Description

[Detailed description of the invention] (Industrial application field) This invention is an invention related to an auxiliary lock for a sliding door in a building.

(Prior art) The auxiliary locks conventionally used include so-called push-button type auxiliary locks and push-out type auxiliary locks.
-There are things described in Public Utility Model Publication No. 14196, etc.

(Problems to be solved by the invention) However, the push button type has a complicated structure because it incorporates a spring, and requires adjustment with the mating receiving part, which requires cost and effort. This method requires a long actuating body to make the blocking surface sufficiently protrude into the door passage, so a long part is required to cut out the end face of the stile, which reduces the strength of the stile and prevents the stile from collapsing. This may cause problems with the sealing properties of the
The function of the sliding door after installation is disadvantageous. For example, in the case of the see-saw type invention described in JP-A No. 49-95799, although it is compact, the protruding dimension of the sliding door stop surface cannot be made very large, and the lock piece cannot be held inside the case. Since it uses the frictional force between the wall surface and the lock piece, there is a risk that it may become loose after many years of use, making operation uncertain. Naomi Kaisho 51-
The device described in Publication No. 14196 is provided with an elastic body with a stop that prevents the locking member from moving inadvertently, but is similar to the above-mentioned device in that the protruding dimension of the locking member is small. The purpose of the present invention is to provide an auxiliary lock for preventing the release of a sliding door made of a molded synthetic resin material, which has a sufficient protrusion dimension, is easy to operate, and can securely hold the protruding stopper for preventing release. It is about providing.

A gap corresponding to the thickness of the sandwiching portion 2a is formed.
Reference numeral 13 denotes an engagement groove recessed in the upper surface of the upper wall of the case part 10 to allow the case part 10 to be engaged with the engagement protrusion 6 of the profile 1; the first stop extends downward from the center of the lower end of the flange plate 9; The pivot piece 15 is a support shaft hole in which a retractable stopper 8, which will be described later, is supported by a support shaft 16. Incidentally, an appropriate gap may be provided in the peripheral wall of the case portion 10 in order to save material and the like. Next stopper 8
consists of a thick square or rectangular plate,
One side surface 8a serves as an auxiliary lock as an opening preventing surface 8a that comes into contact with the door frame (inner door frame in the case of a double sliding door) of the opened sliding door. The center of the lower part is cut out to provide a mounting space 8b for the pivot piece 14 of the case portion 10, and the pivot pieces 17 are bored horizontally through the support shaft hole 17a on both sides thereof. Reference numeral 18 denotes an elastic piece having a U-shaped cross section, which is formed from the lower side 8d around the notch 8c at the center of the upper end of the retractable stopper 8, and is either integrally formed during molding or made separately, and its base is fixed to the lower side 8d. An operating piece 19 is provided on the outer end of one free end 18a, and a locking portion 20 is provided on the back thereof. 20b is a space that is activated when the operating piece 19 is pushed down with a finger, 8e is a recess corresponding to the thickness of the flange plate 9 of the mounting body 7 provided on the back side of the retractable stopper 8, and 8f is a chamber of the mold material 1 on both sides thereof. This is the contact surface with the inner parallel side wall 2a. The modification of the retractable stopper 8 shown in FIG. 4 has an opening 8g instead of the notch 8c in FIG.
An elastic piece 18 with a U-shaped cross section whose base is fixed to the upper piece 8h integrally or separately is projected toward the locking hole 11 of the mounting body 7, and a locking member consisting of a hook portion 20c is attached to the elastic piece 18 on the fixed side. A stop portion 20 is provided, and an elastic piece 1 is provided.
An operation piece 19 is provided at the tip of the free end of the operation piece 8 in a protruding manner.

The mounting body 7 and the retractable stopper 8, which have the above-mentioned partial structures, are made of elastic, tough, and weather-resistant synthetic resin, such as polypropylene.
It is preferable to make it in one piece using a molding process such as injection molding from a resin material such as polyamide, polyester, or polyacetal. The piece 14 is integrally made of synthetic resin or metal material,
The case part 10 made of a separate synthetic resin or metal material may be joined by welding, welding, adhesion, etc., and the base of the metal elastic piece 18 is connected to the protrusion stopper 8 made of synthetic resin. It may also be attached to.

