Description

[Technical field]

[0001] The present disclosure relates to a lamp stand apparatus, and more particularly to a lamp stand apparatus for hanging and securing a lamp on a supporting object such as a table. [Background technology]

[0002] 2. Description of the Related Art In recent years, lamp stand devices have been used for hanging lamps during outdoor activities such as camping. A conventional lamp stand device includes a clamp that is fixed to an object such as a camping table, a support rod connected to the clamp, and a hanging member that is attached to the support rod so that a lamp can be hung on it. Conventional clamps often used in lamp stand devices are "horizontally U-shaped" and are fixed only to the top and bottom surfaces of a flat object (e.g., the top of a folding table), so thick metal is used as the material of the clamp to ensure high rigidity. Also, a complex structure is adopted to fix the clamp to the object, which results in problems such as high manufacturing costs and time (see, for example, Korean Patent Publication No. 10-2014-0140237). As such, clamps made from thick metal are limited in their usability, and there has been a continuing demand for lighter clamps and a demand for a clamp that can be secured to an object using a simple structure. Summary of the Invention [Problem to be solved by the invention]

[0003] One aspect of the present disclosure provides a lamp stand apparatus including a clamp that is lightweight and stably secured to an object to be secured thereto. [Means for solving the problem]

[0004] A lamp stand device according to one embodiment of the present disclosure is for hanging and fixing a lamp on a flat object to be fixed, and includes a support rod, a hanging member provided on the support rod and on which the lamp is hung, and a clamp connected to a lower end of the support rod so as to be positioned below the hanging member and detachably provided at a corner of the object to be fixed, and the clamp may be configured to surround the top, bottom, and left and right sides of the object to be fixed when attached to the object to be fixed. The clamp may include a front portion that is open so that the object to be fixed can be inserted, an upper surface portion and a lower surface portion that are arranged parallel to each other above and below the front portion, and two side wall portions that connect the upper surface portion and the lower surface portion and are inclined at a predetermined angle to each other. The clamp may include an insert member extending upward from the upper surface portion and inserted into the lower end of the support rod, and a fastening member that penetrates the lower surface portion in the vertical direction and is screwed in order to secure the fixed object to the clamp by applying pressure to the underside of the fixed object. The fastening member may have a male thread formed along the length of the fastening member, and an internally threaded hole may be formed in the underside of the clamp so that the male thread can be screwed into it, and the internal thread of the clamp may have a thread width greater than a thread root width. The hanging member may include a body extending in a direction perpendicular to a length of the support rod, a hanging groove formed at a tip end of the body in which the lamp is hung, and at least one fixing clip having elasticity and formed at a base end of the body to be coupled to the support rod. The fixing clip may be composed of a semi-ring-shaped upper fixing clip extending circumferentially around the support bar, and a semi-ring-shaped lower fixing clip extending circumferentially around the support bar in the opposite direction to the upper fixing clip. The lower end of the support rod into which the insert member is inserted has a reduced tube section having an inner diameter smaller than the outer diameter of the insert member, an expanded tube section having an inner diameter larger than the outer diameter of the insert member, and an inclined section connecting the reduced tube section and the expanded tube section, and the tip of the insert member inserted through the expanded tube section may be clamped and fixed in the inclined section. Effect of the Invention

[0005] According to one aspect of the present disclosure, a lamp stand device can be provided that can be stably fixed and can be manufactured using lightweight materials, since the clamp holds the side of the object to be fixed. According to another aspect of the present disclosure, it is possible to provide a lamp stand device in which an insert member is expanded and inserted into a support rod to be stably coupled. According to another aspect of the present disclosure, a lamp stand apparatus can be provided in which a clamp and a fastening member are stably coupled together regardless of the material of the clamp. According to a further aspect of the present disclosure, a lamp stand device can be provided in which a hook member is elastically and stably fixed to a support rod.

