Background technology
The face of shop stone has the slit between paving stone, when illiteracy is not protected (Versiegelung), in the slit, usually form the vegetation of not expecting.Can make the road and the path of shop stone become untidy thus, thereby need to utilize expensive method to attempt to suppress plant (Bewuchs).The device that the face of shop stone is cleaned in known a large amount of different being used to has the brush that is complementary with device, and these devices are applied in the reality.Yet the shortcoming that all solutions have is that it makes that its operation is difficult more and usually causes not satisfied cleaning result in addition.For example problem is, traditional device does not possess such ability, that is, very near-earth perhaps not can be applicable in the path-segments of narrow curve near border stone (Begrenzungsstein).Can confirm in operating aspect, because the high rotating speed of employed driving mechanism and the relative motion that causes thus need very big power consumption and tangible skill, with the cleaning course that utilizes device accurately to expect along expectation or predetermined distance.
File DE 102 47 006 B4 propose, and for being used to clean the device outfit conical gear drive (Winkelgetriebe) of the face of spreading stone, brush dish (B ü rstenscheibe) is attached to this conical gear drive place through driving shaft.Whole transmission mechanism can be around the axis rotation (schwenken) of level, thereby it can be fixed in a plurality of prepositions by the brush dish.The obliquity of attainable thus brush dish is applied to improve to being present in the cleaning in the slit between the paving stone.Yet this solution does not show such possibility,, can be applicable to (randnah) near the edge for example, promptly equally in the zone of border stone or in the path-segments of narrow curve that is.
From file DE 41 35 667 A1, obtain another solution.At this, be provided with single shaft car (Einachser), its pulling is used to clean the device of the face of spreading stone.Thus, the range of application of this device is owing to its physical dimension is limited.
Alternatively, in this document, also mentioned the device of automation (selbstfahrend).At this, be arranged to by the transverse movement of the centrifugal force generation of driving mechanism for balance, utilize prenex adjustment to be arranged in device (nachlaufend) wobble wheel (Pendelrad) of following afterwards.Yet the embodiment of this serious wear is set about (ansetzen) in the result but not reason, thereby can not realize the improvement operated on the whole.In addition, this solution do not demonstrate yet be used near the edge, promptly equally in the zone of border stone or the possible possibility of its application in the path-segments of narrow curve.
At last; Known a kind of brush from file DE 103 32 405 B4, its bristle holder,head (Borstenkopfhalter) have a plurality of connection parts that design (Anschluss) identically and have the bristle head of the bristle that wherein holds to be used for fixing at least one separably by means of the connection of suitable power and/or form fit.According to the disclosure of this document, make the possibility that is connected to become between bristle head and bristle holder,head through dovetail groove profile (Schwalbenschwanzkontur).At this, this dovetail groove profile be used for the bristle head be fixed on bristle holder,head place rather than changeably (that is, change in location ground) hold the bristle head at bristle holder,head place.At this, through this dovetail groove profile only possible be to change the bristle head of wearing and tearing.In order to be suitable for different cleaning requirements, in file DE 103 32 405 B4, propose in addition, a plurality of bristle heads are set, it holds the different bristle that is made from a variety of materials respectively.
Therein, can find out that the shortcoming of this solution does, the bristle head that has assembled can not be matched with pending basis (Untergrund) neatly.What therefore, especially in the basis of alternation, usually be worth expectation is to be designed to different with arrangement the state of bristle head.
Summary of the invention
Therefore, the object of the invention does, a kind of device that is used to clean the face of shop stone is provided, and it becomes shirtsleeve operation maybe and also to can be applicable near the zone that the edge, promptly for example is applied in border stone or in the path-segments of narrow curve.
The present invention utilizes the purpose that realizes proposition according to the characteristic of claim 1.
Other design scheme of the present invention is the object of dependent claims subsequently.
