Several embodiments will be described below with reference to the drawings. In each drawing, the relative size and position of each member constituting the reinforcing sole plate may be schematically shown.

[First embodiment]
FIG. 1 is a perspective view showing a schematic configuration of a workbench 100 and a reinforcing sole plate 1 according to the first embodiment. The workbench 100 is, for example, a standing horse, and includes a pair of legs 101A, a pair of legs 101B, a footboard 102 spanned between the opposing legs 101A and 101B, and lower ends of the legs 101A and 101B. and a protective cap 103 .

Legs 101A and 101B are foldable, for example. Legs 101A and 101B may be telescopic and adjustable in length. Moreover, the workbench 100 may be used alone, or may be used by connecting a plurality of workbench.

In this embodiment, it is assumed that the width of the footboard 102 in the first direction X is longer than the width in the second direction Y perpendicular to the first direction X. As shown in FIG. A pair of legs 101A are attached to one end of the footboard 102 in the first direction X. As shown in FIG. A pair of legs 101B are attached to the other end of the footboard 102 in the first direction X. As shown in FIG. A pair of legs 101A are connected by a plurality of treads 104A. A pair of legs 101B are connected by a plurality of treads 104B.

When the workbench 100 is viewed parallel to the first direction X, the distance between the lower ends of the pair of legs 101A is wider than the distance between the upper ends. The same is true for the pair of legs 101B. When the workbench 100 is viewed parallel to the second direction Y, the distance between the lower ends of the legs 101A and 101B positioned at the end of one long side of the footboard 102 is wider than the distance between the upper ends. The same applies to the legs 101A and 101B positioned at the end of the other long side of the footboard 102. As shown in FIG.

In such a configuration, the workbench 100 is unstable in the second direction Y, and the workbench may lose its posture and tip over.

The workbench 100 is installed on the ground G. The ground G may be a hard surface such as concrete or a soft surface such as soil. Also, the ground G may be flat or may have undulations.

In the example of FIG. 1, the reinforcing sole plate 1 is placed under the protective cap 103 and attached to the legs 101A and 101B by the tie 3, respectively. The binding tool 3 is passed through a pair of holes 15A and 15B, which will be described later. The binding tool 3 is band-shaped. The material of the binding tool 3 is, for example, resin.

FIG. 2 is a schematic side view of the reinforcing sole plate 1 shown in FIG. FIG. 3 is a schematic plan view of the reinforcing sole plate 1 shown in FIG. FIG. 4 is a schematic rear view of the reinforcing sole plate 1 shown in FIG. Each figure shows the leg 101A and the reinforcing sole plate 1 attached to the leg 101A, but the structure of the leg 101B and the reinforcing sole plate 1 attached to the leg 101B is the same.

The reinforcing sole plate 1 is formed of, for example, one plate-like member. The reinforcing sole plate 1 includes a bottom plate 11 , a support plate 12 , a top plate 13 and a pair of side portions 14 . The bottom plate 11 has, for example, a rectangular shape. The support plate 12 stands up from one side of the bottom plate 11 . In the example of FIG. 3 , the length W1 of the side parallel to the second direction Y of the bottom plate 11 is longer than the length W2 of the side parallel to the first direction X of the bottom plate 11 .

As shown in FIG. 2, the bottom plate 11 has an upper surface 11a that serves as a ground surface for the protective cap 103. As shown in FIG. Further, the support plate 12 has a support surface 12a connected to the upper surface 11a. The support plate 12 is inclined so that the angle between the upper surface 11a and the support surface 12a is an obtuse angle α.

The top plate 13 protrudes from the top of the support plate 12 toward the legs 101A. In the example of FIG. 2, the top plate 13 forms an angle of 90 degrees with the support plate 12, but the angle formed by the top plate 13 and the support plate 12 is not limited to this example. For example, the top plate 13 and the bottom plate 11 may be parallel to each other.

As shown in FIG. 3, the top plate 13 has a groove portion 13a for inserting the leg 101A in the center portion in the second direction Y. As shown in FIG. A width W3 in the second direction Y of the groove portion 13a is wider than a width W4 in the second direction Y of the leg 101A. The groove portion 13a has a shape in which a pair of sides parallel to the first direction X sandwich the leg 101A. Since there is a gap between the groove portion 13a and the surface of the leg 101A parallel to the first direction X, the reinforcing sole plate 1 can move in the second direction Y within the gap.

Since the groove portion 13a is arranged in the central portion of the top plate 13, the relation between the leg 101A and each portion of the reinforcing sole plate 1 is the same regardless of which of the pair of legs 101A the reinforcing sole plate 1 is used for. That is, the reinforcing sole plate 1 can be used for either the pair of legs 101A or the pair of legs 101B without any difference in operation.

