DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for outdoor activities that can be easily and firmly assembled by fitting members together, and can be easily disassembled and transported by children and women. Related to the assembly table.

[0002]

2. Description of the Related Art Today, with the development of motorization, groups, such as families, often go out to outdoor activities such as auto camping, driving, fishing, and the like. In order to carry out such group outdoor activities, it is common to bring a folding table or a table / chair set in which a folding chair is incorporated into a folding table.

In this folding table, the top plate and each leg are connected to each other with pins, bolts, or hinges so that the legs can be folded on the lower surface of the top plate, and the legs are fixed in an expanded state. In order to do so, a folding brace is attached to the top plate and each leg.

[0004] The folding table and chair set is
Furthermore, the seat plate is connected to each leg or top plate of the folding table with pins, bolts, or hinges so that the seat plate can be folded above or below the legs folded on the lower surface of the top plate, and expanded. In order to support the seat plate horizontally on the legs, a folding brace is mounted on the seat plate and each leg or the top plate.

[0005]

In such a conventional foldable furniture, the members of the table or the chairs added to the table are connected to each other so that they can be integrally carried, so that they are apparently convenient to carry. It looks like, but carrying all the parts of the table and chairs at the same time would inevitably make heavy and weak people, such as children and women, unable to load or unload them from the car. There is a problem that it is not possible to carry to a camp site 10 m away.

[0006] As a result, the folding furniture cannot be carried in outdoor activities such as camping only by women or women and children alone, and the promotion of outdoor activities is limited. Also, for children and women who cannot participate in the installation or removal of foldable furniture, for example, the sense of unity that the whole family participates and camps is weakened, and in some cases, the sense of alienation is felt and the sense of unity is deepened. Camps may be undermined.

Further, when a folding table or a table / chair set in which a folding chair is incorporated in a folding table is transported by an automobile, the stability is poor due to the folded legs and chairs. As a result of rubbing the difference, there is also a problem that the table and the bed are scratched.

[0008] Further, if the brace or the leg accidentally hits the body or another object during use, the brace is folded, the top plate is tilted unexpectedly, and the object placed on the top plate scatters around.
May slide down. As a result, heated foods fall on the surrounding people, which may cause burns or scalds, especially when the lamp falls and causes a fire, or when the stove is put on the top plate and tempura is performed. In such a case, if such a tilt of the top plate occurs, the fire of the stove is transferred to the heated tempura oil, and there is a risk of causing a fire.

In view of the above circumstances, the present invention can be easily assembled by fitting each member together, and can be assembled so robustly as to prevent the top plate from tilting, and can be easily disassembled. It is an object of the present invention to provide an assembly table that can be carried by children and women.

[0010]

A first assembly table of the present invention (hereinafter referred to as the first invention) has at least two upright leg plate members in order to achieve the above object. It comprises a base and a top plate placed on the base,
Each of the leg plate members is formed with a groove that is recessed downward from an upper edge thereof and / or upward from a lower edge thereof and has a groove width equal to or substantially the same as the thickness of the other leg plate members, Each of the leg plate members is inserted into a groove of another leg plate member so that the leg plate members can be assembled so as to cross each other in plan view, and one of the upper surface of at least one leg plate member and the lower surface of the top plate A projection is formed on the other side, and a projection is formed on the other side, and the top plate is positioned on the base by fitting the projection with the projection. It is characterized by.

[0011] Thus, the base can be easily assembled by inserting the leg plate members into the recesses formed on the other side, and can be easily disassembled by extracting from the recesses on the other side. That is, it is easy and easy to disassemble and assemble by inserting and removing parts called leg plate materials, so that children and women can disassemble and assemble, and can be disassembled into parts and easily carried by children and women. .

In addition, since the leg plate members are inserted into the recesses of the other leg plate members to prevent their movement and inclination in the plate thickness direction, they are securely assembled, and the leg plate members are erroneously inserted into the leg plate members during use. There is no danger that the pedestal will suddenly collapse even if hit by an object or another object, and therefore, there is no danger of the top plate suddenly tilting.

