Description

The present invention relates to an improvement of a hanging tool attached to a large gusset portion of a school bag.

2. Description of the Related Art Conventionally, a hanging tool for hanging a drawstring bag or the like that accommodates gymnastic clothes, tableware or learning materials used in school is attached to a large gusset portion of a school bag.

Most of the hanging tools are composed of a hanging piece for hanging the drawstring bag, and an attachment piece for attaching the hanging piece to the large gusset portion, and the hanging piece can be easily attached and detached with one touch, and Since it is difficult to come off even if it is handled a little violently, a so-called ring-shaped hanging piece is attached.

In this hanging tool, a mounting piece is fixed to a front fastening belt positioned above the large gusset portion with a fixing pin such as a rivet or a crimping hook, and a drawstring bag is suspended from a hanging piece provided below the mounting piece. The suspension device is prevented from being damaged by being pivotably and swingably attached in accordance with the movement of the drawstring bag.

However, because schoolchildren do not have a sufficient sense of the width of the body and the drawstring bag is greatly swayed, it is hung on the shoulder protrusion on the school road or a tree branch protruding from the fence. Easy to hook a drawstring bag. Furthermore, when an excessive load is applied to the hanging tool when the bag is pulled with friends, the connecting piece portion of the hanging tool may be broken. Furthermore, if the drawstring bag hung on the hanger is caught by a projecting part such as a mirror of an automobile or motorcycle, there is a risk of injury, which is extremely dangerous.

Therefore, in order to solve such problems, when a certain tensile force is applied to the drawstring bag suspended from the hanging tool, the hanging piece can be removed without being damaged from the mounting piece. Suspension devices are known for the purpose of preventing injury and ensuring the safety of school children.

The former includes a first member having an elliptical cross section, a second member having a communication path in a shaft hole pivotally supported by the shaft of the first member, and the second member. When the bag suspended by the suspension member is pulled, the second member pivotally supported by the shaft portion of the first member is composed of an annular suspension member attached to the holding space provided below. By rotating, the communication path of the shaft hole and the narrow shaft portion of the shaft portion are matched, and the second member is detached from the first member and the schoolchild is not pulled and injured. However, the hanging tool has a large number of parts such as the first member, the second member, and the hanging member, is expensive and uneconomical, and requires a lot of work for installation and is inefficient. Further, when the drawstring bag is pulled, the drawstring bag does not necessarily rotate in the horizontal direction, and there is a problem that it is very dangerous if the drawstring bag does not come out unless it is rotated in the horizontal direction.

The latter is a structure that suspends from the gap of the hook part provided in the locking part of the suspension stopper through the attaching part of the eggplant ring. It is to be detached from the stop. Normally, the tensile strength of the hanging tool attached to the school bag is required to have a structure that drops for safety when a tensile force exceeding a certain load is applied, but the elastic deformation of the hook part of the eggplant ring suspension is There is a possibility that it will come off with a tensile force less than a certain load, which is a safety problem.
Furthermore, since the above-described invention device merely suspends the suspended suspension member or eggplant ring with the first member or the hook portion, the suspension member or eggplant ring is only in the rotational direction. The swinging of the suspension member or the eggplant ring becomes unstable and easily breaks. In addition, there is a problem that the hanging member or eggplant ring that swings in the axial direction hits the first member or the hook portion, and abnormal noise is likely to occur.

The present invention aims to improve the mounting work by reducing the number of components of the hanging tool to be attached to the front fastening belt located in the large gusset portion of the school bag, and when it is applied to an annular body with a certain level of tensile force. The ring is securely removed without breakage, and when the suspended ring is swung, it prevents axial vibrations and abnormal noises. An object of the present invention is to provide a hanger having a safe and possible strength.

By forming the entire support tube portion 22 to be thin, the support tube portion 22 is formed so as to be deformable when a certain tensile force is applied. Further, by inserting the tube shaft portion 33 of the decorative plate 31 into the support tube portion 22, the insufficient strength of the support tube portion 22 formed to be thin is reinforced, and when the ring 12 formed is detached. It is possible to prevent the support tube portion 22 from being damaged by an impact due to external pressure deformation.

