Abstract

PROBLEM TO BE SOLVED: To elongate the period of use, lower the environmental load at the time of discarding, and heighten the operation efficiency at the time of using by removably installing an upper face material on the top plate main body through an engagement part in the state of being positioned in the direction of the plane. SOLUTION: A top plate 1 is so constructed that a cutting mat 6 as an upper face material is removably installed on the top plate main body 4 through an engagement part AO in the state of being positioned in the direction of the plane. As the engagement part AO, a recessed part 45 is formed on the upper side of the top plate main body 4. The cutting mat 6 is an ordinary one made by a raw material which is hard to be easily broken by a cutter knife or the like and also permits the knife edge of the cutter knife to enter to a certain degree, for example, the mat has a three-layer structure of a soft layer, a hard layer and a soft layer. Thus, when the damage is serious or for the purpose of co-ordination in color lay-out, the cutting mat 6 can be easily replaced freely. At the time of discarding, the cutting mat 6 and the top plate main body 4 can be separately collected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furniture top plate that can be suitably used for work that tends to stain or break the periphery.

[0002]

2. Description of the Related Art Conventionally, top plates such as desks, tables, desks and the like used for various operations have conventionally been prepared by applying an upper surface material such as a melamine resin decorative plate to a steel plate structure using an adhesive or the like. It is manufactured by sticking.

[0003]

However, such a conventional top plate is not suitable for use in operations that tend to contaminate or damage its periphery due to the following reasons of cost, environmental load, and work efficiency. It was appropriate.

[0004] In the conventional top plate, since the top member is fixed to the top plate structure, the top plate structure and the top member cannot be separated. For this reason, even if there is no problem in structural strength, if the top plate surface is contaminated or damaged, the entire product must be discarded, and at the time of disposal, it cannot be incorporated into the recycling cycle by separate collection. When the upper surface material is made of a non-recyclable or difficult material such as melamine resin, the environmental load at the time of disposal is further increased.

In consideration of such circumstances, operations that tend to stain or damage the periphery, such as operations using a sharp tool such as a cutter knife, writing with an oil-based pen, and various other types of work are conventionally performed. When performing on a top plate, a separate mat, cardboard, or the like is generally used to prevent the surface of the top plate from being worn, stained, or damaged. However, separate mats and cardboards do not always cover a sufficient work area and have problems such as slipping during the work, and the work efficiency is limited to a low level, and the effect of preventing contamination and damage is not sufficient.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem at once, that is, to provide a top plate having a long usable period, a low environmental load at the time of disposal, and a high working efficiency at the time of use. And

[0007]

In order to achieve the above object, the top plate of the present invention has a structure in which the upper surface member is positioned on the top plate main body. In addition to the above structure, the work can be performed comfortably directly on the upper surface material, and only the upper surface material can be replaced when the upper surface material is soiled or damaged by the work.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is a top plate for furniture,
The top plate is detachably attached to the main body of the top plate in a state of being positioned in the plane direction via the engaging portion.

A specific structure of the engaging portion may be a recess provided inside the peripheral portion of the upper portion of the top plate body.

In a preferred embodiment in this case, the thickness of the upper surface member is set larger than the depth of the recess.

As another structure of the engaging portion, the top plate body and the upper surface member may be engaged with each other by screws.

As another specific configuration of the engaging portion, a convex portion provided on one of the top plate body or the upper surface member,
A configuration including a corresponding concave portion corresponding to this convex portion provided on the other side is possible.

Such a configuration is particularly useful when the upper surface material is a cutting mat or a recyclable material.

[0014]

【Example】

<First Embodiment> Hereinafter, a furniture top plate 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3, and a modification will be described with reference to FIG.

FIG. 1 shows a table 2 to which a top plate 1 of the present invention is applied. The table 2 has a top plate main body 4 as a component of the top plate 1 fixed to the upper ends of four pillars 3, and an article mounting surface is formed below the top plate main body 4. A shelf plate 5 is provided between the pillars 3 for reinforcement.

The top plate 1 is characterized in that a cutting mat 6, which is an upper surface material, is detachably mounted on the top plate body 4 in a state where the cutting mat 6 is positioned in a plane direction via an engaging portion A0. In the top plate 1 of the present embodiment, as the engaging portion A0, the concave portion 4 is provided on the upper portion of the top plate main body 4 and inside the peripheral edge portion.
5 are provided.

As shown in FIG. 2, the top plate body 4 has backers 42 and 43 attached to the upper and lower surfaces of a frame member 41 and edge members 44 attached to four sides. At this time, the upper surface of the edge member 44 is set so as to protrude by a predetermined dimension d1 from the upper surface of the upper backer 42, and the upper surface of the top plate body 4 excluding the peripheral portion 4a is
2 and a rectangular recess 45 surrounded by the inner surface of the edge member 44. That is, the dimension d1 corresponds to the depth of the recess 45.

