Abstract

PURPOSE: To provide a lever handle for a door capable of being reliably and extremely easily installed without causing looseness according to a thickness between both sides in the lever handle respectively installed on both sides of the door. CONSTITUTION: As a square core member 6 is inserted into a through hole, a movable block 10 slides on a taper hole surface against springs 15, 17 by frictional force received from the square core member 6 to move in the arrow direction, and even if the square core member 6 inserted once into the through hole 14 is tried to be pulled out, since sandwiching force by the wedge action of an upper block 12 and a lower block 13 and energizing force by the springs 15, 17 for promoting this sandwiching force are imparted to the square core member 6, pulling-out becomes impossible. As the square core member 6 is inserted into a recessed hole through a bored hole and the through hole, a square core receiver 8 is spontaneously inserted into and fitted to an installing seat of a door, so that installation of a gripping part 3 is completed in a position for inserting no more.

Description

Lever handle for door

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever handle that is held by hand when opening and closing various doors, and more particularly, to a door lever handle that can facilitate mounting and dismounting of a door.

In the lever handle of this kind, there are various kinds of mounting structures for mounting the handle portions on both sides of the door, respectively.

As an example thereof, there is one disclosed in Japanese Patent Laid-Open No. 7-217267.

This lever handle 100 is provided with handles 102 and 103 respectively disposed on both sides of the lock box (fixed to the door or sliding door) 101, as shown in FIG. Is mounted by attaching the angular shaft 104 mounted with a small screw or the like with the shaft hole 105 of the handle portion 103 and twisting the fixing screw 106 therein. That is, one edge portion in the longitudinal direction of each axis 104 is sandwiched, and the two elongated coupling fixing plates 107 are joined to two adjacent surfaces 104a and 104b, respectively, so as to form a right angle. With respect to the coupling fixing plate 107 arranged in the form, the fixing screw 106 is twisted in to form a mounting structure in which the angular shaft 104 is fixed to the handle portion 103. 6A is a partial vertical plan view of the lever handle 100, and FIG. 6B is an enlarged cross-sectional view of A1-Al in FIG. 6A.

As another example, there is one disclosed in Japanese Patent Laid-Open No. 10-252321.

As shown in FIG. 7, the lever handle 200 is provided with the same handle portions 201 and 202, so that the core 203 mounted on the handle portion 201 may have an angle hole 204 of the handle portion 202. ), And the inserted core (203) can be supported by the stopper (205) in the inward direction of each hole (204). That is, in the space following the angular hole 204, a portion in contact with the core 203 is formed on the arc surface 205a (also shown in the case where teeth are formed on the arc surface). The stopper 205 in which the spring 206 is disposed is stored in the projection member 205b located on the side opposite to the circular arc surface 205a. When the core 203 is inserted into the corner hole 204, the core 203 is inserted. ) Pushes up the circular arc surface 205a which protrudes in the angular hole 204, whereby the stopper 205 rotates counterclockwise (the arrow direction in FIG. 7B) against the spring 206, Although the 203 can be inserted into the corner hole 204, even if the core core 203 is once inserted, the center core 203 is supported by the arc surface 205a in the inward direction of the corner hole 204. As it becomes the state to become, the attachment structure which cannot be pulled out is comprised. 7A is a perspective view of the lever handle 200, and FIG. 7B is an enlarged cross-sectional view A2 of FIG. 7A.

By the way, in the lever handle according to the first example described above, the mounting structure of the two-handed part is to fix each shaft mounted on one handle part to the other handle part by twisting the fixing screw, thus providing a large fixing force on each shaft. Although it is preferable at the point which can be provided and can prevent rattling of each axis | shaft, it is cumbersome because it involves work to screw in with a set screw.

In addition, in the lever handle according to the following example, the mounting structure of the two-handed part does not twist, and when the core is inserted into each hole, one grip part with the core can be fixed to the other handle part. The mounting work is easy, but the fixing acts on the stopper by contacting the circular arc surface of the stopper with the core, and the frictional force based on the pressure thereof. It is assumed that the spring mounted on the stopper's protruding member is susceptible to deformation or sheet deflection due to the rocking of the stopper. It is presumed that assembly of these stoppers and springs in the space will not be easy. Moreover, although it has a structure which is easy to generate a rattling of each hole, there is a problem in that his prevention is not made.

