Description

  The present invention relates to a tape measure, and more particularly to a tape measure capable of winding a measuring tape around a case member.

  Conventionally, the tape measure accommodates the measuring tape in the case member by winding the measuring tape along the inner wall of the case member. For example, Japanese Utility Model Laid-Open No. 4-1403 (Patent Document 1) discloses a ring-shaped tape measure in which a measurement tape is wound and accommodated in a ring-shaped accommodation portion.

  Further, for example, German Utility Model No. 202007011752 (Patent Document 2) discloses a tape measure in which a part of a measuring tape is accommodated in a case member in a state where the measuring tape is wound.

Japanese Utility Model Publication 4-1403 German utility model No. 202007011752 specification

  In the tape measure described in the above Japanese Utility Model Publication No. Hei 4-1403, when the measuring tape is wound and housed in the ring-shaped housing portion, the measuring tape inserted from the drawer push-in port contacts the inner wall of the ring-shaped housing portion. Therefore, the frictional resistance is large. Moreover, since the ring-shaped accommodation part is formed in the rectangle, when measuring tape is wound, the measuring tape must be bent at a substantially right angle. Therefore, there is a problem that it is difficult to insert the measurement tape into the ring-shaped accommodation portion.

  Further, in the above-mentioned German utility model No. 202007011752, there is a problem that when the measuring tape is pulled out from the case member, the measuring tape is difficult to stop at the case member because the friction force between the measuring tape and the case member is insufficient. .

  The present invention has been made in view of the above problems, and its purpose is to allow the measurement tape to be easily inserted into the case member and to stop the measurement tape drawn out from the case member at a position where it is desired to be stopped. It is to provide a tape measure that can be used.

  The tape measure of the present invention can be deformed from a linear state to a wound state, and the measuring tape is intended to be restored from the wound state to the linear state, and the measuring tape is moved in and out from the upper surface through the loading / unloading portion. A case member having a cylindrical shape capable of receiving the measurement tape therein and a sleeve having a cylindrical shape that is rotatably accommodated in the case member and capable of winding the measurement tape therein. The case member includes a contact part that defines a part of the entrance / exit part and that contacts the outside of the measurement tape when the measurement tape is taken in and out. The case member is configured to be able to hold the measurement tape in a state where the outside of the measurement tape is in contact with the contact portion.

  In the tape measure of the present invention, the sleeve can wind the measuring tape inside, and the sleeve rotates when the measuring tape is wound. Therefore, the measurement tape can be easily inserted into the case member.

  The case tape can be inserted and removed from the upper surface through the loading / unloading part, and the measuring tape can be held in a state where the outside of the measuring tape is in contact with the contact part. Is spread in the outer diameter direction of the case member, so that the outer side of the measurement tape is held in contact with the contact portion. Therefore, since the measuring tape pulled out from the case member can be stopped at an arbitrary position, the measuring tape can be stopped at a desired position.

  In the tape measure of the present invention, preferably, the case member defines a part of the entrance / exit portion and extends obliquely from the upper surface side to the lower surface side from the radially outer side to the radial center of the case member. It has an upper surface side portion. Accordingly, since the measurement tape can be inserted obliquely into the entrance / exit portion, the measurement tape can be easily placed inside the sleeve when the measurement tape is inserted into the case member from the entrance / exit portion. Further, since the upper surface portion extends obliquely from the upper surface side to the lower surface side from the radially outer side of the case member toward the radial center, when the measuring tape is pulled out from the entrance / exit portion, the outer side of the measuring tape Since the edges of the measuring tape are pushed up toward the contact portion, the outside of the measuring tape and the contact portion can be easily brought into contact with each other.

  In the tape measure of the present invention, preferably, the sleeve includes a notch for making the sleeve deformable in the radial direction. For this reason, when the measurement tape is wound inside the sleeve and the measurement tape in the wound state spreads in the outer diameter direction of the sleeve, the sleeve can be deformed so as to spread in the outer diameter direction. Thereby, rotation of the sleeve can be suppressed by urging the case member with the sleeve. Therefore, it is possible to more effectively stop the measurement tape drawn from the case member at a position where it is desired to stop.

  The tape measure of the present invention preferably further includes a protruding portion protruding from the upper surface. The protrusion is configured to be able to hold the inside of the measurement tape. By holding the inner side of the measurement tape with the protruding portion protruding from the upper surface, it is possible to further strongly suppress the measurement tape in the wound state from spreading in the outer diameter direction of the case member. Therefore, the measuring tape can be further strongly stopped by the protruding portion.

