Description

[Technical Field]

[0001] The present invention relates to a vacuum suction device, and more particularly to a vacuum suction device that is formed with a specific structure to enable easy attachment and detachment, while at the same time providing a firm and strong suction force. [Background technology]

[0002] Generally, vacuum suction devices are used to attach and fix various items to smooth walls, glass, tiles, and other structures using the vacuum suction force of a suction plate, and are widely used for various purposes in homes and offices.

[0003] The vacuum suction device has a structure in which the suction plate is vacuum-sucked to the attachment surface, so that anyone can easily attach and detach the vacuum suction device to the attachment surface without using any additional tools, and at the same time, damage or breakage to the attachment surface to which the vacuum suction device is attached is prevented, thereby providing the advantage of being very convenient.

[0004] The vacuum suction device can be classified into a simple suction type that is composed of only a suction plate made of a flexible material, and a composite suction type that combines a suction plate made of a predetermined material with a hard cover plate to provide a stronger suction force.

[0005] Meanwhile, the present applicant has disclosed in Korean Patent Registration No. 10-1156552, as an example of a vacuum suction device having a composite suction method, that "a vacuum suction device attached to a surface such as glass or tile by vacuum suction, has an insertion hole formed at the top of the vacuum suction device into which one side of a locking member is inserted so as to be installed so as to be rotatable, a plurality of rotation protrusions having hooks bent toward the insertion hole protrude radially from the inner surface outside the insertion hole, a plurality of locking protrusions protrude from the inner peripheral surface, and a lid consisting of a plurality of fixing pieces formed on the upper surface inside; a bottom plate having a plurality of coupling holes formed at the bottom so as to be positioned inside the vacuum suction device, and a plurality of stoppers contacting the locking protrusions of the lid so as to be rotated only within a certain range on the outer upper surface of the bottom plate, and a plurality of stoppers formed between the stoppers." a height adjusting member comprising side plates with slopes inclined at a certain angle so that the bottom surfaces of the locking protrusions move while contacting and sliding against each other, and with fixing grooves formed at one end of each slope to fix each locking protrusion; a plurality of elastic locking pieces that are connected to the inside of the height adjusting member and have a certain elasticity so that the fixing pieces of the lid move while contacting and sliding against each other, and the moving fixing pieces hang on the end sides to fix the lid; a central shaft with a connecting groove on the top surface of the center part so that it can be connected to the bottom of the lid, and a suction plate consisting of a plurality of connecting protrusions that are inserted into each connecting hole of the height adjusting member and connected to the bottom of the lid, and a central shaft with a connecting groove on the outer periphery

[0006] However, in the conventional vacuum suction device as described above, since an external force is applied with the cover attached to the center of the suction plate, it is not possible to continuously provide sufficient suction force when used for a long period of time, resulting in problems such as random movement and detachment. In addition, there is also a problem that urethane gel or the like must be further applied to the suction surface in order to provide the suction plate with sufficient suction force.

[0007] Furthermore, when the vacuum suction device is repeatedly attached and detached, damage to parts may occur during the rotation process using the height adjusting member and the cover provided with the elastic locking piece, resulting in a shortened product lifespan. Summary of the Invention [Problem to be solved by the invention]

[0008] Therefore, the present invention has been devised to improve the above-mentioned conventional problems, and its object is to provide a vacuum suction device that is formed into a specific structure using a composite suction method, has a very strong structure, allows for easy attachment and detachment operations, and at the same time, exerts strong suction power when used. [Means for solving the problem]

[0009] To achieve the above object, the vacuum suction device according to the present invention comprises a suction plate having a disk-like shape of a certain thickness and incorporating a disk-shaped insert with a coupling protrusion protruding from its center, the suction plate selectively applying suction force through its underside; a rotor having a cylindrical shape with a coupling hole formed therethrough in the center and guide protrusions formed on both sides of the outer periphery, the rotor being attached to the center of the upper surface of the suction plate via the coupling hole and the coupling protrusions of the insert; a base member having a disk-shaped suction plate coupling part below which the suction plate is incorporated, and a rotor coupling part formed in a cylindrical shape and protruding from the center of the upper surface of the suction plate coupling part to allow the rotor to move up and down, the rotor coupling part having a pair of rotor guide grooves and a pair of cap coupling grooves formed therethrough at predetermined positions on the outer periphery; and a cap having a flat cylindrical shape with an open lower surface and a through-hole formed in its center, the cap being rotatably attached to the upper part of the base member via a pair of hooks fixed to the pair of cap coupling grooves with the rotor coupling part of the base member passing through the through-hole, and applying external force to the rotor.

