Description

Bag buffer

The present invention relates to a shock absorber for a bag, and is applied to a hand-held type, a shoulder type, a backpack type, and a bag that combines two or more of them, and reduces the burden on the user's hand, arm, shoulder, and back. In particular, various kinds of bags that can be placed on the shoulder with a shoulder belt, leather strap, band, etc. and can store relatively heavy items, such as golf bags, Boston bags, The present invention relates to a shock absorber for a bag that is more suitable for application to trunks, travel baskets, sports bags, rucksacks, business bags, suitcases, tool bags, shopping bags, and other various bags.

In the conventional golf bag as the background of the present invention, for example, a handle having one end fixed to the upper end portion of the golf bag main body and the other end extended and fixed to the intermediate portion of the golf bag main body and fixed tightly over the entire length (For example, refer to Patent Document 1).
In particular, one end of the handle is fixed to the upper ring at the upper end of the golf bag on which the shoulder belt is hung, and the other end is fixed to the lower ring at the middle of the golf bag on which the other end of the shoulder belt is hung. Thus, the gripping position can be moved in accordance with the movement of the weight center of the golf bag. Therefore, the weight center of the golf bag and the gripping position are located on a common vertical line so that a rotational moment is not generated or is small, and only the weight of the golf bag is applied, so that the golf bag can be easily carried. Yes.
In addition, a number of fixing grooves or fixing rings are formed in the handle in the vertical direction so as to be separated from the shoulder belt at positions close to the center of weight according to the center of weight of the golf bag. The fixing position can be adjusted. Therefore, when the shoulder belt is put on the shoulder, the golf bag is carried in a well-balanced manner and can be carried more easily.

JP 11-114116 A

However, in such a conventional golf bag, as described above, although it is convenient when carrying it, it contains 10 or more golf clubs, golf balls, golf shoes, etc. Since the weight of the golf bag thus obtained is a heavy article having a weight of several tens of kilograms to several tens of kilograms, for example, the golf bag is placed in a state where it is self-supporting from a state where the golf bag is being carried. In such a case, a heavy burden is placed on the user.

That is, in this conventional golf bag, when the golf bag is to be self-supporting from a state in which the handle is held with one hand, for example, the golf bag is lifted with the other hand while the golf bag is lifted with the other hand. After causing the intermediate portion in the vertical direction to be held, an operation to make the golf bag self-supporting is required. In addition, when the golf bag is to be self-supported from the state where the shoulder belt is hung on the shoulder, for example, after gripping the handle with one hand and the shoulder belt part on the upper ring side with the other hand. The operation | movement which makes a golf bag self-supporting is needed. In both the former case and the latter case, it is difficult to perform a series of operations smoothly, and a heavy burden is imposed on the user due to the series of operations.

By the way, in this conventional golf bag, as described above, when the golf bag is made to stand independently from a state where the handle is gripped or a state where the shoulder belt is hung on the shoulder, for example, the gripping position of the handle and the shoulder belt shoulder strap The position of the golf bag is changed so that the position of the center of weight of the golf bag and the gripping position of the handle or the shoulder strap position of the shoulder belt do not coincide with each other on the vertical line, and the golf bag is rotated so that the golf bag becomes independent. It is possible to make it. In other words, the golf bag is rotated in a self-supporting direction and placed on the floor surface or the ground by using a rotational moment generated around the gripping position of the handle or the shoulder position of the shoulder belt.

However, when the golf bag is rotated in a self-supporting direction, the total weight of the golf bag to which the force of the rotational moment is applied becomes a heavy load, and the user's wrist, arm, elbow, shoulder, back, It acted on the waist, knees, etc., and it took a considerable burden. In this case, the greater the weight of the golf bag storage, the greater the total weight of the golf bag and the greater the rotational moment, so the load on the user instantaneously increases. . Therefore, the burden is even greater on the user.

On the other hand, in such a conventional golf bag, in order to carry it from a self-supported state, when holding the handle and lifting the golf bag instantaneously on the spot, or by hanging a shoulder belt on the shoulder When carrying a golf bag or when walking on a rugged place on a staircase or golf course while carrying a shoulder belt, the user's wrist, arm, shoulder, back, waist, elbow, knee In other words, a large dynamic load (impact load and repetitive load) is applied to the user, and this places a heavy burden on the user.

Therefore, in order to solve the above problems, the inventor of the present invention, for example, has one end locked to the upper ring of the upper end of the golf bag and the other end is the middle of the golf bag. 29, the shock absorber 1 shown in FIG. 29 is arranged between the upper ring and one end of the shoulder belt.

That is, the shock absorber 1 includes a cylindrical case 2 as shown in FIGS. 26A, 26B, and 26C, for example, on one end side and the other end side of the case 2 in the axial direction. The covers 3a and 3b are formed, respectively. The covers 3a and 3b have through holes 4a and 4b at substantially the center thereof. The connection part of case 2 and cover 3a, 3b has a screw-type connection structure by insert molding, for example. In the case 2, a tension coil spring 5 having a length direction is accommodated as a buffer. The tension coil spring 5 is an elastic member in which a force acts in a direction in which a plurality of spring steel wires wound with a constant inner diameter are brought into close contact with each other. In addition, a pair of hook portions 5 a and 5 b processed into a hook shape are formed at both end portions in the longitudinal direction of the tension coil spring 5.

Further, lead bars 6a and 6b are engaged with the pair of hook portions 5a and 5b. The lead bars 6a and 6b have long holes 7 and 7 on both sides in the axial direction. The pair of hook portions 5a and 5b are respectively engaged with the long holes 7 and 7 on one side in the axial direction of the lead bars 6a and 6b. The other end side in the axial direction of the lead bars 6a, 6b is connected to the cover 3a, so that the long holes 7, 7 on the other side in the axial direction of the lead bars 6a, 6b are exposed to the outside of the covers 3a, 3b, respectively. The through holes 4a and 4b of 3b are inserted. Further, connecting rings 8a and 8b such as double rings are attached to the long holes 7 and 7 of the lead bars 6a and 6b exposed to the outside of the covers 3a and 3b, respectively.

The shock absorber 1 is attached to the shoulder belt of the golf bag by attaching one connecting ring 8a to the upper ring of the golf bag and attaching the other connecting ring 8b to one end of the shoulder belt. . In this golf bag, the dynamic load due to the weight of the golf bag is mitigated by the buffering action of the shock absorber 1 disposed on the shoulder belt, and the load on the wrist, arm, shoulder, back, waist, elbow, knee, etc. of the user. Is reduced.

However, in this shock absorber 1, a tension coil spring 5 is formed as a shock absorber, and hook ends 5a, 5b are formed by processing end portions of spring steel wires at both ends of the tension coil spring 5. Is formed, and the formation of the hook portions 5a and 5b is accompanied by an abrupt shape change. Therefore, when a large dynamic load (impact load and repetitive load) is applied to the shock absorber 1, fatigue failure due to stress concentration occurs at the root portions of the hook portions 5 a and 5 b, and the root portions and the hook portions of the hook portions 5 a and 5 b. The engaging portion between the lead bars 6a and 6b may be damaged, and the cover 3a and 3b may also be damaged due to the impact at the time of the damage. Therefore, the shock absorber 1 cannot stably exhibit the shock absorbing function, and as a result, when the bag with the shock absorber 1 set is carried, it is applied to the user's hand, arm, shoulder, and back. There was a possibility that the burden could not be reduced.

Further, in the shock absorber 1, after the hook portions 5a, 5b of the tension coil spring 5 and the lead bars 6a, 6b are housed in the cylindrical case 2, the case 2 and the cover 3a are stored. , 3b are connected by screws, and further, the buffer 1 is assembled by attaching the lead bars 6a, 6b and the connecting rings 8a, 8b, so that it has a complicated and fragile assembly structure In addition, the assembling work takes time and effort.

