Description

  The present invention relates to a table leg fixture and a table assembled by using this fixture, and in particular, allows the leg body to be accurately aligned with the corners of the top plate and is permanently attached. It is an object of the present invention to provide a fixture and a table suitable for obtaining a high bonding strength.

  Previously, the present applicant has developed a mounting bracket for a table leg shown in Patent Documents 1 and 2 below. This mounting bracket includes a top plate side metal fitting as a receiver fitted and fixed in a recess formed on the lower surface of the top plate, and a leg side metal fitting fixed to the upper portion of the leg body. By fitting the upper parts of the side metal parts and connecting both metal parts via attachment screws, the legs are connected and fixed to the lower part of the top plate via the attachment metal parts.

  According to these mounting brackets, legs can be directly attached to the top plate, so there is no need for a complicated mounting structure such as attaching the curtain plate to the outer periphery of the lower surface of the conventional top plate and attaching the legs to its four corners. There is an advantage that a simple structure can be obtained structurally and in design.

  By the way, as a recent trend in this type of table, as an example, when chamfering processing such as R-surface shape is performed at the four corners of the top plate, and a part of the body such as the head collides with the corner of the top plate In addition to the safety of the above, the novelty of the design with a soft curved surface is obtained, and the leg body also has a round bar shape with a diameter equal to the R surface shape according to the chamfering processing of the corner part on the leg side, In some cases, it is required to have a vertical shape that is continuous with the lower part of the corner and on a straight line, but there is a processing error in the position of the mounting holes for embedding the brackets on the four corners of the lower surface of the top plate. If it is, the upper end of the leg may protrude outward from the corner of the top plate. In such a case, even if it protrudes slightly, it does not look good, and it is determined as a defective product, which causes a decrease in yield at the finishing stage.Therefore, it is necessary to increase the accuracy of the processing position of the mounting hole of the receiving bracket. there were.

  Therefore, in Patent Document 3 below, a fixture having an adjusting mechanism for preventing the protrusion of the pedestal due to a processing error has been developed. In this structure, in a state where the fixing screws are loosened, the receiving metal fittings constituting the top plate side metal fittings fixed to the table top plate and the holding metal fittings to which the legs are fixed can be relatively moved. In the tightened state, the top plate side bracket is clamped and fixed between the clamp bracket and the flange of the leg bracket on the top of the leg, so that the leg can be fixed to the bottom of the top plate so that it can be moved and adjusted. It has the advantage that it can prevent a decrease in appearance due to an attachment position error or the like.

  However, in this structure, the clamping force is applied only by the fastening force of the screw against the rotation of the leg and the horizontal displacement. Basically, the joint between the flange and the clamping bracket and the receiving bracket is applied. Since the surfaces are metal-to-metal bonds and are joined in a horizontal plane, the frictional force is small, and if the screws loosen slightly due to external forces, the joints are easily loosened and the initial fastening force is maintained. There was a problem that it was difficult to do. In particular, when a prismatic leg is attached to the corner of the square top plate, if the leg rotates due to looseness, the line between the leg of the prism and the corner of the top plate will shift. There was also a problem in terms of aesthetics.

The present invention solves the above-described problems, and the object of the present invention is to provide a high initial fastening force and maintain the fastening force once the top plate and the legs are fastened together using a mounting screw. It is possible to provide a table leg mounting tool that can prevent the deviation of the mounting position of the leg body after the passage of time.
It is another object of the present invention to provide a table in which the top plate and the legs are accurately coupled by a simple assembling operation without making a mistake in the mounting directionality of the above-described fixtures.

