Description

  The present invention relates to a rod-shaped portion holder for detachably gripping an outer peripheral portion of a portion of a rod-shaped portion in an axial direction of an object having a rod-shaped portion such as a mop handle and holding the mop or the like in a suspended state. About.

  In WO2005 / 042212 (Patent Document 1), a grip body comprising a pair of holding portions integrally formed of a rubber-like material and a connecting portion connecting both holding portions is used in a part of an axial direction of a mop handle or the like. There is described a rod-shaped holder that can detachably hold an outer peripheral portion and hold a mop or the like in a suspended state.

  This rod-shaped portion holder is supported so that both holding portions can reciprocate around a predetermined rotation axis, does not hold an object and does not receive external force, and both holding portions which are front surfaces of both holding portions. When the entire surface is located in front of both rotation axes, and the rod-shaped portion of the object is in a state where the axial direction of the rod-shaped portion is parallel to the rotation axis, the connecting portion is behind the rotation axis. When the pair of holding portions are turned inwardly to each other, the outer peripheral portion of the rod-shaped portion is held in the holding state in which the holding portion and the connecting portion, that is, the holding portion are pressed and held by the holding portion. Elasticity can be changed by elastically deforming.

However, this type of conventional rod-shaped portion retainer does not necessarily have a sufficient holding force when the outer periphery of an axial portion of a mop handle or the like is detachably gripped and the mop is held in a suspended state. Instead, it tended to slip off over time.
WO2005 / 042212

  The present invention has been made in view of the above problems, and the object of the present invention is to hold the rod-shaped part of the object by the holding surfaces of both holding parts more reliably in the holding state, and the holding state is May provide a stable rod retainer.

(1) The rod-shaped part holder of the present invention that achieves the above object is
A holding body having a pair of holding portions and a connecting portion for holding an object having a rod-like portion, and a support mechanism for supporting each holding portion so as to be capable of reciprocating rotation around a predetermined rotation axis. With
The pair of holding portions can reciprocate around a pair of parallel rotation axes, can be elastically deformed, and can be radially outwardly spaced from the rotation axis. Has a holding surface that is parallel to the turning axis,
The connecting portion has a belt-like shape that can be elastically deformed, and in a state where the both holding surfaces are located on the front side that is one side of a virtual plane including both rotation axes, Connecting the positions separated from the rotation axis in the radial direction among the parts to be
The gripping body does not hold the object and does not receive external force, and the both holding surfaces are positioned in front of both rotation axes, and the rod-shaped part of the object causes the rod-shaped part to move in the axial direction. In which the connecting portion is pushed rearward of the rotation axis and the pair of holding portions rotate inwardly with each other in a state parallel to the rotation axis. Can be changed by the elastic deformation of both the holding part and the connecting part, the holding state that is pressed and held by both holding parts and the connecting part of the gripping body,
Between the release state and the holding state of the gripping body, the force acting on the rod-like portion due to the elastic deformation of both the holding portion and the connecting portion prevents the rod-like portion from being pushed backward and pushes it back forward. A rod-shaped part retainer that is configured to switch between a section that acts on and a section that acts to prevent the rod-shaped part from returning to the front,
The both holding portions are characterized in that at least the width of the holding surfaces in the rotational axis direction is larger than the width of the connecting portions in the rotational axis direction.

  When the gripping body of the rod-shaped holder is in a released state, that is, the gripping body does not hold the rod-shaped part of the object and is not subjected to external force, and the entire holding surface of both the holding parts is In the case where the object is located in front of the virtual plane including the movement axis, the rod-shaped part of the object can be held by the holding part and the connecting part, that is, the gripping body as follows.

  With the rod-shaped part of the object, the holding part is connected between the holding parts and positioned between the two holding parts in the state where the axial direction of the bar-shaped part is parallel to the rotation axis of the holding parts. It pushes back from the rotation axis. As a result, both holding portions supported by the support mechanism are elastically deformed and rotated around the respective rotation axes so as to be close to each other toward the rear, and the connecting portions are convexly curved toward the rear. Thus, a portion of the outer peripheral portion of the rod-like portion that exceeds half a circumference is in a holding state in which the holding portion and the connecting portion that connects the two are pressed and held. However, it is difficult to grip the rod-shaped portion when the outer shape such as the outer diameter of the rod-shaped portion is too large or too small compared to the distance between the two holding portions in the gripping body.

