The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. These embodiments are simply provided so that this disclosure is thorough and complete and fully conveys the concept of the disclosure to those skilled in the art, and the present disclosure will only be defined by the appended claims. The same reference numerals refer to the same elements throughout the specification.

Furthermore, the embodiments described herein will be described with reference to a cross-sectional view and/or a schematic view, which is an ideal diagram of the present disclosure. Therefore, the form of the diagram may be modified by manufacturing technique and/or tolerance. Also, in each drawing illustrated in the present disclosure, each constituent element may have been illustrated to be slightly enlarged or reduced in view of the convenience of explanation. The same reference numerals refer to the same elements throughout the specification.

Hereinafter, the present disclosure will be described with reference to the drawings for explaining a razor handle assembly and a razor including the same according to an embodiment of the present disclosure.

FIG. 1is a plan view illustrating an appearance of a razor handle assembly according to an embodiment of the present disclosure.

As illustrated inFIG. 1, a razor handle assembly1according to an embodiment of the present disclosure includes a gripping part100and a connecting part200.

The gripping part100is a part which is grasped by the user's hand while the razor is being used, and the connecting part200is a part to which a replacement type cartridge (2, seeFIG. 3) is attached.

A housing110for supporting the connecting part200is provided at one end of the gripping part100. As illustrated inFIG. 1, the connecting part200is received in the housing110such that an operation button210and a cartridge holder270are exposed to the outside of the housing110.

The cartridge holder270is configured to be inserted into the cartridge2and coupled with the cartridge2, and the operation button210is configured to serve as a switch for separating the cartridge2from the gripping part100.

Hereinafter, the connecting part200of the razor handle assembly1according to an embodiment of the present disclosure will be described more specifically.

FIG. 2is an exploded perspective view of an end portion of the gripping part of the razor handle assembly and the connecting part according to an embodiment of the present disclosure.

As illustrated inFIG. 2, the housing110formed at the end portion of the gripping part100includes an open type installation space130through which an upper case230, a lower case290and the like of the connecting part200can be inserted from one end and installed. A block installing through-hole120to which the operation button support block220is coupled is formed on the upper surface of the housing110.

On the other hand, the connecting part200includes the operation button210, an operation button support block220, the upper case230, a pusher240, an elastic member251, a plunger260, a cartridge holder270, a holder clip280and the lower case290.

As illustrated inFIG. 2, the operation button210includes a base plate211, a protruding end212, and a first hook end213.

The operation button210is a button used when the user intends to separate the cartridge (2, seeFIG. 3) from the razor handle assembly1, and the user can separate the cartridge2by pushing the operation button210toward the cartridge2, while pressing the base plate211.

Generally, since the user uses the operation button210while pressing the base plate211using the thumb, the base plate211may have a circular shape approximately corresponding to an area of a first node of the thumb. However, the shape of the base plate211may be variously modified depending on a design, an ease of use, and the like.

The protruding end212is formed to protrude from the front end of the upper surface of the base plate211. The protruding end212supports the user's fingertip which moves the operation button210while pressing the base plate211so that the user can more easily move the operation button210.

The first hook end213is formed to protrude from the lower surface of the base plate211. The first hook end213is inserted into a first hook end coupling hole244of a pusher240to be described later to fix the operation button210to the pusher240. The operation button210is hooked to the pusher240with the operation button support block220, the upper surface of the housing110and the upper case230interposed therebetween.

The operation button support block220includes a block body221and a second hook end223.

The base plate211of the operation button210is seated on the upper surface of the block body221. As illustrated inFIG. 2, a slot222through which the first hook end213of the operation button210passes is formed to penetrate the block body221. The slot222is formed to extend by a certain length in one direction so that the first hook end213can move along the slot222, thereby guiding the movement distance and the direction of the operation button210.

On the other hand, the second hook end223is formed to protrude downward from the block body221. The second hook end223is inserted into a second hook end coupling hole232of the upper case230to fix the operation button support block220to the upper case230. Therefore, when the operation button210moves forward and backward, the operation button support block220maintains a fixed state.

