Description

[Technical field]

[0001] The present invention relates to a support leg auxiliary tool used for laying an inclined flooring material by filling the gap between a foundation surface and a flooring material, and a support leg using the same. [Background technology]

[0002] In recent years, with the promotion of barrier-free buildings, the number of buildings with outdoor decks and ramps at steps is increasing. A known method of constructing a ramp is to erect support legs on the foundation and place flooring on top of them.

[0003] However, because the slope has an incline, in the case of typical support legs whose top surface is parallel to the foundation surface, gaps inevitably occur between the support legs and the floor material, creating the problem that the floor material cannot be supported stably.

[0004] Conventionally, the applicant of the present invention has been developing a technique for configuring a support leg auxiliary (a so-called spacer) for filling the gap between the support leg and a floor material so as to be able to adjust the thickness (see Patent Document 1).

[0005] On the other hand, a technology that makes it possible to adjust the inclination has been disclosed, which is a leg support aid technology that involves stacking upper and lower components and rotating the upper component to adjust the inclination as desired (see Patent Document 2). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2011-1787 A [Patent Document 2] Special Publication No. 2001-522009 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the technique of Patent Document 1 has a problem in that, although it is possible to adjust the thickness, it is not possible to adjust the inclination.

[0008] Furthermore, the technique of Patent Document 2 has a problem in that it can only accommodate an inclination angle within the range that can be set by the upper and lower members. Furthermore, because the structure engages the top and bottom, it is too thick to be used as a support leg auxiliary, and the support legs cannot be installed close to the contact point between the base surface and the inclined floor material. This results in a long distance between the contact point and the support legs, which causes the floor material to easily flex when a person stands on it.

[0009] The present invention has been made in consideration of the above-mentioned problems, and its object is to provide a support leg auxiliary device and a support leg using the same which not only functions as a spacer by placing it on the support leg to fill the gap between the support leg and the floor material, but also allows the inclination angle of the support leg to be adjusted as desired, thereby enabling the efficient construction of a sturdy floor and reducing construction costs. [Means for solving the problem]

[0010] (Basic configuration) The means adopted by the present inventors to solve the above problems is as follows. The leg support device of the present invention is molded from a plastic material and comprises a disk-shaped main body having planar upper and lower surfaces that are not parallel to each other, and a protrusion that protrudes integrally from the main body.

[0011] In other words, the support leg aid of the present invention has a main body having planar upper and lower surfaces, and a protrusion protruding from the main body, which are integrally molded from a plastic material; the main body is disk-shaped when viewed in a plane, and when the lower surface is placed horizontally, the upper surface is inclined in one direction, giving it a wedge-shaped right-angled triangular cross-section.

[0012] (Configuration of protrusion) The protrusion is A structure that can be rotatably attached to the top plate member of the support leg and can also be rotatably attached to the main body of another support leg auxiliary tool of the same shapeIt is as follows. In detail, the protrusion is formed to protrude from any position of the main body, and preferably protrudes downward from the underside in a pin-like manner, or protrudes downward along the outer periphery of the main body in a rib-like manner, but is configured to include at least a portion that protrudes downward beyond the underside. Furthermore, when the protrusion is made to protrude downward from the lower surface, a configuration can be adopted in which an insertion portion such as a concave surface is formed at a position on the upper surface corresponding to the protrusion.

[0013] By having a portion that protrudes downward from the lower surface portion, the protrusion can be fitted into an insertion portion such as a concave surface provided in a top plate member on which a floor material or the like is placed in the support leg, or into the outer periphery of the top plate member, Same shape It can also be fitted to the insertion portion or the outer periphery of the main body of other leg support aids.

[0014] In this way, the protruding portion is connected to the top plate member of the support leg, or Same shape By fitting it into the main body of another support leg aid, the protrusion acts as a positioner and stopper, regulating misalignment in the planar direction between the support leg aids or between the support leg and the support leg aid. In addition, the protrusion Same shape By fitting the support leg auxiliary tool into the main body of another support leg auxiliary tool, even if multiple support leg auxiliary tools are loaded, the planar deviation between the support leg auxiliary tools is restricted and the support leg auxiliary tools are stabilized, so that multiple support leg auxiliary tools can be stacked.

[0015] The protrusion prevents interference with protrusions provided on the top plate member of the support leg or on the main body of other support leg aids when the support leg aid is rotated (details will be described later). Furthermore, the protrusion can be made to protrude from any position on the main body depending on the position and number of a specified insertion portion, such as a concave surface into which the protrusion is inserted, and multiple protrusions can also be made to protrude. It is also possible to employ a configuration in which the support leg auxiliary device of the present invention is loaded onto the support leg by fitting a protrusion onto the outer peripheral surface of the top plate member of the support leg or another support leg auxiliary device, or the support leg auxiliary devices are stacked on top of each other.

[0016] In this way, the support leg auxiliary device of the present invention is characterized in that by placing one or more support leg auxiliary devices on a support leg, the inclination angle between the upper surface of the topmost support leg auxiliary device and the top plate member of the support leg can be adjusted as desired depending on the inclination angle of the wedge shape of the support leg auxiliary device and the number of support leg auxiliary devices loaded.

[0017] Here, it is also possible to adopt a configuration in which the protruding portion is rotatably attached to the top plate member of the support leg and to the main body of other support leg auxiliary tools. In the above-described configuration in which the protrusion is attached so as to be freely rotatable, by pivoting the support leg auxiliary device of the present invention to the top plate member of the support leg, the support leg auxiliary device can be rotated while still placed on the support leg, thereby changing the direction of inclination of the support leg auxiliary device.

[0018] Furthermore, by pivotally attaching the protrusion to the main body of another support leg auxiliary device, it becomes possible to rotate the support legs relative to each other while multiple support leg auxiliary devices are stacked, thereby making it possible to adjust the inclination angle of all the stacked support legs. Here, in the support leg aid of the present invention, when the main body parts are rotated so that the thinnest parts thereof overlap, the inclination angle is maximum, and when the main body parts are rotated so that the thinnest part of one main body part overlaps the thickest part of the other main body part, they are configured to be parallel to the base surface. In other words, the inclination angle can be adjusted between an angle obtained by multiplying the inclination angle of one support leg assistant by the number of stacks to parallel.

