In describing the bowling ball shock absorber for a bowling alley according to the present invention, when an unambiguous approximate direction reference is specified with reference to FIG. 1, a direction in which gravity acts is referred to as a direction in which the lane is installed, Downward, leftward, and rightward as viewed in the downward direction, and directions are specified in accordance with this standard unless otherwise specified in the detailed description and claims of the invention relating to other drawings.

Hereinafter, a bowling ball shock absorber for a bowling ball according to the present invention will be described with reference to the accompanying drawings.

1 to 4, a bowling ball shock absorber for a bowling alley according to the present invention mainly includes a frame member 10 connected to a rear end of a lane L to form a pit, A cushioning member 20 and a cushioning membrane 30 which are arranged in a front and a back of the member 10 and a floor 40 forming a bottom portion of the frame member 10.

In this specification, a bowling ball shock absorber installed in a screen bowling alley will be described as an example, but the present invention may be installed in a pit of a general bowling alley in some cases, and therefore the right interpretation of the present invention should not be limited.

The frame member 10 is formed by assembling the horizontal and vertical frames in a box shape to form a bowling hole recovery area (pit in a general bowling alley) of the lane L. The frame member 10 includes a front first fixed And includes a frame 11 and a rear second fixed frame 12.

At this time, the first fixing frame 11 is provided at a higher height than the second fixing frame 12.

In the figure, the first fixed frame 11 is connected to a separate vertical frame on both upper side horizontal frames of the frame member 10, and the upper upper horizontal frame of the frame member 10 is used as the second fixed frame 12 Thus, it can be seen that the first fixing frame 11 is provided higher than the second fixing frame.

In this frame member 10, a separate projection film may be provided on the front end entrance side of the pit to project a bowling pin, or a bowling pin may be projected or printed on the front surface of the buffer member 20, As an example for describing the imaging of the pins, various methods used in the known screen bowling alleys can be applied to the frame member 10, and when installed in a general bowling alley, the frame member 10 forms only a pit .

The cushioning member 20 allows the bowling hole B of the bowling ball B to be recovered after the primary cushioning. The upper end of the bowling hole B is hinged to the first fixing frame 11 to rotate back and forth. And a cushion portion 21 made of a flexible material to absorb the impact of the bowling hole B.

Specifically, the buffer member 20 includes a mattress-type cushion unit 21, a frame-type fixing frame 22 made of a hard material and coupled to an upper end of the rear surface of the cushion unit 21, And a cover 23 for covering the entire body.

The cushion part 21 includes a flexible memory foam or a flexible synthetic resin such as rubber, silicone, polyurethane, rubber, cotton or other soft synthetic resin so that the shape of the cushion part 21 itself Absorbs the impact of the bowling ball (B) through displacement.

Of course, the cushion portion 21 may have a structure similar to that of a mattress for a bed having elastic means such as a spring incorporated therein.

The fixed frame 22 is made of a hard material such as general metal or wood and has a rectangular shape. More preferably, the fixed frame 22 is made of 1/2 to 2/3 of the total area of the cushion portion 21, Is supported on the fixed frame 22. [0050]

Such a fixed frame 22 imparts rigidity to the cushion portion 21 itself and more precisely to a portion of the upper end of the cushion portion 21 so that the cushion portion 21 is deformed by the bowling hole B, The cushioning portion 20 is prevented from being damaged by the impact of the cushion portion 21 itself and the cushioning member 20 by the backward rotation of the cushioning portion 20, .

The cover 23 covers and protects the entire outer surface of the cushion 21 and the fixing frame 22 so that when the front surface is contaminated or broken, only the cover 23 can be easily replaced and used.

The cushioning member 20 having such a configuration is hinged to the first fixing frame 11 through various kinds of hinge means so that the cushioning member 20 ) Absorbs the impact of the bowling ball (B), and then returns to its forward position by its own weight.

In the drawing, hinges 24 for connecting the first fixing frame 11 and the back surface of the buffer member 20 are representatively shown as hinge means.

The buffer film 30 is coupled to the second fixing frame 12 at its upper end and is made of a soft material and absorbs the impact of the buffer member 20 while contacting the buffer member 20 rotating backward.

