AI Technical Summary
Existing car window adjustment mechanisms using hand cranks are complex, costly to manufacture, and prone to frequent failures due to interlocking elements like threads and gears, leading to high production costs and reliability issues.
A simple drive device comprising a coupling disc with a nose engaging notches and a spring-actuated slider, allowing smooth operation by rotating the hand crank, which engages and disengages with the window tab through a sprocket wheel, reducing mechanical complexity and enhancing durability.
The device provides a reliable and cost-effective solution for adjusting car windows by minimizing mechanical complexity and improving durability, ensuring comfortable operation with reduced failure rates.
Description
[0001] Drive device for car windows. . For car windows of automobiles, railway carriages, etc., which are operated by means of a hand crank in their The height direction can be adjusted; it is already known that the gearbox can be automatically set in motion or stopped by the hand crank. to be able to move the carriage window and hold it in any position. These devices, being very limited in space, a somewhat simple design. Consequently, They are very expensive to manufacture, and moreover, they fail very often; because of various interlocking elements, such as threads, Gears and c11;1. are required.
[0002] The new device, which is very simple, is intended to remedy this problem. It essentially consists of only one The dome disc, which is moved back and forth by the handle, thereby engaging the chain wheel used to move the window. It rotates or holds in place. Despite its simple design, the device fulfills its purpose and can withstand rough handling. experience.
[0003] Essentially, the device consists of a dome disc with a nose, which can be locked into positions. <leg festen Fensterlasche eingreift und welche When the hand crank is turned, a spring slide fixed to the hand crank, which acts on the coupling disc, disengages it from the detents. The lier is blown out, while upon leaving the lower edges of the box, it can re-enter them due to the spring action of the slider. To your 1lettenra(1 dome noses are arranged which enter into incisions of the dome disk and are permanently coupled to the dome disk, so (Let the nose of the coupling disc disengage from the detents when releasing (let the sprocket rotate when turning the crank. For convenience, (leave Handle in (hand crank freely rotatable, so (the hand crank can be operated very comfortably).
[0004] The invention is illustrated in one embodiment, for example, in the drawing. Fig. i shows a view of the Drive unit with crank removed.
[0005] Fig. 2 shows a side view of Fig. i in partial section and with the crank attached. As the drawing shows, the hand-Z> i is located on the hand-Z> i A fixed slider 4, which is equipped with shoulders 2 and 3 - This slider 4 rests with its shoulders 2 and 3 on the pins 5 and 6. the coupling disc 7. The hand crank shaft i is equipped with a spring 8, both ends of which sit on the pins 5 and 6 of the crank disc 7. and which also presses the slide ,4 firmly against the coupling disc. When the hand crank shaft i is turned, the following acts, depending on the direction of rotation: one or the other of shoulders 2 and 3 against pins 5 and 6 of the cup disc 7, -and as a result, this will move upwards or downwards. lost. The Kulfpelx.heibe 7 has two slots 10, while the chain degree 12 is equipped with two lugs ii which fit into these slots io. intervene and provide guidance. The dome disc also has a nose 9, which can intervene in the opening 15 of the window flap 16. The noses ii The sprocket 1.2 must of course be designed in such a way that the coupling disc 7 can move freely on these lugs ii when their lug 9 is to be pushed out of the notches 15.
[0006] The process is now as follows: When stationary, the nose 9 of the cup disc 7 rests in a notch 15 of the window tab 16. If one now rotates At the crank 13, for example to the right, then the shoulder 3 of the scissor .1 is pressed against the pin 6. If this happens, then the The dome disc 7 is shifted downwards, so that the nose 9 pushes out of the notch 15 in which it is currently located. Is the nose 9 out If the corresponding stop 15 is pushed out, then of course the lateral stop is missing, which forced the dome disc to move, and the Coupling disk 7 will now be rotated. Since the two lugs ii on the sprocket 12 now lie in the slots io of the coupling disk 7, When rotating, the sprocket 12 is engaged and rotated along with it, until the nose 9 again meets a detent 15 and engages it again. snaps.
[0007] As the rotation continues, the coupling disk is pushed out of the detent again, then the coupling disk can retract. Turn the sprocket until the next 111'ast and so on.
Claims
[0008] PATt;NT-CLAIM: Drive device for car windows, characterized in that the shaft (i) (leg hand crank (13) with a lower is equipped with a spring-loaded shoulder sheath (4, 2, 3) which rests on a domed disc (7) which is engaged by means of a nose (9) in detents (15) of the window tab (16) can engage and also has slots (io) into which dome lugs (ii) provided for your sprocket (12) engage; so that when turning the hand crank (i3) the dome plate (7) is first displaced by the eccentric action of the shoulder disc (_.) with its nose (9) one of the detents (15) of the window tab (i6-) can be pulled out and then turned together with your I@ettenrad (12).
