Definitions

  • a laundry drier includes a drum which is mounted for rotation in two opposite directions.
  • a plurality of elongated flexible lines are secured to the drum at axially spaced points and arranged to be wound onto the drum when it rotates in one direction and to be unwound when it rotates in the opposite direction.
  • a biasing spring permanently urges the drum to rotate in the direction inwhich it winds up the lines.
  • Arresting means is operable for arresting the drum from rotation in the direction unwinding the lines and actuating means is located axially adjacent one end of the drum and has limited freedom of movement axially of the drum between a first position in which it engages the drum for rotating the same, and a second position in which it is disengaged from the drum.
  • the present invention relates generally to laundry driers, and more particularly to the type of laundry drier provided with one or more lines which may be extended for hanging laundry thereon for drying purposes.
  • Laundry driers of this type are already known. They suffer, however, from various disadvantages including their rather complicated construction, the correspondingly expensive manufacture and assembly, and the susceptibility to mechanical malfunction which inevitably results in a complicated construction. Furthermore, the arresting arrangements provided in these prior art constructions are complicated and not entirely reliable. Such arresting arrangements in these constructions may arrest the line when it is desired to withdraw it from the device, and on the other hand, it may release the line when pull is exerted on it by laundry which has been hung on the line.
  • a further object of the invention is to provide such a laundry drier which is simple in its construction and therefore inexpensive to manufacture.
  • An additional object of the invention is to provide such a laundry drier which is free from malfunctions and which requires no maintenance.
  • a concomitant object of the invention is to provide such a laundry drier which is provided with reliably operating arresting means.
  • one feature of the invention resides in the provision of the device of the type under discussion which comprises a drum mounted for rotation in a first and an opposite second direction, and at least one elongated flexible line which is secured to the drum and is arranged to be wound onto the latter when the drum rotates in the first direction and to be unwound when the drum rotates in the second direction.
  • Biasing means is associated with the drum and permanently urges the same for rotation in the first direction.
  • Arresting means is operable for arresting the drum front rotation in the second direction.
  • Actuating means is arranged axially adjacent one end of the drum and has limited freedom of movement axially of the latter between a first position in which it engages the drum for rotating the same, and a second position in which it is disengaged from the drum.
  • FIG. 1 is a longitudinal section through one embodiment of the invention
  • FIG. 2 is a section taken on the line IIII ofFIG. 1;
  • FIG. 3 is a section taken on the line IIIIII of FIG. 1;
  • FIG. 4 is a front view of a component element of the device shown in FIG. 1;
  • FIG. 5 is a longitudinal section, partly broken away, through a device according to our invention and illustrating a second embodiment
  • FIG. 6 is a view similar to FIG. 5 but illustrating still another embodiment of the invention.
  • the device in mm is identified with reference numeral 10. It comprises at its opposite axial ends two end plates 11 and 12 whose rearward portions 13 and 14 are angled in outward direction. Thepurpose of this is to secure the device 10 to a support, such as a wall or the like, via the portions 13 and 14. These portions are provided with openings 15, as illustrated in FIG. 4, through which securing or mounting elements can be extended to be secured in the support, and it will be appreciated that the openings 15 may be of any desired configuration, for example keyhole shaped.
  • a tubular support 18 is provided which is rigidly connected with the end plates 11 which for this purpose are provided .with central openings 16 and 17, respectively, from whose circumference the projections 19 and 20 extend substantially radially through cutouts 21 provided in the support 18 and to prevent the same from rotation and from axial shifting relative to the end plates 11 and 12.
  • a helical spring 22 surrounds the support 18 and has one end extended through a cutout 23 in the support I8 so as to be connected with the latter.
  • the other end of the spring 22 is connected to a projection 24 of a coupling member 25 of substantially cup-shaped configuration so that the spring is prevented from rotating with reference to the coupling member 25.
  • the spring could of course be of other than helical configuration.
  • the coupling member 25 is provided with a collar 26 with which it is turnably mounted on the support 18; it further has an outwardly extended region 17 which accommodates one end of a drum 28 onto which the one or more elongated lines are to be wound.
  • the elements 25 and 29 are connected with the drum .28 in such a manner as to rotate therewith but not relative thereto. This is in the illustrated embodiment of FIGS. 1-4 accomplished by screws 30 which extend through the drum 28 and into tapped bores of the elements 25 and 29, these bores not beingspecifically illustrated.
  • the member 29 could also be configurated in a different manner, if desired and this will be evident to those skilled in the art.
  • plurality of elongated lines 31 which may consist of any suitable material such as rope, synthetic plastic material or the like, are to be wound onto the drum 28. Their inner ends are connected to the drum 28 via lugs 32 portions of which extend through slots into the drum 28 and are connected thereto by screws 33. The opposite or free ends of the lines 31 are passed through holes in an elongated pull bar 34, as clearly shown in FIG. 2, and are secured therein by knotting, as also seen in FIG. 2. It should be pointed out that only a single one of the lines 31 is illustrated in the drawing, but this is done for the sake of clarity and several such lines are provided in the illustrated embodiment.
