を供する点にある。[Detailed description of the invention] In this invention, a locking rod a, which is always biased to protrude to the side of the support leg, is fitted on the support leg A so that it can move forward and backward, and the locking rod a can be freely pivoted on the upper end of the support leg A. The upper ends of the upper connecting rods 2 are pivotally connected to the top plate B, which is attached to the top plate B, and the locking holes 4a to which the locking rods a are to be engaged and disengaged are respectively connected.
, 5a, an actuating piece 5 attached to the lower end of the lower connecting rod 4 and the tip of the shelf C is pivotally attached 6 to the supporting leg A, and the upper connecting rod 2 and the lower connecting lever 4 are pivotally attached 7, and the lower connecting rod 4
An arcuate slot 8 is bored in the lower end of the actuating piece 5.
protrudingly provided with a protrusion 9 that slidably fits into the slot 8,
The upper end of the arm piece 10 for closing the locking hole 4a is pivotally attached to the lower connecting rod 4, and the lower connecting rod 4 is provided with a claw piece 12 that abuts against the arm piece 10. The purpose of the folding desk with a shelf is to provide an improved shelf with a simple structure that allows the folding desk with a shelf to be easily folded and unfolded, and also to be easily unlocked and locked. The point is that it provides a folding table.
図中１３は支脚Ａの上端に取付けられた支持金具で、そ
の先端に天板Ｂが枢着されている。In the figure, reference numeral 13 denotes a support metal fitting attached to the upper end of the support leg A, and the top plate B is pivotally attached to the tip of the support metal fitting.
１４は支脚Ａの下端に接合された水平部材、１５は同部
材１４に装架されたキャスタである。14 is a horizontal member joined to the lower end of the supporting leg A, and 15 is a caster mounted on the member 14.
また天＋／１ｌＥＢの両側に配設された一双の支脚Ａ間
には横桟（図示せず）が連結キれるものである。Further, horizontal beams (not shown) can be connected between a pair of supporting legs A arranged on both sides of the top +/11EB.
更に前記錠止杆ａの鍔片１６と支脚Ａとの間には弾機１
７が介装され、同弾機１７の弾撥力によって錠止杆ａは
常に支脚Ａの側方に突出するように賦勢されている。Furthermore, an ammunition 1 is provided between the collar piece 16 of the locking rod a and the supporting leg A.
7 is interposed, and the locking rod a is always urged to protrude to the side of the supporting leg A by the repulsive force of the ammunition 17.
本案に係る折畳机卓は前記のように構成されているので
、第１図に示す展開状態においては錠止杆ａは下部連杆
４及び棚Ｃに取付けられた作動片５の各錠止孔４ａ、５
ａに係合し、棚Ｃ及び下部連杆４は展開位置に錠止され
、不慮に机卓が折畳動作を行なう惧れかない。Since the folding desk according to the present invention is constructed as described above, in the unfolded state shown in FIG. Holes 4a, 5
a, the shelf C and the lower connecting rod 4 are locked in the unfolded position, and there is no risk that the table will be folded inadvertently.
なおこの際前記閉塞用腕片１０は錠止杆ａによって枢着
部１１を中心として上方に回動した位置に保持されて、
前記錠止孔４ａ、５ａを閉塞しないようになっている。At this time, the closing arm piece 10 is held in a position rotated upward about the pivot portion 11 by the locking rod a,
The locking holes 4a, 5a are not blocked.
この状態から前記机卓を折畳む場合、先ず錠止杆ａを引
張って後退させ、前記各錠止孔４ａ、５ａとの保合を解
除すると、同錠止孔の閉塞用腕片１０は自重によって枢
着部１１を中心として下方に回動して、第３図に示すよ
うに錠止孔４ａ、５ａを閉塞する。When folding the table from this state, first pull the locking rod a and move it back to release the locking holes 4a and 5a, then the closing arm piece 10 of the locking hole will be closed under its own weight. 3, the locking hole 4a, 5a is rotated downward about the pivot portion 11, thereby closing the locking holes 4a, 5a as shown in FIG.
従って錠止杆ａの引張力を解放すると、開錠止杆ａは弾
機１７の状勢力によって前進し、その先端が前記腕片１
０に衝接してそれ以上の前進を阻まれ、前記錠止孔４
ａ 、５ ａに嵌入することがない。Therefore, when the tensile force of the locking rod a is released, the locking rod a moves forward due to the force of the bullet 17, and its tip reaches the arm piece 1.
0 and is prevented from moving further, and the locking hole 4
a, 5a will not get stuck.
この状態より棚Ｃを支脚Ａに対する枢着部６を中心とし
て上方に回動させると、これに追随して作動片５も同方
向に回動し、作動片５の突子９が下部連杆４の弧状溝孔
８内を摺動してその下端縁を押圧し、下部連杆４を枢着
部６を中心として上方に回動せしめ、上下両連杆２，４
は枢着部７を中心としてくの字状に屈折し、天板Ｂは支
脚Ａに対する枢着部１を中心として下方に回動し始め、
爾後自重によって引続き回動し、第５図に示すように、
天板Ｂと棚Ｃとは支脚Ａに沿って折畳まれるものである
。From this state, when the shelf C is rotated upward around the pivot point 6 relative to the support leg A, the actuating piece 5 also rotates in the same direction, and the protrusion 9 of the actuating piece 5 connects to the lower connecting rod. 4 slides in the arcuate slot 8 and presses the lower edge thereof, causing the lower connecting rod 4 to rotate upward about the pivot joint 6, and connecting both the upper and lower connecting rods 2, 4.
is bent into a dogleg shape around the pivot part 7, and the top plate B begins to rotate downward around the pivot part 1 relative to the support leg A.
