Description

[Detailed description of the invention] [Field of application] The present invention relates to a corner protector for hanging ropes on luggage, such as when transporting furniture or other large luggage, and is used to protect the corners of luggage. is sufficient, and also aims to increase its own strength against rope tension.

[Prior art and its problems] When transporting large loads 5 such as furniture, these loads are fixed with ropes 6. Conventionally, as shown in FIG. In order to avoid concentration of tension on the corners 51 of the cargo, wooden backing plates 1,
1 is guessed, and rope 6 is hung from above.

According to this method, the tension of the rope 6 is dispersed by the backing plates 1, 1 and acts on the surface of the cargo, so there is no inconvenience caused by the tension of the rope 6 being concentrated at the corner 51, that is, at each rope hook. Damage to the corner portion 51 corresponding to this can be prevented.

However, in this conventional device, the surface of the cargo that the cover plates 1, 1 contact is likely to be damaged due to vibration during transportation.

This is because the surfaces of the conventional backing plates 1, 1 have high rigidity, and each surface directly contacts the surface of the luggage 5 such as furniture.

As a corner abutment tool A that solves this inconvenience, one having a structure as shown in FIGS. 3 and 4 can be considered. This device exhibits the same effect as the idea disclosed in Japanese Utility Model Application Publication No. 52-76486, and as shown in the same figure, the back surfaces of the backing plates 1, 1 are covered with a protective layer made of soft synthetic resin. Therefore, the structure is such that they are integrally covered and connected.

In this case, in the contact part with the surface of the baggage 5,
Due to the presence of the protective layer, the tension of the rope 6 acts in a distributed manner on the surface of the luggage 5 through each backing plate and the protective layer in the packing state. In addition, since the contact surface with the baggage 5 is a protective layer made of soft synthetic resin (non-woven fabric in the case of the above-mentioned publication), the vibration contact between the corner protector A and the surface of the baggage 5 due to vibration during transportation may occur. Inconveniences such as damage to the surface of the luggage 5 due to this can be prevented.

However, this improved example has a problem of insufficient durability.

Since each patch plate is connected only by a protective layer made of soft synthetic resin, if used for a long period of time, rope tension will be applied to the joints between the patch plates, which are made only of the soft synthetic resin layer. This is because the resulting tension acts repeatedly, and the protective layer is torn to pieces by this repeated load upon final application.

In other words, the protective layer placed on the back of the backing plate needs to be flexible from the perspective of protecting the surface of the cargo, but generally flexible materials have poor mechanical strength, and the tension caused by the rope can be repeatedly applied. This is because sufficient durability cannot be exhibited in areas where the material is exposed to excessive force.

[Technical Problem] The present invention is based on the above-mentioned method, in which a protective layer having sufficient rigidity and flexibility is integrally attached and fixed to the back surfaces of the backing plates 1, 1 which are parallel to each other. , a corner protector for hanging a rope which is designed to prevent damage to the cargo surface due to contact between the backing plates 1 and 1 by means of this protective layer, in which the rope tension is applied to the backing plates 1 and The backing plates 1 and 1 are mechanically connected to each other in order to prevent the protective layer integrally attached to the back surfaces of the backing plates 1 and 1 from being torn apart even if a repulsive force acts between them. The technical challenge is to do so.

[Technical Means] The technical means of the present invention taken to solve the above-mentioned technical problem is as follows. The engaging portions and the back surface thereof are made to protrude toward the front surface from the flat surface portion on the back surface side of the backing plates 1, 1, and a raised portion 7 is provided near the free end on the front side of the cross section of each backing plate 1. ” was formed.

[Operation] The above technical means of the present invention operates as follows.

The above-mentioned corner pads are used in the same manner as conventional ones, but the corner portions 51
When applied to the corner portion 51, the engaging portion and the back surface of the backing plates 1, 1 protrude toward the front surface side than the flat portion of the back surface of the backing plates 1, 1. It will be located far away from. That is, a predetermined space is created between the back surface of the engaging portion and the corner portion 51. A raised portion 7 continues over the entire length of the back plate 1 at a distance substantially equal to the width of the back plates 1, 1 from this point. Therefore, this corner 51
When the rope 6 is hung on the part, this rope 6 becomes
It comes into contact with the top of the surface side of the engagement part and the raised parts 7, 7 on both sides thereof.

Thereby, the tension of the rope 6 reaches the surfaces of the flat parts 52 and 53 from the protective layer of the flat part on the back side through the contact parts with the backing plates 1 and 1.

[Effects] Since the present invention has the above configuration, it has the following unique effects.

Since the opposing sides of the backing plates 1, 1 are mechanically connected to each other by the interlocking portions, durability is improved compared to the conventional ones described above. That is, even after long-term use, there will be no inconvenience such as the protective layer on the back surface that connects the backing plates 1 and 1 being torn to pieces.

In addition, since the tension of the rope 6 is distributed to the flat part of the back surface through the engaging portions of the backing plates 1, 1 and the raised portions 7, 7, this tension is uniformly distributed to the back surface of the backing plates 1, 1. Therefore, there is no need to worry about the tension of the rope 6 being biased and acting on the load 5.

[Example] Hereinafter, an example of the present invention will be described based on FIG. 1.

The rope hanging corner support tool of the illustrated embodiment is composed of a pair of backing plates 1, 1 made of rectangular plate-like pieces with a uniform cross section, as in the conventional example described above. A soft synthetic resin layer is attached and fixed as a protective layer to the back side of the backing plates 1, 1, and this soft synthetic resin layer is attached from the back side of the engagement part of the backing plates 1, 1 to the back flat part of the backing plates 1, 1. A connecting portion 2 made of soft vinyl chloride, and an anti-slip layer 3 made of a synthetic resin layer of the same material attached to the free end side of the flat back portion.

As shown in the same figure, the engaging portion consists of a combination of a concave portion 8 provided on one patch plate 1 and a convex portion 9 provided on the other patch plate 1. In this embodiment, the mating plate 1, 1 The distal end side of the forming portion of each concave portion 8 is a convex portion 9, and the opposing sides of the backing plates 1, 1 are doubly engaged with each other in a concave-convex relationship.

Further, the front side of the backing plate 1 has an inclined surface extending from the opposite side portion serving as the engagement portion to the free end portion, and is provided with a raised portion 7 near the free end portion. The back side of the forming part of the concave part 8 and convex part 9, which become the engaging part, becomes an arc-shaped concave part, and when the cross sections of the backing plates 1, 1 are orthogonal to each other, as shown in the figure, the back side of the engaging part becomes an arcuate concave part. An arcuate space is formed on the side.

The backing plates 1, 1 having the above structure are both made of hard vinyl chloride resin and manufactured by extrusion molding. Therefore, these backing plates 1,
1 has sufficient rigidity.

In this embodiment, the soft vinyl chloride resin layer attached to the back surface of the backing plates 1, 1 was formed at the center and both ends, but the conventional improved example (FIGS. 3 and 4) ), the effect of the present invention remains the same even if the protective layer is integrally attached to the entire back surface.
