂肪計付き体重計の載せ台は、内側載せ台２１と外側載せ台２２の二重構造である。内側載せ台２１は、圧延鋼板をプレス成形することにより作られ、積載板２３の裏側の周囲に側板２４を形成し、被計測者が載っても永久変形することない強度を有している。また、外側載せ台２２は、内側載せ台２１と重なる母体となる母体部２７と、生体インピーダンスを計測するための電極３９と、計測を開始するためのスイッチ部３１からなっている。
【０００３】
そして、母体部２７は、樹脂を射出成形することにより作られ、積載板２５の裏側の周囲に側板２６を形成し、外観を美しくみせるための外装の役目をしている。また、積載板２５の裏側には内側載せ台２１と重なったときに、内側載せ台２１との間で水平方向にずれを起こさないようにリブ３０を形設している。更に、このリブ３０の先端部分の要所に内側載せ台２１が垂直方向に抜け落ちないように係止する係止部３３を形設している。電極３９は積載板２５の表側に、スイッチ部３１は母体部２７の側板２６から裏側にかけて配設している。また、スイッチ部３１は、スイッチ蓋３４、基板３５、スイッチ本体３６、二重コイルバネ３７、釦３８等により構成している。
【０００４】
【発明が解決しようとする課題】
しかし、上述の外側載せ台２２の母体部２７に形設するリブ３０の係止部３３は、成形時において、母体部２７を金型から取り出す際に、金型の開閉方向（図４の矢印Ｄ方向）に対して引っかかりとなる部分、すなわち、アンダーカットである。したがって、母体部２７を成形する際の金型は、金型の開閉方向と直交する方向（図４の矢印Ｃ方向）にスライドコアを移動させるような複雑な構造にしなければならなかった。したがって、母体部２７を成形する際の金型が高価なものであった。
【０００５】
そこで、本発明は、上記のような従来の問題点を解決することを目的とするもので、外側載せ台の製作にかかる金型コストを軽減することができる生体計測重量装置の外側載せ台を提供することを課題とする。
【０００６】
【課題を解決するための手段】
内側載せ台と重なり合ったときに抜け落ちないように係止する係止部を有する生体計測重量装置の外側載せ台において、前記係止部の少なくとも一箇所以上を前記外側載せ台の母体となる母体部に配設する部品に備える。外側載せ台の母体部に配設する部品に係止部を備えることで、母体部に形設する係止部の箇所が減り、その箇所分の金型のスライドコアを移動させる構造をなくすことができる。一方、外側載せ台の母体部に配設する部品は、係止部を備えても係止部を備える前と同様な金型で製作できる。したがって、総合的に外側載せ台を製作するための金型コストを廉価なものとすることができる。
【０００７】
更に、前記外側載せ台の母体部に配設する部品は、計測開始するためのスイッチ部の外枠であるスイッチ蓋とする。もともと外側載せ台の母体部の裏側かけて形成されているスイッチ部の外枠であるスイッチ蓋に係止部を備えることは、もっとも効率的に母体部のリブに形設する係止部の代用を図ることができる。
【０００８】
【発明の実施の形態】
以下、実施の形態を図面に基づき説明する。まず、第一の実施の形態について詳述する。図１は生体計測重量装置の載せ台であり、図１（ａ）は側面図、図１（ｂ）は裏面図を示す。また、図２は図１の断面Ａ−Ａ矢視図である。本発明の生体計測重量装置の外側載せ台２は、内側載せ台１と重なる母体となる母体部２８と、生体インピーダンスを計測するための電極１７と、計測を開始するためのスイッチ部１１からなる。
【０００９】
母体部２８は、人が載る部分である積載板５と、この積載板５の裏側の周囲に形成する側板６と、内側載せ台１と重なり合ったときに水平方向にずれを起こさないように積載板５の裏側に形設するリブ７、８、９、１０と、スイッチ部１１の近くに位置するリブ７の先端部分でスイッチ部１１から離れた箇所に内側載せ台１と重なり合ったときに垂直方向に抜け落ちないように係止する係止部１５と、スイッチ部１１と離れたところに位置するリブ９の先端部分の要所に内側載せ台１と重なり合ったときに垂直方向に抜け落ちないように係止する係止部１３を形設する。
【００１０】
電極１７は積載板５の表側に配設している。
【００１１】
スイッチ部１１は母体部２８の側板６から裏側にかけて配設している。そして、その構造は、公知の技術からなり、例えば特開平１０−３２６５３４号公報に開示されているような形態であるので詳細な説明は省略するが、このスイッチ部１１の外枠をなすスイッチ蓋１４については外側載せ台２の母体部２８の裏側にかかるように形成する。そして、母体部２８の裏側にかかるスイッチ蓋１４の先端部分には、内側載せ台１と重なり合ったときに垂直方向に抜け落ちないように係止する係止部１２を形設する。
【００１２】
内側載せ台１と外側載せ台２とを重ね合わせるには、スイッチ部１１を配設した状態の外側載せ台２の係止部１２、１３、１５の部分を外側に押し広げながら、外側載せ台２のリブ７、８、９、１０に囲まれた内側に内側載せ台１を入れ込む。外側載せ台２の係止部１２、１３、１５部分を外側に押し広げることにより、外側載せ台２の積載板５や側板６やリブ７、８、９、１０の部分がたわみ、外側載せ台２の係止部１２、１５と係止部１３との間隔が内側載せ台１の外形幅よりも広がり、内側載せ台１を入れ込むことができる。
【００１３】
内側載せ台１の積載板３の裏側の周囲に形成する側板４のうち、相対する側板の端面の一方をリブ９の係止部１３で係止し、他方をリブ７の係止部１５とスイッチ蓋１４の係止部１２で係止するので外側載せ台２と内側載せ台１とは抜け落ちないものとなる。
【００１４】
外側載せ台２の母体部２８のリブ７に形設する一部の係止部をスイッチ蓋１４に形設することで、母体部２８を成形するための金型のスライドコアを移動させる構造部分の軽減が図ることができる。
【００１５】
なお、内側載せ台１と外側載せ台２とを重ね合わせるには、スイッチ部１１を配設しない状態、すなわち、スイッチ部１１の外枠をなすスイッチ蓋１４を取り付ける前の外側載せ台２の母体部２８に、母体部２８の係止部１３、１５の部分を外側に押し広げながら、母体部２８のリブ７、８、９、１０に囲まれた内側に内側載せ台１を入れ込み、後からスイッチ部１１の外枠をなすスイッチ蓋１４を取り付けてもよい。