After that, it continues to rotate due to its own weight, and as shown in Figure 5,
The top plate B and the shelf C are folded along the supporting legs A.
而して前記のように棚Ｃの上方への回動に伴って下部連
杆４が枢着部６を中心として上方に回動する際、同連杆
４の爪片１２が前記閉塞用腕片１０を押圧して上方に回
動せしめるので、錠止片ａは前記腕片１０によって前進
を阻害されない。As described above, when the lower connecting rod 4 rotates upward about the pivot portion 6 as the shelf C rotates upward, the claw piece 12 of the connecting rod 4 engages the closing arm. Since the piece 10 is pressed and rotated upward, the forward movement of the locking piece a is not hindered by the arm piece 10.
なおこの際腕片１０は前進した錠止杆ａによって支持さ
れ、下方への回動を阻止される。At this time, the arm piece 10 is supported by the advanced locking rod a and is prevented from rotating downward.
そして下部連杆４が更に上方への回動運動を継続する際
、既に同下部連杆４の錠止孔４ａは錠止片ａとの係合位
置を外れているので、下部連杆４は錠止片ａの先端面を
摺動しながら回動する。When the lower link 4 continues its upward rotational movement, the locking hole 4a of the lower link 4 is already out of the engagement position with the locking piece a, so the lower link 4 It rotates while sliding on the tip surface of the locking piece a.
次に本案の机卓を折畳状態より展開する場合、第５図に
示す状態より天板Ｂを上方に回動すると、下部連杆４が
枢着部６を中心として下方に回動し、その弧状溝８の下
端縁が突子９を押上げ、棚Ｃを枢着部６を中心として下
方に回動せしめ、爾後棚Ｃは自重によって引続き下方に
回動し、突子９が弧状溝８内を摺動してその上端縁を押
圧して下部連杆４を圧下し、上下両連杆２，４が一直線
上に位置するように威勢し、天板Ｂは軽快に展開される
ものである。Next, when unfolding the desk of the present invention from the folded state, when the top plate B is rotated upward from the state shown in FIG. The lower edge of the arcuate groove 8 pushes up the protrusion 9, causing the shelf C to rotate downward about the pivot joint 6. After that, the shelf C continues to rotate downward due to its own weight, and the protrusion 9 pushes up the protrusion 9 into the arcuate groove. 8 and press its upper edge to push down the lower connecting rod 4, forcing the upper and lower connecting rods 2 and 4 to be positioned in a straight line, and the top plate B can be unfolded easily. It is.
なおこの際下部連杆４の上縁は上部連杆２の上縁に設け
たフランジ２ａに衝接し、同連杆２，４はこれ以上相対
回動運動を行なうことのないようになっている。At this time, the upper edge of the lower connecting rod 4 collides with the flange 2a provided on the upper edge of the upper connecting rod 2, so that the connecting rods 2 and 4 will no longer perform relative rotational movement. .
而して本案の机卓の展開位置において、前記突子９が棚
Ｃの自重によって弧状溝８の上端縁を押圧して、上下両
連杆２．４がくの字状に屈折するのを防止しているので
、天板Ｂは安定した展開状態に保持されるものである。Therefore, in the unfolded position of the table of the present invention, the protrusion 9 presses the upper edge of the arcuate groove 8 due to the weight of the shelf C, preventing the upper and lower connecting rods 2.4 from bending into a dogleg shape. Therefore, the top plate B can be maintained in a stable unfolded state.
また前記机卓の折畳時、前記したように前記閉塞用腕片
１０が錠止杆ａによって、上方に回動した位置に保持さ
れた状態のままで、下部連杆４と作動片５とが下方に回
動し、机卓が第１図に示す展開位置を占めたとき、錠止
杆ａが弾機１７の状勢力によって下部連杆４及び作動片
５の各錠止孔４ａ、５ａに自動的に嵌入し、机卓を展開
位置に錠止するものである。Further, when the desk is folded, the closing arm piece 10 is held in the upwardly rotated position by the locking rod a as described above, and the lower linking rod 4 and the operating piece 5 are connected to each other. When the table rotates downward and the table assumes the unfolded position shown in FIG. automatically engages the table and locks the table in the expanded position.
このように本案によれば、折畳時には錠止杆ａを後退さ
せて作動片５と下部連杆４に対する錠止を解除したのち
、棚Ｃを持上げるだけで、棚付き折畳机卓が軽快に而も
小容積に折畳まれ、また展開時には天板Ｂを持上げるだ
けで棚付き折畳机卓が軽快に展開されるとともに、自動
的に展開位置に錠止されるものである。In this way, according to the present invention, when folding, the locking rod a is moved back to release the lock on the actuating piece 5 and the lower connecting rod 4, and then the shelf C is lifted up, and the folding desk table with the shelf is folded. It can be folded easily and into a small volume, and when unfolding, the folding desk with a shelf can be easily unfolded by simply lifting the top plate B, and it is automatically locked in the unfolded position.
