SOLUTION: The table 50 is supported into a horizontal attitude flush with a top plate 14 by allowing a support member 70 to take an inclined support attitude of gradually ascending toward its tip and by applying an abutment part 71 positioned at the tip to a receiving part 65 on the back face. A stopper 75 which is positioned at a part toward a turning end of the back face of the table 50 and is provided with a locking part 76 for locking an abutment part 71 of the support member 70 in the support attitude, at an inward end and an operation part 77 at an outer end, respectively, is supported turnably around the shaft 82 of a hinge 80 between a locking position (a solid line) where the locking part 76 is locked to the abutment part 71 and a release position (a dotted line) where the locking part 76 releases the locking of the abutment part 71. The stopper 75 is constantly turnably energized to the locking position by the resilient force of a torsion coil spring 84. This constitution prevents a user from forgetting to lock the stopper 75 and surely prevents the table 50 from being unexpectedly folded. COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、配膳車に関する。 The present invention relates to a layout vehicle.

近年、給食等を配膳する手段として、小型の配膳車が老人ホーム等を中心に供されるようになった。これは、一人前の給食を載せたトレイを多数同時に搬送する大型の配膳車とは違い、例えば１０食分程度の温食、冷食をそれぞれホテルパン等の大皿に載せて本体内に収容し、保温、保冷した状態で食堂等の食事をする場所に搬送し、本体の上面に大皿を取り出したのち、個別に食器に盛り付けるようになっている。ここで、上記した大皿を載せるスペースや、盛り付けの作業スペースを拡げるために、跳ね上げ式のサイドテーブルを備えたものも提案されている（例えば、非特許文献１参照。）。
具体的には、本体の側面の上端位置にテーブルが回動可能に設けられるとともに、その下方位置に支え部材が回動可能に設けられており、テーブルを水平姿勢に引き上げることに続いて、支え部材を先上がりの斜め姿勢に引き上げ、支え部材の先端をテーブルの裏面に設けられた受け部に当てることにより、テーブルが本体の上面と面一の水平姿勢で支持されるようになっている。 In recent years, as a means of serving meals, etc., small-sized barges have been provided mainly at nursing homes. This is different from a large trolley that transports many trays loaded with full-time meals at the same time. For example, about 10 servings of hot and cold foods are placed on a plate such as a hotel pan and stored in the main body. Then, it is transported to a place such as a canteen where it is kept cold, and a large plate is taken out from the upper surface of the main body, and then individually placed on the tableware. Here, in order to expand the space for placing the above-mentioned platter and the work space for serving, there has also been proposed one provided with a flip-up side table (for example, see Non-Patent Document 1).
Specifically, a table is rotatably provided at the upper end position of the side surface of the main body, and a support member is rotatably provided at a lower position thereof. The table is supported in a horizontal posture that is flush with the upper surface of the main body by pulling the member up in an oblique posture and applying the tip of the support member to a receiving portion provided on the back surface of the table.

一方テーブルを畳む場合は、テーブルを水平姿勢から所定角度引き上げると、支え部材の先端が受け部から外れることで、支え部材ともどもテーブルが垂下姿勢に畳まれるようになっているが、畳むことを意図しない場合でも、例えばテーブルに人等がぶつかって引き上げられると、不用意にテーブルが畳まれてしまうことがあり得る。
そこでこの従来例では、支え部材の先端に係止するストッパをスライド可能に備え、テーブルが水平姿勢で支持されたところでストッパを前進させて支え部材の先端に係止させることで、不用意にテーブルが持ち上げられた場合でも、テーブルが畳まれることが無いようにしている。
発明協会公開技報番号２００４−５０５４１５号 On the other hand, when folding the table, when the table is lifted from the horizontal posture by a predetermined angle, the tip of the support member is detached from the receiving part, so that the table can be folded into the hanging posture together with the support member. Even if it is not intended, for example, if a person hits the table and pulls it up, the table may be inadvertently folded.
Therefore, in this conventional example, a stopper that is locked to the tip of the support member is slidably provided, and when the table is supported in a horizontal posture, the stopper is advanced and locked to the tip of the support member, thereby inadvertently holding the table. The table will not be folded even if it is lifted.
Japan Society of Invention and Innovation Technical Report No. 2004-505415

しかしながら上記従来例では、ストッパを前進位置にスライドさせない限りは係止機能を果たさないため、前進操作をし忘れたり、前進量が不十分であったりすると、同様にテーブルが不用意に畳まれてしまうおそれがあり、さらなる改良が切望されていた。
本発明は上記のような事情に基づいて完成されたものであって、その目的は、テーブルが不用意に畳まれるのをより確実に防止するところにある。 However, in the above conventional example, unless the stopper is slid to the advance position, the locking function is not performed. Therefore, if the user forgets to perform the advance operation or the advance amount is insufficient, the table is similarly folded carelessly. There was a risk of further improvement, and further improvements were eagerly desired.
The present invention has been completed based on the above circumstances, and an object thereof is to more reliably prevent the table from being accidentally folded.

上記の目的を達成するための手段として、請求項１の発明は、トレイ等を収容する貯蔵室を内部に設けて走行可能とされた本体の側面には、その上端位置にテーブルが回動可能に設けられるとともに、その下方位置に支え部材が回動可能に設けられ、この支え部材が先上がりに傾斜した支持姿勢を取ってその先端の当接部が前記テーブルの裏面に設けられた受け部に当てられることにより、前記テーブルが前記本体の上面と面一の水平姿勢に支持されるようにした配膳車において、前記テーブルの裏面における回動端寄りの位置には、支持姿勢を取った前記支え部材の当接部に対して下方への移動を規制するように係止可能な係止部を内方の端部に、操作部を外方の端部にそれぞれ設けたストッパが、前記係止部が前記支え部材の当接部に係止する係止位置と、前記係止部が前記当接部への係止を解除する解除位置との間で回動軸を中心として回動可能に支持されているとともに、前記ストッパを常には前記係止位置に回動付勢する付勢手段が設けられている構成としたところに特徴を有する。 As a means for achieving the above object, the invention of claim 1 is characterized in that a table can be rotated to the upper end position on the side surface of a main body which is provided with a storage chamber for accommodating a tray or the like and is allowed to run. The support member is rotatably provided at a lower position of the support member. The support member has a support posture in which the support member is inclined upward, and a contact portion at the tip thereof is provided on the back surface of the table. In the arrangement vehicle in which the table is supported in a horizontal posture flush with the upper surface of the main body, the support posture is taken at a position near the rotation end on the back surface of the table. A stopper provided with a locking portion that can be locked to the abutting portion of the support member at the inner end portion and an operation portion at the outer end portion so as to restrict downward movement is provided on the engagement portion. The stop part is engaged with the contact part of the support member. And the stopper is always supported around the rotation axis, and the stopper is always attached to the stopper. It is characterized in that a biasing means for biasing rotation is provided at the locking position.