  In the tape measure of the present invention, the material of the measuring tape preferably contains a metal. The measuring tape is curved in the lateral direction. Thereby, the spring property of a measuring tape can be improved with the material and shape of a measuring tape.

  As described above, according to the tape measure of the present invention, the measurement tape can be easily inserted into the case member, and can be stopped at a position where the measurement tape drawn from the case member is to be stopped.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Elements having the same function are denoted by the same reference numerals, and the description thereof will not be repeated unless particularly necessary.

  1 and 2, the tape measure 10 of the present embodiment is configured such that the measuring tape 1 can enter and exit from the upper surface 2a through the entrance / exit part 4a of the case member 2 in the direction of arrow A in FIG. . The measuring tape 1 is accommodated in the case member 2 so that it can be pulled out from the case member 2 in a twisted state. A claw 1a is fixed to the tip of the measuring tape. In addition, the nail | claw part 1a should just be provided as needed on use, and may not be provided if not required.

  The configuration of the tape measure 10 will be described in more detail with reference to FIGS. The tape measure 10 mainly has a measuring tape 1, a case member 2, and a sleeve 3. In FIG. 3, a part of the measuring tape 1 is not shown for easy viewing.

  The measuring tape 1 can be deformed from a linear state to a wound state, and is configured to restore the linear state in the wound state. The measuring tape 1 has a spring property so as to function as a spring. The material of the measuring tape 1 may contain a metal. For example, a carbon steel material, a stainless steel material, or the like can be applied as the material of the measuring tape. With reference to FIG. 5, the measuring tape 1 may be curved in the short direction SD so as to have a spring property.

  Referring to FIGS. 3 and 4 again, the case member 2 is configured to accommodate the measuring tape 1 and the sleeve 3. The case member 2 is configured such that the measuring tape 1 can be put in and out from the upper surface 2 a through the loading and unloading portion 4. The case member 2 is configured to receive the measuring tape 1 therein. The case member 2 has a cylindrical shape.

  Referring to FIGS. 1 and 2 again, the case member 2 has a contact portion 20 that defines a part of the entrance / exit portion 4a. The contact portion 20 is provided so that the outer side 1c of the measurement tape 1 contacts when the measurement tape 1 is taken in and out. The case member 2 is configured to be able to hold the measurement tape 1 in a state where the outer side 1c of the measurement tape 1 is in contact with the contact portion 20.

  An opening 6 is provided on the upper surface 2 a of the case member 2. Since the opening 6 is provided, the leading end of the measuring tape 1 is easily accommodated in the case member 2 and taken out. The opening 6 may be provided in a sector shape at an angle of 120 ° to 140 °, for example, when viewed from the upper surface 2a. The fan-shaped radial portion of the opening 6 is formed obliquely with respect to the radial direction of the case member 2 so as to have an angle larger than a right angle with respect to the radial center of the case member 2. Thereby, when the measurement tape 1 is inserted into the case member 2 from the entrance / exit 4 through the opening 6, the measurement tape can be easily inserted into the entrance / exit 4.

  In the case member 2 according to the embodiment of the present invention, an opening is formed on the lower surface opposite to the upper surface 2a. At both ends of the opening 6, an entrance / exit 4 is provided for the measurement tape 1 to enter and exit the case member 2.

  The entrance / exit part 4a is provided in the left end part of the opening part 6 in FIG. 1, and the entrance / exit part 4b is provided in the right end part. For this reason, the user can select whether the measuring tape 1 is put in and out from either of the loading / unloading portions 4a and 4b. The user can comfortably use the tape measure of this embodiment regardless of whether he is right-handed or left-handed.

  Further, on the upper surface 2a of the case member 2, the portion other than the opening 6 has a mortar shape whose area decreases from the upper surface 2a toward the lower surface side. The opening 6 is formed obliquely by a mortar shape. That is, the opening 6 is formed obliquely in the center direction of the case member 2 from the upper surface 2a side to the lower surface side. For this reason, the case member 2 defines a part of the entrance / exit part 4, and the upper surface side that extends obliquely from the upper surface 2a side to the lower surface side from the radially outer side of the case member 2 toward the radial center. It has a portion 2c.

  Thereby, the measuring tape 1 can be inserted into the entrance / exit 4 at an angle. Therefore, when the measuring tape 1 is inserted into the case member 2 from the entrance / exit 4 through the opening 6, the measuring tape 1 can be easily placed inside the sleeve 3. Further, since the upper surface side portion 2c extends obliquely from the outer surface in the radial direction toward the center in the radial direction from the upper surface 2a toward the lower surface, the measuring tape 1 is pulled out from the entrance / exit 4 Moreover, since the edge of the outer side 1c of the measuring tape 1 is pushed up toward the contact part 20, the outer side 1c of the measuring tape 1 and the contact part 20 can be easily brought into contact with each other. Moreover, since a user can insert a finger | toe easily in the opening part 6 by mortar shape, operativity improves.