[0019] This inclination angle can be adjusted by rotating any one of the support leg aids when they are stacked, but it can also be adjusted by rotating each of multiple support leg aids. In particular, when two support leg aids are stacked, it is possible to adjust only the inclination angle by rotating the upper and lower support leg aids by the same angle in opposite directions, without changing the overall inclination direction.

[0020] (Threaded hole configuration) The main body may be provided with a plurality of rectangular screw holes with rounded corners and semicircular ends curved along a concentric circle of the main body. The screw holes are preferably arranged symmetrically and evenly about the central axis of the main body, and the angle between the center of the main body and the centers of the two ends of the screw holes is preferably 180 divided by the number of screw holes.

[0021] By configuring the screw hole portion as described above, when multiple support leg auxiliary devices are stacked, there will be a portion that penetrates the multiple screw hole portions regardless of the angular positional relationship of each support leg auxiliary device.

[0022] (Structure of thin-walled groove) The support leg on which the support leg auxiliary device of the present invention is placed is generally composed of a base member that is placed on the foundation surface, a top plate member on which the flooring is placed, and a rod portion that serves as a support axis and has a threaded portion formed therein for raising and lowering the top plate member. In addition to those in which a rod portion protrudes downward from the top plate member, there are also those in which a rod portion protrudes upward from a base member, passes through and is screwed into a plate-shaped top plate member, and the unnecessary portion protruding from the top plate member is cut off for use. In the case of the latter configuration, it is difficult to cut off the rod flush with the top plate member, and generally the rod portion ends up protruding slightly.

[0023] When attempting to place a support leg aid on such a support leg, the slightly protruding rod portion interferes and makes it impossible to place the aid on the support leg. Therefore, it is effective to provide an arc-shaped or circular thin-walled groove in the main body of the leg support aid of the present invention. The arc-shaped thin-walled groove portion referred to here is a thin-walled groove portion shaped to connect the screw hole portions to each other in an arc shape. Further, the circular thin-walled groove portion is not connected to the screw hole, but is an independent thin-walled groove portion formed in a circular shape.

[0024] The thin groove portion is formed to be sufficiently thin compared to the average thickness of the main body portion, and an opening can be formed in the main body portion by breaking it with a blade such as a general cutter. It is also possible to configure the body to break by pressing hard on the center of the body with a finger, without using a blade.

[0025] In this way, when the support leg auxiliary device of the present invention is placed on a support leg of a type in which the rod portion protrudes upward from the top plate member, by providing the thin-walled groove portion of the above-mentioned configuration, it becomes possible to place it on the support leg with the rod portion inserted into the opening.

[0026] (The thinnest part of the outer periphery of the main body) Furthermore, the thickness of the thinnest part of the outer periphery of the disk-shaped main body is preferably 0.5 mm to 2 mm, and more preferably 0.5 mm to less than 1.0 mm. Generally, in injection molding, there is a guideline for the thickness that allows stable molding for each resin, but by setting the thickness in this manner, the minimum thickness that allows injection molding is ensured regardless of which resin is used, and even when loading support leg auxiliary devices to adjust the tilt angle, since the support leg auxiliary device of the present invention is molded to be appropriately thin, delicate angle adjustments can be made by stacking the support leg auxiliary devices.

[0027] Here, since the main body is wedge-shaped in side view, the part where the upper surface and the lower surface are closest to each other is the part where the thickness is the thinnest, and it is more preferable to provide a notch in this part. The shape of the notch is preferably V-shaped or U-shaped in plan view. The cutout portion functions as a guide for the reference position of the angle when the supporting leg aids are stacked to adjust the inclination angle. In addition, the thinnest part of the outer periphery of the main body is the position where the ridge of the notch intersects with the ridge of the outer periphery of the main body. In the case where the notch is provided, the thinnest part is located slightly up the slope of the wedge compared to the case where the notch is not provided, and therefore the upper and lower surfaces are spaced apart by that amount, resulting in a slight increase in thickness. Therefore, if the thickness of the thinnest part when a notch is present is made the same as the thickness of the thinnest part when a notch is not present, it is possible to make the overall thickness thinner by the difference in thickness.

[0028] (Configuration of support legs equipped with support leg auxiliary devices) On the other hand, when the support legs are used to install flooring with a gap of a specified size above the foundation surface, it is possible to adopt a configuration in which the support legs are provided with support leg auxiliary devices (a configuration of support legs equipped with support leg auxiliary devices). In other words, the support leg equipped with a support leg auxiliary device is configured from a base member placed on the foundation surface, a top plate member with a protruding rod portion that is screwed into the base member, and at least one support leg auxiliary device placed on the top plate member.

[0029] The base member has a female thread or male thread formed on a portion protruding from a bottom surface thereof. In addition, a rod portion of the top plate member is screwed into the female threaded portion or male threaded portion of the base member so as to be freely raised and lowered, and the rod portion has a male threaded portion or female threaded portion and is configured to protrude downward from the top plate member.

[0030] A support leg auxiliary device is attached to the tabletop member, and the support leg auxiliary device is composed of a main body portion having planar upper and lower surfaces that are not parallel to each other, and a protrusion portion that protrudes integrally from the main body portion.

[0031] When attaching the tabletop member to the leg support device, The protruding portion is rotatably attached to the top plate member of the support leg, and is also rotatably attached to the main body of another support leg auxiliary tool of the same shape. The tabletop member and the leg support aid are pivotally connected in a detachable or non-detachable manner.