Then, another one of the top plate 1 is
A cutting mat 6 is detachably mounted as an upper surface material which is one of the components. The cutting mat 6 is a normal one made of a material that is not easily crushed by the cutter knife C shown in FIG. 3 or the like and that can accept the cutting edge of the cutter knife C to some extent. As an example, one having a three-layer structure of a soft layer-hard layer-soft layer can be mentioned. Then, the planar shape is made to substantially correspond to the planar shape of the concave portion 45, and the thickness dimension d
2 is, for example, several mm
It is set to be about ten and several mm larger.

With such a configuration, the recess 45 of the top plate body 4 removably positions the cutting mat 6, thereby eliminating the problems of cost, environmental load, and work efficiency of the conventional product. Is done.

First, since the cutting mat 6 can be attached to and detached from the concave portion 45, problems on cost and environmental load can be solved. That is, only the old or damaged cutting mat 6 is replaced to replace the top plate body 4.
By continuing to use, the surface is not contaminated or damaged, which does not lead to the disposal of the entire top plate 1. Further, the cutting mat 6 can be easily replaced at any time to unify the color layout with the surrounding furniture, and one top plate can be used by selectively using a plurality of types of cutting mats 6 according to the type of work. It also creates positive benefits, such as being able to handle many types of work in one. In addition, the cutting mat 6 and the top plate main body 4 can be separately collected at the time of disposal, and the burden on the environment can be reduced. If the cutting mat 6 is made of a recyclable material, both the cutting mat 6 and the top plate body 4 can be recycled, and the burden on the environment can be further reduced.

In particular, as shown in FIG. 3, since the thickness d2 of the cutting mat 6 is set to be larger than the depth d1 of the concave portion 45, the cutting operation is performed near the peripheral edge 4a of the top plate body 4. When performing the above, even if the blade of the cutter knife C reaches the peripheral portion 4a of the top plate body 4 or exceeds the peripheral portion 4a with excessive force,
Since the edge member 44 constituting the peripheral portion 4a of the top plate body 4 is located at a position lower than the cut surface, the edge member 44 is immediately
Will not lead to damage. For this reason, early deterioration of the top plate 4 can be effectively prevented. When a part of the cutting mat 6 projects above the edge member 44 of the top plate main body 4, the cutting mat 6 can be removed from the concave portion 44 without the top plate 4 being inverted by using the projected portion as a finger. It can be easily taken out. For this reason, workability at the time of replacing the cutting mat can be effectively improved.

Next, with regard to the working efficiency, there is an effect that the displacement is properly prohibited and a wide working area is covered.

Conventionally, when an object to be cut is placed on a tabletop such as a desk or a specific table and a cutting operation is performed using a cutter knife or the like, the sharp edge of the cutter knife causes the object to be cut. Use a commercially available cutting mat made of a material that protects the top plate and can accept the cutting edge of the cutter knife to a certain extent so that it does not penetrate and damage the top plate surface. A thick paper or the like having no paper is searched for, and is laid under the object to be cut to perform the above operation.

However, when using such a cutting mat, cardboard or the like, the cutting mat must be fixed by hand so as not to move together with the object to be cut, and the cutting operation must be performed while maintaining the state. Therefore, there is a problem that the work requires a lot of labor and the work itself becomes difficult. In particular, such an existing cutting mat or the like has a cutting area that is usually as small as an underlay, so that it is necessary to repeat the work little by little, making the above work more complicated. In addition, cutting mats, cardboard, etc. are easy to slide on the top plate, so they may slide sideways even if they are pressed and fixed by hand. In some cases, it was easy to do the work again.

However, in the top plate 1 of this embodiment, when the cutting mat 6 is mounted in the concave portion 45 of the top plate main body 4, the four sides of the cutting mat 6 are edge members forming the peripheral edge 4 a of the top plate main body 4. 44, the position is prevented from being shifted in the front, rear, left and right directions. For this reason, FIG.
As shown in (1), a person who performs the work of cutting the object to be cut X by using the cutter knife C only needs to fix the object to be cut X, and does not need to fix the cutting mat 6 at all. For this reason, the cutting operation can proceed with much less labor than the conventional method.

In particular, since the cutting mat 6 of the present embodiment can use a maximum of substantially the entire area of the top plate 1 as a cutting area, compared to the conventional method in which small-scale cutting operations are stacked in a narrow area, Can be performed more efficiently.

Further, since the cutting position does not become largely out of order due to the side slip of the cutting mat 6,
It is possible to effectively avoid being forced to redo work, and it is possible to effectively improve work efficiency.

In this way, a top plate having a long usable period, a low environmental load at the time of disposal, and a high working efficiency at the time of use is provided.