By the way, when the mounting structure of the two-handed part is based on the coupling between the stopper and the core, the coupling is made at the position specified by a multiple of the pitch length, so that the tip of the core is in contact with the innermost corner of each hole. Even if it stops at the point where it stops, it does not necessarily correspond to the point where the stopper's teeth and the teeth of the center are combined, and it is necessary to pay attention to that it becomes a factor which causes a rattling of the center.

It is an object of the present invention to provide a lever handle for mounting on both sides of a door, which can be mounted reliably and very simply without causing rattling depending on the thickness of both.

In addition, it is an object of the present invention to provide a lever handle for a door that can be removed very easily in addition to the above object.

In order to solve the above problems, the door lever handle according to claim 1 of the present invention is provided with handles mounted on both sides of the door to open and close the door, the other of the elongated core member fixed to one of the handles A lever handle inserted into a perforation hole formed in the side handle portion and mounted on the door, among which a tapered hole surface connected to the perforation hole and forming a gradient gradually in the insertion direction of the core member is inserted into the through hole. A movable block which slides with insertion of a core member, and pressurizing means comprised of elastic bodies, such as a spring and rubber | gum, which resist the sliding movement of this movable block, is provided, and penetrates a core member through a movable block. When inserted into the hole, the movable block slides the tapered hole surface against the pressing means by the frictional force received from the core member, While moving in the direction in which the gradient of the wiper hole increases, while attempting to pull out the shim member inserted into the through hole, the shim member is provided with the insertion attachment force due to the wedge action of the movable block and the pressing force of the pressing means that promotes it As a result, extraction is impossible. In this case, if the core member and the through-hole into which it is inserted, for example, the knurling groove processing of a wood, increase the friction force and insertion force mentioned above, it is preferable.

According to the door lever handle according to such a structure, according to the thickness of the door which mounts this, it can mount reliably only by inserting a core member into the through-hole of a movable block through a perforation hole, and makes mounting work very simple In addition, the lever handle is based on the fitting of the taper to each other, and forms a structure that is hardly rattled by itself, and can withstand long-term use due to the aforementioned reasons.

By the way, when the structure of a movable block is divided into two, for example in the hole axis direction of the through-hole, the insertion adhesion force by the said wedge action increases, and it is preferable. In this case, it is a matter of course that the movable block can be configured only on one of the two movable blocks.

In addition, the cross-sectional shape of the core member is not limited to a polygon such as a quadrangle or a hexagon, but may have a circular one. In addition, although the cross-sectional shape of a through hole needs to consider the cross-sectional shape of a core member, it is common to make it rectangular.

In addition, the lever handle for a door according to claim 2 of the present invention has a tapered hole surface and a tapered surface of the movable block that slides the hole surface in a flat shape. The rattling around the axis in the longitudinal direction is preferably regulated.

In addition, the lever lever for a door according to claim 3 of the present invention has a recessed portion for inserting a tip portion of the core member protruding from the through hole in a handle portion of the side on which the core member is inserted. Similar to the invention according to item 2, rattling around the axis in the longitudinal direction of the core member is regulated, and furthermore, rattling of the left and right and upper and lower sides based on the axis is also preferable.

In addition, the lever handle for a door according to claim 4 of the present invention is an operation window for connecting to a tapered hole, by inserting an appropriate operation mechanism, to release the engagement of the core member coupled through the through hole of the movable block. An operation window for pressurizing the movable block is provided. An operation mechanism such as a driver is inserted into the operation window of the movable block to press the movable block in a direction in which the gradient of the tapered hole increases, whereby the core member passes through the through hole. It can be pulled out of the cage, thereby squeezing both hands easily.

An example of an embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, the door lever handle 1 according to the present exemplary embodiment includes handle parts 3 and 4 disposed on both sides of the door 2, respectively. By operating 4), the door 2 can be opened and closed by retracting the latch 5 which protrudes from the side end of the door 2 and engages with a recess (not shown) of the door rim.