[0032] The support leg of the above configuration is Same shapeThe protruding portion of the other support leg auxiliary is pivotally attached to the main body of the support leg auxiliary pivotally attached to the top plate member. do By doing so, multiple support leg aids are stacked on top of each other. Also It is possible. With this configuration, By rotating one or more of the support leg support tools, the upper surface of the support leg support tool on which the floor material is placed and The inclination angle of the support legs with respect to the top surface can be adjusted arbitrarily without rotating the top plate member. Effect of the Invention

[0033] (The angle of inclination can be adjusted according to the number of items loaded) In the support leg auxiliary device of the present invention, the protruding portion protruding from the main body is pivotally attached to the main body of another support leg auxiliary device, so that the inclination angle between the upper surface of the support leg auxiliary device and the top plate member of the support leg can be adjusted according to the number of items loaded. Therefore, when laying flooring with an incline, such as a slope, there is no need to prepare separate support leg auxiliary devices according to the inclination; by simply changing the number of loads on a single support leg auxiliary device, it can be used for floors with various inclination angles.

[0034] Furthermore, when the protrusion is configured to be inserted into an insertion portion provided inside the outer peripheral surface rather than being fitted onto the outer peripheral surface of the top plate member of the support leg, the underside of the main body of the support leg auxiliary device is configured flat except for the protrusion, so that the support leg auxiliary device is simply placed on the top plate member of the support leg and the protrusion is not restricted in position by the outer peripheral surface. Therefore, the support legs can be pivoted regardless of the outer diameter of the top plate member, and there is no need to prepare different support leg auxiliary tools according to the outer diameter of the top plate member of the support legs.

[0035] These features not only allow the support leg aid to be used as a spacer, but also enable efficient construction of floors with various inclination angles. Furthermore, not only can the cost of materials used in construction be reduced, but inventory management of the support legs and support leg auxiliary devices can be performed efficiently and easily, thereby reducing construction costs.

[0036] (The tilt angle can be adjusted by rotating.) However, when a floor material with a general inclination is installed, the orientation of the support leg auxiliary tool varies, so the inclination angle of the support leg auxiliary tool does not match, and the upper surface of the support leg auxiliary tool and the inclined floor material are not parallel, and a partial gap may be created. In this case, if the top plate member of the support leg is rotated to change the orientation of the support leg auxiliary tool, the vertical height will change.

[0037] However, in the support leg auxiliary device of the present invention, the protrusion is attached to the top plate member of the support leg so that it can be freely rotated, so that only the orientation of the support leg auxiliary device can be changed without rotating the top plate member of the support leg.This makes it easy to adjust the inclination angle without changing the height of the support leg even after installation, and allows efficient installation to match the inclination angle of the floor.

[0038] In addition, if the inclination angle that can be accommodated by the loading combination of the support leg auxiliary tool does not match the angle of the floor material, the upper surface of the support leg auxiliary tool and the floor material may not be parallel, and partial gaps may occur. Even in the case of a delicate inclination angle that cannot be accommodated by simply stacking such support leg auxiliary devices, in the support leg auxiliary device of the present invention, the protrusion is rotatably attached to the main body of the other support leg auxiliary device, so that the relative angle between the underside of one support leg auxiliary device and the upper side of the other support leg auxiliary device changes in response to rotation, and therefore it is possible to freely adjust only the relationship in inclination angle between the stacked support leg auxiliary devices without rotating the top plate member of the support leg.

[0039] (Effect of providing screw holes) The multiple screw holes provided in the main body of the support leg auxiliary tool have portions that penetrate the multiple screw holes regardless of the angular relationship of the stacked support leg auxiliary tools. This allows the support legs and support leg auxiliary tools to be screwed together regardless of the angular relationship even when multiple support leg auxiliary tools are stacked, and the angle will not change due to the support leg auxiliary tool moving during installation. This improves the workability of construction, making it possible to construct the floor efficiently.

[0040] (Effect of providing thin grooves) When the support leg auxiliary device of the present invention is placed on a support leg in which the rod portion protrudes upward from the top plate member, the provision of an arc-shaped or circular thin-walled groove portion makes it possible to place the device on the support leg with the rod portion inserted into the opening, so that one support leg auxiliary device can be used on various types of support legs. This eliminates the need to prepare multiple types of support leg auxiliary tools depending on the support leg to be installed, which not only reduces the cost of materials for construction, but also enables efficient inventory management and reduces construction costs.

[0041] (The effect of making the thinnest part a specified thickness) Furthermore, by setting the thickness of the thinnest part of the main body to 0.5 mm to 2 mm, when the device is placed on the top plate member of the support leg, the thickness at the position serving as the reference for tilt can be minimized. This allows it to be positioned close to the ground contact part of an inclined floor material such as a slope, so that the ground contact part and the support legs can be positioned close to each other, and even if a person stands near the ground contact part, the floor material will not sag, resulting in a sturdy floor.

[0042] (Effect of the support leg being equipped with a support leg auxiliary device) On the other hand, the support leg of the present invention equipped with a support leg auxiliary device has a tabletop member that can be raised and lowered freely using a screw portion, so that the gap between the tabletop member and the floor material can be adjusted by rotating the tabletop member.By being equipped with the support leg auxiliary device, not only does it function as a spacer to adjust the gap between the tabletop member and the floor material, but the inclination angle can also be adjusted as desired.

[0043] In addition, because the support legs are equipped with support leg auxiliary tools in advance, the time required to place the support leg auxiliary tools one by one during construction is eliminated, and the inclination angle between the upper surface of the topmost support leg auxiliary tool on which the flooring material is placed and the top surface of the support leg can be adjusted as desired without rotating the top plate member, significantly improving workability and enabling the floor to be constructed efficiently.

[0045] Example 1 A first embodiment of the present invention will be described with reference to Figures 1 to 7. Note that the present invention is not limited to the aspects shown in these drawings.

[0046] (Basic configuration) The leg support aid 1 in this embodiment is composed of a disk-shaped main body 2 and a protruding part 3 that protrudes integrally from the main body 2, as shown in Figs. 1(a) and (b).

