Patent Description:
With development of the economy and the society, more and more abundant consumables are provided for people to enrich people's material live, and then improve people's living standards. Razors are one of these consumables.

At present, the existing razor can be mainly divided into an electric razor and a manual razor. For the manual razor, it cuts the beard by a razor head using the power provided by the user, so as to finish shaving. Therefore, compared with the electric razor, the manual razor is more environment-friendly and has an increasing share of the market.

A razor is disclosed in <CIT>. An interconnect structure <NUM> has an engagement cavity <NUM> matched with the engagement portion <NUM> of the handle <NUM>. The engagement cavity <NUM> has the same inclination as the engagement portion <NUM>,. , and the engagement cavity <NUM> is provided with an engagement member <NUM> connected with an operating member <NUM>, one end of the engagement member <NUM> extends out of the engagement portion <NUM>,. , an inner wall of the engagement cavity <NUM> is opened with a engagement hole <NUM> engaged with the engagement member <NUM> (see the first paragraph on page <NUM> of the specification, and <FIG> and <FIG>). Thus, left and right ends of the engagement member <NUM> are engaged with the corresponding engagement hole <NUM> respectively, thereby engaging the interconnect structure <NUM> with the handle <NUM>.

Thus, the left end of the engagement member <NUM> is engaged with the left engagement hole <NUM> and the right end of the engagement member <NUM> is engaged with the right engagement hole <NUM>, so as to realize the connection between the handle <NUM> and the interconnect structure <NUM>. That is, the connection between the handle <NUM> and the interconnect structure <NUM> is realized by a multi-point engagement on the left and right sides, so the connection structure between the handle and the interconnect structure is complicated.

Moreover, for the razor disclosed in <CIT>, the razor head <NUM> also needs to rely on the pushing structure arranged on the handle <NUM> and the spring provided on the pushing structure and the handle <NUM> to make the razor head <NUM> to reliably pivot around the interconnect structure <NUM> relative to the handle <NUM>. Therefore, the pushing structure and the spring further cause the existing razor to have the defect of complicated assembly and structure. European patent <CIT> discloses a razor includes a connector <NUM> includes a connector body 25a, which is substantially U-shaped, and bosses 25d, which are formed on both sides of the connector body 25a to protrude. The bosses 25d are coupled to the frame <NUM> so that the connector body 25a can be rotatably supported with respect to the frame <NUM>. Boss holes, into which the bosses 25d are inserted, may be provided at the frame <NUM>. As illustrated in <NUM>, a receiving hole 25b, which penetrates the connector body 25a, is formed at the center of the connector body 25a. The connector <NUM> further includes a latch 25c, which extends from the connector body 25a to protrude into the receiving hole 25b. European patent <CIT> provides a handle that is less likely to be damaged by external impact, a cartridge, and a razor including the handle and the cartridge.

The present invention provides a razor and an interconnect member thereof that are able to simplify the structure and mounting process and achieve single-point engagement to overcome the aforementioned deficiencies.

One objective of the present invention is to provide an interconnect member which simplifies the structure and the mounting process and enables single-point engagement.

Another objective of the present invention is to provide a razor which simplifies the structure and the mounting process and enables single-point engagement.

To achieve the mentioned above objective, an interconnect member for a razor includes a housing and support arms extending upwards from left and right sides of the housing respectively. The housing is provided with a receiving cavity therein, and the receiving cavity penetrates through an upper end surface to a lower end surface of the housing. The interconnect member further includes a resilient engaging arm extending upwards from a front side of the housing and a resilient biasing arm extending upwards from a rear side of the housing. A free end of the resilient engaging arm is bent towards the rear side of the housing and located in the receiving cavity, and a free end of the resilient biasing arm is bent towards the front side of the housing to form an abutment portion for a razor head and located above the free end of the resilient engaging arm.