As illustrated inFIG. 2, the upper case230includes an upper case body231and a third hook end234.

A second hook end coupling hole232into which the second hook end223of the operation button support block220is inserted is formed in the upper case body231. In the second hook end coupling hole232, a support bar233passing through the center of the second hook end coupling hole232is formed.

The support bar233supports a part of the lower end of the block body221so that the operation button support block220does not pass through the second hook end coupling hole232but is positioned on the upper surface of the upper case body231. Therefore, the operation button support block220may be fixed to the upper case230by the second hook end223, while being supported by the support bar233.

The third hook end234is formed to protrude downward from the outside of the upper case body231. The third hook end234is coupled to the outside of the lower case290to couple the upper case230and the lower case290.

The upper case230and the lower case290form a space in which a pusher240, an elastic member251, a plunger260and a holder clip280to be described later can be installed in the coupled state.

On the other hand, the pusher240is installed between the upper case230and the lower case290so as to be slidable in the front-rear direction. As illustrated inFIG. 2, the pusher240includes a push arm241, a support wall242, and a first hook end coupling hole244.

The push arm241is formed to extend from the support wall242toward the front (in the direction of the cartridge2). The first hook end coupling hole244is formed to pass through a plate extending from the support wall242toward the rear (in the direction of the gripping part100).

As described above, the first hook end213of the operation button210is inserted in the first hook end coupling hole244. Therefore, the pusher240is synchronously driven with the operation button210. That is, as the operation button210moves forward and backward, the pusher240moves integrally with the operation button210.

On the other hand, the plunger260is installed between the upper case230and the lower case290so as to be positioned on the upper portion of the push arm241. The elastic member251is interposed between the support wall242of the push arm241and the plunger260so that the pusher240and the plunger260are elastically supported.

A coupling protrusion (245, seeFIG. 5), to which one end of the elastic member251is fixedly installed, is formed on the support wall242. A coupling protrusion to which the other end of the elastic member251is fixedly installed may be formed at the rear end of the plunger260.

The plunger260is installed in the upper part of the push arm241so as to be slidable in the front-rear direction, is elastically supported by the elastic member251, is retracted by an external force, and moves forward again when the external force is removed. The plunger260elastically supports a fastening bar271of a cartridge holder270to be described later, by utilizing the elastic force of the elastic member251.

Further, the pusher240moves forward by the forward movement force of the operation button210, and when the external force is removed, the pusher240is retracted again by the elastic force of the elastic member251.

On the other hand, the holder clip280is fixed to the lower case290so as to be located between the pusher240and the lower case290.

As illustrated inFIG. 2, the holder clip280includes a first support rod281, a second support rod283, and a load connection bar285.

The first support rod281is formed to protrude forward from one side of the rod connection bar285by a certain distance, and the second support rod283is formed to protrude forward from the other side of the rod connection bar285by a certain distance. The first support rod281and the second support rod283are formed side by side so as to be spaced apart from each other by a predetermined distance.

A first insertion hole282is formed in the first support rod281, and a second insertion hole284is formed in the second support rod283.

As illustrated inFIG. 2, the cartridge holder270includes a fastening bar271, a first lug272and a second lug274.

The first lug272is formed to protrude from one side of the fastening bar271, and the second lug274is formed to protrude from the other side of the fastening bar271. The first lug272is provided with a first boss273formed to protrude toward the second lug274, and the second lug274is provided with a second boss275formed to protrude toward the first lug272.

The fastening bar271may be formed to be horizontally longer than the load connection bar285of the holder clip280so that the cartridge holder270is coupled to surround the outer side of the end portion of the holder clip280.

The first lug272comes into contact with the outer surface (the surface opposite to the surface facing the second support rod283) of the first support rod281of the holder clip280, and the first boss273is installed so as to be inserted into the first insertion hole282of the first support rod281.

The second lug274comes into contact with the outer surface (the surface opposite the surface facing the first support rod281) of the second support rod283of the holder clip280, and the second boss275is installed so as to be inserted into the second insertion hole284of the second support rod283.

