Description

Description TOOL HANGER

Technical Field

[I] The present invention relates to a tool hanger which is constructed to be fastened to a worker's belt for allowing the worker to hang tools after use and carrying them.

[2]

Background Art

[3] In general, workers at a construction site do their jobs, carrying a tool with them. In case of a tool with a small volume, they do their jobs, carrying the tool in a collection box manufactured according to the size of the tool. In case of a tool with a relatively large volume, they do their jobs, carrying the tool by hanging it a tool hanger. Repre¬ sentative tools that can be carried by hanging them on a tool hanger include a tacker, an air stapler, an electric drill and so on.

[4] In the drawings, FIG.1 is a perspective view showing a tool hanger according to the conventional art.

[5] The tool hanger 10 as illustrated in FIG.1 is well known in Korean Registered

Utility Model No.20-0300537 (Title of the Invention: Hook of Air Stapler). According to the well-known art, a holder 13 fixed to a worker's belt 1 and a bridge member fastened to a tool are included.

[6] The holder 13 is in a hook shape, a vertical portion 13V of the holder 13 is welded and fixed to a clip 13C, and the clip 13C is fastened to the worker's belt 1. To the tool, the bridge member is fastened. A loop or hole is formed on the bridge member. Thus, when the holder 13 is inserted into the loop or hole of the bridge member, the tool is suspended, hung on the holder 13.

[7] However, the thus-constructed hanger is fixed to be protruded outside the worker's belt, being welded and fixed to the clip. As the thus-constructed hanger is hit against an object, a generated shock is transferred to the worker's waist through the clip without buffering. There is a drawback that the worker gets injured by such a shock.

[8] A tool hanger developed to supplement this problem is illustrated in FIG.2.

[9] FIG.2 is a side view showing a tool hanger 20 according to the conventional art, in which a fixed part 27 is vertically protruded and fixed to the side of a clip 25 fastened to a worker's belt (1 of FIG.l).

[10] A through hole 27H is formed on the fixed part 27, and a holder 23 is rotatably fastened to the through hole 27H of the fixed part 27.

[I I] An vertical portion 23 V of the holder 23 having a hook shape is inserted and positioned into the through hole 27H of the fixed part 27, and two ridges 23S are positioned and fixed to upper and lower portions of the fixed part 27.

[12] Therefore, the holder 23 is positioned in the through hole 27H of the fixed part 27 by the two ridges 23S, and in this state, it is freely rotatable around the vertical portion 23V. Resultantly, if the holder 23 is hit against an object, the holder 23 rotates itself to buffer a shock to be transferred to the worker, thereby protecting the worker.

[13] However, such a tool hanger has the following problem.

[14] In the procedure of hanging a tool on the holder 23 or lifting up the hung tool and removing it, the fixed part 27 is protruded inside the holder 23, thus the tool is interfered by the fixed part 27. As illustrated in FIG.2, the free end of the holder is formed in a ball-like shape, which makes a tool interfered and stopped when hanging or removing it.

[15] Moreover, as shown in FIG.2, the fixed part 27 fixed to the clip 25 is constructed to rotate 360 degrees in an arrow direction around a rotational axis on the side of the clip 25. As the fixed part 27 rotates 360 degrees, the holder 23 also rotates 360 degrees along with the fixed part 27. According to such a rotation structure of the holder 23, when the worker hangs or removes a tool, the holder 23 hung on the tool rotates upward, which makes it more difficult to remove the tool from the holder 23.

[16] If the tool is frequently interfered in the procedure of hanging a tool on the tool hanger or removing it, the tool cannot be hung or removed quickly and accurately, thereby decreasing the working efficiency and putting the worker under stress due to interference with his or her job.

