Description

Desk with sliding mount

[0001] The present invention relates to a desk, and more particularly, to a desk that can adjust the position of a computer monitor, a broadcasting device such as a microphone, a lighting device, etc. by sliding them on the desk.

[0002] When purchasing a computer, it is common to purchase a dedicated computer desk with the monitor placed on the desk, the keyboard placed on a drawer-type stand, and the main unit placed at one end of the dedicated desk or at the bottom of the desk.

[0003] However, computer desks are different from regular desks in that the space above the desk is narrow, making it difficult to move around and inconvenient when working or studying.

[0004] Therefore, in recent years, it has become common to place a monitor on a regular work desk or student desk and place the main unit at the bottom of the desk instead of purchasing a dedicated computer desk. However, this method has the problem that the monitor takes up a significant portion of the space on the desk, making it difficult to fully utilize the desk space, and this causes inconvenience in work or study.

[0005] So, as presented in the prior art (registered utility model 20-0208039), a method was proposed in which a monitor stand in the form of a bendable arm is fixed to the edge of a desk.

[0006] The conventional monitor stand described above is a type of stand that secures a 'ㄷ' shaped clamp provided at one end of the stand by inserting it laterally from the back of the desk, as shown in Fig. 1, and then tightening the bottom of the desk top strongly with a tightening member.

[0007] However, the conventional monitor stand described above has various problems, but in particular, when the refracting arm is rotated to position the monitor in an appropriate position, there is a high possibility that the refracting arm will move out of the desk and collide with the wall or partition, so the desk cannot be placed close to the wall or partition and must be used at a certain distance from the wall, which makes it difficult to use the interior space efficiently. Furthermore, the monitor's power cord and video signal cords have to be placed behind the desk, making it more difficult to place the desk close to the wall or partition and also having an unsightly appearance.

[0008] Also, simply by tightening the clamping force of the clamping member, the clamping member was fixed to the edge of the desk top, and the monitor was placed on the opposite end of the clamp. This caused the monitor to shake easily even if the desk shook slightly, which caused instability, and the clamping member was gradually loosened by the shaking, which weakened the clamping force.

[0009] Meanwhile, with the recent spread of internet broadcasting such as YouTube, one-person broadcasting has become popular, and not only monitors but also broadcasting equipment such as microphones and lighting equipment are being used on desks. However, as explained above, the stands for these devices are fixed to the back of the desk with a 'ㄷ' shaped clip lamp, and thus have the same problems as the monitor stands described above.

[0010] The present invention has been devised to solve the problems of the above-mentioned prior art, and aims to provide a desk that does not interfere with a wall or partition when mounting a computer monitor, broadcasting equipment such as a microphone, lighting equipment, etc.

[0011] In addition, the present invention aims to provide a desk that can adjust the position of the above-described devices by sliding them on the desk.

[0012] In addition, the present invention aims to provide a desk that can very stably fix the above-described devices without shaking when sliding and fixing them on the desk.

[0013] In addition, the present invention aims to provide a desk equipped with a multipurpose sliding mount that can be used in a compatible manner with the various devices described above.

[0014] A desk equipped with a sliding mount according to the present invention for solving the above-described problem comprises: a top plate divided into a first partition plate and a second partition plate spaced apart from each other to form a sliding slit; a mount on which a monitor arm on which a monitor is mounted is installed, moves along the sliding slit, and is fixed to or spaced apart from the upper and lower surfaces of the first partition plate and the second partition plate with the sliding slit interposed therebetween to fix or release the monitor arm from the top plate; and a support leg supporting the divided top plate.

[0015] Here, the mount comprises a lower pressure plate arranged across the lower surfaces of the first and second partition plates with the sliding slit therebetween; an upper pressure plate arranged across the upper surfaces of the first and second partition plates with the sliding slit therebetween, and having a fixing member on which the monitor arm is installed; and a fastener that brings the lower and upper pressure plates into contact with or separates the upper plate.

