Description

  The present invention relates to an umbrella such as an umbrella or a parasol, and more particularly to an umbrella using a composite material such as carbon fiber or glass fiber for any or all of a rib, a receiving bone, and a support.

  The western umbrella is a column with an upper wheel fixed to the upper end and a gripping part fixed to the lower end, a lifting and lowering wheel that moves in the longitudinal direction of the column, a rib on one end of which is supported by the upper wheel, and one end in the middle of the rib. The supporting part is rotatably supported at the part and the other end is provided with a supporting bone supported by the elevating wheel. The up-and-down moving of the elevating wheel in the longitudinal direction of the support column is transmitted to the rib through the bone, thereby being attached to the rib. Open and close umbrella cloth.

  An engaging member (hereinafter referred to as a cissing) is exposed to the support column from two upper and lower openings via elastic force so as to be able to retract to the inside of the support column. And stops at the upper or lower limit of the movement range.

  When opening the umbrella cloth in the closed umbrella state, press the lower repelling member engaged with the elevating wheel on the inside of the column to release the engagement state between the lower repelling member and the elevating wheel, Raise the wheel. When closing the umbrella cloth in the opened state, the upper repelling member engaged with the elevating wheel is pressed to the inside of the column to release the engagement between the upper repelling member and the elevating wheel, Lower the wheel.

  Excessive wind pressure may act on the umbrella cloth in the open state, and the wind pressure applied to the umbrella cloth in the open state is supported by the rib, the receiving bone, and the support. Therefore, the ribs, the receiving bones, and the struts need to have a sufficient wind pressure resistance function, and many of them are formed of a metal material such as iron. However, if the ribs, receiving bones, and columns are made of a metal material having sufficient strength, such as iron, the overall weight of the umbrella increases, and portability and operability deteriorate.

  In addition, for the purpose of reducing the weight of the umbrella, some or all of the ribs, receiving bones and struts were made of an aluminum alloy, but aluminum alloys are lighter than iron and the like, but have insufficient strength. In this case, deformation and breakage easily occur, and a sufficient wind pressure resistance function cannot be obtained.

Therefore, a western umbrella has been developed in which any or all of a rib, a receiving bone, and a support are formed by heating and molding a composite material such as carbon fiber or glass fiber (see, for example, Patent Document 1). These composite materials are sufficiently lightweight and have equal or higher strength than metal materials, and impair the wind resistance function by using composite materials for any or all of the ribs, the receiving bones, and the columns. The umbrella can be made lighter without the need.
JP-A-8-322620

  However, it is necessary to form a support part for supporting the receiving bone in the middle part of the rib of the western umbrella, and it is necessary to form an opening for exposing the upper and lower cissing on the pillar, and use of the western umbrella In some cases, the ribs, receiving bones or struts may be damaged.However, if a composite material such as carbon fiber or glass fiber is partially lost in the surface fiber tissue, a part of the fiber tissue will be removed from the missing part. It is easy to peel along the fiber direction, and the strength is significantly reduced at that portion. For this reason, on the surface of the rib, receiving bone or strut made of the composite material, the strength of the processed part such as the support part and the opening part and the part damaged during use is significantly reduced, and a sufficient wind pressure resistance function is obtained. There is a problem that cannot be secured.

  Further, since carbon fibers are black and glass fibers are non-reflective materials for light, these materials are inferior in decorativeness. Therefore, it is conceivable to form a glossy metal layer on the outer layer of carbon fiber or glass fiber by electrode treatment.However, since carbon fiber or glass fiber has no conductivity, the outer layer of carbon fiber or glass fiber is firstly formed. It is conceivable to form a metal layer on the outer layer of the chemical nickel layer by electrode treatment after applying and drying the chemical nickel liquid.

  However, the bonding strength between the carbon fiber or glass fiber and the chemical nickel layer is very weak compared to the bonding strength due to the electrode treatment between the chemical nickel layer and the metal layer. In the above-described configuration in which a glossy metal layer is formed on the outer layer, when the umbrella cloth in the opened state is closed, the umbrella cloth is wound around, and the metal layer is peeled off together with the chemical nickel layer. In addition, not only the decorativeness of the ribs and the receiving bones, but also the umbrella cloth may be stained.

