Description

  The present invention relates to an umbrella cloth fixture used for fixing an umbrella cloth stretched around a master bone to an intermediate portion of the master bone.

  Conventionally, as shown in FIG. 10, the umbrella has a plurality of attachments that can be opened and closed by pivotally attaching the base end portion to the outer periphery of the upper rocker 4 arranged at the tip of the central shaft 3 having the hand 2 at the base end. In general, an umbrella cloth 7 is stretched around the main bone 5 via a tip 6.

  Further, since the main bone 5 is long, it is not possible to integrate the main bone 5 and the umbrella cloth 7 by simply stretching the umbrella cloth 7 on the main bone 5 using the tip 6. Since it is necessary to prevent the umbrella cloth 7 from being detached due to a pressing force generated by wind or the like, a means for fixing the umbrella cloth 7 also in the middle part of the main bone 5 is taken.

  By the way, since the umbrella cloth 7 is generally made of cloth, a means for sewing using the thread 9 when fixing the umbrella cloth 7 in the middle part of the main bone 5 is general. Since it takes time and effort even in the production process, it is easy to install, and recently, an umbrella that can be removed by considering separation, recycling and replacement at the time of disposal is desired. As a means for fixing the intermediate portion of the main bone 5 and the umbrella cloth 7 together with the possible tip 6, a means that can be removed without using sewing has been adopted.

  As a means for removably fixing the umbrella cloth 7 to the main bone 5 at the intermediate part of the main bone 5, for example, a belt-shaped umbrella cloth fixing member 91a as shown in FIG. 11 is wound and fixed by a hook 92a. Umbrella cloth fixing tool 93a (Japanese Utility Model Publication No. 31-2771) is known, but there is a problem that the hook 92a has to be manually fitted when mounting and there is a problem in mass production, and the umbrella cloth is fixed. Since the master bone 5 is directly held by the member 91a, there is no buffering property in the fixing portion, and therefore the problem is that the umbrella cloth 7a and the joint portion between the umbrella cloth 7a and the umbrella cloth fixing tool 93a are easily damaged when wind is entangled from the inside. There is.

  Further, as shown in FIG. 12, an umbrella cloth fixing member 96b (utility model registration) in which a fixing operation is simplified by winding a belt-shaped umbrella cloth fixing member 94b instead of the hook and fastening it with a hook-and-loop fastener 95b. No. 3150807 publication), but it is necessary to install a relatively expensive hook-and-loop fastener 95b for each parent bone, so that there is a problem that the material cost increases and it takes time and effort for attachment. Therefore, there is a problem that the umbrella cloth 7b and the joint part between the umbrella cloth 7b and the umbrella cloth fixture 95b are easily damaged when the wind is entangled from the inside.

  Furthermore, an umbrella cloth fixing tool 98c (Japanese Patent Laid-Open No. 2002-238625) for fitting a C-shaped fitting portion 97c formed of, for example, an elastic resin or an elastic wire as shown in FIG. It is known that this umbrella cloth fixing tool 98c can be fixed by a simple operation of simply inserting the main bone 5c into the C-shaped space, and is easy to attach and detach the main bone 5c and the umbrella cloth 7c for recycling and replacement of the umbrella cloth. Furthermore, when the wind is rolled into the umbrella cloth 7c from the inside during use, and the umbrella cloth 7c is pressed from the inside to the outside, the fitting with the main bone 5c is released and the main bone 5c by wind pressure is released. And an excellent advantage of preventing damage to the umbrella cloth 7c.

  However, an umbrella fixing fixture 97c for fitting the conventional C-shaped fitting portion 97c to the main bone 5c so that it can be inserted / removed can be secured to the umbrella cloth 7c by directly sewing the base portion or a belt-like piece wound around the base portion. In order to avoid this, both of them are attached by means of welding, rivets, etc., both of which have a small contact area of the fixing part to the umbrella cloth 7c, and are easily damaged by the wind force at the time of use, and the tensile force is concentrated directly on the fixing part. In this case, the connection strength between the main bone 5c and the C-shaped fitting portion 97c must be set to be weak, and the main bone 5c and the umbrella cloth 7c must be easily detached even when the wind has a low pressing force. . Moreover, the same thing can be said about what winds the belt-shaped piece, and in addition, since it slips out of the C-shaped free end portion, it is necessary to devise a fixing means for the belt-shaped piece, resulting in a complicated configuration. There is also a problem that the work process becomes complicated and is not suitable for mass production.

  Recently, umbrellas called polyolefin umbrellas made of transparent polyolefin / elastomer (POE) or semi-transparent synthetic resin made of ethylene / vinyl acetate copolymer (EVA resin) are often used as umbrella fabrics. In the case of the umbrella, it is difficult to use the sewing means because the needle hole is widened, and in the case of rivets, there is a problem that a dedicated machine is required and skill is required. Therefore, since the vinyl umbrella is formed by joining a plurality of pieces of cloth having a substantially triangular shape to each other by a fixing means such as sewing or welding at the joining margin, as shown in FIG. Japanese Patent Application Laid-Open No. 2008-125957 discloses that an umbrella cloth fixture 99d made of a loop-shaped piece is overlapped and welded to a joining allowance 72d at the time of joining the umbrella cloth 7d.

  This fixing means can be attached to the umbrella fixing tool 99d by heat welding, so it is lighter and simpler than other locking methods such as sewing and rivets, and the site is not confused due to unfamiliarity in the manufacturing process. Therefore, it is easy and quick to manufacture, and is suitable for mass production.

  However, as described above, the portion that locks the main bone 5d and the umbrella cloth 7d (the tip is relatively strong) lacks robustness, and is pulled by the wind received by the umbrella cloth 7d, and the impact is fixed to the umbrella. The same force acts directly on the cloth fixing tool 99d, and heat welding has a weaker locking force than the sewing with thread, and is easily detached. Once peeled off, it is difficult for the consumer to repair and easy to manufacture. On the other hand, since the umbrella cloth fixing tool 99d has a loop shape, there is also a problem that it is difficult to extract the main bone 5d in a state where it can be reused.
