The Related Art

The invention relates to a lock system used to protect people from possible dangers. Said invention is comprised of a security lock that prevents opening and closing of particularly electrical appliances and any type of battery operated toys with direct intervention.

The Prior Art

Cables of any type of electrical appliance and all plugs within reach of children pose the risk of electric shock. Unplugging the cables of appliances which are not in use and using child lock for plugs reduce possible dangers significantly. However, when running electrical appliances, it is absolutely necessary to keep children under one's care. All types of electrical appliances such as washing machines, ovens, vacuum cleaners attract children's attention a lot. Particularly, they are curious about on-off and setting buttons on such appliances and they play with these buttons by pressing on them. This situation, on the other hand cause the appliances to do harm to children, by running. In addition, there is also the risk of fault in a short span of time as a result of continuous playing with them. With the purpose of protecting people and children in particular from this danger, cover systems hiding keypad are used. However, this cover system both can not be applied to all appliances' models and they can be opened by children. In the last years, particularly in white goods sector, child lock system has been used. In this system, buttons can be made mulfunctioned on condition that the keys on electrical appliances are kept pressed for some time or a button formed for the lock separately is pushed. Cancellation of this lock system also happens the same way. However, danger which is present for children can not be fully eliminated with the lock system. Because, during children's play with such buttons, cancellation of security lock easily is encountered. In addition, these security locks' being electronic also brings the risk of causing frequent faults and making mulfunctioned. Electrical appliances being in small size and portable, on the other hand, are stored in locations that are not within reach of children.

As in appliances used in homes, battery operated toys also constitute dangerous environment in cases of some uncontrolled use. Therefore, families want their children to play with these toys under their auspieces. And for this, what families are able to do is just to hide the toy in a location which children will not be able to discover it or is not within their reach. In this way, another security measure which in terms of not having a suitable storage area or posing the possibility of being discovered by child is not possible at all times.

In the prior art, the developments being the subject invention are provided below.

Detailed Description of the Invention

In this detailed description, the subject of the invention and its preferred embodiments are described only for a better understanding of the subject-matter and in a way not constituting any limiting effect.

The invention is a lock system (1) used in electric appliances or battery operated toys for the purpose of security. Said lock system (1) is comprised of

- a lower body (10) wherein electric switch (5) is located,

- a switch slide (12), located on said lower body (10), on which lock key (40) moves,

- a bearing body (20), connected with said lower body (10), wherein lock key (40) is positioned,

- a key slot (22) in said bearing body (20), providing splicing of lock key (40) into the body (20),

- a lock key (40) that activates electrical circuit by positioning inside said bearing body (20).

In Figure 1 , a disassembled view of the lock system (1) which is the subject of the invention is given. As seen in the figure, the lock system (1) is comprised of a lower body (10), an electric switch (5), a bearing body (20), a lock key (40) and a viewing portion (30).

In Figure 2 and 3, a detailed view of the lower body (10) is given. The lower body (10) is in a board of rectangular structure. In the centre thereof, there is an electric switch socket (11) that allows the electrical switch (5) to be positioned. At reciprocal edges of this socket (1 1) the lateral surfaces rising angular in vertical position to body (10) form the switch slide (12). The lock key (40) moves on the switch slide (12) within bearing body (20). Between slide (12) and body (10) edge, there are 2 connection tabs (13). These tabs (13) are in form of a outward protrusion from the lower part of the body (10). In addition, at the other reciprocal edges not containing tab (13), on the other hand, there are connection holes (15) in form of a gap wherein screws can be positioned. Connection of lock system (1) to the appliance or toy wherein it will be used is achieved by means of these connection holes (15) and tabs (13) thereof. At the edges of the body (10) where switch slide (12) is took placed, there are total 4 connection protrusion (14) outwards from the edge in a way to be 2 on each edge. These protrusions (14) provide connection of the lower body (10) and the bearing body (20) by splicing into the connection intrusion (28) located in the bearing body (20).

