Description

The present invention relates to a hanging device for small items for use as a bag hanger for bags such as school bags.

Conventionally, as shown in FIG. 9, this type of hanging device for small items for bags has an installation space 13 for an auxiliary belt 12 provided above a vertically elongated flat contact plate 11, and a hook portion 15 for holding a loop 14 provided below the installation space 13, and the auxiliary belt 12 is held in the installation space 13 by a fixed cover 16 (Patent Document 1).

The contact plate 11 is a vertically elongated member with a rounded bottom end and a flat top end, and is made of synthetic resin, which gives the contact plate 11 elasticity that allows it to deform and return to its original shape in response to the movement of the leather of a bag such as a school bag.

In the conventional bag accessory hanging device configured in this way, the fixed cover 16 of the auxiliary belt 12 is separated from the contact plate 11, so the attachment work to the auxiliary belt 12 can be performed much more efficiently than before, and accessories of various shapes and sizes can be freely attached to this auxiliary belt, making it possible to widely meet the various needs of users for bags.

However, in the bag accessory hanging device described in Patent Document 1, the contact plate 11 is a flat, oblong member, so when attached to the auxiliary belt 12, it floats slightly above the contact surface with the side of the bag, which can be unsightly, and fingers can get caught in the floating part when in use. For this reason, the contact plate 11 is riveted to the side of the bag by passing a rivet 18 through a rivet hole 17 provided in the lower part of the contact plate 11, which is troublesome and has the problem of damaging the side of the bag due to the riveting.

Furthermore, in the bag accessory hanging device described in Patent Document 1, even though the fixed cover 16 of the auxiliary belt 12 is separate from the contact plate 11, the upper end of the contact plate 11 is passed between the auxiliary belt 12 and the bag, the fixed cover 16 is placed over the auxiliary belt 12, and the rivets 18 are passed through the rivet holes 19 in the fixed cover 16 to rivet it to the auxiliary belt 12, which is a cumbersome and time-consuming process.

The present invention aims to solve the problems of the past and provide a hanging device for small items on a bag that is easy to install, does not float off the side of the bag, and does not damage the side of the bag.

The accessory hanging device for a bag of the present invention is a vertically elongated plate-like body 1 curved so as to warp out in an arc, with a substantially upper half serving as a fastening portion 2 for fastening to an auxiliary belt B horizontally provided on the side portion Ka of the bag K, and a substantially lower half serving as a contact plate portion 3 for contacting the side portion Ka of the bag K. A support portion 4 for rotatably supporting an attachment ring R is integrally molded with the plate-like body 1, and the fastening portion 2 has an inward flange 2a formed at the upper end, and below the inward flange 2a is a support portion 4 for supporting an attachment ring R rotatably. An insertion space S for the auxiliary belt B is provided, and rivet holes 2b for fastening the auxiliary belt B with rivets V are provided from the front to the back surface. The contact plate portion 3 is formed with an inward reinforcing flange 3b from the lower portion 3a to both side ends, and this reinforcing flange 3b gradually protrudes higher from the lower portion 3a of the contact plate portion 3 to both side ends so that when the contact plate portion 3 is contacted against the side portion Ka of the bag K, the contact surface F is in close contact with the side portion Ka of the bag K.

In the bag accessory hanging device of the present invention, the plate-shaped body 1 is curved so that the vertical cross section is warped in an arc shape.

The following describes in detail the embodiment of the bag accessory hanging device of the present invention with reference to the drawings.

The bag accessory hanger of the present invention is a molded product of synthetic resin, and as shown in Figs. 1 to 4, is a vertically elongated plate-like body 1 whose longitudinal section is curved to warp into an arc, and the upper half is a fastening part 2 for an auxiliary belt B that is horizontally provided on the side Ka of the bag K as shown in Figs. 7 and 8, and the lower half is a contact plate part 3 for the side Ka of the bag K. A support part 4 that rotatably supports an attachment ring R such as a swivel ring or D-ring is integrally molded with this plate-like body 1. The plate-like body 1 can be curved to warp into an arc not only on the longitudinal section but also on the transverse section, as shown in Fig. 5.

The plate-like body 1 has a length of 30-40 mm and a width of 15-25 mm, with the radius of curvature of the arc ra of the vertical cross section being 10-15 cm and the radius of curvature of the arc rb of the horizontal cross section being 30-45 cm, so that it does not protrude too much when attached to the side part Ka of the bag K and is well balanced with the attachment ring R.

The fixing portion 2 has an inward flange 2a at the upper end, and below this inward flange 2a is an insertion space S for the auxiliary belt B that is horizontally installed on the side Ka of the bag K. Rivet holes 2b are provided from the front to the back surface for fixing to the auxiliary belt B with rivets V. A circumferential rib 2c is formed around this rivet hole 2b for aligning the head of the rivet V.

The abutment plate 3 has a width that is almost the same as the maximum width of the mounting ring R, and the lower portion 3a is rounded into a semicircular shape, with inward reinforcing flanges 3b formed from the lower portion 3a to both ends. The reinforcing flanges 3b protrude gradually higher from the lower portion 3a to both ends of the abutment plate 3 so that when the abutment plate 3 is abutted against the side portion Ka of the bag K, the contact surface F comes into close contact with the side portion Ka of the bag K. The reinforcing flanges 3b have rounded corners C on both ends to prevent damage caused by the concentration of bending stress when a bending moment acts on the plate-like body 1.

