Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a tool for attaching and detaching a wheel balance weight to be attached to a wheel of an automobile or the like.

[Prior Art] In order to maintain a stable balance during rotation of an automobile wheel, it is more widely used than ever to attach a weight made of one or a plurality of leads to a wheel flange with a stopper. It is being appreciated.

This wheel balance weight (hereinafter, abbreviated as "weight") is formed by fixing a curved stopper to a weight portion, and the elasticity of the stopper is used to make a flange of a wheel between the weight portion and the stopper. Attach it to the wheel by holding it.

Then, when attaching the weight, the weight is hammered in with a hammer or the like, and when detaching the weight, it is removed from the wheel by pulling strongly with an appropriate detaching tool.

[Problems to be Solved by the Invention] Therefore, when the wheel is made of aluminum, the flange of the wheel is scratched, and the wheel cannot be repeatedly mounted at the same location, and it is difficult to remove it.

Further, there is no attachment / detachment tool that can both attach and detach the conventional weight.

By the way, the present inventor has devised a wheel balance weight as shown in FIG.

The wheel balance weight 10 has a weight portion 11
And a fastener 12 fixed to the weight portion 11, and the fastener 12 protrudes from the upper surface of the weight portion 11 and has a curved upper portion and elastically deformable side portions 15;
A connecting part 13 for connecting the curved ends of the both side parts 15, at least one downward projection 16 is provided on the connecting part 13, and at least one projection 17 is provided on the upper surface of the weight part 11. And a pair of detachable hooks 19 and 19 are formed on the inner facing surfaces of the both side portions 15, respectively.

Then, the present inventor has made the wheel balance weight 10
The present invention has been devised and provided with an attachment / detachment tool for wheel balance weights which can be easily attached / detached in accordance with.

[Means for Solving the Problems] In order to achieve the above object, a wheel balance weight attaching / detaching tool of the present invention is a main body having a balance weight supporting step portion disposed at the lower end of the front surface, and a handle at the rear portion, and the main body. Of the magnet and a slide plate having a downwardly bent removal claw at the front end, and the slide plate has the removal claw located in front of the magnet and slides forward and backward on the upper surface of the main body. It is characterized in that it is attached so that it is possible.

[Operation] When the slide plate of the attachment / detachment device is slid to the rear position and the lower surface of the weight part of the wheel balance weight (weight) is placed on the support step part of the main body, the metal fitting of the weight is attracted to the magnet and the weight is attached / detached. Supported by the tip of the tool.

Slide the slide plate of the attachment / detachment tool forward, and with the tip of the slide plate protruding toward the front of the main body, hook the removal claw on the hook for removing the weight, and position the bottom surface of the weight part on the support step. Then, the weight can be pulled at the position of the hook of the fastener with the lower part of the weight as a fulcrum.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

The attaching / detaching tool 1 has a handle 3 integrally formed on a rear portion of a main body 2 made of plastic or the like, and a magnet 4 is attached to a front upper portion of the main body 2 via a frame body 5 fixed to the main body 2. There is. A support step 6 having a positioning recess 6a at the center is provided at the lower end of the front surface of the main body 2. The support step portion 6 is formed in a shape matching the contact surface of the balance weight 10.

Reference numeral 7 is a slide plate having a downward removal claw 8 at the front end and an upward operation piece 9 formed at the rear end by bending, and a pair of guide holes 23, 23 are formed in the longitudinal direction thereof. The slide plate 7 is provided with screws 25, 25 penetrating the washers 24, 24 and the guide holes 23, 23 and fixed to the main body 2, so that the dismounting claw 8 is opposed to the supporting step 6 on the upper surface of the main body 2. It is attached so that it can slide in the front-back direction.

FIG. 2 shows an example of a wheel balance weight suitable for the attachment / detachment tool 1.

Therefore, in order to attach the wheel balance weight 10 to the wheel, first, the slide plate 7 of the attachment / detachment tool 1 is slid to the rear position, and then the lower surface of the weight portion 11 of the wheel balance weight 10 is attached to the main body 2 as shown in FIG. The wheel balance weight 10 is supported on the tip of the attaching / detaching tool 1 by placing the wheel balance weight 10 on the support step portion 6 and adsorbing both side portions 15, 15 of the wheel balance weight 10 to the magnet 4. At this time, the support step portion 6 has the balance weight 10
Since it has a shape that matches the lower surface of the weight portion 11, the balance weight 10 is supported by being matched with the support step portion 6. Next, the handle 3 of the attachment / detachment tool 1 is held, and the wheel balance weight 10 is lifted by the attachment / detachment tool 1 so that the flange 21 of the wheel 20 is inserted between the stopper 12 of the wheel balance weight 10 and the upper surface of the weight portion 11. Just push it in according to the principle. As a result, since the protrusions 16 and 17 press the flange 21 from above and below due to the elastic action of the stopper 12, the wheel balance weight 10 is securely held by the flange 21 and cannot be easily removed.

Next, in order to take out the wheel balance weight 10 from the wheel 20, first slide the slide plate 7 of the attachment / detachment tool 1 so that the tip portion thereof protrudes to the front surface of the main body 2, and then as shown in FIG. 8 is hooked on the hooks 19 for removing the wheel balance weight 10, and the wheel balance weight 10 is placed on the support step 6.
The lower surface of the weight portion 11 is positioned. Then, when the handle 3 of the attaching / detaching tool 1 is pushed down, a large pulling force acts from the detaching claw 8 to the detaching hooks 19 and 19 by levering the contact point between the front surface of the main body 2 and the weight portion 11 as a fulcrum. Therefore, the wheel balance weight 10 is easily separated from the flange 21. In addition, since the stopper 12 is attracted to the magnet 4 after the detachment, the wheel balance weight 10 is smoothly recovered without falling off from the attachment / detachment tool 1.

[Effects of the Invention] As described above, according to the attachment / detachment device of the wheel balance weight of the present invention, both attachment and detachment of the wheel balance weight to / from the wheel can be performed by one unit, and
Due to the lever action at the time of removal, it can be easily removed without requiring a large force.

Moreover, since the supporting step portion of the present invention has a shape that matches the contact surface of the balance weight, the balance weight is supported in conformity with the supporting step portion and can be securely attached and detached. .
