Description

Table frame assembly

Technical Field

The present invention relates to a table frame assembly forming a table by supporting an upper plate disposed at an upper portion and using a joint formed by combining a plurality of frame members with each other, and more particularly, to a table frame assembly forming a joint by fastening a first frame member and a second frame member, each formed of a tubular member, to a third frame member with fasteners, thereby facilitating assembly and having a strong combination property.

Background

In general, a table is a structure used as an office table and office furniture, a dining table, a display rack, and the like, and is composed of an upper plate for placing objects and a frame assembly for supporting the upper plate.

Wherein the frame assembly utilizes a coupling portion formed by coupling the length members to each other, the firm coupling of the coupling portion may play an important role in the stability of the entire table. Wood may be used as a length member of such a frame assembly, but recently, a metal material is used more frequently in order to improve supporting force and durability, and wood, synthetic resin, glass, etc. may be used as the upper plate.

As described above, when a metal material is used as the length member of the frame assembly, at least a part of the metal material is to be used as a tubular member having a square or circular uniform cross section, wherein a welded structure or a manner of reinforcing by attaching a frame member between a plurality of frame members is adopted in order to form a firm joint.

However, when the joint is formed by welding in whole or in part, a strong joint can be obtained, but a separate welding jig is required, which causes a cost, and there are drawbacks in that the thermal deformation during welding causes problems such as warpage and dimensional change, and weld marks cause problems in that the external appearance is deteriorated.

In addition, the method of reinforcing the frame members by adding the frame members between the frame members requires additional processing of the existing frame members, and the additional frame members increase the material cost and the working time of the fastening work, and the fastening structure is complicated, which is problematic.

Therefore, there is a need for a technique that can form a firm joint without using welding, and that can provide a simple joint structure by which an operator can easily perform the assembly work of the table frame.

As shown in fig. 1 to 15, the table frame assembly 100 of the present invention includes a joint portion a formed by joining a plurality of

frame members

10, 20, 30 to each other, and supports an upper plate 1 disposed at an upper portion to form a table. Generally, a square table frame assembly utilizing four joints a may be formed, for example, a triangular table frame assembly utilizing three joints a or a polygonal table frame assembly utilizing five or more joints a may be formed as desired. As shown in fig. 1 (b), the table frame assembly 100 and the upper plate 1 may be combined with each other by fastening screws 2 to form a table, but the table frame assembly is not limited to this fastening structure, and other fastening structures may be used as needed. The upper plate 1 may be appropriately sized and arranged on the upper portion of the table assembly 100 as needed.

In one embodiment of the present invention, the joint a of the table-frame assembly 100 is substantially formed by joining the first frame member 10, the second frame member 20, and the third frame member 30 to each other as shown in fig. 2. In fig. 1 and 2, the first frame member 10 and the second frame member 20 are horizontally arranged to function as a support frame for supporting the upper plate 1 on the upper portion, and the third frame member 30 is vertically arranged to function as a leg frame, but the present invention is not limited thereto as will be described later. That is, the first frame member 10 and the second frame member 20, and the third frame member 30 are not limited to members having a specific function, and should be construed broadly as specific structures forming the joint portion a of the table-frame assembly 100.

In one embodiment of the present invention, the first frame member 10 and the second frame member 20 of the joint a of the table-frame assembly 100 are both formed of tubular members to be joined with the third frame member 30, thereby forming the joint a, and in order to improve the structural rigidity of these joint portions, an insert reinforcing bracket 40, which will be described later, is inserted into the distal end portion for fixing the

holes

11, 12 of the insert reinforcing bracket 40 by means of the pin members 60; 21 As shown in fig. 3 (a), the first frame member 10 and the second frame member 20 are provided at the distal end portions thereof facing the joint portion a, respectively. Wherein the side surfaces of the two end parts of the pin member 60 are clamped in the

holes

11, 12;21 The reinforcing bracket 40 inserted into the first frame member 10 or the second frame member 20 is fixed by the insertion 22, and the outer shape thereof may be a screw shape or a bolt shape having a screw thread as required, in addition to a simple cylindrical shape or a square column shape. For example, the pin member may be in the shape of a screw or bolt having threads near the head.

