Abstract

To solve problems: a conventional clothespin requires a large force to open and close a clamping piece by using a repulsive force of a metal spring or a steel material; a small clothespin may slip from a hand and fly around, a body portion may become aged, and a gripping portion may snap out; such a clothespin is very hard to use for children, elderly people and handicapped people; and it has a structurally inverse A-shape and gets easily involved with other clothespins.SOLUTION: Instead of using a metal spring, an elastic material 15 such as a soft resin is used. This clothespin has an opening/closing mechanism that when a compression room 14 is provided at a holding portion 8, which is at the rear end of a recessed shaft scissors piece 7, an elastic material 15 is inserted, and both the holding portions 8 are pressed with fingers, a projection shaft scissors piece 5 is opened while the elastic material 15 is pressed, and that when the fingers are loosened, the projection shaft scissors piece 5 is closed by a restoring force of the elastic material 15, enabling opening and closing with a soft force. In addition, structurally, the entire shape has a pyramid shape, avoiding entanglement with the other clothespins, and opening and closing from a trunk portion 9 is newly possible.SELECTED DRAWING: Figure 1

Description

    The present invention relates to a clothespin.

    Conventional laundry scissors use a metal spring or the like to open and close the clamping piece, but do not use a metal spring or the like and use the inherent flexibility of the resin instead of the spring (Patent Document 1). In addition, there is a plastic spring in which an elastic plastic piece curved in a U-shape is incorporated into the inside of the gripping portion of the clothespin (Patent Document 2).

Japanese Patent Laid-Open No. 2006-147035 Japanese Utility Model Publication No. 05-035093

      Most of the clothespins in circulation are clothespins using C-shaped strong springs. This requires a large force to open the clamping piece. For this reason, it is very difficult to use for children, the elderly and people with handicap. If it is a small clothespin, it will slip and fly from the finger during opening and closing, and if it has been used for a long time, the grip part may suddenly snap and injure. Moreover, since the shape of the clothespin is an inverted A type and the gripping portion spreads obliquely upward, it may be entangled with other hangers. The present invention has been made to solve these problems.

Two scissors pieces having different coupling shaft pieces are fitted to each other at the coupling base shaft portion on one end side to be axially coupled, and a clothespin having a clamping portion having a clamping surface on the other end side. One scissor piece has a convex coupling shaft piece and is called a convex shaft scissor piece, and the other scissor piece has a concave coupling shaft piece and is called a concave shaft scissor piece. The following description will be given with the part side as the rear.
Both the convex shaft scissor piece and the concave shaft scissor piece have a gripping portion on the back side outer surface area of the coupling base shaft portion, and the front region with the gripping region, and therefore, the intermediate point from the front end of the coupling base shaft portion to the tip of the clamping portion. The entire front area excluding the coupling base part is formed as a mutual object, and is expanded in a V shape from the clamping part side to the gripping part and the coupling base part side. Appearance appears.
In the clamping part, the thickness of the outer surface continuous from the gripping part, that is, the front (front) surface and the clamping surface that contacts and opens on the back side is the maximum thickness at the rear end point in a gentle gradient from the tip. This maximum thickness point becomes the contact rotation shaft portion.
The tunnel that extends from there to the front end of the coupling base part is thinned at the point of contact rotation shaft part, cut into a large bay shape until the front end of the coupling base part, and when the clamping surface is closed, it tunnels left and right Appears as a hole.
In the coupling base shaft portion, both the convex coupling shaft piece of the convex shaft scissors piece and the concave coupling shaft piece of the concave shaft scissors piece are coupled by a coupling shaft pin at the center portion in a state where the concave and convex fitting is opposed.
In the concave coupling shaft piece, the side wall rises with the convex coupling shaft piece that fits oppositely on both the left and right sides from the outside, and the side wall rises at the front and rear sides at almost half the height of the side wall The space enclosed in this way is called a compression chamber, but it is an elastic material such as a soft resin block having a soft restoring force on the floor surface of the compression chamber, that is, near the front end on the back side of the gripping portion. Is provided.
In the convex coupling shaft piece, the stem piece trunk is a thick chunk that just fits the space width of the compression chamber of the concave coupling shaft piece, and the pusher rod whose rear end edge protrudes in a bowl shape toward the concave coupling shaft piece side. When the force of the fingertip is applied to the gripping part, the pusher presses the elastic material in the compression chamber, and the clamping part opens with the contact rotation shaft part as the rotation axis. The pressing rod is pushed back by the soft restoring force of the material, the clamping part is closed and the clamping surface is perfectly fitted.
The elastic material compression-type clothespin characterized by the above.

