Description
Manually-operated implement suitabIe Eor cleaning flat surfaces, especially glass sheets The invention relates to a hand implement suitable for cleaning flat surfaces, more particularly sheets of glass.
A glass~cleaning implement is known from German utility model 1 85 32 656. The implement has a body for holding a sponge and a handle. Spring-loaded balls and ratchet knurls permit a pair of joints to be locked in a series of positions assumed by a handle relative to the body.
Unintended shifting of the handle may occur if increased lateral pressure is applied to the handle, since ;~ l~the spring-loaded ball is, in such instances, forced~out ; of~the ratchet knurls, resulting in limited usefulness of the conventional handle lock.
In addition, adjustment of such handle by the user is awkward, as both~hands must be used for this procedure.
~ The object~of the present invention is to improve and simplify the locking behaviour of the handle of the hand implement of the design mentioned~above, to permit the ~ ;
us~e~r of such an~implement to be able to adjust the position of the~handle;with one hand and to permit an automatic 20~ movement of the joints into the locked position, through use of~ a~suitably designed and arranged resetting member.

:129~3~5 According to the invention there is provided a hand implement suitable for cleaning flat surfaces, said hand implement comprising a holder formed as a flat casing, said holder being capable of holding a sponge and a wiper !j blade; a handle provided on said casing and having two superposed joints, said handle being capable of being tilted and laterally adjusted about axes that are oriented perpendicular and parallel to said holder both of said joints being capable of being brought into the locking position and held therein by means of a spring.
The implement preferably has a holder in the shape of a flat casing and capable of holding a sponge, as well as a wiping edge arranged at a distance from such sponge.
Both the sponge and the wiping edge are replaceable. The implement also ha's a handle featuring two superposed joints which are arranged about a vertical axis and about an axis oriented parallel to the holder, such that the handle is able to tilt and move laterally relative to the holder.
The implement of the invention makes use of an articulated head that permits the handle to be moved laterally and tilted, such head having an exceptionally simple and effective design, and being capable of working in concert with a locking sleeve serving as a rotating joint~and with a locking extension serving as a swivel joint, whereby both joints can be brought automatically into, and held in, a locked position by means of a common ; spring.
Tooth- or pin-shaped protrusions arranged on the 30 ~locking sleeve and apertures arranged in the holder may act as a locking means. Alternatively, the locking means may be locking casing and holder meshing teeth, which also produce a snug and secure fit.
The spring arranged around the axis of the turning : :
-- 3 ~
joint acts as a pressure spring by holding both joints securely in each of their locking positions and at the same time causes the joints to move automatically into the locking positions.
The handle is capable of being adjusted with one hand, in that as the user grasps the handle and exerts a pressure upon such handle against the force of the spring, the handle is able to move relative to the holder into the unlocked position, and is thus movable into any desired pOsition.
When the holder is released, the spring automatically and simultaneously returns both joints to the locked position.
A spring-actuated pusher permits, due to its design, the handle to be adjusted with one hand while being gripped. The pusher is slid against the force of the spring into the release position, allowing movement of the handle in both directions. After being released, the pusher is quickly and automatically returned by the spring into the locked position. The pusher is securely held by the spring, such that unintended displacement of the pusher is prevented.
The design of the pusher and spring, while being simple and cost-effective, has served to improve and simplify the handling of the cleaning implement.
Preferred embodiments are described in detail below with reference to the accompanying drawings, in which:

; Identified by numeral 1 in Fig. 1 is a flat casing of a holder belonging to a hand implement suitable for cleaning flat surfaces, and more particularly, sheets of ; glass. The holder is holding a sponge 2 (Fig. 2) and, 20 spaced from sponge 2, is a replaceable or permanent wiper blade 3.
A handle is attached to the holder, the handle having two superposed joints. The handle is capable of being tilted and shifted laterally in relation to axes 5, 6 2S oriented perpendicular and parallel to the holder 1. Two joints (SG, DG) are brought into, and held in, a locked position by means of a spiral spring 7. The rotating joint (DG)~comprises a locking sleeve 8, and the swivel ;joint (SG) comprises an extension of the locking 30 arrangement 9. ~peing 7 is arranged about a rotating joint shaft 5.
Rotating joint shaft 5 is formed by a pin fixed in a suitable position inside a bearing casing 10 of holder 1.
Around such pin, spring 7 is arranged so as to be 35 supported at one end by an abutment 11, 12 and at the :;
~: :
33'~
other end by an abutment 13, 14 of the lockinq sleeve 8.
