Description

  The present invention relates to a cable support, particularly a cable support suitable for supporting a cable attached to a medical or nursing-use electric bed or a treatment chair, or a cable attached to various devices used in the vicinity thereof. Is.

  For example, medical and nursing electric beds are equipped with a remote controller for operating the raising and lowering and raising and lowering of the floor, and a cable such as a curl cord is provided between these and the control device on the main body side of the electric bed. Is connected. When the remote controller is not in use, the hook member provided on the remote controller is hooked on the side pipe of the side rail and held.

  At this time, the cable may hang down to the floor on which the electric bed is placed. In this case, there is a risk that the cable is contaminated or a person is caught on the hanging cable and an accident occurs. For this reason, a means for supporting the cable so as not to hang down to the floor is required.

As means for supporting a cable, for example, Patent Document 1 describes a wiring cable holder that is used by being attached to a chassis or the like of a device that requires cable wiring. This wiring cable holder is provided with a curved cable holding plate on the upper side of the plate-like cable support, and the hook provided on the tip side is engaged with the cable support to hold the cable at the curved portion. The cable support itself is detachably attached to the chassis or the like of the device by engaging the hook with the engagement hole.
Japanese Patent No. 2543117

  For example, in the electric bed described above, the position where the remote controller is held when not in use is not necessarily limited to the side pipe of the side rail, so it is actually necessary to attach the cable support to a predetermined position such as the bed. Not right. And since the shape of the site | part etc. in those attachment positions also changes, the attachment form becomes various.

  For this reason, it is difficult to apply what is described in Patent Document 1 described above to the bed described above.

  On the other hand, since the conventional cable supports including those described in Patent Document 1 require manual operation when removing the cable from the cable support, they can be removed even if a strong force is applied from the cable side. In this case, inconveniences such as disconnection of the cable due to an excessive load occur.

  The present invention has been devised in view of the above points. That is, the cable support of the present invention has a first object to enable attachment in various attachment forms depending on the attachment position. In addition, the second object is to prevent the occurrence of cable disconnection even when an excessive load is applied from the supporting cable side.

  In order to solve the above-described problem, in the present invention, first and second engaging portions are formed on one end side and the other end side of a belt-like elastic body curved in an arc shape, respectively. The belt support elastic body can be held in an annular shape by engaging the joint, and a cable insertion support portion is formed on one end side of the belt plate elastic body. Suggest ingredients.

  In the present invention, it is proposed that, in the above-described configuration, an introduction protrusion is formed on the opening side of the insertion support portion.

  In the present invention, in the above configuration, it is proposed that the insertion support portion is formed below the first engagement portion or formed facing away from the first engagement portion.

  In the present invention, in the above configuration, the band plate-like elastic body is formed by gradually reducing the plate thickness on the other end side where the second engagement portion is formed, and the rigidity of the portion reaching the other end side, We propose to make it smaller than one end.

  According to the present invention, in the above configuration, the first engaging portion is configured as a protruding piece portion folded back in a hook shape, and the second engaging portion is a hook-shaped curve that engages with the tip of the protruding piece portion. Proposed to be configured as a single part.

  In the present invention, it is proposed to round the tips of the first and second engaging portions in the above configuration.

  In the above configuration, in the cable support of the present invention, when the first and second engaging portions are not engaged, the belt-like elastic body curved in an arc shape can be used as a hook. When the part is plate-shaped or planar, it can be hooked on it and pinched by elasticity to be securely fixed.

  On the other hand, in the cable support tool of the present invention, when the first and second engaging portions are engaged, the band plate-like elastic body can be held in an annular shape. It can be securely fixed by being fitted into the part and held in an annular shape.

  As described above, the cable support of the present invention can be supported so as not to hang down by being fixed at various positions of attachment positions and inserting the cable into the insertion support portion.

  At this time, if an introduction projecting piece is formed on the opening side of the insertion support portion, the opening side is formed narrowly, so that the cable can be easily inserted into the insertion support portion which is relatively difficult to insert. Moreover, since the opening side is narrowly formed, it is possible to prevent the inserted cable from coming off due to vibration or the like.

  Here, when the cable support of the present invention is used as a hook and fixed at the mounting position, when a large external force is applied from the cable in the direction of pulling the cable support, the cable support The other end of the elastic member is elastically deformed, and is removed without being damaged from the plate-shaped portion at the mounting position by a larger force. Therefore, disconnection of the cable due to an excessive load can be prevented.

  In addition, when the band plate-like elastic body is held in an annular shape by the engagement of the first and second engaging portions and the cable support is fixed to the tubular portion at the attachment position, the cable support is When a large external force in the pulling direction is applied from the cable, the cable support member is elastically deformed at the other end side of the band plate-like elastic body, so that the engagement between the first and second engaging portions is released, and the band is further removed. The other end side of the plate-like elastic body is elastically deformed, and depending on the magnitude of the force, the plate-like elastic body comes off without being damaged from the tube-shaped portion at the attachment position. Therefore, disconnection of the cable due to an excessive load can be prevented.