When a tensile force of a certain load or more is applied to the annular body 12, as described above, the outer peripheral surface of the support cylinder portion 22 is evenly pressed by the downward pressing force generated at the outlet 19 of the communication path 18 of the annular body 12. And deformed to reduce the diameter. The support cylinder portion 22 has an outer peripheral surface that is deformed from an inner diameter width H of the fitting hole 17 to an opening width h of the outlet 19, and the ring body 12 formed by the communication passage 18 coming out of the support cylinder portion 22 can be detached. .

The spring washer 27 is made of a metal material that is thin and formed in a ring shape. For example, the spring washer 27 is thin and has a concavo-convex portion that is continuously waved in the circumferential direction to form an annular shape, thereby providing elasticity. Spring washer 27a (FIG. 7a). Alternatively, a spring washer 27b (FIG. 7B) formed by cutting a portion of a thin plate material formed in a ring shape and twisting the cut surface up and down to give a resilient force as a whole. Furthermore, it is a spring washer 27c (FIG. 7C) formed by inclining between the outer diameter and the inner diameter of a thin metal material formed in a ring shape to give an elastic force.

By suspending the ring body 12 formed by interposing the spring washer 27 in the support cylinder portion 22 between the mounting substrate 21 and the decorative plate 31 while always energizing the ring body 12 in one direction, the ring body 12 is axially oriented. It is possible to prevent the generation of abnormal noise due to the movement to. Further, when the annular body 12 swings in the width direction, rattling or twisting acting in the axial direction is absorbed by the spring washer 27, and when an unexpectedly strong twist acts on the annular body 12, it is supported by the twisting force. It is possible to prevent the ring body 12 formed by the deformation of the cylindrical portion 22 from falling off.

As shown in FIGS. 5 and 6, the decorative plate 31 has a decorative portion 32 formed on the front surface side, and a cylindrical shaft portion 33 that is inserted into the support cylindrical portion 22 of the mounting substrate 21 at the center of the back surface side.

By inserting the tube shaft portion 33 of the decorative plate 31 into the support tube portion 22 of the mounting substrate 21 to form a double, the insufficient strength of the support tube portion 22 is reinforced, and the ring body 12 is formed. The external pressure deformation at the time of detachment is not easily deformed because not only the support tube portion 22 but also the tube shaft portion 33 is deformed at the same time, so that it cannot be removed unless a tensile force exceeding a certain load is applied. Furthermore, it is possible to prevent the support tube portion 22 from being damaged by an impact when the ring body 12 is pulled.

As shown in FIGS. 3, 4, and 10, the back plate 40 has press-fit pins 41 each embedded with a head 44 at a position that matches the pin hole 35 of the bearing tube portion 34 provided on the decorative plate 31. A plurality of annular flanges 43 are formed concentrically at regular intervals on the peripheral surface of the shaft portion 42 of the press-fit pin. By providing the plurality of annular flange portions 43 concentrically, it is possible to prevent the shaft portion 42 press-fitted into the pin hole 35 of the decorative plate 31 from coming off.

Hereinafter, the operation of the embodiment of the present invention will be described. When the hanging tool 11 is attached to the large gusset portion 3a of the school bag 1, the ring formed after the spring washer 27 is inserted into the support tube portion 22 of the mounting substrate 21. Twelve fitting holes 17 are inserted through the support cylinder portion 22. Next, when the cylindrical shaft portion 32 of the decorative plate 31 is inserted into the support cylindrical portion 22 and the bearing cylindrical portion 34 is inserted into the cylindrical hole 23 of the mounting substrate 21 and pushed in, the locking provided at the upper end of the decorative plate 31 is provided. When the collar portion 36 is joined to the surface of the mounting substrate 21 and stopped, the ring body 12 to be formed can be held and suspended by a certain force urged by the spring washer 27.

