Assistive device for attaching and detaching sliding glass doors in buildings

Abstract

This invention provides an assistive device for attaching and detaching sliding glass doors in buildings, which allows for the safe lifting and removal of the inner glass door during repairs. [Solution] The locking clamp 1, which is integrated with the chain 7, is used to clamp the rail of the upper frame of the sliding window. The J-shaped fitting 3 is inserted from the left under the bottom frame of the outer glass door 2 and hooked in place. Then, the split groove of the lever handle 8 is hooked onto the chain, and the side of the lever handle 8 opposite to the split groove is lifted up. This creates a gap 4, and to hold this gap, the hook-shaped metal 12 of the chain 11 from above is hooked onto the chain 7. By holding the gap 4 in place, the outer glass door can be lightly pushed outwards by hand, creating another gap between it and the bottom frame. A spacer can then be inserted into this gap, maintaining the other gap and allowing the inner glass door 15 to be easily attached and detached.

Description

Technical Field

[0001] [In terms of content, it is as described in [Claim 1]. That is to lift the J-shaped fitting (3), hook it on the chain (7) that has been lowered and raised, and create a gap (4) between the lower frame and the lower rail. There are methods such as using screws, mini chain blocks, pulleys and ropes, etc. Among various attempts, the most practical method is to hook the lever handle (8) on the lowered chain (7), and by using the principle of the lever, lift the outer glass door (2) to create a gap (4) between the lower frame and the lower rail. Once the gap (4) is created, the outer glass door (2) floats and hangs in the air. Then, gently push the outer glass door (2) outward by hand to create a gap (5) between the lower frame and the lower sash, insert the spacer (6), and hold the gap (5), and the preparation is complete. Here, the lever handle (8) will be explained in detail. The lever handle (8) is made of thick plate metal or the like. The left end is bent into a T shape and a split groove (9) is processed. Ordinarily, one would want to sharpen the tip and insert it into the ellipse of the chain (7). However, when replacing with a new glass and performing the hanging operation for restoration, there is a risk that the sharp tip will damage the new glass. Therefore, a protective measure is provided at the T-shaped tip of the lever handle (8) with a soft material such as rubber to a width that can be protected. Next, place the split groove (9) of the lever handle (8) on the outside of the ellipse of the chain (7). Next, attach a chain (10) from the lower surface to the lower surface about 3 cm from the left tip, and its tip is attached to the J-shaped fitting (3). Near the right end of the lever handle (8) with a total length of about 15 cm, attach a chain (11) from the upper surface, and its tip is made into a fish-hook-shaped fitting (12). The lever handle (8) has a simple structure as described above, and can perform fine adjustment of force by the principle of the lever, and is a very easy-to-use structure.]

Summary of the Invention

[0002]

Problems to be Solved by the Invention

[0003] [When repairing broken glass, many windows have a structure where the inner glass door (15) cannot be removed unless the outer glass door (2) of a sliding door is removed first. On the first floor, this is not a problem as it can be reached from outside the window. However, on the second floor and above, it is not possible to reach, so the outer glass door (2) must be brought in from inside the room first. However, the inner glass door (15) gets in the way, making it impossible to reach with both hands, and bringing the outer glass door (2) into the room first in this state is an extremely dangerous task with the risk of it falling. In the case of large and heavy glass doors, there is a risk of it falling even with two people working. This invention solves this problem by lifting the glass to create a gap (4) to gap (5), and then holding the gap (5) with a spacer (6).] [Effects of the Invention]

[0004] [Because a gap (5) has been created, the inner glass door (15) can be safely lifted with both hands and dropped into the gap (5), causing it to detach from the frame and be brought into the room without any obstacles. Next, the outer glass door (2) can be placed on the bottom rail in the reverse order, without any obstacles, It can be safely brought indoors with both hands. Even on windy days, when the outer glass door (2) is lifted, the top is securely engaged with the upper rail. The bottom has a spacer (6) made by bending thick wire, the left end of which is inserted into a pipe attached to the back of the J-shaped fitting (3), and the right end is bent to hook onto the bottom rail. As a result, it is very stable even in strong winds. Setting up this device takes only about a minute and is hassle-free, and if you make the chain (7) to a length of, for example, 2.5m, It can accommodate almost all glass doors up to that size. Furthermore, when stored, it's small enough to fit in a lunchbox, so storage is not a problem. This solves the long-standing problems faced by glass repair companies, window frame repair companies, house cleaning companies, etc. [Other remarks]