Further, in this shock absorber 1, the hook portions 5a, 5b of the tension coil spring 5 are attached to the object to be attached via the lead bars 6a, 6b and the connecting rings 8a, 8b. In addition to increasing the space occupied by 5a, 5b and the lead bars 6a, 6b, on the other hand, in order to ensure a sufficient effective length related to the buffering operation of the tension coil spring 5 and to effectively exhibit the buffering function, Since the effective length of the tension coil spring 5 needs to be increased, the space for incorporating the tension coil spring 5 is inevitably increased. Therefore, in this shock absorber 1, the length of the case 2 becomes long, and the total length of the shock absorber 1 must be long. That is, with this shock absorber 1, it has been difficult to incorporate a shock absorber while ensuring an effective length for sufficiently exerting a shock absorbing function in a relatively short space.
Therefore, in this shock absorber 1, in addition to the golf bag, a hand bag type, a shoulder bag type, a backpack type, and a bag that combines two or more of them, for example, a Boston bag, a trunk, a travel basket, a sports bag, a rucksack It was unsuitable for use in business bags, suitcases, tool bags, shopping bags, etc.

Therefore, a main object of the present invention is to provide a bag cushioning device having a strong and simple assembly structure and capable of stably exhibiting a buffering function. It is to provide a compact bag cushion having a short target length. Still another object of the present invention is to provide a shock absorber for a bag that can be used as a self-supporting guiding tool for a golf bag in which a golf bag is simply placed in a desired position without being burdened on a user. Is to provide.

The present invention according to claim 1 is a bag shock absorber for use in a bag including a bag body, and a handle and / or a shoulder belt provided on the bag body and used to carry the bag body. A cylindrical case, a cylindrical support member that has a projecting edge on the outer peripheral surface and is assembled on one side in the axial direction inside the case, and is fitted into the support member so as to be displaceable in the axial direction of the case A guide rod whose one end side in the axial direction is directly or indirectly attached to the bag, and a coil spring disposed around the guide rod along the axial direction of the guide rod and receiving a compressive load in the length direction of the coil center line A pressing portion that is disposed on the other end side in the axial direction of the guide rod and that compresses the coil spring toward the support member when the case and the guide rod are relatively displaced in a direction away from each other; And a connecting portion that is assembled to be supported by the occlusal portion and is directly or indirectly attached to the bag. The supporting member is a compression direction of the coil spring as viewed in the axial direction of the guide rod. The bag cushioning device is characterized in that it is disposed in the bag.
According to the first aspect of the present invention, the bag has a load on the guide rod and the connecting portion of the shock absorber when the bag is carried via the handle and / or the shoulder belt. When acting, the case and the guide rod move relative to each other in the axial direction of the case. As a result, the pressing portion and the support member move so as to approach each other, and the coil spring is compressed between the support member side and the pressing portion to generate a spring reaction force of the coil spring. At this time, the burden on the user's wrist, arm, elbow, shoulder, back, waist, knee, and the like due to the dynamic load of the bag is absorbed by the spring reaction force due to the compression of the coil spring, and is reduced or reduced. Since the bag operates against the spring reaction force accompanying the compression of the coil spring, when the carrying operation is finished and the load applied to the handle and / or shoulder belt of the bag is removed, the case and the guide rod are moved. Relative movement in directions approaching each other returns to the initial state. That is, the bag returns to a stationary state before carrying the bag via the handle and / or the shoulder belt.
Since the guide rod is guided along the inner peripheral surface of the support member and smoothly and stably displaces in the axial direction of the case, it is difficult for lateral vibration and vibration to occur with respect to the shaft center. Furthermore, since the coil spring is compressed along the outer peripheral surface of the support member, it is difficult for lateral vibration and vibration with respect to the coil center line to occur, and as a result, the coil spring is prevented from coming into contact with and rubbing against the guide rod, Further, it is possible to prevent buckling when the coil spring is compressed, thereby protecting the coil spring.
That is, the support member has a function of protecting the guide rod and the coil spring by restricting the lateral vibration and vibration of the guide rod and the coil spring. Further, since the frictional resistance between the coil spring and the guide rod due to the compression of the coil spring is reduced, the coil spring is smoothly compressed.
On the other hand, since the connecting portion is assembled on the other side in the axial direction of the case so as to be supported by the occlusal portion, it is firmly assembled and is difficult to come out of the case. Therefore, when the bag is carried via the handle and / or the shoulder belt, even when a load of the bag acts on the guide rod and the connecting portion of the shock absorber, the connecting portion is difficult to come off from the bag.

According to the second aspect of the present invention, since it has the above-described structure, in particular, the guide rod, the coil spring, and the pressing portion are housed in one case in a state of being arranged side by side, It is possible to make a so-called twin type compact configuration. In this case, even if the buffer function obtained by a single coil spring having a predetermined length is replaced with, for example, a pair of two coil springs having a length that is half the length of the single coil spring, It is possible to maintain the initially set buffer function.
On the other hand, in a large and relatively heavy bag such as a golf bag, even if the length of the case is increased by adopting a coil spring with a long effective length, it does not feel much inconvenience, but a business bag etc. For medium-sized, small-sized bags that are relatively small in weight, an increase in the case length causes a problem and an excellent aesthetic point in order to obtain an unnecessarily cushioning function. is not.

The present invention according to claim 8 includes a golf bag body having a mouth portion through which a golf club is inserted and removed, and a handle and / or a shoulder belt provided on the golf bag body and used to carry the golf bag body. A golf bag shock absorber used for a golf bag, which has a cylindrical case, a cylindrical support member that has a protruding edge on the outer peripheral surface, and is assembled on one side in the axial direction within the case, and a case The guide rod is inserted into the support member so as to be displaceable in the axial direction, and one end side of the axial direction is directly or indirectly attached to the bag, and is arranged around the guide rod along the axial direction of the guide rod. A coil spring that receives a compressive load in the length direction of the coil center line, and a direction in which the case and the guide rod are separated from each other, disposed on the other end side in the axial direction of the guide rod A press part that compresses the coil spring toward the support member when relatively displaced, and a connection that is assembled to the other side in the axial direction of the case so as to be supported by the occlusal part and is directly or indirectly attached to the bag The support member is disposed in the compression direction of the coil spring as viewed in the axial direction of the guide rod, and the connecting portion is detachably attached directly or indirectly to the mouth portion or the vicinity of the mouth portion of the golf bag, A golf bag shock absorber that assists in placing a golf bag body in a desired position in a self-standing state.
According to the eighth aspect of the present invention, since the golf bag has the above-described configuration, when the golf bag is made to stand on its own from a state where the handle of the golf bag is gripped or a shoulder belt is hung on the shoulder, The golf bag can be made self-supporting by gripping the outer peripheral surface of the case portion of the shock absorber of the golf bag and rotating the golf bag in the direction of self-supporting around the shock absorber. At this time, since the shock absorber of the golf bag, which is a mechanical fulcrum of the rotating golf bag, is attached to the mouth of the golf bag or the vicinity of the mouth, that is, above the center of the golf bag in the height direction, For example, the distance from the lower end of the golf bag to the buffer serving as the mechanical fulcrum is longer than when the buffer is attached to the center in the height direction of the golf bag or below the center, It is possible to increase the rotational moment when the golf bag is rotated in the direction of self-supporting. Therefore, the golf bag can be rotated relatively easily, and the golf bag can be easily made independent at a desired place.
On the other hand, like a conventional golf bag (for example, refer to Patent Document 1), the force of the rotational moment is added, so that the total weight of the golf bag becomes a heavy load, and the user is instantaneously affected. Although it is feared that a considerable burden is applied, in the present invention according to claim 8, in particular, since the shock absorber of the golf bag includes the coil spring, it is used instantaneously due to the buffer action of the coil spring. It is possible to absorb and relax the dynamic load (including impact load and repeated load) applied to the person. Therefore, as in the prior art, it is possible to greatly reduce the burden on the user's wrist, elbow, shoulder, waist, knee and the like due to the dynamic load. In other words, the golf bag can be easily placed in a desired position without placing a burden on the user.
Further, in the present invention according to claim 8, when the golf bag is lifted by holding the golf bag handle instantaneously on the spot in order to carry the golf bag from the self-supporting state, the shoulder belt is attached to the shoulder. As described above, when the golf bag is lifted by suspending the golf bag, or when the shoulder belt is hung on the shoulder, the golf bag cushioning device is used in the same manner as described above. Due to the buffering action of the coil spring, it is possible to instantly relieve the large dynamic load on the wrist, shoulder, waist, elbow, knee, etc. of the user and greatly reduce the burden on the user. .
Further, in the present invention according to claim 8, when the user makes the golf bag self-supporting from the state of carrying the golf bag, or when lifting the golf bag from the state in which the golf bag is self-standing, These operations can be performed by gripping the case outer peripheral surface (gripping portion) of the shock absorber of the golf bag, and using the grip portion of the shock absorber case as a base point of the motion. In other words, since the shock absorber of the golf bag is detachably attached to the mouth portion of the golf bag or in the vicinity of the mouth portion, the mouth portion of the golf bag faces substantially upward in each of the operations described above. It is hold | maintained to become an aspect. Therefore, according to the eighth aspect of the present invention, when a golf bag containing a large number of golf clubs or the like is lifted as in a conventional golf bag (see, for example, Patent Document 1), The golf club does not suddenly jump out of the mouth.
Furthermore, in the present invention according to claim 8, since the connecting portion can be detachably attached directly or indirectly to the mouth portion or the vicinity of the mouth portion of the golf bag, the shock absorber is attached to the golf bag. Can be retrofitted to the mouth part or the vicinity of the mouth part, and the degree of freedom is high in the selection of the place to be retrofitted.