[0047] Here, the leg support aid 1 of this embodiment is made of a single material, and in this embodiment, it is formed by injection molding polypropylene, which is an inexpensive and lightweight material. Note that other resin materials may be used as long as they are inexpensive and lightweight, but materials with good sliding properties are more preferable.

[0048] (Main body configuration) The main body 2 of this embodiment has an upper surface 2a and a lower surface 2b which are planar and not parallel to each other, and has a wedge shape when viewed from the side. In this embodiment, the diameter of the main body 2 is about 100 mm, the thickness t of the thinnest part is about 0.85 mm, and the inclination angle b between the upper surface 2a and the lower surface 2b is 1 / 24 (about 2.4 degrees). Note that this inclination angle b can be changed as appropriate depending on the type of slope to be constructed and the requirements.

[0049] The underside 2b of the main body 2 does not have any part that protrudes downward other than the protrusion 3 described below. Therefore, when placing it on the top surface, it is not limited by the diameter or shape of the top plate member of the support leg, and can be used with a variety of support legs.

[0050] 1(a) and 1(c), a cylindrical recessed insertion portion 2h having a diameter slightly larger than that of a protruding portion 3 described later is formed in the center of the upper surface portion 2a. This insertion portion 2h rotatably receives the protruding portion 3 when the support leg aids 1, 1'... described later are stacked, and serves to pivotally connect one support leg aid 1 and the other support leg aid 1', as well as to limit misalignment in the planar direction.

[0051] Due to the draft angle, the insertion portion 2h is cylindrically recessed and parallel to the protrusion 3, but when the support leg aids 1 are actually stacked, the protrusion 3 is inserted at an inclination angle b relative to the insertion portion 2h. Therefore, the diameter of the insertion portion 2h is set so that the projection 3 can rotate smoothly even if it is inserted at a slight angle, and a gap is generated to the extent that the deviation in the planar direction can be limited within a practical range, and the depth of the gap is preferably sufficiently deeper than the height of the projection 3. In this embodiment, the diameter of the insertion portion 2h is set to about 2.7 mm.

[0052] Moreover, the insertion section 2h is disposed at the center of the main body section 2 so that the leg support aids 1·1'... can be rotated in a stacked state to adjust the overall inclination. In addition, the insertion portion 2h in this embodiment also serves as a pin gate in injection molding.

[0053] In this embodiment, a notch 2f is provided in the thinnest part of the main body 2, and angle indication portions 2j, 2j... are provided at a predetermined angle position near the outer periphery of the upper surface 2a of the main body 2 by means of engraved letters and straight lines. This allows the notch 2f of the upper support leg aid 1 to be visually aligned with the straight line of the mark on the arbitrary angle display section 2j' of the lower support leg aid 1' when the support leg aids 1 and 1' are stacked on top of each other, making it easier to adjust the inclination angle. In this embodiment, the notch 2f is a V-shaped notch.

[0054] Furthermore, a knob 2k is provided at a position opposite the notch 2f to be used as a handle when rotating the support leg aid 1. The knob 2k in this embodiment is a corrugated thin plate having two bulges, and can be easily adjusted by inserting fingers or a tool such as a screwdriver between the bulges to rotate the device.

[0055] In addition, the main body 2 has an uneven thickness due to the inclination of the upper surface 2a. Therefore, it is preferable to prevent sink marks during injection molding by providing a recess on the lower surface 2b side in the relatively thick part near the knob 2k of the main body 2. In this embodiment, the recesses are formed by arranging a plurality of small rectangular recesses at a predetermined interval (not shown), but the recesses may be formed by making the entire surface integrally recessed.

[0056] (Configuration of protrusion) 1(b)(c), the protruding portion 3 in this embodiment is a cylindrical pin with a diameter of about 2.5 mm and a height of about 1.5 mm, protruding downward from the center of the lower surface portion 2b of the main body portion 2. This protruding portion 3 is rotatably inserted into the insertion portion 2h of the stacked support leg aids 1 as described above.

[0057] In addition, this protrusion 3 can also be inserted into the hole 7b near the center among the multiple holes 7b, 7b... that are neatly arranged on the top surface 7a of the support leg 7 on which the support leg auxiliary device 1 shown in Figure 2 is placed. The holes 7b, 7b... in the top surface 7a are lightening holes and also square pilot holes into which the support leg 7 to be placed and the support leg auxiliary tool 1 are screwed together and fixed using a self-tapping screw after the support leg auxiliary tool 1 is placed.

[0058] Therefore, it is preferable to set the diameter of the protrusion 3 so that it can rotate smoothly relative to the holes 7b·7b... of the support leg 7 on which it is placed, and so that a gap is created that can limit misalignment in the planar direction within a practical range.

[0059] (Threaded hole configuration) Two screw holes 2d, 2d each having a semicircular end and rounded rectangular shape that curves along a concentric circle of the side wall 2c are provided on the upper surface 2a of the main body 2. The screw holes 2d, 2d are used to screw the support leg auxiliary tool 1 into the holes 7b, 7b... on the top surface 7a of the support leg 7 on which it is placed. In this embodiment, the screw holes 2d·2d are evenly arranged symmetrically about the central axis of the side wall portion 2c, and the angle a between the center of the side wall portion 2c and the centers of the two end portions of the screw holes 2d·2d is 90 degrees.

[0060] By setting the angle in this way, when two support leg auxiliary devices 1·1' are stacked with their inclination directions in the same or opposite directions, the screw hole portions 2d·2d' exactly overlap, creating a through hole of the same shape as the screw hole portion 2d in a planar view. On the other hand, when two support leg auxiliary devices 1·1' are stacked with their inclination directions shifted by 90 degrees, a circular through hole is formed in plan view by the screw hole portions 2d·2d'. Furthermore, when stacked at the intermediate position, a through hole is formed that has a shape obtained by shrinking the shape of the screw hole portion 2d in the circumferential direction in plan view.

