Description

The walking stick that castor is arranged

Technical field

The present invention relates to the walking stick of castor.

Background technology

General employed walking stick, the lower end does not have castor.This walking stick is when walking is advanced, and need break away from ground to the lower end could forwards move.Can not body support when this walking stick breaks away from ground in the lower end, so the shortcoming of body support is continuously arranged.If fix castor, just do not need to make the lower end to break away from ground, body support continuously in the lower end of walking stick.But in the lower end of a walking stick fixing on the structure of castor, can make the lower end of walking stick because slide in the front and back of castor body support stably.Topple over the front and back of walking stick, can adopt the pattern of driving the carrier that flat 10-86824 communique (patent documentation 1) put down in writing such as the spy, castor 130 is set in front and back solves.This carrier can use under state illustrated in figures 1 and 2 by changing the direction of castor 130.When this carrier uses under state shown in Fig. 1, can replace walking stick to use.But the easy swaying style of the carrier of this structure, have can not the stable support health shortcoming.For energy stable support health, the support bar 131 of castor 130 is being fixed in stable lower end, and it is very important making its self-support.The replacement walking stick instrument of body support firmly also can use walker.General employed walker is because greatly, but use occasion is restricted.The walker of small portable is opened flat 9-38161 communique (patent documentation 2) the spy and is put down in writing to some extent.The walker that this communique is put down in writing becomes the lower end of the framework 332 of " コ " font, fixing last 4 castors 330 in complications as shown in Figure 3.For framework 332 is supported oneself, fix the foot rest 333 of extending transversely in the lower end of framework 332, in the two ends of foot rest 333 rigid castors 330.

Te Kaiping 10-86824 communique

Te Kaiping 9-38161 communique

The walker of being put down in writing in this communique as shown in Figure 3 and Figure 4, links in the foldable chair 334 in the middle of framework 332, on one side link basket 335 on top.The walker of this structure is by the body support that comes of the framework 332 of supporting oneself with four castors 330.And because be provided with basket 335, can pack basket 335 in addition and the advantage of carrying easily.It is outstanding that but the basket of this walker 335 has from the side of framework 332, the shortcoming that banner is excessive.And there is basket 335 to adorn heavy thing later on also easily to sideways.In order to eliminate shortcoming, if foot rest 333 lengthenings that are fixed on framework 332 lower ends, can make that banner increases all the more, use occasion is restricted.And the occasion use that as far as possible reduces walking stick is important.This is that the user's of walking stick sphere of action just can be restricted so because if the field of employment of walking stick is restricted.If the user's of walking stick sphere of action is without limits, and walking stick just can carry in the vehicles such as electric car, aircraft, and this point is even more important.Therefore, this just requires to be easy to miniaturization in carrying the time, can stablize body support firmly in use.But stable support health and integral miniaturization and do not have the restriction of field of employment are two opposite characteristics, and it is extremely difficult to satisfy both simultaneously.

The present invention is that purpose is developed to solve this shortcoming.Free-revving engine of the present invention is, the walking stick that castor is arranged minimum the restriction of integral miniaturization, use occasion and can the stable support health is provided.

In addition, another one free-revving engine of the present invention is the walking stick that castor is arranged that also can stably move giocoso when being provided at the loading state.

To make above-mentioned purpose that introduce and more of the present invention and feature by detailed description with reference to the accompanying drawings, become more clear.

Summary of the invention

Of the present invention have the walking stick of castor to be equipped with: the handle two ends that horizontal direction prolongs be connected with telescopic vertical rod the walking stick main body, be connected this walking stick main body lower end and make rectangular horizontal microscope carrier that vertical rod supports oneself, on horizontal microscope carrier, load removably suitcase by the castor that is fixed on four jiaos of lower surfaces.Being contained in the castor of four jiaos of horizontal microscope carriers, is to be external diameter that the wheel of 30～60mm is contained on the horizontal microscope carrier, so that its rotating shaft can rotate in horizontal plane, moving direction can be moved freely in horizontal plane; The walking stick main body with the attitude of handle along the length direction prolongation of the horizontal microscope carrier of rectangle, is fixed on the lower end of vertical rod at the two ends on the one-sided long limit of the horizontal microscope carrier of rectangle.

And, the walking stick that castor is arranged of the present invention is rectangular one-sided crooked or tilt towards the approaching direction of horizontal microscope carrier middle position from what fixed its lower end the handle of the upper end that is connected vertical rod; Perhaps,, be provided for the protuberance of rigid castors, castor be set, the handle of walking stick main body is set between the castor of both sides at the lower surface of protuberance in the horizontal microscope carrier side of having fixed vertical rod.

Handle under the vertical rod contraction state, can be configured in suitcase above.The horizontal microscope carrier of rectangle wide can be 10～25cm.And the length of the horizontal microscope carrier of rectangle is bigger than width, can be 22～50cm.