  In order to release the rod-shaped portion of the object from the holding body of the rod-shaped portion holder, that is, the holding by the both holding portions and the connecting portion, the rod-shaped portion is pulled forward. As a result, both holding parts supported by the support mechanism are rotated in the opposite direction to the case where the rod-like parts are held around the respective rotation axes so as to be elastically deformed and separated from each other toward the front. The connecting part that has been elastically stretched and deformed in a convex curved state toward the rear moves toward the front and elastically recovers, does not hold the object and does not receive external force, and holds both holding parts The entire surface is in a released state positioned forward of the rotation axis of both holding portions.

  In this way, both the holding part and the connecting part supported by the support mechanism so as to be able to reciprocate around the rotation axis are elastically deformed, so that the release state and the holding state can be changed, and the holding body is released. Between the transition between the state and the holding state, the force acting on the rod-like portion due to elastic deformation of both the holding portion and the connecting portion acts to prevent the rod-like portion from being pushed backward and to push it forward. The section that acts to prevent the rod-shaped portion from returning to the front, that is, the connecting portion that has been elastically stretched and deformed in a convex curved state toward the rear is contracted to try to push the rod-shaped portion back forward. However, the section in which both holding parts exceed the force to prevent the rod-shaped part from moving forward is switched. In the holding state in which the gripping body grips the rod-shaped portion of the object, the rod-shaped portion acts so as to prevent the rod-shaped portion from returning to the front, so that it becomes stable.

  The both holding portions have at least the width in the rotation axis direction of their holding surfaces larger than the width in the rotation axis direction of the connecting portion. Therefore, the part of the outer periphery of the rod-shaped part that exceeds half the circumference is connected to both holding parts supported by the support mechanism, and the connection part elastically stretched and deformed into a convex curved state toward the rear by connecting both of them. Compared to the case where the holding portion of both holding portions grips the rod-shaped portion of the object in the holding state held in pressure contact by the holding portion, the rotation axis width of the holding surface is the same as the rotation axis width of the connecting portion. In the holding state in which the connecting portion is elastically stretched and deformed in a convex curved shape toward the rear, since the width of the connecting portion is smaller than the width of the holding surface in the rotating axis direction. Since the elastic restoring force that pushes the part forward to release the holding of the rod-like part does not become too large, the holding state is stabilized.

  (2) The holding surface may have a protruding portion that protrudes in the rotation axis direction from the connecting portion on both sides in the rotation axis direction.

  In this case, in the holding state in which the outer circumference of the rod-shaped portion of the object exceeds half the circumference is pressed and gripped by the both holding portions and the connecting portion, the force that causes the rod-shaped portion to separate from the holding portion and the connecting portion in the axial direction. When the force is applied, the overhanging parts opposite to the direction of the force that separates the holding parts in the rotational axis direction elastically deforms in the direction of tightening the rod-shaped parts together, so that the axial direction separation of the rod-shaped parts is more effective. Can be prevented.

  (3) The holding portion is an elastically deformable holding plate that forms a holding surface at a radially outer end with respect to the rotation axis and a thickness direction that is radial with respect to the rotation axis. The holding plate-like portion can have a larger width in the rotational axis direction than other portions of the holding portion.

  (4) The connecting portion may be thinner than the holding plate-like portion.

  In this case, since the thickness of the connecting portion is smaller than the thickness of the holding plate-like portion, the rod-like portion is pushed back forward in the holding state where the connecting portion is elastically stretched and deformed in a convex curved shape toward the rear. The elastic restoring force for releasing the holding of the part is prevented from becoming too large, and the holding state is stabilized.

