IMPLEMENTATION OF A USEFUL MODEL

The essence of the design of a small-sized household safe is a steel cylindrical body 1, at the bottom of which there is a hole 2 for fixing with an anchor bolt 3 to the wall array 4. Two protrusions 5 and 6 (limiter) are parallel to each other on the inside of the open part of the housing. The housing is closed by a lid 7 with a side 8, the diameter of which is less than the inner diameter of the housing. The protrusions inside the housing are made in the form of segments arranged parallel to each other, and the diameter of the lid flange is made smaller than the inner diameter of the housing. On the cover there is a cylinder lock 9 with a locking plate 10 freely entering the housing with minimal play to the stop. One plane 11 of the proximal protrusion 4 from the inside of the housing serves as a limiter for the rotation of the lid around its axis, and the other plane 12 serves as a limiter for the locking strip of the lock. A distant protrusion on the inside of the housing is a limiter for the position of the cover. The lid flange is made with a notch 13, restricting the rotation of the lid. On the cover there is an opening 14 for installing a lock, fixing the nut 15.

To increase the reliability of protection of the keyhole and the locking device from being unlocked by unauthorized persons, a code plate is installed on the cover using screws 16, comprising an annular housing 17 with a trapezoidal wall, in which a plate 18 with an ellipsoidal hole (not shown) made coaxially with the keyhole is installed, and a removable code mechanism 19 provided with a steering wheel 20. The connection of the removable code mechanism with the annular body is made in the form of a bayonet. (Fig. 4, 9, 10)

Non-removability is the ability of a safe to withstand forceful removal from an element of a supporting building structure without causing significant mechanical damage to the case, incompatible with the subsequent use of the product for its intended purpose.

In a brick wall (load-bearing building structure) in a residential building, it is necessary to install a small-sized household safe. Using a diamond drilling method, a blind cylindrical hole is made in the wall array 4 to the size of the housing 1 of the built-in safe, adjusted for the technological tolerance of the size. Used a home puncher and special crowns / augers (for example for sub-sockets). A pre-oriented steel cylindrical body 1 is inserted into the blind hole obtained as far as it will go. Alabaster, cement or liquid nails can be applied to the prepared hole, which additionally fix the safe body in the wall. A hole is drilled through a hole in the dead bottom of the wall array and into a hole 2 made at the bottom of the cylindrical body 1. An anchor bolt 3 is screwed into a hole made in the wall for reliable fixation of the safe. The open part of the cylindrical case 1 of the safe (part with a lid and a code plate) is made not protruding beyond the frontal plane of the wall (supporting building structure). (Fig. 1)

Use of the Safe is as follows.

Valuable items are placed in the safe case 1, the lid 7 is inserted from the end so that the lid flange 8 abuts against the distal ledge 6 of the case. Then the lid is rotated around its axis until the cutout 13 interacts on the lid rim with the plane 12 of the proximal protrusion 5 of the safe body. Turning the key of the cylinder lock 9, the locking plate 10 is rotated and rests on the plane 13 of the proximal protrusion 5 from the inside of the housing. The lock is closed. Next, install the removable code mechanism 20 in the annular body 17 of the lining. The connection of the removable code mechanism with the annular housing is made in the form of a bayonet mount. Wheel 21 sets the code. All this provides reliable protection of the safe from unauthorized opening.

If necessary, the only visible element of the safe - the code mechanism - is disguised as the interior of the home. In the embodiment shown in FIG. 5-10 (photo), a cover with a code pad recessed in the housing is considered.

The design of a small-sized household safe provides compactness and ease of use, the limited usable volume is compensated by the ease of installation, stealth, since the open part is made not protruding beyond the frontal plane of the wall, and cannot be removed and is reliably locked.

Industrial applicability.

The utility model can be easily made from modern materials based on existing technology and can be most effectively used in the manufacture of a small-sized household safe.
