Description

  The present invention relates to a disassembleable and detachable umbrella.

  In recent years, umbrellas of various designs are on the market, and the range of choices has expanded depending on the individuality of the person. However, when choosing an umbrella at the sales floor, there are some parts that do not match his hobby to some extent, so he had to choose an umbrella with a design closest to his own hobby.

Japanese Patent Publication 2002-142824

  For example, it is conceivable that an umbrella can be assembled, and a favorite item can be selected for each part. However, since it becomes custom-made, there is a drawback that it becomes expensive. On the other hand, although it is conceivable to purchase parts and assemble them by themselves, the umbrella has a complicated structure, and it is difficult to assemble the main bone and the rib in the upper and lower parts so as to be rotatable. In this case, it is conceivable to use a jig or the like in an umbrella factory. However, when a jig is also sold, it becomes expensive, and a cost problem still occurs.

  In order to solve such problems, the present invention is an umbrella having a structure and a component structure that can be easily disassembled and assembled by ordinary persons without using a jig, etc. We offer umbrellas that can get your favorite designs centering on umbrella fabrics and handles that use paints, stickers, etc.

  Specifically, in the present invention, a detachable master bone restraining portion that includes a master bone locking groove that locks the master bone including the end portion of the master bone in the upper handle, and prevents the master bone end portion from coming out of the master bone locking groove. And a rib receiving groove that locks the rib including the end of the rib in the lower part, and a detachable bone receiving that prevents the end of the rib from coming out of the rib receiving groove. By providing the restraining portion, it is possible to provide a disassembleable and detachable umbrella that does not require a jig or a machine, is free to be disassembled and assembled, and has mechanical strength.

  According to the present invention, an umbrella that can be easily disassembled and assembled by an ordinary person without using a jig or the like is provided, and design and other pleasures that can be made to order are provided.

<Embodiment 1 middle bar>

    <First Embodiment General Stick>

  The middle rod (0101) is a component constituting an umbrella mandrel. Also called the middle shaft or shaft. The upper end of the center rod is provided with a stone bump (0103), and there is an upper crosspiece (0102) for receiving the end of the main bone (0105), and the lower end is a handle (both at hand) required for holding an umbrella. (0108) is mounted on a rod-shaped middle shaft, and can be held and supported by a hand to hold an umbrella. Further, an intermediate portion of the center rod, a portion between the upper handle and the handle, has a lower handle (0104) that is attached to the center rod and can be moved up and down, and supports the end of the receiving bone (0106).

    <Embodiment 1 middle stick material>

  In the past, varieties of wood with a high composition density were preferred because of their robustness, but iron has been used in recent years. For lightness, materials such as aluminum and carbon are sometimes used, and fiber reinforced plastics are also used.

    <Embodiment 1 middle bar size>

  The length of the middle bar is about 80 centimeters, but it is not limited to this value. The handle portion of the middle rod has a length of about 17.5 centimeters and a diameter of about 2.5 centimeters, and the other portions have a diameter of about 1 centimeter, but are not limited thereto. The above is an example of an umbrella for adults, but all numbers are smaller for children's umbrellas. In the case of an umbrella for adults, the length of the handle portion of the middle bar is preferably about 16.0 cm to 19 cm, and the diameter of the middle bar is preferably about 2.0 cm to 3.0 cm. .

    <Embodiment 1 Middle stick Other>

  The middle stick of the umbrella of the present invention has neither an upper repellent or a lower repellent that a conventional umbrella has. The upper cistern has the role of receiving the ribs above the middle bar and below the upper wheel. When opening or folding the umbrella, it is a mechanism that functions using a spring, so it often causes injury to the finger with the upper repellent, which is one of the causes of accidents with the umbrella. I don't have this, so I don't have to worry about it. Moreover, the lower repelling which is in a normal umbrella is not provided below the middle bar. The lower repelling is used when the umbrella is closed and fixed, and this also uses a spring. In the present invention, the lower end of the bottom wheel is pushed in so that it is fixed by straddling the protrusion (0109) at the top of the hand (handle).

The above-mentioned repellency means that the normal umbrella is protruding from the middle stick, and there are two top and bottom. The one that is on the upper side when it is opened is called the upper repellent, and it keeps it from falling when the umbrella is opened. The lower repelling on the lower side is to prevent the umbrella from opening naturally when the umbrella is closed.