As shown in FIG. 2, a detailed configuration of the lever handle 1 for the door may be described later with an elongated spherical core member (core member) 6 fixed to the handle part 3 formed on the handle part 4. The handles 3 and 4 are mounted on both sides of the door 2 so as to be inserted into the drilling holes 11a and the like, respectively. However, FIG. 2A is a partial front cross section of the handle 1 of FIG. 1, and FIG. 2B is a partial cross sectional view seen from the A-A direction of FIG. 2A.

That is, the handle part 3 is equipped with the shaft part 3a and lever handle part 3b which comprise substantially L-shape, and the side of the handle part 4 of the shaft part 3a which opposes the following shaft part 4a. In the end face, the center receiving portion 8 for mounting the handle 3 on the door 2 protrudes, while the center receiving portion 8 inserts the centering member 6 into the angle receiving portion 8. It is perforated. And in the state connected to this square hole 8a, the recessed hole 9 for inserting the core member 6 is drilled in the shaft part 3a, and the core member 6 is a recessed hole 9 and It is fixed to the corner hole 8a with a screw or the like, and protrudes from the corner hole 8a so as to be connected to the shaft portion 4a of the handle portion 4. By the way, in this embodiment, the flat-knurling process is given to the side surface 6a of the extension part of the core member 6, and the side surface (not shown) located on the opposite side to the said side surface 6a (refer FIG. 2B). .

Moreover, the handle part 4 is equipped with the said shaft part 4a and the lever handle part 4b which comprise the substantially L shape of the same shape as the handle part 3, and the handle part 3 of the shaft part 4a is provided. The fixing block 11 for sliding the movable block 10 mentioned later protrudes, while attaching the handle part 4 to the door 2 in the cross section which opposes the shaft part 3a of this, In the shaft portion 4a, a concave hole 7 for inserting the distal end portion 6b of the core member 6 is formed to face the connecting hole 11c, which will be described later, of the fixing block 11. By (7), the rattling around the axis | shaft which makes the longitudinal direction of the core member 6 the axis | shaft is regulated, and the rattling of the right and left and the upper and lower sides based on the said axis | shaft is regulated.

By the way, this fixing block 11 forms a large cylindrical shape as shown in FIG. 3, The above-mentioned drilling hole 11a for inserting the core member 6 is drilled in this cylinder, and this drilling hole In the state connected to 11a, in addition, the above-mentioned taper hole 11b is drilled in such a form that the gradient thereof increases in the insertion direction (arrow direction in FIG. 5B) of the core member 6, and furthermore, this taper hole The communication hole 11c following 11b is drilled. 3A is a front cross section of the fixing block 11, FIG. 3B is a b perspective view of FIG. 3A, and among these figures, 11d is a corresponding shaft portion 4a when the fixing block 11 is arranged on the shaft portion 4a. 11e is a hole in which a fixing pin (not shown) is inserted to fix the fixing block 11 to the shaft portion 4a.

Here, the movable block 10 which slides in the fixed block 11 will be described in detail with reference to FIG. 4. 4A is a front view of the movable block 10, FIG. 4B is a C perspective view of FIG. 4A, and FIG. 4C is a D perspective view of FIG. 4A.

The movable block 10 has a configuration divided into two in this embodiment, that is, the upper block 12 shown in Fig. 4 and the same shape as this, and arranged in the form as shown in Fig. 2. It consists of the lower block 13, and these blocks 12 and 13 are formed so that the spherical through-hole 14 is formed, and these blocks 12 and 13 pass through the tapered surfaces 12a and 13a. In accordance with the insertion of the core member 6 into the through hole 14, the surface of the tapered hole 11b is integrated and slides.

By the way, in the present embodiment, the tapered hole 11b and the tapered surface 12a of the upper block 12 engaged with the tapered hole 11b are formed in a flat surface and connected to and connected to the tapered surface 12a to guide the surface 12b. Is formed (not shown, but the same also applies to the lower block 13), thereby restricting rattling of the core member 6 around the axis in the longitudinal direction thereof, and shaking around the axis. This will not occur. In addition, the through-hole 14 is subjected to the flat wood knurling process corresponding to the side surface 6a of the core member 6 mentioned above and the side surface located on the opposite side to the side surface 6a (refer FIG. 4C). Moreover, the convex part 16 for attaching the spring 15 mentioned later protrudes in the cross section of the block 12 on this upper side (it is not shown but the same also about the lower block 13). Each of the spring (pressing means) 15 of the upper block 12 and the spring (pressing means) 17 of the lower block 13 has one end thereof mounted to the shaft portion 4a, and the movable block 10 The gradient of the taper hole 11b of () is arrange | positioned in the form which resists sliding movement in an increasing direction. In the present embodiment, the springs 15 and 17 are arranged with respect to the blocks 12 and 13, respectively, but one spring may be arranged with respect to the blocks 12 and 13.