After the base is assembled, the top is placed on the base, and the projections and the recesses are fitted to each other to fit the projections and the recesses by their own weights. Can be positioned and supported on the base, and
It can be disassembled simply by lifting the top plate from the base. That is, it is easy to assemble and disassemble the top plate, and it is possible to assemble and disassemble with a simple operation, so that children and women can disassemble and assemble, and the top plate can be disassembled and easily carried by children and women.

Hereinafter, the first invention will be described in detail. The pedestal portion of the first invention has at least two leg plate members arranged so as to intersect each other in a plan view, and each leg plate member has a lower portion from its upper edge and / or an upper portion from its lower edge. And a groove having the same or substantially the same groove width as the thickness of the other leg plate material is formed.

For example, when the pedestal portion is constituted by two leg plate members, a groove is formed to be recessed upward from the lower edge of one leg plate member, and is recessed downward from the upper edge of the other leg plate member. A groove is formed. Since these groove widths are formed to be the same or substantially the same as the thicknesses of the other leg plate members, they can be inserted and combined into the grooves of the other leg plate members.

The crossing angle between the two leg plate members is not particularly limited, but is preferably 2 in plan view to simplify the groove processing.
It is preferable to combine the leg plate members so as to be orthogonal to each other.

Further, in this case, each leg plate may intersect with another leg plate at any position in the plate width direction. It is preferable to cross the plate.

Further, for example, when the pedestal portion is constituted by three leg plate members, the three leg plate members are assembled so as to intersect at one point. A groove for inserting the second leg plate material is recessed upward from the edge, and a groove for inserting the first leg plate material is recessed downward from the upper edge of the second leg plate material, and a third groove is formed from the lower edge thereof. A groove for inserting the leg plate is formed, and a groove for inserting the first and second leg plate is recessed from the upper edge of the third leg plate. Then, for example, a third leg plate is set up, and the second leg plate is inserted into the groove from above, and the third leg plate is inserted into the lower groove of the second leg plate. Inserting the first leg plate into the upper groove of the second leg plate and the groove of the third leg plate, and inserting the second and third leg plate into the groove of the first leg plate in order. As a result, the leg plate members are assembled so that they intersect at a single point in a plan view, for example, at an intersection angle of 120 °.

As an example of using four or more leg plate members, two leg plate members which are orthogonal to each other in plan view are used as one set, and two or more leg plate members are used at an appropriate interval, or four leg plate members are used in plan view. Assembled so as to intersect at one point.

It goes without saying that the leg plate members can be formed as independent members, but two or more leg plate members may be connected in a single plate to form a continuous leg plate member.

When such a continuous leg plate is provided, the number of parts can be reduced, and the workability of assembly can be improved.

For example, in the case of a double leg plate in which two leg plate members are connected in a single plate shape, grooves for inserting other leg plate members are formed at both ends. These grooves may be recessed at one end from the top and recessed at the other end from the bottom,
In order to reduce the number of types of shapes of the other leg plate members that intersect with the two-leg plate member, it is preferable that the grooves at both ends are recessed from either the upper side or the lower side.

In the case where the two leg plate members are provided, two leg plate members are connected by one double leg plate member or at least one leg plate member is disposed between a pair of leg plate members arranged in parallel. The leg plate members are arranged in parallel with these leg plate members, and these leg plate members and the two leg plate members are sequentially connected with other leg plate members, or three or more double leg plate members are sequentially arranged in a polygonal annular shape in plan view. A pedestal portion combined to intersect can be configured.

When a pedestal portion is formed so as to sequentially intersect in a polygonal annular shape in plan view, when an odd number of two-legged plate members is used, the groove at one end of each of the two-legged plate members is One type of two-legged plate that is recessed from the lower edge and the other end is recessed from the upper edge is used. When an even number of two-legged plate is used, each two-legged plate is used. The groove at one end of the leg plate may be recessed from the lower edge, and the groove at the other end may be a single-legged double-legged plate recessed from the upper edge, or both grooves may be recessed from the lower edge. Alternatively, two types of double-legged plate materials may be used, one having a recessed upper edge.