Therefore, according to the present invention according to claim 9, the shock absorber and the shoulder belt can be disposed on the same straight line at a position close to each other, for example, from a state in which the shoulder belt is hung on the shoulder. The golf bag can be easily made independent by quickly grasping the outer peripheral surface (gripping portion) of the case of the shock absorber with the shoulder side hand.
For example, the golf bag is carried with the shoulder belt on the shoulder (the golf bag main body is substantially parallel to the floor surface or the ground or is turned sideways with a predetermined inclination, for example, see FIG. 8). When lowering, the user grasps the handle of the golf bag with one hand, removes the shoulder belt from the shoulder, and grasps the outer peripheral surface (gripping part) of the case of the shock absorber with the other hand, With the gripping portion of the shock absorber as a mechanical fulcrum (rotation center), the lower end side of the golf bag body can be easily rotated in a direction to be self-supporting on the floor or the ground (for example, FIG. 8, FIG. 9 and See FIG. At this time, the gripping portion of the shock absorber serving as a fulcrum (rotation center) when rotating the golf bag main body in a self-supporting direction is above the center in the height direction of the golf bag main body, that is, the mouth portion of the golf bag main body. Or since it arrange | positions in the mouth part vicinity, the distance between the lower end part of a golf bag main body and a fulcrum becomes long, and the magnitude | size of a rotational moment becomes large (for example, refer FIG. 11). Therefore, it is possible to easily rotate the golf bag main body and quickly stand on the floor or the ground.
Further, according to the present invention of claim 9, as described above, the user can easily make the golf bag body self-supporting by the cooperative action of the handle and the shock absorber of the golf bag. However, for example, when the golf bag is carried with the shoulder belt on the shoulder (see, for example, FIG. 8), the user removes the shoulder belt from the shoulder and moves the shoulder bag with one hand. By grasping the outer peripheral surface (gripping portion) of the case of the golf bag cushioning device, the gripping portion of the cushioning device is used as a mechanical fulcrum (rotation center), and the lower end side of the golf bag body is easily placed on the floor or ground. It is possible to rotate in a direction to make it stand on its own (see, for example, FIGS. 8 and 10).

The connecting portion is directly or indirectly attached to the bag body of the bag, so that the shoulder belt can be hung on the shoulder and the bag can be carried.
When carrying the bag with the shoulder belt attached, if the load of the bag acts on the guide rod and the connecting portion of the shock absorber, the case and the guide rod move relative to each other in the axial direction of the case. . As a result, the pressing portion and the support member move so as to approach each other, and the coil spring is compressed between the support member side and the pressing portion to generate a spring reaction force of the coil spring. At this time, the burden on the user's wrist, arm, elbow, shoulder, back, waist, knee, and the like due to the dynamic load of the bag is absorbed by the spring reaction force due to the compression of the coil spring, and is reduced or reduced. Since the bag operates against the spring reaction force associated with the compression of the coil spring, when the carrying operation is completed and the bag load on the shoulder belt is removed, the case and the guide rod move toward each other. Move relative to return to the initial state. That is, it returns to the stationary state before carrying the bag through the shoulder belt.
Since the guide rod is guided along the inner peripheral surface of the support member and smoothly and stably displaces in the axial direction of the case, it is difficult for lateral vibration and vibration to occur with respect to the shaft center. Furthermore, since the coil spring is compressed along the outer peripheral surface of the support member, it is difficult for lateral vibration and vibration with respect to the coil center line to occur, and as a result, the coil spring is prevented from coming into contact with and rubbing against the guide rod, Further, it is possible to prevent buckling when the coil spring is compressed, thereby protecting the coil spring.
That is, the support member has a function of protecting the guide rod and the coil spring by restricting the lateral vibration and vibration of the guide rod and the coil spring. Further, since the frictional resistance between the coil spring and the guide rod due to the compression of the coil spring is reduced, the coil spring is smoothly compressed.
On the other hand, since the connecting portion is assembled on the other side in the axial direction of the case so as to be supported by the occlusal portion, it is firmly assembled and is difficult to come out of the case. For this reason, when the bag is carried via the shoulder belt, even when a load of the bag acts on the guide rod and the connecting portion of the shock absorber, the connecting portion is difficult to come off from the bag.
In the above-described shoulder belt, the connecting portion is directly or indirectly attached to one end and / or the other end in the length direction of the shoulder belt, and the guide rod attaching portion is directly or indirectly attached to the bag body of the bag. By being attached indirectly, it is also possible to carry the bag with the shoulder belt on the shoulder.

According to the present invention, it is possible to provide a cushioning device for a bag having a strong and simple assembly structure and capable of stably exhibiting a buffering function, and a compact having a relatively short length. It is to provide a bag cushion. Furthermore, according to the present invention, there is provided a bag cushioning device that can be used as a self-supporting guiding device for a golf bag that is arranged in a state where the golf bag is easily self-supported at a desired place without imposing a burden on the user. Can be provided.

The bag cushion according to this embodiment is a bag cushion used in a bag including a bag body and a handle and / or a shoulder belt provided on the bag body and used to carry the bag body. . The structure of the cushion of the bag will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, a bag cushion 10 according to this embodiment includes a cylindrical case 12 formed of an elastic material such as TRP (thermoplastic rubber). The case 12 has an integrated structure in which a pair of two halves 12A and 12B having substantially the same shape, which are divided along the axial center line of the case 12, are abutted and joined. On the outer peripheral surface of the body portion 14 of the case 12, a covering portion 16 serving as a grip portion is formed. In the following description, the covering portion 16 will be read as “gripping portion 16” for convenience.
A large number of protrusions 18 are arranged on the outer surface of the gripping part 16 at intervals. A large number of protrusions 18 are formed by embossing or the like. For this reason, when the user grips the grip 16, it is easy to hold and fit the hand in terms of the material surface of the grip 16, and the protrusion 18 of the grip 16 is formed. It has an anti-slip function. The case 12 is not limited to TRP (thermoplastic rubber), and may be formed of other rubber and elastic materials such as silicone resin. Further, even if the case 12 is formed of a material having rigidity such as a metal material, a woody material, or a hard resin material, a sheet-like material or cloth cloth made of an elastic material on the outer surface (exposed surface) of the case 12 May be configured to form the gripping portion 16.