  The purpose of this invention is to form a plurality of metal layers on any or all surfaces of the ribs, receiving bones, or columns formed by heating and molding a composite material, and to form a metal layer having excellent gloss on the outermost layer. An object of the present invention is to provide a western umbrella which is excellent in decorativeness, is lightweight, and can prevent a decrease in strength due to peeling of a fibrous tissue by forming the umbrella.

  The umbrella of this invention is configured as follows to solve the above-mentioned problem.

(1) One end of a rib is rotatably cantilevered on an upper wheel fixed to the upper end of a support, and the other end is raised and lowered on the other end of a receiving bone rotatably supported by a support at an intermediate portion of the rib. The elevator is rotatably supported on the wheel, and the elevating wheel is freely movable in the longitudinal direction of the column within a range that engages with each of the locking members exposed to the outside via elastic force from two places above and below the column, In a western umbrella that opens and closes an umbrella cloth by transmitting the operation of the raising and lowering wheel to the rib through the receiving bone,

  Since a glossy chrome or gold layer is formed on the outermost layer of the rib, a rib having excellent decorativeness is formed. In addition, the ribs are reinforced by the plurality of metal layers, and the fibrous structure of the composite material is not exposed in the portion reinforced by the plurality of metal layers, which may cause peeling or fluffing of a part of the fibrous structure. As a result, the wind resistance of the ribs is maintained and the safety of the user is ensured. Furthermore, the use of a composite material is very light.

In addition, the ribs are reinforced by the plurality of metal layers, and the fibrous structure of the composite material is not exposed in the portion reinforced by the plurality of metal layers, which may cause peeling or fluffing of a part of the fibrous structure. As a result, the wind resistance of the ribs is maintained and the safety of the user is ensured. Furthermore, the use of a composite material is very light.

And a raising and lowering wheel 40 rotatably supporting the other end. At the upper and lower portions of the support 10, repelling members 14 and 15 are exposed to the outside so as to be able to retreat into the support member 10 through elastic force, and the raising and lowering wheel 40 is engaged with the upper and lower repelling members 14 and 15, respectively. It can be moved up and down within the range.

  In FIG. 1, only a single rib 20 and a receiving bone 30 are shown for easy understanding.

  When the umbrella cloth attached to the plurality of ribs 20 is opened from the closed state, the lower cissing 15 engaged with the raising and lowering wheel 40 is pressed against the inner side of the column 10 and the raising and lowering wheel 40 is raised. . The lifting operation of the lifting wheel 40 is transmitted to the rib 20 through the lifting wheel 40 and the receiving bone 30 whose both ends are supported by the rib 20, and the rib 20 is opened at the one end supported by the upper wheel 12 as a fulcrum. Is rotated in the direction away from the column 10, and the umbrella cloth attached to the rib 20 is expanded. The elevating wheel 40 stops lifting at a position where it engages with the upper repelling member 14, and maintains the open state by engagement with the upper repelling member 14.

  When closing the umbrella cloth from the open state, the upper and lower revolving wheel 40 is lowered while pressing the upper repelling member 14 engaged with the raising and lowering wheel 40 against the inside of the column 10. The lowering movement of the raising and lowering wheel 40 is transmitted to the rib 20 via the receiving bone 30, and the rib 20 rotates around the one end pivotally supported by the upper wheel 12 in the direction in which the dew tip approaches the column 10, and the rib 20 The umbrella cloth stuck on is folded.

  2: is a figure which shows the manufacturing process of the rib 20, the receiving bone 30, and the support | pillar 10 of the western umbrella 1 shown in FIG. The support 10, the rib 20, and the receiving bone 30 form a hollow rod-shaped or wire-shaped base material 20a (see FIG. 3) by, for example, heating and molding a composite material such as carbon fiber, and the surface of the base material 20a. It is manufactured by forming a chemical nickel (reduced nickel metal) layer 20b, a copper layer 20c, a nickel layer 20d, a gold layer 20e, and a fluororesin layer 20f in this order. In addition, in the case of the support | pillar 10, after forming the opening part which the cissing 14 and 15 are exposed in the base material 20a, it manufactures by forming each layer 20b-20f.