  The band-plate-like elastic body is formed by gradually reducing the plate thickness on the other end side where the second engagement portion is formed, and by forming the rigidity of the portion reaching the other end side smaller than the one end side, The above-described elastic deformation on the other end side can be favorably performed.

  Further, when the first engaging portion is configured as a protruding piece portion folded back in a hook shape, and the second engaging portion is configured as a hook-shaped curved piece portion that engages with the tip of the protruding piece portion, The engagement between the first and second engagement portions can be surely released, and the tips of the first and second engagement portions are rounded to further ensure the engagement. Can do.

  The cable support A having the above-described configuration can be manufactured by integral molding using hard plastics as the band plate-like elastic body 1, but all or part of the metal is applied as the band plate-like elastic body 1. You can also

  In the above configuration, in the cable support A of the present invention, when the first and second engaging portions 2 and 3 are not engaged, the strip-shaped elastic body 1 curved in an arc shape can be used as a hook. Therefore, for example, as shown in FIG. 5, when the attachment portion 8 b is plate-shaped, it can be hooked on and clamped by the elasticity of the band plate-like elastic body 1 to be securely fixed.

  FIG. 9 shows an example of a state in which the cable support A of the present invention is fixed using the band plate-like elastic body 1 as a hook. In FIG. 9, reference numeral 9 denotes a side frame of an electric bed (not shown). On the upper side of the side frame 9, a side rail 10 as shown in the drawing and a fitting for attaching other options are attached. The portions 11 are formed at a predetermined interval. The side rail 10 is supported in a standing state on the side portion of the electric bed by fitting the mounting rod 12 provided on the lower side thereof to the fitting portion 11. The side rail 10 holds a left-side member 13 in the figure so as to be able to turn, and the left-side member 13 is configured to be used as an assistance bar.

  Reference numeral 14 denotes a remote controller for operating raising / lowering and raising / lowering of the floor portion of the electric bed, and a cable 4 such as a curl cord is connected between the control devices (not shown) on the main body side of the electric bed. The remote controller 14 supports the hook-shaped support 15 provided on the upper side by hooking it on the upper crosspiece member 16 of the side rail 10. Reference numeral 17 is a plate-like member configured on the lower side of the side rail 10, and 18 is a vertical pipe provided between the left side portion of the plate-like member 17 in the drawing and the upper horizontal rail member 16, and is close to the vertical pipe 18.

The other end b of the elastic body 1 is fitted into the fitting portion 11 formed on the side frame 9 described above, and the one end a is positioned outside the side frame 9 and fixed. In this case, the plate-like or planar portion 8 b is a portion of the side frame 9.

  In this state, the cable support A is securely fixed by being clamped by the elasticity of the band plate-like elastic body 1 while the other end side of the band plate-like elastic body 1 is fitted into the fitting portion 11. In this state, by inserting the cable 4 into the insertion support portion 5, it can be supported so as not to hang down.

  In the support state shown in FIGS. 9 and 10, when a large external force is applied to the cable support A from the cable 4 in the direction in which the one end a is pulled downward or laterally in the figure, the belt-like elastic body 1 The other end b of the cable is elastically deformed, and the cable support A is detached from the portion 8b without being damaged by a larger force. Therefore, disconnection of the cable 4 due to an excessive load can be prevented.

  In this embodiment, the belt-like elastic body 1 is formed by gradually reducing the plate thickness at the other end b where the second engaging portion 3 is formed, and the rigidity of the portion reaching the other end is reduced to one end. Since it is formed smaller than the side a, the elastic deformation of the other end b is favorably performed as compared with the case of the equal thickness.

  Next, in the cable support A of the present invention, when the first and second engaging portions 2 and 3 are engaged, the belt-like elastic body 1 can be held annularly as shown in FIG. In the case where the portion 8a at the mounting position in the tube is tubular, it can be securely fixed by being fitted into the portion 8a and held in an annular shape. And it can support so that it may not hang down by inserting the cable 4 in the insertion support part 5 of the cable support A of a fixed state.

When a large external force is applied from the cable 4 that pulls the one end side 8a of the cable support A downward or laterally in the figure while the cable support A is fixed, the cable support A is connected to the other end b of the strip elastic body 1. As a result of elastic deformation, the first and second engaging portions 2 and 3 are disengaged sequentially after the states shown in FIGS. Further, the other end b of the band plate-like elastic body 1 is elastically deformed and comes off without being damaged from the tube-shaped portion 8a at the attachment position depending on the magnitude of the force. Therefore, disconnection of the cable 4 due to an excessive load can be prevented.

  In this embodiment, the first engaging portion 2 is configured as a protruding piece portion folded back in a hook shape, and the second engaging portion 3 is a hook-shaped curved piece portion that engages with the tip of the protruding piece portion. Therefore, as can be seen from the progress of FIGS. 5 to 8, the engagement between the first and second engaging portions 2 and 3 is reliably released. In this embodiment, since the tips of the first and second engaging portions 2 and 3 are further rounded, the above-mentioned engagement is more reliably performed.