[0061] In this way, regardless of the angular relationship between the two stacked support leg auxiliary devices 1·1', a hole can always be formed that penetrates through the support leg auxiliary device 1, allowing the support leg auxiliary device 1 to be securely screwed to the support leg 7 on which it is placed. The same applies when three or more support leg auxiliary devices 1·1'... are stacked, and when two or more screw hole portions 2d·2d... are provided, the same effect can be obtained by dividing angle a by 180 by the number of screw hole portions 2d·2d....

[0062] (Structure of thin-walled groove) 1(a) and 1(d), thin-walled grooves 2i, 2i in the shape of arcs concentric with the arcs of the threaded holes 2d, 2d are provided between the threaded holes 2d. The thin-walled grooves 2i, 2i have a generally V-shaped cross section, and are locally formed so that the wall thickness is 0.5 mm or less. By inserting a cutter into this V-shaped thin-walled groove portion 2i·2i and cutting out the thin-walled portion along the arc, a doughnut shape having an opening communicating with the screw hole portions 2d·2d is formed, as shown in FIG.

[0063] In this way, by forming an opening in the support leg auxiliary tool 1, it can be placed on not only the support leg shown in FIG. 2, but also the support leg 8 with a protruding rod portion as shown in FIG. 4(a).

[0064] In particular, in this embodiment, the diameter of the thin-walled grooves 2i·2i is set to match the diameter of the rod portions 8b of the support legs 8 from which the rod portions protrude. Therefore, as shown in Fig. 4(b), when the support leg auxiliary devices 1·1' are stacked and placed, the rod portions 8b fit into the inner walls of the open thin-walled grooves 2i·2i to limit misalignment in the planar direction, and the protruding rod portions 8b enable the support leg auxiliary devices 1·1'... to be placed without interfering with each other. In this way, the supporting leg aid 1 of this embodiment can be placed on various types of supporting legs.

[0065] When the support leg auxiliary device 1 of this embodiment is placed on the support leg 8 with the rod portion protruding therefrom, since the underside 2b of the main body 2 has the aforementioned thickness reduction, the main body 2 can be easily penetrated by directly driving a self-tapping screw into any position on the upper side 2a, and the support leg auxiliary device 1 and the support leg 8 with the rod portion protruding therefrom can be fixed together.

[0066] Furthermore, it is possible to provide an array of small dent-shaped recesses at a predetermined interval on the upper surface 2a of the main body 2. In this way, when a self-tapping screw is screwed in, the tip of the screw will be guided into one of the dent-shaped recesses, making it easy and stable to tighten the screw.

[0067] (Adjusting the inclination angle by stacking support leg aids) Next, adjustment of the inclination angle by stacking the leg support devices 1 and 1' will be described with reference to Figs. First, as shown in Fig. 5(b), in this embodiment, two supporting leg aids 1·1' are stacked. Although two are stacked in this embodiment, three or more can also be stacked.

[0068] In this embodiment, as shown in Fig. 5(a), the upper support leg aid 1 and the lower support leg aid 1' are stacked in a rotated state of 90 degrees. At this time, by visually aligning the apex of the notch 2f of the upper support leg aid 1 with the straight line of the angle display part 2j' (the part "1|17") at the part shifted by 90 degrees from the notch 2f' of the lower support leg aid 1', it is possible to easily stack them with a 90 degree shift.

[0069] Also, as shown in FIG. 5(c), the protruding portion 3 protruding from the upper support leg aid 1 is inserted into the insertion portion 2h' of the lower support leg aid 1', and the lower surface portion 2b of the upper support leg aid 1 and the upper surface portion 2a' of the support leg aid 1' are stacked in close contact with each other.

[0070] There is only a slight gap between the protruding portion 3 and the inserting portion 2h', so they are fitted together with almost no play. The protruding portion 3 is cylindrical, and is inserted into the inserting portion 2h', which is also cylindrical. Therefore, even if a force is applied in a planar direction to the upper support leg aid 1 when they are stacked, the protrusion 3 of the upper support leg aid 1 and the inner wall portion of the insertion portion 2h' abut against each other, thereby preventing the upper support leg aid 1 and the lower support leg aid 1' from shifting in a planar direction.

[0071] The inclination angle b of the support leg support devices 1 and 1' stacked in this way with a 90 degree offset is 1 / 17 (approximately 3.6 degrees) as shown in Figure 5(b). This inclination angle b can be arbitrarily adjusted by rotating at least either the upper support leg support device 1 or the lower support leg support device 1'.

[0072] For example, as shown in FIG. 6(a), when the direction of the upper support leg aid 1 and the direction of the lower support leg aid 1' are aligned, the inclination angle b becomes 1 / 12 (approximately 4.8 degrees), and as shown in FIG. 6(b), the inclination angle b between the upper surface 2a of the upper support leg aid 1 and the lower surface 2b' of the lower support leg aid 1' becomes maximum.

[0073] On the other hand, when the upper support leg aid 1 and the lower support leg aid 1' are shifted by 180 degrees as shown in FIG. 7(a), the inclination angle b becomes 0 degrees, and the upper surface 2a of the upper support leg aid 1 and the lower surface 2b' of the lower support leg aid 1' become parallel as shown in FIG. 7(b). This can be used when constructing horizontal sections during construction of slope landings and the like, and by using the same support leg auxiliary tool 1 instead of preparing a separate parallel support leg auxiliary tool, it can help reduce inventory and eliminate the hassle of construction.

[0074] However, when the angle is set to an angle other than 0 or 180 degrees, such as when shifted by 90 degrees, the overall tilt direction when stacked will be midway between the cutout 2f of the upper support leg aid 1 and the cutout 2f' of the lower support leg aid 1', that is, in the case of a 90 degree shift, it will be shifted in the intermediate 45 degree direction. Therefore, when rotating to shift by 90 degrees, the upper support leg auxiliary device 1 and the lower support leg auxiliary device 1' are rotated by 45 degrees each in opposite directions to shift by 90 degrees relative to each other, and it is possible to adjust only the tilt angle b while maintaining the original tilt direction.

