Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a precast concrete foundation table used to firmly and stably support columns such as various signs, signboards, clothesline, and tents on flat ground, uneven ground, and sloping ground. Regarding
More specifically, the present invention relates to a movable base that has wheels at the bottom to facilitate carrying.

[Prior Art] A conventional base of this type, for example, a base used to stand a clothes stake in a garden, can be mass-produced at low cost, and must be made considerably heavy in order to provide stability. I won't.

Also, considering the market distribution channel, it is necessary to disperse the pillars and foundations separately and carry them. If these can be separated separately, the user can freely use an appropriate column according to the purpose.

As described above, this type of base is made heavy for its use, but it is difficult to carry because it is heavy when it is moved to the installation site or when it is taken in and out of the warehouse.

Furthermore, the installation location is not limited to a flat land, but may be an uneven location or a sloping land. Therefore, it is desired that the angle can be easily changed even under bad conditions and the stability can be secured.

[Problems to be solved by the invention] Technological development in this field is lagging behind and has a number of problems.

In order to change the angle of inclination, some feet are provided under the base table and some of these feet are made to expand and contract.However, the feet bite into the ground and damage the ground. However, there is a problem that the posture is not stable.

Further, if the wheels are provided under the base to make it easy to carry, the stability will deteriorate. Therefore, when the foundation stand is installed on the ground stably, the wheels are installed so that it floats slightly above the ground, and the foundation stand is tilted by pulling on the pillars that are erected on the top surface of the foundation stand, and the wheels are grounded. There is one that allows the table to be moved lightly. However, since the wheels are projected to the side of the base, there are problems that a person stumbles and the usable area around the person is reduced.

Furthermore, in order to eliminate the drawbacks of the wheels protruding laterally of the base as described above, there are those in which the wheels are not projected laterally of the base, but it is necessary to tilt the base. However, there is a problem that such a pillar is an obstacle in the middle of the distribution route or during storage in a warehouse, and the pillar cannot be replaced.

The purpose of the present invention is excellent in stability, adjustable tilt angle, convenient to carry, furthermore, if necessary, the pillar can be set and replaced, and the pillar can be used when carrying. The purpose is to provide a base to solve the above-mentioned problems at once.

Another object of the present invention is to provide a movable base which enables mass production of a solid product at low cost.

[Means for Solving the Problem] The present invention adopts the following means in order to solve the above-mentioned object.

The present invention relates to a base body (1) made of precast concrete, and a pillar having one end planted on the base body (1) and the other end exposed on the upper top surface of the base body (1). An insertion tube (2), a notch (8) opened in the side surface, rear side surface and lower bottom surface of the base stand main body (1), and a shaft (projected from the base stand main body (1) in the notch (8) ( 10, 12), a rolling wheel (9) rotatably supported by the shaft (10, 12) for moving the foundation table body (1) in the notch (8), and the foundation table. A vertical female screw cylinder (5) embedded in the main body (1) and opening on the bottom surface of the base stand main body (1), a screw rod (7) screwed into the vertical female screw cylinder (5), and this screw rod The ground plate (6) fixed to one end of (7) is integrally joined to the pillar insertion pipe (2), the vertical female screw cylinder (5) and the shaft (10, 12). It said foundation block body (1) to buried rebar (14) and a movable foundation base having a.

[Operation] When moving the movable base, stand a support or a lever on the main body. When the pillar is pulled down as a lever and the main body is tilted, the wheel is grounded. If the main body is further tilted with the lever with the contact point between the wheel and the ground as the fulcrum, anything other than the wheel will float.

In this case, further, the main body may be tilted to the left side or the right side, and the whole body may be moved by one wheel or one wheel. On uneven or sloping ground, move the ground plate up and down to set the main body horizontally. In the middle of the market distribution route, the pillar will be separated from the main body.

Embodiment An embodiment of the present invention will be specifically described below in detail with reference to the drawings. FIG. 1 is a front view showing a movable base with the columns removed. Reference numeral 1 denotes the main body of the movable base, which is made of precast concrete. The cross section is roughly trapezoidal and the position of the center of gravity is set slightly lower.

On the top surface of the main body 1, a pillar insertion pipe 2 is erected, and as shown in FIG. 5, the lower portion of the pillar insertion pipe 2 is embedded in the main body 1, so that the pillar insertion pipe 2 is firmly attached. Body 1
It stands up from and is planted in the main body 1. The strut insertion tube 2 is provided with strut tightening screws 3, 3 in the lateral direction, that is, in the direction perpendicular to the axis of the strut insertion tube 2.

At the four corners of the main body 1, vertical female screw cylinders 5, 5 which are opened on the lower bottom surface of the main body 1 and which are threaded on the inner circumference are vertically embedded as shown in FIG.

The vertical female screw cylinders 5, 5 ... have a threaded rod with an external thread on the upper part.
7 and 7 are detachably screwed together, and ground plates 6 and 6 having a large ground area are joined to the lower ends of the screw rods 7 and 7, respectively.

