FIELD OF THE INVENTION The present invention relates to a locking device.

[0002]

2. Description of the Related Art A locking device used for windows or doors is known. Usually, the locking device comprises a catching device, which can be engaged with one panel or frame of the entrance, for example by being fixed and moving on the door. The capture device is engageable with a retaining device mounted on the other panel or frame of the inlet in a corresponding position, and is engaged when the inlet is in the closed position. Perhaps the best known locking device is a metal locking device attached to the window frame, in which the capture device pivots around a post in the base,
The base is fixed to one window frame. The catcher slides under the catcher, which is typically a metal flange, and engages the retainer when the catcher and the retainer are placed in parallel with each other.
As a result, the window is closed and locked. When the capture device is moved in the opposite direction and unlocked, the window can be opened.

The locking device also comprises a catching device which is biased by a spring or other means which actuates the catching device in the locking direction relative to the holding device. This allows the catching device and the holding device to automatically engage when the window or door is strongly closed.
It is not necessary for the capture device to be manually placed in the flange of the holding device.

The present invention is a novel locking device having a biased capture device as described above, which when applied to a straight sliding door or window causes the door or window to slide and close. The capture device then automatically engages the retention device. Further, the present invention comprises a locking device that is easily unlocked by manually applying a stress to one point of the capturing device, the stress being applied in the direction opposite to the direction of the biasing force,
As a result, the catching device is released from its locked position relative to the holding device so that the door or window can be slid open.

Has a side wall and a back wall extending from a flexible lower plate, the lower plate having a capture device. This locking device is installed in the opening,
The opening is positioned so that the lower plate extends below the edge of the door and above the edge of the adjacent panel to secure the door and panel together.

The present invention is a novel locking device used for sliding glass doors, which has a simple structure and a manufacturing method. The locking device according to the invention is easy to operate and does not require a biased pin connection between the capture device and the housing. The easy exertion of transverse stresses on the elastic part of the locking device causes the catching device itself to be moved outwards, so that the catching device no longer engages with the holding device, ie disengages from it. The locking device of the present invention is particularly useful for sliding windows in passenger cars and trucks.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1, a locking device assembly according to the present invention is shown in operational relationship with a door or window to which the locking device assembly is attached and which is slidable in a straight line. A general view of is shown. The catcher assembly 2 is secured to the door or window pane by a suitable bonding method and is aligned with the retainer assembly 3 mounted to the surrounding frame. The components are preferably made of plastic, but may be made of metal. When the door or window is moved in the direction indicated by arrow A, i.e. in the closing direction, the catcher assembly 2 approaches the retainer assembly 3 and then the catcher assembly 2 and the retainer assembly 3 are in the locked position, In other words, they are detachably coupled at the fastening position (described later).

Referring to FIG. 2, there is shown a side view of the capture device assembly 2 of the present invention mounted on a sliding glass window or door 5. The capture device assembly 2 consists of a housing 4 mounted directly on the surface of a glass plate or panel by a substrate 6 and a capture device 8 essentially consisting of a single piece with four actuating elements. Spring means (not shown in FIG. 2) operate in the housing 4 as will be described below. The pushbutton part 10, which is integrally formed with and cooperates with the spring means, projects from the opening 12 in the housing and is actuated by the stress in the direction of arrow B.

The capture device 8 is pushed from the push button 10 to the tongue 1
6, a pointed lip 1 for actual engagement with the retainer assembly 3 for retaining the door or window in the locked position.
Terminate at 8. The lip 18 projects downwardly from the tongue 16 and is spaced a sufficient distance x from the base plate 6 of the housing 4 so that it can be engaged with the holding device 3 assembly.

The fixed holding device assembly 3 of the locking device according to the invention is also shown in FIG. The holding device assembly 3 includes a glass window or door panel 20, a frame 22, a rubber U-shaped gasket 24, and an L-shaped holding device 26. When the door or window is moved (in the direction of arrow A in FIG. 1) to close the sliding door or window as described in detail and briefly with reference to FIG. 1, the pointed lip 18 is U-shaped. It travels over the gasket 24 and then mechanically engages the retainer assembly 3 to secure and lock the door or window 5 to the frame 22 as shown in FIG.

Although an exploded view of the capture device assembly 2 is shown in FIG. 4, the capture device assembly 2 comprises three elements: a housing 4, a capture device 8 and a substrate 6. The capture device 8 is housed in the opening 12 of the housing 4 such that the spring means 28 contacts and is pressed against the inside of the back wall 30 of the housing 4. A pivot 32 is integrally formed with the spring means 28, and the pivot 32 is movably engaged with the U-shaped journal 34 of the base plate 6 by a pin or pivoting member 36. When assembled, the spring means 28 contact the inside of the back wall 30 to provide a stress that allows the spring means 28 to be biased about the pivot 32 and the journal 34.

FIG. 5 shows a side cross-sectional view of the capture device assembly 2 with the elements of FIG. 4 assembled together. Capture device 8
Are housed in a housing 4, which is attached to a door or window by a substrate 6. The capture device 8 is connected to the housing 4 by a pivot 32,
Are connected or inserted into the U-shaped journal 34.