In the case where a groove having the same or substantially the same groove width as the thickness of the two double leg plate members is formed in another leg plate member intersecting the two leg plate members, one leg plate member may be used. 1 having grooves having the same or substantially the same groove width as the plate thickness and being arranged in parallel with each other.
At least one leg plate having a groove having the same or substantially the same groove width as the thickness of the two two-leg plate members is disposed between the pair of leg plate members, and these leg plate members are sequentially connected by the two-leg plate members. You can assemble it.

In the case of a multiple leg plate having three or more leg plate members formed in a single plate shape, three or more strips into which another leg plate material or a continuous leg plate material is inserted at an appropriate interval in the connection direction. Are formed. These grooves are also preferably recessed from either the upper side or the lower side in order to reduce the number of types of shapes of the other leg plate members intersecting the multiple leg plate members.

In the case of the three or more multiple leg members, three or more other leg members or multiple leg members arranged in parallel with each other in a plan view are combined as if skewered by the multiple leg members. In addition to the multi-span pedestal portion, it is possible to assemble a polygonal annular pedestal portion in plan view similarly to the double leg plate material.

The material of the leg plate material or the continuous leg plate material is not particularly limited. For example, a light metal such as aluminum, wood, synthetic resin, corrugated cardboard, or a composite material such as decorative plywood may be used.

In the first aspect of the present invention, the leg plate members or the leg plate member and the continuous leg plate member are assembled by being inserted into grooves formed on the other side, and can be disassembled by extracting from the other groove. That is, for example, by holding the leg plate material on the ground and holding it with one hand, and inserting another leg plate material into the leg plate material, or one person holding the leg plate material on the ground and another person inserting another leg plate material This makes it possible to easily assemble the leg plate members, and when disassembling, the reverse is only necessary. Therefore, when assembling the pedestal, only one leg plate or continuous leg plate is lifted by one person, and even a child or a woman can lightly lift and assemble or disassemble. It can be transported up to 10m away.

Since the leg plate and the continuous leg plate material are inserted into the other groove, displacement and inclination in the plate thickness direction are prevented by the other plate. Therefore, the leg plate and the continuous leg plate are erroneously assembled during use. There is no danger that the base will suddenly collapse even if people or objects hit the leg plate or continuous leg plate, so that the top plate will not suddenly tilt, such as food on the top plate, hot boiled food, high temperature As a result, it is possible to prevent the tempura oil and the like from scattering around, and to prevent the lighted stove or lamp from falling, thereby significantly improving the safety.

In the first aspect of the present invention, a beam may be provided instead of or together with the continuous leg plate, and in this case, the beam and the leg plate may be provided from an upper edge thereof downward and / or a lower edge thereof. A groove having the same or substantially the same groove width as the thickness of the other leg plate material or the width of the beam material is formed, and the beam material and each leg plate are mutually connected to the groove of the other leg plate material or the beam material. By inserting, the beam member and each leg plate are assembled so as to intersect in plan view.

Here, the beam material is different from the continuous leg plate material in that the lower edge thereof does not contact the ground, but at least two adjacent leg plate materials (or continuous leg plate materials) like the continuous leg plate material.
May be connected to each other by fitting them. Therefore, even if the shape of the beam is vertical,
Although it may be shaft-shaped, it is recommended to use an upright plate-shaped one so that it can be stably and firmly combined with the leg plate material with a relatively small cross-sectional area.

In the first aspect of the present invention, of course, the assembled leg plate members or the leg plate member and the beam member are further fixed to each other by bolts and nuts via metal fittings, for example.
You may make it possible to assemble the leg plate material and the beam material more robustly.