The main bone locking groove (0303 FIG. 3) is inserted from above with the locking protrusion (0401 FIG. 4) at the end near the umbrella center of the main bone with the stone protrusion (0302 FIG. 3) side up. The main bone including the support and the end is locked so as to be rotatable. The main bone locking groove is formed by cutting the number of main bones at the upper part of the upper crossbone, and has a structure that allows the end portions of the main bone to be inserted one by one from the top to turn freely.
<Embodiment 1 upper crossbone prevention part for bone removal>

  In order to prevent the end part of the main bone from slipping out of the main bone locking groove, the main bone removal inhibiting part (0301, 0302) is screwed on and off to freely rotate the main bone including the end part over the main bone locking groove. It is free.

  FIG. 3 shows the top of the umbrella in a semi-closed state with the umbrella fabric removed. The upper end of the middle bar has an upper handle, a screw holder (0302) for screwing a stone protrusion, a master bone removal prevention portion (0301) arranged below the master bone, and a master bone inserted into the master bone locking groove (0303). This shows the configuration.

FIG. 4 is a further top view of FIG. It is possible to confirm a structure that locks the main bone tips such as the master bone (0402) inserted into the master bone locking groove (0403) and the master bone tip locking projection (0401) provided at the tip thereof to prevent the bone from coming off.
<Embodiment 1 upper wheel other>

The upper and lower potter's wheel of conventional umbrellas uses a wire to hold the bone, and when the wire is broken, it is separated. However, in the present invention, since the wire is not used, there is no concern. In addition, a nail is usually included in the upper handle for fixing to the center rod, and there is an accident that the nail is pulled out. However, since the present invention does not use the nail, there is no such concern. In the present invention, the upper crosspiece inserts the main bone into the main bone resting groove, and the main bone removal prevention part prevents the upper part of the main bone from slipping out. However, it is all made of resin that prevents the bone-removal suppression part from falling out of the bone-removal.
<Embodiment 1 stone bump>

It has a configuration.

It is said that there is no end to accidents caused by the tip of a child's umbrella. In the present invention, in order to prevent an accident of a child or an adult with respect to a stone bump, it is possible to use a cylindrical nut made of a material such as a plastic instead of a metal rod.
<First Embodiment>
<Embodiment 1 Bottom wheel configuration>

  The potter's wheel is the central part where bones gather. The place where the calcaneus gathers is called the “bottom wheel”. The number of ribs that are locked so that the ribs including the support ends can be rotated from the bottom by inserting the locking projections at the tip of the ribs from above with the stone protrusion side down. In order to prevent the receiving bone locking groove (0501a) that has been cut off and the end of the receiving bone from slipping out from the receiving bone locking groove, the receiving bone including the tip is rotated from above the receiving bone locking groove. It is composed of a screw-removal deterrence preventing portion (0601) that is screwed and detachably plugged.

  FIG. 5 shows the structure of the bottom wheel and the rib lock, with the stone tip down. FIG. 5 (a) shows a state in which the receiving bone is not inserted, and the inserted state is shown in FIG. 5 (b). A screw thread is cut on the upper side surface of the rib receiving groove for receiving the ribs of the lower skull. The inner surface of the cylindrical bone-removal restraining part is cut with a thread that engages with this, and the bone-removing restraining part is screwed into the screw thread of the lower ring so that the bone-removal restraining part locks the bone. It is possible to prevent the top end portion of the receiving bone disposed so as to be rotatable in the groove.

  When closing the umbrella, it is possible to make the handle side inside the bottom pole have a spring structure that holds the handle after passing through the locking projection by cutting the plastic at equal intervals, so that the umbrella does not open Can do.

The receiving bone locking grooves are cut by the number of receiving bones on the lower side of the lower wheel, and the distal ends of the receiving bones gathered on the middle rod side can be inserted one by one here. The bone-removal restraining part has a role of preventing the bone-removal inserted into the groove portion of the bone-retaining locking groove from being pulled out.
<Embodiment 1 Parent bone>
<Embodiment 1 General bone>

The master bone has a function of supporting the umbrella fabric by being locked to the center rod in a form to be inserted into the master bone locking groove of the upper wheel and the other end projecting outside. Moreover, it is connected with the receiving bone latched by the lower crossing by the non-removable support part (0110) provided in the middle of the main bone. This non-detachable support part connects the parent bone and the receiving bone in a non-separable and rotatable manner. Since there are not many needs to combine the main bone and the bone as separate parts, even if this part is inseparably integrated, there is very little dissatisfaction by the customer.
<Embodiment 1 Master bone material>

In recent years, the material of the main bone has been plated with iron mainly. However, carbon fiber and fiber reinforced plastics are now used because it is easy to rust and light. In the present invention, a fiber reinforced plastic is used from the viewpoint of lightness and cost without rust.
<Embodiment 1 bone receiving>
<Embodiment 1 General bone>

