Description

  The present invention relates to a movable table mounting table, and in particular, can be carried and can be easily installed on a horizontal table top such as a learning desk or dining table to provide a moderately inclined surface. It relates to a table-top installation table.

  In general, a desk such as a learning desk, an office desk, or a dining table is configured such that the top surface of the top plate is horizontal. When reading and writing such as this type of desk, there is a problem that the upper body tends to lean forward and the posture of the operator is worsened.

  On the other hand, desks configured to be able to adjust the angle of the top plate have been proposed. For example, in Patent Document 1 below, a leg member, an upper plate fixed to the upper portion of the leg member, an upper portion of the upper plate, and a seater side end of the upper plate can be rotated about an axis. There is disclosed a desk having a top plate provided on the top plate and a flap member provided on the side opposite to the seated side so as to be changeable between a standing state and a stowed state with respect to the upper plate. The desk is configured such that the inclination angle of the top plate is increased when the flap member is in the standing state than in the retracted state. When performing reading and writing operations on a moderately inclined top plate, the operator is unlikely to lean forward and can take a correct posture naturally.

<First embodiment>
Below, 1st embodiment of the mobile desktop installation stand of this invention is described using FIG. 1 and FIG. FIG. 1 is a side view showing a usage state of a mobile desktop installation table 100 (hereinafter also simply referred to as an installation table 100) according to the first embodiment of the present invention. The installation table 100 is installed on the upper surface 112 of the table 110 having the upper surface 112 and the legs 116, and the user 130 sitting on the chair 120 is writing on the main surface 17 of the installation table 100. Yes. 2A is a side view showing a closed state of the installation table 100, and FIG. 2B is a top view of the installation table 100 in a closed state.

First, the outline | summary of the mobile desktop installation stand 100 of this embodiment is demonstrated.
As shown in FIG. 1, the mobile tabletop mounting table 100 can be carried and can be placed on the upper surface 112 of the table 110 having a horizontal upper surface 112. The top table 10 and the supporting portion 20 are connected to each other. Have. The top plate 10 has a first end portion 12, a second end portion 14 facing the first end portion 12, a substantially flat main surface 17, and a back surface 18 facing the main surface 17. . The couch 20 can support the couchtop 10 by capping between the back surface 18 of the couchtop 10 and the top surface 112 of the table 110. The installation table 100 is configured such that the top plate is moved by the connecting portion 20 in a state where the first end portion 12 is brought into direct or indirect contact with the upper surface 112 and the second end portion 14 is positioned above the first end portion 12. 10 is supported, the state where the main surface 17 of the top plate 10 is inclined at a predetermined angle A with respect to the upper surface 112 (used state) is maintained.

  The installation table 100 having the above configuration is very simple in structure and can be carried. By simply installing it on the upper surface 112 of an arbitrary table 110, it can be used and can easily provide a moderately inclined work surface. can do. In other words, the installation table 100 can provide a work surface that is moderately inclined at a much lower price than a conventional desk having a mechanism for changing the inclination of the top plate. In addition, even when there are a plurality of work place candidates such as a learning desk and a dining table and the work place is changed, the user 130 carries the installation table 100 and changes the work place (the upper surface of an arbitrary table 110). 112), it is possible to perform operations such as reading and writing on a moderately inclined work surface simply by installing the installation table 100. A user 130 who works on a moderately inclined work surface is unlikely to lean forward and easily maintains a gentle S-curve P from the upper body to the lower abdomen. For this reason, the user 130 using the installation table 100 can perform work such as reading and writing without damaging his / her health due to poor posture and without placing a burden on the eyes.

Next, the structure of the installation stand 100 of this embodiment is demonstrated in detail.
The top plate 10 is opposed to the first end portion 12 that is an end portion on the user 130 side, the second end portion 14 that faces the first end portion 12, the substantially flat main surface 17, and the main surface 17. And a back surface 18. The main surface 17 is a surface on the side on which the user performs work when the installation table 100 is in use. The main surface 17 is configured to be substantially flat so that the worker 130 can easily perform the work. “Substantially flat” means that although it is mainly flat, a non-flat portion such as irregularities may be stepped on an arbitrary region. In the present embodiment, the back surface 18 is also configured to be substantially flat, but the back surface 18 is not necessarily flat.

