Description

The present disclosure relates to a lamp stand device, and more particularly to a lamp stand device for hanging and securing a lamp on an object to be secured, such as a table.

2. Description of the Related Art In recent years, lamp stand devices have been used to hang lamps during outdoor activities such as camping.
A conventional lamp stand device includes a clamp that is fixed to an object to be fixed, such as a camping table, a support rod connected to the clamp, and a hanging member attached to the support rod so that a lamp can be hung.
Conventional clamps commonly used in lamp stand devices are "horizontally U-shaped" and are fastened only to the top and bottom surfaces of a flat object (e.g., a folding table top), so thick metal is used as the clamp material to ensure high rigidity. Also, a complex structure is required to fasten the clamp to the object, resulting 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 have limited usability, and there has been a continuing demand for lighter clamps and for clamps that can be secured to objects using a simple structure.

One aspect of the present disclosure provides a lamp stand device that includes a clamp that is lightweight and stably secured to an object to be fixed.

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 attached to the support rod and on which the lamp is hung, and a clamp connected to the lower end of the support rod so as to be positioned below the hanging member and detachably attached to 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 so as to fix the object to the clamp by applying pressure to the underside of the object to be fixed.
The fastening member has a male thread formed along the length of the fastening member, and the underside of the clamp has a female threaded hole so that the male thread can be screwed into it, and the female thread of the clamp may have a thread width greater than the thread root width.
The hanging member may include a body extending in a direction perpendicular to the 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 connected to the support rod.
The fixing clip may be composed of a semi-ring-shaped upper fixing clip extending along the circumferential direction of the support rod, and a semi-ring-shaped lower fixing clip extending along the circumferential direction of the support rod 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 place by the inclined section.

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, thereby stably connecting the insert member to the support rod.
According to another aspect of the present disclosure, a lamp stand device 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.

Fig. 1 is a perspective view showing a lamp stand device according to an embodiment of the present disclosure, and 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.
Referring to FIGS. 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 the hooking member 20 to support the lamp L. The support rod 10 is connected to the clamp 100. The hooking 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. However, the shape of the support rod 10 is not limited to the above example.

The hanging member 20 is provided to hang the lamp L. 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 for 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. 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.

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 having a front portion 101, an upper portion 102, a lower portion 103, and two side walls 110. The clamp 100 also includes an accommodation space 100a therein for accommodating a portion of a table top T.

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 abuts against the side wall portion 110 and the top 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 102 and the lower surface 103 and are arranged at an inclination angle to each other, i.e., an angle of inclination corresponding to the angle of the corner of the table top T (90 degrees in this embodiment).
The accommodation space 100a is formed by an upper surface 102, a lower surface 103, and two side walls 110. The corners of a flat table top T are inserted into and accommodated in the accommodation space 100a.

The clamp 100 is configured to surround the top, bottom, and left and right sides of the corner of the table top T. In other words, the clamp 100 abuts against the table top T over a wide area, allowing it to be stably fixed to the table top T. Conventionally, the clamp 100 has been manufactured using a highly rigid metal to secure it to the table top T. However, according to this embodiment, even if the clamp 100 is manufactured using a material with a somewhat lower rigidity (e.g., plastic), it can still 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 rod 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 of the support rod 10 (see FIG. 6).

In this embodiment, the insert member 120 may be made of a metal material, and the body of the clamp 100 may be made of a plastic material and 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 passing through the upper surface 102 of the clamp 100. It is also possible for the insert member 120 to be inserted into the clamp 100 by passing through the lower surface 103 of the clamp 100.

The fastening member 130 secures the clamp 100 with the corners of the table top T clamped between the clamps 100. With the table top T clamped between the clamps 100, the upper surface of the table top T abuts against the upper surface 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 vertically and is screwed to the lower surface 103 of the clamp 100. The fastening member 130 can move vertically as the rotational motion switches to linear motion. That is, the fastening member 130 moves upward while rotating, penetrating the lower surface 103 of the clamp 100, and as it does so, it applies pressure to the lower surface of the table top T, thereby securing 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 .

The head 131 penetrates the lower surface 103 of the clamp 100 and comes into contact with the underside of the table top T, applying upward pressure to the table top T. The knob 132 has a larger volume than the head 131. A user can use the knob 132 to rotate the fastening member 130. Note that the sizes of the head 131 and the knob 132 are not limited to those shown in the drawings.
The extension 133 extends vertically 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 to penetrate the lower surface portion 103.
The extension 133 is formed with a male screw 134. The male screw 134 is formed to protrude from the extension 133 over the entire length thereof.
A female screw hole 104 is formed in the lower surface 103 of the clamp 100. The female screw hole 104 is formed to correspond to the male screw 134 of the fastening member 130. The male screw 134 is screwed into the female screw hole 104.

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 the upper part of the support rod 10. The hanging member 20 is coupled to the support rod 10 so as to be rotatable.
The hooking member 20 includes a body 21, a hooking groove 22 for hanging the lamp L, and elastically deformable fixing clips 23a and 23b for connecting to the support rod 10. When connected 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.

The body 21 has a tip end and a base end. A hooking groove 22 is formed at the tip end of the body 21. The lamp L is hung and fixed in the hooking groove 22. The hooking groove 22 has a circular hole so that the lamp L can be hung. The hooking groove 22 has an opening 22a. The opening 22a is formed at the tip end of the body 21 along the length direction from the hooking groove 22. A ring of the lamp L may be inserted through the opening 22a so that the lamp L is supported in the hooking groove 22.
The fixing clips 23 a and 23 b are formed at the base end of the body 21 so as to be connected to the support rod 10 .
The fixing clips 23a, 23b are formed in a semi-ring shape so as to extend circumferentially around the support rod 10 when connected to the support rod 10. The fixing clips 23a, 23b are made of an elastically deformable material, and when connected to the support rod 10, their elasticity and friction with the support rod 10 allow them to be fixed on the support rod 10 without slipping. For example, the fixing clips 23a, 23b may be made of plastic. Therefore, even when the lamp L is hung in the hanging groove 22, the hanging member 20 is unlikely to slide downward.

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

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

Fig. 6 is a schematic view showing a state in which the insert member and the support rod are coupled together in the lamp stand device shown in Fig. 1. Fig. 6 is 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 narrowed portion 11, an expanded portion 12, and an inclined portion 13.
The reduced tube portion 11 has an inner diameter D2 that is 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 that is 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.

The inclined portion 13 may be provided between the narrowed 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 narrowed 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 tube portion 12, and is fixed to the support rod 10 by being sandwiched between the inclined portion 13. 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.

Fig. 7 is a schematic view showing the coupling relationship between the clamp and the 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.

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 root 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 is less rigid than metal, the area where the male thread 134 and the female thread 104 come into contact can be increased, 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 skilled in the art to which the present invention pertains may make any number of modifications and variations without departing from the spirit and scope of the technical ideas of the invention as set forth in the claims.
