Holding device adapted to be attached to a building wall for holding objects or to be gripped by a person
A holding device is designed to be attached to a building wall, and in particular in a bathroom, using a suction means having at least one suction head with a sucker disk and an actuating means for the sucker disk so that the suction means may be attached to and detached from the building wall manually on operation of the actuating means. The suction means bears a bearing unit able to be pivoted about a pivot axis parallel to the building wall. The bearing unit bears a support bar extending perpendicularly to the pivot axis for holding objects or to be grasped by persons
The invention relates to a holding device adapted to be attached to a building wall and in particular in a bathroom, comprising an attachment means able to be attached to the building wall and a support bar for holding objects or to be gripped by persons, and which, when the attachment means is attached to the building wall extends in a position of use into the space delimited by the building wall.
THE PRIOR ARTSuch holding device are for example employed to hold a curtain, when a seated person is to be given a shower and washed by another person. The curtain is located generally at hip level between the two persons and is intended to keep the clothing of the one person from being splashed. Furthermore the seated elderly or disabled person may grasp the support bar to stand up.
The known holding devices are permanently secured to the building wall. The result of this is that after use the support bar may be disadvantageously placed having regard to on local features or the height of the persons. Moreover, the support bar extending into the room may be an obstruction when not in use. The support bar itself might even be in the way if it is able to be pivoted to the side. In bathrooms and the like space is normally at a premium so that folding the bar to the side is frequently not possible.
SHORT SUMMARY OF THE INVENTIONOne object of the invention is accordingly to devise a holding device of the type initially mentioned which is adaptable to different functions and when not in use is not an obstruction.
In order to achieve these and/or other objects appearing from the present specification, claims and drawings, in,the present invention the attachment means comprises a suction means with at least one suction head with a sucker disk and an actuating means for the sucker disk so that the sucker disk and with it the associated suction head may be manually caused to suck firmly on the building wall and be released from it, and the suction means carries a bearing unit able to be pivoted about a pivot axis parallel to the building wall, such bearing unit holding the support bar extending perpendicularly to the pivot axis.
A precondition for the attachment of the holding device in accordance with the invention is a flat wall. This condition will be fulfilled in a bathroom which is normally tiled and the suction means may be mounted on the tiles at any desired position for adaptation to different uses, different spatial circumstances and persons of different height. The position of the holding device may be reset whenever required without any difficulty. It is merely necessary to operate the actuating means by hand.
Since the support bar may be pivoted at the bearing unit the grip or support bar may be shifted toward the wall into a non-use position out of the way. In this respect the lack of space may be taken into account by moving the holding device out of the way against the wall.
Furthermore the pivot axis does not need to be vertically aligned. The suction means may be in fact positioned at any angle on the building wall so that the pivot axis may also be set horizontally or at any desired angular position betwixt horizontal and vertical.
It will be clear that the support bar may also be employed to hold any other desired objects, which are to be pivoted toward or away from a person when standing, seated or prone. In this case as well the holding device can be set at the respectively most convenient position on the building wall.
The multiplicity of possible applications furthermore includes the possibility of designing the support bar to be grasped by a person and providing it with a handle means. For instance, the suction means may be so positioned on the wall that the support bar extends toward a seated person, who may then grasp the handle means of the support bar and pull himself or herself upward to stand up.
Further useful developments of the invention are defined in the claims.
Further advantageous developments and convenient forms of the invention will be understood from the following detailed descriptive disclosure of embodiments thereof in conjunction with the accompanying drawings.
The holding device 1 appearing in the drawings is illustrated in
In this context the holding device 1 possesses an attachment means which is constituted by a suction means 2. The suction means 2 comprises two suction heads 2 and 4, which respectively include a sucker disk 5 and a manually operated actuating means 6. The two suction heads 3 and 4 are identical in design so that the said reference numerals only appear in the case of the sucker disk 3. The respective sucker disk comprises a rubber-like flexible material and is arranged on the bottom side of the respective suction head 3 and 4. The sucker disk 5 projects past the suction head housing 7 right the way around it, the housing 7 having a cavity into which the middle portion of the sucker disk 5 may be drawn upward. When pulled upward the outer portion of the sucker disk 5 bears against the bottom side of the suction head housing 7.
The actuating means 6 is assigned to the respective sucker disk 5 and can be shifted between an inactive and an active position. In the inactive position the sucker disk 5 rests loosely on the suction head housing 7 and is not urged toward the suction head housing 7. In the active position of the actuating means 6 the sucker disk 5 is on the other hand drawn up toward the suction head housing 7.