Furthermore, by means of the resilient engaging arm, during insertion of the inserting portion of the handle into the receiving cavity, the free end of the resilient engaging arm is pushed by the inserting portion to resiliently deform in the direction far away from the resilient biasing arm, and the free end of the resilient engaging arm slides on the inserting portion until the free end of the resilient engaging arm is engaged with the engaging groove. Thus, the single-point engagement between the interconnect member and the handle can be realized by one resilient engaging arm, thereby simplifying the structure. Accordingly, the interconnect member can simplify the structure and mounting process. Thus, the single-point engagement between the handle and the interconnect member can be realized under the premise of ensuring the reliable engagement of the handle and the interconnect member. So, the razor can also simplify the structure and the mounting process, and the single-point engagement between the handle and the interconnect member can be realized under the premise of ensuring the reliable engagement of the handle and the interconnect member.

The accompanying drawings facilitate an understanding of the various embodiments of this invention. In such drawings:.

A distinct and full description of the technical solution of the present invention will follow by combining with the accompanying drawings.

Referring to <FIG>, a razor <NUM> includes a razor head <NUM>, a handle <NUM>, an interconnect member <NUM>, and an unlocking operating member <NUM> mounted on the handle <NUM>. Specifically, the interconnect member <NUM> includes a housing <NUM>, support arms <NUM>, a resilient engaging arm <NUM> and a resilient biasing arm <NUM>. The support arms <NUM> are extended upwards from left and right sides of the housing <NUM>, respectively, the resilient engaging arm <NUM> is extended upwards from a front side of the housing <NUM>, and the resilient biasing arm <NUM> are extended upwards from a rear side of the housing <NUM>. The housing <NUM> is provided with a receiving cavity <NUM> inside, and the receiving cavity <NUM> penetrates from an upper end surface <NUM> to a lower end surface <NUM> of the housing <NUM>, so that the handle <NUM> can be inserted into the receiving cavity <NUM> from the lower end surface <NUM>. A free end <NUM> of the resilient engaging arm <NUM> is bent toward the rear side of the housing <NUM> and located in the receiving cavity <NUM>. Preferably, the free end <NUM> of the resilient engaging arm <NUM> is an arc-shaped such that the free end <NUM> is smoothly engaged with an engaging groove 21a described below, but not limited to this. A free end <NUM> of the resilient biasing arm <NUM> is bent toward the front side of the housing <NUM> and protrudes to form an abutment portion <NUM>, and the abutment portion <NUM> is located above the free end <NUM> of the resilient engaging arm <NUM>. Preferably, the abutment portion <NUM> and the free end <NUM> are each in a straight bar shape, as shown in <FIG>, thereby effectively avoiding interference between the resilient biasing arm <NUM> and the resilient engaging arm <NUM> and ensuring the reliability of their respective operations. More specifically, as shown in <FIG>, the abutment portion <NUM> is a protruding portion which is extended from the free end <NUM> of the resilient engaging arm <NUM>, and the number of the abutment portion <NUM> is two. The handle <NUM> is provided with an inserting portion <NUM> that is capable of inserting in the receiving cavity <NUM>, and the inserting portion <NUM> is provided with the engaging groove 21a. When the inserting portion <NUM> is inserted into the receiving cavity <NUM>, the free end <NUM> of the resilient engaging arm <NUM> is engaged in the engaging groove 21a. Specifically, during insertion of the inserting portion <NUM> into the receiving cavity <NUM>, the inserting portion <NUM> pushes the free end <NUM> of the resilient engaging arm <NUM> toward a front side of the interconnect member <NUM> (i.e., in the direction indicated by the arrow D in <FIG> or <FIG>) to resiliently deform, which will cause the free end <NUM> of the resilient engaging arm <NUM> to slide on the inserting portion <NUM> of the handle <NUM>, so that the free end <NUM> of the resilient engaging arm <NUM> is engaged with the engaging groove 21a, as shown in <FIG>, <FIG>, <FIG> and <FIG>. Furthermore, the unlocking operating member <NUM> is capable of driving the free end <NUM> of the resilient engaging arm <NUM>, so that the unlocking operating member <NUM> drives the free end <NUM> of the resilient engaging arm <NUM> to resiliently deform. Specifically, when the unlocking operating member <NUM> is operated, the free end <NUM> of the resilient engaging arm <NUM> is resiliently deformed in the direction indicated by the arrow D in <FIG> or <FIG>. Accordingly, the free end <NUM> of the resilient engaging arm <NUM> is disengaged from the engaging groove 21a of the inserting portion <NUM> when the unlocking operating member <NUM> is operated, thereby disassembling the interconnect member <NUM> from the handle <NUM>. The razor head <NUM> is mounted on and supported by the support arms <NUM>, and the razor head <NUM> is pivoted back and forth around the support arms <NUM> to meet the requirements of shaving. The resilient biasing arm <NUM> is abutted against the razor head <NUM> to provide an elastic force to the razor head <NUM> while the razor head <NUM> pivots around the support arms <NUM>, so as to ensure the stability and reliability of the razor head <NUM> pivoting back and forth around the support arms <NUM>. It should be noted that the structures of the razor head <NUM> and the handle <NUM> are well-known structures in the art, which will not be repeated here.