Locking extension 9 forms part of handle 4 and has a semicircular shape on the edge of which are featured a number of evenly distributed teeth 15. Acting as locking elements, teeth 15 cooperate with locking grooves 16 acting as mating-locking elements that are disposed upon a neck 17 or a casing 18 of pin 5, whereby the neck 17 or casing 18 forms part of pin 5 and protrudes through locking casing 8.
The gear-shaped locking extension 9 of handle 4 is positioned between a fork element 19 of locking lining 8, and is supported by horizontal shaft 6 in fork element 19 so as to be permitted to swivel. Locking extension 9 is connected by fork element 19 to locking sleeve 8.
Handle 4 is, together with its locking extension 9 and locking lining 8, capable of being slid in the longitudinal direction of pin 5 against spring 7. Handle 4 is also able to turn together with locking lining 8 about pin 5 situated within bearing sleeve 10.
The handle is locked into its angular swivel positions by means of cooperating locking elements 15, 16 and into its rotated positions by means of cooperation between locking elements 20, 21 that form part of locking sleeve 8 and mating locking elements 20, 21 set in holder 1, whereby 25 spring 7 serves to move the handle into both locked positions.
In the embodiments of ~igs. 1 to 3, locking slee~ve 8 has;the shape of a pot, and the upper pot floor 8a is supported upon abutment 11 when the implement is in the locked position.
Locked into locking sleeve 8 at a distance from the lower~open end of the lining is an abutment plate 13 which, wlth protruslons 13a, fits into recesses 24 of locking lining 8 and surrounds pin 5 by means of a centred 3'; opening 13b. Spring 7 is supported at one end by abutment ;: : :
: ~
3 ~33 ~
plate 13, its other end pressing against a collar-shaped ab~tment 11 of pin 5.
Locking protrusions 20 that form part of the open frontal end of the lining are oriented in the direction of S the lining axis and fit at various angular positions into locking recesses 22 of a locking plate 25 that is permanently installed in holder 1.
Whereas locking protrusions 20 are formed by teeth or pins, locking recesses 22 are holes. Both types of locking elements 20, 22 are disposed at equal intervals in an arc around the circumference.
Locking plate 25 fits over the lower frontal end of bearing casing 10 and snap ring groove neck 5a of pin 5 passes through a keyhole-shaped recess 26 in the plate in such a way that locking plate 25 is held in position.
An alternative design of the articulated head of the hand implement is shown in Figs. ~ to 7. This embodiment corresponds in principle and in function to the articulated head shown in Figs. 1 to 3. Hence, locking lining 8 is also pot-shaped and possesses a rotatable inner toothing 21 underneath its bottom-situated pot floor 14, which also serves as the abutment for spring 7. Embodied as a toothed wheel rim, toothing 21 serves as a locking element.
Pot-shaped bearing casing 10 of holder 1 possesses on its pot floor lOa a set of external teeth 23. Being embodied in an outer toothed wheel rim, those teeth act as a set of locking elements that cooperate with inner toothed wheel rim 21 of locking sleeve 8. In each position assumed by rotated handle 4, the teeth 21, 23 mesh with each other.
Pin 5 penetrates pot floor lOa or bearing casing 10, and is held in place inside bearing casing 10, by a securing ring 27 that fits around annular grooved neck 5a and rests against the bottom of pot floor lOa.
~33~5 Attached to the upper end of pin 5 is a pot-shaped lining 18 that acts as the abutment 12 for spring 7 and features in its external surface locking grooves 16.
Spring 7, preferably a spiral spring, urges the 5 members apart.
When the i~plement is in the locked position, spring 7 presses (compare Figs. 1 and 4), against both abutments 11, 12, and 13, 14. Handle 4 together with its locking extension 9 fits into locking grooves 16, and locking lining 18 together with its locking elements 20, 21 meshes with locking means 22, 23 whereby the handle can be locked into its swivel and turning positions.
In order to be adjusted, handle 4 is slid in the longitudinal direction of pin 5 against the force of spring 7. As a result, spring 7 is compressed between abutments 11 and 13 or 12 and 14, and locking protrusions 15 of extension 9 slide out of locking grooves 16 of stationary pin 5. Locking protrusions 20 or 21 slide simultaneously out of locking protrusions 22 or 23 by virtue of the corresponding movement of locking lining 3 with handle 4 in the longitudinal direction of the pin.
Handle 4 is thus once moee able to tilt about its slewing axis 6 and simultaneously rotate with its lining 8 inside bearing casing 10 into any desired position about axis 5.