As shown in fig. 4, the insertion reinforcing brackets 40, which are inserted into the distal ends of the first and

second frame members

10 and 20 and fixed by the pin members 60, have a first reinforcing wing 42 and a second reinforcing wing 43 extending parallel to each other from both ends of the center surface portion 41, and have a cross-sectional shape of '' as a whole. Wherein holes 44, 45 for disposing the pin member 60 are provided at positions opposite to each other in the first and

second reinforcement wings

42, 43, respectively, and the center face portion 41 has a coupling hole 46 to be fastened to the third frame member 30.

That is, as shown in the upper left side of fig. 5, the insertion reinforcing brackets 40 are inserted into the distal end portion of the first frame member 10 and fixed to the first frame member 10 by the pin members 60. In the same manner, the insertion reinforcing brackets 40 are inserted into the distal end portion of the second frame member 20 and fixed to the second frame member 20 by the pin members 60.

Next, as shown in fig. 3 (b), a third frame member 30 having a first through hole 31 formed therethrough in a first direction perpendicular to the longitudinal direction and a second through hole 32 formed therethrough in a second direction perpendicular to the longitudinal direction is prepared.

In a state where the prepared first frame member 10 is brought close to the third frame member 30 from the first direction of the third frame member 30, the fastener 70 is fastened to the coupling hole 46 of the insert reinforcing bracket 40 fixed to the distal end portion of the first frame member 10 through the first through hole 31 of the third frame member 30, thereby forming a structure in which the first frame member 10 is coupled to the first direction of the third frame member 30. Similarly, in a state where the prepared second frame member 20 is brought closer to the third frame member 30 from the second direction of the third frame member 30, the fastener 70 is fastened to the coupling hole 46 of the insert reinforcing bracket 40 fixed to the distal end portion of the second frame member 10 via the second through hole 32 of the third frame member 30, and the second frame member 20 is coupled to the second direction of the third frame member 30. By forming the joint a through this process, fig. 1 (a) shows a completed state of the table frame assembly 100 in which four corner portions form such joint a, and fig. 1 (b) exemplarily shows a structure in which the upper plate 1 is disposed at an upper portion of the table frame assembly 100 and fastened by the fastening screw 2.

As described above, the joining portion a is formed by the insertion reinforcing brackets 40 having the cross-sectional shape of '' as a whole, and therefore, the table frame assembly 100 having a convenient assembly and a strong joining force is formed by the insertion reinforcing brackets 40, the pin members 60, and the fasteners 70 without welding. That is, the insertion reinforcing bracket 40 provides a strong fastening force based on the fastener 70 while providing a strong coupling force based on the pin member 60 without being separated from the first frame member 10 or the second frame member 20. Wherein the first reinforcing wing part 42 and the second reinforcing wing part 43 extending in parallel with each other from the insertion reinforcing bracket 40 are supported by pins at a place above a predetermined depth in the first frame member 10 or the second frame member 20, so that the coupling part a of the present invention provides a strong coupling force exceeding the welding coupling in terms of tensile strength. As described above, the pin member 60 basically functions as a snap-in member that prevents only the detachment of the insert reinforcing bracket 40, and may have additional specific structures described below for the desired additional functions and effects.

In which the upper left side of fig. 5 shows that the center face portion 41 of the insertion reinforcing bracket 40 coincides with the terminal portion of the first frame member 10 or the second frame member 20, but is not limited thereto. That is, even when the center surface portion 41 of the insert reinforcing bracket 40 protrudes inward or outward from the terminal end portion of the first frame member 10 or the second frame member 20, the fastening force by the fastener 70 can be transmitted to the first frame member 10 or the second frame member 20 by the insert reinforcing bracket 40 and the pin member 60, and the basic function of preventing the first frame member 10 or the second frame member 20 from loosening or coming off at the joint portion a is achieved, so that the joint portion a of the present invention is effective.

