Description

  The present invention is mounted along the outer surface of a user's body, and causes friction between the body pressed against the body of the user and the body, thereby preventing the luggage from falling and transporting the luggage. TECHNICAL FIELD The present invention relates to a baggage carrying aid to assist and a manufacturing method thereof.

  A courier deliveryman or the like sometimes carries a luggage in a cardboard box while holding it by the armpit. At this time, the luggage is sandwiched between the waist side surface and one hand, but if the luggage slips on the waist side surface, the luggage may fall. For this reason, the delivery person or the like needs to press the luggage firmly against the side surface of the waist to prevent the luggage from slipping off against the side surface of the waist, which has consumed the physical strength. In addition, when the luggage is heavy, sometimes it is necessary to give up the luggage with one hand and hold it with both hands. If you hold your luggage with both hands, you will have to put it somewhere every time you open or close the doors or gates or operate the buttons of the chime or elevator, which will reduce the efficiency of your transportation work.

  In view of such a situation, a baggage carrying assisting tool for holding a baggage on the side of an arm and making it easy to carry has been proposed so far. For example, in FIG. 3 of Patent Document 1, a baggage including a belt-shaped main body 1, a mounting portion 2 provided at one end of the main body 1, and an abutting portion 3 provided at the other end of the main body 1. A transporting aid (described as "a luggage holding aid" in the same document) is described. The baggage transporting aid of the same document is designed so that the baggage C can be easily carried by hanging the main body 1 on the lower side of the baggage C without looseness and distributing the force applied to the arm. The document also describes that the surface of the contact portion 3 is provided with a minute convex portion 3c (see FIG. 5 of the document) for preventing slippage. In the following, like the baggage transporting aid of Patent Document 1, a baggage transporting aid that assists the transport of luggage by hanging the band material under the luggage to disperse the force applied to the arm. May be referred to as a "belt-carrying type baggage carrying aid".

  Further, FIG. 2 and the like of Patent Document 2 describe a luggage carrying assisting tool including a luggage placing portion 5 and a stopper portion (sandwiching portion 3) for stopping the luggage placing portion 5 on the waist belt 2. .. The baggage transporting aid of the document is designed to carry a baggage easily by placing the baggage on the upper surface of the plate-shaped baggage loading section 5 that projects horizontally and dispersing the force applied to the arm. In the following, like the luggage carrying aid of Patent Document 2, the luggage carrying assistance is designed to assist carrying of luggage by placing the luggage on a horizontally protruding plate-like portion and dispersing the force applied to the arm. The tool may be referred to as a "plate-shaped part-mounting type baggage carrying aid". In addition to the one described in Patent Document 2, a number of plate-shaped member mounting type luggage carrying aids have been proposed (see, for example, FIG. 6 of Patent Document 3).

  However, in the baggage-carrying type baggage carrying aid, if the size of the baggage is small, there is a possibility that the bandgage to be hung around the lower side of the baggage may be left over, making it difficult to carry the baggage. Further, when the luggage is not transported, the band member hangs down from the waist belt, which may cause the band member to be entangled or caught by surrounding objects.

  On the other hand, the load carrying aid of the plate member mounting type can be suitably used even when the size of the load is small. Further, it does not have a band member that causes entanglement or the like. However, in the load carrying aid of the plate member mounting type, the plate portion on which the load is placed projects outward from the side surface of the waist. For this reason, when the luggage is not transported, the plate-shaped portion may collide with a hand or surrounding objects.

  In this regard, in the baggage carrying aid of Patent Document 3, as shown in FIG. 5 of the document, it is possible to fold the plate-like portion (“receiving plate 5” in the document) when the baggage is not carried. Is becoming However, it is troublesome to repeat opening and closing of the plate-shaped portion every time the user tries to carry the luggage or finishes carrying the luggage, and there is an undeniable possibility that the plate-shaped portion will be used as it is.