Next, the main members assembled in the case 12 and the arrangement thereof will be described below with reference to FIGS. 3, 4, 5, and 6, for example.
For example, as shown in FIGS. 3 and 5, for example, a cylindrical support member 20 is disposed in the case 12 on one side of the case 12 in the axial direction. The support member 20 has a projecting edge portion 22 serving as a flange on the outer peripheral surface thereof, and is assembled to one side in the axial direction in the case 12. The protrusion 22 extends in the radial direction of the support member 20 and is formed in an annular shape, for example. For example, a guide rod 24 having a circular cross section is inserted into the support member 20.

The guide rod 24 is movable (displaceable) along the axial direction of the case 12, and one end side of the guide rod 24 in the axial direction is supported by the support member 20. An attachment portion 26 made of, for example, an eye is formed at one end portion of the guide rod 24 in the axial direction. As shown in FIGS. 1 and 5, the mounting portion 26 is exposed to the outside of the case from one end side in the axial direction of the case 12, and is directly or indirectly a bag (not shown in FIGS. 1 to 3). ) Is attached. In this case, the case 12 has an insertion hole 27 on one end side in the axial direction so that the base portion side of the mounting portion 26, that is, one end portion in the axial direction of the guide rod 24 is exposed from the case 12. Yes.
Further, at the other end in the axial direction of the guide rod 24, for example, as shown in FIG. 5, a male thread surface 28 is formed with a predetermined length. The male screw surface 28 is screwed with a female screw surface 38 of a fastening member 36 described later. For example, a long bolt with an eye may be used for the guide rod 24.
In the bag cushion 10 according to this embodiment, the mounting portion 26 of the guide rod 24 is directly or indirectly between the bag body and the handle and / or shoulder belt, on the handle and / or shoulder belt side. It is attached.

Further, as shown in FIGS. 3 and 5, for example, a cylindrical compression coil spring 30 is disposed around the guide rod 24 as a coil spring that receives a compressive load in the length direction of the coil center line. The compression coil spring 30 is disposed along the axial direction of the guide rod 24. A pressing portion 32 is detachably attached to the other end side of the guide rod 24 in the axial direction. For example, as shown in FIG. 6, the pressing portion 32 compresses the compression coil spring 30 toward the above-described support member 20 when the case 12 and the guide rod 24 are relatively displaced in a direction away from each other. .

The pressing portion 32 includes an annular ring member 34, for example. The ring member 34 is formed by a washer, for example. As shown in FIGS. 3 and 5, the ring member 34 is detachably disposed at the other end portion in the axial direction of the guide rod 24 so as to face one end portion in the length direction of the compression coil spring 30. The pressing portion 32 includes a fastening member 36 that is fastened to the other end portion of the guide rod 24 in the axial direction. The fastening member 36 has, for example, a female thread surface 38 formed on the inner peripheral surface thereof. The fastening member 36 is fastened to the other end portion of the guide rod 24 in the axial direction. The fastening member 36 is formed of a nut, for example. The fastening member 36 is detachably fastened to the male thread surface 28 of the guide rod 24. The fastening member 36 compresses the compression coil spring 30 via the ring member 34 when the case 12 and the guide rod 24 are relatively moved in directions away from each other. In the bag cushion 10, for example, as shown in FIG. 6, the support member 20 described above is disposed in the compression direction of the compression coil spring 30 when viewed in the axial direction of the guide rod 24.

On the other hand, a connecting portion 40 is disposed on the other side of the case 12 in the axial direction. The connecting portion 40 is assembled to the case 12 so as to be supported by the occlusal portion 42, and is directly or indirectly attached to a bag (not shown in FIGS. 1 to 5). As the connection part 40, connection metal fittings, such as D can, a lion can, a round can, and a square can, may be used suitably.
In the bag cushion 10 of this embodiment, the connecting portion 40 is directly or indirectly attached to the bag body side between the bag body and the handle and / or shoulder belt.

As shown in FIGS. 2, 3, and 4, the occlusal portion 42 is disposed on the other end side in the axial direction in the case 12 in a direction orthogonal to the axial center line of the case 12, for example, two rows of occlusions Columns 44 and 46 are included. The two occlusion rows 44 and 46 are arranged at intervals in the axial direction in the case 12. The two occlusion rows 44 and 46 are each formed by engaging a plurality of occlusal irregularities 48 with each other.
In this case, of the two occlusion rows 44 and 46, the occlusion row 44 disposed at a position closest to the other end side in the axial direction in the case 12 is formed as an outer occlusion row. Therefore, this occlusion row 44 is referred to as an outer occlusion row 44 for convenience. In the vicinity of the outer occlusion row 44 and in the axial direction of the case 12, an engaging portion 50 to which the connecting portion 40 is attached is disposed at a position closer to the inner side of the case 12. The connecting portion 40 is engaged with the engaging portion 50 and is supported by the outer occlusion row 44.

On the other hand, as shown in FIGS. 3 and 4, for example, the case 12 includes two halves 12A and 12B having a substantially semicircular cross section and the same shape. The two halves 12A and 12B have their open sides butted together, and are welded together by an appropriate method such as ultrasonic welding, and are integrally joined. Thus, the two halves 12A and 12B are formed as a substantially cylindrical case 12. As shown in FIGS. 4A and 4B, each of the two halves 12A and 12B includes half halves accommodating portions 52A and 52B having a rectangular shape in plan view and a semicircular cross section. When the case 12 is integrated, the case 12 has a substantially cylindrical storage portion 52 by the half- body storage portions 52A and 52B.

Therefore, the internal structure of the case 12 to which the main member described above is assembled will be described below with reference to FIGS. 3, 4, 5, and the like.
The two halves 12A and 12B of the case 12 include, for example, one half housing portion 52A having a substantially semicircular cross section and a substantially rectangular shape in plan view from one side to the other side of the intermediate portion in the axial direction of the case 12. 52B is provided. In the two half- body storage portions 52A and 52B, a portion 54 extending from the other end in the axial direction of the guide rod 24 to the middle portion, a portion 56 extending from one end in the axial direction to the middle portion of the support member 20, and a compression A portion 58 extending from one end to the other end of the coil spring 30 in the length direction, the ring member 34 of the pressing portion 32, and the fastening member 36 are housed.

The two halves 12 </ b> A and 12 </ b> B of the case 12 are engaged with a fitting recess 60 into which at least an intermediate portion in the axial direction of the support member 20 is fitted, and a protruding edge 22 of the support member 20. And a locking recess 62. The fitting recess 60 has a substantially semicircular cross section corresponding to the cross sectional shape divided along the axial center line of the support member 20. Similarly, the locking recess 62 is formed in a substantially semicircular cross section corresponding to the cross sectional shape divided along the axial center line of the protruding edge portion 22.
Furthermore, the storage part 52, the fitting recessed part 60, and the latching recessed part 62 are connected.
The compression coil spring 30 is disposed between one main surface of the ring member 34 of the pressing portion 32 and the surface 64 of the boundary portion between the storage portion 52 and the fitting recess 60 when viewed in the axial direction of the case 12. .

In the bag shock absorber 10 according to this embodiment, for example, the other half body in which the main member described above is assembled to the half body storage portion 52A of one half body 12A and further includes the half body storage portion 52B. 12B is butted over one half 12A. After that, the two halves 12A and 12B are welded by an appropriate method such as ultrasonic welding, and are integrally joined, whereby the bag cushion 10 is obtained.

