Description

Holder for covers of mops

Technical area

The present invention relates to a holder for covers of mops.

Technical task

In the cleaning of large flat surfaces, such as linoleum floors, but also tiled surfaces as they are available in sanitary facilities or other spaces in which high hygiene value is placed, mops are often used. A mop is a cleaning device that has a pivotally mounted bottom plate attached to a long handle.

At this bottom plate (holder), seen from the handle on the opposite side, a mop cover is provided, which can be moved over the ground. This is stretched by the bottom plate and thus lies substantially taut on this. As a result, the shape of the mop cover is predetermined by the bottom plate and this in the

Is essentially flat, also has a mop cover in the

Essentially flat surface. This can be wiped over the surface to be cleaned, which makes large

Floor surfaces can clean well. This is particularly supported by the fact that the mop cover is often provided with fringes, which are normally up to about 10 cm long. The mop cover can also be soaked with water, which may also contain a cleaning agent, whereby the cleaning effect is enhanced.

However, as is clear from the above, is a

Problem that the mop cover picks up dirt during use and thus after some time its cleaning effect

loses. Another problem is the wear of the Mop cover after prolonged use. As this, however, on the mop cover alone, but not on the bottom plate

If it is correct, it would not make sense to replace the mop cover together with the bottom plate. Therefore, it is provided according to the prior art, to make the bottom plate and the mop cover so that the mop cover is interchangeable.

This is achieved according to the prior art by providing the bottom plate substantially in the form of an elongated rectangle, which can be folded with respect to its longitudinal direction. As a result, the longitudinal ends come close together. In such a

Condition, a suitably sized mop cover, which has pockets at its longitudinal ends, are pushed over the longitudinal ends of the folded bottom plate. When this bottom plate is now transferred from the folded state to the flat state, the mop cover is pulled straight through the pockets and through the bottom plate and also held by them, d. H. he can not slip off the bottom plate. At the same time, however, by refolding the bottom plate, it is easy to remove the cover from it.

A problem, which occurs here, however, is that one wants to prevent the one hand, that the bottom plate of the mop is folded unintentionally, as a result, the mop cover could fall off in use. On the other hand, however, one also wants to have a mop in which the mop cover is easily replaceable when needed and which, especially in

Considering the high time pressure u.a. at cleaning companies, quickly changeable.

Presentation of the invention

The present invention aims to provide a holder for a mop which is designed so that the mop cover is easily replaceable. A solution to this problem results from the holder for holding mop covers for detergent according to claim 1. Preferred embodiments are in the dependent

Claims 2 to 11 described.

According to claim 1, a holder for holding mop covers for cleaning agent has a central part, two lockable

Folding wings, which are pivotally mounted on the central part, a locking device, which can lock the two folding wings in a pivoting position relative to the central part, and a device to the locking of the

locked folding wing with respect to the central part to solve so that the folding wings can be pivoted. In other words, the bottom plate of the mop is divided into three parts. On the one hand, there is a middle section, which lies between the two folding wings. The folding wings can be pivoted about this central part, so that they can be pivoted between a first configuration in which the two folding wings and the central part together form a plane on its underside (planar configuration), and a second configuration in which the two folding wings together form a substantially U-shaped shape with the middle part. In the second configuration, a mop cover can be mounted on the holder. This mop cover is held by existing at its ends pockets in the first configuration by the holder and thus can no longer slip down from this unintentionally. The pivotable mounting of the folding wings with respect to. The middle part can for

Example by an axle bearing, but it can also be done by the folding wings with the

Middle part by means of a flexible connector

are connected.

The locking device ensures that the two

Folding wings in the first configuration, ie a position can be held, in which the holder is a flat Bottom plate forms and does not unintentionally "folds".

