Description

[Detailed explanation of the idea] The present invention relates to a floor board removal machine.

Conventionally, as shown in FIGS. 4 and 5, a plurality of supports 63, 63... are attached to the back surface, connecting rings 61 are provided protruding from two adjacent edges, and connecting rings 61 are provided on the remaining two adjacent edges. A synthetic resin rectangular mesh floor plate 6 which can be connected to each other by attaching protrusions 62 and fitting the protrusions 62 from above a ring 61 is known. It is often installed only in the off-season, and the removal work has to be done slowly and manually to unfit and unfit the floorboards 6. This requires long and difficult work, and it is difficult to remove them by force. This has the disadvantage that the fitting portion may be damaged.

SUMMARY OF THE INVENTION An object of the present invention is to provide a floor board extractor that can eliminate the above-mentioned conventional drawbacks and easily remove and remove the floor board fitting portion.

Next, one embodiment of the present invention will be described based on the drawings.

In Figures 1 and 2, reference numeral 1 is a pressed part 11 in which the bottom surface of the front end of a substantially rectangular parallelepiped prism is cut off diagonally, and similarly, the front 2/3 of the upper surface is sloped slightly downward to form a scoop part 12. It is a guide rod, and two wheels 21 and 22 are attached to the bottom surface at the front and rear.

The two guide rods 1, 1 are oriented downward so that the front wheel 21 and front end 13 of one guide rod 1 are in contact with the floor surface, and the rear wheel 22 of the remaining guide rod 1 is oriented downward so that the front wheel 21 and front end 13 of one guide rod 1 are in contact with the floor surface. The front ends 13 of the guide rods 1 are arranged side by side at intervals with the front ends 13 facing upward from the front ends 13 of the guide rods 1 so as to touch each other, and two fin-like projections protrude on the outer surface so as to face each other along the axial direction. It is made movable by a rod shaft (not shown) inserted through a short tube 3 provided therein.

A handle 4 is attached to the upper surface of the guide rod 1, and one handle 4 is bent slightly diagonally downward from the upper end to form a grip portion 41.
The two handles 4, 4 can be opened and closed by a hinge 51, and are connected by a fixture 5 having a partition 52 in the middle. In use, as shown in Figures 3, 4 and 5,
The connecting protrusion 62 of the other floor board 6' is fitted into the connection ring 61 of one floor board 6 from above, and the downward guide rod 1 is moved along the connecting portion of the connected floor boards 6, 6'. The rake part 12 sneaks under the floor plate 6' provided with the connecting protrusion 62, and the holding part 11 of the upward guide rod 1 is inserted into the floor plate 6' provided with the connecting ring 61.
When pushed from above, the connection protrusion 62 of the floor board 6' is lifted and removed from the connection ring 61 of the floor board 6.

Reference numeral 14 shown in FIG. 1 is a protection plate for preventing the support 63 of the floor plate 6' from colliding with the handle 4 during use.

For example, if there is a place where the connection protrusion and connection ring are arranged in the opposite way, such as the white line part of a tennis court, remove the fixing bracket 5 and move the handle 4 of the downward guide rod 1 backward. , after tilting the handle 4 of the upward guide rod 1 forward to swing the downward guide rod 1 upward and the upward guide rod 1 downward, push it forward in the same way.

The width of the short tube separating the two guide rods is preferably 5 to 30 mm. The vertical distance between the tip of the rake part of the downward guide rod and the tip of the holding part of the upward guide rod must be greater than the height of the floor board.
Further, it is preferable to use the guide rod on the side provided with the grip facing downward.

The floor board extractor of the present invention has two guide rods whose front end bottoms are cut out diagonally as described above, which are arranged side by side at a distance, with one front end facing upwards than the other. Since the handle is attached to the top of the guide rod, anyone can easily remove the floor board by simply pushing the floor board removal machine along the joint of the floor board in an upright position. Can work.

If the guide rod is movably attached as in the embodiment, by reversing the upward guide rod and the downward guide rod, the arrangement of the connecting protrusion and the connecting ring can be reversed. It can be easily handled even if