Bone (0601) refers to the umbrella bone that connects the lower rod of the center rod to the non-removable support (0110) placed on the parent bone. The non-removable support portion (0602) refers to the joint portion of the parent bone and the receiving bone. In addition, the parent bone and the receiving bone are connected by a part called eyelet. A normal umbrella uses metal for this part, but it is a part where force is applied and is often broken or bent. In the present invention, it is possible to use plastic parts.
<Embodiment 1 Master bone material>

In recent years, the material of the bone has been mainly plated iron like the parent bone, but now carbon fiber, fiber reinforced plastic, etc. are used because it is easy to rust and light. In the present invention, a fiber reinforced plastic is used from the viewpoint of lightness and cost without rust.
<Embodiment 1 umbrella fabric>
<First Embodiment Umbrella Fabric General>

  Umbrella fabric (0107) refers to a state in which rain-prevention fabric used for an umbrella is sewn. Sometimes called a cover. FIG. 8 is a top view of the umbrella cloth removed and placed on a plane, showing the outside. In FIG. 8, a central hole (0801) and a tsuyusaki (0802) are arranged, and a belt (0803) with a snap button that is closed so that a closed umbrella does not open is provided.

  In the present invention, it is possible to remove the umbrella fabric and replace it with an umbrella fabric having a different design by utilizing the fact that disassembly and assembly can be easily performed without jigs even by ordinary people. This provides the same fun as custom-made and dress-up fun. Further, the umbrella fabric is not fixed to the non-removable support portion by bonding or sewing. This is to make it easier to attach and change the umbrella fabric.

  In addition to umbrella fabrics, all plastic members can be drawn and colored with markers, and can be disassembled and assembled without the need for jigs or machinery, so the umbrella as a whole can be used as a canvas substitute. You can also enjoy simple drawing and coloring.

Tsuyasaki (0802 FIG. 8, 0205 FIG. 2, 0111 FIG. 1) is a member disposed at the distal end portion on the outer side of the main bone of the umbrella. In the present invention, it is possible to fix the umbrella fabric to the umbrella by fixing and arranging the bamboo leaf on the outer edge of the umbrella fabric, and inserting the bamboo leaf into the end of the main bone. In addition, the tip of the parent bone is rounded, and the tsuyusaki can be easily attached and detached. When attaching and detaching Tsuyusaki to the tip of the main bone, it is preferable to attach and detach the main bone slightly. When the main bone is made of plastic (including fiber-reinforced plastic), it is easy to bend and easy. When the parent bone is a fiber-reinforced plastic, the tip of the parent bone is preferably coated with a plastic material that does not contain fibers so that the cross section is not exposed. The material for Tsuyusaki is also preferably plastic. More preferred is a flexible plastic. Furthermore, as shown to Fig.9 (a), it is a cylinder diameter, and one part is a partial cylinder, It is good to function as an introducing | transducing part which makes it easy to insert a master bone into a cylinder. FIG. 9B is a cross-sectional view of the cross section of FIG. 9A taken along line A.
<Embodiment 1 Umbrella fabric material>

The materials used for rain umbrellas, umbrellas for rain and rain, and parasols are mainly used for polyester umbrellas that are most used in rain umbrellas, nylon with shrinkage of fabric, T / C that can create a texture by blending polyester and cotton, and vinyl umbrellas. Polyethylene is common. For parasols alone, materials such as cotton and hemp are also used. In the past, PVC (= polyvinyl chloride) was used, but it is no longer used due to the dioxin problem, and polyethylene is mainly used, but there are also drawbacks such as the material being easily scratched and cloudy.
<Overview of Embodiment 2>

This embodiment shows the locking method of the umbrella fabric (0107). The center of the umbrella fabric has a hole with a large diameter of the center rod, and the center of the umbrella fabric is covered from above to pass through the upper end of the center rod, and is screwed into the upper skeleton deterrent and the upper portion of the upper handle It is locked between the detachable stone bumps.

