Description

[Technical field]

[0001] The present invention relates to an improved hinge assembly, and more particularly to an improved hinge assembly which comprises a hinge rotating body and a hinge support, and which not only facilitates hinge rotation by the action of the hinge rotating body and the hinge support being hingedly rotated relative to each other, but also allows the hinge rotating body and the hinge support to easily return to their original positions by further pushing one of the hinge rotating body and the hinge support after the hinge rotation. [Background technology]

[0002] In general, a hinge device rotates around a fixed body, i.e., a fixed body, as a hinge to support an object, and is folded to move or store the object. Such hinge devices are used in a variety of applications, such as dining tables, chairs, tables, desks, outdoor tables, folding work tables, mobile work tables, as well as folding legged ironing boards, folding hangers, wall-mounted folding dining tables, wall-mounted folding beds, mobile sales counter table legs, mobile tables, collapsible exercise equipment, folding product display stands, sinks, display cabinet doors, bicycle or kickboard support means, folding means for extending or folding the length of a broomstick, and folding means for automobile seats.

[0003] As an example, in the folding device of the folding implement of Registered Utility Model No. 20-0322624, in a folding structure in which one or more folding operating tables are attached to a fixed body and are folded at a right angle, when one or more folding operating tables that function to rotate at a right angle in one direction are attached to the fixed body, a locking protrusion is protruded from one side and connected to a support piece with a binding pin, and a hook adjustment table that hooks and releases at a right angle to the locking protrusion of the support piece on one side of the folding operating table allows the folding implement to be folded and unfolded, and at this time, when folding, a spring is compressed, and when unfolding, the compressed elastic restoring body returns to its original position, allowing the folding implement to be easily unfolded. As another example, the folding bicycle with an auxiliary steering device of Registered Utility Model No. 20-0358061 has an auxiliary steering device that is composed of an operating bar attached to the rear of the folding bicycle and rotated by the operation of a handle, a first operating link connected to the operating bar by a connecting plate and moving horizontally by the rotation of the operating bar, and a second operating link connected to the first operating link by a spring and moving forward and backward by the operation of the first operating link and rotating the steering shaft to control the direction of the front wheel, and the auxiliary steering device is configured to be foldable, making it easy to store. In other words, the auxiliary steering device is folded and unfolded by the elasticity of the spring, improving space utilization during storage.

[0004] However, such conventional techniques have problems in that the structure is complicated, and the assembly time is increased, resulting in reduced ease of assembly and reduced productivity.

[0005] In addition, there is a problem that the number of components increases production costs and purchase or installation costs are burdensome. Therefore, there is an urgent need to develop a technology that can increase assembly and productivity with a simple configuration, reduce costs, firmly support the supported object, and allow the rotating body to be easily folded and unfolded relative to the fixed body.

[0007] The present invention aims to provide an improved hinge assembly comprising a hinge rotation body and a hinge support, which not only allows easy hinge rotation, but also allows the hinge rotation body and the hinge support to be fixed by a locking action in a rotated state, and allows the hinge rotation body and the hinge support to be unlocked and returned to their original positions by further pushing either the hinge rotation body or the hinge support. As a means for achieving the above object, the improved hinge assembly of the present invention is a hinge assembly comprising a hinge rotation body, a hinge support hingedly connected to the hinge rotation body, and a locking device provided on the hinge rotation body, in which when the hinge rotation body is hingedly rotated towards the hinge support, one side of the locking device is pressed while the other side is lifted, locking the hinge rotation body and the hinge support to maintain the rotated state, and when the hinge rotation body and the hinge support are locked, the locking device is released when the hinge support is pulled from the hinge rotation body, and when the locking device is released, the hinge rotation body is spread out from the hinge support and the hinge rotation body is returned to its original position. Effect of the Invention

[0008] In the present invention, the hinge rotation body and the hinge support are hinged to each other, and a locking device is provided on the hinge rotation body, and when the hinge rotation body and the hinge support are hinged, the locking device performs a seesaw motion in the left and right directions to lock the hinge rotation body and the hinge support, thereby fixing the rotated state.