This product uses the restoring force of an elastic material such as soft resin instead of the C-shaped metal spring generally used in clothespins. Soft resin is not a mechanical strength that gradually increases in strength as the clamping piece is opened like a C-shaped metal spring, but the soft strength that is unique to the resin continues and rests while being pressed. However, it is not pushed back strongly, and unlike a metal spring, a strong force is not required. This strength can be adjusted by adjusting the amount of elastic material used.

  Regarding the usage of this product, the conventional laundry scissors open both grips by pushing them with the thumb and forefinger, but in this product there are three ways to open depending on the soft strength and shape. One is to open the thumb and middle finger by inserting them into the hollow parts of the two torso, the second is to open by holding the respective torso with both hands, and the third is to hold both grips with the thumb and index finger as before. It is a method of pushing and opening.

  The conventional clothespin has a reverse A shape with the laundry sandwiched therebetween, and the gripping portion is wide open upward, so that it easily becomes entangled with other clothespins. This product is provided with an open / close system at the end of the base end of the convex scissors and concave scissors, so that the rest of the parts can sandwich the laundry, and there is no tangled protrusion. It does not entangle with other clothespins in a pyramid shape.

  Unlike conventional clothespins, this product has a wide clamping surface and a large crimping area for laundry. This reduces the burden on the fabric to be crimped in combination with the soft strength. Suitable for women's products and decorations with thin fabrics, handkerchiefs and ties.

Hereinafter, embodiments and usage of the present invention will be specifically described.
Washing scissors comprising two scissors pieces having different coupling shaft pieces, which are oppositely fitted to each other at the coupling base shaft portion 1 on one end side and axially coupled, and a clamping portion 3 having a clamping surface 2 on the other end side. One scissor piece has a convex coupling shaft piece 4 and is called a convex shaft scissor piece 5, and the other scissor piece has a concave coupling shaft piece 6 and is called a concave shaft scissor piece 7. The following description will be made with the clamping part 3 side as the front and the coupling base part 1 side as the rear.
Both the convex shaft scissors piece 5 and the concave shaft scissors piece 7 have the gripping portion 8 as the back side outer surface area of the coupling base shaft portion 1, and thus an intermediate point from the front end of the coupling base shaft portion 1 to the tip of the clamping portion 3. The front region is the sandwiching portion 3 and the rear region is the trunk portion 9, and the front region excluding the coupling base portion 1 is formed as a mutual object, and the gripping portion 8 and the coupling base portion 1 side are formed from the sandwiching portion 3 side. The overall appearance appears as if it expands in a V shape.
In the clamping unit 3, the thickness of the outer surface that is continuous from the gripping unit 8, that is, the front (front) surface and the clamping surface 2 that opens and closes oppositely on the back side is the maximum thickness at the rear end point in a gentle gradient from the front end. The maximum thickness point is the contact rotation shaft portion 10.
When the body portion 9 that extends from there to the front end of the coupling base shaft portion 1 becomes thin at a stroke at the point of contact rotating shaft portion 10 and is cut out into a large bay shape until the front end of the coupling base shaft portion 1 and the clamping surface 2 is closed. It appears as a tunnel hole that penetrates to the left and right.
In the coupling base shaft portion 1, both the convex coupling shaft piece 4 of the convex shaft scissors piece 5 and the concave coupling shaft piece 6 of the concave shaft scissors piece 7 are coupled to the coupling shaft pin 11 at the central portion in a state where the concave and convex fitting is opposed. Are bound by.
In the concave coupling shaft piece 6, the side wall 12 rises so as to cover most of the convex coupling shaft piece 4 that fits on the left and right sides from the outside, and the front and rear walls are approximately half the height of the side wall 12. The space formed by the half wall surface 13 rising up is called a compression chamber 14, and has a soft restoring force on the floor surface of the compression chamber 14, that is, near the front end of the back surface side of the gripping portion 8. An elastic material 15 such as a soft resin lump is provided.
In the convex coupling shaft piece 4, the shaft piece trunk portion 16 is a thick lump that just fits the space width of the compression chamber 14 of the concave coupling shaft piece 6, and the rear end edge is bowl-shaped toward the concave coupling shaft piece 6 side. A protruding pressing bar 17 is provided, and when a fingertip force is applied to the grip 8, the pressing bar 17 presses the elastic member 15 of the compression chamber 14, and the clamping unit 3 uses the contact rotary shaft 10 as a rotation axis. When the finger of the gripping part 8 is released, the pressing rod 17 is pushed back by the soft restoring force of the elastic material 15, the clamping part 3 is closed and the clamping surface 2 is perfectly fitted.
The present invention is configured as described above, and a specific usage will be described below.
This product is a clothes pin having a crocodile mouth shape when placed sideways as shown in FIG. 1, and has a shape different from that of the conventional product. In order to use this product, the both clamping parts 3 are opened and inserted into the laundry, and there are three ways to open both the clamping parts 3. This also applies to products in which this product is attached to a folding hanger or the like, but the first method is to use the middle part of the clamping part 3 and the gripping part 8 with one hand and the hollow part of both body parts 9 as the thumb of the right hand. While pressing with the index finger or inserting the middle finger from the right into the hollow part of both torso parts 9, it is supported and enlarged with the thumb. The second method is a method of opening with both hands. In this method, the body 9 of the convex scissors piece 5 and the concave scissors piece 7 is held by the thumb and index finger of both hands and pulled outward. The third method is a method of opening the upper and lower gripping portions 8 by pressing with the fingers in the same manner as a conventional laundry scissors. Which method is used can be selected according to the age of the user, the physical condition, and the handicapped condition.