[0075] Incidentally, as described above, the screw holes 2d·2d of the upper support leg auxiliary 1 and the screw holes 2d'·2d' of the lower support leg auxiliary 1' always penetrate each other regardless of the angle of deviation, as shown in Figures 5 to 7. This allows the screw to be screwed integrally with the support leg 7 placed by fastening self-tapping screws into the holes 7b·7b... from this penetrated portion, making it possible to fix the support leg 7 placed while maintaining the inclination angle b.

[0076] In this way, by rotating either the upper support leg auxiliary device 1 or the lower support leg auxiliary device 1', or both, the inclination angle b can be adjusted steplessly, and the inclination angle b can be easily fine-tuned on site according to the gradient of the slope to be constructed.

[0077] Example 2 Next, a second embodiment of the present invention will be described with reference to Figures 8 and 9. Note that the same components as those in the first embodiment are given the same reference numerals, and duplicated descriptions will be omitted.

[0078] (Basic configuration) The leg support aid 1 in this embodiment is made up of a disk-shaped main body 2 and protruding parts 3, 3 . . . protruding integrally from the main body 2, as shown in Figs. 8(a) and 8(b).

[0079] (Main body configuration) The main body 2 of this embodiment has planar upper and lower surfaces 2a and 2b that are not parallel to each other, similar to the first embodiment, and the diameter, thickness t of the thinnest portion, and inclination angle b are similar to the first embodiment.

[0080] However, although the lower surface 2b of the main body 2 is flat, the outer circumferential surface of this main body 2 has protrusions 3-3... described below provided at predetermined intervals, and these protrusions 3-3... fit over and fit onto the outer periphery of the top surface 7a of the support leg 7 to be placed and the side wall 2c of the stacked support leg auxiliary tool 1. Therefore, although the diameter of the top surface 7a of the support leg 7 to be placed is limited, the top surface 7a is held by the arc-shaped rib, so that the support leg auxiliary tool 1 is not likely to be damaged even if a strong force is applied in the planar direction, and it has the characteristic of being excellent in strength.

[0081] Meanwhile, a notch 2f is provided in the thinnest part of the main body 2, and a plurality of grooves 2e, 2e... are provided at predetermined angles radially from the center of the main body 2 on the upper surface 2a of the main body 2. This makes it possible to visually align the notch 2f of the upper support leg auxiliary 1 with any groove 2e' of the lower support leg auxiliary 1' when the support leg auxiliary 1 and 1' are stacked on top of each other, making it easy to adjust the inclination angle. In this embodiment, the notch 2f is a V-shaped notch.

[0082] A plurality of holes 2g are formed at predetermined intervals in the main body 2. The holes 2g are pilot holes for screwing in a flooring material F such as a slope, which will be described later, and are systematically formed over the entire surface of the main body 2 so that the material can be screwed in at any position.

[0083] (Configuration of protrusion) 8(c), the protrusions 3·3... in this embodiment protrude radially from the side of the side wall 2c closer to the lower surface 2b, and also protrude below the lower surface 2b. The inner wall portions 3a·3a... formed by the downward protrusions have a cylindrical shape, and the inner diameter thereof is set to be slightly larger than the diameter of the side wall 2c.

[0084] When the support leg support devices 1·1'... are stacked, these protrusions 3·3... fit over and fit over the side wall portion 2c' of the lower support leg support device 1', allowing the support leg support devices 1·1'... to be stacked on top of each other in a rotatable manner.

[0085] In addition, the protrusions 3-3 can also be fitted so as to cover the outer periphery of the top surface 7a of the support leg 7 on which the support leg aid 1 shown in Fig. 2 is placed. This allows the support leg aid 1 to be placed rotatably on the top surface 7a of the support leg 7 on which it is placed.

[0086] In this embodiment, the protrusions 3 are evenly spaced at three positions at 90 degree intervals except for the positions of the notches 2f. Here, it is preferable that the circumferential size of the protrusions 3 is formed to be wide enough to sufficiently cover the side wall 2c, and the protrusions 3 may be formed on the entire side wall 2c except for the positions of the notches 2f.

[0087] (Adjusting the inclination angle by stacking support leg aids) Next, adjustment of the inclination angle by stacking the supporting leg aids 1 and 1' will be described with reference to FIG. First, as shown in FIG. 9(b), in this embodiment, like the first embodiment, two supporting leg aids 1 and 1' are stacked.

[0088] In this embodiment, as shown in Fig. 8(a), the upper support leg auxiliary tool 1 and the lower support leg auxiliary tool 1' are stacked in a rotated state of 90 degrees. At this time, by visually aligning the notch 2f of the upper support leg auxiliary tool 1 and the groove 2e' of the notch 2f' of the lower support leg auxiliary tool 1', which is shifted by 90 degrees, the two can be easily stacked with a 90 degree shift.

[0089] Also, as shown in FIG. 8(c), the inner wall portions 3a·3a... of the protrusions 3·3... protruding from the upper support leg aid 1 fit along the side wall portion 2c' of the lower support leg aid 1', and the lower surface portion 2b of the upper support leg aid 1 and the upper surface portion 2a' of the support leg aid 1' are stacked in close contact with each other.

[0090] The inner walls 3a and the side wall 2c' are fitted together with almost no rattle since there is only a small gap between them. The protrusions 3 protrude at predetermined intervals along the side wall 2c. Therefore, even if a radial force from the main body 2 is applied to the upper support leg aid 1 when they are stacked, the inner wall portions 3a-3a... of the protrusions 3-3... of the upper support leg aid 1 abut against the side wall portion 2c' of the lower support leg aid 1', thereby preventing the upper support leg aid 1 and the lower support leg aid 1' from shifting radially. The height of the inner wall portions 3a, 3a... is preferably 1 mm or more to prevent the inner wall portions 3a, 3a... from riding up onto the side wall portion 2c', and more preferably 2 mm or less to prevent interference with the lower protrusion portion 3' when stacked.