In order to achieve the above-mentioned object, the table leg mounting tool according to the present invention is formed on the disk-shaped receiving metal 1 attached to the four corners of the lower surface of the rectangular table top plate 6 and the lower surface of the table top plate 6. Inside the mounting holes 60 and 61, the clamping metal fitting 2 arranged on the upper surface of the receiving metal fitting 1 and the upper center of the table leg 7 are inserted and fixed, and the head 32 is projected to the top via the positioning flange 31. A leg-side metal fitting 3 and a mounting screw 4 are provided. The bracket 1 includes a flange portion 10 around the disk, a sandwiching portion 11 that is formed one step thinner inside the flange portion 10, and a long hole 12 that is formed in a substantially strip-shaped square hole formed in the center of the sandwiching portion 11. It has. The holding metal fitting 2 has a substantially short cylindrical shape with a flat bottom surface, a receiving hole 21 penetrating vertically in the center, and a screw block 22 projecting on one side of the flat bottom surface. The screw hole 23 is formed obliquely through the screwing block 22 and one end thereof communicates with the receiving hole 21. The clamping metal fitting 2 is held loosely in the upper surface 11a of the clamping part 11 of the metal fitting 1 by causing the screwing block 22 to protrude from the long hole 12 while the metal fitting 1 is attached to the lower surface of the table top 6. The head 32 of the leg-side metal fitting 3 is in a state of being attached to the table leg 7, can be inserted into the receiving hole 21, and comes into contact with the tip of the mounting screw 4 screwed into the screw hole 23. An inclined pressure receiving surface 35 is formed, the mounting screw 4 is screwed into the screw hole 23, and the pressure receiving surface 35 is pressed by the tip of the mounting screw 4 so that the holding portion 11 is held between the holding metal fitting 2 and the flange 31 of the leg side metal fitting 3. Like to do.
An upper surface 11 a of the holding part 11 facing the holding metal 2 is a tapered surface inclined along the longitudinal direction of the long hole 12 with respect to the horizontal upper and lower surfaces of the flange 10 of the receiving metal 1. It is characterized by that.

  In the present invention, the clamping metal fitting 2 is pressed against the upper surface 11a of the receiving metal fitting 1 by the coupling of the mounting screw 4, but is inclined according to the taper angle, and finally is inclined according to the taper angle. Since it is in close contact with the sandwiching upper surface 11a in a state, the sandwiching force is higher than that in the case of being horizontal, and displacement due to external force and displacement due to rotation in the left-right direction are prevented.

  In the above configuration, the upper surface 11a of the clamping part 11 facing the clamping metal fitting 2 is arranged along the longitudinal direction of the long hole 12 with respect to the horizontal upper and lower surfaces of the flange part 10 of the receiving metal fitting 1. The taper surface is inclined downward from the threaded portion of the screw 4, and the lower surface 11 b of the clamping portion 11 is parallel to the horizontal upper and lower surfaces of the flange portion 10 of the metal fitting 1. . It is desirable that the inclination angle of the tapered surface be approximately 3 degrees.

  Further, on the lower surface of the flange portion 10 (the upper surface in FIGS. 2 and 3), a pair of isosceles triangular marks 14 indicating the mounting direction of the holding metal fitting 2 are projected by convex markings, and the top portion is cut. It is directed toward the notch 13 side. Further, as shown in FIG. 1, the upper surface 11a (lower surface in the figure) of the holding part 11 of the metal fitting 1 is a fine uneven roughened surface such as emboss, and gradually increases in thickness toward the notch 13 side. The taper surface that increases

  An upper surface 11a of the clamping part 11 forming the tapered surface facing the clamping metal fitting 2 extends along the longitudinal direction of the long hole 12 with respect to the horizontal upper and lower surfaces of the flange part 10 of the receiving metal fitting 1. The lower surface 11b of the clamping portion 11 is parallel to the horizontal upper and lower surfaces of the flange portion 10 of the metal fitting 1. The inclination angle α of the tapered surface is approximately 3 degrees as shown in FIG.

  The holding metal fitting 2 has a substantially short columnar shape with notches 20 formed on part of both sides of the upper surface (lower surface in FIGS. 2 and 3), and rough machining of the lower surface 2b (upper surface in FIGS. 2 and 3). In addition to the surface as a clamping part, a receiving hole 21 penetrating in the vertical direction is formed in the center part. At one end in the longitudinal direction of the receiving hole 21, a screwing block 22 inserted into the long hole 12 is projected, and the front inclined surface center of the screwing block 22 communicates with the receiving hole 21. A screw hole 23 for screwing the mounting screw 4 is formed.

  Further, on the lower surface 2b (the upper surface in FIGS. 2 and 3) of the holding metal fitting 2, a roughened surface is formed by fine uneven processing such as embossing. Further, an alignment mark 24 indicating the same directivity as the alignment mark 14 is provided on the top portion (lower surface) of the screwing block 22 by projecting marks.

