Description

  The present invention relates to an automatic push-up spring lock that is attached to sliding doors such as sashes and doors.

  Many conventional locking mechanisms for sliding doors such as sashes and doors use a circular flat taper cam (crescent). After closing the sliding door, the circular flat taper cam rotates by hand along the central axis. In many cases, the sliding door is locked by hand, and the circular flat taper cam is reversely rotated by hand to unlock and open the sliding door. The sliding door automatically opens and closes when the sliding door opens and closes. There was no simple, thin and simple automatic locking device for sliding doors.

  Also, as a lock mechanism that is used after being attached to sliding doors such as sashes and doors, there are those using leaf springs as described in Japanese Patent Publication Nos. 2004-232345 and 2004-347000. However, as well as the difficulties in physical strength, as in the case described above, the sliding doors are automatically locked in conjunction with closing the sliding doors such as sashes and doors. There was no strong and simple automatic lock for sliding doors.

Furthermore, the present invention is characterized in that the push-up spring, the substrate, and the fixing plate of the push-up spring stopper of the sliding door automatic push-up spring locking tool described above are bonded by an adhesive instead of welding.

  In the present invention, the push-up spring stopper of the sliding door automatic push-up spring lock is simply attached to the sliding door, and the reinforcing plate of the push-up spring stopper is pressed against the elastic force of the push-up spring so that the bent portion of the push-up spring is horizontal. Open the sliding door by unlocking the sliding door in the state, close the sliding door and restore the bent part of the push-up spring welded with the reinforcing plate to the bent state by the elasticity of the push-up spring, and weld it to the bent part of the push-up spring The edge portion of the reinforcing plate collides with the edge portion of the fixed plate and does not move so that the sliding door is automatically locked.

  In addition, the present invention provides a robust retrofit by simply inserting the insertion portion welded to one end of the push-up spring stopper substrate of the automatic push-up spring lock for sliding doors into the gap existing in the already installed sash. As described above, it automatically locks in conjunction with closing the sash.

  The automatic push-up spring locking device for sliding doors according to the present invention will be described by taking a normal sliding door as an example. As shown in FIGS. 1 and 2, the substrate 3 is welded to the back surface of the horizontal portion 2 of the push-up spring 1 bent at 5 to 45 degrees. Further, the fixing plate 4 is welded to the surface of the horizontal portion 2 of the push-up spring 1, and the reinforcing plate 6 is attached to the surface of the bent portion 5 of the push-up spring 1 with the fixed plate 4 to 0.1 to 0.5 mm. The push-up spring stopper 7 is formed by welding at intervals of.

  Normally, the bent portion 5 of the push-up spring 1 of the push-up spring stopper 7 is bent with elasticity as shown in FIG. 2, but the reinforcement plate 6 is resisted against elasticity by a human finger. 3, the bent portion 5 of the push-up spring 1 is pressed against the substrate 3 to be in a horizontal state, and when the person's finger is separated from the reinforcing plate 6, the push-up spring 1 is bent. The portion 5 is restored to a bent state by elasticity.

A hollow portion 9 is formed in a part of the fixing plate 4, and the bent portion 5 of the push-up spring 1 slightly smaller than the hollow portion 9 is loaded into the hollow portion 9, and the surface of the bent portion 5 is A slightly reduced reinforcing plate 6 is welded to the fixed plate 4 at an interval of 0.1 to 0.5 mm and loaded into the hollow portion 9 to increase the welding area of the fixed plate 4 to the push-up spring 1. Accordingly, the stopper 7 is formed so as to withstand the pressing force applied to the fixed plate when the sliding door is locked, and the reinforcing plate 6 is pressed against the elasticity with a human finger to be in a horizontal state. The finger is separated from the reinforcing plate 6 and the bent portion 5 of the push-up spring 1 is restored to the bent state by elasticity as in the case described above.

As shown in FIG. 5, the push-up spring stopper 7 is arranged so that the right edge portion 6 b of the reinforcing plate 6 welded to the bent portion 5 of the push-up spring 1 is close to the end side surface of one sliding door 8 b in the closed state. Further, the right edge portion 6b of the reinforcing plate 6 fixed to the surface of the other sliding door 8a with the substrate 3 of the push-up spring stopper 7 closed by an adhesive or a screw and welded to the bent portion 5 of the push-up spring 1 is used. One sliding door 8b is locked.

Further, as shown in FIG. 6, the push-up spring stopper 7 pushes the reinforcing plate 6 with a human hand so that the bent portion 5 of the push-up spring 1 is in a horizontal state against elasticity and locks one sliding door 8b. Then, the other sliding door 8a to which the reinforcing plate 6 and the bent portion 5 that are in the horizontal state are attached is moved to the right in the gap formed between the sliding door 8b and the sliding door is opened.