Therefore, the cartridge holder270is pivotally supported by the holder clip280. Also, since the cartridge holder270is coupled to surround the front end of the holder clip280, the cartridge holder270can protect the holder clip280from external shock and the like.

As another embodiment, unlike the configuration illustrated inFIG. 2, a first insertion hole282instead of the first boss273is formed in the first lug272, a second insertion hole284instead of the second boss275is formed in the second lug274, a first boss273instead of the first insertion hole282is formed in the first support rod281, a second boss275instead of the second insertion hole284is formed in the second support rod283, and the cartridge holder270may be pivotally supported by the holder clip280.

On the other hand,FIG. 3is an exploded perspective view of a cartridge that is interchangeably coupled to the razor handle assembly according to an embodiment of the present disclosure.

As illustrated inFIG. 3, a cartridge2interchangeably coupled to the razor handle assembly1according to an embodiment of the present disclosure includes a plurality of blades22for cutting hair, and a cartridge frame21for supporting a plurality of blades22.

As illustrated inFIG. 3, the cartridge frame21has a roughly rectangular framework opened front and rear. Specifically, the cartridge frame21includes a pair of vertical frames (not illustrated) formed on each of left and right sides, and a pair of horizontal frames which connects the pair of side frames. The plurality of blades22is installed such that the cutting edge is exposed on the front surface of the cartridge frame21in a state in which both ends are supported by the side frames.

As illustrated inFIG. 3, one of the horizontal frames25of the cartridge frame21is provided with a latch26protruding toward the rear part of the cartridge2.

The latch26is formed to extend from the central portion of the horizontal frame25toward the open hole24bof the holder receiving portion24. The latch26can be formed to have an arc shape protruding to the rear part of the cartridge2, and has a structure in which the other end is elastically deformed by an external force while being supported by the horizontal frame25at one end.

Further, jig protrusions23aand23bcoupled to the holder receiving portion24are formed to protrude from both sides of the latch26.

AlthoughFIG. 3illustrates an example in which the latch26is formed in the horizontal frame25, according to the embodiment, the cartridge2has another support frame formed between the horizontal frames, and the latch26may be formed to protrude rearward from the support frame. In this case, the support frame may be formed substantially parallel to the horizontal frame.

The holder receiving portion24is a member which forms a holder receiving space (not illustrated) in which the cartridge holder270is received. A coupling structure for being coupled to the jig protrusions23aand23bis formed on both sides of the holder receiving portion24, an open hole24bis formed in the upper part thereof, and a holder insertion port24ainto which the cartridge holder270is inserted is formed in the lower part thereof. The open hole24band the holder insertion port24amay be spaces expanded from the holder receiving space.

The cartridge2according to the present embodiment is configured in which the holder receiving portion24and the cartridge frame21are separated from each other. Therefore, even when an external shock within a certain range is applied to the cartridge2, the holder receiving portion24may be deformed separately from the cartridge frame21and may absorb the external shock.

Therefore, compared with the case where the holder receiving portion24is integrally formed with the cartridge frame21, the possibility of breakage due to external shock is reduced. In addition, when an external shock of a certain level or more is applied, since the holder receiving portion24may be separated from the cartridge frame21, the possibility of breakage due to external shock is reduced as compared with the case where the holder receiving portion24is formed integrally with the cartridge frame21.

Since the holder receiving portion24of the cartridge2according to the present embodiment has a separate opening hole24bformed in addition to the holder insertion port24a, the holder receiving portion24can be more easily elastically deformed.

For convenience of explanation, the cartridge2illustrated inFIG. 3illustrates only an example of a cartridge coupled to the razor handle assembly1according to an embodiment of the present disclosure, and the razor handle assembly1according to an embodiment of the present disclosure may be coupled with more various forms of cartridges.

FIG. 4is a plan view illustrating a state in which the cartridge is coupled to the razor handle assembly according to an embodiment of the present disclosure, andFIG. 5is a schematic cross-sectional view taken along line AA ofFIG. 4.

As illustrated inFIGS. 4 and 5, in the razor handle assembly1according to an embodiment of the present disclosure, the cartridge holder270is inserted into the holder receiving portion24of the cartridge2and is coupled with the cartridge2.