FIG. 7 is a view showing an example of a use state of the shock absorber shown in FIG. 1 (A) and FIG. 1 (B), and in particular, a perspective view showing an example of a state in which the shock absorber is attached to a golf bag. is there. FIG. 8 is a perspective view showing an example of a state where the golf bag shown in FIG. 7 is carried on the shoulder.
The bag cushion 10 described above can be used, for example, as a self-supporting guidance tool that is attached to an appropriate portion of a golf bag and assists in placing the golf bag in a desired position in a self-supporting state. Therefore, an example of a golf bag to which the buffer 10 of the bag can be attached will be described below with reference to FIG. FIG. 7 is a perspective view showing an example of a state in which the bag cushion 10 shown in FIGS. 1 to 6 is attached to the golf bag 100.
Golf bag 100 includes a golf bag body 102. The golf bag body 102 has a mouth portion 104 </ b> A reinforced by a mouth frame portion 104 at the upper end portion in the height direction. A large number of golf clubs (not shown) are accommodated in the golf bag main body 102 through the mouth portion 104A. The golf bag body 102 is provided with a handle 106 on one side surface of the golf bag body 102 so as to be convenient when carrying the golf bag body 102. The handle 106 is formed, for example, in a C shape with a plastic material, and is disposed on the upper portion of the golf bag body 102 in the height direction. In this case, one end portion of the handle 106 is attached to the mouth frame portion 104 via the attachment member 108, and the other end portion is attached to an upper portion in the height direction of one side surface of the golf bag main body 102. .

Further, a shoulder belt 110 is attached to the golf bag main body 102 so as to be convenient when the golf bag main body 102 is carried on the shoulder. The shoulder belt 110 has one end portion in the longitudinal direction attached to an intermediate portion in the height direction of one side surface of the golf bag main body 102 via an appropriate connecting member, and the other end portion in the longitudinal direction is attached to the shoulder belt 110. It is attached to the attachment member 108 via the above-described bag cushion 10 and an appropriate connecting member.
That is, one end portion in the longitudinal direction of the shoulder belt 110 is provided at an intermediate portion in the height direction of one side surface of the golf bag main body 102 through an appropriate connecting member such as the D can 112, the lever can 114, and the D can 116. The attachment member 118 is detachably connected. Further, the other end portion of the shoulder belt 110 in the longitudinal direction is connected to the attachment portion 26 of the buffer 10 of the bag via an appropriate connecting member such as the D can 120 and the lever can 122. Further, the connecting portion 40 of the bag buffer 10 is detachably connected to a D can 126 provided on the attaching member 108 of the golf bag main body 102 via connecting members such as a lever can 123 and a carabiner 124. Yes.
In addition to the D cans and the cocoon cans, the connecting member is not limited to a round can (ring can), a square can (hand can), a triangular can, a C can, a double can (double ring), etc. In addition to the carabiner, other appropriate connecting members such as a swivel, a monkey can, a rotating can, a lever can, a universal joint, and a ball joint may be employed.

Since the golf bag 100 shown in FIG. 7 has the above-described configuration, the bag is provided between the other end of the shoulder belt 110 and the vicinity of the mouth 104A of the golf bag 100, that is, at the upper end of the shoulder belt 110. The shock absorber 10 can be detachably attached. Therefore, in this golf bag 100, it is possible to arrange the shock absorber 10 and the shoulder belt 110 of the bag at positions close to each other and on the same straight line. For example, the shoulder belt 110 is hung on the shoulder. From this state, the golf bag 100 can be easily made independent by quickly grasping the grasping portion 16 of the shock absorber 10 of the bag with the shoulder side hand.

In the golf bag 100 shown in FIG. 7, the connecting portion 40 of the shock absorber 10 and the vicinity of the mouth portion 104 </ b> A of the golf bag 100 can be easily connected via the lever can 123 and the carabiner 124. The attachment portion 26 of the shock absorber 10 and the other end of the shoulder belt 110 can be easily connected via the lever can 122. That is, in the golf bag 100, in particular, between the vicinity of the mouth 104 </ b> A of the golf bag 100 and the other end of the shoulder belt 110 via the connecting portion 40 of the shock absorber 10 and the attachment portion 26 of the shock absorber 10. The buffer 10 of the bag can be easily attached and detached.

In the golf bag 100 shown in FIG. 7, for example, when the golf bag 100 is carried with the shoulder belt 110 on the shoulder, that is, as shown in FIG. 8, the golf bag main body 102 is almost parallel to the floor or the ground. In the case of lowering from a horizontal position with a predetermined inclination, the user removes the shoulder belt 110 from the shoulder and grips the handle 106 with one hand, as shown in FIG. By gripping the gripping portion 16 of the cushioning device 10 of the bag, the gripping portion 16 of the cushioning device 10 is used as a mechanical fulcrum (rotation center), and the lower end side of the golf bag main body 102 can easily stand on the floor or the ground. It can be rotated in the direction of At this time, the gripping portion 16 of the shock absorber 10 serving as a fulcrum (rotation center) when rotating the golf bag main body 102 in a self-supporting direction is above the center of the golf bag main body 102 in the height direction, that is, the golf bag. Since it is disposed in the vicinity of the mouth frame portion 104 of the main body 102, as shown in FIG. 11, the distance L between the lower end portion of the golf bag main body 102 and the fulcrum O (the gripping portion 16 of the shock absorber 10) becomes long and rotates. The magnitude of the moment increases. Therefore, the golf bag main body 102 can be easily rotated to quickly stand on the floor or the ground.

In this case, like the conventional golf bag (for example, refer patent document 1), when the force of a rotational moment is added, the total weight of the golf bag 100 becomes a big load, and it is instantaneously a user. However, in the golf bag 100 shown in FIG. 7, the gripping portion 16 of the bag cushion 10 has the compression coil spring 30. By the buffering action utilizing the reaction force (elastic force) of the spring, it is possible to absorb and relax the dynamic load (impact load and repeated load) applied to the user instantaneously. Therefore, as in the prior art, the burden on the wrist, elbow, shoulder, waist, knee, etc. of the user due to this dynamic load can be greatly reduced.
Therefore, according to the golf bag 100 shown in FIG. 7, it is possible to simply place the golf bag 100 in a desired position in a self-supporting manner without imposing a burden on the user.

According to the inventor's experiment, when a load is applied to the golf bag 100 shown in FIG. 7, in the golf bag 100 to which the shock absorber 10 of this bag is attached, the conventional shock absorber 10 is not attached. It has been found that the load applied to the golf bag 100 is significantly reduced by the buffering action of the compression coil spring 30 as compared with the golf bag.
In this case, as a sample in which a weight W having a predetermined weight (98N and 196N) is attached to a load tester that detects a load by a load cell, the bag cushioning device 10 is hung and the vertical direction of 500 mm / second is lowered from a stationary state. The load applied to the load cell was measured by moving 30 mm at a constant speed and vibrating. In this case, for the comparison test, the load value was measured when the buffer 10 of the bag was attached and when the buffer 10 was not attached.
In this test, as shown in FIGS. 12 and 13, an electrodynamic tester E3000 manufactured by Instron was used. FIG. 15 and FIG. 16 are graphs showing the relationship between “test elapsed time (transition time) and load cell detected load value”. 15 is a graph when the weight W has a weight of 98N, and FIG. 16 is a graph when the weight W has a weight of 196N.
As shown in the graph of FIG. 15, when the weight W is 98 N and the bag buffer 10 is not attached, the instantaneous load is about 680 N at maximum. When the shock absorber 10 is attached, the maximum is about 440N, which shows that it is greatly reduced. Similarly, as shown in the graph of FIG. 16, when the weight W is 196 N and the bag buffer 10 is not attached, the load applied instantaneously is approximately 1010 N at maximum. On the other hand, when the shock absorber 10 is attached, the maximum is about 710N, which shows that it is greatly reduced.

