  By the way, the furniture leg having the columnar leg body as described above is fastened and fixed while turning the fixing screw around the shaft, so that all directions can be set to the front, so the fixing screw can be used as a mounting washer. Even if the leg body is turned and fixed so as to be screwed, no problem occurs.

  However, as a user's request, in addition to a furniture leg having a columnar leg body, there may be a desire for a furniture leg having a square pillar shape with a square cross section or a leg body with an irregular cross section. When the furniture leg of the leg body having such a prismatic shape or an irregular cross section is formed by providing a screw-type fixing screw on the upper part, the following problems occur.

  That is, a furniture leg having a prism main body or a leg body having an irregular cross section may be limited to a flat surface of a prism or a specific portion in front of the furniture leg. In order to fix to the bottom of the base, fit the fixing screw (bolt) protruding from the top to the mounting washer on the bottom of the furniture, turn the leg body completely and screw in the fixing screw, and fix it to a specific surface such as the flat surface of the prism When the portion comes to the front, the furniture leg is not always fixed completely, and there arises a problem that the surface is fixed to the front surface of the furniture other than the front surface of the leg.

  Therefore, a furniture leg having a leg body having such a prismatic or odd-shaped cross section is provided with a flange-shaped fixing seat portion instead of a fixing screw at the upper portion of the furniture leg, and the fixing seat portion is perforated. It is common to fix a leg to the bottom of furniture using a plurality of fixing holes and wood screws.

  However, when furniture is sold and installed in a customer's house, etc., it is carried in with the legs removed so that the legs are not damaged when the furniture is brought in, and the furniture legs are attached to the bottom of the furniture at the carry-in location. In such a case, the work of screwing and fixing three or four wood screws to one leg is necessary at the place where the furniture is carried in, and there is a problem that the installation work becomes complicated. there were.

  The present invention solves the above-described problem, and in a furniture leg fixed to furniture using a fixing screw protruding at the top, the leg is set to the furniture with an arbitrary surface aligned with the front of the furniture. An object of the present invention is to provide a furniture leg that can be easily fixed and has good mounting workability.

  In order to solve the above-described problems, the furniture leg of the present invention has a leg main body having a fixing screw projecting upward at an upper end portion thereof and a female screw portion provided at a lower end portion thereof, and engaged with the leg main body. The cover body is attached to the outer side of the leg body so as to be engageable via the portion and rotatable within a predetermined angle range, and is attached to the upper opening provided at the upper end of the cover body. And a fixing foot that is screwed and attached to the lower end of the leg main body so as to be height-adjustable, and is provided at the bottom of the furniture. After the fixing screw is screwed into the female screw portion at the bottom of the furniture, the cover body is turned to the anti-screwing side, and the adjustment body is held with the adjusting foot in an appropriate state. The leg main body is turned to fasten and fix the fixing screw.

  Here, the leg main body and the cover body are part of the outer peripheral part of the leg main body and the part of the inner side of the cover body corresponding thereto as the engaging part that is rotatably engaged only within a predetermined angle range. In addition, the convex portion and the concave portion can be provided to be engageable with each other.

  The leg body may be formed in a substantially truncated cone shape, and the cover body may be formed in a substantially truncated pyramid shape.

  Since such a furniture leg is provided at the bottom of the furniture, the fixing screw at the upper end of the leg main body can be screwed into the screw part and fixed by a simple operation. On the other hand, the fixing screw is temporarily attached to the bottom of the furniture. After screwing into the threaded part, turn the leg body with the adjustment foot and tighten the fixing screw to the female threaded part while turning the cover body to the anti-screwing side so that the orientation of the cover body is appropriate. Even if the leg of the leg for furniture, that is, the leg of the cover body has a polygonal cross section or a deformed cross section with a specific surface, the leg can be fixed with the front face coinciding with the front face of the furniture. Therefore, for example, even a leg having a quadrangular pyramid-shaped outer shape, the flat surface serving as the front surface thereof can be easily fixed to the front surface of the furniture according to suitability.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of a furniture leg, and FIG. 2 shows an exploded perspective view thereof. This furniture leg is a furniture leg that is fastened and fixed to a mounting washer K1 provided as a female screw portion at the bottom of the furniture K using a fixing screw 11 protruding at the top. An upper part of the leg body 1 is projected upward. A cover body 2 is fitted on the outer peripheral portion of the leg main body 1 so as to be engageable via an engaging portion and rotatable within a predetermined angle range. It is mounted adjustable.

