Description

CEILING HANGER

Technical Field

[I] The present invention relates to a ceiling hanger which firmly supports and fixes a member suspended from the ceiling and, in particular, to a ceiling hanger, which is more easily and simply installed on an anchor bolt for firm fastening work. Background Art

[2] As many ceiling- suspended members are used for increasing space utilization efficiency in modern construction, there is a need for a ceiling hanger that allows such ceiling- suspended members to be efficiently suspended from the ceiling.

[3] Typically, ceiling hangers are used for supporting various things such as ceiling panels, lighting implements, ceiling air conditioners, and electrical and air ducts by means of anchor bolts.

[4] As shown in FIG. 1, a fixing support 1 is fastened to an anchor bolt 3 using a ceiling as follows.

[5] A nut 21 is screwed onto the anchor bolt 3. Then, the fixing support 1 is fitted around the anchor bolt 3 up to the nut 21 using a through-hole Ib of its upper support shoulder Ia. Next, another nut 22 is screwed onto the anchor bolt 3 up to the upper support shoulder Ia.

[6] This conventional ceiling hanger has the following problems.

[7] Such a ceiling hanger requires a relatively long time for installation and many processes and complicated adjustment for acquiring a balance between forces applied to the anchor bolt 3 and the fixing support 1.

[8] When a carrying channel 50 is installed to fix the ceiling panel as in FIG. 1, the force balance is often ignored due to reduction in working time and labor costs.

[9] The fixing support 1 is made by cutting, bending, and punching a steel plate having a thickness of 2mm or more. In order to prevent the carrying channel 50 from being separated from the fixing support 1, the fixing support 1 is provided with a plurality of holes Ic, Id, and Ie into which a fixing pin 101 is inserted, which incurs inconvenience.

[10] Further, the fixing support 1 is not firmly fixed, and is used as a supporting means with a great tolerance, thereby requiring much time for the adjustment.

[I I] Also, since the fixing support 1 is made of a steel plate, its edges are sharp. Thus, because these sharp edges make it possible to hurt any worker (user) due to incorrect treatment, the worker (user) must always pay attention. This leads to reducing working efficiency. The fixing support 1 is fixed to the anchor bolt 3 by screwing the nuts 21 and 22 one by one, which is also time-consuming.

[12] After the installation is completed, many works are conducted on the ceiling. As such, the worker is exposed to various accidents. The ceiling hanger hinders safe work, and thus doubles the working time.

[13] Recently, a variety of one-touch type fasteners have been developed for the ceiling hanger, thereby enabling temporal compensation and improvement of a fastening method. However, these ceiling hangers are manufactured by complicated and expensive processes, and furthermore are stilled exposed to the safety problem.

[14] Also, the ceiling hangers provide a weak fixing force and a poor decorative effect, thereby requiring various extra ceiling works such as installation, correction, maintenance and the like. Furthermore, the ceiling hangers make it difficult to be disassembled after installation, thereby deteriorating product quality and reliability. Disclosure of Invention Technical Problem

[15] The present invention has been made in an effort to solve the above problems, and it is an object to provide a ceiling hanger, in which a tight fixing means, which is fixed by a fastening socket in order to fasten a fixing support to an anchor bolt, is integrally formed with the fixing support according to shapes of members, such as carrying channels, lighting implements, air conditioners, etc., installed in various ceiling spaces, thereby ensuring simple installation and preventing the members from being separated therefrom.

[16] Another object of the present invention is to provide a ceiling hanger, which overcomes difficulty in construction when a fixing support is fastened to an anchor bolt, thereby compensating for temporal loss and improving a fixing force.

[17] Another object of the present invention is to provide a ceiling hanger, in which a fixing support is formed into a one-piece by pressing without any sharp edge, thereby remarkably reducing a thickness thereof compared to a known ceiling hanger, and making treatment very easy during work.

[18] Another object of the present invention is to provide a ceiling hanger, which is simply fastened unlike an existing method having several fastening steps, is installed in a clean and fine manner without an exposed sharp edge, thereby facilitating the following work or maintenance work without being damaged when any work is carried out in the ceiling space in the future. Technical Solution

[19] In one aspect of the present invention, a ceiling hanger fastened to a lower end of an anchor bolt embedded or anchored in a concrete ceiling, includes: a fixing support having a connection part with a shape of a member suspended from the ceiling and with threads equal to those of the anchor bolt; and a coupling socket coming into close contact with the anchor bolt and having an inner diameter with a tolerance enough to be fitted with an outer diameter with which the threads of the fixing support is contacted, wherein the coupling socket moves up and down and firmly, tightly fixed to the anchor bolt so as to be free from separation of the ceiling- suspended member.

