Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape measure capable of winding and accommodating a tape in a case, and more particularly, a shock absorbing member for mitigating collision energy of a tape tip locking piece provided at a tape entrance / exit of the case. It is about.

[0002]

2. Description of the Related Art Today, many tape measures are widely used in which the tape for measurement is automatically wound, which is obtained by winding the tape around the winding drum. It is composed of a rotary drum in which a coil spring serving as a biasing means for winding the tape is installed, and a case for accommodating the rotary drum. Usually, the tape is stored in the case, so when measuring, pull the locking piece provided at the tape tip that locks the tape inlet / outlet of the case with your finger, and then pull the tape pulled out properly. The desired measurement is performed by pulling out.

When the tape is housed in the case after the measurement is completed, the tape braking device or the tape stopped by the hand is released so that the tape is installed in the rotating drum in the case. The coil spring automatically winds the tape into the case, and the locking piece at the tip of the tape is locked to the tape inlet / outlet to complete the winding of the tape. Then, a shock absorbing member is provided at the tape entrance / exit to alleviate (including also absorb) the collision energy of the locking piece that collides with the tape entrance / exit at a considerable speed.

However, since the shock absorbing member is constructed for the purpose of relaxing the collision energy of the locking piece, it is only possible to perform a buffering operation in the depth direction of the case, and the shock absorbing member can be operated from a direction other than the collision of the locking piece. The shock cannot be mitigated. For this reason, when the locking piece is locked at the tape inlet / outlet, when the locking piece is impacted from below by dropping the tape measure or hitting another member, that is, When the stop piece receives an impact on the bottom, the locking piece is pushed upward in the case and hits the shock absorbing member,
The shock absorbing member and the locking piece were often damaged.

[0005]

An object of the present invention is to solve the above-mentioned problems, and to reduce the collision energy of the locking piece due to the winding of the tape and the case of the case in which the locking piece is locked at the tape entrance / exit. It is an object of the present invention to provide a shock-absorbing member for a tape measure, which is capable of reducing the impact when the impact is applied to the locking piece from the lower side by dropping or the like.

[0006]

SUMMARY OF THE INVENTION The gist of the present invention is that in a tape measure having a biasing means for biasing the tape in the winding direction, the collision energy of the tape tip locking piece is applied to the tape entrance and exit of the case. A shock absorbing member for relaxing is provided, and the shock absorbing member is a plate body having an appropriate thickness and having a tape through hole in a lower portion thereof, and the plate body is fitted at a predetermined portion with a guide means formed in the case. A shock-absorbing member for a tape measure, characterized in that the tape is slidable in an upward direction and is deformable in a winding direction of the tape around a predetermined fitting portion as a fulcrum.

The shock absorbing member of the tape measure according to the present invention will be described in detail. The case is a member for accommodating the tape for measurement and is also the main body of the tape measure. The case is made of a material such as a resin or a metal that is appropriately formed into a desired shape, and a shaft is erected on the inner wall of the case, and a measuring tape having a memory printed on the shaft is used. A rotating drum wound around the shaft is pivotally supported. A coil-shaped winding spring for winding the tape is provided inside the rotary drum, and the tape is biased in the winding direction.

The tape enters and exits through a tape inlet / outlet provided at the lower part of the front wall of the case, and when the winding of the tape is completed, a locking piece at the tip of the tape is locked in the tape inlet / outlet. This prevents the tape from being drawn into the case. Since the locking piece collides with the tape entrance / exit at a considerable speed, the tape entrance / exit is provided with an impact buffering member that alleviates the collision energy of the locking piece (including the absorbing action).

The shock absorbing member is a plate body having an appropriate thickness and having a tape through hole in a lower portion thereof, and the plate body is fitted on a guide means formed at a predetermined portion of the case, so that the tape cushion is mounted on the tape. It is provided so as to be slidable in the direction and capable of being bent and deformed in the winding direction of the tape with a predetermined fitting portion as a fulcrum. The material of the plate is not particularly limited, and any suitable material may be used, but it is desirable to use a suitable resin material having excellent moldability. Further, the plate body may have a form in which a cut is provided following the tape through hole, and may be selected in consideration of ease of assembling and forming the tape measure.

