Description

Inflator

The present invention relates to a kind of as claim 1 inflator as described in the preamble.

Bicycle pump is adapted to be fixed on the cycle frame Anywhere.Yet the shortcoming of doing like this is: easily stolen on the one hand, on the other hand through regular meeting from for this reason and the retaining member that is provided with comes off.So possibility of having sought to lay preferably inflator soon.Wherein a kind of may be that inflator is placed in the vehicle seat supporting member of bicycle or in the saddle tube.For inflator is fixed on the there, at the local development of being mentioned various technology.A kind of inflator that replaces the vehicle seat supporting member and removably be connected with vehicle seat by screw thread has for example been described in US 5 499 858.Inflate operation for execution, vehicle seat taken off from saddle tube together with inflator, and its tipping is come, be about to vehicle seat and place on the ground, in view of the above vehicle seat in the process of inflating simultaneously as bottom bearing member.But the shortcoming of this device existence is that vehicle seat will be made dirty in the process of inflating on the one hand, on the other hand because vehicle seat and inflator link together device use inconvenience.Also described a kind of similar device in US 5 324 174, it also forms a single piece with saddle springs.In addition, maximum shortcoming is that they must carry out adaptively separately with each bicycle in all these inflators, and can not be common to the bicycle and the vehicle seat of all common type.

In addition, except being seated in inflator on the bicycle, putting other the little articles for use as instrument, repairing articles for use or replacement part and when putting the personal effects, also going wrong.Those article of mentioning in order to put are typically provided with so-called vehicle seat bag, so, as those complete easy stolen inflators because the outside can see its placement, the article in the vehicle seat bag are also easily stolen, because each stealer just can be clear that the vehicle seat bag from the outside at a glance.Also attempt the possible scheme of the placement article seeking to improve for this reason.DE 44 20 170 discloses the body that holds of a kind of maintenance supply that is used for being seated in the bicycle support column and instrument.This holds body and has hole and the cavity that is used for place tool and tyre repair articles for use, and it is installed on the vehicle seat supporting member also clamped.This clamping is to be screwed in this internal thread that holds body by the lid that this is held body, so-called lock(ing) bolt to realize.Lock(ing) bolt is designed to taper, thereby can will hold the interior pipe of the wall pressure of body to the vehicle seat supporting member.In addition, can in groove, lay stop endwisely slip, the rubber-like ring.For the diameter that holds body is increased, because for held stationary must apply sizable power, be difficult so will hold by the bolt rundown process that body is fixed in the vehicle seat supporting member.In addition, mounting or dismounting tools to hold body also very complicated, need certain muscle power, and the required comparatively speaking time is also very long.

Therefore, the technical problem to be solved in the present invention provides a kind of inflator, and it can be placed in the vehicle seat supporting member of bicycle easy, fast and reliably, and the precondition of placing a whole set of tire fault maintenance supply is provided.

Above-mentioned technical problem can be solved by the described inflator of claim 1.The technological scheme of dependent claims has provided preferred expansion design.

Inflator of the present invention has deformable piece between the outlet valve that cylinder reaches with cylinder is connected movingly.The diameter of this deformable piece is variable big with respect to the motion of cylinder by outlet valve.When the longitudinal axis of the longitudinal axis of cylinder and outlet valve was 90 ° at an angle, especially each other, this deformable piece was in not pressurized (entlasten) state.For example can finish the process of inflating in this position.For inflator being laid and is locked in the vehicle seat supporting member, inflator of the present invention is done the leading hole that enters into an end relative with vehicle seat of vehicle seat supporting member or enter this end just with its handle.At this moment, the inflator major part that always enters into deformable piece is positioned at the inner part of vehicle seat supporting member.By making outlet valve upset (Umklappen), the longitudinal axis of the longitudinal axis of cylinder and outlet valve is extended parallel to each other or overlapping, deformable piece is compressed, make the enlarged diameter of deformable piece.Described diameter can be increased at least and conform to the internal diameter of vehicle seat supporting member this moment.So, inflator is fixed and is clamped in the inside of vehicle seat supporting member, thereby can be easy and apace inflator is locked in the vehicle seat supporting member, because just enough for realizing the less power of these need under leverage.Because described deformable member can be out of shape, it can be close on the vehicle seat supporting member, and is not subjected to possible Roughness or the accurately influence of moulding.Because this fixing special-purpose screw thread that do not need, can make the general ground of inflator and almost irrespectively come into operation with the diameter of vehicle seat supporting member.Therefore, this inflator needn't match with the vehicle seat of special manufacturing is specific, and almost can match with all common vehicle seats.As deformable piece for example can be the caulking gum of rubber washer form, perhaps also can be deformable soft plastic spare.

