Japanese Unexamined Patent Publication No. 2015-224670

In the above-mentioned fixing device, since the knob, which is an operation unit for releasing the fixing, protrudes from the main body, a wide movement path of the main body is secured so that the knob does not collide with surrounding objects when the moving body moves. There is a problem that it is necessary.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a fixing device capable of suppressing protrusion of a moving body from a moving path.

Hereinafter, means for solving the above problems and their actions and effects will be described.
The fixing device that solves the above problems is a fixing device that fixes a moving body that can move along the guide portion to the guide portion, and the guide portion is inclined so as to approach the guide portion as the distance from each other increases. Two fixing members extending along the above, two fixing members provided corresponding to the two inclined portions, and sandwiching between the inclined portion and the guide portion to fix the moving body, and two The urging members that urge the fixing members in a direction away from each other and the urging members provided on both ends of the moving body in the moving direction are moved in a direction approaching each other against the urging force of the urging members. It includes two pressing members that press the fixing member to release the fixing of the moving body.

According to this configuration, the fixing of the moving body can be released by moving the two pressing members in the directions approaching each other. Then, since the two pressing members are provided on both ends in the moving direction of the moving body, the pressing members operated for releasing the fixation are arranged in the moving path of the moving body, and from the moving path of the moving body. Can be suppressed from protruding.

In the fixing device, the fixing member is a rollable rolling element, the pressing member has a through hole for rotatably accommodating the fixing member, and the two pressing members are formed in the through hole. It is preferable that the accommodated fixing member is sandwiched between the inclined portion and the guide portion to restrict movement in a direction away from each other.

According to this configuration, when the fixing member is accommodated in the through hole, the pressing member and the fixing member move in conjunction with each other. Therefore, by sandwiching the fixing member between the inclined portion and the guide portion, the movement of the two pressing members in the direction away from each other is restricted. As a result, the pressing member can be integrated with the moving body.

In the fixing device, the urging member is a compression spring arranged in a compressed state between the two pressing members, and it is preferable to urge the fixing member via the pressing member.

According to this configuration, a compression spring is arranged between the two pressing members, and the urging force of the urging member is applied to the fixing member via the pressing member, whereby the urging member and the peripheral surface of the fixing member are formed. It is possible to suppress the sliding contact of.

In the fixing device, the urging member is an elastic body that can be elastically deformed, and when the two pressing members move in a direction approaching each other and release the fixing, the urging member comes into contact with the pressing member and moves. It is preferable to provide a blocking wall portion for stopping.

According to this configuration, when the two pressing members approach each other and release the fixation of the moving body, the restraining wall portion stops the movement of the pressing member, thereby controlling the pressing force exerted by the pressing member on the urging member. Therefore, the urging member, which is an elastic body, can be adjusted so as to be deformed within the elastic limit.

It is preferable that the fixing device includes a wire that draws one of the two pressing members in a direction approaching the other, and the two pressing members are provided with an insertion hole through which the wire is inserted.

According to this configuration, when a wire is pulled through the insertion holes provided in the two pressing members, one pressing member pulled by the wire moves so as to approach the other pressing member, so that the fixing is released. .. Therefore, if the wire is pulled at a position away from the moving body, the fixing can be released by remote control. Further, by passing the wire through the insertion hole of the pressing member, the member for remote control can be efficiently arranged.

According to the present invention, it is possible to suppress the protrusion of the fixing device from the moving path of the moving body.

Hereinafter, a fixing device according to an embodiment embodying the present invention will be described with reference to the drawings.
As shown in FIG. 1, the fixing device 30 is a device that fixes a moving body 21 that can move along the guide portion 10 to the guide portion 10. The fixing device 30 of the present embodiment is mounted on the moving body 21, and moves along with the moving body 21 along the guide portion 10. The moving body 21 can move in both the first moving direction D1 toward one end side in the longitudinal direction D of the guide portion 10 and the second moving direction D2 toward the other end side.

Even if the guide unit 10 is a guide rail that guides the slide movement of the drawer or the table when the drawer mounted on a desk or the like or the telescopic hood tray (table) provided on the seat of the vehicle is taken in and out. Good. Further, the guide unit 10 may guide the vertical movement of the microscope table, the operation panel of the machine tool, the armrest attached to the seat, and the like when adjusting the height. In addition, the guide unit 10 may guide the opening and closing of a sliding door such as a sliding door. Further, an object to be moved along the guide portion 10 (for example, a drawer, a table, an armrest, a sliding door, etc.) may be connected to the moving body 21. The object can be fixed to the end surface 21b of the moving body 21 by screwing or the like, for example.

