The elastic protrusion 51 has a protrusion size capable of interfering with the recess 24 of the movable metal fitting 20 , and the tip of the elastic protrusion 51 is formed into a shape capable of fitting into the recess 24 .

The second guide part 60 is a part corresponding to the bottom surface of the housing space for housing the movable fitting 20, and the second guide part 60 has a first guide rail part 61 on the retracted side (X-axis negative side), an extended side (X-side positive side), side) of the second rail portion 62 and a receiving portion 63 serving as a receiving space for inserting the protruding portion 21 of the movable fitting 20 into these rail portions.

In the second guide portion 60 , the first rail portion 61 and the second rail portion 62 are provided with the receiving portion 63 interposed therebetween, that is, the receiving portion 63 is spaced apart. In the present embodiment, the first rail portion 61 and the second rail portion 62 are arranged linearly along the advancing and retreating direction of the movable metal fitting 20 (the extending and contracting direction of the auxiliary arm 10 ) via the receiving portion 63 . In other words, in the present embodiment, the first rail portion 61 and the second rail portion 62 are provided on a straight line at intervals of the receiving portion 63 in the advancing and retreating direction.

The first rail portion 61 and the second rail portion 62 are formed by providing elongated holes in the bottom surface of the accommodation space of the base metal fitting 40 parallel to the telescopic direction. The groove width (length in the Y-axis direction: length in the left-right direction) of the first rail portion 61 and the second rail portion 62 is set larger than the diameter of the neck portion 22 of the protruding portion 21 (see FIG. 5 ), and smaller than the diameter of the head portion. The diameter of the portion 23 is smaller than the left-right width of the section of the movable fitting 20 where the concave portion 24 is arranged.

The front-rear width of the receiving portion 63 (length in the X-axis direction: length in the front-rear direction) is set larger than the diameter of the head portion 23 of the protrusion 21 , ie, greater than the maximum front-rear width of the protrusion 21 . The left-right width of the receiving portion 63 is set larger than the diameter of the head portion 23 of the protruding portion 21 , that is, larger than the maximum left-right width of the protruding portion 21 . The receiving portion 63 allows the protruding portion 21 to be inserted downward from above until the protruding portion 21 reaches a position below the first rail portion 61 and the second rail portion 62 . The position of the receiving portion 63 is indicated to the user by the marking portions 57 provided on the left and right side surfaces of the first guide portion 50 (see FIGS. 4 , 8 , and 9 ), thereby facilitating alignment when assembling the auxiliary arm 10 . In other words, the marking portion 57 is provided at a position that can be visually recognized from the outside of the first guide portion 50 and corresponds to the position at which the receiving portion 63 is provided (indication is displayed).

That is, the groove widths of the first rail portion 61 and the second rail portion 62 are such that the neck portion 22 of the protruding portion 21 can penetrate but the head portion 23 cannot penetrate. After the protruding portion 21 has been inserted into the receiving portion 63 from above, if the neck portion 22 is placed on the guide rail of the first guide rail portion 61 or the second guide rail portion 62 with the head portion 23 located at a lower position than the guide rail, If the slot is inserted, the movable fitting 20 is connected to the base fitting 40 to slide and move freely, and the movable fitting 20 will not fall off in the up and down direction.

In addition, the first rail portion 61 has a pair of elastic protrusions 64 on the opposite surface of the groove. The elastic protrusion 64 is aligned with the elongated side (the positive side of the X-axis) of the neck 22 of the protruding part 21 when the protruding part 21 is located at the accommodation position P1 corresponding to the limit position of the retracted side (shown in a dotted circle in FIG. 6 ). ) is protrudingly arranged in a position directly in front of the storage position P1 in such a way that the surface is closely attached. The protruding portion 21 can move over the elastic protrusion 64 to the accommodation position P1 by elastically deforming the elastic protrusion 64 . On the contrary, it is necessary to go over the elastic protrusion 64 again to be pulled out from the storage position P1, and the elastic protrusion 64 functions to keep the protruding portion 21 at the storage position P1.

Similarly, the second rail portion 62 also has a pair of elastic protrusions 64 on the opposite surface of the groove. The elastic protrusion 64 is arranged so as to be on the retracted side (X-axis negative side) of the neck portion 22 of the protruding portion 21 when the protruding portion 21 is located at the extended position P2 (shown in a dotted circle in FIG. 6 ) as the limit position of the elongated side. The surface is protrudingly arranged in the position directly in front of the extended position P2 in a close-fitting manner. The protruding portion 21 can move over the elastic protrusion 64 to the extended position P2 by elastically deforming the elastic protrusion 64 . On the contrary, it is necessary to go over the elastic protrusion 64 again to pull out from the extended position P2, and the elastic protrusion 64 functions to keep the protruding portion 21 at the extended position P2.

Focusing on the respective guide ranges of the first guide part 50 and the second guide part 60, the guide range W1 of the first guide part 50 is set to be larger than the guide range of the second guide part 60 on the retracted side (X-axis negative side). W2 is wide, but conversely reaches just before the extended position P2 on the extended side (X-axis positive side). In other words, one end portion on one side in the telescopic direction does not have the guidance of the first guide portion 50 but has the guidance of the second guide portion 60 .