<Embodiment 2 Tsuyasaki Installation>

The disassembleable and detachable umbrella of this patent is provided with Tsuyusaki (0111) and can be freely attached to and detached from the other end of the main bone. The tsuyusaki is attached to the umbrella fabric by a method such as pressure bonding. On the other hand, in the case of a normal long umbrella, Tsuyusaki is different in that it is sewn directly to the umbrella fabric. In the case of a folding umbrella, a hole is formed as a shape at the other end of the bone, and the umbrella fabric is often sewn directly into the hole.
<Overview of Embodiment 3>

In this embodiment, in addition to the description in claim 1 or 2, the center rod, the upper crossbone, the stone protrusion, the lower crosspiece, the main bone provided with the locking projection on the upper crosspiece side end, and the low crosspiece side end. It is an umbrella that can be disassembled and assembled, with the ribs with protrusions made of plastic.
<Embodiment 3 Material and Strength>

Since all the members are made of plastic, it is not necessary to separate them from metals, so that recycling can be more easily performed. About the strength point which is a concern when using a plastic member, it has a structure in which a sufficient strength can be obtained by structural ingenuity. In other words, the main bone is inserted from the upper side of the groove cut in the upper part, and the non-removable support portion (which is attached to the middle portion of the main bone) while being pivotably locked by the main bone removal inhibiting portion and the stone protrusion ( The ribs fixed to 0110) are inserted from the lower side of the groove cut on the lower side of the lower wheel (the side in the state where the upper wheel is set on the upper side), and are rotatably locked by the locking portion. Therefore, the strength of the plastic material is increased by using the elasticity of the plastic material, which is a method not found in existing umbrellas. Furthermore, the strength can be increased by using a fiber reinforced plastic as a material.
<Outline of Embodiment 4>

  In addition to being configured by any one or more of claims 1 to 3, this embodiment is made of polyvinyl chloride, POE (polyolefin elastomer or polyoxyethylene), APO (amorphous). High-quality polyolefin), EVA (ethylene vinyl acetate), and polyester.

The umbrella fabric is used to prevent rain, and materials suitable for it are used. And to prevent rain, various processing is applied to the umbrella fabric. The representative waterproofing is usually applied to the back of the fabric and does not allow water to pass through. There are many acrylic coatings, and there are also PU (= polyurethane) coating and silicon coating. The water repellent process is mainly applied to the surface of the fabric, and unlike the waterproof process, it is a process for splashing water. Processing raw materials are mainly fluorine-based. UV processing, which is slightly different from the previous waterproofing and water-repellent processing, is a process that raises the ultraviolet shielding rate, and it cuts UV with just the fabric, but UV processing improves the ultraviolet cut rate by several percent.
<Overview of Embodiment 5>

In addition to being described in any one of claims 1 to 4, this embodiment shows a disassembleable and detachable umbrella in which all or part of the plastic is a glass fiber reinforced plastic. Addresses concerns about product strength due to the use of plastic on the bones of the umbrella, and further improves the ease of handling by reducing the weight of the umbrella and improving the elasticity of the bone by using glass fiber reinforced plastic. Is intended to be Further, the portion using the glass fiber reinforced plastic may be only the middle rod, the main bone, and the bone receiving bone. The other part may be a normal plastic.
<Embodiment 5 material>

Glass fiber reinforced plastic is made by bundling glass fibers with a thickness of less than about 20 micrometers and infiltrating the resin between them. Light, strong, non-rusting, high electrical insulation, heat insulation, impact It has characteristics such as absorbability and is economical, so it is used in many applications.
<Summary of Embodiment 6>

In this embodiment, in addition to the form described in claim 5, a cover is put on the other end of the main bone so that the glass fiber reinforced plastic is not exposed. That is, the master bone is devised so that the glass fiber reinforced plastic is not exposed at both ends.
<Embodiment 6 material>

The glass fiber reinforced plastic is light in weight and rich in elasticity, and therefore satisfies the conditions for use as an umbrella member. On the other hand, the glass fiber reinforced plastic has a negative aspect that the glass fiber is exposed to cause injury. Since the glass-reinforced fiber plastic itself is easily damaged, the invisible fibers are exposed from the scratch, and the finger is often injured when touched. In the present invention, since there is a high possibility that the glass fiber reinforced plastic is exposed at the cut surfaces at both ends of the bone and the center rod, a device is provided to cover the glass fiber reinforced plastic so as not to be exposed. It leads to protection.
<Summary of Embodiment 7>

  In addition to being described in any one of claims 1 to 6, the present embodiment is a non-removable support portion in which a rotational connection portion between the parent bone and the receiving bone supports both bones in a non-removable manner. (FIG. 1). The non-removable support part is installed in the approximate center of the parent bone, and supports the bones that are connected to the bottom rail.

  FIG. 6 is a view of an umbrella without an umbrella fabric in a half-open state as seen from the side slightly above. It can be seen that the lower skull (0601) supports the bone, and the bone is also joined to the parent bone by the non-removable support portion (0602).