The thickness of the plate is not particularly limited, but a suitable thickness may be appropriately selected in consideration of the strength of tape collision energy depending on the type of tape measure used and the size of the locking piece. Further, the entire plate body may have the same thickness, but the thickness may be changed depending on the portion so that the collision energy can be more flexibly relaxed. Specifically, the part that receives the impact force (the part such as the collision part with the locking piece and the fitting part with the guide formed on the case) is thick and the part that absorbs the impact force (the plate is usually In the position (2), the thickness between the collision portion with the locking piece and the fitting portion with the guide formed on the case) may be reduced.
The change in thickness may be changed stepwise or tapered.

The size and shape of the tape through hole formed in the lower portion of the plate is not particularly limited, and may be any shape, but it is preferably a crescent shape close to the cross-sectional shape of the tape. Is good. In addition, the length of the tape through hole in the vertical direction may be extended so that the tape can move upward in the tape through hole. It should be shorter than the vertical length of the stop.

Further, the length of the tape through hole may be set longer than the length of the tape tip locking piece in the vertical direction. In that case, an eave of an appropriate length is pulled in behind the plate. The tape should be formed so as to prevent the tape from being drawn into the case. The eaves may be provided in parallel with the bottom wall of the case, or may be provided obliquely so as to gradually approach the tape as it goes deeper into the case. The width of the eaves (in the short side direction of the tape) is not particularly limited, and may be about the same as the width of the tape. The plate may be a flat plate having an appropriate thickness, or may be curved with an appropriate curvature in the tape drawing direction or the tape drawing direction.

When the plate member is fitted to the guide means, the plate member must be fitted on (inside) the guide means so as to be slidable (freely movable) in the upward direction of the tape.
Further, it is desirable that at least the downward drop is prevented, and in that case, the guide means, the plate body or the case is used alone or in combination, and further, the tape including the tape is provided in the downward direction. It is only necessary to prevent the fall. And
The plate body may be slidably fitted to the guide means, but it may be a suitable biasing means, for example, an elastic member such as a leaf spring or a coil spring which is a separate member, or an elastic structure provided on the plate body. It may be fitted in a downwardly biased state.

The fitting portion of the plate body is not particularly limited as long as the suitable portion is fitted to the guide means and the plate body can slide upward in the tape inlet / outlet. The fitting part may be appropriately selected depending on the structure of the guide means provided in the case and the installation form. Further, a large number of small protrusions may be formed at the fitting portion to reduce frictional resistance during sliding. Then, as a preferred specific relationship between the plate body and the guide means, the plate body has its fitting portions at both ends in the tape width direction, and the guide means includes both inner side walls of the case in the tape width direction. The opening portions of the rails having a substantially U-shaped cross section are made to face each other and extend upward in the tape inlet / outlet, and both side ends of the plate body are fitted into the opening portions (groove portions) of the rails.

In addition, the plate body is formed with fitting portions of appropriate shape projecting from both ends in the short side direction of the tape, and the guide means has a substantially U-shaped cross section on both inner side walls of the case in the short side direction of the tape. The rail openings are made to face each other and extend upward in the tape inlet / outlet, and the fitting portion formed by projecting the plate body is fitted into the rail opening (groove). The positions of the fitting portions formed on both side ends of the plate body may be any of the upper portion, the central portion and the lower portion as long as they do not interfere with the shock absorbing operation of the plate body, but it is desirable that the engaging pieces are provided on the upper portion. It is preferable to form it in such a size that it can withstand the collision energy. Also, only one fitting portion may be provided on each side, but a plurality of fitting portions may be formed.

Further, in the guide means, a large number of projections are continuously formed in two rows in the upper direction of the tape inlet / outlet at appropriate intervals on both inner side walls of the case in the tape short side direction, so that both side ends of the plate body or You may fit the protrusion-formed fitting part between the protrusions connected in two rows. The shape of the protrusion is not particularly limited, but it must be selected in consideration of the shock absorbing action of the plate body. When the plate body is curved with an appropriate curvature as described above, the rail or the protrusion must be formed according to the curvature.