Therefore, in the golf bag 100 shown in FIG. 7, when the golf bag body 102 is made independent from a state in which the handle 106 is gripped or the shoulder belt 110 is hung on the shoulder, or from the state in which the golf bag is made independent. When the golf bag 100 is lifted by putting the shoulder belt 110 on the shoulder instantaneously on the spot, or when the golf bag 100 is lifted by holding the handle 106, and further, with the shoulder belt 110 hung on the shoulder, When walking on undulations on stairs or golf courses, a large dynamic load on the wrist, shoulder, waist, elbow, knee, etc. of the user is momentarily applied to the compression coil spring 30 of the cushion 10 of this bag. It is possible to relieve the burden on the user by buffering action.

According to the golf bag 100 shown in FIG. 7, as described above, the user can easily make the golf bag main body 102 independent by the cooperative action of the handle 106 and the shock absorber 10. For example, when the golf bag 100 is carried with the shoulder belt 110 on the shoulder (see, for example, FIG. 8), the user removes the shoulder belt 110 from the shoulder and moves the golf bag 100 with one hand. By gripping the grip 16 of the shock absorber 10, the grip 16 of the self-supporting guiding tool 10 is used as a mechanical fulcrum (rotation center), and the direction in which the lower end side of the golf bag body 102 can easily stand on the floor or the ground. (For example, see the state shown in FIG. 10 from the state shown in FIG. 8).

1 to 6 is attached to a golf bag, the attachment device for connecting the bag cushion 10 to the shoulder belt 110 (for example, shown in FIGS. 7 to 10) is not used. It is also possible to attach the bag cushion 10 to the mouth 104A or the vicinity of the mouth 104A in a detachable manner (not shown). One of the connecting portion 40 and the attachment portion 26 of the bag cushion 10 can be detachably attached to, for example, the mouth portion 104A of the golf bag 100 shown in FIG. 7 or the vicinity of the mouth portion 104A. Therefore, it is possible to freely attach the cushion 10 of the bag to the mouth 104A of the golf bag 100 or in the vicinity of the mouth 104A, and to have a high degree of freedom in selecting the place to be attached. Is possible.
When the golf bag body 102 is to be self-supported from the state in which the handle 106 of the golf bag 106 is gripped or the shoulder belt 110 is hung on the shoulder, the user can perform the same operation as in the case of the golf bag 100 shown in FIG. The golf bag 100 can be made self-supporting by gripping the grip 16 of the bag cushioning device 10 and rotating the golf bag main body 102 around the cushioning device 10 in a self-supporting direction.

In this case, like the conventional golf bag (for example, refer patent document 1), when the force of a rotational moment is added, the total weight of the golf bag 100 becomes a big load, and it is instantaneously a user. However, as in the case of the golf bag 100 shown in FIGS. 7 to 10, the movement that is instantaneously applied to the user by the buffering action of the compression coil spring 30 of the shock absorber 10 is feared. The load can be absorbed and relaxed. Therefore, as in the prior art, the burden on the wrist, elbow, shoulder, waist, knee, etc. of the user due to this dynamic load can be greatly reduced.

In each of the golf bags 100 described above, when the user makes the golf bag self-supporting from the state in which the golf bag 100 is carried, or when the golf bag 100 is lifted from the state in which the golf bag 100 is erected, In the operation, by grasping the grip 16 of the shock absorber 10, the grip 16 of the shock absorber 10 can be used as a base point of the motion. In this case, since the shock absorber 10 is detachably attached in the vicinity of the mouth 104A of the golf bag 100, when the above-described operation is performed, the golf bag 100 has an aspect in which the mouth 104A faces substantially upward. To be held. Therefore, according to the golf bag 100 shown in FIG. 7, when a golf bag containing a large number of golf clubs or the like is lifted as in a conventional golf bag (see, for example, Patent Document 1), The golf club does not suddenly jump out of the mouth.

FIG. 16 is a view showing another example of the embodiment of the shock absorber for the bag according to the present invention, and in particular, is a plan view of the main part showing the internal structure thereof. FIG. 17 is a plan view of a principal part showing a compression state of the compression coil spring when a load is applied in the shock absorber shown in FIG. 16.
Compared to the bag cushion 10 shown in FIGS. 1 to 6, for example, the number and combination of the coil springs incorporated in the case 12 are different in the bag cushion 10. That is, in the bag shock absorber 10 shown in FIGS. 1 to 6, one compression coil spring 30 is arranged in the case 12, but in the bag shock absorber 10 shown in FIGS. 16 and 17, one compression coil is provided. In addition to the spring 30, for example, one conical spring 66 is arranged vertically in the axial direction of the guide rod 24. In this case, for example, another annular ring member 68 is detachably disposed in the central portion of the guide rod 24 in the axial direction, and the ring member 34 disposed at the other axial end portion of the guide rod 24 and the like. A conical spring 66 is disposed between the ring member 68 and the ring member 68.

In this way, in the shock absorber 10 of this bag in which the compression coil spring 30 and the conical spring 66 are combined in series in the axial direction of the guide rod 24, for example, in the golf bag 100 shown in FIGS. In other words, the load of the golf bag bag 100 applied to the shock absorber 10 acts as a shock absorbing action of the compression coil spring 30 via the shock absorbing action of the conical spring 66. In this case, when the spring of the conical spring 66 is first compressed by the load, the line-to-line contact starts from the larger coil diameter, and thereafter the line-to-line contact sequentially proceeds. The spring action is lost at the part where the line contacts. That is, the conical spring 66 has a non-linear spring characteristic that the spring becomes harder as the line-to-line contact proceeds. Then, since the buffering action of the compression coil spring 30 works following the buffering action of the conical spring 66, the burden on the user can be eased smoothly. Further, since the conical spring 66 can reduce the contact height of the coil during compression, the axial length of the case 12 can be further reduced in terms of space.
Therefore, according to the shock absorber 10 of the bag shown in FIGS. 16 and 17, it is possible to deal with various types of bags having different loads.

FIG. 18 is an exploded perspective view of a main part showing still another example of the embodiment of the bag cushion according to the present invention. The shock absorber 10 of the bag is different from the shock absorber 10 of the bag shown in FIGS. 1 to 6 in particular in the mounting portion disposed at one end portion of the guide rod 24 in the axial direction. That is, in the shock absorber 10 of the bag shown in FIGS. 1 to 6, the mounting portion 26 is formed with an eye. However, for example, a double ring 70 is used as the mounting portion 26 in the shock absorber 10 of the bag shown in FIG. It has been. In this case, the guide rod 24 has a long hole 72 at one end in the axial direction, and the double ring 70 is engaged with the long hole 72.

FIG. 19 is a diagram showing another example of the use state of the shock absorber shown in FIG. 1 (A) and FIG. It is a perspective view.

Further, on both sides of the bag body 202 in the length direction, connecting tools 208 such as D-cans are disposed. Further, a shoulder belt 210 can be detachably attached to the bag body 200. The shoulder belt 210 has a connecting tool 212 such as a round can at both ends thereof, and a connecting tool 214 such as a lever can be attached to the connecting tool 212. The shoulder belt 210 is detachably attached to the bag body 202 by engaging the connection tool 214 with the connection tool 208 of the bag body 202. In this case, in the bag cushion 10 according to the present embodiment, the connecting portion 40 is detachably attached to one connecting member 208 of the bag body 202, and the attaching portion 26 is a connecting tool on one end side of the shoulder belt 210. 214 is detachably attached.