  What seems to be the most troublesome in the process of washing is a process of hanging the laundry after washing on a hanger or the like. Select the hanger based on the type of laundry, the thickness of the fabric, the size, etc., stretch the basket, and sandwich it with clothespins so that it will not be blown away by the wind or slipped. The clothespins are widely opened and then crimped to the clothing, but a considerable amount of force is required to spread the C-shaped metal spring. Depending on the type of clothespin, the thumb and forefinger alone may be insufficient and the middle finger may be used. If it is a small clothespin, the middle finger cannot be used and only the index finger is used. If the laundry scissors are opened widely and then touched when clothing is crimped, the laundry scissors will come off the fingers and fly away. In addition, the grip 8 may be broken. The cause is that a considerable amount of force is required to compress the C-shaped spring vertically. The product of the present invention does not use a C-shaped metal spring or steel material, and uses the restoring force of the elastic material 15 such as a soft resin, so a large force is not required, and it can be used for children and the handicapped. .

    Unlike the conventional clothespins, this product has a long clamping surface 2 as shown in FIG. 2, and there is a space in the body portion 9 at the end of the sandwiching portion 3 so that it is fully inserted into a hanger such as a wire. Only the coupling base shaft portion 1 protrudes from the hanger. Since the upper part is refreshing, it does not get entangled with each other or with other clothespins as in a conventional clothespin.

    Since the present invention is not a metal spring but a washing scissor that uses the restoring force of the elastic material 15 such as a soft resin, the crimping force is weak. There is a risk that clothing will fall out of the clothespin if the wind is strong or if it is pulled strongly. For this reason, the countermeasure of the clamping surface 2 is required. FIG. 5 shows the product hung on a folded square hanger, but the product on the left side is obtained by processing the shape of the sandwiching surface 2 into a saw-tooth shape, and a corrugated plate-like process is also conceivable. Also, the products on the right side are made by applying a resin material such as silicone to the sandwiching surface 2 so that the laundry does not slip. Can be strengthened.

    The interval between the holding portions 3 when the product is opened, that is, the opening interval is approximately 2 cm depending on the size of the conventional laundry scissors, but the product is a laundry scissors with a crocodile mouth due to its structure. The distance between the openings is 2 cm or more, and when opening with both hands, the opening becomes even larger, close to 3 cm, and can be used for winter thick laundry.

    FIG. 5 is an image diagram when the apparatus is suspended on a folding square hanger. In the conventional clothespin, the C-shaped spring is attached to the frame through a connector. Moreover, although it attaches to a frame through a connection tool using both holes of a holding part, in this product, it can attach directly to a flame | frame using the coupling shaft pin 11. FIG. The attached shape hangs straight like a worm as shown in FIG. Thereby, the number of foldable square hangers that can be suspended can be increased. For example, it is possible to increase the number of four clothes pegs to five in one frame.

    Considering the application of the product of the present invention, it is in the shape of a crocodile mouth when placed sideways as shown in FIG. Since clothes can be inserted as close as possible to the coupling shaft 1, it can be used as a decorative item such as a tie or scarf in addition to a clothespin, as well as a pin for customer identification when storing luggage at a hotel, and shoe storage at an inn. Can also be used.