By the way, each hole 18 which connects to the taper hole 11b is formed in the shaft part 4a of the handle part 4, and the fixing block 11, respectively (not shown in each hole of the shaft part 4a). While the operation window is formed by these square holes 18 and the like, notch grooves 19 and 20 are formed in the upper block 12 and the lower block 13, respectively, and the squares are formed by these notch grooves 19 and 20. The slit of the top is formed in the form which connects to the said operation window (FIG. 2A). Thereby, for example, when the operation mechanism such as a driver is inserted into the operation window, and the movable block 10 is pressed by the operation mechanism inserted into the slit, the through hole 14 of the movable block 10 Since the coupling of the core member 6 coupled through is released, the core member 6 can be easily pulled out.

Next, the mounting and dismounting of the handle 1 will be described with reference to FIG. 5. 5A shows the case where the core member 6 is inserted into the punched hole 11a or the like on the handle 4 side, and FIG. 5B shows the case where the core member 6 is inserted into the drilled hole 11a or the like. It is explanatory drawing which shows.

Before mounting, the handle part 4 is previously attached to one attachment sheet (not shown) of the door 2 via the fixing block 11. Then, the core member 6 (actually, the handle portion 3 on which the core member 6 is fixed) is placed facing each other as shown in FIG. 5A in order to insert the drill hole 11a or the like. Then, the core member 6 is inserted in the drilling hole 11a or the like little by little or at a time as shown in Fig. 5B.

In this way, the core member 6 is inserted into the through hole 14 of the movable block 10 through the drilling hole 11a. However, as the core member 6 is inserted into the through hole 14, the movable block 10 is spring 15, 17 by the frictional force received from the core member 6 through the through hole 14. The taper hole 11b surface is slid in response to the resistance, and the taper hole 11b is slid to move in the direction in which the gradient thereof increases (in the arrow direction in FIG. 5B). According to this movement, it goes without saying that the upper block 12 and the lower block 13 of the movable block 100 form a form separated from each other.

By the way, even if the core member 6 inserted into the through hole 14 is to be pulled out, the core member 6 has an insertion adhesion force due to the wedge action of the upper block 12 and the lower block 13, and encourages this. Since the pressing force by the springs 15 and 17 to apply is given, extraction is impossible. By the way, even when the core member 6 is inserted or removed, the tapered surfaces 12a and 13a of the movable block 10 always slide in contact with the tapered holes 11b of the fixed block 11. Needless to say.

And when the core member 6 is inserted into the recessed hole 7 through the perforation hole 11a and the through-hole 14 in this way, the core center accommodating part 8 automatically attaches the sheet | seat of the door 2 (shown). Not inserted), and the insertion of the handle part 3 is completed at the position at which insertion was impossible. Therefore, the mounting worker can reliably mount only by inserting the core member 6 into the hole 11a or the like without worrying about the thickness of the door 2.

Moreover, when removing the attached handle parts 3 and 4, when a driver is inserted from the said operation window, and the movable block 10 is pressurized by the operation mechanism inserted in the said slit in the direction of an arrow in FIG. 5B, Since the movable block 10 moves in the corresponding direction and the core member 6 coupled through the through hole 14 is released, the core member 6 can be easily removed from the through hole 14. The two-handed parts 3 and 4 can be separated easily.

In the above-described embodiment, the case in which the movable block 10 is composed of an upper block 12 and a lower block 13 divided into two parts has been described. However, in some cases, the movable block 10 is replaced by the upper block 12 only. Of course, it can be configured.

According to the lever handle for a door of this invention, it becomes the lever handle attached to both sides of a door, and can be mounted reliably and very simply, without creating a rattling according to the thickness between both sides.

In addition, according to the door lever handle of the present invention, the lever handle attached to the door can be removed very easily.
