Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a substrate for constructing a reception counter, desk, or the like.

In general, reception counters and school desks are often installed with multiple units arranged in a longitudinal direction and connected, so counters and desks that have independent legs and can stand on their own are
When connected, the legs of each counter or desk adjacent to the connected part will overlap. However, this overlapping leg portion is structurally useless in the connected state, and often becomes a hindrance during use.

In view of the above-mentioned difficulties in connecting counters, desks, etc., the inventor of the present invention first proposed a base for counters, etc., in which there were no leg members at all in the connecting part, and patent application No. 55-170892. No. JP-A-57-
A patent application has been filed as Publication No. 96609.

The previously proposed base for counters, etc. has a hollow interior and a substantially T-shaped or square-shaped side cross section, and the outer skin of the base is formed from a steel plate, and the entire surface of the openings on both sides of the outer skin are connected. After embedding the side members with functionality, foamed resin is injected into the inside of this outer skin and foamed, so that the top plate and the front panel perpendicular to the top plate are formed into an integrated structure. For example, when forming a connected counter,
A required number of the base bodies are connected by abutting the side members at their connecting function portions, and leg members such as panel bodies are attached to the connecting function portions of the side members located at both longitudinal ends of the connected body. Accordingly, a connected counter is constructed in which there are no leg members at all in the connected portion.

The base of the counter etc. mentioned above is revolutionary in that there are no leg members at all in the connecting part.
The side shape of the formed base is approximately T-shaped or approximately
Because of its shape, it has the disadvantage of requiring some ingenuity in transportation and storage.

In view of these points, the present invention takes advantage of the advantage of the previously proposed base such as a counter that there are no leg members at the connecting part when connected, and also makes transportation and storage extremely easy and rational. It was created for the purpose of providing a base for reception counters, etc., and its structure consists of a relatively narrow, backward-facing groove parallel to the top plate surface along the longitudinal direction on the front back of the top plate. A top plate outer skin made of a metal plate with openings on both sides in the longitudinal direction and hollow inside, and a connecting hole penetrating through the outer surface of a side member made of cuttable wood or the like, and at least one hole on the inner surface. A side member having a reinforcing portion formed at a portion corresponding to the rear end portion of the groove of the outer skin and embedded throughout the openings on both sides of the outer skin, and a screw portion formed at both ends in a hole of a connecting portion of the both side members. A top plate member formed of a connecting rod installed between both side members to support the connecting rod, and a suitable synthetic resin injected and foamed into the inside of the top plate outer skin in which the side member including the connecting rod is embedded; and a vertical panel outer skin formed of a metal plate, the upper surface of which is formed in the longitudinal direction into a substantially curved fitting side that fits into the backward groove of the top plate member, and which is open on both sides in the longitudinal direction and hollow inside;
A hole for a connecting portion penetrating through the outer surface of the side member made of a cuttable wood material or the like is formed, and a reinforcing portion having substantially the same shape as the fitting side of the side member is formed at least at the upper end portion of the inner side. A side member buried throughout the openings on both sides of the vertical panel outer skin, a connecting rod constructed between both side members with threaded portions formed at both ends supported by holes in the connecting portion of the side member, and this connecting rod. and a vertical panel member formed of a suitable synthetic resin injected and foamed into the inside of a vertical panel outer skin in which a side member is embedded, and the vertical panel is fitted into a rearward groove of the top plate member in a substantially rectangular shape. It is characterized by having a substantially T-shaped side surface with the mating sides tightly fitted together.

Next, an example of implementation of the present invention will be explained with reference to the drawings.

Figure 2 is a partially cut side cross section of an example of the counter base of the present invention, where A is the top plate member and B is the member A.
It shows a vertical panel member combined with both members A,
B is configured as described below.