Spring 7 then pulls both joints (SG, DG) once again into the locked position in which locking protrusions 15 fit into locking grooves 16 and locking protrusions 20, 21 fit into locking protrusions 22, 23.
The handle can be adjusted with one hand. With the hand grasping handle 4, the fingers press upon holder 1 against the force of spring 7, thus permitting handle 4 to tiIt and rotate in relation to holder 1.
Release of holder 1 causes spring 7 to push both joints (SG, DG) automatically into the locklng positions.
h~3~5 In accordance with a further embodiment shown in Fig.
8, the rotating joint (DG) can have in the zone of its upper edge facing the swivel joint (SG) the locking means, whereby teeth 28 are arranged on the rotating circum~erence of locking lining 8 and locking grooves 29 are arranged in bearing casing 10.
Holder 1, handle 4 and the locking lining 8 with its fork section are all formed from a single piece of synthetic material.
Pin 5, abutment collar 11 and neck 17 or lining 18 can, like locking plate 25 or securing ring 27, be produced from either synthetic material or metal;
abutment plate 13 can consist either of metal or a synthetic material.
Handle 4 of the hand implement shown in Figs. 9 and 10 exhibits a semicircular extension 9 comprising locking grooves 9a. The extension 9, supported by joint section 30 that is borne in bearing casing 10 and capable of turning about axis 5, is itself capable of slewing about the axis 6 that is oriented at an angle to the axis 5 of joint section 30. A lock-and-release pusher 31, capable of sliding back and forth parallel to axis 6, is arranged between axis 6 and the opposing edge of bearing casing 10, penetrates joint section 30 and features locking teeth 32, 33. Locking teeth 32 conspire with locking grooves 9a of extension 9, and locking teeth 33 conspire with locking grooves 34 arranged in bearing casing 10.
Locking grooves 34 are evenly distributed along the circumference of bearing casing 10, and the case-shaped joint section 30 exhibits guide grooves 35 in which pusher 31 is borne.
The lower case-shaped partial zone of joint section 30 is arrested at the underside of bearing casing 10 by means of a stopping lip 36.
Semicircular extension 9 similarly exhibits a plurality ~33~5 of grooves evenly distributed in an arc.
Lock-and-release pusher 31 is actuated by spring 7, which is capable of moving such pusher into and holding it in the locking position.
Forming part of lock-and-release pushec 31 is a guide 37 embodied as an abutment sleeve, into which one longitudinal end zone of spring 7 extends; the other longitudinal end rests against joint section 30.
Guide 37 extends between locking teeth 33 which ate capable of locking handle 4 during axial rotation relative to holder 1, and are oriented parallel to the longitudinal direction of the pusher.
Casing-shaped guide 37 simultaneously forms an abutment which serves to limit sliding motion of pusher 31, in that the guide 37 comes to rest against the inside of joint section 30 in the locked position.
Lock-and-release sliding element 30 is embodied as a cylindrical pin of circular cross section having opposed locking teeth 32, 33 for the rotating and slewing joints (DG, SG). Spring 7 is preferably embodied as a pressure spring (helical spring); such spring can, however, be embodied as a tension spring andj accordingly, be attached by both of its ends to an abutment of pusher 31 and to joint section 30.
In order to adjust the articulated head (rotating joint DG and swivel joint SG) that comprises extension 9, pusher 31 and joint section 30, as well as bearing casing 10, sliding element 31 is slid by hand against the force of the spring. The locking teeth 32, 33 can slide at the same time out of grooves 9a, 34, whereupon handle 4 together with its extension 9 can be slewed about axis 6, and with its joint section 30 rotated ins-de bearing ~ ~casing 10 about the axis 5 that is perpendicular the axis ; ~ 6. The stepwise angular adjustment of handle 4 is thus ~ ~ ~ 35 enabled in both directions relative to holder 1.
~ pon beinq released, sliding element 31, is automatically slid by spring 7 back into the locking position, the locking teeth 32, 33 fitting into grooves 9a, 34, and locking the device into the adjusted handle S setting.

; Identified by numeral 1 in Fig. 1 is a flat casing of a holder belonging to a hand implement suitable for cleaning flat surfaces, and more particularly, sheets of ; glass. The holder is holding a sponge 2 (Fig. 2) and, 20 spaced from sponge 2, is a replaceable or permanent wiper blade 3.