The support part 4 is bent into a hook shape to have elasticity, and has an attachment space 4a in which the ring-shaped attachment part Ra of the attachment ring R, such as a swivel ring as shown in the figure, is loosely fitted, and an opening 4b is provided on the side of the abutment plate part 3, forming a gap P between the abutment plate part 3 and the attachment part Ra of the attachment ring R. Furthermore, the hook-shaped side surfaces 4c of the support part 4 are inclined from the front to the rear, and the front is shorter than the rear. By doing so, when the attachment part Ra of the attachment ring R is loosely fitted into the attachment space 4a, both ends of the attachment ring R do not protrude significantly from both ends of the abutment plate part 3. Furthermore, the vertical cross-sectional shape of the attachment space 4a of the support part 4 can be made shallow by making it a vertical oval, and the support part 4 can be made flat and not bulky. In this way, the support part 4 is less likely to get in the way when the portable object is not being hung.

The gap P of the support part 4 is narrower than the thickness of the mounting part Ra of the mounting ring R, so that the mounting ring R does not come off accidentally through this gap P. Furthermore, when a tensile force equal to or greater than a predetermined tensile force is applied to the mounting ring R, the support part 4 elastically deforms, and the gap P expands to a value greater than the thickness of the mounting part Ra of the mounting ring R, so that the mounting part Ra of the mounting ring R can slip out and come off through the gap P. Furthermore, when the mounting part Ra of the mounting ring R is pushed into the gap P, the support part 4 elastically deforms, and the gap P expands to a value greater than the thickness of the mounting part Ra of the mounting ring R, so that the mounting part Ra of the mounting ring R can pass through the gap P.

Note that the tensile force equal to or greater than the predetermined tensile force means, in the case of a school bag, a tensile force that is considered too great for an elementary school student to withstand being pulled over or dragged by a bicycle or car, for example, a tensile force of about 8 to 20 kg. However, in the case of bags other than school bags, the tensile force can be set to any desired tensile force depending on the user of the bag.

The mounting ring R can be made of synthetic resin or metal, and the eggplant ring shown in Figure 6 is a die-cast metal product that connects an upper ring body with a horizontally long round shape that forms the mounting part Ra to a lower ring body with a vertically long round shape that forms the hanging part Rb. A protrusion 5 is provided at the connecting part, and a hook part 6 is provided at the bottom of the hanging part Rb at a position opposite the protrusion 5. The base end of a vertically long rectangular spring material 7 is rotatably attached to the protrusion 5, and the tip of the spring material 7 is pressed against the inner surface of the tip of the hook part 6. Furthermore, a reinforcing frame 8 is provided on the hanging part Rb so as to divide the hanging part Rb into two equal parts, left and right.

The bag accessory hanging device of the present invention, configured in this manner, is attached to the side Ka of a bag K, such as a school bag, and is used as follows.

To attach the bag accessory hanging device of the present invention to a bag K such as a school bag, as shown in Figures 7 and 8, insert the auxiliary belt B, which is installed horizontally on the side Ka of the bag K, into the space S of the fixing part 2 of the plate-like body 1, and rivet V is inserted into the rivet hole 2b of the fixing part 2 and riveted to the auxiliary belt B to fix it. Since the plate-like body 1 is curved so that it warps out in an arc, the contact surface F of the abutment part 3 of the plate-like body 1 comes into close contact with the side Ka of the bag K.

To attach the mounting ring R to the bag accessory hanger, push the mounting portion Ra of the mounting ring R through the gap P of the support portion 4 and then through the opening 4b, so that the mounting portion Ra of the mounting ring R fits into the mounting space 4a of the support portion 4.

Therefore, in the case of the bag accessory hanging device of the present invention, when a user such as a schoolchild hangs a small item such as a lunch bag from the attachment ring R and walks or runs, the attachment ring R rotates or swings, but the attachment part Ra of the attachment ring R does not slip out of the gap P and become detached.

Furthermore, the accessory hanging device for bags of the present invention is a vertically elongated plate-like body 1 that is curved so as to warp out in an arc. Therefore, when this plate-like body 1 is attached to the auxiliary belt B, it will not float away from the side Ka of the bag K even if the upper part of the plate-like body 1 is not passed between the auxiliary belt B and the side Ka of the bag K, or the lower part of the plate-like body 1 is not riveted to the side Ka of the bag K. This makes the installation process simple and time-saving, does not spoil the appearance, and prevents users such as school children from getting their fingers caught when using it.

The accessory hanger for bags of the present invention is a vertically elongated plate-like body that is curved so that it warps out in an arc, and furthermore, inward reinforcing flanges 3b are formed from the lower portion 3a of the contact plate portion 3 to both side ends, so that this plate-like body 1 is strong and will not float off the side of the bag or break even if a user such as a schoolchild hits it hard against a desk or table.