【００１６】
次に、第二の実施の形態について詳述する。図３は、別形態の生体計測重量装置の載せ台であり、図３（ａ）は側面図、図３（ｂ）は裏面図を示す。本発明の生態計測重量装置の外側載せ台４７は、内側載せ台４６と重なる母体となる母体部２９と、生体インピーダンスを計測するための電極１８と、計測を開始するためのスイッチ部５１からなる。
【００１７】
第一の実施の形態の説明でした生体計測重量装置の外側載せ台２とほぼ同様の構成であるが、外側載せ台４７の母体部２９に形設するリブ４１、４２、４３、４４のうち、スイッチ部５１と離れたところに位置するリブ４３の先端部分の要所にだけ係止部５５を形設するところと、釦５８を複数有するスイッチ部５１のスイッチ蓋５４の先端部分の要所に複数の係止部５２を形設するところが異なる。
【００１８】
内側載せ台４６と外側載せ台４７とを重ね合わせるには、スイッチ部５１を配設した状態の外側載せ台４７の係止部５２、５５の部分を外側に押し広げながら、外側載せ台４７のリブ４１、４２、４３、４４に囲まれた内側に内側載せ台４６を入れ込めばよい。
【００１９】
内側載せ台４６の側板４９のうち、側板の相対する端面の一方をリブ４３の係止部５５で係止し、他方をスイッチ蓋５４の係止部５２で係止するので外側載せ台４７と内側載せ台４６とは抜け落ちないものとなる。
【００２０】
外側載せ台４７の母体部２９のリブ４１に形設する全ての係止部をスイッチ蓋５４に形設することで、母体部２９を成形するための金型のスライドコアを移動させる構造部分の軽減をより図ることができる。
【００２１】
なお、内側載せ台４６と外側載せ台４７とを重ね合わせるには、スイッチ部５１を配設しない状態、すなわち、スイッチ部５１の外枠をなすスイッチ蓋５４を取り付ける前の外側載せ台４７の母体部２９に、母体部２９の係止部５５の部分を外側に押し広げながら、母体部２９のリブ４１、４２、４３、４４に囲まれた内側に内側載せ台４６を入れ込み、後からスイッチ部５１の外枠をなすスイッチ蓋５４を取り付けてもよい。
【００２２】
本発明は、外側載せ台に配設する部品を他にも設けているような形態の外側載せ台であれば、更にリブに形設する係止部を外側載せ台に配設する部品に形設でき、金型コストの軽減につなげることができる。
【００２３】
【発明の効果】
本発明の生体計測重量装置の外側載せ台は、外側載せ台の母体部のリブに形設する係止部を、外側載せ台の母体部に配設する部品に形設したことにより、母体部を成形するための金型のスライドコアを移動させる構造部分が軽減し、外側載せ台の製作にかかる金型コストが廉価なものとなる。また、もともと外側載せ台の裏側かけて形成されているスイッチ部の外枠であるスイッチ蓋に係止部を備えることで、もっとも効率的に母体部のリブに形設する係止部の代用を図ることができ、外側載せ台の製作にかかる金型コストが廉価なものにできる。

BACKGROUND OF THE INVENTION
The present invention relates to an outer platform of a biometric weight device that measures biological information such as body weight, body fat percentage, and sway of a center of gravity when a person is placed on a platform having a dual structure of inner and outer sides.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a body scale with a body fat scale that measures body weight and body fat percentage by placing a person on a platform as one type of biometric weighing apparatus. FIG. 4 is a table for a conventional weight scale with a body fat scale. FIG. 4 (a) is a side view and FIG. 4 (b) is a back view. 5 is a cross-sectional view taken along arrow BB in FIG. As shown in FIGS. 4 and 5, the platform of the body scale with a body fat scale has a double structure of an inner platform 21 and an outer platform 22. The inner stage 21 is made by press-molding a rolled steel sheet. The inner stage 21 is formed with a side plate 24 around the back side of the stacking plate 23 and has a strength that does not permanently deform even when the measurement subject is placed. The outer platform 22 includes a mother body 27 that is a parent body overlapping the inner platform 21, an electrode 39 for measuring bioimpedance, and a switch unit 31 for starting measurement.
