Description
【0001】[0001]
本考案は、テーブル等の高さと水平を調節するための、外観の良好な高さ調節 装置に関するものである。 The present invention relates to a height adjusting device having a good appearance for adjusting the height and level of a table or the like.
【0002】[0002]
テーブル等の高さと水平を調節するための従来の高さ調節装置は、通常、角筒 状の脚杆の下端に、中心に垂直の螺孔を設けた調節具を嵌合するとともに、螺孔 に、円板状の脚座の上面中央に突設した螺杆を螺挿し、脚座を回転させて高さ調 節を行なうようになっている(実開昭48−10759号公報参照)。 A conventional height adjusting device for adjusting the height and the horizontal of a table or the like is usually such that an adjusting tool having a vertical screw hole at the center is fitted to the lower end of a rectangular rod, and a screw hole is formed. A screw rod projecting from the center of the upper surface of the disc-shaped leg seat is screwed into it and the leg seat is rotated to adjust the height (see Japanese Utility Model Laid-Open No. 48-10759).
【0003】[0003]
しかし従来の装置では、長期使用により、調節具から伝わる荷重によって、脚 杆の下端開口部が拡開したり、調節具が縮小したりして、調節具が脚杆より脱落 することがある。 However, in the conventional device, due to the load transmitted from the adjuster, the lower end opening of the leg rod may be widened or the adjuster may be contracted due to the load transmitted from the adjuster, and the adjuster may fall off the leg rod.
【0004】 本考案は、このような不都合が起こらず、しかも、外観の良好な高さ調節装置 を提供することを目的としている。An object of the present invention is to provide a height adjusting device which does not cause such inconvenience and has a good appearance.

本考案は、両側面に上下方向の凹溝を形成した角筒状の脚杆の下端に、上下方 向を向き、下端に前記脚杆の下端に当接するフランジを有するとともに、このフ ランジの上面両側部に、前記凹溝に係合しうる上向きの係合片を突設し、かつフ ランジの下面より垂直の螺孔が穿設された調節具を嵌設し、この調節具の前記螺 孔に、円板状をなす脚座の上面中央に立設した螺杆を螺挿したことにより、上述 の課題の解決を図っている。 According to the present invention, the lower end of a rectangular rod having a vertical groove on both sides faces upward and downward, and the lower end has a flange that abuts against the lower end of the rod. On both sides of the upper surface, an upward engaging piece that can engage with the groove is projected, and an adjusting tool having a vertical screw hole is inserted from the lower surface of the flange. The above-mentioned problem is solved by inserting a screw rod standing upright in the center of the upper surface of the disk-shaped leg seat into the screw hole.

【作用】 本考案の装置は、従来の装置と同様に脚座を回転させることにより、テーブル 等の高さは調節される。In the device of the present invention, the height of the table or the like is adjusted by rotating the leg seat as in the conventional device.
【0007】 調節具のフランジの上面両側に突設した上向きの係合片を、脚杆の両側面に形 成した凹溝に係合させることにより、本装置を長期使用して、脚杆内の調節具が 弛んでも、脚杆を両側より挟む係合片が、調節具のがたつきを防止して、脚杆よ りの脱落を防止する。[0007] By engaging the upward engaging pieces projecting on both sides of the upper surface of the flange of the adjuster with the concave grooves formed on the both sides of the leg rod, the device can be used for a long time and the inside of the leg rod can be protected. Even if the adjustment tool is loosened, the engaging pieces that sandwich the leg rod from both sides prevent the adjustment tool from rattling and prevent it from falling off the leg rod.