The first reinforcing wing portion 42 and the second reinforcing wing portion 43 extending parallel to each other from the insertion reinforcing bracket 40 are inserted into the first frame member 10 or the second frame member 20 and disposed in the longitudinal direction thereof, and have an effect of supplementing the horizontal beam (beam) function of the first frame member 10 or the second frame member 20, and further improving the structural strength of the joint portion a.

In addition, in one embodiment of the present invention, the pin member 60 of the table frame assembly 100 may have a specific structure as follows to form a further enhanced coupling structure, in addition to being formed of a simple pin structure to prevent the insert reinforcing bracket 40 inserted into the inside of the first frame member 10 or the second frame member 20 from being separated. That is, as shown in the right side of fig. 5, the pin member 60 has a structure in which one end of a main body 61 has a head 62, a protruding screw 63 having an outer diameter protruding from the surface of the main body 61 is provided adjacent to the head 62, and a locking end 65 having an outer diameter smaller than that of the main body 61 is formed at the other end of the main body 61. The first reinforcing wing portion 42 and the second reinforcing wing portion 43 of the insert reinforcing bracket 40, which form a coupling structure corresponding to the pin member 60 of such a modified structure, are formed with the

holes

44, 45 respectively constituted by the pin fastening holes 44 and the pin through holes 45. Looking at a specific structure, the pin fastening hole 44 has an inner diameter larger than the outer diameter of the main body 61 of the pin member 60 and smaller than the outer diameter of the protruding screw 63 at the first reinforcement wing 42, and the pin through hole 45 has an inner diameter smaller than the outer diameter of the main body 61 of the pin member 60 and larger than the outer diameter of the engagement end 65 at the second reinforcement wing 43.

The process of constructing the joint portion a having the further reinforced joint structure using the pin member 60 and the insert reinforcing bracket 40 having such a specific structure is as follows.

First, the insert reinforcing bracket 40 is inserted into the distal end portion of the first frame member 10 such that the pin introduction hole 11 of the first frame member 10 coincides with the pin fastening hole 44 of the first reinforcing wing portion 42 of the insert reinforcing bracket 40, and at the opposite position, the pin through hole 45 of the second reinforcing wing portion 43 of the insert reinforcing bracket 40 and the pin engagement hole 22 of the first frame member 10 will be located at positions coinciding with each other in a concentric structure. In this state, when the pin member 60 is inserted from the pin terminal portion 66 into the pin introduction hole 11 of the first frame member 10 and advanced, the main body 61 of the pin member 60 freely passes through the pin fastening hole 44 and the protruding screw 63 is in a resistant state in which it cannot easily pass through the pin fastening hole 44, and at the opposite position, at least the engagement end portion 65 of the pin member 60 is inserted into the pin through hole 45.

At this time, when the pin member 60 is tightened by the tool P, the protruding screw 63 continues to move into the pin fastening hole 44, and the engagement end 65 of the pin member 60 is inserted into the pin engagement hole 12 of the first frame member 10 through the pin through hole 45, and the force pushing the second reinforcement wing 43 is continuously applied in a state where the main body 61 cannot be inserted into the pin through hole 45 and engaged. At this time, if the stepped portion 64 is formed at the boundary point between the main body 61 and the engagement end portion 65, the pin through hole 45 can form a mutually stable internal force acting structure in a state of being located at the stepped portion 64, and thus a further improved support structure can be provided.