  In the process of forming each of the layers 20b to 20f on the surface of the base material 20a, first, the surface of the base material 20a is subjected to an electrode treatment such as a positive or negative electrode treatment, and then the surface of the base material 20a is corroded by a chemical agent. After the surface of the substrate 20a is rinsed with another chemical agent, the catalyst is subjected to a crosslinking action. Further, chemical nickel is applied to the surface of the base material 20a and dried to form a chemical nickel layer 20b as a conductive layer. Further, the copper layer 20c is formed by attaching copper powder to the surface of the chemical nickel layer 20b by electroplating using another electrode. Further, a nickel layer 20d is formed by depositing nickel powder on the surface of the copper layer 20c by electroplating, and a gold layer 20e is formed by depositing gold powder on the surface of the nickel layer 20d by electroplating. I do. Further, a substantially transparent fluororesin layer 20f such as Teflon (registered trademark) is formed on the surface of the gold layer 20e. In this manner, tight layers 20b to 20f of metal or the like are formed on the surface of the base material 20a.

  In order to form the gold layer 20e, it is necessary to form a nickel layer 20d as a base layer, and to perform electroplating on the surface of the base material 20a, it is necessary to form a chemical nickel layer 20b as a conductive layer. is there. However, since the nickel layer 20d cannot be formed directly on the surface of the chemical nickel layer 20b, the copper layer 20c is first formed on the surface of the chemical nickel layer 20b by electroplating, and the surface of the copper layer 20c is further electroplated. By forming the nickel layer 20d, the gold layer 20e can be formed.

  In the above-described manufacturing process, the roughening treatment of the surface of the base material 20a is not limited to the roughening treatment by corrosion using a chemical agent, and may be a method of rubbing the surface of the base material 20a with a file. Further, in the stage of the roughening treatment of the surface of the base material 20a, it is preferable that deburring is performed on an opening or the like provided on the base material 20a of the support post 10 and exposing the cissing 14, 15.

  By the above-described manufacturing process, not only can the pillar 10, the rib 20 and the receiving bone 30 having sufficient toughness and wind pressure resistance be manufactured, but also the surface of the base material 20a made of a composite material has excellent metallic luster. Thus, it is possible to manufacture the pillar 10, the rib 20 and the receiving bone 30 having excellent decorativeness.

  The thickness and density of each of the layers 20b to 20f can be adjusted by the concentration of the chemical agent used in the above-described manufacturing process and the processing time.

  FIG. 3 is a cross-sectional view showing a part of a rib forming a part of the western umbrella shown in FIG. By the manufacturing process as described above, the rib 20 is formed by forming a chemical nickel layer 20b formed as a conductive layer on the outer layer of a base material 20a formed by heating a composite material such as carbon fiber or glass fiber into a wire, and a chemical nickel layer 20b. A copper layer 20c having a thickness of about 0.006 mm formed on the outer layer of the above, a nickel layer 20d having a thickness of about 0.003 mm formed on the outer layer of the copper layer 20c, and a copper layer 20d formed on the outer layer of the nickel layer 20d. A gold layer 20e having a thickness of about 0.002 mm and a fluororesin layer 20f having a thickness of about 0.003 mm formed on an outer layer of the gold layer 20e are provided.

  The receiving bone 30 is formed on the outer layer of a chemical nickel layer formed as a conductive layer on the outer layer of a base material obtained by heating and molding a composite material such as carbon fiber or glass fiber into a wire, and the outer layer of the chemical nickel layer, similarly to the rib 20. Copper layer having a thickness of about 0.006 mm, a nickel layer having a thickness of about 0.003 mm formed on the outer layer of the copper layer, and a copper layer having a thickness of about 0.002 mm formed on the outer layer of the nickel layer. A gold layer and a fluororesin layer having a thickness of about 0.003 mm formed on an outer layer of the gold layer are provided.

