Description

  The present invention relates to an adapter for use in a remote control yacht that grips an object to be gripped such as a part in overhead wire work or the like.

  As shown in FIGS. 9 (A) and 9 (B), the conventional remote control YATCO has an insulating main rod 101 with an insulating umbrella 105 fitted and fixed at an intermediate portion, one end of the main rod 101 and the vicinity thereof. A pair of gripping parts 102a and 102b provided facing the tip of the movable part 106 attached to the head, an operating part 103 attached in the vicinity of the other end of the main shaft 101, the movable part 106 and the operating part 103, An electrically insulating connecting rod 104 is provided as means for transmitting a force generated by operating the operation unit 103 to the movable unit 106.

  The gripping portions 102a and 102b are provided with unevenness for preventing slipping on the contact surfaces facing each other, and can grip various objects to be gripped in overhead wire construction or the like. On the other hand, in the case of using a yatco, a remote operation yatco having a gripping part corresponding to the shape and type of the object to be gripped must be prepared separately.

  Therefore, in the following Patent Document 1, a plurality of adapters capable of performing various operations on the object to be grasped can be attached to and detached from a single remote control unit without preparing a plurality of types of remote control units. There has been proposed an adapter that can perform various operations and realizes cost reduction and a reduction in the number of parts. This adapter can be detachably attached to a gripping part of a Yatco, and includes a tool for performing at least one of clamping, cutting, cutting, and measuring operations on an object to be gripped.

For such an application that the object to be grasped is gripped and operated, it is desirable that a slip stopper is provided on the contact surface of the grasping part with the object to be grasped. Conventionally, a protrusion parallel to the contact surface of the gripping part has been provided to prevent slipping. Moreover, in order to hold | grip a rod and a cylinder material stably, forming the contact surface of a holding part in a reverse arch-shaped recessed part is also performed so that such to-be-held objects may fit.
JP 2003-170364 A

  However, the anti-slip effect by the parallel ridges is large for the force in the direction orthogonal to the length direction of the ridges, but the anti-slip effect for the force in the parallel direction is low. In addition, when the contact surface of the gripping part is formed in a reverse arch-shaped recess, it is possible to securely grip the bar or cylinder along the recess, but the bar or cylinder extending in the orthogonal direction It cannot be gripped firmly. For this reason, in the latter case, it is necessary to prepare a plurality of Yatcos and adapters each having a grip portion having different ridges and dent directions on the contact surface.

  In view of the above problems, the present invention can work without preparing a plurality of types of yatcos and adapters even when the direction of the force against the object to be grasped and the direction of the bar or cylinder as the object to be grasped are different. An object of the present invention is to provide an adapter for Yatco that can be performed and that realizes cost reduction and a reduction in the number of parts.

  The adapter according to the present invention includes a main rod, a pair of grip portions provided near one end of the main rod for gripping an object to be grasped, an operation portion provided near the other end of the main rod, and the operation portion. An adapter used for a remote control yatco provided with means for transmitting the force applied to the gripping part, and a base part detachably engaged with the gripping part of the yatco, and a base detachably engaged with the base part And a non-slip portion having a contact surface with the object to be grasped, and the engaging surfaces of the base portion and the anti-slip portion are substantially congruent to each other and formed in a rotationally symmetric shape including a regular polygon. And

  The embodiment of the present invention has the following configuration. Each engagement surface of the base and the anti-slip portion is formed of a magnet or a magnetic material. At least the contact surface of the anti-slip portion with the object to be grasped is formed of an elastic material. The contact surface is provided with a plurality of protrusions or a plurality of conical protrusions parallel to each other. It is preferable that these protrusions or protrusions have a deviation so that they do not contact the protrusions or protrusions of the adapter attached to the opposing gripping part of the Yatco. Alternatively, the contact surface preferably has an inverted arch-shaped recess.

  According to the adapter of the present invention, the engaging surfaces of the base portion and the anti-slip portion are substantially congruent with each other and formed in a rotationally symmetrical shape, for example, a square shape. As a result, the anti-slip portion can be removed from the base, rotated by an appropriate angle (for example, 90 degrees), and re-engaged with the base. There is no need to prepare various types of Yatsuko and adapters, and it is possible to reduce costs and the number of parts.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the configuration of the remote control yatco to which the adapter according to the embodiment is attached is the same as that of the above-described conventional example, so the description thereof will be omitted and the adapter used for this will be described in detail.

  As shown in FIG. 1, the adapter 1 includes a base 2 that is detachably engaged with a pair of gripping portions 102 a and 102 b (see FIG. 9) of a remote control yatco, and a slip that is detachably engaged with the base 2. It is comprised with the stop part 3. FIG.