[0010] Preferably, the insert body incorporated in the suction plate is provided with a plurality of injection grooves radially formed at regular intervals and a plurality of injection holes formed between the injection grooves.

[0012] More preferably, the adsorption plate is made of a soft synthetic resin material.

[0013] Preferably, a plurality of elastic cutouts are formed around the coupling hole of the rotor to facilitate smooth installation of the insert coupling protrusion, and a locking step is formed at a predetermined height on the inner surface of the coupling hole to secure the head of the insert coupling protrusion.

[0014] Preferably, the outer circumferential surface of the rotor is provided with a plurality of contact ribs at regular intervals to firmly contact the inner circumferential surface of the rotor coupling portion of the base member when the rotor is raised and to prevent friction with the base member.

[0016] Preferably, a pair of hooks are formed at a location adjacent to the through-hole on the ceiling surface of the cap, protruding at an interval of 180° from each other, and guide protrusion coupling portions are formed on the ceiling surface and inner peripheral surface of the cap, into which guide protrusions of the rotor are fitted and fixed in the gaps between the pair of hooks. [Effects of the Invention]

[0017] According to the present invention as described above, a suction device that is provided to be suction-fixed to glass, tile, smooth wall surfaces, etc. and used to hang or fix and support various items can be formed in a specific structure, thereby providing an effect of providing a high-quality suction device that has a more solid structure and excellent suction power.

[0018] In other words, due to the characteristics of the soft synthetic resin material that makes up the suction plate, sufficient suction power can be provided without the need for an additional coating process such as urethane gel, and at the same time, the insert with a specific structure built into the suction plate prevents any deformation even when the suction plate is repeatedly attached and detached.

[0021] The present invention configured as above will now be described in detail with reference to the accompanying drawings.

[0022] Figure 1 is a perspective view showing the configuration of a vacuum suction device according to the present invention, Figures 2a and 2b are separated perspective views showing the configuration of a vacuum suction device according to the present invention, Figure 3a is a perspective view showing the operating state of a vacuum suction device according to the present invention, and Figure 3b is a cross-sectional view taken along lines A-A, B-B, and C-C in Figure 3a.

[0023] First, the vacuum suction device according to the present invention is embodied as a suction device that is fixed by suction to glass, tile, smooth wall surfaces, etc., and is formed with a specific structure to enable easy attachment and detachment operations, while also exhibiting strong suction power when attached.

[0024] Therefore, the vacuum suction device according to the present invention comprises an suction plate 20 that is injection molded with an insert 10 of a specific structure included therein, a rotor 30 that is rotatably mounted on the top of the suction plate 20 and applies an external force to the suction plate 20, a base member 40 in which the suction plate 20 and rotor 30 are built, and a cap 60 that is rotatably mounted on the base member 40.

[0025] The insert 10 has a generally circular plate shape with a connecting protrusion 12 protruding from the center of its top surface, and is manufactured as an integrated structure with the suction plate 20 through double injection molding. The insert 10 forms the framework of the suction plate 20, which is made of a soft material, and is configured to provide a smooth restoring force to the suction plate 20.

[0026] The insert 10 has a generally circular disk-shaped body with a plurality of injection grooves 14 formed radially at regular intervals, and a plurality of injection holes 16 are drilled between the injection grooves 14 to form a solid, integrated structure with the suction plate 20 through a predetermined injection process.

[0027] The coupling protrusion 12 of the insert 10 has an expanded head at its upper end, and is configured to be inserted into a locking step 32a provided in the coupling hole 32 of the rotor 30 and then fixed.

[0028] The suction plate 20 is a disc-shaped plate with a certain thickness in which the insert 10 is embedded, and is configured to selectively provide suction force through its lower surface. The suction plate 20 is made of a synthetic resin material with a soft hardness value, and can provide excellent suction force while reflecting both the elasticity and characteristics of a rubber material. Reference numeral 24 denotes a plurality of injection pressure support grooves drilled to support the injection pressure during the double injection process including the insert 10.

[0029] In addition, a pair of anti-slip ribs 22 are formed in a circular shape at regular intervals along the edge of the upper surface of the suction plate 20 to prevent any deformation or slippage due to external force.