請求項２の発明は、請求項１に記載のものにおいて、前記ストッパの係止部は、このストッパの内方の端部をストッパの回動軸側に向けて斜めに折り返すことで形成されており、この係止部における傾斜面の外側に対して前記支え部材の当接部の押圧力が作用した場合には、前記ストッパを前記付勢手段の付勢力に抗して前記解除位置側に回動させつつ、前記当接部が前記係止部の内側に進入することが許容される一方、前記係止部の傾斜面の内側に対して前記当接部の押圧力が作用した場合には、前記傾斜面で係止されて前記係止部の外側へ抜脱が阻止されるようになっているところに特徴を有する。
請求項３の発明は、請求項１または請求項２に記載のものにおいて、前記ストッパの係止部は、このストッパの内方の端部を略直角に立ち上げたのち、上部側をストッパの回動軸側に向けて斜めに折り曲げることで形成されているところに特徴を有する。 According to a second aspect of the present invention, in the first aspect of the present invention, the stopper locking portion is formed by turning the inner end portion of the stopper obliquely toward the rotation shaft side of the stopper. When the pressing force of the abutting portion of the support member is applied to the outside of the inclined surface of the locking portion, the stopper is moved to the release position side against the urging force of the urging means. When the contact portion is allowed to enter the inside of the locking portion while rotating, while the pressing force of the contact portion acts on the inside of the inclined surface of the locking portion. Is characterized in that it is locked by the inclined surface and is prevented from being pulled out of the locking portion.
According to a third aspect of the present invention, in the first or second aspect of the present invention, the locking portion of the stopper starts up the inner end of the stopper at a substantially right angle, and then the upper side of the stopper is the stopper. It is characterized in that it is formed by bending obliquely toward the rotating shaft side.

＜請求項１の発明＞
テーブルを起こす場合は、テーブルの回動端側を掴むと同時に、操作部を押してストッパを付勢力に抗して解除位置に回動させ、その状態でテーブルを水平姿勢に向けて引き上げる。それに続いて、支え部材を支持姿勢に引き上げて先端の当接部を受け部に当てることで、テーブルは本体の上面と面一の水平姿勢に支持される。そののち、テーブルの回動端を掴んだ手を離すと、ストッパが付勢力で係止位置に回動し、係止部が支え部材の当接部に係止した状態となる。
このように本発明では、ストッパを常には係止位置に回動付勢する構成としたから、いわゆるストッパの掛け忘れが発生せず、不用意にテーブルが畳まれる事態が生じることを確実に防止できる。 <Invention of Claim 1>
When raising the table, at the same time as grasping the rotation end side of the table, the operation unit is pushed to rotate the stopper against the urging force to the release position, and in this state, the table is pulled up toward the horizontal posture. Subsequently, the table is supported in a horizontal posture flush with the upper surface of the main body by pulling the support member up to the support posture and applying the contact portion to the receiving portion. After that, when the hand holding the rotating end of the table is released, the stopper is rotated to the locking position by the urging force, and the locking portion is locked to the contact portion of the support member.
Thus, in the present invention, since the stopper is always configured to be urged to rotate to the locking position, it is ensured that the so-called forgetting to apply the stopper does not occur and the table is accidentally folded. Can be prevented.

＜請求項２の発明＞
テーブルを起こす操作を行う際に、ストッパの操作部を押圧しなかったり、支え部材の当接部を受け部に当てる前に操作部の押圧を止めた場合は、ストッパが係止位置にあるために、支え部材の当接部を受け部に当てようとした場合に、当接部が係止部で邪魔されてその傾斜面の外側に留まり、テーブルは正規の水平姿勢から持ち上げられた状態に留め置かれる。この場合は、テーブルを水平姿勢に向けて押し下げると、支え部材の当接部は、ストッパを付勢力に抗して解除位置に回動させつつ傾斜面の外面に沿って滑って係止部の内側に入り込み、テーブルが水平姿勢まで押されたところで当接部が受け部に当たってテーブルが支持されるとともに、ストッパが係止位置に戻って係止する。すなわち、テーブルを正規姿勢に自動修正することができる。 <Invention of Claim 2>
When the operation of raising the table is not performed, if the operation part of the stopper is not pressed, or if the operation part is stopped before being applied to the receiving part of the support member, the stopper is in the locking position. In addition, when the contact portion of the support member is to be applied to the receiving portion, the contact portion is obstructed by the locking portion and stays outside the inclined surface, and the table is lifted from the normal horizontal posture. To be retained. In this case, when the table is pushed down toward the horizontal position, the abutment portion of the support member slides along the outer surface of the inclined surface while rotating the stopper to the release position against the urging force and When the table enters inside and the table is pushed to the horizontal posture, the contact portion hits the receiving portion to support the table, and the stopper returns to the locking position and locks. That is, the table can be automatically corrected to the normal posture.

＜請求項３の発明＞
ストッパの係止部が単に傾斜姿勢に形成されているものと比べると、受け部と干渉することなく回動させるために、受け部と係止部の付け根との間に設けられる隙間が狭くでき、ひいては回動軸から係止部の付け根までの長さも短くできる。
ストッパの係止部までの長さが短くできたことで、テーブルを持ち上げる量を小さく抑えても、係止部を、支え部材の当接部が自然落下する場合の軌道の外側に外すことが可能となり、結果テーブルと本体との間にできる隙間を小さく抑えることができる。また、受け部と係止部の隙間が狭くできることでから、係止状態でテーブルが無理に持ち上げられたときにも、当接部が隙間を通って受け部の下側に潜り込むことが防がれる。
もちろん、上側の傾斜面を利用して、支え部材の当接部を係止部の内側に自動的に導入する機能を果たすことができる。 <Invention of Claim 3>
Compared with a stopper that is simply formed in an inclined posture, the gap provided between the receiving portion and the base of the locking portion can be narrowed in order to rotate without interfering with the receiving portion. As a result, the length from the rotating shaft to the base of the locking portion can be shortened.
By shortening the length of the stopper to the locking part, it is possible to remove the locking part to the outside of the track when the abutment part of the support member naturally falls even if the amount of lifting the table is kept small. It becomes possible, and the gap formed between the result table and the main body can be kept small. In addition, since the gap between the receiving part and the locking part can be narrowed, it is possible to prevent the contact part from entering the lower side of the receiving part through the gap even when the table is forcibly lifted in the locked state. It is.
Of course, the function of automatically introducing the abutting portion of the support member into the inside of the locking portion can be achieved using the upper inclined surface.

以下、本発明の実施形態を添付図面に基づいて説明する。
＜実施形態１＞
本発明の実施形態１を図１ないし図１３によって説明する。本実施形態では、温冷蔵タイプの配膳車を例示しており、基本的には、１０食分程度の温食、冷食をそれぞれホテルパンＰ等のトレイ（大皿）に入れ分けて庫内に収容し、保温、保冷した状態で食堂等の食事をする場所に搬送し、上面に大皿を取り出したのち、個別に食器に盛り付けるようになっている。
配膳車は大まかには、図１及び図２に示すように、方形の箱状をなす本体１０が、車輪１１を備えた移動台１２上に載置される一方、本体１０の上面に天板１４が張られた構造であって、天板１４の一端側（正面から見た右側）に設けられたハンドル１５を握りつつ、押しまたは引き操作して走行させるようになっている。移動台１２におけるハンドル１５が設けられた側の端縁には、踏圧式のブレーキ１６が装備されている。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. In the present embodiment, a hot and cold storage type allocation car is illustrated. Basically, about 10 servings of hot food and cold food are separately placed in a tray (large plate) such as a hotel pan P and accommodated in the warehouse. It is transported to a place such as a canteen where the food is kept warm and cold, and a large plate is taken out from the upper surface and then individually placed on the tableware.
As shown in FIG. 1 and FIG. 2, the arrangement car roughly has a rectangular box-like main body 10 placed on a movable table 12 provided with wheels 11, while a top plate is placed on the upper surface of the main body 10. 14 is stretched, and it is made to travel by pushing or pulling while holding a handle 15 provided on one end side (right side as viewed from the front) of the top plate 14. A tread pressure brake 16 is mounted on the end edge of the movable table 12 on the side where the handle 15 is provided.