[0016] More specifically, the lower pressure plate is formed of a plate-shaped lower base disposed across the lower surfaces of the first and second split plates, and a lower pillar vertically protruding from the center of the lower base at a predetermined height and placed between the sliding slits, and the upper pressure plate is formed of a plate-shaped upper base disposed across the upper surfaces of the first and second split plates, and an upper sleeve vertically protruding from the center of the upper base in the shape of a hollow cylinder, the lower portion of which is connected to the lower pillar and the upper portion of which is screw-fastened to the conversion adapter.

[0017] And, the fastener is composed of a rotary shaft that is fitted horizontally through the entire upper sleeve and the lower column while the upper sleeve is placed on the outside of the lower column, and a lever that is connected to both ends of the rotary shaft and presses and seals the upper pressure plate and the lower pressure plate toward the upper plate when rotating downward around the rotary shaft, and releases the pressurized seal from the upper pressure plate and the lower pressure plate when rotating upward around the rotary shaft.

[0018] In addition, the fastener may be formed with a spiral portion that is formed on the outer surface of the lower column and the inner surface of the upper sleeve and is spirally connected. In this case, the lower column may be formed with a stepped structure in which the upper portion where the spiral portion is formed has a larger diameter than the other portion that is placed in the sliding slit.

[0019] In addition, the lower base is provided with a rotation prevention block that is placed in the sliding slit and prevents rotation of the lower pressure plate when the lower and upper pressure plates are spirally coupled.

[0020] Meanwhile, the present invention may further include a conversion adapter that enables the mount to be compatible with various devices, such as monitors or microphones. One end of the conversion mount is screwed to the mount, and the other end is fitted with the monitor arm.

[0021] A desk equipped with a sliding mount according to the present invention has the following advantages.

[0022] First, the monitor's position is stably set by moving the mount with the monitor along the sliding slit and then fixing it at an appropriate location, so not only is it easy to change the monitor's position, but the lower and upper pressure plates simultaneously hold the split top plate, so the monitor can be stably fixed without shaking, and there is an advantage in that the mount can be minimized from coming loose for a long time.

[0023] Second, the mount with the monitor moves inside the sliding slit formed between the tabletops, not along the edge of the tabletop. This allows the mount to be installed inside the tabletop, rather than along the edge, allowing the desk to be positioned close to the wall without interference with the wall or partition, resulting in greater space utilization. Furthermore, because the monitor can be positioned closer to the desk, it can be easily moved forward, backward, left, and right.

[0024] Third, there is the advantage of being able to use it in a compatible manner with not only computer monitors but also broadcasting equipment such as microphones and lighting equipment, or using them together.

[0025] Fourth, the convenience of use is greatly improved as the fixing and releasing of the mount can be done directly from the top of the desk to adjust the position of the various devices described above.

[0031] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention. In describing the present invention, detailed descriptions of related known technologies will be omitted if they are deemed to obscure the gist of the present invention.

[0032] Hereinafter, an embodiment of a desk equipped with a multipurpose sliding mount according to the present invention will be described in detail with reference to the attached drawings.

[0033] FIGS. 2 and 3 are perspective views illustrating a desk equipped with a sliding mount according to the present invention, FIGS. 4 to 6 illustrate a sliding mount according to a first embodiment of the present invention, and FIGS. 7 and 8 illustrate a sliding mount according to a second embodiment of the present invention.

[0034] A desk equipped with a sliding mount according to the present invention is configured to include a top plate (10), a mount (20) installed on the top plate (10), and a support leg (30) supporting the top plate (10).

[0035] The above-mentioned tabletop (10) provides a space (or area) for placing various items, such as books, various learning materials, computer monitors, broadcasting equipment such as microphones, and lighting equipment. The tabletop (10) is formed by combining multiple segments to form a single tabletop (10). For example, the tabletop (10) is divided into two segments, namely, a first segment (10b) and a second segment (10c), to form a single desk.

