Description

[DESCRIPTION]
[invention Title]
SLIDING ASSEMBLY FOR SLIDING-TYPE MOBILE PHONES
[Technical Field]
The present invention relates, in general , to a sliding assembly for sliding-type mobile phones and, more particularly, to a sliding assembly for sliding-type mobile phones, which is coupled to a sliding-type mobile phone in such a way as to slide longitudinally, and is secured to each of a transmitter housing and a receiver housing of the mobile phone, thus allowing the receiver housing to slide longitudinally.
[Background Art] Generally, a mobile communication terminal called a mobile phone has developed as follows . The initial mobile phone had a weight of about 4kg and was carried on a user' s shoulder. As technology was gradually developed, the size and weight of the mobile phone were reduced. A mobile phone that weighs 8Og and can be completely accommodated in the user' s hand has appeared. Further, such a mobile phone had the shape of a military, walkie-talkie in the first stage . Thereafter, the mobile phone was developed into a bar-type mobile phone, a flip-type mobile phone, and a folding-type mobile phone . Recently, as the development of the mobile phone has continued, a sliding-type mobile phone has appeared.
As described above, the mobile phone has been developed according to the motto "smaller and lighter" , thus resulting in the miniaturization and lightness of several components . As such, the mobile phone which has been continuously developed according to the motto "smaller and lighter" was mainly used for voice calls in the first stage . The mobile phone has evolved to have the functions of a digital camera and a digital camcorder, in addition to having the voice call function which is the basic function.
As well known to people, the above-mentioned simple mobile phone having the function of a phone call has been rapidly developed. Thereby, new products having various functions, including a camcorder function, a mobile banking function, a gaming function, an MP3 function, a TV function, an audio/video (AV) equipment function, a PDA function, and other functions, have successively appeared on the market . That is, the mobile phone has become the most popular digital multimedia device . Meanwhile, the mobile phone which is developed as described above ushers in an "All-in-One" age in which the mobile phone has all of the functions of a credit card, a camera, a TV, a camcorder, and an identification card. That is, the mobile phone is the center of a ubiquitous information and communication living environment that has no limits with respect to time or space, and is thus becoming the hub of the information and communication society. The construction of a sliding assembly for a general sliding-type mobile phone will be described below. FIG. 1 is a perspective view showing the state where a general sliding-type mobile phone is opened. FIG. 2 is an exploded perspective view showing a conventional sliding assembly for sliding-type mobile phones . FIG. 3 is a perspective view showing the original position of a movable plate in the conventional sliding assembly for sliding-type mobile phones . FIG. 4 is a perspective view showing the state where the movable plate of the conventional sliding assembly for sliding-type mobile phones slides . FIG. 5 is a lateral sectional view showing the conventional sliding assembly for sliding-type mobile phones .
As shown in FIGS . 1 to 5, a sliding assembly 20 for a sliding-type mobile phone 10, according to the prior art, includes a fixed plate 22 , guide members 24 , a movable plate 26, and elastic members 28. The fixed plate 22 having a predetermined length defines the lower portion of the sliding assembly 20. The rod-shaped guide members 24 are longitudinally provided on both sides of the upper surface of the fixed plate 22, thus longitudinally defining outwardly open guide grooves 22a between the guide members 24 and the fixed plate 22. The movable plate 26 has on opposite ends thereof guide rails 26a which are bent in a "U" shape . The guide rails 26a engage with the guide grooves 22a, so that the movable plate 26 longitudinally slides over the upper surface of the fixed plate 22. The elastic members 28 are installed between the fixed plate 22 and the movable plate 26 to elastically move the movable plate 26.
In the conventional sliding assembly 20 constructed as described above, the lower fixed plate 22 is secured to the upper surface of a transmitter housing 12 defining a lower transmitter of the sliding-type mobile phone 10. The movable plate 26, which is coupled to the upper portion of the lower fixed plate 22 in such a way as to slide in a lengthwise direction, is secured to the lower surface of a receiver housing 14 defining an upper receiver. Each of the elastic members 28 is provided between the fixed plate 22 and the movable plate 26 in such a way that opposite ends thereof are coupled to the fixed plate 22 and the movable plate 26. Thereby, after the movable plate 26 is moved a predetermined distance during the longitudinal movement of the movable plate 26, the movable plate 26 slides due to elastic force acting in the moving direction.
