In addition, Figure 4 is a view for explaining the upper slider according to the present invention, Figure 4 (a) is a perspective view for explaining the configuration of the upper slider 30, Figure 4 (b) is an upper slider and the lower slider ( 20 is a cross-sectional view of the state in which it is bound. The first embodiment of the mobile phone slider according to the present invention shown in Figures 2 to 4 is an embodiment to which the first embodiment 40 of the elastic member is applied. A first embodiment of a mobile phone slider according to the present invention will be described with reference to FIGS. 2 to 4 as follows.

The mobile phone slider according to the present invention has a flat plate-shaped lower slider 20, an upper slider 30 mounted on the lower slider and sliding up and down along the lower slider, and both ends of the lower slider and the upper slider, respectively, the upper slider. It includes an elastic member 40 for supporting the vertical sliding of the. The lower slider 20 is fixedly installed on the receiver 1 of the sliding cellular phone on which the LCD screen and voice output unit are installed, and the upper slider 30 is fixed on the communication unit 5 of the sliding cellular phone on which the key button and voice input unit are installed. Is installed. Therefore, FIG. 2 (a) shows a state in which the receiver of the sliding cellular phone is lowered to close the call unit, and FIG. 2 (b) pushes the receiver to the state where the call unit is opened. On the other hand, the lower slider 20 may be fixedly installed in the communication unit 5 and the upper slider 30 may be fixedly installed in the receiver 1. Hereinafter, for convenience of description, the lower slider 20 will be fixed to the receiver 1 of the sliding cellular phone, and the upper slider 30 will be described with reference to an embodiment fixedly installed to the communication unit 5 of the sliding cellular phone. Do it.

The lower slider 20 according to the present invention has a flat plate shape and is a component for inducing vertical sliding of the upper slider 30, and a rail shaft 22 serving as a rail for sliding the upper slider is mounted. The rail shaft 22 is mounted in a form surrounding both side portions of the lower slider, and is preferably formed in a 'U' shape. On the contrary, it is of course possible to have a rail shaft separated into two so as to be respectively bound to the left and right sides of the lower slider. Meanwhile, as illustrated in FIGS. 3A and 3B, the rail shaft 22 may be mounted in the upper or lower direction of the lower slider 20, respectively.

Rail shaft 22 according to the present invention, as shown in Figure 3 (a) and Figure 3 (b), "U" shaped so as to be able to insert the work at once when assembling both rails in one operation productivity This is improved. That is, since the rail shaft 22 which acts as a rail is "U" shaped, a rail is provided in both inserts by one insertion.

In addition, the rail shaft 22 can serve as an antenna in the cellular phone. That is, it can be used as a substitute for the antenna.

The rail shaft 22 of the "U" shape has a structure in which both rails are connected to each other, and thus can withstand external forces and deformation well.

In the present invention, it may be provided with a cushioning member 23 that can act as a buffer when the upper slider hits the top and bottom of the lower slider due to the vertical sliding of the upper slider. The fixing groove 24 is formed to penetrate one end of the elastic member 40 in a predetermined distance from one side of the left and right side of the lower slider 20.

On the other hand, the lower slider 20 is preferably made of an engineering plastic material. Engineering plastics are high-strength plastics used as industrial and structural materials. They are high-performance resins with a polymer structure that is stronger than steel, more malleable than aluminum, and more resistant to chemicals than gold and silver. The performance and characteristics of engineering plastics vary depending on their chemical structure, and are mainly classified into five types: polyamide, polyacetyl, polycarbonate, PBT (polyester resin), and modified PPO (polyphenylene oxide). What they have in common is that they are polymer materials ranging in size from hundreds of thousands to millions, unlike conventional plastics, which have molecular weights of several tens to hundreds of low molecular weight materials. Therefore, engineering plastics are excellent not only in strength and elasticity but also in impact resistance, abrasion resistance, heat resistance, cold resistance, chemical resistance, and electrical insulation, and their uses are not only for household goods, general goods, but also for cameras, watch parts, aircraft structural materials, and electronics. Can be used across. On the other hand, the development of fiber reinforced plastics (FRP), which is a composite material exhibiting stronger properties by mixing engineering plastics with glass fiber or carbon fiber, has been made.

