Description

    This is an imposition lock that can be attached to a heel with a narrow door.

First, the cross-sectional shape of the door toe side vertical fence of the fence door will be described with reference to FIG.
When the lock is attached to this bag, it can be attached normally if the dimension is within the effective depth (34), whether it is a digging lock or an imposition lock.

The case where the conventional digging lock is attached to a thin ridge will be described with reference to FIG.
In addition to drilling holes for the cylinder and thumb turn on the outside and inside surfaces of the casket, the door end surface also has a large vertical hole for the lock case, reducing the strength of the casket.

Conventionally, there is no lock that can be attached to a thin scissors, especially a lock case with a small depth, and it is necessary to scrape and attach to the center of the scissors as shown in FIG. 8B.
The heel cut to the door end and the middle bone has almost no equal strength as the heel and is bent from that part.
It is only the glass strength that prevents the bending.
The result is that the wrinkles that should reinforce the glass are protected by the glass.

  In the case of a thinner jar, the lock case goes deeper, and the glass in the glass groove may be scraped off and attached. In this case, not only does the strength of the wrinkles decrease, but glass processing becomes difficult.

The case where the conventional imposition lock is attached to a thin bag will be described with reference to FIG.
It is not necessary to scrape the door end of the coffin, but it is necessary to scrape the inner frame of the coffin and pass it through the cylinder. The result is that the strength of the heel is reduced by cutting the inner bone.

Whether it is a digging lock or an imposition lock, the dead bolt must have a certain length.
The length is the total length of the stroke of the dead bolt and the portion left in the lock case in order to maintain the strength against the destruction of the dead bolt when protruding. And it seems that the lock that can be attached to the thin bag was not made because of the combination of Dharma and the dead bolt that put in and out the dead bolt.
Japanese Patent Application No. 2003-197078

The problem is to make a cylinder lock with high security that can be installed from the inside and outside of the room without losing the strength of the thin wall.
It is a problem to realize that it is easy to install and easy to use.

In order not to reduce the strength of the heel, it is necessary not to scrape the door toe surface and the inside bone.
If you think so, you can not use the digging lock, it becomes an imposition lock.
In the conventional imposition lock structure, when it is attached to a thin scissors, the inner bone must also be shaved off.
The method of attaching without cutting the inner bone was considered as follows.

If the shaft is divided into a cylinder shaft and a thumb-turn shaft, and the shaft of the outdoor cylinder is arranged before the position of the thumb-turn shaft on the indoor side where the dead bolt is put in and out, it is not necessary to cut the inner bone in order to pass the cylinder.
The shaft of the cylinder and the shaft of the thumb turn are connected by a gear and linked.

By doing so, the stroke and required length of the dead bolt can be secured.
The thumb turn is also easier to operate at a position away from the frame, resulting in an easy-to-use lock.

The exterior door backset, which is the outer core of the cylinder assembled outside the door, is small, and the indoor backset, the thumbturn shaft core, is made larger, making it easy to install on a thin wall. You can make an imposition lock.

A state in which the imposition lock with the back set inside and outside is attached to a thin bag will be described with reference to FIGS.
The lock case (5) is attached to the interior side of the bag avoiding the doors (14) of the frame.
The cylinder (3) makes a circular hole in the outdoor side surface and the indoor side surface of the bag to penetrate the bag. The dead bolt (6) protrudes from the back of the door (14) of the frame or against the door and locks it. The strength of the heel does not decrease because it does not cut the door end face (7) and the middle bone (8).

In the conventional imposition lock, as shown in FIG. 9, even the middle bone (8) and glass (99) must be cut. A structure that allows the imposition lock of the invention to be attached without shaving the bone and glass will be described with reference to FIGS.
In the conventional imposition lock, the cylinder axis and the thumb turn axis are the same axis. The shaft position is inevitably required to be a distance from the front of the lock case due to the stroke and length of the dead bolt. For this reason, the cylinder is overlapped with the center bone and the position of the glass in a thin ridge.

The imposition lock of the invention separates the cylinder shaft and the thumb turn shaft, and moves only the cylinder shaft forward so that the cylinder can be attached without shaving the ribs or glass of the rod.
The structure is such that the cylinder and thumbturn shaft, which have been the same shaft in the past, are separated, and both shafts are connected by gears, so that the cylinder shaft is arranged in front of the thumbturn shaft.