As shown in FIG. 1, the guide portion 10 of the present embodiment has a guide surface 11 extending in the longitudinal direction D and a pair of engaging recesses 12 extending along the outer edge of the guide surface 11 in the lateral direction W. The moving body 21 has a pair of engaging convex portions 22 that engage with the engaging concave portions 12, and the engaging convex portions 22 can move along the guide surface 11 by engaging with the engaging concave portions 12. It is attached to the guide portion 10 in an embodiment. The concave-convex relationship between the guide portion 10 and the moving body 21 may be reversed, and the guide portion 10 may be provided with an engaging convex portion and the moving body 21 may be provided with an engaging concave portion to engage the two.

As shown in FIG. 2, the fixing device 30 includes two inclined portions 31 extending along the guide portion 10, two fixing members 33 provided corresponding to the two inclined portions 31, and two fixing members 33. It is provided with an urging member 34 that urges the moving body 21 in a direction away from each other, and two pressing members 35 provided on both end sides of the moving body 21 in the moving directions D1 and D2.

With reference to the reference line Ld that divides the moving body 21 in the longitudinal direction D, the inclined portion 31, the fixing member 33, and the pressing member 35 located on the left side of the reference line Ld in FIG. 3 form the first fixing mechanism 30F. In FIG. 3, the inclined portion 31, the fixing member 33, and the pressing member 35 located on the right side of the reference line Ld constitute the second fixing mechanism 30S. The first fixing mechanism 30F regulates the movement of the moving body 21 in the first moving direction D1 (to the right in FIG. 3) and releases the regulation (fixing), and the second fixing mechanism 30S moves. The movement of the body 21 in the second movement direction D2 (left in FIG. 3) is restricted and the restriction (fixed) is released.

The two inclined portions 31 are arranged at positions separated from each other in the longitudinal direction D, and are inclined so as to approach the guide portion 10 as they are separated from each other. The fixing member 33 has a circular cross section such as a cylindrical shape, a cylindrical shape, a spherical shape, or an elliptical spherical shape so as to reduce friction when sliding with respect to the guide portion 10. It is preferably a moving body. The fixing member 33, which is a rolling body, fixes the moving body 21 to the guide portion 10 by being sandwiched between the inclined portion 31 and the guide portion 10. Specifically, when the moving body 21 tries to move in the first moving direction D1, the fixing member 33 is sandwiched between the inclined portion 31 and the guide portion 10 in the first fixing mechanism 30F, and the moving body 21 first moves. Movement in direction D1 is restricted. Further, when the moving body 21 tries to move in the second moving direction D2, the fixing member 33 is sandwiched between the inclined portion 31 and the guide portion 10 in the second fixing mechanism 30S, and moves to the second moving direction D2 of the moving body 21. Movement is restricted.

The inclined portion 31 may be, for example, an inclined surface composed of one surface of the plate member 32 embedded in the moving body 21. The inclined portion 31 can be integrally formed as a part of the moving body 21, but is composed of a plate member 32 made of a hard material so as not to be deformed or worn when the fixing member 33 is pinched. Is preferable. Further, similarly, two inclined portions 31 may be formed on a hard plate member, and the plate member may be embedded in the moving body 21.

As shown in FIG. 3, the two pressing members 35 move in a direction approaching each other against the urging force of the urging member 34, so that the fixing member 33 sandwiched between the inclined portion 31 and the guide portion 10 Is pressed toward the reference line Ld to release the fixing of the moving body 21. For example, when the thumb and the index finger are attached to the two places indicated by the white arrows in FIG. 3 and the two pressing members 35 are moved toward each other along the guide surface 11, the moving body 21 is released from being fixed. To. The position when the pressing member 35 is released from being fixed (the position shown in FIG. 3) is referred to as the release position, and the position of the pressing member 35 when the moving body 21 is fixed (the position shown in FIG. 2) is referred to as the fixed position. ..