  The column 10 has a chemical nickel layer formed as a conductive layer on an outer layer of a base material formed by heating and molding a composite material such as carbon fiber or glass fiber into a hollow rod material, and a thickness formed on an outer layer of the chemical nickel layer. A copper layer having a thickness of about 0.006 mm, a nickel layer having a thickness of about 0.003 mm formed on the outer layer of the copper layer, a gold layer having a thickness of about 0.002 mm formed on the outer layer of the nickel layer, A fluororesin layer having a thickness of about 0.003 mm formed on an outer layer of the layer.

  Since the gold layer 20e having excellent gloss is formed on each of the visible layers of the rib 20, the receiving bone 30, and the pillar 10, the decorativeness of the umbrella 1 is enhanced. Further, since the fluororesin layer 20f, which is a substantially transparent protective resin layer, is formed on the outer layer of the gold layer 20e, the metal layers 20b to 20e such as the gold layer 20e can be separated without impairing the decorativeness of the gold layer 20e. Is prevented. Further, since the fluororesin layer 20f is formed on all outermost layers of the rib 20, the receiving bone 30 and the strut 10 including the tip and the dowels, the rib 20, the receiving bone 30 and the strut 10 are made water-repellent. Excellent, rust is prevented from being generated in the respective metal parts of the rib 20, the receiving bone 30, and the support post 10.

  In addition, since the fluororesin layer is formed on the outermost layer of the column 10, the self-lubricating property of the surface of the column 10 is improved, the slipperiness of the raising and lowering wheel 40 during the raising and lowering operation is improved, and the wear resistance is improved. You.

  In addition, since a plurality of layers of metal or the like are formed on the outer layer of the base material 20a, the composite material is not exposed on the surfaces of the rib 20, the receiving bone 30, and the column 10. For this reason, the fiber structure of the composite material located on the outermost layer of the base material 20a is bonded to each other via a metal material such as the copper layer 20c, and the base material 20a may be directly damaged during use of the umbrella 1. In addition, a part of the fibrous tissue is not easily peeled along the fiber direction in the wound portion on each surface of the rib 20, the receiving bone 30, and the strut 10, and the rib 20, the receiving bone 30, and the strut 10 Strength is guaranteed. Furthermore, the ends of the fibrous tissue do not become fuzzy at the wounds on the surfaces of the ribs 20, the receiving bones 30 and the struts 10, thereby damaging the fingers of the user who accidentally touched the wounds. There is no.

  Instead of the gold layer 20e, a chromium layer may be similarly formed on the surface of the nickel layer 20d by electroplating. The outermost layer of each of the rib 20, the receiving bone 30, and the support 10 is not limited to the formation of the fluororesin layer 20f such as Teflon (registered trademark), but may be a layer of a transparent varnish or a substantially transparent lacquer. It may be formed. Further, in each of the rib 20, the receiving bone 30, and the strut 10, a transparent varnish or a substantially transparent lacquer layer is formed on the outer layer of the gold layer 20e or the chrome layer, and a fluororesin layer 20f is formed on the outer layer. Is also good.

  Generally, one end of the receiving bone 30 is pivotally supported at an intermediate portion of the rib 20 via a supporting member called a dowel. This support member is usually formed by molding a flat metal plate into a shape having a substantially U-shaped cross section and partially projecting a bearing portion, and is externally fitted to an intermediate portion of the rib. One end of the receiving bone 30 is rotatably supported by a bearing portion of the support member via an eyelet or a pin.

  However, when the support member made of a metal material is externally fitted to the rib 20 made of a composite material such as carbon fiber, the rib 20 is easily broken at a portion in contact with both ends of the support member in the longitudinal direction of the rib 20.

  Then, the cylindrical reinforcement member covering both ends of the support member and the range including the portions contacting with both ends of the support member is further externally fitted. The reinforcing member reinforces the contact portion of the rib 20 with the support member, and can prevent damage to the rib 20 at this portion. By forming the reinforcing member with a transparent resin, the rib can be reinforced without impairing the decorativeness of the rib 20.

It is a figure showing the composition of the western umbrella concerning the embodiment of this invention. FIG. 2 is a view showing a manufacturing process of a rib, a receiving bone, and a support of the western umbrella shown in FIG. 1. FIG. 2 is a sectional view showing a part of a rib forming a part of the western umbrella shown in FIG. 1.