In general, there is an effect of further spacing the distance between the first reinforcing wing 42 and the second reinforcing wing 43 of the insertion reinforcing bracket 40 in proportion to the progress of the insertion of the protruding thread 63. This allows the first reinforcing wing part 42 and the second reinforcing wing part 43 to be more closely attached to the inner wall of the first frame member 10, thereby providing a strong friction force, preventing the insertion reinforcing bracket (40) from being detached from the first frame member 10. The second frame member 20 insert-bonded to the insert-reinforcing bracket 40 is prepared in the same manner as the first frame member 10 insert-bonded to the insert-reinforcing bracket 40, and the prepared first and

second frame members

10 and 20 are fastened and bonded to the first and second through

holes

31 and 32 of the third frame member 30 by the fasteners 70 as described above, thereby constituting the bonded portion a having a further improved bonding relationship than the foregoing embodiment.

In the thus reinforced coupling structure, the first frame member 10 or the second frame member 20 and the insertion reinforcing bracket 40 have not only a simple pin joint structure but also a friction-based separation preventing structure, and the table frame assembly 100 constructed by the coupling portion a using the structure has not only a stronger structural strength but also a reinforced effect of minimizing loosening of a specific coupling portion even if the use time is increased.

In addition, in one embodiment of the present invention described above, in the table frame assembly, the third frame member 30 is not limited to the tubular member. That is, the first frame member 10 and the second frame member 20 are constituted by tubular members, but the third frame member 30 may be constituted by tubular hollow members as shown in fig. 2, or solid (solid) members as shown in fig. 6, as required.

When the third frame member 30 is formed of a tubular member, as shown in fig. 7 (b), the fastening structure by the fastener 70 can be reinforced by providing a fastening reinforcement bracket 50, which will be described later, inside the tubular third frame member 30 in addition to the simple structure of the joint portion a as shown in fig. 7 (a). Fig. 7 (b) shows a fastening and reinforcing bracket 50 having an 'l' -shaped cross section and formed with through

holes

51, 52 for fastening members 70, wherein in the process of joining the third frame member 30 to the first frame member 10 and the second frame member 20 by the fastening members 70, the fastening and reinforcing bracket 50 is inserted into the inside of the tubular third frame member 30 to be brought into close contact with the inner wall of the third frame member 30, and thereafter, the joining process by the fastening members 70 is performed, whereby a joining portion a having further improved structural strength is formed.

In one embodiment of the present invention, in the table-frame assembly 100, tool access holes 33, 34 for allowing the fastening tool P to enter and exit for applying the fastening force to the fastening member 70 are provided in the tubular third frame member 30 at positions corresponding to the first through hole 31 and the second through hole 32, respectively. That is, even if the tool access holes are not provided, as shown in fig. 8 (b), the fastening operation of the fastener 70 can be performed by the tool P1, but as shown in fig. 8 (a), the convenience of the fastening operation can be remarkably improved by providing the tool access holes 33, 34.

Further, after the tubular third frame member 30 is formed with the tool access holes 33, 34 to perform the assembling work of the table assembly, if the tool access holes 33, 34 are still opened, the appearance performance may be deteriorated, and foreign matters, insects, etc. may be entered, and if a child inserts a finger, etc. with curiosity, the child may be injured, so that as shown in fig. 2, etc., the fastening tool P is used to fasten the fastening member 70 through the tool access holes 33, 34, and then the tool access holes 33, 34 are blocked with the finishing cover member 80 capable of blocking the tool access holes 33, 34, thereby forming a coupling structure further improving the appearance performance.

In one embodiment of the present invention, as shown in fig. 2 and 7, the table-frame assembly 100 has further improved coupling performance when the

frame members

10, 20, 30 constituting the coupling portion a are square tubular members having the same cross-sectional dimensions to form the coupling portion a. That is, when the joint is formed by square tubular members having the same cross-sectional dimensions, the contact points are more located at the portions of the frame members having the material on the back surface than at the portions having the hollow back surface, and as a result, the joint is formed in such a structure that the forces distributed and transmitted in the joint are distributed more in the regions of the frame members having high material density, thereby improving the load transmission distribution structure of the joint and further improving the structural performance of the joint.