More specifically, as shown in <FIG>, and <FIG>, the free end <NUM> of the resilient engaging arm <NUM> is provided with an upper surface <NUM>, a lower surface <NUM>, and an inclined surface <NUM> arranged to connect the upper surface <NUM> and the lower surface <NUM> and formed on a rear side of the free end <NUM>. Specifically, the inclined surface <NUM> is inclined forward from bottom to top of the free end <NUM>, so that during inserting into the receiving cavity <NUM>, the inserting portion <NUM> can smoothly pass through an intersection <NUM> of the inclined surface <NUM> and the lower surface <NUM> and then abut against the inclined surface <NUM>. On the other hand, the inclined surface <NUM> abuts against the inserting portion <NUM> (specifically against a rear groove wall <NUM> described below), so that the inclined surface <NUM> stops the inserting portion <NUM> from being pulling-out, thereby preventing accidentally disengage the inserting portion <NUM> from the free end <NUM> of the resilient engaging arm <NUM>. As shown in <FIG>, the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM> and an intersection <NUM> between the inclined surface <NUM> and the upper surface <NUM> are arc-shaped to realize a smooth transition. Thus, while the inserting portion <NUM> inserts into the receiving cavity <NUM>, the inserting portion <NUM> smoothly slides on the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM> and then abuts against the inclined surface <NUM>. By means of the intersection <NUM> between the inclined surface <NUM> and the upper surface <NUM>, the upper surface <NUM> does not obstruct the surface contact between the inclined surface <NUM> and the inserting portion <NUM>, which further ensures the reliability of the surface contact between the inclined surface <NUM> and the inserting portion <NUM>. More specifically, the upper surface <NUM> and the lower surface <NUM> are arcuate surfaces, the arc diameter of the upper surface <NUM> is greater than the arc diameter of the lower surface <NUM> so that the free end <NUM> forms the convex arc structure described above, but it is not limited thereto. Understandably, the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM> or the intersection <NUM> between the inclined surface <NUM> and the upper surface <NUM> is an arcuate transition as desired, and it is not limited thereto.

Referring to <FIG> and <FIG> again, the housing <NUM> is extended upward to from a left surrounding arm 41a and a right surrounding arm 41b, respectively. Specifically, the left surrounding arm 41a surrounds the receiving cavity <NUM> on the left side of the housing <NUM>, and the right surrounding arm 41b surrounds the receiving cavity <NUM> on the right side of the housing <NUM>. The resilient engaging arm <NUM> surrounds the receiving cavity <NUM> on the front side of the housing <NUM> and is spaced apart between the left surrounding arm 41a and the right surrounding arm 41b. A resilient biasing arm <NUM> surrounds the receiving cavity <NUM> on the rear side of the housing <NUM> and is spaced apart between the left surrounding arm 41a and the right surrounding arm 41b. Thus, the inserting portion <NUM> is surrounded by the left surrounding arm 41a, the resilient engaging arm <NUM>, the right surrounding arm 41b and the resilient biasing arm <NUM> from the circumferential direction. Thus, the free end <NUM> of the resilient engaging arm <NUM> can be firmly engaged with the engaging groove 21a by using one resilient engaging arm <NUM> when the inserting portion <NUM> is inserted into the receiving cavity <NUM>, thereby simplifying the structure of the interconnect member <NUM>. Specifically, the support arm <NUM> on the left side of the housing <NUM> is arranged on the left side of the left surrounding arm 41a at intervals, and the support arm <NUM> on the right side of the housing <NUM> is arranged on the right side of the right surrounding arm 41b at intervals. Therefore, the razor head <NUM> assembled on the support arms <NUM> will not interfere with the left surrounding arm 41a and the right surrounding arm 41b respectively during pivoting, thereby ensuring the reliability of the razor head <NUM> pivoting.