[0003]
The base part 27 is made by injection molding of resin, forms a side plate 26 around the back side of the stacking plate 25, and serves as an exterior for making the appearance beautiful. Further, a rib 30 is formed on the back side of the stacking plate 25 so as not to cause a horizontal displacement with the inner platform 21 when it overlaps the inner platform 21. Further, a locking portion 33 that locks the inner platform 21 so that it does not fall off in the vertical direction is formed at an important point of the tip portion of the rib 30. The electrode 39 is arranged on the front side of the stacking plate 25, and the switch part 31 is arranged from the side plate 26 to the back side of the base part 27. The switch unit 31 includes a switch lid 34, a substrate 35, a switch body 36, a double coil spring 37, a button 38, and the like.
[0004]
[Problems to be solved by the invention]
However, the locking portion 33 of the rib 30 formed on the mother body portion 27 of the outer stage 22 described above is used when the mother body portion 27 is taken out of the mold during molding. It is a portion that becomes caught with respect to (D direction), that is, an undercut. Therefore, the mold for molding the base part 27 has to have a complicated structure in which the slide core is moved in a direction (arrow C direction in FIG. 4) orthogonal to the opening / closing direction of the mold. Therefore, the mold for molding the base part 27 is expensive.
[0005]
Therefore, the present invention aims to solve the conventional problems as described above, and provides an outer platform of a biometric weight device that can reduce the mold cost required for the production of the outer platform. The issue is to provide.
[0006]
[Means for Solving the Problems]
In the outer platform of the biometric weight device having a latching portion that latches so as not to fall off when overlapped with the inner platform, at least one of the latching portions serves as a parent body of the outer platform. It prepares for the parts to be arranged. By providing the locking part to the parts arranged on the base part of the outer platform, the number of locking parts formed on the base part is reduced, and the structure for moving the slide core of the mold corresponding to that part is eliminated. Can do. On the other hand, the parts arranged on the base part of the outer stage can be manufactured with the same mold as before the locking part even if the locking part is provided. Therefore, the mold cost for manufacturing the outer stage in a comprehensive manner can be reduced.
[0007]
Further, the component arranged on the base part of the outer stage is a switch lid which is an outer frame of the switch part for starting measurement. The switch lid, which is the outer frame of the switch part that is originally formed on the back side of the mother part of the outer platform, is provided with a latch part, which is the most efficient substitute for the latch part that is formed on the rib of the mother part. Can be achieved.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments will be described with reference to the drawings. First, the first embodiment will be described in detail. FIG. 1 shows a platform for a biometric weight device, FIG. 1 (a) shows a side view, and FIG. 1 (b) shows a back view. 2 is a cross-sectional view taken along the line AA in FIG. The outer platform 2 of the living body measurement weight device of the present invention includes a mother body 28 that is a mother body that overlaps the inner platform 1, an electrode 17 for measuring bioimpedance, and a switch unit 11 for starting measurement. .
[0009]
The mother body 28 is loaded so as not to cause horizontal displacement when it overlaps with the loading plate 5 on which a person is placed, the side plate 6 formed around the back side of the loading plate 5 and the inner platform 1. When the rib 7, 8, 9, 10 formed on the back side of the plate 5 overlaps the inner platform 1 at a position away from the switch portion 11 at the tip portion of the rib 7 located near the switch portion 11. So that it does not fall off in the vertical direction when it overlaps with the inner platform 1 at a key portion at the tip of the rib 9 located away from the switch portion 11. A locking portion 13 to be locked is formed.
