Description

  The present invention relates to a table supported by legs having rod-like columns, and is characterized by a structure that allows a plurality of units to be connected to the left and right.

  In a table in which a top plate having a rectangular shape in plan view is supported by rod-like legs, connecting a plurality of units to the left and right is widely performed. And in a square table, legs are often arranged at the four corners of the top plate, but if the tables are simply arranged side by side on the left and right, a person can sit on the chair outside the abutment portion between the top plates. When it is used and seated, the leg of the abutting part gets in the way of a person's foot, and the table cannot be used in a state where the chair is pulled, so that there is a problem that usability is poor.

  Therefore, Patent Document 1 is provided with a first leg mounting portion for fixing the legs with the legs arranged on the outer side and a second leg mounting section for fixing the legs with the legs arranged on the inner side. In addition, by connecting the leg to the second leg mounting portion at the time of connection, the table can be used in a state where the chair is pulled when a chair is placed on the contact portion of the connected table and a person sits down. Is disclosed.

  In addition, in Patent Document 2 as another known example, in connecting two left and right tables, legs are arranged in a state of straddling two left and right top boards, and one leg is made into two top boards. A configuration that is fixed is disclosed. Accordingly, in Patent Document 2, the legs are also used as connecting members between the top plates.

JP 2004-57345 A Japanese Utility Model Sho 62-20524 microfilm

  In Patent Document 1, the legs only change their positions along the side surfaces of the top board, and the legs of each table are hidden under the top boards in a connected state. Therefore, the left and right top plates are connected only by the connecting metal fittings, and the connecting metal fittings are arranged at the front portion and the rear portion of the top plate. However, in this connection mode, if the legs attached to the second leg attaching portions of the left and right top plates are not accurately adjusted, there is a problem that a step is generated between the left and right top plates and the appearance is likely to be deteriorated.

  Also, if the table is placed on a carpet stretched on the floor, even if the left and right top plates are aligned, if a heavy article is placed on one top plate, the legs of the table on which the device is placed There is also concern that a slight difference will occur between the left and right top plates. Regarding this point, it can be said that a connecting member is also arranged on the inner side of the top plate, and the top plate may be connected to the front and rear end portions and the inside, but this increases the number of connecting members, so the labor of member management is increased. Problems such as an increase occur.

  In this regard, in the configuration of Patent Document 2, since the legs are arranged across the left and right top plates, the left and right top plates are always aligned in height, and a heavy article is placed on one table. There is no step between the top plates. In addition, since the legs are also used as connecting members, an increase in the number of connecting members can be prevented.

  Now, since the side edge of each top plate is supported by two legs, if the left and right top plates are connected and the two legs are shifted inward, the leg posts as in Patent Document 2 are used. In the configuration where is positioned directly below the abutting portions of the left and right top plates, the leg columns are arranged in a line along the abutment line of the top plate. Then, the leg struts are concentrated on the narrow part of the floor and the stability may be deteriorated. In the case of a leg provided with a support on the bracket, as shown in Patent Document 1, the axis of the support and the center of the bracket are often shifted. There is a possibility that it becomes troublesome to arrange the columns in a row at the position of the mating surface between the top plates.

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

The table of the present invention is
A top plate having a straight side surface in plan view, and a plurality of legs that support the top plate;
Each of the legs has a bracket that overlaps the lower surface of the top plate, and a column that is suspended from the bracket.
The legs can be replaced with an outer position and an inner position separated from each other along the side surface of the top plate. When the legs are arranged at the inner position, the two top plates are placed side by side so that the side surfaces overlap each other. When connected, the basic structure is such that a person can sit on the outside of the contact portion between the left and right top plates to use the top plate.

And in invention of Claim 1, in the said basic composition,
The legs are arranged so that they are all hidden by the top plate in a plan view at the outer position, and at the inner position, the column is hidden under the top plate and a part of the bracket is exposed outside the side surface of the top plate. Has been placed,
The two top plates with the legs arranged at the inner position are arranged such that the left and right top plates are connected by bolts at the brackets of each leg in a state where the side surfaces overlap each other and are arranged side by side. .