Next, when the other sliding door 8a in the opened state is moved leftward to close the other sliding door 8a, the bent portion 5 of the push-up spring 1 is automatically restored to the aforementioned bent state by elasticity. Then, the sliding door 8b is locked by the reinforcing plate 6.

As shown in FIG. 7, the push-up spring stopper 7 functions as a topper because the left edge portion 6 e of the reinforcing plate 6 welded to the bent portion 5 of the push-up spring 1 becomes the right edge portion 4 e of the fixed plate 4. This is to prevent the other sliding door 8a from moving due to a collision, and to lock the other sliding door 8a. The pushing spring 1 alone cannot prevent the other sliding door 8a from moving, and the pushing spring 1 is folded. The sliding door 8b cannot be locked.

  In order for the push-up spring stopper 7 to have a function as a topper and to have a margin for bending the reinforcing plate 6 welded to the bent portion 5 of the push-up spring 1, as shown in FIG. The distance K between the left edge portion 6e of the reinforcing plate 6 welded to the bent portion of the sliding door 8b and the right edge portion 4e of the fixed plate 4 welded to the substrate 3 needs to be kept within a certain range. 6 and the thickness of the fixed plate 4 are affected, but in the normal case, the reinforcing plate 6 and the fixed plate 4 are often 1.5 to 2.5 mm in thickness. In this case, This interval K is set to 0.1 to 0.5 mm.

  The push-up spring stopper 7 is attached to the other sliding door 8a (or the sliding door 8b) using a gap existing between the sliding door 8a and the one sliding door 8b, so that the thickness of the pushing-up spring 1 is 0.3-0. 6 mm, the thickness of the fixing plate 4 and the reinforcing plate 6 is 1.5 to 2.5 mm, the thickness of the substrate 3 is 1.2 to 2.3 mm, and the thickness of the push-up spring 1 exceeds 0.6 mm and is fixed. When the thickness of the plate 4 and the reinforcing plate 6 exceeds 2.5 mm and the thickness of the substrate 3 exceeds 2.3 mm, the push-up spring stopper 7 (the reinforcing plate 6 in the horizontal state, the bent portion 5 and the substrate 3) This increases the thickness of the slidable member, which impairs the slidability. Also, the thickness of the push-up spring 1 is less than 0.3 mm, the thickness of the fixing plate 4 and the reinforcing plate 6 is less than 1.5, and the thickness of the substrate 3. If the thickness is less than 1.2 mm, the thickness of the push-up spring stopper 7 is reduced, and the physical strength as the push-up spring stopper 7 is increased. Problem occurs.

  Further, the reason why the bending angle of the push-up spring 1 is set to 5 to 45 degrees is for the push-up spring stopper 7 to function as a topper, and when the bending angle is less than 5 degrees, the sliding door by the push-up spring stopper 7 is used. If the bending angle exceeds 45 degrees, the holding force of the push-up spring stopper 7 as a topper may be hindered. Preferably, the push-up spring 1 has a bending angle of 10 When the angle is set to -30 degrees, the locked state of the sliding door by the push-up spring stopper 7 can be more stably maintained, and the holding force of the push-up spring stopper 7 as a topper is improved.

  In the normal case, the push-up spring 1 is made of a stainless spring and a hardened steel spring, the length is 30 to 100 mm, the width is 10 to 30 mm, the fixing plate 4 and the reinforcing plate 6 are made of stainless steel, iron, etc. The length is 15 to 50 mm, the width is 8 to 30 mm, the substrate 3 is made of stainless steel, iron, or the like, the length is 35 to 120 mm, and the width is 10 to 30 mm.

As shown in FIG. 9, the push-up spring stopper 7 is welded with the insertion portion 10 at the tip of the substrate 3, and even if it is a sliding door, as shown in FIG. the gap 11 as shown is in the window frame portion of the other of the sliding door 8a, more robust substrate 3 by inserting the insertion portion 10 of the substrate 3 in the gap 11, Ru attached stably.

  In a normal case, the reinforcing plate 6 and the fixing plate 4 are welded to the push-up spring 1, and the push-up spring 1 is welded to the substrate 3 to form the push-up spring stopper 7. The push-up spring stopper 7 is manufactured at low cost. May be bonded with an epoxy adhesive, for example, a one-component epoxy overheat-curing adhesive or a two-component epoxy room-temperature curing adhesive (Scotch Weld (manufactured by Sumitomo 3M Limited)) instead of welding.