Therefore, in Fig. 1A, 1 is a surface obtained by bending a thin steel plate having a substantially rectangular planar shape downward by making both its front and rear ends (left and right in Fig. 1) thicker in the vertical direction. The face plate 2 is a back plate which is applied to the front plate 1 and integrated with the front plate 1 at both the front and rear ends 1e of the front plate 1, and is made by pressing a thin steel plate having a substantially rectangular plane. A groove 2a recessed toward the front end of the surface plate 1 near the front end is formed in the longitudinal direction (perpendicular to the paper surface), and both front and rear ends 2e are brought into contact with the edge 1e of the surface plate 1. It adheres and is formed on the top plate outer skin 1A. Therefore, the outer skin 1A is a hollow body with both longitudinal ends open. still,
2b is the groove 2a on the front side of the back plate 2.
This is a step formed parallel to the .

As shown in FIG. 3A, the top plate outer skin 1A has side members 3 having the same shape as the openings embedded in the openings at both longitudinal ends (upper and lower ends in FIG. 3A). The member 3 is provided with a connecting portion on its outer surface and a reinforcing portion on its inner surface.

In this embodiment, the connecting portion is formed by drilling through holes 3a, 3a in both the side members 3, 3 along the longitudinal direction of the outer skin 1A and having counterbore portions on the outer surface side. Two connecting rods 4 having threaded portions 4a formed at both ends are inserted between the holes 3a.
The reinforcing portion is constructed by facing the counterbore portion, and the reinforcing portion is formed at the step portion 2 of the outer skin 1A.
A reinforcing metal fitting 5 having a substantially L-shaped front face made of a relatively thick steel plate and having a side cross-sectional shape that is substantially the same as the side cross-sectional shape near b is strengthened using screws, adhesive, etc. on the inner surfaces of both side members 3. It is formed by fixation.

The top plate outer skin 1A formed in the hollow body with the inside closed as described above is made by injecting and foaming the foamed resin 6 through the injection hole (not shown) provided in the side member 3, so that the inside of the outer skin is foamed. It is formed on the top plate member A filled with resin. In the outer skin 1A, the surface of the top plate 1 is coated with a decorative board or painted if necessary.

Next, in FIG. 1B, 11 bends a thin steel plate having a substantially rectangular planar shape with its upper end facing forward (to the left in FIG. 1B), and A groove 2 having a width and a vertical width formed in the top plate outer skin 1A.
12 is a back plate that is applied to and integrated with the plate 11 at the edge 11e of the front plate 11, and is a flat surface. A substantially rectangular steel plate is bent and the edge 12e of the bent portion is welded to the edge 11e of the front plate 11 to be integrated with the front plate 11 to form a vertical panel outer skin 1B having a substantially rectangular side surface. . Therefore, the panel skin 1B is a hollow body with both longitudinal ends open. In addition, the contact edge 11 of the upper part of both plates 11 and 12
e, 12e are formed on the same surface as the upper surface of the above-mentioned fitting side 11a, and the fixing portion 11b is attached to the top plate outer skin 1A.
to function as

The above outer skin 1B is similar to the top plate outer skin 1B,
A side member 13 is embedded in the opening, and the side member 13 has a through hole 13a having a counterbore on its outer surface and a connecting rod 14 peeking through the hole 13a.
The connecting portion by the threaded portion 14a, and the fitting side 11 as a reinforcing member at the upper end portion on the inner surface side of the member 13.
A reinforcing metal fitting 15 having a shape conforming to a is attached.

Vertical panel outer skin 1B formed in this way
A suitable foamed resin 16 is injected into the inside of the side member 13 from the outside to form a vertical panel member B whose entire interior is filled with the foamed resin 16.

When the top plate member A and the vertical panel member B are assembled, adhesive or the like is interposed in the groove 2a of the top plate member A to tightly fit the fitting side 11a of the panel member B, and the fastening portion 11b thereof. Step part 2 on the back side of the member A
b, and by attaching screws or bolts to the reinforcing metal fittings 5 from the lower surface of the fastening portion 11b and fixing it to the top plate member A, it is assembled into a counter base having a substantially T-shaped side surface as shown in FIG. However, when the panel member B is tightly fitted and fixed, the fitting side 11a of the panel member B is reinforced by the reinforcing metal fittings 15 and fitted into the groove 2a of the top plate member A, and the fastening portion 11b is attached to the top plate member A. Since the two members A and B are fixed to the reinforcing metal fittings 5, the connection between the two members A and B becomes extremely strong.

