[Detailed description of the device]

[0001]

[Industrial applications]

 TECHNICAL FIELD The present invention relates to a shock absorber, and more particularly to a shock absorber that can be attached to a vehicle such as an automobile or a ship and can absorb the impact force in the event of a collision.

[0002]

[Prior art]

 Generally, a bumper is attached to an automobile in order to soften the impact force in a collision. For example, Japanese Utility Model Laid-Open No. 48-11533 includes a rubber diaphragm mounted in a bumper body and a support cylinder having one end connected to the diaphragm so that the other end can be inserted and the other end connected to a vehicle body. An air spring bumper in which compressed air is enclosed in a diaphragm and a support cylinder is disclosed. In this air spring type bumper, the diaphragm pushed into the support cylinder at the time of collision absorbs the impact force by compressed air.

In addition to bumpers, recently, some automobiles are equipped with an air bag that expands in the driver's seat and its auxiliary seat due to the impact at the time of a collision and protects the human body from the impact force.

[0004]

[Problems to be solved by the device]

 However, the conventional bumper described above has drawbacks in that it is troublesome to mount the bumper and it is difficult to keep the compressed air in the diaphragm and the support cylinder in a sealed manner.

In addition, although the air bag has been recently developed and may be installed in a new car, it is not installed in a used car and cannot be installed easily. Is.

Therefore, the present invention has been made to solve the above-mentioned drawbacks, and an object thereof is to provide a shock absorber that can be easily attached to a desired place of a vehicle such as an automobile and can reduce an impact force. To provide.

[0007]

[Means for Solving the Problems]

 The present invention has been made in view of the above object, and its gist is to include a cushioning member and a supporting member that supports the shock absorbing member, and the supporting member is made of a material that is destroyed by an impact. It is a characteristic shock absorber.

Here, as the cushioning member, a spring, a large number of spring washers, and the like are conceivable.

[0009]

[Action]

 The shock absorber of the present invention is a shock absorber, for example, a support member made of a material that is destroyed by an impact, in which a large number of spring washers are continuously connected, and a container made of plastic, for example, a tip of a bumper of a vehicle. When mounted on the side edge of a car or a car, the container is destroyed in the event of a collision, and a large number of spring washers installed absorb the impact force.

[0010]

【Example】

 An embodiment of the shock absorber according to the present invention will be described below with reference to the accompanying drawings. The shock absorber of the present invention can be applied to various vehicles such as ships and automobiles, but any vehicle can be mounted in the same manner. Therefore, in the present embodiment, only the case of the automobile will be described as a representative.

FIG. 1 is a schematic perspective view showing a part of an automobile equipped with a shock absorber according to the present invention. As shown in this figure, three bumpers 10 are attached to the tip of the bumper 2 of the automobile 1, and two shock absorbers 10 are attached to the left and right ends of the vehicle body 3 (only one left end is shown in the figure). Has been.

FIG. 2 is a schematic perspective view in which only the vicinity of the left shock absorber 10 among the three shock absorbers 10 shown in FIG. 1 is enlarged, and the shock absorber 10 is disassembled and shown. As shown in this figure, the shock absorber 10 is composed of six spring washers 4 as shock absorbing members, which are connected in series, and a container 5 for accommodating the spring washers 4 in the connected state.

The spring washer 4 is made of lightweight metal such as aluminum.

The container 5 is composed of a cylindrical main body 5a for accommodating six spring washers 4 arranged in series, and a lid 5b of the main body 5a, both of which are materials that are destroyed by impact, such as plastic and cardboard. Consists of. In order to attach the shock absorber 10 to the bumper 2, the bumper 2 is provided with an opening 2a, and the container 5 is fitted and attached thereto.

FIG. 3 is a diagram schematically showing a state of the spring washer 4 housed in the container 5 of the shock absorber 10. As shown in this figure, the spring washer 4 is housed in the container 5 in a lightly pressed state, and the lid 5b is welded to the main body 5a.

FIG. 4 is a schematic view showing a mounting state of the shock absorber 11 shown in FIG. The same components as the shock absorber 10 are designated by the same reference numerals, and the description thereof will be omitted. Only different components will be described. As shown in this figure, the shock absorber 11 comprises a spring washer 4, a bolt 6 inserted into the spring washer 4, and a nut 7 of the bolt 6, and the bolt 6 and the nut 7 are the same as the container 5 described above. Is made of a material that is destroyed by impact, such as plastic or cardboard. To mount the shock absorber 11 on the side end of the vehicle body 3, a screw hole 3a is provided at the mounting position, and the tip of the bolt 6 is screwed into the screw hole 3a.

Next, the shock absorbing operation of the shock absorbers 10 and 11 will be described.

When the automobile collides with the shock absorbers 10 and 11, and the heads of the lid 5b and the bolt 6 are impacted in the vehicle body direction, the container 5 and the bolt 6 are destroyed, and the spring washer 4 presses the vehicle in the vehicle body direction. However, the spring force of the spring washer 4 in the direction of the vehicle body absorbs this pressing force and reduces the impact.

Here, the shock absorber of the present invention can be attached to the vehicle by using, for example, an adhesive, a double-sided tape, or the like, and is not limited to the embodiment as long as the shock absorber is attached so as not to come off easily. Further, the supporting member of the spring washer is not limited to this embodiment as long as it can be supported in a continuous state. Further, as the material of the spring washer, iron or the like can be used, but lightweight metal such as aluminum is desirable so that it can be easily attached to a vehicle. Further, the mounting position of the shock absorber and the number thereof are not limited to those in this embodiment.

[0020]

[Effect of device]

 As described above, according to the shock absorber of the present invention, since it is provided with the shock absorbing member, for example, a large number of consecutively provided spring washers, the shock force can be softened, and therefore, when the shock absorber is attached to a vehicle, for example, an automobile. , The impact at the time of a collision can be softened and the influence on the human body of the passenger can be reduced.

Further, since the shock absorber of the present invention has a simple structure, it can be easily attached to a desired position in a desired number regardless of whether it is a new car or a used car.