As illustrated inFIG. 5, a locking claw271ain which the latch26is received is formed in a lower part of a fastening bar271of the cartridge holder270.

Since the other end of the latch26is elastically deformed by an external force, the end portion is pushed downward by the fastening bar271and elastically deformed during entry of the cartridge holder270into the holder receiving space of the cartridge2. After that, the end portion passes through the locking claw271a, and at the same time, the end portion is lifted upward and is engaged with the locking claw271a. As a result, the cartridge holder270is fixed in the cartridge2, and the cartridge2is coupled to the razor handle assembly1.

Since the razor according to the embodiment of the present disclosure has the cartridge coupling structure of the latch26and the locking claw271a, the razor can couple the cartridge2to the razor handle assembly1with the simplified cartridge coupling structure as compared to the conventional razor.

The plunger260and the support wall242of the pusher240are mutually elastically supported by the elastic member251. The plunger260elastically supports the fastening bar271by utilizing the elastic force of the elastic member251. The position at which the plunger260is located in a state in which no external force is applied may be at a home position of the plunger. In this state, the position of the cartridge holder270supported by the plunger260may be a home position of the cartridge holder.

The pusher240may be maximally retracted backward in the space in the upper case230and the lower case290by the elastic force of the elastic member251. The position at which the pusher240is located in the state in which no external force is applied may be a home position of the pusher, and the position of the operation button210when the pusher240is at the home position may be a home position of the operation button.

FIG. 5illustrates a state in which no external force is applied after the cartridge2is coupled to the razor handle assembly1. The pusher240, the operation button210, the plunger260, and the cartridge holder270are located at the home positions.

FIG. 6is a schematic cross-sectional view illustrating the driving state of the cartridge holder and the plunger according to pivoting of the cartridge.

As illustrated inFIG. 6, in a process in which a user uses a razor in which the cartridge2is coupled to the razor handle assembly1, the cartridge2may be used while pivoting about the razor handle assembly1by external force.

As the cartridge2pivots about the razor handle assembly1, the cartridge holder270fixed to the cartridge2also pivots integrally with the cartridge2. Further, the plunger260is retracted backward with pivoting of the cartridge holder270, and elastically supports the cartridge holder270. The retraction distance of the plunger260may vary depending on a shape of a part in which the plunger260and the fastening bar271make contact with each other, and a pivoting angle of the cartridge2.

Thereafter, when the external force which pivots the cartridge2to the state illustrated inFIG. 6is removed, the plunger260moves forward again due to the elastic force of the elastic member251, and restores the cartridge holder270to the home position (the state ofFIG. 5). That is, the elastic force of the elastic member251is used as a restoring force (first restoring force) by which the plunger260restores the cartridge holder270to the home position.

FIG. 7is a schematic diagram illustrating the driving state of the operation button and the pusher for cartridge separation.

As illustrated inFIG. 7, when intending to separate the cartridge2from the razor handle assembly1, the operation button210may be moved forward (in the direction of the cartridge) by a predetermined distance to separate the cartridge2from the razor handle assembly1.

Specifically, as the user moves the operation button210forward by a predetermined distance, the pusher240moves forward together with the operation button210.

As the pusher240moves forward, the push arm241moves forward to elastically deform the latch26and disengage the latch26from the locking claw271a.

As the latch26is disengaged from the locking claw271a, the cartridge holder270may enter a state of being detachable from the cartridge2to separate the cartridge2from the razor handle assembly1.

Thereafter, when the external force of moving the operation button210forward is removed, the pusher240moves backward again due to the elastic force of the elastic member251and moves the operation button210to a home position (the state illustrated inFIG. 5). That is, the elastic force of the elastic member251is used as a restoring force (second restoring force) for restoring the pusher240and the operation button210to the home position.

Since the razor according to the embodiment of the present disclosure can separate the cartridge2from the razor handle assembly1, simply by elastically deforming the latch26, using the pusher240, the force required to separate the cartridge is smaller than the conventional razor, and it is easy to remove the cartridge.
