Description

Belt holder for tape measure

[0001] The present invention relates to a belt holder, and more particularly, to a tape measure belt holder for hanging a tape measure while mounted on a belt.

[0002] Tape measures are widely used on construction sites because they allow for easy measurement of length and are also very portable.

[0003] Since tape measures are frequently used on construction sites, they are carried hanging from a belt. To facilitate this, tape measures are equipped with a belt clip.

[0004] A typical tape measure belt holder consists of a holder body that attaches to a belt and a holder with vertically-oriented clip holes for the tape measure to pass through. This type of standard tape measure belt holder allows the worker to hold the tape measure by hooking the tape measure's belt clip to the holder, freeing both hands. The tape measure can be conveniently removed from the holder whenever needed.

[0005] However, if a tape measure is placed using a tape measure belt holder in this way, there is a problem in that the tape measure can easily become separated from the tape measure belt holder when the worker moves excessively.

[0006] Therefore, a tape measure belt holder is required that, after attaching the tape measure to the belt holder, locks the tape measure to the belt holder so that the tape measure cannot be separated, and releases the lock only when necessary to separate the tape measure from the belt holder.

[0007] Meanwhile, US 11,517,103 has been presented as a prior art, and the prior art is deemed to be incorporated into this specification.

[0008] The present invention has been devised to solve the problems of the prior art as described above, and aims to provide a belt holder for a tape measure having a new structure in which the locking jaw of the locking bracket can be easily switched between a locked state and an unlocked state by operating a push button.

[0009] In order to solve the above problem, the present invention provides a tape measure belt holder including a holder body and a clip holder coupled to the front of the holder body and having a clip penetration hole formed vertically through which a belt clip of a tape measure passes, wherein: a locking bracket having a locking protrusion formed on the lower side to prevent the belt clip of the tape measure from coming off the clip penetration hole, a rotational axis formed on the upper side to be rotatably coupled to the holder body, and a rotational force input part formed on the inner side, and capable of rotating about the rotational axis such that when a rotational force is input to the rotational force input part, the locking protrusion moves from a position where it does not prevent the belt clip from coming off to a position where it prevents the belt clip from coming off; a bracket spring provided on the holder body and elastically supporting the locking bracket in one direction such that the locking protrusion of the locking bracket is positioned at a position where it does not prevent the belt clip from coming off; A push button having a push input portion formed at the top, a one-way rotation induction groove in the shape of a closed curve formed at the center in the vertical direction, and guided by the holder body to be able to reciprocate up and down so as to apply rotational force to the rotational force input portion of the lock bracket by moving downward and not input rotational force to the rotational force input portion of the lock bracket by moving upward; a push button spring provided on the holder body to elastically support the push button upward; a position-maintaining pin including a vertical extension portion extending vertically, a first engaging end portion bent horizontally at a lower end of the vertical extension portion and inserted into and engaged with a pin engaging hole formed in the holder body, and a second engaging end portion bent horizontally at an upper end of the vertical extension portion and inserted into a one-way rotation induction groove of the push button; , and the one-way rotation induction groove includes a first mounting portion on which the second coupling end can be mounted, and a second mounting portion formed at a higher position than the first mounting portion and on which the second coupling end can be mounted;The second engaging end of the position-maintaining pin can be seated on the first seating portion or the second seating portion while rotating in one direction along the one-way rotation induction groove by the up-and-down movement of the push button;

[0010] In the above: the one-way rotation induction groove further includes a first movement limiting portion formed on one side in the width direction at a higher position than the second seating portion to limit an upper movement range of the second engaging end portion, and a second movement limiting portion formed on the other side in the width direction at a higher position than the second seating portion to limit an upper movement range of the second engaging end portion; the second engaging end portion located in the first seating portion moves to the first movement limiting portion by the downward movement of the push button, the second engaging end portion located in the first movement limiting portion moves to the second seating portion by the upward movement of the push button, the second engaging end portion located in the second seating portion moves to the second movement limiting portion by the downward movement of the push button, and the second engaging end portion located in the second movement limiting portion moves to the first seating portion by the upward movement of the push button, so that the second engaging end portion can rotate in one direction along the one-way rotation induction groove; This is desirable.