If the lower slider 20 or the upper slider 30 uses a material containing iron, there is a problem affecting radio wave reception and transmission of the cellular phone. However, the use of engineering plastics does not contain iron, so there is no obstacle in the reception and transmission of radio waves. In addition, mass production is possible because of the production by injection mold. For example, one mold can produce one million to two million or more. If aluminum is used as in the prior art, it is difficult to mass-produce due to the nature of the material because the work by extrusion or drawing, die casting mold. For example, only 100,000 to 200,000 pieces can be produced in one mold, which causes a lot of investment costs.

In the case of using aluminum in terms of characteristics of the product, there is no difference in the fixed state, but it is easy to bend or deform due to external impact, in particular, torsion and dropping impact. When impact, torsion or impact is applied, it has more elasticity than iron and has excellent resilience, which can reduce malfunctions caused by product deformation.

The upper slider 30 according to the present invention is a component that is mounted on the lower slider 20 and slides up and down along the lower slider. Specifically, both side ends surround both side portions of the lower slider and the rail shaft 22 together. Is mounted. The upper slider 30 includes a frame 32 forming an outer frame of the upper slider and an insert member 36 formed by an insert molding method inside the frame.

The frame 32 according to the present invention forms a shape in which both ends are bent in a 'c' shape, and penetrates so that the other end of the elastic member 40 can be inserted into a predetermined distance from one side of the left and right sides of the frame. The formed fixing groove 34 is formed. The frame 32 is preferably formed of stainless steel in order to insert molding of the insert member, to maintain strength, and to reduce warpage and thickness and to prevent deformation and corrosion. Meanwhile, the fixing grooves 24 and 34 of the lower slider 20 and the upper slider 30 are formed to be inward of opposite sides. That is, each of the fixing grooves 24 and 34 of the lower slider and the upper slider is provided to face each other. For example, when the fixing groove 24 of the lower slider is formed on the left side, the fixing groove 34 of the upper slider is on the right side. To form. The opposite is also true. In addition, the fixing grooves 24 and 34 are not formed on the same extension line in the horizontal direction. This is to allow the upper slider 30 to move up and down.

Insert member 36 according to the present invention is a component formed by the insert molding method in the inner side of the two side portions of the frame 32, specifically the inner end of the 'C' shape of the both sides of the frame, the mutually opposed One side is formed with a rail shaft insertion groove 37 recessed so that the rail shaft 22 can be fitted respectively. The insert member 36 is preferably formed of an engineering plastic material. On the other hand, the lower portion of the insert member 36 extends in the direction in which the lower regions of the frame 32 are opposed to each other to form a departure prevention jaw 38. The departure prevention jaw 38 covers both side portions of the lower slider when the upper slider and the lower slider are coupled to prevent the upper slider from escaping from the lower slider.

As described above, the upper slider 30 is formed into the insert member 36 by molding the engineering plastic into the insert molding method inside the both side portions of the frame 32 made of stainless material, thereby producing the upper slider It can increase the efficiency of the process and improve the completeness of the product. If the entire upper slider 30 is formed of a metal such as aluminum, precise components such as the rail shaft insertion groove 37 and the separation prevention jaw 38 need to be molded, thereby increasing the difficulty of the process and making mass production difficult. . In addition, the rail shaft insertion groove 37 should be shaped so as to be in close contact with the rail shaft 22. Due to the nature of the process, a gap is generated between the rail shaft insertion groove and the rail shaft, thereby reducing the completeness of the product and reducing the defective rate. Raised. In addition, since both the rail shaft insertion groove and the rail shaft are made of a metal material, noise occurs when the upper slider is slid due to friction between the metals, and wear is severe. On the other hand, when the insert member 36 is molded by the insert molding method as in the present invention, it is easy to manufacture, thereby greatly improving the productivity of the product, and molding the insert member by molding of the engineering plastic so that the rail shaft insertion groove 37 ) Can be manufactured precisely with the correct size and shape. Therefore, since the rail shaft 22 is in close contact with the rail shaft insertion groove 37, it is possible to increase the completeness of the product. In addition, since the rail shaft insertion groove made of metal and the rail shaft made of engineering plastics come into contact with each other, it is possible to significantly reduce noise or wear problems. In addition, since the insert member 36 is molded into both side end portions of the frame after the molding of the frame 32, the release preventing jaw 38 may be formed without a separate molding process.

