It is just to separate at the coupling position with frame pieces 7 that button is held member 20, and the mat screw is fixed.Again, above pipe portion 18, form cantilever-shaped engaging pawl 22, and, be formed on the inboard of covering portion member 19 with so that this engages the projection 23 of pawl 22 to the interior side direction distortion of pipe portion 18.
To in the position of the projection 23 in covering portion member 19 outsides, be formed with recess 24 relatively, the location that is formed at fastener member 20 arranged with projection 25 in that this recess 24 is chimeric.Again, with the opposition side that engages pawl 22 of pipe portion 18, be formed with recess 26, this recess 26 chimeric have be formed at location that button holds member 20 with projection 27.Be formed with the 18a of section portion of the end of the interior pipe 2 that is inserted in order to acceptance in pipe portion 18 again.
Liner (packing) the 28th, in order to sealed tube portion 18 and cover member 19, and button is held the gap between the member 20.Again, connector 29 is to be connected with distribution mechanism.
Again, shown in Fig. 9 (a), at the leading section of interior pipe 2,8 are formed with connecting hole 30 in the resettlement section.Again, cover member 31 is the openends at outer tube 1, and is used in order to the gap between pipe 2 and the outer tube 1 in sealing.
The telescoping tube of present embodiment suppresses the size of bale packing materials in order to make it when shipment, coupling member 3 is to be pulled down by interior pipe 2.Coupling member 3 is inserted in interior pipe 2, when desiring to finish the combination of telescoping tube, as shown in figure 10, at first, connecting hole 30 under the state of contraposition upward, is inserted in coupling member 3 with interior pipe 2 and makes the front end of interior pipe 2 meet the 18a of section portion of pipe portion 18, then, hold member 20 with the bolting button.
Thus, as shown in figure 11, button is held the projection 23 of the projection 25 pushing covering portion members 19 of member 20, and then the engaging pawl 22 that is pushed by projection 23 is out of shape and the front end of engaging pawl 22 is charged in connecting hole 30, result, pipe 2 front ends in coupling member 3 promptly is fixed on.
One example of operating portion 5 is shown in Figure 12-18.
Be formed with in order to accommodate the segment difference section 1a of fixing operation portion 5 in the inboard of outer tube 1, interior pipe 2 can be inserted to be through at and slightly be retaining member 33 cylindraceous, this retaining member 33 is in order to interior pipe 2 is remained in outer tube 1 this retaining member 33, in forming the portion 34 of having chance with to the end face in segment difference section 1a relatively.Be provided with the liner (packing) 35 that slightly is circular in this edge portion 34, and between liner 35 and segment difference section 1a, be equipped with stopper element 36.
Be formed with to make at retaining member 33 and charge in engaging ditch 9 and the window 39 that the pin 38 of pipe 2 passes through in fixing reaches the moving range in order to restrictions pin 38, and will sell 38 rakes 40 that move to window 39.
Be equipped with the handle member 41 that slightly is circular in the outside of retaining member 33, accommodate pin 38 and in order to the recess 42 of its moving range of restrictions and be formed with, and be provided with to cooperate with wall portion 40a (aftermentioned) of the rake 40 of being located at retaining member 33 and will sell 38 and move to the used rake 45 of window 39 at this handle member 41; This handle member 41 has again and integrally formed this handle member 41 is moved used handle portion 46 to moving direction.
Between handle portion 46 and covering portion member 31, be equipped with handle member 41 is suppressed used spring 47 to the direction of linking part 4 again.Again, at the rake 40 of retaining member 33, with between the regulation aspect every being formed with the vertical 40a of wall portion, at the rake 45 of handle member 41, being formed with the 45a of wall portion becomes the aspect that can connect airtight with the 40a of wall portion.Form fenestrate 41a, 41b in the two sides of handle member 41 again.
8 the openend in the resettlement section, via liner retainer ring 49 fixed-bearings 48, airtight with between the sleeve 12,13 of guaranteeing and being inserted.
So, often by the elastic force pressure of spring 47, as shown in figure 12, with handle member 41 left direction suppress, and be connected under the aspect of the 40a of wall portion of rake 40 of retaining member 33 position of restrictions handle member 41 with the 45a of the wall portion retaining of the rake 45 of handle member 41.At this moment, the pin 38 that is contained in recess 42 is to be tilted the 40a of the wall portion pushing of portion 40 and to move to the direction of window 39, and steps up the rake 45 of handle member 41, charges into arbitrary engaging ditch 9 to interior pipe 2 from window 39, and steps up the flat of handle member 41.
Thus, pin 38 is to be fixed between handle member 41 and the retaining member 33, makes pin 38 link the window 39 of retaining member 33 and the ditch that engages of interior pipe 2, and therefore interior pipe 2 promptly is fixed under this state.Again because of the edge portion 34 of retaining member 33 is connected to the segment difference section 1a of outer tube 1 via stopper element 36 and liner 35 retainings, and opposition side is that the covering member 31 that mat is fixed in outer tube 1 is closed, so retaining member 33 is the openends that are fixed in outer tube 1.Thus, interior pipe 2 is via retaining member 33, and pin 38 and handle member 41 are fixed in outer tube 1.