A feature of the present invention is that the

Locking device is biased to the state in which the two folding wings are locked. As a result, the holder locks when unlocked when moving the two folding wings toward a state in which the lower

Surfaces of the two folding wings lie substantially in a plane, the folding wings automatically the

Locking device. In other words, this means that a user does not have a separate action for locking the

Folding wing must make if you want to convert these from the U-shaped configuration in the planar configuration. It is sufficient to only pivot the folding wings, which can be done, for example, by pressing them against a floor to be cleaned. As a result, they spread outwards, which, as described in the claim, leads to an automatic lock. Since this does not require a separate locking step in addition to the spreading, this leads to the holder being easily provided with a new mop cover.

According to a preferred embodiment, the

Locking device for at least one of the folding wings, preferably for both, a stop on the folding wing and with respect to the central part movably provided part of the system, which has at least one partial investment stop. Here are the attack on the folding wing and the

Annex stop with locking of the folding leaf

engaged with each other while loosening the

Locking by moving the system part disengaged. In other words, a system part is provided, to which the respective folding wings / the folding wings at

Can trigger detent. These are securely locked by the resulting contact with the middle part and blocked, which is why the bottom plate of the pug at

Use not or only slightly deformed.

It has also been found to be advantageous that the means for releasing the locking of the folding wings with respect to the central part comprises a manually operable push-button. If you press this, this will lead to

sufficiently strong operation, to solve the lock. For this to be possible, the push button is coupled to the system part. The push button leads to a

Movement of the part of the system, which in turn solves the lock on displacement by a predetermined path. In other words, there is a push button on the holder, which enables, so to speak "push of a button" releasing the lock.Since this is coupled to the plant part, this is a slight solution of the lock allows so you can even after prolonged work on the mop Remove mop cover easily and easily, since such a

Pushbutton even after prolonged work and appropriate

Exhaustion of the muscles works well.

In this context, it is an advantage that you can do that

Plant part and the push button integrally formed, d. H. that these consist of a single component. This allows a simple design of the mop, it is now no complicated coupling between the system part and push button needed.

In the previously described sub-investment stop, it has proved to be advantageous if this is directed downward, especially if this is directed obliquely downwards. Here, the direction "down" refers to the direction that extends perpendicularly from the side in the holder, in the locked state by the

Middle part and the two folding wings a level is formed. Others say it is the side that, at

Use, a stalk and possibly with the holder connected handle is opposite. In this respect, it is the side of the holder, which rests on the surface to be cleaned in normal use. Furthermore, the

Stop on the folding wing preferably aligned such that it rests flat in the locked state of the flap on the abutment part stop.

In other words, this means that the attachment part stop at least partially points downwards (even if he

preferably inclined). Due to the fact that the stop on the folding wing preferably lies flat against the abutment part stop in the locked state, there is good contact between these two stops. In this respect, a good lock is ensured. By aligning the

Anlageteilanschlags down, preferably obliquely down an unwanted pivoting of the folding wings can be well and reliably prevented.

Furthermore, it is preferred that the contact part is movable substantially parallel to the pivot axis of the folding leaf. In particular, it is preferred in this case that the contact part is movable only substantially parallel to the pivot axis of the folding wing, d. H. that you can not move this or only slightly in another direction. An advantage of this feature taken by itself is that it ensures a good and easy demolding of the plant part. In particular, a cleaning specialist will find it easier after a long work, a part of the system in

Entformen substantially parallel to the pivot axis of the folding wings than would be possible, for example, along a direction of the stem.

In a combination with the features of claim 2, this would also have the advantage that an unwanted except

Engagement of the attacks is prevented, which would be given in a mobility in other directions under certain circumstances. So could a mobility perpendicular to the Swing axles cause the system part is pressed up or to the side when exerting pressure on the folding wings. However, this could lead to the corresponding parts disengaged, which can lead to slipping and falling of the mop cover.

In addition, it is advantageous if the pivot axes of all folding wings are substantially parallel to each other.

This allows you to easily fold the holder and thereby remove the mop cover.