In the present invention, the substantially T-shaped side surface shape of the counter base includes not only the top plate member A and the panel member B assembled in a side T-shape, but also the panel member B as in the above embodiment. This also includes those assembled near the front end of the top plate member A.

The base of a counter or the like in which the top plate member A and the vertical panel member B are integrally joined in this manner is formed into a desk, counter, etc., either alone or in a connected state, as follows.

The bases of the present invention are connected to each other by screwing the connectors 7 or 17 made of screw nuts onto the screws 4a or 14a of the opposing connecting rods 4 or 14 when the sides of the bases are brought together. The connecting rods 4 or 14 connected in this way are pulled outward in the longitudinal direction to tightly connect the base bodies.

Here, the outward tension is caused by the panel-like leg member 8.
is applied to the outer end of the base, and a nut-shaped tightening member 9 is attached to the connecting rod 4 or 1 from the outside of this panel.
When the connecting rod 4 or 14 is tightened by screwing into the threaded portion 4a or 14a of 4, the connecting rod 4 or 14, which was previously connected via the connecting member 7 or 17, is pulled from both ends in the longitudinal direction and tightly tightens the base body sandwiched between them. to be integrated into. Note that even when there is only one base, panel-shaped leg members 8, 8 are attached to both ends of the connecting rod 4 or 14. In addition, the leg member 8
is not limited to a panel shape, and may be of any other suitable shape, as long as it can support the tightening member 9 screwed onto the connecting rods 4 and 14.

The base of the present invention, which can be connected in the manner described above, has the same effect as the previously proposed base for counters, etc. in that there are no leg members in the connecting parts between the bases. Since plate member A and vertical panel member B are formed as separate and independent parts before assembly, and are transported and stored, the number of parts is slightly increased, but the side shapes of both members A and B are simple. Therefore, it is easy to manufacture and suitable for mass production, and since there are few overhanging parts, it is easy to transport and store, and it also occupies less space.

In addition, the base of the present invention has a top plate member A that constitutes the base.
The joint between the vertical panel member B and the vertical panel member B is formed by a rearward facing groove parallel to the top plate surface formed on the back surface of the top plate, and a substantially square-shaped fitting side formed at the top of the panel member corresponding to this groove. Since the bonding area is large and the bonding area is large and the bonding area is large and the bonding strength is increased, this strength is increased by the reinforcing portion formed at the bonding portion of the side members of both members A and B. Since they are complemented, it is possible to exhibit strength comparable to that of a structure in which the top plate member and the vertical panel member are integrally formed in advance from the outer skin stage.

Furthermore, in the base of the present invention, since the side members are made of a cuttable material, the degree of adhesion can be increased by grinding the outer surface of the side members when joining the bases to each other or joining the base and the leg members. , the degree of bonding with the material to be bonded can be improved both in appearance and in substance.

Moreover, since the connecting rods are installed between the side members, the base members or the base member and the leg members can be reliably and firmly joined to each other, so that the integration with the joining partner can be achieved with the above-mentioned joining degree. Coupled with the high value, it can be made easier and even stronger.

In addition, since the base of the present invention is formed by foam filling the inside of the outer skin with synthetic resin, the metallic sound of the outer skin is reduced compared to conventional hollow ones or press-molded ones. It has the advantage that it does not resonate, has high strength, and is lightweight overall.

The present invention is as described above, and in order to form a connected counter or desk that does not require any leg members at the connecting part, it improves the productivity and transportation of the base body that has been proposed previously.
It is extremely useful as a base for counters etc. with improved storage properties.