A handle is attached to the holder, the handle having two superposed joints. The handle is capable of being tilted and shifted laterally in relation to axes 5, 6 2S oriented perpendicular and parallel to the holder 1. Two joints (SG, DG) are brought into, and held in, a locked position by means of a spiral spring 7. The rotating joint (DG)~comprises a locking sleeve 8, and the swivel ;joint (SG) comprises an extension of the locking 30 arrangement 9. ~peing 7 is arranged about a rotating joint shaft 5.
Rotating joint shaft 5 is formed by a pin fixed in a suitable position inside a bearing casing 10 of holder 1.
Around such pin, spring 7 is arranged so as to be 35 supported at one end by an abutment 11, 12 and at the :;
~: :

other end by an abutment 13, 14 of the lockinq sleeve 8.
Locking extension 9 forms part of handle 4 and has a semicircular shape on the edge of which are featured a number of evenly distributed teeth 15. Acting as locking elements, teeth 15 cooperate with locking grooves 16 acting as mating-locking elements that are disposed upon a neck 17 or a casing 18 of pin 5, whereby the neck 17 or casing 18 forms part of pin 5 and protrudes through locking casing 8.
The gear-shaped locking extension 9 of handle 4 is positioned between a fork element 19 of locking lining 8, and is supported by horizontal shaft 6 in fork element 19 so as to be permitted to swivel. Locking extension 9 is connected by fork element 19 to locking sleeve 8.
Handle 4 is, together with its locking extension 9 and locking lining 8, capable of being slid in the longitudinal direction of pin 5 against spring 7. Handle 4 is also able to turn together with locking lining 8 about pin 5 situated within bearing sleeve 10.
The handle is locked into its angular swivel positions by means of cooperating locking elements 15, 16 and into its rotated positions by means of cooperation between locking elements 20, 21 that form part of locking sleeve 8 and mating locking elements 20, 21 set in holder 1, whereby 25 spring 7 serves to move the handle into both locked positions.
In the embodiments of ~igs. 1 to 3, locking slee~ve 8 has;the shape of a pot, and the upper pot floor 8a is supported upon abutment 11 when the implement is in the locked position.
Locked into locking sleeve 8 at a distance from the lower~open end of the lining is an abutment plate 13 which, wlth protruslons 13a, fits into recesses 24 of locking lining 8 and surrounds pin 5 by means of a centred 3'; opening 13b. Spring 7 is supported at one end by abutment ;: : :

Locking protrusions 20 that form part of the open frontal end of the lining are oriented in the direction of S the lining axis and fit at various angular positions into locking recesses 22 of a locking plate 25 that is permanently installed in holder 1.
Whereas locking protrusions 20 are formed by teeth or pins, locking recesses 22 are holes. Both types of locking elements 20, 22 are disposed at equal intervals in an arc around the circumference.
Locking plate 25 fits over the lower frontal end of bearing casing 10 and snap ring groove neck 5a of pin 5 passes through a keyhole-shaped recess 26 in the plate in such a way that locking plate 25 is held in position.
An alternative design of the articulated head of the hand implement is shown in Figs. ~ to 7. This embodiment corresponds in principle and in function to the articulated head shown in Figs. 1 to 3. Hence, locking lining 8 is also pot-shaped and possesses a rotatable inner toothing 21 underneath its bottom-situated pot floor 14, which also serves as the abutment for spring 7. Embodied as a toothed wheel rim, toothing 21 serves as a locking element.
Pot-shaped bearing casing 10 of holder 1 possesses on its pot floor lOa a set of external teeth 23. Being embodied in an outer toothed wheel rim, those teeth act as a set of locking elements that cooperate with inner toothed wheel rim 21 of locking sleeve 8. In each position assumed by rotated handle 4, the teeth 21, 23 mesh with each other.
Pin 5 penetrates pot floor lOa or bearing casing 10, and is held in place inside bearing casing 10, by a securing ring 27 that fits around annular grooved neck 5a and rests against the bottom of pot floor lOa.
~33~5 Attached to the upper end of pin 5 is a pot-shaped lining 18 that acts as the abutment 12 for spring 7 and features in its external surface locking grooves 16.
Spring 7, preferably a spiral spring, urges the 5 members apart.
When the i~plement is in the locked position, spring 7 presses (compare Figs. 1 and 4), against both abutments 11, 12, and 13, 14. Handle 4 together with its locking extension 9 fits into locking grooves 16, and locking lining 18 together with its locking elements 20, 21 meshes with locking means 22, 23 whereby the handle can be locked into its swivel and turning positions.
