The present invention is directed to a food slicer having a unitary handle.
Commercial food product slicers are widely utilized as rapid and effective means for slicing meat, cheese, vegetables and other food products. Such a slicer is shown in U.S. application Ser. No. 09/470,351, filed Dec. 22, 1999, the contents of which are hereby incorporated by reference. The slicers commonly include a rotatable, disc-like blade, and a reciprocating tray that brings the food product into contact with the rotating blade to cut a slice from the food product. The tray may be motor or manually driven, and typically includes a handle that provides a surface that can be gripped by a user to manually move the tray. It is often desired to remove the tray from the slicer body to clean food, fat, or other debris off of the tray. Once the tray is removed from the slicer, it is typically carried to a sink for rinsing and cleaning.
In most prior art slicers, the handle is attached to the body of the tray such that crevices or gaps may be formed between the handle and the body of the tray. In this case, food or other material may get trapped in the gaps or crevices, which can make the handle and tray time consuming to clean. Accordingly, there is a need for a slicer having a tray with a handle that eliminates any gaps or crevasses adjacent the handle, and is easier to clean.
The present invention is slicer having a tray with a unitary handle. In this manner, there are no crevices or voids between the body of the tray and the handle, and the tray is easier to clean. The unitary nature of the handle also improves the strength of the attachment of the handle to the tray.
In a preferred embodiment, the present invention is a slicer comprising a slicer body including a rotatable blade for slicing a product, and a tray mounted for reciprocal movement relative the slicer body and for supporting and moving the product relative the blade. The tray includes a tray body and a unitary handle. In another embodiment, the invention is a slicer including a slicer body having a rotatable blade for slicing a product and a tray for supporting the product and moving the product relative the blade. The slicer further includes a handle unitary with the tray, the handle providing a surface which a user may grip to manually move the tray.
Other objects and advantages of the present invention will be apparent from the following description and the accompanying drawings.
A slicer 10 having a tray 12 with a “V”-shaped plate or support surface 14 to receive and a support the food product to be sliced in shown in
The tray arm 16 is coupled to a carriage 22 that extends below the body of the slicer 10 and includes an upwardly-extending end plate 24 (See
The slicer 10 includes a gauge plate 32 that is movable to adjust the thickness of the slice cut by the blade 20. The gauge plate 32 supports the food product as the tray 12 is passed across the blade 20, and the gauge plate 32 is movable along a line that is parallel to the central axis B of the blade 20. The closer the gauge plate 32 is located to the plane of the blade 20, the thinner the slice cut by the slicer 10. Thus, adjusting the position of the gauge plate 32 also adjusts the thickness of the slice. The gauge plate 32 may also be moved to a fully closed position wherein the gauge plate is flush with, or extends beyond, the blade 20 to substantially cover and protect the blade 20.
As shown in
The slicer 10 includes a generally “wheel” shaped gauge plate cam 48 having a spiral groove 46 formed on a first side 49 of the cam, and a notch 47 (
When a user desires to adjust the position of the gauge plate 32 to vary the thickness of a slice cut by the slicer 10, the user manually rotates the gauge plate knob 50 which rotates the gauge plate cam 48. As the gauge plate cam 48 rotates, the coupling pin 40 slides within the spiral groove 46, which urges the coupling pin 40 and the transverse bar 38 either closer to, or further away from, the slide rod 30 along the direction of the axis B. This in turn moves the connecting rod 34 along its central axis, and adjusts the position of the yoke 33 and gauge plate 32 along the axis B (
The mechanism for attaching the carriage 22 to the tray arm 16 is shown in greater detail in
The locking arm 60 is generally “U”-shaped in side view as shown in
In order to attach the tray arm 16 to the carriage 22, the tray arm 16 is positioned over the upstanding end wall 24 of the carriage 22, as shown in
As the locking arm 60 is moved into the locking position, the transverse pin 72 of the locking arm 60 is pulled out of the notch 54 in the gauge plate cam 48, as can be seen in
The tray arm 16 also includes a vertically-extending slot 84 on its outer body 80 (See
Once the tray arm 16 is received in the locking arm 60 and the locking arm 60 is moved to its locking position, the slicer 10 may be moved out of its home position, and operated such that the tray 12 and carriage 22 reciprocate along the slicing path A. The slicer includes a retaining bar or track 78 that extends along the majority of the slicing path A, and the retaining bar 78 includes an upper portion 79 and a lower portion 81. The carriage 22 includes a roller 83 (
As shown in
Thus, when the tray 16 is in a non-home position, the retaining bar 78 blocks the locking arm 60 from moving to its release position. If the tray 12 were to be attempted to be lifted off of the carriage 22 when the tray 12 is not in the home position, the cross bar 59 of the tray arm 16 would engage the top flange 64 of the locking arm and attempt to pivot the locking arm 60 to its release position. However, the lower portion 81 of the retaining bar 78 would block the locking arm 60 from pivoting, and thereby block the locking arm 60 from moving to its release position. Thus when the locking arm 60 is in its locking position and the tray 12 is in a non-home position, the tray arm 16 is locked into place in the locking arm 60 and cannot be removed from or placed into the locking arm 60.