[0010] Other objects and features of the present invention will become apparent from the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0011] Unless otherwise defined, all terms used herein, including technical and scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention pertains. Terms defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning they have in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense unless expressly defined in this application.

[0012] Hereinafter, an improved hinge assembly according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

[0013] As shown in the drawings, the present invention relates to a hinge assembly 100 including a hinge rotation body 110, a hinge support 120 hingedly connected to the hinge rotation body 110, and a locking member 118 provided on the hinge rotation body 110. When the hinge rotation body 110 of the present invention is hingedly rotated toward the hinge support 120, one side of the locking member 118 is pressed and the other side is lifted, so that the hinge rotation body 110 and the hinge support 120 are locked and maintained in a rotated state.

[0014] In addition, when the hinge support 120 is pulled from the hinge rotation body 110 in a state where the hinge rotation body 110 and the hinge support 120 are locked, the lock of the locking member 118 is released, and when the lock is released, the hinge rotation body 110 is spread from the hinge support 120 and the hinge rotation body 110 returns to its original position. In this manner, when the hinge rotation body 110 is spread from the hinge support 120 as shown in Fig. 5, the hinge rotation body 110 and the hinge support 120 maintain a vertical state with respect to each other at an angle of 180 degrees, and when the hinge rotation body 110 is hinge-rotated toward the hinge support 120 as shown in Fig. 6, the hinge rotation body 110 and the hinge support 120 are folded at an angle of 90 degrees and the hinge rotation body 110 is positioned horizontally with respect to the vertical direction of the hinge support 120. Also, when the hinge rotation body 110 is positioned horizontally with respect to the vertical direction of the hinge support 120, the hinge rotation body 110 positioned horizontally is fixed by the locking member 118 as shown in FIG.

[0015] In addition, when the vertical hinge support 120 is spread further away from the hinge rotation body 110 while the hinge rotation body 110 is fixed in the horizontal direction, the lock of the locking member 118 is released as shown in FIG. 7. At this time, when the hinge rotation body 110 is spread in the opposite direction to the direction in which it is folded toward the hinge support 120, the hinge rotation body 110 and the hinge support 120 are spread apart. For this purpose, the hinge rotor 110 of the present invention includes a connection part 112 having a bolt connection part 111 at its lower end, a rotor hinge part 114 extending integrally from the upper end of the connection part 112 and having a hinge shaft hole 113 at its inner center, a fastener accommodating part 116 provided on one side of the rotor hinge part 114 and having support grooves 115 at both ends, the fastener 118 is accommodated in the fastener accommodating part 116, fastener shafts 117 seated in the support grooves 115 are provided at both ends of the fastener 118, and the fastener shafts 117 allow the fastener 118 to make a seesaw movement in the left and right directions. Also, a seesaw guide surface 119 is provided on the lower surface of the locking member 118, which is inclined upward toward the upper surface of the locking member 118 in both directions centered on a locking member axis 117 provided on both ends of the locking member 118 so that the seesaw movement of the locking member 118 can be easily performed. Also, the hinge support 120 is composed of a first hinge support 120a and a second hinge support 120b which are positioned facing each other and bolted together, and are hinge-connected to both sides of the rotor hinge part 114 of the hinge rotor 110, respectively.The first hinge support 120a includes a first rotation support part 121 having a first rotation support hole 121a that is in close contact with one surface of the rotor hinge part 114 of the hinge rotor 110 and is positioned to correspond to one side of the hinge shaft hole 113, a first hook 122 extending from an outer surface of the first rotation support part 121, a first semi-spiral part 123 provided at an end of the first hinge support 120a and spirally coupled to a supported object, a locking ball receiving guide 124 formed on the inner side of the first rotation support part 121 and having a long groove, and a locking ball receiving guide 124 that is received in the locking ball receiving guide 124 so that the hinge rotor 110 faces the hinge support 120. When the hinge is rotated and folded, the locking ball 125 moves toward the locking member 118 and presses one side of the locking member 118 so that the other side of the locking member 118 is lifted and locked, and when the hinge rotation body 110 is pressed further toward the hinge support 120 so that the hinge rotation body 110 is folded further toward the hinge support 120, the locking ball 125 moves to the other side of the locking member 118 and presses the lifted other side of the locking member 118 so that the lock is released. And when the other side of the locking member 118 is lifted while one side is pressed by the locking ball 125, the locking ball 125 engages with the lifted other side of the locking member 118. In addition, the second hinge support 120b includes a second rotation support part 127 having a second rotation support hole 127a that is in close contact with the other surface of the rotor hinge part 114 of the hinge rotor 110 and is positioned to correspond to the other side of the hinge shaft hole 113, a second hook 128 that extends from the outer surface of the second rotation support part 127 and is in close contact with the first hook 122 of the first hinge support 120a, and a second semi-spiral part 129 that is provided at the end of the second hinge support 120b, is in close contact with the first semi-spiral part 123, and is spirally coupled to the supported object. It also includes a hinge shaft hole 113 that connects the hinge rotation body 110 to the first rotation support hole 121a of the first hinge support 120a and the second rotation support hole 127a of the second hinge support 120b, and a fastening bolt 140 that fastens and fixes the first hinge support 120a and the second hinge support 120b.The first hinge support 120a and the second hinge support 120b of the hinge support body 120 are arranged symmetrically to each other, and the first rotation support portion 121 of the first hinge support 120a is closely attached to one side of the rotor hinge portion 114 of the hinge rotor 110, and the second rotation support portion 127 of the second hinge support 120b is closely attached to the other side of the rotor hinge portion 114 of the hinge rotor 110. In this state, the first hinge support 120a and the second hinge support 120b are fastened together by fastening the fastening bolt 140.