[20] In one aspect of the present invention, the connection part of the fixing support has some of the threads equal to those of the anchor bolt when being in close contact, or openings or dots (embossments) formed by pressing, so as to protrude toward the anchor bolt, the openings or dots being partial window type open incisions in the direction of load, so that a plurality of incision faces or protruding parts corresponding to the load of the ceiling- suspended object are caught by the threads of the anchor bolt.

[21] In one aspect of the present invention, the coupling socket is coupled using a stop bolt at an upper portion thereof so as to be prevented from being arisen and separated from the fixing support.

[22] In one aspect of the present invention, the fixing support has the connection parts, heights of which are equal to or different from each other, and the connection part includes first and second connection parts, lengths of which are different from each other, and the coupling socket is coupled to both or one of the first and second connection parts.

[23] In one aspect of the present invention, the channel part is open at one side thereof.

Further, the channel part is located outside the anchor bolt, and the channel part is formed in a circular or quadrilateral cross section.

[24] In one aspect of the present invention, the coupling socket has an inner diameter corresponding to a predetermined height, and the channel part includes at least one reinforcement beading.

Advantageous Effects

[25] The ceiling hanger of the present invention comprises a fastening means, which the fixing support comes into close contact with the anchor bolt and is then screwed to be free from separation in an easy and simple manner by the fastening socket, and a locking means, which easily inserts and couples the ceiling-suspended member such as a carrying channel so as to be free from separation, so that it makes it possible to fasten the fixing support to the anchor bolt in a simple, rapid and stable way, overcome difficulty in construction to reduce the time for construction, improve the fixing force, provide the clear appearance, to provide easy treatment without being damaged during working, and ensure correction and disassembly in a very simple and easy way.

Best Mode for Carrying Out the Invention [41] Exemplary embodiments of the present invention will now be described more fully with reference to the accompanying drawings so that those skilled in the art can easily make the invention after a reading of the following description. [42] The invention may however be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. [43] It should be appreciated that the accompanying drawings are schematic and are not shown accurately to scale. In the drawings, the dimensions and ratios of the components may be exaggerated or reduced for clarity and convenience. However, such dimensions are only illustrative but not limiting.

[44] Furthermore, the same reference numerals are used throughout the different drawings to designate the same or similar components.

[45] Referring to FIGS. 2 to 21, the ceiling hanger includes a fixing support 10 and a coupling socket 20, in which the fixing support 10 is simply coupled to an anchor bolt 30 by means of the coupling socket 20.

[46] The anchor bolt 30 is previously buried in a concrete ceiling, for example, by an anchoring operation, to fix various objects. The coupling socket 20 is fitted around the lower portion of the anchor bolt 30 to be vertically movable. The fixing support 10 has connection parts 11 and 12 and a channel part.

[47] As shown in FIGS. 17 to 21, the channel part 13 of the fixing support 10 can be previously pressed into various shapes according to the shape of ceiling-suspended members.

[48] As shown in FIGS. 4 and 5, the connection parts 11 and 12 have different lengths

Ll and L2 (or heights), and the coupling socket 20 is coupled to both or one of the first and second connection parts 11 and 12.

[49] The coupling socket 20 is provided with first and second coupling parts 25 and 26, in a shape corresponding to the first and second connection parts 11 and 12, so as to be coupled with the first and second connection parts 11 and 12.

[50] In the fixing support 10 tightly fitted and coupled to the anchor bolt 30 by the coupling socket 20, the connection parts 11 and 12 have threads conforming to the threads of the anchor bolt 30. This structure has the same effect as in the prior art shown in FIG. 1, in which the fixing support 1 is fitted between nuts 21 and 22 engaged with the anchor bolt 3, and also can enhance fixing force.

[51] One of the connection parts 11 and 12 of the fixing support 10, coupled to the anchor bolt 30, can be made to be shorter or longer than the other. That is, the connection parts 11 and 12 can have the same length or different lengths.