In the aforementioned embodiments, it is also of

Advantage that there is another device that the

Pivoting range of at least one or preferably all lockable folding wing in the unlocked state limits. As a result, the Verschwenkungsbereich is limited so that the folding wings must include a minimum angle with each other. This means that they include an angle of at least 10 °, preferably 20 °, more preferably 30 ° with the direction downwards in the unlocked state. This is when using

Advantage. In other words, in use, it is particularly advantageous if the two folding wings make an angle of approximately 60 °, i. in about 55 ° to 65 °, symmetrical to each other with the direction down. This prevents the folding wings from completely falling down after releasing the lock. This would make it more difficult for the holder to be fitted with a mop cover. In that the folding wings with the different angles to the outside

spread are easy to convert these in the flat state of the bottom and at the same time span the mop cover by the holder, with the folding wings down, just against the surface to be cleaned, on which the mop cover is pressed. This brings, as can be seen from the above, advantages in terms of ease of use. Said Verschwenkungsbereich-restricting means advantageously has a central part stop, which is provided stationary with respect to the central part. This means that there is a further stop at the central part, which can engage the associated folding wing, in particular preferably the already defined stop of the folding wing, in the unlocked state. This is in a simple way, but at the same time reliable, the

Swiveling range restricted. The simple design of this device can reduce production costs.

In the said preferred embodiments, it is also advantageous that the automatic locking takes place in the state in which the lower surfaces of the two lockable folding wings lie substantially in one plane. This will increase the usability of the pug in the

locked state ensured.

Furthermore, it is preferred that a handle is provided on the central part, which is pivotable about two axes with respect to the central part and preferably in a rotational position about an axis. As a result, you can easily use the holder, for example, under furniture, especially if you attach a handle to the handle.

Detailed description of the figures

FIG. 1 illustrates an exploded view of the holder 10 according to the present invention. The assembled holder 10 can be seen in FIG.

This holder 10 has a handle 28 which is rotatably mounted on an intermediate part 34. This rotatable or pivotable mounting can with respect to a pivot axis by means of a locking device 30 in a

Pivoting position to be locked. At the intermediate part 34, the central part 12 is provided by means of a pivot axis 32. At this middle part 12 are by means of two

Axles 22 two folding wings 14 attached. At the middle part 12, a push button 20 is further provided movable, which is partially received in a groove 13 of the central part 12 on the side of the handle 28. The handle 28

opposite surfaces of the folding wings 14 and

Middle part 12 form the surface which abuts when using the holder in a mop, together with the mop cover attached thereto to the surface to be cleaned.

The push button 20 itself serves to actuate or to solve the locking device, which will be described in detail later. It is slidably received in the groove 13, but in addition it is received in a hollow cap 21 which is formed on the central part 12 on the side of the groove 13. In this respect he will be along a

Supplement taken from the central part 12, wherein he however, protrudes from the central part 12. In this respect he is easily operated from the outside. The details will be later

to be discribed.

The two folding wings 14 are flat, plate-like elements whose basic shape is substantially rectangular. On a narrow side of the rectangles, which lies outside when holding a mop cover, they have a substantially smooth edge. On the opposite side provided with through holes projections are provided which can be connected to the central part 12. The through holes are aligned so that in each of the

Projections a through hole is provided which extends parallel to the narrow side of the flap and which has the same diameter for each projection. The through holes are aligned with each other, so that through these through holes a single pivot axis 22nd

can be passed. These holes become

Connection of the respective folding wing 14 used with the central part 12.

Among the mentioned projections of the folding wings 14, the projection 18a deserves special mention since this in the

Locking the folding wing 14 with respect to the central part 12 plays a role. This projection 18a is at such a position of the projected narrow side of the

Folding wing 14 provided that it can penetrate into a later-mentioned Durchläse 19 of the middle part. At its longitudinal end, it has a bevelled

Surface 18 which extends in an assembled holder 10 obliquely downwards.

The middle part 12 is a body that can be described essentially as a two-part. On the one hand, there is a flat, rectangular part, on whose long sides to the narrow-side projections and

Recesses of the folding wings 14 matching recesses and Projections are provided. These projections are with

Through holes provided, which fit to the through holes in the folding wings 14, so rod-like

Pivot axes 22 can be used by this, whereby the folding wings 14 with the middle part 12th

be connected pivotally. On the central part 12, however, there is also a hollow attachment 21, the one to a

Narrow side of the central part 12 is open toward, but is substantially closed at the other sides. This

Attachment 21 is formed integrally with the lower part and has substantially the shape of a cuboid with

rounded corners.