  FIG. 7 is a side view of a half-opened umbrella with no umbrella fabric placed on its bottom, opposite to FIG. The bottom pole (0701) is placed from the middle of the middle bar, and the handle (0702) and the bottom pole locking projection (0703) provided at the tip thereof are arranged. The bottom roller latching projection is made of a ring-shaped member, and the bottom surface of the circular tube through which the center rod of the bottom rail is inserted has a structure in which the ring-shaped protrusion is loosely engaged, so that the bottom rail is closed with the umbrella closed. Can be kept in a semi-fixed state.

  The non-detachable support portion not only makes the umbrella open and close smoothly, but also increases the durability of the umbrella against wind and the like when it is opened, thereby providing structural stability.

The non-releasable support portion, which is a joint portion between the master bone and the rib bone, is considered to be a portion to which the load is most applied when opening and closing, and is a portion that is easily damaged. In the present invention, it is structured to be made of plastic and is considered to be less damaged than metal. The non-detachable support portion is sometimes called a dowel.
<Embodiment 7 material>

Although the non-detachable support portion of the present invention is a resin material, other materials can be used for the non-detachable support portion. The non-detachable support portion made of metal is a dowel made of a metal material, and is a type that is attached later to the main bone and the bone, suitable for small-lot production, and relatively easy to repair. However, it is easy to rust because of metal, and when deburring is not performed well, for example, when bones of fiber reinforced plastic are combined, there is a weakness that the bones are easily broken. Fiber reinforced plastics and normal plastic non-removable support parts do not rust like metal non-releasable support parts, and appear to be integrated with the parent bone and ribs so that the appearance is refined. On the other hand, if the resin non-detachable support part itself is damaged, it is difficult to repair, and sometimes the entire umbrella bone or the main bone / support bone itself needs to be replaced.
<Summary of Embodiment 8>

In the present embodiment, each part is configured as in claims 1 to 7, in addition to a middle bar, a handle provided on the middle bar, a lower cross inserted through the middle bar, and a middle bar The first set with the main bone locking groove portion of the upper crossbone fixed to the top, the second set consisting of the main bone and the receiving bone, the third set of the main bone removal inhibiting portion constituting a part of the upper crosspiece, and a stone bump. It shows that it is an assembly umbrella kit consisting of the fourth group, the fifth group which is the umbrella fabric.
<Advantages of the eighth embodiment kit>

  This embodiment is a kit consisting of a total of 5 sets. By utilizing the fact that it is a kit, and being easy to disassemble and assemble, and designing the fifth set of umbrella fabrics, a custom-made umbrella can be easily created. By designing the first set of handles in the same way, a unified design can be obtained.

  For example, by simply sticking or drawing circular stickers of several colors only on umbrella fabric, it is possible to easily realize changes in design and shade, making it possible to create a custom-made umbrella like no other It is. If the handle is designed in the same way, the design will be even more uniform, but the impression will be very different because the color changes even with umbrella fabric alone.

  Also, because it is a kit, for example, when a part of the umbrella is broken for some reason, the consumer does not need to buy the whole again, but repairing the umbrella by replacing the broken part, the broken part pair There is an advantage that it becomes possible, and the cost is naturally low. Repairs can be easily performed because it is an umbrella that can be disassembled and assembled by ordinary people without the need for jigs or machines.

  Furthermore, from the viewpoint of waste, instead of throwing away the entire broken umbrella, it is possible to repair the umbrella by purchasing and exchanging one or several pairs. The number of members can be reduced to only one set or several sets. This leads to stopping environmental deterioration.

  From the standpoint of maintenance, it is clearly divided into 5 groups, so it is easy to select the parts to be discarded, and it can be replaced by purchasing the group, which contributes to ease of maintenance. It is.

  The handle is an umbrella handle and is also called a hand. In the present invention, the handle is firmly fixed to the middle bar by welding, bonding or other methods. The long umbrella cannot be attached unless the diameter of the center rod matches the diameter of the hole at hand. Moreover, since it is fixed with a strong adhesive, the hand cannot be easily replaced. However, the folding type is often screw type and can be replaced at hand.

  In the present invention, the locking protrusion of the bottom wheel is provided on the stone protrusion side of the handle, and the tip side portion of the bottom wheel on the side of the handle crosses the locking protrusion so that the bottom wheel can reversely move backward. The umbrella does not open due to the inability to do so.

The handle is made of plastic such as plastic, and original decoration can be applied by using several colored oily markers. When the handle color is white, drawing and coloring are easy. The marker is a writing instrument mainly for marking, and means a felt pen (marking pen) with a thick pen tip. Oil-based markers (oil-based inks) can be drawn on plastic and metal, and are excellent in quick-drying and water resistance after drying, and are widely used.