[52] As shown in FIGS. 17 to 21, only the first connection part 11 can be tightly fitted on the anchor bolt 30 and be coupled thereto by the coupling socket 20, thereby increasing applicability. Optionally, the connection part is coupled to an intermediate portion of the anchor bolt 30, which is extended down. This is advantageous in terms of applicability.

[53] In the first and second connection parts 11 and 12 of the fixing support 10 having the threads conforming to those of the anchor bolt 30, as shown in FIG. 10, the number of the threads of the connection parts 11 and 12 can be adjusted according to the weight of an object applied to the channel part 13 of the fixing support 10, so that part of the threads are formed. As shown in FIG. 11, openings or dots (embossments), which are partial window type open incisions in the direction of load, can be formed by pressing so as to protrude toward the anchor bolt 30, so that a plurality of incision faces or protruding parts corresponding to the load of the ceiling- suspended object can be caught by the threads of the anchor bolt 30.

[54] As shown in FIG. 4, the size of the coupling socket 20 is determined from the circumferential dimension in the position where the connection parts 11 and 12 of the fixing support 10 are tightly fitted to the anchor bolt 30. The circumferential dimension is produced by adding the thickness of the fixing support 10 to the outside diameter of the threads of the anchor bolt 30.

[55] The coupling socket 20 has an upper portion 21 and a lower portion 22 of different diameters, and in the longitudinal direction thereof, has the first and second coupling parts 25 and 26, which extend in the same length as the first and second connection parts 11 and 12 of the fixing support 10.

[56] The coupling socket 20 is not formed of threads or the like in the inner circumference thereof, so as to easily move up and down on the outer circumference of the connection parts 11 and 12.

[57] Accordingly, the coupling socket 20 is firstly fitted on the anchor bolt 30, the first and second connection parts 11 and 12 of the fixing support 10 are tightly fitted on the lower portion of the anchor bolt 30, and then, as shown in FIG. 16, the socket 20 is moved down to fit on the first and second connection parts 11 and 12 of the fixing support 10, so that the coupling operation is accomplished.

[58] While the coupling socket 20 cannot move up against the law of gravity unless it is driven up by the hand so that the fixing support 10 can be separated from the anchor bolt 30, a stopper bolt 202 shown in FIG. 9 can also be provided for the purpose of safety.

[59] The second connection part 12 of the fixing support 10 can be separated from the anchor bolt 30 when the coupling socket 20 is moved up beyond the second connection part 12. When the coupling socket 20 is moved up beyond the first connection part 11, the fixing support 10 can be completely separated from the anchor bolt 30. In this position, the fixing support 10 can be freely attached to or detached from the anchor bolt 30.

[60] Accordingly, since the ceiling hanger can be easily handled by an operator, construction time can be reduced. The ceiling hanger can also have a good appearance and look better to remarkably improve the quality and reliability of a product.

[61] The fixing support 10 is a one-piece structure, and is manufactured by pressing a steel sheet so as not to have a sharp edge. The thickness of the steel sheet can be greatly reduced, thereby making the operation very easy.

[62] Unlike the conventional coupling technique including several steps, the ceiling hanger of the invention can be mounted by a single operation. Furthermore, the ceiling hanger has an aesthetic appearance and looks clean without an outwardly protruding edge, so that follow-up or maintenance operation inside the ceiling can be easily performed without problems such as injury.

[63] As shown in FIG. 2, the fixing support 10 is coupled using the coupling socket 20 instead of the fastening nuts of the conventional art. The connection parts 11 and 12 of the fixing support 10 are formed by pressing so as to conform to the threads of the anchor bolt 30, as shown in FIG. 5. The connection parts 11 and 12 are tightly fitted to the lower portion of the anchor bolt 30 shown in FIG. 12, and then the coupling socket 20 is moved down, thereby accomplishing the coupling operation.

[64] That is, the coupling socket 20 prevents the connection parts 11 and 12 of the fixing support 10 from escaping from the anchor bolt 30, thereby ensuring perfect coupling.