In addition, in one embodiment of the present invention, the first frame member 10 and the second frame member 20 are horizontally arranged to function as a supporting frame for supporting the upper plate 1 at the upper portion, and the third frame member 30 is vertically arranged to function as a leg frame, thereby forming a table frame assembly, but is not limited thereto. That is, for example, as shown in fig. 9 (b), the second frame member 20 and the third frame member 30 may be horizontally arranged to function as a support frame for supporting the upper plate 1 on the upper portion, and the first frame member 10 may be vertically arranged to function as a leg frame, thereby forming a table frame assembly.

In one embodiment of the present invention, the first reinforcing wing portion 42 and the second reinforcing wing portion 43 inserted into the reinforcing bracket 40 are inserted into the first frame member 10 and the second frame member 20 arranged horizontally in a posture of being positioned at the lower portion and the upper portion, respectively, and the pin member 60 is coupled upward from the lower portion to form a fixed structure, but the present invention is not limited thereto. That is, based on the posture of the pin member 60, a structure in which the pin member 60 is coupled downward from above, a structure in which the pin member 60 is coupled leftward from right, a structure in which the pin member 60 is coupled rightward from left, or the like may be selected as necessary.

In addition, in one embodiment of the present invention, the first reinforcing wing portion 42 and the second reinforcing wing portion 43 of the reinforcing bracket 40 are inserted into the tubular first frame member 10 or the second frame member 20 in a posture in which the first reinforcing wing portion 42 and the second reinforcing wing portion 43 face inward and the center surface portion 41 faces outward, and are fixed, but in a modified example, as shown in fig. 10 (b), the joining portion a is formed in a posture in which the center surface portion 41 of the reinforcing bracket 40 faces inward and the first reinforcing wing portion 42 and the second reinforcing wing portion 43 face outward, and are inserted into the tubular first frame member 10 or the second frame member 20 and are fixed, so that the table frame assembly 100 is constituted. In this case, the pin member 60 and the fastener 70 should not interfere with each other, and the specific structure should be appropriately changed by the arrangement in which at least one of the pin member 60 and the fastener 70 is moved laterally, and it is necessary to use a fastener 70 longer than that shown in fig. 10 (a).

In one embodiment of the present invention, the first frame member 10, the second frame member 20, and the third frame member 30 are formed of tubular members having square cross sections, but the present invention is not limited thereto. That is, the table frame assembly 100 may be formed by forming the first and

second frame members

10 and 20 from tubular members of circular cross section and forming the third frame member 30 from tubular members of square cross section as shown in fig. 11 (b), forming the connecting portion (a) from tubular members of square cross section and forming the first and

second frame members

10 and 20 from tubular members of circular cross section and forming the third frame member 30 from tubular members of circular cross section as shown in fig. 11c, or forming the connecting portion (a) from tubular members of circular cross section and forming the connecting portion (a) from tubular members of circular cross section, as shown in fig. 11d, wherein the insertion reinforcing brackets 40 and the fastening reinforcing brackets 50, the pin members 60 are prepared to conform to the respective cross section shapes.

Also, the table assembly 100 of the present invention is not limited by the order of assembly. That is, as described above, in addition to the manner in which the table is formed by first forming the table frame assembly 100 using the coupling portion a as shown in fig. 1 (a) and then coupling the upper plate 1 as shown in fig. 1 (b), the manner in which the table frame assembly and the table are simultaneously formed by first coupling a portion of the frame members forming the coupling portion a to the upper plate 1 and then coupling the remaining frame members forming the coupling portion a as shown in fig. 12 may be employed, and even if such an assembly order is changed, it should be interpreted as the table frame assembly 100 including the coupling portion a of the present invention. Further, as shown in fig. 12, when a reinforcing web bracket 91 is provided between the frame members and a member is added in addition to the member of the present invention, the table-frame assembly 100 of the present invention is considered to be a component including the member described in the claims of the present invention.