The invention of claim 2 is the invention according to claim 1,
An end frame extending in parallel with the side surface is disposed in a portion near the side surface of the lower surface of the top plate,
With the two top plates having the legs arranged in the inner position, the side surfaces of the top plates are arranged side by side so that the side surfaces of the top plates are arranged side by side. And the fitting part formed in these flanges and an end frame is fitting.

The invention of claim 3 is the invention of claim 2,
While the fitting portion of the bracket is a square engagement protrusion, the fitting portion of the end frame is a square engagement hole, and the engagement protrusion and the support column are in a state where the legs are arranged at the inner position. The front plate is displaced in the front-rear direction, which is the longitudinal direction of the side surface.

The invention of claim 4 is the invention according to claim 3,
The flange has a rectangular base in plan view, the pillar is provided at one corner in the base,
In the state where the leg is disposed at the outer position, the support column is positioned at a corner portion of the top plate in a posture in which one side of the base portion of the bracket is parallel to the side surface of the top plate, and the bracket While the protrusion provided in the corner portion located in the diagonal direction of the support column of the base portion of the base portion is fitted into the end portion of the end frame,
In a state in which the legs are arranged at the inner position, the legs are arranged in a posture in which the protrusion is turned outward by horizontally turning 90 degrees from the posture of the outer position, and the engagement is arranged on the tip surface of the protrusion. A protrusion is provided.

Invention of Claim 5 in any one of Claims 1-4,
In the end frame, a plurality of upward pedestal portions that overlap the lower surface of the top plate are formed so as to jump in the longitudinal direction, and therefore, the location of the pedestal portion is provided between the top plate and the end frame. Except for the gaps,
In the top plate connection state in which the legs are arranged at the inner position, the front and rear end portions of the left and right top plates are reverse L-shaped left and right long connection fittings having an upper horizontal portion that fits between the end frame and the top plate. While being connected by
In the non-connected state in which the legs are arranged at the outer position, the connecting metal fitting is in the longitudinal and longitudinal posture, with the upper horizontal portion fitted into the gap between the end frame and the top plate, Arranged on the side.

  In the first aspect of the invention, the left and right top plates are aligned at the inner position, but are connected using legs, so the left and right top plates can be connected without increasing the number of connecting fittings. It can be maintained in the same plane. And since the support of the leg is located below each top plate and only the bracket is arranged across the left and right top plates, the center of the bracket and the axis of the support are displaced. It can be easily applied to types of legs. Therefore, it is excellent in versatility.

  Moreover, since the support | pillar is each arrange | positioned under the left-right top plate, compared with the case where a support | pillar is arrange | positioned in a line, the group of support | pillars can be supported with a wider area of a floor. For this reason, it can also contribute to the improvement of the stability of the table.

  Now, in a connectable type table, it is common to provide a female screw hole (usually a demon nut) in advance on the lower surface of the top plate and screw the bolt inserted through the bracket into the female screw hole on the top plate. When the bracket is straddling the left and right top plates as in the invention, the bolts are screwed into the left and right top plates, respectively. Therefore, the bracket needs to be accurately positioned so that the bolt insertion holes coincide with the female screw holes of the left and right top plates.

  In this regard, if the configuration of claim 2 is adopted, each bracket (each leg) is positioned by the end frame of the mating table, so that there is an advantage that the assembly can be performed accurately. Moreover, since the end frame also serves as a reinforcing member for preventing the top plate from being bent, the rigidity of the entire table can be improved.

  Various combinations are possible for the fitting part of the bracket and the end frame. However, if the engagement hole is provided in the end frame having the engagement protrusion on the bracket as in claim 3, the structure can be easily processed with a simple structure. become. In other words, tie-cast products and resin-molded products are usually used for the brackets, so that the engagement projections are formed without trouble by molding, while the end frame is usually made of a metal mold. The engagement hole can be easily machined.

  In the connected state, it is possible to position the support column and the engagement protrusion at the same position in the front-rear direction (line up left and right), but the bracket area is usually larger than the flat area of the support column (Otherwise, the bracket cannot be firmly fixed to the top plate.) If the support column and the engaging projection are aligned in a straight line in the connected state, it may be difficult to close the gap between the adjacent legs in the front and rear direction.

  On the other hand, as in claim 3, when the support column and the engaging protrusion are shifted in the front-rear direction at the inner position, the brackets of the front and rear legs mesh with each other in a connected state while ensuring a sufficient size for the bracket. Since it can be in such a state, the freedom of design can be increased.

