It is possible to detect the strength of the copper when it is tied, that is, the traction strength, or the degree of relaxation of the thin copper from the traction state, and to compensate for the predetermined relaxation length within the extension range of the compression type elastic body. The present invention relates to a traction strength sensing and damping device which can also be used as a damping device for towing or suspension devices.

して所望強度に薄銅の牽引緊縛力を得、更に常時その強
度に維持するための技術的手段が存在していなかった。Conventionally, for example, in a type of truck that loads cargo on an open platform, in order to prevent the loaded cargo from collapsing, a thin piece of copper with one side fixed to the edge of the platform is successively hung over the loaded cargo. He handed her over and tied her up on the loading platform. In addition, when loading cargo, there are conventional methods and rules regarding the thin copper hooking method to prevent the bonded state from unraveling or loosening due to vibrations while the truck is running. However, in terms of -JW, it often depends on the skill and sensitivity of the worker, and it is necessary to obtain the desired strength of the traction and binding force of the thin copper according to the loaded cargo or its loading amount and type, and to maintain that strength at all times. There were no technical means to do so.
また、重量物の牽引又は懸吊装置、例えばケーブルカー

車の走行中に薄銅が弛緩すると急激にその牽引緊縛力が
失われて荷崩れを起こしたり、また牽引緊縛力が強すぎ
ると積載貨物やその梱包を傷めたりする問題があった。Therefore, depending on the type and amount of cargo loaded on the loading platform, sufficient traction and binding force of the thin copper may not be obtained, and in addition, if the thin copper loosens while the truck is running, the traction and binding force may be rapidly lost. There was a problem that the load could collapse, and if the traction force was too strong, the loaded cargo or its packaging could be damaged.
また、張引型のコイルバネは、圧縮型のコイルバネに比

For example, by interposing the thin copper in the tension direction in the middle of the thin copper that is being passed over the cargo loaded on a freight vehicle, a predetermined traction strength, that is, a binding force is generated in the thin copper, and the traction is constantly maintained. In order to maintain the binding force, it is possible to detect the degree of loosening and compensate for the predetermined length of loosening within the range of extension of the elastic body, and it can also be implemented as a shock absorber for towing or suspending heavy objects if desired. The purpose of this research is to propose a traction strength detection and shock absorbing device.

Accordingly, the desired traction force can be obtained by pulling the load up to the traction strength empirically required, and the reduction in the traction force can be detected by the loosening of the thin copper to which the loaded cargo is tied. , the elastic body in the compressed state has the effect of absorbing and compensating for the relaxation length of the thin copper within the range of the amount of elongation that can be restored, that is, the movement length.

4 are formed separately and fixed by welding or other appropriate means at the respective boundary parts (the part indicated by the arrow E and the part indicated by the F arrow) in order to form an annular body using the axioms 32 and 34 of both parts. According to the embodiment, there is an advantage that the connecting ring 1.2 can be constructed relatively easily without requiring complicated bending work or mounting work of pins 21, etc. to each component.

ことはない。The elastic body 3, that is, a compression type coil spring, etc., has superior breaking strength as described above compared to a tension type coil spring, etc., and if an overload exceeding a predetermined traction strength is applied to the linked rings 1 and 2. However, it is not easily destroyed, and even if it is destroyed, there is little risk that the ring itself will break and separate, and the loaded cargo and heavy objects can be tied down and fixed.
Also, the load w4R being towed or suspended will not be cut off and separated from the mounting portion of the traction strength detection and shock absorbing device according to the present invention.

形状の筒体として形成したものである（第２図参照）。Reference numeral 4 denotes a guide cylinder that covers the outer periphery of the linked rings 1.2 having the above structure, and corresponds to the substantially cross-shaped cross-sectional shape formed by the two linked rings 1.2, and has an annular shape that intersects and protrudes from the cross-shaped cross section. It is formed as a cylindrical body having an approximately cross-shaped cross section to accommodate the partial rings 12 and 14 of the body (see FIG. 2).

。Further, the guide tube 4 is integrally fixed to one of the linked rings 1.2 by a suitable method such as spot welding, and the end of the other linked ring 1 or 2, that is, the hooking ring 13 side is connected to the elastic body 3. It is configured to move in and out of the guide tube 4 against the urging force of.

照）。In the above configuration, it is possible to form a scale 5 as a detection means on the end face of the guide cylinder 4 or the end face of the linking ring 1.2, if desired, and the scale 5 allows the linking rings 1, 2 to be mutually applied with a predetermined traction force. It is possible to read the amount of movement when the elastic body 3 is compressed and pulled in the opposite longitudinal direction, that is, the traction strength or the degree of relaxation from the traction state. As shown in FIG. 7, this scale 5 is formed by opening a window 6 on the end face of the guide cylinder 4, and covering the window 6 with a transparent plate 7 or the like on which a predetermined scale 5 is engraved or drawn. It is configured so that the amount of movement of the linked ring 1.2 can be recognized visually through the transparent plate 7, etc., or a similar structure is provided on the end face along the moving direction of the part where the linked ring 1.2 is exposed from the guide tube 4. The scale 5 can also be formed by being engraved or pasted (see FIG. 1).

に成る。As shown in Fig. 8, the amount of movement between the above-mentioned linked rings 1 and 2 is based on the end of the linked rings 1 or 2 on one side (line G line), and the distance between the linked rings 1 and 2 on the other side can be pulled. Determined by quantity. This amount of traction is determined by the elastic body 3 that hangs between the long diameter between the inner edges of each linked ring 1.2 and the inner edge of both linked rings 1.2.
It is determined relatively by the amount of expansion and contraction. That is, if the amount of expansion and contraction of the elastic body 3 is large, the major axis can be formed to be large, and conversely, when the major axis is small, the amount of expansion and contraction of the elastic body 3 must be small. However, in any case, it is preferable that the elastic body 3 is interposed such that it substantially coincides with the relative major axis range of the two connecting rings 1.2 in an unloaded state, or that it leaves some residual pressure. Therefore, during the period from the state in which the elastic body 3 is completely compressed (but line portion) to the state in which it is completely expanded,
A biasing force of the elastic body, that is, an elastic repulsion force is generated on the double ring.