  • the coupling element 25 has a radially extending peripheral portion 35 abutting against the end plate 11 and is provided with cutouts 36 which are arranged in identical spacing from the support 18 and into which a coupling portion 37 which is rigid with a handle 38, can selectively be extended.
  • the handle 38 is turnably mounted via a pin 38 or shaft 39 which extends into the support 18.
  • the shaft 39 is provided with a longitudinally extending recess 40 one end of which merges with a circumferentially extending recess annulus 41.
  • the projection 19 provided on the end plate 11 extends into the annular recess 41 the latter being so dimensioned that the shaft 39 and the .handle 38 are shiftable axially of the drum 28 through a predetermined distance.
  • the purpose of the elongated recess 40 is to permit the introduction of shaft 39 to the the tubular support 18 beyond the projection 19.
  • the handle 38 and the shaft 39 are of one piece, advantageously consisting of synthetic plastic material.
  • a collar 42 is provided on the handle 38 and extends in direction towards the end plate 11, being provided with an interior annulus of teeth 43.
  • a pawl 44 is mounted at the exterior side of the end plate 11 tumably via the bolt 45, and the turning movement of the pawl 44 in the direction towards the annulus of teeth 43 that is limited by an abutment 45 in such a manner that the engagement of the pawl with the teeth is just possible to the extent that it can reliably prevent rotation of the handle 38 when such engagement has taken place.
  • the end plate 11 is provided with a curved slot 46 which can register with the cutouts 36 of the coupling element 25 and which is at its middle region enlarged.
  • the coupling portion 37 of the handle 38 extends through the curved slot 46 and, when the handle 38 is moved to its axially inner position, the coupling portion 37 also extends into one of the cutouts 36 of the coupling element 25.
  • the coupling portion 37 does not extend into any of the cutouts 36 of the coupling element 25, but still extends into the curved slot 46. This is clearly shown in FIGS. 2 and 3.
  • the handle 38 When the handle 38 is withdrawn to its axially outer position, it is no longer coupled with the drum 28 so that the lines 31 can be withdrawn from the latter by exerting pull on the pull bar 34. This results in tensioning of the spring 22 because of the fact'that the opposite ends thereof are respectively coupled with the support 18 and the drum 28.
  • the pull bar 34 may be connected to a suitable support, such as a wall or the like, via a handle portion 47 (compare FIG. 2) which is retractable into the pull bar.
  • the handle 38 When this has taken place, and it should be understood that it can take place because the handle 38 is moved to its axially outer position in which at the same time the annulus of teeth 43 is so far spaced from the pawl 43 that they do not engage, the handle 38 is turned in a sense in which the linesare further unwound until the end position is reached which is determined by cooperation of the coupling portion 37 and the curved slot 46. Thereupon, the handle 38 is moved to its axially inner position so that the coupling portion 37 also extends through one of the cutouts 36 in the coupling element 25 whereupon the handle 38 is turned in opposite direction, that is in a sense winding the lines 31 onto the drum 28 until the lines have been tensioned to the desired extent.
  • the handle 38 While the lines 31 are to be rewound onto the drum 28, the handle 38 is axially shifted to its axially outer position, whereby the cooperation between the pawl 44 and the teeth of the annulus 43 is interrupted, while simultaneously the cooperation between the handle 38 and the drum 28 via the coupling element 25 is terminated. This permits the spring 22 to rotate the drum 28 in a sense winding the lines 31 back onto the drum 28.
  • a housing is provided consisting of shell sections 48 and 49 which serve to protect the components of the device located between the end plates 11 and 12.
  • the shell sections 48 and 49 extend from one to the other of the end plates 11 and 12 and are secured thereto in suitable manner which is not specifically illustrated.
  • the rear side of the housing that is the side which will normally face a support on which the device is to be secured, is substantially open and covered only by angled marginal portions 50 and 51 of the shell sections 48 and 49.
  • the drawing shows that the marginal portion 50 of the upper shell section 48 is downwardly and outwardly inclined and that the marginal portions 51 of the lower shell section 49 approximately parallels the inclination of the marginal portion 50 whereby, as clearly shown in FIG. 2, the moisture running off the other side of the housing is prevented from running into the interior of the housing.
  • the front side. of the device that is the side at which the line or lines are extended, is provided with a recess for accommodating the pull bar 34.
  • the recess is identified with reference numeral 52 and the end plates 11 and 12 are provided with two lugs 53 and 54 constituted by portions of the end plates 11 and 12 which are cutouts cutor stamped out and bent inwardly at a substantially right angle, as shown.
  • the lugs are located one behind the other and spaced from one another at a distance corresponding to the breadth of the pull bar 34.
  • the foremost lugs 53 are so dimensioned and arranged that when the pull bar 34 is located in the recess 52,-they are located substantially in the plane of its outer face, whereas the rearmost lugs 54 are longer and serve as abutments for the pull bar 34.
  • the arrangement of the shell sections 48 and 49 is such, as illustrated in the drawing, that no moisture can enter into the housing through or in the region of the recess 52 either.