本体１０内には、正面から見た右側の全高にわたって温蔵室２０が形成されているとともに、左側では、上側のほぼ２／３の高さ領域に冷蔵室２１が形成され、その下側が機械室２２とされている。温蔵室２０の前面開口と、冷蔵室２１の前面開口から機械室２２の前面にわたっては、それぞれ樹脂製の透明窓板２５が張られた扉２４が観音開き式に装着されており、取手２６を持つことで温蔵室２０側では約１８０度、冷蔵室２１側では約９０度開放できるようになっている。
本体１０の前面における両扉２４の間にはオペレーションパネル２７が装着され、温蔵室２０や冷蔵室２１の室内温度を設定する操作部や、温度表示部等が設けられている。 In the main body 10, a warming chamber 20 is formed over the entire height on the right side as viewed from the front, and on the left side, a refrigerating chamber 21 is formed at a height region of approximately 2/3 on the upper side. This is a chamber 22. From the front opening of the warm room 20 and the front opening of the cold room 21 to the front of the machine room 22, doors 24 each having a transparent window plate 25 made of resin are mounted in a double-spreading manner. By holding it, it can be opened at about 180 degrees on the warm room 20 side and about 90 degrees on the cold room 21 side.
An operation panel 27 is mounted between the doors 24 on the front surface of the main body 10, and an operation unit for setting the room temperature of the warm room 20 and the cold room 21, a temperature display unit, and the like are provided.

図３に概略を示すように、右側の温蔵室２０は、複数枚の断熱パネル２９を組み付けた前面開口の断熱箱体３０により形成されている一方、冷蔵室２１は、内外の箱内に発泡ウレタンからなる断熱材３２が充填された前面開口の断熱箱体３３により形成されている。
先に冷蔵構造を説明すると、上記した機械室２２内には、圧縮機、凝縮器等からなる冷凍装置３５が設置されている一方、冷蔵室２１の内壁面２１Ａのうちの左右の側面と天井面の裏面にわたって、銅パイプ等からなる蒸発パイプ３６がジグザク状に配管され、この蒸発パイプ３６が冷凍装置３５と冷媒配管によって循環接続されることで冷凍サイクルが構成されている。 As schematically shown in FIG. 3, the right-side warming chamber 20 is formed by a heat-insulating box 30 having a front opening in which a plurality of heat-insulating panels 29 are assembled, while the refrigerating chamber 21 is placed inside and outside the box. It is formed by a heat insulating box 33 having a front opening filled with a heat insulating material 32 made of urethane foam.
First, the refrigeration structure will be described. In the machine room 22, a refrigeration apparatus 35 including a compressor, a condenser, and the like is installed. An evaporation pipe 36 made of a copper pipe or the like is provided in a zigzag shape across the back surface of the surface, and the evaporation pipe 36 is circulated and connected by a refrigeration apparatus 35 and a refrigerant pipe to constitute a refrigeration cycle.

従って、冷凍装置３５が起動されると、蒸発パイプ３６を流通する冷媒を介して冷蔵室２１の左右及び天井の内壁面２１Ａが冷却され、そこで発生する冷気が自然対流によって循環することで冷蔵室２１内が冷却される。この間、冷蔵室２１に装備された温度センサ（図示せず）によって冷蔵室２１の室内温度が検知され、その検知温度がオペレーションパネル２７により設定された設定温度よりも低くなると冷凍装置３５が停止され、設定温度よりも高くなると冷凍装置３５が再起動されることが繰り返され、冷蔵室２１内がほぼ設定温度に冷却されるようになっている。 Therefore, when the refrigeration apparatus 35 is activated, the left and right sides of the refrigerator compartment 21 and the inner wall surface 21A of the ceiling are cooled via the refrigerant flowing through the evaporation pipe 36, and the cold air generated therein is circulated by natural convection, thereby the refrigerator compartment. The inside of 21 is cooled. During this time, the temperature sensor (not shown) provided in the refrigerator compartment 21 detects the indoor temperature of the refrigerator compartment 21, and when the detected temperature becomes lower than the set temperature set by the operation panel 27, the refrigeration apparatus 35 is stopped. When the temperature becomes higher than the set temperature, the refrigerating apparatus 35 is repeatedly restarted, and the inside of the refrigerator compartment 21 is cooled to almost the set temperature.

一方、温蔵室２０では、内壁面２０Ａのうちの機械室２２と隣接する領域にヒータパネル４０が張られている。ヒータパネル４０の裏面には、図４に示すように、コードヒータ４１Ａが例えばジグザグ状に配線されて貼り付けられている。また、ヒータパネル４０の裏面側には、ファン４３が装備された加熱ファン室４２が機械室２２側に張り出すように設けられ、この加熱ファン室４２内には、ヒータパネル４０との間に間隔を開けて仕切板４４が張られ、この仕切板４４の表面側にもコードヒータ４１Ｂが貼り付けられている。
この仕切板４４とヒータパネル４０との間には吹出流路４５が形成され、その下端に続くヒータパネル４０の下端に吹出口４５Ａが形成されている。また、仕切板４４の裏側には、吸込口４６Ａから吸い込んだ空気をファン４３に向ける吸込流路４６が形成されている。なお、温蔵室２０の左右の側面には、それぞれ手前と奥の位置に、後記するようにホテルパンＰ（図１参照）を支持するための棚柱が設けられているが、そのうち冷蔵室２１に隣接した左側面に設けられた両棚柱では、受け金を止めるために列設された係止孔が、空気の吸引孔を兼ねていて、この係止孔から引かれた空気がダクトを通って加熱ファン室４２の吸込口４６Ａに導かれるようになっている。 On the other hand, in the warm room 20, a heater panel 40 is stretched in a region adjacent to the machine room 22 in the inner wall surface 20A. As shown in FIG. 4, the code heater 41 A is wired and attached to the back surface of the heater panel 40 in a zigzag shape, for example. In addition, a heating fan chamber 42 equipped with a fan 43 is provided on the back surface side of the heater panel 40 so as to protrude toward the machine chamber 22, and the heating fan chamber 42 is provided between the heater panel 40 and the heater panel 40. A partition plate 44 is stretched at an interval, and a code heater 41B is also attached to the surface side of the partition plate 44.
An outlet channel 45 is formed between the partition plate 44 and the heater panel 40, and an outlet 45A is formed at the lower end of the heater panel 40 following the lower end thereof. Further, on the back side of the partition plate 44, a suction flow path 46 that directs air sucked from the suction port 46 A toward the fan 43 is formed. In addition, shelf columns for supporting the hotel pan P (see FIG. 1) are provided on the left and right sides of the warm room 20 at the front and back positions, respectively, as will be described later. In both shelf columns provided on the left side adjacent to 21, the locking holes arranged in order to stop the receiving metal also serve as air suction holes, and the air drawn from the locking holes is ducted. It is led to the suction port 46A of the heating fan chamber 42 through.

従って、コードヒータ４１Ａ，４１Ｂに通電され、またファン４３が駆動されると、まずヒータパネル４０が加熱されてその輻射熱で温蔵室２０内が加熱される。それに加え、温蔵室２０内の空気が棚柱の係止孔から吸引されて加熱ファン室４２の吸込口４６Ａに流入し、図４の矢線に示すように、吸込流路４６を通ってファン４３に導かれたのち吹出流路４５に吐出され、そこを流通する間に加熱されて暖気が生成され、その暖気が吹出口４５Ａから温蔵室２０内に吹き出されるといった循環流が生じ、温蔵室２０内が加熱される。この間、図示しない温度センサによって温蔵室２０の室内温度が検知され、その検知温度がオペレーションパネル２７により設定された設定温度よりも高くなるとコードヒータ４１Ａ，４１Ｂへの通電が遮断され、設定温度よりも低くなるとコードヒータ４１Ａ，４１Ｂへ再度通電されることが繰り返され、温蔵室２０内がほぼ設定温度に加熱されるようになっている。 Accordingly, when the cord heaters 41A and 41B are energized and the fan 43 is driven, the heater panel 40 is first heated and the inside of the warming chamber 20 is heated by the radiant heat. In addition, the air in the storage room 20 is sucked from the locking holes of the shelf columns and flows into the suction port 46A of the heating fan chamber 42, and passes through the suction channel 46 as shown by the arrow in FIG. After being guided to the fan 43, it is discharged into the blowout flow path 45 and heated while flowing therethrough to generate warm air, and a circulating flow is generated in which the warm air is blown into the warming chamber 20 from the blower outlet 45A. The inside of the warm room 20 is heated. During this time, the room temperature of the warm room 20 is detected by a temperature sensor (not shown), and when the detected temperature becomes higher than the set temperature set by the operation panel 27, the energization to the code heaters 41A and 41B is cut off. When the temperature is lower, the cord heaters 41A and 41B are repeatedly energized, and the inside of the warm room 20 is heated to almost the set temperature.