  The top plate 10 of the present embodiment is composed of a plate-like member, and the shape is not limited, but is, for example, a quadrangle. Examples of the plate member include a solid material or a processed plate member. Examples of the processed plate-like member include a plywood member such as a veneer plywood or a printed decorative plywood, or a resin board. Further, the top plate 10 is preferably a solid plate member (solid plate member) when emphasizing texture and strength. For example, solid material, solid laminated material, veneer plywood, oriented strand board Etc. are exemplified. If weight reduction and emphasis on portability are important, a flash-shaped plate member (hollow plate member) may be used. For example, the core material has a honeycomb mesh structure and thin plywood is attached to both sides. A plywood having a hollow core structure can be mentioned.

In the present embodiment, the first end portion 12 on the main surface 17 side is provided with a convex portion 40 extending in the width direction (left-right direction). The convex portion 40 is a portion that slightly protrudes (for example, about several mm to several cm) with respect to the normal direction of the main surface 17. Since the elbow of the user 130 is applied to the convex portion 40, the arm is prevented from slipping off from the inclined main surface 17, so that it is possible to work for a long time with a correct posture.
In the use of the present invention, in order to realize an ideal S-shaped curve P, it is recommended to bring the first end portion 12 close to the front side edge of the upper surface 112 of the table 110. However, the user 130 who works for a long time installs the installation table 100 slightly behind the table 110 in order to prevent the arm from falling off the inclined main surface 17, and the first end portion 12 of the installation table 100 and the table. It has been found that an elbow may be attached to the horizontal portion (not shown) of the upper surface 112 exposed between the front edge of 110 and the front edge. In such an installation mode, the upper body may bend forward and an ideal S-shaped curve P may not be obtained. On the other hand, by providing the convex portion 40, the user 130 can continue working for a long time without difficulty in the recommended usage mode of the installation table 100. Moreover, the convex part 40 can also put work accessories, such as a pencil and an eraser, in the inclined main surface 17, and it contributes also to raising work efficiency.

The convex part 40 in this embodiment arrange | positions the member (thick member) thicker than the top-plate main body 101 which comprises the main surface 17 in the 1st end part 12, and the back surface of the top-plate main body 101 and a thick member Are joined together in a substantially flush state. The top plate main body 101 and the thick member may be made of the same material, or one may be plywood and one may be a solid material. For example, the top plate main body 101 has a plywood solid core with melamine or the like. This is a plywood member in which a decorative veneer made of resin is laminated, and the thick member is made of a solid material such as beech.
Further, as shown in FIG. 2 (b), a modification member 104 such as a tape-like solid material or a plywood member is appropriately disposed on the end surface of the top plate body 101 where the thick member described above is not disposed. It is recommended that the end face not be exposed. In addition, the main surface 17 can be prevented from slipping off the arm during the above-described operation by appropriately applying a non-slip coating to the main surface 17. As the anti-slip paint, a conventionally known anti-slip paint used for a floor surface or the like can be appropriately selected and used.

  The installation table 100 according to the present embodiment has a shelf 50. The shelf 50 is a shelf having a predetermined length extending in the width direction on at least one of the right end edge 16 side or the left end edge 15 side from the center M in the width direction of the main surface 17 (see FIG. 2B). The shelf 50 is formed, for example, by joining a member having a thickness of several millimeters to several centimeters and having a predetermined length to a predetermined portion of the main surface 17. Further, the shelf 50 may be formed integrally with a member constituting the main surface 17. Specifically, in the present embodiment, a shelf 50 is provided on the left edge 15 side of the main surface 17 so as not to interfere with the writing operation of the right-handed user 130. On the inclined main surface 17, work items such as paper, pencils, or erasers can be placed on the shelf 50, thereby improving work efficiency.