[17] Besides, since the holder freely rotates, as the holder rotates by the self- weight of a tool when moving the tool hung on the holder, the tool may hit against an object or the worker's leg

Disclosure of Invention Technical Problem

[18] Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a tool hanger which is constructed so as to buffer a shock since the holder rotates upon being hit against an external object, and quickly and accurately hangs or remove the tool by fundamentally eliminating un¬ necessary interferences when hanging or removing the tool.

[19]

Technical Solution

[20] In accordance with an aspect of the present invention, the above and other objects can be accomplished by the provision of a tool hanger, which is constructed to be fastened to a belt worn by a worker for hanging a tool thereon, comprising: a fastening portion whose one side contacts the belt and is fastened thereto, and which has an vertical hole formed in an upper direction formed on the bottom face and a plurality of horizontal holes formed on the other side communicating with the vertical hole; a holder whose upper end is inserted into the vertical hole and whose lower end is bent; an elastic element which is inserted into one of the horizontal holes for pressing side portions of the upper end of the holder disposed within the vertical hole; and a supporting element which is inserted into another one of the horizontal holes for rotatably supporting the holder by inserting an end portion into a groove formed along the circumference of the holder.

[21] Furthermore, a plurality of semispherical grooves corresponding to the elastic element is formed on the upper end of the holder of the present invention along the cir¬ cumference.

[22] Furthermore, the elastic element of the present invention is a compression coil spring, a bead conforming to the semispherical grooves being disposed inside the one of the horizontal holes, a bolt being fastened outside the one of the horizontal holes, and the elastic force of the compression coil spring being applied to a direction of conforming the bead to the semispherical grooves.

[23] Furthermore, the supporting element of the present invention is a bolt, an end portion thereof being inserted into the groove of the holder for rotatably supporting the holder.

[24] Furthermore, a step having an upper end diameter smaller than a lower end diameter is formed on the upper end of the holder of the present invention, the upper end diameter being the same as or smaller than that of the vertical hole, and the lower end diameter being the same as the weight of the bottom face of the fastening portion.

[25] Furthermore, either a clip or a ring of an closed structure is fixed to one side of the fastening portion.

[26] Furthermore, the bent hanger of the present invention becomes gradually smaller in diameter as it approaches an end portion opposite to the end portion inserted into the fastening portion.

[27] Furthermore, the holder of the present invention may be sheathed with an insulating material.

Advantageous Effects

[28] As explained above in detail, the tool hanger of the present invention has an advantage that it can prevent a worker from being injured by buffering a shock to be transferred to the worker since the holder rotates by the shock in the event of being hit against an object.

[29] Further, as a force greater than a restoration force of a coil spring should be applied in order to rotate the holder, the holder does not rotate freely. If the holder rotates freely, it is stopped against other objects or the tool hung on a loop is hit against the objects or the worker's leg when the worker is moving. However, in the present invention, such a problem is solved because the holder rotates by a force greater than a predetermined force. [30] Further, the tool hanger of the present invention has such a construction in which the outer side of a vertical portion and the outer side of a fastening portion are smoothly extended. Thus, there is no component causing interference when the worker hangs the tool on the holder or removing it from the holder, which makes it easier to hang or removing the tool.

Best Mode for Carrying Out the Invention [47] As well-known means in the best mode for carrying out the present invention, a tool hanger, which is constructed to be fastened to a belt worn by a worker for hanging a tool thereon, comprises: a fastening portion whose one side contacts the belt and is fastened thereto, and which has an vertical hole formed in an upper direction formed on the bottom face and a plurality of horizontal holes formed on the other side com¬ municating with the vertical hole; a holder whose upper end is inserted into the vertical hole and whose lower end is bent; an elastic element which is inserted into one of the horizontal holes for pressing side portions of the upper end of the holder disposed within the vertical hole; and a supporting element which is inserted into another one of the horizontal holes for rotatably supporting the holder by inserting an end portion into a groove formed along the circumference of the holder. Mode for the Invention

[48] Hereinafter, embodiments of the present invention will be described.