なお上記したように、温蔵室２０の左右の側面には手前と奥に棚柱が設けられているため、複数段にわたって左右一対ずつの断面コ字形のレールが前後の棚柱の間に差し渡されて装着され、温食を入れたホテルパンＰが左右のフランジを左右のレールに嵌めつつ、複数段にわたって収容できるようになっている。
冷蔵室２１の左右の側面にも手前と奥に棚柱が設けられていて、複数段（温蔵室２０側よりも少ない）にわたって左右一対ずつの断面コ字形のレールが前後の棚柱の間に差し渡されて装着され、冷食を入れたホテルパンＰが同じく左右のフランジを左右のレールに嵌めつつ、複数段にわたって収容できるようになっている。 As described above, since the shelf columns are provided on the left and right sides of the warming chamber 20 at the front and the back, a pair of left and right U-shaped rails are inserted between the front and rear shelf columns over a plurality of stages. The hotel pan P that has been delivered and mounted and has hot food can be accommodated in a plurality of stages while fitting the left and right flanges to the left and right rails.
Shelf columns are also provided on the front and back sides of the left and right sides of the refrigerator compartment 21, and a pair of left and right U-shaped rails are provided between the front and rear shelf columns over a plurality of stages (less than the warm compartment 20 side). The hotel pan P, which has been inserted and mounted and has been fed with cold food, can be accommodated in a plurality of stages while the left and right flanges are fitted to the left and right rails.

本体１０におけるハンドル１５を設けた側とは反対の左側面１０Ｌには、跳ね上げ式のテーブル５０が装着されている。上記のように本体１０の上面には天板１４が張られているが、この天板１４は、本体１０の平面形状とほぼ整合した平面長方形に形成され、例えば奥行が６６０mm、間口が９００mm程度に設定されている。また、床面から天板１４の上面までの高さが８５０mm程度に設定されている。この天板１４の上面が、ホテルパンＰ等の載置面や盛り付けの作業面とされており、特に天板１４の上面における手前と奥の端縁には、落下防止用の突条１８が形成されている。 A flip-up table 50 is mounted on the left side surface 10L of the main body 10 opposite to the side on which the handle 15 is provided. As described above, the top plate 14 is stretched on the upper surface of the main body 10. The top plate 14 is formed in a planar rectangle that is substantially aligned with the planar shape of the main body 10. For example, the depth is 660 mm and the frontage is about 900 mm. Is set to The height from the floor surface to the upper surface of the top plate 14 is set to about 850 mm. The top surface of the top plate 14 is used as a mounting surface for the hotel pan P or the like, or a work surface for serving, and in particular, at the front and back edges of the top surface of the top plate 14, a drop-preventing ridge 18 is provided. Is formed.

テーブル５０は、図５ないし図８に示すように、ステンレス鋼板等の金属板によって、方形の浅皿を伏せたような形状に形成されており、奥行（図５の横寸法）が天板１４の奥行と同じであり、また間口（図５の縦寸法）が本体１０の高さの約半分に設定されている。
このテーブル５０の一端側が、本体１０の左側面１０Ｌの上端部に回動可能に支持されている。そのため本体１０の左側面１０Ｌにおける手前と奥の位置には、一対の軸受板５２が縦向きの姿勢で突設されている。この軸受板５２の上端は、天板１４の高さ位置まで突出しており、両軸受板５２の上方突出端には、軸受用の上ブッシュ５３が嵌着されている。 As shown in FIGS. 5 to 8, the table 50 is formed by a metal plate such as a stainless steel plate so that a rectangular shallow dish is turned down, and the depth (horizontal dimension in FIG. 5) is the top plate 14. The frontage (vertical dimension in FIG. 5) is set to about half the height of the main body 10.
One end of the table 50 is rotatably supported by the upper end of the left side surface 10L of the main body 10. Therefore, a pair of bearing plates 52 are projected in a vertically oriented posture at the front and back positions on the left side surface 10L of the main body 10. The upper end of the bearing plate 52 protrudes to the height position of the top plate 14, and a bearing upper bush 53 is fitted to the upper protruding ends of both the bearing plates 52.

一方、テーブル５０の裏面の中央部には、詳しくは後記するように、補強板を兼ねて受けユニット６０が取り付けられており、図８に示すように、この受けユニット６０の手前と奥の側板６２における天板１４と隣接する側の端部には、それぞれ軸６３が外向きに突設されている。この両軸６３が、上記した軸受板５２の上ブッシュ５３に嵌合されることで、テーブル５０は、図６に示す垂下姿勢と、図７に示す水平姿勢との間で回動可能とされている。なおテーブル５０は、水平姿勢よりも所定角度上方に回動可能となっている（図９参照）。
テーブル５０が水平姿勢を取った場合には、その上面が上記した天板１４の上面と面一となるように設定され、このテーブル５０の上面が、ホテルパンＰ等の載置面や盛り付けの作業面の補助面として利用されるようになっている。従って、テーブル５０の上面にも、その手前と奥の端縁に、落下防止用の突条５１が形成されている。
また、後記するようにテーブル５０が水平姿勢で保持された場合に、天板１４との間にできる隙間は極力小さいことが望ましく、そのためにテーブル５０における天板１４と隣接する側の端面の裏面側の角部には丸みが付けられ、回動時に天板１４と干渉することが回避されるようになっている。 On the other hand, a receiving unit 60 serving as a reinforcing plate is attached to the center of the back surface of the table 50 as will be described in detail later. As shown in FIG. 8, the front and back side plates of the receiving unit 60 are provided. A shaft 63 projects outwardly from the end of the side 62 adjacent to the top plate 14. The shafts 50 are fitted into the upper bush 53 of the bearing plate 52 described above, so that the table 50 can be rotated between the hanging posture shown in FIG. 6 and the horizontal posture shown in FIG. ing. The table 50 can be rotated a predetermined angle above the horizontal posture (see FIG. 9).
When the table 50 takes a horizontal posture, the upper surface thereof is set to be flush with the upper surface of the top plate 14 described above, and the upper surface of the table 50 is used for placing a table pan P or the like. It is used as an auxiliary surface for the work surface. Therefore, the protrusions 51 for preventing the fall are formed on the upper surface of the table 50 at the front and back edges.
Further, as will be described later, when the table 50 is held in a horizontal position, it is desirable that the gap formed between the table 50 and the top plate 14 is as small as possible. For this reason, the back surface of the end surface of the table 50 adjacent to the top plate 14 is used. The side corners are rounded to avoid interference with the top plate 14 during rotation.