  The present invention has been made to solve the above-mentioned problems, and not only prevents the luggage from slipping off against the body of the user (delivery person, etc.), but also during use (when carrying the luggage. ) And when not in use (when not carrying luggage), it provides a luggage carrying aid that is not bulky and does not hit surrounding objects. It is also an object of the present invention to provide a method of manufacturing a luggage carrying aid for manufacturing the luggage carrying aid.

The above problems are
It is a baggage carrying aid that is attached along the outer surface of the user's body and that prevents the falling of the baggage and assists in carrying the baggage by causing friction with the baggage pressed against the outer surface. There
A plate-like non-slip member, the outer surface of which is a luggage-side friction surface that contacts the luggage, and the inner surface of which is a body-side friction surface that contacts the body,
It is configured with a mounting member for mounting the plate-shaped non-slip member on the body,
The plate-shaped anti-slip member
A luggage-side elastic layer that forms a luggage-side friction surface,
A body-side elastic layer forming a body-side friction surface,
The present invention provides a baggage carrying aid characterized by comprising a core material layer made of a planar core material disposed between a luggage-side elastic layer and a body-side elastic layer.

  In the baggage transporting aid of the present invention, the portion (plate-shaped non-slip member) that prevents the baggage from slipping off has a plate shape, and is attached along the outer surface of the user's body. Therefore, it does not become bulky when used (when carrying luggage) and when not in use (when not carrying luggage), and it is hard to hit surrounding objects and is excellent in usability. There is.

  Further, the baggage carrying aid of the present invention mainly prevents the baggage from slipping off due to the frictional force generated between the outer surface of the plate-shaped anti-slip member (the baggage side friction surface) and the baggage. Therefore, as long as the load can be pressed against the load-side friction surface of the plate-shaped anti-slip member, it is possible to assist the load transportation regardless of the size of the load.

  However, if the plate-shaped anti-slip member may move with respect to the body of the user, the position of the load may not be determined, which may make it difficult to carry the load. In this respect, in the baggage transporting aid of the present invention, not only the outer surface of the plate-shaped anti-slip member but also the inner surface is a friction surface. Therefore, when the load is pressed against the luggage-side friction surface of the plate-shaped anti-slip member, the body-side friction surface of the plate-shaped anti-slip member is pressed against the user's body, and the body of the plate-shaped anti-slip member is pressed. It is also possible to prevent the plate-like anti-slip member from moving relative to the user's body by the frictional force generated between the side friction surface and the user's body.

  Further, in the baggage carrying aid of the present invention, since the baggage side friction surface and the body side friction surface of the plate-shaped anti-slip member are elastic layers (layers made of an elastic material), a large friction force can be obtained. It is possible to prevent the luggage from falling off. However, if the entire plate-shaped anti-slip member is made of an elastic material, the plate-shaped anti-slip member may be easily bent. When the plate-shaped anti-slip member bends and becomes curved, the contact area between the load-side friction surface of the plate-shaped anti-slip member and the load is reduced, and the frictional force generated between the plate-shaped anti-slip member and the load is reduced. Will end up. For this reason, it is preferable that the plate-shaped anti-slip member maintain a planar shape. In this respect, in the baggage transporting assisting tool of the present invention, the plate-shaped anti-slip member is provided with the core material layer made of the planar core material, so that the plate-shaped anti-slip member is easily kept flat.

  In the luggage carrying aid of the present invention, the luggage-side elastic layer and the body-side elastic layer of the plate-shaped anti-slip member are not particularly limited as long as they are made of an elastic material. Considering the continuous productivity of the luggage carrier, it is preferable to use synthetic rubber. On the other hand, in consideration of mechanical strength, elasticity, etc., it may be formed of natural rubber (NR) or non-oil resistant rubber containing natural rubber (NR). Natural rubber (NR) has not only excellent mechanical strength but also excellent elasticity, and it is possible to obtain a high friction coefficient.