However, since the conventional sliding assembly is constructed so that the rod-shaped guide members are longitudinally installed on both sides of the fixed plate, it is difficult to assemble the sliding assembly. Further, in order to manufacture the guide members, wire cutting is implemented and thereafter manual processing is required, so that it is difficult to achieve mass production. Furthermore, it is difficult to expect a reduction in manufacturing cost . Further, since the conventional sliding assembly is constructed so that the rod-shaped guide members are longitudinally installed on both sides of the fixed plate, it is difficult to minimize the thickness and weight of the sliding assembly. As a result, it is difficult to minimize the total thickness and weight of the sliding-type mobile phone .
Moreover, since the conventional sliding assembly is constructed so that the rod-shaped guide members are longitudinally installed on both sides of the fixed plate and the guide grooves are formed between the guide members and the fixed plate, an undesirable clearance is formed between the fixed plate and the movable plate . Therefore, undesirable movement may occur between the lower transmitter housing and the receiver housing due to the clearance, and in addition may cause the mobile phone to malfunction. [Disclosure] [Technical Problem]
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a sliding assembly for sliding-type mobile phones, which is constructed so that opposite ends of a lower fixed plate are curled, and opposite ends of a movable plate slidably coupled to the fixed plate are bent to correspond to the opposite ends of the fixed plate, thus minimizing the thickness of the sliding assembly, therefore minimizing the total thickness of the sliding-type mobile phone .

Thereby, the cost of the mobile phone is reduced.
Moreover, according to the present invention, the outer circumferences of the opposite ends of the fixed plate and the whole movable plate, especially sliding portions provided on the inner circumferences of the opposite ends of the movable plate, are plated with chromium (hard chromium plating) , thus increasing hardness and abrasion resistance, therefore preventing fine iron from being generated when the movable plate moves longitudinally, therefore providing excellent sliding capability to the movable plate .

The sliding assembly for sliding-type mobile phones, according to the present invention, has the object of minimizing the thickness of the sliding assembly, as described above . The sliding assembly includes a fixed plate having a predetermined width, and a movable plate slidably mounted to the surface of the fixed plate in such a way as to face the fixed plate . The opposite ends of either the fixed plate or the movable plate are curled, thus providing a pair of guide rails . Bents parts are provided on the opposite ends of the remaining one of the fixed plate and the movable plate, and correspond to the shape of the guide rails such that the bent parts are in surface contact with the guide rails and slide in a lengthwise direction of the fixed plate . The sliding assembly according to each embodiment of the invention will be described below.
First , as shown in FIGS . 6 to 10 , a sliding assembly 100 of a sliding-type mobile phone 10 (see, FIG. 1) , according to the present invention, is constructed so that guide rails 112 are curled inwards . The construction of the sliding assembly 100 is as follows . That is, the opposite ends of a fixed plate 110 are curled inwards, thus providing the tubular guide rails 112 each having a space therein. Bent parts 122 , which are bent to correspond to the shape of the guide rails 112 provided on the opposite ends of the fixed plate 110 , are provided on the opposite ends of the movable plate 120. Thereby, the movable plate 120 slides within a predetermined range in a lengthwise direction of the fixed plate 110.
Further, guide steps 114 are provided between the fixed plate 110 and the guide rails 112 provided on the opposite ends of the fixed plate 110. Each guide step 114 is bent twice in a height direction corresponding to the thickness of the section of each of the bent parts 122 provided on the opposite ends of the movable plate 120, and in an outward direction perpendicular to the height direction. As shown in FIG. 9, the guide steps 114, provided on the opposite ends of the fixed plate 110, prevent ends of the bent parts 122 of the movable plate 120 from protruding under the fixed plate 110.