続いて、テーブル５０を水平姿勢に保持する構造を説明する。テーブル５０の裏面には、図８に示すように、補強板を兼ねた金属板製の受けユニット６０が取り付けられており、この受けユニット６０は、テーブル５０の裏面の中央部における広い領域にわたって重ねられる本体板６１を備えている。この受けユニット６０の本体板６１の裏面には、間口方向の中央から少し回動端側に寄った位置において、奥行方向に長いアングル状をなす受け部６５が、本体板６１から切り起こされて形成されている。この受け部６５は詳細には、図７に示すように、テーブル５０が水平姿勢を取った場合に、テーブル５０の裏面から垂下したのち（垂下部６５Ａ）、天板１４側に向けて直角に曲げられて突出した（突出部６５Ｂ）断面形状となる。 Next, a structure for holding the table 50 in a horizontal posture will be described. As shown in FIG. 8, a receiving unit 60 made of a metal plate that also serves as a reinforcing plate is attached to the back surface of the table 50, and this receiving unit 60 is stacked over a wide area at the center of the back surface of the table 50. The main body plate 61 is provided. On the back surface of the main body plate 61 of the receiving unit 60, a receiving portion 65 having a long angle shape in the depth direction is cut and raised from the main body plate 61 at a position slightly closer to the rotation end side from the center in the frontage direction. Is formed. Specifically, as shown in FIG. 7, the receiving portion 65 hangs from the back surface of the table 50 (hanging portion 65 A) when the table 50 is in a horizontal posture, and then is perpendicular to the top plate 14 side. The cross-sectional shape is bent and protruded (protruding portion 65B).

本体１０の左側面１０Ｌには、支え部材７０が回動可能に支持されている。この支え部材７０は、金属棒を曲げ加工して形成されており、図５に示すように、上記した受け部６５にほぼ等しい長さの当接部７１の両端に、一対のアーム部７２が直角よりもやや開いて曲げられた略コ字形に形成されている。また両アーム部７２の基端には、軸部７３が外側に曲げ形成されている。一方、本体１０の左側面１０Ｌに設けられた上記した一対の軸受板５２には、ほぼ中央高さ位置に、軸受用の下ブッシュ５４が嵌着されている。
従って、支え部材７０の両軸部７３が、軸受板５２の下ブッシュ５４に嵌合されることで、支え部材７０は、軸部７３を中心として回動可能に支持されており、常には自重により垂下姿勢を取るようになっている。 A support member 70 is rotatably supported on the left side surface 10L of the main body 10. The support member 70 is formed by bending a metal bar. As shown in FIG. 5, a pair of arm portions 72 are provided at both ends of the contact portion 71 having a length substantially equal to the receiving portion 65 described above. It is formed in a substantially U shape that is bent slightly open from the right angle. A shaft portion 73 is bent outward at the base ends of both arm portions 72. On the other hand, a lower bushing 54 for bearing is fitted to the pair of bearing plates 52 provided on the left side surface 10L of the main body 10 at a substantially central height position.
Therefore, both shaft portions 73 of the support member 70 are fitted to the lower bushing 54 of the bearing plate 52, so that the support member 70 is supported so as to be rotatable about the shaft portion 73, and always has its own weight. By taking a drooping posture.

そして図７に参照して示すように、支え部材７０を先上がりの斜め姿勢に回動して、先端側の当接部７１を受け部６５における垂下部６５Ａの付け根側に当てたところで、テーブル５０が上記した水平姿勢で支持されるようになっている。また、テーブル５０を水平姿勢から所定角度引き上げると、受け部６５の突出部６５Ｂが当接部７１の軌道Ｋ（図１７参照）の外側に退避するため、支え部材７０が元の垂下姿勢に回動（落下）することが許容され、それに続いてテーブル５０が垂下姿勢に回動することが許容されるようになっている。
ここで、テーブル５０が垂下姿勢に勢い良く回動された場合に、本体１０の左側面１０Ｌに当たるおそれがあるが、その時の衝撃力を緩和するために、テーブル５０の回動端に近い位置の裏面にクッション５６が設けられているとともに、テーブル５０を垂下姿勢でがたつき無く保持するために、テーブル５０、詳細には受けユニット６０の本体板６１の回動端寄りの位置に、本体１０の左側面１０Ｌに吸着するマグネットキャッチ５７が設けられている。また、支え部材７０が本体１０の左側面１０Ｌに衝撃的に当たるのを緩和するために、支え部材７０または本体１０の左側面１０Ｌにクッションシール５８を設けてもよい。 Then, as shown in FIG. 7, when the support member 70 is rotated in an upward oblique posture and applied to the base side of the drooping portion 65 A in the receiving portion 65, a table is formed. 50 is supported in the horizontal posture described above. Further, when the table 50 is pulled up from the horizontal posture by a predetermined angle, the protrusion 65B of the receiving portion 65 is retracted to the outside of the track K of the contact portion 71 (see FIG. 17), so that the support member 70 returns to the original hanging posture. It is allowed to move (drop), and subsequently, the table 50 is allowed to rotate to the hanging posture.
Here, when the table 50 is vigorously rotated to the hanging posture, there is a risk of hitting the left side surface 10L of the main body 10. However, in order to reduce the impact force at that time, the table 50 is located at a position close to the rotation end of the table 50. A cushion 56 is provided on the back surface, and in order to hold the table 50 in a suspended position without rattling, the main body 10 is located at a position near the rotating end of the table 50, specifically the main body plate 61 of the receiving unit 60. A magnet catch 57 that is attracted to the left side surface 10L is provided. In addition, a cushion seal 58 may be provided on the support member 70 or the left side surface 10L of the main body 10 in order to reduce the impact of the support member 70 impacting the left side surface 10L of the main body 10.

また、テーブル５０が水平姿勢から意図することなく持ち上げられて、テーブル５０が不用意に落下することを防止するためにストッパ７５が備えられており、受けユニット６０の裏面における回動端寄りで、かつ手前の端部寄りの位置において、奥行方向に沿った軸線回りの回動可能に支持されている。
詳細にはストッパ７５は、小幅の金属板によって形成され、図７に示すように、一端側には、上面側に鋭角の斜め姿勢で折り返された係止部７６が形成されているとともに、他端側に、上面側に直角曲げされた屈曲部７８が形成され、この他端側が操作部７７となっている。なお、ストッパ７５における長さ方向の中央部から少し操作部７７側に寄った位置に、開口７９が形成されている（図９参照）。 Further, a stopper 75 is provided to prevent the table 50 from being unintentionally lifted from the horizontal posture and inadvertently dropping, and at the rotation end on the back surface of the receiving unit 60, And in the position near the front end, it is supported so as to be rotatable around an axis along the depth direction.
Specifically, the stopper 75 is formed by a small metal plate, and as shown in FIG. 7, a locking portion 76 that is folded back at an acute angle on the upper surface is formed on one end side. A bent portion 78 bent at a right angle on the upper surface side is formed on the end side, and the other end side is an operation portion 77. An opening 79 is formed at a position slightly closer to the operation portion 77 side from the central portion in the length direction of the stopper 75 (see FIG. 9).