Make two notches 8 and 8 by cutting off the lower part of the two corners made by one side of the main body 1 (identify one side and identify this as the back side) and both sides of this side .
The notches 8 and 8 respectively reach the lower bottom surface of the rear side surface and both side surfaces. The main body 1 between the two cutouts 8, 8 on the left and right remains.

Inside the main body 1 between the notches 8 and 1, one horizontal female screw cylinder 1
2 is buried. Male screws are cut on the inner peripheral surfaces of both ends of the horizontal female screw cylinder 12. The axles 10 are respectively screwed into the female threads on both sides.

As shown in Fig. 6, one axle 10 has a small diameter portion at both ends.
10a and 10b, and male threads are cut on the small-diameter portions 10a and 10b. The small-diameter portion 10b is screwed into one side of the horizontal female screw cylinder 12, and the axle 10 is screwed horizontally to the main body 1.

Therefore, the axle 10 and the screw cylinder 12 form one axle. This single shaft projects horizontally from the body 1 and is in a notch 8.
Rollers 9 are fitted to the axle 10 as shown in FIG. In FIG. 7, 12 and 13 are washers, and 11 is a nut for preventing the wheel 9 from slipping out of the axle 10.

Thus, as shown in FIG. 1, most of the wheels 9,9 provided on the axle 10 are in the notches 8,8, but only a part of the rear part of the wheels 9,9 is provided. Is slightly protruding rearward from the notch 8,8. In other words, a part of the wheel 9 projects slightly rearward from the main body 1 shown by the dotted line in FIG.

The lower end points of the wheels 9 and 9 are located above the lower end surface of the grounding plate 6 at the most raised position (the position shown in FIG. 1), and as a practical matter, the bottom surface of the main body 1 is substantially flush with the bottom surface. It is convenient to have.

The pillar insertion tube 2, the vertical female screw cylinders 5, 5, ..., The horizontal female screw cylinder 12 are three-dimensionally bent as shown in FIGS. 5 and 6 before being embedded in concrete. Are welded to and integrated with the rebar 14, and are firmly embedded in the concrete and coupled to each other. In FIG. 5, reference numeral 4 denotes a water draining hole.

[Operation of Embodiment] When used on a sloping ground, the two ground plates 6, 6 on one side are lowered as shown in FIG. When the ground plate 6 is turned by hand, the screw rod 7 comes out from the vertical female screw cylinder 5.

On level ground, as shown in FIG. 9, the ground plates 6, 6, ... Are raised to the highest position for use. The grounding area of the grounding plate 6 is 7
Since it is considerably larger than the cross-sectional area of, it does not bite into the ground. Even on uneven ground, the ground plate 6 acts to even out unevenness.
Insert the column 15 into the column insertion tube 2 and tighten it with the screws 3 and 3.

When moving the movable base stand main body 1, it is possible to carry the main body 1 by hand with the support column 15 or the support column insertion tube 2, but as shown in FIG. It is convenient to hold it with and pull it down.

When the column 15 is held by hand and pulled down, the rear end side of the support plate 6 serves as a fulcrum P and the entire movable base is rotated, and immediately the rolling wheel 9,
9 touches the ground a. When the column 15 is further pulled, the vicinity of the lower end point of the wheel 9 is grounded and all the support plates 6, 6 ... Float in the air (Fig. 11). Further, when the column 15 is pulled, the main body 1 tilts considerably as shown in FIG.

In the process of tilting the main body 1, there is no other portion that touches the ground a except the rear end of the ground plate 6. This is because the rear end side of the rolling wheel 9 projects rearward from the main body 1.

Since there are only a few portions where the rolling wheels 9 project rearward from the main body 1, the contact points at which the rolling wheels 9 contact the ground a are far away from the main body 1 and do not move backward. In addition, if the user pulls the upper part of the column 15 by hand, the lever can be used to reduce the force for tilting.

Further, as shown in FIG. 12, the main body 1 is considerably inclined and its center of gravity approaches the ground contact point, so that the human power is small. Therefore, the movable base is light and can be pushed and moved on the ground. Even if there is an uneven surface during movement, the pillar 15 can be used to easily change the direction of the entire base by the lever action.

[Advantage of Invention] Since the prop used for carrying is detachable, it can be detached from the main body when unnecessary.
You can easily tilt the movable base using the pillars, float all but the wheel in the air, and use the wheel as a roller for easy transportation.

By raising and lowering the support plate, the main body can be set horizontally on uneven or sloping ground, and it can be set stably without roughening the ground. The distribution route is easy to transport. Since the members are integrated into one by reinforcing bar, the whole is strong and the mass production cost is low.

You can tilt it to the left or right and move it with just one wheel. Also, a lever can be inserted into the column insertion tube instead of the column.