[0005] [To prevent losing the spacer (6), tie it to the J-shaped metal fitting (3) with a string or something similar.] [Prepare a detachable S-shaped bracket (13) to attach near the J-shaped bracket (3). *Reasons will be explained later.* [By making the tip of the locking clamp (1) uneven as shown in Figure (7), the upper rail can be slightly bent, allowing the clamp to firmly grip the upper rail with minimal force.] [※The reason will be explained later. The S-shaped bracket (13) is not normally used. The device of this invention functions with just one set. However, rarely, there are window frames in which the outer glass door (2) cannot be removed except in the center of the window frame, and the inner glass door (15) gets in the way. In this case, using two sets of this device will solve the problem. The first set is used as before, on the left side of the outer glass door (2), as close to the center as possible. However, the inner glass door (15) gets in the way, and in terms of weight balance, the right side cannot be raised all the way. Normally, the J-shaped bracket (3) is used on the inside of the bottom frame, but with the second set, you might want to use it on the outside of the bottom frame. However, the chain (10) from below goes outwards and wraps around the vertical frame, so it becomes slanted, and there is a possibility that the J-shaped bracket (3) will slip and come off. For this reason, the J-shaped bracket (3) is not used, and the S-shaped bracket (13) is hooked at any position just above it. Next, on the side of the right vertical frame of the outer glass door (2), at the position of the lower rail relief section (14) Hook the S-shaped bracket (13) and lift it up in the same way as the first set. For the second set, you could also leave the J-shaped bracket (3) off from the start and attach the S-shaped bracket (13), but considering versatility, I think the S-shaped fitting (13) should be detachable. [Brief explanation of the drawing]

[0006] [Figure 1] This is a front view of a sliding window, with the frame omitted, and an illustrative diagram showing a simplified drawing of the product of this invention. [Figure 2] This is an illustrative diagram showing the relationship between the components of the device of this invention, with the inner glass door (15) omitted and only the upper and lower frame cross-sections shown, in the vicinity of the A-A cross-section in Figure 1 for clarity. [Figure 3]This is a close-up view showing how a gap (4) has formed between the bottom frame and the bottom rail, causing the outer glass door (2) to lift up. The outer glass door (2) is gently pushed outwards by hand to create a gap (5) of approximately 8 cm, and a spacer (6) is inserted into this gap (5) to hold it in place. [Figure 4] This is an illustrative diagram showing a lever handle (8) resting on the oval shape of the chain (7). [Figure 5] This is a diagram showing a lever handle (8) with a split groove (9) machined into the tip and parts attached. [Figure 6] This is a magnified view of the second set of this fixture, where the J-shaped fitting (3) is not used on the right side of the bottom frame of the outer glass door (2), and an S-shaped fitting (13) is attached at an arbitrary position above it, and then hooked onto the relief section (14) of the rail on the vertical frame. [Figure 7] This is a close-up view of the part where the locking clamp (1) has a textured surface at its tip and grips the upper rail. [Figure 8] The left end of a spacer (6), which is shaped like a bent wire, is inserted into a J-shaped metal fitting (3) with a pipe attached to the back, and the right end is placed on the cross-section of the lower frame.

Claims

[Claim 1] The rail on the upper frame of the sliding window is clamped with a locking clamp (1). A J-shaped fitting (3) is inserted from the left under the bottom frame of the outer glass door (2). The chain (7) hanging from the locking clamp (1) pulls up the J-shaped fitting (3), creating a gap (4) between the outer glass door (2) and the bottom rail, and holds it in place. Next, the outer glass door (2) is pushed outward by hand to create a gap (5) of about 8 cm between it and the bottom frame, and a spacer (6) is inserted into this gap (5) to hold the gap (5). This is an auxiliary device for attaching and detaching sliding glass doors in buildings.
