Description

  The present invention relates to a table, and is particularly suitable for a table that can be used independently or used by connecting a plurality of units.

  Most tables have a structure in which the top plate is supported by rod-like legs, and the shape in plan view is often rectangular. Then, when two tables are arranged side by side or back to back, adjacent top plates are connected with metal fittings. For example, two square tables in plan view that can be seated one by one on each side are connected to the left and right to form a rectangular table that three people can face each other. ing.

  In this way, when two tables are connected, there is a problem that the legs in the vicinity of the abutting portion in adjacent tables are likely to hit the user's foot. A leg positioned near one side (abutting side) constituting the contact portion is shifted to the back side of the table. For example, Patent Document 1 discloses that the leg device is shifted and moved to the inside of the table along the abutting side of the top plate in the plane view as it is, and is fixed with screws (bolts) in that state. Therefore, on the lower surface of the top plate, there are a group of screw holes for fixing the leg device to the outer position (first leg mounting portion), and a screw hole group for fixing the leg device to the inner position (second leg mounting portion). Is formed in advance.

  The leg device of Patent Document 1 has a structure in which a top plate support portion having a large area is provided on the upper end of a leg body that is long in the vertical direction. It is in a posture that protrudes from the center of the main body toward the diagonal direction of the top board. Therefore, in a state where the leg device is arranged at the outer position (first leg mounting portion), the top plate support portion having a large area can be firmly fixed to the top plate while the leg body is positioned as close to the outside of the top plate as possible. It can be said that the stability when the tables are used independently without being connected can be improved.

JP 2004-4204819 A

  Now, if the leg device is provided with a wide area top plate support part (bracket) as in Patent Document 1, the support strength is obtained when the leg device is arranged at the inner position (first leg attachment part) to connect the tables. In this aspect, it is preferable that the fixing position of the top plate support portion is as close to the outside of the top plate as possible. That is, when connecting the tables, the two front and rear leg devices are arranged along the abutting side of the top plate, but the support strength is to increase the distance between the top plate support portions of the front and rear leg devices as much as possible. It is preferable in terms of securing.

  However, in Patent Document 1, the leg device is merely shifted to the outer position and the inner position in the same posture, and in the state where the leg device is in the outer position, the top plate support portion is closer to the abutment side of the top plate than the leg body. Since the top plate support part is located on the inner side along the abutment side of the top plate than the leg body, the support strength surface is maintained. There was a risk that it would be hard to say.

  The present invention has been made to improve the current situation.

  The table of the present invention includes a top plate having a planar view and a plurality of leg devices that support the top plate, and the leg device is based on one outer side that is one side of the periphery of the top plate. Thus, an outer position close to the outer side and an inner position far from the outer side can be replaced. For this reason, a first screw for holding the leg device at the outer position is provided on the lower surface of the top plate. A basic configuration is such that a hole and a second screw hole for holding the leg device in the inner position are formed in advance.

  Furthermore, in the invention of claim 1, the leg device has a structure having a leg body that is long in the vertical direction and a bracket provided at the upper end thereof, and the center of the leg body and the center of the bracket are shifted from each other in plan view. In addition, the bracket has a mounting hole for screwing the screw into the screw hole of the top plate. Further, when the leg device is in the outer position, the outer side of the top plate is used as a reference. When the bracket is displaced inward from the leg body and the leg device is in the inward position, the bracket is set to be displaced outward from the leg body with reference to the outer side of the top plate. .

  According to a second aspect of the present invention, in the first aspect, when the leg device is at the outer position, a line connecting the center of the leg main body and the center of the bracket in a plan view is substantially the same as the diagonal direction of the top plate. The leg view posture of the leg device when it is in the inner position is a state in which the plan view posture of the leg device when it is at the outer position is horizontally turned by approximately 90 °.

  According to a third aspect of the present invention, in the first or second aspect, the top plate is a square in plan view, and four hollow square reinforcing frames extending in parallel with the sides of the top plate are fixed to the lower surface of the top plate. These four reinforcing frames are arranged in such a manner that the end surfaces of the two first reinforcing frames extending in parallel overlap the side surfaces of the other two second reinforcing frames from the outside.