The elastic member 40 according to the present invention is a component for supporting the vertical sliding of the upper slider 30, the respective ends are coupled to the respective fixing grooves 24, 34 of the lower slider and the upper slider, the lower slider and the upper You will connect the slider. The configuration and operation of the elastic member 40 and the operation of the mobile phone slider will be described in detail below with reference to FIG. 5.

5 is a view for explaining the first embodiment of the elastic member according to the present invention, Figure 5 (a) is a cross-sectional view of the first embodiment of the elastic member according to the present invention, Figure 5 (b) is the present invention Is a perspective view of a first embodiment of an elastic member according to the present invention. The configuration and operation of the first embodiment of the elastic member according to the present invention will be described with reference to FIGS. 5A and 5B as follows.

The elastic member 40 according to the present invention includes a first support tube 41 having a spring 43 mounted therein, a first insertion rod 42 having one end inserted into an open end of the first support tube, The second support tube 44 with the spring 46 mounted therein, the second insertion rod 45 and the first support tube 41 and the second support having one end inserted into the open end of the second support tube. It includes a cover 47 for wrapping and fixing the outer circumference of the tube (44).

The first support tube 41 and the second support tube 44 are tubular components formed through the inside thereof, and have a structure in which the first end is opened and the remaining second end is blocked. The first support tube 41 and the second support tube 44 have the same configuration and are arranged in opposite directions to each other. That is, the second end of the second support tube 44 is arranged in the direction in which the first end of the first support tube 41 is disposed. In addition, the first support tube 41 and the second support tube 44 are arranged to alternate with each other. Therefore, the support tubes disposed in opposite directions to each other have a structure alternately arranged adjacent to each other, it is possible to configure the elastic member 40 in a stable and balanced manner. In addition, springs 43 and 46 are respectively mounted in the first support tube 41 and the second support tube 44, and one end of the spring is supported by the blocked second end of the support tube.

The first insertion rods 42 and the second insertion rods 45 are components that are respectively inserted into the open first ends of the first support tube 41 and the second support tube 44, and the diameters of the insertion rods are respectively. Is formed to be equal to or less than the diameter of each support tube. End portions of the insertion rods 42 and 45 inserted into the open first ends of the respective support tubes 41 and 44 are respectively supported by the springs 43 and 46. Therefore, each insertion rod can be elastically moved in the transverse direction along the support tube, the overall length of the elastic member 40 is adjusted in the horizontal direction in accordance with the movement of each insertion rod. Meanwhile, in order to prevent the insertion rods 42 and 45 from being separated from each of the support tubes 41 and 44, a locking jaw (not shown) is formed at each coupling portion of each of the support tubes and the respective insertion rods.

The cover 47 is a component for stably supporting the first support tube 41 and the second support tube 44, and is provided in a form surrounding the outer circumference of each support tube. That is, by wrapping and fixing the outer periphery of the portion where the first support tube 41 and the second support tube 44, which are arranged in opposite directions, overlap each other, the respective support tubes 41, 44 are inserted into the rods 42, 45. ) To prevent shaking or falling off. Therefore, it is possible to stably maintain the elastic motion of the elastic member 40 as a whole.

At least one of the first support tube 41, the first insertion rod 42, the second support tube 44, and the second insertion rod 45 is provided. Each exposed end of each first insertion rod 42 is provided. The portions are interconnected and fixed by the first cap 48, and likewise the exposed one end of each second insertion rod 45 is also interconnected and fixed by the second cap 49. The first and second cap portions 48 and 49 are components to which external force is applied to the elastic member 40, and fix adjacent insertion rods to allow insertion rods in the same direction to move simultaneously. Specifically, the first cap 48 is to hold the ends of the first insertion rods 42 adjacent to each other together so that each first insertion rods can move equally when a force is applied from the outside. Similarly, the second cap portion 49 holds the ends of each second insertion rod 45 together so that each second insertion rod moves simultaneously and identically by an external force. In addition, the fixing protrusions are respectively attached to the fixing groove 24 of the lower slider 20 and the fixing groove 34 of the upper slider 30 on the bottom surface of the first cap portion 48 and the upper surface of the second cap portion 49. 48a and 49a are respectively provided. Preferably, the cross-sections of the binding portions of the fixing grooves 24 and 34 and the fixing protrusions 48a and 49a of the first and second cap portions are formed in a circular shape, and are fixed to each of the fixing grooves according to the movement of the upper slider. Allow each fixture to rotate separately.