  If the structure of Claim 4 is employ | adopted, in the state which has arrange | positioned the leg in the outer side position, since the protrusion part of a bracket is inserted in the edge part of an end frame, while being able to position a leg correctly also in an outer side position, The rigidity of the table can be improved by integrating the bracket.

  In the present invention, the left and right top plates can be connected using the legs. However, since the legs are located on the inner side, the left and right top plates are also connected to the outer side portions (front and rear end portions) with connecting metal fittings. preferable. The connection fitting used in this case is not necessary when the table is used in a non-connected state (when the table is used alone), and is therefore stored somewhere when not in use.

  In this respect, in the present invention, since the connecting bracket can be stored using the gap between the end frame and the top plate, it can be excellent in quick response so that it can be immediately taken out in a connected state, There is no problem of loss. The gap between the end frame and the top plate can also be used as a cable insertion space.

(1). Outline of Table Next, an embodiment of the present invention will be described with reference to the drawings. In the present application, front / rear / left / right wording is used to specify the direction, but the arrangement direction of the connected tables is defined as the left / right direction, and the direction orthogonal thereto is defined as the front / rear direction.

  In the case of the rectangular table shown in FIGS. 1 to 9, since the short side surfaces are brought into contact with each other and connected, the longitudinal direction (frontage direction) is the left-right direction and the short side (width direction) is the front-rear direction. As a precaution, the direction is clearly shown in FIG. In the case of a square table as shown in FIG. 10, since how to connect is not constant, the direction of any two parallel sides is the left-right direction, and the direction orthogonal thereto is the front-rear direction.

  As described above, the table shown in FIGS. 1 to 9 has a rectangular specification, and includes a top plate 1 that is rectangular in plan view and four legs 2 that support the table. The leg 2 can be replaced with two positions, an outer position located at the corner portion of the top board 1 and an inner position located inside along the one side surface of the top board 1, and the leg 2 at the place where they overlap each other. Tables can be connected to each other by placing the at the inner position.

  The top plate 1 is made of wood. For example, as shown in FIG. 1B, the bottom surface of the top plate 1 has a longitudinally long end frame 3 disposed near the short side and a left and right end frame 3. The end frame 3 is fixed with bolts 5 shown in (see FIG. 3B) (both the end frame 3 and the reinforcing bar 4). May be fixed to the top board 1).

  The reinforcing bar 4 and the end frame 3 may be fixed by welding or may be fixed by bolts. In the case of fixing with bolts, for example, a rectangular boss body that fits into the end of the reinforcing bar 4 is protruded laterally on the end frame 3, and a bolt inserted through the reinforcing bar 4 from below is screwed into the reinforcing bar 4. In this case, the reinforcing bar 4 and the end frame 3 can be firmly fixed.

  The reinforcing bar 4, the end frame 3, and the legs 2 constitute a table frame. The top plate 1 is made of wood, but is made of steel, or a laminated product in which metal plates (steel plates) are bonded to the upper and lower surfaces of a lightweight core member made of paper or the like. It is also possible.

  In two places on the left and right sides of the portion along the center line of the top plate 1, square-shaped wiring holes 6 in plan view are vacant. As shown in the example of FIG. 10, a center panel 7 can be erected on the front and rear intermediate portion of the top plate 1. The center panel 7 is attached using a rod attached to the wiring hole 6.

(2). Leg Structure As shown in FIG. 4, for example, the leg 2 includes a bracket 8 fixed to the lower surface of the top plate 1 and a column 9 attached to the bracket 8. The bracket 8 is a die-cast product made of aluminum, for example (may be a resin molded product), and has a base portion 8a having a square shape in plan view.

  Then, a square support post 10 having a square shape in plan view is integrally provided at one corner of the base 8a, and a rectangular tubular support 9 is fitted from below onto a square downward boss 11 provided on the support attachment 10. It is crowded. One diagonal line of the column mounting part 10 and one diagonal line of the base part 8 a overlap each other, and one virtual corner on the outer periphery of the base part 8 a is the center of the column mounting part 10. Therefore, the column attaching portion 10 is partially protruded from the base portion 8a.