[0011] In the above: the one-way rotation induction groove is formed between an inner guide wall extending in a closed curve shape and an outer guide wall extending in a closed curve shape and arranged to surround the inner guide wall; the inner guide wall includes a first inner guide surface guiding the second engaging end in one width direction when the second engaging end located in the first seating portion moves to the first movement restriction portion, and a second inner guide surface guiding the second engaging end in the other width direction when the second engaging end located in the first movement restriction portion moves to the second seating portion, and having the second seating portion connected thereto at the bottom; The above outer guide wall preferably includes a first outer guide surface that guides the second engaging end in the other width direction when the second engaging end moves toward the first movement restriction portion after passing the first inner guide surface, a second outer guide surface that guides the second engaging end in the other width direction when the second engaging end located at the second settling portion moves toward the second movement restriction portion while connecting the second engaging end at the upper portion, and a third outer guide surface that guides the second engaging end in the one width direction when the second engaging end located at the second settling portion moves toward the first settling portion while connecting the first settling portion at the lower portion;

[0012] As described above, the present invention allows the locking jaw of the locking bracket to be easily switched between a locked state and an unlocked state by operating the push button.

[0034] Below, with reference to the attached drawings, embodiments of the present invention are described in detail so that those skilled in the art can easily implement them. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, irrelevant parts have been omitted for clarity of description, and similar reference numerals have been assigned to similar parts throughout the specification.

[0035] Throughout the specification, whenever a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise stated.

[0036] A tape measure belt holder according to one embodiment of the present invention is intended to be able to hold a conventional tape measure equipped with a belt clip.

[0037] This belt holder for a tape measure includes a holder body (100), a locking bracket (200), a spring for the bracket (300), a push button (400), a spring for the push button (500), a pin for maintaining position (600), etc.

[0038] A belt connection part (110) for mounting on a belt is provided on the rear of the holder body (100) (see FIGS. 2 and 3). The belt connection part (110) can be used in a variety of forms.

[0039] A clip holder (120) is coupled to the front of the holder body (100), and a clip penetration hole (121) is formed in the vertical direction between the holder body (100) and the clip holder (120) (see FIG. 1 and FIG. 16).

[0040] The clip holder (120) is manufactured separately from the holder body (100) and is bolted to the holder body (100).

[0041] Therefore, when the belt clip of the tape measure is inserted vertically downward from the top of the clip penetration hole (121), the tape measure is mounted on the holder body (100).

[0042] A pair of elastic fixing pieces (130) in the form of a plate spring are provided on the front of the holder body (100).

[0043] A pair of elastic fixing pieces (130) are positioned inside the clip penetration hole (121) to hold and fix the belt clip inserted into the clip penetration hole (121) on both left and right sides of the belt clip (see Fig. 14).

[0044] For the description of the belt joint (110), grip holder (120), elastic fixing piece (130), etc. described above, reference is made to US 11,517,103 incorporated herein, and a detailed description thereof is omitted.

[0045] The holder body (100) has a structure in which a front body part (101) and a rear body part (102) are assembled together to form an empty space inside (see FIGS. 4 and 5).

[0046] A locking bracket (200) is attached to the front body part (101), and a pair of openings (101a) are formed in the front body part (101) for the locking bracket (200) to pass through.

[0047] On the rear side of the front body (101), an axis coupling portion (101b) is formed to couple the rotation axis (220) of the locking bracket (200) described later.

[0048] A pin coupling hole (102a) is formed in the rear body part (102) to allow the first coupling end (611) of the position-maintaining pin (600) described later to be coupled thereto.

[0049] A spring support jaw (102b) is formed on the front of the rear body (102) to support the lower part of the spring (500) for the push button.

[0050] A push button protection wall (102c) is formed to protrude upward on the upper part of the rear body (102) to prevent the push button (400) described later from being pressed unintentionally.