The actuating means 6 comprises an actuating lever 8 able to be tilted between the active position and the inactive one. In the drawing the actuating lever 8 is illustrated in its active position in which the sucker disk 5 is pulled upward. The pivoting movement of the actuating lever 8 is converted by way of an eccentric means into the upward movement of the sucker disk 5.
For the attachment of the suction means 2 and accordingly of the holding device 1 on the respective building wall the suction heads 3 and 4 are put on the wall with the actuating 8 lever in the inactive position. When the sucker disks 5 are on the building wall the actuating lever 8 is pivoted into its active position so that the sucker disk 5 (whose outer portion is still thrust against the building wall by the suction head housing 7) has its middle portion drawn away from the building wall. Accordingly vacuum is produced between the building wall and the sucker disk 5 so that the respective suction head 3 and 4 is held fast on the building-wall. For releasing the respective suction head 3 and 4 from the building wall the actuating lever 8 is pivoted back into the inactive position so that the sucker disk 5 is relieved and the respective suction head can be shifted clear of the building wall. In this respect it may be necessary to lift the edge of the sucker disk 5 at some point briefly so-that air from the surroundings may find its way underneath the sucker disk.
Such suction means are known and are f.i. described in the European patent publication EP 1 183 981 A2 so that a more detailed description is not required.
The building wall must be sufficiently even at the attachment point for the suction means 2. This is the case with tiled walls if the suction heads 3 and 4 are not put on joints between the tiles.
It is to be pointed even at this stage that the suction means may instead of having two suction heads in principle may also have only a single suction head or more than two suction heads.
The holding device 1 furthermore has a bearing unit 9 which is borne by the suction means 2. The bearing unit 9 is pivotally connected with the suction means 2 for pivoting about pivot axis parallel to the attachment plane defined by the sucker disks 5 (see
The support bar 11, as indicated in
In the working embodiment there are two possibilities of attachment for the support bar 11 on the bearing unit 9, as will be later explained in detail. In the case of the
In the case of
The pivot axis 10 is defined by a pivot axle element 13. The pivot axle element 13 possesses a circularly round cross section and may be constituted by a piece of tubing or may be solid. The two suction heads 3 and 4 are connected with each other by way of the pivot axle element 13. The bearing unit 9 is arranged between the two suction heads 3 and 4 and is therefore supported in a pivotal fashion on the pivot axle element 13. For this purpose the bearing unit 9 has a through bearing recess 14 through which the pivot axle element 13 extends.
The pivot axle element 13 is detachably connected with the two suction heads 3 and 4 so that there is a modular design. In this respect the pivot axle element 13 is plugged to the suction heads 3 and 4 detachably. Furthermore the pivot axle element 13 may be connected detachably with the suction heads 3 and 4 by detent means.
In the case of each suction head 3 and 4 the suction head housing 7 exhibits a plug receiving recess 15 and respectively, 16, aligned with the direction of the pivot axis 10, into which the pivot axle element 13 is plugged after the bearing unit 9 has been attached by plugging. For the detachable detent connection of the pivot axle element 13 in the plug receiving recesses 15 and 16 the pivot axle element 13 may have a spring loaded detent or catch element 17 and, respectively, 18 at its two end portions fitting into the plug recesses, such detent element protruding from the outer periphery and being adapted for cooperation with a detent hole 19 in the wall of the plug recess 15 and, respectively, 16. In the drawing,
In principle the two suction heads 3 and 4 could be omitted. As regards strength however two suction heads 3 and 4 with a bearing unit 9 arranged between the suction heads are advantageous.
The rotary bearing recess 14 is stepped at both end so that it has end portions 20 and 21 with an increased diameter. During fitting together the circular part of the suction head housing 7, which surrounds the respective plug receiving recess 15 and 16, is plugged into the end portion 20, respectively, 21 of the rotary bearing recess 14.
To secure the bearing unit 9 in the axial direction each suction head 3 and 4 constitutes a terminal abutment 22 and 23 (see
The bearing unit 3 and the support bar 11 together with it should be able to be secured in the respective position of pivoting the pivot axle element 13 or, respectively, come to a halt in the desired pivotal setting. For this purpose there is a securing means effective between the bearing unit 9 and the pivot axle element 13 to hold the bearing unit 9 in various different angular position on the pivot axle element 13.
This could in principle be ensured if there is a set screw screwed through the bearing unit 9, such screw being able to be turned from the outside to act on the pivot axle element 13. But this possibility would however entail detachment and tightening of the set screw at every time the pivot axle element's angle is reset.