Improve as follows according to the present invention and to have the device of face that is used to clean shop stone that can place brush and the handle of motion through driving mechanism; Promptly; This device has and is equipped with at least one front carriages of taking turns (Vorwagen), and it is being fixed on the device place around the mode of the pivot center rotation of level.
Through this solution,, it realizes the stable and obvious improved manual dexterity property of whole device during using.In addition, because front carriages is installed in the forward part of device, the therefore lateral force that produces through driving mechanism or the rotation through brush of balance cosily, it can work in the lateral movement of device.Because front carriages is arranged in the forward part of device, so front carriages also allows the turning to property (Lenkbarkeit) and the guiding of whole device.The result is, utilize according to solution of the present invention also can be on the edge of near, promptly for example in the zone of border stone or in the path-segments of narrow curve, work and the difficult section of cleaning optimally itself.This device is suitable for the cleaning face, and especially is fit to being used to clean the slit.
Front carriages can have a plurality of the wheel being used to be stablized, and wherein, especially simple embodiment is equipped with only wheel.Iff is provided with a wheel, then can be reasonably to be, the rotate rotation property (Schwenkbarkeit) of rotation axis of restriction front carriages is to be used for guaranteeing guiding stability by this way.At this, alternatively also can use the wheel of single roll shape.
In addition, can brush be placed motion, wherein, depend on basis to be cleaned in the combination that this motion that lateral movement, rotational motion, waveform are set still is a plurality of motions through driving mechanism.In order to realize the different motion possibility of brush, driving mechanism and same if necessary suitable transmission mechanism are provided or transmit machinery
for use.
First design scheme of the present invention is that the pivot center of front carriages is arranged on the wheel axis of wheel.What can obtain front carriages thus turns to effect (Selbstlenkeffekt) certainly.Thus; The only little motion of front carriages causes the perceptible deflection of whole device, thereby simplifies and improve front carriages and the maneuverability of whole device
thus
Be arranged to, the wheel axis that the pivot center of front carriages is not parallel to wheel stretches, but with the wheel the such angle of wheel axis double team, that is, this angle is about 60 ° to about 120 °.Especially, the wheel axis of wheel is perpendicular to the pivot center orientation of front carriages.Thus, brush can be implemented the motion of reciprocally swinging (hin-und herpendelnd) with respect to front carriages, and it allows simply and very effectively to clean slit, shop face stone and that do not spread stone.Additionally can be arranged to, can be with respect to brush around approximate rotation axis (Schwenkachse) the adjustment front carriages that is parallel to the wheel axis of wheel.In when work, adjust the thrust of brush in the following manner by the operator, that is, the operator pushes the back handle downwards.In order however when working, to realize that also brush is with respect to the rotation property of front carriages around the pivot center of level; The obliquity of pre-adjustment of the pivot center of front carriages can be set, and the thrust (it causes the obliquity of brush) that this obliquity can be through the brush that applied by the operator when work is balance partly or wholly once more.
In order when working, to realize improved stability, can be arranged to, device has a plurality of the wheel, and it has at least two wheel axis that are spaced apart from each other.At this, advantageously, all are taken turns and are arranged in the front carriages place.At this, for example other of front carriages taken turns and can be arranged in the brush next door.Correspondingly, surrounding brush and brush by front carriages with the mode that is similar to framework can be with respect to the pivot axis of front carriages around front carriages, thereby makes brush become possibility with respect to the oscillating motion (pendelnde Bewegung) of front carriages.
When handle is (ergonomisch) operation that realizes human engineering when turning to handle (Lenkergriff) (utilizing two hands guiding to turn to handle).
For the still operation of modifying device further, device can be equipped with two especially independently handles.Thus, utilize this device work (agieren) the operator can, utilize two hands to carry out the suitable guiding aspect human engineering of device.Through such additional handle strengthened equally mentioned turn to effect certainly.The second in command also can be the bow (B ü gelgriff) at the guiding tube place that is arranged in the first in command.At this, but this bow rotation ground or be fixed on the guiding tube place regularly.