FIG. 5 shows an embodiment in which the first support tube 41 and the first insertion rod 42, the second support tube 44, and the second insertion rod 45 are each provided with two, respectively. Of course, the number and configuration of the support tubes 41 and 44 and the insertion rods 42 and 45 can be variously modified. For example, two first support tubes 41 and two first insertion rods 42 may be provided, and three second support tubes 44 and three second insertion rods 45 may be provided. Through this, it is possible to freely adjust the size of the elastic force of the elastic member, it is possible to stably maintain the elastic motion of the elastic member even if it has a high elastic force.

On the other hand, the elastic member 40 is not affected by the elastic force in the state where the upper slider 30 is fully raised (sliding cell phone closed) or the upper slider is fully lowered (the sliding cell phone is open). To be in a state. That is, the position of the fixing groove of the upper slider and the lower slider is adjusted so that external force (pressure) is not applied to the spring of the elastic member while the upper slider is fully raised or lowered completely. Specifically, the distance between the fixing grooves of the upper slider and the lower slider in the state of raising or lowering the upper slider may be configured to be the same as the entire length of the elastic member 40 in the absence of pressure.

The operation of the mobile phone slider according to the present invention by opening and closing the sliding mobile phone, that is, the vertical sliding of the upper slider and the operation of the elastic member will be described below.

When the user raises the receiver while the receiver is lowered, that is, the sliding cellular phone is closed, the upper slider 30 is drawn along the rail shaft 22 by the receiver. At this time, the fixing protrusion 48a of the first cap portion 48 of the elastic member 40 bound to the fixing groove 24 of the lower slider 20 is rotated along the fixing groove, and the upper slider 30 is fixed. The fixing protrusion 49a of the second cap portion 49 bound to the groove 34 is also driven by the upper slider while rotating along the fixing groove. In the state in which the upper slider 30 is raised upward, the distance between the fixing grooves of the upper slider and the lower slider is the farthest state, that is, the distance equal to the length of the elastic member 40 when no pressure is applied. On the other hand, since the distance between the two fixing grooves is gradually reduced as the upper slider is lowered, an external force (pressure) that pushes both cap portions 48 and 49 of the elastic member 40 is generated, thereby causing the first and second insertion rods to be lowered. 42 and 45 are pushed into the first and second support tubes 41 and 44 to compress the springs 43 and 46. Accordingly, the user is resisted to raise the handset by the elastic force of the spring, so that the upper slider 30 can be prevented from suddenly descending.

The distance between the fixing grooves of the upper slider 30 and the lower slider 20 is the shortest when the intermediate point, that is, both fixing grooves 24 and 34 are located on the same horizontal line, wherein the springs 43 and 46 are the maximum. To be compressed.

However, when the upper slider 30 passes through the intermediate point, the distance between both fixing grooves gradually increases, so that the external force applied to both cap portions 48 and 49 of the elastic member 40 is also reduced. Therefore, since the first and second insertion rods 42 and 45 inserted into the first and second support pipes 41 and 44 are pushed out by the restoring force of the springs 43 and 46, the length of the elastic member is gradually longer. You lose. That is, when the upper slider 30 is pushed down to an intermediate point, the length of the elastic member is increased by the restoring force of the springs 43 and 46, and the upper slider 30 is automatically pushed down. Therefore, since the upper slider can be stably lowered by the spring, it is possible to prevent the shock from being applied to the receiver.