In the first invention, the top plate may be a single plate including a plywood or a plurality of divided plates. In the case of a divided top plate, the divided The respective parts may or may not be connected to each other by a hinge or the like.

The material of the top plate is not particularly limited, and examples thereof include light alloys such as aluminum, wood, synthetic resins, cardboard paper and decorative plywood. Of course, you can print or paint a suitable decorative pattern on the top of this top plate,
Further, an edge frame made of, for example, an extruded aluminum material or a synthetic resin may be provided at the peripheral edge.

The top shape of the top plate may be a curved shape such as a circle, an ellipse, or a gourd, or a bent line such as a triangle, square, rectangle, pentagon, hexagon, octagon, or star. An arbitrary shape such as a shape having the outline of the above or a shape obtained by combining these shapes can be selected.

Further, even if the thickness of the top plate is uniform,
It may not be uniform, for example, the peripheral portion and the central portion can be thickened to increase the strength of the peripheral portion and the central portion, and further, a concave portion for inserting a lower portion of tableware such as a cup at an appropriate position Or a through-hole, or a through-hole into which a flagpole, a parasol post, or the like is inserted can also be formed.

In the first aspect of the present invention, the top plate is placed on the assembled base portion, and the projection and the recess are fitted by their own weight by fitting the projection provided on one side with the recess provided on the other side. Then, the base and the top plate are assembled. In addition, the base and the top plate can be disassembled simply by lifting the top plate from the base.

It is optional whether the projection is provided on either the base or the top plate, and it is also possible to provide the projection and the concave portion in correspondence with both the base and the top plate. However, it is advantageous to form a recess in the lower surface of the top plate in order to disassemble and reduce the height when each member is laid down and stacked, so that the projection is provided on the upper surface of the base. Is recommended.

When a projection is formed on the pedestal, a leg plate material,
Protrusions may be formed on at least one of the continuous leg plate material and the beam material, and the number of the protrusions may be one or two or more.

When one projection is provided on a leg plate, a continuous leg plate, a beam, or the like, it may be provided at a position eccentric from the center in the plate width direction. It is preferably provided in a portion, and is preferably formed in a non-circular column shape including a polygon such as an ellipse, a rectangle, or a square in order to prevent rotation of the top plate.

When two projections are provided on the leg plate material, the continuous leg plate material, the beam material, or the like, they may be provided close to the center in the plate width direction. It is preferable to provide at both ends.

The constituent members may be pulled out from a leg plate material, a continuous leg plate material, a beam material, or the like, or may be removed by screwing.

As a method of providing the projection on the top plate, a method of forming the projection by thinning a portion except for the projection on the lower surface of the top plate, or a method in which a projection separately formed on the top plate is nailed, Examples thereof include a method of fixing by screwing, bonding or a combination of two or more of them, and a method of implanting a projection on a top plate. In the method of implanting the projections on the top plate, the members constituting the projections may be pulled out from the top plate or may be screwed out.

The number of projections provided on the top plate is not particularly limited as long as it is one or more. However, in the case where two or more projections are provided for one leg plate material or continuous leg plate material or one beam material,
This is advantageous because the leg plate, the continuous leg plate material, the beam material, and the like can be prevented from horizontally rotating around the intersection.

The shape of the projection is not particularly limited. For example, the projection can be formed in an arbitrary shape such as a cylinder, a lunar column, a prism, or the like. In particular, in the case of forming a prismatic shape, particularly a rectangular prism such as a rectangle, a square, a rhombus, a trapezoid, or the like, a part of the upper end of a leg plate, a continuous leg plate, a beam, etc. It is more advantageous that the plate can be easily formed by cutting or cutting a part of the lower surface of the plate as a paragraph.

The recess may be formed in such a shape that the top plate can be positioned with respect to the pedestal portion by fitting with the projection, and it is not always necessary to form the recess in the same shape as the projection. It can be formed in a groove shape having the same groove width as the plate thickness of the beam or the diameter of the projection. Further, even if the recess is formed so as to penetrate from the lower surface of the top plate to the upper surface, it is formed so as not to penetrate the upper surface of the top plate. May not appear.

