Description

[0001] The invention relates to a locking device for securing sliding windows in motor vehicles according to the independent claim.

[0002] For additional security of doors and windows, security bars are fixed and secured in the openings from the inside in an area between the walls of the windows and doors or the like.

[0003] Security bars are known that consist of two sliding parts which fit precisely over one another and are fixed between the jambs of windows and doors. Due to their telescopic design, the length of the security bars is variably adjustable and can be adapted to different window and door dimensions.

[0004] The profiles of the safety bar are round, square or rectangular in design to achieve the required stability.

[0005] The security bars have various fixing devices that are firmly attached to window or door frames or to the walls of the window and door recess. This installation is time-consuming and labor-intensive, and can lead to damage or weakening of the window and door reveals.

[0006] Safety bars with different fixing devices are known from documents DE 297 02 462 U1, G 94 12 262.8, DE 296 09 930 U1, DE 8902027 U1, DE 42 37 061 A1, GB 21119840 A.

[0007] Such a locking device for a window is known from DE 297 02 462 U1. The locking bar, designed as a hollow profile, is placed onto the projections of the bracket, which correspond to the cross-sections of the inner contour of the locking bar. To hold the locking bar between the walls of the window recess, the brackets are screwed into the masonry near the window frame. During installation, the locking bar is secured against displacement by a locking device, in particular by locking pins.

[0008] From DE 8902027 U1, DE 94 12 262.8 and DE 29609930 U1, locking devices are known which have locking pins, in particular fastening screws, at their respective ends. These pins are connected to the locking bar and protrude at the respective ends. To hold the locking bar between the window recesses, receiving sleeves, in particular bores for the locking pins, are inserted into the walls next to the window frame. The locking pins are either flexibly connected to a compression spring or rigidly connected to the locking bar. During installation of the locking bar, the locking pins at the respective ends are guided into the receiving sleeves, in particular bores.

[0009] Furthermore, DE 42 37 061 A1 discloses a locking element proposed as a rod, which engages with its two end regions in opposing boundary surfaces in retaining elements, wherein at least one end region is provided with a thread and is screwably connected to a threaded opening in the retaining element.

[0010] A similar locking device is known from GB 21119840 A. It consists of a telescopic locking rod with end plates at its ends, which are hooked into the wall bracket from above. The wall bracket is firmly attached to the wall or window reveal and has a slotted guide opening into which the end plates are inserted from above.

[0011] For the secure fixing of locking bars between window and door recesses, locking devices are known whose retaining elements are firmly embedded in reveals, holes are drilled in reveals, or fixing devices are attached to the masonry with screws, anchor sleeves, or bolts. In all cases, the installation of the brackets damages and weakens the window and door frames, walls, and masonry, and the retaining devices are permanently mounted to the window and door frames, walls, and masonry.

[0012] The invention is therefore based on the objective of creating a safety device that can be used repeatedly and easily installed between window and door recesses in a time-saving manner, regardless of position, without a fixed holding device on jambs and walls.

[0013] This problem is solved by a safety bar having the features of claim 1. Advantageous further developments are the subject of dependent claims.

[0014] The invention comprises a locking device for securing sliding windows in motor vehicles. The locking device includes a first tube section and a second tube section, which are axially displaceable relative to each other and lockable in predetermined axial positions relative to each other. The first tube section and the second tube section each include a retaining element with an engagement section at their outer ends. The engagement section is designed to engage in a rail-shaped receptacle of a sliding window frame in order to secure the locking device therein. In this way, a locking device is provided that overcomes the disadvantages of the prior art.

[0015] The locking device is divided into two parts to adjust to the width and height of the window or door. The locking device consists of two parts that can be slid together. The profile is round, rectangular, or square, and inside the locking device is a compression spring that ensures stable tension between the window reveal or guide rail. The compression spring pushes the telescopic locking device apart and presses the outward-protruding ends into the window reveal or guide rail.

[0016] Furthermore, the telescopic locking device has a locking mechanism that prevents it from collapsing. This locking mechanism consists of a tube with a threaded bore and a screw. The outer tube has a longitudinally open guide groove in which the locking device is axially guided by the screw. Once the locking device is in its final position inside the window or door recess, the screw is tightened securely, clamping the outer tube to the inner tube and preventing the telescopic locking device from collapsing.

[0017] The guide groove provides axial guidance to the locking device in the longitudinal direction and prevents it from being rotated.

[0018] During assembly of the locking device, the screw is guided through the groove-shaped longitudinal opening on the outer tube and through the locking bore in the inner tube and screwed to the fixing device.

[0019] The screw in the locking hole secures the locking rod against being pushed together.

[0020] Advantageously, the engagement section has a thickness that corresponds to the thickness of a sliding window in motor vehicles.

[0021] Furthermore, the engagement section advantageously has a thickness (D) in the range of 1 mm to 10 mm, in particular 4 mm to 8 mm.

[0022] Furthermore, it is advantageous that the engagement section has a width (B) in the range of 1 mm to 50 mm, in particular 10 mm to 40 mm.

[0023] Preferably, the engagement section has a length (L) in the range of 1 mm to 50 mm, in particular 10 mm to 40 mm.

[0024] Preferably, the retaining element comprises a base leg and a clamping leg, the clamping leg comprising the engagement section. The locking device according to the invention is characterized by having retaining elements at both ends, which have an L-shaped form. Advantageously, the L-shaped retaining elements have axially outwardly projecting engagement sections that engage in the reveal of the windows and doors. The retaining elements can be made of steel, sheet metal, or plastic.

[0025] Furthermore, it is preferred that the first pipe section and the second pipe section are designed in such a way that they can be pushed into one another.

[0026] Advantageously, the locking device also includes a compression spring designed to clamp the first pipe section and the second pipe section against each other.

[0027] A compression spring block is attached to the compression spring, against which the compression spring is supported. The spring's tension energy is determined by the compression spring block; the longer the compression spring block, the greater the preload force of the locking device in its initial position.

[0028] The tube with the groove-shaped guide opening is pushed over the compression spring block, thereby closing the opening of the guide groove and preventing the locking device from becoming dirty.

[0029] An embodiment of the invention is described in more detail below with reference to schematic drawings.