A more convenient arrangement would therefore be one in which the rotary bearing recess 14 has a friction pad 24 so that although the bearing unit 9 may be turned on the pivot axle element 13, it is automatically held in the respective position of pivoting owing to the friction. The friction pad could also be provided on the pivot axle element. It would furthermore be possible for both the rotary bearing recess and also the pivot axle element to have a friction pad.
In addition to the friction pad 24 or in lieu of the friction pad the holding means could also be constituted by a releasable rotary/detent connection means. This means that in certain angular positions of the bearing unit 9 a detent engagement with the pivot axle element 13 is produced, the detent connection being overcome by the user's exerting a sufficiently large pivoting force so that the bearing unit 9 can be swung into the next predetermined pivot position.
In the working embodiment illustrated the rotary/detent connection is constituted by peripherally distributed detent recesses 25 in the wall of the rotary bearing recess 14, such recesses being provided with a resiliently supported detent member 26 (see
In the working embodiment illustrated the end face of the detent member 26 is convex in form. Accordingly the detent recesses 25 have a cross section in the form of a circular arc as is depicted in
The detent recesses 25 could be constituted by detent grooves 27 which are continuous in the axial direction. This is more particularly advantageous as regards manufacturing technology.
In principle the arrangement could also be contrived with a mechanical reversal of parts with the detent member arranged in the wall of the rotary bearing recess and the detent recesses in the pivot axle element.
The bearing unit 9 possesses two plug sockets 28 and 29 which are normal to the pivot axis 10 and hence normal to the pivot axle element 13,and are provided for the facing end of the support bar 11 so that the support bar can be plugged into the one or the other of the plug sockets 28 and 29 and secured there. In principle it would be possible as well to secure two support bars 11 in one of the two plug sockets 28 and 29.
Moreover, as a modification of the illustrated working embodiment it would be possible for the bearing unit 9 to have but one single plug socket 28 or, respectively, 29.
The two plug sockets 28 and 29 are at a right angle to each other.
One of the two plug sockets 28 is constituted by a through hole 30 arranged spaced from the pivot axis 10 and accordingly alongside the pivot axle element 13. The through hole 30 therefore extends parallel to a tangent to the rotary bearing recess 14. In this case the support bar 11 may be completely inserted right through the through hole 30 accordingly the through bearing unit 9 so that its end portion 31 (see
The wall abutment 32 arranged in front of the bearing unit 9 means that the bearing unit 9 and with it the support bar 11 can only be pivoted in the respective direction until the wall abutment 32 strikes the building wall on which the holding device 1 is fixed. This will be seen from the
The wall abutment 32 is able to be adjusted in the longitudinal direction of the support bar 11 so that there is an adjustable limiting effect for the support bar 11. Furthermore a wall abutment element 33 can be arranged on the support bar end which is adjustable in the longitudinal direction of the support bar. In
Another possibility for the adjustment of the wall abutment is such that the support bar 11 is able to be slid in the longitudinal direction and secured in the respective longitudinal position in the through hole 30. This can for example be effected by having a set screw screwed in through the bearing unit 9 and acting on the support bar 11. This design is not depicted.
In the case of the other plug socket 29 of the bearing unit 9 it is a question of a blind hole 35 which is radial in relation to the pivot axle element 13. In the case of the use in accordance with
The support bar 11 is in both possible applications arrested in the through hole 30 or, respectively, in the blind hole 35 releasably. For this purpose it is possible to have a detachable detent for holding in place apart from the above described possibility of the use of a set screw for adjustment of the longitudinal position of the support bar. For this purpose a detent element 36 can be arranged on the support bar 11 which corresponds to the detent elements 17 and 18 of the pivot axle element 13, such detent element 36 being urged by spring force outward. For the detent element 36 there is a cooperating detent hole 37 in the bearing unit 9, into which the detent element 35 snaps. The snapped home detent element 36 is—since the detent hole 37 opens to the outside—accessible from the outside so that the detent element 36 may be urged out of the plug socket inward for withdrawing the support bar 11. It will be clear that the detent hole 37, like the detent hole 19 described above, constitutes an annular surrounding abutment face 38 on which the detent element 36 abuts.
The detent hole 37 may as in the working be so arranged that the detent element 36 fits into the same detent hole 37 irrespectively of whether the support bar 11 is fitted in the through hole 30 or the blind hole 35.
The bearing unit 9 constitutes a pivot axis bearing portion 19 and a bearing portion 40 extending sideways from the pivot axis bearing portion, such portion 40 having in it the through hole 30 and the blind hole 35. The support bar bearing portion 40 preferably has a square block-like configuration. The pivot axis bearing portion 39 is radiused at the side opposite to the support bar bearing portion 40 so that the pivoting about the pivot axis element 13 is not impeded. The bearing unit 9 can be a single integral molding.