Therefore, when the movable fitting 20 is completely pulled out from the base fitting 40 to extend the auxiliary arm 10 to the maximum extent, the protruding portion 21 of the movable fitting 20 reaches the extended position P2, and the movable fitting 20 is not guided by the first guide. The portion 50 maintains a posture so as to be able to swing about the axis AX2 relative to the base metal fitting 40 .

In addition, when the protruding portion 21 of the movable fitting 20 reaches the extended position P2, the protruding portion 21 is held at the extended position P2 by the action of the elastic protrusion 64 . Accordingly, when the user performs a swing operation, the movable fitting 20 does not deviate in the retraction direction, and does not come into contact with the first guide portion 50 again, making it difficult to perform the swing operation. In addition, when the extended position P2 is reached, the elastic projection 64 presses the neck portion 22 to fasten it, thereby generating moderate friction (torsion resistance) between the protruding portion 21 and the second guide portion 60 to maintain the swinging position. Relative poses of the movable fitting 20 and the base fitting 40 . The extended position P2 is a position that should also be called a bearing portion for the protruding portion 21 .

Similarly, when the movable fitting 20 is completely pushed in from the base fitting 40 to retract the auxiliary arm 10 to the maximum extent, the movable fitting 20 will be closed from the time the protruding portion 21 of the movable fitting 20 reaches the accommodation position P1. The posture is held by the first guide part 50 and cannot swing relative to the base attachment 40 .

Moreover, when the protrusion 21 of the movable fitting 20 reaches the storage position P1, the protrusion 21 is held at the storage position P1 by the action of the elastic protrusion 64 . When kept at the receiving position P1, the neck 22 is fastened by the elastic protrusion 64, thereby generating moderate resistance between the protruding portion 21 and the second guide portion 60, so that the movable fitting 20 is kept contained in the base fitting 40. state.

The third guide portion 70 is a wall portion protruding downward from the lower surface on the front side of the base metal fitting 40 , and has a substantially horseshoe shape when viewed from above. Furthermore, the retracted side of the third guide portion 70 reaches the position where the left and right sides of the receiving portion 63 of the second guide portion 60 are located. The left and right internal dimensions of the third guide portion 70 are set to be slightly larger than the diameter of the head portion 23 of the protruding portion 21 .

FIG. 9 is a perspective view for explaining assembly and expansion and contraction of the auxiliary arm 10 . In addition, for ease of understanding and for convenience, the base metal fitting 40 is cut and shown in an XZ cross-section.

The user uses the marking portion 57 as a reference for position alignment, specifically, after the protruding portion 21 is located directly above the positive side of the Z-axis of the marking portion 57, the protruding portion 21 of the movable accessory 20 is directed from above. The receiving portion 63 of the second guide portion 60 is inserted. The user can know the insertion limit by bringing the lower surface of the portion of the movable metal fitting 20 having the concave portion 24 into contact with the upper surface of the second rail portion 62 of the second guide portion 60 .

At this time, the protruding portion 21 inserted into the receiving portion 63 is not engaged with any one of the first rail portion 61 and the second rail portion 62, but the outer surface of the head portion 23 is held by the third guide portion 70. The inner surface restricts lateral movement (movement in the Y-axis direction) and guides it in the telescopic direction (X-axis direction). Therefore, if the user slides the movable fitting 20 while maintaining the guide to make the protruding part 21 go in the direction of extension (X-axis positive direction) or retraction direction (X-axis negative direction), the protruding part 21 and the first guide rail will Either one of the rail portion 61 or the second rail portion 62 is engaged to complete the connection. The movable metal fitting 20 is in a form in which the head portion 23 of the protruding portion 21 protrudes from the housing space of the base metal metal 40 .

When the connection is completed, the elastic protrusion 51 protruding from the inner surface of the first guide portion 50 has the same height as the concave portion 24 of the movable metal fitting 20 . When the movable fitting 20 is slid in the telescopic direction, the elastic protrusion 51 will go over the partition between the adjacent recesses 24 while being elastically deformed, so that the sliding operation of the movable fitting 20 will produce a moderate sense of operational resistance and improve the operating feeling. the quality of. In addition, the resistance when the elastic protrusion 51 passes over while being elastically deformed acts to maintain the current position of the movable metal fitting 20 relative to the base metal metal 40 .

When the movable fitting 20 is extended or contracted, the protruding portion 21 passes through the receiving portion 63 . In the receiving portion 63, there is no structure corresponding to the rail portion that sandwiches and guides the neck portion 22 of the protruding portion 21 like the first rail portion 61 and the second rail portion 62, so it may look protruding at first glance. The part 21 cannot move smoothly between the first rail part 61 and the second rail part 62 . However, since the head portion 23 of the protruding portion 21 is guided by the third guide portion 70 while passing through the receiving portion 63 , it can smoothly slide and move between the first rail portion 61 and the second rail portion 62 .

As described above, according to the present embodiment, it is possible to realize an accessory connection structure with a smaller number of components than in the past, and a flexible and bendable accessory connection structure. Only two accessories can be used to realize the connection structure of accessories that can be stretched and bent. Compared with the connection structure of the conventional three-piece structure, the structure is simple and simple, the assembly is also easy, and the manufacturing cost can be suppressed.