  The base 2 is made of a metal material, and as shown in FIG. 2, the front has an opening 4 into which the gripping portion 102a or 102b of the yatco is inserted, and a concave insertion portion 5 is formed from the opening 4 inside. Yes. On the upper surface of the base portion 2, a slit 7 cut out in the opening 4 from a portion corresponding to a rib 116 (see FIG. 9B) formed on the surface of the gripping portions 102 a and 102 b of the Yatco in the insertion direction of the gripping portion. Is formed.

  At the center of the upper surface of the base portion 2, as shown in FIGS. 1 to 3, an engagement pin 9 that engages with the surface of the grip portion 102 a or 102 b of the remote control yatco, and an engagement pin 9 that communicates with the insertion portion 5. Are provided with a pin receiving portion 11 having a pin hole 10 at the center thereof, and a coil spring 12 for urging the engaging pin 9 toward the insertion portion 5 in the pin hole 10.

  As shown in FIGS. 2 and 3, the engaging pin 9 is formed by a head portion 14 and a shaft portion 15, and a convex portion 16 is projected from a side surface of the shaft portion 15. A concave groove 17 is formed in the pin hole 10 in the sliding direction of the engaging pin 9, and the convex portion 16 moves along the concave groove 17 to guide the sliding of the engaging pin 9. It has a configuration.

  The shaft portion 15 of the engagement pin 9 is always urged by the spring 12 so that the lower end of the shaft portion 15 protrudes into the insertion portion 5, while the urging force is applied to the head portion of the engagement pin 9 as shown in FIG. The lower surface of 14 is restricted by contacting the upper end of the pin receiving portion 11.

  After the engaging pin 9 is pulled up against the force of the spring 12 until the convex portion 16 is exposed to the outside of the pin hole 10, the convex portion 16 overlaps the concave groove 17 with the shaft portion 15 as the center. When the hand is released after being turned so as to come to a position where it does not become, the convex portion 16 comes into contact with the peripheral edge of the opening at the upper end of the pin receiving portion 11. Thereby, the engagement pin 9 can be stopped at the engagement release position.

  The slit 7 has a guide function for receiving and guiding the convex reinforcing rib 116 formed on the outer surface of the gripping portion when the adapter 1 is attached to the gripping portion 102a or 102b of the Yatco.

  An engaging plate 6 is integrally provided on the lower surface of the base 2. Alternatively, it may be fixed by appropriate means such as welding. The engagement plate 6 is formed in a square shape with a magnetic material such as a magnet.

  As described above, the base 2 is formed of a metal, but is formed of an insulator such as a synthetic resin, or coated with an insulating material, thereby preventing an electrical short circuit between the object to be grasped and other objects in the vicinity thereof. It is preferable to make it highly safe, such as preventing.

  Next, an operation of attaching / detaching the adapter base 2 to / from the gripper 102a or 102b of the Yatco will be described.

  First, when the head portion 14 of the engagement pin 9 is grasped and pulled up against the force of the spring 12 described above, the lower end of the shaft portion 15 is retracted from the insertion portion 5, so that the grip portion can be inserted into the insertion portion 5. It becomes a state. At this time, by rotating the engaging pin 9 about the shaft portion 15, the convex portion 16 of the engaging pin 9 is hooked on the peripheral edge of the pin hole 10 opening of the pin receiving portion 11 and the engaging pin 9 is disengaged. Stop in position. Next, after positioning the grip portion 102 a or 102 b so that the rib 116 formed on the surface thereof is aligned with the slit 7, the grip portion is pushed into the insertion portion 5 from the opening 4. Then, when the engaging pin 9 is rotated around the shaft portion 15 again and the head portion 14 is released in a state where the convex portion 16 is fitted in the concave groove 17, the shaft portion 15 is held by the gripping portion by the urging force of the spring 12. 102a or 102b is brought into contact, and the base portion 2 is engaged with the grip portion. In this state, when removing the adapter 1 from the gripping portion, an operation reverse to the above may be performed.

  Next, the anti-slip | skid part 3 consists of the engaging part 20 engaged with the base 2, and the contact part 21 which contacts a to-be-held object. The engaging portion 20 and the contact portion 21 are fixed by appropriate fixing means such as adhesion.

  The engaging portion 20 is formed of a magnetic material such as iron, and has a square recessed portion 22 in which the engaging plate 6 of the base portion 2 fits exactly. When the engagement plate 6 is fitted into the recessed portion 22, the base 2 and the anti-slip portion 3 are adsorbed by the magnetic force acting between the engagement plate 6 and the engagement portion 20. By this action, the base 2 and the anti-slip part 3 can be easily integrated. Moreover, when removing the anti-slip | skid part 3 from the base part 2, what is necessary is just to separate the anti-slip | skid part 3 and the base 2 with force larger than magnetic force, and can attach or detach easily. When the adapter 1 is attached to the remote control yatco and the object to be grasped is clamped, no force is applied in the direction to separate the anti-slip part 3 and the base part 2, so It will not come off.