  In the rod-shaped part cage of the present invention, the width of at least the holding surface of both holding parts is larger than the width of the connecting part in the rotating axis direction. Gripping of the rod-shaped portion of the holding portion is more reliable than when the rotation axis direction width of the holding surface is the same as the rotation axis direction width of the connecting portion, and the rotation axis direction width of the connecting portion is Since it is smaller than the rotation axis direction width, the elastic restoring force that pushes back the rod-like portion forward to release the holding of the rod-like portion in the holding state where the connecting portion is elastically stretched and deformed in a convex curved state toward the rear. Is not too large, so the holding state is stable.

  Embodiments of the rod-shaped holder of the present invention will be described with reference to the drawings.

  The drawings all relate to a rod-shaped holder as an embodiment of the present invention. FIG. 1 is a perspective view, FIG. 2 is a plan view, FIG. 3 is a front view, FIG. 4 is a side view, and FIG. FIG. 6 is a plan view of a state where the rod-shaped portion is held, FIG. 7 is a front view of the state where the rod-shaped portion is held, and FIG. 8 is a side view of the state where the rod-shaped portion is held.

  This rod-shaped part holder A includes a pair of holding parts H formed integrally with a rubber-like material (a high-molecular substance exhibiting rubber-like elasticity such as a synthetic rubber such as styrene-butadiene rubber or a vulcanized natural rubber) and a connecting part. It comprises a gripping body G composed of a part J, a rotation shaft P fixedly provided on each of the holding portions H, and a support body S that supports both rotation shafts P so as to be capable of reciprocating rotation.

  The object O is a mop and has the rod-like part B as a handle. A target object is a thing provided with a rod-shaped part or a thing equivalent to this. Examples of the object include a mop, a bag, a beard, an umbrella, a cane, and the like. The whole may be a rod-shaped part. Further, the object is not limited to an elongated shape. An instrument having rod-shaped handle portions on both sides can be held by both rod-shaped portion holders.

  The rod-shaped part may be solid or hollow. The cross-sectional shape of the outer periphery of the rod-shaped portion may be various non-circular cross sections other than circular and regular polygon. Examples of the bar-like portion viewed from the function include a handle and a handle, but are not limited thereto.

  The pair of holding portions H are connected by a connecting portion J. Both holding portions H are symmetrical with respect to the connecting portion J. However, as the shapes of both the holding part and the connecting part, those having an asymmetric shape with each other can also be adopted.

  The holding part H has a base part H1 having an insertion hole (not shown) through which a rotation shaft P having a circular cross-section having a large-diameter head at one end is inserted, and a rotation axis x (insertion hole) of the rotation shaft P. A holding plate H2 that is elastically deformable and that is located at the radially outer end with respect to the rotation axis x, and is held against the base H1. It consists of a pair of support plate portions H3 that support the plate-like portion H2 and are opposed to each other with a circumferential interval therebetween in parallel to the rotation axis. The holding plate-like portion H2 forms a holding surface H2a on the outer side in the radial direction. The holding surface H2a is directed radially outward at a position spaced radially from the rotation axis x and is parallel to the rotation axis x. Note that the holding surface H2a may have irregularities, through portions, and the like.

  The holding plate-like portion H2 protrudes on both sides in the rotation axis x direction from the base H1 and the pair of support plate portions H3, and the holding surface H2a has two opposite sides in the rotation axis x direction and is opposed to the other. Two sides form a square shape in a direction perpendicular to the rotation axis x.

  The inner sides of both holding plate-like portions H2 are connected by a connecting portion J. The outer sides of both holding plate portions H2 project outward from the support plate portion H3.

  A through-hole portion T is formed between the base portion H1, the support plate portions H3, and the holding plate-like portion H2 in the holding portion H. This through-hole portion T makes the holding portion H easily and moderately elastically deformable. However, it is possible to have no through-hole part or a concave part that does not penetrate.

  Each holding portion H is inserted into the insertion hole, and a rotation shaft P that is integral with the holding body is supported by the support body S so that the holding surface H2a can be rotated as shown in FIG. It can reciprocate between a state of facing substantially forward and a state in which both holding surfaces H2a face inward of each other. In this example, the holding portion H is provided by a rotation shaft P inserted through the insertion hole in the base portion H1 of the holding portion H and a support S that supports the rotation shaft P so as to be reciprocally rotatable around the rotation axis x. Is supported so as to be reciprocally rotatable around the rotation axis x. As an example of the support mechanism, a rotation shaft integrally formed with the holding portion is rotatably supported, a fixed shaft body is inserted into an insertion hole provided in the holding portion, and the holding portion is attached to the fixed shaft body. The thing etc. which rotate are mentioned.