(Function) Although the embodiment of the present invention has the above partial structure,
The effect will be explained. First, the auxiliary lock K of the present invention is assembled by attaching the retractable stopper 8 to the pivot piece 14 at the bottom of the mounting body 7, which is made by integral molding using a synthetic resin material.
By fitting the mounting space 8b between the pivot pieces 17 on both sides of the lower part of the , aligning the support shaft holes 15 and 17a on both sides, and inserting the support shaft 16 through one piece of the support shaft hole 17a, the two become one body and the support Form lock K. Next, as an example of attaching this auxiliary lock K to a frame constituting a horizontal stile or crosspiece of a sliding door of a building, Figures 1 to 3.
To explain using the profile 1 of the lower stile of the sliding door shown in the figure, the protrusion stopper 8 of the auxiliary lock K is pressed against the mounting body 7, and the locking part 20 of the protrusion stopper 8 is attached to the flange plate 9 of the mounting body 7. Lower edge 9a of engagement opening 12
When the locking portion 20 is a locking protrusion 20a (see FIGS. 1 and 3), the elasticity of the elastic piece 18 itself is used, and when the locking portion 20 is a hook portion 20c (see FIG. 4) ) Push down the operating piece 19 to lock the locking portion 20 to the engaging portion 12a of the mounting body 7. In this state, the flange plate 9 of the mounting body 7 fits into the recess 8e of the retractable stopper 8. Next, insert the case part 10 of the mounting body 7 into the frame 1 through the opening 5 of the side stile, and insert the back side of the flange plate 9 into the indoor parallel side wall 2a of the frame 1.
7, and then keep it in contact with the mounting body 7.
When the entire body is moved to the left in FIG.
At the same time, the clamping part 2c on the side edge of the opening 5 of the mold member 1 is clamped, and the engaging groove 13 in the upper part of the case part 10 is clamped.
However, by engaging with the locking protrusion 6 of the profile 1, the auxiliary lock K can be reliably and fixedly attached to the profile 1. At that time, the contact surface 8f at both ends of the back surface of the retractable stopper 8
is in contact with the indoor parallel side wall 2a of the profile 1, similar to the back surface of the flange plate 9. When it is necessary to use the auxiliary lock K that has been installed as described above, push down the operating piece 19 with your fingertip to engage the engaging portion 12a of the mounting body 7 and the locking portion 20 of the retractable stopper 8. Since it comes off, when the retractable stopper 8 is pulled toward the front, the upper part of the retractable stopper 8 is largely tilted toward the passage of the sliding door about the support shaft 16. In this state, even if the indoor side door of the sliding door is opened, the end face of the sliding stile inside the door comes into contact with the release prevention surface 8a of the protruding/retracting stopper 8 and is prevented from opening any further. If it is necessary to open the door further, press the upper part of the retractable stopper 8 and insert the elastic piece 18 into the locking hole of the attachment piece 7 using the support shaft 16 as in the case of attaching the auxiliary lock K. 11, and the engaging portion 12a and the locking portion 20 of the protruding/retracting stopper 8 are engaged.

(Effects of the invention) The present invention, which has the above-mentioned structure and function, can be used with the release prevention surface of the protrusion stopper fully protruding into the door passage, so the door opening prevention operation is reliable, and the operation can be performed with one touch. You can do it with In addition, if the elastic piece of the retractable stopper is integrally molded from a synthetic resin material, there is no need for steel spring material that rusts easily when used in a humid place such as a bathroom, and there is no problem with durability. Since a link mechanism with a complicated structure is not used for the ejection and retraction of the ejection stopper 8, the number of parts is small, assembly man-hours are reduced, and the length is short enough to reduce costs. Engagement portion 12 between stop portion 20 and attachment piece 7
Since the engagement of a is released and the retractable stopper is pulled out, confirmation of the operation is highly realistic. others,
Since the operating piece 19 is attached to the elastic piece 18, it is easy to check the state of engagement between the locking part 20 and the engaging part 12a, and furthermore, when the elasticity of the elastic piece 18 deteriorates due to long-term use, it can be easily checked. Compared to steel springs etc. installed inside, the deterioration can be easily detected, and by releasing the pivot between the mounting piece 7 and the pivoting piece 14 and easily replacing each pivoting piece 17. , it is possible to update its functionality.