In the first invention, for example, a metal fitting having a screw hole is embedded or assembled on the upper surface of the pedestal.
A bolt inserted from above the top plate is screwed into the screw hole of this metal fitting, or a metal fitting having a bolt insertion hole is supported on the pedestal.A nut is inserted into the bolt inserted into the top plate and the bolt inserted into this metal fitting. By screwing, the top plate may be reliably prevented from being disassembled upward during use.

As described above, according to the first aspect of the present invention, parts such as the leg plate material, the continuous leg plate material, the beam material, and the top plate can be easily and easily assembled and disassembled even by children and women. Yes, and they can be carried lightly one at a time. Therefore, for example, even children and women carry parts from cars to campsites from cars alone,

In the present invention, the intersection where at least two selected from the leg plate, the continuous leg plate or the beam intersects is recessed below the lower surface of the top plate, and the intersection above the intersection is formed. A through-hole can be formed in the top plate, and in this case, a shaft-like object such as a flagpole or parasol handle is inserted into the intersection from this through-hole to support the shaft-like object. become able to. In addition, a hollow column inserted from above is provided at an intersection where at least two selected from a leg plate material, a continuous leg plate material or a beam material intersect, and a through hole through which the hollow column is inserted is formed in the top plate. Alternatively, the handle of the flagpole or parasol may be supported more reliably.

The first invention can be widely applied to an assembly table having a structure in which a top plate is supported by a base, such as a table and a chair, and can also be applied to a table / chair set combining a table and a chair. .

That is, in the first invention, a horizontal seating surface is formed on one or both side edges of at least one leg plate member, and a seat plate mounted on the seating surface is provided. Can be.

In this case, one of the seat receiving surface and the lower surface of the seat plate is provided with a projection projecting in the other direction, and the other side is formed with a concave portion into which the projection is fitted.
It is advantageous that the seat plate is positioned on the seat receiving surface by fitting the projection and the concave portion, so that the stability of the seat plate is enhanced.

In the first aspect of the present invention, in the case where the leg plate member is provided with a seat receiving surface and a seat plate to be mounted thereon is provided,
Provide a seat plate orthogonal to each seat surface in a plan view, and form a groove on the leg plate material that is the same or substantially the same as the thickness of the seat plate downward from the seat surface and shallower than the height of the seat plate. The seat plate is recessed and has a width equal to or approximately the same as the thickness of the leg plate material from the lower edge of the seat plate upward, with a depth obtained by subtracting the groove depth of the seat surface from the height of the seat plate. A groove is recessed, and the leg plate material and the seat plate are inserted into the other groove to assemble them so that the seat surface and the upper surface of the seat plate are flush or almost flush, and the seat surface and When the seat plate is placed on the upper surface of the seat plate, it is advantageous because the seat plate is stably supported.

In the first aspect of the invention, one of the seat receiving surface and the lower surface of the seat plate is provided with a projection protruding toward the other side, and the other side is formed with a concave portion into which the projection is fitted. The seat plate is configured to be positioned on the seat receiving surface by fitting of the seat plate and the concave portion, or a projection is provided on one of the upper surface of the seat receiving plate and the lower surface of the seat plate to project in the other direction. The other side is formed with a recess into which the projection is fitted, and the projection is fitted to the recess so that the seat plate is positioned on the seat receiving surface. It may be configured to be placed over a plurality of seat surfaces adjacent to each other in order.

Further, when a plurality of seat surfaces are provided, the seat plates may be provided independently of each other for each seat surface, but the seat plates must be placed sequentially over a plurality of adjacent seat surfaces. Thereby, the stability of the seat plate can be further enhanced. When the seat plate is placed over a plurality of seat surfaces adjacent to each other in this manner, the number of parts can be reduced by omitting the seat plate.