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Fig. 1 is a perspective view showing a lamp stand device according to an embodiment of the present disclosure, Fig. 2 is a perspective view showing a state in which the lamp stand device shown in Fig. 1 is coupled to an object to be fixed. 1 and 2, a lamp stand apparatus 1 according to an embodiment of the present disclosure includes a support rod 10, a hook member 20, and a clamp 100. The support rod 10 is connected to a hook member 20 to support the lamp L. The support rod 10 is connected to a clamp 100. The hook member 20 is connected to the upper end of the support rod 10, and the clamp 100 is connected to the lower end of the support rod 10. The support rod 10 extends in the vertical direction. In this embodiment, the support rod 10 has a hollow cylindrical shape. The shape of the support rod 10 is not limited to the above example.

[0009] The hanging member 20 is provided so that the lamp L can be hung thereon. The hanging member 20 is rotatably connected to the support rod 10. The clamp 100 is connected to the lower end of the support rod 10. The clamp 100 is fastened to a corner of the object T to be fixed. In this embodiment, the object T to be fixed is a folding table top T that is often used in outdoor activities such as camping, and the clamp 100 is fixed to the square, flat table top T. The clamp 100 may be connected to one corner of the table top T. Note that the object T to be fixed is not limited to the above example, and may be furniture of other shapes as long as the clamp 100 can be attached to it.

[0010] Fig. 3 is a perspective view showing a clamp in the lamp stand apparatus shown in Fig. 1. Fig. 4 is a cross-sectional view of the clamp in the lamp stand apparatus shown in Fig. 3. 3 and 4, a clamp 100 according to an embodiment of the present disclosure is configured to surround the top, bottom, left and right sides of a corner of an object T to be fixed. The clamp 100 includes a body. The body includes a front portion 101, an upper portion 102, a lower portion 103, and two side walls 110. The clamp 100 includes an accommodation space 100a inside for accommodating a part of a table top T.

[0011] The front portion 101 is open so that an object T to be fixed can be inserted. When the table top T is inserted into the interior of the clamp 100 (i.e., the accommodation space 100a) through the front portion 101 and then coupled to the clamp 100, it comes into contact with the side wall portion 110 and the top surface portion 102. The upper surface portion 102 and the lower surface portion 103 are disposed parallel to each other above and below the front surface portion 101. The upper surface portion 102 and the lower surface portion 103 have a predetermined thickness. The two side walls 110 connect the upper surface portion 102 and the lower surface portion 103, and are arranged in a state inclined to form a predetermined angle with respect to each other. That is, the two side walls 110 are arranged at an inclination angle corresponding to the angle of the corner of the table top T (90 degrees in this embodiment). The accommodation space 100a is defined by an upper surface portion 102, a lower surface portion 103, and two side walls 110. The corners of a top plate T of a flat table are inserted into and accommodated in the accommodation space 100a.

[0012] The clamp 100 is configured to surround the upper, lower, left and right side surfaces of a corner of the table top T. That is, the clamp 100 abuts against the table top T over a wide area, and can therefore be stably fixed to the table top T. Conventionally, the clamp 100 has been manufactured using a highly rigid metal for fixing to the table top T, but according to this embodiment, even if the clamp 100 is manufactured from a material with a somewhat lower rigidity (e.g., plastic), it can be stably fixed to the table top T. This allows the clamp 100 to be lighter than conventional clamps, and reduces manufacturing costs. The clamp 100 further includes an insert member 120 for coupling with the support bar 10 and a fastening member 130 for fixing to the table top T. The insert member 120 extends upward from the upper surface portion 102. The insert member 120 is formed of a hollow pipe, and is inserted into the lower end portion of the support rod 10 (see FIG. 6).