After the formed ring body 12 is suspended between the attachment substrate 21 and the decorative plate 31, the front fastening belt 8 attached to the large gusset portion 3 is fitted into the belt groove portion 24 of the attachment substrate 21, and then the large gusset portion 3a. The bearing tube portion 34 of the decorative plate 31 is inserted into the hole 9, and the pin shaft 42 of the press-fit pin 41 of the back plate 40 is inserted into the pin hole 35 of the bearing tube portion 24 from the inside of the large gusset portion 3a and suspended. The tool 11 is attached to the large gusset portion 3a.

Conventionally, since it has been attached using fasteners such as hooks and rivets, it must be clamped using a dedicated jig. However, the present invention is a press-fit pin with a head 44 embedded in the back plate 40. The shaft portion 42 of 41 can be easily fixed simply by inserting and crimping. The press-fitted pin 41 that has been press-fitted is provided with a plurality of annular flanges 43 on the peripheral surface of the shaft part 42, so there is no risk of detachment, and the attachment work can be performed efficiently. Furthermore, since the suspending tool 11 is attached to the large gusset portion 3a with a plurality of press-fit pins 41 provided on the back plate 40, there is no possibility that the parts may be separated or damaged by an external impact.

The ring body 12 can be urged in one direction by a spring washer 27 to prevent noise generated when the ring body 12 moves in the axial direction. Further, the generation of an unexpected torsional force generated when the formed ring body 12 swings in the width direction is absorbed by the spring washer 27, and the ring body 12 formed by an unexpected force due to rattling or twisting falls off. Can be prevented.

As shown in FIG. 8, the fitting hole 17 provided in the formed ring body 12 opens a communication path 18 at one end in the axial direction opposite to the hanging direction of the formed ring body 12, and an outlet 19 of the communication path. Is formed with an opening width h slightly narrower than the inner diameter H of the fitting hole 17. Therefore, when the drawstring bag suspended from the formed ring body 12 is hooked and a tensile force of a certain level or more is applied, the support cylinder portion 22 is applied with an equal pressing force in the centripetal direction acting on the outlet 19 of the communication path 18 of the formed ring body 12. By elastically deforming the outer peripheral surface (as shown in FIG. 12), the support shaft portion 22 or the communication passage 18 is not damaged, and it is deformed from the inner diameter H of the fitting hole 17 to the opening width h of the outlet 19 and is removed. It is possible to reliably release the ring 12 formed by the operator. Therefore, since the detached ring body 12 or the support shaft portion 22 has no damaged portion due to the separation, it can be attached and used again, which is very economical.

The schoolchild runs on the backpack 1 in which the purse bag is suspended from the ring 12 formed by the hanging tool 11, or is connected to the fitting hole 17 of the ring 12 that is less than the tensile force of swinging the school bag 1 left and right. Since the pressing force acting on the outlet of the passage 18 is weak and the support shaft portion 22 of the mounting substrate 21 is not deformed, the ring body 12 formed can be reliably supported without being detached from the support cylinder portion 22.

As shown in FIG. 11, the swing range of the ring body 12 hung from the hanger 11 can be swung to the left and right horizontally by being regulated by the left and right bearing tube portions 34 provided on the decorative plate 31. It has been prevented. Therefore, since the drawstring bag suspended on the hanging tool 11 does not swing high during the school, it is prevented from being hooked on a hedge branch or being caught on a protruding part of a vehicle that has passed on a narrow road. be able to.

As mentioned above, if a drawstring bag hung on the hanging tool 11 of the school bag 1 is hooked on a hedge branch or hooked on a protruding part of a vehicle passing by a narrow road while going to school, Alternatively, when a tensile force of a certain level or more is applied, the outer periphery of the support cylinder portion 22 is pressed by the pressing force that acts on the outlet 19 of the communication path 18 by the communication path 18 communicating with the fitting hole 17 being pulled in the opposite direction to the pulling direction. The ring body 12 formed through the communication path 18 can be detached from the mounting substrate 21 while the surface is pressed and deformed in the centripetal direction. Therefore, it is possible to prevent accidents in which schoolchildren are pulled by the bags that are caught and fall down, resulting in safety.

A protective plate (not shown) is interposed between the large gusset portion 3 and the hanging tool 11 so that the surface of the large gusset portion can be prevented from being scratched by the thread caused by the swinging of the hanging tool. Of course