  The downward boss 11 has a box-like shape opened upward, and a bolt receiving seat 12 (see FIG. 4A) is provided inside, and the bolt receiving seat 12 has two bolts opened up and down. An insertion hole 13 is formed. On the other hand, a square nut plate 14 is fixed to the upper portion of the inside of the column 9 by welding, and the lower surface of the downward boss 11 overlaps the nut plate 14. Then, as shown in FIG. 4A, the column 9 is fixed to the bracket 8 by screwing the bolt 15 inserted through the bolt receiving seat 12 from above into the female screw hole 14 a of the nut plate 14.

  As clearly shown in FIG. 4 (B) C), the base portion 8a of the bracket 8 is formed with a downward spine portion 16 connected to the downward boss 11, thereby ensuring the strength as the bracket 8. A large load can be supported even if the support column 9 is provided eccentrically. Since the spine portion 16 is connected to the downward boss 11, a notch 17 that avoids interference with the spine portion 16 is formed in the upper portion of the support column 9. The spine portion 16 has a groove shape opened upward, and a reinforcing rib 18 is formed along the center line. Further, both sides of the bracket 8 sandwiching the spine portion 16 are in a flange state.

  Of the base portion 8a of the bracket 8, a substantially square protrusion 19 that fits into the end frame 3 from the outside is integrally formed at a corner portion on the opposite side of the column mounting portion 10 across the center. Since the protrusion 19 is oriented in the same direction as the end frame 3, it is directed not in the diagonal direction of the base 8a but in a direction perpendicular to one side constituting the base 8a.

  The top plate 1 is supported by four legs 2, but the front and rear legs 2 have the positional relationship between the support 9 and the bracket 8 reversed so that the leg 2 has the projection 19 in plan view. Two types differing by 90 degrees are used. Further, as shown in FIG. 4, for example, the protrusion 19 has a two-stage type of a first portion 19a connected to the base portion 8a and a second portion 19b protruding from the first portion 19a. 19 b fits into the end frame 3. Accordingly, the second portion 19b is slightly smaller (by the thickness of the end frame 3) than the first portion.

  There is a slight level difference between the first portion 19a and the base portion 8a. Therefore, a slight (several mm) gap is provided between the end frame 3 and the top plate 1. In addition, in the bracket 8 shown to FIG. 7 (B) and FIG. 8 (A) (B), the 1st part 19a and the base 8a are the same height. Therefore, the form is slightly different from that shown in FIGS. Either may be sufficient.

  As shown in FIG. 4 (B), the protrusion 19 has an H-shape having an intermediate plate portion 20 with grooves formed on the upper surface and the lower surface, and penetrates the intermediate plate portion 19c vertically. The through-hole 20 is made. A bolt 21 is inserted into the end frame 3 and the protrusion 19 from below, and the bolt 21 is screwed into a female screw hole (demon nut) provided in the top plate 1 so that the end frame 3 and the protrusion 19 are connected to each other. It is fixed to the plate 1. As shown in FIGS. 4C, 5 </ b> B, and 5 </ b> C, a land portion 22 that overlaps the intermediate plate portion 19 c of the protrusion 19 is formed at the end of the lower surface portion of the end frame 3.

(3) Fastening structure between bracket and top plate For example, as shown in FIG. 4, the bracket 8 has bolt insertion holes 23 to 26. That is, the bracket 8 has a first bolt insertion hole 23 used for fixing to the top plate 1 at both the outer position and the inner position, and the top plate 1 with the legs 2 arranged at the outer position. The second bolt insertion hole 24 used for fixing and the third and fourth bolt insertion holes 25, 26 used for fixing to the top plate 1 when the leg 2 is disposed at the inner position open vertically. And then vacated. A countersink hole into which the head of the bolt fits is formed in the lower part of each bolt insertion hole 23-26.

  The first bolt insertion hole 23 is formed at a substantially central portion of the base portion 8a. On the other hand, the second bolt insertion hole 24 has a total of three corner portions, one corner portion approaching the protrusion 19 at a position on the center line of the spine portion 16 and two corner portions sandwiching the center line of the spine portion 16. It is formed in places. Therefore, at the outer position, the bracket 8 of the leg 2 is fixed to the top plate 1 with the four bolts 27 (see FIG. 4A). Along with this, four internal thread holes (demon nuts) are provided in each corner portion of the top plate 1, and this is an outer position leg fixing portion.