[0091] In this way, the tilt angle b of the support leg support tools 1 and 1' stacked with a 90 degree offset is 1 / 17 (approximately 3.6 degrees) as shown in Figure 8(b). This tilt angle b can be adjusted arbitrarily by rotating either the upper support leg support tool 1 or the lower support leg support tool 1'. Other combinations are the same as in Example 1.

[0092] As in Example 1, when setting an angle other than 0 degrees or 180 degrees, the upper support leg auxiliary device 1 and the lower support leg auxiliary device 1' can be rotated in opposite directions to adjust only the inclination angle b while maintaining the inclination direction.

[0093] "Example 3" Next, a third embodiment of a support leg to which the support leg aid of the present invention is attached in advance will be described with reference to Figures 10 and 11. Note that the same components as those in the first embodiment are given the same reference numerals, and duplicated descriptions will be omitted.

[0094] (Basic configuration) 10(a) and 10(b), the support leg 4 in this embodiment is configured by placing a support leg auxiliary tool 1, which is made up of a disk-shaped main body 2 and a protruding part 3 protruding integrally from the main body 2, on a top plate member 6 that can be raised and lowered. The support leg 4 in this embodiment also includes the top plate member 6, a bottom surface part 5a that is placed on a base surface B, and a base member 5 that is equipped with a female thread part (not shown). The two support leg auxiliary tools 1·1' are then stacked.

[0095] (Configuration of support leg aid) The support leg auxiliary tools 1·1' used for the support leg 4 in this embodiment are the same as those in embodiment 1. In this embodiment, the thickness t of the thinnest part of the main body of the support leg auxiliary tool 1·1' is set to 0.85 mm, thereby minimizing the thickness of the lower support leg auxiliary tool 1' added to the top surface part 6b of the support leg 4, and it is possible to position the support leg 4 close to the ground contact part of the floor material F such as a slope (described later).

[0096] Incidentally, the supporting leg auxiliary devices 1·1'... may be the same as those in the second embodiment, and the number of layers may be appropriately selected.

[0097] (Configuration of the top plate member) The top plate member 6 of this embodiment has a rod portion 6a protruding from the top plate portion 6b, the rod portion 6a having a male thread portion 6c which is screwed so as to be freely raised and lowered into the female thread portion of the base member 5. When the base member 5 side has a male thread, the male thread portion 6c can be changed to a female thread accordingly.

[0098] In addition, the top surface portion 6b of the tabletop member 6 is circular, and in this embodiment, the diameter is approximately 100 mm, which is the same as the diameter of the main body portion 2 of the support leg aid 1, but it may be smaller or larger than the diameter of the main body portion 2 of the support leg aid 1.

[0099] (About stacking of support leg aids) On the other hand, in this embodiment, the upper support leg aid 1 is stacked with the lower support leg aid 1' in the same direction. The lower support leg aid 1' is stacked such that the protrusion 3' is detachably inserted into the hole 6e in the center of the top plate member, and the lower surface 2b' of the lower support leg aid 1' and the top surface 6b are in close contact with each other.

[0100] In this embodiment, the protrusion 3' is pivotally attached to the central hole 6e so as to be detachable, but the protrusion 3' may be pivotally attached to the central hole 6e so as to be rotatable and non-detachable using a known method. In this case, the leg support aid 1' will not easily fall off the top surface 6b, improving workability.

[0101] 5(c), there is only a small gap between the protrusion 3' and the hole 6e, and between the protrusion 3 and the insertion portion 2h', so they are fitted together with almost no play. The protrusion 3 is cylindrical, and is inserted into the square hole 6e and the cylindrical insertion portion 2h'. Therefore, even if a force in the planar direction is applied to the support leg auxiliary device 1 or the support leg auxiliary device 1' in the stacked state, the protrusion 3 of the upper support leg auxiliary device 1 abuts against the inner wall portion of the insertion portion 2h', or the protrusion 3' of the lower support leg auxiliary device 1' abuts against the inner wall portion of the hole portion 6e, thereby preventing the support leg auxiliary devices 1, 1' from shifting relative to each other and between the support leg auxiliary device 1' and the top surface portion 6b.

[0102] The support leg 4 thus configured is installed with a predetermined gap between the inclined floor material F and the base surface B, as shown in Fig. 11. At this time, because the floor material F has an incline, the gap between the base surface B varies depending on the location. Therefore, the total height of the support leg 4 can be adjusted by rotating the top plate member 6 of the support leg 4 and raising and lowering the rod portion 6a.

[0103] The method of using the support legs 4 in this embodiment is to first determine the inclination angle of the slope by supporting leg 4', which is placed as close as possible to the ground contact area where the floor material F and the foundation surface B intersect, and the other supporting leg 4'', which is placed in the part where the gap between the floor material F and the foundation surface B is largest.

[0104] In detail, the support leg auxiliary tools 1·1 of the two support legs 4'·4'' are set in advance to have a predetermined inclination angle b and are placed in the predetermined position, and then a frame Fa for laying floor material F is placed on the upper surfaces 2a·2a of the support leg auxiliary tools 1·1. This fixes the inclination angle of the frame Fa, and then any number of other support legs 4·4... are placed sequentially between the support legs 4'·4''. The frame Fa and the support legs 4·4'... are then screwed together with self-tapping screws (not shown), and the panel members Fb·Fb... are attached to the frame Fa with self-tapping screws or the like (not shown) for construction.

[0105] Here, when arranging the two support legs 4', 4'', due to the influence of warping of the frame material Fa, etc., a slight deviation in the angle may occur even if the inclination angle b of the support leg auxiliary tool 1·1 is set in advance. Even in such a case, the inclination angle can be fine-tuned by simply rotating one of the support leg auxiliary tools 1·1' without rotating the tabletop member 6, which improves workability. The same applies to any number of other support legs 4·4... that are arranged between the support legs 4', 4''.