That is, when the fixed plate 110 is coupled to the movable plate 120, the ends of the bent parts 122 of the movable plate 120, surrounding the guide rails 112 of the fixed plate 110, correspond to the surfaces of the guide steps 114 , thus preventing the ends of the bent parts 122 from protruding to the lower surface of the fixed plate 110. As such, in order to prevent the ends of the bent parts 122 of the movable plate 120 from protruding to the lower surface of the fixed plate 110 , the height of the vertical surface of each guide step 114 , which is bent twice in the height direction and in the outward higher than the thickness of the section of each bent part 122. In the sliding assembly 100 according to the invention constructed as described above, the fixed plate 110 is secured to the upper surface of a transmitter housing 12 which defines a transmitter provided at a lower position of the sliding-type mobile phone 10. Further, the movable plate 120 , which is coupled to the upper portion of the fixed plate 110 in such a way as to slide in a lengthwise direction, is secured to the lower surface of a receiver housing 14 which defines a receiver provided at an upper position of the sliding-type mobile phone 10. The receiver housing 14 is semi- automatically moved up and down by elastic members 130 which are installed between the fixed plate 110 and the movable plate 120, thus being opened or closed.
The sliding assembly 100 of the sliding-type mobile phone 10, according to the invention, constructed as described above, does not use additional rod-shaped guide members, unlike the prior art . The sliding assembly 100 is constructed so that the opposite ends of the fixed plate 110 are curled in a circular, elliptical, or polygonal shape, and the opposite ends of the movable plate 120 , coupled to the fixed plate 110 in such a way as to slide in a lengthwise direction, are bent to correspond to the opposite ends of the fixed plate 110. Thus, the sliding assembly 100 of the invention is thinner than the conventional sliding assembly. As a result, the overall thickness of the sliding-type mobile phone 10 can be further reduced.
Meanwhile, in the sliding assembly 100 according to the invention constructed as described above, the bent parts 122. provided on the opposite ends of the movable plate 120 surround the outer circumferences of the guide rails 112 provided on the opposite ends of the fixed plate 110, as shown in FIG. 9. As such, the reason why the bent parts 122 provided on the opposite ends of the movable plate 120 are constructed to surround the outer circumferences of the guide rails 112 is because the movable plate 120 is not separated from the fixed plate 110 in a longitudinal direction. Thus, when the fixed plate 110 and the movable plate 120 constituting the sliding assembly 100 according to the present invention are assembled with each other, the movable plate 120 coupled to the fixed plate 110 in such a way as to slide in a lengthwise direction thereof cannot be coupled to the fixed plate 110 in the vertical direction. That is, after the lower or upper ends of the bent parts 122 of the movable plate 120 are aligned with the upper or lower ends of the guide rails 112 of the fixed plate 110, the movable plate 120 is slidably coupled to the fixed plate 110.
According to the present invention, the tubular guide rails 112, which are formed by curing the opposite ends of the fixed plate 110 and have space therein, may have the sectional shape of a circle or an ellipse. Further, the guide rails 112 provided on the opposite ends of the fixed plate 110 may have the shape of a polygon, such as a triangle, a rectangle, a pentagon, or a hexagon.
Thus, the bent parts 122 , which are in surface contact with the tubular guide rails 112 having internal space and are formed by curling the opposite ends of the fixed plate 110, are coupled to slide in the lengthwise direction of the fixed plate 110 , and are provided on opposite ends of the movable plate 120 , also have semicircular shapes corresponding to the circular or elliptical shape, or a shape corresponding to half the shape of a polygon, such as a triangle, a rectangle, a pentagon, or a hexagon.
Further, according to the present invention, the fixed plate 110 and the movable plate 120 comprise a thin stainless steel plate . Chromium-plating layers 116 and 124 are respectively provided on the entire fixed plate 110 and the entire movable plate 120 , which are made of stainless steel . Particularly, all of the stainless steel comprising each of the fixed plate 110 and the movable plate 120 is plated with hard chromium, thus increasing hardness . This enhances abrasion resistance of the bent parts 122 of the movable plate 120 , which are in surface contact with the guide rails 112 of the fixed plate 110 and are slidably coupled in the lengthwise direction of the fixed plate 110 , thus affording excellent sliding capacity of the movable plate 120. In a detailed description, the fixed plate 110 and the movable plate 120 constituting the sliding assembly 100 according to this invention are wholly plated with hard chromium, thus increasing the hardness of the fixed plate 110 and the movable plate 120 , and in addition, increasing the abrasion resistance of the guide rails 112 and the bent parts 122. Thereby, the sliding capacity of the movable plate 120 sliding in the lengthwise direction of the fixed plate 110 is improved.