一方、受けユニット６０の裏面には、上記した受け部６５から所定寸法回動端側に寄った位置において、取付板６７が同じく本体板６１から切り起こして形成されている。この取付板６７は、テーブル５０が水平姿勢を取った場合に、テーブル５０の裏面から垂下したのち、その垂下端が回動端側を向いて先上がりの斜め姿勢に屈曲された形状となっている。
そしてストッパ７５は、係止部７６をテーブル５０の回動基部側（図７の右側）に、操作部７７を回動端側（同図の左側）に向けた姿勢で配され、蝶番８０の一方の開閉板８１Ａが、ストッパ７５の下面における開口７９の右側の口縁にねじで固定されるとともに、他方の開閉板８１Ｂが、開口７９を通して取付板６７の傾斜面に同じくねじで固定されることにより、ストッパ７５は、図７に示すように、蝶番８０の軸８２を中心として回動可能に支持されている。このとき、ストッパ７５の係止部７６は、受け部６５の突出部６５Ｂの外側を回動し得るようになっており、また操作部７７は、テーブル５０の回動端に近い部分に位置している。 On the other hand, on the back surface of the receiving unit 60, a mounting plate 67 is similarly formed by being cut and raised from the main body plate 61 at a position close to the predetermined dimension rotation end side from the receiving portion 65 described above. When the table 50 is in a horizontal posture, the mounting plate 67 hangs down from the back surface of the table 50, and then the bottom end of the mounting plate 67 is bent in an upward oblique posture toward the rotating end. Yes.
The stopper 75 is arranged in such a posture that the locking portion 76 faces the rotation base side (right side in FIG. 7) of the table 50 and the operation portion 77 faces the rotation end side (left side in FIG. 7). One opening / closing plate 81A is fixed to the right edge of the opening 79 on the lower surface of the stopper 75 with a screw, and the other opening / closing plate 81B is similarly fixed to the inclined surface of the mounting plate 67 through the opening 79 with a screw. Accordingly, the stopper 75 is supported so as to be rotatable about the shaft 82 of the hinge 80 as shown in FIG. At this time, the locking portion 76 of the stopper 75 can rotate outside the protruding portion 65 B of the receiving portion 65, and the operation portion 77 is positioned near the rotation end of the table 50. ing.

また、蝶番８０の軸８２にはねじりコイルばね８４が嵌装され、その一端が一方の開閉板８１Ａに、他端が開口７９を通して他方の開閉板８１Ｂに掛止されていて、その弾力によってストッパ７５には、図７の反時計回り方向の回動力が付勢されるようになっている。
上記したストッパ７５の反時計回り方向の回動は、ストッパ７５における係止部７６を設けた側の端部が受け部６５の突出部６５Ｂに当たることで停止され、これがストッパ７５の係止位置であって、このときストッパ７５はテーブル５０とほぼ平行な姿勢を取り、係止部７６が受け部６５の外側をほぼ覆うようになっている。なお、操作部７７側の屈曲部７８は、受けユニット６０の本体板６１との間に、所定の隙間を開けた状態にある。
ストッパ７５は常には上記の係止位置にあるが、テーブル５０の回動端側を掴むことと併せて操作部７７を押し上げると、ストッパ７５は、ねじりコイルばね８４の弾力に抗して、図７の時計回り方向に回動し、同図の鎖線に示すように、屈曲部７８が本体板６１に当たることでそれ以上の回動が規制される。これがストッパ７５の解除位置であって、このとき係止部７６は受け部６５の外側を開放し、かつ支え部材７０の当接部７１の軌道Ｋの外側に外れるようになっている。 Further, a torsion coil spring 84 is fitted to the shaft 82 of the hinge 80, and one end thereof is hooked to the one opening / closing plate 81A and the other end is hooked to the other opening / closing plate 81B through the opening 79. 75 is energized in the counterclockwise direction in FIG.
The rotation of the stopper 75 in the counterclockwise direction is stopped when the end of the stopper 75 on the side where the locking portion 76 is provided hits the protruding portion 65B of the receiving portion 65, and this is the locking position of the stopper 75. At this time, the stopper 75 takes a posture substantially parallel to the table 50, and the locking portion 76 covers the outside of the receiving portion 65. The bent portion 78 on the operation unit 77 side is in a state where a predetermined gap is opened between the bent portion 78 and the main body plate 61 of the receiving unit 60.
The stopper 75 is always in the above-mentioned locking position. However, when the operation unit 77 is pushed up together with grasping the rotating end side of the table 50, the stopper 75 resists the elasticity of the torsion coil spring 84. 7 is rotated in the clockwise direction, and as shown by the chain line in FIG. This is the release position of the stopper 75. At this time, the locking portion 76 opens the outside of the receiving portion 65 and comes out of the track K of the contact portion 71 of the support member 70.

続いて、本実施形態の配膳車の使用例を説明する。調理された温食や冷食は、それぞれホテルパンＰに入れられ、温食を入れたホテルパンＰはレール上を滑らせつつ温蔵室２０に収容され、また冷食を入れたホテルパンＰは、同じくレール上を滑らせつつ冷蔵室２１に収容される。それとともに、冷却運転並びに加熱運転を行うと、温食は温蔵室２０内で保温され、冷食は冷蔵室２１内で保冷されて待機される。
食事の時間となったら、ハンドル１５を持って押しまたは引き操作することで、当該配膳車が食堂等の食事をする場所に移動される。この間テーブル５０は、垂下姿勢を取り、すなわち畳んだ状態とされる。 Then, the usage example of the layout vehicle of this embodiment is demonstrated. The cooked hot and cold foods are put in the hotel pan P, respectively, and the hotel pan P containing the hot food is accommodated in the warm room 20 while sliding on the rail, and the hotel pan P containing the cold food is Similarly, it is accommodated in the refrigerator compartment 21 while sliding on the rail. At the same time, when the cooling operation and the heating operation are performed, the hot food is kept warm in the warm room 20, and the cold food is kept cold in the cold room 21 and waits.
When it is time for a meal, the handle car is moved to a place such as a dining room by pushing or pulling with the handle 15 to perform a meal. During this time, the table 50 takes a drooping posture, that is, a folded state.

配膳車が所定場所に運ばれたら、ブレーキ１６を踏んで固定したのち、テーブル５０を起こす。それには、テーブル５０の回動端側を掴むと同時に、操作部７７を押してストッパ７５を付勢力に抗して解除位置に回動させ、その状態から図９に示すように、テーブル５０を水平姿勢からさらにその上方に向けて引き上げる。それに続いて、支え部材７０を先上がりの斜め姿勢に引き上げ、当接部７１がテーブル５０（受けユニット６０の本体板６１）の裏面に当たった手応えを感じたら、テーブル５０の回動端を握ったままテーブル５０を下方に戻す。
テーブル５０が水平姿勢に戻されると、図１０に示すように、支え部材７０の当接部７１が本体板６１の裏面を滑りつつ、受け部６５における垂下部６５Ａの付け根部分に当てられ、これによりテーブル５０は天板１４の上面と面一の水平姿勢に支持される。そののち、テーブル５０の回動端を掴んだ手を離すと、操作部７７への押圧力も除去されることで、同図の実線に示すように、ストッパ７５が付勢力で係止位置に回動し、係止部７６が支え部材７０の当接部７１の外側に係止した状態となる。 When the distribution vehicle is carried to a predetermined place, the brakes 16 are stepped on and fixed, and then the table 50 is raised. For this purpose, at the same time as grasping the rotation end side of the table 50, the operating portion 77 is pushed to rotate the stopper 75 against the biasing force to the release position, and from this state, as shown in FIG. Pull up further upward from the posture. Subsequently, when the support member 70 is pulled up in a slanting upward posture and the abutting portion 71 feels that the table 50 (the main body plate 61 of the receiving unit 60) hits the back surface, the holding end of the table 50 is grasped. The table 50 is returned to the lower position.
When the table 50 is returned to the horizontal posture, as shown in FIG. 10, the contact portion 71 of the support member 70 is applied to the base portion of the hanging portion 65A in the receiving portion 65 while sliding on the back surface of the main body plate 61. Thus, the table 50 is supported in a horizontal posture flush with the upper surface of the top plate 14. After that, when the hand holding the rotating end of the table 50 is released, the pressing force to the operation unit 77 is also removed, so that the stopper 75 is moved to the locked position by the urging force as shown by the solid line in FIG. The locking portion 76 is locked to the outside of the contact portion 71 of the support member 70 by rotating.

