Description

  The present invention relates to a door knob cover that is mounted so that the door knob cannot be operated.

  For example, a condominium renter guides a vacant room of a condominium if there is a person who wants to enter the room, and in that case, unlocks the door with a key to bring.

  Therefore, when there are many vacant rooms and the key is wrong, the lock cannot be unlocked, and when the key is taken out by another person, there is a problem that guidance to the vacant room cannot be performed.

  The present invention has been made in view of the above circumstances, and an object thereof is to allow a door key to be always kept in a safe storage state in a corresponding door portion.

  In this device, in a bottomed cylindrical door knob cover that is mounted so that the door knob cannot be operated, a key storage portion that stores a key of a door lock corresponding to the door knob is provided inside the cylindrical main body. .

  According to the said structure, the key of a door can be accommodated in the key accommodating part of a doorknob cover, Therefore The key to be used can always be kept near the corresponding door.

  In particular, a storage recess provided on the inner peripheral surface of the cylindrical main body with the key storage portion being opened and closed with the back side of the inner peripheral surface of the cylindrical main body as a fulcrum, and a lid that is closed and fitted over the upper portion of the storage concave The key is housed in the housing recess covered with the lid, and the key is stably housed in a predetermined position in the door knob cover. Further, the lid can be easily opened and closed by placing a finger on the front part of the lid, and when the lid is closed, the lid is stably placed at a position where it is fitted into the storage recess and covers the key.

  Furthermore, since the magnet plate is attached to the peripheral surface of the opening of the cylindrical main body, the iron door can be magnetized and held on the magnet plate surface. Further, when the door knob cover is placed on the article, the magnet plate has elasticity, so that no noise is generated and the article is not damaged.

  According to this device, the door key can be kept in the corresponding door portion in a safe storage state.

  External perspective view of an embodiment of a door knob cover of the present invention   Sectional drawing of embodiment of the doorknob cover of this invention   The perspective view which shows the internal structure of embodiment of the doorknob cover of this invention   The perspective view which shows the internal structure at the time of the cover body opening of embodiment of the doorknob cover of this invention   Sectional drawing at the time of lid opening of the embodiment of the door knob cover of this device

  FIG. 1 is an external perspective view of an embodiment of a door knob cover according to the present invention, and FIG. 2 is a sectional view thereof. The door knob cover 1 has an operating ring 3, three gripping levers 4, and a ring-shaped magnet plate 6 attached to the opening edge of the bottomed cylindrical main body 2, and a dial lock 7 attached to the upper part of the outer peripheral surface. Furthermore, a key storage portion 9 is provided inside the cylindrical main body 2.

    Three gripping levers 4 are mounted in the annular recess on the front surface of the annular ring 3, and the annular ring 3 is interlocked with the gripping lever 4 by the locking structure. The magnet braid 6 is made of synthetic rubber containing magnet powder, and its back surface is attached to the surface of the plate member 15 with an adhesive or double-sided tape.

  The door knob cover 1 displaces the grip levers 4 by rotating the annular ring 3, and grips the door knob rod portion protruding from the door knob to the door side by reducing the inner diameter formed by them. In this state, the door knob cover 1 can no longer be removed from the doorknob. In this way, even when the door lock is opened, the door is not opened because the door knob cannot be rotated. Since the door knob cover 1 has a magnet plate 6 attached, when the door knob cover 1 is attached to and removed from the door knob in an iron door, it can be held magnetically attached to the door surface by the magnet plate 6 surface. is there. Further, when the door knob cover 1 is placed on an article such as a clog box, the magnet plate 6 has elasticity so that no noise is generated and the article is prevented from being damaged.

  In the dial lock 7, the dial ring 26 is adjusted to the unlock number, and the operation shaft 24 is moved backward by the operation of the slide operation unit 27, whereby the distal end portion of the operation shaft 24 is detached from the annular ring 3. In this disengaged state, the annular ring 3 can be rotated, whereby each of the grip levers 4 is opened, whereby the door knob cover 1 is removed from the door knob.

  As shown in FIG. 3, the key storage portion 9 is configured by providing a lid 71 on a storage recess 70 provided in the lower portion of the inner peripheral surface of the cylindrical main body 2. The lid 71 is provided so as to be openable and closable with a pair of fulcrum portions 74 at the back of the inner peripheral surface of the cylindrical main body 2 as fulcrums, and is opened and closed as shown in FIGS. This is easily done by placing a finger on the front part 77 of 71. Further, the lateral width of the lid 71 is substantially equal to the lateral width of the storage recess 70, and the side portions 72 projecting downward are provided on both sides. It is stably placed at a position where it is fitted and covers the key 80. Thus, by providing the key storage part 9 in the door knob cover 1, the key 80 to be used can be kept near the corresponding door, and it becomes unnecessary to carry the key 80. In particular, the key 80 is housed in the housing recess 70 covered with the lid 71, so that the key 80 is stably housed in a predetermined position in the door knob cover 1.