  The third bolt insertion hole 25 and the fourth bolt insertion hole 25 are provided inside two sides of the base portion 8a located on the protruding portion 19 side. One of the third bolt insertion hole 25 and the fourth bolt insertion hole 26 is used. Since the third bolt insertion hole 25 and the fourth bolt insertion hole 26 are formed in one bracket 8, two types of four legs 2 are sufficient.

  For example, as shown in FIGS. 3 (B) and 4 (C), a plurality of pedestal-shaped upward pedestal portions 28 are formed on the upper surface of the end frame 3 so as to bulge out. It is fixed to the top plate 1 with bolts 5. Therefore, a gap having the same dimension as the protruding height of the pedestal 28 is provided between the top plate 1 and the end frame 3. Even if a plate material (spacer) is fixed to the upper surface of the end frame 3 by welding or the like, a gap can be formed between the end frame 3 and the top plate 1.

  As shown in FIGS. 5B and 5C, a large hole 30 is formed in the lower portion of each pedestal portion 28 in the end frame 3, and a resin cylinder 31 opened vertically in the hole 30. Wearing. Therefore, the bolt 5 does not enter the end frame 3 in the fixing work to the top plate 1.

In other words, if the cylindrical body 31 is not provided, when the pedestal portion 28 is fixed to the top plate 1 with the bolt 5, the bolt 5 may fall into the end frame 3 accidentally, making it impossible to take out. When the cylindrical body 31 is mounted, the bolt 5 can be reliably prevented from falling into the end frame 3. The cylindrical body 31 is adapted to be fitted into the hole 30 against its elasticity, and after being fitted, the cylinder 31 is returned and deformed, and the claw is caught on the edge of the hole 30 and is held so as not to fall off. You may form the washer part which the seat surface of the volt | bolt 5 overlaps at the upper end of the cylinder 31. FIG.

(4). Table connection In FIG. 6 and FIGS. 8A and 8C, a state in which the tables are connected to the left and right is displayed. When connecting the tables, the legs 2 positioned at the positions of the one side surface 1a and the other side surface 1b with which the top plates 1 abut are shifted to the inner position. At the inner position, the leg 2 is in a posture in which the protrusion 19 faces the opponent's table. Accordingly, the posture of the leg 2 differs by 90 degrees in plan view between the outer position and the inner position.

  For convenience, the lower side of the drawing will be described as the front and the upper side as the rear. For the sake of convenience, in the right top plate 1, the leg 2 that is disposed in the front at the outer position is counterclockwise from the outer position. The leg 2 which is horizontally rotated 90 degrees around and located behind the inner position and located rearward at the outer position is horizontally rotated 90 degrees clockwise from the attitude of the outer position to the inner position. In both cases, the column mounting portion 10 is brought close to the side surface of the end frame 3 of the right top plate 1, and the protrusion 19 is located on the side surface of the end frame 3 on the left top plate 1. It is made to contact.

  On the other hand, in the top plate 1 positioned on the left in FIG. 6, the leg 2 that is disposed at the front in the outer position is horizontally rotated 90 degrees clockwise from the outer position, and is disposed on the front side of the inner position. The leg 2 located rearward at the outer position is horizontally rotated 90 degrees counterclockwise from the posture of the outer position, and is disposed on the rear side at the inner position. Is brought close to the side surface of the end frame 3 of the left top plate 1, and the tip of the protrusion 19 is in contact with the side surface of the end frame 3 of the right top plate 1.

  Then, as shown in FIG. 7B, a square engagement protrusion 32 is formed at the tip of the protrusion 19 of each leg 2 as a fitting part of the leg 2 at the center, while the end frame. 3 includes an engagement hole 33 in which the engagement protrusion 32 is non-rotatably fitted as a fitting portion of the end frame 3, and each bracket 8 is connected to the end frame 3 by fitting the both. Positioning has been performed.

  The projecting portion 19 of the bracket 8 has a horizontal female screw hole 34 at the center thereof, and a horizontal bolt 35 (see FIG. 8A) inserted through the end frame 3 is screwed into the female screw hole 34. Thus, the end frame 3 and the bracket 8 are fixed.

