Description

[Technical Field]

[0001] The present invention relates to a cover that can protect the shoulder belts (3) of backpacks, sacks, and back-mounted industrial machines (1) from rain, snow, mud, dust, and chemicals. [Background technology]

[0002] Traditionally, products worn on the back by humans have been widely used when hiking, commuting to work or school, or operating industrial machinery. Most of these products are typically made of cloth or leather and have a main body with internal storage space and a pair of shoulder straps (3) sewn to the top and bottom of the main body. The most common of these are backpacks, sacks, and backpack-style industrial machinery (1). A backpack body cover (2) as shown in FIG. 4 has been known as a cover that is attached to a backpack. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-253318 [Patent Document 2] Japanese Patent Application Laid-Open No. 2003-038224 Summary of the Invention [Problem to be solved by the invention]

[0004] Rain gear and covers to protect the main body of backpacks, sacks, and other backpack-type industrial machinery (1) are widely available. However, to protect the shoulder straps from rain, snow, mud, dust, and chemicals, it was necessary to use an umbrella or raincoat to protect the entire body, or to place the backpack, sack, or backpack-type industrial machinery itself in a waterproof bag.

[0005] For example, the backpack cover disclosed in Patent Document 1 covers both the main body and shoulder straps. In addition to Patent Document 1, there are other products that protect the backpack including the shoulder straps in addition to protecting the head and shoulders of the body, and products that protect the backpack including the shoulders and shoulder straps of the body. These products are one-piece covers that cover both the body and the backpack including the shoulder straps, so they have the problem of needing to be put on and taken off at the same time.

[0006] In addition, the shoulder belt cover disclosed in Patent Document 2 has the function of softening the impact of the shoulder belt on the part of the shoulder that touches the user's shoulder and preventing it from slipping, but it has little ability to protect the shoulder belt from external factors. [Means for solving the problem]

[0007] To solve the above problem, a backpack body cover (2) that covers only the existing body of a backpack / backpack-type industrial machine (1) is used for the main body, as shown in Figure 4, and a shoulder belt cover (16) according to the present invention is used for the shoulder belt (3). The shoulder belt cover (16) is characterized by having a tubular section made of snaps, buttons, and thread so that the shoulder belt (3) of the backpack / backpack-type industrial machine (1) can be covered with water-repellent and waterproof fabric, a fastening mechanism for fastening the cover to the upper part of the shoulder belt (4) that contacts the main body of the backpack / backpack-type industrial machine (1), and an outlet for discharging rain, snow, mud, dust, and chemicals that run down the cover. By separating the protective covers for the main body and shoulder belt sections, protection is provided only when needed, eliminating the need to cover unnecessary sections.

[0008] Furthermore, in the case of backpack-type industrial machinery, the main body is often made of plastic or painted metal, so the area that is most susceptible to the accumulation of liquids and dirt is the shoulder belt 3. By using the shoulder belt cover 16 according to the present invention, the shoulder belt 3 can be protected from rain, snow, mud, dust, and chemicals.

[0009] The shoulder belt cover (16) of the present invention can be stored compactly by using the fixing mechanism for fixing the cover when storing it, or by using a new storage device (15) made of water-repellent and waterproof fabric with snaps and buttons. It can also be stored compactly in a part of the shoulder belt (3) so that it can be used whenever needed. [Effects of the Invention]

[0010] The present invention can be used to cover the shoulder straps (3) of backpacks and other industrial equipment (1) to protect them from rain, snow, mud, dust, and chemicals. The cover is easy to put on and take off, and can be folded up when not in use, making it easy to carry, store, and prepare for use.

[0011] In addition, since there is no need to use a cover that completely covers the body and the backpack / pack / backpack-type industrial machine (1), it becomes easier to move around.

[0012] The present invention physically covers the shoulder belt (3), and therefore provides a higher protection effect for the shoulder belt (3) than when the shoulder belt (3) is covered with a waterproof spray. [Brief explanation of the drawings]

[Figure 2] 1 is a perspective view showing the vicinity of the fastener when a shoulder belt cover (16) according to one embodiment of the present invention is attached to the left shoulder belt of a backpack. [Figure 3] FIG. 2 is a plan view of the shoulder belt cover (16) according to the embodiment. [Figure 4] This is a perspective view of a backpack / pack / backpack-type industrial machine (1) using an existing backpack / pack body cover (2). DETAILED DESCRIPTION OF THE INVENTION [Example]

[0014] Hereinafter, an embodiment of the shoulder belt cover (16) of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing a backpack-type industrial machine (1) to which a shoulder belt cover (16) of this embodiment is attached.

[0015] As shown in Fig. 1, the shoulder belt cover (16) of this embodiment protects a pair of left and right shoulder belts (3) attached to an object carried on a backpack or backpack-type industrial machine (1) from rain, snow, mud, dust, and chemicals. In the following embodiments, the shoulder belt cover (16) will be described using the example of being attached to a backpack or backpack as shown in Fig. 1, but it may also be used for backpack-type grass cutters, sprayers, dust collectors, transport tools, and beer servers.