[0051] An opening (103) for a push button (400) is formed on the upper surface of the holder body (100) to guide the up and down movement of the push button.

[0052] The opening (103) for the push button is formed by combining the front body part (101) and the rear body part (102), and is located in front of the push button protection wall (102c).

[0053] The lock bracket (200) includes a locking jaw (210), a rotation shaft (220), a rotational force input portion (230), and a first spring coupling portion (240).

[0054] The locking jaw (210) is formed on the lower side of the locking bracket (200) to prevent the belt clip of the ruler from coming off from the clip penetration hole (121), and in this embodiment, two of them are formed.

[0055] The rotation axis (220) is formed on the upper side of the lock bracket (200) and is a portion that is rotatably connected to the shaft coupling portion (101b) of the holder body (100).

[0056] The rotational force input portion (230) is a portion formed on the inside of the lock bracket (200) and is a portion that receives rotational force from the push button (400) described later.

[0057] The first spring coupling portion (240) is a portion where the bracket spring (300) described later is coupled.

[0058] When the push button (400) inputs rotational force to the rotational force input unit (230) of the lock bracket (200), the locking jaw (210) can rotate around the rotational axis (220) to move to a position that prevents the belt clip from being detached.

[0059] The spring (300) for the bracket has one end coupled to the holder body (100) and the other end coupled to the first spring coupling portion (240) of the locking bracket (200), so as to elastically support the locking bracket (200) in one direction so that the locking jaw (210) of the locking bracket (200) is positioned so as not to prevent the belt clip from being detached.

[0060] Therefore, if there is no external force, the locking jaw (210) of the locking bracket (200) is located at a position that does not prevent the belt clip from being detached due to the spring (300) for the bracket, and when the push button (400) inputs rotational force to the rotational force input unit (230) of the locking bracket (200), the locking jaw (210) moves to a position that prevents the belt clip from being detached.

[0061] As described above, the locking jaw (210) of the locking bracket (200) can be switched between a locked state and an unlocked state.

[0062] Here, the locked state means a state in which the locking jaw (210) of the locking bracket (200) has moved to a position that prevents the belt clip from being detached, and in this state, the belt clip cannot separate the tape inserted into the clip penetration hole (121) from the belt holder.

[0063] In addition, the unlocked state means a state in which the locking jaw (210) of the locking bracket (200) is moved to a position where it does not prevent the belt clip from being removed, and in this state, the belt clip of the tape measure can be inserted into the clip penetration hole (121) to mount the tape measure on the belt holder, or the belt clip of the tape measure inserted into the clip penetration hole (121) can be separated from the belt holder.

[0064] Figures 1 to 5, Figure 14, Figures 16 to 18 are drawings based on the unlocked state.

[0065] Figures 15, 19 to 21 are drawings based on the locked state.

[0066] A push button (400) is provided to apply or not apply rotational force to the lock bracket (200).

[0067] The push button (400) is guided to move up and down by the holder body (100) and is arranged to penetrate the push button opening (103) of the holder body (100).

[0068] The push button (400) applies rotational force to the rotational force input portion (230) of the locking bracket (200) by moving downward, and does not apply rotational force to the rotational force input portion (230) of the locking bracket (200) by moving upward.

[0069] The push button (400) has a push input portion (410) formed at the top, a groove (420) for inducing one-way rotation is formed at the center in the vertical direction, and a second spring coupling portion (430) is formed at the bottom.

[0070] The push input unit (410) is a portion that receives the user's push operation. In other words, the user's pressing force is input into the push input unit (410).

[0071] The groove (420) for inducing one-way rotation is a groove in the form of a closed curve, into which the second engaging end (612) of the position-maintaining pin (600) described later is inserted, thereby inducing the second engaging end (612) of the position-maintaining pin (600) to rotate in one direction according to the up-and-down movement of the push button (400). The groove (420) for inducing one-way rotation will be described later.

[0072] The second spring coupling portion (430) is a portion where the spring (500) for the push button described later is coupled.

