Description

  The present invention relates to a repeater used for continuously relaying a plurality of releases from an operation side to an operation side.

  Conventionally, a release has been used as means for actuating an operating part by a pressing operation at a distant place, such as a camera shutter, a mechanical clutch of an automobile, and an accelerator wire.

  Such a release has a simple structure in which the release wire is exposed to the release outer cylinder whose both ends are open, and its proximal end and distal end are exposed. have.

  However, as described above, the release is a release outer tube in which both ends are opened and the release wire is fitted with its base end and tip exposed, and the frictional resistance increases as the distance increases. In some cases, the operation cannot be sufficiently secured.

  Therefore, recently, for example, an electric release including an electromagnetic actuating part that is surely operated regardless of a remote distance has been used.

  However, for example, as disclosed in Japanese Patent Application Laid-Open No. 2000-104843, a shutoff valve that closes the storage tanks and the pipes of those pipes in the event of an earthquake that considers the stoppage of power supply in the event of an earthquake. The seismic automatic shut-off valve device, which consists of a simple seismic mechanism, a release mechanism that transmits the sensing operation, and a mechanical pipe shut-off valve mechanism that operates in response to the operation of the release mechanism, In the mechanism in which the supply is stopped, it is necessary to transmit the sensing operation by the release mechanism even if the seismic mechanism and the pipe shutoff valve mechanism are separated.

A connecting member 54 having a holding portion 53 for the connecting shaft 61 and movable in the axial direction is arranged so as to be slidable in the axial direction.

  The connecting member 6 holds the elastic body 63 in a compressed state in the non-operating state shown in FIG. 3A, and releases the compressed state of the elastic body 63 when the release 2 on the operation side is operated. Further, a force-intensifying means 64 is provided for applying a biasing force of the elastic body 63 to the release wire 33 in the release 3 on the operating side.

  More specifically, as shown in FIG. 3, the force-intensifying means 64 is installed in a cylindrical exterior body 62 so as to be slidable in the axial direction, and on the outer peripheral wall 65 in a direction crossing the axial line. The inner cylinder 67 is formed with at least a pair of insertion holes 66 and 66 formed at predetermined positions so as to oppose each other, and a coil spring that urges the inner cylinder 67 toward the release wire 33 on the operating side. The elastic body 63, a pair of balls 68, 68 having a diameter that can be inserted into insertion holes 66, 66 formed in the inner cylinder 67, and the operation side release 2 direction installed on the outer peripheral surface of the connecting shaft 61. The first support portions 79, 79 of the balls 68, 68, each of which has an inclined surface that contracts and closes, and the first support portions 79, 79 formed on the inner peripheral surface of the outer peripheral wall 65 are at a predetermined height position. In the insertion holes 66, 66, Slots 70, 70 having substantially right-angled peripheral walls that pass therethrough, and a slot in which a part of each ball 68, 68 disposed in the insertion hole 66, 66 is normally in the non-operating state is formed in the exterior body 62. 70 and 70 and the second support portions 69 and 69 formed of stepped grooves formed on the outer peripheral surface of the operating-side release wire 33 on the connection shaft 61, in succession to the first support portions 79 and 79 of the connecting shaft 61. In combination, the elastic body 63 is held in a contracted state, and when the operation-side release 2 is operated and the connection shaft 61 is pushed toward the release 3 side on the operation side, the connection shaft 61 is released on the operation side. The balls 68, 68 are pushed in three directions to move from the second support portions 69, 69 of the connecting shaft 61 to the first support portions 79, 79, and the balls 68, 68 and the inner peripheral surface of the exterior body 62 The ball deviates instantaneously from the grooves 70, 70 formed in 8, 68, the inner cylinder 67, and the connecting shaft 61 are integrally actuated instantaneously by the elastic body 63 and the release wire 33 of the release 3 on the actuating side is surely pressed by the amplified force to actuate the operating mechanism S. Can be activated.

  In this embodiment, the release repeater 1 used for connecting one release 2 on the operation side and the release 3 on the operation side is shown. However, the release repeater 1 according to the present invention is shown. Can be used by connecting the other end (not shown) of the release wire 33 on the operating side release 3 to the operating side as the release wire 23 on the operating side. Therefore, it goes without saying that a large number of releases can be used at any distance by sequentially connecting them via the release repeater of the present invention, and the final operating force can be increased even at a short distance. In particular, since it does not require any electric power, it can be used not only at the time of a power outage, but also extremely safe and economical.