  • Caps 55 and 56 of nonoxidizable material serve to cover the end plates 11 and 12.
  • the cap 55 is provided with an opening through which the annulus 42 of the member 38 can just pass, and is provided with an outwardly extending collar 57 which extends beyond the annulus 42 to the outside.
  • the collar 57 may also serve to guide the handle 28, if necessary and desired.
  • the second cap, the one identifiedwith reference numeral 56, is not so apertured.
  • the caps 55 and 56 can be secured in suitable manner to the end plates 11 and 12, for instance by screw threads or the like to the end plates.
  • Recesses 58 are provide in the caps 55 and 56 in those edge portions thereof which face the lugs 13 and 14 of the end plates 11 and 12 and which embrace projections 59 provided on these lugs so as to afford proper alignment and quick assembly.
  • FIGS. 5 and 6 and more particularly that of FIG. 5, it will be seen that the embodiment of FIG. 5 is in most respects similar to that of FIGS. 1-4, with identical reference numerals identifying identical components. It is emphasized that certain portions are omitted, that is those portions that are shown in FIG. 1 at the left-hand side thereof, because they are identical with the ones shown in FIG. 1.
  • the embodiment in FIG. 5 differs, as will be seen, from that of FIG. 1 in that the pin 60 shown herein is provided with an elongated annular recess 61 bounded by annular shoulders 62 and 63.
  • the recess 61 straddles a tubular portion 64 which is stationarily mounted in the member 65 and which is shorter than the length of the recess 61 to permit axial shifting of the pin 60 and the handle 38 associated with it. Axial movement of the handle 38 is limited by cooperation of the tubular portion 64 with the annular shoulder 63 where axial withdrawal of the handle 38 is concerned. Beyond the annular shoulder 63 thepin 60 conically tapers towards its end, as shown.
  • the pin 60 is hollow and provided with a longitudinal slot 66 extending inwardly from its end and approximately to the middle of the recess 61.
  • the pin 60 in this embodiment consists of springy material which makes possible its introduction into the member 65 even if the tubular portion 64 is stationarily mounted previously, because when the pin 60 is inserted, the ribs 67 are inwardly deflected to the diameter of the tubular portion 64 when they engage, on introduction of the pin 60, the conical surfaces 68 provided for this purpose.
  • a withdrawal of the pin 60 is precluded-insofar as unintentional withdrawal is concerned-by cooperation with the annular shoulder 63 with the juxtaposed end face of the tubular portion 64.
  • the embodiment of FIG. 6, finally, differs from the preceding embodiments in that the diameter of the pin 71 associated with the handle 38 corresponds substantially to the outer diameter of the member 70 corresponding to the member 65 in FIG. 5.
  • the member 70 is provided with radially projecting hooks 72 which extend into longitudinal slots 73 provided on the member 70.
  • the pin 71 is hollow, as in the embodiment of FIG. 5, and provided with one or more slots 74 extending inwardly from its end and making possible an elastic deflection in the region of the hooks 72. This makes it possible to introduce the pin 71 into the member 70 without any difficulty.
  • each such individual support member serves to turnably support one end of the drum, only one support member having to be hollow to accommodate the pin of the respective handle.
  • a device of the character described, particularly a laundry drier comprising in combination, a drum mounted for rotation in a first and an opposite second direction and including tubular support means supporting said drum for such rotation; at least one elongated flexible line secured to said drum and arranged to be wound onto the latter when said drum rotates in said first direction, and to be unwound when said drum rotates in said second direction; biasing means permanently urging said drum for rotation in said first direction;
  • actuating means arranged axially adjacent one end of said 7 drum for rotating the same; arresting means for arresting said drum against rotation in said second direction; and cooperating abutment means provided on said support means and said actuating means, said abutment means including abutment portions provided on said support means and spread resiliently compressible hook portions provided on said actuating means and arranged to cooperatively engage with said abutment portions and at least limit displacement of said actuating means with reference to said drum.
  • said actuating means being movable to and from a position engaging said drum for rotation, and said drum and said actuating means being provided with cooperating coupling portions arranged to interengage with each other when said actuating means is moved to said position.
  • said biasing means including a helical spring coaxial with said drum and having an end portion rigid with the same.
  • said actuating means having a shaft mounted for turning movement coaxially with said drum and shiftable axially relative thereto, said shaft being provided in its periphery with an axially elongated recess; and further comprising a projection on saiddrum extending into said recess for limiting the extent of movement of said actuating means.
  • said drum including an end plate extending transversely to its axis and provided with said recess, and said recess including an elongated first portion and an annular second portion merging with one end of said first portion.
  • said actuating means further including a handle adapted to be gripped by the fingers of a user, and said handle being rigid with said shaft.
  • said first arresting portion being configurated as an internal annulus of teeth
  • said second arresting portion comprising a pawl arranged to cooperate with the teeth of said annulus.
  • a device as defined in claim 1 said line having a free end portion; and further comprising a pull bar secured to said free end portion arranged to be gripped by a user for exerting pull on said line to thereby unwind the same from said drum by effecting rotation of the latter in said second direction in response to such a pull.