The buffering layer 30 is made of a rubber plate, a nonwoven fabric, a mesh-like netting film, or other soft synthetic resin material. The buffering layer 30 has a thin cloth shape. The buffering layer 30 is disposed to be positioned within a minimum rotation range of the buffering member 20, The cushioning member 20 is brought into contact with the entire surface of the cushioning membrane 30 so that the shock of the cushioning member 20, that is, the impact of the bowling hole B, is absorbed secondarily.

The buffer layer 30 can minimize the angle at which the buffer layer 20 rotates backward and reduce the buffer layer 20 impacted by the material properties of the buffer layer 30 to the buffer layer 30 The buffer member 20 is momentarily decelerated to return to its original position.

The lower end of the buffer film 30 is fixed to the lower portion of the floor 40 at the same position as the second fixing frame 12.

That is, the first and second fixed ends 31 and 32 are fixed to the upper and lower ends of the buffer film 30 in a direction perpendicular to the second fixed frame 12, respectively, The buffer film 30 is fixed without flapping.

At this time, the total height of the buffer film 30 is formed to be longer than the installation height of the second fixing frame 12, so that the buffer film 30 protrudes rearward by the back sheet 41 to be described later.

This is because when the buffer film 30 is provided in a state of being simply upright in the vertical direction with the same height as that of the second fixing frame 12, the buffer film 30 can not secure an allowance for covering the buffer film 30, The pressure applied by the buffer member 20 is increased to prevent the buffer film 30 from being easily torn,

Particularly, since the cushioning membrane 30 of the present invention extends over the discharge plate 41 in such a form that the upper end portion thereof is inclined downward to the rear side, the cushioning member 20, which is rotating backward, The cushioning member 20 and the cushioning membrane 30 are brought into contact with each other to instantaneously decelerate the returning of the cushioning member 20 after the shock is absorbed to the cushioning member 20 while minimizing the rotation angle of the cushioning member 20 .

The floor 40 is installed in the inner space of the frame member 10 so as to have a lower height than the lane L to form a bottom in the collection space of the bowling hole B. [

The floor 40 has a front plate 40A connected to the end of the lane L and an upper space of the floor 40 is connected to a gutter provided on both sides of the lane L and the lane L. [ The bowling hole B is rolled into the bowl 40 by the bowl 43 connected to the bowling ball collecting device after the used bowling hole B is dropped on the upper surface of the floor 40 .

Specifically, the floor 40 includes a discharge port 41 formed to be inclined downwardly toward the one-side recovery path 43, and a ditch having a lower height than the front end of the discharge port 41 at the front end of the discharge port 41 And a discharge passage (42) formed horizontally so as to have a shape and having a bottom portion (42a) inclined downward toward the one - side recovery passage (43).

That is, one end of the front end of the discharge tray 41 is formed lower than the other edge of the rear end of the discharge tray 41 so as to be inclined toward the front side with the collecting passage 43 as a whole, 42a are formed lower than the other end and are inclined in one direction with the collecting passage 43 as a whole.

The cushioning member 20 has a lower inclined surface 20a which is inclined upwards from the other end of the cushioning member 20 toward the one end of the cushioning plate 20 corresponding to the inclination of the backing plate 41, So that the cushioning member 20 does not come into contact with the discharge plate 41 when the cushioning member 20 is rotated forward and backward.

Therefore, according to the present invention, when the bowling ball B enters the pit area through the lane L or the gutter, the bowling ball B collides against the cushioning member 20, The cushioning member 20 is rotated to the rear side to firstly eliminate the impact of the bowling hole B and the cushioning member 20 is brought into contact with (collided with) the buffer film 30 at the rear The impact of the bowling hole B is secondarily eliminated and the rotation of the bowling hole B is temporarily stopped by the buffer film 30 before returning to push the bowling hole B toward the front side. And the discharge path 42 toward the recovery path 43 and recovered through the bowling ball collecting machine.

The present invention can be applied to a bowling ball (20) with a double-cushioning structure (more precisely, a triple cushioning structure including a cushioning portion (21) and a cushioning structure of the cushioning member (20)) of the cushioning member B to prevent the bowling ball B from bouncing over the lane L again and the bowling ball B seated on the floor 40 lower than the lane L is prevented from returning to the lane L, It is possible to naturally roll and discharge the bowling ball B toward the recovery path 43 due to the pressing of the member 20 and the inclination of the discharge plate 41 and the discharge path 42,

Furthermore, the back sheet 41 is provided such that the rear end thereof is positioned behind the second fixing frame 12, and the buffer film 30 is provided so as to protrude rearward by the back sheet 41.