The process of treating the surface of metal using chromium is typically classified into a method using plating or deposition and a method using coating or chromate conversion coating . The type of chromium used in the process is a hexavalent chromium compound, which is currently used.
The chromium-plated layer formed by the plating process in the metal surface treating process using chromium is hard and has high density, so that it has a lower frictional coefficient than other metals in. Further, it has excellent abrasion resistance and corrosion resistance, and in addition, it is not easily faded. Such chromium plating is divided into hard chromium plating having a thick film and thin decorative chromium plating, according to the thickness of the plating film.
The hard chromium plating process is used in surface plating for printing plates, tools, molds, various shafts, etc . Further, it may be used to plate a cylinder or piston pin of an airplane engine . Further, porous chromium plating is performed by eroding a surface plated with hard chromium in a chromic acid solution, and was used for piston rings and cylinder bores in the Second World War. Meanwhile, the elastic members 130 are provided between the fixed plate 110 and the movable plate 120, which are arranged to be spaced apart from each other by a predetermined interval . The elastic members are installed between the fixed plate and the movable plate and apply a force such that the movable plate 120 slides in one direction, that is, upwards or downwards relative to the middle position of the fixed plate 110. The first end of each elastic member 130 is secured to the fixed plate 110 , while the second end of the elastic member 130 is secured to the movable plate 120. Thus, when the first and second ends of each elastic member 130 move along a straight line in one sliding direction, that is, upwards or downwards, an elastic force acts in that direction. According to this invention, torsion springs are used as the elastic members 130. The construction of the sliding assembly 100 according to this invention will be described below in detail . That is, the fixed plate 110 functions to longitudinally guide the movable plate 120, slidably coupled to the upper portion of the fixed plate 110. The opposite ends of the fixed plate 110 are inwardly curled in opposite directions, thus providing the tubular guide rails 112 having space therein.
Each of the tubular guide rails 112 , longitudinally- provided on the opposite ends of the fixed plate 110 constructed as described above, may have the sectional shape of a circle or an ellipse . The guide rail may have the sectional shape of a polygon, such as a triangle, a rectangle, a pentagon, or a hexagon. Further, the guide steps 114 are provided between the fixed plate 110 and the guide rails 112 provided on the opposite ends of the fixed plate 110, and are bent twice in a height direction and an outward direction perpendicular to the height direction.
Meanwhile, the guide steps 114 are bent twice in a height direction and an outward direction perpendicular to the height direction. Thereby, each guide step 114 has a vertical surface having a height corresponding to the sectional thickness of each of the bent parts 122 provided on the opposite ends of the movable plate 120 so that the ends of the bent parts 122 of the movable plate 120 do not protrude under the fixed plate 110. As described above, the guide rails 112 are formed by curling the opposite ends of the fixed plate 110 in a circular or polygonal shape, and the guide steps 114 are bent twice to prevent the ends of the bents parts 122 of the movable plate 120 from protruding under the fixed plate 110. Thus, the strength of the fixed plate 110 is considerably increased by the guide rails 112 and the guide steps 114 provided on the opposite ends of the fixed plate 110.
The movable plate 120 is slidably coupled to the fixed plate 110 , and slides in the lengthwise direction of the fixed plate 110 , thus opening or closing the mobile phone. The bent parts 122 are provided on the opposite ends of the movable plate 120 to correspond to the guide rails 112 formed on the fixed plate 110. In this case, the bent parts 122 are shaped to surround the outer circumferences of the guide rails 112 provided on the opposite ends of the fixed plate 110.