The catcher assembly 2 and the retainer device 3 are joined side-by-side with each other so that when the door or window is closed, as shown in FIG. 5, a spring means 28 with a flange or lever is provided on the housing 4. Back wall 30
To contact. This point of contact provides a spring to bias the tongue 16 and lip 18 downward (in the direction of arrow C) toward the plane containing the door or window surface. When the catcher assembly 2 and the retainer assembly 3 are brought close together and engaged, the catcher 8 is positioned in the engaged position. When the catcher 8 is brought into the engaged position and the door or window is closed, the catcher 8 is provided with spring means 28.
It is held in the engagement position, in other words, in the locked position by the urging force of. This biasing force maintains the capture device 8 parallel to the door or window surface even when the capture device assembly 2 and the retainer assembly 3 are not engaged with each other. Therefore, the locking device comes to have the functions described later.

FIG. 6 shows a side cross-sectional view of the capture device assembly 2 similar to that of FIG. 5, but in FIG. The catcher assembly 2 is disengaged from the retainer assembly 3 and the catcher 8 is positioned in the disengaged position. The door or window 5 can be opened when the capture device 8 is positioned in the disengaged position. As can be seen from FIG. 6, when stress is applied to the push button 10 by, for example, the thumb or the index finger, a part of the pin 36 of the pivot portion 32 causes a portion of the journal 3 in the substrate 6 to be exposed.
4, so that the capture device 8 is U
It rotates about the letter-shaped journal 34 in the clockwise direction (direction of arrow E). The stress on the push button 10 actuated by hand must be sufficient to overcome the downward (i.e. in the direction of arrow C in FIG. 5) biasing force on the capture device 8. When this stress (in the direction of arrow B in FIG. 2) acts, the capturing device 8 pivots in the clockwise direction (in the direction of arrow E) and the capturing device 8 moves upward (in the direction of arrow F), As a result, the capturing device 8 becomes the holding device 2.
6 disengages, i.e. no longer engages with the retaining device 26.

When assembled, the spring means 2 as shown in FIG.
8 presses the inside of the back wall 30 as indicated by the arrow G, so that the spring means 28 exert a lateral biasing force which causes the pointed lip 18 to be directed downwards as indicated by the arrow C.
This is because the lateral stress (arrow G) is converted into the vertical stress (arrow C) at the location where the pivot portion 32 and the journal 34 are rotatably connected.

Referring to FIG. 6, a lateral stress (arrow D) acts on the push button 10 against the urging force of the spring means 28, and this stress causes the lip 18 to rise vertically (arrow F). ), So that the catching device 8 does not engage the holding device 26, i.e. disengages, so that the door or window can be moved. During the closing of a door or window, lateral stresses (arrow H in FIG. 5) act on the pointed lip 18, that is to say the holding device 26 has an inclined lip 1.
As it moves along the inclined front end 38 of the lip 18 under stress from 8, the catching device 8 likewise moves upwards. In operation, such upward movement of the capture device 8 occurs during sliding of the door or window to the closed position, with the lip 18 first engaging the retaining device 26 and then along the front end 38 of the lip. It moves to reach the tip 40, at which time the spring means being compressed exerts a downward stress on the lip 18 to engage the retaining device 26, resulting in the engagement position. It is positioned and locked.

FIG. 7 shows a cross-sectional view of the capture device assembly 2 taken along line VII-VII of FIG. 5, which shows the geometry between the housing 4, the base plate 6, and the pivot 32 of the capture device 8. It shows a functional relationship. This arrangement allows the lateral stresses produced by the biasing of the spring means to be converted into longitudinal and downward stresses, so that the catching device 8 causes the catching device 8 to hold the door or window in the closed position. The assembly 3 can be engaged. With this arrangement, when the push button is manually applied with a stress against the spring biasing force, this stress is converted so that the capturing device moves upward in the longitudinal direction, so that the capturing device engages with the holding device. Will not do.

Referring again to FIG. 3, the capture device assembly 2
This operative relationship between the and the retainer assembly 3 can be seen when the door or window is in the closed position. When the door or window is slidably closed, the pointed lip 18 is U-shaped.
Although in contact with the V-shaped rubber gasket 24, the gasket 24 is curved due to its elastic properties and cannot overcome the biasing force of the spring means 28. However, the L-shaped holding device 26 is firmly attached to the glass plate or panel 20,
It is also a non-movable projection which the capture device 8 must move over. Once the catching device 8 and the holding device 26 come into contact, the stress exerted on the catching device 8 by the holding device 26 increases the elastic stress exerted on the spring means 28, while the pointed lip and tongue are directed upwards. (Arrow F in FIG. 6) is moved. The point of contact between the retaining device 26 and the capture device 8 moves along the beveled front end 38 of the lip 18 to move the lip 18 of the capture device.
Of the lip 18 as shown in FIG. 3 due to the downward stress acting on the lip 18 due to the elastic stress built up in the spring means.
Engages with the retaining device 26 and is thus locked. A U-shaped rubber gasket 24, which extends below the plane defined by the sliding door or window 5, engages in a curving manner due to its elastic properties, so that it is between the sliding door or window and the main frame of the glass or panel. To form a seal at the joint.

It will be appreciated that simple modifications can be made to the locking device disclosed herein. These changes need not be included in the embodiments described above, however, these changes are included within the spirit and scope of the invention as claimed.