FIG. FIG. 21 is an exploded perspective view of the shock absorber of the bag shown in FIGS. 20 (A) and 20 (B). FIG. 22 is a view for explaining mainly the arrangement of the guide rod, the support member, the compression coil spring, and the pressing portion (ring member, fastening member) of the shock absorber of the bag shown in FIGS. 20 (A) and 20 (B). It is a disassembled perspective view. FIG. 23 is a plan view of a principal part showing a compression state of the compression coil spring when a load is applied in the shock absorber shown in FIGS. 20 (A), 20 (B) and FIG. 21.
Compared with the bag cushioning device 10 shown in FIGS. 1 to 6, for example, the bag cushioning device 10 has a number of members such as a support member, a guide rod, a compression coil spring, and a pressing portion assembled in the case. And their arrangement is different. The bag cushion 10 shown in FIGS. 1 to 6 has a structure in which a single support member 20, a guide rod 24, a compression coil spring 30, and a pressing portion 32 are incorporated in one case 12, respectively. On the other hand, in the bag shock absorber 10 shown in FIGS. 20 to 23, the support member 20, the guide rod, the compression coil spring, and the pressing portion are housed in one case in a side-by-side arrangement. It is different in that it has a twin type compact configuration.

That is, in the shock absorber 10 of the bag shown in FIGS. 20 to 23, the case 12 includes, for example, two storage portions 74 and 76 that are arranged side by side with an interval, as shown in FIG. The two storage portions 74 and 76 are configured by half- body storage portions 74A and 74B and half- body storage portions 76A and 76B, respectively. The half body storage portions 74A and 74B and the half body storage portions 76A and 76B are arranged such that the storage portions 74 and 76 are partitioned by a partition portion 77, respectively. In addition, in the axial direction (length direction) in the case 12, for example, two cylindrical support members 78 </ b> A and 78 </ b> B are arranged side by side in the width direction of the case 12 with an interval. Protrusions 80A and 80B are formed on the outer peripheral surfaces of the two support members 78A and 78B, respectively. The two projecting edge portions 80A and 80B are connected by a support member connecting portion 82, and have an integrated structure, for example, in an oval shape.

Moreover, two guide rods 84A and 84B are assembled to the two storage portions 74 and 76. That is, the two guide rods 84A and 84B are arranged side by side at a distance. The two guide rods 84A and 84B are connected at one end in the axial direction by a rod connecting portion 86 having a substantially arc shape, for example. The two guide rods 84A and 84B and the rod connecting portion 86 are integrally formed and constitute, for example, a substantially U-shaped guide rod 84. The rod connecting portion 86 of the guide rod 84 is assembled to the case 12 so as to be exposed from one end side in the axial direction of the case 12. That is, the rod connecting part 86 has a function as an attaching part. Hereinafter, the rod connecting portion 86 may be referred to as an “attachment portion” for convenience.

In this case, for example, as shown in FIG. 21, the half- body storage portions 74A and 74B and the half- body storage portions 76A and 76B are arranged at the ends of the two guide rods 84A and 84B at one end in the axial direction (length direction). In order to expose the rod connecting portion 86 on the other end side in the direction, for example, insertion concave portions 85A and 85B each having a semicircular cross section are provided. By inserting the half-body accommodating portions 74A and 74B and the half-body accommodating portions 76A and 76B vertically, the insertion recesses 85A and 85B are connected to the rod connecting portion 86 on the other end side in the axial direction of the two guide rods 84A and 84B. It becomes insertion hole 87A, 87B for exposing.

Further, in the case 12, for example, two compression coil springs 88A and 88B are disposed around the two guide rods 84A and 84B along the axial direction of the two guide rods 84A and 84B. In the case 12, two pressing portions 90A and 90B for compressing the two compression coil springs 88A and 88B toward the two support members 78A and 78B are disposed. The two pressing portions 90A, 90B have two ring members 92A, 92B and two fastening members 94A, 94.

Further, the other end side in the axial direction in the case 12A and the case 12B is disposed in a direction orthogonal to the axial center line of the case 12, as shown in FIGS. For example, it includes an occlusal portion 96 having two occlusion rows 96A and 96B. The two occlusion rows 96A and 96B are arranged in the case 12A and the case 12B with an interval in the axial direction. The two occlusion rows 96A and 96B are formed by engaging a plurality of occlusal uneven portions 97A and 97B with each other. In this case, of the two rows 96A and 96B, the occlusion row 96A arranged at the position closest to the other end side in the axial direction in the case 12A and the case 12B is formed as an outer occlusion row. Further, in the vicinity of each outer occlusion row 96A and in the axial direction of the cases 12A and 12B, at the positions closer to the inner sides of the cases 12A and 12B, the engaging portions 95A, 95B is provided. The connecting portion 40 is engaged with the engaging portions 95A and 95B and is firmly supported by the outer occlusion row 96A.

FIG. 24 is a view showing another example of the use state of the shock absorber shown in FIGS. 20 (A), 20 (B) and FIG. 21, and FIG. FIG. 24B is a perspective view of the shock absorber.
The Boston bag 300 includes a bag body 302. A hand handle 304 is disposed on the upper portion of the bag body 302. In addition, a connecting tool 308 such as a D-can is disposed on each of the upper portions of the bag body 302 in the length direction. Furthermore, a shoulder belt 310 can be detachably attached to the bag body 302. The shoulder belt 310 has a connector 312 such as a lever can attached to both ends thereof. The shoulder belt 310 is detachably attached to the bag body 302 by engaging the connection tool 312 with the connection tool 308 of the bag body 302. In this case, the buffer 10 of the bag according to the present embodiment has the connecting part 40 detachably attached to one connecting tool 308 of the bag body 302, and the attaching part 86 is a connecting tool on one end side of the shoulder belt 310. Removably attached to 312.

FIG. 25 is a view showing still another example of the use state of the shock absorber shown in FIGS. 20 (A), 20 (B) and FIG. 21, and FIG. 25 (A) shows the shock absorber in various shoulders, for example. It is a perspective view which shows an example of the state attached to the bag, and FIG.25 (B) is a perspective view of a buffer.
The shoulder bag 400 includes a bag body 402. On both side surfaces in the length direction of the bag body 402, stoppers 404 such as an annular stopper cloth are disposed. Further, a shoulder belt 406 can be detachably attached to the bag body 402. The shoulder belt 406 has a connector 408 such as a lever lever attached to both ends thereof. The shoulder belt 406 is attached to the bag body 402 by engaging the connecting tool 408 with the stopper 404 of the bag body 402. In this case, the bag shock absorber 10 according to the present embodiment has the connecting portion 40 attached to one stopper 404 of the bag body 402 and the attaching portion 86 attached to and detached from the connecting device 408 on one end side of the shoulder belt 406. Can be attached freely.

In the bag shock absorber 10 according to the present embodiment, for example, when used in the business bag 200 shown in FIG. 19, the Boston bag 300 shown in FIG. 24, and the shoulder bag 400 shown in FIG. It has common actions and effects.
That is, in the bag (200, 300, 400) to which the bag cushioning device 10 is applied, the bag body (202, 302,) is provided via the handle (204, 304) and / or the shoulder belt (210, 310, 406). 402) When the bag load is applied to the guide rod (24, 84A, 84B) via the mounting portion (26, 86) of the shock absorber 10 and the case 12 via the connecting portion 40 when carrying the As seen in the axial direction of the case 12, the case 12 and the guide rods (24, 84A, 84B) relatively move away from each other.

Thereby, the ring member (34, 92A, 92B) of the pressing portion (32, 90A, 90B) and the support member (20, 78A, 78B) move so as to approach each other, and the compression coil spring (30, 88A) , 88B) is compressed between the support member (20, 78A, 78B) side and the pressing portion (32, 90A, 90B) to generate a spring reaction force of the compression coil spring (30, 88A, 88B). At this time, the burden on the user's wrist, arm, elbow, shoulder, back, waist, knee, etc. due to the dynamic load of the bag (200, 300, 400) is due to compression of the compression coil spring (30, 88A, 88B). It is absorbed by the spring reaction force and relaxed or reduced.