[0016] Next, the material of the shoulder belt cover (16) will be described. The shoulder belt cover (16) of this embodiment is made of water-repellent polyester fabric to protect the shoulder belt (3) from external factors. Other water-repellent or waterproof materials such as nylon and vinyl may also be used. Furthermore, the lining of the shoulder belt cover (16) may be lined with cloth or rubber to reduce the burden on the user's shoulders and prevent the cover from slipping down due to friction with the shoulder belt (3).

[0017] Next, the shoulder belt cover main part (7) of the shoulder belt cover (16) will be described with reference to FIG. The shoulder belt cover main part (7) of the shoulder belt cover (16) is formed to cover the shoulder belt (3) in a cylindrical shape. To form the cylindrical shape, the long edges of the shoulder belt cover main part (7) can be fastened together using snap fasteners, buttons, hook-and-loop fasteners, or thread. In this embodiment, snap fasteners are used, so the shoulder belt cover (16) can be fastened without removing the backpack hook (6) provided in the center of the shoulder belt. If the backpack hook (6) is attached to the shoulder belt (3), the upper shoulder belt part (4) and lower shoulder belt part (5) can be separated and the long edges of the shoulder belt cover main part (7) can be sewn together with thread to make the cylindrical part more sturdy.

[0018] Additionally, the shoulder belt (3) may have a chest strap attached to the center to prevent the shoulder belt from slipping off. In this case, the chest strap cannot be used if a shoulder belt cover sewn with thread is attached. Therefore, if the main part of the shoulder belt cover (7) is made with snap buttons, buttons, or hook-and-loop fasteners, the chest strap can be used by extending it from between the buttons to the outside of the shoulder belt cover (16). In the case of a shoulder belt cover (16) sewn with thread, a slit is made from the center to the top of the main part of the shoulder belt cover (7) where the chest strap is attached, and the edge of the fabric is reinforced with stitching. The chest strap can also be formed so that it can be extended from the slit to the outside of the shoulder belt cover (16).

[0019] Next, a fastener for fastening the shoulder belt cover (16) to the shoulder belt (3) will be described. A fastener for securing the shoulder belt cover (16) to the shoulder belt (3) is provided at the top of the shoulder belt cover main part (7). In this embodiment, the elastic cord (11) is passed through the spring cord stopper (10) in advance and folded in half. The elastic cord (11) is then passed through a guide tube (8) made of the same fabric as the shoulder belt cover main part (7) on the upper short side of the shoulder belt cover main part (7) that is wide enough to accommodate two elastic cords. A cord end stopper (9) is attached to the end of the elastic cord (11). When the shoulder belt cover (16) is put on, pulling the elastic cord (11) protruding from the spring cord stopper (10) causes the elastic cord (11) to contract, with the cord end stopper (9) acting as an anchor. The contraction force of the elastic cord (11) secures the shoulder belt cover (16) to the shoulder belt (3). In addition, the fastener of the present invention may use a hook and loop fastener, a hook button, a button, a clip, or a buckle instead of the elastic cord, spring cord stopper, or cord end stopper.

[0020] Next, the ejection mechanism of the shoulder belt cover (16) will be described. As shown in Figure 1, the discharge mechanism is comprised of the part above the fixing device of the shoulder belt cover main part (7) and the discharge part (12) that protrudes outward. When the shoulder belt cover (16) is attached to the shoulder belt (3), this discharge mechanism surrounds the shoulder belt (3) at its upper end, allowing external factors that come into contact with the shoulder belt (3) to be discharged to the outside. In this way, rain, snow, mud, dust, and chemicals can be prevented from flowing along the shoulder belt cover main part (7) and affecting the shoulder belt (3) or the main body of the backpack, sack, or back-mounted industrial machine (1).

[0021] Next, a method for storing the shoulder belt cover (16) will be described. As shown in Figure 5, the shoulder belt cover (16) can be folded compactly and stored by wrapping the double elastic cord of the fastener around the outer periphery of the folded shoulder belt cover, passing it through the elastic cord and securing it with a spring cord stopper. Alternatively, a storage device (15) can be provided at the bottom of the shoulder belt cover (16) to allow the shoulder belt cover to be folded compactly and stored.

[0022] In addition to storing the storage device (15), it can also be used to temporarily attach the shoulder belt to the top of the shoulder belt. For example, when hiking, commuting to work, school, or cycling in weather that may suddenly start raining, the user can use the storage device (15) to enclose the entire long side of the shoulder belt cover main part (7) around the top joint between the shoulder belt and the backpack, rucksack, or backpack-type industrial machine, and fold it up and prepare it for use. While it is preferable to store it above the shoulder belt, this may get in the way depending on the shape of the backpack. In this case, it is best to store it below the shoulder belt, depending on the shape of the backpack.

[0023] The present invention is advantageous for the user wearing the shoulder belt in that the shoulder belt can be used normally after it has been protected from external factors. [Industrial Applicability]

[0024] The present invention can be applied to various products such as backpacks, sacks, and backpack-type industrial machinery that are equipped with shoulder straps. [Explanation of symbols]