Of course, if the leg plate is provided with a seat receiving surface and a seat plate to be placed on the seat plate is provided, for example, a metal fitting having a screw hole is embedded in the seat receiving surface and is inserted from above the seat plate. Screw the bolt into the screw hole of this bracket,
The leg plate material and the seat support plate support the metal fitting with the bolt insertion hole, and the nut is screwed into the seat plate and the bolt inserted into this metal fitting, so that the seat plate is reliably prevented from being disassembled upward. You may make it. In this case, it is possible to omit the protrusions and recesses, but in order to simplify the alignment between the bolt insertion holes formed in the seat plate and the screw holes in the seat receiving surface, the protrusions and recesses are required. It is advantageous to provide.

Next, in order to achieve the above object, a second assembly table of the present invention (hereinafter referred to as the "second invention") has a column, radially arranged around the column, and an inner edge. At least three upright leg-like plate members having projections protruding from the column inserted into the column formed in the column over a predetermined height and having an inner edge in contact with the peripheral surface of the column at at least two upper and lower points; It is equipped with a base consisting of a restraint plate that restrains the leg plate at the position where it is inserted into the pillar, and a top plate placed on this base, and the top plate has one of the upper end portions of each leg plate material. The projection is formed with a concave portion on the other side, and the top plate is positioned on the base by fitting the protrusion and the concave portion.

Therefore,
Since it is sufficient to assemble the parts one by one, even children and women can easily and easily assemble. or,
Since the disassembly may be performed in the reverse order of the assembly, even a child or a woman can easily and easily disassemble. Each of the disassembled parts can be carried lightly by a child or a woman over, for example, several tens of meters.

In addition, since each leg plate member has its lower portion fitted to the column, displacement and inclination in the plate thickness direction are prevented, and
Since the upper end and the lower part are fitted to the positioning fitting portion and the restraint plate and positioned, there is no possibility that the column or the leg plate may be unexpectedly tilted even when a person or another object hits the leg plate or the column during use, for example.
Therefore, there is no danger of the top plate suddenly tilting.

Hereinafter, the second invention will be described in detail. The second invention is characterized in that a column is used for the base 1, and this column may be solid. However, the column is constituted by a hollow column, and a through hole or a hole through which the column is inserted into a top plate is provided. When a through-hole corresponding to the center hole of the pillar is formed, a shaft-like object such as a flagpole or a parasol handle can be inserted into the pillar from the through-hole of the top plate, and this shaft-like object can be supported upright. Become like

The outer shape of the column is not particularly limited, and it can be formed in any shape such as a cylinder or a prism. Even if the cross-sectional area is uniform between the upper and lower ends. , Top spreading taper, bottom spreading taper,
It may be changed arbitrarily such as a spindle shape. Of course, the surface of the pillar may be decorated by any method such as embossing, printing, painting, or attaching a decorative board.

The pillar is supported upright by at least three leg plate members arranged radially around the pillar. That is, the pillar is formed with a groove for inserting the inner edge of each leg plate material, and a protrusion protruding from the inner edge of the leg member is inserted into this groove, and each leg plate material is inserted into the lower part of the inner edge of the pillar. Since the restraint plate restrains the position inserted into the groove, the lower part of the pillar is reliably supported by each leg plate material.

The direction in which the projection of the inner edge of the leg plate is inserted into the pillar is not particularly limited, and the projection may be inserted in an upward direction, a downward direction, a centripetal direction, or a combined direction of the centripetal direction and the upward or downward direction. I just need. Among these, in consideration of the assembling workability, a projection in which the lower part of the inner edge is further projected in the column center direction is formed on the leg member, and a groove into which the projection can be inserted from below and from the centripetal direction is formed on the column. Preferably, it is formed.

The inner edge portion of each leg plate member is in contact with the peripheral surface of the pillar at at least two points at the position inserted into the groove of the pillar, whereby the pillar is supported upright.
