This invention relates to sliding windows, more particularly windows for power driven vehicles or the like which are capable oi being pushed out partly from their guiding means and which do 5 not come into contact with the guiding bars connected to the coachworl; directly but are only connected therewith at isolated points through the intermediary of guiding members.

The invention consists substantially in this that the guiding members, oi which for example two are provided for each side of the window, are secured to the window or to the guiding bars in such a manner that in every position of the window the greatest possible guide length is provided for the window by means oi the guiding members.

In the case of a trapezoidal window having a straightY edge and a bent-over inclined edge, such an arrangement of the guiding members is provided by fitting on the straight edge of the window an upper guiding member rigidly connected with the window guiding means and a guiding member connected with the window or with the slidable window frame and sliding therewith, while on the side of the inclined edge oi the window the guiding is e-iiecteol by means oi' two guidingneinbers connected to the window.

The window glass is preferably framed in a metal frame of channel section, the sides of which are guided in channel section iron guide rails let into the door posts. Between the window frame and the guidinrx rails, the slide members are inserted, said slide members being made preierably of a sound damping material, for instance ResiteX. These slide members are only short in comparison to the entire guiding path, so that the resistance oiifered when opening and shutting the window is low. As the slide members are made of a relatively elastic material, they provide a secure setting for the window so that chattering is prevented with certainty.

A constructional example of the invention is illustrated by way of example in the accompanying drawing in six iigures, in which Figure l shows the door viewed from the inside,

Figure 2 shows a horizontal door,

Figure 3 shows a longitudinal section through the left hand side or the door on a larger scale,

Figure 4 shows a horizontal section through the guiding and slide members on a larger scale and Figures 5 and 6 show the securing of the sliding members on a larger scale.

Referring to the drawing the glass pane cc is framed by a metal frame b of channel section.

55. The two side members of the metal frame b are section through the Y guided in the channel section rails c which are let into the door posts l. Between the window frame b and the guiding rails c, slidemernbers c, j and gf, preferably made of sound damping material, for instance Resitex, are inserted.

On. each side oi the window a slide member is provided at the lower end of the window frame and a slide member at the upper end of the window frame.

f in the constructional example illustrated, a trapezoidal window is shown. In this case on the tapered side or" pane (hinged side of the door), the slide members d at the top and e at the bottom are both secured to the window frame and consequently move with the window.

At the rear edge of the door (lock side) at which the glass pane is at right angles, the slide member g at the bottom is secured to the window frame while at the top at the point at which the pane passes out of the door, the slide meniber f is secured to the door. The latter thus does not move with the window. By means of this arrangement of the slide members the greatest possible guide length is provided for the window for any desired position of the window. The slide members which are made oi somewhat elastic material are so fitted that the window is securely seated and chattering is prevented with certainty. The slide members are so secured that they can readily be exchanged after removal of the window.

The slide member d is connected to the window frame by means of a small riveted-on brass plate 7i. The slide members e and g are connected to the window frame by means or" a pin i which is riveted on the frame and engages in a corresponding hole in the slide member. The slide member f is secured to the door by means oi the small plate 7c which is bent down to a right angle. In order to enable the window to be withdrawn from above, it is suiiicient to unscrew the plate 1c and to unship the arms of the crank apparatus (not shown).

What I claim is:

l. A guiding arrangement for sliding windows having a straightedge and a bent-over edge etitending in part in the guiding direction, said guiding means comprising a relatively stationary frame from which the window can be partly pushed out, a guiding piece for guiding the straight edgecf the window, on t stationary trarne at that point at which the edge oi the window leaves the frame, a guiding piece on the straight edge of the window at the end thereof which is pushed down farthest into the frame so ico as to guide the straight edge of the Window by guiding means the distance apart of which increases as the window is pushed into the stationary frame and two guiding pieces on the bent-over edge of the windo-w for guiding this edge in the stationary frame at two points the distance apart of which remains fixed, one at the end thereof which is pushed down farthest into the frame and the other on the part of the said edge which extends in the guiding direction, at the point thereof which still remains within the stationary frame when the Window is pushed out to its farthest extent.

2. A sliding Window structure comprising the combination of a sliding window having a long edge and a short edge and a relatively stationary guiding frame for said Window from which the window can be partly pushed out, with two guiding pieces on the short edge of the window, one at the end thereof which is pushed farthest down into the frame and the other at the part of the said edge which still remains Within the frame when the window is pushed out to its farthest limit, a guiding piece on the long edge of the window at the end thereof which is pushed farthest into the frame and a guiding piece on the frame at the point thereof at which the long edge of the Window leaves the frame, whereby each of the said two edges of the window are supported in the frame at a1l times at two points spaced the maximum possible distance apart.