  In the baggage carrying aid of the present invention, the planar core material forming the core material layer is not particularly limited as long as it can impart shape retention to the plate-shaped anti-slip member, but is preferably a nonwoven fabric. The non-woven fabric has an advantage that it is not only low in cost but also easily integrated with an elastic material (rubber or the like) forming the luggage-side elastic layer or the body-side elastic layer. Further, when a thick non-woven fabric is pressed in the thickness direction, it shrinks in the thickness direction, and it is possible to leave an appropriate elasticity in the plate-shaped anti-slip member while obtaining the rigidity required as the plate-shaped anti-slip member. ..

  In the luggage carrying aid of the present invention, a large number of anti-slip projections may be formed on the luggage-side friction surface and the body-side friction surface of the plate-shaped anti-slip member. As a result, the friction coefficient of the luggage-side friction surface (maximum static friction coefficient for luggage) and the friction coefficient of the body-side friction surface (maximum friction coefficient for body) can be increased. Although the form of the non-slip protrusions is not particularly limited, a large number of luggage-side anti-slip protrusions having a “V” shape in front view (“V” shape with the upper side open) are formed on the luggage-side friction surface. It is preferable that a large number of body-side anti-slip projections having an inverted “V” shape (a “V” shape with the lower side opened) are formed on the friction surface.

  On the luggage-side friction surface of the plate-shaped anti-slip member, when the luggage tries to shift from the upper side to the lower side, as described above, the anti-slip projections formed on the luggage-side friction surface (the luggage-side anti-slip projections) are formed. By forming the shape of the letter “V” with the upper side opened, the load (friction force) received by the load from the load-side friction surface can be further increased. In addition, the plate-like anti-slip member moves the user's body from the upper side to the lower side, and as described above, the anti-slip protrusion (body-side anti-slip protrusion) formed on the body-side friction surface is moved downward. By forming the “V” shape that is open to the side, the resistance force (friction force) that the body side friction surface receives from the body can be increased.

  Here, the luggage-side anti-slip protrusion may be formed in a simple "V" shape, but its upward surface (a surface whose normal vector has a vertically upward component. Therefore, an obliquely upward surface is also included. The same shall apply hereinafter) is preferably formed in a stepwise manner. This is because the surface of the corrugated cardboard box that is generally used for carrying luggage and the surface of building materials are often powdery because fine powder such as paper powder and dust is attached. The fine powder adhering to the surface of the load acts to reduce the frictional force of the load-side friction surface of the plate-shaped anti-slip member. In this respect, by forming the upward surface of the luggage-side anti-slip protrusion in a stepwise manner, a plurality of upward edges are formed on the upward surface, and even if the surface of the luggage is powdery, This is because it is possible to make it difficult to slip off.

  As described above, according to the present invention, not only is the luggage prevented from falling down against the body of the user (delivery person, etc.), but also during use (when transporting the luggage) and when not in use (transporting the luggage). It is possible to provide a baggage carrying aid that is not bulky and does not bump into surrounding objects. It is also possible to provide a method of manufacturing a luggage carrying aid for manufacturing the luggage carrying aid.

It is the perspective view which showed the state which looked at the luggage conveyance assistance tool which concerns on this invention from the outer surface side. It is the perspective view which showed the state which looked at the luggage conveyance assistance tool which concerns on this invention from the inner surface side. It is the photograph which image | photographed the state which attached the baggage conveyance auxiliary tool which concerns on this invention to the body.

It is the figure which showed the outer surface of the plate-shaped non-slip member in the luggage conveyance assistance tool which concerns on this invention. It is the figure which showed the inner surface of the plate-shaped non-slip member in the luggage conveyance assistance tool which concerns on this invention.