[49] (First Embodiment)

[50] In the drawings, FIG.3 is an exploded perspective view showing a tool hanger according to a first embodiment of the present invention. FIG.4 is a side cross sectional view of the tool hanger as illustrated in FIG.3. FIG.5 is a plane cross sectional view showing a pressure portion of the tool hanger as illustrated in FIG.3. FIG.6 is a schematic view showing a use state of the tool hanger as illustrated in FIG.3.

[51] As illustrated in FIGs.3 and 4, the tool hanger 100 comprises a fastening portion

110 fastened to a worker's belt 1, a holder 120 fastened to the bottom face of the fastening portion 110 and disposed downward, and an elastic element for controlling the rotation of the holder 120.

[52] The thus -constructed tool hanger will be described more concretely belowΛ As shown in FIG.3, a round vertical hole 111 is formed upward. A clip 113 is fixed to the back face of the fastening portion 110, and two horizontal holes 115a and 115b com¬ municating with the vertical hole 111 formed inside are formed on one of both sides of the fastening portion 110. Here, a female screw is formed on inner sides of the horizontal holes 115a and 115b.

[53] The holder 120 is inserted into the vertical hole 111. The holder 120 is divided into a vertical portion 121 of a hook shape and a loop 123 bent at a predetermined radius of curvature, and the vertical portion 121 of the holder 120 is inserted into the vertical hole 111 of the fastening portion 110. More preferably, the diameter of the loop 123 becomes gradually smaller as it goes to the free end thereof. Since the diameter of the loop 123 becomes smaller as it goes to the free end, a tacker as an example of a tool can be easily hung on the loop 123 or removed therefrom.

[54] Grooves 125a and 125b corresponding to the two horizontal holes 115a and 115b are formed on the vertical portion 121 of the holder 120 inserted into the vertical hole

111 of the fastening portion 110. One of the grooves is a circular groove 125a formed to a predetermined depth along the circumference of the vertical portion 121, and the other grooves are semispherical grooves 125b as shown in FIG.5. The semispherical grooves 125b are formed at three points at 90-degree intervals along the circumference of the vertical portion 121. Here, the semispherical groove 125b is the term employed to identify differences in shape with the circular groove 125 a. If the radius of a metal bead 130 is denoted by R and the depth of the semispherical grooves 125b is denoted by H, 0 < H < R.

[55] With the vertical portion 121 being inserted into the vertical hole 111 of the fastening portion 110, the circular groove 125a and the semispherical grooves 125b are disposed corresponding to the two horizontal holes 115a and 115b formed on the fastening portion 110. Here, the horizontal hole corresponding to the circular groove 125a is referred to as a 'first horizontal hole 115', and the horizontal hole corresponding to the semispherical grooves 125b is referred to as a 'second horizontal hole 115'.

[56] In such a construction, a first bolt 117a is inserted and fastened into the first horizontal hole 115a, and an end portion of the first bolt 117a is inserted and disposed in the circular groove 125a formed on the vertical portion 121. Since the first bolt 117a is inserted and disposed in the circular groove 125 a of the vertical portion 121, the vertical portion 121 is not drawn out because it is stopped against the first bolt 117a, being inserted into the vertical hole 111 of the fastening portion 110, and the holder 120 becomes rotatable 360 degrees along the circular groove 125a by the first bolt 117a.

[57] Meanwhile, the metal bead 130 and a compression coil spring 133 are disposed inside the second horizontal hole 115b, and the second bolt 117b is fastened to the second horizontal hole 115b. At this point, as the metal bead 130 is given a force to move inside the second horizontal hole 115b by an elastic restoring force of the compression coil spring 133, parts of the metal bead 130 are inserted into one of the semispherical grooves 125b of the vertical portion 121.

[58] With the metal bead 130 being inserted into one of the semispherical grooves 125b upon receipt of the elastic restoring force of the compression coil spring 133, if the holder 120 rotates, the metal bead 130 falls out from the semispherical groove 125b, and the metal bead 130 is inserted into the semispherical groove 125b corresponding thereto the moment it is disposed corresponding to the other semispherical grooves 125b.