  On the other hand, the bracket of the leg device has a square shape in plan view, and an engaging portion that can overlap with an end of the reinforcing frame is formed at a corner of the bracket located on the opposite side of the leg body. When the device is in the outer position, the bracket engaging portion of the leg device overlaps the end of the second reinforcing frame, and when the leg device is in the inner position, the bracket engaging portion of the leg device is The second reinforcing frame is set so as to overlap with the end of the first reinforcing frame, and the engaging portion of the bracket and the end of the first reinforcing frame or the second reinforcing frame are screwed. It is designed to be fastened to the top board.

  In the present invention, when the leg device is switched between the outer position and the inner position, the posture changes so that the bracket is positioned inside the leg column at the outer position and the bracket is positioned outside the leg column at the inner position. For this reason, if it is assumed that the leg struts are in the same position as Patent Document 1 at the inner position, the bracket is positioned on the outer side than in Patent Document 1, and thus the support strength of the top plate can be improved. (The support strength is high because the interval between the brackets arranged forward and backward along the contact side can be increased.)

If the structure of Claim 2 is employ | adopted, it can prevent a bracket from protruding to the outer side of a top plate, and can make a leg main body as close to the outer end of the corner of a top plate as possible, making a bracket as wide an area as possible. Therefore, it is possible to place the bracket on the corner end of the leg body while increasing the fixing strength of the bracket, and further contribute to improving the support strength of the top plate when the leg device is in the outer position (when the table is used independently). it can. In addition, even if the leg device is horizontally rotated by about 90 ° from the posture when it is in the outer position, the bracket is not exposed to the outer side of the top plate. Therefore, the leg device is arranged at the inner position (the table is connected). Will not be disturbed.

  If the structure of Claim 3 is employ | adopted, in addition to the top plate being reinforced by the reinforcement frame, the bracket and the reinforcement frame of the leg device both when the leg device is in the outer position and when it is in the inner position Since the engaging portion is fastened together with the top plate, the unity of the top plate, the reinforcing frame, and the leg device is improved, and the strength can be further improved.

  Next, an embodiment of the present invention will be described with reference to the drawings. First, a first embodiment shown in FIGS. 1 to 8 will be described. The table 1 includes a top plate 2 that is a quadrangle (square) in plan view and four leg devices 3 that support the top plate 2 at the four corners, and can be used alone as shown by a solid line in FIG. As shown in FIG. 1 by adding a one-dot difference line, the sides can be connected in contact with each other.

  When the table 1 is used alone, for example, one person can sit on the outside of the four circumferences. Therefore, there is no difference between the front and rear and the left and right of the table 1, but for convenience, based on the connected state, Of the four circumferences of the top plate 2, the sides that contact each other are referred to as contact sides and are denoted by reference numeral 2a, and the two sides orthogonal to the contact side 2a are referred to as outer sides and denoted by reference numeral 2b. When the table 1 is connected to three or more stations, the table located in the middle has two contact sides 2a.

(1) Leg device First, the leg device 3 will be described. For example, as shown in FIGS. 5 and 7, the leg device 3 includes a leg body (leg support) 4 that is long in the vertical direction and a bracket 5 fixed to the upper end thereof. The leg main body 4 is a metal hollow product such as an aluminum extruded product, and one corner portion is a cut chamfered portion 6. Further, as clearly shown in FIG. 7 (C), longitudinal grooves 7 opened in the axial direction are formed in three corner portions excluding the chamfered portion 6 in the inner peripheral portion of the leg body 4. Screws can be screwed into the longitudinal grooves 7. The longitudinal groove 7 is basically circular and opens toward the inside of the leg body 4.

The bracket 5 is a metal or resin molded product such as an aluminum die-cast product or a zinc die-cast product, and has a leg portion 8 that fits tightly inside the leg body 4 and a rectangular shape in plan view that overlaps the lower surface of the top plate 1. The support portion 9 protrudes in the direction of the chamfered portion 6 (diagonal direction of the leg main body 4) across the axis of the leg main body 4. Accordingly, as shown in FIG. 3A, the center O1 of the leg body 4 and the center O2 of the support portion 9 are shifted from each other in plan view, and a line O3 connecting both the centers O1 and O2 is It extends in a diagonal direction (more precisely, a direction inclined by 45 ° from the outer side 2b and the contact side 2a in plan view). Alternatively, it can be paraphrased that the line O3 intersects with each surface of the leg body 4 at an angle of 45 ° in plan view.