A preferred embodiment of the luggage carrying aid of the present invention will be described more specifically with reference to the drawings. FIG. 1 is a perspective view showing a state in which a luggage carrying aid 10 according to the present invention is viewed from the outer surface side (the luggage side friction surface α ₁ side). FIG. 2 is a perspective view showing a state in which the baggage carrying aid 10 according to the present invention is viewed from the inner surface side (the body side friction surface α ₂ side). FIG. 3 is a photograph of a state in which the luggage carrying aid 10 according to the present invention is attached to the body.

  As shown in FIG. 3, the luggage carrying aid 10 of the present invention is attached along the outer surface of the user's body. The baggage carrying aid 10 of the present invention can be attached to any part of the user's body where the baggage during carrying may be pressed. For example, when carrying a luggage with both hands, the luggage is in a state of being pressed against the front of the chest or abdomen. When such a carrying mode is assumed, the luggage carrying aid 10 is placed on the chest. And can be attached to the front of the abdomen.

  However, the baggage carrying aid 10 of the present invention can be used particularly suitably when carrying a baggage with one hand by pinching it under the armpit. This is because, as already mentioned, when carrying luggage by sandwiching it under the armpit, the arm strength is likely to be exhausted. However, when the luggage carrying aid 10 of the present invention is used, it is possible to carry a bag with a certain weight or a certain size. Even if there is, it can be easily transported without wasting so much strength. In the case of assuming a transportation mode in which the luggage is sandwiched between the armpits, the luggage transportation aid 10 is attached to the side surface of the waist or the side surface of the abdomen. The baggage transporting aid 10 of the present embodiment is also assumed to be attached along the side surface of the waist of the user.

As shown in FIG. 1, the baggage carrying auxiliary tool 10 of the present invention includes a plate-shaped anti-slip member 11 and a mounting member 12. Hereinafter, each of the plate-shaped anti-slip member 11 and the mounting member 12 will be described in detail.

[Plate-shaped non-slip member]
The plate-shaped non-slip member 11 is a plate-shaped member that is sandwiched between the luggage and the user's body (waist). The outer surface of the plate-shaped non-slip member 11 (the surface that faces the outside when viewed from the user when attached to the user's body) is brought into contact with the luggage, and the luggage is displaced downward due to the frictional force at that time. The friction surface α ₁ on the luggage side is provided so as to prevent it. On the other hand, the inner surface of the plate-shaped non-slip member 11 (the surface facing the user when attached to the user's body) contacts the user's body (waist), and the plate-shaped anti-slip member 11 is attached to the body. It is a body-side friction surface α ₂ so as not to slide down to the (waist). As shown in FIG. 1, the luggage-side friction surface α ₁ is formed with a large number of luggage-side anti-slip projections β _1, and the body-side friction surface α ₂ is provided with a large number of body parts as shown in FIG. A side anti-slip protrusion β ₂ is formed.

As shown in FIG. 4, the plate-shaped non-slip member 11 includes a luggage-side elastic layer 11a forming a luggage-side friction surface α ₁ , a body-side elastic layer 11b forming a body-side friction surface α ₂ , and a luggage-side elastic layer 11b. The elastic layer 11a and the body-side elastic layer 11b are composed of a core material layer 11c made of a planar core material. FIG. 4 is a cross-sectional view showing a state in which the baggage carrying auxiliary tool 10 according to the present invention is cut along a vertical plane including the center line in the width direction. In this way, by using the outer surface (baggage side friction surface α ₁ ) side and the inner surface (body side friction surface α ₂ ) side of the plate-shaped anti-slip member 11 as elastic layers, the baggage side friction surface α ₁ and the body side it is possible to the friction surface alpha ₂ increased frictional resistance to impart rubber elasticity luggage side friction surface alpha ₁ and body-side friction surface alpha _2. However, if the entire plate-shaped anti-slip member 11 is made of an elastic layer, the plate-shaped anti-slip member 11 is likely to bend, and the contact area between the load-side friction surface α ₁ and the load may be reduced. In this respect, by providing the core material layer 11c between the luggage-side elastic layer 11a and the body-side elastic layer 11b, the shape of the plate-shaped anti-slip member 11 can be easily kept flat.