As shown in <FIG>, <FIG>, <FIG>, <FIG> and <FIG>, the unlocking operating member <NUM> includes a press part <NUM> slidably disposed on the handle <NUM> and a pushing rod <NUM> connected to the press part <NUM>. The pushing rod <NUM> is inserted into the inserting portion <NUM>, and the pushing rod <NUM> further extends into the engaging groove 21a and is located below the free end <NUM> of the resilient engaging arm <NUM>, so that when a user presses the press part <NUM>, the pushing rod <NUM> along with the press part <NUM> slides relative to the handle <NUM>. Further, the pushing rod <NUM> pushes the free end <NUM> of the resilient engaging arm <NUM> to generate resilient deformation, so as to disengage from the engaging groove 21a of the inserting portion <NUM>, thereby disengaging the free end <NUM> of the resilient engaging arm <NUM> from the engaging groove 21a of the inserting portion <NUM>. Preferably, the press part <NUM> and the pushing rod <NUM> are slidably arranged along a vertical direction of the handle <NUM>. Thus, when the press part <NUM> is slid in the direction indicated by the arrow next to the press part <NUM> in <FIG>, the pushing rod <NUM> slides along with the press part <NUM>, so the free end <NUM> of the resilient engaging arm <NUM> is pushed by the pushing rod <NUM> to resilientally deform in the direction indicated by the arrow D in <FIG> or <FIG>, thereby disengaging the free end <NUM> from the engaging groove 21a of the inserting portion <NUM> so as to remove the interconnect member <NUM> from the handle <NUM>.

As shown in <FIG>, a notch <NUM> of the engaging groove 21a is formed in a front surface 21b and an upper surface 21c of the inserting portion <NUM>, and a rear groove wall <NUM> of the engaging groove 21a is inclined from bottom to top of the handle <NUM> toward a front side of the handle <NUM>, such that the rear groove wall <NUM> matches the inclination of the inclined surface <NUM> and abuts against the inclined surface <NUM>. When the rear groove wall <NUM> of the engaging groove 21a abuts against the inclined surface <NUM>, the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM> is located in a space <NUM> between the rear groove wall <NUM> and a lower groove wall <NUM> of the engaging groove 21a, as shown in <FIG>. Specifically, the rear groove wall <NUM> and the lower groove wall <NUM> of the engaging groove 21a are both planes and the angle between the two is an acute angle. A left groove wall <NUM> and a right groove wall <NUM> of the engaging groove 21a are arranged obliquely from bottom to top of the handle <NUM> and approach each other, so that the free end <NUM> of the resilient engaging arm <NUM> is smoothly inserted into the engaging groove 21a during the insertion of the inserting portion <NUM> into the receiving cavity <NUM>. Besides, the left groove wall <NUM> and the right groove wall <NUM> are combined to effectively prevent the free end <NUM> of the resilient engaging arm <NUM> from swinging left and right. In order that the inserting portion <NUM> can easily and smoothly pass over the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM>, the rear groove wall <NUM> of the engaging groove 21a obliquely extends forward and upward to form a protruding pushing portion 21d having the same thickness, and the protruding pushing portion 21d is clamped between the free ends <NUM> and <NUM> of the resilient engaging arm <NUM> and the resilient biasing arm <NUM>, as shown in <FIG>. Of course, according to actual needs, the thickness of the protruding pushing portion 21d may be incrementally or decrementally arranged.

