It is a front view of the connector which concerns on this invention. It is a top view of the connector of FIG. It is sectional drawing of the clip body in the connector of FIG. It is sectional drawing of the clamp body in the connector of FIG.

Embodiments of the present invention will be described with reference to the drawings.
The connector 1 is a connector 4 that connects the clip body 2 that grips the supported body A, the clamp body 3 that grips the support body B, and the clamp body 3 and the clip body 2 at a predetermined interval. And. Whether the clip body 2 or the clamp body 3 grips the support body B or the supported body A can be appropriately selected.

The clip body 2 includes first and second clip pieces 21 and 22 that are pivotally attached to each other.

The first clip piece 21 includes a clip piece main body 211 and a female screw type connecting member 212 for connecting the connecting body 4. The female screw type connecting member 212 is rotatably connected around the axis to the connecting portion 213 on the base end side of the clip piece main body 211. A pivoting portion 214 with the second clip piece 22 is provided in the middle portion of the clip piece main body 211, and a grip portion 215 is provided on the tip end side. The grip portion 215 is coated with vinyl chloride.

As shown in FIG. 3, the connecting portion 213 is formed by a connection hole 213a opened to the proximal end side, a spring receiving projection 213b protruding from the center of the bottom surface thereof, and a plurality of connecting portions 213 formed at radial intervals on the bottom surface. It has an engaging protrusion 213c.

The female screw type connecting member 212 includes a boss portion 212a that penetrates the spring receiving projection 213b and is rotatably fitted to the connecting hole 213a around the axis, and a flange portion 212b that extends outward from the connecting hole 213a. A plurality of engaging protrusions 212c that engage with the engaging protrusions 213c are formed on the end surface of the boss portion 212a. At the center of the collar portion 212b, a female screw portion 212d that opens to the proximal end side is formed.

The spring 213d is locked to the outer circumference of the spring receiving protrusion 213b protruding into the boss portion 212a. The spring 213d pulls the boss portion 212a into the connecting hole 213a and presses the engaging projections 213c and 212c so that the female screw type connecting member 212 rotates about the axis of the main body 211 at predetermined angles (for example, 30 °). Apply a rotational load.

The second clip piece 22 has a pressing portion 221 for opening and closing operation with the first clip piece 21 on the base end side, a pivoting portion 222 in the intermediate portion, and vinyl chloride on the tip end side. It has a coated grip 223.

The first clip piece 21 and the second clip piece 22 are pivotally attached by a pivot pin 24 via a spring 23 at the pivoted portions 212 and 222, and the supported body A is repelled between the gripped portions 215 and 223. Start and grip.

As shown in FIG. 4, the clamp bodies 3 include first and second clamp pieces 31 and 32 pivotally attached to each other by pivot pins 33 so as to grip the support B between them, and both clamp pieces 31. A tightening member 34 for tightening between 32 and 32 so as to be openable and closable is provided.

The first clamp piece 31 has a female screw type connecting portion 311 and a pivoting portion 312 for connecting the connecting body 4 on the base end side, and has a grip portion 313 in the middle and an engagement with the tightening member 34 at the tip portion. It has a part 314. The tip of the engaging portion 314 is bifurcated to form a pair of bearing portions 314a.

The second clamp piece 32 has a pivoting portion 321 on the proximal end side, a gripping portion 322 in the middle, and an engaging portion 323 with a tightening member 34 at the tip end portion, and is clamped by a pivot pin 33 at the pivoting portion 321. It is pivotally attached to the pivotal portion 312 of the piece 31. The engaging portion 323 has a split groove 323a open on the tip end side.

The tightening member 34 includes a nut pin 341 and a thumbscrew 342. The nut pin 341 is rotatably supported around the axis by the bearing portion 314a at both ends, and has a screw hole 341a penetrating in the direction orthogonal to the axis in the middle. The knob screw 342 includes a screw rod portion 342a and a knob portion 232b, and the screw rod portion 342a penetrates the screw hole 341a of the nut pin 341. Therefore, the pinch screw 342 swings around the axis of the nut pin 341 between the tightening position where the screw rod portion 342a engages with the split groove 323a and the release position where the screw rod portion 342a disengages from the tightening position. If the knob screw 342 is tightened at the tightening position, the support member B can be gripped between the clamp pieces 31 and 32.

In the illustrated embodiment, the connecting body 4 is a male screw type connecting portion screwed into the female thread type connecting portions 212 and 311 of the clip body 2 or the clamp body 3 at both ends of the main body 41 made of a flexible pipe such as a coolant pipe. 42, 43 are provided. The main body 41 may be a straight pipe, and may have any shape and length.

For example, if the clamp body 3 grips the support pipe B of the walking assist device and the clip body 2 grips the pole A of the drip stand to be moved together with the walking assist device, the walking assist device and the drip stand can be easily connected. it can. If the rotation angle around the axis of the clip body 2 and the connecting body 4 is changed in the female thread type connecting member 212, the pole A and the support pipe B can be reliably connected to each other regardless of the relative angle. Can be done.

The support body B and the supported body A are not limited to the components of the walking aid and the drip stand.