Also can find out very favorable solution from following, that is, front carriages is fixed on the device place with adjustable mode on its height placement.Possibility through height adjustment can realize the different position of front carriages with respect to the major part of device.Thus, for example simply mode realizes the heeling condition of brush, and for this reason cost to cross the highland device for modifying be unnecessary.
In order device to be pressed against pending place, basis, weight (Gewichte) can be set be arranged on the front carriages with improved mode.If exist dry and basis that be full of dust, then this weight also can be liquid container, and it for example comprises water and is used for moistening basis.
When brush is contained in the device with height adjustable mode, can obtain other advantage.Thus, brush presses and can change the place, basis, thereby cleaning power can be complementary with the basis that exists.Another advantage is, can regulate the part wearing and tearing that (nachregulieren) is present in the bristle at brush place again, and keeps obtaining cleaning power thus.
Preferably, device according to the present invention has the motor that has slow rotating speed as driving mechanism or have transmission mechanism that the rotating speed that makes brush reduces or a set mechanism of regulating rotating speed.This has such background (Hintergrund), that is, can confirm, the high rotating speed that uses all the time up to now has a plurality of shortcomings equally.Therefore, transverse acceleration and lateral force thus for example appear, must be by this transverse acceleration of user's balance and the lateral force of device, and make the shirtsleeve operation of such device become impossible.In addition, under the situation of not considering its characteristic, fully grind off basis to be cleaned through high rotating speed.This always not rational and being adjusted in the slow running of rotating speed capable of using is avoided.At this, especially by the battery drive motors.
Advantageously, can select the rotation direction of driving mechanism.Alternatively or additionally can be arranged to (oszillierend) drive movement that driving mechanism can be implemented to wave.Advantageously, also can select the drive movement wave by the operator.Thus, can be by the rotation direction of the corresponding adjustment optimization of operator.
When mating brush fully, realize good cleaning result.This can realize in the following manner that promptly, the battery of driving mechanism and/or driving mechanism is arranged on the front carriages.Driving mechanism has big relatively weight, thereby can cancel additional weight or fellow.Can be arranged to, device has the utensil of the automatically reciprocal rotation that is used for front carriages.Thus, automatically produce the oscillating motion of brush, and needn't produce this oscillating motion by the operator.Thus, further simplified operation.
Can be advantageously, device has the reference work direction and is arranged in brush support carriages (St ü tzwagen) afterwards.At this, advantageously, support carriages can around two levels perpendicular to the pivot center rotation of arranging each other.At this advantageously, can the rotation campaign of support carriages be cushioned, thereby support carriages gives device additional stability, and not constrained motion property.Also can be arranged to, be used for the adjustment of working depth and confirm can be in work the time around the motion of the pivot center that is parallel to wheel axis.
Brush in device according to the present invention to be used has been represented design scheme of the present invention; And comprise bristle holder,head (Borstenkopfhalter); The bristle holder,head has a plurality of connection parts that design to be used for by means of fixing separably at least one the bristle head of the connection of suitable power and/or form fit identically; This bristle head has the bristle that is contained in wherein; Wherein, at least one bristle head is being fixed on bristle holder,head place along the guide portion displacement and/or the mode that maybe can be fixed in the different positions that can rotate around the axis.What the such embodiment through brush was at first possible is that the bristle holder,head is equipped with different bristle heads, thereby is present in bristle difference each other on its sanitary characteristics at bristle head place.Thus, provide coupling with the optimization on pending basis.In addition, the rotating or displaceable embodiment of bristle head makes the following possibility that becomes, promptly; Cleaning is carried out in the power consumption that utilization reduces; The bristle head for the operator, alleviated basic cleaning significantly thus, because can be fixed in the optional position at bristle holder,head place.At this, but can imagine the displaceability of single or all bristle heads or such possibility, that is, bristle head or a plurality of bristle head are around rotational or rotation.
A plurality of connection parts of being arranged to identical form have such advantage, that is, the bristle head can be fixed on the different position of bristle holder,head, thus for example can the centre and edge side fixing between alternately.