The side portions 14 stand upward from sides parallel to the first direction X of the bottom plate 11 . When an operator climbs on the workbench 100, a load is applied to the bottom plate 11 in a direction perpendicular to the ground. Further, by providing the side portion 14, it is possible to prevent the reinforcing sole plate 1 from being caught on the ground when the workbench 100 is moved. Although not shown, the sides of the bottom plate 11 parallel to the second direction Y may also have side portions.

As shown in FIG. 4, the support plate 12 has a mounting portion 15 consisting of a pair of holes 15A and 15B. The pair of holes 15A and 15B are large enough for the binding tool 3 to pass through, and correspond to the sizes of the binding tools 3 of a plurality of types.

A spacer 2 is arranged between the support surface 12a and the side surface 101s of the leg 101A facing the support surface 12a. As in the example of FIG. 3, it is preferable that no gaps are formed between the spacer 2 and the support surface 12a and between the spacer 2 and the side surface 101s when mounted on the workbench 100. FIG. The width W5 of the surface of the spacer 2 parallel to the second direction Y is narrower than the width W4 of the leg 101A. If the width W5 is wider than the width W4, a gap is generated between the surface of the leg 101A parallel to the first direction X and the binding tool 3, and mounting of the reinforcing floor plate 1 on the workbench 100 may become unstable. . When the width W5 is narrower than the width W4, a gap is less likely to occur between the binding tool 3 and the leg 101A, and rattling when the reinforcing sole plate 1 is attached can be suppressed.

In this embodiment, spacer 2 is not fixed to either support surface 12a or leg 101A. However, the spacer 2 may be fixed to the support surface 12a by welding, screwing, or pasting, or may not be fixed to the support surface 12a. By preparing a plurality of spacers 2 having different sizes, it is possible to use the spacers 2 according to the size of the leg 101A of the workbench 100 to be used. The spacer 2 can be made of, for example, an aluminum alloy material.

The protective cap 103 has a dimension slightly larger than the leg 101A. Therefore, when the reinforcing sole plate 1 is attached with the binding member 3 without using the spacer 2 so that the side surface 101s contacts the deep side of the groove portion 13a, the bottom surface and the top surface 11a of the protective cap 103 are not parallel to each other. Gaps may occur between On the other hand, the spacer 2 shown in FIG. 3 has a thickness equal to or greater than the distance between the support surface 12a and the innermost side of the groove 13a. Therefore, if the spacer 2 is used, the bottom surface of the protective cap 103 and the top surface 11a are stably brought into contact with each other while the side surface 101s and the inner side of the groove portion 13a are separated from each other.

Moreover, in the example of FIG. 2, the spacer 2 and the upper surface of the protective cap 103 are in contact with each other. Therefore, the protective cap 103 is difficult to separate from the reinforcing sole plate 1 . On the other hand, a certain gap is created between the spacer 2 and the top plate 13 . Therefore, when a large force is applied to the spacer 2 in the direction toward the top plate 13, the spacer 2 can slightly move upward along the support surface 12a.

As shown in FIG. 4, both ends of the spacer 2 overlap the pair of holes 15A and 15B. Although not shown in FIG. 4, the plane of the leg 101A parallel to the first direction X is also in a positional relationship in which the pair of holes 15A and 15B overlap each other. That is, the minimum distance between the pair of holes 15A and 15B (the distance between the adjacent ends of the holes 15A and 15B) is narrower than the widths W4 and W5, and the maximum distance between the pair of holes 15A and 15B (the distance between the holes 15A and 15B) is narrower than the widths W4 and W5. The distance between the ends separated from each other) is greater than the widths W4, W5. With such a relationship, the binding tool 3 is in close contact with the surfaces of the spacer 2 and the leg 101A parallel to the first direction X, and movement in the second direction Y of the spacer 2 and the leg 101A can be suppressed. If the minimum distance between the holes 15A and 15B is larger than the widths W4 and W5, gaps are generated between the tie 3 and the leg 101A and between the tie 3 and the spacer 2, respectively. In this case, there is a possibility that the movement of the spacer 2 and the leg 101A in the second direction Y cannot be sufficiently suppressed by the binding tool 3 .

When the reinforcing sole plate 1 is attached to the legs 101A and 101B of the workbench 100 as in this embodiment, the contact area of the workbench 100 with the ground is increased. Therefore, it is possible to prevent the legs 101A and 101B from sinking into the ground. Accordingly, the stability of the workbench 100 during installation is improved, and the workbench 100 can be used safely even on soft ground.