On the side of the outlet 21, which is open, a groove 13 is formed in the flat, rectangular part of the middle part 12, which in cross section has a trapezoidal shape, which tapers downwards. This groove 13 extends along the longitudinal direction of the flat, rectangular portion of the central portion 12 of the cap 21 to the opening of the attachment 21 opposite end of the central portion 12th

Parallel to the narrow side, d. H. perpendicular to the

Longitudinal direction of the central part 12, two bores 33 are further provided in the attachment 21, which are parallel to the

Extend underside of the middle part 12. These pass through the walls of the cavity defined by the attachment 21 in alignment.

In this cavity is in the assembled state of

Push button 20 used. This push button 20 has the shape of a hollow body which is open on one side. One could also call this form a hollow cuboid, with one side open. The push button 20 is inserted with this open side opposite the closed side of the attachment 21 into the cavity of the attachment 21. The push button 20 also has on the two sides, which face the holes 33 after insertion into the attachment 21, each holes 37, which are aligned with the holes 33. However, these holes 37 are elongated. The longitudinal direction of these elongated holes 37 is, after insertion of the push button 20, parallel to the longitudinal direction of the central part 12. Thus, one can use through the holes 33 and 37, an axis 32, without preventing the push button 20, with respect to the attachment 21 along the longitudinal direction of the central portion 12 to be moved.

Between the push button 20 and the closed wall of the attachment 21, a spring 36 is provided, which serves to push the button 20 to the opening of the attachment 21

to bias, d. H. this spring pushes the push button 20 to the outside. The spring is, e.g. by corresponding projections in the push button 20 and top 21, held so that they can not slip with respect to these two components. As will be apparent from the later description, the tension of the spring 36 is important in that it achieves the automatic locking previously described.

At the time of insertion into the article 21 lower side of the push button 20 is a system part 16, which takes the form of a downwardly tapered trapezoid in

Cross-section perpendicular to the longitudinal direction of the central part 12 has. This trapezoid fits into the groove 13, d. H. You can use this projection in the groove 13 and move in this groove 13 along the longitudinal direction of the central part 12. Within the middle part 12 there are in

the area in which the attachment 21 is located, a passage 19, in the assembled holder 10, a correspondingly dimensioned projection 18 a of the folding wings is inserted. This passage 19 is dimensioned such that the projection 18a can contact the contact part 16, in the case of a corresponding longitudinal position of the pushbutton 20. Ie. this passage 19 allows, in addition to the already mentioned opening of the Essay 21, another access to the interior of the

Attachment 21. The passageway 19 also divides the flat rectangular portion of the central portion 12 into two parts, substantially parallel to the narrow sides of the flat rectangular portion. These two parts are held together by the attachment 21.

At the top of essay 21, d. H. on the side opposite the bottom of the holder 10, is an intermediate part 34th

placed. This intermediate part 34 has two arms 35, each having a bore. By means of this bore they can be connected to the attachment 21 and the push button 20. More specifically, the axle 32 is inserted through the bore of one of the arms 35 of the intermediate member 34. It then passes through the hole 33 of the cap 21 and through one of the holes 37 of the push button 20 therethrough. Then it passes through the other hole 37 of the push button 20 and through the associated hole 33 of the cap 21 therethrough to finally into the other hole of the other arm 35 of the

Intermediate part 34 to penetrate. This will be the

Intermediate part 34, the middle part 12 and the push button 20 connected. In particular, this can be prevented that the push button 20 is pushed out of the article 21 by the force of the spring 36, since the boundary of the hole 37 abuts the axis 32 and thus prevents forcing out by the clamping force of the spring 36. In this respect, the axis 32 not only has the task of providing a pivotable connection between the handle 28 and the holder 10, but also serves to slipping out of the

Prevent push button 20.