  Although not shown, the top plate 10 may have a ferromagnetic layer on the intermediate portion in the thickness direction or on the back surface 18 side. For example, by providing a layer made of a ferromagnetic material such as a thin iron plate or a layer containing a ferromagnetic material between a plywood core material constituting the celestial body 10 and a decorative plate or a thin plywood that stiffens the main surface 17, the ferromagnetic material Layers can be constructed. The ferromagnetic layer may be provided on substantially the entire surface of the top plate 10 or may be selectively provided in a partial region. The top plate 10 having a ferromagnetic layer can be detachably joined to the surface of the main surface 17 with a joining member that attracts the ferromagnetic layer by a magnetic force, and a paper is interposed between the ferromagnetic layer and the joining member. The binder function can be exhibited.

  Examples of the ferromagnetic material constituting the ferromagnetic layer include a simple metal such as iron, cobalt, or nickel, an alloy member such as stainless steel, an iron nickel alloy, or an iron cobalt alloy, or a metal oxide such as magnetite. A metal material is mentioned. In this case, the joining member is a magnet. Alternatively, the ferromagnetic layer may be composed of a magnet, and in this case, the above-mentioned metal material can be appropriately used for the bonding member.

  Next, the solid portion 20 will be described. As shown in FIG. 1, the support portion 20 is a member that supports the top plate 10 with support between the back surface 18 and the upper surface 112. As shown in FIGS. 2 (a) and 2 (b), the support portion 20 in the present embodiment is a single plate-like member whose width dimension is equal to or less than the width dimension of the top plate 10, but is not limited thereto. For example, a plurality of rod-like members may be attached to the back surface 18 to form the solid portion 20 (not shown).

  As shown in FIG. 1, the used portion 20 is extended from the back surface 18 in a direction opposite to the normal direction of the main surface 17. When the installation table 100 is in use, the normal direction of the plate-like member 20 and the normal direction of the main surface 17 are arranged so as to be substantially perpendicular to each other. It is configured that the person's force is satisfactorily received by the clog of the clogged portion 20.

  In the state of use, the top plate 10 supported by the support portion 20 is inclined at a predetermined angle A with respect to the upper surface 112. Although the angle A is not limited, it is preferably 10 degrees or more and 30 degrees or less, more preferably 16 degrees or more and 25 degrees or less, from the viewpoint that the posture of the worker is an ideal S-shaped curve P. More preferably, it is 18 degrees or more and 20 degrees or less. In the present embodiment, since the inclination angle of the rigid portion 20 with respect to the upper surface 112 is fixed in the use state, the angle A is also fixed at a constant angle (for example, 20 degrees).

  In the present embodiment, a plurality of convex cushion portions 106 made of an elastic member such as urethane rubber are provided on the end surface on the first end portion 12 side of the top plate 10 and the end surface on the lower end portion 24 side of the fitting portion 20. (See FIGS. 2A and 2B). Thereby, the installation stability of the installation stand 100 in a use state is achieved, and the workability on the main surface 17 is improved.

  The above-described supporting portion 20 may be fixedly coupled to the back surface 18 so that it cannot operate. However, the upper end portion 22 of the supporting portion 20 is connected to the back surface 18 so as to be rotatable. One connection 30) may be provided. Due to the operation of the connecting portion (first connecting portion 30), the closed state (see FIG. 2A) in which the back surface 18 and the supporting portion 20 are aligned, and the back surface 18 and the supporting portion 20 from the closed state. Can be changed to an open state (see FIG. 1) which is also separated. Thus, by providing the connection part (first connection part 30) and enabling the closed state, the portability and the storage property can be improved.

  In the present embodiment, a first connection portion 30 that is a hinge is used as a connection portion, and a predetermined position of the back surface 18 and the upper end portion 22 of the joint portion 20 are connected by the hinge.