If the moving body 21 that has been released from being fixed is gripped so that the two pressing members 35 are fixed at the fixed positions, the moving body 21 is manually moved in the first moving direction D1 and the second moving direction D2 along the guide portion 10. be able to. Further, if the moving body 21 is moved to an arbitrary position and then the hand is released from the pressing member 35, the pressing member 35 returns to the fixed position by the urging force of the urging member 34. Therefore, the moving body 21 can be quickly fixed to the guide portion 10 without performing a separate fixing operation.

The two pressing members 35 form a fixing mechanism that regulates movement in different moving directions D1 and D2. Therefore, if only the pressing member 35 toward the first fixing mechanism 30F is pressed in the first moving direction D1 by, for example, gripping the moving body 21, the movement of the moving body 21 in the second moving direction D2 is restricted. In this state, the moving body 21 can be moved in the first moving direction D1. Similarly, if only the pressing member 35 of the second fixing mechanism 30S is pressed in the second moving direction D2, the moving body 21 is seconded in a state where the movement of the moving body 21 in the first moving direction D1 is restricted. It can be moved in the moving direction D2.

As shown in FIG. 4, the moving body 21 may be provided with a pair of guide walls 23 for guiding the movement of the pressing member 35 along the guide surface 11. Further, the pressing member 35 may be provided with a protruding portion 36 projecting in the thickness direction T so as to be easily pinched. However, it is preferable that the protruding portion 36 does not protrude in the thickness direction T from the end surface 21b of the moving body 21 (see FIGS. 2 and 3).

When the two pressing members 35 move in a direction approaching each other to release the fixation, a part of the pressing member 35 (for example, the protruding portion 36) comes into contact with the moving body 21 and cannot move any further. It is preferable to be stopped as such. In the present embodiment, both ends of the moving body 21 in the longitudinal direction D are stop wall portions 24 for stopping the movement of the pressing member 35 that has been released from fixing. The restraining wall portion 24 may be provided in the fixing device 30 as a member separate from the moving body 21.

When the two pressing members 35 come into contact with the restraining wall portion 24, the two pressing members 35 sandwich the moving body 21, so that the operation of pinching the pressing member 35 to release the fixing and the movement of releasing the fixing are performed. The operation of moving the body 21 can be continuously performed. Further, by contacting the restraining wall portion 24, the movement of the pressing member 35 related to the release of the fixing can be minimized, so that the labor and time for releasing the fixing can be reduced.

The pressing member 35 preferably has a through hole 37 that rotatably accommodates the fixing member 33 which is a rolling element. In this way, the fixing member 33 can be moved together with the pressing member 35. Further, in this way, the two pressing members 35 fall out of the moving body 21 because the fixing member 33 is sandwiched between the inclined portion 31 and the guide portion 10 to restrict the movement in the direction away from each other. There is no.

The urging member 34 can be an elastic body that can be elastically deformed. For example, a compression spring arranged in a compressed state between two pressing members 35 is referred to as an urging member 34. Then, the urging member 34 urges the fixing member 33 via the pressing member 35. Since the fixing member 33 is configured to be sandwiched between the inclined portion 31 and the guide portion 10 by an external force acting on the moving body 21 (a force for moving the moving body 21), the urging member 34 tilts the fixing member 33. It suffices if there is enough urging force to lightly press against the portion 31.

The pressing member 35 may be provided with a locking recess 38 for locking the end of the urging member 34. As a result, the posture of the urging member 34 can be stabilized. Further, the urging member 34 may be provided in a plurality (for example, three) or only one depending on the width (length in the lateral direction W) of the pressing member 35 or the fixing member 33.

Next, the operation of the fixing device 30 configured as described above will be described.
In the fixing device 30 incorporated in the moving body 21, the pressing members 35 operated when releasing the fixing of the moving body 21 are provided on both ends of the moving body 21 in the moving directions D1 and D2, and thus are provided from the moving body 21. It can be arranged so as not to protrude in the thickness direction T. As a result, the dimension of the fixing device 30 in the thickness direction T can be reduced to reduce the thickness.

Further, even if the fixing device 30 is thin, the two pressing members 35 arranged so as to sandwich the moving body 21 can be operated so as to be pinched from both sides in the longitudinal direction D, so that the size of the operating portion can be increased. Therefore, the operability at the time of releasing the fixing or moving the released moving body 21 is good.