[0036] These divided upper plates (10) are arranged so that their edges do not touch each other and are spaced apart from each other, thereby forming a sliding slit (10a) between the divided upper plates (10). That is, a sliding slit (10a) is formed between the first divided plate (10b) and the second divided plate (10c) so that the mount (20) slides while being spaced apart from each other.

[0037] The above mount (20) moves along the sliding slit (10a) formed between the first and second dividing plates (10b) (10c), and a monitor arm (40) on which a monitor (M1) is mounted is installed. When the mount (20) on which the monitor (M1) is mounted is moved along the sliding slit (10a), and a suitable location for positioning the monitor (M1) is determined, the mount (20) is fixed at that location so that the monitor (M1) does not move.

[0038] The above mount (20) is configured to include a lower pressure plate (21) placed on the lower surface of the upper plate (10), an upper pressure plate (22) placed on the upper surface of the upper plate (10), and a fastener (Fastener, 23) that attaches or separates the lower pressure plate (21) and the upper pressure plate (22) to the upper plate (10).

[0039] The lower pressure plate (21) is arranged on the lower surface of the upper plate (10), and is arranged across a plurality of divided upper plates (10), so that the sliding slit (10a) is positioned directly above. More specifically, the lower pressure plate (21) is composed of a plate-shaped lower base (21a) arranged across the lower surfaces of the first and second divided plates (10b) (10c), and a lower pillar (21b) that vertically protrudes from the center of the lower base (21a) to a certain height and is placed between the sliding slits (10a).

[0040] The upper pressure plate (22) is arranged on the upper surface of the upper plate (10) and is arranged at a position facing the lower pressure plate (21). More specifically, the upper pressure plate (22) is composed of a plate-shaped upper base (22a) arranged across the upper surfaces of the first and second dividing plates (10b) (10c), and an upper sleeve (22b) that vertically protrudes in the shape of a hollow cylinder from the center of the upper base (22). A monitor arm (40) on which a monitor (M1) is mounted is coupled to the upper sleeve (22b) side of the upper pressure plate (22).

[0041] The lower pressure plate (21) and the upper pressure plate (22) are connected to each other through the lower pillar (21b) and the upper sleeve (22b). To elaborate further, the lower pillar (21b) and the upper sleeve (22b) are connected to each other through an axial connection or a spiral connection. As a result, even if the upper pressure plate (22) and the lower pressure plate (21) are released from the state of being tightly coupled to the desk for the sliding movement of the mount (20), they are not completely separated and can be slidably moved on the desk. In other words, the upper pressure plate (22) and the lower pressure plate (21) can be slidably moved on the desk while maintaining the connection and increasing the gap between them. This connection structure will be described later.

[0042] Here, a thin friction reducing sheet (21d) (22d) may be provided on the upper surface of the lower pressure plate (21) and the lower surface of the upper pressure plate (22), respectively. This friction reducing sheet (21d) (22d) has a smooth surface and a low coefficient of friction, thereby preventing damage to the upper and lower surfaces of the top plate (10) of the desk when the mount (20) slides along the top plate (10) of the desk, and allows the monitor (M1) to move easily while providing a feeling of a fixed rail while moving smoothly. It is preferable that the friction reducing sheet (21d) (22d) be made of Teflon (PTFE).

[0043] By the above-described configuration, the mount (20) can stably move along the sliding slit (10a) by coupling the upper pressure plate (22) to the lower pressure plate (21) while the lower pillar (21b) of the lower pressure plate (21) is placed between the sliding slits (10a). In addition, the mount (20) can be fixed in close contact with or spaced apart from the upper and lower surfaces of the first partition plate (10b) and the second partition plate (10c) with the sliding slit (10a) interposed therebetween, thereby fixing or releasing the monitor arm (40) to the upper plate (10).

