Description

  The present invention relates to an umbrella that reversibly deploys an umbrella fabric constrained by a large number of main bones, and for example, relates to an umbrella that is effective for use in a jump-type umbrella that performs an urging of an umbrella with an elastic repulsive force of a spring.

  As is well known, the umbrella is composed of an upper croquette fixed to the tip of the middle rod, a large number of main bones whose base end is hinged to the upper crocodile and reversibly deployed radially, and a lower part of the upper crocodile. And a lower bone that is slidably fitted to the middle rod, a base end hinged to the lower rocker, and a distal end hinged to an intermediate position of the parent bone. The master bone is reversibly deployed together with the umbrella fabric by the vertical movement of the lower lokuro (see Non-Patent Document 1, for example).

Further, in the umbrella, a second lower rocker is installed below the lower rocker (in this case, also referred to as the middle rocker), and is slidably fitted to the middle bar so as to be detached from the upper moving locking repellent. At the same time, the pulling bones whose both ends are hinged to the tip of the stem of the rib and the second lower rocker, and between the lower rocker (middle rocker) and the second lower rocker in the extending direction. If a spring that is urged against pressure is provided, an umbrella that is automatically urged to open by the elastic repulsion of the spring when the second lower locomotive is released from the repelling by the repellency, so-called A jump-type umbrella can be formed (see, for example, Patent Document 1).

  In the above-described umbrella, the larger the number of master bones that restrain the umbrella fabric, the better and more stable the shape of the opened umbrella, and the stronger the umbrella when it is opened. For this reason, the more expensive umbrellas, the greater the number of parent bones. In recent years, as for umbrellas, low-cost products that omit the number of skeletons have become popular, while the trend toward high-quality umbrellas with a large number of skeletons has also increased.

  However, when the number of main bones is increased, the number of bones that support and open and close each parent bone is also required by the number of the parent bones, which increases the weight of the umbrella. In addition, since the receiving bone is hingedly connected to each parent bone, if the number of parent bones is increased, the number of parts and the number of assembling steps are increased and the cost is increased. In addition, when the umbrella is closed, a rib is interposed between the main bone and the middle rod, so if there are many ribs, the umbrella cannot be closed thinly, which may cause inconvenience when carrying and storing when not in use. become.

  The present invention has been made in view of the problems as described above, and its object is to obtain a good and stable umbrella opening state, enable cost reduction by reducing the number of parts, and further close. It is to provide an umbrella that can be reduced in diameter (slimmed).

  The operations / effects other than the above will be clarified in the description of the present specification and the accompanying drawings.

  1 and 2 show a preferred embodiment of an umbrella according to the present invention. FIG. 1 shows a state in which the umbrella according to the present invention is viewed from the side, and FIG. 2 shows the AA arrow plane of FIG.

  The umbrella shown in the figure is a so-called jump-type umbrella, and includes, as its main components, an intermediate rod 10, an upper rocker 21, a lower rocker (middle rocker) 31, a second lower rocker 41, a main bone 50, a bone receiving bone. 60, a pulling fulcrum 70, a spring 45, and the like.

  The center rod 10 has a stone protrusion 11 at its upper end and a hand 12 at its lower end. Further, an upward movement locking repelling 13 for releasably locking the second lower roller 22 to the closed position is attached. The locking by the repellent 13 is released by the pressing operation of the button 14 located immediately above the hand 12.

  The upper rocker 21 is fixed to the upper end portion of the middle rod 10. A large number (16 in the illustrated embodiment) of base bones 50 for restraining the umbrella fabric 55 are hinged to the upper roll 21. Each master bone 50 has a dowel fitting 53 (enlarged portion in FIG. 2) for hinge connection attached to a base end portion thereof, and a tip 51 attached to a distal end portion thereof.

  The lower rocker 31 is slidably fitted to the middle rod 10 below the upper rocker 21. A base end portion of the receiving bone 60 is hinged to the lower rocker 31. The base end portion of the receiving bone 60 is hinge-connected to the lower rocker 31, and the distal end portion thereof is hinge-connected to a middle position of the main bone 50 via a dowel fitting 52.

  When the receiving bone 60 is opened and closed by the vertical movement of the lower rocker 31, the parent bone 60 is opened and closed in conjunction with the operation of the receiving bone 61. Thereby, the main bone 50 can be reversibly deployed together with the umbrella fabric 55.

  In the jump-type umbrella, the above-described lower rock 31 is also referred to as “middle rock”, but here it is referred to as “lower rock” in order to correspond to the lower rock of the non-jump-type umbrella that is manually opened.

  A second lower rocker 41 is installed below the lower rocker 31. The second lower roller 41 is slidably fitted to the middle bar 10 and is also detachably locked to the upper movement locking repellent 13 at the lower part of the middle bar 10.

  The pulling support frame 70 is bridged between the second lower roller 41 and the intermediate position of the receiving bone 60. One end of the pulling support frame 70 is hinge-connected to the second lower rocker 41 and the other end is hinge-connected to an intermediate position of the receiving bone 60.

