Description
1 The present invention relates to a travelling carriage for strips of vertical blinds.
Travelling carriages of the above-mentioned general type are known in the art. A known tra~elling carriage has a housing and a pivot pin which is supported in the housing for pivoting about a vertical axis and is connected with a toothed rim whose teeth engage with the teeth of a mating member. The strips of a vertical blind are connected by their upper ends with the pivot pins of the travelling carriages, and the latter run in a bearing rail in a horizontal direction. In most cases, the carriages are provided with rollers which make easier the travelling of carri-ages, particularly in the event when vertical blinds of greater sizes are utilized. The pivot pins are supported in the upper wall and the lower wall of the housing at two locations near the engagement of their toothed rims with the teeth of the mating member, The mating member is formed as a worm gear, and together with the toothed rim of the pivot pins forms the pivot drive.
With the aid of the above-mentioned pivot drive, the pivot pins are rotated about their longitudinal axes, so that the strips can be turned in both directions about a vertical axis. Means is provided for preventing damage to the carriage during turning or pivoting movements of the strips, in the event that one or several strips meets a hindrance or in condition when the strips ~pproach each other being assembled at one side of the blind. This means is formed as a slipping clutch arranged between the pivot drive and the pivot pin. The slipping clutch in known constructions in-cludes a friction seat provided on the toothed rim of the pivot pin. Such a friction seat possesses, however, several disadvantages.
The frictional engagement of the coupling decreases in condition of frequent use of the latter. Since there are no constrained
Travelling carriages of the above-mentioned general type are known in the art. A known tra~elling carriage has a housing and a pivot pin which is supported in the housing for pivoting about a vertical axis and is connected with a toothed rim whose teeth engage with the teeth of a mating member. The strips of a vertical blind are connected by their upper ends with the pivot pins of the travelling carriages, and the latter run in a bearing rail in a horizontal direction. In most cases, the carriages are provided with rollers which make easier the travelling of carri-ages, particularly in the event when vertical blinds of greater sizes are utilized. The pivot pins are supported in the upper wall and the lower wall of the housing at two locations near the engagement of their toothed rims with the teeth of the mating member, The mating member is formed as a worm gear, and together with the toothed rim of the pivot pins forms the pivot drive.
With the aid of the above-mentioned pivot drive, the pivot pins are rotated about their longitudinal axes, so that the strips can be turned in both directions about a vertical axis. Means is provided for preventing damage to the carriage during turning or pivoting movements of the strips, in the event that one or several strips meets a hindrance or in condition when the strips ~pproach each other being assembled at one side of the blind. This means is formed as a slipping clutch arranged between the pivot drive and the pivot pin. The slipping clutch in known constructions in-cludes a friction seat provided on the toothed rim of the pivot pin. Such a friction seat possesses, however, several disadvantages.
The frictional engagement of the coupling decreases in condition of frequent use of the latter. Since there are no constrained
-2- ~
~1~13s~;
1 positions between the toothed rim and the pivot pin, the return movement of the strips to their initial positions poses a problem and is often responsible for non-uniform positions of the strips.
The clipping clutch requires a separate manufacturing process and makes difficult the mounting of the parts of the carriage with the pivot drive, so that the slipping clutch constitutes a considerable part of the manufacturing expenses of the carriage.
Accordingly, it is an object of the present invention to provide a travelling carriage for strips of vertical blinds, which avoids the disadvantages of the prior art.
More particularly, it is an object of the present invention to provide a travelling carriage for strips of vertical blinds, which provides for required safety of operation without utilization of a slipping clutch.
In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a travelling carriage having a housing, a pivot pin connectable with a strip and pivotable about a vertical axis, a mating member pivotable about a horizontal axis and pivoting the pivot pin, wherein the pivot pin is supported in the housing tiltable with respect to the vertical axis, so that the pivot pin can disengage from the mating member upon tilting. Thereby, the drive of the pivot pin is interrupted and the pivot pin, together with the strip carried thereby, no longer pivots about the vertical axis .
In accordance with advantageous features of the present invention, the pivot pin is supported in a lower wall of the housing in a floating manner, so that the pivot pin, under the action of elastic deformation of the housing wall and/or the utilization of ~ .~
1~61356 1 a respectively dimensioned play, can tilt laterally and thereby interrupt the engagement between teeth of a toothed rim of the pivot pin and teeth of the mating member.
This solution possesses the disadvantage, as compared with the slipping clutch, that the material tension of the de-formed housing wall always acts in direction towards the teeth engagement. Thereby the deviation of the strip position from the normal position because of a hindrance of the like always corresponds to a tooth pitch or a multiple of the same. A known return member which in most cases acts at a pile location of the strips, can return the strips by this predetermined deviation to their normal position.
The considerable advantage of the travelling carriage in accordance with the present invention is that it no longer requires a particular slipping clutch, and that the safety member of the inventive construction is not subjected to the action of undesir-able wear. In order to provide for desired elastic deformability of the housing and to substantially determine the material tension, the housing is constituted of a suitably synthetic plastic mater-ial and is U-shaped as seen in a side view. The housing has a shell-shaped upper wall which is located at a radially opposite side of the pivot pin (at one side of which the mating member is located) and forms an abutment for an upper portion of the pivot pin.