[0016] As shown in Figures 5 to 8, the locking device 118 is arranged inside the locking device receiving portion 116 so as to perform a seesaw action in both directions, i.e., left and right directions, centered on the locking device shaft 117. As shown in Figure 6, when the right side of the locking device 118 is pressed centered on the locking device shaft 117, the left side of the locking device 118 is lifted, and when the right side of the locking device 118 is pressed as shown in Figure 7, the left side of the locking device 118 is lifted. The reason why the locking device 118 can perform the seesaw motion is that the locking device shafts 117 provided at both ends of the locking device 118 are fitted and seated in the support grooves 115 provided at both ends of the locking device receiving portion 116, so that the locking device 118 can be raised and lowered in the left and right directions in the drawing as shown in the figure around the locking device shafts 117. At this time, this is possible because the hinge support body 120 and the hinge rotation body 110 which form the hinge assembly 100 are hingedly rotated relative to each other by the locking ball 125. In addition, since the seesaw guide surface 119 is provided on the underside of the locking member 118, the seesaw guide surface 119 is positioned in an upwardly raised state in the inner space of the locking member receiving portion 116, and thus, with the center of the underside of the locking member 118 in contact with the bottom surface of the locking member receiving portion 116, the seesaw guide surfaces 119 provided on both sides of the locking member shaft 117 are lowered or raised to the left or right, so that the seesaw motion of the locking member 118 can be easily performed. In addition, one side of the upper surface of the locking member 118 is provided with a moving guide surface 119a that is inclined downward so that the locking ball 125 can easily move toward the locking member 118. Since the moving guide surface 119a is inclined downward as shown in the figure, when the locking ball 125 moves toward the right side of the locking member 118, the locking ball 125 can be prevented from getting caught on one side end of the locking member 118, and the locking ball 125 can easily move toward the right side of the locking member 118 and press the right side of the locking member 118.

