Description

Technical Field

[0001] This invention relates to the field of measuring tool technology, specifically to a measuring tape, and more particularly to a measuring tape having a protruding grip (hereinafter referred to as "protruding grip (3)") on a housing (1) and a tape (2) braking control (4.1) on the protruding grip (3). Background Technology

[0002] As a basic measuring tool, the efficiency of a measuring tape directly affects work safety and measurement accuracy. Currently, most measuring tapes on the market have their braking controls (such as locking buttons or sliders) located at the front or top of the housing. This layout disrupts the integrity of single-handed grip, typically requiring the user to remove at least one finger (e.g., thumb or index finger) from a stable grip position to operate the braking control (4.1). Regardless of which finger is removed, it interferes with grip stability and leads to operational fatigue, separating the "grip" from the "braking control" action, resulting in the following problems:

[0003] 1. Operation interruption: Frequent adjustments to hand posture are required during measurement, affecting the continuity of operation;

[0004] 2. Unstable grip: When working at heights, on slippery surfaces, or while wearing gloves, loosening the grip to operate the braking control components can easily cause the measuring tape to slip from the hand;

[0005] 3. Decreased accuracy: The line of sight needs to be shifted from the measurement point to the braking position, increasing the risk of reading errors.

[0006] Therefore, the industry urgently needs a tape measure structure that is easier to operate and more stable to hold. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] This invention aims to solve the problems of inconvenient braking operation and easy interference with grip stability of existing measuring tapes, and provides a measuring tape with a reasonable structure that allows users to control the tape braking by only the movement of the index finger while maintaining a completely stable grip posture.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A measuring tape includes a housing (1), a retractable measuring tape (2), and a braking mechanism for locking the measuring tape (2), characterized in that it further includes:

[0012] A protruding handle (3) is connected to the housing (1) and protrudes to one side, the protruding handle (3) forming a grip for the user to hold with one hand;

[0013] A braking control element (4.1) is disposed on the gripping surface of the convex handle (3) and operable to control the locking or releasing of the braking mechanism on the ruler (2);

[0014] When the user holds the protruding handle (3) with one hand, the brake control (4.1) is located within the natural reach area of ​​the index finger, which can reach and operate the brake control (4.1).

[0015] Furthermore, the operating direction of the braking control element (4.1) is along the natural force direction of the user's index finger in the gripping state.

[0016] Furthermore, the gripping surface of the convex handle (3) refers to the area naturally contacted by the fingertips of the other four fingers when the user holds it with one hand, excluding the bearing surface that is in contact with the base of the thumb and the web of the hand.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Compact structure and easy operation: By setting an independent protruding grip on the housing and precisely arranging the brake control component in the index finger operating area, a measuring tape with a reasonable structure and easy one-handed operation of the brake control component (4.1) is provided.

[0020] 2. Achieve truly efficient one-handed operation: While maintaining a firm grip with the thumb, middle finger, and other fingers, the user can control the braking action solely through the movement of the index finger. This design fundamentally solves the problem of conflict between the "grip" and "braking" actions in traditional measuring tapes.

[0021] 3. Excellent technical compatibility: The "protruding handle + index finger operation" layout protected by this invention can be adapted to various braking control structures such as triggers, buttons, levers, and sliders; the human-machine layout scheme can be adapted to various braking mechanisms such as mechanical and electromagnetic, and provides a unified physical platform for future integration of auxiliary functions.

[0027] 3 — Protruding shank

[0028] 4.1 — Braking Control Components Detailed Implementation

[0029] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0030] like Figure 1 As shown, the measuring tape provided by the present invention includes a housing (1), a measuring tape (2), and a braking mechanism for locking the measuring tape. The convex handle (3) is connected to one side of the housing (1) and protrudes significantly outward. Its shape is ergonomically designed to form a grip for the user to hold with one hand.

[0031] The braking control element (4.1) is disposed on the gripping surface of the convex handle (3). The "gripping surface" here is specifically defined as the area naturally covered by the fingertips of the other four fingers (index finger, middle finger, ring finger, and little finger) when the user holds the convex handle (3) with one hand, excluding the bearing surface for support and pressure that is in contact with the base of the thumb and the web of the hand.

[0032] Since the index finger has good independent operability and force application efficiency when gripping, the present invention arranges the braking control element (4.1) in the natural touch area of ​​the index finger.

[0033] like Figure 1 and Figure 2 As shown, the braking control element (4.1) is located within the natural reach area of ​​the index finger. Figure 2 It demonstrates that when the user holds the device, the index finger can naturally reach and operate the brake control (4.1), while the thumb and other fingers maintain a stable grip posture without any adjustment.

[0034] In one example of a layout that implements the present invention, the brake control element (4.1) may be a trigger structure. A corresponding space may be formed inside the cam (3) to accommodate at least a portion of the brake control element and its pivot point, and it is connected to the brake mechanism in the housing (1) through a transmission component, so that the snapping action of the index finger can control the locking and releasing of the ruler (2).

[0035] In other embodiments, the braking control element (4.1) may also take the form of a lever, a push button, or a sliding slider.

[0036] Those skilled in the art should understand that the specific internal mechanical structure for realizing the core layout of "the index finger operating the brake on the convex handle" is not a limitation of this invention, and various existing or innovative transmission methods can be adopted.

[0037] The convex shank (3) can be integrally injection molded with the housing (1) to improve structural strength and sealing; it can also be used as an independent component and fixed or detachably connected by screws, buckles or other means.

[0038] It is understood that the scope of protection of this invention is not limited to the above embodiments. Any modifications, equivalent substitutions, and improvements made to the specific shape of the cam, the specific type of the brake control element, and its placement position within the spirit and principles defined by the claims of this invention shall be included within the scope of protection of this invention.