[0106] "Example 4" A third embodiment of the present invention will be described with reference to Fig. 7. It should be noted that the present invention is not limited to the embodiment shown in this drawing.

[0107] As shown in Fig. 12(a), the support leg 4 in this embodiment differs from that in Example 3 in that a support leg auxiliary tool 1 similar to that in Example 2 is disposed under a bottom surface portion 5a of a base member 5. Here, as shown in Fig. 12(b), the support leg auxiliary tool 1 overlaps with the bottom surface portion 5a of the base member 5 so that the lower surface portion 2b is in close contact with the bottom surface portion 5a of the base member 5, and the upper surface portion 2a is placed on the foundation surface B during construction.

[0108] Also, similarly to the third embodiment, the inner diameter of the inner walls 3a of the protrusions 3 is set to be slightly larger than the diameter of the side wall 5b of the base member 5. In this embodiment, the diameter of the side wall 5b of the base member 5 is set to 100 mm, the same as the diameter of the side wall 6d of the top plate member 6, and the diameter of the inner wall 3a is set to 100.5 mm, so that the same support leg auxiliary tool 1 can be disposed on both the top surface 6b and the bottom surface 5a.

[0109] The support leg 4 using the support leg auxiliary tool 1 of this embodiment can be used, for example, when a horizontal floor material F is to be laid on an inclined foundation surface B (see FIG. 12(a)). First, the support leg auxiliary tool 1 is installed between the bottom surface portion 5a and the foundation surface B, after being previously adjusted so that the inclination angle b is approximately the same as the angle between the foundation surface B and the floor material F.

[0110] Next, the top plate member 6 of the support leg 4 is rotated to raise and lower the rod portion 6a, thereby adjusting the overall height of the support leg 4 to fit the gap between the floor material F and the foundation surface B. At this time, by rotating the support leg auxiliary tool 1, the inclination angle b of the support leg auxiliary tool 1 can be fine-tuned to match the actual angle between the foundation surface B and the floor material F.

[0111] Then, the floor material F and the top surface 6b of the support leg 4 are fastened together with self-tapping screws (not shown). As with the support leg auxiliary tool 1, the top surface 6b has a plurality of holes (not shown) at predetermined intervals penetrating the entire surface of the top surface 6b so that self-tapping screws can be fastened at any position.

[0112] 『Example 5』 In addition to the first and second embodiments, the support leg aid 1 of the present invention may have a donut-like groove shape as shown in FIG. 13, in which the protruding portion 3 protrudes from a position slightly shifted from the center and the insertion portion 2h has a radius equal to the amount of deviation from the center of the protruding portion 3.

[0113] In this regard, in some support legs 7 on which the support leg auxiliary tool 1 is placed, the hole 7b is provided not in the center of the top surface 7a but in a position shifted from the center for convenience of arrangement. In this case, if the protrusion 3 of the support leg auxiliary tool 1 protrudes from the center of the main body 2, it will be placed with its center offset from the support leg 7 on which it is placed, and the value of the gap between the floor material F designed for construction and the support leg 7 on which the support leg auxiliary tool 1 is placed will differ from the gap value during actual construction.

[0114] Therefore, in this embodiment, by providing a protrusion 3 that protrudes from the center of the main body 2 by the amount of deviation of the hole 7b relative to the central position of the support leg 7 on which it is placed, it is possible to place the support leg 7 on the same axis as the top surface 7a.

[0115] However, when the protrusion 3, which is provided off-center, is inserted into the insertion part 2h provided at the center of the upper surface part 2a and stacked, the central axes of the upper and lower support leg auxiliary devices 1·1' are no longer coaxial. Therefore, when either support leg auxiliary device 1·1' is rotated, the center of rotation is shifted and, as described above, during construction, the gap with the floor material F changes significantly each time the support leg auxiliary device 1·1' is rotated.

[0116] Therefore, in this embodiment, the insertion portion 2h is formed in a donut-shaped groove shape with a radius equal to the offset from the center of the protrusion 3, so that the axes of rotation of the stacked support leg aids 1·1' can be made coaxial while maintaining the inserted state of the protrusion 3. Even in this case, even if a force is applied in the planar direction, the protruding portion 3 is inserted into the insertion portion 2h, and therefore is not easily displaced in the planar direction.

[0117] It is also possible to provide a plurality of protrusions 3·3... at the center of the underside 2b and at offset positions, and then remove unnecessary protrusions 3·3... with a cutter or other blade according to the position of the hole 7b of the support leg 7 to be placed on. This makes it possible for a single support leg auxiliary tool to be used with even more diverse types of support legs.

[0118] 『Example 6』 Next, in the leg support aid 1 of the present invention, as shown in FIG. 14, the V-shaped thin-walled portions of the thin-walled grooves 2i·2i may be perforated with elongated holes provided at predetermined intervals.

[0119] In this embodiment, the thin-walled grooves 2i·2i are provided with thin-walled portions, and the thin-walled portions are perforated, so that the thin-walled portions are more likely to break. Therefore, an opening can be formed in main body portion 2 by pressing firmly with a finger near the center of main body portion 2 without using a blade such as a cutter.

[0120] This eliminates the need to prepare a blade such as a cutter every time an opening is formed, which improves safety and workability.

[0121] 『Example 7』 Furthermore, as shown in Figure 15, the support leg auxiliary device 1 of the present invention can be provided not only with thin-walled groove portions 2i... that connect the screw hole portions 2d... but also with a plurality of thin-walled groove portions 2i... that are concentric with the main body portion 2.

[0122] In this case, in the support legs 8 from which the rod portions protrude, even for support legs 8 having rod portions 8b with different diameters, an opening that matches the diameter of the rod portions 8b can be formed by cutting out any of the thin-walled groove portions 2i·2i... with a cutter.

[0123] As a result, the leg support aid 1 of this embodiment can be placed on a wider variety of supporting legs. [Explanation of symbols]