なお、テーブル５０を起こす操作を行う際に、ストッパ７５の操作部７７を押圧しなかったり、支え部材７０の当接部７１を受け部６５に当てる前に操作部７７の押圧を止めた場合は、ストッパ７５が係止位置にあるために、図１１に示すように、支え部材７０の当接部７１を受け部６５に当てようとした場合に、当接部７１が係止部７６で邪魔されてその傾斜面７６Ａの外側に留まり、テーブル５０は正規の水平姿勢から若干持ち上げられた状態に留め置かれる。
これによりテーブル５０が正規にセットされていないことが判別できるが、この場合は、同図の矢線に示すように、テーブル５０を水平姿勢に向けて押し下げると、支え部材７０の当接部７１は、ストッパ７５を付勢力に抗して解除位置に回動させつつ傾斜面７６Ａの外面に沿って滑って係止部７６の内側に入り込み、テーブル５０が水平姿勢まで押されたところで、図１０に示すように、当接部７１が受け部６５に当たってテーブル５０が支持されるとともに、ストッパ７５が係止位置に戻って係止することになる。 When the operation of raising the table 50 is performed, when the operation portion 77 of the stopper 75 is not pressed, or the operation portion 77 is stopped from pressing before the contact portion 71 of the support member 70 is applied to the receiving portion 65. Since the stopper 75 is in the locking position, as shown in FIG. 11, when the contact portion 71 of the support member 70 is to be brought into contact with the receiving portion 65, the contact portion 71 is obstructed by the locking portion 76. As a result, the table 50 remains outside the inclined surface 76A, and the table 50 is kept slightly lifted from the normal horizontal posture.
As a result, it can be determined that the table 50 is not properly set. In this case, as shown by the arrow in FIG. 10, slides along the outer surface of the inclined surface 76 A while rotating the stopper 75 against the urging force and enters the inside of the locking portion 76, and when the table 50 is pushed to the horizontal position, FIG. As shown in FIG. 5, the abutting portion 71 hits the receiving portion 65 to support the table 50, and the stopper 75 returns to the locking position and is locked.

テーブル５０が水平姿勢に正規にセットされたら、扉２４を開けてホテルパンＰを温蔵室２０または冷蔵室２１から出し、天板１４からテーブル５０の上面にわたって載せ、同上面を利用して料理を食器に盛り付ける。
テーブル５０が起こされている状態において、人がぶつかる等でテーブル５０が意図しないところで持ち上げられると、支え部材７０の当接部７１が落下しようとするが、図１２に示すように、当接部７１が係止部７６の傾斜面７６Ａの内面に係止されてそれが阻止され、支え部材７０ひいてはテーブル５０が落下することが防止される。テーブル５０が自重で水平姿勢に戻ったところで、支え部材７０の当接部７１が再び受け部６５に当たり、テーブル５０は同姿勢に再び支持される（図１０）。 When the table 50 is properly set in a horizontal position, the door 24 is opened and the hotel pan P is taken out from the warm room 20 or the cold room 21, placed on the top surface of the table 50 from the top plate 14, and the upper surface is used for cooking. On the tableware.
When the table 50 is raised and the table 50 is lifted where it is not intended, such as when it hits a person, the abutting portion 71 of the support member 70 tends to fall. However, as shown in FIG. 71 is locked to the inner surface of the inclined surface 76A of the locking portion 76 to prevent it, and the support member 70 and thus the table 50 are prevented from falling. When the table 50 returns to the horizontal posture due to its own weight, the contact portion 71 of the support member 70 again hits the receiving portion 65, and the table 50 is again supported in the same posture (FIG. 10).

テーブル５０を畳む場合は、図１３に示すように、ストッパ７５の操作部７７を押して解除位置に回動させつつ、テーブル５０の回動端側を掴んで所定角度引き上げると、このときはストッパ７５の係止部７６が受け部６５の外側を開放しているから、支え部材７０の当接部７１が受け部６５から外れたのち係止部７６の外側を通って、自重により垂下姿勢に戻る。引き続いてテーブル５０の回動端を掴んだ手を離すと、テーブル５０も垂下姿勢に畳まれる。 When the table 50 is folded, as shown in FIG. 13, the operating portion 77 of the stopper 75 is pushed and rotated to the release position, and the table 50 is held at the rotating end side and pulled up by a predetermined angle. Since the engaging portion 76 of the support member 65 opens the outside of the receiving portion 65, the contact portion 71 of the support member 70 is detached from the receiving portion 65, passes through the outside of the engaging portion 76, and returns to the hanging posture by its own weight. . Subsequently, when the hand holding the rotation end of the table 50 is released, the table 50 is also folded into the hanging posture.

このように本実施形態では、ストッパ７５を常には係止位置に回動付勢する構成としたから、いわゆるストッパ７５の掛け忘れが発生せず、不用意にテーブル５０が畳まれる事態が生じることを確実に防止できる。意図的にテーブル５０を起こしたり畳むときは、ストッパ７５の操作部７７を押して解除位置に回動させる必要があるが、このストッパ７５の操作部７７を押圧する操作は、テーブル５０を回動させるときに必須となる回動端を掴む操作と併せて行うことができ、操作性にも優れたものとなる。 Thus, in this embodiment, since the stopper 75 is always configured to be urged to rotate to the locking position, the so-called forgetting to apply the stopper 75 does not occur and the table 50 is folded inadvertently. Can be surely prevented. When the table 50 is intentionally raised or folded, it is necessary to push the operating portion 77 of the stopper 75 and turn it to the release position. However, the operation of pressing the operating portion 77 of the stopper 75 turns the table 50. It can be performed together with the operation of grasping the pivot end, which is sometimes essential, and is excellent in operability.

また、ストッパ７５の係止部７６を、鋭角の斜め姿勢に折り返した形状としたから、以下のような利点が得られる。
ストッパ７５を係止位置に留めたままにテーブル５０を起こす操作を行った場合は、支え部材７０の当接部７１を受け部６５に当てようとした場合にも、当接部７１が係止部７６で邪魔されてその傾斜面７６Ａの外側に留まり、テーブル５０は正規の水平姿勢から若干持ち上げられた状態に留め置かれ、かつ係止もされない。しかしその場合は、テーブル５０を水平姿勢に向けて押し下げると、支え部材７０の当接部７１は、ストッパ７５を付勢力に抗して解除位置に回動させつつ傾斜面７６Ａの外面に沿って滑って係止部７６の内側に入り込み、テーブル５０が水平姿勢まで押されたところで、当接部７１が受け部６５に当たってテーブル５０が支持されるとともに、ストッパ７５が係止位置に戻って係止がなされる。
すなわち、仮にストッパ７５の押圧操作を怠ってテーブル５０を正規にセットできなかったとしても、テーブル５０を水平姿勢に押し込むだけで、簡単にセットし直すことができる。 In addition, since the locking portion 76 of the stopper 75 has a shape that is folded back into an acute angle, the following advantages are obtained.
When the operation of raising the table 50 is performed with the stopper 75 held in the locking position, the contact portion 71 is locked even when the contact portion 71 of the support member 70 is to be brought into contact with the receiving portion 65. The table 50 is obstructed by the portion 76 and stays outside the inclined surface 76A, and the table 50 is kept slightly lifted from the normal horizontal posture and is not locked. However, in that case, when the table 50 is pushed down toward the horizontal position, the contact portion 71 of the support member 70 rotates along the outer surface of the inclined surface 76A while rotating the stopper 75 to the release position against the urging force. When the table 50 is pushed to the horizontal position by sliding, the table 50 is pushed to the horizontal position, the contact portion 71 comes into contact with the receiving portion 65, the table 50 is supported, and the stopper 75 is returned to the locking position and locked. Is made.
In other words, even if the table 50 cannot be properly set due to neglecting the pressing operation of the stopper 75, it can be easily reset only by pushing the table 50 into the horizontal posture.