  As shown in FIGS. 2 and 4, the leg body 1 is formed in a substantially truncated cone shape having a large diameter on the top and a small diameter on the bottom, and the outer peripheral surface of the truncated cone has a range of 0 ° to 90 °. In the range of 180 ° to 270 °, the circumferential convex portion 13 is formed as the engaging portion so as to bulge out to a small thickness on the outer peripheral portion. That is, the circumferential convex portion 13 is formed in a range of 90 ° at a symmetrical position around the axis.

  On the other hand, the circumferential recess 12 is formed in the range of 90 ° to 180 ° and the range of 270 ° to 360 ° on the outer peripheral surface of the truncated cone. That is, the circumferential concavity 12 is formed by removing portions of the frustoconical outer peripheral surface in the range of 90 ° to 180 ° and in the range of 270 ° to 360 ° in layers. In the circumferential recess 12 removed in layers in the 90 ° range, a convex rib 22 on the inner side of the cover body 2 described later is disposed as the other engaging portion, and the cover body within the 90 ° angle range. 2 can be rotated. On the other hand, when the cover body 2 is turned clockwise and the fixing screw 11 of the leg main body 1 is screwed into the bottom of the furniture, the convex rib 22 engages with the end of the circumferential convex portion 13 of the leg main body 1 and the leg main body 1. The power is transmitted to and will be turned.

  Further, a bolt serving as a fixing screw 11 is embedded in the center of the upper end portion of the leg main body 1 with the thread portion protruding upward. Further, a cylindrical recess 15 is formed on the bottom surface of the lower end portion of the leg main body 1, and a driving nut 14 is embedded as a female screw portion thereabove. An adjustment screw 31 of an adjustment foot 3 to be described later is screwed into the driving nut 14 so that the height can be adjusted, and a cylindrical portion 32 of the adjustment foot 3 enters the cylindrical recess 15. The leg body 1 can be molded from a synthetic resin such as ABS resin. In this case, the fixing screw 11 can be attached to a fixed position by insert molding as an insert.

  As shown in FIGS. 2 and 5, the cover body 2 is formed in a substantially regular quadrangular pyramid shape, a cross section and an upper surface are formed in a square shape, and a rectangular opening 23 is formed therein. A substantially circular circular opening 24 is formed at the lower end of the cover body 2, and a conical hollow portion 21 is formed inside the cover body 2. Further, at two locations on the inner peripheral surface of the conical hollow portion 21 of the cover body 2 that are opposed to each other centering on the axis, convex ribs 22 serving as the engaging portions are axially positioned at opposing positions on the inner peripheral surface. Are formed along.

  The conical hollow portion 21 is formed corresponding to the outer shape of the leg main body 1 described above, and the leg main body 1 is inserted into the conical hollow portion 21 from the rectangular opening 23 at the top of the cover body 2, that is, a cover. The body 2 can be inserted from the lower side of the leg body 1 into the conical hollow portion 21 so as to cover the outside of the leg body 1. A rectangular plate-like lid body 4 is fitted to the upper end portion of the cover body 2, that is, the rectangular opening portion 23. As shown in FIG. 2, a hole 42 through which the fixing screw 11 is passed is formed in the center of the lid body 4, and an annular recess 41 is formed around the hole 42. The cover body 2 and the lid body 4 can be formed of a synthetic resin.

  The adjustment foot 3 has a cylindrical portion 32 protruding from the center of the upper portion thereof, and an adjustment screw 31 protruding upward from the upper portion of the cylindrical portion 32. The adjustment screw 31 is formed using a bolt, and can be attached so that the head of the bolt is fitted into the cylindrical portion 32 and the screw portion protrudes upward, or the adjustment foot 3 is formed of a synthetic resin. The bolt adjusting screw 31 can be insert-molded as an insert.

  When assembling the furniture leg having the above-described configuration, as shown in FIG. 2, the leg body 1 is inserted into the conical hollow portion 21 of the cover body 2 from above, or the cover body 2 is covered from the lower side of the leg body 1. Then, the lid 4 is fitted into the rectangular opening 23 at the top of the cover 2 and the lid is closed. At this time, the convex rib 22 in the cover body 2 enters the circumferential recess 12 of the leg body 1, and the fixing screw 11 protrudes upward from the central hole 42 of the lid body 4.