[0010]
The electrode 17 is disposed on the front side of the stacking plate 5.
[0011]
The switch part 11 is arranged from the side plate 6 to the back side of the base part 28. The structure of the switch lid 11 is an outer frame of the switch unit 11, since the structure is a known technique, for example, as disclosed in Japanese Patent Application Laid-Open No. 10-326534. 14 is formed so as to cover the back side of the base body 28 of the outer stage 2. A locking portion 12 is formed at the tip of the switch lid 14 on the back side of the base portion 28 so as not to fall off in the vertical direction when it overlaps the inner platform 1.
[0012]
In order to superimpose the inner stage 1 and the outer stage 2, the outer stage 2 is extended while the locking portions 12, 13, 15 of the outer stage 2 with the switch portion 11 disposed thereon are pushed outward. The inner platform 1 is inserted into the inside surrounded by the two ribs 7, 8, 9, 10. By pushing the engaging portions 12, 13, 15 of the outer platform 2 outward, the loading plate 5, the side plate 6, and the ribs 7, 8, 9, 10 of the outer platform 2 are deflected, and the outer platform 2 The distance between the two locking portions 12 and 15 and the locking portion 13 is wider than the outer width of the inner platform 1 so that the inner platform 1 can be inserted.
[0013]
Of the side plates 4 formed around the back side of the loading plate 3 of the inner platform 1, one of the end surfaces of the opposite side plates is locked by the locking portion 13 of the rib 9, and the other is locked with the locking portion 15 of the rib 7. Since it is latched by the latching portion 12 of the switch lid 14, the outer platform 2 and the inner platform 1 do not fall off.
[0014]
A structural portion for moving a slide core of a mold for forming the base portion 28 by forming a part of the locking portion formed on the rib 7 of the base portion 28 of the outer platform 2 on the switch lid 14. Can be reduced.
[0015]
In order to superimpose the inner stage 1 and the outer stage 2, the base of the outer stage 2 before the switch lid 14 that forms the outer frame of the switch unit 11 is attached, that is, the switch unit 11 is not provided. The inner platform 1 is inserted into the inner portion surrounded by the ribs 7, 8, 9, 10 of the mother body 28 while pushing the locking portions 13, 15 of the mother body 28 outward. A switch lid 14 that forms an outer frame of the switch unit 11 may be attached.
[0016]
Next, the second embodiment will be described in detail. 3A and 3B show a platform for another form of the biometric weight device, where FIG. 3A shows a side view and FIG. 3B shows a back view. The outer platform 47 of the ecological measurement weight device of the present invention includes a mother body 29 that is a parent body overlapping the inner platform 46, an electrode 18 for measuring bioimpedance, and a switch 51 for starting measurement. .
[0017]
The rib 41, 42, 43, 44 formed on the base body 29 of the outer platform 47 has substantially the same configuration as the outer platform 2 of the biometric weight device described in the first embodiment. The engaging portion 55 is formed only at the main portion of the tip portion of the rib 43 located away from the switch portion 51, and the main portion of the tip portion of the switch lid 54 of the switch portion 51 having a plurality of buttons 58. The difference is that a plurality of locking portions 52 are formed.
[0018]
In order to superimpose the inner stage 46 and the outer stage 47, the engaging parts 52 and 55 of the outer stage 47 in a state where the switch part 51 is disposed are pushed outward and the outer stage 47 is moved. What is necessary is just to insert the inner stage 46 in the inner side surrounded by the ribs 41, 42, 43, and 44.
[0019]
Of the side plates 49 of the inner platform 46, one of the opposite end surfaces of the side plates is locked by the locking portion 55 of the rib 43, and the other is locked by the locking portion 52 of the switch lid 54. The inner stage 46 does not come off.
[0020]
By forming all the locking parts formed on the ribs 41 of the base part 29 of the outer stage 47 on the switch lid 54, the structure part for moving the slide core of the mold for forming the base part 29 is provided. Reduction can be achieved more.
[0021]
In order to superimpose the inner platform 46 and the outer platform 47, the base of the outer platform 47 in a state where the switch unit 51 is not provided, that is, before the switch lid 54 forming the outer frame of the switch unit 51 is attached. The inner support 46 is inserted into the inside of the base 29 surrounded by the ribs 41, 42, 43, 44 while the portion of the locking part 55 of the base 29 is expanded outwardly. A switch lid 54 forming an outer frame 51 may be attached.
[0022]
In the present invention, if the outer stage is in a form in which other parts are provided on the outer stage, a locking portion formed on the rib is further formed on the part provided on the outer stage. This can be used to reduce mold costs.
[0023]
【The invention's effect】