  A protrusion 5 is provided on the upper surface 2 a of the case member 2. The protruding portion 5 is provided so as to protrude from the upper surface 2a. The protruding portion 5 is configured to be able to hold the inner side 1 b of the measuring tape 1. The protrusion 5 is provided along the opening 6.

  Referring to FIGS. 3 and 4 again, case member 2 may be made of resin, for example. The case member 2 has an upper case member 21 and a lower case member 22. The upper case member 21 is engaged with the upper engagement portion 21a of the upper case member 21, the lower engagement portion 22a of the lower case member 22, the outer peripheral end portion of the upper case member 21, and the outer peripheral end portion of the lower case member. The lower case member 22 is configured to be engageable. The upper case member 21 and the lower case member 22 are screwed with screws 7 in an engaged state.

  The sleeve 3 is rotatably accommodated in the case member 2. The sleeve 3 is configured so that the measuring tape 1 can be wound around the inner peripheral surface 3 c inside the sleeve 3. The measuring tape 1 is not fixed to the sleeve 3. The measuring tape 1 is wound so as to be laminated on the inner diameter side of the sleeve 3 along the inner peripheral surface 3 c of the sleeve 3. The sleeve 3 has a cylindrical shape. The sleeve 3 may be made of resin, for example.

  The sleeve 3 is configured so that the outer peripheral surface 3 a can slide on the inner peripheral surface 2 b of the case member 2 in a state where the measuring tape 1 is received. The sleeve 3 may have a protrusion on the outer peripheral surface 3a. In this case, the protruding portion particularly slides on the inner peripheral surface 2 b of the case member 2. The sleeve 3 is configured to be able to bias the case member 2 by spreading in the outer diameter direction when the measuring tape 1 spreads in the outer diameter direction of the sleeve 3.

  The sleeve 3 has a notch 3b for making the sleeve 3 deformable in the radial direction. The notch 3 b is formed on the side surface of the sleeve 3. The cantilever 3d formed in a cantilever state by the notch 3b is easily elastically deformed in the radial direction. Therefore, the sleeve 3 is configured such that the measurement tape 1 in the wound state spreads in the outer diameter direction of the sleeve 3 so that the cantilever portion 3d is elastically deformed in the outer diameter direction and biases the case member 2. Yes.

Next, the usage state of the tape measure of one embodiment of the present invention will be described.
First, referring to FIG. 1 again, a state where the measuring tape 1 is held by the case member 2 will be described. Since the measuring tape 1 is pulled out from the upper surface 2 a of the case member 2, the measuring tape 1 is twisted and pulled out in a direction along the upper surface 2 a of the case member 2 from the entrance / exit portion 4 a of the case member 2. The outer side 1c of the measuring tape 1 is held in contact with a contact portion 20 that defines a part of the entrance / exit portion 4a. The contact portion 20 is located at a boundary portion between the entrance / exit portion 4 a and the opening 6. The inner side 1b of the measuring tape 1 is held in contact with the protrusion 5. Thus, the measuring tape 1 is in contact with the case member 2 on both the inner side 1b and the outer side 1c of the measuring tape.

  In this state, the measuring tape 1 is spread in the outer diameter direction of the sleeve 3 by a restoring force (elastic force) that attempts to restore the wound state to a linear state. For this reason, both the inner side 1 b and the outer side 1 c of the measuring tape 1 are pressed against the case member 2. The measuring tape 1 is locked to the case member 2 by the frictional resistance at the contact portion between the measuring tape 1 and the case member 2.

  Further, the outer peripheral surface 3 a of the sleeve 3 is pressed against the inner peripheral surface 2 b of the case member 2 by an elastic force that tries to restore the state in which the measuring tape 1 is wound up to a linear state. The rotation of the sleeve 3 is restricted by the frictional resistance of the contact portion between the inner peripheral surface 2 b of the case member 2 and the outer peripheral surface 3 a of the sleeve 3.

  Next, with reference to FIG. 6, a state in which the measuring tape 1 enters and exits from the case member 2 will be described. When a force is applied to the inner diameter side of the case member 2 with respect to the measurement tape 1 so as to release the holding of the measurement tape 1 from the state shown in FIG. 1, the frictional force between the measurement tape 1 and the case member 2 becomes weaker. As a result, the measuring tape 1 can enter and leave the case member 2. More specifically, the frictional force between the outer side 1c of the measuring tape 1 and the contact part 20 is weakened, and the frictional force between the inner side 1b of the measuring tape 1 and the protruding part 5 is weakened. As a result, the holding of the measuring tape 1 is released and the measuring tape 1 can enter and exit the case member 2.