According to the above embodiment, the following effects can be obtained.
(1) By moving the two pressing members 35 in a direction approaching each other, the moving body 21 can be released from being fixed. Since the two pressing members 35 are provided on both ends of the moving body 21 in the moving directions D1 and D2, it is possible to suppress the protrusion of the moving body 21 from the moving path. Therefore, even if the pressing member 35 is provided as an operating portion for releasing the fixation of the moving body 21, it is not necessary to expand the moving path for the operating portion.

(2) When the fixing member 33 is housed in the through hole 37, the pressing member 35 and the fixing member 33 move in conjunction with each other. Therefore, by sandwiching the fixing member 33 between the inclined portion 31 and the guide portion 10, the movement of the two pressing members 35 in the direction away from each other is restricted. As a result, the pressing member 35 can be integrated with the moving body 21.

(3) An urging member 34, which is a compression spring, is arranged between the two pressing members 35, and the urging force of the urging member 34 is applied to the fixing member 33 via the pressing member 35 to cause the urging member 33. The sliding contact between the 34 and the peripheral surface of the fixing member 33 can be suppressed. Therefore, it is possible to avoid a situation in which the fixing member 33 is damaged or deformed due to the sliding contact with the urging member 34, which increases the frictional resistance with respect to the guide portion 10 and hinders the movement of the pressing member 35. it can.

(4) When the two pressing members 35 approach each other and release the fixation of the moving body 21, the pressing member 35 exerts the pressing force on the urging member 34 by stopping the movement of the pressing member 35. Can be adjusted so that the urging member 34, which is an elastic body, is deformed within the elastic limit. As a result, the load applied to the urging member 34 due to the pressing of the pressing member 35 can be reduced.

(Change example)
The above embodiment may be modified as in the modification shown below. Further, each configuration included in the above embodiment and each configuration included in the following modification example may be arbitrarily combined, or each configuration included in the following modification example may be arbitrarily combined. In the following description, components having the same functions as those described above will be designated by the same reference numerals, and duplicate description will be omitted.

As in the first modification shown in FIG. 5, the fixing device 30 engages with a wire 41 that pulls one of the two pressing members 35 in a direction approaching the other and a base end of the wire 41 with one pressing member 35. The operation mechanism 40 may include a locking member 42 for stopping and a regulating portion 43 for restricting the movement of the other pressing member 35 when the one pressing member 35 is attracted. The regulation unit 43 can be, for example, a tubular member through which the wire 41 can pass. Also in the above embodiment, as shown by the alternate long and short dash line in FIG. 2, the wire 41, the locking member 42, and the regulating portion 43 can be arranged. In this case, as shown in FIGS. 2 and 5, it is preferable that the two pressing members 35 are provided with an insertion hole 39 through which the wire 41 is inserted, and the moving body 21 is provided with an insertion hole 29 through which the wire 41 is inserted.

According to this configuration, when the wire 41 is pulled through the insertion holes 39 provided in the two pressing members 35, one pressing member 35 pulled by the wire 41 moves so as to approach the other pressing member 35. , The fixing is released. Therefore, if the wire 41 is pulled from a position away from the moving body 21, the fixing can be released by remote control. Further, by passing the wire 41 through the insertion hole 39 of the pressing member 35, the operation mechanism 40 for remote control can be efficiently arranged in the movement path of the moving body 21.

As shown by the alternate long and short dash line in FIG. 5, an extension portion 35a extending from the pressing member 35 in the lateral direction W may be provided, and an insertion hole 39 may be provided in the extension portion 35a to allow the wire 41 to pass through. In this case, the moving body 21 does not have to be provided with the insertion hole 29.

As shown in the first modification of FIG. 5, the guide portion 10 may be a thin plate thinner than the moving body 21. In this case, the moving body 21 has an insertion portion 44 through which the guide portion 10 can be inserted, instead of the engaging convex portion 22 of the above embodiment. The insertion portion 44 can be formed by making a hole in the moving body 21, or can be formed by attaching another engaging member 45 to the moving body 21 having the guide wall 23 with a screw or the like.

An object to be moved along the guide portion 10 (for example, a drawer, a table, an armrest, a sliding door, etc.) may be directly fixed to the end face 21b of the moving body 21, or may be fixed to the moving body 21 via another member. It may be fixed to 21.