  The leg-side metal fitting 3 is provided with a substantially columnar mounting shaft 30 inserted through the center of the end of the table leg 7, and projects integrally from the end of the mounting shaft 30 via a flange 31. And a screw receiving block 32 serving as a head inserted into the two receiving holes 21.

  A male screw portion 33 is formed on the outer periphery of the mounting shaft 30 and both sides thereof are cut, and penetrates a pair of pin holes 34 through which the pin 5 is inserted perpendicularly to the upper and lower sides in the axial direction. Forming. The male thread portion 33 functions not as a screw for the leg 7 but as an unevenness for the extraction resistance.

  The flange 31 is used for inserting and positioning the mounting shaft 30 and fixing the mounting shaft 30 with respect to the leg 7. The notches 31a for inserting countersunk screws to be described later are formed on both sides of the flange 31.

  The screw receiving block 32 is fitted into the receiving hole 21 of the clamping plate 2 through the long hole 12 of the receiving metal fitting 1 and forms an inclined pressure receiving surface 35 on which the tip of the mounting screw 4 abuts. Thus, the clamping portion 11 of the receiving metal fitting 1 is firmly clamped between the flange 31 of the leg-side metal fitting 3 and the surface of the clamping metal fitting 2 by screwing the mounting screw 4. In addition, the lower surface 2b of the clamping metal fitting 2 and the upper surface 11a of the clamping part 11 of the receiving metal fitting 1 are firmly connected to each other by a meshing effect of the roughened surface.

  Next, the table top and leg connection structure and the connection procedure using the above fixture will be described with reference to FIG. In FIG. 3, two steps of mounting holes 60 and 61 are formed concentrically at the four corners of the bottom surface of the wooden top plate 6 by processing of a router or the like.

  The first-stage mounting hole 60 corresponds to the diameter and thickness of the receiving metal fitting 1, and the second-stage mounting hole 62 is slightly larger than the diameter and thickness of the holding metal fitting 2, so It is attached to be movable.

  In the above-described configuration, after the screwing block 22 of the sandwiching metal fitting 2 is inserted into the elongated hole 12 of the receiving metal fitting 1 in a loosely fitted state, the longitudinal direction of the elongated hole 12 is set to one side surface of the top plate 6. , And the notch 13 is fitted into the mounting hole 60 so that the side of the notch 13 is opposite to the corner of the top plate 6, and is fixed with a countersunk screw toward the screw lower hole 10 a formed in the mounting hole 60. By screwing the tool B, as shown in FIG. 4 and FIG. 5A, the holding metal fitting 1 is fixed to the corner of the top plate 6 on the same surface. Since this mounting direction can be easily confirmed by looking at the alignment marks 14 and 24, there is no mistake in operation.

  Further, as shown in an enlarged view in FIG. 6, the flange portion 10 of the metal fitting 1 in a fixed state is positioned slightly deeper than the surface of the mounting hole 60, that is, the bottom surface of the top plate 6, and the protruding surface of the alignment mark 14. Is in the same plane as the lower surface of the top plate 6 or slightly protruded from the top plate 6, and the holding metal fitting 2 remains loosely fitted so as to be movable back and forth and left and right.

  On the other hand, the wooden leg 7 fixed to the top plate 6 has a substantially square-shaped leg column shape, and is attached for insertion of the shaft portion 30 of the leg-side metal fitting 3 at the center of the top. A hole 70 is opened, and a pin insertion hole 71 that matches the pin hole 34 in the state where the front-rear shaft portion 30 is positioned and inserted is opened at the center of one side surface. A notch 72 for insertion of the mounting screw 4 having an inclined shape is formed in the center between them.

  Accordingly, when the shaft portion 30 is inserted into the mounting hole 70 and the fixing tool B made of a countersunk screw is screwed into the notch 31a on both sides of the flange 31 into the screw lower holes 70a formed at two locations around the mounting hole 70, 4. As shown in FIG. 5A, the fixing of the leg-side metal fitting 3 is completed with the flange 31 and the screw receiving block 32 protruding from the center of the top surface. Since the pin hole 34 and the insertion hole 71 coincide with each other in this state, the attachment shaft 30 is reinforced by the pin 5 if the pin 5 passes through the insertion hole 71 through the insertion hole 71. Although not shown, if the pin 5 is attached to the other pin hole 34 orthogonal to the pin hole 34 in the same manner, the attachment shaft 30 can be further reinforced.