[59] In this structure, in order for the holder 120 to be rotatable, a force at least greater than the elastic restoring force of the compression coil spring 133 should be applied to the holder 120. That is, the coil spring 133 needs to be further elastaically deformed and contacted by a greater force applied so that the metal bead can fall out from the semispherical groove 12.

[60] Meanwhile, regarding the position of the three semispherical grooves 125b formed on the vertical portion 121 of the holder 120, one of the semispherical groove 125 is formed corresponding to the second horizontal hole 115b, with the loop 123 of the holder 120 being protruded outward from the fastening portion 110, and the other two semispherical grooves 125b are formed at points of 90 degrees with respect to the one of the semispherical grooves 125b.

[61] In the thus-constructed tool hanger, more preferably, as shown in FIG.3, the bottom width W of the fastening portion 110 is the same as the diameter D of the vertical portion 121, and a step 129 is formed on the vertical portion 121 and inserted into the vertical hole 111 of the fastening portion 110. As the step 129 is formed on the vertical portion 121, the step 129 is interfered at the bottom face of the fastening portion 110 when the vertical portion 121 is inserted into the vertical groove 111 of the fastening portion 110, thereby enabling the outer side of the fastening portion 110 and the side portions of the vertical portion 121 to be smoothly extended.

[62] The operating relationship of the thus-constructed tool hanger and the procedure of hanging or removing a tool will be described below.

[63] The tool hanger 100 is fastened to the worker's belt 1 by using the clip 113 formed on the back face of the fastening portion 110. At this point, the clip 113 is fastened so that the loop 123 of the holder 120 can face outward from the worker.

[64] In this state, when the loop 123 of the holder 120 is stopped against an object to generate a shock, the loop 123 rotates by the shock. That is, if the shock is greater than the elastic restoring force of the compression coil spring 133, the metal bead 130 is pushed and falls out from the semispherical groove 125b as the metal bead 133 contracts the compression coil spring 133, and in this state, the holder 120 rotates. As the holder 120 rotates, the shock to be transferred to the worker is buffered.

[65] Meanwhile, as illustrated in FIG.6, when hanging a tool 101 on the loop 123 of the holder 120 or removing it therefrom, as the outer side of the fastening portion 110 and the side portions of the vertical portion 121 of the holder 120 are smoothly extended, an open portion of the loop 123 is fully opened without any segment closed by the fastening portion 110. Consequently, the worker can smoothly hang the tool on the loop 123 or remove the tool hung on the loop 123 without any interference with other components.

[66] Besides, in the tool hanger 100 of the present invention, the loop 123 may be covered with a rubber sheath. The sheath covered on the loop 123 prevents a scratch caused by friction between the loop 123 and the tool 101. In some cases, it is for preventing an electric shock to the worker which is caused by the tool driven by electric power.

[67]

[68] (Second Embodiment) [69] As compared to the first embodiment, except that a ring of an closed structure, instead of the clip of the first embodiment, is fastened to the fastening portion of the second embodiment, the other components of the second embodiment is the same as or similar to those of the first embodiment. Thus, the same or similar components are represented by the same or similar reference numerals as those used in the first embodiment, and a detailed description thereof will be omitted.

[70] In the drawings, FIG.7 is a side view showing a tool hanger according to a second embodiment of the present invention.

[71] As illustrated in FIG.7, a ring 113' of a closed structure is fastened to the back face of a fastening portion 110. The ring 113' is in a rectangular closed structure. As the worker's belt passes through the ring 113' and is disposed, the fastening portion 110 is fastened to the belt 1.

[72] Although the technical spirits of the tool hanger of the present invention has been disclosed with reference to the appended drawings, the descriptions of the most preferred embodiments in the present specification are only for illustrative purpose, not for limiting the present invention.

[73]