During normal operating conditions, the carriage 22 and tray 12 reciprocate along the slicing path A to cut slices off of the food product. The gauge plate knob 50 may be adjusted to vary the thickness of the slices. The locking arm 60 retains the cross bar 59 of the tray arm 16 in the notch 68 of the locking arm, and the locking arm is maintained in its locking position by the retaining bar 78. However, the tray 12 and tray arm 16 must be periodically removed from the slicer in order to clean or service the tray arm 16. The interlock mechanism prevents the tray 12 from being removed from the slicer 10 except when certain conditions are met.
In order to uncouple the tray 12 from the slicer 10, the tray 12 must first be moved to the home position. The tray 12 and carriage 22 are shown in the home position in
In order for the locking arm 60 to pivot to its release position, the transverse pin 72 must be aligned with the notch 54 in the gauge plate cam 48. In order to align the notch 54 with the transverse pin 72, the gauge plate cam 48 is rotated by the knob 50 until the gauge plate cam 48 is in the position shown in
Accordingly, the interlock mechanism ensures that two conditions must be met before the tray 12 can be uncoupled from the carriage 22: (1) the tray 12 and carriage 22 must be located in their home position; and (2) the gauge plate 32 must be located in its fully closed position. Once both these requirements are met, the nut 88 can be loosened and moved away from the tray arm 16, and the tray arm may then be lifted vertically off of the carriage 22 (
The tray 12 may then be carried to a sink for cleaning or maintenance. The only component of the interlock mechanism located on the tray 12 is the cross bar 59. In this manner, the number of parts of the interlock mechanism on the tray 12 is minimized, which minimizes the exposure of the parts of the interlock mechanism to water and detergents when the tray 12 is washed. Furthermore, the cross bar 59 is protected on three sides by the outer body 80, which protects the retaining bar from external forces.
When the tray 12 is uncoupled from the carriage 22, the locking arm 60 is in its position shown in
After the tray 12 is cleaned or serviced, it may be coupled to the carriage 22. In order to attach the tray 12 to the carriage 22, the tray arm 16 is positioned over the upstanding end wall 24 of the carriage 22, as shown in
When the tray 12 is coupled to the carriage 22, the locking arm 60 is pivoted into its locking position (as urged by the cross bar 59). Thus, the transverse pin 72 of the locking arm 60 is pulled out of the notch 54 in the gauge plate cam 48, which enables the gauge plate cam 48 to be rotated and the position of the gauge plate 32 to be adjusted. Furthermore, when the locking arm 60 is in its locking position, lower portion 61 of the lower arm is located below the lower portion 81 of the retaining bar, which enables the carriage 22 and tray to move along the slicing path A without engaging the end surface 65 of the cross bar 78. Thus, after the tray 12 is mounted onto the carriage 22, the gauge plate 32 may be adjusted to achieve the desired thickness of slices, the slicer 10 may be activated and slicing operations commenced. The carriage 22 and tray 12 then reciprocate along the slicing path A to slice the food product received in the tray 12.
If an interlock mechanism is not desired in the slicer, the assembly of the slicer described herein can be easily modified to produce a slicer lacking an interlock. For example, the locking arm 60, spring 76 and cover 87 may not be mounted onto the slicer if an interlock is not desired. The carriage 22, gauge plate cam 48 and other components need not be changed. Thus, most of the parts in a slicer lacking an interlock are the same as the parts of a slicer having an interlock, which reduces assembly costs.
As shown in
The handle 18 is preferably attached to the body of the tray 12 at two attachment points 100, 102, and extends generally vertically. In this manner, the handle 18 and the body of the tray 104 form an opening 108. A user may extend his or her fingers or hand through the opening 108 such that the handle 18 can be easily gripped in the user's palm for moving the tray 12 along the slicing path. The handle 18 is preferably generally arcuate in side view; that is, the handle extends between the attachment points 100, 102 in a generally arcuate shape. The tray body 104 also preferably includes a recessed area 110 located between the attachment points 100, 102 to increase the effective size of the opening 108, which makes it easier for a user to fit his or her hand through the opening 108. As shown in
In an alternate embodiment shown in
The handle 18 and tray body 104 are preferably integrally formed of a single cast piece of material, such as aluminum. However, the tray 12 may be made from a variety of materials, including but not limited to various metals, plastic, fiberglass, composite materials, and the like.
Having described the invention in detail and by reference to the preferred embodiments, it will be apparent that modifications and variations thereof are possible without departing from the scope of the invention.
