Description

MANUAL CLIPPER ASSEMBLY

This invention relates to a manual clipper assembly, more particularly to a manual clipper assembly with a curved clipper blade for trimming hair growing from curved body surfaces.

Referring to Figure 1, a conventional shaving device 1 is used to brush and trim pet hair. The shaving device 1 includes a handle 11, a flat comb member 12 disposed at one end of the handle 11, a blade 13 mounted to the flat comb member 12, and a cover 14 for securing the blade 13 onto the flat comb member 12.

The flat comb member 12 includes two rows of teeth 121 formed respectively on opposite sides of the flat comb member 12. Each tooth 121 has a tip portion 122 and a base portion 123. Each row of the teeth 121 is arranged in a straight line.

The blade 13 includes opposite straight blade edges 131. Each straight blade edge 131 is disposed between the tip portions 122 and the base portions 123 of a corresponding row of the teeth 121.

Referring to Figure 2, while the two rows of teeth 121 and the blade edges 131 are respectively formed in a straight line as described above, the bodies of most pets are curved. Therefore, a disadvantage of the conventional shaving device 1 is that non-uniform trimming may occur, resulting in a coat for the pet that is unevenly cut. Another disadvantage is that only a small trim area is achieved for each stroke of the shaving devicel. Asaconsequence, the trimming operationmust be repeated multiple times in each area.

It is an object of the present invention to provide a manual clipper assembly that can overcome the above

drawbacks of the prior art.

According to the present invention, a manual clipper assembly includes a handle unit, and a clipper blade having a plate member, a comb portion, and a plurality ofblades. Thehandleunit includesanelongatedhandle, and a mounting seat disposed on one end of the handle.

The clipper blade is mounted on the mounting seat of the handle unit.

The plate member has a geometric center, and defines a first line and a second line passing through the geometriccenterandthatareperpendiculartoeachother.

The plate member has a pair of lateral edges spaced apart from each other along the direction of the first line, a rear edge interconnecting the lateral edges and disposed at one side of the first line, and a front edge interconnecting the lateral edges and disposed at the other side of the first line. The front edge is curved inwardly toward the first line such that a center portion of the front edge is closer to the first line than opposite ends of the front edge.

The comb portion is disposed on the front edge of the plate member, and includes a plurality of spaced-apart teeth of substantially equal length and extending from the front edge of the plate member away from the first line away from the first line. Adjacent pairs of the teeth respectively define grooves therebetween.

The blades extend from the front edge of the plate member away from the first line respectively in the grooves.

Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which: Figure 1 is an exploded perspective view of a conventional shaving device; Figure 2 shows the shaving device of Figure 1 in a state of use; Figure 3 is a perspective view of the preferred embodiment of a manual clipper blade according to the present invention; Figure 4 shows a front view of Figure 3; Figure 5 is a sectional view of the manual clipper blade taken along the line V-V of Figure 4; Figure 6 shows the manual clipper blade of the preferred embodiment in a state of use; Figure 7 is a perspective view of a modified example of the preferred embodiment of the manual clipper blade according to the present invention; Figure 8 is an exploded perspective of the preferred embodiment of a manual clipper assembly according to the present invention; and Figure 9 is a partly sectional side view of the manual clipper assembly shown in Figure 8.

Referring to Figures 3, 4, 8, and 9, the preferred embodiment of a manual clipper assembly according to this invention includes a handle unit 3, and a clipper blade 2 having a flat plate member 21, a comb portion 22, and a plurality of blades 23. The clipper blade 2 is small, lightweight, made of a metal material, and suitable for use on small animals, such as guinea pigs, small dogs and cats, etc. The handle unit 3 includes an elongated handle 31, and a mounting seat 32 disposed on one end of the handle 31. The clipper blade 2 is mounted on the mounting seat 32 of the handle unit 3.

The plate member 21 of the clipper blade 2 has a geometriccenter, anddefinesafirstlineLiandasecond line L2 (see Figure 3) passing through the geometric center and that are perpendicular to each other. The plate member 21 has a pair of lateral edges 211 spaced apart from each other along the direction of the first line Li, a rear edge 212 interconnecting the lateral edges 211 and disposed at one side of the first line Li, and a front edge 213 interconnecting the lateral edges 211 and disposed at the other side of the first line Li. The front edge 213 is curved inwardly toward the first line Li such that a center portion of the front edge 213 is closer to the first line Li than opposite ends of the frontedge2l3. Inthepreferredembodiment, the front edge 2i3 is symmetrical relative to the second line L2 and a center point thereof is closest to the first line Li while opposite ends of the front edge 213 are farthest from the first line Li. However, in some embodiments, the front edge 213 may be outwardly curved in such a manner that the ends of the front edge 213 are closest to the first line Li.