[0013] In this embodiment, the insert member 120 is made of a metal material, and the body of the clamp 100 is made of a plastic material, and may be manufactured by an insert injection method. However, the manufacturing method of the clamp 100 is not limited to the above example. The insert member 120 may be inserted into the clamp 100 by penetrating the upper surface portion 102 of the clamp 100. It is also possible for the insert member 120 to be inserted into the clamp 100 by penetrating the lower surface portion 103 of the clamp 100.

[0014] The fastening member 130 fixes the clamp 100 in a state where the corners of the table top T are clamped by the clamp 100. With the table top T clamped by the clamp 100, the upper surface of the table top T abuts against the upper surface portion 102 of the clamp 100, and the lower surface of the table top T abuts against the fastening member 130. The fastening member 130 extends in the vertical direction and is screwed to the lower surface portion 103 of the clamp 100. The fastening member 130 can move in the vertical direction as the rotational motion switches to linear motion. That is, the fastening member 130 moves upward while rotating through the lower surface portion 103 of the clamp 100, and presses the lower surface of the table top T to fix the table top T to the clamp 100. The fastener 130 includes a head 131 disposed at an upper end, a knob 132 disposed at a lower end, and an extension 133 extending between the head 131 and the knob 132 .

[0015] Head 131 penetrates underside portion 103 of clamp 100 and comes into contact with the underside of table top T, thereby applying upward pressure to table top T. Knob 132 has a larger volume than head 131. A user can use knob 132 to rotate fastening member 130. Note that the sizes of head 131 and knob 132 are not limited to those shown in the drawings. The extension 133 extends in the up-down direction between the head 131 and the knob 132. The extension direction of the extension 133 is the same as the length direction of the fastening member 130. The extension 133 is provided penetrating the lower surface portion 103. The extension portion 133 is formed with a male screw 134. The male screw 134 is formed to protrude from the extension portion 133 over the entire length thereof. An internally threaded hole 104 is formed in the lower surface portion 103 of the clamp 100. The internally threaded hole 104 is formed to correspond to the external thread 134 of the fastening member 130. The external thread 134 is screwed into the internally threaded hole 104.

[0016] Fig. 5 is an enlarged perspective view of a latch member in the lamp stand device shown in Fig. 1. Fig. 5 is an enlarged view of part A shown in Fig. 1. 5, a lamp L can be hung on the hanging member 20. The hanging member 20 is coupled to an upper portion of the support rod 10. The hanging member 20 is coupled to the support rod 10 so as to be freely rotatable. The hook member 20 includes a body 21, a hook groove 22 for hanging the lamp L, and elastically deformable fixing clips 23a, 23b for coupling with the support rod 10. When coupled to the support rod 10, the body 21 extends in a direction perpendicular to the length of the support rod 10. In this embodiment, the support rod 10 extends in the vertical direction, and the body 21 may extend in the left-right or front-back direction perpendicular to the vertical direction.

[0017] The body 21 has a tip end and a base end. A hook groove 22 is formed at the tip end of the body 21. The lamp L is hung and fixed in the hook groove 22. The hook groove 22 has a circular hole so that the lamp L can be hung. The hook groove 22 has an open portion 22a. The open portion 22a is formed at a tip end along the length direction of the body 21 from the hook groove 22. A ring of the lamp L may be inserted through the open portion 22a so that the lamp L is supported in the hook groove 22. Fixing clips 23 a, 23 b are formed at the base end of the body 21 to be coupled to the support rod 10 . The fixing clips 23a, 23b are formed in a half-ring shape so as to extend circumferentially around the support rod 10 when they are coupled to the support rod 10. The fixing clips 23a, 23b are made of an elastically deformable material, and when they are coupled to the support rod 10, they are fixed on the support rod 10 without slipping due to their elastic force and friction with the support rod 10. For example, the fixing clips 23a, 23b may be made of plastic. Therefore, even if the lamp L is hung in the hook groove 22, the hook member 20 is unlikely to slide downward.