[0030] The rotor 30 has a substantially cylindrical shape and is formed with a coupling hole 32 at the center thereof, into which the coupling protrusion 12 of the insert 10 is inserted and coupled. Guide protrusions 36 are formed at predetermined points on the outer periphery of the rotor 30, spaced 180° apart from each other. The rotor 30 is configured to be rotatably installed on the upper surface of the suction plate 20 through the coupling between the coupling hole 32 and the coupling protrusions 12 of the insert 10.

[0031] A plurality of elastic cutouts 34 are formed around the coupling hole 32 of the rotor 30 so that the coupling protrusion 12 of the insert 10 can be smoothly fitted in the cutouts 34, and a locking step 32a is formed at a certain height on the inner surface of the coupling hole 32 so that the expanded head of the coupling protrusion 12 can be inserted and fixed.

[0032] In addition, a plurality of contact ribs 38 are formed at regular intervals on the outer circumferential surface of the rotor 30 in the vertical direction. When the rotor 30 is lifted by an external force, the contact ribs 38 are firmly and tightly fixed to the inner circumferential surface of the rotor coupling portion 46 of the base member 40, and the curved contact ribs 38 reduce friction with the base member 40.

[0033] The base member 40 has a generally disk-like or flat cylindrical shape with an open bottom, and includes an attraction plate coupling part 42 in which the attraction plate 20 is incorporated at its bottom, and a rotor coupling part 46 that is generally cylindrical and protrudes from the center of the top surface of the attraction plate coupling part 42, and is incorporated to allow the rotor 30 to move up and down.

[0034] The rotor coupling portion 46 of the base member 40 is formed with a pair of rotor guide grooves 49 along the outer circumferential surface to guide the rotor 30 to ascend and descend, and a pair of cap coupling grooves 48 in which the cap 60 is rotatably mounted.

[0035] The cap coupling grooves 48 are provided by being drilled horizontally so that a pair of hooks 66 of the caps 60 face each other and can move horizontally within a range of 50 to 70 degrees (most preferably about 60 degrees).

[0036] The rotor guide groove 49 is formed in the gap of the cap coupling groove 48 and is inclined at a certain gradient so that the guide protrusion 36 of the rotor 30 is guided to ascend and descend within the same angle range as the hook 66.

[0037] In addition, a fixing groove 49a is formed at the upper end of each rotor guide groove 49, extending downward, so that the guide protrusion 36 of the rotor 30 is guided toward the upper end and fixed in the fixing groove 49a, thereby firmly maintaining the rotor 30 in an elevated position.

[0038] A pair of triangular position indicators 52 for guiding the position of the cap 60 are formed on the upper surface of the rotor coupling portion 46 of the base member 40 at 180° intervals.

[0039] Meanwhile, in this embodiment of the present invention, a fixing groove 50 for fixing a predetermined shelf 100, etc., via the corresponding vacuum suction device is formed and fitted horizontally on the upper surface of the rotor coupling portion 46 of the base member 40. In addition, it goes without saying that structures such as hooks, fixing rings 200, and various accessories can be integrally formed and provided at predetermined points on the base member 40 depending on the use of the corresponding vacuum suction device (see Figures 5a and 5b).

[0040] A pair of rib seating grooves 44 are formed on the ceiling surface of the suction plate coupling portion 42 of the base member 40 at positions corresponding to a pair of anti-slip ribs 22 protruding from the upper surface of the suction plate 20.

[0041] The cap 60 has a generally flat cylindrical shape with an open bottom and a through-hole 64 formed in the center, and is configured to be rotatably mounted on the upper part of the base member 40 with the rotor coupling part 46 of the base member 40 passing through the through-hole 64.

[0042] A pair of hooks 66 are formed at predetermined points adjacent to the through-holes 64 of the cap 60, spaced 180 degrees apart, to be fixed to the pair of cap coupling grooves 48 of the base member 40, respectively. Thus, the cap 60 is mounted on the upper part of the base member 40 in a state in which the pair of hooks 66 are guided within the cap coupling grooves 48 of the base member 40 and can rotate by a certain angle.

[0043] In addition, guide protrusion coupling parts 68 are formed on the ceiling surface and inner peripheral surface of the gaps between the pair of hooks 66, and the guide protrusions 36 of the rotor 30 that pass through the rotor guide grooves 49 of the base member 40 are sandwiched and fixed therein. Therefore, when the cap 60 is rotated, an external force for linking the rotor 30 is transmitted through the guide protrusions 36 fixed to the guide protrusion coupling parts 68, and the rotor 30 can be raised and lowered along the rotor guide grooves 49.