After lowering the upper slider 30 completely, the first and second insertion rods 42 and 45 are separated from the first and second support tubes 41 and 44 due to the locking jaw of the elastic member 40. As a result, the upper slider can no longer be lowered to prevent the upper slider from falling off. In addition, since the exposed state of the first and second insertion rods 42 and 45 is supported by each spring unless a separate external force is applied, the upper slider can be prevented from descending. Therefore, it is possible to stably maintain the open state of the hydration unit.

When the user lowers the receiver by closing the receiver, the fixing protrusion 49a of the second cap portion 49 moves up along the fixing groove 34 due to the upward movement of the upper slider 30. As the first and second insertion rods 42 and 45 are pushed into the first and second support tubes 41 and 44, the length of the elastic member 40 is gradually reduced. That is, the springs 43 and 46 are compressed. On the other hand, when the upper slider 30 passes through the intermediate point, the first and second insertion rods 42 and 45 are pushed out by the restoring force of the springs 43 and 46, and the elastic member 40 gradually lengthens to the upper portion. The slider will automatically move up. Therefore, it is possible to prevent the upper slider from suddenly moving and to prevent the upper slider from escaping above the lower slider.

Figure 6 is a perspective view for explaining the operation of the second embodiment of the mobile phone slider according to the present invention, Figure 6 (a) is a state in which the upper slider 30 according to the present invention is raised up along the lower slider 20 6 (b) is a view showing a state where the upper slider is lowered along the lower slider according to the present invention. The second embodiment of the mobile phone slider shown in FIG. 6 is an embodiment to which the second embodiment of the elastic member according to the present invention is applied, and the configuration and operation of other components are the same as described above. Therefore, the following description will focus on the second embodiment of the elastic member.

A second embodiment of the elastic member according to the invention is shown in FIG. 7 is a view for explaining a second embodiment of the elastic member according to the present invention, Figure 7 (a) is a perspective view of the second embodiment of the elastic member, Figure 7 (b) is a second of the elastic member An exploded perspective view of the embodiment. A second embodiment of the elastic member according to the present invention will be described with reference to FIGS. 7A and 7B as follows.

In the second embodiment 50 of the elastic member according to the present invention, two rods 51 having an elongated rod shape, and guide portions 56 for guiding the transverse movements of the rods on the upper surface thereof are recessed, respectively. It includes a body portion 55 and a cover portion 58 covering the upper surface of the body portion. That is, in the second embodiment 50 of the elastic member according to the present invention, the two rods 51 mounted on the body portion 55 may vary in overall length through an operation of entering or exiting the body portion, respectively. It will work. To this end, a spring 54 having a predetermined elastic force is mounted on one end portion 52 of each rod 51 mounted on the guide portion 56. Hereinafter, for convenience of description, the two rods 51 will be referred to as first rods and second rods, respectively. Each component is demonstrated as follows.

First, the first and second rods 51 form an elongated bar shape and are symmetrically arranged in the same shape, and the rods are arranged in a staggered state without being disposed on the same line as each other. In addition, the groove 52a is formed at one end 52 of each rod 51 on which the spring 54 is mounted so that the spring can be stably mounted. More specifically, the one end portion 52 is formed in the shape of a trident, so that the spring 54 is fitted into the groove portion 52a formed between the middle branch 52b and the branches on both sides, and the middle branch 52b is It is desirable to form somewhat longer than the branches on both sides. In addition, the remaining end of each rod 51 is provided with a fixed shaft 53 for binding to the fixing grooves 24 and 34 of the lower slider 20 and the upper slider 30. The fixed shaft 53 has a circular cross section, like the fixing protrusions 48a and 49a formed in the first and second cap portions 48 and 49 of the first embodiment 40 of the elastic member shown in FIG. In order to achieve the role of the rotating shaft in a state in which the fixing grooves (24, 34) respectively attached.

On the other hand, one end portion 52 of the first and second rods 51 may be modified in a form in which two branches are formed instead of a trident shape in which three branches are formed. In this case, one end of the first and second rods has a form without the middle branch 52b in the above embodiment. In addition, the spring 54 is mounted to each of the two branches. Therefore, since the first rod and the second rod are respectively supported by two springs, the elastic force can be increased more than the embodiment in which the spring is mounted only on the middle branch.