  The luggage-side elastic layer 11a and the body-side elastic layer 11b are formed of an elastomer (elastic material). Examples of the elastomer forming the luggage-side elastic layer 11a and the body-side elastic layer 11b include thermosetting elastomers and thermoplastic elastomers. Among these, as the thermosetting elastomer, in addition to natural rubber (NR), ethylene propylene diene rubber (EPDM), butadiene rubber (BR), nitrile butadiene rubber (NBR), styrene butadiene rubber (SBR), Examples include isoprene rubber (IR), butyl rubber (IIR), chloroprene rubber (CR), acrylic rubber (ACM), synthetic rubber such as urethane rubber (U), silicone rubber (SI), and fluororubber (FKM). Be done. On the other hand, examples of the thermoplastic elastomer include a styrene-based thermoplastic elastomer (TPS), an olefin-based thermoplastic elastomer (TPO), a vinyl chloride-based thermoplastic elastomer (TPVC), an ester-based thermoplastic elastomer (TPEE), and an amide. An example is a thermoplastic elastomer (TPAE).

  The luggage-side elastic layer 11a and the body-side elastic layer 11b can be formed of various elastomers having rubber elasticity as described above. In the baggage carrying aid 10 of this embodiment, the baggage side elastic layer 11a and the body side elastic layer 11b are formed of synthetic rubber in consideration of the continuous productivity of the plate-shaped anti-slip member 11. However, if importance is attached to the mechanical strength and elasticity of the plate-shaped anti-slip member 11, the luggage-side elastic layer 11a and the body-side elastic layer 11b contain natural rubber (NR) or natural rubber (NR). It can also be formed of non-oil resistant rubber. This is because natural rubber (NR) has not only excellent mechanical strength but also excellent elasticity, and it is possible to obtain a high friction coefficient (provided that synthetic rubber is used. However, if isoprene rubber (IR) or the like is used, it is possible to obtain mechanical strength and elasticity close to those of natural rubber (NR). When the luggage-side elastic layer 11a and the body-side elastic layer 11b are formed of non-oil resistant rubber containing natural rubber (NR), the content of natural rubber (NR) is not particularly limited, but is 30% by weight or more. Preferably.

The luggage-side elastic layer 11a and the body-side elastic layer 11b may be adhered to the core material layer 11c arranged therebetween, but it is preferable to integrally form the core material layer 11c. In the baggage transporting assisting tool 10 of the present embodiment, the sheet-like core material forming the core material layer 11c is provided between the rubber sheet forming the luggage-side elastic layer 11a and the rubber sheet forming the body-side elastic layer 11b. The baggage side elastic layer 11a, the body side elastic layer 11b, and the core material layer 11c are integrally formed by compression molding in the sandwiched state. The luggage-side anti-slip protrusion β ₁ and the body-side anti-slip protrusion β ₂ are also formed during this compression molding.

The forms of the luggage-side anti-slip protrusion β ₁ and the body-side anti-slip protrusion β ₂ are not particularly limited. In the baggage transporting aid 10 of the present embodiment, the baggage side anti-slip protrusion β ₁ has a “V” shape in front view (a “V” shape with the upper side open), as shown in FIG. 1. When the luggage tries to move from the upper side to the lower side with respect to the luggage side friction surface α ₁ , the luggage side anti-slip protrusion β ₁ has a “V” shape with the upper side open, so that the luggage side can luggage increased resistance (friction force) received from load side friction surface alpha ₁ that when going to move to the lower side of the friction surface alpha _1.