  The holding part H of this example is entirely deformable elastically, but for example, the base part or a part other than the base part and the base part of the pair of support plate parts can be elastically deformable. .

  The connecting portion J has a belt shape that can be elastically deformed, and the entire holding surface H2a is assumed to be on one side of the virtual plane v including both rotation axes x (that is, a surface including both rotation axes x). In the state (the state shown in FIG. 2) that is located on the front side that is one side of the surface in the case where the two holding portions H are opposed, both holding plate-like portions H2 (radial direction from the rotation axis) Are connected to each other). The surface of the connecting portion J, that is, the surface on the side continuous with the both holding surfaces H2a may have irregularities, penetrating portions, and the like. The connecting portion J may be composed of two or more strips or strings in parallel in the axial direction.

  The support S has a pair of front projecting portions S1 that support both pivot shafts P, and a connecting base portion S2 that connects and supports the base portions of both front projecting portions S1, and both the front projecting portions S1 and the connecting base portion S2. The portion surrounded by the circle forms a space C in which the rod-shaped portion B is located in a state where the rod-shaped portion B is gripped by the grip body G. Each front protrusion S1 is formed of a pair of flat plate portions that are parallel to the rotation axis x direction and rotatably support both end portions of the rotation shaft P, and the base portion H1 of the holding portion H is located between both flat plate portions. To do.

  When the rod-shaped holder A is in the released state shown in FIGS. 1 to 4, that is, the object O is not held by the gripper G and is not subjected to external force, and the entire holding surface H2a of both holding parts H is In the case where the holding part H is located in front of the rotation axis x (virtual plane v) of the holding parts H, the holding part H and the connecting part of the stick-like part holder A are used as follows. J, that is, it can be held by the gripping body G.

  A connecting portion J that is located between the holding portions H and connects the two in a state where the axial direction of the rod-like portion B is parallel to the rotation axis x of the holding portions H by the rod-like portion B of the object O. Is pushed rearward from the rotation axis x (virtual plane v) of both holding portions H. As a result, both holding portions H supported by the support S via both rotation axes P rotate around the respective rotation axes x so as to approach each other toward the rear while being elastically deformed, The connecting portion J is elastically stretched and deformed in a convex curved state toward the rear, and as shown in FIGS. It will be in the holding | maintenance state pressure-gripped by the connection part J which connects the part H and both. In the state where the outer peripheral portion of the rod-shaped portion is pressed and gripped, the gripping body presses and grips, for example, a portion of the outer peripheral portion of the rod-shaped portion that continuously exceeds half a circle, for example, 6/10 to 9/10. Normally, the front part is removed, but it may be all around.

  In order to release the rod-like part B of the object O from being held by the holding parts H and the connecting parts J which are the gripping bodies G of the stick-like part holder A, the rod-like part B is pulled out to the front F. As a result, the holding portions H supported by the support S via the both rotation axes P are elastically deformed, and the rod-like portions B are held around the respective rotation axes x so as to be separated from each other toward the front. The connecting portion J, which has been rotated in the opposite direction to that when it is made to move and elastically deformed in a convex curved state toward the rear, moves toward the front and is elastically restored to restore the object O. The entire holding surface H2a of both holding portions H is in a released state positioned forward of the rotation axis x (virtual plane v) of both holding portions H without being held and receiving external force (FIGS. 1 to 4). ).

