Abstract
A deceleration device of a tape rule is equipped with a speed reduction gear wheel in the tape rule housing. The speed reduction gear wheel is in mesh with a transmission gear wheel of a reel for coiling a measuring tape such that the rotational speed of the reel when retrieving the extended tape is retarded thereby preventing the danger of scratching the user's finger or damaging the tape itself by abrasion or impingement. Engagement of the speed reduction gear wheel and the transmission gear wheel can be released by operating a flat pusher plate provided on the housing.
Description
- 1. Field of the Invention
- The present invention relates to a deceleration device of a tape rule, in particular, a deceleration device equipped in a tape rule capable of retarding the retrieving speed of a tape so as to prevent damaging the tape or scratching the user's finger.
- 2. Description of the Prior Art
- A tape rule plays an important role in many fields of engineering for measuring size of an object.
- In an conventional tape rule, when retrieving the tape, the user turns a handle bar or a shank emerging out of the tape rule housing to rotate a reel accommodated therein and the tape is rewound around the reel. However, it is not ideal to rewind the tape manually with such a time consuming and tedious way. For overcoming the above shortcoming. There has appeared an automatic retrieving tape on the market, soon afterwards, it has been discovered that there are some new problems brought up by this new type of tape rule, namely:
- 1. Retrieving the tape with high speed accompanies the danger of scratching the user's finger due to vibration of the tape.
- 2. Impingement of the tape tip with high speed onto the housing is prone to damage the tape and shorten its lifetime.
- 3. Abrasion of high speed moving tape with the edge of housing causes of early wearing of the tape.
- In view of the foregoing situation, the inventor of the present invention has conducted intensive research based on many years of experience gained through professional engagement in the manufacturing of related products, with continuous experimentation and improvement culminating in the development of the ingenious deceleration device of a tape rule.
- It is an object of the present invention to provide a deceleration device of a tape rule capable of preventing the danger of scratching the user's finger with the high speed retrieving tape.
- It is another object of the present invention to provide a deceleration device of a tape rule capable of preventing the impringement of the high speed retrieving tape onto the tape rule housing causing damage to the tape tip.
- It is one more object of the present invention to provide a deceleration device of a tape rule with a simple structure, easy for assembling, and low production cost.
- To achieve these and other aforementioned objects, the deceleration device of the present invention comprises a tape rule housing, a reel, and a deceleration unit. Wherein a through hole for an axle is provided at the reel center portion and a transmission gear wheel is coaxially fitted into the reel. The housing is formed of an upper housing and a lower housing, and an axle is passing through the center portion of the upper housing. A speed reduction gear wheel of the deceleration unit is fitted in an aperture provided for the upper housing and in mesh with the transmission gear wheel of the reel such that the reel can rotate 360° about the axle to rewind the tape into the tape rule housing with a reduced speed thereby avoiding possible injury to the user or the tape rule itself.