The fact that the plate body can be flexibly deformed in the winding direction of the tape around a predetermined fitting portion as a fulcrum means that the plate body is fitted to the guide means and is placed on the tape as described above. It is possible to slide in the direction,
On the other hand, the fitting prevents the tape from moving in the advancing / retracting direction, and when the locking piece at the tip of the tape collides, the predetermined part of the plate body moves in the tape winding direction around the fitting part as an axis. It is supposed to bend. That is,
It is a flexible deformation.

The fitting form and method are not particularly limited as long as the tape can be fitted so as to prevent the tape from moving in the forward and backward directions. As a specific example, the fitting portion may be formed in a quadrangle or another polygon, and the guide means may be formed in accordance with the shape. Further, it is sufficient that the movement of the tape of the plate body in the advancing / retracting direction can be prevented without particularly fitting the fitting portions. When the plate body performs the shock absorbing operation, the position of the fitting portion of the plate body on (inside) the guide means is particularly limited as long as the plate body can perform the shock absorbing operation without any trouble. However, the lower end of the guide means or its vicinity is preferable.

[0019]

Since the shock absorbing member of the tape measure of the present invention is constructed as described above, if the tape through hole in the plate has a crescent shape close to the cross sectional shape of the tape, the locking piece at the time of winding the tape In the relaxation of the collision energy of the tape, when the tape is wound and the tape tip locking piece collides with the shock absorbing member provided at the tape entrance / exit, the collision causes the plate body to use the fitting portion with the guide means as a fulcrum. The lower part following the fitting part tries to rotate in the tape winding direction. That is, the plate body is flexibly deformed in the winding direction of the tape, whereby the rotation of the plate body is suppressed and the collision energy is absorbed.

When a shock is applied to the locking piece from below by dropping the case or hitting another member, the locking piece is pushed upward together with the tape by the shock, and , Push the plate together with the tape upward. This plate body is guided by the guide means and slides upward. That is, the locking piece and the tape can escape upward by sliding the plate. As a result, the shock received by the locking piece is absorbed.

If the tape through hole provided in the plate is wide in the longitudinal direction, the tape is wound and the tape tip locking piece is the tape in order to reduce the collision energy of the locking piece when winding the tape. When it collides with the shock absorbing member provided at the entrance / exit, the collision causes the plate body to rotate in the tape winding direction around the fitting portion with the guide means as a fulcrum and the lower portion following the fitting portion. That is, the plate body is flexibly deformed in the winding direction of the tape, whereby the rotation of the plate body is suppressed and the collision energy is absorbed.

When a shock is applied to the locking piece from below due to the case falling or hitting another member, the locking piece is pushed upward together with the tape by the shock and the plate is pushed up. Move upward in the tape passage of the body.
When the impact is weak, the impact received by the locking piece is absorbed while moving upward in the tape passage hole. That is, the impact is absorbed by the locking piece escaping upward in the tape through hole. When the impact is strong, the tape is moved upward in the tape through hole to hit the upper end of the tape through hole, that is, the plate body, and the plate body is also pushed upward together with the tape. The plate body is guided by the guide means and slides upward. That is, the locking piece and the tape can further escape upward by sliding the plate.
As a result, the shock received by the locking piece is absorbed.

[Effect] Since the shock-absorbing member of the tape measure of the present invention is configured as described above, when the locking piece is locked at the tape entrance / exit, the locking piece is pushed from below by a fall of the case or the like. When an impact is applied, that is, when the locking piece is impacted by the bottom portion, the impact can be efficiently mitigated by the action of the plate body which is the impact buffering member. Further, the impact energy of the locking piece due to the winding of the tape is also effectively mitigated by the action of the plate member which is the buffer member.

Further, since the shock absorbing member, that is, the plate body is made of a one-piece part and has an extremely simple shape, the manufacturing cost of the mold for molding the shock absorbing member can be kept low, and therefore the tape measure can be obtained. The manufacturing unit price of can be reduced. In addition, since the structure is extremely simple, the assembly work is easy. Further, even if the tape measure is not newly equipped with the shock absorbing member, or if it is intended to equip the tape measure in which only the collision energy of the locking piece is alleviated, it can be easily equipped.