In addition, the load-carrying aid 10 of the present embodiment, the upward surface of the luggage side slip projections beta ₁ forms in a stepped shape, by forming a plurality of upwardly edges luggage side slip projections beta ₁ There is. Accordingly, even when such fine powder to the surface of the pressing was luggage load side friction surface alpha ₁ is attached, so as not slip luggage against load side friction surface alpha _1, luggage The side anti-slip protrusion β ₁ can provide resistance. As already mentioned, the surface of corrugated cardboard boxes, which are generally used for transporting luggage, and the surfaces of building materials, where fine powder such as paper powder adheres, is often powdery. , It is possible to prevent slipping even with such a cardboard box.

The height H ₁ (FIG. 4) of the luggage-side anti-slip protrusion β ₁ is not particularly limited. However, if the height H _{1 of} the luggage-side anti-slip protrusion β ₁ is too low, it may not be possible to secure a large resistance force by the luggage-side anti-slip protrusion β ₁ . In particular, when the upward facing surface of the luggage-side anti-slip protrusion β ₁ is formed in a stepped shape, the number of steps cannot be secured, and it becomes difficult to improve the slip resistance against the luggage to which the powder adheres. When forming the upward surface of the luggage-side anti-slip protrusion β _{1 in} a stepwise manner, the number of steps is usually 2 to 10 steps, preferably 3 to 7 steps. Therefore, the height _{H 1} of the luggage side slip projections beta ₁ is usually a 1mm or more. The height H ₁ of the luggage-side anti-slip protrusion β ₁ is preferably 2 mm or more, and more preferably 3 mm or more.

On the other hand, too high a height H ₁ of the luggage side slip projections beta _1, there is a possibility that it is difficult to maintain the strength of the load-side slip projections beta _1. Therefore, the height _{H 1} of the luggage side slip projections beta ₁ is usually a 10mm or less. The height H ₁ of the luggage-side anti-slip protrusion β ₁ is preferably 7 mm or less, and more preferably 5 mm or less. In load carrying aid 10 of the present embodiment, the height H ₁ of the luggage side slip projections beta ₁ is a about 4 mm, the number of stepped upward surface in luggage side slip projections beta _1, 4 It is a step.

FIG. 5 is a diagram showing an outer surface (a luggage-side friction surface α ₁ ) of the plate-shaped anti-slip member 11 in the luggage transportation aid 10 according to the present invention. The lateral length L ₁ (FIG. 5) of the luggage-side anti-slip protrusion β ₁ is preferably about 5 to 30 mm, more preferably about 10 to 20 mm. In load carrying aid 10 of the present embodiment, Horizontal L ₁ luggage side slip projections beta ₁ has a approximately 13 mm. The length L ₂ (FIG. 5) of the luggage-side anti-slip protrusion β ₁ is preferably about 2 to 20 mm, more preferably about 5 to 15 mm. In the baggage transporting aid 10 of the present embodiment, the vertical length L ₂ of the baggage side anti-slip protrusion β ₁ is about 8 mm. Further, the opening angle θ ₁ (FIG. 5) of the luggage-side anti-slip projection β ₁ is preferably 30 to 150 °. In load carrying aid 10 of the present embodiment, the opening angle theta ₁ of the luggage side slip projections beta ₁ has a approximately 90 °.

Arrangement of the luggage-side anti-slip projections β ₁ is not particularly limited, but in the luggage transportation aid 10 of the present embodiment, a plurality (usually 5 to 30, preferably 10) arranged in the vertical direction (up and down direction). A row of (20 pieces) luggage-side anti-slip projections β ₁ is arranged in parallel (usually 2 to 20 rows, preferably 5 to 10 rows) in the lateral direction (horizontal direction). The vertical arrangement pitch P ₁ (FIG. 5) of the luggage-side anti-slip projections β ₁ is usually 2 to 20 mm, preferably 3 to 10 mm. In load carrying aid 10 of the present embodiment, the vertical arrangement pitch P ₁ of the luggage side slip projections beta ₁ has a approximately 4 mm. The lateral arrangement pitch P ₂ (FIG. 5) of the luggage-side anti-slip projections β ₁ is usually 7 to 30 mm, preferably 10 to 20 mm. In the baggage transporting aid 10 of the present embodiment, the lateral arrangement pitch P ₂ of the baggage side anti-slip projections β ₁ is about 15 mm.