The above-mentioned walking stick integral miniaturization that castor is arranged, but the restriction of field of employment is few, and have the stable characteristics of body support firmly.Particularly the lower end of walking stick is moved by castor, must break away from ground, have the advantage that connects stable support health unlike general walking stick lower end.Walking stick of the present invention is connecting the walking stick main body lower end of vertical rod to the handle two ends, is connecting rectangular horizontal microscope carrier; Load on this horizontal microscope carrier removably in the suitcase, at its Corner Strapped the profile of making being arranged is the castor that the wheel of 30～60mm can rotate freely in horizontal plane; And the handle of walking stick main body is fixed on the lower end of vertical rod at the two ends on the one-sided face length limit of rectangular horizontal microscope carrier in the attitude that prolongs along rectangular horizontal microscope carrier length direction.This vertical rod, crooked or tilt to making handle be in the locality of horizontal microscope carrier central authorities, perhaps, outstanding part is set in the side of horizontal microscope carrier, at this castor is set, handle is configured between the castor of both sides.Especially, the walking stick of this structure, because vertical rod is when being connected horizontal microscope carrier side, handle is configured in the centre of the set castor in the both sides of horizontal microscope carrier.So even vertically squeeze grip can not crawled (word advance) yet, has in supportive body the advantage that can move to choice direction.

adopts expansion link

5A, 65A, a 75A to extract the two-stage structure that inserts out in

guide cylinder

5B, 65B, 75B.But, vertical rod also can adopt five segment structures of setting up intermediate bar between expansion link and guide cylinder.Though this vertical rod is diagram not, can extract intermediate bar out insert ground insertion guide cylinder five segment structures can adopt to extract expansion link out when inserting ground and insert intermediate bar.The vertical rod of five segment structures inserts guide cylinder to expansion link and intermediate bar, when handle is in extreme lower position, can shrinks the miniaturization of walking stick main body and reduce height.Therefore this walking stick can reduce the height that is contained in the suitcase on the horizontal microscope carrier, makes integral miniaturization.Falling under the state of handle like this, the walking stick of integral miniaturization can be carried very satisfactoryly.

Expansion link

5A, 65A, 75A stop decline with retainer when mentioning the extreme higher position.Retainer can make

vertical rod

5,65,75 use in all structures that the position of mentioning stops.Make the retainer of expansion link 5A when mentioning the extreme higher position and stop as shown in figure 10.Retainer 18 among this figure is made up of three parts: the resilient projection 19 that give prominence to radial direction elasticity expansion link 5A inside, release this resilient projection 19 spring 20, accommodate the pipe 21 of spring 20 and resilient projection 19.Resilient projection 19 is subjected to the pushing of spring 20, and is outstanding to radial direction from the through hole 22 of expansion link 5A, inserts set stop aperture 23 among the guide cylinder 5B.Resilient projection 19 is set at the lower end of expansion link 5A, and stop aperture 23 is opened on the upper end of guide cylinder 5B.The retainer 18 of this structure, when guide cylinder 5B upwards drew, resilient projection 19 was inserted in the stop apertures 23 automatically at expansion link 5A.Under this state, expansion link 5A guide cylinder 5B relatively descends.When falling expansion link 5A, need push expansion link 5A with strength.Under this state, resilient projection 19 is forced to extrude from stop aperture 23, is in the state that expansion link 5A can descend.

Retainer 18 shown in Figure 10 is mentioned when the highest at handle 4, not special operation, and handle 4 also can stop at that position.In addition, squeeze grip 4 can make its decline with strength.Therefore have the characteristics that the highest position makes its decline again simply of mentioning that simply handle 4 stopped at.,, be known structure but though do not illustrate for retainer, for example, can be at handle setting operation button.The retainer of this structure after handle is mentioned the extreme higher position and stopped, if action button is not operated, just can not be fallen handle.The retainer of this structure, squeeze grip can not descend yet with strength, has the advantages that can firmly rely on when using walking stick.

And retainer 18 also can make the position of handle 4 under being pushed into stop.The retainer of this structure, when handle 4 was received extreme lower position, elasticity was pressed into resilient projection or globule, and stop aperture or recess are set in expansion link or guide cylinder.

Suitcase 3,63,73 can be contained in the size on the horizontal microscope carrier 2,62,72, and promptly the profile of plane profile and horizontal microscope carrier is nearly equal, and is perhaps little than horizontal microscope carrier, perhaps than horizontal microscope carrier big a little.Position when the height of suitcase 3,63,73 shrinks than handle 4,64,74 is also low.Such walking stick when handle 4,64,74 shrinks, can be contained in carrying on the horizontal microscope carrier 2,62,72 to suitcase 3,63,73.

The present invention can implement under the prerequisite of the spirit of the essential characteristic that does not deviate from it in a variety of forms, and present embodiment is illustrative rather than restrictive.Because scope of the present invention is to limit by appending claims rather than by above-mentioned specification, therefore, fall into the interior any remodeling of generally acknowledged scope of appended claims, or all should be considered to be covered by appended claims at the equivalent of this generally acknowledged scope.