  Note that the measurement tape 1 and the case member 2 do not have to be completely in non-contact, and the holding may be released so that the measurement tape 1 can be moved in and out of the case member 2. Therefore, the measuring tape 1 may be put in and out while sliding on the case member 2.

  When the measuring tape 1 is moved in and out of the case member, the outer peripheral surface 3 a of the sleeve 3 slides on the inner peripheral surface 2 b of the case member 2 in a state where the measuring tape 1 is received by the sleeve 3. At this time, since the sleeve 3 rotates, the measuring tape 1 is easily inserted into the case member 2 and pulled out.

  When a force is applied to the inner diameter side of the case member 2 with respect to the measuring tape 1, the measuring tape 1 is pulled out from the case member 2 by the elastic force of the measuring tape 1 to be restored from the state of being caught. Receive power. Therefore, the measuring tape 1 can be pulled out from the case member 2 using the elastic force of the measuring tape 1.

Next, the function and effect of the embodiment of the present invention will be described.
In the tape measure 10 of one embodiment of the present invention, the sleeve 3 can wind the measuring tape 1 inside, and the sleeve 3 rotates when the measuring tape 1 is wound. Therefore, the measuring tape 1 can be easily inserted into the case member 2.

  The case member 2 is configured such that the measuring tape 1 can be put in and out of the upper surface 2a through the loading and unloading portion 4, and the measuring tape 1 can be held in a state where the outer side 1c of the measuring tape 1 is in contact with the contact portion 20. When the measuring tape 1 in the wound state spreads in the outer diameter direction of the case member, the outer side 1c of the measuring tape 1 is held in contact with the contact portion 20. Therefore, since the measuring tape 1 drawn out from the case member 2 can be stopped at an arbitrary position, the measuring tape 1 can be stopped at a desired position.

  In the tape measure 10 of one embodiment of the present invention, since the measurement tape 1 is locked by the case member 2 in the direction in which the measurement tape 1 spreads from the wound state, the tape measure 10 is rotated in all directions up, down, left and right. Even in this case, the measuring tape 1 drawn out from the case member 2 can be stopped at a position where it is desired to stop.

  Moreover, in the tape measure 10 of one embodiment of the present invention, the case member 2 defines a part of the entrance / exit part 4, and the lower surface from the upper surface 2a side toward the radial center of the case member 2 from the radially outer side. It has the upper surface side part 2c extended diagonally toward the side. Thereby, since the measuring tape 1 can be inserted into the entrance / exit part 4 at an angle, the measuring tape 1 is placed inside the sleeve 3 when the measuring tape 1 is inserted into the case member 2 from the entry / exit part 4. It can be made easier. Further, since the upper surface portion 2c extends obliquely from the outer side in the radial direction toward the center in the radial direction of the case member 2 from the upper surface 2a side to the lower surface side, when the measuring tape 1 is pulled out from the loading / unloading portion 4. Since the edge of the outer side 1c of the measuring tape 1 is pushed up toward the abutting part 20, the outer side 1c of the measuring tape 1 and the abutting part 20 can be easily brought into contact with each other.

  Moreover, in the tape measure 10 of one embodiment of the present invention, the sleeve 3 includes a cutout portion 3b for enabling deformation in the radial direction. For this reason, when the measuring tape 1 is wound inside the sleeve 3 and the measuring tape 1 in the wound state spreads in the outer diameter direction of the sleeve 3, the sleeve 3 is deformed to expand in the outer diameter direction. be able to. Thereby, rotation of the sleeve 3 can be suppressed by urging the case member 2 with the sleeve 3. Therefore, the measuring tape 1 drawn out from the case member 2 can be stopped more effectively at a position where it is desired to stop.

  Moreover, in the tape measure 10 of one embodiment of the present invention, the measurement tape 1 in the wound state is held in the case by holding the inner side 1b of the measurement tape 1 by the protruding portion 5 protruding from the upper surface 2a of the case member 2. Spreading in the outer diameter direction of the member 2 can be further suppressed. Therefore, the measuring tape 1 can be further strongly stopped by the protrusion 5.

  Moreover, in the tape measure 10 of one embodiment of the present invention, since the material of the measuring tape 1 includes a metal and the measuring tape 1 is curved in the short direction SD, the measuring tape 1 depends on the material and shape of the measuring tape 1. The spring property can be improved.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The present invention can be applied particularly advantageously to a tape measure capable of winding a measuring tape around a case member.