図面は、本考案の一実施例を示すもので、図示を省略したテーブルにおけるほ ぼ角筒状をなす脚杆(1)の左右両側面(以下左右方向は図面についていう)には、 その全高にわたって、上下方向の凹溝(2)(2)が形成され、かつ脚杆(1)の下端 には、合成樹脂製の調節具(3)が嵌設されている。 The drawings show an embodiment of the present invention, in which the left and right side surfaces (hereinafter, the left and right directions refer to the drawings) of the substantially rod-shaped leg rod (1) of the table (not shown) have the entire height. A vertical recessed groove (2) (2) is formed thereover, and an adjusting tool (3) made of synthetic resin is fitted on the lower end of the leg rod (1).
【0009】 調節具(3)は、平面形がほぼ脚杆(1)の外面形とほぼ同形同寸のフランジ(8) の上面に、平面形が脚杆(1)の内面形と同形で、かつそれより若干小寸の有底の 筒状部(4)を立設したものである。 筒状部(4)の内側の中心より若干右寄りの個所には、柱状部(5)が立設され、 柱状部(5)の中心には、螺孔(6)が貫設されている。The adjusting tool (3) has the same planar shape as that of the outer surface of the leg rod (1), and the planar shape of the adjusting member (3) has the same shape as the inner surface of the leg rod (1). In addition, the bottomed cylindrical portion (4), which is slightly smaller than that, is erected. A columnar portion (5) is erected at a position slightly to the right of the inner center of the tubular portion (4), and a screw hole (6) is formed at the center of the columnar portion (5).
【0010】 筒状部(4)の外周面には、上下方向を向く複数の突条(7)が突設されている。On the outer peripheral surface of the tubular portion (4), a plurality of protruding ridges (7) directed in the up-down direction are provided in a protruding manner.
【0011】 フランジ(8)の上面左右両側部には、前後方向を向く係合片(9)(9)が突設さ れている。Engaging pieces (9) and (9) facing in the front-rear direction are provided on both left and right sides of the upper surface of the flange (8) in a protruding manner.
【0012】 フランジ(8)の下面左端には、内面が上記螺孔(6)を中心として弧状に湾曲す るとともに、螺孔(6)側が開口する保護縁(10)が垂設されている。保護縁(10)の 前後外周面には、上下方向を向く複数の小突条(11)が突設されている。At the left end of the lower surface of the flange (8), an inner surface is curved in an arc shape around the screw hole (6), and a protective edge (10) which is open at the screw hole (6) side is vertically provided. . On the front and rear outer peripheral surfaces of the protective edge (10), a plurality of small ridges (11) directed in the up-down direction are provided in a protruding manner.
【0013】 上記筒状部(4)を脚杆(1)の下端に嵌入して、外周面の突条(7)(7)を脚杆( 1)の内面に圧接させ、かつフランジ(8)を脚杆(1)の下端面に当接し、各係合 片(9)を脚杆(1)の凹溝(2)の下端に係合させることにより、調節具(3)は、保 護縁(10)を外側方として、脚杆(1)に回動不能に取付けられる。The tubular portion (4) is fitted into the lower end of the leg rod (1) so that the protrusions (7) and (7) on the outer peripheral surface are pressed against the inner surface of the leg rod (1) and the flange (8) ) Is brought into contact with the lower end surface of the leg rod (1) and each engaging piece (9) is engaged with the lower end of the groove (2) of the leg rod (1), so that the adjusting tool (3) is retained. The guard edge (10) is outwardly mounted on the leg rod (1) in a non-rotatable manner.
【0014】 螺孔(6)には、下方より、水平をなす円板状の脚座(12)の上面中央に立設した 螺杆(13)が螺挿される。 なお、脚座(12)の半径は、螺孔(6)を中心とする保護縁(10)の内径より小径で あり、かつその厚さは、保護縁(10)の高さより若干厚くなっている。A screw rod (13) which is erected on the center of the upper surface of a horizontal disc-shaped leg seat (12) is screwed into the screw hole (6) from below. The radius of the leg seat (12) is smaller than the inner diameter of the protective edge (10) centered on the screw hole (6), and its thickness is slightly thicker than the height of the protective edge (10). There is.
【0015】 上述の本考案装置において、脚座(12)を回転させることにより、テーブルの高 さが調節される。In the above-mentioned device of the present invention, the height of the table is adjusted by rotating the leg seat (12).
【0016】 また、脚杆(1)の両側の凹溝(2)に係合する調節具(3)の係合片(9)(9)が、 脚杆(1)を両側より挟持して、本装置の長期使用による調節具(3)のがたつきや 脚杆(1)よりの脱落を防止する。Further, the engaging pieces (9) (9) of the adjusting tool (3) which engage with the concave grooves (2) on both sides of the leg rod (1) hold the leg rod (1) from both sides. Prevents rattling of the adjustment tool (3) and falling off of the leg rod (1) due to long-term use of this device.
【0017】[0017]
(a) 調節具の両側部における係合片が、脚杆の両側における凹溝に係合して 、脚杆を両側より挟持しているので、本装置を長期使用しても、調節具が脚杆内 でがたついて脱落することはない。 (a) Since the engaging pieces on both sides of the adjuster engage with the concave grooves on both sides of the leg rod to clamp the leg rod from both sides, the adjuster can be used even if this device is used for a long period of time. It does not rattle within the rod and fall off.
【0018】 (b) テーブル等の使用時や移動時に、脚杆と調節具との間に加わる水平方向 の回転力や、前後左右方向からのこじり力に対して、脚杆の内面に当接する調節 具の外側面との抵抗力に加えて、フランジの上面両側の係合片と脚杆の外側面と の係合による抵抗力が作用するため、従来の装置と比較して、脚杆と調節具との 取付状態を、きわめて強固に維持することができる。(B) When the table or the like is used or moved, it comes into contact with the inner surface of the leg rod against a horizontal rotational force applied between the leg rod and the adjuster or a twisting force from the front, rear, left and right directions. In addition to the resistance force with the outer side surface of the adjuster, the resistance force due to the engagement between the engaging pieces on both sides of the upper surface of the flange and the outer side surface of the leg rod acts, so compared with the conventional device, It is possible to maintain the mounting condition with the adjustment tool extremely firmly.
【0019】 (c) 調節具の係合片は、脚杆の両側面の凹溝に係合しているため、使用中の 調節具への衝撃に対して、脚杆の隅部が係合片を保護し、係合片の破損は防止さ れる。(C) Since the engaging pieces of the adjuster are engaged with the concave grooves on both side surfaces of the leg rod, the corners of the leg rod are engaged with each other against the impact on the adjuster in use. It protects the pieces and prevents the engagement pieces from breaking.