[0044] Reference numeral 62 denotes a status indicator that guides the direction of suction or release of the corresponding vacuum suction plate based on the position indicator 52 of the base member 40 when rotating the cap, and reference numeral 69 denotes a plurality of suction support ribs that function to reinforce the strength of the cap 60 and press the base member more firmly. Next, the operation of the present invention as described above will be explained in detail as follows.

[0045] The vacuum suction device according to the present invention is provided by combining into an integrated structure a suction plate 20 incorporating the insert 10, a rotor 30 attached to the connecting protrusion 12 of the insert 10, a base member 40 attached to the upper part of the suction plate 20 and the rotor 30 with the guide protrusion 36 of the rotor 30 penetrating the rotor guide groove 49, and a cap 60 rotatably attached to the upper part of the base member 40.

[0046] When the vacuum suction tool is to be attached to glass, tile, or a smooth wall surface, the suction surface of the suction plate 20 is first tightly attached to the predetermined attachment surface to which the vacuum suction tool is to be attached.

[0047] At this time, the position indicator 52 displayed on the base member 40 is set to a state indicating the loosened position of the state indicator 62 provided on the cap 60 (FIGS. 3a and 3b (a)).

[0048] Thereafter, when an external force is applied to the cap 60 while holding it to rotate it clockwise by a certain angle for vacuum suction by the vacuum suction tool, the pair of hooks 66 on the cap 60 rotates horizontally within the cap coupling groove 48 of the base member 40, and at the same time, the pair of guide protrusions 36 on the rotor 30 rotates upward by a certain angle along the rotor guide groove 49 of the base member 40 while being interlocked with the guide protrusion coupling portion 68 of the cap 60 (FIGS. 3a and 3b (a)).

[0049] The cap 60 is rotated within a range of approximately 50 to 70 degrees when the hook 66 moves from one end of the cap coupling groove 48 to the other, and in this state, the position indicator 52 displayed on the base member 40 indicates the locked position of the status indicator 62 provided on the cap 60.

[0050] In addition, the guide protrusion 36 of the rotor 30, which has moved along the rotor guide groove 49 of the base member 40, is positioned in the fixing groove 49a provided at the upper end of the rotor guide groove 49. At this time, a plurality of contact ribs 38 formed along the outer circumferential surface of the rotor 30 abuts against the inner circumferential surface of the rotor coupling portion 46 of the base member 40, maintaining a firm fixing state without any shaking ((c) of Figures 3a and 3b).

[0051] That is, as shown in FIGS. 3a and 3b, when an external force for rotation is applied to the cap 60 around the base member 40 fixed at a predetermined point, the rotor 30, whose guide protrusion 36 is fixed to the cap 60, rotates together with the cap 60 and simultaneously rises by a certain height via the rotor guide groove 49 of the base member 40.

[0052] Meanwhile, as the guide protrusion 36 of the rotor 30 rises by a certain angle through the rotor guide groove 49 of the base member 40, the coupling protrusion 12 of the insert 10, which is inserted through the coupling hole 32 of the rotor 30, also rises in conjunction with the guide protrusion 36. As a result, the center of the suction plate 20, which forms an integrated body with the insert 10 built in, is lifted, and a certain distance is created between the center of the suction plate 20 and the corresponding attachment surface, creating a vacuum.

[0053] At this time, the anti-slip ribs 22 provided on the upper surface of the suction plate 20 prevent any deformation of the suction plate 20 when it moves, and also prevent the suction plate 20 from being crushed. The insert 10 built into the suction plate 20 also forms the framework of the suction plate 20, and acts to ensure that the central portion of the suction plate 20 rises and returns to its original position smoothly without twisting.

[0054] Therefore, a strong suction force is maintained between the attachment surface and the suction plate 20 due to vacuum suction, so various shelves 100 and various items can be attached using the fixing grooves 50 or hooks provided on the vacuum suction device (see Figure 4).

[0055] In order to separate the vacuum suction device from the corresponding attachment surface, the cap 60 is gripped and then an external force is applied to rotate the cap 60 counterclockwise, causing the rotor 30 and the insert 10 to descend by a certain height, thereby releasing the vacuum state formed between the center of the suction plate 20 and the attachment surface, and allowing the suction plate 20 to be converted into a state in which it can be easily separated from the attachment surface.

[0056] On the other hand, although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications and alterations may be made by a person having ordinary knowledge in the technical field to which the invention pertains within the scope of the claims, without departing from the gist of the present invention. Furthermore, such modifications and alterations should not be understood individually from the technical ideas and prospects of the present invention.