The design scheme that has the brush of removable brush head has been represented independently creationary idea.The brush of design yet can not have under the situation according to device of the present invention, for example manually use by this way.For this reason, replace driving shaft advantageously to be provided with handle (Stiel) at the brush place.
Another design scheme is following; That is, connection part is slotted hole
hole (Bohrung), plug or bolt in the bristle holder,head.Therefore, according to being proposed in the connection part that is provided with in the bristle holder,head like slotted hole or hole, the corresponding profile of bristle head joins in the connection part.

In order to design the connection (thereby making the change in location of bristle head or the replacing of bristle head become possibility with simple mode) between bristle holder,head and bristle head as far as possible simply, the clip that is connected to of power between bristle holder,head and bristle head and/or form fit connects (Klemmverbindung), snap-on connection (Schnappverbindung) or bolt connection.At this, especially clip is connected with hasp and has represented a kind of quick release system
that is used for the bristle head
According to improved proposal, the connection part that is used for the bristle head can be arranged in the face of on the side on basis to be cleaned and/or be arranged at least one distolateral place of bristle holder,head.At this, especially for crevice cleaning, the bristle head is placed in the distolateral place of bristle holder,head for especially favourable, because can arrange for example more stable or longer bristle at this.In addition, in this zone, can realize the rotation property of bristle head especially simply around axis.
Can directly be fixed on the situation at bristle holder,head place except the bristle head; Favourable solution is; At least one bristle head is can or being contained in the support member along the mode of guiding piece displacement around rotational ground, and this support member has and the power of bristle holder,head and/or being connected of form fit.In this situation, support member also can be fixedly fitted to bristle holder,head place.At this only meaningfully, the bristle head is arranged to and can or can be shifted along guiding piece around the axis rotation.
Improve cleaning power advantageously in order to utilize according to device of the present invention, brush has the bristle head of the bristle that has different materials.In addition, the length of single bristle can differ from one another.Except complete bristle head is equipped with a kind of possibility of bristle of material, within the bristle head, also can be arranged to, the bristle with material different and/or length is set.This measure makes the optimization of cleaning power become possibility.
In addition, very reasonable scheme of the present invention is that bristle has obliquity.This obliquity can represent, bristle is oriented to and cleans direction (Kehrrichtung) and tilt on the contrary or identically.Though the power consumption that is used to clean during the inclination of the bristle of sensing cleaning direction is bigger, yet can obtain extraordinary effect thus, especially when crevice cleaning.In contrast, utilize bristle head and cleaning to tilt, the processing of good (schonen) on basis is possible in the opposite directionly.
A kind of embodiment preferred is that the bristle holder,head has the length bigger than width and extends, or in the simplest situation, designs conglobate dish.The various arrangement that is used for the connection part of bristle head both can be arranged on the main body place of extending on the length also can be arranged on circular Pan Chu, thus being designed to very flexibly owing to this solution brush.
Especially, when bristle is made up of stone material, can occur, when cleaning, damage object, like flowerpot (Blumentopf), stone edging (Steineinfassung) or stake (Pfahl) through bristle.In order to prevent this situation and make the protection of bristle holder,head become possibility in addition that very favorable improvement project of the present invention is that the bristle holder,head is contained in the outer cover (Haube) with protected mode.In addition; Utilize this solution, also realized the protection of the bullet of the bristle that unclamps
from (Wegspringen).
Find out another advantage from following, that is, the bristle head is contained in the outer cover with height adjustable mode, and for example can realize thus, and bristle only stretches out several millimeters under outer cover.Adjustable in height can be through simple measure realization, for example screw thread or suitable machinery.Through such embodiment; Near the edge cleaning is possible; Particularly same cleaning in such zone is possible; That is, do not damaging under near the situation of the object the face of shop stone or the contiguous kind of plant (Bepflanzung), utilizing traditional device to arrive should the zone.