The comb portion 22 of the clipper blade 2 is disposed onthefrontedge2l3oftheplatemember2l, andincludes a plurality of spaced-apart teeth 221 of substantially equal length and that extend from the front edge 213 of the plate member 21 away from the first line Li. Each tooth 221 includes a base portion 223 and a tip portion 224. Adjacent pairs of the teeth 221 respectively define grooves 222 therebetween.

With further reference to Figure 5, the blades 23 of the clipper blade 2 extend from the front edge 213 of the plate member 21 away from the first line Li respectively in the grooves 224. In the preferred embodiment, a cross section of each of the blades 23 extends in a direction parallel to the second line L2 and is tapered. Such a configuration allows the blades 23 to cut hair in both directions. That is, regardless of which direction pet hair is passed through the grooves 224, the blades 23 are able to cut the hair.

Reference is now made to Figures 8 and 9. The manual clipper assembly further comprises a cover 4 detachably mounted to the mounting seat 32 of the handle unit 3.

The cover4andthemounting seat 32 interposethe clipper blade 2 therebetween. Themounting seat 32is formed with a pair of threaded apertures 321 in the preferred embodiment. However, in some embodiments, the mounting seat 32 may be formed with only one threaded aperture 321 or more than two threaded apertures 321. The cover 4 has two first through-holes 41 corresponding in locationtothe two threaded apertures 321. The clipper blade 2 has two second through-holes 214 corresponding in location to the pair of threaded apertures 321. The number of the first and second through-holes 41, 214 may be varied so as to correspond to the number of the threaded apertures 321.

To assemble the manual clipper assembly, the first through-holes 41 of the cover 4 and the second through-holes 214 of the clipper blade 2 are aligned with the threaded apertures 321 of the mounting seat 32, after which the cover 4 and the clipper blade 2 are secured to the mounting seat 32 via a pair of fasteners 45. In some embodiments, the threaded apertures 321 of the mounting seat 32 may be replaced by two protrusions (not shown) that are insertable respectively into the second through-holes 214 of the clipper blade 2.

As illustrated in Figures 3 and 5, the thickness of the base portions 223 of the teeth 221 in a direction perpendicular to the first and second lines Li, L2 is substantially equal to that at the front edge 213 of the plate member 21. The opposite lateral sides of the teeth 221 are formed with smooth surfaces and are tapered in a direction away from the front edge 213 of the plate member 21 (i.e., the tip portion 224 of each tooth 221 has a thickness less than that of the base portion 223 thereof) . Hence, pet hair may be easily combed, with the teeth 221 of the comb portion 22 effortlessly and deeply slipping into the coat of a pet.

Referring to Figure 9, the handle 31 defines a third line L3 that extends along a longitudinal axis of the handle 31. The third line L3 forms substantially an obtuse angle (9) with the second line L2 of the plate member 21, and a right angle with the first line Li of the plate member 21 of the clipper blade 2. Such an angular relationship between the handle 31 and the clipper blade2allows for optimal handlingof themanual clipper assembly.

Referring to Figure 7, in a modified example of the preferred embodiment, the clipper blade 2 may further comprise a grip portion 24 that is mounted on the rear edge2i2oftheplatemember2l, andthathasathickness greater than the thickness of the plate member 21. In this modified example of the preferred embodiment, the lateral edges 211 of the plate member 21 may be indented towards the second line L2.

The modified example of the preferred embodiment allows the clipper blade 2 to be more easily used as a stand-alone device without requiring the use of the handle unit 3. In the modified example of the preferred embodiment, the grip portion 24 and even the lateral edges 211 may be held by the user when trimming pet hair.

However, it is noted that the clipper blade 2 of Figure 3withoutthegripportion24and/ortheinwardlyindented lateral edges 211 may also be used as a stand-alone device without requiring the handle unit 3, as shown in Figure 6.

The manual clipper assembly of Figure 8, the clipper blade 2 of Figure 3, and the clipper blade 2 of Figure 7 of the present invention are advantageous in that the teeth 221 and the blades 23 are curvedly arranged with respecttothefirstlineLl. Duetosuchaconfiguration, the teeth 221 and the blades 23 can conform to the curved surfacesofapet'sbodyas shown, forexample, in Figure 6. Therefore, uniform trimming can be realized, and a wider cutting area may be achieved so that repetitive trimming of the same area is unnecessary.
