Window half-open fixing mechanism

Abstract

To provide a half-open window fixing mechanism capable of maintaining a half-open state while preventing the intrusion of suspicious persons in a glass sliding window without an outer lattice. [Solution] The window half-open fixing mechanism 1 is composed of two suction cups 10 with suction levers and a convex-shaped structure 20. One of the two suction cups with suction levers is attached to the house side of one of the two glass sliding doors, and the other of the two suction cups with suction levers is attached to the house side of the other of the two glass sliding doors. The suction cup with suction lever is attached to the structure so that it can rotate about an axis parallel to the surface of the suction cup, and can straddle the fixing lock near the center of the two glass sliding doors.

Description

[Technical field]

[0001] This invention relates to a window half-open fixing mechanism that fixes a window consisting of a glass sliding door in a partially open state to prevent unauthorized entry. [Background technology]

[0002] In windows that are made of sliding glass doors without exterior bars, when the sliding glass door is pulled open to let outside air in, a suspicious individual can pull the sliding door further from outside to widen the opening and get inside. To prevent this, various mechanisms are commercially available that prevent suspicious individuals from pulling the sliding glass door.

[0003] One of the above mechanisms is the burglary prevention lock, which is attached between the glass sliding door and the sliding door rail and fixed in place by applying force in the direction that pushes the gap between the glass sliding door and the sliding door rail apart, preventing the sliding door from being pulled further from the position where the burglary prevention lock is fixed.

[0004] Another mechanism is an auxiliary lock, which can be reshaped and is attached to the frame of one of the sliding glass doors by gluing, etc. The auxiliary lock does not normally restrict the movement of the sliding glass door, but when reshaped, it prevents the other sliding glass door from moving beyond the position of the auxiliary lock.

[0005] A similar type of auxiliary lock is the suction cup, which is attached to the glass surface of the outside sliding door on the inside side of the two sliding doors to restrict the movement of the sliding door. [Prior art documents] [Patent documents]

[0008] However, in the case of a burglarproof lock, a strong force is applied in the direction of spreading the gap between the glass sliding door and the sliding door rail, so there is a risk that the glass sliding door and the sliding door rail will become distorted if left in place for a long period of time. Also, in the case of an auxiliary lock, there is a problem in that the outer glass sliding door can be removed from the outside.

[0009] This invention was made in consideration of the above circumstances, and its purpose is to prevent intrusion from outside by maintaining a half-open state in a window consisting of a glass sliding door without an exterior grille without causing distortion in the glass sliding door and the sliding door rail. [Means for solving the problem]

[0010] In order to achieve the above-mentioned objective, the present invention has two suction cups with suction levers and a structure that connects the two suction cups with suction levers, and the structure is characterized in that each of the two suction cups with suction levers is attached so that they can rotate freely about an axis parallel to the glass sliding door. Effect of the Invention

[0011] According to this invention, the sliding door of a window is fixed in a half-open state to prevent intrusion from outside, and the sliding door is prevented from being removed from outside. Furthermore, no force is applied between the sliding door and the sliding door rail that make up the window, so there is no risk of distortion. [Brief description of the drawings]

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A window half-open fixing mechanism according to one embodiment of the present invention will be described with reference to the drawings. EXAMPLES

[0014] FIG. 1 is a top view of the window half-open fixing mechanism attached to a window, FIG. 2 is a front view of the window half-open fixing mechanism attached to a window, and FIG. 3 is another example of the structure. 1 and 2, a window half-open fixing mechanism 1 according to this embodiment is made up of two suction cups 10 with suction levers and a structure 20. Below, a description will be given of the window and the window half-open fixing mechanism 1 as viewed from above in FIG.

[0015] There is a window sandwiched between house wall surface 210 and house wall surface 220, and the window is composed of a sliding door rail 112 and an outdoor side glass sliding door 110 that moves on it, and a sliding door rail 122 and an indoor side glass sliding door 120 that moves on it. When the window is fully closed, a window fixing lock 121 and a window fixing lock fitting 111 can be fitted together to prevent the window from opening. The window fixing lock 121 and the window fixing lock fitting 111 are, for example, a crescent lock and a crescent lock fitting.

[0016] One of the two suction cups with suction levers is attached to the house side of one of the two sliding glass doors, and the other of the two suction cups with suction levers is attached to the house side of the other of the two sliding glass doors. The suction cup with suction lever is attached, for example, by lifting the suction lever 11 vertically to the suction surface and placing it on the sliding glass door, and then returning the suction lever 11 to a direction parallel to the suction surface. By lifting the suction lever 11 vertically and then returning it to a parallel direction, a space that is cut off from the atmosphere is created between the suction surface and the glass surface, and the suction cup with suction lever 10 is fixed by atmospheric pressure. A structure 20 is attached to one of the suction cups with suction levers 10 so that it can rotate around an axis parallel to the surface of the suction cup, and the other end of the structure 20 is attached to the other suction cup with suction lever 10 in the same structure.

[0017] The structure 20 is attached to the suction cup 10 with a suction lever so as to be rotatable around an axis parallel to the surface of the suction cup, and by having a convex shape, it can straddle the window frame on which the crescent lock 121 of the indoor side glass sliding door 120 is provided. The material of the structure 20 is not limited, but possible materials include flexible metal and flexible hard synthetic resin.

[0018] The suction cup 10 with a suction lever is attached when the window is half-opened by opening width A, and the opening width A is set to an extent that allows exchange of indoor air with outside air and makes it difficult for outside air to enter.

[0019] 2 shows a front view of the outdoor side sliding glass door 110 when it has been pulled out the length of opening width A and fixed by the window half-open fixing mechanism 1. The suction cup 10 with a suction lever fixed to the outdoor side sliding glass door 110 and the suction cup 10 with a suction lever fixed to the indoor side sliding glass door 120 are connected by a structural body 20. The crescent lock and the metal fittings for the crescent lock, etc. are straddled by the structural body 20 and therefore cannot be seen from the front.

[0020] Since the outdoor side sliding glass door 110 is connected to the indoor side sliding glass door 120 by a half-open fixing mechanism 1, even if the outdoor side sliding glass door 110 is removed from the sliding door rail 112 by a person trying to break into the house, if the opening width A is small, the suction lever 11 cannot be operated and the door cannot be completely removed.

[0021] As another example of the structure, a structure 21 is shown in Fig. 3. Although an example of a rectangular structure is shown in Fig. 1, ease of holding can be improved by narrowing the center while ensuring strength. Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and improvements and modifications may be made within the scope of the present invention. [Industrial Applicability]

[0022] It can be used not only on windows without exterior bars, but also on windows with exterior bars and windows locked with crescent locks to further increase the level of crime prevention. [Explanation of symbols]