[0073] The spring (500) for the push button is supported at its lower end by the spring support jaw (102b) of the holder body (100) to elastically support the push button (400) upward.

[0074] The position-maintaining pin (600) includes a vertical extension portion (610) extending vertically, a first coupling end portion (611) bent horizontally at the lower end of the vertical extension portion (610) and inserted into and coupled with a pin coupling hole (102a) of a holder body (100), and a second coupling end portion (612) bent horizontally at the upper end of the vertical extension portion (610) and inserted into a groove (420) for inducing one-way rotation of a push button (400).

[0075] Referring to Fig. 9, the one-way rotation induction groove (420) is described in detail.

[0076] A one-way rotation induction groove (420) is formed between an inner guide wall (421) and an outer guide wall (422) that are formed facing each other and spaced apart from each other.

[0077] Each of the inner guide wall (421) and the outer guide wall (422) extends in a closed curve shape, and the outer guide wall (422) is arranged to surround the inner guide wall (421).

[0078] The inner guide wall (421) includes a second fixing portion (421a), a first inner guide surface (421b), and a second inner guide surface (421c).

[0079] The outer guide wall (422) includes a first fixing portion (422a), a first movement restriction portion (422b), a second movement restriction portion (422c), a first outer guide surface (422d), a second outer guide surface (422e), and a third outer guide surface (422f).

[0080] The second connecting end (612) of the position maintaining pin (600) can be mounted on the first mounting portion (422a) or the second mounting portion (421a).

[0081] At this time, the second fixing portion (421a) is formed at a higher position than the first fixing portion (422a).

[0082] That is, by the up-and-down movement of the push button (400), the second engaging end (612) of the position-maintaining pin (600) can be rotated in one direction along the one-way rotation-inducing groove (420) and be seated on the first seating portion (422a) or the second seating portion (421a).

[0083] The state in which the second connecting end (612) of the position-maintaining pin (600) is seated on the first seating portion (422a) or the second seating portion (421a) is described respectively.

[0084] When the second connecting end (612) of the position-maintaining pin (600) is seated in the first seating portion (422a) of the outer guide wall (422), the upper end of the push button (400) is maintained at the upper position (La), and at this time, the locking jaw (210) of the locking bracket (200) is positioned at a position that does not prevent the belt clip from being detached, and is in an unlocked state.

[0085] As shown in FIGS. 16 to 18, the push button (400) moves upward and does not input rotational force to the rotational force input portion (230) of the locking bracket (200), and the locking jaw (210) of the locking bracket (200) is positioned at a position that does not prevent the belt clip from being detached due to the spring (300) for the bracket.

[0086] Therefore, the lock bracket (200) becomes in the same state as in Fig. 1.

[0087] On the other hand, when the second connecting end (612) of the position-maintaining pin (600) is seated in the second seating portion (421a) of the inner guide wall (421), the upper end of the push button (400) is maintained at the lower position (Lb), and at this time, the locking jaw (210) of the locking bracket (200) is positioned at a position that prevents the belt clip from being detached, thereby entering a locked state.

[0088] As shown in FIGS. 19 to 21, the push button (400) moves downward to input rotational force to the rotational force input unit (230) of the locking bracket (200), whereby the locking jaw (210) of the locking bracket (200) is positioned at a position to prevent the belt clip from being detached.

[0089] Accordingly, the lock bracket (200) becomes in a state as shown in Fig. 15.

[0090]

[0091] Next, the one-way rotation induction action of the one-way rotation induction groove (420) is described.

[0092] A first movement restriction part (422b) and a second movement restriction part (422c) are formed on both sides of the width direction of the outer guide wall (422).

[0093] The first movement restriction portion (422b) is formed on one side in the width direction at a higher position than the second fixing portion (421a) to restrict the upper movement range of the second connecting end portion (612).

[0094] The second movement restriction part (422c) is formed on the other side in the width direction at a higher position than the second fixing part (421a) to limit the upper movement range of the second connecting end part (612).

[0095] In this structure, the push button (400) moves downward by the user's operation, and in addition, when there is no external force, the push button (400) moves upward by the elastic force of the spring (500) for the push button.