From this state, when the elastic force pressure that handle portion 46 is being revolted spring 47 moved to the direction of covering portion member 31 of outer tube 1, then the flat of handle member 41 broke away from from window 39, and the i.e. side under window 39 of recess 42, therefore sell 38 and promptly come off, slide rake 45 and move to recess 42 by window 39.
By this, the stationary state of interior pipe 2 promptly is disengaged, and therefore, pipe 2 in can sending from outer tube 1 and can be inserted in outer tube 1 with interior pipe 2, and pipe 2 is from the outstanding overhang of outer tube 1 in can adjusting.
As mentioned above in the present embodiment, because handle portion 46 is integrally formed in handle member 41, can reduces the number of spare parts of operating portion 5, and can reduce the cost, and can improve assembling.The structure of operating portion 5 becomes simple, and compares when constituting operating portion 5 with most parts, positively commence operation.
Owing to connect airtight the 45a of wall portion of the rake 45 of the 40a of wall portion of rake 40 of retaining member 33 and handle member 41, therefore be contained in the pin 38 of recess 42, become from recess 42 step up rake 45 and the motion of pin 38 when reaching till the window 39 to become polar circle sliding, can avoid when the turnover of interior pipe 2 is operated, feeling having the improper phenomenon of resistance etc.
Because of with handle portion 45 same side spring 47 being set, the elastic force pressure of mat spring 47 can prevent with the motion of pin 33 as fulcrum twist grip member 41 grades again.
Now one of the distribution mechanism of present embodiment example is shown in Figure 19 to 22.
In one of coil tension spring 10,11 end, be connected with the lead 14 of the Wiring construction element that becomes linking part 4,15 a wherein side end, and in the other end of coil tension spring 10,11, be connected with the lead 52,53 of the connector contact member 51 of one of the Wiring construction element that becomes linking part 6 key element.
The coil tension spring 10,11st of the main distribution mechanism of pipe 2 in constituting is as Figure 20 (a), (b), (c) shown in, the appearance and size of its central portion forms than cylindrical portion 16a, the slightly little size in footpath within the 16b, and its both ends dwindle gradually and make outermost end form the pushing and drawing shape that continuous most turning minor diameter part is become, and a final circle of end is to curve to hold up 90 degree, connects lead 14 and constitute, 15,52,53 used shackle 10a, 10b, 11a, 11b.Again, lead 14,15,52,53rd is entangled in shackle 10a, 10b, and 11a after the 11b, fixes with scolding tin.
Again, connector contact member 51 and be connected in the shackle 10b of the coil tension spring 10,11 of this connector contact member 51, the end of 11b side is as shown in figure 21, is contained in the lead covering portion 55 of the insertion opening that is formed with connector 29.
Lead covering portion 55 constitutes to have the cell 55a of binding and two cylindrical portion 55b, the shape of 55c, and cell 55a is for accommodating the usefulness with the connected device contact member 51 of connector 29 bindings, and two cylindrical portion 55b, 55c is in order to accommodate coil tension spring 10,11.This lead covering portion 55 becomes to be divided into two halves to thickness direction and can chimeric mutually aspect.
This cylindrical portion 55b, 55c are the cylindrical portion 16a that is inserted in sleeve 16 respectively, 16b.Therefore, the diameter at the both ends of coil tension spring 10,11 is littler than the diameter of central portion, and the size that is differed is equivalent to cylindrical portion 55b, the size of the thickness of 55c.
If with coil tension spring 10,11 diameters to both ends are set as when identical, because of the cylindrical portion 55b of lead covering portion 55,55c is inserted in the cylindrical portion 16a of sleeve 16,16b, therefore, the cylinder 16a of sleeve 16,16b become big footpath person, and at the cylindrical portion 16a of sleeve 16, produce the gap between face and the coil tension spring 10,11 within the 16b.With this structure, interior pipe 2 is extracted out when advancing from outer tube 1, then coil tension spring 10,11 is at cylindrical portion 16a, 16b interior curve and have strong load-carrying to act on its part, thereby when long-time the use, will produce the situation of spring 10,11 broken strings.
At cylindrical portion 55b, 55c is formed with the fixed part 55d in order to fixing cord 52,53, and 55e reaches the flank 55f in order to the end that keeps coil tension spring 10,11, and 55g, this internal diameter size are the sizes that forms the size of the end minor diameter part that meets coil tension spring 10,11. Flank 55f, 55g form and slightly to be the degree of lip-rounding so that under the state of chimeric formation lead covering portion 55, can be formed with the gap on flank 55f, 55g, again, at the cut flank 55h of central portion, 55i, respectively this coil tension spring 10,11 shackle 10b, 11b is inserted in its excision portion, thus, can prevent because of along with coil tension spring 10,11 motion and make shackle 10b, the facts of 11b rotation.
As shown in figure 22, the minor diameter part of coil tension spring 10,11 ends be position at about 4 circles from the end to clamp flank 55f, under the aspect of 55g, be fixed in lead covering portion 55.
