Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for an electric lock battery that is attached to a door that is locked and unlocked by an electric lock.

[Conventional technology]

An electric lock that is attached to a door to lock and unlock the door can be supplied with electricity from a power source installed outside the door via electric wires, or powered by a battery installed in the door. A door equipped with the latter battery is aesthetically pleasing because there is no wiring from the outside, and also has the advantage of not causing electrical contact failures that tend to occur with external wiring.

As shown in the perspective view of the main part of the door equipped with a battery, a case C for accommodating the battery is provided adjacent to an escutcheon A provided on the surface of the door D, and the battery is housed in the case C. Using the battery as a power source, the door D is locked and unlocked by making a dead bolt F appear and retract from the front E provided on the end face of the door D.

The electric lock can be unlocked from the outdoor side by operating the PIN code, and from the indoor side by operating the thumb turn G provided on the escutcheon A on the indoor side, and by pressing the lever handle H provided on the escutsion A on the outdoor or indoor side. Rotate and insert the latch bolt J to open the door.

[The problem that the idea attempts to solve]

Case C accommodates a battery inside, so the height h protruding from the surface of door D is large.If the height and length of escutcheon A adjacent to case C are the same as that of case C, the design of escutcheon A will be the same as that of case C. There was a problem in that the escutcheon A became thick and large, spoiling the aesthetic appearance of the door.

The present invention has been made to solve this problem.

[Means to solve the problem]

In order to achieve the above object, in the door of the present invention, a case storage chamber is provided on the end face of the door, a case containing a battery is inserted into the case storage chamber,
An electric wire routed inside the door from an electric lock provided on the door was electrically connected to the battery inside the case.

[Effect]

Since the battery and the electric lock are electrically connected by wires routed inside the door, there is no case on the door surface to accommodate the battery, leaving only the escutcheon.

〔Example〕 Embodiments of the present invention will be described with reference to the drawings.

In the perspective view of FIG. 1, a case storage chamber 1 having a substantially rectangular space is formed on the end face of a door D, and contacts 2, 2 are installed on the back wall surface 1a of the case storage chamber 1. Electric wires 3, 3 routed from the electric lock K to the inside of the door are connected to 2.

A recess 4 having a constant depth is provided around the end surface of the door D of the case storage chamber 1.

On the other hand, there are multiple batteries B in case storage room 1.
The case 5 containing the case 5 is inserted, and the flange 6 provided on one side of the case 5 fits into the recess 4.

A hole 7 is provided in the flange 6 at each of the upper and lower positions, and a machine screw 8 inserted into the hole 7 is inserted into each of the upper and lower positions of the recess 4.
The case 5 is screwed into the female screw 9 provided at the
is fixed to the end face of door D.

The case 5 is provided with two contacts (not shown) that contact the battery B on the opposite surface of the flange 6, and these contacts contact the contact 2.

Thus, the electric lock K is electrically connected to the battery B via the electric wire 3 and the contact 2.

The case 5 fixed to the end face of the door D has the end face of the flange 6 substantially flush with the end face of the door D.
It does not hit the door frame when opening or closing.

Further, when the door D is closed, the view of the case 5 is blocked by the door frame, and only the escutcheon A is visible on the surface of the door D.

In the above embodiment, the case storage chamber 1 is locked with an electric lock K.
The case accommodating chamber 1 of the door D close to the electric lock K may be integrated with the electric lock K, and as shown in FIG.
may be provided.

[Effect of idea]

Since the present invention is configured as described above, it produces the effects described below.

(a) The battery case, which was conventionally attached adjacent to the escutcheon on the door surface, is now inserted into the edge of the door, making the overall appearance of the door more beautiful, and the escutcheon design no longer being restricted by the battery case. This made it possible to make the escutcheon thinner and smaller.

(b) Since it is inserted into the edge of the case door that houses the battery and cannot be seen from the outside, there is no problem in making the case large in terms of design.

Therefore, a large-capacity battery can now be used, which has the advantage of extending the life of the battery.

(c) When the door is closed, the case is covered by the door frame, so it is protected from malicious mischief such as removing the case.