＜実施形態２＞
次に、本発明の実施形態２を図１４ないし図１９によって説明する。実施形態２は、上記実施形態１に対して、特にストッパ９０の係止部９１の形状に変更を加えたものである。以下、主に変更部分を中心に説明し、実施形態１と同一機能を有する部位については、同一符号を付すことで重複した説明は省略する。
上記の実施形態１では、図１８に示すように、ストッパ７５の係止部７６が鋭角の斜め姿勢に折り返した形状となっているから、仮に支え部材７０の当接部７１がストッパ７５の係止部７６の外側にセットされてしまった場合にも、テーブル５０を押し下げれば、ストッパ７５を付勢力に抗して回動させつつ、当接部７１を係止部７６の内側に導くことが可能となっている。 <Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the shape of the locking portion 91 of the stopper 90 is particularly changed with respect to the first embodiment. Hereinafter, the description will be mainly focused on the changed portion, and portions having the same functions as those of the first embodiment will be denoted by the same reference numerals, and redundant description will be omitted.
In the first embodiment, as shown in FIG. 18, since the locking portion 76 of the stopper 75 is folded back into an acute angle, the contact portion 71 of the support member 70 is temporarily engaged with the stopper 75. If the table 50 is pushed down even if it has been set outside the stop 76, the stopper 75 is rotated against the urging force and the contact portion 71 is guided inside the locking portion 76. Is possible.

上記構造の場合、ストッパ７５の係止部７６が、受け部６５の突出部６５Ｂと干渉することなく回動させるには、突出部６５Ｂの先端と、係止部７６の付け根との間の隙間Ｓｘを大きく取る必要があり、ひいては回動軸８２から係止部７６の付け根までの長さＬｘも長くなる。
このようにストッパ７５の係止部７６までの長さＬｘが長いと、例えば図１７の鎖線に参照して示すように、テーブル５０を持ち上げることにより支え部材７０の当接部７１を係止部７６の外側を通過させつつ落下させる場合に、係止部７６を当接部７１と干渉しないようにその軌道Ｋの外に外すためには、テーブル５０を大きく持ち上げる必要がある。そうするとその分、テーブル５０と天板１４との間の隙間が大きくなる嫌いがある。 In the case of the above structure, in order for the locking portion 76 of the stopper 75 to rotate without interfering with the protruding portion 65B of the receiving portion 65, a gap between the tip of the protruding portion 65B and the root of the locking portion 76 is used. It is necessary to increase Sx, and as a result, the length Lx from the rotation shaft 82 to the root of the locking portion 76 also increases.
When the length Lx of the stopper 75 to the locking portion 76 is long as described above, for example, as shown with reference to the chain line in FIG. When dropping while passing the outside of 76, it is necessary to lift the table 50 greatly in order to remove the locking portion 76 from the track K so as not to interfere with the contact portion 71. If it does so, there is a dislike that the clearance gap between the table 50 and the top plate 14 becomes large.

また、突出部６５Ｂと係止部７６の隙間Ｓｘが広いと、図１８の係止状態でテーブル５０が無理に持ち上げられたときに、当接部７１が隙間Ｓｘを通って受け部６５の下側に潜り込んでしまう可能性もあった。
尤も、比較例としての図１９に示すように、係止部Ｙを例えば直角曲げする等の傾斜の小さいものにすれば、突出部６５Ｂと係止部Ｙの隙間Ｓｙが狭く、また係止部Ｙまでの長さＬｙが短くできるため、上記した懸念は一掃されるが、支え部材７０の当接部７１を係止部Ｙの内側に自動的に導入する機能が果たし辛くなる。 Further, if the gap Sx between the protruding portion 65B and the locking portion 76 is wide, when the table 50 is forcibly lifted in the locked state of FIG. 18, the contact portion 71 passes under the receiving portion 65 through the gap Sx. There was also the possibility of getting into the side.
However, as shown in FIG. 19 as a comparative example, if the locking portion Y has a small inclination such as bending at right angles, the gap Sy between the protrusion 65B and the locking portion Y is narrow, and the locking portion Since the length Ly to Y can be shortened, the above-mentioned concerns are eliminated, but the function of automatically introducing the contact portion 71 of the support member 70 into the locking portion Y becomes difficult to perform.

そこでこの実施形態２では、ストッパ９０の係止部９１の形状を、図１６に示すように、下側のほぼ半分の高さ部分が、ストッパ９０から上面側に直角に立ち上がった垂直面９２で、上側が実施形態１と同じ角度で折り返された傾斜面９３となるように形成されている。
その結果、ストッパ９０の係止部９１が、受け部６５の突出部６５Ｂと干渉することなく回動させるには、突出部６５Ｂの先端と、係止部９１の付け根との間の隙間Ｓが実施形態１よりも狭くでき、ひいては回動軸８２から係止部９１の付け根までの長さＬも実施形態１よりも短くできる。 Therefore, in the second embodiment, as shown in FIG. 16, the shape of the locking portion 91 of the stopper 90 is such that the lower half of the height portion is a vertical surface 92 that rises perpendicularly from the stopper 90 to the upper surface side. The upper surface is an inclined surface 93 that is folded back at the same angle as in the first embodiment.
As a result, in order for the locking portion 91 of the stopper 90 to rotate without interfering with the protruding portion 65B of the receiving portion 65, a gap S between the tip of the protruding portion 65B and the base of the locking portion 91 is formed. The length L can be narrower than that of the first embodiment, and the length L from the rotation shaft 82 to the base of the locking portion 91 can also be shorter than that of the first embodiment.

この実施形態２のストッパ９０の係止部９１の構造によれば、上側の傾斜面９３を利用して、支え部材７０の当接部７１を係止部９１の内側に自動的に導入する機能を果たすことができる。
その上で、ストッパ９０の係止部９１までの長さＬが比較的短くできるから、図１７の実線に示すように、テーブル５０を持ち上げる量を比較的小さく抑えても、係止部９１を当接部７１の軌道Ｋの外側に外すことが可能となる。その結果、テーブル５０と天板１４との間の隙間を小さく抑えることができる。 According to the structure of the locking portion 91 of the stopper 90 of the second embodiment, the function of automatically introducing the contact portion 71 of the support member 70 into the locking portion 91 using the upper inclined surface 93. Can be fulfilled.
In addition, since the length L of the stopper 90 to the locking portion 91 can be made relatively short, as shown by the solid line in FIG. 17, the locking portion 91 can be moved even if the amount of lifting the table 50 is kept relatively small. The contact portion 71 can be removed outside the track K. As a result, the gap between the table 50 and the top plate 14 can be kept small.

さらに、突出部６５Ｂと係止部９１の隙間Ｓが比較的狭くできるから、図１６の係止状態からテーブル５０が無理に持ち上げられたときにも、当接部７１が隙間Ｓを通って受け部６５の下側に潜り込むことが防がれる。
なお、図１４及び図１５に示すように、受け部６５の突出部６５Ｂにおけるストッパ９０の係止部９１に係止される領域Ｂ以外の領域Ａで、その突出縁９５を係止部９１との間に隙間が無くなる程度に突出させてやると、当接部７１が受け部６５の下側に潜り込むことをより確実に防止することができる。 Further, since the gap S between the projecting portion 65B and the locking portion 91 can be made relatively narrow, even when the table 50 is forcibly lifted from the locked state of FIG. It is possible to prevent the underside of the portion 65 from entering.
As shown in FIGS. 14 and 15, the protruding edge 95 is connected to the locking portion 91 in the region A other than the region B locked to the locking portion 91 of the stopper 90 in the protruding portion 65 B of the receiving portion 65. If the protrusions are protruded to such an extent that there is no gap between them, it is possible to more reliably prevent the contact part 71 from entering the lower side of the receiving part 65.