Conventionally, there is a lock structure in which the cylinder shaft and thumb turn shaft are separated and connected by a gear. Nothing is seen forward in the direction.
That is, there is no change between the outdoor backset and the indoor backset.
The purpose of separating the conventional cylinder shaft and thumb-turn shaft is to reduce the protrusion of the cylinder from the door surface with a thin door. By changing the back set inside and outside with an imposition lock, It is not for attaching without scraping the door toe surface or the inside bone.
The conventional idea is to keep the back sets on both sides of the room constant even if the axes are separated.

An imposition lock according to claim 2 in which cylinders are provided on both indoor and outdoor sides will be described with reference to FIGS.
The cylinder on the indoor side may be assembled to the thumb turn shaft (46), but when it is assembled to the thumb turn shaft, the protrusion of the indoor cylinder from the lock case surface becomes large.
As a method of reducing the protrusion, if the inner cylinder dharma (51) is connected to the outer cylinder dharma (48) by a gear separately from the thumb turn shaft, the position of the inner cylinder can be arranged behind the position of the outer cylinder.
And as shown in FIG. 7, the protrusion of the cylinder from a lock case can be made small.

The imposition lock described in claim 2 utilizes the technology of connecting the inner and outer cylinder shafts of a Japanese Patent Application No. 2003-197078 double-sided cylinder imposition lock with a gear.
In Japanese Patent Application No. 2003-197078, the inner and outer backsets are the same except that the inner and outer cylinders are separated in the vertical direction.
The imposition lock according to claim 2 is not separated vertically but for the purpose of separating it horizontally.

Conventionally, a full-scale lock that can be mounted on a thin ridge like the imposition lock of the invention without reducing the strength of the ridge and can be operated from the inside and outside of the room has not been found. Therefore, as shown in FIGS. 8B and 9, the door tips and inner bones of the coffin were shaved, sometimes even glass, and the strength of the coffin was reduced.
Without the strength of the coffin, the coffin door cannot withstand the wind pressure and cannot withstand the side pressure on the door or glass. By using the imposition lock of the invention, it becomes possible to lock the door without reducing the strength of the heel even with a thin heel.

FIG. 5 shows a horizontal cross section of the door-end side gutter which is a part to which the lock is attached.
The case where the imposition lock of this invention is attached to this bag is demonstrated based on FIG.
In the conventional lock, the cylinder and thumbturn shafts are the same axis, so the thumbturn shaft position (1) is the cylinder shaft position, and the cylinder cannot be attached without shaving the ribs and glass.
If the thumb turn shaft position is provided at the cylinder shaft center position (2) in FIG. 2, the stroke of the dead bolt cannot be secured, and the bending strength and breaking strength of the dead bolt when the dead bolt is projected cannot be secured.

In the imposition lock of the invention, the outdoor backset (21) which is the axial center (2) of the outdoor cylinder is made shorter than the indoor backset (22) which is the axial center (1) of the indoor thumb turn. In order to attach the cylinder, it can be done without scraping the core and glass.
The indoor backset (22), which is the thumb turn shaft core (1), can also secure the required length, ensuring the dead-bolt stroke and the bending strength of the dead-bolt when the dead-bolt is projected and the required strength. Secured.

The conventional meaning of the backset will be described.
The backset is usually expressed as a digging lock, and refers to the distance from the lock front surface attached to the door end surface to the center of the cylinder, thumb turn and grip ball.
With imposition locks that are installed avoiding door-to-doors, the back-set is usually not expressed because the door-to-door dimensions are not constant. However, this time, the backset is also expressed on the imposition lock to express the contents of the invention.

    In any case, the conventional backset concept is common sense both indoors and outdoors. For this reason, the design specification sheet also specifies that the backset 76 mm is used. There is no conventional idea that the back set inside and outside is different, and such designation and instructions at the time of manufacturing the door can be made. In the present invention, a tab can be broken in order to realize a highly reliable lock that can be attached to a thin bag without reducing the strength of the bag.