[0018] The fixing clips 23a, 23b include an upper fixing clip 23a and a lower fixing clip 23b that are spaced apart from each other in the vertical direction. The upper fixing clip 23a is formed at an upper portion of the base end portion of the body 21. The upper fixing clip 23a circumferentially surrounds the support rod 10. For example, the upper fixing clip 23a extends along a clockwise direction when the lamp stand device 1 is viewed from above. The lower fixing clip 23b is formed at a lower part of the base end of the body 21. The lower fixing clip 23b circumferentially surrounds the support rod 10 in the opposite direction to the upper fixing clip 23a. For example, the lower fixing clip 23b extends along the counterclockwise direction when the lamp stand device 1 is viewed from above.

[0019] The hook member 20 can be attached to and detached from the support rod 10 by a twisting motion. For example, when attaching the hook member 20, the user positions the hook member 20 so that the upper fixing clip 23a and the lower fixing clip 23b are aligned in a direction substantially perpendicular to the longitudinal direction of the support rod 10, and then twists the hook member 20 90 degrees in the direction of the arrow X1 so that the fixing clips 23a and 23b are fitted onto the support rod 10. Conversely, when removing the hook member 20, the user twists the hook member 20 in the direction of the arrow X2 (e.g., rotates 90 degrees) so that the fixing clips 23a and 23b are separated from the support rod 10.

[0020] Fig. 6 is a schematic diagram showing a state in which an insert member and a support rod are coupled in the lamp stand device shown in Fig. 1. Fig. 6 shows an enlarged view of part B shown in Fig. 1. 6, the insert member 120 is inserted into the lower end of the support rod 10 and coupled to the support rod 10. The lower end of the support rod 10 into which the insert member 120 is inserted includes a reduced portion 11, an expanded portion 12, and an inclined portion 13. The reduced tube portion 11 has an inner diameter D2 smaller than the outer diameter D1 of the insert member 120. Therefore, the insert member 120 cannot be inserted into the reduced tube portion 11. The expanded tube portion 12 has an inner diameter D3 larger than the outer diameter D1 of the insert member 120. Therefore, the insert member 120 can be inserted into the expanded tube portion 12.

[0021] The inclined portion 13 may be provided between the contracted portion 11 and the expanded portion 12. The inclined portion 13 is provided with an inclination such that the diameter becomes smaller from the expanded portion 12 to the contracted portion 11. The diameter of the inclined portion 13 becomes smaller toward the top. The tip of the insert member 120 is inserted into the support rod 10 via the expanded portion 12, and is sandwiched between the inclined portion 13 and fixed to the support rod 10. Therefore, the insert member 120 and the support rod 10 are stably joined and fixed so as to be difficult to separate. An insert cap 121 is provided at the tip of the insert member 120. The insert cap 121 covers the upper end of the insert member 120.

[0022] Fig. 7 is a schematic diagram showing a coupling relationship between a clamp and a fastening member in the lamp stand device shown in Fig. 1. Fig. 7 shows an enlarged view of part C shown in Fig. 4. 7, the fastening member 130 according to this embodiment extends in the vertical direction. The fastening member 130 has an outer surface formed with a male thread 134 protruding in the radial direction. The clamp 100 has an internally threaded hole 104 formed therein to correspond to the external thread 134 of the fastening member 130. The internally threaded hole 104 is formed in the lower surface portion 103.

[0023] The female thread hole 104 of the clamp 100 is formed so that the width L1 of the thread 104a is larger than the width L2 of the thread valley 104b. As a result, even if the male thread 134 of the fastening member 130 is formed from metal and the clamp 100 is formed from a plastic material that has lower rigidity than metal, the contact area between the male thread 134 and the female thread 104 can be made larger, thereby reinforcing the rigidity of the clamp 100. Although specific embodiments have been illustrated and described above, the present invention is not limited to the above-described embodiments, and a person having ordinary skill in the art to which the present invention pertains can make a variety of modifications and variations without departing from the spirit and scope of the technical ideas of the invention as set forth in the claims.
