5 Claims, 7 Drawing Figures 3187. 525 v SE 20? 2 CASE HAVING MAGNETIC LOCK MEANS FIELD OF THE INVENTION This invention relates in general to the construction of interengagable container parts and in particular to a new and useful case or container which is made up of telescopically interengagable top and bottom parts and which includes magnetic means for effecting latching and unlatching of the two parts.
DESCRIPTION OF THE PRIOR ART The present invention relates to the lock device of the lid of a container such as a pencil case. As a conventional container such as a pencil case has not been provided with a lock device, more or less expensive commodities can not be contained with safety. Recently some pencil cases have been provided with the lock device, but the mechanism is complex and expensive. The object of this invention is to offer a container such as a pencil case having the lock device which is simple in its mechanism. 1
Accordingly it is an object of the invention to provide an improved container having a novel means for latching and unlatching two interengagable container parts which includes a magnet which is positionable to attract the latch members to displace it either into a latching position or into an unlatched position, in accordance with the setting of the magnet and the latched parts.
A further object of the invention is to provide a container which includes a rectangular box shaped bottom part and similarly shaped upper part which is engagable over the bottom part and wherein the top part includes a depending latch member on each side which are eiigagable with respective receiving detents defined on the side walls of the bottom part when the two parts are telescopically interengaged and the container is closed, and wherein the top part includes a recess for receiving a magnet which when positioned in the recess will attract the latch members of the top part to move them out of engagement with the bottom latch part and detents.
A further object of the invention is to provide a case which is simple in design, rugged in construction and economical to manufacture.
For an understanding of the principles of the invention, reference is made to the following description of typical embodiments thereof as illustrated in the accompanying drawing.
BRIEF DESCRIPTION OF THE DRAWINGS In the Drawings:
FIG. 1 is a front top exploded perspective view of a case constructed in accordance with the invention;
FIG. 2 is a top side perspective view of the bottom portion of the case shown in FIG. 1;
FIG. 3 is a bottom side perspective view of the top portion of the case shown in FIG. 1 and with a portion thereof being broken away;
FIG. 4 is a section taken along the line A-A of FIG.
FIG. 5 is a section taken along the line AA of FIG. 1;
FIG. 6 is a section similar to FIG. 4 showing the magnetic device in the attracted position;
FIG. 7 is a view similar to FIG. 5 showing the magnetic device in position.
GENERAL DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings in particular, the invention embodied therein comprises a casing generally designated 10, which includes a lid or cover part 1 of rectangular box shaped form which telescopically engages over a bottom part of similar form.
In accordance with the invention the top part 1 includes a top wall with a recess or indentation 2 of rectangular form shaped to receive the bottom portion of a magnet holder 3 which includes a handle portion for lifting it into and out of the indentation or recess 2. The top wall of the top part 1 includes a hollow portion with cavities 4 and 4' on each side of the indentation 2 as shown in FIG. 4. The two cavities include latch means which are interengagable with detents 11 and 11 of the bottom 6 when the two parts are telescoped together. The latch means include hook shaped latch members 7 and 7 having horizontal portions which ride in the respective hollows 4 and 4' and depending portions which terminate in hooks 9 and 9' which engage into recesses or detents 11' and 11 respectively of the bottom part 10. When the latch parts 7 and 7 are in the operative position the hooks 9 and 9' will engage automatically into the detent holders 11 and 11. In accordance with a feature of the invention the entire latch part 7 and 7 is made of magnetically attractable material or it includes a magnetically attractable portion 5 and 5 respectively which ride in the hollow spaces 4 and 4 and which are biased into an operative position by springs 6 and 6' respectively. In the operative position shown in FIG. 4 the hooks engage into the detents 11' and 11 of the bottom part and hold the two parts together so that they may not be unlocked. However when the latches 7 and 7 are attracted by a magnetic field the hooks 9, 9 are moved out of engagement with the associated detents 11, 11'.
The example shown in the drawing consists of a case ofacoveriiig type mare of'fia'r'dsyn'fli'tic'r'sifi. In the example, the engagement or disengagement of the hooked projections (7) (7') and the connections (11) (11') can be discerned by the indication of the displaying areas (12) (12) provided to the outside of the magnetic pieces (5) (5) through the peep holes (13) (13') provided to the ceiling wall of the hollow indentations t In the present invention described above, by lightly pressing the lid (I) placed on the case proper (10) the hooks (9) (9') at the tip of the magnetic pieces (5) (5) are engaged with the connections (11) (11) to make it impossible to open the lid (1) due to the mechanism in which the magnetic pieces (5) (5') are forced into against the elasticity of the spring elements (6) (6) and then withdrawn to the former position when the jaws of the hooked projections (7) (7) engage with the protruded edges of the connections (11) (11'). On the other hand, when the magnetic device (3) is fixed into the indentation (2) the magnetic pieces (5) (5') are drawn near and the engagement between the hooks at the tip of the projections (7) (7) and the connections (11) (11) can be released.
As mentioned above, in the present invention relating to the case of a covering type the indentation (2) is formed on the surface of the ceiling wall of the lid (1) and the flat hollow indentations (4) (4') are formed on the both sides of said indentation (2) with which the magnetic device (3) is connected or disconnected, the magnetic pieces (5) (5) being provided to the hollow indentations (4) (4') so that the former can proceed to or recede from the indentation (2), the spring elements (6) (6') being provided so that the magnetic pieces (5) (5') can be withdrawn to the farther position, the hooked projections (7) ('7') turning outward being provided to the underside of said magnetic pieces (5) (5 and protruded to the underside of the lid (1) through the holes (8) (8'), and the hooks (9) (9') at the tip of the projection (7) (7) are made to engage with the connections (11) (11) provided to the case proper so that it can properly be said that the present invention has excellent merits in the easy and exact engagement and disengagement of the lid (1) as described in the above example, especially in the exact engagement due to the elasticity of the spring elements (6) (6') provided to the magnetic pieces (5) (5').