In addition, the handle design of inflator can also be become the maintenance tool of bicycle.For this reason, can not adopt inflator handle commonly used, and adopt two tool rods that removably are connected with piston rod.As another mode of execution, instrument is enclosed within on the handle of piston rod and and removably is connected with the cylinder of inflator.Inflator but also also have instrument all to be placed on the inside of vehicle seat supporting member so not only in the mode of compactness.In addition, instrument still can also be given over to handle in the mode of handle case, this is very favourable to the occasion of using this instrument need spend than great strength.Be very favourable for example making like this of the situation of tool rod detaching tyre.

At last, a columnar container removably can also be connected with outlet valve.This for example can be by being threaded or plug-type connects and realizes.The cylindrical vessel of this tubular type or cup type shape can be placed various article, for example instrument, replacement part, maintenance supply or similar goods.So, these article can be kept in the frame tube of bicycle reliably.

Below in conjunction with accompanying drawing the present invention is done detailed explanation and description:

Fig. 1 shows the partial sectional view of an embodiment of the present invention;

Fig. 2 shows and is assembled in mode of execution in the vehicle seat supporting member, shown in Figure 1.

Especially as can be seen from Figure 1, inflator 1 of the present invention also has all parts of conventional inflator.Thereby it is provided with pump-cylinder 2, and the piston of piston rod 3 (not being shown specifically among the figure) can move in cylinder.For making piston motion be provided with handle 4.In addition, be provided with the outlet valve 5 that is connected in the mode of shown in arrow among the figure 10, swinging like that or flap moves with cylinder 2.According to the present invention, between cylinder 2 and outlet valve 5, be provided with deformable piece 6, especially be provided with caulking gum.Learn that inflator 1 can be placed in the vehicle seat supporting member 50 and coupled by Fig. 2.Inflator 1 is done the leading hole 52 vehicle seat supporting member 50, relative with vehicle seat 51 that enters into its handle 4.This proceeds to as shown in Figure 1 state till deformable piece 6 is positioned at vehicle seat supporting member 50 inside at least just always.

By outlet valve is turned over like that down shown in arrow among Fig. 1 10, deformable piece 6 is deformed, so that its diameter increase, resemble longitudinally it is extruded together.Deformable piece 6 longitudinally shorten (by line segment I ' and I " expression) correspondingly played the effect that strengthens its diameter (by d ' and d " represent).After the diameter d ' change greatly of deformable piece 6, " inside diameter D with vehicle seat supporting member 50 is corresponding at least for its diameter d.So, inflator 1 reliably and safely is clamped at the inside 53 of vehicle seat supporting member 50.

In order from vehicle seat supporting member 50, to take out inflator 1, outlet valve 5 is turned to position shown in Figure 1 to returning.As from the comparison of Fig. 1 and Fig. 2, can learning, when the longitudinal axis of the cylinder of representing by dot and dash line A 2 substantially with the longitudinal axis a of outlet valve 5 when perpendicular, deformable piece 6 is pressurized not once more.If outlet valve 5 is rotated around articulating point 7 along arrow 10 directions, then longitudinal axis A and a extend parallel to each other substantially or overlap each other.Thereby reach clamped condition shown in Figure 2.

For deformable piece 6 is vertically shortened and enlarged diameter, with an end 8 designs conglobate end opposite of outlet valve 5 with exhaust end 9.At this moment, the distance of the outermost end points 11 of end 8 and articulating point 7 is greater than the distance of side 12 with the articulating point 7 of outlet valve 5.Therefore, by along the moving of the direction of arrow 10, the distance between deformable piece 6 and the articulating point 7 becomes big, thereby deformable piece 6 is pressed together.

After inserting inflator 1 in the vehicle seat supporting member 50, as shown in arrow 61 inflator 1 and vehicle seat supporting member 50 are inserted in the vehicle frame pipe 60.By known possible means of fixation, quick securing means for example, use a burglarproof lock in case of necessity, vehicle seat supporting member 50 is fixed in the vehicle frame pipe 60 in a usual manner.At this moment, inflator 1 is positioned over the inside of bicycle reliably in invisible mode.For taking off inflator 1, as long as vehicle seat supporting member 50 is taken off from vehicle frame pipe 60 together with vehicle seat 51, and upset outlet valve 5, deformable piece 6 is unclamped, from clamped condition so desirable gas outlet 1.

In mode of execution shown in Figure 1, handle 4 is designed to the rod handle of instrument 30,31.

30,31 forms with handle case are retained in the there as handle 4.If tool using 30,31, it can be unloaded and come into operation from piston rod 3.As a kind of substitute mode,

instrument

30,31 can also be enclosed within on piston rod 3 extension devices as the handle of operated piston bar 3, and removably be connected with the cylinder 2 of inflator 1.This for example can removably connect by be arranged on screw thread on the cylinder 2 (be clearly shown that and represent with reference character 14) in Fig. 2.In this case,

instrument

30,31 can take off from inflator 1, thereby can inflate operation.

As another kind of substitute mode,