Since the bag (200, 300, 400) operates against the spring reaction force accompanying the compression of the compression coil spring (30, 88A, 88B), the carrying operation is finished and the bag (200, 300, 400) is finished. When the load applied to the handle (204, 304) and / or the shoulder belt (210, 310, 406) is removed, the case 12 and the guide rod (24, 84A, 84B) move relative to each other. Return to the initial state. That is, the bag (200, 300, 400) returns to a stationary state before carrying the bag (200, 300, 400) via the handle (204, 304) and / or the shoulder belt (210, 310, 406). .

The guide rods (24, 84A, 84B) are guided along the inner peripheral surface of the support member (20, 78A, 78B) and smoothly and stably displace in the axial direction of the case 12. 84A and 84B) are less likely to cause lateral vibration and vibration. Further, since the compression coil springs (30, 88A, 88B) are compressed along the outer peripheral surface of the support member (20, 78A, 78B), the lateral deflection of the compression coil springs (30, 88A, 88B) with respect to the coil center line is performed. As a result, the compression coil spring (30, 88A, 88B) is prevented from coming into contact with and rubbing against the guide rod (24, 84A, 84B), and the compression coil spring (30, 88A) , 88B) can be prevented from buckling when compressed, and the compression coil springs (30, 88A, 88B) are protected.

In other words, the support member (20, 78A, 78B) regulates the lateral vibration and vibration of the guide rod (24, 84A, 84B) and the compression coil spring (30, 88A, 88B), and the guide rod (24, 84A). , 84B) and the compression coil springs (30, 88A, 88B). Further, since the friction resistance between the compression coil springs (30, 88A, 88B) and the guide rods (24, 84A, 84B) due to compression of the compression coil springs (30, 88A, 88B) is reduced, the compression coil springs (30 , 88A, 88B) are smoothly compressed.

On the other hand, the coupling portion 40 of the shock absorber 10 is assembled on the other side in the axial direction of the case 12 so as to be supported by the occlusal portions (42, 96). It has become difficult. Therefore, when carrying the bag (200, 300, 400) via the handle (204, 304) and / or the shoulder belt (210, 310, 406), the guide rod (24, 84A, 84B) of the shock absorber 10 is carried out. Even when the load of the bag (200, 300, 400) acts on the connecting portion 40, the connecting portion 40 is unlikely to be detached from the bag body (202, 302, 402) and / or the shoulder belt (210, 310, 406). It has become a thing.

Further, in the bag shock absorber 10 applied to the Boston bag 300 shown in FIG. 24 and the shoulder bag 400 shown in FIG. 25, the guide rods 84A and 84B, the compression coil springs 88A and 88B, and the pressing portions 90A and 90B are particularly provided. Since each member is accommodated in one case 12 in a state of being arranged side by side, a so-called twin type compact structure can be obtained. In this case, even if the buffer function obtained by a single compression coil spring having a predetermined length is replaced with a pair of two coil springs having a length half that of the single compression coil spring. Thus, the originally set buffer function can be maintained.

On the other hand, for example, in a large and relatively heavy bag such as the golf bag 100 shown in FIGS. 7 to 10, the length of the case 12 is increased by adopting the compression coil spring 30 having a long effective length. However, for example, in a business bag 200 shown in FIG. 19, a Boston bag 300 shown in FIG. 24, a shoulder bag 400 shown in FIG. In order to obtain a buffer function more than necessary, an increase in the length of the case causes a problem and is not excellent in terms of aesthetics. Therefore, the shock absorber 10 of the bag shown in FIGS. 20 to 23, for example, having a compact configuration of a twin type, is a handbag type, a shoulder type, a backpack type, and a small and medium type bag that combines two or more of them. The present invention is suitable for application to a handle and / or a shoulder belt.

In addition, the bag cushion 10 according to the present embodiment includes the case 12 and the guide rod (24, 24) in any of the above-described bags (the golf bag 100, the business bag 200, the Boston bag 300, and the shoulder bag 400). 84A, 84B) move (displace) relative to each other in the direction away from each other, the support member (20, 78A, 78B) has its projecting edge (22, 80A, 80B) in the locking recess 62 of the case 12. Locked. That is, the support member (20, 78A, 78B) is restricted from moving in conjunction with the relative movement of the case 12 and the guide rods (24, 84A, 84B), and is stably positioned in the case 12. It has become a thing.

Further, the compression coil spring (30, 88A, 88B) has one end in the length direction in contact with the surface of the ring member (34, 92A, 92B), and the other end in the length direction is the compression coil. When viewed in the length direction of the coil center line of the spring (30, 88A, 88B), the spring (30, 88A, 88B) is brought into contact with the surface (boundary surface) of the boundary portion 64 between the storage portion (52, 74, 76) and the fitting recess 60.
That is, since both sides of the length direction of the compression coil spring (30, 88A, 88B) can be stably supported by the surface, the compression coil spring (30, 88A, 88B) can be stably guided by the guide rod ( 24, 84A, 84B) can be accurately positioned and spaced apart.

The guide rod (24, 84A, 84B) has an attachment portion (26, 86) exposed from one end side in the axial direction of the case 12 at one end portion in the axial direction of the guide rod (24, 84A, 84B). The bag body (202, 302, 402) and the shoulder belt (210, 310, 406) and / or the handle (204, 304). The attachment portions (26, 86) can be attached directly or indirectly. Furthermore, since the connection part 40 is provided with the connection part 40 exposed outside the case 12 on the other side in the axial direction of the case 12, the bag body (202, 302) of the bag (200, 300, 400). , 402) and the shoulder belt (210, 310, 406) and / or handle (204, 304) can be attached directly or indirectly.

In addition, the other end side in the axial direction of the case 12 is strong due to the frictional resistance caused by the close contact of the plurality of occlusal concave and convex portions (48, 97A, 97B) that are engaged with each other in the occlusion row (44, 46, 96A, 96B). It has a structure. Further, the connecting portion 40 is engaged by the engaging portions (50, 95A, 95B), and the outer occlusion row is one of the occlusion rows (44, 46, 96A, 96B) having a firm occlusal structure. Since it is supported by (44, 96A), the case 12 is more firmly and stably held.
Therefore, even if a large load acts on the buffer 10 of the bag, the connecting portion 40 can be inadvertently detached from the case 12, thereby preventing the case 12 from being damaged.

Furthermore, when the shock absorber 10 of the bag according to the present embodiment is manufactured, the guide rod (24, 84A, 84B), the support member (20, 78A, 78B), the compression coil spring (30 , 88A, 88B), the ring member (34, 92A, 92B) of the pressing portion (32, 90A, 90B), the fastening member (36, 94A, 94B), and the connecting portion 40 are easily assembled in the case 12. If the two halves (12A, 12B) are butted together and joined by a method such as ultrasonic welding, the two halves (12A, 12B) can be firmly integrated in a sealed state. . Therefore, the reliability of each member assembled to the case 12 can be improved.

1 to 6, the support member 20 and the projecting edge portion 22 are respectively provided with the fitting recess 60 of the housing portions 52A and 52B of the half bodies 12A and 12B of the case 12, and The support member 20 and the projecting edge portion 22 are arranged on the half of the support member 20 and the projecting edge portion 22, in this case, the axial center line of the support member 20. The two halves having substantially the same shape obtained by dividing the support member 20 and the projecting edge portion 22 are integrally formed in the housing portions 52A and 52B of the case halves 12A and 12B. May be.
Similarly, in the bag cushion 10 shown in FIGS. 20 to 23, the support members 78A and 78B are arranged along the axial center line of the support members 78A and 78B. , 80B may be divided into two halves having substantially the same shape in the half housing parts 74A, 74B, 76A, 76B.

1 to 6 has a configuration in which the ring member 34 of the pressing portion 32 is detachably attached to the other end side in the axial direction of the guide rod 24 together with the fastening member 36. However, for example, the ring member 34 may be integrally formed at one end of the guide rod 24 in the axial direction, and the fastening member 36 may be unnecessary.