  Note that the engagement plate 6 and the recessed portion 22 may be congruent and rotationally symmetric, and may be a polygon such as a regular octagon. When the engagement plate 6 and the recessed portion 22 are regular octagons, the base portion 2 can be attached to the anti-slip portion 3 by being rotated 45 degrees. In the illustrated example, the upper surface of the recessed portion 22 is formed of a magnetic material such as iron, and the engagement plate 6 is formed of a magnet. However, the configuration may be reversed, or both may be magnets. .

  A flange 23 having a height equivalent to the thickness of the engaging plate 6 is provided around the recessed portion 22, whereby the recessed portion 22 forms a square having a size that allows the engaging plate 6 to fit tightly. The base portion 2 and the anti-slip portion 3 are coupled together without rotating relatively.

  The contact portion 21 is formed of an elastic body such as rubber. In addition, the contact surface of the contact portion 21 with the object to be grasped has various anti-slip shapes as will be described later, so that contact resistance with the object to be grasped is achieved. To increase. Various shapes of the contact portion 21 are conceivable depending on the shape, type, and material of the object to be grasped. By replacing the non-slip portion 3 having such a different contact portion 21 with respect to the base 2, Anti-slip can be selected according to the type. Hereinafter, an example of the contact portion 21 will be described.

  FIG. 4 shows a non-slip portion 3a of the first example provided with a contact portion 21a having a plurality of protrusions 31 parallel to each other. The protrusions 31 are provided at equal intervals, and effectively prevent the object to be gripped from sliding mainly in a direction orthogonal to the protrusions 31.

  Further, when using a force in the length direction of the ridge 31 with respect to the object to be grasped, the anti-slip portion 3a is removed from the base portion 2, and rotated 90 degrees around the center line L as an axis and attached again. Thus, the direction of the ridge 31 can be changed by 90 degrees. Thereby, the frictional force required for gripping can be obtained without preparing another anti-slip part.

  FIG. 5 shows a non-slip portion 3b of a second example provided with a contact portion 21b having a plurality of conical protrusions 41. Since these protrusions 41 are arranged at equal intervals and do not have a certain directionality like the parallel protrusions 31 described above, it is possible to effectively prevent the object to be gripped from slipping in all directions.

  As shown in FIG. 6, the adapter 1 is attached to a pair of gripping portions 102a and 102b facing each other for remote operation, so usually, a pair of anti-slip portions 3 having the same shape is attached to the base 2 for use. However, as shown in FIG. 7 using the non-slip portion 3a of FIG. 4 as an example, it is also possible to use one having a deviation such that the protrusion of one adapter does not abut against the protrusion of the opposite adapter. . According to the anti-slip portion 3a shown in FIG. 4, the anti-slip portion 3a of the adapter 1 attached to one of the gripping portions 102a and 102b of the Yatco is connected to the center line L with respect to the adapter attached to the other. 7. An adapter having a deviation so that the protrusion of one adapter does not abut against the protrusion of the opposite adapter as shown in FIG. 7 simply by engaging the base 2 with the shaft rotated 180 degrees. It can be.

  Further, by providing the object to be grasped M1 with the concave groove 32 in which the protrusion 31 fits, the object to be grasped M1 can be grasped more reliably.

  FIG. 8 shows an anti-slip portion 3c of a third example provided with a contact portion 21c having a concave portion 51 in which the contact surface has an inverted arch shape and a large number of parallel protrusions are formed. Since both ends of the contact portion 21 c are convex portions 52, friction is increased by increasing the contact area when gripping a rod-like or tubular object M <b> 2 such as a fuse cylinder, electric wire, or bolt parallel to the recess 51. Resistance can be increased. Further, even if a force is applied to the object to be grasped M2 in the direction W perpendicular to the concave portion 51, the object to be grasped M2 hits the convex portion 52, so that it does not shift in the W direction.

  In addition to the parallel protrusions shown in FIG. 8, the aforementioned conical protrusions or the like may be formed on the contact surface of the contact portion 21c. In addition, when gripping a bar or cylinder of the object to be gripped in a direction orthogonal to the length direction of the recess 51, the anti-slip portion 3c is removed from the base 2, rotated 90 degrees, and reattached. Since the direction of 51 can be changed by 90 degrees, it is possible to cope with one anti-slip part without preparing another anti-slip part.

  Although various embodiments have been described above, the present invention is not limited to the configurations of these embodiments, and various forms and modifications are possible. In particular, the contact portion 21 of the anti-slip portion can be formed in an appropriate form depending on the material, shape, etc. of the object to be grasped.