As described above, the bent parts 122 are constructed to surround the outer circumference of the guide rails 112 formed on the opposite ends of the fixed plate 110 , thus preventing the movable plate 120 from being separated from the fixed plate 110 in a vertical direction.
Thus, if each of the guide rails 112 provided on the opposite ends of the fixed plate 110 has a circular or elliptical shape, each of the bent parts 122 provided on the opposite ends of the movable plate 120 has a semicircular shape corresponding to the circular or elliptical guide rail . Meanwhile, if each guide rail 112 has the shape of a polygon, such as a triangle, a rectangle, a pentagon, or a hexagon, each of the bent parts 122 provided on the opposite ends of the movable plate 120 has half the shape of the polygon corresponding to the polygonal shape of the guide rail .
The chromium-plated layers 116 and 124 improve the hardness and the abrasion resistance of the fixed plate 110 and the movable plate 120, thus enhancing the sliding capacity of the movable plate 120. The chromium-plated layers 116 and 124 are formed over the entire fixed plate 110 and the entire movable plate 120 , which are made of stainless steel . Particularly, the outer circumference of the guide rails 112 provided on the opposite ends of the fixed plate 110 and the inner circumferences of the bent parts 122 provided on the opposite ends of the movable plate 120 may be plated with hard chromium so as to increase hardness and abrasion resistance .
As described above, the chromium-plated layers 116 and 124 are formed over the entire fixed plate 110 and the entire movable plate 120, which are made of stainless steel, thus further increasing the hardness of the fixed plate 110 and the movable plate 120. Further, the chromium-plated layers 116 and 124 are formed on the outer circumferences of the guide rails 112 provided on opposite ends of the fixed plate 110 and the inner circumferences of the bent parts 122 provided on opposite ends of the movable plate 120 , which are in surface contact with each other, thus preventing fine iron particles from being generated when the movable plate 120 slides repeatedly.
The elastic members 130 function to automatically slide the movable plate 120 in one direction, that is, upwards or downwards, at the middle position of the fixed plate 110 , when the movable plate 110 is moved up and down relative to the fixed plate 110. The elastic members 130 are installed between the fixed plate 110 and the movable plate 120. In this case, the first end of each elastic member 130 is secured to the fixed plate 110 , while the second end of each elastic member 130 is secured to the movable plate 120.
Meanwhile, a torsion spring is used as each of the elastic members 130, which are installed between the fixed plate 110 and the movable plate 120 such that the first end of each elastic member 130 is secured to the fixed plate 110 and the second end of each elastic member 130 is secured to the movable plate 120. Thus, when the first and second ends of each elastic member 130 are moved along a straight line in one sliding direction, that is, upwards or downward, the torsion spring acts an elastic force in the moving direction of the elastic member.

The sliding assembly 100a according to the second embodiment will be described below in detail with reference to FIGS . 11 to 15. That is, the sliding assembly 100a according to the second embodiment is constructed so that the opposite ends of the fixed plate 110a are curled outwards, thus providing the tubular guide rails 112 having space therein. Further, bent parts 122a are formed on the opposite ends of a movable plate 120a to correspond to the guide rails 112a formed on the opposite ends of the fixed plate 110a. Thereby, the movable plate 120a slides within a predetermined range in the lengthwise direction of the fixed plate 110a.
The sliding assembly 100a constructed as described above, according to the second embodiment, includes elastic members 130a comprising a torsion spring. The elastic members are installed between the fixed plate 110a and the movable plate 120a such that one end of each elastic member is supported by the fixed plate 110a and the other end of each elastic member is supported by the movable plate 120a. Thus, when the movable plate 120a moves up and down relative to the fixed plate 110a, the elastic members function to automatically slide the movable plate 120 in one direction, that is, upwards or downwards, from the middle position of the fixed plate 110a.