- For fuller understanding of the nature and objects of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings in which:
- FIG. 1 is an exploded view of the deceleration device of a tape rule according to the present invention;
- FIG. 2 is a three dimensional view of the deceleration device of a tape rule according to the present invention;
- FIGS.3(A) and 3(B) are illustrative views showing the operation of the deceleration device according to the present invention;
- FIG. 4 is an exploded view of the deceleration device of a tape rule in another embodiment of the present invention;

tape rule housing 1; areel 2; and adeceleration unit 3. The tape rule housing is composed of anupper housing 12 and alower housing 11. Anaxle 121 is erected on the center portion of theupper housing 12 through acenter hole 22 of thereel 2, and atransmission gear wheel 21 is coaxially fitted to the real 2. By so thereel 2 can rotate about theaxle 121 in thehousing 1 to extend or retrieve ameasuring tape 4. Thetransmission gear wheel 21 is then covered with theupper housing 12. - The kernel of the
deceleration unit 3 is a speedreduction gear wheel 31 which has tappedholes - For assembling, the speed
reduction gear wheel 31 is set up in theupper housing 12 via anaperture 122 formed nearby theaxle 121, and is in mesh with thetransmission gear wheel 21 of thereel 2, thedeceleration unit 3 is engaged with theupper housing 12 on its outer surface thereof byscrews 5 after aligning the tappedholes deceleration units 3 with the corresponding tappedholes upper housing 12 respectively. - Meanwhile, the
deceleration unit 3 may be operated with oil pressure, or pneumatic pressure, or by other mechanical means. - Referring to FIGS.3(A) and 3(B), in which the operation principle of the deceleration device is illustrated. Since the
transmission gear wheel 21 for thereel 2 is in mesh with the speedreduction gear wheel 31 of thedeceleration unit 3, the rotational speed of thereel 2 is retarded by the speedreduction gear wheel 31 so that thetape 4 can be retrieved with a rather low speed thereby avoiding the collision of thetape tip 41 with thehousing 1 or abrasion of thetape surface 42 and prolonging the lifetime of the tape rule. - For understanding another embodiment of the present invention, reference should be made to FIGS. 4 and 5. The deceleration device in this embodiment comprises a
tape rule housing 6; areel 2; and adeceleration unit 7. Thetape rule housing 6 is composed of anupper housing 62 and alower housing 61. Anaxle 624 is erected on the center portion of theupper housing 62 through acenter hole 22 of thereel 2, and atransmission gear wheel 21 of thedeceleration unit 7 is coaxially fitted into thereel 2. By so the real 2 can rotate about theaxle 624 in thehousing 1 to extend or retrieve ameasuring tape 4. Thetransmission gear wheel 21 is then covered with theupper housing 62. - A
flat puser plate 74 with a plurality ofslip stop stripes 741 thereon is provided on the outer surface of thedeceleration unit 7, and a speedreduction gear wheel 71 is installed beneath its inner surface thereof. One terminal of thedeceleration unit 7 has a throughhole 72, while the other terminal thereof is formed into ahook 73. - For assembling, the speed
reduction gear wheel 71 is set up in theupper housing 62 via anaperture 621 whose size being slightly larger than that of the speedreduction gear wheel 71 and is in mesh with thetransmission gear wheel 21 of thereel 2. After aligning the throughhole 72 with acircular hole 622 provided on theupper housing 62, and penetrating ahinge pin 8 therethough, thedeceleration unit 7 may be hinged to the outer surface of theupper housing 62 and displaceable to and fro thereon by operating theflat pusher plate 74. Thehook 73 at one terminal of thedeceleration unit 7 is used to hook onto apost 623 provided on the outer surface of theupper housing 62 nearby theaperture 621 for fixing thedeceleration unit 7 stably at its position. - Meanwhile, the
deceleration unit 7 may be operated with oil pressure, or pneumatic pressure, or by other mechanical means. - Referring to FIGS.6(A) and 6(B), in which the operation principle of the deceleration device in this embodiment is illustrated. For rapid retrieval of
measuring tape 4, reference should be made to FIG. 6(A) in which theflat pusher plate 74 is pushed back a prescribed distance so as to disengage the speedreduction gear wheel 71 from thetransmission gear wheel 21 thereby releasing thereel 2 from retaring force of thedeceleration unit 7. On the other hand, for Retrieval of measuringtape 4 with a reduced speed, reference should be made to FIG. 6(B) in which theflat pusher plate 74 is pushed forward a prescribed distance so as to engage thehook 73 of thedeceleration unit 7 with thepost 623 on the outer surface of theupper housing 62 and mesh the speedreduction gear wheel 71 of thedeceleration unit 7 with thetransmission gear wheel 21 of thereel 2 thereby putting the rotation ofreel 2 under control of the retarding force of thedeceleration unit 7. - It emerges from the description of the above embodiments that the invention has following noteworthy advantages, namely:
- (1) The deceleration device of the present invention is able to prevent the danger of scratching the user's finger by the tape retrieving in high speed.
- (2) The deceleration device of the present invention is able to prevent damage to the tape tip caused by impringement of the high speed retrieving tape into the housing or abrasion of the tape itself and prolong the lifetime of the tape rule.