In the intermediate part 34 is another hole 34 a, via which the handle 28 is mounted pivotably with respect to the intermediate part 34.

In order to better understand the locking mechanism, we will discuss below in detail on Figure 3. In this Figures are no longer all the reference numerals used in Figures 1 and 2 introduced to an understanding not to

difficult.

In FIG. 3, a partial sectional view, enlarged relative to FIG. 2, of the holder 10 is locked in place

State shown. In the locked state form the lower sides of the folding wings 14 and the central part 12 in

Essentially a level. By the tension of the spring 36, the push button 20 is as far as possible to the outside

crowded, d. H. until the opening of the essay 21st

opposite edges of its holes 37 rests against the axis 32 and thereby further movement of the

Push button 20 prevents. In such a state, the abutment member 16 is located within the passage 19. Thereby an interaction with the projections 18 a of the

Folding wing 14 possible.

Concretely, this means that a surface (stop) 18 of the folding wing 14 with the side surfaces (abutment part stop) 17 of the abutment member 16 is engaged. In other words, the stops 18 of the folding wing 14 and the trapezoidal leg surfaces of the abutment part 16 lie flat against one another, so that a pivoting of the folding wings 14 downwards is prevented. In this state, however, it is possible, the push button 20 by manual operation in the essay 21st

inside push. As a result, the contact part 17 is moved out of the passage 19. As a result, however, an engagement of the stops 18 and system part stops 17 is no longer possible. This has the consequence that the lock is released, whereby the folding wings 14 can be pivoted.

However, this pivoting is limited by the upper part of the passage 26, which forms the middle part stops 26. Against these are the surfaces 18, when the maximum pivoting of the folding wings 14 is achieved and thus prevent further pivoting. In this respect, form the system part stops 17 of the system part 16 together with the surfaces 18 of the projections 18 a the

Locking device. The surfaces 17 and 18a are, in the locked state, flat against each other. Because the

Surfaces 17 and accordingly the surfaces 18 are directed in the locked state obliquely downwards, the projections 18 a can not be pivoted upwards. Furthermore, pivoting of the projections 18a downwards is prevented by a similar arrangement. This has the consequence that in the folding wings 14 of that part which extends from the pivot axes 22 to the outside, can not be moved down in the locked state. In this respect, a pivoting of the folding wings 14 in this state

prevented, the holder is thus, as regards the positioning of the folding wings 14 with respect to the central part 12,

locked. Now, as is the case, ensuring that the lower surfaces of the folding wings 14 and the middle part 12 form a plane, the holder can thus be used well for holding mop covers and thus for cleaning surfaces without the holder 10 significantly deformed.

However, pressing the push-button 20 sufficiently deeply leads to the state shown in FIG. 4, which is also shown in FIGS. 5 and 6. Here was the

Push button 20 pressed so strong that the contact part 16 was completely removed from the aperture 19 and thus releases it. As a result, no more investment between

Surfaces 18 and 17 is possible, there is now no more locking, d. H. the projections 18a can also be pivoted upwards. The lock is thus solved. In a typical use of the holder 10 in a mop, this is because the length of the folding wings 14 outside of the pivot axes 22 is significantly greater than the length

between them, due to gravity cause the folding wings 14 to fold down independently, as they now no longer be prevented by the lock. In this respect, fold the folding wings 14 together, and a

Existing mop cover can be easily removed, provided that it does not already detach itself from the holder automatically.

At the same time pushing out of the push button 20 is prevented by the spring 36, since the projections 18 now abut against the opening of the attachment 21 opposite surface on a corresponding surface of the abutment member 16 (see Figure 5). This system is blocking

Pushing the push button 20 by the spring 36. In this respect, the push button 20 remains in its depressed state, which is also clear from Figure 6 (in particular in comparison to Figure 2). However, if you return both folding wings 14 back into the locked state, the z. As shown in Figure 2, this procedure is solved. The spring 36 then urges the push button 20 out due to its resilience and performs independently, d. H. without external action by a user, to a locking of the folding wings 14 with respect to the central part 12. A slight locking of the holder 10 is ensured.