In addition, in one embodiment of the present invention, the pin member 60 constituting the coupling portion a of the table frame assembly 100 may additionally have a function of fixing the upper plate 1. That is, in one embodiment of the present invention, both end sides of the pin member 60 of the joint a of the table frame assembly 100 are engaged to the

holes

11, 12;21 The first frame member 10 or the second frame member 20 is basically inserted into the reinforcing bracket 40, and has a length up to a thickness at which the first frame member 10 or the second frame member 20 can be inserted into the upper plate 1, and is formed in a cylindrical shape as a whole, and as shown in fig. 13 (a), the reinforcing bracket is fastened to the upper plate 1 by having a terminal fastening portion 68 screwed to an end portion corresponding to the upper plate 1, and additionally has a function of fixing the upper plate 1. The other end portion of the pin member 60 has a structure necessary for operating the fastening operation tool, such as a polygonal head or a tool groove. As shown in fig. 13 (b) and (c), the pin member 60 may have a structure other than the terminal fastening portion 68 as needed, and is not limited to the specific structure shown in fig. 13.

As described above, the pin member 60 having the terminal fastening portion 68 is used to form the joint a of the table-frame assembly 100 as in the previously described embodiment illustrated in fig. 2 to 12, and has the advantageous effect of fixing other members such as the upper plate in addition to the function of forming the joint a.

Specifically, in this assembly mode, the pin member 60 for fixing the insertion reinforcing bracket 40 inserted into the distal end portion of the first frame member 10 or the second frame member 20 is prepared in a temporarily fixed state to form the table frame assembly 100 as shown in the right side view of fig. 14, the upper plate 1 is disposed on the table frame assembly 100, and then the pin member 60 is fastened to fasten the terminal fastening portion 68 to the upper plate 1, thereby forming the table as shown in the right side view of fig. 14. Further, in addition to this assembly, the assembly of the foregoing embodiment may be adopted, and the table frame assembly 100 of the present invention may be constructed by first fastening the first frame member 10 or the second frame member 20 of the joint a to the upper plate 1 by inserting the reinforcing brackets 40 and the pin members 60 and then combining the remaining members 30 of the joint a.

The table-frame assembly 100 and the table using the same according to the present invention are more organically coupled to each other as a whole because of the structure of fixing the upper plate 1 together by the pin members 60 constituting the coupling portion a, and the effect of simplifying the overall assembly structure and assembly work of the table, member management, etc., and thus have further improved strength and durability in terms of external force support and dispersion.

Also, in one embodiment of the present invention, the pin member 60 of the table frame assembly 100 may have the following specific structure to form a further raised coupling structure in addition to basically having a pin structure and having a terminal fastening portion to fix the upper plate to prevent the detachment of the insert reinforcing bracket 40 inserted into the inside of the first frame member 10 or the second frame member 20. That is, as shown on the right side of fig. 15, the pin member 60 has a head 62 at one end of a main body 61, a protruding screw 63 adjacent to the head 62 and having an outer diameter protruding from the surface of the main body 61, and a locking end 65 having an outer diameter smaller than that of the main body 61 is formed at the other end of the main body 61.

In the embodiment of fig. 5, etc. having the pin member 60 including the head 62 and the protruding screw 63, the locking end 65 as described above, in the coupling structure having such an additional structure, the first frame member 10 or the second frame member 20 and the insertion reinforcing bracket 40 have the anti-disengagement structure based on the friction force in addition to the simple pin structure, so that the table frame assembly 100 formed of the coupling portion a has a more firm structural rigidity and can minimize the reinforcing effect of the specific coupling portion becoming loose even if the use time is increased. The terminal fastening portion 68 of the pin member 60 has the excellent effect of significantly improving the durability, rigidity, and assembling property of the joint portion a.

In addition, the foregoing description of the present invention is provided for illustration only, and it should be understood by those having ordinary skill in the art of the present invention that it may be easily converted into other specific forms without changing the technical spirit or essential features of the present invention. The above embodiments are therefore illustrative in all respects, rather than restrictive.
