Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a general-purpose small jack that can be used as a general-purpose jack for moving and installing furniture, heavy home appliances, etc., as well as for transporting and installing panels when building wall panels.

[0002]

[Prior art]

 Conventionally, when the wall panel 16 is fitted into the anchor bolt 18 embedded in the floor panel 17 as shown in FIG. It is built by carrying it to the vicinity, lifting it up using a lever 19 or a manual jack 20 as shown in FIG. 6, fitting it into the anchor bolt 18, and then lowering the wall panel 16. In addition, even when relatively heavy items such as furniture and heavy home appliances are moved and installed at a predetermined position, a person lifts or carries them on a trolley, etc., and then lowers them to a predetermined position. The actual situation is that they are installed.

[0003]

[Problems to be solved by the device]

 Conventionally, as described above, since there is no device having a jack function for transporting a relatively heavy item such as the wall panel 16 or furniture or heavy home appliances to a predetermined position, and raising or lowering the item, the wall panel 16 When installing, it is difficult to transport the wall panel 16 to the vicinity of the anchor bolts 18, and further, the wall panel 16 is lifted upward by the dedicated lever 19 or the manual jack 20 to be aligned, and then the anchor bolt is placed. Since it has to be fitted into 18 and this is a more difficult task than transportation, it requires a great deal of labor, and its reduction has been desired.

The present invention has been made to solve the above-mentioned problems, and it is possible to easily install wall panels, move and install furniture, heavy home appliances, etc. The purpose of the present invention is to obtain a general-purpose small jack that can be widely used as a jack, is inexpensive, has a simple structure, and is easy to use.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a general-purpose small jack according to the present invention comprises a frame equipped with a caster for movement and an arm whose base end is rotatably mounted on the frame via a shaft. A handle is attached to the distal end, and a handle arm is provided integrally with a lever that forms a predetermined angle with the arm at the base end, and a link that is attached to the pedestal in the same length as the lever and in parallel, It is characterized by comprising a mounting base mounted between the link and the tip of the lever to form a parallelogram link by the mounting base, the link and the lever, and a jack head mounted on the mounting base. is there.

The general-purpose small jack according to the present invention is characterized in that the jack head is detachable and can be exchanged with various attachments.

[0007]

[Action]

 Since the general-purpose small jack according to the present invention is configured as described above, by using this general-purpose small jack, when installing the wall panel, after inserting the jack head into the lower surface of the wall panel, When the handle is turned downward to rotate, the mounting base rises due to the parallelogram link consisting of the mount, link, lever and mount, and the jack head attached to this also lifts, so the wall panel lifts. Since the gantry has casters for moving, the wall panel can be easily transported to the vicinity of the anchor bolt by pushing or pulling the handle as it is. To the wall panel, and then rotate the handle upwards to lower the jack head to move the wall panel. Or the like can be writing denominated fitted to Nkaboruto, relatively transported to weight a predetermined position of the item with, so installation can be performed easily and.

In addition, the jack head is detachable and can be exchanged with various attachments, so by attaching attachments according to the intended use, not only building wall panels but also furniture, heavy home appliances, etc. It can be used for a wide range of purposes such as moving and installing.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing a general-purpose small jack according to an embodiment of the present invention, FIG. 2 is a functional explanatory view showing the jack function thereof, and FIG. 3 is a perspective view showing configurations of various attachments used in the jack. Fig. 4 is an explanatory diagram of how to assemble a wall panel using the jack.

The gantry 1 is composed of a pair of left and right vertical girders 2 that are long in the front-rear direction, and three front and rear shafts 3 that connect the vertical girders 2. The casters 4 are provided and are configured to be movable. A pair of left and right handle arms 5 is rotatably attached to the central portions of the pair of left and right longitudinal girders 2 of the gantry 1 via a shaft 3, and the pair of left and right handle arms 5 is A handle 6 is attached to the tip end, and a lever 7 that makes a predetermined angle with the arm is integrally provided at the base end portion.

Further, a pair of left and right links 8 are rotatably attached to the rear portions of the pair of left and right longitudinal girders 2 of the gantry 1 via a shaft 3, and between the link 8 and the tip of the lever 7. 2, a mounting base 9 is pivotally supported, which forms a parallelogram link 10 composed of a mount 1, a lever 7, a link 8 and a mounting base 9 as shown in FIG. A jack head 11 is detachably attached to the attachment base 9 via bolts 12.

As shown in FIG. 3, the mounting base 9 includes a jack head 13 having a wide mounting base, a jack head 14 in which the mounting base is hinged, and a jack in which the mounting base is non-slip. Various attachments such as the head 15 can be exchanged and attached according to the intended use.

However, in the general-purpose small jack according to the above embodiment, the parallelogram link 10 is moved in parallel via the handle arm 5 by rotating the handle 6 in the vertical direction as shown in FIG. Therefore, the jack head 11 can be moved up and down together with the mounting base 9, and can be moved via the casters 4 by pushing or pulling the handle 6.

Next, the operation of building the wall panel by this general-purpose small jack will be described with reference to FIG. 4. First, the tip of the jack head 11 is inserted into the lower surface of the wall panel 16, and then the handle 6 is inserted. By rotating the jack downward and lifting the jack head 11 to lift the wall panel 16, and while moving the jack through the casters 4 in this state, the wall panel 16 is moved to the predetermined position as shown in FIG. 4 (A). Transport it to the built-in position.

Since the anchor bolts 18 are installed on the floor panel 17 at the built-in position, after the wall panel 16 is lifted up from the upper end of the anchor bolts 18, the anchor bolts 18 are aligned with each other. By rotating the handle 6 upward and lowering the jack head 11 as shown in FIG. 4 (B), the wall panel 16 can be fitted into the anchor bolt 18 to be built, and then the jack head 11 The work is completed by pulling out.

By installing jack heads 13, 14 and 15 as various attachments as shown in FIG. 3 according to the intended use, not only the wall panel 16 is installed but also furniture, heavy home appliances, etc. It can be used for a wide range of purposes such as movement and installation, and it will be possible to easily carry and install relatively heavy items to a predetermined position.

[0017]

[Effects of the Invention] As described above, according to the general-purpose small jack according to the present invention, it is possible to determine a relatively heavy item such as installation of a wall panel, movement of furniture, heavy home appliances, and installation. Since it can be transported to a position and installed easily, it is possible to greatly reduce the labor of the operator and the work efficiency, and to operate only by turning the handle up and down. Therefore, it is possible to obtain a general-purpose small jack that is easy to use and has a wide range of uses with good usability.
