Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary tool for a rug smoothing machine.

When installing carpets or similar rugs, the appearance will be impaired unless wrinkles are thoroughly removed. For this reason, it is common for businesses to use a dedicated wrinkle smoothing machine, and a product called KNIEEKICKER (US Pat No. 3374023, manufactured by Robert Consolidated Company, USA) is widely used as a dedicated wrinkle smoothing machine. It is well known among those skilled in the art.

As shown in Fig. 1, this wrinkle smoothing machine has a main body 2 in which a needle 1 for biting into rugs whose protrusion amount can be adjusted is provided on the underside of the head, a knee pad 3, and a movable needle provided on the main body. When the stopper is disengaged, the slide shaft 4 inserted into the cylindrical part at the rear of the main body and the main body 2 are slid relative to each other, and the overall length can be adjusted in stages. 3 is kicked from behind with the knee to push out the rug hooked to needle 1.

However, in order to sufficiently stretch the rug, which has a considerable amount of its own weight and the weight of the worker, using this wrinkle smoothing machine, the worker has to kick the knee pads forcefully and repeatedly, which can cause injury to the worker's knees. In many cases, the time required to smooth out wrinkles also increases.

This invention was made by focusing on the fact that the main body and the riser of such a wrinkle smoothing machine slide relative to each other, and by using this wrinkle smoothing machine or a wrinkle smoothing machine equipped with a similar sliding mechanism, To provide an auxiliary tool that makes it possible to configure a device that can easily and quickly smooth out the wrinkles of a rug without affecting the surface of the carpet. Note that technologies similar in function to the wrinkle smoothing device constructed by combining the auxiliary tool of the present application to be described later and the wrinkle smoothing machine as shown in FIG. There are products shown in No. 93273, etc., but these have an integrated gripping head with claws that lock onto the rug and a part that drives it, so existing knee-pickers can be used. If this is not possible, there will be economic loss.

In addition, when constructing a rug, it may be efficient to smooth out wrinkles by using a knee-kipper or the like to smooth out wrinkles, but this cannot be done due to the previous integration. Therefore, the purpose of the present invention includes solving these problems.

The present invention will be explained below with reference to the attached FIGS. 2 to 6.

As shown in FIGS. 2 and 3, the auxiliary tool 10 of the present invention is inserted between a wall surface A (see FIG. 3) and a rug gripper B along this wall surface and is locked to the gripper B. With the claw 11 at the tip, the first gripping tool 1
2 is provided at the rear end, and a support bar 14 whose rear end is supported by this frame and extends to the edge of the central part of the frame. A booster mechanism includes an inverted U-shaped metal fitting 15 whose intermediate portion is hingedly connected to a horizontal shaft 14a, and an operating lever 16 that extends in the axial direction and whose tip is connected to the upper part of the metal fitting 15. a second hinged to the bottom
As shown in FIG.
The wrinkle smoothing machine main body 2 is detachably supported by the second gripping tool 18, and by operating the lever 16, the wrinkle smoothing machine main body and the slide shaft are slid relative to each other.

As shown in FIG.
, a hinged lid 12c that opens and closes the entrance of the groove 12a by operating the tightening screw 12b at one end, and the groove 12a.
Although the gripping structure is configured by a set screw 12d of the slide shaft 4 that is fitted into the slide shaft 4, other gripping structures may be used as long as the slide shaft 4 can be firmly supported. Moreover, there is no problem even if the upper part is completely fixed to the frame 13. However, as shown in the diagram, axis 1
When hinged to a fixed portion of the frame via 2e, this gripper rotates around the shaft 12e, making it easy to attach and detach the slide shaft 4.

Furthermore, in order to horizontally move the wrinkle smoothing machine main body 2, the support bar 14 needs to be swung up and down slightly when the lever is operated. Some flexibility is provided between the small diameter portion 14b of the support bar 14, which is inserted through the support bar 14 and whose end is fixed with a nut, and the inner surface of the hole of the gripping tool.
(see figure). In addition, as shown in FIG. 6, two support bars 14 can be provided on both sides of the inverted U-shaped fitting 15, and in this case, the rear end of each bar is connected to a shaft 19 at an appropriate location on the frame 13. You can use it to connect the hinge.

The second gripping tool 18 also includes a groove 18a into which the shaft of the wrinkle smoothing machine body 2 is fitted, and a hinged lid 18c that opens and closes the entrance of the groove 18a by operating a tightening screw 18b. If this gripping tool grips the bent neck of the wrinkle smoothing machine main body as shown in the figure, it can reliably support the main body 2 without providing a special set screw.
When gripping a straight portion, it is desirable to provide a set screw corresponding to the screw 12d described above to prevent slipping. However, this gripping tool can also adopt other gripping structures.

Next, as shown in FIG.
The auxiliary tool of the present invention has a movable stopper 6 which is engaged with the knee pusher, and this stopper is biased by a leaf spring 7 in a direction to maintain the engaged state at all times. , second gripper 1
A stopper disengagement screw 20 is attached to 8, and when this screw is tightened, one end of the stopper 6 is pressed and the engagement with the slide shaft is released. Note that the screw 20 is not an essential requirement in this application. This is because the stopper 6 can also be released by other methods, and the auxiliary device of the present invention can also be applied to wrinkle smoothing machines without this stopper or knee rest.

The auxiliary tools explained above are as shown in Fig. 3.
After installing the wrinkle smoothing machine, lock the claw 11 of the frame to the gripper B, and then push down the operating lever 16 as shown by the chain line.
The main body 2 of the wrinkle smoothing machine, which is rotated around point a and supported by the second gripping tool 18, slides forward, and at this time, the main body is moved downward as the support bar 14 rotates the metal fitting 15. As the main body 2 swings, it moves parallel to the floor surface, and therefore, at the beginning of the movement of the main body 2, the needle 1 on the lower surface of the tip bites into the rug C, pushing and stretching the rug with a strong force. On the other hand, when the lever 16 is returned to its original position, the needle 1 is tilted diagonally forward and comes off the mat.
The main body of the wrinkle smoothing machine retreats without moving the rug. Therefore, by sequentially repeating the operation of locking the rug stretched out when the operating lever is pressed down on the gripper B and then returning the lever to its original position, the wrinkles in the rug can be smoothed out.

As explained above, according to the present invention, it is possible to completely remove wrinkles from a rug by simply moving the operating lever up and down, and the lever operation can be performed with a small amount of force due to the use of a boost mechanism. The construction work is easier and faster, and there is no need to worry about hurting your knees like in the past.

In addition, the riser type wrinkle smoothing machine can be attached and removed freely, so depending on the work, you can remove the wrinkle smoothing machine and carry out the work as usual. Efficiency can be improved, and if you already have a riser-type wrinkle smoother, you only need to pay for the auxiliary equipment, which is economically advantageous.