  Along with this, a coil spring 45 is provided for elastically biasing the lower part 31 and the second lower part 41 in the extending direction. As a result, when the second lower roller 41 is released from being locked by the repellent 13, the umbrella is biased by the elastic repulsive force of the spring 45.

  Here, in the umbrella according to the present invention, in addition to the above-described configuration, as shown in an enlarged view of the main part in FIG. 2, the bone receiving 60 is composed of a single rod-shaped trunk 61 and the tip of the trunk 61. And a pair of branch portions 62 and 62 that can be expanded by elastic bending.

  3 and 4 show an embodiment of the above-mentioned receiving bone 60 and the pulling support bone 70. As shown in the figure, the receiving bone 60 is a single part in which a trunk portion 61 and branch portions 62 and 62 are formed as an integral resin molded product. A shaft hole 63 is provided for hinge connection. Further, dowel fittings 64 and 64 for making range connection with the ribs 60 are attached to the ends of the branch portions 62 and 62, respectively. A hook portion 65 is integrally formed at the distal end portion of the trunk portion 61 so that the hook fitting 72 formed at the distal end portion of the pulling support frame 70 is rotatably locked.

  The pulling fulcrum 70 is made of a metal wire material (for example, steel wire), one end of which is a hook portion 71 for hinge connection with the second lower rocker 41 (see FIG. 5), and the other end. The hook metal parts 72 for hinged connection with the ribs 60 are formed by bending.

  Furthermore, in the case of this embodiment, the pulling support frame 70 is formed by folding the metal wire material in the middle of its entire length to form a parallel bilateral bone, and the U-shaped portion of the folded portion is the hook metal part 72. (FIG. 3).

  FIG. 5 shows an enlarged view of the main part of the jump-type umbrella described above. In the figure, a sleeve 22 is integrally provided under the upper rocker 21, but this sleeve 22 regulates the upper limit position of a lower rocker (medium rocker) 31 that is elastically biased upward by a coil spring 45. . As a result, a certain opening shape can be obtained. A sleeve 32 is integrally provided below the lower roller 31, and a coil spring 45 is loosely fitted to the sleeve 32. The sleeve 32 has a guide function that makes the expansion and contraction of the coil spring 4 stable and smooth.

  FIG. 6 shows another embodiment of the pulling span 70. Since the main load applied to the pulling support frame 70 is the pulling load by the spring 45, as long as it can withstand the pulling load, as shown in the figure, both ends of one metal wire material are bent. Can be used.

  In the umbrella described above, each of the ribs 60 supports the two main bones 50, so even if the number of the main bones 50 is increased in order to improve the shape of the umbrella, the number of the ribs 60 is half of that. Just do it. As a result, a good and stable opening state can be obtained, the cost can be reduced by reducing the number of parts, and the diameter can be reduced (slimmed) when closed.

  In addition, as shown in FIG. 2, the trunk portion 61 of the bone support 60 is positioned between the master bone 50 and the master bone 50, and the pair of branch portions 62 and 62 of the bone support 60 are positioned on both sides of the stem portion 61. When the umbrella is closed, the hinges are connected to the main bones 50 and 50, respectively, and the branch portions 62 and 62 are elastically bent and expanded by approximately equal amounts when the main bones 50 and 50 are deployed. The receiving bone 60 can be placed between the parent bones 50 and 50.

  That is, it is possible to avoid the parent bone 50 from overlapping the receiving bone 60 when the umbrella is closed. As a result, the diameter of the umbrella when closed can be further reduced, and the convenience of carrying and storing when not in use is further improved.

  Since the trunk portion 61 and the branch portions 62 and 62 are formed of an integral resin molded product, the bone receiving portion 60 can further increase the mass productivity and contribute to the cost reduction.

  Moreover, although the umbrella of the said embodiment is comprised as a jump-type umbrella which uses three types of bones, the main bone 50, the receiving frame 60, and the tension | pulling support frame 70, according to this invention, the number of the tension support frames 70 is the number. As with the ribs 60, it can be reduced to half of the parent bone 50.

  Therefore, the present invention is effective even when applied to a non-jump type umbrella in which the opening operation is manually performed. However, in the jump umbrella, a pulling fulcrum 70 which is an essential part for performing the function of the jump type umbrella. This makes it possible to further reduce the cost and weight of the jump umbrella.

  Moreover, in the said embodiment, although the metal wire material is used for the tension | tensile_strength support frame 70, the metal wire material is folded in the middle of the full length, a parallel double-bone is formed, and the said U-shaped part of the folding | returning part is above By forming the hook metal part 72, a high strength support frame 70 can be formed even with a relatively thin wire material. As a result, an increase in the diameter of the closed umbrella due to the support frame 70 is avoided, and a jump-type umbrella can be slimmed when closed.

  As mentioned above, although this invention was demonstrated based on the typical embodiment, this invention can have various aspects other than having mentioned above. For example, the present invention can also be suitably applied to a non-jump-type umbrella that manually performs an opening operation or a folding umbrella that uses an extendable center rod.

  A good and stable open state of the umbrella can be obtained, the cost can be reduced by reducing the number of parts, and an umbrella that can be reduced in diameter when closed (slim) can be obtained.