  As described above, the two holding portions H and the connecting portion J supported by the support S so as to be reciprocally rotatable around the rotation axis x through the both rotation shafts P are elastically deformed, thereby releasing the state. The force acting on the rod-like portion B due to the elastic deformation of both the holding portions H and the connecting portion J between the release state of the holding body G and the change of the holding state can be changed by the rod-like portion B. A section that acts to prevent it from being pushed backward and push it back forward, and a section that acts to prevent the rod-like part B from returning forward, that is, elastically stretched into a convex curved state toward the rear The connecting portion J that has been contracted tries to push the rod-shaped portion B back forward, but the section where the holding force H prevents the rod-shaped portion B from moving forward is switched. Therefore, the gripping body G is stable in the holding state in which the rod-like part B of the object O is held. Note that the switching can be changed depending on the size of the rod-like portion B, or the diameter in the case of a circle.

  Both holding portions H have at least the width of the holding surface H2a in the direction of the rotational axis x, and the width of the connecting portion J in the direction of the rotational axis x. Therefore, the part of the outer periphery of the rod-shaped part B that exceeds three quarters is connected to both the holding parts H supported by the support S via both rotating shafts P, and the two are connected to the rear. In the holding state in which the connecting portion J is elastically stretched and deformed into a convex curved state, the rod-like portion B of the object O is held by the holding surfaces H2a of both holding portions H. Compared to the case where the width of the dynamic axis x direction is the same as the width of the connecting portion J in the rotational axis x direction, the width of the connecting portion J in the rotational axis x direction is the same as the direction of the rotational axis x of the holding surface H2a. Since the width is smaller than the width, the elastic restoring force that pushes back the rod-like portion B forward and releases the holding of the rod-like portion B in the holding state in which the connecting portion J is elastically stretched and deformed into a convex curved state toward the rear. Since it does not become too large, the holding state where the gripping body G grips the rod-shaped part B is A constant.

  In addition, the holding surface H2a has overhang portions H2b projecting in the rotation axis x direction from the connecting portion J on both sides in the rotation axis x direction. In a holding state in which a portion exceeding three laps is pressed and gripped by both holding portions H and the connecting portion J, the force that causes the rod-like portion B to be detached from the holding portions H and the connecting portion J in the axial direction (downward in FIG. 7) When applied, the protruding portions H2b opposite to the direction of the force for separating the holding portions H in the direction of the rotation axis x are elastic in the direction in which the rod-like portions B are fastened to each other (the direction of the arrow d in FIG. 7). Deformation can more effectively prevent the rod-shaped portion B from being removed in the axial direction.

  Further, the thickness of the connecting portion J is thinner than the thickness of the holding plate-like portion H2. Therefore, the elastic restoring force that pushes back the rod-like portion B forward and releases the holding of the rod-like portion B in the holding state in which the connecting portion J is elastically stretched and deformed in a convex curved state toward the rear is too large. Is prevented, and the holding state in which the grip body G grips the rod-shaped portion B is stabilized.

  As shown in the figure, the rod-shaped portion holder A is optimally used in a state where the rotation axis x direction of both holding portions H is the vertical direction, but the rotation axis of both holding portions H is not necessarily used. It is not necessary to set the x direction to the vertical direction. The rotation axis x direction may be set in the horizontal direction or set in a direction inclined with respect to the vertical direction.

  Further, the thickness of the connecting portion can be made equal to the thickness of the holding plate-like portion, or the material of the connecting portion can be made easier to expand and contract by making the elastic coefficient lower than that of the holding plate-like portion. Moreover, the whole holding | maintenance part can also be made wider than a connection part in the rotation axis direction width.

  In addition, the holding surface or the holding plate-like portion can be expanded in both or one direction than the connecting portion in the rotation axis direction. The ratio that the holding surface or the holding plate-like portion expands more than the connecting portion can be, for example, 1.1 to 3 times the width of the connecting portion. The ratio is preferably 1.2 to 2.5 times, more preferably 1.3 to 2.5 times, still more preferably 1.5 to 2 times. The shape of the holding surface or holding plate-like portion may be a circle, an ellipse, or other shapes in addition to a square whose one side direction is the rotation axis direction.

It is a perspective view. It is a top view. It is a front view. It is a side view. It is a perspective view of the state holding the rod-shaped part. It is a top view of the state holding the rod-shaped part. It is a front view of the state holding the rod-shaped part. It is a side view of the state which hold | maintained the rod-shaped part.