Next, the body part 55 is a component to which the first and second rods 51 are mounted, and has two guide parts 56 recessed on the upper surface thereof so that each rod can be seated thereon. Accordingly, each of the guide portions 56 is formed in an inverted shape of one end portion 52 of the first and second rods 51 to be seated, and is formed at the middle branch 52b of one end portion of the first and second rods 51. The springs 54 are respectively arranged in the regions 56a of the corresponding guide portions. As described above, the first rod and the second rod are alternately arranged rather than collinear. For this purpose, the respective guide parts 56 are alternately arranged without being collinear with each other. For example, when the guide portion on which the first rod is mounted is formed on the opposite side, the guide portion on which the second rod is mounted is formed on the right side. Therefore, compared to the form in which the two guide parts 56 are arranged on the same line, the overall length of the body part 55 can be reduced by about half, so that the overall length of the second embodiment 50 of the elastic member is a mobile phone slider. Will be the appropriate length applicable to.

In addition, the engaging portion (not shown) is provided at the coupling portion of the body portion 55 and each rod 51 to prevent each rod from being separated from the body portion by elasticity of the spring 54.

On the other hand, the upper surface of the body portion 55, in order to combine the body portion and the cover portion 58 is provided with a plurality of engaging projections 57 protruding to a predetermined size toward the top.

The cover 58 is a component that covers the upper surface of the body portion 55, and specifically covers the upper surface region opened by the guide portion 56. The cover 58 has a plurality of coupling grooves 59 formed therethrough or recessed so that each coupling protrusion can be fitted at a position corresponding to each coupling protrusion 57 of the body portion. In addition, the fixed shafts 53 of the first and second rods 51 compressed into the body part 55 through the guide part may be located at both ends of the cover part 58 corresponding to the guide part 56. It is to form a recessed groove (58a) formed in a semi-circular shape so that.

In the state where no external force is applied to the second embodiment 50 of the elastic member, that is, the pressure in the transverse direction to each rod 51 is applied, one end portion 52 of each rod inserted into the body portion 55 is a guide portion. Supported by a spring 54 in 56. Therefore, the area of each rod 51 except the one end 52 is exposed to the outside of the body portion. Specifically, since the spring 54 disposed in the region 56a corresponding to the middle branch 52b of the one end of each rod 51 of the guide portion 56 supports the recess 52a of the one end of each rod, A state in which a predetermined region of each rod is exposed to the outside of the body portion, that is, a state in which the second embodiment 50 of the elastic member is relaxed is maintained stably. The state of the second embodiment 50 of the elastic member, as described above, the upper slider 30 of the mobile phone slider fully raised or lowered down the lower slider 20, that is, the sliding mobile phone It will be in the fully open or closed state.

On the other hand, when the transverse pressure is applied to each rod 51 of the second embodiment 50 of the elastic member according to the present invention, each rod is inserted into the body portion 55 is contracted state do. More specifically, each rod 51 exposed to the outside of the body portion 55 compresses the spring 54 while entering the inside of the body portion along the guide portion 56 by the pressure in the lateral direction. Therefore, the overall length of the second embodiment 50 of the elastic member is gradually shortened. The state of the second embodiment 50 of the elastic member is a state in which the upper slider 30 of the mobile phone slider is moved up or down along the lower slider 20, that is, an intermediate state of opening or closing the sliding mobile phone. Corresponds to

The third embodiment of the mobile phone slider shown in FIG. 8 is an embodiment to which the third embodiment of the elastic member according to the present invention is applied, and the configuration and operation of other components are the same as described above. Therefore, the following description will focus on the third embodiment of the elastic member.

A third embodiment of the elastic member according to the invention is shown in FIG. 9 is a view for explaining a third embodiment of the elastic member according to the present invention, Figure 9 (a) is a view of the elastic member in a state in which the upper slider 30 is fully raised along the lower slider 20 Fig. 9 (b) shows a third embodiment of the elastic member with the upper slider located at an intermediate point of the lower slider, and Fig. 9 (c) shows the upper slider. 3 is a diagram showing a third embodiment of the elastic member in a state of completely lowering along the lower slider. The third embodiment of the elastic member according to the present invention will be described with reference to FIGS. 9 (a) to 9 (c) as follows.