In accordance with still another feature of the present invention, the pivot pin is provided inside the housing with an abutment member constituted of a synthetic plastic material and fixedly connected with the pivot pin, preferably of one piece with the latter. The housing is, in turn, provided with an abutment against which the abutment member of the pivot pin abuts in the 1 end positions of the latter. For making easier the mounting of the parts of the carriage, and making simple the manufacture of the same, the pivot pin can be manufactured of one piece with the above-mentioned abutment member and inserted into the housing from above through an open upper side of the housing. During this insertion, the deformability of the lower housing wall of the carriage is utilized.
A further feature of the present inven~ion which ad-ditionally contributes to the purpose of making simpler the manu-facture of the carriage is embodied in the fact that the pivot pin at its lower end is provided with eccentricland one-sided enlarge-ment, and the housing in its lower wall is provided with a respec-tive eccentric and one-sided recess of a bearing opening for the pivot pin, the recess corresponding to the above-mentioned enlarge-ment. This construction provides for an increased supporting face of the pivot pin for the strip at the location of hanging of the latter, which is advantageous for the force transmission. In addi-tion, it allows the above-mentioned mounting of the pivot pin from above through open upper side of the housing.
The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims.
The invention itself, however, both as to its construction and its method of operation, together with additional objects and advan-tages thereof, will be best understood from the following descrip-tion of preferred embodiments when read in connection with the accompanying drawing.
FIG. 1 is a side view of a blind formed as a vertical jalousie;
FIG. 2 is a view showing a vertical section of a tràvel-ling carriage in accordance with the present invention;
1 FIG. 3 is a side view of the housing of the travelling carriage of FIG. 2;
FIG, 4 iS a view showing a section taken along the line IV-IV of FIG. 2;
FIG. 5 is a view showing a section taken along the line 5-5 of FIG. 2;
FIG. 6 is a side view of the pivot pin of the carriage in accordance with the present invention, in direction of the line 6-6 in FIG. 2.
FIG. 1 shows a vertical blade which has a bearing rail 2 provided with mounting means, and a plurality of strips 1 which hang from the bearing rail and move relative to the latter. The strips 2 can be disp~ced laterally, for example, by a rope 3, and can pivot about their vertical axes by a chain 4. A travelling carriage for each strip 1 displaces in the bearing rail 2 in sliding or prefereably rolling manner.
The travelling carriage has a housing identified by reference numeral 5 and a pivot pin 6 identified by reference numeral 6 and supported in the housing 5 pivotally about a vertical lon-2a gitudinal axis of the pivot pin. The ~ivot pin 6 carries atoothed rim 7 whose teeth engage with the teeth of a mating member formed as a worm gear 8. The worm gear 8 is axially displaceable on a spline shaft 9 which is pivotable and actuated by the chain 4.
The housing 5 is U-shaped as seen in a side view, and has an open upper side, One leg of the housing 5 serves as a sup-port for the worm gear 8. The pivot pin 6 is mounted only in a lower wall 10 of the housing 5 and thereby is supported in a float ing manner. The housing 5 and more particularly its lower wall 10 is constituted of an elastically deformable synthetic plastic ma-terial. In addition, the wall 10 is profiled so as to contribute _~_ 11~1356 l to the elastic deformation of the same and make easier its de-termi.nation in the respective construction of the carriage.
When one or several strips, for example, meet a hindrance, the pivot pin 6 can be tilted with respect to the vertical axis so that the teeth of the pivot pin 6 disengages from the teeth of the worm gear 8.
The pivot pin 6 may extend through an opening in the lower wall 10 with a respective play so as to further allow the above-mentioned tilting of the pivot pin 6 about the tilting axis. The housing 5 has an upper leg which is located at one side of the pivot pin 6, the one side being opposite to the side at which the worm gear 8 is located. The upper leg is formed as a ~upporting shell for an upper end portion of the pivot pin 6.
The pivot pin 6 is provided with an abutment member 11 which is arranged to abut against an abutment 12 of the housing 5 in end positions of the pivotal movement of the pivot pin 6.
The pivot pin 6 has a lower end portion provided with a hook structure 13. The strip 1 with its ear is suspended from the hooked structure 13. The contact face of the pivit pin 6 with the strip l is provided on a one-sided e-centric enlarge-ment 14, to improve force transmission between the pivot pin 6 and the strip 1. A bearing opening formed in the lower wall 10 for receiving the pivot pin 6 is provided, with a recess 15 which corresponds to the above-mentioned enlargement 14.
When during mounting of the carriage the pivot pin 6 is in-serted into the housing from above through the open upper side of the same, the enlargement 14 extends through the recess 15 as can be seen from the drawing.
It will be understood that each of the elements described 5~
1 above, or two or more together, may also find a useful application in other types of constructions differing from the types described above.
While the invention has been illustrated and described as embodied in a travelling carriage for strips of vertical blinds, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