The specific structure of each part is not limited to the above-described embodiment. For example, as shown in the modified example of FIG.
2 etc., and in that case, the top plate body 1
04 may be provided detachably with respect to the furniture main body, that is, the storage shelf main body 102a. In addition, the cutting mat 106 is not necessarily a peripheral portion 104 of the top plate body 104.
It is not necessary to be attached to the entire inner area except for the area a.
It can be implemented in various different configurations. Other configurations can be variously modified without departing from the spirit of the present invention.

<Second Embodiment> A furniture top plate 201 according to a second embodiment of the present invention will be described below with reference to FIGS. 5 and 6, and a modification will be described with reference to FIGS. Will be described.

FIG. 5 shows a desk 202 to which the top plate 201 of the present invention is applied. The desk 202 has a top plate main body 204, which is a component of the top plate 201, fixed to the upper end of two left and right side plates 203.

The top plate 201 is characterized in that a desk mat 206 as an upper surface material is detachably mounted on the top plate main body 204 in a state where the desk mat 206 is positioned in a plane direction via an engaging portion A2. In the top plate 201 of the present embodiment, a concave portion 245 is provided above the top plate main body 204 and inside the peripheral portion as the engagement portion A2.

At this time, the upper surface of the edge member 244 is set so as to protrude by a predetermined dimension h1 from the upper surface of the upper frame member 242, and the peripheral portion 20
A rectangular recess 245 surrounded by the inner surface of the frame member 242 and the edge member 244 is formed on the upper surface excluding 4a. That is, the dimension h1 corresponds to the depth dimension of the concave portion 245.

In the recess 245, the desk mat 20 as the upper surface material, which is another component of the top plate 201, is provided.
6 is detachably mounted. This desk mat 206
The plane shape substantially corresponds to the plane shape of the concave portion 245. The material of the desk mat 206 can be freely selected depending on the application. For example, a material such as a chloride resin such as vinyl chloride, an acrylic resin, or an olefin resin such as polypropylene can be used. However, it is limited to recyclable materials and excludes non-recyclable materials such as melamine resin. Desk mat 206
In this embodiment, the thickness h2 is set equal to h1 to make the entire surface of the top plate 201 uniform, but it can be freely set depending on the application.

With such a configuration, the recess 245 of the top plate main body 204 removably positions the desk mat 206, thereby eliminating the problems of cost, environmental load, and work efficiency of the conventional product. Is done.

First, since the desk mat 206 is detachable from the concave portion 245, problems on cost and environmental load are solved. In other words, only the old or severely damaged desk mat 206 is replaced to replace the top plate body 20.
By continuing the use of No. 4, surface contamination / damage does not lead to disposal of the entire top plate 201.

Further, the desk mat 206 can be easily replaced at any time, so that the color layout with the surrounding furniture can be unified, and a plurality of types of desk mats 206 can be properly used depending on the type of work. And a single top plate 201 can support a wide range of usage.

For example, if the desk mat 206 is made of a transparent or translucent material, it can be fixed with a memo or the like beneath it. At this time, since there is no extra part (melamine decorative board) compared to a case where a desk mat is purchased and placed later, the number of parts can be reduced and the number of manufacturing steps can be reduced.

Further, according to the desk mat 206 of the present embodiment, the invention can be carried out without changing the structure of the currently common top plate at all, that is, without investing in equipment or preparing new parts. It is.

In addition, the desk mat 206 and the top plate main body 204 can be collected separately at the time of disposal, and the burden on the environment can be reduced. In particular, since the desk mat 206 is made of a recyclable material, both the desk mat 206 and the top plate body 204 can be recycled, and the burden on the environment is further reduced.

Next, with regard to work efficiency, it is possible to accurately prohibit displacement and cover a wide work area.

That is, when the desk mat 206 is mounted in the concave portion 245 of the top plate main body 204, the desk mat 2
Reference numeral 06 covers substantially the entire area of the top plate 201 at the maximum in a state where the position of the top plate 201 is surrounded by the edge member 244 forming the peripheral edge portion 204a of the top plate main body 204 and the positional shift in the front, rear, left and right directions is prohibited. That is, the person who performs the work can
It is not necessary to dedicate labor and attention to useless work such as fixing and moving the work, and the work can be concentrated on only the object to be processed. This eliminates the need for labor and attention required to prevent the sideways slippage and movement of thick paper, etc. in the conventional case where separate thick paper, etc., was used, eliminating factors that reduce work efficiency, and improving work efficiency and safety. Significantly improve the work environment. Since the desk mat 206 covers substantially the entire area of the top plate 201 at the maximum, the top plate main body 204 is sufficiently prevented from being soiled or damaged.

In this way, the top plate 201 having a long usable period, a low environmental load at the time of disposal, and a high working efficiency at the time of use is provided.

Further, the positioning of the upper surface material to be detachable from the top plate main body can be performed by using an engaging portion having a configuration different from that of the above-described embodiment.
