Description

Hand grip applicator for car waxing {HAND-GRIP APPLICATOR FOR WAXING VEHICLE}

The present invention relates to a handgrip applicator for car waxing, which is used for waxing to polish the surface of a car body.

Conventional car waxing applicators have been generally in the form of a simple bar-shaped applicator 1 as shown in FIG. 1, and a hand grip applicator 2 in which a handle shape is integrated as a special form has been used.

However, since these conventional applicators 1 and 2 are discarded after being used once or several times, there is a wasteful aspect. On the other hand, since the handle portion 2b constituting the upper portion remains intact, there is room for partial reuse.

Therefore, in consideration of this point, as shown in FIG. 2, the pad part 3a and the handle part 3b are separated and detachably provided in a Velcro method to replace the pad part 3a with a new one An improved applicator 3 for use has been proposed.

However, if such a detachable applicator 3 is not properly attached by matching the centers of the pad part 3a and the handle part 3b, the transmission of force through the handle part 3b to one side of the bottom of the pad part 3a Since it is too biased, the waxing effect is uneven and excessive force is concentrated on a part of the pad part 3a, so that the pad part 3a is separated from the handle part 3b during the waxing operation.

Moreover, the above problem is that even when the centers of the pad part 3a and the handle part 3b are accurately matched and properly attached, the direction of moving the handle part 3b and the force to the pad part 3a during waxing work Since the transmission directions are perpendicular to each other, the pad part 3a has no choice but to move along the handle part 3b by relying only on the bonding force of the Velcros 3c and 3d, and the pad part 3a, which is a cushion material, has an upper surface Even if it moves integrally with the handle part 3b, the bottom surface is left behind due to friction with the vehicle body surface, so it eventually moves while forming a deformable body tilted in the forward and backward direction. Therefore, with this behavior, it is difficult to achieve the effect of uniformly distributing the force of the handle portion 3b to the bottom surface of the pad portion 3a.

Therefore, an object of the present invention is to ensure that the force of the handle portion is evenly distributed to the pad portion in the applicator having a configuration in which the pad portion and the handle portion are detachably attached to each other, and to prevent the problem of separating the pad portion from the handle during waxing It is to provide a hand grip applicator for car waxing that can help.

In order to achieve the above object, the present invention provides a hand grip applicator for car waxing in which a pad part and a handle part are detachably coupled to each other in a Velcro manner, wherein the handle part has a certain height from the bottom surface to which the Velcro hook sheet is attached. A circumferential surface portion is formed, and the pad portion is formed to protrude around the upper surface to which the Velcro fabric that is coupled to match the Velcro hook paper is attached, so that the rim wall portion is formed to accommodate the circumferential surface portion inside the rim wall portion. By forming a space, when the handle part and the pad part are combined, the circumferential surface part is inserted in accordance with the receiving space, and the rim wall part is faceted to the circumferential surface part and supported in the lateral direction. Handgrip for car waxing An applicator is provided.

Here, the pad part has a narrow upper end and a wider lower end in the shape of a truncated cone, the outer circumferential surface of the rim wall part forms an inclined surface by forming the upper end of the truncated cone, and the inner circumferential surface facing the circumferential surface portion may form a vertical surface.

The pad part is made of polyurethane foam (PU Foam) material, and the handle part is made of EVA material. In this case, it is preferable that the height of the inner surface of the edge wall part and the height of the circumferential surface part be 5 mm or more.

As described above, according to the hand grip applicator for car waxing according to the present invention, the rim wall portion is formed around the upper surface of the pad portion and the circumferential surface portion of the lower end of the handle portion is inserted into the receiving space inside the circumferential surface in the lateral direction to the circumferential surface It is supported so that the force of holding the handle and moving in the lateral direction is transmitted through the Velcro and directly transmitted to the rim wall on the side of the pad through the circumferential surface at the bottom, so that the force of the handle is fully transmitted and the pad is applied to the surface of the vehicle body. This allows the pressure to be evenly distributed.

In addition, since the circumferential surface at the bottom of the handle part has an effect of preventing slip between the Velcro coupling surfaces due to the structure in which the rim wall part is supported in the lateral direction, it is possible to prevent a problem in which the pad part is separated from the handle during waxing.