  In a state where the legs 2 are arranged at the inner position, each bracket 8 is fixed to the left and right top plates 1 with bolts 5. However, since the column mounting portions 10 and the protrusions 19 are arranged side by side, the left and right top plates 1 are arranged. Is fixed using the first bolt insertion hole 23 and the third bolt insertion hole 25. When the left and right top plates 1 are fixed with the bolts 5 one by one, the fourth bolt insertion hole 26 and one second bolt insertion hole 24 can be used. In this case, the top plate 1 is provided with a female screw hole corresponding to the fourth bolt insertion hole 26 and one second bolt insertion hole 24. Therefore, the fourth bolt insertion hole 26 is a preliminary one. One bracket 8 can be fixed with four bolts 5.

  As can be understood from FIG. 6, in each leg 2, the engagement protrusion 32 and the column 9 are displaced in the front-rear direction at the inner position (both are displaced in the left-right direction at the outer position). By forming the base portion 8a of the bracket 8 in a square shape and shifting the engagement protrusion 32 and the support column 9 in the front-rear direction, the pair of legs 2 overlapped in the front-rear direction can be brought closer to each other. For this reason, the struts 9 of the pair of legs 2 can be arranged side by side in a straight line. As a result, the stability of the table can be improved.

  In addition, in the connection position of tables, the two legs 2 are set, and there is some space between the front and rear sets, but this is to ensure the support stability of the top board 1. It is. In any case, since there is a considerable space between the leg 2 and the front and rear edges of the top board 1, when a person places a chair at the connecting portion and sits down normally, the leg is leg 2 It will not hit the column 9. Therefore, it is easy to use.

  In addition, since there is a large gap between the front and rear of the group of legs 2, a wagon can be arranged. In this case, the wagon may be entirely hidden under the top plate 1 or may partially protrude outside the top plate 1. Whether the whole is hidden or part of it depends on the depth of the wagon.

  For example, as clearly shown in FIG. 8, the front plate 1 arranged side by side is connected to the front portion and the rear portion by a connection fitting 36. The connecting metal fitting 36 has an inverted L shape having an upper horizontal portion 36a and a vertical portion, and a cover 37 is attached from the outside. The cover 37 is fixed to the connection fitting 36 with screws. The upper horizontal portion 36a of the connecting bracket 36 is inserted into the gap between the end portion of the end frame 3 and the top plate 1, and the end portion of the connecting bracket 36 and the end frame 3 are fixed to the top plate 1 by the bolts 21. ing. For fixing the end portion of the coupling metal 36, the bolt 21 used for fixing the protruding portion 19 of the bracket 8 at the outer position is used as it is.

  The connecting metal fitting 36 is not used in a non-connected state. Therefore, in the present embodiment, the connection fitting 36 is stored in a portion of the lower surface portion of the top plate 1 along the outer surface of the end frame 3 when not in use. That is, as shown in FIGS. 7A and 8B, the upper horizontal portion 36 a of the coupling metal 36 is inserted into the gap between the top plate 1 and the end frame 3 at the front and rear intermediate positions of the end frame 3. Thus, the connecting fitting 36 is stored in the short side edge of the top plate 1.

  Since the end frame 3 is disposed at a position close to the side surfaces 1a and 1b of the top plate 1, there is a possibility that the connection fitting 36 may come into contact with human eyes, but since the connection fitting 36 is provided with a cover 37, Touching does not worsen the aesthetics. The connecting metal fitting 36 may be fixed to the side surface of the end frame 3 with screws or the like, or an edge piece 37 a provided on the cover 37 is elastically stretched between the end frame 3 and the top plate 1. It may be held in a state that does not easily fall off. The connecting fitting 35 is disposed between two pedestals 28 adjacent to each other in the front-rear direction. Therefore, even if it is not screwed, it does not slip out in the front-rear direction.

  The embodiment of the present invention has been described above, but the present invention can be embodied in various ways. For example, the left and right end faces of the front and rear reinforcing bars may be opened outward and the protrusions formed on the bracket may be fitted to the reinforcing bars. Therefore, in this case, the protrusion is directed in the left-right direction at the outer position. The legs do not necessarily have to be rotated 90 degrees horizontally between the outer position and the inner position, but can be simply moved back and forth and replaced.

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