In contrast to the luggage-side anti-slip protrusion β ₁ described above, the body-side anti-slip protrusion β ₂ has an inverted “V” shape in front view (a “V” shape with the lower side open), as shown in FIG. 2. The plate-like non-slip member 11 is a “V” shape (reverse “V” shape) in which the body side anti-slip protrusion β ₂ is opened when the user tries to move the waist side surface of the user from the upper side to the lower side. By this, the resistance (friction force) that the plate-shaped anti-slip member 11 receives from the waist side surface when the plate-shaped anti-slip member 11 tries to move downward with respect to the waist side surface can be increased.

The body-side anti-slip protrusion β ₂ may have the same size as the luggage-side anti-slip protrusion β ₁ . However, in addition to the plate-shaped anti-slip member 11 being attached to the waist side surface (body) by the attachment member 12, the body-side anti-slip protrusion β ₂ comes into contact with the cloth of clothes or the like. However, the friction is relatively large. Therefore, the body-side anti-slip protrusion β ₂ is not required to have the same level of slip resistance as the luggage-side anti-slip protrusion β ₁ . For this reason, in the luggage carrying aid 10 of the present embodiment, the body-side anti-slip protrusion β ₂ has a different size from the luggage-side anti-slip protrusion β ₁ .

The height H ₂ (FIG. 4) of the body-side non-slip protrusion β ₂ is usually 0.5 to 5 mm. In load carrying aid 10 of the present embodiment, height H ₂ of the body side slip projections beta ₂ is made approximately 2 mm. FIG. 6 is a view showing the inner surface (body-side friction surface α ₂ ) of the plate-shaped anti-slip member 11 in the luggage carrying aid 10 according to the present invention. The lateral length L ₃ (FIG. 6) of the body-side anti-slip protrusion β ₂ is preferably about 5 to 30 mm, more preferably about 10 to 20 mm. In the baggage transporting aid 10 of this embodiment, the lateral length L ₁ (FIG. 5) of the body-side anti-slip protrusion β ₂ is about 13 mm. The length L ₃ (FIG. 6) of the body-side anti-slip protrusion β ₂ is preferably about 2 to 20 mm, more preferably about 5 to 15 mm. In the baggage transporting aid 10 of the present embodiment, the vertical length L ₃ of the body-side anti-slip protrusion β ₂ is about 12 mm. Further, the opening angle θ ₂ (FIG. 6) of the body-side anti-slip protrusion β ₂ is preferably 30 to 150 °. In load carrying aid 10 of the present embodiment, the opening angle theta ₂ of the body side slip projections beta ₂ has a approximately 65 °.

The arrangement of the body-side anti-slip projections β ₂ is not particularly limited, but can be arranged coarser than the luggage-side anti-slip projections β ₁ . In the baggage transporting assisting tool 10 of the present embodiment, the row composed of the plurality of body-side anti-slip protrusions β ₂ arranged in the vertical direction (vertical direction) is arranged in parallel in the horizontal direction (horizontal direction). although the same as the baggage side slip projections beta _1, the body-side slip number of the protrusions beta ₁ is seven constituting the longitudinal direction of the rows, the number of columns in the horizontal direction, and the six columns, either, luggage It is smaller than in the case of the side anti-slip protrusion β ₁ .

  The planar core material forming the core layer 11c is not particularly limited as long as it can impart shape retention to the plate-shaped anti-slip member 11. The planar core material forming the core layer 11c may be made of cloth, resin, metal, or cardboard. However, as described above, when the plate-shaped non-slip member 11 is integrally formed with the luggage-side elastic layer 11a, the body-side elastic layer 11b, and the core material layer 11c by compression molding, the core material layer 11c is made of resin. In the case of forming by, the resin having a higher melting point than the rubber forming the luggage-side elastic layer 11a and the body-side elastic layer 11b is used as the resin.