[0044] The above fastener (23) narrows the gap between the lower pressure plate (21) and the upper pressure plate (22) so that the mount (20) is firmly fixed at a specific position, or widens the gap between the lower pressure plate (21) and the upper pressure plate (22) so that the mount (20), which was firmly fixed at a specific position, can move along the sliding slit (10a).

[0045] A fastener (23) according to one embodiment of the present invention is implemented in a quick release method and a one-touch tightening method.

[0046] First, referring to FIGS. 4 to 6, the quick release method can be described. The fastener (23) can be configured as a lever (23b) connected to the rotation axis (23a) of the upper pressure plate (22). At this time, when the lever (23b) is rotated downwards around the rotation axis (23a), the upper pressure plate (22) and the lower pressure plate (21) are pressed and pressed against the upper plate (10). That is, the mount (20) is fixed to the upper plate (10) of the desk. Conversely, when the lever (23b) is rotated upwards around the rotation axis (23a), the upper pressure plate (22) and the lower pressure plate (21) are released from the press and press against the upper plate (10). That is, the mount (20) is released from the fixation to the upper plate (10) of the desk and can move along the sliding slit (10a).

[0047] For this, a quick release type fastener (23) is rotatably fitted so that the upper sleeve (22b) of the upper pressure plate (22) is positioned on the outside of the lower column (21b) of the lower pressure plate (21) while the rotation shaft (23a) horizontally penetrates the entire upper sleeve (22b) and the lower column (21b).

[0048] And, the lever (23b) is connected to both ends of the rotation shaft (23a) while forming an overall 'U' shape. The portion of the lever (23b) that is connected to the rotation shaft (23a) is formed in an overall circular shape and has an asymmetrical shape centered on the rotation shaft (23d). More specifically, when the lever (23b) is in a horizontal state, the portion of the lever (23b) that is connected to the rotation shaft (23a) has a structure in which the lower portion is thicker than the upper portion centered on the rotation shaft (23a).

[0049] The quick release type mount (20) according to the above-described configuration rotates the horizontal lever (23b) downwards so that the thick part of the lever (23b) presses the upper pressure plate (22) downwards to press the upper pressure plate (22) against the upper surface of the upper plate (10), and at the same time, pulls the lower pressure plate (21) upward to press it against the lower surface of the upper plate (10).

[0050] In this way, the quick release type mount (20) according to the present invention can be easily fixed and released by rotating a lever on the desk rather than having the user operate it while bending over under the desk, thereby greatly improving the convenience of use.

[0051] Next, referring to FIGS. 7 and 8, the one-touch tightening method will be described. The fastener (23) has a structure in which the upper pressure plate (22) and the lower pressure plate (21) are spirally connected. More specifically, the fastener (23) is composed of a spiral portion (23c) formed on the outer surface of the lower column (21b) of the lower pressure plate (21), and a spiral portion (23d) formed on the inner surface of the upper sleeve (22b) of the upper pressure plate (22).

[0052] Accordingly, when the upper pressure plate (22) is turned in one direction, the upper pressure plate (22) which is spirally connected to the lower pressure plate (21) is lowered toward the upper plate (10) to press the upper pressure plate (22) against the upper surface of the upper plate (10) and at the same time, the lower pressure plate (21) is pulled upward to press it against the lower surface of the upper plate (10). Conversely, when the upper pressure plate (22) is turned in the opposite direction, the upper pressure plate (22) is gradually separated from the upper plate (10) and the press is released from the upper plate (10).

[0053] At this time, the lower pillar (21b) of the lower pressure plate (21) has a stepped structure in the longitudinal direction. That is, the upper part of the lower pillar (21b) has a larger diameter than the lower part of the lower pillar (21b), and a spiral part (23c) is formed on the outer circumference. More specifically, the upper part of the lower pillar (21) has a diameter that fits tightly into the upper sleeve (22b), and a spiral part (23c) is formed on the outer circumference. The lower part of the lower pillar (21) has a smaller diameter than the upper part, and a diameter that can be placed in the sliding slit (10a) space, and no spiral part (23c) is formed on the outer circumference.