For example, as in the second modification shown in FIG. 6 or the third modification shown in FIG. 7, another moving body 51 having a pair of engaging protrusions 52 that engage with the engaging recess 12 of the guide portion 10 is provided. The moving body 21 attached to the guide portion 10 and integrated with the fixing device 30 is connected to another moving body 51 by a connecting member 53. The connecting member 53 may have an engaging protrusion 54 that engages with the end portion of the moving body 21 in the longitudinal direction D in order to interlock the movement of the moving bodies 21 and 51 along the longitudinal direction D. Further, the connecting member 53 may have a shape that does not hinder the movement of the pressing member 35.

Here, when the fixing device 30 releases the fixing, the fixing member 33 sandwiched between the inclined portion 31 and the guide portion 10 pushes the moving body 21 in the thickness direction T so that the moving body 21 is lifted from the guide portion 10. It may be displaced to. If such a displacement is transmitted to the moving body 51 via the connecting member 53, the position of the object fixed to the moving body 51 may shift.

Therefore, like the connecting member 53 shown in FIG. 6, an engaging protrusion 54 is provided at the tip of the extending portion 55 extending along the both side surfaces 21a extending in the longitudinal direction D of the moving body 21, and intersects the both side surfaces 21a. When the end face 21b is opened in a displaceable manner, the object fixed to the end face 53b of the connecting member 53 or the like is not easily affected by the displacement of the moving body 21.

Alternatively, as shown in FIG. 7, a thin plate-shaped connecting member 53 that can be flexed and displaced with the displacement of the moving body 21 is fixed to the end surface 21b (see FIG. 6) of the moving body 21 with a fixing tool 56 such as a screw. The laminated member 57 is laminated on the moving body 51 so as to sandwich the connecting member 53. Then, the laminated member 57 is set to protrude from the fixture 56 in the thickness direction T, and the object is fixed to the end surface 57b of the laminated member 57. According to this configuration, even if the thin plate-shaped connecting member 53 is bent so as to float in the thickness direction T, the displacement of the object can be suppressed.

In the second modification shown in FIG. 6 or the third modification shown in FIG. 7, the guide portion 10 can be made into a thin plate thinner than the moving body 21 as in the first modification (see FIG. 5).
In the walker 60 shown in FIG. 8, a part of the support columns 63 extending from the pair of support plates 62 that rotatably hold the wheels 61 may be used as the guide portion 10. In this case, the fixing device 30 can be used to fix the position of the handrail 64 that is height-adjustably attached to the support column 63. In addition to the handrail 64, if an elbow holder for placing an elbow on the walker 60, a handle for changing the traveling direction, a seat for sitting, a car for storing luggage, etc. are provided with adjustable height, their positions are fixed. The fixing device 30 may be used. Similarly, in addition to the walker 60, when adjusting the length and position of handrails, handles, handles, handles, etc. of carts, carry backs, strollers, stretchers, etc. that carry luggage, they are fixed to fix them. The device 30 may be used.

When the fixing devices 30 are attached to the paired guide portions 10, they may be attached in a manner in which they can be individually operated as shown in FIGS. 8 and 9, or the wires 41 shown in FIG. 5 are used to form a pair. The fixing release and fixing operations of the two fixing devices 30 may be performed at the same time. For example, the wires 41 extending from the two fixing devices 30 are arranged along the handrail 64, and an operation unit (not shown) including a lever or a button is provided in an intermediate portion (for example, one central location) of the handrail 64. .. Then, the wire 41 may be pulled by the operation of the operation unit to simultaneously release the fixing of the two paired fixing devices 30. Alternatively, operating units connected to the wires 41 extending from the two fixing devices 30 may be provided at two locations on the handrail 64, and the fixing may be released individually.

-As shown in FIG. 9, the pressing member 35 of the fixing device 30 may be provided with a recess 35b on which a finger is hung.
As in the fourth modification shown in FIGS. 9 and 10, the engaging member 45 is attached to the moving body 21 with screws or the like, and the guide portion 10 (post) is attached to the insertion portion 44 formed between the engaging member 45 and the engaging member 45. 63) may be passed. According to this configuration, the fixing device 30 can be applied to various guide portions 10 by changing the shape of the engaging member 45 according to the size and shape of the guide portion 10.
