Description

Walking stick

Technical field

The present invention relates to a kind of walk helper, i.e. walking stick.

Background technology

A kind of walk helper, as walking stick, comprise linear or the rectilinear cane body of cardinal principle, its one end is comprise the upper end holding support section, and the other end is the lower end being provided with antislip metal packet header.

Walking stick mainly contains two shortcomings, and the first needs when walking stick falls to bend over to be picked up from ground, is if user does not want to allow it fall on ground on the other hand, vertical plane must be found to support by it.

Current known walking stick comprises, and lower end ferrule it has discoid widening, and this disk is coaxial with walking stick, to form a lever, when such walking stick is applied on this disk with substantially vertical pressure on the ground, walking stick can be made to rebound.

But the shortcoming of this kind of walking stick is, during whole operation, need crucial applying power or control, so that walking stick rebounds, but the upright process of walking stick is suddenly, fast, user may catch when it uprightly rises, and great majority need the people of walking stick all handicapped.

Another known walking stick comprises the parts that the walking stick moment is kept upright, as the walking stick described in EP 0661010.The lower end of this walking stick is provided with an element, and this element has in bottom surface and periphery the convex surface defining the point of rotation, and meanwhile, owing to there being a briquetting, the center of gravity of walking stick is positioned at the below of this point of rotation.

Such walking stick can uprightly rise voluntarily, and the moment keeps plumbness.But practice confirms, the size bottom it makes it lose the practicality of basic function, as helped walking.

Another known walking stick has the stability can guaranteed in use, can make its position of being kept upright without the need to any support.This kind of walking stick, described in US 5992434, FR 2668690, DE 20309568 and WO 99/35930, comprise the ferrule with stop plane that end is arranged, this plane is vertical with the main shaft of walking stick.

Although the walking stick described in these files has following feature: stability when walking stick uses can be guaranteed on the one hand, guarantee that however, they still have shortcoming without the need to supporting position of can being kept upright on the other hand.In fact, when plan pin erect walking stick or without the need to supporting be kept upright time, its planar base surface requires that action when operation is very accurate, so that this planar base surface can kiss the earth completely, avoids rocking etc. and causes inclination.

Summary of the invention

The object of the present invention is to provide a kind of walking stick that can overcome above-mentioned various shortcoming.

Walking stick of the present invention comprises: a linear or substantially rectilinear cane bar, one comprises the upper end holding support handle, one is provided with the lower end in antislip metal packet header, it has discoid widening, described disk is coaxial with walking stick, to form a lever, can rebound after applying pressure thereon, it is characterized in that, described cane bar and described handle all adopt light material to make, described ferrule comprises a briquetting, make the center of gravity of walking stick as far as possible near lower end, and described ferrule has convex end wall.

Center of gravity is arranged at close to lower end as far as possible, then in conjunction with discoid ferrule, rebounds after making walking stick can be applied with pressure on the edge of ferrule, the applying power without the need to key or the specific control to this power.

When walking stick is put on the ground, center of gravity cannot make walking stick automatically rebound because of low not, but enough low to assist to rebound walking stick, to guarantee to rebound with certain tilt angle relative to horizontal line, guarantees stability when vertically placing further.

Compare and can only have a settling position and the described position difficult planar base surface looked for often, the convex of the end of ferrule is by providing multiple settling position to slow down small spring action.

According to another feature of walking stick of the present invention, the end wall of ferrule is spherical cap.

According to a feature again of walking stick of the present invention, ferrule has the peripheral wall of the diminishing truncate shape to end.

According to the another feature of walking stick of the present invention, the top edge of peripheral wall is connected with cane bar by horn-like mid portion.

From the angle manufactured, cane bar and handle adopt composite to make, and are fibre reinforced plastics, as glass fiber reinforced polycarbonate.

Ferrule adopts cast iron to make, the briquetting that formation is wrapped up with elastomer, but better and more favourable way is, briquetting is made up of the battery for the electronic installation of operation setting on walking stick, as location and/or counting equipment.

Hereafter by explanation, and coordinate and represent the accompanying drawing of non-limiting example, allow the advantage of walking stick provided by the invention and feature clearly.

Detailed description of the invention

As shown in Figure 1, mainly comprise a linear or substantially rectilinear cane bar 10, upper end be made up of hook-shaped handle 11 according to walking stick 1 of the present invention, and a ferrule 2 being arranged on lower end 12.

Ferrule 2 is coaxial discoid with cane bar 10, and its diameter is more much larger than cane bar 10, to strengthen circumferential area as far as possible, plays the effect of lever.

As shown in Figure 2, the lower end 12 of walking stick 1 and the detail of ferrule 2 can be seen.

Ferrule 2 has the end wall 20 of slight bending, for having the spherical cap compared with larger radius of curvature, peripheral wall 21 is diminishing truncate shape to end, and namely the top edge 23 of peripheral wall 21 forms a circle, and its diameter is greater than the diameter of a circle that this wall lower edge 24 is formed.

Further, the coupling part between the top edge 23 of peripheral wall 21 and cane bar 10 is horn-like mid portion 25.

Ferrule 2 is formed primarily of the briquetting 3 of parcel one deck elastomeric material 22, namely forms wall 20,21.

Briquetting 3 is for being reduced to lower end 12 as far as possible by the center of gravity of walking stick 1.Briquetting can by metal material as cast iron forms, the battery of the electronic installation preferably adopting walking stick to carry.

In fact, walking stick positioner, alarm signal dispensing device or other various measurement mechanism can be provided, as pedometer, in walking stick.

With reference to figure 3a, 3b, 3c and 3d, the purposes of visible each feature of walking stick 1 of the present invention.

Visible in figure, when pressure P applies, as with pin, time on ferrule 2, use the latter as lever, the lower end 12 of walking stick 1 is in the situation of its three successive stages rebounded.

As shown in the figure, the center of gravity G of walking stick 1 is positioned at the height of cane bar 10 near lower end 12, and the position of this center of gravity G is certainly depended on and the length of cane bar 10 also depended on the material of cane bar 10 and handle 11, and the size of unshowned briquetting 3 and character.

In Fig. 3 a, walking stick 1 is by being placed on the S of ground, and 11(is not shown at its upper end) and ferrule 2 between, or more specifically, the corner angle point formed at edge 23.

In Fig. 3 b, by applying pressure P at the top of ferrule 2, at the height of the part at the part contacted with ground S edge 23 diametrically, cane bar 10 is risen by leverage.

By by ferrule 2 along edge 23 axial-rotation, until the ferrule 2 in the first stage props up ground S by its peripheral wall 21, realize rebounding.

In Fig. 3 c, by applying pressure P, make the corner angle axial-rotation that cane bar 10 is formed along edge 24, and then cane bar 10 continues to rise, until wall 20 kiss the earth S, as shown in Figure 3 d.

Center of gravity G is arranged at and makes walking stick 1 be easy to handle near ferrule 2, and applied pressure minimizes, thus reduce cantilever impact, be convenient to the control promoted.

It should be noted, horn-like mid portion 25 provides and applies the certain comfortableness of pressure P with pin.

Further, due to the setting of the position of center of gravity G and the larger radius of curvature of wall 20, therefore walking stick 1 without the need to any surface against protecting upright position.

The convex of wall 20 can make walking stick 1 be stabilized in the position of balance, and does not necessarily correspond to the up rightness of cane bar 10.

Therefore, a little after training, the walking stick of the present invention 1 fallen on ground just can rebound by user, makes it in vertical position, and holds it in this position, and for the user without the need to operating with hand.