That is, the height of the buffer film 30 is set to be longer than the height of the second fixing frame 12, and the buffer film 30 is provided in a manner that the buffer film 30 extends to the rear side by the height difference.

Therefore, the cushioning member 20, which rotates rearward, comes into contact with the buffer film 30 in the rising section beyond the vertical direction, not the vertical direction. At this time, in the rising section of the buffer member 20, It is possible to prevent the tearing of the buffer film 30 by reducing the pressure applied to the buffer film 30 and to further improve the shock absorption and deceleration effect by the buffer film 30. [ .

On the other hand, the bowling hole B impacted on the cushioning member 20 falls on the floor 40 due to its own weight after the cushioning. At this time, even when the cushioning member 20 is too fast The buffer member 20 pushes the bowling ball B toward the front with an excessive pressure and may cause breakage of the front plate 40A or the like or deviation of the bowling ball B from the front plate 40A.

Thus, the present invention introduces a stopping means (50) for giving a time difference to the deceleration return operation of the buffer member (20) to decelerate.

As shown in Fig. 5, the stopping means (50)

A guide plate 51 provided at both ends of the first fixed frame 11 and having guide grooves 51a of a shape corresponding to the pivoting path of the buffer member 20,

A guide pin 52 protruding from both side portions of the buffer member 20 and slidingly coupled to the guide groove 51a,

The support plate 53A is hinged to one side of the guide groove 51a in the guide plate 51 and is protruded in the direction of the front side so as not to protrude from the path of the guide groove 51a about the hinge shaft 53a, A swinging part 53B which is bent and protruded in the direction toward the other side of the upper part opposite to the receiving part 53A so as to protrude into the path of the guide groove 51a with the hinge shaft 53a as the center, A stopper 53 having a fixed portion 53b projecting rearward from an end of the guide pin 52 and rotating back and forth by the guide pin 52,

A rear end of the hinge shaft 53a is formed in a cylindrical shape having a fitting hole 54a which is provided on one surface of the guide plate 51 and has a predetermined elastic force and into which the fixing portion 53b is fitted, The inner diameter of the hole 54a is formed to be smaller than the outer diameter of the fixing portion 53b so as to press the fixing portion 53b fitted in the fitting hole 54a to temporarily stop the detachment of the fixing portion 53b. (54).

The guide groove 51a has an arcuate shape and restricts the sliding movement position of the guide pin 52 as the guide pin 52 contacts both ends of the guide groove 51a.

The guide pin 52 is inserted into the guide groove 51a and slides in the forward and backward directions along the guide groove 51a when the buffer member 20 rotates forward and backward.

The stopper 53 is rotated downward toward the rear side as the guide pin 52 rotating in the backward direction is brought into contact with the pushing portion 53B. At this time, the support portion 53A located outside the path of the guide groove 51a, (51a).

Further, as the stopper 53 is rotated downward toward the rear side, the fixing portion 53b is fitted into the fitting hole 54a of the fitting member 54. [

The stopping means 50 is configured such that when the stopper 53 is rotated downward (clockwise in the drawing) by the guide pin 52 when the buffer member 20 is pivoted rearward, And at the same time, the fixing portion 53b is fitted while expanding the fitting hole 54a.

When the cushioning member 20, which is temporarily stopped after the rearward rotation, receives pressure from its own weight and returns to the forward direction, the guide pin 52, which returns to the front, comes into contact with the receiving portion 53A. The support portion 53A instantaneously stops the guide pin 52 as the securing portion 53b is momentarily stuck out of the fitting hole 54a due to the elastic force generated when the fitting member 54 is compressed, The rotation of the member 20 is temporarily stopped and then the fixing portion 53b is released from the fitting hole 54a by the load pressure of the buffer member 20. When the fixing of the guide pin 52 is released, 20 are decelerated forward.

When a predetermined delay time is given between the stopper 53 and the fitting member 54 and the forward rotation after the backward rotation of the cushioning member 20 gives a predetermined delay time, The bowling ball B can be provided with a time margin to be able to roll toward the recovery path 43. Even if the cushioning member 20 strikes the bowling hole B, It can be rolled to a low speed and discharged to the recovery path 43 without bouncing forward.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the invention is not limited thereto. Various modifications, alterations and substitutions are possible within the scope of the present invention. Should be interpreted as falling within the scope of protection.
