Description

The present invention relates to a memo clip in which a memo sheet such as paper is temporarily sandwiched and attached to a wall or the like with a magnet, an adhesive, or the like.

As a general technique, a memo sheet such as paper is sandwiched between two sheets of plastic, metal, wood, etc. pressed against each other, and the state of being sandwiched using the restoring force of the spring is held. is there. When sandwiching and removing the paper, it is necessary to operate with both hands to hold the paper with one hand and pinch the two plates with the other hand to open the part that sandwiches the paper. On the other hand, there is one using a structure in which rubber or the like is made in a beard shape at a portion where the paper is sandwiched so that the operation of sandwiching or removing the paper with only one hand can be performed. This is a state where paper is temporarily sandwiched between memo clips by inserting it into an elastic body such as rubber. Since the paper is held in a state of being sandwiched by the elastic force and frictional force of an elastic body such as rubber, it is detached when the paper is pulled out of the elastic body portion such as rubber. As a result, the paper can be sandwiched and removed with one hand. The paper is inserted into the memo clip from the lower side and pinched, and when removing it, the paper is pulled down to remove it. (For example, JP 2001-39070 A)

Japanese Patent Laid-Open No. 2001-39070

In the prior art, when the paper is pulled forward with one hand, it is often the case that not only the paper but also the memo clip is detached from the wall. Pulling the paper forward means pulling the paper perpendicular to the wall where the memo clip is attached. In particular, in a restaurant, when a cook uses an order slip temporarily sandwiched between memo clips to check the order contents, usually, when cooking is finished, the order slip is pulled down from the memo clip and removed. However, since a quick work is required, the order slip is unintentionally pulled to the front, and sometimes the memo clip is attached together with the order slip. In this case, the removed memo clip is removed from the order slip and pasted again on the wall or the like, resulting in poor work efficiency. The present invention makes it easy to remove the paper with one hand, and even when the paper is pulled forward, only the paper is removed and the memo clip remains attached to the wall etc. It is an object to realize a memo clip.

A rotatable wheel 1 is used in a portion where the paper is sandwiched. The wheel 1 presses the paper against the wall 5 or the memo clip body clamping portion 6 by the force of the spring 4. The wheel 1 is fixed to the axle 2, and the axle 2 is fixed to the rotating part 3 so that the rotation of the wheel 1 is not restricted. The rotating part 3 is fixed to the memo clip body 7 so as to rotate up and down. The spring 4 is fixed to the memo clip body 7 and the rotating portion 3. The spring 4 is strong enough to prevent the memo clip body 7 from coming off even if the rotating part 3 rotates and the spring 4 extends so that the wheel 1 has a gap enough to remove the paper from the wall 5 or the memo clip body clamping part 6. Say it. The memo clip main body 7 is attached with a magnet 8 or an adhesive so that the memo clip main body 7 can be attached to an arbitrary place. The memo clip main body 7, the rotating part 3, the axle 2, and the wheel 1 are made of a hard material such as plastic, metal, or wood. In order to increase the friction between the paper and the wheel 1 and improve the holding force of the paper, an elastic body 9 having surface friction such as rubber is attached to the outer periphery of the wheel 1. When the paper is pressed against the ground contact portion of the wheel 1, the wheel 1 rotates and the paper is inserted. Further, in order to improve the holding power of the paper, the wheel 1 rotates only when the paper is inserted, and the wheel 1 is prevented from rotating in the reverse direction when the paper is removed. This can be achieved, for example, by fixing the gear 10 to the axle 2 and hooking the tip of the leaf spring 11 fixed to the rotating portion 3 on the gear 10.

You can easily hold the paper in a memo clip with just one hand, and you can remove it with only one hand. Further, when removing the paper, not only the paper is pulled down and removed, but also the paper can be easily removed without pulling out the whole memo clip even if it is pulled forward. Further, since the sandwiching portion is not hidden by a cover or the like, it can be visually confirmed well, and the operation of sandwiching and removing the paper can be performed smoothly. Furthermore, since the clamping part is a wheel, by attaching a cover shaped like a vehicle with a wheel, the appearance can be enjoyed without hiding the clamping part.

It is a side view of the present invention. It is a front view of the present invention. It is a side view of this invention which has a clamping part in the memo clip main body side. It is a figure which shows the implementation state of this invention. It is a figure which shows the characteristic of this invention.

The form for implementing this invention is demonstrated based on FIG.1, FIG.2, FIG.3.

FIG. 1 is a side view of the present invention, and FIG. 2 is a front view thereof. The rotation unit 3 is fixed to the fulcrum shaft 12 fixed to the memo clip body 7 in which the magnet 8 is embedded so as not to restrict the rotation. The rotation unit 3 can rotate with the rotation center as a fulcrum shaft 12. The memo clip main body 7 and the rotating portion 3 are attached by hooking the end of the spring 4, and a force attracted to each other is exerted by the restoring force of the spring 4. The axle 2 is passed through a hole in the rotating portion 3, and wheels 1 are fixed to both ends of the axle 2. Thereby, the wheel 1 can be rotated without being restricted by the rotating portion 3. An elastic body 9 having a surface friction such as rubber is attached to the outer periphery of the wheel 1. This increases the friction between the paper and the wheel 1. A gear 10 is press-fitted and fixed at the center of the axle 2, and a tip of a leaf spring 11 attached to the rotating portion 3 is brought into contact with the gear 10. The leaf spring 11 is a thin plate made of metal, plastic or the like. When the wheel 1 rotates clockwise, the leaf spring 11 is pushed up by the teeth of the gear 10 and the gear 10 rotates. Conversely, when the wheel 2 rotates counterclockwise, the tooth side surface of the gear 10 hits the end of the leaf spring 11 and stretches, so that the gear 10 cannot rotate. In FIGS. 1 and 2, paper is sandwiched and held between the surface to which the memo clip is attached and the wheel 1.

FIG. 3 is a side view of the present invention having a clamping portion on the memo clip body 7 side. In FIG. 3, paper is held between the memo clip main body 7 and the wheel 1.

A first embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a cross-sectional view showing a state in which the memo clip of the present invention is attached to the wall 5 and the paper 13 is sandwiched. When the paper 13 is sandwiched, if the paper is inserted from the lower side of the wheel 1, the wheel 1 rotates and the paper 13 can be inserted to the memo clip main body 7 side. Since the wheel 1 rotates, the paper 13 can be inserted with a smaller force than when the wheel 1 does not rotate. Thus, the memo paper can be easily sandwiched with one hand. When the paper 13 is inserted and the hand is released, the paper tends to fall down due to its own weight, but the wheel 1 does not rotate in the reverse direction, so that the state where the paper 13 is sandwiched can be maintained. When removing the paper 13 by pulling it downward, the paper 13 should be pulled with a force equal to or greater than the force obtained by subtracting the weight of the paper 13 from the maximum static frictional force generated between the elastic body 9 having surface friction such as rubber and the paper 13. As a result, the paper 13 slips downward and comes off the memo clip.

FIG. 5 is a diagram showing a state in which the paper 13 is pulled out and removed. When the paper 13 is pulled to the front side and removed, the spring 4 extends to create a gap between the wheel 1 and the wall 5, and the paper 13 slips from the wheel 1 and comes off the memo clip.