In Figure 4, 5 and 6, detailed views related with bearing body (20) are given. Located on the lower body (10), the bearing body (20) has the shape of a cover hiding electric switch (5). As seen in Figure 4, reciprocal side surfaces (27) constituting bearing body (20) are in an angular structure in a triangular shape, matching with the switch slide (12) of the lower body (10). Inwards from the edge constituting bottom part of this triangular structure, there are connection intrusions (28) in gap form. With passage of connection protrusion (14) of lower body (10) into these intrusions (28), connection between the lower body (10) and the bearing body (20) is achieved. On upper surface (21) of the bearing body (20), on the other hand, a key slot (22) in form of a gap is located, which allows splicing of lock key (40) into body (20). The Key slot (22) is comprised of guide protrusions (23) that determine passageway of lock key (40) into body (20). The guide protrusions (23) are lined in a way not to be aligned with one another on both reciprocal edges of the Key slot (22). In addition, these protrusions (23) also prevent free movement of lock key (40), within body (20) by positioning to guide Channel (43) located on the lock key (40). Apart from these protrusions (23), there exists guide . path (24) that provides movement of lock key (40), within body (20) in a fixed area. The guide path (24) is an embodiment, in the interior part of upper surface (21), in form of a protrusion that moves along in the same line with switch slide (12) into the body (20). Gap that remains between this guide path (24) and switch slide (12) forms the fixed area wherein lock key (40) moves within body (20). Switch slide (12) and guide path (24) on which lock key (40) moves during its movement in this fixed area pass into guide area (45) on the key (40). In the area that remains in the interior part of the protrusions forming the guide path (24), there are two lock protrusions (25) that provide lock key's (40) staying in fixed position inside body (20) by positioning to the lock slot is (44) located on the lock key (40). The lock protrusions (25) also prevent free movement of lock key (40) within body (20). In the centre of upper surface (21) of bearing body (20), a circular viewing hole (26) in form of gap is located. By means of this hole (26), upon positioning of lock key (40) within body (20), it can be checked whether illuminated on/off buton (6) that electric switch (5) owns is on or not, therefore whether electrical circuit is activated or not. In addition, a viewing portion (30) is used for the purpose of preventing any intervention from this hole (26) inwards. This part (30) is comprised of a glass-like transparent that allows viewing of interior of the body (20) and the same circular structure with viewing hole (26). By means of fixing protrusion (31) around the circular structure thereof, it is ensured that it remains fixed in alignment with upper surface (21) of body (20) by being connected to the viewing hole (26). Additionally, around the circular structure, there are fixing arms (32) in reciprocal position with one another. Support protrusions (33) in these arms (32) also support that viewing portion (30) remains fixed at the alignment wherein it is connected by positioning within body (20). In figure 7, 8 and 9, detailed views related with the viewing portion (30) are given.

In Figure 10, a front view of the lock key (40) is given. As seen in the figure, the lock key (40) is comprised of a grip (41) and a bearing section (42). In upper and lower surface of this bearing section (42), there are guide channels (43) in form of intrusion inwards from the surface. The number of these channels (43) varies according to the lock key's ( (40) and thus the lock system's (1) size. The guide channels (43) are in form of a way going along the bearing section (42). The guide protrusions (23) pass into the guide channels (43) during splice of lock key (40) from key slot (22) into body (20). Thus, it is ensured that the key (40) moves on a fixed course within the body (20). Additionally, at reciprocal edges of the bearing section (42), there are lock slots (44) in form of inward intrusions that remain in outer part of the channels (43) and allow positioning of the lock protrusions (25) located within body (20). At the edges acting on the switch slide (12) of the bearing section (42), there is a guide area (45), which looks like a channel, in form of an inward intrusion from the surface. This area (45) provides positioning of the switch slide (12) and the guide path (24) at the bearing section (42), during movement of the lock (40) within body (20). That the guide area (45) is in form of an intrusion prevents the key (40) from acting outside of the area formed by switch slide (12) and guide path (24). When lock key (40) is located within body (20), it has a viewing gap (46) that is in alignment with the viewing hole (26). Thus, with positioning of key (40) into body (20), it can be comfortably checked whether electrical circuit is activated or not.

In Figure 11 , a perspective view of the lock system (1) is given. With splicing of lock key (40) into bearing body (20), the lock protrusions (25) within body (20) get positioned into the lock slots (44) on the key (40). Thus, the key's (40) remaining in a fixed state within body (20) is provided. Additionally, by means of switch slide (12), guide path (24) within body (20), guide protrusions (23) in Key slot (22) and channels on the key (40), acting of the key (40) outside of a definite area within body (20) is prevented. The fact that side surfaces (27) of switch slide (12) and bearing body (20) are angular also narrows down within body (20) the field of action of key (40). Thus, because lock key (40) acts on switch slide (12) which forms a narrow and angular path within body (20), it activates the electrical circuit by exerting a force upon the on/off button (6). With activation of the circuit, it can be comfortably monitored by means of the transparent viewing portion (30) on body (20) whether the illuminated button (6) is on or not. When the process is complete, that is, when the electrical circuit need to be closed, the lock key (40) is gripped by the grip section (41), is held upwards and removed from inside of the body (20). The bearing body (20) also has a function of a cover that prevents access of children to on/off buttons (6) when the electrical circuit is in active or closed state. Activation of the electrical circuit upon positioning of the lock key (40) into body (20) also provides controlled operation of appliances and toys in a way that will not pose a danger.