The third embodiment 60 of the elastic member according to the present invention consists of at least one first elastic piece 62a and at least one second elastic piece 64a having a predetermined elastic force and forming an elongated rod shape. Both ends 62b and 64b of the elastic piece and the second elastic piece form a state where they are coupled to each other. The first elastic piece 62a and the second elastic piece 64a face each other and form a radial shape. Therefore, the first elastic piece 62a and the second elastic piece 64a each have a bow-like shape. In addition, both ends 62b and 64b of the first elastic piece and the second elastic piece are coupled to the fixing grooves 24 and 34 of the lower slider 20 and the upper slider 30, respectively.

The operation of the third embodiment 60 of the elastic member according to vertical sliding of the upper slider 30 according to the present invention will be described below.

First, when the upper slider 30 located above the lower slider 20 is lowered, a pressure is applied to compress the combined ends of the first elastic piece 62a and the second elastic piece 64a. As the left and right widths of the elastic piece and the second elastic piece become narrower, the entire length of the elastic member 60 is shortened. On the other hand, when the upper slider passes through the intermediate point of the lower slider, that is, the points where both fixing grooves 24 and 34 form the same extension line in the horizontal direction, the first elastic piece 62a and the second elastic piece 64a which have been contracted. As the original state is restored, the left and right widths are widened. Therefore, the entire length of the elastic member 60 is increased and the upper slider 30 is pushed downward so that the upper slider is automatically slid down.

Next, even when the upper slider 30 located below the lower slider 20 is pushed upward, pressure is applied to the elastic member 60 until the upper slider reaches an intermediate point, thereby providing the first elastic piece 62a. And the second elastic piece 64a are contracted. On the other hand, when the upper slider 30 passes through the intermediate point, the pressure applied to the elastic member 60 is released to restore the first elastic piece and the second elastic piece so that the upper slider is pushed up.

As described above, the slider for slidably connecting the communication unit and the receiver of the mobile phone according to the present invention stably supports the vertical sliding of the upper slider so that an impact is applied to the receiver of the mobile phone or the upper slider is separated from the lower slider. Not only can it be prevented, but there is a remarkable effect of increasing the efficiency of the upper slider manufacturing process and product completion.

In other words, the slider for slidingly connecting the communication unit and the receiver of the mobile phone according to the present invention,

First, since the elastic member for supporting the vertical sliding of the upper slider is provided to raise or lower the handset of the sliding mobile phone, the resistance is generated by the elastic force of the elastic member to prevent the sudden movement of the hydration, thereby impacting the handset. Can be prevented from being applied,

Secondly, when the handset is raised or lowered by a certain height, the handset is automatically moved by the restoring force of the elastic member, which is convenient to use.

Thirdly, since the lower slider is made of engineering plastic, it can not only achieve excellent effects in strength, flexibility, productivity and economy, but also further improve the transmission and reception sensitivity of the mobile phone.

Fourth, since the upper slider is molded into the stainless steel frame using engineering plastic, the insert member is molded by the insert molding method, thereby facilitating not only the manufacturing process of the upper slider but also the manufacturing of components requiring sophisticated molding such as rail shaft insertion grooves. Can greatly improve the production efficiency,

Fifth, because the insert molding method is molded, the rail shaft insertion groove of the upper slider can be manufactured precisely so as to be in close contact with the rail shaft, thereby improving the completeness of the product,

Sixth, because the metal rail shaft and the engineering plastic rail shaft insertion groove is in contact with each other, the occurrence of noise or wear of the product during the sliding of the upper slider can be significantly reduced.

Seventh, it is possible to prevent the upper slider from escaping from the lower slider by providing a release prevention jaw in the lower portion of the upper slider,

Eighth, since the insert member is molded after the molding of the frame, it is possible to form the release prevention jaw without a separate molding process

Finally, it is possible to apply various types of elastic members to a wide range of applications.

While the preferred embodiments of the present invention have been described using specific terms, such descriptions are for illustrative purposes only, and it is understood that various changes and modifications may be made without departing from the spirit and scope of the following claims.