  As shown in FIG. 7A, a flange portion 10 is provided at the upper end of the foot portion 8 of the bracket 5 so as to overlap the upper end surface of the leg main body 4, and this flange portion 10 is attached to the leg main body 4 with the leg fastening screws 11. It is fixed. That is, the bracket 5 is fixed to the leg main body 4 by screwing the leg fastening screw 11 into the vertical groove 7 of the leg main body 4. A set screw 12 is screwed into the foot 8 from the upper end of the chamfered portion 6 of the leg body 4. For this reason, the foot 8 is firmly fixed to the leg body 4.

  A notch 13 is formed in a portion of the upper portion of the leg body 4 centering on the chamfered portion 6, while a step portion 14 that fits into the notch 13 is formed in the foot portion 8 of the bracket 5. The arm portion 15 extends in a diagonal direction of the leg body 4 in a state of being continuous with the step portion 14 and the flange portion 10. And the support part 9 is integrally provided in the arm part 15 (it can also be expressed that the arm part 15 is provided in the support part 9 and the arm part 15 is continued to the foot part 8). .

  The flange portion 10 is stepped down from the base end of the arm portion 15, but the upper end of the flange portion 10 can be flush with the upper surface of the arm portion 15 (or the support portion 9). A number of recesses 16 are formed on the upper surface of the support portion 9.

  A corner portion of the support portion 9 opposite to the leg body 4 is an engaging portion 17 stepped down in a square shape in plan view, and a boss portion 18 having a circular shape in plan view faces upward on a bottom plate constituting the engaging portion 17. The boss 18 is provided with a mounting hole 19 penetrating vertically. The engaging portion 17 is square in plan view, and the boss portion 18 is located at the center of the square. A mounting hole 19 penetrating vertically is also formed in the other corner portion of the support portion 9. Therefore, the interval dimension W1 of the four mounting holes 19 is the same.

  As shown in FIG. 4A, a receiving plate 20 is fixed to the lower end surface of the leg body 4 with screws, and an adjuster bolt 21 is attached to the receiving plate 20. Further, for example, as shown in FIG. 4B, a protruding portion 22 is provided at each corner portion sandwiching the chamfered portion 6 among the four corner portions of the leg body 4, and the protruding portion 22 has a chamfered portion 6. A dovetail groove 23 opened in the direction is provided. A wiring duct 24 and a decorative cover (not shown) can be attached to the dovetail 23.

(2). Mounting structure of the leg device to the top plate The top plate 2 of the present embodiment is a wood system. Therefore, in order to increase the load bearing capacity, as shown in FIG. Reinforcing frames 26 and 27 extending along each side are fixed. The reinforcing frames 26 and 27 use square steel pipes having a quadrangular cross section (square), two first reinforcing frames 26 extending in parallel with the outer side 2 b of the top plate 2, and the contact side 2 a of the top plate 2. It is comprised by the 2nd 2nd reinforcement frame 27 extended in parallel. As representatively shown in FIG. 3 (B), a plurality of reinforcing frames 26 and 27 are fixed to the top plate 2 with frame screws (bolts) 28, and screws 28 are screwed into the top plate 2. The demon nut 29 is buried.

  As shown in FIGS. 2 and 3A, the second reinforcing frame 27 is disposed such that one side surface thereof abuts against the end surface of the first reinforcing frame 26, and both end portions of the second reinforcing frame 27. Protrudes outside the front and rear sides of the first reinforcing frame 26.

  When the table 1 is used alone, the leg device 3 is arranged at the outer position of the corner portion of the top plate 2 as shown in FIG. 2, for example. As shown in FIG. 8, it is arranged at the inner position that extends from the outer side 2 b along the contact side 2 a of the top plate 2, but when the leg device 3 is at the outer side, the engaging portion of the bracket 5 17 is fitted to the end portion of the second reinforcing frame 17 from below, and the engaging portion 17 and the second reinforcing frame 27 are fastened to the top plate 2 with a fastening screw 30.

  Needless to say, the fastening screw 30 is inserted into the mounting hole 19 of the bracket 5 from below. Further, on the lower surface of the top plate 2, a group of four first screw holes 32 for fixing the bracket 5 at the outer position and a group of four second screw holes 33 for fixing the bracket 5 at the inner position. Are formed in advance. As shown in FIG. 6, both screw holes 32 and 33 are constituted by demon nuts 29.