[0017] In the present invention thus constructed, when the hinge rotor 110 is positioned vertically with respect to the hinge support 120 as shown in Fig. 5, the locking ball 125 is positioned away from the locking member 118. When the hinge rotor 110 is hinge-rotated around the hinge shaft hole 113 as an axis and folded toward the hinge support 120 as shown in Fig. 6 with the locking ball 125 being away from the locking member 118, the first rotation support part 121 of the first hinge support 120a moves in the opposite direction to the rotating hinge rotor 110, and the locking ball 125 moves to the right side of the locking member 118 due to the rotation of the first rotation support part 121, so that the locking ball 125 is positioned at the upper right end of the locking member 118, and the right side of the locking member 118 is pushed by the load of the locking ball 125 positioned to the right side of the locking member 118. In addition, when the right side of the locking member 118 is pressed by the load of the locking ball 125 being transmitted due to the movement of the locking ball 125, the left side of the locking member 118 is lifted around the locking member shaft 117, and the lifted left side of the locking member 118 engages with the locking protrusion 126 of the first rotation support part 121. In this manner, when the left side of the locking member 118 is lifted and engages with the locking protrusion 126, it is locked, and the hinge rotation body 110 positioned horizontally with respect to the vertical direction of the hinge support body 120 is locked and fixed. 7, when the hinge support 120 is spread backward with respect to the hinge rotation body 110, the locking ball 125 located on the right side of the locking member 118 moves toward the left side of the locking member 118 and presses the left side of the locking member 118, at which time the left side of the locking member 118 is pressed and the right side of the locking member 118 is lifted, and the left side of the locking member 118 is released from the locking protrusion 126. When the hinge rotation body 110, which is positioned horizontally, is pulled away from the hinge support 120 with the locking member 118 released from the locking protrusion 126, the hinge rotation body 110 and the hinge support 120 are positioned vertically with respect to each other as shown in FIG.

[0018] At this time, since the locking ball receiving guide 124 in which the locking ball 125 is received is formed as a long groove as shown in the figure, the locking ball 125 can move at a predetermined interval inside the locking ball receiving guide 124. As a result, the locking ball 125 moves to the other side of the locking member 118 and the other side of the locking member 118 is pushed by the load of the locking ball 125, so that the engagement with the locking protrusion 126 is easily released. The second hinge support 120b of the hinge support 120 of the present invention is provided with a return body receiving portion 151, a return body fitting groove 152 extending to the upper side of the return body receiving portion 151, and a return body support protrusion 153 on one side of the return body fitting groove 152. The elastic return body 150 is received in the return body receiving portion 151 and closely contacts the other side of the rotating body hinge part 114 of the hinge rotating body 110, and one end 150a is fitted and engaged in the return body fitting groove 152, and then supported by the return body support protrusion 153. In addition, the other side of the rotating body hinge part 114 of the hinge rotating body 110 is provided with a return body locking groove 154 in which the other end 150b of the elastic return body 150 is engaged. The elastic return body 150 is of course not limited to any particular one, and is preferably configured as a spring such as a coil spring or a strain spring that allows the hinge rotation body 110 to be quickly opened by its own elastic force when the hinge rotation body 110 is opened from the hinge support 120 after the hinge rotation body 110 is rotated and folded relative to the hinge support 120. As described above, by providing the elastic return body 150, when the hinge rotation body 110 is rotated and folded relative to the hinge support 120, the elastic return body 150 is compressed and the hinge rotation body 110 is unfolded from the hinge support 120, the unfolding operation of the unfolded hinge rotation body 110 is accelerated by the elastic return force of the compressed elastic return body 150, so that the locking ball 125, which has been moved toward the other side of the locking member 118 and pressed the other side of the locking member 118 to be released from the locking member 118, can be quickly moved toward one side of the locking member 118, i.e., toward the right side in the drawing, and the hinge rotation body 110 can be quickly unfolded from the hinge support 120, so that the locking can be quickly released.

[0019] As described above, the present invention has been described using specific details such as specific components and limited embodiments and drawings, but these are merely provided to allow a more general understanding of the present invention, and the present invention is not limited to the above embodiments, and a person having ordinary knowledge in the technical field to which the present invention belongs can make various modifications and variations from such descriptions. Therefore, the idea of ​​the present invention should not be limited to the described embodiments, and all things equivalent to the claims or equivalent modifications, not only the claims described below, but also those that fall within the scope of the idea of ​​the present invention.