[0096] As shown in Fig. 23, when the push button (400) is positioned at the upper position (La) and the second connecting end (612) is seated on the first fixing portion (422a), and the push button (400) is moved downward by the user's operation, the second connecting end (612) moves from the first fixing portion (422a) to the first movement restriction portion (422b), as shown in Fig. 24.

[0097] At this time, in the process of converting from Fig. 23 to Fig. 24, the first inner guide surface (421b) and the first outer guide surface (422d) are used.

[0098] The first inner guide surface (421b) guides the second coupling end (612) located at the first fixing portion (422a) in one direction in the width direction when the second coupling end (612) moves to the first movement restriction portion (422b). That is, the first inner guide surface (421b) is in a form that extends in one direction in the width direction while facing upward.

[0099] The first outer guide surface (422d) guides the second coupling end (612) in the other direction in the width direction when the second coupling end (612) passing the first inner guide surface (421b) moves toward the first movement restriction part (422b), and the first movement restriction part (422b) is connected to the upper portion thereof. In other words, the first outer guide surface (422d) is in a form that extends inward in the width direction while facing upward.

[0100] In this state, when the force applied to the push button (400) is removed, the push button (400) moves upward due to the elastic force of the spring (500) for the push button, and as shown in FIG. 25, the second connecting end (612) moves from the first movement limiting portion (422b) to the second fixing portion (421a).

[0101] At this time, the second inner guide surface (421c) is used in the process of converting from Fig. 24 to Fig. 25.

[0102] The second inner guide surface (421c) guides the second coupling end (612) located at the first movement restriction part (422b) in the other widthwise direction when it moves to the second fixing part (421a), and the second fixing part (421a) is connected to the lower portion thereof. In other words, the second inner guide surface (421c) is in a form that extends in the other widthwise direction while facing downward.

[0103] Accordingly, the push button (400) is positioned at the lower position (Lb) and the second connecting end (612) is seated on the second fixing portion (421a).

[0104] When the push button (400) is positioned at the lower position (La) and the second connecting end (612) is seated on the second fixing portion (421a), and the push button (400) moves downward by the user's operation, the second connecting end (612) moves from the second fixing portion (421a) to the second movement limiting portion (422c), as shown in FIG. 26.

[0105] At this time, the second outer guide surface (422e) is used in the process of converting from Fig. 25 to Fig. 26.

[0106] The second outer guide surface (422e) guides the second coupling end (612) located at the second mounting portion (421a) in the other width direction when it moves toward the second movement limiting portion (422c), and the second movement limiting portion (422c) is connected to the upper portion thereof. In other words, the second outer guide surface (422e) is in a form that extends toward the other width direction while facing upward.

[0107] In this state, when the force applied to the push button (400) is removed, the push button (400) moves upward due to the elastic force of the spring (500) for the push button, and as shown in FIG. 27, the second connecting end (612) moves from the second movement limiting portion (422c) to the first fixing portion (422a).

[0108] At this time, the third outer guide surface (422f) is used in the process of converting from Fig. 26 to Fig. 27.

[0109] The third outer guide surface (422f) guides the second coupling end (612) located at the second movement restriction part (422c) in one direction in the width direction when it moves to the first fixing part (422a), and the first fixing part (422a) is connected to the lower portion thereof. In other words, the third outer guide surface (422f) is in a form that extends in one direction in the width direction while facing downward.

[0110] By this, the push button (400) is again positioned at the upper position (La) and the second connecting end (612) is seated on the first seating portion (422a).

[0111] By repeating the operation of the push button (400) as described above, the locking jaw (210) of the locking bracket (200) is alternately positioned in a position that does not prevent the belt clip from being removed and a position that prevents the belt clip from being removed.

[0112] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that the present invention can be readily modified into other specific forms without altering the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. For example, each component described as a single entity may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined manner.

[0113] The scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.

[0114] The present invention can be used as a tape measure belt holder that can hang a tape measure while being attached to a belt.