[65] For this, in the invention, the anchor bolt 30 is extended down from an anchor nut, which is previously buried, optionally by a separate anchoring operation, in the concrete ceiling, and the fixing support 10 is fixed to the lower end of the anchor bolt 30 in order to hold various objects. The coupling socket 20 of FIG. 12 is firstly fitted on the anchor bolt 30, the connection parts 11 and 12 of the fixing support 10 are tightly fitted on the anchor bolt 30, and then the coupling socket 20 is moved down, thereby fixing the fixing support 10.

[66] The fixing support 10 is manufactured as follows:

[67] The connection parts 11 and 12 of the fixing support 10 are formed as one unitary piece by pressing. As shown in FIG. 6, the connection parts 11 and 12 conform to the threads of the anchor bolt 30, and have a shape similar to a semicircle. The channel part 13 is formed between the connection parts 11 and 12, and can be manufactured according to the shape of objects, which the fixing support 10 will hold.

[68] According to the weight that the connection parts 11 and 12 of the fixing support 10 sustain, part of the threads can be omitted or be modified. As shown in FIG. 11, the openings or dots, which are partial window type open incisions in the direction of load, can be formed by pressing so as to protrude toward the anchor bolt 30, so that a plurality of incision faces or protruding parts corresponding to the load of the ceiling- suspended object can be caught by the threads of the anchor bolt 30.

[69] As shown in FIG. 7, the channel part 13 has one or more reinforcing beadings 14.

[70] The first connection part 11 is longer than the second connection part 12 of the fixing support 10 as shown in FIG. 4, so that the first connection part 11 can be firstly fitted on the anchor bolt 30 and be coupled in response to driving down the coupling socket 20. As shown in FIG. 14, after the insertion of a carrying channel 50, the second connection part 12 is fitted on the anchor bolt 30 and is coupled thereto by the coupling socket 20.

[71] As shown in FIG. 2, the coupling socket 20 is manufactured with a size regarding the circumferential dimension in the position where the connection parts 11 and 12 of the fixing support 10 are tightly fitted to the anchor bolt 30, that is, the thickness of the fixing support 10 added to the outside diameter of the threads of the anchor bolt 30. Accordingly, the coupling socket 20 can be easily moved up and down.

[72] When the first and second connection parts 11 and 12 of the fixing support 10 are fitted on the anchor bolt 30, the coupling socket 20 is moved down to fit on the first and second connection parts 11 and 12 as shown in FIG. 16, thereby accomplishing the coupling. When the coupling socket 20 is moved up beyond the second connection part 12 of the fixing support 10, the second connection part 12 can be separated from the anchor bolt 30. When the coupling socket 20 is moved up beyond the first connection part 11 of the fixing support 10, the fixing support 10 can be separated from the anchor bolt 30, thereby facilitating coupling and decoupling operations.

[73] Now, an operation of holding the carrying channel 50 will be described with reference to FIGS. 12 to 16.

[74] As shown in FIGS. 12 and 13, the first connection part 11 of the fixing support 10 is coupled to a desired position of the lower portion of the anchor bolt 30 by moving down the coupling socket 2.

[75] As shown in FIG. 14, the carrying channel 50 is inserted into the fixing support 10, in which the second connection part 12 is not coupled.

[76] As shown in FIGS. 15 and 16, the coupling socket 20 is moved up beyond the second connection part 12 of the fixing support 10, the second connection part 12 is fitted on the anchor bolt 30, and the socket 20 is moved down, thereby accomplishing the coupling operation.

[77] The coupling operation is improved as described above, the construction can be made easily and simply, thereby reducing construction time, improving fixing force, and maintain power balance.

[78] As shown in FIGS. 17 to 21, various configurations of fixing supports 1OA, 1OB,

1OC, 1OD and 1OE can be formed. Of these configurations, in the fixing support 1OA, 1OD and 1OE, the channel part is open at one side.

[79] The channel part of the fixing supports 1OD and 1OE is formed outside the anchor bolt 30.

[80] The channel part of the fixing supports 1OA, 1OB, 1OC, 1OD and 1OE can have a circular or quadrilateral cross section. These configurations are determined according to the shape of the ceiling- suspended members.

[81] The ceiling hanger of the invention has excellent machinability since it uses thinner materials than the conventional fixing support. The ceiling hanger of the invention can also enhance supporting ability, improve quality, and greatly improve reliability, stability and safety. [82] Although exemplary embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and/or modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will still fall within the spirit and scope of the present invention, as defined in the appended claims.