In addition, in the examples shown in FIGS. 2 to 4, the reinforcing sole plate 1 protrudes greatly in the second direction Y from the workbench 100 and comes into contact with the ground. This also leads to prevention of overturning in the second direction Y of the work table 100 . From this point of view, as an example, the width W1 is preferably five times or more the width W4.

Further, in the present embodiment, the angle α formed by the upper surface 11a and the support surface 12a is an obtuse angle. In this configuration, the reinforcing floor plate 1 can be attached to the workbench 100 from the inside (left side in FIG. 2) so as to support the side surface 101s. Therefore, the reinforcing sole plate 1 protrudes from the legs 101A and 101B toward the outside in the first direction X as well as in the second direction Y. As shown in FIG. As a result, an effect of preventing overturning of the work table 100 in the first direction X can be expected.

If the angle formed by the upper surface 11a and the supporting surface 12a is an acute angle, the reinforcing sole plate 1 is attached from the outside of the workbench 100 (right side in FIG. 2) so as to support the surface opposite to the side surface 101s. Become. In this case, the reinforcing floor plate 1 protrudes toward the inside in the first direction X, but in this case, almost no overturning prevention effect in the first direction X can be expected.

In the examples shown in FIGS. 2 to 4, the reinforcing sole plate 1 can be formed by bending one plate material. In this case, a reduction in the manufacturing cost of the reinforcing sole plate 1 can also be expected. However, the reinforcing sole plate 1 may be formed by connecting each part by appropriate means such as welding.

As the material of the reinforcing sole plate 1, for example, an aluminum alloy material can be used. When the material is an aluminum alloy material, since the aluminum alloy material is lighter than stainless steel or the like, the total mass of the workbench 100 does not significantly increase even when the reinforcing sole plate 1 is attached. As a result, the burden on the person carrying the workbench 100 is reduced. However, the reinforcing sole plate 1 may be made of other materials.

Since the reinforcing sole plate 1 is attached to the workbench 100 by the binding tool 3, the reinforcing sole plate 1 can be easily attached and detached. Moreover, it is not necessary to form a hole or the like for attaching the reinforcing floor plate 1 to the workbench 100 . Furthermore, since it is not necessary to remove the protective caps 103 from the legs 101A and 101B when mounting the reinforcing sole plate 1, the mounting work is easy.

The reinforcing sole plate 1, the legs 101A, and the spacers 2 are fixed with the ties 3. However, there is a gap between the legs 101A and the grooves 13a, and as described above, the spacers 2 extend slightly along the support surface 12a. can move upwards. Therefore, the reinforcing sole plate 1 can move slightly with one of the sides parallel to the first direction X of the protective cap 103 as a fulcrum, for example. Therefore, when the ground on which the reinforcing sole plate 1 is grounded is inclined in the second direction Y, the reinforcing sole plate 1 can come into contact with the ground over a wide range along the inclination.

Further, by using the spacer 2, the binding device 3 can be tightened in a state in which rattling between the leg 101A and the support plate 12 is suppressed. .

[Second embodiment]
A second embodiment will be described. Elements that are the same as or similar to those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. Configurations and effects not specifically mentioned are the same as those of the above-described embodiments.

FIG. 5 is a side view showing a schematic configuration of the workbench 100 and the reinforcing sole plate 1 according to the second embodiment. Unlike the first embodiment, the reinforcing sole plate 1 further has an anti-slip material 4 . The non-slip material 4 also has a plurality of grooves 41 extending in a direction parallel to the side on which the support plate 12 stands. The groove portion 41 may extend in a direction perpendicular to the side on which the support plate 12 stands, or may have a plurality of projections or recesses instead of the groove portion 41 .

The non-slip material 4 is provided, for example, on the entire lower surface 11b of the bottom plate 11 . The material of the non-slip material 4 is, for example, an elastic body such as rubber or a hard resin. The non-slip material 4 may be adhered to the lower surface 11b, or may be fixed to the lower surface 11b by another method.

By providing the non-slip material 4, the reinforcing sole plate 1 becomes less slippery on the ground. Therefore, further improvement in the stability of the workbench 100 can be expected. Furthermore, if the non-slip material 4 has the grooves 41, such an effect becomes more remarkable. Moreover, when the workbench 100 is installed on a strong surface such as concrete, damage to the lower surface 11b of the reinforcing sole plate 1 can be suppressed. Furthermore, for example, when the workbench 100 is installed on the floor surface of the room, damage to the floor surface can be suppressed.