In order to be adjusted, handle 4 is slid in the longitudinal direction of pin 5 against the force of spring 7. As a result, spring 7 is compressed between abutments 11 and 13 or 12 and 14, and locking protrusions 15 of extension 9 slide out of locking grooves 16 of stationary pin 5. Locking protrusions 20 or 21 slide simultaneously out of locking protrusions 22 or 23 by virtue of the corresponding movement of locking lining 3 with handle 4 in the longitudinal direction of the pin.
Handle 4 is thus once moee able to tilt about its slewing axis 6 and simultaneously rotate with its lining 8 inside bearing casing 10 into any desired position about axis 5.
Spring 7 then pulls both joints (SG, DG) once again into the locked position in which locking protrusions 15 fit into locking grooves 16 and locking protrusions 20, 21 fit into locking protrusions 22, 23.
The handle can be adjusted with one hand. With the hand grasping handle 4, the fingers press upon holder 1 against the force of spring 7, thus permitting handle 4 to tiIt and rotate in relation to holder 1.
Release of holder 1 causes spring 7 to push both joints (SG, DG) automatically into the locklng positions.

8, the rotating joint (DG) can have in the zone of its upper edge facing the swivel joint (SG) the locking means, whereby teeth 28 are arranged on the rotating circum~erence of locking lining 8 and locking grooves 29 are arranged in bearing casing 10.
Holder 1, handle 4 and the locking lining 8 with its fork section are all formed from a single piece of synthetic material.
Pin 5, abutment collar 11 and neck 17 or lining 18 can, like locking plate 25 or securing ring 27, be produced from either synthetic material or metal;
abutment plate 13 can consist either of metal or a synthetic material.
Handle 4 of the hand implement shown in Figs. 9 and 10 exhibits a semicircular extension 9 comprising locking grooves 9a. The extension 9, supported by joint section 30 that is borne in bearing casing 10 and capable of turning about axis 5, is itself capable of slewing about the axis 6 that is oriented at an angle to the axis 5 of joint section 30. A lock-and-release pusher 31, capable of sliding back and forth parallel to axis 6, is arranged between axis 6 and the opposing edge of bearing casing 10, penetrates joint section 30 and features locking teeth 32, 33. Locking teeth 32 conspire with locking grooves 9a of extension 9, and locking teeth 33 conspire with locking grooves 34 arranged in bearing casing 10.
Locking grooves 34 are evenly distributed along the circumference of bearing casing 10, and the case-shaped joint section 30 exhibits guide grooves 35 in which pusher 31 is borne.
The lower case-shaped partial zone of joint section 30 is arrested at the underside of bearing casing 10 by means of a stopping lip 36.
Semicircular extension 9 similarly exhibits a plurality ~33~5 of grooves evenly distributed in an arc.
Lock-and-release pusher 31 is actuated by spring 7, which is capable of moving such pusher into and holding it in the locking position.
Forming part of lock-and-release pushec 31 is a guide 37 embodied as an abutment sleeve, into which one longitudinal end zone of spring 7 extends; the other longitudinal end rests against joint section 30.
Guide 37 extends between locking teeth 33 which ate capable of locking handle 4 during axial rotation relative to holder 1, and are oriented parallel to the longitudinal direction of the pusher.
Casing-shaped guide 37 simultaneously forms an abutment which serves to limit sliding motion of pusher 31, in that the guide 37 comes to rest against the inside of joint section 30 in the locked position.
Lock-and-release sliding element 30 is embodied as a cylindrical pin of circular cross section having opposed locking teeth 32, 33 for the rotating and slewing joints (DG, SG). Spring 7 is preferably embodied as a pressure spring (helical spring); such spring can, however, be embodied as a tension spring andj accordingly, be attached by both of its ends to an abutment of pusher 31 and to joint section 30.
In order to adjust the articulated head (rotating joint DG and swivel joint SG) that comprises extension 9, pusher 31 and joint section 30, as well as bearing casing 10, sliding element 31 is slid by hand against the force of the spring. The locking teeth 32, 33 can slide at the same time out of grooves 9a, 34, whereupon handle 4 together with its extension 9 can be slewed about axis 6, and with its joint section 30 rotated ins-de bearing ~ ~casing 10 about the axis 5 that is perpendicular the axis ; ~ 6. The stepwise angular adjustment of handle 4 is thus ~ ~ ~ 35 enabled in both directions relative to holder 1.
~ pon beinq released, sliding element 31, is automatically slid by spring 7 back into the locking position, the locking teeth 32, 33 fitting into grooves 9a, 34, and locking the device into the adjusted handle S setting.