[0054] In addition, the lower base (21a) constituting the lower pressure plate (21) is provided with an anti-rotation block (21c). More specifically, on the left and right sides of the lower column (21b) in the lower base (21a), anti-rotation blocks (21c) in the shape of square blocks are arranged in a straight line. At this time, the anti-rotation blocks (21c) are placed in the space of the sliding slit (10a). As a result, even if the upper pressure plate (22) is rotated, the anti-rotation blocks (21c) are blocked by the wall surface forming the sliding slit (10a), thereby preventing the rotation of the lower pressure plate (21), thereby enabling stable spiral engagement or spiral disengagement.

[0055] In addition, the upper base (22a) constituting the upper pressure plate (22) is provided with a rotation handle (22c). More specifically, square plate-shaped handles (22c) are arranged in a straight line on both the left and right sides of the upper sleeve (22b) of the upper base (22a). This allows the user to easily rotate the upper pressure plate (22) by holding the protruding plate-shaped handles (22c).

[0056] Meanwhile, as mentioned in the background technology of the present invention, with the recent widespread use of Internet broadcasting such as YouTube, one-person broadcasting has become popular, and not only monitors but also broadcasting equipment such as microphones and lighting equipment such as lights are being used on desks.

[0057] The present invention provides a multi-purpose sliding mount that can be used interchangeably with the various devices described above. In other words, the present invention provides a sliding mount that can be used with various device mounts, such as a monitor (M1) mount, a microphone (M2) mount, and a light mount (not shown), all having the same structure. Here, the monitor mount or microphone mount has the same configuration as the monitor arm or microphone arm.

[0058] For this purpose, the present invention further includes a conversion adapter (50) connected in the middle between the mount (20) and the device stand.

[0059] As illustrated in FIGS. 9 and 10, the conversion adapter (50) has a hollow cylindrical shape with one end screwed to a mount (20) and the other end coupled to a device stand. To elaborate further, the upper portion of the conversion adapter (50) is coupled to the end of the device stand, and the lower portion of the conversion adapter (50) is spirally coupled to the upper sleeve (22b) of the upper pressure plate (22).

[0060] For this purpose, a spiral portion (53) is formed on the outer surface of the lower portion of the conversion adapter (50). Then, the end of the monitor arm (40a) is forcibly fitted into the upper portion of the conversion adapter (50). At this time, a through hole (51) through which a pressure bolt (52) passes is formed on the upper side of the conversion adapter (50) at the portion where the monitor arm (40a) is fitted, and a spiral portion (53) is formed on the inner surface of the through hole (51). As a result, as the pressure bolt (52) rotates in a spiral manner through the through hole (51) from the outside of the conversion adapter (50), it enters the inside of the conversion adapter (50) and presses the monitor arm (40a) tightly, thereby fixing it more firmly. An intermediate partition (54) is formed in the middle of the inside of the conversion adapter (50) to prevent the monitor arm (40a) from being excessively inserted.

[0061] In the above-described conversion adapter (50), a microphone arm (40b) on which a microphone (M2) is mounted can also be connected in the same manner instead of the monitor arm (40a).

[0062] Meanwhile, in the present invention, it was explained that the upper plate (10) is not composed of a single plate, but is composed in a form in which a plurality of upper plates (10) are combined while forming a sliding slit (10a) through which the clamp (20) can move. However, the division form of the upper plate (10) can be composed in various ways.

[0063] As illustrated in Fig. 11, two or more upper plates may take the form of being divided left and right, or may take the form of being divided front and back, or may take the form of being divided left and right and front and back.

[0064] In addition, the sliding slit (10a) can be configured in various shapes such as a straight shape, a curved shape, a folded shape, and a crossing shape depending on the shape and arrangement of the plurality of upper plates (10).

[0065] Although each embodiment of the present invention has been described above with reference to the drawings, it will be understood by those skilled in the art that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