Unlike the first and second embodiments, the sliding assembly 100b according to the third embodiment of this invention further includes auxiliary sliding pieces 126b. The auxiliary sliding pieces 126b are formed by cutting three sides of portions of the upper surface of the movable plate 120b located at upper and lower positions on both sides thereof . The cut parts are curled according to the shape of each guide rail 112b. After the three sides of each of the portions at upper and lower positions on both sides of the upper surface of the movable plate 120b have been cut to provide the sliding piece 126b, the sliding piece 126b is bent downwards to correspond to the inside surface of each guide rail 112b. When each sliding piece 126b surrounds both sides of each guide rail 112b together with each bent part 112b of the movable plate 120b, a hole 126b-l is defined in a portion where each sliding piece 126b is cut .
That is, the sliding assembly 100b according to the third embodiment of this invention further includes the auxiliary- sliding pieces 126b provided to surround the guide rails 112b in the direction opposite the bent parts 122b, which are formed on the opposite ends of the movable plate 120b to correspond to the shape of the guide rails 112b. The three sides of each of the upper and lower portions of both sides on the upper surface of the movable plate 120b are cut and curled according to the shape of each guide rail 112b, thus providing the auxiliary sliding piece 126b.
As such, the sliding assembly further includes the auxiliary sliding piece 126b formed by cutting the three sides of each of the upper and lower portions of both sides on the upper surface of the movable plate 120b and curling the cut part according to the shape of each guide rail 112b, thus more efficiently preventing undesirable movement of the movable plate 120b, when the movable plate 120b is slidably mounted to the fixed plate 110b. Meanwhile, the sliding assembly 100a constructed as described above, according to the third embodiment, includes elastic members (not shown) comprising a torsion spring.

Further, each of the guide rails 112b provided on opposite ends of the fixed plate 110b of the sliding assembly
15 100b according to the third embodiment has the sectional shape of a circle, an ellipse, or a polygon. The opposite ends of the movable plate 120b slidably mounted to the fixed plate 110b are shaped to correspond to the shape of the guide rails 112b. 0 FIG. 19 is a side view showing the original position of a movable plate in a sliding assembly for sliding-type mobile phones, according to the fourth embodiment of the present invention. FIG. 20 is a perspective view showing the state where the movable plate of the sliding assembly for sliding- 5 type mobile phones, according to the fourth embodiment of the present invention, slides .
FIGS . 19 and 20 show a sliding assembly 100c according to the fourth embodiment of the present invention. The general construction of the fourth embodiment remains the same as the 0 sliding assembly 100, 100a, 100b, according to the first, second, third embodiment . However, the sliding assembly 100c of FIGS . 19 and 20, according to the fourth embodiment is different from those of the first to third embodiments in that a fixed plate 110c and a movable plate 120c have an arc shape . Thus, when a receiver housing 14c moves upwards, it slides along the arc-shaped fixed plate 110c, and the transmitter housing 12c and the receiver housing 14c form an open angle of 120 to 150 degrees .
In the sliding assembly 100c according to the fourth embodiment of this invention, when the receiver housing 14c moves upwards, it slides along the arc-shaped fixed plate 110c, and the transmitter housing 12c and the receiver housing 14c form an open angle of 120 to 150 degrees . As such, the transmitter housing 12c and the receiver housing 14c form an ergonomic open angle, thus allowing the mobile phone to be in closer contact with a user' s face.

As described above, the sliding assembly 100 for the mobile phone 10 according to the present invention is constructed so that the opposite ends of the fixed plate 110 and the movable plate 120 are curled to correspond to each other. Thereby, through the surface contact of the fixed plate 110 with the movable plate 120 , the movable plate 120 slides . Thus, the overall thickness of the sliding assembly 100 can be reduced to about 1.5mm, so that the overall thickness of the sliding-type mobile phone 10 can also be reduced considerably.
Moreover, the sliding assembly 100 for the mobile phone 10 according to the present invention is constructed so that the opposite ends of the fixed plate 110 and the movable plate 120 are curled to correspond to each other. Thereby, through the surface contact of the fixed plate 110 with the movable plate 120 , the movable plate 120 slides . Thus, the working period required for the production and assembly of a product is reduced, so that workability is increased, in addition to reducing the cost of the product .
The present invention may be variously changed within the scope of this invention without being limited to the above- mentioned embodiments .