With reference to <FIG>, the engagement process of the handle <NUM> with the interconnect member <NUM> is illustrated. As shown in <FIG>, the handle <NUM> is inserted into the receiving cavity <NUM> of the interconnect member <NUM> in a direction indicated by the arrow beside the inserting portion <NUM> until an end of the protruding pushing portion 21d of the inserting portion <NUM> abuts against the intersection <NUM> between the inclined surface <NUM> and the lower surface <NUM>. When the end of the protruding pushing portion 21d abuts against the intersection <NUM>, the inserting portion <NUM> continues to be inserted into the receiving cavity <NUM> along its original direction, so that the free end <NUM> of the resilient engaging arm <NUM> is resilientally deformed in the direction indicated by the arrow D in <FIG> by the end of the protruding pushing portion 21d, as shown in <FIG>. As a result, the intersection <NUM> avoids being blocked by the end of the protruding pushing portion 21d of the inserting portion <NUM>, so as to allow the end of the protruding pushing portion 21d to pass over the intersection <NUM>. Accordingly, the intersection <NUM> enters the engaging groove 21a from the notch <NUM> of the engaging groove 21a. Further, under the action of the elastic force of the resilient engaging arm <NUM>, the intersection <NUM> slides along the rear groove wall <NUM> of the engaging groove 21a during the insertion of the inserting portion <NUM> into the receiving cavity <NUM> until the inclined surface <NUM> abuts against the rear groove wall <NUM>, as shown in <FIG>.

In comparison with the prior art, since the interconnect member <NUM> in the present application also includes a resilient engaging arm <NUM> extending upwards from the front side of the housing <NUM> and a resilient biasing arm <NUM> extending upwards from the rear side of the housing <NUM>. The free end <NUM> of the resilient engaging arm <NUM> is bent toward the rear side of the housing <NUM> and located in the receiving cavity <NUM>. The free end <NUM> of the resilient biasing arm <NUM> is bent toward the front side of the housing <NUM> to form an abutment portion <NUM> located above the free end <NUM> of the resilient engaging arm <NUM> correspondingly, so that the interconnect member <NUM> uses the resilient biasing arm <NUM> to replace the conventional combined structure formed by the pushing portion and the spring. Furthermore, by means of the resilient engaging arm <NUM>, during insertion of the inserting portion <NUM> of the handle <NUM> into the receiving cavity <NUM>, the free end <NUM> of the resilient engaging arm <NUM> is pushed by the inserting portion <NUM> to resiliently deform in the direction far away from the resilient biasing arm <NUM>, and the free end <NUM> of the resilient engaging arm <NUM> slides on the inserting portion <NUM> until the free end <NUM> of the resilient engaging arm <NUM> is buckled with the engaging groove 21a. Thus, the single-point engagement between the interconnect member <NUM> and the handle <NUM> can be realized by one resilient engaging arm <NUM>, thereby simplifying the structure. Accordingly, the interconnect member <NUM> can simplify the structure and mounting process. Thus, the handle <NUM> and the interconnect member <NUM> is ensured, and the single-point engagement between the handle <NUM> and the interconnect member <NUM> can be realized. So, the razor <NUM> can also simplify the structure and the mounting process, and the single-point engagement between the handle <NUM> and the interconnect member <NUM> can be realized under the premise of ensuring the reliable engagement of the handle <NUM> and the interconnect member <NUM>.

Notably, when the razor <NUM> shaves beard downward, the side of the interconnect member <NUM> facing the skin is referred to as the front side, and the side of the interconnect member <NUM> away from the skin is referred to as the rear side, the side of the interconnect member <NUM> on the left side is referred to as the left side of the interconnect member <NUM>, and the side of the interconnect member <NUM> on the right side is referred to as the right side of the interconnect member <NUM>. And, the side of the interconnect member <NUM> on the upper side is referred to as the upper end of the interconnect member <NUM>, and the side of the interconnect member <NUM> on the lower side is referred to as the lower end of the interconnect member <NUM>.