In the baggage transporting aid 10 of the present embodiment, the planar core material forming the core material layer 11c is a thick non-woven fabric. When a thick non-woven fabric is pressed in the thickness direction, it contracts in the thickness direction and imparts rigidity to the plate-shaped anti-slip member 11, but can leave the plate-shaped anti-slip member 11 with appropriate elasticity. As described above, in the baggage transporting aid 10 of the present embodiment, the plate-shaped anti-slip member 11 is formed by compression molding. At the time of this compression molding, the planar core that forms the core material layer 11c is formed. The material is pressed in the thickness direction. The non-woven fabric has not only a low cost but also an advantage that it can be easily integrated with the rubber material forming the luggage-side elastic layer 11a and the body-side elastic layer 11b.

[Mounting member]
On the other hand, the attachment member 12 is for attaching the plate-shaped anti-slip member 11 to a predetermined location on the user's body. As described above, the luggage carrying aid 10 according to the present embodiment is used by being attached to the side surface of the waist of the user. In the luggage carrying aid 10 according to the present embodiment, the mounting member 12 has a plate shape. It is for attaching the anti-slip member 11 to the waist belt 20 (see FIG. 3) of the user.

Specifically, as shown in FIGS. 1 and 2, the mounting member 12 is attached from the vicinity of the center of the upper edge of the plate-shaped anti-slip member 11 to the inner surface (body-side friction surface α ₂ ) side of the plate-shaped anti-slip member 11. Upper band-shaped portion 12a that is routed to the bottom and a lower band-shaped portion that is routed from the vicinity of the center of the lower edge of the plate-shaped anti-slip member 11 to the inner surface (body-side friction surface α ₂ ) side of the plate-shaped anti-slip member 11. 12b and a strip shape. As shown in FIG. 1, the upper band-shaped portion 12a and the lower band-shaped portion 12b are passed through the through slits 11d provided near the center of the upper edge and near the center of the lower edge of the plate-shaped anti-slip member 11 to form a plate-shaped member. It is pulled out to the inner surface side of the anti-slip member 11, and as shown in FIG. 2, it is in a continuous state on the inner surface side of the plate-shaped anti-slip member 11.

As shown in FIG. 4, the attachment member 12 attaches the plate-shaped anti-slip member 11 to the waist belt 20 by fixing the upper belt-shaped portion 12 a and the lower belt-shaped portion 12 b to each other on the inner surface side of the waist belt 20. It is like this. Adhering portions γ ₁ and γ ₂ are provided at the overlapping portions of the tip portions of the upper strip portion 12a and the lower strip portion 12b. The fixing parts γ ₁ and γ ₂ are not particularly limited in their modes as long as they can be fixed to each other, but in the baggage carrying aid 10 of the present embodiment, they are surface fasteners. The surface fastener is easily peeled off when a peeling force is applied in a direction perpendicular to the surface. In this respect, as described above, by fixing the upper belt-shaped portion 12a and the lower belt-shaped portion 12b on the inner surface side of the waist belt 20, the bag-side friction surface α ₁ of the plate-shaped anti-slip member 11 is loaded with the luggage. When pressed, the surface fasteners (fixed portions γ ₁ and γ ₂ ) receive a force in a direction in which they are pressed against each other, and it is possible to make the surface fasteners difficult to peel off.

[Use]
The baggage transportation aid 10 of the present invention described above not only prevents the baggage from slipping off against the body of the user (delivery person, etc.), but also when used (when carrying the baggage) and when not in use. It is not bulky either at the time (when not carrying luggage). The use of the baggage carrying auxiliary tool 10 of the present invention is not particularly limited, but when a courier delivery member delivers the baggage or when a worker carries the baggage at a business place such as a factory. It can be preferably used.