  When the table 1 is connected and used, the leg device 3 is arranged at the inner position. In this case, the leg device 4 is positioned so that the leg body 4 is located inside the bracket 5 with respect to the outer side 2b. The device 3 is rotated 90 ° horizontally with respect to the posture in the case of the outer position. And when arrange | positioning the leg apparatus 3 in an inner side position, remove from the 2nd reinforcement frame 27 and the top plate 2, and engage the engaging part 17 of the bracket 5 with the edge part of the 1st reinforcement frame 26 from the downward direction, The engaging portion 17 of the bracket 5 and the end portion of the first reinforcing frame 26 are fastened together with the top plate 3 with fastening screws 30. A fitting hole 31 into which the boss portion 18 of the bracket 5 is fitted vertically penetrates the end portions of both the reinforcing frames 26 and 27.

  As shown in FIG. 3C, U-shaped movable clamps 34 in a plan view are arranged at both ends of the first reinforcing frame 26. A long hole 35 extending in the longitudinal direction of the first reinforcing frame 26 is formed in both side plates 34 a of the movable clamp 34, and a horizontal stopper pin 36 inserted through the first reinforcing frame 26 is fitted in the long hole 35. The stopper pin 36 is located on the opposite side of the second reinforcing frame 27 with the fitting hole 31 interposed therebetween.

  The movable clamp 34 can slide with the stroke of the elongated hole 35, but when the movable clamp 34 is completely moved in the direction toward the outside of the first reinforcing frame 26, the both side plates 34 a are connected and the base portion is on the side surface of the second reinforcing frame 27. The base portion is set so as to be positioned on the pin 35 side with respect to the fitting hole 31 when it approaches and moves outward. The base of the movable clamp 34 is provided with a burring portion 37 in which a female thread is cut. The bolt 38 inserted through the second reinforcement frame 27 is screwed into the burring portion, whereby the second reinforcement frame 27 is attached to the first reinforcement frame. 27 is firmly fixed.

  As a means for connecting the tables 1 to each other, as shown in FIG. 8, for example, a connecting plate 39 made of a metal plate is arranged so as to straddle the two top plates 2, and these are attached to both the top plates with screws 40. Fix to 2. It is also possible to use the first screw holes 32 for connecting the top plate 2, and in this case, as shown by a two-dot chain line in FIG. 8, the four first screw holes 32 are fully used. It is also possible to fasten the connecting plate 39 ′ or fasten the connecting plate 39 ″ using the first screw holes 32 one by one (or two by one).

  Since the second reinforcing frame 27 is not used when the leg device 3 is in the inner position, the second reinforcing frame 27 can be used as a connecting member between the top plates. Of course, other connecting means (connecting member) can also be employed. Further, as shown in FIG. 8, when the leg device 3 is in the inner position, the second reinforcing frame 27 can be placed on the outer side of the first reinforcing frame 26. It can be easily realized to change from to independent specification.

As shown in FIG. 1, a square-shaped wiring hole 45 is formed in the center of the top plate 2, and a cable receiver 46 is fixed to the lower surface of the top plate 2. The cable receiver 46 has a box shape with an upward opening, and a wiring passage 47 is formed at each corner.

(3) Summary of Embodiment As described above, when the table 1 is used independently as a single unit, the leg device 1 is arranged at an outer position close to the corner of the top plate 2 so that high support stability is achieved. Can be secured. In particular, when the leg body 4 and the bracket 5 are formed in a square shape in plan view as in the embodiment, the leg body 4 can be brought to the corner of the top board 2 while the bracket 5 is hidden on the lower surface of the top board 2. Therefore, higher support stability can be ensured.

  As the support span of the leg body 4 increases, the bending moment acting on the top plate 2 also increases. However, if the reinforcing frames 26 and 27 are provided as in this embodiment, the rigidity of the top plate 2 is improved and high strength is ensured. It is an advantage that can be done. Further, the bracket 5 of the leg device 3 may be simply fastened to the top plate 2 at either the outer position or the inner position. However, when the ends of the reinforcing frames 26 and 27 are tightened together at both positions as in this embodiment, the bracket 5 5 and the reinforcement frames 26 and 27 are ensured to be more robust.

