Pedal-Actuated Locking Device for Frameless Sliding Sashes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for frameless sliding sash arrangements are either not suitable for locking multiple sliding sashes with a single device or require inconvenient operation, leading to reduced comfort and increased production costs.
Innovation Solution
A locking device with a guide element, latch, and resilient locking plate that allows for ergonomic operation by using a sliding element to move between locking and unlocking positions, enabling a single device to secure multiple sliding sashes and reducing production costs through a simple mechanical design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple lock is used that can only be locked or unlocked by the operator in a crouched position, then the locking device is easy to manufacture and has good accessibility in the base area, but the user must kneel or bend down to operate the operating element, reducing ergonomic comfort
Solution Approach 1:
The patent replaces the traditional mechanical operating element that requires manual manipulation with a pedal-based actuation system. The pedal, when pressed, mechanically actuates the locking hook through a linkage mechanism, eliminating the need for the user to kneel or bend down to operate the lock directly. This substitution of the operating mechanism resolves the contradiction by maintaining manufacturing simplicity while significantly improving ergonomic operation.
2Reliability
If conventional locking devices are used to lock each sliding sash separately, then each sash can be secured individually, but the operating convenience is reduced and the cost of manufacturing increases
Solution Approach 1:
The patent implements a universal locking device that can secure multiple sliding sashes simultaneously through a single operating action. The locking hook, when actuated by the pedal, engages with multiple locking elements positioned at different locations along the sliding sash system. This multi-functional design allows one locking device to perform the function of multiple separate locks, thereby reducing device complexity and manufacturing costs while maintaining comprehensive locking reliability across all sashes.
3Reliability
If multiple separate locking devices are used for multiple sliding sashes, then each sash can be locked independently, but the manufacturing cost increases
Solution Approach 1:
The patent merges multiple locking functions into a single integrated locking device. The locking hook and multiple locking elements are combined in one assembly that can be actuated simultaneously through a single pedal operation. This consolidation reduces the total number of components that need to be manufactured and assembled, thereby lowering manufacturing costs while preserving the ability to lock each sliding sash independently through the unified mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The locking device allows for easy, ergonomic operation of frameless sliding sash arrangements with multiple sliding sashes using a single locking device, enhancing usability and reducing manufacturing costs while maintaining an aesthetic appearance.
Implementation Method 1
a resilient locking plate (12) connected to the latch (10), wherein the locking plate (12) has a locking element (15) at an end facing away from the latch (10), wherein a locking element (15) is formed on a side of the locking plate (12) associated with the guide element (9), wherein a bending element (16) is formed on a side of the guide element (9) associated with the locking plate (12), wherein the guide element (9) and the latch (10) are arranged relative to one another in such a way that upon actuation of the sliding element (11), the locking element (15) is guided along the bending element (16), so that the first latching element (13) can be brought into an unlocking position or a locking position by bending the locking plate (12)

AI summary
A locking device (1, 1', 1") for a door or window sliding system is shown and described, comprising a first and a second locking element (7, 7', 8, 8"), wherein the first locking element (7, 7') can be attached to a first sliding sash profile element (4) and wherein the second locking element (8, 8") can be attached to a fixed object (3) or to a second sliding sash profile element (26"), and wherein both locking elements (7, 7', 8, 8") form a lockable unit. According to the invention, for burglar-resistant locking of a frameless sliding sash arrangement with multiple sliding sashes, the first locking element (7, 7') comprises a guide element (9) attachable to the first sliding sash profile element (4), a bolt (10), a sliding element (11, 11') connected to the bolt (10), and a [missing element] connected to the bolt. (10) has a connected spring-loaded locking plate (12),wherein the locking plate (12) has a first detent element at an end facing away from the bolt (10), wherein a locking element (15) is formed on a side of the locking plate (12) associated with the guide element (9), wherein a bending element (16) is formed on a side of the guide element (9) associated with the locking plate (12), wherein the second locking element (8, 8") has a second detent element corresponding to the first detent element for forming a detent connection, wherein the guide element (9) and the bolt (10) are arranged relative to each other such that when the sliding element (11, 11') is actuated, the locking element (15) is guided along the bending element (16) so that the first detent element can be brought into an unlocked or locked position by bending the locking plate (12).