  After each assembly, as shown in FIG. 5 (b), when the leg body 7 is stood on the receiving metal 1, the screw receiving block 32 protruding from the tip of the leg 7 becomes the receiving hole of the holding metal 2. 21 is inserted. After that, if the mounting screw 4 is inserted into the screw hole 23 of the clamping metal fitting 2 through the bolt insertion notch 72 and screwed using a hexagon wrench or the like, the tip of the mounting screw 4 becomes as shown in FIG. Then, abutting against the pressure receiving surface 35 of the screw receiving block 32, and further tightening the mounting screw 4 in this state, the screw receiving block 3 is pushed down, and the clamping metal fitting 2 is pushed up. The clamping part 11 of the receiving metal 1 is clamped between the flanges 31 of the metal fitting 3, whereby the fixing of the legs 7 to the top plate 6 is completed. Note that the upper surface 11a of the sandwiching portion 11 (the lower surface side in the figure has a tapered shape and is inclined at a predetermined angle α so that the thickness gradually increases toward the notch 13 as shown in FIG. As the mounting screw 4 is tightened, the holding metal fitting 2 is in close contact with the back surface of the holding portion 11 while the angle of the holding metal fitting 2 is inclined according to the inclination thereof.

  As a result, the coupling surface finally inclines, so that the coupling strength is higher than that of the horizontal coupling form, and the roughened surface is the lower surface 2b of the clamping metal fitting 2 and the upper surface 11a of the clamping part 11 of the metal fitting 1. Due to the frictional force, the clamping part 11 is firmly clamped between the clamping metal fitting 2 and the flange 31.

  Further, a part of the outer periphery of the male screw portion 40 of the mounting screw 4 is pre-coated with a high friction member 40a such as a thermoplastic resin as shown in an enlarged view in FIG. The friction member 40a is melted and filled between the screw pitches of the meshing portions to prevent the loosening, thereby preventing the loosening of the mounting screw 4 after the mounting.

  During the above-described mounting operation, there may be a case where the leg 7 is displaced in the rotational direction with respect to the top plate 6 as shown in FIG. These shifts are corrected sequentially in the tightening process of the mounting screw 4 to increase the tightening torque, and in the completely fixed state, as shown in FIG. Assembling is completed in a state in which both side surfaces and the corner ridge line portion are completely matched.

  In the assembled state, the mating mark 14 of the receiving metal fitting 1 and the mating mark 24 of the holding metal fitting 2 also assist the rotation prevention by biting into the top surface of the wooden leg 7 made of a softer material. As a result, assembly with high accuracy is prevented, and displacement after aging is prevented.

  Next, FIGS. 9 and 10 show another embodiment in assembly. In addition, since the structure of each member which comprises a fixture is the same as the said embodiment, it demonstrates using the same code | symbol for the same member. In each figure, the receiving metal fitting 1 and the holding metal fitting 2 are straight with respect to the corners of the top plate 6 so that the notches 13 are directed toward the side of the top plate 6, and are formed on both sides of the top plate 6. It is fixed to the mounting hole 60 at an angle of 45 °. The leg-side metal fitting 3 is also attached so that both longitudinal sides of the flange 31 are directed to the diagonal line position of the leg body 7, and an attachment hole 73 is formed in the inner ridge line portion of the leg body 7 accordingly. Moreover, the point which forms the notch 74 for the bolt insertion inclined on the upper ridgeline only differs from the said embodiment, and others are the same.

  The operational effects of this embodiment are the same as those of the above embodiment, but the mounting hole 73 bolt insertion notch 74 is formed on the side of the top plate 6, so that the formed portion is not visible from the outside. Therefore, the appearance is improved and there is an effect of preventing mischief.

  In the above embodiments, the present invention is applied to the mounting of a square leg having a square cross section. However, the present invention is not necessarily applied to a square cross section but a polygonal or rectangular cross section or a cylindrical leg. Of course, it is also possible.