  The first reinforcing frame 26 has a function of reinforcing the top plate 2, but it is preferable to bring the first reinforcing frame 26 as close as possible to the outer side 2 b of the top plate 2 in terms of securing the reinforcing function. On the other hand, the leg device 3 is shifted to the inner position so as not to obstruct the user's foot. Therefore, in the state where the leg device 3 is disposed at the inner position, the leg body 4 is attached to the top plate 2. It is preferable that it is located inside the outer side 2b as much as possible while ensuring stability.

  If the bracket 5 is fixed to the first reinforcing frame 26 in a state where the leg device 3 is merely shifted from the outer position along the contact side 2a without changing its posture, the leg body 4 is attached to the first reinforcing frame 26. Since it is located on the near side (side closer to the outer side 2b), there arises a problem that the leg body 4 is likely to hit the user's foot. That is, the function of improving the reinforcing function of the top plate 2 by bringing the first reinforcing frame 26 to the outside, and the leg main body 4 positioned as far as possible (back side) when the table 1 is connected to obstruct the human foot. There is a conflict with the function that prevents it from happening.

  On the other hand, in this embodiment, when the leg device 3 is disposed at the inner position, the leg main body 4 is positioned on the inner side of the bracket 5, so that the leg main body 4 is moved as far as possible without moving the first reinforcing frame 26 too far. As a result, it is possible to achieve both the reinforcing function of the top plate 2 and the function of preventing the user from hitting the foot. This is one of the advantages of this embodiment.

  Further, as shown in FIG. 3A, the fitting hole 31 of the first reinforcing frame 26 is located on the opposite side of the contact side 2a from the fitting hole 31 of the second reinforcing frame 27. Therefore, when the leg device 3 is disposed at the inner position, the leg main body 4 is opposite to the abutting side 2a by the width dimension of the second reinforcing frame 27 than when it is at the outer position. Therefore, the distance dimension W2 between the leg bodies 4 in the adjacent tables 1 is larger than the distance dimension when the leg device 3 is arranged at the outer position. For this reason, the bending span strength of the top plate 2 can be improved by reducing the support span in the direction of the outer side 2b.

(4). Second Embodiment FIG. 9 shows a second embodiment which is a modification of the bracket 5 and the reinforcing frames 26 and 27. This embodiment is different from the first embodiment only in the engaging portion 27 of the bracket 5, and the other configuration is the same as that of the first embodiment.

That is, in this embodiment, the engaging portion of the bracket 5 has a configuration in which the intermediate plate 42 is provided at the intermediate height position, and the boss portions 43 protrude from the upper and lower sides of the intermediate plate 42. , 27 is formed with a slit 44 that fits into the intermediate plate 42. The boss portion 43 enters the reinforcement frames 26 and 27. The upper and lower inner surfaces of the slit groove 44 and the intermediate plate 42 may be in contact with each other or may not be in contact with each other.

  In the embodiment of (A), the slit groove 44 is formed in each of the two side plates of the reinforcing frames 26 and 27. However, in the example shown in (B), only one side plate of the reinforcing frames 26 and 27 is provided. A notch groove 44 is formed. Therefore, in the example of (B), the intermediate plate 42 is stepped down from the outer surface of the support portion 9 by the thickness of the reinforcing frames 26 and 27 in plan view. In any case, in the embodiment of FIG. 9, it can be said that the boss portion 43 is sandwiched between the upper and lower plates of the reinforcing frames 26 and 27, and thus is excellent in strength.

(5). Others The present invention can be embodied in various ways other than the above embodiment. For example, the top plate need not be square, but may be rectangular. When the top plate is rectangular, two connection modes can be selected: a mode in which the short sides are brought into contact with each other and a mode in which the long sides are brought into contact with each other.

  The specific shape and structure of the leg device can also be set arbitrarily. For example, the bracket and the leg main body can be integrated, and conversely, one or both of the leg main body and the bracket can be formed of a plurality of members. It is also possible to set the leg body to a circle and the bracket 5 to a square such as a square.

  The “square top plate” described in the claims means to have a plurality of corner portions, and therefore includes a semicircular shape and a U shape. A quadrangular table generally has four leg devices, but only two of them can be used as the inner / outer position changing type, and the other two positions can be fixed. In the case of a rectangular table having a long length, it is also possible to provide an intermediate leg whose position is fixed. As the hollow rectangular reinforcing frame, channel steel having a C-shaped cross section can also be used.

  The present invention can be embodied in a table. Therefore, it can be used industrially.