  Next, the adjustment screw 31 of the adjustment foot 3 is inserted into the cover body from the circular opening 24 at the bottom of the cover body 2, and the adjustment screw 31 is screwed into the driving nut 14 of the inner leg body 1. At this time, a plain washer 33 is inserted into the adjustment screw 31. When the adjusting screw 31 is driven and screwed into the nut 14, the cylindrical portion 32 of the adjusting foot 3 enters the cover body 2, and the cylindrical portion 32 is fastened to the lower surface of the leg body 1 via the flat washer 33. . In this state, when the adjustment foot 3 is rotated while holding the cover body 2, the adjustment foot 3 and the leg main body 1 can rotate within a range of about 90 °. That is, since the convex ribs 22 in the cover body 2 are located in the circumferential concave portion 12 (90 ° angle range) of the leg body 1, the convex ribs 22 are arranged in the circumferential convex portion 13 as shown in FIG. The leg main body 1 and the cover body 2 can be relatively rotated within a range of about 90 ° until they reach the end of each other.

  As shown in FIGS. 7 and 8, the furniture leg configured as described above is attached to the bottom surface of the furniture K such as a TV stand or a side table by screwing a fixing screw 11. A mounting washer K1 is embedded in the bottom of the furniture K as an internal thread.

  First, while holding the cover body 2 and rotating it to the right, the fixing screw 11 at the upper end of the furniture leg is screwed into the mounting washer K1 on the bottom surface. When the screwed end is reached, the furniture leg is once stopped and locked to the bottom surface of the furniture K. At this time, there is no problem as long as the front surface of the cover body 2 of the pyramid-shaped furniture leg (usually a flat surface including one side of the square cross section) coincides with the front surface of the furniture K. The front of the furniture leg stops at an angle with respect to the front of the furniture.

  In such a case, hold the cover body 2 and turn the fixing screw 11 in the loosening direction (anti-screwing direction), that is, the anti-tightening direction (left direction) so that the front of the furniture leg faces the front of the furniture K. Manipulate. The rotation angle range in this case is a rotation range within 90 ° when the shape of the cover body 2 is a substantially quadrangular pyramid and the cross section is square. When the cover body 2 is rotated to the anti-clamping side, the cover body 2 rotates together with the leg body 1 and assumes a correct posture facing the front.

  Next, the leg 3 is held in the direction in which the leg body 1 is screwed (right direction), that is, in the tightening direction. At this time, if the adjustment foot 3 is turned with the other hand while holding the cover body 2 with one hand, only the leg body 1 in the cover body 2 rotates to the side to be screwed together with the fixing screw 11, and the leg body 1 is It is fastened and fixed by a fixing screw 11 through the lid 4.

  At this time, the leg main body 1 can be rotated within a range of about 90 ° within the cover body 2, and as described above, the angle is obtained by rotating leftward within 45 ° from the state in which the fixing screw 11 is first tightened and locked. After adjusting and loosening, it can be locked again by rotating at an angle of about 45 °. Thus, the furniture leg is fixed to the furniture K in a correct state in which the front surface of the cover body 2 on the outer surface of the furniture leg coincides with the front surface of the furniture K.

  In this way, first, the cover body 2 is turned and locked, and then the angle is adjusted so that the cover body 2 is slightly returned to the correct orientation according to the orientation of the cover body 2 according to the furniture. Therefore, the furniture leg can be properly oriented with respect to the furniture and can be fixed very easily.

  Thereafter, the same operation is performed, and usually four furniture legs are attached to one piece of furniture K. In such an attachment state, the adjustment foot 3 is in the shortest state, and the length of the leg is reduced. When it is necessary to adjust, when the adjustment foot 3 is held and turned to the left, the flat washer 33 fitted to the adjustment screw 31 slides, and the adjustment foot 3 rotates to the left together with the adjustment screw 31 on the upper side. The furniture leg is adjusted so that the length of the furniture leg is adjusted. As described above, the attachment of the furniture legs and the height adjustment of the legs can be performed simply by turning the cover body 2 or the adjustment foot 3.

  The cover body 2 has a quadrangular pyramid shape, but may be another polygonal frustum shape or a prism, and may have a shape in which the front surface and other surfaces are formed, such as an irregular cross section in which the front surface is specified. That's fine. Further, the circumferential concave portion provided on the outer periphery of the leg body as the engaging portion and the convex rib provided on the inner side of the cover body may be reversed, and the leg main body and the cover body are relatively in a predetermined angle range. It is sufficient if the engaging portion rotates in the direction.

  In the above embodiment, the adjusting foot 3 is formed of a synthetic resin. However, the adjusting foot can be integrally formed of a metal such as an aluminum alloy or a zinc alloy.
